Risk Evaluation of Real Estate Based on AHM and Fuzzy Set

TL;DR: A new method based on the AHM (Analytic hierarchical model) and the fuzzy comprehensive evaluation was proposed and engineering practice and comparison showed the rationality of the method.
Abstract: In order to find an effective method to deal with the uncertainty of the risk evaluation of real estate investment, a new method based on the AHM (Analytic hierarchical model) and the fuzzy comprehensive evaluation was proposed. After the establishment of the evaluation system, the AHM was employed to determine the weight of every index, and the value of the risk was obtained by using the fuzzy set. Engineering practice and comparison with other existing methods showed the rationality of the method. This study provides a promising approach for the risk evaluation of real estate investment and has significance in theory and practice for the risk management of investment.

TL;DR: In this article, the authors apply the integrated, multilevel framework developed in the West to explain variation in the risk of household burglary within the city of Tianjin, China The analytic framework consists of three sets of determinants: household variables, neighbourhood structural factors, and neighbourhood social control processes.
Abstract: This study applies the integrated, multilevel framework developed in the West to explain variation in the risk of household burglary within the city of Tianjin, China The analytic framework consists of three sets of determinants: household variables, neighbourhood structural factors, and neighbourhood social control processes The selection of variables is guided by routine activities/lifestyle theories and the social disorganization perspective, adapted to refl ect features of urban China The results of multilevel regression modeling reveal that indicators of target attractiveness (household income) and guardianship (length of residence and ‘ somebody home ’ ) exhibit the predicted effects on the risk of household burglary Similarly, the effects of two of the neighbourhood process variables — collective effi cacy and public control — conform to theoretical expectations and fi ndings in Western research The results for the neighbourhood structural factors are inconsistent with those widely reported in the West These analyses demonstrate the applicability of elements of Western criminological theory to contemporary urban China but also reveal important differences in the ecological dynamics of crime across contexts

TL;DR: In this article, the authors discuss the Chinese concern with bicycle theft and explore the social and legal aspects of bicycle-theft victimization in China, drawing upon the lifestyle-exposure and routine-activities perspectives, they specify a number of important household-and neighborhood-level variables as indicators of target attractiveness, guardianship, and exposure to potential offenders.
Abstract: China has been characterized as a “bicycle nation.” Since the economic reform was initiated in the early 1980s, bicycles have become a major target of criminal activities because of their availability, utility, and monetary value, and because of the difficulty of securing them. The present study discusses the Chinese concern with bicycle theft and explores the social and legal aspects of bicycle-theft victimization in China. Drawing upon the lifestyle-exposure and routine-activities perspectives, the present study specifies a number of important household- and neighborhood-level variables as indicators of target attractiveness, guardianship, and exposure to potential offenders to explore the risk of bicycle theft in urban China. Using data collected from a recent survey in the city of Tianjin, the study conducts multilevel analyses of the risk and protective factors for bicycle-theft victimization. The data show that house type (row houses) and number of adult household members are significant protective ...
