Abstract
Floodplains are important ecosystems that contribute to the ecological stability of the landscape. A number of ecosystem functions and services are significantly influenced by ecological aspects of floodplain habitats. This article focuses on the ecological quality and estimated amount of carbon stored in the biomass of habitats located in the studied watersheds, with an emphasis on floodplains. The habitats and their ecological quality were determined and assessed using the Biotope Valuation Method (BVM), an expert method for evaluating habitat (biotope) types based on eight ecological characteristics, mainly concerning various aspects of their biodiversity and vulnerability. The objective of this study is to compare the resulting assessments of habitats located in floodplains with assessments of habitats situated in the surrounding landscape. The study was carried out on three selected small stream watersheds in the South Moravian Region of the Czech Republic, which differ from each other in terms of the predominant land use and the overall level of anthropogenic pressure on the landscape. The results indicate that floodplains have a higher ecological value compared to the surrounding landscape, except for floodplains in areas with intensive agriculture. The ability of floodplains to store carbon in biomass turned out to be higher in the watershed with a higher percentage of tree stands, where woody plants store significantly more carbon in the biomass compared to other types of vegetation. It has been shown that human pressure on floodplains and land use significantly affects ecosystem functions and services. In addition to the intensity of agriculture, these were, in particular, pressures from an expansion of built-up areas and infrastructure developments, and forest management. In this study, forest stands in floodplain were more stable and had a more beneficial species composition than forests in the surrounding landscape.
Inclusive Regional Value Chains: Blockchaining Perishable Agricultural Products in Southern Africa
Authors: Sama Hamisi K. 
Published: January 2024

Abstract
In Southern Africa due to unsystematically and uncoordinated regional value chain (RVCs), plenty of perishable agricultural products are lost because of spoilage and poor postharvest system misaligning upstream and downstream partners. Although appeal for increasing trade in Southern Africa region may seem plausible, there are strictly speaking no well-grounded economic reasons why perishable agricultural products trade should be an obsession. Broad-based inclusive RVCs through blockchaining perishable agricultural products could enable far more effective responses to region’s sustainable developmental challenges as it does in developed and emerging economies. Recently, the rise and expansion of inclusive RVCs and emphasis on blockchain has spurred major paradigm shift on revamping postharvest system. The investigate relevance of blockchaining initiatives towards inclusive RVCs to perishable agricultural products in Southern Africa. Through a quantitative research approach involving quantitative data collection methods, the research aims to assess the current challenges, opportunities, and perceptions regarding blockchain technology in the agricultural sector. Study findings practically and empirically contribute to excel blockchain for supporting development of inclusive and resilient value chains, providing insights for policymakers and stakeholders in promoting sustainable economic growth in Southern Africa’s agricultural sector.

Published: January 2024

Abstract
The study examined the performance of four machine learning algorithms (regression trees, boosted trees, random forests, and artificial neural networks) for estimating evapotranspiration (ETo) based on incomplete meteorological data. Meteorological variables (mean and maximum air temperature, average air humidity, average level of solar radiation, vapor pressure deficit, extraterrestrial solar radiation, and day number of the year) were used as input. The simulation used two calculation scenarios: data with and without average solar radiation. The performance of the different machine learning models was evaluated using the mean square error, root mean square error, coefficient of determination, and slope of regression forced through the origin between the measured and simulated ETo. The results demonstrated that the applied models were able to describe nonlinear relationships between weather parameters and evapotranspiration. The accuracy of evapotranspiration estimation depended on the type of input variables and the machine learning model used. The highest level of evapotranspiration prediction was obtained using the artificial neural networks model. Including solar radiation data in the calculations improved the quality of evapotranspiration prediction in all four models. In the absence of data on the actual solar radiation reaching the Earth's surface, it is advisable to supplement the input data with data on extraterrestrial solar radiation and the day number of the year. Such an approach can be helpful in areas and situations with limited access to meteorological data.

Published: January 2024

Abstract
As trophic organisms, nematodes play an essential role in the soil environment: they mineralize nutrients into plant-available forms, are a food source for other soil organisms, and feed on pathogenic organisms and plant pests, therefore regulating populations of soil microorganisms. The plant-parasitic nematodes are important pests of crops. Nanoparticles (NP) are increasingly used in agriculture and other production sectors. They are present in the soil, not necessarily in trace amounts, and can affect various soil organisms, including nematodes. In this article, the effects of silver (Ag), gold (Au), and platinum (Pt) nanoparticles on the mortality and reproduction activity of selected nematode species from two trophic groups: entomopathogenic nematodes (EPN) (Heterorhabditis bacteriophora and Steinernema feltiae) and plant parasitic nematodes (PPN) (Xiphinema diversicaudatum, Ditylenchus dipsaci, Heterodera schachtii) were studied under laboratory conditions. All nanoparticles decreased the nematode population to an extent depending on the nematode species, nanoparticle type, and exposure time. AgNP had the greatest nematicidal effect, except for AuNP, which reduced the population of H. schachtii the most. The greatest sensitivity to AgNP was observed in X. diversicaudatum (100% mortality), D. dipsaci (90% mortality), and 37 to 13% mortality in other species. Effect of AuNP and PtNP on entomopathogenic nematodes was comparable to the control, not treated with nanoparticles. AuNP and PtNP similarly influenced nematode mortality. However, the effect of nanoparticles on new generations of entomopathogenic nematodes developing in host larvae Galleria mellonella was inconclusive. All nanoparticles decreased the number of larvae of S. feltiae and increased the number of H. bacteriophora migrating outside the cadavers compared to the control.

Published: January 2024

Abstract
The European Nation EU is a promoter of the idea of sustainable development. Projects developed and implemented with the help of European funds can contribute significantly to the transition towards sustainability, as they facilitate innovation, development and knowledge transfer. Mainstreaming sustainability in the EU projects goes hand in hand with the development indicators set by the United Nations and, beyond that, affects regional and local development. The identification of sustainable activities requires from the beneficiaries of EU funds a good knowledge of the sustainability indicators present in the guidelines and funding applications. Even if sustainability does not have a method to be measured, it can be shown through examples of good practice in EU-funded projects. This article tries to fill this gap, contributing to a better understanding of the initiation of project activities related to sustainability by: presenting the sustainability aspects mentioned in the funding guidelines, proposing a framework for describing sustainable activities: With the help of the 5 good practice -examples of projects related to axis 4.1 Reducing carbon emissions in county municipalities through investments based on sustainable urban mobility plans we indicate examples of activities and projects aiming at sustainable urban development. In a critical discussion, we analyzed the need to build a tool to measure sustainability in projects. Finally, we draw conclusions on the potential for growth and development towards sustainability in EU-funded projects, as these projects contribute to local and therefore regional, development.

Abstract
Satellite Laser Ranging (SLR) is a modern technique used in various research areas and applications related to geodesy and geodynamics. It is commonly used for tasks such as establishing the International Terrestrial Reference Frame (ITRF), monitoring Earth Orientation Parameters (EOP), determining the geocenter, measuring fundamental physical constants, calibrating microwave tracking techniques, conducting time transfer experiments, and studying gravitational and general relativistic effects. Laser measurements of the LARES and LAGEOS satellites are used to determine the relativistic effects acting on these satellites. The objective of the present research is to analyze the perturbing forces of relativistic origin (Schwarzschild, de Sitter and Lense-Thirring effects) acting on the LARES, LAGEOS-1 and LAGEOS-2 satellites. By using data from fifteen SLR measurement stations, the precise orbits of these satellites were determined over a span of 840 hours using the GEODYN II orbital software package. The calculation process used a set of procedures, models of forces, and constants that are currently recommended by the International Earth Rotation and Reference Systems Service (IERS) and the International Laser Ranging Service (ILRS). Based on the precise orbits of the LARES, LAGEOS-1, and LAGEOS-2 satellites, calculations were made to determine the values of relativistic accelerations acting on these satellites. These values oscillate with a period equal to half of the orbital period for the de Sitter and Lense-Thirring effects, and a quarter of the orbital period for the Schwarzschild effect.
Application of Citeromyces siamensis for Molasses Wastewater Decolourization

Published: January 2024

Abstract
Molasses, a brownish black viscous liquid, is a byproduct of the cane sugar process. It finds applications in various industries such as fertilizer production, animal husbandry, alcohol production, monosodium glutamate production, and the production of acetic acid. In Thailand, it is primarily used for alcohol production and as animal feed. However, molasses wastewater is characterized by high levels of biochemical and chemical oxygen demand, as well as suspended solids. Untreated release of this wastewater into the environment can lead to numerous environmental issues. Additionally, the presence of melanoidins in molasses wastewater makes its removal challenging, resulting in a dark colour of the treated water. Discharge of this dark-coloured water into natural water sources can lead to an abnormal discolouration of the water. This study aims to investigate the optimal conditions for utilizing Citeromyces siamensis microorganisms in the biological treatment of molasses wastewater. The experiment was conducted to determine the conditions that facilitate the reduction of colour in molasses wastewater. The findings indicate that the addition of 1 % glucose and 1 % peptone was more effective in decolourizing molasses wastewater using Citeromyces siamensis compared to other nutrient additions. While the addition of additives may incur additional costs, it remains a more economical option compared to the use of chemicals for wastewater colour removal. Furthermore, the use of the additives is considered safe for living organisms.
Expat Vlogs: Bilingual Couples Share their Lives on the Internet
Authors: Stępkowska Agnieszka , Buczek Katarzyna 
Published: January 2024

Abstract
As there are more and more bilingual couples who ran vlogs to share their bilingual and intercultural lives on the internet, this paper seeks to delineate the sources of motivation for these couples to disclose their privacy through vlogging. Based on the sample of selected vlogs, a qualitative analysis has been conducted to obtain the sociolinguistic picture of the bilingual couples’ motivations to attract wider audiences via the internet. The analysis of vlogs, informed by a multimodal theoretical framework, focused on the audiovisual and textual content of vlogs with regard to the subjective representations of films and texts resulting from these couples’ individual stories. The conducted study spotlights vlogging activities of bilingual couples who feel the need to share their intercultural and bilingual experiences on the internet. Our data suggest that bilingual couples vlog to express their hybrid identities by sharing how they cope with challenges and overcome linguistic barriers, as well as find ways to enjoy cross-cultural understanding. The paper explores the linguistic and cultural diversity from a new perspective of private vlogs created and maintained by bilingual couples. It unfolds an account of the less studied online context in which partners of different ethnic backgrounds make their private lives public, and illustrates how bilingual couples generate ideas to filming and sharing online.

Published: January 2024

Abstract
The occurrence of business cycles is a feature of every economic system, so they were also observed in Poland. The article is an attempt to assess the structure and most important morphological features of the business cycles in Poland’s economy, taking into account how they were influenced by the consequences of the financial crisis 2007+ and COVID-19 pandemic. In the study the authors used the concept of deviation cycles which makes it possible to characterize the components of the business cycle’s structure, i.e. identification of its turning points, particular phases and most important morphological features (i.e. duration of phases and the whole cycle, amplitude of fluctuations). The most significant empirical indicators which characterize the real cyclical processes, i.e. GDP, consumption and investment, were the subject of statistical analyses.

Published: January 2024

Abstract
The paper presents, in the synthetic way, the issue of the rationality of the tax system and taxation principles in relation to the clearly visible fiscal crisis in the 21st century caused by, among others, COVID-19 pandemic. The analysis which is theoretical (descriptive, comparative) was carried out by using tools indicated in the area of New Institutional Economics (NIE). Attention was devoted primarily to the importance of specific institutional arrangements, broadly understood as the “rules of the game” applicable in the political and economic spheres, and related to the problems of public finances. Research has shown that the appropriate design of tax rules may contribute, to some extent, to limiting the fiscal crisis. Tax policy, and even more broadly, fiscal policy, may determine the formula in which the economic achievements regarding compliance with tax principles and fiscal rules can be implemented. What is primarily important is the legal framework (one of the most important formal institutions) within which state policy in the field of public finances should be implemented.

Published: January 2024

Abstract
The presented study raises the issue of contribution payers in the field of social insurance, in particular based on the Covid-19 pandemic. Searching for ways of supporting was determined by the deterioration of the financial condition of entrepreneurs as payers of contributions. In 2020, there were no instruments or mechanisms to support entrepreneurs in a lockdown situation, which implied the need to build such tools and the legal environment for SMEs practically from the beginning. The Social Insurance Institution (ZUS) was entrusted with the role of a stabilizer, consisting in servicing entrepreneurs as part of subsequent editions of the Anti-Crisis Shield. During the announcement of the COVID-19 pandemic, ZUS used the following forms of support for contribution payers: exemption from the obligation to pay contributions, postponement of the payment of contributions and payment of contributions in installments. The research question concerned the enforcement of the law and respect for the basic rights of entrepreneurs in the scope of the support used. In order to solve the research task legal interpretation were used in the work. The author’s considerations lead to the conclusion that forms of support used in connection with the Covid-19 pandemic turned out to be effective and may be used in the future in emergency situations. An important science contribution of the article results from the combination of the selected legal and economic aspects.

Communication technology has recently become a new medium where society can choose information and the media they want to consume. The media can still influence their minds. Based on the National Survey of Internet User Penetration Data, in March 2019, by APJII (Internet Service Provider Association), the internet penetration rate in Aceh was recorded at 64.40% who accessed the internet. This research aims to find Acehnese's Digital Literacy Skills in Verification News from Social Media. The data collection method used for this study is a questionnaire instrument via Google Form to people in Nanggroe Aceh Darussalam (NAD) province. Meanwhile, secondary data was collected through literature studies and previous research. The result shows that the people of Aceh, especially millennials and Generation Z, have enough digital literacy skills to access digital media, understand content, and verify news.
Bibliometric Analysis of the Trend of Sociology of Communication Research Topics
Authors: Purnomo Agustina Multi 
Published: January 2024

Bibliometric analysis can provide extensive data mapping of previous research topic trends to formulate subsequent research topics. There is still a lack of bibliometric analysis of trends in sociology of communication research topics. The study used bibliometric analysis of 37,999 publications in ScienceDirect over three periods. Publication data was selected using the keyword "sociology of communication." Data processing was conducted by co-occurrence between keywords and data presentation with overlay visualization. The results of data processing with VosViewer revealed shifts in research topics over three periods. Topics that emerged after 2022 are related to Covid-19 pandemic, such as healthcare, resilience, stress, and vaccine hesitancy; methodologies like systematic literature review; recent technologies such as artificial intelligence; and other societal concerns, including sustainability. That topic was suggested for future research. However, sustainability and systematic literature review are old issues in other research fields. The research found that the sociology of communication research topics is changing dynamically and is influenced by social phenomena such as pandemics and technological advancements. The presence of two recent topics that have become old issues in other fields of social research shows the challenge for communication scientists to respond responsively to global social and methodological issues.
The Role of Social Media in Improving Tax Compliance in the Theory of Planned Behavior
Authors: Zikrulloh Zikrulloh 
Published: January 2024

The government always strives to improve tax compliance to achieve the target of state revenues. In practice, the government has initiated the use of social media as a communication medium to disseminate information, education, and interaction to the broader citizens. This study aims to determine the role of social media in improving individual tax compliance using the Theory of Planned Behavior (TPB) approach. The data collection technique was carried out using an online survey method with a questionnaire instrument. The data analysis was conducted using the Structural Equation Modeling (SEM) Model to test the relationship between variables in a model. The study results show that the attitude variable on taxpayers intention has a p-value = 0.064 > 0.05 with a coefficient of -15.7%. In line with the attitude variable, the subjective norms variable has a p-value = 0.670>0.05 with a coefficient of 3.1%. On the other hand, the perceived behavioral control has a coefficient of 20.1% (with p-value <0.05), the tax moral obligation variable has a p-value = 0.000 < 0.05 with beta = 28.7%, and the use of social media also has p-value < 0.05, with a coefficient of 39.4%. The use of social media positively and significantly influences the individual taxpayers’ intention to behave in tax compliance. Adding social media variables to the study also broadens the implementation of TPB theory from a communication studies perspective, and gives recommendations to the government to improve the quality of information content appropriately through social media.
