Advances in computational linguistics and discourse processing have made it possible to automate many language- and text-processing mechanisms. We have developed a computer tool called Coh-Metrix, which analyzes texts on over 200 measures of cohesion, language, and readability. Its modules use lexicons, part-of-speech classifiers, syntactic parsers, templates, corpora, latent semantic analysis, and other components that are widely used in computational linguistics. After the user enters an English text, CohMetrix returns measures requested by the user. In addition, a facility allows the user to store the results of these analyses in data files (such as Text, Excel, and SPSS). Standard text readability formulas scale texts on difficulty by relying on word length and sentence length, whereas Coh-Metrix is sensitive to cohesion relations, world knowledge, and language and discourse characteristics.  相似文献

老子与道教     
老子认为,为学是求知识,为道是求智慧.真正的智慧是超理性、超逻辑的一种体验方式,只有通过为道的方法才能悟道.老子的道,与基督教的上帝是极其接近的概念.道是非人格化、非神的上帝,而上帝是人格化的、神圣化的道.道最初是一个哲学概念,表示规律、法则,但它潜在着一种被神化的内涵.一旦社会有了需要,它可以转变为一种宗教的核心理念.例如在道教中,老子为道的方法发展成为道教修行的方法,老子的<道德经>演绎成道教各类经书.  相似文献

Researchers have documented that vacant lot greening can reduce community-level crime and violence. Busy Streets Theory (BST) suggests that residents who are involved in the greening process can help to improve physical environments and build social connections that deter crime and violence. Yet few researchers have explored how community engagement in the greening process may affect crime and violence outcomes. We applied BST to test the effects of community-engaged vacant lot greening compared to vacant lots that received either professional mowing or no treatment, on the density of violent crime around study lots. Using mixed effects regression models, we analyzed trends in violent crime density over the summer months from 2016 to 2018 at 2102 street segments in Youngstown, OH. These street segments fell within 150 meters of an intervention parcel that was classified as one of three conditions: community-engaged maintenance, professional mowing, or no treatment (control). We found that street segments in areas receiving community-engaged maintenance or professional mowing experienced greater declines in violent crime density than street segments in areas receiving no treatment, and more decline occurred in the community-engaged condition compared to the professional mow condition. Our findings support BST and suggest that community-engaged greening of vacant lots in postindustrial cities with a concentrated vacancy can reduce crime and violence.  相似文献

Can subsidies promote Pareto‐optimum coordination? We found that partially subsidizing the cooperative actions for two out of six players in a laboratory coordination game usually produced better coordination and higher total social welfare with both deterministic and stochastic payoffs. Not only were the subsidized players more likely to cooperate (choose the Pareto‐optimum action), but the unsubsidized players increased their expectations on how likely others would cooperate, and they cooperated more frequently themselves. After removal of the subsidy, high levels of coordination continued in most groups with stochastic payoffs but declined in deterministic ones. This carry‐over disparity between the deterministic and stochastic settings was consistent with the economic theories that agents were more likely to keep the status quo option under uncertainty than without uncertainty. Hence, players with stochastic payoffs were more likely to keep the high coordination level (status quo) brought by the subsidy in the previous subsidy session. A post‐game survey also indicated that with stochastic payoffs, players focused on risk reduction. Temporary subsidies promoted lasting coordination because even after subsidy was removed, players still assumed that others players would prefer reduced risks from cooperation. With deterministic payoffs, however, the subsidy might crowd out other rationales for coordination, with many players indicating that the subsidy was the only reason for anyone to cooperate. Hence, the coordination level dropped when the subsidy was removed. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

Depressive symptoms and empty nest phenomenon of rural elderly people are both important public health issues, which should not be ignored. We aimed to estimate the prevalence of depressive symptoms and related factors of the empty nest elderly in rural China. We recruited 3182 eligible subjects and gathered data by face-to-face interview. Multivariate logistic regression models were used to explore the related factors of depressive symptoms. The present study showed that the prevalence of depressive symptoms significantly differed between empty nest old adults and non-empty nesters (24.1% vs. 19.0%). The elderly living alone had highest OR of depressive symptoms. Depressive symptoms of empty nest elderly was associated with sleep quality, economic status, pain, social support and ADL. While it was associated with gender, economic status, pain and PSMS in non-empty nest group. Number of chronic disease showed significant associations with depressive symptoms in the elderly living alone. Subjective support, support utilization and pain were positively associated with depressive symptoms in the elderly living with spouse. Sleep quality, economic status and ADL were common factors. Depressive symptoms obviously prevail among empty nest elderly than non-empty nesters. It reminded us that complementary social support from family and society is essential.  相似文献

Extensive evidence has been obtained that supports an association between an attentional bias (AB) toward negative stimuli and vulnerability to stress-related psychopathology, little is known regarding the characteristics of individual AB in different posttraumatic growth (PTG) levels. The current study used a modified dot-probe task to investigate if individual differences in AB towards either positive or negative emotional stimuli, are related to self-reported PTG. A sample of 202 patients completed the experiment. Patients with low levels of PTG did not exhibit AB toward negative or positive stimuli, patients with medium levels of PTG had difficulty disengaging attention from negative stimuli, patients with high levels of PTG had difficulty disengaging attention from positive stimuli. And the AB towards positive stimuli was only predictive for PTG. An implication of this finding is that there are different characteristics of implicit cognitive processing in patients with different levels of PTG, suggesting the necessity of psychological intervention on the accidentally injured patients.  相似文献

儒家以怨的发生、危害和化解为理论框架,构建了个体和社会怨情的理论体系。道德人格的缺失是个体怨情产生的根本原因,耽溺于利、为善以求福报和不忘旧恶是个体怨情产生的直接原因。个体怨情压抑于心,危害着心理健康,扭曲着道德人格。儒家通过涵养道德人格化解个体怨情的路径可以概括为:求仁而得仁则无怨; 忠恕则无怨; 安于礼乐则无怨; 诗可以怨; 以直报怨。社会怨情的产生主要源于苛政、不公和重刑轻教。社会怨情是社会动乱的根源。儒家化解社会怨情的路径可以概括为:闻怨而敬德迁善则民无怨; 政均则民无怨; 仁政则民无怨。  相似文献
