Classificação étnico-racial e ações afirmativas no contexto do vestibular

Os conceitos de raça e etnia são basilares para a antropologia desde o seu surgimento como área do conhecimento humano e, ainda hoje, são fundamentais para diversos debates nas esferas política, social e das ciências humanas em geral. No pensamento social brasileiro muitos foram os autores de diversas áreas a se debruçarem sobre a questão racial. A instituição do sistema de cotas para o ingresso em universidades acalorou e expandiu o debate tanto no senso comum como na academia e nos meios de comunicação em geral. Essa pesquisa partiu da intenção de investigar a relação entre as ações afirmativas e as identidades de cor/raça. Como metodologia, utilizamos os recursos tanto dos instrumentos quantitativos como qualitativos. Nosso foco foram estudantes do cursinho pré-vestibular Grupo Perspectiva Integral (GPI). Buscamos acessar o ponto de vista dos vestibulandos, seus significados e associações acerca de suas identidades étnico-raciais, opiniões e sentimentos sobre a questão racial no Brasil e, em especial referente às ações afirmativas no contexto da educação e investigar a relação entre quem sou eu e qual é a minha cor/raça no universo proposto. Para tanto, foram aplicados cento e vinte e um questionários e realizadas doze entrevistas. A intenção não era estabelecer uma relação direta e causal entre as ações afirmativas e as identidades de cor/raça e, sim, traçar um perfil geral e racial da população estudada, perceber e analisar diversos elementos referentes às classificações de cor/raça e opiniões e sentimentos acerca das ações afirmativas, do racismo e das expectativas profissionais dos vestibulandos.

Tão longe, tão perto: pretos e pardos e o enigma racial brasileiro

Até meados da década de 1970 buscou-se decifrar o lugar social ocupado pelo pardo na sociedade brasileira. Contudo, os estudos mais recentes se caracterizaram, com algumas exceções, pelo silenciamento em torno das especificidades desse grupo. Pretos e pardos têm sido agrupados em uma mesma categoria para fins de análise de desigualdades e discriminação racial. No entanto, se os pardos estão extremamente próximos dos pretos no que toca os seus índices socioeconômicos, chances de mobilidade social e vitimização pela discriminação, eles estão muito distantes dos pretos em sua percepção do preconceito e da discriminação de que são vítimas. Para esse grupo, o nexo entre a cor e a discriminação não parece nem um pouco evidente. A presente tese retoma os pardos como tema de reflexão e investiga as razões pelas quais eles parecem ser discriminados em intensidade próxima à dos pretos, mas não reportam a discriminação no mesmo grau. A partir da produção de análises originais de dados quantitativos e surveys sobre racismo, encontro respaldo para algumas explicações não mutuamente excludentes para esse fenômeno: (1) o binarismo das linguagens racista e antirracista no Brasil, que exclui os pardos do debate público, (2) os problemas metodológicos dos surveys sobre discriminação racial, (3) a presença ideário da morenidade na identidade e autoimagem dos brasileiros pardos, (4) as peculiaridades da sociabilidade entre pretos, pardos e brancos, (5) o caráter ambivalente dos estereótipos que incidem sobre os pardos e, finalmente, (6) uma porosidade maior das elites brancas em relação a esses indivíduos. A partir da elaboração de um modelo alternativo de mensuração da percepção da discriminação, baseado na Escala de Discriminação Cotidiana, demonstro que pretos e pardos de classes mais baixas têm percepções mais parecidas de atitudes discriminatórias, enquanto aqueles que atingem as classes médias e elites passam a divergir: os pretos passam a reportar mais intensamente a discriminação, enquanto os pardos praticamente cessam de senti-la. Sustento que o racismo ambivalente brasileiro funciona de modo a barrar a mobilidade social tanto de pretos como de pardos, mas que os estereótipos e atitudes a que ele está relacionado penalizam mais severamente os pretos que ascendem socialmente do que os pardos.

Shore Shapers: Introducing children and the general public to biogeomorphological processes and geodiversity

Coastal processes and wildlife shape the coast into a variety of eye-catching and enticing landforms that attract people to marvel at, relax and enjoy coastal geomorphology. These landforms also influence biological communities by providing habitat and refuge. There are very few field guides to explain these processes to the general public and children. In contrast, there is a relative wealth of resources and organised activities introducing people to coastal wildlife, especially on rocky shores. These biological resources typically focus on the biology and climatic controls on their distribution, rather than how the biology interacts with its physical habitat. As an outcome of two recent rock coast biogeomorphology projects (detailed at: www.biogeomorph.org/coastal) a multi disciplinary team produced the first known guide to understanding how biogeomorphological processes help create coastal landforms. The ‘Shore Shapers’ guide (shoreshapers.org) is designed to: a. bring biotic geomorphic interactions (how animals, algae and microorganisms protect and shape rock) to life and b. introduce some of the geomorphological and geological controls on biogeomorphic processes and landform development. The guide provides scientific information in an accessible and interactive way – to help sustain children’s interest and extend their learning. We tested a draft version of the guide with children,the general public and volunteers on rocky shore rambles using social science techniques and present the findings, alongside initial results of an evaluation of a newer version of the guide and interactive workshops taking place throughout 2014.

Love Thy Neighbor? Relationships between Religion and Racial Intolerance in Europe.

This article examines relationships between religion and racial intolerance across 47 countries by applying multilevel modeling to European survey data and is the first in-depth analysis of moderation of these relationships by European national contexts. The analysis distinguishes a believing, belonging, and practice-dimension of religiosity. The results yield little evidence of a link between denominational belonging, religious practice, and racial intolerance. The religiosity dimension that matters most for racial intolerance in Europe is believing: believers in a traditional God and believers in a Spirit/Life Force are decidedly less likely, and fundamentalists are more likely than non- believers to be racially intolerant. National contexts also matter greatly: individuals living in Europe’s most religious countries, countries with legacies of ethnic-religious conflict and countries with low GDP are significantly more likely to be racially intolerant than those living in wealthier, secular and politically stable countries. This is especially the case for the religiously devout.

Rapport au travail, mobilité professionnelle et parcours de vie : le cas de jeunes infirmières et infirmières auxiliaires d'un centre de santé et de services sociaux

Cette thèse de doctorat, qui s’inscrit dans un programme de doctorat en sciences humaines appliquées, s’est d’abord construite en réponse à un problème concret, celui du roulement des infirmières et des infirmières auxiliaires dans le réseau de la santé et des services sociaux. En cours de route, il est toutefois apparu nécessaire d’élargir le questionnement à la question du rapport au travail des jeunes infirmières pour être en mesure de saisir les dynamiques sociales plus larges qui conditionnent certains choix professionnels, dont la décision de quitter son emploi. Cette thèse poursuit donc deux grands objectifs. D’une part, elle s’attarde à cerner l’ensemble des processus qui conduisent les jeunes infirmières à faire le choix de quitter leur emploi. D’autre part, elle vise à mieux comprendre comment a évolué leur rapport au travail dans le temps. La perspective théorique retenue s’appuie sur deux approches complémentaires, soit celles de la perspective des parcours de vie et de divers courants en sociologie de l’individu qui ont comme point commun d’accorder une place importante au contexte social, aux contraintes structurelles, de même qu’à l’autonomie des acteurs et à leur capacité d’agir sur leur parcours de vie. Ces approches s’avèrent particulièrement pertinentes dans le cadre de notre étude puisqu’elles permettent de rendre compte des liens complexes entre le contexte social plus global, les différents contextes de vie d’un individu et ses comportements en emploi. Elles invitent à conceptualiser le rapport au travail comme un processus qui évolue dans le temps à travers lequel plusieurs éléments de la vie d’un individu et de ses proches se combinent pour donner une orientation particulière aux trajectoires professionnelles. Vu sous cet angle, la décision de quitter se présente également comme un processus qui se construit dans un laps de temps plus ou moins long où entrent en jeu plusieurs dimensions de la vie d’un individu. La perspective adoptée dans le cadre de cette thèse permet de combler des lacunes dans ce champ de recherche où peu d’études se sont attardées à comprendre les différents processus qui façonnent le rapport au travail dans le temps et qui conduisent les infirmières à la décision de quitter leur emploi. Pour répondre aux objectifs de recherche, une étude qualitative a été menée. Des entrevues individuelles de type récit de vie ont été effectuées pour comprendre, du point de vue des participantes, comment a évolué leur rapport au travail et les processus qui les ont amenées à quitter leur emploi. Une étude de cas a été effectuée dans un centre de santé et de services sociaux de la province de Québec qui affichait un taux de roulement particulièrement élevé. L’étude visait les infirmières et les infirmières auxiliaires, groupe professionnel fortement touché par le roulement de la main-d’œuvre. Des entretiens en profondeur, d’une durée de 2h30 à 3 heures, ont été réalisées auprès de 42 infirmières et infirmières auxiliaires. Les résultats de la recherche sont présentés à travers la production de trois articles scientifiques. Le premier article, Pour une compréhension dynamique du rapport au travail: la valeur heuristique de la perspective des parcours de vie, a pour objectif de faire ressortir l’intérêt que présentent les principes analytiques associés à cette perspective dans l’étude du rapport au travail. Dans cet article, nous démontrons que le rapport au travail est le résultat d’un processus complexe où les aspirations des individus, leurs conditions concrètes d’emploi et les événements qui surviennent dans leur vie personnelle et familiale entretiennent des liens dynamiques et interdépendants qui façonnent le rapport au travail tout au long de la vie. Cet article apporte des éléments de réflexion à la question posée par plusieurs chercheurs : par quel moyen saisir ce qu’il en est du rapport au travail des jeunes? Le deuxième article, Rencontre entre l’idéaltype de travailleur et l’idéal de travail : le cas de jeunes infirmières en début de vie professionnelle, vise à rendre compte de la manière dont s’est faite la rencontre entre les attentes que les infirmières nourrissent à l’égard du travail et leur réalité concrète de travail à une période précise de leur trajectoire professionnelle, soit celle de leur insertion en emploi et des premières années de pratique. L’article démontre que trois dimensions du rapport au travail sont affectées par les nouvelles normes managériales qui prévalent dans le réseau de la santé et des services sociaux : 1) la place souhaitée du travail dans la vie, 2) la réalisation de soi par le travail et 3) le sens au travail. Cet article apporte une contribution dans la compréhension du rapport au travail de jeunes professionnelles qui exercent un métier de relation d’aide dans le contexte spécifique du réseau québécois de la santé et des services sociaux. Le troisième article, Comprendre le roulement comme un processus lié au cycle de la vie : le cas des infirmières, traite plus spécifiquement de la question du roulement de la main d’œuvre infirmière. Quatre parcours de départs sont présentés qui possèdent des caractéristiques distinctes relatives à la rencontre entre les attentes et la réalité concrète de travail, l’interaction entre le travail et la vie hors travail et la manière dont s’est construite dans le temps la décision de quitter son emploi. Les résultats démontrent que la décision de quitter se présente comme un processus qui se construit dans un laps de temps plus ou moins long, qui implique différentes dimensions de la vie d’un individu et qui est intimement lié à la quête de réalisation de soi au travail et dans les autres domaines de la vie. Cet article propose une façon d’appréhender le phénomène du roulement qui se distingue des modèles dominants qui abordent cette question à partir d’une lecture essentiellement individualisante et psychologisante des départs. La contribution de cette thèse à l’avancement des connaissances réside principalement dans le fait qu’elle appréhende autrement la question du rapport au travail et celle du roulement de la main-d’œuvre en recourant à la perspective des parcours de vie et à la sociologie de l’individu. L’approche que nous avons préconisée permet de saisir les processus sociaux et la multiplicité des éléments à prendre en considération dans l’étude du rapport au travail des jeunes infirmières et de la décision de quitter son emploi. Elle met en exergue l’importance de considérer le contexte social plus global dans lequel s’inscrit tout individu qui, dans les sociétés contemporaines, doit s’engager dans un travail de construction identitaire tout au long de la vie.

Decision‐Making in Public Good Dilemmas: Theory and Agent‐Based Simulation

In many real world contexts individuals find themselves in situations where they have to decide between options of behaviour that serve a collective purpose or behaviours which satisfy one’s private interests, ignoring the collective. In some cases the underlying social dilemma (Dawes, 1980) is solved and we observe collective action (Olson, 1965). In others social mobilisation is unsuccessful. The central topic of social dilemma research is the identification and understanding of mechanisms which yield to the observed cooperation and therefore resolve the social dilemma. It is the purpose of this thesis to contribute this research field for the case of public good dilemmas. To do so, existing work that is relevant to this problem domain is reviewed and a set of mandatory requirements is derived which guide theory and method development of the thesis. In particular, the thesis focusses on dynamic processes of social mobilisation which can foster or inhibit collective action. The basic understanding is that success or failure of the required process of social mobilisation is determined by heterogeneous individual preferences of the members of a providing group, the social structure in which the acting individuals are contained, and the embedding of the individuals in economic, political, biophysical, or other external contexts. To account for these aspects and for the involved dynamics the methodical approach of the thesis is computer simulation, in particular agent-based modelling and simulation of social systems. Particularly conductive are agent models which ground the simulation of human behaviour in suitable psychological theories of action. The thesis develops the action theory HAPPenInGS (Heterogeneous Agents Providing Public Goods) and demonstrates its embedding into different agent-based simulations. The thesis substantiates the particular added value of the methodical approach: Starting out from a theory of individual behaviour, in simulations the emergence of collective patterns of behaviour becomes observable. In addition, the underlying collective dynamics may be scrutinised and assessed by scenario analysis. The results of such experiments reveal insights on processes of social mobilisation which go beyond classical empirical approaches and yield policy recommendations on promising intervention measures in particular.

Perspectivas del debate en torno al concepto de europeidad al interior de la Unión Europea a la luz de los criterios de adhesión de Copenhague

Cuando se habla de los límites y fronteras de Europa, actualmente no están definidos en su totalidad, resultando problemático en la subregión del este, donde se encuentran Estados como Ucrania, Bielorrusia, Turquía y otros más. La delgada línea que divide a Europa de Asia aún es confusa, por lo cual delimitar el concepto de europeidad implica contemplar más variables que lo geográfico y cultural. De esta manera, la incertidumbre que existe está relacionada con los atributos que tiene la europeidad, y como los ciudadanos se identifican con ella. La europeidad antes que un conjunto de valores atribuible a los ciudadanos o una herencia cultural común, es un concepto difuso, efímero y esquivo para algunos autores. La trascendencia de este concepto se hace manifiesta en el artículo 49 del Tratado de la Unión Europea donde se estipulan las condiciones para ser miembro de la Unión Europea (UE). Aunque ser miembro de la UE no es lo mismo que ser europeo hasta este momento es la forma más aceptable para denominar a un Estado como europeo.

New insights into probiotic mechanisms: a harvest from functional and metagenomic studies

There has been continued and expanding recognition of probiotic approaches for treating gastrointestinal and systemic disease, as well as increased acceptance of probiotic therapies by both the public and the medical community. A parallel development has been the increasing recognition of the diverse roles that the normal gut microbiota plays in the normal biology of the host. This advance has in turn has been fed by implementation of novel investigative technologies and conceptual paradigms focused on understanding the fundamental role of the microbiota and indeed all commensal bacteria, on known and previously unsuspected aspects of host physiology in health and disease. This review discusses current advances in the study of the host-microbiota interaction, especially as it relates to potential mechanisms of probiotics. It is hoped these new approaches will allow more rational selection and validation of probiotic usage in a variety of clinical conditions.

Structural and Functional Studies of a Bothropic Myotoxin Complexed to Rosmarinic Acid: New Insights into Lys49-PLA(2) Inhibition

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)

Time-kill and synergism studies of ceftobiprole against Enterococcus faecalis, including beta-lactamase-producing and vancomycin-resistant isolates.

Ceftobiprole (BAL9141) is an investigational cephalosporin with broad in vitro activity against gram-positive cocci, including enterococci. Ceftobiprole MICs were determined for 93 isolates of Enterococcus faecalis (including 16 beta-lactamase [Bla] producers and 17 vancomycin-resistant isolates) by an agar dilution method following the Clinical and Laboratory Standards Institute recommendations. Ceftobiprole MICs were also determined with a high inoculum concentration (10(7) CFU/ml) for a subset of five Bla producers belonging to different previously characterized clones by a broth dilution method. Time-kill and synergism studies (with either streptomycin or gentamicin) were performed with two beta-lactamase-producing isolates (TX0630 and TX5070) and two vancomycin-resistant isolates (TX2484 [VanB] and TX2784 [VanA]). The MICs of ceftobiprole for 50 and 90% of the isolates tested were 0.25 and 1 microg/ml, respectively. All Bla producers and vancomycin-resistant isolates were inhibited by concentrations of

The Political Candidacy of EU Migrants in their European Countries of Residence. The Case of British and Romanians Standing in Spanish Local Elections

What explains the variation in how European citizens of diverse origins are politically incorporated in the member states of residence? This paper argues that immigrant groups’ status in the host society plays an important role in political party responses to immigrants’ political participation. Drawing on the case of Romanian and British candidacies in the Spanish local elections from 2011, the paper finds that the level of competition between parties is the key mechanism for incorporating candidates from a positively/neutrally perceived group. Instead, a greater level of ethnic diversity encourages the incorporation of candidates from the negatively perceived group. To demonstrate this, the paper uses an original data-set with the Romanian and British candidates in a large number of Spanish localities.

Sibling relationships in the family of a child with a burn injury

Purpose. Understanding siblings' experiences after a major childhood burn injury was the purpose of this mixed method, qualitative dominant study. The following research questions guided this project: How do siblings describe the impact of a major childhood burn injury experience? How do sibling relationship factors of warmth/closeness, relative status/power, conflict, and rivalry further clarify their relationship and their experience after a major burn injury? ^ Methods. A mixed method, qualitative dominant, design was implemented to understand the sibling experiences in a family with a child suffering from a major burn injury. Informants were selected from patients with childhood burn injuries attending the reconstructive clinic at a Gulf coast children's specialty hospital. The qualitative portion used the life story method, a narrative process, to portray the long-term impact on sibling relationships. A "case" represents a family unit and could be composed of one or multiple family members. Participants from 22 cases (N = 40 participants) were interviewed. Interviews were conducted in person and via telephone. The quantitative portion, or the embedded part of this mixed method design, used the Sibling Relationship Questionnaire Revised (SRQ-R) to conduct an additional structured interview and acquire scoring data. It was postulated that the SRQ-R would provide another perspective on the sibling experience and expand the qualitative data analysis. Thematic analysis was implemented on the qualitative interview data including the qualitative data from the interviews structured on the SRQ-R. Additionally, scores on the SRQ-R were tabulated to further describe the cases. ^ Results. The overall thematic pattern for the sibling relationship in families having a child with a major burn injury was that of normalization. Areas of normalization as well as the process of adjustment were the major themes. Areas of normalization were found in play and other activities, in school and work, and in family relations with their siblings and their parents. The process of adjustment in the sibling relationship was described as varied, involved school and work re-entry, and might even change their life perspective. Further analysis included an examination of the cases in which more than one person were interviewed and completed the SRQ-R. Participants from five ( n = 11) of six cases (n = 14), scored above 3.0 on the five-point scale on the Warmth/Closeness construct, indicating they perceived the sibling relationship as close. Five participants scored high on the Conflict construct and four participants scored high on the Rivalry construct. Finally, Relative Status/Power was low or negative in the six cases (n = 13). ^ Conclusions/implications. These findings suggest the importance of returning to normalcy for many of the families and the significance of sibling relationships on the process. Some of these families were able to use this major life event in a positive way to promote normalization. ^

A hybrid method in combining treatment effects from matched and unmatched studies

In the biomedical studies, the general data structures have been the matched (paired) and unmatched designs. Recently, many researchers are interested in Meta-Analysis to obtain a better understanding from several clinical data of a medical treatment. The hybrid design, which is combined two data structures, may create the fundamental question for statistical methods and the challenges for statistical inferences. The applied methods are depending on the underlying distribution. If the outcomes are normally distributed, we would use the classic paired and two independent sample T-tests on the matched and unmatched cases. If not, we can apply Wilcoxon signed rank and rank sum test on each case. ^ To assess an overall treatment effect on a hybrid design, we can apply the inverse variance weight method used in Meta-Analysis. On the nonparametric case, we can use a test statistic which is combined on two Wilcoxon test statistics. However, these two test statistics are not in same scale. We propose the Hybrid Test Statistic based on the Hodges-Lehmann estimates of the treatment effects, which are medians in the same scale.^ To compare the proposed method, we use the classic meta-analysis T-test statistic on the combined the estimates of the treatment effects from two T-test statistics. Theoretically, the efficiency of two unbiased estimators of a parameter is the ratio of their variances. With the concept of Asymptotic Relative Efficiency (ARE) developed by Pitman, we show ARE of the hybrid test statistic relative to classic meta-analysis T-test statistic using the Hodges-Lemann estimators associated with two test statistics.^ From several simulation studies, we calculate the empirical type I error rate and power of the test statistics. The proposed statistic would provide effective tool to evaluate and understand the treatment effect in various public health studies as well as clinical trials.^
