Value Chain Analysis of Haricot Bean in East Shewa Zone, Oromia Regional State, Ethiopia
Authors: Bati Beriso
Published: November 2024

The key objectives of the study were identifying haricot bean value chain actors, their functions and relationship among them, examining actor’s performance along the chain and analyzing factors affecting supply to the market and factors affecting market outlet choice in the study area. Both primary and secondary sources were used for data collection. The primary data was collected through interviewing 180 sample household farmers and 40 traders using semi-structured questionnaires. STATA version 15 Software was used for data analyzing. As the descriptive result indicate that, on average farmers allocate 0.72ha of land for haricot bean production, from which 21.72qt/ha of output gained. In the value chain of haricot bean input suppliers, farmers, collectors, traders, transporters and consumers are the major value chain actors who perform various value chain. From the study result, six marketing channels of haricot bean are exhibited in the study areas. Estimates of the multiple linear regression models indicate that the level of haricot bean supplied to the market is determined by educational level of household, haricot bean farming experience, land allocated for haricot bean, market price of haricot bean, TLU, access to credit, and access to market information. Therefore, policy makers should focus more on the abovementioned variables in the future intervention to increase volume of haricot bean supplied to the market. As the multivariate probit model result indicated that the market outlet choice of rural assemblers was positively and significantly influenced by distance to the nearest market center, distance to all weather road, and educational level whereas it’s negatively and significantly influenced by output level where as selling direct to consumers outlet choice was negatively and significantly affected by sex of household, educational level, farm experience of household in haricot bean, and output level. Urban traders/wholesalers market outlet was positively and significantly affected by sex of household, educational level, haricot bean farm experience, access to credit, access to market information, membership of cooperative, and output level whereas it’s negatively influenced by distance to the nearest market center, distance to all weather road and extension service. Based on the findings of this study, some relevant implications can be drawn that can assist to design appropriate intervention mechanisms to improve market outlets choice of haricot bean farmers in the study area.
Citizens’ Political Knowledge and Participation in Monitoring Local Government Programs in Two Districts of Uganda
Authors: Kaddu Ronald , Makara Sabiti
Published: November 2024

Broad political knowledge better equips citizens to discharge the responsibilities of good citizenship, such as monitoring local government programs. Empirical studies show a connection between citizens’ political knowledge and their participation in monitoring activities in contexts other than a decentralized local government system in a developing country. Thus, in this paper, we set out to provide new empirical evidence by assessing the link between citizens’ political knowledge and their participation in monitoring local government programs in Buliisa and Kampala districts of Uganda. We employed a convergent parallel research design. We gathered data using survey questionnaire, key informant interviews, and focus group discussions. We analyzed quantitative data using STATA and performed thematic analysis for the qualitative data. Generally, results showed that the level of political participation of citizens in monitoring local government programs was significantly and positively associated with their level of knowledge of local political affairs. This was especially marked in Kampala compared to Buliisa district. Conclusively, the nature of the association between the aforesaid variables could differ depending on the form of local political knowledge and/or the nature of political participation being measured.
The Financial Inclusion Question in Zimbabwe’s Post-COVID -19, New Normal: Implications for Adoption of Financial Technology (FinTech) on Service Providers
Authors: Oscar Nyamunokora , Gideon Zhou
Published: November 2024

Financial inclusion will be accelerated by the technological opportunities for online financial transactions brought forth by the COVID-19 outbreak. As a result, because there were fewer digital financial transactions, the threats to COVID-19 that were present previously are now more substantial. The aim of this article is to assess the dangers, challenges, and opportunities for financial inclusion brought forth by the use of technology by COVID-19. According to the article, the inherent characteristics of financial technology (FinTech) in connection to financial inclusion allow it to reduce the negative economic and social effects of the ongoing COVID-19 situation. Under COVID-19, the introduction of digital financial transactions has sped up corporate operations and cut expense on doing business. As a result, women now have greater access to transactions involving financial technology (FinTech). The growth of digital financial transactions has made contactless and cashless purchases possible throughout the COVID-19 crisis. The expansion of digital financial inclusion makes it easier to swiftly and effectively implement public assistance programs, such as those for epidemic-affected women. Financial inclusion is being boosted by digital finance, which may eventually replace or improve traditional banking institutions. Working from home has undergone a "revolution" in a number of industries during COVID-19, including banking. Businesses should identify the optimal operating model mix for the future and make sure they have the infrastructure to support widespread, mass flexible working. This calls for reevaluating the function and application of corporate real estate. Since the labor force is likely to become more automated at the same time, resilience is essential. Conceptual Framework of this study is based on the financial inclusion and FinTech concepts which are the main variables guiding the study and it is underpinned by the theories of diffusion of innovation and the Financial Intermediation.
Exploring the Inclusivity and Gender Disparities in Accessing Critical Agriculture Resources in Rural Areas. Drawing Lessons From the Government of Zimbabwe’s Land Reform Policies
Authors: Oscar Nyamunokora , Zinyama Tawanda
Published: November 2024

In order to determine how much rural women in Zimbabwe are aware of their rights, the essay compares their status to that of rural males in certain fields. According to research, the majority of women in the nation are not allowed to participate in national development efforts because of societal beliefs, gender-based violence (GBV), bias against women, gender inequality, and low economic position. According to research, women could boost yields between 20 to 30%, reducing poverty and improving food security, if they had equal control and access over productive assets as males. According to an analysis of poverty trends, women have historically and continue to be disproportionately affected by poverty in Zimbabwe. It is commonly known that the Zimbabwean Constitution is steadfastly committed to inclusiveness and gender equality. The Constitution's dedication to tackling gender inequality is upheld through the affirmative action clauses. Equal civil rights currently apply to both men and women. One of the objectives for the government, all institutions, and governmental organizations is gender parity. Men and women have a fundamental right to be treated equally, which includes the right to equal chances in the political, financial, cultural, and social arenas, as stated in the Bill of Rights found in Chapter 4 of the new Constitution.

Subject. At the present stage of development, migration processes are considered as one of the fundamental factors influencing the formation of society. Migration processes are one of the key population problems and are interpreted not only as the movement of citizens, but also as a complex social process that affects many socio-economic aspects of life. Goal. Research and assessment of international labor migration in modern conditions. Method or methodology. In the course of the work, general scientific methods were used: comparison, analysis, synthesis, analogy, as well as rating. Results of the work. For 2018–2021 there is a positive migration balance, i.e. the number of arrivals in the Russian Federation is greater than those leaving. The main influx of migrants comes from the CIS countries, and a large share of them is a labor force with a fairly low level of professional training. At the same time, one of the characteristic features of migration in Russia is the uneven distribution of flows across the territory of the state. Most migrants are sent, as a rule, to the Central and Northwestern federal districts, since they are the most economically attractive for migrants. Conclusion. Taking into account previously identified trends and research into foreign experience in migration policy, the following directions have been formulated: in the field of interstate regulation of labor migration, taking into account agreements with foreign countries – Russia’s key migration partners; in the field of general issues of regulating labor migration in the interests of the Russian labor market; in the field of ensuring working and living conditions for migrant workers; in the sphere of integration of some migrant workers into Russian society; in the field of improving the system of statistical accounting and monitoring of labor migration.

Ukraine and US-NATO in the Russia-Ukraine War
Authors: Alex Kung-Hsiung CHANG Alex Kung-Hsiung CHANG , Alex Kung-Hsiung CHANG Yi-Chen SHI
Published: November 2024

The Russia-Ukraine war broke out on February 24, 2022, shaking the international community. To understand the behavior of both Russia and Ukraine in this war, as well as how military and economic aid from the United States, the European Union, and NATO influences Ukraine’s actions, this paper explores the interaction between Ukraine and the U.S.-EU alliance through the viewpoint of welfare game theory. The discussion focuses on how these interactions affect the progress of the Russia-Ukraine war. International political and military activities are based on national interests. The U.S.-EU alliance’s support for Ukraine in resisting the Russian invasion must consider the mutual interests, losses, and related conditions between the U.S., EU, and Ukraine.

Causal Links Between Renal Function and Cardiac Structure, Function, and Disease Risk
Authors: Zhou Xiaoqin , Ruan Weiqiang , Zhao Lijun , Lin Ke , Li Jing , Liu Huizhen , Wang Ting , Zhang Guiying
Published: November 2024

Background: Chronic kidney disease (CKD) increases the risk of adverse cardiovascular outcomes. However, the causal relationships between renal function and cardiovascular diseases (CVD) remain incompletely understood. This study aimed to determine the causal relationships between genetic susceptibility to impaired renal function and the risk of CVD endpoints, as well as cardiac structure and function detectable by cardiac magnetic resonance imaging (CMR).
Methods: Bidirectional Mendelian randomization (MR) analyses were conducted using summary-level data from genome-wide association studies. The exposures were blood urea nitrogen (BUN), estimated glomerular filtration rate (eGFR), urine albumin-to-creatinine ratio (UACR), and CKD. The outcomes included atrial fibrillation, coronary artery disease (CAD), myocardial infarction, heart failure, stroke, and various CMR parameters. Sensitivity analyses, multivariable MR adjusting for cardiometabolic traits, and replication in the FinnGen cohort were performed.
Results: Elevated BUN levels (OR 1.505; 95% CI 1.077 to 2.103; P = 0.017) were causally associated with increased CAD risk, but this relationship was attenuated after adjusting for cardiometabolic traits. Increased UACR was causally linked to higher risks of CAD (OR 1.260; 95% CI 1.042 to 1.523; P = 0.017), myocardial infarction (OR 1.424; 95% CI 1.137 to 1.783; P = 0.002), and stroke (OR 1.182; 95% CI 1.012 to 1.379; P = 0.035), with the association for stroke remaining significant after multivariable adjustment. Reduced eGFR was causally related to decreases in ascending aorta diameter, proximal pulmonary artery diameter, right atrial size, left ventricular stroke volume, and right ventricular volumes, even after accounting for potential confounders. CKD was causally associated with a reduced pulmonary artery-to-aorta ratio and proximal pulmonary artery diameter.
Conclusions: This comprehensive MR study establishes causal roles of genetic susceptibility to impaired renal function influencing cardiovascular outcomes and cardiac structure.

State of Indigenous Peoples', Local Communities', and Afro-descendant Peoples' Carbon Rights in Tropical and Subtropical Lands and Forests
Authors:   Rights and Resources Initiative,   McGill University
Published: November 2024

This brief summarizes findings from a study undertaken by the Rights and Resources Initiative and McGill University to systematically analyze the carbon rights held by Indigenous Peoples, local communities, and Afro-descendant Peoples in 33 countries in Africa (11), Asia (9), and Latin America (13) that cover over 35% of the world’s forest. We examine whether and how countries protect the rights necessary for communities to manage, control, and benefit from carbon on their lands and to access compensation and justice when they are affected by carbon trading initiatives. We collected data on 35 indicators from domestic laws and policies related to land, carbon, and resource rights across several sectors, including constitutional law; land tenure administration; and forest, climate, and environmental law. Across these 33 countries, our analysis refers to the legal rules that govern 96 community-based tenure regimes (CBTRs) identified by RRI in these countries.
Online Health Services: Attitudes and Behaviors among Adults in Israel
Authors: Reicher Sima , Madar Galit , Toren Orly
Published: November 2024

Objective: Online Health Services (OHS) emerged in the last decade and currently encompass technologies that facilitate patient-practitioner communication in medical fields such as diagnosis, treatment, counseling, and monitoring, including for chronic patients. The current study aims to describe attitudes and behaviors related to OHS and identify variables that explain online technology use. Methods: A descriptive cross-sectional study among Hebrew-speaking, computer-literate adults, with data collected via online questionnaires. The convenience sample included 700 respondents, of whom 57.4% were female. Respondents’ mean age was 64 years, with most being married (59.3%), secular (75.9%), academically educated at the undergraduate, graduate and postgraduate levels (59.1%), and having a chronic illness (65.7%). Results: Despite high OHS use among nearly half the participants, most were undecided whether they preferred in-person or online treatment. Preference for in-person treatment was negatively associated with the perceived efficiency and safety of online treatment, online health literacy, and the extent of OHS use. Key variables explaining OHS use were perceived efficiency and safety of online treatment, online health literacy, preference for in-person treatment, and chronic illness. The explained variation of the OHS consumption model was 40.4%. Conclusion: The variables explaining OHS use are not necessarily linked to classic background variables, e.g. gender, age, and education, but rather to variables related to the use of OHS for therapeutic purposes. OHS are not perceived as substitutes for in-person meetings with healthcare providers but as a supplementary service. Therefore, to enhance OHS use rates, decision-makers should improve online health literacy and design services integrating OHS with in-person treatment.

Published: November 2024

Economic dispatch (ED) aims to identify the most cost-effective strategy for allocating power generation while meeting demand and adhering to the physical constraints of the power system. In this paper, three algorithms are proposed to solve the ED problem in power systems, including a hybrid Particle Swarm Optimization with Grey Wolf Optimizer (PSO-GWO), modified Velocity Aided Grey Wolf Optimizer (VAGWO), and Grey Wolf Optimizer (GWO). PSO is a meta-heuristic optimization technique designed to find the optimal solution to a problem by guiding the movement of particles within a defined exploration space. GWO is also a meta-heuristic optimization algorithm based on the natural behavior of grey wolves. In this paper, to enhance the performance of GWO, it is first combined with the PSO method. VAGWO is employed to refine the GWO formulation by optimizing the convergence steps. At the beginning of the iterations, the distance between the solutions (wolves) is increased to promote exploration of the search space. As the iterations progress, the step size is reduced, allowing for a more precise and efficient convergence toward the optimal solution. These algorithms will be implemented in Matlab software to minimize the fuel cost production of the following test networks: IEEE 30-bus network, Algerian 114-bus network, and Southeast Algerian network. These methods show that the PSO-GWO algorithm offers better results when compared through VAGWO and GWO.

This paper presents two robust controls techniques: current control in the dq reference frame and direct power control (DPC) applied to a three-phase PWM rectifier to achieve efficient dc voltage regulation, unit power factor control and harmonic distortion rate reduction. Simulations were performed using Matlab/Simulink software. According to these results, the DPC direct power control seems to be more efficient than the current control in the dq reference frame, which has a lower harmonic distortion rate, and the DC voltage follows its new reference for the two developed controls. However, the response time, overshoot and oscillations of the controlled quantities, as well as the exponential convergence of the errors for the transient regime and the setpoint change, are different. It can be seen that the best values of the latter are those obtained by applying the DPC direct power control, which is considered to be the best performing and most efficient control compared to the other control.

Exponential probability inequalities play an important role in many parts of probability and statistics, offering a fundamental tool for tail probability bounding and modeling stochastic processes. The present work proposes a new exponential inequality for acceptable random variables. This class covers dependencies that are not embraced by the standard independence assumptions. Our results extend the theoretical perspective by placing sharper bounds on the above-mentioned variables, which tends to increase the accuracy of probabilistic modeling. Moreover, we study complete convergence in first-order autoregressive processes with acceptable innovations. The complete convergence framework gives further insights into the long-term behavior of the wide class of processes commonly used in time series analysis, econometrics, and other areas of applied research. In turn, our results on the influence of acceptable innovations on the properties of complete convergence establish bridges between theoretical probability inequalities and statistical applications. In addition, these contributions provide new tools in investigating the stability and predictability of the autoregressive models. These considerations consequently set up significant perspectives and enrich a developing body of research related to stochastic processes by reinforcing the theoretical framework as well as the methodological apparatus of probability theory.

Sustainable development is a contemporary concern in the field of asphalt pavements, as road construction consumes a significant amount of new aggregates. Furthermore, road maintenance necessitates the milling of old pavement layers, which generates a substantial quantity of bituminous material waste. This study explores the use of recycled sand from asphalt waste as a substitute for 0, 25, 50, 75, and 100% of natural sand in self-compacting mortar, aiming to achieve both sustainable and economical asphalt production. The differences in physical properties between natural sand (NS) and fine recycled asphalt pavement (FRAP) aggregates are analyzed and compared. The characteristics of the various self-compacting mortars are measured, including spread, flow time, as well as compressive and tensile strength, shrinkage and sorptivity. Compared to the control mortar, the mortars containing RPAS exhibit a rougher surface, additional pores, and more complex pore structures. The need for superplasticizers increases with the substitution rate, as do the rheological parameters. The results indicate that recycled mortar can be an alternative to natural sand, although this comes with negative impacts on the mechanical properties of the mortar. Nonetheless, these effects can be mitigated when considering their economic and environmental implications.

Os microRNAs (miRNAs) são pequenos fragmentos de RNA que desempenham um papel vital na regulação da expressão gênica e estão envolvidos em diversos processos biológicos, incluindo o desenvolvimento de doenças neurodegenerativas. Eles atuam ligando-se a moléculas de RNA mensageiro (mRNA), resultando na inibição da produção de proteínas e, consequentemente, afetando a função celular. Pesquisas recentes associam a desregulação dos miRNAs a doenças como Alzheimer e Parkinson, dentre outras, evidenciando sua importância na patologia dessas condições. Este trabalho de revisão de literatura explora a biogênese dos miRNAs, detalha seus mecanismos de ação e examina seu papel na regulação gênica. Além disso, discute a inter-relação entre a metilação do DNA e a expressão dos miRNAs, indicando que alterações epigenéticas podem influenciar a atividade desses reguladores. Os miRNAs se destacam como potenciais biomarcadores, podendo auxiliar no diagnóstico precoce e na monitorização de doenças neurodegenerativas. Também são considerados alvos terapêuticos promissores, sugerindo que a manipulação de suas vias de sinalização pode levar ao desenvolvimento de tratamentos mais eficazes. Portanto, os miRNAs emergem como moléculas-chave na compreensão dos mecanismos subjacentes a essas doenças, abrindo novas perspectivas para intervenções terapêuticas inovadoras e personalizadas, visando não apenas a mitigação dos sintomas, mas também a modulação dos processos patológicos envolvidos nas doenças neurodegenerativas.

Published: November 2024

Blasting operations in mines near communities are of increasing social concern and scientific investigation due to the potential structural damage and human discomfort caused by blasting induced vibrations. Therefore, a technical-scientific approach is necessary to conduct these activities safely and sustainably compatible with fragmentation requirements of the scale of production. This paper presents a case study of an open-pit mine located in Brazil, where blasts are frequently carried out near a community. Additionally, controlling flyrock is extremely important in this mine due to the proximity of people to the blasting sites, as well as controlling the slope damage. Thus, it became necessary to develop a methodology for the application and combination of techniques and simulation fo blasting-induced vibration and wall control, flyrock and fragmentation such as attenuation law, signature holes, decking charge techniques, pre-split holes. The proposed methodology was effective, validated, and is recommended for open-pit mines operating near communities.
