A Constraint on the Anomalous Green's Function

It is shown that the physical constraint of the Anomalous Green's function gives a natural pairing condition. The resulting self-consistency equation is directly related to the BCS gap equation. Both inhomogeneous and homogeneous systems are considered to illustrate the importance of the constraint. Especially we find weak localization correction to the phonon-mediated interaction.Comment: 14 pages, latex, no figure

EU Smart City Lighthouse Projects between Top-Down Strategies and Local Legitimation: The Case of Hamburg

The concept of the smart city has become increasingly popular in recent years and a large number of cities globally follow smart city strategies. By awarding subsidies in the Horizon 2020 programme, the European Union (EU) has taken on an influential role in how smart city projects are conceived and implemented in European municipalities. Using the example of the smart city pilot project mySMARTLife in Hamburg, the purpose of this article is to examine the area of tension between strategically pursuing own objectives and adjustment to external provisions of the EU funding framework. In a qualitative single case study, the article analyses what implications the project mySMARTLife has on urban development practice and local governance arrangements in Hamburg. Examining current literature on smart cities from the perspective of multi-level governance and presenting the current state of research dealing with EU smart city projects, a theoretical framework is developed. The analysis reveals that, due to the EU funding framework, precise project contents are contractually defined at an early stage when local stakeholders have limited involvement in this process. Furthermore, the analysis shows that the EU smart city funding in the project mySMARTLife is more limited to the implementation of individual interventions than to a comprehensive smart city strategy. As a result, this article considers EU-funded smart city initiatives as experimental fields that enable cities to gain experiences that can be incorporated into local strategic development objectives

Platformization of Urban Life

The increasing platformization of urban life needs critical perspectives to examine changing everyday practices and power shifts brought about by the expansion of digital platforms mediating care-services, housing, and mobility. This book addresses new modes of producing urban spaces and societies. It brings both platform researchers and activists from various fields related to critical urban studies and labour activism into dialogue. The contributors engage with the socio-spatial and normative implications of platform-mediated urban everyday life and urban futures, going beyond a rigid techno-dystopian stance in order to include an understanding of platforms as sites of social creativity and exchange

Loyalität in Turbulenzen

Supervision hat sich als Beratungspraxis immer dem beruflichen Handeln von Personen und der Reflexion dessen verpflichtet gefühlt. Einer reinen Lehre anzuhängen, verbietet der Gegenstand. Zu unterschiedlich sind persönliche und institutionell-strukturelle Bedingungen, sowohl der Supersorlnnen als auch der Supervisandlnnen. d. h. aber nicht, dass supervisorisches Handeln wahllos und beliebig ist. Um dem eigenen professionellen Handeln angesichts der gesellschaftlichen Herausforderungen eine Orientierung zu geben, bedatf es neben dem fachlichen und wissenschaftlichen Diskurs der Entwicklung und Bewahrung der Supervisorischen Identität. An vier Aspekten wird die spezifische Supervisorische Herangehensweise zur Identitätsgewinnung innerhalb bestehender Lebens- und Arbeitsbedingungen betrachtet und die Frage der Verbundenheit von Supervision als kritische Loyalität aufgeworfen

Workspaces of Mediation: How Digital Platforms Shape Practices, Spaces and Places of Creative Work

This paper investigates how online platforms co-construct spatialities of fashion design. Advancing the notion of workspaces of mediation, the article interlinks research on the geographies of creative work with debates on digital geography. It demonstrates that humans, online platforms, and spatiality are interrelated and come together in the constitution of everyday spatial encounters and experiences. Applying methods from digital ethnography, in-depth interviews, on/offline participant observations, and an analysis of Instagram accounts were conducted. The article demonstrates that Instagram has become a powerful non-human actor that reconfigures (i) practices, (ii) spaces, and (iii) places of work. With the notion of workspaces of mediation, the paper argues that spaces of work must go beyond concepts of hybrid space and beyond the geotag. Instead, mediated workspaces are constituted as a complex entanglement of online and offline socio-spatial relations and practices.Peer Reviewe
