Exploring the Use of Computer Simulation to Evaluate the Implementation of Problem-Solving Consultation     

Markeda Newell PhD 《Journal of educational and psychological consultation》2013,23(3):228-255

The purpose of this study was to examine how school psychologists implemented the problem-solving consultation process within a computer-simulated school environment. Four school psychologists were recruited to complete three simulated consultation cases. The school environment was computer generated and all of the teachers and target students (clients) were computer generated. A qualitative case study design coupled with interviews was used in this study. Three themes emerged from the data analysis including (a) behavioral approach to problem conceptualization, (b) individualized approach to intervention design, and (c) minimal attention to plan evaluation. Implications for problem-solving consultation training as well as use of computer simulation are discussed.  相似文献   

Greening agricultural education at the tertiary level: a case study     

J. Rowe BSc PhD MIEEM 《The Journal of Agricultural Education and Extension》2013,19(3):105-113

Abstract

College curricula are broadening to take into account environmental imperatives, the relatively slow rate of economic and policy change, along with the welter of technical detail which has been generated by agricultural development, militate against successful systematic environmental teaching. This is particularly true within a private institution which must be seen to be serving the immediate needs of the agricultural business community. It is useful in this context to consider the ‘natural environment’ as comprising: the ‘immediate’ countryside, where ‘nature’ functions under differing degrees of managerial constraint; the global environment, where non-sustainable resource use takes its toll; and the environment of the organisation, where ‘environmental soundness’ of practice and products can be assessed. A teaching strategy is suggested where these three ‘environments’ are addressed at the levels of the functional, natural science-based: the societal, embracing legislative and structural responses to pressures; and the level of individual managerial responsibility. The relative emphasis on each element can be adjusted to reflect individual course aims, with modular core teaching networked into allied subject syllabi in a rolling process of adaptation and compromise. The latter should extend to the college’s own activities in land and business management to legitimise the teaching strategy.  相似文献

Campaign Agenda Formation: The News Media in the Korean Congressional Election of 2000     

Young Min PhD 《亚洲交流杂志》2013,23(2):192-204

The present study, as an international application of an agenda-setting model, investigates how campaign agendas of issues are constructed in an election. The Korean Congressional election of 2000 provided rich empirical data for this study; the political party agenda, the civic agenda, and the news agenda were measured in terms of issue salience at two different data points in time during the official campaign period. The results of the cross-lagged rank-order correlations between different agendas indicated the following. First, the party agenda as a whole had little impact on the formation of the news agenda. The party–news relationship, however, showed a different pattern at an individual newspaper level. Specifically, a more conservative newspaper was more susceptible to those parties’ agenda-setting than was its progressive rival. Second, a nationwide civic movement for political reforms slightly influenced the formation of the news agenda, especially that of the reformist newspaper agenda. Both newspapers, on the other hand, substantially influenced the civic campaign's issue emphases. Finally, there existed no significant interactions between the party and the civic agendas.  相似文献   

When Does Self-Affirmation Reduce Negative Responses to Antismoking Messages?     

Xiaoli Nan PhD  Assistant Professor  Xiaoquan Zhao 《Communication Studies》2013,64(4):482-497

Previous research has shown that self-affirmation can reduce individuals’ defensive processing of threatening health messages. In this study, we examine two audience characteristics—smoking experience and trait reactance—that might regulate the effects of self-affirmation on negative message responses within the context of college smoking. Results of a controlled experiment indicate that self-affirmation worked to reduce negative message responses among smokers who were low in trait reactance. For smokers high in trait reactance and nonsmokers, the effect of self-affirmation was either unclear or went in a direction that led to even greater defensive processing.  相似文献

Abstract

The aims of this study were to establish the physical and physiological attributes of elite and sub-elite Malaysian male badminton players and to determine whether these attributes discriminate elite players from sub-elite players. Measurements and tests of basic anthropometry, explosive power, anaerobic recovery capacity, badminton-specific movement agility, maximum strength, and aerobic capacity were conducted on two occasions, separated by at least one day. The elite (n = 12) and sub-elite (n = 12) players' characteristics were, respectively: mean age 24.6 years (s = 3.7) and 20.5 years (s = 0.7); mass 73.2 kg (s = 7.6) and 62.7 kg (s = 4.2); stature 1.76 m (s = 0.07) and 1.71 m (s = 0.05); body fat 12.5% (s = 4.8) and 9.5% (s = 3.4); estimated VO_2max 56.9 ml · kg^?1 · min^?1 (s = 3.7) and 59.5 ml · kg^?1 · min^?1 (s = 5.2). The elite players had greater maximum absolute strength in one-repetition maximum bench press (P = 0.015) compared with the sub-elite players. There were significant differences in instantaneous lower body power estimated from vertical jump height between the elite and sub-elite groups (P < 0.01). However, there was no significant difference between groups in shuttle run tests and on-court badminton-specific movement agility tests. Our results show that elite Malaysian male badminton players are taller, heavier, and stronger than their sub-elite counterparts. The test battery, however, did not allow us to discriminate between the elite and sub-elite players, suggesting that at the elite level tactical knowledge, technical skills, and psychological readiness could be of greater importance.  相似文献

Abstract

Numerous epidemiological investigations have shown that low physical fitness and low physical activity are related to the incidence of coronary artery disease (CAD). Most studies, however, have not examined both variables concurrently to determine which has the strongest association with CAD risk. The purpose of the investigation was to cross-sectionally examine the relationships among physical fitness, physical activity, and risk factors for CAD. Male law enforcement officers (N = 412) from the City of Austin, Texas, were subjects for this study. Physical fitness, physical activity, and risk factors for CAD were assessed through health screenings and from data collected as part of an annual physical fitness assessment. Multivariate analysis of covariance revealed that physical fitness, but not physical activity, was related to several single CAD risk factors. Percent body fat, smoking habits, and Type A behavior score were negatively related to physical fitness level, and high density lipoprotein (HDL) cholesterol was positively related to physical fitness level. Univariate analysis of variance found both physical fitness and physical activity to be significantly related to a composite CAD risk score. Low physical fitness and low physical activity were associated with a high CAD risk score. These data suggest that physical activity must be sufficient to influence physical fitness before statistically significant risk-reducing benefits on single CAD risk factors are obtained, although minimal engagement in weekly vigorous activity provides a significant benefit for the composite CAD risk score. It is plausible, however, that physical fitness is a stronger measure than physical activity and optimally characterizes the relationship among physical activity and CAD risk factors.  相似文献   

Cardiorespiratory and Perceptual Responses to Arm Crank and Wheelchair Exercise Using Various Handrims in Male Paraplegics     

G. William Gayle PhD  Roberta L. Pohlman  Roger M. Glaser  Glen M. Davis 《Research quarterly for exercise and sport》2013,84(3):224-232

Abstract

The purpose of the present study was to determine the effects of 10-in [025–m] versus 16-in [0.41-m] wheelchair handrims on cardiorespiratory and psychophysiological exercise responses during wheelchair propulsion at selected velocities. Fifteen male paraplegics (27.0 ± 5.5 yrs) performed three discontinuous exercise tests (ACE = arm crank ergometer; WERG = wheelchair roller ergometer) and two 1600-m performance-based track trials (TRACK) under simulated race conditions. There were no significant differences in HR, VO₂, V_E, HLa, or category-ratio ratings of perceived exertion (RPE) using different handrims during wheelchair propulsion at 4 km-h¹. In contrast, at 8 km-h^?1 subjects demonstrated a 13% lower steady state VO₂ (p < .05) using the 10-in handrims, coincident with a 23% lower V_E Steady state HR during WERG at 8 km-h^?1 using the 10-in (124.4 ± 39 b.min^?1) or 16-in (130.6 ± 4.6 b.min^?1) handrims were not significantly different. There were also no significant differences between ACE or WERG conditions during maximal effort for VO₂ or V_E. However, HRpeak during ACE was 7% higher than HRpeak during WERG16 (183 ± 15 b.min^?1 vs. 171 ± 12 b.min^?1, p < .05), and whole blood HLa during ACE was also significantly higher (by 2.3-2.5 mmol; p < .05) compared to WERG. There were no significant differences for HR, performance time, or RPE between trials using different handrim diameters during the 1600-m event. In contrast, HLa was significantly lower using smaller handrims (9.9 mmol) compared with larger handrims (11.3 mmol), paralleling a similar difference in the laboratory. Although these data demonstrated few significant differences of physiologic responses between trials using different handrims, there was a tendency for a lower metabolic stress using the smaller handrims.  相似文献   

The Role of Cognitive Appraisal and Friendship Provisions in Adolescents' Affect and Motivation toward Activity in Physical Education     

Susan c. Duncan PhD 《Research quarterly for exercise and sport》2013,84(3):314-323

Abstract

This study investigated the mediational role of affect in the influence of perceived success, causal attributions, and friendship provisions on choice and future expectancies for success and enjoyment, using a multi-sample structural equation modeling approach. Subjects were 422 seventh- and eighth-grade students participating in physical education classes. Higher levels of perceived success, personally controllable attributions, companionship, and esteem support were found to positively influence levels of affect experienced, which in turn enhanced future expectancies for success and enjoyment in physical education and choices to participate in physical activity outside of school. Furthermore, participation experience outside of school influenced, adolescents' perceptions within the physical education setting and their consequent affect and motivation.  相似文献   

Validation of Criterion-Referenced Standards for Tests of Arm and Shoulder Girdle Strength and Endurance     

William J. Rutherford PhD  Charles B. Corbin 《Research quarterly for exercise and sport》2013,84(2):110-119

Abstract

The purpose of this study was to establish criterion-referenced standards for selected tests of arm and shoulder girdle strength and endurance for college females. Several popular tests of arm and shoulder girdle strength and endurance were administered to equal numbers of trained and untrained college females (N = 92) to generate data for the analysis. The contrasting groups method (Berk, 1976; Safrit & Wood, 1990) yielded the following criterion cutoff scores that classified college females as trained or untrained on the basis of regular upper arm and shoulder girdle resistance training: pull-ups = .5 repetitions (reps), 90° push-ups = 16 reps, flexed arm hang = 5s, seated chest press = 24.5 kg, seated biceps curl = 16.4 kg, seated lat pull (latissmus dorsi pull-down) = 38.2 kg, absolute strength index = 86.4 kg, and relative strength index = .6 kg per kg of body weight. Cross-validation of the standards on an independent sample of college females (N = 112) suggested stability of the cutoff scores for pull-ups, flexed arm hang, and relative strength.  相似文献
