The present study reported on translating the Exercise Identity Scale (EIS: Anderson & Cychosz, 1994) into Greek and examining its psychometric properties and cross-cultural validity based on U.S. individuals' EIS responses. Using four samples comprising 33, 103, and 647 Greek individuals, including exercisers and nonexercisers, and a similar sample comprising 800 U.S. individuals, the concurrent validity, factor structure, internal reliability, test-retest reliability, external validity, gender invariance, and cross-cultural validity of the EIS responses were examined using confirmatory factor analytical procedures. The results supported the concurrent validity, an adequate unidimensional factor structure for the translated EIS and the internal reliability and test-retest reliability over a 6-week interval. Further, cross-gender configural, partial metric, partial strong factorial, and partial strict factorial invariance and cross-cultural configural and partial metric invariance supported the cross-cultural equivalence of the EIS versions. Moreover, the external validity of the translated EIS responses was also supported. Overall, the findings supported the validity of the exercise identity construct outside North American boundaries and the EIS items' equivalence, providing initial evidence for its cross-cultural applicability. 相似文献

Regulation of clinical practice is a characteristic aspect of the medical profession. Regardless of whether this regulation derives from government-sourced guidelines or materials from government-sponsored institutions, it results in a high production of information resources (institutional information resources), which are disseminated to the clinical stuff in order to ensure compliance. In that case, the issue of credibility of these information resources might arise, since medical practice is characterized by a high frequency of change. The latter involves a continuous effort on the part of the clinical staff, which is motivated by work-related factors (e.g., need for compliance) or personal motivation (e.g., need for self-improvement). In this study we consider a simple trust model, according to which we assume that perceived trust is a direct antecedent of perceived credibility. We evaluate whether work-related or personal motivating factors influence the relation between perceived credibility and trust toward institutional information sources and how the effect of each factor affects this relation. Findings suggest that work-related factors have a higher impact on the relation between credibility and trust than personal motivation factors, while they are stressing the important role of hospital libraries as a dissemination point for government-sponsored information resources. 相似文献

This study examined the extent of measurement invariance of the Basic Psychological Needs in Exercise Scale responses (BPNES; Vlachopoulos & Michailidou, 2006) across male (n = 716) and female (n = 1,147) exercise participants. BPNES responses from exercise participants attending private fitness centers (n = 1,012) and community exercise programs (n = 851) were used. The 3-factor BPNES confirmatory factor analysis model, discriminant validity, and scale reliability were supported for both male and female participants separately. The multisample models supported the configural invariance, partial metric invariance, partial measurement error invariance, and partial scalar invariance of the BPNES responses across gender. Both male and female participants attached the same meaning to the constructs assessed by the BPNES items. The BPNES score invariance properties support tests of the needs universality hypothesis offered by self-determination theory across gender in exercise and meaningful comparison of the autonomy, competence, and relatedness construct latent means across gender. 相似文献

Adequate response to mail health surveys by minority populations has proved problematic. The impact of mail survey design features utilized to promote Orthodox Jews' responses (N = 138; 82 eligible synagogue member households) to a mailed questionnaire used to measure walking behavior are described and assessed. An examination of response characteristics by wave as an estimate of nonresponse bias and calculations of response speed and cost-effectiveness were conducted. Response rates of 54.8% and 52.9% for eligible households and individuals, respectively, were accumulated by using 9 of 14 recommended mail survey techniques for this particular population (e.g., culturally appropriate salutation and closing, religious iconography, Talmudic aphorisms, and incentives linked to Hebraic numerology and the synagogue's building fund). Nonrespondents most frequently cited business, forgetfulness, or lack of topic salience as reasons for not responding. No differences on sociodemographic items and 9 of 11 continuous variables were observed by response wave; response speed was slowest in response to later mailing waves; and cost-effectiveness was maximal during postcard follow-up (E statistic = 3.74). Nonresponse bias may not be problematic with a > 50% response rate in this particular population. Front-loading incentives may prompt quicker response and improve cost-effectiveness. Specific design considerations for future consideration and testing are provided. 相似文献

Sourcing technological knowledge through corporate acquisition: Evidence from an international sample of high technology firms 总被引：2，自引：0，他引：2
We investigate the prevalence of the motive to source technological knowledge externally through corporate acquisition. Drawing on make-or-buy and organizational learning theories, we infer the implications of this explanation for the acquirers' pre-acquisition innovative characteristics. Using an international sample of 6106 high technology acquisitions during 1984–2000, we assess the contribution of innovative characteristics to the acquisition likelihood. For firms acquiring small private firms and former subsidiaries—but not public targets—the evidence is consistent with three propositions: (1) A firm's commitment to internal R&D is negatively affected by the decision to acquire; (2) Low R&D productivity increases the likelihood of acquisition; (3) A large knowledge stock predisposes firms to acquire because they perceive they are capable of selecting and absorbing targets. We conclude that acquisitions of small private firms and former subsidiaries are a viable R&D strategy to explore a range of potential future innovation trajectories for large public firms. 相似文献

ABSTRACT Parents and teachers of 109 children selected from the Special Needs Register and living in a multiethnic urban health district participated in the study. Their perceptions of children's behaviour at home and at school were measured by the Aberrant Behavior Checklist(ABC). About two‐thirds of the subjects presented with at least one type of maladaptive behaviour of at least moderate severity within their family, and 50 per cent had similar difficulties at school. The dimensions of hyperactivity and irritability were the main causes for concern by both sources. Contrary to previous studies, high rates of parent‐teacher agreement were found. This significant association was not affected by factors such as age, ethnicity or type of school. The implications for the provision of services for children in special education are discussed. 相似文献

In this paper we investigate the role of workers’ training history in determining current training-incidence. The analysis is conducted on an unbalanced sample comprising information on approximately 5000 employees from the first seven waves of the BHPS. Training participation is modelled as a dynamic random effects probit model where the effects of unobserved heterogeneity and initial conditions are accounted for in a fashion consistent with methods proposed by Chamberlain (1984) and Wooldridge (2005), respectively. The results suggest that prior training experience is a significant determinant of a worker's participation in a current training episode comparable with other formal educational qualifications. 相似文献

In our research, we investigated whether students will develop inquiry skills, such as hypothesis exploration and formulation
and interpretation, and metacognitive skills, such as comprehension of new knowledge, as a result of a storytelling strategy
employed during teaching. We also investigated whether students will utilize the skills and knowledge acquired in the learning
process to explain everyday-life phenomena or applications of science. In order to achieve the above objectives, we carried
out a bibliographical research, in which we established the certainty that modern thought is integrated in dialogical and
narrative forms and that the conceptual approach, which places emphasis on the purely cognitive dimension of the process of
knowledge and ignores inspiration or imagination, is ineffective. These conclusions necessitated our turning to other approaches
for teaching and learning. We chose storytelling on account of its ability to cultivate the imagination and inspiration and
to make science learning attractive to students. To confirm our findings, we conducted research on the effectiveness of storytelling
in teaching science in five sixth-grade, primary-school classes. The findings of this research are described in our paper
and seem to be encouraging. 相似文献

The present study examined the link between motivation profiles among adult sports participants and the consequences of enjoyment, effort, positive and negative affect, attitude toward sport participation, intention to continue sport participation, satisfaction, and frequency of attendance in sport. Two samples of participants (n = 590 and n = 555) completed the Sport Motivation Scale and a range of self-report measures to assess the outcome variables. Exploratory cluster analyses applied to Sample 1 and confirmatory cluster analysis applied to Sample 2 identified two clusters of sport participants. The first comprised participants with high scores on both nonself-determined and self-determined motives. The second comprised participants with high scores on self-determined motives but low scores on nonself-determined motives. Participants in the first cluster scored higher on all outcome variables. The results are discussed with reference to a more in-depth understanding of the motivation dynamics of sport participation based on Self-Determination Theory. 相似文献
