Restoration ecology of coastal lagoons: new methods for the prediction of ecological trajectories and economic valuation

Conservation of the seven lagoons of the Palavas complex (southern France) has been severely impaired by nutrient over-enrichment during at least four decades. The effluents of the Montpellier wastewater treatment plant (WWTP) represented the main nutrient input. To improve the water quality of these lagoons, this WWTP was renovated and upgraded and, since the end of 2005, its effluents have been discharged 11 km offshore into the Mediterranean (total investment €150 M). Possibilities of ecosystem restoration as part of a conservation programme were explored by a focus group of experts. Their tasks were: (i) to evaluate the impact of the reduction of the nutrient input; (ii) if necessary, to design additional measures for an active restoration programme; and (iii) to predict ecosystem trajectories for the different cases. Extension of Magnoliophyta meadows can be taken as a proxy for ecosystem restoration as they favour the increase of several fish (seahorse) and bird (ducks, swans, herons) species, albeit they represent a trade-off for greater flamingos. Additional measures for active ecosystem restoration were only recommended for the most impaired lagoon Méjean, while the least impaired lagoon Ingril is already on a trajectory of spontaneous recovery. A multiple contingent valuation considering four different management options for the Méjean lagoon was used in a pilot study based on face-to-face interviews with 159 respondents. Three levels of ecosystem restoration were expressed in terms of recovery of Magnoliophyta meadows, including their impact on emblematic fish and avifauna. These were combined with different options for access (status quo, increasing access, increasing access with measures to reduce disturbance). The results show a willingness of local populations to pay per year about €25 for the highest level of ecological restoration, while they were only willing to allocate about €5 for additional footpaths and hides.

Odwrót od rozwoju: kontrowersyjna czy obiecująca zmiana paradygmatu wczesnej edukacji

The article presents three approaches to the conceptualisation of development as a category which describes the dynamics of the biography of man, which the author defines as: universalisation, contextualisation / relativism, and problematisation / negation. Emphasis is laid on a shift in thinking about the child and childhood, to be observed in the post-structural analyses contingent on the thought of Michel Foucault and a critique of developmental psychology which is developing in the world, but has been absent from Poland so far. The strongest critique of both these perspectives is directed against the standardisation measures for which individuality, specificity and diversity become a deviation from the norm. The article shows how strong arguments showing the controversy of development perceived in this way have been collected and how debatable the category of development as such is.

Contrasting effects of historical contingency on phenotypic and genomic trajectories during a two-step evolution experiment with bacteria

Background The impact of historical contingency, i.e. the past evolutionary history of a population, on further adaptation is mostly unknown at both the phenotypic and genomic levels. We addressed this question using a two-step evolution experiment. First, replicate populations of Escherichia coli were propagated in four different environmental conditions for 1000 generations. Then, all replicate populations were transferred and propagated for further 1000 generations to a single new environment. Results Using this two-step experimental evolution strategy, we investigated, at both the phenotypic and genomic levels, whether and how adaptation in the initial historical environments impacted evolutionary trajectories in a new environment. We showed that both the growth rate and fitness of the evolved populations obtained after the second step of evolution were contingent upon past evolutionary history. In contrast however, the genes that were modified during the second step of evolution were independent from the previous history of the populations. Conclusions Our work suggests that historical contingency affects phenotypic adaptation to a new environment. This was however not reflected at the genomic level implying complex relationships between environmental factors and the genotype-to-phenotype map.

Revisions, and Quiddities

I used to think of the connection between a particular and a universal that it instantiates as a contingent one. Now I think that this is not quite right. This revision, as I now see it, is not a very large one. I still think that the states of affairs (Russell’s facts in his great Lectures on Logical Atomism) that unite particulars and universals are contingent beings. But the connection within states of affairs is, in a certain way, necessary.

On the brink of madness: Leituras do tema da loucura na obra pré-heteronímica de Fernando Pessoa

O tema da loucura na obra pessoana tem sido objecto de várias aproximações interpretativas, decorrentes da multiplicidade de textos que fazem eco do fenómeno e da sua persistência enquanto topos ao longo de praticamente toda a sua produção. Na sua acepção literal, manteve constantes interferências com a dimensão empírica do autor sobretudo quando sustentadas na contingência de certos textos basilares, os quais têm vindo a ser questionados quanto ao seu valor estritamente testemunhal. Como fenómeno desde cedo relacionado com a criação artística, a loucura surge neste estudo não apenas na representatividade da condição distintiva do sujeito criador mas ainda como figuração da contingência que envolve qualquer acto criativo que tome a linguagem na sua dimensão essencialmente metafórica e ambígua. Neste sentido, o presente trabalho pretende a abertura de várias vias de leitura do fenómeno através da análise crítica dos vocabulários relativos a diferentes âmbitos e concepções de loucura e a sua relação com o génio (capítulos I e II), focando o seu interesse no que diz respeito a alguma produção pessoana pré-heteronímica, nomeadamente Charles Robert Anon, Alexander Search (capítulo III) e Jean Seul de Méluret (capítulo IV), a que acrescentaremos o Primeiro Fausto (capítulo IV), de modo a conseguirmos estabelecer uma possível relação entre as primeiras experiências de alterização e a descoberta simultânea da irredutibilidade do discurso literário face a tentativas de literalização e de racionalização da linguagem, defendidas por outros modelos (paradigma biologista). A identificação da ambiguidade e da ironia nas suas mais variadas acepções como componentes essenciais da aprendizagem do valor contingente do processo de criação contribuirá tanto para a definição da autonomização da literatura como para a redescrição moderna do sujeito criador, paradoxalmente investido do pathos criativo anunciado no Romantismo e confrontando-se com os seus limites, que corresponderão aos da própria linguagem, situação de crise de que a figuração do louco lúcido será um dos tópicos mais produtivos. ABSTRACT: The theme of madness in the Pessoa work has been the subject of several interpretive approaches, from the multiplicity of texts that echo the phenomenon and its persistence as a topos priority over virtually all its production. ln its physiological sense, remained constant interference with the empirical dimension of the author when sustained in the contingency of certain basic texts that have been questioned as to their strictly testimonial value. As early phenomenon associated with artistic creation, the madness in this study is not only representative in the distinctive condition of the subject creator but also as the contingency figuration involving any creative act to take the language mainly in its essential metaphorical and ambiguous dimension. Accordingly, this work intends to open several analysis manners of the phenomenon through critical analysis of vocabularies for different areas and concepts of madness and its special relationship with the genius (Chapters I and II), focusing its interest in respect to some of the previous-heteronomy Pessoa production, including Charles Robert Anon, Alexander Search (Chapter III) and Jean Seul de Méluret (Chapter IV), and the Primeiro Fausto (Chapter IV), among others, to establish a possible relationship between changing early experiences and the discovery simultaneous literary discourse of irreducibility in the face of the attempts of literacy and the rationalization of language defended by other models (biologist paradigm). The identification of the ambiguity and irony in its many different meanings as essential components of learning the contingent value of the creation process which will contribute to the definition of empowerment in the literature as to the redescription of the modem subject creator that paradoxically had the creative pathos announced in Romanticism and from the confrontation with its limits, which will correspond to the language itself, the crisis situation from which the mad-lucid figuration will be one of the most productive topics.

INVESTIGATING THE POSTWAR DECLINE OF RACE IN SCIENCE

Race as a biological category has a long and troubling history as a central ordering concept in the life and human sciences. The mid-twentieth century has been marked as the point where biological concepts of race began to disappear from science. However, biological definitions of race continue to penetrate scientific understandings and uses of racial concepts. Using the theoretical frameworks of critical race theory and science and technology studies and an in-depth case study of the discipline of immunology, this dissertation explores the appearance of a mid-century decline of concepts of biological race in science. I argue that biological concepts of race did not disappear in the middle of the twentieth century but were reconfigured into genetic language. In this dissertation I offer a periodization of biological concepts of race. Focusing on continuities and the effects of contingent events, I compare how biological concepts of race articulate with racisms in each period. The discipline of immunology serves as a case study that demonstrates how biological concepts of race did not decline in the postwar era, but were translated into the language of genetics and populations. I argue that the appearance of a decline was due to events both internal and external to the science of immunology. By framing the mid-twentieth century disappearance of race in science as the triumph of an antiracist racial project of science, it allows us to more clearly see the more recent resurgence of race in science as a recycling of older themes and tactics from the racist science projects of the past.

Family’s Financial Support as Poisoned Gift: A Family Embeddedness View on Entrepreneurial Intentions

How is expected financial support by the family related to individuals' entrepreneurial intentions? By drawing on family embeddedness literature we take a novel perspective and argue that the stronger the financial support that individuals will receive from their family to start a new venture is, the lower is the likelihood that they actually form entrepreneurial intentions. We confirm this prediction on a sample of 23,866 individuals from 19 countries and find in addition that the negative relationship between the expected financial support by the family and entrepreneurial intentions is contingent on the level of family cohesion and individuals' entrepreneurial self-efficacy. These results add valuable knowledge to the entrepreneurship and family embeddedness literature.

Fluxo de Informação Financeira entre o Território Nacional e os Teatros de Operaçõe s: Abordagem Sociocrítica em contexto de mudança

O presente Trabalho de Investigação Aplicada encontra-se subordinado ao tema “Fluxo de Informação Financeira entre o Território Nacional e os Teatros de Operações: Abordagem Sociocrítica em contexto de mudança.”. Tendo em conta o contexto económico que o país atravessa, e que indiretamente afeta as organizações do Estado, através das consequentes reduções orçamentais, torna-se imprescindível que exista um aproveitamento dos recursos muito mais eficiente e eficaz. Neste contexto e face à existência em Território Nacional do Sistema Integrado de Gestão nas Instituições do Ministério de Defesa Nacional, nomeadamente no Exército, revelou-se indispensável a implementação desta ferramenta de gestão nas Forças Nacionais Destacadas dos Teatros de Operações. Desta forma, o objetivo geral desta investigação é identificar as limitações e potencialidades que a recente implementação do Sistema Integrado de Gestão nos Teatros de Operações provocou no desempenho das funções dos Oficiais de Finanças. Neste trabalho procuramos ainda identificar o impacto da harmonização dos procedimentos contabilísticos na execução orçamental, as melhorias do processo de tomada de decisão, a harmonização na realização do relato financeiro, e consequentes alterações nos procedimentos de mudança de contingente, bem como as alterações na execução das diferentes fases do Registo Contabilístico do Fundo de Maneio. Para a elaboração desta investigação aplicou-se o método hipotético-dedutivo, sendo desenvolvida segundo objetivos descritivos e exploratórios com o intuito de identificar, explorar e descrever as limitações e potencialidades da implementação do Sistema Integrado de Gestão na Força Nacional Destacada do Kosovo, recorrendo ao estudo exploratório/descritivo, enquadrando-se ainda na categoria do Estudo de Caso. No sentido de atingir os objetivos propostos inicialmente foram elaborados e aplicados diferentes inquéritos por entrevista. Após a análise e discussão dos resultados foi possível concluir que a informação contabilística disponível em tempo real, de forma imediata e oportuna, permite aos Oficiais de Finanças serem mais eficazes e assertivos no aconselhamento ao Comandante, assim como origina uma melhor e mais célere tomada de decisão em Teatro de Operações e para toda cadeia de comando em Território Nacional. Outra grande mais-valia foi a possibilidade de reduzir significativamente o Fundo de Maneio. Alcançado o final desta investigação, foi possível concluir que não existem limitações do Sistema Integrado de Gestão nos Teatros de Operações que não existam em Território Nacional, sendo dessa forma possível constatar que as possíveis melhorias são a implementação da contabilidade analítica e a integração de todas as áreas desta ferramenta, permitindo tirar total partido da mesma.

A natural extension of the classical envelope theorem in vector differential programming

The aim of this paper is to extend the classical envelope theorem from scalar to vector differential programming. The obtained result allows us to measure the quantitative behaviour of a certain set of optimal values (not necessarily a singleton) characterized to become minimum when the objective function is composed with a positive function, according to changes of any of the parameters which appear in the constraints. We show that the sensitivity of the program depends on a Lagrange multiplier and its sensitivity.

Work, Professional Development And Teaching Commitment: Deconstructing Meanings

The paper we present is part of the research project "The professional identity of teacher studies", that we are development for last 3 years. The third phase of this research put the focus on the experience of job placement of novel teachers, graduated no more than 5 years. We work with focal groups and professional experience and teacher education accounts of teachers implied in this research. Also, for any teachers, we do biographical interviews to deepen on processes of construction of professional identity. In this paper we present the Ana Belen History, a female teacher of pre-school education with an experience of 4 years in school, working in a urban school with students in risk of exclusion. This school have a educative project, commitment with the neighbourhood, joint with the community and other social groups. Ana Belen story, from professional perspective, is linked with the social politic and educational commitment of this school. Our interest is focused in the comprehension of professional identity that Ana Belen has gone forging along her personal story and how her education and job placement has contributed for it. Also we are interested in knowing how early professional experiences have influenced in her professional development as teacher. Specifically we ask ourselves about what influence have for her professional identity, that her career starts in this particular school. In consequence, this paper leads us to question the current teacher education model. In particular we are interested on the kind of professional experience that have place and, so, the kinds of commitments that enables. We understand that frameworks in which professional education and experience have place are relevant to enable more or less transformer understandings about teaching. From conceptual perspective this paper adopts a socio-critical point of view (Gergen, 1985; Kincheloe, 2001; Wenger, 1988, etc.). We understand that teaching has to be analysing according work contexts and personal stories of teachers, because we face processes historical and collective building. Teaching is the result of action of their actors, over time, and in specific stage. So, with this research we intend to break with the old gap between pre and in-service education. We think that both of them are part of the same process and are formed according similar logical; although scenes change. We understand that they are part of a continuous process in which is giving sense to different and complex settings where teaching profession is built, but they are not differenced and independent stages. The teacher work, so, is subject to particular conditions, generated from such different fields as institutional, corporative, cultural, social, political, moral, etc. It displays a kaleidoscopic view on space, time, context, ... These are the axis in which the teaching is formed, from the complexity and heterogeneity. How this complexity is articulated results in different ways to face the teacher work, according different personal and professional stories. The teacher acts with subjects in instituted contexts from relationships he has with them, which gives a situated and contingent character. But, these contexts are strongly structured and ruled according centralized and generalized positions; which is, at the very least, paradoxical. Possibly, from our point of view, same of the crisis of teaching have to explain from this paradoxical perspective and the conflict, which characterize this job (Rivas, Leite y Cortés, 2011)
