Visual images of beauty of the word in the Persian poetry of XVI - the beginning of XVIII century: the Indian style and painting by word
Authors: Reisner Marina L.
Published: March 2020

The article is devoted to the problem of changing stylistic paradigm in the Persian poetry of XVI-XVII centuries and reflection of this process in self-consciousness of outstanding authors of the period. Parallel with preserving stable norms of traditional poetics literary practice demonstrates flexibility and forms new range of popular poetic strategies. New aesthetic criteria if ideal poetic language, expressed with epithet ‘colourful’ ( rangin ), appears alongside with criteria of previous period, expressed with epithet ‘sweet’ ( shirin ) and step by step gets leadership. Lyric poetry ( qhazal ) of three famous authors of the period of formation and golden age of Indian style served the object of analyses. The phenomena of visualization of imagery connected with perfect poetic language illustrated by examples of ‘Poet and Poetry’ motifs located in ‘frame text’ in end of the qhazal . These motifs serve one of the regular contexts of author’s name ( takhallus ) and show author’s attitude to his creation, including stylistic preferences. Refinement of poetic fantasy being declared basic condition of creating perfect poetry described visually as coiling lasso, poetry itself as flourishing garden, fountain or European house decorated with painting. Such characteristic of word creation has analogies in the works of Baroque style theorist Giambattista Marino (1569-1625).
Eric Voegelin's History of political ideas. The bones of contention of the political animal
Authors: Castro-Henriques Mendo
Published: March 2020

The History of Political Ideas by the German-American philosopher Eric Voegelin (1901-1985) is a monumental work of around 2,600 pages. It remained unpublished during his lifetime, and it came to light through the American edition (1997-1999) and the now completed Portuguese edition (2012-2018). Being the author of the first world edition of an abridged version of the History of Political Ideas ; the translator of the first three volumes of the 2012-2018 Portuguese edition; and the author of The civil philosophy of Eric Voegelin (my 1990 Ph. D diss.) I consider that the History of Political Ideas challenges the present climate of opinion: it subverts the dominant corrosive forces of moral relativism, intolerant neo-positivism, end-of-history obsessions, postmodernist deconstructions, agnosticism, nihilism, new age religions, and the all-pervasive ideology of money. Eric Voegelin achieves all this leading his readers from Antiquity to Modern Age. His monumental work begins with the “spiritual disintegration” of the Greek world, after the peak of Plato and Aristotle, a disintegration that ushered a long process of transition in the self-understanding of man in the Mediterranean world. The series goes through Middle Ages , R enaissance and Reformation as Voegelin analyzes the collapse of imperial Christianity, which led to the rise of autonomous reason and sectarian revolts that reached full development in later centuries. A new form of modern human consciousness replaced the Christian understanding of a divinely created closed cosmos. The collection ends - in a suspensive way - with “The Crisis and the Apocalypse of Man” focused on thinkers such as Comte, Bakunine and Marx; although they experienced true epiphanies, they become self-obsessed to the detriment of the world to which they refer. Such “Apocalypse of Man” must now be challenged, albeit with methodologies and hermeneutic principles other than those that Voegelin himself abandoned some decades ago.
Crossborder tourist mobility in borderland: theoretical and practical aspects
Authors: Stepanova Svetlana V.
Published: March 2020

The socio-economic transformations of Russia as well as the change in the functions of state borders in the context of integration processes in the global society, along with the change in the perception of the tourism at the level of government, business and society, served as a prerequisite for the tourist vector of development of border areas. The increasing competition for the financial resources of tourists contributes to a change in the socioeconomic space of the territories, which is most noticeable in the borderlands. The article substantiates the importance of cross-border tourist mobility in the development of the borderland. Depending on the chosen focus of attention (development of the local community, economic and spatial development of the territory), the benefits and risks for the socio-economic development of the territory are different for the both sides of the border. The cross-border tourist mobility is considered on the example of the Russian-Polish and Russian-Finnish borderlands. A significant asymmetry of mutual cross-border tourist flows has been revealed. This tendency will increase thanks to the actively pursued marketing policy of the business of neighboring countries to stimulate the entry flow of Russian citizens with tourist purposes.

Authors: KOCA Nizameddin , SEFEROGLU Meral
Published: March 2020

Introduction: In the general population, the rate of older people seeking healthcare would increase. Understanding underlying factors that determine positive and negative attitudes towards the elderly is essential to give better healthcare.Methods: One-hundred and sixty-nine physicians participated in the study. Participants answered an online questionnaire consists of sociodemographic information, and the University of California at the Los Angeles Geriatrics Attitude (UCLA-GA) scale to evaluate the attitudes towards the geriatric population.Results: The attitude towards the elderly by internist, neurologist, and psychiatrist was comparable. Relationship with positive attitude and specialties, gender, age, marital status, duration of specialty expertise, and having geriatrics education and monthly followed-up elderly patients was not significant. The positive attitude was significantly related to having an elderly relative.Conclusions: In our study, although neurologists received more geriatric education, and mostly seen inpatient and outpatient patients, their attitudes towards geriatric patients were similar to psychiatry and internal medicine specialists. In addition, we observed that positive attitudes in elderly patients were significantly associated with having a relative over 65 years old. Education curriculum should include programs increasing the exposure to healthy older people may increase positive attitude rates. The organization of working programs should be carried out considering the necessity of a long time to evaluate the elderly.

Generalized Hirano inverses in Banach algebras
Authors: Chen Huanyin , Sheibani Marjan
Published: March 2020

Let A be a Banach algebra. An element a ? A has generalized Hirano inverse if
there exists b ? A such that b = bab, ab = ba, a2-ab ? Aqnil. We prove
that a ? A has generalized Hirano inverse if and only if a - a3 ? Aqnil, if
and only if a is the sum of a tripotent and a quasinilpotent that commute.
The Cline?s formula for generalized Hirano inverses is thereby obtained. Let
a, b ? A have generalized Hirano inverses. If a2b = aba and b2a = bab, we
prove that a + b has generalized Hirano inverse if and only if 1 + adb has
generalized Hirano inverse. The generalized Hirano inverses of operator
matrices on Banach spaces are also studied.

OBJECTIVE

To determine the incidence of and factors associated with an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 in people with diabetes.

RESEARCH DESIGN AND METHODS

We identified people with diabetes in the EXamining ouTcomEs in chroNic Disease in the 45 and Up Study (EXTEND45), a population-based cohort study (2006–2014) that linked the Sax Institute’s 45 and Up Study cohort to community laboratory and administrative data in New South Wales, Australia. The study outcome was the first eGFR measurement <60 mL/min/1.73 m2 recorded during the follow-up period. Participants with eGFR < 60 mL/min/1.73 m2 at baseline were excluded. We used Poisson regression to estimate the incidence of eGFR <60 mL/min/1.73 m2 and multivariable Cox regression to examine factors associated with the study outcome.

RESULTS

Of 9,313 participants with diabetes, 2,106 (22.6%) developed incident eGFR <60 mL/min/1.73 m2 over a median follow-up time of 5.7 years (interquartile range, 3.0–5.9 years). The eGFR <60 mL/min/1.73 m2 incidence rate per 100 person-years was 6.0 (95% CI 5.7–6.3) overall, 1.5 (1.3–1.9) in participants aged 45–54 years, 3.7 (3.4–4.0) for 55–64 year olds, 7.6 (7.1–8.1) for 65–74 year olds, 15.0 (13.0–16.0) for 75–84 year olds, and 26.0 (22.0–32.0) for those aged 85 years and over. In a fully adjusted multivariable model incidence was independently associated with age (hazard ratio 1.23 per 5-year increase; 95% CI 1.19–1.26), geography (outer regional and remote versus major city: 1.36; 1.17–1.58), obesity (obese class III versus normal: 1.44; 1.16–1.80), and the presence of hypertension (1.52; 1.33–1.73), coronary heart disease (1.13; 1.02–1.24), cancer (1.30; 1.14–1.50), and depression/anxiety (1.14; 1.01–1.27).

CONCLUSIONS

In participants with diabetes, the incidence of an eGFR <60 mL/min/1.73 m2 was high. Older age, remoteness of residence, and the presence of various comorbid conditions were associated with higher incidence.

A Systematic Literature Review of Application Development to Realize Paperless Application in Indonesia: Sectors, Platforms, Impacts, and Challenges
Authors: Prastyo Pulung Hendro , Sumi Amin Siddiq , Kusumawardani Sri Suning
Published: March 2020

Going paperless is an ideal form of the information era with the advantages of being time-efficient, environmentally friendly, proper documentation management, and it is an important step to improve the perception of the organization in the environmental field. From the environmental perspective, paperless is a concrete step to reduce the use of trees for paper. The paperless concept has been proposed by the government and has been legally guaranteed, so various sectors have begun to implement the paperless concept such as in the government, education, and industry sectors. However, there has been limited research that studies how many sectors implement paperless applications, the platforms that are used to develop paperless applications, the impacts of using paperless applications and the challenges for Indonesia. Therefore, this study aims to find out more details in the use of paperless applications in terms of sectors, platforms, impacts, and challenges for Indonesia. The data used in this study are articles of journal accredited by Sinta discussing the development of paperless applications in the government, education, and industry sectors from 2010 to 2019. The data are analyzed using the Systematic Literature Review method (SLR). The results of this study indicate that the sector that constantly develops paperless applications is the education sector, while the dominant platform used to develop paperless applications is the website. The impact of using paperless applications has a positive impact both in terms of performance, budget savings, and solving environmental problems generated by paper waste. Paperless applications are the solution in the digital era in supporting environmental preservation. The challenge is how the government makes regulations to support paperless applications in all agencies and provides financial support to sectors in which the use of paper is classified as significant but lacks funds in implementing paperless applications. Paperless applications must also be easy to use, and users must be provided continuous training so that paperless applications can be implemented easier.

Published: March 2020

Perovskites based on bismuth sodium titanates, Bi0.5Na0.5TiO3 (BNT), are incorporated into lead-free piezoelectric materials. Although BNT was discovered five decades ago, many aspects such as the structural complexity and the modifications produced when it is combined with other perovskites are not clearly understood. We studied the structural and microstructural properties of BNT upon addition of BaTiO3 (BT) and SrTiO3 (ST) during sol-gel synthesis. We characterized the ceramic powders by infrared and Raman spectroscopy, X-ray diffraction and scanning electronic microscopy. The addition of BT/ST modified the bonds, generating coexistence and phase transition and confirmed the existence of a morphotropic phase boundary.

Published: March 2020

Subject. The article addresses relations between the Russian Federation and foreign States, represented by the authorities of public law entities of each nation in the process of implementing the State policy on cross-border cooperation.
Objectives. We focus on assessing the implementation of the Russia's State policy in the field of cross-border cooperation through consideration of principles, objectives and areas of such cooperation.
Methods. The study draws on methods of systematization, classification, and comparison.
Results. We review the regulatory environment of cross-border cooperation, present principal powers of public law entities in the sphere of cross-border cooperation, describe the main types of cross-border cooperation between Russian regions and the territories of neighboring States. We pay special attention to the cross-border cooperation between the Russian Federation and the Republic of Kazakhstan (by highlighting the main forms of cross-border cooperation, the chronology and subjects of forums for interregional and border cooperation).
Conclusions. Today, a considerable number of States have concluded that the model of mutually advantageous cooperation is more beneficial for existence and development as compared to the model of isolated development. The scope, areas and forms of cross-border cooperation with border areas affect the development of respective regions and States as a whole, and contribute to better management of core capacities and near-border position.
An analysis of youth unemployment and entrepreneurship in the world today
Authors: Smirnov V.V. , Zakharova A.N. , Dulina G.S.
Published: March 2020

Subject. We consider the unemployment and entrepreneurship among young people.
Objectives. The aim of the study is to identify causes of youth unemployment and entrepreneurship in the modern world pattern.
Methods. The study rests on a holistic approach, using the methods of statistical analysis and cluster analysis.
Results. We specify the essence of youth unemployment, reveal the growth of unemployment in low- and middle-income countries, which is a driver of youth entrepreneurship. The problem of unemployment in low- and middle-income countries is addressed by shifting priorities from reducing the unemployment to increasing the employment. The high level of unemployment among young people prevails in developed countries with a high share in GDP and industrial output. First of all, this is due to the need to obtain a high level of education and qualifications for high-tech sectors of economy. Limited educational opportunities in low- and middle-income countries are not an obstacle to self-employment and entrepreneurship. The findings clarify the ontology of youth unemployment and entrepreneurship in the modern world, creating new competencies in relation to the public policy aimed at unemployment reduction.
Conclusions. The specifics of youth unemployment and entrepreneurship in the modern world is associated with consistently high indicators of poverty level of the working youth, which depends on gender characteristics. High unemployment is observed among young people, both men and women, however, the employment among male youth is significantly higher.

Authors: Timoshenko K.A.
Published: March 2020

Subject. This article analyzes the modern models for assessing the effectiveness of State external financial control bodies, highlighting their advantages and disadvantages.
Objectives. The article aims to conduct a comprehensive study on assessment of the effectiveness of the bodies of control and accounts of the Russian Federation and create a new model that helps draw complete and reliable conclusions about the effectiveness of the control activities.
Methods. For the study, I used the methods of logical, comparative, statistical analyses, and a strategic planning technique, or SWOT analysis.
Results. The article offers an original efficiency assessment model that provides a comprehensive analysis of each of the areas of activity of the control and accounts bodies in both preventive and ex-post control.
Conclusions. Modern approaches do not allow for an analysis of the effectiveness of preventive control. They need to get updated. It is necessary to introduce a unified methodology for assessing the effectiveness of control and accounts bodies, which will help not only identify and minimize shortcomings in the activities of previous periods, but also shape plans of control bodies' events for next years.
Analyzing the impact of financial momentum on the development of the economy
Authors: Smirnov V.V.
Published: March 2020

Subject. The article discusses the momentum in finance.
Objectives. The study reveals the impact of financial momentum as the unity of antipodes in the development of the national economy.
Methods. The study is based on a systems approach and methods of descriptive statistics.
Results. I discover the ultimate goal of globalization, i.e. the substantive simplification of national economies and strengthening of global economic ties. The goals determine the logic tendency of national economies for reducing the interest rate so as to gain the financial momentum and, consequently, fanning the crisis risk in the global financial system. The global financial system became the substance of global economic processes, which determined development opportunities of national economies. I reveal what countries have the high and low financial momentum.
Conclusions and Relevance. Being the unity of antipodes in the modern economic development, financial momentum causes countries to lose their economic identity, making them just functions of the global financial system. The cyclical development model of national economies is replaced with the metron model that rests on fluctuating advanced economies with the low financial momentum at its bottom and emerging economies at its top. The findings crystallize the concept and new competencies for a person who decide on the determination and performance of financial regulation activities.
Negative rates of central banks as a factor in the transformation of the global financial system in crisis anticipation
Authors: Evsin M.Yu. , Rybina I.A.
Published: March 2020

Subject. We consider the practice of applying negative interest rates by central banks of Switzerland, Sweden, Denmark, Japan and the Eurozone countries as a whole, and assess the effects of such policies.
Objectives. The purpose is to review emerging trends in the global financial system regarding the formation of interest rates, and to study preconditions for the emergence prerequisites for emergence of a new financial crisis.
Methods. The methodology involves correlation of inflation level, negative interest rates and GDP growth. We apply normative and integrated approaches to the study of interest rate formation by central banks at the present stage, general scientific and special methods of scientific knowledge, i.e. retrospective, systems and functional-structural analysis, observation; instrumental methods of grouping, sampling, comparison and generalization, evolutionary and dynamic analysis.
Results. The main problem faced by central banks is the lack of effective tools. This gave rise to the transformation of views on formation and implementation of monetary policy and, as a consequence, the introduction of negative interest rates. We present a logical model for negative interest rates policy implementation. In the short term, such a policy can yield positive results (GDP growth), though by a insignificant amount.
Conclusions and Relevance. The use of negative interest rates in the activities of world’s central banks is a serious prerequisite for crisis that can cause a transformation of the entire global financial system.

Methods. The study draws on the comparative analysis of key indicators of bank's financial statements one year prior to the introduction of provisional administration, and evaluates the results of existing methods for analyzing the financial standing of banks.
Results. The findings show that those methods that use only official reporting to assess the reliability of banks are not sufficient for short-term forecasting of financial stability. Ratings of the majority of agencies that rest on official reporting have a high percentage of erroneous results, therefore, rating agencies are not able to predict the regulator's decisions regarding a credit institution.
Conclusions. Currently, there are no universal methods to determine reliability, which would provide a correct forecast of deteriorated financial position of the bank. It is important to use a systems approach, where financial reporting is not a key component.

Authors: Ho Thi Anh , Nguyen Huyen Ngoc , Pham Thang Duc
Published: March 2020

Nd0.6Sr0.4MnO3 sample is fabricated by a solid-state reaction method and its magnetic, magnetocaloric properties are investigated. The Curie temperature, TC, at which a ferromagnetic-paramagnetic transition occurs is about 270 K. Based on an analysis using the Banejee’s criterion for the experiment results of magnetic-field dependences of magnetization and the universal curves of the normalized entropy change versus reduced temperature, we assess magnetic order existing in this sample. Furthermore, the maximum magnetic entropy change, which occurs near TC, measured at a magnetic field span of 50 kOe is about 6.0 J/kg.K corresponds to relative cooling power of 250 J/kg. These values are comparable to those of other manganites.
Gas sensors Based on U-shaped Graphene Nanoribbons: A First-Principles Study
Authors: Cuong Nguyen Tien
Published: March 2020

In this paper, I present first-principle calculations which are performed by using combination of DFT and NEGF methods to investigate the adsorption of CO2 and NH3 molecules on straight and U-shaped GNRs junctions. The density of state, molecular orbital, adsorption energy, transmission spectrum, and current-voltage characteristics were analyzed. It is found show that the adsorption of CO2 and NH3 on straight GNRs at the dangling bond edges exhibit chemical interaction behavior with high adsorption energy. Besides, for U-shaped ZGRNs without adsorption, the states around Fermi level are quasi-bound states localized at the zigzag edges. The electrons at these localized states are almost confined and do not contribute on conductance. However, for U-shaped GRNs with CO2 and NH3 adsorbed on dangling bond armchair edges, these states become delocalized on whole of the U-shaped junction. The current-voltage characteristics show that the sensitivity and selectivity of the U-shaped GNRs gas sensors are significantly improved in comparison with the pristine GNRs ones.

One of them is having their own calendar system which is totally different with the Balinese people have in common. Beside calendar systems, another unique tradition they had was Matruna Nyoman. This tradition is initiation ceremony for adolescents who grow up to manhood. In the Matruna Nyoman process, the adolescents of Tenganan get their education of tradition with the hope to be able to control their self physically and mentally, so they can represent the characters of Hindu’s youth. In this writing, it was done the analysis based on the theory of religion stated by E. B. Tylor. According to him, the religiosity came from human being’s consciousness toward spiritual concepts. In the functional structural theory of Durhkeim, he stated that interpreting the whole societies in the function matter of the constituent elements, especially norms, customs, traditions, and institutions. The result of this research shows that each adolescent of Tenganan Pengringsingan is able to gather to a head their knowledge and skill, so they can do their social duties based on Awig-awig of Tenganan Peringsingan custom village.

The majority of petroleum production comes from the brown field where production has decreased from year to year in Indonesia. To increase the recovery factor of petroleum from the reservoir, an advanced step of production is required, Enhanced Oil Recovery (EOR), which can optimize the depletion of old oil fields. EOR is the application of technology that requires cost, technology and high risk. Therefore, before implementing EOR, in a field, we must carefully evaluate both technically and economically to obtain an optimal additional recovery. This research was conducted to increase oil production by injection of Methyl Ester Sulfonate (MES). This study begins with a screening parameter crude oil, formation water, Berea’s core, and determination of phase behavior, interfacial tension (IFT), thermal stability, imbibition, and core flooding tests. The result for concentratin optimum in 0.3% MES and had IFT 0.3267 dyne/cm. The results of core flooding tests are: Recovery factor of waterflooding is 33.95 % and recovery factor of MES injection is 4.19 %.
