国外学分互认制度对我国中高职与开放教育衔接的启示   总被引:1,自引:0,他引:1  
澳大利亚国家资格框架下职业教育与普通教育体系互通及学分互认、欧洲ECTS和ECVET的学分计量与评定制度以及美国的学分互认及课程衔接模式都为我国中高等职业教育和开放教育的纵向衔接提供了重要参考。我国应发挥政府的推动作用,通过明确学分互认的依据、对中高职与开放教育进行一体化设计、建立国家课程等措施来推动中高职与开放教育学习成果的认证。  相似文献

Objective:In 2018, the Network of the National Libraries of Medicine (NNLM) launched a sponsorship program to support public library staff in completing the Medical Library Association''s Consumer Health Information Specialization (CHIS). The objectives of our study were to: (1) determine whether completion of the sponsored specialization improved ability to provide consumer health information; (2) identify new health information services, programming, and outreach activities at public libraries; (3) investigate benefits of the specialization; and (4) determine the impact of sponsorship on obtaining and continuing the specialization.Methods:We used REDCap to administer a 16-question survey in August 2019 to 224 public library staff who were sponsored during the first year of the program. We measured competence in providing consumer health information aligned with the eight Core Competencies for Providing Consumer Health Information Services [1] as well as new activities at public libraries, benefits of the specialization to public library staff, career gains, and the likelihood of continuing the specialization based on funding.Results:More than 80% of 136 participants reported an increase in core consumer health competencies, with a statistically significant improvement in mean competency scores after completing the specialization. Ninety percent of participants have continued their engagement with NNLM, and more than half offered new health information programs and services. While more than half planned to renew the specialization or obtain the Level II specialization, 72% indicated they would not continue without NNLM sponsorship.Conclusions:Findings indicate that NNLM sponsorship of the CHIS specialization was successful in increasing the capacity of public library staff to provide health information to their communities.  相似文献

在价格敏感型随机需求的闭环供应链中,分析了集中式决策和三种分散式回收渠道下系统的最优决策,探讨了不同的回收成本结构对系统决策以及回收渠道选择的影响。数值仿真的结果表明:无论在何种回收渠道下,与成本规模不经济的情形相比,规模经济时最优回收率更高,成员从再制造中获益更大。当成本结构规模经济时,零售商回收效率最高;而当成本结构规模不经济时,制造商回收效率最高。提出二部定价契约对分散式供应链进行协调。  相似文献

In the early twentieth century, fatigue research marked a site of conflicting scientific, industrial, and cultural understandings of working bodies. Many fatigue researchers understood fatigue to be a physiological fact and allied themselves with Progressive-era reformers in urging industrial regulation. Reformers clashed with advocates of Taylorism, who held that productivity could be perpetually increased through managerial efficiency. Histories of this conflict typically cease with the end of the First World War. I examine the work of the Harvard Fatigue Laboratory in the 1920s and 1930s to explore the impact that the introduction of biochemical methods had on the relationship between science and reform. The Laboratory developed sophisticated techniques to study the blood of exercising individuals. In particular, it found that exercising individuals could attain a biochemically "steady state," or equilibrium, and extrapolated from this to assert that fatigue was psychological, not physiological, in nature. In contrast to Progressive-era research, the Laboratory reached this conclusion through laboratory examination, not of workers, but of Laboratory staff members and champion marathon runners. I present the Laboratory's institutional history, scientific work, and finally how common cultural understandings of athletes and work lent plausibility to its efforts to make authoritative statements about industrial conditions.  相似文献

The aim of this study was to compare the somatotype and size of elite female basketball players in terms of playing position and team performance. Anthropometry and somatotype data were collected on 168 players from 14 countries before the Women's World Basketball Championship, Australia, 1994. There were 64 guards (mean?±?s: age 25.4?±?3.3 years, height 1.72?±?0.06?m, mass 66.1?±?6.2?kg, somatotype?=?2.9?–?3.9?–?2.6), 57 forwards (age 25.2?±?3.8 years, height 1.81?±?0.06?m, mass 73.3?±?5.9?kg, somatotype?=?2.8?–?3.5?–?3.2) and 47 centres (age 24.1?±?3.1 years, height 1.90?±?0.06?m, mass 82.6?±?8.2?kg, somatotype?=?3.2?–?3.1?–?3.4). Mean somatotypes by position were significantly different (F?=?7.73, P?<?0.01). Guards had greater mesomorphy than centres and less ectomorphy than forwards and centres. When discriminant function analysis was applied to endomorphy, mesomorphy, ectomorphy, age, height and mass, only height, mass and ectomorphy entered (Wilks' λ?=?0.351, F?=?31.40, P?<?0.000), 70% of the variance was accounted for, and 72% of players were correctly classified. In the four top versus four bottom teams, guards were taller and more ectomorphic, forwards were taller, with lower mesomorphy and higher ectomorphy, and centres did not differ. Thus there are some differences in somatotypes by position and team placing, but the combination of height, mass and ectomorphy provide the best differentiation by position.  相似文献

Historically, research focusing on rater characteristics and rating contexts that enable the assignment of accurate ratings and research focusing on statistical indicators of accurate ratings has been conducted by separate communities of researchers. This study demonstrates how existing latent trait modeling procedures can identify groups of raters who may be of substantive interest to those studying the experiential, cognitive, and contextual aspects of ratings. We employ two data sources in our demonstration—simulated data and data from a large‐scale state‐wide writing assessment. We apply latent trait models to these data to identify examples of rater leniency, centrality, inaccuracy, and differential dimensionality; and we investigate the association between rater training procedures and the manifestation of rater effects in the real data.  相似文献
