Invariance of the distributional curvature of the cone under smooth diffeomorphisms
No full textAn explicit calculation is carried out to show that the distributional curvature of a 2-cone, calculated by Clarke et al (Clarke C J S, Vickers J A and Wilson J P 1996 Class. Quantum Grav. 13 2485-98), using Colombeau's new generalized functions is invariant under nonlinear Coo coordinate transformations

Addressing embodied inequities in health: how do we enable improvement in women's diet in pregnancy?
No full textObjective:To disrupt cycles of health inequity, traceable to dietary inequities in the earliest stages of life, public health interventions should target improving nutritional wellbeing in preconception/pregnancy environments. This requires a deep engagement with pregnant/postpartum people (PPP) and their communities (including their health and social care providers, HSCP). We sought to understand the factors that influence diet during pregnancy from the perspectives of PPP and HSCP, and to outline intervention priorities.Design:We carried out thematic network analyses of transcripts from ten focus group discussions (FGD) and one stakeholder engagement meeting with PPP and HSCP in a Canadian city. Identified themes were developed into conceptual maps, highlighting local priorities for pregnancy nutrition and intervention development.Setting:FGD and the stakeholder meeting were run in predominantly lower socioeconomic position (SEP) neighbourhoods in the sociodemographically diverse city of Hamilton, Canada.Participants:All local, comprising twenty-two lower SEP PPP and forty-three HSCP.Results:Salient themes were resilience, resources, relationships and the embodied experience of pregnancy. Both PPP and HSCP underscored that socioeconomic-political forces operating at multiple levels largely determined the availability of individual and relational resources constraining diet during pregnancy. Intervention proposals focused on cultivating individual and community resilience to improve early-life nutritional environments. Participants called for better-integrated services, greater income supports and strengthened support programmes.Conclusions:Hamilton stakeholders foregrounded social determinants of inequity as main factors influencing pregnancy diet. They further indicated a need to develop interventions that build resilience and redistribute resources at multiple levels, from the household to the state

Online Gambling: Today’s Possibilities and Tomorrow’s Opportunities
No full textWith the development of new information and communication technologies (ICT), above all computers and the internet, new forms of online commerce have emerged. The gambling industry began using the power of the rapidly developing virtual market by offering its services in online casinos. The phenomenon of online gambling has encouraged researchers to direct their work into various areas, including the characteristics or profile of online gamblers. In light of the data on the growth of the market for online gambling it is evident that, in the relation between the many types of traditional and online gambling, visits to traditional casinos predominate, as do predictions about the development of the internet. We therefore decided to examine the characteristics of gamblers in traditional casinos and to determine what percentage of them also gamble online, as well as to establish their profile. The aim of the research was to determine how their characteristics in respect of the development of the internet and the growth of the market have influenced the subsequent development of traditional and internet casinos. We predict that both types of gambling, each in its own way, will compete for gamblers. For traditional casinos the best solution seems to be opening their own online casinos; online casinos will have to remain abreast of the development of the internet and communication technology.online gambling, online casino, online gambling product
The access pricing problem: a synthesis
No full textThe Baumol-Willig efficient component pricing rule states that it is efficient to set the price of access to an essential facility equal to the direct cost of access plus the opportunity cost to the integrated access provider. The authors analyze the relevant notion of 'opportunity cost' under various assumptions about demand and supply conditions, including product differentiation, bypass, and substitution possibilities, which all reduce opportunity cost compared to the benchmark case. They show that the Ramsey approach to access pricing developed by J.-J. Laffont and J. Tirole (1994) is closely related to the efficient component pricing rule provided opportunity cost is correctly interpreted
A nonlinear theory of distributional geometry
No full textThis paper builds on the theory of nonlinear generalized functions begun in Nigsch & Vickers (Nigsch, Vickers 2021 Proc. R. Soc. A 20200640(doi:10.1098/rspa.2020.0640)) and extends this to a diffeomorphism-invariant nonlinear theory of generalized tensor fields with the sheaf property. Thegeneralized Lie derivative is introduced and shown to commute with the embedding of distributional tensor fields and the generalized covariant derivative commutes with the embedding at the level of association. The concept of a generalized metric is introduced and used to develop a non-smooththeory of differential geometry. It is shown that the embedding of a continuous metric results in a generalized metric with well-defined connection andcurvature and that for C2 metrics the embedding preserves the curvature at the level of association. Finally, we consider an example of a conical metric outside the Geroch–Traschen class and show that the curvature is associated to a delta function
