Full textAbstract:
The pivotal role of inflated responsibility beliefs in the maintenance and treatment of obsessive-compulsive disorder (OCD) has been clearly demonstrated (Rachman, 1993; Salkovskis, 1998; Shafran, 1997; van Oppen & Arntz, 1994). Yet little is known about the origins of these beliefs, their contribution to a sense of inflated responsibility or the symptoms of OCD, or the contribution of personality to inflated responsibility and to OCD, The aims of this thesis were to investigate a model of the inter-relationships among the personality dimensions of neuroticism and psychoticism, inflated responsibility and OCD, and the origins of inflated responsibility to inflated responsibility and to OCD. In order to achieve these aims, a scale was developed to assess the origins of inflated responsibility based upon the five pathways proposed by Salkovskis, Shafran, Rachman, and Freeston (1999) and the additional domains of guilt, vigilance and thought-action fusion (Shafran, Thordarson, & Rachman, 1996; Shafran, Watkins & Charman, 1996; Tallis, 1994). Eighty-four participants with OCD (age M = 43.36) and 74 control participants (age M =37.14) volunteered to participate in the two studies of this thesis. The aim of Study 1 was to develop and validate a measure of the Origins of Inflated Responsibility (OIR). The results of the first study yielded a 25-ttem scale, the Origins of Inflated Responsibility Questionnaire (OIRQ) with five independent factors: responsibility, strictness, protection from responsibility, critical incidents, and peer blame which demonstrated both internal reliability and temporal stability over a 2-week period. In Study 2, participants also completed the Responsibility Attitudes Scale (Salkovskis, Wroe, Gledhill, Morrison, Forrester, Richards, ct al. (2000) (a measure of inflated responsibility), the Padua Inventory (Sanavio, 1988) (to measure of the symptoms of OCD)y and the Eysenck Personality Inventory-Revised (Eysenck & Eysenck, 1991). Multivariatc Analysis of Variance revealed that the OCD group scored higher on all variables than the control group except for strictness where the groups were not different, and psychoticism where the OCD group scored lower. A series of Multiple Regression analyses revealed that both group and the OIR contributed to inflated responsibility (R2 = .56). When all variables, OIR, inflated responsibility and neuroticism were entered as predictors of OCD, 60% of the variance in OCD was explained however, 49% of the variance was shared by the independent variables suggesting the presence of some underlying construct. Structural Equation Modelling, where all the constructs in the model were examined simultaneously, revealed that neuroticism contributed to the OIR, inflated responsibility and OCD. The OIR were also significant predictors of inflated responsibility and indirectly through inflated responsibility predictive of OCD. The OIR also directly predicted OCD and when the total effects are considered, their contribution was greater than the total effect for inflated responsibility alone. The results of these studies provide good support for the origins of inflated responsibility proposed by Salkovskis et al. (1999), as measured by the OIRQ developed for use in the current thesis. The results also support the contribution of inflated responsibility and neuroticism, as well as the OIR, to OCD, The large amount of variance shared by the OIR, inflated responsibility and neuroticism suggest that there might be some underlying construct, perhaps of a biopsychosocial nature, that requires further investigation for its role in the onset and maintenance of OCD. The clinical relevance
of these findings is discussed in terms of early prevention strategies and interventions.

Full textAbstract:
The question posed in this work is how one would model and predict the rotational spectrum of open-shell open-shell van der Waals complexes. There are two secondary questions that arise: the nature of radical-radical interactions in such systems and the modelling of the large amplitude motion of the constituent molecules. Four different systems were studied in this work, each providing part of the answer to the main question. Starting with the large amplitude motion, there are two theoretical approaches that may be adopted: to either model the whole complex as a semi-rigid molecule, or to perform quantum dynamical calculations. We recorded and analysed the rotational spectrum (using Fourier transform microwave spectroscopy) of the molecule of tertiary butyl acetate (TBAc) which exhibits a high degree of internal rotation; and of the weakly-bound complex between a neon atom and a nitrogen dioxide molecule (Ne-NO2). We used the semi-rigid approach for TBAc and the quantum dynamical approach for Ne-NO2. We also explored the compatibility of these two approaches. Moreover, we were able to predict and analyse the fine and hyperfine structure of the Ne-NO2 spectrum using spherical tensor operator algebra and the results of our dynamics calculations. To explore the nature of the interactions in an radical-radical van der Waals complex we calculated the PESs of the possible states that the complex may be formed in, when an oxygen and a nitrogen monoxide molecule meet on a plane using a number of high level ab initio methods. Finally, our conclusions were tested and applied when we performed the angular quantum dynamics to predict the rotational spectrum of the complex between an oxygen and a nitrogen dioxide molecule, and account for the effect of nuclear spin statistics in that system.

This thesis details research undertaken in the investigation of the open-shell open-shell Van der Waals complexes between nitric oxide (NO) and oxygen (O2) and between nitrogen dioxide (NO2 ) and oxygen (O2 ). The Fourier transform microwave spectroscopy technique was used during the experimental work. Spectra were recorded for a mixture of NO and O2 over the frequency range 7.0 to 18.2 GHz. Detailed ab initio calculations have been performed on the potential energy surface of both NO-O2 and NO2-O2 using Multi-reference Rayleigh Schrodinger Second Order Perturbation Theory. These calculations were performed for the four distinct states of NO-O2, 2A", 4A", 2A' and 4A', and for the two distinct states of NO,sub>2-O2, 2A and 4A. Predicted rotational spectra have been generated by modelling the systems with a rigid-rotor Hamiltonians. The effective Hamiltonians included the rotational Hamiltonian, ℋrot, fine structure terms and hyperfine structure terms. It was not possible, for rationalizable reasons, to fit the predicted spectra for NO-O2 to the experimental observations. Experimental details, calculation methods and rotational theory are discussed in the main body of the thesis. Predicted spectra, relevant calculations and other data is presented in the appendices.

Full textAbstract:
The microwave spectrum of the open-shell van der Waals complex NO-HF has been recorded in the region 6-20GHz using a pulsed nozzle Fourier transform microwave spectrometer. This is the first observation of the microwave spectrum of a open-shell van der Waals complex between two molecules. The spectrum exhibits a rich hyperfine structure with the observation of intermolecular hyperfine interactions in an isolated system providing a sensitive probe of electron transfer in the complex. The spectrum consists of four fine structure transitions 5/2(e)-3/2(e), 3/2(e)-1/2(e), 5/2(f)-3/2(f), 3/2(f)-1/2(f) which have been fitted to a semi-rigid Hamiltonian developed to include the effects of the orbital and spin angular momenta of the unpaired electron on NO. A new treatment to account for the intermolecular hyperfine interaction was developed. The structure of the complex has been determined and is significantly bent with an angle of between 37 degrees and 49 degrees between the NO internuclear axis and the a-axis of the complex. The Renner-Teller parameter, epsilon 2, is very large and negative having the value of -10 449.32(4)GHz indicating that configuration with the unpaired electron in the plane of the complex is more stable. The analysis of the hyperfine interactions of the hydrogen and fluorine nuclei uses two constants for each nucleus, one for the spatial relationship between the magnetic moments of the unpaired electron and the nuclear magnetic moment and a Fermi-contact term. The Fermi-contact term for hydrogen is the first strong evidence of intermolecular charge transfer in an isolated van der Waals molecule.

The aim of this study was to determine whether a relationship exists between
the use of self-regulation by the tertiary distance learner and his or her
academic achievement in a specific academic course unit. To attain this aim,
a literature study was undertaken to: a) define and describe distance learning,
b) describe the nature of learning, c) describe the nature of self-regulated
learning and its implications for distance learning, and d) define and classify
learning strategies and indicate the relationships between self-regulated
learning, the use of learning strategies, and successful learning.
Literature indicated a positive relationship between self-regulation, the use of
learning strategies, learning success, and academic achievement: learning
success results whenever pre-formulated learning goals are attained through
the use of self-regulation and applicable learning strategies; and attainment of
learning goals results in positive academic achievement. Self-regulated
learners, who plan their learning, formulate learning goals, motivate
themselves intrinsically, instruct themselves, apply different learning
strategies to attain learning goals, continuously monitor and self-evaluate
themselves during the learning process, are able to attain the formulated
learning goals successfully and perform well academically. The literature
review also revealed a high level of self-regulation as one of the prerequisites
for performing successfully as a distance learner. Planning personal learning
goals, using a variety of learning strategies to attain the goals, determining
the correct personal learning tempo, monitoring learning progress, and self
evaluating learning outcomes are typical characteristics of self-regulation
necessary for effective distance learning and academic progress.
The population of the research includes the PU vir CHO - Open Learning
Academy-learners registered for the Further Diploma in Educational
Management, module PSD 511 (Teaching and Learning) in the North West
region of South Africa. The total number of students attending the three
contact sessions in September 2000 at five sentra in the North West
Province, and who participated in the research, was 143. Three
questionnaires were used to obtain personal information, as well as
information regarding self-regulation in the learners, namely, a biographical
questionnaire, the Motivated Strategies for Learning Questionnaire (MSLQ)
and the Self Regulated Learning Questionnaire (SRLQ).
The data was statistically analized by means of: a) factor analyses, b)
multiple regression analyses, and c) stepwise regression analyses.
A difference was found to exists between the variables that determine the
academic achievement of successful versus unsuccessful distance learners.
Successful distance learners have better developed self-regulated learning
skills than unsuccessful distance learners.Thesis (M.Ed.)--Potchefstroom University for Christian Higher Education, 2001

Full textAbstract:
L'objectif de cette thèse est d'évaluer l'interdépendance macroéconomique entre pays développés sur les récentes décennies et, en particulier, à la suite de la crise financière de 2007-09 aux États-Unis. Pour cela, on utilise différentes hypothèses de modélisation dans les trois chapitres principaux que constituent la thèse permettant de capturer la dimension internationale des cycles économiques : modèle VAR en panel permettant de modéliser l'interdépendance entre les pays directement, modèle VAR simple en utilisant des variables domestiques et étrangères, et modèle DSGE à 2 pays permettant de modéliser directement les mécanismes réels et financiers qui lient les pays entre eux. Notre résultat principal est que la dimension internationale est importante pour expliquer la dynamique macroéconomique des pays développés sur les trois dernières décennies, que les variables soient réelles, nominales ou financières. Néanmoins, le rôle des facteurs étrangers ne croit pas dans le temps comme on pourrait le penser avec l'accentuation de la mondialisation de ces dernières décennies. Aussi, en regardant les crises économiques récentes aux États-Unis et de la zone euro, nous confirmons que la crise financière américaine de 2007-09 présente un choc plus important comparé aux standards historiques, qui s'est propagé à la zone euro à travers les liens financiers internationaux. Au contraire, la crise des dettes publiques de la zone euro de 2011 est un choc relativement standard, similaire aux chocs observés pendant la crise du Système Monétaire Européen (SME) de 1992-93, et affectant principalement les économies européennesThe aim of this thesis is to evaluate macroeconomic interdependence between developed economies over the recent decades and, in particular, following the 2007-09 US financial crisis. For that purpose, we use several modeling assumptions across the three main chapters of the thesis to capture the international dimension of business cycles across countries: panel VAR model to model countries interdependence directly, simple VAR model with both domestic and foreign variables, and two-country DSGE model to model the real and financial mechanisms that link countries together. Our main result is that international dimension is important to explain the macroeconomic dynamics of developed economies over the last three decades and for either real, nominal and financial variables. Nevertheless, the role of foreign factors does not grow over time as would be expected with the increase in globalization of the recent decades. Also, looking at the recent economic crises in the US and the euro area, we confirm that the 2007-09 US financial crisis features a bigger shock relative to historical standards, which propagated to euro area economies through international financial linkages. In contrast, the 2011 euro area sovereign debt crisis features a standard shock, comparable to those observed in previous European crises like the 1992-1993 ERM crisis, and affecting mostly European economies

Thesis (MEd)--Stellenbosch University, 2015.ENGLISH ABSTRLiterature shows that exposure to community development projects is a way for people to realize, enhance and improve their own value. The Words open Worlds (WOW) project, part of Stellenbosch University’s community interaction projects, tries to uplift the lives of people through recruitment actions, retention programs, as well as well-structured partnerships with suitable role players. The purpose of this study was to determine the perceptions regarding the WOW project of undergraduate Stellenbosch University’s students within the Faculty of Arts and Social Sciences who come from schools that are actively involved with the WOW project. An interpretative research paradigm and a case study were utilized in order to collect qualitative data from focus groups. The data, which was analyzed through the process of content analysis, demonstrated that the support to prospective WOW students as well as the mentoring and retention programs for current WOW students, made life easier for the participants. Improvements mentioned, included more frequent meetings with current WOW students and the cultivation of a greater awareness of the possibilities which the WOW project offers to students. This can be achieved by improved collaboration with education departments, synergies with similar school outreach projects, extended mentorship programs and more social gatherings organized for WOW students. From the results of the data analysis it became apparent that the perceptions regarding the WOW project of the target focus groups were positive. Due to the restricted participation, however, the results cannot be generalized.
AFRIKAANSE OPSOMMING: Verskeie bronne wys daarop dat die blootstelling aan gemeenskapsontwikkelingsprojekte ’n manier is om mense hul eiewaarde te laat besef en uitbou. Die Woorde Open Wêrelde (WOW)-projek, ʼn Universiteit Stellenbosch gemeenskapsinteraksieprojek, streef daarna om met projek-aksies soos werwingsuitreike en retensieprogramme, asook deur gestruktureerde vennootskappe met geskikte rolspelers, ʼn positiewe verskil in mense se lewens te maak. Die doel van dié studie is om die persepsies aangaande die Woorde Open Wêrelde-projek te bepaal van voorgraadse studente aan die Universiteit Stellenbosch wat afkomstig is van skole waar die WOW-projek werksaam is, en wat tans binne die Fakulteit Lettere en Sosiale Wetenskappe studeer. ʼn Interpretatiewe navorsingsparadigma en ʼn gevallestudie as navorsingsontwerp is gebruik om kwalitatiewe data met fokusgroepe te versamel. Die data, wat verwerk is deur die proses van inhoudsanalise, het getoon dat die deelnemers se lewens aansienlik vergemaklik is deur die ondersteuning wat verleen is aan die voornemende WOW-studente, asook deur die mentorskaps- en retensieprogramme vir huidige WOW-studente. Meer gereelde ontmoetings met studente en ’n groter bewusmaking van die moontlikhede wat die WOW-projek vir studente bied, was voorstelle vir verbetering van die WOW-projek. Dit kan teweeg gebring word deur groter samewerking met onderwysdepartemente, sinergieë met soortgelyke skoolprojekte, uitbreiding van die mentorskapprogram en deur meer sosiale ontmoetingsgeleenthede. Uit die resultate wat die analise van die data opgelewer het, het duidelik geblyk dat die persepsies van die betrokke teikengroep wat aan fokusgroepe deelgeneem het positief is jeens die WOW-projek. Weens die beperkte steekproef kan hierdie resultate egter nie noodwendig veralgemeen word nie.

Full textAbstract:
Att förstå en konsument och vad som driver den har varit många forskares mål att svara på. Komplexiteten i de mänskliga processerna och konsumentens ständigt utvecklande normer och vanor är även något som försvårar processen att kunna förstå köpmönster och beteenden. Om det gick att förstå konsumenten bättre, så hade både företag och kund kunnat lära känna sig- och sina köpbeteenden bättre. Oftast vet inte ens konsumenten varför dennes konsumtion ser ut som den gör, och om konsumenten skulle ha en lite större förståelse över sin egen konsumtion borde vi kunna se ett mer ansvarsfullt konsumerande och en mer förutsägbar efterfrågan. Konsumenter blir dagligen påverkade av reklam för att konsumera mera vilket sedan styr de olika faktorerna som gör att de konsumerar på olika sätt. Något som har en stor inverkan är kundens första val i en butik vilket kan leda till att konsumenten antingen är konsekvent i sina köp eller konsumerar mer än de egentligen tänkt från första början. Studiens syfte är att påvisa att det finns skillnader i köpbeteendet hos konsumenter som väljer antingen en ohälsosam eller hälsosam vara som sitt första val. Studien har använt sig av en kvantitativ forskningsstrategi med 150 respondenter i en verklig miljö för att kunna återspegla konsumenternas beteende så trovärdigt som möjligt. Studien visar att konsumenter påverkas beroende på vad de gör för första val i en butik. Urvalsgruppen tenderar att fortsätta handla ohälsosamma varor ifall deras första val har varit något ohälsosamt, de förblir alltså konsekventa i sina köpbeteenden. Konsumenter som istället väljer något hälsosamt som första val fortsätter att vara konsekventa och handla en större andel hälsosamma varor resterande tid i butiken. Studien visar även att personer som tar beslutet att handla något tidigare under sin köpresa i butiken, köper sedan fler varor totalt. Studiens empiriska resultat påvisar ännu en gång att konsumenter går att manipulera till att konsumera annorlunda, att val vinner över inställning, och att en ökad förståelse för människan och dess konsumtionsbeteende skulle kunna bidra till en mer ansvarsfull konsumtion.Understanding a consumer and what drives it has been a goal many researchers strive to answer. The complexity of the human processes and the consumer's ever-evolving norms and habits are also something that makes the process difficult to understand buying patterns and behaviors. If you could understand the consumer better, both companies and customers would have been able to get to know themselves and their purchasing behavior better. Usually, even the consumer does not know why his consumption looks the way it does, and if he could have a little greater understanding of his own consumption, we should be able to see a more responsible consumer and a more predictable demand. Consumers are daily influenced by advertising to consume more, which then controls the various factors that cause them to consume in different ways. Something that has a big impact is the customer's first choice in a store, which can lead to either being consistent in their purchases or consuming more than they actually intended from the beginning. The purpose of the study is to create an understanding of the difference in the buying behavior of consumers who choose either an unhealthy or healthy item as their first choice. The study has used a quantitative research strategy with 150 respondents in a real-world environment to reflect consumer behavior as credibly as possible. The study shows that consumers are affected depending on what their first choice is in a store. The sample group tends to continue to buy unhealthy goods in case their first choice has been somewhat unhealthy, they remain consistent in their buying behavior. Consumers who instead choose something healthy as their first choice continue to be consistent and shop a greater proportion of healthy products their remaining time in the store. The study also shows that people who make the decision to shop earlier during their purchase trip in the store, then buy more products in total. The study's empirical results show once again that consumers can be manipulated into consuming differently, that choices win over attitudes, and that an increased understanding of the human being and its consumer behavior would probably contribute to a more responsible consumption.

Full textAbstract:
Many students in South Africa are unable to cope with the academic demands of tertiary
education as they are not fully prepared for Higher Education (HE). Various inefficiencies in
the South African HE system have been identified, including low throughput rates, student
dissatisfaction, unsatisfying graduation rates, learner dropouts, learner repetition, motivation,
self–efficacy, attitude, personality differences, maturation, the retention of failing learners and
unit costs. Student performance and satisfaction cause concern for the government and the
HE sector.
The purpose of this study is to understand student satisfaction amongst Open Distance
Learning BEd Hons students. It further aims to improve student satisfaction and quality in
the programme by recognising the context sensitive needs, expectations and experiences of
students from different cultural–language groups, as well as constructing guidelines to
improve satisfaction. The purposeful sampling consisted of Second year BEd Hons teacherstudents
enrolled for open distance learning at the School for continuing teacher education
(SCTE). A total of 34 students participated in the study. This number comprised of fifteen
students from the focus–group interviews and nineteen students who completed open–ended
questionnaires. Students were chosen according to three criteria dimensions: major
language groups, gender and number of years teaching experience. This study followed a
qualitative investigation of two semi–structured, open–ended focus–group interviews in the
format of conversations, as well as documentary analysis of the teaching and learning policy
of the North West University (NWU), and an open–ended questionnaire. The data were taperecorded
for accurate transcription and analysed by using Atlas.ti. Through the use of
Atlas.ti, I constructed categories of recurring patterns in the dataset, and explored the
relationships of these categories. Different strategies were used to enhance validity and
reliability respectively.
The findings indicated that students’ satisfaction with HE environment is influenced by the
quality of the programmes offered to them, communication between lecturers/facilitators and
students, environment at the learning centres and the support that students received from
HEI. The students in their capacity as clients with Higher education institutions (HEIs) are
influenced by the support they receive from their work environment, as well as the level of
appreciation they receive from HEI regarding their own culture and values. They also value
iii
the environment they experience during course facilitations at the HEIs. The various student
attributes also play a significant part in their satisfaction levels towards the HEIs.
Findings also highlighted that students were not satisfied with the support they received from
the Open distance learning (ODL) unit. It is clear that the students’ perception of the quality
of the programme influences their level of satisfaction. Students are mostly satisfied with the
quality of the programme but they feel the communication as well the support from HEI and
ODL is not adequate. The students indicated that HEI and ODL do not display sufficient
understanding and concern for students. They feel there should be a greater commitment
from HEI and ODL to understand and consider the profiles of the students. HEI and ODL
should actively consider the background, culture, values, attributes, and personal, as well as
domestic circumstances of their students. The BEd Hons programme is a valuable and
popular programme, but the responsibility rests with both HEI and ODL to ensure that both
the quality and delivery of this programme are enhanced and improved so as to guarantee
higher levels of satisfaction amongst students.Thesis (Ph.D. (Education))--North-West University, Potchefstroom Campus, 2012.

Full textAbstract:
I mitt examensarbete har jag undersökt hur min låtskrivningsprocess påverkats när jag skrivit låtar i olika stämningar på gitarren. Jag har på senare tid ofta upplevt att jag lätt fallit tillbaka i gamla vanor och mönster när jag skrivit musik. Detta har gjort att låtskrivningsprocessen känts oinspirerande och jag har stundtals haft svårt att ta mig vidare i processen. Mitt syfte med arbetet har varit att se om jag genom att skriva musik i en öppen stämning kan bryta gamla mönster och hitta nya sätt att utrycka mig musikaliskt. Fokuset i arbetet har legat på harmonik, melodi och den kreativa processen. Jag har inte haft mycket erfarenhet i att spela eller skriva musik i andra stämningar än standardstämning innan detta arbete och valde därför att ta tillfället i akt och förkovra inom ämnet. Arbetet har resulterat i inspelningar av tre stycken egenskrivna låtar i stämningarna öppet G, dadgad samt standard stämning. I arbetet går jag igenom processen från låtidé till färdig låt och tar upp vilka problem respektive möjligheter jag funnit i varje stämning samt låtskrivningsprocess. I min stuide har jag hittat flera nya musikaliska utryck och verktyg. Jag har även blivit medveten om vikten av att begränsa sig när det kommer till låtskrivning. Jag märkte att kreativiteten och inspirationen frodades när jag skrev låtar i stämningar jag inte var van att spela i.

Full textAbstract:
According to the South African White Paper 5 on Early Childhood Development (ECD), the initiative of the Department of Education (DoE), whereby grade R is being implemented as part of compulsory education, is directed at the poorest of the poor. Grade R teachers responsible for the education of 5/6 year old learners will therefore have to possess knowledge and skills to enable them to lead grade R learners from deprived circumstances to optimal development and learning readiness. For under-or unqualified Foundation Phase teachers who work and live in rural areas, distance learning is often the only option for professional development and concurrent increase in compensation. The School of Continuing Teacher Education of the North-West University designed an open distance learning model to provide in the educational needs of under and unqualified teachers. The Foundation Phase Curriculum within the Professional Educator Development programme of the Advanced Certificate in Education presented by the North West University (hereafter referred to as the NWU Foundation Phase ACE programme) is delivered via open distance learning. The National Curriculum Statements (Grade R-9) include grade R to three in the Foundation Phase Curriculum and therefore the NWU Foundation Phase ACE programme will be a financially viable option to train a large number of grade R teachers to provide in the need for qualified grade R teachers.
This study investigates the way in which the NWU Foundation Phase ACE programme enables grade R teaching competency as programme outcome. To attain the research aims of the study a literature and empirical study were performed. The research aims of the literature study include the establishment of the knowledge, skills and attitudes to be included in a training programme with the aim of capacitating grade R teachers to facilitate the optimal development of five/six year olds from deprived circumstances. The literature is further researched to determine national and international criteria for effective design and content for training programmes for teachers of 5/6 year old learners. Through the literature study the criteria for effective training programmes for grade R teachers are determined and more specific the criteria for the effective implementation of distance learning for the training of grade R teachers. A comparative study between the NWU Foundation Phase ACE programme and similar distance learning programmes implemented internationally also serves as benchmarking for the evaluation of the NWU Foundation Phase ACE programme. Findings from the literature study serves as benchmark for the evaluation of the NWU Foundation Phase ACE programme and for the designing of questionnaires as measurement instruments for the empirical study. The empirical research has as its first aim to determine how the NWU Foundation Phase ACE programme provides grade R teacher-students the opportunity to develop the necessary knowledge, skills and attitudes to facilitate the optimal development and learning readiness of five/six year olds from deprived circumstances. Secondly the empirical study aims to determine how the design and content of the NWU Foundation Phase ACE programme accommodates the profile and educational needs of the target population namely the teacher who will be responsible for the education of five/six year old learners from deprived circumstances.
Although a combination of both qualitative and quantitative statistical methods is used in the empirical study, this evaluation research is primarily seen as a quantitative study grounded in the post-positivist epistemology. The mixed method serves as verification of findings on the data. Empirical data were captured by means of questionnaires comprising structured and open questions. Data captured through structured questions were statistically analysed Iwhile responses in open questions were interpreted qualitatively by the researcher. Data triangulation serves as verification of findings as the researcher gathered data from three study populations namely the NWU Foundation Phase ACE teacher-students, the facilitators who facilitate the NWU Foundation Phase ACE programme at the various contact centres countrywide as well as lecturers presenting a similar Foundation Phase ACE programme at other tertiary institutions in the country. A comparison of responses from the structured questions and open questions with data from related literature further provides for methodological triangulation and verification of findings.
Data from the literature study as well as from all three study populations in the empirical investigation converged regarding inadequacies in the way the design and content of the NWU Foundation Phase ACE programme enable the development of grade R teaching competencies as outcome. Deficiencies were identified in the way the programme accommodates the situated and personal circumstances of the teacher student. The opportunity provided by programme design and content for an inexperienced grade R teacher-student to develop grade R knowledge and skills through experience learning, social learning and learning through reflection within the grade R teaching and learning context, was also found to be lacking. Recommendations based on the findings are made for consideration of future programme design.Thesis (M.Ed.)--North-West University, Potchefstroom Campus, 2010.

Resumo: Esta pesquisa lança um olhar sobre os espaços abertos de uso coletivo como articuladores da forma, uso e apropriação da cidade contemporânea, dando continuidade à linha de investigação iniciada na dissertação de mestrado, na qual o conceito da Arquitetura da Fronteira envolveu o redesenho dos espaços que fazem a mediação entre os territórios de domínio público e os de domínio privado. A hipótese da pesquisa é a existência de um potencial inerente aos espaços abertos de uso coletivo para a qualificação socioambiental dos lugares urbanos. O objetivo do trabalho é identificar os potenciais de qualificação socioambiental de partes consolidadas da cidade contemporânea pelo redesenho dos seus espaços abertos, à medida que se desenvolve uma maior sensibilidade na percepção da fronteira público-privada, conjugada à aplicação de estratégias processuais de projeto participativo. A pesquisa teve caráter exploratório e valeu-se de uma pesquisa-ação que se iniciou com um estudo de caso de natureza instrumental. O campo experimental selecionado foi a área central de um espaço universitário - a Cidade Universitária Zeferino Vaz, campus da Universidade Estadual de Campinas - por ter as características de um fragmento urbano que incorpora uma gama de interesses e conflitos ricos para investigação e estudo do tema proposto. A partir da investigação da área da Praça do Ciclo Básico, espaço aberto de grande representatividade para o campus e ponto referencial do seu traçado urbanístico, foi realizada uma experiência piloto, que teve início no projeto para requalificação desta praça. As diretrizes estabelecidas para aquele projeto se expandiram e foram aplicadas em outros projetos nos campi da Unicamp. A fundamentação teórico-conceitual do trabalho baseou-se no estado da arte das teorias e conceitos do Desenho Urbano e, para a análise ambiental, nos conceitos do Modelo Ecológico do Ambiente Urbano. Na experiência projetual piloto, a abordagem dos espaços abertos como protagonistas do espaço do campus representou uma inversão na cultura da universidade brasileira e da cidade contemporânea, que prioriza as edificações implantadas como objetos autônomos do seu contexto local, relegando o tratamento dos espaços abertos de uso coletivo a planos secundários e residuais. A valorização dos espaços abertos de uso coletivo foi incorporada de forma inédita como uma das prioridades da universidade para melhoria da qualidade de vida da sua comunidade. A metodologia de pesquisa-ação mostrou-se adequada ao processo de projeto urbano, na medida em que viabilizou a interação com a comunidade envolvida e possibilitou também a aproximação da dimensão de pesquisa teórica com a práxis da produção arquitetônica e urbanística. Os resultados obtidos incentivam a realização de outras análises críticas e diagnósticos que embasem propostas projetuais que criem cenários que qualifiquem os espaços abertos de uso coletivo do meio urbano
Abstract: The present work focuses on open spaces for collective use as articulators of the shape, use and appropriation of the contemporary city. It is the continuity of a research that started in the master thesis, where the concept of the Architecture of the Boundary involved the redesign of the territories that mediate the public and the private realms. The hypothesis of this research is the existence of a potential inherent to the collective use open spaces for the social and environmental qualification of the urban places, in the viewpoint of Urban Design. Its aim is to identify the potentials for socioenvironmental qualification of contemporary city's consolidated parts, through the redesign of its open spaces, to the extent that develops greater sensitivity in the perception of public-private boundary, in conjunction to the application of procedural strategies for participatory design. The research took an exploratory character, developing an action research that began with a case study of instrumental nature. It was selected a university space, as an experimental field: the campus of Universidade Estadual de Campinas, in São Paulo State, Brazil, called Cidade Universitária Zeferino Vaz. The reason for selecting this objet of study is due to its characteristics of an urban fragment that incorporates a range of interests and conflicts rich for the investigation of the proposed subject. Starting from the analysis of the open spaces of that campus, it was held an experiment for the requalification of its central square - Praça do Ciclo Básico, focal point of the campus' urban fabric and social life. The theoretical and conceptual foundation of the work was structured on the state of the art of the theories of Urban Design and the environmental analysis was based on the concepts of the Ecological Model of the Urban Environment. The valuation of open spaces for collective use was incorporated as one priority of the university to improve the quality of life of its community, through the process of participatory design. The action research methodology proved to be suitable for the urban design process, insofar as it enabled the interaction with the community involved. It also brought together the theoretical research dimension and the praxis of urban and architectural production. The results that were reached encourage other critical analysis that may result in design proposals that generate urban scenarios conceptually consistent and that qualify the open spaces of collective use of the urban environment

This study titled School Model of Norrberga- a New Model of School. Some opinions that six pupils in the sixth grade have of their school is an explorative study. The purpose of this study is to some extent explain the ideas behind this quite spectacular model of school and the intentions of the City Council of Norrberga as they decided that all the schools that were to be renovated or built in the town of Norrberga had to follow a specific script. As I first visited The Moonlight School I was puzzled. How do the teachers work it out? But, above all: Do the pupils work it out? What do they think about their school? When I was to write my final essay I wanted to try to sort this school out in more scientific terms. There is a nice, warm atmosphere at the school and the pupils make good results. The school has an open architecture and there are seven classes with 60 pupils each and three teachers per class. Pupils and teachers work together in various work units in different areas of the school. In this newly built school with hardly any inside walls, or walls made of glass, the pupils in the sixth grade experience new ways of teaching. In order to find out how these pupils, having experienced both the old Moonlight School and the new model, looked upon their new school I wanted to perform individual interviews with some of them. I also visited the school a couple of days to observe the atmosphere and how they organised the day. While analysing the collected material trying to describe the school I found support in the theories of Michel Foucault and John Dewey as well as scientific reports about school buildings and history of schooling. I selected those I found most significant for this study. I found that the pupils mainly are satisfied with their school. Those having experienced all their schooling there do not have problem with the lack of not transparent walls nor with people and transports passing through the spacious educational area. The community wanted to build smaller schools with more efficient use of the facilities. There is also an intention of developing new ways of teaching better adapted to current teaching methods and curriculum.

Full textAbstract:
Även om marknaden för finansiella tjänster digitaliseras i en allt högre takt finns det fortfarandeinträdesbarriärer för nya aktörer som vill utveckla betal- och kontotjänster för konsumenter. Ettav dessa hinder är att infrastrukturen som används för tjänsterna ägs och förvaltas av deetablerade aktörerna vilket försvårar för en fri konkurrens. Som ett led i att bland annat öppnaupp den europeiska finansiella tjänstesektorn och främja innovation har EU därför infört ettandra betaltjänstdirekt (PSD2) som trädde i kraft under 2018. Direktivet omfattar etableradebanker och finansbolag och tvingar dem att exponera betaltjänster och kontoinformation tilltredjepartsleverantörer när kunden gett sitt medgivande. Införandet av PSD2 kommer förändraspelplanen för både etablerade och nya aktörer när befintliga affärsmodeller utmanas i takt medatt kunderna själva väljer finansiella tjänster efter tycke och smak. Denna kandidatuppsats syftar till att öka förståelsen för hur etablerade banker och finansbolagförhåller sig till möjligheterna och utmaningarna med att anpassa sina verksamheter i enlighetmed PSD2. Därtill är syftet att undersöka huruvida alternativet att inte ta upp kampen med nyaaktörer om de kundnära tjänsterna är en möjlig överlevnadsstrategi för de etablerade aktörerna.Den kvalitativa studien som ligger till grund för slutsatserna bygger på intervjuer somgenomförts med respondenter från två etablerade aktörer samt en ny aktör på den svenskabankmarknaden. Principerna för kvalitativ innehållsanalys har tillämpats vid strukturering ochanalys av intervjuerna. Resultatet visar att PSD2 även förväntas ge etablerade aktörer nya möjligheter attvidareutveckla sina tjänster genom att använda det tekniska ramverket utöver de regulatoriskakrav som direktivet föreskriver. I valet av strategi för PSD2 och de möjliga roller i värdekedjansom erbjuds finns det dock utmaningar med både den mest tillbakalutade och framåtriktademarknadspositionen eftersom dessa ställer krav som är svåra att leva upp till. PSD2 kommeräven medföra fler samarbeten mellan etablerade och nya aktörer som följd av att det finns ettömsesidigt beroende mellan parterna i ambitionen om att leverera den bästa kundupplevelsen.

Denna studie undersöker hur kunskap om användarmotivation kan vara ett stöd för UX-design vid utformningen av online-samhällen för kartdatadelning. Studien är en fallstudie och baseras på undersökningen av att potentiellt använda sig av Open source map som grundkarta för cykelvägsapplikationen Cykelstaden som förvaltas av Trafikkontoret i Göteborg. Studien genomfördes genom en enkätundersökning, intervjuer med en kartograf och användare som nyttjar både Cykelstaden och olika kartdatadelningstjänster. Studiens delmål var även att undersöka vilken kontextuell information som önskas i ny och framtida användning av digital kartografi. Resultaten visar delvis på att användare utrryckligen vill vara delaktiga vid utformningen och utvecklingen av digitala tjänster. Korrelationen med studiens teoretiska implikationer visar att studier av användarmotivationer inför användningen av digital kartografi leder till att tjänsterna används och har för användare nytta. Resultaten pekar således på att kunskap om användarnas motivationsfaktorer och vad de drivs av vid användningen av digitala tjänster är en viktig framgångsfaktor för framtida digital utveckling av kartdatatjänster. Användarnas vilja och intresse för användarmedverkan kan således hjälpa till att bana vägen för en mer accepterad och tillämpad UX-design.Studenten påbörjade examensarbetet vt 2017 och slutförde arbetet vt 2018.

Full textAbstract:
Background: There is earlier research in the field of recovery and from a patient perspective. However, it is relatively unexplored if you look within the specific group of patients who suffers from a psychotic disease, and in a context of what support the patient desire from the nurse in the open psychiatric care unit. Aim: To describe what type of support patient with psychotic disease would like from the nurse, in the open psychiatric care unit. Method: The study´s methodology is qualitative and inductive. The study is built on five interviews from patients in a psychiatric open care unit who suffers from psychotic diseases. The interviews have been analysed based on qualitative content analysis. Result: The result indicates that the patients express a desire that the nurse supports them in four areas to focus on health, to get support with its problems, to be able to tell and someone listens and through time given, be able to get to know the nurse, which is the foundation of comfort and stability. Conclusion: The result responds to the purpose of the study, and the result also reveals that it's a difference in what support´s requested between de two groups of patients, one with the severe mental illness and the other who´s studied -patients who suffers from psychotic disease. The conclusion is made by compare the earlier research with the result from this study.Bakgrund: Det finns tidigare forskning inom området återhämtning och ur ett patientperspektiv. Det är däremot relativt outforskat om fokus riktas mot gruppen psykossjuka och i en kontext av vad de önskar för stöd av just sjuksköterskan inom ramen för den öppna psykiatrin. Syfte: Att beskriva vad patienter med psykossjukdom i den psykiatriska öppenvården önskar för stöd av sjuksköterskan i sin återhämtning. Metod: Studie bygger på fem intervjuade patienter som har kontakt med ett psykiatriskt öppenvårdsteam specialiserat på psykossjukdomar. Studien genomfördes med en induktiv ansats. Insamlade data analyserades utifrån kvalitativ innehållsanalys. Resultat: Det framkommer att patienterna uttrycker en önskan om att sjuksköterskan ger stöd inom fyra huvudområden; att ha fokus på det friska, att få stöd med sina problem, att få berätta för någon som vill lyssna och att få tid att lära känna sjuksköterskan är grunden till en trygg och god relation. Slutsatser: Resultatet svarar på studiens syfte, utifrån resultatet i förhållande till tidigare forskning kan också slutsatsen dras att det är skillnad i vilket stöd som efterfrågas mellan gruppen ”svårt psykiskt sjuka”, som bakgrunden i huvudsak utgörs av, mot gruppen av psykossjuka personer.

Full textAbstract:
Bakgrund: Startupföretag bidrar i dagens samhälle med flertalet innovationer, vilket storföretag kan ta del av genom öppen innovation. När företagen samarbetar med varandra kan parterna tillsammans främja innovation och ta del av ny kunskap. Startupföretag får hjälp med kommersialisering av affärsidén och storföretag kan behålla sin marknadsposition genom användningen av ny teknik. På grund av den stora asymmetrin organisationerna emellan är det av intresse att ge en förklaring för vad som påverkar en affär mellan startupföretag och storföretag, för att möjliggöra fler lyckade samarbeten. Syfte: Syftet med studien är att utifrån startupföretags perspektiv undersöka faktorer som påverkar en lyckad affär mellan startupföretag och storföretag inom högteknologiska branscher. Metod: Studien utfördes med en kvantitativ metod där empirin samlats in med hjälp av enkäter via en tvärsnittsdesign. Vidare har studien utgått från det positivistiska perspektivet där en deduktiv ansats använts. En hierarkisk logistisk regressionsanalys genomfördes för att analysera hur tidigare erfarenhet av storföretag, matchad via stödfunktion, avtalsdesign, förtroende, kommunikation, indirekta värden och direkta värden samvarierar med en lyckad affär mellan storföretag och startupföretag. Slutsats: Studiens resultat visar att ökad omsättning, avtalsdesign, tidigare erfarenhet av kontraktering, stödfunktioner, kostnadseffektivitet och indirekta värden har ett statistiskt signifikant samband med lyckad affär. Ökad omsättning, ett detaljerat avtal, tidigare erfarenhet av kontraktering och matchning via stödfunktion ökar sannolikheten för en lyckad affär. När vikt läggs vid kostnadseffektivitet och indirekta värden minskar sannolikheten att affären blir lyckad. Genom att ta studiens faktorer i beaktning kan både startupföretag och storföretag öka sannolikheten att det blir en lyckad affär.Background: Startups contribute in today's society with multiple innovations, which large companies can take part of through open innovation. By collaborating, both companies can enhance innovation and take part of new knowledge. Startups receive help with the commercialization of their business idea and large companies can keep their market position through the use of new technology. Due to the large asymmetry between the organisations, it is of interest to create a broader explanation of what affects the deal between startups and large companies, in order to enable more successful collaboration. Purpose: The purpose of the study is to examine different factors that affect a successful deal between startups and large companies in high-tech industries from the startup perspective. Methodology: The study used a quantitative research method where the empirical data has been collected by questionnaires. The study is based on a positivist philosophical standpoint with a deductive approach. A hierarchical logistic regression analysis was performed to analyze how the factors previous experience with large companies, matched by a support function, contract design, trust, personal chemistry, communication, indirect values and direct values affects the deal between large companies and startups. Analysis and conclusion: The result of the study shows that increased revenue, contract design, previous experience of contracting, support functions, cost efficiency and indirect values have a statistically significant correlation with a successful deal. Increased revenue, a detailed contract, previous experience of contracting and matched by a support function increases the probability to perform a successful deal. When focus shifts to cost efficiency and indirect values, the probability of the deal being successful decreases. By taking the factors into account, both startups and large companies can increase the probability that it will be a successful deal.

Full textAbstract:
The VAT treatment of over-allowances in the motor retail industry has proved contentious for South African Revenue Services (“SARS”). VAT legislation dictates that notional VAT may be claimed on the lower of the open market value and the consideration paid. The industry, however, claims notional VAT on the actual consideration paid for a used vehicle on the basis that a higher output VAT will be declared on the consequent sale of the new vehicle. This is because the over-allowance is offset against the lower discount granted. SARS allows this practice on account of SARS’ own issuance of a binding general ruling, provided certain criteria are met. This ruling is contained in the VAT Guide to Motor Dealers. This study performs an analysis of the current practice by South African motor retailers pertaining to over-allowances. The aim of the study is to determine the impact on the industry of the issuance of the Guide, both practically and from the perspective of compliance, focussing on VAT legislation and Competition Commission legislation. The study discusses the requirements contained in the Guide in the light of the Competitions Act and the practical benefits, and concludes that the industry is satisfied with the issuance of the Guide, despite its silence on the interpretation of certain key criteria. The industry has chosen to assume that, as SARS has acted reasonably in the issuance of the Guide, it would not expect the industry to deviate from any other legislation, including the Competitions Act. If SARS is not satisfied with this interpretation, the Guide will have to be amended to include definitions of terms such as “permissible discount”. AFRIKAANS : Die hantering van die toelating van oormatige BTW in die motorvoertuig-kleinhandelsindustrie is, insover dit die Suid-Afrikaanse Inkomstediens (“SAID”) betref, omstrede. BTW-wetgewing bepaal dat geagte BTW gehef mag word op die laagste van ope markwaarde en die werklike bedrag betaal. In die motorvoertuigindustrie word BTW egter altyd gehef op die werklike bedrag betaal vir ‘n gebruikte voertuig met die veronderstelling dat hoër uitset BTW verklaar gaan word met die verkoop van ‘n nuwe voertuig wat die inruiltransaksie tot gevolg gaan hê. Daar word geredeneer dat die oortoelating van BTW uitgekanselleer gaan word deur ‘n laer afslag op die nuwe verkope. As gevolg van bindende bepalings in die BTW Handleiding vir Motorhandelaars, wat uitgereik is deur die SAID en die nakoming van sekere voorwaardes deur die motorhandelaars, laat die SAID hierdie praktyk toe. In hierdie mini-verhandeling word die vereistes wat in die Handleiding vervat is teen die agtergrond van die Wet op Mededinging en die praktiese voordele daarvan bespreek. Die gevolgtrekking is dat die motorvoertuigindustrie tevrede is met die uitreiking van die Handleiding vir motorhandelaars ongeag die feit dat sekere sleutel aspekte nie in die Handleiding voldoende toegelig word nie. Die motorindustrie het die aanname gemaak dat SAID redelikerwys opgetree het deur die Handleiding uit te reik en sal daarom nie verwag dat die industrie van enige ander wetgewing sal afwyk nie, insluitende die Wet op Mededinging. As die SAID nie tevrede is met hierdie interpretasie nie sal dit beteken dat die Handleiding aangepas sal moet word om ander relevante terminologieë soos “toelaatbare afslag” beter te omskryf en te verduidelik.

This thesis estimates the effects of monetary policy shocks by employing vector
auto regressions (VAR). I argue that to the extent the central bank and the private sector
have information not reflected in the VAR, the measurement of policy innovations
is contaminated. These incorrectly estimated policy shocks then generate misleading
results about the effects of monetary policy. This thesis first attempts to figure out
the variables indeed observed by central banks to make monetary policy decisions and
then formulates the monetary policy reaction function by using those variables. Having
identified more realistic monetary policy functions in VAR models, I conclude that
most of the previous puzzling results about the effect of monetary policy shocks might
be due to incorrectly identifying the monetary policy reaction function.Thesis (Ph.D, Economics) -- Queen's University, 2009-06-15 15:59:13.04

Distance education as delivery mode is currently attracting more and more learners globally
who want to improve their skills and qualifications. This is necessitated by especially the
limited components of existing contact universities, financial expenditure and working
learners. The presenting of open distance learning by existing contact universities in South
Africa is relatively unknown. Consequently the aim of this study is also to investigate a
model for Open Distance Learning used at the NWU, an existing contact university. In order
to achieve this aim, several other aims were set as well. The most important findings of these
aims are subsequently summarized.
Aim one was to determine how distance education, open distance learning and e-learning
have been conceptualized in the literature. It emerges clearly from the literature that various
barriers and challenges accompany the implementation and delivery of distance and open
distance learning program. These barriers particularly concern matters such as academic,
cultural and technical aspects like the student’s experience, the position of the lecturer
regarding the program, the design of the program, the fact that development in technology is
constantly kept in mind and kept up with, as well as problems with financial aspects.
The second aim intended to compare open distance learning in developed and developing
countries as far as contact classes and e-learning are concerned, in order to establish the best
practices for a suitable management model. The open distance learning models of twelve
universities were examined separately and compared to one another. From these comparisons
the following components of open distance learning were indentified which would be
applicable to both developing and developed countries: (i) the use of traditional paper-based
study material; (ii) the use of various forms of technology; (iii) the use of e-learning, and (iv)
voluntary supporting contact classes. From the literature it has been shown that, despite
limited infrastructure, poverty, illiteracy and geographical isolation, e-learning and m-learning are increasingly implemented as delivery modes in open distance learning programmes in
developing as well as developed countries.
Aim three was to establish, from within the literature, the nature of management models with
specific reference to the innovations within managing business models in the context of open
distance learning. Firstly variables which play a role in new business models were
considered. Secondly the levels according to which the innovation of new models should take
place were investigated, and also how these could possibly be implemented within the NWU,
as well as the principles applicable to the innovation and implementing of a new model from
an existing mother company. Factors which could play a part in the plans to present distance
learning programs were also considered, whether these would imply a new distance education
unit or the continued presentation of such programs. The most important aspects to consider
for such a management model are addressed in aim seven.
Aim four investigated the effect of attendance or non-attendance of contact classes on the
academic achievement of open distance learning students within selected Advanced
\certificate in Education (ACE) programs. This aim referred to an empirical investigation
which comprised five phases. A consecutively progressing research design was used,
consisting of both quantitative and qualitative methods, known as the multi-mode design.
Phases one to three address aim four. Spearman’s rank order correlations, one-way ANOVAs
(t-tests) and two-way tables (Cramer’s effect sizes) were calculated in order to identify
significant correlation (effect sizes) between variables. It was found that students who
attended contact classes did not achieve significantly better during examinations than students
who did not attend. The average module mark in the examination of students who did not
attend contact classes was 49.5%. The average mark of students who attended three or more
contact classes was 52.6%. Considering the examination results, the passing rate of students
who attended contact classes was 89% as opposed to 82% for those who did not attend any
contact classes. Upon comparing data of students attending vacation school and those who did
not, it emerged that students who attended vacation school achieved an average module mark
(for all modules) of 42.4% as opposed to 52.7% of those who did not attend any vacation
school.
Aim five considered the open distance learning student’s opinions on and experience of
attending contact classes and not attending, within selected ACE programs. Questionnaires
were distributed to a number of students who attended contact classes, and to some who did not attend. The following findings emerged: reasons why students do not attend contact
classes are (i) distance from tuition centre; (ii) personal reasons such as family responsibilities
or funerals; (iii) because classes are not presented by full-time NWU lecturers; (iv) medium of
instruction, limited time and class sizes also seemed to pose problems.
Aim six investigated the readiness of the open distance learning student for e-learning within
selected ACE programs. Focus group interviews regarding this aim were conducted with three
groups of students. The following was found: (i) the vast majority of students (62.1%) do not
have computers at home; (ii) 80.4% indicated that that they could not access the Internet, and
that (iii) cell phone communication seemed to be the solution, since 93.1% of students own
cell phones.
Aim seven investigated the opinions of management experts at the NWU concerning the
components and practice of an ODL model at the NWU. In order to comply with this aim, an
intensive literature study was done on open distance learning models internationally. In the
second place an empirical investigation was conducted regarding attendance of contact classes
and e-learning as teaching method for the teaching and learning component of an open
distance learning model. Thirdly focus group interviews were conducted with senior
management of the NWU regarding challenges, risks and components of an open distance
learning model. According to the data obtained from these interviews, various matrix analyses
were done, which could serve as basis for a management model in open distance learning. The
matrix analyses identified the following eleven components as important for a management
and practice model for open distance learning: (i) Teaching and learning pertaining to
development and quality of study material, effective assessment, the required program
designers, training of lecturers and facilitators for presenting open distance learning programs,
and efficient quality evaluation. (ii) ITC for open distance learning refers to technological
support for processes such as assessment, interactive presentation of lessons, using Internet,
cell phone technology and the use of the web page. (iii) Support practice for management
which involves matters such as the policy of administrative processes regarding registration,
cooperation with consortiums, assessment of assignments and examinations, and dealing with
administrative processes different from on-campus.
(iv) Finances which refer to compiling annual budgets, remuneration of facilitators,
determining the profitability of programs presented, as well as financing technological
development. (v) Tuition centres: coordination between the university and tuition centres is crucial as far as contact classes, interactive presentations, group discussions as well as
examinations are concerned. (vi) Short courses and projects, especially as far as continuing
professional development is concerned, as well as the development of a preparatory college
for prospective students and cooperation with private institutions. (vii) Quality processes
which include compulsory evaluation of program content and of the effect of programs as
evaluated by the private sector, identifying new programs and cooperation with other
faculties. (viii) Marketing which can be done by the university itself or by a consortium of
collaborators. (ix) A structure for open distance learning with its own, unique and particular
structure according to need. Factors which may be significant are the number of students
studying through open distance learning, the nature of the programs presented and
cooperation between consortiums. (x) Hierarchical structure which in the first place requires
effective management of an open distance unit, and secondly also that such unit functions in
cooperation with and within existing structures. Especially executive authority and lines for
reporting should be outlined clearly. (xi) Research must be done in collaboration with other
faculties in order to acquire a particular distance education entity. Research regarding the
management of, e.g. the effect of programs, contact class attendance, readiness for e-learning
and technology at tuition centres, can also be conducted.
The exigency for development of an o pen distance learning unit within the NWU, together
with a management model for effective management and practice of distance programs, was
the main theme of this study. This study has succeeded in suggesting a management model
which could be utilized profitably in endeavoring to attain the strategic aim of presenting
programs by means of distance education. It also addresses the national need in South Africa
of access to tertiary education for more learners.PhD (Education Management), North-West University, Potchefstroom Campus, 2012

AFRIKAANS: Enkele tegniese skeppinge wat die Tsongavrou in die tradisionele lewenswyse vervaardig en wat prominent by die Tsongakraal-Opelugmuseum in die Hans Merensky-Natuurreservaat gedemonstreer word, is as studiemateriaal geselekteer. Weens die museologiese vereiste en noodsaaklikheid van goedgedokumenteerde voorwerpe is pottebakkery, soutontginning en kralewerk deeglik volgens vorm, funksie en vervaardigingswyse binne die museum sowel as in Gazankulu, tuiste van die Tsongavrou, nagevors. Dit is ook volkekundig binne funksionele kultuurverband behandel. Historiese gebeurtenisse is nagegaan wat die Tsonga van die huidige Gazankulu met die Tsonga van Mosambiek, hul oorspronklike tuiste vir baie eeue, verbind. Ook die kulturele lewe van die mense van wie in hierdie studie sprake is, is kortliks geskets. Beperkinge wat die museumopset op 'n lewensgetroue weergawe van 'n volk meebring, en die mate van kunsmatigheid wat wel voorkom, is kortliks bespreek. Pottebakkery by die Tsonga, alhoewel deur die omliggende stamme beïnvloed, toon 'n eie karakter, veral as daar meer gekonsentreer word op die oorspronklike Tsonga-keramiekware wat tot in Mosambiek nagevors kon word. Vervaardiging kom nie meer so algemeen voor nie, maar benutting is meer verspreid. 'n Hele stel potte wat kookpotte, bier- en waterpotte, eetbakke, waskomme en maalbakke insluit, word volgens vorm, funksie, voorkoms en vervaardigingswyse bespreek. Soutvervaardiging tref ons by die Tsonga aan, omdat daar 'n paar southoudende minerale warmwaterbronne in Gazankulu voorkom. Argeologiese en etnologiese gegewens dui daarop dat hierdie ontginningsproses alreeds vir die afgelope 1800 jaar bedryf word. Handel is met sout gedryf en hierdie sout is gesog, omdat magies-religieuse eienskappe daaraan toegeskryf word. Die Tsonga was die soutvervaardigers ten minste gedurende die afgelope 100 jaar. Die Tsonga beskik oor hul eiesoortige kralewerk wat as bykomstige versiering gedra word. Veral tydens feestelikhede word hierdie kleurvolle kralesierade vertoon. 'n Kralewerk-klassifikasie kon volgens voorkoms, funksie en vervaardigingswyse saamgestel word. Hierdie bedryf kan, as 'n aspek van die tegniese skeppinge van die Tsongavrou, met welslae in die opelugmuseum uitgebeeld en uitgebrei word. Daar is tot die gevolgtrekking gekom dat die Tsongakraal-Opelugmuseum definitief bestaansreg het, omdat die Tsonga 'n eiesoortige kultuurlewe openbaar. Met 'n weldeurdagte en goedbestuurde uitstallings-, vervaardigings-, en verkoopsaksie het hierdie opelugmuseum besliste uitbreidingsmoontlikhede en kan die bestaande funksies van versameling, bewaring en opvoeding deur middel van programme en uitstallings nog beter tot hul reg kom. Band II bestaan uit 'n fotodokumentasie wat die teks oor die vervaardigingswyse van tegniese skeppinge aanvul. Bylaes wat handel oor die vervaardigingswyse van tegniese skeppinge, Tsongabotanie, 'n Tsongawoordelys oor tegniese skeppings wat in hierdie studie genoem word, asook aanvullende historiese inligting en liggingskaarte word aangeheg. ENGLISH: A description is given of some aspects of the material culture of the Tsonga women of Gazankulu as demonstrated at the Tsongakraal Open-air Museum in the Hans Merensky Nature Reserve. Pottery, headwork and the salt extraction process have been described museologically according to form, function and the process of manufacture. Anthropologically the functional approach to culture has been followed. A short historic and cultural survey has been given of the Tsonga people who first lived in Mozambique, their role as traders over the centuries on the old trade routes through Gazankulu and their reason for settlement in present Gazankulu. The restrictions and superficiality in portraying a way of life within the museum has been discussed in short. Pottery has been influenced by the surrounding tribes, but a specific Tsonga pottery tradition has been identified, leading back to Mozambique. Although there seems to be a decline in the manufacture of pots, a whole range of ceramic ware which includes cooking pots, beer and water pots and bowls could be described according to form, function, manufacturing process and decorative patterns. Archaeological and ethnological references to the 1800 year old salt extraction industry from salt pans near mineral springs in Gazankulu, assisted in the reconstruction of the whole process with its uses and magico-religious properties. The Tsonga were the salt producers for at least the last one hundred years. Headwork as adornment features prominently amongst Tsonga women, especially during festivals. A classification system of all the headwork has been compiled and described according to appearance, function and manufacture. The manufacturing of headwork can be introduced as a further aspect of material culture in the open-air museum. The study concludes that the distinguishing material culture of the Tsonga gives purpose to the existence of the Tsongakraal Open-air Museum. With creativity and a well-planned management programme, the museological functions of collection, preservation and education (recreational programmes and displays) of this museum can be extended. Annexures include a detailed photographic record of the manufacturing of items of material culture, the ethno-botany of the Tsonga, a list of Tsonga cultural terms as well as maps and historical information.Dissertation (MA)--University of Pretoria, 2013.

Full textAbstract:
Thorough investigation of the glycine conjugation pathway has been neglected over the last 30 years. Environmental factors, nutrition, and the chronic use of medications are increasing the exposure of humans to benzoate and drugs that are metabolized to acyl-CoA intermediates. Glycine conjugation of mitochondrial acyl-CoAs, catalysed by glycine N-acyltransferase (GLYAT, E.C. 2.3.1.13), is an important metabolic pathway responsible for maintaining adequate levels of free coenzyme A (CoASH). However, because of the small number of pharmaceutical drugs that are conjugated to glycine, the pathway has not yet been characterised in detail. Therefore, one of the objectives of this thesis was to develop a better understanding of glycine conjugation and its role in metabolism. In humans and animals a number of endogenous and xenobiotic organic acids are conjugated to glycine. Glycine conjugation has generally been assumed to be a detoxification mechanism, increasing the water solubility of organic acids in order to facilitate urinary excretion. However, recently it was proposed that the role of the amino acid conjugations, including glycine conjugation, is to regulate systemic levels of amino acids that are also utilised as neurotransmitters in the central nervous systems of animals. The glycine deportation hypothesis was based on the observation that, compared to glucuronidation, glycine conjugation does not significantly increase the water solubility of aromatic acids. A thorough review of the literature for this thesis showed that the major role of glycine conjugation, however, is to dispose of the end products of phenylpropionate metabolism. The review also introduced the new perspective that mitochondrial glycine conjugation prevents the accumulation of benzoate in the mitochondrial matrix by forming hippuric acid a less lipophilic conjugate that can be more readily transported out of the mitochondria. Although organic anion transporters can export benzoate from the matrix, this process would likely be futile because benzoic acid can simply diffuse back into the matrix. Hippurate, however, is significantly less lipophilic and therefore less capable of diffusing into the matrix. It is therefore not the transport out of the mitochondrial matrix that is facilitated by glycine conjugation, but rather the ability of the glycine conjugates to re-enter the matrix that is decreased. Lastly, glycine conjugation of benzoate also exacerbates the dietary deficiency of glycine in humans. Because the resulting shortage of glycine can negatively influence brain neurochemistry and the synthesis of collagen, nucleic acids, porphyrins, and other important metabolites, the risks of using benzoate as a preservative should not be underestimated.
To date, no defect of the glycine conjugation pathway has been reported and this, together with the fact that GLYAT plays an important role in hepatic metabolism, suggests that this pathway is essential for survival. GLYAT activity affects mitochondrial ATP production, glycine availability, CoASH availability and the toxicity of various organic acids. Therefore, variation in the glycine conjugation pathway could influence liver cancer, musculoskeletal development and mitochondrial energy metabolism. Significant interindividual variation exists in glycine conjugation capacity. The molecular basis for this variability is not known. The main aim of this thesis was to investigate and characterise the genetic variation in the coding region of the GLYAT gene. This was accomplished by firstly, investigating the influence of non-synonymous single nucleotide polymorphisms (SNPs) on the enzyme activity of a recombinant human GLYAT and secondly, by analysing the level of genetic
variation in the coding region of the GLYAT gene using existing worldwide population data. To investigate the influence of non-synonymous SNPs in the GLYAT gene on the enzyme activity, a recombinant human GLYAT was prepared, and characterised. Site-directed mutagenesis was used to generate six variants of the enzyme (K16N; S17T; R131H; N156S; F168L; R199C). The variants were expressed, purified, and enzymatically characterised. The enzyme activities of the K16N, S17T and R131H variants were similar to that of the wild-type, whereas the N156S variant was more active, the F168L variant less active, and the R199C variant was inactive. The results showed that SNP variations in the human GLYAT gene can influence the kinetic properties of the enzyme. The genetic variation data of the human GLYAT open reading frame (ORF) available on public databases was investigated by formulating the hypothesis that due to the essential nature of the glycine conjugation pathway, the genetic variation in the ORF of the GLYAT gene should be low and that deleterious alleles will be found at low frequencies. Data from the i) 1000 Genome Project, ii) the HapMap Project, and iii) the Khoi-San/Bantu Sequencing Project was downloaded from available databases. Sequence data of the coding region of a small cohort of South African Afrikaner Caucasian individuals was also generated and included in the analyses. In the GLYAT ORF of the 1537 individuals analysed, only two haplotypes (S156 and T17S156) out of 14 haplotypes were identified in all populations as having the highest haplotype frequencies (70% and 20% respectively). The S156C199 and S156H131 haplotypes, which have a deleterious effect on the enzyme activity of a recombinant human GLYAT, were detected at very low frequencies. The results of this study indicated that the GLYAT ORF is remarkably conserved, which supports the hypothesis that the glycine conjugation pathway is an essential detoxification pathway. The findings presented in this thesis highlight the importance that future investigations should determine the in vivo capacity of the glycine conjugation pathway for the detoxification of benzoate and other xenobiotics.PhD (Biochemistry), North-West University, Potchefstroom Campus, 2015

Two groups of progeny trials China-fir populations are used for study age-age phenotypic correlation in this thesis. Both of them are single tree family from a same clonal seed orchard which composed of 25 clones established in 1972 in the central mountain area of Taiwan. The elder progeny test population, A, is composed of 232 trees from 18 maternal families which grown in wild field; the juvenile population, B, is composed of 15,000 seedlings from all the 25 families, grown in nursery garden, this study use only 1,500 seedlings for analysis. The A population are measured in 2, 6, and 25 years for height, diameter breast height and volume as well as annual height growth between age intervals, 27 years wood density is also involved; for B population, the acquired traits are root diameter, root length, fresh and dry biomass, height and ratio of shoot-root biomass as well as sturdiness quotient and Dickson quality index from 5, 7, 9, 13 months seedlings. Results show that both population in field and greenhouse have very high individual heritability for most of the traits (h2=0.35~0.62 and 0.25~1 respectively), and among all the family appear significant variance. Core finding on the correlation demonstrate that self-correlation within population A has strong trait-trait correlation (r=0.61~0.97, P<.0001) in 25 years, and age-age correlation within A exist higher relationship between shorter age intervals (2 & 6 years: r= 0.5, P<.0001; 6 & 25 years: r=0.4, P<.0001). The age-age correlations between two populations reveal that most of the traits in seedling age 5, 7, 9 months have correlations with height and volume in 25 years group (│r│= 0.4~0.7), which indicate that China-fir juvenile traits can serve as indicators for the early selection in a very early growing period.

Professional development (PD) of teachers is part of the Department of Basic Education‘s (DBE)
initiative to encourage school communities to use of information and communication technology (ICT)
to improve the quality of Mathematics teaching and learning. The South African Council of Educators
stipulates that PD programmes should align with system-wide needs, strengthen learning area content
and outcomes, and promote system transformation. Imbedded in this system-wide criterion is The
White Paper on e-Education to employ a fully ICT integrated system at all levels of education:
management, teaching and learning, and administration by 2013. Mathematics teachers require PD
that develops their technological pedagogical and content knowledge (TPACK) and their social
professional identity (SPI). The PD of Mathematics teachers for ICT integration can assist the DBE to
achieve the aims of The White Paper on e-Education and bridge the technology gap between South
Africa and international education systems. Open distance learning (ODL) could be a viable method
to deliver PD to Mathematics teachers to address their zone of proximal development, develop their
TPACK, and establish and maintain their SPI. This study made use of a fully mixed sequential equal
status multi-mode research design and methodologies to develop guidelines for the PD of
Mathematics teachers in the pedagogical use of ICT in ODL. The qualitative phase (Phase I) was
rooted in the interpretivist paradigm. Through an adjustable exploration of a systematic literature
review, the researcher identified 23 core documents, analysed them with Atlas.ti™, and
conceptualised four themes according to Engeström‘s third generation activity theory (AT). Phase II
(radical exploration phase) of the research design was rooted in the radical structuralist paradigm. In
the context of transformation, it developed, validated, and standardised a research instrument for the
measurement of Mathematics teachers‘ PD requirements. The instrument was distributed to 300
senior phase (grades 7-9) Mathematics teachers in eight education management district centres of the
WCED. The analyses of the quantitative data conceptualised a fifth activity system. The five activity
systems from the adjustable and radical exploration phases were symbiotic, and co-dependent.
Expansive learning was used for boundary crossing and network building during six phases of this
study. The findings from the six phases of the expansive learning cycle indicated that PD of
Mathematics teachers in ODL for Phase III implementation of the e-Education policy should be a joint
initiative. Fundamentally ICT integration and implementation should start with Department of Basic
Education (DBE) initiatives. The DBE and Provincial Departments of Education (PDEs) should
conduct a needs analysis of ICT implementation, evaluate previous ICT PD programmes, plan ICT PD
strategies aligned with the ICT development plan, as well as with the requirements of the Mathematics
teachers. The DBE and PDE should invest in the provision of ICT equipment, afford human capital,
reinstate the laptop initiative for teachers, and supply schools with networked-computer facilities to
explore online platforms for PD. Mathematics teachers should assess their professional knowledge to
construct new philosophies, create a subject network group, and interact as participants and members
within their social environments. The standardised instrument could be used to determine and
compare the PD of Mathematics teachers in other provinces and contexts.PhD (Training and development), North-West University, Potchefstroom Campus, 2014

Abstract in English, Tswana and AfrikaansPeople who graduated from higher education, whether they attended classes on campus or studied via a distance mode of learning, have not only been educated but are also able to participate in and contribute positively to the political, social and economic forums in their immediate environments and within their country. Progressing through the higher education system successfully is not easy since there are many challenges to overcome. Students With Disabilities (SWD) face even greater challenges in making their way through the system to emerge triumphantly as graduates. Institutions of higher learning, including Open Distance eLearning (ODeL) facilities, must provide support to SWD in order to facilitate their learning experience so that they are better equipped to succeed. Therefore, it is vital to promote access to higher education for people with disabilities and to provide support, such as making assistive technologies and human services available, for SWD within ODeL institutions. This qualitative study was exploratory in nature and used a multiple case study research design in the chosen area to investigate the provision of support for SWD in the ODeL institution. Data were collected by means of semi-structured interviews and a document analysis, and these two methods of data gathering assisted with triangulation. The research findings revealed differences between the findings that were obtained through the responses received from teacher and staff member participants. The research findings also revealed differences between the findings that were obtained through the responses received from the participants, in general, and those obtained through the document analysis. The findings obtained through responses received from teacher participants showed that support for SWD was more evident at the school level than at the ODeL institution, that is, at the tertiary level of education. The document analysis of the policies of the ODeL institution revealed that the policies were general and did not specifically relate to the needs of SWD. At the same time, the findings in this dissertation of limited scope showed that the use of technology and the availability of assistive devices were more prominent at the school level than at the ODeL institution.

Mense wat aan hoëronderwysinstellings gradueer, of hulle klasse op kampus bygewoon het of deur 'n afstandsmetode van leer studeer het, is nie slegs onderrig nie, maar hulle kan ook deelneem aan en positief bydra tot die politieke, sosiale en ekonomiese forums in hul onmiddellike omgewing en in hul land. Dit is nie maklik om suksesvol deur die hoëronderwysstelsel te vorder nie, omdat daar baie struikelblokke is om te oorkom. Studente met gestremdhede (SMG) het selfs meer uitdagings om hul weg deur die stelsel te baan en triomfantlik as graduandi te verrys. Hoëronderriginstellings, insluitende oop e-afstandsleer (ODeL) -fasiliteite, moet ondersteuning aan SMG bied om hul leerervarings te fasiliteer sodat hulle beter toegerus is om sukses te behaal. Dit is daarom noodsaaklik om toegang tot hoër onderwys en ondersteuning aan mense met gestremdhede te bied, soos om hulptegnologieë en menslike dienste aan SMG in ODeL-instellings beskikbaar te stel. Hierdie kwalitatiewe studie was verkennend van aard en het 'n veelvoudige gevallestudie-ontwerp in die gekose veld gebruik om die voorsiening van ondersteuning aan SMG in 'n ODeL-instelling te ondersoek. Data is versamel deur semigestruktureerde onderhoude en 'n dokumentonleding; hierdie twee metodes van dataversameling het met triangulasie gehelp. Navorsingsbevindings het verskille aangedui tussen die data wat verkry is van die onderwyser en die van deelnemende personeellede se reaksies. Navorsingsbevindings het ook verskille aangedui tussen die data wat verkry is van deelnemers se reaksies oor die algemeen en die wat deur dokumentontleding verkry is. Die bevindings wat deur die onderwyserdeelnemers verkry is, het aangedui dat ondersteuning aan SMG duideliker op skoolvlak was as by die ODeL-instelling; dit is op tersiêre vlak van onderwys. Die dokumentontleding van die ODeL-instelling se beleide het aangedui dat die beleide algemeen was nie spesifiek met SWD se behoeftes verband hou nie. Terselfdertyd het die bevindings van hierdie verhandeling van beperkte omvang getoon dat die gebruik van tegnologie en die beskikbaarheid van hulptoestelle meer prominent was op skoolvlak as by die ODeL-instelling.

Este trabalho tem por objectivo analisar o impacto da política monetária numa
pequena economia aberta, como a de Cabo Verde. Uma vez que, como foi dito, a
política monetária actualmente é essencial para a condução de uma política antiinflacionista,
constatou-se que durante o período em estudo (1975-2008), a estabilidade
de preços tem sido um dos objectivos principais das autoridades cabo-verdianas. Este
tem procurado através de um Acordo de Stand-by com o FMI, restaurar o equilíbrio das
contas públicas nacionais. Sendo assim comecei por efectuar uma breve caracterização
da economia de Cabo Verde. Nesta linha, também foi analisado o contributo da
conciliação entre as políticas monetária, cambial e orçamental para o crescimento
harmonizado da economia. Seguidamente efectuou-se um estudo sobre os mecanismos
de transmissão da política monetária, de forma a determinar o impacto de uma mudança
da taxa de juro no PIB e noutras variáveis, tendo-se utilizado para tal um modelo VAR.Monetary policy is a branch of economic policy is currently very relevant to the conduct of an anti-inflationary policy. The conduct of sound monetary policy has been a major concern in many countries, developed and developing countries, including Cape Verde. This paper aims to analyze the impact of monetary policy in a small open economy, such as Cape Verde. Since, as mentioned above, monetary policy is now essential to the conduct of an anti-inflation policy, it was found that during the study period (1975-2008), price stability has been one of the main objectives of Cape Verdean authorities. This has been seeking an agreement through the Stand-by with the IMF, to restore the balance of national public accounts. So I started by making a brief characterization of the economy of Cape Verde. In this line, was also analyzed the contribution of the reconciliation of the monetary, fiscal and exchange rate for the harmonized growth of the economy. Then carried out a study on the transmission mechanism of monetary policy in order to determine the impact of a change in the rate of GDP and other variables, having been used for such a VAR model.

Full textAbstract:
For the knowledge economy of the twenty-first century, intellectual skills (such as critical thinking) have been identified as imperative for success. Educational institutions have a responsibility to equip students with the knowledge and skills required for future employment. The South African Institute of Chartered Accountants has identified critical thinking as one of the skills that should be developed in Financial Accounting students who wish to become chartered accountants.
For this limited-scope dissertation a qualitative study was done, applying a constructivist paradigm to a case study design, to explore the development of critical thinking in first-year Financial Accounting students in an open distance and e-learning context in South Africa. To achieve this, data were collected through semi-structured interviews with twelve academics and the use of document analysis.
As the focus of the study was limited to two first-year financial accounting modules which form part of the South African Institute of Chartered Accountants accredited programme taught at an open distance and e-learning institution, the findings cannot be generalised. While the perceptions of students were not considered in the study, the findings provide valuable insight into the development of critical thinking in accounting modules.
The findings revealed that, although academics believe critical thinking skills and good thinking habits should be developed in first-year Financial Accounting students, it is currently only done through a content-centred approach, or not at all. Furthermore, only technologies which academics are comfortable using, are being incorporated, mainly for the delivery of content. The recommendations made for curriculum evaluation and professional development relate specifically to these findings.Vir die een-en-twintigste-eeuse kennisekonomie is intellektuele vaardighede (soos kritiese denke) geïdentifiseer as noodsaaklik vir sukses. Opvoedkundige instellings het 'n verantwoordelikheid om studente met die kennis en vaardighede toe te rus wat nodig is vir toekomstige indiensneming. Die Suid-Afrikaanse Instituut vir Geoktrooieerde Rekenmeesters het kritiese denke geïdentifiseer as 'n vaardigheid wat studente in Finansiële Rekeningkunde, wat geoktrooieerde rekenmeesters wil word, moet ontwikkel. Vir hierdie verhandeling van beperkte omvang, is 'n kwalitatiewe studie gedoen deur 'n konstruktivistiese paradigma toe te pas op 'n gevallestudie-ontwerp om die ontwikkeling van kritiese denke in eerstejaarstudente in Finansiële Rekeningkunde in 'n oop e-afstandsleerkonteks in Suid-Afrika te ondersoek. Om hierdie doel te bereik, is data versamel deur semi-gestruktureerde onderhoude te voer met twaalf akademici en dokumentontleding te gebruik. Omdat die studie beperk was tot twee eerstejaar finansiële rekeningkunde modules, wat deel vorm van die Suid-Afrikaanse Instituut vir Geoktrooieerde Rekenmeesters se geakkrediteerde program wat by 'n oop e-afstandsleerinstelling aangebied word, kan die bevindinge nie veralgemeen word nie. Alhoewel die studente se persepsies nie in die studie in ag geneem is nie, bied die bevindings waardevolle insig oor die ontwikkeling van kritiese denke in rekeningkundemodules. Die bevindings dui daarop dat, alhoewel akademici glo dat vaardighede in kritiese denke en goeie denkgewoontes in die eerste jaar van Finansiële Rekeningkunde onderrig moet word, word dit tans slegs deur 'n inhoudgebaseerde benadering gedoen, of glad nie. Verder word slegs tegnologieë geïnkorporeer waarmee akademici gemaklik is, hoofsaaklik vir die oordrag van die inhoud. Die aanbevelings vir kurrikulumevaluering en professionele ontwikkeling hou spesifiek verband met hierdie bevindings.

Full textAbstract:
Dans cette thèse, je me suis intéressé aux effets des fluctuations du prix de pétrole sur l'activité macroéconomique selon la cause sous-jacente ces fluctuations. Les modèles économiques utilisés dans cette thèse sont principalement les modèles d'équilibre général dynamique stochastique (de l'anglais Dynamic Stochastic General Equilibrium, DSGE) et les modèles Vecteurs Autorégressifs, VAR.
Plusieurs études ont examiné les effets des fluctuations du prix de pétrole sur les principaux variables macroéconomiques, mais très peu d'entre elles ont fait spécifiquement le lien entre les effets des fluctuations du prix du pétrole et la l'origine de ces fluctuations. Pourtant, il est largement admis dans les études plus récentes que les augmentations du prix du pétrole peuvent avoir des effets très différents en fonction de la cause sous-jacente de cette augmentation. Ma thèse, structurée en trois chapitres, porte une attention particulière aux sources de fluctuations du prix de pétrole et leurs impacts sur l'activité macroéconomique en général, et en particulier sur l'économie du Canada.
Le premier chapitre examine comment les chocs d'offre de pétrole, de demande agrégée, et de demande de précaution de pétrole affectent l'économie du Canada, dans un Modèle d'équilibre Général Dynamique Stochastique estimé. L'estimation est réalisée par la méthode Bayésienne, en utilisant des données trimestrielles canadiennes sur la période 1983Q1 à 2010Q4. Les résultats montrent que les effets dynamiques des fluctuations du prix du pétrole sur les principaux agrégats macro-économiques canadiens varient en fonction de leurs sources. En particulier, une augmentation de 10% du prix réel du pétrole causée par des chocs positifs sur la demande globale étrangère a un effet positif significatif de l'ordre de 0,4% sur le PIB réel du Canada au moment de l'impact et l'effet reste positif sur tous les horizons. En revanche, une augmentation du prix réel du pétrole causée par des chocs négatifs sur l'offre de pétrole ou par des chocs positifs de la demande de pétrole de précaution a un effet négligeable sur le PIB réel du Canada au moment de l'impact, mais provoque une baisse légèrement significative après l'impact. En outre, parmi les chocs pétroliers identifiés, les chocs sur la demande globale étrangère ont été relativement plus important pour expliquer la fluctuation des principaux agrégats macroéconomiques du Canada au cours de la période d'estimation.
Le deuxième chapitre utilise un modèle Structurel VAR en Panel pour examiner les liens entre les chocs de demande et d'offre de pétrole et les ajustements de la demande de travail et des salaires dans les industries manufacturières au Canada. Le modèle est estimé sur des données annuelles désagrégées au niveau industriel sur la période de 1975 à 2008. Les principaux résultats suggèrent qu'un choc positif de demande globale a un effet positif sur la demande de travail et les salaires, à court terme et à long terme. Un choc négatif sur l'offre de pétrole a un effet négatif relativement faible au moment de l'impact, mais l'effet devient positif après la première année. En revanche, un choc positif sur la demande précaution de pétrole a un impact négatif à tous les horizons. Les estimations industrie-par-industrie confirment les précédents résultats en panel. En outre, le papier examine comment les effets des différents chocs pétroliers sur la demande travail et les salaires varient en fonction du degré d'exposition commerciale et de l'intensité en énergie dans la production. Il ressort que les industries fortement exposées au commerce international et les industries fortement intensives en énergie sont plus vulnérables aux fluctuations du prix du pétrole causées par des chocs d'offre de pétrole ou des chocs de demande globale.
Le dernier chapitre examine les implications en terme de bien-être social de l'introduction des inventaires en pétrole sur le marché mondial à l'aide d'un modèle DSGE de trois pays dont deux pays importateurs de pétrole et un pays exportateur de pétrole. Les gains de bien-être sont mesurés par la variation compensatoire de la consommation sous deux règles de politique monétaire. Les principaux résultats montrent que l'introduction des inventaires en pétrole a des effets négatifs sur le bien-être des consommateurs dans chacun des deux pays importateurs de pétrole, alors qu'il a des effets positifs sur le bien-être des consommateurs dans le pays exportateur de pétrole, quelle que soit la règle de politique monétaire. Par ailleurs, l'inclusion de la dépréciation du taux de change dans les règles de politique monétaire permet de réduire les coûts sociaux pour les pays importateurs de pétrole. Enfin, l'ampleur des effets de bien-être dépend du niveau d'inventaire en pétrole à l'état stationnaire et est principalement expliquée par les chocs sur les inventaires en pétrole.In this thesis, I am interested in the effects of fluctuations in oil prices on macroeconomic activity depending on the underlying cause of these fluctuations. The economic models used in this thesis include the Dynamic Stochastic General Equilibrium (DSGE) Models and Vector Autoregressive (VAR) Models. Several studies have examined the effects of fluctuations in oil price on the main macroeconomic variables, but very few of theses studies have specifically made the link between the effects of fluctuations in oil prices and the origin of these fluctuations. However, it is widely accepted in more recent studies that oil price increases may have very different effects depending on the underlying cause of that increase. My thesis, structured in three chapters, is focused on the sources of fluctuations in oil price and their impacts on the macroeconomic activity in general, and in particular on the canadian economy. The first chapter of the thesis investigates how oil supply shocks, aggregate demand shocks, and precautionary oil demand shocks affect Canada's economy, within an estimated Dynamic Stochastic General Equilibrium (DSGE) model. The estimation is conducted using Bayesian methods, with Canadian quarterly data from 1983Q1 to 2010Q4. The results suggest that the dynamic effects of oil price shocks on Canadian macroeconomic variables vary according to their sources. In particular, a 10% increase in the real price of oil driven by positive foreign aggregate demand shocks has a significant positive effect of about 0.4% on Canada's real GDP upon impact and the effect remains positive over time. In contrast, an increase in the real price of oil driven by negative foreign oil supply shocks or by positive precautionary oil demand shocks causes an insignificant effect on Canada's real GDP upon impact but causes a slightly significant decline afterwards. The intuition is that a positive innovation in aggregate demand tends to increase the demand for Canada's overall exports. Oil supply disruptions in foreign countries or positive precautionary oil demand shocks increase the uncertainty about future oil prices, which leads firms to postpone irreversible investment expenditures, and tends to reduce Canada's real GDP. Furthermore, among the identified oil shocks, foreign aggregate demand shocks have been relatively more important in explaining the variations of most of Canadian macroeconomic variables over the estimation period. The second chapter examines the links between oil demand and supply shocks and labor market adjustments in Canadian manufacturing industries using a panel structural VAR model. The model is estimated with disaggregated annual data at the industry level from 1975 to 2008. The results show that a positive aggregate demand shock increases both labor and the price of labor over a 20-year period. A negative oil supply shock has a relatively small negative effect upon impact but the effect turns positive after the first year. In contrast, a positive precautionary oil demand shock has a negative impact over all horizons. The paper also examines how the responses to different types of oil shocks vary from industry to industry. The results suggest that industries with higher net trade exposure/oil-intensity are more vulnerable to oil price increases driven by oil supply shocks and aggregate demand shocks. The third chapter examines the welfare implications of introducing competitive storage on the global oil market using a three country DSGE model characterized by two oil-importing countries and one oil-exporting country. The welfare gains are measured by consumption compensating variation under two alternative monetary policy rules. The main results indicate that the introduction of oil storage has negative welfare effects for each of the two oil importing countries, while it has positive welfare effects for the oil exporting country, whatever the monetary policy rule. I also found that including the exchange rate depreciation in the monetary policy rules allows to slightly reduce the welfare costs for both oil importing countries. Finally, the magnitude of the welfare effects depends on the steady state level of oil storage and is mainly driven by oil storage shocks.

Full textAbstract:
This research project examined the psychometric properties of the adult learner self-directedness scale (ALSDS). The study assessed the construct validity and reliability of the scale as a measure of adult learner self-directedness for diverse groups of adult learners in the South African open, distance and e-learning higher education (ODeLHE) context. The study also assessed whether the factorial structure of the ALSDS was equivalent for adult learners across gender, race and age groups. Furthermore, the study assessed whether the various socio-demographic groups differed significantly on the sub-scale dimensions of the ALSDS; and explored whether a range of socio-biographical factors predicted adult learner self-directedness.
This doctoral study has extended the student’s initial exploratory master’s study on the development and factorial structure of the ALSDS that involved a stratified random sample (N = 1 102) of ODeLHE adult learners. The secondary data set involved a random subsample of n = 747 of the original master’s sample data set. Exploratory structural equation modelling (ESEM), exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) revealed a three-factor solution for the ALSDS, with 15 items loading onto the three factors. The results provided evidence of the construct (convergent and discriminant) validity and internal consistency reliability of the three-factor ALSDS, including the construct equivalence of the scale’s factorial structure across the gender, race and age groups. Significant differences between age, race and gender groups were observed regarding the scale sub-dimensions. The study advances theory on adult learner self-directedness in ODeLHE contexts and contributed evidence of the validity and reliability of a shortened version of the ALSDS as a useful measure of adult learner self-directedness. Psychometric shortcomings to be addressed in future research were also directedness. Psychometric shortcomings to be addressed in future research were also highlighted. Practically, the study highlighted assessing adult learners’ success orientation in ODeLHE, active academic activity and strategic utilisation of resources as aspects of enhancing their self-directedness. Support practices should be considered for especially females, black Africans and younger learner cohorts. ODeLHE practices should also consider learners’ mark for English, gender, access to library, number of modules and who students support financially as factors influencing learners’ level of self-directedness.Abstract/summary in English, Afrikaans and isiZulu
Die navorsingsprojek het die psigometriese eienskappe van die selfgerigtheidskaal vir die volwasse leerder (ALSDS) ondersoek. Die studie het die konstruk-geldigheid en -betroubaarheid van die skaal geassesseer as 'n maatstaf van selfgerigtheid by volwasse leerders vir diverse groepe van volwasse leerders in die Suid-Afrikaanse ope, afstands- en e-leer-hoëronderwyskonteks (ODeLHE). Die studie het ook geassesseer of die fakulteitstruktuur van die ALSDS gelykstaande was vir volwasse leerders oor geslags-, rasse- en ouderdomsgroepe heen. Verder het die studie geassesseer of die verskeie sosiodemografiese groepe beduidend verskil het op die subskaal-dimensies van die ALSDS en ondersoek of 'n reeks sosiobiografiese faktore selfgerigtheid by volwasse leerders voorspel het. Hierdie doktorale studie het uitgebrei op die student se aanvanklike verkennende meesterstudie oor die ontwikkeling en fakulteitstruktuur van die ALSDS wat 'n gestratifiseerde ewekansige steekproef van ODeLHE-volwasse leerders behels het (N = 1 102). Die sekondêre datastel het 'n ewekansige substeekproef behels van n = 747 van die oorspronklike meestersteekproef-datastel. Verkennende strukturele vergelykingsmodellering, verkennende faktorontleding en bekragtigende faktorontleding het 'n driefaktor-oplossing vir die ALSDS onthul, met 15 items wat op die drie faktore gelaai is. Die resultate verskaf bewyse van die konstruk (konvergerende en diskriminerende) geldigheid en interne konsekwentheid en betroubaarheid van die driefaktor-ALSDS, insluitende die konstruk-ekwivalensie van die skaal se fakulteitstruktuur oor die geslags, rasse- en ouderdomsgroepe heen. Beduidende verskille tussen ouderdoms-, rasse- en geslagsgroepe is waargeneem rakende die skaalsubdimensies. Die studie bevorder teorie oor selfgerigtheid by volwasse leerders in ODeLHE-kontekste en dra bewyse van die geldigheid en betroubaarheid van 'n verkorte weergawe van die ALSDS as 'n nuttige maatstaf van selfgerigtheid by volwasse leerders. Psigometriese tekortkomings wat in toekomstige navorsing hanteer kan word, is ook beklemtoon. Prakties gesproke beklemtoon die studie die assessering van volwasse leerders se sukses-oriëntering in ODeLHE, aktiewe akademiese aktiwiteit en strategiese gebruik van hulpbronne as aspekte om hul selfgerigtheid te bevorder. Ondersteuningspraktyke moet oorweeg word vir veral vroue, swart Afrikaners en jonger leerderkohorte. ODeLHE-praktyke moet ook leerders se punt vir Engels, geslag, toegang tot 'n biblioteek, aantal modules en wie studente finansieel ondersteun, oorweeg as faktore wat leerders se vlak van selfgerigtheid beïnvloed.
Le projekthi yocwaningo, ihlola ama-psychometric properties of the adult learner self-directedness scale (ALSDS). Ucwaningo luhlola i-construct validity nokuthembeka kwe-scale njengendlela yokukala i-adult self-directedness kumaqembu ehlukene abafundi abadala kwisimo semfundo evulekile lapho abantu abafunda bekude esibizwa nge-South African open, distance and e-learning higher education (ODeLHE). Ucwaningo lubuye lwahlola nokuthi ngabe isimo ngamaqiniso e-ALSDS siyalingana yini kubafundi abadala kumaqembu obubili, bezinhlanga ezehlukene ngokwebala kanye nabantu beminyaka ehlukene. Kanti futhi okunye, ucwaningo, luhlola ukuthi ngabe amaqembu emikhakha ehlukene ngokwe-sociodemographic ehlukene kakhulu maqondana nama-dimention e-ALSDS acutshungulwayo ukuthi ngabe ama-range emibandela yama-sociodemographic abonelela noma aqagela inqubo ye-adult leaner self-directedness. Lolu cwaningo lweziqu ze-doctoral study lubheke nocwaningo lokuqala lwabafundi be-masters ngentuthuko yesakhiwo se-factoral structure ye-ALSDS ebandakanye amasampuli akhethwe nje ngaphandle kokukhetha noma ukubeka imibandela ethize, okwaziwa nge-stratified random sample ye (N = 1 102) yabafundi abadala be-ODeLHE. Isethi ye-data yesekondari yona ibandakanya i-random subsample of n = 747 yesethi ye-data yabafundi bokuqala be-masters. I-Exploratory structural equation modelling, i-exploratory factor analysis kanye ne-confirmatory factor analysis eziveze izixazululo ezintathu ngama-ALSDS kuma-ayithemu angu 15 afakelwe kuma-factor amathathu. Imiphumela iveza ubufakazi be-construct (i-convergent and discriminant) validity kanye ne-internal consistency reliability yama-factor amathathu e-ALSDS abandakanya i- ix construct equivalence ye-scale's factorial structure, ukunqamuleza kumaqembu ngobulili, izinhlanga ezehlukene ngokwebala kanye neminyaka yobudala ehlukene. Umehluko osemqoka phakathi kweminyaka yobudala, izinhlanga ezehlukene ngokwebala kanye namaqembu eminyaka ehlukene uye wabonakaka maqondana ne-scale sub-dimensions. Ucwaningo luqhubela phambili ithiyori kwizimo zabafundi zokuziqhuba ngokufunda ezibizwa i-adult learner self-directedness kwi-ODeLHE, kanti futhi ithela esivivaneni kwi-reliability ye-version efinyeziwe ye-ALSDS njengesikali esiwusizo kwi-adult learner self-directedness. Okuyizihibe nge-psychometric okufanele kubhekwane nakho ngocwaningo lwangekusasa, kuye kwavezwa kwagqanyiswa. Ngokubonakala ngendlela ebambekayo, ucwaningo lugqamise ukuhlolwa kwempumelelo yabafundi abadala kwi-ODeLHE, umsebenzi omatasatasa we-akhademiki kanye nokusetshenziswa ngendlela yamasu abambekayo kwemithombo njengengxenye yokuthuthukisa i-self-directedness. Izinkambiso zokusekela kumele zibonelelwe, ikakhulukazi kwabesimame, abamnyama bama-Afrika kanye nabafundi abasebasha. Izinkambiso ze-ODeLHE kumele zibonelele namamaki abafundi olimi lwesiNgisi (i-English), ubulili, ukufinyelela emalayibhrari, inani lama-module kanye nokuthi ngabe abafundi bondla obani ngokwezimali njengemibandela enomthelela kwinqubo yokuthi abafundi bakwazi ukuziqhubela phambili ngokwenqubo ye-self-directedness.
