消费者的归因对价格公平感和购买意愿的影响

采用实验情景模拟的方法,通过2X5的被试间设计,以712名被试作为研究对象,检验了在不同原因和不同商品涨价情景下消费者的价格公平感和购买意愿。在不提供涨价原因的情景下,被试的反应比较温和。根据归因理论,从控制点和可控性的维度区分了四种研究情景。结果发现,控制点和可控性之间的交互作用显著,控制点和商品种类的交互作用显著,消费者的消极情绪和对组织的评价在公平感与购买意愿之间具有部分中介效应。     

Motives and Likelihood of Bribery: An Experimental Study of Managers in Taiwan

Many studies of bribery acknowledge the important role of bribe-givers, but their true motives remain unclear. We propose that the likelihood of bribery depends on the willingness of an organization to affiliate with local parties or to be successful in a host country, or to have power over local parties. We further argue that different opportunities, either pervasive or arbitrary, facilitate different types of motives that affect the likelihood of bribery. In addition, we investigate the effect of perceived fairness on the likelihood of bribery. We employ a 3 (motives: affiliation vs. achievement vs. power)?×?2 (opportunities: pervasiveness vs. arbitrariness)?×?2 (perceived fairness: high vs. low) factorial design in experimental settings among Executive MBA students in southern Taiwan. Our findings indicate that, when companies perceive a higher level of distributive fairness, high-achieving organizations are more likely to offer a bribe when the condition is pervasive. When they have a powerful motive, arbitrariness engenders a higher likelihood of bribery. When they perceive less distributive fairness, there are no significant differences between motive and opportunity.     

Workplace fairness and emotional exhaustion in Nigeria police: The moderating role of gender

Abstract

This study examined the moderating role of gender in the relationship between perceived workplace fairness and reported level of emotional exhaustion among a sample of Nigeria police. A total of 214 participants took part in the cross-sectional survey. Results of the moderated hierarchical regression analysis provided support for gender as a moderating variable in the relationship between perceived workplace fairness and emotional exhaustion, such that perceived workplace fairness was a stronger predictor of emotional exhaustion among male police than for female police. The practical implications for the management of emotional exhaustion in general, and for the Nigeria police in particular, were emphasized.     

Can Competition Ever be Fair? Challenging the Standard Prejudice

In this paper, we challenge the usual argument which says that competition is a fair mechanism because it ranks individuals according to their relative preferences between effort and leisure. This argument, we claim, is very insufficient as a justification of fairness in competition, and we show that it does not stand up to scrutiny once various dynamic aspects of competition are taken into account. Once the sequential unfolding of competition is taken into account, competition turns out to be unfair even if the usual fairness argument is upheld. We distinguish between two notions of fairness, which we call U-fairness, where U stands for the usual fairness notion, and S-fairness, where S stands for the sequential aspect of competition. The sequential unfairness of competition, we argue, comprises two usually neglected aspects connected with losses of freedom: first of all, there is an eclipse of preferences in the sense that even perfectly calculating competitors do not carry out a trade-off between effort and ranking; and second, competitive dynamics leads to single-mindedness because the constraints on the competitors choices always operate in the sense of increased competitiveness and, therefore, in the direction of an increased effort requirements. We argue (1) that competition is S-unfair even if it is U-fair, (2) that as S-unfairness increases, the ethical relevance of U-fairness itself vanishes, so that (3) by focusing as they usually do on U-fairness alone, economists neglect a deeper aspect of unfairness.     

Unsignaled delay of reinforcement, relative time, and resistance to change

Two experiments with pigeons examined the effects of unsignaled, nonresetting delays of reinforcement on responding maintained by different reinforcement rates. In Experiment 1, 3-s unsignaled delays were introduced into each component of a multiple variable-interval (VI) 15-s VI 90-s VI 540-s schedule. When considered as a proportion of the preceding immediate reinforcement baseline, responding was decreased similarly for the three multiple-schedule components in both the first six and last six sessions of exposure to the delay. In addition, the relation between response rates and reinforcement rates was altered such that both parameters of the single-response version of the matching law (i.e., k and Re) were decreased. Experiment 2 examined the effects of unsignaled delays ranging from 0.5 s to 8.0 s on responding maintained by a multiple VI 20-s VI 120-s schedule of reinforcement. Response rates in both components increased with brief unsignaled delays and decreased with longer delays. As in Experiment 1, response rates as a proportion of baseline were affected similarly for the two components in both the first six and last six sessions of exposure to the delay. Unlike delays imposed between two stimulus events, the effects of delays between responses and reinforcers do not appear to be attenuated when the average time between reinforcers is longer. In addition, the disruptions produced by unsignaled delays appear to be inconsistent with the general finding that responding maintained by higher rates of reinforcement is less resistant to change.     

Rawls and Research on Cognitively Impaired Patients: A Reply to Maio

In his paper, “The Relevance of Rawls’ Principle of Justice for Research on Cognitively Impaired Patients” (Theoretical Medicine and Bioethics 23 (2002):45–53), Giovanni Maio has developed athought-provoking argument for the permissibility of non-therapeutic research on cognitively impaired patients. Maio argues that his conclusion follows from the acceptance of John Rawls’s principles of justice, specifically, Rawls’s “liberty principle” Maio has misinterpreted Rawls’s “libertyprinciple” – correctly interpreted it does notsupport non-therapeutic research on cognitivelyimpaired patients. Three other ‘Rawlsian’ arguments are suggested by Maio’s discussion –two “self-respect” arguments and a “presumed consent” argument – but none of them are convincing. However, an alternative argument developed from Rawls’s discussion of “justice in health care” in his most recent book, Justice as Fairness: A Restatement, may justify certain kinds of non-therapeutic research on some cognitively impaired patients in special circumstances. We should not expect anything more permissive from a liberal theory of justice. This revised version was published online in June 2006 with corrections to the Cover Date.     

Examining the between- and within-person effects of relative deprivation: Results from a 7-year longitudinal panel sample

Despite the extensive literature on relative deprivation theory, few studies have examined the longitudinal effects of individual- and group-based relative deprivation (IRD and GRD, respectively) on individual- and group-based outcomes, nor has research investigated the between-person and within-person effects of these constructs. Using two random intercept cross-lagged panel models, we address these oversights by estimating the between-person and average annual within-person associations IRD and GRD have with psychological distress and collective action support in a nation-wide longitudinal panel sample (N = 64,607). As expected, IRD and GRD were more strongly associated with psychological distress and collective action support, respectively, at the between-person level and contemporaneously at the within-person level. However, contrary to expectations, temporary departures in IRD and GRD predicted within-person increases in collective action support and psychological distress, respectively. These results raise questions about how and when people respond to inequality and provide the foundations for future longitudinal research.     

Oral self-administration of pentobarbital by rhesus monkeys: relative reinforcing effects under concurrent fixed-ratio schedules.

During daily 3-hr sessions, orally delivered pentobarbital solutions and water, or two separate pentobarbital solutions, were concurrently available to rhesus monkeys according to fixed-ratio schedules of mouth contacts with a spout. First water, and then each of four "comparison-concentration" pentobarbital solutions (0.0625, 0.25, 1, and 4 mg/mL), was successively available from one spout for a block of sessions under a fixed-ratio-64 (three monkeys) or fixed-ratio-16 (one monkey) schedule. Under an identically sized fixed-ratio schedule, deliveries of a "standard-concentration" pentobarbital solution were concurrently available from a second spout. The concentration of the standard solution remained unchanged throughout testing of the series of comparison solutions. Each of three pentobarbital concentrations (4, 1, and 0.25 mg/mL) in turn served as the standard concentration. Within each pair of concurrently available solutions, the higher drug concentration maintained more behavior than the lower concentration. Thus when monkeys were provided with concurrent access to different pentobarbital concentrations, relative reinforcing effects were directly related to drug concentration. Further, the amount of behavior maintained by a particular drug concentration was dependent on the concentration of the concurrently available drug solution. Thus, the relative effectiveness of a reinforcer in maintaining behavior is a function of both the reinforcer's magnitude and the availability of alternative reinforcers in the environment.     

恒河猴对50以下数目的估计

本研究有６个从易到难的程序,每个程序有标准数目和比较数目,都是白卡片上的黑圆点。每次试验先呈现标准数目作为样本,强化后撤去,随后同时呈现标准数目和比较数目,令动物作二择一反应。实验结果表明,影响恒河猴数目估计的有两个主要因素,即标准数目和比较数目之间的数间距和这两个数目本身的大小。在数间距为４或大于４时,恒河猴能对５０以下的数作出估计;在数间距为２时,恒河猴能对９－２５的数作出估计,但不能对２７－４９的数作估计。作者以为,这里所进行的是一种相对的区域性的数目估计,但它仍然是一种数标签的过程。
