Although reminiscence is a behavior common to all ages, research to date has been conducted only with older adults. This study sought to explore the phenomenon with adults of various ages with the anticipation that comparative information would lead to a better conceptualization of the behavior and its functions. It was hypothesized that there would be no difference in what adults reminisced about, why they reminisced, or how they reminisced with respect to age, sex, education, or socioeconomic status. A sample of 309 adults ranging in age from 18 to 90 were asked to complete a survey exploring various aspects of reminiscence. Analysis of variance and chi‐square were used to assess differences in reminiscent behavior across age, sex, education, and social class. There were no systematic differences with regard to education or social class. On several dimensions sex emerged as a more important variable than age, suggesting that age may not be as important a consideration in simple reminiscence as has been previously assumed. 相似文献

This study aimed to analyse fatigue-induced changes in mechanical sprinting properties during a specific repeated-sprint test in elite rugby sevens athletes. Twenty elite rugby sevens players performed ten 40?m sprints on a 30?s cycle with participant’s running back and forth in a marked lane. Radar was used to assess maximal overground sprint performance over each 40?m. Macroscopic mechanical properties (maximal horizontal force (F0), maximal horizontal power (Pmax), maximal ratio of horizontal force (RFpeak), decrease in the ratio of horizontal-to-total force (DRF), total force and maximal sprinting velocity (v0)) were drawn from horizontal force velocity relationships, using a validated method applied to the speed–time data. Fatigue-induced changes were analysed comparing the first sprint to an average of 2nd-4th, 5th-7th and 8th-10th. Repeated-sprint ability (RSA) testing induced substantial changes in the maximal velocity component, with a decrease (–15%) in v0 (effect size (ES)?=?–2.46 to –4.98), and to a lower extent (–5.9%) in the maximal force component F0 (ES?=?–0.59). DRF moderately decreased (14%; ES=–0.76–1.11), and RFpeak largely decreased in the later sprints (ES?=?–0.32 to –1.27). Fatigue observed in this RSA test appeared to have a greater effect on the technical ability to produce horizontal force at high velocities, likely due to an alteration in the ability to maintain horizontally oriented force application when velocity increases rather than during the initial acceleration phase, but also the overall force production capacity. The ability to maintain forward-oriented force at high velocities is of central importance for identifying fatigue and monitoring load. 相似文献

The law is a near perfect application area for knowledge representation. Legal knowledge representation is needed in conceptual legal information retrieval systems and in legal reasoning systems. We review the knowledge representation aspects of four such systems: Waterman and Peterson's Legal Decisionmaking System, Hafner's Legal Information Retrieval System, McCarty's TAXMAN, and the deBessonet representation of the Louisiana Civil Code (CCLIPS). 相似文献

Conclusion Science teaching in Australia has been dogged by a lack of independence from the top-down pressures of the tertiary institutions
and overseas, particularly British, influences. In a future paper we will examine the influence of Professor Harry Messel
of Synney University and his Philosophy of Science as exemplified by the Wyndham Science Course for secondary schools in NSW.
Science teaching continues to ignore such questions as, whose interests are served by the managers of scientific research?
There is an absence of discussion about autonomous technology and growth economics advocated by Australian and other governments.
Even the curious juxtaposition of caution and demand for more technology by Barry Jones inSleepers, Wake! (1982) has failed to stimulate discussion. 相似文献

Problem‐solving teams (PST) play an important role with regard to organizational performance in restructured schools. The concepts of team‐work and team effectiveness are examined and related to functions of problem‐solving teams. A case study of a successful PST provides a framework for the development of propositions on effective PSTs which may be subject to testing. 相似文献
