Authors: Pavlovaitė Ugnė , Griesienė Ingrida
Published: December 2019

The article conceptualizes the audience of art organization, introduces the main art organization audience’s groups and analyzes the concept of relationship marketing in the context of art organizations. Relationship marketing tools are identified as an important instrumentality in order to develop and maintain networks between interested parties (various audience groups). The art industry is perceived as a medium for the implementation of relationship marketing. The theoretical platform model that is developed by art industry organizations is revealed as a universal and widely applicable tool among the biennials of contemporary art. The analysis of academic discourse presents the key groups of relationship marketing as well as dimensions which allows to evaluate the success of maintained networks. Following the features of public sector institutions a noticeable aspect in building relationships is the pursuit of economical benefit. Despite the economical benefits, interested audience groups of art organization are seeking of social benefits. At this point, the main relationship marketing dimensions – trust, commitment, satisfaction – are considered as a valuable measurement of the created platform network that reveals quality. It is concluded that arts organizations use appropriate relationship marketing tools to identify, establish, and maintain long-term relationships with their audience, for which the arts organizations provide additional organizational resources related to communication. The article presents an empirical study of the marketing relations of the biennial from research conducted in 2019 about the development of the biennial of contemporary art as an art platform where relationship marketing, as well as the main art organization audience groups, were presented. Case studies of the biennials of the contemporary art biennales Kaunas Biennial and EVA International were carried out. A qualitative study was chosen in order to empirically test the functioning of the theoretical model of the biennial as an art platform in terms of relationship marketing. Research data were collected using a qualitative (structured-standardized interview) research method. Following the analysis of the scientific literature and the empirical research data, guidelines for the development of an art organizations in terms of audience development were created.
Lithuanian Social Entrepreneurs’ Experiences of Evaluating the Impact of Their Social Businesses
Authors: Pušinaitė-Gelgotė Rasa , Pučėtaitė Raminta , Novelskaitė Aurelija
Published: December 2019

This paper raises research questions on how social business representatives assess the impact of their social businesses and what methods they use to evaluate or measure it. The findings of data analysis of the interviews with 20 social entrepreneurs in Lithuania indicate that social entrepreneurs just begin to measure impact and do not always distinguish it from outcomes and outputs. This can also be influenced by impact measurement methods/tools, which are publicly available for social entrepreneurs or provided by funding organizations. Social entrepreneurs acknowledge that they must create and evaluate this impact, but research findings indicate that they distinguish more reasons not to do that. Impact evaluation is more explicitly revealed when discussing internal (consumers, employees) rather than external stakeholders. Some social entrepreneurs understand the need to evaluate their activities in monetary terms, but they do not do it, which is explained by the early development stage of social businesses in Lithuania. Moreover, social entrepreneurs do not have experience in measuring impact from a multidimensional perspective, i.e., including the social, environmental, cultural, and economic dimensions, and it seems that the necessity of doing this has not come to their awareness yet. The article is concluded with recommendations for strengthening social entrepreneurs’ capabilities in impact evaluation.
Bilingual Access of Single and Paired Words in the Context of Episodic Memory
Authors: Norvilas Algis
Published: December 2019

In a series of four experiments, the cued-recall task was used to explore bilingual word representation in episodic memory. When target words were encoded singly, their recall to same-language and to crossed-language extralist cues was found not to be different. These results appear to support a language independent view of bilingual word representation in which words of different languages are mutually accessible. When target words were encoded in a cue-target relational fashion, recall of target words was much higher to original-language than to translated-language intralist cues, thus supporting a language dependent view. In this case information seems to be bound by the language in which it was originally encountered. This difference in results of cross-language cuing of singly and relationally encoded words was assumed to result from shifts in meaning brought about by contrasting word experiences. More broadly, the findings were interpreted within the context of Don Dulany’s (1997) mentalistic theory of evocative versus deliberative processing of words.

Authors: Rahmawati Yenni
Published: December 2019

ABSTRACTThe Indonesian ELT current curriculum (the 2013 Curriculum) adopts communicative Approach (CA) as its basis foundation. Despite the fact that this approach has been adopted for some years, some research studies showed that it does not bring any significant improvement to the learner’s outcome. There are several reasons underpinning the failures of the implementation of CA in regards to the 2013 curriculum. This study is, therefore, aimed at investigating the EFL Indonesian teachers’ perspectives on the challenges they faced in the implementation of communicative approach in their classrooms along with the 2013 curriculum. Four participants were involved in this study that were given questionnaires and interviewed for data collection. Qualitative design by case study was used in this study and the results indicated that all teachers in this study encountered challenges when implementing the concept of CA along with the 2013 curriculum, i.e. students’ low motivations, the teachers’ role, the class size, the teachers’ income, and the availability of English materials.ABSTRAKKurikulum Bahasa Inggrisdi Indonesia saat ini (Kurikulum 2013) mengadopsi Pendekatan Komunikatif (CA) sebagai landasan dasarnya. Terlepas dari kenyataan bahwa pendekatan ini telah diadopsi selama beberapa tahun, beberapa penelitian menunjukkan bahwa Pendekatan Komunikatif tidak membawa dampak yang signifikan terhadap hasil pelajar. Ada beberapa alasan yang mendasari kegagalan implementasi CA tersebut terkait kurikulum 2013. Oleh karena itu, penelitian ini bertujuan mengeksplorasi perspektif guru bahasa Inggris di Indonesia tentang tantangan yang mereka hadapi dalam menerapkan pendekatan komunikatif di ruang kelas mereka dalam kerangka kurikulum 2013. Empat peserta terlibat dalam penelitian ini yang diberi kuesioner dan diwawancarai untuk pengumpulan data. Penelitian ini menggunakan desain kualitatif dengan studi kasus dan hasilnya menunjukkan bahwa semua guru dalam penelitian ini menghadapi tantangan ketika menerapkan konsep CA bersama dengan kurikulum 2013, yaitu motivasi siswa, peran guru, 'konten asing' , dan ketersediaan materi bahasa Inggris.

The parameters of pH and water activity of the extracts of chopped meat as well as water-binding capacity, water molecular mobility state and penetration degree of chopped meat are investigated. The mass losses of meat chopped semi-finished products during heat treatment are investigated. The analysis of the organoleptical parameters of the quality of meat chopped products from beef and ostrich meat is carried out. It was established that ostrich meat differs by 6.4% higher indicator of active acidity, while the difference between the water activity of ostrich meat and beef is insignificant. According to the results of the research, it is established that owing to the higher content of proteins, the ostrich meat has a higher by 5.7% index of water-binding capacity and a higher by 10.8% degree of penetration. Based on the analysis of the results of the study of the state of water molecular mobility in the investigated types of raw materials, the presence of a greater amount of bound water in ostrich meat in comparison to beef is confirmed. The inverse-proportional relationship between the parameters of the yield value and the water-binding capacity of the investigated samples of meat raw material, as well as a strong correlation between them, is revealed. It was established that mass losses during the heat treatment of semi-finished chopped ostrich meat products are almost 20% lower than those made from the beef. The results of laboratory testing of the recipes of chopped beefsteaks  from ostrich meat and beef in different proportions are given. According to the results of the evaluation of the quality of the chopped beefsteaks by the organoleptical indicators, the using of the ostrich meat in a combination with beef at a ratio of 1:1 for chopped beefsteaks production is proposed.

The article presents the results of indication of water and surface contamination. The researches were aimed at estimation of water safety and sanitary-hygienic condition of surfaces. To study the contamination of water samples and common surfaces, we used the traditional method and the bioluminescence-based express method. The bioluminescence method is based on determining the total amount of ATP (bacterial, somatic and extracellular) on contact surfaces and in water. The level of ATP (adenosine triphosphate) was determined using the Lumitester PD-30 (Kikkoman, Japan) luminometer device according to the manufacturer's instructions, using special test systems. The ATP bioluminescence method is commercially more available for simple and quick monitoring of the sanitary-hygienic control effectiveness according to the HACCP principles or international requirements. The traditional method of determining water (and other material) contamination was performed by inoculating water or surface wiping on a common nutrient medium and further cultivation under appropriate conditions. The strongest glowing reaction was observed in sea water, which can be explained by the presence of organic substances in it, while the bioluminescence values in potable (bottled) and filtered water tests were most close to control test. The results of testing the sanitary-hygienic condition of surfaces showed that the amount of adenosine triphosphate exceeded the limits in almost all tested objects. However, a slight exceeding of adenosine triphosphate level was observed on the internal surface of new (plastic) food containers. The investigations performed show that the bioluminescence-based express method can be used as a primary control that gives immediate information about the contamination of both surfaces and liquids. Using the bioluminescence method can shorten the time of the study and therefore reduce the cost of the test. However, when determination of qualitative and quantitative composition of the tested object’s microbiota is necessary, then the classical microbiological control must be performed.

Alternate changing of the steaming periods and liquid overflow allows to intensify mass transfer between liquid and steam and to reduce the specific consumption of heating steam in the process of separation of multicomponent mixtures. Known methods and models have not found widespread practical use due to the lack of mass transfer in the steam period, fluctuations in steam pressure in the collector, the complexity of constructive solutions to ensure cyclic mode, etc. The authors propose a technology for rectification, which involves the cyclic motion of the liquid without interrupting of the supply of heating steam and the construction of a rectification column for its implementation. The purpose of the work was to research the effectiveness of the proposed technology in the process of rectification of alcohol-containing fractions and to establish the specific flow rate of steam in the impurity concentration column. To ensure a cyclic mode, the column was equipped with movable liquid transfer devices connected to actuating mechanismes, which acted according to the controller program, and perforated (scale-shaped) trays. The primary task was to determine the hydrodynamic mode of operation of the contact devices - the lower and upper the critical vapor velocity of at which the liquid is retained on the plates and there is its entrainment. It is established that the vapor velocity in the free section of the column can reach 1.2 m/s or more, and in the openings of the scales must exceed the first critical velocity of 6.5-7.5 m/s. The weeping of the tray occurs at the vapor velocity in the holes of 1.5-1 m/s. The investigations were carried out in the production conditions of the Chudniv branch of SE “Zhytomyr liquor producer ”. It is experimentally proved that in the process of rectification of alcohol-containing fractions, the main impurities are removed completely, the degree of extraction of higher fusel alcohols is increased by 38%, methanol - by 15.6 %, the multiplicity of concentration of the main impurities is increased by 25 %, the higher alcohols - by 40 %, methanol – by 34 %, acrolein – by 36 %. The costs of heating steam are reduced by 30 % compared to typical installations and do not exceed 13 kg/dal of absolute alcohol introduced with feed. Exempted from the key impurities the bottom liquid of the impurity concentration column should be used for hydroselection in the purifying column.

The paper reviews the literature on the existing technologies of medium dry and semi-sweet table wines. The main problems of manufacturing this type of wines have been outlined, as well as how they are solved by domestic and foreign winemakers. The classical scheme of producing medium dry and semi-sweet wines allows retaining the aroma of a certain grape variety and obtaining quality wines, but it is not applied in Ukraine as it is technologically complicated and costly. The scheme that involves blending is far more economical, but does not allow retaining all the fine aromatic nuances of a variety. So, the article considers the ways of obtaining medium dry and semi-sweet wines using grape must that has been concentrated by freezing. It has been shown that this technology will allow retaining the valuable substances of the variety aroma and will be the basis for producing the highest-quality wines of this type. For the research, the following samples have been analysed: clarified must of the Rkatsiteli and Citronny Magaracha grape varieties, must concentrated by freezing, vacuum must, dry wine materials, and the medium dry white table wines made from them. In the musts and wines, the main physical and chemical characteristics have been studied (the mass concentrations of sugar, titrated acids, total and free sulphur dioxide), as well as some additional parameters (the pH, mass concentrations of phenolic substances, free and bound terpene alcohols, optical density with the wavelength 420 nm). The mass concentrations of volatile acids and the sensory characteristics of the wine materials and wines have been determined, too. The research has shown that in the medium dry wines obtained by cryotechnology, the concentrations of free terpene compounds increased from 1.01 mg/dm3 to 1.21 mg/dm3 in Rkatsiteli, and from 2.89 mg/dm3 to 3.24 mg/dm3 in Citronny Magaracha. The flavour and aroma improved substantially, too. So, the blending technology of producing medium dry and semi-sweet table wines using cryomust allows retaining, to the greatest possible degree, the bright and peculiar aroma of the grape variety, and obtaining the highest-quality wines of this type.

The article deals with a study of technological characteristics of avian fat. The fatty acid composition of goose, duck, chicken and turkey fats, comparative analysis of the differences in the content of saturated, monounsaturated and polyunsaturated fatty acids in each fat is described in a study. The characteristics of peroxide numbers of fresh greased fats and their deterioration under different oxidation regimes are presented in the article.
Investigations were conducted in conditions of forced spoilage in a drying cabinet at t=102 °Ϲ, until the total spoilage was reached after 4 months storage at a temperature 4±2°С. Samples were native fats, fats with the addition of traditional broad-spectrum spices (nutmeg, black pepper, fresh garlic, mustard powder) and their oil extracts. According to the results of the study of peroxide number of avian fats, initial values have been determined that characterized fats as fresh and suitable for storage, and differences in the rate of oxidation processes depending on the storage conditions, fatty acid composition and the presence of natural antioxidants. It has been found that avian fats are spoiled in the following sequence: 1 – goose, 2 – duck, 3 – chicken, 4 – turkey, depending on the different ratio of saturated and unsaturated fatty acids and individual resistance to damage. The results of studies have shown that the induction period of fats with the addition of natural antioxidants significantly increases, compared with native fats. This suggests that natural antioxidants not only increase the nutritional and biological value, but also serve as a free radical trap for fatty acids. Thus, fats stored for 4 months in the refrigerator do not significantly change the value of peroxide numbers, without exceeding the threshold value of 0.05 mmols ½O/kg, with the exception of goose ones. Therefore, enrichment of fat with mixtures of spices and their fat extracts is an alternative way to maintain the quality of fat and extend the shelf life of meat products. Taking into account their non-toxicity and accessibility, spices of natural origin are the best and safest option for the stabilization of edible fats and products to which they are included in accordance with the requirements of the Ministry of Health of Ukraine.
