In the era of globalization and advanced information transparency, competition between companies has become increasingly fierce due to the large number of products and services that have similar characteristics. This situation creates a competitive and dynamic business climate, where companies must adapt quickly to the changes that occur. This study investigates the impact of servant leadership on employee performance at Mandiri In health, focusing on employee engagement and Organizational Citizenship Behavior as relevant mediating variables. The study used a proportionate stratified random sampling method to determine the sample of respondents, which ultimately consisted of 206 individuals who were analyzed using Structural Equation Modeling (SEM) techniques. The main findings of the study show that servant leadership has a significant direct influence on employee performance, employee engagement, and Organizational Citizenship Behavior in the company. This indicates that service-oriented leadership practices not only influence individual performance, but also contribute to employee volunteering and active engagement in the organization. Employee engagement and Organizational Citizenship Behavior affect employee performance directly, there is no evidence that servant leadership affects employee performance indirectly through the mediation of employee engagement. There is an indication that Organizational Citizenship Behavior acts as a mediator between servant leadership and employee performance, indicating the importance of organizational citizenship behavior in facilitating the positive relationship between leadership and performance. These findings provide a deeper understanding of how leadership strategies can significantly contribute to the achievement of organizational goals in a competitive business environment.

In the perspective of this article, the intercultural influences are viewed through the lens of educational benefits likely to be acquired by students following international socio-educational exchange programs. A model analysis is proposed based on these benefits on students majoring in economic areas, and it has been based on the perspective of influences through education and interaction with different cultures as compared to those of which the individual belongs to, respectively social influence. The research carried out was based on the observations made throughout a five-year period, between 2013 and 2018, regarding the evolution of students participating in the Erasmus programs. The analysis of the international socio-educational experience of people who studied abroad at a foreign university for a certain period of time was the starting point to design a research methodology so that the proposed topic could be investigated by collecting, structuring and analysing qualitative data, considering the fact that qualitative data will allow the discovery of associations of features, respectively of the benefits of personal experiences, which can only be analysed and perceived through the lens of points of view of those who experienced them. The qualitative research included the analysis of students in economics majors participating in the Erasmus program during the academic year 2018–2019 at a small university. The interview technique was used and the processing and interpretation of the data was carried out using software specific to qualitative research. The analysis carried out focused on the identification of complex connections underlying in the answers received from the respondents, answers that allowed the outlining of conceptual maps related to the research objectives. The purpose of the analysis was to underline the intercultural influences as perceived throughout four processes: individual internalization, socialization, individualization and humanization. These influences are revealed by the outcome of the research, that is the five conceptual maps that have resulted. These conceptual maps represent a starting point for future similar researches.

We studied Zeta potentials of nanoparticles titanium dioxides （nTiO₂） in different concentration of NaNO₃ and phosphate (P) solutions. In addition, the effect of flow rate on the transport of nTiO₂ in P was investigated at pH＝6.5. Experimental results show that the Zeta potential of nTiO₂ is compressed with the increasing ion concentration (IC) of NaNO₃ at pH＝6.5. The negative charge increases with the augment of P. Therefore, the high P and low NaNO3 induce the stabilization of nTiO₂ aggregates. The transport experiments suggest that the rapid flow rate is favorable for the transportability of nTiO₂ and soluble phosphate. The breakthrough transport curves (BTCs) of nTiO₂ in sand columns can be fitted well with two-site kinetic attachment model. The modeling results suggest that the values of first-order attachment rate coefficients (k₂) and detachment rate coefficients (k_2d) on site 2 and first-order attachment rate coefficients (k₁) on site 1 are responsible to the attaching efficiency of nTiO₂ on sands and their transportability.

Agriculture is a determining factor regarding the development of the Romanian economy, noting its importance for population consumption and as a supplier of raw materials for the relaunch of other industries. Agricultural financing consists of credits granted to natural or legal persons for developing agricultural activities, expanding agricultural holdings, and commercializing agricultural production. The objective of this research is the statistical analysis of the determining factors in granting loans to Romanian farms. The study is based on the content analysis of the accounting reports of the 45 Romanian farms included in the research sample, based on which the profile of the farmer from the selected counties (Alba, Cluj, Mures, Sibiu, Dambovita and Prahova) is outlined. The obtained results highlight the fact that factors such as the requested amount (SUSO) are directly influenced by the worked area (TELU), by the turnover (CIAF), R = 0.6228, but also by the total value of the assets (TOTAL) R = 0.454. At the opposite pole, there is a weak correlation between SUSO and current liquidity (LICU), R = 0.2754, and the value of recorded expenses (CHEL), R = 0.3102. Implementing a credit policy that facilitates access to financing sources would support farms in modernization and development, increasing their competitiveness and general viability.

In this Data science research on Education, it analyses the alcohol consumption, parent’s education, study time and other factors may influence on student performance.

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.
