Published: January 2022

In recent years, forecasting has received increasing attention since it provides an important basis for the effective operation of power systems. In this paper, a hybrid method, composed of kernel principal component analysis (KPCA), tree seed algorithm based on Lévy flight (LTSA) and extreme learning machine (ELM), is proposed for short-term load forecasting. Specifically, the randomly generated weights and biases of ELM have a significant impact on the stability of prediction results. Therefore, in order to solve this problem, LTSA is utilized to obtain the optimal parameters before the prediction process is executed by ELM, which is called LTSA-ELM. Meanwhile, the input data is extracted by KPCA considering the sparseness of the electric load data and used as the input of LTSA-ELM model. The proposed method is tested on the data from European network on intelligent technologies (EUNITE) and experimental results demonstrate the superiority of the proposed approaches compared to the other methods involved in the paper.

The article is dedicated to the glowing memory of the talented Ukrainian scientist-mechanic, professor, doctor of physical and mathematical sciences Vyacheslav Vladimirovich Meleshko. The sound fields of several coherent vortex structures interacting with each other were calculated using the moment model (MZS-model) of the first and second orders. In the first-order MZS-model, vortices are described by point vortices, in the second-order MZS-model--by Kirchhoff vortices. Sound fields as a result of vortex interaction are calculated using the Lighthill's acoustic analogy under Powell's formulation. The spectrum of the sound field in the description of coherent vortices by point vortices is characterized by a single frequency band, which reflects the motion of the vortex centers of vortices (large-scale vortex movements). Taking into account the inner vortex dynamics leads to the expansion of spectrum and level increasing of calculated sound: the lower band describes the motion of the vorticity centers of spots, the higher band describes the internal dynamics of the vorticity. It is shown that large-scale vortex movements can be modeled by point vortices, when the sound spectrum of distributed vortices is clearly divided into bands and the width of the lower frequency band is close to the width of the sound spectrum from point vortices. The presence of an upper frequency band in the sound field of interacting vortex spots does not allow us to describe the distributed vortices as point vortices when constructing a sound source, since such a simplification leads to a significant underestimation of the level of the calculated sound field.

The principles of in-situ nuclear reaction techniques and the need for them in various fields of scientific research are considered; several examples of the application of these techniques are given. It is shown that the techniques of in-situ nuclear reactions are effective in studying the diffusion of deuterium in metals at temperatures below room temperature, the diffusion of deuterium in proton-conducting oxides, the quantum diffusion of deuterium in metals at cryogenic temperatures, and the chemical composition of oxide nanopowders when they are heated in vacuum. Promising applications of nuclear reaction techniques in situ are formulated.
The influence of 2 at. % Si addition on the annealing of radiation-induced defects in the Fe-13Cr alloy
Authors:   M.N. Miheev Institute of Metal Physics, Ural Branch of the Russian Academy of Sciences, Nikolaev A. L.
Published: January 2022

The paper presents data on electrical resistivity recovery in the Fe-13.4Cr and Fe13.6Cr-1.9Si alloys during isochronal annealing after 5 MeV electron irradiation below 77 K. Long-range migration of radiation-induced defects starts slightly above 200 K in Fe-13.4Cr. The silicon addition in Fe13.6Cr-1.9Si leads to immobilization of Frenkel pair defects thus making the peaks of the stages of the onset of long-range migration shift towards high temperatures up to 370 K and 420 K for self-interstitial atoms and vacancies, respectively. This finding confirms the data obtained earlier for Fe16Cr-Si alloys by means of positron annihilation technique (JNM 508(2018) 100–106) on trapping of radiation-induced defects on Si agglomerates (clusters consisting of several silicon atoms) formed during defect migration.

Magnetostriction of the tempered 60G steel in the magnetic field of a solenoid is studied. A technique is proposed for dividing magnetostriction into components, namely those induced by the displacement of interdomain boundaries and those caused by the mechanism of rotation of spin magnetic moments. The dependences of the magnetostriction components on the tempering temperature of the hardened steel are constructed. This contributes to an increase in the effectiveness (accuracy) of evaluating elastic stresses in a steel structure by magnetoelastic methods. The essence of the technique lies in the application of the Langevin function to describing the experimental magnetostriction curves of the tempered 60G steel.
Financial Inclusion Tool for People with Disabilities
Authors:   , Loseva Oxana , Dion Genevieve
Published: January 2022

One if four people have a disability, that's 61 million Americans. They have $490 billion in investible income. However, we currently do not design with people with disabilities in mind. There are many barriers to financial services for people with disabilities - investing is not taught in schools and is often not encouraged for people with disabilities to partake in. Special education curricula rarely covers financial wellness and it falls on the parents to educate their children with disabilities about finances. Parents are also primary financial decision makers and often have full access to their children's bank accounts. This results in lack of financial privacy and lack of financial independence for people with disabilities. Other barriers are social security benefits, people receiving social security benefits cannot have more than $2000 in income, any amount that exceeds that limit will result in loss of social security benefits. In my thesis, I am addressing the gap of lack of financial education for people with cognitive disabilities. I have developed a tool, a game, that teaches people with disabilities how to invest and manage money. It is an interactive way to learn about money management and can be played alone or with family and friends. Players experience market fluctuation and real-life money examples that they have to navigate in order to maintain their checking and savings accounts. These are the skills that they can develop and then apply to their real bank accounts. Key words: accessibility, inclusion, cognitive disability, financial wellness, money management, investing, game design
Aggregation and Disaggregation of Information
Authors:   , Chen Yuyue , Benson Hande Yurttan
Published: January 2022

This dissertation develops optimization solutions to tackle two challenges in data mining: intelligence aggregation and signal disaggregation. For each challenge, our solution consists of an optimization model and an efficient and robust algorithm to solve it. We first present a model and a solution algorithm that can decompose aggregated information into smaller constituents for multiple systems. For instance, our approach simultaneously disaggregates integrated energy signals from houses into specific measurements of appliances/activities. The results provide managerial insights for energy services without costly installing additional hardware. Unlike some traditional approaches in the literature that require large training datasets, our disaggregation algorithm uses contextual features as inputs combined with a transfer learning approach to improve model accuracy and interpretation. Next, we propose a new optimization approach to aggregating information from multiple information sources. Our model is solved with an alternated quadratic programming optimization and has been evaluated to accurately predict a stock's future trading actions by capturing inter-correlations and quantifying the reliability scores of analysts' recommendations. We further extend our aggregation model with additional time-related relevance features. The extension allows us to improve the prediction accuracy of stock future performance as well as to better understand the impact of time-dimension on aggregation tasks. Although disaggregation is the inverse process of aggregation, we investigate both topics by incorporating various types of inter-correlations in complex systems. The optimization models in this dissertation can be further applied to other research fields such as healthcare, airline business, marketing, and operations management.

Published: January 2022

Ca dao about couple's love are a part of Vietnamese folklore. In this article, we study Ca dao about couple's love from the perspective of pragmatics, specifically showing communication strategies used by folk authors. Through the survey, we found that, in order to establish and maintain a harmonious relationship in communication, folk authors have had strategies to choose appropriate words and ways to establish appropriate linguistic actions. In addition, they implement the strategy of creating implication by using ambiguous, roundabout speech and using indirect-speech actions. Reasonable communication strategies have contributed to helping folk authors achieve optimal communication purposes.

Attractiveness in the physical beauty in order to clarify the humanity in love is one of great contribution of contemporary Vietnamese poets. According to existentialist ideology, human is born without deciding their own fate. They always feel anxious about the fragmentary loss of human life that makes them always feel lonely. But they also accept their loneliness and rise up to live and affirm their own individuality. And sexuality is one of the key themes of existentialism people to find the meaning of life and overcome the kama of loneliness. The contemporary Vietnamese poetry since 1986 has been greatly influenced the existentialism from the West and has been shared a new look at the theme of "sexuality". The article mentions the remarkable contributions of contemporary Vietnamese poets to the renewal of poetry, give readers a new conception and awareness of the theme of "sexuality" which is prohibited and avoided mention to both in real life and in literature.

Authors: Nguyen Hoang Thai Khang , Tran Thi Quynh Thi
Published: January 2022

The study applies Livelihood Vulnerability Index (LVI) and LVI-IPCC to assess the level of livelihood vulnerability of households in Binh Ngoc commune under the impacts of climate change. The LVI includes 7 main factors: household characteristics, livelihood strategies, social networks, health, water resources, food and finance, natural hazards, and climate change. Based on the average value of these key factors, the LVI-IPCC index is made up of three factors: exposure, adaptability, and vulnerability. Calculation results in Binh Ngoc commune show that the LVI and LVI-IPCC indexes have values of 0,278 and 0,016 respectively. This reflects that livelihood vulnerability is not too high, and vulnerability to climate change impacts is moderate. However, the local exposure to climate change impacts is relatively high with a value of 0,476. Besides, people's adaptability is also relatively good with a value of 0,345 and vulnerability is also moderate with a value of 0,126.

Authors: Cao Thi Viet Anh
Published: January 2022

As one of the civilized centers of the Eastern world, with comprehensive economic, political, and cultural power, China soon spread strong influences outside but directly with the neighboring nations, including Vietnam. One of the ways to spread China's power is based on the business of its own merchants. Due to the changes in historical context, especially the decline of feudal production relations, the risk of invasion of Western colonialism, especially the official invasion of French colonialism since 1858 in Vietnam, the commercial activities of Chinese merchants according to the same characteristics as many previous historical periods have appeared new features bearing the marks of the era. Therefore, researching the mediating role of Chinese merchants in Vietnam during the XVII-XIX centuries will help us to have a more comprehensive view of Vietnam’s history generally and the economic picture of Vietnam, particularly within a fierce historical period.

O CASO DA VARA (1891): UM CONTO DE MACHADO DE ASSIS QUE REVELA A FACE DA ESCRAVIDÃO BRASILEIRA DO SÉCULO XIX
Authors: Vilarinho Murilo Chaves
Published: January 2022

Machado de Assis, por meio de seus escritos literários, verdadeiras narrativas históricas (CHALHOUB, 2003), legou à posteridade elementos de memória capazes de auxiliar a compreensão do ter-sido, ou seja, daquilo que o passado encobriu (RICOEUR, 2007). O escritor observou o cotidiano social do Rio de Janeiro dezenovesco, que forneceu para seus escritos substância histórica que corroborou a estruturação de seus romances, crônicas e contos- genuínos registros da história social brasileira, mesmo que ficcionais. Este capítulo objetiva refletir sobre a escravidão negra, por intermédio do conto O Caso da Vara (1900). Foi empregado pesquisa bibliográfica e análise documental para abordagem do texto. Conclui-se que, de modo astucioso e crítico, o significado negativo da escravidão na vida daqueles que eram considerados meros objetos, não passou despercebido aos olhos do intelectual.
O LOUCO INTERDITADO: O DR. NINA RODRIGUES E OS EMBATES ENTRE O SABER MÉDICO E O PODER JUDICIÁRIO
Authors: Bezerra Rafael Santana
Published: January 2022

No Brasil, o estabelecimento das regras para internamento e interdição civil de “alienados” só foram possíveis a partir de 1916 com a promulgação do primeiro Código Civil brasileiro. Até então, regiam-se essas categorias a partir das Ordenações Filipinas ou de legislações específicas que funcionavam para determinadas instituições médicas, como a própria lei de 1903. Dada à desorganização sobre a matéria, emergiram inúmeros casos de “sequestrações ilegais” de pessoas sãs em asilos hospitalares, além de interdições jurídicas consideradas injustas ou mal intencionadas. Este trabalho tem como objetivo analisar a atuação de médicos legistas contra as imposições do poder jurídico aos sujeitos considerados alienados. Trata-se de identificar as lutas e estratégias de enfrentamento do campo médico contra o campo jurídico. Dois espaços de poder em luta pela legitimidade do saber científico e pelo domínio de um objeto: o louco interditado. Para isso, analisaremos especificamente, a atuação de Raimundo Nina Rodrigues, médico-legal, professor da Faculdade de Medicina da Bahia, nos tribunais de justiça.

Choice of gas temperature at the turbopump turbine inlet
Authors: Ivanov A. V.
Published: January 2022

The article considers some issues of choosing the gas temperature at the inlet of a liquid rocket engine turbopump turbine. The turbine is one of the key elements of the engine and its operability depends on the gas temperature. In addition, the turbine inlet gas temperature determines its power and main parameters of the engine chamber pressure and thrust. The higher turbine inlet gas temperature, the higher the chamber pressure and the better engine performance. The permissible temperature of the turbine structure is determined by the required safety margins and durability of the turbine rotor blades. For expendable engines, the safety margin is determined by the material short-term strength at maximum gas temperature. For reusable engines with a long service life, the safety factor is determined by the material long-term strength. The article presents the main factors affecting the choice of the generator gas temperature. It shows that one of the main factors is the non-uniformity of the temperature field at the turbine inlet. The choice of maximum admissible temperature is determined not so much by the engine schematic with the afterburning of oxidizing or reducing generator gas, but by the strength and durability of the structure with account of the influence of temperature factors.
Parametric study of the influence of location and extension height of the rod interceptor on jet engine nozzle characteristics
Authors: Tishchenko K. O. , Brykov N. A. , Belyaeva A. S.
Published: January 2022

Modern aircraft need increased maneuverability to maintain a competitive position. One way to improve this characteristic is to use methods to adjust the thrust vectors of a jet engine nozzle. One method of controlling nozzle thrust is the use of nozzle interceptors devices of various shapes that extend into the nozzle channel and cause an uneven distribution of pressure along the walls of the channel. The extension of the rod interceptor near the critical section of the nozzle creates a greater lateral force than the extension of the rod near the exit section. The dependence of the lateral force on the extension height is nonlinear. The article presents a description of a nozzle interceptor of a cylindrical shape extended from the channel wall. Numerical simulation of gas flow in the nozzle with a cylindrical interceptor was carried out. The patterns of gas flow in the channel and in the environment outside the nozzle are presented. The plots of the lateral and axial components of the thrust force against the interceptor rod length are also presented for both cases of the rod location. Rod interceptors can be used in combination with other correcting devices.

Published: January 2022

The article discusses one of the ways to improve the efficiency of low-temperature power plants. Selection of the working substance for the auxiliary low-temperature power circuit is a relevant option for increasing the power. The low temperature potential of cryogenic substances is used to improve the efficiency of energy systems. Auxiliary power plants operating according to the Rankine cycle and the Brayton cycle were used in the work since these cycles are most efficient for the operation of auxiliary low-temperature power plants. The following low-temperature cryogenic substances were chosen for the power plant operating according to the Rankine cycle: argon, difluorochloromethane, trifluoromethane, tetrafluoromethane, ethylene, ethane. For the power plant operating according to the Brayton cycle we chose ethylene, trifluorochloromethane, tetrafluoromethane. According to the results of calculations, as well as according to the results of analyzing the dependence of power on the degree of increasing the pressure, we suggest several cryogenic substances that show the best performance among the considered working fluids.
El repliegue de tropas de Estados Unidos en el mundo

En las últimas décadas se ha registrado un descenso en el número de tropas estadounidenses desplegadas a nivel mundial. Algunos análisis relacionan esta tendencia con una pérdida de capacidades militares y un declive de la hegemonía de Estados Unidos. No obstante, consideramos que debe observarse una complejidad mayor relacionada con algunos procesos que impactan en la lógica de repliegue, específicamente tres. Primero, el cambio en la lógica operacional hacia un unilateralismo en la acción, tendiente a liberar el actuar militar de Estados Unidos de constreñimientos políticos, diplomáticos y sociales. En segundo lugar, una serie de reajustes posfordistas en el ámbito militar, resultante de las reestructuraciones posteriores a la crisis económica de la década de 1970, que se hacen acompañar de diversas innovaciones derivadas de los avances e innovaciones tecnológicas de los últimos decenios, específicamente la utilización de drones. Tercero, una creciente resistencia que se opone a la presencia militar de Estados Unidos en distintos territorios fundamentales para la proyección mundial estadounidense. De esta manera, el repliegue, si bien responde a un declive relativo, es también signo de una forma de despliegue distinto y una lógica ofensiva transformada, correspondientes a la conflictividad del siglo XXI.
Leadership and Emotional Intelligence during a Crisis
Authors: Aguilar Yuste Manuel
Published: January 2022

Currently, a company’s success not only depends on having the capital, tools, knowledge, and services to offer to a specific audience. It depends mainly on the emotional intelligence of its organizational leaders to achieve harmony in leader-team interpersonal relationships and fulfill its goals and objectives. Therefore, it is pertinent to contribute to this field of research by exploring the environment where these types of human relationships occur. Managerial leaders who apply emotional intelligence strategies make a company’ excellent management visible and viable; these leaders are responsible for influencing others, molding groups as needed. The daily interaction between leader and employees is dynamic, and one way or another arises from following certain types of leadership found within the structure. Nevertheless, we are living in challenging times due to a global pandemic, where new emotions and skills must be managed, particularly by the leader. Any event of this magnitude has its consequences, especially if we talk about a virus that has caused a health crisis and continues to cause the death of thousands of people. These repercussions encompass several areas, such as the economy, health, education, and society. Albert Einstein used to say that the tone of the century is set in its first twenty-five years, so it is essential to build the foundations of a new society marked by new social leadership.

A kötöttpályás közlekedés szerepe Budapest keleti agglomerációjának fejlődésében
Authors: Erdei Attila
Published: January 2022

A közösségi közlekedési rendszerek fő funkciója a mobilitás. Ezzel lehet biztosítani a versenyképességet, a megfelelő életminőséget és a kohéziót a társadalom számára. A közlekedési rendszerek legfőbb szereplői az utasok, a szolgáltatók, illetve a döntéshozó, hatósági szerepet betöltő szervezetek (pl. állam, önkormányzatok, szakhatóságok). Budapest keleti agglomerációját ma és a múltban is sűrűn behálózzák a vasúti és a HÉV pályák. Budapest agglomerációjának közlekedési térképét tanulmányozva jól látható, hogy a terület két fontos „gerince” a gödöllői HÉV-vonal, és az azzal szinte hurkot képező 80a számú MÁV vasúti fővonal (Budapest-Hatvan). A helyiérdekű vasutak történetét áttekintve felfedezhetők további vonalak létezésének bizonyítékai, amelyek egykor szintén jelentős hatással voltak a régió gazdasági és társadalmi fejlődésére. Kutatásomban fő célom megvizsgálni, hogy milyen hatásai voltak/vannak a kötöttpályás közlekedési rendszereknek a budapesti agglomeráció ezen részének fejlődésére.

A tanulmány célja a magyarországi nők vállalkozási hajlandóságának elemzése strukturált interjúk készítésével és elemzésével, melyet a jövőben kibővítenénk több válaszadó felkutatásával. Feltevésünk szerint hazánkban a nők kevésbé hajlandóak vállalkozást indítani, mint a férfiak, aminek a hátterében az egyéni tényezők és az alacsonyabb önbizalom szerepelnek. Hipotézisünk bizonyítására a nők munkaerő-piaci elméleti irányzatainak áttekintése után interjúkat készítettünk vállalkozó nőkkel. Az eredmények alapján elmondható, hogy a női vállalkozási kedvvel nincs probléma, de a jogszabályi környezet és a túlzott bürokrácia miatt sokan nem mernek belevágni egy új vállalkozás indításába.

Authors: Takács Péter
Published: January 2022

The demand for change of location could be emphasised of all the factors of urban development, as it constantly exists in societies even if for different purposes. Mobilisation provides the background of the engine that operates the economy and the society, its role is to realise the movement of persons, goods and services. The key driver of the urbanization, emerging due to the geographic concentration and coordination of economic and social activities, is the changes in the transport system. Physical characteristics of the cities and their changes have a great impact on the development of the transport system. Due to its good environmental impacts, favouring urban rail networks is clearly targeted in urban planning today. With regard to the availability of cars and the schedules, concerning the increased and changing performance requirements, companies that operate tram services seek optimization opportunities primarily in order to reduce expenses. Conformity between transport development and urban development shall be continuously ensured if we wish to prevent fault-lines in the development of the city, however, realization of them has to be matched with the operator’s intentions for optimization. Considering these aspects on the long run serves the creation of a better economic, social and spatial structure at the settlement concerned, thereby improving sustainable living standards.
Európai Uniós forrásból támogatott munkaerő-piaci képzések területi eloszlása Borsod-Abaúj-Zemplén megyében
Authors: Hajdú Dávid
Published: January 2022

A tanulmány az álláskeresők munkaerő-piaci képzésének területi sajátosságait mutatja be a 2015 és 2019 közötti időszakban Magyarországon, különös tekintettel Borsod-Abaúj-Zemplén megyére és annak járásaira, amely a PhD kutatásom mintaterületét képezi. A statisztikai adatbázisokon alapuló szekunder kutatás az OSAP 1665 Statisztikai Felületen elérhető információk feldolgozásával valósult meg. A kutatás fő célja, hogy hiteles képet kapjunk az álláskeresőknek szóló munkaerő-piaci képzéseken résztvevőkről egy relatíve magas munkanélküliségi mutatókkal rendelkező térségben. Az Európai Unió által támogatott képzések többsége kompetenciafejlesztő tréning, amelyek nem adnak szakmát. A nem szakmát adó képzések nem közvetlenül segítik elő a munkaerőpiacra való visszajutást. A rurális térségekben olyan képzések lebonyolítása lenne a legfontosabb, amelyek elősegíthetik a vállalkozóvá válást, ezzel is hozzájárulva az elmaradott vidéki térségek erősödéséhez. Az álláskeresőknek szóló képzések leginkább a megyei jogú városokra koncentrálódnak, ami tovább hátrány a vidéki térségek lakói számára. A centralizáltság Miskolc esetében is markánsan megnyilvánul, a megyeszékhelyhez közelebb fekvő nyugati járások pedig egyébként is kedvezőbb helyzetben vannak, mint a keleti fekvésűek.

Authors: Járdány Krisztián
Published: January 2022

A borrégióknak a magyar szőlő- és borágazatban betöltött helyzetük vizsgálata nem nélkülözheti a hagyományos gazdasági, műszaki, infrastrukturális, természeti, kulturális és társadalmi aspektusokon túl a szőlészeti-borászati szakmaspecifikus elemzéseket sem. A tanulmány célja a Duna borrégiónak a hazai szőlészeti és borászati ágazatban elfoglalt helyzetétének megvilágítása, és ennek alapulvételével a borrégió fejlesztési prioritásainak meghatározása. A célok eléréséhez a vonatkozó szakágazati statisztikai adatok feldolgozását választottam. Az adatokat különböző matematikai módszerek segítségével dolgoztam fel. A statisztikai adatok elemzése területi alapon és döntően idősorosan történt. Fókuszba helyeztem a termőterület adatokkal, a szőlőhozamokkal és borhozamokkal, valamint a vizsgált területi egység borászati üzemeivel kapcsolatos változók trendszerű vizsgálatát. Az eredmények kiértékelése során megállapítást nyert, hogy a Duna borrégió szőlészete és borászata Magyarország többi borrégiójához képest 2016-tól teljesen eltérő fejlődési pályán halad. Bebizonyosodott, hogy a Duna borrégióban az országos átlagméret feletti nagyüzemi borászatok tevékenykednek, és a feltárt folyamatok trendszerűen ezen borászatok térhódításának kedveznek.

Cultural differences and innovativeness are multi-faceted social phenomenon with innumerable manifestations. Majority of studies have indicated the positive impact of culture. There are some research findings which concluded that culture has a negative impact mainly due to language barriers of diverse cultural workforce which led to low level of communication, in turn led to low level of innovation. Hence the impact of culture on innovation and economic development is debated. Innovation takes place as an art of exercises routed into cultural view points and attitudes. With European Union struggling economies and financial crises, social integration and human capital mobility are key solutions to create innovation and innovative solutions. This study is, therefore aimed at examining the impacts of workplace cultural differences (in a form of human capital mobility) on innovation and economic growth in Europe. Accordingly, Germany, France, Belgium, and Luxembourg were purposively selected based on the higher number of diversified workforce available in companies located in these countries, in order words human capital mobility. Hence, data was collected using a questionnaire random sample of 392 employees (98 from each country) were selected. Consequently, though small portion of the respondents mentioned the negative impact of cultural diversity, the majority of the respondents and the results of the in-depth interview implied that cultural diversity brings people together and enables them to be creative and enhance their innovative performance. Mobility of skilled human capital is an attribute of culturally diverse workforce in a certain company which enable them to share knowledge and skills which in turn improve their innovative capacity. Therefore, this study concluded that cultural diversity has a significant positive impact on innovation and hence on the economic growth. But the barriers that may be seen at workplace due to cultural differences should be properly managed and prior training sessions to newly employed personnel and a platform where all the employees can get an opportunity to introduce themselves and ease their communication should be arranged.

Published: January 2022

In this paper, the effect of the Syrian war on the export of SMEs in Hatay province, located on the Syrian border, is investigated and the role of KOSGEB (SME Development Organization of Turkey) is discussed. For the analysis companies were selected from Hatay. The examined population consists of 1176 exporting enterprises which does export and the sample size was 107 units. Furthermore, an attempt is made to identify the relevant factors causing problems for the SME’s, namely if their country of origin, area of activity, export-orientation and export-intensity was a distinctive factor. It was found that export volume and KOSGEB’s subsidies was a significant factor in explaining business disruption, but other factors turned out to be irrelevant. This lead to the conclusion that the role and activity of KOSGEB (e.g. detailed company analyses, foreign market analyses, regional research and KOSGEB support) should be expanded to more companies.
Changes in the territorial distribution of population and job seekers with higher education in Hungary
Authors: Győri Tímea
Published: January 2022

The study uses different statistical methods to examine the change in the territorial distribution and concentration of the tertiary-educated population and the unemployed between 2001 and 2019. Among the known regional inequality indicators measuring regional disparities, the Dual index and the Hoover index were used. With the help of the location quotient (LQ), the representation of those with higher education in relation to the average was explored and represented at the settlement level. Territorial autocorrelation was performed to more complexly examine the distribution and concentration of tertiary graduates within the population and the unemployed. Spatial neighborhood impact was analyzed using the Global and Local Moran Index. The autocorrelation confirmed regular spatial arrangements in the spatial distribution of tertiary graduates. The study explores whether different weighting of raw data affects the result of autocorrelation, furthermore determines the differences between the location quotient and the GIS representation of Local Moran I.
