Grade 12 learners in one Namibian secondary school participated in a study of science process skills implied in their International General Certificate of Secondary Education (IGCSE) physical science syllabus. The study aimed at finding out learners’ ability to identify science process skills in their physical science syllabus, criteria used to identify skills and whether any relationship existed between learners’ achievement in performing skills and learners’ ability in identifying the skills. Four physical science syllabus topics were taught. Learners performed and identified science process skills in learning and assessment tasks. A One Group Pretest-Posttest research design was used in a combined qualitative and quantitative research method. Data revealed that learners identified science process skills. Science processes performed during learning experiences were used as criteria to confirm presence of the skills. Learners’ achievement increased in performing and identifying science process skills after intervention activities. There seemed no relationship between learners’ achievement in performing and learners’ ability in identifying science process skills. / Science and Technology Education / M. Ed.

[pt] A compreensão dos atuais processos produtivos é essencial neste momento em que o conhecimento tornou-se um importante gerador de valor. Uma visão holística dos conhecimentos que estão disseminados, de forma dispersa, entre profissionais, consultores e acadêmicos é necessária para a síntese de novas teorias da produção. Pesquisadores de gerência de operações freqüentemente usam mapeamento causal como um mecanismo para construir e comunicar teorias, particularmente em suporte à pesquisa empírica. As abordagens mais usuais para capturar dados cognitivos para um mapa causal são brainstorming e entrevistas, os quais exigem muito tempo e apresentam um significativo custo em sua implementação. Esta tese visa gerar uma metodologia (Metodologia Evocativa para Mapeamento Causal - ECMM) voltada para aplicação em pesquisa sobre gerência de operações para coletar e estruturar dados disseminados de forma desagregada, como conhecimento e experiência profissional e acadêmica, contidos nas opiniões de um grande número de especialistas dispersos demograficamente e geograficamente. Isto é alcançado evocando opiniões, codificando-as em variáveis e reduzindo o grupo em conceitos e relações. Tem-se uma especial preocupação em conseguir este objetivo em tempo factível e com baixo custo. A coleta de dados é assíncrona, via Internet, possui dois ou três turnos (à semelhança do método Delfos). A análise de dados usa codificação, técnica de grupamento hierárquica e escalamento multidimensional para identificar conceitos na forma de mapas cognitivos. A ECMM foi ilustrada com aplicações que demonstram sua viabilidade. Aplicou-se nas áreas de gestão da cadeia de suprimento (SCM) e administração de serviços (SM) com a participação de aproximadamente 1.300 respondentes de empresas e universidades de quase 100 países. Dentre os desdobramentos para pesquisas futuras propõe-se aplicar nas áreas de ECMM em SCM e SM visando a uni-las em um tema: gestão da cadeia de suprimento de serviços. / [en] The understanding of the present productive processes is essential at this moment when knowledge became an important value creator. A holistic vision of the pieces of knowledge that are spread out and dispersed among practitioners, consultants and academics is necessary for the synthesis of new theories of production. Operations management researchers often use causal mapping as a key tool for building and communicating theory, particularly in support of empirical research. The widely accepted approaches for capturing cognitive data for a causal map are informal brainstorming and interviews, which require a time- consuming and significant cost of implementation. This dissertation aims at creating a methodology (Evocative Causal Mapping Methodology - ECMM) intended for use in operations management research for collecting and structuring dispersed data spread out as practical and research knowledge, and experience contained in the opinions of a large number of specialists demographically and geographically scattered. This is accomplished by evoking opinions, encoding them into variables and reducing the resulting set to concepts and relationships. A special concern is to achieve this goal in a feasible time and cost- efficient way. ECMM consists of two or three round, Delphi- like, Internet-based asynchronous data collection, and a data analysis that uses a coding panel of experts, hierarchical cluster analysis and multidimensional scaling for identifying concepts on cognitive map formats. Applications illustrate ECMM and demonstrate its feasibility. They were developed on supply chain management (SCM) and service management (SM) involving about 1,300 respondents of companies and universities of about 100 countries. Among possible unfolding future studies, this dissertation proposes to apply ECMM in SCM and SM aiming at unifying them into a single topic: service supply chain management.

The dissertation deals with semantic relations between adjectives and deadjectival verbs in Czech. It focuses on the question how the property scale conveyed by adjectives is encoded in the semantics of deadjectival verbs. After the first chapter which presents the topic of the dissertation, in the second chapter, I describe the theoretical and methodological context of contemporary linguistics from a broader perspective in order to relate the theoretical and methodological procedures present in this paper to the current linguistic development. The third chapter pursues the semantics of adjectives in Czech and various approaches to their classification. It presents a scalar classification of adjectives according to which adjectives denote a scale of some property, i.e. an ordered set of degrees along a dimension. With support of empirical research (based on a questionnaire survey and corpus data) I show that it is possible to implement the scalar model into the description of Czech adjectives. This approach states that adjectives are one of many means in language that serve to express measurement (and attribute it to objects and individuals). At the end of the chapter, I propose a classification of Czech adjectives and generalize prototypical semantics of adjectival classes by vector constructions...

This project had two primary goals: (1) to explore opportunities to further a deep-ocean vehicle’s reach using alternative pressure spheres, and (2) to implement an existing deep-ocean vehicle (lander) in active scientific research. I gained a greater understanding of the limitations and design choices made for existing pressure spheres using Finite Element Analysis (FEA). My simplified FEA model predicted sphere failure for the existing 30% Fiber Glass 70% Nylon injection molded spheres at an external pressure of 3,954psi or 2,690m ocean-depth (only a 7.38% error compared to the tested minimum failure depth), so I determined it a valid model. I also explored alternative designs and materials that could be used for pressure spheres in deep-sea applications. Existing pressure sphere models filled with an incompressible fluid failed at 12,670psi or 8,621m ocean-depth - over three times the depth of the same sphere filled with air. Next, I varied the sphere thickness of existing spheres to determine its impact on depth rating. While the increased thickness did provide an increase in depth rating, there were diminishing returns as the sphere was made thicker. I deemed both of these design options infeasible for our application. To consider the use of laminated composite spheres, the addition of an equatorial ring was required to manufacture O-ring seals safely and reliably. A simple cylindrical equatorial ring model using a stainless-steel ring had a predicted failure at 3,017psi or 2,053m ocean-depth. While this model predicted failure at 637m shallower than the sphere without the ring, it was the only ring material tested to reach the rated depth for the existing pressure spheres (2km), so I concluded stainless-steel is the best ring material. A spherical stainless-steel equatorial ring design was then analyzed which predicted failure at 3,915psi or 2,664m ocean-depth – only 8.3% less than the original sphere with no ring. Because of its successful performance and near identical results to the original model, I determined a stainless-steel spherical equatorial ring is the best option for laminated composite sphere sealing. Finally, I analyzed three different kinds of laminated composite pressure spheres: two carbon fiber and one fiber glass. Each laminate was designed to be quasi-isotropic and as close to 0.8” thick as possible to keep it consistent with the original sphere design. The sphere made of 584 Carbon Fiber with a lay-up of: [[-45/45/0/90]6]s was found to predict failure at 10,000psi or 6,804m ocean-depth, more than 2.5 times that of the original sphere. Next, a model made of 282 Carbon Fiber with a lay-up of: [[-45/45/0/90]11]s predicted failure at 9,242psi or 6,289m ocean-depth – more than 2.3 times as deep as the original pressure spheres. Lastly, a sphere of 7781 Fiber Glass with a lay-up of: [[-45/45/0/90]11]s predicted failure at 6,630psi or 4,511m ocean-depth – about two-thirds the depth of the 584 Carbon Fiber composite, but more than 1.6 times the depth of the original sphere. While real-life applications of these materials would include design modifications and manufacturing imperfections which would lower their maximum depth rating, these results are highly encouraging and show that all three materials could be viable options for future production. Additionally, through partnership with Dr. Crow White and his marine science undergraduate students, I completed numerous deployments for a Before and After Controlled Impact (BACI) study on the area of the proposed windfarm off the coast of Morro Bay, CA. Many modifications were made to the existing lander which enabled it to successfully be implemented in these studies including a new bait containment unit, light color filters, a GPS tracking device, and a large vessel recovery device. A total of 5 pier deployments and 3 boat deployments were conducted by my team over the course of 6-months. Planning for these deployments included accounting for budgeting, weather, permitting, and multi-organizational logistics while working with both NOAA and the Cal Poly marine operations staff.

Instrumental disparities and soil moisture are two of the key limitations in implementing spectroscopic techniques in the field. This study sought to address these challenges through two objectives. The first objective was to assess Visible-near infrared (VisNIR) and mid-infrared (MIR) spectroscopic approaches and explore the feasibility of transferring calibration models between laboratory and portable spectrometers. The second objective addressed the challenge of soil moisture and its impact on spectra. The portable spectrometers demonstrated comparable performance to their laboratory-based counterparts in both regions. Spiking with extra-weight, was the most effective calibration transfer method eliminating disparities between instruments. The samples were rewetted under nine controlled conditions for the moisture study. Results showed that spiking with extra weights significantly outperformed other techniques and model enhancement was insensitive to the moisture contents. Findings of this study will be helpful for development and deployment of in situ sensors to enable field implementation of spectroscopy.

This project seeks to determine, to what extent the culture of early Israel (1250-1000 BC) is similar to African cultures, more specifically, to that of the Lemba. However, a comparison between the cultures of early Israel and those of certain African tribes is not the primary objective in this case. This project is neither an anthropological study nor does it intend to mainly focus on the Lemba as such -though this may appear to be the case. This endeavour primarily fits into the ambit of Old Testament Studies. The investigation into the Lemba is meant to be subsidiary to the point of contingence between their culture and Old Testament customs and traditions, and how this information affects the interpretation of the Old Testament and its teaching in Africa. A number of comparisons between the early Israelite religion as reflected in the Old Testament and the Lemba are drawn. Though the qualitative research (inductive approach) is employed in the field work, the greatest part of the data on religious perspectives and practices is mediated by the theory of a phenomenological approach as advocated by Ninian Smart on matters of experience, mythology, ritual, and ethical/judicial dimensions. Therefore, the approach is also deductive. The Lemba is a very specific group with claims about Israelite/Judaic origins. Their early departure from Israel (according to them ca 586 BC) can mean that there are remnants of a very ancient type oflsraelite religion, now valuable when juxtaposed to that of early Israel. This study takes Lemba traditions seriously, but finally does not verify or falsify Lemba claims - but the outcomes in this thesis may take this debate a step further. Their claims make them special and extremely interesting to study from the point of view of oral cultures. Their oral culture is constitutive of their world-view and self-understanding or identity. It incorporates the role of oral traditions, history and historiography and parallels are drawn between orality in early Israelite and Lemba religions. The reciprocity between orality and inscripturation of traditions, yielding valuable information on what may have happened in the developent of traditions in Israel, are also attended to in this project. Nevertheless, this project is primarily a search for the understanding and relevance of the Old Testament in Afiica and is, therefore, a selective and not an exhaustive comparison between the Lemba and early Israel. And so, taking cognisance of the hermeneutic of contextualisation in Africa in particular, a teaching module syllabus for Old Testament Studies is developed, of which the very strands of religion among the Lemba and early Israel are constitutive for teaching Old Testament Studies in present-day African cultures (and perhaps elsewhere). / Biblical and Ancient Studies / D.

Text in English / Intimate Partner Violence (IPV) is a major problem among women of child-bearing age in Uganda. This study explored the IPV experiences of women living in urban slums and their health needs in order to assist in developing strategies to prevent and respond to IPV. This was a cross-sectional explanatory study using a mixed methods approach among women aged 20-45 years in Kabalagala slums, Kampala, Uganda. The quantitative survey data was collected using a structured questionnaire while qualitative data was collected using in-depth interviews. Quantitative data were collected from a random sample of 372 women and qualitative data from a purposive sample of 48 women with IPV experiences. The quantitative data was analysed using STATA (version 11), and the qualitative data was coded and analysed manually into thematic content. The study revealed a high overall lifetime prevalence of IPV. The different IPV forms prevalent in the study population included psychological (99.7%), economic (93%), physical (92%) and sexual (88%). Physical violence in the last one year was 91%. The qualitative findings revealed the manifestations of IPV in this context. Furthermore, the physical and psychological health impacts of IPV included but were not limited to injuries; chronic pain and complications; HIV infection; low self-esteem; stress and fear of death, and loss of relationships. The researcher proposed three strategies to prevent and respond to IPV, namely implementing economic empowerment and poverty reduction programmes for women; strengthening the legal and justice system to respond appropriately to the problem of IPV, and improving the social and institutional support including training of health workers to prevent and respond to IPV. The proposed regulation of substance and alcohol use would also contribute to reducing IPV prevalence and scaling-up the response. / Health Studies / D. Litt. et Phil. (Health Studies)

This study explores how heavily tattooed women with a history of childhood sexual abuse give meaning to their tattooing practices in view of the recent appropriation of tattooing by the mainstream. Embodied feminist poststructuralist theory revealed the ways that dominant discourses on gender, beauty, painful body modifications, and childhood sexual abuse intersect and interact in attempts to shape the identities of the participants. These intersections also reveal the participants’ resistance strategies and the process of identity transformation they engage in as they get tattoos. The constitution of identities through discourses offers alternative ways of seeing this population, challenging dominant discourses regarding female survivors of childhood sexual abuse tattooing practices. The research methodology used was a qualitative approach based on ‘interpretive interactionism.’ This approach makes visible and accessible to the reader, the problematic lived experiences of the participants through their narratives. The research methods involved several in-depth interviews with three heavily tattooed women who were survivors of childhood sexual abuse. The analysis involved interpreting the meanings participants gave to their tattooing practices in relation to how they construct their identities as they negotiate gender ideology, the tattoo renaissance, self-injury practices as related to tattooing, healing from childhood sexual abuse and oppressive beauty ideals. This study unearthed alternative ways of conceptualizing painful practices, female aesthetics, tattooing, women’s body reclamation projects, emotional trauma release, embodied domination, and bodily learning. It also offered insights into how the participants fragment their subjectivities and actively take over the authorship of their identities as they also try to positively influence their environments, challenge beauty norms and seek healing outside of traditional therapeutic environments.
