Evaluation of HIV/AIDS peer education projects in Zambia

This 1998 evaluation assessed the peer education programmes of HIV/AIDS projects run by four non-governmental organisations. A mini-case study approach was used and analysis was based on cross-case itemistic variables. The projects were assessed only in terms of immediate developmental outcomes to target groups rather than on long-term impact. The study concluded the following: (1) The projects had raised community awareness of HIV/AIDS; (2) Basic knowledge of HIV/AIDS was for the most part accurate; (3) There was anecdotal evidence of behavioural changes in terms of partner-reduction as reported by the projects, though the evidence was sometimes conflicting; and (4) There was evidence that certain traditional practices, which contributed to the spread of the virus (e.g. sexual cleansing and scarification), were becoming modified over time. The programmes were also instrumental in protecting human rights and enabling people living with HIV/AIDS to maintain human dignity.     

Observed and parent‐reported conscience in childhood: Relations with bullying involvement in early primary school

This exploratory study aimed to examine which components of early childhood conscience predicted bullying involvement around school entry. In the population‐based Generation R Study, teacher reports of bullying involvement and parent reports of conscience were available for 3,244 children (M age = 6.7 years). Higher levels of overall conscience predicted lower bullying perpetration scores, independently of intelligence quotient, temperamental traits and sociodemographic characteristics. Particularly, the subscales guilt, confession, and internalized conduct, and to a lesser extent empathy, predicted bullying perpetration. Conscience was not related to victimization. Similar results were found using observations during so‐called ‘cheating games’ (subsample N = 450 children). Findings suggest that improving children's understanding of moral standards and norms may be a potential target for bullying intervention programs in early primary school.     

Psychological Mediators of the Sport Injury—Perceived Risk Relationship

Drawing upon both heuristic‐ and threat‐based approaches, we sought to examine whether perceived similarity with injury‐prone people and perceived control over injury occurrence would directly contribute to perceived risk and whether these variables would mediate the previous injury–perceived risk relationship. Judokas (n = 207) reported the number of injuries experienced in the past year and then completed measures of perceived similarity, perceived control, and injury risk perception. Analyses revealed that perceived similarity and perceived control directly contributed to perceived risk of injury; only perceived similarity acted as a partial mediator of the injury–perceived risk relationship. These findings are discussed in relation to the potential influence of the sport context, which universally involves the acceptance of a high risk of injury.     

The victim–offender overlap in late adulthood

This study contributes to the general knowledge of the victim–offender overlap by determining whether the phenomenon exists among older adults and whether known correlates of crime and victimization explain the relationship. Cross-sectional survey data from telephone interviews conducted with individuals 60 years and older (N = 2,000) residing in Arizona and Florida are used to estimate confirmatory factor models for both victimization and criminal offending. The results from a series of multivariate regression models show that victimization is associated with criminal offending. While factors such as low self-control, depression, and spending time in commercial drinking establishments partially attenuate the victimization–crime link, the statistically significant relationship persists in a multivariate context. Further testing indicates that the observed findings are robust across measurement and modeling strategies. Coupled with prior research, the results support the argument that the victim–offender overlap exists (and is difficult to explain) over the life course.     

“Double-dose” English as a strategy for improving adolescent literacy: Total effect and mediated effect through classroom peer ability change

“Double-dose” coursework has become an increasingly popular strategy to assist low-performing students succeed in academic coursework. Chicago implemented a “double-dose” English policy in 2003. This policy not only provided additional instructional time to struggling readers, but also intensified skill-based sorting in English classes. I use policy-induced variation to infer the policy effect on students’ reading achievement and the effect mediated by classroom peer ability change. Results show very weak, but positive effects of taking double-dose English for students with average skills. However, potential benefits of doubled instructional time are likely to be offset by negative effects of declines in classroom peer ability. Students with very weak skills experienced minimal change in classroom peer ability, and two-period coursework is likely to benefit these students.     

Traversing gender,sexual orientation,and race-ethnicity: Sexual victimization in a population-based sample of older adults

This research examined the intersectionality of gender, sexual orientation, and race-ethnicity, and its impact on lifetime sexual victimization among a population-based sample of older adults. Data for this study came from the 2011–2014 waves of the Behavioral Risk Factor Surveillance System. The final sample to be used for analysis included 8.862 individuals ages 50 years and over to examine whether and to what extent lesbian, gay, and bisexual older adults differ from heterosexual older adults in experiencing lifetime sexual victimization, and whether the effect of sexual orientation on experiencing lifetime sexual victimization differs across racial-ethnic groups. Logistic regression analysis revealed that lesbian women were 2.59 times more likely and bisexual women 2.15 times more likely both relative to heterosexual women to experience lifetime sexual victimization. When examining whether race-ethnicity imparts additional risk, the findings revealed that non-White heterosexual individuals were 29.6% less likely relative to White heterosexual individuals to experience lifetime sexual victimization, while non-White women, generally, were 2.29 times more likely relative to White men to experience lifetime sexual victimization. Our findings affirm the importance of the intersectionality of sexual orientation and gender when examining lifetime sexual victimization of older adults, adding to the emerging body of research that examines the complexities of older adult lives from multifaceted perspectives.     

Rank and response: A field experiment on peer information and water use behavior

Perception of peer rank, or how we perform relative to our peers, can be a powerful motivator. While research exists on the effect of social information on decision making, there is less work on how ranked comparisons with our peers influence our behavior. This paper outlines a field experiment conducted with 3896 households in Castro Valley, California, which uses household mailers with various forms of social information and peer rank messaging to motivate water conservation. The experiment tests the effect of a visible peer rank on water use, and how the competitive framing of rank information influences behavioral response. The results show that households with relatively low or high water use in the pre-treatment period responded differently to how rank information was framed. I find that a neutrally-framed peer rank caused a small “boomerang effect” (i.e., an increase in average water use) for low water use households, but this effect was eliminated by competitive framing. At the same time, a competitively-framed peer rank demotivated high water use households, increasing their average water use over the full period of the experiment. This result is supported by evidence that the competitive frame on rank information increased water use for households who ranked “last” in the peer group – a detrimental “last place effect” from competitively-framed rankings.     

Enforcing cooperation in public goods games: Is one punisher enough?

We experimentally investigate a finitely repeated public goods game setting where, in each round, access to sanctioning power is exclusively awarded to one single player per group. We show that our central ‘Top Contributors as Punishers’ institution – a mechanism by which a player needs to be the highest contributor in her group in order to earn the right to sanction others – is extremely effective in raising cooperation and welfare due to turnover in the top contributor role and to top contributors’ willingness to substantially sanction others. Our findings yield implications for the design of mechanisms intended to foster cooperation in social dilemma environments.     

Self‐Esteem,the Fear of Crime,and the Decision to Protect Oneself From Victimization

This research extends prior work that examines self‐esteem as an outcome of protective behaviors against crime victimization by focusing instead on the moderating influence of self‐esteem on the relationship between the fear of crime and the decision to protect oneself from victimization. The fear of crime is conceptualized as two separate components (fear of victimization and perceived risk) in accordance with prior work. Self‐esteem is conceptualized as three separate components (worth, efficacy, and authenticity), and measured with a recently designed instrument for capturing each aspect of self‐esteem separately. Data are collected through surveys of a population at high risk for victimization (undergraduate college students). Logistic regression analyses demonstrate that self‐esteem does play a role for deciding whether to engage in protective behaviors, and that the specific components of self‐esteem moderate defensive behavioral outcomes differently. Specifically, the self‐worth, self‐efficacy, and authenticity components of self‐esteem influence the decision to carry protection, but not the decision to take a self‐defense class. Implications for both the fear of crime and self‐esteem literatures are addressed.
