Cas4/1 dual nuclease activities enable prespacer maturation and directional integration in a type I-G CRISPR-Cas system
Authors: Dhingra Yukti , Sashital Dipali G.
Published: June 2023

CRISPR-Cas adaptive immune systems uptake short ‘spacer’ sequences from foreign DNA and incorporate them into the host genome to serve as templates for crRNAs that guide interference against future infections. Adaptation in CRISPR systems is mediated by Cas1-Cas2 complexes that catalyze integration of prespacer substrates into the CRISPR array. Many DNA targeting systems also require Cas4 endonucleases for functional spacer acquisition. Cas4 selects prespacers containing a protospacer adjacent motif (PAM) and removes the PAM prior to integration, both of which are required to ensure host immunization. Cas1 has also been shown to function as a nuclease in some systems, but a role for this nuclease activity in adaptation has not been demonstrated. We identified a type I-G Cas4/1 fusion with a nucleolytically active Cas1 domain that can directly participate in prespacer processing. The Cas1 domain is both an integrase and a sequence-independent nuclease that cleaves the non-PAM end of a prespacer, generating optimal overhang lengths that enable integration at the leader side. The Cas4 domain sequence-specifically cleaves the PAM end of the prespacer, ensuring integration of the PAM end at the spacer side. The two domains have varying metal ion requirements. While Cas4 activity is Mn2+dependent, Cas1 preferentially uses Mg2+over Mn2+. The dual nuclease activity of Cas4/1 eliminates the need for additional factors in prespacer processing, making the adaptation module self-reliant for prespacer maturation and directional integration.
Bacterial mimicry of eukaryotic HECT ubiquitin ligation
Authors: Franklin Tyler G. , Brzovic Peter S. , Pruneda Jonathan N.
Published: June 2023

HECT E3 ubiquitin (Ub) ligases direct their modified substrates toward a range of cellular fates dictated by the specific form of monomeric or polymeric Ub (polyUb) signal that is attached. How polyUb specificity is achieved has been a longstanding mystery, despite extensive study ranging from yeast to human. Two outlying examples of bacterial “HECT-like” (bHECT) E3 ligases have been reported in the human pathogens EnterohemorrhagicEscherichia coliandSalmonellaTyphimurium, but what parallels can be drawn to eukaryotic HECT (eHECT) mechanism and specificity had not been explored. Here, we expanded the bHECT family and identified catalytically active,bona fideexamples in both human and plant pathogens. By determining structures for three bHECT complexes in their primed, Ub-loaded states, we resolved key details of the full bHECT Ub ligation mechanism. One structure provided the first glimpse of a HECT E3 ligase in the act of ligating polyUb, yielding a means to rewire the polyUb specificity of both bHECT and eHECT ligases. Through studying this evolutionarily distinct bHECT family, we have not only gained insight into the function of key bacterial virulence factors but also revealed fundamental principles underlying HECT-type Ub ligation.
Monocyte Adhesion and Transmigration Through Endothelium Following Cardiopulmonary Bypass Shearing is Mediated by IL-8 Signaling
Authors: Zhou Hao , Tu Lan N , Giachelli Cecilia , Nigam Vishal , Scatena Marta
Published: June 2023

Background

The use of cardiopulmonary bypass (CPB) can induce sterile systemic inflammation that contributes to morbidity and mortality, especially in children. Patients have been found to have increased expression of cytokines and transmigration of leukocytes during and after CPB. Previous work has demonstrated that the supraphysiologic shear stresses present during CPB are sufficient to induce proinflammatory behavior in non-adherent monocytes. The interactions between shear stimulated monocytes and vascular endothelial cells have not been well studied and have important translational implications.

Methods

To test the hypothesis that non-physiological shear stress experienced by monocytes during CPB affects the integrity and function of the endothelial monolayer via IL-8 signaling pathway, we have used an in vitro CPB model to study the interaction between THP-1 monocyte-like cells and human neonatal dermal microvascular endothelial cells (HNDMVECs). THP-1 cells were sheared in polyvinyl chloride (PVC) tubing at 2.1 Pa, twice of physiological shear stress, for 2 hours. Interactions between THP-1 cells and HNDMVECs were characterized after coculture.

Results

We found that sheared THP-1 cells adhered to and transmigrated through the HNDMVEC monolayer more readily than static controls. When co-culturing, sheared THP-1 cells also disrupted in the VE-cadherin and led to reorganization of cytoskeletal F-actin of HNDMVECs. Treating HNDMVECs with IL-8 resulted in upregulation of vascular cell adhesion molecule 1 (VCAM-1) and intercellular adhesion molecule 1 (ICAM-1) while also increasing the adherence of non-sheared THP-1 cells. Preincubating HNDMVECs with Reparixin, an inhibitor of CXCR2/IL-8 receptor inhibited sheared THP-1 cell adhesion to the HNDMVECs.

Conclusions

These results suggested that IL-8 not only increases the endothelium permeability during monocyte migration, but also affects the initial adhesion of monocytes in a CPB setup. This study revealed a novel mechanism of post-CPB inflammation and will contribute to the development of targeted therapeutics to prevent and repair the damage to neonatal patients.

Highlights

Shear stress in a CPB-like environment promoted the adhesion and transmigration of monocytes to and through endothelial monolayer.

Treating endothelial monolayer with sheared monocytes led to disruption of VE-cadherin and reorganization of F-actin.

Interaction between sheared monocytes resulted in a significant increase of IL-8 release.

Inhibiting IL-8 receptor prevented sheared monocyte adhesion, while IL-8 promoted naive monocyte adhesion.
How streamer channels influence luxury brand sales in live streaming commerce: an empirical study
Authors: Li Guoxin , Tang Peiwen , Feng Jiao
Published: June 2023

Purpose

This study aims to understand how different levels of streamer channels influence luxury brand sales in live streaming commerce. This study also seeks to understand the conditions under which luxury brands may benefit more from different level streamer channels.

Design/methodology/approach

Panel data were collected from 17 international luxury brands on the Douyin live streaming platform in an 18 week period from August to December 2020 and analyzed by using a two-way fixed effects model.

Findings

The authors compared different mega-, macro- and micro-streamer channels within live streaming commerce and found that the densities of mega- and macro-streamer channels had significant positive impacts on luxury brand sales in live streaming commerce. Moreover, the effects of the density of streamer channel on luxury brand sales were moderated by such variables as product line breadth, product line depth, product type (star/non-star) and product price (high/low). The authors found that product line breadth and depth could reduce the positive impact of the densities of mega- and macro-streamer channels on luxury brand sales. For star products and high-priced products, the relationship between the density of mega-streamer channel and luxury brand sales was more likely to be observed than for non-star products and low-priced products. The relationship between the density of macro-streamer channel and luxury brand sales was more likely to be observed in low-priced products than in high-priced products.

Originality/value

The findings make important contributions to the literature in that the authors expand the influencer-brand fit theory by proposing a new model of effects of the densities of mega-, macro- and micro-streamer channels on sales performance across different luxury products to improve our understanding of the fit among influencers, brands and products. This helps luxury brands make basic decisions of “who sells” and “sells what” when engaging in live streaming commerce.

Authors: Owusu-Sekyere Enoch , Hansson Helena , Telezhenko Evgenij , Nyman Ann-Kristin , Ahmed Haseeb
Published: June 2023

Purpose

The purpose of this paper was to assess the economic impact of investment in different animal welfare–enhancing flooring solutions in Swedish dairy farming.

Design/methodology/approach

The authors developed a bio-economic model and used stochastic partial budgeting approach to simulate the economic consequences of enhancing solid and slatted concrete floors with soft rubber covering.

Findings

The findings highlight that keeping herds on solid and slatted concrete floor surfaces with soft rubber coverings is a profitable solution, compared with keeping herds on solid and slatted concrete floors without a soft covering. The profit per cow when kept on a solid concrete floor with soft rubber covering increased by 13%–16% depending on the breed.

Practical implications

Promoting farm investments such as improvement in flooring solution, which have both economic and animal welfare incentives, is a potential way of promoting sustainable dairy production. Farmers may make investments in improved floors, resulting in enhanced animal welfare and economic outcomes necessary for sustaining dairy production.

Originality/value

This literature review indicated that the economic impact of investment in specific types of floor improvement solutions, investment costs and financial outcomes have received little attention. This study provides insights needed for a more informed decision-making process when selecting optimal flooring solutions for new and renovated barns that improve both animal welfare and ease the burden on farmers and public financial support.

Real men don’t share (online): perceived neediness and the frequent-posting femininity stereotype
Authors: Edelblum Andrew B. , Warren Nathan B.
Published: June 2023

Purpose

Research emphasizes the motivations underlying and potential harmful consequences of social media use, but there is little understanding of stigmas faced by individual social media users, particularly as they pertain to gender. The purpose of this study is to examine a unique stereotype related to men’s social media use.

Design/methodology/approach

Four experiments examine judgments of men based on how often they post on social media (frequently vs infrequently).

Findings

The authors find that posting frequently (vs infrequently) affects the perceived gender of men but not women. This frequent-posting femininity stereotype is explained by perceived neediness and holds regardless of whether posts are about others (vs the self) or whether posts are shared by influencers (vs ordinary users).

Research limitations/implications

Future research should examine other stereotypes of social media users – including those pertaining to gender – and ways to mitigate such negative attributions. Researchers should examine how the frequent-posting femininity stereotype and other social media use stereotypes affect social media consumption and consumer well-being.

Practical implications

Managers should adjust consumer engagement strategies and restructure platforms to address the unique stigmas facing different consumer groups.

Originality/value

Providing insights into the dark side of social media, the authors investigate a unique domain – stereotypes about individual social media users. The findings of this study uncover an emasculating stigma against men who post often on social media, which may discourage men from online participation.

Second, it offers a 2 × 2 taxonomy of virtual influencers, grounded in research on anthropomorphism and reality–virtuality. Third, this paper reflects on the opportunities and dangers associated with virtual influencer marketing, outlining avenues for future research.
Baffle effects on enhancing cooling performance of electronic components by nanofluid in a horizontal channel
Authors: Armou Sara , Ait Hssain Mustapha , Nouari Soufiane , Mir Rachid , Zine-Dine Kaoutar
Published: June 2023

Purpose

The purpose of this study is to investigate the impact of varying baffle height and spacing distance on heat transfer and cooling performance of electronic components in a baffled horizontal channel, using a Cu-H2O nanofluid under mixed convection and laminar flow.

Design/methodology/approach

The mathematical model is two-dimensional and comprises a system of four governing equations, such as the conservation of continuity, momentum and energy. To obtain numerical solutions for these equations, the finite volume method was used for discretization. A validation process was performed by comparing this study’s results with those of previously published studies. The comparison revealed a close agreement. The numerical study was performed for a wide range of key parameters: The baffle height (0 ≤ h ≤ 0.7), the spacing distance between baffle and blocks (0.25 ≤ w ≤ 3), the Grashof and Reynolds numbers are kept equal to 104 and 75, respectively, the channel aspect ratio is L/H = 10, and the volume fraction of Cu nanoparticles is fixed at φ = 5%.

Findings

The results of the study reveal a significant improvement in heat transfer in terms of total Nusselt number of the top and bottom hot components, which exhibited an improvement of 16.89% and 17.23% when the baffle height increases from h = 0 to h = 0.7. Additionally, the study found that reducing the distance between the baffle and the electronic components up to a certain limit can improve the heat transfer rate. Therefore, the optimal height of the baffle was found to be no lower than 0.6, and the recommended distance between the heaters and the baffle was 0.5.

Originality/value

This study provides valuable insights into the optimization of the design of baffled channels for improved heat transfer performance. The findings of study can be used to improve heat exchangers and cooling systems in various applications. The use of Cu-H2O nanofluid under mixed convection and laminar flow conditions in channel with baffle and electronic components is also unique, making this study an original contribution to the field.

Determinants of branching decisions of State-controlled commercial banks: evidence from China
Authors: Sun Xifang , Liu Liyu
Published: June 2023

Purpose

Branching is one of the crucial strategic non-price actions for banks. Previous studies on the impact of state ownership upon banks focus on bank lending behavior. This paper aims to offer a novel investigation of how state ownership affects bank branching behavior by examining state-controlled commercial banks (SCCBs) in the context of the largest developing and transitional country China.

Design/methodology/approach

The two-part model (TPM) is applied to analyze the branching decision process. In the first stage, the dependent variable is the choice of bank branching dynamics and in the second stage the dependent variable is the number of new branches or the number of closed branches. For robustness check, the ordered probit selection model allowing for interdependence of the two stage decisions is also employed.

Findings

Using a unique dataset of bank branches in China, this paper finds that the branching decisions of Chinese SCCBs are driven by both profit motivated factors including population size, population density, income level, financial development and banking competition and politically motivated factors as represented with the proportion of SOEs. As a comparison, branching decisions of joint-stock banks in China are fully determined by profit motivated factors.

Originality/value

First, this study is the first to explore the effect of state ownership on bank branching decisions, providing a new insight on the literature regarding to the impact of state ownership on bank decisions. Second, this study explores the potential effect of politically motivated factors on bank branching decisions, filling the gap in bank branching literature. Third, this study can contribute to bank branching literature by enriching the limited understanding of how SCCBs make branching decisions. Lastly, this study applies novel empirical strategies to analyze bank branching decisions, including the TPM and the ordered probit selection model.
The perception of competition in the hospital healthcare market of the Republic of Moldova
Authors: Aneste Eduard , Lozan Oleg
Published: June 2023

Purpose

Identifying the perception of competition between public and private providers in the national hospital market can help authorities to develop appropriate management strategies applicable to the hospital sector and increase the efficiency of public hospital institutions.

Design/methodology/approach

A mixed selective descriptive study including quantitative and qualitative components was carried out on in the Republic of Moldova between 12/2021 and 03/2022. The study included all hospitals in the country. The study revealed the hospital manager's perception of the hospital's competition as respondents to the questionnaire were only the directors and managers of hospital institutions. The concept of evaluation of the perception of competition was carried out through the lens of “Porter's 5 forces” from “Competitive strategies” by Michael E. Porter. The authors used a questionnaire as an instrument for studying the perception of competition. All study participants responded to both the quantitative and qualitative questionnaire.

Findings

Interhospital competition perceived by managers using model framework of “Porter's 5 forces” reveals high danger from service providers and high perception of rivalry; hospital directors perceived as low: the patient's bargaining power; the danger of new competitors entering the market; the danger of substitution, which constitutes competitive advantages; the lack of autonomy in the selection of services and patients and legislative barriers are the main perceived dissensions. The perception of competition between public and private hospitals is one with high rivalry, especially in the country's municipalities.

Originality/value

The national public hospital system takes up to 65% of the health budget being extremely expensive, a fact that indicates a rather low competitiveness of them. The European average indicates figures of 30–40%. The private hospital sector is less developed compared to most European countries, being represented by 17 institutions, in comparison Romania has 104 private hospitals representing about 25% of the market share. Private hospitals also occupy a considerable part of the European hospital healthcare market, continuing to increase, reaching over 30% in Germany.

Authors: Das Seema , Jha Sumi
Published: June 2023

Purpose

Despite the significance of a gender-diverse workforce, there is a lack of comprehensive review of gender diversity and women's career advancement literature. Moreover, past literature focuses on women-on-board and other subsets based on outcomes like firm financial and non-financial performance, corporate social performance and board interlocks. The purpose of this study is to examine the research on gender diversity and women's career advancement through an analysis of 143 articles published during past decade. Theoretical frameworks, contexts and constructs-based contribution to scholarship were reviewed. The authors attempt to highlight key theories, constructs and contexts and provide direction for future research.

Design/methodology/approach

A comprehensive systematic literature review of 143 articles spanning January 2008–March 2023 about gender diversity and women’s career advancement was conducted.

Findings

Majority of the past studies have focused on women on board and top management team, and most of them have been conducted in the context of the USA and China. There is no specific industry which has been covered extensively. Resource dependency, resource-based views and agency theories are the primary theoretical frameworks used in the past studies. Furthermore, these findings suggest the scope to further focus on women’s retention and career growth initiatives, especially at levels other than top levels, for a stronger leadership pipeline.

Originality/value

This study has been conducted with a focused analysis of the context, constructs and theoretical frameworks, enabling future researchers to decide how and where to focus, to now strengthen retention of women.
What transforms? – Transformative learning in a sustainability leadership master’s program
Authors: Bryant Jayne , Ayers James , Missimer Merlina
Published: June 2023

Purpose

Transformative learning and leadership are key leverage points for supporting society’s transition towards sustainability. The purpose of this study was to identify the outcomes of transformational learning within an international sustainability leadership master’s program in Sweden. The study also prototypes a typology for transformative learning (TTL) in the context of sustainability leadership education.

Design/methodology/approach

Alumni spanning 15 cohorts provided answers to a survey, and the responses were used to identify the outcomes of the program. Graduates were asked to describe what transformed for them through the program. Empirical data was coded prototyping the use of the TTL in sustainability education context.

Findings

Graduates of the Master’s in Strategic Leadership towards Sustainability program, described transformation with regards to their Self-in-relation to Others and the World, their Self-knowledge, sense of Empowerment/Responsibility; their Worldview became More Comprehensive or Complex, and they gained New Awareness/New Understandings which transformed their Worldview. Many described transformations in their general Ways of Being in the world. Findings suggest the TTL learning as a good basis for analysis in the education for sustainable development (ESD) context. Suggestions for the TTL include further development of the process that articulates the relational, interdependent and perhaps a priori relationships between elements that transform.

Research limitations/implications

This study presents the outcomes of transformational learning within an international sustainability leadership master’s program. It prototypes the use of a TTL within the ESD context using empirical data. This combination provides practical insights to a dynamic, often theoretical and hard to articulate process.

Originality/value

Growing a digital iceberg for a polar bear: effects of a gamified mobile app on university students’ pro-environmental behaviours
Authors: Boncu Ștefan , Candel Octav-Sorin , Prundeanu Oara , Popa Nicoleta Laura
Published: June 2023

Purpose

Pro-environmental education incorporates digital technologies to enhance the level of pro-environmental behaviours (PEB) in young adults. Guided by gamified learning and self-directed informal learning theories, this study aims to examine the potential for the use of a gamified mobile app to increase students’ PEB. Also, it explores whether various pre-existing environmental attitudes and beliefs can moderate the effects.

Design/methodology/approach

This quasi-experimental study proposed an eight-weeks intervention for undergraduate students based on using a mobile app. The authors evaluated the post-intervention differences in PEB between the intervention group and a control group. The effects of multiple moderators were also tested.

Findings

Using the mobile app for eight weeks significantly improves the levels of PEB in the intervention group compared to the control group. None of the proposed interactions showed significant moderator effects.

Originality/value

To the best of the authors’ knowledge, this study is the first one to verify the potential moderators accounting for the success of an environmental education approach using a mobile app. Also, it provides strong empirical support for the use of such educational strategy. Based on these findings, the authors suggest the use of gamified mobile apps as suitable tools for pro-environmental education, especially when targeting young adult or student populations. Moreover, using mobile apps providing self-directed informal learning, combined with gamification, can be used to enhance other desirable behaviours.
Numerical simulation and experimental study on adhesion effect of powder lubricating layer
Authors: Kong Junchao
Published: June 2023

Purpose

Powder lubrication is widely used in industrial production, but most of the research that analyze the wear process and speculate on the wear mechanism of the tested specimens lacks reliability, and it is difficult to reveal the essence of the friction and wear process. The purpose of this paper is using the optical in situ observation method to observe the condition of the powder lubrication layer in real time and dynamically, and directly obtain the morphology change of the specimen during the whole wear process, which is helpful to the establishment of new tribological basic theories such as friction and wear mechanism and lubrication theory.

Design/methodology/approach

Mechanical model of powder lubrication is established considering asperity and powder layer, and the influence of adhesion effect on load and friction force is analyzed. The finite difference method is used to solve the above physical model, and the influence of the adhesion effect on load and friction force is analyzed. The total load and friction of the friction pair are composed of two parts: fluid and asperity. Based on the optical in situ observation method to build a test platform. The interface of the adhesion stage was observed by SEM.

Findings

When the film thickness ratio is less than 1, the local damage and diffusion of the powder layer are basically completed and the adhesion stage is entered. At this time, the asperity is not fully loaded, the powder layer is loaded by 50%, the asperity is less loaded, the deformation is small and the possibility of plastic flow is reduced. However, in the adhesion stage, the friction force is basically generated between asperity, and the friction force ratio of the asperity is 80%. Heavy load and surface roughness of the specimen are the necessary conditions for the powder adhesion period.

Practical implications

In this paper, the failure process of the powder layer at the friction interface with different roughness and load is studied based on the optical in situ observation method. Second, the contact surface with the micro-convex body and powder layer is simulated, and the influence of adhesion effect on the mechanical properties of the real contact surface in the process of powder lubrication is analyzed, thus providing theoretical guidance for mechanical processing, workpiece operation and lubrication design.

Originality/value

Mechanical model considering asperities and powder layer powder lubrication was established to analyze the influence of the adhesion effect on load and friction. Based on the optical in situ observation method to build a test platform. The tests found that the failure process of the powder lubricating layer includes five stages: powder complete stage, local failure stage, local failure diffusion stage, powder adhesion stage and complete failure stage.

Constraints on peace research in war-torn situations: Cabo Delgado, Mozambique
Authors: Chirambwi Kudakwashe
Published: June 2023

Purpose

It is assumed that fieldwork experiential learning on constraints of survey and ethnography research orientations in investigating armed conflict in Africa can contribute to the body of knowledge and help practitioners as well as other researchers working in difficult situations, such as war zones. More importantly, this paper aims to understand significant problems in Southern Africa, further methodological debates and produce new frontiers of knowledge in Southern African research studies. This paper will help other researchers who will be planning to conduct research in ongoing war-torn zones to be flexible with mixed research methodologies and data collection techniques that can ensure not only reliability and validity of the data but also, and more importantly, greater generalizability of this study.

Design/methodology/approach

This research in Cabo was initially guided by survey and ethnographic approaches. After facing constraints in their use in investigating the complexity of new wars, the author developed and shifted to interpretivism methodology as an alternative. It is essential that researchers be sensitive to the tensions between survey and ethnography methodologies and how they can be a mismatch to the research purpose.

Findings

The fieldwork experiences, using standardised survey and ethnography research orientations in Gabo, show that there is no generally appropriate blueprint of how to conduct research in violent conflicts. The valorised survey and ethnographic research strategies were not closely matched to facilitate understanding of the complexity of hybrid armed actors, indiscriminate and targeted violence which combined to militate against data generation. In the face of these problems, the author developed a new methodology, interpretivism, which embedded the descriptive, explanatory and predictive approaches. In tumultuous contexts, the standardised methodologies prioritize data generation more than critical thinking.

Originality/value

It is essential to study the nature of African armed conflicts by combining creativity and flexibility in the selection of research strategies. The constraints on peace research in war-torn situations in Cabo Delgado, Mozambique, have laid out the weaknesses of peacetime research methodologies, including survey research and ethnographic approaches. Now is the time to reassess fieldwork-based research particularly in violent settings.

Information systems quality in management accounting and management control effectiveness
Authors: Papiorek Kevin L. , Hiebl Martin R.W.
Published: June 2023

Purpose

Several conceptual works suggest that more digitalized information systems in management accounting have the potential to make this corporate function more effective. Against this backdrop, this study aims to investigate the impact of information systems quality in management accounting on the effectiveness of management control systems. Additionally, this study examines the moderating effect of process automation.

Design/methodology/approach

A cross-sectional survey of 125 German Mittelstand firms and hierarchical regression analyses were used for data collection and analysis.

Findings

The findings confirm the assumed positive effect of information systems quality in management accounting on management control effectiveness. They also confirm the assumed moderating effect of process automation. The authors find that the relationship between information systems quality in management accounting and management control effectiveness is more pronounced if the firm features a higher degree of process automation.

Originality/value

Several earlier case studies and a few quantitative studies indicated the potentially positive effect of high-quality information systems in management accounting on management control effectiveness. To the best of the authors‘ knowledge, this study is among the first to deliver quantitative proof of this relationship in the context of German Mittelstand firms. Moreover, the authors add to this literature the moderating effect of process automation in the relationship between information systems quality in management accounting and management control effectiveness.
What drives social entrepreneurial intentions after retirement from a full-time career? Evidence from Oman
Authors: Razzak Mohammad Rezaur , Al Riyami Said
Published: June 2023

Purpose

Drawing on the socioemotional selectivity theory and the volunteerism literature, this study aims to examine the influence of empathy, altruism and opportunity recognition, on social entrepreneurial intentions (SEI) of people who have retired from a full-time career. Furthermore, the study examines whether the above-mentioned relationships are mediated by moral obligation.

Design/methodology/approach

A set of hypotheses is tested by applying partial least squares structural equation modelling on a survey sample of 227 retirees in Oman, who had participated in an entrepreneurial leadership training after retirement. Using SmartPLS software, the path model is tested through bootstrapping.

Findings

The findings suggest that altruism and opportunity recognition do not have a direct relationship with SEI, however, they are significant only when mediated through moral obligation. Nevertheless, empathy has a significant direct association with SEI, and an indirect relationship through moral obligation.

Practical implications

The findings of this study demonstrate that to develop intentions to indulge in social entrepreneurship, among retirees who are approaching their senior years, the focus should be on driving their sense of moral obligation to society. Hence, policymakers and authorities connected to social wellbeing goals can fine-tune their initiatives, such as training, by emphasizing on moral obligation to address social issues through social entrepreneurship.

Originality/value

The novelty of this study is twofold. Firstly, to the best of the authors’ knowledge, it seems to be among the first empirical study that is at the crossroads of the senior entrepreneurship and the social entrepreneurship literature. Secondly, this study fills a gap in the extant literature by deploying the socioemotional selectivity theory to examine the antecedents of SEI of people who have retired from full-time employment in their early to late senior years.

Purpose

This paper aims to explore a framework for implementing Lean Construction (LC) to provide corrective actions for quality defects, customer dissatisfaction and value creation during the construction of megaprojects.

Design/methodology/approach

This paper presents a case study involving the construction of the Mohamed VI Tower in Morocco. It is the tallest tower in Africa, with 55 floors and a total height of 250 m. This study of the quality of the work and the involvement of the LC was carried out using the Define–Measure–Analysis–Improve–Control approach from Lean six sigma. It describes the Critical to Quality and analyses the root causes of quality defects, customer dissatisfaction and variation in the quality process.

Findings

Firstly, the results of this study map the causal factors of lack of quality as established in the literature. Secondly, the LC tools have reduced non-value-added sources of quality waste and, consequently, improved critical quality indicators.

Research limitations/implications

This document focuses on one part of the tower’s construction and is limited to a project case in a country where LC is rarely used.

Originality/value

This study reinforces the literature reviews, surveys and the small number of case studies that have validated the potential of LC and further clarifies future directions for the practical emergence of this quality improvement approach, especially for large-scale projects.
The equilibrium domestic abuse behaviour change and healthy relationships programme: a service description and evaluation framework
Authors: Thomas Dafydd , Stevens Megan , Davies Jason
Published: June 2023

Purpose

Domestic abuse (DA) is a major issue with serious psychological, social, societal and economic impacts. Consequently, there has been an increased focus by policymakers and multiple statutory and third-sector agencies on addressing harms associated with DA and fostering healthy intimate and domestic relationships. This paper details the development and implementation of a whole family approach to DA set within a community social services setting.

Design/methodology/approach

A detailed description of the development and implementation of a new whole family approach is provided. This includes a focus on the equilibrium programme, an accredited strengths-based, solution-focused group element that has been devised and established for those engaging in harmful behaviours.

Findings

The importance of governance, programme support and practitioner supervision are discussed along with the ways these are used by the service. The evaluation framework presented will enable the impact of the programme to be determined over the coming years.

Practical implications

There is clear need to address the significant problem of DA/intimate partner violence. This paper provides a model and accredited treatment approach to implementing a whole family approach to DA set within a community social services setting. This provides an opportunity for early intervention based on a strengths-based, solution focussed approach to addressing harmful behaviours and building skills and resilience.

Originality/value

This paper details a whole system approach to early intervention with families in which there is DA. Providing input via social care child and family support services prior to legal involvement provides an opportunity to avoid an escalation of harms. It also enables solutions to conflict to be found which take account of the relationship between parents and children.
Interest rates and Islamic commercial property financing: can there be a possible solution?
Authors: Harun Siti Latipah , Mohd Yusof Rosylin , Abd. Wahab Norazlina , Aliyu Sirajo
Published: June 2023

Purpose

This study aims to investigate the dynamic interaction between interest rates and commercial property financing offered by Islamic banks in Malaysia.

Design/methodology/approach

The authors use the autoregressive distributed lag (ARDL) cointegration methodology to analyse the short- and long-run effect of the interest rates and rental rates on commercial property financing of Islamic banks in Malaysia between 2010: Q1 and 2018: Q2.

Findings

The findings reveal that changes in interest rates affect Islamic commercial property financing. This indicates that Islamic banks still rely on interest rates as a benchmark without fully implementing Islamic rental rates. This corroborates the subsequent finding, where overnight policy rates influence commercial property financing.

Research limitations/implications

Despite the authors’ attempt to provide insights into Islamic commercial property financing, the study is limited to secondary data; further research can use survey information to obtain other details that are not included in this study. Similarly, this study does not cover the operation and financial lease debate in Musharakah Mutanaqisah. Future studies can examine the challenges faced by the financial institution towards implementing rental rates in other emerging and developing countries using a different methodology.

Originality/value

This study is the first to investigate the dynamic changes in overnight policy rates, average lending rates and rental rates on Islamic commercial property financing in Malaysia using ARDL techniques. The authors uncover the research and institutional implications of Islamic commercial property financing rates and provide policy and future research directions coupled with the proposed modified rental rate to be developed.
Estimating the effects of an anti-racist intervention on campus administrators’ beliefs about racial equity and justice: a quasi-experimental study
Authors: Strayhorn Terrell Lamont
Published: June 2023

Purpose

The purpose of this study is to measure the impact of a novel anti-racist educational video-based intervention designed by the author, with advice from leading experts, on campus administrators’ prevailing beliefs, philosophies and practices about racial equity and justice. A single research question guided the project: what effect, if any, does an anti-racist educational intervention have on college administrators’ awareness, beliefs and knowledge about race (i.e. racial ideologies), equity-mindedness and justice, compared to peers in two control groups?

Design/methodology/approach

This paper is based on a study that employs a quasi-experimental approach, using a pre- and post-test design, to assess the impact of a brief video intervention on college administrators’ awareness, beliefs, and knowledge about anti-racism generally and racial ideologies, equity-mindedness and justice orientations specifically.

Findings

Multivariate analyses suggest the efficacy and effectiveness of the novel anti-racist educational video-based intervention in increasing campus administrators’ racial consciousness, empathy, understanding and equity-mindedness, although no effect was found for justice orientations.

Practical implications

As colleges and universities continue to work toward creating inclusive and equitable workspaces and learning environments, this study suggests that targeted interventions can be used to promote important values and beliefs among campus administrators. Specifically, video-based interventions may be useful tools for staff development programs, implicit bias trainings, diversity and inclusion initiatives, graduate education courses, leadership fellowships, upskilling and micro-credentials, to name a few.

Originality/value

This paper fills an identified need to study anti-racism among campus administrators, the efficacy of scalable interventions that can be easily adapted or integrated into existing campus/staff programming and ways to foster anti-racist awareness, knowledge and actions.
