[pt] Em geral, o movimento de corpos se dá em ambiente com barreiras podendo ocorrer colisões. Para que seja possível fazer previsões da dinâmica é necessário saber o que acontece quando um corpo colide. O problema é portanto: conhecida a dinâmica do corpo pré-colisão e as propriedades dos corpos que colidem, prever a dinâmica pós-colisão. Os primeiros trabalhos publicados sobre o assunto datam de 1668 e, até 1984,os modelos existentes pareciam satisfatórios. Porém a aplicação de um desses modelos a um problema simples apresentou geração de energia. Desde então, um grande número de trabalhos tem aparecido na literatura. A tese trata de problema de colisões planas, discute criticamente os modelos da literatura comparando-os através de uma generalização por nós desenvolvida e propõe um novo modelo que engloba alguns dos modelos da literatura. Mostramos os principais problemas de alguns dos modelos e discutimos questões de existência e unicidade. Simulações feitas num programa por nós desenvolvido são apresentadas e ajudam a entender a influência dos coeficientes constitutivos. A validação dos resultados é realizada através de resultados experimentais colhidos da literatura. / [en] In general the motion of a body takes place in a confined environment and collision of the body with the containing wall is possible. To predict the dynamics of a body in this conditions one must know what happens in a collision. The problem is then: known the pre-collision dynamics of the body and the properties of the body and the wall one want to predict the post-collision dynamics. This problem is quite old and it appeared in the literature in 1968. Up to 1984 it seemed that Newton model was enough to solve the problem. But it was found that this was not the case and a renewed interest in the problem appeared. This thesis treats the problem of plan collisions of rigid bodies and tries to classify the differents models and to compare them. A new model is presented and old results are shown in a new framework.

A dissertation submitted to the Faculty of Education in fulfillment of the requirements for the Degree of Master Of Education in the Department of Foundations Of Education at the University Of Zululand, 2018 / This study was about the role awareness of school governing bodies in the recruitment of teachers in UMkhanyakude District. The objectives of this study were: to determine the role of the school governing bodies in the recruitment of teachers in the UMkhanyakude District, to establish whether the school governing bodies in UMkhanyakude are able to perform the task of teacher recruitment and to determine the type of challenges UMkhanyakude District SGBs encounter when recruiting teachers. This was a qualitative research study exploring how SGBs in UMkhanyakude perform their duties regarding teacher recruitment and selection. Purposive sampling was chosen. The SGBs were a target group from 10 schools that were sampled and 10 participants participated. Data collected revealed that there are many challenges the SGBs face in teacher recruitment and selection. The challenge of selecting appropriate teachers was seen as the root cause of all other problems encountered in this critical function SGBs are entrusted with. SGBs were able to point out areas of development like: the role each constituency has to play in the interview committee, the code of conduct for educators, training on recruitment requirements and the human relations and communication. Some of the recommendations made included that the District must provide tailor-make continuous training based on needs and demand. The study also recommends translation of recruitment documents to help them understand. It was also recommended that the appointment of principals should be delegated to the district and not to SGBs. Newly appointed teachers should serve on probation before their permanent posts are confirmed. It was recommended that similar research should be undertaken with a bigger sample and it should be expanded to embrace other districts to increase validity and reliability of results.

Over the past several years, the physical appearance of pregnant and new mothers has been evolving within Western society. In particular, celebrity mothers who are templates for contemporary ideals within society (Tyler 2011) experience heightened levels of surveillance and normalizing practices. The shifting ideal, maternal form illustrates how the bodies of women continue to be subjected to discipline and control within society. Furthermore, the flourishing of consumer culture within some neoliberal societies pressures women to consume in order to fully realize their maternal identity. Increased articulation of individual identity through consumption, coupled with increasingly specific appearance standards, narrow the scope of what idealized motherhood embodies. In order to best investigate the issue of the shifting, ideal maternal form, various issues of tabloid magazines will be analyzed. Relying on social constructionism in conjunction with Foucault’s theories of the disciplining of docile bodies and biopower, along with Lyotard’s desire-based, libidinal economy, the literature on the public presentation of maternal bodies will be analyzed with focus on newly developed, rigorous appearance and fitness standards for mothers. Additionally, how these disciplinary practices function within neoliberal climates that champion desire-based consumption, freedom, liberty, individualism and self-subjectification will also be investigated. A cultural analysis of thirty-seven tabloid publications from 2012 to 2013 will be examined for both visual and written discourse pertaining to the cultural construction of ideal motherhood. Through this analysis the interplay between the two seemingly contradictory messages of excessive, desire-based consumption and restrictive, corporeal discipline will be explored in order to gain a better understanding of how these incongruous scripts affect the lives of mothers today. / Thesis (Master, Sociology) -- Queen's University, 2013-09-26 13:25:26.234

Since the new dispensation, all stakeholders in the school are expected to play an active role in the governance of schools. It is not the responsibility of government alone to see that schools are up and running. Parents, educators, non-teaching staff, learners (in Secondary Schools) and the community must also share their ideas on how the school is to be administered. This study has focused on the knowledge that the School Governing Bodies (SGB's) should posses in relation to legislations and the application of the knowledge make an impact in the administration and management of the school in the Klerksdorp-area. For schools to function effectively, the School Governing Bodies need to know that the Constitution (Act 108 of 1996) is the supreme law that has an impact in all education legislations, policies and regulations. Therefore, whatever school policy is to be developed should take cognizance of the Constitution. Central to the study is the SGBs' understanding of their roles and functions as stipulated in the Schools Act, (Act 84 of 1996) to avoid conflict of interest and administer the school efficiently and effectively. It is expected that the SGBs should transfer their knowledge into action by formulating policies that govern the school. By formulating school policies the SGB will then be able to have an influence since clear directions will be stipulated in the school policy on how the school is to be managed and administered. School Governing Bodies, as governors of the school are also accountable to people that elected them. It is their responsibility to provide feedback to their constituency and to inform them on the progress made. / Thesis (M.

The UKSG was a government-funded initiative that provided a high-quality, multi-sport event for the UK s elite young athletes of school age over a six-year period. At time of investigation, the event addressed six objectives (both developmental and operational in focus) through eight Olympic sports. Operational targets ensured that athletes were selected to compete at the UKSG. Developmental targets were indirectly linked to the event and made use of the UKSG profile to drive forward other youth related projects, such as the National Competition Framework (NCF). This study explored the outcomes of these objectives, whilst understanding the relationship between the Youth Sport Trust (YST) and eight sports, and locating the implementation of the UKSG within a broader analysis of the policy process for youth / school sport. The study utilized various policy process and implementation concepts to support analysis of findings. In particular, bottom-up and top-down theories of policy implementation and the advocacy coalition framework, policy networks and multiple streams approaches proved particularly useful as heuristic devices or useful points of comparison in the analysis of stages of policy process. The findings from the three case study sports (supported by the data collected from the five other investigated sports) made for interesting conclusions in relation to the three research questions: 1). What are the key impacts of the UKSG on the competition structures of the eight sports? 2). What is the relationship between the key organisations involved in the UKSG and the NCF? And 3). What is the perceived role of each of the organisations involved in the UKSG and the NCF? Through investigating the eight sports approach to the six UKSG objectives, empirical evidence was collected that related specifically to the sport s approach to youth competition and their newly established NCF (objectives two and three). Evidence identified these objectives as the most challenging of the six to address, due to the looseness of their definition and scope for reinterpretation across and within the sport organisations. With this flexibility came differences in inter-organisational power (between home country NGBs and School Sport Associations) and therefore policy implementation. This inevitably led to mismatches in policy expectations of the YST and policy outcomes delivered by the sports. The study moves on to reveal that the six UKSG objectives proved capable of challenging, and in some cases, changing NGB behavior, albeit through several different implementation approaches. In particular, the UKSG was a programme that supported the positive development of home country NGB and School Sport Association communication and working practices.
