Collaborative writing with web 2.0 technologies: education students' perceptions
2011
Published version of an article from the journal: Journal of Information Technology Education. Also available from the publisher: http://jite.org/documents/Vol10/JITEv10IIPp073-103Brodahl948.pdf Executive Summary Web 2.0 technologies are becoming popular in teaching and learning environments. Among them several online collaborative writing tools, like wikis and blogs, have been integrated into educational settings. Research has been carried out on a wide range of subjects related to wikis, while other, comparable tools like Google Docs and EtherPad remain largely unexplored in the literature. This work presents a case study investigating education students' perceptions of collaborative writ…
A Low-Cost Multi-Modal Auditory-Visual-Tactile Framework for Remote Touch
2020
International audience; Haptic technology for human augmentation provides gains in ability for different applications, whether the aim is to enhance "disabilities" to "abilities", or "abilities" to "super-abilities". Commercially-available devices are generally expensive and tailored to specific applications and hardware. To give researchers a haptic feedback system that is economical, customisable, and fast to fabricate, our group developed a low-cost immersive haptic, audio, and visual experience built by using off-the-shelf (COTS) components. It is composed of a vibrotactile glove, a Leap Motion sensor, and an head-mounted display, integrated together to provide compelling immersive sens…
Trasferimenti tecnologici nella Sicilia d’età moderna: l'impiego del mattone a “cortina”
2016
In Sicilia, nel contesto di quella che è stata definita la civiltà della pietra, e tra i laboratori della stereotomia medioevale nel Mediterraneo, il ricorso al laterizio e alla tecnica costruttiva che l’impiego di un materiale “artificiale” comporta, ha generato in età moderna fabbriche che hanno operato uno scarto rispetto alla tradizione fino a produrre una nuova tradizione. La serie di casi che sono segnalati in questo contributo indicano come sia stata spesso la mobilità di alcuni maestri “forestieri” a spiegare l’introduzione, l’attecchimento e la fortuna dell’impiego del mattone a faccia vista, o altrimenti detto a “cortina”, nel cantiere siciliano d’età moderna. In Sicily, as a part…
The Patras blended strategy model for deep and meaningful learning in quality life-long distance education
2019
Life‑long learning is currently being embraced as a central process that could disrupt traditional educational paths. Apparently, the (ideal) type of learning often promoted is deep and meaningful learning, though it is not always required to be so. Deep learning goes beyond superficial knowledge assimilation of unlinked facts; it aims at developing deep disciplinary understanding, transformative knowledge, personal meaning, emotional intelligence, critical thinking, creativity and metacognitive skills. Meaningful learning occurs when learning is active, constructive, intentional, authentic, and cooperative. Technology enhanced teaching and learning methods should prove their potential to t…
Contrainte de crédit et convergence vers la frontière technologique: Qu'en est-il des pays de la Zone CFA ?
2014
EnglishThis work aims to study the effects of credit-market imperfection on the convergence of the cfa zone to the frontier growth rate. It focuses on the fact that a less efficient credit market is a constraint that prevents these countries to benefit from technology transfer and causes them to deviate from the frontier of growth. The empirical approach based on generalized method of moments (gmm) in dynamic panel shows that a low level of financial development significantly slow the rate of convergence of these countries. francaisCe travail a pour objectif d’etudier les effets de l’imperfection du marche du credit sur la convergence des pays de la communaute financiere africaine (cfa) ver…
Immunoanalytical approaches for the control of xenobiotics and biotoxins in food
2020
[ES] El control efectivo de la calidad y seguridad de los alimentos requiere de métodos analíticos que garanticen la determinación fiable de cualquier sustancia potencialmente perjudicial para el consumidor que pueda estar presente en el alimento antes de su distribución y comercialización. Una de las aproximaciones analíticas que contribuye a garantizar este objetivo engloba una serie de técnicas que tienen en común la utilización de anticuerpos como elementos esenciales para la detección del analito diana, y que en conjunto reciben el nombre de métodos inmunoquímicos. Este artículo pretender aportar una visión básica de los principios bioquímicos subyacentes a estas tecnologías y cuáles…
Infertility-related stress, anxiety and ovarian stimulation: can couples be reassured about the effects of psychological factors on biological respon…
2016
Abstract The aim of this prospective, longitudinal study was to examine the association between couples' pre-treatment psychological characteristics (state anxiety and infertility-related stress levels of both partners) and ovarian response during assisted reproductive technology treatment in a well-controlled sample. A total of 217 heterosexual couples (434 patients), suffering from primary infertility and undergoing their first assisted reproductive technology treatment at the Reproductive Medicine Unit of ANDROS Day Surgery Clinic in Palermo (Italy), were recruited. Psychological variables were assessed using the State Scale of State-Trait Anxiety Inventory (STAI-S) and the Fertility Pro…
Fractal-structured multifocal intraocular lens
2017
[EN] In this work, we present a new concept of IOL design inspired by the demonstrated properties of reduced chromatic aberration and extended depth of focus of Fractal zone plates. A detailed description of a proof of concept IOL is provided. The result was numerically characterized, and fabricated by lathe turning. The prototype was tested in vitro using dedicated optical system and software. The theoretical Point Spread Function along the optical axis, computed for several wavelengths, showed that for each wavelength, the IOL produces two main foci surrounded by numerous secondary foci that partially overlap each other for different wavelengths. The result is that both, the near focus an…
Technology and Labor Regulations: Theory and Evidence
2015
This paper shows that different labor market policies can lead to differences in technology across sectors in a model of labor saving technologies. Labor market regulations reduce the skill premium and as a result, if technologies are labor saving, countries with more stringent labor regulation, which bind more for low skilled workers, become less technolog- ically advanced in their high skill sectors, but more technologically advanced in their low skill sectors. We then present data on capital-output ratios, on estimated productivity levels and on patent creation, which tend to support the predictions of our model.
