Bayesian and likelihood inference for cure rates based on defective inverse Gaussian regression models

Failure time models are considered when there is a subpopulation of individuals that is immune, or not susceptible, to an event of interest. Such models are of considerable interest in biostatistics. The most common approach is to postulate a proportion p of immunes or long-term survivors and to use a mixture model [5]. This paper introduces the defective inverse Gaussian model as a cure model and examines the use of the Gibbs sampler together with a data augmentation algorithm to study Bayesian inferences both for the cured fraction and the regression parameters. The results of the Bayesian and likelihood approaches are illustrated on two real data sets.     

Female Authority and Dominion: Discourse and Distinctions of Heavy Metal Scholarship

From its inception, both outsiders and insiders have associated heavy metal with men and masculinity. Some have even maintained that metal culture is hostile territory for women. Despite this, a significant proportion of writers who have documented, analysed, and indeed celebrated heavy metal has been women, from the groundbreaking sociological studies of Deena Weinstein and Donna Gaines, to the recent ethnographic work of Emma Baulch. This article provides a preliminary investigation of this historical phenomenon and what it can reveal about the ever complex, constantly changing relationship between gender and power in metal.     

The Perception of Societal Models of Power Distribution by Recent Male College Graduates

Abstract

This study examines the perception of power among young adult males. A sampleof 1971 male graduates of a state university were asked in 1974 to choose from among pluralistic and elitist models of power in the U.S. The correlates of the various perceptions of power were elaborated using political attitudes, degree of political activism, change in political beliefs, locus of control, and status inconsistency. The findings were that: (1) the respondents tended to perceive an elitist model, although they preferred a pluralist model; and (2) those most likely to perceive power in elitist terms were activists, those with changed political beliefs, those most status inconsistent, and those with external locus of control.     

Public support for Hispanic deportation in the United States: the effects of ethnic prejudice and perceptions of economic competition in a period of economic distress

This paper investigates the effect of ethnic prejudice and perceived economic competition on support for deportation and alternative policy options concerning the handling of undocumented immigrants. Using a national survey conducted in early 2009, data are analysed using bivariate and multinomial regression techniques. Ethnic prejudice and perceived economic competition were found to be significantly related to support for deportation in the face of alternative options, controlling for the effects of age, sex, employment status, nativity, race, party identification, and education. Furthermore, majority support for deportation was found among conservatives, moderates, Republicans, and Independents. Even among liberals and Democrats, substantial numbers supported deportation. During the recent economic recession, perceived economic competition and ethnic prejudice were dominant influences on deportation preferences, and deportation appears to have become a mainstream policy option. However, we speculate that deportation preferences are relatively shallow and unstable owing partly to the dependence of immigration public opinion on economic cycles, and, ultimately, the unfeasibility of deportation as a policy option.
