This study aims to present a unique hybrid metaheuristic approach to solving the nonlinear analysis of hall currents and electric double layer (EDL) effects in multiphase wavy flow by merging the firefly algorithm (FA) and the water cycle algorithm (WCA).

Nonlinear Hall currents and EDL effects in multiphase wavy flow are originally described by partial differential equations, which are then translated into an ordinary differential equation model. The hybrid FA-WCA technique is used to take on the optimization challenge and find the best possible design weights for artificial neural networks. The fitness function is efficiently optimized by this hybrid approach, allowing the optimal design weights to be determined.

The proposed strategy is shown to be effective by taking into account multiple variables to arrive at a single answer. The numerical results obtained from the proposed method exhibit good agreement with the reference solution within finite intervals, showcasing the accuracy of the approach used in this study. Furthermore, a comparison is made between the presented results and the reference numerical solutions of the Hall Currents and electroosmotic effects in multiphase wavy flow problem.

This comparative analysis includes various performance indices, providing a statistical assessment of the precision, efficiency and reliability of the proposed approach. Moreover, to the best of the authors’ knowledge, this is a new work which has not been explored in existing literature and will add new directions to the field of fluid flows to predict most accurate results.

The purpose of this study is to identify the role of social media in implementing effective organizational change. The study illuminates how social media applications support the antecedents of organizational change in the workplace.

The study followed an interpretive approach based on qualitative design and grounded theory using 41 non-directive and semi-structured interviews with change leaders and change recipients. These respondents were chosen using purposive sampling and thematic analysis was then performed using NVivo 11-Plus software.

This research highlights how social media applications can be used to overcome the challenges of organizational change implementation. The findings of the study illuminate various emerging themes such as social media applications are beneficial for fostering knowledge sharing about change processes and enhancing effective communication during change formulation and implementation. It can increase the level of trust and participation in decision-making and decrease the level of resistance to change. Also, it can enhance the level of support for change acceptance in the workplace.

Social media application (SMAs) are helpful to foster informal, constructive and relevant discussion with respect to routines organizational tasks, employee concerns about new changes, information about job security and financial and non-financial benefits after change implementation. The effective and efficient use of SMAs helps organizations to foster knowledge amongst employees and they can address various critical issues i.e. employee uncertainties about change initiatives, social consensus on the solution of problems and interactive communication among social actors within a network.

The study represents an effort to explore seldom-researched aspects such as the role of social media in the context of change formulation and implementation at the workplace. Social media applications have become popular across the world and the speed of their usage is rising day by day, but their real contribution toward organizational change has not yet been fully understood.

The failure rate of change is high amongst countries and cultures where collectivism, destructive politics and resistance are high. Therefore, change leaders are more focused on exploring how they can create networking and socialization amongst major organizational stakeholders that can minimize detrimental cynicism and lobbying during change implementation. This study is an attempt to shed light on how Social Networking Applications (henceforth SNAs) can facilitate change implementation processes in the insurance sector.

The individual reaction and interaction realities during the change process cannot be discovered once and for all as there are varied perspectives on the same subjects. Therefore, a social constructionist position was used to understand the different realties of change managers and change recipients using the context of insurance sector.

The study documented how SNAs can play an active role in addressing the concerns of employees as well as managing and protecting knowledge sharing to facilitate the change implementation process. The collaborative and interactive nature of SNAs can enhance richness in knowledge sharing and can facilitate the participation of employees. Therefore, management should monitor these platforms as a means to improve the change process and to address the concerns of employees. These networking channels which include WhatsApp and Facebook can enhance social interactions, support and acceptance at individual and organizational levels.

Social media has become a familiar tool for employees to use to discuss internal changes and policies within their organizations. Social media enhances the richness, reach, knowledge exchange and effective internal communication potential amongst organizational change stakeholders. Using social media, change recipients are now more empowered and connected with their leadership that ever before. It is now easier to facilitate decision making during the change formulation and implementation process.

Social media applications have become necessary to ensure incremental and radical changes to the survival of dynamic businesses. The findings of this study are beneficial for change leaders and recipients of change to implement successful organizational change using social media tools. The effective and efficient use of social media applications helps organizations to foster knowledge amongst employees and they can address various critical issues, that is resistance to change, lower levels of knowledge sharing and support for change acceptance and lack of employee participation in decision making.

There is an inadequate understanding regarding how SNAs play a role in facilitating the change process in both public and private sector organizations. This study offers a social mchange facilitation model with the help of social learning, social networking and social behaviourism theories.

The purpose of this paper develops a conceptual model of social influence for Internet banking adoption (IBA) using social networking platforms (SNPs). It identifies the antecedents of social influence that can positively and negative influence the IBA among a targeted population of conventional and Islamic banks. Moreover, this paper contributes various factors to social influence theory with the purpose of enhancing its implication in the context of Internet banking uptake in developed and developing countries.

This study uses a social constructivism approach to understand customer experiences, thoughts, knowledge, awareness and perceptions in relation to IBA. For this study, data were collected from 30 respondents using semi-structured interviews and purposive sampling.

Social influence comprises customer recommendations, suggestions, ratings, reviews, experiences and thoughts regarding the IBA of Islamic and conventional banks. The findings reveal that social reviews, social experts, social consensus, social responsibility and social perceptions are the key antecedents of social influence that can enhance IBA of SNPs. The research finds that positive social reviews, expert support, consensus, social responsibility and social perceptions are significant in relation to conventional Internet banking. The respondents revealed serious concerns about the privacy of their personal and financial information especially in relation to Islamic banks.

The effective and well-organized use of SNPs can foster service reviews, word of mouth, higher levels of service awareness, interactive communication, social consensus and social trust to drive the adoption of Internet banking. This study proposes the conceptual model which has positive business implications and provides the banks direction to use the SNPs to their advantage to influxes their customers to adopt the use of Internet banking.

Most previous studies have used technology acceptance model, theory of planned behavior and unified theory of acceptance and the use of technology theories in the adoption of technology and IBA. These theories have not fully illuminated the role of social content as a way to enhance or decrease the number of customers in conventional and Islamic banks. This study develops social influence theory by exploring several dimensions (i.e. social reviews, awareness, consensus, cooperation and experts support) in the context of IBA for users of SNPs. Social influence can create more reviews and can lead to more prepurchase information. It can drive customer inquiries and engagement and can inform purchase decisions for IBA. On the other hand, it can motivate existing customers of Islamic banks to use conventional banking services due to effective word of mouth.

The monetary and psycho-social ramifications of the COVID-19 pandemic have been extensive and unimaginable around the globe. The purpose of this study was to have a psycho-social analysis of people confronting this situation and its impact in the situation of a health crisis on them.

In the current study, participants were divided according to their different backgrounds and professions based on the types of measures taken by the Pakistani government to limit the spread of the virus and people who are not disturbed by any of the measurement categories but are troubled by the coronavirus. The interviews based on five open-ended questions were conducted with the eight participants, comprising questions that helped participants in remembering and realizing the purpose of the interview in the mode of an open questioning. Phenomenological interpretative analysis was used to understand how participants make meaning of the phenomenon being studied, an in-depth analysis of the human subject was considered in its singularity, and personal accounts and experiences were noted regarding this pandemic.

The results indicated that the participant’s experiences were marked by stress, insecurity, anger, fear, anxiety, traces of painful emotions and a feeling of weakness. Also the prevalence of unknown precariousness and vulnerability of coronavirus aggravated the psychological frailness among people existing in an anxiety-prone situation created by the novel coronavirus. Confronted with these painful experiences, the participants however, used a variety of cognitive and behavioral efforts which needs to be strengthened by psychological care.

This study based on qualitative method was performed on diverse socio-professional levels, giving an insight to what they are undergoing, their current fears, desires and their feeling. The outcome of this study reveals traces of uncertainty, anxiety, fears, insecurity and hidden imminent death from coronavirus, therefore highlighting a need for immediate psychological interventions.

This study explores the individual understanding regarding current coronavirus pandemic situation on subjective lived experiences and psychological health in an anxiety-prone context manifested by the health crisis created by the novel corona virus.

The purpose of this paper is to focus on the indigenous need for public health challenges being faced by the patients in Pakistan because of vertigo symptoms. Vertigo or benign paroxysmal positional vertigo is described as short episodes of dizziness (spinning sensations) that are caused because of movements of head in varying directions. Various published accounts have linked vertigo to psychological and psychiatric symptoms, which include stress, anxiety and depression. The aim of present study is to examine the validity and reliability of Dizziness Handicap Inventory (DHI) Urdu version that is vital in the diagnosis, evaluation and treatment of patients coming in hospitals.

This present study included two segments, namely, preliminary and main study. Preliminary study results indicated that the overall scale had high internal consistency of DHI Urdu version α = 0.95. The overall scale retained a high test-retest correlation tested over a period of 15 days (r = 0.93). Main study was performed on 222 vestibulocochlear disorder patients having chief complaints of tinnitus and vertigo, age ranged from 18 to 89 (M = 46.14; SD = 16.64) and recruited from various hospitals of Islamabad and Rawalpindi, Pakistan. Purposive sampling technique was applied based on cross-sectional design.

Significant correlations were noted between dizziness symptoms rating on the translated scale. Confirmatory factor analysis was used to determine the structure of the scales; an orthogonal rotation (Varimax) was conducted on the data collected from patients. A three-factor solution was obtained for DHI, the factors obtained were associated to the subscales vestibular handicap, vestibular disability and visuo-vestibular disability, demonstrating a strong factorial validity in the Pakistani cultural context.

Vertigo is a symptom that initiates various psychological issues among vestibulocochlear disorder patients (patients having ear related problems) around the world and therefore the investigated inventory offers an initial assessment for the severity of dizziness. Current research will help in the development of indigenous measures to ascertain the severity of the symptoms triggering various other mental health-related issues.

Customers are interested in finding service recommendations, reviews and word of mouth using social networking platforms. These service reviews are useful for enhancing service quality, level of information and engagement, and purchase intention of customers. The purpose of this paper is to uncover which social networking platform is more useful for the exchange of service reviews and how organizations are improving purchase intention as well as service quality in the light of customer’s reviews/experiences.

The study is exploratory in nature because it aims to understand the use of social networking platforms for enhancing service quality and the purchase intention of customers using a purposive sampling technique. To meet the objective of this study, non-directive and semi-structured interviews have been conducted with customers and marketing teams in the banking sector and internet service providers.

The results show that social networking websites are helpful in fostering responsiveness, awareness, assurance, reliability and empathy. However, respondents revealed serious concerns regarding the privacy of personal and financial information especially in the context of the banking sector. It has been found that official Facebook pages of service-providing organizations, open and closed local community Facebook groups, sponsored ads and promotional advertisements on Facebook, WhatsApp groups and YouTube video comments are more frequently used to exchange service reviews (i.e. influence the process of purchase decision) among friends, friends of friends, family members and the general public. The selected customers and market team respondents revealed that local community Facebook groups (i.e. open groups and closed groups) have gained prime importance for enhancing service quality and purchase decisions.

The effective and well-organized use of social networking platforms can foster service reviews, word of mouth, level of service awareness, interactive communication, intention to purchase, social influence, social trust and services quality. Furthermore, online social networking platforms require a lower level of advertisement costs and offer huge amounts of information, discussions, enquires, service stories, word of mouth, transactions and interactions of consumers.

The present study is exploratory in nature because it selects an under-researched issue regarding the use of social networking applications to enhance levels of purchase intention and service quality. There is limited literature which has combined the multiple constructs in a single study (i.e. social media platforms, cross-platform platforms, service quality and purchase intention of consumers). Most of the previous studies are dependent on various dimensions of service quality (i.e. “reliability, responsiveness, assurance, empath and tangibles”). However, the present study extracted that respondents have given more preferences of services awareness and privacy compared to traditional elements of service quality.

Many organizations are struggling to achieve competitiveness due to lack of knowledge sharing (KS) practices. The sustainability of the service sector is linked to KS practices and creativity. Therefore, to survive in a dynamic business environment, universities have to formulate and implement such practices and innovative learning systems. This paper aims to highlight how social media networking apps can be used efficiently and effectively to support the antecedents of KS among the employees in public and private universities.

This study is based on a positivistic approach and a quantitative research design. A survey was carried out with employees at public and private universities. The respondents were chosen based on simple random sampling with the purpose of increasing the validity and generalizability of the results in the context of university settings and for other sectors as well.

Certain individual and organizational factors have been found, which have been supported by social networking tools. These factors can enhance KS practices, such as informal relationships and social networking, effective communication and collaboration, mutual trust and the intention to share knowledge, the KS culture and new ideas. The results of this study reveal that social networking applications such as WhatsApp, Viber, Skype, Facebook, Research-gate, YouTube and personal blogs are more productive in supporting the antecedents of KS stated above in university settings.

Social networking applications have received attention because executives and researchers are increasingly focusing on finding new ways to use social networking tools for business purposes. The effective and efficient use of social networking tools helps organizations to foster knowledge amongst employees to address various critical issues, such as knowledge hoarding, lower levels of skills and knowledge, lower levels of communication and employee involvement, a lack of the intention to share knowledge and resistance toward the adoption of new technology.

There is rare literature available on how social networking tools can support the antecedents of KS in university settings. Most of such literature has investigated the link between social media and KS using a systematic literature and qualitative research approach. This research is based on empirical study and it is unique as it investigates the hitherto under-researched issue of the adoption of social networking applications to foster the antecedents of KS in university settings.

Customers are increasingly interested in reading discussions, experiences, recommendations and reviews on social media platforms related to services and products in which they are highly interested. The purpose of this paper is to find the availability of user-generated content (UGC) in the context of Islamic banks and how it can enhance the level of brand engagement and purchase intention of customers.

The methodology for this research is designed by following the features of qualitative research methods and a social constructivism approach. Furthermore, non-directive and semi-structured in-depth interviews are constructed to accumulate research data from marketing teams and customers of Islamic banks. The respondents have been carefully chosen on the basis of purposive sampling and their level of awareness related to Islamic banks.

Islamic banks are more frequently using traditional marketing tools that are unable to enhance levels of information among the targeted population and prove an expensive way of marketing. The findings reveal that Islamic banks lag behind in adopting the latest information exchanging technologies compared to conventional banking systems. A lack of skilled people, reputation and trust, lack of e-marketing strategy and lower levels of investment in social media platforms are major barriers to generate UGC, brand engagement and purchase intention among the targeted market of Islamic banks.

The effective and competent use of various social networking platforms can enhance UGC related to Islamic banking products and services. UGC can generate interactive communication, services reviews, feedbacks, intention to purchase, social influence, social trust and positive customer perception among the targeted population of Islamic banks. The study has summarized and offered practical recommendations to show how Islamic banks can address challenges and enjoy a high level of profitability compared to conventional banking systems.

The present study uncovered the steps that must be taken by the top management of Islamic banks to enhance levels of awareness, online product reviews and recommendations, e-word of mouth and purchase intentions of the targeted market. The study enhanced understanding regarding how a higher level of investment in social networking platforms, safe and secure banking systems and skilled IT professionals can address the challenges of Islamic banks. Furthermore, these factors can create positive UGC, social influence, social brand engagement and purchase intention of customers in Islamic banks. These primary factors must be considered by Islamic banks to compete with conventional banking products and services.

The purpose of this paper is to unfold the relationship between service quality and level of performance of conventional and Islamic banks. Also, it intends to uncover what are the features of service quality which can raise the level of performance either in conventional banks or Islamic banks. There is rare literature available that focused on comparative study between above stated banking systems based on emerging parameters of SERVQUAL model.

To meet the objectives of this investigation, research data has been from 450 customers who have had accounts and dealings with conventional and Islamic banks in the previous five years. The customers are selected based on cluster sampling from regional offices of conventional and Islamic banks.

The collected data have been analyzed by using confirmatory factor analysis (CFA) technique followed by common method variance (CMV), multiple regression test and independent sample t-test used to examine the parameters of service quality in the context of banks performance. The purpose of CFA is to find the model validity, while multiple regression and t-test is performed in order to examine the influence of service quality parameters on banks performance.

The study used compliance as a one of the emerging and unique dimension of service quality. This dimension is rarely investigated in the context of measuring the level of bank performance of conventional and Islamic banking systems. Findings reveal responsiveness and assurance is the strongest predictor of conventional banking performance. Compliance and reliability has significant and positive impact on the level of performance of Islamic banks. Moreover, the study has practical implications for the top management and stakeholders of conventional and Islamic banks to increase the level of performance by using SERVQUAL model.
