从信任结构理论的角度看,传统中国是一个人格信任的社会,由此决定了适用于其中的法律的伦理化品性。只有对这些特点有了明确的把握以后,在中国社会与法律的现代化转型中,我们才能获得更为明晰的前进方向和出路:建立系统信任为主导的社会结构和形式化的法律制度。 相似文献

National content standards in PE address responsibility; however, learning outcomes and teacher effectiveness in this area remain poorly defined. This study employed the Social and Emotional Learning framework and a teaching personal and social responsibility (TPSR) model fidelity instrument to address this gap. Our purpose was to examine the utility of the Tool for Assessing Responsibility-based Education (TARE) in assessing teacher effectiveness promoting responsibility. We conducted a comparative case study of three PE teachers in an urban public high school. Data sources included observations, interviews, and artifacts. Findings indicate that the TARE is a feasible instrument to assess PE teachers’ effectiveness in promoting responsibility. Data were sufficient to develop distinct teacher profiles. While the TARE is a TPSR fidelity instrument, it is also a valid and reliable observation instrument that can be applied in the context of practice. Implications for professional development and research are discussed. 相似文献

To evaluate the value of ultrasonography in the diagnosis of anterior cruciate ligament injury (ACL injury) by conducting a systematic review and meta-analysis. A literature search was carried out in the Cochrane Library, Embase, Pubmed databases and included studies prior to April 2017. Based on inclusion and exclusion criteria, studies evaluating ultrasound to diagnose ACL injury were selected. MRI, arthroscopy and clinical-follow were considered the reference standards. The diagnostic accuracy of ultrasound was assessed using a combination of sensitivity, specificity, likelihood ratio (LR), post-test probability, diagnostic odds ratio (DOR) and by summarizing the area under the receiver operating characteristic (SROC) curve. A total of 4 studies involving 246 patients were eventually included in the analysis. In these four studies, the combined sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, post-test probability and DOR were 90.0% (95% CI: 77–96), 97% (95% CI: 90–99), 31.08 (95% CI: 8.75–110.41), 0.11 (95% CI: 0.05–0.24), 89% (3%) and 288.81 (95% CI: 78.51–1062.48), respectively. The area under the SROC curve was 0.98 (95% CI: 0.97–0.99). Our meta-analysis showed that ultrasound can play an important role in the diagnosis of ACL injury. Because of its high sensitivity, high specificity and high diagnostic ability, ultrasound should be a part of the standard diagnostic work-up of an ACL injury. 相似文献

We investigated the quality of work-integrated learning (WIL) assessment design in higher education programmes, through review of peer-reviewed studies published internationally and in English, 1990–2015. Such a review is timely in light of vested interests from a range of WIL stakeholders; high-level endorsement of WIL across university programmes; a regulatory environment requiring development and assurance of higher-order learning outcomes; and a WIL assessment literature that identifies a number of challenges and opportunities. We searched six electronic databases, yielding 20 intervention studies that met inclusion criteria. Findings reveal high-quality assessment design, albeit a need for greater involvement of industry/professional partners in assessment practices and stronger alignment between reflective assessment tasks and students' WIL experiences. The evidence base under review largely comprised qualitative and mixed methods studies, with the indication that the quality of the study design had improved over time, although variably across disciplinary fields. The key recommendation from this review is that resources are needed to support research-active WIL academics, partners and students to: (a) design and participate in assessment practices, which promote integration of student learning, across university and work settings, and achievement of higher-order learning outcomes and (b) pursue a collaborative research agenda involving robust evaluation research, inclusive of quantitative studies. 相似文献

提出了带形状参数的n次Wang-Ball调配函数,它是n次Wang-Ball基函数的扩展,它具有与n次Wang-Ball基函数相似的性质。基于给出的调配函数,构造了带形状参数的多项式曲线。参数λ具有明确的几何意义,当λ增大时,曲线将逼近于控制多边形,当λ=0时,即退化为n次Wang-Ball调配函数,它为曲线设计提供了一种有效的方法。 相似文献
