| alexander wohlfahrt: Nietzsche’s Nihilism in Walter Benjamin Mauro Ponzi, 2016-11-21 This book reconstructs the lines of nihilism that Walter Benjamin took from Friedrich Nietzsche that define both his theory of art and the avant-garde, and his approach to political action. It retraces the eccentric route of Benjamin's philosophical discourse in the representation of the modern as a place of “permanent catastrophe”, where he attempts to overcome the Nietzschean nihilism through messianic hope. Using conventions from literary criticism this book explores the many sources of Benjamin's thought, demonstrating that behind the materialism which Benjamin incorporates into his Theses on the Concept of History is hidden Nietzsche's nihilism. Mauro Ponzi analyses how Benjamin’s Arcades Project uses figures such as Baudelaire, Marx, Aragon, Proust and Blanqui as allegories to explain many aspects of modernity. The author argues that Benjamin uses Baudelaire as a paradigm to emphasize the dark side of the modern era, offering us a key to the interpretation of communicative and cultural trends of today. |

| alexander wohlfahrt: Das Arkansas Echo Kathleen Condray, 2020-11-13 In the late nineteenth century, a thriving immigrant population supported three German-language weekly newspapers in Arkansas. Most traces of the community those newspapers served disappeared with assimilation in the ensuing decades—but luckily, the complete run of one of the weeklies, Das Arkansas Echo, still exists, offering a lively picture of what life was like for this German immigrant community. “Das Arkansas Echo”: A Year in the Life of Germans in the Nineteenth-Century South examines topics the newspaper covered during its inaugural year. Kathleen Condray illuminates the newspaper’s crusade against Prohibition, its advocacy for the protection of German schools and the German language, and its promotion of immigration. We also learn about aspects of daily living, including food preparation and preservation, religion, recreation, the role of women in the family and society, health and wellness, and practical housekeeping. And we see how the paper assisted German speakers in navigating civic life outside their immigrant community, including the racial tensions of the post-Reconstruction South. “Das Arkansas Echo”: A Year in the Life of Germans in the Nineteenth-Century South offers a fresh perspective on the German speakers who settled in a modernizing Arkansas. Mining a valuable newspaper archive, Condray sheds light on how these immigrants navigated their new identity as southern Americans. |

[M-Commerce gleicht einem mit Glitter bestreuten Einkauftempel, welcher immer noch über eine tributreiche und dreckige Strasse mit dem Rest der Welt verbunden ist.] Die Diplomarbeit Möglichkeiten und Grenzen multimedialer Informations-technologien im Marketing behandelt ein neuartiges, sich derzeit erst konstituierendes Gebiet des Marketing, nämlich das M-Commerce. Das komplexe Thema wird dadurch bewältigt, dass der M-Commerce zunächst in das mobile Business eingeordnet wird und von dorther schrittweise die wirtschaftlichen, technischen, sozialen und rechtlichen Aspekte aufgerollt werden. Demnach wird die neue Form des Marketing nicht aus der Marketing-Sparte als solcher analytisch entwickelt (indem vor diesem Hintergrund das Neuartige aufscheint), sondern auf Grundlage einer - vom Autor angenommenen umfassenden Umwälzung der Lebens-, Kommunikations-, und Wirtschaftsweisen in heutigen Gesellschaften. Nach einer umfassenden, fächerübergreifenden Definition der einzelnen Termini, sowie die Beschreibung derer Besonderheiten und Bedeutung, rundet eine aktuelle Situationsanalyse, bezüglich des Vorliegenden, die Ausführungen zum Konzept des M-Commerce ab. Im Weiteren werden makro- und mikroökonomische, und technische Spezifika des M-Business erläutert, um konzeptimmanente Aspekte für Anbieter, Anleger und Investoren zu veranschaulichen. Den eher marketing-orientierten Interessengruppen seien Ausführungen hinsichtlich jüngster gesellschaftlich-sozialer Umwälzungen, sowie ein verändertes Konsumentenverhalten an die Hand gegeben. Neben dem mobilen Markt mit seinen Trends findet auch der unternehmensinterne Blickwinkel ausreichend Beachtung. Nachdem das Marketing-Management auf strategischem Level beleuchtet wird, kommt die operative Ebene stark zum tragen, da Marketing - in der vorliegenden Arbeit - als Begriff der Werbung als solche eingeordnet ist. In diesem Sinne bildet die multimediale Kommunikationspolitik als Teil des Marketing-Mix, das Hauptstandbein für diesen Textabschnitt. Neuartige Konzepte wie das Permission-Marketing und mobile CRM werden vorgestellt, und dienen als Argumentationsgrundlage für erfolgreiche mobile Werbung unter Vorbehalt der integrierten Verwendung. Sehr umfangreich erläuterte, rechtliche und sicherheitstechnische Gegebenheiten im M-Commerce bilden schlussendlich den [...] |

| alexander wohlfahrt: Germans on Welfare David F. Crew, 1998-04-23 The welfare state was one of the pillars of the Weimar Republic. The Weimar experiment in democracy depended to no small degree upon the welfare system's ability to give German citizens at least a fundamental level of material and mental security in the face of the new risks to which they had been exposed by the effects of the lost war, revolution, and inflation. But the problems of the postwar period meant that, even in its best years, the Weimar welfare state was dangerously overburdened. The onset of the Depression and the growth of mass unemployment after 1929 destroyed republican democracy and the welfare state upon which it was based. On the ruins of Weimars social republic, the Nazis built a murderous racial state. Existing work on the Weimar welfare state concentrates largely on the discussions of social reformers, welfare experts, feminists, and the laws and institutions that their debates produced. Yet the Weimar welfare state was not simply the product of discourse and discursive struggles; it was also constructed and re-produced by the daily interactions of hard-pressed officials and impatient, often desperate clients. Adopting a history of everyday life perspective, Germans on Welfare: From Weimar to Hitler, 1919-1935 shows how welfare discourse and policy were translated into welfare practices by local officials and appropriated, contested, or re-negotiated by millions of welfare clients. |

| alexander wohlfahrt: Germany’s Belt and Road Bargain Tim Banning, 2025-02-25 In recent years, the Belt and Road Initiative (BRI) has not only transformed global trade relations but also tested Germany’s political strategies. This book explores the German Federal Government’s ambivalent response to China’s politics of infrastructure investments under the BRI during Angela Merkel’s tenure as Chancellor, raising crucial questions about Germany’s bilateral relations with China, its economic ambition, and its geopolitical responsibility. This book provides a detailed account of the key political processes and decision points that influenced the Federal Government’s stance towards China’s politics of infrastructure investments. Through its analysis of the interactions between domestic politics and international relations, it aims to offer a nuanced understanding of the complex dynamics between the state and business. It examines how the varying interests of numerous industry sectors impacted the Federal Government’s response to China’s politics of infrastructure investments across multiple policy domains, covering Germany’s policy on foreign investments and foreign trade, its industrial policy, its broader foreign policy, and its role in European politics. |
| alexander wohlfahrt: Ascending China and the Hegemonic United States Jörg Vogelmann, 2020-09-04 Jörg Vogelmann looks into one of the central political and economic relationships of the 21st century. The author finds Sino-U.S. ties marked by strong, slightly asymmetric (economic) interdependence, a relatively fast economic power transition under way as well as slow to moderate shifts in military power. He develops a neoliberal and a neorealist grand theory picture of Sino-U.S. and international relations, and empirically verifies these influential perspectives by analyzing post-Cold War Chinese and U.S. foreign policies in the major flashpoints the Taiwan and the North Korea issue. Despite and due to globalization, ties between ascending China (as a potential regional or once even global U.S. challenger) and the hegemonic United States may likely continue to be marked by strategic power politics – and will decisively affect trans- and international relations. |

| alexander wohlfahrt: The Oxford Handbook of German Politics Klaus Larres, Holger Moroff, Ruth Wittlinger, 2022-07-18 Few countries have caused or experienced more calamities in the 20th century than Germany. The country emerged from the Cold War as a newly united and sovereign state, eventually becoming Europe's indispensable partner for all major domestic and foreign policy initiatives. This handbook provides a comprehensive overview of some of the major issues of German domestic politics, economics, foreign policy, and culture by leading experts in their respective fields. This book serves primarily as a reference work on Germany for scholars and an interested public, but through this broader lens it also provides a magnifying glass of global developments which are challenging and transforming the modern state. The growing importance of Germany as a political actor and economic partner makes this endeavor all the more timely and pertinent from a German, European, and global perspective. |
| alexander wohlfahrt: Orthodox Christian Identity in Western Europe Sebastian Rimestad, 2020-11-19 This book analyses the discourses of Orthodox Christianity in Western Europe to demonstrate the emerging discrepancies between the mother Church in the East and its newer Western congregations. Showing the genesis and development of these discourses over the twentieth century, it examines the challenges the Orthodox Church is facing in the modern world. Organised along four different discursive fields, the book uses these fields to analyse the Orthodox Church in Western Europe during the twentieth century. It explores pastoral, ecclesiological, institutional and ecumenical discourses in order to present a holistic view of how the Church views itself and how it seeks to interact with other denominations. Taken together, these four fields reveal a discursive vitality outside of the traditionally Orthodox societies that is, however, only partly reabsorbed by the church hierarchs in core Orthodox regions, like Southeast Europe and Russia. The Orthodox Church is a complex and multi-faceted global reality.Therefore, this book will be a vital guide to scholars studying the Orthodox Church, ecumenism and religion in Europe, as well as those working in religious studies, sociology of religion, and theology more generally. |

Bei den potenziellen Nutzern existieren jedoch zum Teil große Ängste hinsichtlich der Verletzung ihrer Privatsphäre bei der Preisgabe der benötigten Standortdaten. Vor dem Hintergrund der Unzulänglichkeiten gesetzlicher Regelungen fällt dem Vertrauensverhältnis von Konsumenten zu Anbietern die zentrale Rolle zur Begegnung der resultierenden Unsicherheiten zu. Für die Öffnung des Marktes und zur Stärkung der eigenen Wettbewerbsposition in einem Markt mit schwindenden Wechselbarrieren und zunehmender Wettbewerbsintensität stellt daher die aktive Stärkung der Vertrauenswürdigkeit einen entscheidenden Wettbewerbsfaktor für Anbieter von Location Based Services dar. Welche Möglichkeiten haben Anbieter, ein vorbeugendes Vertrauensmanagement zu betreiben?

| alexander wohlfahrt: Detection and characterization of Lithium plating Long, Julian, 2023-05-31 Lithium plating is not only the most severe ageing mechanism in lithium-ion batteries (LIBs) but also becoming more and more important due the increasing presence of electric vehicles (EVs). In EVs the extreme conditions causing lithium plating, like very high charging currents and low environment temperatures, are much more prevalent than in consumer electronics. Due to the high number of factors that influence the plating process, ranging from the cell geometry to the chemical composition of the electrolyte, a deeper understanding of the plating process is still lacking. Without this knowledge it is hard to design cells in a plating resistant way, or to operate cells under the ideal conditions to minimize plating. This thesis aims at showing different methods to investigate the plating process on three different levels. The first method is on the cell level, investigating the behaviour of the whole cell during plating. It contains the analysis of the voltage and current profiles that show an atypical behaviour during plating. The focus of the analysis is on the current profile of the constant voltage (CV) phase during charging under low temperature conditions leading to plating. This current profile can be fitted with the Johnson-Mehl-Avrami-Kolmogorov (JMAK) function that describes the electrochemical deposition process of a metallic species on a surface. The resulting fitting parameters can be utilized to characterize the plating behaviour of the cell as well as better estimate the amount of plated lithium than commonly used methods. It can also potentially predict the future safety risk due to dendrite formation. In the second part the chemical composition of the surface electrolyte interface (SEI) is investigated using X-ray photoelectron spectroscopy (XPS). The composition as well as the mechanical properties of the SEI are strongly influencing the plating process and preliminary work has shown that plating is also changing the morphology of the SEI and increasing its thickness drastically. Cells under different conditions (plated, charged and discharged) as well as cells of different manufacturers have been probed using XPS. During the measurements an unwanted side effect of the experimental setup was discovered that lead to a migration of lithium to the surface of the sample and was distorting the measurement results. Regardless of the effect, it was possible to see that the SEI can have a very different composition in cells of different manufacturers and that plating not only changes the morphology but also the composition of the SEI. The unwanted side effect could furthermore be utilized to identify samples that were plated recently and could be used in further more controlled experiments to localize lithium depositions on plated samples. In the last part the particle structure of the anode surface of cells of different manufacturers was investigated using a watershed particle detection algorithm on laser scanning microscopy (LSM) images of the anode surfaces. The distributions of the particle sizes have then been compared to the capacity loss in plated cells. It was shown that the capacity loss correlates with parameters extracted from the particle size distributions. It is however necessary to create more data to verify this correlation. In summary this thesis utilized new methods to detect or characterize plating on different levels of magnification, from the cell level to the chemical composition. New approaches were found to predict a cells future plating behaviour, spatially localize plated areas on the anode and design cells in a plating resistant way. Lithium Plating ist nicht nur der Alterungsmechanismus in Lithium-Ionen-Batterien mit dem größten Kapazitätsverlust, sondern wird auch im Zuge der voranschreitenden Elektrifizierung des Personenverkehrs immer wichtiger. In Elektrofahrzeugen finden sich die extremen Zustände, wie niedrige Ladetemperaturen und hohe Ladestrome, unter denen Plating auftritt, deutlich häufiger als in Unterhaltungstechnik. Durch die Vielzahl von Parametern, von der Zellgeometrie bis hin zur Elektrolyzusammensetzung, die Plating beeinflussen, fehlt immer noch ein tieferes Verständnis des Plating-Prozesses. Ohne dieses Wissen ist es schwer, Zellen zu designen, die resistent gegen Plating sind oder Zellen unter optimalen Bedingungen zu betreiben um Plating zu minimieren. Das Ziel dieser Arbeit ist es, verschiedene Methoden aufzuzeigen, die die Untersuchung von Plating auf drei verschiedenen Ebenen ermöglichen. Die erste Methode untersucht das Gesamtverhalten der Zelle auf Zellebene. Hierbei wird das atypische Verhalten der Strom- und Spannunsprofile wahrend des Plating-Vorgangs analysiert. Der Fokus liegt dabei auf der Untersuchung der Konstantstrom-Phase bei niedrigen Temperaturen während der Ladung. Das Stromprofil dieser Phase kann mit der JMAK-Funktion gefittet werden, welche die elektrochemische Abscheidung eines Metalls auf einer Oberfläche beschreibt. Die resultierenden Fitting-Parameter können genutzt werden, um das Plating-Verhalten vorherzusagen und sind gleichzeitig eine bessere Abschätzung fur die Menge an geplatetem Lithium im Vergleich zu gängigen Methoden. Die Ergebnisse konnten außerdem helfen das Sicherheitsrisiko der Zelle bei Dendritenbildung vorherzusagen. Im zweiten Teil wird die chemische Zusammensetzung der SEI mittels XPS untersucht. Die Zusammensetzung, wie auch die mechanischen Eigenschaften der SEI, beeinflussen den Plating-Prozess stark und es wurde in vorhergehenden Arbeiten gezeigt, dass Plating auch die Morphologie und Dicke der SEI drastisch verändern kann. Zellen in verschiedenen Zuständen (geplatet, geladen, entladen), sowie Zellen verschiedener Hersteller wurden mit XPS untersucht. Während der Messungen wurde ein ungewollter Nebeneffekt des Messaufbaus entdeckt, der zu einer Migration von Lithium an die Oberflache der Proben geführt und die Messergebnisse verfälscht hat. Unabhängig von diesem Effekt war es dennoch möglich, zu zeigen, dass die SEI in Zellen verschiedener Hersteller stark unterschiedliche Zusammensetzungen haben kann und dass Plating nicht nur die Morphologie der SEI beeinflusst, sondern auch die chemische Zusammensetzung. Weiterhin konnte der ungewollte Nebeneffekt verwendet werden, um Proben zu identifizieren, die vor kurzem geplatet wurden und konnte in zukünftigen Arbeiten verwendet werden, um lokalisiert Lithium-Ablagerungen auf geplateten Proben zu identifizieren. Im letzten Teil wurde die Partikelstruktur der Anoden von Zellen verschiedener Zellhersteller mit Hilfe einer watershed-Partikeldetektion an LSM-Bildern untersucht. Die Verteilung der Partikelgrößen wurde mit dem Kapazitätsverlust gleicher Zelle durch Plating verglichen. Es wurde gezeigt, dass der Kapazitätsverlust mit Parametern, die aus den Partikelverteilungen extrahiert wurden, korreliert. Ein größerer Datensatz ist jedoch notwendig, um diese Ergebnisse zu validieren. Zusammenfassend hat diese Arbeit verschiedene neue Methoden aufgezeigt, um Plating auf verschiedenen Vergrößerungsebenen zu detektieren und zu charakterisieren. Neue Ansätze wurden gefunden, um das Platingverhalten von Zellen vorherzusagen, lokalisiertes Lithium auf der Oberfläche zu detektieren und Zellen platingresistenter designen zu können. |
