HIV disclosure and nondisclosure among migrant women from sub-Saharan Africa living in Switzerland.

No study to date has focused specifically on the reasons for and against disclosure of HIV-positive status among sub-Saharan migrant women. Thirty HIV-positive women from 11 sub-Saharan countries living in French-speaking Switzerland participated in semi-structured individual interviews. The reasons women reported for disclosure or nondisclosure of their HIV serostatus were classified into three categories: social, medical, and ethical. The women identified the stigma associated with HIV as a major social reason for nondisclosure. However, this study identifies new trends related to disclosure for medical and ethical reasons. Being undetectable played an important role in the life of sub-Saharan migrant women, and analysis revealed their medical reasons for both disclosure and nondisclosure. Disclosure to new sexual partners occurred when women had a more positive perception about HIV and when they believed themselves to be in a long-term relationship. Women reported nondisclosure to family members when they did not need help outside the support provided by the medical and social fields. The results on ethical reasons suggested that challenging stigma was a reason for disclosure. Since the women' perceptions on HIV changed when they came to see it as a chronic disease, disclosure occurred in an attempt to normalize life with HIV in their communities in migration and to challenge racism and discrimination. Our findings can help health providers better understand the communication needs of sub-Saharan migrant women with respect to HIV/AIDS and sexuality and offer them adequate disclosure advice that takes into account migration and gender issues.

Amphibians in the diet of European Barn Owls

We present a review of the propensity to eat amphibians in the Barn Owl Tyto alba in Europe. Based on the analysis of 596 published studies reporting 3.32 million prey items identified in pellets, 17 869 amphibians (0.54%) were found. An analysis of 9036 amphibians identified to the species level showed that Barn Owls avoid consuming toxic species, and they are able to capture tree frogs (Hylidae) only rarely. The true frogs (Ranidae) are by far the most frequently captured amphibians followed by spadefoot toads (Pelobatidae) and Parsley frogs (Pelodytidae).

Nosocomial bloodstream infection and clinical sepsis

Primary bloodstream infection (BSI) is a leading, preventable infectious complication in critically ill patients and has a negative impact on patients' outcome. Surveillance definitions for primary BSI distinguish those that are microbiologically documented from those that are not. The latter is known as clinical sepsis, but information on its epidemiologic importance is limited. We analyzed prospective on-site surveillance data of nosocomial infections in a medical intensive care unit. Of the 113 episodes of primary BSI, 33 (29%) were microbiologically documented. The overall BSI infection rate was 19.8 episodes per 1,000 central-line days (confidence interval [CI] 95%, 16.1 to 23.6); the rate fell to 5.8 (CI 3.8 to 7.8) when only microbiologically documented episodes were considered. Exposure to vascular devices was similar in patients with clinical sepsis and patients with microbiologically documented BSI. We conclude that laboratory-based surveillance alone will underestimate the incidence of primary BSI and thus jeopardize benchmarking.

Schizotypy and hemispheric asymmetry: results from two Chapman scales, the O-LIFE questionnaire, and two laterality measures

Schizotypy is a multidimensional personality construct representing the extension of psychosis-like traits into the general population. Schizotypy has been associated with attenuated expressions of many of the same neuropsychological abnormalities as schizophrenia, including atypical pattern of functional hemispheric asymmetry. Unfortunately, the previous literature on links between schizotypy and hemispheric asymmetry is inconsistent with some research indicating that elevated schizotypy is associated with relative right over left hemisphere shifts, left over right hemisphere shifts, bilateral impairments, or with no hemispheric differences at all. This inconsistency may result from different methodologies, scales, and / or sex proportions between studies. In a within-participant design, we tested for the four possible links between laterality and schizotypy by comparing the relationship between two common self-report measures of multidimensional schizotypy (the O-LIFE questionnaire, and two Chapman scales, magical ideation and physical anhedonia) and performance in two computerized lateralised hemifield paradigms (lexical decision, chimeric face processing) in 80 men and 79 women. Results for the two scales and two tasks did not unequivocally support any of the four possible links. We discuss the possibilities that a link between schizotypy and laterality 1) exists, but is subtle, probably fluctuating, unable to be assessed by traditional methodologies used here; 2) does not exist, or 3) is indirect, mediated by other factors (e.g. stress-responsiveness, handedness, drug use) whose influences need further exploration.

The importance of micro-habitat in the breeding of Barn Owls Tyto alba

Capsule Habitat parameters associated with 706 Barn Owl (Tyto alba) nesting boxes in Israel were analysed. Pairs bred in 259 of the boxes. The intensity of agricultural practices at nestbox sites were shown to have only a weak effect on aspects of Barn Owl breeding in this region.

Governing International Migration through Partnership

Partnerships in international migration governance promise a cooperative approach between countries of origin, transit and destination. The literature has generally conceptualised migration partnerships as a policy instrument. This article suggests that understanding the broader transformations taking place in international migration governance under the rubric of partnership demands a novel analysis. Using a governmentality perspective, I interpret migration partnerships as an instance of neoliberal rule. Focusing on the convergence of international migration governance between the international realm and the European and North American region in particular, I demonstrate that the partnership approach frames international migration governance so as to enlist governments, migrants and particular experts in governing international migration, and invokes specific technologies of neoliberal governing which contribute to producing responsible, self-disciplined partners who can be trusted to govern themselves according to the norms established by the partnership discourse. The partnership approach is not a mere policy instrument; it goes beyond the European region and has become an essential element of the governance of international migration.

An ultrastructural approach to analogies between fungal structures and needle fibre calcite

Needle fiber calcite (NFC) is an ubiquitous terrestrial secondary calcium carbonate mineral often associated with calcitic nanofibers. NFC's origin has been debated for a long time and a fungal origin is often proposed. Fungi are known to be involved in mineral weathering and production of metal oxalate, but little information exists regarding the genesis of other minerals, such as calcite. In this study, a comparison of similar ultrastructural characteristics of fungal hyphae and NFC has been performed to highlight analogies between both features. These analogies clearly demonstrate the probable close relationship between fungal filaments (hyphae and rhizomorphs) and NFC and its associated nanofibers.

Non-verbal behavioural patterns in trilogue play transitions and family alliances

This case study focuses on non-verbal behaviour in father-mother-infant triads. Analyses were done on transitional moments during which the partners exchanged an active role for a participant-observer role, or vice versa. Transitions are known to be crucial moments for revealing familial transactional mechanisms. Our sample was comprised of six non-clinical families, characterized by different types of functional or problematic alliances (which is the degree of coordination between the partners). Our methodology included micro-analysis of body and gaze formations, facial expressions, and so on. Data were analysed using the research package 'THEME' for the detection of hidden patterns. Different types of non-verbal patterns were found, which may be prototypes corresponding to the different types of alliance. The patterns of the families with high alliances had a more elaborate construction and were more efficient for the concluding of transitions than the patterns of families with low alliances, which were either elementary or laborious.

The Poor Representation of the Poor in a Comparative Perspective

Due to diverging levels of political influence of various income groups, political institutions likely reflect¦the policy preferences of certain groups of citizens better than others, independently of their numerical¦weight. This runs counter the egalitarian principle of 'one citizen, one vote'. The present article documents¦a general trend of underrepresentation of the preferences of relatively poor citizens both by¦parties and by governments across Western democracies, although important cross-national differences¦exist.

Towards better Olympic accountability

Ten years after the corruption scandal that shook the International Olympic Committee (IOC) in 1999, this article presents the current situation regarding accountability for this non-governmental organization based in Switzerland. The IOC is responsible for ensuring that the Olympic Games are held regularly, and since its foundation has endeavoured to promote sport without discrimination in service of sustainable human development and a better world. Olympic accountability is examined by means of four facets within a theoretical framework. The analysis of each of them shows that although considerable progress has been made by the IOC since 1999, improvements regarding accountability remain both possible and desirable. A mechanism for making improvements is proposed in the Conclusion.
