naturally all activities are along with risk and uncertainties. project risk has the concept more than the financial concept. in project management, risks are events that can occur during the project implementation and has negative effects on project completion and meeting goals. identification, analysis, prioritizing and having plan for dealing with these events are playing an important role i...

Background: In sub-Saharan Africa (SSA), the trend in the number of patients admitted for maintenance hemodialysis is on the rise. The identification of risk factors for chronic kidney disease (CKD) ensures adequate primary and secondary preventive measures geared at reducing the burden of CKD in low-resource settings. A family history of CKD is an established risk factor for C...

Background and Purpose—Women face a higher mortality after stroke and have different risk factors than men. Despite educational campaigns, women continue to underestimate their own risk for stroke. We present a theoretical model to understand risk perception in high-risk women. Methods—Eight hundred five women, ages 50 to 70 years, were selected from the University of Connecticut Cardiology Cen...

BACKGROUND Our objective was to develop a model for measuring re-identification risk that more closely mimics the behaviour of an adversary by accounting for repeated attempts at matching and verification of matches, and apply it to evaluate the risk of re-identification for Canada's post-marketing adverse drug event database (ADE).Re-identification is only demonstrably plausible for deaths in ...

We analyze heart transplant data from the United Network for Organ Sharing (UNOS) program with the aim of developing accurate risk prediction models for mortality within 1 year of heart transplant using data mining techniques. The data used in this study is de-identified and consists of 50 predictor attributes, and 1-year posttranplant survial outcome for patients who underwent heart transplant...
