Abstract

Smoking cessation behaviors of college students using a university health service were examined. Forty successful and 32 unsuccessful quitters were interviewed through an open-ended questionnaire. Elements important in successful, self-initiated cessation were sought. Results demonstrated many similarities between the groups. Differences seemed related to techniques used to remain abstinent from cigarette smoking, expectations of ease or difficulties in quitting, and the influence of a boyfriend/girlfriend. These differences should be studied in a larger sample. Questions raised for further study include: examining the influence of the health service and physician; identifying differences in attitudes toward cessation between quitters and recidivists; and evaluating what use smokers make of the knowledge gained through previous cessation attempts.

“Postprandial Glucose and Insulin Responses to Meals Containing Different Carbohydrates in Normal and Diabetic Subjects,” John P. Bantle, et al. To examine whether the form of dietary carbohydrate influences glucose and insulin responses, we studied the glucose and insulin responses to five meals–-each containing a different form of carbohydrate but all with nearly identical amounts of total carbohydrate, protein, and fat–-in 10 healthy subjects, 12 patients with Type I diabetes, and 10 patients with Type II diabetes. The test carbohydrates were glucose, fructose, sucrose, potato starch, and wheat starch. In all three groups, the meal containing sucrose as the test carbohydrate did not produce significantly greater peak increments in the plasma concentration of glucose or greater increments in the area under the plasma glucose-response curves than did meals containing potato, wheat, or glucose as test carbohydrates. Urinary excretion of glucose in patients with diabetes was not significantly greater after the sucrose meal. The meal containing fructose as the test carbohydrate produced the smallest increments in plasma glucose levels, but the differences were not always statistically significant. In healthy subjects and patients with Type II diabetes, peak serum concentrations of insulin were not significantly different in response to the five test carbohydrates.

Our data do not support the view that dietary sucrose, when consumed as part of a meal, aggravates postprandial hyperglycemia. (New England Journal of Medicine 1983;309:7–12.)  相似文献

Changes in the environment in which university research is conducted, in conjunction with the development of new research technologies such as biotechnology, are contributing to the proliferation and diversification of university‐industry relationships. This paper describes and documents university‐industry relationships in five categories: research contracts, technology transfer activities, consultancies, employment, and gifts. Special emphasis is given to biotechnology research relations. Conflicts that may arise from these relations are discussed and studies evaluating the potential impacts of university‐industry relationships are summarized. While wide‐spread abuse has not been reported, subtle changes in university research may be occurring. Using the University of Tennessee as a case study, the paper ends with a discussion of the difficulties of establishing guidelines and procedures to prevent and settle conflicts of interest that might result from university‐industry relationships.  相似文献

Youth in out‐of‐home care have elevated risks for adverse events and detrimental circumstances possibly affecting their development. Responses from 311 students in out‐of‐home care (OHC) were compared with peers living in birth parent care (BPC) and in single birth parent care (sBPC) in a regional school survey, directed to students in compulsory school eighth year and upper secondary school second year. Results indicate OHC students to experience less satisfaction with friends, leisure time, and families. They state less trust in support from friends and families but a more similar level to teachers, counsellors or nurses. OHC students also express being more exposed to abusive experiences online and perceive less sense of security at home and in school. We conclude that welfare institutions need to recognize the components in building trust and safety for students in OHC and that school and other professional institutions have an important role in serve resilience and promote well‐being for children in OHC.  相似文献

This paper, written jointly by tutors and students, discusses an enquiry-based approach to learning and assessing law as part of social work qualifying training in England. It is argued that social work law is an area of learning particularly suited to an approach in which enquiry and analysis skills are promoted through practical problem solving. The paper considers the theoretical rationale for this approach and identifies how this conceptual frame informs the learning and assessment structure. It identifies how students present evidence for assessment of their skill and knowledge development, through both written and verbal submission, and considers the learning outcomes achieved. The paper concludes with an evaluation of the approach as an example of knowledge and skill development through problem solving and reflection.  相似文献

Data from individual semistructured interviews with 90 young heterosexual couples were analyzed to identify strategies that men and women at risk of HIV/STDs would use to influence their partners to use condoms for the purpose of disease prevention. In addition, we explored whether participants thought influencing strategies would differ for pregnancy prevention. Content analysis of the interview data indicated that participants would use the following verbal strategies: persuading/suggesting, commanding/asserting, and threatening to withhold sex. Several participants, particularly those who had recently used condoms with their partners, reported that they would also use non‐verbal strategies involving condoms themselves (e.g., putting a condom on, buying or getting condoms, or presenting a condom to their partner). Many participants believed that they would use a different strategy for pregnancy prevention because it would be easier to convince a partner to use condoms for that purpose.  相似文献

Abstract

This article offers guidelines for learning and teaching structural equation modeling (SEM). The essential ingredients of an introductory course are presented on the basis of the authors' experience teaching SEM over the past two years. Also discussed are successful and unsuccessful methods of instruction, a practical way to organize the course, and a means to integrate this material into doctoral social work curricula. Teaching SEM can be a practical and worthwhile way to ensure that the profession will have well-trained researchers.  相似文献

An analysis of data from the 2000 Demographic and Health Survey shows that little use is made of antenatal and delivery-care services in rural Haiti. After adjusting for individual-level factors, poor road conditions significantly reduce the likelihood of timely receipt of antenatal care and of four or more antenatal care visits, while the availability of a health centre within 5 kilometres significantly increases the odds of each outcome. The odds of being attended at delivery by trained medical personnel and of institutional delivery are significantly reduced by mountainous terrain and distance from the nearest hospital, and are increased if a health worker providing antenatal care is present in the neighbourhood. Neighbourhood poverty reduces the likelihood of safe delivery care. The findings suggest that improving the use made of maternal healthcare services would require, among other things, improvement of the availability of services and road conditions, and the reduction of poverty.  相似文献

Background: Midlife women are an underserved population in the areas of unintended pregnancy and STI prevention yet remain at risk for both health conditions. Methods: A randomized controlled trial of an Internet-based multimedia program to reduce risk of unintended pregnancy and STIs among midlife women was conducted with 164 women ages 40–55 years of age. Results: Women in the treatment condition compared to the control condition reported significant gains in attitudes, self-efficacy, and behavioral intentions at posttest. Conclusion: Interventions specifically targeted to midlife women can impact constructs known to reduce risk. Implications for future research and intervention development are presented.  相似文献

Abstract

Universal services focus on prevention and providing the support to parents that will help them meet the challenges of parenthood and deal with problems before they become entrenched. Many countries now have good universal services available for new families, and significant advances have been made in recent years to recognize the importance of the early years in the optimal development of the child. This article is based on a qualitative study of transition to parenthood. The study explored the experience of 25 first-time mothers in socioeconomically diverse circumstances in New Zealand. Eleven partners of these women also participated. Mothers were interviewed three times, first in late pregnancy, then 3 and 12?months after giving birth. Partners were interviewed once, mid-way through the baby’s first year. The article focuses on how participants experienced service support. It illustrates some of the diverse needs of new parents, and explains ways in which prevention services might become more responsive to parents’ expressed needs. The authors offer a case for stronger interplay between universal services and informal systems of support, and the development of a new generation of universal services that act as enablers of natural support hubs for new families within their own communities.  相似文献
