Authors: Manan Aneel , Zhang Pu , Ahmad Shoaib , Ahmad Jawad 
Published: June 2024

Purpose
The purpose of this study is to assess the incorporation of fiber reinforced polymer (FRP) bars in concrete as a reinforcement enhances the corrosion resistance in a concrete structure. However, FRP bars are not practically used due to a lack of standard codes. Various codes, including ACI-440-17 and CSA S806-12, have been established to provide guidelines for the incorporation of FRP bars in concrete as reinforcement. The application of these codes may result in over-reinforcement. Therefore, this research presents the use of a machine learning approach to predict the accurate flexural strength of the FRP beams with the use of 408 experimental results.

Design/methodology/approach
In this research, the input parameters are the width of the beam, effective depth of the beam, concrete compressive strength, FRP bar elastic modulus and FRP bar tensile strength. Three machine learning algorithms, namely, gene expression programming, multi-expression programming and artificial neural networks, are developed. The accuracy of the developed models was judged by R2, root means squared and mean absolute error. Finally, the study conducts prismatic analysis by considering different parameters. including depth and percentage of bottom reinforcement.

Findings
The artificial neural networks model result is the most accurate prediction (99%), with the lowest root mean squared error (2.66) and lowest mean absolute error (1.38). In addition, the result of SHapley Additive exPlanation analysis depicts that the effective depth and percentage of bottom reinforcement are the most influential parameters of FRP bars reinforced concrete beam. Therefore, the findings recommend that special attention should be given to the effective depth and percentage of bottom reinforcement.

Originality/value
Previous studies revealed that the flexural strength of concrete beams reinforced with FRP bars is significantly influenced by factors such as beam width, effective depth, concrete compressive strength, FRP bars’ elastic modulus and FRP bar tensile strength. Therefore, a substantial database comprising 408 experimental results considered for these parameters was compiled, and a simple and reliable model was proposed. The model developed in this research was compared with traditional codes, and it can be noted that the model developed in this study is much more accurate than the traditional codes.

Published: June 2024

Purpose
Regarding the broadening of the titanium alloy application field, the surface treatment coating of TC4 alloy has become an essential global research topic. This study aims to illustrate the titanium-based composite coating is created by laser cladding TC4+Ni60/hBN composite powder onto the surface of the TC4 alloy.

Design/methodology/approach
Different laser scanning speeds were initially selected to prepare TC4+Ni60/hBN titanium-based composite coating on the surface of TC4 alloy using RFL-C1000 Raycus fiber laser. Second, the cladding layers with different laser scanning speeds are composed of Ti2Ni, TiN0.3, TiC, TiB, α-Ti and other phases. Finally, precision balances, friction and wear testing machines were used to analyze and test the structure, phase, hardness, wear amount and friction coefficient of the composite coating and to study the effect of laser scanning speed on the microstructure and properties of the titanium-based composite coating.

Findings
It is evident that at the low laser scanning speed, the reinforcing phase agglomeration area is distributed in the substrate as a network. Increasing the laser scanning speed can reduce the cladding layer's friction coefficient and improve the cladding layer's hardness and wear resistance. But too high a laser scanning speed will cause defects such as pores and cracks in the cladding layer and also affect the cladding layer. The bonding performance of the layer and the substrate is optimal in this research at a laser scanning speed of 10 mm/s.

Originality/value
This research has practical value in improving the quality of surface treatment coating in modern aerospace and automotive companies.
Approach for sizing by optimization of an electrical drive considering a multiphysics and multidynamics behaviour
Authors: Thomas Robin , Gerbaud Laurent , Chazal Herve , Garbuio Lauric 
Published: June 2024

Purpose
This paper aims to describe a modelling and solving methodology of a (static converter–electric motor–control) system for its sizing by optimization, considering the dynamic thermal heating of the machine.

Design/methodology/approach
The electrical drive sizing model is composed of two simulators (electrical and thermal) that are co-simulated with a master−slave relationship for the time step management. The computation is stopped according to simulation criteria.

Findings
This paper details a methodology to represent and size an electrical drive using a multiphysics and multidynamics approach. The thermal simulator is the master and calls the electrical system simulator at a fixed exchange time step. The two simulators use a dedicated dynamic time solver with adaptive time step and event management. The simulation automatically stops on pre-established criteria, avoiding useless simulations.

Research limitations/implications
This paper aims to present a generic methodology for the sizing by optimization of electrical drives with a multiphysics approach, so the precision and computation time highly depend on the modelling method of each components. A genetic multiobjective optimization algorithm is used.

Practical implications
The methodology can be applied to size electrical drives operating in a thermally limited zone. The power electronics converter and electrical machine can be easily adapted by modifying their sub-model, without impacting the global model and simulation principle.

Originality/value
The approach enables to compute a maximum operating duration before reaching thermal limits and to use it as an optimization constraint. These system considerations allow to over constrain the electrical machine, enabling to size a smaller machine while guaranteeing the same output performances.

Published: June 2024

Purpose
The purpose of this study is to examine the role of dynamic capabilities for improvement of competitiveness of the organizations through enhancement of internationalization performance. The study would also try to assess if there is any moderating impact of leadership abilities of the entrepreneurs to impact internationalization performance of the organizations.

Design/methodology/approach
This study has reviewed various kinds of literature related to competitiveness, international marketing, dynamic capabilities, entrepreneurship and leadership support. This study also used a dynamic capability view to develop a research model. This model was validated using the partial least squares structural equation modeling technique to analyze data from 303 respondents from European and Asian organizations.

Findings
The study found that dynamic capabilities have considerable influence on the competitive international performance of organizations, and entrepreneurs’ leadership ability has a significantly moderator impact on the relationship between dynamic capabilities and international performance of organizations.

Research limitations/implications
The study uncovers the impacts of dynamic abilities on the competitiveness and internationalization performance of the organizations. This study also provided valuable insights about the importance of entrepreneurial leadership ability for improving the internationalization performance of the organizations. This study also highlighted the significance of investing on improving dynamic abilities of the organizations to improve their internationalization performance as well as their competitiveness.

Originality/value
This study has contributed to the prevailing literature on entrepreneurship, leadership capability, competitiveness and dynamic capabilities. Few studies have focused on how dynamic capabilities affect the competitiveness and international performance of organizations. Also, studies are scant to understand if the entrepreneur’s leadership ability has any moderating impact on the relationship between an organization’s dynamic capabilities and its international performance. Therefore, this study aims to investigate these gaps.
New frontiers of fun: sharing and supporting workplace fun in hybrid work
Authors: Plester Barbara , Lloyd Rhiannon 
Published: June 2024

PurposeHybrid work is changing modern conceptions of work as workers move between their office space and alternate spaces such as a home office. Social aspects of work are therefore also changing, and this study aims to explore the implications arising for workplace fun when workspaces become dispersed.Design/methodology/approachWe undertook ethnographic research into two different companies to explore in depth the concept of fun at work and how it is being adapted for hybrid work. Data were collected through full immersion into both companies and gathered using mixed qualitative methods comprising semi-structured interviews, participant observations and evidence from organizational online platforms. A structured coding system was used in the analysis with an interpretive approach.FindingsOur themes include (1) artefacts, (2) organizing fun and space and (3) loss of fun and these provide the underpinning for our theoretical contribution.Research limitations/implicationsWe had limited access to online channels and identified opportunities for future research to explore fun in online platforms including chat functions, meme, gifs and other places where workplace fun may be enacted.Practical implicationsWork has changed for workers and managers, and this impacts fun which needs to adapt to hybrid work models.Social implicationsHybrid work is changing workplace social interactions, particularly, for fun and play. We depict how workers navigate the changing context of work and the significance of emerging elements of workplace fun and the implications for fun cultures.Originality/valueOur contribution is in a re-theorization of workplace fun arguing that sharing and supporting the creation and promotion of fun among workers at all levels offers new opportunities for organizations that value a fun culture. Our theorization of workplace fun shows its adaptation to new hybrid work contexts that deemphasize co-location and physical presence. We outline the significance of artefacts and depict the variability of workplace fun in hybrid work.

Published: June 2024

PurposeThe evolving dynamics of the labour market make graduates’ future employability an important issue for higher education (HE) institutions, prompting universities to complement the conventional graduate skills approach with a wider focus on graduate forms of capital that may enhance their sense of employability. This study, adopting a capital perspective, explores whether and how teachers in HE, when acknowledged as knowledgeable trustworthy actors, may affect graduates’ employability. It investigates how they can mobilise undergraduate cultural capital through socialisation, and shape their pre-professional identity, paving the way for university-to-work transition.Design/methodology/approachTo test the hypothesised model, a self-report online questionnaire was administered to a sample of 616 undergraduates attending different Italian universities. Multiple mediating models were tested using the SEM framework.FindingsResults supported the tested model and showed that trust in knowledgeable HE teachers was associated with undergraduates’ perceived employability both directly and through both mediators (i.e. academic socialisation and identification with future professionality).Research limitations/implicationsThis research explores a capital conceptualisation of graduate employability, identifying possible processes for implementing graduates’ capital across their academic experience and providing initial evidence of their interplay and contribution to transition into the labour market.Originality/valueThese findings provide empirical support to possible forms of capital that HE institutions may fulfil to enhance their undergraduate employability throughout their academic career, which serves as a liminal space allowing undergraduates to begin building a tentative professional identity.
Unpacking the role of transformational leadership and work engagement in the relationship between psychological capital and innovative work behavior
Authors: Alwali Abduljaleel 
Published: June 2024

Purpose
This study aims to determine the effect of psychological capital (PsyCap) on innovative work behavior (IWB) by incorporating the mediating role of work engagement and examine the moderating role of transformational leadership in the relationship between PsyCap and IWB.

Design/methodology/approach
Using a correlational design, this research involved 270 nurses from seven public hospitals across Iraq, selected through purposive sampling. Data analysis was conducted using partial least squares structural equation modeling (SmartPLS 3).

Findings
The distinctness of the variables used in this study was confirmed by confirmatory factor analysis. The findings show that a PsyCap had a positive influence on IWB directly and indirectly through the mediating of work engagement, and transformational leadership positively moderates the relationship between a PsyCap and IWB in such a way that with high transformational leadership behavior, the relationship will be strengthened.

Originality/value
By focusing on Iraqi nurses, this study not only contributes to the existing literature on PsyCap and IWB but also underscores the unique contextual challenges faced by health-care professionals in conflict-affected areas. The findings emphasize the importance of nurturing leadership qualities to foster a resilient and innovative nursing workforce in such settings.
Utilizing computational methods for analysing media framing of organizational crises: The ‘Datalek’ scandal during the COVID‐19 pandemic in the Netherlands

Published: June 2024

AbstractMedia framing of organizational crises is an important factor to consider in crisis communication since it can shape stakeholders' perceptions of organizations and discussions in the public sphere. This takes place in complex media ecologies where public communication happens at a large scale, both in the news and on social media. Here, computational methods offer new venues for analysing media framing in flux throughout the crisis life cycle. Especially methods for automated content analysis can quickly and efficiently reveal what media frames emerge in a crisis context and how they change over time across different channels and platforms. The present study showcases the benefits of such methodological approaches by critically exploring the example of the data breach at the national municipal health service in the Netherlands. Using computational methods for media frame analysis on news texts (N1 = 519) and social media postings (N2 = 2986), this article reconstructs how the incident was perceived throughout four crisis stages (build‐up, outbreak, chronic stage, termination). The article critically discusses the relevance of researching media framing empirically with emphasis on the benefits but also limitations of computational approaches. It concludes with some general pointers for crisis researchers interested in such methods as well as their implications for practitioners in the field.
Income inequality in the United States, 1975–2022
Authors: Hardy Bradley L. , Krause Elizabeth , Ziliak James P. 
Published: June 2024

AbstractWe examine trends in household disposable income inequality and potential mechanisms shaping inequality through changes to work, wages, earnings, marriage, and the tax and transfer system in the United States over the nearly five‐decade period from 1975 to 2022. Overall after‐tax and transfer income inequality increased more than 25 per cent since the mid‐1970s, and by as much as 50 per cent when comparing the 90th and 10th percentiles. While there has been substantial upgrading in formal education credentials among both men and women – an inequality‐reducing development – those with fewer credentials have increasingly been less likely to work and marry, each of which could result in higher inequality. The latter effects are exacerbated by those selecting into marriage and cohabitation being more likely to partner with those holding similar educational credentials and earning power. Moreover, the decline in work among the less skilled coincided with the transformation of the safety net to rewarding work. These demographic and policy changes have resulted in a pulling apart of the US income distribution.

Published: June 2024

AbstractAimTo report the cost of hospitalization and the associated risk factors for rheumatic diseases in middle‐aged and elderly patients in China.MethodsThe study participants included inpatients from hospitals of various levels in the Jiangsu Province Health Account database in 2016. Participants were selected by using a multistage sampling method. Patients <45 years of age were excluded, and patients hospitalized for rheumatic diseases were identified according to the 10th edition of the International Classification of Diseases. Generalized linear models were used to analyze the sociodemographic characteristics related to the hospitalization costs of patients with rheumatic diseases.ResultsThe study included 3696 patients. The average cost of hospitalization for patients with rheumatic diseases was USD 4038.63. Female sex, a long length of stay, age between 65 and 74 years, free medical care, not being covered by the Urban–Rural Residents Basic Medical Insurance, and a high hospital level were associated with high hospitalization costs.ConclusionThis study examined hospitalization costs and relevant influencing factors in middle‐aged and elderly patients with rheumatic disease in China. Our findings are useful for further research on costs of disease and the economic evaluation of strategies to prevent rheumatic disease.

Published: June 2024

AbstractBackgroundOver the past decade, ultrasound utilization has increased within anesthesia and intensive care medicine, enhancing patient safety and diagnostic accuracy. However, the frequency of ultrasound usage and operator training in the Nordic countries remain unclear. This project aims to perform a survey on ultrasound availability, daily clinical use, and how ultrasound skills are trained and assessed, among anesthesiologists.MethodsThis online cross‐sectional survey will include anesthesiologists from the Nordic countries. The survey will adhere to the CROSS checklist. Survey items will be developed based on a formative model with a conceptual model, consisting of three main parts, including demographics, ultrasound machines and use, and skills development and assessment. The clinical relevance of items will be secured by including anesthesiologists of various levels of experience in the development of the survey. Furthermore, experienced researchers in medical education will participate in the development, contributing with relevant medical educational perspectives. Data will be summarized using a non‐parametric descriptive approach. A chi‐squared test will examine relevant relationships between certain answers.ResultsResults will be published in a peer‐reviewed journal and presented at relevant scientific conferences and meetings.ConclusionThis study may find a high availability of ultrasound machines and frequent use in the clinical departments. Despite this expected daily use of ultrasound, missing standardized structured skills acquisition and assessment could be uncovered. The results of this study may contribute to mapping various aspects of clinical ultrasound and skills development for further use in research.
A Tailored Virtual Program for Alcohol Use Disorder Treatment Among Liver Transplant Candidates and Recipients Is Feasible and Associated With Lower Post‐Transplant Relapse

Published: June 2024

ABSTRACTBackgroundAlcohol‐associated liver disease (ALD) is a leading indication for liver transplant (LT) in the United States. Rates of early liver transplant (ELT) with less than 6 months of sobriety have increased substantially. Patients who receive ELT commonly have alcohol‐associated hepatitis (AH) and are often too ill to complete an intensive outpatient program (IOP) for alcohol use disorder (AUD) prior to LT. ELT recipients feel alienated from traditional IOPs.MethodsWe implemented Total Recovery‐LT, a tailored virtual outpatient IOP specific for patients under evaluation or waitlisted for LT who were too ill to attend community‐based alcohol treatment programs. The 12‐week program consisted of weekly group and individual counseling delivered by a master's level Certified Addiction Counselor trained in the basics of LT. Treatment consisted of 12‐Step Facilitation, Motivational Interviewing, and Cognitive Behavioral Therapy. We report on program design, implementation, feasibility and early outcomes.ResultsFrom March 2021 to September 2022, 42 patients (36% female, 23 in LT evaluation, 19 post‐transplant) enrolled across five cohorts with 76% (32/42) completing the program. Alcohol relapse was more common among noncompleters versus those who completed the program (8/10, 80% vs. 7/32, 22%, p = 0.002). History of trauma or post‐traumatic stress symptoms were associated with lower likelihood of completion. Patients’ desire for continued engagement after completion led to the creation of a monthly alumni group.ConclusionsOur integrated IOP model for patients with high‐risk AUD in LT evaluation or post‐transplant is well‐received by patients and could be considered a model for LT programs.
