Individuals’ Use of E-Mail Communication Genres in Open Source Software Community Building
2011
The advent of the participative Internet (Web 2.0) sheds a new light on traditional knowledge about communication practices. The role of information and communication technologies seems to be very central in managerial literature, while the human side of the issue is less considered. This paper argues that individuals establish communication genres as semantic templates for accomplishing their communicative projects. Communication genres are codes of default behavioral expectations resulting from recurrent communication actions over the time. By using semantic network analytical techniques, our argument is explored in a particular empirical setting, that is, a virtual community of open sour…

Miejsce i znaczenie oceny jakości informacji w wybranych modelach ewaluacji bibliotek cyfrowych
2016
Teza/cel artykułu - Zapewnienie odpowiedniej jakości zasobów informacji w bibliotekach cyfrowych stanowi nowe wyzwanie dla dalszego intensywnego rozwoju tego rodzaju wirtualnych organizacji. Celem artykułu jest ukazanie miejsca i znaczenia oceny jakości informacji w najważniejszych modelach ewaluacji bibliotek cyfrowych. Metody - Jako metodę badawczą zastosowano analizę porównawczą wybranych modeli bibliotek cyfrowych pod względem sposobu ujęcia oceny jakości informacji w strukturze modelu, zakresu tej oceny oraz proponowanych metod i technik oceny. Wyniki/ wnioski - W badanych modelach przedmiotem oceny były zarówno dane, jak i metadane. Przeprowadzona analiza wykazała także, że rozważane …
Il report del capitale intellettuale nel settore non profit: esperienze a confronto
2010
Il contributo si interroga sulla possibilità, da parte degli stakeholder di un’organizzazione, di capire il processo di creazione del valore dalla lettura del suo report del CI. La research question (RQ) al centro del paper è pertanto la seguente :RQ I modelli evoluti di report del CI riescono ad evidenziare il ruolo giocato dagli intangibili nel processo di creazione del valore aziendale?L’approccio metodologico seguito nel paper per rispondere alla RQ è quello di un confronto sistematico tra due report del CI di due differenti organizzazioni, uno appartenente ai modelli pionieristici di rendicontazione del CI, l’altro ai modelli evoluti, dal momento che, nella realtà, modelli pionieristic…
The Aqua-Planet Experiment (APE): Response to Changed Meridional SST Profile
2013
This paper explores the sensitivity of Atmospheric General Circulation Model (AGCM) simulations to changes in the meridional distribution of sea surface temperature (SST). The simulations are for an aqua-planet, a water covered Earth with no land, orography or sea- ice and with specified zonally symmetric SST. Simulations from 14 AGCMs developed for Numerical Weather Prediction and climate applications are compared. Four experiments are performed to study the sensitivity to the meridional SST profile. These profiles range from one in which the SST gradient continues to the equator to one which is flat approaching the equator, all with the same maximum SST at the equator. The zonal mean circ…
Business models in Spanish industry : a taxonomy-based efficacy analysis
2010
The present study provides a conceptualization of the business model construct from which a multi-dimensional evaluation tool is developed that provides the basis for drawing up a taxonomy and analysing its comparative efficacy. The empirical data was obtained from a sampling of 159 Spanish business organisations. The cluster analysis revealed the existence of four business models that were designated as “multidivisional”, “integrated”, “hybrid” and “network”. The results also indicate that the adoption of a certain business model is not enough to attain superior performance, highlighting the need to consider other contingent factors.
CHANGING PERSPECTIVE ON PERCEPTION PHYSIOLOGY: CAN YOU REALLY SEE WHAT IS HAPPENING?
2018
Perception is a complex, neural mechanism that requires organization and interpretation of input meaning and it has been a key topic in medicine, neuroscience and philosophy for centuries. Gestalt psychology proposed that the underlying mechanism is a constructive process that depends on both input of stimuli and the sensory-motor state of the agent. The Bayesian Brain hypothesis reframed it as probabilistic inference of previous beliefs, which are revised to accommodate new information. The Predictive Coding Theory proposes that this process is implemented through a top-down cascade of cortical predictions of lower level input and the concurrent propagation of a bottom-up prediction error …
HOWERD: A Hidden Markov Model for Automatic OWL-ERD Alignment
2016
The HOWERD model for estimating the most likely alignment between an OWL ontology and an Entity Relation Diagram (ERD) is presented. Automatic alignment between relational schema and ontology represents a big challenge in Semantic Web research due to the different expressiveness of these representations. A relational schema is less expressive than the ontology; this is a non trivial problem when accessing data via an ontology and for ontology storing by means of a relational schema. Existent alignment methodologies fail in loosing some contents of the involved representations because the ontology captures more semantic information, and several elements are left unaligned. HOWERD relies on a…

Information Transfer in Linear Multivariate Processes Assessed through Penalized Regression Techniques: Validation and Application to Physiological N…
2020
The framework of information dynamics allows the dissection of the information processed in a network of multiple interacting dynamical systems into meaningful elements of computation that quantify the information generated in a target system, stored in it, transferred to it from one or more source systems, and modified in a synergistic or redundant way. The concepts of information transfer and modification have been recently formulated in the context of linear parametric modeling of vector stochastic processes, linking them to the notion of Granger causality and providing efficient tools for their computation based on the state&ndash
