Making the Most of Mess

In Making the Most of Mess, Emery Roe emphasizes that policy messes cannot be avoided or cleaned up; they need to be managed. He shows how policymakers and other professionals can learn these necessary skills from control operators who manage large critical infrastructures such as water supplies, telecommunications systems, and electricity grids. The ways in which they prevent major accidents and failures offer models for policymakers and other professionals to manage the messes they face. Throughout, Roe focuses on the global financial mess of 2008 and its ongoing aftermath, showing how mismanagement has allowed it to morph into other national and international messes. More effective management is still possible for this and many other policy messes but that requires better recognition of patterns and formulation of scenarios, as well as the ability to translate pattern and scenario into reliability

Control, Manage or Cope?

Just as an emancipatory politics of uncertainty recognises that uncertainty and unknown-unknowns cannot be closed down to measurable risk, so too does the politics require better differentiation among controlling, managing and coping with those risks, uncertainties and the unknown-unknown of unstudied – in real-time, often unstudiable – conditions

Lessons for human survival in a world without ecological templates : what can we learn from small-scale societies?

Historical records are incomplete templates for preparing for an uncertain future. The global utility of past ecological knowledge for present/future purposes is questioned as we move from Holocene to Anthropocene. To increase the adaptive capacity of today’s societies, generalizable strategies must be identified for coping with uncertainty over a wide range of conditions and contingencies. We identify two key principles that increase adaptive capacities: diversification and precautionary heuristics. These sharply contrast with the present global state represented by the global production ecosystem characterized by: (1) homogenization and simplification of cultural practices and resource bases; (2) increased global connectivity and forced dissolution of cultural borders; and (3) centralization and intensification of modes of resource production and extraction. We highlight that responses of smaller-scale societies to risks and uncertainties are in many cases emulated by professionals in the high reliability management in today’s critical infrastructures. This provides a modern template for managing unpredictability in the Anthropocene.Peer reviewe

Supporting Child Wellbeing: a health assessment tool for the Hamilton Children’s Team

The Hamilton Children’s Team received its first referral in 2015, with dedicated lead professionals appointed for each child referred. The role of these lead professionals is to assess need, develop a plan for each child, and coordinate a cross-sector Child Action Network to improve care and wellbeing. Challenges were identified in Hamilton for the assessment, identification and coordination of health need within the Children’s Team, particularly for lead professionals from outside the health sector. Therefore, a health assessment package was developed in partnership with the Hamilton Children’s Team, the Waikato District Health Board and other relevant agencies. The use of a standardised and systematic approach, with training and relationship development, resources and referral pathways, resulted in identification of significant unmet need. A number of referrals to the health sector resulted from this assessment and there are implications that such a process can support ongoing attendance at health appointments, monitoring of outcomes from the Children’s Team process, and improvements to physical, emotional and mental wellbeing for families. This approach was well received by lead professionals and families, and future use is likely to enhance the Children’s Team programme and service delivery, and improve wellbeing outcomes

Assessment of a high-resolution central scheme for the solution of the relativistic hydrodynamics equations

We assess the suitability of a recent high-resolution central scheme developed by Kurganov & Tadmor (2000) for the solution of the relativistic hydrodynamics equations. The novelty of this approach relies on the absence of Riemann solvers in the solution procedure. The computations we present are performed in one and two spatial dimensions in Minkowski spacetime. Standard numerical experiments such as shock tubes and the relativistic flat-faced step test are performed. As an astrophysical application the article includes two-dimensional simulations of the propagation of relativistic jets using both Cartesian and cylindrical coordinates. The simulations reported clearly show the capabilities of the numerical scheme to yield satisfactory results, with an accuracy comparable to that obtained by the so-called high-resolution shock-capturing schemes based upon Riemann solvers (Godunov-type schemes), even well inside the ultrarelativistic regime. Such central scheme can be straightforwardly applied to hyperbolic systems of conservation laws for which the characteristic structure is not explicitly known, or in cases where the exact solution of the Riemann problem is prohibitively expensive to compute numerically. Finally, we present comparisons with results obtained using various Godunov-type schemes as well as with those obtained using other high-resolution central schemes which have recently been reported in the literature.Comment: 14 pages, 12 figures, to appear in A&

Runge-Kutta residual distribution schemes

We are concerned with the solution of time-dependent non-linear hyperbolic partial differential equations. We investigate the combination of residual distribution methods with a consistent mass matrix (discretisation in space) and a Runge–Kutta-type time-stepping (discretisation in time). The introduced non-linear blending procedure allows us to retain the explicit character of the time-stepping procedure. The resulting methods are second order accurate provided that both spatial and temporal approximations are. The proposed approach results in a global linear system that has to be solved at each time-step. An efficient way of solving this system is also proposed. To test and validate this new framework, we perform extensive numerical experiments on a wide variety of classical problems. An extensive numerical comparison of our approach with other multi-stage residual distribution schemes is also given
