Green product
Borut Jereb, Matjaž Knez, Darja Kukovič, Tina Cvahte, Matevž Obrecht, 2016, samostojni znanstveni sestavek ali poglavje v monografski publikaciji

Opis: According to Kotler (1998) the product is the first and most important element of the marketing combination. Product strategy should include consistent decisions "about the product combination, group of products, brands, packaging and labelling." (Kotler 1998: 459). After we identify green products we will especially be interested in specific strategies for developing green products and packaging and green brand positioning. Shortly green products can be labelled as more durable, non-toxic, made from recycled materials and have less or only necessary volume of packaging (Ottman 1997: 89). Broader definition is given by Peattie (1995) who also considers the social dimension under the concept of green. He considers the product or service as green, where its effect on the natural environment and its social impact in terms of production, use or disposal, is significantly improved with respect to conventional products and services (Peattie 1995). Green product strategy should be implemented through: - Development of green product, - Green brand, - Eco-label and - Eco-design.

Climate change adaptation
Borut Jereb, Matjaž Knez, Darja Kukovič, Tina Cvahte, Matevž Obrecht, 2016, samostojni znanstveni sestavek ali poglavje v monografski publikaciji

Opis: Since the industrial revolution, our society is driven by the increasing pace of change in business and technology. Every few decades, we are exposed to new and decisive events that bring challenges and create opportunities: think of a locomotive, electric lighting, car, airplane, television and computer. The most decisive event in the next 20 years may not come from an invention, but from the world around us - it is climate change.

Efficient open domination in graph products
Dorota Kuziak, Iztok Peterin, Ismael G. Yero, 2014, izvirni znanstveni članek

Opis: A graph ▫$G$▫ is an efficient open domination graph if there exists a subset ▫$D$▫ of ▫$V(G)$▫ for which the open neighborhoods centered in vertices of ▫$D$▫ form a partition of ▫$V(G)$▫. We completely describe efficient open domination graphs among lexicographic, strong, and disjunctive products of graphs. For the Cartesian product we give a characterization when one factor is ▫$K_2$▫.
Ključne besede: graph theory, efficient open domination, graph products, total domination

Multi-criteria and econometric evaluation of dairy products
Karmen Pažek, Jernej Turk, Sebjan Hari, Črtomir Rozman, Jernej Prišenk, 2014, izvirni znanstveni članek

Opis: This study examined the multi-criteria assessment of four dairy products: "Pomursko mlejko" (Pomurje milk), "Lejko mleko" (light milk), "Fyto mleko" (Fyto milk) and "Posneto mleko v prahu" (dried milk). The research was executed by using a multi-criteria methodology, DEX, which was complemented by an econometric analysis for light milk to estimate the trends in production and consumption before analyzed dairy products were implemented on the market. DEXi computer program results indicated that all analyzed milk products were 'above average'. The econometric model was applied to examine changes in the demand for low-fat milk (light milk). Empirical results showed significant consumer response to the increase in the prices of low-fat milk demonstrating income elasticity (1,15 unit).
Ključne besede: multi-attribute decision theory, DEXi, econometric analysis, milk products

Commercial aquaponics approaching the European market: to consumers' perceptions of aquaponics products in Europe
Vesna Miličić, Ragnheidur Thorarinsdottir, Maria Dos Santos, Maja Turnšek, 2017, izvirni znanstveni članek

Opis: The first commercial aquaponics companies are starting up in Europe. The main focus has been on solving technology issues and optimizing production. However, increasing attention is now being paid to certification and regulations linked to aquaponics, as well as the marketing of products and services. The paper presents the results of a study whose main aim was to estimate consumers’ knowledge about aquaponics and their acceptance of aquaponics products in different European regions. An on-line questionnaire was administered to the general public through the aquaponics network of Food and Agriculture COST (European Cooperation in Science and Technology) Action FA1305 “The EU Aquaponics Hub—Realising Sustainable Integrated Fish and Vegetable Production for the EU” in 16 European countries. The methodology includes univariate and multivariate statistical techniques. The results show that, on average, attitudes towards aquaponics were positive, showing no significant differences between those who already knew about aquaponics and those who only heard about it through the survey. More than 50% of respondents had never heard of aquaponics, whilst more than 70% had already heard of hydroponics. No more than 17% of respondents were willing to pay more for aquaponically produced products and no more than 40% more when compared to the price of products from conventional farming. The results confirm three different clusters of potential consumers of aquaponics products. They also suggest an urgent need for implementing integrated and holistic approaches involving all stakeholders in aquaponics, in order to define a marketing plan and efficient communication strategies. This COST action, other projects and public decision makers must invest in educating consumers about aquaponics through the organization of guided tours, thematic workshops and tastings of aquaponics products in order to raise their awareness about this new technology. It is absolutely urgent that public decision makers, in cooperation with aquaponics stakeholders, address the main institutional constraints, namely the introduction of aquaponics as an economic activity and the organic certification of aquaponics products.

Atoms and clique separators in graph products
Bijo S. Anand, Kannan Balakrishnan, Manoj Changat, Iztok Peterin, 2012, izvirni znanstveni članek

Opis: Predstavljeni so vsi minimalni klični separatorji za vse štiri standardne produkte: kartezičnega, krepkega, leksikografskega in direktnega. Maksimalne atome natančno opišemo le za prve tri prej omenjene standardne produkte. V direktnem produktu maksimalne atome opišemo le delno. Tipična situacija za standardni grafovski produkt je, da ne vsebuje kličnih separatorjev in je posledično ves produkt maksimalni atom.
Ključne besede: matematika, teorija grafov, produkt grafov, klični separator, atom, mathematics, graph theory, clique separator, atom, graph products

The edge fault-diameter of Cartesian graph bundles
Iztok Banič, Rija Erveš, Janez Žerovnik, 2009, izvirni znanstveni članek

Opis: Kartezični svežnji so posplošitev krovnih grafov in kartezičnih grafovskih produktov. Naj bo ▫$G$▫ nek s povezavami ▫$k_G$▫-povezan graf in ▫${bar{mathcal{D}}_c(G)}$▫ največji premer podgrafov grafa ▫$G$▫ dobljenih z odstranitvijo $▫c < k_G$▫ povezav. Dokazano je, da je ▫${bar{mathcal{D}}_{a+b+1}(G)} le {bar{mathcal{D}}_a(F)} le {bar{mathcal{D}}_b(B)} + 1$▫, če je ▫$G$▫ grafovski sveženj z vlaknom ▫$F$▫ in bazo ▫$B$▫, ▫$a < k_F$▫, ▫$b < k_B▫$. Dokazano je tudi, da je povezanost s povezavami grafovskega svežnja ▫$G▫$ vsaj ▫$k_F + k_B$▫.
Ključne besede: matematika, teorija grafov, kartezični grafovski produkti, kartezični grafovski svežnji, povezavni okvarni premer, mathematics, graph theory, Cartesian graph products, Cartesian graph bundles, edge-fault diameter

Distance-balanced graphs
Janja Jerebic, Sandi Klavžar, Douglas F. Rall, 2008, izvirni znanstveni članek

Opis: V članku so vpeljani razdaljno uravnoteženi grafi kot grafi, v katerih ima vsaka povezava ▫$uv$▫ naslednjo lastnost: število točk, ki so bližje ▫$u$▫ kot ▫$v$▫, je enako kot število točk, ki so bližje ▫$v$▫ kot ▫$u$▫. Dobljene so osnovne lastnosti teh grafov. Novi koncept je povezan z grafovskimi simetrijami, študirane so tudi lokalne operacije na grafih glede na razdaljno uravnoteženost. Karakterizirani so razdaljno uravnoteženi kartezični in leksikografski produkti grafov. Postavljenih je več odprtih problemov.
