Explicit Versus Implicit Family Decision-Making Strategies Among Mexican American Caregiving Adult Children

Changing U.S. demographics make it increasingly vital to investigate experiences of Latinos caring for aging parents, with specific emphasis on how these families, who often value family closeness, make decisions about caregiving. This study investigates relationships among use of implicit versus explicit decision-making strategies, generation since immigration, and orientation toward family. Findings suggest that those with more recent immigration to the United States were more likely than those who immigrated longer ago to describe family decision making about their parents' care as implicit. Those that were classified as using predominately implicit decision making were also found to be not significantly different from those classified as predominantly explicit with regard to their overall support of a collective orientation toward family. There were exceptions to this, however, regarding two specific aspects of orientation toward family: engagement in shared activities with family members and avoiding family conflict by making choices that are consistent with the family values. In both cases those categorized as implicit expressed stronger endorsement of these specific values. These findings suggest that the relationship between family decision-making strategies, generation since immigration, and orientation toward family is more complex than suggested previously in the literature. Implications for future research and practice are offered.     

How Parents and Teachers View Their School Communities

ABSTRACT

This study examines the perceptions of more than 11,000 parents and 1,500 teachers about their schools, themselves, and their relationships with each other within their school communities. It provides insights into the health of our public schools, their reservoirs of social capital, and the context they provide for student learning. The nature and strength of relationships within school communities is assayed through examination of parents' and teachers' perceptions about their roles, the roles of students, school–home communication, the common experience and climate of the school, and their face-to-face association with one another. Teachers' perceptions are compared with those of parents, and the perceptions of White, non-Hispanic, Black, non-Hispanic, and Hispanic parents are compared with each other.

中国区域人口素质变迁与经济增长研究

文章利用人口总数、人口出生率、平均受教育年限、教育基尼系数、卫生经费比、老年人口抚养比、第三产业就业人数比和城镇人口比等8个指标,选取32个省市自治区1997 -2010年数据,采用因子分析法构造人口综合素质指数,并运用道格拉斯生产函数模型分总体和地区进行混合面板数据回归,发现人口素质对经济增长影响显著,且东、中、西部和东北地区人口素质差异明显,对经济增长的贡献率也相差悬殊,表明西部地区正在由劳动密集型发展阶段向资本拉动型阶段转变,中部和东北地区由资本拉动型阶段向人口素质推动型阶段转变,东部地区属于人口素质推动经济不断优化阶段.最后,还针对区域发展差异提出了相应的举措和建议.

The Level and Age Pattern of Mortality in Bandafassi (Eastern Senegal): Results From a Small-Scale and Intensive Multi-Round Survey

The data collected in the Bandafassi demographic study in Eastern Senegal, a small-scale intensive and experimental follow-up survey of a population of about 7,000 in 1983, were analysed to derive an estimated life table. The use of multi-round surveys, combined with anthropological methods to estimate ages and collect genealogies, has resulted in unusually reliable data. Taking into account the uncertainty of the estimates due to the small size of the population, mortality was high, with life-expectancy at birth close to 31 years; a pattern of infant and child mortality close to that observed in other rural areas of Senegal, with a very high level or mortality between ages six months and three years; a seasonal pattern in child mortality with two high-risk periods, the rainy season and the end of the dry season; an adult mortality pattern similar to that described in model life tables for developed countries; no significant difference by sex or ethnic group. The Bandafassi population study and a few similar studies suggest that one possible way to improve demographic estimates in countries where vital registration systems are defective would be to set up a sample of population laboratories where intensive methods of data collection would continue for extended periods.     

Marital dissolution among the 1958 British birth cohort: The role of cohabitation

This paper investigates the effect of previous cohabitation on marital stability among the 1958 British birth cohort. Prospective data from the National Child Development Study are used to investigate the way in which family background factors and early lifecourse experiences, including cohabitation, affect the risk of first marriage dissolution by age 33. Discrete time logistic regression hazards models are used to analyse the risk of separation in the first eight years of marriage. Many socio-economic and family background factors are found to act through more intermediate determinants, such as age at marriage and the timing of childbearing, to affect the risk of separation. Previous cohabitation with another partner and premarital cohabitation are both associated with higher rates of marital breakdown. The effect of premarital cohabitation is attenuated but remains significant once the characteristics of cohabitors are controlled, and cannot be explained by the longer time spent in a partnership.     

Demographic transition in sub-Saharan Africa: How big will the economic dividend be?

In mid-demographic-transition, many Asian countries enjoyed a large demographic ‘dividend’: extra economic growth owing to falling dependant/workforce ratios, or slower natural increase, or both. We estimate the dividend, 1985–2025, in sub-Saharan Africa and its populous countries. Dependency and natural increase peaked around 1985, 20 years after Asia. The UN projects an acceleration of the subsequent slow falls but disregards slowish declines in young-age mortality and thus, we argue, overestimates future fertility decline. Even if one accepts their projection, arithmetical and econometric evidence suggests an annual, if not total, dividend well below Asia's. The dividend arises more from falling dependency than reduced natural increase, and could be increased by accelerating the fertility decline (e.g., by reducing young-age mortality) or by employing a larger workforce productively. Any dividend from transition apart, low saving in much of Africa (unlike Asia) means that, given likely natural increase, current consumption per person is unsustainable because it depletes capital per person.     

Counter-Examples about Lower- and Upper-Bounded Population Growth

ABSTRACT

For a unimodal growth function f having its maximum at a critical state x _c , the interval bounding the population size asymptotically is usually presented as being equal to [f ^○2(x _c ), f(x _c )]. This interval however does not represent the maximum range within which the population size can vary, even asymptotically. The actual invariant interval containing the population size is equal to: [min(x*, f ^○2(x _c )), f(x _c )], where x* denotes the non-zero fixed point, assumed to be unique, of the iteration of f.     

Intrinsically Dynamic Multistate Models

Multistate life table models, which follow persons through more than one living state, have found increasing use in demographic analyses. Multistate stable populations, however, are infrequently used because the constant rate assumption is quite strong and such populations can take centuries to approach stability. Dynamic models, that is models where the rates can change over time, are examined to derive a new solution for the size and composition of a multistate population in terms of the sequence of underlying population projection matrices (PPMs). Constraints on the subordinate eigenvalues and the subordinate eigenvectors of the time-varying PPMs produce a model population that grows according to the dominant eigenvalues of each time-specific PPM and has a state composition that depends only on the most recent PPM. The two living state model is examined in detail, relationships between the PPM elements and the size and composition of the model are explored, and two illustrative applications of the model are presented.
