Sex and Sexuality in China. Edited by Elaine Jeffreys

Survey data from samples of undergraduates at a small Southern university indicate significant increases in rates of premarital intercourse, significant decreases in average age at first experience, and significant increases in average number of partners between 1970 and 1981. Although attitudes toward premarital intercourse and behavior (i.e., reported coitus) were interrelated, this relationship was significantly stronger for women (V = .676) than for men (V = .325). Although differences between men and women still exist, these differences are much more evident in attitudes than in behavior. Women are still more conservative than men in their attitudes toward the kinds of relationships in which premarital coitus is personally acceptable. Some explanations for this continuing ideological difference are presented.     

What do child characteristics contribute to outcomes from care: A PRISMA review

This article presents the findings from a systematic review of the literature regarding factors related to positive placement outcomes. Children in care are particularly vulnerable to problems with their emotional and behavioural development. It is important to know which factors affect whether children will have a positive placement outcome or not. Previous research has aimed to examine this, and has found that certain child characteristics can affect placement outcome. Reviews have not reported their search strategy in line with PRISMA guidelines, nor have they always reported the source of the data. This review was particularly interested in which studies had contact with the children or carers themselves, as opposed to a reliance on administrative data. There appear to be child characteristics that affect placement outcome, but findings need to be interpreted with caution due to a high volume of results from administrative data. Future research should aim to conduct full assessments with children when they come into care.     

Psychosocial and Environmental Determinants of Eating Behaviors,Physical Activity,and Weight Change Among College Students: A Qualitative Analysis

Abstract

Objective: The goal of this study was to identify factors that college students perceived as contributing to healthy and unhealthy eating patterns, physical activity (PA) levels, and weight change. Participants: Forty-nine 18- to 22-year-old students at a midwestern university participated. Methods: Six focus groups (3 with each gender) were conducted, and data were analyzed using qualitative software to code and categorize themes and then reduce these to clusters according to commonly practiced methods of qualitative analysis. Results: Eating and PA behaviors appear to be determined by a complex interplay between motivations and self-regulatory skills as well as the unique social and physical environment comprising college life. Moreover, there appear to be gender differences in how these determinants impact behavior. Conclusions: Future research should examine these interactions in the college context in order to further our understanding of potential interventions or environmental modifications that support healthy eating and PA.

Mothers' Speech to Hearing‐Impaired Infants and Children With Cochlear Implants

This study investigated the effects of age, hearing loss, and cochlear implantation on mothers' speech to infants and children. We recorded normal‐hearing (NH) mothers speaking to their children as they typically would do at home and speaking to an adult experimenter. Nine infants (10–37 months) were hearing‐impaired and had used a cochlear implant (CI) for 3 to 18 months. Eighteen NH infants and children were matched either by chronological age (10–37 months) or hearing experience (3–18 months) to the CI children. Prosodic characteristics such as fundamental frequency, utterance duration, and pause duration were measured across utterances in the speech samples. The results revealed that mothers use a typical infant‐directed speech style when speaking to hearing‐impaired children with CIs. The results also suggested that NH mothers speak with more similar vocal styles to NH children and hearing‐impaired children with CIs when matched by hearing experience rather than chronological age. Thus, mothers are sensitive to hearing experience and linguistic abilities of their NH children as well as hearing‐impaired children with CIs.
