大学生担忧与焦虑敏感的关系

This research recruited a total of 416 undergraduates to participate in the survey of Peen State Worry Questionnaire (PSWQ) and Anxiety Sensitivity Index-Revised (ASI-R) to examine the undergraduate worry and anxiety sensitivity. The results showed that the PSWQ total score was moderate, and positively correlated with that of ASI-R and its sub-factors. The multi-regression analysis showed that both psychological concern and social concern positively predicted the PSWQ total score. The path model of ASI-R and PSWQ fit well in with the data, in which the predictive effect of ASI-R on PSWQ was positive, explaining 15% of variance of PSWQ. This suggested that the level of undergraduates’ worry is moderate, and positively correlated with their anxiety sensitivity.

High-frequency resistance training does not promote greater muscular adaptations compared to low frequencies in young untrained men

The aim of the study was to compare the effect of resistance training (RT) frequencies of five times (RT5), thrice- (RT3) or twice- (RT2) weekly in muscle strength and hypertrophy in young men. Were used a within-subjects design in which 20 participants had one leg randomly assigned to RT5 and the other to RT3 or to RT2. 1?RM and muscle cross-sectional area (CSA) were assessed at baseline, after four (W4) and eight (W8) RT weeks. RT5 resulted in greater total training volume (TTV) than RT3 and RT2 (P?=?.001). 1?RM increased similarly between protocols at W4 (RT5: 55?±?9?Kg, effect size (ES): 1.18; RT3: 51?±?11?Kg, ES: 0.80; RT2: 54?±?7?Kg, ES: 1.13; P?P?2, ES: 0.54; RT3: 22.0?±?4.6?cm², ES: 0.19; RT2: ES: 0.25; 23.8?±?3.8?cm²; P?2; ES: 0.69; RT3: 23.6?±?4.2?cm², ES: 0.58; RT2: 25.5?±?3.7?cm²; ES: 0.70; P?2; RT3: 21.2?±?4.0?cm²; RT2: 22.9?±?3.8?cm²). Performing RT5, RT3 and RT2 a week result in similar muscle strength increase and hypertrophy, despite higher TTV for RT5.     

医学期刊编辑应重视对论文调查工具的审核 ——以护理期刊为例

通过实例从已得到公认的调查工具和自行编制的调查工具2方面,探讨医学期刊编辑在稿件审理、稿件退修及编辑加工过程中对论文调查工具的审核要点,分析其存在问题的原因,并提出对策。对于调查研究类稿件,医学期刊编辑应对调查工具可能存在的问题进行全面审核,重点包括调查工具的研究主题和目标人群是否与本研究一致,调查工具是否进行了信度和效度评价及其结果是否理想,调查工具如何赋分及其评价标准,调查工具编制过程是否规范,信度和效度评价时样本量等,以保证研究的真实性和结果的科学性。选择调查工具是医学期刊横断面调查类稿件审核的关键点之一,需要引起作者和医学期刊编辑的高度重视。     

大学生生活满意度、自尊、应对方式的调查及研究

采用青少年生活满意度问卷、简易应对方式量表和Rosenberg编制的自尊量表对扬州四所高校460名大学生进行问卷调查,探讨社会人口特征对大学生的学生生活满意度、自尊及应对方式的影响,分析自尊、应对方式与大学生生活满意度的相互关系。结果表明：生活满意度与自尊、积极应对方式之间存在正相关;高自尊、积极应对方式是大学生生活满意度的保护因素。由此可以得出结论：自尊和积极应对方式是影响大学生生活满意度的重要变量。     

The great leap backward: changes in the jumping performance of Australian children aged 11−12-years between 1985 and 2015

Previous data have indicated relative stability over time of paediatric jumping performance, but few data exist since the early 2000s. This study quantified the 30-year secular changes in jumping performance of Australian children aged 11?12-years using data from the Australian Schools Health and Fitness Survey (1985, n = 1967) and Growing Up in Australia’s Child Health CheckPoint (2015, n = 1765). Both cohorts measured jumping performance (standing long jump distance), anthropometric and demographic data. Secular changes in jumping performance means and quantiles were examined using multivariable linear and quantile regression. Between 1985 and 2015, jumping performance declined by 16.4 cm or by 11.2% (standardised change 0.66 SD, 95%CI 0.60 to 0.73). Adjustment for body mass reduced the effect by 32%, although the decline remained (absolute change – 11.1 cm, 95%CI ?12.5 to ?9.7; percent change 7.7%, 95%CI 6.7 to 8.6; standardised change 0.51 SD, 95%CI 0.44 to 0.57). This decline was evident across all quantiles. The jumping performance of Australian children aged 11?12-years has declined between 1985 and 2015, with body mass changes accounting for only part of the decline. Efforts should continue to promote paediatric muscular fitness, reduce adiposity, and aim to reverse this decline in jumping performance.     

上海股票市场资本资产定价模型实证检验

本文对上海股市的资本资产定价模型进行意境必横截面数据检验,研究了股市风险与收益的关系,并对上海股市的特点进行了分析。结果发现上海股市系统性风险与收益存在正相关关系,但并不是ＣＡＰＭ所预料的线性关系,说明还有其它风险因素在股票定价中起着不名忽视的作用;投资者的投机需求大于投资需求,相当多的投资者关注的不是资本的时间价值,而是追求高风险所带来的高收益。     

Maturity status effects on torque and muscle architecture of young soccer players

ABSTRACT

This study investigated the effects of maturity status on knee extensor torque and vastus lateralis architecture of young soccer players. Thirty-four males aged 13–18 years were divided into two groups: pubescent (PUB, n = 15) and postpubescent (POSP, n = 19). Torque by angle interaction was established for absolute [F(2.649, 84.771) = 9.066, p < 0.05] and relative to body mass [F(2.704, 86.533) = 4.050, p < 0.05] isometric torque with the POSP group showing greater values. Muscle volume torque-angle relationship was similar between groups. Absolute, relative to body mass, and relative to muscle volume concentric and eccentric torque-velocity relationship showed a non-significant interaction but a significant group effect in favour the POSP group for absolute and concentric torque relative to body mass. Torque-angle and torque-velocity relationship normalized by body mass allometric exponents showed a non-significant interactions and group effects. Muscle thickness (3.6 ± 0.6 vs. 3.8 ± 0.6 cm), fascicle length (8.3 ± 1.4 vs. 8.9 ± 1.6 cm) and pennation angle (15.0 ± 2.3 vs. 14.3 ± 3.2 degrees) was similar between PUB and POSP groups, respectively. Maturity status did not show a significant effect on muscle architecture and on isometric and dynamic torques when allometrically normalized.
