La théorie des processus de branchement multi-type en environnement i.i.d. est considérablement moins développée que dans le cas univarié, et les questions fondamentales ne sont pas résolues en totalité à ce jour. Les réponses exigent une compréhension profonde du comportement des produits des matrices i.i.d. à coefficients positifs. Sous des hypothèses assez générales et lorsque les fonctions génératrices de probabilité des lois de reproduction sont “linéaire fractionnaires”, nous montrons que la probabilité de survie à l’instant n du processus de branchement multi-type en environnement aléatoire est proportionnelle à 1/√n lorsque n → ∞. La démonstration de ce résultat suit l’approche développée pour étudier les processus de branchement uni-variés en environnement aléatoire i. i. d. Il utilise de façon cruciale des résultats récents portant sur les fluctuations des normes de produits de matrices aléatoires i.i.d. / The theory of multi-type branching process in i.i.d. environment is considerably less developed than for the univariate case, and fundamental questions are up to date unsolved. Answers demand a solid understanding of the behavior of products of i.i.d. matrices with non-negative entries. Under mild assumptions, when the probability generating functions of the reproduction laws are fractional-linear, the survival probability of the multi-type branching process in random environment up to moment n is proportional to 1/√n as n → ∞. Techniques for univariate branching process in random environment and methods from the theory of products of i.i.d. random matrices are required.

Composto por: acesso à saída, a saída em si e a descarga, podendo ser concebido de formas variadas, porém sempre visando à segurança dos usuários e da comunidade local diante dos desafios que as cidades enfrentam. Ao antever falhas do sistema de prevenção e proteção contra incêndio, é afirmada a importância do correto planejamento, desenvolvimento, execução e manutenção do projeto de evacuação. As variáveis envolvidas nesse processo e as noções de comportamento humano perante um incêndio sofrem influência da velocidade de saída das pessoas, da resposta ao tempo de alarme e das reações em decorrência da fumaça. O presente trabalho procura expor os aspectos a serem analisados num processo de evacuação, ligados aos sistemas de saída de emergência. A análise em questão é uma edificação escolar de ensino técnico, de nível médio profissionalizante, que concentra uma população de idade variável, inclusive classificação de riscos diferentes. O projeto é de uma escola de ensino técnico de nível médio profissionalizante, com capacidade para 1200 alunos, com blocos separados por função, sendo o bloco administrativo/pedagógico disposto em dois pavimentos, principal objeto de estudo. O modelo de projeto desenvolvido é proposto para aplicação a nível nacional, já implantado no estado do Ceará, em 2011. Partindo do diagnóstico de utilização das diretrizes contra incêndio, foi realizada a verificação de aplicação do projeto nos Estados de Santa Catarina e do Rio Grande do Sul, e a simulação através do software Pathfinder para investigação das principais variáveis envolvidas no processo de evacuação. Poucas foram as diferenças notadas entre as exigências das normativas. O número de alunos por sala de aula foi ditado pela lei e parecer dos sistemas de educação estaduais. Um projeto proposto ao fortalecimento de instituições nacionais deve atentar para o cumprimento do exigido nas normativas, verificando o funcionamento do projeto com auxílio do software. Entretanto é necessária uma revisão projetual para atendimento do mínimo exigido para o uso efetivo das saídas de emergência. / The case study developed in the present work is related to the emergency exit system. It compounds: access to exit, exit itself and the discharge, it can be conceived in various ways, but always aiming at the safety of users and the local community in the face of the challenges facing cities. When anticipating failures of the fire prevention and protection system, the importance of correct planning, development, execution and maintenance of the evacuation project is affirmed. The variables involved in this process and the notions of human behavior in the face of a fire are influenced by people's exit velocity, response time to alarm and reaction due to the smoke. The present work tries to expose the aspects to be analyzed in an evacuation process, linked to emergency exit systems. The analysis in question is a school building of technical education, of medium professional level, that concentrates a population of variable age, including classification of different risks. The project consists of a technical secondary school with a capacity for 1200 students, with blocks separated by function, the administrative / pedagogical block being arranged in two floors, the main object of study. The developed project model is proposed for implementation at the national level, already implemented in the state of Ceará, in 2011. Based on the diagnosis of the use of fire directives, a verification of the application of the project was carried out in the states of Santa Catarina and Rio Grande and the simulation through Pathfinder software to investigate the main variables involved in the evacuation process. Few were the differences noted between the requirements of the regulations. The number of students per classroom was dictated by the law and opinion of the state education systems. A project proposed for the strengthening of national institutions, must pay attention to the fulfillment of the required in the regulations, verifying operation of the project with the help of software. However, a design review is required to meet the minimum required for the effective use of emergency exits.

Aims: To describe the health behaviours and health of those described as health workers; explore the possible effect of work on their health and early exit from the workforce; and make comparisons to other occupational groups. Study design and methods: The aims were addressed through 5 studies incorporating both a literature review and secondary analyses of existing data sets using both cross-sectional and longitudinal approaches. Data was collected on demographic data, health, health behaviours, impact of health on work, and workforce exit. Descriptive analysis was used to summarise the comparisons and binary logistic regression and Cox proportional Hazard models were applied to give more in depth analysis. Results: A disability was reported by 11.1% of nursing and midwifery professionals compared to 7.1% of health professionals and 16.8% of caring personal service workers. One in four nursing and midwifery professionals reported a health problem that affected the amount and type of work they could undertake compared to one in two workers categorised in other occupations. Predictors of poor health included demographics, occupation and health behaviours. Age appeared to be the only significant predictor of workforce exit in the study. Compared to nursing and midwifery professionals, those identifying themselves as nursing auxiliaries, care assistants, and home carers were significantly more likely to leave the workforce before retirement age (p ˂ 0.001).Conclusion: The findings suggest that nurses' health is poorer than some other health professionals and that they engage in a number of health behaviours known to lead to health problems. Occupation plays a direct or indirect role on health and early exit from the labour market; however, the inter-relationship appears complex. Further research is needed to understand, address and improve the health of nurses and care workers. Factors that explain auxiliaries', care assistants' and carers' workforce exit also require further examination.

The objective that guided this study was to know and to interpret the relations between the formation in the course of Agronomy and the work of graduates of classes 2010 and 2011 IF Goiano - Morrinhos Campus, with a view to an analysis of public policies for higher education in Brazil. Considering that the Federal Institutes of Education, Science and Technology prepare their students for entry into the labor market, it becomes important to know the reality of graduate students. Among the different courses offered by the research institution, what attracted the attention was the baccalaureate in Agronomy. This is because it meets the demand of much of Brazil, since the economy of the country, and especially of the Center-West region, is based on agricultural and livestock activities. The research problem can be described from the question: Did the higher education in agronomy interfere with the economic, social and professional life of the graduates of the 2010 and 2011 classes of the Goiano IF - Campus Morrinhos? As regards the methodology, was used a quantitave research, based on the method of dialectical historical materialism, to capture the real movement of thought, in order to understand the relationships between the parts and the whole, in view of the totality, the contradiction, the mode of production and the class struggle. It implies, therefore, to take the object of analysis as part of a historical totality that constitutes it, where the mediations between the field of particularity and its relation to a certain universality are established. To capture part of the reality, we used documentary and empirical research, as well as secondary data provided by the National Institute of Studies and Educational Research "Anísio Teixeira", by the Brazilian Institute of Geography and Statistics, among others. In the empirical research, a questionnaire was applied with semi-structured questions, made available through the Survey Monkey tool. From the universe of 43 graduates of the two groups investigated, 40 participated in the research. The theoretical bases that guide this dissertation are supported by studies by Antunes (1999), Azevedo (1997, 2010), Bianchetti (2001), Bobbio (1982, 1987), Campos (2014), Carnoy (1990), Chauí (1980, 2004), Coutinho (1981, 1989), Durham (2006), Engels (1985), Fávero (2006), Freire (2003), Frigotto (1989), Gentili (1995), Ianni (1980), Marx (1983, 1989, 2004), Oliveira (2014), Paro (1997, 1999), Pinto (2010), Saviani (1991, 2007), among others. The results showed that 80% of the graduates who participated in the research are male and 20% female, reinforcing the male presence in the agronomist profession. The time elapsed between graduation and insertion in the labor market was less than 1 year for 59% of the respondents. The expectations of graduates regarding initial training and work were confirmed for most of the graduates, since 60% of the interviewees revealed that they are inserted in the job market and acting in the area of their training. The survey indicated that 65% of graduates had no income before graduation, and 30% reported receiving 1 to 2 minimum salaries. The economic aspect changed after completing the course for 18% of respondents. Considering that at the beginning of the course 65% of respondents reported not receiving any income, the differential for most of these subjects was the completion of the higher education course. Regarding continuing education, this study showed that 64% of respondents stated that they had invested in continuing education after completing their undergraduate course / A presente pesquisa integra os estudos desenvolvidos na linha de Pesquisa Estado, Políticas e Instituições Educacionais do Programa de Pós-Graduação em Educação da Pontifícia Universidade de Goiás. O objetivo que norteou este estudo foi conhecer e interpretar as relações entre a formação no curso de Agronomia e o trabalho dos egressos das turmas de 2010 e 2011 do IF Goiano – Campus Morrinhos, com vistas a uma análise das políticas públicas de educação superior no Brasil. Considerando que os Institutos Federais de Educação, Ciência e Tecnologia preparam seus alunos para o ingresso no mercado de trabalho, torna-se importante conhecer a realidade dos egressos da graduação. Entre os diferentes cursos oferecidos pela instituição pesquisada, o que chamou a atenção foi o bacharelado em Agronomia. Isso porque ele atende à demanda de grande parte do Brasil, uma vez que a economia do país, e em especial da região Centro-Oeste, sustenta-se nas atividades agrícolas e pecuárias. O problema da pesquisa pode ser descrito a partir da indagação: A formação superior em agronomia interferiu na vida econômica, social e profissional dos egressos das turmas de 2010 e 2011 do IF Goiano – Campus Morrinhos? No que se concerne à metodologia, utilizou-se a pesquisa quantiqualitativa, fundamentada no método do materialismo histórico dialético, para captar o movimento real do pensamento, de maneira a se entender as relações entre as partes e o todo, tendo em vista a totalidade, a contradição, o modo de produção e a luta de classes. Implica, desse modo, tomar o objeto de análise como parte de uma totalidade histórica que o constitui, onde se estabelecem as mediações entre o campo da particularidade e sua relação com determinada universalidade. Para captar parte da realidade, foram utilizadas as pesquisas documental e empírica, além de dados secundários disponibilizados pelo Instituto Nacional de Estudos e Pesquisas Educacionais “Anísio Teixeira”, pelo Instituto Brasileiro de Geografia e Estatística, entre outros. Na pesquisa empírica, aplicou-se um questionário com perguntas semi-estruturadas, disponibilizadas por meio da ferramenta Survey Monkey. Do universo de 43 egressos das duas turmas investigadas, 40 participaram da pesquisa. As bases teóricas que orientam esta dissertação estão respaldadas nos estudos de Antunes (1999), Azevedo (1997, 2010), Bianchetti (2001), Bobbio (1982, 1987), Campos (2014), Carnoy (1990), Castelo (2012), Chauí (1980, 2004), Coutinho (1981, 1989), Durham (2006), Engels (1985), Fávero (2006), Freire (2003), Frigotto (1989), Gramsci (2011), Gentili (1995), Ianni (1980), Marx (1983,1989, 2004), Oliveira (2014), Paro (1997, 1999), Pinto (2010), Saviani (1991, 2007), entre outros. Os resultados mostraram que 80% dos egressos que participaram da pesquisa são do sexo masculino e 20% do sexo feminino, reforçando a presença masculina na profissão agrônomo. O intervalo de tempo transcorrido entre o término da graduação e a inserção no mercado de trabalho foi de menos de 1 ano para 59% dos respondentes. As expectativas dos egressos em relação à formação inicial e o trabalho se confirmaram para a maioria dos egressos, pois 60% dos entrevistados revelaram que estão inseridos no mercado de trabalho e atuando na área de sua formação. A pesquisa indicou que, antes da conclusão do curso superior, 65% dos egressos não tinham rendimentos, e 30% informaram que recebiam de 1 a 2 salários mínimos. O aspecto econômico sofreu alteração após a conclusão do curso superior para 18% dos entrevistados. Considerando que no início do curso 65% dos entrevistados informaram não receber nenhum rendimento, o diferencial para grande parte desses sujeitos foi a conclusão do curso superior. Em relação à formação continuada, este estudo mostrou que 64% dos respondentes declararam ter feito investimento na formação continuada após a conclusão do curso de graduação

Les systèmes multi-agents sont des systèmes dans lesquels des entités logiciellesappelées agents interagissent de façon autonome dans des environnements partagés. Ces dernièresannées, de nombreuses recherches sur les organisations multi-agents ont été menées etdivers modèles organisationnels ont été proposés. Cependant, ils n’offrent pas de solution pourune gestion effective de la problématique d’ouverture dans des organisations multi-agents normatives.Dans cette thèse, nous nous sommes intéressées à l’étude de cette problématique etdonc à la spécification des besoins relatifs à la mise en oeuvre de l’ouverture au sein d’organisationmulti-agent. Nous avons ainsi identifié trois propriétés caractéristiques de cette problématique: l’interopérabilité d’une organisation avec son environnement extérieur et interne, lagestion des entrées / sorties et la gestion du contrôle et de la régulation des agents. Pour répondreà ces propriétés, nous avons proposé un langage de modélisation d’organisation (OML)MOISE qui est une extension de Moise+. MOISE permet de spécifier de façon explicite lesprocessus d’entrée / sortie dans une organisation et notamment les exigences relatives auxmissions, buts, et rôles de l’organisation. Nous avons également proposé une infrastructure degestion d’organisation (OMI) ORA4MAS qui s’inspire du méta-modèle Agents et Artifacts(A&A). Nous avons défini le concept d’artefact organisationnel pour implémenter les fonctionnalitéscorrespondant aux spécifications du langage MOISE. Nos propositions ont été illustréesavec une spécification d’organisation de gestion de la construction d’un édifice. La miseen oeuvre des propriétés d’ouverture a été expérimentée avec la gestion des processus d’entrée/ sortie des agents, la négociation des clauses de contrat, la coordination des coopérations desagents à la réalisation des buts de construction d’un édifice, le contrôle des comportements desagents relativement aux normes de l’organisation ainsi que leur régulation. / Multi-Agent Technology concerns the development of decentralized and open systemscomposed of different agents interacting in a shared environment. In recent years, organizationhas become an important in this research field. Many models have been, and are still,proposed. While no concensual model emerges of these different works, it appears that theyall lack the ability to build open and normative organizations in the sense of management ofentry / exit of agents into organization but also decentralized control / regulation of the autonomyof the agents. In this thesis, our objective consists in the definition of a new modeladdressing these requirements. Ours reseaches allow us to extend theMOISE+ organizationalmodeling language (OML) in a new version namming MOISE. In this one we define an Entry/ Exit specification allowing to explicitly specify the ways in which the agents can enter orexit in or from an organisation by providing some requirements according to the missions, thegoals and the roles of the organisation. The organizational management infrastructure (OMI)ORA4MAS proposed take advantage of the Agents and Artifacts (A&A) approach. We definedthe Organizational Artifacts concept as the basic building block of our OMI for themanagement of organized and open MAS. To focus our study, the organizational artifacts willbe defined considering the OML specification of the MOISE model. We experimented ourproposal with the specification of an application aiming to manage the build of a house. Wethen experimented the management of the candidate agents to enter in the organisation and cooperatewith the other to build the house according to a specified social scheme, the specifiednorms and their contract clauses negociated when they will be admitted in the organisation.

Föreliggande uppsats undersöker hur industriföretag arbetar med att behålla och tillvarata kompetens vid omställningsarbeten. Studien utgår från en kvalitativ fallstudie som forskningsmetod, där dokument och 16 intervjuer utgör studiens empiri. Studien har en fallstudiedesign med flera analysenheter och studerar styrdokument, ledning, linjechef och medarbetare. Resultatet visar att företaget arbetat med en övergripande kompetensförsörjningsprocess som utgångspunkt vid omställningsarbetet. Studien visar även att bristande kompetensöverföringsstrategi och tid för kompetensöverföring har varit det största hindret för att tillvara kompetens. Studiens slutsatser är att industriföretaget använt en mixad kunskapsstrategi vid omställningsarbetet. Företaget har erbjudit strategier, verktyg och arbetssätt vid omställningsarbetet, däremot har förutsättningarna inte varit tillräckliga. Vid omställningen har därför informella tillvägagångssätt uppstått vilket representerat en god förutsättning i arbetet. Avslutningsvis synliggörs en bristande interaktion mellan analysnivåerna och utgör studiens praktiska implikationer. Företag kan bygga anpassade kompetensförsörjningsstrategier genom att förmedla informella tillvägagångssätt till ledningsnivå samt att inhämta kunskap om hur kunskapsöverföring sker i praktiken. / The study examines how manufacturing industries work to maintain and utilize competence during downsizing. This study is based on a qualitative case study using data of documents and 16 interviews and applies a single-case design with multiple units of analysis investigating documents, managers, line-managers and employees. The findings reveal that the company adopted a comprehensive competence process as the main procedure during downsizing. The findings expose a lack of knowledge transfer strategy and time identifies as the biggest obstacle to maintain knowledge. The conclusions represent that enterprises applies a mixed knowledge strategy during downsizing. Strategies, tools and procedures were available during the downsizing, but these conditions were not enough. Informal procedures unfold as a result of these insufficient conditions and facilitates knowledge retention. The study reveals a lack of interaction between the units of analysis, which represents the practical implications. Enterprises can build customized competence strategies by communicating informal procedures to management level as well as acquiring knowledge of how knowledge transfer take place in practice.

The purpose of this research was twofold. Since e-mentoring is relatively new, there have been very few studies that have explored the impact of an e-mentoring program on both the academic and psychological outcomes of its participants. In addition, there is little research on the quality of implementing, or what we will call the working quality, of an e-mentoring model. This study addressed both. First, the study examined whether or not e-mentoring had an academic and psychological impact on 32 high school students who were at-risk of dropping out of school. The students were enrolled in a GED Exit Option program at two technical centers in a large urban school district in Florida. Each student was matched with a mentor who was a business partner and involved with one or both of the technical centers in an advisory capacity. The students and mentors were randomly matched and never met face-to-face during the program. All of their communication and mentoring was done online using a secure e-mail program. Second, the working quality of the e-mentoring model was addressed. By using the design experiment methodology during the course of the study and examining the quality of each component of the e-mentoring model as it was being implemented, revisions were made as problems were identified during each component of the e-mentoring program. The structured e-mentoring model used was based on a review of the literature and specifically on the research of Single and Muller (1999). The students, mentors, and instructors who participated were co-participants in the design and analysis and provided input using surveys and focus groups at several intervals throughout the e-mentoring program. The design experiment approach was intended to help researchers deal with and learn from events in classrooms where it is impossible to control many variables and where the objective of the research is to refine a system (e.g., an e-mentoring program) or a curriculum. Analysis of the data showed there were no significant differences between the participants and the non-participants in the program as it related to self-esteem, career indecision, attendance, and academic achievement. However, the rich dialogue that occurred throughout the program allowed the researcher to examine the working quality of the program in progress. The modifications and improvements made to the e-mentoring process will provide an excellent foundation for future e-mentoring programs.

<p>Uppsatsen belyser vägen ur ett självskadande beteende där tre kvalitativa intervjuer har gjorts för att närma sig vändpunktsprocesserna. Även en självbiografisk bok har använts som empiriskt stöd. Syftet är att kunna urskilja hur vägen ut ur ett självskadande beteende kan se ut för olika personer. Det empiriska materialet belyses även utifrån Antonovskys teori om KASAM, Ebaugh Fuchs teori om exitprocesser samt tidigare forskning. De frågeställningar som ligger till grund för uppsatsen är följande: är det möjligt att kunna urskilja en vändpunkt (yttre och inre faktorer)? Vilken betydelse har personer i individens omgivning haft för vägen ut ur ett självskadande beteende? Hur har samhällets insatser hjälpt individen att ta sig ur sitt beteende? De slutsatser som kan konstateras är att det för samtliga intervjudeltagare samt i den självbiografiska boken går att urskilja någon form av vändpunkt. Utifrån de berättelser vi tagit del av kan vi konstatera att vändpunkter kan se väldigt olika ut. Ytterligare en slutsats är att samtliga kvinnor är eniga om att vårdinsatserna är för denna patientgrupp bristfällig eller ibland helt lyser med sin frånvaro. Det viktigaste i intervjudeltagarnas tillfrisknande är deras egen jagstyrka och motivation. Samtliga kvinnor har i dag nya hanteringsstrategier för att klara av livets motgångar och svårigheter.</p> / <p> </p><p>This thesis highlights self-harming behavior and the journey to recovery. To approach the turning point and the following process three qualitative interviews has been done. An autobiographical book has been used as an empirical data. The purpose is to distinguish how the journey to recovery can differ between diverse people. The empirical data has been illustrated by using Antonovskys theory sence of coherence, Ebaugh Fuchs process of roll exit and current research. The issued questions grounding the thesis are: is it possible to distinguish a turning point (outer and inner factors)? How important were the people surrounding the individual to find the way out? And how did society's efforts help the individual out of its behavior? The conclusions that are determined are that with all of the interviewed and the autobiographical book, a turning point can be discerned. From the stories given to us we can determine that the turning points can differ considerably. Yet another conclusion is that all of the women agree that the care effort towards these types of patients is insufficient or even non-existent. The most important part in the recovery of the interviewed is their own strength and motivation. All of these women today have new strategies on how to handle life's adversity and difficulties.</p>

L'analyse de la coordination autour des ressources communes s'est focalisée essentiellement sur la question du choix des instruments de gestion permettant d'orienter le comportement des agents économiques. Ce faisant le rôle potentiel des logiques d'acteurs en amont du processus de coordination est insuffisamment étudié, ce qui explique en partie l'échec de certains de ces instruments. Dès lors, l'objectif de notre recherche consiste en la construction d'une grille de lecture à même d'appréhender les déterminants amont de la coordination. Nous intégrons, dans cette perspective, l'effet potentiel des variables institutionnelles, technologiques et relatives aux dynamiques locales sur les stratégies adoptées par les acteurs. Dans la partie empirique de notre travail nous nous sommes concentrés sur le problème spécifique du partage de la ressource en eau entre les agriculteurs et les ostréiculteurs dans le bassin versant de la Charente. Sur la base d'analyses quantitatives et qualitatives, nous montrons notamment l'existence de blocages macro-institutionnels et cognitifs qui réduisent significativement l'ensemble des stratégies possibles et supposent le maintien des prélèvements en eau. Cependant, nos investigations nous permettent également de mettre en évidence le jeu complexe des interactions locales entre les agriculteurs et les ostréiculteurs, et la façon dont celui-ci vient contrarier ces tendances et atténuer en partie le problème de partage de la ressource.
