A whole-body atlas of non-graded BMP signaling activity in a sea anemone
Authors: Knabl Paul , Mörsdorf David , Genikhovich Grigory 
Published: July 2024

AbstractBMP signaling is responsible for the second body axis patterning in Bilateria and in the bilaterally symmetric members of the bilaterian sister clade Cnidaria – corals and sea anemones. However, medusozoan cnidarians (jellyfish, hydroids) are radially symmetric, and yet their genomes contain BMP signaling components. This evolutionary conservation suggests that BMP signaling must have other functions not related to axial patterning, which keeps BMP signaling components under selective pressure. To find out what these functions might be, we generated a detailed whole-body atlas of BMP activity in the sea anemoneNematostella. In the adult polyp, we discover an unexpected diversity of domains with BMP signaling activity, which is especially prominent in the head, as well as across the neuro-muscular and reproductive parts of the gastrodermis. In accordance, analysis of two medusozoan species, the true jellyfishAureliaand the box jellyfishTripedalia,revealed similarly broad and diverse BMP activity, supporting the versatile nature of the BMP pathway across anthozoan and medusozoan Cnidaria.
Tunnel transport problem for open multilayer nitride nanostructures with an applied constant magnetic field and time-dependent potential: An exact solution
Authors: Boyko Igor , Petryk Mykaylo , Lebovka Nikolai 
Published: July 2024

A quantum mechanical theory for description of electronic quasistationary states in two-dimensional (2D) layered semiconductor nanostructure was developed. A constant external magnetic field B was directed along semiconductor layers. The presence of internal electric fields F originated from the potential barriers and wells in semiconductor layers was taken into account. The vector of F was directed perpendicularly to semiconductor layers. The interaction of tunneled electrons with a time-dependent electromagnetic fields was analyzed in detail. An approach to obtain an exact solution to the problem based on a combination of the Lewis-Riesenfeld method for complete Schrödinger equation and scattering theory was developed. Application of the scattering theory in combination with the -matrix and transfer-matrix methods allowed us to calculate the electron quasistationary spectra. Effects of magnetic field on the resonant energy and width of electronic quasistationary states as well as on the electronic conductivity were also discussed.

In many instances online learners have been subjected to learning and teaching designed for the classroom – learning that is designed for a very different delivery mode, one in which space and place have a significantly different impact on learning, and where connectedness with teaching staff and other students is assumed.

Findings
No findings as this is a viewpoint paper.

Research limitations/implications
No research implications as this is a viewpoint paper.

Practical implications
This paper has practical implications for learning designers and those involved in the design and development of online learning events.

Engaging long-tenured employees via high-performance work systems: a matter of dosages
Authors: Stirpe Luigi , Revilla Antonio J. 
Published: July 2024

PurposeWe investigate the engagement benefits of high-performance work systems (HPWS) for long-tenured employees compared with short-tenured ones. Using a social exchange lens and building upon hedonic adaptation research, we propose that HPWS are less effective for engaging longer tenured employees, unless they are administered at high levels.Design/methodology/approachMultiple regression and post-estimation analyses of marginal effects on a sample of 30,375 employees, based on data from the 6th European Working Conditions Survey.Findings(1) Employee tenure negatively moderates the HPWS-engagement relationship; (2) this effect is contingent on the level of HPWS, with long-tenured employees responding comparatively better than short-tenured ones to exposure to high levels of HPWS; (3) HPWS have decreasing marginal effects on engagement—greater exposure to these systems does not linearly translate into higher employee engagement, with their decreasing returns being more noticeable for short- than long-tenured employees.Originality/valueThe study provides novel insights into the value of HPWS as motivational tools and advises managers to promote tenure-differentiated HPWS investments. It also illuminates critical issues related to the sustainability of HPWS.
The cell-centered positivity-preserving finite volume scheme for 3D convection–diffusion equation on distorted meshes
Authors: Peng Gang 
Published: July 2024

PurposeThis paper aims to construct positivity-preserving finite volume schemes for the three-dimensional convection–diffusion equation that are applicable to arbitrary polyhedral grids.Design/methodology/approachThe cell vertices are used to define the auxiliary unknowns, and the primary unknowns are defined at cell centers. The diffusion flux is discretized by the classical nonlinear two-point flux approximation. To ensure the fully discrete scheme has positivity-preserving property, an improved discretization method for the convection flux was presented. Besides, a new positivity-preserving vertex interpolation method is derived from the linear reconstruction in the discretization of convection flux. Moreover, the Picard iteration method may have slow convergence in solving the nonlinear system. Thus, the Anderson acceleration of Picard iteration method is used to solve the nonlinear system. A condition number monitor of matrix is employed in the Anderson acceleration method to achieve better robustness.FindingsThe new scheme is applicable to arbitrary polyhedral grids and has a second-order accuracy. The results of numerical experiments also confirm the positivity-preserving of the discretization scheme.Originality/value1. This article presents a new positivity-preserving finite volume scheme for the 3D convection–diffusion equation. 2. The new discretization scheme of convection flux is constructed. 3. A new second-order interpolation algorithm is given to eliminate the auxiliary unknowns in flux expressions. 4. An improved Anderson acceleration method is applied to accelerate the convergence of Picard iterations. 5. This scheme can solve the convection–diffusion equation on the distorted meshes with second-order accuracy.
The mediating effect of team trust on shared leadership and team performance
Authors: Han Soo Jeoung , Kim Mirim , Beyerlein Michael 
Published: July 2024

PurposeAs team members temporarily assume the role of leader, a system of shared leadership emerges. This study had three purposes: (a) to test the underlying three dimensions of shared leadership behaviors, (b) to examine the relationship between shared leadership behaviors and team performance, and (c) to examine the mediating effect of trust between team members’ perceptions of shared leadership and performance.Design/methodology/approachWe used the sub-dimensions of shared leadership: relation-oriented shared leadership (ROSL), task-oriented shared leadership (TOSL), and creativity-oriented shared leadership (COSL). We collected survey data from college student teams at two different time points.FindingsThis study’s factor analysis results supported a second-order factor model that explains shared leadership with TOSL, ROSL, and a new COSL construct. Additionally, we discovered that shared leadership behaviors predicted team performance both directly and indirectly through team trust.Originality/valueThis study confirms the role of the new sub-dimension of COSL originally discovered by video analysis of project teams (Leight et al., 2018), thereby adding value to shared leadership research. This quantitative study supports the COSL with TOSL and ROSL in a second-order model where each component contributes unique input into the team dynamics. Our findings underscore the significance of shared leadership in elevating team trust, ultimately resulting in improved team performance. This insight holds particular relevance for educational management and leadership, offering a framework for understanding how shared leadership practices can positively influence team dynamics within academic contexts.
Gender-differences in retirement from entrepreneurship: the influence of pension policies across Europe
Authors: Komp-Leukkunen Kathrin 
Published: July 2024

PurposeThe interest in older entrepreneurs increases due to population aging. Previous research showed clear gender-differences among older entrepreneurs. This study investigates whether such gender-differences also exist in the retirement transition from entrepreneurship. It explores the influence of pension regulations for entrepreneurs on these gender-differences.Design/methodology/approachLongitudinal micro-level data from the Survey of Health, Aging and Retirement in Europe is analyzed in multichannel sequence analyses and cluster analyses. Developments from age 50 to 69 are compared in the dimensions of entrepreneurship, employment and old-age pensions.FindingsEntrepreneurs retire in three different transition patterns: (1) entrepreneurs becoming pensioners at 60, (2) entrepreneurs becoming pensioners at 65 and (3) individuals combining entrepreneurship with employment until they become pensioners at 65. Female entrepreneurs follow the same transition patterns as their male counterparts but retire earlier. Pension regulations for entrepreneurs modify the extent of the gender-differences within a country. Mandatory pension schemes with identical state pension ages for men and women reduce gender-differences, whereas mandatory schemes with gender-differences in the state pension age increase them. Schemes without mandatory coverage range in between the other two.Originality/valueThis article expands our knowledge on gender-differences among older entrepreneurs. These gender-differences also extent to how entrepreneurs transition into retirement. Pension regulations for entrepreneurs influence the extent of the gender-differences. Therefore, pension regulations for entrepreneurs constitute tools for promoting or hindering gender equality.

It investigates the impact of uncertainty on digitalization project success and the role of absorptive capacity.Design/methodology/approachA mixed-methods approach is adopted, incorporating qualitative and quantitative analyses. The qualitative part assesses how uncertainty affects digitalization project success, while the quantitative side explores absorptive capacity as a mediating factor between adaptability to uncertainty and project success.FindingsThe qualitative results uncover challenges facing digitalization projects under uncertainty and suggests coping strategies at individual, project, and organizational levels. Quantitative results show that both potential and realized absorptive capacities significantly mediate the link between adaptability to uncertainty in the environment and project success.Originality/valueThis research offers new insights into digitalization project studies, merging organizational learning theory with a mixed-methods approach. It highlights how uncertainty and absorptive capacity influence digitalization project success.
Hybrid strategy and its effect on the market performance of family-business SMEs: the mediating role of innovation
Authors: Gutiérrez-Broncano Santiago , Rubio-Andrés Mercedes , Linuesa Langreo Jorge , Sastre-Castillo Miguel Angel 
Published: July 2024

PurposeFor this paper, the authors focus on Porter’s competitive advantage. Hybrid strategy refers to how a firm creates valuevis-à-viscompetitors by simultaneously relying on lower costs and greater differentiation to achieve a competitive advantage. This strategy emphasises both and aims to provide much more monetary value to customers through the combination of reduced cost and a higher rate of differentiation. In addition, this research focuses on family small and medium-sized enterprises (SMEs), because they have particularities arising from the incorporation of family members both as owners of the SME and in managerial positions. The porpose of this study is to analyse whether the existing differences produced by the role of the family in strategic decision-making and the concentration of family power have a higher impact on performance and innovation than non-family SMEs.Design/methodology/approachStructural equation modelling was used to analyse Spanish firms with fewer than 250 employees. This study randomly selected SMEs operating in Spain from the Spanish Central Business Directory (2021) database. The overall sample design was based on stratified sampling.FindingsSMEs are facing new challenges, and this has led to the emergence of new competitive strategies. Companies have started to combine differentiation strategies with cost strategies to achieve superior performance and better adapt to these changes. This study confirms a positive relationship between the adoption of hybrid strategies and market performance in SMEs. In addition, hybrid strategy reinforces innovation, which has a mediating role between hybrid strategy and market performance. Finally, the findings indicate that family SMEs achieve a greater impact of hybrid strategy on innovation than non-family SMEs. Moreover, innovation plays a mediating role only in the case of family firms, which enhances the relationship between hybrid strategy and market performance.Originality/valueFor SMEs to survive in turbulent environments, this study proposes the adoption of hybrid strategies instead of pure strategies. The novel model links hybrid strategy (as opposed to “stuck in the middle”), innovation and market performance. The research is valuable for owners and managers of family SMEs because this study finds differences in the relationships studied compared to non-family SMEs.
Capturing innovation orientation in knowledge workers: development and validation of a measurement scale
Authors: Thomas Asha , Khatri Puja , Dabas Vidushi , Coniglio Ilda Maria 
Published: July 2024

Purpose
Competition in the modern, knowledge-based economy is utterly pendant on innovation, rendering it indispensable in virtually every organisation. Knowledge workers, therefore, must remain vigilant, spanning novel ways to innovate. Given the relevance of innovation orientation (IO) in knowledge work, it is imperative to possess an extensive understanding of the concept. Therefore, this study aims to develop and validate a measurement scale to gauge employees’ IO.

Design/methodology/approach
Considering that the instruments now in existence exhibit insufficiency for measuring knowledge workers’ IO in its entirety, the mixed-method approach used in this study draws on both qualitative and quantitative findings across various studies, to address this problem. This study has been organised into five stages: item generation, scale purification, scale refinement, nomological validation and generalizability.

Findings
This study establishes and verifies a second-order, reflective–reflective IO measure founded on multiple samples, encompassing the dimensions of creative orientation, learning orientation, first-mover orientation, trust orientation and agility orientation. The resultant IO scale serves as a robust and reliable tool that is capable of being leveraged to explain, assess and enhance IO for knowledge workers.

Research limitations/implications
The rigorous methodology used in this scale development procedure serves as a benchmark for prospective scale development methodologists. From a managerial stance, this study serves managers/leaders concerning how to foster an innovation-oriented work environment to uncover employees’ hidden innovators. Organisations can leverage this study to discover, cultivate and capitalise on knowledge workers’ IO.

Originality/value
Although there exists an abundance of research on IO viewed from an institutional standpoint, research centred on the IO of knowledge workers is scarce. To bridge this gap, this study has developed and validated a scale for measuring knowledge workers’ IO.
The role of freight forwarding companies in detecting and investigating trade-based money laundering
Authors: Makkink Ilse Maritha , Steyn Blanche , Bezuidenhout Hannes Christo 
Published: July 2024

Purpose
This study aims to investigate the role of freight forwarding companies in detecting and reporting trade-based money laundering. The proximity of freight forwarding companies to shipping-related trade-based money laundering red flags places them in an ideal position to detect suspicious transactions.

Design/methodology/approach
The study used semi-structured interviews with expert participants in freight forwarding shipping and compliance aspects around freight forwarding. This study focuses on the South African context.

Findings
Freight forwarding companies are well-positioned to detect, investigate and report on trade-based money laundering schemes. However, the companies are not always aware of the guidelines designed to assist in identifying trade-based money laundering schemes. Thus, freight forwarding companies develop internal processes to identify trade anomalies but are often unable to link trade anomalies to illegal financial flows and trade-based money laundering schemes.

Research limitations/implications
The current regulations on money laundering can be extended to freight forwarding companies by the respective regulators for enhanced anti-money laundering protection. This study is limited to freight forwarding companies in a South African context.

Practical implications
Increased awareness among staff in freight forwarding companies can assist them in identifying trade-based money laundering red flags to detect and prevent trade-based money laundering schemes.

Social implications
This paper assists other role players and policymakers in the trade process to create a better awareness of trade-based money laundering. The limited obligations on freight forwarding companies to comply with anti-money laundering regulations lead to a more volunteer-like compliance practice.

Originality/value
To the best of the authors’ knowledge, this is the first paper that offers insight into the role of freight forwarding companies in detecting trade-based money laundering in South Africa.
Stakeholder assessment of design quality indicators for community centers: a Delphi approach
Authors: Hassanain Mohammad A. , Al-Suwaiti Ibrahim 
Published: July 2024

PurposeThis paper seeks to establish design quality indicators (DQIs) that can be utilized for assessing the design of community centers, with an emphasis on the technical, functional, and behavioral performance domains.Design/methodology/approachA comprehensive literature review resulted in identifying 79 DQIs for community centers. A three round Delphi evaluation approach was utilized to rate the importance of the DQIs through their relative importance index (RII) values. The assessment of the DQIs involved a diverse group of stakeholders including facilities managers, architects/engineers (A/Es), community centers’ staff, and regular visitors of community centers.FindingsThe majority of the established DQIs were considered to be either “Very Important” or “Important”.Practical implicationsThe established DQIs can be utilized to identify best practices in the design of community centers and benchmark the performance of different community centers.Originality/valueThe design quality of community centers could significantly impact the community's quality of life and user experience. The development of DQIs provides for enhanced accountability and improved service delivery for the communities they serve. This enables community centers to be more effective, efficient, and responsive to the needs of the users they support.

Authors: Dutta Sabita , Dixit Saumya , Khare Arpita 
Published: July 2024

Purpose
Understanding tourist experiences with virtual reality (VR) products is essential for firms using VR for tourism marketing, particularly in developing countries where customers do not have access to personal VR devices or gadgets. This study aims to provide insights into technology usage for tourism marketing India, which is a developing country. It explores 360° virtual tours as an upcoming strategy for tourism promotion by analysing tourists’ perspectives through a qualitative approach.

Design/methodology/approach
360° YouTube video launched by the Ministry of Tourism, Government of India, was shown to the participants as a marketing stimulus, followed by questions to understand tourists’ experiences and intentions. Responses were collected from 45 tourists who visited popular tourist destinations such as Shimla, Manali and Dharamshala districts of Himachal Pradesh, India.

Findings
The findings of the study indicate that several crucial elements play a pivotal role in creating the 360° VR experience. Based on interviews, it was found that 360° video experiences assist in visualising a destination through imaginative exploration, generating curiosity about the destination, forming a favourable image of the destination and facilitates ease of experience. A few participants mentioned experiencing discomforts, such as motion sickness and eye strain, while viewing 360° videos. Moreover, tourists provided valuable insights into various factors, including how 360° videos elicit arousal through entertainment and excitement, develop immersion and engagement in the virtual environment (VE), aid in assessing destination suitability, offers advantage over other media, serves as a substitutes for travel during constraints, generates assurance and influences intentions. These factors have emerged as significant considerations influencing their willingness to adopt such technology in the future.

Originality/value
In the contemporary market landscape, 360° VR technology is anticipated to enhance the experiential elements within VEs. While existing research has focused on the technical attributes of VR, there remains a crucial gap pertaining to the experiential and destination-related elements and their influence on usage, travel planning and intentions. Therefore, this study provides deeper insights into the unexplored concepts and dimensions of the virtual tourism experience, particularly concerning interaction with 360° videos. The study contributes novel insights to the existing body of tourism literature and provides practical implications for enhancing 360° virtual tour experiences.
