论我国社会保障制度的公平与效率向度功能及其限度

在系统梳理学术界关于公平与效率范畴内涵及辩证关系的既有认识和研究成果的基础上,确立其在社会保障制度这一特定语境中的含义和意义,是在实践中实现公平与效率的有机统一这一设想的前提和关键。应该说,在市场经济的大潮中,公平与效率的关系主要集中体现在社会保障制度的设计和实践中,因此必须准确科学地领会和理解社会保障制度框架中的公平与效率。一方面,社会保障制度是公平的产物,但在具体的制度设计和实践实施中,也存在保障标准、范围等影响公平的因素,且从我国现行的社会保障制度在公平与效率方面的缺陷、反贫困、共同富裕和我们的现代化目标的视线看,社会保障制度的公平限度是显然的;另一方面,社会保障制度的效率包含着制度设计本身的效率及其对经济发展和社会进步作用的效率问题,因此必须科学理性地对待社会保障制度。

谈外观设计中功能与装饰的关系

产品的功能确定了产品存在的目的和价值,对外观设计专利的评价不能脱离功能。只要外观上体现功能,实现功能的具体外观特征不是唯一的,则应当考虑功能性特征。本文提出讨论外观设计特征的新角度,即功能向度与装饰向度。外观设计的目的不是纯粹的装饰和美化,功能也是外观设计的重要因素,功能和装饰应是协调统一的关系。

文化记忆与地域表达:东北少数民族题材美术的功能向度

艺术文化资源作为民族成员独特的情感表达与精神书写媒介,是表征该民族精神特质与审美取向的文化形态,对于维系民族团结、保护民族文化以及构筑民族共有精神家园具有独特意义。改革开放以来,东北少数民族美术紧跟中国美术的发展,在内容、形式、观念、语言等多个维度产生异变,逐步形成了一部粗犷豪放、静穆孤寂、刚健质朴的视觉史诗与民族图式,承载着东北地区少数民族独特的文化记忆与精神信仰。

Pure bending of simply supported circular plate of transversely isotropic functionally graded material

This paper considers the pure bending problem of simply supported transversely isotropic circular plates with elastic compliance coefficients being arbitrary functions of the thickness coordinate. First, the partial differential equation, which is satisfied by the stress functions for the axisymmetric deformation problem is derived. Then, stress functions are obtained by proper manipulation. The analytical expressions of axial force, bending moment and displacements are then deduced through integration. And then, stress functions are employed to solve problems of transversely isotropic functionally graded circular plate, with the integral constants completely determined from boundary conditions. An elasticity solution for pure bending problem, which coincides with the available solution when degenerated into the elasticity solutions for homogenous circular plate, is thus obtained. A numerical example is finally presented to show the effect of material inhomogeneity on the elastic field in a simply supported circular plate of transversely isotropic functionally graded material (FGM).

Study on size-dependent bending behavior of axially functionally graded microbeams via nonlocal strain gradient theory

Based on the nonlocal strain gradient theory(NSGT),the static bending behaviors of an axially functionally graded(AFG)Bernoulli-Euler microbeam subjected to concentrated and distributed loads are studied.The material property of the AFG microbeam changes continuously along the longitudinal direction.On the basis of the minimum potential energy principle,the equations of motion and associated classical and non-classical boundary conditions are derived.Then,Galerkin’s weighted residual method in conjunction with the normalization technique are utilized to solve the governing differential equations.The transverse deformations of the AFG microbeam suffering the sinusoidal distributed load within the framework of NSGT,nonlocal elasticity theory(NET),strain gradient theory(SGT)and classical elasticity theory(CET)are compared.It is observed that the bending flexibility of the microbeam decreases with the increase in the ratio of the material length scale parameter to the beam height.However,the bending flexibility increases with the increase in the material nonlocal parameter.The functionally graded parameter plays an important role in controlling the transverse deformation.This study provides a theoretical basis and a technical reference for the design and analysis of AFG micro-beams in the related regions.

Asymmetric Green's functions for exponentially graded transversely isotropic substrate–coating system

By virtue of a complete set of two displacement potentials,an analytical derivation of the elastostatic Green’s functions of an exponentially graded transversely isotropic substrate–coating system is presented.Three-dimensional point–load and patch–load Green’s functions for stresses and displacements are given in line-integral representations.The formulation includes a complete set of transformed stress–potential and displacement–potential relations,with utilizing Fourier series and Hankel transforms.As illustrations,the present Green’s functions are degenerated to the special cases such as an exponentially graded half-space and a homogeneous two-layered half-space Green’s functions.Because of complicated integrand functions,the integrals are evaluated numerically and for numerical computation of the integrals,a robust and effective methodology is laid out which gives the necessary account of the presence of singularities of integration.Comparisons of the existing numerical solutions for homogeneous two-layered isotropic and transversely isotropic half-spaces are made to confirm the accuracy of the present solutions.Some typical numerical examples are also given to show the general features of the exponentially graded two-layered half-space Green’s functions that the effect of degree of variation of material properties will be recognized.
