1. Families of association schemes on triples from two-transitive groupsJose Maria P. Balmaceda, Dom Vito A. Briones, 2025, original scientific article Abstract: Association schemes on triples (ASTs) are ternary analogues of classical association schemes. Similar to how Schurian association schemes arise from transitive groups, ASTs arise from two-transitive groups. In this paper, we obtain the third valencies and the number of relations of the ASTs obtained from two-transitive permutation groups. Further, we obtain the intersection numbers of the ASTs produced by PΓL(k, n), PSL(2, n), AΓL(k, n), and the sporadic two-transitive groups. In particular, the ASTs from the actions of PΓL(k, n), PSL(2, n), and the sporadic groups are commutative.
Keywords: association scheme on triples, permutation group, ternary algebra, algebraic combinatorics

2. Exploring the drivers of farm sustained participation in agri‑environmental programmesŠtefan Bojnec, Imre Fertő, 2025, original scientific article Abstract: This paper examines the socioeconomic and institutional determinants influencing sustained participation in Agri-Environmental Climate Schemes (AECS), drawing on comprehensive panel data from Slovenian farms covering the period 2014–2021. Using discrete-time hazard models and nonparametric duration analysis, we identify economic resilience—characterised by larger farm size, income diversification, and prior participation—as a significant driver of prolonged AECS engagement. Conversely, greater dependence on market-based income is negatively correlated with long-term participation, highlighting inherent trade-offs between short-term economic gains and sustained ecological commitments. Additionally, educational attainment exhibits a modest yet positive association, emphasising the importance of knowledge dissemination and capacity building in facilitating the responsible use and sustained environmental protection. Our findings underscore the necessity for context-specific policy designs, advocating diversified financial incentives, robust extension services, and market-aligned strategies to effectively integrate agricultural productivity with environmental sustainability.

4. Activities for promotion of local food and protected agricultural products in Slovenia : working paperPatricia Blatnik, Štefan Bojnec, 2015, other monographs and other completed works Abstract: Activities for promotion of Local Slovenian food have been carried out through several national projects. One of the most prominent ones is the project Traditional Slovenian breakfast. Other projects include advertising campaigns (We Are Connected with delicacies from our countryside, Fresh food from your vicinity, Be aware of local origin), school schemes (School fruit scheme, School milk scheme), events (Goodness of farms in Ptuj, The countryside in the city), website promotion (Buy local), and brand establishment (Buy Slovenian). For protection of agricultural products and foodstuffs there are 3 European quality schemes: Protected designation of origin, Protected geographical indication, and Traditional speciality guaranteed. Besides the three European schemes in Slovenia there is also another scheme for protection, Designation of higher quality. In Slovenia are 5 protected milk products, all of them cheeses. Under the quality scheme Protected designation of origin are included: Mohant cheese, Nanos cheese, Tolminc cheese, and Bovec cheese, Under the quality scheme Higher quality is included: Semi-hard cheese without preservatives - semihard cheeses of Zelena dolina.

5. The equalization scheme of the residual voluntary health insurance in SloveniaBoris Zgrablić, 2015, original scientific article Abstract: Residual voluntary health insurance in Slovenia covers the difference between the (recognised) value of the health service and the part of this value that is payed by the compulsory health insurance. From the inception of compulsory health insurance in 1992, residual voluntary health insurance has open enrolment. From 2006 community rating applied, as well as an equalization scheme with which the differences in health services expenses, arising from the different structures of the insurees of the single insurance undertakings regarding age and gender, shall be equalized. The equalization scheme of the residual voluntary health insurance in Slovenia is presented, along with a detailed explanation of the formulae required for the computation.

6. Evaluation of measurement uncertainty for the methods of analysis used to assess the characteristics of olive oil and olive-pomace oil from commission regulations EEC 2568/91 and EC 1989/2003 : a case sample evaluating the measurement uncertainty for peroxide valueBojan Butinar, Milena Bučar-Miklavčič, Erika Bešter, Vasilij Valenčič, 2007, original scientific article Abstract: Metrology has been present in our scientific knowledge for a long time, but mostly in physical measurements. Chemical measurement can be defined as a comparison of a quantity of measurand and relating it to a unit (e.g. mol/kg).When expressing a result of a measurement, the problem of traceability, validation and the measurement uncertainty (MU) evaluation must be challenged. It is well known that MU is a parameter associated with the result of a measurement that characterizes the dispersion of the values that could reasonably be attributed to the measurand. The EEC document 2568/91 with its annexes gives the methods of analysis to assess the characteristics of olive oils and olive-pomace oils with given limits. The EC document 1989/2003 gives the scheme, the algorithm, the pathway, the decision tree to differentiate between various types of olive oils using the particular determinations based on limits. The major lack of these EC methods is the non-existence of validation parameters, which are crucial in determining the MU (and in accreditation of a laboratory). There are several ways of evaluating (better term than calculating) the MU: with model equation, with use of a certified reference material (CRM) and with participation in a proficiency testing (PT) scheme. MU for a method of analysis is inherent to a laboratory and can serve as a tool for 'measuring' the quality of a laboratory. Unfortunately, there are practically no CRM's in the olive oil testing field. The only way to achieve a usable MU is through participation in PT schemes.
