Since passing its Death with Dignity Act into law in 1997, Oregon remains the only state in America to make physician-assisted suicide an explicit legal right. Currently, the legality of physician-assisted suicide falls under the jurisdiction of each individual state. Had the United States Supreme Court ruled differently in a recent case, however, the issue would have transferred to federal jurisdiction. The Death with Dignity National Center (DDNC) takes responsibility for developing the original Death with Dignity Act and has since moved on to proposing similar legislation in other states. It also champions states' rights, fearing that placing physician-assisted suicide under federal jurisdiction would severely hinder its goals. The DDNC has led the legal movement for making physician-assisted suicide an end of life choice available in each state, as well as for keeping that decision at the state level. Utilizing a content analysis, this study coded for frames used by the DDNC in its press releases and frames used in newspaper coverage of death with dignity across the same period of time. It was found that press releases about and newspaper coverage of the death with dignity social movement shared significant correlations in terms of the frames each used, as well as the level of substance given to these frames. Few significant correlations were found, however, for frame valence. It seems as though discussion of this social movement utilizes the same substantive or ambiguous frames, but cannot decide whether these frames are positive, neutral, or negative. / Master of Arts

Developing a rational method of design has long been the goal of structural engineering. For steel structures, through the development of plastic design and electronic computation, this now seems possible. Several methods have been proposed within the last five years, and one method has been programmed for the digital computer. Five methods are here discussed and compared and the method of Heyman and Prager is investigated in detail. The assumptions and restrictions of the Heyman-Prager method, along with the computer program developed by Kalker, are investigated and discussed. The author attempts to evaluate the usefulness of, and place the Heyman-Prager method in a proper perspective in the overall planning, design, analysis phases of the total structural evolution. It is concluded that a more efficient computer program could be developed to facilitate the structural solution and some methods by which this might be accomplished are suggested. A comprehensive bibliography is provided which traces the development of practical minimum weight, plastic design from its inception up to the present time. / Master of Science

This study focuses on the representation of masculine imagos in the South African novelist Eben Venter’s novel oeuvre and more specifically on the multifaceted nature of Venter’s delineation of masculinity. His novels Foxtrot van die Vleiseters (1993), Ek stamel ek sterwe (1996) (translated into English as My beautiful death ((2004)) and Santa Gamka (2009) were selected to represent Venter’s novel oeuvre. The male protagonist in each novel may be viewed as typical representations of masculine imagos in his novels. The workability of cognitive narratology as a literary approach to analyse and interpret novels is tested by identifying the frames and scripts within the selected novels. Cognitive frames in narratives are those backdrops against which the events take place, while the actions executed by the characters are read as cognitive scripts. These scripts create the projected masculinity imagos of the male protagonists. When reading the novels, the reader is confronted with various cognitive choices of which three are especially important. The first is the choice to discard existing ideas and perceptions in order to make room for new ideas and perceptions. The second choice is to modify existing ideas and adjust them by means of the cognitive processing of information in the novels. The last choice entails the total rejection of the new ideas. Irrespective of the cognitive processes that occur during the reading process, the representation of masculinity in the novels will inevitably have an effect on the way in which the reader will experience masculinity in future. In the characters of Petrus Steenekamp (Foxtrot van die Vleiseters), Konstant Wasserman (Ek stamel ek sterwe) and Lucky Marais (Santa Gamka) Venter illustrates the complexity of the masculinity issue due to the cultural, social and political frames with which people are encoded. This encoding is also reflected in the scripts that are determined by the characters’ behaviour and actions. Venter demonstrates sensitivity and compassion for all the characters in his novels and his representation of masculinity instils sensitivity and compassion in readers. This instilment will most probably create a better understanding of masculinity, as well as humanity, within the cognition of the reader. The most important finding is that it is indeed possible to use cognitive narratology as literary approach to analyse and interpret the chosen novels in order to make valid conclusions – in this case with regard to the complex delineation of multifaceted masculine imagos within Eben Venter’s novel oeuvre. Further deductions include those made about the appearance of different images of masculinity within Venter’s novel oeuvre and especially how the farm frame and the father/son relationship frame manifest prominently in Venter’s novels. / MA (Afrikaans and Dutch), North-West University, Potchefstroom Campus, 2014

The purpose of this essay is to highlight the space students receive through teachers´ questions in text conversations from a power perspective. The empirical data is based on observations in the classrooms, and student and teacher interviews. The ambition of this essay is to investigate the way power and standards reproduce and are created in classrooms. This is preformed through observations. Through interviews with students and teachers the study aims to display their experiences and reflections about the space provided. Methods used in the study are both quantitative and qualitative. The material in this study is represented by two schools and four classrooms in grade two. The theoretical framework is based on Foucault's theory of power and on Åsa Bartholdsson´s concept of "friendly exercise of power". The theoretical framework is also based on exercise of power as it has been analyzed in Donald Broady´s "educational frameworks" and the relationship between these frames and power, as well as the analytical concepts of speaking space, action space and interaction space. The results show that speaking space in the classroom is dominated by closed questions. To answer the teacher's questions the student needs to sit still on a chair and raise the hand and also that teachers do not create enough opportunities for students to refer to each other’s reply in conversations about a text. The conclusion that can be drawn is that teachers teach students through hidden power shapes and democratic forms for students' future roles as democratic citizens.

Thesis (MScEng)-- Stellenbosch University, 2013. / ENGLISH ABSTRACT: Most of the parameters involved in the design and analysis of structures are of stochastic nature. This is, therefore, of paramount importance to be able to perform a fully stochastic analysis of structures both in component and system level to take into account the uncertainties involved in structural analysis and design. To the contrary, in practice, the (computerised) analysis of structures is based on a deterministic analysis which fails to address the randomness of design and analysis parameters. This means that an investigation on the algorithmic methodologies for a component and system reliability analysis can help pave the way towards the implementation of fully stochastic analysis of structures in a computer environment. This study is focused on algorithm development for component and system reliability analysis based on the various proposed methodologies. Truss structures were selected for this purpose due to their simplicity as well as their wide use in the industry. Nevertheless, the algorithms developed in this study can be used for other types of structures such as moment-resisting frames with some simple modi cations. For a component level reliability analysis of structures different methods such as First Order Reliability Methods (FORM) and simulation methods are proposed. However, implementation of these methods for the statistically indeterminate structures is complex due to the implicit relation between the response of the structural system and the load effect. As a result, the algorithm developed for the purpose of component reliability analysis should be based on the concepts of Stochastic Finite Element Methods (SFEM) where a proper link between the finite element analysis of the structure and the reliability analysis methodology is ensured. In this study various algorithms are developed based on the FORM method, Monte Carlo simulation, and the Response Surface Method (RSM). Using the FORM method, two methodologies are considered: one is based on the development of a finite element code where required alterations are made to the FEM code and the other is based on the usage of a commercial FEM package. Different simulation methods are also implemented: Direct Monte Carlo Simulation (DMCS), Latin Hypercube Sampling Monte Carlo (LHCSMC), and Updated Latin Hypercube Sampling Monte Carlo (ULHCSMC). Moreover, RSM is used together with simulation methods. Throughout the thesis, the effciency of these methods was investigated. A Fully Stochastic Finite Element Method (FSFEM) with alterations to the finite element code seems the fastest approach since the linking between the FEM package and reliability analysis is avoided. Simulation methods can also be effectively used for the reliability evaluation where ULHCSMC seemed to be the most efficient method followed by LHCSMC and DMCS. The response surface method is the least straight forward method for an algorithmic component reliability analysis; however, it is useful for the system reliability evaluation. For a system level reliability analysis two methods were considered: the ß-unzipping method and the branch and bound method. The ß-unzipping method is based on a level-wise system reliability evaluation where the structure is modelled at different damaged levels according to its degree of redundancy. In each level, the so-called unzipping intervals are defined for the identification of the critical elements. The branch and bound method is based on the identification of different failure paths of the structure by the expansion of the structural failure tree. The evaluation of the damaged states for both of the methods is the same. Furthermore, both of the methods lead to the development of a parallel-series model for the structural system. The only difference between the two methods is in the search approach used for the failure sequence identification. It was shown that the ß-unzipping method provides a better algorithmic approach for evaluating the system reliability compared to the branch and bound method. Nevertheless, the branch and bound method is a more robust method in the identification of structural failure sequences. One possible way to increase the efficiency of the ß-unzipping method is to define bigger unzipping intervals in each level which can be possible through a computerised analysis. For such an analysis four major modules are required: a general intact structure module, a damaged structure module, a reliability analysis module, and a system reliability module. In this thesis different computer programs were developed for both system and component reliability analysis based on the developed algorithms. The computer programs are presented in the appendices of the thesis. / AFRIKAANSE OPSOMMING: Meeste van die veranderlikes betrokke by die ontwerp en analise van strukture is stogasties in hul aard. Om die onsekerhede betrokke in ontwerp en analise in ag te neem is dit dus van groot belang om 'n ten volle stogastiese analise te kan uitvoer op beide komponent asook stelsel vlak. In teenstelling hiermee is die gerekenariseerde analise van strukture in praktyk gebaseer op deterministiese analise wat nie suksesvol is om die stogastiese aard van ontwerp veranderlikes in ag te neem nie. Dit beteken dat die ondersoek na die algoritmiese metodiek vir komponent en stelsel betroubaarheid analise kan help om die weg te baan na die implementering van ten volle rekenaarmatige stogastiese analise van strukture. Di e studie se fokus is op die ontwikkeling van algoritmes vir komponent en stelsel betroubaarheid analise soos gegrond op verskeie voorgestelde metodes. Vakwerk strukture is gekies vir die doeleinde as gevolg van hulle eenvoud asook hulle wydverspreide gebruik in industrie. Die algoritmes wat in die studie ontwikkel is kan nietemin ook vir ander tipes strukture soos moment-vaste raamwerke gebruik word, gegewe eenvoudige aanpassings. Vir 'n komponent vlak betroubaarheid analise van strukture word verskeie metodes soos die "First Order Reliability Methods" (FORM) en simulasie metodes voorgestel. Die implementering van die metodes vir staties onbepaalbare strukture is ingewikkeld as gevolg van die implisiete verband tussen die gedrag van die struktuur stelsel en die las effek. As 'n gevolg, moet die algoritme wat ontwikkel word vir die doel van komponent betroubaarheid analise gebaseer word op die konsepte van stogastiese eindige element metodes ("SFEM") waar 'n duidelike verband tussen die eindige element analise van die struktuur en die betroubaarheid analise verseker is. In hierdie studie word verskeie algoritmes ontwikkel wat gebaseer is op die FORM metode, Monte Carlo simulasie, en die sogenaamde "Response Surface Method" (RSM). Vir die gebruik van die FORM metode word twee verdere metodologieë ondersoek: een gebaseer op die ontwikkeling van 'n eindige element kode waar nodige verandering aan die eindige element kode self gemaak word en die ander waar 'n kommersiële eindige element pakket gebruik word. Verskillende simulasie metodes word ook geïmplimenteer naamlik Direkte Monte Carlo Simulasie (DMCS), "Latin Hypercube Sampling Monte Carlo" (LHCSMC) en sogenaamde "Updated Latin Hypercube Sampling Monte Carlo" (ULHCSMC). Verder, word RSM tesame met die simulasie metodes gebruik. In die tesis word die doeltreffendheid van die bostaande metodes deurgaans ondersoek. 'n Ten volle stogastiese eindige element metode ("FSFEM") met verandering aan die eindige element kode blyk die vinnigste benadering te wees omdat die koppeling tussen die eindige element metode pakket en die betroubaarheid analise verhoed word. Simulasie metodes kan ook effektief aangewend word vir die betroubaarheid evaluasie waar ULHCSMC as die mees doeltre end voorgekom het, gevolg deur LHCSMC en DMCS. The RSM metode is die mees komplekse metode vir algoritmiese komponent betroubaarheid analise. Die metode is egter nuttig vir sisteem betroubaarheid analise. Vir sisteem-vlak betroubaarheid analise is twee metodes oorweeg naamlik die "ß-unzipping" metode and die "branch-and-bound" metode. Die "ß-unzipping" metode is gebaseer op 'n sisteem-vlak betroubaarheid ontleding waar die struktuur op verskillende skade vlakke gemodelleer word soos toepaslik vir die hoeveelheid addisionele las paaie. In elke vlak word die sogenaamde "unzipping" intervalle gedefinieer vir die identifikasie van die kritiese elemente. Die "branch-and-bound" metode is gebaseer op die identifikasie van verskillende faling roetes van die struktuur deur uitbreiding van die falingsboom. The ondersoek van die skade toestande vir beide metodes is dieselfde. Verder kan beide metodes lei tot die ontwikkeling van 'n parallelserie model van die strukturele stelsel. Die enigste verskil tussen die twee metodes is in die soek-benadering vir die uitkenning van falingsmodus volgorde. Dit word getoon dat die "ß-unzipping" metode 'n beter algoritmiese benadering is vir die ontleding van sisteem betroubaarheid vergeleke met die "branch-and-bound" metode. Die "branch-and- bound" metode word nietemin as 'n meer robuuste metode vir die uitkenning van die falings volgorde beskou. Een moontlike manier om die doeltre endheid van die "ß-unzipping" metode te verhoog is om groter "unzipping" intervalle te gebruik, wat moontlik is vir rekenaarmatige analise. Vir so 'n analise word vier hoof modules benodig naamlik 'n algemene heel-struktuur module, 'n beskadigde-struktuur module, 'n betroubaarheid analise module en 'n sisteem betroubaarheid analise module. In die tesis word verskillende rekenaar programme ontwikkel vir beide sisteem en komponent betroubaarheid analise. Die rekenaar programme word in die aanhangsels van die tesis aangebied.

Thesis (MEng)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Construction of structural concrete frames may take place by using either cast in-situ or precast methods. With the cast in-situ method, these elements are constructed on the construction site as needed. Precast construction on the other hand is more resembles a line. The elements are constructed in a precast yard in a systematic fashion and once completed, they are taken to the construction site where they are to be erected. This study identifies the aspects and attributes which influence the quality of concrete during the construction phase of these two construction methods. The study is independent from the conceptual or design phase. Information regarding these aspects and attributes were obtained from literature and from contractors in industry through interviews and site visits. The literature review also focuses on quality management techniques and factors that influence quality in the construction environment. The information obtained from the site visits and literature was used to design a survey which was sent out to a number of respondents. A comparison between in-situ and precast construction was made based on the results of the survey. The synthesis of the research findings can be used by project teams to help them decide on the choice between in-situ and precast construction. It was found that precast construction is better for durability, and fitness for purpose is less complex for the in-situ solution. Recommendations for future studies are provided at the end of the document. / AFRIKAANSE OPSOMMING: Konstruksie van beton struktuurrame kan plaasvind deur die gebruik van in-situ of voorafvervaardigde metodes. Met die in-situ metode, word hierdie elemente op die terrein gebou soos benodig. Tydens voorafvervaardigde konstruksie aan die ander kant is die konstruksie soortgelyk aan 'n produksielyn. Die elemente word gegiet in 'n voorafvervaardingsterrein in 'n sistematiese wyse, en sodra dit voltooi is, word dit na die konstruksie terrein geneem waar dit opgerig word. Hierdie studie identifiseer die aspekte en eienskappe wat 'n invloed op die kwaliteit van beton het tydens die konstruksiefase van hierdie twee konstruksie metodes. Die studie is onafhanklike van die konseptuele of ontwerp fases. Inligting rakende hierdie aspekte en eienskappe is verkry uit die literatuur en van kontrakteurs in die bedryf deur middel van onderhoude en besoeke. Die literatuur fokus ook op die gehalte, bestuurs-tegnieke en faktore van gehalte in die bou-omgewing. Die inligting is verkry deur ‘n vraelys wat aan 'n aantal respondente gestuur is. 'n Vergelyking tussen in-situ en voorafvervaardigde konstruksie is vervolgens gemaak op grond van die resultate van die opname. Die sintese van die bevindinge kan gebruik word deur projek spanne om hulle te help besluit oor die keuse tussen in-situ en voorafvervaardigde konstruksie. Die resultate dui daarop dat voorafvervaardigde konstruksie beter is vir duursaamheid, maar passing op terrein is minder kompleks vir die in-situ oplossing. Aanbevelings vir toekomstige ondersoeke word aan die einde van die studie gemaak.

The Basque conflict has waged since the 1950s in its current form. However, with the arrival of democracy 36 years ago, the Basque Country has been the scene of an intense peace mobilization, dominated by two peace organizations: Gesto por la Paz, a group of community organizations that mobilize to publicly reject political violence, and Lokarri/Elkarri, an organization that includes a conflict resolution proposal based on dialogue between conflicting parties. While there is some literature on these organizations, none has analysed their extraordinary impact on Basque society. This research explores how the Basque peace movement has impacted on the social and political culture of the Basque conflict. It seeks to understand the nature of this impact and to determine the channels and methods by which it was achieved, using frame analysis. Three interlinked questions serve to guide the research, asking first if there is a Basque Peace Frame and if it could be considered a master frame, how this Basque Peace Frame has evolved, and, finally, how the Basque Peace Frame has impacted on other Basque Civil Society Organizations related to the conflict. This qualitative research spans the period between the March 2006 declaration of ceasefire by ETA and the end of fieldwork for this research in September 2008. The research includes 18 in depth interviews, written media, and analysis of seven notable Basque social organizations related to the conflict, in addition to the two peace organizations mentioned above. The research found the impact of the Basque peace movement in the Basque Country is significant and rich. The Basque Peace Frame developed based on the rejection of the use of violence as a political tool and identifies that violence as the main barrier to achieving an inclusive conflict resolution. The Basque peace movement organizations developed a specific kind of mobilization to enforce the Basque Peace Frame based on silent and symbolic acts. The objective was to counter the former dynamics of mobilization that were contentious and directed to promote Basque national rights. The Basque Peace Frame proposed a change in the way the political collective identity was constructed in the Basque Country, showing that an association between nationalism and violence is not obligatory. The Basque Peace Frame has evolved and spread between social organizations in the Basque Country, using sympathetic identity networks as the main channel of frame diffusion. Even organizations that did not reject the use of contentious methods of protest are now questioning the use of violence, signifying exciting prospects for the future of non-violent political action in the Basque Country.

In order to probe how social movement messages foster participant mobilization, this study utilized an experimental design to investigate collective action frames, core messaging tasks that define problems, assign blame, convey a plan of action, and inspire participation. The study compared the effects of climate change messages that contain motivational frames with those that do not, incorporating the influence of resonance, and exposure to competing and counter frames. Results revealed that motivational frames contributed to mobilization, especially intention to act, under conditions of resonance and with exposure to counter frames. Salience primed participants to respond to motivational frames, however for some, motivational frames decreased intention to act. As social movements and climate change continue to profoundly shape our world in myriad ways, we will be better prepared to address those changes with information provided here.
