ABSTRACT

This paper aims to explore the conceptual potential of the Deleuzian notion of the encounter in order to better understand the genealogy of opportunities. We adopt a processual perspective of opportunities. In order to translate this notion to the domain of entrepreneurship, we analysed and interpreted Jean-Marc Vallée’s Dallas Buyers Club. This film follows the creation of the first club in the United States that illegally allowed HIV-positive people to supply themselves with foreign antiretroviral drugs from Mexico or Japan. The article highlights encounters in this process that disturb the entrepreneur’s belief systems and allow him or her to be open to potential opportunity. It finally explores how the encounter may improve our understanding of the political becoming of opportunities within the entrepreneurial process.  相似文献

Systems’ thinking places high value on understanding the context. This study focused on the collection of disaggregated data in order to understand the context, to facilitate improvement of health outcomes. The aim of this article was to assess the implementation of municipal ward-based health data collection (disaggregated data) and health care workers’ perceptions of this data collection process. This cross-sectional study used mixed methods in Amajuba district. The participants were professional nurses at the Primary Health Care level. Of the 131 respondents, 123 (93.9%) collected municipal ward-based health data, and found it useful. Opportunities for improving data collection were identified. Disaggregation of the data at ward level contributes to a better understanding of the target population’s health, assists planning for health needs and enables provision of targeted interventions in order to improve health outcomes, to prevent financial regression and waste of health resources.  相似文献

This study explores relationships between race, gender, agreeableness, openness to experience, contact, and a measure of attitudes toward diversity—universal‐diverse orientation (UDO). UDO consists of three attitudinal components: realistic appreciation (a cognition), comfort with difference (a feeling), and diversity of contact (a behavior). Results suggest that race, agreeableness, and openness relate to UDO attitudes, primarily due to the relationships of these variables with the behavioral component—diversity of contact. Identifying characteristics of tolerant people (e.g., agreeableness) and training managers in skills related to those characteristics may improve contextual performance and make managers better role models within the organizational context. © 2003 Wiley Periodicals, Inc.  相似文献

Several studies find that bond rating downgrades cause negative valuation effects. Other studies find that signals conveyed by earnings releases, earnings forecasts, bankruptcies, and stock offerings of individual firms can be transmitted to their corresponding industries. By combining the two sets of studies, we hypothesize that bond rating changes may contain relevant information not only about the firm, but also about the corresponding industry. We find significantly negative valuation effects for rating downgrades, which are transmitted throughout the industry. Furthermore, we find that intra-industry effects depend on particular characteristics of the bond downgrade, the downgraded firm, and industry rivals. Specifically, the negative intra-industry effects are more pronounced when (1) the downgraded firm experiences a more severe share price response to the bond rating downgrade, (2) the downgraded firm is dominant in the industry, (3) the downgraded firm is more closely related to its rivals in the industry, and (4) the downgrade is due to a deterioration in the firm's financial prospects.  相似文献

A common assumption in equilibrium search and matching models of the labour market is that each firm posts a wage, to be paid to any worker hired. This paper considers the implications of firms posting contracts , in a random matching model with on-the-job search. More complex contracts enable firms to address both recruitment and retention problems by, for example, increasing the wage with tenure. The effect on the labour market is to reduce turnover, below the level required for efficient matching of workers to firms.  相似文献

We examine voting by a board designed to mitigate conflicts of interest between privately informed insiders and owners. Our model demonstrates that, as argued by researchers and the business press, boards with a majority of trustworthy but uninformed “watchdogs” can implement institutionally preferred policies. Our laboratory experiments strongly support this conclusion. Our model also highlights the necessity of penalties on insiders when there is dissension among board members. However, penalties for dissent appeared to have little impact on the experimental outcomes.  相似文献

We examine the impact of the events leading up to and including the passage of the Financial Services Modernization Act (FSMA) of 1999 on the stock returns of banks, brokerage firms, and insurance companies. We find that the impact is positive for all institutions. Bank gains are positively related to size and capitalization. Brokerage firms gain regardless of size, but the gains are inversely related to capitalization and insurance companies gain regardless of size or capital position. The strong positive reaction suggests that the market expects the institutions to benefit from the new opportunities created by the FSMA's passage.  相似文献
