The definition of epistemological beliefs takes on different shades of meaning from study to study; but, in general, researchers of personal epistemology are interested in what individuals believe about the source, certainty, and organization of knowledge, as well as the control and the speed of learning. Epistemological beliefs have been found to relate to reading comprehension, learning in complex and ill-structured domains, as well as learners' active participation and persistence in learning. Researchers are at odds on the issues of epistemological development and the roles that education and culture play in epistemological beliefs.  相似文献

This study examined the relationship between organizational support, work-family conflict, and job and life satisfaction among coaches. Data from collegiate head coaches with families (N = 253) were gathered through a mailed questionnaire. Results from a series of covariance structure models indicated that a partially mediated model was the best fitting model, chi2 = (255, N = 253) 461.20, p <. 001; root mean error of approximation = . 05; comparative fit index = .95; parsimonious normed fit index = .71. In partial support of the study hypotheses, the results supported full mediation of the direct effect from organizational support to life satisfaction. Work-family conflict partially mediated the relationship between organizational support and job satisfaction. Job satisfaction partially mediated the effect of organizational support and work-family conflict to life satisfaction.  相似文献

The developmental trajectory of perceptual organization in humans is unclear. This study investigated perceptual grouping abilities across a wide age range (8–30 years) using a classic compound letter global/local (GL) task and a more fine-grained microgenetic prime paradigm (MPP) with both few- and many-element hierarchical displays. In the GL task, contrary to adults, both children and adolescents exhibited a classic local bias. In the MPP, all 3 age groups evinced a bias to individuate the few-element displays; however, the ability to encode the global shape of the many-element displays at the short prime durations increased with age. These results indicate that the full process of garnering shape information from perceptual grouping, which is essential for the ability to do fast and efficient object recognition and identification, develops late into adolescence.  相似文献

48 1- and 48 2-year-olds were observed in groups of 3 for 25 min on 2 consecutive days, once with ample resources and once with scarce resources. The triads were composed of either 2 girls and a boy or 2 boys and a girl, and duplicate copies of toys were available for half the groups. Their conflicts contained interpersonal features and were more affected by social influences than by the availability of resources. Contrary to expectations, scarcity of resources did not result in increased conflict. In fact, 2-year-olds were more likely to resolve conflict by sharing when toys were scarce. The provision of duplicates decreased the probability of conflict, but many conflicts occurred even when a duplicate was easily accessible. The form of conflict depended on the children's age and the gender composition of the group. Older children and groups dominated by boys, relative to younger children and groups dominated by girls, were less likely to use force and more likely to resolve disputes in prosocial ways. Taken together, these findings provide further evidence for the social nature of conflict in the first few years of life.  相似文献

This study examined the nature of social conflict occurring spontaneously during children's play. Preschoolers' (mean age = 53.9 months) differential conflict behavior with their friends and acquaintances was analyzed by use of relationship status as a within-subjects factor. Children behaved differently when interacting with their friends than they did with acquaintances. Conciliatory gestures (e.g., compromise, apology) were used more often with friends than with acquaintances. Conciliatory gestures were more likely than yields to lead to peaceful outcomes. However, yields were used most often by the children. Yet, no matter what resolution strategy was used, friends were more likely to remain together after conflict than acquaintances were. Because friendships are important to them, children must learn ways to maintain interaction despite conflict. Conflict resolution strategies among peers begin to emerge in the preschool years, first within friendly relationships. It is suggested that rather than using direct intervention, teachers should indirectly facilitate the development of such strategies.  相似文献

Abstract

This study aimed to evaluate the autonomic modulation of heart rate in sedentary paraplegics and paraplegic wheelchair basketball players with thoracic spinal cord injury below T6. Seven paraplegic wheelchair basketball players (active paraplegic group), five paraplegics who were not involved in regular exercise (sedentary paraplegic group) and 10 able-bodied participants (control group) took part in the study. The heart rate variability was evaluated by linear (low frequency and high frequency band in normalised units and low frequency/high frequency ratio) and nonlinear methods (Shannon entropy, corrected conditional entropy, and symbolic analysis).

The sedentary group presented significantly higher values for low frequency, low frequency/high frequency ratio and symbolic index with no significant variations (0V%), and also lower values for the high frequency and symbolic index with two significant unlike variation (2ULV%) compared to active paraplegic group. Shannon entropy and corrected conditional entropy analyses revealed significantly lower values in the sedentary group than in the control or active paraplegic groups. Paraplegic individuals who regularly undertake physical exercise have higher complexity of R-R interval time series, lower sympathetic modulation, and higher parasympathetic modulation than sedentary paraplegic participants.  相似文献

Background:Few electronic resources are available for new mothers with concerns about changes in their pelvic floor following childbirth. Patients may struggle when seeking authoritative information regarding pelvic floor conditions online given the sensitivity of the topic as well as the inadvertent connection to obscene or demeaning content found online. A health sciences librarian partnered with the Motherhood and Pelvic Health Study, an interdisciplinary research group, to provide expert searching skills for a particularly challenging health condition that patients struggle to find useful information on.Case Presentation:A custom rubric was developed to evaluate existing information products, which included criteria for cultural sensitivity, conflicts of interest, and other red flags. This evaluation process enabled the research team to identify top-tier evidence-based materials that were culturally congruent. This collaborative evaluation process led to the creation of a web-based toolkit resource for new mothers concerned about changes in their pelvic floor. The toolkit connects women to pertinent information on a national health organization''s patient portal, supplemented by videos created by the team to serve as models of communication for women and health care providers.Conclusion:When developing a web-based resource, health sciences libraries can partner with research teams to find, evaluate, and disseminate information. Culturally congruent toolkits such as this one can improve access to health information and lead to improved health outcomes. To ensure that the information highlighted in toolkits is both culturally congruent and authoritative, research teams should form advisory committees and partner with relevant professional medical associations.  相似文献
