What can we learn from twin studies? A comprehensive evaluation of the equal environments assumption

Twin studies are a major source of information about genetic effects on behavior, but they depend on a controversial assumption known as the equal environments assumption (EEA): that similarity in co-twins’ environments is not predictive of similarity in co-twin outcomes. Although evidence has largely supported the EEA, critics have claimed that environmental similarity has not been measured well, and most studies of the EEA have focused on outcomes related to health and psychology. This article addresses these limitations through (1) a reanalysis of data from the most cited study of the EEA, Loehlin and Nichols (1976), using better measures, and through (2) an analysis of nationally representative twin data from MIDUS using more comprehensive controls on a wider variety of outcomes than previous studies. Results support a middle ground position; it is likely that the EEA is not strictly valid for most outcomes, but the resulting bias is likely modest.

北亚突厥百年研究(1900-2000年)

突厥是生活在我国北方的一个游牧民族。其在公元六世纪中叶,兴起于今新疆东北部,势力扩大到漠北、漠南及中亚一带,衰于八世纪中叶。本文综述阿尔泰以东的突厥即传统上所说的东突厥的范围近百余年的研究。包括族源、族属、社会性质、社会经济、语言、文字、习俗、宗教、碑文、官号、与周边各族各国间的关系和其他方面的内容。通过这些研究,可以发现我国学者在百年来对突厥巨大成就,使国际学术同行了解我国学者在这一领域取得的成果,促进此方面的进一步研究。该文可能对方家一些著述有遗漏,或者评述失当之处,请予指教。     

Intergenerational class mobility in contemporary Britain: political concerns and empirical findings

In Britain in recent years social mobility has become a topic of central political concern, primarily as a result of the effort made by New Labour to make equality of opportunity rather than equality of condition a focus of policy. Questions of the level, pattern and trend of mobility thus bear directly on the relevance of New Labour's policy analysis, and in turn are likely be crucial to the evaluation of its performance in government. However, politically motivated discussion of social mobility often reveals an inadequate grasp of both empirical and analytical issues. We provide new evidence relevant to the assessment of social mobility - in particular, intergenerational class mobility - in contemporary Britain through cross-cohort analyses based on the NCDS and BCS datasets which we can relate to earlier cross-sectional analyses based on the GHS. We find that, contrary to what seems now widely supposed, there is no evidence that absolute mobility rates are falling; but, for men, the balance of upward and downward movement is becoming less favourable. This is overwhelmingly the result of class structural change. Relative mobility rates, for both men and women, remain essentially constant, although there are possible indications of a declining propensity for long-range mobility. We conclude that under present day structural conditions there can be no return to the generally rising rates of upward mobility that characterized the middle decades of the twentieth century - unless this is achieved through changing relative rates in the direction of greater equality or, that is, of greater fluidity. But this would then produce rising rates of downward mobility to exactly the same extent - an outcome apparently unappreciated by, and unlikely to be congenial to, politicians preoccupied with winning the electoral 'middle ground'.     

英国马克思主义美学在中国的译介与研究

目前,中国学术界对英国马克思主义美学著作的译介与研究存在着不均衡的局面,即译介正在走向繁荣,而研究却相对薄弱。本文认为,在英国马克思主义美学著作的译介和研究过程中还存在探讨不够深入、留有空白领域、忽视方法论的研究与转换等问题,今后应予以修正与完善。     

Towards an assessment for organizational participatory research health partnerships: A systematic mixed studies review with framework synthesis

Within the health sciences, organizational participatory research (OPR) is defined as a blend of research and action, in which academic researchers partner with health organization members. OPR is based on a sound partnership between all stakeholders to improve organizational practices. However, little research on the evaluation of OPR health partnership exists. This systematic mixed studies review sought to produce a new theoretical model that structures the evaluation of the OPR processes and related outcomes of OPR health partnerships. Six bibliographic databases were searched together with grey literature sources for OPR health partnership evaluation questionnaires. Six questionnaires were included, from which a pool of 95 OPR health partnership evaluation items were derived. The included questionnaires were appraised for the quality of their origin, development and measurement properties. A framework synthesis was performed using an existing OPR framework by organizing questionnaire items in a matrix using a hybrid thematic analysis. This led to our proposed Organizational Participatory Research Evaluation Model (OPREM) that includes three axes, Trust, Collective Learning and Sustainability (with specific dimensions) and 95 items. This model provides information to help stakeholders comprehensively structure the evaluation of their partnerships and subsequent improvement; thus, potentially helping to improve health organization practices.     

A critical approach to wage devaluation: The case of Spanish economic recovery

In line with the orientation of EU economic policy, the Spanish government has favoured a strategy of internal devaluation as a way of adjusting price levels within the currency union. The results of empirical studies indicate that the internal devaluation applied in Spain does not seem to have attained the desired goals in terms of reducing the relative prices of exports and consolidating a model of growth based on external demand. Indeed, the estimates drawn up show that tailwinds – the depreciation of the euro and the fall in risk premium as results of the measures taken by the ECB, greater economic activity by trading partners and the fall in the price of oil – exercised a decisive influence in the trends followed by the prices of exports and the balance of trade during the period of crisis management in Spain.     

Pussy grabs back: bestialized sexual politics and intersectional failure in protest posters for the 2017 women’s march

The women’s march on Washington on January 21 2017 and its more than 600 sister marches across the world was characterized by its distinctly feline theme. Most notable were the pink pussy hats and a multitude of signs that played on the historical association between women and cats to resist the crude remarks made by US presidential nominee Donald Trump who bragged of grabbing women “by the pussy.” This article explores this feline counterframing from a vegan feminist perspective. A content analysis was performed on photographs that were published in Why I March (2017) and uploaded to the Women’s March on Washington Archives Project, the Georgia State University Women’s Marches 2017 Collection, and Instagram in Spring 2017. Results illustrate the persistent role that animality plays in feminist politics, but they also point to a critical intersectional failure exhibited by an ultimately anthropocentric collective.
