The census-enumerated American Indian population dispersed rapidly between 1930 and 1990. Changes in ethnic classification account for most of the change. In the 1980 count, 10 states with historically large Indian populations account for 53% of births of Indians between the ages of 10 and 80, compared with 72% of the first enumerations of the same cohorts. Migration further reduced the share of these states to 46% of Indian residents in these cohorts. Study of the dispersal of the Indian population should focus primarily on the new emergence of the expression of Indian identity, rather than on migration from former population centers.  相似文献

Fiji is peculiar in having within its population a component population of immigrant origin which has remained ethnically distinct from all other groups and which, in recent years, has become numerically predominant in the population. The other major component is the indigenous Fijian population and between them Fijians and Indians constituted more than 92% of the total population enumerated in the 1956 census. The Indian component is increasing more rapidly than is the Fijian and the factors contributing to these differential rates of increase have been analysed and are presented in this paper. The changes which have occurred over the last ten years in the patterns of mortality and fertility in each group are examined, and the likelihood of further changes are discussed in relation to the economic implications of the present age structure of the populations.  相似文献

This article examines discourses on race and sexuality in scientific literature during the late-nineteenth and early-twentieth centuries in context of U.S. settler colonialism. It uses a theoretical and methodological intersectional perspective to identify rhetorical strategies deployed in discursive representations salient to lesbian, gay, bisexual, transgender, Two-Spirit, and queer American Indians and Alaska Natives. These representations reflect a context of compounded colonization, a historical configuration of co-constituting discourses based on cultural and ideological assumptions that invidiously marked a social group with consequential, continued effects. Hence, language is a vector of power and a critical vehicle in the project of decolonization.  相似文献

The objectives in this statement are to characterize and explain the patterns of change in stratification and mobility in Egypt, over the last half century, by placing them within conceptual, explanatory, and historical contexts. First, literature relevant to the primary concepts of "class" and "status", is reviewed. Second, four institutions whose influence is fundamental in shaping these patterns are identified to form an explanatory context: family, polity, economy, and education. And third, an historical account is presented to demonstrate the interplay of these institutions and their consequences for stratification and mobility. For this, four periods are identified that are marked by change in the dominance of institutions and their corresponding influence on stratification and mobility. In addition to data available in relevant literature, this analysis utilizes primary data generated through a national probability household survey.  相似文献

This paper deals with the analysis of the misery index in a group of 55 African countries by using fractional integration or I(d) techniques. In doing so, we can measure the degree of persistence of the index in a more flexible way than with other methods that simply use integer degrees of differentiation (zero or one). Our results indicate a large degree of heterogeneity across the countries, with some showing short memory behaviour (d?=?0); others long memory mean reverting behaviour (0?<?d?<?1) and others indicating the presence of unit roots (d?=?1). Thus, shocks will have different effects depending on the country examined. Generally, we also find a positive relationship between the levels of persistence and income.

Background

American Samoan women are particularly at risk of obesity-related non-communicable disease (NCD), requiring efficacious interventions to protect their health and that of their infants. Prior studies have identified pregnancy as an ideal time for behavior change interventions related to NCD.

Aim

This study aimed to understand American Samoan women’s conceptions of health during pregnancy, their motivations for pregnancy behavior change, and the role of their family in both enabling and preventing these changes.

Methods

Eighteen women (2–19 weeks post-partum) completed semi-structured interviews that explored their experiences of pregnancy-related behavior change and social support. A thematic analysis identified prominent themes. A stages of change framework was used to describe the sample’s readiness for behavior change.

Findings

Participants expressed a Westernized conception of health during pregnancy that focused on eating a balanced diet and exercising regularly; behaviors that would usually be stigmatized outside of pregnancy. Many were in the contemplative/pre-contemplative stages of change, although some reported initiating healthful behaviors in pregnancy. Participants overwhelmingly described external motivations for adopting healthy behaviors, most notably the perceived benefit to their baby. During pregnancy, women reported protective treatment from their families as a result of communal ownership over the baby that is potentially limiting for women’s agency over their health.

Conclusions

This study confirmed pregnancy as an opportune moment for health behavior intervention, especially within the context of Samoan culture. Future efforts should capitalize on external motivations for behavior change but also encourage the development of internal motivators to sustain changes initiated in pregnancy post-partum.  相似文献

This study examines the time series behavior of infant mortality rates within a long memory approach with non-linear trends using data for 37 countries. The main results show significant differences both in the degree of integration and non-linearities among the analyzed series. Furthermore, non-linearities in the time trends are found in most of the cases, in contrast with the main assumption of linearity used in the literature. Finally, the results on the integration order of the series have important policy implications in many areas, such as on international convergence in mortality rates, on the income and infant mortality relationship, and, on whether health policy interventions will have transitory or permanent effects on infant mortality rates.  相似文献

Intergenerational mobility has remained stable over recent decades in the United States but varies sharply across the country. In this article, I document that areas with more prevalent slavery by the outbreak of the Civil War exhibit substantially less upward mobility today. I find a negative link between prior slavery and contemporary mobility within states, when controlling for a wide range of historical and contemporary factors including income and inequality, focusing on the historical slave states, using a variety of mobility measures, and when exploiting geographical differences in the suitability for cultivating cotton as an instrument for the prevalence of slavery. As a first step to disentangle the underlying channels of persistence, I examine whether any of the five broad factors highlighted by Chetty et al. (2014a) as the most important correlates of upward mobility—family structure, income inequality, school quality, segregation, and social capital—can account for the link between earlier slavery and current mobility. More fragile family structures in areas where slavery was more prevalent, as reflected in lower marriage rates and a larger share of children living in single-parent households, is seemingly the most relevant to understand why it still shapes the geography of opportunity in the United States.  相似文献

Demographic interest in population and environment has grown in recent decades. One of the most prominent research areas in this tradition addresses the impact of population on land use and land cover change. Building on this tradition, we examine the effects of household demographic composition on land use and land cover on small farms in two study areas in the Brazilian Amazon. Fixed effects regression models of used area and forested area show few consistent effects of changes in household demography on land use and land cover change. Effects are inconsistent with the household life cycle model that currently dominates the literature on household demographic effects in frontiers. Changes in the number of children and women, particularly young women, have the most significant effects on land use and land cover change. We conclude by arguing that households strategically access cash for investment in agriculture and that specific strategies are determined by economic and institutional context.

Measuring and explaining the change in life expectancies   总被引:11,自引:0,他引:11  
A set of new indices for interpreting change in life expectancies, as well as a technique for explaining change in life expectancies by change in mortality at each age group are presented in the paper. The indices, as well as the new technique for explaining the differences in life expectancies, have been tested and examples using United States life tables are presented. The technique for explaining life expectancy differentials can be used for analyzing change in mortality or mortality differentials by sex, ethnicity, region, or any other subpopulations. The technique can be applied to life expectancies at birth or temporary life expectancies between any desirable ages.  相似文献

Identity may be understood both as a life-story, either told or written as memoir or autobiography, and also as a practice such as producing or acting in gay pornographic film, but always within the context of social and historical change. Study of the memoirs of gay men who have been actors and/or producers of gay pornographic films across three generation cohorts provides an opportunity for understanding the interplay of social change and life circumstances in making gay identity. This perspective on identity is illustrated through the study of the memoirs of three men from different cohorts who have produced and acted in gay pornographic films: Wakefield Poole, born in 1936; Scott O'Hara, born in 1961; and Aaron Lawrence, born in 1971. Differences in style and content of both memoir and practice in gay pornographic films reflect changing social expectations regarding men who have sex with men following the emergence of the gay rights movement and the AIDS epidemic.  相似文献

It has been hypothesized that populations may experience an increase in their natural fertility during the early stages of modernization as a result of the relaxation of various fertility-inhibiting practices and customs prevalent in traditional societies. This article offers evidence of such an increase in natural fertility among Canadian Indians. The main underlying cause is found to be in the massive, almost abrupt, shift from prolonged breastfeeding to bottle feeding which took place prior to the onset of large-scale birth control practices among Canadian Indians.  相似文献

Within the extensive food insecurity literature, little work has been done regarding (a) the depth and severity of food insecurity and (b) the food insecurity of American Indians. This paper addresses both these topics with data from the 2001 to 2004 Core Food Security Module of the Current Population Survey. To measure food insecurity, three axiomatically derived measures of food insecurity are used. As expected, given the worse economic conditions facing American Indians, their food insecurity levels are generally higher than non-American Indians. However, the magnitude and significance of these differences differ depending on the choice of food insecurity measure.

Pockets of high fertility persisted in some areas of the American South through the Great Depression. Most other areas of the country adopted modem fertility patterns considerably earlier in the century; these “laggard” areas are clear exceptions to the national demographic revolution in family building. In this paper we attempt to identify the factors that account for the persistently high fertility in some southern regions. We use county-level data for 1940 to assess the utility of three theoretical models of fertility: structural, diffusion-innovation, and health. Differences by race are also considered, in view of the distinctly different histories of whites and African-Americans in the south. Our findings suggest that unicausal explanations for the persistence of high fertility are too simplistic; all three theoretical perspectives receive empirical support. Considerable similarity is observed in the findings for blacks and for whites. Yet important differences also emerge, especially the more powerful effects of structural variables on white fertility. We conclude that the evidence indicates the need for “diversity” in the study of demographic behavior. Not only should we examine a variety of causal mechanisms for demographic phenomena; we also should consider the varying utility of those mechanisms across different social groups.  相似文献
