Robust Defibrillator Deployment Under Cardiac Arrest Location Uncertainty via Row-and-Column Generation [PDF]

arXiv, 2015
Sudden cardiac arrest is a significant public health concern. Successful treatment of cardiac arrest is extremely time sensitive, and use of an automated external defibrillator (AED) where possible significantly increases the probability of survival. Placement of AEDs in public locations can improve survival by enabling bystanders to treat victims of ...

COVID‐19 and the Meaning of Crisis

Development and Change, Volume 53, Issue 6, Page 1151-1176, November 2022., 2022
ABSTRACT Crisis is a concept that has a long history; it has come to denote moments of rupture and to foreground life and death decisions necessary for its resolution. The recent deployment of the concept in broad social, economic and political spheres has not only given rise to an industry of crisis management but has also established it as a ...

Thermochemical Recycling and Degradation Strategies of Halogenated Polymers (F−, Cl−, Br−): A Holistic Review Coupled with Mechanistic Insights

The Chemical Record, EarlyView.
This review aims to comprehensively address recent degradation techniques (physical, chemical and biological) of halogenated waste polymers with a prime focus on thermal degradation techniques. Exploiting various metal oxides during co‐pyrolysis is deemed a viable solution for recycling halogenated polymeric waste.

Contesting the crisis narrative: epidemic accounts in Sierra Leone, Tanzania, and Democratic Republic of the Congo

Disasters, Volume 47, Issue 1, Page 78-98, January 2023., 2023
Scientists and global commentators watched African countries closely in the early months of the COVID‐19 pandemic, predicting an impending disaster: the virus was projected to overwhelm already weak health systems. These expectations were informed by imaginaries of Africa as an inevitable site of epidemic disaster.

Biological Flora of Britain and Ireland: Cytisus scoparius*

Journal of Ecology, EarlyView.
Broom is an attractive and common native plant across Britain, Ireland and most of Europe, and yet it is considered a harmful and invasive weed around the rest of the world. This is aided by broom thriving on poor dry soils, helped by using green stems for photosynthesis and having root nodules to fix nitrogen.

Driver Surge Pricing [PDF]

arXiv, 2019
Ride-hailing marketplaces like Uber and Lyft use dynamic pricing, often called surge, to balance the supply of available drivers with the demand for rides. We study driver-side payment mechanisms for such marketplaces, presenting the theoretical foundation that has informed the design of Uber's new additive driver surge mechanism.
