A New Approach to Measurement of Regional Inequality in Particular Directions

Regional inequality is a core issue in geography,and it can be measured by several approaches and indexes.However,the global inequality measures can not reflect regional characteristics in terms of spatiality and non-mobility,as well as correctly explore regional inequality in particular directions.Although conventional between-group inequality indexes can measure the inequality in particular directions,they can not reflect the reversals of regional patterns and changes of within-group patterns.Therefore,we set forth a new approach to measure regional inequality in particular directions,which is applicable to geographic field.Based on grouping,we established a new index to measure regional inequality in particular directions named Particular Direction Inequality index(PDI index),which is comprised of between-group inequality of all data and between-group average gap.It can reflect regional spatiality and non-mobility,judge the main direction of regional inequality,and capture the changes and reversals of regional patterns.We used the PDI index to measure the changes of regional inequality from 1952 to 2009 in China.The results show that:1) the main direction of China's regional inequality was between coastal areas and inland areas;the increasing extent of inequality between coastal areas and inland areas was higher than the global inequality;2) the PDI index can measure the between-region average gap,and is more sensitive to evolution of within-region patterns;3) the inequality between the northern China and the southern China has been decreasing from 1952 to 2009 and was reversed in 1994 and 1995.

Sources of Particular Pollutants inAmbient Air at a Petrochemical Enterprise

The study on source apportionment of particular pollutants in ambient air at a petrochemical enterprise is the ba-sis of the control over air pollution. Through analyzing particular pollutants in the samples collected from one petrochemi- cal enterprise in northwestern China, the sources of particular pollutants were discussed. The test results showed that con- centrations of particular pollutants in different sites were remarkably different. Results showed that the sampling sites with higher concentrations of particular pollutants, including toluene, xylenes, NH3 and H2S, were located at the boundary of the petrochemical enterprise. Instead, the concentrations of NMHC in the ambient air sampling sites were higher than those at the boundary of the petrochemical enterprise. The sampling sites with higher concentrations of particular pollutants were located in the area that was close to the petrochemical enterprise. The results obtained from the Pearson correlation co- efficients analyses, the factor analyses, and x^2-tests of the particular pollutants had revealed that NH3, H2S, toluene and xylenes at all sampling sites came from the same source, while NMHC might come from some other sources besides the petrochemical enterprise.

Moral Generalism or Particularism？

Moral generalism and particularism are two positions in meta-ethics which have different views regarding the relation between moral thought and principles. By accepting this relationship, generalists emphasize the necessity of principles in decision making process, and claim that the rationality of moral thought depends on the provision of a suitable supply ofmoral principles. In contrast, particularists have rejected, or at least doubted, the existence of moral principles, and believe that the rationality of moral thought depends on recognizing special features of a case and relevant conditions. This is why, unlike generalists, they use case study method rather than syllogism in decision making process and moral judgment. Consequently, to support their view, particularists commonly resort to holism in the theory of reasons, while atomism is in support of generalism. To evaluate these two attitudes, this study surveys some arguments that particularists and generalists proposed to justify their view and criticize the rival＇s one, and also explains their positions concerning the epistemological and metaphysical role of moral principles and reasons. Finally, after evaluating their claims, the importance of both approaches in meta-ethics is stressed.

Optimal Deployment with Self-Healing Movement Algo-rithm for Particular Region in Wireless Sensor Network

Optimizing deployment of sensors with self-healing ability is an efficient way to solve the problems of cov-erage, connectivity and the dead nodes in WSNs. This work discusses the particular relationship between the monitoring range and the communication range, and proposes an optimal deployment with self-healing movement algorithm for closed or semi-closed area with irregular shape, which can not only satisfy both coverage and connectivity by using as few nodes as possible, but also compensate the failure of nodes by mobility in WSNs. We compute the maximum efficient range of several neighbor sensors based on the dif-ferent relationships between monitoring range and communication range with consideration of the complex boundary or obstacles in the region, and combine it with the Euclidean Minimum Spanning Tree (EMST) algorithm to ensure the coverage and communication of Region of Interest (ROI). Besides, we calculate the location of dead nodes by Geometry Algorithm, and move the higher priority nodes to replace them by an-other Improved Virtual Force Algorithm (IVFA). Eventually, simulation results based-on MATLAB are presented, which do show that this optimal deployment with self-healing movement algorithm can ensure the coverage and communication of an entire region by requiring the least number of nodes and effectively compensate the loss of the networks.

The Quantitative Instability of Non-linearity System and the Particularity of Information

The present paper tries to discuss the quantity instability in the non-linearity dynamics equations without the limit of the stability in the dynamics equations. The result shows that the quantity instability of non-linearity can be deducted to the turning transformation in the curvature space. “The dynamics of varying acceleration" is not the issue of inertia system in science of the time. The particularity as information cannot limit the quantity instability with the quantity stability in inertia system. The particular information does have the significant meaning related to the turning transformation in evolution, in which each problem of non-linearity or matter evolution can go out of the inertia system by means of “kill three birds with one stone".

The Method of Polynomial Particular Solutions for Solving Nonlinear Poisson-Type Equations

In this paper,the method of polynomial particular solutions is used to solve nonlinear Poisson-type partial differential equations in one,two,and three dimensions.The condition number of the coefficient matrix is reduced through the implementation of multiple scale technique,ultimately yielding a stable numerical solution.The methodological process can be divided into two main parts:first,identifying the corresponding polynomial particular solutions for the linear differential operator terms in the governing equations,and second,employing these polynomial particular solutions as basis function to iteratively solve the remaining nonlinear terms within the governing equations.Additionally,we investigate the potential improvement in numerical accuracy for equations with singularities in the analytical solution by shifting the computational domain a certain distance.Numerical experiments are conducted to assess both the accuracy and stability of the proposed method.A comparison of the obtained results with those produced by other numerical methods demonstrates the accuracy,stability,and efficiency of the proposed method in handling nonlinear Poisson-type partial differential equations.

论国际关系研究的知识属性——兼论西方国际关系研究的内在缺陷

现代国际关系研究经历百年发展历程之后,正面临着新的机会和选择,需对其基本属性进行重新定位和认识。国内政治与国际关系在本体论层面上的差异决定了政治学与国际关系研究在方法论意义上的根本性差异,国家这个分析单元的个体性而非一般性特征是国际关系研究必须关注的重点。对“科学化”的过分追求可能导致国际关系研究陷入体系性和实践性之间的矛盾,对国际关系研究而言,任何追求简单性、普遍性和体系性的方法可能都未必真正有效,能够切合国际关系实际的,也许是一种更注重复杂性、个体性和特殊性的方法。国际关系研究中找回特殊性应加强对历史研究的关注和对社会研究的借鉴,并注重对文化和价值问题的分析。国际关系的知识应该是一种同时面向个体性、可变性和可能性并高度关注文化和价值因素的知识,既包括传统意义上的科学面向,也需要有新的追求,即降低国家行为的不确定性并探讨国家行为的可能性。这种追求,应该能够为国际关系研究开掘更广阔且更具实效性的空间。

几种特殊火山碎屑岩的形成机制及研究意义

火山碎屑岩是火山物理学研究的最直接对象,也是鉴别碎屑化过程最重要的研究对象。一些特殊类型的火山碎屑岩及相关岩石往往可以反映出某些特征的火山岩浆作用过程,这正是甄别不同类型火山灾害发生概率的基本依据。火山灾害是与火山和火山喷发有关的灾害,它是人类在自然界面临的最重要的灾害类型之一。火山灾害与火山喷发类型直接相关,其中的爆破性火山喷发则可以形成最为致命的强烈火山灾害。爆破性火山喷发的直接产物是形成各式各样的火山碎屑岩,它们代表了喷发过程所带来的不同类型与强度的火山灾害。原生火山碎屑与次生碎屑反映了火山喷发期与喷发间歇期火山表面过程的差异,而岩浆喷发、射汽岩浆喷发和射汽喷发堆积物的鉴定则标志了现代火山学研究的系统性深化,它们是从事火山灾害研究的先导性工作。细粒空降火山灰在水盆地里保存的火山灰纹层因其良好的等时面与环境指示意义而受到人们的重视,与其伴生的岩石则可能需要区分层凝灰岩、沉凝灰岩、凝灰质泥岩等各种不同火山沉积作用类型。熔岩流动碎屑化产生的自碎角砾岩和熔岩流水下淬火形成的碎玻熔岩代表了与熔岩流直接相关的碎屑化,而不是与爆破性火山作用相关的碎屑化。通常把它们划归为原生火山作用碎屑,但其灾害意义却完全不同。不同类型的火山碎屑岩形成于不同的碎屑化机理与成岩方式,其中一些特定的火山碎屑岩更是代表了极为特殊的火山灾害类型与规模。对于隐爆角砾岩,尽管它是一种火山碎屑岩的岩石名称,但其实我们更关心它的资源经济学意义。
