Threshold Estimation for Stochastic Processes with Small Noise

Consider a process satisfying a stochastic differential equation with unknown drift parameter, and suppose that discrete observations are given. It is known that a simple least squares estimator (LSE) can be consistent but numerically unstable in the sense of large standard deviations under finite samples when the noise process has jumps. We propose a filter to cut large shocks from data and construct the same LSE from data selected by the filter. The proposed estimator can be asymptotically equivalent to the usual LSE, whose asymptotic distribution strongly depends on the noise process. However, in numerical study, it looked asymptotically normal in an example where filter was chosen suitably, and the noise was a Lévy process. We will try to justify this phenomenon mathematically, under certain restricted assumptions.     

The Othering of Muslims: Discourses of Radicalization in the New York Times, 1969–2014

In this article, I engage with Edward Said's Orientalism and various perspectives within the othering paradigm to analyze the emergence and transformation of radicalization discourses in the news media. Employing discourse analysis of 607 New York Times articles from 1969 to 2014, this article demonstrates that radicalization discourses are not new but are the result of complex sociolinguistic and historical developments that cannot be reduced to dominant contemporary understandings of the concept or to singular events or crises. The news articles were then compared to 850 government documents, speeches, and other official communications. The analysis of the data indicates that media conceptualizations of radicalization, which once denoted political and economic differences, have now shifted to overwhelmingly focus on Islam. As such, radicalization discourse now evokes the construct radicalization as symbolic marker of conflict between the West and the East. I also advanced the established notion that the news media employ strategic discursive strategies that contribute to conceptual distinctions that are used to construct Muslims as an “alien other” to the West.     

他知与自知:多元无知理论视角下的老年人媒介形象

老龄化进程的持续加快将老年群体置于国家、社会和媒体重点关注中,老年人的媒介形象影响着社会公众对老年人的态度和行为。本研究基于多元无知理论视角探讨老年群体的自我认知与他人认知,通过问卷调查发现:中青年群体和老年群体都对老年人形象呈积极正面的认知;但老年人高估了中青年人对老年人的负面态度,低估了中青年人对老年人的正面态度,老年人感知的态度与中青年人的实际态度存在程度上的认知差异;媒介说服推论和敌意媒介效果解释了这种认知偏差。研究结果有助于提高老年群体对他人认知的准确判断,更好地认识自我,通过自知建立自信与自尊。
