K-stability of constant scalar curvature K\"ahler manifolds

We show that a polarised manifold with a constant scalar curvature K\"ahler metric and discrete automorphisms is K-stable. This refines the K-semistability proved by S. K. Donaldson.Comment: 14 page

The Monge-Amp\`ere operator and geodesics in the space of K\"ahler potentials

It is shown that geodesics in the space of K\"ahler potentials can be uniformly approximated by geodesics in the spaces of Bergman metrics. Two important tools in the proof are the Tian-Yau-Zelditch approximation theorem for K\"ahler potentials and the pluripotential theory of Bedford-Taylor, suitably adapted to K\"ahler manifolds.Comment: 25 pages, no figure, minor misprints correcte

Contingent Valuation of Competing Public Sector Programmes: An Experiment of Single versus Joint Evaluation

In this paper, we compare single and joint evaluation (JE) of competing public sector programmes in a contingent valuation exercise. Using survey data aimed at evaluating WTP for cancer interventions (n = 2628), we disantangle two types of effects of JE: informational effects and sequence effects. By the former, wemean: by presenting different programmes to respondents, they will acquire more information on each programme than they would if each programme was valued in isolation. Sequence effects are underisable and induced by the JE exercise itself: changing the order of the valuation sequence induces different WTP values.Our results show that there are informational effects but no sequence effects. We therefore argue that JE approaches can be added to the armoury of techniques aimed at designing better survey instruments in a way that induces informational effects without incurring problems of sequencing.Single Evaluation; Joint Evaluation Willingness to Pay; Contingent Valuation; Priorities Setting

Particle and Fibre Toxicology, a new journal to meet a real need

This Editorial is to announce Particle and Fibre Toxicology, a new Open Access, peer-reviewed, online journal published by BioMed Central. The field of particle and fibre toxicology has a long and famous history stretching from Agricola and Paracelsus in the 15th and 16th century to the challenges of the 21st century-nanoparticles, nanotubes and particulate matter (PM10) to name just three. Throughout this time there has been no single journal dedicated to the toxicology of particles and fibres and this is finally corrected by the launch of Particle and Fibre Toxicology. The rationale for Particle and Fibre Toxicology rests on this need for a single multi-disciplinary journal that can cover all research relevant to particle and fibre toxicology, from Hygiene studies, through particle generation and characterisation, to animal, cell and human toxicology studies, dosimetry and modelling. The editorial also deals with the philosophy and practicalities of Open Access publishing, the journal's peer-review policy and conflict-of-interest. Particle and Fibre Toxicology is aimed at bringing together multi-disciplinary research findings towards a better understanding of how particles and fibres adversely affect the lungs and the body generally. We hope that the launch of the new journal will aid in the advance of this important discipline to the greater benefit of occupational and public health and invite scientists working in this key discipline to submit their research

An Assessment of Mobile Consumer Interest in Jamaica: Preempting a Decline in Average Revenue per User

The high density of mobile devices within the Jamaican market is seen as a precursor to a decline in average revenue per user (ARPU) in the local industry and is the primary motivation for this investigation of mobile consumers’ interest. A quantitative research was carried out in a metropolitan area to assess consumers’ interest in proposed data services to be introduced to the Jamaican mobile market and to determine the value-added properties of services that are mostly desired. The findings show that an online mobile learning game, previewing music from local artist and movies from the cinema were identified as the top three desired data services. Also, mobile applications which offer a combination of the mobile values: spontaneous needs, entertainment needs and efficiency ambitious are possible the areas of interest. The result of the research has implications for the local\regional telecommunications industry by providing recommendations on alternative services to voice

A Design Science Approach for Creating Mobile Applications

In addressing competition, telecommunications operators are faced with the challenge of creating products that lure customers from their competitors and keeping their existing customers. Researchers posit that the successful implementation and wide scale adoption of mobile commerce services is best achieved by understanding consumers’ attitude, interests and needs. The purpose of this study is to utilize the design science paradigm to address the creation of a mobile valueadded service that meet the need of consumers and to evaluate the said service for its suitability and potential adoption in Jamaica using the Technology Acceptance Model. The results suggest that consumer interest is driven by events that are related to social experiences. The evaluation of the artifact highlighted that perceived ease of use, perceived usefulness, attitude and demographic variables, age and gender, play a role in the behaviour intention to adopt the service
