The Yew Disaster Severity Index: A New Tool in Disaster Metrics.

Objectives: The Richter Scale measures the magnitude of a seismic occurrence, but it does not feasibly quantify the magnitude of the "disaster" at the point of impact in real humanitarian needs, based on United Nations International Strategy for Disaster Reduction (UNISDR; Geneva, Switzerland) 2009 Disaster Terminology. A Disaster Severity Index (DSI) similar to the Richter Scale and the Mercalli Scale has been formulated; this will quantify needs, holistically and objectively, in the hands of any stakeholders and even across timelines.

Background: An agreed terminology in quantifying "disaster" matters; inconsistency in measuring it by stakeholders posed a challenge globally in formulating legislation and policies responding to it.

Converging and emerging threats to health security.

Advances in biological sciences have outpaced regulatory and legal frameworks for biosecurity. Simultaneously, there has been a convergence of scientific disciplines such as synthetic biology, data science, advanced computing and many other technologies, which all have applications in health. For example, advances in cybercrime methods have created ransomware attacks on hospitals, which can cripple health systems and threaten human life.

Publicly available software tools for decision-makers during an emergent epidemic-Systematic evaluation of utility and usability.

Epidemics and emerging infectious diseases are becoming an increasing threat to global populations-challenging public health practitioners, decision makers and researchers to plan, prepare, identify and respond to outbreaks in near real-timeframes. The aim of this research is to evaluate the range of public domain and freely available software epidemic modelling tools. Twenty freely utilisable software tools underwent assessment of software usability, utility and key functionalities.
