“Gymnasts Are Like Wine,They Get Better With Age”: Becoming and Developing Adult Women’s Artistic Gymnasts     

Natalie Barker-Ruchti  Roslyn Kerr  Astrid Schubring  Georgia Cervin  Myrian Nunomura 《Quest (Human Kinetics)》2017,69(3):348-365

Women’s artistic gymnastics is commonly understood to require early entrance and intense training during childhood. Most gymnasts retire before reaching adulthood. In recent years, the gymnast population at the highest level has “aged.” In this article, we adopt a socio-pedagogical perspective to explore the training contexts, pubertal development, and associated learning 10 older elite gymnasts reported. We develop a cultural perspective of gymnast development and show that transitioning through puberty allowed the gymnasts to extend their careers. Support from their coaches and parents, self-reflective time, and genetic predispositions facilitated the transitioning. Through this, gymnasts gained control over self, body, relationships, and performance. In conclusion, we provide implications for gymnast development practice.  相似文献   

Practices of boundary-work in the collaboration between principals and private sponsors in England’s academy schools     

Natalie Papanastasiou 《教育政策杂志》2017,32(1):82-99

This article presents one of the few qualitative studies to empirically examine the collaboration between private sponsors and principals in the context of England’s academy schools policy. It uses the concept of boundary-work to illuminate the multiple dynamics involved in the collaboration between principals and business sponsors. By analysing qualitative interviews with principals and sponsors from a local authority case study the article reveals the working relationship between these actors to be characterised by three boundary-work practices: drawing, negotiating and contesting boundaries. These practices are described before exploring their implications for existing understandings of England’s academies policy. This analysis directly answers calls in the literature for in-depth case study research which explores the collaboration between academy sponsors and principals, and the article’s interpretivist approach to boundary-work is shown to be a valuable theoretical approach which has received little attention in studies investigating the role of private actors in education. The article concludes by advocating for more studies of education policy to use boundary-work as a lens through which to understand the role being played by new actors in education, and argues that this perspective would be particularly valuable for examining the context of England’s increasingly diversifying schooling landscape.  相似文献   

Using digital images of the zebra finch song system as a tool to teach organizational effects of steroid hormones: a free downloadable module     

Grisham W  Schottler NA  McCauley LM  Pham AP  Ruiz ML  Fong MC  Cui X 《CBE life sciences education》2011,10(2):222-230

Zebra finch song behavior is sexually dimorphic: males sing and females do not. The neural system underlying this behavior is sexually dimorphic, and this sex difference is easy to quantify. During development, the zebra finch song system can be altered by steroid hormones, specifically estradiol, which actually masculinizes it. Because of the ease of quantification and experimental manipulation, the zebra finch song system has great potential for use in undergraduate labs. Unfortunately, the underlying costs prohibit use of this system in undergraduate labs. Further, the time required to perform a developmental study renders such undertakings unrealistic within a single academic term. We have overcome these barriers by creating digital tools, including an image library of song nuclei from zebra finch brains. Students using this library replicate and extend a published experiment examining the dose of estradiol required to masculinize the female zebra finch brain. We have used this library for several terms, and students not only obtain significant experimental results but also make gains in understanding content, experimental controls, and inferential statistics (analysis of variance and post hoc tests). We have provided free access to these digital tools at the following website: http://mdcune.psych.ucla.edu/modules/birdsong.  相似文献   

The effects of testing procedure on critical fall height determination for third-generation synthetic turf     

Dara Twomey  Leonie Otago  Natalie Saunders 《Sports Engineering》2011,13(3):145-151

Test procedures and their accuracy in determining critical fall height (CFH) on sporting grounds are paramount to player safety. The procedure currently adopted for synthetic turf in Australian football [1] consists of four consecutive drops at various drop heights at three test locations on the sample. The quantity and packing of the infill in third-generation turf and the pooling effect of the rubber particles with consecutive drops suggests that the current standard protocol may need re-assessment. Therefore, the purpose of this pilot study was to investigate whether current methods of testing for CFH are appropriate for third-generation synthetic turf or whether an alternative or adapted method needs to be developed. CFH was measured, using a HISUN Uniaxe-II Impact Tester, on 12 combinations of synthetic turf samples (four different products with three shock pad options). Three conditions were investigated on each sample; the existing protocol; an alternative 12 single-drop protocol and four single drops from the CFH determined from the existing protocol. A significant difference was found for both absolute and percentage difference between the existing and 12 single-drop protocol, with p = 0.001 and t = 4.33 and p < 0.001 and t = 6.03, respectively. There was also a significant difference between the CFH reached with and without a shock pad for both the existing protocol and the 12 single-drop protocol. The results of this pilot study demonstrate that differences do occur with alterations to the existing protocol and highlight the need for a more detailed characterisation of testing methods on third-generation synthetic turf and the response of surfaces to them.  相似文献   

The Influence of Rurality and Parental Affect on Kindergarten Children's Social and Behavioral Functioning     

Susan M. Sheridan  Natalie A. Koziol  Brandy L. Clarke  Kristin M. Rispoli  Michael J. Coutts 《Early education and development》2014,25(7):1057-1082

Research Findings: Children's early academic achievement is supported by positive social and behavioral skills, and difficulties with these skills frequently gives way to underachievement. Social and behavioral problems often arise as a product of parent–child interactional patterns and environmental influences. Few studies have examined the role of a salient aspect of children's environments, community locale, in the relationship between parenting practices and child outcomes. Using a large, nationally representative sample, we examined whether preschool parenting practices and children's social-behavioral skills in kindergarten were related to geographic setting (rural vs. city, suburban, and town). Results indicated that rural children experienced greater difficulties with parent-reported externalizing behaviors. Furthermore, rural parents displayed less emotional support than parents in other settings. Preschool parenting behaviors were associated with social skills and behavior problems in kindergarten, as reported by both parents and teachers. Parents' emotional supportiveness was found to account for the relationship between geographic setting and parent-reported children's social skills, such that rural parents who provided less emotional support had children with lower social skills in kindergarten. Practice or Policy: Findings of this research indicate that rural children may face particular risk for behavioral issues and highlight the need for increased behavioral supports in rural communities. Moreover, our results suggest that interventions designed to promote parents' support of children's emotions may have particular utility for rural families.  相似文献   

Archiving the wild,the wild archivist: Bukit Brown Cemetery and Singapore’s emerging ‘docu-tivists’     

Natalie Pang  Liew Kai Khiun 《档案与原稿》2014,42(1):87-97

In recent years there has been growing interest in the discipline of computing in relation to cultural heritage, parallel with developments in greater user participation in archives and advances in documentation work. These trends are reflected in the case of a documentation project of an old Chinese cemetery in Singapore, Bukit Brown Cemetery. This case was characterised by tensions among the ‘wild’ array of emerging individual participants and archivists that took the momentum away from both more formal NGOs and government institutions in documenting, archiving and raising awareness of the heritage of the site when part of it was announced to be set aside for a new highway. The case presents a compelling need for participatory archives, facilitated by computing interventions encouraging public engagement and visits to the site. Being actively involved in the documentation process, the authors reflect on how conceptual frameworks of records may assist in designing new media innovations and informing the ways by which a cemetery may be documented. Through these reflections, the authors argue for the active participation of archivists and records professionals in documentation work, and demonstrate how, in the creation and keeping of records, they shape the collective imagination of the public and other stakeholders in heritage sites.  相似文献   

How golden is silence? Teaching undergraduates the power and limits of RNA interference   总被引：1，自引：1，他引：0  

Kuldell NH 《CBE life sciences education》2006,5(3):247-254

It is hard and getting harder to strike a satisfying balance in teaching. Time dedicated to student-generated models or ideas is often sacrificed in an effort to “get through the syllabus.” I describe a series of RNA interference (RNAi) experiments for undergraduate students that simultaneously explores fundamental concepts in gene regulation, develops cutting-edge laboratory skills, and embraces student-directed learning. Students design a small interfering RNA (siRNA) against luciferase, add it to cells expressing this gene, and then quantitatively assess the siRNA's effect on both intended and unintended targets, using a luciferase assay and a DNA microarray. Because both RNAi and microarray technologies are relatively new, with no clear consensus on their analysis or limitations, students are encouraged to explore different approaches to the design of their reagents and interpretations of their data. The ability to creatively formulate a hypothesis-driven experimental approach to a scientific question and to critically evaluate collected data is stressed. Equally important, this experiment emphasizes how modern scientific ideas emerge, are debated, tested, and decided.  相似文献   

Assessments of Student–Teacher Relationships in Residential Treatment Center Schools     

Kathleen Moritz Rudasill  Amy B. Gonshak  Patrick Pössel  Andrew Nichols  Natalie Stipanovic 《Journal of Education for Students Placed at Risk》2013,18(3-4):193-211

Students in residential treatment center (RTC) schools are likely to have histories of extreme or ongoing relational trauma (e.g., abuse and neglect by primary caregivers), have substantial interpersonal and relationship problems, and exhibit many high-risk behaviors. Accordingly, these students may have particular difficulty forming positive relationships with teachers, yet student–teacher relationship quality in RTC schools has not been empirically studied. This study examines links between RTC school students' assessments of their relationships with teachers and their perceptions of self and others. Participants were 113 students in 2 RTC schools from 5th to 12th grade. Results indicate that male and female RTC students' positive perceptions (of self and others) are linked to positive assessments of their relationships with teachers. However, for girls in RTC schools, negative perceptions of self are linked to less positive assessments of the teacher–student relationship. Implications are discussed.  相似文献
