《独立评论》与“九一八”事变

“九一八”事变后,以胡适为首的北方知识分子以《独立评论》为阵地,对该事变给出自己的建议,期望国民政府能在国联的监督之下直接进行谈判,以空间换时间,大力发展国家实力,并幻想日本主动让步。但最终这些建议都没被采纳或实现,证明了这些知识分子的理想化及其对侵略者认识的不足。     

以小麦再生苗叶片为外植体的愈伤组织诱导再生培养体系建立

以小麦幼胚愈伤组织为外植体,研究继代培养时间、外源激素及叶片大小对小麦试管苗叶片愈伤组织诱导和再生的影响。结果表明：继代培养1～6个月的胚性愈伤组织,有较高的再生苗频率;当生长素浓度为2,4-D2mg／L＋NAA1mg／L、叶片高度为4cm时,小麦试管苗叶片愈伤组织的诱导率最高,从而建立了小麦试管苗叶片愈伤组织诱导和再生的培养体系。     

成吉思汗礼遇丘处机分析——以权力与宗教互动的视角

成吉思汗礼遇丘处机反映了权力与宗教的互为需求关系。成吉思汗开放包容的宗教态度、纳贤意识、贵生心境和关注汉法是促成这一历史事件发生的关键因素。丘处机则适时对帝王的召请做出积极回应。双方都经历了利益考虑和情感取舍的过程。从二人际会可以看出:在中国传统社会中,皇权是宗教发展的巨大推动力量,宗教则有神化皇权、安抚民心和维护秩序等功能;但根本上宗教是依附性的,它不可能对权力产生更为深刻或深远的影响。     

端午节的历史传承与当代复兴

端午节在战国时代初步形成,源于古人虔诚的原始信仰。原始信仰是当时节俗传承的足够动力。魏晋时期原始信仰比以前淡化了,端午节传承的原初动力也消弱了,这时人们加入了纪念屈原等历史人物传说来解释端午习俗,为端午节增加了新的文化内涵和习俗。但是由于端午节习俗不重视家庭团聚和祭祀祖先,在契合儒家文化方面不很显著,因而在魏晋以后的儒教时代出现了传承动力不足的问题。到现代社会,端午习俗面临传承危机。但经研究可见到,端午习俗包含着适合现代文化的丰富要素,可以进行适应现代社会的调适、更新。在重视非物质文化遗产保护的社会背景下,它更有了复兴的契机和动力。     

Can sit-to-stand muscle power explain the ability to perform functional tasks in adults with severe obesity?

This study examined the relationship between sit-to-stand (STS) power and physical function in adults with severe obesity. Thirty-eight adults (age: 44 ± 12 years; body mass index [BMI]: 45.2 ± 7.8 kg/m²) completed evaluations of STS power, strength and functional performance. STS power was measured with a wearable inertial sensor, strength was assessed with the isometric mid-thigh pull, and function was measured with the timed up-and-go (TUG), six-minute walk test (6MWT) and 30-s chair STS. Power and strength (normalised to body mass) entered regression models in addition to age, gender, BMI and physical activity (daily step count). Power displayed large univariate associations with TUG (r = 0.50) and 30-s chair STS (r = 0.67), and a moderate association with 6MWT (r = 0.49). Forward stepwise regression revealed that power independently contributed to TUG (β = ?0.40, p = 0.010), 30-s chair STS (β = 0.67, p < 0.001) and 6MWT performance (β = 0.27, p = 0.007). Power also appeared to be a superior determinant of function compared with strength. Power generated via the STS transfer largely underpins the ability to perform functional tasks in adults with severe obesity, although intervention studies are required to investigate a potentially causal relationship.     

Interorganisational conflict between national and provincial sport organisations within China’s elite sport system: Perspectives from national organisations

In this article, the authors examine interorganisational conflict between provincial and national sport organisations in China. The authors theoretically ground the research in work related to interorganisational relationships and interorganisational conflict. The three case studies are artistic gymnastics, swimming, and cycling, and the authors conducted interviews with 11 staff from the relevant national-level sport organisations. Secondary data was sourced from official publications, websites, and influential domestic media. The key finding is that, whilst famed for its top-down bureaucratic system, there is considerable interorganisational conflict within the Chinese sport system. The extent and characteristics of the national-provincial conflict vary between sports. But there is also some consistency regarding the causes of the conflict and the measures adopted to mitigate the tension. Interorganisational conflict provides a useful heuristic for articulating and understanding the interorganisational relationships within the Chinese elite sport system and hence advances elite sport management research.
