String decomposition of full-period tausworthe sequences

Because of their nice properties relative to the frequency of occurrence of n-tuples, Tausworthe sequences have been used frequently in recent years as the basis for random number generators. This paper describes a similar result relative to the frequency of occurrence of maximal-length strings of like bits. In particular, for any full-period Tausworthe sequence, the distribution of string lengths is precisely equal to the expected distribution of string lengths for a truly random bit sequence of comparable size.     

A counterexample to a conjecture of Schwartz

In 1990, motivated by applications in the social sciences, Thomas Schwartz made a conjecture about tournaments which would have had numerous attractive consequences. In particular, it implied that there is no tournament with a partition A, B of its vertex set, such that every transitive subset of A is in the out-neighbour set of some vertex in B, and vice versa. But in fact there is such a tournament, as we show in this article, and so Schwartz’ conjecture is false. Our proof is non-constructive and uses the probabilistic method.     

Applying Social Learning Theory of Career Decision Making to Gay,Lesbian, Bisexual,Transgender, and Questioning Young Adults

Incorporating J. D. Krumboltz's (1979) social learning theory of career decision making, the author explores career development issues for gay, lesbian, bisexual, transgender, and questioning (GLBTQ) adolescents and young adults. Unique challenges for the GLBTQ population are discussed, specific recommendations for effective career counseling with this population are outlined, and suggestions for future research are presented.     

Dependence function for continuous bivariate densities

The notion of cross-product ratio for discrete two-way contingency table is extended to the case of continuous bivariate densities. This results in the “local dependence function” that measues the margin-free dependence between bivariate random variables. Properties and examples of the dependence function are discussed. The bivariate normal density plays a special role since it has constant dependence. Continuous bivariate densities can be constructed by specifying the dependence function along with two marginals in analogy to the construction of two-way contingency tables given marginals and patterns of interaction. The dependence function provides a partial ordering on bivariate dependence.     

Changing Spousal Roles and Their Effect on Recovery in Gamblers Anonymous: GamAnon,Social Support,Wives and Husbands

This paper examines changing spousal roles and their effects upon recovery in Gamblers Anonymous (GA). It is based upon a qualitative study designed to gage uniformity as well as variations in approaches to recovery in GA. Interviews were conducted with 39 GA members (26 men, 13 women; mean age 56.5 years). Though the study was based in the Toronto area, only 13 interviews involved participants from that region. Phone interviews were conducted with GA members from various regions of both Canada and the US. GamAnon, GA’s sister fellowship, has been designed for anyone affected seriously by someone’s gambling problem. In practice, GamAnon comprises mostly women––spouses of male GA members––who traditionally have taken a keen interest in the ways in which their husbands achieve and maintain abstinence from gambling. Changing spousal roles have led to fewer women joining GamAnon, as many opt instead to part with troubled spouses. As well, more women are attending GA than in the past, typically with husbands who are disinclined to join GamAnon. All of this has drastically altered how GA members pursue recovery. These changes and their implications are discussed.     

Sociology and the Mix Tape: A Metaphor of Creativity

Creative endeavors often resemble one another. This paper explores similarities between sociology and art based on the use of conventions and creativity. More specifically, by comparing the construction of musical mix tapes, the author draws parallels between creating sociology and mix tapes. Looking at the process of how a mix tape is created using other artists’ songs and music for a specified purpose illuminates sociology and our roles as sociologists in a new light that leaves open new possibilities.     

The Set Point Theory of Well-Being Has Serious Flaws: On the Eve of a Scientific Revolution?

Set-point theory is the main research paradigm in the field of subjective well-being (SWB). It has been extended and refined for 30 years to take in new results. The central plank of the theory is that adult set-points do not change, except temporarily in the face of major life events. There was always some ‘discordant data’, including evidence that some events are so tragic (e.g. the death of one’s child) that people never regain their set-point. It was possible to dismiss these events as ‘exceptions’ and maintain the theory. However, several new findings are emerging, which cannot be dismissed as ‘exceptions’ and which appear to require substantial revisions or replacement of set-point theory. Many of these findings are based on the German Socio-Economic Panel Survey (SOEP 1984-), which provides the longest available time series on life satisfaction. Despite its centrality, the concept of the set-point is often not precisely defined. In this paper three alternative working definitions are offered. Depending on which definition is used, it is found that over 20 years 14–30% of German panel members recorded large and apparently permanent changes in their set-points. Changes of this magnitude are not compatible with set-point theory as currently understood. The challenge for SWB researchers now is to develop a theory which can account for change as well as stability.     

A longitudinal analysis of family migration and the gender gap in earnings in the united states and great britain

This article uses longitudinal data for the United States and Great Britain to examine the impact of residential mobility and childbirth on the earnings of women, their family earnings, and the related division of earnings by gender. This project is the _ rst to compare explicitly the impact of childbirth and family migration on women’s earnings, and it extends prior cross-sectional and longitudinal studies on isolated countries by providing a direct contrast between two major industrialized nations, using comparable measures. The results indicate that families respond in similar ways in both countries to migration and childbirth. In response to both migration and childbirth, women’s earnings fall at the time of the event and recover slowly afterward, but the magnitude of the impact is roughly twice as large for childbirth as for migration. However, migration but not the birth of a child is also associated with a significant increase in total family earnings because of increased husbands’ earnings. As a result, the effect of migration on the relative earnings of wives to husbands is similar to the effect of childbirth. These results suggest that family migration should be given consideration in the literature on the gender earnings gap.     

The relation between early abuse and adult sexuality

One thousand and thirty‐two (566 non‐Asian; 466 Asian) undergraduates were assessed in a confidential laboratory setting regarding levels of physical abuse, emotional abuse, sexual abuse, neglect, and a wide range of sexuality variables. The purpose was to examine relationships between specific forms of early abuse and later adult sexuality, and to assess potential gender and ethnic differences in these associations. Independent of other forms of abuse, sexual abuse in females was significantly positively related to sexual drive and experience, range of sexual fantasies, liberal sexual attitudes, frequency of intercourse and masturbation, and likelihood of engaging in unrestricted sexual behaviors and fantasies, and was negatively related to virginity status. Among males, emotional abuse was significantly associated with poor body image and sexual dissatisfaction, independent of the other forms of abuse. There were no significant differences in associations between early abuse and sexuality between persons of Southeast Asian and European ancestry.
