The impact of gender on gambling attitudes and behavior

Researchers have often attributed the consistent relation of gender and gambling behavior to gender role socialization. If they are correct, gender should affect different sets of gambling attitudes in a manner consistent with at least three aspects of gender role socialization: a double standard of morality, a guardian of the hearth role for women, and a dualism of orientations. A survey measuring gambling attitudes and behavior was sent to a sample of residents in North Dakota after legalization of several games of chance (e.g., blackjack). Gender affects behavior but only some of the specified attitudes. These mixed results may reflect changes in gender role socialization and the increasing legalization of gambling.     

Operating Characteristics of a Subset Selection Procedure Applied to a Hybrid Randomized Response Model

The operating characteristics (OCs) of a subset ranking and selection procedure are derived for the hybrid randomized response model developed by Jia and McDonald (2009 Jia, F., McDonald, G. (2009). Analyzing hybrid randomized response data with a binomial selection procedure. Commun. Statist. Theor. Meth. 38:784807.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]). The OCs include the probability of a correct P(CS), the individual selection probability γ_i, and the expected subset size E(S), under the slippage configuration or the equi-spaced configuration. An example comparing failure rates of contraceptive methods is used to illustrate the use of these new results.     

Option pricing for generalized distributions

The Black Scholes formula has been widely used to price financial instruments. The derivation of this formula is based on the assumption of lognormally distributed returns which is often in poor agreement with actual data. An option pricing formula based on the generalized beta of the second kind (GB2) is presented. This formula includes the Black Scholes formula as a special case and accommodates a wide variety of nonlognormally distributed returns. The sensitivity of option values to departures from the skewness and kurtosis associated with the lognormal distribution is investigated.     

Heteroscedasticity and Distributional Assumptions in the Censored Regression Model

Data censoring causes ordinary least-square estimators of linear models to be biased and inconsistent. The Tobit estimator yields consistent estimators in the presence of data censoring if the errors are normally distributed. However, nonnormality or heteroscedasticity results in the Tobit estimators being inconsistent. Various estimators have been proposed for circumventing the normality assumption. Some of these estimators include censored least absolute deviations (CLAD), symmetrically censored least-square (SCLS), and partially adaptive estimators. CLAD and SCLS will be consistent in the presence of heteroscedasticity; however, SCLS performs poorly in the presence of asymmetric errors. This article extends the partially adaptive estimation approach to accommodate possible heteroscedasticity as well as nonnormality. A simulation study is used to investigate the estimators’ relative performance in these settings. The partially adaptive censored regression estimators have little efficiency loss for censored normal errors and appear to outperform the Tobit and semiparametric estimators for nonnormal error distributions and be less sensitive to the presence of heteroscedasticity. An empirical example is considered, which supports these results.     

Intellectual disability and faith communities: perspectives of Catholic religious leaders

Faith communities create community and are important to many individuals with intellectual disability. However, relatively little is known about how intellectual disability is construed among faith leaders and the inclusion of people with intellectual disability in faith communities. To address these gaps in knowledge, we interviewed 12 Catholic priests, parochial vicars, and deacons to explore: their experiences with individuals with intellectual disability; their beliefs towards the involvement of individuals with intellectual disability within faith communities; and how religion informs their understanding of intellectual disability. We identified five religiously-anchored narratives of intellectual disability, and explore implications for individuals with intellectual disability and faith communities.
