Collective oscillations of Bose-Einstein condensates in a synthetic magnetic field
Authors: He Huaxin , Pang Fengtao , Zhang Yongping , Qu Chunlei 
Published: February 2025

We study the collective oscillations of spin-orbit-coupled Bose-Einstein condensates in the presence of position-dependent detuning. Specifically, we explore the quadrupole modes of the system using both numerical and analytical approaches based on the Gross-Pitaevskii equation and hydrodynamic theory. Due to spin-orbit coupling and the synthetic magnetic field, the xy scissors mode couples with a superposition of the three diagonal quadrupole modes (x2,y2, and z2), resulting in the characteristic beating effect. The remaining two scissors modes, xz and yz, are coupled, giving rise to a Lissajous-like pattern that is highly sensitive to the excitation method and orientation of the synthetic magnetic field. Furthermore, we find that anisotropic interactions as well as the direction of the synthetic magnetic field, can significantly influence the oscillation amplitude and frequency of the quadrupole modes. These findings highlight the potential of Bose-Einstein condensates under synthetic magnetic fields for quantum sensing applications, such as magnetic field gradient measurements, and provide a promising foundation for future experimental research and technological development.

Optimal control for hover pendulum motion of unmanned helicopter
Authors: Hongyan Zhang , Xiaoyong Guo 
Published: February 2025

Purpose
During the authors’ practical experiments about designing hover controller for unmanned helicopter, they find pendulum motion exists, thus destroying their expected control performance, such as perfect tracking, target detection, accurate attacking etc., so they turn to study how to suppress pendulum motion through designing one additional controller to guarantee pendulum motion sufficiently small. More specifically, the detailed mechanism of hover pendulum motion is analyzed to yield one accurate nonlinear dynamical equation, corresponding to hover pendulum motion. To apply the existed linear optimal control strategy directly, the necessary linearization process is needed to derive one approximated linear state equation, including the explicit form of control input. After describing their idea about pendulum control structure from the point of practice, linear optimal control strategy is proposed to design the ideal controller without external noise. Then its improved robust controller is also given through solving their difference game problem or min-max problem. From their obtained closed forms of the pendulum controller, they are all one linear state feedback form, being convenient to implement in practical engineering. Finally, to achieve the mission of theory for application, they use their established practical platform to do some simulations, so proving the theoretical results. The purpose of this paper aims to design one optimal controller to suppress hover pendulum motion for unmanned helicopter.

Design/methodology/approach
First, considered the practical hover motion of unmanned helicopter, its detailed mechanism is analyzed to get one linear state equation after the authors’ complex mathematical derivation. Second, their idea of control structure and control design is applied to design one linear state feedback controller through the derived optimal control strategy. Third, one practical platform is established to prove their control idea.

Findings
From the authors’ introduction and knowledge, control exists everywhere. As unmanned helicopter has become increasingly important as one tactical weapon, so they think how to design controller for hover pendulum motion, while suppressing the hover pendulum. Specifically, they give the detailed theoretic derivation and practical platform.

Originality/value
To the best knowledge of the authors’ knowledge, pendulum motion control is to stop the swing as soon as possible and suppress the oscillatory motion of pendulum angle. Then, based on that linear state equation for hover pendulum motion, linear optimal control strategy is applied to achieve above two dual missions, i.e. controlling the motion or pendulum suspension point and eliminating or suppressing the pendulum phenomenon.
Analysis of changes in European air traffic flow after the 2022 armed conflict in Ukraine
Authors: Drupka Grzegorz , Rogalski Tomasz , Wałek Łukasz 
Published: February 2025

Purpose
This paper aims to present the scale of the impact of the war in Ukraine on air traffic within neighbouring countries. When assessing the scale of the impact of the war, the airspace and aerodromes of European countries whose borders are shared with countries involved in the armed conflict were analysed.

Design/methodology/approach
The change in the number of aircraft operations, expressed as a percentage share of flights over the years 2016–2022, was used as an assessment criterion. The average delays were also rated. During the analysis of changes, the alleged reasons for delays resulting from the comprehensive reorganization of air traffic were shown.

Findings
The data comparison method is presented as a convenient way of analysing the data, allowing to present the result as changes in air traffic, also showing significant delays and their cause.

Research limitations/implications
The gradual restoration of air connections after the COVID-19 pandemic made it difficult to precisely assess changes in traffic. Therefore, using a wider range of years allowed to obtain the result – which was to determine information about the increase in the number of flights and aerodrome traffic compared to previous years.

Originality/value
This paper presents data on the impact of war on air traffic in a comparative manner. The result contributes to future research on air traffic management practices to efficiently and harmoniously deploy flights in case of adverse events, thus minimizing delays and traffic disorder.

Published: February 2025

PurposeThis article investigates the impact of consumers’ promotion strategies on the effectiveness of promotional campaigns for subscribing to Over-the-Top (OTT) streaming services, from a prospective theoretical perspective. Additionally, it explores the moderating effects of platform type and subscriber type on promotion strategies in the context of OTT streaming services.Design/methodology/approachThis study employs an experimental design to separately examine the promotion strategies of subscribers. The first part investigates the effect of promotion strategies on promotional effectiveness, regardless of platform and subscriber types, while the second part considers the moderating effects of both platform type and subscriber type on promotional effectiveness.FindingsThe analysis reveals that renewed subscribers exhibit a positive attitude toward incremental promotions and have stronger intentions to subscribe and recommend. Nonrenewed subscribers, in contrast, prefer discount promotions, demonstrating a positive attitude toward them and expressing higher intentions to subscribe and recommend.Originality/valueThis study applies prospect theory to OTT promotion strategies, uncovers the psychological drivers behind promotion effectiveness and examines the moderating role of subscriber type and platform type, thereby providing actionable insights to improve consumers’ attitudes and behavioral intentions.
Music streaming app service quality (MSASQ) scale: service quality dimensions for music streaming apps
Authors: Singharia Komal , Gupta Garima 
Published: February 2025

Purpose The global music industry has witnessed a tumultuous development in recent years with the emergence of music streaming services (MSSs) which played a pivotal role in rescuing the industry from persistent losses caused by piracy. MSSs are predominantly accessed via mobile applications making it imperative for the music streaming service providers (MSSPs) to focus on enhancing their app-based service quality. Furthermore, the sphere of music streaming has received only limited attention in research thus far, and to address this research void, this study contributes to the existing body of literature by introducing a scale to measure the service quality of music streaming apps, i.e. the MSASQ scale.Design/methodology/approach A mixed-method approach encompassing both qualitative as well as quantitative research techniques involving two-stage data collection was adopted. Items for the scale were collected via secondary (reports, articles, customer reviews, etc.) as well as primary sources (focus groups and interviews). The scale was tested on a sample of 1,129 Music Streaming App (MSA) users for reliability and validity.Findings A multidimensional MSASQ scale with 36 items measuring nine dimensions (hedonic quality, efficiency, user interface content, customer support, personalisation, ease of use, privacy/security and quality of ad exposure) was developed and validated.Originality/value The research endeavours to explore new perspectives on service quality within the music streaming industry, particularly in relation to the freemium model.
Inbound open innovation in construction firms: intellectual capital antecedents and performance consequences
Authors: Nduro Edmund , Duodu Bismark 
Published: February 2025

PurposeThe present study explored the interrelationships between intellectual capital (IC) dimensions, inbound open innovation (IOI) and construction firm performance.Design/methodology/approachA quantitative approach was chosen for this study. Data were collected from 130 construction firms in Ghana using survey questionnaires. Partial least squares structural equation modelling was employed to test the hypotheses of the study.FindingsThe results indicate that while human capital and structural capital both have direct effects on IOI, relational capital does not. IOI positively influences firm performance (FP) linearly but shows a curvilinear (inverted U-shaped) relationship with FP at higher levels of IOI. IOI has a partial mediating effect in the relationships between human or structural capital and FP but does not show any mediation between relational capital and FP.Originality/valueTo the best of the authors’ knowledge, this study is among the first to explore the influence of inbound open innovation on the performance of project-based firms, such as construction, as well as the role of inbound open innovation as a mediator between firms’ intellectual capital and performance in the general management and the construction management literature.
The impact of audit quality on the CO2 emissions: empirical evidence from European companies
Authors: Akermi Abir , Ben Amar Anis 
Published: February 2025

PurposeThe objective of this research is to investigate the impact of audit quality on CO2 disclosure in European companies. This article aims to understand how attributes of audit quality, such as auditor effort, auditor permanence and auditor independence, influence the disclosure of CO2 emissions.Design/methodology/approachA multiple regression analysis on panel data was used. In addition, we applied the fixed effect approach as the optimal and most appropriate model for our main regression. In addition, to control the potential endogeneity problem and to analyse the study data in depth, we used the two-stage Heckman model, the two-stage least squares (2SLS) model, and the generalised method of moments (GMM).FindingsThe results clearly show that all the explanatory variables in the study model have a significant influence on CO2 disclosure. Furthermore, the results show a positive effect of auditor effort on the level of CO2 disclosure. However, auditor tenure and auditor independence negatively affect CO2 disclosure.Originality/valueThis study provides empirical evidence of the role of different audit quality proxies on corporate CO2 disclosure, which has been mainly neglected by previous studies and has not yet been examined by previous researchers. Thus, in order to provide an in-depth understanding of this emerging and unprecedented idea, this study fills this research gap and makes a practical and theoretical contribution to the existing literature on corporate governance and environmental disclosure.
Unfolding knowledge sabotage: the roles of knowledge-sharing climate, trustful climate and dark triad
Authors: Islam Talat , Ali Hafiz Fawad , Abdullah Haldy 
Published: February 2025

Purpose
Knowledge sabotage is an emerging challenge for today’s managers because every second individual is found to be involved in such behaviors. Therefore, to understand the antecedents and consequences of knowledge sabotage, this study aims to investigate the trustful climate toward knowledge-sharing climate through knowledge sabotage. It further investigates the conditional role of destructive personality types in the relationship between trustful climate and knowledge sabotage.

Design/methodology/approach
In this quantitative study, the data from 307 employees and their immediate supervisors working in the IT sector of Pakistan were collected on convenience basis. Furthermore, structural equation modeling and hierarchical regression techniques were applied to test the hypotheses.

Findings
The findings revealed that individuals’ perception of a trustful climate positively contributes to knowledge-sharing climate, and knowledge sabotage intervenes this relationship. Furthermore, the dark triad (psychopathy, narcissism and Machiavellianism) was noted to moderate the association between trustful climate and knowledge sabotage such that the dark triad strengthens this negative association.

Research limitations/implications
This study suggests using peer/colleagues’ rated scales to measure destructive personality. However, the findings suggest managers involve employees in the decision-making process and work on their skills to develop their trust in organizations and involve knowledge sharing. Conversely, managers are suggested to arrange training/workshops for individuals to understand and overcome their negative personality traits.

Originality/value
Contributing to the novel literature on the most extreme form of counterproductive behavior in the field of knowledge management (i.e. knowledge sabotage), this study, to the best of the authors’ knowledge, is the first of its kind that empirically investigates the conditional role of destructive personalities toward knowledge sabotage in the presence of trustful climate.
Conceptualising (corporate) governance in state-owned enterprises: a research agenda
Authors: Adebayo Adeyemi 
Published: February 2025

Purpose
This paper aims to formulate a research agenda by developing a conceptual framework for studying and mitigating corporate governance issues in state-owned enterprises (SOEs), considering pertinent management theories and theories of the firm as described in the contemporary academic discourse on SOEs.

Design/methodology/approach
The authors commenced broadly with the traditional narrative review method to understand the field of corporate governance in SOEs in line with subject matter knowledge. The authors carefully identified studies on corporate governance of SOEs and read them, noting and following relevant citations. The authors then proceed with a more methodical (qualitative) systematic literature review (QSLR) process, selecting more explicit articles and taking advantage of the complementarity of narrative and QSLR methods.

Findings
The review identifies seven pertinent theories in the organisational field of SOEs and describes five of the seven theories that must be conceptualised in examining corporate governance issues in SOEs. Following the description of the theories, this paper suggests a novel strategy for minimising corporate governance issues in SOEs by bringing together corporate governance problems in SOEs and offering insights into how the management theories and the theories of the firm may be applied in studying and mitigating corporate governance problems in SOEs, considering their practices and characteristics.

Practical implications
This review paper responds to calls for further research into public entrepreneurship and elaborates theories applicable to studying corporate governance in SOEs. This involves navigating through SOEs literature, focusing on theories and how they might be conceptualised to explore corporate governance issues in SOEs. This represents the largest research convergence on SOEs, given that various corporate governance challenges typically face SOEs worldwide.

Originality/value
The review offers guidance on applying theories to understand corporate governance challenges in SOEs, particularly using the identified theories in specific corporate governance problem areas. This study appears to be one of the only ones on this topic. Thus, the propositions put forth suggest that the conceptualisation of corporate governance in SOEs in this paper adds value for academics, practitioners and policymaker observers.
Remote onboarding of new employees: a four­-component perspective of welcoming
Authors: Weilage Christopher 
Published: February 2025

Purpose
As technology usage rises and organizations increasingly adopt remote work, remote onboarding has emerged as a critical area requiring deeper exploration. This study aims to explore the affective commitment and engagement of employees who underwent remote onboarding in various industries across Germany. By addressing this gap, the research proposes an enhanced onboarding framework tailored to remote settings.

Design/methodology/approach
This study was designed as exploratory qualitative research from interviews with five participants employed across Germany. The research framework is the onboarding model by Cesário and Chambel (2019), and the model was applied to remote onboarding.

Findings
This study reveals a critical gap in existing onboarding frameworks: the absence of a dedicated IT welcome as a core component of remote onboarding. Participant narratives highlighted challenges with IT-based issues, stemming from IT department contact and access, as impacting commitment and engagement.

Originality/value
This study contributes to the field of remote onboarding by introducing a novel perspective that extends Cesário and Chambel’s (2019) three-component onboarding model. Unlike traditional onboarding studies that emphasize social and organizational integration, this study highlights IT department value to new hire engagement and commitment in digital work environments.
Unveiling opportunities and obstacles in emerging markets: analysis of women’s home-based enterprises using Delphi-DEMATEL approach
Authors: Sabary Gul Shah , Ključnikov Aleksandr , Asad Arif Ibne , Kloudová Jitka , Ferraris Alberto 
Published: February 2025

Purpose
Female entrepreneurship remains a critical issue around the globe, particularly in developing economies where they confront various challenges during self-employment. This paper aims to investigate essential opportunities and challenges for Afghan women’s home-based enterprises (WHBEs) that may impact the decision of female entrepreneurs to establish a venture.

Design/methodology/approach
The study interviewed women home-based enterprise owners through a predesigned questionnaire to identify the main opportunities and challenges. The Delphi and Decision-Making Trial and Evaluation Laboratory (DEMATEL) approach is employed to analyze casual relationships of the main obstacles confronting WHBEs.

Findings
The findings indicate that women home-based enterprise owners utilize substantial opportunities, such as family support and balancing home and business tasks. Challenges include cause and effect groups, while lack of access to finance, insecurity, social restrictions and limited access to digital platforms belong to the cause group. Notably, limited markets, lack of professional knowledge and legal limits have links with the effect group. However, among the identified challenges, legal restrictions remain the highest obstacle, while the lack of access to finance is the lowest challenge in women’s home-based enterprise context.

Research limitations/implications
The cultural and legal barriers that still exist in Afghanistan have made it difficult for researchers to contact female entrepreneurs.

Originality/value
This study fills the gap in investigating casual relationships in an under-researched stream of disadvantaged entrepreneurship, i.e. the WHBE context of female entrepreneurship. It generates value for researchers interested in female entrepreneurship and international organizations that empower women and promote gender equality in developing economies.
Unlocking the potential of small-scale irrigation for small farmers in Northwestern Ethiopia
Authors: Gebrehiwet Dessie Lebassi , Pandey Ghanshyam 
Published: February 2025

PurposeThe main purpose of this study is to assess the impact of small-scale irrigation on the total income of small farm households. Additionally, it aims to identify the factors influencing the total income of households who have adopted small-scale irrigation methods.Design/methodology/approachThe study utilized cross-sectional data sourced directly from primary channels. Primary data collection was facilitated through the administration of semi-structured questionnaires and conducting in-depth interviews. Both propensity score matching (PSM) and an ordinary least squares (OLS) model were employed to assess the impact of small-scale irrigation on total income and to identify factors affecting the effectiveness of SSI. In order to ensure that the PSM model’s findings were consistent, we used instrumental variables (IV) estimation, which was conducted using two stages least squares (2SLS) regression.FindingsThe study findings reveal that small-scale irrigation adopters earn, on average, 12,947.32 Birr more than non-adopters. The PSM model reveals that households engaged in small-scale irrigation experience a significant increase in total income compared to non-irrigating households. The study underscores the need to address key factors influencing the treatment effect on household income, including distance to farm training centers, proximity to water sources, access to transportation, availability of family labor and frequency of extension contact.Research limitations/implicationsThis paper only examines the effect of small-scale irrigation on small farm households’ total income. This study encourages future studies to investigate the effects of small-scale irrigation on small farm household food security, total spending, poverty reduction, welfare and net earnings in the study area.Originality/valueMost studies only analyze how small-scale irrigation affects the total income of small-scale farm households. This study fills a knowledge gap by identifying the key elements that influence the extent of the impact on user households.
