We present the results of a multiple organizational level analysis conceived to identify acclimative/ adaptive strategies exhibited by the seagrass Posidonia oceanica to the daily uctuations in the light environment, at contrasting depths. We assessed changes in photophysiological parameters, leaf respiration, pigments, and protein and mRNA expression levels. The results show that the diel oscillations of P. oceanica photophysiological and respiratory responses were related to transcripts and proteins expression of the genes involved in those processes and that there was a response asynchrony between shallow and deep plants probably caused by the strong di erences in the light environment. The photochemical pathway of energy use was more e ective in shallow plants due to higher light availability, but these plants needed more investment in photoprotection and photorepair, requiring higher translation and protein synthesis than deep plants. The genetic di erentiation between deep and shallow stands suggests the existence of locally adapted genotypes to contrasting light environments. The depth-speci c diel rhythms of photosynthetic and respiratory processes, from molecular to physiological levels, must be considered in the management and conservation of these key coastal ecosystems.

This paper presents an argument in favor of a “phenomenological” approach to intentionality. This approach, as I see it, involves the view that intentional facts are better expressed with the help of appearance words (“seems”, “appears”, “is similar to”, etc.). By contrast, what I call the “intentionalist approach” assumes that intentional facts are better expressed by intentional verbs. The argument is as follows. First, it is well-known that the use of intentional verbs to express typically intentional facts generates anomalies with respect to existential generalization, substitution of identicals, and the principle of excluded middle. Secondly, I argue that the use of appearance words does not generate the same anomalies, which suggests that appearance words are more appropriate to describe intentional facts. This, I conclude, is an argument for preferring the phenomenological to the intentionalist approach to intentionality. [less ▲]

This study investigated the ability of individuals with disordered gambling to imagine future events. Problem gamblers (n=35) and control participants (n=35) were asked to imagine positive and negative future events for three temporal distances (one week, one year, 5-10years). Then, a variety of phenomenological aspects of their future thoughts (e.g., sensory and contextual details, autonoetic consciousness) were rated. Compared to control subjects, problem gamblers generated fewer positive and negative events across all temporal distances, an impairment that was correlated to verbal fluency scores. Furthermore, problem gamblers rated imagined events as containing fewer sensory and contextual details, and lacking autonoetic consciousness. These findings demonstrate that problem gambling is associated with a reduced future-oriented mental time travel ability and, in particular, with diminished autonoetic consciousness when imagining future events.

Adhesion is an important phenomenon in the context of MEMS for which the surface forces become dominant in comparison with the body forces. Because the magnitudes of the adhesive forces strongly depend on the surface interaction distances, which in turn evolve with the roughness of the contacting surfaces, the adhesive forces cannot be determined in a deterministic way. To quantify the uncertainties on the structural stiction behavior of a MEMS, this work proposes a “stochastic multi-scale methodology”. The key ingredient of the method is the evaluation of the random meso-scale apparent contact forces, which homogenize the effect of the nano-scale roughness and are integrated into a numerical model of the studied structure as a random contact law. To obtain the probabilistic behavior at the structural MEMS scale, a direct method needs to evaluate explicitly the meso-scale apparent contact forces in a concurrent way with the stochastic multi-scale approach. To reduce the computational cost, a stochastic model is constructed to generate the random meso-scale apparent contact forces. To this end, the apparent contact forces are parameterized by a vector of parameters before applying a polynomial chaos expansion in order to construct a mathematical model representing the probability of the random parameters vector. The problem of micro-beam stiction is then studied in a probabilistic way. [less ▲]

The transportation of goods is essential for the economy, but it also contributes to air pollution which, in turn, affects human health. These negative impacts generate additional costs for society that are not necessarily taken into account in public transportation policies and in private transportation decisions of companies and individuals. This leads to inefficient transportation systems where the social equilibrium is not reached. Intermodal transport is promoted by the European Commission to reduce these negative externalities. The objective of this paper is to analyze at a strategic level the effect on modal split between road, intermodal rail and intermodal inland waterway transport of several economic or environmental policies. An intermodal allocation model is applied to the Belgian case in order to identify the modal split changes between the single minimization of costs (operational or health-related external) and the introduction of additional road taxes.

L’article propose une réflexion critique et clinique sur la notion de « personnalité antisociale », largement usitée dans le domaine de la nosographie des troubles mentaux et des pratiques « psy- » au sein du système de justice pénale. Notre réflexion débutera par une généalogie du vocable dans différentes versions de la classification psychiatrique, depuis les années cinquante jusqu’aujourd’hui, et plus particulièrement celle faisant autorité du Manuel statistique et diagnostique des troubles mentaux (DSM). L’absence de raisonnement sociologique dans l’usage d’une notion impliquant pourtant la référence au « social » sera discutée ainsi que ses évolutions historiques. Ensuite, la démonstration de l’antithèse que cette notion constitue pour une perspective psychopathologique digne de ce nom – dynamique, compréhensive et phénoménologique – sera développée en six arguments majeurs et plurivoques, tantôt empiriques et cliniques, tantôt théoriques.

Many significant intellectual developments have taken place in 20th century European social theories. Notably the first Frankfurt School and Bourdieu’s work have successfully shown how workers, social actors, etc. are alienated or dominated by capitalist social structures. But according to Habermas, neither perspective successfully allows for the possibility that people could contribute to their own emancipation. The emergence of new forms of social resistance to domination such as those embodied by the Indignados, Anonymous, Femen, the practitioners of alternative economy, movements of unemployed people or illegals compels us to envisage the possibility for emancipation, but how? In this paper we explore opportunities for accounting for this by considering the work of a range of other European social theorists, more specifically Boltanski whose critical intent is embodied in his pragmatic sociology, and evident in his coining and use of the concept of the world. In addition we will consider Latour’s own pragmatic stance as we believe that despite his disinterest in new social movements, his work, informed by pure immanence, might offer potential solutions. But we would argue that even in these innovations there is either a persistent tendency to imagine emancipation primarily as a return to some ideal state or a lack of critical engagement with alienation. In response, we propose a materialist renewal, which will lead us to ponder on the political role of sociologists. [less ▲]

From Marx to Althusser, the materialist approach has tended to assume that individuals (that is, workers, proletarians and other social actors), unconsciously reproduce the social structures of capitalism which alienate them. It is assumed that individuals accept the conditions forced upon them and no longer seek to rebel against a world which substantially impoverishes their labour, their spirit and their creativity. In this paper, I will try to show that by dint of favouring almost exclusively Marx's concept of alienation, there is a considerable risk that materialist thought will adopt only a negative path. Whilst I acknowledge Marx’s significance to materialism, I wish to argue that his stance should be combined with that of the anarchist and libertarian French thinker Proudhon. Proudhon has succeeded in presenting a conception of the worker as more than just alienated. Workers can also cooperate and experience a reciprocity seemingly at odds with the character of capitalism. Under Proudhon’s influence materialism takes a positive turn, enabling us to avoid falling into the utopianism that the theory of social economy employs to critique capitalism – a utopianism that renders its critique even less effective than that of Marx.

Among physiological processes, the maintenance of immunity is one of the most energetically costly in invertebrates. Disease resistance can be quantified by measuring immunocompetence, which is defined as the ability of an organism to mount an immune response, either in cellular, humoral or behavioural forms. In insects, immune capacity can be affected by a variety of factors including pesticides, genetic diversity or diet. Here we focus on an important species of domesticated pollinator, Bombus terrestris, and the potential impact of a poor pollen diet (low nutritional content and toxic) on its health. We investigate three responses at both colony and individual levels: behavioural, humoral and cellular. Our results show that poor pollen diets decrease larval and pupal masses and increase larval ejection as well as adult constitutive immunity (i.e., prophenoloxidase assays). The susceptibility of bumblebees to disease and infection might therefore be greater after a nutritive stress. These findings raise the importance of available plant hosts, especially floral plant species providing pollen with suitable nutritive quality (i.e., nutrient pollen content) for bumblebees. © 2016 Elsevier Ltd [less ▲]

Teen dating is a developmental stage questioning dramatically the relationships to be expected with others, especially when feelings of tenderness and love are involved. It mobilizes parental attachment and the internal working models related to it, while being colored by the emerging romantic attachment and its brand new internal working models. Attachments are deeply shaped by a dynamic interaction whereby the self tries to figure out how to reach security and autonomy still taking the other into account. This considered, intimacy also implies a dynamic feature: on the one hand, closeness and sharing of feelings and/or experiences, and on the other hand, individuality and maintaining of one’s ego. However, just like attachments may be insecure, a fear of intimacy cannot be underestimated during dating. Eventually, bearing in mind the societal and cultural components of attachment and intimacy, gendered explanations cannot be ignored, especially during adolescence. Objectives: Three hypotheses are being tested. First, the continuity from parental to romantic attachment is postulated, meaning that a secure, preoccupied or dismissing attachment to parents might lead to a subsequent secure, preoccupied or dismissing attachment to romantic partners. Second, the influence of parental attachment on the fear of intimacy during teen dating is questioned. The difficult dynamic of closeness/individuality might be explained by the parental attachment’s patterns. Third, the impact of romantic attachment on the fear of intimacy during teen dating is assessed. Also, dating characteristics such as number of love relationships, age of the first dating experience and the longest lasting relationship are studied and put in perspective with the romantic attachment. Materials and methods: The initial sample is made of 283 Belgian students (61% girls) from different teaching systems, aged of 16-22 years old (mean age : 17.43), and 232 of them had already had a dating experience by this time. They were questioned about dating characteristics such as number of love relationships, age of the first dating experience and the longest lasting relationship. Two questionnaires were also self-administered: the Behavioral Systems Questionnaire (assessing attachment) and the Fear of Intimacy Scale. Statistical analyses such as Pearson Chi², Anova and Post-Hoc LSD were carried out. Results: First, we cannot see any continuity between parental and romantic attachment. Second, dismissing attachment to parents fosters the fear on intimacy, compared to secure profiles; this is especially true for dismissing girls. Third, dismissing and preoccupied attachments to romantic partners foster the fear of intimacy, compared to secure profiles; this is especially true for dismissing and even more for preoccupied boys. Also, preoccupied attachment to romantic partners fosters the multiplication of datings, compared to secure; this is especially true for preoccupied and even more for dismissing girls. Finally, there is no effect of romantic attachment on the age of the first dating experience or on the longest lasting relationship. Conclusion: Parental and romantic attachments are involved in the fear of intimacy experienced by adolescents during dating. Still, attachment styles’ influence seems different for girls and boys, and highlights the need to distinguish girls’ from boys’ teen dating experiences. [less ▲]
