The effect of prenatal stress, post-traumatic stress disorder, and their combined effect in rat mothers on the condition of the pituitary-adrenal system and the brain redox balance in 20-day-old embryos was studied. Mother’s prenatal stress result in increase the level’s corticosterone in the blood and decrease the level of reduced glutathione in the brain of male embryos. In female embryos, the level of Fenton-induced products of proteins oxidative modification increased and the reduced glutathione level in the brain decreased. Modeling of post-traumatic stress disorder in mother result in an increase in the corticosterone level in the blood, and a decrease in the level of Fenton-induced products of proteins oxidative modification in the brain of male embryos. In female embryos, the levels of products of spontaneous and Fenton-induced oxidative modifications of proteins in the brain increased. The combined effect of two types of stress in mother result in an increase in levels corticosterone in the blood, a decrease in the spontaneous products level and an increase in Fenton-induced products level of proteins oxidative modifications, and a decrease in the reduced glutathione level in the male embryos brain. In female embryos, all the studied indicators of proteins oxidative modification products in the brain increased. Thus, all three studied types of stress in the mother cause changes in the hypothalamic-pituitary-adrenal system and in the brain redox balance in 20-day-old embryos. These changes are different in male and female embryos, and in most of the studied indicators, the pattern of differences is inverted in relation to the control group. Such changes at embryos can result in negative changes in the neuronal organization in adult offspring of stressed rat mothers.

Alzheimer’s disease (AD) is the most common neurodegenerative disease leading to senile dementia. It is known that the processes of neurodegeneration are closely related to neurotrophic support. In this work, carried out on a model of AD - the OXYS line of rapidly aging rats, CDNF deficiency in the hippocampus was first identified, and an attempt was made to compensate for it by inducing overexpression using an adeno-associated viral construct. The constructs were introduced into the dorsal hippocampus of rats at the age of three months. 15 months after the introduction of the construct, we showed overexpression of CDNF in the target structure, but did not detect its effect on the learning and memory of animals in the Morris water maze, as well as on the accumulation of Aβ and Tau protein and the expression of genes involved in the unfolded protein response (UPR).

Physical activity is well known to have a beneficial effect on whole body functions, whereas a sedentary lifestyle contributes to the development of metabolic and other diseases and can lead to cognitive decline and increased risk of dementia. The hippocampus mainly controls cognitive performance and the hippocampal neurodegeneration is directly correlated with dementia progression. Hindlimb unloading (HU) is a widely used method to simulate microgravity in rodents and can be used as a model of mobility restriction since one of the main factors of HU is muscle disuse. Additionally, rodents show impaired learning and memory after long-term HU. Here, we explored whether HU would affect the survival or death of the hippocampal cells. Our data demonstrated that after 3-day HU, both apoptosis and autophagy were activated in the hippocampus, as evidenced by the activation of caspase 3 and 9 and an increase in the number of Cathepsin D and LC3b double-positive cells correspondently. Our data indicated that HU has no deleterious effects leading to neurodegeneration for up to 14 days. Moreover, our results also showed that the activation of autophagy during short-term HU had a protective effect, as we did not observe any cell loss or damage.

The formation of a conditional connection allows the organism to change its reactions to various environmental factors, combining and mobilizing the necessary internal adaptive processes. It is assumed that there are common mechanisms underlying the formation of adaptive processes – stress response and learning. To develop methods for non-invasive correction of nervous system pathologies at a model object of genetics – Drosophila, the relationship of adaptive mechanisms of the formation of a conditional connection and the development of a stressor reaction to the weakening of the Earth’s magnetic field in light: dark conditions was studied. The role of learning and lighting in overcoming stress in connection with the formation of long-term memory in the paradigm of conditioned courtship suppression was revealed. Within the framework of quantum dynamics of electronic and nuclear spins of transition states of radical molecules, the hypothesis of their participation in the formation of long-term memory is considered.

Domestication profoundly shapes the evolutionary trajectories of both humans and animals. Despite significant scientific interest, the genetic underpinnings of domestication, particularly those related to behavior, remain elusive. This paradox may be reconciled by considering that behavior-associated genes have already been identified but categorized exclusively to other functional groups. Our investigation into this hypothesis utilized goat genome and human brain transcriptome data, focusing on the pigmentation gene KITLG due to its frequent association with domestication. Through analysis of interpopulation covariation between KITLG and candidate genes in the domestic goat genome (Capra hircus), we identified eight genes evolutionarily linked with KITLG. These genes were divided into three functional categories: (i) regulation of the glucocorticoid (GC) signal, (ii) initiation, and (iii) control of structural neuroplasticity. In the human brain, the regional expression patterns of the corresponding transcripts were complementary and most pronounced in areas associated with social interaction. We propose that a mutation in KITLG may decrease the activation threshold for GC-mediated neuroplasticity in these regions, enhancing the processing of social stimuli. The association of this allele with spotted coat patterns likely facilitated its selection, with the uniqueness of the pattern promoting selective social contacts. Consequently, the genomes of domesticated animals is probably more profoundly influenced by behavioral functions than previously believed. Further research could unveil novel functional attributes of the nervous systems in both animals and humans.

Published: December 2024

The ability of crown ether compounds to effectively react with metal ions underlies their practical use. The selectivity of compounds depends on the structure of the ligands in the molecule, the presence of functional groups and donor atoms in it. It is known that the high selectivity of the reagents depends not only on the nature of the donor atoms in the ring, but also on the stability of the ring structure. The preparation of polymers containing a thiacrown ether group is an urgent task, since such groups make it possible to obtain selective sorbents.
The purpose of this work is the synthesis of new selective sorbents containing a thiacrown ether group and the study of their complexing properties with respect to silver ions. To obtain polymers for this purpose, the reaction of the interaction of a gel and a porous copolymer of chloromethylated styrene and divinylbenzene (HMS) with aminobenzothiacrown ethers was studied. Using various influencing factors, it was possible to obtain sorbents with a high exchange capacity (2.5 mmol/g). When studying the sorption of silver(I) ions from aqueous solutions by a supramolecular sorbent with a thiacrown ether group, it was shown that the optimal pH value is 6, the contact time is 60 min. The maximum sorption capacity of the sorbent for silver (I) ions reaches 240.8 mg/g.

ZOR YILLAR: ORHAN VELİ VE METİN ELOĞLU’NUN ŞİİRLERİNDE II. DÜNYA SAVAŞI
Authors: Çetin Seda
Published: December 2024

II. Dünya Savaşı tüm dünyada olduğu gibi Türkiye’de de büyük yıkımlara neden olmuş bir savaştır. Bu yıkımlar, savaşa girmemiş olmasına rağmen maruz kalan Türkiye’de yoksulluk, kıtlık ve salgın hastalıklara neden olurken savaş sebebiyle vurgunculuk, karaborsacılık gibi yollarla bazı kimseler de çok kısa sürede zengin olurlar. Hayatın her alanını etkileyen savaş bu dönemde edebiyata da yansımış, Türkiye’nin savaş sebebiyle yaşamak zorunda kaldığı ekonomik ve toplumsal açmazlar kurmaca eserlere aktarılmıştır. Diğer türlere nispeten kısıtlı imkânlarına rağmen şiir türü de dönemin şairleri elinde savaşın etkilerinin yansıtıldığı bir alan olmuştur. Bu şairlerden ikisi Garip hareketinin öncüsü Orhan Veli (1914-1950) ve onun takipçisi Metin Eloğlu’dur (1927-1985). Onlar ‘alelade insan’a sanatlarında yer vermek üzere yola çıktıkları için savaş yıllarında sıradan insanın verdiği yaşam mücadelesine odaklanmışlardır. Orhan Veli’de ‘alelade insan’ hayattan büyük beklentileri olmayan, kendini olayların akışına bırakmış, tevekkül sahibi, dingin bir insandır. Şair bu dingin ‘alelade insan’ı daha çok orta sınıf şehirli birey olarak kurgular ve ironiye yer verse de genelde sakin bir üslup kullanır. Metin Eloğlu’nun ‘alelade insan’ı ise kentli olabileceği gibi köylü de olabilen ancak fakirliğinin farkında ve bu yüzden oldukça öfkeli bir kimsedir. Şair fakir ve öfkeli bu kimseyi şiirlerinde çoğunlukla zenginlik hayalleri içinde çizer. Bu yüzden onun şiirlerinde kişiler hedeflerine ulaşmak için kolaylıkla yalan söyler, ahlakdışı işlerle kolay yoldan para kazanmaya çalışırlar. Metin Eloğlu’da sövgüye yer verecek kadar kuvvetli olan bu öfkeli söylem onun, Garip hareketi yanında toplumcu gerçekçilikten de yararlanmış olmasının bir sonucudur. Bu çalışma benzer dünya ve edebiyat görüşlerine sahip iki şairin savaş yıllarında Türk insanını şiire yansıtma biçimlerine odaklanmaktadır. Bu sayede dünya tarihinde de önemli bir yeri olan II. Dünya Savaşı bu şairlerin bakış açılarıyla ortaya konmuş, savaş yıllarıyla ilgili şahitlikler şairane bir duyuşla açığa çıkmış olacaktır. Bu inceleme aynı zamanda iddia edildiği gibi ‘alelade insan’ı tam olarak resmetme noktasına hangi şairin daha çok yaklaşmış olabileceğiyle ilgili de bazı tespitlerde bulunmaktadır.

Günümüzde internetin sağladığı paylaşım ortamları iletinin akış hızını ve çeşitliliğini nicel anlamda olağanüstü bir dereceye taşırken herhangi bir denetimden geçmeyen bilgi veya eserin nitelik olarak değerini tespit etmek zorlaşmıştır. Bu durum, bilgi okuryazarlığı ve eleştirel okuma becerisini kazanmamış kişileri “enformatik cehalet” tehlikesiyle karşı karşıya getirmektedir. Oysa okumanın amacı sadece bilgi edinmek ya da eğlenmek değil kişilik gelişimine katkıda bulunmak ve aydınlanmak olmalıdır. Bu çalışmada, gelecek zaman diliminde toplumu inşa edecek olan üniversite gençlerinin okuma kültürü; neyi, neden, nasıl, niçin, hangi motivasyonla ve ne kadar okudukları bir problem olarak araştırılmış, Muğla Sıtkı Koçman Üniversitesi merkez yerleşkesinde öğrenim gören lisans öğrencilerinin okur profilleri ortaya çıkarılmıştır. Araştırmanın anılan üniversitede sözel, sayısal, eşit ağırlık ve özel yetenek puanıyla öğrenci alan 13 fakültede öğrenim gören lisans öğrencileri üzerinde yürütülmesi maksimum çeşitlilik sağlamıştır. Araştırmada elde edilen bulgular, literatürde kişilerin bir yılda okudukları kitap sayısı dikkate alınarak yapılan araştırmalar sonucu ulaşılan “toplumumuzda okuma oranının düşük olduğu” tespitini üniversite öğrencileri örnekleminde de doğrular niteliktedir. Okuma oranının düşük olduğu bir toplulukta okuma kültürünün de zayıf bir durumda bulunması beklenen bir sonuçtur. Bu çalışma ile üniversite öğrencilerinin okuma kültürleri hakkında bir farkındalık yaratılmış ve bunun kendilerinden ya da çevrelerinden kaynaklı nedenleri tespit edilmeye çalışılmış ve çözüm önerileri sunulmuştur. Aileyle başlayan eğitimde, okuma sevgisi ve kültürünün ailede başlayıp öğretmenle devam etmesi gerekmektedir. Ebeveynlerin evde kitap günü benzeri etkinlikler düzenlemelerinin; ilköğretimden yükseköğretime kadar çeşitli kademelerde görev alan öğretmenlerin kitap okuma etkinliklerini ve kütüphane kullanımını teşvik etmelerinin; bireysel ya da belediye, sivil toplum kuruluşu vb. tarafından kurumsal girişimle edebiyat halkaları/okuma çemberleri, etkileşimli ve paylaşımlı okuma atölyeleri düzenlenmesinin toplumumuzun ve üniversite öğrencilerinin okuma kültürlerini geliştireceği öngörülmüş ve önerilmiştir.

Authors: Solehudin Muhamad , Nur Hanifansyah
Published: December 2024

This study explores the impact of Arabic oratory on vocabulary acquisition and public speaking confidence among students in Malaysia, where Arabic is mainly learned for religious purposes. The research aims to assess the effectiveness of Arabic Public Speaking (khitabah) in enhancing language retention and building self-assurance in public speaking through a psycholinguistic approach. Using a mixed-methods design, data were collected from 30 Form Four students at Maktab Mahmud Yan through qualitative interviews, classroom observations, and quantitative pre- and post-tests. The findings show a 20% improvement in vocabulary mastery and a 50% increase in public speaking confidence following weekly oratory sessions. Psycholinguistic strategies, such as voice projection and positive reinforcement, were instrumental in reducing student anxiety. The study introduces a novel integration of Arabic oratory with psycholinguistic techniques, demonstrating a dual impact on language proficiency and confidence. This research suggests that embedding Arabic oratory in language curricula can significantly improve both vocabulary acquisition and speaking skills, offering a holistic method for language development in similar educational contexts.
A Computer Simulation Study on Ion Optics Aiming at the Realization of Projection-Type Mass Spectrometry Imaging
Authors: Naito Yasuhide
Published: December 2024

The projection mode in mass spectrometry imaging (MSI) obtains ion images by retaining the spatial distribution of desorbed ions immediately after their generation as the ion images, then projecting them onto an ion detector of time-of-flight mass spectrometry. Compared to conventional MSI, projection-type MSI can deliver overwhelmingly higher spatial resolution. The mass resolution of projection-type MSI can be improved by a technique named post extraction differential acceleration (PEDA). To assess the feasibility of projection-type MSI with minimal modification of a commercially available laser desorption/ionization time-of-flight mass spectrometer, ion trajectory simulations were performed using the ion optics simulation program SIMION. Under boundary conditions that reproduce the ion acceleration region of the commercial mass spectrometer with a high fidelity, the trajectory simulation results were obtained for a huge number of combinations of ion masses, initial conditions, PEDA parameters, etc. The data analysis provided useful findings that can lead to the realization of projection-type MSI based on the modified commercial mass spectrometer, for instance, the imaging conditions for ion images in the commercial equipment, guidelines for optimizing PEDA parameters, and the effects of differences in PEDA high-voltage rising waveforms.

The objective of this report was to describe the clinical and laboratory findings in an eight-month-old Holstein crossbred cow diagnosed with flying scapula. During anamnesis, the owner informed that the cow was placed in a pasture with other animals of different age groups. Three days after the environment change, he noticed the animal showed abnormal position of the scapulae, reduced appetite, and apathy. He suspected another animal had tried to mount it. The owner also reported it had never happened on his property. Clinical examination revealed difficulty in getting up and reluctance to move. The scapulae seemed to be loose (flying scapula) in a level above the thoracic vertebrae, with noticeable deepening of the rib cage between the front limbs. Laboratory tests showed hypoproteinaemia (5.2 g/dL), selenium values below normal (0.0094 μmol/L), elevated serum creatine kinase (CK) activity (898 U/L), and normal vitamin E levels (7.8 μg/ml) for the species. These findings confirm the diagnosis of flying scapula, having as a triggering factor the trauma associated with selenium deficiency.

This study examines the dynamic connections between electricity generation and agricultural development, utilizing dynamic generalized method of moments (GMM) estimation techniques and annual time series data spanning from 2000 to 2020. The findings offer valuable insights into the impact of electricity generation on agricultural progress. Firstly, both electric power generation and energy generation capacity were negatively and significantly linked to agricultural development in Africa. This suggests that despite increases in electric power and energy generation, agricultural development may not improve due to inefficiencies in the energy infrastructure, including inadequate transmission and distribution networks, unreliable grid connectivity, energy losses, and distribution issues that prevent electricity from reaching rural areas where agriculture is predominantly concentrated. Second, further analysis reveals a significant and positive association between electricity consumption, access to electricity, and agricultural development in Africa. This indicates that expanding electricity access and increasing its consumption in agricultural activities can significantly enhance agricultural productivity and growth across the continent. These results emphasize the importance of improving infrastructure and optimizing capacity utilization to ensure that the growth in electricity generation capacity translates into tangible benefits for agricultural development in Africa. Thus, the study underscores the pivotal role of electricity generation, consumption, and access in promoting agricultural development, while highlighting the need to address infrastructure inefficiencies to achieve sustainable growth.
The Ecosystems Perspective in Energy Research: A New Field is Born?
Authors: Chatzinikolaou Dimos , Vlados Charis , Kokkinaki Angelika
Published: December 2024

The “ecosystem perspective” seems to be gaining importance in energy research. This paper offers a systematic review of 98 articles to shed light on the burgeoning interest in the “energy ecosystems” perspective. The growth in energy ecosystems research stems from several factors: the integration of approaches that connect energy flows with ecological concepts, the inclusion of emerging technologies and socio-technical nuances, and a significant uptick in academic publications over recent years. Our review identifies four pivotal trends shaping the energy ecosystems discourse: “industrial ecology and sustainable development,” “energy transition and socioeconomic evolution,” “business and innovation ecosystems in energy,” “distributed energy systems, smart grid innovations, and associated policy-regulation dynamics.” These trends underscore a pronounced emphasis on energy efficiency in the pertinent literature. Looking ahead, there’s a case for adopting a comprehensive macro-meso-micro framework, with a particular spotlight on the intricate roles of individual energy firms within these ecosystems.

Published: December 2024

The energy landscape, particularly in the electricity sector, is characterised by a complex interplay of various factors that contribute to its inherent volatility. Electricity participants, including investors, regulators, consumers, and policymakers, are constantly seeking methods to better understand and manage the associated risks. The generalised extreme value (GEV) distribution with block minima is applied to model extreme losses on daily electricity demand in South Africa for the period of 1 April 2019 to February 13, 2024. The results of the estimated GEV gave a negative shape parameter implying that both winter and no-winter seasons extremes are correctly model a type III GEV distribution known as the Weibull distribution. When computing the VaR and ES, we found that VaR went as low as 8.74% while for ES had the lowest as 9.57%. Finally, the backtesting procedures further proved that the estimated risk measures are reliable as both the Kupiec and Chrisoffersen tests failed to reject the null hypothesis. In conclusion, the fitted GEV showed some reliance in capturing extremes losses for winter and non-winter returns. Lastly due to reliability of the models, risk analysts together with investors interested in the electricity sector should therefore adopt the procedures used to know the risk of their investment.

Published: December 2024

One of the major concerns for environmental quality improvement is to reduce reliance on fossil energy consumption. However, there is a possibility that economic developments like foreign direct investment (FDI), urbanization, innovation and renewable energy consumption can mitigate carbon emission and curb environmental quality issues. Hence this examines the impact of innovation, FDI, renewable energy consumption and urbanization on the environmental quality of 46 countries for the period of 1990-2021. The study employed pooled mean group auto regressive distributed lag stationarity estimator for the empirical results. The study findings depict that in the long run, trade openness and innovation positively influence environmental quality, whereas FDI does not significantly affect environmental quality deterioration. Renewable energy consumption plays an important role in relying on fossil energy consumption and reducing carbon emissions. This study gives insights into necessary policy endorsements for the sustainability of environment through innovation.

The Colombian government’s plan aims to strengthen the electricity sector through the implementation of Advanced Measurement Infrastructure, network automation, distributed resources, and electric vehicles. These initiatives present both technological and economic challenges, given the current conditions in various Colombian municipalities, many of which will struggle to meet them. In response to this need, it is proposed to evaluate a business model to encourage the development of projects that facilitate the modernization of the distribution network, by supporting the network operator as a strategic partner. The distribution network of the municipality of San José de Guaviare in Colombia is used as a case study. The results indicate that this approach is attractive for the public service provider and demonstrate that continuous improvement in service quality indicators can be achieved without significantly impacting the local population’s economy.

This study investigates how and the extent to which different forms of ownership (foreign, managerial, diluted, concentrated and institutional) influences carbon emission disclosure quality as shown in the levels of the voluntary carbon emission related disclosures in the stand-alone sustainability report of the listed oil and gas companies in Nigeria. Hence, we complement the three leading streams of research on the determinants of carbon emission disclosure quality. We analyzed the research objective using data from the 22 listed oil and gas companies in Nigeria since they are the dominant greenhouse gas emitters globally and show higher commitment to pursuing companies and industrial actions in communicating environmental related information with the external stakeholders, that may reflect attitudinal changes and product sensitive innovations to reducing emission of carbon, carbon management, and targets. Using an ordered logistic regression analysis, we found several important results. First, the findings revealed that firms with greater proportion of foreign ownership exhibit higher carbon emissions disclosure quality, which suggest that the type of ownership correspond with firm’s proactiveness and commitment to environmental practices in the selected companies. Second, institutional ownership in negatively correlated with carbon emission disclosure quality, providing an implication that when institutions invest heavily in a company, they favor weak carbon related disclosure because it enables them to exploit minority shareholders. Third, we observed a negative correlation between ownership concentration and carbon emission disclosure, which indicates that controlling shareholders in form of institutional ownership may be prone to monopolizing carbon emission information to maintain superiority in monitoring and decision-making process.

Published: December 2024

Addressing the current environmental challenges requires optimizing climate actions and understanding the complex relationships among them. This paper aims to provide insights into how public investment in renewable energy influences various dimensions of climate change, including emissions, efficiency, renewable energy deployment, and policy effectiveness. This study seeks to explore the causal connection between public investment in renewable energy and the Climate Change Performance Indicator (CPI) from 2007 to 2017, utilizing data provided by German Watch. The method used is Dumitrescu and Hurlin’s (2012) Granger Causality. The study unveils a unidirectional causality from Renewable Energy Investment (REI) to climate change performance. Additionally, it emphasizes the critical role of energy efficiency in attracting investments in renewable energy. Surprisingly, the study finds that REI influences the quality of climate policy. Furthermore, the study identifies a bi-directional causality between a renewable energy share and REI. The contribution of the paper lies in its analysis of public investment in renewable energy, covering areas beyond just public finance for R&D in renewable energy, as also exploring the causal link between this investment and CPI. It offers policymakers insights on how financial governmental interventions can effectively drive climate action.

Published: December 2024

Human activities such as burning fossil fuels, deforestation, and economic growth are increasingly affecting the climate and temperature of the earth. Large amounts of greenhouse gases in the atmosphere have increased the greenhouse effect and global warming. By 2020, the concentration of greenhouse gases in the atmosphere has increased to 48% above its pre-industrial level. The main objectives of this study are to determine the level and the pattern of the relationship between dependent and independent variables. Also, this study examines the long-term and short-term impacts of energy consumption, economic growth, and non-renewable energy on carbon dioxide (CO2) emissions in Malaysia. Due to increased industrialization, Malaysia faces significant problems, such as environmental pollution. This study uses annual time series data from 1986 to 2021 and is analyzed using the Autoregressive Distributed Lag approach. The study suggests that energy consumption, economic growth, and non-renewable energy positively impact carbon dioxide (CO2) emissions. The results through dynamic ARDL indicate that energy consumption, economic growth, and non-renewable energy positively impact Malaysia’s carbon dioxide (CO2) emissions in the short-run and long run. The error correction model (ECM) provides short- run shocks in these variables and establishes equilibrium relations in the long run. Therefore, policymakers should consider implementing a carbon tax to be enforced on polluters to prevent ecological pollution at a minimum for the short-term regulation of carbon dioxide (CO2) emissions.

Published: December 2024

Studies related to the influence of climate risk on financial stability have been conducted, but rarely explore the gap of how climate change, both from the transition risk, physical risk, and opportunities derived from the efficiency of resources and energy sources needed for the company. Climate-related risks have not been empirically explored or discussed to date. Institutional theory is employed to determine what factors affect the financial stability gap regarding climate-related risks. The test was conducted quantitatively with 548 samples, where the data was collected from the data of companies listed on the Indonesia Stock Exchange. The results exhibited that climate-related risk harms financial stability, while size is able to mediate the relationship between climate-related risk and financial stability. The results display increased adaptation costs or losses due to climate change, such as costs incurred to mitigate climate-related transition risks in technology, reputation, markets, and policies and regulations. The practical implication of these results is that companies must implement proactive measures to manage climate-related risks. Companies, particularly those in sectors vulnerable to climate change, such as mining, agriculture, or manufacturing, must administer resources to mitigate the negative impacts of climate risks. Meanwhile, small companies can consider cooperation and collaboration to improve their operations, which may strengthen their financial stability in facing risks.

Published: December 2024

This study explores the influence of energy transformation on economic productivity and environmental sustainability in the Toba-Asahan region. The focus is on how renewable energy impacts community productivity, addressing a critical research gap in the literature. While energy transitions have been widely studied in other regions, specific research on their effects in Toba-Asahan remains limited. This study uniquely explores how human resources mediate the impact of renewable energy on community productivity in Toba-Asahan, shifting focus from environmental effects to economic productivity in a region previously under-researched in energy transformation studies. Using Structural Equation Modeling (SEM) based on data collected from 230 respondents, this research analyses the relationship between human resources, energy utilization, and productivity. The findings reveal that human resources have a significant positive impact on both energy utilization and productivity. However, the direct effect of energy on productivity is found to be statistically insignificant.

Many studies and scholars focus on the impact of climate change and pollution on economic green growth, linked to cultural variables. The discussed socio-cultural factors are measured by World Values Surveys, and environmental deterioration presented as different types of pollution are both independently essential for economic sustainability. The article refers to the socio-cultural index and sustainability. Environmental deterioration index as calculated by principal component analysis; Socio-cultural index formed by culture dimensions most of them mentioned by Hofstede (1980) such as masculinity, individualism and power distance; also, social development, and life expectancy and education level. Based on Environmental Kuznets Curve, there is a strong linkage among environmental degradation and income level. This paper applies Panel data by using generalized least square estimation; due to the existence of heteroskedasticity and serial correlation validate by Durbin-Watson test and Breusch-Pagan test respectively. The data was taken from World Value Surveys and European Value Surveys for Hofstede dimensions; World Bank such as GDP per capita, FDI, life expectancy at birth, tertiary school enrollment, and land pollution; and BP statistics of world energy for CO2 over years 2000–2022. The results show negative causal relationship between socio-cultural and economic sustainability and, a positive impact of environmental deterioration on economic.

The finding presents a strong positive and significant relationship between GT and IEP. The study also shows important and prominent implications from theoretical and practical perspectives.
Can Renewable Energy, Carbon Taxes, and Economic Growth Mitigate Countries’ Carbon Emissions?
Authors: Widianingsih Luky Patricia
Published: December 2024

The objective of this study is to provide empirical evidence on the effect of different types of renewable energy use (wind, solar, and hydro), the existence of carbon taxes, and economic growth conditions on carbon emissions of countries. The sample of this research is countries in the world in the 11-year observation period from 2010 to 2020 for 47 countries. The analysis method uses the panel data method stage. The results show that renewable energy, especially wind and solar, significantly affects a country’s carbon emissions in terms of electricity generation and installed capacity. While the installed capacity of hydropower affects emissions, its generation does not. The presence of a carbon tax and a country’s GDP have no effect on the level of carbon emissions. These findings emphasize the paramount importance of renewable energy in mitigating carbon emissions.

This study examines the short-and long-run effects of expenditure, tourists, the tourism sector, and AVTUR on the carbon emissions in Indonesia. The quarterly data are used to estimate the autoregressive distributed lag model in the study. The results show that in the short-run expenditure, tourists and AVTUR have positive and significant effects, while the tourism sector has adverse and significant effects on carbon emissions. Furthermore, in the long run, only AVTUR has positive and significant effects on carbon emissions, and other variables have adverse and significant effects. Policymakers should encourage friendly tourism to protect environmental quality and achieve optimal economic contributions.
China’s Energy Trade with the Middle East: Clean Energy versus Fossil Energy
Authors: Cevik Veli Ahmet
Published: December 2024

In the 21st century, China, with its substantial production capacity, has established itself as the “world’s factory,” becoming the world’s second-largest economy and leading exporter. It also needs a large amount of energy to continue its significant production and supplies almost half of the oil it uses from the Middle East. With its rising influence in economy, technology and military, China’s race with the United States has turned into a geopolitical rivalry. The US and the Western world have been imposing trade tariffs to China in several industries in order to limit its development in new technologies and military fields. On the other hand, in a period when the US’s global leadership has been questioned in recent years and discussions on a multipolar world order have been on the rise, China wants to fill the gap of the US in order to advance its global influence. In such a geopolitical and trade climate, China is developing its relations with the Middle East both to secure its energy resources and as new markets where it can sell new technology products such as electric vehicles and solar energy materials. This study examines China’s dependence on Middle Eastern energy resources and, in return, its investments in clean energy products.

This study investigates the impact of renewable energy consumption (REC), information and communication technology (ICT), and gross domestic product (GDP) on CO2 emissions in Saudi Arabia over the period 1990-2020. Utilizing an ARDL (Autoregressive Distributed Lag) model, the results reveal that GDP exerts a positive and significant effect on emissions in both the short and long term, suggesting that economic growth is associated with higher emissions. In contrast, REC has a negative impact, indicating that increased renewable energy consumption contributes to reducing emissions over time. However, the negative effect of REC on emissions in the short term suggests that transitioning to renewable energy may involve initial costs or disruptions that temporarily affect emissions. ICT also shows a negative influence on emissions in the long term, but its short-term effects are less consistent, reflecting the potential environmental costs associated with rapid technological expansion, such as increased energy consumption and electronic waste. The interaction terms between GDP and REC, as well as GDP and ICT, reveal that higher levels of renewable energy and technological development moderate the positive relationship between GDP and emissions, highlighting the complex trade-offs between economic growth, energy transition, and technological advancement. The findings emphasize the importance of expanding renewable energy infrastructure and fostering sustainable technological innovation to mitigate emissions while sustaining economic growth in Saudi Arabia.
China’s Sustainable Development under Climate, Energy and Policy Uncertainty: A Focus on SDG 7 and SDG 13

Published: December 2024

This paper contributes to the literature through a focus on the case of China and an investigation into the effects that CPU, EPU, and EUI variables have upon SDG 13 and SDG 7 through using ARDL and NARDL models along with the Dynamic Multipliers Effect Test. The analysis period includes annual data from 2003 to 2022. In the case of this study, from the literature review, some readily available studies measured the impact of China’s CPU, EPU, and EUI on the SDGs. It has also been observed that the degree of investigation on the effects of CPU on SDG 13 and SDG 7 has been shallow. Based on the results, the constructed SDG 7 and SDG 13 ARDL and NARDL models strongly validate the cointegration relationships among the taken variables. The test of symmetric effects on CPU in SDG13 from the results of the NARDL shows that the coefficients for LCPUpoz andLCPUneg are positive, which means the effects of positive shocks are more dominant. Additionally, to ensure model robustness, three parametric methods—Fully Modified Ordinary Least Squares (FMOLS), Dynamic Ordinary Least Squares (DOLS), and Canonical Cointegration Regression (CCR) are utilized. According to results, CPU, EPU and EUI have a substantial impact on the SDG7 and SDG13 indices.
