Abstract

Purpose

Renal failure is an end-stage consequence after persistent hyperglycemia during diabetic nephropathy (DN), and the etiology of DN has been linked to oxidative stress. The purpose of this research was to determine the beneficial synergistic effects of S-Allyl Cysteine (SAC) and Taurine (TAU) on oxidative damage in the kidneys of type 2 diabetic rats induced by hyperglycemia.

Design/methodology/approach

Experimental diabetes was developed by administering intraperitoneal single dose of streptozotocin (STZ; 65 mg/kg) with nicotinamide (NA; 230 mg/kg) in adult rats. Diabetic and control rats were treated with SAC (150 mg/kg), TAU (200 mg/kg) or SAC and TAU combination (75 + 100 mg/kg) for four weeks. The estimation of body weight, fasting blood glucose (FBG), oral glucose tolerance test (OGTT), oxidative stress markers along with kidney histopathology was done to investigate the antidiabetic potential of SAC/TAU in the NA/STZ diabetic group.

Findings

The following results were obtained for the therapeutic efficacy of SAC/TAU: decrease in blood glucose level, decreased level of thiobarbituric acid reactive substances (TBARS) and increased levels of GSH, glutathione-s-transferase (GST) and catalase (CAT). SAC/TAU significantly modulated diabetes-induced histological changes in the kidney of rats.

Originality/value

SAC/TAU combination therapy modulated the oxidative stress markers in the kidney in diabetic rat model and also prevented oxidative damage as observed through histopathological findings.

Abstract

Purpose

Taurine (2-aminoethane sulfonic acid; C2H7NO3S) is a nonprotein sulfur-containing β-amino acid present in nearly all mammalian tissues and the most ubiquitous free endogenous biomolecule in human cells. Taurine is commonly known as a conditionally essential amino acid because taurine is one of the few amino acids that are not incorporated in protein synthesis. The purpose of this study is to review the existing articles related to taurine and to give an account how useful is taurine to the different body systems. In this thorough overview, taurine is covered in terms of its essentiality, sources, advantages for neonates and the elderly, the effects of taurine deficiency, and the safety and toxicity of taurine supplements.

Design/methodology/approach

This is a narrative review into the subject matter. Published articles were searched on different portals like PubMed, EMBASE, Scopus, Google Scholar, PubChem etc. The authors also evaluated the availability of taurine in commercially available energy drinks.

Findings

This comprehensive review, presents the potential clinical benefits and functional properties of taurine as a conditionally essential amino acid. Energy drinks containing taurine (and their concentration) are also reported in this review.

Originality/value

This is the first data that the authors are aware of that shows taurine content in a variety of energy drinks on the market.

Abstract

The COVID-19 pandemic, which globally affected all the countries of the world both economically and socially, has become one of the biggest crises after the 1929 world economic depression. During this period, not only people's health but also the economic health of countries was affected. In this process, people have created intense connection traffic on the internet to meet their needs, and this has accelerated the digitalization processes of businesses. Thus, the concept of digital transformation began to be widely used. Today, digital transformation processes have become an external environmental variable that covers all sectors, not businesses in a single sector. This situation has revealed the necessity of creating new business/management strategies that increase customer value for business managers. Digital transformation has shown itself in all business functions. In other words, the demands and priorities of each function and its managers have also changed. Therefore, business and department managers are required that they perceive digital transformation processes correctly and integrate their businesses/departments into this process with the right business/management strategies, without conflicting with the digital transformation processes. In this study, various ideas and evaluations put forward about sustainable business/management strategies that can be applied against the current and future importance of the digitalization/digital transformation process and its possible effects on businesses are included.

Abstract

Purpose

The purpose of this paper is to explore the longitudinal influence of gender, age, education level, organizational tenure and emotional intelligence on three dimensions of knowledge hiding over time.

Design/methodology/approach

A longitudinal study using two-wave data sets of 390 employees in Chinese enterprises was conducted to build fixed, continuous and interacting models for investigating the effects of individual differences on the processes of knowledge hiding over time.

Findings

This research uncovered the changing relationships of individual differences on knowledge-hiding behaviors over time, such that age correlates with rationalized hiding in the interacting model, indicating younger employees are less likely to choose rationalized hiding when facing situation changes; and education level, organizational tenure and emotional intelligence moderate knowledge hiding over time, implying individuals with better education, longer tenure and higher emotional intelligence tend to exhibit more rationalized hiding behaviors rather than evasive hiding and playing dumb behaviors at Time 2.

Originality/value

One of the novel contributions of this study is that it tests the longitudinal effect of individual differences on knowledge hiding, providing a vertical perspective, and thereby contributing to the body of knowledge in knowledge management. The study also constructs fixed, continuous and interacting models to measure the covering longitudinal influences, thus making the research original.

Abstract

Purpose

Current research addresses the issue of brand loyalty while identifying its potential predictors. The research also examines the direct impact of brand credibility on brand loyalty and attitude toward brand and the direct impact of attitude toward brand and on brand loyalty respectively. Moreover, this research examines the mediating effect of attitude toward brand for the relationship of brand credibility and brand loyalty.

Design/methodology/approach

This is a cross-sectional research. Data is collected with the help of structured questionnaire. Simple random sampling technique is used for gathering the data from 220 Samsung users from Lahore, Pakistan.

Findings

Results indicate that brand credibility has a positive influence on attitude toward brand and brand loyalty respectively. Attitude toward brand partially intervenes the relation of brand credibility and brand loyalty.

Research limitations/implications

There are some limitations of the current research. It includes only the customers of Samsung mobile. Data is collected from the customers of Lahore, Pakistan, only. This research can also be conducted among the customers of OPPO, Vivo and Apple and compare the results of current research with the results of OPPO, Vivo and Apple, which will provide the useful insights. This kind of research will also be conducted among the customers of other kinds of products like FMCGs, luxury items and even on the organizations of industrial products for generalizability. In future, customers of other cities of Pakistan like Karachi, Multan and Faisalabad may also be included for generalization.

Practical implications

This research provides a practical framework for the marketing department of Samsung mobiles and explains how brand credibility shape the brand loyalty through the path of attitude toward Samsung mobiles. So, Samsung mobiles can maintain current policies regarding brand credibility and attitude toward brand for attaining the better level of brand loyalty. Longitudinal research studies on these variables will also be helpful for the marketing department of Samsung for checking the level of propose relationships periodically and comparing it with previous results which will provide the true picture about propose relationships. If the value of propose relationships increases or remains at same level, then Samsung can maintain the current policies about these variables and if the value of these variables decreases, the Samsung will improve the current policies about these variables.

Originality/value

This research contributed in theory of reasoned action by proposing the brand credibility, attitude toward brand and brand loyalty in single model. Before this, these relations were explained separately. This research adds to the body of literature by checking the mediating effect of attitude toward brand for the relationship of brand credibility and brand loyalty.

Abstract

Purpose

Several graphs, streamlines, isotherms and 3D plots are illustrated to enlighten the noteworthy fallouts of the investigation. Embedding flow factors for velocity, induced magnetic field and temperature have been determined using parametric analysis.

Design/methodology/approach

Ternary hybrid nanofluids has outstanding hydrothermal performance compared to classical mono nanofluids and hybrid nanofluids owing to the presence of triple tiny metallic particles. Ternary hybrid nanofluids are considered as most promising candidates in solar energy, heat exchangers, electronics cooling, automotive cooling, nuclear reactors, automobile, aerospace, biomedical devices, food processing etc. In this work, a ternary hybrid nanofluid flow that contains metallic nanoparticles over a wedge under the prevalence of solar radiating heat, induced magnetic field and the shape factor of nanoparticles is considered. A ternary hybrid nanofluid is synthesized by dispersing iron oxide (Fe3O4), silver (Ag) and magnesium oxide (MgO) nanoparticles in a water (H2O) base fluid. By employing similarity transformations, we can convert the governing equations into ordinary differential equations and then solve numerically by using the Runge–Kutta–Fehlberg approach.

Findings

There is no fund for the research work.

Social implications

This kind of study may be used to improve the performance of solar collectors, solar energy and solar cells.

Originality/value

This investigation unfolds the hydrothermal changes of radiative water-based Fe3O4-Ag-MgO-H2O ternary hybrid nanofluidic transport past a static and moving wedge in the presence of solar radiating heating and induced magnetic fields. The shape factor of nanoparticles has been considered in this study.

Abstract

Purpose

Identify some of the most relevant factors that trigger a private school's workforce to foster a sustainable competitive advantage by reinforcing the intrinsic job satisfaction and the levels of teacher self-efficacy, engagement and job performance.

Design/methodology/approach

Surveys were applied to private school teachers to assess their perception concerning the studied variables, data were tested at a confirmatory level using the partial least squares path modelling (PLS-PM).

Findings

Teachers with a high sense of self-efficacy and possessing elevated intrinsic satisfaction tend to be highly productive and results-oriented. Intrinsic job satisfaction is a key factor that influences more than extrinsic job satisfaction in the previously mentioned relationship.

Research limitations/implications

Although the obtained results are constrained and apply to the Mexican context, we suggest that virtual limitation can be overcome by extending the study due to the proposed construct that can be applied in other regions or organizations.

Practical implications

Principals will need to develop mainly the intrinsic job satisfaction in the teaching staff, to improve the job and organizational performance. This should be accompanied, secondly, by factors that encourage extrinsic satisfaction such as fair pay or recognition.

Originality/value

Open up an alternative explanation, based on the evidence of this study, to the theory of social exchange, since the factor that most influences teacher’s citizenship behaviours is not extrinsic but intrinsic satisfaction. That is, it is not what the employee receives from the institution, but what the employee does or gives to the institution the source of satisfaction that will encourage greater job performance.

Abstract

Purpose

The purpose of this study is to present and test a conceptual framework that describes the Islamic religiosity parameters of riba, zakat and mafsadah and their influence on the adoption of firms’ corporate social responsibility (CSR) practices.

Design/methodology/approach

The study applied structural equation modelling to empirically test the proposed model on a sample of 109 Pakistan Stock Exchange (PSX) listed firms.

Findings

The study finds that the Islamic religiosity parameters of riba and mafsadah have a positive influence on the adoption of CSR practices, thus confirming the two study hypotheses. However, the authors did not find any significant influence of the zakat parameter on the adoption of firms’ CSR practices.

Research limitations/implications

This study is limited to the Islamic religious concept and only surveyed one stakeholder group, i.e. firms’ managers in the Pakistani context. The authors recommend that future studies should look beyond a single religion with the inclusion of multiple stakeholders in a cross-country setting.

Practical implications

The findings possess important policy implication for regulators, stakeholders and practitioners, as the authors demonstrate that different parameters of religiosity are related to CSR practices and these parameters can be used as a substitute for and complement legal institutions in promoting and developing CSR practices.

Social implications

The stakeholders’ particular investors and other market participants should be aware of the degree of religiousness and the CSR nexus, as surveyed manger responses in PSX listed firms indicate that better religious firms seem to place more emphasis on social responsibility obligations.

Originality/value

This study is among few studies that propose a comprehensive conceptual Islamic religiosity framework to evaluate the influence of a firm’s Islamic religiosity on CSR best practices. It differs from the past studies that were either on Islamic financial institutes or examined the religious influence on a firm’s economic behaviours.

Abstract

Purpose

The purpose of this paper is to analyse the factors which influence value co-creation intention through customer engagement during the COVID-19 pandemic. This paper studies the online modest fashion small- and medium-sized enterprises (SMEs) in Egypt as a Muslim country.

Design/methodology/approach

This paper is based on the social cognitive theory (SCT) and the literature to develop a theoretical framework of the factors influencing customers’ value co-creation intention on social media. The framework is then tested quantitatively through structural equation modelling based on partial least squares method (SEM-PLS) approach using the SmartPLS software.

Findings

The empirical analysis supported the SCT through the following conclusions: first, regarding the subject factors, self-efficacy has a positive significant effect on all dimensions of customer engagement and outcome expectation has a positive significant effect on cognitive customer engagement. Concerning the environmental factors, community experience has a positive significant effect on affective and behavioural customer engagement, whereas content quality has a positive significant effect on affective customer engagement. Second, customer engagement is a significant mediator through the dimensions of affective and behavioural customer engagement.

Practical implications

The findings of this study can help online modest fashion SMEs better comprehend the factors which influence the customers’ engagement for value co-creation intention whether it is subject factors or environmental factors. Therefore, they can better operate online and encourage customers to contribute to the development of new products and services and hence achieve a competitive advantage and survive in times of COVID-19.

Originality/value

Most of the existing studies focused on the value co-creation behaviour and output. However, there is limited research focusing on what contributes to the customers’ engagement for value co-creation intention, especially for online modest fashion and Muslim countries. Therefore, this study attempts to examine and bridge this research gap.

Abstract

Purpose

The purpose of this paper is to provide trilogy in the emerging market for the establishment of business, economy and environment which is the new word for the development of any nation to attain sustainable development. This research explores the prospective crowdshipper's willingness to participate in crowdshipping services through a motivational factor.

Design/methodology/approach

To understand the trend and future of this concept, Google Trends Analysis (GTA) has been used. The theoretical model has been validated empirically using a survey of 287 Indian (Generation Y and Z) urban participants, but focused is on Generation “Z” participants and subsequent analysis have been carried out using structural equation modelling.

Findings

A theoretical framework has been developed connecting the various factions of the crowdsourcing process thus providing an overall view of the process strategy for logistics start-ups. This conceptual framework of sharing economy in emerging market can benefit the prospective suppliers and their target receivers. Particularly trust in crowdshipper plays a significant mediating role between subject factors and next generation user willingness to participate in crowdshipping services for sustainable last-mile delivery.

Originality/value

The present theoretical foundations and frameworks have been studied to get an idea of the main aspects of the field. It has the potential to provide the impetus for collaboration with the various stakeholders thus achieving the sustainable development process. The practical inference of this study is the usability in terms of the plugin application for e-retailer in emerging markets.
