Quantum Theory: a Pragmatist Approach
While its applications have made quantum theory arguably the most successful
theory in physics, its interpretation continues to be the subject of lively
debate within the community of physicists and philosophers concerned with
conceptual foundations. This situation poses a problem for a pragmatist for
whom meaning derives from use. While disputes about how to use quantum theory
have arisen from time to time, they have typically been quickly resolved, and
consensus reached, within the relevant scientific sub-community. Yet rival
accounts of the meaning of quantum theory continue to proliferate . In this
article I offer a diagnosis of this situation and outline a pragmatist solution
to the problem it poses, leaving further details for subsequent articles

Domain Tasting Is Taking Over the Internet as a Result of ICANNâs âAdd Grace Periodâ
When a domain name is registered, the registrant is given five days to cancel for a full refund. While the purpose of this grace period is to protect those who innocently err in the registration process, speculators have taken advantage of the grace period through a process called domain tasting. These domain tasters register hundreds of thousands of domain names and cancel the vast majority of them within the five-day grace period, keeping only those that may be valuable as placeholder advertising websites or to holders of trademark rights. This iBrief will outline the domain tasting process, analyze why it is a problem, and discuss solutions to the problem. Ultimately, it concludes that the five-day grace period is unnecessary because it serves little, if any, legitimate purpose
Observation and Quantum Objectivity
The paradox of Wigner's friend challenges the objectivity of description in
quantum theory. A pragmatist interpretation can meet this challenge by
judicious appeal to decoherence. On this interpretation, quantum theory
provides situated agents with resources for predicting and explaining what
happens in the physical world---not conscious observations of it. Even in
Wigner's friend scenarios, differently situated agents agree on the objective
content of statements about the values of physical magnitudes. In more
realistic circumstances quantum Darwinism also permits differently situated
agents equal observational access to evaluate their truth. In this view,
quantum theory has nothing to say about consciousness or conscious experiences
of observers. But it does prompt us to reexamine the significance even of
everyday claims about the physical world
Quantum decoherence in a pragmatist view: Resolving the measurement problem
This paper aims to show how adoption of a pragmatist interpretation permits a satisfactory resolution of the quantum measurement problem. The classic measurement problem dissolves once one recognizes that it is not the function of the quantum state to describe or represent the behavior of a quantum system. The residual problem of when, and to what, to apply the Born Rule may then be resolved by judicious appeal to decoherence. This can give sense to talk of measurements of photons and other particles even though quantum field theory does not describe particles
When is an international branch campus?
For a Nottingham alumnus, driving onto the University of Nottinghamâs branch campus in Malaysia is a surreal experience. Surrounded by tropical rainforest, a familiar white silhouette emergesâa clock tower atop the signature Trent Building, overlooking a large lake. Despite the heat and humidity, the campus at Semenyih looks and feels like an extension of the University of Nottingham, reinforcing its "one university, three campuses" (United Kingdom, Malaysia and China) branding

Is UK transnational education 'one of Britain's great growth industries of the future'?
Against the backdrop of unprecedented growth in the global demand for higher education, the UK government has recognised that there is a huge potential market beyond conventional âexport education â, if its universities can find ways of providing âtransnational educationâ (TNE) to the millions of foreign students unable or unwilling to travel to the UK. This paper tests the thesis that TNE represents âone of Britainâs great growth industries of the futureâ. For TNE to flourish, three conditions need to be satisfied, namely: that there is already a strong base of UK TNE activity and expertise on which to build; second, that there will be continuing growth in demand for UK TNE; and finally, that UK universities have the capability and willingness to expand supply to meet any future growth in demand. It finds little evidence to support the thesis that TNE is, in fact, likely to be a great growth industry and highlights the dangers for policymakers of setting objectives in the absence of a strong evidence base about current capabilities and future market trends
