Full textAlzheimer’s disease (AD) is pathologically characterized by amyloid beta (Aβ) depositions and hyperphosphorylated tau. A disintegrin and metalloproteinase 10 (ADAM10), is responsible for the α-secretase cleavage of Amyloid Precursor Protein (APP), that prevents Aβ generation. The synaptic localization and its activity towards APP are modulated by protein partners, which interact with the cytoplasmic tail of ADAM10. Considering this, we performed a two-hybrid screening that identified actin-binding protein “cyclase-associated protein 2” (CAP2) as a novel binding partner of ADAM10. CAPs are implicated in actin cytoskeleton remodelling and vesicle trafficking of non-neuronal cells, and microarray analysis of AD patient hippocampi specimens revealed a down-regulation of CAP2 in AD patients. Therefore, the aim of this project is to evaluate the role of the ADAM10/CAP2/actin complex in the amyloid cascade and in AD-related synaptic dysfunction. The main results of the project indicate that: - CAP2 is self-aggregating and interacts with both actin and ADAM10. - In the hippocampus of CAP2 knockout mice the synaptic levels of ADAM10 and of the NMDA receptor subunit GluN2A are significantly reduced, suggesting that the lack of CAP2 affects their localization. In particular, the CAP2/actin complex is essential for ADAM10 synaptic localization since it is involved in ADAM10 endocytosis. Additionally, we detect an altered spine density and morphology in hippocampal neurons of CAP2 knockout mice, and they show elevated levels of the toxic Aβ1-42 in their hippocampus. These data indicate the relevance of CAP2 in synaptic function and structural plasticity. - Regarding AD, a reduction in CAP2 protein levels and in its synaptic localization is detected in the hippocampi of AD patients and AD mice. In addition, alterations in the association of CAP2 to actin and ADAM10 are found. - CAP2 has a role in activity-dependent synaptic plasticity mediated by long-term potentiation, and in aberrant plasticity triggered by Aβ oligomers, which regulate CAP2 synaptic localization and association to its binding partners. In light of these results, we designed two potential therapeutic approaches to tackle the CAP2 pathological pathway in AD. First, we overexpressed CAP2 in an in vitro system modeling AD, and we found an increase in ADAM10 synaptic levels after overexpression of CAP2. Secondly, since the CAP2-actin complex is increased in AD pathogenesis and this complex seems to be important for ADAM10 synaptic localization, we designed a cell-permeable peptide (CPP) to interfere with the CAP2-actin association. The interference by the CPP treatment can affect ADAM10 synaptic levels and increases its activity towards APP. Overall these data indicate that CAP2 is a potential pharmacological target to increase ADAM10 synaptic localization as a novel AD therapeutic strategy.

Full textSince the dawn of democracy, the South African government has set up different measures to improve education in schools, inter alia the provision of funding, resources, feeding schemes and the introduction and amendment to different curricula. The current education policy, the Curriculum and Assessment Policy Statement (CAPS), was adopted in 2012 following three other consecutive education policies that had not delivered to the desired standard in terms of educational outcome. This study focuses on the perceptions of teachers in terms of their freedom to pursue the aims of CAPS in low-income school communities. The teachers' perceptions and freedoms were explored and analyzed using the Capabilities Approach (CA) authored by Amartya Sen which forefronts the capabilities (the ability to achieve) and the functionings (real achievements). Teachers' perceptions were therefore explored and analyzed in terms of freedoms and unfreedoms they enjoy and face in the process of transferring the knowledge to learners. The thesis studied and analyzed the capabilities and perceptions of teachers in terms of their real freedoms through the deconstruction of their experiences.

Full textThis study focuses on progress monitoring regarding CVC (consonant-vowel-consonant) words with three first grade students. The aim of this project is to find the most appropriate frequency of assessment in progress monitoring of first grade students who receive Tier 2 response to intervention for consonant vowel consonant words over a three-month period. Three students were chosen to participate in Response to Intervention (RTI) for literacy. These students received twenty minutes of RTI instruction four days a week. Response to Intervention is a process used by educators to help students who are struggling with a skill or lesson. These three students needed additional instruction with consonant vowel consonant (CVC) words. Each of the three students were progress monitored and assessed either twice a week, once a week, or biweekly. Data was collected on each student to show progress during the three-month period. The purpose of this study is to learn which frequency of progress monitoring is appropriate for students to gain progress over a length of time when receiving RTI instruction.

Full textIn South Africa, demographics consequently play a prominent role in public policy and the country (rainbow nation) or often called a World in One Country, provide interesting interactions between the whites, coloured and blacks. South Africa remains the highest-ranked country in sub-Saharan Africa and the second-placed among the BRICS economies. Furthermore, the country benefits from the large size of its economy, particularly by regional standards, but the profile of various immigrant groups is poorly understood, thereby creating ambivalence in policy frameworks. A, major weakness of research in this area has been the tendency to study causes and impacts of migration separately, which constitute largely separate strands of migration literature. More in general, the scholarly debate has tended to separate the determinants and impacts of migration artificially from more general processes of socioeconomic contexts. Thus, there is a clear need to study migrant profiles in their wider societal context, which makes this study contemporaneous. Our research profiles both the demographics and socioeconomic dynamics of the French immigrants in South Africa on one hand and highlights the differences between French emigrants in Western Cape, South Africa and their counterparts residing in France vis-à-vis South Africans in Western Cape. In determining, the effect of socioeconomic and demographic profiles of the French immigrants in the Western Cape, a Google web design was used. Prior to this, a pilot study using samples of French and Anglophones persons was done to validate the instrument. Two questionnaires were used for the study; one in English and the other in French. Likert scales, multiple choice, open ended and close ended questions were contained in our instrument. Only registered households with French Consulate were included in the population sample. The population of South Africans is much younger than that of the French in Western Cape or French in France. The latter group is ageing but lives longer than the South Africans because of advancement in health infrastructure. Thus, the French community in the Western Cape are better placed economically, socially, and health-wise compared to the South Africans (WC) and the French in France. However, in few areas like education, rent and medical insurance coverage, the French in France are better placed than the French and South Africans in the Western Cape, because of structural issues peculiar in a country like South Africa. These social issues in France have more optimality than in South Africa. Our results further confirm the validity of the New Economics of Labour Migration Theory, which recognises the role of households as against individuals in jointly making the decision to migrate. Migration of a household member is a way to spread the risk of insufficient household income. Nonetheless, the survey indicates that the Western Cape is a city of choice for French migrants. However, a comparative analysis of the influx of the French to other regions would further show the real reasons for French deciding to pitch tent in a particular region. Analysis suggests an imbalance in the labour supply of the French immigrants which could be a structural phenomenon akin to also to the South Africans themselves. Enlightenment programmes for the target population and host population could help in this regard to balance the labour mix. There is no doubt that the socioeconomic impact of migration has been intensively studied by scholars, but it is still often driven by ill-informed opinions, which, in turn, can lead to public resentment towards migration. This is exactly the case for South Africa that has witnessed rounds of xenophobic attacks on migrants. These negative assessments risk on-going efforts to adapt migration policies to the new economic and demographic challenges facing many countries. Results confirm that labour supply becomes the pull factor for the French immigrants. Furthermore, it is likely that the bureaucratic set up at the Home Affairs is still inhibiting the French Immigrants from processing their documentation. On the average, it takes about 2 to 3 years to process legal permit documents for foreigners in South Africa. This process could be discouraging others from migrating to South Africa. Also, the xenophobic syndrome and inconsistent policy framework could also be a deterrent to foreigners who genuinely want to reside on a permanent basis in the country. The development potential of migrants is not expressed to its fullest extent, partly because of the lack of migration-supporting policies, which pushes many migrants to illegality despite the demand for their labour in certain sectors. Being undocumented not only encourages exploitation in the workplace but also prevents migrants from contributing to the development of the host country by paying taxes. A step in the right direction would be to encourage government service providers to mainstream migration into policies and programmes. This would set the framework for greater respect for migrants' rights, as well as facilitate the integration of migrants and acknowledge their contribution to the development of host and home countries.

Full textThis thesis is the first book-length description of the Portuguese Creole spoken on the island of Fogo (Cape Verde, West-Africa), spoken by most of the 40,000 island’s inhabitants as well as by its diaspora. This work provides an insight on the linguistic structure of this variety, based on data collected during fieldwork occurred between 2016 and 2019. This study comprises with nine chapters, namely (1) introduction, (2) phonology, (3) syllabic structure, (4), stress, (5) nominal morphology, (6) verbal morphology, (7) syntax, (8) lexical peculiarities and (9) conclusion.This thesis brings new elements both to the synchronic and diachronic analysis of Cape Verdean Creole. At the same time, it contributes with comparative data for the reconstruction of the Upper Guinea Portuguese Creole (UGPC) language family. These data show in particular that Fogo Cape Verdean emerged quite early as a distinct variety among UGPCs and illustrate the main characteristics of this variety.This thesis also provides historical data on the discovery, settlement, trade connections, maritime interactions, social structure and sociolinguistics of the island of Fogo, and shows the role played by these elements in the development and shaping of Fogo’s unique linguistic makeup

Full textA K foi uma revista publicada em Portugal, entre 1990 e 1993, com a direcção de Miguel Esteves Cardoso. Fruto de um encontro de gerações e de quadros de referências com interesses diversificados, a revista foi expressão editorial de uma elite cultural que introduziu um discurso livre e diferenciado na imprensa periódica da época. Com um grafismo elegante e arrojado, da autoria de João Botelho e Luís Miguel Castro, a K distinguiu-se como um objecto editorial sofisticado e bem impresso. Esta investigação tem como objectivo realizar o estudo da K, no âmbito da história do design editorial produzido em Portugal, no início da década de 90, enquanto expressão visual de uma manifestação cultural geralmente designada como “pós-modernismo”. A filiação da K no universo do pós-moderno no design gráfico deve-se ao facto de a revista ter sido fruto da sua época, sendo concebida a partir de outras publicações que, por sua vez, materializavam visualmente esta tendência. Como tal, esta perspectiva temática fornece uma interpretação da revista num contexto mais amplo do que o português. A temática do design gráfico no pós-modernismo é convocada a partir de vários contributos bibliográficos, os quais nos fornecem as linhas de orientação seguidas na interpretação da revista. O estudo procede ao levantamento exaustivo de todas as edições da K, sendo aí aferidos os seus atributos gráficos e editoriais. As publicações que a antecederam são também integradas na investigação, revelando uma rede complexa de autores, de referências gráficas e editoriais que estão presentes na sua genealogia. A recolha de testemunhos dos intervenientes na K colmata a ausência de bibliografia sobre a revista e suas antecedentes. O design editorial da K fica caracterizado pela exploração de recursos formais e técnicos heterogéneos. Desse modo, esta publicação distanciava-se criticamente do despojamento formal e da busca de coerência típicos do modernismo internacionalista, que dominara as décadas anteriores enquanto modelo de referência. Manifestou-se na importância atribuída à dimensão estética, na autonomia crescente dos designers na interpretação visual dos textos, na liberdade com que decidiam alguns títulos e, finalmente, no modo como se estabelecia a interacção entre imagem e texto.
ABSTRACT: K was a magazine published in Portugal between 1990 and 1993, under the direction of Miguel Esteves Cardoso. The result of a meeting of generations and reference frame with diversified interests, the magazine was the editorial expression of a cultural elite which introduced a free and differentiated speech in the periodical press of the time. With an elegant and bold graphics, by João Botelho and Luis Miguel Castro, K distinguished itself as a sophisticated and well printed editorial object. This research aims to conduct the study of K within the history of editorial design produced in Portugal in the early 90s, as a visual expression of a cultural event commonly referred to as “postmodernism”. The affiliation of the K in postmodern graphic design is due to the fact that the magazine was a product of its time, being designed from other publications, which, in turn, visually materialized this trend. As such, this thematic perspective provides an interpretation of the magazine in a broader context than the Portuguese. The theme of graphic design in postmodernism is summoned from several bibliographic contributions, which provide us with the guidelines followed in the interpretation of the magazine. The study proceeds to the exhaustive survey of all editions of K, and then measured their graphics and editorial attributes. The publications that preceded the magazine are also integrated in survey, revealing a complex network of authors, of graphic and editorial references, that are present in its genealogy. The collection of testimonies of those involved in K fills the lack of literature about the magazine and its background. The editorial design of the K magazine is characterized by the exploration of heterogeneous formal and technical resources. Thus, this critically distanced the publication of formal simplicity and the search for typical consistency of internationalist modernism, which dominated the previous decades as a reference model. Expressed on the importance attributed to the aesthetic dimension, on increasing autonomy of the designers in the visual interpretation of the texts, the freedom with which decided a few titles and, finally, in the way they established the interaction between image and text.

Full textENGLISH ABSTRACT: This study aims to reconstruct the history of the Capetonian theatrical venue of the second half of the 19th century. It explores the many different venues used for theatrical activities. Venues discussed include amateur theatres such as the Hope Street Theatre, Roeland Street Theatre, Haupt's Theatre and the Drury Lane Theatre. Due to the extensive research already done on the African Theatre on Riebeeck Square and the Garrison Theatre they are only briefly mentioned as part of the background to the social dynamics of Victorian Cape Town. Quite often venues such as banqueting halls, drawing-rooms and wine stores doubled as theatrical venues. Halls discussed include the Oddfellows Hall, the Mutual Hall and the Drill Hall. Although the main objective of the study was the theatrical venue, it is impossible not to mention the different drama companies that occupied these venues. Therefore, the activities of the drama companies were also discussed to a certain extent, because of the strong interrelationship between company and theatre house. These include, among others, the companies of Sefton Parry and Disney Roebuck. For the purpose of this study the theatrical venue has been defined as an indoors space, which is divided into two clearly demarcated areas, namely the stage and the auditorium. Because of this definition the early African theatrical activities are not included in this study and it deals rather with the Western theatre tradition, namely that of the early Dutch and English artists. The study deals primarily with the dominant English theatre post-1850 and the shift from amateur to professional theatricals. Professional theatres include the Theatre Royals of Harrington Street and Burg Street, the Exhibition Theatre and the Good Hope Theatre. At the end of the thesis parallels are drawn between the 19th and 20th century theatre houses such as the Opera House and the Tivoli Theatre. Another issue addressed by the study is the quest for a permanent theatrical venue or building in the early Cape theatre tradition.
AFRIKAANSE OPSOMMING: Die studie poog om die geskiedenis van die Kaapse teaters te herstruktureer. Dit ondersoek die verskillende plekke en geboue wat vir teater aktiwiteite gebruik is gedurende die tweede helfte van die 19de eeu. Amateur teaters wat bespreek word is onder andere, die Hoopstraat Teater, die Roelandstraat Teater, Haupt se Teater en die Drury Lane Teater. Die Afrika Teater op Riebeeck Plein en die Garnisoen Teater vorm nie deel van hierdie studie nie, aangesien daar alreeds heelwat oor hierdie twee teaters geskryf is. Daar word slegs kortliks in die Inleiding na hulle verwys in die agtergrond tot Kaapstad gedurende die Victoriaanse tydperk. Dramas is nie net in formele teaters aangebied nie, maar ook in verskeie informele plekke soos banketsale en dies meer. Sale wat gebruik is vir sulke doeleindes was onder meer die Oddfellows Saal en die Mutual Saal. Alhoewel die hoof oogmerk van die studie die vermaaklikheidsplek (theatrical venue) is, sou dit onvoldoende wees om nie die verskillende drama geselskappe te noem wat in hierdie plekke opgetree het nie. Daarom is die aktiwiteite van die geselskappe ook bespreek na gelang van hul betrokkenheid by spesifieke teaters, onder andere die van Sefton Parry, James Lycett en Disney Roebuck. Die vermaaklikheidsplek word vir die doeleindes van hierdie studie gedefinieer as 'n binnehuise spasie wat verdeel word in twee duidelik afgebakende areas, naamlik die speelarea en die ouditorium. Die definisie hou egter sekere beperkinge in: Dit sluit die vroee inheemse Afrika teater aktiwiteite uit. Gevolglik word die vroee Westerse teater tradisie van die Hollanders en die Engelse bespreek. Die studie fokus hoofsaaklik op die meer dominante Engelse teater gedurende die tweede helfte van die 19de eeu, en die oorskakeling van amateur na professionele drama. Professionele teaters wat bespreek word is die Theatre Royals (Harrington Straat en Burg Straat), die Exhibition Teater en die Goeie Hoop Teater. Aan die einde van die tesis word daar 'n vergelyking getref tussen die 19de en 20ste eeuse teaters, soos byvoorbeeld die Operahuis (1893) en die Tivoli Teater (1903). Nog 'n aspek wat aangespreek word is die soeke na 'n permanente teatergebou binne die vroee Kaapse teater tradisie.

Full textEsta tesis constituye una mejora sustancial en el conocimiento sobre la ecología de los cetáceos al sur de la península ibérica que permitirá desarrollar estrategias de conservación más adecuadas para este grupo de especies. Pudimos definir diferentes unidades de manejo ecológico de delfines mulares a través de un enfoque multidisciplinar (Capítulo 3) que permitirán la implementación de estrategias de conservación específicas para cada unidad. Por primera vez determinamos la dieta de los delfines mulares del Golfo de Cádiz (Capítulo 4) así como la de los delfines comunes del Estrecho de Gibraltar y el Mar de Alborán (Capítulo 6). Con esta información, evaluamos el consumo de presas por los delfines comunes en el Mar de Alborán (Capítulo 6), destacando la potencial competencia con las pesquerías locales. Para la correcta conservación de la amenazada subpoblación de delfines comunes del Mar de Alborán se propusieron nuevas áreas marinas protegidas junto con una estrategia basada en combatir las amenazas a nivel de cuenca (Capítulo 7). Además, esta tesis reveló que las especies de cetáceos pueden dividir su nicho trófico y espacial para permitir la coexistencia (Capítulo 5). Asimismo, proporcionamos valores esenciales para la reconstrucción de la dieta de cetáceos a través del análisis de isótopos estables que se pueden utilizar a nivel mundial para una correcta evaluación de las presas asimiladas (Capítulo 1). Paralelamente hacemos disponible una gran cantidad de regresiones entre el tamaño del otolito y el tamaño del pez que nos permite reconstruir la longitud de las presas ingeridas por los cetáceos (Capítulo 2). Esta información no tan solo es útil para la reconstrucción de la dieta ingerida por cetáceos sino que es extremadamente útil para el estudio de la dieta de otros depredadores. En general, la importancia de esta tesis reside principalmente en proporcionar información clave para mejorar las estrategias de conservación de los cetáceos al sur de la península Ibérica, pero también dicha información es aplicable a otras zonas de estudio. Este es un importante paso adelante en el estudio de la ecología y la conservación de los cetáceos y, al mismo tiempo, abre nuevas preguntas por resolver.

Full textAmb l'objectiu de millorar l'estat de conservació dels mars europeus, es va adoptar la Directiva Marc de l'Estratègia Marina (MSFD) l'any 2008, que estableix un marc general per a tots els països de la UE en l'àmbit de la política ambiental marina. La MSFD demana a tots els Estats Membres que adoptin una estratègia de gestió adaptativa en les seves aigües territorials basada en (1) una gestió ecosistèmica, (2) la creació i gestió d'àrees marines protegides (AMP) com a eines imprescindibles per assolir un (3) un bon estat ambiental, al qual han d'evolucionar com a resultat de (4) mesures de gestió que només s'aplicaran després de la posada en marxa d'un (5) programa de seguiment basat en (6) indicadors seleccionats prèviament. En el cas de l'Estat espanyol, la MSFD es va transposar jurídicament com una llei estatal l'any 2010, conduint cap a la designació de 10 noves AMP mar endins. Una d'aquestes 10 àrees, avaluada en el marc del projecte Life+ Indemares, estableix els límits territorials d'aquesta tesi doctoral: l'àrea marina del Cap de Creus. Aquesta tesi comença avaluant l'estructura de les comunitats de fauna invertebrada presents a la plataforma continental i el canó submarí en base a 60 transectes de vídeo submarins. Les imatges van permetre identificar fins a 167 espècies, que formen un total de 9 comunitats bentòniques diferents. La fondària, la velocitat de la corrent i el tipus de substrat es van identificar com els factors principals que determinen els patrons espacials observats a l'escala de l'àrea d'estudi, tot i que la intensitat de la pesca juga un paper preponderant en les zones de fons tou de la plataforma. Aquesta informació es va utilitzar per elaborar mapes de distribució predictius de comunitats usant l'algoritme Random Forest. Altes intensitats de pesca d'arrossegament tenen un impacte negatiu en la riquesa, la diversitat i també en l'estructura de les comunitats a la plataforma continental. A partir de la resposta a nivells creixents d'esforç pesquer de diferents espècies clau de la megafauna, es van triar 4 espècies com a indicadors per a un programa de seguiment. La tesi proporciona un protocol de seguiment detallat, conjuntament amb dades de base quantitatives, per així poder avaluar l'evolució futura de l'ecosistema bentònic una vegada que es posin en pràctica les mesures de gestió. El protocol proposat descriu la metodologia de mostreig que s'ha d'emprar al mar, l'anàlisi de les imatges de vídeo, el tractament de les dades i la interpretació dels resultats. Es van identificar també dues comunitats de peixos a les imatges de vídeo, però el reduït nombre d’individus que s’observen ens fa ser molt pessimistes amb el seu ús com a indicadors de l'activitat pesquera en el protocol de seguiment. Finalment, aquesta tesi proporciona també la quantitat d'escombraries marines acumulades al fons marí de l'àrea d'estudi.

Full textThis thesis investigates the digitalization and financialization of the housing market in Cape Town, South Africa. Borrowing from economic sociology and urban geography, I develop the concept of "housing market assemblage" to both analyze and conceptualize how the evolution of market structures renews contemporary patterns of social stratification and urban segregation in an emerging global city. To do so, I use mixed methods that combine qualitative and quantitative approaches. Over 18 months of fieldwork, I conducted interviews with market professionals (real estate agents, property developers, mortgage brokers, bankers, investors) and households, while engaged in participant observation of a local estate agency in Cape Town's largest black township (Khayelitsha). Furthermore, I built a database of 900,000 residential real estate transactions and employed multivariate statistics and spatial analysis to track the evolution of prices and mortgages across the post-apartheid urban space. The thesis demonstrates how the housing market was reconfigured as a continuous flow of data through the adoption of digital platforms and the progressive making of housing as a financial asset on both the buyer's and rental markets. The market creates two filtering mechanisms with deep stratifying effects : (i) housing affordability is determined by the unequal spatial distribution of housing prices, on the one hand, and the social and racialized distribution of income and family assets, on the other, in a context of highly selective lending practises (ii) the hegemonic use of credit scoring technologies that allow the automated classification of South African citizens through an information dragnet of unprecedented sophistication and depth, both for the Global North and the Global South. Banks and newly formed corporate landlords use credit scoring to classify & select mortgage recipients and tenants, in a context of household indebtedness and enduring racial inequalities. The housing market operates therefore as a spatial economy of classification, whereby individuals, properties and neighborhoods are valued and classified according to profit and risk factors. Focusing on the market allows to engage more fully, but think beyond, prevailing concerns of the "post-apartheid" city: the spatial distribution of credit thus constitutes the main contemporary factor for both understanding and mapping the evolution of enduring inequalities and residential structures in the emerging South African city. In order to conceptualize this form of market stratification, I define the new middle class as a "filtered class", and processes of global urban integration through the ordering of financialized and digitalized housing market assemblages that both engender new urban forms and renew social-class patterns across the emerging city

Full textDetta examensarbete sammanställer och tar fram information om en typ av fäste som kallas “Trunnion cap” som används på några av de truckar och lastare som utvecklas på Atlas Copco Rock Drills AB i Örebro. Informationen behövs för att skapa en konstruktionsriktlinje för trunnion caps. Arbetet är begränsat till att undersöka de trunnion caps som används vid infästning av styrcylindrar på sex olika fordon, MT436B, MT5020, MT6020, ST1030, ST14 och ST1520. Det undersöker från vilka vinklar kraften som genereras av styrcylindern verkar från. Dessa vinklar verkar inom ett intervall från 6 till 96 grader. Själva kraften har också beräknats med avseende på maximalt styrtryck vilket varierar från 21,5 till 30 MPa beroende på fordon. Värdefull information från kunder har också eftersökts delvis genom att fråga anställda vid några av Atlas Copcos marknadsbolag runt om i världen om de är medvetna om några tillfällen då trunnion caps eller bultar till trunnion caps har havererat. Svaren på denna fråga tyder på att inga problem existerar idag men att de problem som funnits tidigare berott på bristande service. Även Atlas Copcos interna databaser för servicerapporter har genomsökts på rapporter som rör delar till trunnion caps, dock utan att någon relevant information hittats. Examensarbetet har även sammanställt de toleranser som hålen i trunnion caps:en samt axeln som monteras dit har. Resultatet varierar då några sammanställningar har greppassning medan andra har spelpassning. Slutligen har även tillgängligheten på bult med hållfasthetsklass 8.8 och 10.9 undersökts där det har noterats att ledtiden för bult med hållfasthetsklass 8.8 i allmänhet är kortare än för bultar med hållfasthetsklass 10.9.

Similarly, in 1841 Joseph Paxton designed a glass conservatory at Chatsworth for the tropical Victoria regia water lily, which literally referenced the lily pad veins as structural system. This preoccupation with nature as a design generator continues in the 20th century with digital tools that derive architectural form using biomimicry, in the work of R & Sie. All these projects are based on a dialectic relationship between architecture and nature, where the particular model of nature is translated into form. This relationship in landscape architecture is discussed through the idea of the biomorphic. Applied as a guiding principle to investigate vegetation and plant form in the 17th Century Company’s Gardens arguing that the generation of the biomorphic can be adjusted to serve as a mechanism to understand plant form in terms of effect.

Full textWomen, being important stakeholders of the community, are lagging behind in terms of economic empowerment. Their opportunity to participate actively in business in the past was hindered by various discriminatory policies that were in place. ICTs have the forte to empower and increase the knowledge base of the women in SMEs through information dissemination. The argument is that women in South Africa and indeed in many other developing countries have not embraced technology in their everyday businesses as much as their male counterparts. This study therefore explores how women in SMEs in the Cape Metropolitan, Western Cape are utilising ICTs to empower themselves to overcome the economic discrimination they have suffered in the past.In order to collect relevant data and obtain deep insights about the utilisation of ICTs by women in SMEs, a qualitative research method was applied enabling respondents to articulate their experiences concerning the use of ICTs in their businesses. Women of all races were selected using the snowball sampling method and were interviewed. The population involved women in SMEs from the five suburbs of Claremont, Rondebosch, Gardens, Pinelands and Mowbray.The findings of the study are that women in SMEs in the Cape Metropole are utilising various ICTs to empower themselves in their businesses. They are exchanging business documentation with other business resulting in marketing of their entities. Women in SMEs are taking advantage of the fast growing social and business networking technologies such Facebook, LinkedIn, Flickr, Twitter, Skype and blogs to promote marketing of their various products and services, gaining mileage in publicity and also managing their expenditures.ICTs enable women to work anytime, anywhere affording them the opportunity to take care of their families which they could not do while they were employed in the corporate world. Some of the women in SMEs reported that they can now independently negotiate business deals due to increase in their self-esteem and also have access to available information in their areas of expertise.

Full textThis study aimed to ascertain in what ways violence and crime influence the teaching and learning programme in schools in a disadvantaged community. The context is a primary school in an informal settlement in Samora Machel, Philippi, in the Cape Flats, where violence is endemic. The study shows that violence does not occur in school playgrounds and areas around the school only; classrooms are becoming common sites for violence. This study sought to establish teacher and learner experiences of violence at school, and the role of school management and parents in dealing with it, with a specific focus on school policies on discipline and how violence affects teaching and learning. The investigation also included learner behaviour during recess.

L'hypothèse de base est qu´on est dans un pays où les autochtones ont toujours vécu avec des étrangers, pas dans leur pays d´origine, mais dans des nombreuses destinations d'émigration. De même, cette coexistence, que fut la plupart du temps avec les Européens et les Américains blancs, commence à s´établir avec les voisins du continent, non pas dans un pays tiers mais au Cap Vert. Par conséquent, l'objectif est de comprendre les relations entre les groupes sociaux, nationaux et immigrés, à la suite de la fixation et l'insertion des immigrés dans les secteurs socio-économiques nationaux, particulièrement dans le marché du travail, où on trouve un taux de chômage élevé.
Cette étude est fondée sur un dialogue avec les théories des migrations internationales et les théories des représentations sociales et qui soutiennent la thèse.
From a country of emigrants, Cape Verde transformed into a country of immigrants during the 90’s, mainly in the second half of that decade. The country started receiving immigrants especially from the neighbourhood countries of the ECOWAS region, due to the free movement of people subscribed in the Protocol of movement of people ratified by Cape Verde. The country has been a focus of attraction of labour workers following the boom in tourism and related activities, including construction and public works, commerce, hotels, and restaurants services.
This work has the main objective to analyse the construction of the images of the people coming from the ECOWAS countries members in Cape Verde, the representations and reciprocal attitudes in relation to this phenomenon and the contexts in which they occur. It is assumed that we are in a country where the local population always interacted with foreigners not in their origins but in the various migratory destinations. Similarly, this coexistence that happened mainly with white Europeans and Americans is happening with the neighbours of the continent. Consequently, it is intended to understand the relationships the social groups, nationals and immigrants establish among them as a result of establishment and insertion in the national socioeconomic sectors, mainly at the labour market, where, along with high unemployment rate, it is, verified a massive inclusion of the ECOWAS foreigners.
The current study is based on a dialogue with the international migration theories and the social representation theories that will support the thesis.

He inherited this story, a diglossic situationwhere Portuguese is the official language while Creole, now called « Cape Verdean language », -born of Luso-African language contacts – is the vehicle of everyday expression. The history of CapeVerdean society is also rooted in that of emigration and national and international mobility. If weatherconditions have prompted many Cape Verdean to exile, both in Africa than in Europe or the UnitedStates, structural handicaps have also favored the constant migrations of islanders worldwide.Through surveys conducted both in Cape Verde and France, are studied differences in languageproficiency between Cape Verdean who acquired their languages in each of these countries. Theanalysis is based primarily on their personal journeys and pays particular attention to the forms ofbilingualism of each other. The study, which focuses at first on Creole, Portuguese and French,include spontaneous and induced oral productions, and written productions, which are indicative oforal proficiency

Full textCapital Asset Pricing Model (CAPM) är den prissättningsmodell som mest frekvent används av aktörer på den finansiella marknaden samt i litteratur för att förklara sambandet mellan risk och förväntad avkastning. Teorin grundades under 1960-talet av William Sharpe och tidiga empiriska tester av modellen visade att den med hög förklaringsgrad kunde estimera en framtida förväntad avkastning givet en viss risknivå. På senare år har dock CAPM fått stark kritik eftersom nya empiriska undersökningar demonstrerat att modellen inte längre verkar visa en rättvisande avkastning i förhållande till risk.
För att undersöka om den över 40 år gamla modellen fortfarande visar någorlunda rättvisande beskrivningar av verkligheten har vi ställt oss frågan: Går det att med hjälp av historiska data förutspå en riskfylld tillgångs avkastning på den svenska aktiemarknaden?
Vid besvarade av denna fråga har studien syftet Att med hjälp av portföljer studera huruvida sambandet mellan risk och avkastning, vilket postuleras av CAPM, stämmer på den nutida svenska aktiemarknaden.
Vi har utifrån vår kunskapssyn kritisk rationalism använt oss av en kvantitativ metod för att försöka ge svar på problemställningen, vilken angreps med ett deduktivt tillvägagångssätt. Den teoretiska referensramen behandlar teorier som portföljval, den effektiva marknadshypotesen och CAPM. Det empiriska materialet består av historiska aktiekurser vilka bearbetades och användes till att komponera flertalet portföljer. Dessa portföljer har sedan analyserats genom regressionsanalys och jämförts med ett aktiemarknadsindex i syfte att besvara vår problemställning.
Det som framkommit genom studien är att det till viss del med hjälp av historiska data går att förutspå en riskfylld tillgångs avkastning på den svenska aktiemarknaden. Även om vi delvis kan ge stöd åt den testade modellen anser vi inte att betavärdet, som ensamt förklarande variabel och mått på risk, bör tillämpas vid beslutsfattande av investeringar, något som CAPM förutsätter att det ska göra. Det linjära samband som CAPM postulerar bedömer vi vara bristande i tillämpbarhet på dagens komplicerade aktiemarknad eftersom fler variabler än historiska data påverkar aktiekurserna.

Full textThis mini thesis is an exploratory study of the lived experiences of bisexual and lesbian women in the Western Cape with regard to how they claim agency and negotiate their individual sexualities. Using mixed methodologies this study aims to look at the ways in which bisexual and lesbian women negotiate their sexuality in a landscape dominated by heterosexual discourses. Also considered are the contradictory ways in which these women assert their roles as lesbians and bisexual individuals and how these roles serve to simultaneously reinforce and challenge the dominant order of heterosexuality. The conflicting views of the respondents are documented which further demonstrates the complexities surrounding sexuality. This research identifies and explores both international and local research already conducted on alternative sexualities and address the lack of black researchers' conduct of these studies on the African continent. The study also records an acknowledgement of the researcher's reflection that she too holds contradictory views on some of these issues.

Full textIn South Africa today, one of the most urgent economic, social and political challenges is the extraordinarily high and increasing level of unemployment. While the economy has been growing steadily, unemployment levels have continued to rise. A large part of the problem is the fact that the number of new entrant~ outstrips the creation of new jobs (Ashton, 2005; Chichelo et aI., 2003). Since most of the new entrants are people making the transition from school and other education institutions into the labour market, it is not surprising that the problem of unemployment is more severe among the youth. Young people as a group are disproportionately affected by unemployment - whereas the unemployment level for adults is in the region of 26%, the rate for youth is 50%, while 58% of the unemployed are young people (Mlatsheni & Rosphabe, 2002). This paper looks at the factors that affect employment among the youth in the Cape Town area. Using data from the 2002 and 2004 waves of the Cape Area Panel Study, cross-sectional and panel probit regressions have been employed to investigate the role of individual, household and schooling characteristics in the probability of employment. The results suggest that although household income and the presence of employed people in the household were important in a cross-sectional setting, previous labour market experiences were more important in a dynamic setting. While quantity of schooling is found to be very import ant, the impact of quality of schooling could not be determined. The usual race and gender patterns in employment were found.

Full textThe purpose of this research is to examine the extent of instructional leadership of principals in high performing secondary schools in the metropolitan area of Cape Town, Western Cape. A mixed methods design of quantitative and qualitative research was undertaken. For the quantitative phase, the Principal Instructional Management Rating Scale (PIMRS) was administered to 5 principals and 136 teachers. One sample t-tests found statistically significant differences between the mean scores of principals and those of teachers. Data analysis of the PIMRS indicated that principals were most active in protecting instructional time, promoting professional development, providing incentives for learning and framing the school’s goals and least active in supervising and evaluating instruction, maintaining a high visibility and providing incentives for teachers. In the qualitative phase, interviews with the five principals yielded a result that underscores the value which principals place on professional accountability, trusting teachers to deliver the curriculum, building coherence, promoting professional development, giving professional autonomy and fostering relationships. The study found that the principal’s role is multi-faceted and complex and is neither limited to the instructional leadership behaviours of the PIMRS nor to the job description of the Personnel Administration Measures (PAM). Instructional leadership functions not measured by the PIMRS, such as the appointment of teachers, selection of pupils, engaging with stakeholder groups, establishing internal coherence and building trust by sharing instructional leadership practises with senior teachers were very important. School leaders internalize the expectations embedded in accountability systems and have woven these into an internal set of expectations and responsibilities that represent the school’s internal accountability systems. The thesis concludes with the view that both shared leadership and instructional leadership are important as they are indirectly related to pupil achievement.

Full textEm 1985, Mehra e Prescott levantaram uma questão que até hoje não foi respondida de forma satisfatória: o prêmio de risco das ações americanas é muito maior do que poderia ser explicado pelo “paradigma neoclássico de finanças econômicas” (financial economics) representado pelo modelo C-CAPM. E, a partir de então, este problema não resolvido ficou conhecido como o “Equity Premium Puzzle” (EPP) ou o “Enigma do Prêmio (de risco) das Ações”. Este enigma estimulou a produção de uma série de artigos, dissertações e teses que tentaram ajustar os modelos intertemporais de utilidade esperada aos dados dos mercados financeiros. Dentro deste contexto, esta tese busca (i) revisar a evolução histórica da teoria dos modelos de maximização da utilidade intertemporal dos agentes, (ii) analisar os pressupostos e conceitos chaves desses modelos, (iii) propor um novo modelo que seja capaz de solucionar o EPP, (iv) aplicar este modelo proposto aos dados históricos anuais entre 1929 e 2004 e (v) validar a lógica deste modelo através das metodologias Mehra-Prescott e Hansen-Jagannathan. Esta tese faz uma crítica de que os estudos até aqui desenvolvidos tentaram explicar a dinâmica de um mercado financeiro altamente sofisticado, através de um modelo de economia não-monetária e de subsistência. Assim, a sua contribuição consiste na alteração desse pressuposto de uma economia de subsistência, considerando que a renda disponível do setor privado não seja integralmente consumida, mas que também possa ser poupada. Assumindo que as pessoas obtêm satisfação (utilidade) tanto pelo consumo atual como pela poupança atual (que será o consumo futuro), será deduzido que a utilidade marginal de consumir é igual à de poupar, em todo e qualquer período. Com base nisso, a utilidade marginal a consumir é substituída pela utilidade marginal de poupar dentro do modelo básico do C-CAPM. Para reforçar a idéia de que o modelo desta tese usa dados de poupança em vez de consumo, ao longo do trabalho ele será chamado de Sanving-CAPM, ou S-CAPM. Este novo modelo mostrou-se capaz de solucionar o EPP quando submetidas às abordagens Mehra-Prescott e Hansen-Jagannathan.
In 1985 Mehra and Prescott raised a question that has not been answered satisfactorily: the equity premium of American shares is much higher than it could be explained by the "neoclassical paradigm of financial economics" represented by CCAPM models. And, since then, this non-solved issue is known as the Equity Premium Puzzle (EPP). This puzzle has stimulated the production of a series of articles, theses and dissertations that tried to adjust the intertemporal expected utility models to the financial markets' data. In this context, this doctoral dissertation aims to (a) revise the historical evolution of model theory of maximization of intertemporal expected utility, (b) analyze the key assumptions and concepts of these models, (c) propose a new model that can solve the EPP, (d) apply the proposed model to the historical data between 1929 and 2004, and (e) validate the logic of this model through the MehraPrescott and Hansen-Jagannathan methodologies. This doctoral dissertation criticizes that the studies so far formulated have tried to explain the dynamics of highly sophisticated financial markets through a model of non-monetary exchange economy. Hence, its contribution consists of the changing of this assumption of a exchange economy considering that the available income of the private sector is not fully consumed, but rather also saved. Taking into account that people can obtain satisfaction (utility) with the present consumption as well as with the present savings (that will be the future consumption), it will be deduced that the marginal utility of consuming is replaced by the marginal utility of saving within the basic C-CAPM model. To reinforce this idea that the model of this doctoral dissertation uses data of savings rather than consumption, throughout the study it will be called Saving-CAPM or S-CAPM. This new model has proved to be capable of solving the EPP when submitted to the Mehra-Prescott and HansenJagannathan approaches.

Full textFreshwater scarcity and river pollution has become a serious challenge for governments and scientists. Worldwide, governments have a responsibility to provide their populations with enough clean water for their domestic needs. Scientists will have an enormous task to find a way to purify polluted water, because of its vital role in human lives and an increasing demand for water consumption due to population growth. Although the water from the Bottelary River is used on a daily basis for farming activities, its pollution level as well as spatial distribution of effluents in the catchment is unknown. In the present study, I took monthly water samples from six sampling points for laboratory analysis. The laboratory determined concentration levels of phosphorous, chloride, nitrate, and nitrate nitrogen (N03N), as well as the chemical oxygen demand (COD) and suspended solids from the samples. On the same occasion's pH, dissolved oxygen, electrical conductivity and temperature were measured in-situ using a multi-parameter reader. The results were then compared with the South African Water Quality Guidelines for Aquatic Ecosystems and for irrigation (DWAF, 1996a, 1996c). The non-point pollution source (NPS) model was used to generate predictions of the pollution level from the land-uses and use the data obtained from the field to validate the model predictions. Finally, I performed a two-factorial A One-way Analysis of Variance (ANOVA) without replication to assess the spatial and temporal variation of the measured variables along the river. The findings of the study have shown that the concentration levels of some compounds are below the Target Water Quality Range (TWQR) set by the Department of Water Affairs and Forestry (DWAF, 1996a, 1996b, 1996c) while, the concentrations of chloride, total nitrogen and water quality variables such as electrical conductivity, suspended solids, are higher than the TWQR (DWAF, 1996a, 1996b, 1996c). Based on the above findings water of the Bottelary River can have negative effects on the environment and human lives because of the concentration level of these compounds. It was therefore recommended that, environmentally friendly measures and practices must be undertaken in order to decrease the pollution and avoid further pollution of the river.
