The use of performance-enhancing drugs (PED), also known as “doping,” is a common practice among professional athletes in Iran and this global phenomenon is a serious social problem. The main purpose of this research is to test the efficacy of Gottfredson and Hirschi’s conceptualization of low self-control in conjunction with their ideas of effective parenting and rational choice, in explaining why athletes engage in doping activity. Using self-report data from a random sample of 606 professional athletes from Rasht, Iran, the current study indicates that there are significant associations between ineffective parenting, self-control, perceived costs, and doping activity. 相似文献

This study investigated current attitudes towards HIV prevention in a sample of 1061 college students enrolled at a midwestern university. The survey was a self-administered set of 8 demographic questions and 15 questions about attitudes. The findings indicated sex difference in overall attitudes, with females having more positive attitudes than male peers with regard to HIV prevention. Also, analysis of variance indicated ethnicity was related to overall attitudes toward HIV prevention. It appears that education which might reduce the prevalence of HIV infection should consider programs specific to sex and ethnicity. 相似文献

The authors investigated the post-traumatic stress disorder (PTSD) symptoms of young adolescents who had been directly involved in a disaster in Tehran. The participants were 19 chlidren who had survived a boat sinking in Tehran's city park in 2002. By using the Post-Traumatic Stress Disorder Symptom Scale (PSS; E. B. Foa, D. S. Riggs, C. V. Dancu, & B. O. Rothbaum, 1993) as well as a clinical interview based on the definition cited in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV; American Psychiatric Association, 1994, p. 424), 16 participants (84.2%) were diagnosed with PTSD using the PSS and 17 (89.5%) were diagnosed with PTSD using the psychiatric interview. 相似文献

In the present study, the efficacy of visual demonstrations and verbal instructions as instructional constraints on the acquisition of movement coordination was investigated. Fifteen participants performed an aiming task on 100 acquisition and 20 retention trials, under 1 of 3 conditions: a modeling group (MG), a verbally directed group (VDG), and a control group (CG). The MG observed a model intermittently throughout acquisition, whereas the VDG was verbally instructed to use the model's movement pattern. Participants in the CG received neither form of instruction. Kinematic analysis revealed that compared with verbal instructions or no instructions, visual demonstrations significantly improved participants' approximation of the model's coordination pattern. No differences were found in movement outcomes. Coordination data supported the visual perception perspective on observational learning, whereas outcome data suggested that the modeling effect is mainly a function of task constraints, that is, the novelty of a movement pattern. 相似文献

The stressing action of a medium-intensity, magnetostatic field was studied for several levels of intensity. Our purpose was (a) to verify a stressing action by display of the general adaptation syndrome Pattern on the growth rate of mice and (b) to establish the relation between effect and field intensity on the same variable. Eight groups of mice showed a linear relation. Moreover, stressing action was noticed at lower intensities than previously suggested. 相似文献

Given the importance associated with multiple-document literacy in the present-day knowledge societies and the dearth of research in English Language Teaching in general and English for Specific/Academic Purposes (ESAP) contexts in particular on multiple-document comprehension and the significance of reader beliefs in this type of comprehension, the present study was carried out with the aim of investigating the relationship between ESAP students’ personal epistemological beliefs and their inferential intratextual and intertextual understanding of multiple texts. To this aim, 64 first-semester midwifery students were selected as the participants of the study. They were required to read four passages on multi-fetal pregnancy which discussed different aspects of this phenomenon. Having filled out the Epistemological Beliefs Inventory, they were tested on the inferential intratextual and intertextual comprehension of the texts. Results of the analyses of the data revealed significant associations between epistemological beliefs and the inferential comprehension of multiple texts. The results also indicated the poorer performance of the participants in intertextual inferential understanding of the texts compared with the intratextual understanding of them. The study concludes with tentative implication of the findings for ESAP reading courses. 相似文献

The construction of social identity is an interdisciplinary term, which is a favourite topic for many scholars worldwide. Religion and identity are intertwined regarding the concept of identity construction. In Iran, this relation can best be seen through English as a Foreign Language (EFL) textbooks. To achieve this, this study investigates the depiction of men and women within Iranian high school EFL textbooks, tested against Islamic custom, utilizing linear and nonlinear approaches. Or, to put it another way, the content and pictures of these textbooks were tested with regards to Islamic customs. Finally, the concept of nationhood and identity were elaborated upon, regarding religious content in the EFL high school textbooks of Iran. 相似文献
