Public library facility closure: An investigation of reasons for closure and effects on geographic market areas

Through a nationwide survey of potential public library closures from 1999–2003 (the most recent federal dataset at the time of the study), the researchers assessed the reasons for public library closure, actions taken to alleviate possible loss of library services and resources, and the potential effects on users from the librarians' perspective. Geographic information systems (GIS) was used to analyze the demographics and socioeconomics of the geographic market areas around permanently closed library facilities and compared with national averages from the 2000 U.S. Census. The study found a variety of factors lead to closure; however, a lack of use, a sudden reduction in funding, and the opening of another library facility were the most common closure reasons. The actions taken by the community or library system to alleviate the loss of library services and resources depended on the circumstances of each closure. The geographic market areas around permanently closed facilities tended to include poorer and less educated patrons, and more renters than homeowners when compared to the national average from the 2000 U.S. Census. The study presents a methodology using GIS to describe libraries' geographic market areas and illustrates the need for further exploration into reasons for public library closures and the effects of facility site location, relocation, and permanent closure on potential users.     

Analysis of coaching science research published from 1970-2001

The study followed a four-phase design. In Phase I an exhaustive search was conducted for all English language coaching research published in journals from 1970 to 2001. In Phase II, copies of the research were obtained. An expert panel conducted a manual search and a review in Phase III to address validity. Analysis of the research was completed in Phase IV (Culver Gilbert, & Trudel, 2003; Silverman & Skonie, 1997). Over 1,100 articles were reviewed, and 610 met the inclusion criteria. Selected findings include: (a) a relatively low mean spread across many journals, (b) a focus on coaching behavior using quantitative methodologies, and (c) a primary emphasis on team sports in school contexts.     

The influence of communal vs. individual learning context on the academic performance in social studies of grade 4–5 African-Americans

Empirical research utilizing the communal learning construct suggests that culturally-informed pedagogy enhances academic performance for African-American children. The present investigation examined the effect of culturally-informed learning contexts on recall performance in geography lessons. The sample consisted of 69 African-American Grade 4–5 public school students. Weeks 1 and 2 consisted of both learning and testing phases. Week 3 consisted only of a testing phase. Analyses of variance techniques revealed that, overall, subjects in the communal learning context performed significantly better on each of the two weekly quizzes and on the comprehensive examination than those in the individual learning context. Limitations of the findings and future research directions are discussed.     

The Talent Development Model of Schooling: Placing Students at Promise for Academic Success

The work at the Center for Research on the Education of Students Placed At Risk (CRESPAR) has been guided by the Talent Development model, a comprehensive paradigm for school reform. The Talent Development model asserts that all students can learn in demanding, high-expectation academic settings. This goal is reachable if schools are committed to implementing multiple, evidence-based activities to "overdetermine success," and if all relevant stakeholders are genuinely involved, supportive, and held accountable. First, however, the traditional function of schooling must be redirected from that of classifying, sorting, and weeding out students to maximizing every child's potential for academic development. The model is itself a work in progress. Research done at CRESPAR is presented to demonstrate how we are building and evaluating it, with the ultimate aim to contribute to preparing our nation's children for productive participation in their communities and society at large.     

Course of depression and anxiety symptoms during the transition to parenthood for female adolescents with histories of victimization

The aim of the current study was to increase understanding of how victimization history impacts the longitudinal course of depression and anxiety in a sample of 55 adolescents emerging into parenthood. Adolescents were interviewed about their victimization experiences during their second trimester of pregnancy, and interviews were subsequently classified according the Maltreatment Classification Scale (Barnett, Manly, & Cicchetti, 1993). Adolescents reported on their symptoms of depression and anxiety prenatally and 6 and 12 months postpartum. Growth curve modeling revealed that, on average, there was a steady linear decline in depression and anxiety symptoms across the transition to parenthood, with a rate of change of 25% and 20%, respectively, from the prenatal assessment to 12 months postpartum. Sexual abuse history attenuated the likelihood of a decrease in depressive symptoms over time. Neglect history was associated with higher prenatal levels of anxiety, as well as a steeper decline in anxiety symptoms over time. Future research is needed to determine the role of poly-victimization in predicting the onset and change of depression and anxiety symptoms. Findings from the current study have the potential to aid in the design of preventative and intervention efforts to reduce risks of mental health difficulties in adolescent parents.     

Effect of asthma and six-months high-intensity interval training on heart rate variability during exercise in adolescents

ABSTRACT

Little is known regarding the influence of asthma and exercise, and their interaction, on heart rate variability (HRV) in adolescents.

Thirty-one adolescents with asthma (13.7±0.9 years; 21.9±3.9 kg·m^?2; 19 boys, 12 girls) and thirty-three healthy adolescents (13.8±0.9 years; 20.3±3.2 kg·m^?2; 16 boys, 17 girls) completed an incremental ramp test and three heavy-intensity constant-work-rate cycle tests. Thirteen adolescents (7 boys, 6 girls; 6 asthma, 7 control) completed six-months high-intensity interval training (HIIT) and were compared to age- and sex-matched controls. Standard time-domain, frequency-domain and non-linear indices of HRV were derived at baseline, three- and six-months.

Asthma did not influence HRV at baseline or following HIIT. Total power, low frequency and normalised low frequency power, and sympathovagal balance increased at three-months in HIIT, subsequently declining towards baseline at six-months. Normalised high frequency power was reduced at three-months in both groups, which was sustained at six-months. No effects of HIIT were observed in the time-domain nor in the non-linear indices.

HRV was not influenced by asthma, potentially because such derangements are a function of disease progression, severity or duration. HIIT may be associated with a short-term shift towards greater sympathetic predominance during exercise, perhaps caused by physiological overload and fatigue.
