Axiomatizing hybrid products: How can we reason many-dimensionally in hybrid logic?

The aim of this paper is to propose a two-dimensional hybrid logic in order to formalize inferences containing both spatial and temporal propositions. The semantic idea behind the proposal is to name both horizontal and vertical lines in a 2D-plane by two kinds of nominals. This is a generalization of the idea of naming a point in one-dimensional hybrid logic. I give an axiomatization of the proposed two-dimensional hybrid logic and show that it enjoys a general completeness result (called pure completeness) with respect to product Kripke frames. Moreover, in order to capture $T\times W$-frames studied by R.H. Thomason (1984), I introduce the notion of a dependent product frame, which enables us to represent the dependence of space over time. I also give a complete axiomatization of this dependent two-dimensional hybrid logic, and, as a corollary, reveal that a hybridization of $T\times W$-logic enjoys strong completeness.     

Modal Platonism: an Easy Way to Avoid Ontological Commitment to Abstract Entities

Modal Platonism utilizes “weak” logical possibility, such that it is logically possible there are abstract entities, and logically possible there are none. Modal Platonism also utilizes a non-indexical actuality operator. Modal Platonism is the EASY WAY, neither reductionist nor eliminativist, but embracing the Platonistic language of abstract entities while eliminating ontological commitment to them. STATEMENT OF MODAL PLATONISM. Any consistent statement B ontologically committed to abstract entities may be replaced by an empirically equivalent modalization, MOD(B), not so ontologically committed. This equivalence is provable using Modal/Actuality Logic S5@. Let MAX be a strong set theory with individuals. Then the following Schematic Bombshell Result (SBR) can be shown: MAX logically yields [T is true if and only if MOD(T) is true], for scientific theories T. The proof utilizes Stephen Neale’s clever model-theoretic interpretation of Quantified Lewis S5, which I extend to S5@.     

初级运动区的fMRI实验研究

本实验采用功能磁共振为实验仪器,被试进行运动准备和运动执行两种作业活动,实验设计为延时序列运动任务。在对实验数据进行预处理,反卷积、标准化处理后,采用欧式距离公式进行聚类统计,统计结果显示,M1区不仅具有运动执行和运动准备的功能,还发现其他功能区域的激活,不是单纯的运动执行功能,这一区域与三种活动有关。     

幼儿箱庭基本特征的初步研究

研究选取了10名幼儿（3～6岁）,对他们的初次箱庭的基本特征进行研究,结果如下：给幼儿介绍箱庭时通常需要他们的父母或朋友在场,利用玩具在引导幼儿熟悉箱庭时发挥重要作用;幼儿箱庭制作时间都比较长;玩具选择以动物类为主;制作过程中频繁移动玩县;空间使用以“占满”类型为主;大多数幼儿制作时都不动沙;作品主题以“无明确主题”为主,有明确主题的主要为“动物世界类”和“家庭生活类”;制作过程中幼儿主动与见证人之间的互动频繁。     

刺激放置朝向对返回抑制的影响:一项ERPs研究

返回抑制(inhibition of return, IOR)是指个体对出现在先前提示位置上的刺激反应更慢的现象。尽管大量ERPs研究发现呈现在线索化和非线索化位置上的靶刺激诱发的ERPs在250-300ms处存在一个稳定的差异(Nd250),但这一差异的方向却并不一致。本研究采用事件相关电位技术(Event-related Potentials, ERPs),结合经典的线索-靶子范式,考察刺激放置的朝向是否会影响到IOR中Nd250效应的极性。结果显示虽然刺激放置朝向并未有影响到Nd250的极性,却对早期P1成分的线索化效应的地形图分布有着显著的影响。这表明1）过往ERPs研究中的Nd250效应极性的不一致并非源于刺激放置朝向的作用;2）刺激的放置朝向会导致早期线索化效应(P1)在地形分布上出现差异。     

Irrational beliefs and unconditional self-acceptance. I. Correlational evidence linking two key features of REBT

In a study with 102 non-clinical adults, relationships between measures of irrational beliefs, unconditional self-acceptance, self-esteem and the Big-5 personality dimensions were investigated. As expected, unconditional self-acceptance was highly correlated with self-esteem. In line with key tenets of REBT, individuals who scored highly on unconditional self-acceptance scored low on irrational beliefs even after self-esteem had been partialled out. Unconditional self-acceptance was found to be significantly (negatively) correlated with Neuroticism but not with other Big-5 personality dimensions. Irrational beliefs were found to correlate positively with Neuroticism and negatively with Openness. Factor analysis of the unconditional self-acceptance scale did not show a simple one-dimensional structure. A revised version of the scale comprising those items that did not load on a self-esteem factor produced a purer measure of unconditional self-acceptance that did not correlate significantly with self-esteem. The findings have implications for investigating unconditional self-acceptance in studies of therapeutic outcome.     

Sexual well-being and perceived stress in couples transitioning to parenthood: A dyadic analysis

Background/ObjectiveThe transition to parenthood encompasses several psychological and relational changes that might contribute to couples’ high levels of stress postpartum. Although common across the postpartum, couples’ sexual changes are frequently overlooked.MethodWe surveyed 255 mixed-sex new parent couples to examine the associations between sexual well-being—sexual satisfaction, desire, and postpartum sexual concerns—and perceived stress postpartum. Couples completed self-report questionnaires assessing perceived stress and sexual well-being.ResultsFor both mothers and fathers, greater sexual satisfaction was associated with their partners’ lower perceived stress and, for fathers, this was also associated with their own lower perceived stress. For mothers, greater partner-focused sexual desire was associated with their own lower perceived stress whereas, for fathers, greater partner-focused sexual desire was associated with their partners’ higher perceived stress. In addition, greater solitary sexual desire and postpartum sexual concerns were associated with both parents’ own higher perceived stress.ConclusionsThis study highlights the association between sexual well-being and couples’ postpartum stress, suggesting that more positive sexual experiences are linked to lower perceptions of stress across this vulnerable period. Couples’ sexual well-being may be an important target for interventions aimed at helping postpartum couples cope with stress.     

Prosody instruction intervention as a means to improved reading comprehension

The relationship between prosody and comprehension, previously demonstrated in K–12 students, was examined in university students enrolled in first‐year writing classes. Students completed the Gray Oral Reading Test‐5 both before and after an expressive reading intervention (ER) or no oral reading instruction (NI). Throughout the semester, the ER students marked an excerpt of text for prosodic signals and read it aloud with a partner. Training and practice in expressive reading led to a significant improvement in the normed Oral Reading Index score. Specifically, ER participants demonstrated improved accuracy, fluency, and reading comprehension in comparison with NI participants. The significant relationship between accuracy and comprehension in the ER condition suggests that expressive reading instruction strengthened student ability to read words accurately and, in turn, comprehend the material better than students in the NI condition. Expressive reading practices are recommended to engage students more deeply with the text.
