北京都城隍庙考

北京都城隍庙始建于元,迄今730余年.随着时局的变迁,如今的都城隍庙只有后殿"寝祠"幸存,旧日恢弘的建筑、庄严的祭礼,以及商贾云集的庙市早已淡出了人们的记忆.本文试图对都城隍庙从多个角度进行考证梳理,力求建立起一个对都城隍庙进行整体认知的构架.     

Gender Differences in the Relationships between Parental Marital Conflict,Differentiation from the Family of Origin,and Children’s Marital Stability

Abstract

This study aimed to examine gender differences in the relationships between parental marital conflict, differentiation from the family of origin, and children’s martial stability. Data were collected from 453 married individuals in South Korea. The results revealed that parental marital conflict was directly related to children’s marital stability albeit only among married men. Emotional cutoff and family projection mediated the relationship between parental marital conflict and children’s marital stability among men and women, respectively. These findings can be used to develop gender-specific evidence-based interventions that enhance marital stability (e.g., programs for married and premarital couples).     

Attentional bias toward waiting time information among individuals with high and low trait self-control when making intertemporal choices

ABSTRACT

The present study aimed to explore whether the modulation effects of attentional biases toward time information representing immediate rewards and delayed rewards differ between individuals with high and low trait self-control. Forty participants with high trait self-control and 40 with low trait self-control were selected based on their responses to the Chinese version of the self-control scale, and they were asked to complete an intertemporal choice task and dot probe task first and then a cue-target task a week later. The results showed that the participants with low trait self-control were more likely to choose immediate rewards than participants with high trait self-control. Furthermore, facilitated attention and difficulty in attention disengagement toward present-related words were found among participants with low trait self-control with higher frequency than among those with high trait self-control. Finally, facilitated attention toward present-related words moderated the indifference points among the participants with low trait self-control.     

Possible novel features of synaptic regulation during long-term facilitation in Aplysia

Most studies of molecular mechanisms of synaptic plasticity have focused on the sequence of changes either at individual synapses or in the cell nucleus. However, studies of long-term facilitation at Aplysia sensory neuron–motor neuron synapses in isolated cell culture suggest two additional features of facilitation. First, that there is also regulation of the number of synaptic contacts between two neurons, which may occur at the level of cell pair-specific branch points in the neuronal arbor. Branch points contain many molecules that are involved in protein synthesis-dependent long-term facilitation including neurotrophins and the RNA binding protein CPEB. Second, the regulation involves homeostatic feedback and tends to keep the total number of contacts between two neurons at a fairly constant level both at rest and following facilitation. That raises the question of how facilitation and homeostasis can coexist. A possible answer is suggested by the findings that they both involve spontaneous transmission and postsynaptic Ca²⁺, which can have bidirectional effects similar to LTP and LTD in hippocampus. In addition, long-term facilitation can involve a change in the set point of homeostasis, which could be encoded by plasticity molecules such as CPEB and/or PKM. A computational model based on these ideas can qualitatively simulate the basic features of both facilitation and homeostasis of the number of contacts.

Synaptic plasticity is a change in strength of the synaptic connection (postsynaptic potential or PSP) between neurons and includes increases during facilitation and decreases during depression. Plasticity is thought to underlie circuit formation during development and learning and memory in adults, and correspondingly to be defective in neurodevelopmental disorders including autism, ADHD, and schizophrenia as well as learning and memory disorders including Alzheimer''s, age-related memory loss, and drug addiction (Hawkins 2013; Hawkins et al. 2017). Most studies of molecular mechanisms of synaptic plasticity have focused on either changes at individual synapses or gene regulation in the cell nucleus. However, studies of long-term facilitation at Aplysia sensory neuron–motor neuron (SN–MN) synapses in isolated cell culture (Glanzman et al. 1990), sensitization in the intact animal (Wainwright et al. 2004), and long-term potentiation in hippocampal neurons (Antonova et al. 2001, 2009) have shown that there are also changes in the number of contacts between presynaptic varicosities and the postsynaptic neuron. We refer to these as synaptic contacts although not all of them are functional synapses (Kim et al. 2003). The number of contacts is thought to be an important determinant of the strength of the PSP (Zhang et al. 2003) and to be different for different neuron pairs. It also increases during long-term facilitation of the PSP and is thought to be a major determinant of the time course of the facilitation (Bailey and Chen 1989).As in other systems (Antonova et al. 2001, 2009; Holtmaat and Svoboda 2009), the contacts are dynamic and are continually being formed and eliminated, but the total number and the PSP remain fairly constant both at rest and during long-term facilitation (Miniaci et al. 2008; Chen et al. 2014). Furthermore, the number of contacts and the PSP return to baseline when maintenance of the facilitation is blocked, but the individual contacts are not all the same as they were before facilitation. These results have led some to suggest that memories are not stored at individual synaptic contacts, as is often supposed, but rather are stored in the nucleus (Chen et al. 2014). However, most of the previous experiments have involved a single SN and a single MN, so it has not been possible to examine the synapse specificity of the effects. Experiments with one SN and two MNs (Martin et al. 1997) or two SNs and 1 MN (Schacher et al. 1997) have shown that facilitation of the number of synaptic contacts and the PSP is specific to the stimulated synaptic pair (e.g., SN–MN1) and does not occur for the other pair (e.g., SN–MN2). These results should generalize to multiple pre- and postsynaptic partners and suggest two novel features of synaptic regulation during plasticity: (1) that the number of synaptic contacts between two neurons is regulated, and (2) that the regulation is homeostatic. We first describe those features and some of the evidence supporting them, then propose a model that could account for them and present computational modeling to illustrate the plausibility of the model.     

What worries first-year students? Psychometric properties of the Student Worry Scale

The transition to university can be stressful for first-year university students. Despite the fact where the feeling of worry is a shared symptom by various mental health issues, there is a lack of studies that investigate into this matter. As worry is a domain-specific construct, there is a need for a valid and reliable measure of worry specifically for university students. Hence, this study aimed to evaluate the psychometric properties of the Student Worry Scale (SWS), particularly in terms of its validity and reliability. For this purpose, the current study recruited a sample of 295 first-year students to evaluate the psychometric properties of SWS. Exploratory factor analysis yielded a five-factor structure of SWS, which explained 55.7% of the total variance. The yielded five factors were general worries, financial-related concerns, significant other’s well-being, academic concerns, and social adequacy concerns. Inter-correlations between the five factors were all significant (r ranged between 0.395 and 0.625). The SWS demonstrated good internal consistency in this study (Cronbach’s alpha ranged between 0.786 and 0.941). Overall, the SWS is psychometrically evidenced to be a reliable and valid content-based worry measure specifically for university students.     

笛卡尔的直观理论新探

直观概念在笛卡尔的认识论中具有重要的地位,直观是人类"良知"的最基本的体现,是整个科学认识活动的基础,直观的明见性和确定性也正是科学知识最全面的标准。笛卡尔的直观知识以及在此基础上构建起来的别的科学知识,在一定的程度上仅仅是认识当中的关于事物的知识,都是人类的理智观照之下的东西,而不是事物本身的真实状况。在直观的基础上形成的知识是绝对的知识,在这个意义上,直观的知识"我思我在"并不是偶然的,并不仅仅具有一种莱布尼兹所称的"感觉的直接性"。

Suicide Risk across Latent Class Subgroups: A Test of the Generalizability of the Interpersonal Psychological Theory of Suicide

It remains unclear whether the Interpersonal Psychological Theory of Suicide (IPTS; Joiner, 2005 ) is generalizable to the population or holds more explanatory power for certain subgroups compared to others. The aim of this study was to (1) identify subgroups of individuals who endorsed suicide ideation in the past month based on a range of mental health and demographic variables, (2) compare levels of the IPTS constructs within these subgroups, and (3) test the IPTS predictions for suicide ideation and suicide attempt for each group. Latent class, negative binomial, linear, and logistic regression analyses were conducted on population‐based data obtained from 1,321 adults recruited from Facebook. Among participants reporting suicide ideation, four distinct patterns of risk factors emerged based on age and severity of mental health symptoms. Groups with highly elevated mental health symptoms reported the highest levels of thwarted belongingness and perceived burdensomeness. Tests of the IPTS interactions provided partial support for the theory, primarily in young adults with elevated mental health symptoms. Lack of support found for the IPTS predictions across the subgroups and full sample in this study raise some questions around the broad applicability of the theory.
