In search of maximizing efficiency, public organizations found solace in the adoption of employee performance management (EPM) systems. While research supports that managing employees’ performance has favourable outcomes, it is still unclear why and under which conditions. Moreover, EPM systems might even create additional pressures and therefore increase turnover intentions and undermine public organization’s quest to maximize efficiency. We argue that when EPM systems are carried out consistently (i.e. internal consistency) and when they link civil servants’ individual goals to the organization’s strategic goals (i.e. vertical alignment), civil servants will be less likely to leave the organization. Hierarchical linear regression analysis shows that internal consistency relates to increased satisfaction with the EPM system and affective commitment to the organization. Vertical alignment relates to lower levels of turnover intentions. This relationship was mediated by EPM system satisfaction and affective commitment. These findings that contribute to our understanding of EPM systems can lead to favourable outcomes.  相似文献

A sizeable percentage of investors are using social media to obtain information about companies (Cogent Research [2008]). As a consequence, social media content about firms may have an impact on stock prices (Hachman [2011]). Various studies utilize social media content to forecast stock market-related factors such as returns, volatility, or trading volume. The objective of this article is to investigate whether a bidirectional intraday relationship between stock returns and volatility and tweets exists. The study analyzed 150,180 minute-by-minute stock price and tweet data for the 30 stocks in the Dow Jones Industrial Average over a random 13-day interval from June 2 to June 18, 2014 using a BEKK-MVGARCH methodology. Findings indicate that 87% of stock returns are influenced by lagged innovations of the tweets data, but there is little evidence to support that the direction is reciprocal, with only 7% of tweets being influenced by lagged innovations of the stock returns. Results further show that the lagged innovations from 40 percent of stock returns affect the current conditional volatility of the tweets, while 73 percent of tweets affect the current conditional volatility of stock returns. Moreover, there is strong evidence to suggest that the volatility originating from the returns to the tweets persists for 33 percent of stocks; the volatility originating from the tweets to the returns persists for 73 percent of stocks. Last, 53 percent of stocks exhibit both immediate and persistent impacts from returns to tweets, while 90 percent of stocks exhibit both immediate and persistent impacts from tweets to returns. These results may help traders achieve superior returns by buying and selling individual stocks or options. Also, asset and mutual fund managers may benefit by developing a social media strategy.  相似文献

In this paper, it is argued that outsiders play an important role in the dynamics of technical change and that, for this reason, outsider involvement is also an important entry if one wants to 'improve' or democratize technical development. Outsiders are defined as people not involved in technical development and not sharing the rules that guide the design and development of a technology. The totality of these rules makes up the technological regime of a technology. Technological regimes are characterized by certain trajectories of technical development. The focus in this paper is on outsiders who may trigger (radical) technical change that transform current technological regimes. Three different types of such outsiders are distinguished and their role in technical development is discussed: professional scientists and engineers, outsider firms and societal pressure groups.  相似文献

This paper presents a large-scale experiment on the Approval Voting rule that took place during the 2002 French presidential election. We describe the experiment and its main results. The findings are as follows: (i) Such an experiment is feasible, and very well accepted by voters. (ii) The principle of approval voting is easily understood and accepted. (iii) Within the observed political context, compared to the official first-round vote, approval voting modifies the overall ranking of candidates. (iv) The candidates Le Pen and Chirac, more than the others, were able to convert approval votes into official first-round votes. JEL Classification C93, D70, D72  相似文献

This study examines whether corporate social responsibility (CSR) performance impacts financial audit fees of U.S. listed firms from 2000 to 2016. We use the CSR performance ratings from the KLD database to measure firms' CSR performance. Using the sum of a firm's CSR strengths and concerns as a measure of a firm's overall involvement in CSR‐related matters, we find that a greater score is associated with higher audit fees. Further, we disaggregate this measure into CSR concerns and CSR strengths and find that both measures are positively related to audit fees. In additional analyses, we find that firms involved in certain CSR initiatives (strengths) as well as controversies (concerns) pay higher audit fees due to increased audit complexity. Our findings suggest that firms' CSR performance is a source of audit complexity, in addition to other sources that have been documented in prior literature.  相似文献

We investigate whether recent changes in welfare policy affect the migration of low-educated unmarried mothers. Estimates indicate that welfare reform is associated with an increase in employment-related intrastate migration, and a decrease in non-employment related migration, both within and between states. The net effect was a small increase in intrastate migration and a small decrease in interstate migration. The close link between migration and employment suggests that welfare reform has motivated low-income women to move for economic reasons. In general, welfare policy appears to have a much larger effect on residential location because of its relationship to employment than because of benefit differences between states.  相似文献

We show how differences in aggregate human development outcomes over time and space can be additively decomposed into a pure mean income (growth) component, a component attributed to differences in the distribution of income, and components attributed to ‘non‐income’ factors and differences in the model linking outcomes to income and non‐income characteristics. The income effect at the micro level is modelled non‐parametrically, so as to flexibly reflect potentially complex distributional changes. Our proposed method is illustrated using data for Morocco and Vietnam, and the results offer some surprising insights into the observed aggregate gains in schooling attainments.  相似文献

Disaster relief presents many unique logistics challenges, with problems including damaged transportation infrastructure, limited communication, and coordination of multiple agents. Central to disaster relief logistics is the distribution of life-saving commodities to beneficiaries. Operations research models have potential to help relief agencies save lives and money, maintain standards of humanitarianism and fairness and maximize the use of limited resources amid post-disaster chaos. Through interviews with aid organizations, reviews of their publications, and a literature review of operations research models in transportation of relief goods, this paper provides an analysis of the use of such models from the perspective of both practitioners and academics. With the complexity of disaster relief distribution and the relatively small number of journal articles written on it, this is an area with potential for helping relief organizations and for tremendous growth in operations research.  相似文献

The authors examine theory and research on team intimacy and team cohesion, and argue that the two have often been confused, merged, and used interchangeably in recent theoretical, empirical, and applied work on team effectiveness. The authors propose distinct definitions to clarify and distinguish between team intimacy and team cohesion, and suggest areas that will aid research and application. Their examination provides a framework for understanding the inconsistent findings in team effectiveness and team building research and thus helps to improve human resource management (HRM) interventions.  相似文献
