Machine learning analysis of the effects of COVID-19 on migration patterns

This study investigates the impact of the COVID-19 pandemic on European tourist mobility patterns from 2019 to 2021 by conceptualizing countries as monomers emitting radiation to model and analyze their patterns through the lens of socio-economics and machine learning. By incorporating perturbations into clustering, this work evaluates the stability of mobility flux clustering under variable conditions, offering insights into the dynamics of socio-economic corridors. The results highlight distinct shifts in tourist behavior, with bimodal clustering in 2019 reflecting heterogeneous mobility patterns, whereas unimodal distributions in 2020 and 2021 indicate increased global uniformity, driven by pandemic-induced restrictions and gradual recovery. The PCA and dendrograms of the perturbed clustering reveal that tourist preferences align with GDP, cultural, and linguistic similarities, explaining regional cohesion and fragility. This study demonstrates the fragility of emerging socio-economic corridors like the Red Octopus compared to the resilience of established ones like the Blue Banana. The findings emphasize the importance of targeted policy interventions, such as strengthening transport infrastructure and fostering small and medium-sized enterprises (SMEs), to mitigate disruptions and promote balanced regional development. By integrating perturbations into clustering, this research introduces a strong framework for assessing mobility patterns under realistic variability to enhance economic resilience and anticipate shifts in tourist behavior during global crises.

EXPRESS: Does Location Familiarity Increase Response to Mobile Ads?

Targeting ads based on consumers’ real-time locations has evolved into a practice worth billions of dollars in the advertising industry. Yet, the implications of repeated mobile ad exposure are poorly understood, primarily due to the confounding effects of locational context. This paper seeks to bridge this gap. Using two large datasets comprising more than three million observations from a major European mobile telecommunication company, we investigate how ad repetition and location revisits (i.e., returning to a previously visited location) jointly determine consumer response to mobile display advertising. Our empirical strategy leverages coarsened exact matching combined with a logit model with fixed effects at the consumer-location level. We find that the click rate through ads is more than 26 percent higher at revisited locations compared to locations visited for the first time. However, mobile ad repetition decreases click rates, and this effect is amplified at revisited locations. Our results contribute to the theory and practice of mobile advertising.

The European Mobile Laboratory: key insights from a decade of outbreak response

Abstract EMLab has responded to emergencies including the West Africa Ebola virus outbreak (2014-2016), the COVID-19 pandemic, and outbreaks of yellow fever, Marburg virus, and Lassa fever. It has deployed mobile labs and experts to many countries, including Guinea, Liberia, Sierra Leone, Nigeria, Uganda, the Democratic Republic of the Congo, Germany, and Greece. With accumulated experience from each deployment, EMLab’s diagnostic expertise has evolved beyond RT-PCR and serological testing to include basic point-of-care tests, haematology, and genomic surveillance capacities, also focusing on interoperability with other response capacities such as EMTs. Critical to mission success, the organization works closely with the WHO and GOARN, and was certified in 2023 as an official German response capacity within the European Civil Protection Pool. The two-year continuous deployment from 2014-2016 was pivotal in shaping EMLab’s evolution, also leading to significant capacity-building efforts in West Africa. In Guinea, for example, a surveillance network of three diagnostic laboratories has been established and successfully detected cases of viral haemorrhagic fevers, including the re-emergence of Ebola virus and the first reported case of Marburg virus in Guinea in 2021. Ultimately, EMLab’s extensive experience demonstrates that effective public health emergency response requires constant evolution, strategic partnerships, and a commitment to building local capacities, paving the way for a more resilient and prepared global health community.

Electro-mobility – an Opportunity to Develop a More Sustainable Transport System

The future of transport is electro-mobility, a technology that ensures environmentally friendly and energy efficient vehicles on the road. But to exploit the full benefits of electric propulsion there are still many challenges to overcome. These challenges are related to the cost and residual value (aftermarket) of the vehicles, battery life and cost, charging and range. This article discusses these challenges as well as the state of the electric vehicle market. The aim is to present to what extent the development of electric mobility in Europe and in Bulgaria will outline a more sustainable transport system and to outline what the opportunities for its development are. Decarburization of transport is key to achieving sustainable mobility ensuring transport connectivity across the continent.

The selectivity of internal movers: An analysis of the relationship between education, social origin, and geographical mobility in Europe

This paper aims to analyse the social selectivity of internal movers in six European countries, by examining the influence of education and social origin on the likelihood of moving. The study, using ShareLife data, reveals country-specific variations in social selectivity. France and Poland show a skilled selection of internal movers, where education is the primary factor affecting the likelihood of moving, with no additional effect of social origin. In Germany and Sweden, internal movers are selected based on their social origin as well as education, but this double selection differs between the two countries, with a boosting scenario in Germany and a systematic effect of social origin in Sweden, regardless of educational level. Finally, in Spain and Italy, the social selectivity of movers is less evident. Overall, the study highlights the importance of considering the interplay of education and social origin in understanding the social selectivity of internal movers.

Russia's invasion of Ukraine and perceived intergenerational mobility in Europe.

In this study, we shed light on the social consequences the Russian invasion of Ukraine in 2022 has had in other European countries. We argue that positive perceptions of one's intergenerational mobility are linked with political and economic stability and that the war can thus be expected to impact intergenerational mobility perceptions. We test our pre-registered hypothesis with representative survey data from three European countries, the United Kingdom, Germany, and Sweden, which were significantly affected by the ongoing war. Our results show that individuals' war-related concerns in all countries are divided into proximal and distal concerns. In turn, proximal concerns go along with greater perceived downward and less perceived upward mobility in the United Kingdom and Germany. We interpret these findings by calling for expanding the horizons of intergenerational mobility research by incorporating areas of life other than socio-economic position.

Why Students Choose the European Project Semester Program for Academic Mobility: A Case Study at an Engineering School

European Mobility Programmes promoted by the European Commission have propelled a significant change in students’ mobility across Europe in the last few decades. The European Project Semester (EPS) is one of those programmes. Research has mainly focused on understanding the factors that shape students’ decision to engage in mobility experiences but has not tackled the motivation(s) leading them to opt for that programme in a particular country at a specific institution. This paper aims to understand EPS students’ motivation to elect this programme for their mobility at a particular country/city/institution and hence contribute to help institutions define policies and practices to attract more students to this specific programme. Carried out at the Polytechnic School of Engineering in Porto, a mixed research methodology was followed, considering qualitative and quantitative data equally, and a theoretical framework was devised based on the push–pull factors model. Seventy-seven students participated in the study by filling in a closed-question questionnaire and engaging in focus group sessions. The findings sustained previous research and highlighted that students’ motivation is supported by a combination of factors (personal, professional, academic), among which the personal category was the highest rated. These results show that the motivations for choosing the EPS programme do not differ considerably from those leading students to undertake regular mobility.

Students’ Voice: The Analysis of their Mobility Experiences through Interviews

The European student mobility Erasmus+ Programme was first established in 1987 and, in 1999, the Bologna Declaration aimed to promote the mobility as one of its main goals, focusing on intergovernmental cooperation in the field of higher education. In recent years, the mobility process has become increasingly significant, and a greater number of individuals experienced a mobility period abroad improving knowledge, skills, and attitudes. In addition to this, several international studies show how the Erasmus+ mobility has positive effects on social and individual growth. For this reason, the aim of this contribution is to focus the attention on the personal development of students from Sapienza University of Rome who spent a mobility period abroad in a non-EU country during the academic year 2019/2020 (last available and complete data before the COVID-19 outbreak). The results of the analysis, carried out by using content analysis, show how personal development as well as the ability to adapt to different contexts can be facilitated by an experience abroad. Furthermore, this can enable one to find a valuable job according to the skills and competences improved in a diverse study environment and can create a number of opportunities for personal growth.

Promoting dual careers at higher education institutions: 31 benefits ranked by the project Student Athletes Erasmus+ Mobility in Europe (SAMEurope).

The project Student Athletes Erasmus+ Mobility in Europe identified and defined a total of 31 benefits offered to dual-career student athletes who are combining their university studies with high-level training. The project was co-funded by the European Union and carried out by five universities: Chalmers University of Technology (Sweden), Institut national des sciences appliquées de Lyon (France), University of Jyväskylä (Finland), Karlsruhe Institute of Technology (Germany), and Universitat Jaume I (Spain). The purpose of the study was to rank these benefits by combining the perspectives of the university staff and the student athletes from each university in the consortium. The university staff included experts from sports services and the international relations office. A questionnaire was also sent to the dual-career athletes enrolled at the consortium's universities. Of the 514 dual-career athletes, 208 (116 women) completed the questionnaire. The overall response rate was 40.47%. The university staff assessed the importance of each benefit, how easy it was to implement at the institution, and whether or not the university offered the benefit to its students. The dual-career students rated each of the 31 benefits and indicated whether or not they had used them. A specific methodology was designed to rank these benefits using the ratings of the university staff and the student athletes. Intra-group and inter-group Pearson correlations were performed. The results show a strong and significant correlation between the benefits from the perspective of the university staff (r = 0.710, p = 7.76E-7) and from the perspective of the students (r = 0.715, p = 2.44E-6). The correlation is moderate and significant when the benefits are correlated from the perspective of the two groups as a whole (0.363, p = 0.045), with the three most important benefits being the free use of sports facilities, justification for absences, and the adaptation of the pace of studies. The study makes visible the commitment of higher education institutions to facilitating the dual career of student athletes and identifies those benefits that may be of greater interest to European universities as a whole. The European perspective has been considered, while respecting the specificities of each university and the country in which it is located.

Is Erasmus going green? The carbon footprint of European academic mobility and sustainability policies of European universities

The European Union has promoted academic mobility for almost half a century. A side effect of that has been a growing carbon footprint, as most academic mobility in Europe is done by air. Based on mobility data for 2014−2020, we analysed its spatial distribution and identified dominant destinations. Juxtaposing these results with research on higher education institutions’ environmental measures and policies, we have identified that the willingness to reduce the carbon footprint is emerging yet tenuous, and more declarative than actual. We recommend more decisive steps to reduce air travel within Europe, outlining the possibilities for carbon footprint reduction without harming European academic mobility itself.

The OPEVA Manifest: OPtimisation of Electrical Vehicle Autonomy, a Research and Innovation project

Electromobility is a critical component of Europe’s strategy to create a more sustainable society and support the European Green Transition while enhancing quality of life. Electrification also plays an important role in securing Europe’s position in the growing market of electric and autonomous vehicles (EAV). The EU-funded OPEVA project aims to take a big step towards deployment of sustainable electric vehicles by means of optimising their support in an ecosystem. Specifically, the project focuses on analysing and designing optimisation architecture, reducing battery charging time, and developing infrastructure, as well as reporting on the driver-oriented human factors. Overall, OPEVA’s goal is to enhance EAV market penetration and adoption, making them more accessible and convenient. The aim of this paper is to inform the European automotive, transportation, energy and mobility community be presenting the OPEVA manifestation, and the overall solution strategy solidified through the progress throughout the first year of the project.

Linguistic authority in the context of European mobility: addressing the empty promise of élite multilingualism

ABSTRACT This qualitative study examines linguistic authority in an international department of a European Union institution in Luxembourg. Using socio-pragmatic discourse analysis, it investigates language workers’ stances towards language use at work. The findings reveal manipulative effects of language ideologies – (élite) multilingualism and native speakerism – that promote a business-like understanding of the value of language(s) in a public institution. While the institution benefits from this setup, its negative effects seem more pronounced for (“routed”) workers in unstable situations of international mobility compared to those who are settled (“rooted”). The paper advocates for increased critical language awareness and seeks to sensitise stakeholders to the effects of language ideologies in professional settings. This discussion is particularly relevant for public institutions that promote multilingualism while using English as the common language of communication. However, it may also inspire other multilingual organisations in which management aims to enhance their employees’ work experience.

Why are lower socioeconomic background students underrepresented in Erasmus? A focus on the selection into mobility and degree course organization

ABSTRACT Disadvantaged students in higher education are significantly underrepresented in study abroad programs. Existing research has explored this socioeconomic disparity in student mobility, primarily by comparing mobile and non-mobile students. However, these studies often overlook the extensive selection process students undergo to join a mobility program, encompassing application phases, eligibility assessments, and ability evaluations. This study investigates how these selection steps contribute to the unequal uptake of higher education mobility in Europe, focusing on the European Union’s most popular study-abroad program ‘Erasmus’. Additionally, it explores how the program organization at the degree course level is associated with socioeconomic disparities in student mobility. Using administrative population data from a large Italian university, covering 46,000 graduates, the study finds that, on average, 90% of socioeconomic disparities in Erasmus mobility are due to disadvantaged students shying away from the application, while ability selection is only marginally important. Additionally, degree-level characteristics, particularly the social segregation across fields of study, matter. Although the study is based on data from a single university in Italy, it has implications for an international audience in countries with similar institutional settings for international student mobility, as it demonstrates for the first time the impact of the selection process and degree course organization on the socioeconomic gap in study abroad program participation.

Multidimensionality Matters: The Implications of Educational Hierarchy and Differentiation for Intergenerational Mobility in Europe

Taking the pulse about contact tracing apps on Twitter

Social media allow citizens to express their opinions on all aspects of life and society, and this trend has been enhanced during the COVID-19 crisis, when more “traditional” ways of opinion expression were not possible. To get the feeling of Twitter users’ opinions on topics of importance we analysed tweets and combined them with relevant news, thus allowing for potential event detection. We showcase the prototypical framework that we have developed with our findings about European COVID-19 mobile contact tracing apps in tweets posted between 09/07/2020 and 10/07/2021. We obtained both high-level results (for example, trending twitter activity, sentiment polarisation of important hashtags, etc.) and more specific ones (such as, the spatial distribution of tweets regarding a specific app), which indicate that our approach can be applied in the future to get useful insights on topics of public interest that result in active discussions on social media platforms.

Educational Status as a Mediator of Intergenerational Social Mobility in Europe: A Positional Analysis Approach

This paper investigates the transmission of educational attainment from parents to offspring as a mediator of intergenerational class mobility in Europe. The study covers the last two decades with data drawn from a cross-national large-scale sample survey, namely the European Social Survey (ESS), for the years 2002–2018. Interest has focused on the question of the persistence of inequality of educational opportunities by examining the attainment of nominal levels of education and the association between the educational attainment of the parent with the highest level of education and their descendants. The study also covers new trends in social mobility that consider education as a “positional good”, and a novel method of incorporating educational expansion into the transition probabilities is proposed, providing answers to whether the rising accessibility of educational qualifications attenuates the association between social origin and educational attainment. Therefore, the concept of positionality is taken into account in the estimation of intergenerational transition probabilities, and to complement the analysis, mobility measures are provided for both methods, nominal and positional. The proposed positional method is validated through a correlation analysis between the upward mobility scores (nominal and positional) with the Education Expansion Index (EEI) for the respective years. The upward mobility scores estimated via the positional method are more highly correlated with the EEI for all years, indicating a better alignment with the broader trends in educational participation and achievement.

Critical dimensions in the empirical measurement of common shareholding

The debate on common shareholding and its potential antitrust effects is currently on the agenda of major institutions worldwide. Discussions point to the need for improved empirical quantification of this phenomena. This work presents a flexible, multifaceted statistical framework for a set of new common shareholding indicators, covering both firm and investor perspectives, which can be adopted under different economic models. Many indices currently used in the literature fall within this framework as special cases. Aggregation at market level yields suitable industry-level indicators, providing policymakers with tools to evaluate the extent of common ownership in strategic markets. The indices are tested using firm-level data for European Mobile Network Operators in 2007–2021, showing a sector with concentrated ownership under large corporate groups, but also the presence of institutional investors with extensive ownership across the major firms.

European Mobility Programs and Skills Development

This specific study follows the quantitative methodology approach and seeks to investigate primary education teachers’ perceptions of the skills developed through participation in European mobility programs. It examines whether there is a correlation between the perceptions of the following professional characteristics: knowledge of a foreign language, knowledge of information and communications technology (ICT), and participation in training programs for mobility. The research was conducted in the prefecture of Achaia in May 2023. The convenient sampling technique was applied, and 360 teachers finally completed the electronic questionnaire. Regarding data analysis, descriptive and inductive statistics were applied with the application of IBM SPSS v28 software. The internal consistency reliability for skills development from the European mobility programs is very satisfactory (Cronbach’s Alpha = 0.904 > 0.70). Based on the findings of this study, it is shown that teachers recognize, to a very high extent, that they develop precious skills while participating in European mobility programs. Finally, their perceptions are reinforced by specific vocational traits.
