Informazione biomedica su Internet e motori di ricerca. Risultati di un trial di un anno
2004
The internet is a communication medium and content distributor that provide information in the general sense but it could be of great utility regarding as the search and retrieval of biomedical information. Search engines represent a great deal to rapidly find information on the net. However, we do not know whether general search engines and meta-search ones are reliable in order to find useful and validated biomedical information. The aim of our study was to verify the reproducibility of a search by key-words (pediatric or evidence) using 9 international search engines and 1 meta-search engine at the baseline and after a one year period. We analysed the first 20 citations as output of each…
Economia della condivisione e antropologia dello scambio
2017
The article analyses the distinctive economic models based on sharing that proliferated with the rise of web 2.0 (or social web). In particular, it analyzes what sharing means in different contexts (material and immaterial goods, and services) and it questions whether sharing can be seen as a discrete category, different from both market exchange and gift. Finally, the article questions the role of law with respect of these new economic activities.
Toward a formal sociology of online harassment
2019
Online harassment and various subcategories of it, like doxing and swatting, have attracted enormous interest for several years now—and particular interest in the world of game studies in the wake of 2014’s GamerGate harassment campaign. Such protracted, crowdsourced campaigns remain undertheorized, however. Using contemporary research to modify Georg Simmel’s formal sociological method, I provide researchers and the wider public with an easily visualized structure that most harassment campaigns follow: the form of an inverted pyramid bearing down on an individual target, stratified into three orders of harassment, each defined by level of severity and invasiveness. With this form, the publ…
Las imbricaciones políticas entre la participación ciudadana e internet
2019
In this article the author tries to show the direct relationships that are established between the possibilities offered by the Internet and a participatory improvement. Citizen participation is a basic element in anydemocratic construction, so using the tools available with the growth of the Internet is a crucial issue for democratic progress. Obviously the relationship with social networks is also widely discussed and studied, reflecting on whether the political advances involved are sufficient for better collective coexistence or if, on the contrary, it is a projection of apparent progress. Finally, the issue related to electronic voting is analyzed as a paradigm of online participatory …
Internet addiction in nursing students
2019
BACKGROUND: Problematic internet use is a growing problem in modern societies. Internet addiction (IA ) can be defined as a behavioral addiction between human and information technology-machine. Our aim was to identify IA among Palermo University nursing students by means of the Internet Addiction Test. METHODS: The study employed a cross-sectional study design. In April 2019 a survey was provided to students who attend daily lessons. The questionnaire was structured into two parts. The first section investigates on socio-demographic information, year of study, the perception of the economic and health status. In the second section of the questionnaire IAT was administered. A multivariable …
Modos de enseñanza en los videotutoriales de matemáticas: equilibrio entre eficacia puntual y utilidad formativa
2020
Resumo Presentamos una propuesta de análisis de videotutoriales de internet basado en los estilos cognitivos Holístico-analítico y Verbal-imaginativo. Para ello, se distinguen entre dos modos de enseñanza: la eficacia puntual (resolver un problema aquí y ahora) y la utilidad formativa (resolver un problema ahora y para problemáticas afines). La utilidad docente de un videotutorial puede depender de un equilibrio adecuado entre estos modos de enseñanza. Se trata de lograr resolver un problema ahora, pero con sustentos generales y a más largo plazo. La caracterización de los videotutoriales, en este sentido, podría ayudar a los profesores en la elección de videos, ya que según sus necesidades…
Les pays en développement à l'ère de l'e-learning
2012
En ligne sur : http://www.iiep.unesco.org/fileadmin/user_upload/Info_Services_Publications/pdf/2012/Fund96_FR.pdf; Si la formation à distance (FAD) réduit l'éloignement géographique, elle permet aussi de contrôler la distance sociale ou économique, grâce à une structure de coûts plus favorable. Est-ce une aubaine pour les pays en développement (PED) ? L'avènement des technologies numériques, tout en rapprochant les populations éloignées, permet le développement de modèles pédagogiques adaptés et diversifiés, avec une approche économique qui ne vise plus seulement les économies d'échelle. Dans cet ouvrage, Christian Depover et François Orivel tentent de déterminer quels bénéfices les PED, et…
Redes de innovación cívica e inteligencia colectiva
2016
El ciberespacio debería servir para conectar a la gente y colaborar más allá de barreras lingüísticas, nacionales o culturales. Esto ha sido denominado «cosmopolitismo digital». El propósito de este trabajo es explorar el potencial de las redes sociales para impulsar el voluntariado, el compromiso cívico y revitalizar el proceso democrático. Para ello se caracterizará el concepto de «cosmopolitismo digital» y los retos a los que se enfrenta, mostrando en qué medida Internet ha contribuido a crear un espacio donde es posible una construcción colectiva del conocimiento, potenciado por el movimiento del software libre y orientado a crear una cultura de la generosidad. La tecnología puede favor…
Community-driven computational biology with Debian Linux
2011
Background The Open Source movement and its technologies are popular in the bioinformatics community because they provide freely available tools and resources for research. In order to feed the steady demand for updates on software and associated data, a service infrastructure is required for sharing and providing these tools to heterogeneous computing environments. Results The Debian Med initiative provides ready and coherent software packages for medical informatics and bioinformatics. These packages can be used together in Taverna workflows via the UseCase plugin to manage execution on local or remote machines. If such packages are available in cloud computing environments, the underlyin…
Internet-based perioperative exercise program in patients with Barrett’s carcinoma scheduled for esophagectomy [iPEP - study] a prospective randomize…
2017
Abstract Background Patients undergoing surgery for esophageal cancer have a high risk for postoperative deterioration of lung function and pulmonary complications. This is partly due to one-lung ventilation during thoracotomy. This often accounts for prolonged stay on intensive care units, delayed postoperative reconvalescence and reduced quality of life. Socioeconomic disadvantages can result from these problems. Physical preconditioning has become a crucial leverage to optimize fitness and lung function in patients scheduled for esophagectomy, in particular during the time period of neoadjuvant therapy. Methods/Study design We designed a prospective multicenter randomized-controlled tria…
