Für Educational Excellence muss die Ausbildung angehender Akademiker den Spagat zwischen Wissenschaft und Praxis meistern. Einfache Praktika u. a. klassische Ansätze reichen für Educational Excellence, angelehnt an die Anforderungen der Operational Excellence, nicht aus. Vorgestellt wird das an der ESB Business School der Hochschule Reutlingen seit vielen Jahren in der Wirtschaftsingenieurausbildung für Produktion und Logistik in einem Projekt-Masterstudiengang mit vielen Industriepartnern praktizierte kooperative Modell der Educational Excellence.
Durch die Digitalisierung der Arbeitswelt und die New Work-Bewegung verändert sich die Art und Weise, wie wir zu-ammenarbeiten. Entsprechend wird derzeit viel über Führung gesprochen – möglicherweise zu viel. Die zentrale These des Beitrags ist, dass wir besser verstehen können, wie Führungskräften und Mitarbeitende zukunftsorientiert zusam-menarbeiten, wenn wir weniger direkt über Führung reden, sondern zunächst von der Situation aus denken, in der sich Akteure koordinieren. Führung wird dann nicht isoliert, sondern zusammen mit verschiedenen Koordinationsformen betrachtet (wie Autonomie, Selbstorganisation, Management und eben Führung). Das kann in der Praxis helfen, den Wandel der Zusammenarbeit – inklusive der neuen Art von Führung – reflektierter und zielorientierter zu gestalten.
In modernen Arbeitswelten werden zunehmend arbeitsplatzbezogene digitale Technologien eingesetzt. Wenngleich dies zahlreiche Chancen bietet, kann es auch negative Folgen für die Gesundheit von Mitarbeitenden haben. Diese Herausforderungen werden durch die aktuelle Corona-Krise für viele Unternehmen noch verschärft. Stress, der direkt oder indirekt durch den Einsatz von Technologien entsteht, wird als «Technostress» bezeichnet. Wichtige Hebel zu dessen Vermeidung umfassen die Gestaltung von Technologien sowie die Berücksichtigung verschiedener individueller und situativer Faktoren im Rahmen technologischer Veränderungsprozesse.
Problem: Immer mehr Unternehmen führen Lean-Prinzipien ein, finden ihre Anforderungen an passende Kosteninformation aber von der traditionellen Kostenrechnung nicht ausreichend abgedeckt.
Ziel: Eine am Lean-Gedanken orientierte Kostenrechnung baut neue Kostenzurechnungsobjekte ein und stellt bisher vernachlässigte Kosteninformationen zur Verfügung
Methode: Gängige Kostenrechnungsansätze werden einem geschlossenen “accounting for lean” Ansatz gegenübergestellt, Gemeinsamkeiten und Überschneidungen aufgezeigt.
Gibt es einen Kauf-Knopf im Gehirn des Konsumenten? Und wenn ja, wie betätigt man diesen? Die Antworten auf diese Fragen könnte das Neuromarketing liefern. Das Neuromarketing ist Bestandteil der Neuroökonomie und eine relativ junge Disziplin an der Schnittstelle von Kognitionswissenschaften, Neurowissenschaften und der Marktforschung. Durch den technologischen Fortschritt können die Neurowissenschaften wichtige Erkenntnisse für das Marketing liefern, insbesondere Einblicke zur Erklärung des Konsumentenverhaltens. Durch den Blick in das Kundengehirn können beispielsweise Handelsunternehmen ihre Kunden gezielter ansprechen und sich so einen Vorteil gegenüber Konkurrenten verschaffen.
Purpose: Despite growing interest in the intersection of supply chain management (SCM) and management accounting (MA) in the academic debate, there is a lack of understanding regarding both the content and the delimitation of this topic. As of today, no common conceptualization of supply chain management accounting (SCMA) exists. The purpose of this study is to provide an overview of the research foci of SCMA in the scholarly debate of the past two decades. Additionally, it analyzes whether and to what extent the academic discourse of MA in SCs has already found its way into both SCM and MA higher education, respectively.
Design/methodology/approach: A content analysis is conducted including 114 higher education textbooks written in English or in German language.
Findings: The study finds that SC-specific concepts of MA are seldom covered in current textbooks of both disciplines. The authors conclude that although there is an extensive body of scholarly research about SCMA concepts, there is a significant discrepancy with what is taught in higher education textbooks.
Practical implications: There is a large discrepancy between the extensive knowledge available in scholarly research and what we teach in both disciplines. This implies that graduates of both disciplines lack important knowledge and skills in controlling and accounting for SCs. To bring about the necessary change, MA and SCM in higher education must be more integrative.
Originality/value: To the best of the authors knowledge, this study is first of its kind comprising a large textbook sample in both English and German languages. It is the first substantiated assessment of the current state of integration between SCM and MA in higher education.
By 2019, German-based Kärcher, "the world's leading provider of cleaning technology", hat turned its professional cleaning devices into digital offerings. The data generated by these connected cleaning devices formed a key ingredient in the company's ongoing strategic shift in its B2B business: Kärcher was transforming from a seller of cleaning devices to a provider of consulting services in order to help professional cleaning companies improve their cleaning processes.
The case illustrates how the company learned to generate value from digital offerings. And it demonstrates how a family-owned company transformed its organization in order to be able to more effectively develop and provide digital offerings, while adding roles and developing technology platforms, as well as changing structures and ways of working.
Formula One races provide a wealth of data worth investigating. Although the time-varying data has a clear structure, it is pretty challenging to analyze it for further properties. Here the focus is on a visual classification for events, drivers, as well as time periods. As a first step, the Formula One data is visually encoded based on a line plot visual metaphor reflecting the dynamic lap times, and finally, a classification of the races based on the visual outcomes gained from these line plots is presented. The visualization tool is web-based and provides several interactively linked views on the data; however, it starts with a calendar-based overview representation. To illustrate the usefulness of the approach, the provided Formula One data from several years is visually explored while the races took place in different locations. The chapter discusses algorithmic, visual, and perceptual limitations that might occur during the visual classification of time-series data such as Formula One races.
Companies compete more and more as integrated supply chains rather than as individual firms. The success of the entire supply chain determines the economic well-being of the individual company. With management attention shifting to supply chains, the role of management accounting naturally must extend to the cross-company layer as well. This book demonstrates how management accounting can make a significant contribution to supply chain success.It targets students who are already familiar with the fundamentals of accounting and now want to extend their expertise in the field of cross company (or network) management accounting. Practitioners will draw valuable insights from the text as well.
Energieversorgungsunternehmen sehen sich gegenwärtig und mit dem Voranschreiten der Energiewende mit einer Vielzahl von Herausforderungen konfrontiert. Die zunehmende Dezentralisierung und Digitalisierung der Energiewirtschaft zwingen die EVU zusammen mit dem steigenden Wettbewerbs- und Kostendruck dazu, von den gewohnten Pfaden des Commodity-Geschäfts abzuweichen und neue Produkte und Dienstleistungen zu entwickeln sowie neue Geschäftsfelder zu erschließen. Die Kunden rücken mit ihren zunehmend individualisierten und komplexen Bedürfnissen in den Mittelpunkt des Interesses. Wollen EVU langfristig am Markt erfolgreich sein, müssen sie sich vom klassischen Energieversorger als Anbieter von einfachen Produkten hin zu innovativen, kundenzentrierten Energiedienstleistern weiterentwickeln. Ein Schlüssel hierfür stellt die Entwicklung von Energiedienstleistungen dar. Gleichzeitig tun sich viele EVU mit dieser Entwicklung jedoch aufgrund interner Hemmnisse wie fehlender personeller Kapazitäten, einer angesichts des dynamischen Marktumfeldes unflexiblen Organisation mit langen Entwicklungsdauern, geringen Budgets sowie mangelndem fachlichen und/ oder methodischen Know-How schwer. Dies zeigen die Ergebnisse der vorliegenden Studie unter Geschäftsführern und Vorständen in der Energiewirtschaft.
Background. We describe and provide an initial evaluation of the Climate Action Simulation, a simulation-based role playing game that enables participants to learn for themselves about the response of the climate-energy system to potential policies and actions. Participants gain an understanding of the scale and urgency of climate action, the impact of different policies and actions, and the dynamics and interactions of different policy choices.
Intervention. The Climate Action Simulation combines an interactive computer model, En-ROADS, with a role play in which participants make decisions about energy and climate policy. They learn about the dynamics of the climate and energy systems as they discover how En-ROADS responds to their own climate-energy decisions.
Methods. We evaluated learning outcomes from the Climate Action Simulation using pre- and post-simulation surveys as well as a focus group.
Results. Analysis of survey results showed that the Climate Action Simulation increases participants’ knowledge about the scale of emissions reductions and policies and actions needed to address climate change. Their personal and emotional engagement with climate change also grew. Focus group participants were overwhelmingly positive about the Climate Action Simulation, saying it left them feeling empowered to make a positive difference in addressing the climate challenge.
This study investigates empirically the development of working capital management and its impact on profitability and shareholder value in Germany. We analyse panel data of 115 firms listed on the German Prime Standard, covering the period from 2011 to 2017. The results provide evidence that efficient working capital management, indicated by a shorter cash conversion cycle, deteriorated over time, but that a shorter cash conversion has a positive impact on profitability and shareholder value. The findings highlight the need that managers should give greater priority to working capital optimization, even in a low-interest environment. The paper contributes to the literature by advancing this research area in Germany, and it is the first study investigating shareholder relationship with working capital management and all its determinants.
On the design of an urban data and modeling platform and its application to urban district analyses
(2020)
An integrated urban platform is the essential software infrastructure for smart, sustainable and resilitent city planning, operation and maintenance. Today such platforms are mostly designed to handle and analyze large and heterogeneous urban data sets from very different domains. Modeling and optimization functionalities are usually not part of the software concepts. However, such functionalities are considered crucial by the authors to develop transformation scenarios and to optimized smart city operation. An urban platform needs to handle multiple scales in the time and spatial domain, ranging from long term population and land use change to hourly or sub-hourly matching of renewable energy supply and urban energy demand.
Automatic classification of rotating machinery defects using Machine Learning (ML) algorithms
(2020)
Electric machines and motors have been the subject of enormous development. New concepts in design and control allow expanding their applications in different fields. The vast amount of data have been collected almost in any domain of interest. They can be static; that is to say, they represent real-world processes at a fixed point of time. Vibration analysis and vibration monitoring, including how to detect and monitor anomalies in vibration data are widely used techniques for predictive maintenance in high-speed rotating machines. However, accurately identifying the presence of a bearing fault can be challenging in practice, especially when the failure is still at its incipient stage, and the signal-to-noise ratio of the monitored signal is small. The main objective of this work is to design a system that will analyze the vibration signals of a rotating machine, based on recorded data from sensors, in the time/frequency domain. As a consequence of such substantial interest, there has been a dramatic increase of interest in applying Machine Learning (ML) algorithms to this task. An ML system will be used to classify and detect abnormal behavior and recognize the different levels of machine operation modes. The proposed solution can be deployed as predictive maintenance for Industry 4.0.
Power line communications (PLC) reuse the existing power-grid infrastructure for the transmission of data signals. As power line the communication technology does not require a dedicated network setup, it can be used to connect a multitude of sensors and Internet of Things (IoT) devices. Those IoT devices could be deployed in homes, streets, or industrial environments for sensing and to control related applications. The key challenge faced by future IoT-oriented narrowband PLC networks is to provide a high quality of service (QoS). In fact, the power line channel has been traditionally considered too hostile. Combined with the fact that spectrum is a scarce resource and interference from other users, this requirement calls for means to increase spectral efficiency radically and to improve link reliability. However, the research activities carried out in the last decade have shown that it is a suitable technology for a large number of applications. Motivated by the relevant impact of PLC on IoT, this paper proposed a cooperative spectrum allocation in IoT-oriented narrowband PLC networks using an iterative water-filling algorithm.
Our paper gives first answers on a fundamental question: how can the design of architectures of intelligent digital systems and services be accomplished methodologically? Intelligent systems and services are the goals of many current digitalization efforts today and part of massive digital transformation efforts based on digital technologies. Digital systems and services are the foundation of digital platforms and ecosystems. Digtalization disrupts existing businesses, technologies, and economies and promotes the architecture of open environments. This has a strong impact on new value-added opportunities and the development of intelligent digital systems and services. Digital technologies such as artificial intelligence, the Internet of Things, services computing, cloud computing, big data with analytics, mobile systems, and social enterprise networks systems are important enablers of digitalization. The current publication presents our research on the architecture of intelligent digital ecosystems and products and services influenced by the service-dominant logic. We present original methodological extensions and a new reference model for digital architectures with an integral service and value perspective to model intelligent systems and services that effectively align digital strategies and architectures with artificial intelligence as main elements to support intelligent digitalization.
his book highlights new trends and challenges in intelligent systems, which play an important part in the digital transformation of many areas of science and practice. It includes papers offering a deeper understanding of the human-centred perspective on artificial intelligence, of intelligent value co-creation, ethics, value-oriented digital models, transparency, and intelligent digital architectures and engineering to support digital services and intelligent systems, the transformation of structures in digital businesses and intelligent systems based on human practices, as well as the study of interaction and the co-adaptation of humans and systems. All papers were originally presented at the International KES Conference on Human Centred Intelligent Systems 2020 (KES HCIS 2020), held on June 17–19, 2020, in Split, Croatia.
Service Blueprinting
(2020)
Ein Ansatz des Dienstleistungsmanagements, mit dessen Hilfe Gesundheitsleistungen ganz aus Perspektive der behandelten Person und ihrer Customer Journey durch den Leistungsprozess analysiert werden kann, ist das sogenannte Service Blueprinting. Die vorliegende Fallstudie beginnt mit einer kurzen Einführung zur Begründung und zum Vorgehen dieses Ansatzes. Im Anschluss wird der Ansatz anhand der holprigen Customer Journey des imaginären Patienten Torben Schulz im Rahmen einer Bandscheiben-Operation kritisch diskutiert und auf einen Teilaspekt dieser Dienstleistung angewendet.
Die klassischen Vertriebsaufgaben verändern sich intensiv und schnell. Vertriebsmanager benötigen dringend neue strategische Ansätze, wie sie künftig Kundenkontakte gestalten, Distributionskanäle steuern und effektiver verkaufen können. Eine aktuelle Studie gibt Aufschluss, wie sich Unternehmen auf den Strukturwandel einstellen können.
Dieser Beitrag analysiert die Reform der IFRS und US-GAAP-Standards zur Bilanzierung von Leasingverhältnissen. Am Beispiel der McKesson Europe AG werden die Auswirkungen der erstmaligen Anwendung der Standards beim Leasingnehmer veranschaulicht. Von besonderem Interesse ist dabei ein Vergleich der Bilanzierungsmodelle nach den "alten" Standards IAS 17 und ASC 840 bzw. nach den "neuen" Standards IFRS 16 und ASC 842. Im Ergebnis zeigt sich keine vollständige Übereinstimmung von IFRS und US-GAAP. Vor allem beim Ausweis in der Gewinn- und Verlustrechnung ergeben sich Unterschiede, die sich auch auf die Ergebniskennzahlen auswirken.
Monday is unique for its reputation as a “bad” day—one that is characterized by pessimism and reluctance as noted by Rystrom and Benson (Financ Anal J 45(5):75–78, 1989). But the extent to which this applies to stock markets is still in dispute. While early evidence points to a Monday effect leading to negative returns, recent studies tend to suggest its disappearance or reversal.As a replication study, this paper searches for new evidence of this effect in the German stock market.We use data on the German blue-chip index DAX between 2000 and 2017 to test for the presence of a Monday effect by applying regression and controlling with GARCH analysis. The observation period provides a detailed insight into different market phases in one of the most liquid and information efficient international stock markets. Our results contribute no evidence to the persistent existence of a Monday effect on the German stock market. Our analysis is robust against the background of different market sentiments before, during and after the financial crisis.
The SDGs give an overview of the world's development challenges of the present and the coming decades and set a new global agenda for more inclusive and sustainable development and growth. These challenges also represent opportunities for social innovations and the creation of scalable and financially self-sustaining solutions by businesses and (social) entrepreneurs. Examples of solutions to social and ecological challenges are for instance providing low-income communities with access to affordable, quality products and services in areas such as water and sanitation, energy, health, education and finance. New business models can meet customer demands by providing solutions and thereby create opportunities for low-income people as employees, suppliers and distributors.
