Developing front-end Web 2.0 technologies to access services, content and things in the future Internet

The future Internet is expected to be composed of a mesh of interoperable web services accessible from all over the web. This approach has not yet caught on since global user?service interaction is still an open issue. This paper states one vision with regard to next-generation front-end Web 2.0 technology that will enable integrated access to services, contents and things in the future Internet. In this paper, we illustrate how front-ends that wrap traditional services and resources can be tailored to the needs of end users, converting end users into prosumers (creators and consumers of service-based applications). To do this, we propose an architecture that end users without programming skills can use to create front-ends, consult catalogues of resources tailored to their needs, easily integrate and coordinate front-ends and create composite applications to orchestrate services in their back-end. The paper includes a case study illustrating that current user-centred web development tools are at a very early stage of evolution. We provide statistical data on how the proposed architecture improves these tools. This paper is based on research conducted by the Service Front End (SFE) Open Alliance initiative.

Sustainability of Open Access Services: Phase 4 Workshop report

Phase 4: Review of the conditions under which individual services and platforms can be sustained On Tuesday 1 October 2013, in Bristol, United Kingdom, Knowledge Exchange brought together a group of international Open Access Service providers to discuss the sustainability of their services. A number of recurring lessons learned were mentioned; Though project funding can be used to start up a service, it does not guarantee the continuation of a service and it can be hard to establish the service as a viable entity, standing on its own feet. Research funders should be aware that if they have policies or mandates for making research outputs available they will eventually also be responsible for on-going support for the underlying infrastructure. At present some services are used globally but the costs are only covered by a limited geographic spread, sometimes only a number of institutions or only one country. Finding other funding sources can be challenging. Various routes were mentioned including commercial partnerships, memberships, offering additional paid services or using a Freemium model. There is not one model that will fit all. As more services turn to library sponsorship to sustain them, one strategy might be to bundle the requests and approach a group of research and infrastructure funders or institutions (and others) with a package rather than each service going through the same resource consuming process of soliciting funding. This will also allow the community to identify gaps, dependencies and overlap in the services. The possibility of setting up an organisation to bundle the services was discussed and a number of risks were identified.

Universal Set-top Box: A Simple Design to Provide Accessible Services

This paper presents the design of a low cost accessible digital television set-top box. This set-top box was designed and tested to the International ISDB-T system and considered the adoption of solutions that would provide accessible services in digital television in the simplest digital television receiver. The accessible set-top box was evaluated regarding the processing and memory requirements impacts to provide the features for accessible services. The work presents also the access services bandwidth consumption analysis(1).

Le recours aux services de santé buccodentaire au sein de localités autochtones du Nord du Québec

Le mode de vie des Cris de la Baie James a changé radicalement au cours des dernières années. La carie dentaire est maintenant un problème de santé publique important, et des données montrent que les Cris utilisent les services dentaires en situation d’urgence plutôt qu’en prévention. Il apparaît donc important de savoir si les Cris sont satisfaits des services dentaires publics qui sont disponibles et de mieux comprendre leurs besoins. Ce projet aborde les deux questions suivantes : Quelles sont les attentes des résidants des localités cries pour les services dentaires? Est-ce que les services existants répondent aux attentes des gens? Nous avons mené une recherche qualitative descriptive basée sur des entrevues semi- structurées (n = 13). Les entrevues ont été enregistrées et transcrites. Nous avons ensuite procédé à une analyse inductive-déductive des transcriptions. Les résultats montrent que les participants ont des attentes très variées, mais que celles-ci sont rarement satisfaites. Premièrement, ils veulent accéder rapidement aux services lorsqu’ils en ressentent le besoin, par exemple en présence de douleur dentaire. Les participants désirent aussi transiger avec des professionnels dentaires attentionnés et expérimentés, ce qui n’est pas toujours le cas, selon eux. En conclusion, nous aimerions faire trois principales recommandations : améliorer l’accès aux services dentaires, en particulier en situation d’urgence; entraîner les professionnels dentaires en approches centrées sur le patient et pour en savoir plus sur la culture crie; et dialoguer avec les Cris pour développer, mettre en place et évaluer les services de santé dentaire.

Using small area estimation and geographic information systems technology to target health services for the uninsured

The three articles that comprise this dissertation describe how small area estimation and geographic information systems (GIS) technologies can be integrated to provide useful information about the number of uninsured and where they are located. Comprehensive data about the numbers and characteristics of the uninsured are typically only available from surveys. Utilization and administrative data are poor proxies from which to develop this information. Those who cannot access services are unlikely to be fully captured, either by health care provider utilization data or by state and local administrative data. In the absence of direct measures, a well-developed estimation of the local uninsured count or rate can prove valuable when assessing the unmet health service needs of this population. However, the fact that these are “estimates” increases the chances that results will be rejected or, at best, treated with suspicion. The visual impact and spatial analysis capabilities afforded by geographic information systems (GIS) technology can strengthen the likelihood of acceptance of area estimates by those most likely to benefit from the information, including health planners and policy makers. ^ The first article describes how uninsured estimates are currently being performed in the Houston metropolitan region. It details the synthetic model used to calculate numbers and percentages of uninsured, and how the resulting estimates are integrated into a GIS. The second article compares the estimation method of the first article with one currently used by the Texas State Data Center to estimate numbers of uninsured for all Texas counties. Estimates are developed for census tracts in Harris County, using both models with the same data sets. The results are statistically compared. The third article describes a new, revised synthetic method that is being tested to provide uninsured estimates at sub-county levels for eight counties in the Houston metropolitan area. It is being designed to replicate the same categorical results provided by a current U.S. Census Bureau estimation method. The estimates calculated by this revised model are compared to the most recent U.S. Census Bureau estimates, using the same areas and population categories. ^

Getting the run around: accessing services for children with developmental co-ordination disorder

Background Accessing services for children with developmental co-ordination disorder (DCD) is frequently difficult for parents who have to navigate both health and education systems to find a diagnosis and appropriate interventions. Method A qualitative study design incorporating a phenomenological perspective was utilized to understand the nature of the experiences of these parents in attempting to access support for their children with DCD. Twelve parents, whose children attended the Kids Skills Clinic at the University of Western Ontario and were identified as having DCD, were interviewed by the second author. Interviews were transcribed verbatim and analysed using constant comparative method. Member checking, peer checking and code-recoding were carried out to enhance rigour in data analysis. Results A number of themes emerged focusing on the common problems experienced leading to occupational therapy referral. Parents' journeys to seek and access services for their children with DCD were characterized by a sense of maternal knowing, experience of frustration, trivialization of the problem, a sense of 'going it alone', and 'getting the run around'. Conclusions Implications for health and educational professionals working with children, in terms of recognition of DCD and referral for services, are described.

On the way to universal coverage of maternal services in Iringa rural District in Tanzania. Who is yet to be reached?

Background: Strategies to tackle maternal mortality in sub-Saharan Africa include expanding coverage of reproductive services.Even where high, more vulnerable women may not access services. No data is available on high coverage determinants. We investigated this in Tanzania in a predicted high utilization area. Methods: Data was collected through a household survey of 464 women with a recent delivery. Primary outcomes were facility delivery and ≥4 ANC visits. Determinants were analysed using multivariate regression. Results: Almost all women had attended ANC, though only 58.3% had ≥4 visits. ≥4 visits were more likely in the youngest age group (OR 2.7 95% CI 1.32–5.49, p=0.008), and in early ANC attenders (OR 3.2 95% CI 2.04–4.90, p<0.001). Facility delivery was greater than expected (87.7%), more likely in more educated women (OR 2.7 95% CI 1.50–4.75, p=0.002), in those within 5 kilometers of a facility (OR 3.2 95% CI 1.59–6.48, p=0.002), and for early ANC attenders (OR 2.4 95% CI 1.20–4.91, p=0.02). Conclusion: Rural contexts can achieve high facility delivery coverage. Based on our findings, strategies to reach women yet unserved should include promotion of early ANC start particularly for the less educated, and improvement of distant communities' access to facilities.

Determinants of general practitioner use among women in Australia

This study investigates the use of general practitioner services by women in Australia. Although there is a universal health insurance system (Medicare) in Australia, there are variations in access to services and out of pocket costs for services. Survey data from 2350 mid-age (45-50 years) and 2102 older (70-75 years) women participating in the Australian Longitudinal Study on Women's Health were linked with Medicare data to provide a range of individual and contextual variables hypothesised to explain general practitioner use. Structural equation modelling showed that physical health was the most powerful explanatory factor of general practitioner use. However, after adjusting for self-reported health, out of pocket cost per consultation was inversely associated with use of services. The out of pocket cost was generally lower for women with low socioeconomic status but cost was also directly related to geographical remoteness. Women living in more remote areas had higher out of pocket costs and poorer access to services. Women who reported better access to care were more likely to be satisfied with their most recent general practice consultation and less likely to be sceptical of the value of medical care. These results show the need for health policies that improve the equitable use of general practitioner services in Australia. (C) 2001 Elsevier Science Ltd. All rights reserved.

Rapid prototyping of ubiquitous computing environments

Ubiquitous computing raises new usability challenges that cut across design and development. We are particularly interested in environments enhanced with sensors, public displays and personal devices. How can prototypes be used to explore the users' mobility and interaction, both explicitly and implicitly, to access services within these environments? Because of the potential cost of development and design failure, these systems must be explored using early assessment techniques and versions of the systems that could disrupt if deployed in the target environment. These techniques are required to evaluate alternative solutions before making the decision to deploy the system on location. This is crucial for a successful development, that anticipates potential user problems, and reduces the cost of redesign. This thesis reports on the development of a framework for the rapid prototyping and analysis of ubiquitous computing environments that facilitates the evaluation of design alternatives. It describes APEX, a framework that brings together an existing 3D Application Server with a modelling tool. APEX-based prototypes enable users to navigate a virtual world simulation of the envisaged ubiquitous environment. By this means users can experience many of the features of the proposed design. Prototypes and their simulations are generated in the framework to help the developer understand how the user might experience the system. These are supported through three different layers: a simulation layer (using a 3D Application Server); a modelling layer (using a modelling tool) and a physical layer (using external devices and real users). APEX allows the developer to move between these layers to evaluate different features. It supports exploration of user experience through observation of how users might behave with the system as well as enabling exhaustive analysis based on models. The models support checking of properties based on patterns. These patterns are based on ones that have been used successfully in interactive system analysis in other contexts. They help the analyst to generate and verify relevant properties. Where these properties fail then scenarios suggested by the failure provide an important aid to redesign.

Desenvolvimento, implementação e testes de um sistema de comunicação sem fio heterogêneo para acesso à serviços: aplicações na telemedicina e domótica

Nos últimos de 20 anos, economia e tecnologia evoluíram em muitas direções e em novas áreas. Muitas dessas evoluções criaram oportunidades que estão sendo consideradas na concepção de futuras redes de comunicação. Estas novas possibilidades estão relacionadas à, sobretudo, utilização da internet para o acesso à serviços e englobam: mobilidade; tecnologias de baixo custo; crescimento e empregos (pela Internet participa-se de cada processo de negócios e produção); serviços; educação (oportunidade para as pessoas crescerem e se desenvolverem); entretenimento (mundos virtuais para o lazer, compras e jogos); volume de tráfego maior (texto, voz, imagens, vídeo). Como uma consequência, a Internet se tornou, semelhante a eletricidade ou água, um bem público. Com quase 2 bilhões de usuários (aproximadamente 28% da população mundial), a Internet está se tornando, cada vez mais, uma infraestrutura difusivo oferecendo em qualquer lugar, a qualquer momento conectividade e serviços. Este mundo da Internet atual é o resultado de sucessivas alterações que aconteceram desde o seu surgimento e que tornaram a infraestrutura de comunicação de importância crítica. Em termos de tecnologias de comunicação, os sistemas móveis sem fio têm um lugar especial devido a sua difusão excepcional na última década e que, junto com a Internet, tem permitido o aparecimento de dispositivos inteligentes, a introdução de novos serviços inovadores e exigindo, para tanto, um ambiente que suporte a inovação e criatividade. Porém, os vários padrões de redes para suporte, principalmente, ao acesso de última milha são desvantagens na perspectiva do usuário, pois este tem de se habilitar nessas redes (contratar os serviços) e, não raro, ter terminais específicos para o acesso. A idéia de um padrão único para estas redes não obteve resultados satisfatórios e uma solução aponta para a integração dessas redes para prover acesso único e transparente ao usuário. Esse trabalho, portanto, apresenta uma solução embarcada para integrar padrões de comunicações sem fio heterogênea do tipo IEEE 802.15.4 ZigBee, IEEE 802.20 GSM/GPRS e IEEE 802.2 Wi-Fi. Essa heterogeneidade de tecnologias sem fio permite a um usuário em movimento, através de seu terminal local ou remoto, acessar aplicativos e serviços de forma transparente. A avaliação de desempenho da solução foi realizada utilizando-se dois tipos de serviços: domótica e telemedicina. Os resultados indicaram que a solução proposta consegue integrar e prover os serviços com segurança e confiabilidade.
