Developing An IT Risk Assessment Framework
In today’s business environment, almost all information is captured and stored in electronic form. This digital storage of data in a networked environment provides far greater access to information than ever before. But unfortunately, this also exposes the organization to a variety of new threats that can have impact on the confidentiality, integrity, and availability of information. Organizations need a way to understand their information risks and to create new strategies for addressing those risks. A systematic approach to assessing information security risks and developing an appropriate protection strategy is a major component of an effective information security and risk management program. This paper outlines an Analytic Hierarchy Process based approach for analyzing risk factors and sub factors and ascertaining the major areas of security elements where an organization should focus on
Risk Management For Health Information Security And Privacy
The challenge of securing large amounts of electronic medical records stored in a variety of forms and in many locations, while still making it available to authorized users, is huge. Pressure to maintain privacy and protection of personal information is a strong motivating force in the development of security policies. It is essential for health care organizations to analyze, assess and ensure security policies to meet these challenges and to develop the necessary policies to ensure the security of medical information

A neural network driven fuzzy system approach to decision making
It is necessary to model and manage uncertainties efficiently and effectively in solving decision-making problems. Fuzzy reasoning and logic offers a natural means of handling uncertainty. This paper discus.\u27ses the development of an architecture that utilizes the advantages of fuzzy logic and neural networks that can be used in decision-making. The present paper outlines the reasons that motivate development of models that integrate fuzzy logic and neural networks. This discussion is followed by a brief overview of fuzzy logic and its concepts that are essential in understanding the application presented in the paper. The paper then describes the classification procedure used by the model, which is followed by its application to the decision making problem in construction modularization
Technologies To Improve The Decision-Making Process Of Real Estate Appraisers: XML, Intelligent Agents, Avms, And Web Services
Pressure to expedite mortgage originations has prompted the need to accelerate the appraisal process for residential real estate. The appraisal aspect of a mortgage origination is one area where decision support can play a major role in redefining the process. This study presents propositions that incorporate new technologies into the decision-making process of a residential real estate appraiser. The four propositions deal with intelligent agents, XML, automated valuation models (AVMs), and web services. Intelligent agents have the ability to redefine how appraisal firms create, maintain, and update their databases. XML offers enhanced data handling capabilities, while automated valuation models offer the ability to drastically reduce the time required to render an estimate of value. These two technologies can be combined with web services to make the real estate appraisal application available anywhere and anytime of the day

A neural network model for decision making With application in construction management
In this paper, an innovative approach is presented to decision making using self-organizing multi-layered neural networks. The model helps make a decision whether to use a conventional stick-built method or to use some degree of modularization when building an industrial process plant - a problem considered very important in construction management because of its economic impact. The objective of this paper is to show that both expert system and neural network approaches can be useful for decision making problems. However, in some situations a neural network approach can outperform the expert system approach. A brief overview of prior approach to modular construction decision making is provided in this paper and the reasons for using a neural network approach are also discussed. The architecture, knowledge representation, and training procedure for the neural network paradigms used are described. The performance of the trained neural network system and its comparison with the recommendations provided by human experts and the expert system are also presented
Enhancing Knowledge Management With XML
Knowledge Management involves gathering, categorizing, storing and sharing of knowledge. There are several available tools that can be used to build a knowledge management infrastruc-ture to achieve its goals. This paper discusses issues involved in designing an information Portal using XML-based tools. As compared to traditional HTML-based portals, use of XML offers several benefits - it provides a great way of efficiently aggregating, classifying, and presenting both structured and unstructured content over the Internet or similar networks
Effect of compost addition on arsenic uptake, morphological and physiological attributes of maize plants grown in contrasting soils
Contamination of soils with arsenic (As) represents a global environmental and health issue considering the entrance of toxic As in the human food chain. Although partially understood, addition of compost for the remediation of As-contaminated soils may result in distinct effects on plant growth and physiological attributes depending on compost-mediated potential mobility/sequestration of As in soils. This study explores the role of compost addition (C; 0, 1 and 2.5%) on morphological and gas exchange attributes and photosynthetic pigments (chlorophyll contents) of maize plants under As stress (0, 40, 80, 120 mg kg− 1), as well as soil As immobilization/mobilization in a pot experiment, using two contrasting soils. Results revealed that, in Narwala (sandy loam) soil, the addition of compost decreased shoot As concentration of maize plants (p < 0.05; 4.01–13.7 mg kg− 1 dry weight (DW)), notably at C2.5 treatment, with significant improvement in shoot dry biomass, gas exchange attributes and chlorophyll (a and b) contents, i.e., 1.33–1.82, 1.20–2.65 and 1.34–1.66 times higher, respectively, over C0 at all As levels. Contrastingly, in Shahkot (clay loam) soil, C2.5 treatment increased shoot As concentration (p < 0.05; 7.02–17.3 mg kg− 1 DW), and as such reduced the shoot dry biomass, gas exchange attributes and chlorophyll contents, compared to the control – rather C1 treatment was more effective and exhibited positive effect than C2.5. Considerably, at C2.5 treatment, phosphate extractable (bioavailable) soil As concentration was also found to be greater in the (post-experiment) Shahkot soil than that of Narwala soil (0.40–3.82 vs. 0.19–1.51 mg kg− 1, respectively). This study advanced our understanding to resolve the complex compost-As interactions in As-contaminated soils, which are imperative to understand for developing the effective and soil-specific remediation strategies

Electronic Health Records: Challenges and Opportunities
During the last three decades, healthcare expenditure in the U.S. has substantially increased. If this pace of increase is not controlled, it will lead to disastrous results for the healthcare system. An effective use of health information technology would not only improve the quality of healthcare but help reduce healthcare costs considerably. However, risks of privacy and security of patient electronic health records are great. It is recommended that healthcare organizations use IT management best practices, follow proper risk assessment and management guidelines, and keep up with latest technological advances to ensure the privacy and security of patient data
