The enhancement of bioremediation by bioaugmentation in soil contaminated with diesel fuel No. 2 and No. 6 (Bunker C) is uncertain. A clayey soil was contaminated with 6,000 mg of either diesel fuel per kg of soil and seeded (5 x 10-7 cells/g of soil) with a Hawaii soil bacterium (UH138) known to utilize several hydrocarbons. The soil was limed, fertilized, and incubated in jars at 30°C for several months. The concentrations of total petroleum hydrocarbons (TPH) and of polycyclic aromatic hydrocarbons (PAH) in soil were measured by gravimetry and immunoassay, respectively. Poisoned controls (0.6% HgCl2) were used to determine the extent of hydrocarbon degradation due to microbial activity. A rapid first order biodegradation of TPH (84% in 23 days) occurred in soil contaminated with diesel fuel No. 2, regardless of bacterial seeding. Biodegradation of PAH was linear and reached 84% by day 98 in both seeded and unseeded treatments. Bioaugmentation had no effect on bioremediation of diesel fuel No.2. The decrease in TPH and PAH was paralleled by an increase in populations of total bacteria, phenanthrene-degrading bacteria and microorganisms capable of utilizing hexadecane and diesel fuel No. 2 as well as by an enhancement in CO2 evolution by the soil. Indigenous Zygomycetes grew profusely in diesel fuel No. 2 contaminated soil. Cunninghamella echinulata var. echinulata was isolated from the soil and was shown to be able to utilize several hydrocarbons. Thus, Zygomycetes may have contributed to the rapid decrease in contaminant. In soil contaminated with diesel fuel No. 6, the measurements of TPH and PAH were more variable due to the uneven distribution of the product. No biodegradation of the contaminant occurred over a period of 138 days. The growth of Zygomycetes was scant. The counts of total bacteria remained unchanged after the addition of diesel fuel No. 6. However, counts of the indigenous phenanthrene-degrading bacteria increases dramatically ( 4 log units) during the first 54 days whereas the level of the seeded bacteria remained stable. The counts of mineral oil degraders decrease by 2 log units after day 2. Co2 evolution from the soil confirmed that diesel fuel No. 6 was not degraded by either the indigenous microflora or the seeded bacterium. Thus, diesel fuel No. 2 was highly degradable by the indigenous population, however, diesel fuel No. 6 was recalcitrant.

Ever since the first Industrial Revolution, during which many textile artisans lost their jobs to weaving machines, the relationship between technological progress and unemployment has been explored and examined by researchers and policy makers. Existing empirical research, mostly at the microeconomic level, has presented ambiguous results. Procuring data on 51 U.S. states for a period of 19 years and a large number of controls, this paper studies the employment effect of technological innovations with a novel state-level macroeconomic analysis. Using commercially-supplied Research and Development expenditure as a proxy, this paper finds that although technological innovations have a non-significant effect on employment at the general state level, there are a few factors that determine how well each state’s labor market responds to technological changes. More specifically, non-urbanized, non-tech-savvy, or states with a large number of workers employed in Manufacturing or Accommodation and Food Services industry experience a more severe unemployment effect than the other states. The results also suggest that unemployment rate is more negatively affected by technological innovations during the Obama Administration, compared with the Clinton and Bush Administration. This paper adds to the limited, macroeconomic literature on technological unemployment, and provides policy makers with important implications on how to prepare citizens for the imminent waves of technological changes.

Thesis (DTech (Information Technology))--Cape Peninsula University of Technology, 2017.
Rationale: Unavoidably, the 21st century is witnessing continuous discourse about students’ technology uses in higher education. This thesis explores the underpinnings of students’ technology usage in their rhizomatic (personal) learning networks in the higher educational environment through a lens of four sub-research questions and four research hypotheses. Methodology: This research adopted a cross-sectional narrative and numeric study using the Frameworks for an Integrated Methodology (FraIM). The study was conducted in four universities comprising two universities in Ghana, one in South Africa and another in Belgium. Participants and respondents included students and lecturers. Data collection methods comprise focus group interviews, individual interviews, surveys (paper and web-based) and rhizomatic maps. The philosophical underpinning was inclined towards the critical realists’ stance and hinged to Rhizome Theory and Actor Network Theory. Data were analysed through descriptive and multivariate analyses and learning analytics employing tools in social network analysis. Results were presented graphically via Rhizomatic Learning Network maps, charts, tables and narratives. Findings: Students’ personal learning networks exhibit traces of rhizomatic patterns which are related through human and non-human actors. Seven categories of actors – comprising 218 individual actors – were found in students’ Rhizomatic Learning Networks. Out of 19 traceable digital devices used by students, this research established differences among the institutions in the four most widely used digital devices: Laptop, Smartphone, Tablet or iPad, and E-Reader pro rata. Students owned, in this sequence, smartphones, laptops, tablets or iPads and e-readers. This research also found statistically significant differences among all four institutions in terms of students’ self-perceived importance of handheld mobile devices towards academic success, university wireless network experiences and satisfaction of Learning Management Systems in the universities. However, results indicated that students are not likely to skip classes when materials from course lectures are available online, implying an inclination towards a blended approach to learning despite a technologically-rich environment. Implications and Value: With an underlying effect on curriculum design and implementation, this thesis, supporting rhizomatic approaches to learning, has tremendous potential to improve personal learning networks in higher education. It further contributes an understanding of emerging patterns in the personal learning networks of higher education students within a technology-rich environment. Again, integration of the two theories – FraIM, analytical tools and style of presentation – in understanding the problem through the lens of a critical realist is novel. Key Recommendations: Further rhizoanalysis research into the detailed roles performed by individual technological actors in students’ personal learning networks in the higher educational environment is required. Additionally, clear policies exhibiting willingness and enforcement strategies to integrate technology in all facets relating to learning should guide curriculum development within the universities.

Augmentative communicators are perceived to have difficulty with reading and writing. This research investigates the effect of increased opportunity to communicate via telecommunications on the reading and writing of adult augmentative communicators who are severely disabled. Two case studies were conducted utilizing a single subject, repeated measure design. The subject of each case study participated in on-line interactive Blissymbol telecommunications sessions with a speaking partner for nine hours per week over ten months. Reading and language tests were administered at two month intervals. Written transcripts of on-line conversations were collected and coded according to macro and micro language functions. Following the increased opportunity to communicate via telecommunications, case study two paralleled the results found in case study one displaying increased reading ability as demonstrated by the upward trends on the multiple reading measures utilized. Case study two also corroborated case study one in the written communication as demonstrated by the increased use of complex language functions, initiations, and response to statements. The findings suggest that providing augmentative communicators with meaningful and functional reading, writing, and 'speaking' opportunities, similar to those provided with the telecommunications opportunity in this research, will have a positive effect on reading and writing.

The starting point of this research is the observation that tutors in the Computing Sciences (CS) Department at NMMU require more support than they currently receive in order to be effective. This research project investigated how technology could be used to support tutors during practical sessions. Focus group discussions with tutors in the CS Department revealed that challenges exist which hinder them from effectively assisting students during practical sessions. Through analysis of focus group discussions and literature regarding the use of technology in education, it was determined that a tablet PC could be used to support tutors by providing on-demand access to practical content and answers to frequently asked questions. Existing models using technology in education to support either students or tutors in learning were investigated. A conceptual model using technology to support tutors during practical sessions was designed and proposed based on features of the existing models which were considered relevant to the CS context, and ways in which they could support tutors. Relevant features of the conceptual model include the system, purpose, boundary, key variables and best practices applied to the technological component of the model. During development of the model, these features were considered. In the context of the CS Department, a tablet PC tool was used by tutors as a means to support themselves and assist students during practical sessions. The tool is a component of the model which provides practical information. Each layer of the model’s three layer architecture was tested to ensure that the correct information is provided, on demand, to tutors during practical sessions. Positive results from a field study evaluation revealed that the conceptual model, using a tablet PC tool, could be applied to the CS context with the intention of supporting tutors during practical sessions.

Streszczenie:

Learning engagement is essential for fruitful and meaningful learning outcomes. Although many researchers have collectively claimed that social networking technologies in the Web2.0 era possess great potential to foster learning engagement, the existing literature demonstrates the pedagogical significance of more empirical and systematical inquiries into their applications for effective teaching and learning in various educational contexts. A social networking environment (SNE) is an online environment established with these technologies in which various tools, people and resources are dynamically connected. This study aimed to investigate the roles of such an environment in supporting learning engagement in higher education, and to identify factors that affected how students engaged in learning activities in the SNE. Informed by the literature on knowledge construction, collaborative learning and intrinsic motivation, learning engagement was conceptualized as a multidimensional construct that incorporated cognitive, social and emotional components of the learning process. This study was a single case study. It spanned a period of six months with a class of 55 undergraduate students enrolling in an elective university course in mainland China. A SNE, which integrated blogs, wikis, social bookmarks and tagging, file repositories, group spaces, and social networking facilities, was implemented to support designed learning activities that emphasized reflections and social interactions for achieving course objectives. Data collection and analysis combined qualitative and quantitative methods. Multiple-source data was obtained from interviews, observation, questionnaires and student learning artifacts, and was analyzed through content analysis, social network analysis and descriptive statistical analysis. The analysis revealed a number of roles that the SNE could play in supporting learning engagement. In terms of social engagement, it could serve as a social medium for (a) facilitating self-presentation and self-expression, (b) supporting articulation and development of personal social networks, (c) encouraging various levels of participation in social interactions, and (d) enabling personalized feedback. In terms of cognitive engagement, it could afford a hybrid of individual and social learning by (a) supporting development of personal learning portfolios, (b) facilitating peer and teacher feedback, and (c) creating the transparency in a distributed learning environment which enabled students to access multiple perspectives, learn by observation, and utilize metacognitive skills for self-regulated learning. In terms of emotional engagement, it could be used as a vehicle for developing a socio-affective structure of the learning community by (a) inducing expression of emotions and feelings, (b) fostering socio-emotional interactions, and (c) contributing a sense of being connected to others. Factors in cultural, socio-contextual, technical, and individual dimensions were identified that affected learning engagement in the SNE and needed to be addressed in pedagogical interventions. This study has both theoretical and practical implications. By proposing a construct incorporating cognitive, social and emotional elements of engaged learning, it deepens our understanding of the relationship between learning engagement and educational use of social networking technologies in higher education. For practicing teachers, a set of pedagogical principles is suggested based on the findings of the study for facilitating learning engagement in the SNE. Implications for software designers and educational administrators are also discussed.

The purpose of this study was to determine the relationship between principals' leadership styles and principals'/teachers' implementation of technology. The Leadership Effectiveness and Adaptability Description (LEAD) Self was used to identify the primary and secondary leadership styles of principals. The Level of Technology Implementation (LoTi) Questionnaire was used to identify the level of technology implementation (LoTi), personal computer use (PCU) and current instructional practice (CIP) scores for both teachers and principals. Data collected from 390 K-12 teachers and 22 principals of three large suburban districts in the Dallas-Fort Worth Metroplex was included in data analysis. The findings suggest that differing leadership styles do play a role in the LoTi, PCU, and CIP scores among teachers. Based on descriptive statistics it was determined that teachers with "participating" principals had higher mean LoTi and PCU scores than those with "telling" and "selling" principals. The difference in the mean PCU scores was statistically significant (p<.05) for teachers with "selling" and "participating" principals. Results also showed there was a statistical significance (p<.05) in the mean PCU and CIP scores of teachers working for principals with weak and high adaptability. Due to the low number of principals participating in this study, there is a need to conduct the same research using a larger more diverse sample of principals. The majority of principals in this study had either a primary leadership style of "participating" and a secondary leadership style of "selling" or vice versa. A larger population of principals would hopefully allow for the study of additional leadership styles and their effect on teacher use and implementation of technology.

This study examines the history, development and diversity of news agencies. It studies the major agencies and pinpoints how smaller wire services that sometimes purvey niche news seek to offer a more diverse global news-flow. The linkage between news agencies and technological developments, and how wire services have helped advance technology, is examined since the first agencies began in the 1800s, up to the current era of the Internet. The rise of television and the subsequent ascent of the Internet prompted new demands for more diverse news procurement. This accelerated the convergence of different media and has exposed challenges and opportunities to news agencies, large and small. Alongside the telegraph, news wire services expanded from supplying news and information locally to being global players, helping the world shrink. The mediahistoriographical approach engages a critical examination of literature sources regarding the development of the major wire services, and some of the smaller players. The literature, along with interviews with news agency experts, provides the material to examine wire services. The study shows how some original agencies leveraged opportunities offered by their standing in powerful nations to become dominant transnational players. The ascendancy of the mega-agencies compounded limited news-flows from developed to poorer nations, while an expansion of diversified news-flows has not matched technological progression. This study concludes by recommending greater recognition of the importance of news agencies and more scholarly examination of them, as studies on them appear scarce compared to those on other media branches, such as newspapers, the electronic media and the Internet. More studies into the development of both mainstream and alternative news agencies would pave the way for a better understanding of how they function and could provide clues as to how they might be able to better sustain themselves as more diverse entities for the benefit of the public discourse. Through the above, this dissertation seeks to contribute, in a small way, to rectifying a knowledge disparity regarding a key component of the mass media, namely the news agency.

Thesis (MScPhysio (Physiotherapy))--University of Stellenbosch, 2007.
INTRODUCTION Computer use has been identified as a risk factor for the development of musculoskeletal dysfunction among children and adolescents internationally. Computer exposure has increased in the Western Cape since 2002, with the inception of a project to install computer laboratories in all schools in the province. As musculoskeletal dysfunction experienced during adolescence is predictive of musculoskeletal disorders in adulthood, it is essential to identify all risk and/or associative factors. METHODOLOGY A descriptive study was conducted with the aim to investigate whether the musculoskeletal dysfunction of high school learners in the Cape Metropolitan region was related to their computer use. This study was conducted in two phases. Phase 1 of the study entailed the completion of a new questionnaire, the Computer Usage Questionnaire, by grade 10-12 learners. The learner sample was divided in a computer and a non-computer group depending on their exposure to the school computer. Phase 2 of the study involved the assessment of the ergonomic design of the computer laboratories at randomly selected high schools within the Cape Metropolitan region. RESULTS A total of 1073 learners (65% girls & 35% boys), aged 14-18 years, completed the CUQ in phase 1 of the study. The results indicated that learners in the computer group had greater weekly exposure to computers than the non-computer group. The prevalence of musculoskeletal dysfunction among this learner sample was 74%. The most common body areas of dysfunction were the head, low back and neck. The female gender, playing sport and using the school computer for more than three years were associated with musculoskeletal dysfunction. Weekly computer use of more than seven hours was predictive of general musculoskeletal dysfunction, low back pain and neck pain. Twenty nine computer laboratories within 16 selected high schools were assessed by means of the Computer Workstation Design Assessment (CWDA). Out of a total score of 40, the computer laboratories obtained average scores of less than 45%, indicating compliance with less than half of the standard ergonomic requirements. The average scores for the workspace environment was less than 40%. The design of the desk, chair and computer screen had the poorest compliance to ergonomic guidelines. DISCUSSION AND CONCLUSION The prevalence of musculoskeletal dysfunction among this sample was higher than among other similar samples on the same study topic. The higher prevalence may be attributed to the poor ergonomic design of the computer laboratories in the Cape Metropolitan region. Learners’ reduced participation in activities such as sport and working on a computer due to their musculoskeletal dysfunction, may impact on their choice of a future career. The tendency of learners not to seek medical advice for their musculoskeletal dysfunction may predispose the development of chronic musculoskeletal disorders. Education of related parties on safe computing habits as well as advice on the ergonomic design of computer laboratories is recommended to prevent the progression of adolescent musculoskeletal dysfunction into chronic disorders in adulthood.

This study investigated the strategies employed by adjunct writing teachers in their attempts to reconcile changes in writing program policy with their existing pedagogies. The methods of investigation combined class observation with extensive interviews with three Ball State University adjunct faculty members to identify the means by which these writing instructors brought new pedagogical goals in their classrooms. It also sought to identify the mechanisms each teacher used to integrate computer-oriented teaching styles into his or her course planning. The purpose of this study was to identify means by which a writing program administration could better introduce change to its teachers of first year composition courses, who are largely adjunct staff.The results of this study showed that while each faculty member felt committed to using technology in his or her teaching, each confronted change differently. Studies in faculty vitality were examined to identify development strategies which could effectively address the differences in faculty change. This study recommends, based on the strategies of each participant, that writing programs seek more kairic models of development. These models would seek to foster continuous discussion of change in order that fitting incentives for development could arise in "the proper time," or kairically, for individual teachers.

Streszczenie:

Computer professionals have been agents of change in many organizations. In some cases the role inadvertently became theirs as they were the ones at the vanguard of implementing the new information processing technology in organizations. While in other cases they were the catalysts for change, to force new methods/procedures onto lethargic organizations. While introducing change on others in the organization and adapting to new technological changes themselves, the computer professionals have not really had to face a significant change in their status, power, or importance to the organization. The introduction of the personal computer has brought about significant change in the way the job of the computer professional is perceived by many in the business world. While this change is personally affecting the way they do their job, there has not been a noticeable attempt by those managing computer professionals to deal with the human emotions engendered by such a change. Part of the reason for this lack of attention may be due to the lack of a model as to how computer professionals react to change. Such a model would provide a system whereby it would be possible to recognize where efforts could be made to measure, predict, and modify situations so that a smooth transition can be made to the change. Toward this end a model was developed which presents a system as to how computer professionals react to change. This dissertation presents the model, surveys a population of computer professionals, and analyzes the model using data gathered from the population. The data was gathered in the form of a self administered survey which was given to computer professionals working for six investor owned electric and gas utilities in the Northwestern United states. They answered questions on a scale of from one to five as to their emotions and perceptions about the introduction of personal computers into their organizations. These questions spanned the timeframe as the organizations migrated from the early beginnings of personal computer introduction, to a situation where the use of personal computers was widespread in the company. In the case of three of the companies the personal computer had not yet achieved widespread use at the time of the survey. The data gathered from the computer professionals was statistically analyzed to see if relationships exist between the model and the data. Additionally, interesting demographic data was analyzed to see if certain other factors affected the computer professional's perception as to the impact of the personal computer on their quality of worklife.

Streszczenie:

This dissertation is motivated by an overarching research question: How do firms leverage external resources residing in their ego network (portfolio of alliances) and their clusters in order to innovate in a sustained manner? Research suggests that firms often struggle and falter in their innovation efforts. However, past research has paid little systematic attention on why firms struggle in their innovation efforts. Further, though network and clustersâ the key sources of external resourcesâ may overlap in several ways, the extant literature has not examined their joint effect on a firm's technological innovation. In this dissertation, using a longitudinal research design I examine how the characteristics of a firm's ego network and of its cluster independently and jointly impact its patent output in the U.S. semiconductor industry. The research provides a framework showing how networks and clusters may work in tandem in helping a firm overcome innovation barriers. The study demonstrates how firms can leverage network and cluster resources. The empirical evidence indicates that the efficacy of cluster resources increases in the presence of network ties within the cluster. It also shows that firms can mobilize resources of distant clusters using their network ties. The study further demonstrates that resource-rich firms leverage networks resources more effectively than the resource-deficient firms do while resource-deficient firms leverage cluster resources more effectively than the resource-rich firms do. The dissertation makes important theoretical and empirical contributions to alliance, network, cluster, and innovation literatures. The research findings also have important managerial implications.

A inovação é considerada um dos fatores fundamentais para o desempenho das organizações. Na área da saúde, sobretudo na indústria farmacêutica, a inovação representa sua força motriz. O mercado farmacêutico global vem enfrentando diversos desafios tais como a concorrência acirrada dos medicamentos genéricos, o aumento do rigor regulatório e dos custos de desenvolvimento de novas drogas, bem como a pressão dos governos para redução dos seus gastos com saúde. Neste cenário, a capacidade de inovação permanente será fator crítico para a busca da vantagem competitiva sustentável. Essa pesquisa tem como objetivo identificar o nível de desenvolvimento de competências para a inovação e até que ponto a presença destas competências, em uma amostra de empresas nacionais da indústria farmacêutica brasileira, está relacionada com seu desempenho competitivo. Inicialmente foram realizados levantamento bibliográfico e a aplicação de um questionário, construído especificamente para o setor analisado. A análise dos dados coletados resultou na identificação de níveis baixos e médios de internalização das competências para inovar. Como esperado, o grupo de empresas com maior nível de desenvolvimento dessas competências apresentou graus mais elevados em relação às variáveis de desempenho. O estudo evidenciou, ainda, que as competências "Inserir a Inovação na Estratégia da Organização" e "Cooperar para as inovações", possuem um relacionamento positivo direto com a margem líquida das empresas pesquisadas.

This research is aimed at understanding the development of media skills in schools in the context of cybercultural dromocracy. The primary objective is to understand these skills and their links with the social, economic and media context of the school, as well as the perspective of valuing technology in this environment. The corpus of the research will consist of interviews with pedagogical coordinators of the Mater Dei School, a private teaching institution in the city of São Paulo. The school provides digital media for educational purposes as part of the execution of its educational policy project. Intended for the regular activities of all curricular components, digital media are intrinsically linked to students' school routine. In these cases, the development of media skills is at stake, and that’s the central focus of the research. This concept is understood as the sum of technical, practical and cognitive skills that covers both the use of the media and the critical understanding of macrossocial and mediatic processes. As a consequence of technological development, the social, cultural, economic and/or political contexts of life were eventually mediatized, a scenario in which the media permeate the development of contemporary society. In the same context, new models of construction and mediation of knowledge emerge, prompted by the imperative of cyberculture dromocracy in this mediatized capitalist structure. In this scenario, which justifies the need for an in-depth investigation, the research problem concerns how and to what extent the institution appropriates the discourse of competence and/or dromocracy in order to determine the development of media skills in the school system. As a methodological strategy, the interviews with educational managers at the Mater Dei School, as well as the mapping of the characteristics of the school system studied, are based on the following hypothesis: a school has learning objectives focused on the development of media skills, incorporated into the curriculum of pedagogical coordination and teachers, as a consequence of demands outside the school, such as the need to train students able to deal with digital technologies
A presente pesquisa está dedicada à compreensão do desenvolvimento de competências midiáticas em escolas no contexto da dromocracia cibercultural. O objetivo prioritário é a compreensão dessas habilidades e seus vínculos com o contexto socioeconômico e midiático da escola, bem como a perspectiva de valorização da tecnologia nesse ambiente. O corpus da pesquisa consistiu em entrevistas com coordenadores pedagógicos do Colégio Mater Dei, instituição particular de ensino da cidade de São Paulo. A escola disponibiliza mídias digitais para fins educacionais como parte da execução de seu projeto político-pedagógico. Destinadas as atividades regulares de todos os componentes curriculares, as mídias digitais estão, intrinsecamente, ligadas ao cotidiano escolar dos alunos. Está em jogo, neste caso, o desenvolvimento de competências midiáticas — foco central da Pesquisa. Entende-se por este conceito a soma das habilidades técnicas, práticas e cognitivas que abrangem tanto o uso das mídias quanto a compreensão crítica de processos macrossociais e midiáticos. Como consequência do desenvolvimento tecnológico, os contextos sociais, culturais, econômicos e/ou políticos de vida acabaram por ser midiatizados, cenário no qual os meios de comunicação perpassam o modo de desenvolvimento da sociedade contemporânea. No mesmo contexto, emergem novos modelos de construção e mediação do conhecimento, solicitados pelo imperativo da dromocracia cibercultural nessa estrutura capitalista midiatizada. À luz desse panorama, que justifica a necessidade de uma investigação aprofundada, a problemática da pesquisa diz respeito a como e em qual medida a instituição se apropria do discurso da competência e/ou da dromocracia, de modo a determinar o desenvolvimento de competências midiáticas no sistema escolar. Privilegiando, como estratégia metodológica, entrevistas com gestores educacionais no Colégio Mater Dei, bem como o mapeamento das características do sistema escolar estudado, esta Pesquisa se baseia na seguinte hipótese: a escola dispõe de objetivos de aprendizagem focados no desenvolvimento das competências midiáticas, incorporados ao currículo de forma objetiva pela coordenação pedagógica e pelos professores, em consequência de demandas externas à escola, como a necessidade de formação de alunos aptos a lidar com as tecnologias digitais

ENGLISH ABSTRACT: Innovation can be defined as a process whereby radical and incremental changes in thinking, in a process and in services lead to novel processes, products and services on a global scale. The nature of this “process” distinguishes it from similar processes concerning development and competitiveness with which it is often confused. Given their unique characteristics and challenges, cities are often the ideal and most likely sites for innovation in a globalised world. In the past, cities were mainly tasked with managing the affairs of their citizens. However, modern-day cities often find themselves facing more significant challenges, such as competing with other cities for investment, knowledge and tourists. In addition, cities in the 21st century are challenged to develop city cultures that are conducive to a knowledge-based economy and lifestyle. Against this background, the purpose of this thesis was to determine the relationship between innovation and cities in a knowledge-based economy (chapter 1). The chosen research methodology entailed critically analysing core concepts, namely cities (chapter 2), innovation (chapter 3), and the relationship between cities and innovation in the knowledge economy (chapter 4). Based on this, the researcher proceeded to postulate recommendations and suggestions for policies of innovation in cities (chapter 5). In so doing, the foundation was laid for the future development of a policy regarding innovation in developing cities (chapter 6).
AFRIKAANSE OPSOMMING: Innovasie kan gedefinieer word as ’n proses bestaande uit radikale en inkrementele veranderinge in denkpatrone, in ‘n proses, produkte en dienste wat uiting kry in die ontwikkeling van nuwe prosesse, produkte en dienste op ‘n globale skaal. Die aard van hierdie “proses” onderskei dit van soortgelyke prosesse rakende ontwikkeling en mededingendheid waarmee dit menigmaal verwar word. Stede word dikwels beskou as die ideale (en mees waarskynlike) gebiede waar innovasie in ’n geglobaliseerde wêreld kan plaasvind, vanweē hul unieke karaktereienskappe en die uitdagings wat hulle in die gesig staar. In die verlede was stede slegs belas met die belange van hul inwoners, maar hedendaagse stede moet dikwels ander uitdagings, soos strawwe kompetisie vir beleggings, kennis en toeriste, teen ander stede die hoof bied. Terselfdertyd, word daar van stede in die 21ste eeu verwag om stedelike kulture te ontwikkel wat bevorderlik is vir ’n kennis-gebaseerde ekonomie en leefstyl. Teen hierdie agtergrond was die doel van hierdie tesis om die aard van die verhouding tussen innovasie en stede te bepaal (hoofstuk 1). Die gekose navorsingsmetodologie het die kritiese analise van kernkonsepte behels, naamlik stede (hoofstuk 2), innovasie (hoofstuk 3) en die verhouding tussen stede en innovasie in die kennisekonomie (hoofstuk 4). Op grond van hierdie analise, het die navorser aanbevelings en voorstelle rakende innovasie-beleide in stede gepostuleer en geformuleer (hoofstuk 5). Op hierdie manier, kon die grondslag gelê word vir die toekomstige ontwikkeling van ’n beleid vir innovasie in ontwikkelende stede (hoofstuk 6).

Recent Canadian statistics have shown a dramatic decrease in women enrolling in computer science courses at the university level. This study presents quantitative and qualitative research that forms a profile of the family background, schooling experiences and personal characteristics of women who are successful computer science students at this level. Forty-five male and female technology students were surveyed to determine emerging gender differences and 4 females were interviewed. Contrary to previous studies, the lack of early and extensive computer experience did not limit these women. Recommendations for increasing female participation in computer culture include providing parents, teachers, and students with career information and improving critical problem solving skills in math instruction.

ENGLISH ABSTRACT: Dried fruit is a well-known food product that has been produced for many years. The product characteristics have remained constant throughout this time with a moisture content of ca. 18 - 26% (mlm). However, in recent times there has been a definite trend towards a fmal dried fruit product in the intermediate moisture range with a moisture content of ca. 36%. The high water activity (aw) of the product (ca. 0.85) makes the product susceptible to microbiological spoilage and the product therefore requires a subsequent pasteurisation step to ensure a safe product. A further consequence of the increased moisture content, higher aw and the temperature of the pasteurisation step, is the increased rate of non-enzymatic browning reactions. Currently the shelf life is only 15 weeks while a minimum shelf life of 30 weeks is required to enable product export. Moisture sorption isotherms may be used to depict the relationship between moisture content and aw. Moisture sorption isotherms were thus determined for Royal type apricots and nectarines at 25° and 40°C. Samples, equilibrated at relative humidities in the range of 11-97%, were obtained using saturated salt solutions and a static gravimetric method. Isotherms were found to be of type I, typical of dried fruit. Six mathematical models namely; BET, GAB, Iglesias and Chirife, Halsey, Henderson, and Chung and Pfost, were fitted to experimental data. The GAB model predicted the aw of both apricots and nectarines the best at 25° and 40°C with the Henderson equation second best in all instances. The binding energy, as a function of moisture content, was calculated to determine energy requirements for drying. At low moisture contents « 20%) an increase of energy was required for drying. Discolouration of macerated dried Royal type apricots and nectarines during accelerated storage as affected by moisture (32, 36, and 40%, mlm) and sulphur dioxide (S02) content (2500, 3000 and 3300 mg.kg" for apricots; 1800, 2200 and 2600 mg.kg" for nectarines) was investigated. The macerated samples were stored at 30°, 40°, 50° and 60°C. Colour was quantified in terms of the L* value of the CIELab system (used throughout the study). Moisture and S02 contents affected both the initial fruit colour and the rate of discolouration. The highest L* values, i.e. lightest fruit colour, were obtained for fruit at 40% moisture content and the highest S02 levels. Increasing storage temperature accelerated the loss of moisture and S02. The influence of a 10°C increase in storage temperature on the rate of browning and thus shelf life was described in terms of the QIO value. QIO and aw values of apricots ranged from 1.96 - 2.47 and 0.833 - 0.890, respectively, while QIO values of 1.50 - 4.61 and aw values ofO.844 to 0.890 were obtained for nectarines. Discolouration of dried nectarine halves during accelerated storage at 40°C as affected by rehydration method, moisture content, packaging atmosphere and pasteurisation method, was investigated. The fruit halves were rehydrated using three different methods to obtain moisture contents of 36 and 40%, respectively. Dry heat and steam pasteurisation techniques were used to render a microbiologically safe product. Commercial packaging material was used and the atmosphere was modified with CO2 to lower the O2 concentration in the headspace. A two-step rehydration at 45°C, steam pasteurisation at 90°C for 150 minutes and packaging under a high CO2 atmosphere rendered a product with the best colour retention under accelerated storage conditions of 40°C for eight weeks. To confirm the results obtained with accelerated storage at temperatures that the product would normally be retailed at, shelf life tests were also performed at 5° and 25°C. Discolouration of whole dried Royal type apricot and nectarine halves as affected by rehydration method, moisture content, packaging atmosphere and pasteurisation method was investigated. The methodology for rehydrating, pasteurising and packaging the high moisture dried fruit developed in this study was compared against the standard method used by the industry. The new processing method increased shelf life. Samples were stored for a period of 30 weeks and were tested every five weeks to determine CO2 concentration in headspace, colour retention and S02 concentration of the fruit. Both apricots and nectarines achieved a shelf life of 30 weeks at both storage temperatures and an extrapolated shelf life of 89 weeks at 5°C, but only 32 weeks at 25°C.
AFRIKAANSE OPSOMMING: Droë vrugte is 'n welbekende voedselproduk en word reeds vir baie jare vervaardig. Die produkeienskappe het konstant gebly gedurende hierdie tydperk met 'n produkvoginhoud van ca. 18 - 26% (mlm). Daar is egter 'n tendens die afgelope tyd na 'n finale produk in die intermediêre voggebied met 'n voginhoud van ca. 36% en 'n water aktiwiteit (aw) van ca. 0.85. Hierdie verandering in voginhoud en aw maak die produk vatbaar vir mikrobiologiese bederf, en gevolglik word pasteurisasie benodig om dit te preserveer. 'n Verdere gevolg van die verhoogde voginhoud en aw en die hoë temperature van pasteurisasie, is die verhoogde tempo van nieensiematiese verbruiningsreaksies. Huidig is die produk se rakleeftyd 15 weke terwyl 'n minimum van 30 weke benodig word om hierdie produk suksesvol uit te voer. Vogsorpsie-isoterme kan gebruik word om die verwantskap tussen voginhoud en aw uit te beeld. Vogsorpsie-isoterme van Royal tipe applekose en nektariens is gevolglik bepaal by 25° en 40°C. Monsters, geëkwilibreer by relatiewe humiditeite van 11 - 97%, is verkry deur gebruik te maak van versadigde soutoplossings en 'n statiese gravimetriese metode. Tipe I isoterme, wat tipies van droëvrugte is, is verkry. Ses wiskundige modelle naamlik; BET, GAB, Iglesias en Chirife, Halsey, Henderson, en Chung en Pfost, is gepas op die data. Die GAB model het die aw van beide appelkose en nektariens by 25° en 40°C die beste voorspel en die Henderson model die tweede beste in al die gevalle. Die bindingsenergie as 'n funksie van voginhoud is bereken om die energie vereistes van droging te bepaal. By lae voginhoude (<20%) is 'n skerp styging in benodigde energie waargeneem. Die verkleuring van gemaalde gedroogde Royal tipe appelkose en nektariens gedurende versnelde opberging en die invloed van voginhoud (32, 36, en 40%, mlm) en swaweldioksied (S02) konsentrasie (2500, 3000 en 3300 mg.kg' vir appelkose; 1800, 2200 en 2600 mg.kg" vir nektariens) is ondersoek. Die gemaalde monsters is gestoor by 30°, 40°, 50° en 60°C. Kleur is gekwantifiseer in terme van L* waardes van die CIELab sisteem (ook gebruik vir daaropvolgende ondersoeke). Vog en S02 het albei die aanvanklike kleur asook die tempo van verbruining beïnvloed. Die hoogste L* waardes, d.i. die ligste kleur, is verkry vir die monsters met 40% voginhoud en die hoogte S02 vlakke. Verhoogde temperature tydens opberging het aanleiding gegee tot verhoogde verliese van vog en S02. Die invloed van 'n 10°C verhoging in opbergingstemperatuur op die tempo van verbruining en dus rakleeftyd, word beskryf in terme van QIO waardes. QIO en aw waardes van die appelkose het gestrek van 1.96 - 2.47 en 0.833 - 0.890, onderskeidelik, terwyl QIO waardes van 1.50 - 4.61 en aw waardes van 0.844 tot 0.890 verkry is vir die nektariens. Verkleuring van gedroogde nektarien halwes gedurende versnelde opberging by 40°C en die invloed van rehidrasie metode, voginhoud, verpakkingsatmosfeer en pasteurisasiemetode is ondersoek. Die vrughalwes is gerehidreer deur middel van drie metodes om die voginhoud te verhoog tot 36 en 40%, onderskeidelik. Droë hitte en stoompasteurisasie metodes is gebruik om 'n mikrobiologiese veilige produk daar te stel. Kommersiële verpakkingsmateriaal is gebruik en die CO2 konsentrasie van die atmosfeer in die verpakking is verhoog om die invloed daarvan te bepaal. 'n Twee-stap-rehidrasie by 45°C, stoompasteurisasie by 90°C vir 150 minute en 'n hoë C02 atmofeer het aanleiding gegee tot die monster met die beste kleurbehoud tydens versnelde opberging by 40°C vir agt weke. Om die resultate, verkry met die versnelde rakleeftyd studie, te bevestig by temperature waarby die produk normaalweg blootgestel sal word tydens kleinhandel, is 'n rakleeftyd studie uitgevoer by 5° en 25°C. Verkleuring van heel gedroogde Royal tipe appelkoos en nektarien halwes, die invloed van rehidrasie metode, voginhoud, verpakkingsatmosfeer en pasteurisasiemetode is ondersoek. Die metodiek vir die rehidrasie, pasteurisasie en verpakking van hoë vog droëvrugte ontwikkel in hierdie studie, is getoets teen die standaardmetode wat deur die industrie gebruik word. Die nuwe prosesseringsmetode het aanleiding gegee tot 'n langer rakleeftyd. Monsters is opgeberg vir 'n tydperk van 30 weke om die rakleeftyd te bepaal. Die CO2 konsentrasie in die pakkie, kleurbehoud en S02 konsentrasie van die vrugte is elke vyf weke getoets. Beide appelkose en nektariens het 'n rakleeftyd van 30 weke by albei opbergingstemperature behaal, terwyl 'n ekstra-gepoleerde rakleeftyd van 89 weke by 5°C en 32 weke by 25°C behaal is.

Educational technology can improve teaching and learning in universities of technology in developing countries. Due to various factors, there is no readymade “one-size-fits-all” solution for facilitating the successful implementation of educational technology. Tedre, Apiola and Cronjé (2011) identified 100 educational, socioeconomic and technical attributes that can influence the successful integration of educational technology in developing regions. While exploring the issues arising from technology integration at two universities of technology, the aim of this research was to evaluate the effectiveness of Tedre, Apiola and Cronjé’s framework in order to contribute to its refinement. The central research question concerned the extent to which Tedre, Apiola and Cronjé’s framework was useful for a situational analysis at two South African universities of technology. The sub-questions concerned the framework’s ability to distinguish between the two universities on the one hand and on the other hand, the overlaps or shortcomings of the model as it assisted in describing those situations. The findings revealed that the two universities in this inquiry are not similar. Although the universities’ educational strategies and policies were very analogous, differences were found in the manner and approach to the implementation of educational technology. The pedagogical considerations for e-learning uptake in both universities corroborated with each other to a certain extent. The findings further showed that most of the educational factors that affect technology integration, and subsequent educational technology adoption, resonate with pedagogical issues found in other developing countries.

Global competition, societal changes and other environmental influences have forced organisations to review existing work arrangements. Flexible work practices have been identified as one mechanism for the alignment of organisational and individual goals. Homebased work or telecommuting, which involves working at a remote site, is an example of such a practice. Working from home can have advantages for the organisation in terms of savings in infrastructure costs. Individual employees would also potentially benefit through reduced costs associated with work (e.g. travel and food), and the ability to better manage their work and home life. However, since 25 years ago when home based work was starting to be recognised as a viable work option, projections for homebased work have not come to fruition. Much of this is attributed to conservative organisational cultures, specifically managerial resistance towards work at home. The relatively small amount of research on homebased work has to some extent perpetuated management uncertainty in Australia and overseas. This study aimed to examine the attributes needed by homebased workers, that is, the personal and job characteristics that could make the arrangement successful in both individual and organisational terms. This knowledge would lessen management uncertainty in relation to the types of jobs and employees who could be deemed suitable to engage in this new work practice. The study was exploratory in nature. Information was collected from human resource managers at 472 organisations in Australia. This was followed by semi-structured interviews with 21 homeworkers. Based on the literature, and information collected through the first two phases of the study, a questionnaire was designed to collect more specific information from homeworkers, and clarify points of interest. All up 42 responses were received from this phase of the study. This study was cross-sectional in nature, however, the three-phased approach allowed for cross validation of results, and was therefore very valuable in detecting trends. Findings from this research indicated that personal characteristics, such as demography, competencies, and the psychological profile of the homeworker, do contribute to the benefits gained from the program. Job characteristics, in terms of occupation and the design of the job to be performed at home, also contribute to success. Although, the main focus of this study was on personal and job characteristics deemed suitable for homebased work, it was also found that the home and work environment of the homeworker are major success factors. It can therefore be surmised that benefits from a homebased work program can be enhanced by selecting for appropriate employees and jobs, and devising policies that account for the home and work environment of the homeworker.

Thesis (DTech (Information Technology))--Cape Peninsula University of Technology, 2018.
Although the use of mobile technology features prominently in all walks of life, learning and teaching supported by its ad hoc use in higher education contexts is an under-researched topic. Moreover, elements constituting best practices for quality improvement and aimed at informing decision-making stakeholders, are spread across disparate frameworks, reported in literature. The study aimed to meet the following objectives: • O1: To identify the elements that inform strategic decisions for ad hoc mobile technology-enhanced learning. • O2: To inform the structure of the framework, defined by its constituent components. These objectives were associated with two main research questions, addressed via five secondary research questions that guided the exploration of elements associated with the ad hoc use of mobile technology-enhanced learning in a specific higher education environment. The study consequently proposed a consolidated and synthesised set of theoretically based and empirically determined elements, leading to a framework of interrelated guidelines. A moderate constructionist approach adapted from Järvensivu and Törnroos (2010) underpins the dual-purpose research design. At first, a systematic literature review explored existing frameworks applicable to e-learning, m-learning, technology-enhanced learning and blended-learning modalities. The review was subsequently expanded to include additional sources that addressed diverse aspects of mobile technology-enhanced learning. I undertook an extensive qualitative data analysis of the 55 articles resulting from the systematic literature review. Analysis techniques incorporated open, axial and selective coding, memoing, thematic analysis and the construction of network maps using ATLAS.ti V8.0, a CAQDAS tool. Outcomes of the analysis established an initial set of theoretically grounded elements, comprising a hierarchy of 11 constructs, five categories, 16 sub-categories and 60 items. Network maps demonstrated the interlinking of elements for each of the five categories titled: A. Enablement, B. Environment, C. Interactivity, D. Dynamics and E. Mobility. A final network map consolidated these individual maps, presenting the foundations for a framework for the ad hoc use of mobile technology-enhanced learning in higher education contexts. The theoretically based elements established foundations for the empirical portion of the study – a single exploratory case study defined by an architectural technology domain. The case study supported the inclusion of multiple perspectives and complex, natural contexts where mobile technology usage by stakeholders was the focus of the study. Empirical data was collected during six studies from purposively selected faculty respondents. Qualitative data analysis of collected data yielded additional empirically determined elements namely: eight constructs, eight sub-categories and 35 items. These empirically determined elements augmented findings of the systematic literature review. Additional categories did not emerge; however support for theoretically based elements was demonstrated via network maps.

Many of the models for the adoption and integration of ICT in higher education are situated within an institutional framework. These models can be viewed as supplementary discourses in the meta-narrative of educational change theory. Thus concerns about the process of adoption and implementation in Higher Education can be subsumed under the bigger topic of education change.

This research is part of the Graduate Studies in Education: Curriculum of PUC-SP, on the New Technology in Education line. The research aimed to answer the following question: How does the process of integrating technology into the curriculum occur in a context where: a) there is access to technological resources; b) the teachers take continuing education development for the pedagogical use of digital information and communication technologies (DICT), and c) the school allows for the implementation time prescribed in the literature to introduce technology for transformational pedagogical work? With this background, the general objective of the research consisted of understanding the DICT integration process into the curriculum of a municipal public school in a digital city and to show that such process happens in a spiral-like form. Specifically to characterize the research context; to identify the signs of technology integration into the curriculum through the reading of official documents such as teacher planning and lesson plans and the school's Political-Pedagogical Project and Action Plan; to identify, document and analyze the processes of use of technology linked to the school's activities by routine observation; to understand instances that suggest how the school understands the pedagogical use of DICT; and to offer the school teacher development focused on the use of technology aiming at analyzing the process of its pedagogical use. The theoretical framework was based on the areas of education technology, curriculum theory and the integration of technology into the curriculum. As for the methodology, the research-action resources were used to collect and generate data, such as: in loco direct observation, online questionnaire, individual and collective semi-structured interviews, and professional development for the pedagogical use of DICT. The research participants were teachers, learning mediators and school managers. Data analysis allowed to infer that the process of DICT integration into the curriculum was also a result of the teacher development process offered by the school and the process had characteristics that mirrored to the learning spiral as developed by Valente (2002). Throughout the analyses it was possible to note that the ascendent spiraling movement did not occur; instead, a horizontal spiral in scope and comprehensiveness occurred, followed by a web-shaped movement that emerges from the interaction among individuals mediated by cooperation, interaction and the interdisciplinary work at the school. This research shows that knowledge sharing promotes both teachers’ growth in the process of pedagogical appropriation of technology, and integration of technology into the curriculum
A presente pesquisa insere-se no Programa de Pós-graduação em Educação: Currículo da PUC-SP, na linha de pesquisa Novas Tecnologias em Educação. A investigação pretendeu responder à questão: Como acontece o processo de integração de tecnologias ao currículo em um contexto onde há acesso aos recursos tecnológicos, os professores passam por formação continuada para uso pedagógico das Tecnologias Digitais de Informação e Comunicação (TDIC) e a escola tem o tempo de implantação de tecnologias indicado pela bibliografia como importante para a transformação do trabalho pedagógico? Nesse sentido, o objetivo geral constituiu em compreender o processo de integração das TDIC ao currículo em uma escola pública municipal de uma cidade digital e mostrar que esse processo ocorre de forma espiralada. Especificamente, caracterizar o contexto da pesquisa; identificar indícios de integração de tecnologias ao currículo por meio da leitura dos documentos formais, como: planejamentos e planos de aulas dos professores, Projeto Político-Pedagógico (PPP) e Plano de Ações da escola; identificar, documentar e analisar os processos de uso de tecnologias vinculadas às atividades na escola por meio da observação cotidiana; compreender as manifestações que indicam como a escola entende o uso pedagógico das TDIC; oferecer, na escola, formação para uso de tecnologias, e analisar o processo de sua utilização pedagógica. O referencial teórico foi encontrado nas áreas de tecnologias na educação, teoria de currículo e integração de tecnologias ao currículo. Como metodologia, foi utilizada a pesquisa-ação, lançando mão de diversos instrumentos para levantamento e geração de dados, como: observação direta in loco; aplicação de questionário on-line; entrevistas semiestruturadas individuais e coletivas; e formação para uso pedagógico de TDIC; considerando como participantes da pesquisa professores, mediadores de aprendizagem e gestores da escola. A análise dos dados permitiu inferir que o processo de integração de TDIC ao currículo é fruto também da formação oferecida na escola e apresentou características que o aproximam do modelo teórico de espiral da aprendizagem proposto por Valente (2002). Durante as análises, foi possível notar que o movimento espiralado ascendente ocorreu, porém mais horizontal, em abrangência e amplitude, acompanhado por um movimento reticular, que emerge da interação entre os indivíduos mediados pela cooperação, interação e pelas possibilidades de trabalho interdisciplinar na escola. A presente pesquisa aponta que é no compartilhamento de conhecimentos que pode haver tanto o crescimento dos professores no processo de apropriação pedagógica de tecnologias como também a integração de tecnologias ao currículo

The purpose of this study was to investigate the relationship between twenty-first century instructional methods and student learning experiences. To do so, a typical and representative group of eight students was selected for qualitative interviews which ascertained student perception of their engagement in a typical New Media class. The study determined the perceived impact of a "student-centered instructional approach to video creation" on levels of student engagement in order to understand the nature of engagement and how they moved towards higher levels of independent learning. Transcripts of these interviews were used to identify a thematic structure of student perceptions of their engagement in a classroom where a "student-centered instruction approach to video creation" was used. Lastly, using the teacher's professional reflections, notes, and anecdotal reports from the class, students' stories of engagement were created to illustrate each unique journey toward self-engaged independence from the teacher's perspective. The results of this data pointed to three meta-themes. Meta-theme 1: Positive Relationships and Affective Climate, Meta-theme 2: Personalized, Student-centered Supported Independence, and Meta-theme 3: Accelerated Lift and Independent Learning.

In the face of the extensive changes resulting from the Post-Industrial Age, many are questioning "the gifts of the chip," or, more specifically, the ability of computer technologies to deliver the comfort predicted. The objective of this thesis is to examine the law's response to computer technology concerning occupational health and safety. This inquiry is necessary due to the dramatic changes that have occurred in the workforce, altering the profile of workplace health.
The thesis begins with a reference to The Gift of Stones, a fictional account of the difficulties that stone workers experienced when the Bronze Age arrived. Modern labourers face parallel struggles due to the arrival of the Post-Industrial Age characterized by technological innovation and restructuring. The legitimacy and effectiveness of occupational health and safety law is challenged by changes to social institutions and by computer related work injuries.
In many jurisdictions, the state has responded to these changes by enacting ergonomic standards that seek to minimize the harmful effects of computer use. The thesis examines the trend towards ergonomic standards with particular focus on Canadian initiatives. In conclusion, it argues that ergonomic regulations are an important means of promoting safer computer practices. Additionally, ergonomic standards provide a mechanism for continued state regulation of occupational health and safety. The challenge for rule makers is ensuring that the standards are a component of comprehensive legal reforms.

Thesis submitted in fulfilment of the requirements for the degree Doctor of Technology: Design in the Faculty of Informatics and Design at the Cape Peninsula University of Technology
Design education has been fundamentally changed by computers and new digital technologies. New ideas and new frontiers have emerged. Available literature shows ICT has revolutionalised design education through the online studio and blended learning. In response to the growing needs of ICT in design education, new courses are being designed, while collaborations on design projects are emerging owing to virtual design studios (VDS). Researchers in design, especially in professional architecture and engineering, believe that ICTs enhance the teaching and learning of design. The adoption of ICT at the various stages of problem solving has not yet been reflected in the teaching of graphic design, especially in idea development. In developing economies, in the recent past, more attention has been paid to graphic design pedagogy, as it particularly relates to using ICT in ideation. Using the ‘multi-method’ approach, the research captured both quantitative and qualitative approaches in a pragmatic paradigm. It explored how ICT has affected the teaching and learning of ideation in graphic design in a university in a developing country. This included investigating pedagogical models and paradigms that had informed graphic design education since the incorporation of ICT. It surveyed ICT methods and the players involved in graphic design education, and documented the everyday experiences of students and educators in the lecture rooms to obtain a more holistic impression of teaching and learning. Empirical evidence suggests considerable access to computer and ICT methods by students especially. Various perceptions on the use of ICT by students in ideation activities as far as graphic design education is concerned, and how ICT is informing ideation, were also captured through the data. The study revealed activity systems of ICT integration as something that created contradictions. The contradictions were characterised by activities of collaborations and uses of ICT by students on one hand, and lecturers on the other hand. There were significant revelations of the development of the graphic design processes of using ICT in ideation. Ultimately, they were revelations of complexity of the design process for which there were no precise and fixed formulas that bring together form, function, and context conditions, and which gave credence to the orientation of pragmatism in terms of epistemology to which the study ascribed from the beginning. The study therefore elicits a review of the pedagogy of graphic design, with constructivism becoming relevant in the teaching of ideation in graphic design education.

ENGLISH ABSTRACT: In this dissertation I report on an action research study in relation to the democratisation of science education in a Grade 10 life sciences classroom at a local high school through the application of educational technology, more specifically social network media such as Facebook. I argue that action research for social justice with the support of educational technology can contribute towards cultivating critical teaching and learning in the science classroom, thus contributing to the democratisation of science education in schools. In the main, this study shows that educational technology can contribute to the democratisation of science education in classrooms in relation to teaching contentious issues in the current life sciences school curriculum on three levels: firstly, learners and educators can experience enhanced levels of participation, collaboration and deliberation through Facebook; secondly, learners can construct personal learning contexts as a testament to the sense of autonomy they have (and can acquire) in learning about life sciences, particularly as they endeavour to nurture their critical and problem-solving skills, construct and apply life sciences knowledge, and integrate understandings of life sciences into the context of societal change; and thirdly, learners and educators can cultivate equal partnerships in the sense that equality refers to their insistence to „rupture‟ and „disrupt‟ pedagogical activities in the life sciences classroom. Finally, this study also reveals that critical teaching and learning in the life sciences classroom cannot be oblivious to poststructuralist thought on learning to think and act rhizomatically as opposed to hierarchically and linearly, and that exercising one‟s individual autonomy through a claim to intellectual equality can simply be pedagogical ingredients that can further enhance democratic science education in schools.
AFRIKAANSE OPSOMMING: In hierdie proefskrif doen ek verslag oor ‟n aksienavorsingstudie in verband met die demokratisering van wetenskaponderwys in ‟n Graad 10 lewenswetenskappe- klaskamer in ‟n plaaslike skool deur die toepassing van onderwystegnologie, meer spesifiek sosiale netwerkmedia soos Facebook. Ek argumenteer dat aksienavorsing vir sosiale geregtigheid met die ondersteuning van onderwystegnologie kan bydra tot die kultivering van kritiese onderrig en leer in die wetenskapklaskamer, wat dus bydra tot die demokratisering van wetenskaponderwys in skole. Hierdie studie bewys hoofsaaklik dat onderwystegnologie op drie vlakke kan bydra tot die demokratisering van wetenskaponderwys in klaskamers met verwysing na omstrede vraagstukke in die huidige lewenswetenskappe-skoolkurrikulum: eerstens kan leerders en opvoeders hoë vlakke van deelname, samewerking en beraadslaging deur Facebook ervaar; tweedens kan leerders persoonlike leerkontekste konstrueer as bevestiging van hulle sin van outonomiteit wat hulle bekom (en kan aanleer) deur leer oor die lewenswetenskappe, veral soos hulle poog om kritiese en probleemoplossingsvaardighede uit te bou, wetenskapskennis te konstrueer en toe te pas, en betekenisse van lewenswetenskappe in die konteks van sosiale verandering kan integreer; en derdens kan leerders en opvoeders gelyke verhoudings kweek in soverre gelykheid verwys na hulle aandrang daarop om pedagogiese aktiwiteite in die lewenswetenskappe-klaskamer te „verbreek‟ en te „ontwrig‟. Ten slotte wys hierdie studie dat kritiese onderrig en leer in die lewenswetenskappe-klaskamer nie onbewus kan wees van poststrukturalistiese denke oor die aanleer van risomatiese eerder as hiërargiese en liniêre denke en optrede nie, en dat die uitleef van individuele outonomie deur aanspraak te maak op intellektuele gelykheid die pedagogiese inspuiting kan wees wat benodig word om demokratiese wetenskaponderwys verder in skole te bevorder.

Streszczenie:

In this digital age many listeners of music now purchase albums from online digital music stores instead of buying a physical album from the record store. This has created a concern with many regarding the future of the album as a physical medium. This study investigates the impact of the possible death of the album on certain listening habits, the activity of record collecting, the creation of large-scale musical works, music consumerism, and its implications for the creative process on music as art and sound-recording quality. Three realisations have led to the problem statement. Firstly, the album might not have a future in the digital age. Secondly, downloadable songs might not be able to recreate an album experience. The third realisation is that the possible death of the album could create new, exciting challenges to artists as they strive to create art. This study is exploratory in nature - and no hypothesis was generated. The research necessitates qualitative, exploratory, descriptive and contextual approaches. Furthermore, the investigation has led to the collection of mostly new data, constituting a “primary data design” through the implementation of qualitative listening experiments and a focus group, using full-time NMMU students between 18 and 25 years of age. It is herein argued that digital distribution might possibly have an effect on the perception of the album format and might possibly still be a relevant listening experience, valued by young people. Singles and albums are collectable; and good albums are considered artistic and comparable to the large-scale musical works of the past. If the concept of an album does not die out, then high fidelity formats should be able to re-invent the album experience. Listening experiences other than the album experience do exist, and they could generate new ways for artists to create musical art.

This thesis explored the potential of engaging gifted and talented learners in an online community of inquiry promoted by the use of asynchronous discussion forums. It employed a mixed-method, case-study approach where non-participant observation of online interactions and focus group meetings with the tutors contributed to the qualitative analysis of how the members realised participation in the forums. Quantitative analysis of membership data and online questionnaire responses revealed member characteristics of the sample members and patterns of active (vocal and silent) participation. Analysis was inductive and interpretive, informed by an original synthesis of the theoretical perspectives of two theories: the online learning theory suggested by Garrison, Anderson and Archer (2000); and the cognitive and affective domains for learning skills, proposed by Bloom et al. (1956) and Krathwohl et al. (1964). Content analysis of over 3000 messages posted or read by approximately 4500 members revealed community-based and ability-based characteristics that enabled the group to deal with social stigma, co-construct knowledge and promote meta- learning skills. The study concluded that participation in online discussion forums held the potential to address several of the needs identified by research for gifted learners: The need for the company of like-minded and similar ability peers; the need to develop higher order thinking skills; and the need to become independent learners. In this online network, the gifted learners could receive communal support from other members and tutors who acted as 'mentors' and role models for honing interpersonal and thinking skills such that they were motivated to pursue their interests to their full potential.
