This study uses six censuses (1953,1964,1982,1990,2000,and 2010) at the county level since the foundation of the People’s Republic of China to examine the changes of population density pattern in mainland China over time.Based on the Gini coefficient,the change of disparity in population density followed a “U-shaped” trend,i.e.,decreasing during 1953–1982 and increasing during 1982–2010.The shrinking disparity in the pre-reform periods was largely attributable to various ill-conceived political movements,and the enlarging gap in population growth rates in the post-reform era reflected a natural outcome of urbanization,which will continue in the foreseeable future.In addition,this research employs a GIS-automated regionalization method,REDCAP,to uncover a natural demarcation line like the classic “Hu Line” that divides China into two regions of similar area sizes but a strong contrast in population.The results show that the regionalization-derived lines were largely consistent with the Hu Line over time.Therefore,the disparity between the high-density southeast and low-density northwest regions is likely due to differing physical environments that form a natural barrier.Any public policy to overcome this barrier at a large scale is destined to be a vain attempt. 展开更多

Numerous approaches have been developed to quantify forest structure modules.A variety has measured each as part of stand attributes.This study was carried out in managed mixed stands in northern Iran.The objective was to quantify stand structure and its variation before and after tree marking through the Gini index and structural triangle method.A full sampling inventory was taken in 2004 and 2014 at the beginning and end of a period,before and after tree marking operations in five stands.The results indicate that the Gini index was 39.5,62.2,43.0,82.0 and 74.0%forⅠ,Ⅱ,Ⅲ,ⅣandⅤstands respectively.Furthermore,approximate structural diameters were determined as a large category forⅠ,Ⅱ,ⅢandⅤstands while standⅡhad an intermediate-large class pre-tree marking to an intermediate-small class post-tree marking.The paired t-test results were not significant for tree numbers and growing stock changes for all species,and for beech,hornbeam,and velvet maple before and after tree harvesting in the whole stand.Therefore,the Gini index and the structural triangle method can be used for natural stand modeling,structural diversity designation,and for management practices in nature-oriented forestry strategies. 展开更多

Imbalanced data is one type of datasets that are frequently found in real-world applications, e.g., fraud detection and cancer diagnosis. For this type of datasets, improving the accuracy to identify their minority class is a critically important issue. Feature selection is one method to address this issue. An effective feature selection method can choose a subset of features that favor in the accurate determination of the minority class. A decision tree is a classifier that can be built up by using different splitting criteria. Its advantage is the ease of detecting which feature is used as a splitting node. Thus, it is possible to use a decision tree splitting criterion as a feature selection method. In this paper, an embedded feature selection method using our proposed weighted Gini index (WGI) is proposed. Its comparison results with Chi2, F-statistic and Gini index feature selection methods show that F-statistic and Chi2 reach the best performance when only a few features are selected. As the number of selected features increases, our proposed method has the highest probability of achieving the best performance. The area under a receiver operating characteristic curve (ROC AUC) and F-measure are used as evaluation criteria. Experimental results with two datasets show that ROC AUC performance can be high, even if only a few features are selected and used, and only changes slightly as more and more features are selected. However, the performance of Fmeasure achieves excellent performance only if 20% or more of features are chosen. The results are helpful for practitioners to select a proper feature selection method when facing a practical problem. 展开更多

Urban cultural space(UCS) has been of great social and economic value for sustainable development, and the existing researches about it mainly focus on some specific aspects, such as historical heritage or cultural service facility. However, UCS hasn’t been quantitatively assessed as an independent system with clear definition and comprehensive classification. Thus, we present a quantitative analysis based on the statistic of UCS provision in different categories between 44 sub-districts in Xi’an and find its inequalities. Xi’an urban land use data and population data of sub-district level are introduced in the analysis process with GIS,SPSS and MATLAB. Our results indicate that inequalities of UCS in Xi’an are mainly reflected in three aspects, including categories, geospatial and population. Among the four categories of UCS, historical heritage and cultural park account for higher percentage, while cultural service facility and religious space are lower. The inequalities in geospatial could be estimated from two indicators. The first indicator named cultural space rate ranges from 0 to 66.88%, while the other named distance between residential and cultural space varies from 100.47 m to 2004.75 m. The inequalities in population could be assessed by cultural space per capita and Gini coefficient. The results indicate that per capita ranges from 0 m~2 to 214.79 m~2. The Gini coefficient of Xi’an is 0.86, which means that the UCS distribution in population is extremely inequitable. Our studies would further the research on UCS and provide constructive suggestions in urban planning and policy formulation to ensure adequate UCS provision and improve its distributional order in Xi’an. 展开更多

According to the complex adaptive systems theory, tourist destinations may be regarded as complex adaptive systems formed by multiple adaptive agent interactions and composed of an agent system, tourist attraction subsystem, tourist service facility subsystem, and external environment system. This paper explores the spatial evolutionary progress of the Southern Anhui tourist area. The period 1979 to 1990 comprised the formation stage of spatial agglomerates, during which tourist attractions centering on Huangshan Scenic Area and Jiuhuashan Scenic Area were gradually exploited and formed scale agglomeration;tourism spatial structure began to show the characteristics of agglomeration development, and Gini indexes of the number of tourists and tourism revenue increased significantly from 0.26 to 0.29, and from 0.33 to 0.35, respectively. From 1991 to 2008, the system experienced a growth stage in which Huangshan Scenic Area and Jiuhuashan Scenic Area were further developed with improved tourist service facilities. Rapid development of Xidi-Hongcun Scenic Area and establishment of Fantawild Tourist Area promoted the formation of more spatial agglomerates with larger scales;Gini indexes of the number of tourists and tourism revenue presented fluctuating changes, reaching low points of 0.15 and 0.25 in 2000 and 0.12 and 0.22 in 2007, respectively. From 2009 to the present day, the system has remained in a blowout-development stage, during which non-linear interactions among agents are strengthened;various emerging development factors generate cultural tourism, vacation tourism, rural tourism and other new tourism products jointly with traditional development factors. New tourism products form a large number of new spatial agglomerates that are interconnected, accelerating the spatial flow of tourists and tourism revenue and reducing the differences in tourism development levels within the region;Gini indexes of the number of tourists and tourism revenue declined steadily from 0.17 and 0.23 in 2009 to 0.12 and 0.15 in 2 展开更多

The objective of this work is the study of social and economic inequality in the space of Central and Eastern Europe and its impact on economic growth. Our study includes a three-stage methodology:(1) application of a clustering method based on neural network (Self Organising Maps), to the series of panel data in order to divide countries into clusters, corresponding to the degree of economic and social inequality;(2) computing a composed index of economic and social inequality, using Principal Component Analysis and an extension of the method provided by OECD for computing composite indicators;(3) constructing an econometric model to establish the impact of social and economic inequality on economic growth and a VAR model to determine the causality between main determinants to growth and inequality as well as the response to shocks to the dynamics of the variables. The 24 Eastern and Central European countries have been grouped in five clusters, according to 11 attributes. In the results obtained, the third cluster comprises countries with the most equitable income distribution: Czech Republic, Croatia, Hungary, Slovak Republic, Slovenia. To the opposite side is the fifth cluster with the deepest inequality, including only one country, namely Georgia. The second and third steps of our methodology, were applied only for the extreme clusters namely, the clusters with the highest (C5) and lowest (C3) inequality respectively. 展开更多

Background:Health behavior is an action taken by a person to maintain, attain, or regain good health and to prevent illness. As such, health behavior reflects a person’s health beliefs and attracts many published papers in academics. However, who is the most influential author (MIA) remains unknown. Objective: The purpose of this study is to apply the algorithm of between centrality(BC) in social network analysis (SNA) to select the MIA on the topic of health behavior using the visual displays on Google Maps. Methods: We obtained 3,593 abstracts from Medline based on the keywords of (health [Title]) and (behavior [Title] or behaviour [Title]) on June 30, 2018. The author names, countries/areas, and author-defined keywords were recorded. The BCs were applied to (1) select the MIA using SNA;(2) display the countries/areas distributed for the 1st author in geography,(3) discover the author clusters dispersed on Google Maps, and (4) investigate the keywords dispersed for the cluster related to the MIA on a dashboard. Pajek software was performed to yield the BC for each entity (or say node). Results: We found that the MIA is Spring, Bonnie (US). All visual representations that are the form of a dashboard can be easily displayed on Google Maps. The most influential country and the keywords are the US and health behavior. Readers are suggested to manipulate them on their own on Google Maps. Conclusion: Social network analysis provides wide and deep insight into the relationships with the pattern of international author collaborations. If incorporated with Google Maps, the dashboard can release much more information regarding our interesting topics for us in academics. The research approach using the BC to identify the same author names can be applied to other bibliometric analyses in the future. 展开更多

Economic damage due to hurricane activities has been shown to impact income inequality in the coastal states of the United States. We consider 17 other natural hazards, in addition to hurricanes, that affected the entire United States for the period 1970–2013. Two fixed effects models were developed to quantify the relationship between income inequality and economic and demographic variables, including crop and property losses from natural hazard-induced disasters. These models include state-byyear and region-by-year fixed effects models. Our findings show that the damages from all natural hazards impact income distribution across the United States, not only in hurricane-affected areas, but also in non-hurricane states.The results of our study have important implications for the insurance industry and government policymakers. 展开更多

Background: The literature on the socioeconomic determinants of oral health inequalities is rather limited. Since oral health is an integral part of general health, the investigation of oral and general health inequalities becomes an important research topic. The recent economic crisis has aggravated the level of general and oral health in Greece and evidence on inequalities is interesting for policy guidelines. Objective: The purpose of the present study is to measure the magnitude of self reported oral health inequalities in relation to certain demographic and socio-economic indicators such as gender, age, education and income status. Methods: We launched a cross-sectional survey across urban and rural population in Greece and we selected a random sample of 1500 individuals consisting of three age groups: 15 - 18 years, 35 - 45 years, and 65 to 74 years old. Self-reported general and oral health were both recorded and analyzed by means of an ordinal scale ranging from 0 = worse health to 100 = perfect health. Likert-type of scale questions were further used to capture self assessments of oral health. Dental Inequalities were assessed with reference to the following socio-economic variables: age, education, and income levels. Results: Statistically significant oral health inequalities were identified among the socio-economic groups in Greece. Lower levels of oral health were associated with those confronting financial difficulties, the aged and the less educated. The Gini Coefficient for Oral Health Goral = 0.344 (s.d. = 0.0033) was higher in comparison to general health Ggeneral = 0.289 (s.d. = 0.0016) indicating the need for public health intervention in the area of oral health. Conclusions: The paper demonstrates the significance of socioeconomic inequalities in oral health in Greece. 展开更多
