Researching religion and migration 20 years after ‘9/11’:Taking stock and looking ahead

This contribution to the special issue on religion and migration reviews two decades of large-scale survey research on changes in immigrant religion and the relationship between immigrants’ level of religiosity and their integration into European societies. The body of work reveals that Muslims in European societies stand out due to their comparatively high levels of religiosity and greater stability in religiosity over time and across immigrant generations. While the comparative picture is rather clear, findings regarding the long-term trend in Muslims’ religiosity and its association with immigrant integration are instead inconclusive. A systematic review of empirical studies of the association of (various indicators of) individual religiosity with immigrant integration reveals positive, negative and non-significant results for all outcomes and domains. Thus, based on the current state of art it is hard to assess whether and why religion forms a bridge or barrier to immigrant integration in Europe. To move the field forward, the contribution ends with a twofold proposal for a research agenda that includes a broadened empirical scope, moving beyond the focus on Sunni Muslims, and a conceptual extension that focuses on differences in reasoning about religion and religious meaning-making as additional, potentially more consistent and more powerful explanation for immigrants’ social relations and positions in their new societie

Older workers and employer-provided training in the Netherlands: a vignette study

Older workers throughout Europe are increasingly expected to participate longer in the labour market. While training appears to increase workers’ employability, prior research indicates that employers are less prone to provide training with increasing age of the workers. In this study, we aim to provide a better understanding of what affects employers’ considerations. We conduct a vignette experiment among Dutch employers to investigate how the government and workers themselves can exert influence on employers’ willingness to provide training. Our analyses show that employers’ provision of training declines with workers’ age, and additionally reveal two mitigating mechanisms. First, government reimbursements appear to work as a buffer: when reimbursements are offered, the decline in employers’ willingness to offer training is less pronounced throughout workers’ careers. Second, workers’ interest in training has a delaying effect: when workers are interested in training, employers’ willingness to provide training remains rather stable until workers are aged about 55, and decreases only afterwards. This contrasts the constant decline with age when workers had no interest in training. Our findings emphasise that employers’ considerations cannot be understood without taking the context into account, because governments and workers can affect employers’ decisions through cost reduction and social exchange relations, respectively. More research is needed to disentangle other possible underlying mechanisms

Fractal Conductance Fluctuations of Classical Origin

In mesoscopic systems conductance fluctuations are a sensitive probe of electron dynamics and chaotic phenomena. We show that the conductance of a purely classical chaotic system with either fully chaotic or mixed phase space generically exhibits fractal conductance fluctuations unrelated to quantum interference. This might explain the unexpected dependence of the fractal dimension of the conductance curves on the (quantum) phase breaking length observed in experiments on semiconductor quantum dots.Comment: 5 pages, 4 figures, to appear in PR

Efficacy of tofacitinib monotherapy in methotrexate-naive patients with early or established rheumatoid arthritis.

IntroductionTofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). Tofacitinib monotherapy was previously shown to inhibit structural damage, reduce clinical signs and symptoms of RA, and improve physical functioning over 24 months in methotrexate (MTX)-naive adult patients with RA. In this post hoc analysis, we compared efficacy and safety of tofacitinib in patients with early (disease duration <1 year) versus established (≥1 year) RA.MethodsMTX-naive patients ≥18 years with active RA received tofacitinib monotherapy (5 or 10 mg two times a day, or MTX monotherapy, in a 24-month Phase 3 trial.ResultsOf 956 patients (tofacitinib 5 mg two times a day, n=373; tofacitinib 10 mg two times a day, n=397; MTX, n=186), 54% had early RA. Baseline disease activity and functional disability were similar in both groups; radiographic damage was greater in patients with established RA. At month 24, clinical response rates were significantly greater in patients with early versus established RA in the tofacitinib 5 mg two times a day group. Both tofacitinib doses had greater effects on clinical, functional and radiographic improvements at 1 and 2 years compared with MTX, independent of disease duration. No new safety signals were observed.ConclusionsTreatment response was generally similar in early and established RA; significantly greater improvements were observed at month 24 with tofacitinib 5 mg two times a day in early versus established RA. Tofacitinib 5 and 10 mg two times a day demonstrated greater efficacy versus MTX irrespective of disease duration. No difference in safety profiles was observed between patients with early or established RA.Trial registration numberNCT01039688; Results

Nonlinear Dynamics of Composite Fermions in Nanostructures

We outline a theory describing the quasi-classical dynamics of composite fermions in the fractional quantum Hall regime in the potentials of arbitrary nanostructures. By an appropriate parametrization of time we show that their trajectories are independent of their mass and dispersion. This allows to study the dynamics in terms of an effective Hamiltonian although the actual dispersion is as yet unknown. The applicability of the theory is verified in the case of antidot arrays where it explains details of magnetoresistance measurements and thus confirms the existence of these quasiparticles.Comment: submitted to Europhys.
