Cette thèse contribue à l’analyse du rôle des réseaux de relations sur le fonctionnement du marché du travail. Si les employeurs et les demandeurs d’emploi comptent fréquemment sur leurs contacts, la proportion d’emploi effectivement pourvus par le biais des réseaux de relations varie d’un espace géographique à un autre. Dans le premier chapitre, nous analysons, à partir d’un modèle d’appariement à la Pissarides (2000) avec réseaux de relations, l’influence potentielle du degré de spécialisation professionnelle de l’économie et de la diversité de l’origine immigrée des travailleurs dans la zone. Nous montrons que la hausse de la spécialisation influe positivement sur la circulation des offres d’emploi par bouche-à-oreille. Si l’origine est le seul critère qui influence la formation des liens, la hausse de la diversité de l’origine immigrée des travailleurs a par contre un impact négatif. Dans un second chapitre, nous réévaluons les résultats précédents dans un cadre théorique étendu : les travailleurs ont différents niveaux de qualification, certains sont déclassés et cherchent un meilleur emploi sur le tas. Nos résultats indiquent que la recherche sur le tas affecte négativement la distribution des offres d’emploi par bouche-à-oreille. Dans le troisième chapitre, nous montrons à partir des données de l’enquête Trajectoires et Origines de l’Ined/Insee (2008) que la hausse de la diversité de l’origine des travailleurs fluidifie la circulation des offres d’emploi par bouche-à-oreille. Toujours à partir des mêmes données,nous établissons, dans le quatrième chapitre, que les offres fournies par les contacts sont souvent peu appropriées aux compétences des travailleurs. / This work aims at contributing to analyze the role of word-of-mouth communication in the job matching process. If employers and job seekers are used to relying on their social relations, the percentage of jobs finally filled through socialnetworks varies between geographical areas. In the first chapter, we analyze, through a matching model of the labormarket à la Pissarides (2000) with social networks, the potential influence of the level of both professional concentration and ethnic diversity in the area. We find that the rise of professional concentration has a positive impact on the distribution of information through contacts. However, if ethnic origin is the single criterion influencing networks formation, it has a negative impact. In the second chapter, we re-evaluate the results of chapter one in an extended theoretical framework: workers have different level of qualification, some employed workers are overqualified and search on-the-job to improve their situation. Our results indicate that on-the-job search has a negative impact on the word-of-mouth communication process. In the third chapter, we show, from the French Trajectories and Origins survey from Ined/Insee (2008) that the rise of ethnic diversity has a positive impact on word-of-mouth communication in the labor market. Still from the same dataset, we find, in chapter four, that job offers provided by contacts are generally not appropriate to workers competences.

As mutações da sociedade atual e a aceleração do tempo histórico levam a um impulso de coesão com e no passado, de arraigo às origens, buscando pistas de identidade contidas nesse passado coletivo. Os fenômenos da globalização parecem conduzir a uma necessidade de enraizamento e de continuidade; necessidades preenchidas pela memória. Esta, na perspectiva de Maurice Halbwachs, possui ao mesmo tempo um caráter individual e um coletivo, sendo, em parte, modelada pela família e pelos grupos sociais. Revela tanto aspectos da identidade pessoal como social e aponta qual lugar os indivíduos e os grupos ocupam na sociedade. A tradição judaica é a tradição da memória por excelência e a história do povo judeu ilustra os mecanismos da memória e da lembrança. Nesta tradição os rituais e os relatos são canais que transmitem a memória através dos tempos. O objetivo desta pesquisa foi estudar como membros e familiares de uma comunidade judaica vivem a memória coletiva e o que isso significa em suas vidas cotidianas, visando apreender o processo de construção da identidade individual. Entrevistamos 13 pessoas, de cinco famílias diferentes, descendentes de judeus que imigraram para o Brasil. O contato foi proporcionado pela Sociedade Israelita de Ribeirão Preto. Para entrevistar, utilizamos o método da história oral, uma narrativa linear e individual do que os participantes consideram significativo. Neste método, a memória é uma forma de evidência histórica e deve ser analisada como tal. Considerando que na memória as pessoas constroem um sentido do passado, a reflexão ocupa um lugar fundamental para a ressignificação deste passado recordado. As entrevistas, gravadas e transcritas, são apresentadas na íntegra. Os participantes são categorizados em grupos, por família e grau de parentesco. Família 1: Maria (filha), Fernando (neto) e Calebe (neto); Família 2: Patrícia (filha) e Iracy (neta); Família 3 : Antônio (filho), Josy (neta) e Alex (neto); Família 4: Vânia (filha) e Talita (neta); Família 5: Zélia (filha), Daniel (neto) e Raquel (neta). Os nomes são fictícios visando preservar sua identidade. Nas entrevistas notamos uma riqueza pela diversidade e semelhança: são pessoas da mesma família ou de famílias diferentes, que percebem e elaboram a experiência de suas famílias de modos distintos, particulares, complementares e às vezes parecidos, que enriquece a análise e favorece a reflexão, servindo de modelo para alguns aspectos da vida. Também percebemos um processo de construção da identidade: necessidade de contar ou silenciar; como enfrentam eventos traumáticos; como preservam ou não a religião e as tradições; as mudanças ao longo das gerações; a relação com o trabalho e o meio em que vivem; os valores herdados e transmitidos para as próximas gerações, entre outros aspectos que surgiram nas narrativas. O conceito de memória coletiva iluminou a maneira de olharmos para os participantes e seus relatos. Possibilitou que notássemos o que ficou do passado no grupo estudado e o que o grupo fez com o passado. Mais do que conclusões ou pressupostos, alertamos que as entrevistas possuem infindáveis conteúdos para serem explorados e apenas alguns destes aspectos foram abordados neste estudo. / Changes in society and the current acceleration of historical time lead to a impulse and cohesion with the past, to root of the origins, seeking identity clues contained in this collective past. The phenomena of globalization seem to lead to a need for rootedness and continuity; these needs are filled by the memory. From the perspective of Maurice Halbwachs memory has both an individual and a collective character, being partly shaped by family and social groups. It reveals both aspects of personal and social identity and points which place individuals and groups occupied in society. The Jewish tradition is the tradition of memory by excellence and the Jewish people´s history illustrates the mechanisms of memory and remembrance. In this tradition rituals and accounts are channels that transmit memory through the ages. The aim of this research was to study how members and relatives from Jewish community live the collective memory and what it means in their everyday lives, in order to apprehend the process of individual identity construction. We interviewed 13 people from five different families, descendants of Jews who immigrated to Brazil. The contact was provided by the Israeli Society of Ribeirão Preto. To interview, we used the oral history method, a linear and individual narrative of what the participants considered significant. In this method, the memory is a way of historical evidence and should be considered as such. Considering that in memory people build a sense of the past, reflection occupies a key place to resignification this past remembered. The interviews were taped and transcribed, are presented in full. Participants are categorized in groups by family and parentage. Family 1: Maria (daughter), Fernando (grandson) and Calebe (grandson); Family 2: Patricia (daughter) and Iracy (granddaughter); Family 3: Antônio (son), Josy (granddaughter) and Alex (grandson); Family 4: Vânia (daughter) and Talita (granddaughter); Family 5: Zélia (daughter), Daniel (grandson) and Raquel (granddaughter). The names are fictitious to preserve their identity. In the interviews we noticed a wealth of diversity and similarity: they are people from the same family or different families, who realize and elaborate their families experience in different, particular, complementary and sometimes similar ways, which enriches the analysis and encourages reflection, serving as a model for some aspects of life. Also realize a process of identity construction: need for tell or silence; how they face traumatic events; how preserve or not religion and traditions; changes over the generations; the relationship with the work and the medium in which they live; values inherited and transmitted to the next generations, among other aspects that emerged in the narratives. The concept of collective memory illuminated the way we look into the participants and their accounts. Enabled us to observe what became from the past in the group studied and what the group made with the past. More than conclusions or assumptions, we caution that the interviews have countless content to be explored, and only some of these aspects were approached in this study.

Orientador: Débora Cristina Damasceno / Abstract: Maternal exposure to the high-fat diet (HFD) during gestation or lactation can be harmful to both mother and offspring. The objective of this systematic review was to synthesize the available data on the effects of maternal HFD on the reproductive parameter and biochemical profile in rodents. The electronic search was performed in the PUBMED (Public/Publisher MEDLINE), EMBASE (Ovid) and Web of Science databases. Data from 76 studies showed that change in biochemical and reproductive parameters is dependent on the experimental design. Furthermore, the heterogeneity found in the studies makes it impossible to comparisons. In addition, studies often omit or neglect important information, such as a description of the diet or methodological details. These factors make it difficult to affirm the true effect of maternal HFD consumption for both mother and offspring. / Resumo: A exposição materna à dieta hiperlipídica (DHL) durante a gestação ou lactação pode ser prejudicial tanto para a mãe quanto para seus descendentes. O objetivo desta revisão sistemática foi sintetizar os dados da literatura referente aos efeitos do consumo materno de DHL sobre os parâmetros reprodutivos e perfil bioquímico em roedores. A busca eletrônica foi realizada nos bancos de dados PUBMED (Public / Publisher MEDLINE), EMBASE (Ovid) e Web of Science. Dados de 76 estudos mostraram que a mudança nos parâmetros bioquímicos e reprodutivos é dependente do design experimental. A heterogeneidade encontrada nos estudos impossibilita as comparações. Além disso, os estudos frequentemente omitem ou negligenciam informações importantes, como a descrição da dieta ou detalhes metodológicos. Esses fatores dificultam a afirmação do verdadeiro efeito do consumo materno de DHL para a mãe e a prole. / Doutor

A tese O testemunho e suas formas: historiografia, literatura, documentário (Brasil, 1964-2017) tem por objetivo compreender as formas de expressão do testemunho da resistência à ditadura civil-militar brasileira e, especialmente, de descendentes imediatos da geração que enfrentou o autoritarismo. A pesquisa percorre a literatura elaborada em primeira pessoa e a filmografia que utiliza o testemunho como figura central ou coadjuvante. O panorama destaca os relatos em torno de trajetórias dos que se opuseram ao regime, os quais incluem os registros de filhas(os) acerca de suas lembranças ou do que lhes fora contado sobre as experiências de seus pais. No entendimento de que o cinema é um dos vetores da lembrança que compõe a memória pública sobre as ditaduras do Cone Sul, a análise proposta por essa pesquisa emerge dos filmes Diário de uma Busca (2010) e Os dias com ele (2013), roteirizados e dirigidos, respectivamente, pelas cineastas Flávia Castro e Maria Clara Escobar, filhas de atingidos pela repressão ditatorial. Os conteúdos abordados pelos longas-metragens trazem à luz questões de ordem teórica e metodológica em torno do testemunho articulado em documentários e as (im)possibilidades de retratar essas experiências. As análises serão orientadas pela tríade proposta por Michel de Certeau (1974) acerca da operação historiográfica, retomada por Paul Ricoeur (2000), nas suas reflexões sobre a epistemologia da história e por Sylvie Lindeperg (1996) em investigações sobre filmes, para os quais propõe uma operação cinematográfica. Na primeira parte, o enfoque está na configuração do testemunho para a historiografia após a Shoah e sua referência para os estudos dirigidos às ditaduras. Desse modo, proponho que no Brasil após o golpe de 1964, as declarações testemunhais foram originadas em diferentes condições, que caracterizo como voluntária, obrigada, convocada e induzida por um dever de justiça. Por fim, apresento o testemunho sobrevivente na literatura e no cinema desde o golpe civil-militar até 2017. Na segunda parte, centralizo as discussões nos filmes selecionados e abordo o percurso testemunhal provocado pelos protagonistas de Os dias com ele em que apontam o fragmentário retrato da tortura. Além disso, identifico as tensões entre as narrativas testemunhais em Diário de uma busca e o itinerário sobre as lacunas que permeiam a trama. No intuito de desenvolver as problemáticas elencadas, foram cotejados, além dos filmes selecionados, entrevistas cedidas pelas cineastas à autora desta tese, notícias e reportagens veiculadas pela imprensa, documentos elaborados pelos órgãos de repressão da ditadura civil-militar brasileira, relatórios ou acervos dos projetos estatais de memória e reparação. Destaco que a conjunção de lembranças que conferem forma ao testemunho sobrevivente, aportada nas narrativas originadas em condições voluntárias, permite a circularidade da experiência individual, bem como de suas marcas subjetivas, para o vivido partilhado socialmente.O tema familiar que reside, invariavelmente, na perspectiva filial irrompe nas imagens dos documentários, os quais propõem uma quebra dos silêncios históricos, pessoais e infinitos para si e para o país. Assim, os testemunhos dos descendentes daquela oposição ao inscreverem seus enfrentamentos em favor do inaudito contribuem, igualmente, para uma forma de representação da história. / The thesis The testimony and its forms: historiography, literature, documentary (Brazil, 1964-2017) aims at understating the shape that testimonies regarding the resistance to the Brazilian civil military dictatorship took, and, especially, those of the direct descendants of the generation who fought authoritarianism. This research goes through literary discourses narrated in the first person and the filmography that focuses on testimony as a central or tangential aspect of the narrative. The overview of this analysis highlights reports on the trajectories of those who opposed the dictatorial regime, including records of daughters and sons sharing their memories of stories about their parents’ experience. Provided that cinema is one of the vectors of remembrance that constitutes public memory on dictatorship regimes of the Southern Cone, the proposed analysis in this research stems from the films Diário de uma Busca (“Diary, Letters, Revolutions”) from 2010 and Os dias com ele (“The Days With Him”) from 2013, written and directed by filmmakers Flávia Castro and Maria Clara Escobar, respectively. Both are daughters of people who suffered dictatorial repression. The content of both feature films brings light to questions of theoretical and methodological nature, when it comes to testimony articulated into documentary form and the (in)possibilities to portray such experiences. These analyses are oriented by the triad proposed by Michel de Certeau (1974) on the historiographical operation, took up by Paul Ricoeur (2000), on his reflections about epistemology of History, and by Sylvie Lindeperg (1996) in her investigations about movies, in which she proposes a cinematic operation. First, the focus is on the configuration of testimony to the historiography after Shoah and its centrality to the studies about dictatorships. Along these lines, my proposition is that, in Brazil after the military coup of 1964, the testimonial declarations arose from different conditions, ones that I characterize as voluntary, obligated, summoned and induced by a duty of justice. Lastly, I present the survival testimony in literature and cinema since the civil military coup until 2017. Secondly, I condense the debate on the selected films, and approach the fragmented portrayal of torture pointed out by the path of testimony raised by the protagonists of Os dias com ele. Furthermore, I identify the tensions between testimonial narratives and the itinerary of the gaps that permeate the plot in Diário de uma busca. Having in mind the goal to explore all the former problems, I analyzed, besides the selected films, interviews I conducted with the filmmakers, media news and reports, documents produced by official repression enforcement offices and reports or archives of State projects on memory and atonement. I highlight that the combination of memories that shape the survival testimony produced in the narratives, originated in voluntary conditions, allows a circularity of individual experiences - and their subjective traces - to the socially shared living experiences. The familiar topic that invariably resides in the narrative perspective of the direct descendants comes to light in the images of the documentaries, and proposes a crack in historical silences, personal and infinite both individually and for the country. Therefore, the testimony of daughters and sons of the generation who opposed the regime also contribute, by inscribing themselves into the unprecedented, with a way of historical representation.

In Africa, this infection is highly endemic, with the majority of individuals becoming infected during childhood. Although Brazil has been globally considered a country of HBV intermediate endemicity, variable rates have been found in all five Brazilian regions and even inside the same region. This study aimed to investigate the epidemiological and molecular profile of the HBV infection among the Kalunga population in Goiás, Central Brazil, which is considered the largest Afro-Brazilian isolated community. A total of 878 individuals were interviewed about sociodemographic characteristics, risk factors and HBV vaccination. Blood samples were collected from all participants and serum samples were screened by enzyme-linked immunosorbent assay for the presence of HBsAg, anti-HBc and anti-HBs serological markers. HBsAg-positive samples were submitted to HBeAg and anti-HBe detection. HBsAg and anti-HBc positive samples were tested for HBV DNA detection by polymerase chain reaction and genotyping by subsequent restriction fragment length polymorphism (RFLP) analysis and nucleotide sequencing of preS/S region. The overall prevalence of HBV infection was 35.4% (95% CI: 32.3-38.7). HBsAg carrier rate was 1.8% (95% CI: 1.1- 3.0). Multivariate analysis of risk factors showed that increased age, male gender, illiteracy and history of multiple sexual partners were associated with this infection. Isolated anti-HBs was found in 301 (34.3%) individuals who were immune for hepatitis B. HBV DNA was detected in 75% (12/16) of the HBsAg positive samples, in 100% (2/2) of the HBeAg and in 83.3% (10/12) of the anti-HBe positive samples. An occult HBV infection rate of 1.7% (5/295) was found among anti-HBc positive individuals. All genotyped isolates belonged to genotype A by RFLP analysis. Nucleotide sequencing of preS/S region confirmed the circulation of genotype A (subgenotype Aa) in this community. The epidemiological findings indicate that preventive measures, such as additional health education and HBV vaccination programs, are needed to control HBV infection in this population. In addition, the molecular results suggest the introduction of genotype A, subgenotype Aa in Brazil from Africa during the slave trade. / infecção pelo vírus da hepatite B (HBV) apresenta distribuição mundial. Na África, é altamente endêmica, sendo a maioria dos indivíduos infectada durante a infância. Embora o Brasil seja considerado um país de endemicidade intermediária, taxas variadas de prevalência têm sido encontradas nas cinco regiões geográficas e mesmo dentro de uma mesma região. Este estudo teve como objetivo investigar o perfil epidemiológico e molecular da infecção pelo HBV na população Kalunga em Goiás, Brasil Central, que é considerada a maior comunidade afro-descendente isolada no Brasil. Um total de 878 indivíduos foi entrevistado sobre características sócio-demográficas, fatores de risco e vacinação contra hepatite B. Amostras sanguíneas foram coletadas de todos os participantes e os soros triados para detecção dos marcadores HBsAg, anti-HBc total e anti-HBs por ensaio imunoenzimático. As amostras HBsAg positivas foram submetidos à detecção dos marcadores HBeAg e anti-HBe. O DNA viral foi detectado nas amostras HBsAg e anti-HBc reagentes pela reação da polimerase em cadeia, sendo as amostras HBV DNA positivas genotipadas pela análise do polimorfismo de comprimento dos fragmentos de restrição (RFLP) e sequenciamento da região Pré-S/S. A prevalência global da infecção pelo HBV foi de 35,4% (IC 95% 32,3-38,7), sendo de 1,8% (IC 95% 1,1-3,0) para o HBsAg. A análise multivariada mostrou que aumento da idade, gênero masculino, analfabetismo e história de múltiplos parceiros sexuais foram fatores associados a esta infecção. Em 301 (34,3%) indivíduos, verificou-se positividade isolada ao marcador anti-HBs, sugerindo imunidade ao HBV. O HBV DNA foi detectado em 75% (12/16) das amostras HBsAg reagentes, em 100% (2/2) das HBeAg e 83,3% (10/12) das anti-HBe positivas. Um índice de 1,7% (5/295) para infecção oculta pelo HBV foi encontrado nos indivíduos anti-HBc reagentes. Todas as amostras genotipadas por RFLP foram do genótipo A. O sequenciamento da região Pré-S/S confirmou a circulação do genótipo A (subgenótipo Aa) nesta comunidade. Os achados epidemiológicos indicam que medidas preventivas, como programas de educação em saúde e de vacinação contra hepatite B, são necessárias para o controle da infecção pelo HBV nesta população. Além disso, os resultados moleculares sugerem que o genótipo A, subgenótipo Aa foi introduzido no Brasil durante o tráfico de escravos da África.

A little over 20 years ago Drinfeld presented the quantum (or Drinfeld) double construction. This construction takes any Hopf algebra and embeds it in a larger quasi-triangular Hopf algebra, which contains an algebraic solution to the constant Yang–Baxter equation. One such class of algebras consists of the Drinfeld doubles of finite groups, which are currently of interest due to their connections with non-Abelian anyons. The smallest non-commutative Drinfeld double of a finite group algebra is the Drinfeld double of D3 , the dihedral group of order six, which was recently used to construct solutions to the Yang–Baxter equation cor- responding to 2-state and 3-state integrable spin chains with periodic boundary conditions. In this thesis we construct R-matrices from the Drinfeld double of dihedral group algebras, D(Dn) and consider their associated integrable systems. The 3-state spin chain from D(D3) is generalised to include open boundaries and it is also shown that there exists a more general R-matrix for this algebra. For general D(Dn) an R-matrix is constructed as a descendant of the zero-field six-vertex model.

Cette thèse propose une analyse empirique et comparative des conditions d’emploi des descendants d’immigrés en France et aux États-Unis. L’objectif est de mieux caractériser l’intégration sur le marché du travail des descendants d’immigrés, en adoptant une approche multidimensionnelle. La comparaison entre la France et les États-Unis permet de mettre en lumière les dimensions sur lesquelles portent les inégalités en termes de conditions d’emploi entre les descendants d’immigrés et de natifs dans chacun des pays, afin de mieux spécifier ces inégalités. Notre analyse explore dans un premier chapitre, le déclassement professionnel, dans un deuxième chapitre, trois aspects de la sécurité socio-économique de la qualité de l’emploi et enfin, dans un dernier chapitre, la distribution des écarts de salaire. Bien que des écarts en termes de conditions d’emploi existent dans les deux pays en défaveur des descendants d’immigrés, ces écarts ne semblent pas être le résultat d’inégalités mais plutôt d’effets de structure, telles que les différences d’âge ou de niveau d’éducation entre les deux groupes. Les professions et secteurs d’activité dans lesquels les descendants d’immigrés travaillent expliquent aussi ces écarts. Les résultats montrent des similarités entre les deux pays : une fois le biais de sélection à l’accès à l’emploi pris en compte, le fait d’avoir des parents immigrés n’a pas d’effet significatif sur le déclassement professionnel (chapitre 1) mais un effet positif et significatif sur le salaire (chapitre 2). En revanche, les deux pays se distinguent sur plusieurs points. En France, être descendant d’immigrés contribue à significativement freiner l’accès à l’emploi et à diminuer la sécurité de l’emploi. En revanche, aux États-Unis cela a un effet négatif uniquement sur le temps de travail (chapitre 2). Cette thèse défend la prise en compte de l’hétérogénéité qui existe au sein de la population des descendants d’immigrés en termes de pays d’origine de leurs parents. En effet, des effets contradictoires selon le pays d’origine des parents peuvent conduire à des effets non significatifs au niveau agrégé, comme c’est le cas pour le déclassement par exemple. Le dernier chapitre montre un écart salarial plus marqué pour les bas salaires dans les deux pays, avec toutefois comme différence majeure que ce qui reste inobservable contribue à diminuer l’écart salarial entre descendants de natifs et d’immigrés aux États-Unis mais à l’augmenter en France. / The comparison between France and the United States shows how the inequalities in terms of employment conditions between descendants of immigrants and of native-born persons differ.This thesis proposes an empirical and comparative analysis of the employment conditions of immigrants’ offspring in France and in the United States. The goal is to better characterise the labour market integration of immigrants’ offspring, taking a multidimensional approach. The comparison between France and the United States highlight the dimensions of inequalities in terms of employment conditions between the descendants of immigrants and of native-born in each of country, henceforth improving the characterisation of these inequalities. Our analysis explores overeducation in a first chapter, in a second chapter, three aspects of the socio-economic security of job quality and in a final chapter, the distribution of wage differentials. Although differences in terms of employment conditions exist in both countries to the detriment of immigrants’ offspring, these differences do not appear to be the result of inequalities but rather of structural effects such as differences in age or education level between the two groups. The occupations and sectors of activity in which descendants of immigrants work also explain these differences. The results show similarities between the two countries. Once the selection bias to access employment is taken into account, having immigrant parents has no significant effect on overeducation (chapter 1) but a positive and significant effect on wages (chapter 2). On the other hand, the two countries differ on several points. In France, having immigrant parents significantly restricts the access to employment and lowers job security. However, in the United States, there is a negative effect only on working time (chapter 2). This thesis advocates for the consideration of the heterogeneity that exists within the population immigrants’ offspring, according to their parents’country of origin. Indeed, contradictory effects according to the parents’ country of origin may lead to non-significant effects at the aggregate level, as is the case for overeducation, for example. The final chapter shows a wider wage gap for low-wage workers in the two countries. Nevertheless, the major difference between the two countries is that the unobservable component contributes to narrowing the wage gap between natives and of immigrants but to increasing it in France.
