Omissions by design in a survey : is this a good choice when using Structural Equation Models?
Paula Cristina Ribeiro Vicente, 2024, izvirni znanstveni članek

Opis: Missing observations can arise due to the effort required to answer many questions in long surveys and the cost required to obtain some responses. Implementing a planned missing design in surveys helps reduce the number of questions each respondent needs to answer, thereby lowering survey fatigue and cutting down on implementation costs. The three-form and the two-method design are two different types of planned missing designs. An important consideration when designing a study with omissions by design is to know how it will affect statistical results. In this work, a simulation study is conducted to analyze how the usual fit measures, root mean square error of approximation (RMSEA), standardized root mean square residual (SRMR), comparative fit index (CFI), and Tucker-Lewis index (TLI) perform in the adjustment of a Structural Equation Model. The results revealed that the CFI, TLI, and SRMR indices exhibit sensitivity to omissions with small samples, low factor loadings and large models. Overall, this study contributes to our understanding of the importance of considering omissions by design in market research.

Domestic cat - the unspoken threat to wildlife in the sub-urban location of Maribor
Larisa Bedrač, Nina Šajna, 2024, izvirni znanstveni članek

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.

Effect of usage of industrial robots on quality, labor productivity, exports and environment
Jasna Prester, Iztok Palčič, 2024, izvirni znanstveni članek

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.

Possibilities and concerns of implementing precision agriculture technologies on small farms in Slovenia
Jurij Rakun, Erik Rihter, Damijan Kelc, Denis Stajnko, Peter Vindiš, Peter Berk, Peter Polič, Miran Lakota, 2022, izvirni znanstveni članek

Opis: Precision agriculture (PA) through the use and utilization of innovative technologies is a concept in agricultural management that enables long-term efficiency gains, control of unforeseen changes, and a reduction of negative impacts on the environment. However, there are even more reasons and benefits to using precision agriculture technologies (PATs) on farms, but the actual use on small farms is often questionable. The main objective of this research was to evaluate and analyze the current state of PA and its potential on a set of small farms. In addition, a comparison was made between small farms located in less favored areas (LFAs) and more favored areas (MFAs) to find if specific characteristics of the surrounding environment affect the (non-) implementation of these technologies by farm owners, with respect to the given regional possibilities. The result shows that 57.5% of respondents on these farms have never implemented PATs before and 20% are beginners in their respective fields. It was found that there were no statistically significant differences in the integration between fewer LFAs and MFAs technologies and their use in this study. The majority of respondents believe that the main changes need to occur on the level of politics. The results show that the level of cost or initial investment is the main reason and the main obstacle in the implementation of PATs on the surveyed farms.

Simultaneous use of digital technologies and industrial robots in manufacturing firms
Klemen Kovič, Robert Ojsteršek, Iztok Palčič, 2023, izvirni znanstveni članek

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.

Frost protection measures : survey results
Matej Fike, Miha Smrekar, Mateja Fekonja, 2021, izvirni znanstveni članek

Opis: In Slovenia, frosts occur often and it causes great damage for growers. Various passive and active methods are known for frost protection. Pasive methods can be implemented throughout the year. They are used to enable easier implementation of active methods, which are in use when a period of frost occurs. The aim of this research is, with the help of a survey, to assess whether growers in Slovenia implement active or passive methods of frost protection, and if not, why not. The survey contained 24 questions and was intended primarily for fruit and wine growers in Slovenia. The results of the survey show that frost happens to Slovenian growers on average every other year, and destroys on average 50% of their crop. Despite frequent frosts and the damage they cause, growers are not implementing any active measures, nor are they willing to invest in them. The reasons for this may be the large investments required for active measures, the small sizes of farms in Slovenia (on average 12 ha according to the survey answers), or that farmers are insufficiently informed about the various measures.

Spatial clusters of Varroa destructor control strategies in Europe
Robert Brodschneider, Johannes Schlagbauer, Iliyana Arakelyan, Aleš Gregorc, 2022, izvirni znanstveni članek

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.

The use of statistical methods in Croatian enterprises during the early stages of COVID-19
Berislav Žmuk, 2022, izvirni znanstveni članek

Opis: The appropriate application of statistical methods in enterprises should have an important role in business decision-making processes. However, Croatian enterprises still tend to have certain resistance to statistical methods. The new challenges introduced by the COVID-19 pandemic emphasised the importance of conducting statistical analyses as support for making business decisions. In order to investigate the situation and attitudes towards the use of statistical methods, primary research was conducted in the form of a web survey on a sample of 768 Croatian enterprises, of which 40% use statistical methods in their business. The research revealed the level of statistical methods use in Croatian enterprises, demonstrated which statistical methods Croatian enterprises prefer, and defined who is most responsible for their use. Furthermore, the reasons for the use of statistical methods and the major obstacles to the use of more intensive statistical methods were also investigated. The results are described and discussed on an overall level and by considering the size of the enterprises.

Prevention of juvenile crime and deviance : Adolescents' and experts' views in an international perspective
Thomas Görgen, Anneke Evenepoel, Benjamin Kraus, Anabel Taefi, 2013, izvirni znanstveni članek

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.
