Visioni parallele

2020

Saggio di presentazione dei lavori del workshop svoltosi nell’ambito del Seminario “Architettura costruita e spazio abitato nelle città di nuova fondazione in Italia e Spagna”, organizzato dal Dottorato di ricerca in Architettura Arti Pianificazione con l’Universidad de Exstremadura. Il testo presenta delle coppie dialettiche formate da realtà urbane italiane (individuate tra le città fondate nella Bonifica dell’Agro Pontino) e una spagnola (scelta tra le città della Colonizzazione dell’Estremadura) al fine di una lettura parallela.

Integrability of the one dimensional Schrödinger equation

2018

We present a definition of integrability for the one dimensional Schroedinger equation, which encompasses all known integrable systems, i.e. systems for which the spectrum can be explicitly computed. For this, we introduce the class of rigid functions, built as Liouvillian functions, but containing all solutions of rigid differential operators in the sense of Katz, and a notion of natural boundary conditions. We then make a complete classification of rational integrable potentials. Many new integrable cases are found, some of them physically interesting.

A Multiplicity result for a class of strongly indefinite asymptotically linear second order systems

2010

We prove a multiplicity result for a class of strongly indefinite nonlinear second order asymptotically linear systems with Dirichlet boundary conditions. The key idea for the proof is to bring together the classical shooting method and the Maslov index of the linear Hamiltonian systems associated to the asymptotic limits of the given nonlinearity.

Validating the early childhood classroom observation measure in first and third grade classrooms

2016

The present study reports on the psychometric properties of the Early Childhood Classroom Observation Measure (ECCOM) in Finnish and Estonian first and third grade classrooms. The observation data were collected from 91 first grade teachers and 70 third grade teachers. Teachers' curriculum goals, teaching experience and the classroom size were measured also. The results of confirmatory factor analysis provided evidence of the three-factor model (management, climate, and instruction) for each dimension—child-centred, teacher-directed, and child-dominated—in both grades. The reliability of the dimensions and sub-scales was good, and some evidence was also found for criterion validity. The fin…

A Study on Engineering Freshman Conceptual Understanding of Newtonian Mechanics

2021

Force concept inventory is a multiple-choice questionnaire commonly used to assess students’ conceptual understanding of Newtonian mechanics. We here show that a cluster analysis method can be used to study student answers to the force concept inventory to investigate their understanding of Newtonian mechanics and provide new insights into the use of the force concept inventory. We identi- fied groups of students characterized by similar correct answers as well as by non- correct answers to the questionnaire, whose analysis allowed us to highlight student misconceptions/non-normative conceptions. Such an analysis of student answers gave us insights into the relationships between the student…

Classroom management practices and their associations with children’s mathematics skills in two cultural groups

2014

The aim of the study was to examine the extent to which contextual factors predict children’s mathematics skills in different cognitive domains. The sample consisted of 1734 students from 26 Estonian- and 17 Russian-language schools in Estonia. Mathematics and non-verbal reasoning tests were carried out at the beginning of the third grade. In addition, teachers were asked about their classroom management practices. The results of multilevel modelling showed that applying supportive practices in the classroom contributes to higher achievement in mathematics. Teachers from Estonian- and Russian-language schools were also found to differ with regard to their management practices, and these pra…

Spazi aperti di comunità in ambito climatico Mediterraneo. Il caso di Hassan Fathy in Egitto

2022

The complexity of the relationship between architecture and the Mediterranean climate, in energy regimes and resource scarcity, requires special attention. Specifically, the article aims to explore how community spaces can become design subjects, intervening in climatic, environmental, social, and cultural features. Hassan Fathy’s architecture, in particular the two schools in New Gourna and Fares, offer a different key to understanding man, climate, culture, technology, and education. A relationship that is still evolving today, calling architecture back toits educational and social focus.

Almotriptan: meeting today’s needs in acute migraine treatment

2007

Migraine is a common disorder associated with considerable individual and economic burden. Triptans are recommended for the treatment of migraine of any severity in patients who have failed to gain adequate relief with nonspecific medication; early transition to triptans avoids prolonged morbidity in patients failing to respond to nonspecific medications. There is evidence that early intervention therapy with oral formulations in migraine, soon after the onset of an attack and when pain is still mild, improves efficacy. Seven different triptans are currently marketed, with differing pharmacologic, efficacy and tolerability profiles. Almotriptan has many positive features, which include rigo…

<title>Photonic vascular diagnostics by four-channel photoplethysmography</title>

2005

A four-channel photoplethysmography device was designed and built at University of Latvia to detect signals from different body parts and to analyze the signal shapes. The device consists of optical contact probes, interface, and a standard PC. Clinical tests were performed with occlusion patients having vascular problems at arm or leg arteries. Results showed significant difference in the pulse wave transit time in occluded and nonoccluded part of the body.© (2005) COPYRIGHT SPIE--The International Society for Optical Engineering.
