This study aims to determine the effects of monosodium glutamate (MSG) dosage on the yield of long beans (Vigna sinensis L.) of the Peleton variety. The use of MSG as a food ingredient has been a topic of debate, but research on its impact on plant growth is still limited, especially regarding long beans. Therefore, this research is important for providing further understanding of the influence of MSG on long beans plants. The study was conducted from July to October 2023 in Mata Air Village, Central Kupang District, Kupang Regency, East Nusa Tenggara Province. The research method used was a Randomized Complete Block Design (RCBD) with 9 treatments and 3 replications. The treatments included: No MSG, MSG at doses of 2.5 g/plant, 5 g/plant, 7.5 g/plant, 10 g/plant, 12.5 g/plant, 15 g/plant, 17.5 g/plant, and 20 g/plant. Parameters observed included flowering age (days), number of pods (pieces), pod length (cm), and pod weight (g). Based on the results and discussion, it can be concluded that MSG application had a significant effect on the number, length, and weight of pods, but had a non-significant effect on flowering age. The treatment of 15 g/plant was identified as the optimal MSG dosage for the plants, resulting in the highest number of pods (16.2), longest pod length (60.4 cm), and highest pod weight (256.4 g/plant). This research is innovative in exploring the potential use of monosodium glutamate (MSG) on long beans plants, particularly the Peleton variety. The focus on MSG application as a growth stimulant is an innovative step that has been less studied previously. The discovery of the optimal MSG dosage (15 g/plant) for achieving the best results provides valuable information for farmers to enhance productivity efficiently, sustainably, and environmentally friendly. Information about MSG’s potential as a plant stimulant can serve as a starting point for more sustainable agricultural strategies aimed at optimizing available resources.

The article discusses the essence of integrative geography and its importance for the theory and practice of geographical science. Such areas of integrative geography are characterized, the development of which will further increase the importance of applied geographical science. They include teaching about cultural landscape and historical landscape (part of landscape studies), geoecological expertise and environmental impact assessment (part of geographic ecology), geographic archeology and ecological culture (part of historical geography), landscape management and landscape services (part of landscape planning), and tourism—Assessment and planning of recreational resources (part of recreational geography).

The chemical reinforcement of sandy soils is usually carried out to improve their properties and meet specific engineering requirements. Nevertheless, conventional reinforcement agents are often expensive; the process is energy-intensive and causes serious environmental issues. Therefore, developing a cost-effective, room-temperature-based method that uses recyclable chemicals is necessary. In the current study, poly (styrene-co-methyl methacrylate) (PS-PMMA) is used as a stabilizer to reinforce sandy soil. The copolymer-reinforced sand samples were prepared using the one-step bulk polymerization method at room temperature. The mechanical strength of the copolymer-reinforced sand samples depends on the ratio of the PS-PMMA copolymer to the sand. The higher the copolymer-to-sand ratio, the higher the sample’s compressive strength. The sand (70 wt.%)-PS-PMMA (30 wt.%) sample exhibited the highest compressive strength of 1900 psi. The copolymer matrix enwraps the sand particles to form a stable structure with high compressive strengths.

In this paper, we explore the static and dynamic effects of oil rent on competitiveness in Saudi Arabia’s economy during the period 1970–2022. In addition, we examined the short-run, strong and long-run relationships between exports and industry, inflation, energy use (oil rents) and agriculture using the Autoregressive Distributed Lag (ARDL) approach developed. The analysis showed that government spending will contribute to enhancing the competitive environment with a difference of one year. Moreover, the industry will contribute to increasing competitiveness for a positive relationship in the long term. The results stated that there is an insignificant relationship between competitiveness, inflation, and oil rents. The analysis also shows that inflation has a negative impact with statistical significance in the short term. In addition, the error correction model (ECM) coefficient is negative and has statistical significance at 0.76 at a 1% significant level, which indicates the existence of an error correction mechanism and thus the existence of a long-term relationship between the variables.

 The main goal of the article is to formalize the key business models of marketing of modern companies and substantiate the key stages, types and trends of development. The relevance and need to pay significant attention to the marketing digital business model when organizing a business is substantiated. Using structural and logical analysis and criticism of scientific research, the essence, advantages and disadvantages are determined, the main blocks, stages and key elements of the structure of business models of modern companies are argued. It has been proven that marketing digital business models serve as a logical and visual plan for organizing all business processes of companies from production, marketing, sales and logistics to building a hierarchy of profitability. The key development trends are substantiated and the most popular business models of business organization in modern conditions are structured on the basis of scientific generalization, structural and logical analysis and mathematical modeling. Practical significance is characterized by the fact that the marketing business models of world-class companies are generalized and structured, taking into account their specifics and characteristics. Practical recommendations and key stages of building a company’s business model and its implementation into reality have been formed to achieve strategic business goals.

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.
