血液氧自由基、血乳酸、主观用力感觉、心率与运动强度相关性的研究

为探索抗氧化运动强度与监控指标的确定,采用CR2000RC氧自由基生化分析仪、LT 1710血乳酸测定仪、Borg(15、10)主观用力感觉等级量表、心率监测系统对受试者(n=9)从事300、600、900、1200、1500KPM/min不同强度踏车(Monark839E)运动(每级负荷运动5min)时血液氧自由基、血乳酸、主观用力感觉、心率的变化进行测定,并对其进行了相关性分析。结果表明:心率、RPE(15、10)与运动强度(KPM/min)之间呈现高度线性相关,r=0 959、0 923、0 918;血液氧自由基浓度与运动强度、心率、RPE之间的相关性较低,但其变化趋势类似于血乳酸的变化,低强度时(≤900KPM/min)虽运动强度增加但血液氧自由基浓度保持不变,当运动强度超过900KPM/min时,血液氧自由基浓度随运动强度增加而增加;RPE10与血乳酸之间的相关程度高于RPE15、心率、运动强度与血乳酸的相关程度。认为心率、RPE(15、10)可作为监控抗氧化运动强度的理想指标;血液氧自由基浓度不能作为运动强度的监控指标;从抗氧化运动角度而言,健身运动的强度应以血乳酸4mM、心率130beats/min、RPE15值11、RPE10值3左右为宜。     

A Study of the Decision-Making Behaviours of Turkish Adolescents

The research reported in this paper aimed to examine the relationships between decision-making behaviours, self-esteem, and the perceived problem-solving skills of adolescents and to investigate the contributions of self-esteem and perceived problem-solving skills in predicting decision-making behaviours (decision response styles, decisional self-esteem, and decisional stress). Another aim of the study was to investigate whether there is a difference in the decision-making behaviours of adolescents considering gender and school type. For this purpose, Decision Behaviour Questionnaire, Self-Esteem Inventory, and Problem-Solving Inventory were administered to 511 adolescents (276 females and 235 males) in Turkish high schools. The findings revealed that decisional behaviours were positively correlated with self-esteem and problem solving. At the same time, self-esteem (general, social, academic, and home/family) and problem-solving were significant predictors of decisional behaviours. There were significant differences in decisional behaviours according to gender and type of school.     

武术文化传播的障碍因素分析

运用文化学、传播学理论，分析探讨了武术文化传播的重要性，指出，由于存在认识上的误区，导致武术对外传播过程中注重了“物器技术”的传播，而较为忽视武术心理价值的交流。影响武术文化传播的障碍因素有语言、文化背景、兴趣、认知等。

大学生参与休闲体育行为意向模式研究

探讨影响大学生参与休闲体育行为意向的因素,采用问卷调研法对354名大学生进行测量,将影响大学生参与休闲体育的因素,运用计划行为理论与线性结构方程式统计分析,找出影响大学生参与休闲体育行为意向构面的影响力度。实证结果:态度、主观规范和知觉行为控制对行为意向有直接的显著影响,可以解释其参与休闲体育行为意向的0.37;情感性信念和工具性信念对态度有显著影响,可以解释其参与休闲体育态度的0.22;主体群和次体群对主观规范有显著影响,可以解释其参与休闲体育主观规范的0.35;便利条件和自我能力对知觉行为控制有显著影响,可以解释其参与休闲体育知觉行为控制的0.68。研究提出了提高大学生参与休闲体育的行为意向策略。     

Assessing Determinants of Perceived Ease of Use of Institutional Repositories by Lecturers in Nigerian Universities

Abstract

Institutional repositories (IRs) present platform to disseminate research findings to complement the traditional scholarly communication model. The use of IRs is beneficial to authors, host institutions, libraries and society at large. Despite the numerous benefits of IRs, there is low deposit of scholarly works by lecturers and the investment on IRs seems to be a waste. This study examined determinants of perceived ease of use (PEOU) of IRs by lecturers in Nigerian universities. A survey of lecturers received 857 respondents. Awareness, anchor and adjustment factors were found to be determinants of PEOU of Institutional repositories by lecturers in Nigerian Universities.

Perceived and experienced stigma among people living with HIV: Examining the role of prior stigmatization on reasons for and against future disclosures

HIV remains a significant health concern entering the fourth decade of the epidemic [Centers for Disease Control and Prevention. 2014. HIV basics. Retrieved from http://www.cdc.gov/hiv/basics/index.html], and people living with HIV continue to grapple with stigma. This study uses Leary and Schreindorfer's [1998 Leary, M. R., &; Schreindorfer, L. S. (1998). The stigmatization of HIV and AIDS: Rubbing salt in the wound. In V. J. Derlega &; A. P. Barbee (Eds.), HIV and social interaction (pp. 12–29).

Thousand Oaks, CA: Sage] conceptualization of stigma to explore prior stigmatization on reasons for and against future disclosures. We interviewed HIV+ individuals (N?=?59) and used a combination of deductive and inductive coding to analyze participants’ responses. Deductive codes consisted of four stigma characteristics (pose a threat to others’ health and safety, deviate from group standards, create negative emotional reactions in others, and failure to contribute), experiences of feeling stigmatized due to HIV status (yes or no), and the degree to which HIV stigma was a concern (major, minor, or no concern). Inductive coding identified examples of perceived and experienced stigma and stigma concerns on future disclosure decision-making. Practical implications discuss individual, institutional, and societal stigma-reduction interventions and programs.
