A New Air Quality Perception Scale for Global Assessment of Air Pollution Health Effects

Despite improvements in air quality in developed countries, air pollution remains a major public health issue. To fully assess the health impact, we must consider that air pollution exposure has both physical and psychological effects; this latter dimension, less documented, is more difficult to measure and subjective indicators constitute an appropriate alternative. In this context, this work presents the methodological development of a new scale to measure the perception of air quality, useful as an exposure or risk appraisal metric in public health contexts. On the basis of the responses from 2,522 subjects in eight French cities, psychometric methods are used to construct the scale from 22 items that assess risk perception (anxiety about health and quality of life) and the extent to which air pollution is a nuisance (sensorial perception and symptoms). The scale is robust, reproducible, and discriminates between subpopulations more susceptible to poor air pollution perception. The individual risk factors of poor air pollution perception are coherent with those findings in the risk perception literature. Perception of air pollution by the general public is a key issue in the development of comprehensive risk assessment studies as well as in air pollution risk management and policy. This study offers a useful new tool to measure such efforts and to help set priorities for air quality improvements in combination with air quality measurements.     

Child's Play? Children and Young People's Resistances to Domestic Violence and Abuse

Children and young people's (CYP) space to play can be constrained in families affected by domestic violence and abuse (DVA), potentially impacting their development. Play also has the potential to strengthen CYP's capacity to resist controlling and abusive dynamics in the family. Interviews were conducted with 107 CYP aged 8–18, and were analysed using interpretive interactionism. Three themes relevant to children's experiences of play were identified: Play and Coercive Control; Play Re‐makes the World and Play and Relationality. This article highlights the potential for play to enable children to retain a sense of relational connectedness and agency, despite violence and control; we argue for more opportunities for children to play away from the gaze of adults and advocate for more dedicated services for families who experience DVA.     

The politics of marital name change

Each year, millions of women face the decision whether or not to change their names after marriage. One study found that region, gender role traditionalism, career orientation, and educational attainment predicted name changes (Johnson and Scheuble, 1995). Another line of research discovered that women who changed their names were perceived as less ambitious and less competent, but more caring than women who did not change their name (Noordewier et al., 2010). Despite the prevalence and importance of this decision, we know very little about marital name change among political leaders. In this study, we take a preliminary look at marital name change in the political arena by focusing on name changing among women serving in the U.S. House and U.S. Senate. We find that half of female legislators keep their name after marriage, and that Democrats, racial minorities, legislators who come from political families, legislators who were married later in life, and legislators who were first elected to office at a younger age are more likely to keep their names.     

Parenting Supports for Early Vocabulary Development: Specific Effects of Sensitivity and Stimulation through Infancy

Growing recognition of disparities in early childhood language environments prompts examination of parent–child interactions, which support vocabulary. Research links parental sensitivity and cognitive stimulation to child language, but has not explicitly contrasted their effects, nor examined how effects may change over time. We examined maternal sensitivity and stimulation throughout infancy using two observational methods—ratings of parents’ interaction qualities and coding of discrete parenting behaviors—to assess the relative importance of these qualities to child vocabulary over time and determine whether mothers make related changes in response to children's development. Participants were 146 infants and mothers, assessed when infants were 14, 24, and 36 months. At 14 months, sensitivity had a stronger effect on vocabulary than did stimulation, but the effect of stimulation grew throughout toddlerhood. Mothers’ cognitive stimulation grew over time, whereas sensitivity remained stable. While discrete parenting behaviors changed with child age, there was no evidence of trade‐offs between sensitive and stimulating behaviors, and no evidence that sensitivity moderated the effect of stimulation on child vocabulary. Findings demonstrate specificity of timing in the link between parenting qualities and child vocabulary, which could inform early parent interventions, and support a reconceptualization of the nature and measurement of parental sensitivity.

“Best-Laid Plans”: Barriers to Meeting Marital Timing Desires Over the Life Course*

Abstract

Most youth desire to marry, and often around a certain age, but many individuals marry earlier or later than originally desired. Off-time marriage could have consequences for subsequent relationship stability and mental health. Whereas barriers to marriage goals in the short term have been studied extensively, predictors of meeting marital timing expectations over the life course are less well understood. This study examined possible barriers, including socioeconomic characteristics and family experiences, both background and formation, to meeting marital timing desires by age 40 using data from the National Longitudinal Survey of Youth 1979 cohort (NLSY79). Multinomial logistic regression revealed that greater education, religiousness, cohabitation, and premarital childbearing were associated with delayed or forgone marriage, but associations varied by gender and the age at which respondents stated their expectations.     

Utility values in health technology assessments: a statistician's perspective

This paper provides an introduction to utilities for statisticians working mainly in clinical research who have not had experience of health technology assessment work. Utility is the numeric valuation applied to a health state based on the preference of being in that state relative to perfect health. Utilities are often combined with survival data in health economic modelling to obtain quality‐adjusted life years. There are several methods available for deriving the preference weights and the health states to which they are applied, and combining them to estimate utilities, and the clinical statistician has valuable skills that can be applied in ensuring the robustness of the trial design, data collection and analyses to obtain and handle this data. In addition to raising awareness of the subject and providing source references, the paper outlines the concepts and approaches around utilities using examples, discusses some of the key issues, and proposes areas where statisticians can collaborate with health economic colleagues to improve the quality of this important element of health technology assessment.

作为黑人和牙买加后裔,霍尔并没有把自身的研究局限在单纯的种族问题和移民问题上,而是把对"新族性"的研究作为研究英国文化的切入点。霍尔认为,种族问题不是一个独立的问题,而是与整个文化状况相关联着的,"新族性"渗透于文化的各个角落,因此对"新族性"的研究其实是对英国文化的研究。     

Predictors of sexual risk-taking among new drug users

We studied predictors of HIV-related sexual risk-taking among individuals who initiated the use of heroin or methamphetamine during the past 5 years. Many studies have linked drug use to HIV risk and most research has been based on samples of users with long-established drug careers. We conducted face-to-face interviews with 153 adult new drug users in Atlanta, GA. Drug use was not a statistically significant predictor of sexual risk, but gender, age, race, homelessness status, childhood neglect, level of paranoia, and level of (dys)functionality in handling disagreements were associated with the frequency of sexual risk-taking. We discuss the need to incorporate new drug users in HIV/AIDS and other health-related prevention and intervention programs.
