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 examines the effects of disclosing greenhouse gas (GHG) information mandatorily on the cost of equity capital (COC) using a longitudinal unbalanced panel database of the United Kingdom's FTSE 350 firms for the period 2011–2016. We use a nonlinear panel quantile regression (PQR) model to examine the relationship between GHG disclosure (GHGD) and COC in the United Kingdom. This technique was supplemented by conducting a two-step generalised method of moment (GMM) estimation to address any concerns related to the potential existence of endogeneity problems. Our findings suggest that high-level GHGD appeared to be negatively associated with COC up to a certain level, which is known as the turning point; then, any increase in GHGD is likely to increase the COC. This means that the nonlinear association between GHGD and COC is evidenced in our study and takes a U shape. Likewise, our findings are associative of a moderating effect of the 2013 carbon disclosure regulation (CDR) on the GHGD–COC nexus. We argue that mandatory GHGD and GHG risk are linked so that those companies that are associated with higher GHG risk have a tendency to be better disclosers. Consequently, we urge regulators to design GHGD regulations in a way that mirrors corporate environmental risk and leads to a lower COC in order to align the interests of corporations with those of the society at large.  相似文献

This study assesses the impact of traffic sign deficit on road traffic accidents in Nigeria. The participants were 720 commercial vehicle drivers. While simple random sampling was used to select 6 out of 137 federal highways, stratified random sampling was used to select six categories of commercial vehicle drivers. The study used qual-dominant mixed methods approach comprising key informant interviews; group interviews; field observation; policy appraisal and secondary literature on traffic signs. Result shows that the failure of government to provide and maintain traffic signs in order to guide road users through the numerous accident black spots on the highways is the major cause of road accidents in Nigeria. The study argues that provision and maintenance of traffic signs present opportunity to promoting safety on the highways and achieving the sustainable development goals.  相似文献

For many if not most publicly traded companies, acquisition capabilities remain a critical component of sustainable longterm growth and profitability. And even as investors press companies to return excess capital through dividends and stock buybacks, the market continues to assign premium valuations to companies that earn above-average returns through a combination of internal investment and judicious acquisition spending.
This article begins by describing major challenges facing acquirers in the current business and regulatory environment. Then, after showing how M&A can be used to address strategic goals, the authors identify key elements in the M&A strategies of three highly successful companies: General Electric, Danaher, and Illinois Tool Works.  相似文献

This paper examines the behavior of the risk premium component of currency forward rates. Analyzing forward rates of one, two and three-month maturity, we find that the power of forward rate as a predictor of future spot rate decreases with the length of contract maturity. Further, we find that the proportion of the variance of the forward premium which is due to the variation of the risk premium is larger than the proportion due to the expected spot rate change for all currencies except for the Canadian dollar. This proportion also increases with the length of maturity.  相似文献

We examine the role of index futures trading in spot market volatility. We use the exponential generalized autoregressive conditional heteroskedasticity (EGARCH) approach to measure volatility, analyze causality and feedback relations between volatilities in the spot and futures markets, and test various hypotheses in the context of a multivariate model that incorporates other macrostate variables. Our empirical results suggest index futures trading may not be blamed for the observed volatility in the spot market. Rather, we find stronger and more consistent support for the alternative posture that volatility in the futures market is an outgrowth of a turbulent cash market. We use the regret (cognitive dissonance) theory to explain our results.  相似文献

In investigating the causal relation between government revenue and spending, our empirical results support the tax-and-spend hypothesis for Egypt and the fiscal synchronization hypothesis for Jordan. Breaking away from these historical trends is essential for both countries to eliminate the budget deficit and therefore ensure the availability of domestic saving for private investment. To cope with unemployment and poverty, continuing privatization is recommended for both countries to improve productivity and efficiency in the domestic economy. Privatization should lead to higher domestic saving and investment and at the same time eliminate the budget deficit by enhancing revenue and curbing spending. (JEL H62, H63)  相似文献

Drawing on the literature on social comparison and equity theories, this paper analyses the determinants of, and the relationships between, the cash pay awards of CEOs and other board members for a sample of large UK companies over the period 1992–95. Our results suggest that external labour market and internal (i.e., within board) pay comparisons are important in explaining both CEO and other directors' pay awards. In the case of CEOs, however, there is evidence of an asymmetric adjustment to prior period pay anomalies, whereby the pay of the relatively underpaid executives displays significantly greater sensitivity to external market comparison pay levels. This asymmetric adjustment process results in a 'bidding-up' of average CEO pay relative to other board members over the four year period investigated.  相似文献

Corporate mergers possibly enhance the labor negotiation advantage of employers. This study investigates the association between wage levels and merger activity to test the employer bargaining strength hypothesis. The results indicate significantly lower union wages as a consequence of merging. Merger activity, however, does not influence wage levels of non-union workers. These findings are supportive of the employer bargaining strength hypothesis.  相似文献

The last thirty years have witnessed the appearance and rapid expansion of Islamic banking both inside and outside the Islamic world. Islamic banks provide financial products that do not violate Sharia , the Islamic law of human conduct. The Islamic principles upon which the banks claim to operate give an important role to social issues. Applying these principles, we develop a benchmark set of social disclosures appropriate to Islamic banks. These are then compared, using a disclosure index approach, the actual social disclosures contained in the annual reports of twenty-nine Islamic banks (located in sixteen countries) to this benchmark. In addition, content analysis is undertaken to measure the volume of social disclosures. Our analysis suggests that social reporting by Islamic banks falls significantly short of our expectations. The results of the analysis also suggest that banks required to pay the Islamic religious tax Zakah provide more social disclosures than banks not subject to Zakah .  相似文献
