Abstract
Purpose
The purpose of this paper is to develop a novel electromagnetic-based acoustic energy harvester (EH) for the application of wireless autonomous sensors.
Design/methodology/approach
The developed acoustic EH comprises a Helmholtz resonator (HR), a suspension system that consists of a flexible membrane and a permanent magnet, a couple of coils and a coil holder. Furthermore, the HR, used in the harvester, is designed for a specific resonant frequency based on simulation carried out in COMSOL Multiphysics®.
Findings
The developed harvester is tested both in lab under harmonic sound pressure levels (SPLs) and in real environment under random SPLs. In lab, when exposed to 100 dB SPL, the harvester generated a peak power of 212 µW. Furthermore, in real environment in vicinity of electric generator, the harvester produced an output voltage of about 110 mV collectively from its both coils.
Originality/value
In this paper, a novel geometric configuration for electromagnetic-based acoustic EH is proposed. In the developed harvester, two coils are placed in it to achieve enhanced electrical output from it for the first time.

Abstract
Purpose
The purpose of this paper is to explore some key factors that influences ethnic entrepreneur’s decision in starting-up a new business in Aberdeen, Scotland.
Design/methodology/approach
The authors set out to investigate the motives, drivers and attitudes of ethnic minorities in seeking entrepreneurial opportunities. The authors conduct in-depth face-to-face interviews with 25 ethnic entrepreneurs from a variety of nationalities and cultures originating mainly from the Indian subcontinent region. This includes entrepreneurs from India, Bangladesh, Pakistan, Sri Lanka and some others. The motivations varies according to their culture, traditions, religion and other environmental factors influencing on their decision to start-up.
Findings
The results reveal some interesting influential factors that lead to the successful start-up decision. These include a positive mindset, self-efficacy, strong determination, knowing of the market and local business culture and good financial management.
Originality/value
This paper is based on empirical research and new data have been collected specifically for this research. The authors hope the new findings from this research work will enhance the understanding about ethnic minority businesses in the context of Aberdeen, Scotland.

Abstract
Purpose
Previous studies have shown how the nature of businesses and the strategies pursued by their owners are affected by the personality traits of their owners. These personality traits can be formed in the early stages of life due to experiences and the surrounding context, where religion is a particularly important aspect of this context. This study aims to explore how religion affects entrepreneurial activities through the personality traits created.
Design/methodology/approach
This study uses interviews with 43 Muslim entrepreneurs in Scotland to examine the role played by religion. This ensures that the national institutional context is kept consistent but also allows an in-depth examination of relationships, which are likely to be interlinked and recursive.
Findings
The traits created influence the nature of the entrepreneurial activities undertaken with the potential to harm and support the entrepreneurial endeavours. It is the combination of personality traits that are formed which have the greatest effect. As such, it is found that Muslim entrepreneurs display less openness and creativity associated with new ideas, but this does not reflect risk aversion rather hard work in itself is valued, and patience combined with an external locus of control mean entrepreneurial behaviours are not altered to boost poorly performing business activities.
Originality/value
For Muslim entrepreneurs in Scotland, their traits explain why growth may not be a foremost consideration of these entrepreneurs rather they may value hard work and meeting the ideals of formal and informal institutions associated with religion. For those seeking to support minority groups through the promotion of entrepreneurship, either they must seek to overcome these ingrained traits or alter support to complement the different objectives held by Muslim entrepreneurs.

Abstract
This chapter presents research to assess the impact of the recent financial crisis on technology-based small firms (TBSFs) in the United Kingdom based on findings from an extended telephone survey with the owner-managers of 49 young and 51 more mature TBSFs, undertaken in 2010. Even before the onset of the global financial crisis in 2007, it was generally acknowledged that TBSFs faced greater obstacles in accessing finance than conventional SMEs. This is because banks have difficulty assessing the viability of new technology-based business ventures due to information asymmetries, whilst risk capital providers may have difficulty providing appropriate or sufficient funds on terms acceptable to entrepreneurs. Given the recent difficulties that SMEs, in general, have faced in obtaining external finance, we would expect TBSFs to have been particularly adversely affected by the financial crisis. Our evidence showed that TBSFs exhibited a strong demand for external finance between 2007 and 2010, related to their growth ambitions and achievements. They sought finance mainly from banks but also with younger TBSFs seeking business angel finance and more mature TBSFs seeking venture capital finance. However, our evidence indicates that both debt and equity finance became harder to access for TBSFs, particularly for early-stage and more R&D-intensive firms. Where funding was offered, it was often on unacceptable terms with regards to the levels of collateral or equity required. The chapter provides evidence of a growing funding gap and concludes that the ability of TBSFs to contribute to economic recovery is hampered by ongoing problems in obtaining external finance.

Abstract
Purpose
The purpose of this paper is to examine and explore why “Small-Businesses” resist employing outside the immediate family and investigate the employee as an outsider and entrepreneurial resource.
Design/methodology/approach
The authors review the literature on barriers to small-business growth concentrating on key empirical and theoretical studies. The authors use empirical data from the Federation of Small Business in which informants commented on growth and employing outside the family.
Findings
The findings suggest that small business owners adopt a polemical stance, arguing that a barrage of employment regulations deters them from employing outsiders because doing so brings trouble in terms of costs such as insurance, taxes, paperwork, leave (maternity and paternity) entitlement, etc. They argue that employing from inside the family or ones peer group is much cheaper, convenient and less hassle. This ignores the entrepreneurial employee as a potential ingredient of growth and points to a paradox whereby the very values and emotions characterized by fairness of which of “smallness” and “familialness” is composed compound the issues of discrimination central to the debate.
Research limitations/implications
The paper offer important insights for growth issues among small businesses and challenge the contemporary equilibrium in terms of small “family-orientated” business philosophy relating to employment practices. Ideologically, the entrepreneur is an “outsider” fighting the establishment, yet paradoxically, in a small-business context s/he becomes the establishment by employing outsiders. This results in the fairness vs unfairness paradox.
Originality/value
The paper contributes to the existing knowledge and understanding on growth issues among small businesses by illuminating a paradoxical insider vs outsider tension.

Abstract
Purpose
The purpose of this paper is to examine and explain why most small firms remain small. A new conceptual framework – the condition of smallness – is proposed.
Design/methodology/approach
A critical examination of the literature about the nature of being a small firm is first conducted. Employing an inductive analysis of responses from a survey of 2,521 small business owners about employment regulation, the nature and effects of smallness is examined.
Findings
It was found that owners' choice making combines with perceptions about their resources to produce a condition of smallness. The condition of smallness is conceptualised as the circularity perceptions, attitudes and consequent practices that reflect lack of knowledge, time and capability. It is argued that this condition of smallness inhibits growth to create a wicked problem that explains why most small firms don't grow.
Research limitations/implications
This work is largely conceptual, albeit the argument is grounded in, and illustrated by, empirical data. The findings may not be generalisable beyond this paper's data sets, but may be generalisable conceptually.
Originality/value
The focus of much scholarly work has been on growth firms. Yet the typical small firm is excluded so that the issues of smallness are often overlooked. This paper, therefore contributes to understanding why small firms don't grow.

Abstract
Purpose
In this paper, an institutional perspective is used to examine the different kinds of pressures on entrepreneurs manifest in a conflict environment. The purpose of this paper is to investigate how they respond to the conflict and establish legitimacy for their entrepreneurship in the challenging context of the north western areas of Pakistan.
Design/methodology/approach
In this study, a qualitative approach is taken based on semi-structured interviews from 16 different firms in the Swat valley.
Findings
The entrepreneurs undertake different strategies towards dealing with conflict and establishing legitimacy. These strategies are identified and examined in relation to the interactions between entrepreneurial behaviour and institutional pressures.
Research limitations/implications
Qualitative research on a small sample inevitably presents a limitation on the generalisability of this work. Further research could employ quantitative methods to address this issue. One particular location is studied, so future research could be carried out in other countries or regions with similar problems.
Practical implications
The study may have value for policymakers who need to know more about how to support ongoing businesses in difficult regions.
Social implications
Better understanding of the needs of small business may in time contribute to a better business climate in difficult regions.
Originality/value
A new dimension is added to institutional theory through its application in the very uncertain environment between all-out war and ongoing violence, identifying the possibility of weak agency for institutional change. Further, the study contributes to the growing body of literature on entrepreneurship in conflict environments.

Abstract
Purpose
The need to address energy management as a significant innovation in the smart grid is emphasized to enable a more effective penetration of renewable energy to achieve energy savings and CO2 emission reductions. The purpose of this study is to propose a holistic, flexible decision framework for energy management in a smart grid.
Design/methodology/approach
According to the situation actor process−learning action performance (SAP−LAP) model, the variables have been identified after a comprehensive analysis of the literature and consideration of the opinions of domain experts. However, the importance of each SAP−LAP variable is not the same in real practice. Hence, focus on these variables should be given based on their importance, and to measure this importance, an interpretive ranking process based ranking method is used in this study. This helps to allocate proportionate resource to each SAP−LAP variable to make a better decision for the energy management of the smart grid.
Findings
This study ranked five actors based on their priorities for energy management in a smart grid: top management, generator and retailor, consumers, government policy and regulation and technology vendors. Furthermore, actions are also prioritized with respect to performance.
Practical implications
The SAP−LAP model conveys information about the state of energy management in India to actors who may proceed or manage the flow of electricity. Additionally, this study aids in detecting vulnerabilities in the current energy generation, transmission and distribution technique. The synthesis of SAP results in LAP, which assists in recommending improvement actions learned from the current situation, actors and processes.
Originality/value
The SAP−LAP model is a revolutionary approach for examining the current state of energy management in a unified framework that can guide decision-making in conflicting situations, significantly the contradictory nature of India’s renewable energy and power sectors.

Abstract
Purpose
Drawing on social identity theory, the purpose of this paper is to propose and test a conceptual framework of the mechanism of customer response toward corporate social responsibility (CSR) initiatives of Islamic banks.
Design/methodology/approach
A survey was completed by 203 customers of Islamic banks in Bahrain. Structural equation modeling, was used to test the hypotheses.
Findings
Islamic ethics fit partially mediates the relationship between CSR initiatives and consumer-bank identification (CBI) which in turn contributes positively to customer advocacy. These findings emphasize the importance of CSR practices compliance with Islamic ethics principles for customers to identify with and advocate Islamic bank.
Research limitations/implications
Understanding the mechanism of customers’ responses toward CSR initiatives of Islamic banks provides insights into the complexities of Islamic bank customers’ perceptions of CSR initiatives. The successful introduction of a mediating variable, namely, Islamic ethics fit suggests future research opportunities.
Originality/value
Much of the value of the present work is because of the findings regarding the relationship between CSR and customer responses. The originality of this study lies in being the first research examining the mediating role of Islamic ethics fit to the relationship between CSR initiatives and CBI which in turn enhances Islamic banks’ advocacy.
