Decreased pyramidal neuron size in Brodmann areas 44 and 45 in patients with autism.

Autism is a neurodevelopmental disorder characterized by deficits in social interaction and social communication, as well as by the presence of repetitive and stereotyped behaviors and interests. Brodmann areas 44 and 45 in the inferior frontal cortex, which are involved in language processing, imitation function, and sociality processing networks, have been implicated in this complex disorder. Using a stereologic approach, this study aims to explore the presence of neuropathological differences in areas 44 and 45 in patients with autism compared to age- and hemisphere-matched controls. Based on previous evidence in the fusiform gyrus, we expected to find a decrease in the number and size of pyramidal neurons as well as an increase in volume of layers III, V, and VI in patients with autism. We observed significantly smaller pyramidal neurons in patients with autism compared to controls, although there was no difference in pyramidal neuron numbers or layer volumes. The reduced pyramidal neuron size suggests that a certain degree of dysfunction of areas 44 and 45 plays a role in the pathology of autism. Our results also support previous studies that have shown specific cellular neuropathology in autism with regionally specific reduction in neuron size, and provide further evidence for the possible involvement of the mirror neuron system, as well as impairment of neuronal networks relevant to communication and social behaviors, in this disorder.

On the evolution of harming and recognition in finite panmictic and infinite structured populations.

Natural selection may favor two very different types of social behaviors that have costs in vital rates (fecundity and/or survival) to the actor: helping behaviors, which increase the vital rates of recipients, and harming behaviors, which reduce the vital rates of recipients. Although social evolutionary theory has mainly dealt with helping behaviors, competition for limited resources creates ecological conditions in which an actor may benefit from expressing behaviors that reduce the vital rates of neighbors. This may occur if the reduction in vital rates decreases the intensity of competition experienced by the actor or that experienced by its offspring. Here, we explore the joint evolution of neutral recognition markers and marker-based costly conditional harming whereby actors express harming, conditional on actor and recipient bearing different conspicuous markers. We do so for two complementary demographic scenarios: finite panmictic and infinite structured populations. We find that marker-based conditional harming can evolve under a large range of recombination rates and group sizes under both finite panmictic and infinite structured populations. A direct comparison with results for the evolution of marker-based conditional helping reveals that, if everything else is equal, marker-based conditional harming is often more likely to evolve than marker-based conditional helping.

Deontological and altruistic guilt: evidence for distinct neurobiological substrates.

The feeling of guilt is a complex mental state underlying several human behaviors in both private and social life. From a psychological and evolutionary viewpoint, guilt is an emotional and cognitive function, characterized by prosocial sentiments, entailing specific moral believes, which can be predominantly driven by inner values (deontological guilt) or by more interpersonal situations (altruistic guilt). The aim of this study was to investigate whether there is a distinct neurobiological substrate for these two expressions of guilt in healthy individuals. We first run two behavioral studies, recruiting a sample of 72 healthy volunteers, to validate a set of stimuli selectively evoking deontological and altruistic guilt, or basic control emotions (i.e., anger and sadness). Similar stimuli were reproduced in a event-related functional magnetic resonance imaging (fMRI) paradigm, to investigate the neural correlates of the same emotions, in a new sample of 22 healthy volunteers. We show that guilty emotions, compared to anger and sadness, activate specific brain areas (i.e., cingulate gyrus and medial frontal cortex) and that different neuronal networks are involved in each specific kind of guilt, with the insula selectively responding to deontological guilt stimuli. This study provides evidence for the existence of distinct neural circuits involved in different guilty feelings. This complex emotion might account for normal individual attitudes and deviant social behaviors. Moreover, an abnormal processing of specific guilt feelings might account for some psychopathological manifestation, such as obsessive-compulsive disorder and depression.

Altruism, spite and choosy females

Natural selection favours the genes which are able to introduce replicates of themselves in the next generation with higher certainty than do rival genes (Hamilton 1963). The fitness of an individual, it?s ability to produce future parents, depends on it?s own behaviour as well as on the behaviour of other individuals in the population. For instance, the intensity of competition an individual experience depends on the exploitation of resources by neighbours. The fitness is thus frequency dependent on what neighbours do. Behaviours can be classified according to the costs and benefits they have on the fitness of the behaver and it?s neighbours (Hamilton 1964, Hamilton 1975). According to this classification there exist four distinct social behaviours. (1) A gene confering the ability to use a new ressource is called selfish because it has a positive e_ect on the bearer of the gene but a negative e_ect on neighbours by the concomitant increase in competition. (2) An altruistic behaviour is defined as an action where an individual increases the fitness of a neighbour at the expense of it?s own. The e_ect is deleterious for the actor but positive for the receptor. (3) More surprinsingly, an individual might sacrifice a fraction of it?s ressources to harm another at no direct benefits. This spitefull behaviour incurs a cost for the actor but is also deleterious for the receptor. (4) Finally a cooperative behaviour breeds benefits for both actors and neighbours. In this thesis I will continue on the path traced by numerous evolutionnary biologist which attempt to fine tune our understanding of the evolution of social behaviours since Hamilton?s foundation (1963, 1964). A critical development over the last 40 years has been the realisation that competition between kin can partly or completely cancel out the role of relatedness as an agent favouring altruism (Wilson et al., 1992; Taylor, 1992a,b). Of importance is thus to determine the scale at which competition and altruism occur. One mechanism avoiding the complete dilution of relatedness by competition is the conditionnal expression of the social behaviors. Focus will be given in this thesis at the role played by di_erent recognition mechanism in paving the way to altruism (Komdeur and Hatchwell, 1999) when the population has a spatial structure. Further, the evolution of spite will also be considered in these settings. The thesis is fractionated into two parts. First, di_erent models promoting altruism cooperation and spite will be compared under the same theoretical umbrella. This is a rather informal and more personnal part of my thesis. It also serve as a justification and basis to "Altruism among kin and non-kin individuals" which is an article attempting to clas- sify the mechanisms leading to altruism and cooperation. Second, in the annexe, there are three research papers about kin selection, altruism and dispersal: "Is sociality driven by the costs of dispersal or the benefits of philopatry?: A role for kin-discrimination mechanism", "Altruism, dispersal and phenotype kin recognition" and "Inbreeding avoidance through kin recognition: choosy female boost male dispersal" this last paper incorporates kin recognition as an agent favoring sex-biased dispersal.

Une délicate rencontre entre savoirs autochtones "experts" : enjeux politiques interculturelles dans le domaine de la prévention de la violence à l'égard des femmes kichwa en Amazonie équatorienne

Cette thèse porte sur l'élaboration et la mise en pratique de politiques interculturelles dans le champ de la santé internationale, en se basant sur une ethnographie d'un programme de préven¬tion de la violence de genre dans le canton de Loreto, en Amazonie équatorienne, mis en place par la Croix-Rouge suisse et aujourd'hui géré de concert avec l'Etat équatorien et une organisation kichwa locale. Suivant une approche qui fait varier les échelles d'analyses pour articuler le niveau local, national et international, elle met en évidence les lieux d'intersection et les hiatus entre l'idéal d'interculturalité tel qu'il est conçu «par le haut» et les pratiques qui sont mises en oeuvre au quotidien par des professionnels de la santé et du développement métis équatoriens. Elle révèle ainsi qu'au-delà de l'idéal du respect des « différences culturelles autochtones » et de la symétrie entre les « cultures », les discours et les pratiques de ces professionnels consistent en une entreprise de normalisation et de moralisation des comportements des destinataires kichwa en matière de rapports de genre. Pour affiner ces analyses et dépasser une approche critique de la santé publique, cette thèse explore également les représentations et les pratiques des destinataires - femmes agents de santé et « bénéficiaires » kichwa du programme - en matière de violence et de rapports de genre. Elle montre ainsi que le transfert de normes et de valeurs via la santé publique fait l'objet de mul¬tiples processus d'appropriations, et explore les différentes d'interprétations, de négociations et d'instrumentalisations de la part des destinataires, tant au niveau individuel que collectif. -- Intercultural politics and the prevention of violence against kichwa women in the Ecuadorian Amazon This PhD thesis focuses on the development and application of intercultural policies in the field of international health. It is drawn on an ethnographic fieldwork conducted in canton Loreto, in the Ecuadorian Amazon, about a gender violence prevention program which was set up by the Swiss Red Cross and which is now managed in cooperation with the Ecuadorian State and a local kichwa organization. Following a multiple-scale analysis in order to articulate the local, national and international dynamics, it highlights the intersections and the gaps between, on the one hand, the the institutional prescriptions about the ideal of interculturality and on the other hand, the daily practices of Ecuadorian mestizo health and development profesionals. It reveals that beyond the ideal of respect for «indigenous cultural differences» and of symmetry between «cultures», the discourses and practices of these professionals consist of a normalizing and moralizing enter¬prise concerning the gendered and, more broadly, social behaviors of kichwa «beneficiaries». In order to refine the analysis and to go beyond a critical approach of public health, this thesis also explores the violence and gender relations representations and practices of kichwa women health workers and «beneficiaries», men and women. Thus it shows that the transfer of norms via public health is the subject of multiple processes of appropriation, interpretation, negotiation and instru¬mentalisation both on individual and collective levels by the «beneficiaries».

‘Green Consumption’ beyond mainstream economy: A discourse analysis

In contemporary society, green consumption is a popular concept. The life styles of people and consumption behaviors are moderated in accordance to the ‘green ideology’. The process of green consumption can be observed through social behaviors such as preference of bio foods, recycling, reusing, limiting the over consumption and using environmentally friendly transport systems. However, mainstream economic analyses on green consumption argued that consumer behaviors are due to the rational choice of individuality based on utility and self-preferences. The hypothesis of this paper on consumer behavior in green consumption is configured by discourses according to the discourse analysis.

Disability and Identity Processes

This article presents a reflection about the Disability like a human phenomenon, which needs not only new definitions if not a criticism point of view as a Concept, with the end of indicate representations forms not only for people with disabilities if not for the citizens in general. Considers discourses that identify arguments from social sciences, appearing the Disability like a differentiate condition between human beings, mainly for an exclusion process that announce social behaviors in relations with the persons with disabilities.

Caracterización de la Cultura Organizacional de Informatica Documental SAS

Actualmente, el estudio de la cultura organizacional se ha convertido en un tema de gran importancia para las empresas ya que, de acuerdo a que tan satisfecho este el empleado, esta tiene un impacto en el desempeño de la compañía, además se vuelve en un factor clave para el fracaso o el éxito de cada uno de los proyectos o tecnologías de gestión que implemente la organización. La cultura organizacional según el autor Carlos Eduardo Méndez Álvarez (2006) es: La conciencia colectiva que se expresa en el sistema de significados compartidos por los miembros de la organización que los identifica y diferencia de otros institucionalizando y estandarizando sus conductas sociales. Tales significados y comportamientos son determinados por el concepto que tiene el líder de la organización tiene sobre el hombre, la estructura, el sistema cultural y el clima organizacional así como por la interrelación y mutua influencia que existe entre estos. Basados en el concepto de este autor, se va a realizar el estudio de cultura organizacional en la empresa Informática Documental SAS, dedicada al manejo y control de documentación a nivel nacional, en el cual, se va a conocer una descripción detallada del comportamiento de los miembros de la organización.

A educação inclusiva e a hiperactividade no jardim de infância

RESUMO: Propomos com este trabalho conhecer e aprofundar conhecimentos, através duma investigação-acção, relativamente à problemática em estudo - Perturbação de Hiperactividade com Défice de Atenção (PHDA). Também procurámos mostrar, através da intervenção, que o educador pode auxiliar no desenvolvimento e aprendizagem de uma criança com um diagnóstico de PHDA. Realizámos uma pesquisa bibliográfica sobre esta Perturbação, com uma breve perspectiva histórica, sobre o que é a PHDA, o diagnóstico, os subtipos e problemas associados e a intervenção em crianças com esta problemática. Pesquisámos, também, estratégias educativas de como actuar a nível pedagógico com esta criança e com o grupo onde se encontra incluída. Demos uma grande centralidade ao trabalho empírico, através da pesquisa documental, observações, entrevistas e sociometria. De seguida, elaborámos um projecto de investigação-acção, para o grupo onde a criança está incluída, utilizando estratégias de educação inclusiva, de modo a colmatar problemas comportamentais e de aprendizagem, derivados de défices de atenção e de concentração do grupo, através do grupo. Todo este processo deu resultados positivos, a nível dos comportamentos sociais e das aprendizagens académicas do grupo e do aluno desencadeador do Trabalho Projecto. Obrigou a uma acção, reflexão, acção que desencadeou uma procura e experimentação sistemática para dar resposta aos problemas surgidos, o que ajudou ao meu desenvolvimento pessoal e profissional e a uma vontade de investir mais e melhor no desencadeamento de práticas de educação cada vez mais inclusivas. ABSTRACT: With this paper, we want to learn, using the investigation-action, about the team we are working with, that is Perturbation of Hyperactivity and Deficit of Attention (PHDA). We also want to show that it is possible to help the children with the PHDA in their learning process using the right intervention. We searched for different opinions on this team, its history, how to diagnostic it and the different problems that this children can have. We also search for different strategies to teach the students with this problem as well as the others of the group. We gave special attention to the empirical work. For this reason we used the documental research, the observation, interviews and sociometry. After this we prepared the action research project for the group of children that work with the PHDA child. To do so, we used different inclusion strategies so that we could help him improving his behavior and learning process using the help of other students. On the end we had positive results in the behavior and also in the learning process with the group and the student who we based this work on. We used action/reflection/action that helped us to find out about the PHDA and the different strategies to try to solve this problem. All of this helped me as a teacher and as a person. It gave me the will to keep looking for better and different inclusive strategies.

Facebook e inovação pedagógica : um projeto de autoformação

A investigadora fixou o objetivo de se atualizar a nível profissional, por autoformação. Considera ser relevante para o ensino que se aposte em estratégias /atividades inovadoras sob um ponto de vista pedagógico, assentes nas novas tecnologias. Neste contexto, a questão de partida foi: como pode a docente inovar na sua prática pedagógica com impacto no desenvolvimento das suas competências digitais e profissionais? Pode inovar, explorando, a nível educativo, as caraterísticas de uma rede social como o Facebook, que é intuitiva e permite o acesso por computador. Além disso, aposta na natureza ubíqua, desenhada para Tablet ou telemóvel, em mobilidade. Possibilita a comunicação síncrona e assíncrona. Pode ser rentabilizada em dois níveis: no da Web 1.0, para pesquisa e arquivo; e no da Web 2.0, para criação/cocriação. Nesta investigação, o paradigma da Web 2.0 facultou a conceção de uma Wiki e de outros produtos criativos. Sendo inábil em tecnologia digital, a docente investigadora pretendeu inverter a situação ao começar pelo Facebook, que se revelou uma forma muito pragmática de ir aprendendo, paulatinamente, a operar outras ferramentas digitais e de consolidar uma autoformação em espiral ascendente. O Trabalho de Projeto, de que ora se lavra este relatório, seguiu a metodologia de investigação-ação, pelo modelo de Whitehead (1989). Foram cinco fases distintas: desde a identificação do problema até à sua superação, passando pelas fases intermédias de planificação do trabalho e de implementação. A última fase foi a reformulação, isto é, a planificação do ano letivo seguinte, com base na experimentação anterior e nos resultados obtidos. Dos resultados obtidos, destacam-se os seguintes: os discentes empenharam-se nas inovações digital e pedagógica porque compreenderam que a docente as concebeu para eles e eram adequadas às suas capacidades; elucidaram a docente, quando esta teve dúvidas de ordem digital; aprovaram o método eclético que concilia o tradicional com o moderno, sem exageros; apreciaram que a docente se implicasse, conferindo um cunho pessoal às aulas; aceitaram bem a entrada do Facebook em meio escolar, com a associação do telemóvel, para partilha de informação e de conhecimento; o Facebook ajudou a docente a desenvolver as aprendizagens tecnológicas e a comunicar com os alunos; os intervenientes reconheceram que podem criar produtos propositadamente para exibir na página, entrando portanto, na Web 2.0.

A Participação da Marinha Grande no 18 de Janeiro de 1934

Portugal viveu um dos períodos mais sombrios da sua História no Século XX, com o regime autoritário liderado por António de Oliveira Salazar, que governou o país com «mão de ferro» durante mais de três décadas, concretamente entre 1933 e 1968, uma vez que se considera que há alteração de regime sempre que muda o referencial e a Constituição do Estado Novo é de 1933. Para além da ausência de democracia e liberdade, o povo português conviveu com a fome e a ignorância durante décadas, foi perseguido e torturado nas prisões continentais e ultramarinas, nomeadamente no Tarrafal, que se localiza no arquipélago de Cabo Verde. Em 18 de janeiro de 1934, o movimento operário português saiu à rua em várias cidades e vilas de Portugal, entre as quais a Marinha Grande. Na origem do movimento revolucionário esteve a decisão do Presidente do Conselho, através da Constituição de 1933, de impedir o funcionamento de sindicatos livres. Contudo, aquela que se previa ser unicamente uma greve geral contra a decisão do regime acabou por ir mais além, sobretudo na cidade vidreira, onde o quartel da GNR foi tomado, tal como a estação dos Correios, existindo ainda hoje dúvidas sobre a constituição de um soviete. Mais de sete décadas após o ato insurrecional continua muito por esclarecer. Esta Dissertação visa, precisamente, obter respostas a questões tão diversas como quem esteve realmente por detrás do 18 de janeiro de 1934 na Marinha Grande, que consequências teve para a política do Estado Novo e, finalmente, que importância teve na conjuntura. Importa ainda esclarecer por que razão esta derrota do movimento operário português é hoje recordada, com pompa e circunstância, na Marinha Grande, como se tivesse sido uma vitória. De facto, na atualidade, fala-se de uma jornada heroica, mas o Partido Comunista Português praticamente ignorou esse movimento até abril de 1974 e o seu líder à época, Bento Gonçalves (1971, p. 138), apelidou-o de “anarqueirada”.

Differential brain activity during emotional versus nonemotional reversal learning

The ability to change an established stimulus–behavior association based on feedback is critical for adaptive social behaviors. This ability has been examined in reversal learning tasks, where participants first learn a stimulus–response association (e.g., select a particular object to get a reward) and then need to alter their response when reinforcement contingencies change. Although substantial evidence demonstrates that the OFC is a critical region for reversal learning, previous studies have not distinguished reversal learning for emotional associations from neutral associations. The current study examined whether OFC plays similar roles in emotional versus neutral reversal learning. The OFC showed greater activity during reversals of stimulus–outcome associations for negative outcomes than for neutral outcomes. Similar OFC activity was also observed during reversals involving positive outcomes. Furthermore, OFC activity is more inversely correlated with amygdala activity during negative reversals than during neutral reversals. Overall, our results indicate that the OFC is more activated by emotional than neutral reversal learning and that OFC's interactions with the amygdala are greater for negative than neutral reversal learning.
