While many studies of knowledge exchange have been undertaken in private and service organizations, government and R&D enterprises, few have studied scientific inter‐organizational collaborations. Furthermore, in the literature on international networks there has been a tendency to assume that knowledge exchange will be inevitably enhanced by global dispersion. Two linked dynamics deserving further study are the role of geographic proximity and the role of information and communication technologies in facilitating knowledge flow across international networks. Studies of intra‐ and inter‐firm knowledge transfer, managerial work values and cultural norms all point to China as being a fascinating counterpoint for the way knowledge exchange might occur in Europe. So in this study of the ATLAS collaboration, a ‘big science’ global network of 3,500 physicists, we explore the perceptions of two subgroups: UK physicists working in Europe and Chinese scientists based in Beijing and HeFei. Findings from 24 interviews and non‐participant observation reveal that face‐to‐face working at European Organization for Nuclear Research (Geneva) is not without its difficulties, but for a variety of sociocultural reasons, it is primarily the Chinese scientists who perceive themselves to be inhibited from full participation in effective knowledge exchange.  相似文献

This paper investigates the characteristics of firms which have underrepresented groups in top management positions and those which do not. It is argued that profiles of these characteristics will be different for firms with minorities vs. women and that these profiles will be different depending on whether representation is by board membership or through officerships. A discriminant analysis found both similarities and differences in variables that were associated with these different forms of representation. It was found, for example, that size is associated with representation for both minorities and women, whereas high advertising intensity is associated with firms with women on board, but not as officers. Other findings and the implications of the study are discussed.Jerry Fryxell is an Assistant Professor of Management at the University of Tennessee — Knoxville.

This article describes the epidemiology of injuries collected in the Injury Surveillance System in Leon Hospital in Nicaragua. A total of 6659 persons were treated for injuries in 2004. It was discovered that 88% of all injuries were unintentional, 9% involved interpersonal violence, 2% were self-inflicted and 0.2% was undetermined. Men accounted for 64.7% of the cases, with the highest rate among 20 - 24 year olds (5625.8 per 100,000 inhabitants). Among women, the highest rate was in those aged 64 years and older (5324.2 per 100 000 inhabitants). The most common mechanisms were falls (33.9%), blunt force (26.8%), cut/pierce/stab (15.1%) and transportation-related (12.8%). These results indicate the need to identify prevention strategies for those injuries that were most commonly treated in emergency, such as unintentional falls among older women, self-inflicted poisoning among young women and blunt force and transportation-related injuries among young men.  相似文献

Pulse Fishing and Stock Uncertainty   总被引:1,自引:0,他引:1  
Large variation in stock dynamics affects the accuracy of stock estimates, which fisheries managers rely on when determining quotas and other regulations. The purpose of this paper is to investigate the implications of uncertainty on pulse fishing. We show that as the variance of the random natural fluctuations increases, the optimal pulse length decreases and converge toward a constant-escapement policy. Hence, in fisheries with large natural variability, a constant-escapement policy is a good approximation of the optimal policy.  相似文献

We determine the optimal investment strategy for an ambiguity-averse investor in a setting with stochastic interest rates. The investor has access to stocks, bonds, and a bank account and he is ambiguous about the expected rate of return of both bonds and stocks. The investor can have different levels of ambiguity aversion about the two types of risky assets. We find that it is more important to take model uncertainty about the stock dynamics than model uncertainty about the bond dynamics into account. Furthermore, the investor’s ambiguity increases his hedging demand. Consequently, the bond/stock ratio increases with his ambiguity and implies less extreme positions in the bank account. Altogether, our model yields portfolio allocations which are more in line with what is implementable in practice. Finally, we demonstrate that neglecting model uncertainty implies significant losses for the investor.  相似文献

Public accounting firms (e.g., Grant Thornton, 2012) are stressing an interest in recruiting accounting students with a proficiency in Excel. The purpose of this study is to investigate which Excel functions are perceived to be important and useful for new hires to understand prior to starting a job in public accounting. We collect survey data from four large public accounting firms as well as undergraduate and graduate accounting students (i.e., potential new hires) to gauge perceptions of Excel importance, knowledge, and usage in public accounting. We find that employees at the firms believe the most important Excel functions are: basic formula, filter and sort data, vertical (horizontal) lookup, formatting of documents, and If/Then statements. In a comparison of new hires at public accounting firms with accounting students, results suggest that accounting students underestimate the importance and usage of some of these Excel functions. In addition, results suggest that new hires’ perceived knowledge on how to use specific Excel functions in their accounting job is statistically different than students’ perceived knowledge on how to use some of the same Excel functions. Our research contributes to educational accounting literature by documenting which Excel functions employers in public accounting want new hires to know prior to starting a job in public accounting. Also, this research informs accounting educators that students’ perceptions are not the same as public accounting employers’ expectations with respect to analytical skills using Excel technology.  相似文献

Georgia's lottery-funded HOPE Scholarship program provides free tuition to in-state students who can maintain a B average at state universities. However, roughly half of HOPE Scholars lose their support after their freshman year. This study employs student-level administrative data to identify the observed characteristics that systematically relate to scholarship attrition. Conditional on measures of student ability, there are not statistically significant differences between white, black, and Hispanic students. However, there are dramatic differences across academic disciplines. Students majoring in science, engineering, and computing are 21 to 51 percent more likely to lose their HOPE Scholarships than students in other disciplines.  相似文献

The authors’ research in Hungary during the period of transition to a market economy provides an opportunity to examine the evolving relationships between consumer product knowledge and its antecedents, including advertising, personal search, interpersonal sources, and brand experience. Their findings, based on survey data collected in Budapest in 1992 and 1998, indicate that the market information variables explain more variance in consumer knowledge later rather than earlier in the transition. Advertising is an important predictor of consumer knowledge later but not earlier in the transition, personal search is important at both times, and interpersonal sources are not important in either time period; brand experience is negatively related to knowledge earlier in the transition and positively related later in the transition. This study allows one to begin to understand the boundary conditions associated with studies conducted in developed economies. Managerial implications for firms investing in transitional economies are presented. Robin A.

Abstract

This paper uses dictator experiments to examine gender differences in altruistic behavior in the United States when decisions are made individually and jointly. In anonymous individual giving to charity, women give substantially more than men, and in paired settings, mixed-sex groups give the most while all male pairs give the least. Evidence supports social information and negotiation effects as participants change giving toward that of their partners. Social image effects are found only in mixed-sex groups, indicating a gender-based component to the value of the social signal sent. Although men and women appear to have similar influence, the positive social image effect pushes giving in mixed-sex pairs above the sum of the members' individual gifts because the less altruistic partners (usually men) adjust their giving upward more than the more altruistic partners (usually women) reduce giving. Therefore, increasing women's participation in traditionally male spheres of decision making may result in more altruistic economic behavior.  相似文献
