Seismically-induced soft-sediment deformation structures in Upper Triassic deepwater carbonates (Central Sicily)
2016
We describe soft-sediment deformation structures into the Upper Triassic cherty limestone outcropping in the Pizzo Lupo section (Central Sicily, Italy), pertaining to the deep-water palaeodomain of the Southern Tethyan margin. In the study section, mainly consisting of thin-bedded mudstone/marl alternations with bedded chert intercalations, some lithofacies have been separated on the basis of the abundance of the calcium carbonate/clay content and the overall textural features. The deformational structures, displaying different deformational styles as folded and faulted beds, disturbed layers, clastic dikes, and slumps occur mainly in the deformed horizons that involve marl-dominated lithof…
Learning Path Generation by Domain Ontology Transformation
2005
An approach to automated learning path generation inside a domain ontology supporting a web tutoring system is presented. Even if a terminological ontology definition is needed in real systems to enable reasoning and/or planning techniques, and to take into account the modern learning theories, the task to apply a planner to such an ontology is very hard because the definition of actions along with their preconditions and effects has to take into account the semantics of the relations among concepts, and it results in building an ontology of learning. The proposed methodology is inspired to the Knowledge Space Theory, and proposes some heuristics to transform the original ontology in a weig…

Iterated Conditionals, Trivalent Logics, and Conditional Random Quantities
2022
We consider some notions of iterated conditionals by checking the validity of some desirable basic logical and probabilistic properties, which are valid for simple conditionals. We consider de Finetti’s notion of conditional as a three-valued object and as a conditional random quantity in the betting framework. We recall the notions of conjunction and disjunction among conditionals in selected trivalent logics. Then, we analyze the two notions of iterated conditional introduced by Calabrese and de Finetti, respectively. We show that the compound probability theorem and other basic properties are not preserved by these objects, by also computing some probability propagation rules. Then, for …

ANATOMICAL DISSECTION AND ANALYSIS OF THE STRUCTURES OF THE UPPER LIMB
2017
In 2015, a whole body dissection course was proposed by the University of Palermo, Palermo, Italy, thanks to the cooperation with the University of Malta, Msida, Malta. The purpose of this study was to show the the difference between the studyof anatomy on books and on corpses. The article focuses its attention on the dissection method of the upper limb. The astudy was performed on two corpses, a male and a female, by using a basic surgeon kit. Blunt dissection method was used for fasciae, innards and to isolate vascular-nervous structures from the fat; we used scalped for cutis, sub cutis, muscles, fasciae, veins, arteries and nerves of the upper limb from the shoulder to the hand. The upp…

Why Study Online in Upper Secondary School? Qualitative Analysis of Online Learning Experiences
2015
In Finland, online learning has become more common in recent years. In this study, we examined why adult students chose to study online for upper secondary school. The research also focused on the support needed for learning from a special education perspective. Both qualitative and quantitative data were collected using an electronic questionnaire. In total, 58 students responded. Data were analyzed qualitatively using the content analysis technique. The findings indicate that the main reasons for online studies are similar in Finland to those found internationally: flexibility of timetables, the student’s health condition, and family situations. The findings also indicate that a student’s…
Changes in achievement values from primary to lower secondary school among students with and without externalizing problems
2017
This study examined the effect of students' externalizing problems on changes in values that they attach to math across the transition from primary to lower secondary school. Data pertaining to externalizing problems and to intrinsic, attainment, and utility values in math were gathered using the self-ratings of students in Grades 6 and 7. The analysis involved a comparison between students who reported persistent high externalizing problems before and after the transition (n = 63; 59% boys) and those who had low or non-existent externalizing problems before and after the transition (n = 1352; 50% boys). The results of a mixed-design analysis of covariance (ANCOVA) showed uniformly that stu…
