Published: November 2024

As redes sociais e a internet são uma realidade que permeia a vida contemporânea. O acesso facilitado à tecnologia reconfigura substancialmente como estabelecem suas conexões interpessoais, expressam suas opiniões enquanto exploram o universo virtual. O artigo investiga a comparação com os padrões idealizados de beleza e sucesso, pode acarretar problemas, como a deterioração da autoestima, o surgimento de quadros ansiosos e depressivos, distúrbios do sono e distorções da autoimagem. É notável a capacidade do Instagram em instigar sentimentos de inadequação e solidão entre os jovens, os quais veem excluídos das narrativas idealizadas na plataforma. Destacam-se os efeitos deletérios do cyberbullying e da pressão social que permeia o ambiente virtual, como consequências para a saúde mental dos jovens adolescentes. A relação entre o uso exacerbado do Instagram e os desafios enfrentados no sono, na concentração e na regulação emocional torna patente a contribuição para um círculo vicioso. O método neste estudo é qualitativo, utilizando a revisão de literatura que busca identificar por meio de descrições detalhadas e conceitos teóricos. A pesquisa interpreta o uso e a exposição e as intenções dos indivíduos investigados, quando expostos à plataforma, proporcionando uma representação do quadro da saúde mental por meio de comportamentos, como autoestima, comparação, distúrbios do sono e transtornos mentais dos jovens envolvidos. As estratégias preventivas que incluem a promoção da autoestima e o estabelecimento de limites saudáveis, visando atenuar os efeitos do impacto da exposição na saúde mental dos jovens adolescentes, com enfoque no Instagram, aprofundam a compreensão dos fatores psicológicos.

Triple oxygen isotope composition of CO2 in the upper troposphere and stratosphere

Published: November 2024

Abstract. High precision measurements of the triple oxygen isotope composition of CO2 (∆′17O) can be used to estimate biosphere-atmosphere exchange of CO2, the residence time of tropospheric CO2 and stratosphere-troposphere exchange. In this study, we report measurements of the ∆′17O(CO2) from air samples collected during two aircraft based programs, CARIBIC and StratoClim. CARIBIC (Civil Aircraft for the Regular Investigation of the atmosphere based on an Instrument Container) provided air samples from numerous transcontinental flights in the upper troposphere/lower stratosphere region. StratoClim (Stratospheric and upper tropospheric processes for better climate predictions) conducted intensive campaigns with the high altitude aircraft M55 Geophysica during the Asian Summer Monsoon Anticyclone (ASMA), providing air samples from altitudes up to 21 km. Using high precision ∆′17O measurements of the CARIBIC samples, we show that the N2O-∆′17O correlation, previously observed in the stratosphere, extends to the upper troposphere. Moreover, we found no significant spatial or hemispheric differences in ∆′17O(CO2) for the upper tropospheric samples collected during the CARIBIC program. However, in many of the StratoClim samples, with significant stratospheric contributions, we observed a much lower N2O-∆′17O slope compared to CARIBIC samples and previous publications. This deviation is attributed to change in eddy diffusion above the tropopause within the ASMA, confirming previously published model calculations. These samples provide the first experimental evidence that differences in vertical mixing/transport can lead to significantly different N2O-∆′17O slopes. High precision ∆′17O measurements can identify ejections of tropospheric air into the stratosphere based on the slope of the N2O-∆′17O correlation, as both tracers have chemical lifetimes longer than their transport times. Furthermore, we use the ∆′17O measurements from the lower stratosphere and the upper troposphere to estimate global stratospheric production and surface removal of the isotope tracer ∆′17O. The removal estimate is then used to derive an independent estimate of global vegetation exchange of CO2, confirming earlier estimates based on surface level ∆′17O measurements.

Published: November 2024

Abstract. Climate sensitivity and aerosol forcing are two of the most central, but uncertain, quantities in climate science that are crucial for assessing historical climate as well as future climate projections. Here, we use a Bayesian approach to estimate inferred climate sensitivity and aerosol forcing using observations of temperature and global ocean heat content as well as prior knowledge of effective radiative forcing (ERF) over the industrial period. Due to limited information on uncertainties related to the time evolution of aerosol forcing, we perform a range of sensitivity analyses with idealized aerosol time evolution. The estimates are sensitive to the aerosol forcing pathway, with the mean estimate of inferred effective climate sensitivity ranging from 2.0 to 2.4 K, present-day (2019 relative to 1750) aerosol ERF ranging from −0.7 to −1.1 W m−2, and anthropogenic ERF ranging from 2.6 to 3.1 W m−2. Using observations and forcing up to and including 2022, the inferred effective climate sensitivity is 2.2 K with a 1.6 to 3.0 K 90 % uncertainty range. Analysis with more freely evolving aerosol forcing between 1950 and 2014 shows that a strong negative aerosol forcing trend in the latter part of the 20th century is not consistent with observations. Although we test our estimation method with strongly idealized aerosol ERF pathways, our posteriori estimates of the climate sensitivity consistently end up in the weaker end of the range assessed in the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR6). As our method only includes climate feedbacks that have occurred over the historical period, it does not include the pattern effect, i.e., where climate feedbacks are dependent on the pattern of warming which will likely change into the future. Adding the best estimate of the pattern effect from IPCC AR6, our climate sensitivity estimate is almost identical to the IPCC AR6 best estimate and very likely range.

Abstract. Our understanding of how rapid Arctic warming and permafrost thaw affect global climate dynamics is restricted by limited spatio-temporal data coverage due to logistical challenges and the complex landscape of Arctic regions. It is therefore crucial to make best use of the available observations, including the integrated data analysis across disciplines and observational platforms. To alleviate the data compilation process for syntheses, cross-scale analyses, earth system models, and remote sensing applications, we introduce ARGO, a new meta-dataset comprised of greenhouse gas observations from various observational platforms across the Arctic and boreal biomes within the polar region of the northern hemisphere. ARGO provides a centralised repository for metadata on carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) measurements linked with an interactive online tool (https://www.bgc-jena.mpg.de/argo/). This tool offers prompt metadata visualisation for the research community. Here, we present the structure and features of ARGO, underscoring its role as a valuable resource for advancing Arctic climate research and guiding synthesis efforts in the face of rapid environmental change in northern regions. The ARGO meta-dataset is openly available for download at Zenodo (https://doi.org/10.5281/zenodo.13870390) (Vogt et al., 2024).
2021 Alaska earthquake: entropy approach to its precursors and aftershock regimes
Authors: Vogel Eugenio E. , Pastén Denisse , Saravia Gonzalo , Aguilera Michel , Posadas Antonio
Published: November 2024

Abstract. We have conducted an entropy analysis in Alaska, a seismic-rich region in a subduction zone that exhibits a nontrivial behavior: the subduction arc alters the seismic activity from the eastern zone to the western zone, demonstrating a decrease in activity along the subduction. We analyze this zone through the Tsallis entropy and the mutability (or dynamic entropy) for the first time. Considering 13 870 seismic events after appropriate filtering, we analyzed a data set for the selected Alaska zone between 2000 and 2023. We have found agreement between the results for the two entropies. We have followed the value of the q parameter of the Tsallis entropy (Sq) finding values between 1.70 and 1.85, in concordance with values found in other seismic regions of the planet. The values of Sq decrease slightly over time but show a broad increase before the major earthquakes. Just opposite to Tsallis entropy, mutability shows a tendency to decrease prior to the major earthquakes. We used the simpler mutability method to further analyze this zone upon dividing the region into four subzones. The results show how mutability can identify the seismic activity in each zone. This study shows how an entropy approach can shed light on understanding the seismicity in subduction zones.

У статті проаналізовано відповідність норм податкового законодавства Україні положенням директив Європейського Союзу (далі – ЄС) із питань акцизного оподаткування енергетичних продуктів. Автори стверджують, що базові положення Директиви Ради 2003/96/ЄC від 27 жовтня 2003 року про реструктуризацію рамок Співтовариства щодо оподаткування енергетичних продуктів та електроенергії частково враховані у законодавстві України. Проте, наближення положень національного законодавства до права ЄС потребує подальшого удосконалення правового регулювання акцизного оподаткування електричної енергії та пального в Україні. Авторами наголошено на необхідності розробки та впровадження терміну «енергетичні продукти»; включення до переліку підакцизної продукції окремих видів олії, вугілля, природного газу (не скрапленого), смоли та бітуми (бітумні суміші), мастильних матеріалів; диференціювання ставки акцизного податку на пальне залежно від напрямів використання (промисловість, населення, тощо); запровадження єдиних одиниць виміру ставок акцизного податку на енергетичні продукти (електроенергія ‒у євро за МВт/год, паливо пічне побутове ‒ у євро за 1 000 кг, природний газ ‒ у євро за ГДж вищої теплотворної здатності та ін.). Запропоновано змінення порядку оподаткування акцизним податком операцій з реалізації електричної енергії та встановлення режиму оподаткування окремих енергетичних продуктів за напрямом їх використання (звільнення від оподаткування енергетичних продуктів, що використовуються як сировина для виробництва іншої підакцизної продукції). Наголошено на необхідності запровадження в Україні понижувального коефіцієнта на рівні 0,5 до ставок акцизного податку на важкі дистиляти (газойлі), призначені для використання сільськогосподарськими виробниками. У статті акцентовано увагу на важливості використання прецедентної практики Суду ЄС в частині акцизного оподаткування енергетичних продуктів при наближенні українського законодавства до права ЄС. Авторами проаналізовано практику Суду ЄС щодо тлумачення положень Директиви Ради 2003/96/ЄC від 27 жовтня 2003 року про реструктуризацію рамок Співтовариства щодо оподаткування енергетичних продуктів та електроенергії. Здійснено аналіз зареєстрованих у Верховній Раді України законопроєктів щодо імплементації положень актів права ЄС щодо акцизного податку, запровадження системи контролю за обігом нафти, газового конденсату та розчинників.
Non-Mobilised Pathways to Socio-Political Participation by Marginalised Youth in Authoritarian Contexts
Authors:   , Mutongwizo Nyasha
Published: November 2024

This thesis explores the socio-political participation of marginalised youth in authoritarian Zimbabwe to advance the under-researched concept of social nonmovements. Drawing on interviews and virtual ethnographic research with Zimbabwean youth, it highlights barriers such as repression, structural marginalisation, and lack of state support, which creates crises in youth citizenship and livelihoods. Developing concepts of social nonmovements, hustling and waithood, it shows how youth participate in non-mobilised ways through survival-focused activities and informal networks. This thesis critiques the common focus on politically active youth in democracies, filling a research gap on marginalised youth in the global south and their everyday participation.

Published: November 2024

This thesis presents a systematic review on the predictive power of investor sentiment indices for stock returns. It summarizes methods used to construct these indices and finds that their predictive power varies depending on the construction approach and the sentiment information they capture. Some indices work well for long-term predictions, while others excel in short-term trends. Predictive power is also influenced by economic cycles, holidays, cultural differences, and special events, especially during sudden disasters. Stocks with specific characteristics are more affected by indices using proxy methods.

In the manufacture of wire with high operational and mechanical properties, the use of high total degrees of compression is irrational, since cold plastic deformation reduces the diameter of the wire, and with hot deformation the initial diameter of the wire has its limitations. Therefore, wire processing by thermomechanical method has a huge potential to reduce costs and improve product quality. The article develops a technology of thermomechanical processing of stainless wire, which consists in preliminary heat treatment to obtain an austenitic structure and traditional drawing followed by cryogenic cooling. As a result of such processing, an ultrafine-grained structure consisting of a mixture of austenite and α – martensite and high strength and plastic properties were obtained. When drawing using cryogenic cooling, a structure with an average grain size of 1 microns was obtained, and a microstructure of 2 microns was obtained at ambient temperature.

The results of research on the urgent problem of reducing the risks of occupational diseases and occupational injuries among operators of technological installations of the main workshops of oil refining industries are presented. For the reliability of the influence of dangerous and harmful factors existing in the workplace, a questionnaire method is proposed, the form of which was developed in the form of questions concerning the nature and content of work, as well as factors of the working environment. The survey respondents were the operators of technological installations of the isomerization shop with the CMC-1 LK-6U unit of «PetroKazakhstan Oil Products» LLP. It was found that the largest number of operators (up to 90%) indicated the risks associated with psychological stress, which correlates with studies on the increase in anxiety and stress conditions in workers due to increased visual information on the operator's monitors during the technological process, constant interaction between shift workers to promptly correct emerging deviations in installations and equipment to prevent accidents and other emergencies. Occupational safety specialists of enterprises need to pay attention to the hazard factors for which an employee cannot give a satisfactory answer, due to the lack of specific data. The results of the survey on the health effects of such factors as various types of radiation showed that 100% of respondents noted that there is no information on them. In this regard, at enterprises in the field of occupational safety and health of person nel, measures are needed to carry out measurements and studies to obtain these data. The results of the survey of operators of technological installations on the influence of dangerous and harmful factors of the working environment in which they carry out their work functions allow the Department of labor Protection to receive correct and reliable information and use it in the development of the Register of Hazards of each workplace to assess the level of risk to the health and safety of workers.
REFORMULASI PAJAK ORANG PRIBADI SEBAGAI PEMENUHAN IURAN JAMINAN KESEHATAN NASIONAL DALAM RANGKA MENINGKATKAN EFEKTIFITAS PEMUNGGUTAN PAJAK
Authors: Benita Santy , Ardiansyah Ardiansyah
Published: November 2024

Penunggakan iuran Jaminan Kesehatan Nasional (JKN) oleh peserta mandiri merupakan ancaman bagi kebersinambungan program JKN. Untuk itu perlu dicari alternatif metode pendanaan, supaya program JKN yang dikelola oleh Badan Penyelenggaraan Jaminan Sosial Kesehatan (BPJS Kesehatan) dapat berkesinambungan, karena demi kepentingan pembangunan bangsa Indonesia. Merujuk pada Pasal 1 Undang-Undang Nomor 40 Tahun 2004 tentang Sistem Jaminan Sosial Nasional yang mewajibkan setiap warga mendaftar sebagai peserta program JKN. Selama ini wajib pajak yang telah membayar pajak penghasilan, merasa tidak mendapatkan imbalan langsung dari negara, karena kewajiban membayar pajak di Indonesia memang tidak ada imbalan langsung. Seharusnya  pemerintah mulai memikirkan cara agar warga yang taat membayar pajak dapat merasakan imbalan langsung dari kewajiban membayar pajaknya, yaitu dengan membebaskan Wajib Pajak Orang Pribadi (WPOP) dari kewajiban membayar iuran BPJS Kesehatan. Penelitian ini membahas bagaimana reformulasi wajib pajak orang pribadi sebagai pemenuhan iuran JKN dalam rangka meningkatkan efektivitas pemungutan pajak. Penulis menggunakan metode penelitian hukum normatif dengan data sekunder berupa peraturan perundang-undangan dan metode Library Research yang bersifat eksploratif dan berfokus pada kaidah hukum pajak dan hukum JKN. Hasil penelitian menyimpulkan bahwa pengaturan pendanaan JKN  saat ini dalam menjamin keberlangsungan program BPJS Kesehatan, sebagai kewajiban negara menyelenggarakan jaminan sosial bidang kesehatan sesuai amanat Undang-Undang Dasar Negara Republik Indonesia 1945 Pasal 34 Ayat (2), dapat berasal dari pemungutan pajak, dapat mengacu pada pasal 23A. Reformulasi pajak orang pribadi sebagai pemenuhan iuran JKN dalam rangka meningkatkan efektivitas pemungutan pajak,  perlu dilakukan dengan menetapkan pembayaran pajak oleh WPOP sebagai pemenuhan memperoleh jaminan sosial bidang kesehatan.
Analytical Solution of Fractional Order Diffusion Equations Using Iterative Laplace Transform Method
Authors: Feng Yihu , Huang Jing
Published: November 2024

In this present article, by using the Iterative Laplace Transform Method (ILTM), the diffusion equation of fractional order is solved. The ILTM, which works as a combination of two methods, the iterative method and the other is the Laplace transform method, is applied to several diffusion equations to obtain analytical solutions. The proposed method gives the closed-form of series solutions in terms of the Mittag-Leffler function, which is a queen of functions in fractional calculus. The main aim of this work is to present a simple but reliable algorithm for the solution of diffusion equations of the multi-dimensional type, which clearly describes the materials of density dynamics in the diffusion process. The results obtained by using the ILTM approach indicate that this approach is attractive computationally and implemented easily. Due to its straightforward approach and comfortable way of solving problems, the ILTM can be utilized to solve nonlinear fractional problems in various applied and engineering sciences.

It highlighted how foreign investment, international standards, and technological innovations have reshaped corporate structures and management strategies. The methodology included both quantitative and qualitative analyses, focusing on sectors such as agriculture, pharmaceuticals, and IT, which attract foreign investment and engage in international economic activities. Data was gathered through surveys and financial reports to explore management transformations spurred by European integration and foreign managers' influence. Key findings showed that foreign managers and Georgian specialists educated abroad have been crucial in modernising management practices by introducing international best practices adapted to local conditions. Adopting European standards has significantly improved operational efficiency and competitiveness, especially in quality-sensitive industries. However, challenges remain, particularly for small and medium-sized enterprises (SMEs), which face financial constraints in investing in staff training and new technologies. Resistance to change among middle management and employees further complicates the transition to innovative management approaches. In particular, Georgian companies must focus on building robust internal leadership and management talent to reduce reliance on external expertise. This includes creating ongoing professional development programs, fostering a culture of innovation, and ensuring that knowledge transfer from foreign managers to local teams is effective. Additionally, developing strategies to overcome resistance to change will be critical. Expanding research across more industries and incorporating objective performance metrics will provide a broader understanding of global economic changes in Georgia management practices

The purpose of the study was to analyse the existing problems of using the budgets of the Kyrgyz Republic and Ukraine and to develop recommendations for improving the management of public funds in the two countries. A comparative analysis of public finance management in Ukraine and Kyrgyzstan for the period 2019-2023 was carried out based on official statistical data, government programmes, and other theoretical sources. As a result of the analysis, it was found that budget deficits are typical for both countries. This situation has been observed in two countries for 2019-2023, with the exception of the situation in Kyrgyzstan in 2023. The annual increase in public debt is typical for both countries. For Kyrgyzstan, over the period 2019-2023, by more than 75.1%, and for Ukraine – by more than 3 times. Also characteristic of the two countries is the annual decrease in the transparency of the use of budgetary funds with deterioration in indicators by 25 points for Ukraine and 2 points for Kyrgyzstan for the period 2019-2023. As a result of the analysis, the main measures to improve the current situations in the two countries were identified: attracting foreign capital and changing the structure of expenditures and revenues to reduce the budget deficit, and digitalisation of public budget management and increasing the level of digital literacy of management staff to increase transparency in the use of public finances. It is more difficult for Ukraine to achieve such an effect, given the state of war. Such measures should be implemented gradually step by step for their synergistic effect as a result

Published: November 2024

The biopharmaceutical industry constantly presses for fast and low-cost bioprocess monitoring strategies. However, a recent study has shown that the Joint Extended Kalman Filter (JEKF) is inefficient in this monitoring type under biomanufacturing conditions. This work investigates the Dual Extended Kalman Filter (DEKF), Joint Unscented Kalman Filter (JUKF), and Joint Cubature Kalman Filter (JCKF) under these challenging conditions. Our theoretical analysis also reveals inefficiencies in DEKF, while our empirical tests using a synthetic dataset indicate that JUKF and JCKF only perform well with specific initial conditions for the state error covariance matrix, although with unconventional Kalman gain behavior. These results suggest nonlinear Kalman estimators in biomanufacturing still merit further investigation.

Published: November 2024

The hybridization of ML techniques with heuristics approaches is promising for difficult problems. This paper aimed to explore this hybridization in an NP-Hard Problem with a proposed MLHBRKGA, a hybrid approach combining a Biased Random-Key Genetic Algorithm (BRKGA) with Q-learning and a Random Forest Regressor with Local Branching to solve the Knapsack Problem with Forfeits (KPF). The analysis shows that the approach is competitive with the existing literature.

Authors: Otero Gomez Daniel , Mateus Rafael
Published: November 2024

Sewerage infrastructure is among the most expensive modern investments requiring time-intensive manual inspections by qualified personnel. Our study addresses the need for automated solutions without relying on large amounts of labeled data. We propose a novel application of Self-Supervised Learning (SSL) for sewer inspection that offers a scalable and cost-effective solution for defect detection. We achieve competitive results with a model that is at least 5 times smaller than other approaches found in the literature and obtain competitive performance with 10% of the available data when training with a larger architecture. Our findings highlight the potential of SSL to revolutionize sewer maintenance in resource limited settings.
Fast-forward FARGO : Accelerating Protoplanetary Disk Simulations with Limited Data
Authors: Tardugno Poleo Valentina
Published: November 2024

Hydrodynamic simulations of planets embedded in accretion disks around young stars are an essential tool in the study of planet formation and evolution. However, these simulations are expensive, and any quantitative comparisons between planet-formation theory and the observations of planets will require the execution of at least thousands of simulations. We present a U-net emulator built to accelerate the simulation package FARGO. Our emulator, Freesbee, was pre-trained with disk surface densities from 940 short, low-resolution FARGO simulations and fine-tuned using only 10 to 30 longer and higher-resolution simulations. The emulator takes as input the disk density and embedded planet position from the first few timesteps of a brief simulation and outputs the final state 5,000 dynamical times (years at 1 a.u.) later. The emulated disk densities have median fractional errors (relative to high-resolution FARGO runs) ranging from 0.9 to 6 percent with a median value of 3 percent; they are over 106 times faster to compute.

Published: November 2024

This study examines the integration of artificial intelligence (AI) in education, focusing on motivating pre-service teachers to utilise AI technologies. The research assesses factors influencing their motivation for AI learning and personalisation in higher education. Over 14 weeks, 180 pre-service teachers participated in a qualitative case study with quantitative content analysis. Results indicate a positive attitude towards AI use among these future educators. The study concludes that AI-enhanced learning can significantly improve teacher-student interactions through personalised feedback, learning guidance and collaborative experiences across various platforms. Findings suggest AI has the potential to enhance personalised learning by tailoring content to individual student needs, preferences and learning styles. Educational policies should encourage a balanced approach to AI implementation, recognising its benefits whilst maintaining human interaction. Although AI may reduce face-to-face engagement, striking a balance where it supports rather than replaces human interaction can strengthen teacher-student relationships. By providing detailed insights into students’ progress and challenges, AI can help teachers offer more targeted support and encouragement.

Published: November 2024

Continuing the search for new antimicrobial agents with antibiofilm activity, bis-quaternary ammonium compounds based on natural (3,5-dibromo-4-hydroxyphenyl)acetic acid derivatives were synthesized. Antibacterial and antibiofilm activity of ammonium salts was evaluated in vitro against S. aureus, E. coli, and P. aeruginosa, including antibiotic-resistant strains. Bis-quaternary ammonium salts 1, 5, and 6 showed antibacterial activity with MIC values ranging from 25.0 to 200.0 μg/mL. Notably, these compounds demonstrated a high level of antibiofilm activity. Ammonium salts 1 and 6 reduced biofilm formation against S. aureus ATCC 25923, P. aeruginosa PA01, E. coli ATCC 25922, and antibiotic-resistant P. aeruginosa by 92 - 97% at a concentration of 100.0 μg/mL. In addition, compounds 1 and 6 inhibited the biofilm formation of antibiotic-resistant E. coli isolate by 60% and 63%, respectively.

Published: November 2024

The mechanism and regioselectivity of 1,3-dipolar reaction of 2-azido-N-(4-diazenylphenyl) acetamide and an alkyne have been studied in gas phase and in DMSO using the B3LYP-GD3 functional and 6-31G(d,p) basis set. The reaction followed a one-step mechanism with asynchronous TSs. The calculated global reactivity indices calculated revealed, among other things, the nucleophile character of the 2-azido-N-(4-diazenylphenyl)acetamide and the electrophile character of the alkyne (4-bromo-2-chloro-1-ethynylbenzene), in addition to an electron transfer from the 4-bromo-2-chloro-1-ethynylbenzene towards the 2-azido-N-(4-diazenylphenyl) acetamide. The calculated local reactivity indices predicted the formation of the 1,4-triazole, with the most nucleophilic nitrogen and the most electrophilic carbon favoring its formation. However, analysis of the activation energies and thermochemistry parameters showed that the 1,5 triazole is energetically favorable and more stable under thermodynamic control. Bond order analysis coupled with bond formation evolution and the solvent effect was further investigated to support and highlight the asynchronicity in bond formation and the regioselectivity of the reaction, respectively.
