Using a new dataset on imports of technology and total factor productivity (TFP) over more than a century for the OECD countries, this paper tests for international technological transmission through trade. The empirical estimates suggest that imports of knowledge have been responsible for an almost 200% increase in TFP over the past century, but that the spillover effect has been highly uneven...

This paper provides a dynamic optimization model of durable good inventories to study the interactions between investment demand and production of capital goods. There are three major findings: First, capital suppliers’ inventory behavior makes investment demand more volatile in equilibrium; Second, equilibrium price of capital is characterized by downward stickiness; Third, the responses of th...

The aim of the study is to investigate the influence of prenatal temperature stimulation on neuronal NO synthase (nNOS) expression in the anterior hypothalamus of Muscovy duck embryos. Experiments were performed on embryonic day (E) E20, E23, E28, and E33 using histochemistry for identification of the nicotinamide adenine dinucleotide phosphate-diaphorase (NADPH-d) as marker of NOS-containing n...

Pancreatic β-cell ATP-sensitive K(+) (K(ATP)) channels are composed of Kir6.2 and SUR1 subunits encoded by the KCNJ11 and ABCC8 genes, respectively. Although rare monogenic activating mutations in these genes cause overt neonatal diabetes, the common variants E23K (KCNJ11) and S1369A (ABCC8) form a tightly heritable haplotype that is associated with an increased susceptibility to type 2 diabete...

To exploit overexpression of erbB2 in human cancers, we constructed a single-chain immunotoxin (erb-38) that contains the Fv portion of monoclonal antibody e23 fused to a truncated form of Pseudomonas exotoxin A. In a Phase I study, five breast cancer patients and one esophageal cancer patient received three doses of erb-38 at 1.0 and 2.0 microg/kg. Hepatotoxicity was observed in all patients. ...

We reevaluate the role of human capital in determining the wealth of nations. We use standard human capital theory to estimate stocks of human capital and allow the quality of human capital to vary across countries. Our model can explain differences in schooling and earnings profiles and, consequently, estimates of Mincerian rates of return across countries. We find that effective human capital...

We study a resource constrained assembly line balancing problem (RCALBP) presented by Ağpak and Gökçen, who developed a 0-1 integer programming model to find the optimal solution. However, this model is inefficient in solving large-scale problems. In this paper, we propose a simple efficient heuristic that is based on the widely-used ranked positional weight (RPW) rule. The example given by Ağp...

A meta-analysis was performed to compare cervical arthroplasty with anterior cervical diskectomy and fusion for single-level cervical spondylosis. A comprehensive search was conducted with PubMed, Embase, and the Cochrane Central Register of Controlled Trials from January 1, 2000, to April 30, 2015. Random-effects models were used for heterogeneous data. Fixed-effects models were used for poole...

China has experienced remarkably stable growth and inflation in recent years according to official statistics. We use systematic discrepancies between cross-sectional and time-series Engel curves to construct alternative estimates of Chinese growth and inflation. Our estimates suggest that official statistics present a smoothed version of reality. Official inflation rose in the 2000s, but our e...
