Biased V beta usage in immature thymocytes is independent of DJ beta proximity and pT alpha pairing.

During thymus development, the TCR beta locus rearranges before the TCR alpha locus. Pairing of productively rearranged TCR beta-chains with an invariant pT alpha chain leads to the formation of a pre-TCR and subsequent expansion of immature pre-T cells. Essentially nothing is known about the TCR V beta repertoire in pre-T cells before or after the expression of a pre-TCR. Using intracellular staining, we show here that the TCR V beta repertoire is significantly biased at the earliest developmental stage in which VDJ beta rearrangement has occurred. Moreover (and in contrast to the V(H) repertoire in immature B cells), V beta repertoire biases in immature T cells do not reflect proximity of V beta gene segments to the DJ beta cluster, nor do they depend upon preferential V beta pairing with the pT alpha chain. We conclude that V gene repertoires in developing T and B cells are controlled by partially distinct mechanisms.

The role of the object and the mourning process in the child

The young child's ability to go through a genuine mourning process has been a source of controversy in the psychoanalytical literature. This may seem surprising, considering that mourning is essential for and inherent to psychic development. This paper attempts to show that the young child's ability to go through a mourning process does not depend mainly on ego maturity, nor just on an acknowledgment of a loss in the external world, nor on the child's understanding the idea of death at an intellectual and cognitive level. But it may depend mainly on the establishment of the primordial mourning process inherent to the separation of the transnarcissistic mother-child relation and on the existence of the objectalizing function (A. Green, 1986) in the remaining or substitute parent's psyche. A clinical example serves to illustrate these hypotheses.

Parent-child agreement and prevalence estimates of diagnoses in childhood: direct interview versus family history method.

Diagnostic information on children is typically elicited from both children and their parents. The aims of the present paper were to: (1) compare prevalence estimates according to maternal reports, paternal reports and direct interviews of children [major depressive disorder (MDD), anxiety and attention-deficit and disruptive behavioural disorders]; (2) assess mother-child, father-child and inter-parental agreement for these disorders; (3) determine the association between several child, parent and familial characteristics and the degree of diagnostic agreement or the likelihood of parental reporting; (4) determine the predictive validity of diagnostic information provided by parents and children. Analyses were based on 235 mother-offspring, 189 father-offspring and 128 mother-father pairs. Diagnostic assessment included the Kiddie-schedule for Affective Disorders and Schizophrenia (K-SADS) (offspring) and the Diagnostic Interview for Genetic Studies (DIGS) (parents and offspring at follow-up) interviews. Parental reports were collected using the Family History - Research Diagnostic Criteria (FH-RDC). Analyses revealed: (1) prevalence estimates for internalizing disorders were generally lower according to parental information than according to the K-SADS; (2) mother-child and father-child agreement was poor and within similar ranges; (3) parents with a history of MDD or attention deficit hyperactivity disorder (ADHD) reported these disorders in their children more frequently; (4) in a sub-sample followed-up into adulthood, diagnoses of MDD, separation anxiety and conduct disorder at baseline concurred with the corresponding lifetime diagnosis at age 19 according to the child rather than according to the parents. In conclusion, our findings support large discrepancies of diagnostic information provided by parents and children with generally lower reporting of internalizing disorders by parents, and differential reporting of depression and ADHD by parental disease status. Follow-up data also supports the validity of information provided by adolescent offspring.

Nominal plural marking of nonce words in child Spanish

This study addresses the issue of Spanish plural marking considering data from three sources: existent words, loan words and nonce words. Specifically, we are interested in the role of stress placement and word-final sound in the use of /-es/ for plural formation. We present data concerning the interaction of these two features for children and adults. Our findings suggest that this phenomenon is a classic example of over generalization in acquisition. Stress does not seem a determining feature by itself. Its main effect is produced when it interacts with the structure of the syllable

IPH response to RICHE questionnaire on child health research in Europe

Request to participate in an expert group review of child health research gaps and priorities in Ireland and Northern Ireland IPH responded to a questionnaire from the FP7 funded project - RICHE ( www.childhealthresearch.eu). The project goal is to produce an inventory of child health research in Europe, identify gaps in existing and on-going research, and devise a series of roadmaps for the future of child health research. This is co-ordinated by Anthony Staines from DCU, and Michael Rigby, from the Nordic School. This specific phase of the project is being co-ordinated by Matilde Leonardi and Giorgio Tamburlini in Italy.

Dynamique réflexive et transférabilité des compétences : un usage intégré du e-Portfolio en spécialisation

Dernière étape avant le monde professionnel, un cursus de spécialisation est un lieu de discussion, au carrefour des savoirs et des savoir-faire, permettant aux étudiants d'envisager sous un angle nouveau les contenus enseignés à l'université. Il ne s'agit plus seulement d'acquérir des connaissances mais aussi de développer des compétences transférables à d'autres types d'activité. L'équipe en charge de la spécialisation en Analyse du discours et de la communication publics proposée par la Faculté des Lettres de l'Université de Lausanne a oeuvré à l'intégration d'un nouvel outil informatique, le e-Portfolio, destiné à faciliter l'expression et la documentation des compétences individuelles développées par l'étudiant lors de son parcours de formation.
