经济主义批判

经济主义认为人的一切行为都是经济行为 ,个人幸福和社会福利绝对依赖于经济增长 ,科技进步可保证经济无限增长。但人的许多行为都不是经济行为 ,人们的基本需要得到满足之后 ,生活幸福就不再依赖于经济增长 ,科技也不能保证经济的无限增长。科技不是万能的 ,科技进步不能使人类随心所欲地改造环境 ,也不能把人类带入只有幸福没有痛苦的天堂。人类对自然环境干预得越强烈 ,受到的惩罚就越严厉。经济主义的可行性 (现实性 )不是与自然规律相符合的可行性 ,而是顺从贪欲的可行性。生态学和现实的生态危机都表明经济主义所指导的生产、生活方式是不可持续的。经济主义在中国也产生了较大影响 ,但中国不能允许经济主义泛滥 ,不能走先污染后治理的道路。     

Moving beyond ethical decision-making: a practice-based view to study unethical sales behavior

Changes in the business environment are rapidly transforming sales practice and pressuring the integrity of key actors in sales. Given that unethical sales behavior is a social activity produced and reproduced by various actors in a complex sales task environment, we introduce a novel research perspective to the study of unethical sales behavior, namely a practice-based view. With knowledge from a systematic literature review and a practice-based view from organization research, we suggest that unethical behavior should be studied as a practice formed through socialization and interaction with relevant others. This view provides an important alternative as well as a complementary perspective to the ethical decision-making paradigm that has dominated the field for several decades. The study answers scholars’ recent calls to strengthen the theoretical foundation of sales ethics research and further extend its perspective toward the social context of sales. With a focus on dynamics, social relations, and the enactment of practices, the practice-based view produces new types of knowledge on unethical behavior and potential new means for addressing it. The article makes suggestions for future practice-based research and proposes several theories for use in studying unethical behavior in currently important sales contexts.     

先入观念对情绪感染力的调节——以教学活动为例

从以往意识性情绪感染的研究中可以推断出, 情绪感染可以被后继的“观念”所调节, 这种观念可以被无意识提取, 那么情绪感染能不能被“先入观念”所调节呢, 即观念先于情绪感染而存在并对情绪感染的最终效果产生影响。实验情境以教学活动为例, 采用被试内设计, 通过实验前的指导语引导学生树立两种教师评价--“权威”教师(积极的先入观念)和“新手”教师(消极的先入观念), 然后给学生播放两位教师的三类教学视频--中性情绪、积极情绪、消极情绪的朗诵视频, 使用BioNeuro八通道生物反馈仪记录学生在观看视频时的生理指标, 每段视频播放后, 要求学生完成《教师课堂情绪感染力评价问卷(学生用)》。实验结果表明, 学生在观看“权威”教师视频时, 其注意力水平不受教师情绪效价的影响, 学生对“权威”教师均能保持较高的“专注”状态, 从而提高了“权威”教师的积极情绪感染力(易感性调节), 而对“新手”教师的“专注”程度较低, 从而削弱了“新手”教师的积极情绪感染力(免疫性调节)。“新手”教师的消极情绪感染力(倦怠)比“权威”教师的消极情绪感染力更强, 这与学生对“权威”教师的消极情绪进行“合理化”解释有关, 从而免疫了“权威”教师的消极情绪感染力。问卷调查结果也表明, 学生对“权威”教师的情绪感染力评价(无论是中性、积极或消极视频)要极其显著好于对“新手”教师的评价。由此说明, 先入观念对情绪感染的调节方式有两种：“专注”和“合理化”, 调节的结果也有两种：“易感性”与“免疫性”。     

事件持续时间对情景模型更新的影响

采用移动窗口技术,探讨文本阅读中事件持续时间对情景模型更新的影响。实验1探讨不同的事件持续时间对情景模型更新进程的影响。结果发现,情景模型的更新受到事件持续时间的影响;实验2探讨在不同的事件持续时间条件下,情景模型的更新符合动态观还是静态观,结果支持了情景模型更新的动态观。该研究表明,事件持续时间与时间转换大小之间的关系对情景模型的更新起着重要的作用。同时,情景模型的更新符合动态观。     

On the primacy of molecular processes in determining response rates under variable-ratio and variable-interval schedules

This study focused on variables that may account for response-rate differences under variable-ratio (VR) and variable-interval (VI) schedules of reinforcement. Four rats were exposed to VR, VI, tandem VI differential-reinforcement-of-high-rate, regulated-probability-interval, and negative-feedback schedules of reinforcement that provided the same rate of reinforcement. Response rates were higher under the VR schedule than the VI schedule, and the rates on all other schedules approximated those under the VR schedule. The median reinforced interresponse time (IRT) under the VI schedule was longer than for the other schedules. Thus, differences in reinforced IRTs correlated with differences in response rate, an outcome suggestive of the molecular control of response rate. This conclusion was complemented by the additional finding that the differences in molar reinforcement-feedback functions had little discernible impact on responding.     

The Journal of the Experimental Analysis of Behavior at zero, fifty, and one hundred

The experimental content areas represented in JEAB in its first volume (1958) and 50 years later in Volume 87 are in many ways similar with regard to research on schedules of reinforcement, research with human subjects, and several other topics. Experimental analysis has not been displaced by quantitative analysis. Much less research on aversive control has been published in recent than in earlier years. Wishes for progress in the next 50 years include experiments on verbal behavior, the sources of novel behavior, and observing responses based on stimuli correlated with escape or avoidance.     

β-受体阻滞剂治疗慢性心力衰竭的哲学发展观

随着科学技术的快速发展和人们认识的不断深入,慢性心力衰竭（CHF）的发病机制处于不断嬗变的过程,CHF的药物治疗概念也发生了根本性的变化。β-受体阻滞剂在CHF的治疗策略中,经历了从禁用到必用的过程,成为了CHF药物治疗的重大突破。大量临床试验表明,β-受体阻滞剂不仅能改善患者预后,而且能明显改善左室的舒张和收缩功能,全面改善患者的血流动力学,提高患者的运动耐量和生活质量,延长生存时间。β-受体阻滞剂在CHF治疗中地位的变化,体现了哲学发展观与疾病的治疗以及药物应用的紧密联系,指导着我们的临床实践,也体现了哲学与自然科学的密切联系。本文将β-受体阻滞剂治疗CHF的新旧观念进行阐述、比较,对其作用机制以及临床用药进行介绍,并对其发展空间进行展望。随着科学的进步,人类有能力从长远的角度控制疾病。     

儿童对观察者预期造成的模糊刺激解释多样性的理解

研究考察6~8岁儿童在由观察者预期造成的对模糊信息有多样解释上的理解.操纵影响观察者预期的因素,包括知觉经验、知识水平、先前经历和偏见,要求儿童预测观察者对局限视野图形或两可动作信息的解释.结果表明,6岁儿童仅对观察者偏见影响其对行动者行为的解释拥有部分理解,他们还不能理解知觉经验和知识水平会影响观察者对视觉刺激的解释,以及先前经历会影响观察者对行动者行为的解释.7岁儿童除了知识水平外,其它三方面的理解都已发展起来.8岁儿童可以理解多种观察者预期造成的解释差异,解释性心理理论比较稳定,但离完全成熟的理解还有一段距离.     

临床思维的逻辑性

卫生法制建设是社会主义法治建设的必然要求,也是卫生与经济、社会协调发展的迫切需要;卫生法制建设需要确立科学的认识观和发展观,需要构架现代化发展战略目标。只有这样,才能务实地推进国家与地方区域的卫生法制现代化进程。
