马克思博士论文的政治伦理向度——兼论其与近代契约论的关联

马克思的博士论文蕴涵着深刻的政治伦理意蕴,他关于德谟克利特的自然哲学与伊壁鸠鲁的自然哲学的差别的论述,表明了其对人的主体性的高扬;他对原子偏斜运动的论述,表明了其对自由的诉求;他对原子排斥运动的论述,表明了其对平等的关注.这些思想与近代契约论有许多相通之处,但是它并不是对近代契约论的翻版,它关于人的思想、关于自由与平等的观念的理解与近代契约论有着显著的区别,而这正是其对近代契约论的超越之处.     

西方公民观与公民道德观的历史演变——从古希腊罗马时期至17、18世纪

古希腊罗马时期的公民是享有政治和经济特权的少数人 ,智慧、勇敢、节制和正义是公民应具备的“四主德” ;中世纪缺乏公民与公民道德生长的土壤 ,社会造就的是谦卑温顺的臣民及深受基督教神学影响的臣民道德 ;17、18世纪的公民理论突破了古希腊罗马时期公民资格的狭隘性 ,公民的内涵大大拓展 ,资产阶级思想家们提出了与资本主义发展相适应的公民道德 ,但资产阶级公民道德理论也具有一定的虚伪性。     

Epigenetic regulation of reelin and brain-derived neurotrophic factor genes in long-term potentiation in rat medial prefrontal cortex

Epigenetic mechanisms have recently been known to play fundamental roles in the regulation of synaptic plasticity, and learning and memory tasks in many brain regions, such as the hippocampus, the amygdala, the insular cortex. However, epigenetic mechanism in the medial prefrontal cortex (mPFC), also a crucial neural locus for the control of cognition and emotion, is not well known. The present study investigated the epigenetic regulation of two genes, reelin and brain-derived neurotrophic factor (bdnf), both play important roles in neural plasticity, in the mPFC. The data showed that the levels of total DNA methyltransferase (DNMTs), total histone acetyltransferases (HATs), global acetylated histone 3 (H3) and global acetylated histone 4 (H4) were all changed with the induction of long-term potentiation (LTP) in the mPFC, implying that DNA methylation and histone acetylation may involve in synaptic plasticity in the mPFC. The present results further demonstrated that the demethylation status of reelin and bdnf, and acetylated H3 and acetylated H4 at the reelin and the bdnf promoters in the mPFC were enhanced by the delivery of LTP-inducing high-frequency stimulation (HFS). Consistently, infusion of DNMT inhibitor, 5-azacytidine (5-azaC), or histone deacetylases (HDACs) inhibitor, sodium butyrate (NaB), into the mPFC could interfere with LTP-associated demethylation and acetylation of reelin and bdnf genes, and the induction of LTP as well. Long-term retention of trace fear memory, which is dependent on mPFC function, was also altered by administration of these inhibitors into the mPFC. These findings suggest that epigenetic regulation of DNA demethylation and histone acetylation of target genes, such as reelin and bdnf, might underlie the mechanisms of synaptic plasticity and memory retention in the mPFC.     

Semantic games with chance moves revisited: from IF logic to partial logic

We associate the semantic game with chance moves conceived by Blinov with Blamey’s partial logic. We give some equivalent alternatives to the semantic game, some of which are with a third player, borrowing the idea of introducing the pseudo-player called Nature in game theory. We observe that IF propositional logic proposed by Sandu and Pietarinen can be equivalently translated to partial logic, which implies that imperfect information may not be necessary for IF propositional logic. We also indicate that some independent quantifiers can be regarded as dependent quantifiers of indeterminate sequence, using the interjunction connective in partial logic. We conclude our paper by indicating some further research in a more general setting.     

Effects of Gendered Language on Gender Stereotyping in Computer‐Mediated Communication: The Moderating Role of Depersonalization and Gender‐Role Orientation

This experiment examined what situational and dispositional features moderate the effects of linguistic gender cues on gender stereotyping in anonymous, text‐based computer‐mediated communication. Participants played a trivia game with an ostensible partner via computer, whose comments represented either prototypically masculine or feminine language styles. Consistent with the social identity model of deindividuation effects, those who did not exchange brief personal profiles with their partner (i.e., depersonalization) were more likely to infer their partner’s gender from the language cues than those who did. Depersonalization, however, facilitated stereotype‐consistent conformity behaviors only among gender‐typed individuals; that is, participants conformed more to their masculine‐ than feminine‐comment partners, and men were less conforming than were women, only when they were both gender‐typed and depersonalized.     

The possible selves of international students and their cross‐cultural adjustment in Canada

We assessed 93 international students’ reports of their expected and feared possible selves in terms of their thematic content and configuration, and examined the relations between possible selves and cultural adjustment in Canada. The results showed that international students mostly envisioned possible selves in career, education, intrapersonal, and interpersonal domains, and reported more balanced configurations than matched configurations of possible selves. Balanced possible selves in the educational domain were associated with better psychological well‐being, but balanced selves in the intrapersonal domains were linked with more frequent sociocultural difficulties. The findings suggest that the content of international students’ possible selves reflects not only their academic‐focused and career‐inspired sojourn, but also their intercultural experiences with various ethnic groups in the Canadian multicultural society. As well, they speak to the motivational significance of possible selves, particularly the balanced possible selves, for supporting international students’ motivation to pursue an international education and for facilitating a successful cross‐cultural sojourn.     

Is compatibilism intuitive?

Eddy Nahmias, with various collaborators, has used experimental data to argue for the claim that folk intuition is generally compatibilist. We try to undermine this claim in two ways. First, we argue that the various formulations of determinism he uses are not conceptually equivalent, jeopardizing the kinds of conclusions that can be drawn from the resulting data. Second, prompted by these conceptual worries we supplement the typical quantitative surveys that dominate the extant literature with short qualitative interviews. This, in turn, guides us to make a minor modification to the quantitative survey that provides better access to the relevant folk intuitions.     

9～11岁儿童对失败学习情景的情绪反应和情绪表达研究

本研究对180名9-11岁儿童在失败学习情景下的情绪反应和情绪表达进行了研究。结果表明：(1)儿童在失败学习情景中情绪表达的意愿受年龄影响。(2)儿童在失败学习情景中的情绪表达原因受年龄和观众背景影响。儿童隐藏情绪的原因主要是害怕消极的后果,表达情绪的原因是为了得到积极的结果。(3)儿童在失败学习情景中情绪表达和隐藏的策略受年龄、性别和观众背景的影响。(4)儿童的后继行为受年龄的影响。     

社会合作信息对距离知觉的影响

为探讨社会合作信息对距离知觉的影响,本研究通过两个实验,采用动态追逐场景,对两个追逐者之间的交互模式(或合作或单独追逐同一目标)与追逐目标的存在与否进行了操作。结果发现,相比随机运动和单独追逐,存在合作关系的两个追逐者间的距离被知觉得更远,即存在距离的扩张效应(实验1),且该效应不能由底层的物理特征所解释(实验2)。该结果揭示,社会合作信息使得知觉距离被扩张,其可帮助理解视觉的适应性机制。     

Appealing to Gen Z with Mother Nature for sustainable consumption: With mediation of psychological closeness to nature and consequence of psychological well-being

Although Gen Z consumers show greater concern about sustainability than other generational cohorts, specific investigations into their sustainable consumption regarding their perceptions towards nature are relatively understudied. To address this gap, this research examines the way Gen Z consumers view nature and engage in sustainable consumption. Through a cross-sectional survey in the U.S., the study finds that the individual tendency to anthropomorphize nature contributes to shaping psychological closeness to nature. Furthermore, nature anthropomorphism enhances sustainable consumption, and this is mediated by consumer perception of psychological closeness to nature. Additionally, sustainable consumption leads to psychological well-being. These findings highlight that the extent to which Gen Z consumers find humanness in nature contributes to sustainable consumption by enhancing a feeling of being close to nature and this process results in the enhancement of psychological well-being. Theoretical and practical implications are discussed.
