Turnout, or external rotation (ER) of the lower extremities, is essential in ballet. The purpose of this study was to utilise physical examination and a biomechanical method for obtaining functional kinematic data using hip and knee joint centres to identify the relative turnout contributions from hip rotation, femoral anteversion, knee rotation, tibial torsion, and other sources. Ten female dancers received a lower extremity alignment assessment, including passive hip rotation, femoral anteversion, tibial torsion, weightbearing foot alignment, and Beighton hypermobility score. Next, turnout was assessed using plantar pressure plots and three-dimensional motion analysis; participants performed turnout to ballet first position on both a plantar pressure mat and friction-reducing discs. A retro-reflective functional marker motion capture system mapped the lower extremities and hip and knee joint centres. Mean total turnout was 129±15.7° via plantar pressure plots and 135±17.8° via kinematics. Bilateral hip ER during turnout was 49±10.2° (36% of total turnout). Bilateral knee ER during turnout was 41±5.9° (32% of total turnout). Hip ER contribution to total turnout measured kinematically was less than expected compared to other studies, where hip ER was determined without functional kinematic data. Knee ER contributed substantially more turnout than expected or previously reported. This analysis method allows precise assessment of turnout contributors.  相似文献

Reimaging Public Libraries as Learning Communities: What Library Stories Can Tell Us     

Deborah Eicher-Catt  Mina Edmondson 《Public Library Quarterly》2016,35(3):203-221

This article describes a study conducted in York County, Pennsylvania, on its countywide library system framed within the context of the statewide “Reimaging Libraries” Get Storied initiative, developed and marketed by organizational story consultant, Michael Margolis. Understood as an essential aspect of culture re-imaging and change, narratives were collected from library personnel by undergraduate students at Pennsylvania State University-York as part of a service-learning initiative (directed by the first author). Working closely with the library district consultant (second author), we assess the success of the initiative and make some recommendations for culture reimaging through the practice of storytelling.  相似文献   

Academic socialization,parental educational expectations,and academic self‐efficacy among Latino adolescents     

Fernanda L. Cross  Aixa D. Marchand  Michael Medina  Andrea Villafuerte  Deborah Rivas‐Drake 《Psychology in the schools》2019,56(4):483-496

This study examined the direct association between parental educational expectations and adolescents’ academic self‐efficacy, as well as the moderating influence of parental academic socialization messages. Participants were 148 Latino parent–adolescent dyads with the majority of Mexican origin (80.4%). Most of the parent participants were mothers (85.8%). Adolescents were 13 (46%) or 14 (54%) years of age, and 53% identified as female. Adolescents reported their academic self‐efficacy and perceptions of their parents’ educational expectations; parents reported on their academic socialization messages of shame/pressure and effort regarding academics. The results suggest that, after accounting for parents’ level of education and immigrant status, parental educational expectations were positively associated with adolescent academic self‐efficacy. This association was stronger among adolescents whose parents reported transmitting fewer messages of shame/pressure and academic effort. These results point to the importance of nuances in the content and type of academic socialization messages within Latino families.  相似文献   

Relationship between R&D expenditures and publication output for U.S. colleges and universities     

Paul R. McAllister  Deborah Ann Wagner 《Research in higher education》1981,15(1):3-30

Two large independent sources of data, NSF's University Science Statistics Program Integrated Data Base and CHI Research's bibliometric data base, are brought together in a comprehensive study of the relationships among research resources, as measured by R&D expenditures, and research output, as measured by the quantity and visibility of scientific journal articles. The study is based on approximately 500 U.S. colleges and universities. For each of 11 fields of science, there is strong indication of a linear relationship between R&D expenditures and number of papers. The evidence also indicates a positive relationship between number of cites received per paper and number of papers published, but only for papers published in the basic research journals of the fields of chemistry, physics, and biology.  相似文献   

Cutting apart together: a diffracted spatial history of an online scholarly relationship     

Naomi Barnes  Deborah M. Netolicky 《International journal of qualitative studies in education》2019,32(4):380-393

Drawing on the notion of cutting together-apart introduced by Karen Barad and combining it with Lefebvre’s notion of a flaneur (f. flâneuse) who moves between temporal, spatial and political relationships, this article performs a collaboration mediated by social media, namely blogging and tweeting. It draws on the notion of history, space, and social relationships to describe how two women met online. This collaboration as inquiry is about working together despite our differences – finding places to meet rather than diverge, and to dialogue rather than debate. Through a duo-ethnography of how this relationship worked and did not work, notions about how the digital world can act as a mediator for academic work are explored.  相似文献   

The importance of morphemic awareness to reading achievement and the potential of signing morphemes to supporting reading development     

Nielsen DC  Luetke B  Stryker DS 《Journal of deaf studies and deaf education》2011,16(3):275-288

The ability to access and understand the meaning of multi-morphemic words is essential for age-appropriate literacy growth as well as for achievement in other participants, such as science and social studies, which are so print-dependent. This paper provides a theoretical basis for focusing on the morphology of English when teaching students who are deaf or hard of hearing to read through a review of the literature on the role of morphology in reading for both hearing students and those with a hearing loss. In addition, the authors review the empirical literature on Signing Exact English (SEE), a system of signing English constructed in which the morphology of words is made visible to children who might not be able to hear them. The authors propose that students' use of SEE can provide a bridge to developing the morphemic awareness so necessary for age-appropriate reading development and achievement.  相似文献   

Matters of Form: Questions of Race,Identity, Design,and the U.S. Census     

Deborah Balzhiser  Charise Pimentel  Amanda Scott 《Technical Communication Quarterly》2019,28(1):3-20

This case examines how functionalist approaches manifest culturally based on users’ contexts. The authors conduct a critical visual semiotic analysis of the race and Hispanic origin questions on the 2010 U.S. Census form, demonstrating how incongruities in design potentially harm people. This demonstrates a need for adding critical analyses to design and research and it refocuses the Society for Technical Communication’s value of promoting the public good on to design and documentation in order to fight injustice.  相似文献   

An Examination of Text Complexity as Characterized by Readability and Cohesion     

Deborah K. Reed  Sarah Kershaw-Herrera 《Journal of Experimental Education》2016,84(1):75-97

To better understand dimensions of text complexity and their effect on the comprehension of adolescents, 103 high school seniors were randomly assigned to 4 groups. Each group read versions of the same 2 informational passages and answered comprehension test items targeting factual recall and inferences of causal content. Group A passages had a challenging readability level and high cohesion; Group B passages had an easier readability and low cohesion; Group C passages had a challenging readability level and low cohesion; and Group D passages had an easier readability and high cohesion. Students in Group D significantly outperformed students in Group C (g = 0.78). Although the effect sizes of comparisons among all groups ranged from g = 0.13 to 0.73, no other comparisons were statistically significant. Results indicate that adolescents’ reading comprehension is dually influenced by a text's readability and cohesion. Implications for matching readers to instructional text are discussed.  相似文献   

Exploring anatomy and physiology using iPad applications          下载免费PDF全文

Tandra R. Chakraborty  Deborah F. Cooperstein 《Anatomical sciences education》2018,11(4):336-345

This study examined the use of iPads with anatomy applications (apps) in the laboratory sections of the largest undergraduate course at the university, Anatomy and Physiology, serving more than 300 students. The majority of these students were nursing, exercise science/physical education and biology majors. With a student survey (student opinion) and student practicum grades as metrics, this study determined whether the introduction of this novel mobile technology improved student grades and aided the students in learning the course material. The results indicated that students’ grades improved with the introduction of the iPads, and 78% of the students reported that the iPads facilitated their ability to learn the course material. There was a positive association between frequency of app use and standardized mastery of the course material, as students who used the apps more frequently scored higher and indicated that they felt as though they had learned the material more comprehensively. Owning or having an iPad at home did not have a significant effect on the learning of the material. The general consensus by students was that iPad anatomy apps should be used frequently to better develop student understanding of the course material.
