The WRKY gene family plays a very diverse role in plant growth and development. These genes contained an evolutionarily conserved WRKY DNA binding domain, which shows functional diversity and extensive expansion of the gene family. In this study, we conducted a genome-wide comparative analysis to investigate the evolutionary aspects of the WRKY gene family across various plant species and revealed significant expansion and diversification ranging from aquatic green algae to terrestrial plants. Phylogeny reconstruction of WRKY genes was performed using the Maximum Likelihood (ML) method; the genes were grouped into seven different clades and further classified into algae, bryophytes, pteridophytes, dicotyledons, and monocotyledons subgroups. Furthermore, duplication analysis showed that the increase in the number of WRKY genes in higher plant species was primarily due to tandem and segmental duplication under purifying selection. In addition, the selection pressures of different subfamilies of the WRKY gene were investigated using different strategies (classical and Bayesian maximum likelihood methods (Data monkey/PAML)). The average dN/dS for each group are less than one, indicating purifying selection. Our comparative genomic analysis provides the basis for future functional analysis, understanding the role of gene duplication in gene family expansion, and selection pressure analysis.
Accurate temperature control during the induction heating process of carbon fiber reinforced polymer (CFRP) is crucial for the curing effect of the material. This paper first builds a finite element model of induction heating, which combines the actual fiber structure and resin matrix, and systematically analyzes the heating mechanism and temperature field distribution of CFRP during the heating process. Based on the temperature distribution and variation observed in the material heating process, a PID control method optimized by the sparrow search algorithm is proposed, which effectively reduces the temperature overshoot and improves the response speed. The experiment verifies the effectiveness of the algorithm in controlling the temperature of the CFRP plate during the induction heating process. This study provides an effective control strategy and research method to improve the accuracy of temperature control in the induction heating process of CFRP, which helps to improve the results in this field.
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.
The study of authoritarian leadership has undergone significant development, with researchers exploring its different dimensions and consequences. This leadership style, characterized by a top-down approach and centralized decision-making authority, has been extensively examined in psychology, organizational behavior, and management literature. Scholars have delved into the effects of authoritarian leadership on various aspects of organizations such as employee satisfaction, motivation levels, productivity rates, turnover rates, and team dynamics. The research landscape surrounding authoritarian leadership has witnessed a recent surge in interest as scholars strive to understand its intricate connections with different variables. The primary objective of this study is to conduct a comprehensive bibliometric analysis on authoritarian leadership, aiming to identify the key research areas, influential authors, prominent journals in the field, and citation patterns. To our knowledge, no bibliometric analysis on authoritarian leadership can be found in the Scopus database, highlighting the novelty of our research. Through a source-based examination of scholarly articles and their citations pertaining to authoritarian leadership, this analysis offers valuable insights into the current state of research in this domain. By focusing on publications from the past decade onwards, we aim to uncover trends and potential gaps within existing literature while also providing guidance for future research endeavors. Our research findings will provide valuable insights into the phenomenon of authoritarian leadership, contributing to a deeper understanding of its implications. By delving into this topic, we hope to pave the way for future studies and investigations in this field that can build upon our findings and expand knowledge even further.
This study explores the scale efficiency of four star hotels in a small tourist destination in Croatia. The number of overnight stays and the increase in hotel beds are two indicators of the development of a tourist destination. Among the accommodation facilities, hotels play a significant role in the development of a tourist destination, but they are increasingly facing a labor force crisis. Data envelopment analysis is used to rank hotels by efficiency coefficient. The aim of the paper is to investigate the efficiency of the hotel by taking certain inputs and outputs, which are explained in detail in the paper. The paper uses the CCR (Charnes, Cooper, and Rhodes) and BCC (Banker, Charnes, and Cooper) models to calculate hotel scale efficiency and also presents an overview of previous research around the world.
