The purpose of this study was to assess the effect of the color of light in a room on muscular strength and power. A convenience sample of 18 men (M age = 20.4 yr., SD = 1.2) performed a modified Wingate Anaerobic Cycle Test for muscular power and a hand grip strength test in each of the following conditions: red, blue, and white (neutral) ambient light. A repeated-measures multivariate analysis of variance indicated that average muscular power was significantly higher when performing the test in the room with red light compared to rooms lit with blue light or white light. The results also indicated that grip strength was significantly higher in the room lit with white light as compared to the room lit with blue light.  相似文献

Methods of incorporating a ridge type of regularization into partial redundancy analysis (PRA), constrained redundancy analysis (CRA), and partial and constrained redundancy analysis (PCRA) were discussed. The usefulness of ridge estimation in reducing mean square error (MSE) has been recognized in multiple regression analysis for some time, especially when predictor variables are nearly collinear, and the ordinary least squares estimator is poorly determined. The ridge estimation method was extended to PRA, CRA, and PCRA, where the reduced rank ridge estimates of regression coefficients were obtained by minimizing the ridge least squares criterion. It was shown that in all cases they could be obtained in closed form for a fixed value of ridge parameter. An optimal value of the ridge parameter is found by G-fold cross validation. Illustrative examples were given to demonstrate the usefulness of the method in practical data analysis situations. We thank Jim Ramsay for his insightful comments on an earlier draft of this paper.

This study investigates how the ingratiation and perceived similarity of a job applicant can affect the judgment of an interviewer in determining person–organization fit (P–O fit), hiring recommendations and the job offer during a job interview. Data were collected from 144 interviewers and 184 applicants from 28 companies in Taiwan. The results suggest that applicant ingratiation has a positive effect on an interviewer's perceived similarity with the applicant, and that this perceived similarity mediates the relationship between applicant ingratiation and the interviewer's judgment of the applicant's P–O fit. The results further suggest that the relationship between the interviewer's judgment of the applicant's P–O fit and the job offer is mediated by hiring recommendations. Implications and directions for future research are discussed.  相似文献

The present research examined the moderating influence of situations involving friends and romantic partners on gender differences in interpersonal behaviors reflecting agency and communion. Behavior was studied in three situations varying in social role and dyadic gender composition: same‐sex friendships, opposite‐sex friendships, and romantic relationships. To obtain multiple events representing each relationship situation, participants recorded information about their interpersonal interactions during a 20‐day period using an event‐contingent recording procedure. Results indicated gender differences consistent with gender stereotypes when men and women were interacting with same‐sex friends; men with men were more dominant and women with women were more agreeable. In interactions with romantic partners, gender differences in communal behavior were opposite to gender stereotypes; women were less agreeable and more quarrelsome than men with their romantic partners. Results are considered in reference to developmental socialization theory, social role theory, and studies of gender differences in marital relationships.  相似文献

This paper examines the other side of Enlightenment which privileges the authority and autonomy of reason for human progress and emancipation. It contends that Enlightenment marginalizes and denigrates the categories of (1) body, (2) woman, (3) nature, and (4) non-West which happen to be four central landmarks of postmodern thought.  相似文献

This paper examines the Adventures of Huckleberry Finn in the light of the early Confucian thinker Mencius, arguing in essence that Mencian theories of moral development and self-cultivation can help us to recover the moral significance of Twain's novel. Although ‘ethical criticisms’ of Huckleberry Finn share a long history, I argue that most interpretations have failed to appreciate the moral significance of Jim, either by focusing on the moral arc of Huck in isolation or by casting Jim in one-dimensional terms simply as a symbol or example of human dignity. By invoking the Mencian ideas of ‘moral power’ (de ), human goodness, and the virtues of sympathy and humaneness, this study attempts to bring into relief the many ways that Jim, particularly in his role as an exemplar, functions as an active force in the moral life of Huck. It is hoped that this revised Mencian reading of Huckleberry Finn can restore the moral center of the novel and contribute to the growing discussion on the virtues in moral education.  相似文献

Society considers deception to be an improper act but at the same time, people deceive each other surprisingly often during interpersonal interactions. In our study, this hypocrisy was assumed to be derived from ambivalent attitudes stemming from different sources, which we divided into implicit and explicit. Using a simulated racing task in a virtual environment, we identified participants who chose to be deceptive. Twenty two of the 60 subjects spontaneously decided to cheat in order to gain monetary compensation, while the other 38 subjects chose to be honest. We compared these two groups’ implicit beliefs about deception using the Implicit Association Test (Deception-IAT), as well as their explicit attitudes about deception and their personalities using self-report questionnaires. There was no difference between the two groups in explicit attitude or personality; however, the group who cheated on the racing task showed their implicit preference for deception more than that of the group who acted honestly as measured by the Deception-IAT.  相似文献

Multidimensional measures of body dissatisfaction and disordered eating were studied in samples of 12–15 years old middle school children. Consistent with feminist theories associating body dissatisfaction with rapid social change, Korean girls (n?=?272) exhibited the greatest body dissatisfaction and the most behaviors associated with disordered eating and were followed in order by Korean boys (n?=?276), US girls (n?=?251), and US boys (n?=?220). The results, which replicated Jung and Forbes (2006) report of greater body dissatisfaction among Korean than among US college women, suggest that (1) these differences originate prior to adolescence, and (2) the sociocultural variables producing greater body dissatisfaction in Korean girls and women also influence body dissatisfaction among boys.  相似文献

Questionnaires were sent to 13,549 graduates of four types of proprietary and nonproprietary vocational training programs in four selected metropolitan areas of the United States. Initial responses were received from 5,215 graduates, a response rate of 38.5%. The survey featured an intensive follow-up to reach and estimate the characteristics of the nonrespondent population. Substantial differences favoring nonproprietary programs were found between proprietary and nonproprietary graduates in terms of economic gains following graduation and expressed satisfaction. Nevertheless, both types of programs were found to be generally effective in producing graduates with marketable skills; post-training salaries were high enough to indicate that the training was cost effective in all except proprietary computer training programs. The results supported several recommendations regarding the necessity for uniform standards of accountability in the regulation of vocational training programs, whether they are public or private.  相似文献

The dentate gyrus (DG) is among the few areas in the mammalian brain where production of new neurons continues in the adulthood. Although its functional significance is not completely understood, several lines of evidence suggest the role of DG neurogenesis in learning and memory. Considering that long-term potentiation (LTP) is a prime candidate for the process underlying hippocampal learning and memory, these results raise the possibility that LTP and neurogenesis are closely related. Here, we investigated whether or not LTP induction in the afferent pathway triggers enhanced proliferation of progenitor cells in the DG. LTP was induced by tetanic stimulation in perforant path-DG synapses in one hemisphere, and the number of newly generated progenitor (BrdU-labeled) cells in the DG was quantified. Compared with the control hemisphere (stimulated with low-frequency pulses), the LTP-induced hemisphere contained a significantly higher number of newly generated progenitor cells in the dorsal as well as ventral DG. When CPP, an NMDA receptor antagonist, was administered, tetanic stimulation neither induced LTP nor enhanced progenitor cell proliferation, indicating that NMDA receptor activation, rather than tetanic stimulation per se, is responsible for enhanced progenitor proliferation in the control animal. Our results show that tetanic stimulation of perforant path sufficient to induce LTP increases progenitor proliferation in adult DG in an NMDA receptor-dependent manner.  相似文献
