论旅游合同纠纷的精神损害赔偿

传统观点认为,违约之诉并不能提起精神损害赔偿的请求。结合我国的立法、司法实践和国外的违约精神损害赔偿的比较法考察,在旅游合同这类特殊性质的合同违约中,应当确立精神损害赔偿制度,以加强对旅游者的保护,并为未来我国的旅游立法工作提供理论支持。

CBA优秀内外球员攻防技术能力的比较研究

运用文献资料法、数理统计法,对CBA后卫、前锋、中锋不同位置的国内外优秀球员攻防技术进行统计与分析,结果表明:1)外援后卫是典型的攻击后卫,具有超强的个人攻击能力,而国内后卫则多数为组织后卫,攻击能力相对弱;2)CBA外援前锋球员出色的身体素质和全面的攻守技术,是内外球员产生较大差距的主要因素,但从防守数据反应了国内前锋积极、认真的防守态度;3)外援中锋进攻范围大,中投与篮下强攻相结合,面对与背对球篮攻击相结合,攻击方式多.3个位置国内球员的攻守及对抗能力与外援相比存在较大差距.建议国内球员加强身体素质训练,提升克托莱指数,着重提高各位置的核心技术水平.     

Role of objectively measured sedentary behaviour in physical performance,frailty and mortality among older adults: A short systematic review

Sedentary behaviour (SB) has recently emerged as an independent risk factor for different health outcomes. Older adults accumulate long time in SB. Understanding the role that SB plays on health is crucial for a successful aging. This short systematic review summarizes the current evidence related to the effects of objectively measured SB on frailty, physical performance and mortality in adults ≥60?years old. The literature search produced 271 records for physical performance (n?=?119), frailty (n?=?31), and mortality (n?=?121). Finally, only 13 articles fulfilled the inclusion criteria and were included in this review. All articles but one included in the physical performance section (n?=?9) showed a negative association between longer time spent in SB and physical performance. A significant association of SB with higher odds of frailty was found, however this association disappeared after adjusting for cognitive status. Lastly, two of the three included studies showed positive associations between SB and mortality, but this effect decreased or even disappeared in the more adjusted models. In conclusion, there is consistency that SB is negatively associated with physical performance. However, the relationship between objectively measured SB and frailty incidence and mortality rates remains unclear and deserves further research. The use of homogenous criteria to assess SB and the inclusion of more robust research designs will help clarifying the independent effects that SB could have on physical performance, frailty, and mortality. This will ultimately help designing more efficient and comprehensive physical activity guidelines for older adults.

积极幻觉与当代积极心理学

积极幻觉是积极心理学的重要组成部分,是个体在生活中或在面临威胁性情景、压力性事件时所做出的一种对自我、现实生活和未来的消极方面的认知过滤。它主要包括自我概念的理想化、夸大对可控性的感知和不现实的乐观三种表现形式。问卷法是目前研究积极幻觉的主要方法。积极幻觉对人类和个体有着重要意义,主要涉及选择性注意、良性遗忘、容忍能力不足和消极自我图式等认知加工过程。相关研究主要集中在生理与心理健康、恋爱关系、学业成绩以及跨文化领域。未来的研究方向是丰富积极幻觉的负性研究,拓展积极认知的研究领域,开发本土化的测量工具等。     

终身教育视野下的教师教育观

终身教育思想对全球教师教育带来深刻影响,人们从此深刻认识到教师教育的连续性和终身性。通过对终身教育理念倡导下教师教育观的解读,使我们更加深刻认识了教师教育的本质和目的。从终身教育思想的视野下来审视我国教师教育的现状,不难看出我国的教师教育存在诸多问题,笔者想通过这些问题,让人们来共同关注我国的教师教育及其发展。     

Basic fibroblast growth factor alleviates brain injury following global ischemia reperfusion in rabbits

The aim of this study was to explore the protective effect of basic fibroblast growth factor (bFGF) on brain injury following global ischemia reperfusion and its mechanisms. Brain injury following global ischemia was induced by four vessels occlusion and systemic hypotension. Twenty-four rabbits were randomized into three groups: group A, only dissection of vessels; group B, intravenous infusion of normal saline after reperfusion for 6 h; group C, 30 μg/kg bFGF injected intravenously at the onset of reperfusion, then infused with 10 μg/(kg·h) for 6 h. Serum neuron specific enolase (NSE), S-100B, tumor necrosis factor-α(TNF-α), interleukin-1 (IL-1), interleukin-8 (IL-8) were measured before ischemia, 30 min after ischemia, 0.5, 1, 3, 6 h after reperfusion. Brain water content was determined and cerebral histopathological damages were compared. NSE and S-100B were increased 1 h after reperfusion and reached their peaks 6 h after reperfusion, but were much higher in group B than those in group C 3, 6 h after reperfusion. In groups B and C, TNF-a was increased after ischemia and IL-1 and IL-8 were increased significantly 0.5 h after reperfusion, then reached their peaks 6 h, 3 h, 6 h after reperfusion respectively. TNF-a and IL-8 at the time points of 1 h and 3 h and IL-1 at 3 h and 6 h in group C were correspondingly lower than those in group B. These indices in group A were nearly unchanged. There were less severe cerebral histopathological damages in group C compared with group B, but no difference in brain water content. It could be concluded that bFGF alleviates brain injury following global ischemia and reperfusion by down-regulating expression of inflammatory factors and inhibiting their activities.
