Where there is a significant actuarial basis for decision making (e.g., the occurrence of fires in single-family dwellings), there is little incentive for formal riskmanagement. Formal risk assessments are most useful in those cases where the value of the structure is high, many people may be affected, the societal perception of risk is high, consequences of a mishap would be severe, and the actuarial uncertainty is large. For these cases, there is little opportunity to obtain the necessary experiential data to make informed decisions, and the consequences in terms of money, lives, and societal confidence are severe enough to warrant a formal risk assessment. Other important factors include the symbolic value of the structure and vulnerability to single point failures. It is unlikely that formal riskmanagement and assessment practices will or should replace the proven institutions of building codes and engineering practices. Nevertheless, formal risk assessment can provide valuable insights into the hazards threatening high-value and high-risk (perceived or actual) buildings and structures, which can in turn be translated into improved public health, safety, and security. The key is to choose and apply the right assessment tool to match the structure in question. Design-for-reliability concepts can be applied to buildings, bridges, transportation sys- tems, dams, and other structures. The use of these concepts could have the dual benefits of lowering life-cycle costs by reducing the necessity for maintenance and repair and of enhancing the saiiety and security of the structure's users.

In competitive electricity markets, the vertically integrated utilities that were responsible for ensuring system reliability in their own service territories, or groups of territories, often cease to exist. Typically, the burden falls to an independent system operator (ISO) to insure that enough ancillary services (AS) are available for safe, stable, and reliable operation of the grid, typically defined, in part, as compliance with officially approved engineering specifications for minimum levels of AS. In order to characterize the behavior of market participants (generators, retailers, and an ISO) in a competitive electricity market with reliability requirements, we model a spot market for electricity and futures markets for both electricity and AS. By assuming that each participant seeks to maximize its expected utility of wealth and that all markets clear, we solve for the optional quantities of electricity and AS traded in each market by all participants, as well as the corresponding market-clearing prices. We show that future prices for both electricity and AS depend on expectations of the spot price, statistical aspects of system demand, and production cost parameters. More important, our model captures the fact that electricity and AS are substitute products for the generators, implying that anticipated changes in the spot market will affect the equilibrium futures positions of both electricity and AS. We apply our model to the California electricity and AS markets to test its viability.
This chapter of "Principles of School Business Management" presents an overview of riskmanagement for school districts. The chapter first discusses four fundamental elements of riskmanagement: (1) identifying and measuring risks; (2) reducing or eliminating risks; (3) transferring unassumable risks; and (4) assuming remaining risks. The chapter…
We present a simple, but powerful framework for software riskmanagement. The framework synthe- sizes, refines, and extends current approaches to manag- ing software risks. We illustrate its usefulness through an empirical analysis of two software development episodes involving high risks. The framework can be used as an analytical device to evaluate and improve riskmanage- ment approaches and as
Every plan contains risk. To proceed without planning some means of managing that risk is to court failure. The basic logic of risk is explained. It consists in identifying a threshold where some corrective action is necessary, the probability of exceeding that threshold, and the attendant cost should the undesired outcome occur. This is the probable cost of failure. Various risk categories in dentistry are identified, including lack of liquidity; poor quality; equipment or procedure failures; employee slips; competitive environments; new regulations; unreliable suppliers, partners, and patients; and threats to one's reputation. It is prudent to make investments in riskmanagement to the extent that the cost of managing the risk is less than the probable loss due to risk failure and when riskmanagement strategies can be matched to type of risk. Four riskmanagement strategies are discussed: insurance, reducing the probability of failure, reducing the costs of failure, and learning. A riskmanagement accounting of the financial meltdown of October 2008 is provided. PMID:21314051
Medical devices are required to be safe and effective before they are commercially marketed. However, there have been reports of adverse events, even deaths, due to unforeseen design efforts. How can biomedical engineers minimize potential hazards to users and operators? Riskmanagement is an essential engineering skill that all biomedical engineers should understand and use aggressively. Riskmanagement is the
A “ high level” , deductive-reasoning-based (“ holistic” ), approach is aimed at the direct analysis of the behavior of a system as a whole, rather than with an attempt to understand the system's behavior by conducting first a “ low level” , inductive-reasoning-based, analysis of the behavior and the contributions of the system's elements. The holistic view on treatment is widely accepted in medical practice, and “ holistic health” concept upholds that all the aspects of people's needs (psychological, physical or social), should be seen as a whole, and that a disease is caused by the combined effect of physical, emotional, spiritual, social and environmental imbalances. Holistic reasoning is applied in our analysis to model the behavior of engineering products (“ species” ) subjected to various economic, marketing, and reliability “ health” factors. Vehicular products (cars, aircraft, boats, etc.), e.g., might be still robust enough, but could be out-of-date, or functionally obsolete, or their further use might be viewed as unjustifiably expensive. High-level-performance functions (HLPF) are the essential feature of the approach. HLPFs are, in effect, “ signatures” of the “ species” of interest. The HLPFs describe, in a “ holistic” , and certainly in a probabilistic, way, numerous complex multi-dependable relations among the representatives of the “ species” under consideration. ; umerous inter-related “ stresses” , both actual (“ physical” ) and nonphysical, which affect the probabilistic predictions are inherently being taken into account by the HLPFs. There is no need, and might even be counter-productive, to conduct tedious, time- and labor-consuming experimentations and to invest significant amount of time and resources to accumulate “ representative statistics” to predict - he governing probabilistic characteristics of the system behavior, such as, e.g., life expectancy of a particular type of products. “ Species” of military aircraft, commercial aircraft and private cars have been chosen in our analysis as illustrations of the fruitfulness of the “ holistic” approach. The obtained data show that both commercial “ species” exhibit similar “ survival dynamics” in compare with those of the military species of aircraft: lifetime distributions were found to be Weibull distributions for all “ species” however for commercial vehicles, the shape parameters were a little higher than 2, and scale parameters were 19.8 years (aircraft) and 21.7 (cars) whereas for military aircraft, the shape parameters were much higher and the mean time to failure much longer. The difference between the lifetime characteristics of the “ species” can be attributed to the differences in the social, operational, economic and safety-and-reliability requirements and constraints. The obtained information can be used to make tentative predictions for the most likely trends in the given field of vehicular technology. The following major conclusions can be drawn from our analysis: 1) The suggested concept based on the use of HLPFs reflects the current state and the general perceptions in the given field of engineering, including aerospace technologies, and allows for all the inherent and induced factors to be taken into account: any type of failures, usage profiles, economic factors, environmental conditions, etc. The concept requires only very general input data for the entire population. There is no need for the less available information about individual articles. 2) Failure modes are not restricted to the physical type of failures and include economic, cultural or social effects. All possible causes, which might lead to making a decision to terminate the use of a particular type
The intention of this report is to bring a developing and extremely useful statistical methodology to greater attention within the Safety, Reliability, and Quality Assurance Office of the NASA Johnson Space Center. The statistical methods in this exposition are found under the heading of attributable risk. Recently the Safety, Reliability, and Quality Assurance Office at the Johnson Space Center has supported efforts to introduce methods of medical research statistics dealing with the survivability of people to bear on the problems of aerospace that deal with the reliability of component hardware used in the NASA space program. This report, which describes several study designs for which attributable risk is used, is in concert with the latter goals. The report identifies areas of active research in attributable risk while briefly describing much of what has been developed in the theory of attributable risk. The report, which largely is a report on a report, attempts to recast the medical setting and language commonly found in descriptions of attributable risk into the setting and language of the space program and its component hardware.
Abstract?isk assessment is an essential process of every software riskmanagement plan. Several risk assessment techniques are based on the subjective judgement of domain experts. Subjective risk assessment techniques are human intensive and error-prone. Risk assessment should be based on product attributes that we can quantitatively measure using product metrics.

The risk to the development of program reliability is derived from the use of a new language and from the potential use of new storage management techniques. With Ada and associated support software, there is a lack of established guidelines and procedures, drawn from experience and common usage, which assume reliable behavior. The risk is identified and clarified. In order to provide a framework for future consideration of dynamic storage management on Ada, a description of the relevant aspects of the language is presented in two sections: Program data sources, and declaration and allocation in Ada. Storage-management characteristics of the Ada language and storage-management characteristics of Ada implementations are differentiated. Terms that are used are defined in a narrow and precise sense. The storage-management implications of the Ada language are described. The storage-management options available to the Ada implementor and the implications of the implementor's choice for the Ada programmer are also described.
Leadership is key to success. Phased-approach for implementation of riskmanagement is necessary. Riskmanagement system will be simple, accessible and promote communication of information to all relevant stakeholders for optimal resource allocation and risk mitigation. Riskmanagement should be used by all team members to managerisks -- risk office personnel. Each group is assigned Risk Integrators who are facilitators for effective riskmanagement. Risks will be managed at the lowest-level feasible, elevate only those risks that require coordination or management from above. Risk reporting and communication is an essential element of riskmanagement and will combine both qualitative and quantitative elements. Risk informed decision making should be introduced to all levels of management. Provide necessary checks and balances to insure that risks are caught/identified and dealt with in a timely manner. Many supporting tools, processes & training must be deployed for effective riskmanagement implementation. Process improvement must be included in the risk processes.
Riskmanagement proactively assesses the potential risks and benefits of health care interventions, including both drugs and medical devices. Riskmanagement systematically identifies safety indications and establishes a riskmanagement strategy for potential adverse events. Professionals trained in riskmanagement have unique expertise in assessing the balance between risk and benefit. They play an important role in clinical study oversight

We view riskmanagement as an integral part of good management. Riskmanagement should take a balanced view of decision problems encompassing all significant risks and rewards. Operational risks are only one type of risks and therefore are only one piece in the jigsaw puzzle that only makes sense when all pieces are assembled. All risk analyses are based on

The increased need to manage California?s electricity grid in real time is a result of the ongoing transition from a system operated by vertically-integrated utilities serving native loads to one operated by an independent system operator supporting competitive energy markets. During this transition period, the traditional approach to reliabilitymanagement -- construction of new transmission lines -- has not been pursued due to unresolved issues related to the financing and recovery of transmission project costs. In the absence of investments in new transmission infrastructure, the best strategy for managingreliability is to equip system operators with better real-time information about actual operating margins so that they can better understand and manage the risk of operating closer to the edge. A companion strategy is to address known deficiencies in offline modeling tools that are needed to ground the use of improved real-time tools. This project: (1) developed and conducted first-ever demonstrations of two prototype real-time software tools for voltage security assessment and phasor monitoring; and (2) prepared a scoping study on improving load and generator response models. Additional funding through two separate subsequent work authorizations has already been provided to build upon the work initiated in this project.

Schools cannot eliminate all risks but can manage them so they minimally affect the "bottom line." A sound risk-management program has four categories: risk avoidance, control, transfer, and retention. Schools retain some risk in situations when insurance is unavailable, costs are negligible, or loss probabilities are remote. (MLH)
Riskmanagement requires an assessment or a knowledge of risk. This, in turn, requires identification of hazards (sources of risk) and a determination of risk (evaluation of the hazard degree). The hazard identification and risk analysis techniques presented in this Guide are, in general, based on the MORT concept that accidents result from unwanted energy flow in the absence of

A formal method is described to quantify structural reliability and risk in the presence of a multitude of uncertainties. The method is based on the materials behavior level where primitive variables with their respective scatters are used to describe that behavior. Computational simulation is then used to propagate those uncertainties to the structural scale where reliability and risk are usually specified. A sample case is described to illustrate the effectiveness, versatility, and maturity of the method. Typical results from this method demonstrate that the method is mature and that it can be used for future strategic projections and planning to assure better, cheaper, faster products for competitive advantages in world markets. The results also indicate that the methods are suitable for predicting remaining life in aging or deteriorating structures.

Derivation of the result- ing Hamilton-Jacobi-Bellman integro-variational equation is discussed, including approximations for Risk representation and heuristic methods of solving from automated (supervised\\/reinforced) learn- ing.
The rapid pace of change at Ike end of the 20th Century should continue unabated well into the 21st Century. The driver will be the marketplace imperative of "faster, better, cheaper." This imperative has already stimulated a revolution-in-engineering in design and manufacturing. In contrast, to date, reliability engineering has not undergone a similar level of change. It is critical that we implement a corresponding revolution-in-reliability-engineering as we enter the new millennium. If we are still using 20th Century reliability approaches in the 21st Century, then reliability issues will be the limiting factor in faster, better, and cheaper. At the heart of this reliability revolution will be a science-based approach to reliability engineering. Science-based reliability will enable building-in reliability, application-specific products, virtual qualification, and predictive maintenance. The purpose of this paper is to stimulate a dialogue on the future of reliability engineering. We will try to gaze into the crystal ball and predict some key issues that will drive reliability programs in the new millennium. In the 21st Century, we will demand more of our reliability programs. We will need the ability to make accurate reliability predictions that will enable optimizing cost, performance and time-to-market to meet the needs of every market segment. We will require that all of these new capabilities be in place prior to the stint of a product development cycle. The management of reliability programs will be driven by quantifiable metrics of value added to the organization business objectives.

The purpose of the Programmatic RiskManagement System (PRMS) is to evaluate and manage potential risks associated with proposed projects (i.e., new products or processes, or possible research and technological development projects). Although the PRMS considers some technical aspects of risk, the primary focus of the methodology is programmatic risk. That is, the methodology permits an assessment of risks associated with such issues as the ability to successfully produce a product that performs in accordance with all customer requirements, and the availability and allocation of resources (money, equipment, facilities, skilled personnel). The PRMS process consists of five formalized activities that are essential for effective management of risks associated with proposed projects. These activities include risk assessment, development of appropriate risk mitigation strategies, estimating strategy implementation cost, ranking of risk mitigation strategies for resource allocation, and scheduling of strategy implementing. The PRMS utilizes a ranking system that allows the user to identify the most cost-effective investment of resources of minimizing risk.

A probabilistic method is used to evaluate the structural reliability and risk of select metallic and composite structures. The method is a multiscale, multifunctional and it is based on the most elemental level. A multifactor interaction model is used to describe the material properties which are subsequently evaluated probabilistically. The metallic structure is a two rotor aircraft engine, while the composite structures consist of laminated plies (multiscale) and the properties of each ply are the multifunctional representation. The structural component is modeled by finite element. The solution method for structural responses is obtained by an updated simulation scheme. The results show that the risk for the two rotor engine is about 0.0001 and the composite built-up structure is also 0.0001.

Adaptation assessment methods are compatible with the international riskmanagement standard ISO:31000. Riskmanagement approaches are increasingly being recommended for adaptation assessments at both national and local levels. Two orientations to assessments can commonly be identified: top-down and bottom-up, and prescriptive and diagnostic. Combinations of these orientations favor different types of assessments. The choice of orientation can be related to uncertainties in prediction and taking action, in the type of adaptation and in the degree of system stress. Adopting multiple viewpoints is to be encouraged, especially in complex situations. The bulk of current guidance material is consistent with top-down and predictive approaches, thus is most suitable for risk scoping and identification. Abroad range ofmaterial fromwithin and beyond the climate change literature can be used to select methods to be used in assessing and implementing adaptation. The framing of risk, correct formulation of the questions being investigated and assessment methodology are critical aspects of the scoping phase. Only when these issues have been addressed should be issue of specific methods and tools be addressed. The reorientation of adaptation from an assessment focused solely on anthropogenic climate change to broader issues of vulnerability/resilience, sustainable development and disaster risk, especially through a riskmanagement framework, can draw from existing policy and management understanding in communities, professions and agencies, incorporating existing agendas, knowledge, risks, and issues they already face.

Various NASA Langley Research Center and other center projects were attempted for analysis to obtain historical data comparing pre-phase A study and the final outcome for each project. This attempt, however, was abandoned once it became clear that very little documentation was available. Next, extensive literature search was conducted on the role of risk and reliability concepts in project management. Probabilistic risk assessment (PRA) techniques are being used with increasing regularity both in and outside of NASA. The value and the usage of PRA techniques were reviewed for large projects. It was found that both civilian and military branches of the space industry have traditionally refrained from using PRA, which was developed and expanded by nuclear industry. Although much has changed with the end of the cold war and the Challenger disaster, it was found that ingrained anti-PRA culture is hard to stop. Examples of skepticism against the use of riskmanagement and assessment techniques were found both in the literature and in conversations with some technical staff. Program and project managers need to be convinced that the applicability and use of riskmanagement and risk assessment techniques is much broader than just in the traditional safety-related areas of application. The time has come to begin to uniformly apply these techniques. The whole idea of risk-based system can maximize the 'return on investment' that the public demands. Also, it would be very useful if all project documents of NASA Langley Research Center, pre-phase A through final report, are carefully stored in a central repository preferably in electronic format.
Software riskmanagement is important because it helps avoid disasters, rework, and overkill, but more importantly because it stimulates win-win situations. The objectives of software riskmanagement are to identify, address, and eliminate software risk items before they become threats to success or major sources of rework. In general, good project managers are also good managers of risk. It makes good business sense for all software development projects to incorporate riskmanagement as part of project management. The Software Assurance Technology Center (SATC) at NASA GSFC has been tasked with the responsibility for developing and teaching a systems level course for riskmanagement that provides information on how to implement riskmanagement. The course was developed in conjunction with the Software Engineering Institute at Carnegie Mellon University, then tailored to the NASA systems community. This is an introductory tutorial to continuous riskmanagement based on this course. The rational for continuous riskmanagement and how it is incorporated into project management are discussed. The riskmanagement structure of six functions is discussed in sufficient depth for managers to understand what is involved in riskmanagement and how it is implemented. These functions include: (1) Identify the risks in a specific format; (2) Analyze the risk probability, impact/severity, and timeframe; (3) Plan the approach; (4) Track the risk through data compilation and analysis; (5) Control and monitor the risk; (6) Communicate and document the process and decisions.
Riskmanagement has been established as a well defined procedure for handling risks due to natural, environmental or man made hazards, of which floods are representative. Riskmanagement has been discussed in many previous papers giving different meanings to the term—a result of the fact that riskmanagement actually takes place on three different levels of actions: the operational level,
Most organizations manage computer security risk reactively by investing in technologies designed to protect against known system vulnerabilities and monitor intrusions as they occur. However, firewalls, cryptography, and antivirus protection address the symptoms, not the root cause, of most security problems.

Most independent power financial proposals contain one or more elements of a non-recourse nature. Traditionally, this means prospective lenders will not have a substantial corporate credit or state guarantee standing behind a project loan, which forces attention to be focused on a single asset as the security and debt repayment source. While this major risk remains present, if properly understood, uncertainty can be mitigated and managed, including financial and development hazards inherent in hydropower projects. The specific risk points that a project developer or sponsor must satisfy from the lender`s purposes are numerous. However, they can be grouped primarily into seven key risk areas: project profile, site securing, power sales agreements, government agreements, in-service management, construction and insurance. While a developer strives for a minimum internal rate of return of at least 20 percent, the lender`s expectations are much more modest. Often, developers need to place themselves in the proverbial shoes of the other entity, namely the independent lender, whose only attraction may be some interest, fee income and placement of capital in a safe investment which provides a return in an orderly and uninterrupted manner. Only then is it possible to objectively view and effectively manage the risks mentioned earlier.

The overall objectives of a research project were to: determine distribution reliability assessment methods currently used by the industry; develop a general outage reporting scheme suitable for a wide variety of distributing utilities (reliability model); develop a model for predicting the reliability of future system configurations (risk model); and compile a handbook of reliability assessment methods designed specifically for use by the practicing distribution engineer. Emphasis was placed on compiling and organizing reliability assessment techniques presently used by the industry. The project examined reliability evaluation from two perspectives: historical and predictive assessment. Two reliability assessment models, HISRAM - the historical reliability assessment model and PRAM - the predictive reliability assessment model were developed. Each model was tested in a utility environment by the Duquesne Light Company and the Public Service Electric and Gas Company of New Jersey. A survey of 56 diverse utilities served as a basis for examining current distribution reliability assessment practices in the electric power industry.

Program Managers (PM) can protect program resources and improve chances of success by anticipating, understanding and managingrisks. Understanding the range of potential risks helps one to avoid or manage the risks. A PM must choose which risks to accept to reduce fire fighting, must meet the expectations of stakeholders consistently, and avoid falling into costly "black holes" that may open. A good riskmanagement process provides the PM more confidence to seize opportunities save money, meet schedule, even improve relationships with people important to the program. Evidence of managingrisk and sound internal controls can mean better support from superiors for the program by building a trust and reputation from being on top of issues. Riskmanagers have an obligation to provide the PM with the best information possible to allow the benefits to be realized (Small Business Consortium, 2004). The Institute for Chartered Accountants in England and Wales sees very important benefits for companies in providing better information about what they do to assess and manage key business risks. Such information will: a) provide practical forward-looking information; b) reduce the cost of capital; c) encourage better riskmanagement; and d) improve accountability for stewardship, investor protection and the usefulness of financial reporting. We are particularly convinced that enhanced risk reporting will help listed companies obtain capital at the lowest possible cost (The Institute of Chartered Accountants in England &Wales, June 2002). Riskmanagers can take a significant role in quantifying the success of their department and communicating those figures to executive (program) management levels while pushing for a broader riskmanagement role. Overall, riskmanagers must show that riskmanagement work matters in the most crucial place-the bottom line- as they prove riskmanagement can be a profit center (Sullivan, 2004).
In a time of shrinking resources policy makers and administrators in Child Protective Services are increasingly turning to tools such as structured risk assessment to manage service demand. The reliability and predictive validity of risk assessment is questionable, however, and concerns continue about the validity of using lists of explicit criteria in protective services decision-making. In this research the issues
Information Technology (IT) Security RiskManagement is a critical task for the organization to protect against the loss of confidentiality, integrity and availability of IT resources. As systems bgecome more complex and diverse and and attacks from intrusions and malicious content increase, it is becoming increasingly difficult to manage IT security risk. This paper describes a two-pronged approach in addressing IT security risk and riskmanagement in the organization: 1) an institutional enterprise appraoch, and 2) a project life cycle approach.
Clinical laboratory tests play an integral role in medical decision-making and as such must be reliable and accurate. Unfortunately, no laboratory tests or devices are foolproof and errors can occur at pre-analytical, analytical and post-analytical phases of testing. Evaluating possible conditions that could lead to errors and outlining the necessary steps to detect and prevent errors before they cause patient harm is therefore an important part of laboratory testing. This can be achieved through the practice of riskmanagement. EP23-A is a new guideline from the CLSI that introduces riskmanagement principles to the clinical laboratory. This guideline borrows concepts from the manufacturing industry and encourages laboratories to develop riskmanagement plans that address the specific risks inherent to each lab. Once the risks have been identified, the laboratory must implement control processes and continuously monitor and modify them to make certain that risk is maintained at a clinically acceptable level. This review summarizes the principles of riskmanagement in the clinical laboratory and describes various quality control activities employed by the laboratory to achieve the goal of reporting valid, accurate and reliable test results.

The authors describe how NASA appears to be undergoing a paradigm shift in its approach to Space Shuttle riskmanagement. At least in some quarters, there appears to be a recognition that advances in the state-of-the-art have now made quantitative risk assessments powerful riskmanagement tools, especially for programs such as the Shuttle with its ever increasing flight and test
In developed nations, the workforce is aging rapidly. That trend has serious implications. Companies could face severe labor shortages in a few years as workers retire, taking critical knowledge with them. Businesses may also see productivity decline among older employees, especially in physically demanding jobs. The authors, partners at Boston Consulting Group, offer managers a systematic way to assess these dual threats--capacity risk and productivity risk--at their companies. It involves studying the age distribution of their employees to see if large percentages fall within high age brackets and then projecting--by location, unit, and job category--how the distribution will change over the next 15 years. Managers must also factor in both the impact of strategic moves on personnel needs and the future supply of workers in the market. When RWE Power analyzed its trends, the company learned that in 2018 almost 80% of its workers would be over 50. What's more, in certain critical areas its labor surplus was about to become a sizable shortfall. For instance, a shortage of specialized engineers would develop in the company just as their ranks in the job market thinned and competition to hire them intensified. Reversing its downsizing course, RWE Power took steps to increase its supply of workers in those key positions. The authors show how companies that face talent gaps, as RWE Power did, can close them through training, transfers, recruitment, retention, productivity improvements, and outsourcing. They also describe measures that companies can take to keep older workers productive, including workplace accommodations, revised compensation structures, performance incentives, and targeted health care management. The key is to identify and address potential problems early. Firms that do so will gain an edge on rivals that are still relentlessly focused on reducing head count. PMID:18314640

This paper summarizes the intermediate lessons learned from the analyses of the riskmanagement problems in three technological endeavors. These problems are: the absence of a structure for rewarding successful project riskmanagement; the need for an ever-more accurate economic measure of risk; and the difficulty of transferring risks to contract-bound independent outsourcing entity. This paper also describes recent advancement towards providing answers to these challenges and future research endeavors in this field.
Sandia National Laboratories has assembled an interdisciplinary team to explore the applicability of probabilistic logic modeling (PLM) techniques to model network reliability for a wide variety of communications network architectures. The authors have found that the reliability and failure modes of current generation network technologies can be effectively modeled using fault tree PLM techniques. They have developed a ``plug-and-play`` fault tree analysis methodology that can be used to model connectivity and the provision of network services in a wide variety of current generation network architectures. They have also developed an efficient search algorithm that can be used to determine the minimal cut sets of an arbitrarily-interconnected (non-hierarchical) network without the construction of a fault tree model. This paper provides an overview of these modeling techniques and describes how they are applied to networks that exhibit hybrid network structures (i.e., a network in which some areas are hierarchical and some areas are not hierarchical).
This paper presents a reliability analysis method for safety evaluation of nuclear structures. By utilizing this method, it is possible to estimate the limit state probability in the lifetime of structures and to generate analytically the fragility curves for PRA studies. The earthquake ground acceleration, in this approach, is represented by a segment of stationary Gaussian process with a zero mean and a Kanai-Tajimi Spectrum. All possible seismic hazard at a site represented by a hazard curve is also taken into consideration. Furthermore, the limit state of a structure is analytically defined and the corresponding limit state surface is then established. Finally, the fragility curve is generated and the limit state probability is evaluated. In this paper, using a realistic reinforced concrete containment as an example, results of the reliability analysis of the containment subjected to dead load, live load and ground earthquake acceleration are presented and a fragility curve for PRA studies is also constructed.
NPG 7120.5A, "NASA Program and Project Management Processes and Requirements" enacted in April, 1998, requires that "The program or project manager shall apply riskmanagement principles..." The Software Assurance Technology Center (SATC) at NASA GSFC has been tasked with the responsibility for developing and teaching a systems level course for riskmanagement that provides information on how to comply with this edict. The course was developed in conjunction with the Software Engineering Institute at Carnegie Mellon University, then tailored to the NASA systems community. This presentation will briefly discuss the six functions for riskmanagement: (1) Identify the risks in a specific format; (2) Analyze the risk probability, impact/severity, and timeframe; (3) Plan the approach; (4) Track the risk through data compilation and analysis; (5) Control and monitor the risk; (6) Communicate and document the process and decisions. This riskmanagement structure of functions has been taught to projects at all NASA Centers and is being successfully implemented on many projects. This presentation will give project managers the information they need to understand if riskmanagement is to be effectively implemented on their projects at a cost they can afford.
To facilitate the implementation of the RiskManagement Plan, the Next Generation Nuclear Plant (NGNP) Project has developed and employed an analytical software tool called the NGNP RiskManagement System (RMS). A relational database developed in Microsoft® Access, the RMS provides conventional database utility including data maintenance, archiving, configuration control, and query ability. Additionally, the tool’s design provides a number of unique capabilities specifically designed to facilitate the development and execution of activities outlined in the RiskManagement Plan. Specifically, the RMS provides the capability to establish the risk baseline, document and analyze the risk reduction plan, track the current risk reduction status, organize risks by reference configuration system, subsystem, and component (SSC) and Area, and increase the level of NGNP decision making.
Reservoir systems are subject to several uncertainties that are the result of imperfect knowledge about system behavior and inputs. A major source of uncertainty is the inability to precisely predict future inflows, especially as the management horizon increases. Fortunately, there often exists enough information from historical records and/or hydroclimatic models to generate probabilistic forecasts of inflow volumes in the form of probability density functions or ensembles. These inflow forecasts can be coupled with stochastic management models to help operate reservoir systems and provide stakeholders with probabilistic forecasts of system variables, such as reservoir storages, releases, hydropower production, water withdrawals, and water quality parameters. It is important for forecasts to provide dependable descriptions of the actual system variables that eventually occur since consistently misrepresenting these variables will provide inadequate or misleading information about expected benefits and risks. The first part of this study presents an assessment technique that can be used to determine the reliability of one and multi-dimensional ensemble forecasts through the use of relative frequency histograms and minimum spanning trees (MST). The technique is then used to assess the extended Gaussian linear quadrature (ELQG) management model and determine its ability to produce reliable ensemble forecast of reservoir system variables. Extensions of the existing model are discussed and evaluated. The second portion of this study concerns the management of the uncertainty distribution across a reservoir system. The large majority of stochastic management models only consider optimizing the expected benefits, thereby not allowing operators and stakeholders to explicitly choose or explore issues such as variable variability and risk avoidance. An iterative framework that allows stakeholders to trade-off risks and uncertainties is developed by using objective function reformulations that constrain variable variances. This framework can be used to derive different management policies that produce desired probabilistic behaviors of the entire reservoir system or its individual sub-components and objectives. The methods developed in this study are illustrated on real reservoir systems including a 7-reservoir multi-objective system in California's Central Valley.

This presentation sets the context by providing basic statistics and considers some of the main preoccupations over the last decade which include the growth of numbers of women in prison, concern for the vulnerability of women offenders, recognition of gender-specific needs and diversion from custody. Managing women in prison involved understanding the pathways to offending, resettlement needs and risks; and the "connecting threads of life history" on the pathway to offending were described. Understanding risk meant being concerned about risk of harm to self as well as to others, intergenerational risk, as well as risk of re-offending. Options for addressing these needs and risks were discussed. PMID:22761358
Current geometric design guides provide deterministic standards where the safety margin of the design output is generally unknown and there is little knowledge of the safety implications of deviating from these standards. Several studies have advocated probabilistic geometric design where reliability analysis can be used to account for the uncertainty in the design parameters and to provide a risk measure of the implication of deviation from design standards. However, there is currently no link between measures of design reliability and the quantification of safety using collision frequency. The analysis presented in this paper attempts to bridge this gap by incorporating a reliability-based quantitative risk measure such as the probability of non-compliance (P(nc)) in safety performance functions (SPFs). Establishing this link will allow admitting reliability-based design into traditional benefit-cost analysis and should lead to a wider application of the reliability technique in road design. The present application is concerned with the design of horizontal curves, where the limit state function is defined in terms of the available (supply) and stopping (demand) sight distances. A comprehensive collision and geometric design database of two-lane rural highways is used to investigate the effect of the probability of non-compliance on safety. The reliability analysis was carried out using the First Order Reliability Method (FORM). Two Negative Binomial (NB) SPFs were developed to compare models with and without the reliability-based risk measures. It was found that models incorporating the P(nc) provided a better fit to the data set than the traditional (without risk) NB SPFs for total, injury and fatality (I+F) and property damage only (PDO) collisions.

Thousands of safety issues have been collected on-line at the Idaho National Engineering and Environmental Laboratory (INEEL) as part of the Issue Management Plan. However, there has been no established approach to prioritize collected and future issues. The authors developed a methodology, based on hazards assessment, to identify and risk rank over 5000 safety issues collected at INEEL. This approach required that it was easily applied and understandable for site adaptation and commensurate with the Integrated Safety Plan. High-risk issues were investigated and mitigative/preventive measures were suggested and ranked based on a cost-benefit scheme to provide risk-informed safety measures. This methodology was consistent with other integrated safety management goals and tasks providing a site-wide risk informed decision tool to reduce hazardous conditions and focus resources on high-risk safety issues. As part of the issue management plan, this methodology was incorporated at the issue collection level and training was provided to management to better familiarize decision-makers with concepts of safety and risk. This prioritization methodology and issue dissemination procedure will be discussed. Results of issue prioritization and training efforts will be summarized. Difficulties and advantages of the process will be reported. Development and incorporation of this process into INEELs lessons learned reporting and the site-wide integrated safety management program will be shown with an emphasis on establishing self reliance and ownership of safety issues.

Advanced probability models are used to evaluate risks and to justify decisions where reliable data is available, e.g. reinsurance, money markets and nuclear energy. Operational riskmanagement – the trade-offs made to run an efficient and effective organisation – has much less, and lower quality, data. In the first part of the paper, observations are made about the factors shaping
The Short-Term Assessment of Risk and Treatability (START) is a relatively new structured professional judgment guide for the assessment and management of short-term risks associated with mental, substance use, and personality disorders. The scheme may be distinguished from other violence risk instruments because of its inclusion of 20 dynamic factors that are rated in terms of both vulnerability and strength. This study examined the reliability and validity of START assessments in predicting inpatient aggression. Research assistants completed START assessments for 120 male forensic psychiatric patients through review of hospital files. They additionally completed Historical-Clinical-RiskManagement – 20 (HCR-20) and the Hare Psychopathy Checklist: Screening Version (PCL:SV) assessments. Outcome data was coded from hospital files for a 12-month follow-up period using the Overt Aggression Scale (OAS). START assessments evidenced excellent interrater reliability and demonstrated both predictive and incremental validity over the HCR-20 Historical subscale scores and PCL:SV total scores. Overall, results support the reliability and validity of START assessments, and use of the structured professional judgment approach more broadly, as well as the value of using dynamic risk and protective factors to assess violence risk.

The objective of ICH Q8, Q9 and Q10 documents is application of systemic and science based approach to formulation development for building quality into product. There is always some uncertainty in new product development. Good riskmanagement practice is essential for success of new product development in decreasing this uncertainty. In quality by design paradigm, the product performance properties relevant to the patient are predefined in target product profile (TPP). Together with prior knowledge and experience, TPP helps in identification of critical quality attributes (CQA's). Initial risk assessment which identifies risks to these CQA's provides impetus for product development. Product and process are designed to gain knowledge about these risks, devise strategies to eliminate or mitigate these risks and meet objectives set in TPP. By laying more emphasis on high risk events the protection level of patient is increased. The process being scientifically driven improves the transparency and reliability of the manufacturer. The focus on risk to the patient together with flexible development approach saves invaluable resources, increases confidence on quality and reduces compliance risk. The knowledge acquired in analysing risks to CQA's permits construction of meaningful design space. Within the boundaries of the design space, variation in critical material characteristics and process parameters must be managed in order to yield a product having the desired characteristics. Specifications based on product and process understanding are established such that product will meet the specifications if tested. In this way, the product is amenable to real time release, since specifications only confirm quality but they do not serve as a means of effective process control. PMID:22757979
In distributed workflow management systems (WfMSs) many workflow servers and clients should work together cooperatively using client\\/server communication.

The selection of climate policies should be an exercise in riskmanagement reflecting the many relevant sources of uncertainty. Studies of climate change and its impacts rarely yield consensus on the distribution of exposure, vulnerability or possible outcomes. Hence policy analysis cannot effectively evaluate alternatives using standard approaches, such as expected utility theory and benefit-cost analysis. This Perspective highlights the value of robust decision-making tools designed for situations such as evaluating climate policies, where consensus on probability distributions is not available and stakeholders differ in their degree of risk tolerance. A broader risk-management approach enables a range of possible outcomes to be examined, as well as the uncertainty surrounding their likelihoods.

The focus of the NASA 'Space Flight Risk Data Collection and Analysis' project was to acquire and evaluate space flight data with the express purpose of establishing a database containing measurements of specific risk assessment - reliability - availability - maintainability - supportability (RRAMS) parameters. The developed comprehensive RRAMS database will support the performance of future NASA and aerospace industry risk and reliability studies. One of the primary goals has been to acquire unprocessed information relating to the reliability and availability of launch vehicles and the subsystems and components thereof from the 45th Space Wing (formerly Eastern Space and Missile Command -ESMC) at Patrick Air Force Base. After evaluating and analyzing this information, it was encoded in terms of parameters pertinent to ascertaining reliability and availability statistics, and then assembled into an appropriate database structure.
It is important to the Space Shuttle Program (SSP), as well as future manned spaceflight programs, to understand the early mission risk and progression of risk as the program gains insights into the integrated vehicle through flight. The risk progression is important to the SSP as part of the documentation of lessons learned. The risk progression is important to future programs to understand reliability growth and the first flight risk. This analysis uses the knowledge gained from 30 years of operational flights and the current Shuttle PRA to calculate the risk of Loss of Crew and Vehicle (LOCV) at significant milestones beginning with the first flight. Key flights were evaluated based upon historical events and significant re-designs. The results indicated that the Shuttle risk tends to follow a step function as opposed to following a traditional reliability growth pattern where risk exponentially improves with each flight. In addition, it shows that risk can increase due to trading safety margin for increased performance or due to external events. Due to the risk drivers not being addressed, the risk did not improve appreciably during the first 25 flights. It was only after significant events occurred such as Challenger and Columbia, where the risk drivers were apparent, that risk was significantly improved. In addition, this paper will show that the SSP has reduced the risk of LOCV by almost an order of magnitude. It is easy to look back afte r 30 years and point to risks that are now obvious, however; the key is to use this knowledge to benefit other programs which are in their infancy stages. One lesson learned from the SSP is understanding risk drivers are essential in order to considerably reduce risk. This will enable the new program to focus time and resources on identifying and reducing the significant risks. A comprehensive PRA, similar to that of the Shuttle PRA, is an effective tool quantifying risk drivers if support from all of the stakeholders is given.

This paper describes recent work on developing an extensible information grid for riskmanagement at NASA - a RISK INFORMATION GRID. This grid is being developed by integrating information grid technology with riskmanagement processes for a variety of risk related applications. To date, RISK GRID applications are being developed for three main NASA processes: riskmanagement - a closed-loop iterative process for explicit riskmanagement, program/project management - a proactive process that includes riskmanagement, and mishap management - a feedback loop for learning from historical risks that escaped other processes. This is enabled through an architecture involving an extensible database, structuring information with XML, schemaless mapping of XML, and secure server-mediated communication using standard protocols.
NASA requires continuous riskmanagement for all programs and projects. The riskmanagement process identifies risks, analyzes their impact, prioritizes them, develops and carries out plans to mitigate or accept them, tracks risks and mitigation plans, and communicates and documents risk information. Project riskmanagement is driven by the project goal and is performed by the entire team. Riskmanagement begins early in the formulation phase with initial risk identification and development of a riskmanagement plan and continues throughout the project life cycle. This paper describes the riskmanagement approach that is suggested for use in NASA's Human Support Technology Development. The first step in riskmanagement is to identify the detailed technical and programmatic risks specific to a project. Each individual risk should be described in detail. The identified risks are summarized in a complete risk list. Risk analysis provides estimates of the likelihood and the qualitative impact of a risk. The likelihood and impact of the risk are used to define its priority location in the risk matrix. The approaches for responding to risk are either to mitigate it by eliminating or reducing the effect or likelihood of a risk, to accept it with a documented rationale and contingency plan, or to research or monitor the risk, The Human Support Technology Development program includes many projects with independently achievable goals. Each project must do independent riskmanagement, considering all its risks together and trading them against performance, budget, and schedule. Since the program can succeed even if some projects fail, the program risk has a complex dependence on the individual project risks.

A construction project is about the riskiest thing any company does in the normal course of business. Hundreds of things can go wrong, dozens will. But officers who analyze and manage every other sort of risk often ignore construction risk as if it were uncontrollable. The truth is, it can't be eliminated, but it can be controlled. Construction is not a product but a confusing and often exasperating service. A group of experts--architects, bankers, consultants, contractors, engineers, users, city officials--coordinate the activities of an army of suppliers, laborers, designers, subcontractors, and inspectors. The job of the company officers is to coordinate the coordinators; to make prompt, informed decisions as the work progresses; to take and retain project responsibility at the highest level; and to analyze and manage the entire process in the following seven stages: 1. Study the types and phases of construction risk. 2. Assess the risks of the company's particular project. 3. Match these risks with the in-house capabilities. 4. Define a building strategy. 5. Pick the right kind of contract. 6. Choose a contractor. 7. Monitor construction. Analyzing risk is largely a matter of assessing the complexity of the building, the site, the financing, the schedule, and the special uses and problems of the project. This analysis then drives the choice of contract and contractor. The range runs from low-cost providers, lump sum contracts and very little teamwork at one end of the spectrum to highly differentiated construction companies, guaranteed-maximum-prince contracts, and consultative coordination at the other.

Purpose – Global supply chains are more risky than domestic supply chains due to numerous links interconnecting a wide network of firms. These links are prone to disruptions, bankruptcies, breakdowns, macroeconomic and political changes, and disasters leading to higher risks and making riskmanagement difficult. The purpose of this paper is to explore the phenomenon of riskmanagement and risk
Operational riskmanagement (ORM) is a process of critical importance to organizations. It refers to the systematic identification, assessment and mitigation of operational risks, i.e. risks stemming from processes, people, systems or external events. ORM is performed through different systems in the different business units of the enterprise - however a unified view of the operational riskmanagement information is
The goal of RiskManagement activities is to define prevention and control mechanisms to address the risks attached to specify activities and valuable assets. Many RiskManagement efforts operate in silos with narrowly focused, functionally driven, and disjointed activities. That fact leads to a fragmented view of risks, where each activity uses its own language, customs and metrics. The lack
With rapid economic development and the progressively more intense competition, building industries are facing the constant change, and these will bring risk to the enterprise development.

Riskmanagement practices under the current environmental regulations is a long, complex process that considers scientific, technologic, and management factors to develop various regulatory standards and pollution control measures. Using the mandatory enforcement approach, sometimes referred to as “command-and-control”, a set of preliminary environmental goals, such as better air and water qualities, were achieved. However, the information-intensive nature of the riskmanagement process and the lack of flexibility in conventional regulatory methods to changing economic and technologic realities of the decade has created interest among riskmanagers to examine some innovative management approaches. Above all, environmental problems of a global scale require novel management methods while striving to achieve the desired environmental goals. As the principal analytical tool in riskmanagement, quantitative risk assessment exerts considerable influence on the riskmanagement process. Therefore, advances in riskmanagement are closely associated with scientific developments that enhance the risk assessment process, particularly those efforts aimed at improving human exposure and toxicity assessments. Market incentives, information dissemination, creative enforcement practices, and interagency and intergovernmental interactions were identified as the key elements of innovative environmental riskmanagement practices. This paper will present an overview of the emerging innovative riskmanagement approaches.

Enterprise riskmanagement has become an important consideration in all aspects of business, including production planning. Business risk scorecards are important tools to monitor the performance of organisations. This article demonstrates the value of business scorecards as a means to monitor organisational performance with respect to riskmanagement. A small bank credit loan case is used to make this demonstration.
The Idaho National Engineering and Environmental Laboratory (INEEL) is investigating the development of a comprehensive and quantitative risk model framework for environmental management activities at the site. Included are waste management programs (high-level waste, transuranic waste, low-level waste, mixed low-level waste, spent nuclear fuel, and special nuclear materials), major environmental restoration efforts, major decontamination and decommissioning projects, and planned long-term stewardship activities. Two basic types of risk estimates are included: risks from environmental management activities, and long-term legacy risks from wastes/materials. Both types of risks are estimated using the Environment, Safety, and Health Risk Assessment Program (ESHRAP) developed at the INEEL. Given these two types of risk calculations, the following evaluations can be performed: • Risk evaluation of an entire program (covering waste/material as it now exists through disposal or other end states) • Risk comparisons of alternative programs or activities • Comparisons of risk benefit versus risk cost for activities or entire programs • Ranking of programs or activities by risk • Ranking of wastes/materials by risk • Evaluation of site risk changes with time as activities progress • Integrated performance measurement using indicators such as injury/death and exposure rates. This paper discusses the definition and calculation of legacy risk measures and associated issues. The legacy risk measure is needed to support three of the seven types of evaluations listed above: comparisons of risk benefit versus risk cost, ranking of wastes/materials by risk, and evaluation of site risk changes with time.
Mergers are big, risky business and they frequently fail. This article reviews the literature around managing human resource management (HRM) risk in a merger. It finds that poor merger results are often attributed to HRM and organisational problems, and that several factors related to maintaining workforce stability are identified as important in managing HRM risk. Gaps are exposed in the
For several years, as floods were increasing in South of France, local communities felt deprive to assume their mission of protection and information of citizens, and were looking for assistance in flood management. In term of flood disaster, the fact is that physical protection is necessary but inevitably limited. Tools and structures of assistance to anticipation remain slightly developed. To manage repeated crisis, local authorities need to be able to base their policy against flood on prevention, warnings, post-crisis analysis and feedback from former experience. In this objective, after 3 years of test and improvement since 2003, the initiative Predict-Services was developed in South of France: it aims at helping communities and companies to face repeated flood crisis. The principle is to prepare emergency plans, to organize crisis management and reduce risks; to help and assist communities and companies during crisis to activate and adapt their emergency plans with enough of anticipation; and to analyse floods effects and improve emergency plans afterwards. With the help of Meteo France datas and experts, Predict services helps local communities and companies in decision making for flood management. In order to reduce risks, and to keep the benefits of such an initiative, local communities and companies have to maintain the awareness of risk of the citizens and employees. They also have to maintain their safety plans to keep them constantly operational. This is a part of the message relayed. Companies, Local communities, local government authorities and basin stakeholders are the decision makers. Companies and local communities have to involve themselves in the elaboration of safety plans. They are also completely involved in their activation that is their own responsability. This applies to other local government authorities, like districts one's and basin stakeholders, which participle in the financing community safety plans and adminitrative district which are responsible of the transmission of meteorological alert and of rescue actions. In the crossing of the géo-information stemming from the space technology, communication, meteorology, hydraulics and hydrology, Predict-services brings help to local communities in their mission of protection and information to the citizens, for flood problems and helps companies to limit and delete operating losses facing floods. The initiative, developped by BRL, EADS Astrium, in association with Meteo France, has been employed and is functioning on cities of south of France, notably on Montpellier, and also on the scale of catchment area ( BRL is a regional development company, a public private partnership controlled by the local gouvernments of the Languedoc-Roussillon Region). The initiative has to be coordinated with state services to secure continuity and coherence of information. This initiative is developped in dialogue with State services as Météo France, the Ministry for the interior, the Ministry for ecology and the durable development, the Regional Direction of the Environment (DIREN), the Central service of Hydrometeorology and Support to the Forecast of the Floods ( SCHAPI) and service of forecast of rising (SPC). It has been successfully functioning for 5 years with 300 southern cities from South West to South East of France and notably Montpellier and Sommières, famous for it's flood problems on the Vidourle river where no human loss was to regret and where the economic impacts were minimized. Actually developed in cities of South of France, this initiative is to be developed nationaly and very soon internationally. Thanks to the efficiency of it's method, this initiative is also developed in partnership with insurance company involved in prevention actions. After more than 100 events observed and analysed in South of France, the experience gained, allowed PREDICT Services to better anticipate phenomena and also to better manage them. The presentation will expose the feedback of this initiative and lessons learned on riskmanagement.

NPG 7120.5A, "NASA Program and Project Management Processes and Requirements" enacted in April, 1998, requires that "The program or project manager shall apply riskmanagement principles..." The Software Assurance Technology Center (SATC) at NASA GSFC has been tasked with the responsibility for developing and teaching a systems level course for riskmanagement that provides information on how to comply with this edict. The course was developed in conjunction with the Software Engineering Institute at Carnegie Mellon University, then tailored to the NASA systems community. This presentation will briefly discuss the six functions for riskmanagement: (1) Identify the risks in a specific format; (2) Analyze the risk probability, impact/severity, and timeframe; (3) Plan the approach; (4) Track the risk through data compilation and analysis; (5) Control and monitor the risk; (6) Communicate and document the process and decisions.

The International Space Station (ISS) is an extremely complex system, both technically and programmatically. The Space Station must support a wide range of payloads and missions. It must be launched in numerous launch packages and be safely assembled and operated in the harsh environment of space. It is being designed and manufactured by many organizations, including the prime contractor, Boeing, the NASA institutions, and international partners and their contractors. Finally, the ISS has multiple customers, (e.g., the Administration, Congress, users, public, international partners, etc.) with contrasting needs and constraints. It is the ISS RiskManagement Office strategy to proactively and systematically managesrisks to help ensure ISS Program success. ISS program follows integrated riskmanagement process (both quantitative and qualitative) and is integrated into ISS project management. The process and tools are simple and seamless and permeate to the lowest levels (at a level where effective management can be realized) and follows the continuous riskmanagement methodology. The risk process assesses continually what could go wrong (risks), determine which risks need to be managed, implement strategies to deal with those risks, and measure effectiveness of the implemented strategies. The process integrates all facets of risk including cost, schedule and technical aspects. Support analysis risk tools like PRA are used to support programatic decisions and assist in analyzing risks.

Occupational exposure to engineered nanomaterials (ENMs) is considered a new and challenging occurrence. Preliminary information from laboratory studies indicates that workers exposed to some kinds of ENMs could be at risk of adverse health effects. To protect the nanomaterial workforce, a precautionary riskmanagement approach is warranted and given the newness of ENMs and emergence of nanotechnology, a naturalistic view of riskmanagement is useful. Employers have the primary responsibility for providing a safe and healthy workplace. This is achieved by identifying and managingrisks which include recognition of hazards, assessing exposures, characterizing actual risk, and implementing measures to control those risks. Following traditional riskmanagement models for nanomaterials is challenging because of uncertainties about the nature of hazards, issues in exposure assessment, questions about appropriate control methods, and lack of occupational exposure limits (OELs) or nano-specific regulations. In the absence of OELs specific for nanomaterials, a precautionary approach has been recommended in many countries. The precautionary approach entails minimizing exposures by using engineering controls and personal protective equipment (PPE). Generally, riskmanagement utilizes the hierarchy of controls. Ideally, riskmanagement for nanomaterials should be part of an enterprise-wide riskmanagement program or system and this should include both risk control and a medical surveillance program that assesses the frequency of adverse effects among groups of workers exposed to nanomaterials. In some cases, the medical surveillance could include medical screening of individual workers to detect early signs of work-related illnesses. All medical surveillance should be used to assess the effectiveness of riskmanagement; however, medical surveillance should be considered as a second line of defense to ensure that implemented riskmanagement practices are effective.

Risk and cost trade-offs have been simulated using a probabilistic method. The probabilistic method accounts for all naturally-occurring uncertainties including those in constituent material properties, fabrication variables, structure geometry and loading conditions. The probability density function of first buckling load for a set of uncertain variables is computed. The probabilistic sensitivity factors of uncertain variables to the first buckling load is calculated. The reliability-based cost for a composite fuselage panel is defined and minimized with respect to requisite design parameters. The optimization is achieved by solving a system of nonlinear algebraic equations whose coefficients are functions of probabilistic sensitivity factors. With optimum design parameters such as the mean and coefficient of variation (representing range of scatter) of uncertain variables, the most efficient and economical manufacturing procedure can be selected. In this paper, optimum values of the requisite design parameters for a predetermined cost due to failure occurrence are computationally determined. The results for the fuselage panel analysis show that the higher the cost due to failure occurrence, the smaller the optimum coefficient of variation of fiber modulus (design parameter) in longitudinal direction.

The Right-to-Know Network (RTK Net) has recently placed a large database of summaries (approximately 14,000) of riskmanagement plans (RMPs) concerning "worst-case" and less severe accident scenarios at chemical facilities. The RMPs were required of certain chemical facilities and presented to the US Environmental Protection Agency (EPA), which originally intended to place them online. However, Congress and the White House, spurred on by warnings of security specialists, objected, arguing that this document might serve as a road map to would-be terrorists. The worst-case-scenario information has been exempted from the Freedom of Information Act for one year to allow the Administration time to address these security concerns. RTK Net has made these more easily available in the interest of public awareness and to confront chemical companies that have tried to hide or at least downplay chemical releases. Users can browse the RMPs by state or conduct a keyword search. The About the Data section also offers a number of related links.
In analyzing the stability of a maintenance process, it is important that it not be treated in isolation from the reliability and risk of deploying the software that result from applying the process. Furthermore, we need to consider the efficiency of the test effort that is a part of the process and a determinate of reliability and risk of deployment.

Risks in software systems arise from many directions. There are risks that the software is faulty, that the system may be attacked, that safety hazards exist, that the system may be inoperable or untimely, that an abnormal event may cause unexpected actions, etc. Risk analysis tools should support and document risk-mitigation decisions and facilitate understanding of residual risks. These tools must be based on a sound theory of risk, which does not exist today. Probabilistic risk assessment techniques apply to physically-based systems where failure modes and event dependence are fairly well understood. But they cannot be blindly applied to software systems, which do not share these characteristics. Moreover, we need to meld many diverse aspects of risk for software systems. This presentation will explore some thought-provoking ideas about modeling, problem spaces, solution approaches, math, decision friendly output, and the role of risk analysis in the software lifecycle.
In this article I describe a methodology for the mapping of Operational Risk with the objective of identifying the risks inherent in the different steps of a business process, selecting a set of variables providing an estimate for the likelihood and the severity of operational risk (Key Risk Indicators – KRIs) and designing the most appropriate control activities.

Los Alamos National Laboratory has riskmanagement programs at a number of administrative levels. Each line organization has responsibility for riskmanagement for routine operations. The Facility RiskManagement group (HS-3) is the Los Alamos organization with the primary responsibility for riskmanagement including providing input and expertise to facilities and line managers in the management and documentation of ES&H hazards and risks associated with existing and new activities. One of the major contributions this group has made to laboratory riskmanagement program is to develop and implement a hazard identification and classification methodology that is readily adaptable to continuously changing classification guidelines such as DOE-STD-1027. The increased emphasis on safety at Los Alamos has led to the formation of additional safety oversight organization such as the Integration and Coordination Office (ICO), which is responsible for prioritization of riskmanagement activities. In the fall of 1991, nearly 170 DOE inspectors spent 6 weeks analyzing the environmental, safety, and health activities at Los Alamos. The result of this audit was a list of over 1000 findings, each indicating some deficiency in current Laboratory operations relative to DOE and other government regulation. The audit team`s findings were consolidated and ``action plans`` were developed to address the findings. This resulted in over 200 action plans with a total estimated cost of almost $1 billion. The Laboratory adopted a risk-based prioritization process to attempt to achieve as much risk reduction as possible with the available resources. This paper describes the risk based prioritization model that was developed.

The tragic events of 9/11 and the concerns about the potential for a terrorist or hostile state attack with weapons of mass destruction have led to an increased emphasis on risk analysis for homeland security. Uncertain hazards (natural and engineering) have been successfully analyzed using probabilistic risk analysis (PRA). Unlike uncertain hazards, terrorists and hostile states are intelligent adversaries who can observe our vulnerabilities and dynamically adapt their plans and actions to achieve their objectives. This article compares uncertain hazard risk analysis with intelligent adversary risk analysis, describes the intelligent adversary risk analysis challenges, and presents a probabilistic defender-attacker-defender model to evaluate the baseline risk and the potential risk reduction provided by defender investments. The model includes defender decisions prior to an attack; attacker decisions during the attack; defender actions after an attack; and the uncertainties of attack implementation, detection, and consequences. The riskmanagement model is demonstrated with an illustrative bioterrorism problem with notional data. PMID:20002893

It is shown how the methods of risk analysis have been used in the University of Rome micro-satellite program. One of the driving research topics related to this program is the reduction of cost in building spacecraft. The probability risk analysis techniques seem to be a powerful tool in the field of micro-satellites design, to outline possible faults. Innovation and limited budget forcing the designer to move in a very "risky" environment and can be faced with an as rigorous as possible decision making method. In our project, cost reduction is often attained relying on commercial, not space-rated components, which of course increases risk. This is why the design process should be led by the careful analysis of the risk associated with the selection of components and construction techniques. In standard applications risk can be evaluated from reliability data obtained in previous and well known similar applications. In our case, for many components, there is a lack of reliability data, due to the obvious missing experience when dealing with not yet space qualified, or even never flown before components. This lack is overcome using numerical simulations and practical engineering considerations, but does not allow a rigorous reliability assessment. A simple qualitative analysis is used to rank priorities among subsystems and allocate economic resources and development efforts. The main risk source is space radiation effect on CMOS electronic components. Therefore, development resources are directed to radiation effect mitigation. A procedure is proposed to lower risk without using space rated components.
How much should greenhouse gas emissions be reduced in response to climate change risks? Current regulatory analyses typically adopt a benefit-cost (or the more general optimal economic growth) framework to this question. However, benefit-cost analyses of climate change typically neglect the effects of the deep uncertainties surrounding the projections of future climate change impacts and decision-making criteria. Riskmanagement approaches such as robust decision-making or optimal reliable strategies may provide useful insights into the effects of these deep uncertainties and help guide the design of adaptive strategies.
Asthma attacks are a major global source of morbidity and cost. The incidence and impact of asthma attacks have not improved despite widespread adoption of effective universal treatment guidelines. Consequently, there is increasing interest in managing asthma based on specific assessments of both current symptoms and future risk. In this review, we consider 'risk' in asthma, and how it might be assessed from the patient's history and objective measurements. We also discuss the potential for encouraging shared decision-making and improving medical consensus through explicit communication of risk and highlight the potential opportunities and challenges in risk assessment to improve asthma management through individualised treatment strategies.

Since 1984 NASA has funded several major programs to develop Reliability/Risk Methods and tools for engineers to apply in the design and assessment of aerospace hardware. Two probabilistic software tools that show great promise for practical application are the finite element code NESSUS and the system risk analysis code QRAS. This paper examines NASA's past, present, and future directions in reliability and risk engineering applications, Both the NESSUS and QRAS software tools are detailed.
Prominent tools for assessing and managingrisk include risk cubes, risk burndown charts, and automated riskmanagement software. They are generally lacking, however, in accommodating ideation and brainstorming to identify potential problems. A suggested ...

Government agencies, including those responsible for transportation, are beginning to adopt the use of modern project management techniques which incorporate riskmanagement. In particular, for large transportation construction projects, quantitative riskmanagement is being utilized as an optimal process. Quantitative riskmanagement involves quantitative (i.e. probabilistic) risk assessment in addition to risk response. Probabilistic risk assessment of a project takes
The present study aims to show how various medical and nonmedical components contribute to success and failure in the management of colorectal cancer. The first encounter, subsequent diagnosis, and surgical therapy of a patient with Dukes B sigmoid cancer is modeled as a reliability block diagram with a serial and parallel arrangement of various components. The overall probability of a patient with new-onset colorectal cancer to visit a physician, be correctly diagnosed, and undergo successful therapy is 69%. The reduction in the overall success, despite the fact that the majority of components are assumed to function with failure rates of 5% or less, is a reflection of the multitude of serial subsystems involved in the management of the patient. In contrast, the parallel arrangement of subsystems results in a relative insensitivity of the overall system to failure, a greater stability, and an improved performance. Since no medical system functions perfectly, redundancy associated with parallel subsystems assures a better overall outcome. System analysis of health care provides a means to improve its performance. PMID:10063917

Biosecurity, biocontainment, and disease riskmanagement on dairy replacement operations are time- and labor-intensive, planned programs. Oftentimes the value of these programs is realized only after disease is introduced to a facility or a disease outbreak occurs. There is no "one-plan-fits-all;" each plan must be tailored to meet the needs of management's goals and expectations and problems specific to a production enterprise or geographic region. A standard framework applicable to biosecurity programs includes: (1) hazard identification, (2) exposure assessment, (3) risk characterization, and (4) riskmanagement. The discussion presented here helps lay the framework for development and implementation of biosecurity and risk-management programs within dairy replacement facilities. PMID:18299037

Background Riskmanagement is an important aspect of education for all residents. Unfortunately, few curricula currently exist to fulfill this educational need. Objective We developed a curriculum that teaches residents basic principles of riskmanagement with the goals of (1) educating residents about the medical-legal environment in which they operate, (2) helping residents identify common malpractice exposures, and (3) teaching practical riskmanagement/patient safety interventions that can be implemented in their practice that could reduce malpractice exposure and improve patient safety. Methods The curriculum was developed by Medical RiskManagement, LLC, a Connecticut-based riskmanagement firm, in conjunction with academic leadership at the University of Connecticut. The program uses 3 learning modalities: live lectures, web-based video modules, and e-mailed learning publications. Gains in resident knowledge through participation in the curriculum were measured using pretests and posttests. Learner satisfaction with the curriculum was measured through web-based surveys. Results We found a significant improvement in knowledge in residents who took the pretest and posttest (P < .001). Of the survey respondents, 97% said the content was relevant to their specialty practice and 95% responded that these sessions should be held annually. Most respondents indicated they would change their practice as a result of what they learned from the live lectures. Conclusion This riskmanagement curriculum has been successful in providing our residents with learning activities in riskmanagement, improving their knowledge of riskmanagement principles, and changing their attitudes and behaviors. These improvements may lead to fewer malpractice claims against them and the hospitals they train in.

Most occupational health and safety professionals understand the difference between “hazard” and “risk.” However, the distinction between these terms is not well understood in the electrical industry where the terms are often used interchangeably. This gap between these two groups of professionals needs to be bridged to ensure electrical hazards and the risks arising from those hazards are effectively addressed.
The paper discusses the overall process of system safety optimization in the space program environment and addresses in particular methods that enhance the efficiency of this activity. Effective system safety optimization is achieved by concentrating the available engineering and safety assurance resouces on the main risk contributors. The qualitative risk contributor identification by means of the hazard analyses and the FMECA constitute the basis for the system safety process. The risk contributors are ranked firstly on a qualitative basis according to the consequence severities. This ranking is then refined by mishap propagation/recovery time considerations and by probabilistic means (PRA). Finally, in order to broaden and extend the use of risk contributor ranking as a managerial tool in project resource assignment, quality, manufacturing and operations related critical characteristics, i.e. risk influencing factors, are identified for managerial visibility.
As an intern this summer in the GRC RiskManagement Office, I have become familiar with the NASA Continuous RiskManagement Process. In this process, risk is considered in terms of the probability that an undesired event will occur and the impact of the event, should it occur (ref., NASA-NPG: 7120.5). Riskmanagement belongs in every part of every project and should be ongoing from start to finish. Another key point is that a risk is not a problem until it has happened. With that in mind, there is a six step cycle for continuous riskmanagement that prevents risks from becoming problems. The steps are: identify, analyze, plan, track, control, and communicate & document. Incorporated in the first step are several methods to identify risks such as brainstorming and using lessons learned. Once a risk is identified, a risk statement is made on a risk information sheet consisting of a single condition and one or more consequences. There can also be a context section where the risk is explained in more detail. Additionally there are three main goals of analyzing a risk, which are evaluate, classify, and prioritize. Here is where a value is given to the attributes of a risk &e., probability, impact, and timeframe) based on a multi-level classification system (e.g., low, medium, high). It is important to keep in mind that the definitions of these levels are probably different for each project. Furthermore the risks can be combined into groups. Then, the risks are prioritized to see what risk is necessary to mitigate first. After the risks are analyzed, a plan is made to mitigate as many risks as feasible. Each risk should be assigned to someone in the project with knowledge in the area of the risk. Then the possible approaches to choose from are: research, accept, watch, or mitigate. Next, all risks, mitigated or not, are tracked either individually or in groups. As the plan is executed, risks are re-evaluated, and the attribute values are adjusted as necessary. Metrics are established and monitored as tools for risk tracking. Also a trigger or threshold should be set on the metric data that indicates when an action is needed. Results of this tracking are usually evaluated and reported in a relevant format at weekly or monthly meetings. Choosing controls is the subsequent step, which involves the effects of the tracking. The three basic controls are: close, continue tracking, and re- plan. Finally communicate & document is the last step, but occurs throughout the process. It is vital that main risks, plans, changes, and progress are known by everyone in the project. A good way to keep everyone updated and inform other projects of common issues is by thoroughly documenting project risks. NASA sees value in riskmanagement and believes that projects have greater probability or success by using the NASA Continuous RiskManagement Process.
Riskmanagement processes (RMPs) are logically consistent and structured approaches to enumerating and understanding potential risk factors and assessing consequences and uncertainties associated with these identified risk factors. Based on this information, we can evaluate and choose the best course of action in order to cope up with the identified risks and to achieve the desired objectives of a given
Various research undertaken over the past decade has improved our ability to assess and effectively manage contaminated sediments. Key to this improvement is a better understanding of the risks, both in time and space.

The National Compact Stellarator Experiment (NCSX) was designed to test physics principles of an innovative stellarator design developed by Princeton Plasma Physics Laboratory and Oak Ridge National Laboratory. Construction of some of the major components and subassemblies was completed, but the estimated cost and schedule for completing the project grew as the technical requirements and risks became better understood, leading to its cancellation in 2008. The project's risks stemmed from its technical challenges, primarily the complex component geometries and tight tolerances that were required. The initial baseline, which was established in 2004, was supported by a riskmanagement plan and risk-based contingencies, both of which proved to be inadequate. Technical successes were achieved in the construction of challenging components and subassemblies, but cost and schedule growth was experienced. As part of an effort to improve project performance, a new riskmanagement program was devised and implemented in 2007-2008. It led to a better understanding of project risks, a sounder basis for contingency estimates, and improved management tools. Although the risks were ultimately unacceptable to the sponsor, valuable lessons in riskmanagement were learned through the experiences with the NCSX project.

Business Process Management (BPM) is considered an essential strategy to create and maintain sustainable competitive advantage. While researchers are anxious to identify critical success factors for the management of business process related projects, the risks associated with these projects have received considerably less attention.

The two reliability models, their testing, and the modifications of a unified distribution planning model to calculate reliability indices are described. The historical reliability assessment model HISRAM is designed to suit most utilities. Four implementation levels with different input data requirements and output capabilities permit a utility to select a level appropriate to its needs. User-defined divisions, causes and output options further add to the program flexibility. A unique feature of HISRAM is the program generation of the appropriate outage reporting form following level selection and initialization. This allows the engineer to review data input requirements before field implementation. It has the capability of estimating component failure rates and restoration times upon provision of suitable input data. The predictive reliability assessment model PRAM uses continuity criteria, together with component failure rates and restoration times to calculate load point indices. System indices similar to those produced by HISRAM are also calculated. Varying degrees of detail for representing the protection system are available through three user-selected models. Both models were tested through application. The conclusions and recommendations of the entire project are included.

The major focus for continued development of the Numerical Evaluation of Stochastic Structures Under Stress (NESSUS) codes is in support of system testing and certification of advanced propulsion systems. Propulsion system testing has evolved over the years from tests designed to show success, to tests designed to reveal reliability issues before service use. Such test conditions as performance envelope corners, high rotor imbalance, power dwells, and overspeed tests are designed to shake out problems that can be associated with low and high cycle fatigue, creep, and stress rupture, bearing durability, and the like. Subsystem testing supports system certification by standing as an early evaluation of the same durability and reliability concerns as for the entire system. The NESSUS software system is being further developed to support the definition of rigorous subsystem and system test definition and reliability certification. The principal technical issues are outlined which are related to system reliability, including key technology issues such as failure mode synergism, sequential failure mechanisms, and fault tree definition.
The objective of this article is to provide an overview of the basis of risk analysis, assessment and management, accompanying problems and principles of riskmanagement when drafting an environmental geotechnical model, enabling the analysis of an entire territory or developed region as a whole. The environmental impact will remain within the limits of the criteria specified with the standards and will be acceptable for human health and environment. An essential part of the solution of the problem is the engineering-geological model based on risk analysis and the assessment and forecast of mutual effects of the processes.

The authors propose an approach to analyzing riskmanagement activities when multiple risks are bundled within a firm's assets or liabilities. They classify potentially bundled risks into two types: compensated risk and hedgeable risk. Firms earn rents for bearing compensated risk such as credit risk, and earn zero economic rents for bearing hedgeable risk such as interest rate risk. Because

The purpose of this qualitative study was to describe the process by which hospital staff nurses keep patients safe within their hospital safety culture. Findings from this study culminated in a grounded theory of ManagingRisk, the process by which nurses keep their patients safe from harm. Participants perceived that their patients were always at risk (it's always something), thus keeping patients safe was a continual, repetitive process of managingrisk to prevent harm to patients. Stages of this process included risk assessment, risk recognition, prioritization, and protective interventions. Practicing nurses can use this theory to understand and articulate their critical role in keeping patients safe in hospitals. Further examination of this process is necessary for targeted assessment of a safety culture's impact on bedside nursing practice, thus providing a basis for specific interventions to improve patient safety.

In this paper we set out to demonstrate that the traditional approach to riskmanagement is based on a flawed assumption regarding the objectivity of risk. Riskmanagement is generally seen as a possible remedy for the frequent failure of ISD efforts. The idea behind traditional riskmanagement is that risk factors must first be identified and evaluated, then eliminated
This article is concerned with the reliable H? output feedback control problem against actuator failures for a class of uncertain discrete time-delay systems with randomly occurred nonlinearities (RONs). The failures of actuators are quantified by a variable varying in a given interval. RONs are introduced to model a class of sector-like nonlinearities that occur in a probabilistic way according to
Riskmanagement is the systematic application of management policies, procedures, and practices to the tasks of analyzing, evaluating, controlling and monitoring risk (the effect of uncertainty on objectives). Clinical laboratories conduct a number of activities that could be considered riskmanagement including verification of performance of new tests, troubleshooting instrument problems and responding to physician complaints. Development of a quality control plan for a laboratory test requires a process map of the testing process with consideration for weak steps in the preanalytic, analytic and postanalytic phases of testing where there is an increased probability of errors. Control processes that either prevent or improve the detection of errors can be implemented at these weak points in the testing process to enhance the overall quality of the test result. This manuscript is based on a presentation at the 2nd International Symposium on Point of Care Testing held at King Faisal Specialist Hospital in Riyadh, Saudi Arabia on October 12-13, 2010. Riskmanagement principles will be reviewed and progress towards adopting a new Clinical and Laboratory Standards Institute Guideline for developing laboratory quality control plans based on riskmanagement will be discussed.

Traditionally toxicology was the science of poisons and antidotes. Because of societal and historical reasons, there developed a need to determine public hazard. This need has resulted in regulatory toxicology, the science of how to evaluate public health and environmental safety by evaluating the possibility of hazard or injury from the use of a substance to humans under practical conditions of use and exposure. The intense investigation, especially in this century, made to address these concerns has led to a significant broadening of the knowledge base in toxicology and to a new capacity to alter toxicity. How the risk of a toxic endpoint is assessed and the steps taken to assure safety are part of a process termed riskmanagement. Managingrisks can affect society, public health, employment, and international economics. It therefore includes, in addition to information on toxicity, many other factors such as values, politics, and economics. In order to provide a description of how risks are managed in a society such as the United States, some background about why certain risks are of concern is given, and how this concern is manifest and the methods of managingrisk with an emphasis on regulatory toxicology are discussed.

"Space Weather" is defined as electromagnetic and particle conditions in the space environment that can disturb space-borne and ground-based technological systems (e.g. satellite operation, telecommunication, aviation, electric power transmission) and even endanger human health. Thus, space weather is of great importance to the society since people are dependent on reliable operation of modern technology, interruptions of which may lead to large economical and other losses. Physical processes involved in space weather constitute a complicated chain from the Sun to the Earth's surface. Thus, a full understanding of space weather and the risks it produces requires expertise in many different disciplines of science and technology. Space weather is a new subject among the natural risks and hazards which threaten the society and its infrastructure (although the first observations of ground effects of space weather were already made about 150 years ago). Monitoring systems for the management of other risks, such as floods, forest fires, etc., and for security are, to a great extent, based on satellite observations. Spacecraft and the communication between satellites and the ground are vulnerable to space weather. Thus, besides being a direct risk to technological systems, space weather may also be indirectly adverse to riskmanagement. These two aspects of space weather are considered in a proposal to be submitted to EU's Sixth Framework Programme under the "Aeronautics and Space" priority in the "Global Monitoring for Environment and Security (GMES) / RiskManagement" area in March 2004. The proposal coordinated by the Finnish Meteorological Institute with five to ten participating institutes is called SW-RISK ("Space Weather - Risk Indices from Scientific Know-how").

The United States Food and Drug Administration (FDA) has the primary regulatory responsibility to ensure that medications are safe and effective both prior to drug approval and while the medication is being actively marketed by manufacturers. The responsibility for safe medications prior to marketing was signed into law in 1938 under the Federal Food, Drug, and Cosmetic Act; however, a significant riskmanagement evolution has taken place since 1938. Additional federal rules, entitled the Food and Drug Administration Amendments Act, were established in 2007 and extended the government's oversight through the addition of a Risk Evaluation and Mitigation Strategy (REMS) for certain drugs. REMS is a mandated strategy to manage a known or potentially serious risk associated with a medication or biological product. Reasons for this extension of oversight were driven primarily by the FDA's movement to ensure that patients and providers are better informed of drug therapies and their specific benefits and risks prior to initiation. This article provides an historical perspective of the evolution of medication riskmanagement policy and includes a review of REMS programs, an assessment of the positive and negative aspects of REMS, and provides suggestions for planning and measuring outcomes. In particular, this publication presents an overview of the evolution of the REMS program and its implications. PMID:23113627

The Integrated Reliability and Risk Analysis System (IRRAS) is a state-of-the-art, microcomputer-based probabilistic risk assessment (PRA) model development and analysis tool to address key nuclear plant safety issues. IRRAS is an integrated software tool that gives the user the ability to create and analyze fault trees and accident sequences using a microcomputer. This program provides functions that range from graphical fault tree construction to cut set generation and quantification. Also provided in the system is an integrated full-screen editor for use when interfacing with remote mainframe computer systems. Version 1.0 of the IRRAS program was released in February of 1987. Since that time, many user comments and enhancements have been incorporated into the program providing a much more powerful and user-friendly system. This version has been designated IRRAS 2.0 and is the subject of this user's guide. Version 2.0 of IRRAS provides all of the same capabilities as Version 1.0 and adds a relational data base facility for managing the data, improved functionality, and improved algorithm performance. 9 refs., 292 figs., 4 tabs.

Understanding the impact of water quality on the health of a general population is challenging due high degrees of uncertainty and variability in hydrological, toxicological and human aspects of the system. Assessment of the impact of changes in water quality of a public water supply is critical to management of that water supply. We propose the use of three different system evaluation criteria: Reliability, Resilience and Vulnerability (RRV) as a tool for assessing the impact of uncertainty in the arrival of contaminant mass through time with respect to human health risks on a variable population. These criteria were first introduced to the water resources community by Hashimoto et al (1982). Most simply one can understand these criteria as the following: Reliability is the likelihood of the system being in a state of success; Resilience is the probability that the system will return to a state of success at t+1 if it is in failure at time step t, and Vulnerability is the severity of failure, which here is defined as the maximum health risk. These concepts are applied to a theoretical example where the water quality at a water supply well varies over time: health impact is considered based on sliding, 30-year windows of exposure to water derived from the well. We apply the methodology, in terms of uncertainty in water quality deviations, to eight simulated breakthrough curves of a contaminant at the well: each curve represents equal mass of contaminant arriving at the well over a 70-year lifetime of the well, but different mass distributions over time. These curves are used to investigate the impact of uncertainty in the distribution through time of the contaminant mass at the well, as well as the initial arrival of the contaminant over the 70-year lifetime of the well. In addition to extending the health risk through time with uncertainty in mass distribution, we incorporate variability in the human population to examine the evolution of the three criteria within the population. We show that the distribution of predicted health risk, as measured by each of the RRV criteria, is strongly dependent on both the distribution (over time) of the arrival of contaminant mass at the well and the timing of the initial arrival of contaminant within the 70 year lifetime of the well.
HRA is a method used to describe, qualitatively and quantitatively, the occurrence of human failures in the operation of complex systems that affect availability and reliability. Modeling human actions with their corresponding failure in a PRA (Probabilistic Risk Assessment) provides a more complete picture of the risk and risk contributions. A high quality HRA can provide valuable information on potential areas for improvement, including training, procedural, equipment design and need for automation.
In this context there are many possible assurance activities. Some focus on the prevention of defects - for example, up-front planning, adoption of design standards, configuration management, training, etc. Others focus on the detection of defects - either to detect latent defects in a system (and so be able to correct them before actual deployment of the system), or to increase confidence that such defects are not present. For example, a wide gamut of reviews, design walkthroughs, tests, inspections, analyses, etc. can be applied to systems and their components.

The aim of this paper is to introduce a new framework for operational riskmanagement, based on Bayesian Markov chain Monte Carlo (MCMC). Under the LDA approach, non-conjugate distribution is used to fit the frequency and severity. One of the problems relative to the non-conjugate distribution is difficult to estimate the parameter. Then the Bayesian MCMC approach is brought forward.
Software projects are often faced with unanticipated problems caused by e.g. changes in the development environment resulting in delays or threatening the ability of the project to succeed. Managing these uncertainties is a challenging task at all phases of the development, but nevertheless crucial in controlling schedule and costs. Therefore software development risks need to be controlled as early as
Ever since the financial crisis of the banking system of 2008 - 2010 the paradigm that deposits or other exposures towards major banks are safe has been fundamentally questioned.

A griculture is an inherently risky economic activity. A large array of uncontrollable elements can affect output production and prices, resulting in highly variable economic returns to farm households. In developing countries, farmers also lack access to both modern instruments of riskmanagement—such as agricultural insurance, futures contracts, or guarantee funds—and ex post emergency government assistance. Such farmers rely on

Risk analysis of key systems have become a growing topic late of because of the development of offshore structures. Equipment failures of offloading system and fire accidents were analyzed based on the floating production, storage and offloading (FPSO) features. Fault tree analysis (FTA), and failure modes and effects analysis (FMEA) methods were examined based on information already researched on modules of relex reliability studio (RRS). Equipment failures were also analyzed qualitatively by establishing a fault tree and Boolean structure function based on the shortage of failure cases, statistical data, and risk control measures examined. Failure modes of fire accident were classified according to the different areas of fire occurrences during the FMEA process, using risk priority number (RPN) methods to evaluate their severity rank. The qualitative analysis of FTA gave the basic insight of forming the failure modes of FPSO offloading, and the fire FMEA gave the priorities and suggested processes. The research has practical importance for the security analysis problems of FPSO.
Warning System and emergency plans are two fundamental elements of riskmanagement and governance, but unfortunately, most of the times, they are developed independently one from the other, as sequential steps not necessary linked. The main goal of this research is to develop a methodology for applying Early Warning Systems - Community Based to the emergency plan using the results of social surveys and quantitative risk assessment, taking into account the administrative structure and the planning system of the study area, as well as the legislative obligations of each entity involved in the risk governance and emergency management. Using a integrative scientific and social approach to natural hazards the research aim to contribute to fill the gap between scientists, policy makers, stakeholders and community. Initially applied in Comunità Montana Valtellina di Tirano, Italy, the methodology involves the application of two comprehensive surveys. The first is addressed to stakeholders (including policy makers, emergency managers, emergency volunteers, consultants and scientists) in order to determine their needs, points of view, concerns and constraints. The second survey is addressed specifically to local community to assess risk perception, awareness, needs, capacity and level of trust towards stakeholders, besides asking for their willingness to participate in future risk communication activities. The Early Warning System developed includes all the stages of the early warning process (hazard evaluation and forecasting; warning and dissemination and public response) and would be based on a multidisciplinary partnership that takes into account the different actors involved in the riskmanagement in order to accomplish a more reliable and credible result, including an emergency plan specifically designed for each study area. After evaluating the results of the surveys, information and education campaigns will be developed with the objective of reducing vulnerability of the population by increasing risk perception and improving response to early warnings. Spatial planning and specifically decisions about future land-use are critical to mitigate the hazard and to reduce the vulnerability, therefore some inputs will be provided to the decision-makers on where additional risk identification, risk reduction and risk transfer measures are especially necessary.

Bipolar disorders are prevalent, often severe, and disabling illnesses with elevated lethality largely due to suicide. Suicide rates average approximately 1% annually, or perhaps 60 times higher than the international population rate of 0.015% annually. Suicidal acts typically occur early in bipolar disorders and in association with severe depressive or mixed states. The high lethality of suicidal acts in bipolar disorders is suggested by a much lower ratio of attempts:suicide (approximately 3:1) than in the general population (approximately 30:1). Risk factors can help to identify patients at increased suicidal risk, but ongoing clinical assessment is essential to limit risk. Empirical short-term interventions to manage acute suicidal risk include close clinical supervision, rapid hospitalization, and electroconvulsive therapy. Remarkably, however, evidence of the long-term effectiveness of most treatments against suicidal behavior is rare. A notable exception is lithium prophylaxis, which is associated with consistent evidence of major (approximately 80%), sustained relative reductions of risk of suicides and attempts, and lower lethality (increased attempts:suicide ratio). Such benefits are unproved for other treatments commonly used to treat bipolar disorder patients, including anticonvulsants, antipsychotics, antidepressants, and psychosocial interventions. Applying available knowledge systematically, with close and sustained clinical supervision, can enhance management of suicidal risk in bipolar disorders patients. PMID:16816785

The field interrater reliability of three assessment tools frequently used by mental health professionals when evaluating sex offenders' risk for reoffending--the Psychopathy Checklist-Revised (PCL-R), the Minnesota Sex Offender Screening Tool-Revised (MnSOST-R) and the Static-99-was examined within the context of sexually violent predator program proceedings. Rater agreement was highest for the Static--99 (intraclass correlation coefficient [ICC?] = .78) and lowest for the PCL-R (ICC? = .60; MnSOST-R ICC? = .74), although all instruments demonstrated lower field reliability than that reported in their test manuals. Findings raise concerns about the reliability of risk assessment tools that are used to inform judgments of risk in high-stake sexually violent predator proceedings. Implications for future research and suggestions for improving evaluator training to increase accuracy when informing legal decision making are discussed. PMID:22563984

Acute pulmonary embolism (PE) poses a significant burden on health and survival. Its severity ranges from asymptomatic, incidentally discovered subsegmental thrombi to massive, pressor-dependent PE complicated by cardiogenic shock and multisystem organ failure. Rapid and accurate risk stratification is therefore of paramount importance to ensure the highest quality of care. This article critically reviews currently available and emerging tools for risk-stratifying acute PE, and particularly for distinguishing between elevated (intermediate) and low risk among normotensive patients. We focus on the potential value of risk assessment strategies for optimizing severity-adjusted management. Apart from reviewing the current evidence on advanced early therapy of acute PE (thrombolysis, surgery, catheter interventions, vena cava filters), we discuss recent advances in oral anticoagulation with vitamin K antagonists, and with new direct inhibitors of factor Xa and thrombin, which may contribute to profound changes in the treatment and secondary prophylaxis of venous thrombo-embolism in the near future.

Various research undertaken over the past decade has improved our ability to assess and effectively manage contaminated sediments. Key to this improvement is a better understanding of the risks, both in time and space. Sediments can pose risks if contaminants are present in the biologically active zone of a water body or if transport processes can move contaminants into that zone. Conversely, effective management of contaminants can be accomplished by physically separating contaminants from the biologically active zone or hindering the transport processes that can result in contaminant migration. Both of these are accomplished by sediment capping, either conventional capping with a passive barrier such as sand, or, when greater control over mobile contaminants is required, by active capping in which amendments are used to retard any applicable transport processes. In this paper, the key transport and exposure processes are assessed and the ability to manage these risks with both passive and active capping evaluated. In summary, conventional sand capping can be effective in reducing exposures, while active capping can provide greater control; options include activated carbon/coke (to sequester organic compounds), organo-clays (to control nonaqueous phase and dissolved liquids), and clay polymers (to control permeability). Field demonstrations are underway on both coasts (including Portland, Oregon, and the Anacostia) to assess the effectiveness of various in-situ options, including organo-clay mats and other active caps. In addition, a unique in-situ sampling approach is demonstrating that pore water concentrations can be determined and employed to assess baseline or post-remedial risks due to contaminated sediments. Additional capping research is addressing issues such as gas release, treatment for other contaminants, and geotechnical tests to evaluate mobility of nonaqueous phase liquids due to cap loading and consolidation. Science and technology are combining to support more realistic risk assessments and practical management measures for contaminated sediments, with particular emphasis on in situ approaches. (authors)

Starting with an overview on losses due to mountain hazards in the Russian Federation and the European Alps the question is raised why a substantial number of events still is recorded - despite considerable efforts in hazard mitigation and risk reduction. The main reason for this paradox lies in a missing dynamic risk-based approach, and it is shown that these dynamics have different roots: Firstly, neglecting climate change and systems dynamics, the development of hazard scenarios is based on the static approach of design events. Secondly, due to economic development and population dynamics, the elements at risk exposed are subject to spatial and temporal changes. These issues are discussed with respect to temporal and spatial demands. As a result, it is shown how risk is dynamic on a long-term and short term scale, which has to be acknowledged in the risk concept if this concept is targeted at a sustainable development of mountain regions. A conceptual model is presented that can be used for dynamical risk assessment, and it is shown by different management strategies how this model may be converted into practice. Furthermore, the interconnectedness and interaction between hazard and risk are addressed in order to enhance prevention, the level of protection and the degree of preparedness.

Spaceflight exposes astronauts to a host of environmental factors which could increase their risk for cancer. Epidemiological studies have shown an increased incidence of breast cancer in female commercial flight attendants, with occupational risk factors as one of the proposed mechanisms for the higher incidence in this cohort. Since female astronauts are exposed to similar occupational conditions as flight attendants, they too may be at an increased risk for breast cancer. With the planning of exploration class missions to the Moon and to Mars it is important to assess and minimize the risk for breast malignancy, and to have a well-defined protocol for the diagnosis and treatment of a breast mass discovered during a mission. Risk factors for development of breast cancer in the female astronaut include ionizing radiation, disrupted melatonin homeostasis secondary to circadian shifting, chemical exposure, and changes in immune function. Preflight, in-flight, and postflight screening and management modalities include imaging and fine needle aspiration (FNA). Employing such a strategy may provide a viable management approach in the case of a newly diagnosed breast mass inflight. PMID:17511296

NASA Headquarters Environmental Management Division supports NASA's mission to pioneer the future in space exploration, scientific discovery, and aeronautics research by integrating environmental considerations into programs and projects early-on, thereby proactively reducing NASA's exposure to institutional, programmatic and operational risk. As part of this effort, NASA established the Principal Center for Regulatory Risk Analysis and Communication (RRAC PC) as a resource for detecting, analyzing, and communicating environmental regulatory risks to the NASA stakeholder community. The RRAC PC focuses on detecting emerging environmental regulations and other operational change drivers that may pose risks to NASA programs and facilities, and effectively communicating the potential risks. For example, regulatory change may restrict how and where certain activities or operations may be conducted. Regulatory change can also directly affect the ability to use certain materials by mandating a production phase-out or restricting usage applications of certain materials. Regulatory change can result in significant adverse impacts to NASA programs and facilities due to NASA's stringent performance requirements for materials and components related to human-rated space vehicles. Even if a regulation does not directly affect NASA operations, U.S. and international regulations can pose program risks indirectly through requirements levied on manufacturers and vendors of components and materials. For example, manufacturers can change their formulations to comply with new regulatory requirements. Such changes can require time-consuming and costly requalification certification for use in human spaceflight programs. The RRAC PC has implemented a system for proactively managing regulatory change to minimize potential adverse impacts to NASA programs and facilities. This presentation highlights the process utilized by the RRACPC to communicate regulatory change and the associated potential risks within NASA, as well as the process for communicating and cooperating with other government agencies and industry partners, both domestic and international, to ensure mission success.

Engineering Test Satellite - 8 (ETS-8) is the Japanese largest geo-synchronous satellite of 3 tons in mass, of which mission is mobile communications and navigation experiment. It is now in the flight model manufacturing phase. This paper introduces the riskmanagement taken in this project as a reference. The mission success criteria of ETS-8 are described at first. All the riskmanagement activities are planned taking these criteria into consideration. ETS-8 consists of many new technologies such as the large deployable antenna (19m x 17m), 64-bit MPU, 100 V solar paddle and so on. We have to pay attention to control these risk through each phase of development. In system design of ETS - 8, almost components have redundancy and there is some back-up function to avoid fatal failure. What kind of back-up function should be taken is one of the hot issues in this project. The consideration process is described as an actual case. In addition to conventional riskmanagement procedure, FMEA and identification of the critical items so on, we conducted the validation experiment in space by use of a scale model that was launched on Ariane 5. The decision to conduct this kind of experiment is taken after evaluation between risk and cost, because it takes a lot of resources of project. The effect of this experiment is also presented. Failure detection, isolation and reconfiguration in the flight software are more important as the satellite system becomes large and complicated. We did the independent verification and validation to the software. Some remarks are noted with respect to its effectiveness.
A field trial was conducted to evaluate the reliability of four widely used health risk appraisals (HRAs). A total of 338 randomly selected adults aged 25 to 65 years residing in the Boston metropolitan area completed an HRA on two occasions seven to 12 weeks apart. Test-retest reliability was assessed by comparing self-reported baseline risk scores to follow-up scores for heart attack risk and selected coronary heart disease risk factors. Respondents generally gave consistent reports for family history, cigarette smoking, and relative weight (test-retest r greater than .75), but self-reported scores for physiologic status (blood pressure and cholesterol) and lifestyle (diet, physical activity, and stress) were much less stable. Coefficients for heart attack risk and appraised age ranged from .43 to .87 for the four HRAs. The reliabilities of two self-scored instruments were greatly reduced by mathematical errors made by respondents when computing their heart attack risk scores. These results were not affected by the length of the follow-up period (seven to 12 weeks). PMID:2817186

The ecological risk assessment process in its ideal form is an unbiased approach for assessing the probability of harm to the environment as a consequence of a given action. This information can then be combined with other societal values and biases in the management of such risks. However, as the process currently is understood, decision makers often are accused of manipulating information in order to generate decisions or achieve buy in from the public in support of a particular political agenda. A clear understanding of the nature of the riskmanagement process can help define areas where information should be free from social or personal bias, and areas where values and judgments are critical. The authors do not propose to discuss the individual`s decision-making process, but rather to address the social process of risk communication and environmentally-related decision-making, identifying which parts of that process require bias-free, scientifically generated information about the consequences of various actions and which parts need an understanding of the social values which underlie the informed choices among those possible actions.

System reliability depends on the reliability of the system's components and the structure of the system. For example, in a competing risks model, the system fails when the weakest component fails. The reliability function and the quantile function of a complicated system are two important metrics for characterizing the system's reliability. When there are data available at the component level, the system reliability can be estimated by using the component level information. Confidence intervals (CIs) are needed to quantify the statistical uncertainty in the estimation. Obtaining system reliability CI procedures with good properties is not straightforward, especially when the system structure is complicated. In this paper, we develop a general procedure for constructing a CI for the system failure-time quantile function by using the implicit delta method. We also develop general procedures for constructing a CI for the cumulative distribution function (cdf) of the system. We show that the recommended procedures are asymptotically valid and have good statistical properties. We conduct simulations to study the finite-sample coverage properties of the proposed procedures and compare them with existing procedures. We apply the proposed procedures to three applications; two applications in competing risks models and an application with a k-out-of-s system. The paper concludes with some discussion and an outline of areas for future research. PMID:23381812

Operational Riskmanagement, the least covered component of Enterprise Wide RiskManagement, needs intelligent tools to implement Comprehensive Emergency Management Programs. In this paper we discuss how an Intelligent Decision Support System (I-DSS), based on Fuzzy Logic, can be used for supporting the management of complex and critical systems, especially under contingency situations, with limited resources' availability. This I-DSS is

As an advanced management mode, the construction supply chain management is playing an increasingly important role in the fierce market competition. Construction supply chain management can not only increase the construction enterprises' profits, improve the core competitiveness, but also bring some risks. If we can not correctly identify, analyze and management these risks, the enterprises will suffer serious economic losses.
Incident data about disruptions to the electric power grid provide useful information that can be used as inputs into riskmanagement policies in the energy sector for disruptions from a variety of origins, including terrorist attacks. This article uses data from the Disturbance Analysis Working Group (DAWG) database, which is maintained by the North American Electric Reliability Council (NERC), to look at incidents over time in the United States and Canada for the period 1990-2004. Negative binomial regression, logistic regression, and weighted least squares regression are used to gain a better understanding of how these disturbances varied over time and by season during this period, and to analyze how characteristics such as number of customers lost and outage duration are related to different characteristics of the outages. The results of the models can be used as inputs to construct various scenarios to estimate potential outcomes of electric power outages, encompassing the risks, consequences, and costs of such outages.

Experts contend that weather and climate forecasts could have an important role in riskmanagement strategies for community water systems. Yet, most water managers make minimal use of these forecasts. This research explores the determinants of the use of weather and climate forecasts by surveying managers of community water systems in two eastern American states (South Carolina and the Susquehanna River Basin of Pennsylvania). Assessments of the reliability of weather and climate forecasts are not driving their use as water managers who find forecasts reliable are no more likely to use them than are managers who find them unreliable. Although larger systems and those depending on surface water are more likely to use forecasts for some (but not all) purposes, the strongest determinant of forecast use is risk perceptions. Water managers who expect to face problems from weather events in the next decade are much more likely to use forecasts than are water managers who expect few problems. Their expectations of future problems are closely linked with past experience: water managers who have had problems with specific types of weather events (e.g., flood emergencies) in the last 5 years are likely to expect to experience problems in the next decade. Feeling at risk, regardless of the specific source of that weather-related risk, stimulates a decision to use weather and climate forecasts. PMID:16297230
This study describes the development of the WAVR-21, a structured professional judgment guide for the assessment of workplace targeted violence, and presents initial interrater reliability results. The 21-item instrument codes both static and dynamic risk factors and change, if any, over time. Five critical items or red flag indicators assess violent motives, ideation, intent, weapons skill, and pre-attack planning. Additional items assess the contribution of mental disorder, negative personality factors, situational factors, and a protective factor. Eleven raters each rated 12 randomly assigned cases from actual files of workplace threat scenarios. Summary interrater reliability correlation coefficients (ICCs) for overall presence of risk factors, risk of violence, and seriousness of the violent act were in the fair to good range, similar to other structured professional judgment instruments. A subgroup of psychologists who were coders produced an ICC of 0.76 for overall presence of risk factors. Some of the individual items had poor reliability for both clinical and statistical reasons. The WAVR-21 appears to improve the structuring and organizing of empirically based risk-relevant data and may enhance communication and decision making. PMID:23865721
The main cause of commanding errors is often (but not always) due to procedures. Either lack of maturity in the processes, incompleteness of requirements or lack of compliance to these procedures. Other causes of commanding errors include lack of understanding of system states, inadequate communication, and making hasty changes in standard procedures in response to an unexpected event. In general, it's important to look at the big picture prior to making corrective actions. In the case of errors traced back to procedures, considering the reliability of the process as a metric during its' design may help to reduce risk. This metric is obtained by using data from Nuclear Industry regarding human reliability. A structured method for the collection of anomaly data will help the operator think systematically about the anomaly and facilitate riskmanagement. Formal models can be used for risk based design and riskmanagement. A generic set of models can be customized for a broad range of missions.
Public health studies have shown that sleepiness at the wheel and other risks associated with sleep are responsible for 5% to 30% of road accidents, depending on the type of driver and/or road. In industrialized countries one-fifth of all traffic accidents can be ascribed to sleepiness behind the wheel. Sleep disorders and various common acute and chronic medical conditions together with lifestyles, extended work hours and prolonged wakefulness directly or indirectly affect the quality and quantity of one's sleep increasing the number of workers with sleep debt and staggered hours. These conditions may increase the risk of road accidents. Strategies to reduce this risk of both commercial and non-commercial drivers related to sleepiness include reliable diagnosis and treatment of sleep disorders, management of chronobiological conflicts, adequate catch-up sleep, and countermeasures against sleepiness at the wheel. Road transport safety requires the adoption of occupational health measures, including risk assessment, health education, technical-environmental prevention and health surveillance. PMID:23405652
We present ACES, an automated server provisioning system that aims to meet workload demand while minimizing energy consumption in data centers. To perform energy-aware server provisioning, ACES faces three key tradeoffs between cost, performance, and reliability: (1) maximizing energy savings vs. minimizing unmet load demand, (2) managing low power draw vs. high transition latencies for multiple power management schemes, and
An efficient, fuzzy expert system architecture is developed and presented, which is suitable for landfill operation reliabilitymanagement.

A distributed database management system (DDBMS) manages a collection of data stored at various processing nodes of a computer network. Global queries are processed by DDBMS, and tasks (join operations in these queries) are assigned to various nodes in the network. Optimal allocation of these tasks are discussed, with reliability as the objective function and communication-cost as the constraint function.
Quantified risk assessment (QRA) needs mathematicization of risk theory. However, attention has been paid almost exclusively to applications of assessment methods, which has led to neglect of research into fundamental theories, such as the relationships among risk, safety, danger, and so on. In order to solve this problem, as a first step, fundamental theoretical relationships about risk and riskmanagement were analyzed for this paper in the light of mathematics, and then illustrated with some charts. Second, man-machine-environment-management (MMEM) theory was introduced into risk theory to analyze some properties of risk. On the basis of this, a three-dimensional model of riskmanagement was established that includes: a goal dimension; a management dimension; an operation dimension. This goal management operation (GMO) model was explained and then emphasis was laid on the discussion of the risk flowchart (operation dimension), which lays the groundwork for further study of riskmanagement and qualitative and quantitative assessment. Next, the relationship between Formal Safety Assessment (FSA) and RiskManagement was researched. This revealed that the FSA method, which the international maritime organization (IMO) is actively spreading, comes from RiskManagement theory. Finally, conclusion were made about how to apply this riskmanagement method to concrete fields efficiently and conveniently, as well as areas where further research is required.
A methodology is described that enables to use safety management audit assessments and safety culture questionnaire results for estimating the reductions in the reliability of safety barriers in major hazard plants. The critical issue is the establishment of weight factors in combination with the anchoring of "good" safety management. A method is proposed to derive weight factors from statistical accident analysis in combination with a statistical analysis of safety management assessments at a representative sample of major hazard industries. A preliminary set of weight factors is presented with some examples of resulting reductions in reliability--this demonstration confirms that the set of weight factors needs further development.

This paper presents an overview of some of the research projects, conducted for the US Nuclear Regulatory Commission (NRC) that deal with the question: How can an acceptable level of risk of a nuclear power plant be maintained throughout its design life. With a viewpoint that life extension planning for a plant can be viewed as a long-range, strategic maintenance program, the products of this research are discussed from the perspective of being elements that can tie day-to-day, plant operational tactical decisions on component/system reliability with long-range strategic maintenance goals. A common factor in addressing issues associated with design life and life extension is the issue of component aging and the reliability implications of aging. A time-dependent reliability model is described which contains some of the requisite ingredients and is built on a framework from which the component aging/component reliability issue can be addressed. By way of select examples, the additional work needed to further address plant lifetime reliability and risk is indicated.
The construction industry is plagued by risk, and poor performance has often been the result. Although riskmanagement techniques have been applied, the lack of a formalised approach has produced inconsistent results. In this paper, a hierarchical risk breakdown structure is described to represent a formal model for qualitative risk assessment. The relationships between risk factors, risks, and their consequences
This paper discusses the U.S. Nuclear Regulatory Commission’s (NRC) activities to further the Proactive Management of Materials Degradation (PMMD), including those to determine the effectiveness of emerging NDE techniques. The paper discusses the first part of the development of a methodology to determine the effectiveness of these emerging NDE techniques for managing metallic degradation. This methodology draws on experience derived from evaluating techniques that have ‘emerged’ in the past. The methodology will follow five stages: a definition of inspection parameters, a technical evaluation, laboratory testing, round-robin testing, and the design of a performance demonstration program. This methodology will document the path taken for previous techniques and set a standardized course for future NDE techniques.

Frequency of radioactive release through ALS was also estimated. The
In support of a national need to improve the current state-of-the-art in alerting decision makers to the risk of terrorist attack, a quantitative approach employing scientific and engineering concepts to develop a threat-risk index was undertaken at the Idaho National Engineering and Environmental Laboratory (INEEL). As a result of this effort, a set of models has been successfully integrated into a single comprehensive model known as Quantitative Threat-Risk Index Model (QTRIM), with the capability of computing a quantitative threat-risk index on a system level, as well as for the major components of the system. Such a threat-risk index could provide a quantitative variant or basis for either prioritizing security upgrades or updating the current qualitative national color-coded terrorist threat alert.
In connection with the construction of four major liquefied natural gas (LNG) facilities in New York City, the New York City Fire Commissioner has asked NASA for assistance. It was decided that the Kennedy Space Center should develop a riskmanagement system (RMS) for the use of the New York Fire Department (NYFD). The RMS provides for a published set of safety regulations by the NYFD. A description of the RMS is presented as an example of an application of aerospace technology to a civilian sector, namely LNG facilities.
Electric power systems are experiencing dramatic changes with respect to structure, operation and regulation and are facing increasing pressure due to environmental and societal constraints. Bulk electric system reliability is an important consideration in power system planning, design and operation particularly in the new competitive environment. A wide range of methods have been developed to perform bulk electric system reliability evaluation. Theoretically, sequential Monte Carlo simulation can include all aspects and contingencies in a power system and can be used to produce an informative set of reliability indices. It has become a practical and viable tool for large system reliability assessment technique due to the development of computing power and is used in the studies described in this thesis. The well-being approach used in this research provides the opportunity to integrate an accepted deterministic criterion into a probabilistic framework. This research work includes the investigation of important factors that impact bulk electric system adequacy evaluation and security constrained adequacy assessment using the well-being analysis framework. Load forecast uncertainty is an important consideration in an electrical power system. This research includes load forecast uncertainty considerations in bulk electric system reliability assessment and the effects on system, load point and well-being indices and reliability index probability distributions are examined. There has been increasing worldwide interest in the utilization of wind power as a renewable energy source over the last two decades due to enhanced public awareness of the environment. Increasing penetration of wind power has significant impacts on power system reliability, and security analyses become more uncertain due to the unpredictable nature of wind power. The effects of wind power additions in generating and bulk electric system reliability assessment considering site wind speed correlations and the interactive effects of wind power and load forecast uncertainty on system reliability are examined. The concept of the security cost associated with operating in the marginal state in the well-being framework is incorporated in the economic analyses associated with system expansion planning including wind power and load forecast uncertainty. Overall reliability cost/worth analyses including security cost concepts are applied to select an optimal wind power injection strategy in a bulk electric system. The effects of the various demand side management measures on system reliability are illustrated using the system, load point, and well-being indices, and the reliability index probability distributions. The reliability effects of demand side management procedures in a bulk electric system including wind power and load forecast uncertainty considerations are also investigated. The system reliability effects due to specific demand side management programs are quantified and examined in terms of their reliability benefits.
Merapi (Central Java Province) and Bromo (East Java Province) volcanoes have human-environmental systems with unique characteristics, thus causing specific consequences on their riskmanagement. Various efforts have been carried out by many parties (institutional government, scientists, and non-governmental organizations) to reduce the risk in these areas. However, it is likely that most of the actions have been done for temporary and partial purposes, leading to overlapping work and finally to a non-integrated scheme of volcanic riskmanagement. This study, therefore, aims to identify and evaluate actions of risk and disaster reduction in Merapi and Bromo Volcanoes. To achieve this aims, a thorough literature review was carried out to identify earlier studies in both areas. Afterward, the basic concept of riskmanagement cycle, consisting of risk assessment, risk reduction, event management and regeneration, is used to map those earlier studies and already implemented riskmanagement actions in Merapi and Bromo. The results show that risk studies in Merapi have been developed predominantly on physical aspects of volcanic eruptions, i.e. models of lahar flows, hazard maps as well as other geophysical modeling. Furthermore, after the 2006 eruption of Merapi, research such on risk communication, social vulnerability, cultural vulnerability have appeared on the social side of riskmanagement research. Apart from that, disaster riskmanagement activities in the Bromo area were emphasizing on physical process and historical religious aspects. This overview of both study areas provides information on how risk studies have been used for managing the volcano disaster. This result confirms that most of earlier studies emphasize on the risk assessment and only few of them consider the risk reduction phase. Further investigation in this field work in the near future will accomplish the findings and contribute to formulate integrated volcanic riskmanagement cycles for both Merapi and Bromo.

Several key strategies can be used to manage the risk associated with innovation to create maximum value. These include balancing the timing of investments versus cash flows, management of fads, prioritization across the company, savvy portfolio management, and a system of metrics that measure real success. Successful R&D managers will do whatever is necessary to manage the risks associated with an R&D program and stick to their long-term strategy. PMID:22432615
Starting from the general concept of risk, we set up an economic analysis framework for Disaster RiskManagement (DRM) investment. It builds on uncertainty management techniques - notably Monte Carlo simulations - and includes both a risk and performance metrics adapted to recurring issues in disaster riskmanagement as entertained by governments and international organisations. This type of framework proves to be enlightening in several regards, and is thought to ease the promotion of DRM projects as "investments" rather than "costs to be born" and allow for meaningful comparison between DRM and other sectors. We then look at the specificities of disaster risk investments of medium to large scales through this framework, where some "invariants" can be identified, notably: (i) it makes more sense to perform analysis over long-term horizons -space and time scales are somewhat linked; (ii) profiling of the fluctuations of the gains and losses of DRM investments over long periods requires the ability to handle possibly highly volatile variables; (iii) complexity increases with the scale which results in a higher sensitivity of the analytic framework on the results; (iv) as the perimeter of analysis (time, theme and space-wise) is widened, intrinsic parameters of the project tend to weight lighter. This puts DRM in a very different perspective from traditional modelling, which usually builds on more intrinsic features of the disaster as it relates to the scientific knowledge about hazard(s). As models hardly accommodate for such complexity or "data entropy" (they require highly structured inputs), there is a need for a complementary approach to understand risk at global scale. The proposed framework suggests opting for flexible ad hoc modelling of specific issues consistent with one's objective, risk and performance metrics. Such tailored solutions are strongly context-dependant (time and budget, sensitivity of the studied variable in the economic framework) and can range from simple elicitation of data from a subject matter expert to calibrate a probability distribution to more advanced stochastic modelling. This approach can be referred to more as a proficiency in the language of uncertainty rather than modelling per se in the sense that it allows for greater flexibility to adapt a given context. In a real decision making context, one seldom has neither time nor budget resources to investigate all of these variables thoroughly, hence the importance of being able to prioritize the level of effort among them. Under the proposed framework, this can be done in an optimised fashion. The point here consists in applying probabilistic sensitivity analysis together with the fundamentals of the economic value of information; the framework as built is well suited to such considerations, and variables can be ranked according to their contribution to risk understanding. Efforts to deal with second order uncertainties on variables prove to be valuable when dealing with the economic value of sample information.
In order to give adequate support to riskmanagers, new risk assessment methods should be developed that are (1) scientifically sound, (2) simplified, and (3) suited for precautionary riskmanagement. In this Perspective we propose that the notion of a precautionary default can be a useful tool in the development of such methods. A precautionary default is a cautious or

Health risks associated with long periods of time in flight are of concern to astronauts, crew members, and passengers. Many epidemiological studies showed that occupational and frequent flyers may be susceptible to ocular, cardiovascular, neurological, pulmonary, gastrointestinal, sensory, immunological, physiological, and even developmental disorders. In addition, the incidences of cancer and food poisoning are expected to be higher in such individuals. This article reviews health risks and risk factors associated with air travel, and discusses riskmanagement strategies. To reduce adverse health risks, risk factors such as radiation, infection, stress, temperature, pressure, and circadian rhythm need to be avoided or reduced to levels that are as low as technologically achievable to protect flight personnel and passengers.

Suicide remains a serious health care problem and a sentinel event tracked by The Joint Commission. Nurses are pivotal in evaluating risk and preventing suicide. Analysis of nurses' barriers to riskmanagement may lead to interventions to improve management of suicidal patients. These data emerged from a random survey of 454 oncology nurses' attitudes, knowledge of suicide, and justifications for euthanasia. Instruments included a vignette of a suicidal patient and a suicide attitude questionnaire. Results. Psychological factors (emotions, unresolved grief, communication, and negative judgments about suicide) complicate the nurse's assessment and treatment of suicidal patients. Some nurses (n = 122) indicated that euthanasia was never justified and 11 were unsure of justifications and evaluated each case on its merits. Justifications for euthanasia included poor symptom control, poor quality of life, incurable illness or permanent disability, terminal illness, and terminal illness with inadequate symptom control or impending death, patient autonomy, and clinical organ death. The nurses indicated some confusion and misconceptions about definitions and examples of euthanasia, assisted suicide, and double effect. Strategies for interdisciplinary clinical intervention are suggested to identify and resolve these psychosocial barriers.
Recent emphasis within policy circles has been on transparent communication with consumers about food riskmanagement decisions and practices. As a consequence, it is important to develop best practice regarding communication with the public about how food risks are managed. In the current study, the provision of information about regulatory enforcement, proactive riskmanagement, scientific uncertainty and risk variability were manipulated in an experiment designed to examine their impact on consumer perceptions of food riskmanagement quality. In order to compare consumer reactions across different cases, three food hazards were selected (mycotoxins on organically grown food, pesticide residues, and a genetically modified potato). Data were collected from representative samples of consumers in Germany, Greece, Norway and the UK. Scores on the "perceived food riskmanagement quality" scale were subjected to a repeated-measures mixed linear model. Analysis points to a number of important findings, including the existence of cultural variation regarding the impact of risk communication strategies-something which has obvious implications for pan-European risk communication approaches. For example, while communication of uncertainty had a positive impact in Germany, it had a negative impact in the UK and Norway. Results also indicate that food riskmanagers should inform the public about enforcement of safety laws when communicating scientific uncertainty associated with risks. This has implications for the coordination of risk communication strategies between risk assessment and riskmanagement organizations. PMID:17945386

The discipline of probabilistic risk analysis (PRA) has become so mature in recent years that it is now being used routinely to assist decision-making throughout the nuclear industry. This includes decision-making that affects design, construction, operation, maintenance, and regulation. Unfortunately, not all sub-areas within the larger discipline of PRA are equally mature,'' and therefore the many different types of engineering insights from PRA are not all equally reliable. 93 refs., 4 figs., 1 tab.

This report addresses the general data requirements for reliability analysis of fielded wind turbines and other wind plant equipment. The report provides a rationale for why this data should be collected, a list of the data needed to support reliability and availability analysis, and specific data recommendations for a Computerized Maintenance Management System (CMMS) to support automated analysis. This data collection recommendations report was written by Sandia National Laboratories to address the general data requirements for reliability analysis of operating wind turbines. This report is intended to help develop a basic understanding of the data needed for reliability analysis from a Computerized Maintenance Management System (CMMS) and other data systems. The report provides a rationale for why this data should be collected, a list of the data needed to support reliability and availability analysis, and specific recommendations for a CMMS to support automated analysis. Though written for reliability analysis of wind turbines, much of the information is applicable to a wider variety of equipment and analysis and reporting needs. The 'Motivation' section of this report provides a rationale for collecting and analyzing field data for reliability analysis. The benefits of this type of effort can include increased energy delivered, decreased operating costs, enhanced preventive maintenance schedules, solutions to issues with the largest payback, and identification of early failure indicators.
For energy utilities faced with expanded jurisdictional energy efficiency requirements and pursuing demand-side management (DSM) incentive programs in the large industrial sector, performance incentive programs can be an effective means to maximize the reliability of planned energy savings. Performance incentive programs balance the objectives of high participation rates with persistent energy savings by: (1) providing financial incentives and resources to minimize constraints to investment in energy efficiency, and (2) requiring that incentive payments be dependent on measured energy savings over time. As BC Hydro increases its DSM initiatives to meet the Clean Energy Act objective to reduce at least 66 per cent of new electricity demand with DSM by 2020, the utility is faced with a higher level of DSM risk, or uncertainties that impact the costeffective acquisition of planned energy savings. For industrial DSM incentive programs, DSM risk can be broken down into project development and project performance risks. Development risk represents the project ramp-up phase and is the risk that planned energy savings do not materialize due to low customer response to program incentives. Performance risk represents the operational phase and is the risk that planned energy savings do not persist over the effective measure life. DSM project development and performance risks are, in turn, a result of industrial economic, technological and organizational conditions, or DSM risk factors. In the BC large industrial sector, and characteristic of large industrial sectors in general, these DSM risk factors include: (1) capital constraints to investment in energy efficiency, (2) commodity price volatility, (3) limited internal staffing resources to deploy towards energy efficiency, (4) variable load, process-based energy saving potential, and (5) a lack of organizational awareness of an operation's energy efficiency over time (energy performance). This research assessed the capacity of alternative performance incentive program models to manage DSM risk in BC. Three performance incentive program models were assessed and compared to BC Hydro's current large industrial DSM incentive program, Power Smart Partners -- Transmission Project Incentives, itself a performance incentive-based program. Together, the selected program models represent a continuum of program design and implementation in terms of the schedule and level of incentives provided, the duration and rigour of measurement and verification (M&V), energy efficiency measures targeted and involvement of the private sector. A multi criteria assessment framework was developed to rank the capacity of each program model to manage BC large industrial DSM risk factors. DSM riskmanagement rankings were then compared to program costeffectiveness, targeted energy savings potential in BC and survey results from BC industrial firms on the program models. The findings indicate that the reliability of DSM energy savings in the BC large industrial sector can be maximized through performance incentive program models that: (1) offer incentives jointly for capital and low-cost operations and maintenance (O&M) measures, (2) allow flexible lead times for project development, (3) utilize rigorous M&V methods capable of measuring variable load, process-based energy savings, (4) use moderate contract lengths that align with effective measure life, and (5) integrate energy management software tools capable of providing energy performance feedback to customers to maximize the persistence of energy savings. While this study focuses exclusively on the BC large industrial sector, the findings of this research have applicability to all energy utilities serving large, energy intensive industrial sectors.

This column is the fourth in a series describing a model for therapeutic riskmanagement of the suicidal patient. Previous columns presented an overview of the therapeutic riskmanagement model, provided recommendations for how to augment risk assessment using structured assessments, and discussed the importance of risk stratification in terms of both severity and temporality. This final column in the series discusses the safety planning intervention as a critical component of therapeutic riskmanagement of suicide risk. We first present concerns related to the relatively common practice of using no-suicide contracts to managerisk. We then present the safety planning intervention as an alternative approach and provide recommendations for how to use this innovative strategy to therapeutically mitigate risk in the suicidal patient.

This paper proposes an application of data mining to medical riskmanagement, where data mining techniques were applied to detection, analysis and evaluation of risks potentially existing in clinical environments. We applied this technique to the following two medical domains: risk aversion of nurse incidents and infection control. The results show that data mining methods were effective to detection and aversion of risk factors.
The need for more effective ways to manage the risk and safety of technological systems has been widely recognized and accepted by government and industry. Traditionally, risk analysis has been considered as part of the process of planning a technological system and addressed the risk inherent in its day-to-day operations. However, risk must also be considered when responding to episodic
In this paper we introduce the notion of data supply chain management and draw parallels between supply chain management and developing a data product. Then we discuss information sharing in supply chain management and discuss risks and incentives for inf...
There are both incentives and challenges for applying formal riskmanagement processes to buildings and other structures, including bridges, highways, dams, stadiums, shopping centers, and private dwellings. Based on an assessment of several issues, the authors conclude that for certain types of buildings and structures the time has come for the use of a formal risk-management approach, including probabilistic risk assessment methods, to help identify dominant risks to public health, safety, and security and to help manage these risks in a cost-effective manner.
As NASA Project RiskManagement activities continue to evolve, the need to successfully integrate riskmanagement processes across the life cycle, between functional disciplines, stakeholders, various management policies, and within cost, schedule and performance requirements/constraints become more evident and important. Today's programs and projects are complex undertakings that include a myriad of processes, tools, techniques, management arrangements and other variables all of which must function together in order to achieve mission success. The perception and impact of risk may vary significantly among stakeholders and may influence decisions that may have unintended consequences on the project during a future phase of the life cycle. In these cases, risks may be unintentionally and/or arbitrarily transferred to others without the benefit of a comprehensive systemic risk assessment. Integrating risk across people, processes, and project requirements/constraints serves to enhance decisions, strengthen communication pathways, and reinforce the ability of the project team to identify and managerisks across the broad spectrum of project management responsibilities. The ability to identify risks in all areas of project management increases the likelihood a project will identify significant issues before they become problems and allows projects to make effective and efficient use of shrinking resources. By getting a total team integrated risk effort, applying a disciplined and rigorous process, along with understanding project requirements/constraints provides the opportunity for more effective riskmanagement. Applying an integrated approach to riskmanagement makes it possible to do a better job at balancing safety, cost, schedule, operational performance and other elements of risk. This paper will examine how people, processes, and project requirements/constraints can be integrated across the project lifecycle for better riskmanagement and ultimately improve the chances for mission success.

Stroke is an uncommon but increasingly recognised cause of mortality and long-term neurological morbidity in children. A significant number of these events appear to be caused by thromboembolic disease and, as with other childhood thrombotic problems, the incidence of central nervous system events appears highest during the neonatal period. In contrast to peripheral arterial and venous thrombotic problems, it is likely that a proportion of cerebral thromboembolic events occur either in utero or perinatally and reflect different risk factors from those occurring in older infants and children. The pathophysiology of perinatal stroke is complex and in many cases is likely to be multifactorial. It is now recognised that risk factors may relate to both maternal and placental problems as well as fetal and neonatal disorders. Large prospective studies of perinatal stroke are currently lacking and efforts to define the relative contribution from each of these areas are at an early stage. The complex nature of these disorders requires collaboration between a number of different disciplines including obstetrics, fetal medicine, pathology, neonatology and neurology. Of particular interest to haematologists is the possible impact of prothrombotic abnormalities in the pathophysiology of these events and also the potential for the use of antithrombotic agents in both management and prevention.

There are at least nine major cancer susceptibility syndromes that infer an increased risk for colorectal cancer and/or colorectal polyposis; hereditary nonpolyposis colorectal cancer syndrome, Muir-Torre syndrome, Turcot syndrome, the I1307K polymorphism of the APC gene, familial adenomatous polyposis, attenuated familial adenomatous polyposis, Peutz Jeghers syndrome, juvenile polyposis, and the PTEN hamartoma tumor syndrome. As a result, the differential diagnosis of hereditary colorectal cancer can be complex. In addition, there has been a dramatic increase in the knowledge available regarding risk assessment and management of hereditary colorectal cancer syndromes. The literature was reviewed to develop this concise review of the hereditary colorectal cancer syndromes to facilitate the accurate diagnosis of each syndrome and the appropriate medical care for individuals with these diagnoses. Referral to a qualified Clinical Cancer Genetics program is appropriate if any of these syndromes is suspected and they will ensure the most up-to-date information is available to the patient, their family, and their health care professionals.

This research establishes that sustainability appraisal (SA) has a role to play in strengthening spatial plans in the context of flooding issues. Indeed, evidence has been gathered to indicate that tentative steps are being taken in this direction during the SA of English regional spatial plans, which are used as an illustrative case study. In England as in many other countries, appraisal procedures including SA and strategic environmental assessment (SEA) are enshrined in planning law. An opportunity therefore exists to utilise existing and familiar planning tools to embed flooding considerations within spatial plans at an early stage in the planning process. SA (and similar appraisal tools such as SEA) can therefore usefully aid in the implementation of decision making principles and government policy relating to flooding. Moreover, with the threats associated with climate change becoming increasingly apparent, of which increased flood risk is a particular concern in many countries, there is a need develop appropriate adaptation responses. This article emphasizes the role that SA can play in managing future flood risk in this context.

The aim of this study is to translate into the Turkish language, and test the reliability and validity, of the Turkish version of the Constipation Risk Assessment Scale (CRAS). This study consisted of 245 adult in-patients who were hospitalized in the medical and surgical clinics of Celal Bayar University Hospital in January through May 2007. The patients were categorized into two groups (constipated and not constipated) according to Rome II criteria. All participants were assessed with the CRAS. The CRAS was retested on 32 patients selected randomly from among the initial constipated group (n =152). The statistical analysis consisted of reliability and validity analyses. Test-retest comparison and internal consistency were used to assess the reliability of the instrument. Divergence and known groups approaches were used to test for construct validity. Correlation analysis using the Pearson's coefficient was conducted to assess the test-retest. For testing of the criteria and known groups, Student's t test and Mann-Whitney U test were used. Cronbach's = value for the constipated respondents was r = 61.9. According to the effect size comparisons, the most effective variable on the CRAS score was perception of constipation risk requirement. The overall score and subsection score correlations were also found acceptable (r = 0.47-0.57). PMID:21637085

Conventional solid waste management planning usually focuses on economic optimization, in which the related environmental impacts or risks are rarely considered. The purpose of this paper is to illustrate the methodology of how optimization concepts and techniques can be applied to structure and solve riskmanagement problems such that the impacts of air pollution, leachate, traffic congestion, and noise increments can be regulated in the iong-term planning of metropolitan solid waste management systems. Management alternatives are sequentially evaluated by adding several environmental risk control constraints stepwise in an attempt to improve the management strategies and reduce the risk impacts in the long run. Statistics associated with those risk control mechanisms are presented as well. Siting, routing, and financial decision making in such solid waste management systems can also be achieved with respect to various resource limitations and disposal requirements.

A Simplified Risk Model (SRM) is being developed to support environmental restoration and waste management (EM) planning activities. The SRM is designed to be able to quantitatively estimate risk for various EM alternatives within hours or days, given limited information about the processes covered within the alternative. The risk model covers radiological, chemical, and industrial risk from both accidents and normal, incident free operations. A simple risk equation is used to model accident risk. Normal, incident free operation risk is modeled using a multiplier on accident risk. Ongoing applications of the SRM are expected to lead to significant improvements to the model in the near future.
Introduction Planning for ways to reduce wildfire risk to communities and historic structures is an important element of modern land management. Wildfire riskmanagement is most successful if it is based on the best available science and incorporates reliable information on the ecological characteristics of the target landscape. It is also important to have explicit social and ecological objectives that
The ARRAMIS risk and reliability analysis software suite developed by Sandia National Laboratories enables analysts to evaluate the safety and reliability of a wide range of complex systems whose failure results in high consequences. This software was originally designed to model the systems, responses, and phenomena associated with potential severe accidents at commercial nuclear power reactors by solving very large fault tree and event tree models. However, because of its power and versatility, ARRAMIS and its constituent analysis engines have recently been used to evaluate a wide variety of systems, including nuclear weapons, telecommunications facilities, robotic material handling systems, and aircraft systems using hybrid fault tree event tree analysis techniques incorporating fully integrated uncertainty analysis capabilities. This paper describes recent applications in the area of nuclear reactor accident progression analysis using a large event tree methodology and the ARRAMIS package.

This study analyzes the risk-taking behavior of mutual funds in response to their rel- ative performance over the 1992 to 1999 period. Our results show that managers of funds whose performance is closer to that of the top performing funds have greater incentives to increase their portfolios' risk than managers at the top who exhibit a tendency to lock in
The financial crisis of 2008 and the resulting recession caught many companies unprepared and, in so doing, provided a stark reminder of the importance of effective riskmanagement. While academic theory has long touted the benefits of riskmanagement, companies have varied greatly in the ways and extent to which they put theory into practice.Drawing on a global survey of
Software projects are increasingly geographically distributed with limited face-to-face interaction between participants. These projects face particular challenges that need careful managerial attention. While riskmanagement has been adopted with success to address other challenges within software development, there are currently no frameworks available for managingrisks related to geographical distribution. On this background, we systematically review the literature on geographically

In this paper, we argue that vulnerability is a new perspective in riskmanagement. Organizational vulnerability is identified by lack of adaptive capacity and resilience and these two elements determine the success of organizational riskmanagement simultaneously. We believe that emerging insights into organizational vulnerability complement and can significantly add to a converging research agenda on the challenges faced by

Ideas from a USA-FRG conference on riskmanagement are presented. In general, the difficulties confronted by riskmanagement authorities in the two countries are similar, from discovering important risks at an early stage to setting acceptable goals. Government regulation is overburdened and somewhat inefficient in both countries, leading to greater search for alternatives. The many differences in approach between the two countries can inform both. German riskmanagement is done largely through negotiations among the affected parties; when this does not resolve a dispute, a specialized administrative court takes charge. In both countries nonregulatory methods of managingrisk should be enhanced and given a larger role. A matrix of riskmanagement method versus criteria proved stimulating in comparing and ranking approaches. The conceptual differences between managing discrete events and chronic exposures have not been appreciated. Although uncertainty and probability are involved in both, there are qualitative differences in both analysis and management. Public perceptions of risk and the role these should play have been characterized by ''objectivist'' and ''subjectivist'' positions. In the former view, risks are subject to analysis, are calculable, and the public must be educated to accept the conclusions of experts. In the latter view what people perceive is what is most important, both psychologically and politically, and the risk experts must understand public fears and desires. These are important opportunities for cross cultural studies.
Risks, uncertainties in firms and their environment are increasingly dealt with strategic planning, risk analysis and riskmanagement. The present state of strategic planning enables us to consider the greatest part of internal and environmental risks mainly qualitatively - due to the fact that the majority of planning models used are of a deterministic type.
The 1994 Accident Sequence Precursor (ASP) human reliability analysis (HRA) methodology was developed for the U.S. Nuclear Regulatory Commission (USNRC) in 1994 by the Idaho National Engineering and Environmental Laboratory (INEEL). It was decided to revise that methodology for use by the Simplified Plant Analysis Risk (SPAR) program. The 1994 ASP HRA methodology was compared, by a team of analysts, on a point-by-point basis to a variety of other HRA methods and sources. This paper briefly discusses how the comparisons were made and how the 1994 ASP HRA methodology was revised to incorporate desirable aspects of other methods. The revised methodology was renamed the SPAR HRA methodology.

Most senior police officials are competent when it comes to assessing and managing physical risk during the course of law enforcement activities. Some even have aptitude for managing sociopolitical risks, but they are much rarer and are usually found in larger departments, which can afford to send senior officers to public speaking and media-management courses. There are tools that can be adapted from industrial safety to aid in managing sociopolitical risks in law enforcement activities. One such tool is the HAZards and OPerability Study (HAZOPS)tool1. This tool is basically a systemic method of performing 'what if' studies. This tool, and some others, are described in this paper.
The 5th Aquatic Animal Models for Human Disease meeting follows four previous meetings (Hinton et al., 2009; Schmale et al., 2007; Schmale, 2004; Nairn et al., 2001) in which advances in aquatic animal models for human disease research were reported, and community discussion of future direction was pursued. At this meeting, discussion at a workshop entitled Bioinformatics and Computational Biology with Web-based Resources (20 September 2010) led to an important conclusion: Aquatic model research using feral and experimental fish, in combination with web-based access to annotated anatomical atlases and toxicological databases, yield data that advance our understanding of human gene function, and can be used to facilitate environmental management and drug development. We propose here that the effects of genes and environment are best appreciated within an anatomical context - the specifically affected cells and organs in the whole animal. We envision the use of automated, whole-animal imaging at cellular resolution and computational morphometry facilitated by high-performance computing and automated entry into toxicological databases, as anchors for genetic and toxicological data, and as connectors between human and model system data. These principles should be applied to both laboratory and feral fish populations, which have been virtually irreplaceable sentinals for environmental contamination that results in human morbidity and mortality. We conclude that automation, database generation, and web-based accessibility, facilitated by genomic/transcriptomic data and high-performance and cloud computing, will potentiate the unique and potentially key roles that aquatic models play in advancing systems biology, drug development, and environmental riskmanagement.

This article describes how features of event tree analysis and Monte Carlo-based discrete event simulation can be combined with concepts from object-oriented analysis to develop a new risk assessment methodology, with some of the best features of each. The resultant object-based event scenario tree (OBEST) methodology enables an analyst to rapidly construct realistic models for scenarios for which an a priori discovery of event ordering is either cumbersome or impossible. Each scenario produced by OBEST is automatically associated with a likelihood estimate because probabilistic branching is integral to the object model definition. The OBEST methodology is then applied to an aviation safety problem that considers mechanisms by which an aircraft might become involved in a runway incursion incident. The resulting OBEST model demonstrates how a close link between human reliability analysis and probabilistic risk assessment methods can provide important insights into aviation safety phenomenology.

In this article the results of explorative research into the validity and reliability of a Dutch version of the Bradenscale are described. The Bradenscale is a risk assessment tool for measuring the risk of developing pressure sores. With a prospective longitudinal design the Bradenscale has been investigated in a hospital and a community setting in Belgium and the Netherlands. Results of the research in hospital indicate a fair to moderate agreement with respect to interraterreliability and a reasonable amount of predictive validity. In the community care setting interraterreliability indicates slight to fair agreement while predictive validity could not be established due to several reasons. Further research into the Bradenscale is recommended considering the limited research population in both studies and the results in community care. PMID:9516819
Contracting overseas construction projects is usually considered a ‘high risk business’, mostly because of a lack of adequate overseas environmental information and overseas construction experience.

The field of disaster riskmanagement is relatively new and takes a structured approach to managing uncertainty related to the threat of natural and man-made disasters. Disaster riskmanagement consists primarily of risk assessment and the development of strategies to mitigate disaster risk. This paper will discuss how increasing both Earth observation data and information technology capabilities can contribute to disaster riskmanagement, particularly in Belize. The paper presents the results and recommendations of a project conducted by an international and interdisciplinary team of experts at the 2009 session of the International Space University in NASA Ames Research Center (California, USA). The aim is to explore the combination of current, planned and potential space-aided, airborne, and ground-based Earth observation tools, the emergence of powerful new web-based and mobile data management tools, and how this combination can support and improve the emerging field of disaster riskmanagement. The starting point of the project was the World Bank's Comprehensive Approach to Probabilistic Risk Assessment (CAPRA) program, focused in Central America. This program was used as a test bed to analyze current space technologies used in riskmanagement and develop new strategies and tools to be applied in other regions around the world.
The evaluation of the need for remedial activities at hazardous waste sites requires quantification of risks of adverse health effects to humans and the ecosystem resulting from the presence of chemical and radioactive substances at these sites. The health risks from exposure to these substances are in addition to risks encountered because of the virtually unavoidable exposure to naturally occurring chemicals and radioactive materials that are present in air, water, soil, building materials, and food products. To provide a frame of reference for interpreting risks quantified for hazardous waste sites, it is useful to identify the relative magnitude of risks of both a voluntary and involuntary nature that are ubiquitous throughout east Tennessee. In addition to discussing risks from the ubiquitous presence of background carcinogens in the east Tennessee environment, this report also presents risks resulting from common, everyday activities. Such information should, not be used to discount or trivialize risks from hazardous waste contamination, but rather, to create a sensitivity to general risk issues, thus providing a context for better interpretation of risk information.
Climate variability and change impact national and local economies and environments. Developing and communicating climate and climate impacts information to inform decision making requires an understanding of context, societal objectives, and identification of factors important to the management of risk. Information sensitive to changing baselines or extremes is a critical emergent need. Meeting this need requires timely production and delivery of useful climate data, information and knowledge within familiar pathways. We identify key attributes for a climate service , and the network and infrastructure to develop and coordinate the resulting services based on lessons learned in experimental implementations of climate services. "Service-type" activities already exist in many settings within federal, state, academic, and private sectors. The challenge for a climate service is to find effective implementation strategies for improving decision quality (not just meeting user needs). These strategies include upfront infrastructure investments, learning from event to event, coordinated innovation and diffusion, and highlighting common adaptation interests. Common to these strategies is the production of reliable and accessible data, analyses of emergent conditions and needs, and deliberative processes to identify appropriate entry points and uses for improved knowledge. Experimental climate services show that the development of well-structured paths among observations, projections, risk assessments and usable information requires sustained participation in “knowledge management systems” for early warning across temporal and spatial scales. Central to these systems is a collaborative framework between research and management to ensure anticipatory coordination between decision makers and information providers, allowing for emerging research findings and their attendant uncertainties to be considered. Early warnings in this context are not simply forecasts or predictions but information on potential “futures” derived from past records, expert judgments, scenarios, and availability of mechanisms and capacity to use such information. Effective experimental climate services facilitate ongoing appraisals of knowledge needs for informing adaptation and mitigation options across sectors and across scenarios of near and longer-term future climates. Analyses show that climate service experiments drawing on data, applied research and prototyping functions of activities such as RISAs and RCCs are critical to developing the learning needed to inform and structure the flow of knowledge and understanding from problem definition and applications research to information delivery, use and evaluation. These activities effectively serve to inform services implementation when overarching cross-agency coordination, knowledge management, and innovation diffusion mechanisms such as afforded by NIDIS and the Coastal Services Center are engaged. We also demonstrate the importance of positioning climate research to engage and inform the decision-making process as society anticipates and responds to climate and its impacts.

The New Basel Capital Accord has firstly covered almost all risk sources including credit risk, market risk and operational risk etc. and embodied an outlook of complete riskmanagement. In the past five years, state-owned commercial banks and stock-system commercial banks have made certain progress in riskmanagement culture and in improving various riskmanagement means, but it is still
The U.S. bank supervisory agencies recently issued for public comment revised guidance regarding the implementation of the proposed Basel II-related, risk-based capital requirements. Among the revisions is an important update to guidance regarding operational riskmanagement. Operational risk generally refers to the risk of monetary losses resulting from inadequate or failed internal processes, people, and systems, or from external events,

Carriers of germline mutations in the TP53 gene, encoding the cell-cycle regulator and tumour suppressor p53, have a markedly increased risk of cancer-related morbidity and mortality during both childhood and adulthood, and thus require appropriate and effective cancer riskmanagement. However, the predisposition of such patients to multiorgan tumorigenesis presents a specific challenge for cancer riskmanagement programmes. Herein, we review the clinical implications of germline mutations in TP53 and the evidence for cancer screening and prevention strategies in individuals carrying such mutations, as well as examining the potential psychosocial implications of lifelong management for a ubiquitous cancer risk. In addition, we propose an evidence-based framework for the clinical management of TP53 mutation carriers and provide a platform for addressing the management of other cancer predisposition syndromes that can affect multiple organs.

Working toward effective risk mitigation strategies amidst ever-present and increasingly changing risks requires first effective communication between assessment and management spheres. This notion permeates the spectrum of what can be considered the physical changing risk inputs that feed into the risk governance processes of assessment, management and communication of risks. Close connections and overlaps between assessment and management requires communication to serve as the crux for the close collaboration necessary for encouraging preventative, long-term strategies for reducing disaster risks.1 More specifically, communication of risk information plays this connective role by informing and advising policy and decision making processes conducted by actors such as spatial planners who receive this information. In this way, those who assess the risks provide information to those who must manage these risks. When this one-directional communication pathway is reciprocated, riskmanagers provide information to risk assessors, enabling two-way communication amongst actors working toward risk reduction. This communication and exchange of information enables development of strategies and actions taken toward creating and improving risk mitigation measures within a given territory and community. Further, management actions taken (especially for mitigative measures) can alter the physical and social elements of the spatial context of their territory.2 This demands an adjustment of the previous risk assessment information and communication of the change in potential risk. These conceptual underpinnings are addressed and presented through explanation of an analytical framework encompassing changing risk inputs into risk governance processes. The framework elaborates the risk communication component and is supported by practical examples from stakeholder meetings and site visits in the Polish and Romania case study areas of the Marie Curie ITN, CHANGES.3 Specific examples are provided especially within the topic of mitigation through spatial planning, as one of the riskmanagement actors using the provided risk information to implement effective measures. Results of example analysis indicate that, in Poland, alteration in risk assessment methods according to the implementation of the EU Floods Directive may be detrimental to local level management strategies. In the case of Romania, evidence suggests that severe deficiencies exist in the communication and use of risk assessment information especially in the formation and implementation of land use plans. Utilizing these and other examples, the research concludes with some key points gleaned from the combination of the both conceptual and practical approach in order to foster dialogue and discussion toward future research.

Background, aim, and scope This paper presents a study related to the application of the reliability-based life cycle assessment (LCA) to assess different\\u000a alternatives for solid waste management in the Setúbal peninsula, Portugal. The current system includes waste collection,\\u000a transport, sorting, recycling, and mechanical and biological treatment (MBT) by means of aerobic treatment and landfill. In\\u000a addition, some future expansion plans
Background Foot disease complications, such as foot ulcers and infection, contribute to considerable morbidity and mortality. These complications are typically precipitated by “high-risk factors”, such as peripheral neuropathy and peripheral arterial disease. High-risk factors are more prevalent in specific “at risk” populations such as diabetes, kidney disease and cardiovascular disease. To the best of the authors’ knowledge a tool capturing multiple high-risk factors and foot disease complications in multiple at risk populations has yet to be tested. This study aimed to develop and test the validity and reliability of a Queensland High Risk Foot Form (QHRFF) tool. Methods The study was conducted in two phases. Phase one developed a QHRFF using an existing diabetes foot disease tool, literature searches, stakeholder groups and expert panel. Phase two tested the QHRFF for validity and reliability. Four clinicians, representing different levels of expertise, were recruited to test validity and reliability. Three cohorts of patients were recruited; one tested criterion measure reliability (n?=?32), another tested criterion validity and inter-rater reliability (n?=?43), and another tested intra-rater reliability (n?=?19). Validity was determined using sensitivity, specificity and positive predictive values (PPV). Reliability was determined using Kappa, weighted Kappa and intra-class correlation (ICC) statistics. Results A QHRFF tool containing 46 items across seven domains was developed. Criterion measure reliability of at least moderate categories of agreement (Kappa?>?0.4; ICC?>?0.75) was seen in 91% (29 of 32) tested items. Criterion validity of at least moderate categories (PPV?>?0.7) was seen in 83% (60 of 72) tested items. Inter- and intra-rater reliability of at least moderate categories (Kappa?>?0.4; ICC?>?0.75) was seen in 88% (84 of 96) and 87% (20 of 23) tested items respectively. Conclusions The QHRFF had acceptable validity and reliability across the majority of items; particularly items identifying relevant co-morbidities, high-risk factors and foot disease complications. Recommendations have been made to improve or remove identified weaker items for future QHRFF versions. Overall, the QHRFF possesses suitable practicality, validity and reliability to assess and capture relevant foot disease items across multiple at risk populations.
In classical theory, the risk is limited to mathematical expectation of losses that can occur when choosing one of the possible variants. For banks, risk is represented as losses arising from the completion of one or another decision. Bank risk is a phenomenon that occurs during the activity of banking operations and that cause negative effects for those activities: deterioration

The project entitled, “Uncertainty Quantification in the Reliability and Risk Assessment of Generation IV Reactors”, was conducted as a DOE NERI project collaboration between Texas A&M University and The Ohio State University between March 2006 and June 2009. The overall goal of the proposed project was to develop practical approaches and tools by which dynamic reliability and risk assessment techniques can be used to augment the uncertainty quantification process in probabilistic risk assessment (PRA) methods and PRA applications for Generation IV reactors. This report is the Final Scientific/Technical Report summarizing the project.
Decision support systems for nuclear emergency management (DSNE) are currently used worldwide to assist decision makers in taking emergency response countermeasures in case of accidental releases of radioactive materials from nuclear facilities. The present work has been motivated by the fact that, up until now, DSNE systems have not been regarded as safety critical software systems. The core of any DSNE system is represented by the different simulation codes linked together to form the dispersion simulation workflow. These codes require input emission and meteorological data to produce forecasts of the atmospheric dispersion of radioactive pollutants and other substances. However, the reliability of the system not only depends on the trustworthiness of the measured (or generated) input data but also on the reliability of the simulation codes used. The main goal of this work is to improve the reliability of DSNE systems by adapting current state of the art methods from the domain of software reliability engineering to the case of atmospheric dispersion simulation codes. The current approach is based on the "design by diversity principle" for improving the reliability of simulation codes and the trustworthiness of simulation results. The effectiveness of the approach has been tested using the results of two test versions of the RODOS DSNE system used in several European countries.

For new access to space systems with challenging mission requirements, effective implementation of integrated system health management (ISHM) must be available early in the program to support the design of systems that are safe, reliable, highly autonomous. Early ISHM availability is also needed to promote design for affordable operations; increased knowledge of functional health provided by ISHM supports construction of more efficient operations infrastructure. Lack of early ISHM inclusion in the system design process could result in retrofitting health management systems to augment and expand operational and safety requirements; thereby increasing program cost and risk due to increased instrumentation and computational complexity. Having the right sensors generating the required data to perform condition assessment, such as fault detection and isolation, with a high degree of confidence is critical to reliable operation of ISHM. Also, the data being generated by the sensors needs to be qualified to ensure that the assessments made by the ISHM is not based on faulty data. NASA Glenn Research Center has been developing technologies for sensor selection and data validation as part of the FDDR (Fault Detection, Diagnosis, and Response) element of the Upper Stage project of the Ares 1 launch vehicle development. This presentation will provide an overview of the GRC approach to sensor selection and data quality validation and will present recent results from applications that are representative of the complexity of propulsion systems for access to space vehicles. A brief overview of the sensor selection and data quality validation approaches is provided below. The NASA GRC developed Systematic Sensor Selection Strategy (S4) is a model-based procedure for systematically and quantitatively selecting an optimal sensor suite to provide overall health assessment of a host system. S4 can be logically partitioned into three major subdivisions: the knowledge base, the down-select iteration, and the final selection analysis. The knowledge base required for productive use of S4 consists of system design information and heritage experience together with a focus on components with health implications. The sensor suite down-selection is an iterative process for identifying a group of sensors that provide good fault detection and isolation for targeted fault scenarios. In the final selection analysis, a statistical evaluation algorithm provides the final robustness test for each down-selected sensor suite. NASA GRC has developed an approach to sensor data qualification that applies empirical relationships, threshold detection techniques, and Bayesian belief theory to a network of sensors related by physics (i.e., analytical redundancy) in order to identify the failure of a given sensor within the network. This data quality validation approach extends the state-of-the-art, from red-lines and reasonableness checks that flag a sensor after it fails, to include analytical redundancy-based methods that can identify a sensor in the process of failing. The focus of this effort is on understanding the proper application of analytical redundancy-based data qualification methods for onboard use in monitoring Upper Stage sensors.
The Ministry of Health in Italy considers riskmanagement (RM) to be one of the specific objectives to be developed by its national policies, as suggested by the European Union recommendations and by several international organizations, such as the World Health Organization (WHO), the Council of Europe, and the Organization for Economic Cooperation and Development. The National Health Plan stated the need to guarantee and monitor safety of health care and biomedical technology, with the development of a standardized computerized method to collect and analyze data on adverse events and with specific actions for education and training of all stakeholders, which is to be conducted at different levels of the health system governance, national, regional, and local. Over a 4-year period, the National Observatory for the Monitoring of Sentinel Events has collected data on 385 sentinel events, with a mortality rate of 54.8%. Compared with earlier reports, we have observed a reduction from 41% to 17% of sentinel events classified in the "nonspecified sentinel event" and an increase from 20% to 40% of cases in which an action plan has been developed. A manual for root cause analysis has been released with the aim of offering health operators an instrument to analyze the occurrence of an adverse event. Ten recommendations and a manual for safety in the operating room, which includes a checklist for safe surgery adapted on the basis of WHO suggestions, have been published. To date, eight guidelines for safety have been released to improve stakeholders' accountability. The Ministry of Health has also elaborated a program of specific actions to be developed over the next 2 years in several areas of RM. These initiatives confirm the strategic role of policies for RM in our country, allowing for a dynamic and proactive process, ensuring continuity of action and promoting a deep understanding of patient safety issues.

Launching a rocket, running a business, driving to work and even day-to-day living all involve some degree of risk. Risk is ever present yet not always recognized, adequately assessed and appropriately mitigated. Identification, assessment and mitigation of risk are elements of the riskmanagement component of the "continuous improvement" way of life that has become a hallmark of successful and progressive enterprises. While the application of riskmanagement techniques to provide continuous improvement may be detailed and extensive, the philosophy, ideals and tools can be beneficially applied to all situations. Experiences with the use of risk identification, assessment and mitigation techniques for complex systems and processes are described. System safety efforts and tools used to examine potential risks of the Ares I First Stage of NASA s new Constellation Crew Launch Vehicle (CLV) presently being designed are noted as examples. Recommendations from lessons learned are provided for the application of riskmanagement during the development of new systems as well as for the improvement of existing systems. Lessons learned and suggestions given are also examined for applicability to simple systems, uncomplicated processes and routine personal daily tasks. This paper informs the reader of varied uses of riskmanagement efforts and techniques to identify, assess and mitigate risk for improvement of products, success of business, protection of people and enhancement of personal life.

The importance of treating this theme is proved by the current situation that economy and the entities activating on the market are confronted with. Risk is present in all the actions and event of humanity.

Risk assessments and riskmanagement decisions concerning risks to wild fish populations resulting from exposures to polychlorinated biphenyls (PCBs) and related chemicals have been based primarily on observations of effects of chemicals on individual organisms. Although the development and application of population-level ecological risk-assessment methods is proceeding at a rapid pace, the organism-level approach is still being justified by arguments that population-level ecological risk assessment is in an early stage of development and has not been shown to be reliable. This article highlights the importance of including population-level effects in risk-management decision-making, by examining the effects of exposures to PCBs on fish populations inhabiting the Hudson River, New York, USA, a system in which data have been collected for approximately 30 y concerning both concentrations of PCBs in sediment and fish tissue and the abundance and reproduction of exposed fish populations. We previously tested hypotheses concerning the effects of PCBs on the striped bass population of the Hudson River, and found that the available data conflicted with all of these hypotheses. Here, we report results of similar analyses of effects of historic PCB exposures on the Hudson River white perch population, using an extended data set that recently became available. As with striped bass, we found no correlation between maternal PCB tissue concentrations and any measure of reproductive success in Hudson River white perch during the 30-y period covered by the data set. Together with results of studies performed on fish populations exposed to PCBs at other sites, our results clearly demonstrate that physiological and genetic adaptation, biological compensation, and other ecological processes influence responses of fish populations to PCB exposures and should be considered in riskmanagement decision-making.

Ecological risk assessments are steadily becoming a significant part of the total environmental services picture. A properly conducted and well-managed baseline ecological risk assessment can provide significant information that is of real value in setting remediation or corrective measures goals. Although there is considerable technical guidance concerning ecological assessments, little help is available regarding management of an assessment as a project. As a result, assessments suffer from an absence of clear direction, objectives unrelated to riskmanagement needs, and poor quality data incapable of supporting desired riskmanagement decisions. This report proposes a flexible, generic work breakdown structure to integrate ecological risk assessment tasks to ensure that a baseline assessment is: (1) an ecotoxicological investigation focusing on ecological implications of toxicological phenomenon, (2) driven by site-specific, operationally defined endpoints and data quality objectives that provide high-certainty, pertinent information for riskmanagement decisions, and (3) a project of finite duration with goals and products constrained by budget and schedule considerations. This more consistent approach would allow a project manager to better define the ecological risk assessment process, enabling it to be a more effective part of remediation projects.

The exponentially growing losses related to natural disasters on a global scale reflect a changing risk landscape that is characterized by the influence of climate change and a growing population, particularly in urban agglomerations and coastal zones. In consequence of these trends we witness (a) new hazards such as landslides due to dwindling permafrost, new patterns of strong precipitation and related floods, potential for tropical cyclones in the Mediterranean, sea level rise and others; (b) new risks related to large numbers of people in very dense urban areas, and risks related to the vulnerability of infrastructure such as energy supply, water supply, transportation, communication, etc. (c) extreme events with unprecedented size and implications. An appropriate answer to these challenges goes beyond classical views of risk assessment and protection. It must include an understanding of risk as changing with time so that risk assessment needs to be supplemented by risk monitoring. It requires decision making under high uncertainty. The risks (i.e. potentials for future losses) of extreme events are not only high but also very difficult to quantify, as they are characterized by high levels of uncertainty. Uncertainties relate to frequency, time of occurrence, strength and impact of extreme events but also to the coping capacities of society in response to them. The characterization, quantification, reduction in the extent possible of the uncertainties is an inherent topic of extreme event research. However, they will not disappear, so a rational approach to extreme events must include more than reducing uncertainties. It requires us to assess and rate the irreducible uncertainties, to evaluate options for mitigation under large uncertainties, and their communication to societal sectors. Thus scientist need to develop methodologies that aim at a rational approach to extreme events associated with high levels of uncertainty.
In some places, geo-hazards are a major concern for population, the assets, and the economy. This is especially the case in the East African Rift (EAR), where high volcanic and tectonic activities are sometimes coupled with geopolitical issues and dense population as in the Kivu rift area. That area is one of the most densely populated regions of Central Africa and is affected by decades of political instability and subsequent humanitarian crisis. In that region, geo-hazards are poorly assessed despite the numerous recent and historical events. Moreover, the relief of the rift also corresponds in this area to the main political boundaries, which complicates the coordination and the management of geo-hazards monitoring networks and related mitigation measures. Based on the experience acquired through several projects focused on hazard assessment and reinforcement of local monitoring capacity, the GeoRisCA project is addressing the assessment of the global risk related to the major geohazards that affect the region. Taking into account the identified factors, GeoRisCA's objective is to assess the risk from multi geohazards in a region which is subject to many (possibly combined) disasters every year and which could undergo a large impact disaster in the coming years. At regional scale, the high seismicity and the volcanic activity are the most important concerns. Possible eruptions of lethal gas in certain area around Goma, and the large number of reported and likely future mass movements as well as site-specific seismic amplification effects increase the danger at local scale. As both human lives and specific ecosystems are under threat, comprehensive methodologies are required to reliably assess multi geohazards over both short and long terms and to clearly outline and map related risk. These tools are needed by local and regional authorities as well as local and international stakeholders in management and mitigation processes. Developed methodologies in GeoRisCA combine hazard and vulnerability factors, as well as risk perception indicators. Such an approach combining natural and human sciences to address georisks globally at a regional scale has never been performed in that region so far.
A Technical RiskManagement based on the Water Safety Plan (WSP) concept was implemented at four German water supply systems according to the recommendations of the World Health Organization (WHO). Hazards affecting water quality, continuity and the reliability of supply from catchment to treatment and distribution could be identified by the systematic approach and suitable measures were defined. The results
In its simplest form, riskmanagement is a continuous assessment from project start to completion that identifies what can impact your project (i.e., what the risks are)., which of these risks are important, and identification and implementation of strategies to deal with these risks (both threats and opportunities). The National Compact Stellerator Experiment (NCSX) Project was a "first-of-a-kind" fusion experiment that was technically very challenging, primarily resulting from the complex component geometries and tight tolerances. Initial risk quantification approaches proved inadequate and contributed to the escalation of costs as the design evolved and construction started. After the Project was well into construction, a new riskmanagement plan was adopted. This plan was based on successful Department of Energy (DOE) and industrial riskmanagement precepts. This paper will address the importance of effective riskmanagement processes and lessons learned. It is of note that a steady reduction of risk was observed in the last six months of the project.

Principles of riskmanagement, as a part of risk analysis, are described with respect to their application to the production chain of intensively reared fish. According to the outcomes of the FAO\\/WHO Expert Consultation on the Application of RiskManagement (Rome, 1997), there are four steps: risk evaluation, riskmanagement option assessment, implementation of management decisions, and monitoring and review.
The article describes challenges to comparative risk assessment, a key approach for managing uncertainty in decision making, across diverse threats such as terrorism and climate change and argues new approaches will be particularly important in addressing decisions related to sustainability.
