关于量子控制系统的哲学思考

环境对量子控制系统的消相干揭示了一个事实,即量子世界里的系统将是一种全新的系统,它是某种开放的、数学的、并且是基于量子逻辑的系统。笔者认为,假如仍然还是立足经典思维,则系统的独立性将难以得到保证,传统的整体论也将变得自相矛盾。只有发展全新的量子整体论,并在这种新的框架下去审视和建构量子系统,我们才有可能重新获得某种连贯一致的整体论。     

政府采购绩效审计应用研究 ——以郑州市为例

政府采购绩效审计是审计部门对被审计单位政府采购过程和结果进行的独立经济监督审查工作。为研究政府采购绩效审计所产生的效果,采用实地调查与分析研究相结合的方法,对郑州开展采购绩效审计的现状、审计的具体情况等进行了分析。针对现状和问题由点及面提出了健全政府采购绩效审计制度和准则、改进政府采购绩效审计采用的方式方法、完善政府采购绩效审计的反馈评价体系、完善对政府采购的监督追责机制、加强审计队伍综合素质建设等建议,以期提高政府采购绩效审计的质量和效益。

浅析《紫色》的书信体风格

《紫色》(TheColorPurple)是美国当代黑人女作家艾丽斯·沃克(AliceWalker)的代表作品之一。小说采用书信体形式,全书由92封书信构成。在小说中,艾丽斯·沃克娴熟运用现代叙述技巧,采用第一人称作为叙述人称的主线,但又不局限于第一人称,并从人物的视角进行叙述,让读者在阅读文本时,随着人物的视角,直接感受到人物的思想情绪与主观体验,从而清晰透视到女主人公茜莉从麻木、觉醒、抗争到独立的心灵感受和生活历程。本文从《紫色》的叙述技巧和主人公个性的成长两个方面分析《紫色》的书信体风格及其产生的艺术效果。     

Testing independence based on Bernstein empirical copula and copula density

In this paper we provide three nonparametric tests of independence between continuous random variables based on the Bernstein copula distribution function and the Bernstein copula density function. The first test is constructed based on a Cramér-von Mises divergence-type functional based on the empirical Bernstein copula process. The two other tests are based on the Bernstein copula density and use Cramér-von Mises and Kullback–Leibler divergence-type functionals, respectively. Furthermore, we study the asymptotic null distribution of each of these test statistics. Finally, we consider a Monte Carlo experiment to investigate the performance of our tests. In particular we examine their size and power which we compare with those of the classical nonparametric tests that are based on the empirical distribution function.     

Some novel results on pairwise quasi-asymptotical independence with applications to risk theory

In this article we obtain some novel results on pairwise quasi-asymptotically independent (pQAI) random variables. Concretely speaking, let X₁, …, X_n be n real-valued pQAI random variables, and W₁, …, W_n be another n non negative and arbitrarily dependent random variables, but independent of X₁, …, X_n. Under some mild conditions, we prove that W₁X₁, …, W_nX_n are still pQAI as well. Our result is in a general setting whether the primary random variables X₁, …, X_n are heavy-tailed or not. Finally, a special case of above result is applied to risk theory for investigating the finite-time ruin probability for a discrete-time risk model with a wide type of dependence structure.     

Robust test for independence in high dimensions

This article develops a new test based on Spearman’s rank correlation coefficients for total independence in high dimensions. The test is robust to the non normality and heavy tails of the data, which is a merit that is not shared by the existing tests in literature. Simulation results suggest that the new test performs well under several typical null and alternative hypotheses. Besides, we employ a real data set to illustrate the use of the new test.     

‘There’s a lot of places I’d like to go and things I’d like to do’: the daily living experiences of adults with mild to moderate intellectual disabilities during a time of personalised social care reform in the United Kingdom

Adult social care services in the United Kingdom have undergone a period of transformation over recent years, characterised by a drive towards personalised care. Concurrently, social care budgets have been significantly reduced. This study aimed to explore the daily living experiences of adults with mild/moderate intellectual disabilities, who are at risk of no longer meeting eligibility criteria for statutory support. Focus group discussions, which included both people with intellectual disabilities and support workers, were analysed thematically. Two broad themes are presented: independence and agency; and social capital and well-being. While some participants echoed ideas central to the personalisation narrative, a number of contextual barriers to achieving greater independence and agency were discussed. Moreover, greater independence was not a desired goal for all participants. The findings highlight the potential mismatch between personalised social care, as delivered within significant budget constraints, and the needs of adults with intellectual disabilities.     

Violence and political culture in Mozambique

This article is an attempt at developing a lens through which political culture in Mozambique can be analysed, described and interpreted. It is based on the notion of a political teleology that emerged out of the conditions within which the country fought for its independence. The paper argues that violence in a symbolic and physical form played a central role in the constitution of this political teleology by, on the one hand, allowing the liberation movement to produce an account of Mozambican history which both gave legitimacy to its own struggle while at the same time undermining alternative accounts and, on the other, set the scene for the implementation of a national project that came to be primarily concerned with the reproduction of the claim to power of the liberation movement. Forty years of independence in Mozambique offer an ideal time frame to attempt the construction of such a lens.     

Auditing biochemical research data: A case study

There is little documentation in the literature of how to conduct a data audit of laboratory research. The purpose of such an audit is to verify the extent to which the published data agree with the corresponding laboratory notebook data and whether the data thus examined appear to be sufficient to justify the published conclusions. A case study is presented, which demonstrates a step by step approach towards conducting a data audit of a published research study.
