Based on material collected in Barbados in 1964, this paper examines knowledge and use of birth control in terms of three types of family union-married, common law, and visiting. Analysis of knowledge of birth control is dealt with for the sample at large, for educational attainment, and for the average number of methods known by each woman. The relative importance of the different methods known is also treated by family type and education.The extent to which women in the sample make use of birth control is discussed from four aspects. First, the growing use of the different methods among younger-age cohorts is made evident from tabulations of methods-last-used. Second, information on the agencies and individuals recommending the use of different contraceptives emphasizes the degree to which the partner's influence is responsible for resort to birth control. Third, the proportions of users in religious groups show that religion is not a barrier to the use of any method. Fourth, the material is treated from the standpoint of age cohorts, since there is, in many cases, a vagueness as to the age at which use began, although women are able to identify the inter-pregnancy period when use began. 相似文献

Abstract This paper presents summary statistics of immigration into the West Indies, under indenture or government sponsorship, during the period 1834-1918. The sources reveal a few discrepancies, but are sufficiently consistent to permit the construction of a series for each of the ethnic groups introduced. Most of the problems involved in constructing these series centre around the fact that a variety of sources have to be utilised. Immigration figures of East Indians, Portuguese, Chinese, Europeans and others into the several West Indian colonies have been prepared for each calendar year or season, but to conserve space are presented here in summary form. In the case of African immigration it is possible to give their country of origin. The only group of immigrants who were involved in return movements of any consequence are the East Indians. 相似文献

Youth suicide is a leading cause of mortality. Greater still is the prevalence of suicidal behavior and ideation. In this study with 813 secondary school students, we explored youth engagement in structured extracurricular activities as a possible protective factor for suicidal ideation. Personally meaningful youth engagement significantly moderated the relationships between depressive symptoms, risk behaviors, self‐esteem, and social support in the prediction of suicidal ideation. Specifically, the more meaning found in engagement, the less likely youth were to report suicidal thoughts in spite of risk factors. Acknowledging limitations, a focus on engaging youth in well‐selected activities of interest might represent a nonstigmatizing approach to universal prevention. Further research into the mechanisms of such an approach is warranted. 相似文献

This article presents a historical reprise of 40 years of policy interest in ethnic minority businesses in the UK. It contrasts the pronouncements of policymakers with the reality of ethnic minority entrepreneurship. Such an exercise is surprisingly rare given the activism of policymakers in this arena and growing scholarly interest in this field. Our historical overview is informed by a novel research method that plots references to ethnic minority entrepreneurship in the British Houses of Parliament. Though the UK has been the site of some interesting policy experiments on ethnic minority entrepreneurship, their impact has been slight when set against the context of broader political-economic change. 相似文献

A central concern over global value chains (GVCs) is whether the integration of national firms into GVCs exacerbates income inequality within countries. However, despite decades of research, the distributional consequences of GVCs remain unclear in the empirical literature. Drawing on panel data from 96 countries between 1980 and 2013, we examine the effects of GVC integration on market income inequality and whether national labour regulations moderate these effects. We find integration increases inequality in the global North and South. More importantly, we find labour regulations amplify the inequality effects of integration in Southern countries by expanding the size of the informal sector while suppressing these effects in Northern countries by promoting unionization. This suggests institutional power from national labour regulations may enhance the bargaining power of labour in the North through increasing collective resources while disempowering labour in the South through reinforcing labour market segmentation between formal and informal sectors. 相似文献

Late talkers are a heterogeneous group of children who experience delayed language development in the absence of other known causes. Late talkers show delays in expressive phonological development, but less is known about their receptive phonological development. In the current study, U.S. monolingual English-speaking typical talkers (TTs) (n = 23, mean age = 26.27 months, 57% male; 78.3% White) and late talkers (n = 22, mean age = 24.57 months, 59% male, 72.7% White) completed a Looking-While-Listening task to assess their sensitivity to mispronunciations. Results revealed that late talkers and TTs looked to the referent of a word for a shorter duration when it was mispronounced than when it was correctly pronounced, suggesting they were sensitive to mispronunciations. However, there were no significant differences between the two groups in their sensitivity to mispronunciations. 相似文献
