Abstract in Uncoded languages achtergrond De incidentie van schizofrenie bij migranten lijkt verhoogd. doel Kwantificeren van het risico op schizofrenie bij migratie. methode Meta-analyse van Engelstalige publicaties over incidentieonderzoeken uit de periode 1977-2003. resultaten Het gemiddelde, gewogen relatieve risico (rr) van schizofrenie was 2,7 (95%- betrouwbaarheidsinterval (bi) 2,3-3,2) voobackground There is evidence of an increased incidence of schizophrenia in immigrants. aim To provide a quantitative index of the effect size associated with immigration. method We performed a meta-analysis of English-language incidence studies that were published between 1977 and 2003. results The mean, weighted relative risk (rr) was 2.7 (95%- confidence interval (ci) 2.3- 3.2) for first-generat

The major histocompatibility complex (MHC) has a central role in the specific immune defence of vertebrates. Exon 3 of MHC class I genes encodes the domain that binds and presents peptides from pathogens that trigger immune reactions. Here we develop a fast population screening method for detecting genetic variation in the MHC class I genes of birds. We found evidence of at least 15 exon 3 sequenc

The implementation of the Bologna Process (BP) did not go as smoothly as the Bologna Follow-Up evaluations suggest, and the consequences of the BP for the various European higher education systems and universities are much more diverse than represented in these various studies. Relatively few research and policy documents taking a more critical stance are currently available while a systematic ove

Delayed-acceptance Markov chain Monte Carlo (DA-MCMC) samples from a probability distribution, via a two-stages version of the Metropolis-Hastings algorithm, by combining the target distribution with a "surrogate" (i.e. an approximate and computationally cheaper version) of said distribution. DA-MCMC accelerates MCMC sampling in complex applications, while still targeting the exact distribution. W

Objective: To define the role of ultrasound (US) for the assessment of patients with rheumatoid arthritis (RA) in clinical remission, including joint and tendon evaluation. Methods: A multicentre longitudinal study has been promoted by the US Study Group of the Italian Society for Rheumatology. 25 Italian centres participated, enrolling consecutive patients with RA in clinical remission. All patie

STUDY QUESTION: Is there an association between the number of oocytes retrieved for IVF, and perinatal and obstetric outcomes? SUMMARY ANSWER: No significant association was found between the number of oocytes retrieved and perinatal outcomes, while an association was found for placenta praevia and male gender. WHAT IS KNOWN ALREADY: Previous studies have shown that between 6 and 15 oocytes retrie

Background: Adjuvant chemotherapy (ACT) for breast cancer improves relapse-free survival (BCRFS) and overall survival. Differences in terms of efficacy and toxicity could partly be explained by the significant interpatient variability in pharmacokinetics which cannot be captured by dosing according to body surface area. Consequently, tailored dosing was prospectively evaluated in the PANTHER trial

Summary form only given. The advanced resource connector (ARC), or the NorduGrid middleware, is an open source software solution enabling production quality computational and data grids. Since the first release (May 2002), the middleware is deployed and being used in production environments. Emphasis is put on scalability, stability, reliability and performance of the middleware. A growing number

The structure and function of proteins are strongly affected by the surrounding solvent water, for example through hydrogen bonds and the hydrophobic effect. These interactions depend not only on the position, but also on the orientation, of the water molecules around the protein. Therefore, it is often vital to know the detailed orientations of the surrounding ordered water molecules. Such inform

We discuss the associated cc¯ and l+l- pairs production in ultraperipheral heavy-ion collisions at high energies. Such a channel provides a novel probe for double-parton scattering (DPS) at small x enabling one to probe the photon density inside the nucleus. We have derived an analog of the standard central pp pocket formula and studied the kinematical dependence of the effective cross section. Ta

Accurate age data are essential for reliable fish stock assessment. Yet many stocks suffer from inconsistencies in age interpretation. A new approach to obtain age makes use of the chemical composition of otoliths. This study validates the periodicity of recurrent patterns in25 Mg,31 P,34 K,55 Mn,63 Cu,64 Zn,66 Zn,85 Rb,88 Sr,138 Ba, and208 Pb in Baltic cod (Gadus morhua) otoliths from tag–recaptu

In interstadial deposits, sand interbeds gain limited consideration in comparison with organic sediments, and therefore tend to be underrepresented in paleoenvironmental reconstructions. The Raunis site, central-eastern Latvia, is an example where organic beds have already gained some attention and been used to understand the complex interactions between advance and retreat of the Scandinavian Ice

Although the use of location-based data (location coupled with semantic information) within Geographical Information Systems (GIS) and from Earth Observation (e.g. satellite) sources has been long established for decision makers, this has only recently been reflected in the construction sector with a more recent move from Computer Aided Design (CAD) to Building Information Modelling. BIM has opene

In Sweden, a large share of public services are organised, produced and delivered by municipalities, large and small, rich and poor. Contextual conditions (size and location) and economic conditions (efficiency and wealth) differ considerably among these service-providing organisations. The question raised in this paper is whether a municipality's economic situation is a direct consequence of the

Concrete hardens as a result of chemical reactions between water and cement. Cement is a hydraulic binder, in the reaction the cement binds water-molecules. This is an exoterm process, heat is produced during the reactions. How fast this process proceeds is much depending of the temperature. The amount of heat produced during the hardening of the concrete is also depending on the thickness of the

Georgia is facing social and economic challenges and at the same time there are signs that more pressure is put on the environment and natural resources. Georgian industry is energy- intense and encompassing deregulations have put even more stress on the environment. How to combine economic and social goals with environmental concerns has been a hotbed for disputes in Georgia. A recognized approac
