Using a strict, age-specific lockdown order for adults aged 65 and older in Turkey, we examine the mental health consequences of an extended period tight mobility restrictions on senior adults. Adopting regression discontinuity design, find that curfew-induced decline substantially worsened outcomes, including somatic nonsomatic symptoms distress (approximately 0.2 standard deviation). Explorin...

august wilson is undoubtedly one of the rare black playwrights whose works have attracted streams of attention and worldwide audience. the present study aims at analyzing fences and piano lesson which are two of the most successful plays in his pittsburgh cycle from the perspective of michel foucault’s theories and ideas. studying these two plays from foucault’s perspective opens new windows in...

This paper focuses on evaluation of the impact of the global financial crisis on the process of real convergence within the EU28 economies. The beta-convergence approach is verified by the use of crosssectional linear regression analysis. The sigma-convergence is tested by standard deviation of real GDP per capita. The aim is to verify the hypothesis that the betaand sigma-convergence (βand σ-c...

This research examines whether technology transfer, research intensity, educational attainment and the ability to absorb foreign technology help explain cross-country differences in productivity growth. Our data comprise a panel of 55 countries including 23 OECD and 32 developing economies over the period 1970-2004. The results show that TFP growth in both OECD and developing countries is posit...

Using 1959—1991 growth rates for 449 4-digit US manufacturing industries, I test ‘idea’ and ‘rival human capital’ models of endogenous growth. I find the following: First, TFP growth is faster in industries that are more intensive in capital and intermediate goods and less intensive in labor, favoring idea models over rival human capital models. Second, industries with rapidly declining prices ...

fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...

testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...

Case study evidence suggests that exporting firms learn from their clients. But econometric evidence, mostly using exporting and TFP growth, is mixed. We use a UK panel data set with firm-level information on exporting and productivity. Our innovation is that we also have direct data on the sources of learning (in this case about new technologies). Controlling for fixed effects we have two main...

in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
