Confounding compression: the effects of posture,sizing and garment type on measured interface pressure in sports compression clothing

The purpose of this investigation was to measure the interface pressure exerted by lower body sports compression garments, in order to assess the effect of garment type, size and posture in athletes. Twelve national-level boxers were fitted with sports compression garments (tights and leggings), each in three different sizes (undersized, recommended size and oversized). Interface pressure was assessed across six landmarks on the lower limb (ranging from medial malleolus to upper thigh) as athletes assumed sitting, standing and supine postures. Sports compression leggings exerted a significantly higher mean pressure than sports compression tights (P < 0.001). Oversized tights applied significantly less pressure than manufacturer-recommended size or undersized tights (P < 0.001), yet no significant differences were apparent between different-sized leggings. Standing posture resulted in significantly higher mean pressure application than a seated posture for both tights and leggings (P < 0.001 and P = 0.002, respectively). Pressure was different across landmarks, with analyses revealing a pressure profile that was neither strictly graduated nor progressive in nature. The pressure applied by sports compression garments is significantly affected by garment type, size and posture assumed by the wearer.  相似文献   

Informational Sources,Social Media Use,and Race in the Flint,Michigan, Water Crisis     

Ashleigh M. Day  Sydney O’Shay-Wallace  Matthew W. Seeger  Shawn P. McElmurry 《Communication Studies》2019,70(3):352-376

Safe, clean water is necessary for health and well-being. Water issues affect minority and vulnerable populations at disproportionate rates, including the poor and racial and ethnic minorities. An investigation of the relationships of race, social media use, and informational sources during the municipal water crisis in Flint, Michigan, reflects an instrumental view of communication and uses and gratifications theory in this study. Data from 208 Flint residents in 2016 indicated that African American respondents favored interpersonal networks and resources and were more likely than other racial groups to obtain current information about the water crisis via Instagram. Preferred channels and sources to receive additional crisis information varied on the basis of race.  相似文献   

A Phenomenon We Can't Ignore: Performance Improvement Interventions to Address Workplace Bullying     

Matthew E. Ritzman 《Performance Improvement》2016,55(1):14-22

Workplace bullying is a significant problem impacting both individual performance and performance of organizations as a whole. This article describes how a systematic approach was utilized by focusing on the organizational subsystem of human resources as it relates to preventing, identifying, and addressing workplace bullying. Human resource (HR) professionals play a vital role in applying anti‐bullying policies and performance improvement interventions. The article outlines the interventions and policies utilized by HR professionals to alleviate and manage bullying that have been cited in the literature.  相似文献   

Advanced Math Course Taking: Effects on Math Achievement and College Enrollment     

Soo-yong Byun  Matthew J. Irvin  Bethany A. Bell 《Journal of Experimental Education》2015,83(4):439-468

Using data from the Educational Longitudinal Study of 2002–2006, the authors investigated the effects of advanced math course taking on math achievement and college enrollment and how such effects varied by socioeconomic status and race/ethnicity. Results from propensity score matching and sensitivity analyses showed that advanced math course taking had positive effects on math achievement and college enrollment. Results also demonstrated that the effect of advanced math course taking on math achievement was greater for low socioeconomic status students than for high socioeconomic status students, but smaller for Black students than for White students. No interaction effects were found for college enrollment. Limitations, policy implications, and future research directions are discussed.  相似文献

Changing the English Classroom: When Large-scale ‘Common’ Testing Meets Secondary Curriculum and Instruction in the United States     

Sandra K. Cimbricz  Matthew L. McConn 《Changing English: An International Journal of English Teaching》2015,22(4):393-404

This article explores the intersection of new, large-scale standards-based testing, teacher accountability policy, and secondary curriculum and instruction in the United States. Two federally funded consortia – the Smarter Balanced Assessment Consortium and the Partnership for Readiness of College and Careers – prove focal to this paper, as these two organisations are creating new tests that will assess 42–49% of the K–12 student population in the United States in 2014–2015. Because greater teacher accountability for student performance will be given for these tests, there is more reason to pay attention to what these tests measure and what they do not. Our analysis suggests that these new tests will hold secondary English teachers accountable for literacy and disciplinary knowledge outside the field of English and thus raise important questions about what English teachers should, can and will do, especially when their jobs are on the line.  相似文献   

Building Inclusive Pedagogy: Recommendations From a National Study of Students of Color in Higher Education and Student Affairs Graduate Programs     

Chris Linder  Jessica C. Harris  Evette L. Allen  Bryan Hubain 《Equity & Excellence in Education》2015,48(2):178-194

In this study, we share the racialized experiences of 29 students of color in higher education and student affairs graduate programs, focusing specifically on their relationships with faculty, their experiences in classrooms, and the strategies they recommend for inclusion. Participants indicated that they are expected to serve as the racial expert in classrooms and that many faculty fail to effectively facilitate discussions related to race and racism and to intervene in instances of racial microaggressions. Participants convey effective strategies to build racially-inclusive classrooms which include authenticity, vulnerability, and validation.  相似文献   

Exploring ethical issues associated with using online surveys in educational research     

Lynne D. Roberts  Peter J. Allen 《Educational Research and Evaluation》2015,21(2):95-108

Online surveys are increasingly used in educational research, yet little attention has focused on ethical issues associated with their use in educational settings. Here, we draw on the broader literature to discuss 5 key ethical issues in the context of educational survey research: dual teacher/researcher roles; informed consent; use of incentives; privacy, anonymity, and confidentiality; and data quality. We illustrate methods of addressing these issues with our experiences conducing online surveys in educational contexts. Moving beyond the procedural ethics approach commonly adopted in quantitative educational research, we recommend adopting a situated/process ethics approach to identify and respond to ethical issues that may arise during the conduct, analysis, and reporting of online survey research. The benefits of online surveying in comparison to traditional survey methods are highlighted, including the potential for online surveys to provide ethically defensible methods of conducting research that would not be feasible in offline education research settings.  相似文献
