Organizing for collaboration in simulation-based environments : an affordance perspective
2023
Extant research has identified the significance of technological affordances in computer-supported learning environments. However, until recently, there is scarcely empirical research on affordances for organizing collaboration in these learning environments. To address this gap, this study empirically examines affordances for organizing collaboration in a simulation-based learning environment. We focus, in particular on understanding how the organizing affordances of the learning environment are perceived and employed by the learners during a simulation-based learning task. The study was executed among 177 undergraduate higher education (HE) business students from 10 universities in Belgiu…
Misfit evaluation of dental implant-supported metal frameworks manufactured with different techniques: Photoelastic and strain gauge measurements
2016
This study aims to compare in-vitro the fitting accuracy of implant-supported metal frameworks used for full-arch orthodontic restoration. The hypotheses tested were as follows: (1) for a fixed implant morphology, strains developed within the framework depend on how the framework had been fabricated and (2) stresses transferred to the implant–bone interface are related to the amount of framework misfit. Metal frameworks were fabricated using four different manufacturing techniques: conventional lost-wax casting, resin cement luting, electrospark erosion, and computer-aided design/computer-aided manufacturing milling. Each framework was instrumented with three strain gauges to measure strai…
Ecology, fisheries and management of wild brown trout populations in boreal inland waters
2010
Eutrophication of aquatic ecosystems is an increasing problem, especially threatening small and shallow freshwater lakes. While the extreme inputs of nutrients (phosphorus and nitrogen) can nowadays be reduced and controlled rather efficiently, additional measures to reverse eutrophication may be needed. These often involve biomanipulation, typically mass removal of cyprinid fish. However, the success of biomanipulations has many times been limited or short lived. The reasons for this are not well known, perhaps because the more subtle impacts of biomanipulation on the ecosystem-wide processes of lakes have not been thoroughly studied. Natural abundance stable isotopes may provide a cost-ef…
Dipinto su tavola “Tre Sante Martiri”: il restauro conservativo di un supporto ligneo gravemente danneggiato
2020
Il poster descrive l'intervento conservativo svolto su un dipinto su tavola raffigurante “Tre Sante Martiri”, secondo il consolidato principio di un approccio multidisciplinare tecnico e scientifico. Il manufatto, realizzato con la tecnica ad olio e risalente al XVII secolo, è di proprietà del Comune di Cefalù (PA), pervenuto a seguito di lascito testamentario da parte di un nobile collezionista dell’Ottocento, l’avvocato Vincenzo Cirincione, ed è conservato presso il locale Museo intitolato ad “Enrico Piraino barone di Mandralisca”. La prima parte dell’intervento ha riguardato lo studio degli aspetti storico-artistici, dei materiali e delle tecniche esecutive, degli interventi pregressi di…
Perforación en bóveda palatina por consumo de cocaína
2006
El consumo de cocaína va en aumento en la población mundial, los efectos del consumo de esta droga pueden ocasionar efectos secundarios. Se presenta un caso de paciente femenino de 48 años de edad que presenta una úlcera crónica buco-nasal de 2 meses de evolución, la cual le ocasiona problemas para la deglución y fonación. Worldwide, the use of cocaine has an increased over the years, various secondary effects have been described. Here we present a 48 years old female with a 2-month evolution bucconasal ulcer in the hard palate induced by cocaine usage accompanied by swallow and phonation dysfunctions. Ethiopathogenesis, differential diagnoses and treatment are discussed.
eTwinning e Scuole Nuove: collaborazione e valorizzazione del patrimonio culturale
2022
All’inizio del Novecento, la diffusione in Europa di numerosi modelli di rinnovamento educativo in linea con il movimento delle Scuole Nuove e il conseguente approfondimento della documentazione prodotta in quegli anni, permettono di riflettere ancora oggi sull’argomento. Il presente contributo mira a verificare se la piattaforma eTwinning possa oggi essere considerata come una delle possibili vie per attuare quanto auspicato cento anni fa dal movimento delle Scuole Nuove: incoraggiare la collaborazione tra i membri della comunità scolastica al fine di comprendere il valore della diversità e del patrimonio culturale. At the beginning of the twentieth century, the spread of numerous educatio…
Global Trends in Scientific Research on Pediatric Obesity
2022
(1) Introduction: The aim of this study was to analyze scientific production, collaboration among countries, and research topics focusing on pediatric obesity. (2) Methods: The papers that were included in the study were retrieved from the Web of Science Core Collection from Clarivate Analytics. A bibliometric analysis of several focuses, including journals of publication, subject categories, most frequent author keywords, and journal impact factors, was conducted. Social network analysis was used to recognize collaboration groups between countries and the co-occurrences of author keywords. (3) Results: A total of 12,171 research articles were published in 2036 journals classified under a v…

Amuleto celtíbero con leyenda, un ejemplo inédito en la epigrafía ibérica
2014
Se presenta un ejemplo inédito de epigrafía ibéric a en una peculiar «chapa» lenticular de bronce. Descontextualizada arqueológicamente, la pieza presenta tres perforaciones, las cuales indicarían que se hicieron para portarla col gada o cosida a modo de amuleto. An unpublished sample of Iberian epigraphy on an o dd bronze, lenticular token is introduced. Found out of an archaeological context, this piece shows three holes which suggest that it was used as a hanging or sawed amulet
