Opis: Breeding and engineering of biofortified crops will benefit from a better understanding of bottlenecks controlling
micronutrient loading within the seeds. However, few studies have addressed the changes in micronutrient concentrations,
localization, and speciation occurring over time. Therefore, we studied spatial patterns of zinc and iron accumulation during grain
development in two barley lines with contrasting grain zinc concentrations. Microparticle-induced-X-ray emission and laser ablationinductively
coupled plasma mass spectrometry were used to determine tissue-specific accumulation of zinc, iron, phosphorus, and
sulfur. Differences in zinc accumulation between the lines were most evident in the endosperm and aleurone. A gradual decrease in
zinc concentrations from the aleurone to the underlying endosperm was observed, while iron and phosphorus concentrations
decreased sharply. Iron co-localized with phosphorus in the aleurone, whereas zinc co-localized with sulfur in the sub-aleurone. We
hypothesize that differences in grain zinc are largely explained by the endosperm storage capacity. Engineering attempts should be

Opis: The findings so far of the Pierre Auger Observatory and those
of the Telescope Array define some requirements for a possible
next generation global cosmic ray observatory: it needs to be
considerably increased in size, it needs enhanced sensitivity
to composition, and it has to cover the full sky. At the Pierre
Auger Observatory, AugerNext aims to conduct some innovative
initial research studies on a design of a sophisticated hybrid
detector fulfilling these demands. Within a European supported
ASPERA/APPEC (Astroparticle Physics European Consortium)
project for the years 2011-2014, such R&D studies primarily
focused on the following areas: i) consolidation of the
detection of cosmic rays using MHz radio antennas; ii) proof-
of-principle of cosmic ray microwave detection; iii) test of
the large-scale application of new generation photo sensors;
iv) generalization of data communication techniques; and v)
development of new schemes for muon detection with surface
arrays. The AugerNext Consortium consists of 14 principal
investigators from 9 countries. This contribution summarizes
some achievements of the R&D studies within the AugerNext

Brand introduction on the Slovenian market: case study Gurieli teaMariam Parekhelashvili
, 2016, magistrsko delo
Opis: Human beings have always tried to create new, innovative things so as to gain profit out of them. Companies which are following the human beings nature strive to satisfy customers’ demand for high-quality products and services. Developing a new product is always a complex and experimental process. The process of introducing new products to an international market is as risky as it is vital for the long-term success of many companies. The number of new products introduced globally is increasing every year, but great majority of them fail.
The main purpose of this thesis is to develop an effective marketing plan for the new product introduction to an international market - a successful launch of the Georgian Gurieli tea to the Slovenian market. Market research gave us a business view of the tea industry on the Slovenian market. By means of secondary research and market analysis, we identified potential customers, understood market conditions and competitive landscape. The main steps of proposed marketing strategy are segmentation, targeting and successful positioning (STP). STP focuses on commercial effectiveness, selecting the most valuable segments of the Slovenian market and developing the marketing mix and product positioning strategy for each recognized segment. Planned implementation of a subtle advertising campaign for the Gurieli tea would be a vital component of the strategy - through an innovative marketing communication mix the product would be successfully introduced and promoted to target customers.

ASSESSMENT OF THE DEVELOPMENT POTENTIAL OF FOREST-WOOD PROCESSING CHAINSlavica Ilc
, 2016, magistrsko delo
Opis: Slovenia is the third most forested country in Europe. Nevertheless, in the last twenty five years this natural wealth did not get the adequate role in national development strategies, which unnecessary reduced their sustainability potential and lead the Slovenian forest-wood industry in a very bad situation. The forest-based sector in Europe is in a period of profound structural changes, which requires reassessment of the wood-chain products outlook.
In the master’s thesis, the importance of integration of forestry and wood industry has been evaluated with the meaningful connection of different analytical methods: material flow analysis (MFA), SWOT analysis and life cycle assessment (LCA). With comparison of the roundwood and sawnwood material flow in Slovenia, Italy and Austria, the critical points in the Slovenian forest-wood chain were identified. In contrast to Austria and Italy, where wood is intensively reworked, Slovenia exports large amounts of untreated roundwood. As a consequence, the gross value added (GVA) per employee of wood sector in Slovenia reaches only 40 % of GVA in Austria and 50 % of GVA in Italy. Not only MFA, but also the SWOT and LCA analyses show, that wood processing into finished products is important both in terms of the value added and the environmental impact, as well as for more decisive shift of the economy towards a low-carbon society.
Slovenian economy could take advantage of its sustainable development potential to a great extent by increasing the level of raw material self-sufficiency and energy independency. It is essential to re-establish forest-wood processing chain, to rework wood at home into products with the highest added value, and to use wood residues as renewable feedstock in green chemistry industry and for transformation into energy with novel technologies. Slovenian vision of sustainable economy has great potential, but requires enhanced cross-sectoral integration of forestry, wood processing, construction, chemistry and energy.

Development of Slovenian linguistic terminology in Slovenian grammars in the 18th and 19th centuriesMitja Trojar
, 2017, doktorska disertacija
Opis: The dissertation describes the problems of metalanguage and peculiarities of linguistic terminology. Special attention is paid to autonymy, which plays a central role in metalanguage.
The dissertation presents the life and work of Eugen Wüster, the founder of traditional terminology, and the principal tenets of his approach to terminology. Traditional terminology is critically evaluated; we show its inability to describe linguistic terminology: it lacks a coherent theoretical apparatus enabling description, its semantic theory is based on classical definition, which in many cases cannot be formulated, which means that traditional terminology is also unable to account for translation of terms and comparison of concepts across different concept systems.
A sample of 50 basic linguistic terms from 19 grammars from the 18th, 19th and 20th centuries was used to examine the development of Slovenian linguistic terminology and to ascertain who played the most important role in it. The research shows that Anton Janežič made by far the most important contribution to Slovenian linguistic terminology: he introduced 27 terms (in both his 1854 and 1863 grammars), which represents 54% of the 50 terms retained by Breznik.
The dissertation also contains some remarks on the semantics of linguistic terms.
The scientific relevance of the thesis lies in its critical evaluation of traditional terminology; the results show that traditional terminology faces a number of theoretical problems; a new theory of terminology is needed, one that will be able to account for translation of terms as well as for diachronic conceptual change. The scientific relevance of results related to the second research goal (determining the contributions of individual grammarians to the development of Slovenian linguistic terminology) consists in proposing a model of research that could be used in order to measure the influence of a specific author on the introduction of new terms.

ACCESSIBILITY AS A NON-PREJUDICIAL APPROACH: IS CULTURE BACK TO NORMALITY?Ilaria Bollati
, 2018, doktorska disertacija
Opis: This research explores the general and actual accessibility to cultural spaces and organizations, focusing on the network of relationships between contents, innovation, and participation. It investigates how Culture can be perceived as a normal experience, actually able to set a rich dialogue with each of us, normal ordinary people/consumers. Normality means inclusion and sharing. The proposed investigation is based on a triad of interactions among culture, economics, and design.
Assuming that Culture generates its value from a cognitive approach, or from a dynamic and context-dependent value chain that is subject to a cognitive evolution, this research acknowledges that the cultural experience is subject to a double issue of access:
- The horizontal question is related to complications associated with the structure. Believing that ‘culture is special’ implies the risk of progressively widening the gap between cultural supply and society. Culture is ‘locked’ in specific sites and a big slice of the world’s adult population has yet to be involved in any cultural experience.
- Once physically inside the cultural structure, the vertical issue is generated by the difficulty in entering in contact with the offered contents. This research focuses only on museums and multimedia exhibitions in which the learning process has changed: the research presents itself as a conversation where both ‘those who know’ and ‘those who learn’ play equally active parts in a relative process of understanding.
Starting from the existing processes, forms, previous studies and case studies, the survey yearns for their systematization in innovative models. The process, from theory to practice and vice versa, goes beyond a traditional mechanism of deduction: it moves from specific contexts to the abstraction of replicable approaches.
The question of how the narration emerges guides you toward a new method of analysis, study, and cataloguing; a schematization capable of investigating not only knowledge, but also the visitor's ‘cognitive metabolism’ (how knowledge is acquired) during the multimedia experience; an innovative multipurpose tool, useful for both the museum institution and the designer.
The research finally assesses and takes into account an actual experiment, the outcomes of which may prove to be useful in feeding theoretical implications with empirical experiences: RovelloDue - Piccolo Spazio Politecnico, a temporary multimedia space.

Quality Assured Across Borders of Disciplines and CulturesPeter Purg
, 2019, objavljeni povzetek znanstvenega prispevka na konferenci
Opis: Abstract (full):
Within the international master study programme of Media Arts and Practices (MAP) the University of Nova Gorica School of Arts is currently developing an interdisciplinary module in Art, Science and Technology (MAST) within a diverse partnership of two further universities and three NGOs. Both curriculum development projects were funded by the European Commission for their progressive, even disruptive character. If MAP (2011-2014), developed within the ADRIART.net project, was to join four countries as well as several artistic and media production fields creating a new partnership model and a contemporary employment profile, MAST (2018-2020) now seeks to root the art-thinking paradigm deep into the innovation process outside university. In order to reinvent better and meaningful futures for the society at large the dominance of the technological and the scientific approach is to be balanced out by the artistic openness and radical difference. This in turn mirrors the structure of the MAST curriculum – not only that its outcomes are unprecedented and tuned onto most progressive priorities of the Europen Union. The syllabus reminds of the innovation process itself, building a new module-specific graduate profile of an “innovation catalyst’.
The abovementioned two cases will be interpreted on the background of ‘The Standards and Guidelines for Quality Assurance in the European Higher Education Area’ (ESG) as the primary setting of their development and implementation, while the ‘internal’ quality aspect shall be prioritized. The discussion will predominantly refer to the design and approval of programmes, but also present some novel solutions in student-centered learning, teaching and assessment. After touching upon a relevant recognition issue, the public impact and meaning of such programmes will be considered more broadly.
As far as the design and approval of programmes (ESG 1.2) are concerned, the Guidelines point out that curricula should be designed „in line with the institutional strategy“ which often proves a paradox – a new academic programme development may instigate radical institutional change from the bottom-up, such that is unlikely to occur through the conventional top-down approach. The MAP project involved four university partners, of which two accredited the master programme fully as such (Croatia and Slovenia) and two participated therein merely with partnership modules. While the Slovenian partner gradually modified its strategic priorities as a (fairly small) art school throughout the project's three years, the bigger Croatian national art academy would let the MAP programme remain insulated from other programmes, preventing the curricular innovations and new teaching and learning methods from spreading to other programmes. This eventually led to inter-institutional conflicts and a closure of the programme in 2018 after three years of its running. Even if all invlved universities „involved students and other stakeholders in the work“ and the MAP programme contained „well-structured placement opportunities“ (ESG 1.2), its sustainability was evaluated low also in the case of the Italian and Austrian partners, since most of the MAP curricular structures eventually proved too open and progressive for their traditional acdemic environments. The Graz Technical University (Austria) returned in the MAST project again to enter a new, more contemporary alliance, founded on their bilateral continuity with the University of Nova Gorica, and their strategic priority of developing interdisiplinary programmes. The latter has in 2014 also established and continues to lead a South-Eastern-Europe wide CEEPUS network of ten art academies named ADRIART.CE (Belgrade, Budapest, Graz, Nova Gorica, Krakow, Rijeka, Split, Sarajevo, Belgrade, Skopje, Sofia), three of which presented its core that developed from the MAP partnership (www.ADRIART.net/ce). Besides Nova Gorica and Graz, the MAST partnership involves one further university (Madeira University, Portugal) and three NGOs (the renowned Kapelica Gallery from Slovenia, the Croatian Cultural Allience and the Europe-wide network Culture Action Europe).
The ESG standard 1.3 on student-centred learning, teaching and assessment suggests that the programme delivery should „encourage students to take an active role in creating the learning process, and that the assessment of students reflects this approach.“ The MAP programme manifests this approach in several novums such as the 'Progress Track' module, where students critically peer-reflect on their academic progress along three semesters, or the 'Studio' module that brings into the programme external art (and later in MAST also science and/or technology) practitioners. It also treats contemporary topical issues that relate to the European topics such as e.g. 'The Future of Work' as well as to the profile of the cohort, their course selections and career orientation. A continuous 'Carrier Module' (MAST being one of them, others are Film, Animation, New Media, Photography and Contemporary Art Practice) in the MAP programme supports the student's „flexible learning path“ along three semesters of gradual academic progression: After exploring the chosen realm, and then defining own topical interest and method, the student focuses on her or his area of artistic (or interdisciplinary) investigation, in order to complete the Master Thesis (that includes a theoretical thesis and a practical project) in the fourth semester, all to encourage „a sense of autonomy in the learner, while ensuring adequate guidance and support from the teacher“. In the case of MAST the students shall each year be faced with the semester-long 'Challenge' course that is to keep them deeply involved in a real-life innovation process brought in from NGOs or companies, along with their expert mentors, or evaluators (in assessment committees, programme boards etc).
Both MAP and MAST curriculum development projects focussed importantly on the issue of „fair recognition of higher education qualifications, periods of study and prior learning, including the recognition of non-formal and informal learning“ (ESG 1.4). This was to not only support but also promote mobility of staff and especially students, since both curricular structures instigate international as well as inter-sectoral collaboration: if the academic experience of students and their career prospects is to be advanced, a dynamc flux and interaction of students, (external) mentors and (university) teachers needs to be preserved at both entry and exit points to the programme (or module). Only this way the positive public impact and meaning of such programmes (ESG 1.8) can be kept transparent – not only to be accounted for, but also actively steered towards actual social and economic relevance! Study programmes that matter to all stakeholders – the students, the universities and the employers, including a broader public, need to be kept open for manifold talents and apply progressive interdisciplinary teaching and learning methods, attracting experts and tackling real-life challenges across disciplinary sectors, and national borders.
