Abstract Female athletes are considered to exhibit knee and trunk motion that is characteristic of anterior cruciate ligament (ACL) injury. The aim of this study was to examine the in vivo motion of the trunk and knee during a cutting manoeuvre and determine the relationship between them. All participants (10 male and 10 female college athletes) performed a shuttle run cutting task with the left limb. Trunk inclination (forward and lateral) and knee joint angles (flexion/extension, abduction/adduction, and internal/external tibial rotation) were calculated. Differences between the sexes and associations between knee motion and trunk inclination were examined. An increase in trunk forward inclination was strongly correlated with an increase in knee flexion angle and moderately correlated with a decrease in the excursion of internal tibial rotation. An increase in right trunk lateral inclination was moderately correlated with an increase in excursion of internal tibial rotation. The results also showed differences between the sexes in trunk forward inclination, lateral inclination, and knee flexion angle, but no such differences in knee abduction or internal tibial rotation. Trunk inclination is related to knee flexion and excursion of internal tibial rotation. Female athletes demonstrate a low trunk forward inclination and knee flexion angle, a posture that resembles that of ACL injury. 相似文献

Anatomy education often consists of a combination of lectures and laboratory sessions, the latter frequently including surface anatomy. Studying surface anatomy enables students to elaborate on their knowledge of the cadaver's static anatomy by enabling the visualization of structures, especially those of the musculoskeletal system, move and function in a living human being. A recent development in teaching methods for surface anatomy is body painting, which several studies suggest increases both student motivation and knowledge acquisition. This article focuses on a teaching approach and is a translational contribution to existing literature. In line with best evidence medical education, the aim of this article is twofold: to briefly inform teachers about constructivist learning theory and elaborate on the principles of constructive, collaborative, contextual, and self‐directed learning; and to provide teachers with an example of how to implement these learning principles to change the approach to teaching surface anatomy. Student evaluations of this new approach demonstrate that the application of these learning principles leads to higher student satisfaction. However, research suggests that even better results could be achieved by further adjustments in the application of contextual and self‐directed learning principles. Successful implementation and guidance of peer physical examination is crucial for the described approach, but research shows that other options, like using life models, seem to work equally well. Future research on surface anatomy should focus on increasing the students' ability to apply anatomical knowledge and defining the setting in which certain teaching methods and approaches have a positive effect.

The main goals of e-government are to increase agency efficiency and offer benefits to citizens. These goals have often been addressed as two interplaying outcomes of public e-service development, which are possible to achieve in parallel. This article shows that the two frequently applied stakeholders of e-government (agencies and citizens) are much too extensive and heterogeneous in order to be meaningfully addressed in public e-service conceptualization and development. We conduct a stakeholder centered analysis of a public e-service development and implementation process in order to identify stakeholder groups and discuss how they differ in their perceptions and, consequently, also in their feelings of relevance and need related to the e-service. By adopting a multi-faceted perspective on stakeholders, public e-service development can be analyzed and understood in a way that takes several stakeholder groups into account. Our study contributes with deeper insights about a situation where stakeholder salience changes over time, while some stakeholder groups have low salience during the entire process. The result of conducting a stakeholder centered analysis is that we, by visualizing the stakeholder groups' differences, are better prepared to meet and combine different needs related to a planned e-service. Thus, we argue that a stakeholder centered analysis of expectations and opinions concerning the e-service help to develop e-services possible to succeed in offering both external service and internal efficiency. 相似文献

This article compares outcomes in the Norwegian labour market for non-Western immigrants and majority colleagues with professional or master’s degrees within three different fields of study: health science, social science and natural science. Professions have a higher degree of occupational closure, which may entail that non-Western immigrants with relevant educations achieve economic parity with the majority. Comparing employment rates and income equality among professionals and others with a master’s degree tests whether the professions in each field yield more egalitarian outcomes. The fields are analysed separately and the results show that a professional degree in natural science or social science has no equalising effect. Education leading to a health profession provides immigrants with a ‘labour market shelter’. 相似文献

This study entailed a 3 (instructional intervention) × 2 (assessment-type) between-subjects experimental design employing a pretest-intervention-posttest methodology. The instructional interventions were administered between subjects in three conditions: (a) dynamic instruction, (b) triarchic or theory of successful intelligence-control instruction, and (c) standard-control instruction. The assessment-type consisted between subjects of either (a) a group-administered dynamic posttest or (b) the same group-administered posttest interspersed with a control filler activity. Performance in different mathematics content areas taught in fourth grade was investigated. In total, 1,332 students and 63 classroom teachers in 24 schools across six school districts participated in the study. The results indicate the advantages of using dynamic instruction and assessment in regular classrooms while teaching mathematics, especially when the student body is highly ethnically diverse. 相似文献

Research in the sociology of education argues that the educational system provides different learning opportunities for students with different socioeconomic backgrounds and that this circumstance makes the educational process an important institutional context for the reproduction of educational inequality. Using combined survey and register data for more than 56,000 students in 825 schools, this article conducts the first empirical test of the argument that instructional strategies which emphasize student responsibility and activity, also referred to as student-centered instruction, increase educational inequality. We analyze whether the impact of student-centered instructional strategies on academic achievement differs for students with different socioeconomic backgrounds. Results suggest that a student-centered instructional strategy has a negative impact on academic achievement in general, and for students with low parental education in particular. Our findings support the argument that the instructional strategy of schools is an important mechanism in generating educational inequality through the stratification of learning opportunities. 相似文献

AbstractEvidence suggests that periods of heavy intense training can result in impaired immune cell function, and whether this leaves elite athletes at greater risk of infections and upper respiratory symptoms (URS) is still debated. There is some evidence that episodes of URS do cluster around important periods of competition and intense periods of training. Since reducing URS, primarily from an infectious origin, may have implications for performance, a large amount of research has focused on nutritional strategies to improve immune function at rest and in response to exercise. Although there is some convincing evidence that meeting requirements of high intakes in carbohydrate and protein and avoiding deficiencies in nutrients such as vitamin D and antioxidants is integral for optimal immune health, well-powered randomised controlled trials reporting improvements in URS beyond such intakes are lacking. Consequently, there is a need to first understand whether the nutritional practices adopted by elite athletes increases their risk of URS. Second, promising evidence in support of efficacy and mechanisms of immune-enhancing nutritional supplements (probiotics, bovine colostrum) on URS needs to be followed up with more randomised controlled trials in elite athletes with sufficient participant numbers and rigorous procedures with clinically relevant outcome measures of immunity. 相似文献
