社会体育指导与管理本科专业课程设置探析简

通过文献资料法,对2013年8月申报社会体育指导与管理专业的9所高校本科课程设置现状与问题进行分析,以期提高本专业的人才培养质量。结果表明,各院校的人才培养方案专业必修课和选修课能够满足教育部对本专业课程的规定,但部分院校选修方向与职业联系不密切;选修方向课程学分均不超过总学分比例的10%,不能满足就业需求;课程开设时期普遍偏晚,不利于专业职业技能的形成。建议专业方向课程应与职业教育密切相连,并满足职业教育的需求。     

Daphne: a new multimetric benthic index for the quality assessment of marine coastal environment in the Northern Adriatic Sea

A new benthic index, named Daphne, is proposed for the Northern Adriatic coastal area, near the Po river delta. It is based on six characteristics of the community that do not require in-depth taxonomic expertise: number of mollusc species, % of bivalves, % of polychaetes, abundance of the opportunistic species Corbula gibba, % of amphipods and number of ‘typical mollusc species’ that are individuated by multivariate analysis. The application of the index in selected stations along a gradient of decreasing disturbance shows that it is simple to use in regular monitoring campaigns and that the results are consistent with environmental quality data in the special conditions of this area subjected to considerable river runoff. The index can be used in addition and as a complement to more widespread indices (such as M-AMBI); a comparison of the two indices performance is discussed.     

Uncovering context-induced status quo effects in choice experiments

In this study five design dimensions are varied systematically investigating context-induced status quo effects in choice experiments. Additionally, two structural complexity measures, entropy and the number of attribute level changes, are used to capture status quo effects from the similarity between alternatives and the number of trade-offs. A crucial finding is that the frequency of status quo choices is negatively associated with the number of alternatives indicating preference matching effects. By contrast, the probability of choosing the status quo increases with a higher number of choice tasks, a wider level range, and the similarity between alternatives. Status quo choices are further affected by the current environmental situation perceived by respondents. We also find that marginal and non-marginal welfare estimates are significantly affected by the choice design. One key finding is that the most used choice task format in environmental economics, i.e., two hypothetical and a status quo alternative, is likely to increase the propensity to choose the status quo option.
