Extreme high temperatures are a significant feature of global climate change and have become more frequent and intense in recent years. These pose a significant threat to both human health and economic activity, and thus are receiving increasing research attention. Understanding the hazards posed by extreme high temperatures are important for selecting intervention measures targeted at reducing socioeconomic and environmental damage.

In this study, detrended fluctuation analysis is used to identify extreme high-temperature events, based on homogenized daily minimum and maximum temperatures from nine meteorological stations in a major grassland region, Hulunbuir, China, over the past 56 years.

Compared with the commonly used functions, Weibull distribution has been selected to simulate extreme high-temperature scenarios. It has been found that there was an increasing trend of extreme high temperature, and in addition, the probability of its indices increased significantly, with regional differences. The extreme high temperatures in four return periods exhibited an extreme low hazard in the central region of Hulunbuir, and increased from the center to the periphery. With the increased length of the return period, the area of high hazard and extreme high hazard increased. Topography and anomalous atmospheric circulation patterns may be the main factors influencing the occurrence of extreme high temperatures.

These results may contribute to a better insight in the hazard of extreme high temperatures, and facilitate the development of appropriate adaptation and mitigation strategies to cope with the adverse effects.

The purpose of this study is to investigate the effects of the activity-based workspace (ABW) on employee belonging. Place attachment theory (PAT) is used as a proxy to understand and measure the belongingness of employees to their physical workplaces.

A case study of a bank’s newly retrofitted ABW office is conducted, providing fresh perspectives on the effect of ABW on employee belonging. A questionnaire survey was used to understand employee belongingness. Surveys are conducted with employees of the bank (n = 100) who experienced the transition from the conventional open-plan office with designated seats to an ABW, to understand and compare the change in employee belonging after the transition, by studying the level of belonging achieved in the space before and after.

The results showed that there was a positive sense of belongingness amongst employees working in the ABW space, as per the PAT framework and an increased sense of belongingness compared with the previous conventional open-plan office. However, ABWs were found to also have a negative effect on employees’ sense of control and security.

Maslow’s hierarchy of needs indicates that a feeling of belonging is fundamental to humans. The need for belonging is also applicable in the workplaces of today’s progressive corporate organisations, where there is increased pressure and incentive to appeal to and retain talent. This research was conducted in response to the huge growth in interest in activity-based working across the corporate real estate community. As there has been no prior research done in the area of the emotional need for belongingness in ABW.

This paper explores the “Western” concept of psychological capital in the People's Republic of China (PRC) and highlights critical areas of divergence and notable dimensions of similarity.

This is an empirical study conducted in a wide range of Chinese organisational forms, employing an inductive approach based on critical incident technique.

This research showed that the concept of psychological capital appears to have a degree of applicability and salience in China. A series of dimensions common in Western organisations were found in our research, including Optimism, Creativity, Resiliency, Self‐confidence, Forgiveness and Gratitude, Courage and Ambition (Hope). These were found to be common types of psychological capital both in China and in the West. However, the dimensions of Courtesy and Humility (Qian‐gong‐you‐li in Chinese), Self‐possession and Sincerity fell into the “different” category.

This paper is a first attempt to examine psychological capital in a range of organisational forms and industrial sectors in China using a grounded theory approach. It not only reports various dimensions of Chinese psychological capital, some unique to this research, but also compares and contrasts these dimensions between China and the West, highlighting further research opportunities.

This study aims to reduce the harm of industrial lubricants to consumers. Composite aluminum-based grease (CAG) was prepared, and medical-grade montmorillonite (M-MMT) was used to improve the antiwear performance of the prepared grease.

The influence of the additive (M-MMT) on the tribological performance is mainly investigated using a ball-disc wear tester, and the wear scar surface about the disc was characterized by white light interferometer and electrochemical workstation. Moreover, the cell viability test was used to evaluate the safety of the grease.

The results indicated that for the grease containing 1.5% M-MMT, the average coefficient of friction was reduced by about 46% compared with the CAG, the wear volume of the disc reduced by about 74%. Moreover, CAG and 1.5% M-MMT-containing CAG were proved safety by means of the cell viability test.

The integral properties of CAG can be improved with the medical-grade materials as the additives, while ensuring the safety.

The purpose of this paper is to critically review the extant western literature on political skill and impression management in human resource management and organisational behaviour and applies an inductive approach to explore an equal Chinese concept of office politics in the People’s Republic of China (PRC).

An empirical study conducted in a wide range of Chinese organisational forms, employing an inductive approach based on critical incident technique.

Data collected from 173 employees supported this model and indicated the existence of 14 clusters of behaviours that characterise political skill, impression management and the overlap between the two. Extending impression management theory, the authors found that individual players’ political skill drives the dynamics of Chinese office politics and may help a subordinate gain a favourable image with superiors and serve as the overlap between individual political skill and impression management from the Chinese perspective.

The authors used a grounded theory approach to report the construct of a Chinese concept of office politics in the PRC, which is much similar to the western concept of political skill in organisation. Compared with western political skill literature, this study found both universal and cultural-specific phenomena on political perspective in Chinese organisations.

The purpose of this paper is to provide a framework for enhancing security policy management in the Grid.

The Grid security policy reconciliation problem is presented. A generic view on the security policy notion is adopted and the security policy ontology notion is introduced and used.

In the course of this work it was found that, in order to enhance security policy management in the Grid, Grid entities should have the ability to negotiate their security policies. It was also found that, in order to achieve security policy negotiation, effective security policy semantics manipulation towards security policy reconciliation is needed. Finally, it was established, through the use of an example, that if appropriate means are used for security policy reconciliation then incompatible security policy representations can be transformed into compatible ones.

Research limitations stem from the adoption of a generic view on the security policy notion and the selection of identification and authentication security policies as the focal point of the proposed framework. Research implications include the possibility of examining how existing security policy reconciliation models can be incorporated in this generic framework. The possibility of investigating how such a framework can lead to a security policy knowledge management tool for Grid administrators is also demonstrated.

Practical implications of this work include the establishment of a common framework for security information exchange between Grid entities.

This paper proposes a framework for enhancing security policy management in the Grid. The proposed framework can be used by researchers as a reference and by security experts in order to reduce ambiguity concerning the interpretation of security policies expressed in different forms, by negotiating Grid entities.

This paper aims to generate novel insights in supply chain management by reviewing studies related to counterfeiting and piracy issues with a particular emphasis on theoretical works.

A systematic literature review of more than 100 peer-reviewed academic papers is conducted. The authors first introduce the social acceptance of counterfeiting and piracy to explain the existence of these illegal products. After that, they focus on the negative effect of counterfeiting and piracy on supply chain management and society while mentioning their positive and normative effects carefully under certain circumstances.

People have been attempting to reveal the impacts of counterfeiting and piracy on customers, licit firms, industry sectors, governments and the society as a whole. The negative impacts of counterfeiting and piracy on legal firms and licit supply chains is examined thoroughly in the literature; however, benefits from counterfeiting and piracy are also pointed out. Additionally, researchers are interested in firms’ reactions toward this phenomenon. Based on heuristics from the above analysis, it is fruitful to conduct this research in a theme of supply chain management.

Most studies on counterfeiting and piracy are not from a supply chain management perspective and mainly focus on their effect on consumers or a single firm. To the best of the authors’ knowledge, this paper is one of few studies that incorporate the key aspects of counterfeiting and piracy into supply chain management and also highlight several important directions for future research in the sense of supply chain.

This study aims to investigate the effect of leader-leader exchange (LLX) on knowledge sharing through feedback-seeking behavior. The study also explores the moderating role of power distance.

A cross-sectional data of 290 knowledge workers from manufacturing and service firms in India were taken as a sample of the study. The hypotheses were tested using confirmatory factor analysis, structural equation modeling and hierarchical regression.

The results showed that LLX positively affects knowledge sharing and feedback-seeking behavior mediates the relationship between LLX and knowledge sharing. Moreover, power distance does not moderate the relationship between LLX and knowledge sharing.

The present study one of its kind explores the relationship between LLX, feedback-seeking behavior, knowledge sharing and power distance.

Product counterfeiting has been ubiquitously observed in various segments of the supply chain. The intrinsic values of brands create more opportunities for counterfeiting. The damaging reputation of such brands leaves them to deal with the fallouts of counterfeits. Hence, such companies address them mainly through legal action, price and quality strategy. However, consumer characteristics and the random distribution of counterfeit products to the consumer types affect the effectiveness of a counter strategy. This paper aims to generate insights on how to leverage digital technology to curb counterfeit entities with consideration of consumer characteristics and the random distribution of counterfeits to them.

The authors used game theory and vertical differentiation model to understand and encounter deceptive counterfeiting of brand products. The study understands the economic relationship between a brand product manufacturer and consumer types based on their awareness. Further, the authors have considered different cases in the model to gain useful insights.

The results reveal that when the consumers are proactive, informed and value-conscious brand product manufacturers take digital technology counterstrategy to earn the maximum revenue. Hence, this analysis highlights that the effectiveness of a counterstrategy critically depends on the consumer characteristics, whether they are proactive, informed or unaware.

The study outlines that brand product manufacturers must emphasize on the digital supply chain, product redesign and product tracking facility to empower informed and value-conscious and proactive consumers. Moreover, the government should take steps to create awareness among uninformed consumers via information campaigns.

This paper incorporates the role of consumers and brand product manufacturers to understand and address the deceptive counterfeiting issue.

Stab-resistant body armor (SRBA) is used to protect the body from sharp knives. However, most SRBA materials currently have the disadvantages of large weight and thickness. This paper aims to prepare lightweight and high-performance SRBA by 3D printing truss structure and resin-filling method.

The stab resistance truss structure was prepared by the fused deposition modeling method, and the composite structure was formed after filling with resin for dynamic and quasi-static stab tests. The optimized structural plate can meet the standard GA68-2019. Digital image correlation technology was used to analyze the local strain changes during puncture. The puncture failure mode was summarized by the final failure morphologies. The explicit dynamics module in ANSYS Workbench was used to analyze the design of the overlapped structure stab resistance process in this paper.

The stab resistance performance of the 3D-printed structural plate is affected by the internal filling pattern. The stab resistance performance of 3D-printed structural parts was significantly improved after resin filling. The 50%-diamond-PLA-epoxy, with a thickness of only 5 mm was able to meet the stab resistance standard. Resins are used to increase the strength and hardness of the material but also to increase crack propagation and reduce the toughness of the material. The overlapping semicircular structure was inspired by the exoskeleton structure of the demon iron beetle, which improved the stab resistance between gaps. The truss structure can effectively disperse stress for toughening. The filled resin was reinforced by absorbing impact energy.

The 3D-printed resin-filled truss structure can be used to prepare high-performance stab resistance structural plates, which balance the toughness and strength of the overall structure and ultimately reduce the thickness and weight of the SRBA.
