    Exploring ā€˜eventsā€™ as an information systems research methodology

    This paper builds upon existing research and commentary from a variety of disciplinary sources including Information Systems, Organisational and Management Studies, and the Social Sciences that focus upon the meaning, significance and impact of ā€˜eventsā€™ in both an organisational and a social sense. The aim of this paper is to define how the examination of the event is an appropriate, viable and useful Information Systems methodology. Our argument is that focusing on the ā€˜eventā€™ enables the researcher to more clearly observe and capture the complexity, multiplicity and mundaneity of everyday lived experience. The use and notion of ā€˜eventā€™ has the potential to reduce the methodological dilemmas associated with the micromanagement of the research process ā€“ an inherent danger of traditional and ā€˜virtual' ethnographic approaches. Similarly, this paper addresses the over-emphasis upon managerialist, structured and time-fixated praxis that is currently symptomatic of Information Systems research. All of these concerns are pivotal points of critique found within eventoriented literature. An examination of event-related theory within interpretative disciplines directs the focus of this paper towards the more specific realm of the ā€˜event sceneā€™. The notion of the ā€˜event sceneā€™ originated in the action based (and anti-academy) imperatives of the Situationists and emerged in an academic sense as critical situational analysis. Event scenes are a focus for contemporary critical theory where they are utilised as a means of representing theoried inquiry in order to loosen the restrictions that historical and temporally bound analysis imposes upon most interpretative approaches. The use of event scenes as the framework for critiquing established conceptual assumptions is exemplified by their use in CTheory. In this journal's version and articulation of the event scene poetry, commentary, multi-vocal narrative and other techniques are legitimated as academic forms. These various forms of multi-dimensional expression are drawn upon to enrich the understandings of the ā€˜eventā€™, to extricate its meaning and to provide a sense of the moment from which the point of analysis stems. The objective of this paper is to advocate how Information Systems research can (or should) utilize an event scene oriented methodology

    Photovoltaic system costs using local labor and materials in developing countries

    The use of photovoltaic (PV) technology in countries that do not presently have high technology industrial capacity was investigated. The relative cost of integrating indigenous labor (and manufacturing where available) into the balance of the system industry of seven countries (Egypt, Haiti, the Ivory Coast, Kenya, Mexico, Nepal, and the Phillipines) was determined. The results were then generalized to other countries, at most levels of development. The results of the study imply several conclusions: (1) the cost of installing and maintaining comparable photovoltaic systems in developing countries is less than in the United States; (2) skills and some materials are available in the seven subject countries that may be applied to constructing and maintaining PV systems; (3) there is an interest in foreign countries in photovoltaics; and (4) conversations with foreign nationals suggest that photovoltaics must be introduced in foreign markets as an appropriate technology with high technology components rather than as a high technology system

    From search engine optimisation to search engine marketing management: development of a new area for information systems research

    Get PDF
    Search Engine Optimisation was a term used by web developers in the late 90s to highlight the importance of increasing a websiteā€™s position in search enginesā€™ results. Further development of the Internet in terms of the diversity of its users and uses such as e-commerce, blogging and wikis have highlighted the need for technical staff to work more closely with marketing professionals resulting in a new area of work ā€“ Search Engine Marketing Management. The paper highlights the emerging role of Search Engine Marketing Management as a new and increasingly important area for future information systems researchers and research. Reaching beyond the 'simple' undifferentiated goal of increasing visitors to a website, a mature perspective of marketing is developing - that of realising strategic marketing objectives. The practical contribution of this paper is found in the development of awareness among management roles of the importance and nuances of search engines and the tactics required to harness the benefits of multiple online communication channels within organisational marketing strategy

    Mandatory public benefit reporting as a basis for charity accountability: findings from England & Wales

    Get PDF
    Charitable status is inherently linked in many jurisdictions with the requirement that an entity must be established for public benefit. But, until recently the public benefit principle had relatively little impact on the operations of most established charities. However, in England and Wales, reforms linked to the Charities Act 2006 led to a new requirement for public benefit reporting in the trusteesā€™ annual report (TAR) of every registered charity. This new narrative reporting requirement had the potential to affect the understanding of accountability by charities. The paper investigates the impact of that requirement through a study of over 1400 sets of charity reports and account

    Induction of dark-adaptive retinomotor movement (cell elongation) in teleost retinal cones by cyclic adenosine 3,5-monophosphate.

    In the teleost retina, the photoreceptors and retinal pigment epithelium (RPE) undergo extensive movements (called retinomotor movements) in response to changes in light conditions and to an endogenous circadian rhythm. Photoreceptor movements serve to reposition the light-receptive outer segments and are effected by changes in inner segment length. Melanin granule movements within the RPE cells provide a movable melanin screen for rod outer segments. In the dark (night), cones elongate, rods contract, and pigment granules aggregate to the base of the RPE cell; in the light (day), these movements are reversed. We report here that treatments that elevate cytoplasmic cyclic adenosine 3,5-monophosphate (cAMP) provoke retinomotor movements characteristic of nighttime dark adaptation, even in bright light at midday. To illustrate this response, we present a quantitative description of the effects of cyclic nucleotides on cone length in the green sunfish, Lepomis cyanellus. Cone elongation is induced when light-adapted retinas are exposed to exogenous cAMP analogues accompanied by phosphodiesterase (PDE) inhibitors (either by intraocular injection or in retinal organ culture). Cone movements is not affected by cyclic GMP analogies. Dose-response studies indicate that the extent, but not the rate, of cone elongation is proportional to the concentration of exogenous cAMP and analogue presented. As has been reported for other species, we find that levels of cAMP are significantly higher in dark- than in light-adapted green sunfish retinas. On the basis of these observations, we suggest that cAMP plays a role in the light and circadian regulation of teleost cone length
