Alterations in IGF-I affect elderly: role of physical activity

The growth hormone–insulin-like growth factor I (IGF-I) axis is an important physiological regulator muscle for development. Although there is evidence that aging muscle retains the ability to synthesize IGF-I, there is also evidence that aging may be associated with attenuation of the ability of exercise to induce an isoform of IGF-I that promotes satellite cell proliferation. However, it is clear that overexpression of IGF-I in the muscle can protect against age-related sarcopenia. Strength training appears to be the intervention of choice for the prevention and treatment of sarcopenia. IGF-I has been implicated in the loss of the muscle with age, and IGF-I expression levels change as a consequence of strength training in older adults. However, it seems that advancing age, rather than declining serum levels of IGF-I, appears to be a major determinant of life-time changes in body composition in women and men. We concluded that resistive exercise is a significant determinant of muscle mass and function. Elevated levels of IGF-I have been found in physically active compared to sedentary individuals. Recent work suggests that IGF-I as a mediator plays an important role in muscle hypertrophy and angiogenesis, both of which characterize the anabolic adaptation of muscles to exercise.     

当代儿童文学中老人角色的神话思维

当代儿童文学中,那些富有智慧的老人虽然生活在科技发达的新时代,但依然喜欢用神话思维解释自然现象,赋予自然现象以迷人的魅力和活泼的趣味,以满足孩子们对茫茫宇宙的好奇心和探求心理.老人角色的神话思维是一种泛灵论的生命体验,是一种“看”世界的方式和对待万物的态度,其中包含着对这个世界的奇妙想象和最美好信念的神秘源泉,并促使小读者将个人的行为纳入统一的宇宙秩序中去,从而与世界万物发生内在的联系.

董事会特征与总经理变更

本文以在上海证券交易所1999年前上市的公司为样本,研究董事会特征等治理变量对总经理变更的影响。研究结果表明,对相对业绩下降公司的总经理变更能起到显著解释作用的变量只有董事会会议的次数和公司的领导结构。而其它治理变量,诸如董事会规模、管理董事比例、独立董事比例、股权集中度、董事会成员持股比例等,未能对总经理变更起到显著的解释作用。     

硕士研究生复试评价体系研究

硕士研究生复试录取工作是研究生招生考试的重要组成部分,事关考生切身利益和教育公平,对于提高研究生招生质量起着至关重要的作用.该文通过问卷调查法确立硕士研究生复试评价体系的一级、二级指标框架;采用层次分析法逐级计算各一级、二级指标权重;再利用平均差系数法微调整面试专家权重;最后通过案例分析法检验所构建的复试评价指标体系的有效性.从而构建更加科学、公正的研究生复试评价指标体系,为高校及科研单位的研究生复试工作提供参考.

Time-Varying Risk Measurement for Ship Collision Prevention

We propose an innovative time-varying collision risk (TCR) measurement for ship collision prevention in this article. The proposed measurement considers the level of danger of the approaching ships and the capability of a ship to prevent collisions. We define the TCR as the probability of the overlap of ships’ positions in the future, given the uncertainty of maneuvers. Two sets are identified: (1) the velocity obstacle set as the maneuvers of the own ship that lead to collisions with target ships, and (2) the reachable velocity set as the maneuvers that the own ship can reach regarding its maneuverability. We then measure the TCR as the time-dependent percentage of overlap between these two sets. Several scenarios are presented to illustrate how the proposed measurement identifies the time-varying risk levels, and how the approach can be used as an intuitively understandable tool for collision avoidance.     

被收购企业的博弈分析

在企业的收购活动中,收购价格始终处于一个相当关键的地位,收购能否成功,很大程度上取决于双方是否能在收购价格上达成一致.本文采用现代博弈论的分析方法,以古诺(Cournot)模型为基础,讨论了均衡收购价格的确定.量化论证了在不完全信息的情况下,最终的均衡收购价格比完全信息的情况下要高.同时指出,企业的资产负债率(Debt-to-Assset Ratio)以及由此形成的加权平均资本成本(Weighted-Average Cost of Capital)对均衡价格方面也有一定的影响.
