The article aims to examine the formation of geographical realities in the media by so called world insiders. It highlights the application of two theoretical approaches such as discourse and performance or performativity. It notes that the theoretical connection between the discursive and argumentative level on the one hand and the performative level on the other hand melds verbal and non-verbal geography-making.

The article discusses ways to involve nature and materiality in the discussion of social and cultural scientists or human geographers. It notes the inherence of the revised understanding of physical geography in natural science physical geography resulting from the engagement of double hermeneutics on the doing of earth scientist and physical geographers which they characterize as conversation with the earth. Also cited are means to understand the pivotal traits of the history of geography.

This paper addresses family migration amongst highly-skilled professionals. Drawing on the concept of linked lives, it analyses how the linked lives of parents and children affect integration processes after international migration. The article is based on qualitative interviews with highly-skilled migrants and their accompanying partners in Germany and Great Britain. The analysis illustrates how parents try to reestablish stability and security in their children's lives after migration. It reveals common concerns. However, some of the parent's strategies are location-specific. The results indicate that the parent's efforts for their children's integration also have an effect on their own integration. Given the importance of children in the integration process, the paper suggests paying more attention to the children's perspective in future migration research. [ABSTRACT FROM AUTHOR]

The German energy transition is not only characterized by wide technological changes but also by spatial restructuring. The decentralization of energy supply potentially increases the importance of the regional or local scale. The Anglo-American debate on the Politics of Scale addresses the production and transformation of scale while energy issues have not yet been systematically addressed. This paper combines the theoretical paradigms of scale, rescaling and scalar strategies with empirical examples from the German energy transition. Using the cases of energy regions, remunicipalizations and social movements, the implications of the German energy transition are analyzed regarding the role of scale. The paper argues that the perspective of the Politics of Scale can contribute not only to a better understanding of the different dimensions of energy transitions but also to critical energy geographies in general.

Drawing on Foucault's notion of governmentality and on ethnographic fieldwork in a German city, this paper addresses practices of governing "Muslims" and "Islam" at the level of local politics. It conceptualises these practices as a governing through friendship, that is, a type of "liberal" conduct-of-conduct that focuses on trust-building and practised "togetherness". The paper analyses techniques of governance and processes of subjectivation, putting an emphasis on how emotionality becomes integrated into governmental practices. I show how governing through friendship unfolds in the spatio-political context of a local dialogue with "Islam", how the latter is linked to the interfaith paradigm and thus becomes a religiously-sensitive, post-secular political technology in which religious sensibilities are becoming elements of governmentality.

In the last ten years, several uprising organizations such as the so called "Islamic State" have become a new challenge for civil societies in facing and defeating international terrorism. This paper, as part of a bigger research project, presents theoretical and methodical approaches for analyzing those organizations in the way they operate abroad and how they are connected with foreign fighters, sympathizers and supporters. By using ethnographic tools, we have observed and analyzed 14 "Islamic State"-related criminal proceedings in front of high-secured regional appeal courts. The paper presents the first results of this study in showing how German islamists are using transnational logistic networks to join or support terrorist organizations (Part 1) and gives insight into the way the logics of jurisdiction in democratic societies constitute them as "threatening subjects" (Part 2). In this way, it addresses a new approach of court-based research from the perspective of political geography. [ABSTRACT FROM AUTHOR]

This paper undertakes a creative exploration of bulky rubbish [sperrmüll] in the City of Bonn by expanding on and utilising what has come to be known as non-representational thinking. Through a nonrepresentational engagement with sperrmüll, I shed light on waste as a significant human-nonhuman ecology as it appears in an especially routinised manifestation in urban space. In doing so, the paper contributes to a discussion about enacting non-representational methodologies within German-speaking human geography. Here, there are three methodological interventions for a non-representational endeavour: (1) interfering, (2) material thinking, and (3) writing and presentation. These interventions are supported by revisiting Deleuze and Guattari’s notion of assemblage; using it as a way to attend to sperrmüll as an area-sized fabrication connecting humans and various other materialities, and which directs thought towards a wide array of agencies. In conclusion, nonrepresentational perspectives are advanced as a way to expose the affective ecologies that enable certain actions and hamper others. [ABSTRACT FROM AUTHOR]

"Religious spaces" can become a powerful nucleus of (geo-) political imaginations, identities, and conflicts. The paper outlines this aspect using the example of Tibet. Considering the prominent position of Buddhism in Tibet, the tense relationships between religion, space and nation come into view. In this respect the paper does however not primarily discuss the quite well known antagonistic constructions of pro-Chinese and pro-Tibetan geopolitical discourses. Rather, it addresses the far less publicized yet for the development of Tibetan Nationalism equally important fact that differences in the production of religious spaces and respective identities can also be found within Tibetan society. Tracing these discursive inventions of tradition helps to better understand, why the establishment of a national project in Tibet has been difficult and why it only started to gain traction and visibility in the face of mounting threads by an antagonistic exterior and the precarious Tibetan exile situation.

The micro-macro-problem of the social sciences is also present in human geographies' discussions of creativity. Creativity could be conceptualized either as a capability of subjects or as emerging from interaction processes. A direct consequence of this theoretical indecision is an inconsistent notion of creativity in Nigel Thrifts' nonrepresentational theory (NRT) that is originally developed to valuate creative praxis. The paper advances a proposal for conceptualizing creativity in NRT by using the philosophy of symbolic forms established by Ernst Cassirer. First, the paper develops a notion of individual creativity that is implied in Cassirers' work on symbolic pregnance and symbolic forms and via Bourdieus' interpretation of Cassirer also in the French sociologists' theory of incorporation. Second, the paper shows two possibilities to include the outlined notion of individual creativity in NRT. Creativity could be linked with NRT by modifying Bourdieus' concept of incorporation as used to establish a notion of nonrepresentational praxis. The second possibility of including creativity is a connection of affect and experience, which leads directly to the emergence of novelty [ABSTRACT FROM AUTHOR]

The paper discusses street vendors' spatial appropriations and the governance of public space in Dhaka, the capital of Bangladesh. The much debated question in social geography how people's position in social space relates to their position in physical space (and vice versa) stands at the centre of the analysis. I use Bourdieu's Theory of Practice to discuss this dialectic relation at two analytical levels. On a micro-political level it is shown that the street vendors' social positions and the informal rules of the street structure their access to public space and thus determine their "spatial profits". At a macro-political level, it is not only the conditions inside the "field of street vending" that matter for the hawkers, but also their relation to the state-controlled "field of power". The paper demonstrates that Bourdieu's key ideas can be linked to current debates about spatial appropriation and informality. Moreover, I argue that Bourdieu's theory builds an appropriate basis for a relational, critical, and reflexive social geography in the Urban South. [ABSTRACT FROM AUTHOR]

Theoretically, the paper draws on conceptualisations of fluid identities and space; methodologically, it is informed by positioning analysis. The case of the delinquent youth clique "FX Fighters" shows that members produce their neighborhood as a challenging space and simultaneously position themselves in this space: sometimes as powerful and fearless youths who dictate rules and keep others in check, sometimes as a youth clique whose vengeance fails. In addition, the paper demonstrates how assaults of violence are legitimated and normalised. In order to show the variance of such legitimating strategies and related subject positionings, material from additional group discussions on violent practices in public space is presented. Finally, the production of subjectivity as part of data construction is reflected. [ABSTRACT FROM AUTHOR]

This short paper provides the initial provocation for a themed issue that emerges from a conference on the topic of geographies of social crises/crises of social geographies. The article calls for a (re)consideration of the "social question" in the 21st century. We call for social geographers to engage with the historical dynamics of places and milieus to understand novel class societies and the violence that underpins social inequalities. The article makes a case for an empirically saturated social geography. We believe this provides a useful programme which helps to understand current phenomena of political, social and economic crises. [ABSTRACT FROM AUTHOR]

Publications from the early quantitative revolution in geography saw a significant change in the use of visual material. While the old regionalist paradigm of "Länderkunde" was dominated by images of "geographical individuals" the new geography was dominated by abstract models and visualized laws and theories. Overall visual material gains in importance, both quantitatively and qualitatively. This paper follows the changed functions, possibilities and promises of visualizing epistemic things in geography's new paradigm. This is done by following the translations, transformations and mobilizations of the famous hexagon Walter Christaller published in his 1933 "Theory of central places in South Germany". Since the 1940s this Hexagon has become not only an icon of the new geography, but an instrument for making quantitative-theoretical thinking in the geography plausible and at the same time to build a visual bridge between the old and the new geography.

While the role of materiality was understudied in most social sciences, there was a sensibility for these issues in political ecology. The different approaches of political ecology focused on the political character of ecology and the ecological (and thus material) character of politics. But a conceptual framework that captures the different dimensions of the societal nature relations was seldom explicitly elaborated. Following the considerations of Michel Foucault, this article explores whether dispositive analysis as a concept and as a method offers a way to integrate both social and material conditions into studies of political ecology. By examining water infrastructure and the dispositive of drought in Northeastern Brazil, this paper displays how dispositive analysis is a means to identify different elements, their autonomies as well as their interconnectedness. Focusing on the entanglements of discourses, institutionalizations, subjectivity, practices and materiality allows capturing the materiality of discourses and the discursivity of material orders.

Questions about how human-environment-relations can be conceptualized in a non-dualistic way have been intensively discussed throughout the last decades. The majority of the established realist and constructivist perspectives aim at explaining a given situation by analytically dissecting it. Unfortunately, such an interactionist perspective systematically reproduces the dualistic division between humans, environment and nature. In contrast, this paper offers a transactive perspective origin in classical pragmatism and discusses its metatheoretical consequences for human-environment-research. A transactionist perspective interprets the world as a flow of unique and entangled events. Instead of ontologically separating humans and environment, it advocates to look at their relations as being part of a "connatural world". Such a point of view raises new ethical and political questions for geographical human-environment research, argues for a renaissance of ideographic methodologies and hints to a fruitful unity of geographical inquiry.

This paper draws on my books Urban Outcasts and Punishing the Poor, on the transformation of the forms and policy management of marginality in advanced society, to probe the use of space as a medium for social closure and control in the city. This first part sketches a framework for the (comparative) analysis of sociospatial seclusion, the process whereby particular social categories and activities are corralled and isolated in a reserved and restricted quadrant of physical and social space. The second part applies this schema to present a compressed analysis of the divergent trajectories of the black American ghetto and the French working-class borough in the post-Fordist age anchored by the three spatially inflected concepts of ghetto, hyperghetto and anti-ghetto. It concludes by stressing the role of the state in directing processes of seclusion at the top and at the bottom of the urban order, along a gradient from constraint to choice.

Within the academic field of Geography, there is an "identity crisis" facing German-language scholarship in Development Studies programs, particularly in terms of disciplinary characteristics, epistemological aims and methodological approaches. This critical self-reflection finds its expression in the use of terms like "mid-range theory" or "global south", and is manifest as well in repeated calls for a re-formulation of the discipline. Simultaneously, an increasing number of empirical studies in this field are informed by readings of Bourdieu, and are relying on praxeological and corresponding relational perspectives. These studies are transcending the prevalent actor-centered paradigms. Against such a background this paper not only shows how Bourdieu's suggestions can contribute to countering conceptual and discursive dichotomies, regionalized exoticism of cultural contexts and a normative bias (especially in applied research), but also indicates directions for a reformulation or alternative interpretation of the discipline. In order to address these issues, we focus on the key concept of relationality, which is epistemologically central to understanding the "social world"; academically central for a praxeological concept of global social research; and methodologically central in terms of self-reflexivity and a heuristic approach to social categories.
