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.     

Regarding a Risk‐Pooling System of compensation

In this paper, I propose and defend a distinct and novel approach to compensation for risk impositions. I call it the Risk‐Pooling System of compensation. This system suggests that when X performs an action that imposes a risk of harm to Y, then X is liable to Y, and is therefore obliged to make an ex ante compensation that is roughly equivalent to the expected cost of potential harm to a social‐ risk pool. If and when Y suffers harm as a result of the risk imposed by X, they then receive an ex post compensation roughly equivalent to the cost of actual harm suffered. This system of compensation creates a social buffer between the risk imposer – the one who has the duty to pay compensation into the pool – and the victim – the one who has the right to receive compensation from the social pool. I contend that the Risk‐Pooling System is an improvement over its alternatives due to its capacity to produce the best social utilities, particularly, in terms of reducing information costs, obtaining optimal deterrence in the society and creating incentives for people to be engaged in social activities.     

Judgments in a hurry: Time pressure affects how judges assess unfairly shared losses and unfairly shared gains

Human society has evolved to allow third parties—the court system, parents or other societal arbitrators—to punish norm violators and compensate victims. Few studies explore the effect of stress or time pressure on a third‐party judge. Under time pressure, people will likely show a more instinctual reaction or judgment style. We investigated third‐party punishment and compensation within the context of unfairly shared losses and gains in a dictator game under time pressure. Our results show that under no time pressure, participants were inclined to punish dictators who unfairly split windfall gains; however, participants chose to compensate victims more than punish the norm‐violating dictators in the context of unfairly shared losses. With added time pressure, third‐parties were disposed to inflict punishment upon the dictator in both the gain and loss contexts—punishment became the action of choice. Our results shed light on the way observed behavior and stress affect social cognition and decision making in the context of altruistic social interventions and the enforcement of social norms.     

Impaired sequential and partially compensated probabilistic skill learning in Parkinson's disease

The striatal dopaminergic dysfunction in Parkinson's disease (PD) has been associated with deficits in skill learning in numerous studies, but some of the findings remain controversial. Our aim was to explore the generality of the learning deficit using two widely reported skill learning tasks in the same group of Parkinson's patients. Thirty-four patients with PD (mean age: 62.83 years, SD: 7.67) were compared to age-matched healthy adults. Two tasks were employed: the Serial Reaction Time Task (SRT), testing the learning of motor sequences, and the Weather Prediction (WP) task, testing non-sequential probabilistic category learning. On the SRT task, patients with PD showed no significant evidence for sequence learning. These results support and also extend previous findings, suggesting that motor skill learning is vulnerable in PD. On the WP task, the PD group showed the same amount of learning as controls, but they exploited qualitatively different strategies in predicting the target categories. While controls typically combined probabilities from multiple predicting cues, patients with PD instead focused on individual cues. We also found moderate to high correlations between the different measures of skill learning. These findings support our hypothesis that skill learning is generally impaired in PD, and can in some cases be compensated by relying on alternative learning strategies.     

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.     

Strength-is-Weakness: The (ir)relevant relation between resources and payoffs in coalition formation

A key observation in coalition formation is that bargainers who control many resources are often excluded from coalitions by bargainers who control few resources, the Strength-is-Weakness effect. We argue that this effect is contingent on whether resources provide a legitimate claim to be included in a coalition. Across three incentivized coalition experiments (n = 2745; 915 triads), three participants (player A had four resources, player B had three resources, player C had two resources) negotiated about a payoff of 90 monetary units. Depending on condition, these resources were obtained randomly, earned, or earned and proportionally linked to the payoff. Results showed player As were less included when resources were obtained randomly and more often included in coalitions when resources were earned and/or proportionally linked to the payoff. This provides evidence that the Strength-is-Weakness is contingent on the legitimacy of the resources.     

Asymmetries between victims' and transgressors' perspectives following interpersonal transgressions

When interpersonal transgressions occur, the involved parties try to understand what occurred and how justice should be restored. However, research has documented that victims and transgressors often diverge in their accounts of what transpired. In this paper, I review and summarize empirical research on victims' and transgressors' asymmetric perceptions of interpersonal transgressions and the different justice‐restoring responses each party subsequently desires. By conceptualizing transgressions in terms of the social roles of victim and transgressor, I contend that justice responses can be thought of as attempts to correct inequitable distributions of material and symbolic resources. This social exchange perspective enables us to understand each party's motives and how various justice responses might satisfy them. I argue that because of these asymmetric perspectives, reconciliation is difficult, and conflict is liable to be perpetuated rather than resolved.     

The Price of the Calling: Exploring Clergy Compensation Using Current Population Survey Data

Previous research shows that clergy make less money than others with similar levels of education. We use Current Population Survey data to offer five contributions to knowledge about clergy compensation. First, we document and take into account the shift in clergy compensation from the provision of free housing to the payment of housing allowances. Second, although the clergy earnings disadvantage appears to have increased over the last 40 years relative to their educational peers, the picture changes when we exclude the highest income occupations. Clergy have lost ground to doctors, lawyers, and investment bankers, but they have gained ground relative to everyone else. Third, these gains are largely because of decline in the number of hours clergy report working. Fourth, we show that clergy working in churches earn less than clergy working elsewhere. Fifth, we document immediate wage penalties for those who become clergy and, among clergy, for those who begin to work in congregations. Overall, although clergy still earn less than comparable workers, their position has improved in recent decades relative to all but the highest earning occupations.     

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。     

Magnitudes of score differences produced within sessions in a cooperative exchange procedure

Interest centered on maximal score differences produced within sessions during two-party exchange. Subjects chose between earning money independently or through potentially higher-paying exchange. In the exchange option, only one person could produce points for the other on a trial. Because each exchange response (“give”) required the giver to forego earning points independently, the larger the score difference produced (i.e., the further ahead in earnings the other person was put), the greater the reduction in the giver's earnings if the other person did not reciprocate. Results showed that scores were usually equal at the end of each session, and that subjects maintained close equality of scores throughout each session. When a response-cost contingency that punished the alternation of giving was introduced, however, large within-session score differences developed. These large differences continued to be produced after the response-cost contingency was removed. Finally, when subjects were told that the session could end at any moment, score differences were sharply reduced, indicating that production of score differences remained under the control of discriminative stimuli associated with the likelihood of reciprocation. The study suggests that with appropriate procedures, an experimental analysis of behavioral phenomena associated with the concept of “trust” may be possible.
