The coating process is broadly employed in the manufacturing of wallpapers, adhesive tapes, wrapping, protection of fabrics and metals, X-ray and photographic films, beautification, books and magazines, film foils, magnetic records, coated paper, etc.

In this study, an incompressible flow of non-Newtonian fluid is modeled to inspect the rheological behavior of finite coating thickness in the reverse roll coating process. With the assistance of lubrication approximation theory (LAT), the dimensionless form of governing expressions is simplified. Exact solutions for distributions for velocity, flow rate, temperature and pressure gradient attained utilizing perturbation technique and their variation is presented as well as discussed in graphs. Meanwhile, some important factors from an engineering perspective including coating thickness and transition point were calculated mathematically and are displayed in a tabular manner. Also, streamlines are drawn to observe the flow pattern.

Prandtl fluid parameters provide a controlling factor to regulate the flow rate, velocity, coating thickness, and pressure gradient leading to an efficient coating process. Moreover, the Brinkman number and Prandtl fluid parameters significantly improve the temperature distribution.

In the literature, this study fills a gap in the theoretical prediction of coating thickness rheologically influenced by Prandtl fluid in reverse roll coating process.

This study aims to examine the impact of stock mispricing on corporate investment decisions by taking the sample of non-financial firms listed on the Pakistan Stock Exchange during the period of 2008-2014.

To measure the mispricing, this study decomposes the market-to-book ratio into mispricing and growth components and measures corporate investment by capital expenditures. Fixed and random effect panel regression models are used to estimate the results.

Results of the study show that firms issue overvalued equity to finance the capital expenditures. Consistent with other studies, the relationship between stock mispricing and investment is more prominent in the financially constrained firms. In addition, cash flow investment sensitivity is higher in financially unconstrained firms.

Nonetheless, the results give important implications to the Pakistan Stock Market on how the mispricing enhances the welfare by relaxing the financial constraints and allowing the managers to make investment in profitable projects that otherwise go non-funded. These findings have interesting implications for further research in the literature of finance and also help in economic policy-making.

This study finds the impact of stock mispricing on corporate investment decisions by considering the role of market timing in the context of Pakistan.

The purpose of this study is to finds out how investor attention plays the moderating role between the relation of information risk and COE by considering the effect of three different types of information risk, that is private information, lack of quality and transparent information.

For that purpose, data is collected from all the non-financial firms listed on PSX from 2007 to 2019. Two-step system GMM dynamic panel estimators are applied to test the dynamic nature of the proposed model.

The findings of the study show that investor attention reduces these three information risks by increasing the stock liquidity and decreasing the crash risk which ultimately decreases the COE. Also, this study examined the role of investor attention between the relations of information risk and corporate investment in the dynamic panel model, where the two-step system generalized method of the moment has been applied. The finding of the study shows that investor attention stimulates the innovative investment by increasing investor confidence and decreasing the agency conflict.

This study contributes to the literature by providing the novel findings by considering the role of investor attention in reducing the effect of three different types of information risk, that is private information, less quality as well as less transparency of information and further their effect on the cost of equity.

The purpose of this paper is to evaluate the frequency and antimicrobial susceptibility pattern of pathogens present in ready-to-eat salads available at a local market.

A 100 salad samples were collected aseptically. Each sample (25 g) was homogenized in 225 ml of sterile peptone water and was serially diluted up to 1×106. Dilutions were inoculated on nutrient agar by surface spread plate technique. Aerobic colony count (ACC) was estimated by counting the colonies. Bacterial isolates were cultured on blood and MacConkey agar and identified on the basis of their morphology, culture characteristics and confirmed by API 20E and 20NE. Antimicrobial susceptibility was determined as per CLSI 2014.

ACC range was 1.1×103 cfu/g to 5.8×109 cfu/g. Among these the highest ACC was found in channa chat (4.9×104 to 5.8×109 cfu/g). A total of 127 microorganisms were identified; 73 were gram negative rods (GNRs) and 24 were gram positive cocci (GPC). Among GNRs; Klebsiella spp. (n=18) was the predominant whereas among GPC, Staphylococcus aureus (n=6) were the chief pathogen. Klebsiella spp. showed 100 percent resistance to ampicillin, 89-78 percent to amoxicillin/clavulanic acid and 33 percent to imipenem, however, Enterobacter spp. were resistant to ampicillin (100 percent) amoxicillin/clavulanic acid (77 percent) and imipenem (23 percent). Staphylococcus aureus showed resistance to co-amoxiclav (83 percent) and penicillin (75 percent).

This study revealed that effective control measures must been implemented and respected by throughout the entire food chain and better surveillance studies should be performed at national level to reduce the spread of bacteria by fresh salads.

This paper explore the high prevalence of multidrug-resistant pathogens in different salads and most of the salads were found to be unhygienic for consumption.

This research paper aims to handle the effects of economic growth, corruption, energy consumption as well as trade openness on CO2 emissions for a sample of West African countries during the period 1980 and 2018.

The current work uses the pooled mean group (PMG)-autoregressive distributed lag (ARDL) panel model to estimate the dynamics among the different variables used in the short and long terms.

The findings demonstrate that all variables have long-term effects. These results suggest that gross domestic product (GDP) per capita exhibits a positive and prominent effect on CO2 emissions. Corruption displays a negative and outstanding effect on long-term CO2 emissions. In contrast, energy consumption in West African countries and trade openness create environmental degradation. Contrarily to long-term results, short-term results demonstrate that economic growth, corruption and trade openness do not influence the environmental quality.

Empirical findings provide useful information to explore deeper and better the link between the used variables. They stand for a theoretical basis as well as an enlightening guideline for policymakers to set strategies founded on the analyzed links.

Thermal and species transport of magneto hydrodynamic Casson liquid over a stretched surface is investigated theoretically in this examination for the three-dimensional boundary layer flow of a yield exhibiting material. The phenomenon of heat and species relocation is based upon modified Fourier and Fick’s laws that involves the relaxation times for the transportation of heat and mass. Conservation laws are modeled under boundary layer analysis in the Cartesian coordinates system. The purpose of this paper is to find the influence of different emerging parameters on fluid velocity, temperature and transport of species.

Reconstructed nonlinear boundary layer ordinary differential equations are analyzed through eigenvalues and eigenvectors. Due to the complexity and non-existence of the exact solution of the transformed equations, a convergent series solution by the homotopy algorithm is also derived. The reliability of the applied scheme is presented by comparing the obtained results with the previous findings.

Physical quantities of interest are displayed through graphs and tables and discussed for sundry variables. It is discerned that higher magnetic influence slows down fluid motion, whereas concentration and temperature profiles upsurge. Reliability of the recommended scheme is monitored by comparing the obtained results for the dimensionless stress as a limiting case of previous findings and an excellent agreement is observed. Higher values of Schmidt number reduce the concentration profile, whereas mounting the values of Prandtl number reduces the dimensionless temperature field. Moreover, heat and species transfer rates increase by mounting the values of thermal and concentration relaxation times.

The phenomenon of heat and species relocation is based upon modified Fourier and Fick’s laws which involves the relaxation times for the transportation of heat and mass. Conservation laws are modeled under boundary layer analysis in the Cartesian coordinates system.

This research focuses on the distinct group of high-status employees commonly referred to as workplace vigilantes, and conceptually investigates how unethical requests by these individuals impact the behavior and attitude of other employees over time using the social identity theory.

For developing a conceptual model, literature from the domains of social identity, organizational behavior and general management was searched through Google Scholar. To search the literature, some key terms such as “unethical activities”, “Islamic work ethics” and “social identity” were searched and analyzed.

Using the social identity theory, a conceptual process model is developed which suggests that when high-status employees propose unethical requests to employees, individuals with high morality are likely to refuse those unethical requests to protect their self-categorizations. However, taking the unfair advantage of their illegitimate powers, high-status employees are likely to eventually make wrong judgments and give unnecessary punishments to moral employees. It is further argued that consistent victimization is likely to negatively impact the social identity of such employees and leads to irritability in moral employees, particularly when such individuals are unable to get the requisite social support from their leaders.

While a considerable body of literature has focused on the antecedents and consequences of intense unethical business practices and the crucial role of leaders in such activities, limited attention has been given to the role of other employees and how they engage in mild unethical misconduct regularly, which is the key focus of this research. The novel conceptual framework needs to be tested in diverse contexts for further development and validation.

TikTok social media app has become one of the most popular forms of leisure and entertainment activities, but how hedonic consumption experiences (comprising fantasy, escapism, enjoyment, role projection, sensory, arousal and emotional involvement) of the TikTok app determine users' intention to use the app and its resulting impact on the actual usage behavior remains limited in the information systems literature, especially featuring the hedonic consumption perspective in entertainment industry.

This study employs uses & gratification theory to answer the “why” via predicting the role of hedonic consumption experiences that serve as gratifications to trigger technology acceptance behavior (especially, in form of users' behavioral intention to use the TikTok app and its further impact on usage behavior). This study utilizes the partial least squares-structural equation modeling approach to perform data analyses on 258 TikTok app users.

Our results provide a strong support such that users' playful consumption experiences (i.e. escapism, role projection, arousal, sensory experience and enjoyment) positively influence their intention to use the TikTok app and its resultant effect on users' actual usage of the app. In contrast, fantasy and emotional involvement fail to influence users' intention to use the TikTok app.

To the best of our knowledge, our investigation is one of the first studies to apply the hedonic consumption experiences as potential gratifications that derive users' intention and its subsequent influence on the actual usage of the TikTok app. Our study results would assist marketing and brand managers to redefine approaches and tactics to create effective strategies that implement essential determinants to increase behavioral intention among entertainment service providers.

The purpose of this study is to examine the factors affecting deposit withdrawal intentions among Moroccan profit-sharing investment account holders.

Applying the push-pull-mooring (PPM) theory, a quantitative survey, based on insights brought to light by a previous qualitative study, was developed and administered to 166 depositors from five participatory banks at branches located in Morocco. Structural equation modeling was then used to evaluate the significance of relationships between the various variables under study.

Empirical findings showed that the PPM model with a second-order construct structure exhibited a better representation of the observed variables as compared to a first-order factor model. The results of the structural analysis indicated a significant direct relationship between withdrawal intention and each of the PPM model constructs: push and pull factors were found to have a positive impact on withdrawal intention, while mooring factors had a significant inverse relationship with withdrawal intention. The results of this study also revealed that the moderating role of the mooring construct was found in both relationships between push and withdrawal intention and between pull and withdrawal intention.

The absence of a longitudinal study measuring the actual withdrawal behavior is the main limitation of this study. Furthermore, withdrawal intention was examined without differentiating between individual and corporate depositors. Finally, despite being insightful, the empirical findings should be generalized with caution, as the sample was purposely chosen by the banks’ management.

This study implied that participatory banks should stress the importance of mooring factors, as they strongly inhibit depositors’ intention to shift their funds to the conventional banking system. Moreover, this study provides great indications to Moroccan regulators and policymakers on a number of issues that can be used to develop policies that could improve the participatory banking system.

To the best of the authors’ knowledge, this study represents the first attempt to confirm the effectiveness of the PPM model in examining depositor-withdrawal intentions. This study is also the first of its kind to address profit-sharing investment depositors’ apprehensions in the Moroccan context, to the best of the authors’ knowledge.

This study aims to empirically explore and compare the dynamic dependency between health-care sector and Islamic industries before, during and after the COVID-19 pandemic.

Time-varying student-t copula is used for before, during and after COVID-19 periods. The data used are the daily frequency price series of the selected markets from February 2017 to October 2023.

Empirical results found strong evidence of significant impact of the COVID-19 pandemic on the dependence structure of the studied indexes: Co-movements between various sectors are certain. The authors assist also in the birth of new dependence structure with the health-care industry in response to the COVID-19 crisis. This reflects the contagion occurrence from the health-care sector to other sectors.

By specifically examining the Islamic industry, this study sheds light on the resilience, challenges and opportunities within this sector, contributing novel perspectives to the broader discourse on pandemic-related impacts on economies and industries. Also, this paper conducts a comprehensive temporal analysis, examining the dynamics before, during and after the COVID-19 lockdown. Such approach enables an understanding of how the relationship between the health-care sector and the Islamic industry evolves over time, accounting for both short-term disruptions and long-term effects. By considering the pre-pandemic context, the paper adopts a longitudinal perspective, enabling a deeper understanding of how historical trends, structural factors and institutional frameworks shape the interplay between the health-care sector and the Islamic industry.
