长期以来,一谈到控制人口,减小人口压力,人们似乎总认为那仅仅是计划生育部门的任务。其实不然,纵观人口发展历史,人口的增减,发展速度的高低,以及人口问题对社会影响的大小等等,无不与当时的文化教育水平、经济状况有着直接联系。本文  相似文献

This paper examines an institutionalized friendship among adolescent girls and young women in southern Africa. Lesotho's economy is based on migrant male labor which leaves the women dependent on male earnings or subsistence from the land, and also creates unstable marital relations. Young girls in the modern schools develop close relationships, called "mummy-baby," with slightly older girls. Sexual intimacy is an important aspect of these relationships. Mummy-baby relationships not only provide emotional support prior to marriage, but also a network of support for married and unmarried women in new towns or schools, either replacing or accompanying heterosexual bonds.  相似文献

Mediation and moderation are two theories for refining and understanding a causal relationship. Empirical investigation of mediators and moderators requires an integrated research design rather than the data analyses driven approach often seen in the literature. This paper described the conceptual foundation, research design, data analysis, as well as inferences involved in a mediation and/or moderation investigation in both experimental and non-experimental (i.e., correlational) contexts. The essential distinctions between the investigation of mediators and moderators were summarized and juxtaposed in an example of a causal relationship between test difficulty and test anxiety. In addition, the more elaborate models, moderated mediation and mediated moderation, the use of structural equation models, and the problems with model misspecification were discussed conceptually.

BackgroundMany pregnant women use complementary and alternative medicine. Although midwives are often supportive, how they communicate with women about the safe use of these therapies has received limited research attention.AimThe aim of this study was to explore how midwives interact with women regarding use of complementary and alternative medicine during pregnancy.MethodsWe utilised grounded theory methodology to collect and analyse data. Twenty-five midwives who worked in metropolitan hospitals situated in Melbourne, Australia, participated in the study. Data were collected from semi structured interviews and non-participant observations, over an 18-month period.FindingsHow midwives communicate about complementary and alternative medicine is closely associated with the meaning they construct around the woman's role in decisionmaking. Most aim to work in a manner consistent with the midwifery partnership model and share the responsibility for decisions regarding complementary and alternative medicine. However, although various therapies were commonly discussed, usually the pregnant woman initiated the dialogue. A number of contextual conditions such as the biomedical discourse, lack of knowledge, language barriers and workplace constraints, limited communication in some situations.ConclusionMidwives often interact with women interested in using CAM. Most value the woman's autonomy and aim to work in partnership. However, various contextual conditions restrain overt CAM communication in clinical practice.  相似文献

This paper seeks to examine how female subjectivities are privileged by Canadian human papillomavirus (HPV) vaccination discourse and, in turn, how homosexual male subjectivities are displaced. Employing a Critical Discourse Analysis approach, I analyze selected HPV vaccination (HPVV) promotional materials, and depict the discursive strategies which privilege and exclude gendered subjectivities. My critical analysis is influenced by feminist linguistic works that seek to uncover the discursive constructions around sexuality, gender and identity, and the discursive strategies used to communicate ideas about sexual health risks and responsible citizenship. In addition, I adopt feminist theories of knowledge and power to rethink the discursive representations of some bodies and subjectivities as normal, and Others as unintelligible within HPVV discourse in today's neoliberal time.  相似文献

A decision-making framework based on the models of personal decision making developed by psychologists and economists and a methodology based on axiomatic conjoint measurement are used to explore individuals' beliefs and values regarding contraceptive sterilization. Particular emphasis is given to demonstrating a. that there exist individual differences in beliefs and values, b. that there exist differences in beliefs and values between persons who choose sterilization—either tubal ligation or vasectomy—and persons who choose non-sterilization contraceptive methods when no more children are wanted, and c. that the effect of beliefs and values on the sterilization decision is an interactive one. The methodology used is compared to that typically used in studying fertility- and health-related behaviors.This research was supported by grants HD-10802 and HD-14403 from the National Institute of Child Health and Human Development. The technical assistance of Doreen Victor and the editorial suggestions of Sarah Gaskill, Alice Healy, and two anonymous reviewers are greatly appreciated.

This research uses data from waves I and IV of the National Longitudinal Study of Adolescent Health (Add Health, N = 9,631) to consider whether and how family instability in early or later childhood affects college enrollment and completion of a Bachelor’s degree by age 24. Explanatory factors include maternal selection into unstable unions, household resources available in adolescence, and adolescents’ academic achievement, behavior, and attitudes in high school. The association of later family instability with college enrollment and completion is largely explained by household resources in adolescence. The association of early family instability with college enrollment is partially explained by each set of factors, and its association with college completion, given enrollment, is explained by pre-existing maternal characteristics. The results demonstrate that early family instability has enduring consequences for eventual status attainment and that the mechanisms that connect family instability to educational outcomes vary by the timing of family structure change.  相似文献

The relationship between population and economy is regarded seriously by China and other countries. This problem can be analyzed and studied under 2 aspects: 1) the influence of economic development on changes in population, and 2) the influence of population increases on economic development. Under the 1st aspect, improved living conditions, hygiene, and health care generally result in lowered mortality rates. Improved economic conditions in China also increased the birthrate and at the same time increased birth control among the people; the increased birthrate was due to more marriages after liberation. In economically advanced countries, due to high expenses in raising children, people tend to limit family sizes to 2 children/family. Under the 2nd aspect, population increases place strains on the food supply and nutritional requirements, especially when increases are too rapid. They also demand more educational resources and influence quality of education. As there are currently 210 million students in China, the quality of education suffers, particularly at the college level, since most of Chinese manpower, physical and financial resources are spent on primary and secondary education. In terms of housing, transportation, health care, and natural resources, they are all intimately related to and influenced by increases in population. Consequently, the living standard would be difficult to raise if population increases are too rapid. Since 1971, population increases have been incorporated into 5-yearly and later yearly national economic plans in China. The large Chinese population is a major obstacle in raising the Chinese economic level, hence a well-planned population control program is essential.  相似文献

Despite attempts to expand social diversity, policing is still dominated by a white, masculine, heterosexual ethos. As a consequence, employment of lesbians and gay men as police officers may be especially threatening to members of this occupation. Within the context of potential hostility and homophobia, nontraditional officers must negotiate their contradictory presence on the police force. This paper investigates that negotiation. Using the Bem Sex Role Inventory and open-ended survey data from a sample of "out" and "closeted" gay and lesbian police officers, we ask how gays and lesbians manage their images as "good cops" in the face of gender norm violations associated with their sexual orientation. Our findings indicate that masculinity and femininity do not hold together in a cohesive, dichotomous manner for these officers. Instead, other characteristics that enhance policing are emphasized to support their occupational competence. These officers see themselves as "good cops." The gendered/sexualized character of their self-perceptions appears to matter less than the context of the job, more than for a comparison sample of heterosexual police officers. We conclude that although gay and lesbian officers see their sexuality as an occupational asset, they are also likely to work harder to prove themselves as crime fighters.  相似文献
