Indexes of Racial Residential Segregation for 109 Cities in the United States, 1940 to 1970

Abstract

An index of racial residential segregation for a city may be calculated from census data reporting the number of white and nonwhite households resident in each city block. Such an index summarizes the dissimilarity in residential location of the two groups. Segregation indexes for 109 cities for the years 1940, 1950, and 1960 were published in Taeuber and Taeuber Negroes in Cities (1965).

Segregation indexes for 109 cities for 1970, together with the previously published indexes for the three earlier census dates, are presented in Table 1. The trend data from 1940 through 1970 refer to residential segregation of whites and nonwhites. For 1970 only, segregation indexes are also presented comparing whites and Negroes.

The trend data reveal a distinctive pattern of change during each of the three decades. From 1960 to 1970, declines in segregation prevailed among cities in each region of the country.

The indexes for 1970 were calculated from Public Use Summary Tapes issued by the Bureau of the Census. Certain difficulties were encountered in the use of these tapes. A methodological appendix describes the data source and retrieval procedure for calculation of city segregation indexes for 1970.     

Addressing the measurement challenge in elder abuse interventions: need for a severity framework

ABSTRACT

The field of elder abuse is evolving toward an emphasis on intervention research. However, researchers currently rely on binary approaches to measure elder abuse phenomena, which fail to capture changes in problem status over the course of intervention. This commentary develops a case for severity as a framework to operationalize and measure elder abuse in intervention research and practice. A severity framework provides enhanced elder abuse measurement responsiveness and aligns with the dominant client-centered, harm-reduction clinical approach to intervening with elder abuse cases.     

The Impact of Information Sharing on Supply Chain Performance under Asymmetric Information

The use of screening contracts is a common approach to solve supply chain coordination problems under asymmetric information. One main assumption in this context is that managers without specific incentives would rather use their private information strategically than reveal it truthfully. This harms supply chain performance. This study investigates the impact of information sharing in a principal‐agent setting that is typical for many supply chain transactions. We conduct a laboratory experiment to test whether information sharing has an influence on supply chain coordination. We find that information sharing within the supply chain has two positive effects. First, information sharing reduces the inefficiencies resulting from information deficits if there is a certain amount of trust in the supply chain. Second, communication can limit out‐of‐equilibrium behavior with a small impact on the firm's own payoff, but a large impact on the supply chain partner. Furthermore, we find that both effects are amplified when communication takes place in an environment that allows the less informed supply chain party to punish or to reward the better informed party. Although our extended mechanisms substantially enhance the poor performance of the theoretically optimal coordination contract menu, we find no mechanism that implements supply chain performance superior to the theoretically predicted second‐best level.     

Empathy in Social Work

ABSTRACT

A dominant conceptualization of empathy in social work practice and education, provided by Karen Gerdes and Elizabeth Segal, relies heavily on the simulation theory adopted directly from the cognitive neurosciences. The aim was to critically challenge such a view by reporting on some recent empirical findings from the field in which professional social workers were interviewed about their experience of empathy in working with forced migrants. The findings support a phenomenological, critical account of simulation theory and provide evidence that empathy is constituted as a direct social perception of the other's experience. It was concluded that simulation theory is insufficient in providing an exhaustive approach for the professional use of empathy in social work practice and education.     

Negotiating and enacting musical innovation and continuity: How some torres strait islander songwriters incorporate traditional dance chants within contemporary songs

Many Indigenous peoples worldwide engage with popular music and popular music forms, often striving to find a balance between traditional and contemporary influences.

This article uses ethnographic data from Australian Torres Strait Islander songwriters to explore the processes and rationales they use when incorporating traditional dance chants within contemporary songs.

The research demonstrates some of their processes of innovation and continuation while they negotiate crucial cultural and community politics that inform not only music and dance but also other forms of contemporary Indigenous artistic expression.

The songwriters perceive themselves as creators but creators who must also work within the cultural, social and aesthetic dictates of their communities.     

Addressing Ethnicity in Social Care Research

This article surveys recent developments in relation to the dimensions of ethnicity and ethnic disadvantage in social policy research and practice, with a focus on social care. While there has been limited increase in attention to ethnicity within general policy discussion and increasing sophistication within specialist debates, advances in theory and methodology have largely failed to penetrate the research mainstream, let alone policy or practice. This is a long‐standing problem. We advocate more focused consideration of ethnicity and ethnic disadvantage at all levels. Failure to do so creates the risk of social policy research being left behind in understanding rapid changes in ethnic minority demographics and patterns of migration, with increasing disadvantage to minorities.     

Statistical aspects of W. D. Fisher's method of optimal aggregation

W. D. Fisher's approach to approximating a known linear model y=Ax by an aggregation-disaggregation sequence involves a moment matrix M which is supposed to be known. This paper investigates the statistical problems arising when M is not known. As an example we consider the open static Leontief model with A being the Leontief inverse. Under the assumption that the exogenous variables are multinormal with zero mean, tests and confidence intervals for the loss of information are given. The use of maximum entropy estimation of M for insufficient data is discussed. Statistical procedures to evaluate the goodness of aggregation-disaggregation of a time series of matrices A are also described.
