This study examined the emergence of corporate social responsibility (CSR) as a public issue over 25 years using a content analysis of two national news- papers and seven regional, geographically-dispersed newspapers in the U.S. The present study adopted a comprehensive definition encompassing all four CSR dimensions: economic, ethical, legal, and philanthropic. This study examined newspaper editorials, letters to the editor, op-ed columns, news analyses, and guest columns for three aspects: media attention, media prominence, and media valence. Results showed an increase in the number of opinion pieces covering CSR issues over the 25-year period. The prominence of each of the four CSR dimensions varied over time. Each of the four CSR dimensions had its moment of media prominence when it was more important than the other dimensions. The most prevalent valence of the opinion pieces was negative; the volume of negative pieces increased over the 25 years, whereas the number of opinions with positive, neutral, and mixed tones showed little change over time. The study concludes by tracing the implications of the role of the news media for business ethics research.  相似文献

The state of the nation’s infrastructure is the subject of widespread discussion and comment because it is thought to include many deteriorating and unsafe bridges. Ever since the terrorist attacks of 9/11, there has been increasing concern over the extent to which an attack on infrastructure could result in serious economic disruption. This research develops a model to analyze the economic consequences of an attack on a major element of the highway network. We add a freight network to a national multiregional economic impact model and make freight traffic flows endogenous. The use of a sub-national interstate model recognizes that most infrastructure planning is at the state level and most political leaders’ interest is local. We base our approach on the National Interstate Economic Model (NIEMO) and refer to an elaboration that we name Transportation network and the National Interstate Economic Model (TransNIEMO). The new model enables us to study the state-specific and industry-specific economic impacts of some significant changes in the nature of highway freight movements. We tested the model for selected freight movements in and out of California. The results are entirely plausible and encourage us to elaborate and test the model for hypothetical disruptions of freight traffic throughout the US.  相似文献

This paper reports on a study of current practice in policy transfer, and ways in which its effectiveness can be increased. A literature review identifies important factors in examining the transfer of policies. Results of interviews in eleven cities in Northern Europe and North America investigate these factors further.The principal motivations for policy transfer were strategic need and curiosity. Local officials and politicians dominated the process of initiating policy transfer, and local officials were also the leading players in transferring experience.A range of information sources are used in the search process but human interaction was the most important source of learning for two main reasons. First, there is too much information available through the Internet and the search techniques are not seen to be wholly effective in identifying the necessary information. Secondly, the information available on websites, portals and even good practice guides is not seen to be of mixed quality with risks of focussing only on successful implementation and therefore subject to some bias. Officials therefore rely on their trusted networks of peers for lessons as here they can access the ‘real implementation’ story and the unwritten lessons. Organisations which have a culture that is supportive of learning from elsewhere had strong and broad networks of external contacts and resourced their development whilst others are more insular or inward looking and reluctant to invest in policy lessons from elsewhere. Solutions to the problems identified in the evidence base are proposed.City to city policy transfer is a very active process in the field of transport. Not enough is yet understood about its benefits or the conditions under which it is most effective. Such understandings should help to promote and accelerate the uptake of effective and well matched policies.  相似文献

The spread of invasive species (IS) is an inherently spatial process, and management of invasive species occurs over spatially heterogeneous regions, but policy constraints can restrict management responses to be homogeneous across regions. Using a spatial bioeconomic model that includes a representation of invasive species ecology based on heterogeneous environments that are linked across space and time by human and ecological pathways, we compare optimal spatially heterogeneous policy to spatially uniform policy. We explore the magnitude and pattern of the policy differences with emphasis on the influence of different types of underlying heterogeneity across locations.  相似文献

This paper reports on a study of the networking and linkage practices of technology and non-technology firms within the Ottawa cluster. The work seeks to understand how and why particular patterns of networks and linkages evolve and it examines empirically the usage and value of networks and linkages. Previous work argues that technology firms need to be relatively more adept at developing external relationships in order to be successful than do non-technology based companies. This work, however, finds that technology firms exhibit fewer linkages than non-technology based companies do within the Ottawa cluster. The research suggests that the vitality of the Ottawa cluster could be further enhanced through the promotion of additional networking and linkages among regional firms. A key implication for management practice is that CEOs of technology-based firms should work towards establishing and maintaining additional valued relationships.  相似文献

Research on international differences in retail productivity has highlighted formidable environmental barriers to the ‘industrialisation’ of mass retailing as a driver of declining British interwar productivity growth in this sector (and in services more generally). We examine evidence for such barriers, using a case study of a firm that built its interwar expansion strategy on ‘American’ retail methods – Marks & Spencer (M&S). We find that, rather than facing barriers to the adoption of American mass retail practices, M&S reaped major productivity gains from this process. This adds further evidence to an emerging literature rejecting the barriers to industrialisation thesis for retailing.  相似文献

Before the formation of the Federal Reserve, banking panics were routine events in the United States. During the most severe episodes, banks in cities across the country would often suspend or restrict the par convertibility of their demand deposit liabilities. In diagnosing the causes of the Great Depression, Friedman and Schwartz famously regard these local initiatives as a second best solution, which in the absence of an effective lender of last resort would have prevented the rash of bank failures during the early 1930s and their dire monetary and real impacts. Recent research in macroeconomics though has raised the possibility that banks’ suspension of payments might also have negative real effects albeit through changes in aggregate supply such as the financing of working capital. We would expect to observe these negative shocks during the pre-Fed era, because the decentralized, private interbank payments network was especially vulnerable to systemic disruptions such as suspensions by New York and other money center banks. Reports in national trade periodicals and local newspapers during suspension periods offer many accounts of factories closing because of the inability to obtain currency for weekly payrolls and “domestic exchange” to finance internal trade. We corroborate these observations with more systematic econometric evidence at the national and regional levels. Our results show that controlling for the overall contraction and bank failures, suspension periods were associated with a statistically significant and quantitatively large decline in real activity, on the order of 10–20 %.  相似文献

This paper addresses researchers’ call for integrating workplace spirituality with organizational literature. This paper points out that self-interest transcendence is a common aspect in the workplace spirituality concept that emerged in the last decade and also in four OB concepts – transformational leadership, organizational citizenship behavior, organizational support, and procedural justice – that emerged in OB about two decades ago. Based on this common aspect of self-interest transcendence and the temporal precedence of these four OB concepts’ emergence, it indicates that these four OB concepts constitute a precursor of workplace spirituality. It places workplace spirituality in the larger context of OB␣and outlines the associated research and practice implications. The author also holds a lien on the position of professor at XLRI School of Business and Human Resources, India.  相似文献

Single-parent families are becoming a larger part of American society. But what is known about their decision-making processes? Role strain is of particular interest when studying single parents because of their need to serve multiple family roles otherwise carried out by dual-parent families. In this study, the consumer decision process for single parents is empirically examined in the context of grocery shopping. Role strain was found to have a significant effect on problem recognition style and reactive shopping behaviors. Advertising positively influenced proactive shopping behaviors and had a negative relationship with reactive shopping behaviors. Implications for food retailers are provided.  相似文献

This study examines the role that a website plays in the development of fan allegiance and as a promotion management tool for a sports team and brand. Research indicates that the combination of sports, media (television in particular), and sponsorships when employed in an integrated manner, can develop consumer connection to brands. This study suggests that the Internet is also an important part of an integration strategy of sports, media, and promotion. By working with a new team in the AIFA indoor football league, the researchers were able to determine what helped make fans allegiant to the team before the franchise's inaugural game. The results show that even before the team played its inaugural home contest, fans had become allegiant to the franchise brand and team by using the team internet site. These results indicate that an internet site can serve as a strong promotional tool in an integrated marketing plan of sports, media, and promotion to move fans toward brand loyalty and toward primary goals of the firm, including increased sales.  相似文献
