ABSTRACTThe molecular programs that drive proliferation and differentiation of intestinal stem cells (ISCs) are essential for organismal fitness. Notch signalling regulates the binary fate decision of ISCs, favouring enterocyte commitment when Notch activity is high and enteroendocrine cell (EE) fate when activity is low. However, the gene regulatory mechanisms that underlie this process on an organ scale remain poorly understood. Here, we find that the expression of the C2H2-type zinc-finger transcription factorChronophage(Cph), homologous to mammalian BCL11, increases specifically along the ISC-to-EE lineage when Notch is inactivated. We show that the expression ofCphis regulated by the Achaete-Scute Complex (AS-C) gene,scute,which directly binds to multiple sites within theCphlocus to promote its expression. Our genetic and single-cell RNA sequencing experiments demonstrate that Cph maintains the ISC and EE populations and is necessary to remodel the transcriptome of progenitor cells with low Notch activity. By identifying and functionally validating Cph target genes, we uncover a novel role forsugar free frosting(sff) in directing proliferative and lineage commitment steps of ISCs. Our results shed light on the mechanisms by whichCphsustains intestinal epithelial homeostasis and could represent a conserved strategy for balancing proliferation and differentiation in different tissues and species.
Nonuniversality of heavy quark hadronization in elementary high-energy collisions
Authors: Dai Yuxuan , Zhao Shouxing , He Min 
Published: September 2024

It has been traditionally hypothesized that the heavy quark (charm c and bottom b) fragmentation is universal across different collision systems, based on the notion that hadronization as a soft process should occur at the characteristic nonperturbative quantum chromodynamics (QCD) scale, ΛQCD. However, this universality hypothesis has recently been challenged by the observation that the c- and b-baryon production relative to their meson counterparts in minimum bias proton-proton (pp) collisions at the CERN Large Hadron Collider (LHC) energies is significantly enhanced as compared to the electron-positron (e+e−) collisions. The conception of nonuniversality is unambiguously reinforced by the latest measurement of the charged-particle multiplicity dependence of the b-baryon–to–meson yield ratio, Λb/B, by the LHCb experiment in s=13TeVpp collisions at the LHC, evolving continuously from the saturation value in minimum bias pp collisions toward the small value in e+e− collisions as the system size gradually reduces. We address the multiplicity dependence of b-baryon production in the canonical statistical hadronization model with input b-hadron spectrum augmented with many hitherto unobserved states from quark model predictions. We demonstrate that the decreasing trend of the Λb/B toward low multiplicities can be quantitatively understood from the canonical suppression on the yield of Λb, as caused by the requirement of strict conservation of baryon number in sufficiently small systems. We have therefore proposed a plausible scenario for understanding the origin of the nonuniversality of heavy quark fragmentation in elementary collisions.

After reading and analyzing this case study, students will be able to describe the challenges of creating an electric vehicle (EV) start-up with the objective of zero-carbon emissions, identify opportunities and challenges for Satyadarshan Technologies & Services (STS) in enhancing the B2B customer base and sales volumes in the EV market, identify and assess government incentives to reinforce STS’s existing EV business and compose an understanding of and determine an ability to use various industrial marketing and promotion strategies for STS in the present environment.

Case overview/synopsis
STS was launched in 2020 to provide environmentally conscious urban commuting. Himanshu Purohit, the founder of STS, commenced an e-bicycle assembly unit and produced the first advanced electric drivetrain technology. The vision was to transform how people viewed mobility and make EVs the standard for a healthier globe. Nurturing a start-up with zero-carbon emissions was tedious due to limited infrastructure, high costs, low market acceptance and supply chain constraints. With the relentless pursuit of excellence, STS constantly pushed the boundaries and crossed the break-even ceiling in the year 2022. As a budding player in the souk, the company expected to gain a strong presence in the EV market with particular attention to the B2B customer segment. At the same time, the company aimed to ensure business sustainability by leveraging government incentives. The company needed to expand its corporate sales volume and craft a sustainable competitive advantage. Purohit recognized various challenges to the sustainability of STS that stood between the company's goals and their realization, particularly in achieving a sustainable move in the EV segment. Consequently, Purohit found himself at a critical juncture to pave the path toward the growth of the start-up. Eventually, analysis of the company's business challenges, industrial marketing and promotional strategies required strategic planning to appraise and evaluate the business model.

Numerical study on the behavior of a polymeric MHD nanofluid: entropy optimization and thermal analysis
Authors: Khan Razi 
Published: September 2024

Purpose
Analyzing and reducing entropy generation is useful for enhancing the thermodynamic performance of engineering systems. This study aims to explore how polymers and nanoparticles in the presence of Lorentz forces influence the fluid behavior and heat transfer characteristics to lessen energy loss and entropy generation.

Design/methodology/approach
The dispersion model is initially used to examine the behavior of polymer additives over a magnetized surface. The governing system of partial differential equations (PDEs) is subsequently reduced through the utilization of similarity transformation techniques. Entropy analysis is primarily performed through the implementation of numerical computations on a non-Newtonian polymeric FENE-P model.

Findings
The numerical simulations conducted in the presence of Lorentz forces provide significant insights into the consequences of adding polymers to the base fluid. The findings suggest that such an approach minimizes entropy in the flow region. Through the utilization of polymer-MHD (magnetohydrodynamic) interactions, it is feasible to reduce energy loss and improve the efficiency of the system.

Originality/value
This study’s primary motivation and novelty lie in examining the significance of polymer additives as agents that reduce entropy generation on a magnetic surface. The author looks at how nanofluids affect the development of entropy and the loss of irreversibility. To do this, the author uses the Lorentz force, the Soret effect and the Dufour effect to minimize entropy. The findings contribute to fluid mechanics and thermodynamics by providing valuable insights for engineering systems to increase energy efficiency and conserve resources.
The impact of soft lean practices on business performance: mediating role of customer satisfaction
Authors: Machingura Tinotenda , Muyavu Ashleigh Tatenda , Adetunji Olufemi 
Published: September 2024

Purpose
Many firms have adopted different methodologies such as lean management to increase customer satisfaction. This is because they need to respond to customer demands for improved products and responsive service. This study aims to evaluate the influence of soft lean practices (SLP) on business performance in the service sector.

Design/methodology/approach
Out of 702 questionnaires distributed to various service companies in Zimbabwe, 260 valid responses were received. Structural equation modeling was used to assess the relationship among the factors of the proposed model.

Findings
The implementation of SLP leads to improvement in the business performance of the service companies. However, the impact of SLP on business performance is mainly indirect, mediated by customer satisfaction.

Research limitations/implications
The research focused on the implementation of SLP in the service industry of a developing country; hence, the results obtained may require further investigations before generalization to other countries with different sociocultural contexts is made.

Originality/value
Most previous studies focused mainly on the implementation of the technical lean practices in the manufacturing industry without properly acknowledging the importance of SLP. This research investigates the importance of SLP in the service sector and further explores the mediatory role of customer satisfaction on business performance. The findings also validate the service-profit-chain theory.
Sexual harassment, rape myths and paraphilias in the general population: a mediation analysis study
Authors: Snow Emily , Longpré Nicholas 
Published: September 2024

Purpose
Sexual harassment is a worldwide and prevalent problem that can have severe consequences. The #MeToo movement has highlighted that sexual harassment is not an isolated event and is linked to misogynistic cognitions and other forms of sexual violence. However, there is a lack of research regarding the relationship between sexual harassment and its nomological network, particularly in the general population. Therefore, the purpose of this paper is to explore the nomological network of harassment.

Design/methodology/approach
The aim of this study was to explore the relationship between perception of harassment and rape myths (RMS), with paraphilia (fantasy and behaviour) as mediators. In addition, the prevalence of paraphilia in the general population was explored and gender difference was analysed. Frequencies, Pearson's r correlations, independent sample t-tests and mediation analyses were conducted on a sample of n = 254 participants from the general population.

Findings
Analyses revealed that half of the sample have engaged in at least one paraphilia behaviour. Furthermore, correlations between a more lenient perception of harassment, RM acceptance and paraphilia were found, as well as significant gender differences. Finally, mediation models revealed a strong relationship between RM acceptance and a more lenient perception of harassment, with paraphilia mediating this relationship.

Practical implications
This study has several implications, highlighting the role of misogynistic cognitions in predicting a lenient perception of sexual harassment, and thus, proposing a key focus for prevention and intervention models.

Originality/value
This research is mostly conducted on male samples in these areas; thus, this study aimed to collect data from a diverse sample that may provide a better overview of sexual harassment and its nomological network.
School principals’ resistance to change: a multilevel analysis of individual factors and contextual conditions
Authors: Kalbermatten Cyrill Julian , Ritz Adrian 
Published: September 2024

PurposeThe purpose of this paper is to study the relationship between the attitudes of principals, municipality-specific aspects of reform implementation, and principals’ resistance to change.Design/methodology/approachThe collected data are based on a multi-level structure. The levels of analysis are at the school level (school principal) and at the municipality level. Therefore, the research question posed in this study is examined using a quantitative multi-level analysis.FindingsThe results show that both the personal attitudes of school principals and adjustments made by the school presidency of the municipality affect the school principals’ willingness to change.Research limitations/implicationsThe study’s focus on schools limits the ability to generalize the results to apply to other organizations. Nevertheless, schools are an important object of study for change management research because they share crucial organizational characteristics with other organizations in the public sector.Originality/valueStudies that have looked at the change reactions of leaders in the public school sector have rarely examined individual and collective factors together. We focus on both, since the municipalities in many countries have a certain amount of leeway in implementing reforms, meaning that their involvement is of central importance for a successful change process.
Exploring the role of heuristics in buyer–supplier relationship dynamics
Authors: Åberg Susanne , Andersen Poul Houman 
Published: September 2024

PurposeThis paper aims to explore the role of heuristics in the reassessment of relationship events and how it influences perceptions of commitment, fairness and relationship value. It answers the question of how heuristics interrelate with decision-makers’ evolving interpretations of commitment, fairness and relationship value in a specific buyer-supplier relationship.Design/methodology/approachThis paper presents data from a longitudinal study of an evolving buyer–supplier relationship involving a multinational supplier of fast-moving consumer goods and a medium-sized and highly specialized supplier. It analyzes qualitative data about the use of heuristics in buyer–supplier relationships, and it is based on evidence collected from interviews, presentations, meetings and secondary data.FindingsThis paper shows that a buyer’s unexpected behavior can lead to a reassessment of commitment, fairness and relationship value. Heuristics can delay relationship reassessments, however. The case shows that heuristics have a preserving quality and that the effect of transformative events only slowly changes the perception of the value of the relationship. In this change process, the link between commitment, perceived fairness and heuristics is crucial.Originality/valueThis paper contributes to research on the relationship between buyer–supplier relationships and heuristics. In particular, the paper contributes to the understanding of how relational events in a buyer-supplier relationship change the commitment and perception of fairness, and how heuristics change accordingly. On a more overarching level, the study contributes to our understanding of business relationship dynamics.

Integrated optimization of logistics routing problem considering chance preference
Authors: Ren Liang , Zhou Zerong , Fu Yaping , Liu Ao , Ma Yunfeng 
Published: September 2024

PurposeThis study aims to examine the impact of the decision makers’ risk preference on logistics routing problem, contributing to logistics behavior analysis and route integration optimization under uncertain environment. Due to the unexpected events and complex environment in modern logistics operations, the logistics process is full of uncertainty. Based on the chance function of satisfying the transportation time and cost requirements, this paper focuses on the fourth party logistics routing integrated optimization problem considering the chance preference of decision makers from the perspective of satisfaction.Design/methodology/approachThis study used the quantitative method to investigate the relationship between route decision making and human behavior. The cumulative prospect theory is used to describe the loss, gain and utility function based on confidence levels. A mathematical model and an improved ant colony algorithm are employed to solve the problems. Numerical examples show the effectiveness of the proposed model and algorithm.FindingsThe study’s findings reveal that the dual-population improvement strategy enhances the algorithm’s global search capability and the improved algorithm can solve the risk model quickly, verifying the effectiveness of the improvement method. Moreover, the decision-maker is more sensitive to losses, and the utility obtained when considering decision-makers' risk attitudes is greater than that obtained when the decision-maker exhibits risk neutrality.Practical implicationsIn an uncertain environment, the logistics decision maker’s risk preference directly affects decision making. Different parameter combinations in the proposed model could be set for decision-makers with different risk attitudes to fit their needs more accurately. This could help managers design effective transportation plans and improve service levels. In addition, the improved algorithm can solve the proposed problem quickly, stably and effectively, so as to help the decision maker to make the logistics path decision quickly according to the required confidence level.Originality/valueConsidering the uncertainty in logistics and the risk behavior of decision makers, this paper studies integrated routing problem from the perspective of opportunity preference. Based on the chance function of satisfying the transportation time and cost requirements, a fourth party logistics routing integrated optimization problem model considering the chance preference of decision makers is established. According to the characteristics of the problem, an improved dual-population ant colony algorithm is designed to solve the proposed model. Numerical examples show the effectiveness the proposed methods.

Published: September 2024

Purpose
The purpose of this study is to investigate the relationship between dietary diversity and haemoglobin concentration of women of reproductive age (WRA), 15−49 years in the Binduri District, of the Upper East Region (UER) of Ghana.

Design/methodology/approach
This cross-sectional study was conducted among 153 non-pregnant, non-lactating WRA from three randomly selected communities in the Binduri District of the UER of Ghana. Socio-demographic information, 24-h dietary recall and minimum dietary diversity scores (DDS) of the women were obtained using an interviewer-administered questionnaire. Haemoglobin concentration of the participants was measured by finger prick using Hemocue 301 Analyzer and classified according to WHO standards. Linear regression analysis was used to assess the relationship between DDS and haemoglobin concentrations of the participants.

Findings
Total study participants were 153 with mean age of 32.8 ± 8.7 years. Anaemia prevalence of 66.7% and a mean DDS of 4.0 ± 1.2 was recorded. DDS was found to be a strong predictor of haemoglobin concentration (p = 0.00, R2 = 0.48).

Practical implications
Interventions that increase DDS may be effective in improving haemoglobin levels of WRA.

Originality/value
The results showed that DDS is a strong predictor of haemoglobin concentration of the WRA in this study. As the dietary diversity of the women increased, their mean haemoglobin concentration also improved. To the best of the authors’ knowledge, this is the first study of its kind to be conducted in the study area.
