End-User-Oriented Telco Mashups: The OMELETTE Approach

With the success of Web 2.0 we are witnessing a growing number of services and APIs exposed by Telecom, IT and content providers. Targeting the Web community and, in particular, Web application developers, service providers expose capabilities of their infrastructures and applications in order to open new markets and to reach new customer groups. However, due to the complexity of the underlying technologies, the last step, i.e., the consumption and integration of the offered services, is a non-trivial and time-consuming task that is still a prerogative of expert developers. Although many approaches to lower the entry barriers for end users exist, little success has been achieved so far. In this paper, we introduce the OMELETTE project and show how it addresses end-user-oriented telco mashup development. We present the goals of the project, describe its contributions, summarize current results, and describe current and future work

Notes on Cloud computing principles

This letter provides a review of fundamental distributed systems and economic Cloud computing principles. These principles are frequently deployed in their respective fields, but their inter-dependencies are often neglected. Given that Cloud Computing first and foremost is a new business model, a new model to sell computational resources, the understanding of these concepts is facilitated by treating them in unison. Here, we review some of the most important concepts and how they relate to each other

Mashup indices of development

Countries are increasingly being ranked by some new"mashup index of development,"defined as a composite index for which existing theory and practice provides little or no guidance to its design. Thus the index has an unusually large number of moving parts, which the producer is essentially free to set. The parsimony of these indices is often appealing -- collapsing multiple dimensions into just one, yielding unambiguous country rankings, and possibly reducing concerns about measurement errors in the component series. But the meaning, interpretation and robustness of these indices are often unclear. If they are to be properly understood and used, more attention needs to be given to their conceptual foundations, the tradeoffs they embody, the contextual factors relevant to country performance, and the sensitivity of the implied rankings to changing the data and weights. In short, clearer warning signs are needed for users. But even then, nagging doubts remain about the value-added of mashup indices, and their policy relevance, relative to the"dashboard"alternative of monitoring the components separately. Future progress in devising useful new composite indices of development will require that theory catches up with measurement practice.Economic Theory&Research,Information Security&Privacy,Governance Indicators,Health Monitoring&Evaluation,Debt Markets

Participatory GIS in design of the Wroclaw University of Science and Technology campus web map and spatial analysis of campus area quality

Public participation geographic information system (GIS) and participatory mapping data collection methods are means that enhance capacity in generating, managing, and communicating spatial information in various fields ranging from local planning to environmental management. In this study these methods have been used in two ways. The first one, to gather information on the additional functionality of campus web map expected by its potential users, i.e. students, staff and visitors, through web based survey. The second, to collect geographically referenced information on campus areas that are liked and disliked in a geo-survey carried out with ArcGIS Online GeoForm Application. The results of the first survey were used to map facilities such as: bicycle infrastructure, building entrances, wheelchair accessible infrastructure and benches. The results of the second one, to analyse the most and the least attractive parts of the campus with heat and hot spot analyses in GIS. In addition, the answers have been studied with regard to the visual and functional aspects of campus area raised in the survey. The thematic layers developed in the results of field mapping and geoprocessing of geosurvey data were included in the campus web map project. The paper describes the applied methodology of data collection, processing, analysis, interpretation and geovisualisation

Value Creation through Co-Opetition in Service Networks

Well-defined interfaces and standardization allow for the composition of single Web services into value-added complex services. Such complex Web Services are increasingly traded via agile marketplaces, facilitating flexible recombination of service modules to meet heterogeneous customer demands. In order to coordinate participants, this work introduces a mechanism design approach - the co-opetition mechanism - that is tailored to requirements imposed by a networked and co-opetitive environment

A comparative case study: Examining the organizational use of social networking sites

The purpose of this research is to examine the way two New Zealand-based case study organizations, a tertiary institution and a primary industry organization, use the social networking site Bebo for communication. Both organizations recruited young people aged 16-19, to work in the primary industry and to attend the tertiary institution. This interpretive, qualitative comparative case study identifies why each organization decided to use Bebo, what it intended to achieve, whether Bebo helped each organization to achieve its goals and objectives, and the challenges and opportunities for developing authentic and interactive dialogue faced by each organization with its intended public. Interviews were conducted with organizational members and spokespeople involved in each campaign. A critical discourse analysis is applied to all transcripts and the Bebo profiles. Other relevant organizational documents, including press releases and information brochures, provide contextual information for the analysis. The findings indicate that both organizations have been misled by a taken-for-granted assumption about young people's use of the social networking site Bebo, with the research raising questions about whether the campaign reached the target audience or not. Other findings highlight that the tertiary institution reframed the social media-influenced understanding of 'engagement', from a two-way collaborative interaction between an organization and its publics, to a one-way, direct marketing effort by the organization. Questions are raised about the tertiary institutions use of Bebo as a marketing tool and harvesting users' personal information through a quiz. Findings indicate that both organizations were concerned about threats to their reputation, choosing to monitor both the comments left on the spokespeople's profiles by Bebo users, and the spokespeople's behaviour on Bebo. Evaluating success is identified as a challenge for both organizations, as well as issues associated with the production and distribution of the campaigns on Bebo. The findings identify opportunities for future research, to help organizations navigate the uncertainty associated with using social media applications and technologies for public relations and organizational communication. The research also highlights opportunities for other organizations to improve on the case study organizations' current use of the social networking site Bebo, to ensure future use of the application embodies dialogue, interaction and collaboration between the organizations and their target publics
