On the estimation of non linear functions in stochastic volatility models

Abstract

This paper focuses on the inference of suitable generally non linear functions in stochastic volatility models. In this context, in order to estimate the variance of the proposed estimators, a moving block bootstrap (MBB) approach is suggested and discussed. Under mild assumptions, we show that the MBB procedure is weakly consistent. Moreover, a methodology to choose the optimal length block in the MBB is proposed. Some examples and simulations on the model are also made to show the performance of the proposed procedure.     

制度风险的法律维度: 突破非物质文化遗产保护的瓶颈

以风险理论审视非物质文化遗产的现行法律制度,根据风险产生根源不同,非物质文化遗产保护的制度风险会表现为制度运转失灵风险、制度功能偏差风险和公平性缺失风险。化解制度风险,形成制度风险的维度,不可基于同一个标准,而是需要在大的框架之下论及制度风险的法律管控,需要有针对性地创构"建立私权,善用公权"的多元法律控制体系,并在体系内引入技术规制,创设"非物质文化遗产权",推动民间习惯法与法律制度、公法与私法的互动式发展。     

“四史”教育融入高校思政课教学的五维逻辑进路

历史照亮过去，历史启迪未来。以党史、新中国史、改革开放史、社会主义发展史为核心内容的“四史”教育，是以历史为基础的思想政治教育。从党史、新中国史、改革开放史、社会主义发展史中挖掘思想政治理论课教育资源，对高校传承红色基因、落实立德树人根本任务具有重要的指导意义。以庆祝中国共产党成立100周年为契机，将“四史”教育融入高校思想政治理论课教学，必须遵循相应的逻辑理路：树立正确党史观、坚定理想信念的价值追求是融入的逻辑立场；强化大历史观、理解党的伟大贡献是融入的逻辑方法；坚持内在统一性、把握“四史”教育的整体性逻辑是融入的基本前提；抓住侧重点、精准对接各门大学生思想政治理论课程是融入的逻辑核心；坚持实践逻辑、引导大学生从“四史”中汲取智慧和力量是融入的根本遵循。     

“动物与人”：叙事伦理、悖反性与双重困境指向——论“抉择之痛”作为功能指涉的效力边际

对初始情境中受难者“陷困”功能的探讨，是“动物叙事”叙事语法研究中不容忽视的一环，其中贯穿了一个最为基础的叙事功能指向——“抉择之痛”。强调“动物与人”两类受难者角色在身体、心理抑或情感维度陷入某种矛盾与纠结的状态，并且彼此间时常呈现出一定的矛盾悖反性。这一角色身份由动物形象与人类形象分别或共同承担，均指向一种叙事伦理层面的现代境遇的表达。在题材范畴方面，这一功能指涉涵盖了家养类与野生类“动物叙事”各自的叙事范畴。其效力边际已不仅仅局限在单纯生态视域与人性指涉的层面，而是凸显现代语境下人类所面临的共通性的伦理困境：一种挥之不去的矛盾、困惑与不安的情感和心境的写照。     

Reducing attitudes of prejudice and discrimination through literature: a quasi-experiment on the upper key-stage 2 students of the British schools in Karachi,Pakistan

This study aims to explore the efficacy of literature relating to Anne Frank to reduce children’s attitudes of prejudice and discrimination with respect to specific dimensions, including ethnicity and race, religion and gender. A quasi-experiment was employed with pre-post control design. The sample consisted of 100 students of the upper key-stage 2 (UKS2) level, recruited from the two British schools in Karachi. These schools represented an Experimental Group (EG) and a matched Comparison Group (CG). A research instrument titled ‘Muggles world of differences’ (MWD) was developed and validated. It was administered on CG and EG, both before and after intervention. The intervention plan ‘Reading of Young Anne’s Literature’ (ROYAL) was developed based on selected readings from Anne Frank related literature (AFL). Intervention was provided to EG, while CG studied similar concepts using a more standard method. Results of the pretest revealed a high level of prejudice and discrimination in both the EG and CG, with no significant difference (p > 0.05) in the overall scores, as well as in the specific content domains. However, the post-test of the two groups revealed that the students in the EG had outperformed their CG counterparts in overall MWD scores, as well as in specific content domains. The difference was found to be significant (p < 0.05) with the large effect size (r = ?0.63). Results support the efficacy of teaching Anne Frank related literature in reducing attitudes of prejudice and discrimination.     

Developing a Rubric for Supervision of Students Counseling LGBTQ Clients

More than 100 pieces of anti-lesbian, gay, bisexual, transgender (LGBT) legislation are active in 2018. In this current political climate of “conscience clause” legislation, counselor educators and supervisors are poised to adopt more holistic practices in assessing and evaluating student and supervisee readiness to work with LGBT queer (Q) clients. The purpose of this article is to present a dispositional framework for assessment and evaluation and introduce the flexibility, integrity, awareness, stability, compassion, and openness (FIASCO) rubric of professional counseling dispositions. Two court cases, Keeton v. Anderson-Wiley and Ward v. Wilbanks, are used as case examples for applying the FIASCO rubric to situations involving LGBTQ clients.     

陈训慈与抗战时期浙江省图书文化事业

抗战时期，中国图书文化事业备受日寇摧残，众多文化典籍被日寇劫掠而去或毁于战火。在此特殊时期，陈训慈征求各类文献，举办图书文献展览会，保护文澜阁《四库全书》与天一阁藏书，撰文与创刊宣传浙江图书文化事业，创建图书馆协会推进全省图书文化事业，为图书文化事业做出了难以磨灭的贡献。     

走自己的路:建党百年中国道路自信的生成逻辑及提升路径

自信是一种信念及精神,中国道路自信是中华儿女对中华民族发展能力及前途的信任,其形成与中国百年发展辉煌成就息息相关.中国道路自信源自中国道路的正确选择.建党百年来,中国共产党带领中华儿女历经千难万险,先后成功开辟新民主主义革命道路、社会主义改造及社会主义建设道路、中国特色社会主义道路.全国人民在百年磨砺中增强了中国道路自信.这种自信承载着中华儿女的无数梦想,是中华民族复兴的软实力.树立中国道路自信的理论前提,关键在于对中国道路优越性的彰显.只有将其置于不同参照系中进行多维度比较,才能使其优越性得以全面彰显,并愈加坚定不移地沿着这条道路阔步前行.显然,站在新时代历史方位上,通过梳理、总结建党百年来中国道路发展历程,将中国道路置于自身与"他者"之历史与现实中,进行共时态与历时态之比较,以唯物史观回望并厘清建党百年来中国道路自信生成逻辑,具有极其重大意义,既能彰显中国特色社会主义道路的优越性,又能激发全体中华儿女愈加自信地"走自己的路"——中国特色社会主义道路,筑牢中华民族共同体意识,阔步迈向全面建设社会主义现代化国家新征程.     

高校开展咏唱爱国主义歌曲活动的意义和经验分析——以祖国七十大庆高校开展咏唱爱国主义歌曲活动为例

爱国主义歌曲作为对祖国抒发赞颂之情的歌曲,是“光荣颂”“欢乐颂”“祝福颂”的有机统一,是培育和践行社会主义核心价值观的重要载体。从精神价值而言,爱国主义歌曲具有社会公共性、历史恒久性、无比崇高性。高校开展咏唱爱国主义歌曲活动,能增进学生对祖国的自豪之情,提升其民族自信,激发其报国之志。高校开展咏唱爱国主义歌曲活动,即要精选优异的爱国主义歌曲音乐本体,又要注重发挥高校教师的带头作用,还要加强学校各级组织机构和辅导员队伍的引领作用。高校党政领导对这类歌咏活动要进一步提高认识站位、增强重视程度、加强条件支持。     

宋代閤职的内外演变与磨勘叙迁探析

宋代共设有三等閤职，最初供职于閤门，后閤职官员出外任职情况变得普遍，直接推动了外任武官兼带閤职制度的发展，此后閤职作为武官兼带的一种职名，成为奖励军功以及控制武官的一种有效手段。而閤职制度的发展也使閤职作为武臣清选的地位逐渐确立，表现之一就是在磨勘叙迁上较一般武官而言具有一定的优越性。同时，内外不同的閤职在磨勘制度上也有一定的差异，这些差异的产生也加深了閤职作为武臣清选的内涵。
