自闭症谱系障碍(autism spectrum disorders,ASD)是一种复杂的神经发育疾病,其典型特征是社交障碍、限制和重复的行为和兴趣.此外,ASD个体往往表现出感知功能的非典型性(如感觉超敏感或低敏感).先前的知觉理论只能部分解释ASD个体与典... 自闭症谱系障碍(autism spectrum disorders,ASD)是一种复杂的神经发育疾病,其典型特征是社交障碍、限制和重复的行为和兴趣.此外,ASD个体往往表现出感知功能的非典型性(如感觉超敏感或低敏感).先前的知觉理论只能部分解释ASD个体与典型发育个体(typically developing,TD)之间的差异.Pellicano和Burr提出了贝叶斯预测模型,通过贝叶斯计算建模和预测编码理论将感知过程概念化,从新的角度去理解这种差异.该模型描述了感觉自下而上和认知自上而下的过程如何共同作用,并以不同的方式塑造了ASD的感知.本文对贝叶斯模型进行了全面的回顾,其中最突出的两个理论是“弱先验假设”和“ASD预测误差高且不灵活精度的假设”(HIPPEA).我们从高级的社会认知功能上和不同的感觉通道角度上检验了这些理论.结果显示,目前支持贝叶斯预测理论的证据是混合的,有的研究支持ASD个体的先验不足或在不断变化的环境中调整这些预测的灵活性较差,也有的研究指出ASD个体能够学习预测,拥有完整的预测能力,贝叶斯先验的整合上没有差异,还有一些研究在行为与神经影像学发现不一致.尽管贝叶斯ASD理论很有前途,可以帮助我们更好地理解ASD患者的非典型感知觉,但它在实证方面还面临着挑战.基于此,我们提出了现有研究的局限和未来发展的建议.总之,贝叶斯预测模型自提出以来,已经得到了有效应用和不断的验证.然而,该理论仍然是一个不断发展的概念,未来还需要大量的研究来更新和改进. 展开更多

Community resilience has received growing attention in disaster risk management policies and practices,especially in China.However,few applicable instruments are available as a baseline for profiling and estimating a community’s resiliency in the face of disasters.The purpose of this study is to cross-culturally adapt and validate the original version of the 10-Item Conjoint Community Resiliency Assessment Measurement(CCRAM-10)in China.Our study further investigates if and to what extent community members translate their participation in disaster risk reduction(DRR)activities into perceived community resilience.A Chinese version of CCRAM-10 was generated and applied to 369 participants from a rural and an urban community in southwest China affected by the 2008 Wenchuan Earthquake.Internal consistency reliability and confirmatory factor analyses were performed to test the assessment instrument’s applicability.The Communities Advancing Resilience Toolkit Assessment Survey was used to establish the convergent validity for the Chinese version of CCRAM-10.Multiple linear regression models were used to explore the correlations between respondents’participation in activities and their perception of community resilience,while controlling for basic socio-demographic variables.Analysis results demonstrated good internal consistency reliability(Cronbach’s alpha=0.85)and satisfactory convergent validity for the Chinese version of the CCRAM-10.Construct validity was also confirmed(χ~2/df=2.161;CFI=0.977;GFI=0.971;NFI=0.958;RMSEA=0.056;SRMR=0.030).The regression analysis results indicated that respondents’participation in DRR activities was positively correlated with their perception of community resilience.This study contributes to the wider collection of disaster studies by providing a tested tool for assessing community resilience in the context of China.Community workers and practice researchers may be interested in applying CCRAM-10 to evaluate the effect of specific DRR programmatic activities for improving community resilience. 展开更多

A new dual-fluid model considering phase transition and velocity slip was proposed in this paper and the Cunningham correction was used in the droplet resistance calculation. This dual-fluid model was applied to the numerical simulations of wet steam flow in a 2D LAVAL nozzle and in the White cascade respectively. The results of two simulations demonstrate that the model is reliable. Meanwhile, the spontaneous condensing flow in White cascade was analyzed and it infers that the irreversible loss caused by condensation accounts for the largest share (about 8.78% of inlet total pressure) in total pressure loss while the loss caused by velocity slip takes the smallest share (nearly 0.42%), and another part of total pressure loss caused by pneumatic factors contributes a less share than condensation, i.e. almost 3.95% of inlet total pressure. 展开更多

Mental health interventions following disasters have been criticized as individualistic, incomplete, and culturally insensitive. This article showcases the effects of a culturally relevant and sustainable psychosocial capacitybuilding project at the epicenter of the 2008 Wenchuan Earthquake. Specifically, the project focuses on women, a group that has received limited attention in post-disaster recovery in China. This qualitative research study(N = 14)sheds light on the characteristics and processes of the implementation of a post-disaster psychosocial intervention project in rural China. In addition, by adopting the Success Case Method as an evaluation approach, this study elucidates its effects on the psychological and social changes of the disaster victims. The findings capture five aspects of psychosocial changes: enriched daily life, better mood,enhanced self-confidence, increased willingness to socialize, and the provision of mutual help. This study hopes to encourage more culturally relevant and empowering practices for women in building their psychosocial capacity after disasters. 展开更多
