Abstract The family is the foundation of our society. By learning about family life in other countries, we learn about our own lives and we realize that we all belong to one big family—the family of mankind. … [Studying families of the world] could help us to get closer to people in distant countries and support the knowledge that “we are one.” — Liv Ullmann, UNICEF Goodwill Ambassador 相似文献

Little is known about people's willingness to engage in sex without protection from unwanted pregnancy. This study surveyed 1,497 women and men at 75 clinics and physician offices across California after their reproductive health care visits in late 2007 and early 2008. When asked if they would have sex without contraception, 30% said definitively that yes, they would have unprotected sex, and 20% indicated they would “sometimes” or “maybe” engage in unprotected sex. In multivariate models, compared to non-Latino White respondents, Latinos who responded to the survey in English were 52% more likely and African Americans were 75% more likely to report willingness to have unprotected intercourse. Wanting a child within the next three years was associated with increased willingness to have unprotected sex. Age, gender, parity, and relationship status were not significant in multivariate models. A considerable proportion of women and men may be willing to have unprotected sex, even with access to subsidized contraceptive services and even when recently counseled about birth control. The dominant behavioral models of contraceptive use need to acknowledge the widespread likelihood of occasional unprotected sex, even among people motivated to usually use contraceptives. Findings underscore the need to make contraceptive methods accessible, easy to use, and even pleasurable. 相似文献

Midlife Women Online: Evaluation of an Internet-Based Program to Prevent Unintended Pregnancy & STIs
Lynne H. G. Swartz Christy A. Sherman S. Marie Harvey Jean Blanchard Faith Vawter Jeff Gau 《Journal of women & aging》2013,25(4):342-359
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

This article examines nonresponse in a large government survey,the American Time Use Survey (ATUS), which interviews personsin households previously interviewed in the Current PopulationSurvey. The response rate for the ATUS has been below 60 percentfor the first two years of its existence, raising questionsabout whether the results can be generalized to the target population.The article begins with an analysis of the types of nonresponseencountered in the ATUS. Noncontact accounts for roughly 60percent of ATUS nonresponse, with refusals accounting for roughly40 percent. We find little support for the hypothesis that busypeople are less likely to respond to the ATUS but find considerablesupport for the hypothesis that people who are weakly integratedinto their communities are less likely to respond, mostly becausethey are less likely to be contacted. When we compare aggregateestimates of time use calculated using the ATUS base weightswithout any adjustment for nonresponse, estimates calculatedusing the ATUS final weights with a nonresponse adjustment,and estimates calculated using weights that incorporate ourown nonresponse adjustment based on a propensity model, we findsome modest differences, but the three sets of estimates arebroadly similar. The article ends with suggestions for furtherresearch and analysis. 相似文献

This study examines whether mothers' or adolescents' expectations concerning “storm and stress” behaviors at adolescence predict subsequent real or perceived adolescent behavior and attributes during the early years of adolescence. The study used a short‐term longitudinal design. Participants were 6th‐ and 7th‐grade adolescents and their mothers (N=270 families). Data were collected via telephone interviews and questionnaires at 2 time points approximately 1 year apart. Results indicated that adolescents' expectations for risk‐taking/rebelliousness and for alienation and mothers' expectations for risk‐taking/rebelliousness predicted increases in corresponding adolescent‐reported outcomes over the 1‐year period. Results are most consistent with the possibility of perceptual biases with respect to storm and stress behaviors, but could indicate the existence of self‐fulfilling prophecies, particularly for risk‐taking/rebelliousness. 相似文献

This study examined how leaders create the impetus for creativity at work. One hundred ninety-three employees occupying a variety of jobs in Israeli organizations completed surveys at two points in time to assess their perceptions of the quality of their relationship with their leader (LMX), their level of energy, and their creative work involvement. SEM and regression analyses showed that LMX was positively related to employees' feelings of energy, which in turn were related to a high level of involvement in creative work. Factors that leaders should take into consideration in promoting followers' creative behaviors are discussed. 相似文献

Since the first properly randomized control trial of streptomycin for pulmonary tuberculosis in the late 1940s, society has made great advances in combating bacterial infections and in developing vaccines to prevent such infections. One constant challenge that anti‐bacterial clinical development must grapple with is to determine the potential benefit of newer agents over existing agents, in an era when anti‐bacterial resistance is a constantly shifting target. By contrast, the development of anti‐fungal agents went into high gear only in the late 1980s and early 1990s in an effort to manage fungal infections in cancer patients receiving chemotherapy, especially in patients with haematologic malignancies, bone marrow transplantation, or lymphoma. The pursuit of anti‐fungal agents intensified with the AIDS epidemic. The evaluation of anti‐fungal agents often faces complications brought on by competing risks in situations where the underlying infections are associated with a high chance of mortality or severe morbidity. In this paper, we use four case studies to illustrate some of the challenges and opportunities in developing anti‐bacterial and anti‐fungal agents. The illustrations touch on not only statistical issues, but also issues related to the availability of new anti‐bacterials in the future. Some suggestions on how statisticians could take advantage of the opportunities and answer to the challenges are also included. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

The construction of estimating equations by martingale methods is generalized to yield estimators with explicit expressions for the parameters of the birth-and-death and the general epidemic processes when only partial observations are available. (For the birth-and-death process the death process is observed but the number of births is observed only at the end and for the general epidemic process only the removal process is observed.) For large populations, the use of the martingale central limit theorem yields asymptotic confidence regions for the parameters. Explicit expressions are derived for estimators of the variances of the large sample distributions. The range of validity and usefulness of the new estimators is determined by simulation. 相似文献

AbstractThe mutiny that took place in Singapore in February 1915 is usually dismissed as a footnote in the history of empire. One reason why it is marginalized is because the mutiny does not conform to a politics that seeks the formation of an independent territorial nation-state as its inevitable conclusion. This article returns to that initial moment of insurgency to argue that the mutiny offers a unique window into the political imaginaries of British Indian soldiers, seen as military migrant workers. A close reading of soldiers’ letters against the Rowlatt Committee's Sedition Report suggests a politics of equality and emancipation uncontaminated by the desire for national liberation. Two kinds of insurgency thus become visible: international space as an unsettled zone of attraction and desire and a nascent political subjectivity that rejects the disciplines of imperial military labor. The primary causes of these transformations, I argue, are the insurgent effects of long-distance travel. 相似文献
