Quantum stochastic integrals as operators

We construct quantum stochastic integrals for the integrator being a martingale in a von Neumann algebra, and the integrand -- a suitable process with values in the same algebra, as densely defined operators affiliated with the algebra. In the case of a finite algebra we allow the integrator to be an $L^2$--martingale in which case the integrals are $L^2$--martingales too

Servitization 2.0: The significance of product and service dominant logics for public service organisations

This conceptual paper explores servitization as significant to public service organisations (PSOs) within which there is a requirement to administer lean and sustainable provision. It specifically appreciates that the digital transformation of services has embraced customer processing machine technologies that facilitate volume growth alongside information sharing; thus, fostering co-operation within collaborative network systems whilst pro-actively operating as elements of the product-service system (PSS). It demonstrates the significance of good-dominant logic (GDL) and service-dominant logic (SDL) perspectives when considering servitization within specific PSOs, and therefore seeks to better understand the strategic and operational realities for the era of Servitization 2.0

Philosophy Without Belief

Should we believe our controversial philosophical views? Recently, several authors have argued from broadly conciliationist premises that we should not. If they are right, we philosophers face a dilemma: If we believe our views, we are irrational. If we do not, we are not sincere in holding them. This paper offers a way out, proposing an attitude we can rationally take toward our views that can support sincerity of the appropriate sort. We should arrive at our views via a certain sort of ‘insulated’ reasoning – that is, reasoning that involves setting aside certain higher-order worries, such as those provided by disagreement – when we investigate philosophical questions

Maxwellian theory of gravitational waves and their mechanical properties

We present a theory in Maxwellian form for gravitational waves in a flat background. This requires us to identify the gravitational analogues of the electric and magnetic fields for light. An important novelty, however, is that our analogues are not vector fields but rather rank-two tensor fields; in place of a three-component vector at each point in space, as in electromagnetism, our fields are three by three symmetric matrices at each point. The resulting Maxwell-like equations lead directly to a Poynting theorem for the local energy density associated with a gravitational wave and to associated local properties including densities of momentum and angular momentum

No free lunch: The significance of tiny contributions

There is a well-known moral quandary concerning how to account for the rightness or wrongness of acts that clearly contribute to some morally significant outcome – but which each seem too small, individually, to make any meaningful difference. One consequentialist-friendly response to this problem is to deny that there could ever be a case of this type. This paper pursues this general strategy, but in an unusual way. Existing arguments for the consequentialist-friendly position are sorites-style arguments. Such arguments imagine varying a subject’s predicament bit by bit until it is clear that a relevant difference has been achieved. The arguments offered in this paper are structurally different, and do not rely on any sorites series. For this reason, they are not vulnerable to objections that have been leveled against the sorites-style arguments

‘More Than Just TV’: Educational broadcasting and popular culture in South Africa

About the book: Yearbook 2002 contains research examples illustrating the role of media globalisation in children's and young people's lives in different parts of the world. The transnational media and media contents - imported television programmes, satellite TV, the Internet, video and computer games, popular music, 'global' advertising and merchandised products - are to a great extent used by children and are, as well, increasingly targeting children. What does this mean for media production? For children's cultural identity and participation in society? For digital and economic divides among children both within and between richer and poorer countries? A separate section of the book presents recent statistics on children in the world and media in the world

CLIP/CETL Fellowship Report 2007/8 : Mentorship Scheme : extending work related learning

This project seeks to work with four parties; current second year students, alumni within the design industry, design professionals and PPD staff at LCC in a two stage process; setting up the requirements for a mentorship scheme and then investigating the outcomes. A handbook and website was produced

Media transformation and new practices of citizenship: the example of environmental activism in South Durban

South African media and telecommunications have been fundamentally restructured in the last decade. Corporate unbundling and black economic empowerment have transformed the ownership of broadcasting, print media, publishing, and telecommunications; new radio and television services have been set up; the SABC has been restructured as an independent public service broadcaster; and a new independent regulatory authority for broadcasting and telecommunications has been established. However, a once vibrant alternative press, closely associated with the mass mobilisation against apartheid of the 1980s and 1990s, has suffered severe decline. New technologies, such as satellite television, the Internet, mobile telephony, and digital media have all rapidly established a foothold in South African communications markets. All of these processes have gone hand in hand with a re-scaling of South African media economies and media cultures. Inward foreign investment in South African media and communications industries has been matched by a 'continental drift' of South African capital into African media and communications markets (Barnett 1999b, Tomaselli and Dunn2001)

Resolution of the Abraham-Minkowski dilemma

The dilemma of identifying the correct form for the momentum of light in a medium has run for a century and has been informed by many distinguished contributions, both theoretical and experimental. We show that both the Abraham and Minkowski forms of the momentum density are correct, with the former being the kinetic momentum and the latter the canonical momentum. This identification allows us to explain why the experiments supporting each of the rival momenta gave the results that they did. The inclusion of dispersion and absorption provides an interesting subtlety, but does not change our conclusion
