Authors: Yessymkhanova Zeinegul , Azretbergenova Gulmira , Saparova Ainura
Published: January 2024

The relationship between economic growth and the environment is an issue that economists have emphasized in recent years. As the effects of environmental problems such as global warming, air pollution, increased use of natural resources, and CO2 emissions have been felt especially since the 1990s, environmental and energy issues have become of primary importance in the field of economic growth in international platforms. For this reason, environmental problems constitute the main agenda in the international arena today. The work of Kuznets (1955) has an important place in this field. In this study, it is aimed to test the Environmental Kuznets Curve hypothesis for the period covering 1980-2021 in BRIC (Brazil, Russia, India and China) countries. For this purpose, panel cointegration analysis was performed in the study, and according to the results, it was observed that the EKC hypothesis is not valid for BRIC countries and there is a U-shaped relationship between economic growth and CO2 emissions.

Published: January 2024

Today, coal is the main source of energy in both developed and developing countries. The use of coal fuel for power generation and industry continues to increase. This research will discuss the closing price relationship model for the share prices of two coal companies in Indonesia, namely ABM and IND_E, from January 2018 to July 2023. The modeling used is a multivariate time series approach. From the results of the data analysis, the best model that fits the data is the VAR(3)-BEKK GARCH(1,1). Based on this best model, further analysis of Granger causality, impulse response function (IRF), and forecasting for the next 30 periods as well as the proportion of prediction error covariance are discussed.
A Framework on Setting Strategies for Enhancing the Efficiency of State Power use in Thailand’s Pursuit of a Green Economy
Authors: Sutthichaimethee Pruethsan
Published: January 2024

The objectives of this study are to investigate the efficiency of state power use in governing the country towards a green economy and to examine proactive strategies to enhance the efficiency of state power use. This study employs a mixed-methods research approach, including quantitative research involving the construction of a model, SEM-LCM-VECM, to assess the above efficiency. Additionally, the findings from quantitative research are integrated into qualitative research to formulate proactive strategies for exercising state power to foster sustainable development. The findings indicate that the use of state power for the development of a green economy, in accordance with the 20-Year National Strategic Plan and various development strategies of Thailand, has proven to be inefficient. This inefficiency stems from continuous growth in the economic and social sectors, while the environmental sector has consistently deteriorated. The most significant contributing factor directly impacting the environment is the economic sector, followed by the social sector. Moreover, Thailand's adaptability towards sustainability has been notably slow and falls below the established standards. If the government continues to use state power and pursue policies in a manner similar to the past, it is likely to have severe adverse consequences for the environment. This is due to the fact that reactive measures, including civil measures, administrative measures, and criminal measures, cannot effectively facilitate the development of a green economy. Therefore, the guidelines for addressing and formulating proactive strategies are of paramount importance and highly necessary for achieving sustainability. Research findings suggest that the government must establish reactive measures alongside proactive measures in economic aspects. These measures include 1) taxation and revenue collection; 2) subsidies and tax incentives; 3) financial enforcement incentives; 4) deposit systems and refund mechanisms; and 5) ownership and market creation systems. The study also reveals that countries efficiently implementing these economic measures for sustainability include European nations and Asian countries such as South Korea and Japan. Consequently, Thailand should consider applying the research findings to appropriately and efficiently shape the use of state power before the nation causes further irreparable damage. It is imperative that these proactive measures are pursued diligently and continuously to promote green economy policies and ensure sustainability in both the present and future.
CO2 Emission and Research and Development Relationship for Azerbaijan
Authors: Huseynli Nigar
Published: January 2024

Countries take different measures to reduce environmental pollution. Countries sometimes choose taxation as a method for environmentally friendly production and consumption activities. On the other hand, they also make additional environmental expenditures to protect the environment. The method and implementation of the decisions to be taken differ from country to country. In this study, the relationship between CO2 emissions and government R&D expenditures for Azerbaijan is examined. In the study, causality analysis was carried out using annual data for the period 1998-2022. After performing the necessary assumption tests in the analysis, the Granger method was preferred. According to the findings of the study, no causal relationship could be determined between R&D expenditures and CO2 emissions. In other words, there is no causal relationship between these variables.
Corruption and Environmental Damage: Evidence from Panel Data in ASEAN-6
Authors: Ikhsan Ikhsan , Amri Amri
Published: January 2024

Environmental damage is a topic of great concern among researchers and receives special attention in global circles. One of the major contributors to environmental damage is the emission of greenhouse gases, such as carbon dioxide. In this research, the influence of corruption on carbon emissions in six ASEAN countries is investigated, using indicators of economic growth, renewable energy, and urbanization. The Fixed Effect Model is used as the method of analysis, and the research data used is from 1996 to 2019, based on its availability. The research findings suggest that there is an existence of Environmental Kuznets Curve (EKC) in the form of an inverted U relationship. Renewable energy has a negative effect, while urbanization has a positive effect on carbon emissions. Additionally, control of corruption has been found to have a positive effect on carbon emissions. Based on these findings, it is essential to promote maximum economic growth, use renewable energy, limit urbanization, and increase control of corruption to help mitigate carbon emissions and environmental damage.

Published: January 2024

In recent years, Indonesia has grappled with a notable surge in public debt, underscoring the urgency of prudent fiscal management. This study employs the Autoregressive Distributed Lag (ARDL) method to investigate the long-term connections between key variables, including gross domestic product, gross domestic investment, gross domestic savings, carbon emissions, and technology, using data from 1990 to 2020. Our findings reveal a significant and negative association between savings and environmental degradation with Indonesia's public debt. These insights bear substantial policy implications, emphasizing the importance of integrating environmental considerations into economic planning and suggesting that the banking sector could enhance fiscal stability by incentivizing increased savings rates. This study provides valuable guidance for policymakers and economists seeking to foster Indonesia's economic resilience in the face of mounting public debt.

Authors: Yesbolova Ainur Yergazievna , Abdulova Tolkyn , Nurgabylov Murat , Yessenbekova Sapargul , Turalina Svetlana , Baytaeva Gulnara , Myrzabekkyzy Kundyz
Published: January 2024

This study aims to analyze the impact of energy consumption and industrial production on CO2 emissions in the Turkic Republics using the Panel Data method for the period 2000-2020. However, Turkmenistan was excluded from the analysis because the relevant data could not be accessed. Data from Kazakhstan, Azerbaijan, Kyrgyzstan, and Uzbekistan were analyzed. CO2 emission creates problems in terms of environment and sustainability and is a parameter that all countries and international organizations carefully monitor and try to reduce. Using panel data regression, this study examined whether renewable energy and industrial production and countries impact CO2 emissions. The findings revealed that as renewable energy consumption increases, CO2 emissions decrease. However, the effect of industrial production on CO2 emissions was not statistically significant. These results demonstrate that the industrial development of selected countries does not pose a CO2 emission problem. A comparison of countries showed that the high CO2 emission value for Kazakhstan was also reflected in the panel data regression findings, and among the four countries, the country effect was positive only for Kazakhstan. This study is noteworthy in revealing the effect of renewable energy consumption on CO2 emissions. To reduce CO2 emissions and gain a better understanding of the impact of renewable energy consumption on CO2 emissions, future studies should include both developing countries and OECD countries, and compare the results obtained from them.

Authors: Avazkhodjaev Salokhiddin , Dhiensiri Nont , Mukhamedov Farkhod
Published: January 2024

This study investigates the long-run and short-run nexus between renewable energy investment, and Islamic and conventional stock markets in advanced economies, namely the United States, United Kingdom, and European Union over the period from January 1, 2002 to August 1, 2023. The study uses the Nonlinear Autoregressive Distributed Lag (NARDL) model to examine the long-run and short-run asymmetric effects between selected variables under study. The results of empirical model estimation suggested that the green energy investment adjustment is running towards the long- and short-run steady increment regarding positive and negative shocks in conventional and Islamic stock markets. Indeed, the shocks of the green energy investment on conventional stock markets of the US and EU are positively asymmetric in the long run; the UK has an insignificant effect in the long run. Importantly, green energy investment positively has significant effects on conventional and Islamic stock markets in the US. UK and EU (except the conventional stock market of the US).  The short-run coefficients of green energy investment have a  significant positive effect on Islamic stock markets for the selected U.S, UK, and EU markets. Likewise, the EU conventional stock market has a significant positive effect in the short run. Change in green energy investment has a negatively insignificant impact on Islamic and conventional markets of the EU and the UK.  Indeed, short-run coefficients of green energy investment negatively on the U.S. conventional stock market. The increase in green energy investment may result in an increase in the cost of energy generation, which reduces the renewable energy production firm’s profitability and finally decreases the stock market prices in the short run. These findings have important implications for the portfolio diversification and hedging decisions of environmentally concerned investors. In sum, investors should consider the presence of extreme tail dependence between green investments and stock markets an important factor in making more informed and rational choices.

Published: January 2024

The article provides an empirical analysis on the impact of renewable energy development on the unemployment rate, agricultural output and relative rural population in Ecuador. Using an empirical approach, the study examined how the production and consumption of this energy affects the labor market in rural regions. To this end, relevant data on the development of renewable energies in the context of Ecuador were collected, and statistical analyses were carried out to evaluate the relationships between these and the variables of interest. The results obtained indicate that the development of renewable energies has can reduce the unemployment rate and has a positive effect on the relative population of rural regions, however, it does not seem to significantly affect agricultural production. These findings support the idea that the production and consumption of renewable energies can generate jobs directly, due to the need for workers for the construction and maintenance of these technologies, and indirectly, through cheaper energy, increased productive efficiency and better conditions for the expansion of companies. The study offers a significant contribution to the field of energy economics in developing countries and highlights the importance of the adoption of renewable energy sources for rural regions.

Authors: Sharma Aarti Mehta , Baby Saina , Raghu Varsha
Published: January 2024

According to International Energy Agency (IEA), India is expected to surpass China by 2024 to become the second largest consumer of oil in the world followed by the United States. High-Speed Diesel (HSD) has the biggest share in the total petroleum products consumed in India accounting for around 38% of the total consumption. Considering the volatile global oil market and an oil import dependency ratio of more than 80% during the last four years, the probability of supply disruptions is high in the Indian context. As any uncertainty about the supply of diesel can affect the smooth functioning of the economy and may create inflationary pressures. Accurate forecasting of HSD demand will be essential for appropriate supply management arrangements. Artificial Neural Networks (ANN) with Multi-Layer Perceptron (MLP) and extreme learning machines is used for forecasting diesel demand in this study. Demand forecasting has been carried out using monthly HSD demand data drawn from the “Indiastat” database for the period 1991-2022. Comparison of ANN with traditional forecasting methods of Autoregressive Integrated Moving Average(ARIMA)and Exponential Smoothing has also been undertaken in this study. This study identifies the deep learning technique of ANN with MLP as the best diesel demand forecasting technique.
Hogyan látta az FBI-t az 1950-es évek eleji magyar rendőrség?
Authors: Papp Dávid
Published: January 2024

Az Egyesült Államok Szövetségi Nyomozó Irodája 1950-re már több mint 40 éves múltat tudott maga mögött. A második világháború után a világot és Európát a hidegháborús helyzet keletkeztette megosztottság, rivalizálás jellemezte. A vasfüggöny két oldalán uralkodó ideológia éles ellentétjei kétségtelenül kihatottak a rendőrségektevékenységére, felfogására, befolyásolták a szakmai állásfoglalást, nézeteket. Mindkét oldalon jellemző volt ekkoriban a bűncselekménnyel nem gyanúsítható politikai aktivisták üldözése. A szovjet blokk nyugati szélén elhelyezkedő Magyar Népköztársaság államrendőrsége lehetőségeihez mérten élesen bírálta a kapitalista államok rendőrségeit, kiváltképp az Egyesült Államok Szövetségi Nyomozó Irodáját. Már az 1953-ban létrejött Rendőrségi Szemle folyóirat első évfolyamaiban megjelenő rendőr szakcikkek között is találunk több olyat, amely részben vagy egészben az FBI tevékenységével foglalkozik, pontosabban bírálja azt, némelyik közülük visszautal az elmúlt évekre.
A tálib kormányzati válság
Authors: Katona Magda Nasrin
Published: January 2024

A tálib államelmélet kidolgozatlan, a politikai rendszer sem meghatározott. 2021. augusztus 15-én elfoglalták a fővárost, Kabult, majd az egész ország az ölükbe hullott, a tálibok az 1996–2001 közötti Iszlám Emirátusukat újra bevezették, ám nincsen definiálva, hogy az milyen elvek alapján és mi módon működik. Ez a meghatározatlanság és a kidolgozottság hiánya eltérő értelmezéseknek nyújt lehetőséget, ami különböző hatalmi centrumok felemelkedésének ad teret: Haibatullah emír kandahári tanácsa, a Hakkáni-hálózat, valamint Baradar molla és Jákúb molla csoportja fémjelzik ezeket a hatalmi központokat. A tálib rezsim jövője e hatalmi központok egymáshoz való viszonyának alakulásától függ. Az általuk ellenőrzött területeken a tálibok a helyi közösségek révén, katonai-civil tanácsaik horizontális hálózata révén sikeresen, ám korántsem egységesen kormányoznak. Tanácsaik tevékenységében nem váltak el az államhatalom különböző ágai. Döntéshozóként, bíróságként, valamint kormányzati szervekként egyaránt sikeresebben működtek a hadurak és „kutyamosók” szövetsége által működtetett köztársasági kormány korrupt szerveinél. De ma már a tálibok a társadalmat szétforgácsoló centrifugális tendenciák visszaszorítására vallási diktatúra bevezetésével reagálnak. A tálibok kormányzása gazdasági téren nem mutat rossz képet. Világi és vallási adókból (’usr, zakát), vámokból, illetékekből, szabálysértési jövedelmekből az állam jelentős bevételekre tett szert. Fontos bevételi forrás az ópiumgazdaság, valamint a fegyverek és a műkincsek csempészete is. A centrifugális erők, a radikalizmus, a terrorszervezetek, bűnözői szindikátusok térnyerésével a tálib kormányzat számos kihívással szembesül. Ezeknek a kezelése során a tálibok frakciói különböző megközelítési módokat és praktikákat alkalmaznak, ami előbb-utóbb törést okoz soraikban. Életképes alternatívájuk azonban nincs. Túlélésük záloga, ha hatalmi belharcaik során a mérsékeltek kerülnek ki győztesen, és kooptálják a kormányzásba a társadalom különböző csoportjait.
A radikalizálódás okai
Authors: Pupos Csaba
Published: January 2024

A globalizáció hatására azok a határok, amelyek a múltban oly egyértelműen felosztották a világunkat, egyre halványulnak. Főként Észak-Amerikára és Nyugat-Európára jellemző az a tendencia, hogy az ott élő kisebbségek száma rohamosan növekszik, és ennek elkerülhetetlen hozadéka az, hogy az adott társadalom folyamatos változáson megy keresztül. Be kell látnunk, hogy az integráció nem egyirányú, a kisebbséget alkotó csoportok is hatással vannak az ország eredeti lakosságára. Ez a kétirányú folyamat közel sem nevezhető zökkenőmentesnek. A kultúrák közti szakadékok egyre mélyülnek, és fokozatosan kialakul egy párhuzamos társadalom, ahol az egyének nem az állami döntéshozó szervek joggyakorlatára támaszkodnak, hanem sokkal inkább saját hagyományaikra és egymás közül kiválasztott vezetőikre, és a hétköznapokban kialakult problémáikat az ő iránymutatásaik segítségével igyekeznek megoldani. Tovább duzzasztja a problémákat az, hogy a kulturális és gazdasági különbségek miatt egyre több, zömében bevándorló háttérrel rendelkező állampolgár szorul a társadalom peremére, ami kiváló táptalajt biztosít a radikalizálódási folyamatoknak. E jelenség okozta problémák megoldása nem várható el csupán a rendészettől. Ez egy olyan komplex feladat, amelyben számos tudományág és társadalmi szereplő összehangolt munkájára van szükség. Először is meg kell értenünk a gondok kialakulásának a körülményeit és lefolyásukat. Több neves pszichológus és szociológus munkásságát alapul vehetjük ahhoz, hogy kialakítsunk egy olyan teljes képet, amely segíthet a rendelkezésre álló anyagi, technikai és humán erőforrás helyes elosztásában, és így támogathatja az integrációs folyamatokat.
Gondolatok az információ szerepéről – más, egyéni szemszögből
Authors: Bács Zoltán György
Published: January 2024

Az információ mint kifejezés a mindennapunk, munkánk, életünk egyik leggyakrabban használt kifejezése. Használata során nem mindig vagyunk tisztában eredetével, jelentésével, és végig sem gondoljuk, hogyan keletkezik az információ, mi az alapja és milyen tulajdonságai vannak. Nem vetünk számot azzal sem, hogy az információ állandónak tekintendő vagy változhat bizonyos körülmények között. Jelen tanulmány célja – kapcsolódva a már korábban az információ alkalmazásával foglalkozó tanulmányokhoz – feltárni az információ mint jelenség néhány, a rendvédelmi, biztonsági, nemzetbiztonsági és terrorelhárítási területen való alkalmazása során kiemelkedően fontos jellegzetességét.
Additív eljárással készült lineáris vágótöltetek működésének vizsgálata
Authors: Ember István
Published: January 2024

Napjaink egyik rohamosan fejlődő területe a 3D nyomtatás, amely több évtizedes múltra tekint vissza, mégis csak most lett széles körben elterjedt. Az additív eljárások sok lehetőséget biztosítanak alkatrészek készítésére. Az egyik ilyen terület, ahol alkalmazni lehet ezt a gyártási módszert, a robbantástechnika. Az egyedi töltetek és a kumulatív robbantási feladatok területén jelentős mozgásteret ad ez a technológia, azonban az alacsony sűrűségű alapanyagok esetében nem minden részterületen rendelkezünk kellő tapasztalattal. A bemutatott tesztben sikerült több ilyen töltet működését megvizsgálni robbantás után a céltárgyak elemzésével. Többek között az optimális vágáshoz szükséges távolságot is sikerült azonosítani, ami hasznos ismeret lesz a további töltetek tervezésénél.
Az autonóm közúti gépjárművek kiberbiztonsági aspektusa és társadalmi megítélése (1. rész)
Authors: Katona Gergő
Published: January 2024

A beépített technológiai megoldások és a vezeték nélküli képességek elterjedésével a mai járművek már nem elszigetelt mechanikus gépek. Egy összekapcsolt rendszer részévé válnak, amelyben folyamatosan kommunikálnak a járművek egyes rendszerelemei egy belső hálózatban, továbbá a járművek egymással és a forgalomirányítási központtal egyaránt. Ezen összekapcsolt adatok halmazát nevezzük önvezető közlekedési eszközök irányítási rendszerének. Ez a rendszer képes támogatni az autonóm közlekedés jövőbeli bevezetését, és a mesterséges intelligencia használatával jelentősen javítani lehet a közlekedés biztonságát, hatékonyságát és fenntarthatóságát. Az autonóm közlekedési eszközök megjelenése azonban új biztonsági kérdéseket vet fel, amelyek az egész rendszert potenciális célponttá teszik a kiberbiztonsági támadásoknak, ezek pedig mind a közlekedés biztonságát, mind pedig az emberi életet veszélyeztethetik.
A koronavírus idején a közösségi médiában megjelenő álhírek elemzése, az „infodémia” fontossága
Authors: Molnár Ákos Ádám
Published: January 2024

2019. decemberben Kína egyik tartományában, Vuhanban jelent meg a napjainkra már mindenki által ismert és azóta világjárvánnyá nyilvánított Covid–19. A vírussal együtt azonban felerősödtek az álhírek és az ezzel kapcsolatos dezinformálás. Az álhírek és azok terjedése több csatornán is meg tud valósulni, napjainkban a legerőteljesebben az online térben. 2020 tavaszán a World Health Organization az „infodemic” kifejezéssel – azaz amikor túl sok információ, köztük rengeteg megtévesztő jelenik meg egy járvánnyal kapcsolatban – mutatott rá, hogy nemcsak a vírus, de a vele kapcsolatos dezinformáció, vagyis félreinformálás is ugyanolyan mértékben terjed a világon. Jelenleg még mindig ebben a korszakban élünk, a „post-truth” árnyékában, amikor a különböző híreket gyakrabban hisszük el az érzelmi töltöttségük, mintsem valóságtartalmuk vagy forrásuk alapján, jelentősen befolyásolva a társadalom informáltságát. Kutatásom fő célja a koronavírussal kapcsolatos álhírek és érzelmek vizsgálata. Ezen belül az álhírek terjedését és a hallgatóságra tett hatásait vizsgáltam. Online felületeken végzett kulcsszóelemzést alkalmazva az álhírek terjedését, annak ütemét és miértjét kutattam.

Egy kísérleti kavitációs berendezés tervezésével, létrehozásával és kisüzemi alkalmazásával a szennyezett vizek egyik lehetséges tisztítási módját vizsgáltuk. A kísérleti berendezés mobil kivitelű, és alkalmas különböző szennyezettségű vizek tisztítására. Bemutatjuk a kavitáció hatását különböző mikroszkopikus méretű élőlényekre. Először egy hígított zöldalgatenyészetet vizsgáltunk, megállapítottuk, hogy 16–32 perces kavitáció több mint 10–20%-kalcsökkenti a klorofillkoncentrációt és az ép sejtek arányát. Biológiailag bontható szennyvízzel kevert algás halastóvízben, kavitáció hatására a cianobaktériumok, ostoros algák mennyisége 40–80%-kalcsökkent, a zöldalgáknál minimális volt a csökkenés. Ezeknél a méréseknél síkszelepes, nagynyomású kavitációgenerátort alkalmaztunk. Bizonyítottuk,hogy a hajók ballasztvize és a szennyvizek mikrobiótája mennyiségének csökkentésére a kavitációs vízkezelés ígéretes megoldásnak tekinthető, de figyelemmel kell lenni arra, hogy csak elpusztul a mikrobióta, de nem tűnik el a vízből.
Szennyvízkezelés a múltban és a jelenben
Authors: Györki Gábor
Published: January 2024

Az emberiség történelmében több ezer éve fontos szerepet játszik a szennyvíz kezelése. Kezdetben csak a higiéniai feltételek biztosítása miatt volt rá szükség, a népesség és az ipari termelés növekedésével azonban a szennyezők kibocsátása már a természetes környezetet is fenyegeti. Amióta érzékelhetők a szennyezés hatásai, illetve kifejlődtek megbízható analitikai módszerek, mind a kutatás-fejlesztés, mind a törvényhozás egyre nagyobb figyelmet szentel a környezetvédelemnek, a szennyvíztisztításnak, a szennyvíz-újrafelhasználásnak. Jelen tanulmány a releváns szakirodalom áttekintésével szeretne átfogó képet adni arról, hogyan jutott el a szennyvízkezelés a történelem során a pillanatnyi állapotába.

Markov-láncok alkalmazása az aszályos napok valószínűségének megállapítására Budapest térségében
Authors: Jánosi Andrea , Fekete Árpád , Szám Dorottya
Published: January 2024

A klímaváltozás egyik hatása hazánkban az aszályos időszakba eső napok számának növekedése. Ennek következtében egyre nagyobb szükség van a hatékony csapadékvíz-gazdálkodásra, valamint a hőhullámok elleni védekezésre. Budapest térségének csapadékadatait felhasználva becslést adunk arra, hogy a jövőben mekkora eséllyel fog egy nap aszályos időszakba esni. Egy viszonylag új vizsgálati módszert, a Markov-láncok elméletét használtuk fel a budapesti csapadékadatsorok elemzéséhez. Hipotézisvizsgálattal azt is bizonyítottuk, hogy az aszályos időszakok között eltelt idő exponenciális eloszlást követ.

The role of iconography in shaping Chinese national identity: Analyzing its representation in visual media and political propaganda
Authors: Zhen HuiXia , Han Bo
Published: January 2024

The creation of cultural iconography that may reflect national culture and encourage individuals to identify with Chinese culture has always been a difficult issue. In this study, we present a symbolic creation framework for Chinese national cultural identity constructed from visual pictures using generative adversarial networks (GAN). To enhance the structure collapse phenomena of generative adversarial systems, form search regular procedure and generator cross-loss factors on the basis of GAN should be combined. To enhance the real-time efficiency of the model by lowering the parameters in the model, the conventional convolutional component of the generator in the system’s architecture is substituted with a significant recoverable convolution. The notions of iconography and character as they relate to symbols are discussed in this essay.  It also advises using iconography as a technique of symbolic imagery to give emergent symbols identity.  The design in this study may create significant performance ethnic cultural symbols while preserving superior temporal performance, according to the findings of rigorous testing on real datasets, which may have practical application value. The accuracy, precision, recall, and F1 of the system in this study are 91.54%, 89.02%, 90.96%, and 87.48%.
