MANAGEMENT OF GRADUATE STUDENT’S THESIS WRITING THROUGH A SPECIALIZED SOFTWARE SYSTEM
Full text linkThe inclusion of Learning Management Systems (LMSs) in the Bulgarian academic institutions has augmented students’ learning experience. The paper presents a software system for managing and supporting the interaction between graduate students and their supervisors in the course of theses writing. The system allows to plan, manage and track the progress of students’ theses/graduation projects. The author makes a comprehensive critical examination of the specialized software systems’ impact on the process of teaching and learning. Further studies and practical implications are also discussed
Verbal and musical choral actions in theatrical productions. Methodological and music staging aspects
Full text linkThe text is based on two realized theatre events. „Medea†by Euripidies (producer Desislava Shpatova, Plovdiv, 2020) and „Oedipus The Tiran – choruses) acting studio „Sound, Text, Melos†based on fragments from Sophocles’ tragedy (NBU, The Red House, Sofia, 2017). In the text, the author presents new approaches to the interpretation of traditional choruses in ancient Greek theater. He examines not only his own compositional techniques for creating choral episodes, but also various aspects of the preparatory rehearsal process, as well as describing some of the difficulties that theatre actors and students face in meeting such choral practices. He shares his preparatory and musicalstaging methods for the achievement of theatrical-musical unity and integrity in the choral episodes in the considered productions
Equity Ownership Strategy in Greenfield Investments : Influences of Host Country Infrastructure and MNE Resources in Emerging Markets
Full text linkThis chapter addresses equity ownership strategy in greenfield investments by multinational enterprises (MNEs) in the emerging markets (EMs). It is one of the few studies to hypothesize and analyze influences of host EM physical infrastructure in relation to investment decisions of MNEs. We use resource dependence theory (RDT) as a theoretical basis and test the moderating effects of firm resources like size and host country investment experience. Moreover, the current study assumes a more nuanced approach to studying equity ownership by analyzing wholly owned subsidiaries versus joint ventures (JVs) and including majority versus minority JVs in the analysis as well. The empirical results based on greenfield investments undertaken by Nordic (Danish, Finnish, Norwegian, and Swedish) MNEs in EMs during 1990–2015 reveals the importance of host country physical infrastructure for high equity ownership strategy. Moreover, host country investment experience moderates the effect of physical infrastructure on equity ownership strategy. Finally, the analysis of a sub-sample of greenfield JVs reveals that determinants of equity ownership strategy differ somewhat between greenfield JV or greenfield wholly owned subsidiaries (WOS).© The Author(s) 2019.fi=vertaisarvioitu|en=peerReviewed
Factor Productivity of Chosen Bulgarian Agricultural Productions
No full textТhe study focus on the Total Factor Productivity (TFP) for selected agricultural sectors (fruit growing, viticulture and dairy cattle breeding). The methodology used to determine TFP is according to Regulation (EU) 834/2014 laying down monitoring and evaluation framework for CAP 2014-2020. The Laspeyers index was applied to analyze the development of agricultural production and to explore the influence of different factors on the production output during the CAP implementation. The change was reviewed in comparison to a basis period and TFP was estimated as an index coefficient represented as industry output and the driving inputs (including labour, capital, land, variable production costs and subsidies). The study reveals a significant change in TFP indexes over the period after Bulgaria’s accession to the EU. The results show the TFP indexes decrease for fruits and cow’s milk and increase for grapes (due to improved efficiency). There is a drop in production for grapes and cow’s milk but a significant increase in production quantities for fruits. Meanwhile, the TFP index for fruit growing is slumping down, which is explicated by tangible enhancement in investment and capital costs during the covered period, which deems to improve the productivity and efficiency in the coming years. There is a need to increase and target the financial support for viticulture and dairy farming in order to hoist up the productivity and production outputs.This article is published as Toteva, D., Dimitrova, D., Stoychev, V., Factor Productiviy of Chosen Bulgarian Agricultural Prouctions.

Asset prices and exchange rates: a time dependent approach
Full text linkThis paper studies the relationship between exchange rates and asset prices. It takes the novel approach of modeling both the markets in a framework of heterogeneous agents. Investors maximize their profits from the international equity markets by solving a Mean-Variance problem. As a result, agents choose between different combinations of rules in the home and foreign equity market as well as in the foreign exchange market. Given the incomplete information setting, agents check the past profitability of their rules and switch behavior in the effort to maximize their profits. Due to the heuristics embedded within the model, this simple frame-work alone is able to create a complex, time-varying dynamics. This dynamics is analyzed for different parameters and conditions. Finally the model is brought to the data, to check the fitness of the predictions on the real world markets.Behavioral finance, exchange rates, asset prices
Foreign exchange and stock market: tow related markets?
Full text linkThis paper studies the relationship between the stock market and the exchange rate in several countries. The approach taken in the first part of this study is a linear VAR, to be compared in the following part to a MSVAR. The data is also analyzed by Granger causality tests in both contexts and a thorough description of the empirical results obtained is shown. The research uncovers a spread (but not constant over time) causality from the exchange rate and American stock market to the local markets of the different nations studied. The non-linear, time varying approach allows several considerations on the dynamics of the relationship. The markets analyzed are the Japanese, the British and the German (pre-Euro) market against the US Dollar and the US stock market. The frequency of the data used is daily.
Dry Skin - Problems and Solutions
Full text linkDry skin (Ñ…erosis cutis) is a common problem a`ecting people art di`erent age and of di`erent skin types. he reasons for dry skin can be natural (physiological), pathological, or related to the inquence of unfavourable environmental factors. he purpose of the paper is to elaborate an algorithm for diagnosis and management of patients with dry skin of various etiology. A retrospective search in the following data-bases was carried out: MEDLINE (PubMed) of the National Library of Medicine (USA), Consilium-Medicum (Russia) and Russkij meditsinskij zhurnal (Russia). When the diagnosis of dry skin is made, usually, one takes into consideration the disturbance of the hydratation of the corneal layer (10%) only. his parameter can be considered as a screening tool only and should not be the only criterion for choice of therapy. he pathophysiological changes are assocaited with disturbace of the epidermal barrier, incerase of the transepidermal water loss and pH alterations of stratum corneum. he basic diagnostic criteria are the following: transepidermal water loss and fatty secretion level (i.e., normal, low or high). hese parameters should be born in mind in the selection of treatment and can be assessed through the application of rapid real-time invivo methods such as TEWL-metry and sebumetry. he recent research achievements demonstrate that natural moisturizing factor, ceramides and aquaporins are the key factors for skin hydratation. he chouice of therapy in patienst with dry skin is a great challenge. It is strictly individualized. Treatment errors could lead to patient`s status worsening
Medical and cosmetic center or beauty salon
Full text linkProvoked by the controversy over the difference between a beautician and a medical beautician, we decided to conduct a survey using the following methods: literature, magazines, documents and anonymous surveys. The subject of our study are 100 male and female respondents aged 16 to 60 + from different locations in Bulgaria
Application of plants in cosmetics
Full text linkUndoubtedly, the cosmetic industry is one of the most widespread industries and an integral part of our daily lives. Since ancient times, and even today, the application of herbs has been gaining great popularity in medicine. Due to their healing properties herbs have a high value and are preferred by people of all ages. The purpose of this report is to find out whether people are familiar with the composition of bio-cosmetics and what their opinion about it is. For this purpose, we conducted a survey based on a set of questions people were supposed to answer. It covered 71 people aged under 18 to over 59. 66 of them were women (92.96%) and 5 were men (7.04%). The results show that 88.73% of the respondents have used bio cosmetics, and those who have not are not familiar with its constitution. Is society well-acquainted with the benefits and the practical applications of plants? Is there enough information about this type of cosmetics on the market? We will try to answer these and other closely related questions in our research
