This study aims to analyze the factors, evaluation techniques of the durability of existing railway engineering.

China has built a railway network of over 150,000 km. Ensuring the safety of the existing railway engineering is of great significance for maintaining normal railway operation order. However, railway engineering is a strip structure that crosses multiple complex environments. And railway engineering will withstand high-frequency impact loads from trains. The above factors have led to differences in the deterioration characteristics and maintenance strategies of railway engineering compared to conventional concrete structures. Therefore, it is very important to analyze the key factors that affect the durability of railway structures and propose technologies for durability evaluation.

The factors that affect the durability and reliability of railway engineering are mainly divided into three categories: material factors, environmental factors and load factors. Among them, material factors also include influencing factors, such as raw materials, mix proportions and so on. Environmental factors vary depending on the service environment of railway engineering, and the durability and deterioration of concrete have different failure mechanisms. Load factors include static load and train dynamic load. The on-site rapid detection methods for five common diseases in railway engineering are also proposed in this paper. These methods can quickly evaluate the durability of existing railway engineering concrete.

The research can provide some new evaluation techniques and methods for the durability of existing railway engineering.

Lubricating oil leakage is a common issue in thermal power plant operation sites, requiring prompt equipment maintenance. The real-time detection of leakage occurrences could avoid disruptive consequences caused by the lack of timely maintenance. Currently, inspection operations are mostly carried out manually, resulting in time-consuming processes prone to health and safety hazards. To overcome such issues, this paper proposes a machine vision-based inspection system aimed at automating the oil leakage detection for improving the maintenance procedures.

The approach aims at developing a novel modular-structured automatic inspection system. The image acquisition module collects digital images along a predefined inspection path using a dual-light (i.e. ultraviolet and blue light) illumination system, deploying the fluorescence of the lubricating oil while suppressing unwanted background noise. The image processing module is designed to detect the oil leakage within the digital images minimizing detection errors. A case study is reported to validate the industrial suitability of the proposed inspection system.

On-site experimental results demonstrate the capabilities to complete the automatic inspection procedures of the tested industrial equipment by achieving an oil leakage detection accuracy up to 99.13%.

The proposed inspection system can be adopted in industrial context to detect lubricant leakage ensuring the equipment and the operators safety.

The proposed inspection system adopts a computer vision approach, which deploys the combination of two separate sources of light, to boost the detection capabilities, enabling the application for a variety of particularly hard-to-inspect industrial contexts.

This paper investigates the consequences of job insecurity among hotel employees during the COVID-19 pandemic.

Data were obtained from the employees of two five-star chain hotels in Turkey. The study hypotheses were tested via structural equation modeling.

The research findings demonstrate that job insecurity exacerbates job tension. Job tension erodes employees’ trust in organization and aggravates their propensity to leave work early and be late for work. As hypothesized, job tension mediates the effect of job insecurity on organizational trust and the abovementioned outcomes.

This study adds to the hospitality literature by assessing the interrelationships of job insecurity, job tension, organizational trust and nonattendance intentions.

The overall objective of this study is envisaged to provide decision makers with actionable insights and access to multi-risk maps for the most in-danger stave churches (SCs) among the existing 28 churches at high spatial resolution to better understand, reduce and mitigate single- and multi-risk. In addition, the present contribution aims to provide decision makers with some information to face the exacerbation of the risk caused by the expected climate change.

Material and data collection started with the consultation of the available literature related to: (1) SCs' conservation status, (2) available methodologies suitable in multi-hazard approach and (3) vulnerability leading indicators to consider when dealing with the impact of natural hazards specifically on immovable cultural heritage.

The paper contributes to a better understanding of place-based vulnerability with local mapping dimension also considering future threats posed by climate change. The results highlight the danger at which the SCs of Røldal, in case of floods, and of Ringebu, Torpo and Øye, in case of landslide, may face and stress the urgency of increasing awareness and preparedness on these potential hazards.

The contribution for the first time aims to homogeneously collect and report all together existing spread information on architectural features, conservation status and geographical attributes for the whole group of SCs by accompanying this information with as much as possible complete 2D sections collection from existing drawings and novel 3D drawn sketches created for this contribution. Then the paper contributes to a better understanding of place-based vulnerability with local mapping dimension also considering future threats posed by climate change. Then it highlights the danger of floods and landslides at which the 28 SCs are subjected. Finally it reports how these risks will change under the ongoing impact of climate change.

This study aims to examine the latent capability of alternative-responsible tourism and ecotourism management in sustainable tourism and rural communities' livelihoods in Musina Municipality in Limpopo Province, South Africa, and benchmark the capability with other African countries amid climate change and environmental degradation dilemmas. Hence, the aforementioned objective coordinates with various agrarian locations elsewhere abroad.

Literature reviews, document reviews, interviews, and focus group discussions were employed to gather data, which was enriched by field observation views. To this end, potential climate change-linked environmental degradation, rural tourism, agricultural, and environmental management issues came to the fore.

Environmental degradation poses a possible threat to natural resource management, as evidenced by the rural development, ecotourism and agricultural activities within the study region. Thereupon, environmental degradation supplements the probability of adverse effects from climate change and precarious incomes. According to the research, responsible tourism and ecotourism are vital to promoting sustainability in rural localities.

The plenteous biodiversity of the municipality offers a better scenario for sustainable ecotourism in tandem with agritourism efforts to address the identified ongoing and liability issues. These issues have therefore symbolized the need for an adequate and allied tourism strategy to boost the local people in Musina Municipality and, conceivably, throughout the continent.

This paper aims to investigate sustainability-led innovation, focusing on the interplay between product and process innovation for sustainability goals and the underlying supplier–customer relationships. Thus, the paper delves into sustainability-led innovation and how it affects supplier–customer relationships, and vice versa, thus providing a twofold perspective.

The textile industry is the empirical context of this study, which is exploratory research based on in-depth, semi-structured interviews with entrepreneurs, managers and experts in the textile industry.

In the textile industry, sustainability-led product innovation concerns mainly product durability and performance, product recyclability and the use of waste for new product development. Process innovation deals with circular economy, traceability and water and chemical use minimization. The paper also shows how sustainability-led innovation is implemented in more technical terms and regarding supplier–customer relationships.

The paper adopts an original perspective on how processes take place in the relationships between suppliers and customers, where there is no dominance of one actor, but innovation emerges from interdependence and interaction. Such perspective allows to provide an in-depth analysis of the supplier–customer relationships and underlying dynamics that affect sustainability-led innovation; moreover, the authors study how such innovation impacts supplier–customer relationships and the underlying relational dynamics. The value of the paper also stands in delivering a real representation of the innovation processes grounded in the textile industry.

The purpose of this paper is to illustrate the opportunities for tobacco farmers in Malawi from diversifying to cannabis, and the potential benefits for reducing deforestation by producing a cannabis based alternative fuel. It further argues that there are tensions between the conflicting objectives of the Framework Convention on Tobacco Control and the Single Convention on Narcotic Drugs.

Field interviews were conducted with cannabis farmers, traders and sellers in different parts of Malawi.

The findings of this study show that there are opportunities for cannabis farmers but they have been blocked by legal impediments. Now that legislative reform have made cannabis cultivation possible, farmers need support in developing products.

Any attempt to provide a precise assessment of the cannabis market in Malawi is constrained by the criminalised status of the product. The suitability of cannabis briquettes as an fuel has yet to be trialled in Malawi.

There is an urgent need to revise the drug control conventions to address environmental degradation and deforestation.

The linkage between tobacco farming, deforestation and desertification in Malawi has not been made. This is the first time that hemp has been suggested as an alternative crop for farmers and as a solution to deforestation.

This paper aims to explore a single-institution case study of partnership working between students, the University and Students’ Union, through four student-led sustainability projects. The paper analyses the role and value of these partnerships and provides advice for other institutions on effective partnership working between these stakeholders.

A single case study of partnership working with multiple embedded units of analysis (four projects) is presented based on reflections of practitioners involved in the projects who have different roles within the University and Students’ Union.

The longevity and effectiveness of student-led projects, and disciplinary-breadth of students engaged, can be enhanced by greater collaboration with, and integration into, University and Students’ Union systems. Partnership working between different stakeholders is key to overcoming challenges and the success of student-led projects, helped by key staff “enablers”. These projects provide myriad learning opportunities for developing change agency skills, even where projects are relatively short-lived and could be seen as failures in terms of longevity.

This analysis is based solely on practitioner reflections, with limited direct quantification or qualitative data on the projects’ impacts on the students themselves.

This paper draws together the experiences and reflections of four practitioners with different roles within the University and Students’ Union across four different projects and provides advice to generate student-led sustainability projects which have longevity and impact for wider student populations and future generations of cohorts.

The purpose of this paper is to address notions and practices relating to work–life balance for native German scholars and researchers who have migrated from the former Soviet Union (FSU). Issues will be explored from a cultural perspective, identifying culturally based interpretations of work–life balance.

Foregrounded in a diversity approach, this empirical study draws upon explorative interviews to discuss work–life balance in German academia. To overcome monocultural observations, 25 German scholars and 11 researchers originating from the FSU were interviewed, all of whom are highly skilled female scholars.

Findings demonstrate that individuals with diverse cultural backgrounds can perceive huge differences in identical working conditions. The study links meanings of work–life balance with individual practices and identifies key components of work–life balance within this population. It also discusses the decisions that scholars make about starting families or remaining childless for the sake of their careers.

This study is the first of its kind in Germany, and represents a strong implication for policies and their evaluation. It identifies the crucial role played by culturally rooted notions relating to work–life balance practices.

Via the lens of the ego-depletion phenomenon (Baumeister et al., 1998) and Higgins' (1998) regulatory focus theory, this paper seeks to explain why current controlled communications are failing to achieve coherence between people's free will and their actions pursuing sustainable goals in a society. This paper explains how ego-depletion triggered by controlled communications can lead to confusion and decision fatigue in a society, thus potentially sabotaging people's participation in sustainable behaviour.

The authors applied Jaakkola's (2020) theory synthesis approach to integrate concepts from previously unconnected disciplines in order to generate novel insights in the area of controlled communication management.

The authors develop a theoretical framework and present research propositions that can help advance research and the discourse at the intersection of controlled communication and self-regulation theories.

This paper possesses the limitations associated with conceptual papers, e.g. the lack of empirical support of the study’s conceptual arguments.

This paper generates novel insights to assist communication practitioners and policymakers to improve vehicles and mechanisms of controlled communication with the public regarding sustainable goals pursuit.

To the best of authors' knowledge, this is one of the first papers that has merged the domains of self-regulation, ego-depletion, and controlled communication in an integrative framework in order to explain the mechanisms of how to enhance the effectiveness of controlled communication associated with sustainable goals pursuit.
