The present article aims to provide an overview of the consequences of dynamic soil-structure interaction (SSI) on building structures and the available modelling techniques to resolve SSI problems. The role of SSI has been traditionally considered beneficial to the response of structures. However, contemporary studies and evidence from past earthquakes showed detrimental effects of SSI in certain conditions. An overview of the related investigations and findings is presented and discussed in this article. Additionally, the main approaches to evaluate seismic soil-structure interaction problems with the commonly used modelling techniques and computational methods are highlighted. The strength, limitations, and application cases of each model are also discussed and compared. Moreover, the role of SSI in various design codes and global guidelines is summarized. Finally, the advancements and recent findings on the SSI effects on the seismic response of buildings with different structural systems and foundation types are presented. In addition, with the aim of helping new researchers to improve previous findings, the research gaps and future research tendencies in the SSI field are pointed out.
This paper presents initial findings from the empirical analysis of community based social enterprise (SE) and non-profit organisation (NPO) ecosystems in Johannesburg. SEs and NPOs are widely recognised as contributors to the resilience of marginalised urban communities. However, the connection between these organisations , urban governance, and community resilience has not yet been sufficiently understood , particularly in African urban contexts. The 'Resilient Urban Communities' project focuses on Johannesburg as a case study to shed light on this under-researched topic. The key to exploring it is understanding SEs and NPOs as providers of public services, job creators, and promoters of good governance, all of which contribute to community resilience. Using this premise as a starting point, this paper investigates ecosystem conditions with a particular focus on state-civil society partnerships. Empirical data was generated through semi-struc-tured interviews and analysed with a grounded theory approach. Preliminary results of this ongoing research reveal that urban geography is a relevant ecosystem factor for SEs and NPOs from marginalised communities. We also suggest that co-production could be an opportunity for growth within the investigated state-civil society partnership.
Es gibt keine Kreativität ohne Obliteration – also ohne Überschreiben und Entwerten oder Vergessen und Vernichten. Johannes Bennke setzt erstmals die Obliteration ins Zentrum der Medienphilosophie und deckt im Anschluss an Emmanuel Levinas in ihr etwas bildlich Negatives auf. Als Differenzfigur erlangt die Obliteration gestalterische Sprengkraft sowie ethische und epistemologische Relevanz. Über Bildkonjunktionen als genuine Methode der Bildwissenschaft entsteht so eine Theorie der Kunst und eine Philosophie des Medialen nach Levinas, die sedimentierte Wissensformen erschüttert und im Zeichen eines Lebens mit Anderen erneuert.
Die Planungsforschung hat sich spätestens seit der „kommunikativen Wende“ intensiv damit beschäftigt, wie mit Konflikten umgegangen werden soll und wird. Ansätze der „agonistischen“ Planungstheorie widersprechen der normativen Prämisse, Konsensbildung unter den Planungsbeteiligten anzustreben. Vielmehr wollen sie widerstreitende Positionen normativ für die räumliche Entwicklung fruchtbar machen. Zugleich betonen sie eine vermeintliche Dualität von Planung und Protest, die in der neueren Protesttheorie infrage gestellt wird. Dieser Beitrag zeigt aufbauend auf einer Diskussion von planungs- und protesttheoretischen Ansätzen und einer empirischen Analyse planungsbezogener Proteste in Deutschland, dass diese Proteste von den Planungsakteuren zwar immer stärker als „Normalität“ aufgefasst werden und antagonistische Partizipation trotz zunehmender Konflikthaftigkeit und vermeintlicher Infragestellung der repräsentativen Demokratie kulturell regelgebunden bleibt. Protesthandeln ist Teil ausdifferenzierter „Partizipationsbündel“, die situationsbezogen auch Teilnahme an Beteiligungsverfahren, direktdemokratische Verfahren und Klagen umfassen. Protestierende verfolgen dabei meist eine eher reformorientierte Agenda, die keiner „Zähmung“ bedarf. Allerdings können die zugrunde liegenden Konflikte häufig gar nicht „gelöst“ werden. Planenden hingegen können auch innerhalb eines agonistischen Planungsumfelds rationalistische und deliberative Ansätze zur Verfügung stehen, die sie situationsbezogen und strategisch nutzen.
Beyond metropolitan areas, many peripheral regions and their cities in Europe have, in manifold ways, been significantly shaped by industrialisation. In the context of the relocation of industrial production to other countries over the last decades, the question has been raised as to the role this heritage can play in futural regional development as well as the potential local identification with this history. Hence, this article seeks to analyse the perception of the industrial heritage in the Vogtland region, located alongside the border of three German federal states and the Czech Republic. It inquires as to the perception of the industrial heritage by the local population and related potential future narrations. Based on spontaneous and explorative interviews with local people as an empirical base, a discrepancy between the perception of the tangible and intangible dimensions of the industrial heritage can be observed. On the one hand, the tangible heritage like older factories and production complexes are seen as a functional legacy and an “eyesore” narrative is attributed to them. On the other hand, people often reference the personal and familial connection to the industry and highlight its importance for the historical development and the wealth of the region. But these positive associations are mainly limited to the intangible dimension and are disconnected from the material artefacts of industrial production.

This paper addresses the scope for action by municipalities in a climate emergency and places it in the framework of ecomodern (urban) policy. We analyse the way in which two German ‘climate emergency municipalities’ translate conflicts of post-fossil transformation into concrete political and planning strategies. Although more than 2,200 authorities around the world have already declared a climate emergency, research on the impact of these resolutions on the political orientation of municipalities is very limited. Our research focus is on the (potentially agonistic) treatment of conflicts in planning. We argue that in times of a socio-ecological crisis, success in conflict resolution cannot refer to appeasement and depoliticisation. Instead, we propose a framework of five criteria, based on critical theory on ecomodern strategies, planning processes and degrowth. Thus, this practice-related and explorative paper connects empirical insights from the German cities of Constance and Berlin with an innovative normative framework. The findings tell a complex story of an, at least partial, admission of the failure of previous climate mitigation strategies, a lack of social institutions of limits, an instrumental relation to nature and a disregard for social injustices. The paper discusses how municipalities, in the context of ongoing tensions over the post-fossil transformation in Germany, on the one hand hold on to business-as-usual approaches, but on the other hand also set political impulses for change.
Anti-Gewalttrainings, Gewaltwissen und die institutionelle Erzeugung gewaltbefreiter Subjekte
(2023)
Dieser Beitrag fragt danach, wie Wissen über Gewalt in Anti-Gewalttrainings produziert, vermittelt und sozial wirkmächtig wird. Auf Basis des kommunikativen Konstruktivismus werden diese Kurse als gewaltbezogene Institutionen begriffen, in denen eine Wissensordnung der Gewalt stabilisiert wird. Sie sollen Abweichungen von institutionalisierten Wirklichkeitsvorstellungen in Bezug auf Gewalt entgegenwirken. Dabei lassen sie sich als Selbsttechniken begreifen, durch welche die Kursteilnehmer*innen eine spezifische Subjektposition einüben, nämlich die des gewaltbefreiten Subjekts. Vor diesem Hintergrund wird anschließend zwischen konditionalen und konzessiven Anti-Gewalttrainings unterschieden. Erstere wenden sich an Personen, die tatsächlich von der institutionalisierten Wirklichkeitsvorstellung abgewichen sind und somit gesellschaftlich als Gewalttäter*innen eingestuft werden, während Letztere auf eine Klientel zielen, die potenziell von den gängigen Normen abweichen könnte, obwohl noch keine Gewalt aufgetreten sein muss. Abschließend wird gezeigt, dass den Kursleiter*innen eine wichtige Rolle im Subjektivierungsprozess und der Wissenskommunikation über Gewalt zukommt. Neben Wissen über Gewalt werden durch sie auch Wertbindungen, Legitimationen und Weltbilder vermittelt.
Patterns of Detachment: Spatial Transformations of the Phosphate Industry in el-Quseir, Egypt
(2023)
The establishment of phosphate mines and processing plants by Italian entrepreneurs in el-Quseir in 1912 revitalized a town that had faced a steady decline after the opening of the Suez Canal and re-linked it to the world economy. To this day, the now defunct industrial site occupies a large section of physical el-Quseir and plays a key role in its identity. In this article, we explore the impact of the company’s successive industrialization and deindustrialization based on archival research, interviews, and mapping. By tracing physical changes on-site and in the city of el-Quseir from the founding of its phosphate industry until today, as well as the historical and current interactions of citizens with the industrial facilities, we hope to better understand the “cluster value” of the industrial plant in quotidian life and the effect of the vacuum left behind after the termination of production. As machinery and buildings are slowly eroding in the absence of expressed interest by the former Italian and current Egyptian owners, we aim to discuss the relationship between the citizens and their el-Quseir phosphate plant as a crucial element of its heritage value at the local level.
The most fundamental understating of hybridization methodology takes the form of stable but dynamic notions, accumulated over time in the memory of individuals. Schematized and abstracted, the hybrids representation needs to be reproduced and reused in order to reconstruct and bring back other memories. Reinvented, or reused hybrids can support getting access to social, traditional, religious understanding of nations. In this manner, they take the form of the messenger / the mediator an innate, equivalent to the use of mental places in the art of memory. We remember mythology in order to remember other things.
From individual memory perspective, or group collective memory, the act of recollection is assumed to be an individual act, biologically based in the brain, but by definition conditioned by social collectives. Following Halbwachs, this thesis does not recognize a dichotomy between individual and collective memory as two different types of remembering. Conversely, the collective is thought of as inherent to individual thought, questioning perspectives that regard individual recollection as isolated from social settings. The individual places himself in relation to the group and makes use of the collective frameworks of thought when he localizes and reconstructs the past, whether in private or in social settings. The frameworks of social relations, of time, and of space are constructs originating in social interaction and distributed in the memory of the group members. The individual has his own perspective on the collective frameworks of the group, and the group’s collective frameworks can be regarded as a common denominator of the individual outlooks on the framework.
In acts of remembering, the individual may actualize the depicted symbols in memory, but he could also employ precepts from the environment. The latter have been referred to as material or external frameworks of memory, suggesting their similar role as catalysts for processes of remembrance such as that of the hybrids in my paintings. It is only with reference to the hybrids, who work as messengers / mediators with a dual nature, that communicate between the past and the present, the internal and external space, that individual memory and group memory is in focus.
The exhibition at the Egyptian museum in Leipzig is my practical method to create a communicative memory, using hybrids as mediators in cultural transimission, as when the act refers to informal and everyday situations in which group members informally search for the past, it takes place in the communicative

memory. As explained in chapter one, the exhibition at the Egyptian museum in Leipzig is an act of remembering in search for the past with support of my paintings, which then can considered as part of the cultural memory.
In addition to the theoretical framework summarized above, I have applied my hypothesis practically in the form of the public exhibition, and shared the methodology with public audience from Cairo / Egypt and Leipzig / German in the form of visual art workshops and open discussions. I have also suggested an analyzed description of the meaning of hybrids in my artwork as mediators and messengers for the purpose of cultural transmission, as well as in relation to other artists’ work and use of a similar concept.
By using my hybrid creatures in my visual artwork, I am creating a bridge, mediators to represent both the past and the present, what we remember of the past, and how we understand the past. It is as explained in chapter two; that the hybridization methodology in terms of double membership represented in different cultures –Cairo / Egypt and Leipzig / Germany- can provide a framework which allows artistic discussions and could be individually interpreted, so individual cultures / individual memory can become transparent without losing their identities and turn into communicative memory. This transmission through the hybridization theoretical approech was explicitly clarified with the support of Krämer’s hypothesis. The practical attempt was examined by creating a relationship between the witness –me as an artist– and the audience –the exhibition visitors–, to cross space and time, not to bridge differences, rather to represent the contrasts transparently.
The Kin-making proposition is adopted by many academics and scholars in modern society and theoretical research; the topic was represented in the roots of the ancient Egyptian mindset and supported theoretically by similar understandings such as Haraway’s definition of kin-making. The practical implementation of kin- making can be observed in many of my artwork and was analyzed visually and artistically in chapter three.
My practical project outcome tested success by using hybrids in my paintings as mediators, it opened a communicative artistic discussion. This methodology gave a possible path of communication through paintings / visual analyses, and offered relativity through image self-interpretation.
