Published: March 2020

Dynamics of ocean current-induced island wake has been an important issue in global oceanography. Green Island, a small island located off southeast of Taiwan on the Kuroshio path was selected as the study area to more understand the spatial structure and temporal variation of well-organized vortices formed by the interaction between the Kuroshio and the island. Sea surface temperature (SST) and chlorophyll-a (Chl-a) concentration data derived from the Himawari-8 satellite and the second generation global imager (SGLI) of global change observation mission (GCOM-C) were used in this study. The spatial SST and Chl-a variations in designed observation lines and the cooling zone transitions on the left and right sides of the vortices were investigated using 250 m spatial resolution GCOM-C data. The Massachusetts Institute of Technology general circulation model (MITgcm) simulation confirmed that the positive and negative vortices were sequentially detached from each other in a few hours. In addition, totals of 101 vortexes from July 2015 to December 2019 were calculated from the 1-h temporal resolution Himawari-8 imagery. The average vortex propagation speed was 0.95 m/s. Totals of 38 cases of two continuous vortices suggested that the average vortex shedding period is 14.8 h with 1.15 m/s of the average incoming surface current speed of Green Island, and the results agreed to the ideal Strouhal-Reynolds number fitting curve relation. Combined with the satellite observation and numerical model simulation, this study demonstrates the structure of the wake area could change quickly, and the water may mix in different vorticity states for each observation station.

Published: March 2020

In this paper, we describe how researchers and weather forecasters work together to make satellite sounding data sets more useful in severe weather forecasting applications through participation in National Oceanic and Atmospheric Administration (NOAA)’s Hazardous Weather Testbed (HWT) and JPSS Proving Ground and Risk Reduction (PGRR) program. The HWT provides a forum for collaboration to improve products ahead of widespread operational deployment. We found that the utilization of the NOAA-Unique Combined Atmospheric Processing System (NUCAPS) soundings was improved when the product developer and forecaster directly communicated to overcome misunderstandings and to refine user requirements. Here we share our adaptive strategy for (1) assessing when and where NUCAPS soundings improved operational forecasts by using real, convective case studies and (2) working to increase NUCAPS utilization by improving existing products through direct, face-to-face interaction. Our goal is to discuss the lessons we learned and to share both our successes and challenges working with the weather forecasting community in designing, refining, and promoting novel products. We foresee that our experience in the NUCAPS product development life cycle may be relevant to other communities who can then build on these strategies to transition their products from research to operations (and operations back to research) within the satellite meteorological community.
Pars pro toto—Remote Sensing Data for the Reconstruction of a Rounded Chalcolithic Site from NE Romania: The Case of Ripiceni–Holm Settlement (Cucuteni Culture)
Authors: Asăndulesei Andrei , Tencariu Felix Adrian , Nicu Ionut Cristi
Published: March 2020

Prehistoric sites in NE Romania are facing major threats more than ever, both from natural and human-induced hazards. One of the main reasons are the climate change determined natural disasters, but human-induced activities should also not be neglected. The situation is critical for Chalcolithic sites, with a very high density in the region and minimal traces at the surface, that are greatly affected by one or more natural hazards and/or anthropic interventions. The case study, Ripiceni–Holm, belonging to Cucuteni culture, is one of the most important Chalcolithic discoveries in the region. It is also the first evidence from Romania of a concentric arrangement of buildings in the proto-urban mega-sites tradition in Cucuteni-Trypillia cultural complex, and a solid piece of evidence in terms of irreversible natural and anthropic destruction. Using archival cartographic material, alongside non-destructive and high-resolution airborne sensing and ground-based geophysical techniques (LiDAR, total field and vertical gradient magnetometry), we managed to detect diachronic erosion processes for 31 years, to identify a complex internal spatial organization of the actual site and to outline a possible layout of the initial extent of the settlement. The erosion was determined with the help of the DSAS tool and highlighted an average erosion rate of 0.96 m/year. The main results argue a high percent of site destruction (approximately 45%) and the presence of an active shoreline affecting the integrity of the cultural layer.
Novel Soil Moisture Estimates Combining the Ensemble Kalman Filter Data Assimilation and the Method of Breeding Growing Modes
Authors: Li Yize , Shu Hong , Mousa B. G. , Jiao Zhenhang
Published: March 2020

Soil moisture plays an important role in climate prediction and drought monitoring. Data assimilation, as a method of integrating multi-geographic spatial data, plays an increasingly important role in estimating soil moisture. Model prediction error, an important part of the background field information, occupies a position that could not be ignored in data assimilation. The model prediction error in data assimilation consists of three parts: forcing data error, initial field error, and model error. However, the influence of model error in current data assimilation methods has not been completely considered in many studies. Therefore, we proposed a theoretical framework of the ensemble Kalman filter (EnKF) data assimilation based on the breeding of growing modes (BGM) method. This framework used the BGM method to perturb the initial field error term w of EnKF, and the EnKF data assimilation to assimilate the data to obtain the soil moisture analysis value. The feasibility and superiority of the proposed framework were verified, taking into consideration breeding length and ensemble size through experiments. We conducted experiments and evaluated the accuracy of the BGM and the Monte Carlo (MC) methods. The experiment showed that the BGM method could improve the estimation accuracy of the assimilated soil moisture and solve the problem of model error which is not fully expressed in data assimilation. This study can be widely used in data assimilation and has a significant role in weather forecast and drought monitoring.
Exploration for Object Mapping Guided by Environmental Semantics using UAVs

Published: March 2020

This paper presents a strategy to autonomously explore unknown indoor environments, focusing on 3D mapping of the environment and performing grid level semantic labeling to identify all available objects. Unlike conventional exploration techniques that utilize geometric heuristics and information gain theory on an occupancy grid map, the work presented in this paper considers semantic information, such as the class of objects, in order to gear the exploration towards environmental segmentation and object labeling. The proposed approach utilizes deep learning to map 2D semantically segmented images into 3D semantic point clouds that encapsulate both occupancy and semantic annotations. A next-best-view exploration algorithm is employed to iteratively explore and label all the objects in the environment using a novel utility function that balances exploration and semantic object labeling. The proposed strategy was evaluated in a realistically simulated indoor environment, and results were benchmarked against other exploration strategies.
Precision and Reliability of Tightly Coupled PPP GNSS and Landmark Monocular Vision Positioning
Authors: Pang Menglin , Tiberius Christian
Published: March 2020

This paper presents an approach to analyse the quality, in terms of precision and reliability, of a system which integrates—at the observation-level—landmark positions and GNSS measurements, obtained with a single camera and a digital map, and a single frequency GNSS receiver respectively. We illustrate the analysis by means of design computations, and we present the actual performance by means of a small experiment in practice. It is shown that the integration model is able to produce a position solution even when both sensors individually fail to do so. With realistic assumptions on measurement noise, the proposed integrated, low-cost system can deliver a horizontal position with a precision of better than half a meter. The external reliability of the integrated system is at the few decimetre-level, showing that the impact of undetected faults in the measurements, for instance incorrectly identified landmarks in the image, on the horizontal position is limited and acceptable, thereby confirming the fault-robustness of the system.
The Teletalker – A Design Researcher’s Tool to Explore Intergenerational Online Video Connectivity in-the-Wild
Authors: Markowski Marianne
Published: March 2020

Although a fair amount of research around older adults’ perception of digital technology exists, there is only a moderate amount of research investigating older people’s reactions and sense-making in real-world contexts with emerging digital tools. This paper reports on the constructivist research approach used by the author, which initiated co-production with participants to gather older and younger adults’ reactions towards digital video connectivity during a series of design research interventions. For this, the author had built a research tool, the Teletalker kiosks (TT), which connected two locations using digital live video to provide a ‘window into the other space’. Participants, if they wished, could activate the volume with a designed mechanism aimed at non-computer literate people, which was used in order to speak to each other. The three connections were between an older people’s charity day centre and the university, between two locations at the university, and between two-day centres in the U.K. The returns collected revealed overall positive reactions towards video connectivity by younger adults and mixed reactions by older adults. The design for the volume mechanism did not work as expected for both groups. The interventions also brought out opinions and conformity dynamics within groups of older adults and attitudes by younger audiences towards older people. More research is needed to understand these reactions and attitudes in comparable contexts.
Uncertainty in Flood Mitigation Practices: Assessing the Economic Benefits of Property Acquisition and Elevation in Flood-Prone Communities
Authors: Mobley William , Atoba Kayode O. , Highfield Wesley E.
Published: March 2020

Adopting effective flood mitigation practices for repetitive flood events in the United States continues to play a prominent role in preventing future damage and fostering resilience to residential flooding. Two common mitigation practices for reducing residential flood risk consist of raising an existing structure to or above base flood elevation (BFE) and acquiring chronically damaged properties in flood prone areas and restoring them back to serve their natural functions as green open spaces. However, due to data accuracy limitations, decision makers are faced with the challenge of identifying the financially optimal approach to implementing mitigation measures. We address this problem through the following research questions: What does the optimal allocation of flood mitigation resources look like under data uncertainty, and what are the optimal methods to combining mitigation measures with consideration for the best economic benefits? Using a robust decision making (RDM) approach, the effects of uncertainty in property values, construction and demolition costs, and policy implementation options such as structure selection and budget allocation were measured. Our results indicate that the amount budgeted for mitigation and how those funds are allocated directly influence the selection of the most economically viable mitigation practices. Our research also contributes to the growing need for evaluating specific flood mitigation strategies.

While a number of machine learning (ML) models have been used to estimate RE, systematic evaluation and comparison of these models are still limited. In this study, we developed three traditional ML models and a deep learning (DL) model, stacked autoencoders (SAE), to estimate RE in northern China’s grasslands. The four models were trained with two strategies: training for all of northern China’s grasslands and separate training for the alpine and temperate grasslands. Our results showed that all four ML models estimated RE in northern China’s grasslands fairly well, while the SAE model performed best (R2 = 0.858, RMSE = 0.472 gC m−2 d−1, MAE = 0.304 gC m−2 d−1). Models trained with the two strategies had almost identical performances. The enhanced vegetation index and soil organic carbon density (SOCD) were the two most important environmental variables for estimating RE in the grasslands of northern China. Air temperature (Ta) was more important than the growing season land surface water index (LSWI) in the alpine grasslands, while the LSWI was more important than Ta in the temperate grasslands. These findings may promote the application of DL models and the inclusion of SOCD for RE estimates with increased accuracy.

The purpose of this study was to investigate the trajectories of multicultural adolescents’ ego-resilience, to compare the effects of neglectful parenting and bilingual competency on the trajectories, and to analyze the longitudinal mediation effect of ego-resilience on these variables’ influence to acculturative stress. In order to accomplish these aims, analysis was conducted using the data of 1,392 adolescents from the Multicultural Adolescents Panel Study. For statistical analysis, AMOS 20.0 was utilized for latent growth modeling and structural equation modeling. Results indicated: (1) a quadratic increase in ego-resilience of multicultural adolescents; (2) a difference in the trajectory of ego-resilience according to gender, with males displaying lower initial values and more rapid growth; (3) significant effects of neglectful parenting and bilingual competency on the trajectories of ego-resilience; and (4) mediating effects of ego-resilience between (a) neglectful parenting and acculturative stress, and (b) bilingual competence and acculturative stress. In accordance with the view of adolescents as prospective leaders in promoting a sustainable future, this study offers insight on the positive psychosocial development and well-being of multicultural adolescents.
Hybridized Intelligent Home Renewable Energy Management System for Smart Grids
Authors: Ma Yonghong , Li Baixuan
Published: March 2020

The incorporation of renewable energies and power storage at distribution facilities are one of the important features in the smart grid. In this paper, a hybridized intelligent home renewable energy management system (HIHREM) that combines solar energy and energy storage services with the smart home is planned based on the demand response and time of consumption pricing is applied to programs that offer discounts to consumers that reduce their energy consumption during high demand periods. The system is designed and handled with minimal energy requirements at home through installation of renewable energy, preparation, and arrangement of power stream during peak and off-peak periods. The best energy utilization of residential buildings with various overlapping purposes is one of the most difficult issues correlated with the implementation of intelligent micro-network systems. A major component of the smart grid, the domestic energy control system (HIHREM) provides many benefits, such as power bill reductions, reduction in wind generation, and demand compliance. This showed that the proposed energy scheduling method minimizes the energy consumption by 48% and maximizes the renewable energy consumed at the rate 65% of the total energy generated. A new model for smart homes with renewable energies is introduced in this report. The proposed HIHREM method achieves high performance and reduces cost-utility.
The Theorized Relationship between Organizational (Non)Compliance with the United Nations Guiding Principles on Human Rights and Desired Employee Workplace Outcomes

Published: March 2020

Despite the presence of guiding legislation such as the United Nations Guiding Principles, respect for human rights is subject to the conscience of organizational actors. Given that some transnational corporations are more powerful than nation states, they play an important role in the economies in which they operate, often with far-reaching impact on the labor conditions and human rights protections within these countries. In the current global context, respect for human rights may be undermined when organizational decision-makers are tempted to ignore unethical practices due to considerations such as competition and short-term financial incentives. We propose that the higher standards to which younger generations increasingly hold corporations provide a compelling and “business case” incentive for the protection of human rights of external stakeholders by organizational decision-makers. Drawing on related research on corporate social responsibility and on projections regarding demographical changes in the workplace worldwide, we make the case for a bottom-line advantage to respecting human rights in attracting and retaining top talent in work organizations. We conclude by highlighting the theoretical and practical implications of our theorizing.
Ecological Land Adaptive Planning in Macroscale, Mesoscale, and Microscale of Shanghai

Published: March 2020

The urban ecosystems in China have been compromised during the process of urbanization. The declining services of ecological lands have hindered the sustainable development of cities and the current ecological land management (regulations, rules, and laws) in China cannot meet the demand of future development. In this paper, a new multiscale systematic adaptive ecological land planning method is proposed. Shanghai, a typical mega-city in China, was chosen as the research area. To scientifically and adaptively manage ecological land, downscale management was used and macroscales (city), mesoscales (town), and microscales (community) were chosen. In different scales, different indicators were chosen as evaluation criteria to evaluate the services of the lands. At the mesoscale, habitat quality, carbon sequestration, water conservation, and soil fertility maintenance were chosen. At the mesoscale, habitat quality, carbon sequestration capacity, water production service and food supply were chosen as the evaluation criteria. These indicators are used to evaluate the importance levels of corresponding areas. Based on the importance levels of macroscales and mesoscales, three different scenarios with different targets of Changtian Community were proposed. All three scenarios were judged by stakeholders (residents and managers) of the community and a final scenario was proposed to meet all the requirements. This research not only provides theoretical reference and technical support for ecological land management in different scales of Shanghai, but also provides a new method of adaptive ecological land planning in megacities.

Authors: Peng Jingyao , Sun Yidi , Song Junnian , Yang Wei
Published: March 2020

It is a very urgent issue to reduce energy-related carbon emissions in China. The three northeastern provinces (Heilongjiang (HLJ), Jilin (JL), and Liaoning (LN)) are typical heavy industrial regions in China, playing an important role in the national carbon emission reduction target. In this study, we analyzed the energy consumption, carbon dioxide (CO2) emissions, and CO2 emission intensity of each sector in the three regions, and we compared them with the national level and those of China’s most developed province Guangdong (GD). Then, based on an input–output (I–O) framework, linkage analysis of production and CO2 emission from sector–system and sector–sector dimensions was conducted. The results showed that the three regions accounted for about 1/10 of China’s energy consumption and 1/6 of China’s CO2 emissions in 2012. In addition, the level of energy structure, CO2 emission intensity, and sectoral structure lagged behind China’s average level, much lower than those for GD. According to the sectoral characteristics of each region and unified backward/forward linkages of production and CO2 emissions, we divided sectoral clusters into those whose development was to be encouraged and those whose development was to be restricted. The results of this paper could provide policy–makers with reference to exploring potential pathways toward energy-related carbon emission reduction in heavy industrial regions.
Tourism and Altruistic Intention: Volunteer Tourism Development and Self-Interested Value
Authors: Han Heesup , Lee Soyeun , Hyun Sunghyup Sean
Published: March 2020

Volunteer tourism is indisputably an emerging trend in the tourism industry across the globe. Yet, little is known about the altruistic behavior of volunteer travelers. To fill this void, this research explores the convoluted relationships among memorable experience, awareness of problem, social norm, psychological resilience, personal norm, and self-interested value in driving altruistic intention. A field survey was conducted with a quantitative approach. The result reveals that psychological resilience and personal norm are direct determinants of altruistic intention while mediating the influence of awareness of problem and social norm on intention. In addition, memorable experience along with awareness of problem significantly induced volunteer travelers’ psychological resilience. Moreover, the test for metric invariance shows that the relationships between psychological resilience, personal norm, and altruistic intention are under the significant influence of volunteer travelers’ self-interested value. Overall, the variance in altruistic intention for volunteer tourism is satisfactorily explained by our suggested theoretical framework.
Co-Acquired Nanovirus and Geminivirus Exhibit a Contrasted Localization within Their Common Aphid Vector

Published: March 2020

Single-stranded DNA (ssDNA) plant viruses belong to the families Geminiviridae and Nanoviridae. They are transmitted by Hemipteran insects in a circulative, mostly non-propagative, manner. While geminiviruses are transmitted by leafhoppers, treehoppers, whiteflies and aphids, nanoviruses are transmitted exclusively by aphids. Circulative transmission involves complex virus–vector interactions in which epithelial cells have to be crossed and defense mechanisms counteracted. Vector taxa are considered a relevant taxonomic criterion for virus classification, indicating that viruses can evolve specific interactions with their vectors. Thus, we predicted that, although nanoviruses and geminiviruses represent related viral families, they have evolved distinct interactions with their vector. This prediction is also supported by the non-structural Nuclear Shuttle Protein (NSP) that is involved in vector transmission in nanoviruses but has no similar function in geminiviruses. Thanks to the recent discovery of aphid-transmitted geminiviruses, this prediction could be tested for the geminivirus alfalfa leaf curl virus (ALCV) and the nanovirus faba bean necrotic stunt virus (FBNSV) in their common vector, Aphis craccivora. Estimations of viral load in midgut and head of aphids, precise localization of viral DNA in cells of insect vectors and host plants, and virus transmission tests revealed that the pathway of the two viruses across the body of their common vector differs both quantitatively and qualitatively.

Newcastle disease (ND) is a highly contagious avian disease, causing considerable economic losses to the poultry industry. To obtain a safe, inexpensive, and effective ND vaccine to meet the international trade requirements of differentiating infected from vaccinated animals (DIVA), here we report the production of Oryza sativa recombinant fusion (F) protein in stably transformed transgenic rice seeds via agroinfiltration. The F protein expression level was enhanced 3.6-fold with a genetic background in low glutelin. Inoculation of plant-produced F antigen into Specific Pathogen Free (SPF) chickens markedly elicited neutralizing antibody responses against homologous and heterologous ND virus strains. Two doses of 4.5 μg fully protected chickens from a lethal ND challenge without any clinical symptoms. The mean weight gain of F protein-immunized chickens within 15 days after challenge was significantly higher than that of traditional whole virus vaccine-immunized chickens, thereby obtaining higher economic benefits. Moreover, the sera from the chickens vaccinated with the plant-produced F vaccine did not show reactivity in an immunochromatographic strip targeting the haemagglutinin-neuraminidase protein (HN) protein, and DIVA could be achieved within 10 minutes. Our results demonstrate that the plant-derived F vaccine along with immunochromatographic strips could be useful in the implementation of an NDV eradication program.

Published: March 2020

For the third time in four years, record-breaking flooding occurred in South Carolina. Hurricane Florence, which made landfall near Wrightsville Beach, North Carolina, on September 14, 2018, moved slowly across South Carolina from September 14–17, 2018. Over those four days, heavy rain fell over portions of the Pee Dee Watershed and eastern North Carolina, with over 30 inches of rain measured by an observer in Swansboro, North Carolina. Most of the excessive rainfall was confined to the Pee Dee region, with reported totals of over 24 inches in Horry County, while closer to the Savannah River Valley observers measured less than an inch of rain. Unlike the more recent flooding events across the state, not as many rainfall records were set during this event. The amount of rainfall at various locations, and at different time intervals (1-day, 2-day, 3-day, and 4-day), had a statistical probability of occurrence of 0.1%, or 1 in 1,000 chance of happening in any given year, according to the National Oceanic and Atmospheric Administration (NOAA) Atlas 14 (Bonnin et al., 2004). The rainfall associated with Hurricane Florence produced a long duration and significant flood that impacted many of the same communities still recovering from the October 2015 floods and Hurricane Matthew in 2016. Many of the rivers and streams within the Pee Dee Watershed experienced major or extreme flooding, with six stream gauges reaching record peaks, some surpassing the records set in 2016. This report provides an overview of the antecedent conditions, a synoptic summary of the event, and documentation on the meteorological and hydrological impacts observed across the Palmetto State.
COLOR M-MODE PROPAGATION VELOCITY (VP) TO ASSESS THE LEFT VENTRICULAR DIASTOLIC FUNCTION IN HYPERTENSION PATIENTS
Authors: Hoang Nhat Hau , Nguyen Anh Vu
Published: March 2020

Objective: To evaluate the color M-mode (Vp) propagation velocity parameter and the correlation between Vp and left ventricular diastolic function parameters in hypertension patients.
Subjects and Methods: A echocardiography study of 51 hypertensive patients, admitted to the Department of Cardiology of Hue University of Medicine and Pharmacy Hospital. This is a cross-sectional study.
Results: The Vp value was 63.34 ± 28.22 cm/s. In the left ventricular hypertrophy group, the Vp was lower (62.68 ± 28.08 cm/s) than Vp of the left ventricular non hypertrophy group but not significative (p > 0.05). We found clearly a diminution of the Vp in the groupe with degree 2 of diastolic dysfunction (Vp = 36.18 ± 4.17 cm/s) in comparison with degree 1 (55.65 ± 21.43 cm/s). Vp was positively correlated with the left ventricular peak E-wave velocity (r = 0.304, p < 0.05) and the E/A wave ratio (r = 0.319, p < 0.05). In addition, Vp was inversely correlated with ventricular septal thickness (r = - 0.372, p < 0.01) and left ventricular post wall (r = -0.347; p < 0.01).
Conclusion: The Vp parameter may be used as a complement parameters to assess the left ventricular diastolic function in hypertensive patients. This parameter is valuable in patients with 2 stage or more of diastolic function disorder.

Published: March 2020

Wearable and implantable electronics (WIEs) are more and more important and attractive to the public, and they have had positive influences on all aspects of our lives. As a bridge between wearable electronics and their surrounding environment and users, sensors are core components of WIEs and determine the implementation of their many functions. Although the existing sensor technology has evolved to a very advanced level with the rapid progress of advanced materials and nanotechnology, most of them still need external power supply, like batteries, which could cause problems that are difficult to track, recycle, and miniaturize, as well as possible environmental pollution and health hazards. In the past decades, based upon piezoelectric, pyroelectric, and triboelectric effect, various kinds of nanogenerators (NGs) were proposed which are capable of responding to a variety of mechanical movements, such as breeze, body drive, muscle stretch, sound/ultrasound, noise, mechanical vibration, and blood flow, and they had been widely used as self-powered sensors and micro-nanoenergy and blue energy harvesters. This review focuses on the applications of self-powered generators as implantable and wearable sensors in health monitoring, biosensor, human-computer interaction, and other fields. The existing problems and future prospects are also discussed.
Observed melt-season snowpack evolution on the Greenland ice sheet
Authors: Charalampidis Charalampos , Van As Dirk
Published: March 2020

Due to recent warm and record-warm summers in Greenland (Nghiem et al. 2012), the melt of the ice-sheet surface and the subsequent runoff are increasing (Shepherd et al. 2012). About 84% of the mass loss from the Greenland ice sheet between 2009 and 2012 resulted from increased surface runoff (Enderlin et al. 2014). The largest melt occurs in the ablation zone, the low marginal area of the ice sheet (Van As et al. 2014), where melt exceeds wintertime accumulation and bare ice is thus exposed during each melt season. In the higher regions of the ice sheet (i.e. the accumulation area), melt is limited and the snow cover persists throughout the year. It is in the vast latter area that models struggle to calculate certain mass fluxes with accuracy. A better understanding of processes such as meltwater percolation and refreezing in snow and firn is crucial for more accurate Greenland ice-sheet mass-budget estimates (Van Angelen et al. 2013).

Published: March 2020

Objective – The global industry is transforming into a digital world, evidenced by digital transformation performed by almost all of the industry sectors. One of the digital drivers is the support of connectivity provided by the telecommunication industry. The increasing mobile subscribers, along with the growth of mobile data traffic, is the sign of digital transformation itself. However, the rise of OTT (Over the Top) service providers tends to acquire the revenue share of the current telecom industry, seeing the trend of voice and SMS revenue that projected to decline.
Methodology/Technique – This research is intended to measure the impact of increasing mobile data traffic that mostly caused by OTT services to telecom efficiency. The efficiency measurement & analysis were performed using the Stochastic Frontier Approach (SFA) & Data Envelopment Analysis (DEA) method.
Findings – By using the SFA method, Maxis (Malaysia) got the highest efficiency score (0.98), followed by AIS (Thailand) with efficiency score 0.94 and Indosat Ooredoo (Indonesia) as the least efficient telecom provider (0.5). However, by using the DEA method, TLKM (Indonesia) got the highest efficient (0.98), and Celcom Axiata (Malaysia) was the least efficient (0.73/0.8).
Novelty – The compelling results of this study are variable total asset variable had a significant negative impact on the efficiency score, and the variable of mobile data traffic was not significantly impacting the efficiency value (t-Ratio 0.71).
Type of Paper: Empirical.

Keywords: Telecom Operators; Efficiency; Mobile Data Traffic

КРИТИЧНИЙ ДИСКУРС ІНТЕРПРЕТАЦІЇ БАЛЕТНОЇ КЛАСИКИ ДРУГОЇ ПОЛ. 1920 – ПЕРШОЇ ПОЛ. 1930-х РОКІВ
Authors: Підлипська Аліна
Published: March 2020

З’ясовується роль критичного дискурсу у формуванні явища «радянський класичний балет». Зауважена можливість виокремити дві стратегії щодо інтерпретації класичної балетної спадщини у радянському балеті – автентичне відтворення авторської редакції (реставрація) й інтерпретація балетної вистави згідно з ідеологічними приписами партійних інстанцій. Використання класичної спадщини у владних цілях, наповнення її ідейним змістом, паритетність пізнавальної та дієвої функцій мистецтва у процесі інтерпретації спадщини, наближення балетів минулого до нового глядача, орієнтація на його інтереси (А. Луначарський, М. Ліфшиць, І. Соллертинський) – ці ракурси цілком відповідали реалістичним тенденціям у мистецтві, не заперечувалися як представниками різних дискурсів, так і правлячою елітою.
РЕСТАВРАЦІЯ БАЛЕТІВ ХІХ СТОЛІТТЯ ЯК ТРЕНД
Authors: Перова Ганна , Гладка Людмила
Published: March 2020

Реставрація балетів ХІХ століття – один із трендів балетного театру кінця ХХ – початку ХХІ ст. Серед сучасних теоретиків та практиків балету сформувалися полярні думки щодо користі та перспективності реставрацій й рівня балетмейстерського креативу реставраторів. Провідні балетмейстери-реставратори кінця ХХ – початку ХХІ ст. – М. Ходсон, С. Вихарев, О. Ратманський, Ю. Бурлака. Основними проблемами виявилися: складність відтворення танцювальної стилістики балету ХІХ ст., що пов’язано з примусом артистів, особливо солістів, відмовитись від попереднього виконавського досвіду; невідповідність пантомімічних елементів сучасному лексичному темпоритму; масштабність сценографічного оформлення, що було природним для ХІХ ст., відволікає увагу безпосередньо від танцю. Основні набутки реконструкцій – відновлення втрачених рухів класичного танцю, відкриття купюр.
