The study seeks to analyze concepts of “career grades” and “job grading,” to highlight their importance and objectives for the efficiency of administrative systems. In addition, it identifies the international standards that can be used to draw grading systems. It explores the most important types of grade structures. It also clarifies grading systems in the Egyptian administrative system. It indicates some methods that can be considered a form of career progression.

The study employs descriptive, analytical, as well as, legal approaches; it analyzes the information given in the study in terms of relevant legal texts.

The study identifies precise definitions of both career grades and job grading, referring to these concepts in the Egyptian administrative system. It also suggests that there is no ideal hierarchy to be applied in all administrative systems. Therefore, the study provides some criteria that help to form the appropriate grade structure for each system.

The study analyses some literature on “job grading,” its objectives, its criteria and its main types, presenting an integrated framework that can be used to develop career-structure systems. Finally, the study identifies some methods that can be considered as a means of grading.

This study, using systematic literature review (SLR) aims to highlight and summarise current studies on the factors influencing customers’ Islamic home financing (IHF) selection and Islamic banking product preference, which has gained popularity within the banking sector over the past three decades. The SLR could map evolution and research fields, recommend a particular categorisation and determine primary issues to demonstrate current trends, future research directions and theoretical development.

The SLR was performed with a four-step reporting standard for the systematic evidence syntheses review method (research question formulation, systematic searching, quality assessment and data extraction) using 33 screened articles between 2008 and 2020 from two primary databases (Scopus and Web of Science) and one supporting database (Google Scholar).

The resulting factors could be categorised into four primary themes: consumer behaviour, consumer attributes, bank attributes and bank attributes (Islamic). The themes were subsequently divided into 16 sub-themes. Notably, all the factors proved essential for consumers’ evolving preferences and product competitiveness in the market.

This study encountered two limitations based on database selection and research period.

This SLR aimed to offer useful insights into the factors that should be prioritised by financial institutions for marketing approaches by investigating consumer behaviours.

This study pioneered an SLR on the study area for useful insights into the current research limitations and recommendations on future study directions. Specifically, the study method facilitated critical discussions and comparisons to past research outcomes and objectivity with triangulation from distinct perspectives.

Gold investment is one of the essential long-term investments for many to diversify their investment portfolios. Muslims are continuously looking for halal products and services in any aspect of life and one of them is Shari’ah gold investments (SGI). However, evidence pertinent to Muslims’ behaviour towards Shari’ah gold is somewhat inconclusive and for that, a new empirical investigation is needed to reduce the gap, at best. Hence, the purpose of this study is to study factors determining SGI behaviour in Penang, Malaysia.

By using the Islamic theory of consumer behaviour (ITCB), this study examines the determinants of the SGI behaviour. The questionnaire survey was distributed and the data gathered was analysed using partial least square structural equation modeling.

All hypothesised hypotheses were instrumental in explaining the factors determining SGI behaviour in the context of Penang, Malaysia.

This study has at least two limitations, namely, confined generalisations of the variables used and the limited context of the research conducted.

This study sheds light on the determinants influencing SGI behaviour, at best.

This study is original in terms of its final output that enlightens the significant effects of iman, Islamic altruism, maqasid consumer index on the behaviour of investors on Shari’ah gold within the ITCB’s context along with integrated religious satisfaction.

This paper aims to examine the determinants that influence acceptance towards e-wallet apps by extending the technology acceptance model (TAM) among (asnaf), a term used for charity or gift receivers from alms tax distribution institutions also known as donee.

The review of literature and structural equation modelling approach using judgemental sampling on extended TAM and determinants of e-wallet apps’ acceptance related to asnaf (donee) were conducted in a bid to contribute to the factors that are instrumental in determining acceptance of e-wallet services among asnaf.

The findings indicate that the e-wallet app’s service acceptance is determined not only by perceived usefulness, consumer maqasid index and consumer innovativeness but also by subjective norms. On the contrary, consumer maqasid index and perceived ease of use do not lend themselves to be the factor of asnafs’ e-wallet acceptance. The authors extend the TAM model to determine the factors that may be influential in predicting the e-wallet app acceptance by asnaf.

In assessing future outcomes when different sampling techniques are opted for and geographic coverage is expanded, this study should be considered in terms of the limited scope.

This study is intended to serve as a reference for making a significant contribution related to user acceptance factors related to alms tax-based e-wallet apps in asnafs’ context in Malaysia in terms of both theory and practice.

TAM is extended in the context of e-wallet app acceptance among asnafs’. A variable, namely, consumer innovativeness, is tested using the extended TAM model. To the best of the authors’ knowledge, consumer innovativeness in the context of asnafs’ acceptance of e-wallet apps is yet to be tested. Therefore, this paper will be a useful reference for policymakers, technologists, academicians and future researchers.

The purpose of this paper is to draw a map of the general features of epistemological and critical concerns in contemporary Islamic philosophy. This study will not be confined to the domain of academic philosophy or to those who are professionals in the field of philosophy.

The paper adopted the critical rational approach in dealing with contemporary Islamic philosophy in the Arab world. The scope will include scholars from different fields of epistemology who tried to present a “vision” of the attitude that should be adopted in facing the challenges of the age and the problems of the nation on the epistemological level or the political, economic and social levels.

There is a need for a philosophy of action and progress rather than a philosophy that is based on abstract ideas and theories and of words/rhetoric. The ethics required to accomplish this ought to identify the attributes of the citizen who can reach self-actualization through legitimate means based on a progress agenda with theoretical and philosophical foundations.

Because a critical rational approach can be dealt with from different perspectives, this paper will adopt the classification of the principal intellectual trends: the reformist, secular and liberal.

This paper covers a long time span to determine whether the philosophical projects have been effective.

This paper, which criticizes the philosophic projects that are theoretically unsound and that do not address real social problems (like poverty), argues the need for a philosophy of progress and action. This will lead to devising an agenda that addresses the challenges the society is facing and to finding alternative and creative solutions resulting in development.

Locally derived foods from the lens of restaurant settings play an important source of tourist attraction. Surprisingly, research into this sector is quite scarce. The aim of the paper is to develop and empirically examine a conceptual framework on tourist’s preferences in selecting local foods. The framework includes tourists’ satisfaction, quality of food, tourist’s perception, purchase intention and purchase behavior among tourist’s selection for local foods.

The research is designed as quantitative in nature. A sum of 280 usable questionnaires was used from 300 distributed instruments by using convenient sampling techniques.

The results show that the relationship of tourist satisfaction and behavior is mediated by purchase intention, whereas tourist’s satisfaction and perception have a positive and significant impact on the intention of purchasing local foods. There is also a significant relationship between tourist’s satisfaction and perceived quality toward the tourist’s perception of local foods. Moreover, a significant relationship exists between tourist’s intentions and tourist’s purchase behavior.

The study derived the purchase behavior dimensions of local foods by the tourists through literature and verified the conceptual model through empirical testing. Based on these findings, managers of local food restaurants require maximizing the purchase behavior of the visitors by considering satisfaction and perceived quality. In summation, they also should consider perception and behavioral intention of tourists. The limitation of this research relates to the sample, where data were collected from the major city of a tourist-friendly country. Future research could investigate the perceived value and gender variance as moderating variables in and between purchase intention and purchase behavior.

Managers and policymakers may use the outcome of this research as a guideline to understand the depth of tourist’s behavior. By identifying the antecedents of the behavioral factors may assist the managers to strengthen the restaurant’s competitive position within the industry. Finally, policymakers may use the research to assess tourists’ perceptions of local foods acceptability in promoting the nation’s culture to other parts of the world.

This work adds to tourism behavior research by exploring the effect of satisfaction, perceived quality, perception and intention on behaviors associated with local foods purchase behavior. In particular, the study highlights the relationships between tourist’s perception, perceived quality of local foods and satisfaction of local foods to measure tourist’s behavior through purchase intention for local foods from the perspective of restaurant settings, which have received less research attention.

Corrosion is a major concern for many industries that use metals as structural or functional materials, and the use of corrosion inhibitors is a widely accepted strategy to protect metals from deterioration in corrosive environments. Moreover, the toxic nature, non-biodegradability and price of most conventional corrosion inhibitors have encouraged the application of greener and more sustainable options, with natural and synthetic drugs being major actors. Hence, this paper aims to stress the capability of natural and synthetic drugs as manageable and sustainable, environmentally friendly solutions to the problem of metal corrosion.

In this review, the recent developments in the use of natural and synthetic drugs as corrosion inhibitors are explored in detail to highlight the key advancements and drawbacks towards the advantageous utilization of drugs as corrosion inhibitors.

Corrosion is a critical issue in numerous modern applications, and conventional strategies of corrosion inhibition include the use of toxic and environmentally harmful chemicals. As greener alternatives, natural compounds like plant extracts, essential oils and biopolymers, as well as synthetic drugs, are highlighted in this review. In addition, the advantages and disadvantages of these compounds, as well as their effectiveness in preventing corrosion, are discussed in the review.

This survey stresses on the most recent abilities of natural and synthetic drugs as viable and sustainable, environmentally friendly solutions to the problem of metal corrosion, thus expanding the general knowledge of green corrosion inhibitors.

The aim of this paper is to appraise the inhibiting potential of hydroxypropyl methylcellulose (HPMC) on the corrosion of mild steel and aluminium in sulphuric and hydrochloric acid solutions.

The effects of two different corrodents on the dissolution of mild steel and aluminium were examined. Corrosion rates were determined using the weight loss technique. Inhibition efficiency was estimated by comparing the corrosion rates in absence and presence of the additive. The kinetics and mechanism of HPMC adsorption were investigated by impedance study while the anodic and cathodic partial reactions were studied by polarization measurements.

The results reveal that corrosion rate of mild steel and aluminium decreased with addition of HPMC. The corrosion rate and inhibition efficiency were found to depend on the concentration of the inhibitor. The polarization data indicated that the inhibitor was of mixed-type, with predominant effect on the cathodic partial reaction. electrochemical impedance spectroscopy confirms that corrosion inhibition was by adsorption on the metal surface following Freundlich adsorption isotherm via physisorption mechanism.

Hydroxypropyl methylcellulose has been studied for the first time as an inhibitor of mild steel and aluminium corrosion and the results suggest that the inhibitor could find practical applications in corrosion control in HCl and H₂SO₄ acid media. The findings are particularly useful, considering the fact that HPMC is a good film former and viscosity enhancer which could also be used in paint formulation.

This paper aims to study the corrosion inhibition of Methyl 2-(benzamido)-2-(4-phenyl-1H-1,2,3-triazol-1-yl) acetate (MBPTA) and Methyl 2-(benzamido)-2-(4-p-tolyl-1H-1,2,3-triazol-1-yl) acetate (MBTTA) in 1 M H2SO4 solution at 25 °C.

The authors have used weight loss measurements, electrochemical impedance spectroscopy (EIS), potentiodynamic polarization, FT-IR, quantum chemical calculations and scanning electron microscopy (SEM) techniques.

The polarization measurements indicate that both compounds are mixed type inhibitors, and that MBTTA is more effective than MBPTA. The effect of temperature on the corrosion behavior using optimal concentration of MBTTA and MBPTA was studied in the temperature range 298-328 K. SEM was used to examine the morphology of the metal surface. Thermodynamic parameters were calculated and discussed. Monte Carlo simulations were applied to lookup for the most stalls configuration and adsorption energy for the interaction of inhibitors on Fe (1 1 1) interface. The difference in inhibition efficiencies between the two organic inhibitors can be clearly explained in terms of frontier molecular orbital theory.

The authors report on the comparative inhibiting effect of two new 1,4-disubstituted 1,2,3-triazoles, namely Methyl 2-(benzamido)-2-(4-phenyl-1H-1,2,3-triazol-1-yl) acetate (MBPTA) and Methyl 2-(benzamido)-2-(4-p-tolyl-1H-1, 2, 3-triazol-1-yl) acetate (MBTTA) on mild steel corrosion in 1 M H₂SO₄ solution.

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

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

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.

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.
