Inequality of opportunity in the United Kingdom, 1991–2008

We investigate the extent to which the tax-and-transfer system of the United Kingdom equalizes opportunities for income attainment among citizens. Within the framework of Roemer’s theory of Equality of Opportunity, and using individual data from the British Household Panel Survey from 1991 to 2008, we calculate the tax rates necessary to equalize opportunities for different circumstances. We provide a ranking of these circumstances by the degree to which they influence income attainment. Although pre-fisc equality of opportunity increases over time, the tax rate necessary to equalize opportunities remains higher than the observed tax rate. Only under a relatively high labour supply elasticity the observed UK tax rate fares well in equalizing opportunities for income attainment.     

Risk, Statistical Inference, and the Law of Evidence: The Use of Epidemiological Data in Toxic Tort Cases

Toxic torts are product liability cases dealing with alleged injuries due to chemical or biological hazards such as radiation, thalidomide, or Agent Orange. Toxic tort cases typically rely more heavily than other product liability cases on indirect or statistical proof of injury. There have been numerous theoretical analyses of statistical proof of injury in toxic tort cases. However, there have been only a handful of actual legal decisions regarding the use of such statistical evidence, and most of those decisions have been inconclusive. Recently, a major case from the Fifth Circuit, involving allegations that Benedectin (a morning sickness drug) caused birth defects, was decided entirely on the basis of statistical inference. This paper examines both the conceptual basis of that decision, and also the relationships among statistical inference, scientific evidence, and the rules of product liability in general.     

Racial intermarriage pairings

Most studies of racial intermarriage rely on the prevalence of intermarriage to measure the strength of group boundaries, without scrutinizing the nature of intermarriage pairings. Examination of intermarried couples' characteristics reveals (1) that intermarriages and endogamous marriages follow different patterns, and (2) that intermarriage pairings for some groups reflect a generalized racial status hierarchy. According to evidence from the 1990 U.S. Census PUMS, patterns in blacks' and Mexican Americans' marriages with whites suggest that a generalized racial status hierarchy disadvantages members of these minority groups. For marriages between Japanese Americans and whites, however, crossing the group boundary does not affect couples' characteristics.     

Stakeholders’ partnership approach to infrastructure provision and management in developing world cities: lessons from the Sustainable Ibadan project

In recent decades unprecedented urbanization has constituted a huge challenge to urban infrastructure development and management in most developing countries. Meanwhile, the appropriateness of conventional urban planning approaches to the improvement of urban environmental conditions in the face of deteriorating urban environment have often been questioned. It became inevitable to search for new approaches particularly in the context of low-income urban communities. International organizations such as the United Nations Development Programme (UNDP) and the United Nations Centre for Human Settlements (UNCHS) have subsequently initiated strategies to evolve a participatory approach to the development and management of the urban environment. One of such strategies is the Sustainable City Programme (SCP) which aims to provide municipal authorities and city stakeholders in the public, private and community sectors with an enhanced capacity for environmental planning and management. The programme is being implemented in several cities in parts of the developing world, including Ibadan – the Sustainable Ibadan Project (SIP) – in Nigeria. This paper examines the partnership approach to urban environmental infrastructure improvement, development and management as represented by the SIP. The relevance of the participatory partnership approach of the SIP for cities in parts of developing regions is examined. The paper implicitly stresses that bottom-up participatory stakeholder partnership is a strategy capable of enlisting the financial, material resources and expertise of various sectors of the urban community towards the improvement of urban environmental infrastructure. The paper presents preliminary findings of a study. Although traditional appraisal techniques were not employed, nonetheless, the paper presents a discussion of the processes and dynamics of the SIP on the basis of which some useful lessons may be drawn.     

Substance use and its relationship to family functioning and self-image in adolescents

This study examined associations between substance use, family functioning, and self-image among four ethnic adolescent groups. Three thousand three hundred and fifteen 8th and 9th grade students were recruited from 10 schools in Los Angeles County. Participants completed a paper-and-pencil survey regarding their alcohol and marijuana use, along with their perceived family functioning and self-image and other demographic variables. Ordinal logistic regression was performed to examine associations. Results indicated that both family functioning and self-image were significantly associated with alcohol and marijuana use. Those who scored lower on family functioning and self-image were at increased risk for substance use. Furthermore, students who scored low in both family functioning and self-image were about twice as likely to report using alcohol.     

Risk factors and services for child maltreatment among infants and young children

Objectives

Child maltreatment (CM) causes injury in large numbers of U.S. children. This study uses a large, multi-state dataset of child protective services reports for infants and young children under five years of age to examine risk factors and the effects of services in confirmed maltreatment investigations and recurrence over five years.

Methods

The Child Files of the National Child Abuse and Neglect Data System (NCANDS) for 2003-2007 were used to study confirmed CM reports to child protective services (CPS) using regression models and survival analysis among a cohort of children first reported during 2003.

Results

There were 1.2 million confirmed maltreatment reports to state child protective services agencies in 22 states during 2003-2007 in NCANDS, including 177,568 infants and young children under five years. 19.3% had a second confirmed CM report within 5 years. White race, inadequate housing and receiving public assistance were associated with significantly increased risk of CM recurrence. Infants and young children received more services and had less recurrence than did older children.

Conclusions

Infants and young children have different risk factors and receive different services than do older children in the CPS system. We need additional research to further assess and better target services for the special needs of infants, young children and their families if we are to protect them and reduce future child maltreatment.     

Nursing home admissions and long-stay conversions among persons with and without serious mental illness

The appropriateness of nursing homes for individuals with serious mental illness remains a controversial issue in long-term care policy more than a decade since the landmark U.S. Supreme Court Olmstead decision in 1999 , which affirmed the rights of persons with disabilities to live in their communities. Using national nursing home Minimum Data Set assessments from 2005, the authors compared the demographic, clinical, and functional characteristics of persons with and without serious mental illness newly admitted to nursing homes. They found that newly admitted people with serious mental illness were younger and more likely to become long-stay residents than those admitted with other conditions, despite a higher proportion of residents with serious mental illness, including the elderly, classified as low-care status. The most substantial and clinically significant difference for rates of low-care status 90 days after initial admission are for persons younger than 65 with serious mental illness versus those younger than 65 without serious mental illness (33% vs. 8.5%, or 3.9 times greater). There is a notable difference in low-care status between persons aged 65 and older with serious mental illness and those aged 65 and older without serious mental illness (14% vs. 6.6%, or 2.1 times greater). These results suggest that a substantial number of adults with serious mental illness residing in nursing homes may have the functional capacity to live in less restrictive environments.
