Examples of Origen’s use of the Holy Scriptures to Instruct the Christian Community in the Homilies on Jeremiah
Authors: Кожухов С.
Published: March 2023

В данном исследовании на нескольких примерах рассматривается метод и экзегеза Оригена для назидания христианской общины. Как известно, Св. Писание в доникейский период было практически единственным и важнейшим текстом для обоснования разных аспектов христианской жизни, в том числе и духовно-нравственного. Хороший экзегет — это хороший наставник и добрый пастырь. Ориген часто противопоставляет своё толкование иудейскому и маркионову, что было весьма актуально в III в. Всю ветхозаветную историю Израиля, Закон, пророков он рассматривает в контексте Нового Завета как прообразы или аналогии будущего. Ориген учит христиан под буквой видеть духовный смысл, что необходимо для понимания Св. Писания.

This study uses several examples to examine Origen’s method and exegesis for the edification of the Christian community. As St. John the Baptist is known. The Holy Scripture in the pre-Nicene period was almost the only and most important text for the justification of various aspects of Christian life, including spiritual and moral. A good exegete is a good mentor and a good shepherd. Origen often contrasts his interpretation with the Jewish and Marcion’s, which was very relevant in the third century. He considers the entire Old Testament history of Israel, the law, and the prophets in the context of the New Testament as a prototypes or analogies of the future. Origen teaches Christians to see the spiritual meaning under the letter, which is necessary for understanding the Holy Scriptures.

The inner feat of St. Sergius in the context of Russian history
Authors: Павлюченков Н.Н.
Published: March 2023

В русской истории преп. Сергий известен одновременно и как выдающийся духовный подвижник, и как тот, кого можно назвать «политическим деятелем», прилагавшим усилия по объединению Руси путем примирения враждующих между собой удельных князей. В статье обращается основное внимание на поступок преп. Сергия — отказ от митрополичьей кафедры в Русской Церкви перед лицом надвигающейся церковной и политической смуты, которую положительным решением можно было бы с успехом предотвратить. Отмечается, что, несмотря на предпринимаемые им самим усилия по сохранению духовного и политического единства русской земли, в ситуации необходимости выбора между церковно-государственным и аскетическим служением, преп. Сергий предпочел продолжать внутреннее подвижничество. И этот его выбор, в конечном итоге, не привел ни к расколу в Русской Церкви, ни к новым политическим потрясениям, так что преп. Сергий остался в истории Русской Церкви и Российского государства, в числе прочего, как пример действенности верно расставленных приоритетов. Из осуществляемого внутреннего подвига духовной жизни и единения человека с Богом следует благотворное влияние на всю внешнюю окружающую действительность, включая проблемы земного устроения Церкви и государства.

In Russian history St. Sergius is known both as an outstanding spiritual ascetic and as someone who can be called a «political figure» who made efforts to unite Russia. The article focuses on the act of the St. Sergius — the rejection of the Metropolitan cathedra in the Russian Church in the face of impending church and political turmoil. It is noted that, despite the efforts he himself is making to preserve the spiritual and political unity of the Russian land, in the situation of the need to choose between church-state and ascetic ministry, St. Sergius preferred to continue his inner asceticism. And this choice of his, in the end, did not lead to a split in the Russian Church, nor to new political upheavals. St. Sergius remained in the history of the Russian Church and the Russian state, among other things, as an example of the effectiveness of correctly set priorities. From the inner feat of spiritual life and the unity of man with God, a beneficial effect on the entire external surrounding reality, including the problems of the earthly organization of the Church and the state, follows.

Published: March 2023

Цель настоящего исследования — показать, как последовательное применение комплекса миссионерских средств привело к ослаблению влияния татар-магометан на чувашей-язычников и отступников от православной веры. В ходе исследования использовались следующие методы: сравнительно-исторический, причинно-следственный анализ связей между историческими событиями, типологизация исторических явлений, историко-системный анализ, структурно-диахронный анализ исторических процессов и абстрагирование в историческом познании. В итоге данной работы была воссоздана история миссионерского просвещения чувашского народа на примере селений Средние и Новые Алгаши Симбирской епархии за 25-летний период (1877–1902). Изучение опыта организации миссионерского просвещения нерусского населения может оказать помощь миссионерам для практического использования в современных условиях. Авторы статьи полагают, что изложенные в данной статье исторические сведения могут быть отражены в учебных пособиях по истории Симбирской епархии.

The purpose of this study is to show how the consistent use of a complex of missionary means has led to the weakening of the influence of Tatar Magomethanes on the Chuvashi-pagan and apostates from the orthodox faith. In the course of the study, the following methods were used: a comparative historical, a causal analysis of the connections between historical events, the typologization of historical phenomena, historical and system analysis, structural- diachronous analysis of historical processes and abstraction in historical knowledge. The overall result of the study was the reconstruction of the history of the organization of missionary education of the Chuvash population on the example of the villages of Sredniye and novye Algashi of the Simbirsk diocese over a 25-year period (1877–1902). Studying the experience of the organization of missionary education of the non-Russian population can help missionaries for practical use in modern conditions. The author of the article believes that using historical information presented in this article is also possible in generalizing studies in textbooks on the history of the Simbirsk diocese. The authors of the article believe that historical information set forth in this article can be reflected in the textbooks on the history of the Simbirsk diocese.
Using perceptual classes to dream policies in open-ended learning robotics
Authors: Romero Alejandro , Meden Blaz , Bellas Francisco , Duro Richard J.
Published: March 2023

Achieving Lifelong Open-ended Learning Autonomy (LOLA) is a key challenge in the field of robotics to advance to a new level of intelligent response. Robots should be capable of discovering goals and learn skills in specific domains that permit achieving the general objectives the designer establishes for them. In addition, robots should reuse previously learnt knowledge in different domains to facilitate learning and adaptation in new ones. To this end, cognitive architectures have arisen which encompass different components to support LOLA. A key feature of these architectures is to implement a proper balance between deliberative and reactive processes that allows for efficient real time operation and knowledge acquisition, but this is still an open issue. First, objectives must be defined in a domain-independent representation that allows for the autonomous determination of domain-dependent goals. Second, as no explicit reward function is available, a method to determine expected utility must also be developed. Finally, policy learning may happen in an internal deliberative scale (dreaming), so it is necessary to provide an efficient way to infer relevant and reliable data for dreaming to be meaningful. The first two aspects have already been addressed in the realm of the e-MDB cognitive architecture. For the third one, this work proposes Perceptual Classes (P-nodes) as a metacognitive structure that permits generating relevant “dreamt” data points that allow creating “imagined” trajectories for deliberative policy learning in a very efficient way. The proposed structure has been tested by means of an experiment with a real robot in LOLA settings, where it has been shown how policy dreaming is possible in such a challenging realm.
When is there enough data to create a global statistic?
Authors: Mahler Daniel Gerszon , Serajuddin Umar , Maeda Hiroko
Published: March 2023

To monitor progress towards global goals such as the Sustainable Development Goals, global statistics are needed. Yet cross-country datasets are rarely truly global, creating a trade-off for producers of global statistics: the lower the data coverage threshold for disseminating global statistics, the more can be made available, but the lower accuracy they will have. We quantify this availability-accuracy trade-off by running more than 10 million simulations on the World Development Indicators. We show that if the fraction of the world’s population on which one lacks data is x, then one should expect to be 0.37 *x standard deviations off the true global value, and risk being as much as x standard deviations off. We show the robustness of this result to various assumptions and give recommendations on when there is enough data to create global statistics. Though the decision will be context specific, in a baseline scenario we suggest not to create global statistics when there is data for less than half of the world’s population.
The effect of color vision resolution on intra-oral shade-selection accuracy
Authors: Liu Xin , Guo Xinwei , Zhang Zhimin , Wu Huang , Zhang Yu , Zhao Hongyan
Published: March 2023

BACKGROUND: Dentists must be able to identify subtle color changes as shade-matching is crucial in aesthetic dentistry. OBJECTIVE: To determine whether color discrimination ability is related to shade-matching accuracy among dentists. METHODS: The sensitivity of the normal-color vision population to different colors was investigated using Farnsworth Munsell 100 Hue (FM-100) test results. The FM-100 test was administered to 37 dentists at the Hospital of Stomatology, Jilin University. Sensitivity of dentists with normal-color vision to different colors was investigated using the FM-100 test. Participants were instructed to arrange color caps of various colors according to the gradual change in colors and the results were scored. Visual shade matching test using Vita 3D-MASTER shade guide was performed to determine shade-matching accuracy. The relationship between color discrimination ability and shade-matching accuracy was analyzed. The number of misplaced color caps in the FM-100 test was also calculated. RESULTS: The FM-100 test revealed that 16 and 21 participants had excellent and average color discrimination ability, respectively, and their shade-matching accuracies were 68.75% and 66.67%, respectively. No significant difference was observed in the shade-matching accuracy between the two groups. No significant correlation was observed between the color discrimination ability and shade-matching accuracy. In addition, the number of wrong color caps on the 43–63 color tray with the transition from blue-green to blue-purple was the highest according to Friedman’s test. CONCLUSION: Color discrimination ability of dentists does not affect their visual shade-matching accuracy. Additionally, people with normal color vision are not sensitive to the transition from blue-green to blue-purple.

Published: March 2023

BACKGROUND: The incidence of anxiety in patients with breast cancer is high, which seriously affects the physical and mental health of patients. OBJECTIVE: This study aimed to investigate the effect of acupoint stimulation on the anxiety of patients with breast cancer during operations and in the waiting period for intraoperative frozen section analysis. METHODS: Sixty patients with breast cancer experiencing anxiety who met the inclusion and exclusion criteria were randomly divided into the experimental group and the control group. The patients in the control group received routine nursing, and the patients in the experimental group were given acupoint stimulation on the basis of routine nursing. The HAMD scores, blood pressure readings, and heart rates were recorded before admission at one hour before the operation and in the waiting period for intraoperative frozen section analysis. RESULTS: The HAMD scores, blood pressure readings, and heart rates of the two groups showed an upward trend at all time points, and the differences were statistically significant. Compared with the control group, there were significant differences in indices detected at one hour before the operation and in the waiting period for intraoperative frozen section analysis. CONCLUSION: Acupoint stimulation therapy can effectively alleviate anxiety in patients with breast cancer.

Authors: Riemer Lena , Dargel Jens , Schäferhoff Peter , Eysel Peer , Steimel Thomas , Reineck Sönke , Grevenstein David
Published: March 2023

BACKGROUND: Rupture of the anterior cruciate ligament (ACL) is one of the most common knee injuries and has substantial impact on knee function. Beside primary ruptures, an increasing number of re-(re-)ruptures occur, representing a therapeutical challenge for the treating surgeon. Several risk factors for re-ruptures have been previously identified, including an increased tibial slope. OBJECTIVE: In this study, we investigated the effect of femoral condyle configuration on ACL-ruptures and re-ruptures. METHODS: In-vivo magnetic resonance imaging scans of three different groups of patients were compared. Group 1 included patients with an intact ACL on both sides, group 2 included patients with primary, unilateral ACL-rupture, while group 3 included patients with an ACL-re-rupture or re-(re-)rupture. Fourteen different variables were obtained and analyzed regarding their impact on ACL-re-(re-)rupture. RESULTS: Overall, 334 knees were investigated. Our data allowed us to define parameters to identify anatomical configurations of bones associated with an increased risk of ACL-re-rupture. Our results show, that patients with ACL-re-rupture show increased radii of the extension facet of the lateral femoral condyle (p< 0.001) as well as of the extension facet of the medial femoral condyle (p< 0.001). CONCLUSION: We conclude that a spherical femoral condyle form does influence the clinical outcome after ACL-reconstruction.

Published: March 2023

BACKGROUND: Few studies have compared the clinical efficacy of unilateral and bilateral pedicle screw fixation and fusion in treating atlantoaxial fracture-dislocation. OBJECTIVE: To compare the efficacy of unilateral and bilateral fixation and fusion for atlantoaxial fracture-dislocation and to explore the feasibility of the unilateral surgical procedure. METHODS: Twenty-eight consecutive patients with atlantoaxial fracture-dislocation were included in the study from June 2013 to May 2018. They were divided into a unilateral fixation group and a bilateral fixation group (14 patients in each group with an average age of 43.6 ± 16.3 years and 51.8 ± 15.4 years, respectively). The unilateral group had a unilateral anatomical variation of the pedicle or vertebral artery, or traumatic pedicle destruction. All patients underwent atlantoaxial unilateral or bilateral pedicle screw fixation and fusion. Intraoperative blood loss and operation time were recorded. The visual analog scale (VAS) and Japanese Orthopedic Association (JOA) scoring systems were used to evaluate pre- and postoperative occipital-neck pain and neurological function. X-ray and computerized tomography (CT) were used to assess atlantoaxial stability, the implants’ position, and bone graft fusion. RESULTS: All patients were followed up for 39–71 months postoperatively. Intraoperatively, no spinal cord or vertebral artery injury was observed. At the last follow-up, occipital-neck pain and neurological function in the two groups were significantly improved (P< 0.05). The X-ray films and CT showed satisfactory atlantoaxial stability, implant position, and osseous fusion in all the patients at 6 months postoperatively. CONCLUSION: Unilateral and bilateral pedicle screw fixation and fusion can restore atlantoaxial stability and improve occipital-neck pain and neurological function in patients with atlantoaxial fracture-dislocation. The unilateral surgical procedure can be a supplementary option for patients with unilateral abnormal atlantoaxial lesions.
Dual stage ensemble technique for intrusion detection in cloud computing
Authors: Neelakantan P. , Sudhakar Yadav N.
Published: March 2023

A capability of cloud-based IDS in identifying complicated and anonymous attacks is rising in the current era. However, unwanted delays hinder the detection rate. A malicious user might utilize vast quantities of computational power. The cloud provides to perform attacks both within and without the cloud. Furthermore, there are major challenges for intrusion detection due to the ease of the cloud and also the continual restructuring and movement of cloud resources. Intruder detection, feature extraction, and data processing are all included in the novel optimization-based Intrusion Detection System (IDS) paradigm that will be presented in this study. Data normalization is used to first pre-process the input data. Then, appropriate feature extraction is carried out, including the extraction of (a) raw features, (b) statistical features, then (c) higher-order statistical features using suggested kurtosis. The detection phase is then applied to the retrieved features. A two-stage ensemble method is suggested for finding intruders in clouds. Random forest (RF), Support Vector Machine (SVM), optimal Neural Network (NN), and RNN make up the suggested ensemble technique. The RF, SVM, and Optimized NN algorithms are directly fed the collected features. The output of these classifiers is then provided to the RNN classifier (i.e.), RF output to RNN1, SVM output to RNN2, and optimized NN output to RNN3. Then, the weighted average of RNN 1, 2, and 3 is considered as the final output. A Self Adaptive Salp Swarm Optimization optimizes the weights of NN for exact detection (SA-SSO). Finally, a test is conducted to confirm the developed model’s superiority.

Authors: Liudmyla Lukasheva
Published: March 2023

The purpose of the article is to conduct a culturological reflection of the creative phenomenon of M.M. Sinelnikov in the dimension of the game conception of J. Huizinga. The methodology of research is based on the use of a set of general scientific and specific scientific methods in accordance with the cultural discourse. The historical method is used to illuminate the problems to cover and analyze the constituent components of the investigated problems. The hermeneutic method was used to study and interpret the theoretical provisions of the studied problems. To conceptualize the main points and factors investigated the problems, used the method of generalization. The scientific novelty is to address the little-studied problems of the creative phenomenon of the prominent artistic figure-reformer of the late 19th – early 20th centuries M.M. Sinelnikov and his analytical dimension through the prism of the game conception of  J. Huizinga. Conclusions.  An appeal to the creative phenomenon of M.M. Sinelnikov through the prism of the playful conception of culture by J. Huizinga made it possible to carry out a more extensive and in-depth analytical dimension of the investigated problems. As a result of the research, the correspondence of M.M. Sinelnikov`s artistic essence to the concept of a Homo Ludens is established. The basic factors of  influence of the creative phenomenon of M.M. Sinelnikov on the process of transformation of the socio-cultural space  of Ukraine in the late 19th  –  early 20th centuries are determined.  Generalizing, we note that the analytical dimension of the creative phenomenon of M.M. Sinelnikov in the coordinates of the game conception of culture J. Huizinga significantly deepened the idea of the importance of artistic activity and its cultural activities in the formation of socio-cultural space of Ukraine in the late 19th – early 20th centuries. In addition, in our opinion, M.M. Sinelnikov`s unique artistic experience is worthy of a return to cultural circulation in order to integrate it into the realities of contemporary artistic progress.
MARGINALITY AS A REALITY AND A PERSPECTIVE OF TRANSITION: CONCEPTUAL APPROACHES IN CULTURE
Authors: Martynova Svitlana
Published: March 2023

The purpose of the article. The socio-philosophical analysis of the peculiarities of margins in the conditions of globalization, determinants, and mechanisms of social transit of marginal individuals and marginal communities in the integrated socio-cultural space is studied. The aim is to study marginality as a socio-cultural and existential phenomenon that has meta anthropological and creative potential to determine its role in the cultural space. Methodology. The article combines cultural and philosophical analysis with dialectical and synergetic methods in the study of marginal communities in culture as complex, open, dynamic, self-organized, holistic systems, the transformation of which is considered through the dialectical law of mutual transition of quantitative meanings and qualitative changes. Scientific novelty. Most modern researchers interpret the state of Ukrainian socio-culture as borderline close to critical. The proposed loss is a special mode of transition and is associated with the risk of avalanche-like development of total marginalization of society. Conclusions. It was found that "margin" means an objective social process that reflects the processes of distancing specific social objects from the dominant axiological guidelines in society the distribution of material goods and is characterized by a dichotomy of "ascending-descending"; "Marginal transition" appears as a change in the essence of social relations of a social object which fixes its specific position in society; "Marginal leap" is defined as a form of transition of the community to a new social order in a relatively short time. The theoretical and practical significance of the obtained results lies in identifying and substantiating the peculiarities of the transformation of marginalized communities in the context of globalization. Substantiation of the specifics of the socio-philosophical design of the transit of the Ukrainian community into the integrated socio-cultural space will contribute to 1) clarification of external and internal contexts of social transformation; 2) systematization of factors that determine the margins of the community, in order to determine the determinants of its demarginalization; 3) elaboration of integration guidelines, compromises for an inhomogeneous society. The current stage of development of society is accompanied by a qualitative and large-scale transformation of social ties, group dominants, socio-cultural stereotypes which determines the peculiarity of marginal transformations in the context of globalization. The high dynamics of transitive processes in society affects the objective formation of significant disparities in various spheres of social relations. As a result, the scale of the marginalization of society is increasing.

Published: March 2023

Regardless of the fact, whether governments of particular country implemented the strong lockdown measures to prevent the spread of COVID-19 or not, the economies of each country all over the word have been suffered considerably due to the shocks caused by the pandemic. We observed slowdown of economic activity, macroeconomic instability and shifts in consumption preferences supplemented by rising unemployment as well as significant fluctuation of demand and production capability. The research problem addressed in this paper focuses on dynamic properties of output and inflation fluctuations that occur in response to economic shocks different magnitudes and types. We use a system dynamic approach and constructs two system dynamic models to examine the dynamics of output, prices, wage and inflation. The paper indicates ranges of relevant parameters’ values that correspond with sensitivity of output to demand and production capability changes related to possibility of reaching new equilibrium point. To explore the variety of prices and wage behavior in response to shocks we evaluate distinguish possible phase diagrams associated with stable node, stable focus, circle, unstable focus and unstable node. The results is a contribution to discussion of the policy issues related to mitigation of recession caused by unpredictable and strong shocks.

Authors: Huseynli Nigar
Published: March 2023

The main purpose of this study is to investigate the causal relationship between world oil prices and gold prices. For this purpose, the study is divided into two groups and evaluated as pre-pandemic and post-pandemic. The data set required for the study is evaluated on a daily basis and includes the period from January 2011 to June 2022. For the data of the examined variables, the stationary test was carried out by using the Extended DickeyFuller (ADF) unit root test. In the case of level, it is concluded that the related series are not stationary for these variables. According to the ADF and Johansen cointegration results obtained by applying the first-order difference operation, it was determined that the first-order differences of the variables of interest were stationary, that is, there was no unit root. The Engle-Granger test was used to determine whether there is a long-term relationship between the two variables. The direction of the relationship was tried to be determined by using the Granger causality test. As a result of the study, it was concluded that there is a one-way causality relationship from gold prices to oil prices, before the pandemic.

Published: March 2023

This paper investigates the total and net directional connectedness of the energy market and currency market amid volatilities (local and international) of BRICS for the period May 7, 2012 to March 31, 2022. The Time-varying parameter Vector Autoregression (TVP-VAR) connectedness approach is specifically employed. We reveal that the average value of the total connectedness index (TCI) is 46.91%, for the specific network of energy commodities, currency rates, and volatilities. Also, from the averaged dynamic connectedness, the global energy commodity index demonstrated the most transmitter of shocks. Conversely, BRICS currency markets (except for Brazilian Rubble) and most implied energy volatilities and realised exchange rate volatilities were net receivers of shocks. Moreover, the total connectivity indices were seen to vary significantly during the study sample period with strong susceptibility to crisis periods, especially, the COVID-19 pandemic. We advocate that most volatilities were consistent net transmitters across time as indicated by the net directional connectedness. The findings imply that in a network of energy commodities, exchange rate, and volatilities, risk minimisation is elated to boost investors’ confidence across time.

Published: March 2023

The COVID-19 pandemic has caused turbulence in many areas of the global economy. It also contributed to an increase in volatility on the energy commodities market. This spilled over into the derivatives market, particularly the crude oil futures market. The aim of the article is to compare the costs and effectiveness of using options on WTI oil from before and after the pandemic. The analyzes took into account the value of option premiums and final results obtained by buyers of call options from March 1, 2018 to April 14, 2022. The results showed that buyers of call options during the pandemic, despite paying much higher option premiums, experienced significantly higher payouts and rates of return. They were the highest for options with the longest expiry periods of 21-30 days. Research also showed that during the pandemic, options with strike prices set at a level higher than the price of oil on the contract date had particularly high rates of return, while the highest payout values were achieved by buyers of call options with low strike prices.

Published: March 2023

Unemployment rates is a social economic problem that needs further attention in most country in the world including Malaysia as it affects the citizen’s wellbeing. The studies on the macroeconomic determinants such as energy consumption for unemployment rates is hardly find in the previous studies. Higher energy consumption will usually lead to lower unemployment rates because people need to find a job and pay their bills. In these papers, we aim to investigates more macroeconomic variables impacts such as foreign investment, domestic investment, trade liberalization, inflation, urbanization, economic growth, corruption, besides energy consumption on level of unemployment rates for Malaysia. The paper utilized ARDL estimation based on annul data starting from 1984 until 2020. The outcomes revelas a mix expected sign between the independent variable and the dependent variables for the long run.

The importance of energy has made it the focus of many studies, discussions and policies. The studies carried out provide important ideas about the extent and in which direction the energy policies to be implemented affect the economic activities, and as a result, what kind of path should be followed. In terms of policy makers, determining the direction of causality is extremely important for the curriculum of the projects. In this study, the relationship between energy consumption, carbon emissions and economic growth in ASEAN-5 countries between the years 1990-2021 was examined. As a result of the causality analysis, it was found that there is a bilateral causality relationship between economic growth and CO2 emissions in Singapore; it has been determined that there is a unilateral causality relationship from economic growth to CO2 emissions in the Philippines, and from CO2 emissions to economic growth in Indonesia and Malaysia. In addition, there is a bi-directional causality relationship between economic growth and energy consumption in Singapore; there is a unilateral causality relationship from economic growth to energy consumption in Indonesia and the Philippines.
Relationship between Energy Consumption, Foreign Direct Investment, and Labor Force Participation Using the VECM Model: Empirical Study in OECD Countries
Authors: Wahyudi Heru , Palupi Widia Anggi
Published: March 2023

The purpose of this study is to determine the causal relationship as well as the long-term and short-term relationship between total energy consumption, foreign direct investment (FDI), and labor force participation rates in OECD countries from 1994 to 2019 using Granger Causality Test and Vector Error Correction Model (VCEM). In this study, it is found that energy consumption and FDI have a two-way causality, energy consumption and the labor force participation rate have a two-way causality and FDI and the labor force participation rate have a two-way causality. In the long term, FDI has a significant positive effect on energy consumption while labor force participation has an insignificant negative effect on energy consumption. Meanwhile, in the short term, FDI and labor force participation rates have no effect. This research contributes to decision-making in the field of energy, FDI, and improving the quality and quantity of the workforce in OECD countries.

Oil is regarded as one of the most significant energy sources in the world due to the enormous impacts it has on the level of the economy as a whole in both developing and developed countries and for both producing and importing countries. so, this study aims to know the effects of fluctuations in oil prices on the Egyptian public budget during the period from 2000 to 2022. For this purpose, the study used the GLM(Generalized linear Model) model, which is one of the first studies to use this model in economics. The study concluded that oil price fluctuations negatively affect the public budget, which means that there is a positive relationship between oil price fluctuations and the general budget deficit in Egypt as a result of Egypt being one of its importing countries. Therefore, the rise in oil prices leads to an increase in the public budget deficit, and its low prices may contribute to a decrease in this deficit.
The Impact of Climate Change on International Tourism: Evidence from Egypt
Authors: Elsayed Mona Rabea Abd Elfattah
Published: March 2023

The tourism industry is one of the most important sectors that contributes to global growth. Climate change can have a significant impact on tourism since it requires appropriate weather conditions and a clean environment. Given the close relationship between climate change and tourism, the current study aims to investigate the impact of climate change on international tourism in Egypt from 1990 to 2020. This study aims to supplement the literature on tourism and environmental quality. The autoregressive distributed lag (ARDL) model used in this study to investigate both short and long-run estimates at the same time. Climate change was measured using changes in precipitation, carbon dioxide emissions, and temperature, with gross capital formation (% of GDP) and arable land (% of land area) serving as control variables. The results show that two climate variables (precipitation rate and temperature) have a positive impact but are not significant in the short and long run-on international tourism revenue. Furthermore, carbon dioxide emissions have a long-term negative impact on international tourism revenues.

The Greenmetric Program is one part of Telkom University's strategic planning in realizing a campus that cares and has an environmental culture by managing the environment in a systematic and sustainable manner. One of the programs is to reduce waste production. Therefore, it is necessary to conduct research related to optimizing waste management by implementing Onsite Waste Treatment Technology-Integrated-Independent-Environmentally Friendly (TOSS-TMRL). TOSS-TMRL Management System with Centralized Control Based on the Internet of Things (IoT) Towards a Smart ECO Campus to be completed on the spot. This will reduce pollution, operational costs, and waste management investment and can even function as Living Labs for environmental-based courses. In addition, optimization is also one of the efforts to realize a smart eco campus towards the best-ranking Green Metric Telkom University. Wireless communication technology is very efficient, effective, and easy to use. One of the applications can be applied to determine the condition of environmental cleanliness in a campus area by integrating microcontroller technology and detection devices (sensors, QR codes, AR/imaging, and CCTV) with Wireless Sensor Networks (WSN) and IoT applications as tools to increase awareness of the importance of sorting waste so that the cleanliness of the campus area can be maintained. In this study, a system and network architecture design were carried out based on the number of sensor nodes, the number of recycle bins, the number of garbage transportation equipment, the number of buildings, the number of areas, and the ability of Data Transfer Nodes (DTN) to provide information to the server taken from the recycle bin of each room/building, business areas, SME facilities, canteens, and dormitories or local areas. With this system, it is hoped that there will be no accumulation of garbage and allow users/garbage managers to interact with the system through a web browser and android application.
Financial Sector Troubles and Energy Markets
Authors: Gormus Alper , Soytas Ugur
Published: March 2023

Literature shows the dynamics of energy markets impacting a variety of sectors. In response to the 2007/2008 financial crisis, the U.S. Treasury provided financial assistance (bailouts) to hundreds of public and private financial institutions under the Troubled Asset Recovery Program (TARP) and the Targeted Investment Program. Several studies suggest that bailouts alter the risk profile of the receiving companies. Since risk profiles are at the core of volatility transmissions between asset groups, in this study, we evaluate the volatility impacts of energy markets on these financial institutions before and after they received financial assistance. After controlling for systematic components, our findings show no volatility transmission before the financial intervention but suggest robust volatility transmission from oil and natural gas markets to the bailout banks post bailouts.
