The development of a fast and reliable Internet, new technologies online payment systems, and changes in work structure that enable and demand flexible working patterns have driven a move to a new form of Internet‐enabled labour exchange called crowdsourcing. Evidence from an in‐depth qualitative study is presented, focusing on selected users' interactions and experiences of working on two UK‐based crowdsourcing platforms. The paper shows that workers engaged in this form of labour exchange need to deploy existing employability skills and networks to effectively meet the challenges, and take advantage of the opportunities, that crowdsourcing presents. Individual factors and circumstances emerge as paramount for workers' continued engagement in this form of employment. Using selected components from an employability framework, the findings suggest that crowdsourcing can offer new pathways to practising skills and enhancing employability for some workers. 相似文献

We examine the capital market pricing implications of firm disclosure opacity as measured by the linguistic readability of REIT annual reports. The SEC has expressed concern that firms selectively manage the transparency of disclosures in order to hide adverse information. After controlling for other non-experimental factors that influence the readability of REIT financial statements, we find (1) financial opacity is negatively related to reported firm performance, and (2) the residual opacity that remains after controlling for other determinants of annual report readability has incremental explanatory power for returns beyond the Fama and French (1992, 1993) risk factors. The opacity risk-return premium persists after controlling for a (heretofore undocumented) stark monotonic decrease in annual report readability following the Sarbanes-Oxley Act of 2002. 相似文献

We investigate how executives, the board, and excess compensation jointly affect the performance of nonprofits. Since the common measure of nonprofit performance often includes salaries, we also use expenses that directly benefit the targeted population. Our results suggest that above average compensation for executives is associated with poor firm performance. However, the negative relation of CEO pay to performance occurs for firms with only one executive, the CEO. We conclude that a powerful CEO with autonomy can harm firm performance, but other executives can mitigate these agency problems. The board also appears to monitor direct community benefits more than indirect benefits. 相似文献

Genetically engineered viruses (GEVs) used as live vaccines are, and will increasingly become, important for prevention of disease in human as well as animal populations. Poxviruses have a number of attractive theoretical and practical advantages as gene expressing vaccine vectors: their large genomes render construction of multivalent vaccines feasible, the vaccines are easy to produce, the virus particles are very thermostable, and inoculation is followed by long‐lasting, protective immune responses. On the other hand, administration and environmental release of GEVs may represent potential unintended harms to human, animal and ecosystem health. We will argue that a strict application of risk‐cost/benefit analyses do not cope appropriately with the current lack of scientific understanding and the complexity of ecosystems that will become GEV recipients, and fail to take into account the deeper ethical groundings that shape the scientific and public opinions. To avoid serious, unintended ecological effects of GEVs, it may be necessary to elaborate the ethical basis for protecting health and the environment. The Precautionary Principle (PP) may provide a basis for adequate consideration of ecological and ethical issues of vital importance to protection of health and environment from unforeseen adverse effects of poxvirus‐vectored vaccines. To operationalise the PP, we suggest that there is a need to identify and systematise lack of scientific understanding, and to acknowledge uncertainty by initiating research with a broad focus involving interdisciplinary research. In this paper we present three main issues related to the employment of the PP: i) identification of scientific uncertainty and its ethical significance in risk assessment and risk management processes, ii) the need for broad risk assessment as a response to scientific uncertainty, and iii) the need for transparency and public involvement to enhance the debate about normative standards concerning acceptability of benefits, risks and uncertainty with regard to GEV use and release. 相似文献

Communication skills are central to intellectual interaction between the providers and the recipients of information. The importance of accounting starts with the gathering and processing of information and ends with the communication of processed information. This paper examines the communication skills which employers, academics and graduate accountants consider necessary to the newly graduated accountant. It also identifies and considers the differences in perception which occur between these groups and suggests solutions to the communication gap. This study confirms findings from previous research that new graduate accountants experience communication-related problems in early employment. In addition, it provides evidence that the Australian accounting curriculum has contributed to the development of communication skills. However, the paper highlights the need for the reconsideration of an emphasis on communication skills in the accounting curriculum, a role which arises from the very nature of accounting as the processing and communication of information. 相似文献
