汉语塞-元-塞音序列语境效应机制探讨

以汉语塞-元音节(/pa/、/pi/和/pu/)及其声学线索的非言语模拟音为语境音,汉语/ta/-/ka/连续体为目标音,在3个实验中考察了语境音对汉语听者识别目标音的影响及潜在机制。实验1发现3个塞-元音节的语境效应与频谱对比效应的预期部分一致,与发音特征理论的预期相矛盾。实验2和实验3发现3个塞-元音节关键声学线索(第二共振峰轨迹)的非言语模拟音和所有共振峰轨迹的非言语模拟音表现出类似的语境效应,二者与3个塞-元音节的语境效应总体上一致,但细节方面存在一些差别。实验结果表明塞-元-塞音序列的语境效应主要源于语境音节关键声学线索的差异,这为听觉理论提供了支持,但语境音的语音范畴也部分影响到3个音节的语境效应模式。另外实验结果发现远离目标音关键声学线索频率区的语境音也促进了特定语音范畴的识别,可能由于语境音激活了相应语音范畴的声学线索。     

Induced Over-Benefiting and Under-Benefiting on the Web: Inequity Effects on Feelings and Motivations with Implications for Consumption Behavior

Inequity in its many forms has been the subject of a number of empirical research efforts. Results show that positive inequity, an over-benefited condition, and negative inequity, an under-benefited condition, have divergent effects on subsequent affects and behavioral tendencies. We embed equity treatments within a motivational structure to predict reactions to a quasi-shopping experience in which these methods operate in concert. Interaction effects—predicted by procedural justice considerations as well as instrumentally based arguments—are also tested whereby technical motivation is crossed with the equity conditions. In testing, an online experiment was created incorporating pre- and posttreatment measures. While completing a hypothetical sale, respondents received either an unanticipated, completed coupon field (the over-benefited group), an uncompleted, empty coupon field (the under-benefited group), or were not prompted with a coupon field (the control group). Results showed strong negative effects on postexposure satisfaction, intention, and desire to complete the purchase in the empty coupon field group, and similar positive effects in the completed coupon field group. Moreover, a model linking preexposure variables (expectations and technical sophistication) to postexposure measures was supported indicating carry-through effects. Lastly, procedural justice and instrumental predictions received mixed support when testing for the interaction between technical motivation and inequity. Results showed that, for those in the under-benefited group, there was only a slight tendency for those with higher levels of technical sophistication to report greater satisfaction; however a strong tendency was found for the same individuals to report a lower likelihood of completing the purchase. Implications for future research are discussed.     

An Influence of Product and Brand Name on Positive Affect: Implicit and Explicit Measures

Results of two studies indicated that tasting a familiar product designed to be refreshing (iced tea), without knowledge of the brand, induced positive affect, as did the gift-of-candy (not consumed) induction, used in many previous studies. As compared to controls, these participants showed more positive affect as reflected by 5 implicit measures and 2~explicit ratings of the refreshingness and pleasingness of the product. They performed significantly better on items from the Remote Associates Test (a test of creativity), generated more unusual and more pleasant first associates to a randomly selected letter of the alphabet, and to neutral words (the implicit measures). Results also indicated that similar affect did not arise when participants tasted a less liked, unfamiliar, brand of iced tea, without knowledge of the brand. However, when the brand name (a known brand) of that tea was presented with the less liked product sample, people who tasted that same tea showed positive affect responses on the implicit measures of affect and also explicitly rated the tea as more refreshing and pleasing than the unbranded version of the same tea.     

Achieving Democratic Equality: Forgiveness, Reconciliation, and Reparations

This paper provides an account of reparationsin general and then presents briefly oneexplanation of why many present day AfricanAmericans believe they are entitled toreparations from the U.S. Government.This explanation should not be seen as a finaljustification, but only as an indication whythe demand for reparations for AfricanAmericans might be seen a plausible. Next, ifit is reasonable to assume that reparations toAfrican Americans are plausible, I then go onto explain why reparations might be necessaryto fill the breech that is perceived to existbetween many African Americans and theirgovernment. This explanation will involve anexamination of the relationship between threeconcepts: forgiveness, reconciliation, andreparations. Then I explore why an apology orreparations for slavery and Jim Crow might benecessary for reconciliation between manyAfrican Americans and their government.Finally, I examine the contention that thelegislative process can be used to obtain anapology or reparations from the government.     

医疗服务公平与效率实现途径的理论探讨

弱势群体与医疗保健服务公平问题初探

我国医疗保健服务中受到不公平对待的主要是弱势群体,这种不公平有来自政策层面的,也有来自各种医疗保健服务实践环节的.为了改善这种现状,促进医疗保健服务公平性,必须做到:党和政府高度重视:积极完善医疗保障体系,重视弱势群体的话语权;摆正公平和效率的关系,构建专门针对弱势群体的医疗救助制度;加强部门之间的合作,共同提高弱势群体的健康水平.     

器官移植的发展与资源分配的公平

器官移植技术是二十世纪医学史上最伟大的成就之一,使世界上数十万濒临死亡的病人获得新生.现在许多国家都开展了这项技术,由于器官供体的短缺使器官移植仍然是一种稀缺资源,又受到卫生资源分配的制约.而卫生资源的分配又要受到社会价值取向的影响.     

Planning bridges the intention–behaviour gap: Age makes a difference and strategy use explains why

Objective: This study examines age-differential association patterns between intentions, planning and physical activity in young and middle-aged individuals. The effectiveness of planning to bridge the intention–behaviour gap is assumed to increase with advancing age. We explore the use of behaviour change strategies that include selection, optimisation and compensation (SOC) as underlying mechanisms for age differences. Methods: In N = 265 employees of a national railway company (aged 19–64 years), intentions, planning, SOC strategy use and physical activity were assessed at baseline (Time 1) and again 1 month later (Time 2). Hypotheses were tested in two different path models. Results: Age moderates the extent to which planning mediates the intention–behaviour relation due to an increasing strength of the planning–behaviour link. As a possible psychological mechanism for these age differences, we identified SOC strategy use as a mediator of the age by planning interaction effect on physical activity. Conclusion: These findings suggest differential mechanisms in behaviour regulation in young and middle-aged individuals.
