New Generation Sensor Web Enablement

Many sensor networks have been deployed to monitor Earth’s environment, and more will follow in the future. Environmental sensors have improved continuously by becoming smaller, cheaper, and more intelligent. Due to the large number of sensor manufacturers and differing accompanying protocols, integrating diverse sensors into observation systems is not straightforward. A coherent infrastructure is needed to treat sensors in an interoperable, platform-independent and uniform way. The concept of the Sensor Web reflects such a kind of infrastructure for sharing, finding, and accessing sensors and their data across different applications. It hides the heterogeneous sensor hardware and communication protocols from the applications built on top of it. The Sensor Web Enablement initiative of the Open Geospatial Consortium standardizes web service interfaces and data encodings which can be used as building blocks for a Sensor Web. This article illustrates and analyzes the recent developments of the new generation of the Sensor Web Enablement specification framework. Further, we relate the Sensor Web to other emerging concepts such as the Web of Things and point out challenges and resulting future work topics for research on Sensor Web Enablement

Service users' experiences of a brief intervention service for children and adolescents : a service evaluation

Ten per cent of young people experience mental health difficulties at any one time. Prevention and early intervention leads to better prognosis for young people's mental well-being in the short and long term. Child and Adolescent Mental Health Services (CAMHS) must be able to provide swift and effective interventions for a range of difficulties to meet this need. This paper presents a service evaluation of the Brief Intervention Service in North Lincolnshire CAMHS. Nine young people and/or their families took part in semi-structured interviews that aimed to explore their experiences of receiving an intervention from the service. Template analysis was carried out to draw out themes from the interview transcripts. The three a priori themes were treatment outcomes, areas for potential improvement, and things that are working well; and an additional two emergent themes were emotional experience and managing practical barriers. In addition, all participants were asked about their satisfaction with the service and whether they would recommend the service to others. One hundred per cent reported feeling respected by their clinician when asked directly, and all felt that the service would be helpful for other young people and families. Overall, families were satisfied with the service and reported outcomes including improvements in symptomatology and family functioning. Specific recommendations as to how the service could be improved were made, which related to difficulties accessing the service, the content of the sessions, and communication within the service and with other services

Sir Humphrey and the professors: what does Whitehall want from academics?

According to this UK survey, the majority of senior civil servants actively engage positively with academic outputs. However, it is also clear that a significant minority does not engage at all with academics and that many do so in fairly limited ways. Overview What do (civil service) policymakers want from academics? A seemingly simple question, and one to which you would already think we had a pretty good answer. Academia represents a very rich source of ideas, facts and theories about how public policies of all sorts might work (or not). Somewhere around 25,000 to 50,000 UK academics work on specifically policy-relevant areas – this represents a massive pool of knowledge that could help policymakers. Despite this obvious situation, actually very little is known precisely about how academia and policymakers interact. There are some research projects that have explored the issue, but these have mostly been case studies from which it is hard to generalise. We decided to ask the whole of the British Senior Civil Service (SCS) how they relate to academic research and expertise. We invited all 4,000+ members of the SCS to fill in our online survey. About 8% responded, with a representative gender balance and spread across nearly all policy areas, which is a reasonably good sample. Moreover the variations in responses suggest there was no obvious self-selection bias – it certainly wasn’t only those positive about academic outputs that responded. We asked a series of questions about how they access and use academic research and expertise and what impact this has on policymaking. Some of their answers were expected, and some were surprises that challenged standard assumptions. Overall, the impression from our survey is that the majority of senior civil servants actively engage positively with academic outputs. However, it is also clear that a significant minority does not engage at all with academics and that many do so in fairly limited ways. Unsurprisingly perhaps, senior civil servants had a predilection for “pre-digested” results of research and academic expertise. Their preference for “first contact” was briefings or reports (79%), or media reports of academic outputs in newspapers and weeklies (61%) or professional journals (55%)

Exploring people’s candidacy for mobile health–supported HIV testing and care services in rural Kwazulu-Natal, South Africa: qualitative study

BACKGROUND: The use of mobile communication technologies (mHealth: mobile health) in chronic disease management has grown significantly over the years. mHealth interventions have the potential to decentralize access to health care and make it convenient, particularly in resource-constrained settings. It is against this backdrop that we aimed to codevelop (with potential users) a new generation of mobile phone-connected HIV diagnostic tests and Web-based clinical care pathways needed for optimal delivery of decentralized HIV testing, prevention, and care in low- and middle-income countries. OBJECTIVE: The aim of this study was to understand ways in which an mHealth intervention could be developed to overcome barriers to existing HIV testing and care services and promote HIV self-testing and linkage to prevention and care in a poor, HIV hyperendemic community in rural KwaZulu-Natal, South Africa. METHODS: A total of 54 in-depth interviews and 9 focus group discussions were conducted with potential users (including health care providers) in 2 different communities. Theoretically informed by the candidacy framework, themes were identified from the interview transcripts, manually coded, and thematically analyzed. RESULTS: Participants reported barriers, such as fear of HIV identity, stigma, long waiting hours, clinic space, and health care workers' attitudes, as major impediments to effective uptake of HIV testing and care services. People continued to reassess their candidacy for HIV testing and care services on the basis of their experiences and how they or others were treated within the health systems. Despite the few concerns raised about new technology, mobile phone-linked HIV testing was broadly acceptable to potential users (particularly men and young people) and providers because of its privacy (individual control of HIV testing over health provider-initiated testing), convenience (individual time and place of choice for HIV testing versus clinic-based testing), and time saving. CONCLUSIONS: Mobile phone-connected HIV testing and Web-based clinical care and prevention pathways have the potential to support access to HIV prevention and care, particularly for young people and men. Although mHealth provides a way for individuals to test their candidacy for HIV services, the barriers that can make the service unattractive at the clinic level will also need to be addressed if potential demand is to turn into actual demand

Middleware Technologies for Cloud of Things - a survey

The next wave of communication and applications rely on the new services provided by Internet of Things which is becoming an important aspect in human and machines future. The IoT services are a key solution for providing smart environments in homes, buildings and cities. In the era of a massive number of connected things and objects with a high grow rate, several challenges have been raised such as management, aggregation and storage for big produced data. In order to tackle some of these issues, cloud computing emerged to IoT as Cloud of Things (CoT) which provides virtually unlimited cloud services to enhance the large scale IoT platforms. There are several factors to be considered in design and implementation of a CoT platform. One of the most important and challenging problems is the heterogeneity of different objects. This problem can be addressed by deploying suitable "Middleware". Middleware sits between things and applications that make a reliable platform for communication among things with different interfaces, operating systems, and architectures. The main aim of this paper is to study the middleware technologies for CoT. Toward this end, we first present the main features and characteristics of middlewares. Next we study different architecture styles and service domains. Then we presents several middlewares that are suitable for CoT based platforms and lastly a list of current challenges and issues in design of CoT based middlewares is discussed.Comment: http://www.sciencedirect.com/science/article/pii/S2352864817301268, Digital Communications and Networks, Elsevier (2017
