Background:
While border screening measures were widely adopted by countries during the COVID-19 pandemic, a lack of consensus on the utility of border screening created a gap in best practice for its implementation. As such, countries adopted a diversity of approaches, providing an opportunity to evaluate the configuration and evolution of border screening systems. The
article addresses three questions: (i) how did countries configure their border screeningsystems for COVID-19? (ii) In what contexts did countries rely on public or private providers of these services? (iii) what do policies and narratives reveal about the perceived role of border screening in global public health? The article contributes to long-standing debates over the
private sector’s role in public health and the perceived value of border screening measures.


Methods:
This article presents results from an international comparative study based on tracking the organisation of border screening in eight countries. Secondary data was collected between  July 2021 – June 2022 from official government websites and policy publications, private sector sources where relevant, and trusted media sources in each study country. The
countries included are Australia, Canada, Germany, Ireland, South Africa, South Korea, Spain, and the United Kingdom.


Results:
All study countries used private provision for pre-departure diagnostic testing for international travellers. In contrast, screening of arriving travellers was more diverse. Countries that opted for private sector post-arrival screening saw governance challenges around accreditation and monitoring of providers, while public service provision saw challenges in capacity and high
resource costs. Travel was often framed as a ‘luxury,’ allowing states to shift responsibility for obtaining tests onto individuals; especially in the context of individuals travelling from low income to high income countries.

Conclusions:
The different approaches countries followed for screening of departing and incoming travellers suggests wealthy countries were more oriented towards defending their populations against disease importation, rather protecting the international community from disease exportation. These findings provide an opportunity to reflect on the purpose and
implementation of border screening. We emphasise a need for further discussion on the efficacy of border screening from both perspectives, given the tendency for countries to rely on these measures

German universities of Applied Sciences face declining student numbers and a growing shortage of skilled professionals in technical fields, prompting institutions in Bavaria to increasingly recruit international students, many of them from India. While this strategy stabilizes enrolment and supports national goals for securing a future workforce, it also introduces substantial challenges for teaching staff, administration, and students alike. Many incoming students bring competency profiles shaped by non-European higher-education systems, often marked by a strong emphasis on reproductive learning and limited experience with independent research, critical reflection, and scientific writing. High expectations of German master’s programs, combined with linguistic and cultural barriers, contribute to lower retention rates among international students and create additional burdens on teaching staff.

Drawing on experiences from four international master’s programs at Ansbach University of Applied Sciences, the paper analyses typical difficulties and evaluates measures designed to improve integration, academic success, and study conditions. Programs composed almost exclusively of Indian students tend to reproduce culturally homogeneous learning environments, which limit intercultural exchange, hinder discursive teaching formats, and reinforce established learning habits. In contrast, heterogeneously composed cohorts show better interaction, stronger language development, and improved academic performance. To counteract homogeneity, targeted interventions such as international poster sessions, mixed laboratory groups, and joint courses between German- and English-taught programs were introduced with positive but context-dependent outcomes.

Major challenges arise in the areas of scientific practice, rule compliance, and the unreflected use of AI tools, often rooted in a lack of prior exposure to principles of good scientific practice. The university responded with measures such as training units on academic integrity, adapted assessment formats emphasizing transfer performance, and workshops on literature research and academic writing. Additional structural factors such as particularly limited access to affordable local housing, negatively affect class attendance. Attempts to mitigate this included schedule adaptations to public transport and the introduction of block courses with mandatory practical components.

The paper concludes that successful internationalization requires more than English-language programs. It demands comprehensive support structures, including language training, intercultural competence development for staff, and institutional services tailored to international students’ needs. Given the intensive advising workload, smaller learning groups and recognition of international teaching efforts in workload models are essential. Only through sustained institutional commitment, adequate resources, and openness on all sides can internationalization efforts translate into improved learning outcomes and long-term integration.

  • Vor dem Hintergrund sinkender Studierendenzahlen und des Fachkräftemangels in den technischen Berufen in Deutschland, rekrutieren die Hochschulen in Bayern zunehmend Studierende aus dem Ausland. Dabei stoßen die angebotenen internationalen Studiengänge besonders bei Studierenden aus Indien auf großes Interesse. Andersartige Kompetenzprofile aus dem außereuropäischen Bachelorstudium in Kombination mit sehr hohen Erwartungen der Studierenden an ein Masterstudium in Deutschland führen zu enormen Herausforderungen bei allen Beteiligten. Förderlich für den erfolgreichen Studienverlauf ist es, Maßnahmen zur Gruppendurchmischung zwischen ausländischen und deutschen Studierenden wie internationale Postersessions und gemeinsame Studienangebote zu implementieren. Darüber hinaus ist es erforderlich, Regeln der guten wissenschaftlichen Praxis klar zu kommunizieren und deren Befolgung einzufordern. Nicht zuletzt ist die Stärkung der Sprachkompetenz ein Schlüssel für ein erfolgreiches Studium.

Engineers and scientists, i.e. STEM educated persons, are seen as strong drivers for technology and knowledge-driven growth and productivity in the high-tech sector including ICT services. However, since 2020 there has been a decline in the absolute number of new entrants to STEM courses.

In 2023, the Federal Statistical Office of Germany reported that 6.5% fewer students had enrolled on STEM courses in Europe. By contrast, countries in the Arab world and East Asia were able to significantly increase the proportion of STEM graduates.

A variety of measures are needed to make STEM attractive to students. This paper explains a package of measures to systematically familiarize children and young people with STEM and thus allay their fears of studying science and engineering. Over the past eight years, the Faculty of Engineering at Ansbach University of Applied Sciences has developed a concept in which participants from pre-school age to high school graduates are addressed with all their senses in age-appropriate laboratory experiments. The Ansbach model for promoting STEM acceptance begins with children of pre-school age by playfully awakening their natural curiosity. In child-friendly experiential spaces at the university, children experience themselves as researchers. In workshop topics from the fields of microbiology, food technology, and molecular biology, which become increasingly complex with the level of education, pupils are introduced to engineering and scientific issues in an age-appropriate way. It is always about experiencing science with all the senses and thus opening up not only a cognitive but also an emotional awareness for STEM.

To reduce the heavy time burden on individual members of the university, the measures are coordinated within the faculty and realized with the involvement of as many faculty members as possible in a modular way resulting in approximately four to six person weeks to attract 400 pupils per year.

Im Verlauf der Covid-19-Pandemie wurden in Deutschland nicht-pharmakologische Maßnahmen zur Infektionskontrolle entwickelt und implementiert. Dieser Beitrag analysiert die Akzeptanz sowie die Befolgung dieser Maßnahmen durch die deutsche Bevölkerung und untersucht statistisch signifikante Zusammenhänge in Bezug auf Alter, Geschlecht und Bildungsabschluss. Die zugrundeliegenden Daten wurden in einer qualitativen Befragung im Zeitraum März 2022 bis Mai 2022 erhoben. Die Ergebnisse zeigen drei statistisch signifikante Korrelationen: Die Wahrnehmung der AHA+L+A-Regel (Tragen von Alltagsmasken, Einhalten der Hygiene und Mindestabstands, Lüften, Nutzung der Corona-Warnapp) sowie die Nutzung einer Covid-19-App korrelieren mit dem Bildungsabschluss der Befragten, die Einstellung zur 3G-Regel (Zutrittserlaubnis bei vorhandener vollständiger Impfung, Genesung oder negativer Testung) korreliert mit dem Alter. Diese Ergebnisse können dazu beitragen, gezieltere Strategien zur Kommunikation und Entwicklung von Präventivmaßnahmen für den Bevölkerungsschutz zielgruppenspezifisch zu etablieren

  • Sinkende Studierendenzahlen im MINT-Bereich stellen ein Problem für die Hochschulen und die Gesellschaft dar. Die Ursachen liegen u.a. darin, dass sich die Schülerinnen und Schüler den MINT-Anforderungen zunehmend nicht gewachsen fühlen oder diese wenig attraktiv finden. Beidem kann durch zielgruppenspezifische Angebote an den HAWs begegnet werden. In der Fakultät Technik der Hochschule Ansbach wurde im Verlauf der letzten acht Jahre ein Konzept entwickelt, in dem Teilnehmende vom Vorschulalter bis zum Abitur altersgemäß in Laborversuchen mit allen Sinnen angesprochen werden. Das Maßnahmenpaket besteht aus verschiedenen Präsenzangeboten vom einfachen spielerischen Experimentieren für Vorschulkinder bis hin zu Vertiefungsworkshops und Schnupperangeboten für Teilnehmende aus den Oberstufen. Um die hohe zeitliche Belastung der einzelnen Hochschulangehörigen zu reduzieren, werden die Maßnahmen fakultätsintern koordiniert und unter Einbeziehung möglichst vieler Fakultätsmitglieder realisiert.

The non-conventional yeast Yarrowia lipolytica is attracting increasing attention due to its potential to produce large amounts of organic acids from hydrophobic substrates. Due to the steadily increasing demand for citric acid in the industrial sector, the aim of this scientific work was to develop a predictive model of the citric acid productivity of the strain Yarrowia lipolytica DSM3286. As a basis for this, the optical density, pH, cell number and citric acid were determined in 18 identical mixtures.

The citric acid concentration (mean values of the measured concentration over time) follows a linear increase. Based on this, the mathematical calculation operation of linear regression was selected for modeling the prediction model in Python. The following coefficients were determined for the variables used in the learning algorithm:

•       time:                      6,104 * 10-4

•       OD:                        -1,224 * 10-1

•       pH value:              -4,043 * 10-1

•       Cell count:            1,749 * 10-8

In final validation of the program, a result accuracy of 86.5% was obtained. The result obtained in the present scientific work shows that by means of simple linear regression, over a cultivation period of 13 days, a prediction of the citric acid productivity of strain Yarrowia lipolytica DSM3286 is possible.
