We study the estimation of risk preferences with experimental data and focus on the trade-offs when choosing between two different
elicitation methods that have different degrees of difficulty for subjects. We analyze how and when a simpler, but coarser,
elicitation method may be preferred to the more complex, but finer, one. Results indicate that the more complex measure has
overall superior predictive accuracy, but its downside is that subjects exhibit noisier behavior. Our main result is that
subjects’ numerical skills can help better assess this tradeoff: the simpler task may be preferred for subjects who exhibit
low numeracy, as it generates less noisy behavior but similar predictive accuracy. For subjects with higher numerical skills,
the greater predictive accuracy of the more complex task more than outweighs the larger noise. We also explore preference
heterogeneity and provide methodological suggestions for future work. 相似文献

Risk assessors and managers face many difficult challenges related to novel cyber systems. Among these challenges are the constantly changing nature of cyber systems caused by technical advances, their distribution across the physical, information, and sociocognitive domains, and the complex network structures often including thousands of nodes. Here, we review probabilistic and risk-based decision-making techniques applied to cyber systems and conclude that existing approaches typically do not address all components of the risk assessment triplet (threat, vulnerability, consequence) and lack the ability to integrate across multiple domains of cyber systems to provide guidance for enhancing cybersecurity. We present a decision-analysis-based approach that quantifies threat, vulnerability, and consequences through a set of criteria designed to assess the overall utility of cybersecurity management alternatives. The proposed framework bridges the gap between risk assessment and risk management, allowing an analyst to ensure a structured and transparent process of selecting risk management alternatives. The use of this technique is illustrated for a hypothetical, but realistic, case study exemplifying the process of evaluating and ranking five cybersecurity enhancement strategies. The approach presented does not necessarily eliminate biases and subjectivity necessary for selecting countermeasures, but provides justifiable methods for selecting risk management actions consistent with stakeholder and decisionmaker values and technical data. 相似文献

As eco‐social work practice and scholarship continues to grow, multiple frameworks are emerging to help guide the work. In this study, we interviewed 59 people affected by environmental injustice. Participants identified components within both environmental injustice and sustainability, as well as gaps that these models individually do not support. Therefore, we suggest that merging environmental justice with sustainability through centering justice (a component within environmental justice), and also finding solutions through technological advances (a component within sustainability), may best support these communities. In addition, the participants discussed the need for support, which social workers can provide. 相似文献

In a national study of public charities in the United States, we find that some organizations experience little difficulty recruiting volunteers while others report substantial problems. We study which organizations are more likely to report recruitment problems, separating the underlying forces for those problems into two camps. One, which we label “nature,” represents organizational conditions that cannot readily be overcome by a management response. The other, which we label “nurture,” represents organizational conditions that volunteer resource managers and other members of the top management team can directly influence as they seek to make their organization more inviting to prospective volunteers. We find some support for both camps, concluding that managers must be prepared to work with both immutable and malleable conditions when devising strategies for recruiting volunteers whose schedule and skills fit the organization's needs. 相似文献

Regression and correlation properties of the generalized Farlie-Gumbel-Morgenstem distributions introduced in Johnson and Kotz (1975) are studied. Further generalizations of these distributions are considered. 相似文献
