The cost of virtue : reward as well as feedback are required to reduce user ICT power consumption

This work was partly supported by the IU-AC project, funded by grant EP/J016756/1 from the Engineering and Physical Sciences Research Council (EPSRC).We show that students in a school lab environment will change their behaviour to be more energy efficient, when appropriate incentives are in place, and when measurement-based, real-time feedback about their energy usage is provided. Rewards incentivise `non-green' users to be `green' as well as encouraging those users who already claim to be `green'. Measurement-based feedback improves user energy awareness and helps users to explore and adjust their use of computers to become `greener', but is not sufficient by itself. In our measurements, weekly mean group energy use as a whole reduced by up to 16%; and weekly individual user energy consumption reduced by up to 56% during active use. The findings are drawn from our longitudinal study that involved 83 Computer Science students; lasted 48 weeks across 2 academic years; monitored a total of 26778 hours of active computer use; collected approximately 2TB of raw data.Publisher PD

Studying biological science does not lead to adoption of a healthy lifestyle

Aims: The lifestyle and physical activity (PA) habits of young people play a key role in the prevention of cardiovascular and metabolic diseases at older ages. The current generation of biological science students at university holds promise for better future medicine and medical technology. However, their physical fitness and lifestyle are often ignored. Methods: Lifestyle, PAs and common risk factors for cardiovascular disease before, and at, university were collected from 408 students using self-completed, anonymous surveys between the academic years of 2017 and 2019 from the School of Biological Sciences, University of Reading. Statistical analysis was performed using SAS® 9.4 software. Results: Among the 408 participants, 134 were male and 274 were female with a mean (SD) age of 19.6 (2.24). Approximately 19% of participants consumed alcohol beyond the safe limit of <14 units/week (112 g/week). Among them, 65% were males. Before university, 47% of students failed to meet the UK National Physical Activity Guidelines (NPAG) which increased to 56% during university with males exhibiting a steeper incline. Compared to their lifestyles before university, more students had insufficient sleep and displayed greater sedentariness during university. Moreover, 16% of students declared no engagement in PA which was greater than the value of 12% before university. Fitness perceptions worsened by 11% during university particularly for females. Statistical analysis revealed that gender, BMI and fitness perceptions were significantly correlated with PA levels. The most prevalent explanation for inadequacy in meeting NPAG was insufficient time. Conclusion: Compared to their pre-university lifestyles, biological science students at university are more likely to adopt unhealthier behaviours with less time for exercise and prolonged sedentary behaviours, which increases the risk for cardiovascular diseases. It is important to raise awareness of their fitness perceptions and to encourage health-promoting programmes at university

Client-side energy costs of video streaming

Through measurements on our testbed, we show how users of Netflix could make energy savings of up to 34% by adjusting video quality settings. We estimate the impacts of these quality settings on the energy consumption of client systems and the network. If users exercise choice in their video streaming habits, over 100 GWh of energy a year could be saved on a global scale. We discuss how providing energy usage information to users of digital video could enable them to make choices of video settings to reduce energy usage, and we estimate savings on associated electricity costs and carbon emissions.Postprin

mHealth through quantified-self : a user study

This work was partly supported by the IU-ATC project, funded by grant EP/J016756/1 from the Engineering and Physical Sciences Research Council (EPSRC). Chonlatee Khorakhun is funded by the Scottish Informatics and Computer Science Alliance (SICSA).We describe a user study of a mHealth prototype system based on a wellbeing scenario, exploiting the quantified-self approach to measurement and monitoring. We have used off-the-shelf equipment, with opensource, web-based, software, and exploiting the increasing popularity of smartphones and self-measurement devices in a user study. We emulate a mHealth scenario as a pre-clinical experiment, as a realistic alternative to a clinical scenario, with reduced risk to sensitive patient medical data. We discuss the efficacy of this approach for future mHealth systems for remote monitoring. Our system used the popular Fitbit device for monitoring personal wellbeing data, the Diaspora online social media platform (OSMP), and a simple Android/iOS remote notification application. We implemented remote monitoring, asynchronous user interaction, multiple actors, and user-controlled security and privacy mechanisms. We propose that the use of a quantified-self approach to mHealth is particularly valuable to undertake research and systems development.Postprin

Mobility as a first class function

Seamless host mobility has been a desirable feature for a long time, but was not part of the original design of the Internet architecture or protocols. Current approaches to network-layer mobility typically require additional network-layer entities for mobility management, which add complexity to the current engineering landscape of the Internet. We present a host-based, end-to-end architecture for host mobility using the Identifier-Locator Network Protocol (ILNP). ILNP provides mobility support as a first class function, since mobility management is controlled and managed by the end-systems, and does not require additional network-layer entities. We demonstrate an instance of ILNP that is a superset of IPv6 – called ILNPv6 – that is implemented by extending the current IPv6 code in the Linux kernel. We make a direct comparison of performance of ILNPv6 and Mobile IPv6, showing the improved performance of ILNPv6.Postprin

Nutrient Foramen of Fibula in relation to distal end, potential implications for vascularised bone graft surgery

Background Free vascularised fibular bone grafting has gained popularity in various Orthopaedic and Oral & maxillofacial reconstructive surgeries. The objective of the present study was to identify the morphology and topography of nutrient foramina of fibula and to determine the foraminal index (FI) of the fibula using a more surgeon friendly bony landmark. Methods The study comprised examination of 100 fibulae specimens. Each bone was divided into 03 parts and topographical analysis was performed on each section. The nutrient foramina were identified macroscopically using size 24-gauge needle. Modified Hughes formula was used to calculate the foraminal index using distance of foramen (DF) from distal end which is easier to palpate in living human beings, total length of fibula (TL); and the formula was DF/TL x100. Results With respect to fibulae, 98% had single foramen and foramen was absent in 2%. The mean foraminal index (FI) was 56% for fibulae using modified Hughes’ formula. The majority of the fibulae showed nutrient foramen in the middle 3rd in relation to distal end of fibula. Conclusion The study provides information on the morphology of nutrient foramina in relation to easily palpable landmark on living human beings, which can provide guidance to surgeon while performing microvascular bone transfer procedures

Evaluating the effectiveness of digital communication within the National Medication Safety Network for England

Objectives: The medication safety officer (MSO) role was created following a patient safety alert, with an action for MSOs to be active participants in a national network in England, which included regular online webinar meetings and an online forum. The aim of the study was to assess the effectiveness of digital platforms in facilitating interaction and communication by the MSO network. The objectives were to establish the proportion of MSOs who interact through monthly webinars and the online forum. A secondary objective was to identify barriers and facilitators for engaging digitally within the MSO network. Methods: An online survey was used alongside semistructured interviews. The online survey was disseminated to all 400 MSOs registered with the UK Department of Health Central Alerting System from December 2018 to February 2019. Interviewees were identified purposively through snowball sampling and voluntarily through the survey. Results: 84 MSOs responded to the survey (21% response rate) and 10 participated in the semistructured interviews. The majority of the respondents were pharmacists (79/84, 94%) from NHS large healthcare providers (44/84, 52%). MSO respondents (61/84, 73%) joined the monthly webinar and 47/84 (56%) believed the webinar was useful for networking. Ten (12%) did not attend the webinars due to technical difficulties or lack of time. The online forum was used less frequently, with a third (27/84, 32%) that had never used it. Conclusions: Digital communications through webinars and online forums were perceived by respondents as a way to facilitate networking but require a robust information technology infrastructure that can be accessed without difficulty. User-friendly platforms can help the MSO network achieve critical mass and greater interaction, allowing timely access to information

IP without IP addresses

D. Phoomikiattisak was funded by the Thai Government. B. Simpson was funded by Cisco Systems under a University Research Programme (URP) grant award.We discuss a key engineering challenge in implementing the Identifier- Locator Network Protocol (ILNP), as described in IRTF Experimental RFCs 6740-6748: enabling legacy applications that use the C sockets API. We have built the first two OS kernel implementations of ILNPv6 (ILNP as a superset of IPv6), in both the Linux OS kernel and the FreeBSD OS kernel. Our evaluation is in comparison with IPv6, in the context of a topical and challenging scenario: host mobility implemented as a purely end-to-end function. Our experiments show that ILNPv6 has excellent potential for deployment using existing IPv6 infrastructure, whilst offering the new properties and functionality of ILNP.Postprin

Traditional Conservation of Buffalo Breed by Pastoralists through Maintaining of Grassland Ecosystem, Banni-Kachchh, Gujarat-India

Banni region, situated at 23019’N to 23052’N to 68056’E to70032’E, comprises around 25,00 sq.km area under Bhuj taluka of Kutch district of Gujarat state, is home of Muslim nomadic pastoralists and Meghwal Hindus. Banni is situated in Arid climate, with high temperature in most of time which reached maximum up to 480C -500C during May June. Pastoral community, call themselves Maldhari, in Banni region depends on Banni Grassland for the raring of their livestock mainly Banni Buffalo which registered as 11th buffalo breed of India in 2011. Maldharis even rearing unique Kankarej Cattle for Milk Production and selling bullocks in Saurashtra region of Gujarat. Pastoral life style in Banni, promote pluralistic culture to stay united by respecting traditions of each community. Strong association with animals and nature, made them sensitive to grassland ecosystem therefore, they have been able to developed livestock rearing practices which are more ecologically sustainable. This paper attempts to understand the pastoral life of Maldharis as essential for breeding, marketing and sustainable use of resources particularly commons
