Authors: Li Ting , Wu Junmiao , Wang Junhai , Yu Yunwu , Li Xinran , Wei Xiaoyi , Zhang Lixiu 
Published: May 2024

Purpose
The purpose of this article is to prepare graphene/polyimide composite materials for use as bearing cage materials, improving the friction and wear performance of bearing cages.

Design/methodology/approach
The oil absorption and discharge tests were conducted to evaluate the oil content properties of the materials, while the mechanical properties were analyzed through cross-sectional morphology examination. Investigation into the tribological behavior and wear mechanisms encompassed characterization and analysis of wear trace morphology in PPI-based materials. Consequently, the influence of varied graphene nanoplatelets (GN) concentrations on the oil content, mechanical and tribological properties of PPI-based materials was elucidated.

Findings
The composites exhibit excellent oil-containing properties due to the increased porosity of PPI-GN composites. The robust formation of covalent bonds between GN and PPI amplifies the adhesive potency of the PPI-GN composites, thereby inducing a substantial enhancement in impact strength. Notably, the PPI-GN composites showed enhanced lubrication properties compared to PPI, which was particularly evident at a GN content of 0.5 Wt.%, as evidenced by the minimization of the average coefficient of friction and the width of the abrasion marks.

Practical implications
This paper includes implications for elucidating the wear mechanism of the polyimide composites under frictional wear conditions and then to guide the optimization of oil content and tribological properties of polyimide bearing cage materials.

Originality/value
In this paper, homogeneously dispersed PPI-GN composites were effectively synthesized by introducing GN into a polyimide matrix through in situ polymerization, and the lubrication mechanism of the PPI composites was compared with that of the PPI-GN composites to illustrate the composites’ superiority.

School leadership and teaching practice: a systematic review of studies of the indirect effects
Authors: Ninković Stefan , Knežević Florić Olivera 
Published: May 2024

PurposeSince teaching practice is the most important within-school determinant of student learning outcomes, a deepened understanding of how and why school leadership contributes to effective teaching is needed. This article aimed to systematically review the knowledge that has been accumulated about the indirect relations between school leadership and instructional practices.Design/methodology/approachThe Preferred Reporting Items for Systematic Reviews and Meta-Analyses guided the selection of relevant articles from the databases Scopus and Google Scholar. Twenty-six published works met the eligibility criteria and were included in the narrative synthesis and content analysis.FindingsThe most frequently measured mediators of the effects of school leadership on teaching practice were teacher collaboration, professional learning and teacher self-efficacy. Most studies simultaneously modeled multiple mediated pathways from school leadership to teaching practice. However, only a few analyzed studies used time lags when examining relationships between constructs.Originality/valueThis is the first study to systematically review knowledge on pathways through which school leadership is related to classroom instruction. Thus, this review provides a comprehensive understanding of processes through which school leadership achieves its effects on instructional practices.
Ethical decision-making: an interactive model of organizations’ ethics systems and decision-makers’ financial situation
Authors: Kportorgbi Holy Kwabla , Aboagye-Otchere Francis , Kwakye Teddy Ossei 
Published: May 2024

Purpose
This study aims to investigate the influence of two perceived organizational ethics systems (perceived ethics training quality and integrity-based climate) on the ethical decision-making (EDM) of tax accountants in Ghana. The study also examines the moderating role of the decision-makers’ financial situation on the quality ethics training–EDM relationship.

Design/methodology/approach
Survey data from 356 tax accountants were analyzed using the partial least squares structural equation modeling technique.

Findings
The results show that the two ethics systems influence EDM, but their extent of influence varies across the stages of EDM. Specifically, quality ethics training is a better predictor of EDM at the ethical issue recognition stage, whereas integrity-based climate is a better predictor of EDM at the ethical intention stage. The study also found that decision-makers’ financial situation predicts the ethical recognition stage of EDM but does not moderate the quality ethics training–EDM relationship.

Practical implications
This study recommends the concurrent deployment of quality ethics training and an integrity-based work climate to improve ethical behavior. Policymakers should also emphasize a work climate that promotes honesty, conscientiousness and ethical principles (integrity-based climate) to improve ethical intentions.

Originality/value
This study applied the interactionist theory by capturing the relative effects of two organizational ethics systems and an individual-level situational factor in a single model. To the best of the authors’ knowledge, this is the first study that tests the moderation effect of decision-makers’ financial situation on the ethics training–EDM relationship in a developing country context.
A globalized symbolic environment ward by the States and dominated by organizations: enticing the nobility and influencing the class habitus
Authors: Borim-de-Souza Rafael , Travis Eric Ford , Zanoni Beatriz Lima , Capucho Pablo Henrique Paschoal , Jan-Chiba Jacques Haruo Fukushigue 
Published: May 2024

Purpose
Through Bourdieusian sociology, this study aims to interpret a globalized symbolic environment ward by the States and dominated by organizations through the States’ Nobilities enticing and the Euro-American influences disseminated by the cultural circuit of capitalism in the inculcation and incorporation of a class habitus conniving with this logic of domination.

Design/methodology/approach
This study has developed a theoretical essay based on the contributions of Bourdieusian sociology to discuss and understand the following concepts and their respective relationships: symbolic environment, globalization, organizations, State, State Nobility, Euro-American influences, cultural circuit of capitalism and class habitus.

Findings
The arguments built throughout this theoretical essay recognized how class habitus on environment contributes to organizations establishing themselves as a space that consolidates and replicates the domination logic. As indicated, the State Nobility is an intermediary element between dominant organizations and the State, as dominated.

Practical implications
This theoretical essay signals that less harmful alliances between organizations, the State Nobility and the State could culminate in social, environmental and economic scenarios provided with more inclusion, diversity and preservation.

Social implications
This study presents an in-depth conceptual analysis to hold power structures responsible as direct and indirect drivers of environmental problems, with their different proportions and severity levels, affecting the planet.

Originality/value
This study proposes an alternative lens to debate and question how much the results presented by the contemporary world order compensate (if in any way) the damage that invades and deteriorate environmental assets.
Privacy or trust: understanding the privacy paradox in users intentions towards e-pharmacy adoption through the lens of privacy-calculus model
Authors: Ashrafi Dewan Mehrab , Ahmed Selim , Shahid Tazrian Shainam 
Published: May 2024

Purpose
This study aims to present a comprehensive investigation into users’ behavioural intentions to use e-pharmacies through the lens of the privacy calculus model. The present study also investigates the effects of perceived benefit, perceived privacy risk, timeliness and perceived app quality on e-pharmacy usage through the mediating role of trustworthiness.

Design/methodology/approach
The study used a deductive approach and collected data from 338 respondents using the purposive sampling technique. partial least squares structural equation modelling was applied to analyse the data.

Findings
The findings of the study indicate that perceived benefit, perceived privacy risk, timeliness and perceived app quality do not directly impact users’ behavioural intentions towards e-pharmacy adoption. Instead, it demonstrated that perceived benefit, perceived privacy risk, timeliness and perceived app quality influenced behavioural intention indirectly through the mediating role of trustworthiness

Originality/value
This study offers valuable insights to entrepreneurs, marketers and policymakers, enabling them to develop regulations, guidelines and policies that cultivate trust, safeguard privacy, ensure prompt services and create an enabling environment for the adoption of e-pharmacies. The present study also contributes to the existing literature by extending the privacy calculus model with the integration of timeliness and perceived app quality to explain users’ adoption behaviour towards e-pharmacy.
Chemical treatment in 3D dental model production for clear aligners via additive manufacturing: a comprehensive evaluation
Authors: Ehteshamfar Mohammad Vahid , Kiadarbandsari Amir , Ataee Ali , Ghozati Katayoun , Bagherkhani Mohammad Ali 
Published: May 2024

Purpose
Stereolithography (SLA) additive manufacturing (AM) technique has enabled the production of inconspicuous and aesthetically pleasing orthodontics that are also hygienic. However, the staircase effect poses a challenge to the application of invisible orthodontics in the dental industry. The purpose of this study is to implement chemical postprocessing technique by using isopropyl alcohol as a solvent to overcome this challenge.

Design/methodology/approach
Fifteen experiments were conducted using a D-optimal design to investigate the effect of different concentrations and postprocessing times on the surface roughness, material removal rate (MRR), hardness and cost of SLA dental parts required for creating a clear customized aligner, and a container was constructed for chemical treatment of these parts made from photocurable resin.

Findings
The study revealed that the chemical postprocessing technique can significantly improve the surface roughness of dental SLA parts, but improper selection of concentration and time can lead to poor surface roughness. The optimal surface roughness was achieved with a concentration of 90 and a time of 37.5. Moreover, the dental part with the lowest concentration and time (60% and 15 min, respectively) had the lowest MRR and the highest hardness. The part with the highest concentration and time required the greatest budget allocation. Finally, the results of the multiobjective optimization analysis aligned with the experimental data.

Originality/value
This paper sheds light on a previously underestimated aspect, which is the pivotal role of chemical postprocessing in mitigating the adverse impact of stair case effect. This nuanced perspective contributes to the broader discourse on AM methodologies, establishing a novel pathway for advancing the capabilities of SLA in dental application.

Published: May 2024

Purpose
The lightweight design of aircraft seats can significantly improve fuel efficiency and reduce greenhouse gas emissions. Metal additive manufacturing (MAM) can produce lightweight topology-optimized designs with improved performance, but limited build volume restricts the printing of large components. The purpose of this paper is to design a lightweight aircraft seat leg structure using topology optimization (TO) and MAM with build volume restrictions, while satisfying structural airworthiness certification requirements.

Design/methodology/approach
TO was used to determine a lightweight conceptual design for the seat leg structure. The conceptual design was decomposed to meet the machine build volume, a detailed CAD assembly was designed and print orientation was selected for each component. Static and dynamic verification was performed, the design was updated to meet the structural requirements and a prototype was manufactured.

Findings
The final topology-optimized seat leg structure was decomposed into three parts, yielding a 57% reduction in the number of parts compared to a reference design. In addition, the design achieved an 8.5% mass reduction while satisfying structural requirements for airworthiness certification.

Originality/value
To the best of the authors’ knowledge, this study is the first paper to design an aircraft seat leg structure manufactured with MAM using a rigorous TO approach. The resultant design reduces mass and part count compared to a reference design and is verified with respect to real-world aircraft certification requirements.

Authors: Simpeh Eric Kwame , Akoto Matilda , Mensah Henry , Ahadzie Divine Kwaku , Duah Daniel Yaw Addai , Reney Nonic Akwasi 
Published: May 2024

Purpose
In the Global North, affordable housing has evolved and thrived, and it is now gaining traction in the Global South, where governments have been vocal supporters of the concept. Therefore, this paper aims to investigate the important criteria for selecting affordable housing units in Ghana.

Design/methodology/approach
A quantitative research approach was used, and a survey was administered to the residents. The data was analysed using both descriptive and inferential statistics. The relative importance index technique was used to rank the important criteria, and the EFA technique was used to create a taxonomy system for the criteria.

Findings
The hierarchical ranking of the most significant criteria for selecting affordable housing includes community safety, waste management and access to good-quality education. Furthermore, the important criteria for selecting affordable housing are classified into two groups, namely, “sustainability criteria” and “housing demand and supply and social service provision”.

Research limitations/implications
This study has implications for the real estate industry and construction stakeholders, as this will inform decision-making in terms of the design of affordable housing and the suitability of the location for the development.

Originality/value
These findings provide a baseline to support potential homeowners and tenants in their quest to select affordable housing. Furthermore, these findings will aid future longitudinal research into the indicators or criteria for selecting suitable locations for the development of low- and middle-income housing.
Phenological mismatch between trees and wildflowers: Reconciling divergent findings in two recent analyses

Published: May 2024

Abstract

Recent evidence suggests that community science and herbarium datasets yield similar estimates of species' phenological sensitivities to temperature. Despite this, two recent studies by Alecrim et al. (2023) and Miller et al. (2022) found very different results when using different data sources (community science and herbarium specimens, respectively) to investigate whether warming threatens wildflowers with phenological mismatch in relation to shading by deciduous trees.

Here, we investigated whether differences between the two studies' results could be reconciled by testing four hypotheses related to model design, species, spatiotemporal data extent and phenophase.

Hybrid model structures brought results from the two datasets closer together but did not fully reconcile the differences between the studies. Neither the species nor the phenophase selected for analysis seemed to be responsible for differences in results. Cropping the datasets to match spatial and temporal extents appeared to reconcile most differences but only at the cost of much higher uncertainty associated with reduced sample size.

Synthesis: Our analysis suggests that although species‐level estimates of phenological sensitivity may be similar between community science and herbarium datasets, inherent differences in the types and extent of data may lead to contradictory inference about complex biotic interactions. We conclude that, until community science data repositories expand to match the range of climate conditions present in herbarium collections or until herbarium collections match the spatial extent and temporal frequency of community science repositories, ecological studies should ideally be evaluated using both datasets to test the possibility of biased results from either.
Establishing a Recovery Menu to Increase the Resilience of Entrepreneurs
Authors: Battisti Martina , Gish J. Jeffrey , Hatak Isabella , Zhou Haibo 
Published: May 2024

AbstractBuilding on the Effort Recovery Model and Conservation of Resources Theory, this study provides new theoretical and empirical insights into how entrepreneurs increase their resilience by engaging in recovery experiences. Employing a longitudinal repeated survey design applied to 346 entrepreneurs, our findings reveal that control is the only recovery experience that directly influences resilience. We also uncover more complex indirect pathways through positive reappraisal and sleep. Overall, the study demonstrates that each recovery experience has a unique relationship with resilience, allowing us to theorize potential underlying mechanisms for how recovery translates into resilience. We offer practical suggestions for effective interventions addressing the recovery paradox in entrepreneurship during times of change and uncertainty.
Customary ‘child selling’ and the ‘untouched mother’ in Western Odisha, India: understanding the legitimatization of caste hierarchy
Authors: Bag Minaketan , Podh Kishor K. 
Published: May 2024

AbstractThe place of mothers is respected in all societies irrespective of their social, cultural, and geographical differences. The mother‐child relationship is considered one of the most sacred in the world. This article explores the age‐old customary ‘child selling’ prevalent in Western Odisha, a voluntary and non‐remunerative practice of childcare during infancy to save children from illness and Yama, the Hindu god of death, where the ‘caring mother’ belongs to the bottom of the social hierarchy, mainly from the (ex‐)untouchable castes. According to popular belief, Yama does not visit the untouchables because of their ‘filthy’ environment and their gods. Hence, it is considered a safer place for children, especially weak ones or those with the chronic illnesses of the upper castes, to conceal themselves from the evil eyes of Yama. The epistemology of this article aims to explore the hegemonic nature of the caste systems, which overwhelms the revered mother‐child relationship. Further, it tries to understand the (re)production of caste and legitimization of sociopsychological conditions for the marginalization and backwardness of ‘caring mothers’. Despite the sacred and intimate relationship between the ‘caring mother’ and child, the institution of ‘ritual selling’ reproduces caste inequalities, and again the former becomes an ‘untouchable’.

Published: May 2024

BackgroundUpper elementary grade students encounter increasingly complex texts with abundant morphologically complex words. Despite the positive effects of morphology‐based vocabulary instruction, emergent bilinguals with limited word reading skills may need additional support.MethodsThis study investigated the effects of morphological analysis and morphophonemic analysis instruction on the orthographic and semantic learning of morphologically complex academic words. Fourth‐ and fifth‐grade Spanish–English bilingual students (N = 30) in the United States participated in two learning tasks. In learning task one, participants learned two sets of carefully matched derivational words under morphological and whole‐word learning conditions. In learning task two, the same participants learned two other sets of words under morphophonemic and whole‐word learning conditions. Each learning task included two learning sessions interweaved by meaning recall and spelling production assessments. Cross‐classified multilevel regression was used to assess the effects of intervention conditions, child and item predictors, as well as cross‐level interactions.ResultsFindings showed no significant difference in meaning recall and spelling measures between morphological and whole‐word conditions. Students performed significantly better in the morphophonemic condition than in the whole‐word condition for both meaning and affix spelling outcomes. The effect of morphophonemic intervention over whole word condition was stronger for younger students and words of lower base frequencies. Student meaning and spelling performance was significantly predicted by their word reading skills.ConclusionsMorphophonemic analysis instruction enhances word meaning recall and spelling of complex derivative words.
Relative Performance Evaluation and Strategic Peer‐Harming Disclosures
Authors: BLOOMFIELD MATTHEW J. , HEINLE MIRKO S. , TIMMERMANS OSCAR 
Published: May 2024

ABSTRACTMany firms use relative stock performance to evaluate and incentivize their CEOs. We document that such firms routinely disclose information that harms their peers' stock prices, and sometimes explicitly mention the harmed peers, by name, in these disclosures. Consistent with deliberate sabotage, peer‐harming disclosures appear to be aimed at peers whose stock price depressions are most likely to benefit the disclosing firms' CEOs. The pricing effect of these disclosures does not reverse, suggesting that the disclosures contain legitimate information regarding peers' prospects. In sum, our results suggest that relative performance evaluation in CEO pay motivates CEOs to internalize the externalities of their disclosures, and strategically disclose information that harms peers' stock prices, in order to improve their firms' relative standing within their peer group.
