Abstract
Purpose
The purpose of this paper is to analyse the eigenforms and eigenfrequencies of stator core stack by experimental and numerical investigation. The influence of material parameters on the structural vibrations is carried out in order to describe the laminated structure of stator core stack with a homogeneous material model.
Design/methodology/approach
The finite element method is applied for a numerical modal analysis. Therefore, a homogeneous transversally isotropic material model is introduced and the influence of each material parameter on the dynamical behavior is investigated. These material parameters are stepwise adjusted to the results from the experimental modal analysis. The investigation includes results from different stator core stacks.
Findings
The influence of material on the modal parameters is shown. Furthermore, material parameters are carried out for stator core stacks, which describe the measured dynamical behaviour.
Originality/value
The presented investigations show a useable material model and corresponding parameters to the description of the laminated structure of stator core stacks.

Abstract
Purpose
The purpose of this paper is to get a more consistent finite element description for three-dimensional (3D) Timoshenko beam elements. It extends the common description of beam elements by modifying the shape functions and considers the warping of the cross-section due to torsion.
Design/methodology/approach
The paper builds mainly on a finite element description of 3D Timoshenko beam elements. The implementation of high-order shape functions for torsion is done by adding a seventh degree of freedom to the system.
Findings
The results reveal that for some beams, depending on their physical dimensions, the warping of the cross-section has large influence. In comparison to a conventional FE program, the extended finite element description considers the warping and yields more accurate results.
Practical implications
An application of the extended finite element description is done with an implementation of the code in MATLAB. The static and dynamic behavior of a rotor in an electrical machine is investigated.
Originality/value
This paper presents a more consistent finite element description of 3D Timoshenko beam elements considering the warping. A comparison to conventional finite element descriptions is given.

Abstract
Purpose
From the perspective of role identity theory, the purpose of this paper is to explain how an artistic creative entrepreneur has set up and operates a business that incorporates a component of social responsibility into the business model.
Design/methodology/approach
An explanatory case study approach was followed in analysing the case of Alenka Repic, the founder and creative director of the company Kaaita, which operates from Slovenia. Data were collected through documentation and interviews and content analysis was used to analyse the data.
Findings
Kaaita has adopted an innovative and socially responsible business model as an artistic creative enterprise. The case study firstly introduces Kaaita and its innovative business model. Thereafter, it describes and discusses the defining roles of Alenka Repic as an entrepreneur and how these roles have shaped what Kaaita does and how it operates.
Research limitations/implications
This explanatory case study has presented the unique case of an artistic creative social entrepreneur, and the innovative business model that has been adopted. However, because only one case has been presented here, it is recommended that additional case studies be conducted. It is also recommended that additional research be conducted in the area of sustainable business model innovation.
Practical implications
The case illustrates how a more deliberate consideration of their role identity could assist entrepreneurs in aligning their personal values and beliefs with how they create, operate and develop their enterprise. It also serves as a reminder to both scholars and aspiring entrepreneurs that the essence of entrepreneurship is to have the passion and courage to be innovative and disruptive and that educators should focus on cultivating skills that are related to identifying and exploiting opportunities for innovative disruption.
Originality/value
The study draws on role identity theory to gain insight into the roles that are exercised in developing an innovative business model that combines diverse types of entrepreneurship.

Abstract
We consider how the commercialization of social ventures may result from their founders’ personal experiences of commercial organizing. Building on theories of individual imprinting, we theorize that the commercialization of social ventures is influenced by two types of commercial experience: parental imprinting from the commercial work experience of a founder’s parents, and work imprinting from a founder’s professional experience within for-profit organizations. We find support for our theory based on analysis of a novel dataset of over 2,000 nascent social ventures and their founders. We further find that the marginal effects of additional work imprinting from a founder’s commercial experience decline with the longevity of this experience. We discuss implications of our findings for literatures on social ventures, imprinting, and hybrid organizations.

Abstract
Purpose
The underlying assumptions of Baumol’s theory of entrepreneurial allocation limits its potential to answer some key questions related to the entrepreneurship allocation. Hence, this paper aims to highlight the inherent limits of Baumol’s theory and suggest a new approach for understanding the entrepreneur-institution relationship and their functions.
Design/methodology/approach
This is a conceptual paper with a narrow focus on the literature.
Findings
The paper argues that Baumol’s adherence to neoclassic economics assumptions about entrepreneur and institution, such as entrepreneurs as rational choice taker with predetermined goals or institutions as exogenous, limits the potential of his theoretical framework to explain productive entrepreneurship in weak institutional settings. As such, underlying on Austrian economics assumptions about entrepreneur and his/her agency, this paper proposes a reconceptualization of productive entrepreneurship as an outcome of the interaction between entrepreneur and context.
Practical implications
Going beyond Baumol’s main proposition of one-sided influence of institutions on entrepreneurship allocation, this research highlights the influence of individual factors and entrepreneurial action on choosing entrepreneurial paths by entrepreneurs. So, future policies to stimulate productive entrepreneurship should consider these factors and go beyond Baumol’s mere focus on institutional improvement.
Originality/value
Going beyond one-sided influence of institutions on entrepreneurship allocation, this paper suggests an interaction centric approach which considers the role of actors and institutions as the co-creator of each other in the social process and argues that any effort for explaining the entrepreneurship should consider the co-creative nature of the actors and institutions as well as the endogenous nature of institutions. The proposed approach will help expanding entrepreneurship literature through finding answers to some key under-examined questions in the promising research stream of entrepreneurship allocation.

Abstract
Purpose
The purpose of this paper is to understand how social enterprises (SEs) sustain social focus as they shift their legal format from nonprofit to for-profit. The investigation is driven by the understanding that historical persistence of organizational action can influence the sustenance of social focus.
Design/methodology/approach
The paper uses a case study approach and traces the commercialization process of two microfinance organization from India. The data come from interviews and archival documents spanning across the biography of the selected organizations. The constitutive elements of the commercialization process are identified by using the lens of path creation.
Findings
Evidence suggests that the framing of purpose for microfinance as empowerment of women formed the triggering event to path creation. The organizations retained the focus on social goal by adopting a community centered delivery model of self-help groups. The organizational practices adopted after commercialization helped these organization to address the issues of drift actively.
Research limitations/implications
The paper suggests that framing of organizational purpose can play a crucial role in sustaining hybrid character in SEs. It reinforces earlier findings that stakeholders can exert significant influence in balancing social and commercial goal. The aspiration to be identified as a pro-community organization is another critical driver in sustaining social focus. Finally, for SEs to sustain their social focus, proactive engagement with the community should become an integral part of organizational practices.
Originality/value
The paper explores the constitutive elements of path creation and demonstrates the sustenance of social focus through three stages of organizational path development. It also offers insights into the literature on historical imprinting by exploring the internal process through which imprinting is sustained and amplified and by presenting sources and outcome of imprinting.

Abstract
Purpose
This paper aims to make sense of the social enterprise in a frame of social procurement and conceptualise it as a provider of public welfare based on bibliometric material. Comprehensively, it contributes to developments in social procurement, which has received limited attention.
Design/methodology/approach
Scoping literature from Web of Science and using bibliometric methods, the paper identifies and qualitatively explores the literary intersections between social enterprise and social procurement.
Findings
Of the 183 articles, four literary clusters are revealed illustrating scholarly intersections and a detailed exploration of social enterprise as a public provider. The alignment and themes of the clusters further indicate the application of, and role played by, social enterprise in social procurement. Collectively, they reveal the dominance of social enterprise in this dyadic relationship and a minor undertaking of research in social procurement.
Social implications
This “sense-making” groundwork forms a foundational step in developing our understanding of procurements through social enterprises. Furthermore, a positioning and conceptualisation of social enterprise accredits their utility and applicability in delivering public benefits. In this way, the paper informs and supports scholarly and practice-based interest into social enterprises for the delivery of public services.
Originality/value
The paper presents the first bibliometric conceptualisation of social enterprise in relation to social procurement and offers detailed insights through the bibliometric clusters. Furthermore, the paper contributes to the underdeveloped social dimension of procurement and bridges the gap between two distinct fields of scholarship: public management and administration and social entrepreneurship.
