Upscaling in the sharing economy: insights from the UK

Aimed at academics, private businesses, investors and public sector bodies, this report develops a typology of upscaling models in the sharing economy across three key sectors: accommodation, transportation, and professional and personal services

"Whose data is it anyway?" The implications of putting small area-level health and social data online

International audienceThe planetary exospheres are poorly known in their outer parts, since the neutral densities are low compared with the instruments detection capabilities. The exospheric models are thus often the main source of information at such high altitudes. We present a new way to take into account analytically the additional effect of the radiation pressure on planetary exospheres. In a series of papers, we present with an Hamiltonian approach the effect of the radiation pressure on dynamical trajectories, density profiles and escaping thermal flux. Our work is a generalization of the study by Bishop and Chamberlain (1989). In this second part of our work, we present here the density profiles of atomic Hydrogen in planetary exospheres subject to the radiation pressure. We first provide the altitude profiles of ballistic particles (the dominant exospheric population in most cases), which exhibit strong asymmetries that explain the known geotail phenomenon at Earth. The radiation pressure strongly enhances the densities compared with the pure gravity case (i.e. the Chamberlain profiles), in particular at noon and midnight. We finally show the existence of an exopause that appears naturally as the external limit for bounded particles, above which all particles are escaping

Enabling sharing and reuse of scientific data

The purpose of this study was to develop an understanding of the current state of scientific data sharing that stakeholders could use to develop and implement effective data sharing strategies and policies. The study developed a conceptual model to describe the process of data sharing, and the drivers, barriers, and enablers that determine stakeholder engagement. The conceptual model was used as a framework to structure discussions and interviews with key members of all stakeholder groups. Analysis of data obtained from interviewees identified a number of themes that highlight key requirements for the development of a mature data sharing culture

The Importance of Place in Corporate Identity an Investigation on the Presence of Old Dutch Firms on the Internet

This paper investigates how old Dutch firms display their corporate identity on the Internet, with special attention paid to location and place. Several scholars argue that the Internet would create the ‘end-of-geography’. Current empirical investigation found that incumbent firms display a strong sense-of-place in the presentation of ‘self’ on their websites. Location is important for old firms' images, underlining the importance of embeddedness. Location remains important when firms compete on the ‘global level’ on the Internet. This paper therefore contributes to the understanding of place and local embeddedness of firms in the ‘global internet space’

Social media data in tourism planning: Analysing tourists satisfaction in space and time.

Social media are playing an increasingly important role as information resource in tourism both for customers (i.e. the tourists), who gather trustworthy information supporting the choice of destinations and services from peers, and for businesses, which can use the same information for improving their marketing strategies. The use of social media data can also offer new opportunities for decision- support in tourism planning. With improved understanding of the motivations of tourists and tailoring tourism service supply, decision making can be facilitated by emphasizing the strengths of tourist destinations for past and potential visitors. However, this kind of information about tourists perceptions and opinions is not always properly analysed by planners. Understanding the user satisfaction, which depend on factors related to both the location and the services that the local industry propose, may offers valuable information in tourism planning at regional and local level. In the light of the above premises, the goal of the study presented in this paper is to propose an integrated approach to investigate the relationships between tourists satisfaction, destination resources and tourism industry for supporting design and decision-making in regional tourism planning. The methodology developed in the study includes data collection from popular tourism social media platforms (i.e. Booking.com and TripAdvisor.com.com), and their integration with territorial and tourism data. Spatial and statistical analysis techniques are then applied to elicit insights from tourists perceptions on success factors which may be used in decision-making and planning support. The case study demonstrates the value of social media data and computational social science techniques in tourism planning. The paper concludes with a critical discussion on the potential of using such an approach in more general urban and regional planning setting

The Portuguese urban system: An opposition between its hierarchical organization in cyberspace vs. physical space

The advent of computer and information technologies during the past decades, and their widespread use, is radically transforming the dynamics of communication and our understanding of spatial relationships. This empirical analysis intends to question how this kind of technological changes affect past trends in urban and regional development, specifically if they have enough potential to generate substantial adjustments on traditional Portuguese urban hierarchy, or instead, if it is an unexpected contribute to reinforce territorial disintegration tendencies. We analyse some geographic measurements of internet ownership, especially the density of .pt domains and the presence of each Portuguese city in the most used web search engines, in order to verify the plasticity of space throughout Portugal by the growing use of ICT’s, and the ways it has been stretched or compressed. The findings of this study suggest that the role of ICTs in the struggle against spatial inequalities in Portugal is less relevant than expected.(undefined
