Relationships among values, achievement orientations, and attitudes in youth sport   总被引：1，自引：0，他引：1

This research examines the value-expressive function of attitudes and achievement goal theory in predicting moral attitudes. In Study 1, the Youth Sport Values Questionnaire (YSVQ; Lee, Whitehead, & Balchin, 2000) was modified to measure moral, competence, and status values. In Study 2, structural equation modeling on data from 549 competitors (317 males, 232 females) aged 12-15 years showed that moral and competence values predicted prosocial attitudes, whereas moral (negatively) and status values (positively) predicted antisocial attitudes. Competence and status values predicted task and ego orientation, respectively, and task and ego orientation partially mediated the effect of competence values on prosocial attitudes and of status values on antisocial attitudes, respectively. The role of sport values is discussed, and new research directions are proposed.  相似文献   

Rodents,evolution, and prehistory     

Jean Chaline 《Endeavour》1977,1(2):44-51

The rodents, especially voles, evolved very rapidly during the Quaternary era. Their remains, particularly the teeth, were fossilised by the thousand in prehistoric deposits. The sites can be dated from the degree of evolution attained by the teeth. Since rodents are closely adapted to their biotopes and live under well defined climatic conditions, they are extremely valuable for reconstructing the landscapes and climates of prehistory. In many cases, a single rodent tooth can be used to assess the age of a human skull or a prehistoric settlement, and throw light on the environment and climate of the time.  相似文献   

Bond graphs for thermal energy transport and entropy flow     

Jean U. Thoma 《Journal of The Franklin Institute》1971

The transport of thermal energy in thermodynamics is described as the product of entropy flow and of the absolute temperature, in analogy to the volume flow and pressure in oil hydraulics and to electric charge flow (= current) and voltage in electronics. Bond graphs are shown to be especially suitable to describe the splitting of applied thermal energy into internal energy and external mechanical work. Transformers and the 0- and 1-junctions of Paynter can illustrate various entropy flow processes, including Carnot engines and heat exchangers. Entropy flow in heat conduction is distinguished from entropy convection, or transport by moving mass, where the entropy/temperature characteristic or equation of state is important. Irreversibilities are represented by impedance transformers reducing temperature and increasing entropy flow but conserving power.  相似文献

The influence of competences and support on school performance feedback use     

Jan Vanhoof  Jean Pierre Verhaeghe  Martin Valcke  Peter Van Petegem 《Educational studies》2011,37(2):141-154

Information‐rich environments are created to promote data use in schools for the purpose of self‐evaluation and quality assurance. However, providing feedback does not guarantee that schools will actually put it to use. One of the main stumbling blocks relates to the interpretation and diagnosis of the information. This study examines the relationship between data literacy competences, support given in interpreting the information, actual use of the feedback and potential school improvement effect. A randomised field experiment with 188 school principals from primary education was set up and a post‐test was used to investigate the effects of a support initiative. The results revealed that a minority of schools invested significantly in the interpretation and diagnosis of the school performance feedback (SPF), despite the fact that most of the respondents showed an interest in the SPF report. In addition, data competence support and the subsequent use of feedback were found to be limited.  相似文献   

Do increased resources increase educational attainment during a period of rising expenditure? Evidence from English secondary schools using a dynamic panel analysis     

Geoff Pugh  Jean Mangan  John Gray 《British Educational Research Journal》2011,37(1):163-189

This article estimates the effects of school expenditure on school performance at Key Stage 4 in England, over the period 2003–07 during which real per pupil expenditure increased rapidly. It adds to previous investigations by using dynamic panel analysis to: exploit time series data on individual schools that only recently has become available; adjust for the potential endogeneity not only of expenditure but also of other determinants of performance; and differentiate the short‐run and the (higher) long‐run attainment effects of spending changes. Consistent with other recent work, the article reports a generally significant but small effect of expenditure on school performance, but it also finds that the effect varies between specialist and non‐specialist schools, with the effect on the latter being larger. Further, the article identifies significant dynamics in the school improvement process, quantifies the long‐run effect of expenditure changes, suggests that spending effects increase with socio‐economic disadvantage, and quantifies absence effects.  相似文献   

A relational vector space model using an advanced weighting scheme for image retrieval     

Jean Martinet  Yves Chiaramella  Philippe Mulhem 《Information processing & management》2011

In this paper, we lay out a relational approach for indexing and retrieving photographs from a collection. The increase of digital image acquisition devices, combined with the growth of the World Wide Web, requires the development of information retrieval (IR) models and systems that provide fast access to images searched by users in databases. The aim of our work is to develop an IR model suited to images, integrating rich semantics for representing this visual data and user queries, which can also be applied to large corpora.  相似文献

Analogical reasoning in adolescents with intellectual disability: effects of external memories and time processing     

Caroline Denaes  Jean‐Louis Berger 《Journal of Research in Special Educational Needs》2014,14(2):82-95

Analogical reasoning involves the comparison of pictures as well as the memorisation of relations. Young children (4–7 years old) and students with moderate intellectual disability have a short memory span, which hampers them in succeeding traditional analogical tests. In the present study, we investigated if, by providing external memory hints, the visual aid could enable these participants to succeed in analogies comprising more relations than their memory span was able to manage. Our analogical test, composed of 2 × 2 matrices, was administered in two versions: the standard version, similar to traditional tests, required the participant to memorise all the relations involved in order to discover the solution, whereas the construction version required him/her to construct the answer part by part by using external memories, which potentially increased success by offloading the memory. Our results show that students with moderate intellectual disability reached results similar to typically developing control children when provided with external memory hints (referred to as external memories). Moreover, in the most complex levels of the test, they did not spend more time than control children in solving the analogies.  相似文献   

Creating and Capitalizing on the Town/Gown Relationship: An Academic Library and a Public Library Form a Community Partnership     

Kathleen Halverson  Jean Plotas   《The Journal of Academic Librarianship》2006,32(6):624-629

This article highlights the birth and current benefits of a partnership between Keene State College and Keene Public Library. It is a smaller one-on-one partnership that represents a rarer model than that of consortia and joint-use library partnerships. The authors offer additional ideas for partnering with local community groups in order to strengthen the town/gown relationship.  相似文献
