Maximizing Research Impact Through Institutional and National Open-Access Self-Archiving Mandates
No full textNo research institution can afford all the journals its researchers may need, so all articles are losing research impact (usage and citations). Articles made “Open Access,” (OA) by self-archiving them on the web are cited twice as much, but only 15% of articles are being spontaneously self-archived. The only institutions approaching 100% self-archiving are those that mandate it. Surveys show that 95% of authors will comply with a self-archiving mandate; the actual expe-rience of institutions with mandates has confirmed this. What institutions and funders need to mandate is that (1) immediately upon acceptance for publication, (2) the author’s final draft must be (3) deposited into the Institutional Repository. Only the depositing needs to be mandated; set-ting access privileges to the full-text as either OA or Restricted Access (RA) can be left up to the author. For articles published in the 93% of journals that have already endorsed self-archiving, access can be set as OA immediately; for the remaining 7%, authors can email the eprint in re-sponse to individual email requests automatically forwarded by the Repository
DaRe: Data Recovery Through Application Layer Coding for LoRaWAN
No full textLong-range wide-area network (LoRaWAN) is an energy-efficient and inexpensive networking technology that is rapidly being adopted for many Internet-of-Things applications. In this study, we perform extensive measurements on a new LoRaWAN deployment to characterise the spatio-temporal properties of the LoRaWAN channel. Our experiments reveal that LoRaWAN frames are mostly lost due to the channel effects, which are adverse when the end-devices are mobile. The frame losses are up to 70 percent, which can be bursty for both mobile and stationary scenarios. Frame losses result in data losses since the frames are transmitted only once in the basic configuration. To reduce data losses in LoRaWAN, we design a novel coding scheme for data recovery called DaRe that works on the application layer. DaRe combines techniques from convolutional and fountain codes. By implementing DaRe, we show that 99 percent of the data can be recovered with a code rate of 1/2 when the frame loss is up to 40 percent. Compared to the repetition coding scheme, DaRe provides 21 percent higher data recovery and can save up to 42 percent of the energy consumed on a transmission for 10-byte data units. We also show that DaRe provides better resilience to bursty frame losses.

Blood-Sugar Roulette: a case study of bio-geometric body-art
No full textBlood-Sugar Roulette (Eleanor Dare, 2012) is an augmented reality body art performance that unfolded within the confines of Sydenham Hill Wood, South London, in the late summer of 2012. The live performance script was defined and generated by software that dictated the movements and utterances of the protagonist, Krista, who was played by a software industry worker, Milica Janjić. The software developed by Eleanor Dare (referred to in this paper as “the author”) used biological data relating to her own blood-sugar levels and menstrual cycles to define core aspects of the performance. The core themes of the project are based on a true childhood event that occurred in the woods in 1976, when the author, aged eleven, was attacked and chased by an adult man. The author appears in this paper as an uncanny, not fully human, ‘depersonalized’ presence. The rationale for such an approach is embedded in this paper
Colocaciones con el verbo dare en Ovidio
No full textResumen: Este trabajo estudia el campo colocacional del verbo dare en las Metamorfosis de Ovidio. En latín, se emplean con frecuencia un tipo de construcciones en las que un verbo se presenta total o parcialmente deseman-tizado y el sustantivo que lo selecciona se comporta como predicado de la construcción; es el caso de ejemplos como: dare velas (zarpar), dare vulnera (herir), dare verba (decir), etc. Estas construcciones, conocidas como ‘cons-trucciones con verbo soporte’ (CVS), presentan variaciones distribucionales relacionadas con el autor y el género textual, y algunas CVS son exclusivas de un autor o un género concreto.
En este sentido, el estudio analiza, en la obra de Ovidio, las CVS formadas con el verbo dare, los diferentes sustantivos que lo seleccionan y los pro-blemas que estas construcciones presentan en la traducción.Abstract: This work studies the colocational field of the verb dare in Ov-id’s Metamorphoses. In Latin, it is frequent the use of a type of construction, in which a verb appears totally or partially desemanticized and the noun that selects it behaves like the predicate of the construction; it is the case of ex-amples such as: dare velas (to set sail), dare vulnera (to hurt), dare verba (to say), etc. These constructions, known as support verb constructions (SVC), present distributional variations related to author and textual genre, and some SVC are exclusive to a specific author or genre
Building Quality Assurance into Metadata Creation: an Analysis based on the Learning Objects and e-Prints Communities of Practice
No full textThis paper challenges some of the assumptions underlying the metadata creation process in the context of two communities of practice, based around learning object repositories and open e-Print archives. The importance of quality assurance for metadata creation is discussed and evidence from the literature, from the practical experiences of repositories and archives, and from related research and practices within other communities is presented. Issues for debate and further investigation are identified, formulated as a series of key research questions. Although there is much work to be done in the area of quality assurance for metadata creation, this paper represents an important first step towards a fuller understanding of the subject.
Co-creation of affordable irrigation technology: The DARE-TU project
No full textGlobal food production needs to increase. Such an increase can come from intensified irrigated agriculture. Many current irrigation technologies are energy- and cost-intensive. Providing irrigation services instead of selling hardware addresses the (financial) reality of smallholder farmers and builds a sustainable business model rather than relying on charity. Besides the scarcity of financial resources, a multi-dimensional view of sustainability becomes possible, including sustained and guaranteed operation over time and more environmentally friendly processes (including longer life of technologies). DARE-TU improves livelihoods of rural communities by design and management of appropriate Integrated Turbine Pump (ITP)-based irrigation infrastructures through sustainable product-service systems. Accessible and affordable water services technologies enable high-value irrigated agriculture (in terms of income and nutrients), providing opportunities for the rural poor and improving food security. With users and supporting organizations, DARE-TU translates general design principles into functional prototypes providing ‘irrigation as a service’ to communities, based on sustainable business models that are cost-effective for smallholders and profit-effective for organizations and/or businesses. DARE-TU is based upon / has as core / is developed around theITP, an innovative hydraulic device, operating simultaneously as pump and turbine: the turbine provides energy to drive the pump. As ITP-hardware combines higher initial costs with much lower running costs compared to conventional fuel-based pumps, it is likely that ITP-systems are less affordable by individual farmers. As such, ITP business models are envisioned to be based on community appropriation and/or a model providing irrigation services. The DARE-TU project links knowledge institutions, private companies and NGOs in building/creating/constructing an iterative design process with inputs from users (co-creation) rather than setting technical parameters as given. In close cooperation with prospective users and support organizations, socio-economic contexts plus user preferences and challenges are translated into specifications and prototypes for users in different regions. DARE-TU’s innovative approach of Context Variation by Design (CVD) intentionally and systematically combines insights from different contexts early on in the process to develop solution directions.Water ResourcesDesign for Sustainabilit

South: a Psychometric Text Adventure
No full textSouth is an instrumental discrimination borne out of the fact that without a North there is no South. It is a navigational system created by your own networks of meaning. South is a reference axis emanating from the Southbank area of South London. It is perfectly possible to find a slippery surface, lay this book down upon it and spin it round to create a new orientation; perhaps we could call it Weast or the South East Pole as my Grandfather put it. Whatever name you choose, the particular form that your journey to this destination will take is the subject of this book. The author and publishers wish you great luck on your journey; however they would also like to point out that they cannot accept legal responsibility for any strangeness, temporal or subjective dislocation, psychogenic slippages or other oddities that might result from it
Comparing consortial repositories: a model-driven analysis
No full textThis study aims to provide a comparative assessment of different repository consortia as a reference to inform future work in the area. A review of the literature was used to identify repository consortia, and their features were compared. Three models of consortial repositories were derived from this comparison, based on their structure and aims. The consortial models were based around either: creating a shared repository for the members, developing a repository software platform or creating a metadata harvesting service to aggregate content. Using case studies of each type of repository consortium, each model was assessed in terms of its particular strengths and weaknesses. These strengths were then compared across the models to enable those considering a consortial repository project to assess which model, or combination of models, would best address their needs and to aid in project planning
The Second Death Of The Author? Immersive Book Forms Using Ar/Vr And Ai
No full textIn the 1990s much was made of hypertext, it was heralded as a new form that would revolutionise our experience of reading, in particular, much was made of interactive storytelling, the idea that readers would take power from writers and define new forms of storytelling; this notion had a brief, vivid heyday, but soon fizzled out. Now, with AR/VR and AI, are we on the brink of a real transformation in our experience of storytelling, will the future really be one in which readers become storytellers as the book converges into headsets and mobile phones? Dr Eleanor Dare will discuss these possibilities, she will talk about her own research with AR/AI book forms as well as a new course at the Royal College of Art, MA Digital Direction, which seeks to nurture the disruptive storytellers and creative leaders of the future
