Summaries in Engish and Afrikaans / The goal of this research is to evaluate whether a personal and social skills program can effectively be implemented by social workers in a prison. A control- and experimental group were used in a quasiexperimental design. The respondents were twenty-four white, male, sentenced prisoners in Pretoria Central Prison. The Heimler scale for social functioning and the Hudson-scale for family relations are the standard questionnaires, which were utilised to measure results during the pre-testing and post-testing phase. All twenty-four respondents completed the scales during the pre- and post-testing phase. The Wilcoxon t-test and Mann-Whitney U-test were used for statistical purposes. A computer was used to process data. Both measurement scales confirmed positive results. The independent variable, that is, the personal and social skills program had an effect in the desired direction on respondents in the experimental group. The Hudson-scale for interpersonal relationships, however, showed more dramatic results. The results for the control group, showed noticeable decline in both social functioning of the respondents as well as experience of family relationships. / Die doel van hierdie navorsing is om te bepaal of maatskaplike werkers in 'n gevangenis 'n persoonlike en sosiale vaardigheidsprogram effektief kan implementeer.

Prevailing research presents evidence that links language proficiency to fundamental literacy acquisition. However, when language and literacy acquisition are simultaneous, as is the case with young (4-6 years) English language learners (ELL’s), who acquire literacy in a language not spoken at home in B.C. Canada, the research is limited. The aim of the study was to explore and compare the language and literacy profiles (LLP) of ELL’s and monolingual learners. The normative processes as elucidated in the theoretical frameworks of Bronfenbrenner’s ecosystemic model, Vygotsky’s sociocultural model and the Critical Theory (CT) model informed the comparative framework. In addition, the second language acquisition (SLA) theoretical frameworks purported by Chomsky, Vygotsky and Krashen are elaborated upon. A causal comparative approach to the mixed model research design and a complementary mixed methods approach is applied to the study. The study interactively investigated the cultural and linguistic diversity (CALD) of ELL’s and sought statistically significant differences between the language and literature profiles (LLP) of 25 ELL’s and his/her parent - whose home language is other than English during first time literacy acquisition - and 25 monolingual learners and his/her parent (selected via a simple, purposive, random sample strategy) when English is the language medium used in the inclusive classroom. The qualitative findings delineated the LLP of the ELL’s with regard to CALD, biographic and background details; the quantitative findings, delineated the at risk educationally vulnerable minority by virtue of their limited English proficiency (LEP) and limited emergent literacy and language profile (LLP). The identification of the at risk educationally vulnerable minority, informed the proposed theoretical framework for the study, namely, namely, LLP - Semiotic Scaffolding-From Theory to Practice and the attendant curriculum. Findings are discussed comparatively with the classic and current theoretical frameworks pertaining to child development, language acquisition for both first and second language acquisition (SLA) in addition to globalisation, inclusive education and social justice. The implication of the findings for policy makers, curriculum planners, schools, teachers, classrooms, parents and the learners are discussed. Opportunities for further research are noted. / Psychology of Education / D. Ed. (Psychology of Education)

Indiana University-Purdue University Indianapolis (IUPUI) / Although interprofessional education (IPE) opportunities can help prepare students for future practice and patient-centered care, many health professions students in the country are not educated in an environment with opportunities to learn with, from, or about students from other health professions. With upcoming curricular changes at the Indiana University School of Medicine (IUSM) and the Indiana University School of Nursing (IUSN), IPE remains at the forefront of these changes in both schools. To date, few studies have explored student, faculty, and administrators’ conceptualizations of IPE prior to formal implementation. Additionally, previous studies have not compared IPE conceptualizations across these groups. This multiple-case study explores and compares how groups of stakeholders from the IUSM (Indianapolis) and the IUSN (Indianapolis) conceptualize IPE. Data collection included the examination of discipline-specific public documents and one-on-one interviews (N=25) with pre-licensure students, clinical faculty, and administrators from each school. Coding and extraction of themes transpired through within-case and cross-case analysis and data supported the following findings: the ‘business of medicine’ may prevent IPE from becoming a priority in education; stakeholders’ conceptualizations of IPE are shaped through powerful experiences in education and practice; students desire more IPE opportunities at the institution; stakeholders at the IUSN have a long-standing investment in IPE; and the institution requires a ‘culture shift’ in order to sustain IPE efforts. The findings suggest that IPE belongs in all education sectors and IPE efforts deserve reward and reimbursement. The findings also insinuate that leadership, roles, and team training education belong in IPE and IPE culture requires all individuals’ (e.g., student, faculty, administrators, patients) commitment. Importantly, the institution must continue IPE development, research, and dissemination. These findings can help shape curricula as time progresses, increase the likelihood of developing a successful new curriculum, and prompt ongoing reflection about IPE. This information can influence how institutions approach IPE and may lead to a more successful and informed IPE curriculum in the first years of implementation. And, hopefully what is learned through IPE will be translated into healthcare practice environments.

Indiana University-Purdue University Indianapolis (IUPUI) / The substantial increase demand for electrical energy requires high efficient apparatus dealing with energy conversion. Several technologies have been suggested to implement power supplies with higher efficiency, such as multilevel and interleaved converters. This thesis proposes an energy conversion unit with an optimized number of output voltage levels per number of switches nL=nS. The proposed five-level four-switch per phase converter has nL=nS=5/4 which is by far the best relationship among the converters presented in technical literature. A comprehensive literature review on existing five-level converter topologies is done to compare the proposed topology with conventional multilevel converters. The most important characteristics of the proposed configuration are: (i) reduced number of semiconductor devices, while keeping a high number of levels at the output converter side, (ii) only one DC source without any need to balance capacitor voltages, (iii) high efficiency, (iv) there is no dead-time requirement for the converters operation, (v) leg isolation procedure with lower stress for the DC-link capacitor. Single-phase and three-phase version of the proposed converter is presented in this thesis. Details regarding the operation of the configuration and modulation strategy are presented, as well as the comparison between the proposed converter and the conventional ones. Simulated results are presented to validate the theoretical expectations. In addition a fault tolerant converter based on proposed topology for micro-grid systems is presented. A hybrid pulse-width-modulation for the pre-fault operation and transition from the pre-fault to post-fault operation will be discussed. Selected steady-state and transient results are demonstrated to validate the theoretical modeling.

Indiana University-Purdue University Indianapolis (IUPUI) / This research proposes state-of-the-art multilevel converter topologies and their modulation strategies, the implementation of a conventional flying-capacitor converter topology up to four-level, and a new four-level flying-capacitor H-Bridge converter confi guration. The three phase version of this proposed four-level flying-capacitor H-Bridge converter is given as well in this study. The highlighted advantages of the proposed converter are as following: (1) the same blocking voltage for all switches employed in the con figuration, (2) no capacitor midpoint connection is needed, (3) reduced number of passive elements as compared to the conventional solution, (4) reduced total dc source value by comparison with the conventional topology. The proposed four-level capacitor-clamped H-Bridge converter can be utilized as a multilevel inverter application in an electri fied railway system, or in hybrid electric vehicles. In addition to the implementation of the proposed topology in this research, its experimental setup has been designed to validate the simulation results of the given converter topologies.

Unemployment among young, less-educated coloured individuals is a major problem in the community of Worcester in the Western Cape. The purpose of the research study is to gain in-depth insight into the impact of unemployment on psychological well-being among young coloured people in Worcester. The study is based on a qualitative approach by conducting semi-structured interviews with twelve unemployed, coloured persons in Worcester. The ages of the participants ranged from 18 to 30 years, with the median age of 20.33 years. Purposive sampling and snowball techniques were used to select these unemployed young persons. Two instruments, a demographic questionnaire and a semi-structured interview guide, were used to gather data on the research participants. The transcribed data were analysed by means of content thematic analysis and aided by thematic network analyses. The findings of the study suggest that unemployed participants experience negative feelings daily as a result of their unemployment. Some participants blamed themselves for previous mistakes that they had made, they feel a sense of failure to provide for their children's needs as parents, they expressed feelings of guilt or shame, and compared themselves with employed peers, which is indicative of low self-esteem. Furthermore, unemployment has a financial impact on participants which includes financial dependency on others, unemployment serving as a barrier to being able to fulfil future plans and aspirations as well as unemployment having an effect on the social life of participants in that participants appear to withdraw from social interaction and isolate themselves. For some participants there was a loss of a sense of purpose experiencing difficulties in structuring their time and generally spent their time with passive and purposeless activities. Despite being unemployed, certain other participants seek a sense of purpose and try to spend their time engaging in menial tasks or social activities. Participants expressed an overall positive attitude towards employment which includes regarding work as being very important as well as remaining optimistic about their chances of finding a job. Coping with unemployment daily emerged as one of the struggles experienced by the participants in the study. The process of coping with unemployment daily includes utilising a variety of coping strategies to manage their unemployment as well as to manage negative feelings that emerge from being unemployed. The coping strategies indicated by the participants include listening to music, sleeping, reading the Bible, and talking to their friends or family members. Participants also revealed that they needed and received two types of social support from family and friends to help them cope with their unemployment predicament; including a need for emotional support and a need for instrumental support. Participants in the study experienced judgment by community and family members daily because of their unemployed status which includes stigmatising comments. These comments are internalised by participants which may exert a negative impact on their psychological well-being. Limitations of the study includes, participants could have answered the questions of the semi-structured guide in a socially desirable manner as well as the audio-recorded interviews were transcribed into Afrikaans and translated into English and as such, some of the meaning of what the participants had said could have been lost in the translation process. Recommendations for further research includes exploring whether perceived support have a greater beneficial effect on the psychological well-being of unemployed individuals than received support, as well as the role such types of support play in coping with unemployment. / Psychology / M.A. (Psychology)

This thesis considers two questions, "How children aged 12 to 15 years rethinking of biblical texts? And how can using the Philosophy for Children stimulate thinking about faith of children aged 12 to 15 years?" To answer these questions, I chose the qualitative research, which consisted in various discussions in selected focus groups. This dialogue was guided by the principles of philosophy for children. The theoretical part of my thesis deals with the definition of important concepts, such as religious education, catechesis from the perspective of various documents of the Church and other educational programs, and specifying the key differences between these two concepts, define the structure and principles of philosophy for children, but also the historical development of this program. The practical part deals with the qualitative research in focus groups. This research includes discussion of selected focus groups, where individual statements are encoded and then included in the table of frequencies. According to these tables discussions is evaluated in terms of statements frequencies. Subsequently the content of discussions is also evaluated. The codes are divided into categories from which discussions are evaluated in the final summary with answers to the key questions.
