税费改革后乡镇财政运行的困境与对策

农村税费改革对乡镇财政收入的消减效应明显,对增加乡镇财政收入的替代效应较弱;农村税费改革使乡镇财政困难等原有问题充分暴露出来,进一步扩大了乡镇财政的不平衡,使乡镇财政正常运转更加困难;要使乡镇财政走向良性运转轨道,就必须完善地方财政管理体制,完善财务管理机制,加大力度培植乡镇税源,转变乡镇政府职能,建立合理的公共管理体制。     

Problem of the free oscillations of a capillary bridge

The free oscillations of a capillary bridge whose equilibrium shape is determined by the surface tension forces and the static gravity field are investigated. The values of 25 “lower” levels of the spectrum of natural oscillations of the capillary bridge are found for various control parameters in accordance with the experimental conditions.     

Voltammetric determination of mesotrione at hanging mercury drop electrode

A study of the electrochemical reduction of the mesotrione pesticide on a hanging mercury drop electrode (HMDE) was performed as a basis for the development of a sensitive analytical method for natural samples. The electrochemical characteristics of herbicide mesotrione dissolved in a phosphate buffer (pH 7.0) have been determined by means of electrochemical techniques such as cyclic voltammetry (CV) and differential pulse voltammetry (DPV) over a wide range of pH from 2.0 to 10.0. The experimental parameters, such as electrolyte type and its pH, pulse amplitude, and scan rate were optimized. The method was applied to the determination of the pesticide in a spiked soil samples. Using this method, a linear calibration curve for mesotrione was obtained up to the 0.1 μM range in pH 7 phosphate buffer solution with a detection limit (S/N = 3) of 50 nM. The method can be applied successfully to the determination of mesotrione in soils. The text was submitted by the authors in English.

政治态度教育是思想政治教育的重要内容,它直接影响思想政治教育的效果。当前我国大学生政治态度教育的效果如何?本文通过对江西省四所高校的调查,分析了当前大学生政治态度教育效果的现状,并认为,对大学生加强以政治态度教育为内容的思想政治教育对提高大学生的思想政治教育水平具有重要的意义。     

论国家对农民工群体的政策缺失

伴随着国家城市化和工业化进程的加快，农民工成为一个越来越受人们关注的群体。在我国以户籍制为基础的城乡二元结构下，农民工有着非常复杂的身份，他们生活、工作并居住在城市，但是他们的户籍在农村。在我国，社会福利保障制度是以户籍制为基础划分的，这样特殊的背景导致了农民工群体在很多方面被排除在社会福利保障制度之外。目前，我国正在积极构建社会主义和谐社会，在这个大背景的感召下，农民工群体作为和谐社会的一个特殊群体，对他们的社会政策有待进一步完善。本文分析了农民工群体在医疗保险、用工制度、子女教育等方面的政策缺失，并提出了相应的政策建议。

Epi-Convergence and Lower and Epi-Upper Semicontinuous Approximations in Distribution

The paper introduces an extension of the epi-convergence, the lower semicontinuous approximation and the epi-upper semicontinuous approximation of random real functions in distribution. The new notions could be helpful tools for sensitivity analyzes of stochastic optimization problems. The research is evoked by S. Vogel and continues the research started by Vogel and the author.     

A Law of Large Numbers for the Zeroes of Heine–Stieltjes Polynomials

We determine the limiting density of the zeroes of Heine–Stieltjes polynomials (or of any set of points satisfying the conclusion of Heine–Stieltjes Theorem) in the thermodynamic limit and use this to prove a strong law of large numbers for the zeroes.
