Negotiating the symbolic power of information and communication technologies (ICT): The spread of Internet-supported distance education
2009
Submitted version of an article in the journal: Information Technology for Development The deposited fulltext is a preprint of the definitive article at Wiley Interscience http://dx.doi.org/10.1002/itdj.20110 The Internet may be, as typically suggested, important in distance education for facilitating connections between groups of students, educational institutions, and external learning resources. This article, however, reveals why this is not the only reason for applying information and communication technologies (ICT) in higher education in a remote area in a developing country. In addition, the Internet seems to be of great importance in symbolizing modernization and progress, thereby a…
Agility and system documentation in large-scale enterprise system projects: a knowledge management perspective
2021
Abstract The growth of the agile approach usage comes with a deemphasis on formal documentation (explicit knowledge) and an increased reliance on personal interactions (tacit knowledge) for knowledge transfer. However, the sharing of tacit knowledge poses challenges. The agile approach is prone to knowledge hoarding, as well as knowledge loss from employee turnover and reassignment during periods of significant organizational changes. This study proposes a model that frames documentation and personal interactions as co-agents of system knowledge transfer. We report the preliminary confirmation of crucial antecedents along the dimensions of codification and personalization strategies to supp…
Reply to the “Comment by Delmelle et al. (2013) on ‘Scavenging of sulfur, halogens and trace metals by volcanic ash: The 2010 Eyjafjallajökull erupti…
2014
Abstract With this short communication we address the principal issues raised by Delmelle et al. (2014) in relation to the work of Bagnato et al. (2013) concerning the 2010 eruption of Eyjafjallajokull, Iceland. The principal conclusions of the work of Bagnato et al. (2013) include the observation that protracted gas-aerosol interaction in the plume promotes selective leaching of cation species from ash, with alkalis and Ca (and, among trace elements, Zn and Cu) being more rapidly re-mobilized (and transferred to soluble surface salts) relative to more inert elements (Mg, Ti). They also observed that adsorption onto ash surfaces is a major atmospheric sink of volcanic acidic gases, with 282…
Yttrium and lanthanides in human lung fluids, probing the exposure to atmospheric fallout.
2011
International audience; Inhalation of airborne particles can produce crystallization of phosphatic microcrysts in intraaveolar areas of lungs, sometimes degenerating into pulmonary fibrosis. Results of this study indicate that these pathologies are induced by interactions between lung fluids and inhaled atmospheric dust in people exposed to volcanic dust ejected from Mount Etna in 2001. Here, the lung solid-liquid interaction is evaluated by the distribution of yttrium and lanthanides (YLn) in fluid bronchoalveolar lavages on selected individuals according the classical geochemical approaches. We found that shale-normalised patterns of yttrium and lanthanides have a 'V shaped' feature corre…
Solving Two-Person Zero-Sum Stochastic Games With Incomplete Information Using Learning Automata With Artificial Barriers
2021
Learning automata (LA) with artificially absorbing barriers was a completely new horizon of research in the 1980s (Oommen, 1986). These new machines yielded properties that were previously unknown. More recently, absorbing barriers have been introduced in continuous estimator algorithms so that the proofs could follow a martingale property, as opposed to monotonicity (Zhang et al., 2014), (Zhang et al., 2015). However, the applications of LA with artificial barriers are almost nonexistent. In that regard, this article is pioneering in that it provides effective and accurate solutions to an extremely complex application domain, namely that of solving two-person zero-sum stochastic games that…
Effects of agricultural drainage systems on sediment connectivity in a small Mediterranean lowland catchment
2018
Traditional drainage systems combining man-made channels and subsurface tile drains have been used since Roman times to control water excess in Mediterranean lowland regions, favouring adequate soil water regime for agriculture purposes. However, mechanization of agriculture, abandonment or land use changes lead to a progressive deterioration of these drains in the last decades. The effects of these structures on hydrological and sediment dynamics have been previously analyzed in a small Mediterranean lowland catchment (Can Revull, Mallorca, Spain, 1.4 km2) by establishing an integrated sediment budget with a multi-technique approach. Moreover, the recent advances in morphometric techniques…
Developing human/AI interactions for chat-based customer services: lessons learned from the Norwegian government
2022
Advancements in human/AI interactions led to smartification of public services via the use of chatbots. Here, we present findings from a clinical inquiry research project in a key public service organisation in Norway. In this project, researchers and practitioners worked together to generate insights on the action possibilities offered to human service agents by chatbots and the potential for creating hybrid human/AI service teams. The project sensitised service agents to discover affordances based on their actual practices, rather than on the predefined use of chatbots. The different affordances identified can be useful for practitioners who design and deploy chatbot-based services. The a…
The dead wrote their memory: Postmemory and metafiction in 21st century Europe
2019
Tanto en España como en Alemania el discurso público oficial se ha debatido entre el recuerdo de las víctimas y un necesario olvido con la vista puesta en el futuro. La literatura ha asumido en general la responsabilidad de mantener viva la memoria de los muertos que la traumática historia del siglo xx dejó en Europa. Las obras de Alberto Méndez y Michel Bergmann reflejan ese pasado en el marco de una “postmemoria” propia de los descendientes de la generación de los testigos. La fuerza del testimonio de estos se incorpora a los textos Manuscrito encontrado en el olvido (2004) y Weinhebers Koffer (2015) a través de la metaficción, convertida en un recurso que permite dotar de voz a los muert…
