Unequal but not separate: Emergence of rich–poor cooperation in resource exchange

Addressing inequality is a critical challenge for society as a whole and requires sustained efforts to promote fairness and opportunity for all. Filling in the resource gap across social classes is essential in reducing inequality. Previous studies have revealed that ingroup favouritism hinders the rich from cooperating with the poor and expands the wealth gap. Nevertheless, how to find ways of narrowing the gap between the rich and the poor remains an open question. Inducing rich–poor cooperation could be effective in eliciting resource flow across classes. In this study, two experiments using a modified Prisoner's Dilemma game were conducted in Japan (N = 213) and China (N = 150) to examine whether highlighting partners' cooperativeness under permeable group boundaries induces rich–poor cooperation. All participants were allocated to the rich group and participated in the game with programmed rich- or poor-group partner bots, whose cooperation rates were manipulated. Despite the initial resource disparities between participants and the partner bots, participants were more likely to select and cooperate with cooperative poor-group partners than with non-cooperative rich-group partners. Generalized trust played an important role in the enhancement of rich–poor cooperation. The findings shed light on the possibility of reducing inequality and promoting social mobility in society.

Mixture-modelling-based Bayesian MH-RM algorithm for the multidimensional 4PLM

Several recent works have tackled the estimation issue for the unidimensional four-parameter logistic model (4PLM). Despite these efforts, the issue remains a challenge for the multidimensional 4PLM (M4PLM). Fu et al. (2021) proposed a Gibbs sampler for the M4PLM, but it is time-consuming. In this paper, a mixture-modelling-based Bayesian MH-RM (MM-MH-RM) algorithm is proposed for the M4PLM to obtain the maximum a posteriori (MAP) estimates. In a comparison of the MM-MH-RM algorithm to the original MH-RM algorithm, two simulation studies and an empirical example demonstrated that the MM-MH-RM algorithm possessed the benefits of the mixture-modelling approach and could produce more robust estimates with guaranteed convergence rates and fast computation. The MATLAB codes for the MM-MH-RM algorithm are available in the online appendix.

Credentialism Across Creeds: Clergy Education and Stratification in Protestant Denominations

In this paper, we explore how Protestant denominations use education to stratify their pastors among lower and higher income jobs and how this use of education intersects with gender. We assume that reliance on education as anindication of job qualification ultimately reflects accommodation to secular norms and hypothesize that it will be practiced most strongly in theologically liberal contexts. Next, we hypothesize that women will benefit from education more than men, a pattern that is typical of secular labor markets. And we predict that education will have a stronger effect on income in denominations where regional clergy administrators have influence in matching pastors to jobs. Data are taken from the 1994 "Ordained Women and Men Study"and consist of career information on clergy in fifteen denominations. Contrary to expectations, clergy degrees have a stronger effect on income in conservative than in liberal denominations. We further find that women clergy receive lower income returns to their degrees in denominations requiring a Master of Divinity for ordination but receive higher returns in the others. Finally, results show that seminary prestige is more beneficial in denominations where pastors are hired directly by congregations rather than placed in congregations by regional clergy administrators.

Ambiguity Intolerance and Support for Valuing-Diversity Interventions

This study examined the effect of ambiguity intolerance on attitudes toward corporate diversity programs. It was found that, holding constant demographic backgrounds of age, gender, work experience, managerial position, and majority-minority status, ambiguity intolerance was negatively related to support for diversity programs. The study also replicated previous findings that women and racial minority members support diversity programs more than do men and racial majority members. This study demonstrates the importance of including personality variables in diversity research.     

小剂量吗啡对大鼠活动性的影响

腹腔注射不同剂量吗啡,观察各组大鼠在给药后不同时间的活动性（ｌｏｃｏｍｏｔｏｒａｃｔｉｖｉｔｙ,ＬＡ）,连续给药８天,每天给药后９５ｍｉｎ内,每间隔１５ｍｉｎ,记录大鼠５ｍｉｎ内在限定空间中所走格数。结果表明：随吗啡给药剂量或次数增加,ＬＡ呈升高趋势;使大鼠ＬＡ明显兴夯的适宜低剂量为４ｍｇ／ｋｇ／ｄａｙ,该剂量下每天药后１５－２０ｍｉｎＬＡ为峰值,而且此时段ＬＡ逐日升高,至第８日出现下降趋势,此毕     

Therapist Interventions Associated with Productive Emotional Processing in the Context of Attachment-Based Family Therapy for Depressed and Suicidal Adolescents

Productive emotional processing is considered a key change mechanism in attachment-based family therapy (ABFT). This study examined the impact of attachment-based family therapy therapist interventions aimed to promote productive emotional processing of primary adaptive emotions in a sample of 30 depressed and suicidal adolescents who had participated in a larger randomized clinical trial. Results of sequential analyses revealed that relational reframes and therapists’ focus on primary adaptive emotions were associated with the subsequent initiation of adolescents’ productive emotional processing of primary adaptive emotions. In contrast, interpretations, reassurances, and therapists’ focus on adolescents’ rejecting anger toward their parents were all followed by the discontinuation of adolescents’ emotional processing that had already begun. Finally, therapists’ general encouragement of affect and focus on adolescents’ unmet attachment/identity needs were associated with both the initiation of adolescents’ productive emotional processing, and with the discontinuation of such processing once it had already begun. Theoretical and clinical implications are discussed.     

“养中”与“格物”:蔡汝楠对王、湛之学的融通

甘泉学派是中晚明与阳明心学分庭抗礼的存在。两家虽然学术宗旨相异,但并非泾渭分明。不论阳明后学还是甘泉后学中,一直有主张融通的声音。本文以甘泉后学中以往学界缺乏研究的蔡汝楠为例,通过对其“养中”与“格物”观念的分析,探讨其对于王、湛两家之学的融通。在蔡汝楠看来,其“中”与“养中”的观念可以消解“良知”与“天理”之间的紧张,使得本体的主观性与客观性得到统一;其“格物”观则可以将“致良知”和“随处体认天理”统一起来,避免双方之间的彼此攻讦。从本文的分析可以看到,蔡汝楠的“养中”和“格物”,正是颇能体现其自觉融通王、湛两家思想的观念。
