Beliefs about parents' legitimate authority and adolescents' obligations to disclose to parents and actual disclosure and secrecy in different domains were examined in 276 ethnically diverse, lower middle-class 9th and 12th graders (Ms=14.62 and 17.40 years) and their parents (n=249). Adolescents were seen as more obligated to disclose prudential issues and less obligated to disclose personal than moral, conventional, and multifaceted issues; parents viewed adolescents as more obligated to disclose to parents than adolescents perceived themselves to be. Adolescents disclosed more to mothers than to fathers, particularly regarding personal issues, but mothers overestimated girls' disclosure. Greater trust, perceived obligations to disclose, and, for personal issues, more parental acceptance and psychological control predicted more disclosure and less secrecy.  相似文献   

Stimulus space complexity determines the ratio of specialist and generalist neurons during pattern recognition     

Aaron Montero  Ramon Huerta  Francisco B. Rodriguez 《Journal of The Franklin Institute》2018,355(5):2951-2977

Neural processing layers built on divergent connectivity patterns display two types of stimulus-dependent responses: neurons that react to a few stimuli, specialists, and other ones that respond to a wide range of inputs, generalists. Specialists are essential for the discrimination of stimuli and generalists extract common and generic properties from them. This neural heterogeneity could have emerged because of animal adaptation to the environment. Thus, we suggest that there is a relationship between the percentage of specialists and generalists and the stimulus complexity. In order to study this possible relationship, we use patterns with different complexities in a bio-inspired neural network and calculate their classification errors for different ratios of these types of neurons. This study shows that, when the complexity of the stimuli is low, the minimum classification error is achieved with almost any specialist-generalist ratio. Thus, in this case, the role of these neurons during pattern recognition is unspecific. When this complexity is intermediate, both are needed to minimize the classification error, usually in a similar proportion. For increasing stimulus complexity, the importance of generalists decreases, until their relevance is fully nullified when the complexity is high. Therefore, if we adjust the specialist-generalist ratio to the complexity of patterns, we can build more effective neural networks for pattern recognition. Finally, we propose an estimation of stimulus complexity based on the proportion of these types of neurons observed by neural recordings. This offers the possibility to evaluate the stimulus complexity to which animals are adapted.  相似文献   

The physical profile of adult male basketball players: Differences between competitive levels and playing positions

This study examined the physical differences in adult male basketball players of different competitive level and playing position using a large cohort. In the middle of the regular season, 129 players from four different Divisions completed a Yo-YoIR1 and, after 3-to-8 days, they performed a 6-min continuous running test (Mognoni’s test), a counter-movement jump (CMJ) test and a 5-min High-intensity Intermittent running test (HIT). Magnitude-based inferences revealed that differences in HIT were very likely moderate between Division I and II and likely small between Division II and III. The differences in absolute peak power and force produced during CMJs between Division I and II and between Division II and III were possibly small. Differences in Yo-YoIR1 and Mognoni’s test were very likely-to-almost certain moderate/large between Division III and VI. We observed possibly-to-likely small differences in HIT and Mognoni’s test between guards and forwards and almost certainly moderate differences in absolute peak power and force during CMJs between guards and centres. The ability to sustain high-intensity intermittent efforts (i.e. HIT) and strength/power characteristics can differentiate between competitive level, while strength/power characteristics discriminate guards from forwards/centres. These findings inform practitioners on the development of identification programs and training activities in basketball.  相似文献   

An Integrative Approach to Portfolio Evaluation for Teacher Licensure   总被引：3，自引：0，他引：3  

Pamela A. Moss  Aaron M. Schutz  Kathleen M. Collins 《Journal of Personnel Evaluation in Education》1998,12(2):139-161

The purpose of our overall research agenda is to develop and evaluate a methodology for the assessment of teachers in which experienced teachers, serving as judges, engage in dialogue to integrate multiple sources of evidence about a candidate to reach a sound conclusion. The project that provides the venue for this research agenda is the Interstate New Teacher Assessment and Support Consortium (INTASC), which is developing a portfolio assessment system to assist participating states in making a decision about teacher licensure. To develop the theoretical foundation necessary to support and evaluate such dialogic and integrative assessment practices, we turn, in part, to the tradition of philosophical hermeneutics, as a complement to psychometrics. In this article, we characterize and assess the processes in which judges, trying out an integrative approach to portfolio evaluation for the first time, engage as they collaboratively construct and document their conclusions, and we locate this work in the larger research agenda. The premise of this project, which is being carefully evaluated in the course of inquiry, is that these integrative practices cannot only lead to an epistemologically sound evaluation of teaching but also promote an ongoing professional dialogue of critical reflection on teaching practice.  相似文献   

Contextual influences and athlete attitudes to drugs in sport

This article reports on 11 narrative-based case histories which sought to: (1) uncover the attitudes of players and athletes to drugs in sport, and (2) explore contextual factors influencing the formation of those attitudes as informed by social ecology theory. Overall, participants viewed the use of banned performance-enhancing substances as cheating, ‘hard’ non-performance-enhancing recreational or illicit substances as unwise, legal non-performance-enhancing substances as acceptable, and legal performance-enhancing substances as essential. In short, attitudes were sometimes quite libertarian, and contingent upon first, the legality of the substance, and second, its performance impact. Results also indicated that athletes’ attitudes about drugs were fundamentally shaped by sport's culture. Other significant factors included its commercial scale, closely identifiable others, early experiences and critical incidents of players and athletes, and their level of performance.  相似文献
