Suggestive causal impact of evening social media use on delayed sleep: Evidence from 230 million Reddit timestamps
Authors: Meyerson William , Fineberg Sarah Kathryn , Andrade Fernanda C. , Corlett Philip R. , Gerstein Mark B , Hoyle Rick H.
Published: April 2022

Public health officials and clinicians routinely advise social media users to avoid nighttime social media use due to the perception that this delays the onset of sleep and predisposes to the health risks of insufficient sleep. With some exceptions, the evidence behind this advice mostly derives from surveys identifying an association between self-reported social media usage and self-reported sleep patterns. In principle, these associations could alternatively be explained by users turning to social media to pass the time when they are otherwise having difficulty sleeping, or by individual differences that draw some people to frequent social media use, or by offline activities that overlap with both social media use and delayed sleep. To attempt to distinguish among these explanations, we leveraged estimated bedtimes from 50,000 Reddit users reported in a recent study and their 230 million posts to test whether the relationship between sleep and social media has properties suggestive of a causal relationship. We find that users are especially likely to be active on Reddit after their bedtime (and therefore awake) on nights that they posted to Reddit shortly before bedtime, especially if they posted multiple times or in high-engagement forums that night. Overall, this study lends additional support to the notion that there likely is some causal effect of evening social media use on delayed sleep onset.
Financial health and efficiency of Adam Sugar Mills Limited, Punjab, Pakistan
Authors: Sakib S M Nazmuz
Published: April 2022

The present report was produced to explore the financial health and efficiency of Adam Sugar Mills Limited, Punjab, Pakistan through analyzing financial ratios. This is an analytical study and the secondary data was obtained from Pakistan Stock Exchange, covering annual financial reports of the company for the years 2020, 2019 and 2018. The results of the report indicate that the company’s financial health remained dormant in the financial years 2018 and 2019. However, things rapidly changed in 2020. There are several reasons for it. One is that the government has accepted the demand of the sugar mills association to let them export sugar. This paved way for the shortage of sugar in the country and as a result the local demand was also rapidly increased. The prices are also increased due to supply and demand imbalance. The market conditions were favourable for the company in the year 2020. However, some management issues are highlighted as the explanation of lower financial performance in the previous two years. In 2019 company clearly face financial problems with respect to all financial ratios studied previously in the report. More expenses were made in these two years as compared to fewer expenses in 2020. The report recommends further improvement in the financial ratios by enhancing transparency and fair meaning in terms of finances.

The classification of inverse problems of dynamics in the class of ordinary differential equations is given in the Galiullin’s monograph. The problem studied in this paper belongs to the main inverse problem of dynamics, but already in the class of second-order stochastic differential equations of the Ito type. Stochastic equations of the Lagrangian structure are constructed according to the given properties of motion under the assumption that the random perturbing forces belong to the class of processes with independent increments. The problem is solved as follows: First, a second-order Ito differential equation is constructed so that the properties of motion are the integral manifold of the constructed stochastic equation. At this stage, the quasi-inversion method, Erugin’s method and Ito’s rule of stochastic differentiation of a complex function are used. Then, by applying the constructed Ito equation, an equivalent stochastic equation of the Lagrangian structure is constructed. The necessary and sufficient conditions for the solvability of the problem of constructing the stochastic equation of the Lagrangian structure are illustrated by the example of the problem of constructing the Lagrange function from a motion property of an artificial Earth satellite under the action of gravitational forces and aerodynamic forces.

The paper aims to study the model-theoretic properties of differentially closed fields of zero and positive characteristics in framework of study of Jonsson theories. The main attention is paid to the amalgam and joint embedding properties of DCF theory as specific features of Jonsson theories, namely, the implication of JEP from AP. The necessity is identified and justified by importance of information about the mentioned properties for certain theories to obtain their detailed model-theoretic description. At the same time, the current apparatus for studying incomplete theories (Jonsson theories are generally incomplete) is not sufficiently developed. The following results have been obtained: The subclasses of Jonsson theories are determined from the point of view of joint embedding and amalgam properties. Within the exploration of one of these classes, namely the AP-theories, that the theories of differential and differentially closed fields of characteristic 0, differentially perfect and differentially closed fields of fixed positive characteristic are shown to be Jonsson and perfect. Along with this, the theory of differential fields of positive characteristic is considered as an example of an AP-theory that is not Jonsson, but has the model companion, which is perfect Jonsson theory, and the sufficient condition for the theory of differential fields is formulated in the context of being Jonsson.

This article is devoted to the solvability of degenerate nonlinear equations of pseudoparabolic type. Such problems appear naturally in physical and biological models. The article aims to study the solvability in the classes of regular solutions of (all derivatives generalized in the sense of S.L. Sobolev included in the equation) initial-boundary value problems for differential equations. For the problems under consideration, we have found conditions on parameters ensuring the existence of solutions and we have proved existence and uniqueness theorems. The main method for proving the solvability of boundary value problems is the regularization method.

Published: April 2022

The coronavirus disease 2019 (COVID-19) has been responsible for over three million reported cases worldwide. The construction of an appropriate mathematical (epidemiological) model for this disease is a challenging task. In this paper, we first consider susceptible — infectious — recovered (SIR) model with constant parameters and obtain an approximate solution for the SIR model with varying coefficient as it is one of the simplest models and many models are derived from this framework. The numerical experiments confirm that the proposed formulation demonstrates similar characteristic behaviour with the well-known approximations.

In this paper, we study formal characters of simple modules with singular highest weights over classical Lie algebras of type B over an algebraically closed field of characteristic p ≥ h, where h is the Coxeter number. Assume that the highest weights of these simple modules are restricted. We have given a description of their formal characters. In particular, we have obtained some new examples of simple Weyl modules. In the restricted region, the representation theory of algebraic groups and its Lie algebras are equivalent. Therefore, we can use the tools of the representation theory of semisimple and simply-connected algebraic groups in positive characteristic. To describe the formal characters of simple modules, we construct Jantzen filtrations of Weyl modules of the corresponding highest weights.

In this paper, we study the interpolation properties of the net spaces N_p,q(M), in the case when M is a sufficiently general arbitrary system of measurable subsets from R^n. The integral Urysohn operator is considered. This operator generalizes all linear, integral operators, and non-linear integral operators. The Urysohn operator is not a quasilinear or subadditive operator. Therefore, the classical interpolation theorems for these operators do not hold. A certain analogue of the Marcinkiewicz-type interpolation theorem for this class of operators is obtained. This theorem allows to obtain, in a sense, a strong estimate for Urysohn operators in net spaces from weak estimates for these operators in net spaces with local nets. For example, in order for the Urysohn integral operator in a net space, where the net is the set of all balls in R^n, it is sufficient for it to be of weak type for net spaces, where the net is concentric balls.

We consider a boundary value problem for the fractional diffusion equation in an angle domain with a curvilinear boundary. Existence and uniqueness theorems for solutions are proved. It is shown that Holder continuity of the curvilinear boundary ensures the existence of solutions. The uniqueness is proved in the class of functions that vanish at infinity with a power weight. The solution to the problem is constructed explicitly in terms of the solution of the Volterra integral equation.

The theory of fractional calculus developed rapidly as the applications of this branch are extensive nowadays. There is no discipline of modern engineering and science that remains untouched by the techniques of fractional calculus. In fact, one could argue that real world processes are fractional order systems in general. In this article, we obtain the semi-integrals of certain algebraic functions in terms of difference of two complete elliptic integrals of different kinds by using series manipulation technique.

New technologies, including Industry 4.0, are rapidly changing traditional and high-tech industries, and forming the advanced manufacturing sector within the industrial complex. By now Russia has been characterized by a modest presence in the world advanced manufacturing markets – Russia’ share is less than 0.6% in certain markets and less than 0.4% in global advanced manufacturing. This is partially explained by the scarce commodity range in the Russian export basket, which determines weak representation of Industry 4.0 goods. Large part in the Russian advanced manufacturing exports is traditional for the Russian economy goods — airplanes, turbojet engines, fuel rods. However, we observe positive structural changes in Russian exports caused by the COVID-19 pandemic. Russia has increased exports of goods with bio- and additive technologies, optoelectronics. It seems that the entry to new advanced manufacturing markets for Russia can form the basis for long-term growth. International experience shows that advanced manufacturing exports are often supported by advanced manufacturing imports. We find that Russian economy significantly underutilizes this channel. Although Russian advanced manufacturing imports are gradually growing, it is focused primarily on final consumer goods. We consider industrial robots as a case of advanced manufacturing imports that deserves special attention as a widespread cross-cutting technology that can significantly transform the technological level of industries. Our estimates show that, although the robotics market in Russia is relatively small and has low growth rates relatively to investment in fixed assets, companies importing industrial robots are larger and more productive. This evidence allows us to determine the import of industrial robotics as one of the priority directions of modernization of the Russian manufacturing. Based on the analysis we identify and discuss three growth opportunities for Russia in global advanced manufacturing: 1) support of exports of services in optoelectronics and ICT through the use of accumulated human capital and competencies and taking into account fast transformation of business models in industry, 2) support of exports of biotechnology products, taking into account positive reputational effects and expanding Russian pharmaceutical exports under the COVID-19 pandemic; 3) support of technology companies in wide number of advanced manufacturing taking into account current favorable environment for the birth of tech startups in Russia.
Technological entrepreneurship as a development factor of Russia
Authors:   Russian Presidential Academy of National Economy and Public Administration (RANEPA), Moscow, Russia, Zemtsov S.P.
Published: April 2022

Technological entrepreneurship is a potential driver of Russia’s socio-economic development. But an optimal combination of environment and business networks (entrepreneurial ecosystem) to be formed is very rare and depends on many factors. The article discusses the potential role of technology start-ups in diversification, economic and employment growth, and adaptation to technological changes. The number of start-ups in Russia had decreased since 2015, and there is a low entrepreneurial activity in comparison with other countries. In general, the change in the industry structure of startups in Russia is consistent with the global trends; the role of knowledge-intensive business services and ICT is high and growing, the share of manufacturing is declining. We revealed the determining role of socio-cultural factors, human capital and universities, business climate and access to foreign markets in the creation and success of technology companies, as well as the contradictory impact of state support. Significant and increasing role of immigrants and diaspora abroad is underestimated for Russia. We noted the inability of the widespread development of successful technology companies (“gazelles”, “unicorns”); identified regional and sectoral priorities for public policy. We examined the main elements and models of national entrepreneurial ecosystems, limitations and prospects for their application in Russia.

Among the outstanding technology startups of the international level, there are often companies created by the Russian founders: Telegram, Revolut, Miro and many others. The authors wondered how the technology startups founded by Russians were distributed around the world and how many stayed in the country. This led to a few related issues. In which jurisdictions are tech startups with the Russian origin more comfortable to exist and why, where it is more probable to attract higher investment, in which industries Russian founders create startups? The issue of determining the “Russian origin” of the founder deserves special attention. The authors define it through higher education: if the founder received a Russian higher education, then, regardless of citizenship and nationality, he is considered as a Russian. The study analyzes the educational trajectories of the founders, the connections of headquarters’ locations with origins of the founders, the profiles of the founders (age, work experience and other characteristics). The role of universities in the education process of technological entrepreneurs is revealed, including the potential for generating technological entrepreneurs in various regions of the country. The authors conclude that while the absolute amount of investment attracted in Russia is maintained at the same level, its share is falling. The number of technology startups choosing Russia as their main jurisdiction is also decreasing. Results show that success in attracting investment is positively affected by the early experience in launching a startup (university years), as well as by technical education. The authors state the difference in the industry structure of startups created by the Russians from the world average in favor of IT, robotics, and artificial intelligence to the detriment of medicine, trade, and business services. The conclusion is: universities in such cities as St. Petersburg, Yekaterinburg, Novosibirsk are poorly using the potential of generating technological entrepreneurs.

Modern animal breeding is a high-tech industry. It utilizes advances in genetics, biotechnology, and the Internet of Things. In Russia cattle breeding is characterized by high dependence on imported technologies and genetic material, the share of which is up to 90–100%. The domestic scientific and technological potential has had weak incentives to develop in recent years. The aim of the article is to identify, on the basis of patent analysis, scientific and technological areas in cattle breeding with sufficient scientific potential, and areas where domestic potential is insignificant, but it is critically important to develop it. The analysis for the period 2006–2020 in four technological areas — biotechnology, veterinary medicine, feed production and smart farming technologies, — shows that the main patentable developments of Russian applicants are concentrated in veterinary medicine and feed production. This is mostly the legacy of Soviet scientific schools. Modern technologies, especially biotechnology, are undeveloped. Possible solution is to develop technological capacity by licensing foreign technologies and the localization of production.

In our paper, for the first time, we examine the influence of the sentiment of private investors in social networks on the trade characteristics of stocks in the Russian market. Monthly return rates and trading volumes are analyzed under the control of financial indicators and indicators of the quality of corporate governance of stock issuers, as well as the changing external environment in the period from 2013 to 2020. The sample for various sentiment metrics is based on unique data: messages in the Telegram and mfd.ru platforms. The tonality of messages is diagnosed according to the authors’ method using artificial intelligence (neural network). The main conclusion is: the sentiment can be seen as an explanatory factor in pricing and trading activity. The influence of sentiment is non-linear. The author’s HYPE indicator of sentiment is proposed and compared in terms of explanatory ability of the trade characteristics with a wide range of proxy variables. The explanatory ability to identify differences is realized through regression constructions on panel data. It is shown that trade characteristics are more sensitive to the growth of negative messages, which is consistent with the postulates of behavioral finance. An increase in messages’ number of both positive and negative sentiment contributes to the growth of trading activity. An important practical conclusion is: following the crowd when the company is most intensely discussed will not result in high returns to an investor.
Is there a natural rate of crime in Russia?
Authors:   St. Petersburg University of the Ministry of Internal Affairs of the Russian Federation, St. Petersburg, Russia, Myachin N.V.
Published: April 2022

According to the concept of the natural rate of crime the number of crimes committed in the long term depends not on the direct costs of society to combat them, but on the quality of the work of socio-economic institutions. Empirical verification of the presence of this phenomenon in some countries is reflected in foreign studies, while in Russia such works are more descriptive than applied. At the same time, determining the natural rate of crime is important for the strategic planning in the economy, as it allows minimizing the costs of combating crime and increasing the efficiency of budget expenditures. The purpose of this article is to check whether there is a natural crime rate in Russia. For this purpose the indicators of the crime rate in Russia from 1992 to 2020 are analyzed using unit root tests. We apply both conventional unit root tests and tests that take into account structural breaks and spatial correlation between the subjects of panel data, which are the federal districts. The results of the study allow to conclude that there is a natural crime rate in Russia for rapes, hijackings and traffic violations. In the context of the deterrence hypothesis, counteracting these types of crimes will lead to a temporary decrease in their level, which will inevitably return to its previous values. The author attributes the absence of a natural level for most types of Russian crime to the state of public institutions and the mobility of the institutional structure, as well as to the limitations of official criminal statistics.
Stablecoins: Classification, functional features and development prospects

Published: April 2022

The article is devoted to stablecoins and their prospects for use in the financial market. The authors propose the interpretation and classification of stablecoins and analyze their functional features and development prospects. Also impact of the global economic crisis on stablecoins is analyzed. The findings illustrated that stablecoins differ from traditional electronic money, as well as classic cryptocurrencies, and they can be interpreted as hybrid digital financial assets. Currently, the commonest digital coins with a stable rate are local stablecoins with backing. At the same time, both in terms of capitalization and transaction volume, dominated by centralized fiat-backed and gold-backed stablecoins. Decentralized non-backed stablecoins are not widespread, despite a number of technological innovations that may underlie their stabilization mechanism. The authors have identified main scenarios for the use of local and global stablecoins in the near future. It was observed that at a time of decreased volatility stablecoins are currently predominantly used as a tool to minimize the risk of price volatility in the crypto-assets market. In contrast, the growing interest in applying of global stablecoins under the new reduction volatility mechanisms, may encourage the extensive use of stablecoins in both retail and wholesale payments at the international level. In addition, the development of global stablecoins may entail risks to financial stability and the functioning of monetary systems, to minimize which it is necessary to develop a regulatory framework and financial procedures that take into account the possibility of a wide circulation of stablecoins.

Published: April 2022

Regional innovative clusters unite various organizations related to high-tech industries, which is located in concrete region, on the basis of cooperative activity, common interests and complementarity to their functions, resources and capabilities. This accelerates research and development processes and provides market entry of final product that is of fundamental importance for competitiveness of manufactured product as well as of regional innovative cluster as a hole and region of its location. The paper aims to develop methods and recommendations on technology transfer in regional innovation cluster as a tool for optimization of risks of its innovation activity. They include the development of the methodology for decision making on transfer of technology in innovation cluster under uncertainty and risk. As a result, we made calculations on the conditional example, in accordance with proposed methodology. In conclusion, application of proposed methodology in regional innovation cluster allows to optimize risks at the stage of implementation of developed technology in the manufacturing of final product and to accelerate its market entry that can be considered as a factor of regional economic competitiveness.
On the impact of acquiring citizenship on some socio-economic characteristics of migrants and their position in the labor market

The article discusses the possible impact of migrants’ citizenship of the host country on their socio-economic characteristics. The topic of the economics of citizenship (in various aspects) is extremely relevant and found wide coverage in foreign literature. In domestic practice, it remains poorly developed due to the lack of data suitable for such studies. Comparative analysis of the characteristics of migrants, usually migrant-workers, and the local population can be often found in the publications of the Russian scientists, but rarely investigated is the question of how the economic characteristics of migrants who have already become Russian citizens differ from those of foreigners. In 2019, for the first time in the modular survey conducted by Rosstat on the basis of the Labor Force Survey (LFS), information was collected on the migration status of respondents: their country of birth and duration of residence in Russia. Combination of these variables with citizenship made it possible to distinguish three groups of respondents: migrants who already have Russian citizenship, foreigners, and non-migrants. The work with microdata at the level of descriptive statistics showed, as expected, that foreigners differ significantly from other groups of respondents. On average, they are younger, less educated, have a higher labor force participation rate, and are more likely to work in labor-intensive sectors of the economy that do not require high qualifications. The minimal differences between non-migrants and migrants with Russian citizenship may be related to a large proportion of migrants who moved to Russia long ago. The significant shortcomings of the survey questionnaire, combined with a very low representation of foreigners in the sample (which does not correspond to their share in the Russian population), limited the analytical potential of the information. Identification of methodological problems of the LFS concerning the collection of information on migration and the development of recommendations addressed to Rosstat became a special task of the study. The main conclusion of the article was that the potential of the LFS is not used for a comprehensive study of international migration, and the inclusion of the migration module in an unchanged form in the program of the regular LFS for 2021 and further can make the problem chronic.
Value of statistical life in Russia based on microdata
Authors:   Lomonosov Moscow State University, Moscow, Russia, Zubova E.A.
Published: April 2022

Value of statistical life (VSL) is a widely used instrument for risk monetizing towards public policy planning in many developed countries. In Russia, due to the lack of data required for calculations, there are practically no credible estimates comparable in terms of methodology used, while those that are obtained using a different methodology hereupon differ significantly in magnitude. In our research, the value of statistical life in Russia is estimated using the comparable to foreign studies’ methodology, based on the RLMS-HSE survey microdata, the Russian (Rosstat) data, and the U.S. (BLS CFOI) data on occupational risks for 2018. The basic idea of this approach is to determine the willingness of employees to accept compensation for occupational risk. The resulting estimates of the VSL are in the range from 366,2 to 497,6 million rubles (2018). These values are significantly higher than all available estimates for Russia obtained using a different methodology but comparable to the corresponding values calculated with a similar methodology for the United States, considering the difference in GDP per capita at PPP.
The nature of humanism and materialism of Marx’s concept of man

Published: April 2022

This paper is devoted to clarification of Marx’s view of man in terms of his special humanism and materialism. The authors argue that Marx’s works contain normative elements and the basic value for him is free human self-realization. But this self-realization doesn’t serve as a mean for embodiment of certain human ideals; it is the end in itself. So, the authors qualify Marx’s position in comparison with other kinds of humanism as non-directed anthropocentrism. Marx rejects the autonomy of abstract ethics, as well as any abstract categories, and raises the significance of human practice as the process of life’s actualization. In this context, the historical materialism of Marx appears closely related to his conception of man as an active agent of history and creator of material world: significant part of material world is interpreted by Marx as the estranged and objectified human subjectivity; nature and man are perceived as the dialectical unity, and the first one acquires its significance only as the living space of the second. This allowed the authors to propose the term “subjective materialism” for defining Marx’s approach. Even in Marx’s later works, the historical task of developing productive forces appears to be permeated with the general humanistic goal of full human liberation and recovery its primacy in relation to the external world. And this task appears to be the key trend of the history in the Marx’s conception.

В обробку первинної соціологічної інформації було включено дані 114 анкет, із них: 37 анкет ВАТ Криворізький завод «Універсал», 37 анкет ОАО «Миттал Стил Кривой Рог» та 40 анкет ТОВ Криворізької швейної фабрики «Старт». Визначено високий ступінь твердження і прийняття основних цінностей і норм, які вважаються на цей момент часу культурними досягненнями в сфері фізичної культури і спорту, а також відносно низьку активність їх використання в діяльності не залежно від статті, віку і соціальної статусно-рольової функції. У жінок відмічено більш чуттєве розуміння теоретичної значимості фізичної культури як суспільної категорії та в два рази нижче, ніж у чоловіків, як категорії особистої культури. Установлена тенденція зниження інтересу до фізичної культури і спорту у віковій категорії з 30 до 44 років, а потім з 45 до 59 років - його зростання. Освітній рівень, який є вищим у працівників інженерно-технічного контингенту, ніж у робітників, впливає на формування цінностей, що проявляється, насамперед, у більш високій активності використання засобів фізичної культури і спорту.

A proposed method for selecting and scaling recorded seismic accelerations according to TCVN-9386:2012
Authors: Nguyen Xuan Dai , Nguyen Van Tu
Published: April 2022

Accelerogram is a significant input in seismic analysis of structures, particularly for performance-based seismic designs and for advanced technologies using nonlinear energy dissipation devices. However, in seismic regions like Vietnam, earthquake data is generally scarce. Vietnam Standard TCVN-9386:2012 mentions the use of recorded accelerogram for seismic analysis, although it contains shortcomings. The paper aims to detail the procedure of selecting and scaling recorded seismic accelerations according to requirements specified by TCVN-9386:2012. The target response spectrum and the fundamental vibration period of the considered structure are critical factors for the selecting and scaling process. The proposed procedure essentially includes converting the two original horizontal accelerations to the principal directions, correcting the relative proportion between the two acceleration components, determining the period range of interest, calculating the scaling factors, and verifying the 10% matching criteria. An example is conducted on a typical set of accelerations to detail the application of the proposed procedure. The results show that the response spectra of calibrated accelerations are consistent with the target spectrum and satisfy the requirements of TCVN-9386:2012, suggesting that the proposed method can be applied to the seismic analysis of structures with high reliability.

Históricamente, los grupos humanos hanocupado espacios geográficos convirtiéndolos en territorios y, de acuerdo con sus necesidades y limitaciones, los han transformado, haciendo uso de los recursos que este les proporciona, modificando los escenarios naturales en contenedores de valores culturales tangibles e intangibles donde se expresa la relación simbiótica de ellos con la naturaleza. Desde el siglo XIX se ha venido analizando el paisaje desde sus características físicas, antrópicas y naturales, pero ha sido en el último siglo donde se ha estudiado desde su complejidad en la interacción de todos sus elementos
TOKAT’TA ALTERNATİF TARIM ÜRÜNÜ OLARAK LAVANTA YETİŞTİRİCİLİĞİNE UYGUN SAHALARIN ANALİTİK HİYERARŞİ SÜRECİ İLE BELİRLENMESİ

Primer faaliyetler arasında yer alan tarım, Dünya’nın en eski ve insan hayatı için en önemli üretim aracıdır. Bu üretimin şekillenmesinde uygun iklim koşulları, verimli tarım arazileri ve su kaynakları etkin rol oynar. Karadeniz Bölgesi’nden İç Anadolu Bölgesi’ne geçiş kuşağında yer alan Tokat, zengin bir hidrografya ağına ve verimli tarım arazilerine sahiptir. Mevcut potansiyeline rağmen tarım arazilerinde sulama imkânlarının yeterince geliştirilememesi, tarımsal üretimden alınan verimi düşürürken, kuru tarım alanlarında yapılan münavebeli ekim ve nadas uygulaması da her yıl yüzlerce dönüm arazinin tarım dışı bırakılmasına neden olur. Kuru tarım alanlarında üretimin devamlılığını sağlamak adına, yörenin ekolojik isteklerine uygun yeni ürünlerin yetiştirilmesi gerekir. Bu çalışmada toprak seçiciliğinin az olmasının yanında geniş kullanım alanlarına sahip ve ekonomik getirisi yüksek bir bitki olan lavantanın, alternatif bir tarımsal ürün olarak Tokat tarımına kazandırılması amaçlanmıştır. Bu amaç doğrultusunda lavanta bitkisinin ekolojik isteklerinin yörenin ekolojik koşullarına uygunluğu incelenmiştir. İncelemede kullanılan parametrelere ait veri tabanı ile katman haritaları oluşturulurken coğrafi bilgi sistemleri (CBS) teknikleri ve analitik hiyerarşi süreci (AHS) analiz metodundan faydalanılmıştır. Analiz sonucunda kuru tarım yapılan alanların %29’luk kısmının lavanta yetiştiriciliğine uygun olduğu tespit edilmiştir. Bu sahalarda halihazırda üretilen buğday ve arpa gibi ürünlerin yerine çok yıllık bir bitki olan lavantanın tercih edilmesi nadaslı tarımı büyük oranda ortadan kaldırırken, sürdürülebilir kırsal kalkınmaya da katkı sağlayacaktır.
