During any design phase, the associated process variations and uncertainties can cause the design to deviate from its expected performance. The purpose of this paper is to propose a robust design optimization (RDO) strategy for the 3D grain design of a dual thrust solid rocket motor (DTRM) under uncertainties in design parameters.

The methodology consists of design of 3D complex grain geometry and hybrid optimization approach through genetic algorithm, globally and simulated annealing, locally considering the uncertainties in design parameters. The robustness of optimized data is measured for a worst case parameter deviation using sensitivity analysis through stochastic Monte Carlo simulation considering variance of design parameters mean.

The important achievement that can be associated with this methodology is its ability also to evaluate and optimize the propulsion system performance in a complex scenario of intricate 3D geometry under uncertainty. The study shows the objective function to maximize the average thrust in dual levels could be achieved by the proposed optimization technique while satisfying constraints conditions. Also, this technique proved to be a great help in reducing the design space for optimization and increasing the computational quality.

This is the first paper to address the dual thrust solid rocket motor grain design under uncertainties using robust design and hybrid optimization approach.

The purpose of this study is to analyze the factors affecting startup development and the entrepreneurship ecosystem's contribution to it.

A quantitative methodology is used for data collection from different startup owners working across Pakistan. It is a cross-sectional descriptive study, which investigates the causal effect of variables at a definite point in time. Non-probability convenient sampling was used for selecting available startups from the incubation centers. The sampling framework consists of the founders of the startups that have been previously incubated at any of the selected incubation centers.

Regression analysis results from 165 responses of entrepreneurs and incubation centers demonstrate that the most important factors affecting startup development were financial access, government support, marketing challenges, education, technology and managerial skills in order of occurrence. Entrepreneurship ecosystem also proved to have a very positive impact on the relationship of these factors with startup development.

In this paper, the factors that affect the development of startup are analyzed and recommendations are provided.

This research is comprehensive, as we have collected data from actual entrepreneurs and incubation centers to explain how entrepreneurs initiate their startup business by considering their managerial skills. As such, this study is unique in that the data comes from newly developed incubations centers in one of South Asia's fastest-growing economies.

The aim of the paper is to determine the asymmetric impact of tourism on the deficit in the balance of payments (BOPs).

The research uses the non-linear autoregressive distributed lag (ARDL) model to investigate the asymmetric impact of tourism on Pakistan's BOPs deficit using quarterly data from 1995 to 2019.

The finding reveals that due to the positive change in tourism, the BOPs deficit decreases by 27%, although due to the negative change in tourism, the BOPs deficit rises by 2.3%. In addition, the significance of F-statistics (10.609) confirms the existence of co-integration between tourism and the deficit in the BOPs. The Wald test confirms the asymmetric association between tourism and the deficit in the BOPs over the long term.

In order to improve tourism in Pakistan, policymakers must consider the following implications. First, there is a need for an adequate infrastructure that can help the tourist. Second, the Government must maintain a stable law and order situation as a whole and particularly at tourist destinations. Finally, the Government should develop tourism-friendly policies in order to boost tourism in Pakistan.

The research provides new evidence of the impact of tourism on the BOPs using the novel non-linear ARDL (NARDL) technique. The evidence will help policymakers to develop policies to improve tourism in order to reduce the BOPs deficit.

In recent times, mobile banking has become the best alternative for transactions associated with payments like bills, fees, and peer-to-peer payments. Therefore, the pace of adoption is increasing day after other. However, the numbers of customers are not equal to the expectations as there are several challenges and threats hindering in the way of excellence and growth of mobile banking. Therefore, this chapter has been written purposively to address all the elements that are associated with the use of mobile banking with special emphasis on Pakistan and other developing sides of Asia. In fact, concern towards Asian sides is mandatory as the continent has the massive charm to attract users towards the use of mobile banking, but there is a need for proper policy and concern from stakeholders in order to give a push to the technology, which is fruitful for society, environment, as well as economy. The study includes an in-depth discussion on factors that need attention to make the study implicative and thorough for conducting further research in the field of Fin-Tech and mobile banking.

This study aims to find the determinants of internal and external customer satisfaction of Islamic banks of Pakistan through service quality indicators that are assurance, reliance, empathy, tangibility, responsiveness. Compliance has also been added as a determinant of customer satisfaction. In this study, customers are divided into two groups, internal customers are those who are an employee in the Islamic bank and also an account holder. While external customers are account holders only in Islamic banks of Pakistan.

In this study, a quantitative research approach is used for analyzing the behavior of internal and external customers of Islamic banks in Pakistan. The instrument which is used to analyze the study’s data, is a structured five-point Likert-scale questionnaire. The structural model was analyzed with the help of the partial least squares structural equation modeling approach.

This study concluded that internal customers of Islamic banking are well aware and have full information and their level of satisfaction is positive toward the bank’s services. While external customers feel satisfied while using the Islamic banking services in Pakistan. Service quality indicators are positively and significantly related to customer satisfaction in the external customer model. On the other hand, some of the indicators are not showing a significant impact on the internal customer multi-group analysis shows a difference of coefficients are insignificant between internal and external customers.

This study helps policymakers, to understand the behavior of internal and external customers of Islamic banking in Pakistan for creating favorable policies for an interest-free banking service.

This research study provides an analysis of the customer satisfaction of Islamic banks in Pakistan by dividing Islamic bank customers into two groups (internal and external customers). The purpose for dividing Islamic bank customers into two groups is that this study wants to highlight that external customer’s perception is the same as internal customers or not? Before this study, it is difficult to find single research on this topic, whereas only one study is find-out on the factors that affect internet banking adoption among internal and external customers.

Green practices are essential for sustainability. However, it is challenging due to the socioeconomic and environmental concerns. Similarly, after the induced SDG-12 and SDG-13 by United Nations, the pressure groups forced manufacturers to consider sustainability. Therefore, this research aims to examine the sustainability through multifaceted green functions in manufacturing is examined.

Data were collected from 293 supply chain professionals of manufacturers from a developing economy. Hypotheses were tested through a quantitative method using partial least squares-structural equation modeling with the help of SmartPLS version 4 to validate the measurement model.

The findings revealed that all six direct hypotheses were supported. However, out of four hypotheses of mediation, one was not supported. Besides, a sequential mediation of green supply chain environmental cooperation and green human resource management was supported. The findings illustrated that green supply chain practices positively influence all used variables.

This research provides practical insight to practitioners to implement green practices in their supply chain networks for social, economic and environmental sustainability and compliance with SDG-12 and SDG-13. The sustainability was validated in a higher-order construct (HOC) (formative), including sequential mediation in the model with the support of resource dependency theory. Therefore, this study adds substantial literature to the existing body of knowledge.

This research provides an interdisciplinary framework by adding knowledge to the Resource Dependency Theory to address Sustainable Development Goals-12 (SDGs) and SDG-13. Likewise, this research provides an extension towards the body of knowledge on the issue, which can be used in future research and critical examinations for cleaner and sustainable production. So far, in Pakistan, no research has looked at the function of these integrated variables in the manufacturing industry with a diligent focus on sustainability as it was validated in a higher-order construct (formative) with one sequential mediation, which makes this research unique.

Organisational cynicism (OC) is a growing trend in contemporary organisations. However, its impact on employee performance (EP) remains understudied. The purpose of this paper is to address this gap by investigating its effect on EP. The study also investigates the moderating effect of employee engagement (EE) on the relationship between OC and EP.

Primary data are collected through questionnaire from employees (N=200) of various health organisations in Pakistan by employing a convenient sampling technique. Hierarchical multiple regression is employed by using SPSS.

The findings of correlation and regression analyses reveal that OC has significant negative relationship with EP. Hence, the patient care is compromised in sampled organisations due to poorer performance of employees. Moreover, findings also reveal that EE has a moderating effect on relationship between OC and EP. Therefore, hospital management needs to increase EE to reduce the cynicism and improve performance. In addition, organisations and managers need to consider their role and actions creating the conditions that lead to cynicism among employees and should take trustworthy steps to increase employee retention and engagement and, ultimately, their performance. Moreover, the findings of the study indicate that the majority of respondents are not happy with their organisations. They also feel that the organisation is not fulfilling its promises and betraying them in several ways. This breach of contract becomes the reason for OC among employees and badly affects their performance. Most of respondents give importance to their career development and the findings reveal that organisations are not focussing on career development of their employees.

The study has some limitations and implications. The organisational culture can mitigate the negative effect of OC and enhance performance by promoting EE. It is recommended that employee cynicism can be reduced by providing a supportive environment, EE and fairness. Nevertheless, the findings of this study still help supervisors to inhibit this harmful effect by reducing the level of psychological contract violation and organisational politics that will reduce the level of cynicism among employees and improve their performance.

It is found that OC has a major impact on the behaviour and attitude of employees, supervisors and representatives on the one hand and, ultimately, the organisation, on the other hand. These effects have specific susceptibilities due to the vicinity of the employees. It is recommended that employee cynicism can be reduced by providing a supportive environment.

The study also helps psychologists to understand employees’ attitudes and improve personnel selection to ensure they recruit the right people. Leaders need to communicate honestly, effectively and frequently to address cynicism in order to ensure ample staffing and resource levels that result in good patient care and positive work attitudes at hospitals.

According to the researchers’ best knowledge, only few studies tried to investigate the relationship between organisational cynicism and EP by employing the moderating effect of EE. Therefore, it will be a good contribution in existing literature to understand consequences of cynicisms.

Organizational cynicism is a growing trend in contemporary organizations. However, its impact on employee performance remains understudied. The purpose of this study is to address this gap by investigating the effect of three dimensions of organizational cynicism (cognitive, affective and behavioral cynicisms) on employee performance. The study also investigates the moderating effect of employee engagement on the relationship between three types of organizational cynicism and employee performance.

Primary data are collected through questionnaire from employees (N = 200) of various health organizations in Pakistan by using a convenient sampling technique. Hierarchal multiple regression models are used by using SPSS.

The findings reveal that all three types of organizational cynicism (i.e. cognitive cynicism, affective cynicism and behavioral cynicism) have a significant negative relationship with employee performance, while employee engagement moderates this relationship. Moreover, the findings indicate that the majority of respondents are not happy with their organizations. They have the feeling that their organizations are not fulfilling their promises, in fact, are betraying them in different ways. This breach of contract becomes the reason for organizational cynicism among employees and negatively affects their performance at work.

The study has a large population size and it is quite difficult to address the whole population and collect data from a large sample because of time and limited budget.

The organizational culture can mitigate the negative effect of organizational cynicism and enhance performance by promoting employee engagement. The study helps psychologists to understand employees’ attitudes and improve personnel selection to ensure they recruit the right people. Openness, honesty and early communication can increase predictability and controllability of future events.

The job insecurity and lack of adequate compensation are assertive factors towards low productivity and negative attitude toward organization.

According to the researchers’ best knowledge, only few studies tried to investigate the relationship between organizational cynicism and employee performance by using the moderating effect of employee engagement. Therefore, it will be a good contribution in existing literature to understand consequences of cynicisms.

The purpose of this paper is to examine the mediating role of trust in the relationship between knowledge management enablers (i.e. top management support, organizational culture, knowledge management system quality, and openness in communication) on knowledge sharing in small and medium enterprises (SMEs) in Pakistan.

The study was conducted through self-administered survey of employees of SMEs in Pakistan. Correlation, Baron and Kenny approach (causal steps approach) and PROCESS Macro (normal test theory) developed by Hayes were used to find out the direct and indirect effects of trust among knowledge management enablers and knowledge sharing.

The results have shown that trust of employees at SMEs was developed through knowledge management enablers which promote knowledge sharing. Therefore, the relationship between knowledge management enablers, trust, and knowledge sharing is positive.

The current study only considered the single aspect of knowledge management system, i.e. knowledge sharing; some other aspects of knowledge management system such as knowledge creation and knowledge utilization can be used for future studies at SMEs sector.

The mediation of trust between top management support, culture, openness in communication, and knowledge sharing provided that trustworthy relationships between the members of an organization would lead to enhance the knowledge sharing activities. In order to promote the knowledge sharing attitudes within the organization, the managers should consider knowledge management enablers (top management support, organizational culture, and openness in communication) along with trustworthy environment as an energetic force for the development of knowledge management systems.

The study confirmed the mediating effect of trust between the relationships of top management support, organizational culture, openness in communication, and knowledge sharing, while there is a partial mediating role of trust between knowledge management system quality and knowledge sharing.
