AbstractThrough an in-depth, multilevel case study of a professional services firm, this paper illuminates what stakeholders mean when they use the term ‘talent’. The paper underlines how various contextual factors including, workforce composition, ownership structures and individual perceptions influence talent meanings within an organisation. Our analysis of talent phenomena at a multiplicity of levels illustrates that it is not only about the words, phrases, and terms employed when talking about talent that requires examination. There is a need to deliberate on the meanings that underpin the talk because while stakeholders may talk the same way they may mean different things. The paper makes a key theoretical contribution through specific recognition of the importance of thoughtful reflection of how stakeholders discursively construct meanings because ‘talent’ is a concept, which requires translation via talk to become meaningful within the material world and these meanings are influenced by context. Thus, we cannot infer, that talent meanings radiate within organisations, nor across organisational boundaries, industries or countries because discourses arise and materialise within specific contexts and we must acknowledge that talent discourses can not be removed from the context in which they operate. 相似文献

When testing for the equality of two distributions in a case-control design with treatment effects presumed to act possibly
on more than one aspect, different tests may be properly considered for testing for different features of a null hypothesis,
leading to the multiple aspect testing issue. Two different aspects are therefore of interest: the location-aspect, based
on the comparison of location indexes, and the distributional-aspect, based on the comparison of the empirical distribution
functions. A simulation study shows that the combined testing procedure exhibits a good robust overall performance, and an
application in biomedical research is also presented. 相似文献

文章以2004-2005年的上市公司数据为样本,分析了我国财务分析师在预测上市公司未来盈余时影响其预测精确度的主要因素。研究发现,预测机构数量的增加、盈余可预测性以及信息披露质量的提高,将伴随着高的盈余预测精确度,而盈余波动程度越大、公司规模越大,预测的精确度则越低。同时,可预测性、盈余管理、盈余波动以及公司扩张速度对分析师的悲观预测有显著的影响,而可预测性、盈余管理以及公司规模则显著影响分析师对盈余的乐观估计。 相似文献

亏损对上市公司的负面影响非常大,处于亏损边缘或可能微亏的上市公司会通过盈余管理手段来操纵盈利,以避免成为被关注对象或暂停上市或终止上市。本文以我国连亏两年、连亏三年又扭亏的106家上市公司为样本,通过构建模型进行了实证检验,总结出亏损上市公司进行盈余管理的结论并提出建议,以期为证券监管提供经验证据。 相似文献

The methodological ideal of experimentalists, E, is easily stated: derive a testable hypothesis, H, from a well-specified theory, T; implement experiments with a design; implicitly in the latter are auxiliary hypotheses, A, that surface in the review/discussion of completed research reports (payoffs are 'adequate,' Ss are 'relevant,' instructions, context are 'clear,' etc.). We want to be able to conclude, if statistical test outcomes support not-H, that T is 'falsified.' But this is not what we do; rather we ask if there is a flaw in the test, i.e. not-A is supported, and we do more experiments. This is good practice—much better than the statistical rhetoric of falsificationism. Undesigned social processes allow E to accumulate technical and instrumental knowledge that drive the reduction of experimental error and constitute a more coherent methodology than falsificationism. 相似文献

ABSTRACTProspect theory is widely thought to be one of the best-confirmed accounts of human decision-making under risk. There are numerous claims in the literature that various kinds of nonexperimental, observational evidence provide strong support for prospect theory. We investigate the veracity of these claims using a set of philosophy of science morals and a careful delineation of models of choice under risk, focussing on the extant versions of prospect theory and their various components. We challenge the claim that prospect theory is well supported because it explains the equity premium puzzle. In addition, we analyse a major international survey thought to support prospect theory and argue that the support is questionable, both for statistical reasons and because the evidence itself is mixed. Our analyses highlight some important ideas in the philosophy of science and caution against strong claims about support for prospect theory that rely on nonexperimental, observational evidence. 相似文献
