Discrepancies in accelerometer-measured physical activity in children due to cut-point non-equivalence and placement site

Abstract This study examined dissonance in physical activity (PA) between two youth-specific hip-derived intensity cut-points for the Actiwatch (AW), and compared PA between hip and wrist placements using site-specific cut-points. Twenty-four children aged 11.2?±?0.5 years wore the AW on the right hip and non-dominant wrist during a typical school day. Minutes of sedentary behaviour and vigorous activity were greater using Puyau et al. (2002) cut-points, but light, moderate, and moderate-to-vigorous (MVPA) were greater when derived using Puyau et al. (2004) cut-points (P?相似文献   

Curriculum-Based Measurement as a Predictor of Performance on a State Assessment: Diagnostic Efficiency of Local Norms

With the concurrent emphasis on accountability, prevention, and early intervention, curriculum-based measurement of reading (R-CBM) is playing an increasingly important role in the educational process. This study investigated the differences in diagnostic accuracy and utility between commercial norms and local norms when making high-stakes, local decisions. Scores on Dynamic Indicators of Early Literacy Skills Oral Reading Fluency for 1,374 students in Grades 2 to 5 were used to predict outcomes the Georgia reading achievement test, the Criterion Referenced Competency Tests. Local norms were generated using logistic regression and receiver operator characteristic curve analysis. The generated cut scores were compared to the commercial norms for differences in diagnostic efficiency. The generated cut scores were lower than the commercial norms and had improved diagnostic efficiency. Implications related to educational policy and the use of R-CBM are discussed.     

A Review of Research on School Bullying Among African American Youth: An Ecological Systems Analysis

School bullying and peer victimization are social problems that affect African American youth across various environmental contexts. Regrettably, many of the empirical research on bullying and peer victimization among African American youth has examined individual and direct level influences in silos rather than a constellation of factors occurring in multiple settings, such as home, school, and neighborhood. As a holistic model, the social–ecological framework provides a context with which to situate and interpret findings and draw implications from a broader psychosocial framework, which can be applicable across various systems. We utilize Bronfenbrenner’s (American Psychologist 32:513–531, 1977) social–ecological framework as a springboard for investigating the accumulation of risk contributors and the presences of protective factors in relation to school bullying and peer victimization of African American youth. More specifically, we examine the risk and protective factors occurring in the micro- (i.e., parents, peers, school, and community), exo- (i.e., parental stress), and macrosystem levels (i.e., hypermasculinity, and gender role beliefs and stereotypes). We then discuss implications for research and school-based practice.     

Differences in Career Attitude and Career Knowledge for High School Students with and without Paid Work Experience

A large sample (N =1,279) of high school students was assessedusing the Career Maturity Inventory (CDI-A;Lokan, 1984). The two composite scales ofCareer Development Attitude and CareerDevelopment Knowledge were examined in relationto age, gender and whether the students hadengaged in paid work experience. Levels ofcareer maturity increased with age, and ingeneral, females at all age levels reportedhigher levels of maturity than males. Studentswith paid work experience reported higherlevels of Career Development Attitude thanthose with no paid work experience. CareerDevelopment Knowledge was not associated withpaid work experience. Gender differences alsooccurred, with females with paid workexperience generally reporting higher levels ofcareer maturity than males with paid workexperience. Results are discussed in adevelopmental context.     

The experiences of pupils with SEN and their parents at the stage of pre-transition from primary to post-primary school

The experiences of pupils with Special Educational Needs (SEN) and their parents at pre-transition from primary to post-primary school have received little attention in the literature. The current study investigated these experiences using a mixed methods approach within the Irish educational system. Thirty-two pupils with SEN and 42 parents of pupils with SEN participated in focus groups, and also completed a questionnaire which qualitatively complemented the parental focus groups. Emergent themes for pupils included: things I will miss; fitting in and performing as well as others; laying the groundwork: getting to know new people; and experiencing and talking about ‘going to the new school’. Emergent themes for parents included: losing ground?; information is critical: ‘I’m not asking for the moon, but a bit more information’; I’d like help but I don’t want to make trouble for my child; and challenge and support. Critical issues emerging from the data concerning pre-transition experiences for both pupils and parents are discussed.
