The kinds of messages teachers give students regarding the value of credentials in the job-getting package during a period of high youth unemployment are explored. The response made by students to the credentialling ideology promoted in schools, and their construction of the job-getting formula, are also described. The validity of the two versions of job-getting strategies is considered in the light of evidence provided by a number of empirical research projects. The superiority of student knowledge in this area is used to present a case for a critical and democratic education which appropriates and legitimises the student voice. 相似文献

A multidisciplinary group of genetic and other professionals discuss a complex case of familial conflict over access to genetic information. One twin wishes to know the results of her deceased mother's tests for BRCA1 mutations; a second twin objects to researchers making this information available. As the case discussion unfolds, the apparent facts of this case are called into question and the lines of ethical certainty become less clear. 相似文献

This paper describes the basic elements of practice development and management within the academic medical setting. These include assessment of the market environment, both in the community and within the medical setting, product development, marketing, budget basics, quality, managed care negotiations, and finding time to do research in a financially-driven health care system. 相似文献

This study examined a research model developed to understand psychological burnout among police officers. Data were collected
from 828 men and women in police work using questionnaires completed anonymously. Five groups of predictor variables identified
in previous research were considered: individual demographic and situational variables, work stressors, stressful events,
work-family conflict and coping responses. Sources of stress (chronic stressors, stressful events, work-family conflict) were
significantly related to levels of psychological burnout when individual demographic and situational variables were controlled. 相似文献

This paper addresses some critical issues in the applicability of quantitative performance measures (including bibliometric,
economic, and co-occurrence measures) to the assessment of basic research. The strengths and weaknesses of metrics applied
as research performance measures are examined. It is concluded that metrics have a useful role to play in the evaluation of
research. Each metric employed, whether bibliometric, economic, co-occurrence, or others, brings a new dimension of potential
insight to the complex problem of research assessment. However, when used in a stand-alone mode, metrics can be easily misinterpreted
and result in misleading conclusions. Metrics should be an integral part of a more comprehensive approach to research evaluation,
in which the leading role is assumed by expert peer review. Under this structure, the reviewers must be broadly constituted,
so that the technical correctness of the research approaches being taken (doing the job right) can be evaluated by technical
experts and the correctness of the research target (doing the right job) can be evaluated as well. This comprehensive approach
insures quality in the implementation of existing research paradigms and allows the introduction of revolutionary new research
paradigms as well.

There are many conditions in which identification proceeds faster for the global form of a hierarchical pattern than for its local parts. Since the global form usually contains more lower spatial frequencies than do the local forms, it has frequently been suggested that the higher transmission rate of low spatial frequencies is responsible for the global advantage. There are also functional hemispheric differences. While the right hemisphere is better at processing global information, the left hemisphere has an advantage with respect to local information. In accordance with the spatial-frequency hypothesis, it has been speculated that this difference is due to a differential capacity of the hemispheres for processing low and high spatial frequencies. To test whether low spatial frequencies were responsible for the global advantage and/or for the observed hemispheric differences, two experiments were carried out with unfiltered and highpass-filtered compound-letter stimuli presented at the left, right, or center visual field. The first experiment, in which the target level was randomized in each trial block, revealed that low spatial frequencies were not necessary for either global advantage or for hemispheric differences. Highpass filtering merely increased the response times. In the second experiment, the target level was held constant in each block. This generally increased the speed of responding and produced interactions between filtering and global-local processing. It was concluded that both sensory and attentional or control mechanisms were responsible for global precedence and that the hemispheres differed with respect to the latter. 相似文献

Brain-damaged patients with unilateral spatial neglect ignore aspects of the world located on the side opposite their lesion. In the present study we examined the performance of unilateral neglect patients (UN) on an SRT task in which a hybrid repeating sequence (21313) was used. We analyzed the patients' performance for each location separately as a function of the target's location in the trial preceding the response. The UN patients were severely limited in their learning of the sequence when compared to normal controls. In particular, they appeared to learn unique associations (21 and 13) but not ambiguous ones (31 and 32). We discuss two possible explanations for this phenomenon. The first is that UN patients show a deficit similar to that of normal subjects in dual task situations. The second is that the learning deficit is unique to spatial processing impairments of UN patients and is not directly related to research with normal population. We outline future research that may distinguish between these two explanations. 相似文献

This study evaluated the hypothesis that shyness is uniquely associated with delayed development of personal resources for dealing with career tasks during the college years. In addition to shyness, the set of relevant personality factors included academic self-esteem and dysphoria. Canonical correlation and semipartial analysis were used to assess the mutual and unique variance associated with these three personality factors and a set of career development variables pertinent to college students in late adolescence. Results revealed that shyness was uniquely related with vocational self-concept crystallization and aspects of vocational maturity (e.g., attitudes toward planning), but unrelated with indexes of self and environmental exploration. Academic self-esteem was only related to vocational self-concept, while dysphoria evidenced no unique association with any career variables. Implications of the expected and unexpected findings are discussed. 相似文献

The origins of fear and phobia of blood, injury, and injections were investigated in a sample of 128 fearful university students. Based on Mutilation Questionnaire scores, subjects were designated as common fear, high fear, or phobic. Ss reports of their onset experiences obtained from structured interviews were categorized into one or more acquisition pathways of conditioning, vicarious observation, and information. Of the 73% of Ss who recalled one or more onset experiences, 76% reported conditioning-like events as the primary pathway with the majority reporting fear-related UCSs. Vicarious experiences were reported as primary by 20% and 3% reported information as being primary in their fear onset. Severity of fear was unrelated to the pathway by which it was acquired, to whether the onset was recalled, and if recalled, whether it was due to a single or to multiple traumatic events. Results are discussed in terms of methodological problems of memory issues and means by which data are collected. 相似文献
