The More Things Change, the More They Stay the Same: The Elusive Search for Racial Equity in Higher Education

In 1965, when affirmative action officially became part of the national consensus to achieve racial social justice, it was based on the compelling justification of establishing equality and remedying the effects of past discrimination. Since then, there has been a slow but steady shift from "equity" to "diversity" as its rationale. The shift has had a negative effect on achieving the original goal of racial equality. The diversity rationale has permitted parallel procedures to evolve that provided majority students with an even larger differential advantage than that conferred on minority students by affirmative action. In addition, we continue to have massive segregation. Minorities are concentrated in second level schools in urban areas, while whites are concentrated in higher quality institutions in the educational suburbs. It is without factual or legal foundation that whites can argue that they (relative to minorities) are the victims of discrimination through unfair and unequal educational policies and practices that determine access to higher education.     

Reconsidering the Marielito Legacy: Race/Ethnicity,Nativity, and Homicide Motives*

Objective. This article investigates how race/ethnicity is associated with specific types of violent crime such as killings between intimates, robbery homicide, or drug‐related killings. We extend the study of the role of race and ethnicity for violence by examining five ethnic/immigrant groups, including the Mariel Cubans—a group singled out by many as particularly drug‐crime‐prone. Methods. Using 1980 through 1990 homicide data for the City of Miami, we use multinomial logistic regression to examine the association between race/ethnicity, nativity, and several types of homicide motives. Results. Contrary to popular expectations, ethnicity and immigration status rarely play a role in the types of homicide involvement of victims or violators. Incident characteristics, such as multiple offenders, or gender and age, were consistently more important influences in shaping homicide circumstances. Conclusions. The analyses revealed few significant relationships between immigration status and homicide motives, suggesting that immigrant groups like the Marielitos have more in common with native groups' experiences of criminal violence than is commonly assumed.     

Anova and minque type of estimators for the one-way random effects model

The one-way random effects model with unequal variances and unequal sample sizes is considered. Estimation of the variances, variance of a single observation (total variance), and the standard error of the unweighted mean are considered. Precision of the Analysis of Variance and Unweighted Sums of Squares type of estimators and the Minimum Norm Quadratic Unbiased Estimators with a priori weights are examined.     

The Feeling Edge of Culture

During the 1960s, the new generation changed the American Creed by deemphasizing sensitivity to evidence, emphasizing feelings and deductive thought, while assuming an adversarial position against the sociopolitical order and embracing the American Black's struggle against racism. Driven by pain, fueled by fear and anger and oriented by existential values of being the Civil Rights Movement, sought to actualize political values of justice and equality. As peaceful demonstrations dwindled, violence increased, converting individual anger to social rage. Anger's cognitive structure changed the concept of society into a dichotomy of Black victims and Ulhite oppressors, forming an ethic of sensitivity with victims occupying the moral high ground. Pain and tragedy were banished from view and blamed on oppressors as individual identities divested civil traits and acquired cultural identity, disuniting the civil society. Rubbing against the American Creed, the ethic ofsensitivity produced a feeling of malaise posing a threat to mentaL health.     

Estimation of relaxation time distributions in magnetic resonance imaging

Magnetic resonance imaging techniques can be used to measure some biophysical properties of tissue. In this context, the T₂ relaxation time is an important parameter for soft‐tissue contrast. The authors develop a new technique to estimate the integral of the distribution of T₂ relaxation time without imposing any constraint other than the monotonicity of the underlying cumulative relaxation time distribution. They explore the properties of the estimation and its applications for the analysis of breast tissue data. As they show, an extension of linear discriminant analysis is found to distinguish well between two classes of breast tissue.     

Bayesian Binomial Regression: Predicting Survival at a Trauma Center

Standard methods for analyzing binomial regression data rely on asymptotic inferences. Bayesian methods can be performed using simple computations, and they apply for any sample size. We provide a relatively complete discussion of Bayesian inferences for binomial regression with emphasis on inferences for the probability of “success.” Furthermore, we illustrate diagnostic tools, perform model selection among nonnested models, and examine the sensitivity of the Bayesian methods.
