Low demographic variability in wild primate populations: fitness impacts of variation, covariation, and serial correlation in vital rates.

In a stochastic environment, long-term fitness can be influenced by variation, covariation, and serial correlation in vital rates (survival and fertility). Yet no study of an animal population has parsed the contributions of these three aspects of variability to long-term fitness. We do so using a unique database that includes complete life-history information for wild-living individuals of seven primate species that have been the subjects of long-term (22-45 years) behavioral studies. Overall, the estimated levels of vital rate variation had only minor effects on long-term fitness, and the effects of vital rate covariation and serial correlation were even weaker. To explore why, we compared estimated variances of adult survival in primates with values for other vertebrates in the literature and found that adult survival is significantly less variable in primates than it is in the other vertebrates. Finally, we tested the prediction that adult survival, because it more strongly influences fitness in a constant environment, will be less variable than newborn survival, and we found only mixed support for the prediction. Our results suggest that wild primates may be buffered against detrimental fitness effects of environmental stochasticity by their highly developed cognitive abilities, social networks, and broad, flexible diets.

Influence of the thalamus on spatial visual processing in frontal cortex.

Each of our movements activates our own sensory receptors, and therefore keeping track of self-movement is a necessary part of analysing sensory input. One way in which the brain keeps track of self-movement is by monitoring an internal copy, or corollary discharge, of motor commands. This concept could explain why we perceive a stable visual world despite our frequent quick, or saccadic, eye movements: corollary discharge about each saccade would permit the visual system to ignore saccade-induced visual changes. The critical missing link has been the connection between corollary discharge and visual processing. Here we show that such a link is formed by a corollary discharge from the thalamus that targets the frontal cortex. In the thalamus, neurons in the mediodorsal nucleus relay a corollary discharge of saccades from the midbrain superior colliculus to the cortical frontal eye field. In the frontal eye field, neurons use corollary discharge to shift their visual receptive fields spatially before saccades. We tested the hypothesis that these two components-a pathway for corollary discharge and neurons with shifting receptive fields-form a circuit in which the corollary discharge drives the shift. First we showed that the known spatial and temporal properties of the corollary discharge predict the dynamic changes in spatial visual processing of cortical neurons when saccades are made. Then we moved from this correlation to causation by isolating single cortical neurons and showing that their spatial visual processing is impaired when corollary discharge from the thalamus is interrupted. Thus the visual processing of frontal neurons is spatiotemporally matched with, and functionally dependent on, corollary discharge input from the thalamus. These experiments establish the first link between corollary discharge and visual processing, delineate a brain circuit that is well suited for mediating visual stability, and provide a framework for studying corollary discharge in other sensory systems.

Productive Synergies in the City

The chapter focuses on the development of sustainable growing infrastructure in the city at two scales. Firstly the development of a large-scale city wide fuel productive landscape through the development of algae arrays in Liverpool and their connection through urban agriculture systems to develop a closed-cycle food and energy system where waste is food and secondly a hyper-localised neighbourhood food production system in Salford UK that utilises a closed cycle aquaponic system to re-invigorate an urban food desert.

The author develops a three-part model for the implementation of urban agriculture based on hardware (the technological system), software (the biological components) and interface (the links to food and other social networks). The conclusion being that it is possible to develop urban agriculture in cities if their implementation is seen as a process, rather than a static design. Also that as the benefits of such systems are wider than purely the physical outputs of the system in terms of energy and food, and thus we should re-evaluate the purely economic model of appraisal to include these.

X-ray driven evaporation of exoplanet atmospheres: discovery of a uniquely suited test system

The evaporation of exoplanetary atmospheres is thought to be driven by high-energy irradiation. However, the actual mass loss rates are not well constrained. Co-I Kipping has recently discovered that the star KOI-314, an M1V dwarf at 65 pc distance, is orbited by two earth-sized planets, the inner one of them rocky and the outer one gaseous (P_orb = 14d and 23d). Other recent works have shown an abundance of small rocky planets in very close orbits around their host stars, suggesting that the stellar high-energy irradiation evaporates away gaseous envelopes. KOI-314 is the first nearby system in which earth-sized planets of both types are detected, allowing us to constrain the efficiency of planetary evaporation if the stellar X-ray irradiation is measured. We therefore propose a 10 ks Chandra ACIS-S pointing to determine the stellar X-ray luminosity and hardness ratio. The accuracy of the orbital solution decreases quickly due to Transit-Timing Variations, which is why we ask for DDT.

A desocultação dos saberes profissionais: um espaço do ensino superior

The practical knowledge has characteristics of a process with peculiar idiosyncrasies that require disruption with preconceived ideas, dialogue, negotiation and joint action. The knowledge underlying remains unclear despite of being what informs decision making. It is academia’s responsibility to unveil and nominate knowledge and that is the reason why we conducted two studies with clinical nurses. The aim is to understand the social representation that nurses make of their knowledge about nursing and analyze their clinical practices. In one of the studies, based on the theoretical-methodological referential of social representations, we used the technique of free association of words with the stimulus “knowledge in nursing”. In another study, developed within a naturalistic context and under the “Grounded Theory” referential, we used non-participative observation and explanatory interviews. From the first study we identified the structure of social representations of knowledge in nursing, from which emerged the central core constituted by four elements (Investigation, Wisdom, help Relation, Competence) and a second periphery with one element (Reflection). With the second study we identified that decisions are made within a dynamic, systematic and continuous process of diagnostic evaluation and clinical intervention using the various types of knowledge (e.g. clinic, experiential, scientific, personal). We concluded that the various types of knowledge in nursing, represented by the expressions mentioned above, are systematically and creatively mobilized within the dynamic process of diagnostic evaluation and clinical intervention. It is therefore important to unveil and nominate the different knowledge implicit in the clinical practice and Academia should be responsible for that task.

Comunicação organizacional e identidade colectiva num agrupamento de escolas

O reforço e a diversificação do investimento na comunicação por parte das instituições educativas são discutidos neste estudo como uma das consequências da nova gestão pública. Tendo em vista a ‘qualidade’ e a ‘eficácia’ das suas prestações, as escolas têm procurado tornar-se mais dialogantes, assumindo a aposta na comunicação organizacional como parte integrante de uma estratégia empreendedora, que lhes tem vindo a conferir uma nova identidade colectiva unificada em torno dos valores neoliberais. Não obstante, os sistemas de comunicação criados são mais complexos do que se poderia supor. Revelando a influência de pressões híbridas, estes sistemas transformaram-se num contexto mediador da mudança embutido em novas concepções de escola e dos novos mandatos para a educação (assim legitimados interna e externamente), surgindo, ao mesmo tempo, como o locus de produção de novas identidades. Tal acontece porque a comunicação constitui o ponto de convergência entre as diferentes políticas educativas e as práticas localmente adoptadas na sequência de um processo de interpretação criativa das diferentes pressões. É este o sentido com que afirmamos que a comunicação se constitui numa meta-ideia ao serviço da ‘qualidade’, ainda que esta possa ser perspectivada a partir do ideal burocrático da organização (como sinónimo de eficiência administrativa), do ideal profissional (centrada no processo de ensino-aprendizagem) ou do ideal empreendedor (valorizando a capacidade de resposta às solicitações do mercado). Os dados empíricos, que sustentaram o nosso estudo, resultaram da observação do quotidiano de um agrupamento de escolas do ensinobásico e dos testemunhos recolhidos, ao longo de três anos, nesta comunidade educativa. Recorrendo ao estudo de caso como estratégia de investigação enveredámos inicialmente, num contexto de descoberta, pela realização de observações ‘desarmadas e naturais’. Usámos, posteriormente, a análise documental, a entrevista e o questionário na recolha de informação complementar, o que, mediante o cruzamento de métodos de análise qualitativa e quantitativa, nos permitiu tirar partido da triangulação dos dados. Os resultados obtidos apontam para a centralidade dos processos de comunicação na transformação induzida pela nova gestão pública e para o desenvolvimento de uma matriz discursiva bilinguista, que procura harmonizar os imperativos de ‘mercado’ com o discurso pedagógico e com modelos burocrático-profissionais de organização.

Qualidade de vida e doença mental

Atendendo à conjuntura nacional e internacional que norteia a saúde mental e psiquiatria, a Qualidade de Vida (QDV) das pessoas com doença mental torna-se uma área fundamental de investigação, tendo em conta a sua inquestionável importância na aferição de medidas de intervenção. Um facto observável relaciona-se com um interesse crescente nos últimos anos na QDV da pessoa com doença mental como objeto de investigação. Estudos apontam para que as pessoas com doença mental percecionem a sua QDV inferior às pessoas sem doença mental e/ou com doenças físicas. Esta investigação foi realizada com base em três estudos. O Estudo I pretendeu estudar relações entre variáveis sociodemográficas e clínicas e a QDV de pessoas (n = 39) com doenças do humor (Depressão Major, Distimia, Doença Bipolar e Perturbações Depressivas Sem Outra Especificação). Para isso, foram utilizados o WHOQOL-Bref, o Índice de Graffar, um Questionário de Dados Sociodemográficos e Clínicos e um Guia de Observação. Os dados foram recolhidos no domicílio dos sujeitos. No Estudo II compararam-se diferenças de QDV em duas amostras independentes: sujeitos com doenças do humor (n = 39) e sujeitos sem doença mental diagnosticada (n = 39). Utilizaram-se os mesmos instrumentos do Estudo I exceto o Guia de Observação. Nestes dois estudos os dados foram tratados recorrendo ao IBM SPSS Statistics, versão 19.0. O Estudo III teve como objetivo recolher dados sobre as narrativas dos sujeitos com doença mental e sobre o conhecimento sobre a Rede Nacional de Cuidados Continuados e Integrados de Saúde Mental (RNCCISM). Para esta segunda parte do objetivo foi utilizada uma amostra de profissionais de saúde mental (n = 42) que respondeu a um Questionário sobre a RNCCISM construído para o efeito. Este Instrumento foi validado e do qual resultou uma variável final: “avaliação do conhecimento sobre a RNCCISM”. Os resultados desta pesquisa sugeriram, pelo Estudo I, que a QDV difere em função da doença apresentada pelos sujeitos; encontraram-se também diferenças em relação à idade, sexo, escolaridade, classe social, estado civil e transportes utilizados para a consulta de especialidade. Pelo Estudo II, os resultados indicaram-nos diferenças entre a QDV nos dois grupos, sendo que, o Grupo com doença do humor apresenta scores mas baixos em todos os domínios do WHOOL-Bref que o Grupo sem doença mental diagnosticada. Os dados do EstudoIII sugeriram-nos: i) no primeiro momento, uma reflexão que girou em torno de cinco eixos: o sofrimento; a estigmatização; os eventos de vida perturbadores; o modelo de tratamento adotado pelos profissionais; e o acompanhamento das pessoas com doença mental; ii) no segundo momento, que os enfermeiros são os que, em média, possuíam um score de conhecimento sobre a RNCCISM mais baixo. Esta investigação sugeriu que a QDV das pessoas com doença mental é baixa, indicando algumas relações entre algumas variáveis. Durante o seu desenvolvimento, pretendemos também reforçar a necessidade do envolvimento de todos os profissionais da saúde nas alterações preconizadas, o que permite intervir de forma mais informada. Porque, durante este percurso surgiram dificuldades sérias de acesso à amostra clínica, esta tese chama ainda a atenção para a importância da investigação em saúde mental e psiquiatria e para as formalidades de acesso aos dados que a podem condicionar. De facto, ao assumirmos a QDV como uma medida de resultado em saúde, torna-se importante, por um lado, aprofundar a investigação neste domínio e, por outro, e pelo conhecimento de que já dispomos, equacionar de forma efetiva novas modalidades de intervenção, contribuindo para um plano terapêutico mais amplo, pondo em prática uma filosofia de cuidados mais abrangente e de continuidade, implementando as politicas comunitárias e globais preconizadas para a prestação de cuidados em saúde mental e psiquiatria.

Factoring in family freight forwarder company: case study

Each freight forwarder company must independently determine whether factoring is the right choice for them and if will pay off. If the factoring as a financial method would not be economically viable, it certainly would not exist. There are several different financing methods, which are more or less useful. However, not all of them are appropriate for every company, just like all buyers do not represent equal risks for the suppliers. The same buyer can pay one supplier within the agreed period, and not pay the other supplier at all. Still, the most important elements are the agreement made with the customer, the method of insuring ourselves and the method of monitoring the implementation of the agreements. Problems rarely occur overnight and that is why we have to constantly supervise our buyers; otherwise account receivables can occur. My thesis contributes to the ongoing research into how the use of factoring within the Slovenian economic environment can help a small freight forwarder company to grow. In effect, the specific characteristics of the Slovenian economic, legal and institutional environment make such an analysis an interesting one to explore. I used data from a family freight forwarder company TOP Hrvatin in drugi d.n.o. in order to establish future company growth by applying factoring as a right choice of financing. After applying all the data and preparing the company's financial plan, my results suggest that factoring is not the right choice for financing future investments for this particular freight forwarder business. Furthermore, the results even show that factoring is an extremely undeveloped financing method in Slovenia and that practically there is no legal base for its use.

Representations of Portugal in Herman Hesse

The aim of my research is to answer the question: How is Portugal seen by non-Portuguese fictionists? The main reason why I chose this research line is the following: Portuguese essayists like Eduardo Lourenço and José Gil (2005) focus their attention on the image or representation of Portugal as conceived by the Portuguese; indeed there is a tendency in Portuguese cultural studies (and, to a certain extent, also in Portuguese philosophical studies) to focus on studying the so-called ‗portugalidade‘ (portugueseness), i.e., the essence of being Portuguese. In my view, the problem with the studies I have been referring to is that everything is self-referential, and if ‗portugueseness‘ is an issue, then it might be useful, when dealing with it, to separate subject from object of observation. That is the reason why we, in the CEI (Centro de Estudos Interculturais), decided to start this research line, which is an inversion in the current tendency of the studies about ‗portugueseness‘: instead of studying the image or representation of Portugal by the Portuguese, my task is to study the image or representation of Portugal by the non-Portuguese, in this case, in non-Portuguese fiction. For the present paper I selected three writers of the 20th century: the German Hermann Hesse and the North-Americans Philip Roth and Paul Auster

¿La edad de la política? Balanche Historiográfico de los estudios sobre comunicación e información política en la sociedad ibérica moderna

Los estudios sobre política y su impacto y circulación entre la sociedad moderna, han solido limitar su expansión a un número reducido de personas del entorno más próximo a los grandes actores cortesanos frente a la tradicional “indiferencia” del común. Sin embargo, gracias a la renovación de la historiografía de lo político y a su interés por áreas culturales y sociales ajenas a su tradicional consideración, en las últimas décadas se ha descubierto un interesante terreno de experiencias políticas que nos puede servir como atalaya para conocer la difusión de la información sobre los hechos políticos también entre “gente corriente”. A nuestro juicio, es un momento adecuado para evaluar el desarrollo de un fenómeno historiográfico carente de cierta sistematicidad, razón por la que planteamos este balance crítico y analítico sobre la sociedad ibérica del Antiguo Régimen.

Le droit d'auteur sur la mise en scène

À la lecture de la Loi sur le droit d'auteur, il n'est pas clair que la mise en scène y soit protégée. C'est pourquoi nous nous questionnons sur la qualification juridique la plus adéquate pour la mise en scène. Le metteur en scène est-il un artiste-interprète ou un auteur? Après avoir étudié les caractéristiques artistiques des mises en scène, par types de productions et à la lumière de facteurs faisant varier la latitude du metteur en scène, nous étudions les différentes possibilités de qualification juridique de la mise en scène. Les possibilités sont vastes, car le metteur en scène évolue dans un cadre comprenant plusieurs intervenants. De plus, la mise en scène rencontre deux obstacles caractéristiques à sa qualification juridique en droit d'auteur: la fixation et l'originalité. Nous en venons à la conclusion que le metteur en scène est un auteur, car chacun des aspects de la mise en scène serait protégeable sous différentes qualifications juridiques.
