MAD+. Introducing Misconceptions in the Temporal Analysis of the Mathematical Modelling Process of a Fermi Problem
2021
This work describes how the combination of the mistakes committed by a group of pre-service teachers when solving a Fermi problem, with the representation of the temporal analysis of their resolutions, can offer more in-depth information about their conceptual misconceptions regarding mathematical and modelling concepts. The combined representation allows knowing when mistakes occur and provides a powerful tool for instructors to adapt the teaching–learning processes of mathematics at all levels of education. Our study is based on a recent categorisation of students’ mistakes, together with the creation of a new representation tool, called MAD+, that can combine all this information. The ma…

A generalized transitive closure for relational queries
1988
We augment relational algebra with a generalized transitive closure operator that allows for the efficient evaluation of a subclass of recursive queries. The operator is based on a composition operator which is as general as possible when the operator is required to be associative and when only relational algebra operators are used in its definition. The closure of such a composition can be computed using the well-known efficient algorithms designed for the computation of the usual transitive closure. Besides the case in which complete materialization of recursive relations are required, our strategy also yields an efficient solution in the case in which a selection is applied to the closur…
La Convención de Palermo (UNTOC) y la responsabilidad derivada de delitos de las personas jurídicas: itinerarios e intersecciones del ordenamiento it…
2022
Both the United Nations Convention against Transnational Organised Crime (UNTOC: signed in December 2000 in Palermo) and the Delegation Law no. 300/2000, with its corresponding Legislative Decree no. 231/2001, which jointly introduced in Italy the liability arising from crime for collective entities, mark two "paradigm shifts" for the criminal system. The contribution focuses on the overall value of the two legislative innovations examined in the evolution of criminal law, respectively at the international level and in the Italian context. The interest in analysing their respective contributions is further stimulated by the observation that the two areas, although autonomous, present a sign…
Differences in treatment adherence, program completion, and recidivism among batterer subtypes
2017
Abstract The present study aimed to cross-validate Holtzworth-Munroe and Stuart's typology in a Spanish sample of court-referred intimate partner violence batterers. The study also analyzed the typology's capability to predict treatment attendance, completion, and IPV recidivism two years after the treatment. The sample consisted of 210 batterers court referred to a batterer intervention program. Using cluster analysis, three batterer subtypes were identified in accordance with the original typology: family-only batterers, borderline/dysphoric, and generally violent-antisocial. The typology predicted program attendance, completion, and recidivism. Batterers from the generally violent-antiso…
Norskfaget i endring : en sammenlikning av L97 og kunnskapsløftet
2006
Masteroppgave i Nordisk språk og litteratur 2006 - Høgskolen i Agder, Kristiansand Oppgaven er bygd opp slik at jeg først gir en kort innføring i L97 og Kunnskapsløftet i innledningskapitlet, og etter det følger det et kapittel om teori og metode. Siden det er vanskelig å skille disse to, velger jeg å skrive om dem sammen. Etter dette kommer et kapittel om læreplaner i historisk perspektiv. Dette har jeg skrevet for å avdekke hvor Kunnskapsløftet plasserer seg i en eksisterende læreplantradisjon. Gjennom det kan jeg undersøke hvor det er mulig å trekke paralleller mellom L97, Kunnskapsløftet og tidligere læreplaner. Pendelen svinger fra epoke til epoke, og muligheten er der jo for at ting f…
Apvienotā Eiropas Tora vakuumkameras volframa materiālu oksidēšanās dažādās vidēs
2020
Bakalaura darbā apkopota informācija par termisko kodolsintēzi, tokamakiem un to potenciālajiem negadījumiem – dzesēšanas un vakuuma zudumu –, divertora materiālu – volframu –, tā oksīdiem un oksidēšanās procesiem atkarībā no temperatūras, kā arī volframa un tā oksīdu reakcijām ar ūdeni. Volframa oksidēšanās procesu izpētei izmantota pulvera rentgendifraktometrijas, termiskās analīzes un elektronu mikroskopijas metode, lai raksturotu volframa struktūru, virsmas morfoloģiju un novērtētu mitruma ietekmi uz volframa oksidēšanos. Eksperimentālajā daļā veikta volframa paraugu karsēšana no istabas temperatūras līdz 1000°C sausā un mitrā sintētiskā gaisa plūsmā. Ar termogravimetrijas metodi noteik…
How should vaccination services be planned, organized, and managed? Results from a survey on the Italian vaccination services
2019
Background. Quality improvement is an increasingly recognized approach to maximize service effectiveness and minimize costs in public health. However, the Italian law never provided for the institutional accreditation of vaccination services. Furthermore, a recently approved law added six more compulsory vaccinations to the original four, which has led to a considerable increase in vaccination efforts, without any previous resources evaluation. The aim of the study was to investigate structural, organizational and managerial characteristics of the Italian vaccination services, in order to suggest the adoption of adequate quality standards. Study design. A survey involving the representative…
Perceptual Processing and the Comprehension of Relational Information in Dynamic Diagrams
2018
International audience; To date, research on the processing involved in comprehending and learning from animated diagrams has accorded a minor role only to perceptual operations in general and peripheral processing in particular. For those aspects where the role of perception is acknowledged, it is foveal rather than peripheral processing that is regarded as the main player. In this paper, we use the results from additional finer grained analysis of data collected in a recent empirical study to suggest that information from a viewer’s peripheral field can play a much more central role in animation processing than has previously been recognized. It appears that if the dynamic information com…
Anomaly Detection from Network Logs Using Diffusion Maps
2011
The goal of this study is to detect anomalous queries from network logs using a dimensionality reduction framework. The fequencies of 2-grams in queries are extracted to a feature matrix. Dimensionality reduction is done by applying diffusion maps. The method is adaptive and thus does not need training before analysis. We tested the method with data that includes normal and intrusive traffic to a web server. This approach finds all intrusions in the dataset. peerReviewed
