8周指定强度训练对不经常锻炼女生强度-情绪反应的影响

29名不经常锻炼女大学生被随机分成2个实验组和1个对照组,采用RPE生成强度方案,实验组分别以RPE=11和RPE=16的强度训练8周,对照组自由活动,训练前和训练后3组被试均参加10min RPE生成强度运动,运动中3、6、9min及运动后5min自述主观运动体验,以检验不同指定强度训练对不经常锻炼者强度-感情反应的影响.结果显示,积极良好状态有组别主效应和强度×时间交互作用,无训练效应.心理苦恼有测试×强度×时间×组别交互作用.疲劳有测试×强度×组别、测试×强度×时间与强度×时间×组别的交互作用.研究暗示更高强度的健身训练使不经常锻炼者强度-情绪反应的变化更积极.     

后危机时代“弃企逃债”的反思与应对

国际金融危机暴发后,不少地方不同程度出现“弃企逃债”现象并产生一定不良后果。究其原因,既有一些企业及企业主破产心理变态、破产理念失当问题,也有破产生态不良、破产制度硬伤问题。为此,后危机时代应疏导破产心理、确立正确破产观、改善破产生态环境、完善破产法律制度,最大限度、地避免“弃企逃债”,以维护经济秩序,减少社会震动。     

我国服务业与服务贸易发展协同性的实证分析

选取4个影响服务业发展的因素和决定服务贸易的2个因素,建立VAR模型,分析我国服务业与服务贸易发展二者之间的关系。通过Granger因果分析和脉冲响应函数的实证研究,得出现阶段我国服务业与服务贸易之间尚未形成良性的协调发展机制,即服务业与服务贸易之间不存在相互促进的关系。     

“犯案老手”与“侦案神探”——论阿加莎·克里斯蒂侦探小说的设悬与释悬

阿加莎·克里斯蒂作品中悬念设置的主要技巧和方法:一是倒置设悬;二是连环设悬;三是隐形人设悬以及运用哑谜、切隔、反常、危局等方法来故布疑阵,营造氛围。由此说明成功设置悬念能给读者提供多层面的审美参与,成功的侦探小说可以承担起文学的多种审美功能。

Is the medium the message? Perceptions of and reactions to crisis communication via twitter, blogs and traditional media

Value changes and the rapid emergence of media innovations (internet, social web) in society lead to an institutionalization of crisis communication, in which especially new media play a crucial role. The key contributions of the paper include deepening and refocusing the theoretical foundations of crisis communication by experimentally analyzing the effects of traditional and social-media strategies on the recipients’ perceptions of reputation; and by analyzing the effects or crisis responses on the recipients’ secondary crisis communications (e.g., sharing information and leaving a message) and reactions (e.g., willingness to boycott). The results indicated that the medium matters more than the message. For all three dependent measures - reputation, secondary crisis communication and reactions - main effects of medium occurred, whereas the message had only a significant main effect on secondary crisis reactions.

先秦时期的自然灾害与政府应对

先秦时期,各种自然灾害频繁发生,给人民的生命财产带来巨大损失。为减少灾害的发生及危害,统治者积极实施减灾、防灾、救灾政策。政策内容之广泛,体系之完备,影响之深远,值得我们认真学习与研究。     

A pragmatic adaptive enrichment design for selecting the right target population for cancer immunotherapies

One of the challenges in the design of confirmatory trials is to deal with uncertainties regarding the optimal target population for a novel drug. Adaptive enrichment designs (AED) which allow for a data-driven selection of one or more prespecified biomarker subpopulations at an interim analysis have been proposed in this setting but practical case studies of AEDs are still relatively rare. We present the design of an AED with a binary endpoint in the highly dynamic setting of cancer immunotherapy. The trial was initiated as a conventional trial in early triple-negative breast cancer but amended to an AED based on emerging data external to the trial suggesting that PD-L1 status could be a predictive biomarker. Operating characteristics are discussed including the concept of a minimal detectable difference, that is, the smallest observed treatment effect that would lead to a statistically significant result in at least one of the target populations at the interim or the final analysis, respectively, in the setting of AED.     

基于ANSYS的悬索跨越管道地震时程响应分析

以长庆油田输油一处某悬索跨越管桥为工程背景,应用ANSYS建立分析模型,采用时程分析法进行非线性地震响应分析。按轴向、横向、竖向分别输入地震波,分析结构在三种情况下的受力特点对比,得到不同方向的抗震性能。以三、四类场地地震波为输入,考虑不同地震烈度,一致输入和行波效应下结构关键部位位移、应力值,并用时程曲线直观表达参数随时间的变化。探讨了悬跨管桥在不同地震动情况下的受力特点和规律,找出薄弱环节并提出了改进措施,为地震预防及灾后拯救提供了一种有效途径。
