Curved-edge vertex models and increased tissue fluidity
Authors: Staddon Michael F. , Modes Carl D. 
Published: February 2025

The vertex model for epithelia models the apical surface of a tissue by a tiling, with polygons representing cells and edges representing cell-cell junctions. The mechanics are described by an energy governed by deviations from a target area and target perimeter for each cell. It has been shown that the target perimeter p0 governs a solid-to-fluid phase transition: when the target perimeter is low, there is an energy barrier to rearrangement, and when it is high, cells may rearrange for free and the tissue can flow like a liquid. One simplification often made is modeling junctions using straight edges. However, the Young-Laplace equation states that interfaces should be circular arcs, with the curvature being equal to the pressure difference between the neighboring cells divided by the interfacial tension. Here, we investigate how including curved edges alters the mechanical properties of the vertex model and the equilibrium shape of individual cells. Importantly, we show how curved edges shift the solid-to-fluid transition point, from p0=3.81 to p0=3.73, allowing tissues to fluidize sooner than in the traditional model with straight edges.

Opening the black box of entrepreneurial team conflict: how does entrepreneurial team conflict affect entrepreneurial performance?
Authors: Li Bao , Chen Wanming , He Changqing , Xu Yongli , Liu Chunyan 
Published: February 2025

Purpose
Compared to the occurrence of conflict in general teams in organizations, conflict occurrence in entrepreneurial teams is more prevalent and intense. However, previous studies have found inconsistent relationships between entrepreneurial team conflict and performance, and the mechanisms underlying this relationship remain in the “black box.” Drawing on the motivated information processing in groups theory, this study aims to investigate how and when entrepreneurial team conflict influences entrepreneurial performance.

Design/methodology/approach
The authors collected survey data from 190 entrepreneurs across 58 entrepreneurial teams in China. The hypothesized relationships were examined through path analysis using the Mplus7.0 program.

Findings
Entrepreneurial team relationship conflict is negatively related to entrepreneurial performance mediated through team behavioral integration. Conversely, there exists a curvilinear (U-shaped) relationship between entrepreneurial team task conflict and entrepreneurial performance, also mediated through team behavioral integration. Furthermore, the curvilinear relationship between entrepreneurial team task conflict and team behavioral integration is strengthened by team contractual governance, whereas the relationship between entrepreneurial team relationship conflict and team behavioral integration is not moderated by team contractual governance.

Originality/value
This study contributes to a deeper understanding of the relationship between entrepreneurial team conflict and performance by identifying the mediating mechanism and boundary condition. The finding of a U-shaped relationship between entrepreneurial team task conflict and entrepreneurial performance underscores the uniqueness of the entrepreneurial team context, offering new empirical insights for future conflict research.
Do camouflage signals impact performance in reward-based crowdfunding?
Authors: Arroteia Nuno , Bhatta Bibek , Quinn Martin 
Published: February 2025

PurposeReward-based crowdfunding is vital for entrepreneurs who cannot raise funds, but the failure rate to meet funding goals in reward-based crowdfunding is high. Consequently, entrepreneurs try to get backers’ attention and persuade them to pledge funds for their campaigns. Entrepreneurs can provide misleading information in their crowdfunding campaign descriptions, distorting the signals sent to backers. This paper examines how camouflage signals mitigate information asymmetry and its impact on the fundraising ability in reward-based crowdfunding.Design/methodology/approachThe study examines Kickstarter crowdfunding campaigns (n = 100,522) using six established dictionaries for linguistic hedging as proxies for camouflage signals.FindingsThe results reveal a significant and varied impact of camouflage signals on mitigating information asymmetry and, consequently, on the performance of crowdfunding campaigns; these findings are robust to alternative, independent variables and different econometric techniques.Originality/valueThis study contributes to signalling theory literature through its novel study of camouflage signals. It also contributes to the reward-based crowdfunding literature and provides new insights into how camouflage signals mitigate information asymmetry, thereby persuading or deterring backers from pledging funds.
Leveraging platform-based technologies to mitigate product returns in E-commerce: an affordance actualization perspective
Authors: Zhou Yang , Li Huifang , Yin Pengzhen 
Published: February 2025

PurposeThis study investigates how online sellers can leverage platform-based technologies to mitigate product returns through the lens of affordance actualization theory. We conceptualize four categories of platform-based technologies and theorize how their affordances influence consumer perceptions and behaviors, leading to reduced return rates.Design/methodology/approachWe develop a research model grounded in affordance actualization theory and test our hypotheses using a unique longitudinal dataset from a leading e-commerce platform. We employ panel data analysis with seller fixed effects and conduct various robustness checks to ensure the reliability of our findings. We also examine the synergistic effects among different platform-based technologies and explore their varying impacts across product types and seller characteristics.FindingsThe strategic actualization of pricing, marketing, product presentation and customer service technology affordances significantly reduces product return rates. The return-mitigating effects are stronger for low-reputation sellers and high-price, high-complexity products, highlighting the contingent value of technology affordances in managing returns. Besides, we find evidence of synergistic effects among different platform-based technologies, particularly for complex products and less reputable sellers.Originality/valueThis study extends affordance actualization theory to the e-commerce context and uncovers the mechanisms and boundary conditions for platform-based technologies to mitigate product returns. We contribute to the literature by offering a novel theoretical perspective and granular insights into the role of technology in shaping a critical operational outcome in online retailing.
Stigma within families: impact of parental attitudes on youth’s mental health
Authors: Ranwa Ruchika , Arora Richa 
Published: February 2025

Purpose
This paper aims to explore the experiences of mental health-related stigma among youth in Dubai, United Arab Emirates, particularly emerging in the context of families through parental attitudes. Although the existing research has focused on families as victim or recipient of stigma related to mental health, the role of families in perpetuating this stigma remains under-researched. This study investigates origins of such stigma operating within families and its impact on youth.

Design/methodology/approach
Semi-structured interviews were conducted with 40 youth participants in Dubai. Thematic analysis was used as method of analysis.

Findings
Findings show that parental attitudes or beliefs towards mental health are predominantly stigmatizing in nature that discourages disclosure and open dialogue among youth and renders them vulnerable to self-stigmatization. Stigma internalized by the youth manifests in the form of their low self-worth, negative self-perception and worsening their mental health challenges.

Originality/value
This paper contributes to nuanced understanding of stigma operating in informal settings such as families and establishes family as a site of intervention to mitigate stigma towards mental health of youth in early stages.
Factors influencing property valuation models development and application as decision support systems
Authors: Kasim Iddrisu , Amidu Abdul-Rasheed , Levy Deborah 
Published: February 2025

PurposeThere is a shift in the traditional professional practice approaches to information search and processing. As a result, this review paper examines emerging property valuation models in property literature and the factors affecting their application in professional practice. It advocates for a new or extended paradigm for developing models that align with industry regulations.Design/methodology/approachA scoping review approach was adopted to explore property valuation models, the factors influencing their development and their application in professional practice. We summarise the extant literature to understand the concepts, current debates and research trends. A snowball technique using an author citation search was undertaken to ensure that relevant studies were not excluded.FindingsThe findings indicate that challenges in decision-making with traditional valuation methods have led to the creation of advanced valuation models and spatial/database systems. However, technological challenges have hindered the adoption and implementation of these advanced valuation approaches. The study also points out an overemphasis on model development in current property research, neglecting impact assessment and widening the research-practice gap in the property sector.Originality/valueThis study underscores the need for impact analysis to understand the challenges in adopting and engaging with property innovations. We recommend developing industry-specific advanced property valuation models collaboratively through research–practice partnerships. This collaborative approach would help align advanced property valuation models with existing regulations, established standards and practices, ultimately facilitating the institutionalisation and normalisation of innovations within the property industry.

A structured literature review identified leadership competencies relevant to the AI era. Three scientific databases were included in the search: (I) Scopus, (II) EBSCO Business Source Complete, and (III) Web of Science. A total of 730 articles were identified from the three databases under the topics “Digital Leadership,” “Leadership” AND “Artificial Intelligence,” “Future Leadership,” “Algorithm Leadership,” “AI Leadership,” “Artificial Leadership,” and “Data-driven Leadership.”

Findings
A total of 24 leadership competencies, including 12 personality traits and 12 skills, were identified from the literature. To adapt effectively to AI, leaders should focus on developing communication skills and forming high-performance teams working cross-functionally and in a symbiosis of humans and machines.

Originality/value
The article adds knowledge to leadership theories and provides a basis for future management education.
Children's Risky Play and Resilience: Perspectives of Emergency Care Practitioners
Authors: Bauer Michelle E. E. , Cunningham Laura , Gilley Meghan , Pike Ian 
Published: February 2025

ABSTRACTBackgroundParents' perspectives on children's risky play can provide researchers with insight into their injury prevention and safety needs and support researchers in understanding how challenging and exciting play may positively shape children's physical, cognitive, and social development. To date, however, the perspectives of parents who witness severe injuries as part of occupational experiences, and who have medical training, are lacking within this scholarship. In this study, we worked with emergency room practitioners to understand their perspectives on children's risky play and resilience.MethodsA risk and sociocultural theoretical lens informed our approach and we conducted semi‐structured interviews with doctors and nurses (n = 56) across Canada who had children between the ages of 4 and 13.ResultsFindings from a thematic analysis were threefold: (1) learning to persevere through failure, (2) developing distress tolerance, and (3) supporting child autonomy and independence.ConclusionFindings indicate doctors and nurses can perceive children as more emotionally and physically equipped to cope with stressful and potentially injurious situations across their lifespan if they are exposed to challenging and exciting play during childhood. Further, while the practitioners believed it was important to intervene in play which could result in children experiencing severe injuries, they believed adults should support children in testing their physical and cognitive boundaries during risky play without adult interference.

AbstractThe Hox gene Sex combs reduced (Scr) is recognized as a key factor in the development of the head and thorax in insects. However, its function in the growth, development and morphogenesis of Gryllus bimaculatus remains poorly understood. This study aimed to explore the function of the Scr gene in G. bimaculatus by using CRISPR/Cas9 technology to generate an Scr gene knock‐out strain. Intercrossing the G0 generation knock‐out individuals with wild‐type individuals yielded the G1 generation to screen the mutant strain. It was found that the knock‐out of the Scr gene had a severe impact on the growth and development of G. bimaculatus, resulting in high mortality and making it difficult to obtain Scr−/− mutants. Therefore, heterozygous individuals (Scr+/−) with 1 bp deleted were obtained for investigation. The results showed that the Scr deletion led to ectopic segment formation in the G0 generation. In the G2 generation, it was observed that stable Scr−/− strains displayed abnormal embryonic development, characterized by enlarged, blackened and lethal eggs during embryogenesis. During the post‐embryonic stage, Scr−/− mutants exhibited abnormalities in body segmentation, particularly in the head‐thorax region, resulting in a dorsal ridge structure. Furthermore, some Scr+/− individuals exhibited a dorsal ridge during the nymphal stage. Notably, this characteristic did not persist into the adult stage. Our findings highlight the distinct but crucial roles of the Scr gene in both embryonic and post‐embryonic growth and development of G. bimaculatus.

Vertical Separation With Split‐Off Under Passive Ownership
Authors: Zhang Chuyuan , Lee Sang‐Ho 
Published: February 2025

ABSTRACTThis study examines a vertical structure model where an integrated firm sells intermediate goods to downstream firms and produces final goods while a rival firm holds partial passive ownership (PPO) of the integrated firm. We investigate the effects of vertical separation with a split‐off under a downstream PPO when the integrated firm competes with both the rival firm and downstream firms in the final goods market. We find that separation decreases input price and final goods production by the split‐offed firm while increases consumer surplus and domestic welfare if the downstream firms are competitive, or when the degree of PPO is not sufficiently low. We also demonstrate that a split‐off under downstream PPO is more profitable but socially undesirable than the other separation types, including split‐off under upstream PPO and spin‐off. Finally, we provide some discussions on the variant scenarios and show that our main findings are robust.

AbstractObjectiveTo compare the temperatures of dogs undergoing laparoscopic ovariectomy with insufflation using heated or nonheated CO2.Study designRandomized controlled trial.AnimalsFifteen female dogs undergoing laparoscopic ovariectomy.MethodsThe animals were randomly distributed into groups: NH—insufflated with nonheated CO2 (n = 8), or H—insufflated with 36.5°C heated CO2 (n = 7). Body weight, anesthetic time, surgical time, insufflation time, initial esophageal temperature, and final temperature were compared.ResultsAll animals completed the study and recovered well from the surgery. The groups had similar values for body weight, age, initial temperature, and anesthetic, surgical, and insufflation times. The final temperature of the H group was 1.1°C higher than the NH group (p = .0026). In the NH group, correlations between final temperature and anesthetic time (p = .016), surgical time (p = .011), and insufflation time (p = .033) were observed. For the H group, no correlations among these parameters were identified.ConclusionCarbon dioxide insufflation ameriorated the temperature reduction during laparoscopic ovariectomy in dogs.Clinical significanceThe results can be applied directly to prevent hypothermia during laparoscopic procedures in dogs.
Molecular piracy in deep-sea hydrothermal vent: phage-plasmid interactions revealed by phage-FISH in
Marinitoga piezophila
Authors: Jin Min , Rouxel Ouafae , Quintin Nadège , Geslin Claire 
Published: February 2025

ABSTRACT

Prokaryotes and mobile genetic elements (MGEs, such as viruses and plasmids) interact extensively, leading to horizontal gene transfer (HGT) and consequent microbial evolution and diversity. However, our knowledge of the interactions between MGEs in deep-sea hydrothermal ecosystems is limited. In this study, we adapted a phage-fluorescence
in situ
hybridization (phage-FISH) approach to visualize and quantify the dynamics of phage–plasmid interactions in an anaerobic, thermophilic deep-sea bacterium,
Marinitoga piezophila
. Notably, our results revealed that plasmid signals were detected in viral particles released from lysed cells, indicating that mitomycin C not only induced plasmid replication but also its packaging into phage particles. Further analysis of the DNA content in purified virions showed that the phage capsids incorporated plasmid DNA even without induction, and the majority of capsids (up to 70%) preferentially packaged plasmid DNA rather than viral DNA after induction. Therefore, this study provided direct evidence of molecular piracy in the deep-sea hydrothermal ecosystem, highlighting the important roles of selfish MGEs in virus–host interactions and HGT in extreme marine environments.

IMPORTANCE

Deep-sea hydrothermal vents are hotspots for microbes. Several studies revealed that virus-mediated horizontal gene transfer (HGT) in deep-sea hydrothermal vent ecosystems may be crucial to the survival and stability of prokaryotes in these extreme environments. However, little is known about the interaction between viruses and other mobile genetic elements (MGEs, such as plasmids), and how their interactions influence virus-mediated HGT in these ecosystems. In this study, we adapted a phage-fluorescence
in situ
hybridization approach to directly monitor the dynamics of phage–plasmid–host interactions at the single-cell level in the
Marinitoga piezophila
model. Interestingly, our results indicate that plasmid DNA could not only be induced by mitomycin C to a great extent but also hijacked viral assembly machinery to facilitate its propagation and spread. Therefore, the data presented here imply that the interaction between the viruses and other MGEs could play profound roles in virus–host interaction and virus-mediated HGT in the deep-sea hydrothermal ecosystem.
