Pivot to Telehealth: Narrative Reflections on Circle of Security Parenting Groups during COVID‐19

In response to COVID‐19 hygiene and physical distancing restrictions, our service rapidly shifted to delivering Circle of Security‐Parenting? (COS‐P) groups via telehealth. In this article we report the perspectives and experiences of the group facilitator and the parents who received the intervention during the COVID‐19 pandemic. We use semi‐structured, qualitative interviews to explore the advantages, challenges, and positive impacts of the online parenting group from the perspectives of the group leader and the five group participants. Participants’ narrative reflections show that they were satisfied with the convenient and engaging online delivery of the program and would recommend it to other parents. Parents reported significant improvements in their parenting and greater awareness of their strengths and struggles. The online delivery of COS‐P resulted in more efficient service delivery, greater attendance rates, and adherence to the model. The stressors on the experienced facilitator, due to the abrupt transition and multiple technical and communication challenges, may have been mitigated by supervisor and collegial support, as well as careful preparation for herself and the participants. Future research should investigate the effectiveness of online versus face‐to‐face delivery of the intervention, including what works for whom.     

Communicating Geographical Risks in Crisis Management: The Need for Research

In any crisis, there is a great deal of uncertainty, often geographical uncertainty or, more precisely, spatiotemporal uncertainty. Examples include the spread of contamination from an industrial accident, drifting volcanic ash, and the path of a hurricane. Estimating spatiotemporal probabilities is usually a difficult task, but that is not our primary concern. Rather, we ask how analysts can communicate spatiotemporal uncertainty to those handling the crisis. We comment on the somewhat limited literature on the representation of spatial uncertainty on maps. We note that many cognitive issues arise and that the potential for confusion is high. We note that in the early stages of handling a crisis, the uncertainties involved may be deep, i.e., difficult or impossible to quantify in the time available. In such circumstance, we suggest the idea of presenting multiple scenarios.     

Systemic risk statistics with scenario analysis

In this paper, we introduce two new classes of risk statistics, named convex and positively homogeneous systemic risk statistics, respectively. Structural decomposition results and representation results for them are provided. These new risk statistics can be considered as a kind of systemic risk extension of risk statistics introduced by Kou, Peng, and Heyde, and also empirical versions of system risk measures introduced by Cehn, Iyengar, and Mollemi and Kromer, Overbeck, and Zich. Finally, some examples are also given.     

An overview of evidence-based program registers (EBPRs) for behavioral health

Evaluations of behavioral health interventions have identified many that are potentially effective. However, clinicians and other decision makers typically lack the time and ability to effectively search and synthesize the relevant research literature. In response to this opportunity, and to increasing policy and funding pressures for the use of evidence-based practices, a number of “what works” websites have emerged to assist decision makers in selecting interventions with the highest probability of benefit. However, these registers as a whole are not well understood. This article, which represents phase one of a concurrent mixed methods study, presents a review of the scopes, structures, dissemination strategies, uses, and challenges faced by evidence-based registers in the behavioral health disciplines. The major findings of this study show that in general, registers of evidence-based practices are able, to a degree, to identify the most effective practices meet this need to a degree. However, much needs to be done to improve the ability of the registers to fully realize their purpose.     

The Multiscale Importance of Road Segments in a Network Disruption Scenario: A Risk‐Based Approach

This article addresses the problem of the multiscale importance of road networks, with the aim of helping to establish a more resilient network in the event of a road disruption scenario. A new model for identifying the most important roads is described and applied on a local and regional scale. The work presented here represents a step forward, since it focuses on the interaction between identifying the most important roads in a network that connect people and health services, the specificity of the natural hazards that threaten the normal functioning of the network, and an assessment of the consequences of three real‐world interruptions from a multiscale perspective. The case studies concern three different past events: road interruptions due to a flood, a forest fire, and a mass movement. On the basis of the results obtained, it is possible to establish the roads for which risk management should be a priority. The multiscale perspective shows that in a road interruption the regional system may have the capacity to reorganize itself, although the interruption may have consequences for local dynamics. Coordination between local and regional scales is therefore important. The model proposed here allows for the scaling of emergency response facilities and human and physical resources. It represents an innovative approach to defining priorities, not only in the prevention phase but also in terms of the response to natural disasters, such as awareness of the consequences of road disruption for the rescue services sent out to local communities.

Is There a Curse of Dimensionality for Contraction Fixed Points in the Worst Case?

This paper analyzes the complexity of the contraction fixed point problem: compute an ε‐approximation to the fixed point V*Γ(V*) of a contraction mapping Γ that maps a Banach space B_d of continuous functions of d variables into itself. We focus on quasi linear contractions where Γ is a nonlinear functional of a finite number of conditional expectation operators. This class includes contractive Fredholm integral equations that arise in asset pricing applications and the contractive Bellman equation from dynamic programming. In the absence of further restrictions on the domain of Γ, the quasi linear fixed point problem is subject to the curse of dimensionality, i.e., in the worst case the minimal number of function evaluations and arithmetic operations required to compute an ε‐approximation to a fixed point V*∈B_d increases exponentially in d. We show that the curse of dimensionality disappears if the domain of Γ has additional special structure. We identify a particular type of special structure for which the problem is strongly tractable even in the worst case, i.e., the number of function evaluations and arithmetic operations needed to compute an ε‐approximation of V* is bounded by Cε^−p where C and p are constants independent of d. We present examples of economic problems that have this type of special structure including a class of rational expectations asset pricing problems for which the optimal exponent p1 is nearly achieved.
