A pilot study of a dynamical systems approach to examining changes in static balance of adolescents

In a dynamical systems model, movement patterns are dictated by several variables, called control parameters. The goal of this pilot study was to assess whether changes on a static balance task can be described by a dynamical systems model with body inertial properties as one of the potential control parameters. Three aspects of a dynamic system were examined in relation to a 2-ft. static balance task: a relation between the changes in the balance pattern and the control parameter, a relation between the stability of the balance pattern and the stability under perturbed conditions (1-ft. balance task), and during the perturbation lack of relation between the balance pattern and the control parameters. Nine adolescent boys, 15.3 +/- 1.0 yr. old were examined twice over a 14-wk. period. During each testing session, participants' body mass, moments of inertia, and radius from the ankle to the center of mass were calculated, after which 1- and 2-ft. balance tasks were performed. Center of pressure coordinates were recorded using a Kistler force plate. The body parameters were used to calculate the natural frequency of the body to represent the control parameter. Significant relations among all three aspects of a dynamic system examined in both the lateral and anterior-posterior axes were found. This investigation was designed for exploratory purposes and limited to correlational analysis; therefore, no concrete conclusions could be drawn. The results, however, suggest a dynamical systems approach to the study of static balance patterns may be possible.     

Cystic Fibrosis Prenatal Screening in Genetic Counseling Practice: Recommendations of the National Society of Genetic Counselors

For over a decade, prenatal screening for cystic fibrosis (CF) has been considered a model for the integration of genetic testing into routine medical practice. Data from pilot studies and public policy discourse have led to recommendations by some professional organizations that CF screening should be offered or made available to pregnant women and their partners, and to couples planning a pregnancy. It is crucial that genetic counselors gain thorough understanding of the complexities of CF and the implications of positive test results, so that they may serve as a reliable, educated referral base and resource for health care providers and their patients. While not all pregnant women will be referred for genetic counseling prior to CF carrier testing, genetic counselors often will be asked to counsel clients after they have a positive test result, or who are found to be at increased risk. Genetic counselors can play an important role in providing accurate and current information as well as support for patients informed decisions. These recommendations were created by a multicenter working group of genetic counselors with expertise in CF and are based on personal clinical experience, review of pertinent English language medical articles, and reports of expert committees. The recommendations should not be construed as dictating an exclusive course of management, nor does the use of such recommendations guarantee a particular outcome. These recommendations do not displace a health care providers professional judgment based on the clinical circumstances of a particular client.     

The Relationship Between Parental Knowledge and Monitoring and Child and Adolescent Conduct Problems: A 10-Year Update

Inadequate parental monitoring is widely recognized as a risk factor for the development of child and adolescent conduct problems. However, previous studies examining parental monitoring have largely measured parental knowledge and not the active methods used by parents to track the activities and behavior of their children. The seminal work of Stattin and Kerr (Child Dev 71:1072–1085, 2000; Kerr and Stattin in Dev Psychol 36:366–380, 2000) has challenged the field to reinterpret the construct of parental monitoring, focusing on the active components of this parenting behavior. As a result, this area of research has witnessed a resurgence of activity. The goal of the current paper is to review the evidence regarding the relationship between parental knowledge and monitoring and child and adolescent conduct problems that has accumulated during the past decade. Forty-seven studies published between 2000 and 2010 were identified by searching major databases and bibliographies and were included in this review. This paper will examine the following areas: (a) “parental monitoring” as “parental knowledge”; (b) parental knowledge as driven by child disclosure; (c) the relationship between parental knowledge and monitoring and child and adolescent conduct problems; (d) bidirectional associations between parental knowledge and monitoring and child and adolescent conduct problems; (e) contextual influences on parental knowledge and monitoring; (f) antecedents of parental knowledge and monitoring; (g) clinical implications of research on parental knowledge and monitoring; and (h) limitations of existing research and future directions.     

Reconsidering The Love of Art: Evaluating the Potential of Art Museum Outreach

ABSTRACT

Art museums have long been identified as bastions of social and cultural exclusion. This conclusion was best evidenced by the large-scale 1967 French study by Bourdieu and Darbel demonstrating the exclusionary nature of The Love of Art. However, in recent years there have been increasing efforts to reach out to a broader range of visitors beyond conventional audiences. The present study investigates the impacts of an outreach program at a U.K. art museum, which sought to engage socially excluded young mothers. This study uses ethnographic research methods on a longitudinal basis to develop qualitative insights about the program seeking to mitigate cultural exclusion. Although the study's findings uphold many longstanding critiques of art museums’ conventional approaches, the study also indicates that carefully designed outreach activities can overcome such limitations and enhance cultural engagement. Thus, art museums’ limited appeal is tied to problematic public engagement practices that can be changed.
