The target audience is made up by professionals from the insurance market working for insurance brokers and insurance companies. The research was performed in two parts: quantitative and qualitative. The data for the quantitative research was collected through multidimensional model scale of affective, instrumental and normative commitment (Meyer & Allen, 1991), applied to 188 participants. The data of the average comparison analysis based on the T-Student test technique did not show statistically significant difference. The second part, the qualitative research, involved 11 interviews with employees from the industry in order to identify the reasons why the employees develop the commitment with each of the two types of the insurance market organizations. The research data obtained were analysed by using a content analysis technique and resulted in the model of background of insurance industry organizational commitment. It was found that the background of the affective commitment in insurance brokers is formed by the organizational climate, by the perception of justice and by the Human Resources policies and that the Human Resources policies predict the instrumental behaviour. In the insurance companies, it was found the affective commitment background are the organizational climate, the perception of support and the Human Resources policies and that the Human Resources policies predict the instrumental and normative commitment. These results contribute significantly for the management of people in the Brazilian insurance industry. / O objetivo principal deste trabalho é compreender quais fatores influenciam no comprometimento de corretoras de seguros e seguradoras, e mais especificamente: a) medir e comparar os indicadores de comprometimento dos funcionários de corretoras de seguros e seguradoras em três dimensões (afetiva, instrumental e normativa); b) analisar quais os fatores que mais influenciam cada dimensão do comprometimento no setor de seguros; c) comparar as diferenças e semelhanças dos fatores que influenciam o comprometimento em seguradoras e em corretoras. O público-alvo é formado pelos profissionais do mercado de seguros que atuam em corretoras de seguros ou seguradoras. A pesquisa foi realizada em duas partes: quantitativa e qualitativa. Os dados da pesquisa quantitativa foram colhidos por meio da escala do modelo multidimensional do comprometimento afetivo, instrumental e normativo (Meyer & Allen, 1991), aplicada em 188 participantes. Os dados da análise de comparação de médias pelo teste T-Student não apontaram diferença estatisticamente significativa. A segunda parte, qualitativa, envolveu 11 entrevistas com funcionários do setor a fim de identificar os motivos que levam os funcionários a desenvolver o comprometimento com cada um dos dois tipos de organizações do mercado de seguros. Os dados da pesquisa obtidos foram analisados utilizando-se a técnica de análise de conteúdo e resultaram no modelo de antecedentes do comprometimento organizacional do setor de seguros. Foi constatado que os antecedentes do comprometimento afetivo em corretoras de seguros são formados pelo clima organizacional, pela percepção de justiça e pelas políticas de recursos humanos, e que as políticas de recursos humanos predizem o comportamento instrumental. Nas seguradoras, constatou-se que os antecedentes do comprometimento afetivo são o clima organizacional, a percepção de suporte e as políticas de recursos humanos, e que as políticas de recursos humanos predizem os comprometimentos instrumental e normativo. Esses resultados contribuem significativamente para a gestão de pessoas do setor de seguros no Brasil.

This thesis aims to analyze the systems of education of employees in private companies, specifically in a company that is conducting in the insurance busines and their employees have very high expectations. Poorly and unprofessionaly led training programes for new and existing employees, may have improving effect on the development of these employees work as well as personal, and thus have a negative impact on the future of such employee in the company. Such a situation leads to an increase in fluctuation of costs that are associated with the costs of recruitment, training staff, as well as payroll and other expenses.

The following work was developed in the concentration area of “History, Culture and Power” in the research line “Integration, Politics and Frontier” of the masters course of the Post Graduated Program in History from the Federal University of Santa Maria (UFSM), with support from CAPES scholarship. The goal is to enquire about forms of power’s social construction and apropriation of resources from the elites in an open frontier region in the end of the XVIII century and in the begin of XIX centuty. The study was elaborated from the trajectory analysis of a potentate located in Rio Grande de São Pedro, José de Abreu - Barão do Serro Largo. In this sense, we had thought about his role as a mediator, that adjusted to the local reality, was able to establish relations with the large and multi-ethnic population that inhabited the frontier, being one of the links connecting the region to the Portuguese administrative network. It was possible to perceive, therefore, that Abreu's social ascencion had been allowed by the opening of the frontier after the conquest of the Missions in 1801. The conquered territory opened spaces for the insertion of new elites, who took field’s possession and organized spaces of command in new frontier. Abreu constructed his military store from a series of factors, among which stood out the alliance with the indigenous local population (guaranis from the Missions and groups of charruas). Besides to the relationship with the groups of military and militiamen officers who went to that region, receiving land that was distributed by José de Abreu, in exchange, mainly, by the military services. It was also possible to verify, in the same way, that these groups were very integrated. Abreu also managed to establish close ties to the Court, which made possible his appointment to the position of Governor of Arms, and his projection to a command space within the province. / O presente trabalho foi desenvolvido na área de concentração “História, Cultura e Poder” na linha de pesquisa “Fronteira, Política e Sociedade” do curso de mestrado do Programa de Pós graduação em História da Universidade Federal de Santa Maria (UFSM), com auxílio da bolsa CAPES. O objetivo é investigar as formas de construção social do poder e de apropriação de recursos das elites em uma região de fronteira aberta entre fins do século XVIII e início do século XIX. O estudo foi construído a partir da análise da trajetória de um potentado do Rio Grande de São Pedro, José de Abreu- o Barão do Serro Largo. Nesse sentido, pensou-se seu papel como um mediador que, ajustado à realidade local, pôde estabelecer relações com a ampla e multiétnica população que habitava a fronteira, sendo um dos elos a ligar a região à malha administrativa portuguesa. Foi possível perceber, assim, que a ascenção social de Abreu fora permitida pela abertura da fronteira a partir da conquista das Missões em 1801. O território conquistado abria espaços para a inserção de novas elites, que se apropriavam de campos e organizavam espaços de mando na nova fronteira. Abreu contruíu seu cabedal militar a partir de uma série de fatores, dentre os quais se destacavam a aliança com a população local indígena (guaranis egressos das Missões e os grupos de charruas). Além do relacionamento junto aos grupos de oficiais militares e milicianos que se deslocavam para essa região, recebendo terras que eram distribuídas por José de Abreu, em troca, principalmente, dos serviços militares. Foi possível constatar, da mesma forma, que esses grupos estavam muito integrados. Abreu ainda conseguiu estabelecer vínculos próximos à Corte, que tornaram possíveis sua nomeação para o cargo de Governador das Armas, e sua projeção a um espaço de comando no âmbito da província.

A modulação utilizada para avaliar o desempenho dos códigos obtidos é a p ? PSK. Códigos LDPC definidos sobre corpos finito de inteiros possuem estrutura algébrica bem definida, são facilmente feitos invariantes a rotação de fase da portadora no processo de modulação e podem ser feitos mais curtos que os seus equivalentes binários. O método de decodificação iterativa utilizada na avaliação do desempenho destes códigos é uma adaptação do algoritmo SISO (Soft Input Soft Output) proposto por P. G. Farrell e J. Moreira [1] e [2] que utiliza a distância euclidiana como parâmetro de confiabilidade dos símbolos da palavra código recebida. Os códigos LDPC utilizados na simulação da codificação e decodificação do canal de comunicação são definidos para o campo de inteiros Z5. O canal de comunicação foi modelado com um ruído gaussiano branco aditivo (AWGN - Additive White Gaussian Noise) e com um desvanecimento Rayleigh. Ambos modelos de canal utilizam a modulação 5 ? PSK. O desempenho dos esquemas de codificação LDPC definidos sobre Z5 foram analisados de modo comparativo com sistemas equivalentes de codificação binários e quartenários. Palavras-chave: Códigos LDPC não binários, corpos de inteiros módulo-p, modulação p ? PSK, canal AWGN, desvanecimento Rayleigh / Abstract: On this disertation we present a study on the feasibility of constructions and use of LDPC (Low Density Parity Check) codes defined over finite fields of integers modulo p, where p is a prime integer. The modulation used to evaluate the performance of the codes is obtained from a p ? PSK. LDPC codes defined over finite field of integers have well defined algebraic structure, they can be easily made invariant to phase rotation in the carrier modulation process, and can be made shorter than its binary equivalent. The iterative decoding method used during the evaluating the performance of these codes is an adaptation of the algorithm SISO (Soft Input Soft Output) proposed by P. G. Farrell and J. Moreira [1] e [2] that uses the Euclidean distance as the reliability of the parameter code word symbols received. The LDPC codes used during the simulation of encoding and decoding of the communication channel are defined for the whole body of Z5. The communication channel was modeled as additive white Gaussian noise (AWGN) and Rayleigh fading. Both communication channel models used modulation 5 ? PSK. The performance of LDPC coding schemes defined over Z5 were analyzed comparatively with equivalent systems of binary and quaternary encoding.

Um processo que auxilia na evolução é o splicing alternativo, consistindo de uma codificação bastante conveniente, que a partir de um único gene consegue gerar várias proteínas, combinando éxons e íntrons de diferentes formas, aumentando assim a capacidade proteômica. Várias pesquisas buscam uma melhor compreensão dos mecanismos envolvidos no splicing altenativo e quais as consequências dos erros cometidos durante este processo. Este trabalho tem como objetivo principal analisar as propriedades matemáticas envolvidas no splicing alternativo por meio dos códigos corretores de erros. Os códigos (BCH) foram utilizados nos casos que ocorreram erros de substituição de nucleotídeos e os códigos de Varshamov-Tenengolts nos casos que ocorreram erros de inserção e deleção de nucleotídeos. Neste trabalho verificamos a possibilidade reproduzir matematicamente o splicing alternativo de acordo com as restrições biológicas. Para atingir este objetivo, consideramos o gene TRAV7 presente no genoma humano e o gene Hint-1 presente no nematoide Caenorhabditis Elegans / Abstract: During millions of years mankind, animals and plants have transformed themselves, continuing to evolve in order to adapt themselves to the environment. A process that helps in the evolution is the alternative splicing, consisting of a rather suitable codification, that manages to produce several proteins from a single gene, combining exons and introns of different forms, in this way increasing the proteomic capacity. Several surveys search for both a better understanding of the mechanisms involved in alternative splicing and the consequences of errors committed during this process. This study has as its main objective to analyze the mathematical properties involved in the alternative splicing through correcting codes of errors. The codes (BCH) were used in the cases when errors of substitution of nucleotides occurred and Varshamov-Tenengolts codes in the cases when errors of insertion and deletion of nucleotides occurred. In this study we verified the possibility of reproducing mathematically the splicing alternative in accordance with the biological restrictions. To achieve this objective we considered the gene TRAV7 present in the human genome and the gene Hint-1 present in the nematode Caenorhabditis Elegans / Mestrado / Telecomunicações e Telemática / Mestre em Engenharia Elétrica

Magister Philosophiae - MPhil / The ever increasing regional and global trade competition has manifested itself in a growing number of non-standard forms of employment including the increasing use of "temporary employment services" (or “labour brokers” as commonly referred to). Labour brokers enter into employment relationships as third parties with client companies to supply employees through a commercial contract. These labour services usually fall outside the regular twoparty contract of employment defined under existing labour laws and thus the employees are not covered by that law. Labour brokers have been labelled as “the re-emergence of new apartheid strategy” and “modern slavery” by some quarters in labour sectors of Namibia and South Africa. Trade unions, particularly, have led the most vocal resistance against labour brokers in both countries. They argue that, like previous apartheid contract labour systems, labour brokers today erode standards for decent working conditions and weaken union representations in the workplace. Thus unions have repeatedly sent strong calls to lawmakers to amend existing labour laws and „forever put labour broking in its grave where it belong‟1. On the other hand, employers have argued that recent forces of globalisation demand flexible employment strategies and banning labour brokers will make it more difficult for local businesses compete profitably globally via flexible short term employments and can lead to losses of many job opportunities.2 It is against this background that I will argue that current labour laws should be amended to define and regulate labour brokers more closely and compel them to recognise workers rights and conditions as equal as those of standard employees. But first, I will highlight some socio-economic indicators influencing the labour markets in South Africa and Namibia, including the history of worker‟s rights under the contract labour systems in both countries. Second, I will look at some of the expressed exploitive conditions resulting from the use of labour brokers and also look at some reasons why businesses engage labour brokers. Thereafter I will point out some of the reasons why trade unions have called for a total ban on labour brokers. I will then discuss the difficulty of banning labour brokers, including the constitutional challenge in the landmark case of African Personnel Services v Government of the Republic of Namibia3. Lastly i will expand on the ruling by the Namibian Supreme Court of Appeal (NSA) recommending a regulatory approach in line with the International Labour Organisation‟s (ILO) conventions on third-party employments. / South Africa

Magister Philosophiae - MPhil / This study outlines human dimensions in the hake sector in South Africa in terms of hake fish workers. The hake fish workers condition of employment, security of employment, social security issues, remunerations and their living conditions forms part of the social, economic and political dimensions in hake fisheries. The need for ensuring sustainable long-term utilisation of the hake resource and to manage, prevent and reduce all adverse effects of harvesting the hake stock through knowledge based intervention is crucial to this study. Sustainable fisheries management can use the working and living conditions of fish workers as indicators for effective management of fisheries. Fish workers issues, which include their conditions of service, contractual agreements, work safety, income, working hours and other human dimensions, may have an effect on the effective sustainable management. Ecosystems approaches takes into consideration the human dimensions and ecological consideration for effective fisheries management. Knowledge of the historical and economic importance of the hake sector is crucial for the planning and future of the fisheries. Applying the concept of the ecosystems approaches to hake fisheries management is also critical in understanding the human dimensions in hake fisheries. The qualitative methodology of field work was used in understanding the human dimensions in commercial hake fisheries. The investigation into the fish workers labour issues and living conditions through a field work highlighted that the labour issues such as type of employment (permanent or casual), conditions of employment (social security, regulated hours of work, good working conditions), stagnation in terms of promotion, remuneration and issues surrounding labour brokers are some of the social issues in the hake sector. The living conditions of fish workers, stagnation and improved remuneration should be attended to in the sector. Fish workers in the hake sector rely on wages for their livelihood. Workers’ participation in decision-making at governance level should be enhanced for effective governance in the fisheries
