The teaching of decision sciences presupposes that careful attention is directed toward improving students' critical thinking and analytical skills. This paper presents an approach to teaching quantitative methods classes that focuses on developing student skills in the areas of analytical and critical thinking through written and oral communication. The approach requires very little additional instructor preparation time and does not require the instructor to make major changes in either the content or organization of the course. While the instructor's investment is minimal, the benefits to the students appear to be substantial. 相似文献

Urbanization and development are predicted to increase considerably in the United States over the next several decades, and
this is expected to result in large-scale habitat loss, fragmentation and loss of wildlife species. Thus, natural parks and
preserves are becomingly increasingly important in the conservation of regional biodiversity. We used mist-nets and AnabatII
acoustic detectors to survey bats in 10 national parks in the southeastern U.S. and examined the relationship between bat
community structure and development in the surrounding 5 km. We predicted that species richness would increase with park size
and that species richness and evenness would decrease with development. Species richness was not related to development or
any other landscape characteristics including park size. In contrast, species evenness declined with increasing development.
Percent Developed land in the surrounding 5 km area was the only variable that entered into the stepwise regression model.
The decrease in species evenness in the urban parks was due to the dominance of big brown bats (Eptesicus fuscus) in these parks. The percentage of big brown bats in our captures was positively related to percent Developed land in the
surrounding area. Our data suggest that urban parks may be important for conserving regional bat biodiversity. However, the
low species evenness in these parks suggests that some bat species may be susceptible to the effects of urbanization and may
be extirpated over time. Thus, management of urban as well as rural parks should strive to conserve as much bat roosting and
foraging habitat as possible. 相似文献

Abstract Objective: Social norms campaigns are a cost-effective way to reduce high-risk drinking on college campuses. This study compares effectiveness of a “standard” social norms media (SNM) campaign for those with and without exposure to additional educational sessions using audience response technology (“clickers”). Methods: American College Health Association's National College Health Assessment questions are used to evaluate actual and perceived use. Additional survey questions assess individual exposure to the interventions. Results: The authors find “clicker” technology to be more effective than social norms poster media alone in reducing misperceptions of normative alcohol use for those students who attended clicker sessions. Conclusion: Poster SNM campaigns may be most effective when supported by group “clicker” heath-related sessions. 相似文献

During the week after the United States’ raid on Osama bin Laden’s compound in Abbottabad, Pakistan, in May 2011, the media discussed women associated with the raid. Media reported that bin Laden hid “behind a woman” during the raid, describing bin Laden’s wife as a human shield. The press also discussed a photo of the Situation Room during the raid, calling attention to Hillary Clinton, who was thought to be gasping out of emotion in the photo. The narratives surrounding Amal Ahmed al-Sadah (married to bin Laden) and Secretary Clinton elicit insights into the place of gender vis-à-vis terrorism. In this paper, we content analyze non-op-ed newswires, debating how/whether the media framed al-Sadah and Clinton as political agents, feminine representations, and/or as superfluous to terrorism. We find that the press described Clinton as emotional and largely saw al-Sadah as passive and generically as a wife. Women were portrayed differently than men, who are considered active, but unemotional. Additionally, articles critiqued President Obama’s posture and clothing in the Situation Room and disparaged Osama bin Laden for unmanliness. We therefore conclude that the mainstream, print media press prioritizes hegemonic masculinity when discussing terrorism, overlooking women’s agency and ascribing feminine identities to women and marginalized masculinities to certain men. 相似文献

This study investigated Korean-American adolescents' stress related to their acculturation experiences and mental health. A total of 260 Korean-American adolescents from immigrant families (ages 12–18 years) participated in the study. The U.S. born group had a higher level of acculturative stress than the Korea-born group (t = 2.222; df = 258; p < .05). Males reported a higher level of self-esteem than females (t = ?2.112; df = 257; p < .05). Acculturative stress was positively correlated with depression (r = .299; p < .01) and negatively related to self-esteem (r = ?.292; p < .01). Self-esteem was negatively related to depression (r = ?.536; p < .01). 相似文献

出生性别比综合治理:有所为,有所不为 总被引:3,自引:0,他引:3
从1980年我国出生性别比越过正常值域至今,党和各级政府制订了种种措施进行综合治理,但取得的成效甚微。这一时期我国治理工作的特点有:重视禁止性法律法规的制定,但与之相配套的规章制度比较缺乏;重视目标任务的提出,但落实目标的措施比较缺乏;部门性、专项性规章制度较多,综合性规章制度比较缺乏。今后一段时期内综合治理工作,可以按照避实就虚、避难就易的原则,在大力发展社会经济、建立健全社会养老制度、相关法律法规的制定与完善、加大对两非行为的打击力度等方面有所作为;而在人口生育政策的调整、传统文化的改变等方面有所不为。 相似文献
