Counselor Education on Lesbian,Gay, and Bisexual Issues: Comparing Information and Attitude Exploration     

Tania Israel  Gail Hackett 《Counselor Education & Supervision》2004,43(3):179-191

The authors compared the effects of information‐based and attitude‐based interventions on counselor trainees' knowledge about and attitudes toward lesbian, gay, and bisexual clients. Analyses of variance indicated that providing information yielded higher knowledge levels than did not providing information and that the exploration of attitudes led to reporting more negative attitudes than did not exploring attitudes. The implications of the findings for counselor education and future research are discussed.  相似文献   

Discriminative control of interspecific killing in hungry and satiated rats     

Israel Posner  William M. Miley 《Learning & behavior》1982,10(2):141-144

Hungry and satiated killer Long-Evans rats were exposed to two species of prey, mice and frogs. Experiment 1 demonstrated that the rats learned to discriminate between prey when attacks upon one of the prey were punished by electric shocks and attacks upon the alternative were not punished. Thus, killing of the “dangerous” prey was suppressed, while killing of the alternative, “safe” prey continued. However, in Experiment 2—in which the consequences of killing the prey differed in that one was allowed to be eaten following a kill but the other was not—no evidence of discriminative attack resulted. Hungry and satiated rats did not differ in their responsiveness toward prey as objects of attack, but hungry killers were more responsive to prey as food, thus demonstrating a dissociation of killing and eating control.  相似文献

Swimming Between: An examination of the Inherent Complexity within Social Justice     

Israel Aguilar  Sarah Nelson  Juan Manuel Niño 《The Teacher Educator》2013,48(3):250-265

Classrooms tend to be absolute spaces, places where fluidity is rejected and nearly everything—from people, to ideas, to practices and policies—is viewed and organized through binary logic. Because binary logic is implicitly accepted as the natural order in schools and the structures resulting from it are highly unmalleable, individuals who differ from the norm are expected to assimilate and adapt so as not to disrupt the structure. Those who are too different from the norm to fit in or who refuse to accept the binary structure are viewed as problems and are often ostracized or blamed for disturbing the system. Even when evidence to dispute the binary logic emerges, such evidence is often ignored or rejected in favor of maintaining the status quo. As such, the need for educators with a social justice orientation is needed. The purpose of this qualitative study was to understand the process one teacher used to create inclusive spaces for students who identify with differences in order to develop a more critical understanding of the work of social justice teachers. The findings suggest the teacher enacted behaviors and maintained beliefs that contradicted her espoused social justice orientation and her classroom was at once both inclusive and exclusive. The findings illustrate the complexities inherent within the work of equity-oriented educators. Implications for educator preparation is discussed.  相似文献   

Time Comparison between the Cross-Over and Jab-Step Starts     

Richard G. Israel 《Research quarterly for exercise and sport》2013,84(3):521-523

Abstract

The purpose of this investigation was to evaluate and quantify physiological differences among groups of distance runners. The subjects included 20 elite distance runners (8 marathon, 12 middle-long distance) and 8 good runners. Working capacity and cardiorespiratory function were determined by submaximal and maximal treadmill tests, and body composition by hydrostatic weighing. The variables studied were maximum oxygen uptake ([Vdot]O₂ max), [Vdot]O₂ submax, lactic acid submax, lean body weight, and fat weight. MANOVA showed that the good runners differed from the elite runners (p < 0.01) and the elite marathon runners differed from the elite middle-long distance runners (p < 0.05). Discriminant analysis showed that both functions were significant. The first was a general physiological efficiency factor that separated the good and elite runners. The second separated the elite marathon and middle-long distance groups. The second function showed that the marathon runners had lower lactic acid submax values. The middle-long distance runners had higher [Vdot]O₂ max values. Classification analysis was used to evaluate the accuracy of the discriminant analysis; 80% of the elite runners were correctly classified as marathon or middle-long distance runners. The discriminant functions were used to develop a multivariate scaling model for evaluating distance runners. Two premier runners, one marathoner (F. Shorter) and one middle-long distance runner (S. Prefontaine), were found to be at the extremes of the scale. The data showed that the discriminant functions provided a valid model for evaluating differences among elite distance runners.  相似文献   

Experimental evidence for improved neuroimaging interpretation using three-dimensional graphic models   总被引：1，自引：0，他引：1

Three-dimensional (3D) or volumetric visualization is a useful resource for learning about the anatomy of the human brain. However, the effectiveness of 3D spatial visualization has not yet been assessed systematically. This report analyzes whether 3D volumetric visualization helps learners to identify and locate subcortical structures more precisely than classical cross-sectional images based on a two dimensional (2D) approach. Eighty participants were assigned to each experimental condition: 2D cross-sectional visualization vs. 3D volumetric visualization. Both groups were matched for age, gender, visual-spatial ability, and previous knowledge of neuroanatomy. Accuracy in identifying brain structures, execution time, and level of confidence in the response were taken as outcome measures. Moreover, interactive effects between the experimental conditions (2D vs. 3D) and factors such as level of competence (novice vs. expert), image modality (morphological and functional), and difficulty of the structures were analyzed. The percentage of correct answers (hit rate) and level of confidence in responses were significantly higher in the 3D visualization condition than in the 2D. In addition, the response time was significantly lower for the 3D visualization condition in comparison with the 2D. The interaction between the experimental condition (2D vs. 3D) and difficulty was significant, and the 3D condition facilitated the location of difficult images more than the 2D condition. 3D volumetric visualization helps to identify brain structures such as the hippocampus and amygdala, more accurately and rapidly than conventional 2D visualization. This paper discusses the implications of these results with regards to the learning process involved in neuroimaging interpretation.  相似文献   

Extrinsic and intrinsic risk factors associated with injuries in young dancers aged 8-16 years     

Steinberg N  Siev-Ner I  Peleg S  Dar G  Masharawi Y  Zeev A  Hershkovitz I 《Journal of sports sciences》2012,30(5):485-495

In the present study, we tried to determine the association between joint ranges of motion, anatomical anomalies, body structure, dance discipline, and injuries in young female recreational dancers. A group of 1336 non-professional female dancers (age 8-16 years), were screened. The risk factors considered for injuries were: range of motion, body structure, anatomical anomalies, dance technique, and dance discipline. Sixty-one different types of injuries and symptoms were identified and later classified into four major categories: knee injuries, foot or ankle tendinopathy, back injuries, and non-categorized injuries. We found that 569 (42.6%) out of the 1336 screened dancers, were injured.The following factors were found to be associated with injuries (P < 0.05): (a) range of motion (e.g. dancers with hyper hip abduction are more prone to foot or ankle tendinopathies than dancers with hypo range of motion; (b) anatomical anomalies (scoliotic dancers manifested a higher rate of injuries than non-scoliotic dancers); (c) dance technique (dancers with incorrect technique of rolling-in were found to have more injuries than dancers with correct technique); (d) dance discipline (an association between time of practice en pointe and injury was observed); and (e) early age of onset of menarche decreased risk for an injury. No association between body structure and injury was found. Injuries among recreational dancers should not be overlooked, and therefore precautionary steps should be taken to reduce the risk of injury, such as screening for joint range of motion and anatomical anomalies. Certain dance positions (e.g. en pointe) should be practised only when the dancer has already acquired certain physical skills, and these practices should be time controlled.  相似文献

Storage and retrieval considerations of binary data bases     

Israel Spiegler  Rafi Maayan 《Information processing & management》1985,21(3):233-254

A binary approach to data storage and retrieval is introduced. It views the data base as a two-dimensional matrix that relates entities to all possible values the attributes of these entities may take. As such, it provides a unified solution to the two conflicting types of data base transactions—operational and managerial. An analytical investigation of the feasibility of binary storage and a compression method for reducing meaningless areas of the matrix are presented. Storage efficiencies of binary and conventional inverted file methods are compared and evaluated. An analysis of retrieval considerations associated with the binary matrix is given, particularly the issue of going from high to low orders of compression. Results of these analyses indicate that the binary data base's efficiency increases with increases in query complexity. Future research directions are sited and discussed.  相似文献
