The model follows the theory previously proposed by Chen Q S. In the model, firstly, the author establishes the attribute space matrix and determines the weight based on Shannon entropy theory; secondly, calculates attribute measure; thirdly, evaluates that with confidence criterion and score criterion; finally, an application example is given. The results show that the water quality of the groundwater sources for the city comes up to the grade II or III standard. There is no pollution that obviously exceeds the standard and the water can meet people’s needs .The results from an evaluation of this model are in basic agreement with the observed situation and with a set pair analysis (SPA) model.展开更多

When a woman dies, in most African societies, her legacy is usually inherited by the husband, children, and her family. But if a man dies, the widow, usually experiences false accusations of killing her husband to deny her share of her husband's properties. This paper examines how the dynamics of cultural practices in Nigeria promotes abuse of inheritance rights of women and discusses the possibilities of using Islamic inheritance rules as a divine solution to the abuse of inheritance rights of women. The research questions as follows: what is the nature of women's rights to father's estate? What is the nature of widow's right to the husband's estate? What is your perception about the Islamic law of inheritance? The data for this study were collected using questionnaire and simple percentage was used for the analysis. In this respect, a questionnaire was administered to 220 women who were purposely selected from the three major tribes in Lagos state, Nigeria. The result showed that various cultures in Nigeria favour male child, grant male higher rights to land and other properties and promote abuse of inheritance rights against women.展开更多

However, large numbers of experiments indicate that the value of weight vector has no relativity to its initial value but depends on the data of Quality Standard and actual samples. In the present study, the ARM is enhanced with the technique of data driving, which means some more groups of data from the Quality Standard are selected with the uniform random method to make the calculation of weight values more rational and more scientific. This improved attribute recognition model (IARM) is applied to a real case of assessment on seawater quality. The given example shows that the IARM has the merits of being simple in principle, easy to operate, and capable of producing objective results, and is therefore of use in evaluation problems in marine environment science.展开更多

In this paper, the influence of entrepreneurs' political connection on the M&A driving factors and M&A efficiency of the enterprises with different property rights are analyzed using 357 mergers and acquisitions of China' s 189 listed companies in 2005-2011 as samples based on the distinction between political connection and the nature of enterprise property rights. The results show that the political connection plays a very significant positive influence on the M&A performances of the central state-owned enterprises and private enterprises, but exerts a very significant negative influence on the local state-owned enterprises; the intensity of entrepreneurs' political connection also plays a certain influence on enterprise merger and acquisition, and the central political connection and the local political connection are significantly different in the influence on the enterprise M&A performance.展开更多

It argues that Faulkner represents her as "the mother as a monster" and looks at the features of that representation. More specifically, the paper devotes attention to this abusive mother's curious masculinity, employing feminist readings from two angles. That is, on the one hand, the paper reexamines the nature of Mrs. Gant's unfemininity by considering the immense responsibility of child-rearing that mothers bear in modern societies. On the other hand, it attempts to locate the origin of her bodily manliness by considering the prism of images of women as evil and destabilizing that pervaded Western culture early in the twentieth century. Such approaches have revealed that making a monster of a mother requires a conspiracy taking advantage of both the inconsistencies inherent in the ideals of motherhood and the bizarre processes through which femininity itself is masculinized. In conclusion, this paper argues that Mrs. Gant's monstrosity is a reflection of a predicament which many women in modern times whether Faulkner's or our own share, that is, being expected to be a perfect mother while still being viciously castigated as sexually threatening.展开更多

Then we study some approximation properties of these operators. We give some inequalities for these operators by means of the weighted modulus continuity and also obtain a Voronovskaya-type theorem. Furthermore, in our paper show that the operators give better degree of approximation of functions belonging to weighted spaces than classical Szaisz- Kantorovich operators.展开更多

Revealing the spatiotemporal pattern of urban expansion and spatiotemporal relationships with driving forces, especially in terms of the ubiquitous and fast growing small city, is a crucial prerequisite to solving these problems and realizing sustainable development. Kunshan, China was used as a case study here. Eleven variables from four aspects covering physical, socioeconomic, accessibility and neighborhood were selected, and logistic regression and geographically weighted logistic regression modeling were employed to explore spatiotemporal relationships from 1991-2014. Results reveal that urban expansion in Kunshan shows an accelerating tendency with annual expansion from 2000-2014 four times higher than for 1991-2000. More importantly, the annual expansion rate of Kunshan of 28.42% in 2000-2014 is higher than that of a large city. Urban expansion and related factors have spatiotemporal varying relationships. From a global perspective, the closer to a city, town, main road and the higher the GDP, the more likely a region will undergo urbanization. Interestingly, the effect of population on urban expansion is decreasing, especially in developed areas, and the effect of distance to lake is enhanced. From a local perspective, the magnitude and even the sign of the coefficients vary across the study area. However, the range of the coefficient of GWLR is around that of the corresponding variable in LR, and the sign of most variables in GWLR is consistent with that of corresponding variables in LR. GWLR surpasses LR with the same explanatory variables in revealing regional differences and improving model reliability. Based on these findings, more attention should be given to small cities in China. Promoting the connotation of city culture and public services to realize New-type Urbanization and regional diversity policy in order to manage urban expansion scientifically are also recommended.展开更多

The issue can thus be framed in another way, as the issue of the appearance in court of the necessary witnesses. Here, the defendant's right to confront is the key point. Since neither China's criminal procedural law nor corresponding judicial interpretations have granted the defendant the right to confront, the rate of appearance of the necessary witnesses amounts in practice to only about twenty- five percent. Criminal trials conducted in the absence of the right to confrontation usually conform to the doctrine of positive substantive truth and manifest a lack of care in conviction and sentencing as well as reliance on a single source of legitimacy in reaching judgments. To correct this state of affairs, it is necessary to institute the right to confront and corresponding safeguards.展开更多
