T he main objective of this study is to estimate the spatial spillover effects of the economic growth among the selected countries of MENA region. For this purpose, the Spatial Durbin Model in the framework of spatial dynamic panel data was estimated during the period of 1970-2010. The spatial Diagnostic tests affirmed the occurrence of spatial positive autocorrelation phenomenon for...

This paper investigates the impact of geography on technological diffusion via international trade and proposes to re-examine the contribution of Coe, Helpman and Hoffmaister to the knowledge spillovers literature. Using a gravitational model, we first confirm the negative effect of physical distance on imports. We also show that geographic proximity contributes to more technological diffusion ...

JEL Classification Code(s): J 31, J 71) "Perceptions of Discrimination, Effort to Obtain Psychological Balance, and Relative Wages: Can We Infer a Happiness Gradient?" There is a substantial literature that finds a linkage between happiness and relative economic well being as measured by earnings or wages. There is also a well documented racial gap in wages. One explanation for this is disparat...

Methods for determining inter-spin distances between nitroxide spin labels from dipolar couplings in the intermediate range (r12≈1.1-2 nm) by CW-EPR are addressed. For nitroxide powder patterns, the assumption of unlike spins is a better approximation than assuming strong coupling between like spins. Methods that determine the average splitting in dipolar deconvolutions yield the mean value 〈1/...

US federal transfers to individuals are large, countercyclical, vary geographically, and often credited with helping stabilize regional economies. This paper estimates the short-run effects of these using plausibly exogenous variation in temporary stimulus payments permanent Social Security benefit increases. States that received larger tended grow faster contemporaneously, a multiplier around ...

Background: Mena is an immunofluorescence-based, quantitative method in which expression of the noninvasive Mena protein isoform (Mena11a) is subtracted from total Mena protein expression. Previous work has found a significant positive association between Mena and risk of death from breast cancer. Our goal was to determine if Mena could be used as an independent prognostic marker for axillary n...

The spread of cancer during metastatic disease requires that tumor cells subvert normal regulatory networks governing cell motility to invade surrounding tissues and migrate toward blood and lymphatic vessels. Enabled (Ena)/vasodilator-stimulated phosphoprotein (VASP) proteins regulate cell motility by controlling the geometry of assembling actin networks. Mena, an Ena/VASP protein, is upregula...

The cytoskeleton regulatory protein Mena is reportedly overexpressed in breast cancer; however, data regarding its expression level and clinical significance in gastric carcinoma (GC) is limited. The aim of the present study was to investigate Mena expression levels and prognostic significance in GC. Mena mRNA expression level was determined by reverse transcription-quantitative polymerase chai...
