清末民初“英雌”及其相关概念族群的生成及其意义

清末民初，女权观念东渐和民族自强要求的一个极为可观的思想成果，便是对社会性剐女性英雄指认的阐扬，而其中的一个重要衡量参数就是有关女性英雄指认概念的大量出现和运用。准此，本论文对“英雌”及其相关概念族群的生成和意义进行了梳理和探讨。     

Race Differences in Sexual Behavior and Their Demographic Implications

Differences between blacks and whites in sexual behavior posited in Rushton's theory of r-K race differences were examined in the United States in an analysis of the annual surveys of the National Opinion Research Center for 1990–1996. This data set was analysed for black-white differences in numbers of sexual partners during the last 5 years and for frequency of sexual intercourse. The general pattern of the results was for blacks to report more sexual partners than whites and for black males to report greater frequency of sexual intercourse, consistent with Rushton's theory. This result has implications for the control of the AIDS epidemic and for the demographic transition among blacks.

Child,Parent, and Situational Correlates of Familial Ethnic/Race Socialization

This study examines child, parent, and situational correlates of familial ethnic/race socialization using nationally representative data gathered as part of the Early Childhood Longitudinal Study, Kindergarten Class of 1998 – 1999 (ECLS‐K). The ECLS‐K sample (N = 18,950) includes White, Black, Hispanic, Asian, Native Hawaiian/Pacific Islander, American Indian, and multiracial kindergarteners, with survey data available at the child, parent/guardian, teacher, and school level. We find that child correlates such as race and gender, parent correlates such as education and warmth of parent‐child relationship, and situational correlates such as percent of minorities at the child’s school and cultural event participation influence how often family members discuss children’s ethnic/racial heritage with them. We advocate for continued research of contextualized family dynamics.     

基于平均余命的中国养老金个人账户缴费率研究

平均余命是影响个人账户缴费率的重要因素之一。在退休人口平均余命逐步延长的趋势下,现行缴费率下的个人账户养老金积累额不能满足退休人口平均余命期间的支付需求,不能保障基本生活需要。如果不能及时依据平均余命适当调整个人账户缴费率,退休人口将面临因长寿风险而陷入生活贫困的境遇。本文测算了平均余命提高条件下中国2000~2050年个人账户缴费率的上限值与下限值范围,分析了职工个人缴纳养老保险费的经济承受能力,并提出了若干建议。     

Institutionalizing Counter‐Memories of the U.S. Civil Rights Movement: The National Civil Rights Museum and an Application of the Interest‐Convergence Principle

During the post–Reconstruction era in the United States, white southerners marked the cultural landscape with monuments and memorials honoring the Confederate cause and its heroes. These racialized symbols enjoyed an undisputed claim to public squares and parks throughout the South. It was not until the late twentieth century that commemorations to the black freedom struggle were publicly supported. This analysis examines the institutionalization of counter‐memories of the civil rights movement in Memphis, Tennessee at the Lorraine Motel, the site of the assassination of Reverend Dr. Martin Luther King, Jr. The author draws on collective memory, cultural trauma, and social movements research as well as critical race theory to explain the creation of the National Civil Rights Museum. Using primary and secondary data sources the author examines how social memory agents, a changing political culture, and the passage of time mediated the cultural trauma of King's assassination and influenced the institutionalization of oppositional collective memories. Relying on Derrick Bell's interest‐convergence principle, the author concludes that the creation of this major memorial museum was a result of the convergence of white and black interests, specifically the economic and political interests of white elites and the cultural and political interests of black symbolic entrepreneurs.

Expanding Boundaries of Whiteness? A Look at the Marital Patterns of Part‐White Multiracial Groups

Using a boundary perspective (Alba and Nee 2003 ), I examine the marital behavior of three self‐identified multiracial groups: black/whites, American Indian/whites, Asian/whites. With a focus on marriage with whites, I assess whether the boundaries of whiteness are expanding to include these part‐white multiracial groups. Marrying whites at a large scale may signify that part‐white multiracial Americans are in the process of being accepted as “white.” At the same time, due to differences in the racial identity experiences of multiracial groups, marital patterns may differ by racial combination. Based on analysis of 2008–2012 American Community Survey data, I find that the majority of all three groups are married to whites, suggesting that most members in these groups are on the path to whiteness. On the other hand, multinomial logistic regression analysis demonstrates that American Indian/whites and Asian/whites are more likely than black/whites to have a white spouse, relative to spouses of another race/ethnicity. Moreover, separate regression analyses by multiracial group reveal gender differences in their likelihood of marrying whites for black/whites and Asian/whites. These results indicate racial stratification in the marriage market among part‐white multiracial Americans, with further stratification by gender for some groups.     

‘Keeping the story alive’: is ethnic and racial dilution inevitable for multiracial people and their children?

This paper explores how multiracial parents with White partners articulate narratives of ethnic and racial ‘dilution’ and cultural loss in relation to the socialization of their children. In our broader study of how multiracial parents raise their children, we found that parents commonly spoke of concerns around dilution and generational change in relation to four key themes: the loss of cultural knowledge and diminishing practices that connected parents and their children to a minority ancestry; the embodiment of White‐appearing children and the implications of this for family relationships; the use of biological or genetic discourses in relation to reduced blood quantum; and concerns amongst Black/White participants about whitening and the loss of racial consciousness. Parental understandings of dilution varied greatly; some expressed sadness at ‘inevitable’ loss; others were more philosophical about generational change; and others still proactively countered loss through strategies to connect their children to their minority heritages. We show that despite growing awareness of the social constructedness of race and an emergent cosmopolitanism among these parents, discourses of genetics, cultural lineage, and the ‘naturalness’ of race continue to hold sway amongst many multiracial parents.
