The use of higher-order multidimensional constructs (i.e., latent constructs comprised of standalone variables) in the organizational
psychology and behavior literatures is becoming commonplace. Despite their advantages (e.g., greater parsimony and bandwidth),
the development and validation of such constructs often unfolds in an indiscriminant fashion. It is not surprising, then,
that much debate has arisen regarding the viability of many higher-order constructs. In this article, we outline ten recommendations
for improving the construct- and criterion-related validity of higher-order constructs. Chief among these recommendations
include the need for researchers to specify precise theoretical and empirical inclusion criteria, to rule out alternative
explanations for the emergence of a higher-order factor and to assess incremental and relative importance. To illustrate how
these recommendations play out, we apply them to core self-evaluation as an example. We believe that higher-order constructs
may offer unique insight into work-relevant phenomena, provided they are established via rigorous means. 相似文献

Parent and teen MySpace user pairs completed online surveys administered in June (N = 266) and September 2006 (N = 341) to assess relationships between parenting styles and limit setting and monitoring of online behaviors, the prevalence of Internet dangers and pre-teen and teen MySpace behaviors. Cross-comparison measures of MySpace usage, parenting style, limit setting/monitoring, MySpace problems, and media perceptions were used. Parenting styles were strongly related to adolescent MySpace experiences, behaviors, and attitudes, with some age differences. Parents with older children were more likely to have Neglectful or Indulgent parenting styles and less likely to set limits on online behavior. The extent of sexual solicitation, pornography, and cyberbullying was relatively low as compared with studies asserting a high incidence of Internet-related problems. Parents' high estimates of online dangers were not matched by their low rates of setting limits and monitoring teens. Theoretical and practical perspectives of the results are offered to enhance social networking experiences for parents and their children. 相似文献

Nonhuman animals, like humans, appear sensitive to the structure of the elements of sequences, perhaps even when the structure relates nonadjacent elements. In the present study, we examined the contribution of chunking, rule learning, and item memory when rats learned serial patterns composed of two interleaved subpatterns. In one group, the first interleaved subpattern was a formally simple sequence, whereas in two other groups the first subpattern was formally more complex, containing 2 or 4 violation elements, respectively. In all groups, the second interleaved subpattern encountered was formally simple. Evidence from the study suggests that rats chunked their interleaved patterns into component subpatterns, that is, they cognitively sorted pattern elements to form chunks based on nonadjacent structural relationships that can be characterized as rules. They also learned interitem associations via traditional discrimination learning to use adjacent elements as compound or configural cues for later events in the sequence. Thus, the evidence suggests that rats used chunking, rule learning, and interitem association learning concurrently to master these complex patterns. 相似文献

A multilevel model of leadership, empowerment, and performance was tested using a sample of 62 teams, 445 individual members, 62 team leaders, and 31 external managers from 31 stores of a Fortune 500 company. Leader-member exchange and leadership climate related differently to individual and team empowerment and interacted to influence individual empowerment. Also, several relationships were supported in more but not in less interdependent teams. Specifically, leader-member exchange related to individual performance partially through individual empowerment; leadership climate related to team performance partially through team empowerment; team empowerment moderated the relationship between individual empowerment and performance; and individual performance was positively related to team performance. Contributions to team leadership theory, research, and practices are discussed. 相似文献

According to Parfit, the best version of Kantian ethics takes as its central principle Kantian Contractualism: the thesis that everyone ought to follow the principles whose universal acceptance everyone could rationally will. This paper examines that thesis, identifies a class of annoying counterexamples, and suggests that when Kantian Contractualism is modified in response to these examples, the resulting principle is too complex and ad hoc to serve as the 'supreme principle of morality'. 相似文献

The number of individuals receiving genetic counseling for hereditary breast and ovarian cancer syndrome has steadily risen.
To triage patients for genetic counseling and to help reduce the amount of time needed by a genetic counselor in direct patient
contact, many clinics have implemented the use of family history questionnaires. Although such questionnaires are widely used,
scant literature exists evaluating their effectiveness. This article explores the extent to which family history questionnaires
are being used in Ontario and addresses the utility of such questionnaires in one familial cancer clinic. By comparing the
pedigrees created from questionnaires to those updated during genetic counseling, the accuracy and effectiveness of the questionnaires
was explored. Of 121 families recruited into the study, 12% acquired changes to their pedigree that led to a revised probability
estimate for having a BRCA1 or BRCA2 mutation and 5% acquired changes that altered their eligibility for genetic testing.
No statistically significant difference existed between the eligibility for genetic testing prior to and post counseling.
This suggests that family history questionnaires can be effective at obtaining a family history and accurately assessing eligibility
for genetic testing. Based on the variables that were significantly associated with a change in probability estimate, we further
present recommendations for improving the clarity of such questionnaires and therefore the ease of use by patients. 相似文献
