The genetic and environmental covariation among psychopathic personality traits, and reactive and proactive aggression in childhood     

Bezdjian S  Tuvblad C  Raine A  Baker LA 《Child development》2011,82(4):1267-1281

The present study investigated the genetic and environmental covariance between psychopathic personality traits with reactive and proactive aggression in 9- to 10-year-old twins (N = 1,219). Psychopathic personality traits were assessed with the Child Psychopathy Scale (D. R. Lynam, 1997), while aggressive behaviors were assessed using the Reactive Proactive Questionnaire (A. Raine et al., 2006). Significant common genetic influences were found to be shared by psychopathic personality traits and aggressive behaviors using both caregiver (mainly mother) and child self-reports. Significant genetic and nonshared environmental influences specific to psychopathic personality traits and reactive and proactive aggression were also found, suggesting etiological independence among these phenotypes. Additionally, the genetic relation between psychopathic personality traits and aggression was significantly stronger for proactive than reactive aggression when using child self-reports.  相似文献   

Does generating examples aid proof production?     

Paola Iannone  Matthew Inglis  Juan Pablo Mejía-Ramos  Adrian Simpson  Keith Weber 《Educational Studies in Mathematics》2011,77(1):1-14

Many mathematics education researchers have suggested that asking learners to generate examples of mathematical concepts is an effective way of learning about novel concepts. To date, however, this suggestion has limited empirical support. We asked undergraduate students to study a novel concept by either tackling example generation tasks or reading worked solutions to these tasks. Contrary to suggestions in the literature, we found no advantage for the example generation group on subsequent proof production tasks. From a second study, we found that undergraduate students overwhelmingly adopt a trial and error approach to example generation and suggest that different example generation strategies may result in different learning gains. We conclude by arguing that the teaching strategy of example generation is not yet understood well enough to be a viable pedagogical recommendation.  相似文献   

Discourse communities: A framework from which to consider professional development for rural teachers of science and mathematics     

Russell Tytler  David Symington  Linda Darby  Cliff Malcolm  Valda Kirkwood   《Teaching and Teacher Education》2011,27(5):871-879

This paper explores aspects of professional development for teachers of science and mathematics in schools in rural Australia. The study identified a range of issues including tensions between government, school and individual professional learning priorities and their respective responsibilities; the shaping of professional development by rurality; and issues of generic versus subject-specific professional learning. The paper will focus on the needs of teachers, particularly secondary teachers, for subject-specific professional development and the capacity of different professional development approaches for satisfying these needs. The notion of discourse communities is proposed as a framework for considering this issue.  相似文献   

Science and the major racket sports: a review   总被引：1，自引：1，他引：0  

Lees A 《Journal of sports sciences》2003,21(9):707-732

The major racket sports include badminton, squash, table tennis and tennis. The growth of sports science and the commercialization of racket sports in recent years have focused attention on improved performance and this has led to a more detailed study and understanding of all aspects of racket sports. The aim here, therefore, is to review recent developments of the application of science to racket sports. The scientific disciplines of sports physiology and nutrition, notational analysis, sports biomechanics, sports medicine, sports engineering, sports psychology and motor skills are briefly considered in turn. It is evident from these reviews that a great deal of scientific endeavour has been applied to racket sports, but this is variable across both the racket sports and the scientific disciplines. A scientific approach has helped to: implement training programmes to improve players' fitness; guide players in nutritional and psychological preparation for play; inform players of the strategy and tactics used by themselves and their opponents; provide insight into the technical performance of skills; understand the effect of equipment on play; and accelerate the recovery from racket-arm injuries. Racket sports have also posed a unique challenge to scientists and have provided vehicles for developing scientific methodology. Racket sports provide a good model for investigating the interplay between aerobic and anaerobic metabolism and the effect of nutrition, heat and fatigue on performance. They have driven the development of mathematical solutions for multi-segment interactions within the racket arm during the performance of shots, which have contributed to our understanding of the mechanisms of both performance and injury. They have provided a unique challenge to sports engineers in relation to equipment performance and interaction with the player. Racket sports have encouraged developments in notational analysis both in terms of analytical procedures and the conceptualization of strategy and tactics. Racket sports have provided a vehicle for investigating fast interceptive actions, hand-eye coordination and perception-action coupling in the field of motor control. In conclusion, science has contributed considerably to our knowledge and understanding of racket sports, and racket sports have contributed to science by providing unique challenges to researchers.  相似文献   

48 million configurations and counting: platform numbers and their capitalization     

Adrian Mackenzie 《Journal of Cultural Economy》2018,11(1):36-53

Platforms are important actors in contemporary cultural economic processes. They include social network sites, online content management systems, streaming media platforms, mobile communication infrastructures, supply chain logistics solutions, and cryptocurrencies. Analysis of platforms and their capitalization should take into account the ways they structure social practice as assets and the constitutive opacity of platforms as configured realities. It explores capitalization by focusing on the problems of counting people and things on platforms. Via a case study of the software repository platform [Github.com] (https://github.com), it analyzes how 'platform numbers’ participate in capitalization. It describes attempts to enumerate the elements of the platform by counting, mapping or listing them. The paper shows how attempts to enumerate people and things encounter forms of association, duplication, combination, imitation and configuration that are crucial to the ensemble but remain refractory to capitalization. It proposes configurative enumeration of the platform numbers as a way of conceptualizing these un-enacted excesses. In a configurative enumeration, the composition, the rhythms of imitation, variation and commutation, and constant relating, repairing and adjusting of configurations crucial to the ongoing formation of platforms come into view. Configurative enumerations engage the inventive realities of platformization, realities that precede and sometimes overflow their capitalization.  相似文献   

Who’s counting whom? Non-National museum attendances in the UK: part 1     

Adrian Babbidge 《Cultural Trends》2018,27(4):239-250

ABSTRACT

This paper is the first part of a study on visit numbers to UK regional and local museums. It reviews the limited past research on the topic, examines the motivations for counting such visits and the means required to do so, and explores the methods used from the early nineteenth century to now. A concluding section discusses the theme within the context of modern public policy on museums.

In relating historic context to current practice, it shows that, irrespective of the general use of visit numbers as a proxy for public interest and institutional importance, the practice of collecting museum visit numbers continues to be inconsistent and their publication erratic. It suggests that the lack of accepted good practice makes this an area for improvement.  相似文献   

A three-dimensional kinematic analysis of the long jump take-off     

Graham-Smith P  Lees A 《Journal of sports sciences》2005,23(9):891-903

The long jump has been widely studied in recent years. Two models exist in the literature which define the relationship between selected variables that affect performance. Both models suggest that the critical phase of the long jump event is the touch-down to take-off phase, as it is in this phase that the necessary vertical velocity is generated. Many three dimensional studies of the long jump exist, but the only studies to have reported detailed data on this phase were two-dimensional in nature. In these, the poor relationships obtained between key variables and performance led to the suggestion that there may be some relevant information in data in the third dimension. The aims of this study were to conduct a three-dimensional analysis of the touch-down to take-off phase in the long jump and to explore the interrelationships between key variables. Fourteen male long jumpers were filmed using three-dimensional methods during the finals of the 1994 (n = 8) and 1995 (n = 6) UK National Championships. Various key variables for the long jump were used in a series of correlational and multiple regression analyses. The relationships between key variables when correlated directly one-to-one were generally poor. However, when analysed using a multiple regression approach, a series of variables was identified which supported the general principles outlined in the two models. These variables could be interpreted in terms of speed, technique and strength. We concluded that in the long jump, variables that are important to performance are interdependent and can only be identified by using appropriate statistical techniques. This has implications for a better understanding of the long jump event and it is likely that this finding can be generalized to other technical sports skills.  相似文献

Student intrinsic motivation,science teaching practices and student learning     

Adrian Fordham 《Research in Science Education》1980,10(1):107-117

Conclusion This paper has been concerned with the application of basic understandings about intrinsic motivation and curiosity behaviour to the teaching of science, and in particular senior high school biology. The important role of student knowledge in the generation, maintenance and resolution of cognitive conflict is congruent with the renewed interest in studying students' everyday knowledge of curriculum content. However the study of classroom teaching processes in terms of their facilitation of intrinsic motivation is not common. Yet the data collected in this study demonstrates the importance of closely examining the implementation of courses such as the Web of Life, if the arousal of intrinsic motivation is an intended student outcome. Both interview and observational data indicated that the teaching styles adopted by teachers in this study were not likely to engender curiosity amongst students. Perhaps this should be expected. The use of a wide range of reference materials to investigate problems that arise in the classroom, the encouragement of students to do additional work on a topic if they are particularly interested, and a willingness on the part of the teacher to allow students sufficient time to formulate their own solutions to problems are classroom processes which necessitate a greater flexibility in curriculum presentation than can be often tolerated by teacher and school management. Such processes may be incompatible with organisational properties of the school and the pressures often placed upon students to perform to a high standard on rigidly defined examinations.  相似文献
