Too hot to handle: African Caribbean pupils and students as toxic consumers and commodities in the educational market

Secondary sources are used in this paper to highlight how African Caribbean pupils and students – the Black British-born descendants of post-war Caribbean migrants – are victims of symbolic violence, because they are denied the educational capital needed to improve their social status. Since African Caribbean children entered the 1960s British educational sector, their learning has been perceived as problematic by the State. Although assimilation, integration and multicultural education policies were implemented to supposedly address the ‘problem’ of educating Black children, subsequent government reports identified racism as a significant barrier in their education. I argue here that the contemporary marketisation of education makes it increasingly difficult to distinguish between racism and competition, as causal factors of ethnic differences in educational attainment. Moreover, due to increasing private sector intervention and decreasing mediation by the State, racism is now hidden within the vicissitudes of the educational market. School exclusions and discriminatory practices in universities are viewed in this paper as major barriers to the economic success and future social mobility of Black Caribbean pupils and students. I conclude by suggesting that marketisation policies can be appropriated to ameliorate racism in education, but only if the political will to do so exists.     

Between a ROC and a hard place: Teaching prevalence plots to understand real world biomarker performance in the clinic

The Receiver Operating Characteristic (ROC) curve and the Area Under the Curve (AUC) of the ROC curve are widely used in discovery to compare the performance of diagnostic and prognostic assays. The ROC curve has the advantage that it is independent of disease prevalence. However, in this note, we remind scientists and clinicians that the performance of an assay upon translation to the clinic is critically dependent upon that very same prevalence. Without an understanding of prevalence in the test population, even robust bioassays with excellent ROC characteristics may perform poorly in the clinic. While the exact prevalence in the target population is not always known, simple plots of candidate assay performance as a function of prevalence rate give a better understanding of the likely real‐world performance and a greater understanding of the likely impact of variation in that prevalence on translation to the clinic.     

Explaining the Early Development and Health of Teen Mothers’ Children1

The transmission of social disadvantage from teenage mothers to their children is well established, but when and why do these disparities emerge in the early life course? Using nationally representative data from the Early Childhood Longitudinal Study‐Birth Cohort, this study investigated the relationship between teen childbearing and children’s cognition, behavior, and health from infancy through preschool. Developmental disparities between teenage mothers’ children and others were largely nonexistent at nine months but accumulated with age. Having a teenage mother predicted compromised development across several domains by age four and a half. Our conceptual model expected preexisting disadvantage, ongoing resource disadvantage, and compromised parenting quality to explain the association between teen childbearing and child outcomes. Preexisting social disadvantage accounted for much of this relationship. Financial, social, and material resources in the child’s household partially or fully explained each of the remaining significant relationships between teenage childbearing and child outcomes. Parenting quality explained a smaller proportion of these relationships than did resources, and these factors’ influences were largely independent. Because children of teenage mothers with a modest set of resources were not predicted to have compromised development, resources provided in early childhood may have the potential to reduce developmental disparities for teenage mothers’ children.     

Separating the Signal From the Noise: Evidence for Deceleration in Old-Age Death Rates

Widespread population aging has made it critical to understand death rates at old ages. However, studying mortality at old ages is challenging because the data are sparse: numbers of survivors and deaths get smaller and smaller with age. I show how to address this challenge by using principled model selection techniques to empirically evaluate theoretical mortality models. I test nine models of old-age death rates by fitting them to 360 high-quality data sets on cohort mortality after age 80. Models that allow for the possibility of decelerating death rates tend to fit better than models that assume exponentially increasing death rates. No single model is capable of universally explaining observed old-age mortality patterns, but the log-quadratic model most consistently predicts well. Patterns of model fit differ by country and sex. I discuss possible mechanisms, including sample size, period effects, and regional or cultural factors that may be important keys to understanding patterns of old-age mortality. I introduce mortfit, a freely available R package that enables researchers to extend the analysis to other models, age ranges, and data sources.     

In Search of Modifiable Risk and Protective Factors for Teen Dating Violence

The present research explores the additive and interactive effects of anger or hostility (A/H), acceptance of violence (AoV), and constructive conflict resolution strategies (CRS) on the perpetration of physical and sexual teen dating violence (TDV). Adolescents completed surveys assessing physical and sexual TDV perpetration, A/H, AoV, and positive CRS. While the findings require replication with longitudinal data, the results suggest that developing interventions to modify AoV and A/H may have the potential to prevent instances of TDV perpetration among both boys and girls. The results for CRS were mixed and necessitate further exploration. These cross‐sectional data provide insight into potentially fruitful areas of exploration for the development and tailoring of prevention strategies for teens at risk for physical and sexual TDV perpetration.     

明代方志出版中的财务问题

明代地方志出版中的财务问题可以根据五百多种明代府、州、县方志来考察。地方志比 其他书籍更有可能包含生产成本的信息,因为监督地方志编纂的官员们需要核算费用。编纂出版一部 地方志需要购买原材料和生产设备,需要支付编纂人员和工匠的工资、工人的伙食费、给协助编纂或撰 写序言者馈赠的礼品费用,以及诸如运输和储存费用等杂项支出。对这些条目繁多的花费情况的考察,不论是对中国地方志的研究,还是对普遍意义上的书史研究,都是很有意义的。     

Sex(ualities) and Symbolic Interaction

What goes on sexually has to be placed in a context of meaning. This might seem a very simple and obvious idea. And yet this is what makes it so important: most people still cannot see sexuality in this way. We continue to think of our sexualities as remaining firmly locked in the chains of biology. Whereas for humans surely the biological is really the least interesting aspect of our sexuality. So, whilst there remain huge armies of sexologists studying the biological in its various guises, the radical importance of the social still fails to find its proper place in the study of the sexual. —Ken Plummer, “Memoriam for Bill Simon” (2001)     

CEO Duality,Agency Costs,and Internal Capital Allocation Efficiency

This study examines the impact of CEO duality on firms’ internal capital allocation efficiency. We observe that when the CEO is also chair of the board, diversified firms make inefficient investments, as they allocate more capital to business segments with relatively low growth opportunities over segments with high growth opportunities. The adverse impact of CEO duality on investment efficiency prevails only among firms that face high agency problems, as captured by high free cash flows, staggered board structure and low board independence. Depending on the severity of the agency problem, CEO duality is associated with a decrease in industry‐adjusted investment in high‐growth segments of 1% to 2.1% over the following year, relative to that in low‐growth segments. However, CEOs’ equity‐based compensation curbs the negative effect of CEO duality on internal capital allocation efficiency. Overall, the findings of this study offer strong support for the agency theory and postulate the internal capital allocation policy as an important channel through which CEO duality lowers firm value in diversified firms.
