Debates about the desirability of widespread shale development have highlighted outstanding uncertainty about its health, safety, and environmental impacts—most prominently, its water-contamination risks—and the ability of current institutions to deal with these impacts. States, the primary regulators of oil and gas extraction, face pressure from the energy industry, local communities, and, in some cases, the federal government to strike the right balance between energy production and the health and safety of individuals and the environment—an elusive balance given the ongoing risk uncertainty. This dynamic is not especially unique to fracking, or even oil and gas extraction; instead, this dynamic, characterized by tradeoffs between environmental protection and economic development under risk uncertainty, is a common theme of environmental risk regulation. Regulators at every level of government weigh and evaluate potential interventions against this background. This Article contributes to a symposium held at Texas A&M School of Law that explores the advantages and disadvantages of various government interventions in the environmental context in an effort to identify ideal risk-management tools under various circumstances. It argues that the most important considerations for identifying risk-management tools in the environmental context are risks, incentives, and cost-benefit analysis. These cornerstone principles provide a useful framework for environmental policy in general, especially in situations that involve heterogeneous and uncertain risks. By paying attention to risk, incentives, and cost-benefit analysis, government regulators are more likely to promote optimal levels of environmental quality and avoid unintended, or even perverse, consequences. To demonstrate the usefulness of these concepts concretely, this Article applies them to the fracking context, focusing on the most prominent risks from widespread shale development, risks to water from shale gas extraction. It identifies risk-management gaps in tort litigation, insurance markets, and regulation schemes and suggests potential solutions.

The role of multiparametric MRI in diagnosis, staging and treatment planning for prostate cancer is well established. However there remain several challenges to widespread adoption. One such challenge is the duration and cost the examination. Abbreviated exams omitting contrast enhanced sequences may help address this challenge. In this review, we will discuss the rationale for biparametric MRI (bpMRI) for detection and characterization of clinically significant prostate cancer prior to biopsy and synthesize the published literature. We will weigh up the advantages and disadvantages to this approach and lay out a conceptual cost/benefit analysis regarding adoption of bpMRI.

Abstract. Citizen observatories are a relatively recent form of citizen science. As part of the flood risk management strategy of the Brenta-Bacchiglione catchment, a citizen observatory for flood risk management has been proposed and is currently being implemented. Citizens are involved through monitoring water levels and obstructions and providing other relevant information through mobile apps, where the data are assimilated with other sensor data in a hydrological-hydraulic model used in early warning. A cost benefit analysis of the citizen observatory was undertaken to demonstrate the value of this approach in monetary terms. Although not yet fully operational, the citizen observatory is assumed to decrease the social vulnerability of the flood risk. By calculating the hazard, exposure and vulnerability of three flood scenarios (required for flood risk management planning by the EU Directive on Flood Risk Management) with and without the proposed citizen observatory, it is possible to evaluate the benefits in terms of the average annual avoided damage costs. Although currently a hypothetical exercise, the results showed a reduction in avoided damage of 45 % compared to a business as usual scenario. Thus, linking citizen science with hydrological modelling, and to raise awareness of flood hazards, has great potential in reducing future flood risk in the Brenta-Bacchiglione catchment. Moreover, such approaches are easily transferable to other catchments.

Recent work in the philosophy of technology draws attention to the connection between technology and the good life. Discourse around emerging technologies also makes this connection, albeit implicitly, when it focuses on the promises and perils of going forward with a nascent technology. Emerging technologies are touted for their potential to bring about increased safety, health, convenience, or enlightenment and disparaged for their perils—diminished freedom, erosion of privacy, new vulnerabilities to nature. Use of the promises-and-perils framework is commonplace and rarely challenged. A comparison between the promises-and-perils framework and cost-benefit analysis reveals some of the advantages and disadvantages of promises-and-perils thinking. Uncertainty is an overarching problem and that makes plausibility important. How can the plausibility of promises and perils be assessed? A sociotechnical systems understanding of technology reveals at least three sources of uncertainty, and these provide some basis for evaluating the plausibility of promises and perils.

Abstract The National Institute for Standards and Technology (NIST) Cybersecurity Framework has rapidly become a widely accepted approach to facilitating cybersecurity risk management within organizations. An insightful aspect of the NIST Cybersecurity Framework is its explicit recognition that the activities associated with managing cybersecurity risk are organization specific. The NIST Framework also recognizes that organizations should evaluate their cybersecurity risk management on a cost–benefit basis. The NIST Framework, however, does not provide guidance on how to carry out such a cost–benefit analysis. This article provides an approach for integrating cost–benefit analysis into the NIST Cybersecurity Framework. The Gordon–Loeb (GL) Model for cybersecurity investments is proposed as a basis for deriving a cost-effective level of spending on cybersecurity activities and for selecting the appropriate NIST Implementation Tier level. The analysis shows that the GL Model provides a logical approach to use when considering the cost–benefit aspects of cybersecurity investments during an organization’s process of selecting the most appropriate NIST Implementation Tier level. In addition, the cost–benefit approach provided in this article helps to identify conditions under which there is an incentive to move to a higher NIST Implementation Tier.

Although currently a hypothetical exercise, the results showed a reduction in avoided damage of 45 % compared to a business as usual scenario. Thus, linking citizen science and citizen observatories with hydrological modelling to raise awareness of flood hazards and to facilitate two-way communication between citizens and local authorities has great potential in reducing future flood risk in the Brenta-Bacchiglione catchment. Moreover, such approaches are easily transferable to other catchments.

This paper performs cost-benefit analysis of a pipeline infrastructure project based on a given natural gas demand in order to estimate the net present value and payback time for natural gas pipeline investment in Nigeria. The result of the cost-benefit analysis indicates a positive net revenue and net present value (NPV) at the current regulated transport cost and availability factor for gas pipelines in Nigeria. However, with a payback period of 14 years, a natural gas pipeline project in Nigeria is likely to lose-out investment capital to other competing investments within the oil and gas sector. Scenario analysis indicates that by doubling the regulated transport cost with a 50% tax reduction, the pipeline investment results in a much higher NPV and a payback of 4 years, which is more acceptable to investors.
