Academic profession in academic organization   总被引：1，自引：0，他引：1  

Jan-Erik Lane 《Higher Education》1985,14(3):241-268

It has been argued that academic organizations are organized anarchies with ambiguous goal functions and uncertain technologies. Academia cannot evaluate itself because its dynamics is the garbage-can process. The counter-argument is that rational academic man(woman) is a substitute for organizational foolishness. The organizational behavior of academic institutions must be interpreted in terms of the logic of the academic profession.  相似文献   

Developing conceptions of food and nutrition     

Dr Rod Francis  Dr Doug Hill 《Research in Science Education》1993,23(1):77-84

This paper describes an investigation of concepts that various groups hold about food and nutrition. Groups investigated were students in Years 4 and 8, university students in a BEd (primary) program and parents of the Year 4 students. It was found that for many important concepts relating to food selection, the basic ideas of each group were surprisingly consistent, despite the influence of formal education. In particular, misconception about energy and its role in nutrition and particular food groups was an important finding. Implications for school and community education are drawn from the results. Specialization: science curricula.  相似文献

The Influence of Direct and Overheard Messages on Children's Attitudes Toward Novel Social Groups     

Jonathan D. Lane  Emily B. Conder  Joshua Rottman 《Child development》2020,91(3):829-845

Individuals often develop negative biases toward unfamiliar or denigrated groups. Two experimental studies were conducted to investigate the extent to which brief negative messages about novel social groups influence children's (4- to 9-year-olds'; N = 153) intergroup attitudes. The studies examined the relative influence of messages that are provided directly to children versus messages that are overheard and examined whether the force of these messages varies with children's age. According to implicit and explicit measures of children's intergroup attitudes, children rapidly internalized messages demeaning novel groups, thus forming negative attitudes toward outgroups merely on the basis of hearsay. These effects were generally stronger among older children, and were particularly pronounced when the message was provided directly to children.  相似文献

Development and initial validation of an instrument to assess the motivational qualities of music in exercise and sport: the Brunel Music Rating Inventory.   总被引：1，自引：0，他引：1

Equivocal results of the psychophysical effects of music have been explained in part by the insensitivity of researchers to important personal and situational variables when selecting music. The aim of the present study was to operationalize a conceptual framework for the prediction of psychophysical responses to music into a music rating inventory to assess the motivational qualities of music in exercise and sport environments. An initial item pool was developed and administered to 334 aerobics instructors. Exploratory factor analysis produced a 13-item, four-factor structure (association, musicality, cultural impact and rhythm response), which accounted for 59.2% of the variance. This model demonstrated acceptable fit indices when tested using confirmatory factor analysis on 314 exercise-to-music participants, and was better than an alternative two-factor model. When cross-validated using multisample confirmatory factor analysis, the model also showed an acceptable fit overall, although some invariance in the rhythm response factor was evident that can be attributed to the exclusive use of synchronous music by aerobics instructors. The Brunel Music Rating Inventory appears to be a valid and reliable tool for both researchers and practitioners to assess the motivational qualities of music in exercise and sport environments.  相似文献   

Beyond the technical: The role of emotion regulation in lacrosse officiating     

Andrew P. Friesen  Tracey J. Devonport  Andrew M. Lane 《Journal of sports sciences》2017,35(6):579-586

Emotions can influence the performance of referees leading to a need to examine emotions experienced, and regulation strategies used by referees. The present study assessed emotions and emotion regulation strategies of 19 referees officiating at an Under-19 Lacrosse World Championship. Using survey methods and focus group interviews, officials responded to five questions: (a) What emotions were experienced? (b) What events elicited emotions? (c) How did lacrosse officials manage their own emotional states prior to, throughout, and following a competitive game? (d) How did officials manage others’ emotional states? (e) What were the perceived consequences of these strategies? Results indicate that emotions fluctuated throughout the tournament as referees encountered intrapersonal and interpersonal emotion-eliciting events. These fluctuations are suggested to come from a progressively diminished capacity for emotion regulation. Participants used emotion regulation strategies that could be classified into Gross’ (1999) families of emotion regulation strategies, often relying on suppression, emotion contagion, and preventative refereeing. Collectively, the results offer new insights into referee emotion regulation at international events.  相似文献   

Elite tennis player sensitivity to changes in string tension and the effect on resulting ball dynamics     

Rob Bower  Rod Cross 《Sports Engineering》2008,11(1):31-36

Eighteen elite male tennis players were tested to determine their ability to identify string tension differences between rackets strung from 210 N (47 lb) to 285 N (64 lb). Each player impacted four tennis balls projected from a ball machine before changing rackets and repeating the test. Eleven participants (61%) could not correctly detect a 75 N (17 lb) difference between rackets. Only two participants (11%) could correctly detect a 25 N (6 lb) difference. To establish whether varying string tensions affected ball rebound dynamics, the ball’s rebound speed and landing position were analysed. The mean rebound ball speed was 117 km h⁻¹, with only the trials from the 210 N racket producing significantly lower (P < 0.05) rebound speeds than the 235 N and 260 N rackets. This is contrary to previous laboratory-based tests where higher rebound speeds are typically associated with low-string tensions. The anomaly may be attributable to lower swing speeds from participants as they were not familiar with such a low string tension. Ball placement did not appear related to string tension, with the exception of more long errors for the 235 N racket and fewer long errors for the 285 N racket. It was concluded that elite male tennis players display limited ability to detect changes in string tension, impact the ball approximately 6% faster than advanced recreational tennis players during a typical rallying stroke, and that ball placement is predominantly unrelated to string tension for elite performers.  相似文献   

Perceived submaximal force production in young adults     

Jackson AW  Ludtke AW  Martin SB  Koziris LP  Dishman RK 《Research quarterly for exercise and sport》2006,77(1):50-57

The purpose of this investigation was to examine the force production patterns using perceived stimulus cues from 10% to 90% of maximal force. In Experiment 1, 54 men (age: 19-34 years) and 53 women (age: 18-37years) performed leg extensions on a dynamometer at a speed of 60 degrees/s. Participants produced actual forces perceived to be 10-90% of maximal force in 10% increments followed by a maximal force. A 2-min rest interval was maintained between each increment. Participants rested 5 min and repeated the protocol. Desired forces were calculated as the required percentage of the produced maximalforce. In Experiment 2, 40 men (age: 18-30years)followed the protocol ofExperiment 1, but the submaximal stimuli were randomly presented. In Experiment 1, test-retest results indicated consistency between the trials for actual and maximal force (r = .90). The correlations between actual and desired forces were moderately high (r > .76). Actual forces trended above desired forces at 10% of maximal, with median errors ranging 33-40% for men and 60-73% for women. From 30% to 90% of maximal forces, actual trended below desired forces, with median errors ranging from a low of 1.5% to a high of 37%. A power function analysis relating the change in actual force with desired force stimuli produced exponents of 0.68 (.95 CI = 0.62-0.74) for men and 0.5 7 (.95 CI = 0.52-0.62)for women. Findings were similar in Experiment 2, indicating that individuals tended to overshoot and then undershoot desired force production through perceptual force ranges of 10-90% of maximal forces and that force production grew more slowly than perceptual stimulus cues. The results of the present study, along with findings from past research, indicate that production of submaximal force using perceptual cues or stimuli display a great deal of specificity. This specificity is related to type of contraction, amount of muscle mass involved, and number and types of stimuli.  相似文献   

Longitudinal comparisons of wechsler scales in educable mentally handicapped children and adults     

Tony L. Carvajal  J. Melvin Lane  Dennis A. Gay 《Psychology in the schools》1984,21(2):137-140

The change in IQ scores over an extended period of time (approximately 17 years) of subjects who had been placed in classes for the Educable Mentally Handicapped was investigated. Analysis indicated that a significant difference existed between WISC scores administered at the time of initial placement (mean age, 11–9) and WAIS scores administered at a later date (mean age, 17–6). In addition, although a difference was revealed with respect to WAIS scores when the students were divided into two groups based upon initial WISC scores (⩽70 vs. >70), it was determined that the change was in a uniform fashion over time; i.e., neither regression nor interaction effects were detected. A final analysis revealed that those students who were located for a follow-up testing approximately 10 years later (mean age 28–8) continued to show a significant increase in IQ scores. The importance placed upon IQ scores for initial placement of students in EMH programs appears to remain suspect.  相似文献
