Housing Conditions of Nuclear and Extended Households in the Miami-Fort Lauderdale Area

Arrivals of new immigrants into the south Florida area have put increased pressure on housing markets and fostered renewed efforts to provide more affordable housing. Many view household extension largely as a response to the lack of a sufficient amount of affordable housing. This paper examines the nature, proportion and housing condition of nuclear and extended households in the Miami-Fort Lauderdale area. The study also investigates how the incidence and housing situation of extended households has changed during the period from 1986 to 1990. This study illustrates that extended families in the Miami-Fort Lauderdale area are not uniformly worse off than nuclear families, given ethnicity and income level. While the area's housing problems require attention, some of that attention should be focused on removing institutional barriers to household extension and to providing broader housing choices for minority ethnic groups.     

Respiratory illness in Saskatoon infants: The impact of housing and neighbourhood characteristics

Respiratory illness is an important childhood illness and a significant cause of infant mortality. This study examined the relationship between neighbourhood level variables and rates of respiratory illness for children less than 2 years of age, born in Saskatoon between 1992 and 1994. Rates of respiratory illness, as measured by proportion of children hospitalized and frequency of hospitalization and ambulatory visits to physicians, were higher among infants living in socially disadvantaged neighbourhoods. Multivariate predictive models for rates of respiratory illness support the research hypothesis that housing characteristics, in the presence of other neighbourhood characteristics, have a significant impact on determining the rates of respiratory illness among Saskatoon children.     

The Equivalence of Neyman Optimum Allocation for Sampling and Equal Proportions for Apportioning the U.S. House of Representatives

We present a surprising though obvious result that seems to have been unnoticed until now. In particular, we demonstrate the equivalence of two well-known problems—the optimal allocation of the fixed overall sample size n among L strata under stratified random sampling and the optimal allocation of the H = 435 seats among the 50 states for apportionment of the U.S. House of Representatives following each decennial census. In spite of the strong similarity manifest in the statements of the two problems, they have not been linked and they have well-known but different solutions; one solution is not explicitly exact (Neyman allocation), and the other (equal proportions) is exact. We give explicit exact solutions for both and note that the solutions are equivalent. In fact, we conclude by showing that both problems are special cases of a general problem. The result is significant for stratified random sampling in that it explicitly shows how to minimize sampling error when estimating a total T_Y while keeping the final overall sample size fixed at n; this is usually not the case in practice with Neyman allocation where the resulting final overall sample size might be near n + L after rounding. An example reveals that controlled rounding with Neyman allocation does not always lead to the optimum allocation, that is, an allocation that minimizes variance.     

Open Access Mandates and Policies: The Basics

Abstract

Universities can afford to subscribe to only a small percentage of available scholarly journals. Consequently, researchers do not have access to all articles in journals pertinent to their fields of study. The Open Access (OA) movement began in response to wanting to find a solution to this “serials crisis” and the availability of the Internet to disseminate scholarly research in new and innovative ways to a larger, worldwide audience. OA mandates are policies adopted by research institutions, universities, or funders that require researchers to provide free, unrestricted access to their published research by publishing in OA journals, depositing their articles in an OA repository or both. This edition of “In Lay Terms” provides basic information about OA mandates and policies, gives an overview of university and funder OA mandates, discusses geographic differences in policies and compliance rates, and reviews United States federal funding agencies’ OA policies and Plan S.     

Impacts of child development accounts on parenting practices: evidence from a randomised statewide experiment

ABSTRACT

This study examines the impact of Child Development Accounts (CDAs) on parenting practices of mothers with young children in a statewide randomised experiment conducted in the United States. The experiment included 2704 primary caregivers of children born in Oklahoma during 2007: 1358 were randomly assigned to the treatment group and 1346 to the control group. Structural equation modelling suggests that the punitive-parenting score among treatment participants was .12 standard deviations smaller than that among control participants (p < . 05). Findings indicate that CDAs reduce punitive parenting, and may serve as an additional tool for positive parent–child interactions.     

Capability Traps Impeding Homeless Services: A Community-Based System Dynamics Evaluation

Continuums of Care (CoCs) are the primary coordinating bodies for homeless services in the United States. However, the complexities involved in delivering homeless services across interagency networks challenges coordination and system improvement. CoC governance, planning, and service provision have received little attention in academic literature, and thus, Continuums attempt to manage complex systems with little guidance. This evaluation applied community-based system dynamics with homeless consumers and service providers to (1) identify capability traps that impede services delivery and to (2) engage stakeholders in a structured system improvement process. Results revealed organizational structures for governance and planning that inhibit system outcomes. Insights led to policy and practice recommendations for the homeless system.     

Vulnerable Multiracial Families and Early Years Services: Concerns,Challenges and Opportunities

In Britain, very young mixed-parentage children are more likely to receive state care than any other children. However, despite a dramatic increase in the number of multiracial families, their experiences have received little research attention. This article reviews the research on the experiences of vulnerable and poor multiracial families. Three areas of concern emerge—the relationship between family structure, locality and racism, disadvantage and oppression; the impact on family life of structurally reinforced and culturally defined gender roles; and the strengths and limitations of current early years research and practice. Suggestions are made about ways in which early years professionals might develop their practice with young vulnerable multiracial families.
