The Glass Ceiling on the Playing Fields Report Card III

The study evaluates, grades, scores and ranks 114 colleges in Division 1-A according to the number of female head coaches and assistant coaches of women’s teams and the number of head coaches and assistant coaches of men’s teams for the 2006–2007 academic/athletic year. The Report Card is the sum total of the college’s score on the four criteria. Central Florida University was rated highest for the third consecutive year.     

On the accuracy in high‐dimensional linear models and its application to genomic selection

Genomic selection is today a hot topic in genetics. It consists in predicting breeding values of selection candidates, using the large number of genetic markers now available owing to the recent progress in molecular biology. One of the most popular methods chosen by geneticists is ridge regression. We focus on some predictive aspects of ridge regression and present theoretical results regarding the accuracy criteria, that is, the correlation between predicted value and true value. We show the influence of singular values, the regularization parameter, and the projection of the signal on the space spanned by the rows of the design matrix. Asymptotic results in a high‐dimensional framework are given; in particular, we prove that the convergence to optimal accuracy highly depends on a weighted projection of the signal on each subspace. We discuss on how to improve the prediction. Last, illustrations on simulated and real data are proposed.     

Standby Mothering: Temporalities,Affects, and the Politics of Mobile Intergenerational Care

ABSTRACT

In this paper, I showcase how left-behind mothers in the Philippines use digital communication technologies in delivering care to their overseas adult children in Melbourne, Australia. As part of a broader research project on transnational family life, the findings were drawn upon in-depth interviews, visual methods, a simple participant observation, and field notes taking and analysis. The study deployed a mediated mobilities lens, paying close attention to the different forces that shape the provision of intergenerational care through mobile device use. Building upon a critical analysis of the digitalization of intergenerational relationships in a transnational context, I coin the term ‘standby mothering.’ This conception encapsulates the femininized, ubiquitous, networked, and ambivalent intergenerational care practices that are experienced and negotiated by distant mothers. On the one hand, mobile device use enables left-behind mothers to deliver emotional and practical caregiving. On the other hand, everyday temporal conditions and technological barriers impede the provision of intergenerational care. Communicative constraints are constantly managed through various tactics, ensuring the sustenance of transnational relationships. By interrogating the contradictory outcomes of transnational caregiving, I underscore the politics of mediated mobilities in a digital society. Here, the mobilization of gendered, networked, and differential care practices is influenced by uneven structural and even socio-technological dimensions. Ultimately, this paper elucidates a critical stance on re-examining the provision of informal, gendered, and networked care practices.     

Working mothers,injury and embodied care work

In this article, we examine how mothers respond when injury interrupts maternal care, using the lens of embodied care, which we conceptualize as a form of ‘body work’. We draw on findings from a qualitative research project with two organizations in Australia that help people with injuries to return to work, examining the experiences of workers who are also mothers of dependent children. Mothers' inability to care for children during periods of injury was a significant concern for our interviewees; constraints on physical labour and physical affection were particularly troubling, indicating the importance of embodied maternal caregiving to maternal roles. Yet, while these mothers inhabited the spheres of paid work and unpaid care work simultaneously, service providers did not consider embodied care work or its relevance to injured women's ongoing needs for support. While our findings reflect the experiences of injured women, they also suggest the need for a materialist analysis of the ways that both paid work and care activities are deeply enmeshed in and through the bodies of those doing the work. Employers and service organizations still fail to recognize maternal ‘body work’, and this may be typical of social attitudes more widely.     

Development of Multimodal Processing in Infancy

A number of studies have investigated infants' abilities to extract and discriminate number from multimodal events. These results have been mixed for several possible reasons, including aspects of the experimental design that provide perceptual cues that are unrelated to number, and are known to influence looking preferences. This experiment used a preferential looking paradigm to investigate whether 6‐ to 9‐month‐old infants can extract the amodal property of number from an arbitrarily related multimodal event sequence when nonnumerical confounds are removed. Results demonstrate that female infants discriminate number from a multimodal presentation by 6 months, whereas males do so by 8 months. Further, the study underscores the importance of controlling for low‐level perceptual cues in looking time experiments aimed at examining infants' cognitive abilities.     

Computation of the Generalized F Distribution

Exact expressions for the cumulative distribution function of a random variable of the form ( α ₁ X ₁+ α ₂ X ₂)/ Y are given where X ₁, X ₂ and Y are independent chi-squared random variables. The expressions are applied to the detection of joint outliers and Hotelling's mis-specified T ² distribution.     

Who Are the Alumni Donors? Giving by Two Generations of Alumni from Selective Colleges

Using data on former students of fourteen private colleges and universities, this paper examines patterns of alumni giving. The data are taken from the College and Beyond survey, which covers individuals who entered the institutions in the fall of 1951, 1976, and 1989. Contributions by these former students to these colleges and universities tend to be quite concentrated, with half of all donations being given by the most generous 1 percent of the sample. A higher level of contribution is associated with higher income, with having participated in extracurricular activities in college, with having had a mentor in college, and with the degree of satisfaction in one's undergraduate experience. The projected donations for the most generous of these alumni over the course of a lifetime are quite high, with totals for the 1951 cohort exceeding those from the 1976 cohort.
