...Original Contributions Data Mining Applications in Healthcare Hian Chye Koh and Gerald Tan A B S T R A C T Data mining has been used intensively and extensively by many organizations. In healthcare, data mining is becoming increasingly popular, if not increasingly essential. Data mining applications can greatly benefit all parties involved in the healthcare industry. For example, data mining can help healthcare insurers detect fraud and abuse, healthcare organizations make customer relationship management decisions, physicians identify effective treatments and best practices, and patients receive better and more affordable healthcare services. The huge amounts of data generated by healthcare transactions are too complex and voluminous to be processed and analyzed by traditional methods. Data mining provides the methodology and technology to transform these mounds of data into useful information for decision making. This article explores data mining applications in healthcare. In particular, it discusses data mining and its applications within healthcare in major areas such as the evaluation of treatment effectiveness, management of healthcare, customer relationship management, and the detection of fraud and abuse. It also gives an illustrative example of a healthcare data mining application involving the identification of risk factors associated with the onset of diabetes. Finally, the article highlights the limitations of data mining and discusses some future directions....

... MINING INDUSTRY - OVERVIEW AND RISKS FACTORS Definition of the Industry The mining industry encompasses a wide range of companies involved in different supply chain positions that represent exploration, development, extraction, processing, refining and sale of minerals and coal. With respect to the diverse set of business factors that affect the mining process, the business risk rating for the mining industry would be best qualified in terms of a credit rating of BBB (low). The justification for this rating follows: a) Higher than average profitability of the industry – related to the need to provide adequate returns on large capital investments b) Threat of competitors is about on the same level as other industries – based on multiple suppliers and buyers and the prevalence of homogenous products (nonbranded) c) Inherent volatility in earnings and underlying cash flows – due to volatile pricing of commodity products and responsiveness to economic cycles d) Above average and increasing prospect of industry regulation e) Above average and uncertain political risk – industry players have to pursue operations where mineral resources are found and in many cases this would include politically unstable regions f) Below average technology risks – due to the basic nature of the materials produced and licensing production technologies and methods among players in the industry 2 The BBB rating is applicable only to industry players...

Data mining software is one of a number of analytical tools for analyzing data. It allows users to analyze data from many different dimensions or angles, categorize it, and summarize the relationships identified. Technically, data mining is the process of finding correlations or patterns among dozens of fields in large relational databases. CRM: In today’s competitive scenario in corporate world, “Customer Retention” strategy in Customer Relationship Management (CRM) is an increasingly pressed issue.

Nonetheless the failure to manage this enormous amount of data, and to swiftly acquire the information that is relevant to any particular question, as the volume of information rises, demonstrates to be a distraction and a liability, rather than an asset. This paradox energies the need for increasingly powerful and flexible data management systems. To achieve efficiency and a great level of productivity out of large and complex datasets, operators need have tools that streamline the tasks of managing the data and extracting valuable information...

...Barrack Gold Corporation Introduction The following essay focuses on the mining conglomerate Barrick Gold Corporation. Barrick owns gold and copper mines across Australia, Africa, and the Americas and these geographical locations provide the focus of the essay’s Macroenviromental analysis. The gold is sold to various gold bullion dealers at market prices whereas copper is sold to copper product manufacturers and copper traders in Europe, North America, South America and Asia (BarrickResponsibilty, 2013). Barrick’s Macroenviroment According to Kotler et al. (2011) a company and all of the other actors operate in a larger macroenviroment of forces that shape opportunities and pose threats to a company such as Barrick. Jobber and Ellis-Chadwick (2013) further imply that it is these actors and forces that affect the mining company’s capability to operate effectively in providing products and services to its customers. Its external environment is characterized by elements that do not have an immediate impact on its performance albeit their impact being felt over the long term. There are those that can influence the company marketing activities without management being able to control them hence the need to continuously monitor them or risk going out of business (Wilson, 2006). The framework that best discusses these elements is the PESTLE Analysis as it provides the strategic planning and environmental analysis that can be useful for Barrick to improve performance and ensure its long...

...Canadian mining- Impact of cost inflation and volatility and the road ahead Introduction With a 9.8% share of Canada’s GDP, the mining sector is critical to the future of the Canadian economy (Deloitte Report). Unfortunately, rising cost inflation, unprecedented volatility in commodity and energy prices and a strong Canadian dollar have negatively impacted the performance of this sector over the last year. This report seeks to uncover the drivers behind cost inflation and evaluate the hedging strategies utilized by Canadian companies to mitigate volatility through a case study of Barrick Gold. We will also examine the impact of tightening margins on the capital expenditure decisions of this company. Part 1: Cost Inflation Cost inflation in the mining industry has been driven by increases in both Operational expenses and Capital expenditures. Operational expenses have been driven by three factors 1) Wage Increases 2) Energy Costs and 3) Supply cost increases. Wages in this industry have increased dramatically over the past 10 years and the Canadian mining industry now boasts the highest wages of all industrial sectors in Canada. The average weekly pay for a mining worker in 2011 was $1,436, which surpassed the earnings of workers in forestry, manufacturing, finance and construction by 47%, 46%, 35% and 32% respectively (DELOITTE REPORT) Source: Mining Association of Canada – 2012 Facts & Figures Report http://www.mining.ca/www/media_lib/MAC_Documents/P...

This report includes a brief overview of the industry followed by an evaluation of the Mining industry’s value chain; including an environmental analysis of a mining company, as well as an evaluation of the industry’s corporate social responsibility, corporate social responsiveness and finally the corporate social performance. The Mining Industry is one of the World’s largest industries. The ‘idea’ of mining dates back to the beginning stage of civilization. Some examples of early mining can be found in Egypt, Europe and the Philippines. As of now, top mining countries are South Africa, Russia, Australia, Ukraine and Guinea. This industry faces constant technology advancement, consequently it is an expensive investment, with large profit. The Mining Industry can be controversial when looked through an ethical lens. This Industry is analysed through four perspectives. * The utilitarianism perspective, an act is morally right if the outcome benefits the greatest amount of people; * The rights perspective, basically, important entitlements that should be respected and protected in every action; * The justice perspective, fair treatment of individuals in a situation where everyone is involved and gets what they deserve to; * The virtue perspective, morally...
