On Moderate Pluralism About Truth and Logic

According to moderate truth pluralism, truth is both One and Many. There is a single truth property that applies across all truth-apt domains of discourse, but instances of this property are grounded in different ways. Propositions concerning medium-sized dry goods might be true in virtue of corresponding with reality while propositions pertaining to the law might be true in virtue of cohering with the body of law. Moderate truth pluralists must answer two questions concerning logic: (Q1) Which logic governs inferences concerning each truth-apt domain considered separately? (Q2) Which logic governs inferences that involve several truth-apt domains? This paper has three objectives. The first objective is to present and explain the moderate pluralist’s answers to (Q1) and (Q2). The second objective is to argue that there is a tension between these answers. The answer to (Q1) involves a commitment to a form of logical pluralism. However, reflection on the moderate truth pluralist’s answer to (Q2) shows that they are committed to taking logic to be topic neutrality. This, in turn, forces a commitment to logical monism. It would seem that the moderate truth pluralist cannot have it both ways. The third objective is constructive in nature. I offer an account of what moderate truth pluralists should say about logic and how they might resolve the tension in their view. I suggest that, just like moderate truth pluralists distinguish truth proper and “quasi-truth,” they should endorse a distinction between logic proper and “quasi-logic.” Quasi-truth is truth-like in the sense that instances of quasi-truth ground instances of truth. Quasi-logic is logic-like in the sense that it concerns arguments that are necessarily truth-preserving but are not generally so in a topic neutral way. I suggest that moderate truth pluralists should be monists about truth proper and logic proper but pluralists about quasi-truth and quasi-logic. This allows them to say that logic proper is topic neutral while still accommodating the idea that, for different domains, different arguments may be necessarily truth-preserving.     

The role of storytelling in advertising: Consumer emotion,narrative engagement level,and word‐of‐mouth intention

This experimental study with a national online sample (n = 300) tested the effects of storytelling in radio advertisements on participants' positive emotional responses and intentions to share information about the product, depending on audiences' narrative engagement level. Treatments included a commercial for a fictitious brand of luggage using a story told by the founder of the company, another version of the same commercial manipulated so the speaker was a customer of the company, and a control stimulus consisting only of information about the product. Results showed that narrative transportation and narrative preference are positively associated with favorable responses toward ad. Stories elicited more favorable emotional responses and had some effect on participants' intention to share information about the product by word‐of‐mouth. This was especially true among participants hearing the founder's story. Results support previous assumptions about the power of storytelling in advertising, including distinctions regarding the identity of the speaker (founder vs. customer).     

流动儿童同伴侵害的特点及与内化问题的循环作用关系:一项追踪研究

本研究采用纵向设计,以北京市426名四、五年级流动儿童为被试,进行连续4次的追踪测查,考察流动儿童同伴侵害的特点及其与内化问题的动态相互作用关系。结果发现:(1)打工子弟学校流动儿童的同伴侵害与内化问题水平比公立学校流动儿童高;流动儿童的流动性越大,同伴侵害和内化问题越多。(2)控制了性别、年级、家庭社会经济地位(SES)和流动性后,从T1到T2,同伴侵害与孤独感为相互作用关系,且同伴侵害可以显著预测抑郁,但对社交焦虑的预测作用不显著,而从T2到T4,同伴侵害和3种内化问题的相互作用模式完全一致,即T2时的社交焦虑、抑郁和孤独感显著预测T3的同伴侵害,进而显著预测T4的社交焦虑、抑郁和孤独感。(3)抑郁、孤独感与同伴侵害的循环作用在两类流动儿童中具有较强的稳定性,而在社交焦虑和同伴侵害的模型中,打工子弟学校流动儿童的同伴侵害对社交焦虑的作用比公立学校流动儿童更大。可见,同伴侵害和内化问题呈循环作用关系,未来预防/干预研究可以聚焦于减少流动儿童的同伴侵害或内化问题的角度打破二者的恶性循环,帮助他们建立良好的人际关系,构建良性循环,促进他们的积极发展。     

A Case Study of Solution-Focused Brief Family Therapy

Abstract

Solution-focused brief therapy (SFBT) was developed as a form of family therapy. Recently, these features have blurred. This case study explores how Insoo Kim Berg interacts with multiple family members in SFBT. The results indicate that she used a circular procedure to ensure that all the family members were involved in the process. The analysis demonstrates the importance of purposeful use of language and the influence of systems theory in SFBT. SFBT provides a useful framework that enables a family therapist to work together with families to help them make the changes they want with their own strengths and resources.

"脑死亡=死亡"生物医学定律的逻辑论证

心脏具有顽固自律性、可多次复苏性、功能可人工替代性、可多次置换性四大特点,因而已失去作为死亡判定权威器官的地位.而大脑由于具有统领性、损坏后不可恢复性、功能不可替代性、全脑不可置换性四大特点,已替代心脏成为死亡判定的靶器官."脑死亡=死亡"在相当长时期内都将是一个严格的科学定义.     

Self‐tracking in effortful activities: Gender differences in consumers' task experience

Despite the increasing use of self‐tracking technologies, surprisingly little empirical research has examined the effect of self‐tracking in effortful activities on consumers' task experience. Accordingly, the present research examined the moderating role of gender in the effect of self‐tracking in effortful activities on perceived competence and task experience (namely, enjoyment and subjective vitality). Across three experiments, results suggested that self‐tracking in effortful activities increases the perceived competence, enjoyment, and subjective vitality of females more than males, and that perceived competence explains these interaction effects. Interestingly, an experimental manipulation designed to prompt overestimation of abilities attenuated these positive effects among females. As such, the present research contributes to the literatures on self‐tracking and feedback instrumentality, and offers important practical implications for marketers.     

Selecting polychoric instrumental variables in confirmatory factor analysis: An alternative specification test and effects of instrumental variables

The polychoric instrumental variable (PIV) approach is a recently proposed method to fit a confirmatory factor analysis model with ordinal data. In this paper, we first examine the small-sample properties of the specification tests for testing the validity of instrumental variables (IVs). Second, we investigate the effects of using different numbers of IVs. Our results show that specification tests derived for continuous data are extremely oversized at all sample sizes when applied to ordinal variables. Possible modifications for ordinal data are proposed in the present study. Simulation results show that the modified specification tests with all available IVs are able to detect model misspecification. In terms of estimation accuracy, the PIV approach where the IVs outnumber the endogenous variables by one produces a lower bias but a higher variation than the PIV approach with more IVs for correctly specified factor loadings at small samples.     

推类等于类比推理吗？

近10年来,中国古代的推类理论被普遍认为有助于说明中国古代逻辑与西方（亚里士多德）逻辑的不同。关于推类的逻辑本质——推类的前提与结论之间究竟是何种推理关系,一种流行的观点是将推类与类比推理等而视之。不过,伍非百、汪奠基、沈有鼎、刘培育、孙中原等对类同原则的适用范围与推类的逻辑本质做了更为全面与准确的诠释。通过分析中国古代的推类实践,可以从中揭示出类同原则的工作机制,从而在经验层面上进一步确认类同原则对于演绎、归纳和类比推理的普遍意义,最终证成推类与类比推理并不等同。     

Religious Involvement and Dynamics of Marijuana Use: Initiation,Persistence, and Desistence

Studies that examine the effects of adolescent religiosity on the initiation of, persistence in, and desistence from delinquency are rare. Yet, religion may differentially affect dimensions of delinquency in the early life course. Therefore, using data from the National Longitudinal Study of Adolescent Health (Add Health), we examine the relationship between measures of adolescent religion, as well as changes in religious involvement, and later patterns of marijuana use. We also examine the extent to which religious effects, if any, are mediated by key predictors of delinquency drawn from prominent criminological theories. The results suggest that the primary effect of religion on marijuana use is to prevent its initiation in the first place. Only part of religion's preventative effect on initiation is mediated by social bonds, delinquent peers, or self control. Although religious youth are less likely to ever use marijuana, adolescent religious involvement does not significantly predict desistence from marijuana use.
