A novel characteristic value correction iteration method

It has greater randomness that the existing characteristic value correction iteration method terminates the iterative progress by artificially setting threshold to acquire the better intermediate estimates than least squares. To address this problem, the novel characteristic value correction iteration method is proposed in this article. Considering the balance between solutions and residuals, L curve drawn to express the correlation of solutions and residuals and the iteration time correspond to the maximum curvature point is chosen as the iteration termination condition to obtain the “optimal” intermediate estimates. Numerical experiment is carried out to demonstrate the correctness of the theoretical analysis.     

Setting aside mood-biased thoughts and judgements: theory-based bias correction / Apartar las opiniones y los pensamientos sesgados por el estado de ánimo: la corrección del sesgo basada en teoría

Abstract

When people perceive their thoughts and judgements as unduly affected by some biasing factor (in themselves or in the judgement setting), they often attempt to avoid or remove those biases. Theories describe different psychological mechanisms guiding these efforts. We review the primary theories of bias correction and focus on the use of naive theories of bias in attempts to form accurate assessments of judgement targets. One distinguishing feature of the theory-based correction approach is its ability to deal with corrections for contrastive biases (i.e., biases that lead judgements in a direction opposite to the meaning of the biasing factor). Another is that any perceived biasing factor can result in corrections, even when those factors are not easily mapped into the kinds of mental representation mechanisms that form the heart of alternative approaches. We use corrections for mood-based biases to illustrate the utility of the theory-based correction approach, even though many mood-based biases can be conceptualized in ways that fit alternative approaches to bias correction. Implications for correction of many potential types of biases are discussed.     

The use of Facebook for information seeking,decision support,and self-organization following a significant disaster

The wide-spread proliferation of the Internet has revolutionized the ways that individuals obtain, interpret, and respond to information in the aftermath of disaster. An F3 tornado that impacted the community of Goderich, Ontario, on 21 August 2011 provided the opportunity to examine how people utilized Facebook and Facebook groups to seek out information, self-organize, and provide support. This mixed-methods project was conducted in two phases. First, semi-structured interviews (n?=?35) were conducted with Goderich area residents on their experiences using social media after the tornado. Next, all of the publicly available posts and replies on the Goderich Ontario Tornado Victims and Support (GOTVS) Facebook group were gathered and analysed using computer-assisted content analysis. The results demonstrate that Facebook was a highly influential source of information and support, particularly in the immediate aftermath of the disaster. Although misinformation and gossip occurred, the tendency was for the group to self-moderate inaccurate information. Public engagement by local officials may further reduce misinformation and encourage public confidence. The results also show that GOTVS activity significantly declined after two weeks. This abrupt decrease in public attention suggests that the window for engagement by public officials is narrow. As such, officials should have a social media plan in place so that they may engage with the public during the critical response phase when their participation may yield the greatest benefit. Finally, this research underscores the potential for analysing Facebook content using computer-assisted content analysis, a method that may be of interest across the social sciences.     

Asymptotic expansions of the distributions of the chi-square statistic based on the asymptotically distribution-free theory in covariance structures

An asymptotic expansion of the null distribution of the chi-square statistic based on the asymptotically distribution-free theory for general covariance structures is derived under non-normality. The added higher-order term in the approximate density is given by a weighted sum of those of the chi-square distributed variables with different degrees of freedom. A formula for the corresponding Bartlett correction is also shown without using the above asymptotic expansion. Under a fixed alternative hypothesis, the Edgeworth expansion of the distribution of the standardized chi-square statistic is given up to order O(1/n). From the intermediate results of the asymptotic expansions for the chi-square statistics, asymptotic expansions of the joint distributions of the parameter estimators both under the null and fixed alternative hypotheses are derived up to order O(1/n).     

纠偏与制衡:1940年代中国现代诗学的自觉追求

1940年代是中国现代诗学成熟的年代,其主要标志是各种诗学呈现出文化融合的趋势,即朝着一切可能融合的方向发展.独创性寓于变化之中,每一种独特的个性都可以创造出一种独特的融合来.这一时期的现实主义、浪漫主义和现代主义就不像以往那样泾渭分明,老死不相往来.正因为如此,才有这种借"他山之石,可以攻玉"的可能.也就是说,有了自己与其他诗学的参照,才能更明晰自己的不足和缺陷."纠偏"与"制衡"便成为这一时期现代诗学的共同主题.纠偏实际上是对本诗歌思潮内部出现的问题进行纠正.制衡主要是针对其他诗歌思潮的弊端进行反拨和约束,它往往是以论争的形式出现.实践证明:只有通过对内对外的纠偏与制衡,才能促进诗歌文化的融合与繁荣.

钱实甫《清代职官年表》具有较高的史料价值,然其中所载山东布政使、按察使两司官员的族籍有漏误,根据《清代官员履历档案全编》及各地方史志等基本史料对其误漏处进行勘补,当有裨于相关地方史研究的深入进行。     

通货膨胀率和股票收益率的相关性的实证研究——基于马尔可夫转换模型

通过建立马尔可夫向量误差修正模型，分别在高通胀和低通胀两个区制内研究股票实际收益率和通货膨胀率的相关性。根据实证分析结果，股指和CPI之间存在正向协整关系，协整误差对CPI 的短期波动具有正向的修正作用。对于同步相关性，在低通胀区制内，股票收益率和通货膨胀率正相关，在高通胀区制内，股票收益率和通货膨胀率负相关。短期相关性不显著。     

帮助信息网络犯罪活动罪的规范属性与解释纠偏

信息技术的发展推动网络犯罪参与结构由传统犯罪层级式的金字塔结构向扁平式的链条结构转变,使得立法增设帮助信息网络犯罪活动罪以应对犯罪参与模式的改变,解决网络犯罪行为不适应传统共同犯罪理论的难题。立法者增设帮助信息网络犯罪活动罪以规制“不契合共犯理论的帮助行为”,但未就帮助信息网络犯罪活动罪的性质加以说明。理论界关于该罪性质的探讨主要着眼于共犯性的视角,但是以共犯性解释该罪的性质又会产生正犯不存在或者难以查证时归责标准阙如、意思联络趋弱而难以认定共犯、共犯与正犯危害性异化致使按照共犯理论归责违背罪刑均衡原则等适用困境。量刑规则说、共犯正犯化等以完全共犯性为着力点的学说,忽视了帮助信息网络犯罪活动罪的正犯属性,造成了适用困境并违背了对该罪的立法初衷。故此,跳出传统的对罪名性质解释单一的桎梏,承认部分帮助信息网络犯罪活动罪的正犯性,根据“契合共犯理论的帮助行为”与“不契合共犯理论的帮助行为”的不同,在“共犯性”与“正犯性”双重视角下区分认定该罪的性质,使得同一罪名在不同的适用情形下呈现动态的性质解读,以突破现有理论的适用困境。这对于契合司法实务向多元性与不可预测性发展,应对因传统刑法理论相对滞后而导致适用冲突不断的现实难题,对纠偏帮助信息网络犯罪活动罪的适用等,尤为必要。
