The association between sensation seeking and e-cigarette use in Texas young adults: A cross-sectional study

Objective: To examine the associations between sensation seeking and ever and current e-cigarette use in Texas young adults (18–29 years old). Current cigarette use was examined as a potential effect modifier of the associations. Participants: Participants included college students enrolled in four-year and two-year colleges in four metropolitan areas in Texas (n = 5,418) who completed the survey between November 2014 and February 2015. Methods: This cross-sectional study utilized mixed effects logistic regression to determine the associations between mean sensation seeking scores and ever and current e-cigarette use after controlling for covariates. Results: After controlling for covariates, significant associations between sensation seeking and both ever and current e-cigarette use were observed; however, these associations were significant for noncurrent smokers only (adjusted odds rations [AOR] = 1.55, 95% confidence interval (CI) = 1.39, 1.73; AOR = 1.82, 95% CI = 1.54, 2.15, respectively). Conclusions: Sensation seeking is an important factor in identifying college students who may be at increased risk for e-cigarette use behaviors.     

A variability taxonomy to support automation decision-making for manufacturing processes

Abstract

Although many manual operations have been replaced by automation in the manufacturing domain in various industries, skilled operators still carry out critical manual tasks such as final assembly. The business case for automation in these areas is difficult to justify due to increased complexity and costs arising out of process variabilities associated with those tasks. The lack of understanding of process variability in automation design means that industrial automation often does not realize the full benefits at the first attempt, resulting in the need to spend additional resource and time, to fully realize the potential. This article describes a taxonomy of variability when considering the automation of manufacturing processes. Three industrial case studies were analyzed to develop the proposed taxonomy. The results obtained from the taxonomy are discussed with a further case study to demonstrate its value in supporting automation decision-making.     

Exploring an HIV paradox: an ethnography of sexual minority women injectors

HIV risk and infection are markedly increased among sexual minority women injectors compared to other injecting drug users. Our ethnographic exploration of this well-documented but poorly understood phenomenon included 270 interviews and over 350 field observations with 65 sexual minority women injectors in New York City and Boston. We discuss findings in relation to four preliminary hypotheses. Neither the presence of gay or bisexual men in risk networks, nor a sense of invulnerability due to lesbian (or other sexual minority) identity seem to be plausible explanations of increased HIV among sexual minority women injectors. However, multiple marginalization was found to be pervasive and to have severe consequences that can be traced to increased HIV risk for many women in the study.     

Prejudice as Lifeform*

Sociological research on racial prejudice has generated consistent and reliable empirical findings on the social determinants of prejudice, but comprehensive theoretical explanations of the social forces that promote prejudice tend to be controversial. Two such theoretical perspectives are examined and then compared for their ability to explain prejudice; namely Durkheim's theory of cognition and the neoevolutionist approach to sociocultural modernization and ontogenetic maturation. An attempt also is made to merge the interactionist and evolutionist arguments for the purpose of developing a comprehensive explanation of prejudice.     

Sex differences in morbidity and mortality

Women have worse self-rated health and more hospitalization episodes than men from early adolescence to late middle age, but are less likely to die at each age. We use 14 years of data from the U.S. National Health Interview Survey to examine this paradox. Our results indicate that the difference in self-assessed health between women and men can be entirely explained by differences in the distribution of the chronic conditions they face. This is not true, however, for hospital episodes and mortality. Men with several smoking-related conditions--including cardiovascular disease and certain lung disorders--are more likely to experience hospital episodes and to die than women who suffer from the same chronic conditions, implying that men may experience more-severe forms of these conditions. While some of the difference in mortality can be explained by differences in the distribution of chronic conditions, an equally large share can be attributed to the larger adverse effects of these conditions on male mortality. The greater effects of smoking-related conditions on men's health may be due to their higher rates of smoking throughout their lives.     

Internalized homophobia and depression in lesbian women: The protective role of pride

This study sought to examine the association between internalized homophobia and depressive symptoms in lesbian women, and establish whether such a relationship was mediated by collective self-esteem, self-esteem, and self-disclosure. Participants were 225 self-identified lesbian women in the community. Structural equation modeling was used to demonstrate that an underlying construct, labeled pride, reflected participants’ levels of self-esteem, collective self-esteem, and self-disclosure. Internalized homophobia was moderately and negatively predictive of pride, and pride was strongly and negatively predictive of depression. Results highlight the potentially protective role of pride in the prevention of depression among lesbian women.
