“There are Two People at Work that I'm Fairly Certain are Black”: Uncertainty and Deliberative Thinking in Blind Race Attribution

Geneticists, biologists, social scientists, and humanist scholars have powerfully critiqued race as a stable set of biological categories. Despite this, in everyday life, race is consistently assumed to be visually available in physical features. Racial categories also continue to be used in scientific and social scientific research as if they were self‐evident and real. In this study, I examine the role of visual perception in the construction of racial categories and their recalcitrance in everyday thought and interaction. My observations are based on in‐depth interviews with 25 blind people, which highlight the unique features of their nonvisual, non‐appearance‐based experiences of race.     

Identification and Inference With Many Invalid Instruments

We study estimation and inference in settings where the interest is in the effect of a potentially endogenous regressor on some outcome. To address the endogeneity, we exploit the presence of additional variables. Like conventional instrumental variables, these variables are correlated with the endogenous regressor. However, unlike conventional instrumental variables, they also have direct effects on the outcome, and thus are “invalid” instruments. Our novel identifying assumption is that the direct effects of these invalid instruments are uncorrelated with the effects of the instruments on the endogenous regressor. We show that in this case the limited-information-maximum-likelihood (liml) estimator is no longer consistent, but that a modification of the bias-corrected two-stage-least-square (tsls) estimator is consistent. We also show that conventional tests for over-identifying restrictions, adapted to the many instruments setting, can be used to test for the presence of these direct effects. We recommend that empirical researchers carry out such tests and compare estimates based on liml and the modified version of bias-corrected tsls. We illustrate in the context of two applications that such practice can be illuminating, and that our novel identifying assumption has substantive empirical content.     

Horizons for strategic planning

In this paper we present a normative model for setting time horizons for planning. Provided that certain conditions are met, we can state that only part of the future is relevant for present strategic planning, and a study of the future beyond that time horizons is a waste of resources.Following the introduction the impact of predetermined planning horizon on planning is discussed. Next, the model is presented: the problem is defined, developed and solved. The discussion of the model is designed to incorporate—and to show its implication on—existing views and methods for setting time horizons for strategic planning. Thus, simplifying assumptions which facilitate the mathematical solution of the problem, are discussed and relaxed in order to show how realistic situations are illuminated by the model.     

Effect of individual differences in nonverbal expressiveness on transmission of emotion

This study tested the possibility that individual differences in nonverbal expressiveness may function as a mediating factor in the transmission of emotion through social comparison. In a quasi-experimental design, small groups consisting of one expressive person and two unexpressive people were created in which the participants sat facing each other without talking for two minutes. Self-report measures of mood indicated that the feelings of the unexpressive people were influenced by the expressive people but the expressive people were relatively unlikely to be influenced by the unexpressive people. The findings have implications for the role of nonverbal communication in the emotional side of group interaction.This research was supported by NIMH Grant #R03MH31453 and by an Intramural Research Grant from UC Riverside to Howard Friedman. We would like to thank Louise M. Prince and Dan Segall for their assistance and Eliot Smith, Joe Schwartz and Keith Widaman for suggestions.     

Noah: a story of peacebuilding,nonviolence, reconciliation,and healing

ABSTRACT

For years there has been a failure to show the relevance between the application of religious text within social work and the social sciences. This paper provides a functional framework on the reason for the separation between social sciences and religious studies and then uses the Genesis account of Noah and the flood to show how the two can be integrated for peacebuilding, reconciliation, and healing. The paper applies the Noah story to micro, mezzo, and macro applications of social work practice and concludes with a call for a deeper integration of religious text into social work practice.     

Housing Tenure and Residential Segregation in Metropolitan America

Homeownership, a symbol of the American dream, is one of the primary ways through which families accumulate wealth, particularly for blacks and Hispanics. Surprisingly, no study has explicitly documented the segregation of minority owners and renters from whites. Using data from Census 2000, this study aims to fill this gap. Analyses here reveal that the segregation of black renters relative to whites is significantly lower than the segregation of black owners from whites, controlling for relevant socioeconomic and demographic factors, contrary to the notion that homeownership represents an endpoint in the residential assimilation process. The patterns for Hispanics and Asians conform more to expectations under the spatial assimilation model. The findings here suggest that race and ethnicity continue to be as important in shaping residential segregation as socioeconomic status, and raise concerns about the benefits of homeownership, particularly for blacks.
