Abstract

Purpose

This study aims to undertake a comprehensive examination of heat transfer by convection in porous systems with top and bottom walls insulated and differently heated vertical walls under a magnetic field. For a specific nanofluid, the study aims to bring out the effects of different segmental heating arrangements.

Design/methodology/approach

An existing in-house code based on the finite volume method has provided the numerical solution of the coupled nondimensional transport equations. Following a validation study, different explorations include the variations of Darcy–Rayleigh number (Ram = 10–104), Darcy number (Da = 10–5–10–1) segmented arrangements of heaters of identical total length, porosity index (ε = 0.1–1) and aspect ratio of the cavity (AR = 0.25–2) under Hartmann number (Ha = 10–70) and volume fraction of φ = 0.1% for the nanoparticles. In the analysis, there are major roles of the streamlines, isotherms and heatlines on the vertical mid-plane of the cavity and the profiles of the flow velocity and temperature on the central line of the section.

Findings

The finding of a monotonic rise in the heat transfer rate with an increase in Ram from 10 to 104 has prompted a further comparison of the rate at Ram equal to 104 with the total length of the heaters kept constant in all the cases. With respect to uniform heating of one entire wall, the study reveals a significant advantage of 246% rate enhancement from two equal heater segments placed centrally on opposite walls. This rate has emerged higher by 82% and 249%, respectively, with both the segments placed at the top and one at the bottom and one at the top. An increase in the number of centrally arranged heaters on each wall from one to five has yielded 286% rate enhancement. Changes in the ratio of the cavity height-to-length from 1.0 to 0.2 and 2 cause the rate to decrease by 50% and increase by 21%, respectively.

Research limitations/implications

Further research with additional parameters, geometries and configurations will consolidate the understanding. Experimental validation can complement the numerical simulations presented in this study.

Originality/value

This research contributes to the field by integrating segmented heating, magnetic fields and hybrid nanofluid in a porous flow domain, addressing existing research gaps. The findings provide valuable insights for enhancing thermal performance, and controlling heat transfer locally, and have implications for medical treatments, thermal management systems and related fields. The research opens up new possibilities for precise thermal management and offers directions for future investigations.

Abstract

Purpose

This study aims to investigate basic/core principles and practical tools behind successful manuscript writing for education journals. Drawing on the insights of journal editors and related literature, this paper seeks to clarify the craft of preparing quality manuscripts to meet the expectations of academic journals.

Design/methodology/approach

This paper uses an interpretivist framework by incorporating a qualitative analysis of the literature with the authors’ experiences to identify key principles and issues in academic publishing. These narratives provide an empirical basis for understanding the mechanics and essence of effective manuscript crafting. The study integrates theoretical knowledge with actionable strategies, focusing on identifying the objectives and processes of writing, determining common challenges and directing readers toward comprehensive resources for guidance in article writing.

Findings

This study reveals that manuscript rejections often transcend technical shortcomings. Issues that are central to nonacceptance include misalignment with a journal’s thematic focus, absence of a coherent and persuasive argument, methodological weaknesses and insufficient evidence underpinning the assertions. Successful publication depends not just on data presentation and adherence to submission norms but also on developing a narrative that enriches the prevailing scholarly discourse. Our findings advocate for manuscripts that strike an appropriate balance between lucidity and analytical rigor, avoid superfluous technical language and express a mix of assertiveness and scholarly modesty.

Originality/value

Although there is literature on academic writing, very few recent articles have been uncovered that probe the intricacies of crafting education manuscripts and point to resources.

Abstract

Purpose

This study investigates the impact of pre-IPO earnings management on investor demand in the Indian IPO market. It also examines whether earnings management by issuer firms affects IPO valuation, a topic that is underexplored in accounting research.

Design/methodology/approach

The study uses the data of 310 IPOs from India during the period 2000–2021. The association between pre-IPO earnings management with investor demand and valuation is tested using cross-sectional ordinary least squares regression models with heteroscedasticity-robust standard errors.

Findings

The study finds that the degree of pre-IPO earnings management impacts retail investor demand, measured as their over-subscription multiple. Pre-IPO earnings management is unrelated to institutional investor bidding. Further, this paper suggests no relation between pre-IPO earnings management and IPO valuation.

Research limitations/implications

Future studies could explore various other forms of earnings management and their impact on investor demand and valuation.

Practical implications

The findings of this study will help the investors and regulators to understand the practice of earnings management among IPO firms and how it is related to IPO demand and valuation.

Originality/value

This study contributes to the existing literature on IPO-earnings management and investor demand by documenting that issuer firms engage in earnings management to influence investor demand, particularly retail investor demand. Analysis of IPO valuation reveals that earnings management is mostly unrelated to IPO valuation, contrary to the general perception in the literature.

Abstract

Purpose

This paper aims to examine the relationship between earnings quality and corporate cash holdings in an emerging economy. Existing literature posits that earnings quality is a result of information asymmetry and firms with lower earnings quality increases cash holdings, to shield the firm from future uncertainties. In this paper, the authors propose a ‘private benefits hypothesis’, which suggests that lower earnings quality is an indicator of opportunism and expropriation of resources in the firm, through tunneling or excessive executive compensations. As a result, firms with lower earnings quality increase cash holdings in their control, to increase their private benefits and to avoid the scrutiny of the external stakeholders. The authors further examine the monitoring role played by institutional investors on cash holdings, with varying degrees of earnings quality.

Design/methodology/approach

This study uses an unbalanced panel data sourced from Prowessdx, from 2000 to 2019. The analysis employs 20,231 firm-year observations from 2,421 firms. Earnings quality is calculated following Dechow and Dichev (2002).

Findings

Empirical analysis confirms that the firms with higher earnings quality reduce cash. Further, institutional investors reduce the cash holdings in firms with higher earnings quality. Institutional investors effectively reduce the cash only in firms with at least 10% of equity shareholding. The results are robust to alternative measures of earnings quality and endogeneity concerns.

Originality/value

This study diverges from the information asymmetry hypothesis in the existing literature on earnings quality and cash holdings and highlights the underlying private benefits hypothesis, that will impact cash holdings. Next, the 10% institutional shareholding is important in the Indian context as it represents the minimum threshold at which block holders can request extraordinary general meetings (Section 100 of the Companies Act 2013) or the involvement of the National Company Law Tribunal (NCLT) (Section 213 of the Companies Act 2013). This study highlights that unlike in Anglo-Saxon economies, institutional investors or other minority shareholders are empowered by the Companies Act 2013 to play a vital role in corporate governance with a mere 10% equity.

Abstract

Purpose

The study examines the IPO resilience grounded on the firm’s intrinsic factors.

Design/methodology/approach

We examine the association of IPO performance and post-listing firm’s performance with issuers' pre-listing financial and qualitative traits using panel data regression.

Findings

IPOs floated in the Indian market from July 2009 to March 31, 2022, evince the notable influence of issuers' pre-IPO fundamentals and legitimacy traits on IPO returns and post-listing earning power. Where the pandemic’s favorable impact is discerned on the post-listing year earning power of the issuer firms, the loss-making issuers appear to be adversely affected by the Covid disruption. Perhaps, the successful listing equipped the issuers with the financial flexibility to combat market challenges vis-à-vis failed issuers deprived of desired IPO proceeds.

Research limitations/implications

High initial returns followed by a declining pattern substantiate the retail investors to be less informed vis-à-vis initial investors, valuers and underwriters, who exit post-listing after profit booking. Investing in the shares of the newly listed ventures post-listing in the secondary market can shield retail investors from the uncertainty losses of being uninformed. The IPO market needs stringent regulations ensuring the verification of the listing valuation, the firm’s credentials and the intent of utilizing IPO proceeds. Healthy development of the IPO market merits reconsidering the listing of ventures with weak fundamentals suspected to withstand the market challenges.

Originality/value

Given the tremendous rise in the new firm venturing into the primary market and the spike in IPOs countering the losses immediately post-opening, the study examines the loss-making and young firms IPOs separately, adding novelty to the study.

Abstract

After a decade of comparative and international education research, evaluation, reflection, and introspection, there still may not be a clear answer to the question: What difference does an Annual Review of Comparative and International Education make? Bereday’s questions regarding the field from the 1960s largely remain unanswered, and what answers there are remain relatively unchanged from the initial review of the field in 2013. In this reflective piece, the editor of the Annual Review of Comparative and International Education provides a retrospective look at what the Annual Review of the field has produced as well as what has not been accomplished over the first 10 years of the Annual Review’s publication. Key points are that (1) comparative and international education continues to be an affiliation-oriented rather than independent, well defined field of study and practice; (2) annual reflection on the field is meaningful even when the field seems resistant to change; and (3) comparative and international education scholars and professionals alike tend to under emphasize reflective scholarship and practice and over emphasize critique or critical commentary; (4) there is promise for the field related to unity, debate, clarification, understanding, and encouragement; (5) the field is persistently under-professionalized; (6) the state of the field is largely unchanged since the 1960s; and (7) the organization and content of the Annual Review itself – much like the field itself – is subject to reflection and change.

Abstract

Purpose

Thermo-magnetic convective flow analysis under the impact of thermal radiation for heat and entropy generation phenomena is an active research field for understanding the efficiency of thermodynamic systems in various engineering sectors. This study aims to examine the characteristics of convective heat transport and entropy generation within an inverted T-shaped porous enclosure saturated with a hybrid nanofluid under the influence of thermal radiation and magnetic field.

Design/methodology/approach

The mathematical model incorporates the Darcy-Forchheimer-Brinkmann model and considers thermal radiation in the energy balance equation. The complete mathematical model has been numerically simulated through the penalty finite element approach at varying values of flow parameters, such as Rayleigh number (Ra), Hartmann number (Ha), Darcy number (Da), radiation parameter (Rd) and porosity value (e). Furthermore, the graphical results for energy variation have been monitored through the energy-flux vector, whereas the entropy generation along with its individual components, namely, entropy generation due to heat transfer, fluid friction and magnetic field, are also presented. Furthermore, the results of the Bejan number for each component are also discussed in detail. Additionally, the concept of ecological coefficient of performance (ECOP) has also been included to analyse the thermal efficiency of the model.

Findings

The graphical analysis of results indicates that higher values of Ra, Da, e and Rd enhance the convective heat transport and entropy generation phenomena more rapidly. However, increasing Ha values have a detrimental effect due to the increasing impact of magnetic forces. Furthermore, the ECOP result suggests that the rising value of Da, e and Rd at smaller Ra show a maximum thermal efficiency of the mathematical model, which further declines as the Ra increases. Conversely, the thermal efficiency of the model improves with increasing Ha value, showing an opposite trend in ECOP.

Practical implications

Such complex porous enclosures have practical applications in engineering and science, including areas like solar power collectors, heat exchangers and electronic equipment. Furthermore, the present study of entropy generation would play a vital role in optimizing system performance, improving energy efficiency and promoting sustainable engineering practices during the natural convection process.

Originality/value

To the best of the authors’ knowledge, this study is the first ever attempted detailed investigation of heat transfer and entropy generation phenomena flow parameter ranges in an inverted T-shaped porous enclosure under a uniform magnetic field and thermal radiation.
