近年众多研究表明,经皮迷走神经刺激(tVNS)作为一种新型、非侵入式的神经调控技术对个体的抑制控制功能具有积极的调节作用。已有研究发现, tVNS对抑制控制的调节作用可能是通过调控蓝斑核-去甲肾上腺素系统(LC-NE)的活动和神经递质GABA的浓度来实现的。然而,目前对tVNS调控抑制控制的神经机制仍存在诸多尚未明确的问题。未来研究在进一步优化tVNS的刺激参数后,可以从tVNS对抑制控制能力受损群体的调控作用及机制、如何实现和增强tVNS长期积极效应等方面进行深入探索。 相似文献

We have a new understanding on a unified fracture criterion based on two kinds of strain energy density. A definite expression which is a function of Poisson’s ratio to describe a crucial parameter in the unified fracture criterion is derived. The critical value of Poisson’s ratio between brittle and ductile materials can be derived as 2/7 which is verified by experimental data. Besides, the effect of Poisson’s ratio on the fracture loci in stress spaces is studied using unified fracture criterion. It is found that the decrease in Poisson’s ratio increases the asymmetry of fracture loci between tensile stress states and compressive stress states in principal stress spaces and between Lode parameters are 1 and ?1 in deviatoric-stress spaces. In addition, stress triaxiality has a great effect on the fracture behaviour with different Poisson’s ratios. 相似文献

Ecological view of human development calls for an investigation of multiple contexts surrounding children. In South Korea, traditional Confucianism and recent technological advancements serve as influential social and cultural contexts that affect parent–child relations and child development. High levels of parental control and strong emphasis on academic achievement have long been distinctive features of Korean parenting practices, which are attributable to Confucian values. Additionally, Korean children’s mobile phone dependency (MPD) has become a growing concern, as South Korea developed as an IT powerhouse. Combined, these contexts resulted in high parental control of children’s mobile phone use, so that such electronic devices would not hinder learning and achievement. Effects of high parental control on children’s MPD and their school life, however, have yet to be discovered. We hypothesized, that, unlike parents’ intentions, psychological control is more likely to increase MPD and disrupt school life. To examine this research model, we made use of the first and third wave data from Korea Children and Youth Panel Survey. Participants were 2378 children (52.2 % boys) of the same age of 10 in the first wave. After multiple imputation for missing values, hierarchical logistic regression followed to examine the mediational model. The results verified the hypothesized model, showing significant adverse influence of psychological control on MPD, self-regulated learning and school adjustment. MPD fully mediated the effect of psychological control on self-regulations, while partially mediating the effects on school adjustment. Implications for Korean parents with regard to supporting children’s psychological autonomy was discussed. 相似文献

African American youth, especially those who live in low-income communities, are at increased risk for experiencing higher juvenile justice involvement, poorer mental health, low school engagement, higher illicit drug use, and STIs, relative to their higher income peers and those from other ethnic backgrounds. However, few studies have examined the relationship between family stressors and these multiple youth concerns. This study examines the relationship between family stress (i.e., having an adult in the home with a history of mental illness, substance use, and incarceration) and youth concerns such as substance use, mental health challenges, low school engagement, juvenile justice involvement, and STI risk behaviors. A total of 638 African American adolescents living in predominantly low-income, urban communities participated in the study by completing self-report measures on the above constructs. Logistic regressions controlling for age, gender, socioeconomic status, and sexual orientation indicated that adolescents who reported higher rates of family stress were significantly more likely to report mental health problems, delinquent behaviors, juvenile justice involvement, drug use, risky sex, and lower school engagement factors. Findings suggest that attending to the developmental concerns of youth also requires addressing the needs of the family unit. 相似文献

在含糊性问题研究领域,多值语义解释和超赋值语义解释是两个经典的研究进路。相较多值语义中的经典三值解释和基于概率赋值的模糊逻辑解释,范启德(1975)给出的超赋值语义由于引入了基于可能世界语义的可精确化结构,具有更强的表达力,能够弥补三值和模糊逻辑处理的很多不足。距离超赋值语义发表40余年后,秋叶研(2017)给出了同样满足可精确化结构条件的一个布尔多值解释。由于超赋值语义一直被当作典型的内涵语义处理方式,而在含糊性问题研究领域,布尔多值方法却在大多数时候被认为是模糊逻辑这个基于概率处理的典型的外延语义的复杂版本,内涵语义与外延语义的殊途同归,非常值得仔细思考和探究。本文将结合含糊性问题研究领域的多值语义解释和超赋值语义解释的演进过程,以内涵语义和外延语义的区分为切入点,最终指出,(当下主流定义下的)内涵语义与外延语义的界限是模糊的,而在原有界定基础上,对内涵语义增加“内涵语义要可以表达非线序的偏序结构”这一限制,能够进一步对内涵语义和外延语义进行区分。 相似文献
