论循环经济中的生产者责任延伸制度

循环经济是一种节约能源、促进资源的高效利用并减少环境污染的经济发展模式。生产者责任延伸制度是循环经济立法的基本制度之一。我国当前已经通过立法正式确立了生产者责任延伸制度,但可操作性不强,有必要继续完善相关配套措施,进一步落实生产者责任延伸制度,以更好的实现环境友好型社会。

证人出庭作证“必要性条款”解释适用研究

证人出庭与否不仅关系到案件事实真相的准确查明,还直接关系到被告人辩护权利能否得到充分的尊重和保障。通过对420份裁判文书的梳理可以发现,人民法院在证人“有必要出庭”条款的适用上,主要关注事实认定的准确性,而对被告人诉讼权利缺乏应有的关照。在权利保障已成为刑事司法主流话语的今天,有必要“以对质权为中心”对该条款进行规范解释。但在个案适用过程中,为了实现证人出庭背后多重法益的动态平衡与相对稳定,对质权的行使应当具有一定的灵活性。在控辩双方提出实质异议的情况下,法官原则上应当允许证人出庭,即使在例外情形下认为“没有必要出庭”,也应提供令人信服的理由。为此,需要在比例原则的基本框架下,对人民法院认为“证人没有必要出庭”的充分理由进行类型化建构,以最大限度地保障公正审判的实现。

浅谈安全管理的职责

同时还要协助领导推动企业的安全管理工作,贯彻执行安全管理工作中的各项政策法令和规章制度;经常进行现场检查,并协助各级领导解决生产过程中的安全问题;制定文明施工实施细则,并负责监督检查现场有害物质的安全储存以及固体废弃物的安全存放及处理;指导生产班组的安全员工作;总结和推广安全生产先进经验,对职工进行安全生产宣传教育等,这些都是安监员需要做的事情,是我们安监员的职责。安监员做的每一件事情都是为了保证安全,无论是企业自身的安全,还是职工的生命安全,都要得到最大的保障。化工厂接触的都是一些有毒的气体或是腐蚀性很强的液体,职工在作业时格外小心,但还是难免会出现一些意外,例如机器设备的原因,年久失修或是平时维护的不好,或是职工的安全意识不强,导致事故的发生。对职工进行安全生产宣传教育是非常有必要的,这也是安监员一个重要的职责。

金融市场风险的规避与控制策略研究

随着经济的快速发展，上海市日益重视金融领域的安全运行，通过设立相应的法规，来逐渐的实行金融风险与交叉性金融业务监管的制度化。如在市政府的组织下，上海市先后制定了《上海市金融安全工作总体框架》与《上海市金融风险预警处置预案》。相信上海所采取的这些措施，一定会为经济的健康稳定发展提供很好制度支持，并为上海及时有效地规避与控制金融市场风险提供很好的制度保障。

A Concept Analysis of Continuity of Care in Nursing

Purpose： This paper is a report about the concept analysis of continuity of care, to get further understanding of continuity of care. Methods： The Walker and Avant concept analysis approach was applied in this paper. Results： The three attributes include： seamless transfer, flexible reaction and effective interaction. The antecedents were changed needs and patient centred care. In addition, the continuity of care had a significant effect on patients’ outcome, satisfaction and costs. Conclusions： This analysis provides nurses an understanding about continuity of care in both patient’s and care provider’s perspective. Continuity of care is a tailored services provided by care givers, which is an essential element of healthcare system.

教育中科学的惩戒不可少

在当前深化教育改革的新形势下，赏识教育固然重要，但光靠赏识表扬是远远不够的。适时地采用科学的惩戒手段也是很有必要的。

Some classes of complete permutation polynomials over Fq

By using a powerful criterion for permutation polynomials, we give several classes of complete permutation polynomials over finite fields. First, two classes of complete permutation monomials whose exponents are of Niho type are presented. Second, for any odd prime p, we give a sufficient and necessary condition for a-1xdto be a complete permutation polynomial over Fp4 k, where d =(p4k-1)/(pk-1)+ 1 and a ∈ F*p4k. Finally, we present a class of complete permutation multinomials, which is a generalization of recent work.

Best constants for Hausdorf operators on n-dimensional product spaces

In this paper, we study certain Hausdorff operators in the high-dimensional product spaces. We obtain their power weighted boundedness from Lp to Lq and characterize the necessary and sufficient conditions for their boundedness on the power weighted Lp spaces. Moreover, in the case p = q, we obtain the sharp bound constants.

Stochastic H_2/H_∞ Control for Poisson Jump-Diffusion Systems

This paper is concerned with stochastic H_2/H_∞ control problem for Poisson jump-diffusion systems with(x, u, v)-dependent noise, which are driven by Brownian motion and Poisson random jumps. A stochastic bounded real lemma(SBRL for short) for Poisson jump-diffusion systems is firstly established, which stands out on its own as a very interesting theoretical problem. Further, sufficient and necessary conditions for the existence of a state feedback H_2/H_∞ control are given based on four coupled matrix Riccati equations. Finally, a discrete approximation algorithm and an example are presented.

TOEPLITZ ALGEBRAS ON DISCRETE GROUPS AND THEIR NATURAL MORPHISMS

Let G be a discrete group, E1 and E2 be two subsets of G with E1 () E2, and e ∈ E2. Denote by TE1 and TE2 the associated Toeplitz algebras. In this paper, it is proved that the natural morphism γE2,E1 from TE1 to TE2 exists as a C*-morphism if and only if E2 is finitely covariant-lifted by E1. Based on this necessary and sufficient condition, some applications are made.

Weighted Inequalities for the Generalized Maximal Operator in Martingale Spaces

The generalized maximal operator .44 in martingale spaces is considered. For 1 〈 p ≤ q 〈 ∞, the authors give a necessary and sufficient condition on the pair （μ, v） for M to be a bounded operator from martingale space L^P（μ） into L^q（μ） or weak-L^q（μ）, where μ is a measure on Ω × N and v a weight on Ω. Moreover, the similar inequalities for usual maximal operator are discussed.

Orientation-preservation conditions on an iso-parametric FEM in cavitation computation

The orientation-preservation condition, i.e., the Jacobian determinant of the deformation gradient det Vu being required to be positive, is a natural physical constraint in elasticity as well as in many other fields. It is well known that the constraint can often cause serious difficulties in both theoretical analysis and numerical computation, especially when the material is subject to large deformations. We derive a set of necessary and sufficient conditions for the quadratic iso-parametric finite element interpolation functions of cavity solutions to be orientation preserving on a class of radially symmetric large expansion accommodating triangulations. The result provides a practical quantitative guide for meshing in the neighborhood of a cavity and shows that the orientation-preservation can be achieved with a reasonable number of total degrees of freedom by the quadratic iso-parametric finite element method.

Rational maps as Schwarzian primitives

We examine when a meromorphic quadratic differential φ with prescribed poles is the Schwarzian derivative of a rational map. We give a necessary and sufficient condition: In the Laurent series of φ around each pole c, the most singular term should take the form(1- d2)/(2(z- c)2), where d is an integer, and then a certain determinant in the next d coefficients should vanish. This condition can be optimized by neglecting some information on one of the poles(i.e., by only requiring it to be a double pole). The case d = 2 was treated by Eremenko(2012). We show that a geometric interpretation of our condition is that the complex projective structure induced by φ outside the poles has a trivial holonomy group. This statement was suggested to us by Thurston in a private communication. Our work is related to the problem of finding a rational map f with a prescribed set of critical points, since the critical points of f are precisely the poles of its Schwarzian derivative.Finally, we study the pole-dependency of these Schwarzian derivatives. We show that, in the cubic case with simple critical points, an analytic dependency fails precisely when the poles are displaced at the vertices of a regular ideal tetrahedron of the hyperbolic 3-ball.
