Alternative Capitalism and Creative Economy: the Case of Christiania

The Free Town of Christiania is an autonomous community of about 1,000 inhabitants in the centre of Copenhagen. Built as a squat for a hippy community in the 1970s, it is today a central node in the geography of activism, anarchism and alternative social life. This article analyses Christiania from the specific perspective of creativity and within the context of the ‘creative city’ debate. The Free Town is a lively innovative milieu, nurturing the arts, social experimentation, ideas and original architectural solutions. As such, it is becoming a more and more relevant space from the point of view of the market economy and in the promotion of the idea of a ‘creative Copenhagen’. But I argue that much of its creative potential is connected to place‐specific socioeconomic factors. In this sense, the Christiania experience troubles mainstream conceptions of creativity by revealing that creativity is both fluid and situated.

Swedish tribalism and Tanzanian entrepreneurship: preconditions for trust formation

The aim of this paper is to explore the relationship between entrepreneurship and the structure of the periphery. The objective is to reach an understanding of the entrepreneurial process within the context of the periphery, which is traditionally seen as a poor environment. The paper considers the concept of peripherality and identifies a process of gravitation that drains higher order services towards the core. However, this deterministic model does not correspond with the realities of the Scottish Highlands. The paradox is that new businesses are being created that appear to use old redundant peripheral values such as tradition. It is argued that it is the social construction of the periphery that produces this post-modern change. The qualitative methodology indicates the emergence of a new spatial paradigm of aesthetic consumption. Two indicative case studies are presented which show that entrepreneurship is the creation and extraction of value from the environment. Their businesses are the commodification of non-material and aesthetic values. Further analysis of these data demonstrates that entrepreneurs interpret their own version of the environment, rather than merely reacting to it. In turn, they enact this interpretation which forms the basis of their businesses.     

Urban Informality and the State: Geographical Translations and Conceptual Alliances

Understandings of informality commonly derive from research undertaken in states perceived as lacking the capacity to regulate the practices of their populations. This Interventions forum aims to expand the geographical parameters of empirical research on urban informality. A more global approach, we argue, also necessitates questioning assumptions that undergird this concept—in particular the underlying conception of the state. In this vein, this collection of papers aims to rethink theories of the state through the lens of informality, and vice versa, to inform and refine the concept of informality through a more thorough understanding of states. In so doing, the contributions engage with concepts that have been central both to theories of the state and to the study of informality, namely governance, agency, legitimacy, sovereignty and legality. Following this introduction setting out our theoretical approach, the Interventions forum unites five empirical studies that discuss the nexus of informality and states in contexts that have been researched less extensively from this perspective, each tackling one of the above‐mentioned concepts. Based on these different entry points, the papers provide novel angles on a state‐theoretical understanding of informality. A concluding essay brings these approaches together, reflecting on the possibilities of translating concepts to different sites.

Experiencing a New Place as an Atmosphere: A Focus on Tours of Collaborative Spaces

In this article, we ethnographically explore how tour guides convey different embodied experiences of space and place during tours of collaborative spaces. These tours draw on participants’ embodied experience and emotions in order to reveal the invisible dimensions of everyday activities of collaborative spaces, in particular their different organizational atmospheres. By systematically coding 110 tours of such spaces, we identify four emotional registers – “initiation,” “commodification,” “selection,” and “gamification,” which are used by tour guides to produce a particular atmosphere. We feel that the concept of “atmosphere” is a powerful means of exploring the unbounded and fluid spatiality, the quasi-materiality, and the temporality of the work practices that individuals are likely to experience if they become members of these collaborative spaces. We conclude our analyses by considering the implications of this study for the management of collaborative spaces and new work practices more generally.

Urbanization and the City Image in Lowry at Tate Britain: Towards a Critique of Cultural Cityism

This article explores cultural cityism at a time when a more expansive, ‘planetary’ urbanization is argued to have superseded ‘the city’ as the dominant urban form. It takes an essentially Lefebvrian problematic and works this through an examination of one aspect of contemporary metropolitan culture, the L.S. Lowry exhibition at Tate Britain, held in the summer of 2013. The article scrutinizes the juxtaposition of Lowry's images of the industrial city with the image of ‘global’, corporate London provided by Tate Britain itself. The exhibition is presented as evidence of Lefebvre's argument that although the urban core has imploded and exploded, through images the city ‘can perpetuate itself, survive its conditions’. Taking stock also of the preponderance of city images in culture more widely, it is argued such images make a fetish of the city, producing also an ‘urban pastoral’ that obscures the defining characteristics of urban life today. Finally, Benjamin's concept of the ‘dialectical image’ and Rancière's notion of the ‘sentence image’ are invoked to capture the flashing together of past and present city images and the opportunities for critical reflection this constellation presents.     

Towards a Theory of Serendipity: A Systematic Review and Conceptualization

Serendipity – the notion of making surprising and valuable discoveries – plays a major role in the success of individuals and organizations alike. Previous research has established the importance of serendipity and identified important individual- and organizational-level antecedents. However, the literature has been dispersed and the boundaries of the concept have been blurry, leading to a lack of conceptual clarity and structure, and thus limiting validity and managerial actionability. Based on a systematic literature review, I synthesize existing management-related research on serendipity and explicate the emergence and composition of serendipity in the organizational context. I first identify three necessary conditions that differentiate serendipity from related concepts such as luck or targeted innovation: agency, surprise, and value. Then, I draw from the literature on sensemaking, event-based theorizing, and quantum-based approaches to management to conceptualize the process of cultivating serendipity in the organizational context as a process of enabling potentiality and materialization, and develop a multi-level theory of (cultivating) serendipity. This conceptualization contributes to our collective understanding of how, why, and when (i.e., under what conditions) organizations can leverage the value in the unexpected, which opens up fruitful avenues for further research.
