Comparison of 2D video and electrogoniometry measurements of knee flexion angle during a countermovement jump and landing task

Quantifying countermovement jump (CMJ) and landing knee flexion angle is important for performance and injury risk assessment. The purpose of the study was to compare electrogoniometer (El-Gon)- and video-derived CMJ and landing knee flexion angle. Twenty-two adults performed three CMJs while knee flexion angle was simultaneously assessed using an El-Gon and video. The average systematic offset (RMSE) of the El-Gon-derived knee flexion angle throughout the entire movement was 7.03°?±?2.69°. Excellent reliability was demonstrated by the El-Gon (ICCavg?=?0.92). Countermovement knee flexion angle, maximum landing knee flexion angle and flexion angle at maximum vertical ground reaction force were 12.0°, 10.9°, and 5.7° higher, respectively, when assessed using El-Gon (p?<?0.001), compared to video. Errors between instruments are likely due to El-Gon crosstalk, misalignment and/or axis determination. The El-Gon is a cost-effective and time-efficient alternative to video analysis for the assessment of knee flexion angle if the error is accounted for and the sensor is precisely attached.     

2008 Community College Futures Assembly Focus: Change Or Die—Keys to Enacting Change in the Community College

The Community College Futures Assembly has served as a national, independent policy thinktank since 1995. Its purpose is to articulate the critical issues facing American community colleges and recognize innovative programs. Convening annually in January in Orlando, Florida, the Assembly offers a learning environment where tough questions are raised, critical issues are discussed, and policy implications are vetted. The focus for the 2008 Community College Futures Assembly was change, a theme taken from the book, Change or Die. This special focus issue of the Community College Journal of Research and Practice highlights the best practices of 30 Bellwether trend-setting institutions.     

中美大对比:在哪儿幸福更容易?

在中国涌现"出国热"的那几年,我们的父辈以及我们都在向往着国外的福利、教育和生活环境。有时候梦见自己身处国外都会是一件乐事,值得人们茶余饭后聊上半天。长大以后,随着国外的YouTube、Twitter和国内各类视频网站以及微博客的兴起,我们越来越多地了解到国外也有贫民窟、国外也有经济危机和失业、国外也有腐败和民主上的不完善,而更可怕的是,国外还有允许携带私人枪支的国民……出国,真的有那么好吗?在这篇文章里,一个地地道道的纽约人将向你叙述一个他自己总结出的结论:在中国,要幸福,并不需要太多。     

Elusive mandate: UNICEF and educational development

The United Nations Children's Fund has rapidly gained prominence as a UN agency promoting educational development. Detailed analysis is presented of UNICEF's transition from being a supplier of emergency goods and services, to a humanitarian role that has diversified to embrace development assistance and promoting the rights of children and women. How these have impacted on the development of UNICEF education is examined. Despite many institutional strengths, it is argued that the need for increased policy clarity in UNICEF education and for greater operational effectiveness remain central to any contemporary understanding of UNICEF's contribution to educational development.     

Unemployment and social class stigmas

Western economies have seen a shift away from a model of job security to a model of work precarity. Cycles of unemployment are a defining feature of the new precarious economy. Given these cycles of unemployment, it becomes imperative to explore the barriers to reemployment. The present study uses stigma communication to explore the intersection of two barriers to reemployment: the stigmatization of unemployment and social class position. Analysis of 40 interviews revealed that the meaning of unemployment changed depending on the perceived social class of an unemployed person. Participants described typical unemployed people as pathologically lazy and unmotivated. Upper class unemployed people were stigmatized as a product of privilege. Middle class unemployed people were relatively unstigmatized. The typical unemployed person merged with the typical unemployed lower class person, suggesting that the dominant meaning of unemployment assumes that unemployment is a lower class phenomenon that is preventable if the lower class person would work harder.     

Prepracticum Service‐Learning: Examining the Relationship With Counselor Self‐Efficacy and Anxiety

Prepracticum service‐learning is an integral part of the curriculum for counselor education students at a large southwestern university. Service‐learning is accomplished by placing novice students in school or community agency settings to acquire early, practical, field‐based experience. Activities are more structured and supervised than in an internship or practicum. Analysis indicated that prepracticum service‐learning had a positive significant relationship with counselor self‐efficacy and a significant negative relationship with student anxiety. However, substantial counseling course work and experience with counseling‐related work both had a stronger influence than did prepracticum service‐learning, indicating that the latter is more appropriate for novice students.
