碳市场建设对资源型城市资源依赖度的影响研究——基于异期DID模型

本文以降低资源依赖度作为切入点,以中国资源型城市为样本,鉴于不同碳交易试点地区开展试点工作的时间不一致,采用异期双重差分法（DID）考察碳交易市场试点对资源型城市资源依赖度的影响。实证结果发现：碳交易能够较为显著地降低资源型城市对传统资源的依赖程度,但此种影响具有一定滞后性,且平行趋势检验和安慰剂检验结果均能够支持这一实证结果。本研究结论对于增强中国碳交易市场发展信心、促进区域经济绿色低碳转型有一定的积极作用。     

Testing a model of emotional and coping responses to problems in adaptation: Foreign students at a Canadian university

The purpose of this research was to develop and test a model of cross-cultural adaptation which proposes that adaptation to movement across cultures involves three processes: learning new social norms, matching behavior to these norms, and matching one's self-concept to the newly acquired behaviors and social norms. According to this model, adaptation problems arise when the foreigner fails in one or more of these processes so as to create various types of mismatches between the components of norms, behavior, and self-concept. Each type of mismatch was hypothesized to lead to a particular affective response and to be most effectively resolved by unique coping strategies which would restore balance among these three components. Successful adaptation, then, occurs when the foreigner uses the coping strategy which is appropriate to the type of mismatch problem encountered in the acculturation situation.This study tested the hypothesized relationship between mismatch problem, affective response, and coping strategy. Subjects were 40 foreign and 40 Canadian students at a Canadian university. They were presented with scenarios depicting five types of mismatches in hypothetical acculturation situations. Results showed that subjects' interpretations of these agreed with the mismatches proposed by the model. Moreover, their reported affective and coping responses confirmed the majority of the hypothesized relationships. These findings suggest the mismatch model may serve as a good framework for classifying diverse adaptation problems and for predicting the coping strategies which would effectively resolve these.

Population differences in constructive memory

An experiment was conducted to evaluate constructive memory in fourth-grade low-SES black and middle-SES white children. The children were read nine short passages; each passage was composed of two premise statements and a filler sentence. The children were tested by a recognition procedure. Thirty-six test sentences were presented randomly. Four sentences were associated with each passage (true premise, false premise, true inference, and false inference). Subjects were asked to make yes/no recognition decisions based on whether the test sentence was identical to a sentence presented at study. Middle-SES white children made few errors, except to true inference test sentences. This pattern of performance is consistent with the constructive view of memory. Low-SES black children also had a high error rate to true inference items. However, this outcome may not reflect constructive memory because they also had a high error rate to some of the other types of test sentences.     

辽太祖封长子倍为人皇王之意探析

辽太祖东征渤海后，从现实出发将精通汉唐文化，拥有文治武功的皇太子耶律倍改封人皇王，建立东丹国，因宜为势治理渤海的同时，以期消除大举南下辟地的分歧，实现思想统一，最终酬其中国之志。这种变化同时也取决于耶律倍的个人素质。     

The Integration of Common Core and Response to Intervention: Supporting Vulnerable Readers in a Time of Sophisticated Standards

The Common Core State Standards and Response to Intervention are significant contemporary educational initiatives that have emerged largely in isolation from one another. We argue that an integration of these initiatives is beneficial. We trace the independent development of these two initiatives and offer suggestions for how they might fruitfully transact, fully supporting vulnerable readers in their efforts to master sophisticated standards. Results from a school implementing these initiatives as an integrated whole are discussed.     

Assessing the Sensitivity of Weighted Least Squares Model Fit Indexes to Local Dependence in Item Response Theory Models

Given the relationships of item response theory (IRT) models to confirmatory factor analysis (CFA) models, IRT model misspecifications might be detectable through model fit indexes commonly used in categorical CFA. The purpose of this study is to investigate the sensitivity of weighted least squares with adjusted means and variance (WLSMV)-based root mean square error of approximation, comparative fit index, and Tucker–Lewis Index model fit indexes to IRT models that are misspecified due to local dependence (LD). It was found that WLSMV-based fit indexes have some functional relationships to parameter estimate bias in 2-parameter logistic models caused by violations of LD. Continued exploration into these functional relationships and development of LD-detection methods based on such relationships could hold much promise for providing IRT practitioners with global information on violations of local independence.

Dependency structure language model for topic detection and tracking

In this paper, we propose a new language model, namely, a dependency structure language model, for topic detection and tracking (TDT) to compensate for weakness of unigram and bigram language models. The dependency structure language model is based on the Chow expansion theory and the dependency parse tree generated by a linguistic parser. So, long-distance dependencies can be naturally captured by the dependency structure language model. We carried out extensive experiments to verify the proposed model on topic tracking and link detection in TDT. In both cases, the dependency structure language models perform better than strong baseline approaches.
