Why Digital Games Can Be Advantageous in Vocabulary Learning
2021
Vocabulary learning is an integral part of language learning; however, it is difficult. Although there are many techniques proposed for vocabulary learning and teaching, researchers still strive to find effective methods. Recently, digital games have shown potentials in enhancing vocabulary acquisition. A majority of studies in digital game-based vocabulary learning (DGBVL) literature investigate the effectiveness of DGBVL tasks. In other words, there are enough answers to what questions in DGBVL literature whereas why questions are rarely answered. Finding such answers help us learn more about the structure of the DGBVL tasks and their effects on vocabulary learning. Hence, to achieve this…
Consensus statement on the problem of terminology in psychological interventions using the internet or digital components
2020
Since the emergence of psychological interventions delivered via the Internet they have differed in numerous ways. The wealth of formats, methods, and technological solutions has led to increased availability and cost-effectiveness of clinical care, however, it has simultaneously generated a multitude of terms. With this paper, we first aim to establish whether a terminology issue exists in the field of Internet-delivered psychological interventions. If so, we aim to determine its implications for research, education, and practice. Furthermore, we intend to discuss solutions to mitigate the problem; in particular, we propose the concept of a common glossary. We invited 23 experts in the fie…
2019
Worries about possible harmful effects of new technologies (modern health worries) have intensely been investigated in the last decade. However, the comparability of translated self-report measures across countries is often problematic. This study aimed to overcome this problem by developing psychometrically sound brief versions of the widely used 25-item Modern Health Worries Scale (MHWS) suitable for multi-country use. Based on data of overall 5,176 individuals from four European countries (England, Germany, Hungary, Sweden), Ant Colony Optimization was used to identify the indicators that optimize model fit and measurement invariance across countries. Two scales were developed. A short (…
Innovations and Growth: Evidence from Finnish SMEs
2019
The purpose of this study is to clarify the factors that affect the ability of small and medium-sized enterprises (SMEs) to create innovations that promote firm growth. Studies regarding the relationship between research intensity and growth have typically produced mixed results, revealing a modest or non-existent influence of innovations on sales growth. These studies have typically used patents as indicators of innovation. We directly asked firms whether their innovations had affected their growth, and we regressed the results over several variables, covering a wide range of dimensions related to (1) personal factors, (2) firm-related factors (including questions that reflect a firm’s in…
Correlation between school dropout and gross domestic product in the emerging countries of Central and Eastern Europe
2020
By school dropout is meant leaving the educational system, regardless of the reached level, before obtaining a qualification or a complete proffesional training or before the end of the study cycle started (Doron & Parot, 2006). Although there are numerous researches on school dropout, we consider that it is necessary to study the relationship it has with the level of development of a country, in order to identify new causes and possible solutions to this phenomenon. In this study we included seven emerging countries of Central and Eastern Europe: Bulgaria, Czech Republic, Poland, Romania, Slovakia, Slovenia and Hungary. Thus, we analyzed the correlation between the annual gross domesti…
Schatten über der Schwarzarbeit
2008
Die Diskussion uber Messung, Grosenordnung und Konsequenzen der Schwarzarbeit steht bereits deshalb unter einem Schatten, der den Blick dafur truben kann, weil Enste und Schneider trotz jahrelanger Befassung mit dem Thema Schwarzarbeit und Schattenwirtschaft nicht systematisch zu unterscheiden vermogen. Ihre Schatzungen fur die Dimension des Phanomens beruhen zudem generell auf wissenschaftlich nicht haltbaren Vorgehensweisen, die sie gleichwohl repetitiv anwenden. Die unterstellten Einnahmenverluste beim Staat ergeben sich im Ubrigen lediglich bei Vernachlassigung mikrookonomisch bedeutsamer Budgetrestriktionen sowie durch Auserachtlassung zwingender makrookonomischer Kreislaufzusammenhang…
Die volkswirtschaftliche Bedeutung von Schwarzarbeit
2007
Die Schwarzarbeit wird in der finanzpolitischen Diskussion in Deutschland als volkswirtschaftlich gewichtig angesehen, und es werden ihr erhebliche Einnahmenverluste des Staates zugeschrieben. Die vorliegende Arbeit hinterfragt diese Behauptungen. Nach einer Definition der Schwarzarbeit und ihrer Abgrenzung gegenuber ahnlichen Sachverhalten wird die unterstellte volkswirtschaftliche Bedeutung zuruckgewiesen. Auserdem lasst sich im Rahmen einer konsistenten okonomischen Analyse zeigen, dass dem Staat durch Schwarzarbeit keinerlei Einnahmeausfalle entstehen. Nach allem ist das Ausmas der Schwarzarbeit in Deutschland gering, wobei gleichwohl allokative Wirkungen der Schwarzarbeit nicht auszusc…
Territorial determinants and NUTS-3 regional performance: a spatial analysis for Italy across the crisis
2018
This paper analyses the differential impact of several territorial determinants of the economic performance of Italian provinces (NUTS 3 level). as measured by per capita GDP, export and employment growth from 1999 to 2014. It covers both the pre‐crisis and the crisis period and stresses the role of geographical proximity in shaping local performance over a wide set of explanatory variables. In order to do so, we employ, firstly, a spatial Durbin model which enables us to discriminate between direct and indirect effects and to highlight the possible contagion or crowding‐out spatial effects for each territorial dimension affecting growth. Then, we extend the analysis by allowing for the pos…
Fuzzy Portfolio Selection Models for Dealing with Investor’s Preferences
2017
This chapter provides an overview of the authors’ previous work about dealing with investor’s preferences in the portfolio selection problem. We propose a fuzzy model for dealing with the vagueness of investor preferences on the expected return and the assumed risk, and then we consider several modifications to include additional constraints and goals.
Drone arc routing problems
2018
[EN] In this article, we present some drone arc routing problems (Drone ARPs) and study their relation with well-known postman ARPs. Applications for Drone ARPs include traffic monitoring by flying over roadways, infrastructure inspection such as by flying along power transmission lines, pipelines or fences, and surveillance along linear features such as coastlines or territorial borders. Unlike the postmen in traditional ARPs, drones can travel directly between any two points in the plane without following the edges of the network. As a consequence, a drone route may service only part of an edge, with multiple routes being used to cover the entire edge. Thus the Drone ARPs are continuous o…
