Opis: The monitoring of domestic cats' prey brought home was conducted between the 13th of March and the 1st of May 2023 in two residential areas near Maribor, Slovenia. This study aimed to provide information about the amount, diversity, and frequency of prey that the cats captured to identify the predatory impact of domestic cats in peri-urban areas. We present the results of the prey return, whether the prey was brought alive or not, and whether it was eaten or not. We further provide information about the predation frequency of domestic cats concerning circadian activity according to weather conditions and air temperature. The frequencies of various taxonomic groups of prey captured were described in relation to land use in a location and species' biology. Our results include a total of 50 records of 12 species (3 species of birds and 9 of mammals). Domestic cats were more active during the mornings and on days without rain, and the frequency of bringing home prey increased with higher temperatures.

Opis: Industrial robots are slowly finding their way into manufacturing companies. This paper examines the impact of robots on productivity, exports, quality, sustainability and labor in European manufacturing companies. There is little research on the use of industrial robots and their impact in developed countries. Most research relates to Chinese companies, and often, the data are outdated. The data in this paper come from the European Manufacturing Survey project, which was conducted in 2022 and includes 476 manufacturing companies. The results of the impact of industrial robots on quality, labor productivity, exports and green technologies are determined using a T-test between companies that use industrial robots and those that do not. However, the impact of higher investment in environmental technologies by industrial robot users was examined by a two-stage OLS regression analysis with control variables representing the contextual characteristics of the companies. The results show positive effects on all of the variables. The results show that the greater use of robots occurs in industries with low-to-medium technology intensity, that robots contribute to labor productivity and exports and that companies that use robots also tend to use environmentally friendly technologies.

Opis: This paper presents the use of digital technologies and industrial robots in manufacturing firms. More importantly, we look at the relationship between the use of digital technologies and industrial robots within the Industry 4.0 concept. We also use a specific Industry 4.0 Readiness index to assess manufacturing firms’ Industry 4.0 readiness level and analyze the relationship between the achieved readiness level and the use of industrial robots. The research is based on data from 118 manufacturing firms from a European Manufacturing Survey. Based on statistical analysis, we present the results that show a significant correlation between the use of specific digital technologies and two types of industrial robots. Our study also points out that manufacturing firms with a higher Industry 4.0 readiness level tend to use industrial robots more frequently.

Opis: Beekeepers have various options to control the parasitic mite Varroa destructor in honey bee colonies, but no empirical data are available on the methods they apply in practice. We surveyed 28,409 beekeepers maintaining 507,641 colonies in 30 European countries concerning Varroa control methods. The set of 19 different Varroa diagnosis and control measures was taken from the annual COLOSS questionnaire on honey bee colony losses. The most frequent activities were monitoring of Varroa infestations, drone brood removal, various oxalic acid applications and formic acid applications. Correspondence analysis and hierarchical clustering on principal components showed that six Varroa control options (not necessarily the most used ones) significantly contribute to defining three distinctive clusters of countries in terms of Varroa control in Europe. Cluster I (eight Western European countries) is characterized by use of amitraz strips. Cluster II comprises 15 countries from Scandinavia, the Baltics, and Central-Southern Europe. This cluster is characterized by long-term formic acid treatments. Cluster III is characterized by dominant usage of amitraz fumigation and formed by seven Eastern European countries. The median number of different treatments applied per beekeeper was lowest in cluster III. Based on estimation of colony numbers in included countries, we extrapolated the proportions of colonies treated with different methods in Europe. This suggests that circa 62% of colonies in Europe are treated with amitraz, followed by oxalic acid for the next largest percentage of colonies. We discuss possible factors determining the choice of Varroa control measures in the different clusters.

Opis: Purpose: This article analyses perspectives on youth crime prevention in samples of 13–17 year old students from 6 European countries and of practitioners/experts in Belgium and Germany. Design/Methods/Approach: Surveys were conducted among urban and rural school students (n = 10682). Expert and practitioner perspectives were taken into account using Delphi surveys, standardized surveys on the state of youth crime prevention, and semistructured interviews with practitioners in the areas where the school surveys were conducted. Findings: While the majority of students have been targeted by drug abuse prevention measures, rates for violence prevention are lower. Students ascribe moderate preventive potential to school and they regard peers and parents as most influential in prevention while professional agents are viewed as less important. Punitive approaches are not rejected, but approaches focusing on individual resources and problems are given priority. Experts point at the significance of socioeconomic factors related to the problem of (youth) delinquency and hence of social policy measures. They recommend prevention starting at an early age, strengthening social skills and following multi-professional approaches. Research Limitations / Implications: Schools surveys excluded special schools, and response rates in expert surveys were low or moderate. Practical Implications: Findings point to young persons’ understanding of factors influencing their behaviour and at connections between involvement in offending and accessibility for approaches to prevention. Expert surveys show needs for improvement in the field of prevention, especially in terms of funding, evaluation, and fundamental strategic approaches. Originality/Value: Perspectives of both actors and targets of preventive approaches are taken into account.
