Assessing capacity in the setting of self-neglect: development of a novel screening tool for decision-making capacity

Compared with older adults with disabilities and those who autonomously choose to live in squalor, self-neglect syndrome arises from a predicate state of vulnerability in frail older adults. This state of vulnerability is characteristically associated with a decline in decision-making capacity regarding the ability to care for and protect oneself. We developed the COMP Screen to evaluate vulnerable older adults to identify potential gaps in decision-making capacity using a screening tool. A total of 182 older adults were evaluated and consistent declines in cognitive ability and decision-making processes were present in this population. However, there were no significant differences between elders referred for self-neglect and matched older adults. These findings suggest that declines in decision-making processes are not uncommon in vulnerable older adults but traditional conceptualizations of decision-making capacity may be inadequate for differentiating the capacity for self-care and protection in elders who self-neglect.     

Nonparametric Identification and Estimation of Nonadditive Hedonic Models

This paper studies the identification and estimation of preferences and technologies in equilibrium hedonic models. In it, we identify nonparametric structural relationships with nonadditive heterogeneity. We determine what features of hedonic models can be identified from equilibrium observations in a single market under weak assumptions about the available information. We then consider use of additional information about structural functions and heterogeneity distributions. Separability conditions facilitate identification of consumer marginal utility and firm marginal product functions. We also consider how identification is facilitated using multimarket data.     

The role of leadership in shared mental model convergence and team performance improvement: An agent-based computational model

Research in shared mental models has immeasurably aided our understanding of effective teamwork and taskwork. However, little research has focused on the role that leaders play, if any, in influencing, developing and/or fostering shared mental models and thereby improving team performance. We developed an agent-based computational model based on McComb's theory of three-phase mental model development, where agents repeatedly share individual opinions (orientation phase), evaluate and respond to the opinions expressed by others (differentiation phase), and modify their understanding of the team based on the responses (integration phase). Leadership and team properties are represented in three experimental parameters: social network structure, heterogeneity of agents' domains of expertise, and level of their mutual interest. Participative leadership is represented by a fully connected network, while Leader–Member eXchange (LMX) is represented by a fully connected network of in-group members and several out-group members connected only to the leader. Our simulation results show that, in general, participative leadership promotes mental model convergence better than LMX. In the meantime, the team performance improvement is achieved by participative leadership only when members have both heterogeneous domains of expertise and strong mutual interest. In all other conditions, participative leadership causes the worst degradation of team performance through team development processes, while LMX is the best to minimize such team degradation. Implications and suggestions for future research are provided.     

Screening and brief intervention for alcohol problems in a university student health clinic

The purposes of this study were (1) to determine whether a university student health center (SHC) is a feasible location to introduce a campus-based screening and brief intervention (SBI) program for alcohol and (2) to determine whether the patients seen in the SHC differ in terms of the prevalence and severity of alcohol-related problems compared with students reported by emergency department programs. The authors used motivational interview techniques to counsel subjects from a convenience sample of patients waiting for medical treatment in the SHC who had screened positive with the Alcohol Use Disorders Identification Test (AUDIT). The authors interviewed patients again after 3 months. Seventy-five percent of eligible students participated. Sixty percent screened positive and received an intervention. The authors contacted 66 students (51.2%) again after 3 months. Seventy-five percent of students interviewed again after 3 months reported that SBI was helpful, 92% found the information clear, and 90% thought that the SHC was a good place to learn this information.     

Mistrusting companies, mistrusting the tobacco industry: clarifying the context of tobacco prevention efforts that focus on the tobacco industry

Campaigns to prevent adolescent smoking increasingly depict the tobacco industry as deceitful and exploitative. This study was undertaken to determine how adolescents' expectations about the trustworthiness of companies, in general, influence the pathway through which anti-tobacco industry campaigns prevent smoking. Structural equation modeling was used with survey data from 6,670 adolescents, ages 12 to 17. In the first model, statistically significant coefficients were associated with paths from mistrust of companies to mistrust of the tobacco industry, from mistrust of the tobacco industry to anti-tobacco industry attitudes, and from anti-tobacco industry attitudes to smoking. In models stratified by mistrust of companies, paths from mistrust of the tobacco industry to anti-tobacco industry attitudes and from anti-tobacco industry attitudes to smoking appeared comparable among youth with both high and low mistrust of companies. These results suggest that anti-tobacco industry campaigns resonate with youth because of youths' trust-related values and expectations.     

First Things First: a framework for successful secondary school reform

If youth development initiatives are going to focus on outcomes that we know are important in settings that we know can change these outcomes, the first outcomes should be educational, and the first setting should be school. School reform presents the most feasible, defensible, and informed opportunity for public policy to improve the life chances of children and youth in disadvantaged communities. This chapter introduces First Things First (FTF), a school reform framework grounded in research about how young people develop and how schools promote students' engagement and learning. The chapter explores four critical features of FTF that focus on students: (1) continuity of care; (2) increased instructional time; (3) high, clear, and fair standards; and (4) enriched opportunities for students. The critical features of FTF are implemented through three strategies: small learning communities, a family advocate system, and instructional improvement.     

Teaching transgender in women's studies: snarls and strategies

We moved from the San Francisco Bay Area to a small rural town in Northern California, thinking that with our years of experience in the queer and trans community we would go out to change the world. Instead, teaching Women's Studies students about transgender at Chico State changed us in ways that we never would have predicted.     

Households’ precautionary behaviors—the effects of the introduction of National Health Insurance in Taiwan

By reducing risk of large out-of-pocket medical expenses, comprehensive social health insurance may reduce households’ motivation to engage in precautionary behaviors such as saving, procurement of private insurance, and spousal labor-force participation. We use the natural experiment provided by the 1995 introduction of National Health Insurance in Taiwan to examine these effects, using pre-existing differences in access to health insurance (tied to the household head’s and spouse’s joint employment status) to identify the effects of increasing insurance coverage. We find that comprehensive health insurance has a statistically significant and large effect on household savings, but no significant effects on purchase of private accident insurance and spousal employment.

The Effects of Multiple-Tact and Receptive-Discrimination Training on the Acquisition of Intraverbal Behavior

The purpose of this study was to determine whether multiple-tact training and receptive-discrimination training could be used to teach thematically related vocal intraverbals to typically developing preschool children. Multiple-tact training involved teaching a child to name both the item and the category to which the item belonged. Receptive-discrimination training consisted of teaching a child to select a picture card in the presence of a question from the experimenter regarding the item or its category. When neither of these strategies resulted in substantial increases in intraverbal responses, a typical intraverbal training protocol using tact prompts was implemented. Six typically developing children participated in the study. A multiple-baseline design across word categories was used to evaluate the effects of the three training procedures. Results indicated that both multiple-tact and receptive-discrimination training had minimal effects on the strength of the intraverbal repertoire, whereas direct intraverbal training had a more substantial effect. The results provide some evidence of the functional independence of verbal operants, as well as the independence of listener and speaker repertoires. Receptive-discrimination and multiple-tact training may have facilitated acquisition of intraverbals; however, further research is needed to assess how these repertoires might interact with each other.
