Abstract: Slovenia has a unique blend of climatic, soil, geographic and historical factors that fostered a rich tradition of plum cultivation and utilization. This study was set up to achieve following objectives: 1. assess the genetic diversity of 124 accessions of the three Prunus species (P. domestica L., P. cerasifera Ehrh., and P. spinosa L.); explore the possible contribution of P. cerasifera and P. spinosa to the ancestry of P. domestica; examine the genetic relationships and variability among the prevalent P. domestica material distributed in Slovenia. A combination of genetic markers, including 11 SSRs (UDP96-005, BPPCT034, EMPAS12, UCD-CH17, EMPAS06, EMPAS11, EMPAS14, BPPCT014, BPPCT025, CPSCT026 and CPPCT006) and three universal cpDNA markers (HK, K1K2 and VL), were chosen alongside flow cytometry. The analysis identified ten cpDNA haplotypes, which were grouped into three clusters using Unweighted Neighbor-Joining (NJ) analysis. All 11 SSR primer pairs exhibited polymorphism, revealing 116 unique genotypes and a total of 328 alleles, indicating considerable diversity with an average of 29.82 alleles per locus. Bayesian analysis distinguished two ancestral populations across all analyzed species. Principal Coordinate Analysis (PCoA) reflected the clustering observed in the Bayesian analysis. When analyzing individual set of P. domestica material, Bayesian analysis also distinguished two ancestral populations across, with PCoA confirming the results of Bayesian analysis. The NJ analysis categorized 71 P. domestica accessions into three clusters with numerous subgroups, reflecting a high genetic diversity. The majority of accessions aligned with traditional pomological groups, such as common prunes, mirabelle plums and greengages. Genetic diversity parameters were analyzed for the 42 diploid P. cerasifera genotypes. A relatively high diversity levels were found, resulting in 135 alleles, with high average values for alleles per locus (10.38), effective number of alleles (Ne = 5.22), expected heterozygosity (He = 0.77), observed heterozygosity (Ho = 0.64) and PIC value (0.754). In addition, 32 private alleles were found in 20 accessions. Bayesian analysis of the P. cerasifera material revealed three ancestral populations, corroborated by Principal Coordinate Analysis, while an NJ analysis grouped the accessions into three clusters based on the origin of the accession. This study identified valuable local landraces within the P. domestica pool, including traditional prunes or Bluish plums, which are of great genetic interest. Furthermore, the integration of complementary methods facilitated the differentiation of the three species and provided insights into the origin of plum. The findings will be crucial in comprehending the diversity of Slovenian plum germplasm, improving conservation efforts, recovering local genotypes and enriching existing collections of plant genetic resources.

Abstract: The purpose of the study is to examinewhether two differentwork commitment profiles influence service quality in the hospitality sector in Slovenia and Serbia and how the implications of the differences can be used in the tourism and hospitality industry. Combining a qualitative and quantitative approach, two new instruments were developed for this study. The first instrumentwas created on the basis of short, structured interviews with employees. Two factors explaining the two different commitment profiles were determined with statistical analysis and with themethod of clustering, four dimensions of commitment profiles formingwere extracted. The second instrument was developed on the basis of existing evaluation forms for employees in the tourism industry and interviews with leading and middle managers of hotels. The findings of the study show that there is a small proportion of professionallyoriented employees in the tourism sector, and the difference among employees is evident in the ranking of working values. These results could be useful formanagers in planning and organising their human resources and also in planning further development of their companies% human resource policies. The original contribution of the article is the ranking of working values and the perception of quality work by employees in the hospitality sector. The study also reveals new evidence on different types of commitment profiles.

Abstract: Webinar “Tools supporting academic integrity” with presentations on: Experiences in Establishing National Plagiarism Detection Systems Academic Integrity and Plagiarism on Slovenian Academic Institutions (Ojsteršek Milan) The Slovenian open access infrastructure consists of Slovenian universities repositories, a repository for research organisations, a repository for standalone faculties and a national portal (http://openscience.si/) that aggregates content from the repositories and other Slovenian archives (dLib.si, videolectures.NET, digital library of Ministry of Defence, Social Science data archive, ScieVie repository…). The national portal provides a common search engine, recommendation of similar publications, and similar text detection. During the setting up of the national open access infrastructure, the rules and processes for mandatory submissions of electronic theses, dissertations, research publications and research data were defined. One of the features is the use of software for plagiarism detection during the process of submitting electronic theses, dissertations and research publications. Technical characteristics of the plagiarism detection system used in the Slovenian national open access infrastructure will be presented. We will also describe established processes for awareness, prevention and detection of plagiarised documents. Finally, we will present chronologically organised data about the similarity of documents from the test corpus of documents, published on the internet after the year 2000. Nationwide Barrier to Plagiarism is Bearing Fruit (Kravjar Július) Plagiarism is a phenomenon that existed in the past, exists today and will exist in the future. Slovakia with its population of 5.4 million is confronted with plagiarism like other countries. The dynamics of changes in higher education, in ICT and internet penetration while at the same time a low level of ethics, copyright and intellectual property rights awareness in our country, contributed to the spread of plagiarism – an unwanted kind of “creativity“ after the year of revolutionary changes (1989). And there was an inherent lack of systemic action to create a barrier for future growth of plagiarism. The absence of a broader discussion of academic ethics (AE) had its consequences: the members of the academic community and the general public do not fully understood the importance of AE, hence they were less sensitive to the violations of AE. There were 13 higher education institutions (HEIs) in Slovakia in 1989, the number has now grown to 39, the number of students increased from 63 thousand to about a quarter of million and the teaching staff growth was insignificant. In 2008 MinEdu decided to acquire a plagiarism detection system (PDS) and create a central repository of theses and dissertations (CR) for all Slovak HEIs. It was the milestone for the nationwide CR and for PDS – both systems are known under the name SK ANTIPLAG. The preparation of the legislative environment (the amendment to the Higher Education Act, 2009) represented the fundamental prerequisite for the breakthrough in the fight against plagiarism and created an important step towards the implementation of the CR and PDS. The use of SK ANTIPLAG has been mandatory for all Slovak HEIs operating under Slovak legislation since April 2010. It is an example of an unparalleled and unprecedented implementation of such a system on a national level on a worldwide scale. Educational Resources for Plagiarism Prevention. Practical Work with Examples (Trevisiol Oliver) The participants will get to know, test, and review educational resources for plagiarism prevention. Examples are: - Exercises and tasks for courses (How, with which methods and conceptual formulation can I teach students about referencing and good scientific practice?); - Reviewed educational videos (Which video may I use in class?); - Examples of myths and rumours about plagiarism (Which questions and perception do students have? How can I react to typical notions and answer frequent questions?), such as the strange rule of “you need to cite more than 3 words in a row”.

Abstract: Animals, plants and microorganisms could not exist without soil, because without it life on Earth would not be possible. Thus we should always be concerned with preserving the soil condition. This should be a personal, a municipal, as well as a national concern. Nevertheless, the role of soil is not sufficiently incorporated into the planning of sustainable development of the Savinjska statistical region, therefore more active approaches are needed in the field of soil management and protection (education, research, raising public awareness, soil protection programs, soil related educational excursions, etc.).
