The Rev. Dr. Martin Luther King, Jr. wrote extensively on economic matters, especially unemployment policy. King supported a federal job guarantee for anyone ready and willing to work. He believed it would provide employment and income security, as well as increased public and community services. Dr. King's writings on employment are reviewed and discussed. His policy proposals are just as relevant today as they were when they were first put forward some forty years ago.  相似文献

Driven by the proliferation of augmented reality (AR) technologies, many firms are pursuing a strategy of service augmentation to enhance customers’ online service experiences. Drawing on situated cognition theory, the authors show that AR-based service augmentation enhances customer value perceptions by simultaneously providing simulated physical control and environmental embedding. The resulting authentic situated experience, manifested in a feeling of spatial presence, functions as a mediator and also predicts customer decision comfort. Furthermore, the effect of spatial presence on utilitarian value perceptions is greater for customers who are disposed toward verbal rather than visual information processing, and the positive effect on decision comfort is attenuated by customers’ privacy concerns.  相似文献

During many manmade and natural crises such as terrorist threats, floods, hazardous chemical and gas leaks, emergency personnel need to estimate the time in which people can evacuate from the affected urban area. Knowing an estimated evacuation time for a given crisis, emergency personnel can plan and prepare accordingly with the understanding that the actual evacuation time will take longer. Given the urban area to be evacuated, street widths exiting the area's perimeter, the area's population density, average vehicle occupancy, transport mode share and crawl speed, an estimation of traffic evacuation time can be derived. Peak-hour traffic data collected at three, midblock, Mumbai sites of varying geometric features and traffic composition were used in calibrating a model that estimates peak-hour traffic flow rates. Model validation revealed a correlation coefficient of +0.98 between observed and predicted peak-hour flow rates. A methodology is developed that estimates traffic evacuation time using the model.  相似文献

The last three decades have witnessed the continued exit of households from primary agriculture in the United States, where the average annual gross exit rate has averaged 10% per year. Understanding exit behavior is one key to future farm structure, management of abandoned land, depopulation of rural areas, and agricultural policy, including government program payments. This study empirically estimates the determinants of exit decisions of farm households. Particular attention is given to the roles of intensity of government payments and off‐farm work decisions of farm couples in the exit decision. Using a large farm‐level survey and controlling for endogeneity, results indicate that farm households with reduced intensity of government payments are more likely to exit farming. Households where the operator spouse works off the farm are more likely to exit farming. Additionally, households with older farmers, with the farm operator and spouse raised on a farm, and households operating farms located in Northern Great Plains are more likely to exit farming.  相似文献

Injuries related to agricultural equipment are a significant cause of morbidity and mortality, in both high-income and low-income countries. Tractors are most often associated with severe injuries and fatalities. All age groups sustain injuries. Injuries to children are also prevalent because the sites of agricultural work overlap homes in rural areas. In the majority of papers reviewed, preventive methods are mostly targeted at behaviour modification and effective medical facilities, whereas only a few authors have highlighted design changes and passive measures for injury control. The effectiveness of suggested interventions is not discussed in the majority of papers except those related to roll-over protection structures, fodder cutting machines and thresher safety devices.  相似文献

The main objective of the paper is to elaborate and suggest positive note on basic agenda existing in Middle East resisting the women entrepreneur growth development and use of ICT. The entrepreneurship among the women in Arabic countries has been lately given due consideration. In order for develop women entrepreneurship for economic growth their must be strong move by all stakeholders. ICT enables women entrepreneurs to extend equal participation compared to the male in the growth and development of the nation’s economy. The extended use of ICT will help the entrepreneur for creating advantage, research; participate in the global world of business for technology transfer, training, collaboration, and development initiatives at the global level. The paper tries to highlight the barrier for women for entrepreneurial growth and use of ICT with special reference to Middle East countries. The case related to women in two gulf countries will elaborate the deep insight of the issue.  相似文献

A significant number of less developed countries (LDCs), including Ghana, have embraced the World Bank/IMF led economic reforms. Ghana has been implementing these reforms since the early 1980. One of the conditions of the reforms is the privatization of former state-owned enterprises (SOEs). Such privatization activities have however generated debates among academics, practitioners, and policy makers. Research findings so far have been mixed. This paper analyzes the performance of two large privatized companies in Ghana. Both companies have been paraded by the Ghanaian authorities and the international financial community as success stories of privatization. Our objective is to examine how and why these firms have been claimed to be successful. Drawing on the dimensions of the balanced scorecard, we examine the performance of the firms from five main perspectives—financial, customers, internal business process, learning and growth, and the community. The analysis is based on data gathered from diverse sources, namely, semi-structured interviews and discussions with managers of the selected companies and with personnel from key government departments, and analysis of internal and external documents. We conclude that, overall the performance of both organizations improved after privatization under all the performance dimensions examined. These improvements were also accompanied by certain organizational changes, including changes in the accounting and control systems. However we are not claiming that all privatization programs in Ghana have been successful. In fact there are stories in the Ghanaian media of several other privatization failures in the country. Instead what we have demonstrated is the need to explain the performance of privatized firms beyond the myopic macro-level and financial analysis which has been widely adopted by the international financial community and policy makers and we encourage other researchers to adopt such multidimensional approaches.  相似文献

While radical product innovations represent significant engines of firm growth, questions remain over whether marketing helps or hurts (1) a firm's radical product innovation activity and (2) its rewards from radical product innovation activity. By attaching an attention‐based view of the firm to a market‐based assets view of marketing, this paper examines the role of three marketing resources—market knowledge, reputation, and relational resources—on radical innovation activity. Our conceptual framework posits differentiated effects among marketing resources as antecedents of radical innovation activity and as moderators of its impact on firms' financial performance. Using a survey of a broad set of high‐tech business‐to‐business (B2B) firms to test hypotheses, it is found that firms with strong relational resources enjoy a higher propensity for, and stronger financial rewards from, radical innovation activity. Reputational resources come with a trade‐off as they hurt the incidence of radical innovation but enhance its financial rewards. However, market knowledge resources appear to hurt both radical innovation activity and its financial rewards. Our results point to the multifaceted role of marketing in radical innovation activity, which is unlikely to come with a single benefit or liability as prior work often posits. Rather, our research heightens the alertness of managers to assess their firms' marketing strength as a bundle of stocks of several marketing resources. Managers must understand the distinct benefits and drawbacks of each resource in developing and launching radical innovations. Our research underscores the differentiated value of marketing in radical innovation activity in B2B high‐tech contrary to the entrenched idea of a limited or even stifling role of marketing in this context.  相似文献

This paper examines the determinants of inside spreads and their behaviour around corporate earning announcement dates, for a sample of UK firms over the period 1986–94. The paper finds that closing daily inside spreads are affected by order processing costs (proxied by trading volumes), inventory control costs (trading volumes and return variability) and asymmetric information (unusually high trading volumes). Inside spreads start to narrow 15 days before an earnings announcement, and narrow further by the end of the announcement day. We also identify a puzzling phenomenon. There is only a 'sluggish' recovery of spreads after the announcement: inside spreads continue to remain at relatively narrow levels, and take up to 90 days to recover to their pre–announcement width.  相似文献
