Cities play a key role in achieving the climate-neutral supply of heating and cooling. This paper compares the policy frameworks as well as practical implementation of smart heating and cooling in six cities: Munich, Dresden and Bad Nauheim in Germany; and Jinan, Chengdu and Haiyan in China, to explore strategies to enhance policy support, financial mechanisms, and consumer engagement, ultimately aiming to facilitate the transition to climate-neutral heating and cooling systems. The study is divided into three parts: (i) an examination of smart heating and cooling policy frameworks in Germany and China over the past few years; (ii) an analysis of heating and cooling strategies in the six case study cities within the context of smart energy systems; and (iii) an exploration of the practical solutions adopted by these cities as part of their smart energy transition initiatives. The findings reveal differences between the two countries in the strategies and regulations adopted by municipal governments as well as variations within each country. The policy frameworks and priorities set by city governments can greatly influence the development and implementation of smart heating and cooling systems. The study found that all six cities are actively engaged in pioneering innovative heating and cooling projects which utilise diverse energy sources such as geothermal, biomass, solar, waste heat and nuclear energy. Even the smaller cities were seen to be making considerable progress in the adoption of smart solutions.

This study, through the method of canonical correlation analysis, revealed significant correlations between various dimensions of learning attitudes of students and various dimensions of teacher knowledge. An analysis of data from a group of 221 high school students showed that teacher knowledge of teaching content, theoretical knowledge, and teaching practice and classroom management significantly impact learning attitudes of students. Specifically, teacher knowledge of teaching content plays a crucial role in promoting students' behavioral inclination to learn chemistry, teachers' theoretical knowledge significantly enhances students' liking for chemistry laboratory courses, while teachers' teaching practice and classroom management have a suppressive effect on students' evaluative beliefs about school chemistry. The results of this study provide effective guidance for both the theory and practice of high school chemistry education.

This paper presents a coupling of the Monte Carlo method with computational fluid dynamics (CFD) to analyze the flow channel design of an irradiated target through numerical simulations. A novel series flow channel configuration is proposed, which effectively facilitates the removal of heat generated by high-power irradiation from the target without necessitating an increase in the cooling water flow rate. The research assesses the performance of both parallel and serial cooling channels within the target, revealing that, when subjected to equivalent cooling water flow rates, the maximum temperature observed in the target employing the serial channel configuration is lower. This reduction in temperature is ascribed to the accelerated flow of cooling water within the serial channel, which subsequently elevates both the Reynolds number and the Nusselt number, leading to enhanced heat transfer efficiency. Furthermore, the maximum temperature is observed to occur further downstream, thereby circumventing areas of peak heat generation. This phenomenon arises because the cooling water traverses the target plates with the highest internal heat generation at a lower temperature when the flow channels are arranged in series, optimizing the cooling effect on these targets. However, it is crucial to note that the pressure loss associated with the serial structure is two orders of magnitude greater than that of the parallel structure, necessitating increased pump power and imposing stricter requirements on the target container and cooling water pipeline. These findings can serve as a reference for the design of the cooling channels in the target station system, particularly in light of the anticipated increase in beam power during the second phase of the China Spallation Neutron Source (CSNS Ⅱ).

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.

Consumer satisfaction can be defined as the user’s response to a service or experience compared to the user’s expectations and perceived practical benefits. After reviewing consumer satisfaction models, it can be argued that there is no single model of consumer satisfaction assessment that is suitable for every service and every region of the world, as the causes and outcomes of satisfaction often vary. The research is original in its methodology: at the beginning, a theoretical research model is presented, then hypotheses are formulated, and correlation, factorial, regression analyses were made, which results confirmed hypotheses. The crop insurance system consists of relations between the state institution regulates insurance activities, farmers, insurers and insurance intermediaries. The aim of this article is to identify the factors that determine consumer satisfaction with crop insurance and to assess their impact. The empirical study found that consumer satisfaction is determined by the factors of recognizable value, functional (process) and technical (result) quality, consumer expectations, and image. The most important factors that determine consumer satisfaction of crop insurance are recognizable value, functional quality, and consumer expectations. Consumer satisfaction can be assessed by the cost paid and the quality received, the quality expected, and the consumers’ evaluation of the services. It was found that the socio-demographic elements of consumers do not have a decisive influence on the factors that determine service satisfaction and consumer satisfaction. It is also established that socio-demographic elements of consumers (farmer experience and insurance experience) have direct statistically significant but weak links with consumer satisfaction.
