Abstract We examined relationships between skinfold (SKF) and optical density (ΔOD) measurements across age and levels of body fatness (%BF) for 151 women, 20 to 72 years. There were significant (p < .05) relationships between ΔODs and SKFs at all sites, except the thigh. The interaction (SKF × Age) was significant (p < .05) for pectoral and biceps ΔODs. Slope comparisons indicated the relationships for younger (29 years) and older (59 years) women differed significantly from zero and each other (p < .05). Analysis of SKF × %BF interactions revealed that relationships between SKFs and ΔODs at the pectoral and biceps sites for leaner (22% BF) women differed significantly from zero (p < .05) and were larger than those for obese (39% BF) women (p ≤ .05). Thus, the relationship between SKFs and ΔODs is stronger for younger and leaner women compared to older and fatter women. These findings may reflect differences in fat layering due to age or body fatness and provide insight as to why the manufacturer's near-infrared (NIR) equation significantly underestimates the %BF of obese women. 相似文献

In the two decades since Audre Lorde (1984) pointed out that we have no patterns for relating across our differences as equals (p. 115), struggles to transform higher education have come to focus on communication about and across differences. Despite these efforts, conversations in higher education about group difference and equity too often exacerbate feelings of cynicism and disenfranchisement. In this article we discuss research into the actual discourses at work in communication about the cultural politics of institutional practices. We report on an analysis of qualitative data, using this data to help clarify the challenges of relating across differences as equals.Patrick Bruch is Assistant Professor of Writing Studies in the General College at the University of Minnesota, Twin Cities. He received a B.A. in English from Western Michigan University and a Ph.D. in English from Wayne State University. His teaching and research focus on struggles for equality within and through higher education. He thanks Mark Pedelty for helpful feedback on an earlier draft of this article. Rashné Jehangir received her B.A. in Psychology from Lawrence University and her M.A. in Counseling and Student Personnel Psychology from the University of Minnesota. She currently serves as an Associate Counselor Advocate for first-generation, low-income students in the TRIO Student Support Services program in the General College, University of Minnesota. Her current publications focus on cooperative learning, learning communities, and social justice and access policy to higher education. Dana Britt Lundell is Director of the Center for Research on Developmental Education and Urban Literacy (CRDEUL) in the General College at the University of Minnesota, Twin Cities. She received her M.A. in English and Ph.D. in Curriculum and Instruction from the University of Minnesota. She is Co-Editor of the CRDEUL monograph and 2004 President of the Minnesota Association for Developmental Education (MNADE). Jeanne L. Higbee received her B.S. in Sociology from Iowa State University and earned both her M.S. in Counseling and Guidance and Ph.D. in Educational Administration from the University of Wisconsin-Madison. She currently serves as Professor and Senior Advisor to the Center for Research on Developmental Education and Urban Literacy, General College, University of Minnesota. Her research interests are related to student development and the access and retention of student populations that traditionally have been underserved in postsecondary educational institutions. Karen L. Miksch is an Assistant Professor at the University of Minnesota, General College. She received her J.D. from the University of California, Hastings College of the Law. Affirmative action programs designed to recruit, admit, and retain a diverse student body, as well as access to college preparatory programs, are two ongoing areas of her research.

This is a retrospective analysis of the performance of a large training program in a combat environment looked at through the lens of human performance technology. Van Tiem, Moseley, and Dessinger's performance improvement/HPT model and strategic, operational, and tactical levels are used to describe effective and ineffective applications of human performance technology in a complex, multinational operation. While some interventions or projects at the training center showed marked improvements in targeted areas, there were numerous opportunities to do even better work, and the ultimate analysis of the effectiveness of the training center remains to be determined. 相似文献

Konzepte zum Einsatz von digitalen Medien verdeutlichen deren Potenziale hinsichtlich einer Unterstützung des problemorientierten,
selbstbestimmten und kooperativen Lehrens und Lernens. Offen ist aber, ob Lehrerinnen und Lehrer dieses Potenzial auch wirklich
nutzen. M?glicherweise werden die neuen Medien lediglich in überlieferte Handlungsmuster integriert. Ziel des Forschungsprojekts,
über das hier berichtet wird, ist es, einen Beitrag zur Entwicklung einer Theorie zum Lehrerhandeln im Medienzusammenhang
zu leisten. Dabei wurden (1) Handlungsmuster von Lehrpersonen beim Einsatz neuer Medien im Unterricht identifiziert und (2)
Hypothesen über m?gliche Zusammenh?nge von Handlungsmuster, Medien-Expertisegrad und Fachzugeh?rigkeit generiert. — Es wurden
Videoaufnahmen von 20 Unterrichtsstunden mithilfe eines niedrig-inferenten Kategoriensystems analysiert und hinsichtlich zugrundeliegender
Grundmuster clusteranalytisch ausgewertet. Die Ergebnisse zeigen, dass auf einer zugrunde gelegten Skala mit den Polen „instruktional“
und „konstruktivistisch“ unterschiedliche Muster von Lehrerhandeln beim Einsatz digitaler Medien im Unterricht identifiziert
werden k?nnen, die sich als traditionell-lehrerzentriert bzw. als innovativ-schülerorientiert beschreiben lassen. 相似文献

Six natural history institutions contributed video and other images to produce a single multimedia exhibit about famous paleontology sites throughout the United States. In Mesozoic Monsters, Mammals and Magnolias, users can view videos of the original excavation of each of the sites and also play computer games relating to each location. This project provides a model for how collaboration among museums can reduce the cost of multimedia exhibits while improving quality and making them available to wider audiences. 相似文献
