Abstract

The second of a two‐part article (Part I published in IJPSM , Vol. 5 No.1) which continues the historical overview from 1949 when the new democratic government instigated administrative reforms based on initiatives from foreign research. In the period after the Second World War attempts at reform were hindered by increased number of Civil Servants and economic problems, particularly inflation and a fall in the standard of living. Traces the difficulties which emerged between the bureaucracy and successive governments as a direct result of their failure to appreciate the role of the bureaucracy. The 1960 revolution led to the establishment of three bodies with specific tasks to change the structure of the economic and administrative systems and to implement five‐year plans, but which met with limited success. Discusses the ensuing excessive review and evaluation in every sphere of state activity which has continued to date.

Abstract

Purpose

Because many cutting fluids contain hazardous chemical constituents, industries and researchers are looking for alternative methods to reduce the consumption of cutting fluids in machining operations due to growing awareness of ecological and health issues, government strict environmental regulations and economic pressures. Therefore, the purpose of this study is to raise awareness of the minimum quantity lubrication (MQL) technique as a potential substitute for environmental restricted wet (flooded) machining situations.

Design/methodology/approach

The methodology adopted for conducting a review in this study includes four sections: establishment of MQL technique and review of MQL machining performance comparison with dry and wet (flooded) environments; analysis of the past literature to examine MQL turning performance under mono nanofluids (M-NF); MQL turning performance evaluation under hybrid nanofluids (H-NF); and MQL milling, drilling and grinding performance assessment under M-NF and H-NF.

Findings

From the extensive review, it has been found that MQL results in lower cutting zone temperature, reduction in cutting forces, enhanced tool life and better machined surface quality compared to dry and wet cutting conditions. Also, MQL under H-NF discloses notably improved tribo-performance due to the synergistic effect caused by the physical encapsulation of spherical nanoparticles between the nanosheets of lamellar structured nanoparticles when compared with M-NF. The findings of this study recommend that MQL with nanofluids can replace dry and flood lubrication conditions for superior machining performance.

Practical implications

Machining under the MQL regime provides a dry, clean, healthy and pollution-free working area, thereby resulting the machining of materials green and environmentally friendly.

Originality/value

This paper describes the suitability of MQL for different machining operations using M-NF and H-NF.

This paper aims to study inhibitory effect of 4-aminothiophenol on the corrosion of mild steel (MS) in 0.5 M HCl.

Abstract

Purpose

This paper aims to study inhibitory effect of 4-aminothiophenol on the corrosion of mild steel (MS) in 0.5 M HCl.

Design/methodology/approach

In this study, electrochemical experiments, quantum chemical calculations, potentiodynamic measurements, linear polarization resistance and scanning electron microscopy were used.

Findings

The experimental results suggest that this compound is efficient corrosion inhibitor and the inhibition efficiencies increase with increasing their (from 0.5 to 10.0 mM.) concentrations. This reveals that inhibitive actions of inhibitors were mainly due to adsorption on mild steel surface. The adsorption of these inhibitors was found to obey Langmuir adsorption model. The computed quantum chemical features show good correlation with empirical inhibition efficiencies.

Originality/value

The 4-aminothiophenol is suitable inhibitor for application in closed-circuit systems against corrosion. The study is original and has great impact in industrial area. The obtained theoretical results have been adapted with the experimental data.

Abstract

Purpose

In this paper, two promising corrosion inhibitors based on natural and eco-friendly materials such as peanut fatty acids (PFA) were prepared and challenged with a common efficient commercial inhibitor. Two amino derivatives based on aliphatic and aromatic compounds such as 2-amino-2-methyl-1-propanol (AMP) and 2-amino-2-phenyl-1-propanol (APP), respectively, were used and reacted with PFA under controlled conditions to produce the corrosion inhibitors. The prepared inhibitors, namely, PFA-AMP (inhІ) and PFA-APP (inhІІ), were confirmed and characterized by Fourier transfer infrared spectroscopy, acid value determination and viscosity measurements.

Design/methodology/approach

First, different coating formulations free from any inhibitors were prepared and irradiated under different doses of electron beam source to select the best dose. Several concentrations of synthesized anticorrosion materials were then added to coating formulations to estimate them as anticorrosion materials for mild steel panels. Then, all formulations were coated and polymerized at a dose of 10 kGy. The corrosion tests, weight loss and water uptake were studied for all films after immersion in 3.5% sodium chloride. Moreover, the chemical and physico-mechanical properties were determined for all films.

Findings

The results exhibited that the different concentrations of two inhibitors did not show any significant change on the different properties of all films, and the best concentration, which gives the better protection for steel panels, was to be 1.0 g for two inhibitors.

Originality/value

It was found that the protection efficiency of the inhІ is better and higher than that of the inhІІ and also of the commercial inhibitor with the following order: inhІ > commercial inhibitor > inhІІ.

Abstract

Cu(II) complexes with some hydroxy azo compounds derived from thiazole and benzothiazole have been synthesized. The structures of the complexes are inferred from data of elemental analysis, electronic, IR and H1 NMR spectra. It is found that the Cu(II) coordinated to ligands through the nitrogen atom of azo group and hetero ring. This coordination lead to lower the energy of CT transition of ligands. The effect of molecular structure of the ligands and nature of the metal ion on complex formation are also examined. The free energy and stability constant of complexes formed in solution have been determined spectrophotometrically. Thiazole azo dyes were found to behave as an inhibitor with respect to the corrosion of copper in acidic solutions.

Abstract

Purpose

To contribute to the design of the energy service companies (ESCOs)' environment in the Mediterranean countries, mainly focusing on the constraints this company's environment face and the actions that can fulfil its needs and aims, taking also into consideration the opportunities and threats emerging from the energy liberalization and climate change.

Design/methodology/approach

The methodology that was followed (based in a large part on the context of two projects targeted to the Mediterranean region and funded by the European Commission) incorporated four steps, the desk analysis for energy efficiency potential in the Mediterranean, the data collection, the assessment of the constraints and the final assessment of the ESCOs' environment.

Findings

Provides information regarding the current status of ESCOs' development, in the dimensions of the ESCOs' environment (political/legal, economical/financial, social/cultural and technological), both in the European Union (EU) (Cyprus, France, Greece, Italy, Malta and Spain) and non‐EU (Algeria, Egypt, Israel, Jordan, Lebanon, Morocco, Syria, Tunisia and Turkey) Mediterranean countries.

Originality/value

There are no papers investigating the activation environment of ESCOs in a coherent and integrated way in the Mediterranean. This paper provides to decision makers a supportive framework for policy design and formulation of policy priorities for ESCOs development in the region.

Abstract

Purpose

This study aims to establish a comprehensive understanding of the intricacies of how individuals engage with deepfakes, focusing on limiting adverse effects and capitalizing on their benefits.

Design/methodology/approach

This study conducted a meta-synthesis of qualitative studies on deepfakes, incorporating study-specific analysis followed by a cross-study synthesis.

Findings

Based on the meta-synthesis, the study developed an integrated conceptual framework based on the perspectives from the social shaping of technology theory embedding deepfake-related assertions, motivations, the subtleties of digital platforms, and deepfake-related repercussions.

Research limitations/implications

The study offers crucial insights into the evolving nature of deepfakes as a socio-technical phenomenon and the significance of platform dynamics in deepfake production. It enables researchers to comprehend the cascading effects of deepfakes and positions them to evaluate deepfake-related risks and associated mitigation mechanisms.

Practical implications

The framework that emerges from the study illustrates the influence of platforms on the evolution of deepfakes and assists platform stakeholders in introducing effective platform governance structures to combat the relentless proliferation of deepfakes and their consequences, as well as providing guidance for governments and policymakers to collaborate with platform leaders to set guardrails for deepfake engagement.

Originality/value

Deepfakes have been extensively contested for both their beneficial and negative applications and have been accused of heralding an imminent epistemic threat that has been downplayed by some quarters. This diversity of viewpoints necessitates a comprehensive understanding of the phenomenon. In responding to this call, this is one of the first to establish a comprehensive, theoretically informed perspective on how individuals produce, process, and engage with deepfakes through a meta-synthesis of qualitative literature on deepfakes.

Abstract

Purpose

The purpose of this paper was to explore the antioxidant and antimicrobial properties of locally available herbs, namely, Bacopa monnieri in enhancing the shelf life of chicken nuggets.

Design/methodology/approach

Meat products are highly vulnerable to spoilage due to their excessive fats and protein content. Therefore, chicken nuggets incorporated with 1, 2 and 3 per cent Bacopa monnieri extracts and control chicken nuggets, were studied to explore the potency of this locally available herb on oxidative stability and storage quality of chicken nuggets on the 0,7th,14th and the 21st day at the refrigerated storage (4 ± 1°C).

Findings

Extracts of Bacopa monnieri were prepared and optimally incorporated in the chicken nuggets. Chicken nuggets prepared with 2 per cent of Bacopa monnieri were adjudged as the best among all based on sensory attributes. Extracts of Bacopa monnieri-incorporated nuggets were safe for consumption until 21 days of refrigerated storage (4 ± 1°C), based upon the power of hydrogen (pH), free fatty acid (FFA), thiobarbituric acid reactive substances (TBARS), microbiological profile and sensory evaluation of the chicken nuggets.

Practical implications

Two per cent of Bacopa monnieri extracts’ incorporation in the chicken nuggets successfully improved the oxidative stability and storage quality of chicken nuggets and, therefore, can be commercially exploited.

Social implications

The Bacopa monnieri herb is commonly available in the Jammu region of Jammu and Kashmir state in the Indian Republic; hence, it can be used in its extract form in meat products, to make the products function with enhanced shelf life.

Originality/value

The addition of 2 per cent extracts of Bacopa monnieri in the chicken nuggets successfully improved the oxidative stability and its storage quality during the refrigerated (4 ± 1°C) storage. Therefore, it can be commercially exploited to improve the storage quality for longer duration of the meat food without adversely affecting the sensory quality of the products.

Abstract

Purpose

Effective leaders have emerged as the cornerstone of project success. The major purpose of this paper is to propose a framework to categorize and prioritize leadership competencies for project managers in megaprojects.

Design/methodology/approach

In the first stage, this study utilizes PMBOK 6th Edition, IPMA ICB 4.0 frameworks to develop a hierarchy-based four clusters of leadership competencies. In the second stage, a Fuzzy-AHP (Analytic Hierarchy Process) approach was employed to prioritize the leadership competencies for an organization dealing in megaprojects. Finally, using ordinal priority approach (OPA), the results of Fuzzy-AHP method are validated.

Findings

Based on PMBOK, IPMA and literature, the proposed framework deduced twenty-four leadership competencies and grouped them in four clusters. The Fuzzy-AHP results indicate that among clusters, people competencies cluster is ranked most important, followed by perspective, practice, and innovation competencies. Considering the sub-categories and global weights, culture/values, governance, interpersonal skills, and development and growth emerged as the most important leadership competencies. The results from OPA corroborate the findings of Fuzzy-AHP method.

Practical implications

Megaprojects are characterized by massive investments and extensive economic and social impact. The proposed framework would be an important aid for policymakers to develop suitable strategies and programs to inculcate leadership competencies that would lead to successful project managers and improved project performance.

Originality/value

The need for this research stems from the need to integrate popular project management frameworks in leadership competencies development in project based organizations. The proposed integrated framework, based on PMBOK 6th Edition and IPMA ICB 4.0 competency frameworks, is an original contribution to understand and prioritize leadership competencies for megaproject success.
