Different age groups display different shopping patterns in terms of how and where consumers buy products. During times of crisis, such behavioural differences become even more striking yet remain under-researched with respect to elderly consumers. This paper investigates the impact of age on retail-related behavioural changes and behavioural stability of elderly shoppers (in comparison to younger consumers) during a crisis.

The authors surveyed 643 Austrian consumers to assess the impact of perceived threat on behavioural change and the moderating effect of age groups. Based on findings from this survey, they subsequently conducted 51 semi-structured interviews to understand the causes of behavioural change and behavioural stability during a crisis.

Elderly shoppers display more stable shopping behaviour during a crisis compared to younger consumers, which is influenced by perceived threat related to the crisis. Such findings indicate that elderly shoppers reinforce their learnt and embedded shopping patterns. The causes of change and stability in behaviour include environmental and inter-personal factors.

Through the lens of social cognitive theory, protection motivation theory and dual process theory, this research contributes to an improved understanding of changes in shopping behaviour of elderly consumers, its antecedents and consequences during a time of crisis. The authors reveal reasons that lead to behavioural stability, hence the absence of change, in terms of shopping during a crisis. They further outline implications for retailers that might wish to better respond to shopping behaviours of the elderly.

Smart cities are where dreams are made true for the future. Abu Dhabi, UAE has been given the title of smartest city in the Middle East region in the “Smart City Index 2021.” UAE is known for its rich natural resources that established much business connectivity and developed the country economically and socially. It built an innovative infrastructure with equipment for healthcare and connected people through smartphones avoiding patient travel. This enhances the patient’s life expectancy and mortality rate. UAE’s net zero emission by 2050 will reduce the carbon footprint from its industries. UAE, on the other hand, is building sustainable, innovative, smart, and energy-efficient cities. It is the leading country in the world with digital transformation in the Arab world. In this study, the scope of Gulf countries moving toward smart cities are analyzed with air pollution. The slope of regression for PM₁₀ from linear regression was Khadija (0.9442), CI 0.9237 to 0.9647 and Khalifa City (0.9745), CI 0.9591 to 0.9900. In 2022, the CO₂ per capita emissions of UAE (25.8t) are higher over the world (4.7t). However, PM₁₀ and AQI seem to be pretty good in a few cities, enhancing the living style, and climate change mitigation.

Although various studies have shed light on why cities are a primary source of environmental pollution and how it affects climate change, the effects of city-level environmental deterioration on company ownership have yet to be investigated. In this context, our main objective is to investigate environmental pollution's impact on the ownership of informal enterprises in Indian metro cities (1 million or more population). This study considers micro (entrepreneurship-level) and macro (city-level) factors for the analysis by using mainly National Sample Survey unit-level data on ‘Unincorporated Non-Agricultural Enterprises’ in 2015–2016. Micro-level factors include access to toilet facilities, provision for solid waste management, provision for liquid waste management, etc. On the other hand, macro-level factors are the total number of registered motor vehicles (two-wheelers, cars, jeeps, tractors, omnibuses, trucks, taxis, buses, passenger autos and light motor vehicles) and air pollution (e.g. sulphur dioxide, nitrogen dioxide and particular matter emissions). The study explored the impact of environmental pollution on the differences in gender business ownership. According to the findings, both male- and female-owned proprietorships suffer from environmental degradation. Environmental contamination, however, puts female-owned businesses at greater risk than their male counterparts. Because of this, it is crucial to lessen environmental pollution by lowering air pollution and providing improved toilets, water and solid and liquid waste management systems. By reducing poverty and inequality, advancing a society that values equality between the sexes is necessary. Finally, we propose important policies to enable the city environment to improve entrepreneurship activities for sustainable economic development.

This study explores the factors influencing knowledge hiding (KH) in international construction projects (ICPs), focussing on the role of ethnic minorities (EMs) and interpersonal distrust (ID). It also aims to understand how these factors influence KH and explore the mediating effect of ID on the relationship between EMs and KH.

A survey questionnaire was developed and distributed to professionals participating in ICPs. We used structural equation modelling (SEM) to analyse 294 valid responses, examining the effect of EMs, ID and demographic variables on KH behaviours. Our approach integrates insights from social identity theory (SIT) and actor network theory (ANT) to provide a comprehensive framework for understanding the observed dynamics.

The findings reveal that EMs significantly influence KH behaviours, with ID partially mediating this relationship. Additionally, demographic variables such as gender and age also play significant roles in KH behaviours. However, the degree of education did not show a significant impact on KH. Our results emphasise the critical importance of addressing ID and fostering inclusive environments to reduce KH.

While our study sheds light on the complex dynamics of KH in ICPs, further research could explore additional contextual factors and organisational influences. While our study emphasises the importance of inclusive practices and trust-building to mitigate KH, it also recognises the need for a deeper understanding of power dynamics and organisational contexts.

Our findings underscore the importance of creating transparent and inclusive cultures of knowledge sharing (KS). Implementing inclusion initiatives and providing cultural awareness training can enhance project outcomes and organisational success. We also propose a practical framework to mitigate KH by promoting trust, inclusivity and effective KS practices.

This study contributes to the understanding of knowledge management in multicultural project teams by integrating SIT and ANT, offering a comprehensive perspective on the factors driving KH in ICPs. The findings pave the way for future investigations into power dynamics and organisational contexts within ICPs.

Induction heating processes need to adapt to complex geometries or variable processes that require a high degree of flexibility in the induction heating setup. This is usually done using complex inductors or adaptable resonant tanks, which leads to costly and constrained implementations. This paper aims to propose a multi-level, versatile power supply able to adapt the output to the required induction heating process.

This paper proposes a versatile multilevel topology able to generate versatile output waveforms. The methodology followed includes simulation of the proposed architecture, design of the power electronics, control and magnetic elements and laboratory tests after building a 10-level prototype.

The proposed converter has been designed and tested using an experimental prototype. The designed generator is able to operate at 1 kVpp and 100 A at 250 kHz, proving the feasibility of the proposed approach.

The proposed converter enables versatile waveform generation, enabling advanced tests and processes on induction heating system. The proposed system allows for multifrequency generation using a single inductor and converter, or advanced tests for inductive and capacitive components used on induction heating systems. Unlike previous multifrequency proposals, the proposed generator enables a significantly improved versatility in terms of operational frequency and amplitude in a single converter.

Drawing primarily on the Japanese context, this study aims to highlight this setting to emphasise the potential for tertiary-level self-access language centres to develop lifelong global citizenship, self-reflection and cross-cultural collaboration.

This inquiry calls on the community of practice approach to account for the shared interests motivating lifelong cross-cultural participation, the quality of social engagement between actors, and the material and cognitive tools called upon to realise global citizenship’s shared enterprise.

As argued here, embracing various cultures and inclusive participation can lead to a broader understanding of global citizenship, avoiding narrow-minded views of globalism through shared knowledge and critical practices. Further, self-access provides a cost-effective, technology-mediated alternative to bilateral student mobility, whereby digital community-building occasions cross-cultural practice that may be extended throughout a learner’s life, irrespective of their financial status or place of study.

This study is one of a select few drawing on the community of practice framework within the context of lifelong global citizenship. Nevertheless, such an approach remains primed for future development. With a social constructivist philosophy in view, the authors suggest complementary qualitative research approaches that highlight the socially situated nature of both disciplines.

This study aims to investigate the impact of online collective feminist actions on social media participation and the perceived value of social media as part of the social identity model of collective action (SIMCA).

A mixed methodology is used. Within the SIMCA model in the context of feminist collective actions, social identity, group-efficacy and fear predicted the intention of online collective action participation in the first part (quantitative) of the study. Contrary to predictions, the influence of anger on the intention to participate in collective action was negative. In-depth interviews are conducted in the study’s second (qualitative) part to investigate why individuals do not participate in collective actions despite their anger at violence against women.

The concept of online feminist collective action, from the perspective of the SIMCA model, deals with violence against women in the context of social marketing, revealing the importance of online collective actions as an antecedent of social media participation and the perceived value of social media. The possible causes of the negative impact of anger, which is an important emotion within the framework of the SIMCA model, on online feminist collective action were determined, and a contribution was made to the social marketing literature in the context of women’s rights.

The study makes three major contributions to the literature. First, women’s rights are addressed in the context of online collective action, an issue that has received little attention in social marketing. Second, in the context of the social identity theory of collective action, online collective feminist action and its predecessors are addressed. Finally, the Turkish case is used to highlight the probable causes of anger’s negative impact on collective action.

This study explores the integration of corporate reporting by Mitsubishi, a large Japanese company, using a culturally sensitive narrative that combines and reconciles Japanese and Western corporate values in one story.

We use an analytical framework drawing on insights borrowed from narratology and the notion of wrapping – the traditional art of packaging as communication.

We find that Mitsubishi is a survivor company that uses different corporate reporting frameworks during its reporting journey to construct a bespoke narrative of its value creation and cultural values. It emplots narratives to convey a story presenting the impression that Mitsubishi is a Japanese corporation but is compatible with Western neo-liberal ideology, making bad news palatable to its stakeholders and instilling confidence in the future.

Wrapping is a culturally sensitive form of impression management used in the integration of corporate reporting. Therefore, rather than assuming that companies blatantly manipulate their image in corporate reports, we suggest that future research should focus on how narratives are constructed and made sense of, situating them in the context of local culture and traditions.

The findings should interest scholars, report preparers, policymakers, and the IFRS, considering the recent release of the IFRS Sustainability Disclosure Standards designed to reduce the so-called alphabet soup of corporate reporting. By following Mitsubishi’s journey, we learn how and why the notion of integrated reporting was adopted and integrated with other reporting frameworks to create narratives that together convey a story of a global corporation compliant with Western neoliberal ideology. It highlights how Mitsubishi used integrated reporting to tell its story rather than as a rigid reporting framework, and the same fate may apply to the new IFRS Sustainability Reporting Standards that now include integrated reporting.

The study offers a new perspective on corporate reporting, showing how the local societal discourses of cultural heritage and modernity can shape the journey of the integration of corporate reporting over time.

Plasma technology has become of great interest in a wide variety of industrial and domestic applications. Moreover, the application of plasma in the domestic field has increased in recent years due to its applications to surface treatment and disinfection. In this context, there is a significant need for versatile power generators able to generate a wide range of output voltage/current ranging from direct current (DC) to tens of kHz in the range of kVs. The purpose of this paper is to develop a highly versatile power converter for plasma generation based on a multilevel topology.

This paper proposes a versatile multilevel topology able to generate versatile output waveforms. The followed methodology includes simulation of the proposed architecture, design of the power electronics, control and magnetic elements and test laboratory tests after building an eight-level prototype.

The proposed converter has been designed and tested using an experimental prototype. The designed generator is able to operate at 10 kVpp output voltage and 10 kHz, proving the feasibility of the proposed approach.

The proposed converter enables versatile waveform generation, enabling advanced studies in plasma generation. Unlike previous proposals, the proposed converter features bidirectional operation, allowing to test complex reactive loads. Besides, complex waveforms can be generated, allowing testing complex patterns for optimized cold-plasma generation methods. Besides, unlike transformer- or resonant-network-based approaches, the proposed generator features very low output impedance regardless the operating point, exhibiting improved and reliable performance for different operating conditions.

This paper aims to address the safety concerns of path-planning algorithms in dynamic obstacle warehouse environments. It proposes a method that uses improved artificial potential fields (IAPF) as expert knowledge for an improved deep deterministic policy gradient (IDDPG) and designs a hierarchical strategy for robots through obstacle detection methods.

The IAPF algorithm is used as the expert experience of reinforcement learning (RL) to reduce the useless exploration in the early stage of RL training. A strategy-switching mechanism is introduced during training to adapt to various scenarios and overcome challenges related to sparse rewards. Sensor inputs, including light detection and ranging data, are integrated to detect obstacles around waypoints, guiding the robot toward the target point.

Simulation experiments demonstrate that the integrated use of IDDPG and the IAPF method significantly enhances the safety and training efficiency of path planning for mobile robots.

This method enhances safety by applying safety domain judgment rules to improve APF’s security and designing an obstacle detection method for better danger anticipation. It also boosts training efficiency through using IAPF as expert experience for DDPG and the classification storage and sampling design for the RL experience pool. Additionally, adjustments to the actor network’s update frequency expedite convergence.
