On probabilistic parametric inference

This paper formulates a theory of probabilistic parametric inference and explores the limits of its applicability. Unlike Bayesian statistical models, the system does not comprise prior probability distributions. Objectivity is imposed on the theory: a particular direct probability density should always result in the same posterior probability distribution. For calibrated posterior probability distributions it is possible to construct credible regions with posterior-probability content equal to the coverage of the regions, but the calibration is not generally preserved under marginalization. As an application of the theory, the paper also constructs a filter for linear Gauss–Markov stochastic processes with unspecified initial conditions.     

Factors related to attitudes toward diversity in Australia,Malaysia, and Puerto Rico

In this study, we tested social identity complexity theory (Roccas & Brewer, 2002) in relation to attitudes toward diversity and the associated variables of patriotism, nationalism, religiosity, aggression, and sense of self (well-being) in a cross-cultural study of 398 Malaysian, 239 Australian, and 201 Puerto Rican students. Puerto Ricans reported the most positive attitudes toward diversity, followed by Australians, and finally Malaysians. For Puerto Ricans, pro-diversity attitudes were predicted by a positive correlation with constructive patriotism and a negative correlation with blind patriotism. For Australians, pro-diversity attitudes were predicted by a positive association with constructive patriotism, a negative association with traditional nationalism, and a negative association with physical aggression. For Malaysians, pro-diversity attitudes were predicted by positive relationships with all of the following variables: constructive patriotism, traditional nationalism, verbal aggression, hostility, and the need to bolster self through idealizing others. These results support social identity complexity theory and partially support associated predictions for Australians, Puerto Ricans, and some of the predictions for Malaysians. The results are explained in terms of local cultural contexts that may not easily be understood by a simple understanding of the variables that were measured.     

STATE LIQUOR LICENSING, IMPLICIT CONTRACTING, AND DRY/WET COUNTIES

Local option liquor laws are generally interpreted as granting voters the right to choose between allowing and prohibiting alcoholic beverage sales. This paper argues that the real choice confronting voters is between legal sales according to state-prescribed rules and illegal sales according to an informal set of locally-determined rules. Given this choice, rational voters will choose the option with the lower relative price. State laws restricting the number of licenses that can be issued in legally wet jurisdictions prove to be more powerful than religious preferences in explaining the pattern of dry counties.     

Current drug education policies in NCAA institutions: perceptions of head athletic trainers

This study compared the perceptions of head athletic trainers (HATS) from NCAA member Divisions I, II, and III regarding current athletic department drug education policies in their institutions. A Web-based questionnaire collected responses from 353 HATS. Drug education programs focused more on providing information about the negative consequences of drugs than changing the attitudes and behaviors of students in relation to drug use. More Division I and II schools offered comprehensive ATOD education programs to their athletes compared to Division III schools; however, the majority of these programs were not scheduled on a regular basis. HATS in all divisions reported that the abuse of alcohol and other drugs by student athletes during and after athletic and social events was a significant concern and indicated the importance of scheduling drug education programs closer to such events. Majority of HATS did not view participating in the drug education programs as part of their professional duties; however, they expressed an interest to increase their involvement in these activities.     

The Discursive Construction of Death

Two people in distress over the death of a parent converse with each other about the loss. Death must convey some meaning. The attempt at creating such meaning appears to be a function of the comfort to be derived to the survivors. To the extent that death is seen as transition to some other form of further existence, e.g., to some place of tranquility, the survivors remain at peace. That vision, however, presents considerable difficulties since it demands some form of contact with the deceased. In the absence of such contact, doubts remain and the survivors suffer from a sense of abandonment and apathy due to the lack of meaning.     

Minimum Hellinger distance estimators for multivariate distributions from the Johnson system

In this paper, we study minimum Hellinger distance estimators (MHDEs) for multivariate distributions from the Johnson system. We prove some properties of these estimators, such as consistency and asymptotic normality, and show that they represent a robust alternative for other existing estimators.     

Empirical Considerations on the Problem of Social Integration*

The present study analyzes differences in perception of neighborhood and residential mobility as related to formal and informal participation. Results show that perceived similarity is related to neighborhood participation, while residential mobility is related to formal group membership. These relationships, with very few exceptions, seem to persist even in the presence of other control variables like age, education and religion. A significant proportion of the urban community participates frequently with neighbors and belongs to church and other formal groups. These activities are generally high in the suburb and low in the inner city regardless of differences in perception of neighborhood and residential mobility except for membership in organizational groups: the high membership in the suburb occurs under conditions of perceived similarity. The theoretical implications suggest a re-evaluation of the mode of life in the modern urban community and emphasize the significance of taking the perceptual as well as the behavioral context into account in sociological analysis.     

Individual and ecological assets and positive developmental trajectories among gang and community-based organization youth

The Search Institute framework for conceptualizing developmental assets was used in a longitudinal study of African American male youth involved in gangs or in community-based organizations (CBOs) serving youth. Analyses of intraindividual change indicated that individual and ecological assets are linked to positive developmental trajectories among these youth.
