O objetivo ? determinar o circuito hamiltoniano que resulte em um custo final m?nimo, considerando a penaliza??o paga em cada troca de ve?culos no tour. A penaliza??o ? o custo de retornar o carro at? a cidade onde foi alugado. O PCA est? classificado como um problema NP-dif?cil. O presente trabalho estuda a variante mais usada na literatura do PCA que ?: completo, total, irrestrito, sem repeti??o, livre e sim?trico. O foco da pesquisa s?o os procedimentos h?bridos que combinam meta-heur?sticas e m?todos baseados na Programa??o Linear. S?o hibridizados: algoritmos cient?ficos (ScA), descida em vizinhan?a vari?vel (VND), busca local adaptativa (ALSP) e uma nova variante do ALSP chamada busca local adaptativa iterativa (IALSP). As seguintes t?cnicas s?o propostas para lidar com o PCA: ScA+ALSP, ScA+IALSP e ScA+VND+IALSP. ? proposto um modelo de programa??o inteira mista para o PCA o qual ? usado no ALSP e no IALSP. Testes n?o param?tricos s?o usados para comparar os algoritmos em um conjunto de inst?ncias da literatura. / The Traveling Car Renter Salesman Problem, or simply Traveling Car Renter Problem (CaRS), is a generalization of the Traveling Salesman Problem (TSP) where the tour can be decomposed into contiguous paths that are traveled by different rented cars. The objective is to construct a minimal cost Hamiltonian circuit, considering the penalty paid for changing cars in the tour. This penalty is the cost of returning a car to the city where it was rented. CaRS is classified as an NP-hard problem. This work studies the CaRS version classified as: complete, total, unrestricted, with no repetition, free and symmetric. This research is focused on hybrid procedures that combine metaheuristics and methods based on Linear Programming (LP). The following methods were investigated: scientific algorithms (ScA), variable neighborhood descent (VND), adaptive local search (ASLP) and a new variant of ALSP called iterated adaptive local search (IALSP). The following techniques are proposed to deal with CaRS: ScA+ALSP, ScA+IALSP and ScA+VND+IALSP. A mixed integer programming model is proposed for CaRS which was used in the ALSP and IALSP. Non-parametric tests were used to compare the algorithms within a set of instances from the literature.

This research investigates the Neo-Baroque aesthetic of excess in contemporary South African art, and explores reasons for the emergence of this style. It investigates artists who use their bodies as a site of resistance, to contest or reconstruct the dominant social values which establish differences between bodies to place them within the marginal position of ‘Other’. This investigation relates to post-colonial concerns. The artists’ exploitation of the Neo-Baroque aesthetic of excess as a comment on social concerns reveals a sense of crisis within South African society, similar to the conditions from which the seventeenth century Baroque style evolved. Neo-Baroque aesthetics of excess manifest in a variety of ways, and are particularly evident when artists transgress social boundaries placed on the body through abject and erotic associations. Excess ultimately arises from complexity, as hybrid art forms are created from the combination of media and content found within the art work. / Dissertation (MA)--University of Pretoria, 2012. / Visual Arts / unrestricted

The study was based on Kohlberg's moral development Theory, which presents three stages of moral development: pre-conventional (stages 1 and 2), conventional (stages 3 and 4) and post-conventional (stages 5 and 6), and on Hofstede's Culture Theory, which presents the following dimensions: power distance, collectivism versus individualism, femininity versus masculinity, uncertainty avoidance and long-term orientation versus short term orientation. The results were obtained through a descriptive analysis, ANOVA test, equality of proportion test, Pearson's correlation, confidence interval for average and p-value. The variables related to moral development, age, gender, religion and professional experience did not present statistically meaningful difference in the regions surveyed, what did not occur with the variable education, which proved to be a strong and consistent variable when compared to moral development. This study also aimed to verify if Hofstede's cultural dimensions presented significance between the studied regions. Difference was found in the following dimensions: power distance, individualism and long-term orientation. It is also possible to observe that the p index of moral development presents a statistically meaningful relation with the regions. Another important find in this study is that there is no statistically meaningful relation between the p index of moral development and the cultural values among the students that participated in this research in the regions surveyed. / Esta pesquisa teve como objetivo analisar, considerando-se as diversidades culturais do Brasil, se h?? diferen??a estatisticamente significativa em rela????o ao n??vel de desenvolvimento moral dos estudantes de gradua????o de Ci??ncias Cont??beis de diferentes Institui????es de Ensino Superior. Para tanto, utilizou-se como base a Teoria do desenvolvimento moral de Kohlberg, que postula em sua teoria tr??s n??veis de desenvolvimento moral: o pr??-convencional (est??gios 1 e 2), o convencional (est??gios 3 e 4) e o p??s-convencional (est??gios 5 e 6), e a Teoria da Cultura de Hofstede, que est?? definida nas seguintes dimens??es: dist??ncia do poder, coletivismo versus individualismo, feminilidade versus masculinidade, controle da incerteza e orienta????o de longo prazo versus curto prazo. Os resultados foram obtidos atrav??s de an??lise descritiva, teste ANOVA, teste de igualdade de propor????es, correla????o de Pearson, intervalo de confian??a para m??dia e p-valor. As vari??veis relacionadas com o Desenvolvimento Moral, idade, g??nero, religi??o e experi??ncia profissional, n??o tiveram diferen??as estatisticamente significativas nas regi??es pesquisadas, diferentemente da vari??vel educa????o, que comprovou ser uma vari??vel forte e consistente quando comparada com o desenvolvimento moral. Buscou-se ainda verificar se as dimens??es culturais de Hofstede tinham ou n??o signific??ncia entre as regi??es pesquisadas. Constatou-se diferen??a nas dimens??es dist??ncia do poder, individualismo e orienta????o a longo prazo. Nota-se ainda que o ??ndice p do desenvolvimento moral possui rela????o estatisticamente significante entre as regi??es. Outro achado importante nesta pesquisa foi que n??o h?? rela????o estatisticamente significativa entre o ??ndice p do desenvolvimento moral com os valores culturais entre os estudantes das regi??es pesquisadas.
