Tiered Approach to Resilience Assessment

Regulatory agencies have long adopted a three‐tier framework for risk assessment. We build on this structure to propose a tiered approach for resilience assessment that can be integrated into the existing regulatory processes. Comprehensive approaches to assessing resilience at appropriate and operational scales, reconciling analytical complexity as needed with stakeholder needs and resources available, and ultimately creating actionable recommendations to enhance resilience are still lacking. Our proposed framework consists of tiers by which analysts can select resilience assessment and decision support tools to inform associated management actions relative to the scope and urgency of the risk and the capacity of resource managers to improve system resilience. The resilience management framework proposed is not intended to supplant either risk management or the many existing efforts of resilience quantification method development, but instead provide a guide to selecting tools that are appropriate for the given analytic need. The goal of this tiered approach is to intentionally parallel the tiered approach used in regulatory contexts so that resilience assessment might be more easily and quickly integrated into existing structures and with existing policies.     

Availability analysis for general repairable systems with repair time threshold

Availability analysis is an important issue in many practical fields. This paper investigates the availability for general repairable systems with repair time threshold. Based on practical applications, a repair time threshold is introduced. If the period of a repair is less than a predefined time threshold, then the system may be considered as working during this period, i.e., the effect of the repair could be neglected. Otherwise, if the period of a repair is longer than the given threshold, then the system is considered as working from the beginning of the system failure until the repair time exceeding the threshold, i.e., the time point of the system down could be delayed. We consider both constant and random repair time threshold. This paper valuates the user-perceived availability, when the user does not experience any service interruption because the duration of repair is too short. The results can be applied in reliability engineering, queueing theory and many other fields. A numerical example for ventilator system is presented to demonstrate the application of the developed approach.     

Wider Perspectives in Family Mediation: An Ecosystemic Approach

All mediation processes are constrained by their theoretical frameworks. A wider ecosystemic framework extends perspectives and can open new windows on family systems, interdisciplinary connections, and links between past, present, and future that shape decisions. While showing some similarities to family therapy, ecosystemic family mediation is a discrete process with clearly defined principles and boundaries. In practice, it needs to be tailored to the needs of the particular family, with special attention to the importance of listening and talking with children who are experiencing parental separation and major changes in their lives. Family mediators help family members to manage change. Mediators need to look for change within themselves too, remaining open to new ideas and the development of their thinking and practice.     

Scholarly Communications Training: Professional Development for the Next Generation of Scholars

Abstract

Many campuses are seeing increased needs for support in scholarly communications areas such as open access, research identity management, scholarship metrics, and related topics. This article discusses a professional development program that addresses scholarly communications needs for online and in-person graduate students and faculty at UNC Greensboro (UNCG), through a collaborative, interdepartmental effort that brings together librarians from the departments of Research, Outreach, and Instruction (ROI) and Technical Services. The authors provide a brief overview of the literature related to scholarly communications needs and training in academic libraries and discuss the UNCG program’s inception, modules, format, assessment, and future directions.     

We are not walking wave functions. A response to “Quantum Mind and Social Science” by Alexander Wendt

Alexander Wendt raises many interesting questions in this book, but to get to the answers he wants, he relies on a misunderstanding of the nature of the quantum states of macroscopic objects.     

GIS‐Based Integration of Social Vulnerability and Level 3 Probabilistic Risk Assessment to Advance Emergency Preparedness,Planning, and Response for Severe Nuclear Power Plant Accidents

In the nuclear power industry, Level 3 probabilistic risk assessment (PRA) is used to estimate damage to public health and the environment if a severe accident leads to large radiological release. Current Level 3 PRA does not have an explicit inclusion of social factors and, therefore, it is not possible to perform importance ranking of social factors for risk‐informing emergency preparedness, planning, and response (EPPR). This article offers a methodology for adapting the concept of social vulnerability, commonly used in natural hazard research, in the context of a severe nuclear power plant accident. The methodology has four steps: (1) calculating a hazard‐independent social vulnerability index for the local population; (2) developing a location‐specific representation of the maximum radiological hazard estimated from current Level 3 PRA, in a geographic information system (GIS) environment; (3) developing a GIS‐based socio‐technical risk map by combining the social vulnerability index and the location‐specific radiological hazard; and (4) conducting a risk importance measure analysis to rank the criticality of social factors based on their contribution to the socio‐technical risk. The methodology is applied using results from the 2012 Surry Power Station state‐of‐the‐art reactor consequence analysis. A radiological hazard model is generated from MELCOR accident consequence code system, translated into a GIS environment, and combined with the Center for Disease Control social vulnerability index (SVI). This research creates an opportunity to explicitly consider and rank the criticality of location‐specific SVI themes based on their influence on risk, providing input for EPPR.     

Portfolio Analysis of Layered Security Measures

Layered defenses are necessary for protecting the public from terrorist attacks. Designing a system of such defensive measures requires consideration of the interaction of these countermeasures. In this article, we present an analysis of a layered security system within the lower Manhattan area. It shows how portfolios of security measures can be evaluated through portfolio decision analysis. Consideration is given to the total benefits and costs of the system. Portfolio diagrams are created that help communicate alternatives among stakeholders who have differing views on the tradeoffs between security and economic activity.     

Dependence and uncertainty in broker strategies of research intermediaries

This study examines how a research intermediary can successfully manage collaboration among research partners, while mitigating resource dependence in multi-partner programs. For that purpose, two fundamentally different strategies are explored: tertius gaudens and tertius iungens. Previous literature has not addressed the possibility that the effective deployment of tertius broker strategies may be contingent on multiple factors. Using a qualitative in-depth case study, we contribute to the literature by showing that the effective development of the tertius broker strategies in our study context is contingent on partner type, business integration and product readiness.     

Human Agency in Disaster Planning: A Systems Approach

Current approaches to risk management place insufficient emphasis on the system knowledge available to the assessor, particularly in respect of the dynamic behavior of the system under threat, the role of human agents (HAs), and the knowledge available to those agents. In this article, we address the second of these issues. We are concerned with a class of systems containing HAs playing a variety of roles as significant system elements—as decisionmakers, cognitive agents, or implementers—that is, human activity systems. Within this family of HAS, we focus on safety and mission‐critical systems, referring to this subclass as critical human activity systems (CHASs). Identification of the role and contribution of these human elements to a system is a nontrivial problem whether in an engineering context, or, as is the case here, in a wider social and public context. Frequently, they are treated as standing apart from the system in design or policy terms. Regardless of the process of policy definition followed, analysis of the risk and threats to such a CHAS requires a holistic approach, since the effect of undesirable, uninformed, or erroneous actions on the part of the human elements is both potentially significant to the system output and inextricably bound together with the nonhuman elements of the system. We present a procedure for identifying the potential threats and risks emerging from the roles and activity of those HAs, using the 2014 flooding in southwestern England and the Thames Valley as a contemporary example.     

The need for improved emotional support: A pilot online survey of Australian women’s access to healthcare services and support at the time of miscarriage

ProblemWomen need improved emotional support from healthcare professionals following miscarriage.BackgroundSignificant psychological morbidity can result following miscarriage and may be exacerbated by poor support experiences. Women frequently report high levels of dissatisfaction with healthcare support at this time.AimThis study was developed to pilot a survey aimed at exploring women’s access to healthcare services and support at the time of miscarriage.MethodsWomen over 18 years, residing in Australia, who had experienced a miscarriage in the past two years completed a 29-item online survey.FindingsA total of 399 women completed the survey. Two key findings arose: 1) More than half of women (59%) were not offered any information about miscarriage or pregnancy loss support organisations or referral/access to counselling services at the time of miscarriage, despite almost all reporting they would have liked various forms of support from items listed 2) More than half (57%) did not receive follow up care, or emotional support at this time, beyond being asked how they were coping emotionally. Other findings showed 3) Women accessed various healthcare services at the time of miscarriage and 4) Women often saw a general practitioner at the time of miscarriage despite having a private obstetrician.ConclusionThere is clear mismatch between the support women want at the time of miscarriage and the care they receive from healthcare professionals. Despite considerable structural barriers, it seems likely there is scope within healthcare professionals’ usual practice for improved support care through simple measures such as increased acknowledgement, information provision and referral to existing support services.
