Full textAbstract:
Syftet med denna studie är att undersöka hur föräldrar upplever att deltagandet i en föräldrautbildning har påverkat samspelsförmågan och relationen till sitt/sina barn. Undersökningen vill skapa en förståelse för betydelsen av stöd till föräldrar i form av föräldrautbildningar när det gäller att förhindra utvecklingen och fortgången av riskbeteenden hos barn. Undersökningens övergripande frågeställningar är följande; Hur upplever föräldrar som deltagit i en föräldrautbildning att de samspelar med sina barn?, Har insatsen inneburit några förändringar i jämförelse med hur det såg ut tidigare? samt Vilka nya verktyg och användbara strategier anser föräldrarna att de fått efter genomförd föräldrautbildning? I studien har kvalitativ metod använts. Metodvalet grundas i ambitionen att få en djupare insikt i intervjupersonernas specifika upplevelser och erfarenheter. Undersökningspopulationen utgörs av tre kvinnor som var och en intervjuades under cirka en timmes tid. Urvalskriterierna för undersökningenheterna var att de skulle ha deltagit i föräldraprogrammet COPE. De resultat som framkom tolkades utifrån tidigare forskning samt valda teorier; social inlärningsteori samt systemteori. Samtliga respondenter visade sig ha positiva erfarenheter av COPE, upplevde någon form av förändring i jämförelse med tidigare och ansåg sig ha haft nytta av föräldrautbildningens metoder. Ett övergripande mönster tydde på att föräldrarna upplevde att samspelet med barnen förbättrats, och nämnde då framför allt kommunikationen som den mest utmärkande förändringsfaktorn.

Full textAbstract:
This PhD project studied the caesium and strontium removal capacities of six nanoporous materials. Indeed, it was linked in with the SIXEP plant present at Sellafield site, UK, which is currently using natural clinoptilolite, originally mined from the Mojave Desert, to remove radioactive caesium and strontium ions from wastewater effluents. At the moment the feeds entering the SIXEP plant correspond to the best working conditions for clinoptilolite. As the feeds are moving toward more acidic pH and complex solutions and as clinoptilolite works at neutral pH, new nanoporous materials are required. This project had been divided into sub-projects, which all had the same purpose of finding the best material for caesium and strontium removal under complex solutions. The first part of the PhD focused on the synthesis of CST, SNT, ETS-4 and ETS-10 materials following literature reviews. The two last materials studied were provided by Fortum Power and Heat Oy for CsTreat material and by Sellafield Ltd for clinoptilolite material. The second part of the PhD consisted in studying the exchange capacities for caesium and strontium ions for each material studied under batch conditions using several water compositions relevant to Sellafield Ltd. Each water composition had different competing ions or pH and were used to classify the materials between them. From that it was found that Clinoptilolite stays the best materials for caesium and strontium removal. The third part of the project was the gamma irradiation of the materials. This irradiation had an aim to check the stability of the structure of the studied materials under gamma irradiation. The materials were exposed to four different gamma doses which were 0.5; 1; 3 and 6 MGy, the last one corresponding to the maximum dose were structural changes could happen. This revealed that all the materials, except ETS-4 material, were stable under gamma irradiation and that no structural changes were observable. The fourth part of the project was an extension of the third part in which the materials were Cs exchanged before being gamma irradiated to a dose of 6 MGy. This showed that the caesium exchange process is not affected by radiation. Finally, the unexchanged materials were alpha irradiated using a 15 MeV He2+ beam at the Dalton Cumbria Facility. Two irradiations were performed on CsTreat, CST, ETS-4, ETS-10 and clinoptilolite material. It was found that all the materials were damaged by alpha irradiation and displayed amorphous framework To resume, it appeared that clinoptilolite still stays one of the best materials for the removal of caesium and strontium ions in a wide range of wastewater composition. Additionally, it was discovered that ETS-10 material could be a good alternative to clinoptilolite material as its structure is stable under gamma irradiation and it displayed good exchange capacities when competing ions were present in the feeds. CST could also be a substitute as it shows good ion exchange properties under a broad range of pH. SNT material was great for strontium removal while CsTreat was working well for caesium removal. Even though ETS- 4 revealed good ion exchange capacities they were lower than clinoptilolite, ETS- 10 or CST materials.

Full textAbstract:
Magister Artium - MAAccording to our ordinary conception of voluntary action, our actions are the causal result of conscious intentions. To take a very basic example: I wish to take a sip of coffee, and I therefore reach out and take hold of the mug. However, studies performed by Libet challenge this ordinary conception. What Libet found in his experiments was that the brain initiates voluntary actions and the person becomes consciously aware of an intention to act only some 400 msec after the brain’s initiation; for instance, my brain has already initiated the process of causing my arm to reach out and take hold of the mug some 400 msec before I am aware that I wish to take a sip of coffee. That is, conscious intention doesn’t appear to precede voluntary action at all – it actually follows it (or follows its initiation, at least), and thus Libet’s studies present a serious challenge to our ordinary conception of voluntary action. This project will investigate whether a particular theory of mind – namely, Armstrong’s Central State Materialism – can cope with the challenge posed by Libet’s studies and salvage our ordinary conception of voluntary action. Armstrong’s theory appears promising in this regard because his account of consciousness and introspection as higher-order states seems to allow room that we will become aware of our willings only after those willings are already initiated.

Full textAbstract:
Föreliggande examensarbete avser att studera hur verksamma kursledare inom COPE föräldrastödsprogram redogör för vilken avsikt COPE föräldrastödsprogram har, samt hur de beskriver att de arbetar för att uppnå målsättningarna med föräldrastödsprogrammet. Syftet är även att undersöka om verksamma kursledare inom COPE föräldrastödsprogram upplever sig som experter på föräldraskap. Den metod vi valt att använda är kvalitativ intervju. Det är åtta verksamma kursledare inom COPE som är intervjuade och deras svar som agerar utgångspunkt för studiens resultat. De teorier studien vilar på är social inlärningsteori och empowerment. Studiens resultat visar att COPE föräldrastödsprogram, enligt de verksamma kursledarna, syftar till att hitta verktyg och strategier för föräldrar att hantera vardagliga problem. Vidare är ett av COPE:s syfte att ge föräldrar ett socialt nätverk av likasinnade föräldrar för att öka nätverksbyggandet mellan föräldrar. Det essentiella är att föräldrar får en ökad tilltro till sin egen förmåga i rollen som föräldrar. Detta uppnås genom framförallt gruppdiskussioner vilka förs utifrån olika filmvinjetter som presenteras för föräldrarna och diverse dilemman. Viktigt enligt kursledarna är att alla frågor som ställs i gruppen ”kastas” tillbaka till gruppen för att öka deras egen tilltro till sin förmåga. De verksamma kursledarna upplever sig inte som experter på föräldraskap utan menar att det är föräldrarna själva som är experter på sina barn och därmed sitter på lösningarna. Det framkommer dock att föräldrarna ser kursledarna som just experter på föräldraskap.

Full textAbstract:
Background: Due to constant changes and unpredictability in a turbulent environment, the traditional way of planning does not seem to work anymore. Therefore, new approaches to the external and internal conditions need to develop in order to cope with the environmental turbulence.
Purpose: The purpose of this thesis is to define a turbulent environment and identify how an organisation can cope with this environment. Procedure: We have developed a frame of reference mainly consisting of theories regarding a turbulent environment and change. In addition, we have selected eight guiding factors, which we have used when studying, systemising, and comparing how contemporary literature suggests that an organisation can cope with a turbulent environment.
Results: The conclusions we have come to are that with a definition of the environment as being fast-changing and of chaotic nature, where the changes are continuous, emergent, small, big or somewhere in between, and where paradoxes play an important role, it is necessary to develop an organisational structure, leadership, human resource, and corporate culture, in which the objective always is to create dynamics and to build in an acceptance of change.

Full textAbstract:
The research described in this thesis is aimed at demonstrating the synthetic utility of the asymmetric amino-Cope rearrangement and highlight its potential for future application in natural product synthesis. Using the recently developed asymmetric anionic amino-Cope methodology, rearrangement of diasteromerically pure 3-amino-l,5-hexadiene substrates provided the target aldehyde in good yield and with high levels of asymmetric induction (up to 94% e.e.). The aldehyde obtained was used for the successful formation of2,4-disubstituted lactones with no apparent loss of stereochemical integrity. This could lead to a plausible route to biologically significant compounds.

Full textAbstract:
Consumption of a range of substances has been associated with human coping behaviour. Accordingly, food, caffeine, cigarettes, alcohol and/or other drugs are consumed as a coping strategy, in response to a stressful situation by some individuals. While various perspectives within the field of psychology have examined consumptive coping behaviour, there has been limited exploration of the specific functions that this coping strategy may serve. The primary aim of this research was to explore various functions that consumptive coping serves, via construction of a self-report questionnaire. The relevant literature on coping with stressful events and increased consumption was reviewed and critically examined, as was the current state of self-report measurement of consumptive coping. Subsequently, it was proposed that there is a niche for more thorough research into the perceived utility of this coping strategy. Based on the literature, five functions of consumptive coping were anticipated, namely escape/sooth emotions, physical relief, distraction from thoughts, time-out and self-punishment. Various methods were presented that investigated the phenomenon of consumptive coping, and detailed the construction and refinement of a self-report measure, titled the Consuming to Cope Questionnaire (CCQ)...

Full textAbstract:
Intermolecular reactions are inherently more difficult than intramolecular reactions, and several transformations can only occur as cyclizations, often to form 5-membered rings. The use of directing or tethering groups allowing preassociation with a reagent or catalyst is a common strategy to overcome such low reactivity, which can lead to increases in the rate, regioselectivity and stereoselectivity of intermolecular reactions. Typically, such preassociation involves hydrogen bonds, coordination to a metal ion/catalyst or stepwise installation of a temporary tether. As part of ongoing investigations on metal-free hydroaminations, it was speculated that a simple organic molecule could allow the formation of a temporary tether and enable directed intermolecular Cope-type hydroaminations to proceed at room temperature. Recently, it was found that alkylhydroxylamines add to allylic amines regioselectively in the presence of an aldehyde catalyst. This thesis presents the background material, design elements, optimization and scope of this reactivity.

Full textAbstract:
This study looks at the problems facing students in their University careers and considers how they may be helped and supported at this time. A University Nightline telephone befriending service (LUA-Linha da Universidade de Aveiro) was established in Portugal (where no such provision previously existed) in order to provide a research vehicle for examining these issues, as well as to meet students' needs. The primary focus of the research was on the experiences of the Student Helpers who staffed the Nightline and on the issues presented by their clients. The research method was one of co-operative inquiry.Through the training of Student Helpers and implementation of this service, insight was gained into the nature of students' problems. Consequently, it was possible to produce a taxonomy of student needs. A distinction was drawn between problems relating to 'inter-individual' (individual and academic) life and 'intra-personal' (personal and academic) life, with a course of action relating to each problem area being described as short or long-term. This taxonomy was used to analyse the calls received by the Nightline. Results indicate that most clients were seeking short term solutions to problems relating to 'intra-personal - personal life'. The experiences and problems of Students Helpers were assessed predominantly through the use of questionnaires and focus groups. An unexpected and pleasing outcome from this research was that in providing a peer counselling service, Student Helpers had facilitated their own personal growth. In most respects, their needs paralleled those of the clients they were trying to help.A central tenet of this thesis is that the provision of academic support alone is not sufficient to ensure academic success. The research suggests that greater consideration should be given to opportunities for personal development programs as part of the curriculum in higher education.

Full textAbstract:
Thesis (PhD)--University of Stellenbosch, 2002.ENGLISH ABSTRACT: Suburbanisation is a world-wide phenomenon and is characterised by the decline of central business districts and accelerated growth of commercial activities in the suburbs. The impact of suburbanisation is wide-spread and multi-dimensional, affecting the whole urban system in terms of its structure, activity and transport patterns. In South Africa, suburbanisation, together with the impact of the former group areas policy, has made suburban developments less accessible to the low-income groups living on the edges of the metropolitan area. Planners have proposed various urban densification strategies for the rather unique problems of the spatially inefficient South African cities, including corridor development along main public transport routes and the development of activity nodes. In order to implement these urban densification strategies successfully, it is important to understand the locational choice behaviour of business managers, and the factors that will attract them to locate in a certain area. This will enable metropolitan authorities to evaluate and implement the best policies to promote development of priority corridors and nodes The research for this dissertation was motivated by the extensive problems of suburbanisation, the lack of knowledge on the relative impact of land-use transport factors on the locational choices of businesses, and the apparent limited application of stated preference (SP) survey techniques and discrete choice models to spatial choices of businesses for urban planning purposes. The main objectives of the research were to determine the locational choice behaviour of retail businesses in strategic spatial terms, and how this knowledge can best be used to manage suburbanisation. The dissertation reviews intemational and South African studies on the planning and policies of the main role players in the urban system relating to retail suburbanisation, i.e. the planning authority, retail firms and consumers. The dissertation discusses the results of the market research that was done among Cape Town retailers located in the CSO, and in low- and high-income suburbs. The survey collected quantitative information regarding the locational choice factors of retail managers, importance ratings of choice factors as well as stated preferences for CSO and suburban locations. The calibration results of various discrete locational choice models are discussed, including elasticities of choice factors obtained from model applications to the SP data. The development of a spreadsheet locational choice model based on typical characteristics of CSO and suburban locations is subsequently discussed. Elasticities of choice factors from the application of the spreadsheet model were determined and the model was also used to test a decentralisation trend scenario and a managed suburbanisation scenario. The dissertation makes conclusions and recommendations regarding the most important locational choice factors of retail managers, and the most effective policies and strategies for metropolitan authorities to manage suburbanisation and promote urban densification. The performance of SP models applied to spatial choices are also evaluated and recommendations are made regarding their application and further research needs.
AFRIKAANSE OPSOMMING: Stedelike desentralisasie is 'n wêreldwye verskynsel wat gekenmerk word deur die verval van sentrale sakegebiede (SSG) en die snelle groei van handelsbedrywighede in voorstede. Die impak van desentralisasie is verreikend en multi-dimensioneel en beïnvloed die hele stadstelsel in terme van sy struktuur, aktiwiteite and reispatrone. In Suid Afrika het desentralisasie saam met die impak van die voormalige groepsgebiedebeleid voorstedelike ontwikkelings minder toeganklik gemaak vir die lae-inkomstegroepe wat op die rand van die metropolitaanse gebiede woon. Beplanners het verskeie stadsverdigtingstrategieë, insluitende korridorontwikkeling langs hoofvervoerroetes en die ontwikkeling van aktiwiteitsnodusse voorgestelom die unieke probleme van die ruimtelik ondoeltreffende Suid-Afrikaanse stede die hoof te bied. Om hierdie stadsverdigtingstrategieë suksesvol te implementeer, is dit egter belangrik om die liggingskeusegedrag van besigheidsbestuurders, sowel as die faktore wat hulle beweeg om hulle in 'n spesifieke gebied te vestig, te verstaan. Hierdie kennnis sal metropolitaanse owerhede in staat stelom beleid te evalueer en die beste beleidsopsies te implementeer om die ontwikkeling van voorkeurkorridors en nodusse te bevorder. Die navorsing vir hierdie verhandeling is gemotiveer deur die omvattende probleme wat deur stedelike desentralisasie veroorsaak word, die gebrek aan kennis oor die relatiewe impak van grondgebruik-vervoerfaktore op die liggingskeuse van besighede, en die klaarblyklik beperkte toepassing van verklaardevoorkeuropnametegnieke (V V) en diskrete-keusemodelle op die liggingskeuses van besighede vir stadsbeplanningsdoeleindes. Die hoofdoelstellings van die navorsing was om die liggingskeusegedrag van kleinhandelbesighede in strategiese ruimtelike terme te bepaal en vas te stel hoe hierdie kennis gebruik kan word om stedelike desentralisasie te bestuur. In hierdie verhandeling word 'n oorsig gegee van die internasionale en Suid- Afrikaanse studies oor die beplanning en beleid van die belangrikste rolspelers in the stadstelsel wat desentralisasie van kleinhandel betref, naamlik die beplanningsowerheid, kleinhandelfirmas en verbruikers. Die resultate van marknavorsing onder kleinhandelaars vanuit Kaapstad se SSG en lae- en hoë-inkomstevoorstede, word bespreek. Die opname het kwantitatiewe inligting oor die liggingskeusefaktore van kleinhandelaars, die belangrikheid wat hulle aan keusefaktore heg, en hulle verklaarde voorkeure ten opsigte van vestiging in die SSG of die voorstede, ingesamel. Die kalibrasieresultate van verskeie diskretekeusemodelle word bespreek, insluitende die elastisiteite van keusefaktore wat deur die toepassing van die modelop V V-data verkry is. Vervolgens word die ontwikkeling van 'n liggingskeusemodel in 'n spreitabel wat op tipiese kenmerke van SSG- en voorstedelike liggings gebaseer is, bespreek. Elastisteite van die liggingsfaktore is bepaal deur die toepassing van die spreitabelmodel, en die model is ook gebruik om 'n desentraliasietendensscenario en 'n bestuurdedesentralisasiescenario te toets. Ten slotte word daar gevolgtrekkings en aanbevelings gemaak oor die belangrikste liggingskeusefaktore van kleinhandelaars, en die mees effektiewe beleidsopsies en strategieë wat metropolitaanse owerhede kan volg om stedelike desentralisasie te bestuur en stadsverdigting te bevorder. Die werkverrigting van V V-modelle wanneer dit op die liggingskeuse van besighede toegepas word, word ook geëvalueer en aanbevelings word gemaak oor die toepassing daarvan en verdere navorsing wat nodig is

Full textAbstract:
A dissertation submitted to Departamento de Engenharia Electrotécnica of Faculdade de Ciências e Tecnologia of Universidade Nova de Lisboa in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Engenharia Electrotécnica e de ComputadoresModern broadband wireless systems require high throughputs and can also have very high Quality-of-Service (QoS) requirements, namely small error rates and short delays. A high spectral efficiency is needed to meet these requirements. Lost packets, either due to errors or collisions, are usually discarded and need to be retransmitted, leading to performance degradation. An alternative to simple retransmission that can improve both power and spectral efficiency is to combine the signals associated to different transmission attempts. This thesis analyses two time diversity approaches to cope with lost packets that are relatively similar at physical layer but handle different packet loss causes. The first is a lowcomplexity Diversity-Combining (DC) Automatic Repeat reQuest (ARQ) scheme employed in a Time Division Multiple Access (TDMA) architecture, adapted for channels dedicated to a single user. The second is a Network-assisted Diversity Multiple Access (NDMA) scheme, which is a multi-packet detection approach able to separate multiple mobile terminals transmitting simultaneously in one slot using temporal diversity. This thesis combines these techniques with Single Carrier with Frequency Division Equalizer (SC-FDE) systems, which are widely recognized as the best candidates for the uplink of future broadband wireless systems. It proposes a new NDMA scheme capable of handling more Mobile Terminals (MTs) than the user separation capacity of the receiver. This thesis also proposes a set of analytical tools that can be used to analyse and optimize the use of these two systems. These tools are then employed to compare both approaches in terms of error rate, throughput and delay performances, and taking the implementation complexity into consideration. Finally, it is shown that both approaches represent viable solutions for future broadband wireless communications complementing each other.

Full textAbstract:
This work documents the personal life and contextual events surrounding an ordinary man in order to investigate the history of his development and education both as a person and as a politician. While there are substantial biographical works tracing the life of a politician, few have used oral history to write the life of ordinary politicians from working class backgrounds. Other issues discussed in relation to the work and central to the understanding of the subject are the choice of subject for biography, humour as power, gender dynamics in politics, and life history methodology. The major source of data is interviews, supported by other accounts including newspapers, biographies, autobiographies, Hansard material and archives. The subject's development and education began well within a supportive family environment and continued with a sound formal education at kindergarten, primary and secondary levels. Sport provided a basis for success and self esteem during his schooling and thereafter throughout his life. Post school development was maintained by a self-motivated drive to accumulate knowledge primarily through reading and observation of other people. His likeable personality, natural charm and wit allowed him to connect with excellent role models from whom he continued to learn throughout his union and political careers. Apart from the negative experiences of the Depression, successes throughout life allowed him to endure with dignity and stoicism any setbacks, especially his forced resignation from the position of Speaker, which was devastating and effectively ended his career.

Dentre os estudos sobre características reprodutivas de lagartos, muitos são realizados com espécies de regiões temperadas. Diferentes fatores podem influenciar no ciclo reprodutivo das espécies de lagartos neotropicais como umidade, temperatura e pluviosidade, sendo este último determinante em regiões tropicais. Estudos sobre a biologia reprodutiva de lagartos do gênero Mabuya revelaram características peculiares da reprodução e da história de vida; com isso pode ser considerado um táxon modelo para estudos sobre a evolução dos padrões reprodutivos em vertebrados. As espécies Notomabuya frenata e Aspronema dorsivittatum, apesar de apresentarem alguns aspectos reprodutivos conhecidos, muitas de suas características ainda são desconhecidas. Nesse contexto, o objetivo do presente estudo foi caracterizar morfohistologicamente o segmento sexual renal (SSR) e a espermatogênese de N. frenata e A. dorsivittatum. Os espécimes utilizados neste estudo foram coletados em uma área do bioma Cerrado no estado de Minas Gerais, Brasil. Os rins foram analisados através de microscopia de luz e eletrônica de varredura; e os testículos apenas com microscopia de luz. Ao analisar os rins, constatou-se a presença do SSR apenas em machos sexualmente maduros. O SSR se apresentou revestido por células colunares altas, com núcleo basal e a porção apical repleta de grânulos secretores; tais características morfo-histológicas observadas em ambas as espécies são similares as observadas em outros estudos com diferentes espécies de Squamata. Os testículos foram processados de acordo com técnicas de histologia convencional e analisados por microscopia de luz. Todos os espécimes machos adultos analisados estavam em período reprodutivo, pois apresentavam espermatozoides nos testículos e/ou epidídimos. O epitélio germinativo de ambas as espécies era composto por células germinativas e células de Sertoli, x apresentando um ciclo reprodutivo contínuo. O epidídimo das espécies estudadas apresentouse revestido por epitélio colunar simples, com células altas, núcleos basais e o lúmen completamente preenchido por espermatozoides. Os espécimes de N. frenata e A. dorsivittatum analisadas apresentaram o epitélio germinativo organizado de forma similar a outros Squamatas anteriormente estudados. Existem poucos estudos que abordem a descrição morfo-histológica do segmento sexual renal, células germinativas e espermatogênese de lagartos brasileiros. Dessa forma, o presente estudo acrescenta, não somente o conhecimento sobre a biologia reprodutiva nessas espécies, mas auxilia numa maior compreensão sobre estratégia e biologia reprodutivas em espécies vivíparas e neotropicais.
Among the studies on the reproductive characteristics of lizards, many are carried out with species of temperate regions. Different factors may influence the reproductive cycle of neotropical lizard species such as humidity, temperature and rainfall, being the latter determinant in tropical regions. Studies on the reproductive biology of lizards of the genus Mabuya revealed peculiar characteristics of the reproduction and the history of life; with this it can be considered a model taxon for studies on the evolution of the reproductive patterns in vertebrates. The species Notomabuya frenata and Aspronema dorsivittatum, although presenting some known reproductive aspects, many of its characteristics are still unknown. In this context, the objective of the present study was to characterize the morphologically the sexual segment of the kidney (SSK) and the spermatogenesis of N. frenata and A. dorsivittatum. The specimens used in this study were collected in an area of the Cerrado biome in the state of Minas Gerais, Brazil. The kidneys were analyzed by light microscopy and scanning electron microscopy; and the testis only with light microscopy. When analyzing the kidneys, the presence of SSK was only found in sexually mature males. The SSK was coated by high columnar cells with basal nucleus and the apical portion filled with secretory granules; Such morpho-histological characteristics observed in both species are similar to those observed in other studies with different Squamata species. The testes were processed according to standard histology techniques and analyzed by light microscopy. All the adult male specimens analyzed were in the reproductive period, as they had spermatozoa in the testis and / or epididymis. The germinal epithelium of both species was composed of germ cells and Sertoli cells, presenting a continuous reproductive cycle. The epididymis of the species studied was coated by simple xii columnar epithelium, with high cells, basal nucleus and the lumen completely filled by spermatozoa. The specimens of N. frenata and A. dorsivittatum analyzed presented the germinative epithelium organized in a similar way to other Squamata previously studied. There are few studies that address the morpho-histological description of the renal sexual segment, germ cells and spermatogenesis of Brazilian lizards. Thus, the present study not only adds knowledge about reproductive biology in these species, but also aids in a better understanding of reproductive strategy and biology in viviparous and neotropical species.

COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIORA percepção da imensa exclusão existente no Brasil motivou o surgimento, dentro do Movimento dos Focolares, da Economia de Comunhão - a qual é uma proposta que visa amenizar a situação de necessidade e miséria enfrentada por certas parcelas da população de todo o mundo. A questão colocada nesta dissertação é se essa iniciativa é, de fato, capaz de contribuir para o enfrentamento da exclusão social, ainda que localmente. Para tentar respondê-la, estudou-se o caso do município de Vargem Grande Paulista, uma vez que ali nasceu a Economia de Comunhão. Foi, então, construído um quadro conceitual de referência, baseado, principalmente, na obra de Norbert Elias e John L. Scotson intitulada Os Estabelecidos e os Outsiders. Este foi utilizado para interpretar a realidade observada na comunidade e nas empresas de Economia de Comunhão. Aqueles autores demonstram que a exclusão, além da dimensão material, tem uma importante dimensão simbólica. A partir da observação tanto das intenções originais associadas à idéia de uma economia baseada na partilha quanto da conduta das pessoas envolvidas, conclui-se que a Economia de Comunhão tem potencial para enfrentar a dimensão simbólica da exclusão. Resta saber se tal projeto crescerá o suficiente para atingir uma massa crítica capaz de fazer com que os resultados se reflitam em indicadores macro- econômicos e sociais.
The exclusion that exists in Brasil has motivated the emergence of the Economy of Communion from within Focolari Movement. That is a project that aims at relieving the situation of necessity and misery that certain parts of world population deal with. The question that is focused in this dissertation is if such project is capable of contributing to cope with social exclusion, even locally. In order to answer it, the case of Vargem Grande Paulista was studied, since it was the place where the Economy of Communion was born. Then, a conceptual framework was built based on the book of Norbert Elias e John L. Scotson: The Established and the Outsiders. It was used to interpret the reality observed at the community and among the Economy of Communion companies. Those authors show that exclusion has both a material and a symbolic dimension. Based on the original intentions associated with the idea of a economy of sharing and also on the observations on individual`s behavior, it is concluded that the Economy of Communion has potential to cope with the symbolic dimension of exclusion. However, another question remains to be answered: will it grow enough to a critical mass capable of making the results perceivable at macro economic and social indicators?

Ferguson, Heather. "How do male military veterans cope with psychological difficulties?" Thesis, University of Liverpool, 2015. http://livrepository.liverpool.ac.uk/2034899/.
Full textAbstract:
This thesis consists of three sections: a systematic review, an empirical paper and the appendices, which are intended to support the empirical paper. The two papers are intended for publication in different journals and are written in the style required by those journals. Thesis Overview In the UK, a military veteran is defined by the government as anyone who has served in the armed forces for at least one day; they will simply be referred to as veterans from here on. The mental health of veterans is very much in the public awareness, especially due to the recent conflicts in Iraq and Afghanistan. Research dedicated to this area has mostly used quantitative methodologies, focused on Post-traumatic stress disorder and has been conducted in the United States. The research, and the media, has a tendency to give a more negative overview of veteran’s mental health, and their health outcomes, by emphasising such difficulties as substance misuse and offending behaviour. Therefore the aim of this thesis was to start to fill in the gaps. This was achieved by reviewing and adopting qualitative methodologies and involving British veterans. The research aimed to explore the possibility of positive change after military service, and veterans own views on how they experience and cope with psychological difficulties. By knowing more about veterans’ experiences, from veterans’ themselves, we will be more able to inform services and tailor the support to improve their outcomes and enhance their well-being. The term Post-traumatic growth (PTG) is relatively new, but the concept of growth out of adversity dates back to at least the 1960s. PTG was introduced by Tedeschi and Calhoun to describe positive psychological change resulting from experiencing traumatic events. It is conceptualised as a long-term coping strategy for ongoing stress following adversity (Tedeschi & Calhoun, 2004). Positive growth has been indicated in the experiences of people after a range of traumatic events but the types and levels of trauma experienced by military personnel are unique. This is because they may endure multiple and chronic trauma, they have voluntarily put themselves in harm’s way and they could experience combat exposure both as victim and perpetrator (Linley & Joseph, 2004; Larner & Blow, 2011; Larner, 2013). Research suggesting that veterans can experience PTG has tended to focus on quantitative aspects of prevalence and influential factors, with no qualitative review of how veterans actually experience PTG. Chapter one of this thesis is a systematic review of the qualitative literature exploring veterans’ subjective experiences of PTG after military service. It aims to highlight those areas more prone to growth and to help inform interventions that may facilitate this process. To enable us to inform interventions to promote positive change, it is important to know how veterans are coping with psychological difficulties from their own perspective. Chapter two of this thesis is an empirical study that explored the way veterans from the North West of England, who had accessed a veterans’ psychology service, are coping with psychological difficulties. Q Methodology (Stephenson, 1935) was used to provide a systematic and non-threatening way to collect a large range of subjective viewpoints. The paper discusses the clinical implications of the findings and recommendations for future research within the context of the strengths and limitations of the study. It is hoped the findings will increase the awareness of this complex area, highlight the need for more research and aid the development of more targeted interventions focused on those more adaptive and growth promoting coping processes.

Full textAbstract:
Syfte: Efter att ha bedrivit föräldrautbildning enligt COPE-modellen (The Community Parent Education Program) under cirka fem år på en BUP-mottagning ställdes frågan av verksamhetens chef om man bör fortsätta med COPE-föräldrautbildning på BUP–mottagningen eller om man skall gå över till annan typ av föräldrautbildning. En utvärdering gjordes därför av den COPE-föräldrautbildning man bedrivit på BUP-mottagningen. Frågeställning var: ger COPE -föräldrautbildning enligt föräldrarna själva ökade färdigheter för att de ska kunna agera på ett mer funktionellt sätt mot sina barn? Metod: Man valde att intervjua föräldrar som gått någon av de två senaste föräldrautbildningarna eftersom man tänkte att de hade utbildningen mer aktuell och därför lättare skulle kunna besvara frågor om utbildningen. Ett halvstrukturerat frågeformulär utarbetades utifrån tidigare kursutvärderingar och användes som intervjustöd. Sammantaget sju föräldrar av tjugo intervjuades per telefon sedan uppnåddes mättnad. Resultat: Föräldrarna var nöjda med den föräldrautbildning de gått och barnen hade utvecklats positivt. Föräldrarna tyckte att de lärt sig nya strategier och att de blivit bättre som föräldrar. Det bästa med utbildningen enligt föräldrarna, var att de fått träffa andra föräldrar i samma situation eftersom de tidigare känt sig ensamma med sitt problem. Några föräldrar önskade att ledarna styrde hemuppgifterna mer men några tyckte att det var bra som det var.

Full textAbstract:
Nitrogen-containing molecules are ubiquitous in both natural products and pharmaceutical drugs, thus an efficient method for the formation of these motifs is of great importance. Hydroamination, that is the addition of an N-H bond across an unsaturated carbon-carbon bond of an alkene or alkyne, stands out as a potential approach to obtain such molecules. To date, most research in this area relies on transition-metal catalysis to enable such reactivity. In efforts directed towards metal-free alternatives, we have developed a simple, metal-free hydroamination of alkenes using hydrazides. Further investigation into the corresponding reactivity of alkynes with hydrazides has provided access to novel azomethine imine products. In Chapter 2, expansion of the substrate scope with respect to the intramolecular hydroamination of alkenes using hydrazides, as well as studies directed towards elucidation of the mechanism of this reaction will be presented. The intramolecular hydroamination of alkynes using hydrazides and methods to access and isolate the azomethine imine products formed will be discussed in Chapter 3.

Full textAbstract:
The anionic amino-Cope rearrangement is currently being developed by our group as a new synthetic protocol. Our ultimate goal is the one-pot asymmetric synthesis of compounds such as (A), with up to 3 contiguous chiral centres, via an amino-Cope rearrangement and subsequent enamine derivatisation and hydrolysis. [Illustration omitted.] The mechanism of the anionic amino-Cope rearrangement is still a matter of debate and we have investigated the effect of solvent and substituents on the enantioselectivity observed in the reaction. The aim of this study was to find the optimal conditions for the anionic amino-Cope rearrangement, eliminating—or at least minimising—competing reaction pathways that can reduce the enantioselectivity of the process. In addition, the aldehyde product of the amino-Cope rearrangement has been used as a chiral building block for the synthesis of heterocycles such as tetrahydropyrans (B) and lactones (D). The synthesis of piperidines (C) has now been achieved, enhancing the scope of this rearrangement.

New Anionic Annulation Reactions and Anion Accelerated Amino-Cope Rearrangement. This dissertation compiles asymmetric anionic reactions of chiral Ellman sulfinyl imines and dienolates to access diverse nitrogen-containing compounds. Chiral sulfinimines and dienolates derived from 𝛾-bromocrotonates reacted diastereoselectively forming 3-pyrrolines and 𝑐𝑖𝑠-vinyl aziridines via a formal [3+2]-annulation and vinylogous 𝑎𝑧𝑎-Darzens reactions respectively. Concise asymmetric syntheses of three natural products have been achieved demonstrating the power of the [3+2]-methodology. Reaction of conjugated sulfinimines with enolates derived from non-halogen containing crotonates, were found to undergo a tandem diastereoselective α,α-addition, and anionic [3,3]-rearrangement affording vinylogous amide products. Synthesis of aromatic imines via 2,3-dichloro-5,6-dicyanobenzoquinone (DDQ) initiated oxidative aromatization highlights the synthetic value of the accelerated anion amino-Cope rearrangement.

Full textAbstract:
In Hong Kong, little is known on the role of government retraining in helping older and low-skilled workers cope with unemployment. The aim of this study is to explore the relationship between Hong Kong's government retraining and psychological well-being among unemployed older and low-skilled trainees, and the effects of demographic factor (age and gender) on coping mechanisms. The results are based on qualitative interviews with 15 Chinese re-employed security guards aged 50+ after participation in the government retraining programme. The results showed that participants used both problem-focused coping (Hong Kong's government retraining) and emotion-focused coping (social support, escape, relaxation and leisure activities). Such retraining helped participants to meet their economic and psychosocial needs, and develop jobs skills for better well-being. Participants tended to be self-reliant and to rely on financial support from family members to save face. The results also indicated that men were less likely to use social support than women to share their emotional distress with others, and relied more on relaxation and leisure activities. The lower educated tended to take part in less social leisure activities than the better educated to regulate stress, and preferred relaxation activities at home. Following re-employment, the better educated felt more underemployed than the lower educated, whereas those in former high-status jobs used higher-level self-categorisation than those in former low-status jobs as a way to escape from their low-status security job. Overall, the findings show that features from the theories of Jahoda (1982), Fryer (1986) and Warr (1987) relate to well-being, and demographic factors (age, gender and education) and cultural factors (face-saving and self-reliance) affect coping mechanisms. These findings implicate the need to adjust the existing theoretical framework to be appropriate for Hong Kong Chinese society and to offer practical implications for policy and practice in the areas of retraining policy, gendered labour market, unemployment benefits, age-friendly working environments, retraining programmes and career counselling service aiming to enhance well-being and facilitate work re-entry of older workers.

Full textAbstract:
Gender bias may cause organizations to lose the values that women bring to the workplace in leadership positions and may thwart women from reaching their personal goals. The purpose of this qualitative descriptive multiple case study was to explore gender bias and its influence on women on corporate boards, their roles, appointment, and the need to develop coping strategies to deal with gender bias to execute their roles. The conceptual lens used was Tajfel and Turner's social identity theory to explain the basis for intergroup discrimination, and Eagly and Karau's role congruity theory of prejudice to explain the exclusion of women from corporate boards as a result of gender bias. The research question focused on identifying gender bias and experiences of women on a corporate board. Social media and snowball sampling were used to recruit 6 English-speaking women on corporate boards who had experienced gender bias at the time of their appointment and in their roles on corporate boards in the public and private sectors in provinces and territories throughout Canada. Data sources included interviews, journaling, and analysis of physical artifacts such as government reports and databases of women on corporate boards. Using Yin's 5 phases of analysis, the study identified 7 emergent themes in the data sources: discrimination, harassment, organizational climate, well-being, disruption, empowerment, and leading. The study's potential for positive social change resides within its potential to promote the internal transformation of women as they deal with bias. Men also need an improved understanding of their perceptions of women in the governance structures of society to help reduce gender bias toward women.

Full textAbstract:
Crop water requirements are important elements for food production, especially in arid and semiarid regions. These regions are experience increasing population growth and less water for agriculture, which amplifies the need for more efficient irrigation. Improved water use efficiency is needed to produce more food while conserving water as a limited natural resource.
Evaporation (E) from bare soil and Transpiration (T) from plants is considered a critical part of the global water cycle and, in recent decades, climate change could lead to increased E and T. Because energy is required to break hydrogen bonds and vaporize water, water and energy balances are closely connected. The soil water balance is also linked with water vapour losses to evapotranspiration (ET) that are dependent mainly on energy balance at the Earth’s surface.
This work addresses the role of evapotranspiration for water use efficiency by developing a mathematical model that improves the accuracy of crop evapotranspiration calculation; accounting for the effects of weather conditions, e.g., wind speed and humidity, on crop coefficients, which relates crop evapotranspiration to reference evapotranspiration.
The ability to partition ET into Evaporation and Transpiration components will help irrigation managers to find ways to improve water use efficiency by decreasing the ratio of evaporation to transpiration. The developed crop coefficient model will improve both irrigation scheduling and water resources planning in response to future climate change, which can improve world food production and water use efficiency in agriculture.

Full textAbstract:
This research analyses how two social housing providers in South Africa Johannesburg Housing Company and COPE transferred knowledge from two social housing organisations in Europe - Notting Hill Housing Trust in England and Norske Boligbyggelags Landsforbund also known as the Norwegian Federation of Cooperative Housing Associations (NBBL) in Norway. Following the knowledge transfer, Johannesburg Housing Company has gone on to become a successful organisation while COPE closed down in 2005. This research analyses the knowledge transfer and the dominant organisational learning culture in the two organisations to try and explain why COPE closed down and why Johannesburg Housing Company has succeeded. This research uses knowledge transfer ideas that are within the broader knowledge management field and ideas on organisational learning culture to develop an analytical framework. The framework identifies three key areas for analysis, these are, analysis of the mechanisms used for the knowledge transfer process, the messages that were transferred during this process and analysis and identification ofthe dominant learning culture in each organisation. The main method for the data gathering and analysis was done through interviews with key actors in the four organisations - Johannesburg Housing Company, COPE, Notting Hill Housing Trust and NBBL. Analysis of key relevant documentation was also carried out. It was possible from the findings of the research to conclude that having a successful process ofknowledge transfer does not necessarily translate into success for the knowledge importing organisation. Secondly, that the dominant organisational learning culture in an organisation can have an impact on whether the outcome ofthe knowledge transfer process will be successful or not.

Full textAbstract:
The importance of passion increases with the extent of sorrow. While money can replace the passion by offering the opportunity to buy the added value for oneself and the society, social enterprises, artists and start-up organizations have bigger issues to organize the necessary resources. Passion is inevitable for making a difference in the society while suffering a lack of money. Thus, the presence of a certain obsession is a favorable situation for smaller organizations in order to go through difficulties. This thesis investigates the miracle of passion in order to gain an understanding about the ability of leading passionate people. Theories and experiences from passionate individuals are combined in this research paper and suggest different perspectives a leader must consider by leading passion. I assume the social interaction between leaders and followers which result in a mutual influence of behavior and performance. This thesis is focused on the perspective of passionate followership and elucidates factors that are needed to act passionate as well as the role of the leader within this passionate environment.

Full textAbstract:
The purpose of this study was to elicit information about the process of coping employed by battered women during a hypothetical abusive incident. The research question addressed in this study was: How do appraisal of an event, the use of coping resources, and coping strategies vary across three phases of a single stressful incident?Four variables were examined as group tendencies to react and changes over three phases of a hypothetical abusive incident. These variables were: 1) reported emotions, 2) extent to which the participants felt they could alter the situations (perceived control), 3) use of social support and 4) ways of coping at each stage. In addition, individual differences in coping as a function of emotions experienced, feelings of control and use of social support were also examined. The participants in this study were 54 females who had been admitted to a shelter for battered women. An experimental, repeated measures design was employed and data was analyzed using multivariate analysis of variance and linear, stepwise regression analysis. All hypotheses were tested at alpha = .05.The results of this study showed that emotions, perceptions of control and coping strategies significantly changed across the three phases of the abusive incident. There were significant main effects found for emotions, perceptions of control and types of social support used, regardless of the phase of the incident. In addition individual differences in coping as a function of cognitive appraisal variables were also found. This study shows that a stressful encounter i s a dynamic, unfolding process and riot a static unitary event. As the abusive incident proceeded from the anticipation stage to the outcome stage, there were concomitant changes in emotions, appraisals of control over the situation and coping strategies used. This study also showed that people cope in complex ways and that problem-focused coping was combined with emotion-focused coping at each stage of the encounter.
