Published: September 2024

Introduction: Adolescence is a transitional period leading to adulthood, representing a significant phase of life. This stage accounts for one-fifth of the world's population. The 21st century has brought about rapid technological advancements and shifts in mass media. In today’s high-tech world, it is nearly impossible to prevent children from engaging with smartphones. However, they are susceptible to the harmful effects of electronic gadgets. Therefore, it is crucial to guide them in using these gadgets wisely. This study focuses on the hazards of smartphones during this complex phase of development. Objectives: To evaluate the effectiveness of the SIM and improve awareness among adolescents on the hazards of using smartphones and techniques to overcome the problems. Methods: This study utilized a quantitative descriptive approach. The research was conducted using a one-group pretest-posttest quasi-experimental design. A non-probability convenience sample of 60 adolescent students from various schools in Bangalore was selected. Data was collected using a pre-tested semi-structured questionnaire administered both before and after the intervention. Results: Results of this study indicated a 51% increase in overall knowledge scores among adolescents in the posttest. The calculated 't' value was 28.4, which is statistically significant at the level of P < 0.001. The high and statistically significant mean difference suggests that the SIM was highly effective. Conclusions: Adolescents are particularly vulnerable to the effects of electronic gadgets on various aspects of their health. There is a clear need for health education, guidance, and counseling on the healthy use of these devices, which should be incorporated into the curriculum. As a result, they are more likely to use these gadgets wisely, with a focus on both physical and mental well-being.
Study of Waste Material for Concrete Brick Construction
Authors: Patil Harshal
Published: September 2024

The management of garbage is a critical issue in the modern world, particularly with regard to plastic and glass waste. Thousands of tonnes of plastic and glass are thrown in the trash every day, yet there aren't enough treatment and recycling options. Every day, a significant amount of plastic is thrown away or burned, contaminating the ecosystem and the atmosphere. Plastic trash build up in the environment poses a threat to both plant and animal life. Plastic is a material that is not biodegradable and takes thousands of years to disintegrate, polluting both land and water. Recycling plastic and glass garbage after their useful lives are through while generating economic value and causing the least amount of environmental harm is the secret to their sustainable management in a circular economy. Bricks are a common building material used to make masonry structures like walls and pavement. Numerous researches has been conducted on concrete that has been saturated with waste plastic and glass fibre, with positive outcomes and many benefits. Numerous testing have been carried out to manufacture eco bricks, including compression tests and water absorption tests

Persepsi Masyarakat Lueng Bata terhadap Kisah Para Nabi dalam Tafsir Al-Ma’thur
Authors: Fajri Zakiatun
Published: September 2024

The stories of the Prophets that developed within the Lueng Bata Subdistrict community are understood without relying on reliable sources, and sometimes are involved with mythical and superstitious tales. If this situation continues, there is a concern that it may affect the purity of the Islamic teachings conveyed by the Prophet Muhammad and his successors. After interpretating al-Ma’thur's Tafsir, it showed that some of the stories of the Prophets described by the community were not explained in al-Ma’thur's Tafsir, while others found the same stories in it, either explicitly (identical) or with slight differences.
Abstrak: Kisah para Nabi yang berkembang dalam masyarakat Kecamatan Lueng Bata sebagiannya tidak dipahami berdasarkan sumber-sumber yang muktabar, bahkan di dalamnya diselipi cerita mitos dan tahayul. Jika keadaan tersebut terus berlanjut, dikhawatirkan mempengaruhi kemurnian ajaran Islam yang telah disampaikan oleh Rasulullah Saw. dan para penerus dakwahnya. Adapun berdasarkan hasil telaah kitab tafsir, ditemukan bahwa sebagian kisah para Nabi yang dideskripsikan oleh masyarakat tidak termuat penjelasannya dalam kitab tafsir al-Ma’thur, sedangkan sebagian lainnya ditemukan kisah yang sama di dalamnya, baik hal tersebut diungkapkan secara eksplisit (sama persis), ataupun memiliki sisi persamaan walau tampaknya agak berbeda.

Downhole heterogeneous heat transfer characteristics and rock stress distributions induced by liquid nitrogen jet
Authors: Cai Chengzheng , Wang Bo , Feng Yinrong , Gao Yanan , Yang Yugui
Published: September 2024

Liquid nitrogen jet is expected to provide a new idea for the breaking of
deep dry hot rock due to its low temperature. In order to study the
characteristics of het?erogeneous temperature and stress fields during
liquid nitrogen jet impingement, the downhole flow and stress
characteristics induced by liquid nitrogen jet were studied by a
thermal-hydraulic-mechanical coupling model. The results showed that under
the same conditions, the potential core and the maximum velocity of liquid
nitrogen jet were higher than water jet. The liquid nitrogen jet had a
larger region of high turbulent kinetic energy, and the heat transfer
efficiency with the bottom rock was obviously higher than water jet.
Compared with the water jet, the liquid nitrogen jet formed a tensile stress
zone in the bottom rock. The research was expected to provide a theoretical
basis for the rock breaking mechanism of liquid nitrogen jet.

В вегетационный период 2018 г. исследованы состав и динамика зоопланктона Казанского залива Куйбышевского водохранилища. Выявлено 69 таксонов зоопланктона. За время наблюдений видовое богатство зоопланктона составило 9 ± 1 таксонов на станцию, численность – 221.9±32.1 тыс. экз./м3, биомасса – 1.6 ± 0.5 г/м3, среднее значение суточной продукции – 0.124 ± 0.034 г/м3 в сутки. В динамике количественных характеристик зоопланктона выявлены два пика – в июне и августе, что характерно для мезотрофных озер умеренных широт в соответствии PEG- моделью Зоммера. Двухфакторный ANOSIM-анализ, выполненный на основании сходства станций по вкладу видов в общую продукцию, показал влияние на структуру зоопланктонных сообществ таких факторов, как месяц отбора проб (R = 0.472) и удаленность от нижней границы устья залива (R = 0.279) при уровне статистической значимости p = 0.1%. Фактор расположения станций относительно берегов и русла не имел значимого влияния на состав зоопланктона (R = −0.028 при p = 94.1%). Загрязнение Казанского залива в 2018 г. соответствовало среднемноголетнему уров- ню, β-мезосапробной зоне, что характеризовало воды как умеренно загрязненные.

During the growing season of 2018, the composition and dynamics of zooplankton in the Kazan Bay of the Kuibyshev Reservoir were studied. In total, 69 zooplankton taxa were identifi the species richness of zooplankton was 9 ± 1 taxa per station, abundance, 221.9 ± 32.1 thous. ind./m3, biomass, 1.6 ± 0.5 g/m3, average daily production, 0.124 ± 0.034 g/m3 per day. Two peaks were observed in the dynamics of quantitative characteristics of zooplankton (in June and in August), which was typical for mesotrophic lakes of temperate latitudes in accordance with Sommer’s PEG model. Two-factor ANOSIM analysis, performed on the basis of the similarity of stations in terms of the contribution of species to total production, evidenced on the infl of the month of sampling (R = 0.472; p = 0.001) and distance from the lower boundary of bay mouth (R = 0.279; p = 0.001) on the structure of zooplankton communities. The factor of station location relative to the banks and riverbed did not have a signifi eff on the compo- sition of zooplankton (R = −0.028; p = 0.94). Pollution in the Kazan Bay in 2018 corresponded to the long- term average level in the β-mesosaprobic zone, which characterized the waters as moderately polluted.

Впервые изучен микроэлементный состав (содержание железа, цинка, меди, никеля, свинца и кадмия) нерки, выловленной в Авачинском и Камчатском заливах. Проведено сравнение полученных данных с опубликованными сведениями для сахалинской горбуши, нагуливавшейся в океане или в Японском море. Показано, что восточно-камчатская нерка отличается низкими концентрациями Ni и Pb, но на порядок большим содержанием Zn и Cu, чем горбуша, пришедшая из океана и прошедшая через Курило-Камчатскую геохимически импактную зону. Количество Zn и особенно Cu в икре в несколько раз превосходит содержание этих элементов в семенниках самцов нерки. Различия в содержании микроэлементов в лососях обсуждаются с позиций их биологии, экологии (характера мест нагула), условия которых заметно различаются и зависят от природныхи антропогенных факторов.

This paper is the first study of the trace element content (iron, zinc, copper, nickel, lead, and cadmium) of sockeye salmon caught in Eastern Kamchatka (Avacha and Kamchatka Bays). The results obtained were compared with published data for Sakhalin herds of pink salmon feeding in the open waters of the Pacific Ocean and in the Sea of Japan. The East Kamchatka herds of sockeye salmon are characterized by low concentrations of Ni and Pb, but the content of Zn and Cu are an order of magnitude comparing to pink salmon came here from the open ocean waters and migrating through the Kuril-Kamchatka geochemical impact zone. The content of Zn and especially Cu in the sockeye salmon eggs are several times higher than that in the male testes. Differences in the content of trace elements in salmons are discussed in regard to their biology and ecology, i.e., nature of feeding grounds, where conditions are markedly different and depend on natural and anthropogenic factors.

Приведены концентрации хлорорганических пестицидов (ДДТ, ГХЦГ) и полихлориро- ванных бифенилов (28, 52, 155, 101, 118, 143, 153, 138, 180, 207 конгенеры) в шести видах карпо- вых рыб оз. Ханка. Хлорорганические соединения обнаружены во всех исследованных образцах. Доминирующей группой поллютантов были изомеры ГХЦГ, составляющие в среднем 70% от всех обнаруженных пестицидов. Доля α-ГХЦГ варьировала от 8 до 95%. Среди ДДТ и его метаболитов наиболее определяемым были o,p’- и p,p’-ДДЕ (в среднем – 10–100 и 15–100% соответственно). ПХБ во всех рыбах были представлены в основном низкохлорированными конгенерами – 28 и 52. По обнаруженным изомерам можно предположить давнее загрязнение оз. Ханка. Сравнение с водоемами южного Китая и Хорватии показало значительно более высокие уровни аккумуляции ГХЦГ и более низкие – ДДТ и ПХБ. При сравнении данных с требованиями нормативных докумен- тов Россиии Китая не выявлено случаев превышения допустимых концентраций.

Present study provides data of organochlorine pesticides (DDT, HCH) and polychlorinated biphenyls (28, 52, 155, 101, 118, 143, 153, 138, 180, 207 congener) content in six carp fi from Lake Khanka. Organochlorine compounds are found in all studied samples. HCHs isomers were dominant, constituting on average 70% of all pesticides detected. α-HCH content varied from 8 to 95%. Among DDTs, o,p’- and p,p’-DDE were predominant (on average 10–100 and 15–100%, respectively). PCBs content in all fi samples was primarily presented by low-chlorinated 28 and 52 congeners. Detected isomers evidence on the long-term pollution of Lake Khanka by persistent organic pollutants. Compare to southern China and Croatia, fi from Lake Khanka showed signifi higher levels of accumu- lation of HCH and lower levels of DDT and PCB. When comparing the data with the requirements of regulatory documents in Russia and China, no cases of exceeding maximum permissible concentra- tions were identifi

Mudanças no estilo de vida e práticas integrativas ajudam no controle, mas a adesão ao tratamento é difícil, especialmente em contextos de desigualdade. A polifarmácia e baixa adesão exigem acompanhamento multidisciplinar. Conclusão: Conclui-se que hábitos saudáveis e práticas integrativas são essenciais para controlar a hipertensão e melhorar o bem-estar mental. A gestão do cuidado em idosos exige acompanhamento multidisciplinar para garantir a adesão ao tratamento e minimizar complicações.
Abolição e Racismo nas imagens de Angelo Agostini
Authors: Maringoni Gilberto
Published: September 2024

A campanha abolicionista (1870-1888) foi pautada por intensa disputa política nos principais centros urbanos do Brasil, com forte participação da imprensa. Mesmo tendo alcance limitado por seu caráter artesanal e pela elevada taxa de analfabetismo registrada no Censo de 1872, surgiram variadas publicações voltadas para a causa, que galvanizou a opinião pública e os próprios escravos. O presente trabalho volta-se para o papel da imprensa ilustrada e para seu mais destacado autor, o caricaturista ítalo-brasileiro Angelo Agostini (1843-1910). Passado o 13 de maio de 1888, o autor, além de outros abolicionistas,  revelam-se racistas e preconceituosos em relação aos negros. Para entender o aparente paradoxo, é preciso mergulhar no que foi o abolicionismo branco, nas causas objetivas da libertação, nas formulações sobre branqueamento e na situação do negro após a Abolição

Published: September 2024

In the last few decades, pragmatic competence has become one of the issues that captured academic attention in education settings. Yet, teachers’ perceptions of pragmatics and teaching pragmatics has yet to be closely investigated in the context of Moroccan higher education and therefore remains uncharted in literature. To address these gaps, the present study explored how Moroccan university professors view pragmatics and pragmatic teaching. It also explored how they use their pragmatic knowledge in the classroom. A total of 10 university professors (6 males and 4 females) from two public universities (Moulay Ismail and Sidi Mohammed Ben Abdellah) in Morocco participated in the current study. Quantitative data were collected by completing an anonymous questionnaire, while qualitative data were collected through semi-structured interviews. Participants expressed their perceptions and described experiences of the importance of teaching pragmatics, issues related to culture and identity in teaching English as a Foreign Language, and materials and tasks in teaching pragmatics. The findings yielded that linguistic knowledge is as essential as pragmatic knowledge. Thus, striking a balance between pragmatic and grammatical competence and teaching them simultaneously is crucial. Learners with advanced grammatical knowledge may fail to use the target language appropriately. As such, the results indicated that some teachers are unaware of the importance of introducing pragmatics to students in the early stages of learning English. Their skills are enough to be good at transmitting cultural knowledge and suitable language competence to students. Practical implications for future research and practice are also discussed.

The current digital era also demands that English lecturers develop digital-based teaching materials. This study aimed to explore the application of the Fuzzy Delphi Method in the design of reading digital modules for university students in Riau since it benefits to improve students’ reading abilities and comprehension. This study answered the research question about the expert evaluations and feedback on the developed e-module regarding appearance/layout interface/navigation, content, reading strategies, language module, and the relevance of the e-reading module. Ten experts chosen from academic higher education or university for their specialization in English teaching, educational technology, and module development were involved in evaluating and providing feedback, ideas, and agreement on the things required to create and implement the digital reading module. The study employed the Fuzzy Delphi Method to synthesize expert perspectives and prioritize these criteria, allowing for a complete framework for digital module development. The FDM was employed to reach an expert agreement on the module’s critical design elements. The findings demonstrate the effectiveness of FDM in improving module design through consensus building and uncertainty management, thus contributing to improving educational practices in the digital era. The research results can make it easy to access the module and independently learn the course in unlimited time with interactive content.

Authors: Lenggogeni Devia Putri , Malini Hema , Maisa Esthika Ariany , Mahathir Mahathir
Published: September 2024

Background: Managing dietary and fluid intake for hemodialysis patients is crucial, but it is also challenging. Non-compliance to diet and fluid intake restriction may increase a patient’s morbidity and mortality. Exploring the experiences of hemodialysis patients who successfully manage those regimens may provide new insight to develop more effective strategies.
Purpose: The study aimed to explore the experiences of hemodialysis patients who successfully manage the dietary and fluid intake restrictions. 
Methods: A descriptive qualitative study was applied. Semi–structured interviews were conducted with 15 hemodialysis patients purposively recruited from a hemodialysis unit of a public hospital in West Sumatera, Indonesia. Interviews were transcribed verbatim and thematically analyzed to describe the phenomenon of hemodialysis patients. The study was reported following the COREQ guidelines.
Results: Most   participants in this study are female, aged between  38 – 63 years and length of hemodialysis 4 months – 6 years. The finding of this study was that the essential themes that explained how hemodialysis patients adhere to fluid and dietary restrictions   are 1) strategies for restricting fluid and dietary intake, 2) motivation to restrict fluid and dietary intake, 3) fear of the effects of non-adherence to fluid and dietary restrictions and 4) social support.

Authors: Vilela Noemia Bessa , Castihlos Daniela Serra , Murphy Anthony , Oplotnik Žan Jan
Published: September 2024

Sustainable development is a foundational element in European Union (EU) policies, yet there remains a lack of coherence among member states regarding the perception and response to environmental challenges, resulting in regional inequalities. The “Fit for 55” initiative by the EU is an ambitious strategy aiming to reduce greenhouse gas emissions by 55% by 2030, as part of its broader goal of achieving climate neutrality by 2050. This study investigates the economic impact and intergovernmental dynamics of the “Fit for 55” plan, analyzing its potential to not only meet environmental targets but also to foster economic resilience and social equity across the EU. The purpose of this study is to assess the effectiveness of the “Fit for 55” initiative in harmonizing environmental goals with economic and social policies among diverse EU member states. The study reveals that while the initiative offers significant potential benefits, such as stimulating innovation and creating jobs in green industries, it also faces considerable challenges, including economic disparities among member states and the social impacts of rapid decarbonization. These findings highlight the need for integrated approaches that address both environmental sustainability and socio-economic equity.
Ethanol added to washing water delays yellowing in Spinacia oleracea L. cv. ‘Matador’
Authors: Koc Ali , Kasim Mehmet Ufuk , Kasim Rezzan
Published: September 2024

The primary quality concern for spinach and other green vegetables during post-harvest handling is preserving the green color, specifically by delaying the yellowing caused by chlorophyll loss. The current study, therefore, aimed to investigate the effect of ethanol added to washing water in low concentrations on yellowing, chlorophyll loss, and the storage quality of spinach. For this purpose, ethanol was added to tap water at 0 µL L–1 (control), 200 µL L–1, 400 µL L–1, and 800 µL L–1, and after pre-washing, the spinach leaves were dipped in these solutions at a temperature of 16–18°C for five minutes. The spinach was stored at 4 ±1°C and at 90–95% RH for 21 days after being drained, dried, and packed, and the quality parameters were recorded at seven-day intervals. As a result of this study, the decline in chlorophyll losses was obtained especially by the application of the 400 µL L–1 ethanol treatment after the first 14 days of storage, and this result was positively correlated with both the color values L*, a*, b*, hue, yellowness index (YI), total color difference (ΔE), and the chlorophyll SPAD (soil-plant analysis development) values. Consequently, adding 400 µL L–1 of ethanol to the washing water was the most effective in delaying yellowing and chlorophyll loss in spinach. However, this effect declined with increasing solution concentrations and was accompanied by weight loss.
Takecallis nigroantennatus Wieczorek (Hemiptera: Aphididae) – implications of the ability to holocycle and overwintering of eggs on the spread of a potentially invasive bamboo aphid species
Authors: Borowiak-Sobkowiak Beata , Raut Aleksandra , Durak Roma , Wieczorek Karina
Published: September 2024

The bamboo-feeding aphid genus Takecallis (Hemiptera: Aphididae) contains eight taxa of Oriental origin. Four of them are introduced to Europe, where they are treated as a pest on Bambusoideae, showing invasive behavior with regard to range expansion, host plant spectrum and the ability to engage in an anholocyclic (without sexual phase) mode of reproduction. In contrast, the current field study confirms that the newly described species, the hardy bamboo aphid Takecallis nigroantennatus, reproduces holocyclically in temperate climatic conditions. The previously unknown morphs, i.e. the oviparous females and winged males, are described and illustrated in light and scanning electron microscopy. Chlorophyll fluorescence measurements were employed to evaluate the effects of insect feeding on the photosynthetic performance and general health of the host plant. The implications of the ability to holocycle and the overwintering of eggs on the spread of a potentially invasive aphid species are discussed.

The practice of organic agriculture (OA) in Nigeria has undergone expansion due, among other things, to consumer interest in food safety issues. Organic Farming (OF) is a holistic production management system that promotes and enhances agro‑ecosystem health, including biodiversity, biological cycles, and soil biological activity. The study investigated adoption drivers for organic vegetable farming practices among vegetable farmers in Oyo State, Nigeria. A total of 120 organic vegetable farmers were sampled through a multistage sampling procedure, and survey questions were administered. Data were analysed using frequency counts, mean, and Ordinary Least Square (OLS). The majority of farmers had a good knowledge of Organic Vegetable Farming Practices (OVFP), which aids adoption and is a good signal for economic returns and sustainable livelihoods. The most rated of the three benefit domains was health, which averagely was rated high (x̅ = 1.38), while economic (x̅ = 1.04) and environmental conservation benefits (x̅ = 1.00) were both rated average; with enhanced good health and long life; reduced climate change effects, as well as generation of greenhouse gases and higher premiums in the marketplace identified as top health, environmental conservation, and economic benefits, respectively. Although the majority of farmers highly adopted OVFP, however, a closer examination of the few practices that the majority of the farmers did not adopt was of health and environmental significance. Farmers’ age, education, farm size, household size, knowledge, health, and economic benefits of OF were important drivers of adoption and practices of OF among Oyo State, Nigeria vegetable farmers. OF, therefore, is a sustainable agricultural approach that holds great potential for effectively contributing to local food security, the health of citizens, increased family health, and environmental standards.
Machine politics: The cultural science of permissionless systems
Authors: Rennie Ellie
Published: September 2024

The survival of permissionless blockchains is typically cast as a cryptoeconomic security problem for mechanism designers to resolve. This essay argues that, long-term, these networks may require something that looks more like a UNESCO protection convention for machine culture than an equation. Ethereum’s machine culture is observable through the formation of a “’we’-group” (Hartley & Potts, 2014, p. 76), which is necessary for the establishment of common knowledge. While entry to the group is permissionless, maintaining membership boundaries demands active contributions from validator nodes. The paper discusses concerns that Ethereum’s consensus may be used for purposes beyond itself, making Ethereum vulnerable to external, non-machine political forces. As this begins to manifest, the need to safeguard Ethereum’s intrinsic machine culture becomes apparent—not merely for the sake of the blockchain but to maintain a stable foundation for emerging digital economies and governance structures.
A study to explore the motives of investors to invest in derivative markets: A PLS-SEM approach
Authors: Sanghvi Manisha , Sharma Pankaj , Chandani Arti
Published: September 2024

The objective of the study is to explore the motives of investors to invest in derivative markets. It is a quantitative study where a survey method was used to collect data from the investors using a probability sampling method. The data was analyzed using PLS-SEM to test the conceptual model. The results of the study show that speculation, hedging, and financial literacy are strong predictors of investors’ motives to invest in the derivatives market. The R2 was 0.447 implying speculation, hedging, and financial literacy explain 44.7% of the variance of the dependent variable, that is, the motives of investors to invest in equity derivatives, and the adjusted R-square is 0.432 (43.2%) which validates the model. Few studies explore the reasons to invest in derivatives using secondary data. However, to the best of the author’s knowledge studies exploring the motives of investors are rare, and there have been none using primary data from an Indian perspective. The study provides empirical evidence that could be useful to companies, investors, brokers, and policymakers to understand the motives of investors to invest in derivatives.

Authors: Ratajczak Piotr , Nowicki Jarosław , Szutkowski Dawid
Published: September 2024

The aim of the study is to examine the impact of society’s economic well-being determinants – above and beyond the firm-specific and macroeconomic determinants – on firm profitability in Poland. Based on stakeholder theory we hypothesized that the economic well-being of society can influence firm performance. Therefore, we included real wage and salary growth, internal migration, international migration, and natural increase variables in the regression models. We applied four models with different sets of variables using pooled ordinary least square regression, as well as fixed and random effects regressions with robust standard errors clustered at the firm level. The dataset covers the period from 2004 to 2021, comprising 5400 firm-year observations from Poland in the wholesale and retail trade sector. We found that firm profitability generally increases with higher inflation and exchange rate depreciation. Moreover, in models including society’s economic well-being variables, GDP growth is no longer a significant determinant of firm profitability. Most importantly, the study demonstrates a positive relationship between real wage and salary growth and firm profitability. We also found that international migration is negatively associated with firm profitability. Regarding natural increase, the study suggests that it has a positive effect on return on equity, but not on return on assets.
Public and private investments and economic growth in Ghana and Kenya
Authors: Mose Naftaly , Fumey Michael Provide
Published: September 2024

A general conception is that investment induces economic growth, but there is still debate over which type of investment contributes more to economic growth. The disaggregation of investment into public and private components allows estimation of the impact of the two types of investments on economic growth. This research, therefore, empirically estimates the relationship between each investment component against economic growth by constructing panel data for Ghana and Kenya from 1991 to 2022. The empirical strategy adopted in this study can be divided into three major stages. First, the LLC unit root test in the panel series is undertaken. Second, if integrated in the same order, a Kao co-integration test is conducted. Finally, if the series is co-integrated, the vector of cointegration in the long run is estimated using the dynamic ordinary least squares (DOLS) method. Our estimation results, based on the panel cointegration approach confirm a long-run relationship between the study variables. Further analysis shows that public investment can promote economic growth in the long run. In contrast, the results indicate that private investment can obstruct growth. The study has shown that private investment did not always increase economic growth in Ghana and Kenya. The study findings indicate that public investment is more efficiently allocated in Ghana and Kenya than private investment, suggesting the best economic strategy is for private investment to be complementary and promote higher public investment to improve public sector productivity. Therefore, policymakers should focus on creating a favourable investment climate, providing fiscal stimulus and promoting public-private partnerships to enhance infrastructure development and stimulate private -sector investment, which can sustain long-term economic growth.
Dynamic Interrelationships among Bitcoin, Bonds, and Sectoral Indices in India: Evidence from Pre- and Post-COVID-19
Authors: Sehgal Shivam , Singh Jaspal
Published: September 2024

This study employs the Maximal Overlap Discrete Wavelet Transform technique to analyze the wavelet-based correlations between Bitcoin, bond markets, and thirteen sectoral stock indices in India over the period from 2017 to 2023, focusing on the comparison of pre-and post-COVID-19 pandemic effects. The aim is to investigate the dynamic interrelationships and to understand the impact of the COVID-19 pandemic on these financial assets. The study period is divided into pre-COVID-19 and post-COVID-19. Findings from the study reveal a minimal negative correlation between Bitcoin, bond markets, and the sectoral stock indices in the pre-COVID era, indicating a lack of significant interdependence among these assets. However, the scenario changes markedly in the post-COVID period, shifting towards a positive correlation. This shift suggests that the COVID-19 pandemic has altered the relationship dynamics, leading to a more interconnected financial environment where movements in Bitcoin have begun to show a significant positive correlation with the movements in bond and sectoral stock indices in India. The study contributes to the existing literature by providing empirical evidence of how external shocks, such as the COVID-19 pandemic, can influence the correlation patterns among different financial assets. It highlights the importance of considering the changing dynamics in financial market correlations for investors, policymakers, and researchers in portfolio diversification, risk management, and financial stability analysis. Further, it underscores the role of alternative investments like Bitcoin in the evolving market landscape, particularly in response to global crises.

Authors: Farouk Didaoui Mohamed , Ismail Boughazi
Published: September 2024

This study aimed to shed light on the contribution of analytical procedures (APs) to supporting corporate governance. This was achieved through a field study in which a questionnaire was created and disseminated to a random sample of external auditors in Algeria. The data collected underwent analysis using the SPSS. The study concluded that APs play a crucial role in bolstering corporate governance by analyzing the company’s continuity capability and identifying financial problems facing the companies. In addition, APs enhance the quality and efficiency of external auditing, especially considering auditing as one of the key mechanisms that support corporate governance.
Cigarette taxation and consumption in The Czech Republic. Have these factors influenced tax revenue?
Authors: Krajňák Michal
Published: September 2024

The article evaluates the development of the tax burden on cigarettes in the Czech Republic from 1993 to the end of 2023. Tax burden is represented by effective tax rate. The research results show that the tax burden on these products is still increasing. Not only does the tax burden increase, but so does the price of these products. The regression analysis results show that quantities such as the price of cigarettes, the effective tax rate or the amount of cigarettes consumed are factories that positively influence tax revenue. Since the tax rate or the price of these products constantly increases, the tax revenue is also increasing. It increased almost six- fold over the entire analyzed period. At the same time, it was found that other factors, such as the average wage, also affect the tax revenue. It is necessary to consider that the cigarette consumption has been showing a downward trend in recent years. However, the reason is not only the increasing tax burden and the price of these products but also the transition of consumers to so-called e-cigarettes. A reduction in cigarette consumption may be reflected in the future by reducing healthcare costs, which will create potential reductions in public health insurance payments.

The presentation of landforms in two-dimensional graphics may not always be clear and understandable to every viewer. The presentation of landforms, as well as other types of characteristics and issues in three-dimensional space can bring many advantages in the process of better understanding of the surrounding reality. The primary purpose of this research is to put forward a simple scheme, accessible to any Geographic Information Systems user, for generating 3D physical terrain models for any area of the Earth. The presented scheme can be used anywhere in the world, however, for the purpose of illustrating its capabilities, a case study of a selected area – the Tatra Mountain range – was conducted in this paper. As part of the study, a 3D model was developed based on a Digital Elevation Model obtained from an open source, i.e. MapTiler. An indisputable advantage of the study is that the designed process flow in its structure takes into account only generally available tools and software (the model was prepared in the QGIS program). However, a certain limitation is the process of printing itself, which depends on the availability of specialized printing equipment. In this case study, FDM (Fused Deposition Modeling) technology was used for printing, and the model itself was prepared on a Creality Ender 7 printer. The proposed flowchart, on the one hand, unifies and simplifies the process of creating physical 3D models, while on the other hand, it provides opportunities for GIS users and developers to develop the proposed solution.
