Exploring the Role of Working Memory in Dynamic Social Cue Decoding Using Dual Task Methodology

Decoding nonverbal social cues involves skills such as understanding emotions and discerning kin relationships. Social cue decoding has been described as an automatic process which does not tax cognitive resources. However, clinical deficits in social decoding are often interpreted in terms of deficits in attention and working memory. Two experiments are described which used dual task methodology to investigate the role of working memory in dynamic social cue decoding tasks: the Interpersonal Perception Task (IPT, Experiment 1) and the Profile of Nonverbal Sensitivity (PONS, Experiment 2). Results revealed that decoding social cues from the IPT did not require working memory resources, while social perception in the PONS made heavy demands on working memory. Implications for theoretical interpretation of these tasks and their use in clinical populations are discussed.

From behind the shadows: a profile of the sexual abuse of older men residing in nursing homes

Previous research on the sexual abuse of older adults has revealed few cases of the sexual abuse of older men. The first national study of the sexual abuse of vulnerable adults in facilities, reported in this article, collected data on alleged, investigated, and substantiated cases of sexual abuse. This study revealed 26 cases reported and screened in for investigation concerning the alleged sexual abuse of older men (aged 50 and older) residing in nursing homes. Cases occurred in five states within a six month time period. Of these cases, six were confirmed upon investigation by Adult Protective Services or other regulatory agencies. Victims tended to be predominantly white males with cognitive and physical deficits that limited their ability for self care. The most typical sexual abuse alleged and substantiated was fondling. Residents were more often substantiated as the abuser than other perpetrators. Sexual abuse of older men in nursing homes crosses traditional gender, cultural, and role boundaries for both victims and perpetrators.     

International Student Mobility and Tertiary Education Capacity in Africa

In Africa, 5.8 per cent of enrolled tertiary students go outside their homelands for tertiary study. No other world region has this high a share of outbound student mobility. In this study, I examined why African countries have larger student outflows than other regions and, in particular, I considered the importance of tertiary education capacity in the region for student mobility. I evaluated the determinants of student outflows from African countries for three different measures: the total number of tertiary students abroad, the percentage of the tertiary age cohort studying abroad and the percentage of total enrolled students abroad. In addition to showing that country rankings differ on these mobility measures, the findings indicate that their determinants also differ. The study premise was that student outflows should be lower from countries that have a greater supply of tertiary training capacity and that thesis received strong support in models that estimated the percentage of total enrolled students abroad. In models for that outcome, student outflows were also larger if countries had high tertiary demand and populations under 2 million. The findings for models that estimated total numbers abroad and share of the tertiary cohort abroad were similar after controlling for interactions between tertiary education supply and GDP per capita. In addition, population size and per capita GDP were stronger correlates of student mobility in those models, which suggests that it is more difficult for education supply and demand measures to account for student outflows when crude outflow measures are used. I concluded that strengthening tertiary education supply at home would be a cost‐effective way for African governments to increase their human capital and reduce brain drain losses.     

Effects and Costs of Tracing Strategies on Nonresponse Bias in a Survey of Workers with Low-Back Injury

Declining rates of participation are an increasing challengefor studies that involve telephone surveys. This study examinedthe costs of a telephone survey methodology that used increasinglyintensive tracing methods to track a pool of claimants who hadsustained occupational back injuries. It also compared the respondentsample to people who refused the survey and/or were not locatedor contacted. 3,181 claimants were drawn from a database maintainedby the Missouri Division of Workers’ Compensation (DWC)and 1,475 completed a telephone interview. The DWC databaseprovided data reflecting monetary and disability outcomes forall potential participants; telephone interviews provided additionalself-reported data. More intensive tracing strategies improvedthe representativeness of the sample, yielding more women andminority participants. Relative to less intensive techniques,advanced tracing efforts located people whose DWC records weremore similar to claimants not located. While the hands-on tracingefforts reduced the apparent bias of the respondent sample,costs increased as tracing strategies intensified – over$98,000 was spent to trace 1,027 claimants who were never locatedor contacted. The results suggest some guidelines that may facilitatedecision-making for researchers and funders who must balancethe trade-off between costs and nonresponse bias when planningsurveys.     

Evaluating child welfare training in public agencies: status and prospects

Although staff training in public child welfare agencies is thought to be a critical component of effective practice, little is known about the delivery and effectiveness of training interventions. Few evaluations are published in the literature and it is uncertain how much evaluation activity is being conducted and utilized. This study collected data from 48 public child welfare agencies in the United States regarding the conduct of training evaluation and the utilization of training data. The data are discussed within the context of planning the next steps for public agencies’ efforts in training evaluation.     

'If you could change one thing...' What community-based researchers wish they could have done differently

Community-based research (CBR) is rapidly gaining recognitionsas an important tool in addressing complex environmental, healthand social problems. CBR attempts to marry community developmentwith knowledge generation. However, little is known about theCanadian CBR context. This paper reports on the analysis ofan element within a web-based survey to investigate the statusof CBR in Canada. The survey included 25 questions. This paperfocuses on responses to one open-ended question (Q20): ‘Ifthere was one thing you could change about [your last CBR] project,what would it be?’ A content analysis approach guidedanalysis and responses were coded into main theme and subthemes.Our collective reflections offer other CBR practitioners anopportunity to more effectively plan future partnerships.     

Behavior change and the freshman 15: tracking physical activity and dietary patterns in 1st-year university women

OBJECTIVE AND PARTICIPANTS: The authors assessed the stability of diet and physical activity and their relationship to weight changes in first-year university women. METHODS: They collected anthropometric and body composition data from 101 resident women at the beginning of their first year of college and again at 12 months. The authors obtained physical activity and dietary logs 4 times throughout the year. RESULTS: Caloric intake decreased over 12 months in all participants (p = .01). There was little change in physical activity in participants who lost weight (p = .73, d = .18). Those who gained weight experienced a trend toward decreased physical activity (p = .13, d = .38). A significant Time X Group interaction on physical activity (p = .04) suggests that physical activity patterns differed substantially between individuals who gained weight and those who lost weight. CONCLUSIONS: Reduction in physical activity appears to be the defining characteristic in freshman weight gain.     

Non-estrogen-based treatments for menopausal symptoms

The British Menopause Society Council is committed to provide up-to-date authoritative reviews to aid health professionals to inform and advise women about key issues in postreproductive health. This guidance refers to non-estrogen-based treatments for menopausal symptoms, such as hot flushes, symptoms of urogenital atrophy and lack of sexual desire. Treatment of choice should be based on up to-date information and targeted to individual women's needs. Non-hormonal strategies may be useful for women with estrogen-dependent disease such as breast cancer.     

Accumulation of deicing salts in soils in an urban environment

Examining rates of deicing salt accumulation and leaching in urban soils is important for understanding the distribution and movement of salt in the environment. We examined autumn concentrations of deicing salts in soils in a moderately dense urban landscape in eastern New York State. The study area contrasted to the isolated, rural highways examined in previous studies. While NaCl was the most abundantly applied salt, Mg²⁺ (apparently from MgCl₂, a secondary deicing salt) was the most abundant salt cation in soils. Moderate Na⁺ levels, and equivalent concentrations at depth and in surface samples, indicate that leaching of Na⁺ is rapid in this system. Leaching may ameliorate toxicity for land plants but accelerate inputs to aquatic systems. In contrast to rural highway studies, where salt levels declined rapidly with distance to pavement, Na⁺ remained elevated at the maximum distance measured. Airborne salt dispersal and dense networks of pavement likely contribute to widespread elevated salt levels. This semi-urban setting had salt levels high enough to be toxic to terrestrial plants and soil protozoa. Even moderate levels of development can have dramatic effects on salt inputs into soils and aquatic systems.

Disadvantagement-related correlates of career optimism among college and university students with disabilities

This paper describes research regarding factors predicting career optimism for a group of postsecondary students with disabilities (N = 208) who were enrolled in seven colleges and universities in four states. Career optimism was defined as a student's self-confidence regarding his or her ability to choose, maintain, and advance in an appropriate career. The proposed model incorporated variables related to employment discrimination and disincentives such as perceived impact of disability on one's education and quality of life, racial/ethnic status, gender, and presence of disability benefits. Results indicated that two aspects of "disadvantagement," specifically severity of perceived impact of disability and racial/ethnic status, were significant predictors of career optimism. Implications of the findings were discussed in terms of informational interventions, curricula, development of self-advocacy and self-determination, and research topics.
