Immigration and the school system

Immigration is an important problem in many societies, and it has wide-ranging effects on the educational systems of host countries. There is a now a large empirical literature, but very little theoretical work on this topic. We introduce a model of family immigration in a framework where school quality and student outcomes are determined endogenously. This allows us to explain the selection of immigrants in terms of parental motivation and the policies which favor a positive selection. Also, we can study the effect of immigration on the school system and how school quality may self-reinforce immigrants' and natives' choices.

More is not always better-comparison of three instruments measuring volume of drinking in a sample of young men and their association with consequences

OBJECTIVE: In general population survey instruments that measure volume of drinking, additional questions and shorter reference periods yield higher volumes. Comparison studies have focused on volume but not on associations between volume and consequences. METHOD: From a cohort study on substance use risk factors (Cohort Study on Substance Use Risk Factors [C-SURF]), baseline data were analyzed for 5,074 young (approximately 20-year-old) men who were drinkers in the past 12 months. Volume of drinking was measured by a generic quantity-frequency (QF) instrument, an extended QF (separately for weekends and weekdays) instrument with 12-months recall, and a retrospective past-week diary. Associations of consequences with and without attribution of alcohol as a cause, Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), criteria for dependence, and DSM-5 alcohol use disorder in the past 12 months were analyzed. RESULTS: The generic QF measure resulted in lower volume compared with either the extended QF measure (more questions) or the retrospective diary (the most questions and the shortest recall period). For outcomes, however, the extended QF assessment performed the best and the diary the worst. CONCLUSIONS: Higher volume yields are not always better regarding associations with outcomes. The extended QF instrument better captures the variability of drinking. The retrospective diary performs poorly for associations because of the mismatch with the recall period for past-12-months consequences and the potential for misclassification of past-week abstainers and heavy drinkers because of an uncommon past week. Diaries are not recommended for research investigating individual associations between exposure and outcomes in young populations if consequences are measured with a sufficiently long interval to capture rare consequences.

Depression with atypical features and increase in obesity, body mass index, waist circumference, and fat mass: a prospective, population-based study.

IMPORTANCE: Depression and obesity are 2 prevalent disorders that have been repeatedly shown to be associated. However, the mechanisms and temporal sequence underlying this association are poorly understood. OBJECTIVE: To determine whether the subtypes of major depressive disorder (MDD; melancholic, atypical, combined, or unspecified) are predictive of adiposity in terms of the incidence of obesity and changes in body mass index (calculated as weight in kilograms divided by height in meters squared), waist circumference, and fat mass. DESIGN, SETTING, AND PARTICIPANTS: This prospective population-based cohort study, CoLaus (Cohorte Lausannoise)/PsyCoLaus (Psychiatric arm of the CoLaus Study), with 5.5 years of follow-up included 3054 randomly selected residents (mean age, 49.7 years; 53.1% were women) of the city of Lausanne, Switzerland (according to the civil register), aged 35 to 66 years in 2003, who accepted the physical and psychiatric baseline and physical follow-up evaluations. EXPOSURES: Depression subtypes according to the DSM-IV. Diagnostic criteria at baseline and follow-up, as well as sociodemographic characteristics, lifestyle (alcohol and tobacco use and physical activity), and medication, were elicited using the semistructured Diagnostic Interview for Genetic Studies. MAIN OUTCOMES AND MEASURES: Changes in body mass index, waist circumference, and fat mass during the follow-up period, in percentage of the baseline value, and the incidence of obesity during the follow-up period among nonobese participants at baseline. Weight, height, waist circumference, and body fat (bioimpedance) were measured at baseline and follow-up by trained field interviewers. RESULTS: Only participants with the atypical subtype of MDD at baseline revealed a higher increase in adiposity during follow-up than participants without MDD. The associations between this MDD subtype and body mass index (β = 3.19; 95% CI, 1.50-4.88), incidence of obesity (odds ratio, 3.75; 95% CI, 1.24-11.35), waist circumference in both sexes (β = 2.44; 95% CI, 0.21-4.66), and fat mass in men (β = 16.36; 95% CI, 4.81-27.92) remained significant after adjustments for a wide range of possible cofounding. CONCLUSIONS AND RELEVANCE: The atypical subtype of MDD is a strong predictor of obesity. This emphasizes the need to identify individuals with this subtype of MDD in both clinical and research settings. Therapeutic measures to diminish the consequences of increased appetite during depressive episodes with atypical features are advocated.

Identification of CARDIAK, a RIP-like kinase that associates with caspase-1.

Members of the tumor necrosis factor receptor (TNFR) superfamily have an important role in the induction of cellular signals resulting in cell growth, differentiation and death. TNFR-1 recruits and assembles a signaling complex containing a number of death domain (DD)-containing proteins, including the adaptor protein TRADD and the serine/threonine kinase RIP, which mediates TNF-induced NF-kappa B activation. RIP also recruits caspase-2 to the TNFR-1 signaling complex via the adaptor protein RAIDD, which contains a DD and a caspase-recruiting domain (CARD). Here, we have identified a RIP-like kinase, termed CARDIAK (for CARD-containing interleukin (IL)-1 beta converting enzyme (ICE) associated kinase), which contains a serine/threonine kinase domain and a carboxy-terminal CARD. Overexpression of CARDIAK induced the activation of both NF-kappa B and Jun N-terminal kinase (JNK). CARDIAK interacted with the TNFR-associated factors TRAF-1 and TRAF-2, and a dominant-negative form of TRAF-2 inhibited CARDIAK-induced NF-kappa B activation. Interestingly, CARDIAK specifically interacted with the CARD of caspase-1 (previously known as ICE), and this interaction correlated with the processing of pro-caspase-1 and the formation of the active p20 subunit of caspase-1. Together, these data suggest that CARDIAK may be involved in NF-kappa B/JNK signaling and in the generation of the proinflammatory cytokine IL-1 beta through activation of caspase-1.

Assessment of Physical Activity and Energy Expenditure by GPS Combined With Accelerometry in Real-Life Conditions.

Background: Physical activity (PA) and related energy expenditure (EE) is often assessed by means of a single technique. Because of inherent limitations, single techniques may not allow for an accurate assessment both PA and related EE. The aim of this study was to develop a model to accurately assess common PA types and durations and thus EE in free-living conditions, combining data from global positioning system (GPS) and 2 accelerometers. Methods: Forty-one volunteers participated in the study. First, a model was developed and adjusted to measured EE with a first group of subjects (Protocol I, n = 12) who performed 6 structured and supervised PA. Then, the model was validated over 2 experimental phases with 2 groups (n = 12 and n = 17) performing scheduled (Protocol I) and spontaneous common activities in real-life condition (Protocol II). Predicted EE was compared with actual EE as measured by portable indirect calorimetry. Results: In protocol I, performed PA types could be recognized with little error. The duration of each PA type could be predicted with an accuracy below 1 minute. Measured and predicted EE were strongly associated (r = .97, P < .001). Conclusion: Combining GPS and 2 accelerometers allows for an accurate assessment of PA and EE in free-living situations.

Retest reliability of individual p3 topography assessed by high density electroencephalography.

BACKGROUND Some controversy remains about the potential applicability of cognitive potentials for evaluating the cerebral activity associated with cognitive capacity. A fundamental requirement is that these neurophysiological parameters show a high level of stability over time. Previous studies have shown that the reliability of diverse parameters of the P3 component (latency and amplitude) ranges between moderate and high. However, few studies have paid attention to the retest reliability of the P3 topography in groups or individuals. Considering that changes in P3 topography have been related to different pathologies and healthy aging, the main objective of this article was to evaluate in a longitudinal study (two sessions) the reliability of P3 topography in a group and at the individual level. RESULTS The correlation between sessions for P3 topography in the grand average of groups was high (r = 0.977, p<0.001). The within-subject correlation values ranged from 0.626 to 0.981 (mean: 0.888). In the between-subjects topography comparisons, the correlation was always lower for comparisons between different subjects than for within-subjects correlations in the first session but not in the second session. CONCLUSIONS The present study shows that P3 topography is highly reliable for group analysis (comprising the same subjects) in different sessions. The results also confirmed that retest reliability for individual P3 maps is suitable for follow-up studies for a particular subject. Moreover, P3 topography appears to be a specific marker considering that the between-subjects correlations were lower than the within-subject correlations. However, P3 topography appears more similar between subjects in the second session, demonstrating that is modulated by experience. Possible clinical applications of all these results are discussed.

Epidémiologie des cancers épithéliaux de la peau [Epidemiology of epithelial skin cancers]

With no less than 15,000 estimated new cases diagnosed per year, non melanomatous carcinomas are the commonest cutaneous cancers in the Swiss population. About 1 in 3 new cancer case is a basal (BCC) or a squamous cell carcinoma (SCC). Incidence rates are steadily increasing, faster for BCC than SCC. Rates are higher for men than women and increase exponentially with age. Systematic population-based registration of non melanomatous skin cancers faces many challenges that few cancer registries can meet. Rates of these cancers in Switzerland are among the highest in Europe. Primary and secondary nationwide prevention campaigns have been carried out for nearly 20 years with a focus on the deadliest cutaneous cancer: melanoma. However, detection of non melanomatous skin cancers benefits from these campaigns since prevention messages and means of early detection are similar for melanomas and other skin cancers.

Le couvent de Romainmôtier du début de l'époque clunisienne à la fin du XIIe siècle : étude archivistique, diplomatique et historique, suivie de l'édition du chatrier

Les chartes de l'ancien couvent de Romainmôtier constituent une source d'information essentielle pour l'histoire du Pays de Vaud aux Xe et XIe siècles. Toutefois, malgré leur importance, elles n'ont jamais fait l'objet d'une étude d'ensemble. Les historiens dépendent encore aujourd'hui de transcriptions partielles et fautives, imprimées au XIXe siècle. Afin de remédier à cette carence historiographique, Alexandre Pahud, qui a réuni l'ensemble des documents entre 888 et 1190, propose dans sa thèse de doctorat, soutenue à l'Université de Lausanne le 25 novembre 2008, une édition critique de tous ces textes, selon les principes de l'érudition moderne. Si les Archives cantonales vaudoises conservent la majeure partie de la documentation, d'autres institutions en Suisse et à l'étranger fournissent un apport substantiel concernant Romainmôtier avant le XIIIe siècle. Il s'agit en particulier des Archives de l'Etat de Fribourg, des Archives de l'Etat de Berne et de la Bibliothèque royale de Turin. En raison d'une importante dispersion des fonds, A. Pahud a entrepris de reconstituer le chartrier du couvent, tel qu'il devait exister à l'époque médiévale. Pour cela, il s'est basé sur les notes dorsales qui figurent au verso des parchemins, ainsi que sur les anciens inventaires. La méthode utilisée a permis de retrouver plusieurs chartes du début de l'an mil, sous la forme de copies intégrales, ainsi qu'une vingtaine de notices en allemand résumant des actes des Xe-XIIe siècles, tous ces textes étant demeurés inconnus des spécialistes. Ainsi, la thèse de A. Pahud démontre qu'il est possible d'apporter de nouveaux matériaux destinés à enrichir notre connaissance de cette période reculée et mal documentée au niveau local. En parallèle, l'auteur de la thèse a mené une expertise diplomatique des chartes de Romainmôtier, c'est-à-dire une étude de leurs caractéristiques matérielles et formelles. A l'examen, il apparaît que les moines ont davantage acquis de biens qu'ils n'en ont concédé à des tiers, symptôme d'un patrimoine en voie de formation. Les actes privés, qui relatent des transactions entre le monastère et ses voisins, représentent le 80% du corpus étudié. Ils sont rédigés tantôt au présent et à la première personne, tantôt au passé et à la troisième personne, lorsqu'ils ne mélangent pas les deux types de discours. Leur valeur juridique est assurée par une liste de témoins, à défaut de tout scellement. Dans la majorité des cas, un unique scribe établit son texte en une seule fois, après la cérémonie sanctionnant le transfert de propriété. Jusqu'en 1050, ce sont généralement des personnes extérieures à Romainmôtier qui instrumentent au profit du couvent; par la suite, les clunisiens reprennent à leur compte la confection des actes qui les concernent. Curieusement, on constate une disparition radicale de l'acte privé à Romainmôtier entre 1167 et 1198, phénomène qui tranche complètement sur la conjoncture régionale. Dans la dernière partie de sa thèse, A. Pahud présente une nouvelle histoire du couvent de Romainmôtier, qui aborde à la fois les questions politiques et les structures socioéconomiques. Durant le premier tiers du XIe siècle, les clunisiens de Romainmôtier bénéficient de la protection du dernier roi de Bourgogne, Rodolphe III (993-1032), qui fonde la puissance temporelle du monastère. A cette époque, l'institution est administrée directement par l'abbé de Cluny, Odilon, responsable de Romainmôtier à titre personnel. Cependant, la disparition de Rodolphe III, dont la succession est contestée, inaugure une période de grave insécurité dans nos régions. Ces troubles profitent avant tout aux seigneurs locaux, qui prennent appui sur un château pour imposer leur domination au détriment des pouvoirs ecclésiastiques. Au milieu du XIe siècle, les possessions de Romainmôtier, qui s'étendent de chaque côté du Jura, sont menacées par trois puissants lignages, les Grandson, les Salins et les Joux. Face à cette situation périlleuse, les religieux s'adressent tour à tour au pape, à l'empereur germanique, ainsi qu'aux comtes de Bourgogne, dépositaires d'une autorité publique en Franche-Comté. Mais bien souvent, les moines doivent transiger avec leurs adversaires, en passant avec eux des accords coûteux et fragiles. Cela n'empêche pas qu'une certaine coopération s'établisse à l'occasion avec le monde laïque, qui contribue par ses aumônes au développement économique du monastère. Romainmôtier tire ses principales ressources de l'agriculture, tant au Pays de Vaud qu'en Franche-Comté; le travail de la vigne est bien attesté sur La Côte, dès la fin du Xe siècle, tandis que l'élevage ne joue qu'un rôle secondaire; là où ils sont bien implantés, les moines parviennent à prendre le contrôle des moulins; à Salins (France), ils exploitent eux-mêmes le sel nécessaire à leurs besoins. L'ensemble de ces observations s'appuie sur des tableaux et des annexes, qui ajoutent à la critique interne des sources une dimension quantitative. Afin de divulguer les résultats obtenus, A. Pahud envisage de publier prochainement sa thèse dans les Mémoires et documents de la Société d'histoire de la Suisse romande.
