Estimation in the presence of incidental parameters

This paper considers the estimation of “structural” parameters when the number of unknown parameters increases with the sample size. Neyman and Scott (1948) had demonstrated that maximum likelihood estimators (MLE) of structural parameters may be inconsistent in this case. Patefield (1977) further observed that the asymptotic covariance matrix of the MLE is not equal to the inverse of the information matrix. In this paper we establish asymptotic properties of estimators (which include in particular the MLE) obtained via the usual likelihood approach when the incidental parameters are first replaced by their estimates (which are allowed to depend on the structural parameters). Conditions for consistency and asymptotic normality together with a proper formula for the asymptotic covariance matrix are given. The results are illustrated and applied to the problem of estimating linear functional relationships, and mild conditions on the incidental parameters for the MLE (or an adjusted MLE) to be consistent and asymptotically normal are obtained. These conditions are weaker than those imposed by previous authors.     

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.     

Parents’ Decision Making and Their Information Needs Concerning Treatments for Child Anxiety: Implications for Family-Centered Practice

Collaborative decision making is a central feature of family-centered practice and is important to families in treatment planning. This study explored parents’ preferences for decision making involvement and their information needs regarding treatment for child anxiety. Qualitative interviews conducted with 19 parents revealed four main themes: (1) parents regard themselves as protectors, (2) parents desire involvement in decision making, (3) information is key in decision making, and (4) not all treatments are perceived as equal. Parents reported a strong desire to maintain control over the final treatment decision. They preferred a wide range of information about treatment and the health-care provider. Implications for implementing family-centered practice are discussed.     

An Integral Approach to Mental Health Recovery: Implications for Social Work

The term recovery has become increasingly popular in the area of mental health care. Recently, it has been described by policy makers as the guiding vision for transforming the mental health system. Problematic, however, is that a lack of clarity continues to exist regarding how recovery is to be defined. Definitional attempts often appear to have competing opinions about what the concept exactly stands for. This causes confusion for both professionals and consumers desiring to adopt a recovery approach. Ken Wilber's integral theory is presented as a framework for organizing and connecting various viewpoints related to the “recovery” concept. Implications for social work are discussed.     

Racial inequality and social control: Historical and contemporary patterns in the U.S. South

Research dealing with disproportionate criminality, arrest, and incarceration among African Americans has tended to emphasize cultural, familial, and structural differences between racial groups while at the same time neglecting patterns and processes of race‐ and class‐based antagonism and subordination that are central, especially in the case of the U.S. South historically. We attempt to address this limitation by posing a model of the contemporary black‐white arrest differential across counties of one southern state. The model itself takes into consideration class‐ and race‐based subordination processes and their impact on local levels of stratification and arrest. Results suggest the continuing influence of racial competition and class dynamics. Racial competition enhances the arrest gap by disproportionately increasing unemployment and family dissolution among African Americans. The existence of a strong and concentrated traditional elite is shown to depress the racial gap, presumably by increasing poverty, unemployment, and family dissolution for both groups or by shaping what it means to go to jail, especially for blacks. In general, the arguments and findings presented suggest that criminological literature and theorizing should take note of local racial and political‐economic processes that, through the perpetuation of race and class inequality, reproduce disparate patterns of criminality, arrest, and incarceration.
