It could be misleading to consider that the social behaviour of newts and salamanders is simple and can be generalized. Indeed, individuals are faced with external and internal conditions which are extremely variable. In response to these factors, they may respond in a particular way. The behavioural variations, called alternative tactics, allow individuals to improve their fitness, i.e. to ensure the survival of their genes. They can be exhibited in reaction to a large range of factors such as the mere presence or density of competitors, the operational sex-ratio, the behaviour and kinship of the other individuals, the abiotic characteristics of the environment, the experience of the individuals involved. These alternative tactics are favoured in urodeles. Indeed, although the main process of fertilization is internal, they breed by means of a spermatophore deposited in the external environment. Each species of newts and salamanders exhibits specific behavioural patterns as they developed and evolved in particular environments which have exerted selective pressures on the individuals and in this way on the species. As a consequence, the understanding of patterns of behaviour requires that we know the environment in which they appeared. The main occurrence of parental care and territoriality in terrestrial environments may be explained by the features of these habitats in which eggs could not survive without protection, and in which adults may defend areas of particular interest and communicate by means of pheromones. All of these characteristics show that we have to study the behaviour of individuals of different species under several conditions. Without such an analysis, it would be difficult to understand biodiversity. [less ▲]

La pédagogie basée sur la théorie des "rythmes d'apprentissage" accorde une place privilégiée à l'individualisation et contredit le principe d'une programmation uniforme, valable pour tous. Toute classe est hétérogène, chaque enfant étant singulier, différent dans ses valeurs, ses attitudes, ses potentialités et ses compétences. Chacun apprend à un rythme différent, plus rapidement que la moyenne dans des domaines, moins rapidement dans d'autres. ... [less ▲]

Les données présentées dans cet article confirment de manière assez forte celles de la littérature. Les performances des sujets dysphasiques (EDP) francophones étudiés sont, d'une part, inférieures à celles d'enfants contrôles appariés sur la base de l'âge chronologique (EDL) et, d'autre part, inférieures en production par rapport à la compréhension. Les aspects morphologiques du langage posent des difficultés particulières aux EDP. Les erreurs effectuées par les EDP sont différentes de celles des enfants EDL. Le profil des EDP est tout à fait particulier et ne se superpose que sommairement à celui des EDL. De ce point de vue, nous pouvons parler de déviance. [less ▲]

Composantes psychologiques des plaintes relatives à la taille du pénis après implantation d'une prothèse pénienne

A survey questionnaire completed by 39 users of penile prosthesis shows that complaints related to the size of the implanted penis involve a decrease in satisfaction towards the prosthetic device. However, a reduced penile size is not necessary considered as a problem by all patients. Beyond functional considerations, the disappointment concerning the length of the penis is mostly related to the representation of a virility debased by the notions of artifice and assistance which are associated to the penile implant. Strong correlations are actually reported between a lower satisfaction, complaints related to the length of the implanted penis, feelings of shame, a lower self-esteem due to the idea of an "artificial virility" and a trend to attribute a negative attitude towards penile implant to the partner. On the whole, these variables appear to be the expression of a global castration experience that makes the psychosexual assimilation of the prosthesis rather precarious. This castration experience is derived from a certain representation of male erotic quality which requires long, natural and spontaneous erections. From this point of view, the injurious impact of reduced erections seems inseparable from an injurious representation of prosthetic sexuality globally perceived as a “parodic”, “reduced” virility. It is remarkable that none of these variables correlates with the partners' actual opinions concerning prosthesis and sexuality permitted by penile implant. Parallel questionnaires completed separately by 27 partners show that part of the men's injurious representation partakes of projective mechanisms. Such observations underline the relevance of a psychosexological approach of the couple in addition of the surgical approach. [less ▲]
