Object Interaction and Walking: Integration of Old and New Skills in Infant Development

Manual skills such as reaching, grasping, and exploring objects appear months earlier in infancy than locomotor skills such as walking. To what extent do infants incorporate an old skill (manual actions on objects) into the development of a new skill (walking)? We video recorded 64 sessions of infants during free play in a laboratory playroom. Infants’ age (12.7–19.5 months), walking experience (0.5–10.3 months), and walking proficiency (speed, step length, etc.) varied widely. We found that the earlier developing skills of holding and exploring objects were immediately incorporated into the later developing skill of walking. Although holding incurred a reliable cost to infants’ gait patterns, holding and exploring objects in hand were relatively common activities and did not change with development. Moreover, holding objects was equally common in standing and walking. However, infants did not interact with objects indiscriminately: Object exploration was more frequent while standing than walking, and infants selectively chose lighter objects to carry and explore. Findings suggest that the earlier appearance of some skills may serve to motivate and enrich later appearing skills.     

Developing a New Approach to Case Management in Youth Mental Health: Strengths Model for Youth Case Management

Strengths Model (SM) case management has been utilized as a community based intervention with adults diagnosed with a mental illness since the 1980s. This paper describes the developmental, familial, and systemic adaptations made to the model so that it can be used with youth with mental illness. The resulting SM for Youth provides an alternative framework for providing case management to youth with mental illness which allows the youth to drive goal development and attainment by identifying and capitalizing on the youth’s strengths and resources. The model has the potential to positively impact youth mental health services by equipping supervisors and case managers with a formal model and tools, helping the case managers to feel more prepared and less stressed in their roles, and by empowering youth to engage in services that are positive and driven by their desires.     

Engaging Youth in Municipal Government: Moving Toward a Youth-Centric Practice

Youth councils are one mechanism to engage youth in community governance; yet, there is scant research to guide practice. This study examined the extent to which youth are engaged in the origin, structure, and activities of municipal youth councils. Interviews were conducted with 24 adult stakeholders involved in the operations of youth councils. Data were analyzed using thematic analysis. Results demonstrated that youth-centric practice builds upon theoretical frames of positive youth development, social justice, and civic engagement. Youth-centric practice consists of youth representation, leadership, initiative, and decision-making. Results can assist practitioners and policy makers in engaging youth in municipal government.     

Youth Program Adult Leader's Directive Assistance and Autonomy Support and Development of Adolescents’ Agency Capacity

Developing a capacity for exercising agency is an important developmental task of adolescence. Many organized youth programs provide adolescents opportunities to build their capacity to exercise agency. The researchers tested hypotheses that adult youth program leader's directive assistance and autonomy support would promote adolescents’ capacity for agency. They surveyed 441 high school adolescents and 11 adult advisors from 10 Future Farmers of America chapters twice over 2 years. Adolescents self‐reported on their capacity for agency and advisors reported on each adolescent's capacity. Directive assistance and autonomy support correlated with the capacity for agency within both time points. Only autonomy support predicted adolescents’ capacity for agency over time. Implications of leader's support for adolescents’ capacity for exercising agency are discussed.     

Family Psychoeducation for Hepatitis C Patients and Their Families: Recommendation for Clinicians

PsychoEducation Responsive to Families for Persons coping with Hepatitis C (HCV-PERF) is a multifamily psychoeducation group model designed to help patients with hepatitis C virus infection (HCV) and their families navigate the illness and improve their readiness for treatment. The purpose of this article is to provide information and recommendations for clinicians interested in using the HCV-PERF model. The article provides details of the intervention model and presents thematic categories that evolved from analysis of interviews with clinicians with experience conducting and facilitating HCV-PERF groups. Based on these findings, recommendations were developed to inform and guide the use of HCV-PERF.     

Subjectivity as “evidence”: an exploration of medication adherence in the treatment of schizophrenia using in-depth interviews

Anti-psychotic medication is considered one of the most efficaciousinterventions for the treatment of severe schizophrenia, yet ratesof adherence are notoriously and consistently low despite volumesof medical research. Scientific knowledge has failed to improvemedication adherence because it systematically rejects subjectiveexperience in conceptualizing mental illness. In this paper, thecontent of interviews with people diagnosed with schizophreniareceiving Assertive Community Treatment are interpreted from aFoucaldian perspective to illuminate how disciplinary assumptionsperpetuate power inequities and may be a barrier to adequateresearch generation and effective treatments. Implications for futureresearch methodology and clinical approaches are discussed.     

Jackknife and Analytical Bias Reduction for Nonlinear Panel Models

Fixed effects estimators of panel models can be severely biased because of the well‐known incidental parameters problem. We show that this bias can be reduced by using a panel jackknife or an analytical bias correction motivated by large T. We give bias corrections for averages over the fixed effects, as well as model parameters. We find large bias reductions from using these approaches in examples. We consider asymptotics where T grows with n, as an approximation to the properties of the estimators in econometric applications. We show that if T grows at the same rate as n, the fixed effects estimator is asymptotically biased, so that asymptotic confidence intervals are incorrect, but that they are correct for the panel jackknife. We show T growing faster than n^1/3 suffices for correctness of the analytic correction, a property we also conjecture for the jackknife.     

Are mainstream support services meeting the needs of sexual minority women with breast cancer? An exploration of the perspectives and experiences of users of an online support forum

We conducted an inductive content analysis of messages posted to the lesbian-specific discussion board forum found on breastcancer.org for the purpose of examining sexual minority women's experiences of and perspectives on mainstream cancer support services. Our analysis indicated that currently available support services might not be adequately addressing sexual minority women's unique needs. Individuals posting to the lesbian-specific forum reported the presence of homophobia, heterosexual bias, and feelings of exclusion in mainstream breast cancer support services. In contrast, forum users generally perceived nonspecific cancer support groups to be beneficial, yet the majority preferred lesbian-specific support.     

Approximation and information topologies

In this paper approximation properties of finite dimensional parametric models are described in terms of an information metric: the Hellinger distance. Under conditions on the parametric family given solely in terms of a comparison of the Hellinger distance with the parameter metric, optimal rates of convergence are described. It is also shown how to use these conditions on the parametric family to determine whether consistent estimation is possible. We give applications of the theorems to regular and non-regular parametric families, and to nonlinear regression.
