Local asymptotic properties for Cox-Ingersoll-Ross process with discrete observations

In this paper, we consider a one-dimensional Cox-Ingersoll-Ross (CIR) process whose drift coefficient depends on unknown parameters. Considering the process discretely observed at high frequency, we prove the local asymptotic normality property in the subcritical case, the local asymptotic quadraticity in the critical case, and the local asymptotic mixed normality property in the supercritical case. To obtain these results, we use the Malliavin calculus techniques developed recently for CIR process together with the estimation for positive and negative polynomial moments of the CIR process. In this study, we require the same conditions of high frequency and infinite horizon as in the case of ergodic diffusions with globally Lipschitz coefficients studied earlier in the literature. However, in the non-ergodic cases, additional assumptions on the decreasing rate are required due to the fact that the square root diffusion coefficient of the CIR process is not regular enough.     

关于劳动合同法的几个基本问题

劳动合同法自制定、颁布到实施就一直存在各种不同主张。由于人们对劳动合同法基本问题缺乏共识,对诸如劳动合同法与市场经济、劳动合同法的属性、劳动的弹性化、劳动合同法与现实的关系、劳动纠纷的调解与仲裁、劳动合同法与常识、劳动合同的解除、劳动合同法与国家责任、劳动合同法的发展完善等问题还需要加强研究,以有助于劳动合同法的健全完善和有效实施。     

‘Clock-watching and box-ticking’: British local authority planners,professionalism and performance targets

The speed of the statutory planning system has concerned UK Governments for decades. The Labour Government of 1997–2010 placed particular emphasis on increasing the efficiency of public services through performance targets. Whilst the subsequent Coalition Government of 2010–2015 removed many targets, those measuring the speed of planning application processing were kept. These performance targets have important potential implications in terms of the autonomy and space for discretionary judgement traditionally seen as intrinsic to the professional nature of planning. Empirical material exploring how British local authority planners responded to these targets suggests they have both restricted and empowered professionals and, whilst changes to practice have occurred, professional identities have remained more resilient. This contradictory picture highlights the importance of considering the role of frontline professionals in implementing reforms.     

环境污染对居民的政府信任和政治参与行为的影响

环境污染对居民健康的负面影响已被诸多研究所证实,然而环境污染侵害的远不止公众健康。利用2010年中国综合社会调查数据,系统考察居民感知的居住地环境污染状况对居民的政府信任度和政治参与行为的影响。主要研究结果显示:居民感知的居住地环境污染严重程度损害居民对政府的信任度,但不会抑制居民的政治参与行为。居民感知的居住地不同环境污染状况对中央和地方政府信任度的影响存在差异,居民感知的空气污染严重程度对中央政府信任的影响比对地方政府信任的影响更大,而居民感知的水污染严重程度对地方政府信任的影响比对中央政府信任的影响更大,这主要源于居民对中央和地方政府不同环境治理责任的不同判定。环境污染状况对不同区域和居住地居民的政府信任度的影响存在差异,空气污染损害居民对中央政府的信任主要表现在东部地区、城市地区,而水污染损害居民对地方政府的信任在东、中、西部地区,城市和农村地区均有表现。居民主观幸福感的提升有助于增强其对中央和地方政府的信任,而互联网使用强度的增大降低居民对中央政府的信任,也会抑制居民的政治参与行为。因此,环境污染治理关系到居民对政府的信任和社会稳定,各级政府应下大力气进行环境污染治理,建立公正透明的环境信息披露制度,并强化对民众感受的调查研究,以增强居民对政府的信任和政治参与。     

Homework: Routine,social aesthetics and the ambiguity of everyday life

Routine is a central feature of everyday life, yet its peculiar rhythms, and the range of experiences associated with it, are often neglected within cultural studies and sociology. Simmel’s attempt to provide a sociological aesthetics is seen as a project that needs reanimating for the study of everyday life routines. This does not mean, however, that Simmel is the only, or the best, guide to the aesthetic dimensions of everyday routine life. In an attempt to provide some co-ordinates for instigating a socio-aesthetic approach to routine, this paper discusses a number of writers who couple aesthetics and the everyday, and who might provide frameworks for the study of experiential aspects of routine life. It also suggests that an inverted reading of John Dewey could provide socio-aesthetic study with the ‘formless’ forms required to bring everyday background routines into the foreground. The socio-aesthetic study of cooking undertaken by Luce Giard provides an example of the complexity of such an approach. Lastly the article looks briefly at new directions for ‘everyday life aesthetics’, more specifically at Henri Lefebvre’s unfinished project of rhythmanalysis.     

哥尔多尼的即兴喜剧改革

18世纪中期,哥尔多尼对旧式的即兴喜剧在剧本、舞美、人物等多个方面进行了逐步的改革,尽管在这些改革中传统即兴喜剧的一些重要要素被减弱或者消除,但这些改革使即兴喜剧这一传统剧种与当时的时代精神更为契合.哥尔多尼对即兴喜剧的改革不仅仅使这一在当时已稍显颓势的传统剧种重新焕发了生机,他在这一系列改革中的创作经验和成果也奠定了之后意大利现实主义喜剧的基调.
