Two studies were conducted to assess the effects of rapid eye movement (REM) sleep deprivation on shock-elicited aggression. REM deprivation periods of 0, 24, 48, and 72 h were used in the first study, while 48-, 72-, 96-, and 120-h periods were used in the second study. Both studies indicated that increases in REM deprivation (up to 96 h) resulted in increases in the number of aggressive responses. A decrease was shown by the 120-h group. A drive-energization or motivational-effects model is suggested.  相似文献

The purpose of this simulation study was to assess the performance of latent variable models that take into account the complex sampling mechanism that often underlies data used in educational, psychological, and other social science research. Analyses were conducted using the multiple indicator multiple cause (MIMIC) model, which is a flexible and effective tool for relating observed and latent variables. The data were simulated in a hierarchical framework (e.g., individuals nested in schools) so that a multilevel modeling approach would be appropriate. Analyses were conducted accounting for and not accounting for the nested data to determine the impact of ignoring such multilevel data structures in full structural equation models. Results highlight the differences in modeling results when the analytic strategy is congruent with the data structure and what occurs when this congruency is absent. Type I error rates and power for the standard and multilevel methods were similar for within-cluster variables and for the multilevel model with between-cluster variables. However, Type I error rates were inflated for the standard approach when modeling between-cluster variables.  相似文献

A number of reports of the use of time analysis systems as a basis of self‐evaluation is available. This article provides data collected over a year by a head of department performing a lecturer's role. While of value as a means of self evaluation, the data raises some major issues in terms of the management of departments in general and of those in the public sector of higher eduction in England and Wales in particular. The implications in relation to presumed conditions of service and to the elaboration of the role of the lecturer with the growth in demands for accountability and participation in decision‐making are examined.  相似文献

Rural hospitals face difficult times as Medicare health insurance threatens their survival. A small community in Polk County, North Carolina, developed a program that was designed to take advantage of the Medicare skilled nursing benefit as a payment source and which can be implemented by any rural hospital that has Medicare-certified swing beds or distinct nursing facilities. This program involves the development of a special unit, the Restorative Care Unit (RCU), which provides subacute care to older adults. A major element in the RCU care system is a highly structured continuing education program for hospital staff. The continuing education component trains personnel to implement and manage the RCU care system using a team approach. The Appalachian Geriatric Education Center Consortium recognized the need for dissemination of this model of service. They took the concept, developed a curriculum and implemented it with eight rural hospitals. The purpose of this article is to describe in detail the RCU care system continuing education element, and present results from a qualitative and quantitative evaluation of the program. The stages of the development of the program are described, in addition to the content of the curriculum.  相似文献

Photovoice, a participatory action research method, supports deep, personal reflection through the use of photography, personal narrative development, and group discussion. This lesson plan describes the use of Photovoice as a pedagogical tool in an undergraduate human sexuality course. The goal of this activity is to encourage students to 1) think beyond the texts presented in class, 2) make critical connections to their own lived experience and community context, and 3) deepen reflection through sharing and discussing with others. The lesson plan describes the process of bringing Photovoice into the classroom as well as student insights on the activity.  相似文献

Techniques of presenting information temporally in the auditory and visual modalities and spatially in the visual modality were used to assess information processing in 7- and 9-year-old children. The results of the study were interpreted as contradictory to the view that modalities are specialized for the processing of distinct forms of information. Viewed developmentally with related literature, however, the study also suggests that some specialization of modalities may be found in the preschool years, with a school-age shift to nonspecialization.  相似文献

Despite some controversy, there is an emerging body of knowledge regarding the nature, prevalence, assessment, and treatment of childhood depression. The following study was undertaken to determine how this knowledge compares with the perceptions and practices of school psychologists in two north central states. A need for school psychologists to define the concept of childhood depression is identified. Use of DSM III-R for the diagnosis of childhood depression in the schools and the inclusion of standardized measurement techniques in the assessment process are advocated. Involvement of school psychologists in the treatment process, either directly or indirectly, is also recommended.  相似文献
