As the reach of global business operations increases, cultural context will likely influence the nature and amount of sexual harassment workers experience. Surprisingly, little is known about sexual harassment in Russia, an attractive target for expanding companies. To address this gap in the literature, we examine Russian workers’ perceptions of sexual harassment severity through the lens of cultural context. In particular, we examine the sexual harassment severity perceptions from the perspective of both targets and perpetrators. Results indicate that as targets of sexual harassment, Russian women and men held similar sexual harassment severity perceptions. However, as perpetrators, Russian women reported perceiving the harassment they committed as being less severe than the reports of Russian men. Further, among both targets and perpetrators, Russian women held less permissive sexual attitudes than Russian men, with this difference mediating the relationship between participant sex and perceived sexual harassment severity: women perceived greater severity than men because women hold less permissive sexual attitudes. Implications for research, practice, and the role of national culture in shaping the social construction of sexual harassment are discussed.  相似文献

This article presents an application of a bibliometric and visual study of the research carried out on a social science subfield, concretely the consumer behaviour research (CBR), from a longitudinal perspective (period 1966–2008). The study combines performance analysis and science mapping for detecting and visualizing conceptual subdomains. Quantitative and qualitative measures are used in order to identify the most prominent themes. Quantitative data are used to put together very related concepts (themes or clusters of topics), while qualitative indicators (as those based on citations) are used to measure the quality and/or impact of the detected themes. The study also uses bibliometric maps to show in a visual way the associations between the main concepts treated by the CBR community. The maps provide insight into the structure of the CBR, visualize the division of the field into several subfields, and indicate the relationships between these subfields. Co-word analysis is the bibliometric technique used to identify the main themes. All this allows us to quantify and visualize the thematic evolution of the CBR. It also helps to both experts and novices to understand the current state of the art of the CBR and to predict where future research could lead.  相似文献

In 2007 Nicholas Stern’s Review (in Science 317:201–202, 2007) estimated that global GDP would shrink by 5–20% due to climate change which brought forth calls to reduce emissions by 30–70% in the next 20 years. Stern’s results were contested by Weitzman (in J Econ Lit XLV(3):703–724, 2007) who argued for more modest reductions in the near term, and Nordhaus (in Science 317:201–202, 2007) who questioned the low discount rate and coefficient of relative risk aversion employed in the Stern Review, which caused him to argue that ‘the central question about global-warming policy—how much how, how fast, and how costly—remain open.’ We present a simulation model developed by Färe et al. (in Time substitution with application to data envelopment analysis, 2009) on intertemporal resource allocation that allows us to shine some light on these questions. The empirical specification here constrains the amount of undesirable output a country can produce over a given period by choosing the magnitude and timing of those reductions. We examine the production technology of 28 OECD countries over 1992–2006, in which countries produce real GDP and CO2 using capital and labor and simulate the magnitude and timing necessary to be in compliance with the Kyoto Protocol. This tells us ‘how fast’ and ‘how much’. Comparison of observed GDP and simulated GDP with the emissions constraints tells us ‘how costly’. We find these costs to be relatively low if countries are allowed reallocate production decision across time, and that emissions should be cut gradually at the beginning of the period, with larger cuts starting in 2000.  相似文献

This paper discusses the similarities and differences in the collection process between in-house and 3rd party collection. The objective is to show that, although the same type of modelling approach to estimating the Loss Given Default (LGD) can be used in both cases, the details will be significantly different. In particular, the form of the LGD distribution suggests that one needs to split the distribution in different ways in the two cases, as well as using different variables. The comparisons are made using two data sets of the collection outcomes from two sets of unsecured consumer defaulters.  相似文献

A theory of leadership is proposed and tested. Leaders perform many roles in a firm. They become leaders because they succeed at these tasks more than others and at least some of their successes are visible. The theory implies that leaders tend to be more able, place themselves in visible decision making situations more frequently and are generalists. Also, the most able leaders should be found in the highest variance industries, where decision making has the greatest payoff. The theory is tested using data on Stanford alumni and is confirmed. Leaders are generalists rather than specialists, both innately and in their pattern of skill acquisition.  相似文献

Traditionally, the role of women in business responsibility jobs has provided extensive and much discussed issues. Almost 20?years ago research on WIB was very rich. Some discussions surrounding women in business included, for instance: learning about their situation at work, their strong and weak management capabilities and possible setbacks to their promotion and consolidation in positions of responsibility. In any case, it did seem that conciliation between family and work lives, in general, was a setback for most women. By the beginning of 21st century the work of Leonard (Women??s Stud Int Forum 24:67?C78, 2001) analyzed the state-of-the-art, concluding that not much had changed in terms of the challenges faced by women. Therefore, it may seem appropriate, to readdress the situation for women in management as this new century reaches its first decade. This paper takes as a reference the context of an occidental and developed country such as Spain. We develop a multi-case study which allows us to (i) analyze the opinion of a group of women and men who work in high and intermediate management positions, (ii) defend the suitability to overcome the differences between men and women and (iii) admit the consideration of different female profiles. In such cases, firms may take several advantages stemming from both gender and personal characteristics.  相似文献

This paper tests the impact of guanxi on behaviors among firms in a Chinese marketing channel. Guanxi is operationalized in this paper as emotional closeness and interactive state. We find that the emotional closeness between channel-boundary personnel of firms has a positive impact on their exercise of noncoercive power, a negative impact on their exercise of coercive power, and a negative impact on the perceived conflict between them. In addition, emotional closeness has an indirect but positive impact on perceived cooperation. Interactive state between the boundary personnel of two firms has a positive impact on a firm exercising noncoercive power and a negative impact on perceived conflict between them. At the same time, it is positively related to a firm exercising coercive power. This shows not only the significant influence of guanxi on a firm's channel behaviors but also the constructive effects of both emotional closeness and interactive state on marketing channel behaviors in China.  相似文献

Buyers' perspectives of buyer-seller relationship development   总被引:1,自引:0,他引:1  
Long-term buyer-seller relationships have been a focus of research for several years. The present study draws on interaction/network theory to test a model examining the interaction mechanisms and relationship characteristics of buyer-seller relationships during four progressive phases of relationship development. Data from 174 members of the Institute for Supply Management offer empirical support for the associations proposed in the model, as well as some surprising results. One of the most useful findings of the research is that the patterns of these associations vary as buyer-seller relationships progress through the four phases of relationship development. Specifically: in the awareness phase, joint problem solving increases buyer uncertainty; in the exploration phase, communication quality and joint problem solving increase relationship-specific investments; and in the expansion phase, joint problem solving increases relationship-specific investments and severe conflict resolution increases buyer uncertainty. Seller reputation moderates many of these relationships. The major conclusion of the research is that buyers and sellers should recognize that while information exchange and conflict resolution are important aspects of buyer-seller relationships, their use may not always lead to the desired relationship characteristics. Managerial implications of these findings and further research ideas are presented.  相似文献

The European Emission Trading Scheme (EU-ETS) is the first large-scale and inter-regional trading scheme for greenhouse gas emissions. It is seen as the central instrument of European climate policy. After a first testing-phase (2005–2007), the second trading period of the EU-ETS had started in 2008, with stronger incentives for investment in low-carbon technologies and carbon dioxide abatement. However, there is hardly any evidence how emissions trading fares in practice. The KfW/ZEW CO2 Barometer shows that trading of emission permits is actively used by 75 percent of German companies, but the price-signals that stem from the EU-ETS were relatively weak so far—too weak to set strong incentives for carbon dioxide emission reductions on the company-level. Also in the case of the ‘clean development mechanism’ (CDM) which was introduced to promote emission reductions in developing counties, there is need for further development.  相似文献

This paper is an exercise in the history of thought, which compares Austrian and neoclassical theories of the emergence of private property rights, and examines, in part, the extent to which Austrians can be said to offer a commonly-agreed upon explanation that parallels Carl Menger's exemplary story of the emergence of money. We address the sources of disagreement (and apparent conflict) among emergence theorists in both schools. We try to show that some of the disagreement hinges on an unclear meaning of the term “emergence,” which is resolvable, while other sources of disagreement are fundamental at the methodological level.
