The purpose of this investigation was to identify the extent to which college students' self-reports of their in-class participation are related to their impressions of instructors (i.e., credibility, attractiveness, and homophily). Participants were 223 undergraduate students enrolled in an introductory communication course at a large Mid-Atlantic university. Students' self-reports of their in-class participation were positively correlated with perceived instructor social attractiveness, physical attractiveness, background homophily, and attititude homophily, but not with perceived instructor competence, character, caring, and task attractiveness. Furthermore, class size, perceived instructor social attractiveness, and perceived instructor background homophily emerged as significant predictors of in-class participation. 相似文献

This content analysis examined framing and second-level agenda setting in U.S. newspaper pre-election coverage of the 2006 Mexican presidential elections and the new Mexican expatriate voting law. The authors conducted a quantitative analysis of 161 articles and a qualitative analysis of 36 articles in U.S. newspapers from August 2005 through mid-April 2006. Findings indicated that Andrés Manuel López Obrador received more coverage (59.6%) than Roberto Madrazo (27.8%) or the eventual winner, Felipe Calderón (29.1%). Candidate attributes were highlighted more than Mexican domestic or Mexico–U.S. issues. The dominant procedural frame was the election horse race. The main substantive frames were the election as an extension of U.S.–Mexico economic relations and the election as an extension of Latin American leftist/populist movements. The expatriate voting law was characterized as unsuccessful and blamed on apathetic voters, the Mexican government's faulty implementation, and a corrupt system. 相似文献

This study examined the credibility implications of employees who date at work. A 2 (status dynamic of the romance) × 2 (sex of the peer) design was used to examine effects of workplace romance on perceptions of credibility. One hundred and forty full-time working adults assessed the credibility of a hypothetical coworker who was involved in a workplace romance. Results indicate that peers who date superiors are viewed as less caring and less trustworthy than are peers who date equal status employees. Sex and status interacted such that women dating superiors versus peers were perceived as less caring and less trustworthy, whereas perceptions of men did not differ based on the status of their relational partners. Limitations and future research are discussed. 相似文献

This study investigated how educational experiences between community college transfer students and native students differed at a four-year institution. The study sample included groups of native students and community college transfer students, who were further divided by timing of matriculation to the study institution. Benchmarks from National Survey of Student Engagement (NSSE) were used to assess the levels of students' collegiate experiences. After controlling for various explanatory variables, timing of matriculation to the senior institution showed significant differences in student engagement. Moreover, enrollment status, such as full- and part-time presented the largest effects on the levels of students' educational involvement regardless of student type. 相似文献

In this study we examined the performance during, and the physiological and metabolic responses to, prolonged, intermittent, high-intensity shuttle running in hot (~30 C, dry bulb temperature) and moderate (~20 C) environmental conditions. Twelve male students, whose mean (s x ) age, body mass and maximal oxygen uptake (V O 2m ax ) were 22 ± 1 years, 69.8 ± 01.8 kg and 56.9 ± 1.1 ml . kg ?1 . min ?1 respectively, performed intermittent high- and low-speed running involving five sets of ~15 min of repeated cycles of walking and variable speed running followed by 60 s run/rest exercise until fatigue. The total distance completed in the hot and moderate trials was 8842 3790 m and 11,280 214 m respectively (P < 0.01). This decrement in performance occurred even though no differences existed in the level of dehydration, rating of perceived exertion, blood glucose and lactate, plasma free fatty acid and ammonia concentrations between the two trials. However, water consumption was almost twice as great in the hot trial (hot vs moderate: 1.18 ± 0.12 vs 0.63 ± 0.07 l . h ?1 , P < 0.01). Rectal temperature (hot vs moderate: 39.4 ± 0.1 vs 38.0 ± 0.1 C, P < 0.01) and heart rate (hot vs moderate: 186 ± 2 vs 179 ± 2 beats . min ?1 , P < 0.05) were higher at the end of the hot condition than at the same point in time in the moderate condition. The correlation between the rate of rise in rectal temperature and the distance completed during the hot condition was -0.94 (P < 0.01); for the moderate condition it was -0.65 (P <0.05). The reduced performance in the hot condition was associated with high body temperature; the precise mechanisms by which the performance decrement was brought about are, however, unclear. 相似文献

Abstract The potential for imprecision in the estimation of hydration status from changes in body mass has been outlined previously but the equations derived from these derivations appear inconsistent. Reconciliation of body mass loss in terms of sweat loss and effective body water loss is possible from specific equation sets provided that gains and losses of both body mass and water used in the derivation of sweat loss and to derive effective body water loss are in inclusive equation sets. This is obligatory so that mass and water changes as quantifiable determinants are consistent with both internal processes and external gains and losses. Thus, body mass loss, substrate oxidation, metabolic water, and all the terms used in simultaneous equation sets have to be reconciled not only as identical variables but mathematically balance exactly. The revised equation for effective body water loss given here is different from that originally proposed. Metabolic water is part of body mass loss corrected for substrate oxidation, fluid ingestion, and respiratory water to derive sweat loss and it may not be justified to also include water associated with glycogen as releasable bound water. Accordingly, our calculated effective body water loss is substantially a greater loss than originally supposed but clearly still less than the simple balance between mass loss and fluid ingested. 相似文献

Pádraig Hogan 《Educational theory》2013,63(3):237-252
The notion of competencies has been a familiar feature of educational reform policies for decades. In this essay, Pádraig Hogan begins by highlighting the contrasting notion of capabilities, pioneered by the research of Amartya Sen and Martha Nussbaum. An educational variant of the notion of capabilities then becomes the basis for exploring venturesome environments of learning: environments that are hospitable to the cultivation of such capabilities among students and their teachers. In this exploration Hogan emphasizes disclosing the kinds of relations that constitute such environments. In particular, he identifies four kinds of relations and investigates the interplay among them. In the second part of the essay, Hogan reviews an ongoing research project in Ireland that has been promoting such environments in postprimary education: Teaching and Learning for the 21st Century. Although the project avoids proffering universal claims about “what works,” its rationale and conduct nevertheless call policymakers' attention to what has worked and to the reasons why. 相似文献

This paper reports the results of two studies. The purpose of the first study was to determine if lifestyle variables and past involvement in physical activity was related to current activity levels in master athletes and sedentary older adults. Retrospective interviews were conducted with 12 master athletes and 12 sedentary older adults. Results demonstrated that education level, spouse participation, smoking, and recent physical activity levels were indicators of current involvement. The second study investigated the reliability of the data collected in the retrospective interviews. Similar to results with younger samples, we confirm that lifestyle variables and physical activity involvement could be accurately recalled for a period of 25 years, making this tool a useful addition for the study of physical activity in older adults. 相似文献
