民族地区发展可再生能源的现实分析及政策选择

可再生能源分布与民族地区存在高度一致性,民族地区发展可再生能源,具有重大的现实意义和战略意义.与传统化石能源开发利用对生态环境造成的破坏和压力相比,民族地区利用资源优势和政策机制发展可再生能源,不仅可以缓解能源不足的压力,改善能源结构,更能有效改善经济发展与自然、环境之间的矛盾或冲突,实现经济的可持续发展.     

苗族的"蒙毕"和"蒙朵"——兼论文化人类学视野下的族群关系

以我国西部散杂区苗族内部两个族群的互动关系为视角,从文化变迁角度进行田野观察,可以得出这样的结论:即族群是在民族其下可再细分的文化变量;族群研究有学院派与田野派之分,二派之间通过采取不同的研究思路,意在更清晰地解读国内人类学学术研究范式的发展趋势。     

权力视角下的民族分层——以当代以色列为例

国际政治现实主义理论大师汉斯·摩根索指出:"由于人口多少是国家权力强弱的一个因素,由于一个国家的权力总是与他国的权力相关,争夺权力的各国之间的相对人口、尤其是人口增长的相对速度,便值得认真对待了."摩根索除了强调人口数量对一个国家权力的影响之外,还指出人口质量(民族性格、民族士气等)也是影响一个国家权力的重要因素.     

Was there compression of disability for older Americans from 1992 to 2003?

Medical advances and the growth of the elderly population have focused interest on trends in the health of the elderly. Three theories have been advanced to describe these trends: compression of morbidity, expansion of morbidity, and dynamic equilibrium. We applied multistate life table methods to the Medicare Current Beneficiary Survey to estimate active and disabled life expectancy from 1992 to 2003, defining disability as having difficulty with instrumental activities of daily living or activities of daily living. We found increases in active life expectancy past age 65 and decreases in life expectancy with severe disability. These trends are consistent with elements of both the theory of compression of morbidity and the theory of dynamic equilibrium.     

Using age and spatial flow structures in the indirect estimation of migration streams

This article outlines a formal model-based approach for inferring interregional age-specific migration streams in settings where such data are incomplete, inadequate, or unavailable. The estimation approach relies heavily on log-linear models, using them to impose some of the regularities exhibited by past age and spatial structures or to combine and borrow information drawn from other sources. The approach is illustrated using data from the 1990 and 2000 U.S. and Mexico censuses.     

As low birth weight babies grow,can well-educated parents buffer this adverse factor? A research note

This research note combines two national Taiwanese data sets to investigate the relationships among low birth weight (LBW) babies, their parents' educational levels, and their future academic outcomes. We find that LBW is negatively correlated with the probability of such children attending college at age 18; however, when both parents are college or high school graduates, such negative effects may be partially offset. We also show that discrimination against daughters occurs, but only for daughters who were LBW babies. Moreover high parental education can buffer the LBW shock only among moderately LBW children (as compared with very LBW children) and full-term LBW children (as compared with preterm LBW children).     

Race,military service,and marital timing: Evidence from the NLSY-79

I use data from the 1979 National Longitudinal Study of Youth to examine the relationship between military service and marital timing for white men and black men during the 1980s. I use information about active-duty and reserve-duty service as well as veteran status to implement strong controls for selectivity. I find that active-duty military service increases the probability of first marriage for both whites and blacks. In part, this relationship is due to positive selectivity into the military and, for whites, to greater income and economic stability. Above and beyond the effects of selectivity, income, and economic stability, the effect of active-duty military service is particularly strong for black men.     

The demography of disability and the effects of immigrant history: Older Asians in the United States

Using data from the 2000 U.S. census, we compare the older Asian population with U.S.-born, non-Hispanic whites with respect to three indicators of disability. Insofar as any Asian "advantage" in health vis-a-vis whites exists among the population aged 65 and over, our evidence suggests that it occurs primarily among the U.S.-born segments of this population. We also investigate how differences in disability levels among Asian immigrant groups are influenced by country of birth and by the combined effects of duration of residence in the United States and life cycle stage at entry. These results highlight the diversity of the older Asian population with respect to the ways in which immigration and origin history are linked to disability outcomes. We conclude that in later life, immigrant status confers few disability advantages among the Asian population in the United States.     

Strength of attachment: Survey coverage of people with tenuous ties to residences

This article draws on evidence from an exploratory survey of living situations to assess the validity of assumptions about residence and to offer methodological innovations to improve coverage of people with tenuous attachment to households. These innovations include more inclusive probes and questions used to compile the roster of household residents; a review of the places a person stayed the previous few months; and a Residential Attachment scale that measures strength of attachment to households. This scale shows that it takes more probing to list tenuously attached people than most surveys do, suggesting that tenuously attached people are likely to be omitted from the typical survey roster. The Residential Attachment scale is correlated with social and economic participation in households, suggesting that participation is fairly high even among those with tenuous or no residential attachment.     

Child support and father-child contact: Testing reciprocal pathways

I use three waves of panel data to examine the relationship between child support payments and fathers' contact with their nonmarital children. I disaggregate support into fathers' formal and informal payments and incorporate cross-lagged effects models to identify the direction of causality between payments and contact. After including the behavior from the prior wave (lagged term) and a rich set of family characteristics, I find a marginally significant effect of paying formally at Time 1 on the likelihood of contact at Time 2 but no effect of contact at Time 1 on formal payments at Time 2. In the first examination of the relationship between informal support and father-child contact, I find a strong, positive reciprocal relationship between the likelihood and frequency of father-child contact and the likelihood and amount of informal support, with slightly stronger and more consistent effects of contact on payments than of payments on contact.
