U.S.-China Technological Rivalry: from “Arrogance” to Boycott
Authors: Dmitriev S.
Published: December 2020

The spread of the coronavirus pandemic and the slowdown in economic activity in the United States have strengthened the position of supporters of “decoupling” from China. The U.S.-China relations are progressing from “patient integration” to “impatient disengagement”. Escalating research spending, accelerated industrial modernization, and the expansion of China’s high-tech exports have been identified as major challenges to American technology dominance. The fragility of global value chains in cooperative relationships between US and Chinese companies has become particularly evident. The United States plan to free themselves from dependence on China’s innovative technologies and critical materials. Washington’s efforts to revive the country’s manufacturing industry received a new impetus. American TNCs have begun to return some of their enterprises to the USA. The “technological boycott” of China is aimed at causing maximum damage to the development of any competitive business that presents a challenge to American multinational corporations, and to slow down the progressive technological development of the PRC. Equally important are considerations of industrial policy aimed at crowding out competitors. Washington’s protectionist actions led to a reduction in trade and mutual investment and have put American companies targeting Asian consumers in a difficult position. Washington is beginning to fear that Beijing may powerfully respond to the United States with countermeasures that are sensitive to the American military-industrial complex and innovative sectors of the economy. Washington’s aggressive actions are mobilizing China’s efforts to move up the value chain and localize products to achieve self-sufficiency in key technologies. However, the threat remains that protectionism could become a “new normal” not only for U.S.-China relations. The only viable alternative to this scenario may be the joining of efforts of market participants interested in returning to international legal norms of trade.

Bu çalışmanın amacı, lisans programlarında yer alan tarih derslerinde birinci el kaynakların kullanım durumunu tespit etmektir. Nitel veri toplama yöntem ve araçlarının kullanıldığı bu araştırmada betimsel tarama modeli benimsenmiştir. Araştırmanın çalışma grubunu 2016-2017 akademik yılında Atatürk Üniversitesi Kazım Karabekir Eğitim Fakültesi, Atatürk Üniversitesi Edebiyat Fakültesi ve Erzurum Teknik Üniversitesi Edebiyat Fakültesi’nde görev yapan ve tarih derslerini yürüten toplam 27 öğretim üyesi ile bu fakültelerdeki tarih eğitimi anabilim dalı ve tarih bölümlerinin 4. sınıflarında öğrenimlerini sürdüren toplam 70 öğrenci oluşturmaktadır. Araştırmada veri toplama aracı olarak yarı yapılandırılmış görüşme formu ve açık uçlu anket formu birlikte kullanılmıştır. Çalışmada elde edilen veriler içerik analizi ile çözümlenmiştir. Çalışmanın sonucunda öğretim üyelerinin derslerinde kaynakları çeşitli türlerde kullandıkları görülmüştür. Ancak bu kaynakları sınıflarda geleneksel biçimde ele aldıkları, ilgili literatürde gösterildiği üzere üst düzey düşünme becerilerinin geliştirilmesine yönelik pek kullanmadıkları tespit edilmiştir. Buna ek olarak; gerek öğretim üyelerinden gerekse öğrencilerden elde edilen bulgular; birinci elden kaynaklarla ilgili uygulamalı çalışmaların sınırlı kaldığını, öğrenci merkezli etkinliklere pek başvurulmadığını ve öğretim üyeleri tarafından daha çok görsellerinin gösterilip tanıtıldığını ortaya koymuştur. Öğretmen adaylarının aldıkları eğitimin ortaöğretim derslerinde birinci el kaynakları eğitsel amaçlı kullanmak için yeterli olmadığı görülmektedir

Published: December 2020

Bu araştırmanın amacı, 8. sınıf öğrencilerinin görsel ve cebirsel ifadeler konusundaki hata ve kavram yanılgılarını incelemektir. Çalışma gurubunu Afyonkarahisar ilinde sekizinci sınıfta öğrenim gören 120 ortaokul öğrencisi oluşturmaktadır. Veriler basit görsel ve şekil örüntülerini cebirsel ifade etmeyi gerektiren biri çoktan seçmeli 4’ü açık uçlu sorudan oluşan cebir testi ile toplanmıştır. Veriler betimsel ve içerik analizi yapılarak analiz edilmiştir. Araştırma sonucunda cebir geometri ilişkisini kuramayan öğrencilerin cebirsel ifadeleri anlamakta zorlandıkları ve örüntüden cebirsel denkleme geçemedikleri tespit edilmiştir. Ayrıca öğrencilerin basit görsel ve cebirsel ifadelerdeki hataların yanlış cebirsel işlem seçimi, cebirsel ifadelerde parantezi dikkate almama, şekil örüntüsünü yanlış yorumlama ve aritmetik işlem hatasından kaynaklandığı görülmüştür. Aritmetikten cebire geçişi kolaylaştırmak amacıyla cebir öğretiminde somut materyallerden ve görsellerden daha çok yararlanılması önerilir.
Tanzimat Şiiri Örneklerinden Yola Çıkılarak Dönemin Çocuk Algısını Keşfetmek
Authors: OLPAK KOÇ Canan
Published: December 2020

ÇÇocukluk hayatın en önemli süreçlerinden biridir. Bu nedenle psikolojiden sosyolojiye, biyolojiden edebiyata birçok bilimin/ilimin konusu olmuştur. Yetişkin davranışlarını açıklamak için başvurulan en temel kaynak olan çocukluğun nasıl geçtiği de yine yetişkinlerin onlar hakkındaki algısına ve yaptıklarına bağlıdır. Bu algıyı öğrenmek için çocuk edebiyatında yer alan metinlerin takip edilmesi önemli sonuçlara ulaşılmasını sağlar. Çocuk edebiyatı; bilmeceden destanlara, tekerlemeden masallara, romanlardan çocuk dergilerine kadar çok geniş bir alana sahiptir. Ancak duygusal yoğunluğun ve samimiyetin daha fazla gözetildiği şiirlerde dönem insanlarının düşünce ve duygularına ulaşmak daha kolay bir yol kabul edilebilir. Bu nedenle farklı alanlarla hızlı değişimlerin yaşandığı Tanzimat Döneminde oluşturulan edebiyat eserlerinde çocuklar hakkında neler söylendiğine de yine dönemden seçilmiş şiirlerle ulaşılabilir. Çünkü müstakil çocuk edebiyatı Tanzimat Edebiyatıyla ortaya çıkmıştır. Çalışmada, estetik olduğu kadar eğitici olan metinler yoluyla çocukluğun nasıl geçirilmesi gerektiği açıklanırken çocuklara karşı davranışların şekli belirlenmeye ve aktarılmaya çalışılmıştır.
II. Meşrutiyet Döneminde Meclis-i Âyan’da Hukukçu Bir Portre: Yorgiyadis Efendi ve Meclis-i Âyan’da İlk Ceza
Authors: ŞAHİN Gürsoy
Published: December 2020

Bu çalışmanın temel amacı II. Meşrutiyet döneminde Meclis-i Âyan üyesi olarak atanan Nikolaki Yorgiyadis Efendi’nin hayatı, siyasi faaliyetleri ve Meclis-i Âyan’da aldığı ilk cezayı irdelemektir. Yorgiyadis Efendi 1844 yılında Girit’in Galos Kazasında doğmuştur. 1854’ten itibaren Atina ve İstanbul’da eğitim almıştır. Bilahare Almanya’ya giderek hukuk eğitimi görmüş, burada hukuk doktorasını tamamlamıştır. Mahkeme katipliği ile başladığı kariyerinde İstanbul’da Mahkeme-i Ticaret-i Bahriye Reisliği, Mahkeme-i Temyiz-i Hukuk Dairesi üyeliği gibi çeşitli görevlerde bulunmuştur. 28 Ağustos 1907’de atandığı Sisam Beyliği görevinden aynı yılın 26 Aralık tarihinde ayrılmak zorunda kalmış, ardından Şura-yı Devlet üyeliğine tayin edilmiştir. 16 Aralık 1908 tarihinde Meclis-i Âyan üyeliğine atanan Yorgiyadis Efendi 9 Haziran 1915’te ölene kadar bu görevine devam etmiştir.
Rum kökenli olan Yorgiyadis Efendi’nin Türk parlamento tarihinde farklı bir yeri bulunmaktadır. Zira Meclis-i Âyan’ın iki yasama dönemi içinde kınama (takbih) cezası alan tek isimdir. Yorgiyadis Efendi’nin diğer bir özelliği ise Meclis-i Âyan’da bir grup oluşturamayan Hürriyet ve İtilaf Fırkası’nın görüşleri doğrultusunda hareket etmesidir.
Makalede, sıra dışı bir portre olarak nitelendirilebilecek Yorgiyadis Efendi’nin özelikle ceza aldığı Meclis-i Âyan’daki konuşmaları ve tartışmaları değerlendirilmiştir. Çalışmanın temel kaynaklarını Cumhurbaşkanlığı Osmanlı Arşiv Belgeleri ile Meclis-i Âyan ve Meclis-i Mebûsan Zabıt Cerideleri oluşturmuştur.

Published: December 2020

Face aux crises que subit l’élevage et aux questionnements forts de la société vis-à-vis de celui-ci, les prairies permanentes et temporaires pourraient contribuer à fournir une réponse positive et reconnue pour l’élevage de ruminants (bovin, ovins et caprins). L’objet de cet article est de proposer un état des lieux des nouvelles connaissances et des innovations en termes d’outils de gestion des prairies en zone tempérée, au regard de l’évolution des enjeux associées à l’élevage. Les connaissances sur le fonctionnement des prairies et leur gestion ont fortement progressé ces dernières années et ont été particulièrement approfondies pour les prairies permanentes, surfaces prairiales plus complexes à gérer. Leurs intérêts environnementaux sont multiples et confèrent aux prairies de réels atouts. A ces éléments s’ajoutent de forts avantages au regard de la santé des animaux et de la qualité nutritionnelle et organoleptique des produits animaux ayant un impact sur la santé humaine, mais aussi des perspectives intéressantes pour la résilience des systèmes de production face aux aléas climatiques et économiques. Au-delà de leur intérêt économique, ces éléments écosystémiques devraient permettre aux prairies de conforter leur place dans des élevages ruminants durables de demain et acceptables par la société.

The populations of South Australian duck and wader species have recently decreased considerably, but their abundance at Bolivar Wastewater Treatment Plant in metropolitan Adelaide is poorly known. To help assess the importance of this site for ducks and waders, we made 25 trips to Bolivar between December 2018 and July 2020, during most of which time south-eastern Australia was experiencing a long dry period. On each trip, we observed between 11 and 26 species of ducks and waders, with a mean total of 9804 (range 2437–15,653) individuals per trip. At times, we observed several thousand Pink-eared Ducks Malacorhynchus membranaceus, Grey Teal Anas gracilis, and Australian Shelducks Tadorna tadornoides, with occasionally up to 1200 Blue-billed Ducks Oxyura australis and 2000 Hardheads Aythya australis. Several wader species that largely breed in Australia’s semi-arid and arid zones were also observed, including occasionally >1000 Red-necked Avocets Recurvirostra novaehollandiae. Five species of waders that breed in the Northern Hemisphere were also recorded fairly regularly in the summer of both 2018–2019 and 2019–2020, including up to ~2000 Sharp-tailed Sandpipers Calidris acuminata, 2000 Red-necked Stints C. ruficollis and 150 Curlew Sandpipers C. ferruginea. These observations indicate that this wastewater treatment plant is a critically important refuge site for several species of ducks and waders. Every effort should thus be made to maintain this site for the conservation of these species in the future.
Inflation Threshold Effects on Growth in Ethiopia: Evidence from Food and Non-food Sectors
Authors: Tenaw Dagmawe , Demeke Helen
Published: December 2020

Economists have long been interested in examining inflation-growth nexus. Nevertheless, the nature of their relationship and the optimal level of inflation threshold for economic growth have still remained controversial in both theoretical and empirical works. Accordingly, this study investigates the existence of threshold effects of inflation on economic growth in Ethiopia over the period 1975-2018 using a Two-regime Threshold Auto-regressive (TAR) model. The study mainly departs from previous works since it estimates sector-specific inflation threshold level in food and non-food sectors. Our preliminary analyses clearly reveal that inflation in food sector has become more volatile, less-persistent and key contributor to the general inflation as compared to its non-food counterpart. Further, The TAR model results and robustness checks indicate the existence of inflation threshold in a range of 9-10%. In particular, the threshold level for food inflation is 10% and 8% for non-food inflation. In all cases, our results robustly confirm growth-detrimental effects of inflation after the threshold levels. After all, this study suggests the need for considering specific behaviors of food and non-food prices, and implementing appropriate fiscal and monetary policies to bring inflation down to a single-digit level.
Resource Interaction in Smallholder Farms is Linked to Farm Sustainability: Evidence from Indian Sundarbans

Published: December 2020

Shrinking farm size and fragile farm resources pose a significant challenge to the sustainability of small-scale farms. Efficient resource utilization in small-scale farms is crucial to achieving farm sustainability through endogenous mechanisms. However, the precise mechanisms to integrate physical resources to achieve farm sustainability are not very clear yet. By capturing the interaction among farm resources as a network phenomenon, we identify the discrete resource interactions (RIs) in different types of small-scale farms of Indian Sundarbans, which are associated with higher farm sustainability. Thirty-two linkages, 11 reciprocal linkages, 22 triads, and three ‘core elements’ that occurred and cooccurred on highly sustainable farms are found to be critical in achieving farm sustainability. Using the properties of resource interaction networks as explanators of farm sustainability, we anticipate that sustainability in small-scale farms can be achieved by strategically creating new RIs on the farm. However, there may be limitations to such achievement depending on the nature of RI and type of farm. The analytical approach helps to understand the structural basis of sustainability in small-scale farms, and this approach can be used to achieve farm sustainability through the strategic integration of existing farm resources in the smallholder systems.
Preeclampsia: Сardiotonic Steroids, Fibrosis and a Hint to Cancerogenesis

Published: December 2020

Despite prophylaxis and attempts to select a therapy, the frequency of preeclampsia does not decrease, and it still takes the leading position in the structure of maternal mortality and morbidity worldwide. In this review, we present a new theory of the etiology and pathogenesis of preeclampsia which is based on the interaction of Na/K-ATPase and its endogenous ligands including marinobufagenin. The signaling pathway of marinobufagenin involves an inhibition of transcriptional factor Fli1, a negative regulator of collagen synthesis, followed by deposition of collagen in the vascular tissues and altered vascular functions. Moreover, in vitro and in vivo neutralization of marinobufagenin is associated with restoration of Fli1. The inverse relationship between marinobufagenin and Fli1 opens new possibilities in the treatment of cancer: since Fli1 is a proto-oncogene, a hypothesis on suppression of Fli1 by cardiotonic steroids as potential anti-tumor therapeutic strategy is discussed as well. We propose a novel therapy of preeclampsia which is based on immunoneutralization of the marinobufagenin by monoclonal antibodies, which is capable to impair marinobufagenin-Na/K-ATPase interactions.
Theory of Inhomogeneous Calamitic Coulomb Fluids
Authors: Podgornik Rudolf
Published: December 2020

A field theoretic representation of the classical partition function is derived for a system composed of a mixture of anisotropic and isotropic mobile charges that interact via long range Coulomb and short range nematic interactions. The field theory is then solved on a saddle-point approximation level, leading to a coupled system of Poisson-Boltzmann and Maier-Saupe equations. Explicit solutions are finally obtained for a calamitic counterion-only system in proximity of a charged planar wall. The nematic order parameter profile, the counterion density profile and the electrostatic potential profile are interpreted within the framework of a nematic-isotropic wetting phase with a Donnan potential difference.
Climate-Smart Agricultural Practices in Ethiopia: Implications of Mitigation of Greenhouse Gas Emissions: A Review Paper
Authors: Shiferaw Wakshum
Published: December 2020

This paper aimed to assess climate-smart agricultural practices in Ethiopia, discuss the contribution of climate-smart agricultural practices for mitigation of greenhouse gas emissions, and examine determinant factors of climate-smart agricultural practices in mitigation of greenhouse gas emissions. Conservation agriculture, integrated soil fertility management, agroforestry, crop diversification, and improved livestock feed and feeding practices are among the best climate-smart agricultural practices in Ethiopia. Combination of the adoption of climate-smart agricultural practices such as no-tillage increased crop diversity and retaining crop residue on-farm have a mitigation potential of increased SOC in non-flooded crops that change in a significant ton of CO2e ha-1 year-1. In addition, a mitigation potential of CH4 in reduced irrigation of paddy rice farms was also changed in ton CO2e ha-1 year-1. It was found that productivity enhancing interventions in the tropics could reduce emission intensity in dairy systems by up to 0.9 t CO2e per milk. Agroforestry practices and the addition of organic fertilizers on the farm increased mitigation potential of 784093 t CO2e and 193050 t CO2e biomass of carbon and SOC per year respectively. Adoptions of climate-smart agricultural practices are affected by different factors such as farming factors, technology inaccessibility, environmental factors, policy design and social expertise, negative attitudes and motivations of farmers, farmers’ socio-demographic factors, and farmers' socioeconomic factors. To reverse the situation, preparation of targeted climate-smart agricultural practices to areas that are likely to provide the greatest GHG reduction potential and demonstration of these practices to other areas should be encouraged so that other farmers will learn for similar agro-ecologies.

The infections caused by Chikungunya virus (CHIKV), genus Alphavirus, have become a health problem around the world, due to this virus’s widespread occurrence and high morbidity rate and the absence of vaccines or antiviral drugs. In this study, we analyzed a competitive inhibitor of ornithine decarboxylase—an enzyme that is key in the biosynthesis of polyamines (PAs), N-ω-chloroacetyl-L-ornithine (NCAO), which is a possible inhibitor of CHIKV replication because intracellular polyamines participate in the in vitro transcription and translation of CHIKV. NCAO does not have any cytotoxic effect on C6/36 cells even at 1000 μM at 72 h post-exposure. However, in Vero cells, a cytotoxic effect was present above 380 μM at 48 h post-exposure, which was considered when determining the inhibitory effect on viral replication. In this work, we demonstrate that NCAO inhibits the replication of CHIKV in Vero and C6/36 cells in a dose-dependent manner, causing a decrease in the PFU/mL of at least 4 logarithms (p <0.01) in both cell lines. Viral yields were restored by the addition of exogenous polyamines, mainly putrescine. The HPLC analyses showed that NCAO decreases the content of intracellular PAs, even though mainly spermidines and spermines are present in infected cells. NCAO inhibits CHIKV replication by depleting the intracellular polyamines in Vero and C6/36 cells, suggesting that this compound is a possible antiviral for CHIKV infections.

Published: December 2020

Ovarian lymphoma is an infrequent disease, accounting for less than 1% of all non-Hodgkin lymphoma diagnosis. Symptoms include abnormal vaginal bleeding or discharge, abdominal pain, and urinary obstruction due to the large mass. In our case, a 60-year-old woman, underwent a total abdominal hysterectomy and bilateral salpingo-oophorectomy, as she presented with low-grade follicular lymphoma (FL) in both the ovaries, and the left ovary was observed to be enlarged. The tumor is categorized as lymphoma based upon immunohistochemical markers. Computed tomography (CT) scan of the chest, abdomen, and pelvis and bone marrow biopsy are important for the staging of primary lymphoma of the ovary. The first-line chemotherapy regimen includes rituximab, cyclophosphamide, doxorubicin hydrochloride (hydroxydaunorubicin), vincristine sulfate (Oncovin), and prednisone (R-CHOP) for rapidly proliferative non-Hodgkin lymphoma (NHL). Lymphomas with slower growth patterns can be treated with Bendamustine-Rituximab and don’t need aggressive R-CHOP treatment.

Inclusive education is an important part of the general humanitarian attitude to create equal living conditions and self-realization of various members of society. It is important to diversify approaches to inclusive pedagogy. In particular, the need to take into account age differences in the education of children with disabilities, the need to distinguish inclusive tactics depending on the level of education, the requirement to systematize approaches to inclusive pedagogy from its first structural link and to potentially vocational education. In the system of inclusive education, the primary school occupies a prominent place as the first compulsory educational institution. Aim. The purpose of the article is to consider and analyze current trends in inclusive education in primary school. Methods and instruments. The main research methods are the analysis of the regulatory framework (international policy documents), processing of statistical data, study and generalization of recent publications on the topic with an emphasis on the experience of the leading European countries. Results and conclusion. It is established that the main trends in the development of inclusion at the primary school level are: a) shifting away from specialized schools and classes in favor of increasing inclusive classes; b) finding ways to overcome the inequality of funding for inclusive education in European countries and the inequality of the allocation of the budget that is allocated to the financing of inclusive education ( primary schools); c) active support of inclusive education by the world community, development of basic international documents and programs in order to standardize theoretical, practical and technical approaches to inclusion in primary school;  d) finding opportunities to engage in inclusive practices for skilled people with disabilities; e) search for methods of overcoming social and psychological barriers to inclusive education of primary school children; f) a structured approach to inclusive education in primary school; g) development of a single mechanism for initiating inclusive education and monitoring the implementation of the recommendation on inclusive education, determining its effectiveness.Perspectives. Further attention to the trends of inclusive education is quite relevant.We have to understand the current and future vectors of inclusive education in the world. Nowadays, inclusive education becomes a trend and a prerequisite for ensuring the principle of parity in the humanities, ensuring equal conditions for human development.

Objective. To study the state of the breasts in women who undergo assisted reproductive technologies treatment, using modern methods of radiation imaging. Patients and methods. Pre- and prospective examination and analysis of the data of radiation imaging of the breasts of 220 women, having tubal factor infertility in combination with benign mammary dysplasia, who have successful or unsuccessful experience of participation in assisted reproductive technology programmes. The average age of patients was 42.5 years. Assessment points were: breast tissue density according to the findings of ultrasound, mammography and tomosynthesis, presence of clustered microcalcifications, presence of benign dysplastic processes and fibroadenomas of the breasts. Results. In the group of 35–39-year old patients, the most common pathological processes were fibrocystic mastopathy and fibroadenomas. The main diagnostic methods were ultrasound visualization and US-controlled core-needle vacuum-assisted biopsy. In the group of 40–44-year old women, the predominant pathological process was microcalcification clusters alongside high mammographic density. The main diagnostic methods were digital x-ray tomosynthesis and X-ray-guided core-needle vacuum-assisted biopsy. In the group of 45–49-year old women, cases of breast cancer were diagnosed. 12 women in this group had breast implants. Conclusion. Hormonal medication used in assisted reproductive technologies under the protocols of in-vitro fertilization and intracytoplasmatic sperm injection influence the state of the breasts, increasing a risk of developing diffuse benign mammary dysplasias and, quite possible, a risk of developing breast cancer later in life. Key words: breast diseases, assisted reproductive technologies, tomosynthesis, mammotome, clustered microcalcifications

Published: December 2020

In this work, we analyze the effect of the instruction time of the day on student learning in a programming course taught to first-year undergraduate students in an engineering program. A total of 174 students were split into three different sections, each having a different class time. All sections were taught the same material and by the same instructor. It was found that students in the morning and early afternoon sections performed better than the students in the late afternoon section. In all three sections, there is evidence of long-term retention of concepts, which is attributed to the intervention based active learning environment that uses the principles of constructivism. Specifically, the techniques of reinforcement and feedback help with long term retention and avoiding learning of wrong concepts with immediate corrective feedback.

The influence of the internally displaced persons forced migration on the dynamics of regional social and economic security indicators
Authors:   Donetsk State University of Management, Arakelova Inna
Published: December 2020

The processes of forced internal migration, which became significant in 2014 as a result of the armed conflict in the east of the country, caused significant demographic and social changes in the regions performance. Particularly large changes have been taken place in the areas directly adjacent to the joint forces operation zone. The study is devoted to the research of the impact of the described processes on certain aspects of social and economic security of the regions. Impact assessment was performed on the basis of cluster analysis. In particular, the author constructed a neural network such as the Kohonen map. The model divided the neural sample from 25 regions (24 regions and the city of Kyiv) into six clusters according to the level of four indicators of social and economic security. This allowed assessing the impact of forced internal migration on some aspects of social and economic security of the regions. Based on the obtained map, it has been depicted that Donetsk and Luhansk regions, which directly border the joint forces operation zone, had a dramatic increase in the demographic burden and unemployment rate during the study period. The obtained results allowed assessing the impact of the processes of forced internal migration on the dynamics of certain indicators of social and economic security of the territories.
A neural network approach for fundamental investment analysis: a case of Athens Stock Exchange
Authors:   Victoria University, Nor Safwan Mohd , Zawawi Nur Haiza Muhammad ,   University of Malaysia Terengganu
Published: December 2020

This paper explores investment profitability in an emerging European stock market using fundamental analysis enhanced by artificial neural networks. Using a set of accounting-based financial ratios from publicly available data source, we find that these ratios possess useful information in forecasting future stock returns of Athens Stock Exchange (ATHEX) constituent firms. By combining long and short rules, the neurally reinforced fundamental strategy surpasses the unconditional buy-and-hold rule in the holdout subperiod in terms of returns (total and annualized) and risk (volatility, downside volatility and drawdown) measures. Overall results remain consistent even in the presence of trading costs. Our findings suggest that stock prices in Greece do not fully incorporate financial statement information and thus inconsistent with the principle of market efficiency at the semi-strong form.

The authors study how the financing patterns of agricultural enterprises have changed under the influence of the financial system crisis in Ukraine and the United States (US, USA). The indicators of financing patterns, which are traditionally employed in financial management, were used. However, the main financial indicator which is the financial leverage indicator provides distorted results because agricultural lands are not objects of sale in Ukraine, therefore, they are not considered as assets and are not reflected in the balance sheet of enterprises at fair value. The agricultural lands, which are leased by the agricultural enterprises, were evaluated and the financial leverage indicator was recalculated. After the recalculation, the financial leverage indicator was reduced from 1.081 to 0.128 in 2017 (the latest data available by the beginning of 2020 has been applied). The obtained adjusted value of the financial leverage indicator in Ukraine was even lower than the actual value of 0.149 in the USA in 2017. In addition, the integral indicator of debt capital quality was built to characterize the debt capital of the agricultural enterprises. The analysis showed that the financial system crisis in Ukraine influenced negatively on the financing patterns of the agricultural enterprises. Ukraine lagged far behind in terms of key indicators of the financing patterns of the agricultural enterprises compared with the USA. The study showed the significant statistical relationship between the integral indicator of debt capital quality of the agricultural enterprises and the integral indicator of the banking sector component of the financial system in Ukraine, which allowed building the reliable regression model. It means that the financial crisis influences negatively on the quality of debt capital of the agricultural enterprises. One of the main reasons for improper compensation of the negative effects of the financial system crisis on the agricultural enterprises is the absence of a specialized financial system for agriculture in Ukraine (contrary to the USA), which needs to be confirmed in the course of further research.
