A study of the theoretical and methodological aspects of balancing the interests of producers and consumers of recreational services in the regions of Ukraine is carried out. It is noted that the development of the recreational and tourist sphere for many countries is a very important task today, since the tourism industry is one of the main sources of income to the budget for them. Ukraine, located in the center of Europe at the crossroads of transport routes, with favorable natural and climatic conditions for the progressive advance of its recreational sphere, as well as significant historical and cultural potential, the necessary human and material resources, significantly lags behind most European countries in terms of development of recreational and tourist services. The factors influencing the price and quality of tourist services are defined. It is determined that the management of the balance of interests between the producer of tourist services (tour operator) and recreational needs of the population should be materialized on the basis of a set of properties and characteristics of products or services that provide them with the opportunity to meet the agreed or predictable needs of consumers. As result of the study, it is concluded that the price and quality of the tour package affect the balance of interests between the tour operator and the recreational needs of the population. To consider the pricing and proper quality, the factors influencing them are analyzed. It is determined that the most influential factor is: the theory of consumer behavior. The formation of the price of tourist services is influenced by the costs of the tour operator, which largely depend on contractors. To increase the balance of interests, it is necessary to better study the tourist demand and offer a variety of services at diversified prices. Managing the balance of interests of producers and consumers of recreational services in Ukraine should be based on the understanding that a tourist product is a specific one, and the quality determination largely depends on the factors of influence: volatility of quality, seasonality, etc.
Concession as a Form of Implementation of Public-Private Partnership Projects in Ukraine and World-Wide
Authors:   West Ukrainian National University, Shuliuk B. S.
Published: April 2021

The article is aimed at examining the peculiarities of implementation of public-private partnership concession projects in various sectors of the economy in both Ukraine and the world. The main approaches to understanding the essence of the concept of «concession» are considered and its characteristic features are defined. The procedure of operation of the concession mechanism is disclosed. Risks of public-private partnership participants in the process of implementation of concession projects in Ukraine are determined. The need to provide the State support to stimulate the participation of a private partner in long-term projects is substantiated. It is specified that such support should be provided in order to implement the most necessary public-private partnership projects to significantly improve the living conditions of the population in a particular region. It is determined that, unlike Ukraine, the concession mechanism is actively used in various sectors of the world economy, in particular, successfully implemented projects in the transport sector (roads, railways, ports, airports, pipeline transport), housing and communal services (water supply, water purification, electricity supply). At that, the transport industry dominates, while heat supply and waste treatment are the least popular. Prospects for further research in this direction are the search for ways to improve the domestic concession mechanism in the process of implementing public-private partnership projects, taking into account the best achievements of world experience. This will allow to attract financial resources of business in various forms of cooperation in terms of public-private partnerships, and, consequently, to improve the quality of services provided to the population.

In today’s information world, the competitiveness of universities is closely related to the effectiveness of the IT services provided. However, the development of IT infrastructure requires maintaining a balance between cost and efficiency of services. An IT service includes information technologies, processes and people. In accordance with ITIL standards, the university’s IT department should move from supporting software, applications, servers and networks to timely providing IT services to end users. The first step to this is to create a catalog of IT services. The purpose of the catalog implementation is to provide a single source of consistent information about all operational services and ensure quick access to them. Unlike foreign universities, domestic higher education institutions do not practice a systematic description of IT services and their presentation through the IT catalog. Direct transfer of management models of foreign universities to the Ukrainian educational environment appears impractical. The publication proposes a three-level catalog model, describes the categories of services that can be provided by Ukrainian universities, and defines the attributes of the IT service description template. The attributes of the description include: name, type of services, brief description, business owner, priority, service owner, consumers, request order, SLA, support system, status/phase. From the moment the IT service catalog is fully formed, its periodic monitoring begins according to the following criteria: SLA validity, correctness of provision of IT services, etc. The publication considers the formation of a catalog by stakeholders of the University on the example of the National University of Water Management and Environmental Management. In general, the use of the suggested recommendations will provide a description of the IT infrastructure of universities in the form of a set of services, the value of which is understandable to stakeholders and university management, as well as will allow to achieve competitive advantages in the educational services market.

Published: April 2021

The article is aimed at studying the methodologies of forecasting bankruptcy, their application in forensic economic expertise, which will allow to make managerial decisions substantiated from the point of view of financial security of an enterprise and create opportunities for stable functioning and development of the enterprise. All enterprises are affected by negative factors and may find themselves in a crisis situation. That is why the management of enterprise should apply all existing measures to prevent bankruptcy and overcome crisis situations. Any crisis situation can be corrected if you respond to crises in time and form a balanced and adequate management system. Therefore, the use of bankruptcy forecasting methodologies will allow the management of enterprise to identify in advance negative trends in its development. The article analyzed the existing discriminant models for determining the probability of bankruptcy with their application in forensic economic expertise. In modern practice of the financial-economic activities of foreign firms, to assess the probability of bankruptcy, the discriminant models of Altman, Beaver, Taffler, Tishaw and some others received the widest application. It is defined that for a more justified forecast, it is advisable to use several methods at the same time to predict the probability of insolvency (bankruptcy) of enterprise. It is proposed to use a set of models to determine the probability of bankruptcy of enterprise in solving issues of economic forensic expertise, which will significantly increase the degree of probability of the results obtained. The proposed measures can be used not only to diagnose the likelihood of bankruptcy, but also to develop anti-crisis measures.

Redystrybucja emerytalna jest pojęciem niezwykle złożonym, a przy tym stosunkowo rzadko badanym, choć występuje w systemach emerytalnych od początków ich powstania. Różnorodność formuł emerytalnych i narzędzi wykorzystywanych do dokonywania transferów redystrybucyjnych oraz konieczność dysponowania jednostkowymi danymi o wpływach i wydatkach z systemu emerytalnego w celu dokładnego oszacowania kierunków i siły transferów redystrybucyjnych, często uniemożliwia przeprowadzenie takiej analizy w ramach krajowych systemów emerytalnych, o analizie komparatywnej nie wspominając. Ponadto, możliwość przyjęcia różnych miar redystrybucji, uwzględniających zmieniające się czynniki ekonomiczne (stopy zwrotu, inflację, wysokość wynagrodzeń), czynniki społeczne (przebieg zatrudnienia, przyjęte tablice śmiertelności) i inne zmienne wpływające na relacje pomiędzy wpłaconymi składkami a kwotą otrzymanych świadczeń, czyni to zadanie jeszcze trudniejszym. W praktyce pomiar redystrybucji emerytalnej ma zwykle charakter przybliżony i opiera się na wyznaczaniu wskaźników redystrybucji dla wybranych grup ubezpieczonych. Za cenę pewnego uproszczenia rzeczywistości, analizy takie umożliwiają jednak zbadanie redystrybucji pod kątem skuteczności konkretnych narzędzi redystrybucyjnych zastosowanych w systemach emerytalnych. W przypadku analiz komparatywnych zastosowanie znajdują ogólne wskaźniki progresywności systemów emerytalnych, które posłużyć mogą jako miary symptomów występowania redystrybucji w systemach emerytalnych.
Ewolucja pracowniczych programów emerytalnych w reakcji na kryzys finansowy - tendencje zmian
Authors: Rutecka Joanna
Published: April 2021

Kryzys finansowy wpływa na funkcjonowanie wszystkich systemów emerytalnych – zarówno kapitałowych jak i repartycyjnych. W przypadku tych ostatnich oddziaływanie kryzysu, i związanego z nim kryzysu gospodarczego, wiąże się z mniejszymi wpływami z tytułu składek emerytalnych. Bardziej bezpośredni i natychmiastowy wpływ załamania na rynkach finansowych jest widoczny w przypadku rozwiązań kapitałowych – wówczas aktywa zgromadzone w funduszach emerytalnych zostają mocno przecenione, a kapitały przyszłych emerytów ulegają zmniejszeniu. Wśród różnych rozwiązań emerytalnych o charakterze kapitałowym, szczególne znaczenie odgrywają pracownicze programy emerytalne, które są tworzone z inicjatywy pracodawcy i oferują pracownikom uzupełnienie dochodów w okresie starości. Plany te podlegają zwykle mniejszym restrykcjom inwestycyjnym niż obowiązkowe fundusze emerytalne zaliczane do bazowych systemów emerytalnych, jednak większa swoboda inwestycyjna nie oznacza, iż są one w stanie uchronić się przed negatywnymi skutkami kryzysów finansowych. W artykule przeanalizowane zostało funkcjonowanie pracowniczych programów emerytalnych w Unii Europejskiej w czasie kryzysu finansowego i tuż po nim, ze szczególnym uwzględnieniem największych europejskich rynków: Holandii, Wielkiej Brytanii i Szwajcarii. Autorka zaprezentowała wpływ kryzysu finansowego na stopy zwrotu i wartość aktywów zgromadzonych w pracowniczych programach emerytalnych oraz omówiła zmiany wprowadzone w funkcjonowaniu pracowniczych planów emerytalnych w reakcji na załamanie na rynku finansowym.

ABSTRACTIn the current era of globalization, various human jobs depend on electrical equipment such as three-phase induction motors. Three-phase induction motors are very important to use according to their roles and functions. The occurrence of voltage variations in the electric power system is due to the magnitude of the voltages between the three phases which are not the same so that there are differences in the angle of the R, S and T phases, which causes an uneven load overload in the electrical distribution system. Among the disturbances that can occur are overvoltage, under voltage, unbalance voltage between phases, overload, and overheating. Based on these problems, a three-phase induction motor protection system was designed, the system uses current, voltage, temperature sensors, which functions to measure the value when a disturbance occurs, a magnetic contactor as a breaker and a liaison when the disturbance is given in accordance with the set point value given to the microcontroller. The results of the research for unbalanced voltage of V1 112 V, V2 114 V, V3 108 V, overvoltage of V1 228 V, V2 207 V, V3 264 V, over current of A1 104 A, A2 107 A, A3 0.77 A , the overload on the resistance source is 333 ?, 250 ?, 200 ?, 167 ?, and the overheating is 40.75 ºC at 6.5 minutes with tripping conditions in each test. The final results of this study indicate that the protection system which is designed is better used for three-phase induction motors.Keywords: unbalaced, disturbances, protection systems, sensors, magnetic contactor, microcontroller.

Published: April 2021

ABSTRACT Bengkulu is one of 34 provinces in Indonesia which is a megathrust region. So Bengkulu province is often hit by many large earthquakes with shallow depth. TEC anomaly was analyzed based on three electromagnetic waves radiated by an earthquake. The total electron content (TEC) anomaly is seen through the global positioning system (GPS) dual-frequency radio signal data. The continuous wavelet transform (CWT) method is used to divide the signal analysis into several sections according to the electromagnetic wave frequency range of acoustic (2.5 mHz) -3 mHz), gravity waves (1 mHz-2.8 mHz) and rayleigh waves (5 mHz-33 mHz). GPS observation data for 9 days is calculated using the Standard deviation (2?) method to see trends in data changes. The analysis shows anomalies in the September 12 2007 earthquake (7.9 Mw), the March 5 2010 earthquake (6.3 Mw) and the August 4 2011 earthquake (6.0 Mw). Anomalies are detected 1 to 5 hours before an earthquake occurs. TEC anomalies that occur may be related to the process of preseismic before the earthquake and may be an early sign of an earthquake.Keyword: earthquake, total electron content, continous wavelet transform, standard deviation

A Botânica estuda e classifica os vegetais considerando as formas, estruturas e composição; seu conhecimento está intimamente associado ao cotidiano das pessoas. Contudo, sua presença quase sempre é ignorada, de modo que, na Educação Básica, é vista como um conteúdo muito teórico, descritiva e desestimulante. Por isso, é importante saber a opinião do educando em relação à matéria e tentar promover melhorias nesta área, desta forma, objetivou-se averiguar o interesse em Botânica de alunos do Ensino Médio de duas escolas da rede pública de Fortaleza. Para tanto, foi aplicado um questionário a 71 alunos do 2º ano do Ensino Médio, de duas escolas da Rede Pública Estadual de Fortaleza, CE, composto de sete perguntas, indagando-os sobre as dificuldades encontradas por eles, a forma que o professor compartilha o conteúdo, sugestões para melhorar o entendimento na disciplina, dentre outras; também participaram da pesquisa os professores de Biologia das respectivas turmas pesquisadas, para saber sua opinião sobre o assunto e sua atuação em sala de aula. Verificou-se que a maioria dos alunos tem interesse por Botânica e acham relevante conhecer sobre o assunto, contudo apresentam algumas dificuldades, especialmente quanto à nomenclatura, de modo que o docente apresenta papel fundamental para facilitar o entendimento deste conteúdo.

Caffeine has been widely used to treat gynoid lipodystrophy (GLD). Despite caffeine has been considered as a promise treatment, there is a lack of scientific evidences regarding its effect on GLD when associated with iontophoresis or others equipment. We aimed to evaluate the effects of a caffeine gel alone and associated with iontophoresis in GLD treatment. In a single-blind randomized clinical trial, women with mild/moderate GLD in the buttocks were randomized to topical caffeine gel group (CG; n=10); caffeine gel plus iontophoresis group (CIG; n=11) or iontophoresis group (IG; n=10). The groups were treated with 10 sessions, two times/week, 20 min/session. The subjects were evaluated pre and post treatment by photonumeric GLD severity scale, ultrasound image, thermography and quality of life questionnaire with a blind evaluator. There were statistical reduction in subcutaneous tissue thickness (P≤0.046) as well as in subcutaneous tissue plus dermis thickness (P≤0.044) in buttocks both in CG and CIG. GLD reduction was similar between CG and CIG, and these reductions were more pronounced than in IG (P<0.0001). Furthermore, quality of life improved in all groups (P<0.017). We concluded that caffeine alone and associated with iontophoresis were effective for decreasing the subcutaneous fat layer in women with GLD.

Published: April 2021

Surf zones of sandy beaches are crucial environments for numerous fishes but one of the most challenging habitats when it comes to sampling, due to high-energy currents and waves. In this study, we compared the efficiency of 2 methods currently used to sample the biodiversity of shallow surf zone fish communities: the traditional method of beach seine nets and the more recently introduced surf zone Baited Remote Underwater Video Stations (surf-BRUVS). We applied both sampling strategies at 67 sites along 27 sandy beaches with different environmental characteristics in southeastern Brazil. We compared overall abundance, species richness, and beta (turnover) and functional trait diversity recorded from both methods. Our results showed that seine nets captured a higher species richness, greater abundance, greater functional richness and more functionally singular species than surf-BRUVS, particularly in areas with low wave energy. Beta diversity analyses, however, showed a clear difference in assemblage composition detected by each method regardless of environmental conditions, mainly driven by species turnover and variations in abundance. Only seine nets captured small species (<10 cm total length), while surf-BRUVS were more effective in recording larger species. Our results suggest that shallow surf zone assemblages sampled with surf-BRUVS and beach seine nets are almost totally taxonomically and highly functionally divergent, and the application of both methods provides complementary results. Additionally, the non-extractive nature of surf-BRUVS presents an opportunity for sampling vulnerable areas or species. However, when using a single method, researchers should take into consideration each method’s biases and be aware that biodiversity may be underestimated for certain groups.

РЕКОНСТРУКЦІЯ БУДИНКІВ ПЕРШИХ МАСОВИХ СЕРІЙ – ЗАСАДА СТАЛОГО РОЗВИТКУ МІКРОРАЙОНІВ І КВАРТАЛІВ МІСТ

Published: April 2021

Житлові будинки перших масових серій забудови 60-70 р. р. складають значну частину житлового фонду України. Основні тримальні конструкції більшості серій цих будинків знаходяться в задовільному стані і при належному ремонті можуть експлуатуватися ще 40 - 50 років. Модернізація фонду будинків перших масових серій пов’язана з втручанням у системи мікрорайонів і кварталів, які характеризують масову забудову. Руйнування цих систем суперечить принципам «Сталого розвитку» - «Sustainable development». Цей двослівний термін в Україні має застосовуватися як прямий переклад з мови оригіналу – «Прояви, що підтримують життя». На території України, в 60-70 р.р. були побудовані понад 5000 п'ятиповерхових великопанельних житлових будинків – головним чином серій 1-464 та 1-480. Конструктивні особливості великопанельних будинків дозволяють здійснити їх реконструкцію з обмеженим за розмірами і в часі втручанням в побут мешканців. Така реконструкція передбачає тільки зміну вертикальних розмірів будинку. Найбільш доцільними схемами для реконструкції будинків вказаних вище серій рекомендовані такі, що базуються на надбудові, або надбудові разом з прибудовою невеликих за розмірами у плані ризалітами у внутриквартальному просторі. Проблемою надбудов є застосування в перекриттях останнього поверху плит зі зниженим рівнем тримальної здатності. Виходом є влаштування подвійного роздільного перекриття. Конструктивна система «Фламінго» забезпечує надбудову п’яти поверхів і може бути застосована в якості вертикальних «акцентів» нової квартальної забудови. Технічне рішення системи полягає у створенні П-подібних тримальних рам на власних фундаментах. Ригелі рам стають основою простора, який використовується як технічний поверх. Найбільш придатними для реконструкції є будинки серії 1-480. Сучасні вимоги щодо реконструкції мікрорайонів п’яти поверхової забудови мають полягати в помірному збільшенні кількості поверхів будинків, без збільшення їх розмірів у плані. Надбудова додаткових поверхів має застосовуватися для створення вертикальних акцентів кварталів. Акцентами мікрорайонів повинні стати нові будівлі громадського призначення. Такі архітектурно містобудівні рішення в комплексі відповідатимуть концепції «сталого розвитку».

This research was conducted to study the reproductive cycle and fecundity of the fish Tristramella simonis in the Northern Great River (Nahr Alkabeer Alshmali) north of Lattakia city. 263 individuals were collected from the northern great river, during the period between July 2017 and June 2018. Samples were collected every 15 days using gill nets, which its pores diameter ranged from 16 to 20 mm and using cages (1 × 1 × 1 m). The total length of the collected fish ranged from 9.5 to 16.5 cm, and their weights ranged from 19.5 to 112.27 g. Samples contained (128 females) and (88 males) and (47) undetected. Results of Gonado Somatic Index (GSI) showed that the reproduction period was between April and August with three obvious peaks of maturity. Where the highest value of GSI was (10.06±8.46) % for females and (0.13 ± 0.05) % for males. Results of Hepato Somatic Index (HSI) was concurrence highly with the ecological and physiological changes, which result from changes in sexual activity during the reproductive cycle. Where the highest value of HSI attained 3.79 ± 1.86 % for females and attained 3.95 ± 1.38 % for males. In the first sexual maturity, the length attained 13.31 cm for females and (14.87 cm) for males. The sexual rate was (1: 0.7), which means 40.7 % males and 59.3 % females in the population. The absolute fecundity ranged from 940 to 1229 egg. While the relative fecundity ranged between 158- 215 egg/ g of ovary weight. Egg diameter during reproduction season ranged between 2.4- 4 mm, with several sizes, which mean a relatively long reproduction term.

The traceability mechanisms of wood harvesting and supply chains, environmental crimes, illegal logging, as well as the marking of forests, have been the subject of research in the last decade by domestic and foreign specialists in various fields of knowledge, including lawyers, economists, engineers, etc. In the era of the development of digital technologies, their use significantly contributes to the effectiveness of the activities of control and supervisory and law enforcement agencies. However, it is still not possible to form a system of up-to-date data on the state of Russia's forests, eradicate the facts of illegal actions with wood, optimize the process of tracking supply chains and reduce production costs without reducing product quality. The article revealed differences in theoretical approaches to the definition of the concept of «tracking system» in Russia and abroad. In addition, the analysis of the applied methods of marking harvested wood allowed the author to distinguish chipping using RFID - marks (radio frequency identification) as a modern method that allows not only to automatically identify an object, but also to exercise control over movement without providing direct visibility with it. In the conclusion of the article, the author presents a conceptual system for monitoring the state of the forests of Russia, formed on the basis of the EGAIS platform. It is also noted that the intended architecture of the system should have the ability to track the product in real time precisely in the forest, as well as outside it - from suppliers and manufacturers who can use this information to make business decisions. An ideal version of the functionality of the tracking system is presented as the ability of the consumer through a mobile application to obtain information about the product in accordance with the logic and logistics chain (from the place where the tree grows - the rock - the age of the cutting - the harvester - the manufacturer).
COUNTERVAILING RISK MANAGEMENT IN THE FOREST SECTOR THROUGH EXCHANGE-TRADED INSTRUMENTS: CONDINIONS AND DEVELOPMENT PROSPECTS

For the world community, 2020 marked the beginning of change on a global scale. Pulmonary disease epidemic, which spread at a lightning speed throughout the globe, not only exposed the negative aspects of globalization, multicultural society and single economic plateaus, but also provided opportunities for the formation of new trends in economic management. In isolation, positive dynamics were observed in areas with on-line trade opportunities, and negative in traditional energy markets. In this regard, the author carried out a comprehensive analysis of the financial instruments used on the exchange, which made it possible to form a comparative characteristic of hedging, option, futures, derivative and forward. The relationship between the values of wood and the forest area on which it grows has been established and presented by the inequality system. Methods of compounding and discounting are considered in detail, on the basis of which a mechanism for determining the net present value of the cost of growing forest plantations as a capital benefit is proposed. The author gives a calculation of the costs of growing ordinary pine seedlings, and a comparison of the weighted average interest rate on deposits (in rubles) and average inflation, made it possible to prove the investment attractiveness of forestry not only for private business, but also for the state. The study provides an overview of the practices of leading «forest» States on interest rates applied to forest investment. In the conclusion of the article, the author concludes that compensatory risk management in the forest industry is possible using the hedging mechanism of measures by concluding forward contracts for the cultivation of seedlings of a certain tree species.

The article is of theoretical and methodological nature and allows you to look at the methodological problems of managing a modern metropolis from various theoretical-economic and conceptual-philosophical perspectives. The authors consider various approaches to understanding the specifics of the urban environment and global social shifts connected with an increase of the concentration of the population of various countries within large megalopolises and a shrinkage of economic space; they also analyze the socio-economic, cultural and worldview aspects predetermined by these tendencies. A distinctive feature is a systematic view of the processes taking place in megalopolises under the influence of modern trends in informatization and digitalization of social development. The article considers the megalopolis as an object of scientific knowledge, assesses the relationship of urban studies, as an extremely important modern interdisciplinary science with other sciences, which makes it possible to understand the internal laws of the development of large cities, and presents the current trends and contradictions of their development.

Published: April 2021

A set of legislative instruments regulating market abuse have been adopted by the European Union. As regards criminal law sanctions, the principal contemporary legislative instrument in this field, addressed to its Member States, is the Directive 2014/57/EU on criminal sanctions for market abuse. Legislation has been supplemented by the case-law of the Court of Justice of the European Union (formerly known as the Court of Justice of the European Communities). It is a key element for the development of legal practice in all Member States of the European Union. The assessment of case-law on criminal issues within market abuse is therefore needed. The paper analyses relevant cases. In each case at the outset a reference for a preliminary ruling is mentioned. Further, dispute in the main proceedings and the question(s) referred for a preliminary ruling are analysed. The most important parts of analyses are considerations by the Court of Justice and its rulings.
ON THE INEXTRICABLE LINK BETWEEN THE PERSONALITY OF THE PARTICIPANT AND THE SOCIETY ON THE EXAMPLE OF LAW ENFORCEMENT PRACTICE ON BRINGING THE DEBTOR'S CONTROLLING PERSONS TO SUBSIDIARY LIABILITY

The purpose of the research. Bankruptcy proceedings increasingly involve not only controlling persons but also members of their families. The reason for this is the conflict of interests of the family and creditors. The development of bankruptcy legislation leads to a reduction in the possibilities of preserving the property of family members from collection under the obligations of the controlling person of the debtor. Until recently, one of these methods was the alienation of property in favor of a minor, which undoubtedly led to a violation of creditors' interests. The need to protect creditors' interests gave rise to new specific forms of lawmaking by the higher courts, in particular, bringing the children of the controlling debtor to responsibility. This decision seems to be controversial. This is the exhaustion of the theory of independent legal personality of a legal entity and the lack of a theoretical justification for the implementation of entrepreneurial activities of citizens in the form of participation (membership) in a legal entity. The article aims to identify sources of legal uncertainty in bringing the children of the controlling debtor to respond within bankruptcy procedures. The article analyzes the judicial practice in cases of bringing family members of a controlling debtor, including children, as controlling beneficiaries, to subsidiary liability for society's obligations through the prism of the conscientiousness of the exercise of parental rights and the conscientiousness of a minor. Results. It is proposed to introduce into legislation two presumptions: a refutable presumption of the conscientiousness of a parent and an irrefutable presumption of a child's good faith as a tool to save a minor from civil death through the fault of the parents.

Social media have become useful tools for audiovisual promotion, especially to reach niche audiences. Twitter promotional strategies have been widely studied, yet other growing platforms such as Instagram have been less analyzed. This paper examines the Instagram promotional strategies of two pay-per-view platforms (HBO and Netflix) in two markets (the United States and Spain). A total of 731 messages, posted between May and November 2017, were analyzed to identify their formal features, objectives, and their content’s emotional and cognitive elements posted on HBO and Netflix’s Spanish and U.S. accounts. The results showed acute differences between how HBO and Netflix use their Instagram accounts in the two markets (Spain and the United States). The Spanish accounts mostly provided information, while the American accounts both provided information and promoted program content. Posts from U.S. accounts more frequently included links to social media, particularly to celebrity accounts. Spanish accounts relied more on diegetic images, whereas U.S. accounts emphasized non-diegetic and off-set images. Netflix used humor more than HBO did, and a stronger focus on celebrities. Humor and positive tone were found to be linked to higher engagement.
Alternative Telecasts and the Ongoing Fracturing of Sports Television
Authors: Buehler Branden
Published: April 2021

Several media companies have recently experimented with expanding their television coverage of major sporting events across multiple outlets, offering traditional telecasts on their flagship channels while adding alternative telecasts on secondary outlets. Significantly, unlike most second-screen experiences, the alternative telecasts offered on secondary outlets have largely been meant not to complement the traditional telecasts but rather to substitute for them. In order to better understand what this new model of sports telecasting means for the present and future of sports television, this article is split into two parts. First, the article traces the rise of alternative telecasts, in the process distinguishing them from second-screen experiences and explaining their industrial origins. Second, the article examines how alternative telecasts contribute to the ongoing fracturing of sports television and, in the process, both continue to erode the communal engagement of sports television and reshape the genre’s relationship to its audiences.
