With statistics pointing to nearly 100% adoption of mobile phones in developed countries and nearly 50% adoption worldwide, mobile phones have become a pervasive portion of our information and communications infrastructure. In many developing countries, mobiles are becoming an important platform for delivering information services. Yet in spite of its rapid adoption, does this mean that cell ph...

Structural change plays an important role in developing any economy, so understanding it is critical to make policies that increase total factor productivity. The structural change that leads to an efficient resource allocation after trade reforms is desirable; the key factor that can affect the relation of "structural change and trade liberalization" with productivity is the quality of institu...

P roductivity promotion has received a key attention in contemporary macroeconomic analysis. Productivity of labor driven, in particular, by human capital (i.e. health and education), is seen vitally more important. Labor qualities in terms of health and education (treated as flow and stock variables), have a bearing on labor productivity. The main objective of this paper is to ident...

a r t i c l e i n f o This paper presents a theoretical model of firm-specific productivity growth that incorporates technological knowledge by electrification and tests the model empirically. Our theoretical explanations suggest that the energy-transformation from fossil fuel to electricity by electrification could cause a decrease in the short-term level of productivity but an increase in the...

conclusions the stereotactic brachytherapy for patients with circumscribed and relatively small size tumors appears to be a safe, feasible, and minimally-invasive treatment. results thirteen patients were male and 16 were female, with the median age of 29 years (range, 2.5 – 64 years). the median follow-up was 95 (range, 6 – 240) months. based on pignatti classification, 10 patients were at low...

introduction: stress is associated with neurological and cognitive disorders. it has been suggested that doxepin, in addition to its influence on the content of neurotransmitters, has probable neuroprotective effects as well. therefore, the aim of this study was to investigate the effects of doxepin on synaptic plasticity and brain-derived neurotrophic factor (bdnf) gene expression in the rat h...

long-term potentiation (ltp) is a reflection of synaptic plasticity that induced by specific patterns of synaptic activity and has an important role in learning and memory. the first clue of the potential role of glutamate receptors in ltp was in 1991 with the observation that the mglur agonists 1-amino-1, 3-cyclopentanedicarboxylic acid (acpd), increased ltp. studies have shown that acpd induc...
