Beyond Wildlife Crime: Towards The Concept Of ‘Mundane Fauna Crime’, Orlando Goodall Dec 2020

Beyond Wildlife Crime: Towards The Concept Of ‘Mundane Fauna Crime’, Orlando Goodall

School of Law, Humanities and Social Sciences

Research and theorisation on crimes against non-human species in rural regions have been conducted with less conceptual refinement than crimes against anthropocentric victims. The dominant conception of ‘wildlife crime’ predominantly advanced by the rational choice school of criminology is a nebulous ‘chaotic concept’. This article disaggregates crimes against common and relatively abundant species from that capacious categorisation and offers the original concept of ‘mundane fauna crime’ as a more precise alternative. The original concept aims to supersede the wildlife crime terminology using realist social relations theory and to offer researchers a rational abstraction to advance aetiological explanations. The additional category …

Right To Health In Gats: Can The Public Health Exception Pave The Way For Complementarity?, Swati Gola Dec 2020

Right To Health In Gats: Can The Public Health Exception Pave The Way For Complementarity?, Swati Gola

Pace International Law Review

This paper demonstrates how a right to health approach in the interpretation of the public health exception outlined in GATS Article XIV(b) can bring about a harmonious application of international human rights and international trade law regimes. Focusing on the interpretive value of the right to health for the public health exception in GATS, it examines whether a WTO Member, who has committed itself under GATS to fully liberalize all service sectors that have implications for health (e.g., hospital and other healthcare services), still retains the regulatory space to undertake measures to fulfill their right to health obligations and can …

An Australian Conundrum: Genomic Technology, Data, And The Covidsafe App, David Morrison, Patrick T. Quirk Dec 2020

An Australian Conundrum: Genomic Technology, Data, And The Covidsafe App, David Morrison, Patrick T. Quirk

Pace International Law Review

This paper examines the difficulties that have arisen in Australia in the use of its contact-tracing app. We examine the privacy implications around the use of the app, the wider economic imperative, and the balancing of those concerns against the health threat of the COVID-19 pandemic. We posit that default options are superior in times of emergency and rather than begging for the adoption of lifesaving technology, we suggest that the evidence gathered by behavioral economists provides an apposite and powerful alternative worthy of consideration.
