Realizing an Applied Gaming Ecosystem: Towards Supporting Service-based Innovation Knowledge Management and Transfer

The EU-based industry for non-leisure games is an emerging business. As such it is still fragmented and needs to achieve critical mass to compete globally. Nevertheless its growth potential is widely recognized. To become competitive the relevant applied gaming communities and SMEs require support by fostering the generation of innovation potential. The European project Realizing an Applied Gaming Ecosystem (RAGE) is aiming at supporting this challenge. RAGE will help by making available an interoperable set of advanced technology assets, tuned to applied gaming, as well as proven practices of using asset-based applied games in various real-world contexts, and finally a centralized access to a wide range of applied gaming software modules, services and related document, media, and educational resources within an online community portal called the RAGE Ecosystem. It is based on an integrational, user-centered approach of Knowledge Management and Innovation Processes in the shape of a service-based implementation.

Putting meaning into NETMAR – the open service network for marine environmental data

The open service network for marine environmental data (NETMAR) project uses semantic web technologies in its pilot system which aims to allow users to search, download and integrate satellite, in situ and model data from open ocean and coastal areas. The semantic web is an extension of the fundamental ideas of the World Wide Web, building a web of data through annotation of metadata and data with hyperlinked resources. Within the framework of the NETMAR project, an interconnected semantic web resource was developed to aid in data and web service discovery and to validate Open Geospatial Consortium Web Processing Service orchestration. A second semantic resource was developed to support interoperability of coastal web atlases across jurisdictional boundaries. This paper outlines the approach taken to producing the resource registry used within the NETMAR project and demonstrates the use of these semantic resources to support user interactions with systems. Such interconnected semantic resources allow the increased ability to share and disseminate data through the facilitation of interoperability between data providers. The formal representation of geospatial knowledge to advance geospatial interoperability is a growing research area. Tools and methods such as those outlined in this paper have the potential to support these efforts.

Community participation and inclusion: People with disabilities defining their place

Disability-related public policy currently emphasises reducing the number of people experiencing exclusion from the spaces of the social and economic majority as being the pre-eminent indicator of inclusion. Twenty-eight adult, New Zealand vocational service users collaborated in a participatory action research project to develop shared understandings of community participation. Analysis of their narratives suggests that spatial indices of inclusion are quiet in potentially oppressive ways about the ways mainstream settings can be experienced by people with disabilities and quiet too about the alternative, less well sanctioned communities to which people with disabilities have always belonged. Participants identified five key attributes of place as important qualitative antecedents to a sense of community belonging. The potential of these attributes and other self-authored approaches to inclusion are explored as ways that people with disabilities can support the policy objective of effecting a transformation from disabling to inclusive communities.

Gov 2.0: Towards a User Generated State?

New elements associated withWeb 2.0 relating to interactivity and end-user focus have combined with the availability of newlevels of information to encourage the development of what may be termed a Gov 2.0 approach.This, in combination with recent initiatives in the modernising government programme, has emphasised new levels of public participation and engagement with government as well as a re-engineering of public services tomake them more responsive to their end users. Adopting a governmentality perspective, it is argued that this involves a wider process of governing through constructing and reconstructing ideas of the public, community and individual citizen-consumers who take on a role in their own governance. It is argued that this fundamental re-working of the nature of what is public represents a constitutional change that is perhaps more signi¢cant than the constitutional reform programme directed to formal government which attracts more attention

Novel Radio Link Buffer Management Schemes for End-User Multi-class Traffic in High Speed Packet Access Networks

The requirement to provide multimedia services with QoS support in mobile networks has led to standardization and deployment of high speed data access technologies such as the High Speed Downlink Packet Access (HSDPA) system. HSDPA improves downlink packet data and multimedia services support in WCDMA-based cellular networks. As is the trend in emerging wireless access technologies, HSDPA supports end-user multi-class sessions comprising parallel flows with diverse Quality of Service (QoS) requirements, such as real-time (RT) voice or video streaming concurrent with non real-time (NRT) data service being transmitted to the same user, with differentiated queuing at the radio link interface. Hence, in this paper we present and evaluate novel radio link buffer management schemes for QoS control of multimedia traffic comprising concurrent RT and NRT flows in the same HSDPA end-user session. The new buffer management schemes—Enhanced Time Space Priority (E-TSP) and Dynamic Time Space Priority (D-TSP)—are designed to improve radio link and network resource utilization as well as optimize end-to-end QoS performance of both RT and NRT flows in the end-user session. Both schemes are based on a Time-Space Priority (TSP) queuing system, which provides joint delay and loss differentiation between the flows by queuing (partially) loss tolerant RT flow packets for higher transmission priority but with restricted access to the buffer space, whilst allowing unlimited access to the buffer space for delay-tolerant NRT flow but with queuing for lower transmission priority. Experiments by means of extensive system-level HSDPA simulations demonstrates that with the proposed TSP-based radio link buffer management schemes, significant end-to-end QoS performance gains accrue to end-user traffic with simultaneous RT and NRT flows, in addition to improved resource utilization in the radio access network.

Mature students – participation in maths support and progression

Maths support at the Learning Development Service takes the form of drop-in contact, one-to-one appointments and workshops. Analysis over three years from 2010/11 to 2012/13 shows that 45% of one-to-one appointments involved a mature student, defined at Queen’s University Belfast (QUB) as one who has had a break in full-time study (normally a minimum of two years). This is a very high proportion given that 4% of students at QUB are mature. Considering engineering undergraduates only, the fraction of one-to-one appointments involving mature students was also 45%. This study can report a wide variation in terms of progression of mature students in engineering and aims to consider how more traditional undergraduate learners could be persuaded to adopt the attitudes of mature students in partaking of maths support.

Technology, work organisation and job quality in the service sector: an introduction’

This special issue volume is concerned with how technology is changing the nature of work and working conditions while generating new products and new forms of service delivery. The five articles included in this volume cover service work, from the routine and clerical through to highly credentialed and professional work. Although some of the established challenges concerning the impact of Information and Communication Technology (ICT) on work and workplaces are evident in the articles, it is also clear that new service delivery processes demand new skills and training to some extent. Overall findings indicate that while ICT competencies are important, they need to be supplemented by the soft skills that are crucial for effective customer interactions and more open work systems with greater autonomy and participation whereby flexible work teams can have a positive impact on job quality outcomes. This introductory article examines technology and the changing nature of work through three strands of interpretation, prior to introducing the five articles in this special issue.

The rise of the digital citizen-stakeholder: rebalancing multistakeholder governance

The principle feature in the evolution of the internet has been its ever growing reach to include old and young, rich and poor. The internet’s ever encroaching presence has transported it from our desktop to our pocket and into our glasses. This is illustrated in the Internet Society Questionnaire on Multistakeholder Governance, which found the main factors affecting change in the Internet governance landscape were more users online from more countries and the influence of the internet over daily life. The omnipresence of the internet is self- perpetuating; its usefulness grows with every new user and every new piece of data uploaded. The advent of social media and the creation of a virtual presence for each of us, even when we are not physically present or ‘logged on’, means we are fast approaching the point where we are all connected, to everyone else, all the time. We have moved far beyond the point where governments can claim to represent our views which evolve constantly rather than being measured in electoral cycles.
The shift, which has seen citizens as creators of content rather than consumers of it, has undermined the centralist view of democracy and created an environment of wiki democracy or crowd sourced democracy. This is at the heart of what is generally known as Web 2.0, and widely considered to be a positive, democratising force. However, we argue, there are worrying elements here too. Government does not always deliver on the promise of the networked society as it involves citizens and others in the process of government. Also a number of key internet companies have emerged as powerful intermediaries harnessing the efforts of the many, and re- using and re-selling the products and data of content providers in the Web 2.0 environment. A discourse about openness and transparency has been offered as a democratising rationale but much of this masks an uneven relationship where the value of online activity flows not to the creators of content but to those who own the channels of communication and the metadata that they produce.
In this context the state is just one stakeholder in the mix of influencers and opinion formers impacting on our behaviours, and indeed our ideas of what is public. The question of what it means to create or own something, and how all these new relationships to be ordered and governed are subject to fundamental change. While government can often appear slow, unwieldy and even irrelevant in much of this context, there remains a need for some sort of political control to deal with the challenges that technology creates but cannot by itself control. In order for the internet to continue to evolve successfully both technically and socially it is critical that the multistakeholder nature of internet governance be understood and acknowledged, and perhaps to an extent, re- balanced. Stakeholders can no longer be classified in the broad headings of government, private sector and civil society, and their roles seen as some sort of benign and open co-production. Each user of the internet has a stake in its efficacy and each by their presence and participation is contributing to the experience, positive or negative of other users as well as to the commercial success or otherwise of various online service providers. However stakeholders have neither an equal role nor an equal share. The unequal relationship between the providers of content and those who simple package up and transmit that content - while harvesting the valuable data thus produced - needs to be addressed. Arguably this suggests a role for government that involves it moving beyond simply celebrating and facilitating the on- going technological revolution. This paper reviews the shifting landscape of stakeholders and their contribution to the efficacy of the internet. It will look to critically evaluate the primacy of the individual as the key stakeholder and their supposed developing empowerment within the ever growing sea of data. It also looks at the role of individuals in wider governance roles. Governments in a number of jurisdictions have sought to engage, consult or empower citizens through technology but in general these attempts have had little appeal. Citizens have been too busy engaging, consulting and empowering each other to pay much attention to what their governments are up to. George Orwell’s view of the future has not come to pass; in fact the internet has insured the opposite scenario has come to pass. There is no big brother but we are all looking over each other’s shoulder all the time, while at the same time a number of big corporations are capturing and selling all this collective endeavour back to us.

The design and implementation of a study to investigate the effectiveness of community vs hospital eye service follow-up for patients with neovascular age-related macular degeneration with quiescent disease

Introduction
Standard treatment for neovascular age-related macular degeneration (nAMD) is intravitreal injections of anti-VEGF drugs. Following multiple injections, nAMD lesions often become quiescent but there is a high risk of reactivation, and regular review by hospital ophthalmologists is the norm. The present trial examines the feasibility of community optometrists making lesion reactivation decisions.

Methods
The Effectiveness of Community vs Hospital Eye Service (ECHoES) trial is a virtual trial; lesion reactivation decisions were made about vignettes that comprised clinical data, colour fundus photographs, and optical coherence tomograms displayed on a web-based platform. Participants were either hospital ophthalmologists or community optometrists. All participants were provided with webinar training on the disease, its management, and assessment of the retinal imaging outputs. In a balanced design, 96 participants each assessed 42 vignettes; a total of 288 vignettes were assessed seven times by each professional group.The primary outcome is a participant's judgement of lesion reactivation compared with a reference standard. Secondary outcomes are the frequency of sight threatening errors; judgements about specific lesion components; participant-rated confidence in their decisions about the primary outcome; cost effectiveness of follow-up by optometrists rather than ophthalmologists.

Discussion
This trial addresses an important question for the NHS, namely whether, with appropriate training, community optometrists can make retreatment decisions for patients with nAMD to the same standard as hospital ophthalmologists. The trial employed a novel approach as participation was entirely through a web-based application; the trial required very few resources compared with those that would have been needed for a conventional randomised controlled clinical trial.

Gestão de qualidade de serviço baseada em políticas

A evolução observada nas redes de comunicações durante a última década traduziu-se na diversificação de serviços que utilizam a rede, no aumento das taxas de transferência e na massificação da utilização de serviços de acesso à Internet e de comunicações celulares. Durante esta década, várias organizações, das quais se destacam os operadores de telecomunicações, têm dedicado consideráveis esforços no sentido de definir e normalizar arquitecturas de redes de próxima geração. A principal característica deste tipo de rede reside no facto de possuir uma arquitectura modular capaz de fornecer serviços multimédia a clientes de uma rede de acesso com características tecnológicas heterogéneas. Os trabalhos de normalização das arquitecturas de rede NGN têm-se limitado, até ao momento, a especificar detalhes relativos ao funcionamento da rede não tendo ainda sido definida a arquitectura de gestão. Em termos de tecnologias de gestão de redes, foram propostos nas últimas duas décadas novos paradigmas de gestão, novos modelos de dados, novos protocolos de transporte e várias linguagens de definição de informação de gestão. Os modelos de dados têm vindo a ser enriquecidos, os protocolos são mais flexíveis e poderosos, as soluções de gestão oferecem interoperabilidade acrescida e as linguagens permitem definir formatos de configuração mais ricos. Simultaneamente tem crescido a complexidade das soluções de gestão, aumentado a sobrecarga causada pelo aumento de complexidade nos equipamentos bem como nas plataformas computacionais que suportam os sistemas de gestão. O presente trabalho propõe uma solução de gestão para redes NGN capaz de gerir os recursos de rede garantindo Qualidade de Serviço. A solução de gestão proposta inclui uma plataforma de execução de políticas que utiliza os eventos ocorridos na rede para empreender acções de configuração, autonomizando o processo de gestão. Inclui uma avaliação da complexidade de várias tecnologias de gestão estudando a sobrecarga causada pela tecnologia tanto no processo de gestão como na operação da rede. É ainda estudada a escalabilidade das várias tecnologias e analisado o seu comportamento num cenário da rede de um operador de telecomunicações. O trabalho propõe ainda uma metodologia de configuração integrada dos elementos de gestão, através de uma interface de configuração amigável para o administrador do sistema.

Tecnologias de informação e comunicação e o cidadão sénior : estudo sobre o impacto em variáveis psicossociais e a conceptualização de serviços com e para o cidadão sénior

Perante uma sociedade em célere envelhecimento demográfico e permanente avanço tecnológico, justifica-se a aposta em estudos que potenciem a ação comunicativa e a diminuição do isolamento social decorrente das perdas biopsicossociais associadas à idade sénior. Esta tese possui quatro objetivos de estudo: i) pretende-se investigar qual é o impacto da utilização das Tecnologias de Informação e Comunicação (TIC) no autoconceito (AC), no ânimo e na qualidade de vida (QV) de um grupo de seniores; ii) perceber se existe e qual a relação entre as variáveis independentes sexo, idade, estado civil, escolaridade, profissão, IPSS, regime de frequência, tempo na IPSS, orientação para frequentar a IPSS, visita de familiares e visita de amigos e as variáveis dependentes AC, ânimo, QV e respetivos fatores e domínios, nos momentos de pré e pós-teste; iii) perceber se a sua participação no processo de conceptualização de um serviço de comunicação assíncrona, email, influencia a sua usabilidade ao nível das componentes eficácia, eficiência e satisfação; iv) e sugerir a componente política da comunidade online sénior em desenvolvimento no âmbito do Projeto SEDUCE. Para o desenvolvimento do estudo estabeleceram-se parcerias com quatro Instituições Particulares de Segurança Social do concelho de Aveiro, integradas no âmbito do projeto SEDUCE. Os instrumentos utilizados para a avaliação do autoconceito, do ânimo e da qualidade de vida foram o Inventário Clínico de Auto-Conceito, a Escala de Ânimo do Centro Geriátrico de Philadelphia e a Escala de Qualidade de Vida da Organização Mundial de Saúde WHOQOL-Bref, respetivamente. No processo de conceptualização do serviço de email e da componente política da comunidade online utilizou-se a observação participativa e o contextual design. O estudo envolveu a participação de 42 seniores distribuídos por duas condições experimentais: 22 seniores do grupo experimental utilizaram as TIC duas vezes por semana (em sessões de 90 minutos cada, num total de 80 sessões) e 19 seniores do grupo de controlo passivo não experimentaram qualquer intervenção. Para a avaliação das variáveis psicossociais realizaram-se dois momentos de avaliação, antes e depois de 11 meses de intervenção, de Agosto de 2011 a Julho de 2012. Ao longo das sessões de envolvimento com as TIC observou-se que os seniores apresentam, continuamente, dificuldades em: manipular o rato e percecionar a sua ação no monitor; fazer a distinção entre teclas (enter, spacebar, delete, caps lock entre outras); em utilizar duplas teclas para colocar pontuação e acentuação; iniciar atividades no Microsoft Office Word; selecionar a informação disponibilizada em motores de pesquisa; perceber quais as zonas clicáveis; falta de confiança em efetivar ações; receio em iniciar nova atividades, pela falta de conhecimento e pelo medo de errar; memorizar endereços de email e passwords; e dar continuidade às tarefas. Na utilização do serviço de email consideram importante receber resposta quando enviam uma mensagem, assim como responder sempre aos remetentes; raramente colocam assunto nas mensagens; e expressam grande satisfação ao receber mensagens de familiares e/ou amigos. O processo de desenvolvimento de serviços com a participação ativa dos seniores revela-se exequível mas é necessário adaptar as práticas: os processos devem ser iterativos; evitar linguagem formal; clarificar o objetivo; deixar os seniores pensar em voz alta; dar-lhes tempo; mantê-los focados e não conduzi-los nas tarefas. Os resultados sugerem que houve aumento significativo do domínio físico da qualidade de vida do grupo experimental. Os participantes que exprimiram maiores níveis de satisfação ao utilizar as TIC apresentam uma perspetiva mais positiva sobre a maturidade psicológica e menos solidão e insatisfação. No grupo experimental e no grupo de controlo passivo verificam-se relações entre as variáveis independentes e as variáveis dependentes, quer no momento de pré-teste como de pós-teste. Conclui-se que a participação dos seniores no processo de conceptualização do serviço de email permitiu fomentar a componente eficácia da usabilidade mas não a satisfação ao utilizar o mesmo. Os resultados sobre a eficiência são inconclusivos. Sobre a componente política os seniores validam a existência de termos de utilização que orientem o comportamento de todos os utilizadores, assim como de uma política de privacidade. A área de registo proposta é adequada ao utilizador sénior.

A Methodological Approach to User Evaluation and Assessment of a Virtual Environment Hangout

Innovation in virtual reality and motion sensing devices is pushing the development of virtual communication platforms towards completely immersive scenarios, which require full user interaction and create complex sensory experiences. This evolution influences user experiences and creates new paradigms for interaction, leading to an increased importance of user evaluation and assessment on new systems interfaces and usability, to validate platform design and development from the users’ point of view. The REVERIE research project aims to develop a virtual environment service for realistic inter-personal interaction. This paper describes the design challenges faced during the development process of user interfaces and the adopted methodological approach to user evaluation and assessment.

Development and implementation of a new service delivery model for children with disabilities : implications for DCD

There is a general consensus that new service delivery models are needed for children with developmental coordination disorder (DCD). Emerging principles to guide service delivery include the use of graduated levels of intensity and evidence-based services that focus on function and participation. Interdisciplinary, community-based service delivery models based on best practice principles are needed. In this case report, we propose the Apollo model as an example of an innovative service delivery model for children with DCD. We describe the context that led to the creation of a program for children with DCD, describe the service delivery model and services, and share lessons learned through implementation. The Apollo model has 5 components: first contact, service delivery coordination, community-, group- and individual-interventions. This model guided the development of a streamlined set of services offered to children with DCD, including early-intake to share educational information with families, community interventions, inter-disciplinary and occupational therapy groups and individual interventions. Following implementation of the Apollo model, waiting times decreased and numbers of children receiving services increased, without compromising service quality. Lessons learned are shared to facilitate development of other practice models to support children with DCD.

Children's television: the soft underbelly of public service broadcasting

The provision of children's content should be a key constituent of the public service brand, but has often been viewed as a programme category at risk. Certainly in many countries children's television has moved from the 'scarcity' associated with terrestrial provision, to the 'plenty' of digital (see Ellis 2000). However in spite of a range of dedicated public service children's channels in Europe (CBeebies, Kika, Z@ppelin), domestically produced children's television in Europe is notoriously under-resourced if not marginalised. There is a pronounced reliance on imports (particularly on commercial television) notwithstanding the launch by US-owned multinationals (Disney, Nickelodeon, Cartoon Network) of localised versions of their children's television channels in many European countries. Within the broader context of global developments in children's media, this paper starts by outlining the recent and rapid crisis in British children's television and the factors that caused it. This was a crisis, which caught broadcasters and producers by surprise in the middle of 2006, but reflects many of the challenges faced by the children's television sector in other countries. It clearly demonstrated how a combination of the lack of regulatory protection, a change in commercial priorities among broadcasters, advertising restrictions, budgetary pressures and the competitive environment at home and abroad all combined to reinforce the trend towards a contraction of domestic production. The crisis also served to underline the dominance of the BBC - both as a representative of public service principles, and as the dominant producer and commissioner in the market. With the reasons underpinning the crisis explained, the paper will then analyse how the children's television community responded to the crisis and with what effect. Based on interviews, contemporary accounts and documentary evidence the paper will chart the converging and diverging views of broadcasters, producers, regulatory authority Ofcom, and a range of advocacy groups which represent children's interests and the industry. What arguments were elaborated in favour of protecting children's television as an integral part of the public service media brand? Can lessons be learned about how best to ensure the origination of children's media within a public service environment? Can developments in the UK be used to provide insight into how children's media might develop further?

Business Models for Cloud Computing: Experiences from Developing Modeling & Simulation as a Service Applications in Industry

The potential of cloud computing is gaining significant interest in Modeling & Simulation (M&S). The underlying concept of using computing power as a utility is very attractive to users that can access state-of-the-art hardware and software without capital investment. Moreover, the cloud computing characteristics of rapid elasticity and the ability to scale up or down according to workload make it very attractive to numerous applications including M&S. Research and development work typically focuses on the implementation of cloud-based systems supporting M&S as a Service (MSaaS). Such systems are typically composed of a supply chain of technology services. How is the payment collected from the end-user and distributed to the stakeholders in the supply chain? We discuss the business aspects of developing a cloud platform for various M&S applications. Business models from the perspectives of the stakeholders involved in providing and using MSaaS and cloud computing are investigated and presented.
