This PhD investigation lies at the intersection of Architecture, Textile Design and Interaction Design and speculates about sustainable forms of future living, focussing on bionic principles to create alternative lightweight building structures with textiles and digital fabrication techniques. In an interdisciplinary, practice- based design approach, informed by radical case studies from the 1960s to 80s on soft architectures like Archigram, Buckminster Fuller, Cedric Price, or Yona Friedman and critical theory on new materialism, (D. Haraway 1997, K. Barad 1998, J. Bennett 2007) sociological, philosophical (B. Latour 2005, G.Deleuze F., Guattari F 1987) and phenomenological thinkers (L. Malafouris 2005, J.Rancière 2004, B. Massumi 2002, N. Bourriaud 2002 , M. Merleau-Ponty 1963) this research investigates the cultural and social rootedness (Verortung) of novel materials and technologies, exploring in between prosthetic relations between the body and the environment.
Bürgerliches Recht
(2019)
Die neunte Auflage deckt die wesentlichen Inhalte des zivilrechtlichen Lehrstoffes ab. Es werden in kompakter Form der Allgemeine Teil des BGB, das (Allgemeine und Besondere) Schuldrecht sowie das Sachenrecht dargestellt. Vervollständigt wird dieses Buch mit einem abschließenden Kapitel zum Zivilprozessrecht. Geschult werden das Verständnis für die Strukturen und Zusammenhänge im Bürgerlichen Recht und das Verständnis für die Verbindungen mit dem Zivilprozessrecht. Eine Vielzahl von Beispielen aus der Praxis, einprägsame Illustrationen, zahlreiche Schemata und Fälle mit Lösungsvorschlägen ermöglichen damit gleichzeitig auch ein anwendungsorientiertes bzw. fallorientiertes Lernen. Seine inhaltliche Kompaktheit macht es so zu einem idealen studienbegleitenden Lehrbuch für Studierende an Universitäten, Hochschulen, Berufsakademien und anderen Bildungseinrichtungen.
Die Hitzewellen der Sommer 2003 und 2015 zeigten wie kritisch langanhaltende Trockenheit nicht nur für die Natur, sondern auch für wassernutzende Unternehmen werden kann. Infolge des Klimawandels wird es entlang der Gewässer Baden-Württembergs immer wieder zu verschärften Niedrigwassersituationen kommen, was unter Umständen zu Wassernutzungskonflikten mit anderen Nutzern führt. Innerhalb dieses KLIMOPASS Projektes liegt der Fokus auf der Identifikation von vorhandenen und im Zuge des Klimawandels potenziell auftretenden lnteressens- und Nutzungskonflikten um die Ressource Wasser. Der Forschungsschwerpunkt bezieht sich hierbei auf zwei beispielhafte Fluss-Einzugsgebiete in Baden-Württemberg (die Murg und der Kocher) sowie aller beteiligten Akteure bzw. Wasserge- und -verbraucher (Energienutzung, Landwirtschaft, kommunale Entwässerung, Tourismus, Ökologie, etc.).
Anhand des Kochers und der Murg wurden mit Hilfe von Umfragen, Experteninterviews und Workshops Nutzungskonflikte identifiziert sowie Handlungsoptionen für eine Niedrigwasservorsorge und ein Niedrigwassermanagement erstellt. Dabei galt es ökonomische, gesellschaftliche und ökologische Belange möglichst adäquat zu berücksichtigen und sämtliche relevanten Akteure (Stakeholder) in einen partizipativen Prozess zu integrieren. Den Erhebungen zufolge treten Wassernutzungskonflikte nicht allgemein sektorenübergreifend auf, sondern sektorenspezifisch. Hierbei stehen die in Konflikte verwickelten Sektoren charakteristischerweise mit mehreren Stakeholder-Gruppen im Widerstreit, andere Akteursgruppen haben wiederum keinerlei Erfahrung mit Konflikten. Weiterhin ist auffällig, dass Niedrigwassersituationen an beiden untersuchten Flüssen lediglich einen Teil der Nutzungskonflikte ausmachen und verstärkt mit anthropogenen Einflüssen in Verbindung gebracht werden.
Engineering and management

Low temperature carburizing of a series of austenitic stainless with various combinations of chromium and nickel equivalents was performed. The investigation of the response towards low temperature carburized for three stainless steels with various Cr- and Ni-equivalents showed that the carbon uptake depends significantly on the chemical composition of the base material. The higher carbon content in the expanded austenite layer of specimen 6 (1.4565) and specimen 4 (1.4539/AISI 904L) compared to specimen 2 (1.4404/AISI 316L) is assumed to be mainly related to the difference in the specimens’ chromium content. More chromium leads to more lattice expansion. Along with the higher carbon content, higher hardness values and higher compressive residual stresses in the expanded austenite zone are introduced than for low temperature carburized AISI 316L. The residual stresses obtained from X-ray diffraction lattice strain investigation depend strongly on the chosen X-ray elastic constants. Presently, no values are known for carbon (or nitrogen) stabilized expanded austenite. Nevertheless, first principle elastic constants for γ′&minus Fe4C appear to provide realistic residual stress values. Magnetic force microscopy and measurement with an eddy current probe indicate that austenitic stainless steels can become ferromagnetic upon carburizing, similar for low temperature nitriding. The apparent transition from para- to ferromagnetism cannot be attributed entirely to the interstitially dissolved carbon content in the formed expanded austenite layer but appears to depend also on the metallic composition of the alloy, in particular the Ni content.
We present an innovative decision support system (DSS) for distribution system operators (DSO) based on an artificial neural network (ANN). A trained ANN has the ability to recognize problem patterns and to propose solutions that can be implemented directly in real time grid management. The principle functionality of this ANN based optimizer has been demonstrated by means of a simple virtual electrical grid. For this grid, the trained ANN predicted the solution minimizing the total line power dissipation in 98 percent of the cases considered. In 99 percent of the cases, a valid solution in compliance with the specified operating conditions was found. First ANN tests on a more realistic grid, calibrated with household load measurements, revealed a prediction rate between 88 and 90 percent depending on the optimization criteria. This approach promises a faster, more cost-efficient and potentially secure method to support distribution system operators in grid management.
Drawing on a rich body of multimethod field research, this book examines the ways in which Indonesian and Philippine religious actors have fostered conflict resolution and under what conditions these efforts have been met with success or limited success.
The book addresses two central questions: In what ways, and to what extent, have post-conflict peacebuilding activities of Christian churches contributed to conflict transformation in Mindanao (Philippines) and Maluku (Indonesia)? And to what extent have these church-based efforts been affected by specific economic, political, or social contexts? Based on extensive fieldwork, the study operates with a nested, multi-dimensional, and multi-layered methodological concept which combines qualitative and quantitative methods. Major findings are that church-based peace activities do matter, that they have higher approval rates than state projects, and that they have fostered interreligious understanding.
Through innovative analysis, this book fills a lacuna in the study of ethno-religious conflicts. Informed by the novel Comparative Area Studies (CAS) approach, this book is strictly comparative, includes in-case and cross-case comparisons, and bridges disciplinary research with Area Studies. It will be of interest to academics in the fields of conflict and peacebuilding studies, interreligious dialogue, Southeast Asian Studies, and Asian Politics.
Zusammenfassende Darstellung der Ergebnisse einer empirischen Studie über Friedens- und Postkonfliktarbeit durch kirchliche Akteure in Indonesien ( Maluku) und auf den Philippinen (Mindanao). Auf Basis der Untersuchung ziehen die Autoren Schlussfolgerungen über die praktische Bedeutung kirchlicher Friedensprojekte nach Konflikten
The reliable supply of energy is an essential prerequisite for the economic success of a country. Questions of sustainability and the replacement of import dependencies require new tasks with new approaches. This contribution provides an overview of dependencies using the example of German electrical power grids integrating renewable energies. Aspects of energy trading and grid stability are brought into connection, stock exchange trading, grid codes and volatility of used primary energies are discussed.
We have introduced in this paper new variants of two methods for projecting Supply and Use Tables that are based on a distance minimisation approach (SUT-RAS) and the Leontief model (SUT-EURO). We have also compared them under similar and comparable exogenous information, i.e.: with and without exogenous industry output, and with explicit consideration of taxes less subsidies on products. We have conducted an empirical assessment of all of these methods against a set of annual tables between 2000 and 2005 for Austria, Belgium, Spain and Italy. From the empirical assessment, we obtained three main conclusions: (a) the use of extra information (i.e. industry output) generally improves projected estimates in both methods; (b) whenever industry output is available, the SUT-RAS method should be used and otherwise the SUT-EURO should be used instead; and (c) the total industry output is best estimated by the SUT-EURO method when this is not available.
Business coaching is believed to effectively improve survival and success chances of new technology-based firms (NTBFs). However, not much empirical evidence on the support measure's effectiveness is available. Therefore, a pragmatic two-armed Randomized Controlled Trial (RCT) to test the effect of tactical business coaching on NTBF survival capabilities was designed and, for the most part, carried out. However, due to a lower than expected sample size and great attrition between groups, the RCT reveals deviations from the trial design that impede a thorough data assessment. Based on the data given, a first data analysis does not reveal significant differences in survival capability between the two groups. Thus, to provide guidance for future RCTs in business contexts, lessons learned about how to deal with trickle samples and experiment constellations with third parties carrying out the intervention are drawn.
In this paper, multivariate polynomials in the Bernstein basis over a box (tensorial Bernstein representation) are considered. A new matrix method for the computation of the polynomial coefficients with respect to the Bernstein basis, the so-called Bernstein coefficients, is presented and compared with existing methods. Also matrix methods for the calculation of the Bernstein coefficients over subboxes generated by subdivision of the original box are proposed. All the methods solely use matrix operations such as multiplication, transposition and reshaping; some of them rely on the bidiagonal factorization of the lower triangular Pascal matrix or the factorization of this matrix by a Toeplitz matrix. In the case that the coefficients of the polynomial are due to uncertainties and can be represented in the form of intervals it is shown that the developed methods can be extended to compute the set of the Bernstein coefficients of all members of the polynomial family.
Viele touristische Aktivitäten sind mit einem erhöhten Energiebedarf (Strom, Wärme, Kraftstoffe) verbunden, sodass Tourismus nicht losgelöst von der Energiewirtschaft bzw. deren Klimawirksamkeit zu betrachten ist. Das Projekt befasst sich daher mit der Triade Tourismus, Klimawandel und erneuerbare Energienutzung.
Die Veränderungen des Klimas stellen den Tourismus vor neue Herausforderungen. Um diesen Herausforderungen, im Sinne eines nachhaltigen Tourismus gerecht zu werden, kann der Tourismus dem Klimawandel mit Anpassungs- und/oder Vermeidungsstrategien begegnen (vgl. ELSASSER ET AL. 2000). Im Rahmen dieses Projektes werden sowohl mögliche Anpassungs- als auch Vermeidungsstrategien thematisiert. Ein besonderer Fokus wird dabei zum einen auf die Nutzung von erneuerbaren Energien (EE) gelegt. Zum anderen werden die Entwicklungen des Tourismus und die Anpassungen an die Änderungen des Klimas vornehmlich in Bezug auf den Wintertourismus betrachtet. Räumlich konzentriert sich das Projekt auf das Mittelgebirge Schwarzwald.
Border issues continue to be of interest in tourism literature, most significantly that which focusses on cross-border shopping (e.g., currency values, taxation,
security). Borders as destinations are recognized in this area but the notion of shopping as a destination is perhaps less acknowledged. Following a review of the relevant literature, including the presentation of a table summarizing key areas of cross-border tourism research around the world, this paper presents a unique example of a border region with two-way traffic for cross-border shopping tourism: the border between Germany and Switzerland.
The particular case is where two cities meet at the border: Konstanz, Germany and Kreuzlingen, Switzerland. An intercept survey and key informant interviews were conducted in both communities in the spring of 2015. The results indicate high levels of traffic for various products and services. And while residents are generally satisfied with cross-border shopping in their communities, there are emerging issues related to volume and, in particular, too many in Konstanz and not enough in Kreuzlingen.
The paper concludes with a discussion that includes the development of a model cross-border shopping tourism that recognizes the multiple layers in space and destination.
The paper concludes with a proposal to further investigate the particular issues related to the volume on both sides of borders where cross-border shopping is the destination.
Die Bodenseeregion gilt als populäre Freizeit- und Tourismusdestination, mit der ein vielfältiger Naturraum, ein angenehmes Klima sowie eine fruchtbare Landwirtschaft verbunden werden. Der Kulturtourismus ist dabei – je nach Bodenseedestination in unterschiedlich starker Ausprägung – nicht nur ein wichtiger Baustein für die Erweiterung der touristischen Angebotspalette, sondern auch ein wesentlicher Faktor für die Lebensqualität am Bodensee.
Für die Tourismuswirtschaft und insbesondere den Kulturtourismus ist die Inanspruchnahme von Knowhow der Kreativwirtschaft z. B. in Form von Produkten und Dienstleistungen des Presse-, Rundfunk-, Software-, und Werbemarkts unverzichtbar. Die Kreativwirtschaft ist mit Teilmärkten wie der Musikwirtschaft, den darstellenden Künsten oder dem Kunstmarkt ein wichtiger Inhaltslieferant für kulturtouristische Angebote.
Purpose – The purpose of this paper is to examine visitor management in the German-Swiss border area of the Lake Constance region. Taking a customer perspective, it determines the requirements for an application with the ability to optimize personal mobility.
Design/methodology/approach – A quantitative study and a survey of focus groups were conducted to identify movement patterns of different types of visitors and their requirements concerning the development of a visitor management application.
Findings – Visitors want an application that provides real-time forecasts of issues such as traffic, parking and queues and, at the same time, enables them to create a personal activity schedule based on this information.
Research limitations/implications – Not every subsample reached a sufficient number of cases to yield representative results.
Practical implications – The results may lead to an optimization and management separation of mobility flows in the research area and be helpful to municipal planners, destination marketing organizations and visitors.
Originality/value – The German border cities of Konstanz, Radolfzell and Singen in the Lake Constance region need improved visitor management, mainly because of a high level of shopping tourism by Swiss visitors to Germany. In the Summer months, Lake Constance is also a popular destination for leisure tourists, which causes overtourism. For the first time, the results of this research presented here offer possible solutions, in particular by showing how a mobile application for visitors could defuse the situation.
