Changes in Young Children’s Family Structures and Child Care Arrangements

Family structure change can disrupt the settings of children’s daily lives. Most scholarship focuses on disruption in the home environment. Moving beyond the home, this study explores the association between changes in family structure and changes in several dimensions of early child care. With longitudinal data from the NICHD Study of Early Child Care and Youth Development (n = 1,298), first-difference models reveal that family structure transitions are associated with changes in the type and quantity of early care as well as the number of care arrangements used, especially during the latter part of infancy. Given prior evidence linking these child care dimensions to behavioral and cognitive outcomes, these results suggest a policy-relevant mechanism by which family change may create inequalities among children.     

Practitioners as Rule Using Analysts: A Further Development of Process Knowledge in Social Work

Correspondence to Professor Michael Sheppard, Department of Social Policy and Social Work, University of Plymouth, Drake Circus, Plymouth PL4 8AA, UK. E-mail M.Sheppard{at}plymouth.ac.uk Summary A new paradigm of ‘process knowledge’ has emergedin recent years, distinct from the dominant ‘product knowledge’paradigm in social work. While the latter refers to existentknowledge, which may be applied, the former refers to the developmentof knowledge about the ‘methodology of practice decisionmaking’, focusing on the processes by which judgementsare made. At its heart is the emerging idea of a reflexivityfor practice, but studies have been, until recently, theoretical.A very small number of empirical studies have begun to identifysome key elements of process knowledge. These have developeda range of concepts relating to critical appraisal, hypothesisdevelopment and hypothesis testing which characterize socialwork process knowledge. These include, for example, focusedattention, querying information, causal inferences, partialcase, procedural, and speculative hypotheses. A process of quasitriangulation is characteristic of social work practice methodology,together with a combination of inductive and deductive thinking.This paper seeks to develop our understanding by focusing onhow social workers develop and appraise hypotheses, and in particularhow the substantive content of hypotheses emerges (these enablesocial workers to make sense of, define, and respond to, situations).To understand this, the notion of rules is used, and socialworkers emerge as analysts employing three types of rules: substantive,application, and practice rules. A significant link betweenprocess knowledge and the content of product knowledge is identifiedin the form of technical language. The concept of ‘probabilisticcausation’ is identified as a key epistemological dimensionin the conduct of rigorous practice.     

Complicating the Coming Out Narrative: Becoming Oneself in a Heterosexist and Cissexist World

Traditional stage models of LGBTQ identity development have conceptualized coming out as a linear process from “closeted” to “out” that all queer/trans individuals must follow if they are to be considered healthy and well adjusted. These stage models have been critiqued for their rigidity and absence of a dynamic understanding of the coming out process. In this article we explore the findings from a qualitative photovoice study with 15 LGBTQ youths in a small urban center in Ontario that supports these critiques. We explore the efficacy of the photovoice technique in investigating questions of sexual and gender identity. This article identifies some contextual factors that are important in understanding coming out as a social (rather than internal) process; it also identifies some of the ways in which these youths’ experiences challenge normative understandings of the “good, out queer.”     

Effects of habitat fragment size and isolation on the density and genetics of urban red-backed salamanders (Plethodon cinereus)

Urban expansion is creating environmental stressors through land use change, habitat fragmentation, and habitat loss. These stressors, along with a host of others, are driving precipitous declines in vertebrate taxa around the world. Amphibians, often requiring a narrow range of environmental conditions, can be especially susceptible to the stressors of environmental change. Despite habitat loss and degradation, some amphibian species continue to persist in altered urban landscapes. The red-backed salamander (Plethodon cinereus) is one such- species and in this study, we assess how habitat patch size affects population density and genetic diversity of salamander populations in and around an urban center in Ohio, United States. Further, we examined patterns of genetic differentiation and landscape connectivity to understand gene flow between populations and tested for historic demographic bottleneck effects. Populations were sampled from 9 urban forest patches ranging in size from less than 1 ha to approximately 250 ha. There was no apparent effect of contiguous habitat patch size on salamander density nor genetic diversity, but we did observe significant genetic differentiation between 97% of pairwise population comparisons. The differentiation observed was not a result of overland distance or effective distance due to landscape resistance. There was evidence of historic bottlenecks at every site. These results suggest that density is driven by within-patch heterogeneity and that genetic diversity is affected by drivers other than patch size or contemporary population density. Our study demonstrates that red-backed salamanders can persist in wooded, urban parks, but that genetic diversity remains susceptible to demographic changes.

     

Cold-related injuries in a cohort of homeless adults

People experiencing homelessness have an increased risk of cold-related injuries. This study determined the rate of emergency department (ED) visits for cold-related injuries among homeless adults and low-income controls in Toronto, Canada. Homeless individuals were recruited at shelters and meal programs. Age- and sex-matched controls living in low-income neighborhoods were selected. ED utilization was ascertained over 4-years of follow-up (2005–9) using administrative databases. A total of 16 ED visits for cold-related injuries were observed among 587 homeless men and 296 homeless women. The rate of ED visits was 6.7 (95% CI, 4.2–12.4) per 1000 person-years of observation among homeless men and 0.9 (95% CI, 0.03–5.6) among homeless women. ED visit rates were significantly higher among homeless men compared to low-income men (P?<?0.001) and significantly higher among homeless men compared to homeless women (P?=?0.03). Targeted public health interventions are needed to reduce the risk of cold-related injuries among people experiencing homelessness.     

A transactional model of infant still‐face response and maternal behavior during the first year

The present study takes a transactional approach to extend understanding of temporal relations between parenting behaviors and infant response to the face‐to‐face still‐face, a widely used method assessing infants’ affective and behavioral response to a violation of social expectations. A low‐income, urban sample of 180 mothers and infants participated when infants were 4 and 6 months old. Directional relations between infants’ still‐face response (i.e., change in affect and gaze from interaction to still face) and three parenting dimensions were examined using cross‐lagged structural equation models. Infant still‐face response predicted later parenting behavior, while the reverse association was not significant. Specifically, infants with a greater reduction in positive affect from interaction to still face had parents with more positive parenting and less negative parenting behaviors 2 months later, controlling for prior parenting and concurrent infant behavior. Furthermore, infants who increased gaze to mother from interaction to still face had mothers who used more mental state talk 2 months later. Findings underscore the importance of examining transactional relations between infant and parent behaviors, and in particular highlight the influence of infants on parents. Acknowledging these infant‐effects is critical to the development and implementation of interventions targeting parent‐infant interactions.     

Modelling locational access to markets for pluriactivity: a study in the Grampian region of Scotland

This paper investigates the role of location in determining the presence of on- and off-farm pluriactivity. Gravity models are developed to define degrees of access to markets from farm locations, and farm household survey data from the Grampian Region of Scotland are used to test the ability of the models to explain the observed location of pluriactivity. Proximity to markets is shown to be an important factor for both tourist and non-tourist on-farm diversification, and is reflected in the location of farms with on-farm non-agricultural activities. However, there is no evidence of a relationship between access to labour market opportunities and the presence of off-farm employment at the sub-regional scale. Personal preferences concerning work location and household responsibilities may be more important in determining the presence of off-farm work than proximity to labour market opportunities. Possible refinements to the technique and policy implications are discussed.
