The acculturation process generally contributes greatly to stress and anxiety levels among international students. The objectives of the present study were: (1) to see whether international students experience more anxiety, irritability, and stress from being apart from family and friends, pressure from school, difficulties with language, work and finances than students with permanent US residency, and (2) to investigate the same stressors in groups within the international student population. Surveys were distributed to 246 students aged 17–51 at an ethnically diverse community college in Southern California, US. Analysis of variance was conducted to investigate group differences between students: permanent US residents vs. international students, and, permanent US residents vs. European and Asian students, respectively. No significant differences were found between international students and students with permanent US residency. However, when the international student population was sub-grouped by above cultural regions a different pattern emerged. Difficulties of not being able to work and of socially related problems were perceived as more severe for the European and the Asian groups, while finance problems were hard for all three groups. The variable of language difficulties was harder for Asian students, while that of stress of being apart from family was harder for students from Europe. Findings are not only congruent with prior research results on international students but also demonstrate that international students with culturally diverse needs should not be considered as one homogenous group. It is suggested that educational systems need to properly adapt in order to accommodate international students’ unique cultural needs.  相似文献

The Neurobehavioral Assessment of the Preterm Infant was developed in 3 phases: a pilot study, an exploratory study, and a validation study. In the exploratory study, clusters characterized by conceptual cohesion and face validity were systematically subjected to statistical analyses to determine whether they also had high test-retest reliability and developmental validity. In the validation study, a shortened version of the test was used with an independent cohort of 290 preterm infants. A step-by-step methodological process was used to test whether the results from the exploratory study would generalize over cohorts, different versions of the test, different hospitals, and changes in examiners. This process yielded 7 highly stable, developmentally valid, and representative preterm neurobehavioral functions that generalized over the exploratory and the validation studies. These were: motor development and vigor, scarf sign, popliteal angle, alertness and orientation, percent asleep ratings, irritability, and vigor of crying.  相似文献

In this study, we use data from the 1999 National Study of Postsecondary Faculty (NSOPF:99) to measure the unexplained wage gap between men and women in academe. We pay particular attention to how these unexplained wage gaps have changed over time by comparing the results from the 1999 survey to published results from previous national surveys and test for the sensitivity of these findings to the method used for measuring the unexplained wage gap and the type of institution or field being examined. We found that there has been a notable reduction in the overall unexplained wage gap between men and women, and that there is no longer any evidence of a statistically significant pay differential between men and women in doctoral-level or liberal arts institutions. The results also show that significant pay differentials still persist in some segments of academe, and that overall women with comparable qualifications to men have lower salaries.Earlier versions of this paper were presented at the annual meetings of the Association for Institutional Research, Tampa, FL, May 2003, and the Association for the Study of Higher Education, Portland, OR, November 2003.  相似文献

There are widespread aspirations to focus undergraduate biology education on teaching students to think conceptually like biologists; however, there is a dearth of assessment tools designed to measure progress from novice to expert biological conceptual thinking. We present the development of a novel assessment tool, the Biology Card Sorting Task, designed to probe how individuals organize their conceptual knowledge of biology. While modeled on tasks from cognitive psychology, this task is unique in its design to test two hypothesized conceptual frameworks for the organization of biological knowledge: 1) a surface feature organization focused on organism type and 2) a deep feature organization focused on fundamental biological concepts. In this initial investigation of the Biology Card Sorting Task, each of six analytical measures showed statistically significant differences when used to compare the card sorting results of putative biological experts (biology faculty) and novices (non–biology major undergraduates). Consistently, biology faculty appeared to sort based on hypothesized deep features, while non–biology majors appeared to sort based on either surface features or nonhypothesized organizational frameworks. Results suggest that this novel task is robust in distinguishing populations of biology experts and biology novices and may be an adaptable tool for tracking emerging biology conceptual expertise.  相似文献

The current study examined the associations between television and movie use, romantic ideals (belief in love conquers all and soul mates), and relationship satisfaction among adults who were currently in romantic relationships. Participants were 306 individuals aged 18–64. They were asked about their media use, their romantic beliefs, and their current relationship. In addition to overall time spent watching television and movies, seven specific genres were measured. Results indicated that viewing each genre of television and movie analyzed (including relationship reality TV, TV drama, TV comedy, soap opera, and romantic movie) was positively associated with romantic ideals. The results for television were not in the hypothesized direction or consistent with prior studies. Television drama and romantic movie viewing were the strongest predictors of belief in love conquers all and relationship satisfaction, whereas soap opera viewing was the strongest predictor of belief in soul mates. None of these associations were moderated by age or relationship length. Mediation analyses also showed that specific genres of viewing were positively associated with relationship satisfaction via romantic ideals. The implications of viewing television and movies for adults’ romantic relationships are discussed.  相似文献
