Cognitive, Dispositional, and Psychophysiological Correlates of Dependent Slot Machine Gambling in Young People

In Study 1, young dependent and nondependent slot machine gamblers were interviewed, assessed for locus of control and administered the Eysenck Personality Questionnaire. Dependent gamblers were revealed as reliably more internal in terms of locus of control than their nondependent counterparts, and, in the interview, were much more likely to affirm that they could exercise control over the slot machines they played. Dependent gamblers registered higher psychoticism scores than both the nondependent gamblers and appropriate age-group norms. Their high psychoticism scores resonated well with interview revelations that boredom mitigation frequent underlay dependent gambling.
In Study 2, blood pressure was monitored in dependent and nondependent gamblers at rest and before, during and after slot machine play. Subjects were given £5 for this purpose and the time it took them to use up this money was recorded, as was the extent of any returns they received. They were also asked how much they expected to recoup. The £5 lasted a similar amount of time for the two groups, and they managed similar rates of return on their stake. However, the dependent gamblers expected to win more than the nondependent gamblers and their estimates of returns exceeded what they actually recouped. Slot machine play was associated with an increase in blood pressure, and while groups did not differ in terms of the magnitude of the rise provoked, there was a general trend for dependent gamblers to show lower basal levels of cardiovascular activity, although this was statistically reliable only in the case of diastolic blood pressure.     

The family on television: Evaluation of gender roles in situation comedy

This study investigated whether television domestic comedies’ depictions of gender roles within the family have changed in the past 40 years. Ten domestic comedies were selected based on their popularity and the inclusion of siblings. These series were divided into two groups—pre and post 1984, given the time span covered by the series and the series’ setting. College students screened three representative episodes and made subsequent judgments on the portrayals of similarity, equality, and dominance, family satisfaction and family stability in the spousal, sibling, and familial relationships. Results indicated the depictions of gender roles fluctuated throughout the period, with peaks in satisfaction and stability ratings in the 1950s and mid-1980s. More recent domestic comedies contained less positive depictions, specifically displaying more dominance and less satisfaction and stability. Subjects reported families that were more distressed were less desirable and less like their own.     

Virtue as the basis of engineering ethics

This paper explores the nature of virtue theory as applied to engineering practice. It links virtue to specific areas of practice such as the selection of ends, devotion to service, the formation of justified belief, the conduct of dialogue, the taking of actions, and exercises of the will. These areas are related to a culture of virtue in which an engineering society creates the conditions enabling acts of virtue and celebrates individuals and their acts which exemplify identified virtues. The result is a basis for engineering ethics which draws attention to the impetus for an ethically sound life. An earlier version of this paper was presented by the author at a mini-conference, Practicing and Teaching Ethics in Engineering and Computing, held during the Sixth Annual Meeting of the Association for Practical and Professional Ethics, Washington, D.C., March 8–9, 1997.     

Evolution of the African American Family Personality: Considerations for Family Therapy

Both internal and external factors help to determine the personality of the African American family. Personality traits of the African American family include adherence to historical values, diversity in family structure, and family communication. A review of the history of the African American family from its African roots to contemporary America is presented here.     

The estimation of ultrametric and path length trees from rectangular proximity data

A least-squares algorithm for fitting ultrametric and path length or additive trees to two-way, two-mode proximity data is presented. The algorithm utilizes a penalty function to enforce the ultrametric inequality generalized for asymmetric, and generally rectangular (rather than square) proximity matrices in estimating an ultrametric tree. This stage is used in an alternating least-squares fashion with closed-form formulas for estimating path length constants for deriving path length trees. The algorithm is evaluated via two Monte Carlo studies. Examples of fitting ultrametric and path length trees are presented.G.

The similarity and diversity of semantic relations

There is a rich variety of semantic relations in natural languages. Subjects’ perceptions of similarities among relations were studied for a wider variety of relations than had been used in previous studies. Forty subjects sorted 31 cards bearing five example pairs of each of 31 semantic relations. Subjects were able both to distinguish the relations and to perceive their similarities. A hierarchical clustering analysis of the sorting data indicated that the subjects perceived five families of semantic relations (contrasts, class inclusion, similars, case relations, and part-wholes). The five families were distinguished in terms of three properties of semantic relations: contrasting/noncontrasting, logical/pragmatic, and inclusion/noninclusion. Within each family, relations also were sorted in ways consistent with their defining properties. Relations were therefore viewed not as unanalyzable primitives, but in terms of the relational properties that distinguished them.
