A note on stable limit theory for the OLSE with non usual rates and the heteroskedasticity robust Wald test

We are occupied with an example concerning the limit theory of the ordinary least squares estimator (OLSE) when the innovation process of the regression has the form of a martingale transform the iid part of which lies in the domain of attraction of an α-stable distribution, the scaling sequence has a potentially diverging truncated α-moment, and the regressor process has a potentially divergent truncated second moment. We obtain matrix rates that reflect the stability parameter as well as the slow variations present in the aforementioned sequences, and stable limits. We also derive asymptotic exactness, consistency, and local asymptotic unbiasedness under appropriate local alternatives for a heteroskedasticity robust Wald test based on subsampling. The results could be useful for inference on the factor loadings in an instance of the APT model.     

On the mean L1-error in the heteroscedastic deconvolution problem with compactly supported noises

We study the heteroscedastic deconvolution problem when random noises have compactly supported densities. In this context, the Fourier transforms of the densities can vanish on the real line. We propose a truncated type of estimator for target density and derive the convergence rate of the mean L¹-error uniformly over a class of target densities. A lower bound for the mean L¹-error is also established. Some simulations will be given to illustrate the performance of the proposed estimator.     

A unified approach to stochastic comparisons of multivariate mixture models

In this paper, we consider a unified approach to stochastic comparisons of random vectors corresponding to two general multivariate mixture models. These stochastic comparisons are made with respect to multivariate hazard rate, reversed hazard rate and likelihood ratio orders. As an application, results are presented for stochastic comparisons of generalized multivariate frailty models.     

A perfect storm: Challenges encountered by family caregivers of persons with Alzheimer’s disease during natural disasters

ABSTRACT

Since Hurricane Katrina there has been a movement across the U.S. to examine best practice for disaster response within the aging population. However, little is known about the experience of natural disasters from the perspective of family caregivers of persons with Alzheimer’s disease and related dementia (ADRD). In this exploratory, qualitative study, family caregivers (n=27) were interviewed about their experience with the historic 2015 South Carolina flood. By using thematic analysis, themes were identified to better understand what unique challenges caregivers of person with ADRD experienced. While many caregivers stated they had experienced a natural disaster previously, none had ever done so in their current caregiving role. The caregiving role affected their ability to prepare for the storm and influenced their decision-making regarding evacuation and utilization of recovery resources. Thus, caregivers were confronted by a “perfect storm” of circumstances and uncertainty. Family caregivers need to have actionable emergency plans for disasters that are specific to their role as caregivers of persons with ADRD. Study implications also suggest the role social work professionals can have in educating, advocating, evaluating, and coordinating support to assist caregivers of persons with ADRD as a potentially vulnerable and at-risk population during all phases of disaster.     

我国可再生能源法律法规与政策研究

近年来,我国出台了一系列可再生能源法律法规和相关政策,逐渐形成了以《可再生能源法》为主、相关配套法律法规为辅的较为完善的可再生能源法律法规和政策体系。但是,国家在不断完善可再生能源法律法规和相关政策的过程中,也存在着法律法规不齐全、综合性较差、内部条款不协调、立法级别低、与保护自然生态环境的联系不够紧密等问题,与发达国家和地区相比仍有一定的差距。针对这些问题,我国应通过落实现有的可再生能源法律及政策保障制度、完善可再生能源立法和政策体系、协调可再生能源法律法规与政策和其他相关法律与政策之间的关系、加大可再生能源开发利用监管力度、坚持和完善能源市场化发展机制和公民参与机制等措施,不断完善和改进我国的可再生能源法律法规和政策体系。     

全球经济社会转型与马克思社会哲学模式的再认识

建立在劳动和资本分析基础上的“经济基础-上层建筑”、“自然关系-社会关系”双层冲突论,构成马克思社会哲学的完整模式。“西方”与“非西方”世界构成当今全球经济社会转型紧密联系的两面。仅从西方世界内部来看,其消费社会转型使“消费”、“社会关系”等上升为其社会矛盾的主要方面,“生产”、“自然关系”等则相对退居其次,这导致其内部社会冲突的“去自然化”;而从全球范围来看,西方通过资本跨国流通把作为“人与自然之间的物质变换活动”的生产转移到非西方国家,则是将全球社会冲突“再自然化”的现实依据。“自然关系一社会关系”之间的冲突,构成当今全球经济社会转型中的主要矛盾之一,重构马克思社会哲学模式,具有极其重大的时代意义和本土意义。     

马克思主义科学哲学的两个研究传统——中俄科学哲学的发生学比较

俄(苏)和中国的科学哲学同属马克思主义传统,但各有特点.俄(苏)科学哲学的基础是苏联时期的自然科学哲学问题研究,20世纪60年代发生的"认识论转向"促成了俄(苏)科学哲学的兴起.中国科学哲学的产生根源于自然辩证法研究范式的转换.中俄科学哲学的比较研究,既可以揭示哲学的民族性,更可以从一个侧面反映各自民族的文化个性.     

基于广义双曲线分布的人民币汇率波动性研究

针对人民币汇率的波动性问题,运用广义双曲线分布,对2006年1月4日到2015年7月24日美元兑人民币汇率的波动特征进行实证分析。研究认为,人民币汇率不仅具有显著的“尖峰厚尾”特点,而且具有波动的非对称性和集群性特征,同时发现GH分布能较为准确地描述和呈现美元兑人民币汇率收益率波动状况的分布情况。     

未完成的“自然社会”:现代社会的人性基础与规范构成

对于《自然社会》关注的现代社会的规范性秩序问题,自然状态、自然法与建国契约是三个主要环节。对该书的批评也集中在这三个方面：自然状态与人性论,自然状态的道德性质,以及政治社会与规范秩序的奠基关系。自然状态学说通过自爱与社会性建立的自然社会性是理解现代社会道德关系的出发点。在考虑现代社会丰富和充实这一道德关系的努力之前,应当先理解人是如何成为一个孤独的陌生人的。从这一自爱的社会性出发,《自然社会》将霍布斯笔下的自然状态理解为道德空间乃至法权状态,但并不同意这一空间是具有内在道德尺度或客观道德科学基础的规范性秩序。作为现代国家规范性基础的道德尺度是与政治社会同步奠立的。
