Abstract

Purpose

The purpose of this paper is to examine empirically the effect of transformational leadership on followers’ inventiveness and organizational innovation. It studies transformational leadership and innovation at the organizational level and creativity at the individual level.

Design/methodology/approach

A theoretical model was created, which entailed the development of variables and hypotheses. A survey instrument was used to obtain data, through a self-completion questionnaire. The final sample was made up of 503 individuals, recruited using a random sampling technique.

Findings

The results showed that transformational leadership has a significant positive relationship with both followers’ creativity and organizational innovation. Furthermore, a significant positive relationship was found between followers’ creativity and organizational innovation. In addition, the relationship between transformational leadership and followers’ creativity, through the mediating role of employees’ psychological empowerment, support for innovation, workplace relationships and employee learning, was also found to be both positive and significant. However, the data showed that intrinsic motivation does not significantly affect the relationship between transformational leadership and creativity.

Practical implications

The study provides guidance to organizations that need to change their leadership style and approach, as well as their innovation and creativity mechanisms, at a strategic level. The resulting guidance provides organizations with insight into how they can improve the creativity of their employees through motivating, supporting and inspiring them.

Originality/value

This study is an attempt to illustrate the extent to which transformational leadership can affect organizational innovation in Saudi Arabia, specifically in the public sector, and to explore how employees’ creativity can be improved. This research is beneficial for academics, organizations and policy makers, especially in the Gulf countries.

Abstract

Purpose

Information security of an organization is influenced by the deployed policy and procedures. Information security policy reflects the organization’s attitude to the protection of its information assets. The purpose of this paper is to investigate the status of the information security policy at a subset of Saudi’s organizations by understanding the perceptions of their information technology’s employees.

Design/methodology/approach

A descriptive and statistical approach has been used to describe the collected data and characteristics of the IT employees and managers to understand the information security policy at the surveyed organizations. The author believes that understanding the IT employees’ views gives a better understanding of the organization’s status of information security policy.

Findings

It has been found that most of the surveyed organizations have established information security policy and deployed fair technology; however, many of such policies are not enforced and publicized effectively and efficiently which degraded the deployed technology for such protection. In addition, the clarity and the comprehensibility of such policies are questionable as indicated by most of the IT employees’ responses. A comparison with similar studies at Middle Eastern and European countries has shown similar findings and shares the same concerns.

Originality/value

The findings of this research suggest that the Saudi Communications and Information Technology Commission should develop a national framework for information security to guide the governmental and non-governmental organizations as well as the information security practitioners on the good information security practices in terms of policy and procedures to help the organizations to avoid any vulnerability that may lead to violations on the security of their information.

Abstract

Purpose

This research seeks to investigate the impact of individual entrepreneurial orientation (IEO) and entrepreneurial exposure on new-venture gestation activities during COVID-19 pandemic.

Design/methodology/approach

This paper adopted negative binomial regression (NBR) modeling with a sample of Saudi female nascent student entrepreneurs (N = 1,032).

Findings

The research found that females' IEO is significantly and positively associated with how much progress they make in term of the number of activities they carried out in the new-venture gestation stage. Similarly, females who had high entrepreneurial exposure are more likely to commit to many activities and progress in the new venture. Therefore, those who have entrepreneurial experience perform better different new-venture gestation activities during the COVID-19 pandemic than those who have little or no experience.

Originality/value

Over a transformation of demographic variables and using NBR, this paper is the first paper in Saudi Arabia that develops and tests a theoretically based model linking the perceptual entrepreneurial orientation of nascent student entrepreneurs with objectives variables to the progress of new-venture gestation activities.

Abstract

Purpose

This research examines the relationship between the green version of intellectual capital (IC) (measured through green versions of human, structural and relational capitals (GHC, GSC and GRC)), co-creational capital (CC), green innovation (GI), technological innovation (TI) (measured through artificial intelligence) and start-up competitive advantage (SCA).

Design/methodology/approach

An online questionnaire collected data from 275 participants. To test the hypotheses, the data were analyzed using SmartPLS.

Findings

The results confirmed the positive influence of GSC and CC on TI and GI, GRC with GI and that of GI and TI with SCA. The results also reveal that IC can influence innovation and describe how innovation can drive the competitive advantage (CA) of start-ups.

Research limitations/implications

This self-report study examines the associations by collecting data at one point in time, which results in methodological limitations regarding the generalization of the results. The second limitation is that the findings are limited to start-ups.

Originality/value

This research work examined a model that combined three components of green IC, customer capital, two forms of innovation and CA. These associations have not been previously examined yet can provide useful insight into what drives green and TIs and how they further influence competitiveness. This study provides unique inferences that improve the value of the literature on IC and innovation, using start-ups as context.

Abstract

Purpose

The aim of this study is to offer valuable insights to businesses and facilitate better understanding on transformer-based models (TBMs), which are among the widely employed generative artificial intelligence (GAI) models, garnering substantial attention due to their ability to process and generate complex data.

Design/methodology/approach

Existing studies on TBMs tend to be limited in scope, either focusing on specific fields or being highly technical. To bridge this gap, this study conducts robust bibliometric analysis to explore the trends across journals, authors, affiliations, countries and research trajectories using science mapping techniques – co-citation, co-words and strategic diagram analysis.

Findings

Identified research gaps encompass the evolution of new closed and open-source TBMs; limited exploration across industries like education and disciplines like marketing; a lack of in-depth exploration on TBMs' adoption in the health sector; scarcity of research on TBMs' ethical considerations and potential TBMs' performance research in diverse applications, like image processing.

Originality/value

The study offers an updated TBMs landscape and proposes a theoretical framework for TBMs' adoption in organizations. Implications for managers and researchers along with suggested research questions to guide future investigations are provided.

Abstract

Purpose

This paper aims to address the magnetohydrodynamic boundary layer flow of hybrid mixture across a stretching surface under the influence of electric field.

Design/methodology/approach

The local similarity transformations are implemented to reformulate the governing partial differential equations into coupled non-linear ordinary differential equations of higher order. The numerical solutions are obtained for the simplified governing equations with the aid of finite difference technique.

Findings

The velocity, temperature and entropy generation are examined thoroughly for the effects of different budding parameters related to present analysis by means of graphs. It is obtained that owing to the effect of magnetic field along with slip factor, the fluid motion slowdown. However, the flow velocity enhances for the rising estimations of an electric field which tends to resolve sticky effects.

Originality/value

The three-dimensional plots are drawn to understand the nature of physical quantities. To ensure the precision, the obtained solutions are compared with the existing one for certain specific conditions. A good concurrence is observed between the proposed results and previously recorded outcomes.

Abstract

Purpose

Cross-layer approach in media access control (MAC) layer will address interference and jamming problems. Hybrid distributed MAC can be used for simultaneous voice, data transmissions in wireless sensor network (WSN) and Internet of Things (IoT) applications. Choosing the correct objective function in Nash equilibrium for game theory will address fairness index and resource allocation to the nodes. Game theory optimization for distributed may increase the network performance. The purpose of this study is to survey the various operations that can be carried out using distributive and adaptive MAC protocol. Hill climbing distributed MAC does not need a central coordination system and location-based transmission with neighbor awareness reduces transmission power.

Design/methodology/approach

Distributed MAC in wireless networks is used to address the challenges like network lifetime, reduced energy consumption and for improving delay performance. In this paper, a survey is made on various cooperative communications in MAC protocols, optimization techniques used to improve MAC performance in various applications and mathematical approaches involved in game theory optimization for MAC protocol.

Findings

Spatial reuse of channel improved by 3%–29%, and multichannel improves throughput by 8% using distributed MAC protocol. Nash equilibrium is found to perform well, which focuses on energy utility in the network by individual players. Fuzzy logic improves channel selection by 17% and secondary users’ involvement by 8%. Cross-layer approach in MAC layer will address interference and jamming problems. Hybrid distributed MAC can be used for simultaneous voice, data transmissions in WSN and IoT applications. Cross-layer and cooperative communication give energy savings of 27% and reduces hop distance by 4.7%. Choosing the correct objective function in Nash equilibrium for game theory will address fairness index and resource allocation to the nodes.

Research limitations/implications

Other optimization techniques can be applied for WSN to analyze the performance.

Practical implications

Game theory optimization for distributed may increase the network performance. Optimal cuckoo search improves throughput by 90% and reduces delay by 91%. Stochastic approaches detect 80% attacks even in 90% malicious nodes.

Social implications

Channel allocations in centralized or static manner must be based on traffic demands whether dynamic traffic or fluctuated traffic. Usage of multimedia devices also increased which in turn increased the demand for high throughput. Cochannel interference keep on changing or mitigations occur which can be handled by proper resource allocations. Network survival is by efficient usage of valid patis in the network by avoiding transmission failures and time slots’ effective usage.

Originality/value

Literature survey is carried out to find the methods which give better performance.
