Cerebral activity, as reflected by power in the alpha waveband (8-13 Hz), was examined prior to the performance of three tasks with different effort and accuracy requirements. The study aimed to further investigate changes in activity observed in an earlier study in which expert karate performers exhibited significant increases in alpha band power during preparation for a training task. In contrast to the earlier research, the high effort task produced a significant decrease in 'alpha' power prior to performance. 'Alpha' power prior to the high accuracy task showed significant differences mediated by the outcome. Successful performance was preceded by higher levels of 'alpha' power than unsuccessful attempts. The reported use of a cognitive strategy on the first task produced a significant difference in activity, lower alpha power being associated with the use of such a technique. 相似文献

This study investigates professional autonomy as experienced by psychotherapists in Korea and in the United States using data collected as part of a collaborative international study of the development of psychotherapists (Orlinsky et al. (1999). Psychotherapy Research, 9(2), 127–153; Orlinsky & Rønnestad, (2005). How psychotherapists develop: A study of therapeutic work and professional growth. Washington, DC: American Psychological Association). The major aims are: to compare the extent of professional autonomy experienced by psychotherapists in Korea and by their counterparts in the USA; and to explore the professional and social correlates of the professional autonomy experienced by Korean therapists and compare these with the correlates of autonomy experienced by American therapists. These aims are pursued through analyses of a database of questionnaire responses. Results indicate that Korean therapists, compared to American therapists in our sample experience significantly lower levels of professional autonomy. For Korean therapists, whether they have a salient theoretical orientation in their practice is the single most important influence in their experience of work autonomy. Seniority and work setting are also significant correlates of autonomy for the Korean therapists. Similar to Korean therapists, seniority and having a salient orientation are also important influences on the way American therapists experience professional autonomy. American therapists, who work in independent practice experience higher work autonomy, whereas American social workers tend to experience lower professional autonomy. 相似文献

In this paper I argue the rationale for the assessment criteria currently in use on the Aston University MSc in TESOL/TESP. These assessment criteria were revised in 1998–1999; here I discuss the goals of the revision project and argue that they have been successfully met by the assessment scheme which was developed. The discussion is offered for two main purposes. Firstly, the framework itself may be of interest to other departments who assess similar research reports to the course assignments discussed here. Secondly, and more importantly, the paper offers a position on the kinds of questions that should be asked and the sorts of places to look for answers for any project to (re)define assessment criteria in an academic programme. 相似文献

Characteristics of early adopters of end-user online searching in the health professions 总被引:1,自引:0,他引:1
J G Marshall 《Bulletin of the Medical Library Association》1989,77(1):48-55
This paper examines end-user, online searching using data from a questionnaire mailed to 150 Canadian health professionals in practice settings. The response rate was 83% (n = 124). The data provide a demographic profile of early adopters of end-user searching in the health care community. Positive correlations with the user's level of implementation of end-user searching were found for the following variables: amount of time spent in research activities, amount of system training received, and use of Medical Subject Headings (MeSH). There was a negative association between the amount of time spent in patient care and implementation level. General practitioners and family physicians had lower implementation levels than physicians in other specialties. Successful implementers were more likely to be computer literate and to place a high value on formal information sources such as books, journals, and libraries. Health professionals using so-called "user-friendly" or menu-based software had lower levels of personal commitment to using online databases, as measured by a combination of continuance of use, willingness to pay personally, type of recommendations made to colleagues, and hardware ownership. 相似文献

This study was designed to examine children's attitudes toward the role of sports in determining social status, as well as the activities in which children prefer to participate. A total of 227 boys and 251 girls in Grades 4, 5, and 6 completed a questionnaire to determine which criteria were most important in determining personal, female, and male popularity. Personal popularity was answered by the girls and boys according to "what would make you well liked by your classmates." Female and male popularity was determined by asking both girls and boys to decide "what would make (girls, for female subjects, and boys, for male subjects) well liked by your classmates." A comparison of results from the Buchanan, Blankenbaker, and Cotten (1976) investigation and the present study indicated that, in the last 15 years, appearance has become more important and academic achievement less important in determining personal popularity for girls. For boys, the comparison revealed that sports have become more important and academic achievement less important in determining personal popularity. Boys reported sports to be the most important determinant of personal and male popularity and appearance as the most important determinant of female popularity. Sports and appearance became more important for boys with each higher grade level. Girls reported appearance to be the most important determinant of personal, male, and female popularity. For girls, appearance became more important with each higher grade level. A comparison of results from the Buchanan et al. (1976) and the present study indicated that the activities in which girls and boys preferred to participate have changed.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

The Alfred Taubman Medical Library at the University of Michigan has offered instruction in online literature searching to third-year pharmacy students as a component of the course "Drug Information and Scientific Literature Evaluation" since 1983. In the spring of 1989, a follow-up study was conducted to assess the impact of instruction on four classes of graduates. Of a pool of 151 graduates, 90 (60%) responded to a mailed questionnaire on their use of information and computerized literature searching. The respondents were divided into four subgroups: end-user searchers, users of intermediaries, end users who used intermediaries, and those who did not use computerized literature search systems. Seventy-two percent of the respondents used some type of computerized literature searching, and 42% performed their own searches. The four subgroups differed in general computer use, familiarity with MEDLINE search terminology, information use, reasons for using or not using literature searching, and characteristics of searches (i.e., type, time frame, amount, and frequency). Training in end-user search systems appears to have had an impact on the continued use of computerized literature searching several years after the formal educational program. 相似文献
