Hydrodynamics of quantum vortices on a closed surface
Authors: Xiong Yanqi , Yu Xiaoquan 
Published: February 2024

We develop a neutral vortex fluid theory on closed surfaces with zero genus. The theory describes collective dynamics of many well-separated quantum vortices in a superfluid confined on a closed surface. Comparing to the case on a plane, the covariant vortex fluid equation on a curved surface contains an additional term proportional to Gaussian curvature multiplying the circulation quantum. This term describes the coupling between topological defects and curvature in the macroscopic level. For a sphere, the simplest nontrivial stationary vortex flow is obtained analytically and this flow is analogous to the celebrated zonal Rossby-Haurwitz wave in classical fluids on a nonrotating sphere. For this flow the difference between the coarse-grained vortex velocity field and the fluid velocity field generated by vortices is solely driven by curvature and vanishes in the corresponding vortex flow on a plane when the radius of the sphere goes to infinity.

Authors: Kostagiolas Petros , Platis Charalampos , Belitsas Alkeviadis , Psomiadi Maria Elisavet , Niakas Dimitris 
Published: February 2024

PurposeThe higher-level aim of this study is to investigate the impact of health information needs satisfaction on the fear of COVID-19 for the general population. The investigation is theoretically grounded on Wilsons’ model of information seeking in the context of inquesting the reasons for seeking health information as well as the information sources the general population deploy during the COVID-19 pandemic.Design/methodology/approachThis cross-sectional survey examines the correlations between health information seeking behavior and the COVID-19 generated fear in the general population through the application of a specially designed structured questionnaire which was distributed online. The questionnaire comprised four main distinct research dimensions (i.e. information needs, information sources, obstacles when seeking information and COVID-19 generated fear) that present significant validity levels.FindingsIndividuals were motivated to seek COVID-related health information to cope with the pandemic generated uncertainty. Information needs satisfaction as well as digital health literacy levels is associated with the COVID-19 generated fear in the general population. Finally, a conceptual framework based on Wilsons’ macro-model for information seeking behavior was developed to illustrate information needs satisfaction during the pandemic period. These results indicate the need for incentives to enhance health information needs satisfaction appropriately.Originality/valueThe COVID-19 generated fear in the general population is studied through the information seeking behavior lenses. A well-studied theoretical model for information seeking behavior is adopted for health-related information seeking during pandemic. Finally, digital health information literacy levels are also associated with the fear of COVID-19 reported in the authors’ survey.
Consumers’ evaluation of ethical luxury advertisements: the roles of ethical consumer guilt and self-construal
Authors: Shin Hanna , Li Yan , Youn Nara 
Published: February 2024

PurposeThe authors investigated the factors influencing consumer evaluations of advertisements for ethical luxury products that incorporate animal rights and protection concerns. The authors empirically examined how ethical messages influence advertisement persuasiveness through ethical consumer guilt and positively impact consumer evaluations of ethical luxury products. Furthermore, the authors explored the moderating role of consumers’ independent versus interdependent self-construals.Design/methodology/approachThe authors conducted four experimental studies on the interplay among ethicality, luxury brand positioning and self-construal. Moderated mediation analyses revealed that moral emotions were responsible for the effect of ethical luxury advertisements that address animal welfare on brand attitude.FindingsAdvertisement messages signaling a luxury brand’s ethical efforts increase empathy through ethical consumer guilt, thereby generating favorable attitudes toward luxury products. However, this effect is limited to consumers with independent self-construal in South Korea and the United States of America.Originality/valueThe authors offer novel insights into the roles of ethical consumer guilt and empathy in the positive effects of ethical messages from luxury brands. Furthermore, the authors identified brand type and self-construal as boundary conditions for the effects observed across different consumer groups and markets.

Published: February 2024

PurposeThis study aims to increase knowledge of the ability of nutrition labels to guide consumer choices in real-life environments.Design/methodology/approachFood consumption and plate waste data were collected from two self-service restaurants (SSR) with different customer groups over six observation days: three control and three intervention (with nutrition labelling) periods. Study Group 1 consisted of vocational school students, mostly late adolescents (N = 1,710), and Group 2 consisted of spa hotel customers, mostly elderly (N = 1,807). In the experimental restaurants, the same food was served to the buffets during the control and intervention periods.FindingsThe nutrition label in the lunch buffet guides customers to eat fewer main foods and salads and to select healthier choices. Increased consumption of taste enhancers (salt and ketchup) was observed in the study restaurants after nutritional labelling. Nutrition labelling was associated with a reduction in plate waste among the elderly, whereas the opposite was observed among adolescents.Originality/valueThe results provide public policymakers and marketers with a better understanding of the effects of nutrition labelling on consumer behaviour. Future studies should further evaluate the effects of nutrition labelling on the overall quality of customer diets and the complex environmental, social, and psychological factors affecting food choices and plate waste accumulation in various study groups.
The impact of directors’ green experience on firm environmental information disclosure: evidence from China
Authors: Liu Zhui , Sun Xiaoxuan , Yin Yishuai 
Published: February 2024

Purpose
This study aims to examine the impact of directors’ green experience on the disclosure of environmental information by firms. Furthermore, it investigates the mediating role of firm green culture and the moderating effect of Confucianism in this mediation process.

Design/methodology/approach
The selected sample for this study comprises the A-share listed firms from 2010 to 2020. The data on “directors’ green experiences,” “Confucianism” and “green culture” were manually collected and organized, while other data were obtained from China Stock Market & Accounting Research Database. After eliminating corporations with ST, *ST and missing data, a total of 29,419 samples were obtained. The hypotheses were tested using a multiple linear regression model, and statistical analysis was performed using Stata 16.0.

Findings
The findings of this study reveal that directors’ green experience positively influences firm environmental information disclosure, and firm green culture mediates this relationship. Moreover, Confucianism moderates the impact of directors’ green experience on firm environmental information disclosure, as well as the mediating role of green culture in the relationship between directors’ green experience and firm environmental information disclosure.

Originality/value
The disclosure of environmental information plays a significant role in promoting a firm’s environmental performance as well as its competitive advantage. While previous studies examine various factors leading to firms’ environmental information disclosure, the influence of managerial characteristics on firm environmental information disclosure has not received adequate research attention. The present study investigates the effect of directors’ green experience on environmental information disclosure, contributing to the existing literature on firms’ environmental information disclosure and managerial features. Meanwhile, it enriches the literature on firm governance and imprinting theory.

Published: February 2024

Purpose
This study aims to explore the range of sustainability-related discourses by the stakeholders within a particular Finnish Higher Education Institution (HEI); interaction between the discourses and the context of the HEI; and the extent to which different understandings of sustainability cause challenges for the implementation of the university strategy for sustainability. Specifically, the paper explores how the employees within the HEI make sense of sustainability in their teaching, research and daily life and the extent to which sustainability-related discourses are aligned with the university strategy.

Design/methodology/approach
This research draws upon collected qualitative and quantitative data. It focuses on individual discourses by executives, teaching and research staff within an HEI regarding their understandings of sustainability and the Sustainable Development Goals (SDGs).

Findings
This paper illustrates the key challenges of sustainability and SDG implementation that may emerge in HEIs due to varied understandings. The results indicate a need for efficient HEI strategic vision communication and consideration of the stakeholders’ multiplicity of sustainability values.

Originality/value
This paper sheds light on the challenges involved in seeking to enhance sustainable development in an academic setting with multiple disciplines and categories of staff guided by academic freedom. The analysis thus advances the understanding of academic sustainability-related discourses and framings as well as mechanisms through which the implementation of sustainability-related efforts can be enhanced in such a context.

Published: February 2024

PurposeAutonomous mobile robots (AMRs) play a crucial role in industrial and service fields. The paper aims to build a LiDAR-based simultaneous localization and mapping (SLAM) system used by AMRs to overcome challenges in dynamic and changing environments.Design/methodology/approachThis research introduces SLAM-RAMU, a lifelong SLAM system that addresses these challenges by providing precise and consistent relocalization and autonomous map updating (RAMU). During the mapping process, local odometry is obtained using iterative error state Kalman filtering, while back-end loop detection and global pose graph optimization are used for accurate trajectory correction. In addition, a fast point cloud segmentation module is incorporated to robustly distinguish between floor, walls and roof in the environment. The segmented point clouds are then used to generate a 2.5D grid map, with particular emphasis on floor detection to filter the prior map and eliminate dynamic artifacts. In the positioning process, an initial pose alignment method is designed, which combines 2D branch-and-bound search with 3D iterative closest point registration. This method ensures high accuracy even in scenes with similar characteristics. Subsequently, scan-to-map registration is performed using the segmented point cloud on the prior map. The system also includes a map updating module that takes into account historical point cloud segmentation results. It selectively incorporates or excludes new point cloud data to ensure consistent reflection of the real environment in the map.FindingsThe performance of the SLAM-RAMU system was evaluated in real-world environments and compared against state-of-the-art (SOTA) methods. The results demonstrate that SLAM-RAMU achieves higher mapping quality and relocalization accuracy and exhibits robustness against dynamic obstacles and environmental changes.Originality/valueCompared to other SOTA methods in simulation and real environments, SLAM-RAMU showed higher mapping quality, faster initial aligning speed and higher repeated localization accuracy.

PurposeDespite an enormous body of literature on conflict management, intra-group conflicts vis-à-vis team performance, there is currently no study investigating the conflict prevention approach to handling innovation-induced conflicts that may hinder smooth implementation of big data technology in project teams.Design/methodology/approachThis study uses constructs from conflict theory, and team power relations to develop an explanatory framework. The study proceeded to formulate theoretical hypotheses from task-conflict, process-conflict, relationship and team power conflict. The hypotheses were tested using Partial Least Square Structural Equation Model (PLS-SEM) to understand key preventive measures that can encourage conflict prevention in project teams when implementing big data technology.FindingsResults from the structural model validated six out of seven theoretical hypotheses and identified Relationship Conflict Prevention as the most important factor for promoting smooth implementation of Big Data Analytics technology in project teams. This is followed by power-conflict prevention, prevention of task disputes and prevention of Process conflicts respectively. Results also show that relationship and power conflicts interact on the one hand, while task and relationship conflict prevention also interact on the other hand, thus, suggesting the prevention of one of the conflicts could minimise the outbreak of the other.Research limitations/implicationsThe study has been conducted within the context of big data adoption in a project-based work environment and the need to prevent innovation-induced conflicts in teams. Similarly, the research participants examined are stakeholders within UK projected-based organisations.Practical implicationsThe study urges organisations wishing to embrace big data innovation to evolve a multipronged approach for facilitating smooth implementation through prevention of conflicts among project frontlines. This study urges organisations to anticipate both subtle and overt frictions that can undermine relationships and team dynamics, effective task performance, derail processes and create unhealthy rivalry that undermines cooperation and collaboration in the team.Social implicationsThe study also addresses the uncertainty and disruption that big data technology presents to employees in teams and explore conflict prevention measure which can be used to mitigate such in project teams.Originality/valueThe study proposes a Structural Model for establishing conflict prevention strategies in project teams through a multidimensional framework that combines constructs like team power conflict, process, relationship and task conflicts; to encourage Big Data implementation.
The effect of online company responses on app review quality
Authors: Su Qiuli , Namin Aidin , Ketron Seth 
Published: February 2024

PurposeThis paper aims to investigate textual characteristics of customer reviews that motivate companies to respond (sentiment negativity and sentiment deviation) and how aspects of these company responses (response intensity, length and tailoring) affect subsequent customer review quality (comprehensiveness and readability) over time.Design/methodology/approachLeveraging a large data set from a leading app website (Shopify), the authors combine text mining, natural language processing (NLP) and big data analysis to examine the antecedents and outcomes of online company responses to reviews.FindingsThis study finds that companies are more likely to respond to reviews with more negative sentiment and higher sentiment deviation scores. Furthermore, while longer company responses improve review comprehensiveness over time, they do not have a significant influence on review readability; meanwhile, more tailored company responses improve readability but not comprehensiveness over time. In addition, the intensity (volume) of company responses does not affect subsequent review quality in either comprehensiveness or readability.Originality/valueThis paper expands on the understanding of online company responses within the digital marketplace – specifically, apps – and provides a new and broader perspective on the motivations and effects of online company responses to customer reviews. The study also extends beyond the short-term focus of prior works and adds to literature on long-term effects of online company responses to subsequent reviews. The findings provide valuable insights for companies (especially those with apps) to enhance their online communication strategies and customer engagement.
“Thriving at work” or not? Research on the effects of performance pressure based on achievement motivation theory and two-factor theory
Authors: He Qi , Fu Jingtao , Wu Wenhao , Feng Siqi 
Published: February 2024

PurposeBased on achievement motivation theory and two-factor theory, this research aimed to synergize cooperative goal interdependence (refer to possessing incentive factors) and illegitimate tasks (refer to the absence of security factors) and build a triple interaction model in the process of performance pressure affecting employees’ thriving at work.Design/methodology/approachThis research collected 291 valid data through a two-point time-lagged method to test the direct effect of performance pressure on employees’ thriving at work and its moderating mechanism.FindingsPerformance pressure has a significant positive effect on employees’ thriving at work. Cooperative goal interdependence imposes an enhanced moderating effect between performance pressure and employees’ thriving at work. Illegitimate task imposes an interfering moderating effect between performance pressure and employees’ thriving at work and further interferes the enhanced moderating effect of cooperative goal interdependence.Practical implicationsUnder the premise of advocating for employees to internalize performance pressure originating from the organizational performance management system into their own achievement motivation, leaders should establish incentive systems and security systems for employees to realize self-achievement through the process of goal management and task management.Originality/valueThis research confirmed the joint determination of incentive effect and insecurity effect on employees’ achievement motivation by cooperative goal interdependence and illegitimate task and revealed the boundary conditions of employees’ choice of thriving at work.
Waqf for accelerating socioeconomic development: a proposed model with focus on Pakistan
Authors: Ayub Muhammad , Khan Khurram , Khan Mansoor , Ismail Muhammad 
Published: February 2024

Purpose
The unique institution of waqf that was ignored during the colonization of the Muslim areas has to be revived to play its role in shared growth, social inclusion and cohesion in society. This research paper aims to explore the role of waqf as an instrument for a sustainable growth system and to suggest a model for socioeconomic development in an economy like that of Pakistan.

Design/methodology/approach
This qualitative research is based on analytical methods to arrive at the frameworks and a model that could facilitate the revival of waqf for community development/social inclusion in economies like that of Pakistan.

Findings
As most of the OIC member states like Pakistan are facing serious financial problems due to debt servicing obligations, promoting Waqf for various socioeconomic and cultural functions is a vital requirement for such economies. The inability of the state institutions in providing necessary civic, health and education facilities to the public is causing serious harm to the balance of the society. It requires promoting a formal system of charity and using FinTech for waqf-based donations and financing the micro businesses. The perpetuity complimented by the profitability of the waqf properties makes the waqf institutions sustainable and effective when compared to individual charities.

Research limitations/implications
This is conceptual research discussing the potential of waqf in light of its historical role. Researchers may undertake empirical studies on awqaf operations in various jurisdictions and their role in the empowerment of the poor.

Practical implications
The research will provide the researchers with insight into the potential of waqf as a tool for community development. Besides, it will enable policymakers and implementation authorities to socialize charity for sustained benefits and welfare.

Originality/value
To the best of the authors’ knowledge, it is the first major research that discusses the role of waqf in economies facing budgetary and trade deficits in the eradication of poverty and the promotion of social and economic entrepreneurship in realizing the community development targets for the economies like that of Pakistan.
Is ‘more’ better? Testing the assumption that larger local governments are more sustainable
Authors: Drew Joseph , Miyazaki Masato , McQuestin Dana 
Published: February 2024

AbstractIt is commonly assumed that bigger local governments will be more financially sustainable. Indeed, public policymakers are often prompted to make boundary change decisions according to idealised structures that they assume will lead to stronger local governments. In addition, many local government regulators urge councillors to work for growth in order to become sustainable. However, the assumption that size is associated with financial sustainability has seldom been put to robust empirical test. In this work, we first explore the theoretical considerations relevant to the supposed association between size and sustainability. Following this, we employ a comprehensive 5‐year panel of data to test the association. The evidence we derive stands in stark contrast to the assumptions of many policy architects. We conclude our work with an enumeration of the surprising implications that our results point to with respect to future public policy prescriptions.Points for practitionersTheoretical considerations are ambiguous with respect to the assumption that larger local governments might be more financially sustainable.A regression of a 5‐year panel of data demonstrates that larger local governments are indeedlessfinancially sustainable.Our results suggest the need for a radical re‐appraisal of policies surrounding amalgamation, de‐amalgamation, and which local governments are most at risk of financial failure.
