Managing an Online Survey about Influenza Vaccination in Primary Healthcare Workers
2015
Online surveys are increasingly used due to their speed and efficiency. The aim of this study was to analyze factors that may have contributed to the quality and speed of response of an online survey on influenza vaccination in primary healthcare workers. A multicenter study including family physicians, nurses and pediatricians from primary healthcare teams from seven Spanish Autonomous Communities was designed. The centers were selected by simple random sampling. The survey remained active and accessible for 56 days and four reminders were sent. The odds ratios (OR) and their 95% confidence intervals (CI) were calculated to assess the association of sociodemographic variables and respondin…
Robust delay-dependent H∞ control of uncertain time-delay systems with mixed neutral, discrete, and distributed time-delays and Markovian switching p…
2011
Author's version of an article published in the journal: IEEE Transactions on Circuits and Systems I: Regular Papers. Also available from the publisher at: http://dx.doi.org/10.1109/tcsi.2011.2106090 The problem of robust mode-dependent delayed state feedback H ∞ control is investigated for a class of uncertain time-delay systems with Markovian switching parameters and mixed discrete, neutral, and distributed delays. Based on the LyapunovKrasovskii functional theory, new required sufficient conditions are established in terms of delay-dependent linear matrix inequalities for the stochastic stability and stabilization of the considered system using some free matrices. The desired control is …
Human Activity Signatures Captured under Different Directions Using SISO and MIMO Radar Systems
2022
In this paper, we highlight and resolve the shortcomings of single-input single-output (SISO) millimeter wave (mm-Wave) radar systems for human activity recognition (HAR). A 2×2 distributed multiple-input multiple-output (MIMO) radar framework is presented to capture human activity signatures under realistic conditions in indoor environments. We propose to distribute the two pairs of collocated transmitter–receiver antennas in order to illuminate the indoor environment from different perspectives. For the proposed MIMO system, we measure the time-variant (TV) radial velocity distribution and TV mean radial velocity to observe the signatures of human activities. We deploy the Anc…
Valutazione formativa e didattica a distanza all’Università
2021
La valutazione per l’apprendimento (assessment for learning) e la valutazione come apprendimento (assessment as learning) sono concetti che recentemente hanno assunto un ruolo centrale nella letteratura sull’argomento. Il contributo illustra, dopo una esplicitazione delle caratteristiche dei due approcci, un’esperienza di valutazione per l’apprendimento e come apprendimento in Università. La ricerca si propone di descrivere come 125 studenti del corso di Laurea Magistrale di Scienze della Formazione Primaria dell’Università di Palermo partecipino abitualmente al processo di valutazione e percepiscano l’utilità della valutazione formativa e i benefici del ricevere feedback. I dati raccolti …
Narrazioni al femminile di Cosa Nostra
2010
Starting from the analysis of the important transformations that have characterized the roles of women within the criminal world of Cosa Nostra in the last decades, the article focuses on the dimensions of identity and communication through which the belonging of women to the mafia universe or their exclusion from male territories are defined. In the last two decades, the criminal organization, weakened by the many arrests, has increasingly entrusted to women the responsibility to preserve, affirm and reflect its image of power to the outside. In times of emergency, women are considered the most reliable interlocutors. Using direct evidence, interviews, letters and judicial materials, the a…
Geomatic applications tourban park in palermo
2015
Over the last few years topographical techniques have developed an exponential trend towards simplifying and speeding, both survey operations and analysis of data collected reaching at the same time ever higher levels of accuracy. Among the technologies that are increasingly taking the field in this context is part of the Mobile Mapping System (MMS) that, on any mobile platform, combines sensors and measurement systems designed to provide a 3D position of the platform and, at the same time, capable to acquire geographic data without the aid of control points on the ground. The study reported concerns the verification of the reliability metrics and a qualitative MMS in order to evaluate its …
Dysfunction of the mesolimbic circuit to food odors in women with anorexia and bulimia nervosa: A fMRI study
2019
Brain reward dysfunction in eating disorders has been widely reported. However, whether the neural correlates of hedonic and motivational experiences related to food cues are differentially affected in anorexia nervosa of restrictive type (ANr), bulimia nervosa (BN), and healthy control (HC) participants remains unknown. Here, 39 women (14 ANr, 13 BN, and 12 HC) underwent fMRI while smelling food or non-food odors in hunger and satiety states during liking and wanting tasks. ANr and BN patients reported less desire to eat odor-cued food and odor-cued high energy-density food (EDF), respectively. ANr patients exhibited lower ventral tegmental area (VTA) activation than BN patients to food od…
Ecomusei e micromusei
2022
Faced with a renewed framework of museology, the concept of cultural heritage, expanding enormously, refers to a great complexity of underlying elements, stories and relationships that require and await a necessary narrative, conveyed by material and immaterial, communicative artifacts. Design is called, today more and more often, to operate within the complexity of design strategies that are able to develop new ways of enhancing, communicating and using cultural heritage and traditional productions rooted in the territories, exploring their multiple aspects also through methodologies of highly experimental design (interactive, multimedia). Each ecomuseum represents a unique reality, by ter…
Developmental Dynamics of Math Performance From Preschool to Grade 2.
2004
This study investigated the developmental dynamics of mathematical performance during children's transition from preschool to Grade 2 and the cognitive antecedents of this development. 194 Finnish children were examined 6 times according to their math performance, twice during each year across a 3-year period. Cognitive antecedents, that is, counting ability, visual attention, metacognitive knowledge, and listening comprehension, were tested at the first measurement point. The results indicated that math performance showed high stability and increasing variance over time. Moreover, the growth of math competence was faster among those who entered preschool with an already high level of mathe…
