The Role of Asymptomatic Individuals in the COVID-19 Pandemic <i>via</i> Complex Networks
2020
Background: Recent seroprevalence studies have tried to estimate the real number of asymptomatic cases affected by COVID-19. It is of paramount importance to understand the impact of these infections in order to prevent a second wave. This study aims to model the interactions in the population by means of a complex network and to shed some light on the effectiveness of localised control measures in Italy in relation to the school opening in mid-September.} Methods: The formulation of an epidemiological predictive model is given: the advantage of using this model lies in that it discriminates between asymptomatic and symptomatic cases of COVID-19 as the interactions with these two categorie…
Do Obese Children Achieve Maximal Heart Rate during Treadmill Running?
2019
Objective: Maximal heart rate (HR) is commonly defined as the highest HR obtained during a progressive exercise test to exhaustion. Maximal HR is considered one of the criteria to assess maximum exertion in exercise tests, and is broadly used when prescribing exercise intensity. The aim of the present study was to compare peak HR measurements during maximal treadmill running and active play in obese children and adolescents. Design: Comparison of peak heart rate during active play vs. maximal treadmill running in 39 (7&ndash
An Ion Exchange Membrane Crystallisation reactor for Magnesium recovery from brines
2015
CrIEM technology is a novel ion exchange application that allows reactive crystallization for separation of valuable species (e.g. Mg from brines) with a large flexibility in the choice of reactants.
Fuel cell analytical modeling: Solving the trade-off between accuracy and complexity
2013
In this paper, a 5.5 kW Proton Exchange Membrane fuel cell is modeled. The proposed analytical model is described and the parameters identification procedure is further discussed. Simulation results of all three sub-models are compared to test the accuracy of each one. A comparison between simulation and experimental results is provided as well validating the modeling approach.
Statistical Modelling and Risk Analysis of Bitcoins Exchange Rate
2018
Master's thesis Business Administration BE501 - University of Agder 2018 Bitcoin is a phenomenon that is new and there is little information on how and why it behaves as volatile as it does. This thesis uses existing data on Bitcoin’s exchange rate to estimate a model that describes the pattern and use it in a financial risk analysis. We also aim to contribute as a foundation for further studies in this field. The statistical properties of the log-return of the exchange rate are analysed and it is deemed to be iid. From the eleven distributional candidates we study is the fitted skew generalised t distribution proven to represent the data best after evaluation by criteria and statistics. Th…
O funkcji substytucji frazemów w reklamie prasowej
2022
Substytucja jest metodą modyfikacji formalnej frazemu, która ze względu na swoje walory komunikacyjne i ekspresywny charakter jest jednym z ulubionych środków językowych w reklamach prasowych. Jej popularność można wyjaśnić m.in. niewyczerpanymi możliwościami wyrazistych gier językowych o różnych stopniach trudności w odbiorze. Celem artykułu jest nie tylko prezentacja substytucji jako metody formalnej modyfikacji frazemu wywołującej efekty semantyczne, ale przede wszystkim omówienie jej funkcji w reklamie prasowej. Substytucja dzięki swojej kreatywności skupia uwagę odbiorcy, zachęca do lektury oraz wzmacnia koherencję tekstu ogłoszenia prasowego. Dzięki znajomości utartego sformułowania u…
The Euro and Monetary Policy Transparency
2002
This paper focuses on a possible explanation for the weakness of the euro, namely the lack of transparency of the European Central Bank's (ECB) monetary policy. In order to obtain a time-varying measure of monetary policy uncertainty in both the U.S. and Euroland, we estimate a Stochastic Volatility model using policy-adjusted short-term interest rates. We also analyze directly the impact of higher uncertainty on the euro-dollar exchange rate. The empirical findings are in line with those of other studies, and show that the U.S. Fed is more transparent than the ECB. This results in higher volatility of European interest rates, capital outflows, and a weaker euro vis-a-vis the U.S. dollar.
The role and presence of conflicts in romantic Erasmus relationships
2017
The present study assesses the presence and importance of conflicts in intercultural relationships that were created during an Erasmus exchange period abroad. The theoretical background is based upon the concepts of third culture building (TCB) and conflict management styles, both of which were used to explain the various stages of the relationship development. So far the scholarly literature on the subject of Erasmus students is rather scarce and only a few studies focus on intercultural couples’ lived experiences concerning conflicts. This study is driven by the need for more developed and valid information of Erasmus couples that in fact form a rather large number of the Erasmus students…
Overcoming Essentialism? Students’ Reflections on Learning Intercultural Communication Online
2022
The fields of intercultural communication (IC) and intercultural education are in flux and the paradigmatic shift is away from essentialist approaches on culture and interculturality towards seeing IC and interculturality as flexible, fluid, contradictory, political, and ideological constructs. This study presents a virtual exchange project, a joint introductory course on IC between a Finnish university and a French university. One of the objectives of the course was to provide students with a more critical, non-essentialist perspective on interculturality. This study presents an analysis of 32 students’ texts (learning logs) that are processed qualitatively using content analysis to find a…
Virtual Exchange: Future-ready teaching of multiliteracies across borders and cultures
2020
Virtual exchange is an online form of internationalization at home. Students from different countries collaborate in small, international groups on tasks joined by a common theme. They combine their expertise when solving problems together. The teachers act as mentors, providing facilitation and support for the students during the virtual exchange. The student teams work independently by selecting the tools for the collaboration, allocating the tasks and creating the group’s final product. Virtual exchange is a transnational learning opportunity which enables students to learn and practice how to efficiently combine and make use of their digital, visual, critical, linguistic and intercultur…
