RECEPTIVITY TO PEER TEACHING AND PEER LEARNING ABOUT THE SAFE AND APPROPRIATE USE OF MEDICATIONS AMONG OLDER ADULTS     

Jennie Y. Chou  Carolyn M. Brown 《Educational gerontology》2013,39(9):761-775

The purpose of this study was to assess receptivity to peer teaching and peer learning about the safe and appropriate use of medications among communitydwelling older adults. The sample was predominately White (88.5%), female (75.9%) older adults with an average age of 80.2 ( - 9.1) years. On average, the participants perceived their health status as good (2.8 - 0.6). In addition, participants reported using an average number of 4.4 ( - 3.3) prescribed medications. The majority (75%) of participants also reported no problems with their medications. With respect to receptivity to peer teaching and peer learning, the participants, on average, were neutral to peer teaching (6.0 - 2.4), but were somewhat receptive to peer learning (6.7 - 2.2). The number of prescribed medications that a participant reported taking and the age of a participant were identified as significant predictors of receptivity to peer teaching and accounted for 14.5% of the total variance ( F = 5.84, df = 2, p = 0.005). For receptivity to peer learning, the number of prescribed medications also was a significant predictor ( F = 7.50, df = 1, p = 0.008). This study provides the initial step to identifying community-dwelling older adults who would be receptive to peer teaching and peer learning about the safe and appropriate use of medications.  相似文献   

例说走出纠错教学困境的几点感悟     

章珏 《中学数学教学》2005,(6):12-13

面对学生的错误,传统的做法是直接把正确的答案教给学生,因为这样可以节省教学时间,增加课堂训练的密度和强度.但评讲不久便发现,错误又死灰复燃,许多同学依然重复"昨天的故事".究其原因,由于这种评讲没有切入学生解题时犯错的真实情境,评讲缺乏针对性,教学的低效性自然也就显现出来了.  相似文献   

Neuromuscular and technical abilities related to age in water-polo players

Testing is one of the important tasks in any multi-step sport programme. In most ball games, coaches assess motor, physical and technical skills on a regular basis in early stages of talent identification in order to further athletes’ development. The purpose of the study was to investigate anthropometric variables and vertical jump heights as a free throw effectiveness predictor in water-polo players of different age groups. Two hundred and thirty-six young (10–18 years) male water-polo players partitioned into three age groups underwent anthropometric variables’ measures and squat- and countermovement-jump tests, and performed water-polo free throws. Anthropometric variables, vertical jump heights and throw speed – as a proxy for free throw effectiveness – resulted different over age groups. Particularly, throw speed changed from 9.28 to 13.70 m · s^?1 (+48%) from younger to older players. A multiple-regression model indicated that body height, squat-jump height and throw time together explain 52% of variance of throw speed. In conclusion, tall height, high lower limb power and throwing quickness appeared to be relevant determinants for effective free throws. Such indications can help coaches during talent identification and development processes, even by means of novel training strategies. Further research is needed over different maturity statuses.  相似文献   

Olympics,Media and Politics: The First Olympic Ideas in Brazilian Society During the Late Nineteenth and Early Twentieth Centuries     

Fabio de Faria Peres  Victor Andrade de Melo 《国际体育史杂志》2016,33(12):1380-1394

Abstract

The Olympic Games of the modern era are powerful global mediated events. Olympic cities receive an overwhelming examination by world media. As the 2016 Olympic host, Rio de Janeiro has been given an enormous amount of attention, both by the international media and researchers who looked at the urban spaces of Rio, the struggles over the hegemony of the city and the social meanings the Olympics bring to the host city’s citizens. However, studies over the historical relationship between Rio, sport and media are rare. This paper addresses the historical uses of the term Olympic by Brazilian media during the late nineteenth and the early twentieth centuries. By looking at the main articles in the newspapers of these periods, we examine the extent to which ideologies over sports have changed the way the Olympics were represented in Brazil’s national imaginary. We demonstrate how the use of expressions associated with the Olympics historically generated a closer appreciation of these events by the public. We also show how political authorities appropriated the Olympics for their own benefit. The paper concludes by asking whether or not the historical lessons from the early Olympic ideas in Brazil have been learned by the 2016 Rio Games organizers.  相似文献   

Synchronized lower limb kinematics with pelvis orientation achieves the non-rotational shot     

Taishu Nakamura  Tasuku Miyoshi  Motoki Takagi  Yasuhisa Kamada 《Sports Engineering》2016,19(2):71-79

A non-rotational (NR) shot is now a well-known scoring move in soccer. To execute the NR shot, it is necessary to deprive the ball of any rotational forces during the impact phase. To execute the NR shot, it is natural that the force vector acting from the foot would pass through the ball’s center of gravity; however, the coordinated motion of the lower limb joint’s angular displacement and the pelvis is still unclear. The aim of this study is to estimate the coordinated leg and pelvis motion during the NR shot as compared to that during instep kicking. Four right-leg dominant college league players were asked to perform a NR shot and an instep kick a total of 10 times each. Hip, knee, and ankle joint angular displacements in the sagittal plane and pelvis yaw and roll rotational motions during both types of kicks were calculated with 14 IR reflective markers using a 3D real-time motion analysis system with a 250-Hz sampling. The Euclidean distances of the joint space of the NR shot and the instep kick were also calculated to detect similarities in the coordinated motion of the lower limb. The results showed that the lower limb joint motions in the sagittal plane were not different; however, the pelvis roll and yaw motions were apparently different, and these phenomena could simulate a pendulum motion with changes in both the vertical and horizontal displacements. These results suggest that the coordinated motion of the lower limb joint’s angular displacement shows high similarity between the NR shot and the instep kick, and the pelvis roll and yaw synchronized orientation is essential for achieving the NR shot.  相似文献   

A dynamic decision model for portfolio investment and assets management     

QIAN Edward Y.  FENG Ying  HIGGISION James 《浙江大学学报(A卷英文版)》2005,6(Z1)

This paper addresses a dynamic portfolio investment problem. It discusses how we can dynamically choose candidate assets, achieve the possible maximum revenue and reduce the risk to the minimum level. The paper generalizes Markowitz's portfolio selection theory and Sharpe's rule for investment decision. An analytical solution is presented to show how an institutional or individual investor can combine Markowitz's portfolio selection theory, generalized Sharpe's rule and Value-at-Risk(VaR) to find candidate assets and optimal level of position sizes for investment (dis-investment). The result shows that the generalized Markowitz's portfolio selection theory and generalized Sharpe's rule improve decision making for investment.  相似文献   

Social Work Intervention with White Collared Employees and Their Families     

Y.?S.?SiddeGowdaEmail author 《International journal for the advancement of counseling》2004,26(4):421-432

This investigation presents a framework for understanding and also to test the efficacy of Social Work intervention on the well being of the white collared employee (industrial employee) and his/her family. A comprehensive and intensive personal- family exploration was done to uncover the relatedness of seemingly disparate areas of the clients lives. A total of 80 executives (industrial employees) served as subjects. A baseline assessment was done using structured, standardized interview-schedules/questionnaires. The results of the study can be enumerated as follows: After the Social Work intervention, the executives in occupational profile, there were significant changes in Role perception, overload, role conflict, low status and poor peer relations. In coping strategies there was significant improvement in sub-scales like problem solving and unproductive coping. Significant reduction was noticed in their proneness to heart disease, depression, inadequate mental mastery, and perceived ill health. There was significant improvement in their family group support, and in their expressiveness, achievement, orientation, active-recreational and organizational characteristics.  相似文献

A symplectic eigensolution method in transversely isotropic piezoelectric cylindrical media     

徐新生 顾佥梁以德  郑建军 《浙江大学学报(A卷英文版)》2005,6(9):922-927

INTRODUCTION Since the phenomenon of piezoelectricity in natural crystals was discovered in 1880, it has been applied in many fields, such as smart structure, sensing devices and active control, because of its special properties. Combining electrical behavior with mechanical deformation is the special property which attracted great interest of researchers. Many models have been developed for studying piezoelec- tric effects. Dunn and Wienecke (1996) used Green’s functions for transverse…  相似文献   

White Privilege,Oppression, and Racial Identity Development: Implications for Supervision     

Danica G. Hays  Catherine Y. Chang 《Counselor Education & Supervision》2003,43(2):134-145

Although the U.S. population is becoming increasingly diverse, the race of individuals entering the counseling profession remains predominantly White (S. P. Pack‐Brown, 1999). The authors define and explore the connection between White privilege and oppression and encourage the use of racial identity models to address these constructs with counselor trainees in supervision.  相似文献
