Higher growth through the Blue Ocean Strategy: Implications for economic policy

Higher growth is a key goal of companies, governments, and societies. Economic policies often attempt to attain this goal by targeting companies of certain sizes that operate in specific industries and focus on a specific business activity. This approach to policy making has considerable shortcomings and seems to be less than fully effective in increasing economic growth. We suggest a new approach to policy making that stems directly from the entrepreneurial perspective. This approach examines a successful business strategy framework - the Blue Ocean Strategy - to discover conditions for high growth. We test the propositions on empirical data for two cases of successful high-growth business, namely Slovenian gazelles and Amazon.com. The results reveal a gap between the macro level of economic policy making to achieve higher growth and the micro level of business growth. The findings call for a change in the focus of economic policies on specific size companies, industries, and business activities to intraindustry cooperation, collaboration between companies of different sizes, value innovation, and creation of uncontested markets.     

Market orientation in managing relationships with multiple constituencies of Croatian higher education

In this paper, market orientation in Croatian higher education (HE) is discussed within the context of stakeholder-oriented management. Drawing on existing studies, the ‘classical’ empirical model, describing the market orientation of generic nonprofit organisations, has been adapted to the contingencies of the Croatian HE sector. Empirical testing of the model, based on primary data drawn from the majority of public institutions of higher learning in the country, reveals inadequate market orientation toward the relevant stakeholders. Although social market orientation currently does not exist in Croatian HE institutions, the empirical results confirm that it might be possible to initiate a ‘virtuous circle’, in which relevant market orientation and stakeholder management practices, directed toward one or other of the stakeholders, simultaneously enhance orientation toward the other stakeholders. Unfortunately, the current situation in HE is not satisfactory, which could hinder the implementation of development of knowledge society in Croatia.

X-ray radiography and tomography for monitoring the penetration depth of consolidants in Opuka – the building stone of Prague monuments

Stone consolidation is one of the major restoration treatments used for historical monuments preservation. A natural stone is a complicated heterogeneous porous system making the process of consolidation dependent on many variables. In practical restoration aims, for a given stone type, the selection of a suitable consolidant and consolidation conditions therefore remains a complex issue. The impregnation depth is a key factor for the assessment of the treatment efficiency. The combination of state-of-the-art hybrid pixel semiconductor detectors with newly available micro-focus X-ray sources makes possible to apply X-ray radiography, an ideal non-destructive tool, for penetration depth monitoring. In this study, high-resolution X-ray radiography is used for monitoring the penetration depth of organosilicon consolidants in the Opuka stone. The penetration depth has been evaluated in relation to the time of consolidation, stone porosity and consolidation mixtures properties. The exact influence of the X-ray contrast agent on the consolidation depth has been investigated as well. The information obtained provides supplementary knowledge on the suitability of investigated products for the treatment of this type of stone. In our study, the capabilities of X-ray radiography have been demonstrated on X-ray radiography simple projections, high-resolution computed tomography (CT) as well as on the dynamic processes monitoring. The results thus can serve also as an instrumental and methodological example applicable for consolidation monitoring of other stone types.

Measurement of fluid flow generated by artificial cilia

We observed and measured the fluid flow that was generated by an artificial cilium. The cilium was composed of superparamagnetic microspheres, in which magnetic dipole moments were induced by an external magnetic field. The interaction between the dipole moments resulted in formation of long chains-cilia, and the same external magnetic field was also used to drive the cilia in a periodic manner. Asymmetric periodic motion of the cilium resulted in generation of fluid flow and net pumping of the surrounding fluid. The flow and pumping performance were closely monitored by introducing small fluorescent tracer particles into the system. By detecting their motion, the fluid flow around an individual cilium was mapped and the flow velocities measured. We confirm that symmetric periodic beating of one cilium results in vortical motion only, whereas asymmetry is required for additional translational motion. We determine the effect of asymmetry on the pumping performance of a cilium, verify the theoretically predicted optimal pumping conditions, and determine the fluid behaviour around a linear array of three neighbouring cilia. In this case, the contributions of neighbouring cilia enhance the maximal flow velocity compared with a single cilium and contribute to a more uniform translational flow above the surface.     

Natural polymers as alternative consolidants for the preservation of waterlogged archaeological wood

In recent years, there has been increased interest in examining alternative polymers for the conservation of archaeological artefacts, particularly waterlogged timbers, providing better, renewable, greener alternatives to poly(ethylene glycol) (PEG). The degradation of PEG consolidants in the timbers of the sixteenth century warship Mary Rose has been examined and the rheological and thermal properties of PEG have been compared with its monomethyl and dimethyl ethers and several polysaccharide consolidants (chitosan, guar, and 2-hydroxyethyl cellulose) in order to evaluate their potential as alternative consolidants for the conservation of waterlogged wooden artefacts. Additionally, the effect of the polymers on the archaeological wood was characterised by thermogravimetric analysis and solid-state nuclear magnetic resonance spectroscopy. The results suggest that the future of conservation technologies lies with polysaccharide consolidant materials, which show enhanced compatibility with wooden artefacts with no detectable side effects while also being cheap, with extremely low toxicity, renewable, and sustainably resourced.     

External and internal assessment in the final examination in secondary schools in Slovenia

This article examines the introduction of the final examination as an external national system of assessment of students in the transition from secondary school to university education. Since 1991 Slovenia has followed foreign models, the British one in particular; however, it has also considered its own traditional system of education. Students take the final examination (the matura) in three compulsory and two elective subjects; of which sociology can be one. A case study considering this subject demonstrates how external assessment can be fine tuned using internally supervised and assessed project work, in which seminar essays are produced. This article conducts a qualitative and quantitative analysis of the essays and structured questions forming the written examination; the same procedure is applied in the case of seminar essays. Also included are the opinions and experiences of students regarding their preparations for the final examination and their work in the seminars; the students’ feedback is decidedly positive. So far, the external and the internal results have shown little correlation, a fact that points to certain problems in the final examination assessment system. The positive results in sociology, considered in this contribution, suggest that it would be worthwhile applying similar assessment strategies in other subjects. It is, however, impossible to provide a straightforward answer to the question of a positive impact of the final examination on the desired improvement in the quality of the education process.     

University stakeholders,intergenerational relationships and lifelong learning: a European case study

ABSTRACT

This study describes and analyzes the role of a Senior Programme of the University of Lleida (Catalonia, Spain) aimed at fostering older people’s lifelong learning, active ageing, social participation, and intergenerational relationships. Based on qualitative Action Research and Participant Observation, this article examines the participation of senior students as stakeholders in this Programme and in two European projects, SIforAGE and TOY, developed between 2012 and 2017. The findings reveal the importance of these learning and research activities to promote intergenerational solidarity, the quality of life of older people, and the development and improvement of the Senior Programme itself.
