Published: June 2024

La evaluación social de los impactos de los proyectos agroecológicos es una importante vía para perfeccionar la sostenibilidad y resiliencia social de los agroecosistemas. La investigación tuvo como objetivo valorar los impactos sociales del proyecto Boyacá-Agro en dos municipios del alto y bajo Ricaurte en el departamento de Boyacá. Se aplicó un cuestionario de diez preguntas a los quince beneficiarios de cada finca por municipio con el fin de medir el impacto en cuatro dimensiones: la gestión del conocimiento, la gestión tecnológica, sobre la finca, la familia y la comunidad, y el liderazgo del agricultor. La gran mayoría de los beneficiarios (más de 55%) opinó que los impactos eran altos o muy altos en la gestión del conocimiento, la adopción de nuevas tecnologías, en la mejoría de las familias y las fincas, y el crecimiento de los jefes de fincas como líderes agroecológicos; sin embargo, no fue así en cuanto al reconocimiento ante la comunidad.
The Legal, Explanatory, and Expert Aspects of the Concepts Utilized By Lawmakers in Enacting the Prohibition of LGBT Propaganda
Authors: Medvedeva A. S.
Published: June 2024

The article analyzes new concepts introduced by Federal Law No. 478-FZ of December 5, 2022, such as propaganda of non-traditional sexual preferences, pedophilia and gender reassignment. The aim is to comprehend the significance of the mentioned categories and their potential ramifications on law enforcement practices and forensic activities. The meaning of these terms is primarily considered based on the sociocultural context. The assessment of the level of traditionalism regarding sexual preferences and gender-fluid behavior is conducted uniquely within specific societies, governed by their respective rules and norms. It is noted that the international and Russian societies hold qualitatively distinct attitudes toward these phenomena. Special attention is paid to the analysis of propaganda of the phenomena under consideration. It is noted that in Russian society, propaganda is not always correctly interpreted; often it is replaced by the categories of 'justification' and 'call to action,' which have different meanings. In particular, the category "pedophilia propaganda" is considered, the contradictory nature of the result of the joint use of these nominations is emphasized: if pedophilia is understood as a disorder of sexual preference, its propaganda is impossible. Based on this logical discrepancy, a conclusion is made about the possible need to amend criminal, criminal procedure and penal enforcement legislation. The author presents definitions for the three terms under discussion. Regarding the propaganda of non-traditional sexual preferences, pedophilia, and gender reassignment, the article's author proposes understanding it as the persuasion of the general audience in the validity and necessity of embracing corresponding ideologies. The potential for forensic expert engagement in detecting distinctive markers of propaganda related to the discussed phenomena is outlined. A three-stage algorithm for expert analysis is suggested: identifying the central theme of contentious content, discerning the author's stance and inclination towards shaping the audience's receptiveness to the declared viewpoint. The overarching conclusion is drawn that the enactment of laws prohibiting LGBT propaganda necessitates continued collaborative efforts among a diverse range of specialists. These efforts should be directed towards establishing a shared understanding of the new terms, addressing clinical, diagnostic, and legal challenges, and developing methodological frameworks to support law enforcement and expert activities.
Mobile Money Taxes: Knowledge, Perceptions and Politics. The Case of Ghana
Authors: Abounabhan Mary , Diouf Awa , Santoro Fabrizio , Sakyi-Nyarko Carlos , Scarpini Celeste
Published: June 2024

Consumer-level mobile money taxes are particularly controversial, and have sparked large-scale protests – prompting policy revisions in various countries, including Uganda, Côte d’Ivoire, and Benin. Ghana’s electronic transfer levy (e-levy) followed this trend of public dissent, and triggered the country’s first budgetary rejection since 1981. Not surprisingly, the trend in mobile money usage in Ghana showed a sharp decrease in overall volume and value of mobile money transactions after implementation of the tax. This was followed by a gradual rise back to usage before the e-levy, coinciding with a reduction in the rate. The strong reaction and trend in mobile money usage after revision make understanding what lies behind public perceptions and behaviour especially important for informing the ongoing debate within Ghana and the region. Summary of ICTD Working Paper 183.

Published: June 2024

Banana peel contains starch, protein, fat, total fiber, unsaturated fatty acids, pectin, amino acids, polyphenols and micronutrients. Horn banana peelhas many benefits, namely it can be processed into a natural antioxidant material that can minimize banana skin waste. The banana peel extraction method used is Ultrasound Assisted Extraction. Ultrasound Assisted Extraction at optimal conditions produces good levels of total polyphenols with a short extraction time. In the use of ultrasonic no additional chemicals or other materials are needed. This study aims to determine the effect of extraction time (10, 20, 30 minutes), extraction temperature (20, 30, 40℃) and solvent ratio (gr/mL) (1:25, 1:30, 1:35) on polyphenols. The Design Expert V13 program with Response Surface Methodology (RSM) Box-Behnken Design (BBD) was used to determine the combination of extraction parameters that lead to optimal results for total polyphenol content. Based on the research that has been done, it can be stated that the extraction parameters affect the total polyphenol content. The highest total polyphenol content was 61,007 mg GAE/g sample with the extraction conditions at an extraction temperature of 30℃, an extraction time of 30 minutes, and a ratio of banana peel powder to a dissolution of 1:30 g/mL.

Patterns of deadwood volume and dynamics in Slovenian forests
Authors: Kušar Gal , Neumann Mathias
Published: June 2024

Deadwood, and its temporal and spatial variation, plays an important role in several forest ecosystem services. This study demonstrates the assessment of deadwood dynamics using data from Slovenian national forest inventory permanent sampling plots, employing a mass-balance approach. Our results reveal that deadwood volume is a highly variable metric across regions, deadwood types and tree species. Despite the influx of large volumes of new deadwood due to recent natural disturbances, only moderate increases in deadwood volume were observed between 2007 and 2018. This was mainly offset by deadwood losses due to salvage logging and decomposition. The extent of deadwood losses varied considerably by species. We discuss the implications of the calculation method on estimating changes in deadwood volume, compare these findings with existing literature on deadwood and highlight promising areas for future research activities to better understand deadwood dynamics.

Published: June 2024

The mining tradition in Litija, dating back to the Iron Age, involved the intensive use of wood in the mines, especially for support and protection. The Sitarjevec mine was reopened for tourism in 2017, and the central tunnel was opened in 2021. Wood remains a key material in the mines, although other materials have replaced it in the past. The wood used is subject to decay due to high humidity and fungi such as the mine fungus. This fungus can cause wood decomposition and is common in the humid environments of mines. The presence of fungi is important as it can affect visitors to the mine. The high relative humidity (96.6%) and constant temperature (10.1°C) in the mine create favourable conditions for fungal growth, although the relatively low temperature is not a limiting factor for wood decay. The high concentration of fungal spores in the mine is explained by the presence of fungi in the mine itself. In addition, we have observed that the wood contains a high level of inorganic contaminants and many crystals.

Published: June 2024

Amidst the urgent demand for carbon-neutral strategies, electrocatalytic hydrogen evolution reaction (HER) has garnered significant attention as an efficient and environmentally friendly energy conversion pathway. Non-precious metal layered transition metal carbides, particularly various modified two-dimensional molybdenum carbides (2D Mo2C), have emerged as promising HER catalysts due to their superior intrinsic catalytic activity. While common non-metal doping strategies have been widely employed to enhance the electronic configuration and bulk/interface activity, the mechanism of HER performance dependence on the doping-induced electronic configuration in 2D Mo2C remains unclear, especially for more complex binary or ternary doping configurations. To address the issue of uncontrollable doping atom percentages in conventional methods, herein, we propose a strategy for rapidly synthesizing highly tunable non-metal multielement-doped 2D Mo2C using microwave pulse-assisted synthesis. By designing doping configurations with similar atomic ratios, we delve into the impact mechanisms of various doping configurations on the HER performance of 2D Mo2C, with phosphorus doping potentially exerting the most significant positive influence. Furthermore, leveraging the unique thermodynamic and kinetic advantages of microwaves, this approach efficiently prevents potential side reactions associated with multi-element doping, enabling the rapid and precise synthesis of binary and ternary-doped 2D Mo2C. The synthesized ternary-doped 2D Mo2C with the same doping atomic ratios (2D P,N,S-Mo2C) exhibits outstanding HER performance. This method not only offers a novel approach for precisely designing non-metallic atomic doping configurations in 2D TMCs but also provides insights into the theoretical structure-activity mechanism for other carbides with unique structures.

Theoretical and Numerical Investigation of Mechanical Properties of Auxetic S-structure under Transverse Load
Authors: Mondal Prasanna , R. Jayaganthan
Published: June 2024

A significantly reduced stress concentration effect and a stable deformation behavior are exhibited by the arc-like S-shaped auxetic structure. Analytical works beyond the bar and hinge method to capture structural effects, such as bending, shearing, etc., in the S-structure are scarce in the literature. The deformation pattern of the S-structure is dominated by bending and shearing within the linear elastic region. In this work, Timoshenko beam theory is used to derive closed-form expressions for overall elastic modulus and Poisson’s ratio. This agrees well with the results of finite element simulations. An adjusted R-square value of over 0.99 and almost 0.82 is obtained for elastic modulus and Poisson’s ratio, respectively. From parametric studies, it’s established that under quasi-static transverse load, strut thickness and the angle `α’ are the most important parameters for controlling elastic modulus, specific energy absorption, negative Poisson’s ratio (NPR) effect, and relative density of the entire auxetic structure. Also, it’s found that energy absorption and elastic modulus increase together. Interestingly, the elastic modulus of the structure under transverse load lies in the range from 3 MPa to 250 MPa, which means this structure is compliant enough and can be used in cushioning, packaging, soft robotics applications, etc.

Authors: Jeong Junyoung , Cho Keuntae
Published: June 2024

As the digital transformation accelerates in our society, open data is being increasingly recognized as a key resource for digital innovation in the public sector. This study explores the following two research questions: 1) Can a machine learning approach be appropriately used for measuring and evaluating open data utilization? 2) Should different machine learning models be applied for measuring open data utilization depending on open data attributes (field and usage type)? This study used single-model (Random Forest, XGBoost, LightGBM, CatBoost) and multi-model (Stacking Ensemble) machine learning methods. A key finding is that the best-performing models differed depending on open data attributes (field and type of use). The applicability of the machine learning approach for measuring and evaluating open data utilization in advance was also confirmed. This study contributes to open data utilization and to the application of its intrinsic value to society.
Rock Art and the Reconstruction of a Paleoenvironment:
The Case of Alces alces in the Mongolian Altai
Authors: Jacobson-Tepfer Esther
Published: June 2024

This paper considers how prehistoric rock art can illuminate the environmental conditions of a vast but poorly known region in the distant past and in the process shed light on issues of environment, faunal survival, and cultural change. The rock art being considered here is located in the Baga Oigor valley of Bayan Ölgiy aimag, northwestern Mongolia; together with the petroglyphic complexes of Tsagaan Gol and Aral Tolgoi, it is part of the largest, most ancient, and best–preserved body of rock art in this mountainous region dividing North and Central Asia. The Baga Oigor complex itself includes materials dating from the late Paleolithic (12,000 yrs BP) through the Turkic Period (mid-first millennium CE). Within the thousands of compositions included in the complex, one of the least noticed images is that of the moose (Alces alces). Yet as much as any other animal representation within the petroglyphs of Baga Oigor, this image reveals the radical transformation of the environment of the Altai Mountains over several thousand years and its cultural implications. The examination of Alces alces and of its pictorial contexts sheds light on a world inhabited by ancient hunters and herders and sharpens our understanding of the dynamics of cultural change.

Authors: Yu Tao , Ma Xuena , Zhang Jianguo , Cao Jingsheng , Cao Shiliang , Li Wenyue , Yang Gengbin
Published: June 2024

Abiotic stress is a significant factor restricting the normal growth and development of plants. Under abiotic stress, plants maintain their life and continuous growth by reconfiguring transcriptional regulation and metabolic networks. In recent years, with the development of sequencing technology and mass spectrometry technology, transcriptomics and metabolomics have emerged as new disciplines following genomics and proteomics, which are conducive to identifying metabolites and regulatory genes in plants under abiotic stress. In this review, we mainly analyzes the technical characteristics, advantages, and disadvantages of transcriptomics and metabolomics, focusing on reviewing the research progress in the field of plant responses to abiotic stress (temperature stress, salt stress, water stress, and heavy metal stress) using transcriptomics and metabolomics both domestically and internationally in recent years. It also provides a prospective view on current issues, which helps accelerate the understanding of the mechanisms of plant responses to abiotic stress and provides new ideas for breeding stress-resistant varieties in the future.
A Framework for Requirements Management to Develop Safety Management and Operation of Maritime Autonomous Surface Ships
Authors: Umeda Ayako , Shimizu Etsuro
Published: June 2024

Following technological advances, autonomous and remote-controlled ships are performing trials in some sea areas; a mandatory goal-based MASS code, expected to enter into force on 1 January 2032, is under discussion in the International Maritime Organization (IMO). However, there are no unified standards regarding verification methods to define operating limitations for cutting-edge technologies, which are expected to be elements of MASS, so it is difficult to assess the risk factors for the management and operation of MASS. This paper outlines the regulatory framework for MASS, followed by a discussion of its application, considering the differences between MASS and automated driving, and how to develop safety management and operation using standards for automated driving. A requirements management framework developed as a system and software engineering standards to build safety management and operation of MASS is proposed. It is also suggested that the requirements management framework could be used not only for MASS development but also for regulatory review from a requirements management view.

In this work, to gain a complete understanding of quark color theory in the framework of complex octonionic space, we have derived the relationship between octonions and the SU(3)c color group. With the help of Feynman diagrams, we examined the octonionic interaction of color quarks (such as quark-quark, quark anti-quark, and anti-quarks anti-quarks interactions). For the interactions, we have obtained the octonion algebraic form of the interaction term, propagator, vertex factor, and color factor.
Exploring Consumer Trust in Supply Chain Certifications and Its Impact on Marketing Effectiveness
Authors: Holloway Samuel
Published: June 2024

Consumer trust in supply chain certifications plays a pivotal role in shaping contemporary consumer behavior and marketing effectiveness. This qualitative research investigates consumer perceptions of supply chain certifications and their impact on purchasing decisions and brand loyalty. Through semi-structured interviews and focus group discussions with 30 participants, the study explores themes such as credibility, transparency, perceived value, and the influence of certifications on consumer trust. Findings reveal that consumers value certifications that signal ethical sourcing practices and sustainability commitments, viewing them as assurances of product quality and social responsibility. Credibility and transparency in certification processes emerged as critical factors influencing consumer trust, while perceived benefits such as environmental sustainability and fair labor practices positively influenced purchase intentions. Moreover, certifications were found to enhance brand loyalty by aligning with consumers' ethical values and beliefs. However, the study identifies challenges including high certification costs, complexity in compliance, and consumer skepticism, which hinder broader adoption and effectiveness of certifications. The implications of these findings suggest that businesses can enhance consumer trust and market competitiveness by investing in rigorous certification standards, clear communication strategies, and sustainable practices. Addressing barriers through improved transparency and consumer education is crucial for maximizing the impact of certifications on ethical consumption. Future research directions include longitudinal studies on certification impacts and comparative analyses across industries and global markets to further enrich understanding of consumer behavior and certification influences.
A Review on Radiopaque Polyurethanes: Materials, Processing, and Properties
Authors: Garavatti Julia , Jr. Heitor Luiz Ornaghi
Published: June 2024

It's been a growing concern that many microbes are developing resistance against many antibiotics, lowering the effectiveness and progress expected from that treatment option. To overcome the re-sistance developed by microbes, metallic and non-metallic-based nanoparticle treatments are starting to present a very promising approach. Furthermore, polyurethanes are used in a wide range of biomedical applications due to their variety of physical-chemical, mechanical, and structural properties, and biotic and abiotic degradation. They are widely used in bio-imaging procedures when metallic-based filler particles are incorporated, making the final product radiopaque. It would be advantageous, however, if polyurethanes with intrinsic radiopacity could be produced in their synthesis, avoiding a series of disadvantages in the processing and final product and also presenting potential antimicrobial activities. This review’s objective was to study the radiopacifying charac-teristics of nanoparticles as well as the physical principles of radiopacity and the variety of medical applications of polyurethanes with nanoparticles. It was found in this study that the synthetization of radiopaque polyurethanes is not only possible but also that the efficiency of synthetization was improved when using atoms with high electron density as part of the back chainbone or grafted, making them great multipurpose materials.

Published: June 2024

The relentless advancement and integration of mechanization and intelligence within the coal mining industry, combined with the increasing depths of mining operations, necessitate significantly higher safety standards. This necessity arises due to the increasingly complex geological and coal seam conditions encountered as mining operations delve deeper into the earth. Traditionally, 3D seismic exploration technology has been fundamental in ensuring both operational efficiency and safety in the coal mining sector. However, despite its critical role, this technology still has limitations in detecting and characterizing small-scale geological structures which can pose substantial risks if not accurately identified and mitigated. To address these challenges, this paper introduces a sparsity-constrained adaptive hard thresholding algorithm designed to tackle the spectral inversion optimization problem with an norm constraint for the enhanced retrieval of reflection coefficients, thereby establishing a comprehensive workflow for enhancing seismic data resolution through compressed sensing spectral inversion. Real data validation has demonstrated that this method significantly enhances the resolution of seismic data while maintaining the amplitude integrity and fidelity of the original signals. This improvement allows for a more detailed and accurate characterization of small-scale geological features, which are critical in identifying and mitigating potential hazards within coal mining operations, thus offering robust support for the implementation of more effective safety protocols and disaster prevention strategies in coal mines.

Numerous investigations have suggested that seismic source parameters and properties of the surrounding medium harbor valuable information regarding alterations in stress fields and medium properties at the focal depth. Monitoring the spatial and temporal evolution of these parameters can yield insights into variations in stress fields or medium properties within the seismogenic zone, offering a critical avenue to overcome the Earth's inaccessible nature. In recent years, modern seismic parameters such as seismic moment, focal mechanism solution, source stress drop, corner frequency, radiated seismic energy, rupture radius, and apparent stress have been increasingly used to characterize source characteristics. The Sichuan region is situated on the southeastern edge of the Qinghai-Tibet Plateau and is known for its strong eastward extrusion and structural deformation. The main fault zones in the area include the Xianshuihe Fault, Anninghe Zemuhe Fault, and Longmenshan Fault. This paper estimates source parameters of small to medium-sized earthquakes (ML 1.5-5.2) in the main fault zones and adjacent areas in Sichuan. A total of 4,310 earthquake stress drop measurements from 2019 to 2023 were analyzed to create a stress distribution image along the fault. This earthquake parameters training catalog provides insight into how coseismic stresses change and their relationship with other geophysical factors, as well as their spatial and temporal evolution.

Published: June 2024

This paper provides a retrospective analysis of published COVID-19 data and focuses on Costa Rica as an example of data analysis and validation in developing countries. The COVID-19 outbreak has highlighted the importance of robust health systems and adequate resources to test and manage diseases. However, due to limited resources and excessive burdens, developing countries face unique challenges in this regard. This makes it difficult to conduct widespread testing. The lack of testing kits, laboratory facilities, trained personnel, and the necessary infrastructure is a significant barrier. Additionally, logistical issues such as transportation and distribution of testing kits in remote areas further complicate the situation. On the other hand, universal healthcare in developing countries, despite the lack of extensive testing, can still provide reliable data on the spread and impact of the disease. Universal healthcare can lead to better records keeping and data collection, as all individuals, regardless of their economic status, have access to medical services. This inclusivity ensures a more comprehensive and representative data set. Therefore, while testing is an important tool in managing the pandemic, universal healthcare systems can still provide valuable insights in its absence. This description can be applied to the Costa Rica COVID-19 scenario: lack of resources for an adequate testing methodology but a universal healthcare system that ensures inclusivity. In this work, we show that the number of active cases of COVID-19 for Costa Rica does not provide reliable information that can be used to adjust the parameters of a mathematical model, so the effectiveness of the contention measures cannot be precisely stated. However, the number of hospitalizations is more reliable in the centralized and universal healthcare system, but quantifying the effectiveness of such measures requires a different set of tools. Traditionally, most pandemic data analysis is based on the estimation of the Rt number based on the number of active cases. We propose a methodology based on digital signal processing principles and elementary differential calculus. To our knowledge, these kinds of methodologies have not been of widespread use in pandemic data analysis, and, as we show, they may provide a valuable descriptive analysis of pandemic tendencies and they are an accessible, fast and reliable decision-making tool.

Objective: To explore the functions that physical activity (PA), life satisfaction, and self-efficacy have in the process of coping with anxiety among Chinese college students, and to explore the mediating role of life satisfaction and self-efficacy in this process.
Methods: Participants were 358 college students (186 males, 172 females, mean age 20.88, SD=±1.80). Psychosocial tests including the Physical Activity Rating Scale (PARS-3), College Student Life Satisfaction Scale (CSLSS), General Self-Efficacy Scale (GSES), and Generalized Anxiety Disorder Scale (GAD-7) were completed. Correlations between variables were calculated using Pearson's test. The mediation model was tested using the SPSS 26.0 PROCESS macro and regression bootstrap.
Results: Physical activity showed a negative correlation with anxiety (β= -0.1617, p < 0.001), life satisfaction and self-efficacy played a role in the relationship between physical activity and anxiety, and, more importantly, physical activity affected anxiety through the parallel mediating effects of life satisfaction and self-efficacy, with a total mediating effect of 55.34%.
Conclusion: By increasing college students' participation in physical activity, it helps to promote the growth of their life satisfaction and self-efficacy, which is the key to reducing anxiety and promoting college students' mental health.
