Published: November 2019

Limited information is one of major problem in managing shark and ray population in Indonesia. This research aims to demonstrate a cost-effective video approach to quantify the relative abundance of sharks, rays and other megafaunas (morays, turtles and sea snakes) in no-take and open access zones of Nusa Penida Aquatic Conservation Area. Using 116 deployments of baited remote underwater video systems (BRUVs) that deployed in March 2016, we found 162 individual sharks, rays and another megafauna. Three shark species from three families were identified: blacktip reef shark (Carcharhinus melanopterus, n=2), bigeye thresher shark (Alopias superciliosus, n=1) and bamboo shark (Chiloscyllium punctatum, n=10). Bamboo shark are known to have low valueto shark fisher. Five species of rays from 2 families were recorded: blue-spotted mask ray (Neotrygon kuhlii, n=12), mangrove whip ray (Himantura granulata, n=8), blue-spotted ribbon-tail ray (Taeniura lymma, n=4), blotched fantail ray (Taeniurops meyeni, n=2) and manta ray (Manta spp, n=6). We found that the zoning of the Aquatic Conservation Area had no effect on shark abundance. However, shark abundance was different between sites (East and West Nusa Penida). Numbers of lower order predators such as bamboo sharks, stingrays and morays were relatively high, potentially due to the absence of larger sharks. Rays had greater abundance at sites with low current and in deeper water, while morays, turtles and sea snakes varied across site and current intensity. Redefining zoning needed to improve benefits of spatial closure on conserving sharks, rays and another megafaunas population.

A Computational Account of the Mechanisms Underlying Face Perception Biases in Depression
Authors: Soto Fabian , Stewart Rochelle Ann , Hosseini Sanaz , Hays Jason Scott , Beevers Christopher G
Published: November 2019

Here, we take a computational approach to understand the mechanisms underlying face perception biases in depression. Thirty participants diagnosed with Major Depressive Disorder and thirty healthy control participants took part in three studies involving recognition of identity and emotion in faces. We used signal detection theory to determine whether any perceptual biases exist in depression aside from decisional biases. We found lower sensitivity to happiness in general, and lower sensitivity to both happiness and sadness with ambiguous stimuli. Our use of highly-controlled face stimuli ensures that such asymmetry is truly perceptual in nature, rather than the result of studying expressions with inherently different discriminability. We found no systematic effect of depression on the perceptual interactions between face expression and identity. We also found that decisional strategies used in our task were different for people with depression and controls, but in a way that was highly specific to the stimulus set presented. We show through simulation that the observed perceptual effects, as well as other biases found in the literature, can be explained by a computational model in which channels encoding positive expressions are selectively suppressed.
Dispositional Individual Differences in Cognitive Effort Investment: Establishing the Core Construct
Authors: Kührt Corinna , Pannasch Sebastian , Kiebel Stefan J. , Strobel Alexander
Published: November 2019

It is commonly assumed that individuals tend to avoid effort, be it physical or cognitive. Yet, recent evidence suggests that individual differences exist and that personality traits related to the willingness to invest cognitive effort in goal-directed behavior are associated with experimental measures of cognitive effort investment. The personality traits need for cognition (NFC) and self-control were found to be related to behavioral measures of effort discounting and demand avoidance, respectively. Given that NFC and self-control are only moderately related, this evidence raises the question whether these associations are specific for these traits or whether they reflect a common core that these traits both involve cognitive effort investment. If so, the common core of both traits might be related to behavioral measures of the avoidance of cognitive effort in a more systematic fashion. Thus, the present study aimed at specifying a core construct of cognitive effort investment that reflects dispositional differences in the willingness and tendency to exert effortful control. Therefore, we conducted an online-study (N = 613) with questionnaires related to cognitive motivation and effort investment including the NFC and the self-control scale. Our findings support the hypothesized correlations between the assessed traits, where the relationship of NFC and self-control is specifically mediated via an aspect that can be conceptualized as goal-directedness. We found that a hierarchical factor model of cognitive motivation and effortful self-control can explain the shared variance of these two first-order factors by a second-order factor of cognitive effort investment. These findings are backed up by results of an independent second sample (N = 244). Taken together, our results integrate currently only loosely related research strands on cognitive motivation and self-control and provide a basis for further experimental research on the role of dispositional individual differences in goal-directed behavior.
GAMING DISORDER TEST - DRAFT
Authors: Soraci Paolo
Published: November 2019

Le precedenti ricerche sul disturbo da gioco (GD) hanno evidenziato importanti ostacoli metodologici e concettuali derivanti dall'eterogeneità della nomenclatura e dall'uso di strumenti psicometrici non standardizzati per valutare la gravità di questo fenomeno questo fenomeno. Il recente riconoscimento del GD (gaming disorder) come disturbo della salute mentale e dipendenza comportamentale dall'Organizzazione mondiale della sanità (OMS) nell'11a revisione della classificazione internazionale delle malattie (ICD-11) apre diverse nuove possibilità per studiare ulteriormente le implicazioni psicosociali e di salute mentale a causa del gioco eccessivo. Tuttavia, prima che ulteriori ricerche sulla GD possano essere condotte in modo affidabile e all'interno di un solido contesto interculturale, dovrebbe essere sviluppato uno strumento psicometrico standardizzato valido e affidabile per valutare il costrutto definito dall'OMS. Lo scopo di questo studio era di sviluppare una versione adatta al contesto Italiano del Gaming Disorder Test (GDT) , che si propone essere una breve misura standardizzata di quattro item per valutare l'eventuale gravità del GD e per esplorare le sue proprietà psicometriche tenendo conto della differenza culturale.

Published: November 2019

In the arid central zone of the Republic of Kalmykia, one of the limiting factors that affects spring barley productivity is the soil moisture content during a vegetation period. The paper discusses the results of a long-term research of zoned spring barley varieties of various breeding institutions in the experimental field of the KRIA named after M. B. Narmaeva, a branch of the FSBSI “PAFRC RAS” to study the effect of instability of soil moisture in a vegetation period on their productivity and especially in the period of grain filling. Field trials were carried out according to the Methods of State Variety Testing of agricultural crops and Methodology of a field trial. In the course of the studies it was found that in arid years the variety “Shchedry” formed a larger yield than that of other zoned varieties. Moreover, in the wet years of 2016 and 2017 the variety “Shchedry” productivity was inferior to the varieties “Prerii” and “Strannik” on average. It has been revealed that in conditions with uneven precipitation in different years, June precipitation has a decisive effect on spring barley productivity in the central zone of the Republic of Kalmykia.

Published: November 2019

There have been presented study results of the spring durum wheat varieties grown in the southern forest-steppe area of the Omsk region on kernel hardness. The objects of research were the varieties of ecological variety testing conducted by various Russian and Ukrainian scientific institutions. The study was conducted in the period from 2003–2015. Experimental plots of 10 m2 were placed in 4 sequences. The varieties were sown in weedfree fallow. The soil of the experimental plot was weakly leached blackearth (chernozem), medium humus (6.2%), and loamy. The sowing date is 14–15 of May, the sowing rate is 4.5 million of germinated kernels per ha. The average hardness index in 2003–2015 was 70.1%. The varieties varied from 66.0 (the variety “Svetlana”) to 74.6% (the variety “Saratovskaya zolotistaya”). The differences between maximum and minimum were 8.6%. The variation through the years was from 51% to 92%, from 21% (the varieties “Angel”, “Omsky korund”) to 34% (the variety “Saratovskaya zolotistaya”). The calculated coefficient of variation showed that the variability degree ranged from little to medium. Coefficients of variation varied from 9.3% (the variety “Angel”) to 14.3% (the variety “Bezenchukskaya 182”). According to S. A. Eberhart, W. A. Russel the stability index indicates a lower variability of the varieties “Angel”, “Omsky korund”, “Altayskaya niva”, “Nik”, “Kharkovskaya 23”, “Tavolga”. The value of the regression coefficient (bi) for kernel hardness ranged from 0.77 to 1.23. The varieties “Voronezhskaya 9”, “Elizavetinskaya”, “Altayskaya niva”, “Omskaya stepnaya” and “Bezenchukskaya stepnaya” turned to be most responsive to the conditions (according to the Eberhart – Russell test). The varieties “Angel”, “Aleyskaya”, “Zarnitsa Altaya” had a weak reaction to the environmental conditions. There has been identified phenotypic correlation between the trait and productivity, 1000-kernel weight, nature weight, gluten quality, pasta color. The correlation between these traits is positive, on average r = 0.30–0.440.

Published: November 2019

The current study gives the results of 2-year field trails which tested three protection systems for the spring barley variety “Yaromir” to improve the phytosanitary condition of sowings and to increase productivity. It has been established that the studied protection systems effectively protected spring barley from harmful organisms from sprouting to harvesting. With a total number of weeds of 80 pcs/m2 in 2017 the effectiveness of the herbicides was 91–94%; and with a total number of weeds of 72 pcs/m2 in 2018 the effectiveness of these preparations was 92–95%. There has been evaluated fungicides’ impact on the development of dark brown and net spots. The effectiveness of the preparations through study years ranged from 89 to 92% for dark brown spots and from 80 to 85% for net spots. As a result of the analysis of spring barley productivity, it has been revealed that under the effect of protection systems there has been obtained an additional grain yield of 1.42, 1.46, 1.44 t/ha in 2017 and 1.29, 1.33, 1.26 t/ha in 2018. The analysis of the economic efficiency of the studied protection systems has shown that in 2017 a conditionally net income ranged from 1,000 to 3,650 rubles/ha, in 2018 it ranged from 5,780 to 7,636 rubles/ha, when 1 ton of spring barley grain cost 5 thousand rubles in 2017, and 9 thousand rubles in 2018.

Published: November 2019

Background: The majority of new hepatitis C (HCV) cases occur among people who inject drugs. In recent years, multidisciplinary models of HCV treatment have emerged that demonstrate successful treatment outcomes for this population, as well as broad positive individual- and system-level impacts. Our objective was to evaluate changes in health care use among a cohort of people living with HCV before and after engagement with one such program. Methods: Program data were uniquely linked to provincial health administrative databases. Rates of emergency department (ED) visits and hospital admissions of clients from 2011 through 2015 ( N = 103) were evaluated using linkages with administrative data for the 2 years before and after program initiation. Data were evaluated using negative binomial regression models with a covariance structure to account for within-individual correlations. Results: Of participants, 72.8% were men (mean age 47 years), and 38% experienced high rates of physical and mental health comorbidity (Aggregated Diagnosis Group score ≥10). Female clients had significantly fewer ED visits 2 years after program initiation (5.04 versus 3.12; risk ratio [RR] 0.61 [95% CI 0.44% to 0.86%]). ED visits for infectious diseases and soft tissue injury were significantly lower for the cohort overall (RRs 0.58 0.51 [95% CIs 0.35% to 0.95% and 0.29% to 0.90%], respectively). Conclusion: Co-locating HCV treatment within comprehensive primary care and harm reduction services appears to have benefits beyond HCV, including a reduction in ED visits among women and a decrease in ED visits for soft tissue infections for all participants.
Chain-Gang Gothic: The Colonel’s Dream and the Spectacular Terrors of State Punishment
Authors: Haslam Jason
Published: November 2019

Charles Chesnutt’s 1905 novel The Colonel’s Dream meditates on the structures of spectacle and ignorance that create a continuity of white privilege and white supremacy from North to South, and on the role that the nascent prison-industrial complex plays in that process. Chesnutt uses occasional gothic irruptions within his otherwise realist and sentimental form to show how “hidden” and spectacular punishments, legal and extra-legal state violence, all function to impose a purposeful ignorance of their very existence: punishments, their spectacular renditions, and the public’s turning away from them combine to become a structuring aporia that maintains white supremacy in the face of democratic resistance.
Violent (Non-)Labour: On the Social Reproduction of the Clone in Carola Dibbell’s The Only Ones
Authors: Bellamy Brent Ryan
Published: November 2019

In a reading of Carola Dibbell’s debut novel The Only Ones (2015), this article deploys the term “(non-)labour” in two senses: one is a cheeky description of cloning as the activity of reproducing human beings without the traditional sense of labour as delivery of an infant, and the other draws on Marxist-feminist accounts of care work as the remunerated or unremunerated, though structurally necessary, labour required to reproduce the workforce. Dibbell’s novel presents a version of the human as a worker always already embedded in social relations and reveals the violence that thoroughly saturates the biomedical industry. Yet, as this article argues, violent labour is most evident when characters do work that has too long been imagined outside the sphere of value production. The Only Ones illustrates the impossibility of producing value without labour, violent or otherwise; it directs readers to consider the unlikely places where we already give away our work for free.
“It’s Still Real to Me”: Contemporary Professional Wrestling, Neo-Liberalism, and the Problems of Performed/Real Violence
Authors: Jansen Brian
Published: November 2019

Beginning from the premise (vis-à-vis wrestler-turned-scholar Laurence de Garis) that professional wrestling scholarship has historically overlooked the embodied, physical dimension of the form in favour of its drama, and reflecting on a series of professional wrestling story-lines that have blurred the lines between staged performance (“kayfabe”) and reality, this article suggests that the business of professional wrestling offers a vivid case study for the rise and dissemination of what political theorist Wendy Brown calls neo-liberal rationality: the dissemination of the market model to every aspect and activity of human life. Drawing on Brown’s work, the language of World Wrestling Entertainment (WWE) contracts, and professional wrestling’s territorial history, this article argues that contemporary story-lines in professional wrestling rationalize, economize, and trivialize the form’s very real violent labour, even rendering audiences complicit in said violence—while serving also as a potent vehicle for understanding the metaphorical (and sometimes literal) violence of neo-liberal rationality more broadly.
A systemic perspective on children’s well-being in military families in different countries
Authors: Kasearu Kairi , Olsson Ann-Margreth E.
Published: November 2019

Introduction: Children are influenced by different environments – home, friends, school, community, society, and the existence and availability of various services – and child well-being is the outcome of the interrelationships between the child and these environments. The military is one of the environments that shapes the well-being of children in military families, and the environments interact with each other. Methods: Our main assumption is that the effect of military environment on child well-being may vary in different societies depending on the general social security system. We describe how the military children’s well-being is embedded in military systems, which in turn is embedded in welfare state. The main question is how the well-being of children from military families varies across countries and how much variation can be explained by the interplay between military systems and different welfare regimes. Results: We begin by describing the differences in welfare states and military systems, and then give a short overview of children’s well-being in the context of different welfare regimes (e.g., availability of public child care, health care, and access to education and extracurricular activities). Discussion: Next, we look at the interplay between the military and welfare regimes and, finally, we show how the well-being of military children is supported across countries by their different welfare regimes.
Recommendations for measurement of well-being
Authors: Bühler Antje
Published: November 2019

Introduction: Measurements of child well-being in the military context through cross-national surveys must allow assessment of both (1) indicators for vulnerability and resilience in such children, and (2) factors leading to program success across the different NATO members. Methods: This review identifies psychometric properties (including validity, cross-cultural validation, sensitivity [SE], and specificity [SP] of each measure for various cutoffs for referral for psychiatric evaluation) as well as feasibility (cost-efficiency, time needed for filling in the questionnaire, language availability, and costs for its use). The measures included are four generic health-related quality-of-life measures (PedsQL 4.0, KIDSCREEN-52, DCGM-37, and KINDL-R) and four screening measures for mental health: the Achenbach System of Empirically Based Assessment (ASEBA), the Child Health Questionnaire (CHQ), the Pediatric Symptom Checklist (PSC), and the Strengths and Difficulties Questionnaire (SDQ). Results: High SE and SP values (0.70) for the screening instruments occurred in only 30%–55% of the studies reviewed. Cross-cultural validation and content validity are best covered by the KIDSCREEN-52, which is the dominant HRQOL instrument in Europe. The HRQOL instrument mostly used in the United States is the PedsQL. Discussion: Although there is no gold standard, the combination of a mental health screening instrument (the SDQ) with a HRQOL instrument (the KIDSCREEN-52), is recommended due to their complementary advantages on the evaluation criteria. Future comparability of items banks, such as those in the KIDSCREEN-52 and the PedsQL, is aimed for by the United States based PROMIS project.

The main purpose of this study is to comprehend the effects of cryomilling (CM) time on dry sliding wear behaviour of 10 wt.% TiB2 reinforced Al-12.6 wt.% Si metal matrix composites (MMCs). The MMCs were synthesised via sequential milling (mechanical alloying + cryomilling) and pressureless sintering. Indentation tests performed at a maximum load of 200 g showed that the Young's modulus and hardness of the composites increased up to 20 min of CM time. The effects of CM time and load on the composites were examined based on their tribological properties. Based on the results, the 4 h mechanical alloyed (MA'd) and 30 min CM'd sample showed the lowest wear rate under the normal load of 1 N, with its wear mechanism being predominantly oxidative. However, for the normal load of 4 N, the lowest wear rate was found in the 4 h MA'd composite, in which the dominant wear mechanism was abrasion.
Effects of Ni and Al on the Cu-precipitation in ferritic Fe–Cu–M (M = Ni or Al) alloy
Authors: Wang Haiyan , Wang Chengmeng , Gao Xueyun , Ren Huiping
Published: November 2019

The effects of nickel and aluminum on the precipitation of copper-rich precipitates in Fe–Cu ferritic alloy were investigated by combining experiments and first-principles calculations. With the addition of Ni and Al, the Fe–Cu–
M (M = Ni or Al) alloy reaches the peak ageing condition earlier than the Fe–Cu binary system during ageing at 500 °C. The transmission electron microscopy results indicate that the average sizes of the copper-rich particles in the Fe–Cu–Ni and Fe–Cu–Al alloys are smaller than that in the Fe–Cu alloy, while the density numbers of the former are larger than the latter. The interactions of the copper atom with nickel and aluminum atoms are all attractive in the first nearest neighbor shell. These attractions increase the local concentration of nickel and aluminum around copper and promote the clustering of solutes, consequently increasing the nucleation rate of Cu-rich precipitates.

Authors: Kovaľová Jana , Ondrijová Ivana , Ratnayake Kaščáková Dagmara
Published: November 2019

Personal selling has its own specifics and allows sellers to interact directly with the customer. The aim of the proposed paper is to find out statistically significant differences in the perception factor affecting personal selling from the customer’s perspective in the context of gender differences. A differential analysis was conducted on the sample of 243 respondents (112 male customers and 131 female customers); on the basis of the data obtained by means of an original methodology for detecting the factors influencing the customers’ perception of the sellers in personal selling. Gender differences in customer perceptions were confirmed in six items of observed factors: seller’s image, seller’s willingness and empathy, and his or her communication skills. The results of the analysis confirmed the existence of statistically significant differences between the male and the female in their perception of the sellers. Based on these results it may be concluded that, male and female differently view the seller’s image, his or her willingness and empathy towards customers, as well as its communication skills.
SUSTAINABLE POST-CRISIS CAPITAL MARKET RECOVERY – THE CASE OF EURO STOXX 50
Authors: Tsenkov Vladimir , Mirchev Kiril
Published: November 2019

In the context of the last global financial crisis of 2008 and the subsequent post-crisis recovery of international capital markets, the question of the sustainability of that recovery process has been raised. To test that we use the presence and the magnitude of manifestation of market phenomena called volatility paradox. This paradox raises the question whether its presence in the conditions of the sustainable ascending market trend during the post-crisis recovery is not a signal marking the potential for a new forthcoming financial crisis. Studying the periods before and after the 2008 global financial crisis can give us a pattern market dynamics of volatility paradox manifestation in the pre-crisis period which can be traced out in the post-crisis period. If the existence of volatility paradox is possible, it should be seen in the pre-crisis period up to 2008. Its power of manifestation during this period should serve as a benchmark for verifying the post-crisis VP, both as an existence and as a size of manifestation compared to the demonstrated until 2008. The empirical results show that the market dynamics of the EURO STOXX 50 index proves the existence of volatility paradox, both in the pre- and the post-crisis period. For the same two periods for the shares included in the EURO STOXX 50 the existence of volatility paradox is not detected. Moreover, the shares of the EURO STOXX 50 index show higher market efficiency in the context of EMH in comparison with the index itself. The empirical research was made using market dynamics of the EURO STOXX 50 index and the shares it’s incorporated in the period 2005 - 2017. In this research, we use the daily returns of the explored index and shares whose volatility was modeled by TGARCH models.
THE MATHEMATICAL MODELLING METHODS APPLYING TO ESTIMATE THE PIPELINES TECHNICAL STATE AND ENVIRONMENT SITUATION

Published: November 2019

In the context of providing trouble-free operation of oil and gas pipelines and preventing possible negative impacts on the environment, the issues of constructing an integrated mathematical model for assessing the technical condition of pipelines and the impact of emergency situations on the state of the environment in the course of hydrocarbon leakage are considered. The model of the evaluation of the stress-strain state of the pipeline according to the data on the displacement of surface points for the above ground and underground sections is given by constructing the law of motion of the site by known displacements of a certain set of surface points using assumptions about the type of deformation of the sections and reproduction of the deformations and stresses tensors components   on the basis of different models of deformed solid body.

The specified model does not require information on the whole complex of forces and loads acting on the investigated object during operation. The flow model has been refined in a pipeline with a violation of its tightness by recording a special type of boundary conditions for a Navier-Stokes equation system in a two-dimensional formulation and developing an original method for its solution on the basis of the finite difference method. In the article the stability conditions of the proposed numerical schemes on basis of the spectral sign of stability are presented. In order to assess possible negative impacts on the environment, a model of propagation of matter at its leakage from the pipeline was developed by solving two-dimensional diffusion equations taking into account the variables and different types of boundary conditions that take into account the number of sources of pollution and their intensity. The results of computations based on computational algorithms implemented by these models and graphic material illustrating these calculations are presented, peculiarities of distribution of harmful substances in the environment near the pipeline are analyzed. Directions of further researches for successful practical realization of the offered models are established.
Improving Food Supply throught Increasing Local Production in Azerbaijan
Authors: Tamrazov T. H.
Published: November 2019

Research reviews and accumulated experiences show that irrespective of the branch of agriculture, its main production means are soil.The output of agricultural products and the development of different types of farms depend on the use of soil and its fertility. Azerbaijan has large areasof fertile lands that can produce high yields of agricultural plants.The purpose of the research is to investigate the sources and factors of food security that are of particular importance for ensuring food security of Azerbaijan and meeting the needs of the population in foodstuffs. The current state of food production in Azerbaijan, ways to improve food supply, and food market problems are investigated. Statistical data on the output of cereal grain products, legumes, potato, vegetables and melons, fruit and berries over 2003–2017 are given. The self-sufficiency and import dependence of Azerbaijan in plant products are estimated. The statistical analysis shows that Azerbaijan is still unable to meet the demand for basic food products through their domestic production; the share of imports of grain, grain legumes, vegetable oils, milk and dairy products in the total consumption remains to be high. This means that the positions of foreign producers in the domestic agricultural and food markets have been strengthening compared with the local producers’ positions in respective product segments. Another problem is related with the economic efficiency in the agricultural sector, including more efficient use of land, material and technical means, dissemination of agricultural innovations, intensification of production processes. Recommendations on optimization of food supply and achievement of food safety in Azerbaijan are given.
Analysis of the State and Trends of Ukraine’s Foreign Trade with the EU
Authors: Bulakh Т. M. , Ivashchenko О. A. , Plakhotnikova L. O.
Published: November 2019

Presently, Ukraine is highly integrated into the global economic area and maintains foreign trade relations with more than 200 countries. The European Union (EU) is one of the most important foreign trade partners of Ukraine.
Therefore, the analysis of Ukraine’s foreign trade is important for taking effective management decisions and promoting reasonable changes in the economic policy.
The article analyzes the state and trends of Ukraine’s foreign trade with the EU. Its features and dynamics are revealed. The changes in the structure of exports and imports of Ukraine after the signing of the Free Trade Agreement are as follows: export values reaching the pre-crisis level of 2014; the sustained dominance of agricultural and food industry products; the commodity structure of exports could be diversified; imports of goods to Ukraine from the EU in 2012–2017 decreased at a slower pace than the total imports of goods to Ukraine; after a negative trend in 2012–2015, the imports increased by 3658.5 million USD in 2017, signaling that the imports to Ukraine from the EU were recovering at a faster pace than the Ukrainian exports to the EU; the balance of foreign trade in goods between Ukraine and the EU for the period of the study was negative.
Measures to improve the development of foreign trade of Ukraine in the context of deepening European integration processes are proposed: to increase the support for national producers;  to intensify export cooperation with the EU member states with which Ukraine has a negative balance; to attract exporters from non-EU countries to locate production facilities on the territory of Ukraine with the prospects of their exports to European markets; to introduce uniform standards of certification and standardization of products in Ukraine; to develop a strategy to increase exports of nationally produced goods and services to EU markets and reduce imports to Ukraine; to intensify cooperation with the EU on issues of import substitution in Ukraine.
The Role of Pricing in Taxation of Business Enterprises
Authors: YURCHENKO O. , SVYRYDA О.
Published: November 2019

The problem of pricing is elaborated with respect to setting the tax base for calculating tax obligations (taxes and duties) assessed and paid by business enterprises by the general tax system. The role of the regular market price when calculating the tax base for national taxes (profit tax, value added tax, excise tax and tax on incomes of physical persons) is highlighted.
It is shown that valuation of assets (property rights) is the process of estimating their cost on the date of valuation by the established procedure. The valuation can be performed by entities charged with valuation (legal entities, physical persons – entrepreneurs, state power bodies or local power bodies). Subject to valuation are assets (movable and immovable) and property rights (e. g. intellectual property rights, rights for use of nature resources etc.). The cases of obligatory expert valuation of assets are clarified in the course of the study; the valuation phases are substantiated in conformity to the national standards on valuation of assets and property rights.
The notion of transfer pricing, occurring in time of transactions involving residents and non-residents that are subject to control by tax bodies in order to combat minimization of income tax, is defined. Economic transactions with a non-resident counterparty are identified as controlled ones by a payer of profit tax, when their result has no effect for a taxation object. An economic transaction will be identified as a controlled one, when it complies with two criteria set by the Tax Code of Ukraine: cost criterion (the volume of annual income and the volume of transactions with a counterparty) and status criterion (what is non-resident, whether or not it is related with a Ukrainian tax payer, where it is registered, what is its organizational and legal form, whether or not it pays profit tax and by what rate). The controlled transactions are subject to audit for the compliance of their prices with “arm’s length” principles, with the possibility of adjusting a transaction price for purposes of profit taxation in case of noncompliance.    
International and national law establishes five main methods for price determination in the controlled transactions. The choice of method and texted party depends on the essence of transaction and the character of its parties’ interactions. The article gives a description of methods for calculating transfer prices used by tax bodies for auditing the correctness of estimated profit tax in the controlled transactions. The authors believe that the top one is the method of comparative non-controlled price, because it can be used when performing transactions on sales of goods with mass-scale demand, for which it is easier to find the data on analogous transactions of other companies on the commodity market and compare the conditions of such economic transactions.

The article describes the practical experience in organizing the first All-Ukrainian Olympiad on Economic Analytics and Statistics, aiming to improve the quality of professional training, increase the students’ interest to in their chosen profession and create conditions for students to acquire the necessary professional skills and abilities, and gain experience in educational and professional activities. The assessment of the foreign labor market for specialists in Statistics / Analytics / Finance, allowing to determine the relevance of the profession in the near future, is given. A review of the competencies of a statistics analyst, acquired by future specialists in domestic higher education institutions, is made. It is emphasized that formation of the professional competencies cannot be confined to individual disciplines or educational programs; it requires the conditions for  the effective influence of educational technologies, methods, organizational forms, learning environments, including the participation of students in intellectual competitions and Olympiads.

For understanding the structure and specificity of tasks at the first All-Ukrainian Olympiad on Economic Analytics and Statistics, examples of the tasks simulating various aspects and components of an analytical study are given. The results shown by the students participating in the Olympiad are analyzed in comparison with the current requirements to the professional competencies in analytics and statistics. The conclusion about the diagnostic function of Olympiad is made.

The link to the web-site where the Olympiad materials are displayed, allows for using the innovative approaches to lecturing in higher educational institutions as part of the academic program for economic analysts. The current trends in support of gifted students are outlined, and proposals are made on how to improve the effectiveness of student Olympiads in Economic Analytics and Statistics.

Measures for the potential implementation of “social lift” system for young statistics analysts are highlighted. It is stressed that the training of students for Olympiads can be a means elevating their professional and intellectual level, motivating their self-organization and self-realization, and increasing their overall statistical education.  

Further research will focus on feasibility studies and proposals related with adoption of new professions dealing with statistical analytics.

Background: Breastfeeding reportedly reduces the overall frequency of infections. Respiratory syncytial virus (RSV), the most common respiratory pathogen in infants, involves recurrent wheezing and has a pathogenic mechanism related to airway structural damage.Purpose: This study aimed to investigate whether breastfeeding has a beneficial effect against RSV-induced respiratory infection compared to formula feeding among infants in Korea.Methods: We retrospectively reviewed the medical records of infants under 1 year of age who were admitted with RSV infection between January 2016 and February 2018 at the department of pediatrics of 4 hospitals. We investigated the differences in clinical parameters such as cyanosis, chest retraction, combined infection, fever duration, oxygen use, oxygen therapy duration, intensive care unit (ICU) admission, and corticosteroid treatment of exclusive breast milk feeding (BMF), artificial milk formula fed (AMF), and mixed feeding (MF) groups.Results: Among the 411 infants included in our study, 94, 161, and 156 were included in the BMF, MF, and AMF groups, respectively. The rates of oxygen therapy were significantly different among the BMF (4.3%), MF (8.1%), and AMF (13.5 %) groups (P=0.042). The odds ratios (ORs) for oxygen therapy was significantly higher in the AMF group than in the BMF group (adjusted OR, 3.807; 95% confidence interval, 1.22–11.90; P=0.021). The ICU admission rate of the BMF group (1.1%) was lower than that of the MF (3.5%) and AMF (4.5%) groups; however, the dissimilarity was not statistically significant (P=0.338).Conclusion: The severity of RSV infection requiring oxygen therapy was lower in the BMF than the AMF group. This protective role of human milk on RSV infection might decrease the need for oxygen therapy suggesting less airway damage.
