Immature stages of mosquitoes (Diptera: Culicidae) Collected during the autumn-winter period in Cordoba Province, Argentina

Eggs, immature mosquito collections were made at Cosquin, La Calera ( Chaco phytogeographic region), Villa Allende and Villa del Rosario (Espinal phytogeographic region) during April/September of two consecutive years 1989, 1990. Specific immature habitats in each locality were identified and sampled monthly. Eggs and/or immatures of Aedes albifasciatus, Ae. fluviatilis, Anopheles albitarsis, culex acharistus, Cx. apicinus, Cx. bidens, Cx. coronator, Cx. chidesteri, Cx. dolosus, Cx. maxi, Cx. quinquefasciatus, Cx. saltanensis, Psorophora ciliata and Uranotaenia lowii were collected. Three species (Cx. acharistus, Cx. dolosus and Cx. quinquefasciatus) were collected during the sampling period for all developmental stages. This suggests that immature of these species do not overwinter but continue to develop throughout the cold autumn and winter seasons.

Entre autonomie et insertion. Les grands dispositifs de la politique de la jeunesse et de la famille en Allemagne

Les débats politiques actuels en Allemagne autour de la jeunesse sont marqués par deux problèmes majeurs : un taux de chômage élevé qui indique les limites du système d'apprentissage et un faible taux de natalité qui appelle à une réorientation profonde des politiques familiales. Ces deux problèmes sont analysés à partir d'éléments historiques et factuels. Dans le domaine de l'emploi, il est difficile de déceler une politique spécifique destinée exclusivement à la jeunesse en Allemagne, car toutes les mesures ont pour objectif de permettre aux personnes en difficultés d'obtenir un diplôme scolaire et/ou une formation professionnelle. En revanche, les jeunes d'origine étrangère sont moins qualifiés et rencontrent des difficultés d'insertion sur le marché de travail, ce qui a poussé le gouvernement à développer un grand nombre de mesures spécifiques. D'un autre côté, l'Allemagne présente un très faible niveau de diplômés de l'enseignement supérieur. Ce groupe est presque épargné par les problèmes de chômage. Face aux graves problèmes démographiques qui s'annoncent, l'Allemagne repense les politiques publiques en faveur de la famille, de la jeunesse et de la solidarité entre les générations. Les nouvelles mesures proposées par la ministre de la Famille (une allocation pour les parents d'enfants ayant entre 12 et 14 mois, et la création d'ici à 2013 de nouvelles places en crèche permettant de garder un tiers des enfants) se heurtent à des méfiances anciennes vis-à-vis de l'État. Finalement, les rapports entre les générations sont repensés par la création de lieux de vie communs qui sont un moyen de faire face à la modification des structures familiales et au surnombre de personnes âgées. Dans une première partie, les nouvelles mesures d'orientation destinées aux jeunes en difficulté sont analysées dans le contexte du marché de travail. La seconde partie est consacrée à une analyse des nouveaux dispositifs des politiques familiales.

Physicians' attitudes towards prevention: importance of intervention-specific barriers and physicians' health habits.

BACKGROUND: Several studies have explored physicians' attitudes towards prevention and barriers to the delivery of preventive health interventions. However, the relative importance of these previously identified barriers, both in general terms and in the context of a number of specific preventive interventions, has not been identified. Certain barriers may only pertain to a subset of preventive interventions. OBJECTIVES: We aimed to determine the relative importance of identified barriers to preventive interventions and to explore the association between physicians' characteristics and their attitudes towards prevention. METHODS: We conducted a cross-sectional survey of 496 of the 686 (72.3% response rate) generalist physicians from three Swiss cantons through a questionnaire asking physicians to rate the general importance of eight preventive health strategies and the relative importance of seven commonly cited barriers in relation to each specific preventive health strategy. RESULTS: The proportion of physicians rating each preventive intervention as being important varied from 76% for colorectal cancer screening to 100% for blood pressure control. Lack of time and lack of patient interest were generally considered to be important barriers by 41% and 44% of physicians, respectively, but the importance of these two barriers tended to be specifically higher for counselling-based interventions. Lack of training was most notably a barrier to counselling about alcohol and nutrition. Four characteristics of physicians predicted negative attitudes toward alcohol and smoking counselling: consumption of more than three alcoholic drinks per day [odds ratio (OR) = 8.4], sedentary lifestyle (OR = 3.4), lack of national certification (OR = 2.2) and lack of awareness of their own blood pressure (OR = 2.0). CONCLUSIONS: The relative importance of specific barriers varies across preventive interventions. This points to a need for tailored practice interventions targeting the specific barriers that impede a given preventive service. The negative influence of physicians' own health behaviours indicates a need for associated population-based interventions that reduce the prevalence of high-risk behaviours in the population as a whole.

Age Structure of Adult Mosquito (Diptera: Culicidae) Populations from Buenos Aires Province, Argentina

In order to detect seasonal trends in the age structure of adult mosquitoes from Buenos Aires province, Argentina, female populations were sampled with CDC traps during 1989-1991 in Punta Lara and La Plata. The mosquitoes were dissected and age-grouped according to ovarian tracheation and ovariolar stages. All Runchomyia paranensis females were parous, suggesting that this species could be autogenous. Aedes albifasciatus showed parous peaks following population peaks, with shorter delays in spring-summmer and longer in fall-winter. Ae. crinifer and Culex dolosus showed wide fluctuations in age structure due to adult emergences during all months. Psorophora ferox showed high population replacement rates. Mansonia indubitans and Ma. titillans have few generations per year during their activity period. This is the first report on age-grading of adults of field mosquito populations from Argentina

Onchocerciasis in Ecuador: Prevalence of Infection on the Ecuador-Colombia Border in the Province of Esmeraldas

The prevalence of onchocerciasis infection was determined in communities on 7 rivers located in the northern area of the cantón San Lorenzo, province of Esmeraldas. Diagnosis of the infection was obtained by skin biopsies and recombinant-antigen based-serology. No evidence of infection was detected in 9 communities studied along the Río Mataje, which forms the frontier between Ecuador and Colombia, nor in 10 adjacent communities located on 5 interior rivers. Evidence for Onchocerca volvulus infection was found in 4 communities on the Río Tululví with the following prevalence: La Boca (3.5% by biopsy and 3.9% by serology), Guayabal (9.1% by both biopsy and serology), La Ceiva (51.5% by biopsy and 53% by serology), and Salidero (4% by biopsy and 7.7% by serology). A few individuals in these communities were seropositive for O. volvulus in the absence of detectable dermal microfilariae: these might harbor very light or prepatent infections. No clinical disease attributable to onchocerciasis was found. The infected communities will be included in the ivermectin-based National Control Program for the disease, with no evidence of the infection having extended north of the Ecuadorian-colombian border

Mesurer la pratique religieuse: différentes enquêtes, différents taux? Analyse comparative à partir de la Suisse

In Switzerland, national census data imply that 84.5 percent are affiliated with religious groups and national survey data imply that 15 percent attend a service on a given weekend in 2009. Research in other countries has shown that attendance is often over-reported, but the level of over-report varies across countries. Thus, in the United States, polls show high and stable levels of religious practice, while Church participation surveys indicate rates twice lower. This article assesses the validity of self-reported affiliation and attendance in Switzerland using the 2009 Swiss National Congregations Study (NCS). Results confirm the observation offered by others that the Swiss census undercounts the persuasions absent from the stylized response categories and they show for the first time that Swiss probably over-report their church attendance, though not as much as in the United States.

Changing Religiosity, Changing Politics? The Influence of 'Belonging' and 'Believing' on Political Attitudes in Switzerland

Starting from theories of secularization and of religious individualization, we propose a two-dimensional typology of religiosity and test its impact on political attitudes. Unlike classic conceptions of religiosity used in political studies, our typology simultaneously accounts for an individual's sense of belonging to the church (institutional dimension) and his/her personal religious beliefs (spiritual dimension). Our analysis, based on data from the World Values Survey in Switzerland (1989-2007), shows two main results. First, next to evidence of religious decline, we also find evidence of religious change with an increase in the number of people who "believe without belonging." Second, non-religious individuals and individuals who believe without belonging are significantly more permissive on issues of cultural liberalism than followers of institutionalized forms of religiosity.

Stratigraphy and palaeoenvironment of Early Jurassic dinosaur-bearing volcaniclastic deposits from Toundoute (Province of Ouarzazate, Haut-Atlas, Morocco)

The Early Jurassic dinosaur site of Toundoute which yielded the basal sauropod Tazoudasaurus naimi is examined in the light of its stratigraphic, sedimentological and palaeoenvironmental context. A thin succession of Early Liassic marine carbonates (probably Hettangian-Sinemurian in age) is continuously overlain by continental beds with dinosaurs. These latter are assumed to be of Middle to Late Liassic age. The continental deposits include a large part of volcanoclastics, different from the Triassic basalts. The Jurassic volcanoclastics originated from an unknown but obviously close eruption centre. The continental sediments (channels and flood plain) were deposited under tropical climate conditions with alternating humid and dry episodes. The bones occur as isolated or partly articulated elements (parts of carcasses). The two bone-beds are related to typical mud-flows. This type of transport protected the bones from erosion, and favoured their burying and fossilization.

Fouilles suisses à Derecik, Büyükorhan, province de Bursa (Turquie). Rapport préliminaire 2007-2008

La découverte en 2001 d'une église et de son pavement sur le site de Derecik près de la ville de Büyükorhan en Turquie a suscité de premières fouilles par les archéologues du Musée archéologique de Bursa, capitale de province, la même année. La présentation des mosaïques en 2006 aux participants d'un colloque organisé par l'Université Uludag de Bursa a permis l'intervention d'une équipe suisse sur les lieux dès 2007. Deux années de fouille et d'observations ont conduit à distinguer plusieurs phases de construction de l'église elle-même et de l'emplacement sur lequel elle est implantée. Un temple de construction légère l'a précédée, vraisemblablement dédié à Zeus, et au moins trois phases de construction la caractérisent, complétées par des aménagements postérieurs. L'occupation des lieux est attestée depuis le IIe siècle ap. J.-C., sinon avant, jusqu'aux invasions arabes du VIIIe siècle ap. J.-C.

Ethnic minority-majority asymmetry in national attitudes around the world: A multilevel analysis

Using data from the International Social Survey Programme, this research investigated asymmetric attitudes of ethnic minorities and majorities towards their country and explored the impact of human development, ethnic diversity, and social inequality as country-level moderators of national attitudes. In line with the general hypothesis of ethnic asymmetry, we found that ethnic, linguistic, and religious majorities were more identified with the nation and more strongly endorsed nationalist ideology than minorities (H1, 33 countries). Multilevel analyses revealed that this pattern of asymmetry was moderated by country-level characteristics: the difference between minorities and majorities was greatest in ethnically diverse countries and in egalitarian, low inequality contexts. We also observed a larger positive correlation between ethnic subgroup identification and both national identification and nationalism for majorities than for minorities (H2, 20 countries). A stronger overall relationship between ethnic and national identification was observed in countries with a low level of human development. The greatest minority-majority differences in the relationship between ethnic identification and national attitudes were found in egalitarian countries with a strong welfare state tradition.
