Individual assessment involves one psychologist making an assessment of an individual for personnel-related purposes. Individual assessment practice is reviewed, and research on reliability is presented. A study examining the comparability of conclusions reached by consumers is presented. Eighty-six students and thirty-eight managers read nine narrative assessment reports (three of each of three job candidates) and attempted to determine which reports described the same candidate. None of the subjects could correctly group the nine reports; a sizeable proportion did no better than chance in grouping the reports. Implications for assessors and consumers of individual assessments are discussed. 相似文献

We examine intraday execution quality patterns on Nasdaq stocks using proprietary order-level data from a US broker dealer. Orders submitted midday execute slower than orders submitted around the open and close. However, midday orders have lower execution costs. Our results indicate that execution speed and execution cost exhibit offsetting intraday time-dependent patterns and these patterns appear to be induced by variations in informed trading levels. While some traders concentrate their trading activity around the open and close, others prefer to trade midday. Traders have varying preferences for when to trade, and offsetting patterns exist between speed and cost. These factors highlight the complexity in defining an optimal trading time, which, among other things, is dependent on the dimensional preferences of individual traders. 相似文献

At the pinnacles of organizations, comparative tests of unity of command and shared command are nearly impossible because only one individual sits atop most organizations. In organizations led by co‐CEOs, however, such a test is possible because co‐CEOs can truly share power. But do they? Our research pits the unity‐of‐command principle against the shared‐command principle and finds overall support for the former, even within the co‐CEO context. Our sample of 71 co‐CEO pairs at publicly traded U.S. firms shows that increasing power gaps between co‐CEOs are positively associated with firm performance. This positive association wanes and turns negative, however, as power gaps become very large. We conclude that whatever benefits the co‐CEO structure might offer likely lie outside the shared command paradigm. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

More than ever, corporations are expected to practice “citizenship” by engaging in various community or social philanthropy programs. These corporate social responsibility (CSR) programs have broad appeal among business scholars, business executives, and the public. After first setting some theoretical boundaries for CSR as it relates to the legal and strategic management fields, the authors examine how CSR (both its implementation and expectations) can lead to unintended results, compromising the distinct roles business and government play in market-driven, democratic systems. 相似文献

Maori retained high levels of self determination under the Treaty of Waitangi in 1840, although much of the subsequent history of the 19th century involved attempts both formal and informal by the colonial powers to subvert the Act. Therefore, while tourism has brought significant economic advantages for some tribes (iwi), and promises economic returns for others, Maori are insistent that they retain control over the process. The paper describes some of the significant impacts of tourism on Maori culture, but it is concluded that the truths of tourist impacts are plural, and can only be understood within an understanding of Maori cosmology. As such, Maori are adept at distinguishing between the signs and symbols of tourist artifacts. 相似文献

Both the lack of market data and the need to adopt a more holistic approach in the valuation of non‐market activities within health care have pointed towards the use of contingent valuation (CV) methods. However, to date, few studies have employed such techniques to value informal care, despite its provision being an important public policy question. We propose an analytical framework that through the use of random parameters models and respondents' certainty scales can incorporate both unobserved and observed heterogeneity in the CV modelling. This is the first CV study of informal care for Scotland (UK) and a £7.68 per hour value is estimated. 相似文献
