The Semantically Reciprocating Robot: Adult Influences on Children's Early Conversational Skills

Two-year-old children's conversational replies were observed in two social contexts: (a) with a partner who consistently responded to each of their utterances by semantically reciprocating and commenting briefly on their topic; or (b) with a partner who also consistently replied to each of their utterances but did not semantically reciprocate their topic. Children were significantly more likely to reply to a partner who maintained their topic. Given that a child replied, the verbal responses in the semantic reciprocation group were also more likely to have a topic-comment structure characteristic of more advanced conversational skills. These experimental data confirm previous correlational evidence suggesting that children are sensitive to semantic reciprocation during the early stages of verbal communicative development, and they support recent arguments suggesting that the adult's use of expansions scaffolds the child's tendency to use predicative, topic-comment replies…and perhaps advances the child's understanding of the adult partner as an attentional/intentional mental agent.     

Developing geriatric social work competencies for field education

Preparing social workers to effectively practice with the growing older population requires the identification of geriatric competencies for the profession. The John A. Hartford Geriatric Social Work Initiative provided the impetus and direction for a national strategy to improve the quality of preparation of geriatric social workers. The Geriatric Social Work Practicum Partnership Program (PPP) is the project with the Hartford Initiative that emphasizes field education. The Geriatric Social Work Education Consortium (GSWEC), one of the PPP programs, initiated the development of competencies for work with older adults. GSWEC utilized Geriatric Social Work White Papers and the pioneering work of the Council on Social Work Education's (CSWE) Strengthening Aging and Gerontology Education for Social Work's (SAGE-SW) comprehensive competency list as well as conducted focus groups locally to delineate key competencies for field education. The Coordinating Center for the PPP, located at the New York Academy of Medicine, led in collaboratively developing knowledge based skill competencies for geriatric social work across all 6 demonstration sites (11 universities). The competencies adopted across sites include skills in the following five major domains: values and ethics; assessment (individuals and families, aging services, programs and policies); practice and interventions (theory and knowledge in practice, individual and family, aging services, programs and practice) interdisciplinary collaboration; and evaluation and research. The identified competencies have proven effective in evaluating students (n = 190) pre- and post PPP field education. The implications for further development of competency driven education for geriatric social work are discussed.     

EVVMA and cusum control charts in the presence of correlation

The statistical properties of control charts are usually evaluated under the assumption that the observations from the process are independent. For many processes however, observations which are closely spaced in time will be correlated. This paper considers EWMA and CUSUM control charts for the process mean when the observations are from an AR(1) process with additional random error. This simple model may be a reasonable model for many processes encountered in practice. The ARL and steady state ARL of the EWMA and CUSUM charts are evaluated numerically using an integral equation approach and a Markov chain approach. The numerical results show that correlation can have a significant effect on the properties of these charts. Tables are given to aid in the design of these charts when the observations follow the assumed model.     

Adolescents in residential treatment: The prevalence of ACEs,substance use and justice involvement

Abstract

Although associations between developmental trauma, juvenile justice involvement and youth substance use have been previously reported in the published literature, the interconnection among these three factors has not been adequately studied. This article describes the interconnection among these three factors and calls for greater attention to the role of adverse childhood experiences (ACEs) in the diagnosis and treatment of youth who present with histories of substance use and/or offending behavior. Pilot data are presented that show high rates of self-reported trauma exposure, substance use history, justice involvement, and mental health problems in a sample of adolescents in residential treatment. The data point to the need for residential treatment centers to consider trauma histories in developing treatment plans for youth with current and prior substance use and offending behavior.     

What are the Risk Factors for Antisocial Behavior Among Low‐income Youth in CapeTown?

Research in high‐income countries has identified an array of risk factors for youth antisocial behavior. However, in low‐ and middle‐income countries, despite higher prevalence of offending and antisocial behavior, there is a paucity of prospective, longitudinal evidence examining predictors. South Africa is a middle‐income country with high rates of violence and crime, and a unique social context, characterized by striking income and gender inequality, and increasing number of children orphaned by AIDS. We tested predictors of antisocial behavior at community, family, and individual levels over four years. One thousand and twenty five adolescents from poor, urban South African settlements were assessed in 2005 (50 percent female; M = 13.4 years) and followed up in 2009. The sample analyzed consisted of the 723 youth (71 percent) assessed at both time points. We employed sociodemographic questionnaires and standardized scales. Validity of our antisocial behavior measure was supported by cross‐sectional associations with well‐evidenced concomitants of youth antisocial behavior, including drug taking and truancy. Regression analysis indicated that male gender and experience of community violence, but not poverty or abuse, predicted antisocial behavior. Despite many South African youth experiencing abuse and poverty at the family level, our findings suggest that high levels of violence in communities may be a more important factor contributing to the development of antisocial behavior, particularly among males.     

THE ROLE OF MARITAL STATUS IN HEALTH SERVICES EXPENDITURES FOR PSYCHIATRIC OUTPATTIENTS

This study tested the hypothesis that married psychiatric outpatients would have lower total health services expenditures than divorced or separated patients. Chart review of the 471 individuals attending an academic medical center outpatient psychiatric clinic during 1994 identified 131 married, 40 separated, and 93 divorced patients. Separated men had significantly higher average total charges ($16,890) than married ($5,279) or divorced ($5,539) men by one-way ANOVA (p < .05). The nonparametric Mann-Whitney test also showed that separated men had higher charges than married or divorced men. There were no differences between marital status groups for women.     

Predicting Developmental Change in Healthy Eating and Regular Exercise Among Adolescents in China and the United States: The Role of Psychosocial and Behavioral Protection and Risk

This article reports a cross‐national study of developmental change in health‐enhancing behavior—healthy eating and regular exercise—among adolescents in China and the United States. The application of a conceptual framework comprising psychosocial and behavioral protective and risk factors—both proximal and distal and at both the individual and social contextual level—is shown to provide a substantial account of variation in change in those behaviors over a 2‐year interval. The explanatory account has generality across gender, the 3 grade cohorts, and most importantly, across the 2 markedly diverse societies.     

An exploratory study of family‐centred help‐giving practices in early intervention: families of young children with autism spectrum disorder

The purpose of this exploratory qualitative study was to investigate the early intervention (EI) experiences of mothers who have a young child at risk for autism spectrum disorder. Data were collected through observations, interviews and document analyses. Results of the study suggest (i) interpersonal skills of practitioners and provisions for family choice and collaboration lead to positive experiences for mothers; (ii) asset‐based attitudes lead to family progress and competence; (iii) effective partnerships are developed through supportive provider communication techniques; and (iv) satisfaction with EI services results from practitioner responsiveness to help families access resources and facilitate child development.     

Tobacco Control and Smoking Cessation Efforts in an Inner-City African American Community

This paper describes the conceptual framework that guided the development and implementation of a large-scale, community-based health initiative to lower the prevalence of smoking in an urban African American community. This project developed culturally-sensitive approaches to reducing smoking in the community and to promoting tobacco control efforts developed and implemented by community members. A randomized clinical-trial methodology was used to test the efficacy of the culturally-sensitivey community-developed smoking cessation interventions in lowering smoking rates as compared with a self-help approach. Two theoretical models guided the intervention strategies: a macro-level model applicable to the community as a whole, and a psychological process model applicable to individuals. The community model was based on community systems theory and incorporated the Readiness for Change Model which was applied in both the individual and organizational models. In addition, culturally-sensitive data collection methods were developed to improve the reliability and validity of project data, especially in determining the smoking prevalence rates and smoking behaviors of hard-to-reach, inner-city African Americans. Since the health of individuals is related to the health of their communities, smoking cessation and tobacco control activities that are integrated into the framework of the community (Le., churches, city-council, housing developments, community organizations), and incorporate culturally-relevant and specific interventions can be effective methods for achieving behavioral and societal change.
