A numerical solution to thermo‐mechanical behavior of temperature dependent rotating functionally graded annulus disks
Authors: Madan Royal , Bhowmick Shubhankar
Published: June 2021

Purpose

The purpose of this study is to investigate Thermo-mechanical limit elastic speed analysis of functionally graded (FG) rotating disks with the temperature-dependent material properties. Three different material models i.e. power law, sigmoid law and exponential law, along with varying disk profiles, namely, uniform thickness, tapered and exponential disk was considered.

Design/methodology/approach

The methodology adopted was variational principle wherein the solution was obtained by Galerkin’s error minimization principle. The Young’s modulus, coefficient of thermal expansion and yield stress variation were considered temperature-dependent.

Findings

The study shows a substantial increase in limit speed as disk profiles change from uniform thickness to exponentially varying thickness. At any radius in a disk, the difference in von Mises stress and yield strength shows the remaining stress-bearing capacity of material at that location.

Practical implications

Rotating disks are irreplaceable components in machinery and are used widely from power transmission assemblies (for example, gas turbine disks in an aircraft) to energy storage devices. During operations, these structures are mainly subjected to a combination of mechanical and thermal loadings.

Originality/value

The findings of the present study illustrate the best material models and their grading index, desired for the fabrication of uniform, as well as varying FG disks. Finite element analysis has been performed to validate the present study and good agreement between both the methods is seen.
Optimized resource-constrained method for project schedule compression
Authors: Elkabalawy Moaaz , Moselhi Osama
Published: June 2021

Purpose

This paper aims to present an integrated method for optimized project duration and costs, considering the size and cost of crews assigned to project activities' execution modes.

Design/methodology/approach

The proposed method utilizes fuzzy set theory (FSs) for modeling uncertainties associated with activities' duration and cost and genetic algorithm (GA) for optimizing project schedule. The method has four main modules that support two optimization methods: modeling uncertainty and defuzzification module; scheduling module; cost calculations module; and decision-support module. The first optimization method uses the elitist non-dominated sorting genetic algorithm (NSGA-II), while the second uses a dynamic weighted optimization genetic algorithm. The developed scheduling and optimization methods are coded in python as a stand-alone automated computerized tool to facilitate the developed method's application.

Findings

The developed method is applied to a numerical example to demonstrate its use and illustrate its capabilities. The method was validated using a multi-layered comparative analysis that involves performance evaluation, statistical comparisons and stability evaluation. Results indicated that NSGA-II outperformed the weighted optimization method, resulting in a better global optimum solution, which avoided local minima entrapment. Moreover, the developed method was constructed under a deterministic scenario to evaluate its performance in finding optimal solutions against the previously developed literature methods. Results showed the developed method's superiority in finding a better optimal set of solutions in a reasonable processing time.

Originality/value

The novelty of the proposed method lies in its capacity to consider resource planning and project scheduling under uncertainty simultaneously while accounting for activity splitting.
Developing a measurement of employee learning agility
Authors: Lee Jinju , Song Ji Hoon
Published: June 2021

Purpose

The purpose of this study is to develop a reliable and valid measurement of employee learning agility for use in human resources development.

Design/methodology/approach

This paper analyzed a total of 365 cases collected from Korean organizations. This paper conducted exploratory factor analysis, confirmatory factor analysis and Rasch analysis to validate the measurement. This paper conducted a measurement invariance (MI) test to confirm the generalizability of the measurement and used Harman’s single factor test to assess the common method variance (CMV).

Findings

This paper derived a learning agility measurement with six subfactors (Cronbach’s α = 0.893). This paper verified that it could be applied equally to supervisors and subordinates using an MI test. Factor analysis confirmed the feasibility of CMV. Based on I-ADAPT theory, the learning agility measurement can be applied to assess not only leader competency but also general employee competency.

Research limitations/implications

Practitioners may use this model of learning agility for developing competency-based training programs and evaluations. This study is meaningful because it extends the concept of learning agility. In particular, the MI test indicated that there are no differences between supervisors and employees regarding the utility of the concept.

Originality/value

This study is meaningful because it extends the concept of learning agility. In particular, the MI test indicated that there are no differences between supervisors and employees regarding the utility of the concept. The concept in this paper is distinguished from other studies by applying the Rasch model from an item response theory perspective.
Natural convection in a horizontal annular sector containing heat-generating porous medium
Authors: Machado dos Santos Beatriz , de Sá Ludimila Silva Salles , Su Jian
Published: June 2021

Purpose

The purpose of this work is to propose the generalized integral transform technique (GITT) for the investigation of two-dimensional steady-state natural convection in a horizontal annular sector containing heat-generating porous medium.

Design/methodology/approach

GITT was used to investigate steady-state natural convection in a horizontal annular sector containing heat-generating porous medium. The governing equations in stream function formulation are integral transformed in the azimuthal direction, with the resulting system of nonlinear ordinary differential equations numerically solved by finite difference method. The GITT solutions are validated by comparison with fully numerical solutions by finite difference method, showing excellent agreement and convergence with low computational cost.

Findings

The effects of increasing Rayleigh number are more noticeable in stream function, whereas less significant for temperature. With decreasing annular sector angle from π to π/6, a reduction in the maximum temperature and stream function was noticed. While the two counter-rotating vortical structure is common for all annular sector angles investigated, the relative size of the two vortices varies with decreasing sector angle, with the vortex near the outer radius of the cavity becoming dominant. The annular sector angle affects strongly the maximum temperature and the partition of heat transfer on the inner and outer surfaces of the annular sector with heat-generating porous medium.

Originality/value

The strong effects of the annular sector angle on natural convection in annular sectors containing heat-generating porous medium are investigated for the first time. The proposed hybrid analytical–numerical approach can be applied in other convection problems in cylindrical or annular configurations, with or without porous medium. It shows potential for applications in practical convection problems in the nuclear and other industries.
Millennial social media users' intention to travel: the moderating role of social media influencer following behavior
Authors: Han Joyce , Chen Han
Published: June 2021

Purpose

Social media (SoMe) influencer marketing is a popular practice. The current study examines the interplays between SoMe influencers' source credibility, Millennial users' attitudes and intention to travel. It further investigates the moderating role of SoMe influencer following behavior on the aforementioned relationships.

Design/methodology/approach

A total of 212 useable responses were collected through an online survey. Structural equation modeling and hierarchical multiple regressions were employed for hypotheses testing.

Findings

Results indicated that source credibility had a significantly positive influence on the SoMe users' attitudes, which in turn was positively associated with the intention to visit the endorsed destination. Moreover, both relationships were strengthened for SoMe influencer followers than for nonfollowers.

Originality/value

The study expanded the source credibility theory to the use of SoMe influencer marketing on travel destinations among Millennial SoMe users. In addition, the research applied the self-determination theory to fill the gap in literature by examining the moderating role of SoMe influencer following behavior.
Unraveling the complex nexus of punitive supervision and deviant work behaviors: findings and implications from hospitality employees in Pakistan
Authors: Sarwar Aisha , Muhammad Lakhi , Sigala Marianna
Published: June 2021

Purpose

The study adopts the conservation of resources (COR) theory for providing a better theoretical understanding of punitive supervision as an antecedent of employees’ minor deviant behaviors (namely, employee time theft and knowledge hiding) via creating cognitive mechanisms (employees’ perceived incivility). The purpose of this paper is to examine the moderating role of employees’ RESILIENCY on employees’ ability to buffer the impacts of punitive supervision.

Design/methodology/approach

Data was gathered from 265 frontline hospitality employees in Pakistan. A survey was administered in person to establish trust and rapport with employees and so, collect reliable data.

Findings

The findings confirmed a direct and mediated impact of punitive supervision on employee minor deviant behaviors via creating perceived incivility. The moderating role of employees’ resiliency was also confirmed, as the employees’ resiliency helped them mitigate the impact of punitive supervision on perceived incivility.

Research limitations/implications

Data was collected from employees’ perceptions working in one industry and cultural setting. As employees’ perceptions (influenced by their cultural background) significantly affect their interpretations and reactions to punitive behavior, future research should validate and refine the findings by collecting data from a wider and diversified cultural and industry setting.

Practical implications

The findings provide theoretical explanatory power of the drivers and the contextual factors leading to minor employee deviant behaviors. The findings guide managers on how to develop pro-active and re-active strategies for deterring the occurrence and eliminating the consequences of punitive supervision.

Originality/value

This study contributes to the literature in multiple ways. It identifies and validates punitive supervision as an antecedent of Deviant Work Behavior (DWB). It provides a theoretical underpinning for explaining how punitive supervision spurs cognitive mechanisms, which in turn drive DWB. It also studies the nexus between destructive supervision and its outcomes in its entirety by studying the mediated and the moderating impacts of punitive supervision and perceived incivility, respectively.
Country-of-origin cues: effects of country-related affect and product association on consumer responses to hospitality firms
Authors: Li Dongmei , Xie Lishan
Published: June 2021

Purpose

This paper aims to investigate the impacts of country-of-origin (COO) cues, country-related affect (CRA) and country-related product associations (CRPA) on consumers’ intention to purchase hotel services.

Design/methodology/approach

A survey of 305 respondents was conducted. Mediation and conditional process tests were performed to examine the proposed theoretical framework.

Findings

The results suggest that CRA is positively correlated with consumer trust, which, in turn, affects purchase intention. For consumers with a high (vs low) level of consumer ethnocentrism (CE), the effect of CRA on trust is weaker. CRPA is positively correlated with both consumer trust and price perception, which, in turn, affect purchase intention. For consumers with rich subjective knowledge (SK) of hotel services, the effect of CRPA on price perception is weaker. The effects of COO stereotypes and the moderation effects of CE and SK hold after controlling for consumers’ age, gender, income, education and objective knowledge.

Practical implications

Hospitality practitioners can make use of different types of country-related information to communicate effectively with consumers in a global environment.

Originality/value

This research is the first to discover the different mechanisms underlying different types of COO and the boundary conditions on these effects.

Authors: Leite Carla V. , Almeida Ana Margarida
Published: June 2021

Purpose

This research proposes a framework to guide the development and analysis of digital interventions, namely, through mobile applications, regarding labor and birth. By complying with current scientific evidence, this paper aims to contribute to the safeness and completeness of perinatal health education targeting expectant parents.

Design/methodology/approach

A content analysis was conducted on a document containing World Health Organization guidelines for intra-partum, considering the following categories: timeframe, care options, category of recommendation, to create a data set clearly distinguishing between recommendations and non-recommendations. Context-specific and research-context recommendations, details from dosages, measurements and timings, infant care and non-immediate postpartum topics were considered out of the scope of this study.

Findings

The results were summarized in a table, ready to be used as a data set, including the following 16 care options ranging from health, well-being and/or rights: respect, communication, companionship, pregnant person’s monitoring, status, fetal monitoring, pain relief, pain management, amenities, labor delay prevention, progress, freedom of choice, facilitation of birth, prevention of postpartum hemorrhage, umbilical cord care and recovery. These were distributed across six timeframes: always, admission, first, second and third stage of labor and immediate postpartum. In addition, recommendations and non-recommendations are displayed in different columns.

Originality/value

This transdisciplinary research intends to contribute to: future research on perinatal education; the creation of digital interventions, namely, m-health ones, targeting expectant parents by providing a framework of content coverage; the endorsement of the rights to Information and to decision-making. Ultimately, when put into practice, the framework can impact self-care through access to perinatal education.
Top management commitment and lean team members’ prosocial voice behaviour
Authors: Latif Mohammad Abdul , Vang Jan
Published: June 2021

Purpose

Top management commitment (TMC) and prosocial voice behaviour in Lean teams are vital for the successful Lean implementation. This study aims to investigate how TMC influences Lean team members’ prosocial voice behaviour and how such changed voice behaviour affects the outcome of Lean implementations.

Design/methodology/approach

The authors have used a qualitative research methodology to examine six dimensions of TMC (communication, involvement, support, empowerment, encouragement and monitoring) in two ready-made garment (RMG) factories in Bangladesh. Operational performance was measured by efficiency, quality, value stream mapping, single-minute exchange dies and 5S scores. Occupational Health and Safety (OHS) was assessed by acceptable head and back positions, machine safety, use of masks and housekeeping.

Findings

The findings reveal that TMC influences Lean team members' voice behaviour positively and, thereby, company's performance. Six dimensions of TMC are all critical for mobilizing prosocial voice, which then improves productivity, OHS and enhancing employee capacity and job satisfaction.

Research limitations/implications

This research involved two sewing lines in two RMG factories in Bangladesh. Cross-sector and large-scale international quantitative research is also needed.

Practical implications

This research shows how TMC and Lean problem-solving teams can mobilize employee voice.

Originality/value

Employee voice is a central issue in the implementation of Lean. To the best of the author’s knowledge, for the first time, the authors show how the six dimensions of TMC influence Lean team members’ voice behaviour in the workplace and thereby how prosocial voice affects team performance.
Founder CEOs, business groups and firm value: evidence from an emerging market
Authors: Kim Woo Sung , Kiymaz Halil
Published: June 2021

Purpose

The impact of founder CEOs on firm value continues to be debated in the finance literature. While earlier studies suggest that founding family ownership and founding CEO structure create less value than public ownership, later studies provide contradicting evidence. This study examines how founder CEOs affect firm value in the business group context while controlling for firm-specific variables and various CEO characteristics.

Design/methodology/approach

The authors use a sample of publicly listed Indian firms from 2010 to 2015 with 997 firm-year data observations. While 306 of these are in business groups, the remaining 691 are in a nonbusiness group. The authors also divide the sample into various sector subgroups, including materials (170), industrials (198), consumer (422) and others (198). They use two different models, including the fixed effect model (FEM) and pooled generalized method of moments (GMM) model to run regressions.

Findings

The authors find that firms with founder CEOs have lower firm value than those with nonfounder CEOs. These results show the importance of the role of founder CEOs in the Indian business groups. The authors further find a positive relationship between founder CEO and business group interaction variable, showing that an increase in founder CEO (or business group) increases the significance effect of business group (founder CEO) on firm performance. After separating the sample business and nonbusiness groups, the relationship between founder CEOs and firm value in both groups remains negative. Using various firm-specific control variables, the authors find that highly leveraged and smaller firms experience lower Tobin's Q. In contrast, firms with more investment in research and development perform better. Among CEO characteristics, the authors find that firms with highly educated CEOs do not perform well, while firms with older CEOs do better. Finally, they find that CEO tenure and duality are associated with lower firm performance.

Originality/value

This study adds value by providing evidence on the founder CEOs and firm performance in business groups from a fast-developing emerging market.
Infant sensory patterns: associations with previous perinatal loss, maternal-foetal attachment and postnatal maternal sensory patterns
Authors: Branjerdporn Grace , Meredith Pamela , Wilson Trish , Strong Jenny
Published: June 2021

Purpose

This paper aims to investigate infant sensory patterns and their associations with previous perinatal loss, maternal-foetal attachment and postnatal maternal sensory patterns.

Design/methodology/approach

In a prospective cohort study, women with and without perinatal loss (N= 57) were recruited from an Australian public hospital. Participants were surveyed during pregnancy (maternal-foetal attachment, loss) and again postnatally (maternal/infant sensory patterns). Chi-square tests and logistic regression analyses controlling for previous perinatal loss were conducted with infant sensory patterns as outcome variables.

Findings

“More than typical” infant low registration was associated with poorer quality of maternal-foetal attachment. “More than typical” infant sensory seeking was associated with previous perinatal loss and higher levels of maternal sensory seeking. “More than typical” infant sensory sensitivity was linked with previous perinatal loss, poorer quality of maternal-foetal attachment and higher maternal low registration. “More than typical” infant sensory avoidance was associated with poorer quality of maternal-foetal attachment and higher levels of maternal sensory sensitivity.

Practical implications

To support more typical infant sensory patterns, results point to the potential benefit of occupational therapists supporting pregnant women with previous perinatal loss; facilitating favourable maternal-foetal attachment; and educating new mothers on how their sensory patterns impact on interactions with their infant. Sensory modulation strategies that consider the sensory patterns of both mother and infant may be beneficial to promote engagement in co-occupations.

Originality/value

These findings are the first to suggest that previous perinatal loss, poorer quality of maternal-foetal attachment and higher levels of maternal postnatal sensory patterns represent risk factors for infant sensory patterns that are “more than typical.”

Learning to work from home: experience of Australian workers and organizational representatives during the first Covid-19 lockdowns
Authors: Marzban Samin , Durakovic Iva , Candido Christhina , Mackey Martin
Published: June 2021

Purpose

This paper aims to provide a snapshot of workers’ experience while working from home (WFH) during the Australian lockdown in the middle of the Covid-19 pandemic. It focuses on lessons to inform organizations, employees and the design of the workspaces post-2020, human, organizational and environmental considerations may affect satisfaction, productivity and health.

Design/methodology/approach

Two separate surveys were designed for this study to target Australian organizations and knowledge workers. Participants included 28 organizations and 301 employees, and descriptive and correlational analyses were conducted.

Findings

Organizations stated productivity losses, maintaining culture and workplace health and safety concerns with WFH setup while employees were more concerned about their social interactions, internet connectivity and increased workload. Employees also found the social aspects of WFH challenging and disclosed that face-to-face interactions with their colleagues was the most important reason they wanted to return to the office. High level of trust and value was reported amongst the organizations and workers.

Originality/value

In the scarcity of academic literature around negative and positives of the WFH experiment during the COVID-19 pandemic, the main sources of information have been industry-focused reports. This study aims to contribute to this knowledge gap by identifying positives and negative aspects of WFH during the first wave of lockdowns in Australia in 2020 from the organization and workers’ perspective, including human, organizational and environmental considerations.
Entrepreneurial marketing and bank performance in Egypt: is environmental turbulence a missing link?
Authors: Hilal Omnia Abdelazeem , Tantawy Ahmed Adel
Published: June 2021

Purpose

Current research argues that there is a positive relationship between entrepreneurial marketing (EM) and business performance. However, this relationship has only been discussed in a relatively stable environmental situation and it is not clear whether such a relationship remains positive during environmental turbulence (ET) and whether organizations adopting EM activities during such turbulence, will change their behavior to enhance their performance. Thus, this study aims to examine the relationship between EM and the performance of Egyptian banks. Furthermore, building upon environmental contingency theory, this study examined the moderating role of ET on the relationship between EM and the performance of banks in Egypt.

Design/methodology/approach

Data were collected during the period March–June 2020 using a sample of 358 employees working in 20 banks in Egypt. Online surveys and self-administered questionnaires were used to collect the required data during the COVID-19 pandemic. The hypotheses were tested through structural equation modeling using SPSS 25.

Findings

The main results of this study indicated that EM and bank performance are positively related. Results also showed that ET and technological turbulence positively moderates this relationship, i.e. this relationship is more robust in highly turbulent business environments than in more stable environments.

Practical implications

This study provides useful managerial and practical implications. Fruitful insights can be communicated to bank managers in Egypt on the importance of EM and its implications for performance. With an increased understanding of EM, bank managers will come to understand that EM is critical for the sustainability and development of their banks.

Originality/value

An extensive review of the existing research material indicates that this is the first study to examine the relationship between EM and Egyptian banking performance and the moderating role of ET, particularly in large organizations.
The GDP, the US treasury yield and the federal funds rate: who follows whom, when and why?
Authors: Seip Knut Lehre , Zhang Dan
Published: June 2021

Purpose

This study aims to address the fundamental question on how the major players in the economy dynamically interact with each other: among the central bank, the investors in the bond market and the firms and consumers that contribute to the economic growth, who gets information from whom, when and why?

Design/methodology/approach

To answer “who follows whom,” the authors apply a novel technique to examine the lead–lag relations between three time series, the federal funds rate, the treasury yield curve and the gross domestic product (GDP). To investigate “when and why,” the authors combine the lead–lag relations with principal component analysis to cluster economic states that are similar with respect to the eight macroeconomic variables.

Findings

The authors show that during the period 1977–2019, the bond market potentially obtained information from the federal funds rate (61% of the time) and less often (34% of time) from the changes in the GDP. Meanwhile, the funds rate decision by the Federal Reserve seems to lead the economic growth about 63% of the time. The analysis also suggests that the bond market obtained information directly from GDP when unemployment and inflation was high. In addition, the authors find that the federal funds rate was leading the GDP when the GDP deviated from the target value, consistent with the Federal Reserve’s policy of boosting and damping the economy when the GDP growth is low or high, respectively.

Originality/value

This study provides insights into the fundamental questions that have important implications for empirical work on the monetary policy, financial stability and economic activities.
Blockchain in Indian Public Distribution System: a conceptual framework to prevent leakage of the supplies and its enablers and disablers
Authors: Mishra Himani , Maheshwari Prateek
Published: June 2021

Purpose

The purpose of this paper is to propose a conceptual framework for the application of blockchain in the Public Distribution System (PDS) in India to manage the supply of food grains to the targeted beneficiaries. The framework will help prevent diversions and leakages of grains at the warehouse and Fair Price Shop (FPS) level. The paper also identifies the enablers and disablers in the context of the framework.

Design/methodology/approach

This paper will firstly review the previous literature in PDS and blockchain-enabled agricultural and food supply chains. The study then proposes a framework that could be implemented in the PDS in India using blockchain technology.

Findings

The proposed framework provides an effective way to combat corruption, exclusion errors of targeted beneficiaries, leakage of PDS food grains and is cost-effective. The identified enablers and disablers give an insight into the application of blockchain in PDS in India.

Research limitations/implications

The research work may have implications for the Ministry of Food and PDS (Central Government), Food Corporation of India and State Governments to manage the supply of the grains more efficiently and effectively.

Originality/value

The current study caters to the implementation of blockchain technology starting from the warehouse level to the FPSs and consumers and simultaneously connecting them to concerned authorities to ensure transparency and accountability.
Can a formalised model of co-production contribute to empowering indigenous communities in decisions about land use?
Authors: Gillies Alan
Published: June 2021

Purpose

Co-production has been used in public services in the UK areas such as mental health to improve the participation of service users in decisions made about the services traditionally provided for them and done to them. It has also been used in areas such as mental health and to address concerns about the quality of services provided to members of minority communities. Western Australia is currently passing legislation to address the issue of aboriginal cultural heritage management in the context of recent adverse incidents such as the incident where Rio Tinto was responsible for the destruction of the site. This paper aims to show how a formalised model of co-production can assist in the implementation of this legislation.

Design/methodology/approach

This paper considers how effective co-production has been within the domain of mental health services in the UK and then considers whether they are lessons that may be learnt in other contexts. It considers whether concepts from co-production have a role to play in ensuring that the legislation and its implementation are not seen as actions done to or on behalf of the aboriginal communities and if a more structured approach to coproduction can produce a model, which facilitates genuinely collaborative aboriginal heritage management.

Findings

The approach has facilitated the development of a model to monitor and improve collaboration within aboriginal cultural heritage management, which complements existing participatory approaches and enables businesses to demonstrate their legislatory compliance.

Social implications

The study offers an approach, which may be used globally to empower indigenous communities in decision-making in other contexts, such as deforestation in South America and oil and gas exploitation on Inuit and First Nations land in Canada.

Originality/value

The use of co-production concepts and capability modelling is novel in this space.
Teaching a while measuring b: cultural bias in assessing student performance
Authors: Seno-Alday Sandra , Budde-Sung Amanda
Published: June 2021

Purpose

This paper aims to explore the impact of differences in educational traditions on conventions of teaching and learning, and on the measurement of learning outcomes. These are critical issues within the context of business schools that are steeped in one dominant tradition but have a large population of international students previously educated in other traditions. The paper argues that international students face the challenge of satisfactorily demonstrating learning according to foreign conventions that are different from what they would have been accustomed to within the framework of their home educational tradition.

Design/methodology/approach

This study draws on a bilingual literature review to capture differences in educational traditions between Australia and China. It then uses logistic regression to analyze the performance of 800 domestic and international Chinese students across a range of different assessment formats at a large Australian business school.

Findings

The study finds statistically significant differences in the performance of these two student groups on different assessment types. It concludes that the conventions on approaches to the assessment of learning shaped by a specific educational tradition can hamper the effective demonstration of learning among students from other educational traditions.

Originality/value

The paper focuses on issues related to the assessment of learning in multicultural higher education contexts, which has received less attention in the literature compared to issues on teaching approaches in multicultural contexts. The paper also highlights important implications on the validity of the measurement of learning outcomes and on the subsequent impact on graduate recruitment.
The nexus between emotional intelligence and types of knowledge sharing: does work experience matter?
Authors: Malik Shehla
Published: June 2021

Purpose

Owing to limited research exploring the role of emotional constructs on different types of knowledge sharing, this paper aims to examine the impact of emotional intelligence on two different types of knowledge sharing, namely, tacit knowledge sharing and explicit knowledge sharing. Further, this study also attempts to explore the moderating role of work experience between emotional intelligence-knowledge sharing relationship.

Design/methodology/approach

A survey design methodology is used to collect data from 245 employees of global information technology (IT) companies located in India. Structural equation modelling technique was applied to test the hypothesised relationships among the constructs.

Findings

The results indicate that emotional intelligence has a stronger positive effect on tacit knowledge sharing (ß = 0.78, p < 0.001) compared to explicit knowledge sharing (ß = 0.59, p < 0.001). Multigroup analysis results reveal that influence of emotional intelligence on tacit knowledge sharing was stronger for high experience group compared to low experience group. However, no significant differences were found based on work experience for the emotional intelligence-explicit knowledge sharing relationship.

Practical implications

This study suggests suitable interventions that management can adopt to enhance tacit as well as explicit knowledge sharing in global IT organisations.

Originality/value

This study provides a comprehensive understanding of the differences that exists between tacit and explicit knowledge sharing and highlights the impact of emotional intelligence on these distinctively. It advances knowledge sharing literature and brings uniqueness by exploring the moderating role of work experience on emotional intelligence-knowledge sharing relationship in a non-western setting.
Implications of recent reforms to auditor reporting requirements in Australia
Authors: Rahaman Md Mustafizur , Chand Parmod
Published: June 2021

Purpose

This paper aims to address a topical and controversial issue, namely, the degree of conformity with the new auditor reporting requirements in Australia and the extent of variations in the reporting of key audit matters (KAMs) by Australian firms.

Design/methodology/approach

This paper compares the 64 elements identified in the applicable standards with the auditor’s report from the sampled companies to determine the degree to which the top 200 firms listed on the Australian Stock Exchange are complying with the requirements of the new audit report. This paper investigates KAM disclosures within and across industries.

Findings

The results indicate that there is a high degree of conformity with the new reporting framework, yet significant variations in the contents of the report, particularly in KAM disclosures. This paper observes that the number of KAMs and their extent of disclosure generally varies within industries. The types of KAMs presented vary both within and across industries. This paper further provides evidence that auditors have a tendency of not disclosing negative KAMs and tend to avoid negative wordings when describing KAMs. This paper also finds that there are significant differences in the placement of various types of KAMs in the audit report.

Practical implications

These findings have important policy implications for the standard-setters, regulators, auditors and users of financial reports on the adequacy of the new auditor reporting framework.

Originality/value

This study is one of the first to examine the degree of conformity with the new audit reporting model in Australia.
Auxetic structures fabricated by material extrusion: an experimental investigation of gradient parameters
Authors: Vyavahare Swapnil , Teraiya Soham , Kumar Shailendra
Published: June 2021

Purpose

This paper aims to focus on studying the influence of gradient parameters, namely, thickness coefficient, length coefficient and height ratio of auxetic structure on responses such as strength, stiffness and specific energy absorption (SEA) under compressive loading. Optimization of significant parameters is also performed to maximize responses. Further, efforts have also been made to develop regression models for strength, stiffness and SEA of auxetic structure.

Design/methodology/approach

Central composite design of response surface methodology is used for planning experiments. Auxetic structures of acrylonitrile butadiene styrene (ABS) and poly-lactic acid (PLA) materials are fabricated by the material extrusion (ME) technique of additive manufacturing. Fabricated structures are tested under in-plane uniaxial compressive loading. Grey relational analysis is used for the optimization of gradient parameters of the unit cell of auxetic structure to maximize responses and minimize weight and time of fabrication.

Findings

From the analysis of variance of experimental data, it is found that the compressive strength of auxetic structures increases with a decrease in length coefficient and height ratio. In the case of ABS structures, stiffness increases with a decrease in thickness coefficient and length coefficient, while in the case of PLA structures, stiffness increases with a decrease in length coefficient and height ratio. SEA is influenced by length coefficient and thickness coefficient in ABS and PLA structures, respectively. Based on the analysis, statistical non-linear quadratic models are developed to predict strength, stiffness and SEA. Optimal configuration of auxetic structure is determined to maximize strength, stiffness, SEA and minimize weight and time of fabrication.

Research limitations/implications

The present study is limited to re-entrant type of auxetic structures made of ABS and PLA materials only under compressive loading. Also, results from the current study are valid within a selected range of gradient parameters. The findings of the present study are useful in the optimal selection of gradient parameters for the fabrication of auxetic structures of maximum strength, stiffness and SEA with minimum weight and time of fabrication. These outcomes have wide applications in domains such as automotive, aerospace, sports and marine sectors.

Originality/value

Limited literature is available on studying the influence of gradient parameters of ME manufactured auxetic structure of ABS and PLA materials on responses, namely, strength, stiffness and SEA under compressive loading. Also, no work has been reported on studying the influence of gradient parameters on mechanical properties, weight and time of fabrication of auxetic structures. The present study is an attempt to fulfil the above research gaps.

Purpose

The purpose of this study is to examine the role of financial governance practices in influencing both financial management and Islamic work ethic practices to affect Islamic social enterprises (ISEs) accountability.

Design/methodology/approach

Questionnaires were administered to financial officers of 102 Malaysian ISEs. Data was analysed using Smart-PLS to examine the relationships between financial management, Islamic work ethic, financial governance and accountability.

Findings

Results of this study indicate direct relationship only exist between Islamic work ethic and accountability. The relationship between financial management and accountability are indirect through financial governance. Hence, the data proves that financial governance has a mediating role on both the relationships between financial management and Islamic work ethic with the accountability of the ISEs.

Research limitations/implications

The study has highlighted the greater role of financial management, Islamic work ethic and financial governance practices over accountability to achieve public trust, especially for Malaysian ISEs.

Practical implications

ISEs need to have good financial governance practices besides financial management and Islamic work ethic practices to achieve good accountability.

Originality/value

The study contributes to the field of management and social accounting by providing empirical evidence on the ISEs practices specifically on financial management, Islamic work ethic, financial governance and accountability. This framework thus presents amongst the first attempts in studying accountability issues in ISEs.

Evolution of virulence traits from adaptation to environmental niches other than the host is probably a common feature of marine microbial pathogens, whose knowledge might be crucial to understand their emergence and pathogenetic potential. Here, we report genome sequence analysis of a novel marine bacterial species, Vibrio bathopelagicus sp. nov., isolated from warm bathypelagic waters (3309 m depth) of the Mediterranean Sea. Interestingly, V. bathopelagicus sp. nov. is closely related to coastal Vibrio strains pathogenic to marine bivalves. V. bathopelagicus sp. nov. genome encodes genes involved in environmental adaptation to the deep‐sea but also in virulence, such as the R5.7 element, MARTX toxin cluster, Type VI secretion system and zinc‐metalloprotease, previously associated with Vibrio infections in farmed oysters. The results of functional in vitro assays on immunocytes (haemocytes) of the Mediterranean mussel Mytilus galloprovincialis and the Pacific oyster Crassostrea gigas, and of the early larval development assay in Mytilus support strong toxicity of V. bathopelagicus sp. nov. towards bivalves. V. bathopelagicus sp. nov., isolated from a remote Mediterranean bathypelagic site, is an example of a planktonic marine bacterium with genotypic and phenotypic traits associated with animal pathogenicity, which might have played an evolutionary role in the origin of coastal marine pathogens.
Doom and Gloom: The Future of the World at the End of the Eighteenth Century
Authors: Weber Lina
Published: June 2021

This article challenges the widely held assumption that Thomas Robert Malthus was a lonely pessimist in the late eighteenth century. Interpreting the sources that Malthus had used to write his Essay on the Principle of Population as predictions of the future, the article argues that Malthus inherited a sense of looming doom from his predecessors. In the second half of the eighteenth century, David Hume, Adam Smith, Richard Price, and Thomas Paine predicted Britain's ruin through national bankruptcy. Although Malthus, too, expressed anxiety about excessive growth, he changed the parameters by worrying about overpopulation, rather than overspending. By considering Malthus in the context in which he originally formulated his famous principle of population, this article sheds new light on what he was doing when he first published his Essay in 1798.
Driving lateral collaboration effectiveness across multinational enterprises: The antecedents and consequences
Authors: Chen Iris S. Y.
Published: June 2021

In the face of increasing global uncertainty, multinational enterprises (MNEs) have turned to downsizing to maintain profitability while emphasizing lateral collaboration to increase productivity. Here, we establish a conceptual framework and examine from a macro‐to‐micro perspective how the growing subjects of subsidiary role change, team alignment and employee engagement impact lateral collaboration. We used structural equation modelling to analyse the results of 252 surveys given to MNE subsidiaries in the Taiwanese banking industry and found that employee engagement was central to driving lateral collaboration effectiveness, indicating that the subsidiary role is critical for boundary‐spanning activities and building bridges between various teams. These activities in turn enhance subsidiary performance and lead to better people development. Our findings demonstrate that bundling employee engagement with human resource practices is a strategic way of positioning for the evolution of subsidiary management.
Impact of Wetlands Loss and Migration, Induced by Climate Change, on Chesapeake Bay DO Standards
Authors: Cerco Carl F. , Tian Richard
Published: June 2021

A predictive wetlands module is added to an existing eutrophication model of Chesapeake Bay in order to evaluate the impact of wetlands loss and migration on dissolved oxygen (DO) standards. Loss and migration are expected due to increases in sea level associated with climate change. The module calculates fluxes of carbon, nitrogen, and phosphorus between wetlands and the adjacent water column. Calculations are performed for a range of sea‐level increments up to 1 m. Wetlands areas, as a function of sea level, are obtained from an existing, independent, model applied to Chesapeake Bay. The results indicate two risks to DO standards. The first results from wetlands loss and simultaneous reductions in nutrient removal and burial by wetlands. Reduction in burial is the equivalent of a nutrient load increase and produces diminished DO in deep water and deep channel portions of the Bay. The second risk results from wetlands migration into upland areas adjoining shallow embayments and tidal fresh waters of the Bay. An increase in wetlands area in these regions may result in diminished DO concentration in adjacent open water due to direct wetlands respiration.
