Before entering into any investment, the risk of that venture must be identified and quantified. The Handbook of Risk provides in-depth coverage of risk from every possible angle and illuminates the subject by covering the quantitative and and behavioral issues faced by investment professionals on a day-to-day basis. This valuable reference offers a prescriptive and descriptive treatment of risk management for those looking to control, contain, and minimize the risk of their investments.
The risk management processes described in this book had their genesis well over 20 years ago when I accepted a position at the University of Southampton. There I met and worked with Dr Chris Chapman, already an acknowledged expert in project risk, with an established relationship with BP and an extensive client base in Canada. Chris involved me in his consulting activities in North America, primarily associated with quantitative risk analyses of large projects in the hydroelectric and the oil and gas industries....
This book is a compilation of 29 chapters focused on: pesticides and food production, environmental effects of pesticides, and pesticides mobility, transport and fate. The first book section addresses the benefits of the pest control for crop protection and food supply increasing, and the associated risks of food contamination.
Recent experience illustrates this point. Consider the fact
that the Fed cut interest rates sharply in response to two of the
most serious financial crises in recent years: the October 1987
stock market break and the turmoil following the Russian
default in 1998. Arguably, in retrospect, interest rate policy
remained too easy for too long in both cases.
Convertible bonds can be difficult to value, given their hybrid nature of containing elements of both debt and equity.
Further complications arise due to the frequent presence of additional options such as callability and puttability,
and contractual complexities such as trigger prices and “soft call” provisions, in which the ability of the issuing firm
to exercise its option to call is dependent upon the history of its stock price.
Association rules represent a promising technique to find
hidden patterns in a medical data set. The main issue about
mining association rules in a medical data set is the large
number of rules that are discovered, most of which are irrelevant.
Such number of rules makes search slow and interpretation
by the domain expert difficult. In this work, search
constraints are introduced to find only medically significant
association rules and make search more efficient.
Control measures for pneumonia (Table 125-2) are aimed at the remediation of risk factors in general patient care (e.g., minimizing aspirationprone supine positioning) and at meticulous aseptic care of respirator equipment (e.g., disinfecting or sterilizing all inline reusable components such as nebulizers, replacing tubing circuits at intervals of 48 h—rather than more frequently—to lessen the number of breaks in the system, and teaching aseptic technique for suctioning).
Urinary Tract Infections Urinary tract infections (UTIs) account for as many as 40–45% of nosocomial infections; up to 3% of bacteriuric patients develop bacteremia. Although UTIs contribute only 10–15% to prolongation of hospital stay and to extra costs, these infections are important reservoirs and sources for spread of antibiotic-resistant bacteria in hospitals. Almost all nosocomial UTIs are associated with preceding instrumentation or indwelling bladder catheters, which create a 3–10% risk of infection each day.
Patients colonized with C. difficile were initially thought to be at high risk for CDAD. However, four prospective studies have shown that colonized patients actually have a decreased risk of subsequent CDAD. At least three events are proposed as essential for the development of CDAD (Fig. 123-2). Exposure to antimicrobial agents is the first event and establishes susceptibility to C. difficile infection. The second event is exposure to toxigenic C. difficile.
Recurrent CDAD Overall, ~15–30% of patients experience recurrences of CDAD, either as relapses caused by the original organism or as reinfections following treatment (Table 123-2). Recurrence rates are higher among patients ≥65 years old and among patients who remain in the hospital after the initial episode of CDAD. Patients who have a first recurrence of CDAD have a high rate of second recurrence (33–65%). In the first recurrence, re-treatment with metronidazole is comparable to treatment with vancomycin.
The idea of analyzing your business processes and determining what are the risks that threaten those processes, and choosing cost effective countermeasures to minimize the risks and the associated losses.
Low-carbohydrate diets have been advocated for weight loss and to prevent obesity,
but the long-term safety of these diets has not been determined.
We evaluated data on 82,802 women in the Nurses’ Health Study who had completed
a validated food-frequency questionnaire. Data from the questionnaire were
used to calculate a low-carbohydrate-diet score, which was based on the percentage
of energy as carbohydrate, fat, and protein (a higher score reflects a higher intake
of fat and protein and a lower intake of carbohydrate).
Most of the epidemiological studies which compared breast
cancer risk of active smokers to women who were not
smokers (regardless of their passive smoke exposure) have
found no association of smoking and breast cancer risk. But
several studies found that women who smoked had a
decreased breast cancer risk. It is not uncommon for
epidemiological studies to come to different assessments of
health risk, especially when, as in these studies, the associated
risk is not large.
.The research described in this report was prepared for the Office of the Secretary of Defense (OSD) and conducted in the RAND National Defense Research Institute, a federally funded research and development center sponsored by the OSD, the Joint Staff, the Unified Combatant Commands, the Department of the Navy, the Marine Corps, the defense agencies, and the defense Intelligence Community under Contract W74V8H-06-C-0002.
Mutations in the tumor suppressor breast cancer susceptibility gene 1
(BRCA1), an important player in the DNA damage response, apoptosis,
cell cycle regulation and transcription, confer a significantly elevated life-time risk for breast and ovarian cancer.
