Abstract

Purpose

The purpose of this paper is to investigate the simultaneous effects of ionization and dispersion of soil on the impulse behavior of grounding electrodes under first and subsequent stroke currents.

Design/methodology/approach

A recently introduced technique called improved multi-conductor transmission line (MTL) is simplified for grounding electrodes buried in both-affected soils.

Findings

The simulation results show that including the two effects simultaneously in highly resistive soils under high-valued subsequent stroke current is recommended. Otherwise, simultaneous effects can be disregard.

Originality/value

To the best of the authors’ knowledge, there is no research on sensitivity analyses for the simultaneous inclusion of the two effects on the effective length and the induced voltage on the soil surface. To this end, the simplified MTL is applied to the grounding electrodes. The simulation results show that the computational efficiency in comparison with previous methods is, first, considerably increased. Second, the simultaneous effects result in decreasing the soil surface voltage with respect to situations where either ionization or dispersion is taken into account (single-affected soils). In other words, the performance of grounding systems is improved. Third, the effective length in both-affected soil is has a middle value with respect to the single-affected soil. Such findings practically and financially are of importance.

Abstract

Purpose

Strategic entrepreneurship rejuvenates firms to achieve a competitive advantage in current markets. It is effective in forming corporate entrepreneurship and involves the simultaneous opportunity-seeking and advantage-seeking behaviors of firms. The aim of this paper is to investigate the mediating effect of strategic entrepreneurship in the relationship between corporate entrepreneurship and firm performance through the resource-based view.

Design/methodology/approach

Adopting a quantitative research method and structural equation modeling technique, structural models were developed to test the research hypotheses. To this end, a questionnaire survey was conducted among 103 financial technology companies in Iran.

Findings

The results support the proposed hypotheses. The findings indicate that corporate entrepreneurship and strategic entrepreneurship are positively related to firm performance. They also reveal the mediating effect of strategic entrepreneurship in the relationship between corporate entrepreneurship and firm performance. In the developing context of Iran, financial technology companies are more likely to employ corporate entrepreneurship and strategic entrepreneurship to achieve firm performance.

Originality/value

The current study contributes to the literature on strategic entrepreneurship by employing a resource-based view and exploring the relationship between firm capabilities (i.e. strategic entrepreneurship) and firm performance. Applying a resource-based view leads to a better understanding of strategic entrepreneurship. Finally, this study singles out and discusses the various features that characterize the implementation of strategic entrepreneurship by Iranian financial technology companies to reach a competitive advantage.

Abstract

Purpose

Today, urban entrepreneurship is considered one of the vital strategies that directed cities toward self-control by reducing the unemployment rate and its arising problems, creating sustainable revenue and preparing the ground for citizens’ independence. This paper aims to present an integrated foresight framework and establish the boundary conditions for urban entrepreneurship of women breadwinners. The study explains how particular women solve workplace-specific poverty and foster urban wealth by developing startups, new businesses or ventures.

Design/methodology/approach

The current research uses a qualitative method and uses the grounded theory approach. Data were collected by selecting 24 outstanding women entrepreneurs using snowball sampling and semi-structured interviews in Tehran Metropolitan.

Findings

The results of the study reveal that the main aspects of the model of urban entrepreneurship consist of causal factors, intervening factors and contextual conditions. By shaping the policies and organizing educational plans, training courses and empowering of women, as well as the establishment of supportive units for the development, identification of the opportunities, developing protective rules, the factors as mentioned above lead to cultural, social and economic development, tendency toward entrepreneurship and development of entrepreneurship among women.

Originality/value

This study undertakes a first of its kind cross-disciplinary conceptual analysis at the level of how women breadwinners foster urban wealth using developing new businesses, startups or ventures. Despite the importance of urban entrepreneurship, theories for understanding the nexus of urban contexts remain underdeveloped. Therefore, there is still a theoretical gap and lack of research; hence, the current study tries to shed light on the topic and fill this gap in the body of knowledge.

Abstract

Purpose

Tall towers have a high potential for being struck by lightning which is a major source of electromagnetic radiation with adverse effects on electric, electronic and telecommunication instruments. The paper aims to present an accurate method for predicting the radiated electromagnetic fields and current distribution along the lightning channel and the tower hit by the lightning.

Design/methodology/approach

The electromagnetic model is utilized to model the lightning channel and the tower is represented by lossy conducting wires. The finite difference time domain (FDTD) method is used to solve for the governing Maxwell’s equations. Due to the large computational space, the FDTD code is paralleled between several computer processors. To enhance the efficiency of the code, a non-uniform mesh is used, reducing the mesh length in the air-ground interface. For model evaluation, simulated current distribution along the lightning channel and tower, and the radiated electromagnetic fields are compared with the measurement data and those obtained using the engineering models.

Findings

The proposed modeling technique has proved to be more accurate than the conventional methods, particularly in the prediction of current distribution along the tall tower and the vertical component of the radiated electric field.

Originality/value

The main feature of the proposed technique is its ability to consider the impact of metallic structures in a large space around lightning channel on the predicted radiated electromagnetic fields, having no concern on computer memory requirements.

Abstract

Purpose

The purpose of this paper is to improve the quality and efficacy of data collected from Muslim respondents, particularly women, through an examination of Islamic teachings and illustrated using a “conservative” paradigm of practice. The paper is designed to be helpful to researchers in designing both their projects and their data collection methods.

Design/methodology/approach

The paper is conceptual, in that it provides an overview of some important, often overlooked or misunderstood areas on which studies have been based and gives frameworks and also ethical pointers to researchers.

Findings

Framed to explain approaches to “conservative” Muslim women in societies across the globe, what is presented herein allows insight into all varieties of Muslim practice. This is achieved by explaining the possible objections to different methodologies and techniques of research for Muslim women at the “conservative” end of the practicing spectrum – this allowing a highlighting of ideas and ideals applicable across the spectrum.

Practical implications

Useful for academic researchers and also commercial researchers, potentially saving both time and money by pointing out possible errors in research design while also ensuring good ethical practice. The paper is offered to assist researchers in eliciting full and frank responses from Muslim respondents based on informed and thoughtful research design and data collection and providing possibly contextualisation(s) of what is said to enhance data analysis and interpretation.

Originality/value

Believed to be the first paper of its kind in English, this conceptual paper provides insight for researchers aiming to get the most useful and ethically sound outcomes for those interviewed, as well as those interviewing.

Abstract

Purpose

In recent years, and especially during the coronavirus disease 2019 (COVID-19) pandemic, the significant role of agriculture, specifically red meat, in household consumption has been increased. On the other hand, the lack of proper policymaking in the production and pricing of red meat and the lack of a comprehensive study on the beef supply chain has led to a reduction in the role of this protein product in the household food basket. Thus, in this research, comprehensive strategic planning considering the effect of the COVID-19 pandemic has been illustrated to overcome the aforementioned problems.

Design/methodology/approach

To study the intended objectives, first, using qualitative methods, the strengths, weaknesses, opportunities and threats (SWOT) to the studied company's supply chain in Iran were identified and then using the SWOT-Quantitative Strategic Planning Matrix (QSPM) technique, the surrounding strategies have been analysed.

Findings

The results indicate that the most important strength of the studied company is the “access to the red meat market of the retirement plan”; the most important weakness is the “lack of required and on-time funding, especially in the condition of the COVID-19 pandemic”; the highest-ranked opportunity is the “access to banking facilities” and the main threat to the company is the “COVID-19 pandemic limitations and health protocols”. In the same vein, by examining the attractiveness score of internal and external factors, it was observed that diversity and competitive strategies would have a higher priority. Finally, the QSPM illustrated that activating the full capacity of existing infrastructure has the highest priority.

Originality/value

According to the red meat supply chain and the link amongst different market levels, identifying, analysing and improving the beef supply chain is of particular importance. One of the threats facing the international community is the emergence of events such as the COVID-19 pandemic, which requires businesses to choose the right strategy to deal with the issue. Therefore, the main distinction of this study is to identify, analyse and improve the red meat supply chain of a real case due to the condition of the COVID-19 pandemic.

Abstract

Purpose

Several variables can affect work stress. This study aims to model the cause-and-effect relationships among different variables that can predict work stress based on one of the most important fuzzy multicriteria decision-making methods used to investigate the cause-and-effect relationships among variables.

Design/methodology/approach

This study was conducted in 2020, including 17 experts in safety management, occupational health and work psychology, based on the fuzzy decision-making trial and evaluation laboratory method as a robust approach to identify the cause-and-effect relationships among different variables.

Findings

Shift work, lack of job satisfaction, mental health, mental overload, fatigue, job security, sleep disorders, environmental discomfort, work pressure, job knowledge (this could mean expertise/level of qualifications/familiarity with the job), work complexity and role conflict were found to be the most significant variables affecting work stress. Moreover, the cause-and-effect model of relationships among variables showed that shift work and lack of job satisfaction are root causes, and mental health, fatigue, mental workload, sleep disorder and environmental discomfort are direct causes.

Originality/value

Although the results of this study demonstrate that work stress can be influenced by 12 different variables, the modeling results show that some variables, such as shift work and lack of job satisfaction, can directly or indirectly impact other variables and thus result in work stress.

Abstract

In recent years, decision-making regarding business growth has attracted the attention of many researchers. Also, considering the importance of scale in startups for their survival and the development of economies, investigating the scalability of startups in emerging markets that are booming, can be useful. Scaling for international business has taken on a new meaning: they must be leaders in both emerging as well as advanced markets; they must be responsive to customers in both departments, which require tremendous innovation and agility; they have to build the competency needed in designing, developing, and marketing the opposite for advanced world markets; and they need to demonstrate rapid decision-making, innovation, and opportunism in delivery to the cost-sensitive underdeveloped markets. As a result, decision-making about the scale of start-ups at the international level plays an important role. The internationalisation of start-up activities is an extremely important and attractive topic among researchers, entrepreneurs, and practitioners. But there is very little research and also projects on the internationalisation of start-up venture activities, particularly after the gain of scaling and exponential growth.
