Information technologies and communication between parents and children

This is an exploratory study that aims, on the one hand, to examine in more detail how children between 12 and 16 years of age use different audiovisual technologies, what they feel and think when using them, and whom they like to speak to about such experiences. On the other hand, we look more deeply into the interactions between adults and children, particularly between parents and their children, in relation to these technologies when children use them at home or in other places. We analysed responses to questionnaires with several common items, administered separately to parents and children. Children’s responses reflect an important level of dissatisfaction when talking with different adults about media activities. Our findings support the thesis that more and more children socialise through new information and communication technologies with little or no recourse to adult criteria, giving rise to the emergence of specific children’s cultures. Crossing of the responses of parents and those of their own children shows us which aspects of media reality adults overestimate or underestimate in comparison to children, and to what degree certain judgements coincide and differ between generations. The results can be applied to the improvement of relations between adults and adolescents, taking advantage of adolescents’ strong motivation to engage in activities using audiovisual media

Quels sont les facteurs de risque d'une bactériémie à Stenotrophomonas maltophilia chez les patients nonatteints de mucoviscidose ?

Problématique : Stenotrophomonas maltophilia est une bactérie Gram négatif présente dans¦l'environnement mais également responsable de nombreuses infections nosocomiales. Le but de cette¦étude a été de trouver quels étaient les facteurs de risques des patients non atteints de mucoviscidose¦ayant eu une bactériémie à S. maltophilia.¦Méthode : Il s'agit d'une étude cas-témoin. La population étudiée était les patients du CHUV de plus¦de 18 ans avec une ou plus paire(s) d'hémoculture positive pour S. maltophilia entre 2000-2010, en¦excluant tout patient atteint de mucoviscidose. Les variables binaires ont été analysées par le test de¦McNemar. Les variables continues ont été comparées avec le Wilcoxon Rank-Sum test. L'analyse¦multivariée des facteurs de risque indépendants a été effectuée par une régression logistique¦conditionnelle.¦Résultats : 46 épisodes d'hémocultures positives ont été identifiés. L'insuffisance rénale, une maladie¦oncologique et l'agranulocytose ont été identifiés comme des facteurs de risques significatifs.¦L'analyse multivariée a montré les facteurs suivants sont associés indépendamment à une bactériémie :¦1) l'agranulocytose (odds ratio, 7.0 ; 95% intervalle de confiance, 1.5 - 32.2 ; p= 0.012) 2) le cancer¦(odds ratio, 4.9 ; 95% intervalle de confiance, 1.7 - 14.2 ; p= 0.003) 3)l'insuffisance rénale (odds¦ratio, 5.2 ; 95% intervalle de confiance, 1.5 - 17.4 ; p= 0.008)¦Conclusions : L'insuffisance rénale, la maladie oncologique et l'agranulocytose sont des facteurs de¦risque indépendants pour une bactériémie à S. maltophilia. Les patients présentant ces critères de¦vulnérabilité doivent donc être particulièrement surveillés.

Définir le risque du carcinome spinocellulaire: rôle de la clinique et du rapport anatomopathologique [Risk of cutaneous squamous cell carcinomas: the role of clinical and pathological reports].

The history of most cutaneous squamous cell carcinomas (CSCC) is limited to the skin. However, about 4% of these malignancies are at risk of metastasis and can be life-threatening. This risk is determined by clinical and histological elements which are individually recognized, but so far staging systems allow us neither to assess a risk score, nor to adopt a standardized therapeutical approach. This article reviews prognostic factors for CSCC, and underlines the need for the clinician to have all clinical and histological elements available, in order to try to define the best therapeutical strategy for each case, following up-to-date recommendations.

Les groupes de parole de prévention de la récidive au sein des SPIP: une évolution centrée sur la gestion du risque, entre théorie et adaptation pratique

En France, les différentes réorientations pénales et les missions confiées au Service Pénitentiaire d'Insertion et de Probation (SPIP) placent l'évaluation des risques de récidive et leur prévention au centre de la pratique professionnelle des Conseillers Pénitentiaires d'Insertion et de Probation (CPIP). Les récentes évolutions législatives des missions des SPIP, les mutations identitaires et des pratiques qu'elles impliquent -en particulier les Groupes de Paroles de Prévention de la Récidive (GPPR)-, caractérisent une évolution centrée sur la gestion du risque. Partant de critiques dans la littérature sur la notion de gestion du risque de récidive dans les pratiques pénales et de ce qu'elle induit dans les modes d'appréhension des sujets et dans les interventions professionnelles, l'article met en relation les réorientations vers une gestion du risque telles qu'elles peuvent apparaître dans les textes, missions et référentiel du SPIP, avec une évaluation des pratiques professionnelles centrées sur les GPPR intégrés au sein des SPIP. Y a-t-il infiltration et remodelage des pratiques ? Si c'est bien le cas, on examine où se situe le niveau pertinent de cette influence et du réaménagement des pratiques.

Communication skills training in oncology: a position paper based on a consensus meeting among European experts in 2009.

BACKGROUND: Communication in cancer care has become a major topic of interest. Since there is evidence that ineffective communication affects both patients and oncology clinicians (physicians and nurses), so-called communication skills trainings (CSTs) have been developed over the last decade. While these trainings have been demonstrated to be effective, there is an important heterogeneity with regard to implementation and with regard to evidence of different aspects of CST. METHODS: In order to review and discuss the scientific literature on CST in oncology and to formulate recommendations, the Swiss Cancer League has organised a consensus meeting with European opinion leaders and experts in the field of CST, as well as oncology clinicians, representatives of oncology societies and patient organisations. On the basis of a systematic review and a meta-analysis, recommendations have been developed and agreed upon. RESULTS: Recommendations address (i) the setting, objectives and participants of CST, (ii) its content and pedagogic tools, (iii) organisational aspects, (iv) outcome and (v) future directions and research. CONCLUSION: This consensus meeting, on the basis of European expert opinions and a systematic review and meta-analysis, defines key elements for the current provision and future development and evaluation of CST in oncology.

Interplay of spectral efficiency, power and doppler spectrum for reference-signal-assisted wireless communication

Expressions relating spectral efficiency, power, and Doppler spectrum, are derived for Rayleigh-faded wireless channels with Gaussian signal transmission. No side information on the state of the channel is assumed at the receiver. Rather, periodic reference signals are postulated in accordance with the functioning of most wireless systems. The analysis relies on a well-established lower bound, generally tight and asymptotically exact at low SNR. In contrast with most previous studies, which relied on block-fading channel models, a continuous-fading model is adopted. This embeds the Doppler spectrum directly in the derived expressions, imbuing them with practical significance. Closed-form relationships are obtained for the popular Clarke-Jakes spectrum and informative expansions, valid for arbitrary spectra, are found for the low- and high-power regimes. While the paper focuses on scalar channels, the extension to multiantenna settings is also discussed.

High-SNR power offset in multiantenna communication

The analysis of the multiantenna capacity in the high-SNR regime has hitherto focused on the high-SNR slope (or maximum multiplexing gain), which quantifies the multiplicative increase as function of the number of antennas. This traditional characterization is unable to assess the impact of prominent channel features since, for a majority of channels, the slope equals the minimum of the number of transmit and receive antennas. Furthermore, a characterization based solely on the slope captures only the scaling but it has no notion of the power required for a certain capacity. This paper advocates a more refined characterization whereby, as function of SNRjdB, the high-SNR capacity is expanded as an affine function where the impact of channel features such as antenna correlation, unfaded components, etc, resides in the zero-order term or power offset. The power offset, for which we find insightful closed-form expressions, is shown to play a chief role for SNR levels of practical interest.

Young infants' triangular communication with their parents in the context of maternal postpartum psychosis: Four case studies

With increasing data on the dynamics of normative couples as they transition to parenthood and become a triad, the need for greater understanding of the impact of parental psychopathology on this transition has become clear. The goal of the current article is to begin exploring this area that has received little attention to date, by describing case examples from a study of clinical families as they transitioned to parenthood. Four representative cases were selected from a pool of 13 mother-father-baby triads, for whom the mother had been hospitalized conjointly with her infant due to a psychotic episode during the postpartum period. The families were observed as part of a clinical consultation that included a semistructured play paradigm known as the Lausanne Trilogue Play (LTP; E. Fivaz-Depeursinge, & A. Corboz-Warnery, 1999). Interactions were scored using standardized measures as well as clinical impressions. All families from the clinical sample were noted to struggle and frequently failed to achieve the goals of play. The impact on the infants in terms of their developing sense of self as well as their defensive strategies in this context are discussed, with clinical implications explored.
