More Than (Single) Text Comprehension? – On University Students’ Understanding of Multiple Documents
2020
The digital revolution has made a multitude of text documents from highly diverse perspectives on almost any topic easily available. Accordingly, the ability to integrate and evaluate information from different sources, known as multiple document comprehension, has become increasingly important. Because multiple document comprehension requires the integration of content and source information across texts, it is assumed to exceed the demands of single text comprehension due to the inclusion of two additional mental representations: the integrated situation model and the intertext model. To date, there is little empirical evidence on commonalities and differences between single text and mult…
Force Concept Inventory-based multiple-choice test for investigating students’ representational consistency
2010
This study investigates students' ability to interpret multiple representations consistently (i.e., representational consistency) in the context of the force concept. For this purpose we developed the Representational Variant of the Force Concept Inventory (R-FCI), which makes use of nine items from the 1995 version of the Force Concept Inventory (FCI). These original FCI items were redesigned using various representations (such as motion map, vectorial and graphical), yielding 27 multiple-choice items concerning four central concepts underpinning the force concept: Newton's first, second, and third laws, and gravitation. We provide some evidence for the validity and reliability of the R-FC…
Multi-criteria risk classification to enhance complex supply networks performance
2021
[EN] Management of complex supply networks is a fundamental business topic today. Especially in the presence of many and diverse stakeholders, identifying and assessing those risks having a potential negative impact on the performance of supply processes is of utmost importance and, as a result, implementing focused risk management actions is a current lively field of research. The possibility of supporting Supply Chain Risks Management (SCRM) is herein explored from a Multi-Criteria Decision-Making (MCDM)-based perspective. The sorting method ELimination Et Choix Traduisant la REalite (ELECTRE) TRI is proposed as a structural procedure to classify Supply Chain Risks (SCRs) into proper risk…
On the Neron-Severi group of surfaces with many lines
2008
For a binary quartic form $\phi$ without multiple factors, we classify the quartic K3 surfaces $\phi(x,y)=\phi(z,t)$ whose Neron-Severi group is (rationally) generated by lines. For generic binary forms $\phi$, $\psi$ of prime degree without multiple factors, we prove that the Neron-Severi group of the surface $\phi(x,y)=\psi(z,t)$ is rationally generated by lines.
Intrahepatic cholangiocarcinoma: Limitations for resectability, current surgical concepts and future perspectives.
2020
Intrahepatic cholangiocarcinoma (iCCA) is the second most common hepatic malignancy and its incidence has been shown to increase significantly during the past decades. Complete surgical resection is currently acknowledged as the only curative treatment option able to provide adequate long-term outcomes. We herein review technical, functional and oncologic limitations for resectability, discuss current surgical aspects as well as highlight the fields in which future research and practice should focus on in order to ameliorate long-term outcomes in patients with iCCA.
Sustainable Renovation Framework: Introducing three levels of Integrated Design Process Implementation and Evaluation
2017
Future sustainable building renovation is a balance between the economic and environmental impacts related to the desired social activities facilitated by the renovated building. A review of recent research has revealed that the present efforts on sustainable objectives fulfilment in renovation projects are not sufficient. This paper investigates processes and frameworks in building renovation. It aims to deal with simplification of the existing complexity due to involvement of various types of stakeholders, sustainability criteria and potential renovation technologies in design process. Moreover, it facilitates understanding of the design process implementation through identification of th…
'Participative foresight scenario mapping': adapting an MCM method to appraise foresight scenarios for the long term sustainable development of a sma…
2016
Multi-criteria mapping (MCM) appraisal has been used in projects involving decisions related to specific technologies or policies in risk analysis. In this research, MCM has been adapted for appraising in a participative way holistic scenarios for a small isolated island. The procedural novelty relies on how the scenario building and the criteria selection were undertaken. Two scenarios for Flores Island (Portugal) were developed in a two step process involving, firstly, specialised stakeholders and decision-makers, and secondly, lay citizens. The scenarios aimed at proposing alternative visions of future. This article analyses the methodological aspects of the project (scenario development…
An ex post criticism, based on stakeholders’ preferences, of a residential sector’s energy master plan: the case study of the Sicilian region
2016
Energy master plans are important tools for an effective and sustainable land governance. On the other hand, the stakeholder role in setting priorities for planning energy interventions is dramatically increasing, also in the light of recently issued European directives. The priorities of energy-saving measures of the Sicilian energy and environmental master plan were originally established with the application of typical economic indicators (the cost of saved energy and the cost of avoided pollutant emissions). During the prioritization process, there was a minor contribution from stakeholders who were not directly involved in the priority-setting process but were only asked to express the…
Health system reforms and the needs of the ageing population : an analysis of recent policy paths and reform trends in Finland and Sweden
2022
AbstractPopulation ageing with an increasing number of people experiencing complex health and social care needs challenges health systems. We explore whether andhow health system reforms and policy measures adopted during the past two decades in Finland and Sweden reflect and address the needs of the older people. We discuss health system characteristics that are important to meet the care needs of older people and analyse how health policy agendas have highlighted these aspects in Finland and Sweden. The analysis is based on “most similar cases”. The two countries have rather similar health systems and are facing similar challenges. However, the policy paths to address these challenges are…
Process and technology challenges in swift-starting virtual teams
2007
Originally published in the journal Information & Management : http://www.sciencedirect.com/science/journal/03787206 Virtual teams often face tight schedules and a need to start quickly and perform instantly. The goal of our study was to enhance understanding of the challenges faced by such teams. We used time–interaction–performance theory as the framework for following the processes and functions within virtual teams working on a systems development task. Our study provided a detailed examination of the group process, applied to virtual teams working under time pressure. The challenges faced by virtual teams in such settings showed that teams must work to enhance their effectiveness in mu…
