Compromised item detection: A Bayesian change-point perspective

Psychometric methods for accurate and timely detection of item compromise have been a long-standing topic. While Bayesian methods can incorporate prior knowledge or expert inputs as additional information for item compromise detection, they have not been employed in item compromise detection itself. The current study proposes a two-phase Bayesian change-point framework for both stationary and real-time detection of changes in each item's compromise status. In Phase I, a stationary Bayesian change-point model for compromise detection is fitted to the observed responses over a specified time-frame. The model produces parameter estimates for the change-point of each item from uncompromised to compromised, as well as structural parameters accounting for the post-change response distribution. Using the post-change model identified in Phase I, the Shiryaev procedure for sequential testing is employed in Phase II for real-time monitoring of item compromise. The proposed methods are evaluated in terms of parameter recovery, detection accuracy, and detection efficiency under various simulation conditions and in a real data example. The proposed method also showed superior detection accuracy and efficiency compared to the cumulative sum procedure.     

Permitting immoral behaviour: A generalized compensation belief hypothesis

When are we more likely to permit immoral behaviours? The current research examined a generalized compensation belief hypothesis that individuals, as observers, would morally tolerate and accept someone paying forward unfair treatment to an innocent person as a means to compensate for the perpetrator's previously experienced mistreatment. Across five experiments (N = 1107) based on economic games (Studies 1–4) and diverse real-life scenarios (Study 5), we showed that participants, as observing third parties, were more likely to morally permit and engage in the same negative act once they knew about previous maltreatment of the perpetrator. This belief occurred even when the content of received and paid-forward maltreatment was non-identical (Study 2), when the negative treatment was received from a non-human target (Study 3) and when the maltreatment was intangible (e.g. material loss) or relational (e.g. social exclusion; Study 5). Perceived required compensation mediated the effect of previous maltreatment on moral permission (Studies 4 and 5). The results consistently suggest that people's moral permission of immoral behaviours is influenced by perpetrator's previous mistreatment, contributing to a better understanding of the nature and nuances of our sense of fairness and contextualized moral judgement.     

A postcolonial Pannenberg? Mimicry,the law,and the cross of love

This paper employs the postcolonial concepts of mimicry and hybridity to interpret Wolfhart Pannenberg's understanding of the violence done to Jesus on the cross and the subversive reconciliatory love that it engenders. According to Pannenberg, although the man Jesus was crucified as blasphemer of the Jewish law, the resurrection vindicated Jesus so that the ones accusing Jesus were retroactively deemed to be the actual blasphemers. As a result, Jesus ended up dying not for his own alleged breaking of the law, but as an inclusive substitute for all blasphemers of God (through amour propre) deserving death. Thus, the resurrection confirmed Jesus’ divine identity and his earthly teaching that love supersedes and transforms the law. Applying the concept of mimicry to Pannenberg, on the cross the symbolic and semiotic are held together in tension for in mimicry the “not-quite sameness” menaces the colonizer. The cross, ostensibly a symbolic sign of abjection, is mimicked by the suffering of Jesus and subverted through a practice of inclusive semiotic love which recapitulates sinful human life toward a life of transformed autonomy. Pannenberg displays a pseudo postcolonial understanding of subverting oppressive law into love. However, on account of his futurist ontology, the eschatological totality is underscored relative to formative experiences, leaving him vulnerable to postcolonial critiques of essentialism, which can reinscribe colonialism. I contend that Pannenberg employs a strategy of “strategic particularism” in which concepts such as mimicry and hybridity are helpful as hermeneutical tools but ultimately provisional and temporary relative to the whole.     

Measuring Religiosity of East Asians: Multiple Religious Belonging,Believing, and Practicing

Social surveys normally assume that respondents adhere to a single religious faith in belonging, believing, and practicing congruently. Some surveys even take religious identity as the singular measure of religiosity and examine its relationship with other variables. This practice, however, fails to capture nonexclusive and hybrid religiosity, which is arguably the traditional and normal pattern in East Asia while becoming increasingly common in the West. We have developed a new set of survey questions and conducted a survey among East Asian international students at an American university. The findings show that multiple religious belonging, believing, and practicing are quite common, the level of believing and participating in religions varies substantially, and no confession-based single measure of religious identity or practice is sufficient for measuring religiosity. We recommend this set of improved measures of religiosity be adopted in future surveys in East Asia and probably in the West as well.     

Experiencing Buddhist practices promotes nonbelievers’ preference for future rewards in intertemporal choices

Religious individuals often prefer future rewards more in intertemporal decision-making than nonreligious individuals, but the reasons behind this preference remain under-investigated. Focusing on decision-making in Buddhist culture, the current study aimed to examine three potential mechanisms: Buddhist practices, self-control and belief in future-oriented concepts. In five studies, we consistently found that nonbelievers’ preference ratings for Larger and Later (LL) options increased after visiting a temple (Study 1, n = 99) or participating in Buddha name chanting (Studies 2–5, n = 314). We also found in Studies 3 and 4 that this effect was mediated by the individual's level of self-control, but no evidence was found to support the mediation of belief in future-oriented concepts. These results contribute to the work attesting to the effect of religious practices on individuals (especially nonbelievers). They also provide a mechanism (self-control) for the positive correlation between individuals’ religiousness and preference for future rewards in intertemporal decision-making.     

Cross-cultural Differences in Self-reported Decision-making Style and Confidence

The Melbourne Decision Making Questionnaire (Mann, Burnett, Radford, & Ford, 1997) measures self-reported decision-making coping patterns. The questionnaire was administered to samples of University students in the US (N = 475), Australia (N = 262), New Zealand (N = 260), Japan (N = 359), Hong Kong (N = 281), and Taiwan (N = 414). As predicted, students from the three Western, individualistic cultures (US, Australia, and New Zealand) were more confident of their decision-making ability than students from the three East Asian, group-oriented cultures (Japan, Hong Kong, Taiwan). No cross-cultural differences were found in scores on decision vigilance (a careful decision-making style). However, compared with Western students, the Asian students tended to score higher on buck-passing and procrastination (avoidant styles of decision making) as well as hypervigilance (a panicky style of decision making). Japanese students scored lowest on decision self-esteem and highest on procrastination and hypervigilance. It was argued that the conflict model and its attendant coping patterns is relevant for describing and comparing decision making in both Western and Asian cultures.

Beyond Distributive Justice: The Reasonableness Norm in Chinese Reward Allocation

Western theorists have generally construed reward allocation as mainly a rational action by the notion that allocation decision-making is based solely on people's justice concern. We argued that reward allocation, as a social act taking place in a specific social-situational context, is influenced both by some social interactive factors such as the relationship and social interactions between the participants, and by the pervasive social norms governing people's conduct in a particular society. This study aimed at examining the influence of two such factors, guanxi (equivalent to relationship) and renqing (equivalent to human affect), on Chinese allocation decision-making under a distributive situation. We hypothesized that Chinese allocators would base their decision not only on their judgment of the participants' contributions but also on their guanxi with the participant. Specifically, we predicted that the emphasis on guanxi and renqing would be manifested in the Chinese allocator's employment of the reasonableness norm dictating that both reason ( li ) and affect ( qing ) are considered in making allocation decisions. To test this hypothesis, we adopted the scenario approach and asked subjects to hypothetically allocate a reward to one of six guanxi partners. The 228 participants were divided into six groups; in each group they were instructed to do the allocation based on one of the five norms respectively: fairness ( he li ), renqing , equity ( gong zheng ), "ought to," reasonableness ( he qing he li ), and to indicate what they "would" allocate. The findings confirmed that the reasonableness norm was the one which subjects adopted in reward allocation. The results were discussed in the context of Chinese culture.
