To highlight the pressures that the auditors would face in the era of globalisation and the challenges they should be willing to accept in order to maintain trust and integrity.

A wide range of articles and journals published in international journals as well as local journals has been reviewed. The areas covered include audit fraud, true and fair view interpretation, auditor independence and role of internal auditors. Further, ideas have also been obtained from critical write‐ups in the business magazines on the fall of multinationals.

A wide range of interpretation has been given by various groups of people on their understanding of the phrase “true and fair”. This has created great confusion as to the interpretation of the audit reports. This has been proven by the fall of many multinationals and the audit pioneers, Andersens. This is one of the causes of audit fraud and it is also seen that as the auditors face an enormous challenge as they enter the twenty‐first century, they should be willing to change their attitudes towards their clients. Professionalism should be in the forefront, and an overhaul in the concept of “true and fair” could probably be the solution to harmonisation of the economy.

This paper lacks statistical data on the views of the authors. It is based purely on secondary data.

Provides awareness to the auditors, corporations and general public on the necessity to revamp the existing auditing practices. This can help the auditors not only to be professionals, but also to be seen as professionals.

This paper provides scope for research in this area to identify whether the overhaul concept is acceptable. If yes, what should the new concept be? If no, what is the solution to the existing public outcry?

This paper aims to explore factors influencing the effectiveness of tax audit in Tanzania. The study organized factors into four categories: organizational-related, tax auditors-related, taxpayers-related and regulatory-related factors.

The study used an explanatory approach, whereby data from 225 auditors in 23 tax regions in Tanzania were collected using a mailed questionnaire. The questionnaire had 25 statements representing factors and 5 statements representing the tax audit effectiveness. The collected data were analysed using both descriptive and inferential statistics. In the case of descriptive statistics, the study used frequency, percentage, mean and standard deviation. For the inferential statistics, the study used exploratory factor analysis (EFA) and multiple regression analysis.

The study findings showed that there were five main critical factors for tax audit effectiveness. The first factor, which is the implementation of tax auditors’ recommendations by management, was found under the organizational category. The second factor, which was adequacy of tax audit unit, was found under the tax auditors’ category, while the third factor was taxpayers’ attitude, found under the taxpayers’ category. The fourth and fifth factors, which were availability and application of regulations and standards for tax audit, and leadership and tax policies for tax audit, respectively, were found under the regulatory category.

Despite the contributions of this study, there are some limitations which need to be acknowledged. First, data were collected from tax auditors only. Second, only 25 statements for factors were used. Third, the study has used only primary data. Last, the study has used perceptual measures of tax audit effectiveness. The authors consider that if other approaches were used, they could have reached different conclusions. Therefore, future studies could be conducted in the areas where limitations have been identified.

From a practical perspective, tax authorities may be relying heavily on tax auditors, as well as regulations and policies, for tax audit effectiveness. The study shows that taxpayers, management, as well as tax audit standards, are critical factors too. However, the study also has practical implications for governments, tax authorities, tax auditors as well taxpayers.

This paper extends prior research in the area of tax audit and is the first paper to use four categories of factors to analyse the influence of tax audit effectiveness, taking into consideration both tax authorities and taxpayers. It also used EFA, which helped to generate variables with multiple prior theories (i.e. theoretical triangulation). Hence, new theories were combined with old theories to produce findings which take into consideration the context of the country.

Petroleum hydrocarbons are naturally occurring flammable fossil fuels used as conventional energy sources. It has carcinogenic, mutagenic properties and is considered a hazardous pollutant. Soil contaminated with petroleum hydrocarbons adversely affects the properties of soil. This paper aim to remove pollutants from the environment is an urgent need of the hour to maintain the proper functioning of soil ecosystems.

The ability of micro-organisms to degrade petroleum hydrocarbons makes it possible to use these microorganisms to clean the environment from petroleum pollution. For preparing this review, research papers and review articles related to petroleum hydrocarbons degradation by micro-organisms were collected from journals and various search engines.

Various physical and chemical methods are used for remediation of petroleum hydrocarbons contaminants. However, these methods have several disadvantages. This paper will discuss a novel understanding of petroleum hydrocarbons degradation and how micro-organisms help in petroleum-contaminated soil restoration. Bioremediation is recognized as the most environment-friendly technique for remediation. The research studies demonstrated that bacterial consortium have high biodegradation rate of petroleum hydrocarbons ranging from 83% to 89%.

Proper management of petroleum hydrocarbons pollutants from the environment is necessary because of their toxicity effects on human and environmental health.

This paper discussed novel mechanisms adopted by bacteria for biodegradation of petroleum hydrocarbons, aerobic and anaerobic biodegradation pathways, genes and enzymes involved in petroleum hydrocarbons biodegradation.

The purpose of this study is to propose a framework for the evaluation of the perceived value internal audit functions add to their organisations. The framework is based on service quality measurement principles, specifically SERVPERF, which is applied to internal auditing.

Insights obtained from the literature on internal auditing and service quality disciplines were synthesised to identify and structure value-adding attributes of internal auditing. A thematic analysis of published profiles (by Protiviti) of various organisations’ internal audit functions were analysed and evaluated against those attributes identified in the literature to formulate an evaluation framework based on service quality measurement principles.

The identified value-adding attributes were categorised according to the dimensions of the SERVPERF service quality measurement instrument to formulate a framework for evaluation of the value added by internal audit functions. It was found that the SERVPERF dimensions appear to be relevant to internal auditing. The SERVPERF instrument was therefore adapted to evaluate the value added by internal auditing as a service.

This paper contributes to both the theory and practice of internal auditing by proposing formal dimensions of a value-adding internal audit service which can then serve as a reference point from which to evaluate the value added to an organisation. The framework can serve as a starting point for internal audit functions to develop their service offering and/or form the foundation of stakeholder satisfaction surveys.

The study contributes to the literature by applying service quality principles to internal auditing. A holistic framework that can be used for the evaluation of the value added by internal audit functions based on stakeholder perceptions is proposed. The framework juxtaposes attributes of value-adding internal auditing with recognised service quality performance measures. The notion of value added is investigated to better understand the concept in the context of internal auditing services.

This study aims to demonstrate a modified wire arc additive manufacturing (AM) named non-transferring arc and wire AM (NTA-WAM). Here, the build plate has no electrical arc attachment, and the system’s arc is ignited between tungsten electrode and filler wire.

The effect of various deposition conditions (welding voltage, travel speed and wire feed speed [WFS]) on bead characteristics is studied through response surface methodology (RSM). Under optimum deposition condition, a single-bead and thin-layered part is fabricated and subjected to microstructural, tensile testing and X-ray diffraction study. Moreover, bulk texture analysis has been carried out to illustrate the effect of thermal cycles and tensile-induced deformations on fibre texture evolutions.

RSM illustrates WFS as a crucial deposition parameter that suitably monitors bead width, height, penetration depth, dilution, contact angle and microhardness. The ferritic (acicular and polygonal) and lath bainitic microstructure is transformed into ferrite and pearlitic micrographs with increasing deposition layers. It is attributed to a reduced cooling rate with increased depositions. Mechanical testing exhibits high tensile strength and ductility, which is primarily due to compressive residual stress and lattice strain development. In deposits, ϒ-fibre evolution is more resilient due to the continuous recrystallisation process after each successive deposition. Tensile-induced deformation mostly favours ζ and ε-fibre development due to high strain accumulations.

This modified electrode arrangement in NTA-WAM suitably reduces spatter and bead height deviation. Low penetration depth and dilution denote a reduction in heat input that enhances the cooling rate.

This paper aims to investigate the additive manufacturing (AM) approach of a spatial complex curve feature (SCCF, mapped from two-dimensional nonuniform rational B-splines [2D-NURBS] curve) on a complex surface based on a serial robot using plasma built-up welding, and lays a foundation for plasma AM SCCFs on complex surfaces by combining the NURBS theory with the serial robotic kinematics.

Combining serial robotic kinematics and NURBS theory, a SCCF mapped from a square-like 2D-NURBS curve is prepared on a predefined complex NURBS surface using serial robotic plasma AM. The interpolation points C (ui) on the square-like 2D-NURBS curve are obtained using the equi-chord length interpolation method, and mapped on a predefined NURBS surface to get mapped points S (ui, vj). The homogeneous transformation matrix T = [n o a S (ui, vj)] of the plasma torch is calculated using the mapped points S (ui, vj) and the designated posture [n o a]. Using the inverse kinematics of the serial robot, the joint vector θ of the serial robot can be computed. After that, the AM programs are generated and transferred into the serial robotic controller and carried out by the serial robot of Motoman-UP6. The 2D-NURBS curve (square-like) is considered as AM trajectory planning curve, while its corresponding SCCF mapped from the 2D-NURBS curve as AM trajectory.

Simulation and experiments show that the preparation of SCCF (mapped from 2D-NURBS curve) on complex NURBS surface using robotic plasma AM is feasible and effective.

A SCCF mapped from a 2D-NURBS curve is prepared on a complex NURBS surface using the serial robotic plasma AM for the first time. It provides a theoretical and technical basis for plasma AM to produce SCCFs on complex surfaces. With the increasing demand for surface remanufacturing of complex parts, the serial robotic plasma AM of SCCFs on complex NURBS surfaces has a broad application prospect in aero-engine components, high-speed rail power components, nuclear industry components and complex molds.

The failure of structures and components made of SS304 steel because of corrosion in the presence of saline water environment is still an unsolved issue across the globe. Conventionally, coatings and inhibitors are used to mitigate corrosion. The purpose of this study is to propose a novel method to tackle corrosion by means of micro-patterning on the surface and to explore the relation between surface morphology, corrosion and wetting nature of micro-patterned SS304 Steel.

Groove-shaped micro-patterns were created on SS304 steel surface with varying ridge and channel widths. Wettability studies conducted on flat and micro-patterned steel surfaces using high speed camera. Corrosion tests carried out in saline water using an electrochemical test set-up to quantify the performance of micro-patterned surface over flat surface and scanning electron microscopic analysis to visualize the severity of corrosion on the surfaces of SS304 steel.

Wettability studies showed that the micro-patterned steel surfaces were hydrophobic. Corrosion rates of the micro-patterned steel surfaces were lower by more than an order of magnitude compared to that of the flat steel surface. Scanning electron microscopic analysis revealed that the micro-patterned steel surfaces had less surface damage compared to the flat surface.

The author shows that the remarkable corrosion resistance shown by the micro-patterned steel surfaces is attributed to their hydrophobicity, which reduced the contact between the surfaces and the corrosive liquid media. Results from the investigation indicate that micro-patterning of SS304 steel surfaces is an effective route to decrease corrosion.

This study aims to investigate the relationship between corporate governance (CG) and performance of Real Estate Investment Trust (REITs) in Singapore and Malaysia.

The CG attributes that contribute best toward R-Index scores are tested followed by analysis of whether R-Index scores contribute toward better performance of the REITs when controlled for growth, firm size and leverage. Regression analysis using structured equation modeling (SEM) is instituted.

All attributes in the R-Index except management ownership are significantly correlated to R-Index. Regression analysis using SEM reveals that all the three measures of performance are significant. When controlled for growth and firm size, CG mechanisms reduce the impact of losses. However, highly levered firms could be risky for investors despite strong CG mechanisms.

All S-REITs and M-REIT sampled were grouped as one regardless of the country differences, which may have limited the results and findings. The R-Index used to score the CG practices for Asia is still very new.

Findings of the study will help REIT policymakers to update scorecards frequently. Loss-making REITs must emphasize on specific CG attributes to enhance their overall CG scores to gain market confidence and procure financial assistance through better disclosure.

Due to research scarcity on CG effectiveness associated with performance of Asian REITs after the global financial crisis, this study comes as a timely contribution in understanding the relationship between CG and performance of REITs.

This paper aims to investigate auditors’ pricing of excess cash holdings and the variation in their pricing decisions in light of the precautionary motives of cash holdings and certain firm-specific conditions and during periods of crisis.

The authors conduct the two-stage-least-squares multivariate analysis using a sample of publicly listed non-financial US firms for the period 2003 to 2021 (42,413 firm-year observations).

The findings show a significant positive relationship between excess cash and audit fee. Next, the authors find that audit pricing of excess cash is significantly higher for firms with lower financial constraints. However, the authors do not find evidence to suggest that auditors price excess cash significantly higher for firms with lower hedging needs. In additional analysis, the authors find evidence to suggest that auditors charge significantly less for excess cash in firms that report financial loss and firms operating in industries with high litigation risk. The additional analysis also reveals excess cash is not positively and significantly priced by auditors as a result of the global financial crisis and Covid-19 pandemic.

Most researchers have analyzed excess cash holding from the perspective of managers, i.e. agency conflict or managerial prudence, while somewhat neglecting auditors’ perception of the embedded risk of excess cash holdings. The authors provide new insights on auditors’ perspective of excess cash holding and identify certain factors/situation/conditions that cause variation in the audit fee premium. The findings offer useful insights for managers and shareholders who are interested in assessing the effects of excess cash holdings policies on the audit fee premium.

To examine the impact of corporate governance on Cost of Capital (COC) and financial distress in the ASEAN countries.

We compiled a list of the 50 largest publicly listed firms by market capitalization in each of the following five East Asian countries, namely Malaysia, Singapore, Thailand, the Philippines, and Indonesia. Furthermore, we then divided the five countries into two distinctive categories – (i) Malaysia and Singapore (Common Law/strong legal protection countries) and (ii) Thailand, the Philippines, and Indonesia (Civil Law/weak legal protection countries). The annual data is collected for the time period ranging from 2006 to 2015, allowing a total observation of 1,317 firm years.

Overall, the paper supports the findings of many researchers that Board independence, promulgating good corporate governance, leads to better access to capital at lower cost, thus providing growth opportunities for ASEAN region. Taking lead from Simpson and Gleason (1999) and similar, we emphasize that during financial distress CEO duality will strengthen control systems and reduce internal discord in ASEAN firms.

The paper is one of the niche studies that has incorporated the difference between civil and common law rule in the study of corporate governance and its impact on financial measures of firms' in the ASEAN countries.
