Heat production and storage are positively correlated with measures of body size/composition and heart rate drift during vigorous running     

Buresh R  Berg K  Noble J 《Research quarterly for exercise and sport》2005,76(3):267-274

The purposes of this study were to determine the relationships between: (a) measures of body size/composition and heat production/storage, and (b) heat production/storage and heart rate (HR) drift during running at 95% of the velocity that elicited lactate threshold, which was determined for 20 healthy recreational male runners. Subsequently, changes in skin and tympanic temperatures associated with a vigorous 20-min run, HR, and VO2 data were recorded. It was found that heat production was significantly correlated with body mass (r = .687), lean mass (r = .749), and body surface area (BSA, r = .699). Heat storage was significantly correlated with body mass (r = .519), fat mass (r = .464), and BSA (r = .498). The percentage of produced heat stored was significantly correlated with body mass (r = .427), fat mass (r = .455), and BSA (r = .414). Regression analysis showed that the sum of body mass, percentage of body fat, BSA, lean mass, and fat mass accounted for 30% of the variability in heat storage. It was also found that HR drift was significantly correlated with heat storage (r = .383), percentage of produced heat stored (r = .433), and core temperature change (r = .450). It was concluded that heavier runners experienced greater heat production, heat storage, and core temperature increases than lighter runners during vigorous running.  相似文献   

Initial-link duration and acquisition of preference in concurrent chains     

Berg ME  Grace RC 《Learning & behavior》2006,34(1):50-60

Initial-link response allocation in concurrent chains becomes less extreme as the absolute duration of the initial links increases (Fantino, 1969). The present study asked whether initial-link duration affected how quickly response allocation reached asymptote (i.e., acquisition of preference). Six pigeons were trained on a concurrent-chains procedure in which the terminal links were fixed-interval (FI) 8 sec FI 16 sec or FI 16 sec FI 8 sec and were reversed every 20 sessions. Across conditions, all possible combinations of transitions between variable-interval (VI) 8-sec (short) and VI 24-sec (long) initial-link schedules were studied. Overall, the rate of acquisition was faster when the durations of the initial links preceding the reversal were short rather than long, and when the durations of the initial links following the reversal were long rather than short. By contrast, initial-link duration had no effect on acquisition or asymptotic measures of temporal control of terminal-link responding. These results support the core principle of delay-reduction theory (Fantino, 1969) that the impact of a conditioned reinforcer varies directly with initial-link duration, but also suggest that temporal learning during the terminal links proceeds independently of initial-link duration. nt]mis|These data were presented at the annual meeting of the Association for Behavior Analysis, Boston, May 2004.  相似文献

1265: An examination of some of the management implications of directed time     

Bryan J. Cowan  Nigel Wright 《School Leadership & Management》2013,33(3):301-314

This enquiry seeks to establish how some secondary school headteachers have directed their DEs‐prescribed allocation of 1265 hours. Investigations focus particularly on those management processes used to determine the budget, the measures employed to ensure a flexibility in a budget once it has been defined, and some effects of budgeting on meetings. The allocation of hours to specific school tasks is scrutinized and the authors conclude with recommendations and suggestions for improving budgeting decisions in the future.  相似文献

Dietary Fat Intake and Exercise Among Two- and Four-Year College Students: Differences in Behavior and Psychosocial Factors     

Carla J. Berg  Lawrence C. An  Jasjit S. Ahluwalia 《Community College Journal of Research & Practice》2013,37(5):388-396

Given the demographic differences among two-year colleges and four-year universities and the relatively limited access to health education and campus-based health resources, this study compares the frequency of limiting dietary fat intake and exercising among two- and four-year college students. A total of 2,265 undergraduate students aged 18–25 at a two-year college and a four-year university completed a 108-item online survey in October 2008. We found that two-year college students had less confidence, motivation, and intention to engage in healthy behaviors and reported fewer close friends who exercise regularly but more friends who eat high-fat foods. After controlling for age, gender, ethnicity, and parental education, two-year (versus four-year) college students less frequently limited dietary fat (F(2,2227) = 21.64, p < .001) and less frequently exercised ≥ 20 minutes a day (F(5,2232) = 14.21, p < .001). Thus, research should focus on developing interventions targeting the different psychosocial factors that influence nutrition and exercise among two-year college students.  相似文献

Expression and Reception: An Analytic Method for Assessing Message Production and Consumption in CMC     

Kang Namkoong  Dhavan V. Shah  Bryan McLaughlin  Ming-Yuan Chih  Tae Joon Moon  Shawnika Hull 《Communication methods and measures》2017,11(3):153-172

This article presents an innovative methodology to study computer-mediated communication (CMC), which allows analysis of the multi-layered effects of online expression and reception. The methodology is demonstrated by combining the following three data sets collected from a widely tested eHealth system, the Comprehensive Health Enhancement Support System (CHESS): (1) a flexible and precise computer-aided content analysis; (2) a record of individual message posting and reading; and (3) longitudinal survey data. Further, this article discusses how the resulting data can be applied to online social network analysis and demonstrates how to construct two distinct types of online social networks—open and targeted communication networks—for different types of content embedded in social networks.  相似文献
