基金视角下的学科知识流动网络构建与分析

[目的/意义] 在学科交叉融合的背景和趋势下,科研人员的跨学科研究行为促进了知识在不同学科之间的共享与流动。以基金领域为视角,研究学科知识流动,以期为基金管理工作提出建议。[方法/过程] 提出基于基金代码共现的学科知识流动强度测量方法,并利用社会网络分析方法,对193517个国家自然科学基金项目数据构建学科知识流动网络,探究网络的演变过程以及不同学科层次内知识流动路径。[结果/结论] 通过以上分析,得到如下结论:学科知识流动网络是无标度网络,随着时间的推移,网络的规模和结构都发生显著的变化,网络中重要节点呈非稳态;不同学部之间,存在若干条较为重要的知识流动路径;在某一个学部内,具有较广影响力的一类学科往往更容易构成知识流动链条。

建筑物致人损害责任主体的确认

建筑物致人损害的责任主体是人，而不是物，并且是负有管理义务的人。在司法审判实践中，应区别不同情况来确定建筑物致人损害的责任主体，主要分为管理人有管理义务和管理人无管理义务两种情况。

体育院校冰上运动对男大学生身体成分和骨密度的影响

为探讨冰上运动项目对男大学生身体成分和骨密度的影响,采用韩国ZEUS9.9身体成分分析仪和法国Osteospace MEDI LINK超声骨量测量仪,分别对体育院校2010～2012级冰上运动专项的男大学生和没有运动专项的男大学生进行身体成分和骨密度的测量,并对实验数据进行统计学的分析与比较。结果显示,冰上运动专项男大学生左右腿肌肉含量、基础代谢率显著高于对照组（P＜0.05）,骨密度显著低于对照组大学生（P＜0.05）,这可能与调查对象的生活方式、饮食习惯、训练年限、运动水平以及冰上运动项目的教学内容有关。建议冰上运动专项男大学生改变不良生活方式、均衡饮食,适当调整运动训练方案,加强下肢的力量训练,提高运动成绩。

Reliability of arterial spin labelling measurements of perfusion within the quadriceps during steady-state exercise

Arterial spin labelling (ASL) provides a potential method to non-invasively determine muscle blood flow and examine the impact of interventions such as supplementation and training. However, it's a method with intrinsically low signal, leading to limitations in accuracy and temporal resolution. To examine these limitations, the current study measured perfusion via ASL on three occasions in the rectus femoris of 10 healthy adults, during light and moderate exercise, over three different exercise durations. For data sampled over 9 min, light intensity exercise gave an average perfusion of 35.0 ± 5.1 ml/min.100g^?1 with a coefficient of variation (COV) of 16% and single intraclass correlation coefficient (ICC) of 0.67. For the moderate bout, perfusion was 51.3 ± 5.6 ml/min.100g^?1 (COV 10%, ICC 0.82). When the same data were analyzed over 5 min 24 s, perfusion was 37.8 ± 11.13 (COV 30%, ICC 0.13) during light and 49.5 ± 8.8 ml/min.100g^?1 (COV 18%, ICC 0.52) during moderate exercise. When sampling was reduced to 1 min 48 s, perfusion was 41.2 ± 13.7 (COV 33%, ICC 0.26) during light and 49.5 ± 13.6 ml/min.100g^?1 (COV 28%, ICC 0.04) during moderate exercise. For 9 min a significant perfusion difference was found between the exercise intensities; however, this was not the case for sampling over 5 min 24 s or 1 min 48 s. Such findings illustrate the potential of ASL to non-invasively monitor muscle perfusion under steady-state conditions, but highlight that extended exercise protocols are necessary in order to generate date of sufficient reliability to be able to discriminate intervention dependent perfusion differences.     

The effect of 14 weeks of vitamin D3 supplementation on antimicrobial peptides and proteins in athletes

Heavy training is associated with increased respiratory infection risk and antimicrobial proteins are important in defence against oral and respiratory tract infections. We examined the effect of 14 weeks of vitamin D₃ supplementation (5000 IU/day) on the resting plasma cathelicidin concentration and the salivary secretion rates of secretory immunoglobulin A (SIgA), cathelicidin, lactoferrin and lysozyme in athletes during a winter training period. Blood and saliva were obtained at the start of the study from 39 healthy men who were randomly allocated to vitamin D₃ supplement or placebo. Blood samples were also collected at the end of the study; saliva samples were collected after 7 and 14 weeks. Plasma total 25(OH)D concentration increased by 130% in the vitamin D₃ group and decreased by 43% in the placebo group (both P = 0.001). The percentage change of plasma cathelicidin concentration in the vitamin D₃ group was higher than in the placebo group (P = 0.025). Only in the vitamin D₃ group, the saliva SIgA and cathelicidin secretion rates increased over time (both P = 0.03). A daily 5000 IU vitamin D₃ supplement has a beneficial effect in up-regulating the expression of SIgA and cathelicidin in athletes during a winter training period, which could improve resistance to respiratory infections.     

Multiple components of fitness improved among overweight and obese adolescents following a community-based lifestyle intervention

Fitness is an important component of health, and obese adolescents regularly have poor fitness. Unfortunately, few have assessed the impact of community-based lifestyle interventions on multiple components of fitness. The purpose of this study was to assess the impact of participation in a community-based intervention involving adolescents and parents on multiple components of fitness of obese adolescents. In a within-subject, waitlist controlled clinical trial with 12 months follow-up in Western Australia, participants (n = 56) completed multiple fitness measures at baseline, immediately prior to beginning an 8-week intervention and at 3, 6 and 12 months during a maintenance period. Performance on the shuttle walk was improved immediately post-intervention (increase of 42.8 m, 95% CI: 7.5, 78.2) and at 12 months post-intervention (increase of 44.6 m, 95% CI: 1.3, 87.8) compared with pre-intervention. Muscle performance of quadriceps and deltoids were improved post-intervention (increase of 1.1 (95% CI: 0.1, 2.1) kg · F and 1.0 (0.02, 2.1) kg · F, respectively) and all muscle performance measures were improved at 12 months following the intervention. There were no changes in waist circumference. A community-based lifestyle programme such as Curtin University’s Activity, Food and Attitudes Program (CAFAP) may be a viable strategy for improving fitness in overweight adolescents.
