Economically Disadvantaged Urban Female Students Who Achieve in Schools

Recently, researchers at the National Research Center on the Gifted and Talented completed a three-year study of thirty-five economically disadvantaged, ethnically diverse, talented high school students who either achieved or underachieved in their urban high school. In this article, the results are discussed of the case study analysis of nine high-achieving female students who participated in the larger three-year study. Qualitative methods were used to examine the perceptions of students, teachers, and administrators about the reasons that some academically talented students achieve at high levels. Female students who achieved in school acknowledged the importance of being grouped together in honors and advanced classes for academically talented students, and of receiving support and encouragement from each other and from supportive adults, including teachers, guidance counselors, coaches, and mentors. Females who achieved in school participated in multiple extracurricular activities both after school and during the summer. Most high-achieving females in this study chose not to date in order to be able to concentrate their energies on their studies. They also had a strong belief in self and were resilient about negative aspects of their families and their environment. Although parents of students in this study cared deeply about their children, their involvement in their children's high school education was minimal.     

Permanent and temporary work practices: knowledge integration and the meaning of boundary activities

Knowledge integration is a critical topic in current knowledge management research and practice. Research on this topic focuses primarily on how knowledge is integrated within a work setting. A less researched area is knowledge integration between different work groups. The purpose is hence to describe and analyze how knowledge is integrated between different work groups. We present two intensive case studies – one permanent and one temporary (project) work settings – which were studied using a practice-based perspective. A main result of the study is that knowledge integration in the two cases was more complicated than the literature suggests. Both differences and similarities were found between the two cases. Differences were seen in the use of boundary spanning activities and boundary objects, whereas similarities were found in the organizational structures and mechanisms, that is, purposes, rules, and infrastructures, which facilitated the integration of knowledge and/or functioned as obstacles and impediments.

Upper extremity bone mineral content asymmetries in tennis players: A systematic review and meta-analysis

The aim of this study was to examine the magnitude of upper extremity bone mineral content (BMC) asymmetries in tennis players. Furthermore, the influence of sex (male versus female versus mixed), chronological age (juniors: < 18 years; adults: 18–39 years and seniors: ≥ 40 years) and starting age (early starters: < 14 years and late starters: > 18 years) on these asymmetries were examined. Two databases were searched for scientific articles that examined upper extremity BMC in tennis players. Pooling of the individual study effect sizes was conducted using the random-effects model. Three subgroup analyses were performed based on sex, chronological age and starting age. Out of the 15 included studies 24 effect sizes were extracted resulting in a significant difference in BMC value between the dominant and nondominant upper extremity of the tennis players (Standardised Mean Difference: 0.85 [95% CI: 0.67–1.03]). The three subgroup analyses all showed medium to strong effect sizes and significant intergroup differences. To conclude, BMC was significantly higher in the dominant upper extremity compared to the nondominant upper extremity in tennis players. Nevertheless, the influence of training volume and playing experience on these asymmetries are yet to be examined.     

Beyond the residents–businesses clash – urban movements and cultural struggles in Shida,Taipei (2007–2015)

Between the mid-2000s and the early 2010s, the neighborhoods around National Taiwan Normal University (NTNU), an area widely known as Shida, unexpectedly became a tourist hotspot due to the rapidly expanding night market there. Dissatisfied residents mobilized, and for several years they engaged in intense legal and discursive clashes with area businesses, the Taipei City government, and other groups in the community. Drawing on long-term observation, ethnographic research, and in-depth interviews, this article explains Shida’s spatial change from the perspectives of urban movements and cultural struggles. Specifically, it describes how three groups in Shida became organized around divergent purposes, values, and imaginations of the community. Deploying different cultural resources – ranging from civic culture, subcultural ethics to community building – the groups further enter into complex negotiation with the spheres of politics and economics. Ultimately, there was no consensus reached in the Shida case, and though many lament the passing of the area’s unique culture and many of its businesses, the dynamics between the small-scale mobilizations in Shida generated invaluable critical local wisdoms that acknowledge the desire for multiple communities in a physical locality.     

Assay validity of point-of-care platelet function tests in thrombocytopenic blood samples

IntroductionPoint-of-care (POC) platelet function tests are faster and easier to perform than in-depth assessment by flow cytometry. At low platelet counts, however, POC tests are prone to assess platelet function incorrectly. Lower limits of platelet count required to obtain valid test results were defined and a testing method to facilitate comparability between different tests was established.Materials and methodsWe assessed platelet function in whole blood samples of healthy volunteers at decreasing platelet counts (> 100, 80-100, 50-80, 30-50 and < 30 x10⁹/L) using two POC tests: impedance aggregometry and in-vitro bleeding time. Flow cytometry served as the gold standard. The number of platelets needed to reach 50% of the maximum function (ED₅₀) and the lower reference limit (ED_ref) were calculated to define limits of test validity.ResultsThe minimal platelet count required for reliable test results was 100 x10⁹/L for impedance aggregometry and in-vitro bleeding time but only 30 x10⁹/L for flow cytometry. Comparison of ED₅₀ and ED_ref showed significantly lower values for flow cytometry than either POC test (P value < 0.05) but no difference between POC tests nor between the used platelet agonists within a test method.ConclusionCalculating the ED₅₀ and ED_ref provides an effective way to compare values from different platelet function assays. Flow cytometry enables correct platelet function testing as long as platelet count is > 30 x10⁹/L whereas impedance aggregometry and in-vitro bleeding time are inconsistent unless platelet count is > 100 x10⁹/L.     

Synergy and Tension between Large-Scale and Classroom Assessment: International Trends

The synergy, or lack thereof, between large-scale and classroom assessment has been fiercely debated in both academic and policy spheres for decades around the world. This paper seeks to explicate how different countries are utilizing large-scale testing and test results at the classroom level. Through country profiles, this paper analyzes contemporary developments on the tensions and synergies between large-scale assessment and classroom teaching, learning, and assessment observed across seven international jurisdictions: United States, Canada, Australia, England, Germany, Finland, and Singapore. The paper concludes with an analysis of international trends leading to a synthesis of root causes contributing to the current limited uptake of large-scale assessment results at classroom levels.     

Beauty Ideals from Reality Television and Young Women’s Tanning Behavior: An Internalization and Self-Objectification Perspective

The current cross-sectional study among 444 young Belgian women (M_age = 20.08; SD = 0.91) examined the influence of reality television exposure on tanning behavior, which is known to be a risk factor for the development of skin cancer among young women. In addition, it was explored whether the internalization of sun tan ideals from media content and self-objectification could explain this association. As such, this study introduced body image perspectives into media health research. A structural equation model revealed that watching reality television was related to the internalization of sun tan ideals and self-objectification. In turn, the internalization of sun tan ideals and self-objectification related to exposure to harmful UV radiation. This study therefore provides evidence for the explanatory value of both mechanisms in the relationship between reality television and UV exposure. Implications for skin cancer prevention campaigns are discussed.     

Grade and speed have greater influence on HR and RPE than ability,sex, and age in alpine skiing

The purpose of this study was to investigate the influence of ski slope grade, skiing speed, skiing ability, sex, and age on HR, RPE, and energy expenditure responses during recreational alpine skiing. Thirty-eight participants were divided by age, sex, and skiing ability. Instructor- and self-paced skiing conditions were conducted on 10° and 19.8° slopes. Skiing HR was recorded, RPE collected at the end of each run, and energy expenditure calculated. The pertinent results of this study demonstrate that the interactions of grade × speed, speed × age, and grade × age and the main effects of speed and grade significantly influenced %HRmax, mean HR, RPE, and energy expenditure during skiing. When %HRmax is taken into account, the older skiers skied at a greater relative intensity than the young skiers. The sex, age, and skiing ability main effects did not have a significant influence on mean HR, RPE, and energy expenditure. These data demonstrates that increased speed and grade results in increased physiological stress. Using mean, HR data may not be the best option for assessing physiological stress during exercise in the older athlete as it does not account for the influence of the ageing process.
