Wealth Inequality in Black and White: Cultural and Structural Sources of the Racial Wealth Gap

Using data from the 2013 Survey of Consumer Finances, this research examines competing and complementary cultural and structural explanations of the sources of racial differences in wealth. We use OLS regression and quantile regression to identify the major individual-level sources of wealth differences between African Americans and whites. Whites have more favorable wealth characteristics than do African Americans on all of the variables in the analysis: gender of household head, bankruptcies, spending patterns, stock ownership, business ownership, home ownership, inheritance, educational attainment, income, occupation, age, and number of children. Cultural factors, having a female-headed family, spending patterns, and inheritance account for little of the racial wealth gap. Racial differences in income, stock ownership, and business ownership account for much of the explained racial wealth gap. Moreover, compared with whites, African Americans receive significantly lower wealth returns to education, age, income, stock ownership, and business ownership. We discuss the implications of our findings.     

The robust economic statistical design of the Hotelling's T2 chart

ABSTRACT

Economic statistical designs aim at minimizing the cost of process monitoring when a specific scenario or a set of estimated process and cost parameters is given. But, in practice the process may be affected by more than one scenario which may lead to severe cost penalties if the wrong design is used. Here, we investigate the robust economic statistical design (RESD) of the T² chart in an attempt to reduce these cost penalties when there are multiple scenarios. Our method is to employ the genetic algorithm (GA) optimization method to minimize the total expected monitoring cost across all distinct scenarios. We illustrate the effectiveness of the method using two numerical examples. Simulation studies indicate that robust economic statistical designs should be encouraged in practice.     

The relationship between criminality and home background

There are two extensive literatures which deal with this subject. One is that on criminality, defining the distinctions between morality and cultural definitions. The other is on how parents ought to influence their offspring. And there is also a smaller literative on the causal or statistical relationship between the two. This research tradition attempts to isolate particular hypotheses—like lone parents or genetics. What is missing is both a study of why certain influences are significant, and a connection between the actual cases of criminality and criminals' own experiences of their parents. For this purpose lengthy semistructured interviews with young offenders were carried out, exploring their memories and perceptions of home life and their attitudes to their parents and their subsequent experiences. This paper discusses the factors that the interviewees raised consistently, openly and articulately; violence in the home, neglect, laissez-faire: and turning to peer groups for alternative support. At the heart of the evidence lies a lack of dialogue and the perception of a lack of active interest in them by parents. The consequences are discussed, including the inability to develop normal social relationships, leading to frustration and the repetition of violence in the home in different circumstances.     

Random sampling from the watson distribution

An envelope-rejection method is used to generate random variates from the Watson distribution. The method is compact and is competitive with, if not superior to, the existing sampling algorithms. For the girdle form of the Watson distribution, a faster algorithm is proposed. As a result, Johnson's sampling algorithm for the Bingham distribution is improved.     

Critical Diversity and Departmental Rankings in Sociology

This paper examines whether racial and gender diversity are related to the rankings of sociology programs at research universities. It uses data from the 2011 National Academy of Sciences (NAS) Rankings of U.S. Research Universities to examine the competing expectations of the “critical diversity perspective” and the “diversity as process-loss” perspective. The results are counter to the expectations of the diversity as process-loss perspective, which predicts that diversity (and efforts to achieve it) are harmful to organizations. The results are fully consistent with the critical diversity as value-in-diversity perspective, which predicts that as organizations become more diverse, they benefit relative to their competitors. The results show that, net of research rankings, 1995 rankings, faculty publication rates, visibility of faculty publications, percentage of faculty with grants, scholarly awards, program size, region, and whether the institution is public or private, diversity is positively associated with departmental rankings of sociology programs in research universities. The implications of these findings for diversity in sociology are discussed.     

Prevalence and risk and protective factors associated with HIV-related behavior among transgender people in Hong Kong

Abstract

This paper presents findings from the first large-scale quantitative study into HIV-related behavior among transgender people in Hong Kong. A survey of 195 transgender people found that only one-third of those who had engaged in sexual behavior in the past 3?months reported consistent condom use. Stable relationships, beliefs in low HIV transmission risk, and condom inaccessibility were cited as reasons for inconsistent condom use. The HIV testing figures were also strikingly low. This study demonstrates an urgent need for addressing HIV issues among transgender people in Hong Kong as there are currently no such specific services.
