毛泽东农业基础地位思想及其当代价值探究

新中国成立后,毛泽东充分论证了农业发展对国家经济、政治、国防发展的重要作用,提出了＂农业是国民经济的基础＂的思想,这个思想对于当前我国农业发展仍有着重要的现实意义。农业在国民经济中的功能决定了农业始终是我国国民经济的基础。但是,我们对农业的重视不能仅仅停留在农业对国民经济贡献的认识上,更不能继续采取对农业进行索取的做法,而应把农业放在整个国民经济协调发展的全局和世界视野的高度上。     

Socio-demographic Differences in Self-reported Psychological Distress Among 25- to 64-Year-Old Finns

Background Mental health problems are a major public health issue worldwide. The aim of this study was to assess the relative importance of socio-demographic characteristics associated with different domains of psychological distress in Finland. Methods Data source was a nationwide survey “Health Behaviour and Health among the Finnish Adult Population” (AVTK), from years 2002 to 2003 (N = 5425; response rate 66%). Psychological distress was measured by self-reported questions of general mental health (MHI-5), depression, insomnia and stress. Socio-demographic factors included education, employment status, partnership and children living in the household. Main analyses were conducted by multivariate logistic regression. Results Education, employment and partnership were associated with most of the psychological distress outcomes. Respondents with a lower educational level had poor mental health in both genders but less insomnia and stress in men. Those with an intermediate education had the least stress in women. The unemployed and retired were at a higher risk for poor mental health and depression. Moreover, employment status was associated with insomnia and stress in men. Respondents not having a partner showed a higher risk of psychological distress according to all measures. Not having children living in the household was associated with insomnia in women and with less stress in men. Conclusions Socio-demographic factors, such as having a partner and employment status, are associated with several measures of psychological distress indicating the importance of social and economic factors to psychological well-being. The association of education and of having children living at home varies by the domain of psychological distress measure.     

Structural Pluralism and Life Expectancy in Less-Developed Countries: The Role of Women's Status

This study replicates a previous finding forthe U.S. counties that showed a strongassociation, net of controls between``structural pluralism' and lower mortality. ``Structural pluralism' refers to a community'scapacity for political competition, and is acore element of ``democracy.' Pluralism hasthis effect because it facilitates theacquisition of appropriate medical facilitiesand because it tends to optimize the biologicalfunctioning of the residents. Working from amajor component of pluralism, minorityparticipation, this hypothesis is tested byshowing that women's status in less developedcountries improves life expectancy net ofcontrols. A path analysis demonstrates thatthe structural dimensions work through healthorganization as an intervening variable, andthe future testing of biological optimizationis outlined. Location in Africa south of theSahara is a partially unexplained controlvariable that has a powerful negative impact. Interpreting women's status as a component ofpluralism explains why it predicts increasedlife expectancy for all citizens, not justwomen. It is a global dimension that affectsall the members of a community.     

Social Background Differences in Early Family Behavior

Social background has historically been recognized as a major factor influencing family behavior, though recent work has largely emphasized racial/ethnic influences. Here we use 1994 – 1995 and 2001 – 2002 Add Health data to examine the cohabitation, first marriage, and first birth experience of young women. In a multistate life table context, hypothetical cohorts specified in terms of race and mother’s education are followed, from age 11 to age 24, as they move through 6 family‐related statuses. The results indicate that, for both Black and White women, a higher level of maternal education is generally associated with less cohabitation, less marriage, fewer first births, and a higher percentage of women who experience none of those transitions before age 24. Racial and social background differences are conceptually and empirically distinct. Because mother’s education is associated with substantially different trajectories of early family behavior for both Blacks and Whites, we argue that social background merits increased attention in research on contemporary American family patterns.     

婚姻状态对老年人死亡概率的影响研究--基于CLHLS队列数据的实证分析

文章基于 CLHLS 队列数据,运用统计分析及经验论证,解析出婚姻状态影响老年人死亡概率的作用机理,即在婚状态以其“保护效应”减小老年人患病的机率,进而减小其死亡概率;相反,不在婚状态的“损害效应”会增加老年人患病的机率,进而增加其死亡的概率。在所得结论基础上,为促进老年健康和应对养老挑战,针对老年人婚姻问题提出了相关政策建议。     

Conquering with capital: social,cultural, and economic capital’s role in combating socioeconomic disadvantage and contributing to educational attainment

While socioeconomic barriers to learning have been well-documented by education, sociology, and social policy scholars, further research is needed to understand how students with low-socioeconomic status excel in high-performing schools. The collection and analysis of 20 in-depth interviews with female college students from different racial and socioeconomic backgrounds provide rich insights into the stark differences between the educational practices of low and high-SES students. Building on Bourdieu’s conceptualization of how habitus and capital influence practices in the field of education exposes unique, strategic practices that low-SES students use to attain educational success within a system of reproduction and power. While entering a high-performing school is often perceived as a definitive step for accessing high-quality educational resources, my findings illustrate how it is actually an important intermediary step within a more complex process. Increasing educational opportunity and attainment for low-SES students requires improving their access to social, cultural, and economic capital through knowledgeable mentors who contribute to a habitus and portfolio of capital which enable practices to successfully navigate and challenge the educational system.     

Additive hazards regression of current status data with auxiliary covariates

This paper discusses the regression analysis of current status failure time data arising from the additive hazards model with auxiliary covariates. As often occurs in practice, it is impossible or impractical to measure the exact magnitude of covariates for all subjects in a study. To compensate the missing information, some auxiliary covariates are utilized instead. We propose two easy-to-implement procedures for estimation of regression parameters by making use of auxiliary information. The asymptotic properties of the resulting estimators are established and extensive numerical studies indicate that both procedures work well in practice.     

Do peer effects mediate the association between family socio‐economic status and educational achievement?

Differences in levels of academic achievement according to socio‐economic status (SES), and parental education in particular, have been a persistent feature of Australian education systems. Young people with highly educated parents are more likely than their peers with low‐educated parents to attain high levels of achievement at school. Students with low levels of achievement are less likely than their high achieving peers to complete Year 12 and are more likely to experience negative post‐school outcomes. The SES of the neighbourhood, and in particular, the school attended, has also been found to have an effect on levels of both academic achievement and attainment. For this paper, we conduct analyses of National Assessment Program – Literacy and Numeracy test scores for four cohorts of secondary school students attending government schools in the Australian Capital Territory to examine the associations between parental education, school attended and levels of educational achievement. Our findings show that students with university‐educated parents achieve at much higher levels than their peers with low‐educated parents and that attending a school with a higher proportion of students from educationally disadvantaged families has a negative effect on educational achievement.     

Labor Market Disparities Between African Americans and Afro Caribbeans: Reexamining the Role of Immigrant Selectivity

Black immigrants from the Caribbean have long attained greater labor market success than African Americans. The most recent studies show that Afro Caribbeans have earnings that are approximately 16% greater than African Americans and that Afro Caribbeans are as much as 21% more likely to be employed than African Americans. The most prominent explanation for greater Afro Caribbean success is that, because they have chosen to migrate, Afro Caribbeans are positively self‐selected on characteristics that are key for success in the U.S. labor market. Proponents of immigrant selectivity argue that migrants have greater levels of both hard and soft skills than nonmigrants. Using data from the National Survey of American Life—the first social survey to provide a nationally representative sample of both African Americans and Afro Caribbeans—this study finds that Afro Caribbeans have greater hard skills than African Americans but split the difference on two measures of soft skills: African Americans and Afro Caribbeans are matched on John Henryism, but African Americans have greater personal mastery than Afro Caribbeans. Contrary to expectations, controlling for differences in hard and soft skills does not provide for a meaningful reduction in labor market disparities between African Americans and Afro Caribbeans.     

Racial/Ethnic Patterns of Kindergarten School Enrollment in the United States

Enrollment into unequal schools at the start of formal education is an important mechanism for the reproduction of racial/ethnic educational inequalities. We examine whether there are racial/ethnic differences in school enrollment options at kindergarten, the start of schooling. We use nationally representative data from the Early Childhood Longitudinal Study‐Birth Cohort (ECLS‐B) to model whether parents seek information about their child's school before enrolling, whether parents move to a location so that a child can attend a certain school, or whether parents enroll their child in a school other than the assigned public school. Results indicate that enrollment patterns differ greatly across race/ethnicity. Whereas Black families are the most likely to seek information on a school's performance, White families are the most likely to use the elite option of choosing their residential location to access a particular school. These differences persist when controlling for socioeconomic status and sociogeographic location. Kindergarten enrollment patterns preserve the advantages of White families, perpetuating racial/ethnic disparities through multiple institutions and contributing to intergenerational processes of social stratification. Research should continue to examine specific educational consequences of housing inequities and residential segregation.
