BACKGROUND The aim of the present cross-sectional study was to examine work- and nonwork- related factors and physical and mental health outcomes associated with combined time- and strain-based work-life conflict (WLC) among adult employees living and working in Switzerland as well as possible gender differences in this regard. METHODS The data used for the study were taken from wave 6 of the...
We use a white-light continuum (WLC) Z-scan technique to measure the degenerate two-photon absorption spectrum and associated dispersion of the nonlinear refraction in ZnSe. The spectral components of the WLC source are separated by using a narrow band variable filter to minimize nondegenerate nonlinearities. We observe a change in sign of the ultrafast nonlinear refractive index around 0.7 of ...
The mechanics of DNA bending on intermediate length scales (5-100 nm) plays a key role in many cellular processes, and is also important in the fabrication of artificial DNA structures, but previous experimental studies of DNA mechanics have focused on longer length scales than these. We use high-resolution atomic force microscopy on individual DNA molecules to obtain a direct measurement of th...
We propose an interpolation formula (the EV-WLC relation) for the force-extension behavior of wormlike chains in the presence of hard-core excluded volume interactions, analogous to the classic interpolation formula from Marko and Siggia for ideal wormlike chains. Using pruned-enriched Rosenbluth method (PERM) simulations of asymptotically long, discrete wormlike chains in an external force, we...
The objectives of this study were, first, to examine domain-specific antecedents of work-life conflict (i.e., job demands and home demands), second, to investigate, turnover intention, job satisfaction and organizational commitment as outcomes of work-life conflict relevant to organizations, and, finally, to study the role of job autonomy as a buffer between work-life conflict and these organiz...
Main results After adjustment for age, age of onset of disorder, sex, and baseline ratings, CT groups showed greater reductions in symptoms after 6 months than the WLC group (BDI, p=0.02; ISS-DEP, p=0.01; ISS-ACT, p=0.007; and ISS-PC, p=0.01) and greater improvement in global functioning as shown by change on the GAF (p=0.05) (table). CT group patients showed greater improvement in social activ...
برنامه ریزی تفرجی در اکوتوریسم (طبیعت گردی) نه تنها به عنوان ابزاری برای ارتقای سطوح اجتماعی و اقتصادی مردم تلقی می شود، بلکه به علت کارکردهای حفاظتی زمینه حفاظت پویای منابع طبیعی را نیز مهیا می کند. با توجه به اینکه اولین قدم در برنامه ریزی برای هر نوع فعالیتی ارزیابی پتانسیل سرزمین برای آن فعالیت است، در این مطالعه به ارزیابی پتانسیل طبیعت گردی حوضه آبخیز بابلرود در استان مازندران با استفاده ...
We give an extended review of recent numerical and analytical studies on semiflexible chains near surfaces undertaken at Institut Charles Sadron (sometimes in collaboration) with a focus on static properties. The statistical physics of thin confined layers, strict two-dimensional (2D) layers and adsorption layers (both at equilibrium with the dilute bath and from irreversible chemisorption) are...
مفهوم بهینه سازی سازه ها حدود 60 سال پیش معرفی شده است . اولین بار اشمیت از دانشگاه لوس آنجلس ( کالیفرنیا ) فکر ترکیب تحلیل اجزای محدود و بهینه سازی را عنوان کرده است (1960) . همکنون این شیوه کاملا درک شده و موارد متعددی به کار می رود و نرم افزارهای مناسبی نیز برایش گسترش یافته است . در این مقاله در ترکیب روش اجزای محدود و تحلیل بهینه سازی نا خطی برای طراحی بهینه ی سازه های ساندویچی از نظر حداق...
CONTEXT Childhood mood disorders lack sufficient evidence-based treatments. While psychosocial treatments are recommended for both childhood depression and bipolar disorder, empirical support is scarce. OBJECTIVE To determine whether adjunctive multifamily psychoeducational psychotherapy would improve outcome for children aged 8 to 12 years with depression or bipolar disorder. DESIGN One hu...
