Human mobility contributes to the fast spatiotemporal propagation of infectious diseases. During an outbreak, monitoring the infection on either side of an international border is crucial as cross-border migration increases the risk of disease importation. Due to the unavailability of cross-border mobility data, mainly during pandemics, it becomes...

During pandemics like COVID-19, both the quality and quantity of services offered by businesses and organizations have been severely impacted. They often have applied a hybrid home office setup to overcome this problem, although in some situations, working from home lowers employee productivity. So, increasing the rate of presence in the office is...

While biological invasions are recognized as a major threat to global biodiversity, determining non-native species’ abilities to establish in new areas (species invasiveness) and the vulnerability of those areas to invasions (community invasibility) is challenging. Here, we use trait-based analysis to profile invasive species and quantify the commu...

BACKGROUND Long-term care facilities have been widely affected by the COVID-19 pandemic. Empirical evidence from the first wave of the COVID-19 pandemic demonstrated that elderly people are the most impacted and are at higher risk of mortality after being infected with SARS-CoV-2. Regularly testing care facility residents is a practical approach to...

The royal charters and chronicles present a unique historical source for researching power distribution and administration of the medieval kingdom. This paper presents an attempt to progress in the analytical approaches presented by German historians from the 1980s and 1990s to study the governance of the medieval kingdom. Inspired by the use of ne...

During the COVID-19 pandemic, many organizations (e.g. businesses, companies, government facilities, etc.) have attempted to reduce infection risk by employing partial home office strategies. However, working from home can also reduce productivity for certain types of work and particular employees. Over the long term, many organizations therefore f...

While biological invasions are recognized as a major threat to global biodiversity, determining species' abilities to invade new areas (species invasiveness) and the vulnerability of those areas to invasions (community invasibility) are still poorly understood. Here, we used trait-based analysis to profile invasive species and quantify the communit...

Different types of spatial analyses and visualizations can be used in the police practice for investigation, crime prediction, and planning of police forces. The public availability of crime data is one of the often discussed issues for the police, general public and academia. The efforts to open police data are rooted in the philosophy of the so-c...

Extended Abstract Spatial data collected by the police has considerable potential for spatial analysis. Such analysis can help to improve the performance of the police itself, raise public awareness of local issues, and serve as an input for decision making processes in other institutions. For these reasons we believe that police data should be, wi...
