Abstract

Purpose

A stylized fact in finance literature is the belief in positive relationship between ex ante return and risk. Hence, a rational investor, by utility preference axiom can only consider committing fund in asset which promises commensurate higher return for higher risk. Questions have been asked as to whether this holds true across securities, sectors and markets. Empirical evidence appears less convincing, especially in developing markets. Accordingly, the author investigates the nature of reward for taking risk in the Nigerian Capital Market within the context of individual assets and markets.

Design/methodology/approach

The author employed ex post design to collect weekly stock prices of firms listed on the Premium Board of Nigerian Stock Exchange for period 2014–2022 to attempt to answer research questions. Data were analyzed using a unique M Vec TGarch-in-Mean model considered to be robust in handling many assets, and hence portfolio management.

Findings

The study found that idea of risk-expected return trade-off is perhaps more general than as depicted by traditional finance literature. The regression revealed that conditional variance and covariance risks reveal minimal or no differences in sign and sizes of coefficients. However, standard errors were also found to be large suggesting somewhat inconclusive evidence of existence of defined incentive structure for taking additional risk in the market.

Originality/value

In terms of choice of methodology and outcomes, this research adds substantial value to body of knowledge. The adapted multivariate model used in this paper is a rare approach especially for management of portfolios in developing markets. Remarkably, the research found empirical evidence that positive risk-expected return trade-off, as known in mainstream literature, is not supported especially using a typical developing country data.

This study aims to examine the mediating role of audit seasonality on the association between audit fees and audit quality in Nigerian deposit money banks.

Abstract

Purpose

This study aims to examine the mediating role of audit seasonality on the association between audit fees and audit quality in Nigerian deposit money banks.

Design/methodology/approach

The sample comprises 14 banks with annual financial statements between 2008 and 2020. The modified Baron and Kenny’s (1986) causal mediation model by Iacobucci et al. (2007) through the use of bootstrapped partial least square structural equation modelling and Sobel’s (1986) z-test is adopted to achieve this study’s objective.

Findings

The results of the causal mediation analysis show evidence of a fully mediating role of audit seasonality in the association between audit fees and audit quality in the Nigerian banking industry.

Research limitations/implications

This study extends the body of knowledge by demonstrating how audit fees influence audit quality through audit seasonality as a mediator in line with the job demands-and resources and conservation of resources theories. Regulatory authorities should be wary of policies that will further increase the workload of already burdened personnel of audit firms as the uniform fiscal year-end of 31 December introduced in the Nigerian banking system has unintended consequences on audit fees and audit quality.

Originality/value

To the best of the author’s knowledge, this is one of the first studies to provide evidence on the indirect association between audit fees and audit quality.

Abstract

Purpose

This case study, within the context of boundaryless and protean career development frameworks, investigates linguistic profiling and how code-switching is used to mitigate its impact on Black leaders during their careers. The experiences of Black women coaches and the coaching support they offered Black women clients in code-switching, leadership and career advancement are described. The value of leadership coaching when used to navigate these career progression challenges is emphasized.

Design/methodology/approach

The study employed a multiple-case study approach of two Black women leadership coaches.

Findings

The findings of this study illustrate the understanding of code-switching and the coaching techniques employed by two Black women leadership coaches. Sage focused on educational strategies, offering historical contexts and resources, while Khadijah leaned on empathy-driven methods, using storytelling to evoke reflection. Both coaches emphasized creating safe spaces for open dialog, encouraged clients to reconsider their actions and values regarding code-switching challenges and sought to prompt clients towards authenticity while navigating career spaces effectively.

Practical implications

Additional strategies for coach practitioners include cultivating trust and a safe environment; active listening; challenging biases and assumptions; contextual understanding; empowering authentic self-expression; fostering skill development; challenging stereotypes; promoting autonomy and flexibility and adopting cross-cultural sensitivity, humility and competence. These practical coaching strategies bridge the gap in career development research by demonstrating how race-conscious strategies can promote workplace inclusivity and promulgate career development.

Originality/value

The study underscores the problem of linguistic profiling, the complexity of code-switching and implications for Black women navigating their career journey within professional spaces. It highlights the significance and value of tailored leadership coaching strategies to promote career advancement. This study addresses the gap in career development research related to linguistic profiling avoidance strategies for workplace inclusivity.

Abstract

Purpose

This study aims to identify the political alignment and political activity of the 11 Presidents of Britain’s most important scientific organisation, the Royal Society of London, in its early years 1662–1703, to determine whether or not the institution was politically aligned.

Design/methodology/approach

There is almost no information addressing the political alignment of the Royal Society or its Presidents available in the institution’s archives, or in the writings of historians specialising in its administration. Even reliable biographical sources, such as the Oxford Dictionary of National Biography provide very limited information. However, as 10 Presidents were elected Member of Parliament (MP), The History of Parliament: British Political, Social and Local History provides a wealth of accurate, in-depth data, revealing the alignment of both.

Findings

All Presidents held senior government offices, the first was a Royalist aristocrat; of the remaining 10, 8 were Royalist or Tory MPs, 2 of whom were falsely imprisoned by the House of Commons, 2 were Whig MPs, while 4 were elevated to the Lords. The institution was Royalist aligned 1662–1680, Tory aligned 1680–1695 and Whig aligned 1695–1703, which reflects changes in Parliament and State.

Originality/value

This study establishes that the early Royal Society was not an apolitical institution and that the political alignment of Presidents and institution continued in later eras. Furthermore, it demonstrates how the election or appointment of an organisation’s most senior officer can be used to signal its political alignment with government and other organisations to serve various ends.

Abstract

Purpose

Despite the popularity of gig employment amid the changing business landscape, gig scholarship is somewhat limited and the untold reality about gig is yet to be fully revealed. This study aims to critically address the nature of gig employment, its ambiguities, evolution, theoretical premises and the appropriate future road ahead.

Design/methodology/approach

This paper adopts a dual analytical approach – bibliometric and thematic analyses. After incorporating the exclusion–inclusion criteria, the authors identified 2,135 articles for the bibliometric analyses by using VOSviewer. Additionally, for the deep-delving synthesis, the authors conducted thematic analyses following Braun and Clarke (2006), based on 351 papers.

Findings

The findings revealed that gig work, in its different forms, is emerging as an alternative work arrangement with respect to the future of work. This study also identified multilevel perspectives of gig employment along with its holistic nomological network. Finally, this study offers some critical research directions that should help enhance the theoretical and practical strengths of this nascent scholarship in future.

Research limitations/implications

The review findings are limited in nature owing to the paucity of quality research papers published in the said domain.

Practical implications

The paper brings more clarity to what gig is and isn’t, along with its critical perspectives from multilevel lenses.

Originality/value

This paper identifies critical perspectives related to gig work and suggests appropriate directions for future gig work related scholarship.

Abstract

Purpose

This study aims to address a systematic literature review (SLR) using bibliometrics on the relationship between academic integrity and artificial intelligence (AI), to bridge the scattering of literature on this topic, given the challenge and opportunity for the educational and academic community.

Design/methodology/approach

This review highlights the enormous social influence of COVID-19 by mapping the extensive yet distinct and fragmented literature in AI and academic integrity fields. Based on 163 publications from the Web of Science, this paper offers a framework summarising the balance between AI and academic integrity.

Findings

With the rapid advancement of technology, AI tools have exponentially developed that threaten to destroy students' academic integrity in higher education. Despite this significant interest, there is a dearth of academic literature on how AI can help in academic integrity. Therefore, this paper distinguishes two significant thematical patterns: academic integrity and negative predictors of academic integrity.

Practical implications

This study also presents several contributions by showing that tools associated with AI can act as detectors of students who plagiarise. That is, they can be useful in identifying students with fraudulent behaviour. Therefore, it will require a combined effort of public, private academic and educational institutions and the society with affordable policies.

Originality/value

This study proposes a new, innovative framework summarising the balance between AI and academic integrity.

This study aims to examine how couplepreneurs foster an entrepreneurial mindset in their kids.

Abstract

Purpose

This study aims to examine how couplepreneurs foster an entrepreneurial mindset in their kids.

Design/methodology/approach

A qualitative research approach with semi-structured interviews was used as the data collection technique. Narrative analysis was conducted on a sample of 20 couplepreneurs in Mthatha, South Africa.

Findings

Narratives of how couplepreneurs foster an entrepreneurial mindset in their kids included purchasing toys and games for kids that encourage entrepreneurship; competition and team activities among kids that are related to entrepreneurship; the piggy bank; encouraging kids to read entrepreneurial books; and kid entrepreneur showcases.

Research limitations/implications

Sample size challenges are a notable limitation, including research being conducted in only one province of South Africa. Caution is advised when attempting to generalise the results to other contexts.

Practical implications

Understanding the strategies used by couplepreneurs to instil an entrepreneurial mindset in children can help parents to influence and encourage their children's entrepreneurial growth, resulting in more creative and innovative people who make a positive contribution to society, economy and the community.

Originality/value

While there is a body of literature on couple entrepreneurship, there are shortcomings in studies examining how coupleprenuers in African countries instil an entrepreneurial mindset in their children. As a result, this study aims to complement the current corpus of African literature on entrepreneurship, particularly in the context of South Africa.

Abstract

Purpose

The success of the organization depends on its sustainability and growth in the competitive market. Retention and attraction of talent in the organization are strongly associated with organizational performance. Employer branding is an outcome activity that helps organizations show their strength to attract and retain talent. Talent management practices are mostly essential in the current context for retaining talent. This study aims to explore and identify the contributing factors in efficient talent management and to examine whether the factors contributing to employer branding differ concerning different demographic profiles of the employees for information technology organizations.

Design/methodology/approach

Data were collected from 617 adult participants using an 85-item questionnaire on talent management comprising 25 domains, developed for the present study.

Findings

Principal component analysis of the data indicated that 20 different factors make an impact in developing strong talent management practices. Three broad areas were identified, namely, personal benefits and growth, transparent organizational culture and social commitment of the organizations.

Research limitations/implications

Present research has not taken care of few other factors associated with the organization where employees’ retention gets adversely effected such as evaluation of performance and compensation management, training and development, etc. So, future research can be conducted these areas. These aspects are also required to be incorporated in future research.

Practical implications

Several implications of the present research can be presented in the following areas. It is found in the present research that the effectiveness of the talent management system mostly depends on personal benefits and growth, organizational culture and climate and the organizational out. Apart from the academic implications of the present research, practical implications of the present study cannot be ignored. The components and elements of the talent management in the perspectives employer branding can also appropriately applied by the organizations.

Originality/value

The contribution of the study lies in exploring and identifying three important aspects of the organization in talent management. Findings will have implications for different organizations in understanding, developing and implementing policies related to employer branding and talent management.

Abstract

Purpose

This paper aims to explore how sustainability practices were implemented in a higher education institution within a local setting in the Gulf and Arab Emirates Region. This study examined the impact of social and cultural requirements on the development of the master plan for the New Kuwait University campus with regards to sustainability to illustrate how current social and cultural requirements impact the design of a future learning environment whilst highlighting the essential role of organisational actors in this implementation process.

Design/methodology/approach

Using an in-depth case study approach, the authors conducted 21 semi-structured interviews with educators and administrative staff who had been involved in the sustainability implementation process at Kuwait University. These participants were involved at different stages in the implementation of a major sustainability project at Kuwait University. The interviews were further supplemented by analysing supporting documents and communications.

Findings

The analysis reveals that sustainability was embedded in a narrative that was repeated at the practice level; this directed the setting of objectives for the project and its various sub-tasks. It also helped actors to develop their understandings of practice and the importance of social emotions, self-intentions and patterns of culture in the process. This study further reveals that participants mainly focused on environmental issues regarding saving paper/electricity and overlooked aspects of a wider concepts and core values of sustainability, and there is a significant amount of lack of knowledge and awareness on matters about sustainability, especially with the understanding of its definition.

Originality/value

This study draws on practice-organisation framework used by Schatzki (2002, 2010), suggesting that sustainability implementation is a process led by rules, practical understanding, general understanding and teleoaffective structures, to highlight the role of agency and change among various actors in implementing sustainability. A practice-theory framing is used to signpost the roles played by various actors in establishing goals and tasks for the project while taking account of local understanding and independence in the implementation of sustainability practices. Engaging with practice theory framework offers us theoretical basis that is fundamentally different from the theories of interaction-oriented approaches in sustainable design.

Abstract

Purpose

Higher energy conversion efficiency of internal combustion engine can be achieved with optimal control of unsteady in-cylinder flow fields inside a direct-injection (DI) engine. However, it remains a daunting task to predict the nonlinear and transient in-cylinder flow motion because they are highly complex which change both in space and time. Recently, machine learning methods have demonstrated great promises to infer relatively simple temporal flow field development. This paper aims to feature a physics-guided machine learning approach to realize high accuracy and generalization prediction for complex swirl-induced flow field motions.

Design/methodology/approach

To achieve high-fidelity time-series prediction of unsteady engine flow fields, this work features an automated machine learning framework with the following objectives: (1) The spatiotemporal physical constraint of the flow field structure is transferred to machine learning structure. (2) The ML inputs and targets are efficiently designed that ensure high model convergence with limited sets of experiments. (3) The prediction results are optimized by ensemble learning mechanism within the automated machine learning framework.

Findings

The proposed data-driven framework is proven effective in different time periods and different extent of unsteadiness of the flow dynamics, and the predicted flow fields are highly similar to the target field under various complex flow patterns. Among the described framework designs, the utilization of spatial flow field structure is the featured improvement to the time-series flow field prediction process.

Originality/value

The proposed flow field prediction framework could be generalized to different crank angle periods, cycles and swirl ratio conditions, which could greatly promote real-time flow control and reduce experiments on in-cylinder flow field measurement and diagnostics.
