Opis: Problematic mobile phone use can be related to negative mental states. Some studies indicate that behavioural dependency is related to variables associated with the country of origin. The aim of our study was to investigate if country indicators moderated the relationship between phubbing and psychological distress. Our sample consisted of 7,315 individuals from 20 countries, who completed the Phubbing Scale and the Kessler Psychological Distress Scale (K6). The analyses also included country indicators: the Gender Gap Index (GGI), the Human Development Index (HDI), the Social Progress Index (SPI), Hofstede’s dimensions of culture, and the World Happiness Index (WHI). Our results showed that psychological distress was related to at least one dimension of phubbing (i. e., to communication disturbance or phone obsession) in all countries, which means this relationship is culturally universal. The results of the study demonstrate the importance of testing measurement invariance to determine what type of analysis and what type of conclusion are valid in a given study or comparison. Moreover, the increasing or decreasing correlation between phubbing and distress is related to some culture-level indices.

Opis: One of the key factors afecting seed quality is microbial communities residing on and in the seeds. In this study, microbial populations of seeds of conventionally and organically produced wheat, barley, and maize were analyzed using two diferent approaches: the cultivation method and metagenomics. For cultivation, three basic media were used: DG18 (for fungi), and nutrient agar or tryptic soy agar supplemented with cycloheximide or nystatin (for bacteria). Metagenomic sequencing was performed using the Illumina MiSeq platform. A total of 452 bacterial isolates comprising 36 genera and 5 phyla and 90 fungal isolates comprising 10 genera and 3 phyla were obtained from the seed surfaces. Among bacteria, representatives from the genera Bacillus, Pantoea, Paenibacillus, and Curtobacterium predominated, and among fungi, Aspergillus predominated. A total of 142 fungal OTUs and 201 bacterial OTUs were obtained from all the samples. Proteobacteria, Firmicutes, Bacteroides, and Actinobacteria comprised most of the bacterial OTUs, and Ascomycota comprised most of the fungal OTUs. Only 3 fungal OTUs (representatives of Curvibasidium, Venturia, and Dermateaceae) were exclusively present only within seeds and not on the seed surfaces. Barley seeds had the highest microbial load and richness, whereas corn had the lowest. Wheat and barley shared a higher number of OTUs than either of them did with corn with higher overlap between conventionally grown cereals than between organically grown cereals. Some OTUs were farming specifc. This study demonstrates that the microbiome of cereal seeds is greatly dependent on the species of the host and is less afected by agricultural practices.

Opis: Companies are increasingly aware that employees are an important factor in success, so they pay more and more attention to them. Because of that, organizational culture and normative commitment are also included as ex-tremely important factors. The research includes a systematic and comprehensive review of the literature and at the same time obtaining and analysing data from practice through a survey. The research focuses on employees from the logistics departments in the supply chain of electronic component production and supply. Group of com-panies across Europe were included in the survey (Austria, Bosnia and Herzegovina, Bulgaria, Croatia, Czech Re-public, Germany, Hungary, Latvia, Lithuania, North Macedonia, Poland, Romania, Russia, Serbia, Slovenia and Ukraine). The research demonstrates the realization that the types of classification of organizational culture have different effects on direct and indirect normative commitment. Gender differences were also found. The re-search-based on the calculated average mean values shows the classifications of organizational culture and nor-mative commitment. The latter follows the organizational culture with minor deviations. The order of classifica-tion of organizational culture follows the current economic situation, where according to the studied criteria, the first is a culture of the market. The research shows that men’s rate of normative commitment is better than wom-en's, while in organizational culture the situation is exactly the opposite. One of the most significant findings is based on the Pearson correlation coefficient with the SPSS program was found that, according to the classifica-tion, Hierarchy culture has a positive effect on indirect normative commitment.

Opis: Sustainability gets higher on the policy agenda of many countries in terms of the UN Sustainable Development Goals. Unethical tax behaviour diminishes the tax system’s sustainability, but paying taxes is necessary if we want to contribute to society. There is a deeper need to understand the factors that influence taxpayers’ perceptions, personal values and personal tax culture. Previous research by the OECD (2013, 2019) using the World Values Survey (WVS) did not provide a sufficient explanation of all the socio-economic factors associated with personal tax culture. As the behaviour of an individual is shaped by a set of values, and values can provide predictive and explanatory power in the analysis of attitudes, opinions and actions by policymakers, it is necessary for them to understand such when proposing tax morale incentives within the institutional pillar. A literature review showed that the research topics on personal tax culture present specific assumptions and gaps. To contribute to this topic, a conceptual model was developed, and the relationship between personal values (conservation/self-enhancement), measured by the widely accepted and recognised Schwartz’s circular model, and personal tax culture was analysed with the aim of formulating recommendations for policymakers. The survey conducted in Slovenia involved 202 respondents. Based on exploratory factor analysis and the performed correlation analysis, empirical research suggests that a relationship between personal values and personal tax culture as the cornerstones of an individual’s tax-compliant behaviour and their attitude towards the ethics of tax evasion is significant. The correlation between personal values and an individual’s attitude towards the tax system is insignificant. By understanding the relationships between individuals’ personal and tax culture values, policymakers can achieve a greater sustainable tax system.

Opis: Pollinator health risks from long-lasting neonicotinoid insecticides like imidacloprid has primarily focused on commercially managed, cavity-nesting bees in the genera Apis, Bombus, and Osmia. We expand these assessments to include 12 species of native and non-native crop pollinators of differing levels of body size, sociality, and floral specialization. Bees were collected throughout 2016 and 2017 from flowering blueberry, squash, pumpkin, sunflower and okra in south Mississippi, USA. Within 30–60 minutes of capture, bees were installed in bioassay cages made from transparent plastic cups and dark amber jars. Bees were fed via dental wicks saturated with 27% (1.25 M) sugar syrup containing a realistic range of sublethal concentrations of imidacloprid (0, 5, 20, or 100 ppb) that are often found in nectar. Bees displayed no visible tremors or convulsions except for a small sweat bee, Halictus ligatus, and only at 100ppb syrup. Imidacloprid shortened the captive longevities of the solitary bees. Tolerant bee species lived ~10 to 12 days in the bioassays and included two social and one solitary species: Halictus ligatus, Apis mellifera and Ptilothrix bombiformis (rose mallow bees), respectively. No other bee species tolerated imidacloprid as well as honey bees did, which exhibited no appreciable mortality and only modest paralysis across concentration. In contrast, native bees either lived shorter lives, experienced longer paralysis, or endured both. Overall, longevity decreased with concentration linearly for social bees and non-linearly for solitary species. The percentage of a bee’s captive lifespan spent paralyzed increased logarithmically with concentration for all species, although bumble bees suffered longest. Of greatest concern was comparable debilitation of agriculturally valuable solitary bees at both low and high sublethal rates of imidacloprid.
