The puzzle of the self-torturer

I've profited from discussions with Alan Nelson, David Erikson, Yoram Gutgelt, Tony Martin, members of a seminar at New York University, and, especially, Kit Fine.     

The Gender Difference in the Association Between Early Onset of Drinking and Problem Drinking Between the U.S. and Japan

Using comparable survey data from the GENACIS Project, collected from representative samples of people aged 20 to 70 years old in the U.S. (n = 2,598) and Japan (n = 1,734), this study examined, across these two diverse societies, the gender difference in the association between the early onset of drinking and the development of drinking problems. The results of this study suggest that there does not appear to be a cross-national causal relationship between the early onset of drinking and problem drinking because of significant country and gender variations in this association and because there is no association found among Japanese females. As hypothesized, the early onset of drinking predicted problem drinking among males more strongly than among females in both countries.     

Caregivers’ beliefs about dementia: findings from the IDEAL study

Abstract

Objective: Informal caregivers of people with dementia develop their own beliefs about the condition, referred to as Dementia Representations (DRs), as they try to make sense of the changes they are observing. The first aim of this study was to provide a profile of the types of DRs held by caregivers. The second aim was to examine the impact of caregivers’ DRs on their well-being, satisfaction with life (SwL) and caregiving stress.

Methods: Participants were 1264 informal caregivers of people in the mild-to-moderate stages of dementia from time-point 1 of the IDEAL cohort study.

Measures: DRs were measured using questionnaire items covering: Identity, Cause, Control, and Timeline.

Results: Almost half (49.2%) of caregivers used a diagnostic term to describe the person’s condition, although 93.4% of caregivers stated they were aware of the diagnosis. Higher well-being, SwL, and lower caregiving stress were associated with the use of an identity term relating to specific symptoms of dementia, attributing the cause to ageing or not knowing the cause, and believing the condition would stay the same. Lower well-being, SwL, and higher caregiving stress were associated with believing there was little that could be done to control the effects of the condition.

Conclusion: Healthcare professionals should assess and gain an understanding of caregivers’ DRs in order to provide more tailored information and support.     

describing sexual behavior in the era of the internet: a typology for empirical research

This article uses the Mobile Youth Survey (MYS) to quantitatively evaluate Elijah Anderson's seminal theory of African-American youth in Philadelphia, the Code of the Street. Using longitudinal data and Structural Equation Modeling, we identify characteristics that lead underclass youth to adopt or to reject a “street code” mentality. Like other studies of Anderson's Code of the Streets, we examine family and peer relationships, neighborhood control and stability, victimization and negative emotional reactions as predictors of adolescents' street code orientation. At the same time, we introduce for the first time, hopelessness, defined as a state of mind in which individuals have a negative perception of their future, into the intellectual and social equation. Results show that hopelessness plays an instrumental role in adopting street code beliefs. Specifically, adolescents reporting greater hopelessness in 2004 were more likely to identify with the street code in 2005; by extension, adolescents who identified with the street code in 2005 were also more involved in violence.     

Influences of APOE ε4 and expertise on performance of older pilots

Little is known about how APOE ε4-related differences in cognitive performance translate to real-life performance, where training and experience may help to sustain performance. We investigated the influences of APOE ε4 status, expertise (FAA pilot proficiency ratings), and their interaction on longitudinal flight simulator performance. Over a 2-year period, 139 pilots aged 42-69 years were tested annually. APOE ε4 carriers had lower memory performance than noncarriers (p = .019). APOE interacted with Expertise (p = .036), such that the beneficial influence of expertise (p = .013) on longitudinal flight simulator performance was more pronounced for ε4 carriers. Results suggest that relevant training and activity may help sustain middle-aged and older adults' real-world performance, especially among APOE ε4 carriers.
