Reliability study plays a significant role in supporting the operation of any machinery working in a dynamic and harsh environment. This quality is inherently uncertain and a stochastic variable of any system. This study will be beneficial for designing an appropriate maintenance schedule, reducing unplanned production downtime and reducing maintenance cost of electrical motor operated particularly in dynamic and harsh environmental industries.

This study focused on the effects of operating conditions (OCs) on the operational reliability and remaining useful life (RUL) of machinery. A probabilistic graphical method called Bayesian network (BN) was used for studying the effect of OCs on the system performance. The developed methodology has been demonstrated by analyzing the operational reliability and predicting the RUL of electrical motors operated in a heavy mining machinery.

The failure probabilities estimated from the historical data of the motor system are failure likelihood, and OCs are the evidence in the developed BN model. It has been observed that the performance and RUL of the motor are significantly influenced by OCs and maintenance. A threshold value of reliability at which the motor system requires maintenance or replacement has been proposed to guide management in decision making.

The Bayesian approach for studying the covariate of motor reliability and RUL estimation is a novel approach. This study will be beneficial for designing an appropriate maintenance schedule, reducing unplanned production downtime and reducing maintenance cost of electrical motor operated particularly in dynamic and harsh environmental industries.

The study aims to investigate factors impacting consumers’ intention to adopt collaborative consumption (CC, hereafter) services. It extends the existing knowledge of CC services by testing and validating the moderating role of coercive power and the mediating role of attitude.

Applying random sampling, the data was collected through the mall intercept method across four cities in India and was analyzed using partial least square-structural equation modeling and artificial neural network to test the proposed hypotheses. A follow-up qualitative study consisting of 15 in-depth structured interviews helped validate the results of the quantitative research.

Results of the conducted survey revealed that a sense of community, reason-based trust and enjoyment positively impact consumers’ attitudes toward CC services. Attitude positively impacts intention and shows a partial mediating influence on the relationship between motivations and intentions. Furthermore, the results revealed the moderation of the perceived coercive power of the service provider. The results of the follow-up qualitative study validated the results of the quantitative research.

Managers of CC firms must understand the relative importance of intrinsic and extrinsic motivations in formulating the attitudes of consumers and intentions toward CC services. CC managers should acknowledge the influence of the consumer’s perceived coercive power of service providers and consumer’s reason-based trust.

To the best of the authors knowledge, the current research is the first of its kind. It has justifiably and logically applied self-determination theory and a slippery slope framework in a single context. By testing the moderating impact of coercive power, the research extends the existing literature on CC and the applicability of coercive power in CC. The present study extends the knowledge regarding the consumer’s perception of reason-based trust and the perceived coercive power of service providers in CC.

This study aims to explore how operational resilience can be achieved within supply ecosystems in the delicate yet harsh natural environments of the Arctic.

An in-depth, multiple qualitative case study of offshore supply operations in Arctic oil and gas field projects is conducted. Data from semi-structured interviews, personal observations and archival materials are analysed through institutional work and logics approaches.

The findings suggest that achieving social-ecological resilience depends on the interaction between social and natural (irreversible) systems, which are shaped and influenced by various institutional dynamics. Different resilience solutions were detected.

This study develops a comprehensive understanding of how social-ecological resilience emerges in supply ecosystems through institutional dynamics. The study’s empirical basis is limited to offshore oil and gas projects in the Arctic. However, due to anticipated future growth of Arctic economic activities, other types of supply ecosystems may benefit from the study’s results.

This research contributes with empirical knowledge about how social-ecological resilience is created through institutional interaction within supply ecosystems to prevent disruptions of both social and ecological ecosystems under the harsh natural conditions of the Arctic.

British Prime Minister, Rishi Sunak, recently introduced a “whole life order” sentence in response to sexually motivated or sadistic homicide offences (Gov.uk, 2023). Effectively, this condemns the recipient to the remainder of their life in incarceration and renders rehabilitative interventions redundant. The purpose of this paper is to explore the literature pertaining to public pedagogy, definitions and convictions, and rehabilitative interventions – all in relation to those considered to have committed sexuallymotivated or sadistic murders, with emphasis on the implications of such.

Through this commentary, this paper explores the following points in line with existing literature: (a) public knowledge of the criminal justice system and those who have committed homicide offences, (b) the manner of defining and convicting sexually motivated and sadistic murders and (c) current access to rehabilitation intervention programmes.

This paper closes by recommending future research initiatives to deliver forensic-specific education for the general public as well as qualitative studies into the discourse around retribution to enable a conjunction between public concern and academic underpinning. Wider implications concerning public understandings, convictions, rehabilitations and politics are discussed.

To the best of the authors’ knowledge, this is the first paper that explores the practical and theoretical implications of imposing a whole life order on those charged with sadistic or sexual-motivated murders.

This paper aims to explore how experienced nurses relate to hazing and uncover the underlying limits of tolerance for newcomers.

Data were collected through eight qualitative focus group interviews (n = 35) and analysed using reflexive thematic coding.

The analysis revealed three themes in the limits of experienced nurses’ tolerance of newcomers: “Don’t be sensitive”, “Prove your respectability” and “Accept your inequality of rights”.

The paper challenges existing perspectives on hazing motivation since tolerating newcomers is motivated by defending the status quo against threatening and challenging newcomers.

The study examines how calculative practices and accountability appear in a rural community of marginalised people in Egypt who depend on jasmine plantations that contribute to the production of global essences.

The data were collected from various sources, namely conversations with villagers, documents and relevant videos and news available on social media and the Internet. This study draws on the concepts of social accountability, the politics of blame avoidance and using calculative practices as a language to explain accountability in context.

The author found a lack of accountability on the part of the government and business owners, with serious implications for the livelihoods of people in a community that has been wholly dependent on jasmine plantations for a century. Power holders have deployed a blame-shifting game to avoid social responsibility. In response, calculative practices rather than advanced accounting tools are used by the poor in the community to induce power holders to be accountable.

The findings of this study show that authorities need to take proactive steps to address the disadvantaged position of powerless people in the lower echelons of society, recognising their accountability for those people.

This paper enhances the understanding of the status of calculative practices and accountability in a community of marginalised people who contribute to the production of global commodities. The paper also enhances the understanding of what goes on behind the scenes with popular and prestigious commodities, whose development is initiated in poor countries, with the end product marketed in rich Western countries.

This study aims to develop a large gap nanomagnetic liquid sealing technology to address the problems of significant deformation, vibration, and radial oscillation caused by harsh working conditions such as low assembly and processing accuracy, heavy load, and high speed in mechanical equipment.

Based on the principle of magnetic liquid sealing structure, a large gap magnetic fluid sealing scheme based on axial and radial distribution was proposed, equipped with self-made silicone oil–based magnetic fluid. Taking the common roller in mining equipment as an example, sealing performance tests were conducted using a mining roller running resistance test bench in the simulated underground environment.

In routine environmental tests, the running resistance of the new magnetic liquid sealing roller is reduced by an average of 7.6% and 34.3% compared to the labyrinth sealing roller, respectively; In long-term environmental tests, the running resistance of the new magnetic liquid sealing roller decreased by an average of 16.2% compared to the labyrinth sealing roller, it is recommended to equip it with self-made silicone oil–based magnetic fluid; In vibration environmental tests, the running resistance of the new magnetic liquid sealing roller is more stable compared to the magnetic liquid sealing roller with only axial distribution.

The research results have important theoretical and practical value in compensating for the shortcomings of magnetic fluid sealing structure and expanding the application fields of magnetic fluid.

This paper aims to propose a novel wheel-based multiaxis force sensor designed to detect the interaction forces and moments between the planetary rover’s wheel and the terrain, thereby assisting the rover in environmental perception.

The authors’ design approach encompasses the mechanical structure design, decoupling methods and component integration techniques, effectively incorporating multiaxis sensors into the forward-sensing wheel. This enables high-precision and high-reliability detection of wheel–terrain interaction forces and torques.

The designed wheel-based multiaxis force sensor exhibits a nonlinearity error of 0.45%, a hysteresis error of 0.56% and a repeatability error of 0.49%, meeting the requirements for practical applications. Furthermore, the effectiveness and stability of the designed wheel-based multidimensional force sensor have been validated through hardware-in-the-loop experiments and full-vehicle model testing.

Unlike previous methods that directly integrate multiaxis sensors into the forward-sensing wheel, the authors have designed the force sensing wheel with consideration of its limited design space and the need for high measurement accuracy. The effectiveness of the designed wheel-based multidimensional force sensor was ultimately validated through static calibration, hardware-in-the-loop experiments and full-vehicle model experiments.

This study aims to develop and evaluate epoxy coatings enhanced with micaceous iron oxide (MIO) and nanocrystalline aluminum (Al) particles, focusing on improving mechanical and corrosion-resistance properties for extended durability.

Three epoxy coatings were fabricated by incorporating 1, 2 and 3 wt% MIO with a fixed 2 wt% of ball-milled Al particles. The coatings were thoroughly characterized using field emission scanning electron microscopy, thermogravimetric analysis, hardness and scratch resistance tests, nanoindentation and electrochemical impedance spectroscopy (EIS). The EIS measurements in 3.5 wt% NaCl solution were performed over various immersion periods (1 h, 7, 14, 21 and 30 days) to study the coatings’ corrosion behavior.

The coating with 2 wt% MIO exhibited superior corrosion resistance across all immersion periods, outperforming the other formulations. Although corrosion resistance initially declined after seven days of immersion, it improved significantly after extended exposure (14–30 days) due to the formation of protective oxide layers on the coating surface. The combination of MIO and nanocrystalline Al also enhanced the mechanical properties of the epoxy coatings, delivering improved hardness, scratch resistance and overall stability.

This study highlights the synergistic effect of MIO and nanocrystalline Al particles in epoxy coatings, demonstrating their potential to enhance both mechanical performance and long-term corrosion resistance. The research offers valuable insights into the formulation of advanced epoxy coatings for applications requiring durability under harsh conditions.
