THE PROBLEM OF DELIMITATION IN MOUNTAIN REGIONS,

It has been proved for countless number of times, including the case of Goč Mountain, that consulting geographers for various questions is obligatory. The topic of this work is the necessity of establishing borders in mountain regions and ways in which it could be performed. It also points to the fact that toponyms could create confusion. The results of the paper have led to paradox situation. By establishing  borders of the Goč Mountain, it has been proved that certain, terrains close to it, which were considered to belong to Goč, are in fact on the slopes of the other mountain, and in addition to it, between them there is one more lower mountain. Namely, it is interesting that conducting an interview among local population in southeast part of the mountain contributed to the process of confirmation of the border established by applying geographic knowledge, while on the southwest part of the Goč Mountain it was not the case. Additional analysis gave the explanation for the diversity. There is no local population in southwest part of the Goč Mountain. Interview was conducting between employees in tourist facilities, forestry workers and weekenders

Challenges and Perspectives for Development of Banking Credit Infrastructure in Russia

The purpose of this study is to demonstrate the role of modern credit infrastructure as the most important institutional component of the market of bank loans ensuring the development of credit relations, the minimization of credit risks and the creation of organizational, technological and legal environment in order to organize an effective system of bank lending. The main participants (credit bureaus, rating agencies, appraisals of borrowers of the company, banking associations, centres for market investigations, collection agencies, stock exchanges, lending agents, brokers, dealers, public institutions represented by the Bank of Russia and Federal State Statistics Service) are identified, the functional role of some of the most significant ones in Russia is defined. Preconditions for the development of the credit market infrastructure on a global scale are specified, the problem field of activity of the relevant Russian institutions is investigated. Several activities, related to the modernization and increased efficiency in their operations in Russia, are proposed. In particular, the content of reference projects on the establishment of the National Bureau of Credit Histories, the development of the national system of accreditation of credit rating agencies and the establishment of a comprehensive system of guarantee funds is updated. A conclusion about the need to strengthen the special status of the Bank of Russia as an organizer of monitoring of the credit market infrastructure and a single methodological centre is made.

Urban tourist motivations: why visit Ljubljana?

Purpose: The aim of this paper is to develop a new perspective on urban tourist motivations by applying the Analytic Hierarchy Process (AHP) model to help to understand how tourists make decisions about which destinations to visit. Method: This study was based on 30 1-hour long structured interviews with visitors to Ljubljana, the capital city of Slovenia. Respondents were asked to express their preferences between different pull-factor motives for their visit, using Saaty’s scale, and further qualitative data was collected to examine these preferences in more depth. Findings: The results of this study indicate that the most relevant criteria and thus predominant factors in motivation for visits to Ljubljana are the Cultural and Nightlife pull-factors, while Religious and Business motives are the lowest ranked factors. The paper argues that the results show the value of applying the AHP model to understand the role of pull-factors in urban tourism destination choice. Research limitations/implications: As a single-destination case study, it is important that the findings of this research are evaluated against similar studies in other cities. A limitation of this research is the fact that sub motives within major groups of pull-factor motives have not been explored in this study and this should be the subject of future, more detailed research. Originality/value: This research shows the value of applying, AHP, an under-used method to understand urban tourist motivations. The new knowledge gained through applying this method is of value to destination marketing organisations as well as to researchers conducting future studies, who will be able to replicate it and test its value

Functional Development of Principal Neurons in the Anteroventral Cochlear Nucleus Extends Beyond Hearing Onset

Sound information is transduced into graded receptor potential by cochlear hair cells and encoded as discrete action potentials of auditory nerve fibers. In the cochlear nucleus, auditory nerve fibers convey this information through morphologically distinct synaptic terminals onto bushy cells (BCs) and stellate cells (SCs) for processing of different sound features. With expanding use of transgenic mouse models, it is increasingly important to understand the in vivo functional development of these neurons in mice. We characterized the maturation of spontaneous and acoustically evoked activity in BCs and SCs by acquiring single-unit juxtacellular recordings between hearing onset (P12) and young adulthood (P30) of anesthetized CBA/J mice. In both cell types, hearing sensitivity and characteristic frequency (CF) range are mostly adult-like by P14, consistent with rapid maturation of the auditory periphery. In BCs, however, some physiological features like maximal firing rate, dynamic range, temporal response properties, recovery from post-stimulus depression, first spike latency (FSL) and encoding of sinusoid amplitude modulation undergo further maturation up to P18. In SCs, the development of excitatory responses is even more prolonged, indicated by a gradual increase in spontaneous and maximum firing rates up to P30. In the same cell type, broadly tuned acoustically evoked inhibition is immediately effective at hearing onset, covering the low- and high-frequency flanks of the excitatory response area. Together, these data suggest that maturation of auditory processing in the parallel ascending BC and SC streams engages distinct mechanisms at the first central synapses that may differently depend on the early auditory experience

Dependency Structures in Differentially Coded Cardiovascular Time Series

Objectives. This paper analyses temporal dependency in the time series recorded from aging rats, the healthy ones and those with early developed hypertension. The aim is to explore effects of age and hypertension on mutual sample relationship along the time axis. Methods. A copula method is applied to raw and to differentially coded signals. The latter ones were additionally binary encoded for a joint conditional entropy application. The signals were recorded from freely moving male Wistar rats and from spontaneous hypertensive rats, aged 3 months and 12 months. Results. The highest level of comonotonic behavior of pulse interval with respect to systolic blood pressure is observed at time lags τ=0, 3, and 4, while a strong counter-monotonic behavior occurs at time lags τ=1 and 2. Conclusion. Dynamic range of aging rats is considerably reduced in hypertensive groups. Conditional entropy of systolic blood pressure signal, compared to unconditional, shows an increased level of discrepancy, except for a time lag 1, where the equality is preserved in spite of the memory of differential coder. The antiparallel streams play an important role at single beat time lag

Synthesis, structure and spectroscopic properties of luminescent GdVO4:Dy3+ and DyVO4 particles

Part of this research was done during visit of D.J. to IFN-CNR CSMFO Lab. and FBK Photonics Unit, Povo-Trento, Italy, in the framework of the STSM (Grant No. 38223) from the project: COST Action MP 1401 Advanced Fibre Laser and Coherent Source as tools for Society, Manufacturing and Lifescience” (2014e2018).

G. acknowledges the ERDF PostDoc project No. 1.1.1.2/VIAA/1/16/215 (1.1.1.2/16/I/001).In this work, we focused on the syntheses, structure and spectroscopic properties of GdVO4:Dy3+ and DyVO4 (nano)particles of different sizes and shapes (spherical nanoparticles of 2 nm, 4 nm, and 20 nm in size, nanorods with a few nanometers in diameter and up to 10–20 nm in length and microparticles of 1–8 μm) obtained by four synthetic methods. The size effect on the structure, Raman active modes, and photoluminescence emission intensities was analyzed by X-ray diffraction, Raman and photoluminescence spectroscopy, scanning and transmission electron microscopy, and diffuse reflection spectroscopy. All X-ray diffraction patterns clearly indicated presence of a single tetragonal zircon-type phase; absence of impurity phases indicate that the dopant Dy3+ ions were successfully and uniformly incorporated into the GdVO4 host lattice due to the equal valence and similar ionic radii. Micro-Raman measurements support the XRD measurements and showed Raman-active modes of the REVO4 systems (RE = Gd, Dy). The difference between the two hosts in the diffuse reflectance spectra was observed and it could be attributed to more effective Gd3+ ions on the charge transfer bands and different polarization (compared to bulk material) in smaller nanoparticles. Photoluminescence spectroscopy showed several bands in the visible and near-infrared regions which can be exclusively attributed to the f–f transitions of Dy3+ ions.STSM (Grant No. 38223); COST Action MP 1401 (2014e2018); Ministry of Education, Science and Tech-nological Development of the Republic of Serbia (Project No: 45020 and 172056); ERDF PostDoc project No. 1.1.1.2/VIAA/1/16/215 (1.1.1.2/16/I/001); Institute of Solid State Physics, University of Latvia as the Center of Excellence has received funding from the European Union’s Horizon 2020 Framework Programme H2020-WIDESPREAD-01-2016-2017-TeamingPhase2 under grant agreement No. 739508, project CAMART
