Erdős–Gallai-type results for colorful monochromatic connectivity of a graph

A path in an edge-colored graph is called a monochromatic path if all the edges on the path are colored with one same color. An edge-coloring of G is a monochromatic connection coloring (MC-coloring, for short) if there is a monochromatic path joining any two vertices in G. For a connected graph G, the monochromatic connection number of G, denoted by mc(G), is defined to be the maximum number of colors used in an MC-coloring of G. These concepts were introduced by Caro and Yuster, and they got some nice results. In this paper, we study two kinds of Erd?s–Gallai-type problems for mc(G), and completely solve them.     

Area Deprivation and Liver Cancer Prevalence in Shenzhen,China: A Spatial Approach Based on Social Indicators

Cancer has become an alarming threat to human health and well-being worldwide. Examining the social determinants of cancer prevalence should effectively inform the practices and strategies on cancer treatment and prevention. However, rather few studies have conducted in this regard for developing countries. This paper attempts to characterize the association between area deprivation and liver cancer prevalence using a case of Shenzhen, China. Data from 2009 to 2011 provided by Shenzhen’s Health Information Center are used to calculate the incidence rate of liver cancer at district level. An area deprivation index (ADI) at district level is established by integrating 13 indicators of 5 domains (income, employment, education, housing and demography). The weight for each indicator is determined by two typical subjective methods (AHP and fuzzy AHP) and two common objective methods (Entropy and Coefficient Variation). Quantitative comparisons indicate that the four methods are highly consistent though they assign different weight to the indicators. Spatial lag regression identifies significantly positive linear relationships between ADIs and liver cancer incidence rate from 2009 and 2010. It suggests that greater possibility of liver cancer prevalence would be expected in districts of higher social deprivation. The results also denote that the obtained relationships are insensitive to weight determination method and temporal dimension. Our study demonstrates that spatial autocorrelation should be incorporated for better understanding the association between area deprivation and liver cancer prevalence at district level. This paper provides some new insights into social indicators research.     

Area Social Deprivation and Public Health: Analyzing the Spatial Non-stationary Associations Using Geographically Weighed Regression

The prevalence of non-communicable chronic diseases (NCDs) worldwide poses an alarming threat to public health. Recent literature has embraced the opinion that incorporating the social factors should advance the understanding of NCDs prevalence. In this context, examining the NCDs prevalence in association with area social deprivation should provide critical implications for coping with public health risks. However, few empirical studies have examined this specific issue, especially in the developing countries. Using the principal component analysis, an area social deprivation index (ASDI) is established for the Shenzhen city (China) by integrating ten indicators from four dimensions: education, housing, socially disadvantaged population, and economically disadvantaged population. The geographically weighted regression (GWR) is employed to analyze the associations between ASDI and the incidence rate of three prevalent NCDs at district scale. Spatial non-stationary relationships are identified for the three diseases. More specifically, prevalence of the three diseases is all positively correlated with the ASDI. Strength of the associations presents the geography that it generally decreases from the central city to the suburb. These findings suggest that greater possibility of NCDs prevalence would be expected in districts with higher social deprivation. Besides, the impact of social deprivation on NCDs prevalence is much stronger in the central city. The spatial stationarity can facilitate the formulation of location-specific preventive measurements. This paper is believed to provide an innovative insight for social indicators research.     

散与凝聚:“世界温州人”文化认同的独特性

“世界温州人”概念来源于温州文化软实力研究语境.其文化认同的独特性表现为:价值取向是回溯文化母体,从内外温州人互动中凝聚区域发展的民心;构成地域文化“离散”后认同的文化力是内驱力和危机感并存的;地域文化“凝聚”效应需要确立范畴化概念,利用温州地域文化的潜能,培育“案例温州”,增强认同效应;同时还必须保持“根文化对策”和“在地化”文化认同的统一,以维护世界温州人的国际形象.

China's Below‐Replacement Fertility: Government Policy or Socioeconomic Development?

The article challenges the notion that below-replacement fertility and its local variation in China are primarily attributable to the government's birth planning policy. Data from the 2000 census and provincial statistical yearbooks are used to compare fertility in Jiangsu and Zhejiang, two of the most developed provinces in China, to examine the relationship between socioeconomic development and low fertility. The article demonstrates that although low fertility in China was achieved under the government's restrictive one-child policy, structural changes brought about by socioeconomic development and ideational shifts accompanying the new wave of globalization played a key role in China's fertility reduction.     

大学录取资格可以拍卖吗？——对不同伦理学流派赞同与反对理由的比较

从亚里士多德的公正理论来看,拍卖大学录取资格破坏了大学的目的,使不具备相应德行的人占据了上大学的机会,因而是错误的;社群主义可能从破坏了共同善的角度也反对拍卖;自由主义从大学的权利角度赞同拍卖。罗尔斯则认为,只要满足差异原则,拍卖就是公正的。多元集体主义从社会功利优化原则出发给出了拍卖大学录取资格的条件。     

形成性评价的研究现状与发展趋势——以中国学术期刊网络出版总库为样本来源

形成性评价强调教学中学生的主体地位,关注学习过程,重视教学反馈,其优越性已经毋庸置疑。通过采用统计学方法,以中国知网的中国学术期刊网络出版总库上的学术论文为研究对象,从多维度分析国内形成性评价研究存在的问题,据此提出发展建议。研究发现:形成性评价研究整体上呈上升趋势;实证类研究较少;高校教学研究较多,其他层面教学研究相对薄弱;评价对象和目的研究较多,评价方式研究较少;大学英语研究占绝大多数,专业英语较少;重复性研究较多,结论雷同,研究水平有待提高。     

关于改进和加强教育科学研究的几点思考

教育科学是哲学社会科学的重要组成部分,进一步改进和加强教育科学研究,是繁荣哲学社会科学的当务之急,改进和加强教育科学研究,必须坚持"三个服务",即为教育宏观决策科学化、民主化服务,为教育改革和发展的实践服务,为繁荣教育科学服务。同时,要加强以校为本的实践教育学研究,为基础教育课程改革服务。     

教育在社会经济发展中的作用

本文从理论上阐述了为什么世界各国政府、社会中的大多数家庭都向教育投资,这是因为教育具有两类利益内在利益与外溢利益.前者由接受教育的本人享受,因此投资教育的回报是获得内在利益;而后者则被社会无偿享用了.由于外溢利益具有改善经济运行环境的重大作用,最终使得经济增长速度加快,各国政府非常乐于代表社会补贴教育.这种经济学理论上的认识大大促进了各国政府制定有利于教育发展的国策,而本文最后一部分的国际比较说明,我国不仅需要从理论上认识教育的作用,更需要从政策上大力扶持我国已经大大落后于世界的教育事业.
