The Impact of Sound in Modern Multiline Video Slot Machine Play

Slot machine wins and losses have distinctive, measurable, physiological effects on players. The contributing factors to these effects remain under-explored. We believe that sound is one of these key contributing factors. Sound plays an important role in reinforcement, and thus on arousal level and stress response of players. It is the use of sound for positive reinforcement in particular that we believe influences the player. In the current study, we investigate the role that sound plays in psychophysical responses to slot machine play. A total of 96 gamblers played a slot machine simulator with and without sound being paired with reinforcement. Skin conductance responses and heart rate, as well as subjective judgments about the gambling experience were examined. The results showed that the sound influenced the arousal of participants both psychophysically and psychologically. The sound also influenced players’ preferences, with the majority of players preferring to play slot machines that were accompanied by winning sounds. The sounds also caused players to significantly overestimate the number of times they won while playing the slot machine.     

Co‐located Nonprofit Centers

Nonprofit centers are organized to house individual nonprofits “under one roof” to enhance their efficiency and effectiveness and to offer shared services to diminish administrative load. This post‐occupancy tenant satisfaction survey of three such US centers represents the first empirical analysis of such organizations. We find that nonprofit tenants (N = 118) initially co‐located due to the leasing price and the new physical environment (free parking and safety). Nearly all nonprofit tenants wished to remain at their nonprofit centers, largely for the same reasons that brought them there. The article then discusses strategies to achieve the high response rates attained in this study. It concludes with some implications for nonprofit centers, communities, and nonprofit staff—now and in the future, including lower occupancy costs and enhanced quality of nonprofits’ workspace.     

Intermediaries and destination reputations: explaining flows of skilled migration

ABSTRACT

Governments have increasingly commercialised their migration services, which has fuelled a mushrooming migration industry creating a ripe context for the central role of migration intermediaries. It is therefore timely to explore the new actors responsible for shaping contemporary flows of skilled migration. Drawing on the work of existing studies and a wide variety of secondary data, we argue that the range of intermediaries who have emerged as a result of the commercialisation process, have been poorly understood in the skilled migration and migration industries literatures. Discussion of these actors sheds important theoretical light on how intermediaries, destination reputations and skilled migration flows intersect. Accordingly, we outline six propositions that identify the interconnected relationship between migration intermediaries, reputation and skilled migration flows.     

An application of a multi‐stage strategy involving confidence intervals to evaluate whether a response rate is favourable or not

In early clinical development of new medicines, a single‐arm study with a limited number of patients is often used to provide a preliminary assessment of a response rate. A multi‐stage design may be indicated, especially when the first stage should only include very few patients so as to enable rapid identification of an ineffective drug. We used decision rules based on several types of nominal confidence intervals to evaluate a three‐stage design for a study that includes at most 30 patients. For each decision rule, we used exact binomial calculations to determine the probability of continuing to further stages as well as to evaluate Type I and Type II error rates. Examples are provided to illustrate the methods for evaluating alternative decision rules and to provide guidance on how to extend the methods to situations with modifications to the number of stages or number of patients per stage in the study design.

On the small sample properties of norm-restricted maximum likelihood estimators for logistic regression models

This paper develops alternatives to maximum likelihood estimators (MLE) for logistic regression models and compares the mean squared error (MSE) of the estimators. The MLE for the vector of underlying success probabilities has low MSE only when the true probabilities are extreme (i.e., near 0 or 1). Extreme probabilities correspond to logistic regression parameter vectors which are large in norm. A competing “restricted” MLE and an empirical version of it are suggested as estimators with better performance than the MLE for central probabilities. An approximate EM-algorithm for estimating the restriction is described. As in the case of normal theory ridge estimators, the proposed estimators are shown to be formally derivable by Bayes and empirical Bayes arguments. The small sample operating characteristics of the proposed estimators are compared to the MLE via a simulation study; both the estimation of individual probabilities and of logistic parameters are considered.     

A Psychometric Evaluation of the DSM-IV Pathological Gambling Diagnostic Criteria

Specific diagnostic criteria for pathological gambling (PG) have been available for 25 years, since the publication of DSM-III. Little research has examined the psychometric performance of the diagnostic criteria. The goal of the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project was to examine the sensitivity, specificity and predictive values of the DSM-IV PG criteria for psychiatric outpatients who screened positive for a gambling problem. A total of 1709 psychiatric outpatients were evaluated with a semistructured diagnostic interview for PG. Of all patients 88 screened positive for PG, 40 of whom met DSM-IV diagnostic criteria for a lifetime history of PG. All ten DSM-IV criteria were significantly more frequent in the PG group. The sensitivity of the criteria ranged from 25.0% to 90.0% (mean = 67.8%), whereas specificity ranged from 62.5% to 100% (mean = 81.9%). Positive predictive values ranged from 64.1% to 100% (mean = 78.9%), and negative predictive values ranged from 61.5% to 90.7% (mean = 77.1%). Guidelines are recommended for determining whether a diagnostic criterion should be retained as part of the set of diagnostic criteria, and our results suggested that two of the DSM-IV PG criteria are candidates for elimination (criterion 8—commitment of illegal acts; criterion 10—reliance on others for financial assistance to relieve a desperate financial problem).     

Daily data collection of sexual and other health‐related behaviors

This article documents some findings of a sociological research project which was done in West Germany from 1970 ‐ 1973 (Dannecker/Reiche 1974). 139 contact‐persons, chosen by the authors, distributed 1617 questionnaires to homosexuals. 789 were filled out and sent back and constitute our sample.

The complete research project comprises six themes: coming out; homosexual subculture; homosexual friendships; sexuality of homosexuals; jobs and the employments of homosexuals; the collective neurosis of homosexuals.     

Body Image among Women with Physical Disabilities: Internalization of Norms and Reactions to Nonconformity

Abstract

Body norms for women are based on stereotypical gender expectations regarding physical appearance. Although women in general are exposed to societal standards of the ideal body, women with physical disabilities encounter unique circumstances in meeting these expectations. Women with physical disabilities are often stigmatized because they violate norms of body aesthetics and body shape. This research examines the extent to which women with physical disabilities internalize body norms and the reactions these women have to their nonconformity to societal body standards. In-depth tape-recorded interviews, investigating a variety of social and interpersonal issues, were conducted with 21 female university students with physical disabilities. Using content analysis, the researchers examined the interviews for common themes and patterns relating to body image. The major categories that emerged were (1) awareness of body norms, (2) compliance with body norms, and (3) reactions to nonconformity to body norms. The study illustrates that women with physical disabilities have two general reactions to societal expectations of the ideal female body: emotional responses and stigma management. The lack of questioning of cultural body norms by respondents is discussed as it relates to the rural, small town study location.

Abstract

This paper describes a content analysis in which 902 television commercials were coded for religious symbolism, science and professional expertise. Evidence obtained from this exploratory study is neither definitive nor exhaustive, but it is suggestive and provocative. Data show that religious symbolism is rarely found in television ads, and commercials using science or professional expertise constituted only nine percent of the sample. Apparently, television advertisers do not view appeals to religion or science as especially helpful for selling products.
