Newborn Infants' Preference for Attractive Faces: The Role of Internal and External Facial Features

Several previous experiments have found that newborn and young infants will spend more time looking at attractive faces when these are shown paired with faces judged by adults to be unattractive. Two experimental conditions are described with the aim of finding whether the “attractiveness effect” results from attention to internal or external facial features, or both. Pairs of attractive and less attractive faces (as judged by adults) were shown to newborn infants (mean age 2 days, 9 hours), where each pair had either identical internal features (and different external features) or identical external features (and different internal features). In the latter, but not the former, condition the infants looked longer at the attractive faces. These findings are clear evidence that newborn infants use information about internal facial features in making preferences based on attractiveness. It is suggested that when newborn (and older) infants are presented with facial stimuli, whether dynamic or static, they are able to attend both to internal and external facial features.     

Perspectives on American Kinship in the Later 1990s

This paper reviews the current status of kinship research in the United States and identifies factors that might account for the declining interest in the subject among family researchers. The analysis uses both structural and cultural factors to illustrate how they can determine the diversity in kinship functioning that ranges from those family systems where kinship relationships flourish and those where they play a small part in family life. The structural and demographic variables determine the numbers and availability of kin, whereas the cultural variables determine the norms that establish the motivation to sustain kinship bonds. To illustrate how these factors operate among subgroups in the United States, I analyze three types of kinship systems: the lineal emphasis in White families of the very old; the collateral emphasis in the families of their Black counterparts; and the egocentric emphasis of White suburban families that are undergoing marital change.     

Maternal Interactive Style Across Contexts: Relations to Emotional, Behavioral and Physiological Regulation During Toddlerhood

Sixty-five mothers and their 24-month-old toddlers were observed in a series of laboratory procedures designed to assess relations between maternal interactive style and emotional, behavioral and physiological regulation. Emotional regulation was assessed by examining the child's behaviors (aggression, distraction, object focus) when confronted by three emotion-eliciting tasks. Behavioral regulation was measured by examining children's ability to comply to maternal requests and to inhibit behavior during a delay task. Physiological regulation was derived from children's cardiac vagal tone responses to emotionally-arousing situations. Maternal interactive style was assessed by examining mothers' strategies for child behavior management (negative controlling, positive guidance) during three mother-child tasks. Maternal behavior was related to regulation in each of the three domains. Negative maternal behavior was related to poor physiological regulation, less adaptive emotion regulation, and noncompliant behavior. Positive maternal behavior was correlated with compliance, but not with any of the physiological or emotional measures. These findings are discussed in terms of the adaptive value of self-regulation in early development, and the importance of identifying the causal relations between maternal behavior and child regulation.

A hierarchical theory of occupational segregation and wage discrimination

Becker's model of discrimination is extended to the case where men exhibit distastes for working under female managers. The distribution of women in the resulting occupational hierarchy depends on the number of women in lower occupations, the wages of male workers in lower occupations, and male distastes for female management. Thus, there exists an occupational sorting function, related to wages, that determines the occupational distribution of women. We integrate this sorting function into a standard wage equation to derive a new decomposition of male-female wage differentials and apply it to a sample of insurance industry workers from the 1988 CPS.     

Risk Prediction for Prostate Cancer Recurrence Through Regularized Estimation with Simultaneous Adjustment for Nonlinear Clinical Effects

In biomedical studies, it is of substantial interest to develop risk prediction scores using high-dimensional data such as gene expression data for clinical endpoints that are subject to censoring. In the presence of well-established clinical risk factors, investigators often prefer a procedure that also adjusts for these clinical variables. While accelerated failure time (AFT) models are a useful tool for the analysis of censored outcome data, it assumes that covariate effects on the logarithm of time-to-event are linear, which is often unrealistic in practice. We propose to build risk prediction scores through regularized rank estimation in partly linear AFT models, where high-dimensional data such as gene expression data are modeled linearly and important clinical variables are modeled nonlinearly using penalized regression splines. We show through simulation studies that our model has better operating characteristics compared to several existing models. In particular, we show that there is a non-negligible effect on prediction as well as feature selection when nonlinear clinical effects are misspecified as linear. This work is motivated by a recent prostate cancer study, where investigators collected gene expression data along with established prognostic clinical variables and the primary endpoint is time to prostate cancer recurrence. We analyzed the prostate cancer data and evaluated prediction performance of several models based on the extended c statistic for censored data, showing that 1) the relationship between the clinical variable, prostate specific antigen, and the prostate cancer recurrence is likely nonlinear, i.e., the time to recurrence decreases as PSA increases and it starts to level off when PSA becomes greater than 11; 2) correct specification of this nonlinear effect improves performance in prediction and feature selection; and 3) addition of gene expression data does not seem to further improve the performance of the resultant risk prediction scores.     

A GIS Analysis of East Asian Care Gaps in Residential and Assisted Living Facilities in Vancouver,Canada

Residential care and assisted living services provide support to seniors who may not have the ability to live independently. However, East Asian residents often do not have sufficient access to culturally specific activities, which may result in psychosocial stress and isolation. This study presents a geographic analysis method to evaluate spatial distribution of culturally tailored senior care facilities in Metro Vancouver. We identify geographical disparities, indicating that many East Asian seniors have poor local access to a culturally tailored facility. We recommend the use of geographical analysis techniques to improve the analysis and planning for senior care in an increasingly diverse population.
