Abstract

Purpose

The purpose of this paper is to propose a simplified representation of the fire load in computational fluid dynamics (CFD) to represent the effect of large-scale travelling fire and to highlight the relevance of such an approach whilst coupling the CFD results with finite element method (FEM) to evaluate related steel temperatures, comparing the numerical outcomes with experimental measurements.

Design/methodology/approach

This paper presents the setup of the CFD simulations (FDS software), its corresponding assumptions and the calibration via two natural fire tests whilst focusing on gas temperatures and on steel temperatures measured on a central column. For the latter, two methods are presented: one based on EN 1993-1-2 and another linking CFD and FEM (SAFIR® software).

Findings

This paper suggests that such an approach can allow for an acceptable representation of the travelling fire both in terms of fire spread and steel temperatures. The inevitable limitations inherent to the simplifications made during the CFD simulations are also discussed. Regarding steel temperatures, the two methods lead to quite similar results, but with the ones obtained via CFD–FEM coupling are closer to those measured.

Originality/value

This work has revealed that the proposed simplified representation of the fire load appears to be appropriate to evaluate the temperature of steel structural elements within reasonable limits on computational time, making it potentially desirable for practical applications. This paper also presents the first comparisons of FDS–SAFIR® coupling with experimental results, highlighting promising outcomes.

Abstract

The objective of this longitudinal ethnography of a rural small town in Northern Sweden, following the presence and identifying the processes associated with an incoming entrepreneur, was to better understand entrepreneurship in a rural context. The significant shaping of entrepreneurship by context is increasingly recognised, with entrepreneurship in depleted communities being an important part of this research movement. This chapter is positioned at the conjunction of these literatures. The authors have studied this community for 10 years; regularly interviewing the entrepreneur and residents; attending meetings and making observations. The authors found that the entrepreneurial creation of garden provoked a raft of change, such that entrepreneurship reverberated throughout the town. To explain these effects, the authors developed the concept of entrepreneurial energy. Entrepreneurial energy is a vitality produced in and by entrepreneurship. It works, in part, as a role model, holding up examples of what can be done. But much more, the presence of entrepreneurial energy serves to invigorate others. It becomes amplified in new ways of doing, new ways of being, yet calcified in the entrepreneurial actions of others. The authors saw how it unleashed the latent, promoted the possible, to entrepreneurially revive the town.

Abstract

Purpose

The ever present need for the miniaturization of electronic assemblies has driven the size of passive components to as small as the 01005 package size. However, the packaging standards for these components are still under development. The purpose of this work is to report results from experiments designed to establish optimum process parameters, pad sizes and component clearances for the surface mounting of 01005 passive components.

Design/methodology/approach

The experiments were designed using MODDE, an experimental design software tool, and were carried out with both 01005 capacitors and resistors. All the assembled components were examined under microscope and judged according to industrial workmanship standards.

Findings

It was found that a viable solder paste printing process for the assembly of 01005 components can be achieved with a 75 μm thick stencil. Type 5 solder paste achieved a similar printing performance to type 4. Under the experimental conditions used, the optimum pad dimensions for the 01005 capacitors were 210 μm length, 220 μm width, 160 μm separation and for the resistors were 190 μm length, 220 μm width, 160 μm separation. The smallest component clearance to reliably avoid bridging was found to be 100 μm. A high placement force of 3.5 N was found to cause cracking of 01005 resistors.

Originality/value

From this work, a surface mount process for 01005 passive components is established and it is concluded that electronics packaging density can be increased through the assembly of these small components. In the near future, the widespread use of them will definitely facilitate a further reduction in the size of electronic assemblies, especially in handheld and portable devices.

Abstract

Purpose

This essay focuses on the Chinese-Japanese Library of the Harvard-Yenching Institute and examines how the Library collected and transported Chinese rare books to the United States during the 1930 and 1940s. It considers Harvard's rationale for its collection of Chinese books and tensions between Chinese scholars and the Harvard-Yenching Institute leaders and librarians over the purchase and “export” of Chinese books.

Design/methodology/approach

This research is a historical study based on archival research at Harvard-Yenching Institute and the Harvard-Yenching Library, as well as careful readings of published primary and secondary sources.

Findings

By examining the debates that surrounded the ownership of Chinese books, and the historical circumstances that enabled or hindered the cross-national movement of books, this essay uncovers a complex and interwoven historical discourse of academic nationalism, internationalism and imperialism.

Originality/value

Drawing upon the unexamined primary sources and published second sources, this essay uncovers a complex and interwoven historical discourse of academic nationalism, internationalism and imperialism.

Abstract

Purpose

The purpose of this paper is to explain how context shapes what becomes entrepreneurial.

Design/methodology/approach

The paper is part of a longitudinal study over ten years, an ethnographic work including interviews, participating in meetings and shadowing. Texts and voices boiled down to transcripts and notes were sorted in NVivo. The empirical material was presented as a simple, short story, with the aim to question established assumptions and relations. The paper propose context as the unit for analysis, instead of entrepreneurs and outcomes. This opened up the scale from a narrow individualism to a much broader appreciation of the entrepreneurship as shaped by social factors.

Findings

The paper provides insights about how context determines entrepreneurship. It is not simply the context in itself, but the things that are going on in the context. What entrepreneurship does is to connect and thus create a raft of changes. The paper suggests that to depart from context as the unit of analysis will avoid the objectification of entrepreneurship and open up for discussing the becoming of entrepreneurship. The case illustrates how entrepreneurship is an event in a flow of changing circumstances. Entrepreneurship is formed from the context itself, rather than being individual or social; entrepreneurship appears simultaneously to be both. Entrepreneurship can and does exist in multiple states regardless of the observer and the observation.

Originality/value

This paper fulfils an identified need to learn more about how entrepreneurship and context interact. It illustrates how context is more engaged in the entrepreneurial process than entrepreneurship theory acknowledges.

Abstract

Purpose

The purpose of this paper is to develop an understanding of entrepreneurship that can help researchers, policymakers and practitioners develop entrepreneurial responses to the current economic, environmental and socio-spatial crisis.

Design/methodology/approach

The paper adopts a conceptual approach. Hudson’s diagnosis of the current patterns of production is applied to the two dominant streams of theorising on entrepreneurship: the opportunistic discovery view and the resourcefulness view of, for example, effectuation.

Findings

The analysis indicates that the opportunistic discovery view and, to some extent, the resourcefulness view are both inadequate as conceptual platforms for entrepreneurial responses to the economic, environmental and socio-spatial crisis. Instead, an alternative perspective on entrepreneurship is developed: Entrepreneurship as re-sourcing. The perspective emphasises the importance of building regional-level resilience through entrepreneurial activity that sources resources from new places and uses these resources to create multiple forms of value.

Practical implications

The paper draws attention to dysfunctions in the current theorising on entrepreneurship in light of the economic, environmental and socio-spatial crisis. Instead, the authors offer an alternative. In doing so, the paper also points to the difficult trade-offs that exist between, for example, long-term resilience and short-term competitiveness and growth on a regional, as well as firm level.

Originality/value

This paper adds to research by offering an alternative view of entrepreneurship grounded – not in economics – but in economic geography, thus highlighting the importance of productions’ grounding in material reality and the importance of addressing non-economic concerns in our way of thinking about entrepreneurship.

Abstract

Purpose

This study aims to contribute with an extended framework on synergy realisation in acquisitions. The study conceptualises synergy realisation after acquisitions, in interaction with other companies in a business network and that synergy can be the result of both intended and not intended actions.

Design/methodology/approach

The study is based on a company involved in acquisitions, being both the acquirer and the acquired. The data for analysis were collected through semi-structured interviews with managers involved in the described acquisition processes. The semi-structured interviews were guided by overarching themes to cover relevant areas of the described acquisitions.

Findings

This study develops a framework in which synergy is used as a concept in business networks. The framework offers a more dynamic perspective on acquisition processes and extends the view of acquisition performance beyond more financial and company internal aspects of acquisition processes. Further, the findings show that related companies such as customers and suppliers, play important roles in synergy realisation.

Practical implications

From a managerial perspective, the study shows the importance of understanding the underlying forces of integration processes.

Originality/value

The concept of synergy used in this study not only includes the companies integrated in an acquisition but also their business networks. Including the integrated companies and their business networks provides a more dynamic perspective from which to plan and realise synergy.

Abstract

The importance of family firms for the development of capitalism, both past and present, has in recent years become widely recognized. Today there is a fast increasing body of literature about forms of family business and variations in family capitalism. Despite this new interest, few of these studies have made the family itself the focus of enquiry – and how different types of family structures and cultural traditions may influence the strategies and development of the family firm. Such connections are explored by comparing and discussing two cases of family firms and their history, set in Norway and Italy, respectively. It is argued that these two cases may be seen as examples of quite different ‘modes of familism’, with different implications for the running of an economic enterprise. These differences concern, first and foremost, cultural conceptions of gender, forms of inheritance, and the role of marriage in constituting the family firm.

Abstract

Purpose

This study aims to discuss how an online community interacts with a local community during the entrepreneurial process. By having a contextualized view of entrepreneurship, this study acknowledges the social and spatial dynamics of the process.

Design/methodology/approach

The inductive approach used in this study is empirically anchored in the case “the library revolt”. This paper analysed interviews conducted in a selected region in Sweden and followed a netnographic method to capture the social interactions online. By using qualitative modes of inquiry, this study attempts to illuminate the social aspects of the entrepreneurial process.

Findings

This study shows how social media works as a contextual element in entrepreneurship. By presenting interactions between an online community and a rural community, it is shown how entrepreneurial processes in rural areas can be shaped not only through local community relations but also by online interaction. It illustrates how an online context, where actors are located with their own unique set of resources, contributes to rural development. By being a part of an ongoing process of structuration, we can view the actors are gaining access to the resources online, which contributes to the change happening in a local community.

Originality/value

This study adds to the conversation of the role of context in entrepreneurship studies. Rural entrepreneurship largely discusses the local social bonds and actions, while this study includes the online social bonds as a part of the reality in which entrepreneurship is developed.

Abstract

Purpose

The purpose of this article is to explore how agency is distributed between human actors and nonhuman elements in entrepreneurship.

Design/methodology/approach

It is based on an inductive longitudinal case study of a garden in a rural community in northern Sweden. The methodology includes an ethnography of the garden, spanning the course of 16 years, and a careful investigation of the entrepreneurial processes contained within it.

Findings

This article identifies and describes different practices to explain how agency is distributed between human actors and nonhuman elements in the garden's context. Three different practices were identified and discussed, namely “calling”, “resisting”, and “provoking”.

Originality/value

Agency/structure constitutes a longstanding conundrum in entrepreneurship and context. This study contributes to the on-going debate on context in entrepreneurship, and introduces a posthumanist perspective—particularly that of distributed agency—to theorising in entrepreneurship. Rather than focussing on a human (hero)-driven change process, induced through the exploitation of material objects, this novel perspective views entrepreneurship as both a human and a nonhuman venture, occurring through interactions located in particular places and times. Coming from the agency/structure dichotomy, this article reaches out for elements traditionally established on the structure side, distributing them to the agency side of the dichotomy. As such, it contributes to an understanding of the agency of nonhuman elements, and how they direct entrepreneurship in context. This theoretical development prepares entrepreneurship theories to be better able to engage with nonhuman elements and provides example solutions for the ongoing climate crisis.
