Clustering Questions in Healthcare Social Question Answering Based on Design Science Theory
No full textIn healthcare social media, users connect with patients and professionals without time and space boundaries to seek and share healthcare-related information (Denecke and Stewart 2011). A classic example of a Medicine 2.0 application is a healthcare Social Question Answering (SQA) service. Healthcare SQA services are redefining healthcare delivery and supporting patient empowerment. Healthcare SQA services allow users to seek information, communicate with others on similar problems, share health guidance, and compare treatment and medication strategies (Blooma and Wickramasinghe 2014). Examples of healthcare SQA services are MedHelp, BabyHub, and Drugs.com . The growing activities in online healthcare communities, asking questions and sharing answers, play an important role in users’ health information inquiries (Zhang and Zhao 2013). Individual behaviors, in particular health-related behaviors such as physical activity, diet, sleep, smoking, and alcohol consumption, as well as adherence to medical treatments and help-seeking behavior (Hyyppä 2010), appear to be significant in SQA services<br/
A pervasive technology solution for supporting diabetes self-care
No full textTo date, the adoption and diffusion of technology-enabled solutions to deliver better healthcare has been slow. There are many reasons for this. One of the most significant is that existing methodologies that are normally used in general for information communication technology (ICT) implementations tend to be less successful in a healthcare context. This chapter describes a knowledge-based adaptive mapping to realization methodology that provides a means to traverse from idea to realization rapidly and yet without compromising rigor so that success ensues. It is discussed in connection with trying to implement superior ICT-enabled approaches for facilitating superior chronic disease management.Nilmini Wickramasinghe, Indrit Troshani and Steve Goldber
DiaMonD: Developing a diabetes monitoring device in the australian context
No full textDiabetes is one of the leading chronic diseases affecting Australians and its prevalence continues to rise. Diabetes is therefore becoming a serious challenge for both the quality of healthcare and expenditure in the Australian healthcare system. The goal of this study is to investigate the development and application of DiaMonD – a diabetes monitoring device. Powered by pervasive technology software developed by INET, DiaMonD is a wireless enabled mobile phone that can facilitate superior diabetes selfmanagement. The development and application of DiaMonD using the Adaptive Mapping to Realisation methodology (AMR) methodology is examined in addition to an appraisal of key adoption facilitators and barriers in the Australian setting.Nilmini Wickramasinghe and Indrit Troshani, Steve Goldberghttp://aisel.aisnet.org/bled2010/26
A pervasive wireless knowledge management solution to address urban health inequalities with indigenous Australians
No full textA recent study by Adelaide Aboriginal and Torres Strait Islander Health (Gallagher et al., In our own backyard: Urban health inequalities and Aboriginal experiences of neighbourhood life, social capital and racism, 2009) revealed some alarming findings concerning the health status of these groups. One of the key health areas that requires attention is that of chronic diseases in general and diabetes in particular. We propose using a wireless knowledge-based system developed by INET for enabling effective and efficient monitoring of patients with diabetes. We argue that systematic use of this solution can improve self-management and lead to positive healthcare outcomes. Key aspects of the wireless diabetes solution to facilitate self-management of diabetes patients are highlighted. Adoption facilitators and barriers, assessment criteria, and policy implications are discussed.Nilmini Wickramasinghe, Indrit Troshani and Steve Goldber
Handbook of Accounting and Development
No full text'Trevor Hopper and his colleagues provide a central point of reference for research into accounting and development. Definitive chapters from internationally recognised authors (including Marcia Annisette, Kerry Jacobs, Chris Poullaos, Brendan O'Dwyer, Chibuike Uche and Jeffrey Unerman) cover the full range of issues from the role of capital markets in development, through accounting professionalization, to taxation and transfer pricing. Contributions from authors working for donors and non-governmental organisations provide a useful practical dimension that builds on the more academic chapters.' - Christopher Napier, Royal Holloway, University of London, UK. © Trevor Hopper, Mathew Tsamenyi, Shahzad Uddin and Danture Wickramasinghe 2012.

Small <i>R. erangaviraji</i> have been found readily during October to January. The colour pattern of these younger animals is as in adults, with overall paler colours but a much darker head (Fig 12). Paratype NMSL20080604 has seven maxillary and seven mandibular teeth on each side.</p> <p> <b>Etymology:</b> Named for the late Mr. Eranga Viraj Dayarathne, an Instructor of the Reptiles group of the Young Zoologists’ Association of Sri Lanka, Department of National Zoological Gardens. A man who showed love and kindness to nature, and quiet yet effective service to Sri Lankan reptiles and their conservation. Suggested vernacular names: <i>Eranga Virajge thudulla, Eranga Virajvin nilakael pambu, Eranga Viraj’s shieldtail snake</i> (or <i>Eranga Viraj's</i> Rhinophis) in Sinhala, Tamil, and English respectively.</p> <p> <b>Comparison:</b> Apart from the listed diagnostic characters, <i>R. erangaviraji</i> can be distinguished further from all other Sri Lankan congeners in details of its colour pattern. <i>Rhinophis dorsimaculatus</i> has a broad orange, middorsal vertebral stripe (vs black dorsal body colour); <i>R. drummondhayi</i> has a dappled brown and white or pale yellow venter (vs black with yellow), a whitish (vs black) anal region and a yellow-white ring at the base of the tail (vs absent); <i>R. homolepis</i> has a white/yellow collar behind the head (vs dorsal surface of neck black), white/yellow triangular (apex pointed upwards) markings along body (vs scalloped yellow stripe), yellow anal (vs black), and pale yellow ring at base of tail (vs absent); <i>R. oxyrhynchus</i> has a uniformly brown dorsal colour (vs black), pale brown to yellow or whitish venter (vs black with yellow), and yellow anal (vs black); <i>R. philippinus</i> has a purplish-black dorsum (vs black) and lateral and ventral surface of body (vs black with yellow markings); <i>R. porrectus</i> and <i>R. punctatus</i> have a whitish venter (vs black), and a narrow dark dorsal stripe (vs no stripe); <i>R. tricoloratus</i> has a yellow to yellow-brown venter (vs black with yellow markings), gray to brown dorsum (vs black), yellow to whitish yellow anal (vs black), and a yellowish ring at base of tail (vs absent).</p> <p> <b>Habitat, Ecology and Conservation:</b> <i>Rhinophis erangaviraji</i> and <i>R. blythii</i> are allopatric, with the former known only from the Rakwana massif and the latter from the Central Hills, of Sri Lanka. <i>Rhinophis erangaviraji</i> can be found without difficulty in loose soil in shady areas, up to 1 m deep, under leaf litter in drainage ditches in tea estates, home gardens, and grasslands, but is also relatively commonly seen within the natural forest habitat of Rakwana. At night these snakes can be seen in the leaf litter. Probable conservation threats to this species are habitat loss, and deterioration caused by agriculture (especially tea), including the use of agrochemicals. Forest fires started by humans during the dry season are another threat, as indicated by many dead specimens being found after these fires. Road kills have also been observed.</p>Published as part of <i>Mendis Wickramasinghe, L. J., Vidanapathirana, Dulan Ranga, Wickramasinghe, Nethu & Ranwella, P.

Natural History. Aspidura desilvai sp. nov. have been observed commonly in its habitat (Figure 1). The species is confined to Knuckles conservation area, and is found in and above the lower montane forests of Knuckles. Authors have observed the snake from 995 m up to 1700 m above sea level (Figure 8). The habitat of A. desilvai sp. nov. is closed canopy forests dominated by Syzigium sp. (Figure 9). The moist-cooler habitat is densely occupied with large and medium sized trees which are heavily covered with epiphytes. No direct sunlight falls to the forest floor, and the undergrowth was not well established where the individuals were found. Relatively thin litter cover was observed in the habitat. Commonly observed under leaf litter and loose soil while they were also observed under rocks, boulders, and decaying logs. Individuals come out to the surface during the day time. Reddish brown latosolic soil in the locality is more or less similar to the body colour of the snake. Etymology. The species is named in honor of Pilippu Hewa Don Hemasiri de Silva (Dr. P. H. D. H. de Silva), a former Director (1965-1981) of the National Museums of Sri Lanka. In recognition of his tireless services to the country, while in service and through his many publications specially as the author of the book titled “ Snake Fauna of Sri Lanka, with special reference to skull, dentition and venom in snakes ”. The species epithet desilvai is a noun in the genitive case. Suggested common names. desilvage madilla, and de Silva’s Rough-Side Snake in native Sinhala language and English language respectively. Comparison. The new species was compared with all known congeners of the genus Aspidura and the species most closely resembles A. ravanai, and A. trachyprocta, due to the following combination of characters: one preocular, two postoculars, 1+2 temporals, supralabials 6, 4 th supralabial in contact with the eye, infralabials 6, coastals 15, single cloacal scale, and overlapping ventral and subcaudal counts, but can easily be distinguished by the following morphological characters: from A. ravanai: entire dorsum brown colour, much paler towards anterior and each scale having tiny dark spots in Aspidura desilvai sp. nov. (vs. entire dorsum jet black in Aspidura ravanai), ventrolaterally darker region which constitutes of irregular longitudinal dotted lines (vs. ventrolaterally an irregular longitudinal yellow stripe), laterally prominent spine like tubercles present on two scale rows nearest to the subcaudals, and its protrusion reducing towards upper scale rows (vs. entire coastal rows coarsely keeled, with 1–3 peaks on each scale) in males (Figures 4 & 10 A–C), entire coastal rows of the ischiadic, anal and tail base regions smooth (vs. feebly keeled) in females, snout to eye distance about 2.5 times its eye width (vs. 3.2 times in A. ravanai) (Figures 3 & 10 D–E); from Aspidura trachyprocta: entire dorsum brown colour, much paler towards anterior and each scale having tiny dark spots in A. desilvai sp. nov. (vs. reddish-yellow to brown with a longitudinal black stripe on mid dorsum in Aspidura trachyprocta), ventrolaterally darker region which constitutes of irregular longitudinal dotted lines (vs. black stripe), laterally prominent spine like tubercles present on two scale rows nearest to the subcaudals, and its protrusion reducing towards upper scale rows (vs. bulging spine like tubercles prominent laterally which reduces towards dorsum) of the ischiadic, anal and tail base regions in males (Figures 4 & 11 A–C), entire coastal rows of the ischiadic, anal and tail base regions smooth (vs. feebly keeled) in females, snout to eye distance about 2.5 times its eye width (vs. twice in A. trachyprocta) (Figures 3 & 11 D–E); from A. brachyorrhos Boie, 1827, by having 15 coastals (vs. 17), preocular not in contact with supraocular (vs. contact), prefrontal contact with eye (vs. separate), single subcaudals (vs. paired); from A. copei Günther, 1864 by having coastals 15 (vs. 17), single subcaudals (vs. paired), single preocular (vs. absent); from A. deraniyagalae Gans & Fetcho, 1982 by having 15 coastals (vs. 17), ventrals 124–139 (vs. 117–122), single subcaudals (vs. paired); from A. drummondhayi Boulenger, 1904, by having single subcaudals (vs. paired), single preocular (vs. absent); from A. guentheri Ferguson, 1876 by having 15 coastals (vs. 17), ventrals 124–139 (vs. 100–127); from A. ceylonensis (Günther, 1858), by prefrontal touching eye (vs. not touching eye), preocular does not touch supraocular (vs. touches), lower postocular larger than the upper (vs. vise versa), mid body coastals not keeled (vs. coarsely keeled).Published as part of Mendis Wickramasinghe, L.
