Conceptual Understanding of Newtonian Mechanics Through Cluster Analysis of FCI Student Answers

2018

The Force Concept Inventory is a multiple-choice test and is one of the most popular and most analyzed concept inventories. It is used to investigate student understanding of Newtonian mechanics. A structured approach to data analysis can transform it in a “diagnostic” instrument that can validate inferences about student thinking. In this paper, we show how cluster analysis methods can be used to investigate patterns of student conceptual understanding and supply useful details about the relationships among student concepts and misconceptions. The answers given to the FCI questionnaire by a sample of freshman engineering have been analyzed. The analysis takes into account the decomposition…

Energy and CO2 life cycle inventory issues for aluminum based components: The case study of a high speed train window panel

2016

Abstract As materials production and transport are two relevant sectors in terms of global environmental impact, over the last years environmental impact analyses (mainly life cycle based analyses) of material replacing strategies in means of transportation were developed. Life cycle approach allows to consider the light-weighing benefit without neglecting the environmental impact of material production. In the present research energy and CO2 emissions life cycle analysis of a real case study is presented. Industrial data, experimental measurements and literature analysis were used to develop the life cycle analysis of an aluminum window panel to be assembled on an Italian high speed train.…

Comparing soil inventory with modelling: Carbon balance in central European forest soils varies among forest types

2018

Abstract Forest soils represent a large carbon pool and already small changes in this pool may have an important effect on the global carbon cycle. To predict the future development of the soil organic carbon (SOC) pool, well-validated models are needed. We applied the litter and soil carbon model Yasso15 to 1838 plots of the German national forest soil inventory (NFSI) for the period between 1985 and 2014 to enables a direct comparison to the NFSI measurements. In addition, to provide data for the German Greenhouse Gas Inventory, we simulated the development of SOC with Yasso15 applying a climate projection based on the RCP8.5 scenario. The initial model-calculated SOC stocks were adjusted…

Application of the IO Methodology to the Energy and Environmental Analysis of a Regional Context

2009

Performing an energy and environmental analysis, researchers have to face many problems regarding the data quality and availability. Data are often out-of-date, not representative and consistent or, frequently, referred to faraway geographic and productive contexts. The Input-Output (IO) model, due to its simplicity, allows to acquire information regarding the energy and environmental performances of productive sectors.

Potere, consenso e dissenso nell’Ystoriola Langobardorum Beneventum degentium di Erchemperto

2021

Diversamente da quella narrata da Paolo Diacono nella «Historia Langobardorum», la storia dei Longobardi di Benevento fra l’VIII e il IX secolo, raccontata da Erchemperto nell’«Ystoriola Langobardorum Beneventum degentium», è una storia nella quale si alternano continuamente il bene e il male, Dio e Satana, il coraggio, la virtù, l’abnegazione da un lato e, dall’altro, la viltà, il tradimento, la perfidia. Personaggi positivi e personaggi negativi – insieme alle vicende delle quali, di volta in volta, essi sono protagonisti – si susseguono nell’«Ystoriola» a ritmo incalzante, e lo storico beneventano, talora in modo palese e scoperto, più spesso in maniera ellittica e sottintesa, manifesta …

Percepción de los residentes sobre los impactos de un gran evento deportivo: Desarrollo y validación de una escala

2017

Esta tesis doctoral desarrolla y valida una escala para analizar el impacto social de los eventos deportivos en la población española. Asimismo, se analiza el impacto social de un gran evento deportivo como es el Gran Premio de Europa de Fórmula 1 celebrado entre los años 2008 y 2012 en la ciudad de Valencia. Por lo tanto, este estudio tiene tres objetivos generales: en primer lugar, desarrollar y validar una escala para analizar la percepción de los residentes sobre los impactos asociados a la celebración de un gran evento deportivo; segundo, comprobar la validez de la escala para conocer las percepciones de los residentes sobre el Gran Premio de Europa de Fórmula 1; y, tercero, conocer la…

Revisión de las admisiones en Urgencias como elemento evaluador de la Calidad Asistencial. Impacto de los eventos adversos en el Servicio de Urgencia…

2015

La importancia creciente de suministrar una atención sanitaria de calidad, junto a la necesidad de conocer las condiciones en las que se producen los errores hacen que las investigaciones sobre Eventos Adversos (EAs) sean cada vez más frecuentes en las últimas décadas.El conocimiento de la situación en relación a la no Seguridad en la que se encuentra nuestro hospital y los costes derivados de ella nos permitirá avanzar en el ciclo de mejora continua de la calidad, aplicando nuevas medidas que puedan hacer de nuestro hospital un centro más seguro para el paciente y a su vez mejorar la eficiencia del sistema.Objetivo: Evaluar el impacto asistencial y económico de los EAs en el Servicio de Ur…

Il territorio dell'acqua: Saragozza dopo l'Expo 2008

2013

Several European cities have based their development and their international promotion on culture as an instrument for urban renewal. In Spain the experience of Zaragoza is polymorphic and projects itself into the future thanks to the different proposals, which it aims to realise, as well as to the scale of the projects in the territory. After the Expo 2008, Zaragoza distinguished itself by its dynamic activity in the recent candidatures aimed to organise new international events. Indeed the city through the events aspires to reinforce its role as a event city at national and international level. It undertakes to complete the diverse projects included in the Strategic Plan, which supported …

L'America's Cup 2007 e l'estensione del porto

2008

La città europea rappresenta oggi uno straordinario luogo di innovazione del rapporto fra progetto e fatti urbani. Negli ultimi anni molte grandi città o nuclei minori di interesse storico hanno avviato progetti di rigenerazione attraverso interventi di trasformazione del tessuto urbano e dello spazio pubblico che riguardano in particolare la trasformazione del waterfront, la riqualificazione del patrimonio architettonico e la costruzione di edifici esemplari. L’argomento di questo testo, che si inserisce nell’ambito delle ricerche da me condotte sulla cultura della trasformazione della città1, intende indagare il contributo dei grandi eventi come fattore di trasformazione sostenibile dei c…
