农民工“脱贫”新解

摘我国进城的农民工越来越多，在城市中他们属于贫困群体，脱贫是农民工面临的重要课题。传统观点认为脱贫就是指摆脱经济上的贫困；我认为农民工“脱贫”应是社会权利贫困问题的解决，且根本途径在于：创新制度公正地对待农民，即给农民工公正的社会权利，并使农民工现有的权利得到有效的贯彻执行，关键是给农民工参与社会“游戏规则”的制订的公平机会。因此，我们要根据制度公正的基本理念，给农民工以公平、公正的社会权利，农民工才能真正脱贫。     

中国底层群体的社会上升之路

从公平和建立和谐社会的价值目标出发,探讨底层群体向上流动的社会机制.认为底层群体的上升既需要个人的努力,更需要社会制度层面的改革.从制度上打破城乡分割的二元社会的户籍制度,给农民工提供真正的国民待遇,加快城市产业化调整,增加教育公平的机会,是提升底层社会群体上升机会的有效途径.     

论公民社会权利视野下的农民工社会保障问题

引入国外的公民社会权利理论,作为分析完善我国农民工社会保障制度的学理基础,要求我们通过制度创新,给农民工以平等的国民待遇,落实公民的迁徙自由,扩展农民工的社会权利,解决农民工社会保障制度缺失问题。     

建立农民工最低生活保障制度的必要性分析

当前,政府越来越重视“三农”问题,关注农民工的生存状况,全国许多城市已经为在辖区范围内工作的农民工建立了有针对性的社会保障制度,但是,作为城镇社会保障体系的重要组成部分的“最低生活保障制度”仍然把外来农民工排除在外。农民工的贫困问题不容忽略。如果政府继续漠视外来农民工贫困问题,则有可能导致贫富差距过于悬殊,损伤了社会公正原则,     

当代社会公正初探

公正作为一种道德价值观念和给人应得(包括利害、奖与惩)的一种行为准则，包括社会公正和个人公正。它具有历史性和客观性两大特征。公正原则包括权利和义务对等原则、机会平等原则、按贡献分配原则等。就我国目前的社会主义初级阶段而言，社会公正的基本要求是：在经济上坚持按劳分配为主，多种分配形式并存的分配原则；在政治上保障社会成员和劳动平等地行使各项权利；在发展机会上实行公平竞争；把公平与效率结合起来，效率优先，兼顾公平。     

高校贫困生"心理脱贫"问题研究

当前,在我国高等教育的发展进程中,存在许多急需解决的问题,其中大学生贫困问题已经成为各大高校关注的焦点问题.附着于物质贫困,强烈的自卑感,极度敏感、脆弱的自尊心,拘谨压抑的性格,尴尬的人际关系,因期望值过高而产生的学业压力等因素引发了心理问题.贫困生已由单纯物质的贫困转变为物质、心理的"双因生".对此,应该引起社会及教育界的高度关注,要在解决物质脱贫的同时,实现"心理脱贫".     

论对农民工权利的制度保护

农民工的权利保护问题已经越来越成为社会关注的焦点,也是当今中国社会转型时期所面临的不可回避且急待解决的问题。针对农民工权利问题的现状,从户籍管理制度、就业制度、社会保障制度等制度层面上如何保护农民工权利进行论述,以期尽快实现对农民工权利的保护和救济。     

完善流动人员的社会保障制度初探

随着市场经济发展,以农民工为主体的流动人员大量涌现,既解决了企业劳动力缺乏的困难,也为城市建设和经济发展作出了巨大贡献.但是流动人员社会保障制度尚未健全,给社会带来了一些不稳定因素.社会保障制度是社会经济发展的“稳定器”,进一步完善流动人员的社会保障制度,实现社会公平,是当前亟待解决的问题.     

统筹城乡背景下城乡居民公正发展思考——学习党的十七届三中全会《决定》体会

统筹城乡发展不仅是要统筹实现城乡经济社会的协调发展,更为重要的是,要统筹实现城乡居民的公正发展。城乡居民的公正发展就是要实现城乡居民发展的权利公平、发展的机会公平、发展的规则公平、发展的成果分配公平等。     

再谈教育公平的内涵

公平是评价社会制度的一种道德标准,教育公平作为社会公平的重要组成部分,是社会公平在教育领域的延展和体现,应当是每个社会成员在享受公共教育资源时受到公正和平等的对待,包括教育权利的平等与教育机会的均等两个有机的组成部分。     

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3～4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰～ -7.8‰, PDB) and matrix dolomites (-6.6‰～ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084～0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078～0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.

An Index mechanism for multi-scale view in spatial databases

There are numerous geometric objects stored in the spatial databases. An importance function in a spatial database is that users can browse the geometric objects as a map efficiently. Thus the spatial database should display the geometric objects users concern about swiftly onto the display window. This process includes two operations:retrieve data from database and then draw them onto screen. Accordingly, to improve the efficiency, we should try to reduce time of both retrieving object and displaying them. The former can be achieved with the aid of spatial index such as R-tree, the latter require to simplify the objects. Simplification means that objects are shown with sufficient but not with unnecessary detail which depend on the scale of browse. So the major problem is how to retrieve data at different detail level efficiently. This paper introduces the implementation of a multi-scale index in the spatial database SISP (Spatial Information Shared Platform) which is generalized from R-tree. The difference between the generalization and the R-tree lies on two facets: One is that every node and geometric object in the generalization is assigned with a importance value which denote the importance of them, and every vertex in the objects are assigned with a importance value,too. The importance value can be use to decide which data should be retrieve from disk in a query. The other difference is that geometric objects in the generalization are divided into one or more sub-blocks, and vertexes are total ordered by their importance value. With the help of the generalized R-tree, one can easily retrieve data at different detail levels.Some experiments are performed on real-life data to evaluate the performance of solutions that separately use normal spatial index and multi-scale spatial index. The results show that the solution using multi-scale index in SISP is satisfying.     

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that     

On the Thermodynamic Limit for Responses to Static Electromagnetic Fields

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the
