Social network sites (SNSs) have become so popular that the number of people joining and actively participating on such sites is increasing on a daily basis. Although there are several SNSs, Facebook is currently the most popular and most commonly used. SNSs have primarily been developed with able-bodied people in mind and as a result of this, people with disabilities find it difficult to join and participate on these sites. Furthermore, this topic has received little attention by researchers around the world. Facebook pages usually consist of text, graphics, and sound where the users navigate through the pages using a mouse. As a step towards addressing this need and finding a possible elegant solution, the authors have developed a voice-activated PC-based system (called NEU-FACE) in the form of an interface to Facebook. With the aid of this system, a person with a physical disability can join and participate in Facebook by giving voice commands to manage the typical Facebook activities.
This paper empirically examines the effects of export product diversification on overall export quality in a panel data set of 115 countries from 1970 to 2010. It uses the data sets of the overall export quality and three export diversification measures of the International Monetary Fund: the extensive margin (variation in the number of new products exported), the intensive margin (variation in export values among existing exports), and the overall (Theil) index. It finds that export quality has only been increasing with a higher variation in export values among existing exports in low- and lower-middle-income countries. It also observes that export quality has been increasing with both a higher variation in export values among existing exports and new products exported in upper-middle- and high-income countries. The results are robust to the changing measures of controls in the benchmark model, the inclusion of many other controls; i.e. various measures of globalization, country size, factor endowments, macroeconomic stance, etc., and the exclusion of outliers. 相似文献
This study examines the impact of deregulation and technological change on the productivity of Malaysian banks over the period 1989–1998. Malmquist indices constructed with nonparametric DEA techniques are decomposed into their pure efficiency, scale efficiency, and technological change components. Our findings indicate an erosion of banking productivity that masks divergent tendencies among its component elements. These are dominated by adverse effects of technological change, which are associated with a reduction in the labor intensity of banking activity. Consistent with the mixed findings reported in the literature, the present investigation suggests that regulatory reform and liberalization are not sufficient conditions for productivity improvement.JEL classification: D24, G21This paper was written while Dogan was a member of Monash University Malaysia.
