Northward range expansion requires synchronization of both overwintering behaviour and physiology with photoperiod in the invasive Colorado potato be…
2014
Abstract. Photoperiodic phenological adaptations are prevalent in many organisms living in seasonal environments. As both photoperiod and growth season length change with latitude, species undergoing latitudinal range expansion often need to synchronize their life cycle with a changing photoperiod and growth season length. Since adaptive synchronization often involves a large number of time-consuming genetic changes, behavioural plasticity might be a faster way to adjust to novel conditions. We compared behavioural and physiological traits in overwintering (diapause) preparation in three latitudinally different European Colorado potato beetle (Leptinotarsa decemlineata) populations reared u…
Temperature dependence of η / s of strongly interacting matter: Effects of the equation of state and the parametric form of ( η / s ) ( T )
2020
We investigate the temperature dependence of the shear viscosity to entropy density ratio η/s using a piecewise linear parametrization. To determine the optimal values of the parameters and the associated uncertainties, we perform a global Bayesian model-to-data comparison on Au+Au collisions at √sNN=200 GeV and Pb+Pb collisions at 2.76 TeV and 5.02 TeV, using a 2+1D hydrodynamical model with the Eskola-Kajantie-Ruuskanen-Tuominen (EKRT) initial state. We provide three new parametrizations of the equation of state (EoS) based on contemporary lattice results and hadron resonance gas, and use them and the widely used s95p parametrization to explore the uncertainty in the analysis due to the c…
Les modèles de communication des sciences et techniques, révélateurs de postures publiques
2012
In addition to the famous deficit and contextual models scientific literature on science communication offers a wide variety of models, seen as mental, textual or pictural representations, helpful to describe, to explain, to analyze, to act. The models I found can be listed by themes: institutional questions, cultural visions, mediation, mass media, epistemology, teaching tools, advertising... Then, the pervasiveness of deficit and contextual models in the meetings dealing with scientific culture can be analyzed as a focus on institutional concerns, based on the need of effective communication ways. But exploring the models utilized by science communication scholarships, in all their multif…
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…

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 …
