We present tree community diversity, species composition, basal area and aboveground biomass of three forest types in the Dja Biosphere Reserve, in South-East Cameroon, part of the contiguous tropical forest of the Congo Basin. A total of fourteen, 1 ha, plots were established in heterogeneous terra firme forests (TFF), Gilbertiodendron dewevrei forests (GDF) and periodically flooded forests (PFF). A total of 281 tree species with diameter ‡10 cm were recorded. The Shannon diversity index was significantly higher in TFF (5.7 ± 0.28) and PFF (5.6 ± 0.23) than in GDF (2.29 ± 0.48) (ANOVA, F2,11 = 139.75, P < 0.001). While tree density did not differ between forest types (F2,11 = 3.50, P = 0.06), basal area differed significantly (F2,11 = 7.38, P = 0.009), as did aboveground biomass (F2,11 = 17.95, P < 0.001). Mean AGB values were respectively, 596.1 ± 62.24, 401.67 ± 58.06 and 383.14 ± 61.91 Mg ha)1 in GDF, TFF and PFF. Variation in the abundance of trees with large diameter was the main reason for these differences. Few dominant species made the greatest contribution to the AGB. G. dewevrei, accounted for 83% of AGB in GDF, Penthaclethra macrophylla for 9.9% in TFF and Uapaca heudolotii for 10.6% in PFF. The importance of preserving G. dewevrei forest in the context of ‘Reducing Emissions from Deforestation and forest Degradation’ (REDD) policies is discussed. [less ▲]

A finite-volume method has been developed that can deal accurately with complicated, curved boundaries for both two-dimensional and three-dimensional axisymmetric advection-diffusion systems. The motivation behind this is threefold. Firstly, the ability to model the correct geometry of a situation yields more accurate results. Secondly, smooth geometries eliminate corner singularities in the calculation of, for example, mechanical variables and thirdly, different geometries can be tested for experimental applications. An example illustrating each of these is given: fluid carrying a dye and rotating in an annulus, bone fracture healing in mice, and using vessels of different geometry in an ultracentrifuge.

Among the numerous changes which the notion of family has known over time, we are interested here in the normalization/acceptability of the divorce (or separation). We postulate that, in a context where these modifications are less and less ritualized and thus, less and less representable, the family (whose achronic character we shall differentiate from the diachronic) has no access to a social representability/acceptability of its separations. According to us, the family suffers then from an identity crisis of which the child, sometimes on top of his individual sufferings, can be the symptom. Then it remains for the therapists to make up for this lack of representability of separations, while remaining lucid about the limits of their interventions. [less ▲]

In examining relationships between autopoiesis and anticipation in artificial life (Alife) systems it is demonstrated that anticipation may increase efficiency and viability in artificial autopoietic living systems. This paper, firstly, gives a review of the Varela et al [1974] automata algorithm of an autopoietic living cell. Some problems in this algorithm must be corrected. Secondly, a new and original anticipatory artificial autopoiesis algorithm for automata is presented. In our automata system, the asymmetric membrane of the self-creating living cell plays a central role. The simulation confirms the validity of our algorithm in showing its autopoietic properties.

Birds are anosmic or at best microsmatic... This misbelief persisted until very recently and has strongly influenced the outcome of communication studies in birds, with olfaction remaining neglected as compared to acoustic and visual channels. However, there is now clear empirical evidence showing that olfaction is perfectly functional in birds and birds use olfactory information in a variety of ethological contexts. Although the existence of pheromones has never been formally demonstrated in this vertebrate class, different groups of birds, such as petrels, auklets and ducks have been shown to produce specific scents that could play a significant role in within-species social interactions. Behavioral experiments have indeed demonstrated that these odors influence the behavior of conspecifics. Additionally, in quail, deprivation of olfactory inputs decreases neuronal activation induced by sexual interactions with a female. It seems therefore well established that birds enjoy a functional sense of smell and a fast growing body of experimental evidence suggests that they use this channel of olfactory communication to control their social life. The unequivocal identification of an avian pheromone is, however, still ahead of us but there are now many exciting opportunities to unravel the behavioral and physiological particularities of chemical communication in birds.

Context: AIP mutations (AIPmut) give rise to a pituitary adenoma predisposition that occurs in familial isolated pituitary adenomas and less often in sporadic cases. The clinical and therapeutic features of AIPmut-associated pituitary adenomas have not been studied comprehensively. <br />Objective: The objective of the study was to assess clinical/therapeutic characteristics of AIPmut pituitary adenomas. <br />Design: This study was an international, multicenter, retrospective case collection/database analysis. <br />Setting: The study was conducted at 36 tertiary referral endocrine and clinical genetics departments. <br />Patients: Patients included 96 patients with germline AIPmut and pituitary adenomas and 232 matched AIPmut-negative acromegaly controls. <br />Results: The AIPmut population was predominantly young and male (63.5%); first symptoms occurred as children/adolescents in 50%. At diagnosis, most tumors were macroadenomas (93.3%); extension and invasion was common. Somatotropinomas comprised 78.1% of the cohort; there were also prolactinomas (n = 13), nonsecreting adenomas (n = 7), and a TSH-secreting adenoma. AIPmut somatotropinomas were larger (P = 0.00026), with higher GH levels (P = 0.00068), more frequent extension (P = 0.018) and prolactin cosecretion (P = 0.00023), and occurred 2 decades before controls (P < 0.000001). Gigantism was more common in the AIPmut group (P < 0.000001). AIPmut somatotropinoma patients underwent more surgical interventions (P = 0.00069) and had lower decreases in GH (P = 0.00037) and IGF-I (P = 0.028) and less tumor shrinkage with somatostatin analogs (P < 0.00001) vs. controls. AIPmut prolactinomas occurred generally in young males and frequently required surgery or radiotherapy. <br />Conclusions: AIPmut pituitary adenomas have clinical features that may negatively impact treatment efficacy. Predisposition for aggressive disease in young patients, often in a familial setting, suggests that earlier diagnosis of AIPmut pituitary adenomas may have clinical utility. [less ▲]

Faced with new challenge from globalization, technological and demographic changes, today organizational training takes a crucial importance in the development of human resources in organizations. From both a scientific and practical point of view, two major currents presently seem to rule this field: a psychosociological current and an ergonomic current. The contributions of each of them in organizational human resources development are unquestionable, but we have observed significant levels of misunderstanding between the two, as well as a lack of dialogue and scientific objectivity. The present paper intends to initiate this dialogue with an eye towards developing training practices. Thanks to a better understanding of these main approaches, our aim is to help those who seek to train personnel to better orientate their choice of training. From this perspective, based as much on historical research as on more recent works, several common points are obvious. (1) There is a wish to develop new learning strategies which draws substance from scientific research, and which breaks with school-based models. (2) There is a strong link between theory and action, together with practices that combine doing and knowledge. (3) There is also a vision of learning as the result of action combined with reflection on action. In contrast with these shared foundations, several differences leading to fruitful exchange have been identified. (1) Focus on group from psychosociological approaches, as opposed to focus on work from ergonomic perspectives; (2) concentration on functional and specific aspects of work in the ergonomic approach and emphasis on relational and transversal aspects in the psychosociological approach; (3) four points on which technical exchanges would be profitable; (4) a major controversy on the question of whether the link between work and training is necessary or not. By becoming aware of the complementarity of the two approaches (compatible and different), we become convinced that it is essential to begin a dialogue in order to make organizational training practices more understandable and more effective.
