Der betriebswirtschaftlichen Forschung in der Textil- und Bekleidungsindustrie gelingt es nicht, Lösungen zu erarbeiten, die das Nachhaltigkeitsproblem der Branche lösen. Dies liegt primär an der Art und Weise, wie in unserem Fachbereich geforscht wird. In Anbetracht der Problemstellung kann der starke Fokus auf empirische Arbeiten nur eine begrenzte Hilfestellung leisten. Denn empirische Forschung erfolgt innerhalb der bestehenden Denkmuster und ist tendenziell gegenwarts- oder vergangenheitsorientiert. Für die Lösung zukunftsorientierter Fragestellungen werden jedoch völlig neue Parameter und Logiken benötigt. Ein Umdenken ist gefragt.
This study analyses the impact of Basel III on the fair pricing of bank guarantee facilities.Guarantees are an important risk mitigation instrument between exporters and importers in international trade and regularly a prerequisite for cross border sales contracts to be closed. Basel III – which shall be introduced from 2013 onwards - is a new regulation stipulating higher capital requirements for banks compared to the predecessor Basel II. It will therefore have an impact on the pricing of guarantee facilities which banks provide to exporting companies, making it also a crucial regulation for the cost of exportation overall. The study compares those contents of Basel III and Basel II which are particularly relevant for guarantees in order to identify and crystallize pricing-relevant changes in the regulations and their respective impact potential. The Basel frameworks are analyzed part by part and reviewed in terms of relevance for guarantees. In case of ambiguity the analysis is verified by complementary expert interviews. References and examples are mainly focusing on the German banking system but the basic conclusions can be generalized for those countries adopting Basel III.1 As the result, a case study expresses the quantitative outcomes of different scenarios and the impact of the different price determining factors on the overall fair pricing of bank guarantee facilities.
In order to decouple economic growth from global material consumption it is necessary to implement material efficiency strategies at the level of single enterprises and their supply chains, and to implement circular economy aspects. Manufacturing firms face multiple implementation challenges like cost limitations, competition, innovation and stakeholder pressure, and supplier and customer relationships, among others
. An extended evaluation of triggers and barriers to improve material efficiency in manufacturing companies, along the supply chain and concerning circular economy considerations is provided. This paper delivers an extended literature review, a critical discussion of the current situation and resulting challenges concerning material efficiency approaches in manufacturing supply chains. Finally, a conclusion and outlook on further research direction is given.
In order to evaluate the performance of different stapes prosthesis types, a coupled finite element (FE) model of human ear was developed. First, the middle-ear FE model was developed and validated using the middle-ear transfer function measurements available in literature including pathological cases. Then, the inner-ear FE model was developed and validated using tonotopy, impedance, and level of cochlea amplification curves from literature. Both models are based on pre-existing research with some improvements and were combined into one coupled FE model. The stapes in the coupled FE ear model was replaced with a model of a stapes prosthesis to create a reconstructed ear model that can be used to estimate how different types of protheses perform relative to each other as well as to the natural ear. This will help in designing of new innovative types of stapes prostheses or any other type of middle-ear prostheses as well as to improve the ones that are already available on the market.
Im Management von Sportvereinen wächst zusehends der Anspruch im Markt als professionelles Wirtschaftsunternehmen zu agieren, wobei auch Marken-Überlegungen zunehmend strategische Bedeutung erhalten. Die hier in Ausschnitten vorgestellten Studie "Marken im deutschen Profisport 2012/2013" untersucht die Selbst- und Fremdwahrnehmung der Vereine der fünf umsatzstärksten Teamsportligen in Deutschland (1. und 2. Fußballbundesliga, Handballbundesliga, Basketballbundesliga, Deutschen Eishockey Liga). Die Studienergebnisse basieren auf Meinungen von insgesamt 4.678 befragten Sportfans, sowie 58 Vereinen. Dabei wird vor allem festgestellt, dass eine teils erhebliche Diskrepanz zwischen dem eigenem Anspruch vieler Clubs und dem tatsächlichen Markenimage vorherrscht. Nur gerade einmal elf Clubs werden von den Fans als "echte Marke" wahrgenommen. Kernpunkt der Studie ist ein von den Autoren entwickeltes Klassifizierungssytem für Sportmarken, das zukünftig als Grundlage für markenrelevante Entscheidungen dienen könnte.
In this work, a web-based software architecture and framework for management and diagnosis of large amounts of medical data in an ophthalmologic reading center is proposed. Data management for multi-center studies requires merging of standing data and repeatedly gathered clinical evidence such as vital signs and raw data. If ophthalmologic questions are involved the data acquisition is often provided by non-medical staff at the point of care or a study center, whereas the medical finding is mostly provided by an ophthalmologist in a specialized reading center. The study data such as participants, cohorts and measured values are administrated at a single data center for the entire study. Since a specialized reading center maintains several studies, the medical staff must learn the different data administration for the different data center. With respect to the increasing number and sizes of clinical studies, two aspects must be considered. At first, an efficient software framework is required to support the data management, processing and diagnosis by medical experts at the reading center. In the second place, this software needs a standardized user-interface that has not to be trained/taylore /adapted for each new study. Furthermore different aspects of quality and security controls have to be included. Therefore, the objective of this work is to establish a multi purpose ophthalmologic reading center, which can be connected to different data centers via configurable data interfaces in order to treat various topics simultaneously.
In this article we would like to link certain developments of the Cryptocurrency price movement to the five characteristic phases speculative bubbles undergo according to US economists Charles Kindleberger and Hyman Minsky, who developed the respective framework in "Manias, panics and crashes" (1978). Although every speculative bubble is somewhat different, they tend to follow five phases.In addition, we would like to answer the question how speculative bubbles develop and why they suddenly collapse.
Indicators of disruption potentials - analysis of the blockchain technology’s potential impact
(2019)
The goal of this paper was to answer the question whether blockchain has the potential to become a disruption according to Clayton Christensen’s disruption theory. Therefore, the theory and the five characteristics that define the process of disruption were outlined in the first part of the paper. That and the following explanation of the blockchain technology served as the basis for the analysis and evaluation in chapters four to seven. For the analysis, three applications of the DLT, namely payment methods, intermediaries, as well as data storage and transfer, were considered. The fulfillment of the five characteristics of disruption was assessed using an example for each of the three applications.
Additionally, the paper might serve as a basis for future research on the topic, once the technology develops further, since it is generally hard to tell whether the fourth and fifth characteristics are fulfilled by blockchain at this point. Therefore, the results of the paper also back criticism of Christensen’s theory regarding its usefulness for predictions.
This paper suggests that, in the financial services industry, too, the impact of blockchain will be significant. However, given the manifoldness of the services that are part of the industry, it cannot generally be concluded whether the DLT will disrupt the industry. For example, in services related to payment methods, blockchain is unlikely to follow disruptive pattern, despite the recent hype surrounding blockchain-based cryptocurrencies. However, regarding data storage and transfer, the technology might as well follow disruptive pattern in the financial services industry just as the application of blockchain solutions has been doing in the healthcare industry.
Die vorliegende Arbeit thematisiert die Identifizierung und Darstellung von Ansätzen, wie man Menschen zu einem besseren Entscheidungsverhalten bei Finanzprodukten und -dienstleistungen bewegen kann. Hierfür werden sogenannte Nudges bei Krediten, Kreditkarten, Hypotheken, der Altersvorsorge und Aktien/Anleihen erläutert. Die Arbeit beginnt mit einer knappen Einführung in die Entscheidungstheorie. Danach wird die seit Jahrzehnten dominierende neoklassische Kapitalmarktheorie kurz erläutert und der Bogen zur jungen Disziplin der Behavioral Finance gespannt. Im Anschluss daran werden Verzerrungen und Heuristiken entlang des Entscheidungsprozesses aufgezeigt und erklärt. Das nächste Kapitel, „Libertärer Paternalismus“, bildet den theoretischen Rahmen für Nudging. Im letzten Kapitel werden Nudgingansätze bei Krediten, Kreditkarten, Hypotheken, der Altersvorsorge und Aktien/Anleihen dargestellt.
