Hazard assessment of landslide disaster using information value method and analytical hierarchy process in highly tectonic Chamba region in bosom of Himalaya

引用

Journal of Mountain Science 2018年第4期15卷 808-824页

作者： Kanwarpreet SINGH Virender KUMAR Civil Engineering Department National Institute of Technology

The present study is focused on a comparative evaluation of landslide disaster using analytical hierarchy process and information value method for hazard assessment in highly tectonic Chamba region in bosom of Himalaya. During study, the information about the causative factors was generated and the landslide hazard zonation maps were delineated using information value Method(IV) and Analytical Hierarchy Process(AHP) using Arc GIS(ESRI). For this purpose, the study area was selected in a part of Ravi river catchment along one of the landslide prone Chamba to Bharmour road corridor of National Highway(NH^(-1)54 A) in Himachal Pradesh, India. A numeral landslide triggering geoenvironmental factors i.e. slope, aspect, relative relief, soil, curvature, land use and land cover(LULC), lithology, drainage density, and lineament density were selected for landslide hazard mapping based on landslide inventory. Landslide hazard zonation map was categorized namely "very high hazard, high hazard, medium hazard, low hazard, and very low hazard". The results from these two methods were validated using Area Under Curve(AUC) plots. It is found that hazard zonation map prepared using information value method and analytical hierarchy process methods possess the prediction rate of 78.87% and 75.42%, respectively. Hence, landslide hazardzonation map obtained using information value method is proposed to be more useful for the study area. These final hazard zonation maps can be used by various stakeholders like engineers and administrators for proper maintenance and smooth traffic flow between Chamba and Bharmour cities, which is the only route connecting these tourist places.

Content sensitivity based access control framework for Hadoop

Digital Communications and Networks 2017年第4期3卷 213-225页

作者： Ashwin Kumar T.K. Hong Liu Johnson P. Thomas Xiaofeh Hou Department of Computer Science Oklahoma State University Stillwater OK USA

Big data technologies have seen tremendous growth in recent years. They are widely used in both industry and academia. In spite of such exponential growth, these technologies lack adequate measures to protect data from misnse/abuse. Corporations that collect data from multiple sources are at risk of liabilities due to the exposure of sensitive information. In the current implementation of Hadoop, only file-level access control is feasible. Providing users with the ability to access data based on the attlibutes in a dataset or the user＇s role is complicated because of the sheer volume and multiple formats （structured, unstructured and semi-structured） of data. In this paper, we propose an access control framework, which enforces access control policies dynamically based on the sensitivity of the data. This framework enforces access control policies by harnessing the data context, usage patterns and informat/on sensitivity. information sensitivity changes over time with the addition and removal of datasets, which can lead to modifications in access control decisions. The proposed framework accommodates these changes. The proposed framework is automated to a large extent as the data itself determines the sensitivity with minimal user intervention. Our experimental results show that the proposed framework is capable of enforcing access control policies on non-multimedia datasets with minimal overhead.

Research on the Platform-Based Retail Business Model Innovation

China Finance and Economic Review 2020年第1期9卷 108-128页

作者： Binbin Zheng Business School Putian UniversityFujian

With the rise of the platform economy,the retail industry is facing great pressure to shift from a traditional growth model to a platform-based growth *** one-sided market theory applicable to the traditional business models cannot adequately explain business model innovation in the platform-based growth *** on a systematic analysis of the platform economy theory,business model innovation theory,value co-creation theory,and dynamic capability theory and in light of the characteristics of the retail industry,this paper proposes that to achieve platform-based growth,retail business model innovation should be focused on changing the ways to create customer value and capture enterprise value and leveraging modern information systems to achieve value co-creation during the transformation of key business processes ranging from procurement and sales to *** addition,enterprises must get rid of the mindset of making profi ts from the difference between buying and selling prices and should instead explore new sources of revenue through linking dividend and information *** platform operators,retail enterprises need to develop dynamic capabilities through the interaction of heterogeneous resources of various platform participants and especially the introduction of social resources,so as to propel innovation in retail business models and ultimately the transformation from traditional growth to platform-based growth.

在销售系统中存在着典型的信息不对称：委托人(公司)对代理人(销售人员)的努力程度具有非对称信息，但可以观测到代理人的销售业绩并据此给予代理人相应的薪酬。在假设市场最终需求对努力水平敏感，且某代理人努力水平提高可以在开拓市场的同时吸引对方顾客的条件下，建立了信息对称和非对称情况下的销售系统中具有多代理人且代理人间存在竞争的委托代理模型。分析了该模型，得到信息对称情况下代理人薪酬与他们之间的竞争程度无关；而信息非对称时，虽然委托人由于缺乏信息而受到了损失，但利用代理人之间的竞争可以降低委托人的损失，且代理人的努力程度随着竞争程度提高也不得不提高等结论。

Research on Personal Credit Evaluation Based on Mobile Telecommunications Data

Journal of Data Analysis and information Processing 2021年第3期9卷 151-161页

作者： Shaoyong Hong Yan Zhang Chun Yang Guangzhou Huashang College Guangzhou China Guangdong Teachers College of Foreign Language and Arts Guangzhou China Guangdong Foreign Trade Vocational Technology School Guangzhou China

With the rapid development of big data technology, the personal credit evaluation industry has entered a new stage. Among them, the evaluation of personal credit based on mobile telecommunications data is one of the hotspots of current research. However, due to the complexity and diversity of personal credit evaluation variables, in order to reduce the complexity of the model and improve the prediction accuracy of the model, we need to reduce the dimension of the input variables. According to the data provided by a mobile telecommunications operator, this paper divides the data into a training sets and verification sets. We perform correlation analysis on each indicator of the data in the training set, and calculate the corresponding IV value based on the WOE value of the selected index, then binning data with SPSS Modeler. The selected variables were modeled using a logistic regression algorithm. In order to make the regression results more practical, we extract the scoring rules according to the results of logistic regression, convert them into the form of score cards, and finally verify the validity of the model.

思考档案数据共享的价值问题，有助于探寻档案行业数据化转型的内在逻辑与价值意蕴。以档案双元价值论为指导，发现档案数据是工具价值与信息价值的双元价值结合体，共享是档案数据价值最大化实现的必然选择。对档案数据价值的认识偏颇，成为实践中档案数据不愿共享、不敢共享与不能共享的思想根源。遵循“双元并重”的价值理念，档案数据共享既要重视工具价值的“求真”，确保共享档案数据的真实性；也要关注信息价值的“促用”，提升档案数据共享的实效性。
