Inequity in infrastructure distribution and social injustice’s effects on Ethiopia’s efforts to build a democratic society are examined in this essay. By ensuring fair access to infrastructure, justice, and economic opportunity, those who strive for social justice aim to redistribute resources in order to increase the well-being of individuals, communities, and the nine regional states. The effects that social inequity and injustice of access to infrastructure have on Ethiopia’s efforts to develop a democratic society were the focus of the study. Time series analysis using principal component analysis (PCA) and composite infrastructure index (CII), as well as structural equation modeling–partial least squares (SEM-PLS), were necessary to investigate this issue scientifically. This study also used in-depth interviews and focus group discussions to support the quantitative approach. The research study finds that public infrastructure investments have failed or have been disrupted, negatively impacting state- and nation-building processes of Ethiopia. The findings of this research also offer theories of coordination, equity, and infrastructure equity that would enable equitable infrastructure access as a just and significant component of nation-building processes using democratic federalism. Furthermore, this contributes to both knowledge and methodology. As a result, indigenous state capability is required to assure infrastructure equity and social justice, as well as to implement the state-nation nested set of policies that should almost always be a precondition for effective state- and nation-building processes across Ethiopia’s regional states.

The direct expansion heat pump with solar energy is an energy conversion system used for water heating applications, air heating for air conditioning buildings, water desalination, solar drying, among others. This paper reviews the main designs and analysis of experiments in order to identify the fundamental objectives of any experiment which may be: to determine the factors that have a significant influence, to obtain a mathematical model and/or to optimize performance. To achieve this task, the basic and advanced configuration of this system is described in detail in order to characterize its thermal performance by means of energy analysis and/or exergy-based analysis. This review identifies possible lines of research in the area of design and analysis of experiments to develop this water heating technology for industrial applications.

The practice of ethical management has gained traction due to its role in enhancing stakeholder relations, which can have severe repercussions for organisations. By prioritising ethics, companies not only uphold moral principles but also gain a competitive advantage. This is particularly true in societies that value socially responsible business and give preference to companies that go beyond the requirements of the law. Understanding the significance of ethical management practices is therefore becoming key to creating a responsible and sustainable business environment that benefits both an organisation and its stakeholders, such as employees, consumers and society. The purpose of this article is to present a comprehensive exploration of the impact of selected aspects of ethical management in Slovak companies with foreign participation on the ethicality of their relationships with stakeholders. By examining a range of factors related to ethical management, the article seeks to identify statistically significant differences among companies with different approaches to managing business ethics. Employing this analysis, the article contributes to the understanding of ethical practices in Slovak companies and provides insights for academics and practitioners of business ethics. The data used for this analysis was collected through an online questionnaire survey, resulting in a sample size of 179 monitored subjects, all of whom are Slovak companies with foreign participation. The research design included two groups of factors: “general factors of business ethics” or “ethical management approaches” and “ethicality of company-stakeholder relationships.” The statistical analysis included the Shapiro-Wilk normality test, followed by the non-parametric Kruskal-Wallis H test, and post hoc analysis using the Bonferroni adjustment for previously identified significances. The results of the research presented in the article indicate a predominantly positive ethical stance towards employees, suppliers, customers and other stakeholders among Slovak companies. Statistically significant differences were found in the levels of ethicality in relation to legal form, with limited liability and joint-stock companies showing different perceptions towards supplier ethics. The research also proves that an ethical organisational climate is a major determinant of the ethicality of Slovak companies and suggests that a robust integration of ethics into strategic planning significantly improves their stakeholder relations. It can also be concluded that the scope of a code of ethics is particularly significant for community relations, whereas the frequency with which it is updated has less impact. This research holds significant value because it explores the impact of ethical management practices on stakeholder relations and ethical issues in Slovak companies with foreign participation. By focusing on the specific context of Slovak companies, the research offers unique insights into the relationship between ethical management factors and stakeholder dynamics. This research aims to bridge a gap by shedding light on the intricate dynamics between ethical management and stakeholder relations. The findings provide valuable guidance to organisational leaders, policymakers and stakeholders in fostering ethical behaviour and mitigating ethical risks within companies.

This study explores how demographic factors shape perceptions of celebrity and influencer marketing in the context of promoting cryptocurrencies, particularly in the tourism sector. It evaluates whether such marketing strategies effectively promote cryptocurrencies and how their impact varies across demographic groups. By analyzing responses from a sample of 161 predominantly young and educated respondents, the study uses statistical methods to identify differences in perceived marketing effectiveness based on age, gender, and other demographics. Findings reveal no significant demographic differences in effectiveness; instead, the study underscores the importance of universal marketing qualities, such as authenticity, credibility, and relevance. These results suggest the need for inclusive marketing strategies that foster trust and transparency. Additionally, the study highlights avenues for future research, including cultural and ethical considerations, to refine marketing approaches and develop innovative campaigns that drive cryptocurrency adoption and trust in the tourism industry.

Road accidents involving motorcyclists significantly threaten sustainable mobility and community safety, necessitating a comprehensive examination of contributing factors. This study investigates the behavioral aspects of motorcyclists, including riding anger, sensation-seeking, and mindfulness, which play crucial roles in road accidents. The study employed structural equation modeling to analyze the data, utilizing a cross-sectional design and self-administered questionnaires. The results indicate that riding anger and sensation-seeking tendencies have a direct impact on the likelihood of road accidents, while mindfulness mitigates these effects. Specifically, mindfulness partially mediates the relationships between riding anger and road accident proneness, as well as between sensation-seeking and road accident proneness. These findings underscore the importance of effective anger management, addressing sensation-seeking tendencies, and promoting mindfulness practices among motorcyclists to enhance road safety and sustainable mobility. The insights gained from this research are invaluable for relevant agencies and stakeholders striving to reduce motorcycle-related accidents and foster sustainable communities through targeted interventions and educational programs.

Color visually communicates the product’s flavors to consumers and further influences their taste perception. This study explores the perceived taste of tea beverages caused by the logo’s principal colors, using hand-shaken tea beverages in Taiwan as an example. To identify the linkage between the logo color and tea tastes, this study divides the taste of tea beverages into four categories: sweetness, freshness, bitterness, and astringency. Then, the 69 tea beverage logos are allocated into the 14 color sections in the CIELAB color space according to their primary colors. The Correspondence Analysis method is employed to visualize the relationships between the logos and the perceived tastes. The tea tastes are then mapped into the color sections in the CIELAB color space. The analysis results reveal that the sweetness links to logos in the Warm Scheme colors (hue angle from 0 to 59 degrees). The fresh taste is bound with the logo with the Cool White Scheme colors (hue angle from 90 to 149 degrees and brightness >80). Finally, the bitter and astringent tastes link to the logo colors in the Cold Black Scheme colors (hue angle from 60 to 89 degrees, 150 to 329 degrees, and brightness <25). This study expands the color and taste association literature from general food to tea beverages. Our obtained empirical results can be applied to hand-shaken beverage companies to select principal colors for designing logos and packages that align with tea beverages’ perceived tastes to convey brand recognition accurately.
