B. Lamar Johnson 《College Teaching》2013,61(2):73-76
Although interdisciplinary efforts in teaching and research are promoted as a possible antidote to increasing disciplinary separatism in colleges and universities, evaluations of interdisciplinary efforts in the classroom, particularly those spanning the traditional science-humanities divide, are not frequently documented. This article describes the development, execution, and assessment of a unique effort in interdisciplinary teaching in which four doctoral candidates from widely varying home disciplines collaborated to create and teach a “truly interdisciplinary” course for first-year students centered on the pervasiveness of humankind's quest for immortality. Assessment of the course indicates several desirable student outcomes, including the development of a more mature world view and appreciation for different epistemologies, which recommend the continuation of this and similar interdisciplinary efforts. While students at times found the enormous number of disciplines potentially related to the central topic overwhelming, at the conclusion of the course, they largely identified the exposure to new perspectives as an exciting and worthwhile academic experience. Similar interdisciplinary efforts in the classroom are encouraged, though ample course development time is recommended to maximize success. 相似文献

Response rates, response time, and costs of mail and electronic surveys were compared. The survey sample consisted of college faculty in the southeastern United States. Mail surveys yielded a higher response rate and a lower rate of unde-liverable surveys. However, receipt of responses was significantly quicker for those delivered electronically, with over 80% of initial responses arriving before receipt of the 1st returned mail survey. The costs associated with distribution of surveys and preparation of data for analysis were much lower with the electronically delivered surveys. 相似文献

Sedentary behaviour (SB) has recently emerged as an independent risk factor for different health outcomes. Older adults accumulate long time in SB. Understanding the role that SB plays on health is crucial for a successful aging. This short systematic review summarizes the current evidence related to the effects of objectively measured SB on frailty, physical performance and mortality in adults ≥60?years old. The literature search produced 271 records for physical performance (n?=?119), frailty (n?=?31), and mortality (n?=?121). Finally, only 13 articles fulfilled the inclusion criteria and were included in this review. All articles but one included in the physical performance section (n?=?9) showed a negative association between longer time spent in SB and physical performance. A significant association of SB with higher odds of frailty was found, however this association disappeared after adjusting for cognitive status. Lastly, two of the three included studies showed positive associations between SB and mortality, but this effect decreased or even disappeared in the more adjusted models. In conclusion, there is consistency that SB is negatively associated with physical performance. However, the relationship between objectively measured SB and frailty incidence and mortality rates remains unclear and deserves further research. The use of homogenous criteria to assess SB and the inclusion of more robust research designs will help clarifying the independent effects that SB could have on physical performance, frailty, and mortality. This will ultimately help designing more efficient and comprehensive physical activity guidelines for older adults. 相似文献

对房产持有环节开征房产税具有国际通用的合理性和合法性,房产税改革是新一轮国家财税体制改革的重要内容。对国内主要城市的房产税改革方案及其财税效应分析表明:采用无差别税率征税方案的优势在于减少征管成本、确保居民纳税义务的公平性,劣势在于造成纳税人税负过重、不利于调节财富分配差距;而按住房面积采用递进税率征税方案的优势在于能够调节贫富差距、体现“量能负担”原则,劣势在于容易被纳税人投机取巧而逃避高税率和监管。权衡利弊,“每人享受一定面积的减免,根据住房面积大小、基于公告价值或评估价值按不同税率征收”的方案,可作为今后房产税改革的主要方向。 相似文献

This paper looks at the issue of access to the arts in terms of the very unequal attendance at and audiences for the high arts by educational grouping. The meaning of equal access is analysed, recent data for two countries, namely the United States and Ireland, are examined and new evidence is proffered. The constraints/barriers to, and the rationale for, more equal attendance/audiences are examined. The paper concludes by outlining a number of possible responses to this continuing problem.This paper was presented at the 9th international conference of the Association for Cultural Economics, held in Boston, May 8–11, 1996. 相似文献
