Exploring Applicant Pool Quantity and Quality: The Effects of Early Recruitment Practice Strategies, Corporate Advertising, and Firm Reputation 总被引:2,自引:0,他引:2
Drawing on marketing and recruitment theory, we examined relationships among early recruitment practices, organizational factors, and organization-level recruitment outcomes, predicting that low-involvement recruitment practices, high-involvement recruitment practices, corporate advertising, and firm reputation would positively affect the quantity and quality of organizations' applicant pools. We also predicted that corporate advertising and firm reputation would moderate the effects of the 2 recruitment strategies. Data for 99 organizations collected from multiple sources provided some evidence that early recruitment practices, corporate advertising, and firm reputation each had direct effects on applicant pool quantity and quality. More importantly, we found that low-involvement recruitment practices were more effective for firms with relatively low levels of corporate advertising and firm reputation, whereas high-involvement recruitment practices were more effective for firms with relatively high levels of advertising and reputation. 相似文献

Rules of thumb for power in multiple regression research abound. Most such rules dictate the necessary sample size, but they are based only upon the number of predictor variables, usually ignoring other critical factors necessary to compute power accurately. Other guides to power in multiple regression typically use approximate rather than precise equations for the underlying distribution; entail complex preparatory computations; require interpolation with tabular presentation formats; run only under software such as Mathmatica or SAS that may not be immediately available to the user; or are sold to the user as parts of power computation packages. In contrast, the program we offer herein is immediately downloadable at no charge, runs under Windows, is interactive, self-explanatory, flexible to fit the user's own regression problems, and is as accurate as single precision computation ordinarily permits. 相似文献

针对Manens和WolterS(2002)关于内插材料加工对内隐记忆的影响的研究设计中没有考虑到内插材料与目标词语义特征匹配这一条件,通过实验证实了,与目标词有不同特征匹配的内插材料加工对目标词线索提取的内隐记忆有着不同影响:可能没有影响,可能干扰也可能促进。在不同学习加工类型和不同测验类型条件下,内插材料对内隐记忆的影响将可能表现出更加复杂的情况。 相似文献

If modernity is manifested as essentialism, postmodernity is manifested as anti-essentialism. Modernity is, in essence, human
beings’ discovery of their own power, and is based on rational knowledge that has grasped the essence of things. In fact,
in the discourse system of modernity, the various concepts of “essence” connote nothing but people’s imaginative constructions
and rational conjectures about objects. In the past, our order, be it internal or external, was in essence guaranteed by God.
Afterwards, all “essences”, as essences, must rationally prove the reason for their existence. In the postmodern context and
discourse system, God, and also the “human being” who has created essence, has “died”. We should not simply resume the belief
in traditional essence, but should reconstruct, on the basis of a full understanding of the intellectual meaning of postmodernity’s
challenges, some historicity, practicality, and the concept of essence that accords with the historical as well as communicative
rationality. We must realize that the essence of things is the essence of particular things in a particular stage of development,
internally containing infinite differences and variety. Only things with postmodern traits contain modernity, and only the
concept of essence that conceives difference accords with time. 相似文献

On the basis of several reviews of the literature, Lynn [Lynn, R., (2006). Race differences in intelligence: An evolutionary analysis. Augusta, GA: Washington Summit Publishers.] and Lynn and Vanhanen [Lynn, R., & Vanhanen, T., (2006). IQ and global inequality. Augusta, GA: Washington Summit Publishers.] concluded that the average IQ of the Black population of sub-Saharan Africa lies below 70. In this paper, the authors systematically review published empirical data on the performance of Africans on the following IQ tests: Draw-A-Man (DAM) test, Kaufman-Assessment Battery for Children (K-ABC), the Wechsler scales (WAIS & WISC), and several other IQ tests (but not the Raven's tests). Inclusion and exclusion criteria are explicitly discussed. Results show that average IQ of Africans on these tests is approximately 82 when compared to UK norms. We provide estimates of the average IQ per country and estimates on the basis of alternative inclusion criteria. Our estimate of average IQ converges with the finding that national IQs of sub-Saharan African countries as predicted from several international studies of student achievement are around 82. It is suggested that this estimate should be considered in light of the Flynn Effect. It is concluded that more psychometric studies are needed to address the issue of measurement bias of western IQ tests for Africans. 相似文献
