Prevalence and Correlates of Sex Exchange Among a Nationally Representative Sample of Adolescents and Young Adults

The present study examines prevalence and correlates of exchanging sex for drugs, money, food shelter, or other favors (sex exchange) among a nationally representative sample of youth and young adults. Adolescents and young adults (n = 11,620, 53% female, 47% male) from the National Longitudinal Study of Adolescent Health were used for the current sample. Participants completed in-home interviews at both waves. Results revealed that sex exchange was reported by 4.9% (n = 569) of the population in wave 2 or wave 3, and 4.6% (n = 26) of those who exchanged sex did so at both waves. More males reported exchanging sex than females (n = 332 versus n = 237). Respondents who reported child sexual abuse were more likely to exchange sex (95% CI 2.51–4.28, p < .05) than respondents who reported any other form of child abuse. Both males and females who engaged in sex exchange were at greater risk for sexually transmitted infections; however, the odds of ever exchanging sex were highest among males who ever had gonorrhea (OR = 6.2; 95% CI 3.75–10.3). Although sex exchange has been studied extensively among homeless and runaway youth, the current study reveals sex exchange also occurs in the general population.     

Adding Insult to Injury: Sex,Sexual Orientation,and Juror Decision-Making in a Case of Intimate Partner Violence

Societal definitions of intimate partner violence (IPV) are highly gendered and heteronormative, resulting in dissonance regarding cases of same-sex IPV. This study explored perceptions of IPV when the context of the case is inconsistent with societal norms regarding sex and sexuality. Mock jurors read a vignette describing a case of alleged IPV in which the sex and sexual orientation of the defendant were manipulated. Participants (N = 415) rendered a verdict and provided ratings of the defendant, victim, and case. Results suggest participants were more confident in a guilty verdict when the defendant was male, compared to female. Further, male defendants were perceived as more morally responsible, but only when the victim was female. Perceptions regarding the crime suggest violence perpetrated by a man against a woman is viewed more adversely than any other condition. Data are discussed in terms of implications for legal decision-makers and public policy.     

Behaviour change strategies for problem gambling: an analysis of online posts

Reducing or quitting problematic gambling often requires implementing a variety of behaviour change strategies, but there is limited evidence regarding the breadth of specific strategies that gamblers use to control or limit gambling behaviours. This study aimed to identify the range of change strategies reported by gamblers in a naturalistic setting (i.e. two online forums for problem gambling). A total of 2937 change strategies were extracted from online posts (N = 1370). Content analysis identified 27 discrete change strategies that were pre-decisional (i.e. barriers – behavioural and psychological, decisional balance, realization – behaviour and cognitions, set reasons to change, seek knowledge and information, self-assessment), pre-actional (i.e. action planning, commitment, goal setting), actional (i.e. alternative activity, behavioural substitution, avoidance – abstinence, environment and financial, consumption control, maintain readiness, reinforcement, urge management, cognitive restructuring, seek inspiration, self-monitoring and spiritual) and multi-phased (i.e. external support, social support and well-being). This study suggests the breadth and depth of change strategies are far more complex than previously reported. Future research with a broader population needs to determine which change strategies are most effective for those experiencing different levels of gambling problems.     

Social Work Student Self-Care and Academic Stress

The purpose of the present study was to investigate the relationship between self-care and academic stress in the hope that training social work students to practice self-care will start them on the right path to academic success and career longevity. The study surveyed 90 BASW and MSW students using the Academic Stress Scale. Students who practiced daily self-care had lower academic stress. In addition, with each year of progression through the program, students experienced minimally less academic stress. The type of self-care practiced was not a factor. Social work programs can be encouraged to teach self-care. Self-care theory and domains are also reviewed. More studies are needed to examine other factors that might reduce academic stress.     

A permutation test for the spread of three-dimensional rotation data

The permutation test is a nonparametric test that can be used to compare measures of spread for two data sets, but is yet to be explored in the context of three-dimensional rotation data. A permutation test for such data is developed and the statistical power of this test is considered under various conditions. The test is then used in a brief application comparing movement around the calcaneocuboid joint for a human, chimpanzee, and baboon.     

Paid family leave: supporting work attachment among lower income mothers

ABSTRACT

Around the time of childbirth, low-income families are at particular economic risk for reasons including mothers’ relatively high levels of separation from work. Lower wage jobs typically come with minimal paid leave that can be used at childbirth. Paid Family Leave (PFL) programs provide partially subsidized wages to new parents. Quantitative research links PFL with greater post-birth work attachment among mothers, including lower wage mothers. This qualitative study sought to explore factors that facilitate – and inhibit – lower income mothers’ returns to work following childbirth and the role of PFL programs. Seventy-one percent of the 75 mothers in the study returned to work. They cited their need for income, desire for financial independence, preference for combining work and caregiving, supportive workplace practices, family help, and accessible and trustworthy child care. They described ways PFL supported employment, especially for single mothers and those with the fewest family resources. Twenty-nine percent of the mothers left work after childbirth for reasons including child care costs, a desire (or need) to remain home rather than work, low job quality, lack of job protection, and PFL program limitations. The findings suggest future research directions and pathways for service providers and others to support these families.     

The Perception and Parameters of Intentional Voice Manipulation

Evidence suggests that people can manipulate their vocal intonations to convey a host of emotional, trait, and situational images. We asked 40 participants (20 men and 20 women) to intentionally manipulate the sound of their voices in order to portray four traits: attractiveness, confidence, dominance, and intelligence to compare these samples to their normal speech. We then asked independent raters of the same- and opposite-sex to assess the degree to which each voice sample projected the given trait. Women’s manipulated voices were judged as sounding more attractive than their normal voices, but this was not the case for men. In contrast, men’s manipulated voices were rated by women as sounding more confident than their normal speech, but this did not hold true for women’s voices. Further, women were able to manipulate their voices to sound just as dominant as the men’s manipulated voices, and both sexes were able to modify their voices to sound more intelligent than their normal voice. We also assessed all voice samples objectively using spectrogram analyses and several vocal patterns emerged for each trait; among them we found that when trying to sound sexy/attractive, both sexes slowed their speech and women lowered their pitch and had greater vocal hoarseness. Both sexes raised their pitch and spoke louder to sound dominant and women had less vocal hoarseness. These findings are discussed using an evolutionary perspective and implicate voice modification as an important, deliberate aspect of communication, especially in the realm of mate selection and competition.     

Optimal Deterrence with Legal Defense Expenditure

Legal defense expenditure by honest and dishonest accused can increase or reduce the amount of crime, and deterrence can decrease when punishment is increased. Unregulated expenditure of innocent and guilty defendants is inefficient whether or not there is a direct social harm from type I and II errors. The circumstances in which the optimal fine bankrupts convicted dishonest or honest defendants, regulation to limit defense expenditure and a tax-financed public defender system are also investigated.     

Reliability and validity of responses to submaximal all-extremity semirecumbent exercise in older adults

Although popular in clinical settings, little is known about the utility of all-extremity semirecumbent exercise machines for research. Twenty-one community-dwelling older adults performed two exercise trials (three 4-min stages at increasing workloads) to evaluate the reliability and validity of exercise responses to submaximal all-extremity semirecumbent exercise (BioStep). Exercise responses were measured directly (Cosmed K4b2) and indirectly through software on the BioStep. Test-retest reliability (ICC2,1) was moderate to high across all three stages for directly measured METs (.92, .87, and .88) and HR (.91, .83, and .86). Concurrent criterion validity between the K4b2 and BioStep MET values was moderate to very good across the three stages on both Day 1 (r = .86, .71, and .83) and Day 2 (r = .73, .87, and .72). All-extremity semirecumbent submaximal exercise elicited reliable and valid responses in our sample of older adults and thus can be considered a viable exercise mode.
