Apprendre à manger. Sémiotique des objets de table pour enfants

2021

The subject of children at the table is related to that of conviviality on two levels. Firstly, at the level of the acquisition of social rules concerning the ways of being at the table, the codes of the meal, the recognition of appropriate behaviour in different contexts (at home, outside, formal, informal, etc.), in short, the "have to". Secondly, at the level of the acquisition of a general know-how, represented by all the somatic behaviours necessary for the consumption of the meal: learning to chew solid food, to drink from a glass, to use cutlery, to handle plates, bowls, soup plates, and so on. In this essay, we will analyse table objects designed for children (glasses, cutlery, plat…

Players' progression through GraphoGame, an early literacy game: Influence of game design and context of play

2019

Researchers of serious games frequently investigate outcomes of play but overlook the underlying game-design components that drive those outcomes. In this paper, I aim to show how game design and context of play influence progression through GraphoGame, an early-literacy game. This is done by means of two intersecting studies. The first study shows how the game can be represented by a model that explicitly hypothesizes how the interaction between the player and the game drives progression. The second study explores user data generated by first graders (N = 137) who played the game over a period of 25 weeks as part of early literacy instruction. The juxtaposition of these two studies reveals…

Modular Service Design of Information Technology-Enabled Services

2022

The literature has proposed ways to modularize information-technology-enabled services (ITeS) with limited success. We argue that applying design principles (DPs) can address this gap and revitalize the service modularization literature. With a qualitative research study, we develop exemplar DPs and a set of prioritized DPs for ITeS. We contribute to the literature by demonstrating how complex service systems, specifically ITeS, can be modularly designed. Our DPs show how different ITeS design elements or service attribute combinations impact the outcome-driven design of service experience. Based on the findings, we present a modular service design framework and a service design method tha…

A Multi-Projector Calibration Method for Virtual Reality Simulators with Analytically Defined Screens

2017

The geometric calibration of projectors is a demanding task, particularly for the industry of virtual reality simulators. Different methods have been developed during the last decades to retrieve the intrinsic and extrinsic parameters of projectors, most of them being based on planar homographies and some requiring an extended calibration process. The aim of our research work is to design a fast and user-friendly method to provide multi-projector calibration on analytically defined screens, where a sample is shown for a virtual reality Formula 1 simulator that has a cylindrical screen. The proposed method results from the combination of surveying, photogrammetry and image processing approac…

Computationally Efficient Innovative Techniques for the Design-Oriented Simulation of Free-Running and Driven Microwave Oscillators

2014

Analysis techniques for injection-locked oscillators/amplifiers (ILO) can be broadly divided into two classes. To the first class belong methods with a strong and rigorous theoretical basis, that can be applied to rather general circuits/systems but which are very cumbersome and/or time-consuming to apply. To the second class belong methods which are very simple and fast to apply, but either lack of validity/accuracy or are applicable only to very simple or particular cases. In this thesis, a novel method is proposed which aims at combining the rigorousness and broad applicability characterizing the first class of analysis techniques above cited with the simplicity and computational efficie…

Space-by-Time Modular Decomposition Effectively Describes Whole-Body Muscle Activity During Upright Reaching in Various Directions

2017

The modular control hypothesis suggests that motor commands are built from precoded modules whose specific combined recruitment can allow the performance of virtually any motor task. Despite considerable experimental support, this hypothesis remains tentative as classical findings of reduced dimensionality in muscle activity may also result from other constraints (biomechanical couplings, data averaging or low dimensionality of motor tasks). Here we assessed the effectiveness of modularity in describing muscle activity in a comprehensive experiment comprising 72 distinct point-to-point whole-body movements during which the activity of 30 muscles was recorded. To identify invariant modules o…

Developments in the biomechanics and equipment of Olympic cross-country skiers

2018

Source at: http://doi.org/10.3389/fphys.2018.00976 Here, our aim was to describe the major changes in cross-country (XC) skiing in recent decades, as well as potential future developments. XC skiing has been an Olympic event since the very first Winter Games in Chamonix, France, in 1924. Over the past decades, considerable developments in skiing techniques and improvements in equipment and track preparation have increased skiing speed. In contrast to the numerous investigations on the physiological determinants of successful performance, key biomechanical factors have been less explored. Today’s XC skier must master a wide range of speeds, terrains, and race distances and formats (e.g., dis…

Architettura e natura nei centri minori in Sicilia. Esperienze temporanee di progetto: la cascata di San Nicola nella valle di Bolognetta

2021

The current Covid-19 emergency has revealed the crucial role of the health issue, not only in terms of healthcare facilities, but also in new ways to get better, spend more free time outdoors, eat healthy and revive the economies of Local communities. Action research takes on a leading role of the Recovery Fund, of the Green New Deal in order to identify better opportunities and strategies, increasing administrative capacities and skills in small towns, through a better use of available European, national and regional funds aimed at regenerate places that until yesterday were considered on the margins. The small towns must have territorial projects capable of combining development and susta…

Commentary: Long-term Practice with Domain-Specific Task Constraints Influences Perceptual Skills.

Right to the Future

2017

During the last decade, the city of Palermo has been undergoing relevant transformations from various perspectives. This has been the consequences of a multitude of circumstances, European financial crisis, migrants/refugees crisis, a new administration of the city and an increased awareness and responsibility among the citizens. Various national and international recognitions (Italian Cultural Capital 2018, the European Biennial of Contemporary Art, Manifesta 12, Youth Capital 2017) have confirmed that they are on the right path. This positive moment has been launched and, progressively, rid- den by many young professionals that decided to challenge the present situation by investing their…
