The aim of this paper is to assess the impact of information technology (IT) on the productivity and efficiency of manufacturing industries in Iran. So, the data will be collected from 23 Iranian manufacturing industries during “2002–2006” and the methods such as DEA and panel data used to study the subject. Results obtained by the above two methods represent that IT has a positive and statisti...

In this research we model and estimate the effects on productivity downstream from information technology (IT) investments made upstream. Specifically, we examine how one industry’s productivity is affected by the IT capital stock of its suppliers. These supplier-driven IT spillovers occur because, due to competition in the supplying industry, quality benefits from suppliers’ IT investments can...

BACKGROUND and AIMS The ESPACES study was intended to identify retirees who may have been, according to their job descriptions, exposed to asbestos during their working lives. As part of this study, we analysed the quality of the occupation and activity sector coding as well as its effect on the subjects' exposure status. METHODS The occupation and activity sector for a sample of 450 retire...

Empirical research has shown tremendous productivity di erences, even within narrowly de ned industries. A great host of studies is explainsing this productivity disparity by factors such as idiosyncratic technology shocks, input price di erences, management skills, or international trade. Although these explanations are undoubtedly important, the current paper suggests that product diversi cat...

This study presents an empirical evidence concerning the comparison of  the dynamics of competitiveness in the creative and manufacturing industries. It investigated the impact of the economic crisis in the behavior of the competitiveness of those industries. The samples were 42 firms taken from 3 sub-sectors of the creative industries and 3 sub-sectors of the manufacturing industries listed in...

This study investigates the determinants of advertising intensity using panel data on 66 four-digit Turkish manufacturing industries from 1993–1999. The results pooled OLS and fixed-effects regressions support a quadratic relationship between concentration: Advertising first increases with concentration ratio, when ratio rises above certain threshold, in decrease intensity. also indicate that m...

Recently Just-In-Time (JIT) production has attracted increasing interest throughout the Chinese manufacturing industries and its programs have been widely implemented. Currently, there are few studies conducted about JIT manufacturing implemented by small manufacturing firms in China, even though small firms are still dominant in many areas of manufacturing industries in China. This study analy...

The importance of manufacturing strategy (MS) has never been questioned and has been emphasized in many theoretical concepts, frameworks, and models. There are only a few empirical studies, however, which examine whether these theories work in practice. In this paper the hypothesis that the existence of MS contributes to company level competitiveness (ROS, inventory turnover) is tested. The stu...

background: the interaction between serum neuron-specific enolase (nse), biogenic amino-acids and neurobehavioral function with blood lead levels in workers exposed to lead form lead-acid battery manufacturing process was not studied. objective: to evaluate serum nse and biogenic amino-acids (dopamine and serotonin) levels, and neurobehavioral performance among workers exposed to lead from lead...
