Models of E-Democracy
2006
Pulished article in Communications of the Association for Information Systems, 17 (1), 818-840. Also available from the publisher: http://aisel.aisnet.org/cais/vol17/iss1/37/ Several theories of E-Democracy have been presented, and implementations of and experiments in E-Democracy emerged. However, existing literature on the subject appears rather non-comprehensive, lacking an integrated basis, for gathering knowledge in the future. After an analysis of theories of E-Democracy versus implementations reported in related literature, we address the need for a model generally absent from contemporary theoretical literature: the Partisan model of E-Democracy. We aim to simplify the current "jung…
Outer boundary conditions for Einstein's field equations in harmonic coordinates
2007
We analyze Einstein's vacuum field equations in generalized harmonic coordinates on a compact spatial domain with boundaries. We specify a class of boundary conditions which is constraint-preserving and sufficiently general to include recent proposals for reducing the amount of spurious reflections of gravitational radiation. In particular, our class comprises the boundary conditions recently proposed by Kreiss and Winicour, a geometric modification thereof, the freezing-Psi0 boundary condition and the hierarchy of absorbing boundary conditions introduced by Buchman and Sarbach. Using the recent technique developed by Kreiss and Winicour based on an appropriate reduction to a pseudo-differe…
Blue Optical Observations of Narrow Bipolar Events by ASIM Suggest Corona Streamer Activity in Thunderstorms
2020
While narrow bipolar events (NBEs) could be related with lightning initiation, their intrinsic physics remains in question. Here we report on optical measurements by the Atmosphere-Space Interactions Monitor (ASIM) on the International Space Station (ISS) of blue flashes associated with NBEs. They are observed in a narrow blue band centered at 337 nm, with no simultaneous activity at 777.4 nm, considered a strong lightning emission line. From radio waves measured from the ground, we find that 7 of 10 single-pulse blue events can be identified as positive NBEs. The source altitudes estimated from optical and radio signals agree and indicate that the sources of the blue flashes are located be…
Assessing genetic structure and diversity of airborne bacterial communities by DNA fingerprinting and 16S rDNA clone library
2005
Abstract The density, genetic structure and diversity of airborne bacterial communities were assessed in the outdoor atmosphere. Two air samples were collected on the same location (north of France) at two dates (March 2003 (sample1) and May 2003 (sample 2)). Molecular culture-independent methods were used to characterise airborne bacterial communities regardless of the cell culturability. The automated-ribosomal intergenic spacer analysis (A-RISA) was performed to characterise the community structure in each sample. For both sampling dates, complex A-RISA patterns were observed suggesting a highly diverse community structure, comparable to those found in soil, water or sediment environment…
Los sistemas de información y la auditoría informática aplicados a una institución fiscalizadora subestatal: la Sindicatura de Comptes de la Comunida…
2020
La digitalización es un fenómeno global que afecta a todas las actividades humanas. Las administraciones públicas también han incorporado a sus estructuras las nuevas tecnologías de la información y la comunicación, de manera que el sector público se ha informatizado completamente. En este contexto digital, la auditoría informática es una herramienta que permite fiscalizar las administraciones públicas y, a la vez, mejora la rendición de cuentas. Este artículo examina las principales ventajas y riesgos de la digitalización y ofrece un estudio de caso centrado en una institución fiscalizadora pública española que ha implementado la auditoría informática para auditar todas las operaciones de …
Using continuous user authentication to detect masqueraders
2003
Nowadays computer and network intrusions have become more common and more complicated, challenging the intrusion detection systems. Also, network traffic has been constantly increasing. As a consequence, the amount of data to be processed by an intrusion detection system has been growing, making it difficult to efficiently detect intrusions online. Proposes an approach for continuous user authentication based on the user’s behaviour, aiming at development of an efficient and portable anomaly intrusion detection system. A prototype of a host‐based intrusion detection system was built. It detects masqueraders by comparing the current user behaviour with his/her stored behavioural model. The m…

Website localization towards the Norwegian market : an analysis of American firm´s websites
2011
Masteroppgave i økonomi og administrasjon - Universitetet i Agder 2011 - Masteroppgave i informasjonssystemer- Universitetet i Agder 2011 This study is the first involving international firms and the localization of firms' websites for a Norwegian audience. In order to give the reader a better understanding of the topic, we first conducted a literature review where we identified five key themes related to website localization: standardization versus localization, localization website design characteristics, website localization measurement and cultural depictions in websites. The research method used in this thesis is a quantitative analysis of data collected via the content analysis of web…
