International students continue to grow in number worldwide, prompting researchers to look for ways to make the study abroad experience more fruitful. One avenue of research has focused on friendship formation, the significant role it plays in the study abroad experience, and the unique friendship combinations made possible by the study abroad experience. International students form friendships with individuals from their own country, from other countries, and from the host country. Research has found that international students often have more friends from their home country; however, research has also demonstrated a relationship between having more host country friends and satisfaction, contentment, decreased homesickness, and social connectedness. The current study looks to further explore these relationships through a social network lens by examining friendship network ratios, strength, and variability of the three friendship groups. A friendship network grid was developed to assess where international students’ friends are from and how strong those friendships are. Eighty four international students completed a survey examining the relationship between friendship networks, social connectedness, homesickness, contentment, and satisfaction. Contrary to prior research, international students did not report having a higher ratio of individuals from their home country in their friendship networks. However, international students with a higher ratio of individuals from the host country in their network claimed to be more satisfied, content, and less homesick. Furthermore, participants who reported more friendship variability with host country individuals described themselves as more satisfied, content, and more socially connected. Implications and directions for future research are discussed.  相似文献

The aim of this study was to understand adolescent mothers’ childbirth experiences. Semistructured interviews were conducted with participants recruited from a community-based program for adolescent mothers. Fourteen mothers described their birth experiences. Using a narrative analytic approach, responses were reconstructed into birth stories. Stories, condensed into poetic form, were compared and contrasted. Four unique categories emerged: connected births, surreal births, disconnected births, and disempowered births. Categories differed by agency, support, and emotional tone. Positive support was found in stories that portrayed high agency and positive affect, whereas problematic support was apparent in stories that conveyed passivity, frustration, and disappointment. This study has implications for tailoring childbirth education for adolescent mothers and can inform health-care professionals working with this population.  相似文献

This study was designed to (a) test the psychometric properties of a new observation measure of developmentally appropriate classroom practices in kindergarten through third-grade classrooms, and (b) determine how well classroom and teacher characteristics predict developmentally appropriate classroom practices. Teacher-reported and observational data from 69 classrooms provided support for construct validity, internal consistency, and interrater agreement of the Assessment of Practices in Early Elementary Classrooms (APEEC) measure. Hierarchical multiple regression analyses indicated that classroom characteristics (grade, class size, number of children with disabilities), teacher characteristics (education level, years of experience) and teacher beliefs (developmentally appropriate beliefs and developmentally inappropriate beliefs) accounted for 42% of the variance in observed classroom practices. With all variables in the model, teacher education, grade, and beliefs in developmentally appropriate and inappropriate practice accounted for most of the variance in observed classroom practices.  相似文献

The Internet has created new opportunities for librarians to develop information systems that are readily accessible at the point of care. This paper describes the multiyear process used to justify, fund, design, develop, promote, and evaluate a rehabilitation prototype of a point-of-care, team-based information system (PoinTIS) and train health care providers to use this prototype for their spinal cord injury and traumatic brain injury patient care and education activities. PoinTIS is a successful model for librarians in the twenty-first century to serve as publishers of information created or used by their parent organizations and to respond to the opportunities for information dissemination provided by recent technological advances.  相似文献

The aims of this study were to: (1) determine whether the number of pedometer counts recorded by adolescents differs according to the adiposity of the participant or location on the body; (2) assess the accuracy and reliability of pedometers during field activity; and (3) set adolescent pedometer-based physical activity targets. Seventy-eight 11- to 15-year-old Boy Scouts completed three types of activity: walking, fast walking and running. Each type was performed twice. Participants wore three pedometers and one activity monitor during all activities. Participants were divided into groups of normal weight (BMI < 85th percentile) and at risk of being overweight (BMI > or = 85th percentile). Intra-class correlations across the three activities indicated reliability (r = 0.51 - 0.92, P < 0.001). This conclusion was supported by narrow limits of agreement that were within a pre-set range that was practically meaningful. Multivariate analysis of covariance indicated adiposity group differences, but this difference was a function of the increased stature among the larger participants (P < 0.001). Ordinary least-squares regression models and multi-level regression models showed positive associations between the number of pedometer and activity monitor counts recorded by the three groups of participants during all activities (all P < 0.001). The mean number of counts recorded for all participants during the fast walk was 127 counts per minute. In conclusion, the pedometers provided an accurate assessment of adolescent physical activity, and a conservative estimate of 8000 pedometer counts in 60 min is equivalent to 60 min of moderate to vigorous physical activity.  相似文献

A brief overview of the Bibliographic Access and Control System developed by the Washington University School of Medicine Library is presented. Because the system has been described in two previous reports, this paper focuses on its relationship to other automated programs (i.e., PHILSOM and OCTANET), education of users, evaluation of the system, and outreach to the medical center. In operation for more than two years, BACS represents the computerization of much of the managerial and operational functions of the library, and marks the completion of stage 1 of the three stages of library evolution described in the AAMC report Academic Information in the Academic Health Sciences Center: Roles for the Library in Information Management.  相似文献

The online public access catalog consists essentially of a machine-readable database with network capabilities. Like other computer-based information systems, it may be continuously enhanced by the addition of new capabilities and databases. It may also become a gateway to other information networks. This paper reports the evolution of the Bibliographic Access and Control System (BACS) of Washington University in end-user searching, current awareness services, information management, and administrative functions. Ongoing research and development and the future of the online catalog are also discussed.  相似文献
