The present paper examines whether organizational survey response behavior relates to organizational citizenship behavior (OCB). In Study 1, we examined the relationship between OCB dimensions and survey completion intentions in a field setting (n=228). In Study 2, we compared respondents and different groups of nonrespondents on OCB dimensions using an experimental design in a university setting (n=622). Survey response and OCBs were found to be related. OCB research may suffer from nonresponse bias, with organizational surveys failing to capture the opinions of those least likely to engage in OCBs.  相似文献

This study examines changes in the characteristics of the homeless population before and after a period of extended economic expansion (1992–2002). Data from other sources suggest that, during this 10-year period, the size of the overall population of homeless persons may have declined slightly, though not significantly, both in the city studied and nationally. In-depth surveys of representative samples of homeless adults (N = 249 in 1992–94; N = 220 in 2000–2002) revealed significant differences in the composition of the homeless population across the time period, consistent with queuing theory. Persons experiencing homelessness after the expansion appeared to be a more “chronic,” less readily employable population than those interviewed at the start of the expansion: Those interviewed after were older, spent more time living on the streets, had more health symptoms, were more likely to have a diagnosis of schizophrenia, and had more restricted social networks and social support. Policy, research, and service provision implications of the findings are discussed.  相似文献

The ability to transfer learning across contexts is an adaptive skill that develops rapidly during early childhood. Learning from television is a specific instance of transfer of learning between a two-dimensional (2D) representation and a three-dimensional (3D) object. Understanding the conditions under which young children might accomplish this particular kind of transfer is important because by 2 years of age 90% of US children are viewing television on a daily basis. Recent research shows that children can imitate actions presented on television using the corresponding real-world objects, but this same research also shows that children learn less from television than they do from live demonstrations until they are at least 3 years old; termed the video deficit effect. At present, there is no coherent theory to account for the video deficit effect; how learning is disrupted by this change in context is poorly understood. The aims of the present review are: (1) to review the conditions under which children transfer learning between 2D images and 3D objects during early childhood and (2) to integrate developmental theories of memory processing into the transfer of learning from media literature using Hayne’s (2004) developmental representational flexibility account. The review will conclude that studies on the transfer of learning between 2D and 3D sources have important theoretical implications for general developmental theories of cognitive development, and in particular the development of a flexible representational system, as well as policy implications for early education regarding the potential use and limitations of media as effective teaching tools during early childhood.  相似文献

In an article in the Journal of Philosophical Logic in 1996, “Towards a Model Theory of Venn Diagrams,” (Vol. 25, No. 5, pp. 463–482), Hammer and Danner proved the full completeness of Shin’s formal system for reasoning with Venn Diagrams. Their proof is eight pages long. This note gives a brief five line proof of this same result, using connections between diagrammatic and sentential representations.  相似文献

Three shadowing experiments investigated the hypothesis that difficulties in concentration are caused by internal factors as well as by the novelty, intensity or salience of background events. On the last trial of each experiment, a background message, which subjects had been instructed to ignore, changed unexpectedly. Most subjects noticed these changes and were disrupted by them (Experiments 1, 2 and 3). A smaller number of “concentrators” reported that they were unaware the changes had taken place. These concentrators were less disrupted by the background message than the non-concentrators both on the last trial and on earlier dichotic trials (Experiments 1 and 3). However, even concentrators were momentarily disrupted by the background changes (Experiment 3). Increased attended task difficulty increases the likelihood that subjects will fail to notice the changes (Experiment 2). The results support the view that good concentration consists in the ability to keep distracting events from consciousness.  相似文献

Self‐forgiveness is associated with psychological and relational well‐being and may be a worthwhile treatment goal for clients who have hurt others. The authors utilized theoretical and empirical literature to describe a 4‐component therapeutic model of self‐forgiveness—responsibility, remorse, restoration, and renewal—and offer suggestions for promoting each component with clients. Finally, the authors explore potential contraindications and the applicability of self‐forgiveness for military veterans, clients in substance abuse treatment, and clients convicted of a crime.  相似文献

This study sought to determine changes in 121 White counseling students following their participation in an experiential, race‐based course taught in a group format. Pre‐ and postoutcomes were reported based on instruments that measured White racial identity development, White privilege, color blindness, and the costs of racism. Findings indicated significant changes according to the majority of measures, although with certain distinctions. Findings are discussed in light of the current literature. Este estudio trató de determinar los cambios en 121 estudiantes blancos de consejería después de su participación en un curso experiencial basado en la raza que se enseñó en formato de grupo. Se comunicaron los resultados previos y posteriores basándose en instrumentos que midieron el desarrollo de la identidad racial blanca, el privilegio blanco, la falta de percepción de color y los costos del racismo. Los hallazgos indicaron cambios significativos según la mayoría de mediciones, aunque con ciertas distinciones. Se discuten los hallazgos a la luz de las investigaciones actuales.  相似文献

Living donor lung (lobar) transplantation has greatly decreased in the past decade due to the success of the lung allocation score (LAS) system, instituted in 2005 by the Organ Procurement and Transplantation Network (OPTN). Between 1993 and 2006, 460 living lung donor transplants were performed in the United States with 369 donations occurring at the University of Southern California and Washington University in St. Louis. These two centers accounted for over 80% of all living donor lung transplants between 1994 and 2006. All potential donors received a psychological/psychiatric evaluation as part of the donor selection process, which is standard practice in the United States, Europe, and Asia. Utilized and non-utilized lung donors were compared in terms of their psychiatric history and present status. Results indicated that 31% (N?=?54) of the total sample had a lifetime prevalence of a psychiatric disorder, which is less than that the 46% lifetime rate for the general population (Kessler in Arch Gen Psychiatry 62:593–602, 2005). This study did find that psychiatric history or status was not exclusion factor for transplant surgery in either group. This observation about psychiatric issues in potential living lung donors should be useful to transplant centers who utilize adult live donors of any solid organ type for pediatric recipients and in Japan where live donor lung transplants still represent a significant proportion of lung transplants (Date in J Thorac Dis 8: S631–S636, 2016).
