The Criterion-Related Validity of the Sit and Reach Test: Replication and Extension of Previous Findings

Abstract

The purposes of this study were to (a) examine the stability and consistency of the Caltrac accelerometer (Hemokinetics, Madison, WI) and an activity record to assess physical activity in children and adults (Experiment 1), and (b) to determine if there is a relationship between parents and their children in physical activity level (Experiment 2). Thirty 5–9-year-old children and their biological parents wore Caltrac accelerometers for three consecutive days (including one weekend day). At the same time, parents completed a Caltrac Activity Record (CAL REC) for themselves and their child. Dependent variables were counts per day for the Caltrac and minutes of light activity and activity for the CAL REC. Between-day correlations for the Caltrac ranged from r = .73 to .87 for the parents (p < .001) and from r = .38 (p < .04) to .79 (p < .001) for the children. An analysis of variance with repeated measures indicated no significant differences for the Caltrac between days for parents and children. Between-day correlations for CAL REC ranged from r = .67 to .91 (p < .05) for parents and r = .36 to .72 (p < .05) for children, and there were no significant differences between days. In Experiment 2, χ² analyses were used to examine familial resemblance in physical activity. Using the Caltrac, familial resemblance occurred in 67% (father and child) and 73% (mother and child) of the families. Using the CAL REC, familial aggregation was present in 70% (father and child) and 66% (mother and child) of the families. Thus, children of active and less active parents exhibited physical activity patterns similar to their parents.     

Effects of external loading on power output in a squat jump on a force platform: A comparison between strength and power athletes and sedentary individuals

The aim of this study was to determine the effects of external loading on power output during a squat jump on a force platform in athletes specializing in strength and power events (6 elite weight-lifters and 16 volleyball players) and in 20 sedentary individuals. Instantaneous power was computed from time-force curves during vertical jumps with and without an external load (0, 5 or 10 kg worn in a special vest). The jumps were performed from a squat position, without lower limb counter-movement or an arm swing. Peak instantaneous power corresponded to the highest value of instantaneous power during jumping. Average power throughout the push phase of the jump was also calculated. A two‐way analysis of variance showed significant interactions between the load and group effects for peak instantaneous power ( P < 0.01) and average power ( P < 0.001). Peak instantaneous power decreased significantly in sedentary individuals when moderate external loads were added. The peak instantaneous power at 0 kg was greater than that at 5 and 10 kg in the sedentary individuals. In contrast, peak instantaneous power was independent of load in the strength and power athletes. Mean power at 0 kg was significantly lower than at 5 kg in the athletes; at 0 kg it was significantly higher than at 10 kg in the sedentary males and at 5 and 10 kg in the sedentary females. In all groups, the force corresponding to peak instantaneous power increased and the velocity corresponding to peak instantaneous power decreased with external loading. The present results suggest that the effects of external loading on peak instantaneous power are not significant in strength and power athletes provided that the loads do not prevent peak velocity from being higher than the velocity that is optimal for maximal power output.     

Relationship between household literacy and educational engagement: Analysis of data from Rajkot district, India

Household engagement in a child??s education is a complex process; depending on the culture and the context, it may be revealed through a variety of behaviours. Using data from one district in rural Gujarat, India, four indicators of a household??s educational engagement were employed to investigate the relationship between household literacy levels and the household??s engagement in the education of its child members. The findings on educational engagement were also compared across households with different wealth and income levels. Uniformly, indicators of household literacy levels were found to be more important in understanding a household??s educational engagement than a household??s wealth and income levels.     

Cyberbullying: through the eyes of children and young people

The topic of cyberbullying is raising international debate and concern. Through the development and dissemination of a questionnaire 12 student researchers were supported in surveying 325 UK students across Years 7, 8 and 9 to gain further knowledge of this area, in relation to children and young people. Results were analysed and comparisons made between gender and age, allowing conclusions to be drawn about the area of cyberbullying and its many elements. Conclusions acknowledge that bullying has entered a “digital era” and professionals and adults require the knowledge and skills to help young people to further understand the issues involved and to protect themselves in this area.     

Preparing MSW Students for Social Work Licensure: A Curricular Case Example

Licensing has been a dynamic tension for the social work profession for many years, specifically in social work education. Increasingly, social work programs are using factors related to social work licensing (pass rates, number of test takers, etc.) as an indicator of programmatic success. Yet few, if any, published papers examine curricular innovations designed to prepare students for social work licensing exams. This article describes the initiative that one MSW program implemented to address licensing preparedness. After a brief overview of social work licensing, this article describes the contextual rationale, implementation, and evaluation of the Licensing Preparation Initiative (LPI). Since its inception in spring 2011, LPI data suggest that students are more knowledgeable about the process for applying to sit for the exam and the content areas of the exam, more prepared to take the social work licensing exam, and more confident in their ability to pass the social work licensing exam once they graduate. This article concludes with specific strategies and resources for designing a curricular initiative to address licensing preparedness.     

Don’t Silence “the Dinosaurs”: Keeping Caution Alive With Regard to Social Work Distance Education

Distance education (DE) in social work programs and studies on its comparable effectiveness with face-to-face education continue to increase. Yet not all faculty are convinced of the results, and this study explores why. Three case studies indicate that reservations center on valuing the process of learning and nonverbal communication. Issues regarding duty of care to families to be served by future social workers primarily educated in a virtual classroom also matter significantly. The trend toward DE may be inevitable, but this does not mean that educators should not voice their concerns; their skepticism has merit, and they have a responsibility to be vocal.     

Early intervention in emotional and behavioural difficulties: the role of Nurture Groups

ABSTRACT

This paper reports on the use of Nurture Groups (NGs) in mainstream infant schools as a promising example of an approach to early intervention for children with emotional and behavioural difficulties. The paper describes the philosophy and nature of NGs and offers empirical evidence supporting their effectiveness. It also describes a diagnostic tool designed to assist in the identification and monitoring of children requiring placement in NGs. In addition, the paper provides a brief account of an empirical study of staff attitudes towards and beliefs about NGs.     

Social service utilisation patterns among children with mild intellectual disability – differences between children integrated into mainstream classes and children in self-contained classes

The role of supporters in facilitating access to and use of technology by people (adolescents and adults) with learning disabilities has not been the primary focus of much of the research that has been undertaken to date. The review of literature presented in this paper suggests, however, that issues of support, risk and safety are emerging as factors that have a significant influence on the quality of technology access and use that adults with learning disabilities experience. There is a need for more research into how the relationship between supporters, technologies, adolescents and adults with learning disabilities is mediated by risk, and this paper offers an original perspective on how positive risk-taking might be a useful conceptual framework to aid in the exploration of this relationship.     

Expanding Learning Opportunities for High School Students With Distance Learning

The purpose of the Synchronous Interactive Video Conference Distance Learning pilot program was to use emerging technologies to expand learning opportunities for students at an urban public high school. Through grant funding, students were able to enroll in Advanced Placement and foreign language courses through an online learning provider. Using case study methodology, the pilot program was thoroughly examined through the analysis of multiple sources of data such as surveys of multiple stakeholders, interviews of program administrators, and the examination of student course documentation. The attrition rate was high at 61.9%. The combination of insufficient time for planning and preparation, lack of support for students, and poor communication was detrimental to the program.
