This study aims to estimate the regulatory compliance impact on the risk of banks operating in Pakistan. The direct and indirect regulatory compliance of conventional banks with Islamic operations in terms of risk from 2009 to 2017 are estimated.

This study used a two-step system generalized method of moment (GMM) (dynamic panel) to examine the relationship between regulatory compliance, Islamic operations and the bank risk and tested the direct and indirect impacts of regulatory compliance and Islamic operations on the said risk.

Regulatory compliance has a significant and positive relation with bank risk, whereas the Islamic bank operations have a significant and negative relationship. Thus, regulatory compliance creates pressure on banks, but the Islamic operations of conventional banks reduce this pressure in direct and indirect ways.

Per the policy of State Bank of Pakistan (SBP), banks shall pursue Islamic operations to reduce regulatory pressure and widen their scope. The results suggest that regulatory compliance creates pressure on bank risk irrespective of the type of the bank. Thus, the SBP should seek the appropriate measure for this occurrence.

To the best of the authors’ knowledge, this work is the very first study that has considered the unique Islamic operations of conventional banks and estimated its impact on risk. Moreover, this work examined two types of bank risk instead of employing stability and market measure. This research is also the first to implement a two-step system GMM for the methodology.

Corporate boards monitor managerial decisions as concluded by the monitoring hypothesis. In this scenario, the present study stresses that leverage decisions can be used as a tool to control insolvency risk.

This study aims at investigating the intervention of capital structure and debt maturity on the relationship between corporate board composition and insolvency risk by employing Preacher and Hayes’s (2008) approach. The study sample comprises 284 firms from 2013 to 2017. Structural equation modeling is used to study the direct and indirect relationships among study variables.

Results show that debt maturity is a significant mediator between CEO duality and insolvency risk and between board size and insolvency risk relationships. However, the capital structure did not mediate any of the proposed links.

This study suggests using more long-term debt to tackle insolvency risk in listed non-financial firms of Pakistan. It is also inferred that decisions regarding debt maturity are more crucial than capital structure decisions because insolvency risk is concerned.

This study evaluates the comparative mediating role of the debt maturity and the capital structure. Such role is uncommon in the literature addressing the relationship between governance variables and insolvency risk.

Perception of organizational politics is one of the key factors of the organization's performance. Based on the principles of Game Theory, this study aims to examine the impact of management's and employee's politics within an organization on the psychological and organizational stress levels of workers, followed by their task and contextual performance.

Following the non-probability convenience sampling technique, the data was collected from the managerial and non-managerial staff of public, private and semi-government services organizations in Rawalpindi, Islamabad, Lahore, Faisalabad, Gujranwala, Abbottabad and Karachi cities in Pakistan.

The structural analyses indicate that organizational politics is a major cause of stress among workers and has a significant positive impact on the psychological and organizational stress of workers. Moreover, both organizational politics and job stress hinder workers' performance.

The findings of the current research provide valuable insights into the management of firms about the destructive role of politics with a special focus on psychological and organizational stress, followed by job and contextual performance, particularly in the context of Pakistan. It also proposes strategies to counter this issue, improving worker's performance. Furthermore, the findings also suggest whether management or employees are more involved in organizational politics.

Keeping in view the diabetes status that has affected about 415 million people globally and is the leading cause of death in many countries along with therising demand for low Glycemic Index (GI) foods, the purpose of this paper is to optimize the extrusion process for the development of low GI snacks from underutilized crops like water chestnut and barley.

The extrusion parameters (screw speed and barrel temperature), feed moisture and water chestnut flour, barley flour proportion, were varied and their effects on system and product responses (specific mechanical energy, water absorption index, water solubility index, bulk density, expansion ratio and breaking strength) were studied.

All the system and product responses were significantly affected by independent variables. Response surface and regression models were established to determine the responses as function of process variables. Models obtained were highly significant with high coefficient of determination (R²=0.88). The optimum processing conditions obtained by numerical optimization for the development of snacks were 90°C barrel temperature, 300 rpm screw speed, 14 per cent feed moisture and WCF-to-BF ratio as 90:10. Shelf life studies confirmed that the developed snacks can be safely stored in HDPE bags for a period of six months under ambient conditions.

Water chestnut and barley flour did not blend till date for extrusion cooking. Such snacks shall be a viable food option for diabetic people and can act as laxative due to high fibre and β-glucan content from barley.

Low glycemic index gluten-free cookies from high amylose rice flour were prepared by modifying baking conditions and ingredient composition.

Baking temperature, baking time, and concentration of carboxymethyl cellulose (CMC) were varied between 170 and 190° C, 12–25 min, and 0.2–1%, respectively, using central composite rotatable design. The developed cookies were packed in metalized polyester pouches and stored under ambient conditions for a period of 90 days.

Width and bulk density of cookies increased significantly (p < 0.05) with an increase in baking temperature, while thickness, baking loss and yield decreased with an increase in baking temperature. Puffiness increased predominantly with the increase in the concentration of CMC. Design expert predicted baking temperature of 185° C, baking time of 22 min, and 0.8% concentration of CMC as desirable conditions for the development of gluten-free cookies from rice flour. Cookies developed after following optimized conditions recorded dietary fiber of 4.66%, resistant starch (RS) content of 7.20% and predicted glycemic index (pGI) of 44.60. RS, pGI, moisture, water activity, free fatty acids and peroxide value increased significantly, whereas hardness and overall acceptability decreased during storage.

Gluten-free (GF) foods are in high demand globally due to the prevalence of celiac disease. Rice lacks gluten protein, and thus, can serve as a potential raw material for the development of GF cookies. In the present study, the ingredient modification and freezing interventions during baking were found to be crucial if the development of low GI gluten-free cookies having good RS content is targeted. Optimized GF cookies prepared via technological intervention and packed in metalized polyester were shelf stable for up to 3 months under ambient conditions. Furthermore, resistant starch content was enhanced while the predicted glycemic index was decreased during storage. Adoption of baking conditions and CMC level optimized in the present study can help to develop shelf-stable GF bakery products for people suffering from comorbidities like celiac disease and diabetes.

Resistant starch content was enhanced while predicted glycemic index was decreased during storage of gluten-free cookies prepared from high amylose rice flour. The developed cookies can be a complementary diet to people suffering from comorbidities like celiac disease and diabetes.

Drawing on social identity theory (SIT), the current research highlights the sequential mediation effects of customer interaction, functional value and hedonic value in linking customer-brand identification and self-representation with online brand advocacy (OBA).

Data were gathered from 483 Egyptian and 595 non-Egyptian Aliexpress shopping platform customers, then analyzed using SmartPLS 4.

The multigroup analysis findings revealed that customer interaction and functional/hedonic values sequentially mediated the linkages of customer-brand identification and self-presentation with OBA for Egyptian and non-Egyptian user groups.

The novelty of this study is that it tested and validated customer interaction with the Aliexpress service scale, allowing for reflection on the interactive nature of this platform between Egyptian and non-Egyptian customers. SIT also lends credence to the idea that self-presentation mediates the effect of customer-brand identification on Aliexpress’s OBA, potentially shedding new light on this understudied dimension using a theoretical framework.

Islamic label of an organization attracts Muslims for investment. There is a rising concern with a huge profile of corporate governance related to the Islamic rules (principles). In this context, this study aims to examine the effect of Islamic labelling on corporate governance in the Pakistani setting.

This study used a panel data set comprising 120 non-financial Shariah-compliant and non-Shariah-compliant Islamic firms listed on the Pakistan Stock Exchange over the period 2013–2020. For analysis, this study used static panel data estimation techniques. Moreover, for robustness check, this study also applied the system generalized method of movements procedure.

The findings deduced from empirical estimations reveal that Islamic labelling is positively associated with corporate governance. Overall, results indicate that Islamic labelling promotes corporate governance practices in Pakistan.

It is of utmost importance in terms of both theoretical and empirical context that Pakistan is a Muslim country having a 96.5% Muslim population, and it is evident that Muslims are allowed to execute their business under the guidance of Shariah principles. This study is unique because most of the previous literature provides empirical support related to the impact of corporate governance on capital structure, profitability and firm performance in conventional and Islamic firms. Practically, there is scarce literature on this issue.

The purpose of this paper is to analyze wind characteristics and their effects on wind turbine components and energy generation at the candidate site.

The methodology covered the detailed investigation of wind characteristics using Weibull k and c parameters and standard deviation at 30 m above the ground level (AGL). The wind shear coefficient and air density were also studied. The weight model was developed to determine the effects on wind turbine components and energy generation. At last, an economic assessment was carried out to determine the pre- and post-effects of the weight model on the cost of energy per kilowatt-hour.

The mean standard deviation, Weibull k parameter and Weibull c parameter were found to be 2.157, 2.617 and 6.087 m/s, respectively, at 30 m for a period of a year. The mean wind shear coefficient was found to be 0.176 for a year. The calculated results showed that site-specific midrange and amplitude force were 40.95 per cent and 37.75 per cent on wind turbine mechanical components, respectively. The average rise in force and drop in energy was found to be 35.50 per cent and 47.55 per cent, respectively. The lift coefficient, drag coefficient and pitching moment considering values (a, 0.1 and 0.2) showed an increase in force on wind turbine components that resulted in a drop in energy. The cost assessment results showed that the cost of energy was increased from US$0.032/kWh to 0.0466/kWh for wind turbine A.

An accurate determination of the weight factor is necessary for near-reality assessment of wind energy yield and rise of force on the wind turbine. The results paved the way for site-specific design optimization of wind turbines.

The study contributes to the site-specific wind characteristic-based weight model to determine the effects of wind loads on wind turbine components and energy generation and compared with the specified design standard. The lift coefficient, drag coefficient and pitching moment coefficient show a rise in the force while considering the weight factor values. The results show that the site has the potential to generate energy at the lowest cost per kilowatt-hour, but it needs wind turbine design adjustments according to site-specific wind characteristics. If site-specific wind characteristics are considered, it would lead to maximum energy generation and high reliability of wind turbine components.

The present research was envisaged with an aim to optimize the system and the product responses for the development of tomato pomace-incorporated corn-based extrudates employing central composite rotatable design and determine its proximate, lycopene, consumer acceptability and storage studies.

Lycopene-rich extrudates were developed from corn flour blended with different levels of tomato pomace. The independent extrusion variables, namely, feed composition (95:5 to 75:25), feed moisture (12–20%), screw speed (200–600 rpm) and barrel temperature (125–185 °C), were studied to determine their influence on dependent variables, namely, specific mechanical energy, hardness, water solubility index, lateral expansion, water absorption index, bulk density and color.

All of the quality parameters were significantly (p < 0.05) influenced by independent variables. The regression models obtained for all the responses showed high coefficients of determination (R2 = 0.85–0.95). The optimum conditions for the development of tomato pomace-incorporated corn-based extrudates were feed composition (90:10), feed moisture (14%), screw speed (300 rpm) and barrel temperature (170 °C). The moisture, fat and carbohydrate contents of the extrudates were significantly reduced, whereas protein, ash and fiber were significantly (p < 0.05) enhanced after the incorporation of tomato pomace. Aluminum laminates were found to be the suitable packaging materials for extrudates for a period of 120 days in comparison to high-density polyethylene packages.

As far as the authors could possibly know, scanty literature exists wherein the tomato pomace has been utilized for the development of lycopene-rich corn-based extruded snacks. Such extrudates with significantly higher fiber and lycopene contents than corn flour will serve as a suitable alternative for the development of shelf-stable ready-to-eat extruded snacks.

Currently, there is a great demand for those food products that are easy to prepare or ready for direct consumption. Making pear fruit/juice available round the year is desirous owing to pears' high-nutritional value and specific pleasant taste. Pear is, however, a seasonal fruit and under ambient conditions has a limited shelf life rendering it available as fresh fruit for a specific period.

The study aimed to optimize the spray drying process parameters using response surface methodology for the development of pear juice powder. The process variables included the inlet air temperature of 140–210°C, maltodextrin levels of 4–25%, atomization speed of 11,400–28,000 rpm, feed flow rate of 180–630 mL/hr, and feed total soluble solids (TSS) of 13–30°Brix. The dependent responses were powder yield, solubility, antioxidant activity {% 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity}, dispersibility, hygroscopicity and particle density.

Among independent variables, inlet air temperature showed a predominant effect. The optimum processing conditions for the development of pear juice powder with optimum quality were 163.02°C inlet air temperature, 13.50% maltodextrin, 28,000 rpm atomization speed, 390.94 mL/h feed flow rate, and 25.5°Brix feed TSS. Under these optimum conditions, pear powder with desirable properties could be produced. The experimental and predicted values were found to be in agreement, indicating the suitability of the model in predicting optimizing responses of pear powder. Glass transition temperature of pear powder was found to be 36.60 ± 0.40°C, which is much higher than that of ambient temperature, suggesting better shelf stability.

The processing of pear fruit has resulted in the increased demand for pear juice powder in both domestic and international markets as a primer of new food products. The optimum conditions obtained in the current study could provide a new insight to the food industry in developing spray-dried pear powder of optimum quality. This can open up a new horizon in the field of food industry for the common masses of Jammu and Kashmir, India.
