Grammaire et méthodes de fle : enquêtes sur les constructions infinitives de perception
2022
Through our observations of classroom practices, as didacticians and linguists, we notę that infinitive constructions govemed by a verb of perception (1CP) are only extremely rarely included in French as a Foreign Language teaching programmes. Yet, the perception of reality through the senses is one of the sociolinguistic objectives. In this case, unless we are inattentive, this is a notable gap in didactics that should be filled. We would propose to elucidate the specificities of the French ICP from a semantic-logical and cognitive perspectives.
Empowering team leadership and safety performance in nuclear power plants: A multilevel approach
2013
Abstract Despite the large body of work on team leadership, hardly any literature has dealt with team leadership in safety performance settings. The goal of the present study is to analyze how team leader behaviors influence team members’ safety performance in nuclear power plants. For this purpose, an empowering leadership approach was assessed. We consider a multilevel model in which safety performance is divided into three types of behaviors. The sample was composed of 479 workers in 54 groups from two Spanish nuclear power plants. The results suggested that leaders’ empowering behaviors generated higher safety compliance behaviors and higher safety participation behaviors by team member…
A person-environment-fit-model for temporary organizations - Antecedents for temporary working settings
2021
Abstract Projectification has led to the widespread use of temporary organizations (TOs) in many industries, but the various factors that determine successful work by employees in TOs are unexplored. We argue that organizations have different degrees of temporariness depending on the following five TO dimensions: temporal duration, nature of the task, team composition, hierarchy, and coordination. Considering the TO dimensions and varying degrees of temporariness, we propose a person-environment (P-E) fit model. The model comprises three levels – organizational-, group-, and job-oriented – and relates personal attributes to the TO dimensions. We contribute to theory by developing a set of p…
I am right here with you - Constructing presence in distributed teams
2013
Based on a naturalistic research approach and observational data from real-life distributed teamwork, this paper illustrates how members of virtual teams in today's knowledge-intensive work places can construct and negotiate (social) presence together. Instead of seeing presence as an individual's interpretation and linking it with perceptual illusion of non-mediation or the assumed traits of chosen communication media, this paper sees presence as being socially constructed in interaction. The paper offers critique towards existing models of computer-mediated presence and offers new directions for research.
Which are the patterns of video game use in Spanish school adolescents? Gender as a key factor
2020
Abstract Video games are part of the technological revolution, and it is possible nowadays to play video games anytime and anywhere as a primary source of youth entertainment. The research question of this study refers to which are the patterns of video game usage by Spanish school adolescents. In particular, it analyzes the time and money spent on video games among Spanish teenage students of 11–19 years old (M = 13.98; SD ± 1.397), as well as the game platform and the type of video games used, according to type of day and, especially, gender of the player. A survey was applied to a representative sample of adolescent students (n = 1502) from Valencian Region (Spain). The results showed an…
Maturation of critical technologies for the DEMO balance of plant systems
2022
The Pre-Concept Design (PCD) of the Balance of Plant (BoP) systems of the EU-DEMO power plant is described in this paper for both breeding blanket (BB) concepts under assessment, namely the Water Cooled Lithium Lead (WCLL) BB and the Helium Cooled Pebble Bed (HCPB) BB. Moreover, the results of a preliminary evaluation of a number of BoP variants are discussed. This paper outlines the steps of the BoP design development, highlighting the project objectives and the strategy for their achievement under the very challenging requirements which include, among others, the intermittent nature of the DEMO plasma heat source. The main achievements during the PCD Phase will be reported together with t…
Electric Mobility in Portugal: Current Situation and Forecasts for Fuel Cell Vehicles
2021
In recent years, the growing concern for air quality has led to the development of sustainable vehicles to replace conventional internal combustion engine (ICE) vehicles. Currently, the most widespread technology in Europe and Portugal is that of Battery Electric Vehicles (BEV) or plug‐in HEV (PHEV) electric cars, but hydrogen‐based transport has also shown significant growth in the commercialization of Fuel Cell Electric Vehicles (FCEV) and in the development of new infrastructural schemes. In the current panorama of EV, particular attention should be paid to hydrogen technology, i.e., FCEVs, which is potentially a valid alternative to BEVs and can also be hybrid (FCHEV) and plug‐in hybrid…
INVESTIGATION OF THE UNDERGROUND BUILDING HERITAGE AND THE MECHANISM OF WATER FLOWING IN QANĀTS IN PALERMO THROUGH INNOVATIVE SURVEYING TECHNIQUES
2021
Abstract. The valorisation, protection and preservation policies for the underground building heritage are often difficult to implement due to an inadequate knowledge of hypogeal constructions. The complex and widespread underground structures of the vast “Cavo” Heritage (“horizontal wells”, “shelf wells” or “well tunnels”), so called qanāts, hidden underground and built over the centuries in Palermo, representing an evocative testimony to the history of water culture in the ancient city. Through the historical and constructive analyses and the implementation and development of measurement and 3D representation and visualization, first actions have been carried out. The paper will present t…
Integrating topographic, photogrammetric and laser scanning techniques for a scan-to-bim process
2021
Abstract. The preservation of historic buildings can often be particularly difficult due to the lack of detailed information about architectural features, construction details, etc.. However, in recent years considerable technological innovation in the field of Architecture, Engineering, and Construction (AEC) has been achieved by the Building Information Modeling (BIM) process. BIM was developed as a methodology used mainly for new construction but, given its considerable potential, this approach can also be successfully used for existing buildings, especially for buildings of historical and architectural value. In this case, it is more properly referred to as Historic – or Heritage – Buil…
Integrated design of breeding blanket and ancillary systems related to the use of helium or water as a coolant and impact on the overall plant design
2021
Currently, for the EU DEMO, two Breeding Blankets (BBs) have been selected as potential candidates for the integration in the reactor. They are the Water Cooled Lithium Lead and the Helium Cooled Pebble Bed BB concepts. The two BB variants together with the associated ancillary systems drive the design of the overall plant. Therefore, a holistic investigation of integration issues derived by the BB and the installation of its ancillary systems has been performed. The issues related to the water activation due to the 16N and 17N isotopes and the impact on the primary heat transfer systems have been investigated providing guidelines and dedicated solution for the integration of safety devices…
