Enterprises are currently transforming their strategy, processes, and their information systems to extend their degree of digitalization. The potential of the Internet and related digital technologies, like Internet of Things, services computing, cloud computing, artificial intelligence, big data with analytics, mobile systems, collaboration networks, and cyber physical systems both drives and enables new business designs. Digitalization deeply disrupts existing businesses, technologies and economies and fosters the architecture of digital environments with many rather small and distributed structures. This has a strong impact for new value producing opportunities and architecting digital services and products guiding their design through exploiting a Service-Dominant Logic. The main result of the book chapter extends methods for integral digital strategies with value-oriented models for digital products and services which are defined in the framework of a multi-perspective digital enterprise architecture reference model.
Unternehmen sind derzeit dabei, ihre Strategie, ihre Prozesse und ihre Informationssysteme zu verändern, um ihren Digitalisierungsgrad zu erhöhen. Das Potenzial des Internets und verwandter digitaler Technologien wie Internet der Dinge, Services Computing, Cloud Computing, künstliche Intelligenz, Big Data mit Analysen, mobile Systeme, Kollaborationsnetzwerke und cyber-physikalische Systeme treibt neue Geschäftsmodelle an und ermöglicht sie. Die Digitalisierung führt zu einer tiefgreifenden Umwälzung bestehender Unternehmen, Technologien und Volkswirtschaften und fördert die Architektur digitaler Umgebungen mit vielen eher kleinen und verteilten Strukturen. Dies hat starke Auswirkungen auf neue Wertschöpfungsmöglichkeiten und die Gestaltung digitaler Dienste und Produkte, die durch die Nutzung einer service-dominanten Logik gesteuert werden. Das Hauptergebnis des Buchkapitels erweitert Methoden für integrale digitale Strategien um wertorientierte Modelle für digitale Produkte und Dienstleistungen, die im Rahmen eines multiperspektivischen digitalen Unternehmensarchitektur-Referenzmodells definiert werden.
The digital transformation of our society changes the way we live, work, learn, communicate, and collaborate. The digitization of software-intensive products and services is enabled basically by four megatrends: Cloud computing, big data mobile systems, and social technologies. This disruptive change interacts with all information processes and systems that are important business enablers for the current digital transformation. The internet of things, social collaboration systems for adaptive case management, mobility systems and services for big data in cloud services environments are emerging to support intelligent user-centered and social community systems. Modern enterprises see themselves confronted with an ever growing design space to engineer business models of the future as well as their IT support, respectively. The decision analytics in this field becomes increasingly complex and decision support, particularly for the development and evolution of sustainable enterprise architectures (EA), is duly needed. With the advent of intelligent user-centered and social community systems, the challenging decision processes can be supported in more flexible and intuitive ways. Tapping into these systems and techniques, the engineers and managers of the enterprise architecture become part of a viable enterprise, i.e. a resilient and continuously evolving system that develops innovative business models.
This chapter presents an introduction to the emerging trends for architecting the digital transformation having a strong focus on digital products, intelligent services, and related systems together with methods, models and architectures. The primary aim of this book is to highlight some of the most recent research results in the field. We are providing a focused set of brief descriptions of the chapters included in the book.
In diesem Kapitel wird eine Einführung in die sich abzeichnenden Trends bei der Gestaltung der digitalen Transformation gegeben, wobei der Schwerpunkt auf digitalen Produkten, intelligenten Diensten und damit verbundenen Systemen sowie auf Methoden, Modellen und Architekturen liegt. Das primäre Ziel dieses Buches ist es, einige der neuesten Forschungsergebnisse auf diesem Gebiet hervorzuheben. Wir stellen eine Reihe von Kurzbeschreibungen der im Buch enthaltenen Kapitel zur Verfügung.
Besides the optimisation of the car, energy-efficiency and safety can also be increased by optimising the driving behaviour. Based on this fact, a driving system is in development whose goal is to educate the driver in energy efficient and safe driving. It monitors the driver, the car and the environment and gives energy-efficiency and safety relevant recommendations. However, the driving system tries not to distract or bother the driver by giving recommendations for example during stressful driving situations or when the driver is not interested in that recommendation. Therefore, the driving system monitors the stress level of the driver as well as the reaction of the driver to a given recommendation and decideswhether to give a recommendation or not. This allows to suppress recommendations when needed and, thus, to increase the road safety and the user acceptance of
the driving system.
This review gives a short overview of the physical processes involved in the formation of the polyelectrolyte multilayers (PEMs) and their destruction. These two processes are vital for the formation of PEMs with desired physical and chemical structures, and for loading them with active substances and their spatial controlled release. It includes a survey of the physical and chemical properties that are key points for controlling film nanostructure in relation to biological processes and different possibilities for controlling cell behavior by means of film composition, bioactivity, mechanical properties, and three-dimensional organization.
Die Coronapandemie hat Deutschland seit dem Frühjahr 2020 fest im Griff. Eine zentrale Maßnahme zur Verlangsamung der Ausbreitung des Coronavirus war von Beginn an die Schließung von Schulen. In einer ersten Studie wurden die Lernzeitverluste durch die Corona-bedingten Schulschließungen im Frühjahr 2020 quantifiziert (Wößmann, Freundl, Lergetporer, Grewenig, Werner & Zierow, 2020). Es zeigte sich, dass sich die Lernzeit der Schülerinnen und Schüler durch die Schulschließungen halbiert hatte und die Verluste bei leistungsschwächeren Schülerinnen und Schülern besonders groß waren. Im Frühjahr 2020 wurde die Verringerung der Lernzeit von den Schulen nicht kompensiert: Nur ein kleiner Teil der Schülerinnen und Schüler hatte in dieser Phase regelmäßigen Distanzunterricht und täglichen Kontakt mit Lehrkräften. Während der Sommer- und Herbstmonate seit der Phase der ersten Schulschließungen hatten Schulverwaltung, Schulen und Lehrkräfte Zeit, sich auf Distanzunterricht und digitale Lehrmethoden umzustellen, um Lernausfällen während etwaiger erneuter Schulschließungen entgegenzuwirken. Inwiefern dies dazu geführt hat, dass die Schülerinnen und Schüler während der Schulschließungen Anfang 2021 tatsächlich mehr Zeit mit Lernen verbracht haben als im Frühjahr 2020, ist jedoch bislang weitgehend unbekannt.
Um zu erfahren, mit welchen Aktivitäten die Schulkinder die Zeit der Schulschließungen Anfang 2021 verbracht haben, wurde erneut eine deutschlandweite Umfrage durchgeführt, diesmal unter mehr als 2.000 Eltern von Schulkindern. Die Ergebnisse liefern umfassende Einblicke in den Alltag von Schulkindern, Eltern und Schulen während der Schulschließungen Anfang 2021. Sie zeigen, wie viele Stunden die Schulkinder in dieser Phase mit Lernen und anderen kreativen und passiven Tätigkeiten verbracht haben, welche konkreten Maßnahmen die Schulen ergriffen haben, um den Schulbetrieb aufrechtzuerhalten, wie effektiv das Lernen zu Hause war, und wie die Eltern das häusliche Lernumfeld einschätzen. Dabei vergleichen wir die Aktivitäten während der Schulschließungen Anfang 2021 mit den Aktivitäten während der ersten Corona-bedingten Schulschließungen im Frühjahr 2020 sowie mit den Aktivitäten vor Corona (vgl. Wößmann et al., 2020). Wir berichten zudem Ergebnisse zum sozio-emotionalen Wohlbefinden der Kinder nach einem Jahr Coronapandemie und zu den Einschätzungen der Eltern, welche breiteren Auswirkungen die Schulschließungen auf verschiedene Lebensbereiche ihrer Kinder haben. Die Befragung liefert somit neue empirische Erkenntnisse über mögliche Folgen der Corona-Krise für den Bildungserfolg von Kindern in Deutschland. Dabei untersuchen wir auch, inwiefern sich die Auswirkungen der Schulschließungen zwischen leistungsstärkeren und -schwächeren Schülerinnen und Schülern sowie zwischen Akademikerkindern und Nicht-Akademikerkindern unterscheiden.
CODE RED FOR HUMANITY. The alarm bells are deafening, and the evidence is irrefutable: greenhouse-gas emissions from fossil-fuel burning and deforestation are choking our planet and putting billions of people at immediate risk. Global heating is affecting every region on Earth, with many of the changes becoming irreversible. (Guterres 2021)
The digitalisation ongoing in households and sustainability-related challenges are multifaceted and complex. The introducing quote of the United Nations Secretary-General refers to the latest report of the Intergovernmental Panel on Climate Change (IPCC), emphasising the urgency to act – now. As of today, becoming a sustainable population is still a distant destination. As outlined in the previous chapters, the challenges associated with that transformation remain huge, complex, and largely unsolved. Recent dramas such as the power incident in Texas (2021), the floods in Germany (2021), or the drought in sub-Saharan Africa (2020s) – are just a few of the uncountable issues stirring up the debate about fossil-fuel abandonment and the timing of climate neutrality. Business research can actually be accused of referring to the persistent focus on gains and growth, despite early warnings for society at large (e.g., Meadows et al., 1972; Kölsch & Veit, 1981; Veit & Thatcher, 2023). However, academic researchers, corporations, and society are now waking up, as shown by the climate change conference. In fact, it appears that the information systems (IS) discipline just began tackling mammoth challenges around climate change within the last decade (Melville, 2010; Watson et al., 2010). The central discussion in emerging work revolves around the role and use of digital technologies on the path to a healthy planet. But while early studies have focused on organisational settings (e.g., Gholami et al., 2016; Seidel et al., 2013), increasingly research addresses private settings (e.g., Wunderlich et al., 2019).
The evolution of Services Oriented Architectures (SOA) presents many challenges due to their complex, dynamic and heterogeneous nature. We describe how SOA design principles can facilitate SOA evolvability and examine several approaches to support SOA evolution. SOA evolution approaches can be classified based on the level of granularity they address, namely, service code level, service interaction level and model level. We also discuss emerging trends, such as microservices and knowledge-based support, which can enhance the evolution of future SOA systems.

Findings: The integraton of the customer into the marketing mix is inevitable in today's marketplace. Customers are heavily influencing the fashion industry escpecially the transmission of trends. Thereof, a redefinition and proactive integration of the customer as promoter is necessary.
This article covers the design of highly integrated gate drivers and level shifters for high-speed, high power efficiency and dv/dt robustness with focus on automotive applications. With the introduction of the 48 V board net in addition to the conventional 12 V battery, there is an increasing need for fast switching integrated gate drivers in the voltage range of 50 V and above. State-of-the-art drivers are able to switch 50 V in less than 5 ns. The high-voltage electrical drive train demands for galvanic isolated and highly integrated gate drivers. A gate driver with bidirectional signal transmission with a 1 MBit/s amplitude modulation, 10/20 MHz frequency modulation and power transfer over one single transformer will be discussed. The concept of high-voltage charge storing enables an area-efficient fully integrated bootstrapping supply with 70 % less area consumption. EMC is a major concern in automotive. Gate drivers with slope control optimize EMC while maintaining good switching efficiency. A current mode gate driver, which can change its drive current within 10 ns, results in 20 dBuV lower emissions between 7 and 60 MHz and 52 % lower switching loss compared to a conventional constant current gate driver.

Natural wood colors occur within a wide range from almost white (e.g., white poplar), various yellowish, reddish, and brownish hues to almost black (e.g., ebony). The intrinsic color of wood is basically defined by its chemical composition. However, other factors such as specific anatomical formations or physical properties further affect the optical impression. Starting with the chemical composition of wood and anatomical basics, wood color and its modifications are discussed in this chapter. The classic method of coloring or re-coloring wood-based material surfaces is the application of a coating containing appropriate dyes or pigments. Different concepts for wood coating and coloration are presented. Another method used dyes for coloration of the wood structure. As alternative techniques, physical methods, for example, drying, steaming, ammoniation, bleaching, enzyme treatment, as well as treatment with electromagnetic irradiation (e.g., UV), are explained in this chapter.
A lot of people need help in their daily life to wash, select and manage their clothing. The goal of this work is to design an assistant system (eKlarA) to support the user by giving recommendations to choose the clothing combinations, to find the clothing and to wash the clothing. The idea behind eKlarA is to generate a system that uses sensors to identify the clothing and their state in the clothing cycle. The clothing cycle consists of the stations: closets, laundry basket and washing machine in one or several places. The system uses the information about the clothing, weather and calendar to support the user in the different steps of the clothing cycle. The first prototype of this system has been developed and tested. The test results are presented in this work.

Software scripts for sensor data extraction in Rasberry Pi: user-space and kernel-space comparison
(2024)
This paper compares two popular scripting implementations for hardware prototyping: Python scripts execut from User-Space and C-based Linux-Driver processes executed from Kernel-Space, which can provide information to researchers when considering one or another in their implementations. Conclusions exhibit that deploying software scripts in the kernel space makes it possible to grant a certain quality of sensor information using a Raspberry Pi without the need for advanced real-time operational systems.
Trotz der oft schwierigen Rahmenbedingungen auf den Märkten Subsahara Afrikas ist es möglich, ein erfolgreiches Geschäft aufzubauen, sofern man die adäquate Markteintrittsform wählt und darüber hinaus bereit ist, das eigene Geschäftsmodell an die lokalen Gegebenheiten anzupassen. Eine Herausforderung ist die politische, wirtschaftliche und kulturelle Heterogenität in Subsahara Afrika, die es unmöglich macht, den Kontinent als einen Markt zu bearbeiten. Allerdings gibt es seit Jahrzehnten regionale Integrationsabkommen, die jedoch erst in den letzten Jahren wiederbelebt und vorangetrieben wurden, wie z. B. die ECOWAS (Economic Community of West African States), die EAC (East African Community) und die SADC (South African Development Corporation). Inzwischen funktionieren diese Initiativen soweit, dass einige ausländische Unternehmen beginnen, Teile des Geschäftes regional und nicht mehr national zu organisieren, also die Länder als gemeinsamen Markt zu bearbeiten. In der Regel sind die kulturellen Unterschiede in Nachbarländern nicht so groß. Aus diesen Gründen besteht Wachstumspotential für geschäftlich interessante Märkte in Subsahara Afrika.
Afrika ist aufgrund überdurchschnittlicher Wirtschaftswachstumsraten und als die weltweit letzten unbearbeiteten Märkte seit einigen Jahren ein populäres Thema der Wirtschaft. Deutsche Unternehmen sind allerdings mit ihrem Engagement auf den afrikanischen Märkten sehr zurückhaltend. So schwankt der Anteil der deutschen Exporte nach Afrika an den deutschen Gesamtexporten seit zehn Jahren um die zwei Prozent; betrachtet man nur Subsahara‐Afrika, so waren es sogar nur 0,5 % in 2014 (Allafi und Koch 2015, S. 3). Bezüglich der Direktinvestitionen (nur Beteiligungskapital, ohne Direktinvestitionskredite) spielt Afrika eine noch geringere Rolle mit nur 1,5 % aller deutschen Investitionen in 2014, wobei hiervon so gut wie alle nach Nordafrika und Südafrika geflossen sind (Deutsche Bundesbank 2015, S. 12 f.). Neben den Standardgründen wie beispielsweise politischen Risiken, schlechter Infrastruktur, schwacher institutioneller Rahmenbedingungen und Governance‐Problemen (vgl. zum Beispiel World Bank 2016a), ist ein gängiges Markteintrittsproblem die fehlende Verfügbarkeit von lokalen Partnern in den Bereichen Vertrieb, Logistik und teilweise auch Produktion (vgl. zum Beispiel Carlowitz und Röndigs 2016). Aktuell ist ein Markteintritt in Afrika ohne lokalen Partner aufgrund der völlig anderen und schwierigen Rahmenbedingungen fast unmöglich.
Unternehmertum spielt sowohl für die Entwicklung afrikanischer Länder eine Rolle, als auch für ausländische Unternehmen mit Markteintrittsplänen. Die infrastrukturellen und institutionellen Rahmenbedingungen für Unternehmertum sind nach wie vor schwierig, wobei aber die fortschreitende Digitalisierung zu einer zunehmend aktiven Start-Up Szene in vielen afrikanischen Ländern führt. Nach wie vor existiert ein Mismatch zwischen den Bereichen in denen Start-Ups entstehen und den Bereichen, wo ausländische Unternehmen Partner für den Markteintritt suchen. Somit bleibt es trotz positiver Entwicklung beim Unternehmertum in absehbarer Zeit schwierig adäquate Partner zu finden.
Entrepreneurship plays a role both for the development of African countries and for foreign companies with market entry plans. The infrastructural and institutional conditions for entrepreneurship are still difficult, but the advancing digitization leads to an increasingly active start-up scene in many African countries. There is still a mismatch between the areas where start-ups are created and the areas where foreign companies are looking for partners for market entry. Thus, despite positive developments in entrepreneurship, it remains difficult to find suitable partners in the foreseeable future.
Rapidly growing data volumes push today's analytical systems close to the feasible processing limit. Massive parallelism is one possible solution to reduce the computational time of analytical algorithms. However, data transfer becomes a significant bottleneck since it blocks system resources moving data-to-code. Technological advances allow to economically place compute units close to storage and perform data processing operations close to data, minimizing data transfers and increasing scalability. Hence the principle of Near Data Processing (NDP) and the shift towards code-to-data. In the present paper we claim that the development of NDP-system architectures becomes an inevitable task in the future. Analytical DBMS like HPE Vertica have multiple points of impact with major advantages which are presented within this paper.
Higher education institutions (HEIs) rely heavily on information technology (IT) to create innovations. Therefore, IT governance (ITG) is essential for education activities, particularly during the ongoing COVID-19 pandemic. However, the traditional concept of ITG is not fully equipped to deal with the current changes occurring in the digital age. Today's ITG requires an agile approach that can respond to disruptions in the HEI environment. Consequently, universities increasingly need to adopt agile strategies to ensure superior performance. This research proposes a conceptualization comprising three agile dimensions within the ITG construct: structures, processes, and relational mechanisms. An extensive qualitative evaluation of industry uncovered 46 agile governance mechanisms. Moreover, 16 professors rated these elements to assess agile ITG in their HEIs to determine those most effective for HEIs. This led to the identification of four structure elements, seven processes, and seven relational mechanisms.
Die Internationalität muss das Markenzeichen und ein wesentlicher Bestandteil des Leitbildes einer Hochschule sein. Für die Strategieentwicklung und -umsetzung bedarf es der notwendigen Strukturen an einer Hochschule sowie der Vernetzung mit weiteren nationalen und internationalen Partnern. Keine Hochschulleitung würde dieses Erfordernis in Zweifel ziehen. Und doch unterschätzen noch immer Rektorate und Präsidien diesen "Dauer-Marathon". Eine Internationalisierungsstrategie wird vielfach und damit gleichzeitig unkorrekt mit einem Perpetuum mobile
verglichen. Einmal verabschiedet, geht es weiter - es gibt keinen Stillstand. Aber das passendere Bild - auch für die Hochschule Reutlingen - ist die Strategie, die einem "kontinuierlichen Verbesserungsprozess" gleicht.
Since the beginning of the energy sector liberalization, the design of energy markets has become a prominent field of research. Markets nowadays facilitate efficient resource allocation in many fields of energy system operation, such as plant dispatch, control reserve provisioning, delimitation of related carbon emissions, grid congestion management, and, more recently, smart grid concepts and local energy trading. Therefore, good market designs play an important role in enabling the energy transition toward a more sustainable energy supply for all. In this chapter, we retrace how market engineering shaped the development of energy markets and how the research focus shifted from national wholesale markets to more decentralized and location-sensitive concepts.
Lehre und Lernen unterliegt einem stetigen Wandel, wobei Interaktion als ein zentrales Element der Motivationssteigerung im Lernkontext angesehen wird. Der vorliegende Beitrag zeigt verschiedene Ansätze zur Gestaltung von interaktivem und kollaborativem Lehren und Lernen in einem virtuellen Klassenzimmer auf und stellt ein Beispiel für die Umsetzung und den Einsatz eines solchen Systems vor. Die Mehrwerte und Erfolgsfaktoren, die sich beim Einsatz virtueller Klassenzimmer und deren Gestaltung in Form einer interaktiven blended-learning Umgebung ergeben, werden dargestellt und diskutiert. Mit dem System Accelerator wird eine CSILT (Computer Supported Interactive Learning and Teaching)-Umgebung vorgestellt, in der diese Faktoren zum Einsatz kommen.
Der Erfolg des Resales in der Modebranche wird vor allem durch das starke Wachstum verdeutlicht, denn im Vergleich zum Retail wuchs dieser im vergangenen Jahr 24 Mal schneller. Eine aktuell aufstrebende Form des Verkaufs, Resale, bezeichnet den Prozess, den Produkte durchlaufen, wenn diese ein zweites Mal verkauft, das heißt aus zweiter Hand wiederverkauft werden. Retail hingegen beschreibt den traditionellen Verkauf von Produkten über den (stationären) Einzelhandel. Es kehren also immer mehr Produkte, welche bereits im Besitz eines anderen gewesen sind, in den Handel zurück und stehen erneut zum Verkauf bereit. Womit diese Aufwärtsentwicklung in der Modebranche ermittelt werden kann und inwiefern der Resale auf den Retail trifft, wird im Folgenden beschrieben.
Allyls
(2014)
This chapter addresses the importance and usage of the commercially low volume thermoset plastics group known as allyls. The three significant sub-elements of this group are poly(diallylphthalates), poly(diallylisophthalates), and poly(allyldiglycol carbonate). Chemistry, processing, and properties are also described. Allyl polymers are synthesized by radical polymerizations of allyl monomers that usually do not produce high-molecular-mass macromolecules. Therefore, only a few specific monomers can produce thermosetting materials. Diallyldiglycolcarbonate (CR-39) and diallylphthalates are the most significant examples that have considerably improved our everyday life.

Automated stabilization of loading capacity of coal shearer screw with controlled cutting drive
(2015)
A solution of topical scientific problem of coal shearer output increase providing minimum specific power supply for coal cutting, transportation, and loading in terms of thin seams has been proposed. The solution is based on the use of earlier proposed criterion of screw gumming for optimum cutting velocity-coal shearer feed rate ratio in the context of increased screw rotation owing to phase voltage frequency increase. Simulation results of automated control system for coal shearer operations with frequency-controlled cutting drive within thin seams have confirmed the efficiency of the system using proposed algorithm of smart analysis of coal shearer power signal.
In digital transformierten Arbeitswelten organisieren die Mitarbeitenden ihre Arbeitszeit, ihren Arbeitsort und die Art und Weise, wie sie Aufgaben erledigen, in größerem Umfang selbst. Unternehmen, die im Zuge des Transformationsprozesses den Grad der Selbstorganisation erhöhen möchten, stehen vor einer komplexen Herausforderung. Selbstorganisation betrifft zahlreiche Elemente der Organisation wie Arbeitsaufgaben und Rollen, Führung, Regeln und Kompetenzen. Auf Basis eines empirisch entwickelten Bezugsrahmens, dem Digitalisierungsatlas, können die verschiedenen Elemente integrativ betrachtet und die Wechselwirkungen zwischen den Dimensionen in den Blick genommen werden. Wird Selbstorganisation ausgehend von der Autonomie der Beschäftigten, Arbeitsaufgaben und die eigene Rolle in der Organisation selbst zu beeinflussen, in den Blick genommen, sind insbesondere die Wechselwirkungen zwischen den organisationalen Dimensionen sowie Führung relevant. Die Spannungen zwischen diesen Dimensionen werden näher fokussiert. Insgesamt zeigt der Beitrag auf, dass Selbstorganisation nicht als ein unabhängiges Phänomen verstanden werden kann, sondern stets in Wechselwirkung mit anderen Dimensionen steht.
Wenn Unternehmen den Schritt in die digitale Arbeitswelt gehen wollen, stehen sie vor der Herausforderung, konkrete Vorstellungen, Ziele und Maßnahmen zu entwickeln und umzusetzen. Häufig fehlt es Unternehmen an Wissen, ihre Transformation der Arbeitswelt strategisch zu gestalten und zu planen. Das Projekt DigiTraIn 4.0 setzt hier an und bietet mit dem Digitalisierungskompass ein Instrument, welches Unternehmen dabei unterstützt, eine Vision und spezifische Ziele für die Digitalisierung ihrer eigenen Arbeitswelt zu entwickeln. Im Anschluss daran unterstützt die Transformationsagenda Unternehmen dabei, konkrete Handlungsmaßnahmen zu entwickeln und deren Ablauf zu planen.
Die Verwaltung tritt uns als altruistische Institution gegenüber: Sie dient in der Regel nicht sich selbst, sie ist kein "Selbstzweck", sondern verfolgt regelmäßig andere, meist übergeordnete Ziele. Als der ausführende Arm der Politik soll sie deren politische Zwecke umsetzen, gleichzeitig aber, so zumindest in modernen, rechtsstaatlich organisierten Demokratien und unter dem Stichwort "public governance" Recht und Gesetz achten sowie Gemeinwohlinteressen wie Nachhaltigkeit und/oder soziale Gerechtigkeit durchsetzen.
Die Verwaltung ist über die Zuordnung zu den Systemen Recht und Politik hinaus in weitere soziale Funktionssysteme eingebunden. Sofern es sich z.B. um Verwaltung in Wissenschaft und Forschung handelt, wird sie sich mit dem Code und dem Kommunikationsmedium der Wissenschaft konfrontiert sehen. Die Wirtschaftsverwaltung muss sich dem binären Code "Zahlung/keine Zahlung" der Wirtschaft stellen.
Dieser Ausgleich zwischen den Systemen macht es notwendig, dass ethisch-moralische Werte in den Dilemma-Situationen in die Entscheidungsfindung einbezogen werden. Die entscheidende Orientierung liefern dabei die materialen Werte der Tugendethik. Der Mitarbeiter der Verwaltung darf sich in gravierenden Konfliktsituationen den Anforderungen der Tugendethik nicht entziehen, sondern muss sein Handeln an Hand ihrer Werte überprüfen. Im Ergebnis führt dieses Verfahren zu einem harmonischen Ausgleich zwischen der Systemtheorie und werteorientierten Ansätzen.
Eine der Hauptaufgaben der Ethik als wissenschaftlicher Disziplin ist es, dem Menschen Entscheidungshilfen für Situationen zu geben, in denen jede denkbare Handlungsalternative Vor- und/oder Nachteile hat, die ohne Weiteres nicht gegeneinander abgewogen werden können. Diese Situation wird als "Dilemma" bezeichnet.
Dilemma-Situationen treten immer dann auf, wenn sich die moralisch-ethische Bewertung einer Situation von der Bewertung unterscheidet, die durch korrekte Anwendung der gesetzlichen Grundlagen vorgeschrieben wird. Menschen in der Verwaltung sind daher in besonderem Maße der Gefahr von Zielkonflikten ausgesetzt.
Textil im Verbund ist besser? Das ist in der Fachwelt lange keine Frage mehr, textile Verbundwerkstoffe können viele Vorteile bieten. Es ist wohl bekannt, dass sie oft besser sind als nicht-textile Alternativen. Die Beispiele sind mannigfaltig. Innovative Entwicklungen sind nicht nur der stark beachtete Textilbeton, der mit dem Deutschen Zukunftspreis ausgezeichnet wurde, sondern auch viele vielleicht weniger wahrgenommene oder spektakuläre Produkte auf Basis faserverstärkter Kunststoffe.
Are textile structures better? In the professional world, there is no doubt that textile composites can offer many advantages. It is well known that they are often better than non-textile alternatives. There are manifold examples. Innovative developments are not only the popular textile reinforced concrete which was awarded with the Deutscher Zukunftspreis (German Future Award) but also a huge number of probably less perceived or spectacular products based on fiber-reinforced plastics.
Logistics has undergone tremendous changes over the past few decades. Above all with the advent of the digital age, we have witnessed the significant impact of new technologies on supply chains in terms of business transformation, increased agility and performance. However, many businesses have chosen to harness the full potential of these technologies to create further value (Bughin et al, 2017). High investment costs, fears for cyber security, a lack of expertise in the workforce and insufficient awareness of the concrete benefits of these technologies are just some of the factors hampering the decision to adopt digital technologies.
The following chapter draws on the findings of both recent quantitative and qualitative research conducted by practitioners und academics.
Unternehmen arbeiten in Netzwerken mit vielfältigen Lieferanten- und Kundenbeziehungen und an unterschiedlichen Stellen der Wertschöpfungsketten. Dem Supply-Chain-Controlling kommt daher eine sehr hohe Bedeutung im Unternehmen zu. Es unterstützt das Management bei der Gestaltung und Steuerung unternehmensübergreifender Material-, Informations- und Geldflüsse. Dabei soll es die Effizienz und die Effektivität des unternehmerischen Handelns bzw. Entscheidens gewährleisten.
Case study: EMP
(2018)
The purpose of this research paper is to investigate the business model of the retailer EMP. The in-depth literature review develops the relevance of merchandising for the rock and heavy metal scene and the relevance of EMP within that market. Literature about existing approaches of multi-channelling has been reviewed. Based on this theoretical framework, a case study of EMP has been drafted. Findings are discussed, focusing on the performance of EMP as a multi-channel and lifestyle retailer and additionally provide valuable managerial implications for fashion retailers. Implications for further research address lifestyle retailers to contribute to the findings or validate them with different examples. The research is clearly limited by the amount of scholar literature concerning EMP in particular. Hence, magazines, journals and information provided by the company serve as reference. Even though EMP provided some information, gathering any information about how EMP manages multi channelling operationally was not possible.
Co-design and endorsement
(2018)
The purpose of this paper is to determine the success factors regarding celebrities of the music business involved in fashion advertising. That famous people have the power to help brands and products to stand out among others is proven and popular. This paper is concentrating on successful musicians and their endorsements of fashion brands and examines the benefits for both, the brand and the artist. It investigates how consumer perceives brand and artist collaboration and what factors enhance the purchase intention and increase sales. This paper is structured in the following manner: The introduction presents the research question and sets the aim for the paper, followed by the analysis of the existing literature. The paper ends with conclusions, limitations and suggestions for further research.
The purpose of this paper is to identify the potential of a fashion fTRACE (ffTRACE) application that gives transparent insight on the supply chain of a fashion item. The research methodology applied to this purpose is a literature review examining academic references. The key findings of this paper are that information plays a major role in the consumer decision process and is therefore beneficial to the demand for sustainable products. Given the right information content in a transparent, credible and understandable way is important. It is found that the functions of such an application would be able to satisfy this consumer demand and therefore has the potential to raise the sales of a sustainable company as well as increase the brand’s awareness and improve its image. While mainly indicating the potentials of the ffTRACE application, their relevance is not examined in this paper.
The purpose of this paper is to investigate the use of sustainable closed-loop supply chain of the fashion brand Filippa K. Information on green fashion has been gathered and a case study approach on the fashion retailer
Filippa K conducted. Results show a switch in knowledge content between a fast fashion supply chain and a sustainable supply chain. Also there is an evolution in sustainability as companies, retailers, and manufactures suffer under pressure from the customers, governments, and the media. Sustainable fashion brands like Filippa K are interested in sharing precise knowledge on variety of aspects linked to the sustainable closed-loop supply chain. This research paper has been limited by less information and unexplored topics in the theme green fashion. This led to the personal critical disputation with the brand Filippa K.
Aim of this paper is to provide an understanding to which extent music and fashion interdepend and interact referring to the music and fashion trend development, focusing the period from 1950 till today. It further helps the reader to gain an insight if the technology provided influences the development and the access of music and fashion in future. The research for this paper required the use of secondary sources including library and online research. The goal was to gather information about the former and current development of music and fashion. These methods were the best alternatives of secondary sources as they provided trusted results thus enhancing the accuracy of the data being collected. But however they were also limited since mainly data for the fashion and music development of the noughties were limited. This is explainable by the key finding that the development of this time is not as distinct as the one of the former times, when a fashion trend came along with a new music genre or hit, which implies that fashion and music correlate to a certain extent, but characterized by a reactivation of the music and fashion trends of previous times without any new inventions.
Das Ziel dieses Papiers ist es zu verstehen, inwieweit Musik und Mode voneinander abhängig und miteinander interagieren, wobei der Schwerpunkt auf der Entwicklung von Musik- und Modetrends im Zeitraum von 1950 bis heute liegt. Darüber hinaus soll dem Leser ein Einblick darin ermöglicht werden, ob die zur Verfügung stehende Technologie die Entwicklung und den Zugang zu Musik und Mode in Zukunft beeinflusst. Die Recherche für dieses Papier erforderte die Verwendung von Sekundärquellen, einschließlich Bibliotheks- und Online-Recherchen. Das Ziel war es, Informationen über die frühere und aktuelle Entwicklung von Musik und Mode zu sammeln. Diese Methoden waren die besten Alternativen zu Sekundärquellen, da sie zuverlässige Ergebnisse lieferten und so die Genauigkeit der gesammelten Daten erhöhten. Sie waren jedoch auch begrenzt, da vor allem Daten für die Mode- und Musikentwicklung der Nullerjahre begrenzt waren. Dies ist durch das Hauptergebnis erklärbar, dass die Entwicklung dieser Zeit nicht so deutlich ist wie die der früheren Zeiten, in denen ein Modetrend mit einem neuen Musikgenre oder Hit einherging, was bedeutet, dass Mode und Musik in gewissem Maße korrelieren, aber durch eine Reaktivierung der Musik- und Modetrends der Vorjahre ohne neue Erfindungen gekennzeichnet ist.
The purpose of this paper is to investigate how the practice of closed-loop production systems (CLPS) is implemented in the fashion industry. This paper offers a critical literature review to present a thorough understanding of the actual status of literature. Subsequently, the paper reveals that CLPS are of great importance. Generally, such systems include different activities that have to be integrated. Critical points are the product acquisition, the recovering process itself and the remarketing to the customer. A lack of reliable data concerning CLPS in the specific case of fashion industry can be identified. Important research fields could be marketing strategies, controlling the acquisition process, evolvement of return technologies and strategies, adaption of recovered products to the mass market, and the development of new technologies concerning recovering processes.
The purpose of this paper is to explain the key aspects and growing relevance of sustainability in fashion retail and to evaluate the possibilities of fashion retailers to act sustainable in supply chain management as well as carving out the challenges they have to deal with. The research methodology applied for this purpose is a critical literature review examining books and articles. The findings demonstrate the rising importance of sustainability in fashion retail. In this regard, fashion retailers play a key role and responsibility for sustainability in the fashion supply chain, from the beginning up to the end. This paper mainly analyzes sustainability in the fashion supply chain. It does not analyze topics like second-hand shopping or social media sustainability.
Since there is no denying that transparency is increasingly central to corporate sustainability, the purpose of this paper is a case study on a company’s attempt to be fully transparent, hence, picking up the existent scholarly conversation about uncompromising supply chain transparency. Literature so far was found to be fairly limited, but, following a trend, has been rising in numbers over recent years. Addressing these shortcomings in the methodology, an in-depth literature review about the multiple dimensions of supply chain transparency has been performed and links within supply networks stressed. On this basis, a case study by exemplary illustrating the fashion label Honestby has been drafted and the effort to become the world’s first 100 % transparent company further examined. Findings are discussed whether more supply chain transparency is desirable in any case, obstacles listed and an outlook for this kind of business model has been drawn. The research is clearly limited by the amount of scholarly literature concerning Honestby in particular. Out of this reason, magazines and journal entries are used as reference as well. Only with the extension of the topic itself to supply chain transparency and the literature review beforehand, the paper gained its necessary academic standard. Concerning implications, it needs to be mentioned that even though Honest by demonstrates to be fully transparent, it was not possible to find any public information about the degree of supplier relationship. In particular, concerning the applied control mechanisms used to exert influence and to balance out the power gradient between company and suppliers.
The purpose of this paper is to study the recycling form of reusing second hand clothing from a conventional fashion brand’s perspective. It should clarify which measures and activities a fashion company needs to integrate in its value chain in order to offer branded second hand merchandise in a self-operated store. The research paper relies on a desk-based research and aims to illustrate the topic by means of a descriptive approach, processing the existing literature. Key findings demonstrate that fashion brands need to integrate complete lifecycle strategies, sustainability communication, and reverse logistics structures, like take-back schemes, for offering second hand clothing. The main limitations evolve from the research design. Further, empirical evidences need to be conducted for a more fundamental understanding of the new business model.
The purpose of this paper is to identify key success factors of Crowdfunding in the Music Business in order to discuss their applicability to the Fashion Industry. The research methodology applied is a literature review examining academic and non-academic references. Key research findings include four main success factors. First explains the innovative and adaptive nature of the music industry caused by historical evolution. Second strong commitment and connection to the fan base is identified as success factor. Third manageable effort for the realisation on a large scale reduces the risk of a failure. And, last success factor describes the successful implementation of campaign specific aspects. The discussion finally shows that three of four success factors can be adapted to the Fashion Business. Due to little scientific research in the field of Crowdfunding in the Music Business, the success factors are worked out independently, based on general literature. Accordingly, quantitative testing and further analysis is recommended.
This article aims to point out main changes of the music industry since the advent of the Internet and how the fashion industry can learn from it. Different factors are researched with a birds-eye perspective by conducting a literature review. The results are limited by the availability of sources and the implications are based on a theoretical foundation. For further research the conclusions drawn for the fashion industry have to be proven empirically. After reading the paper, the reader has rather an overview of the changed circumstances and how the music industry reacted than deep knowledge in each field. More specifically, this paper gives an overview of the changed circumstances due to digitalisation and how the music industry reacted within. As both the fashion and music industry have their similarities, they are limited in their comparability, since fashion products cannot be fully digitalized like a music record. The fact that the music industry had to reinvent itself rapidly to adopt new possibilities and chances results from the article. To make use of the sustainability trend and to build communities in order to include them in the creation process are the major suggestions for the fashion industry.
Purpose of the present research paper is to examine the current state of research, define dimensions of research and reveal gaps in research on the topic of ‘Fashion and music’. To do so, the methodology of a scientific literature review was applied. The literature review revealed that music and its business mainly serve the fashion industry as influencer on trends, image building marketing tool, support of fashion processes and contributor to the development of innovative fashion products. Both industries provide identify-forming features, unify their mutual target groups in a certain lifestyle and thus enlarge their own target market. This results in increased brand awareness, image and credibility, emotionalized brand experience, differentiation and sophisticated brand identity. The present paper can serve as the basis for further research. It is limited by the time, depth and availability of data collection, the predominance of grey literature and its focus on the modern relationship of fashion and music.
The purpose of this paper is to define what impacts sustainable manufacturing standards have for retail brands concerning the communication policy and to find possible solutions of how the companies can deal with them. Therefore, sustainable standards and the impacts on the internal and external communication are described. The enclosed discussion finds possible solutions for the negative impacts. A literature discussion has been conducted to investigate the purpose. Generally, there are many impacts fashion retails have to consider, if they want to transform their company to become more sustainable, because only the impacts on a defined part of the communication policy were huge. A limitation of this paper is that the proposals how retailers could deal with the impacts of the transformation of the company toward more sustainability need further research and tests until they are practicable.
The second hand concept indicates a growing trend in clothing recently, leading to growing numbers of second hand shops and developments of new second hand retail forms. This paper concentrates on the current second hand market for fashion products and presents the different motives toward second hand consumption as well as alternative consumption channels for second hand products. The findings of the paper are founded on literature research of academic articles and case studies. Results show that there is a high potential for the second hand market due to the increasing interest of consumers in buying second hand products. The paper concentrates on the second hand market for fashion products in the western society. This means that there was no research on second hand products for disadvantaged people in poor countries. Furthermore, the paper focuses the formal second hand retail channels to see what is already on the market.
Music is omnipresent and an important factor for cultural and social development. Thus, the connection between music and fashion has rarely been contemplated yet. In particular, this research paper is concerned with the connection between music and fashion communication, with special interest to its emotional background in the context of neuromarketing. The research question of how music affects the perception of a fashion brand, when regarded as emotional stimulus in the context of neuromarketing, has been investigated by researching existing literature. Without attempting to explain neurological processes to their core, this paper tries to give an overview of how music generates emotion and how this can be used for branding activities. This led to the result that music causes positive emotional response of the consumer, when used in marketing actions. Through emotional response, the perception, identity, and recall of a brand are strongly influenced.
This paper is purposed to examine the impact of grunge music on fashion and to explain how grunge music is reflected in grunge style. The research methodology applied is a case study on grunge music and grunge style. Key findings suggest that different elements of grunge music had a great impact on the evolution of grunge style: Mentality and philosophy of the movement, musical style and sound as well as lyrical concerns are incorporated by grunge style. Commercial exploitation of grunge partly led to its downfall. Moreover, the original spirit of the movement is not commonly shared by all sub-genres’ respective contemporary styles. Musicians had great impact on the evolution of grunge style and unintentional rose to style icons. The research is limited by the amount of academic literature concerning the connection between grunge music and grunge style. Therefore, journal entries and blogs are used as reference as well.
The purpose of this research paper is to find out to which extent rap music merchandise is influencing the fashion world of today. The research design is mainly created through analysing Internet sources. The key findings of this paper describe the way rap merchandise is created and distributed nowadays. Furthermore, is explained how an idea becomes trend and how rap artists influence trend creation, especially through social media channels. The topic around rap merchandising products and strategies is a very new one, thus there is barely any literature to find. Nevertheless, trend leading online music platforms and blogs offer a lot of grey literature about the research topic. In this paper, the analysis of rap merchandise and fashion is focused on clothing items to create a better understanding in which dimension the influence of rap merchandise on the fashion world is given.
The purpose of this research is to explore current boundaries of the fashion industry’s second hand market and which solutions and approaches can be adopted from the used-car industry. The paper is based on the study of existing literature which deals with sustainability in combination with second hand markets in general and adaptable features of the used-car industry. Adaptable features are found using the business model canvas. The key finding of this study indicates that the fashion industry faces immense social and environmental challenges which can be partly solved by the development of the second hand market. Used-car industry can be seen as role model for fashion retail. In this study only aspects of used-car distribution are highlighted; therefore, characteristics of the recycling of used cars are not examined.
The purpose of this paper is to identify the role of in-store music in the fashion retail environment and to describe music as an atmospheric building tool in order to influence customer behaviour with emotions created by musical compositions. As offline retailer try to differentiate their stores through shopping experiences, atmospherics like visuals, scent and sound are appropriate tools to reinforce brand image and therefore customers’ willingness to enter, explore and purchase. Music can be a powerful primary element in creating or enhancing sensory experiences of shoppers and serves as a powerful connection to emotions. Focus of the literature review lies on the emotions which are triggered though different musical characteristics and then affect the customer behaviour. The paper offers a concisely presented review and highlights crucial aspects on what role in-store music has on customers’ perception of atmosphere, emotions and behaviour.
The purpose of this paper is to examine the impact on sustainability of fashion production and consumption in order to discuss what the main lever is to reduce the negative impact. The research methodology applied is a literature review examining academic references. Key findings suggest that fashion production and consumption have a single comparable impact on sustainability. Moreover, as the fashion production follows the demand, the consumer steers the production in a certain direction. Therefore, consumers take over responsibility and need to be informed. To reach a long-term change in the fashion industry, the consumer has to be the focus of the sustainable efforts. Most results in literature were conducted by qualitative research methods, so that further quantitative testing of the results is recommended. Furthermore, most surveys were conducted with young fashion consumers in the EU or UK which does not represent the fashion consumer in general.
The purpose of this paper is to highlight potentials and limitations of the prosumer concept in fashion retail. The paper illustrates the evolution of prosumption and in which directions the concept is being developed. The primary research is based on a literature review containing different sources of academic and non-academic references. Findings suggest that the prosumer concept is no new phenomenon. Recently, it has moved into the focus of companies that have noted that it is efficient when engaging with customers in order to strengthen their brand loyalty. An increasing number of companies offer innovative business models that underlie the concept. However, lately smart prosuming machines are changing the objectives of the concept. Even if the prosumer concept exists since many years and scholars investigate its potentials continuously, it is the fashion industry that has been researched comparatively little up to now.
This study focuses on the different roles of social media for the promotion of a sustainable lifestyle, behaviour and consumption, especially with regard to the typically non-ethical fashion industry. Research findings include eight roles of social media influencing a sustainable consumption contrary to prior research naming one to five impacts. Results show that social media educates and engages the young and ethically interested target group besides increasing supply chain transparency and brand or theme awareness. Furthermore, social media provides a platform for organisations’ relationship management and social interaction since users get empowered to share experiences which leads to a higher level of trust.
The purpose of this paper is to evaluate consisting consumption patterns caused by fast fashion with a new appearing form of consumption and retaining potentials as an alternative as well as sustainable form of fast fashion consumption. This research is set up on a theoretical background of scientific literature including governmental as well as press releases in order to evaluate the status quo of consumption and answering the research question. A new consumption pattern as well as an appearing economy of sharing can be stated including potential aspects of raising businesses and sustainable alternative forms of fast fashion. The framework of the research is limited to the textile and fashion industry in industrialized countries focusing on consumption in the twenty first century.
The purpose of this paper is to find out how musicians are able to differentiate themselves from their competitors by using their style. Casting shows and the evolution of the contestants’ style during and after the show serve as a paradigm for creating differentiation by style. The method of research was diverse but largely drawn from research papers as well as online magazines and newspapers. Within the scope of the research, it was feasible to draw on a varied range of sources to answer the research question. In the course of this research paper, it was possible to define key factors for a musician to create differentiation by style in modern times. By examining the style of casting show contestants, it was explored to which extent they transform from rather normal people to pop stars. In reducing the detailed analysis of casting shows to three shows and contestants, only a broad overview was provided. The paper is of interest to those working for casting shows in order to develop those.
Case study: Marillion
(2018)
The purpose of this paper is to highlight the use of crowdfunding,
demonstrated by a case study about the rock band Marillion. The research
methodology applied is a literature review examining academic references. On this basis, a case study by exemplary illustrating the rock band Marillion and how they invented crowdfunding has been drafted. Findings suggest that the crowdfunding concept is no new phenomenon, since the rock band Marillion has investigated the business model. Recently, the funding method is applied to the fashion industry; hence it is efficient and engaging to finance projects by that specific business model. A limitation of this paper is that the topic of crowdfunding is new to the fashion business and needs further research and tests until they are practicable to interpret. Results show that there is a high potential for using crowdfunding in fashion by reaching a long-term change in this industry.
Was ist Unternehmenskultur?
(2010)
Mitte der siebziger Jahre wurde die Unternehmenskultur als wichtige Einflussgröße für den Unternehmenserfolg erkannt. Der Begriff der Kultur wird jedoch auf vielfache Weise definiert und interpretiert, so dass in der Literatur auch kein Mangel an verschiedenen Auslegungen des Begriffes herrscht. Darüber hinaus werden in Theorie und Praxis häufig weitere Ausdrücke verwandt, die inhaltlich mit dem Begriff Unternehmenskultur übereinstimmen, wie z.B. "Firmenkultur", "Organisationskultur", oder "Corporate Culture". Dadurch ist die Diskussion über Unternehmenskultur geprägt von Missverständnissen. Im Folgenden soll daher ein Überblick gegeben werden, wie Unternehmenskultur definiert werden kann, wie sie entsteht und welche Schlussfolgerungen daraus gezogen werden können.
The purpose of this paper is to give an overview about the links between the fashion and music industry. It focuses on the idea that digitalization has broken the rules of the traditional music industry value chain. This touches both the production and the consumption side of music. This change finally also has an intense impact on the fashion industry, as the music industry has been big supplier of fashion trends itself. The absence of this supplier plus the changes within the fashion industry itself by the fast-fashion development are considered as a reason for more competition and therefore price pressure. An in-depth future research about the fashion and music system is therefore required to develop answers for the current situation. This article should be interpreted more as a personal viewpoint of the author to this topic rather than a research paper based on the usual methodological criteria.
In this chapter we introduce methods to improve mechanical designs by bionic methods. In most cases we assume that a general idea of the part or system is given by a set of data or parameters. Our task is to modify these free parameters so that a given goal or objective is optimized without violation of any of the existing restrictions.
To illustrate the power and the pitfalls of Bionic Optimization, we will show some examples spanning classes of applications and employing various strategies. These applications cover a broad range of engineering tasks. Nevertheless, there is no guarantee that our experiences and our examples will be sufficient to deal with all questions and issues in a comprehensive way. As general rule it might be stated, that for each class of problems, novices should begin with a learning phase. So, in this introductory phase, we use simple and quick examples, e.g., using small FE-models, linear load cases, short time intervals and simple material models. Here beginners within the Bionic Optimization community can learn which parameter combinations to use. In Sect. 3.3 we discuss strategies for optimization study acceleration. Making use of these parameters as starting points is one way to set the specific ranges, e.g., number of parents and kids, crossing, mutation radii and, numbers of generations. On the other hand, these trial runs will doubtless indicate that Bionic Optimization needs large numbers of individual designs, and considerable time and computing power. We recommend investing enough time preparing each task in order to avoid the frustration should large jobs fail after long calculation times.
Current fields of interest
(2016)
If we review the research done in the field of optimization, the following topics appear to be the focus of current development:
– Optimization under uncertainties, taking into account the inevitable scatter of parts, external effects and internal properties. Reliability and robustness both have to be taken into account when running optimizations, so the name Robust Design Optimization (RDO) came into use.
– Multi-Objective Optimization (MOO) handles situations in which different participants in the development process are developing in different directions. Typically we think of commercial and engineering aspects, but other constellations have to be looked at as well, such as comfort and performance or price and consumption.
– Process development of the entire design process, including optimization from early stages, might help avoid inefficient efforts. Here the management of virtual development has to be re-designed to fit into a coherent scheme.
...
There are many other fields where interesting progress is being made. We limit our discussion to the first three questions.
Application to CAE systems
(2016)
Due to the broad acceptance of CAD-systems based on 3D solids, the geometric data of all common CAE (Computer-Aided Engineering) software, at least in mechanical engineering, are based on these solids. We use solid models, where the space filled by material is defined in a simple and easily useable way. Solid models allow for the development of automated meshers that transform solid volumes into finite elements. Even after some unacceptable initial trials, users are able to generate meshes of non-trivial geometries within minutes to hours, instead of days or weeks. Once meshing had no longer been the cost limiting factor of finite element studies, numerical simulation became a tool for smaller industries as well.

In the early days of automated meshing development, there were discussions over the use of tetragonal (Fig. 4.1) or hexagonal based meshes. But, after a short period of time, it became evident, that there were and will always be many problems using automated meshers to generate hexagonal elements . So today nearly all automated 3D-meshing systems use tetragonal elements .
To prevent high buildings in endangered zones suffering from seismic attack, TMD are applied successfully. In many applications the dampers are placed along the height of the edifice to reduce the damage during the earthquake. The dimensioning of TMD is a multidimensional optimisation problem with many local maxima. To find the absolute best or a very good design, advanced optimisation strategies have to be applied. Bionic optimization proposes different methods to deal with such tasks but requires many repeated studies of the buildings and dampers design. To improve the speed of the analysis, the authors propose a reduced model of the building including the dampers. A series of consecutive generations shows a growing capacity to reduce the impact of an earthquake on the building. The proposals found help to dimension the dampers. A detailed analysis of the building under earthquake loading may yield an efficient design.
Motivation
(2016)
Since human beings started to work consciously with their environment, they have tried to improve the world they were living in. Early use of tools, increasing quality of these tools, use of new materials, fabrication of clay pots, and heat treatment of metals: all these were early steps of optimization. But even on lower levels of life than human beings or human society, we find optimization processes. The organization of a herd of buffalos to face their enemies, the coordinated strategies of these enemies to isolate some of the herd’s members, and the organization of bird swarms on their long flights to their winter quarters: all these social interactions are optimized strategies of long learning processes, most of them the result of a kind of collective intelligence acquired during long selection periods.
Dieser Beitrag entwickelt ein Managementmodell, das Unternehmen dabei unterstützt, relevante Aktionsfelder zur nachhaltigen Steuerung von Konsumenten entlang der eigenen Customer Journey zu identifizieren. Aufbauend auf dem SHIFT-Modell, als strukturelle Abbildung des nachhaltigen Käuferverhaltens, wird die Customer Journey entlang der owned, paid und earned Touchpoints aufgezogen. Mithilfe des faktisch analytischen Ansatzes, der die Integration neuer Erkenntnisse in die Forschungsstrategie unterstützt, werden Aktionsfelder identifiziert, die als grundlegende Logik Unternehmen dazu anleiten sollen, bei der Ausgestaltung der eigenen nachhaltigen Customer Journey dieses Strukturraster anzunehmen.

Nachdem Unternehmen Klarheit über das Kundenverhalten und die damit zusammenhängenden Determinanten haben, gilt es, in einem zweiten Schritt eine Strategie auszuarbeiten, die die bestmögliche Befriedigung der Kundenbedürfnisse in den Mittelpunkt des Handelns setzt. Je besser dieses den Unternehmen gelingt, umso besser lassen sich damit deren eigene Ziele verwirklichen. Dabei gilt es zunächst, einen Marketingplan zu entwickeln.
The question of why individuals adopt information technology has been present in the information systems research since the past quarter century. One of the most used models for predicting the technology usage was introduced by Fred David: The Technology Acceptance Model (TAM). It describes the influence of perceived usefulness and perceived ease of use on attitude, behavioral intention and system usage. The first two mentioned factors in turn are influenced by external variables. Although a plethora of papers exists about the TAM , an extensive analysis of the role of the external variables in the model is still missing. This paper aims to give an overview ove the most important variables. In an extensive literature review, we identified 763 relevant papers, found 552 unique single extenal variables, characterized the most important of them, and described the frequency of their appearance. Additionally, we grouped these variables into four categories (organizational characteristis, system characteristics, user personal characteristics, and other variables). Afterwards we discuss the results and show implications for theory and practice.
Der Siegeszug von Social Media im privaten Umfeld hat die Vorteile dieser Kommunikationswerkzeuge aufgezeigt. Unternehmen versuchen, diese Erfolge für sich zu nutzen und setzen Social Media für ihre Kommunikationsaktivitäten ein. In der externen Kommunikation etwa ermöglichen diese Werkzeuge einen schnellen und unkomplizierten Nachrichtenaustausch mit Kunden oder helfen Kundenexpertise in organisationale Prozesse, etwa Produktentwicklung oder Kundenbeschwerdemanagement, zu integrieren. Auch in der internen Kommunikation entstehen durch den Einsatz von Social Media neue Kanäle. Eine spezielle Gruppe von Social-Media Werkzeugen für die interne Kommunikation und Kollaboration wird als Enterprise Social Networks (ESN) bezeichnet.
Durch die Differenzierung der Produkte nach verschiedenen Kundengruppen konnte das Unternehmen seinen Marktanteil trotz des gesättigten Markts ausbauen. Neben der erstklassigen Qualtät seiner Produkte unterscheidet das Unternehmen sich nun auch noch durch seine kundengruppenspezifische Entwicklung und Vermarktung von der No-Name-Konkurrenz und den Herstellern aus Niedriglohnländern. Diese Sicherung der Marktposition wiegt die Kosten der notwendigen Flexibilisierung mehr als auf. Das Unternehmen ist durch seine neuen und innovativen Produkte besser für die Zukunft gerüstet. Es kann durch seine hervorragenden Kontakte zu seinen Kunden auf die sich ändernden Wünsche und Anforderungen seiner vielfältigen Kundschaft schnell und gezielt reagieren.
Um seinen Markterfolg zu sichern, muss ein Unternehmen schneller ans Ziel gelangen als seine Konkurrenz. Entsprechend soll ein Unternehmen neue Produkte und Dienstleistungen schnell und erfolgreich am Markt platzieren. Um dies zu ermöglichen, sind in alllen Phasen des Innovationsprozesses optimale Bedingungen zu schaffen. Der Schlüssel dazu liegt jedoch nicht nur in der gezielten Steuerung der Faktoren, die die Innovationsfähigkeit eines Unternehmens bestimmt, sondern auch im Einsatz der Fähigkeiten aller Beschäftigten. Die Nutzung des Potenzials von Frauen, älteren Mitarbeiterinnen und Mitarbeiter oder Beschäftigten unterschiedlichster Herkunft bedeutet für ein Unternehmen mehr kreative Ideen, weitere Blickwinckel und neue Herangehensweisen. Dies führt nicht nur zu verbesserten Entscheidungen und Entwicklungen, sondern insgesamt zu einer besseren Nutzung der Innovationschangsen, zu innovativeren Produkten und damit letztlich zu mehr Wachstum.
Im Beitrag "Spektrum Migration" plädieren die beiden Autor/innen für eine Sicht auf Migration, die Mobilität und Präsenz in Beziehung zueinander setzt und als einen kulturellen Prozess versteht, in welchem Eigen und Fremd, Zugehörigkeit und Ausschluss, Identität und Ethnizität verhandelt werden. Vor dem Hintergrund des Empirischen Kulturwissenschaft mit ihrem Verständnis von Kultur und Alltag und ihrer Perspektive auf gesellschaftliche Ordnungen und Prozesse stellen Klückmann und Sparacio die Bedeutung von Beziehungen und besonders Kontexten, in die Migration und ihre Folgen eingebettet sind, heraus. Sie gehen davon aus, dass es die eine Migration nicht gibt, und plädieren daher für eine Konzeption von Migration am jeweiligen zu untersuchenden Gegenstand.
The massive use of patient data for the training of artificial intelligence algorithms is common nowadays in medicine. In this scientific work, a statistical analysis of one of the most used datasets for the training of artificial intelligence models for the detection of sleep disorders is performed: sleep health heart study 2. This study focuses on determining whether the gender and age of the patients have a relevant influence to consider working with differentiated datasets based on these variables for the training of artificial intelligence models.
Digitale Selbstvermessungstechnologien wurden in den letzten Jahren zum Sinnbild rationaler und optimierter Lebensführung. Mit dem digitalen Prosumenten sind jedoch auch zahlreiche Pathologien verbunden. Der Beitrag verortet Lifelogging - digitalisierte Lebensprotokollierung - als auf Algorithmen basierende Form von Alchemie und Surrogat für echte soziale Utopien.
The paper analyses the importance of List's views on growth and integration from the perspective of modern approaches to economic growth and international economics. Furthermore, some ideas will be presented on how List's ideas could help to explain and understand current economic developments, such as the crisis of the European Union or the new form of isolationism of the United States of America.
Wie kann die Digitalisierung in der Bauzulieferbranche erfolgreich gemeistert werden? Die Fülle und Komplexität der Fragen dazu lassen sich auf zwei zentrale Kernfragen reduzieren: Was sind die richtigen Inhalte und wesentlichen Werttreiber der Digitalisierung? Und wie muss zukünftig mit der steigenden Informationsflut, der rasant wachsenden Komplexität und der abnehmenden Planbarkeit umgegangen werden?
In diesem Beitrag wird ein Framework vorgestellt, das Bauzulieferern hilft, ihr digitales Zielbild mit seinen Werttreibern systematisch aus dem Kundennutzen abzuleiten. Das Framework berücksichtigt die Besonderheiten der Bauzulieferindustrie, kann aber mit leichten Anpassungen auch auf andere Branchen angewendet werden. Aufbauend auf dem Zielbild können Unternehmen definieren, welche technischen, personellen und organisatorischen Veränderungen für dessen Umsetzung erforderlich sind. Um flexibel mit den dynamischen Veränderungen in ihrem Ökosystem und kulturellen Herausforderungen umgehen zu können, werden zudem fünf Einflussgrößen identifiziert, die Unternehmen bei der Entwicklung der dafür benötigten Evolutionskompetenz berücksichtigen müssen.
Projektmanagement
(2020)
Projektmanagement ist ein Werkzeug um singuläre Aufgaben interdisziplinär und unternehmensübergreifend strukturiert zu bearbeiten, die einmalig und extrem bedeutsam für das Unternehmen sind sowie nicht einfach in der bestehenden Linienorganisation bearbeitet werden können. Unter Projektmanagement versteht man ein Konzept für die Leitung eines komplexen Vorhabens und die Institution, die dieses Vorhaben leitet.
Personalmanagement
(2020)
Auch wenn der Wert in keiner Bilanz auftaucht: das Humankapital entscheidet über den Unternehmenserfolg. Während Kapital im Überfluss vorhanden ist, ist das Personal zunehmend der Engpassfaktor. Wurde bis in die 1980er-Jahre der Mensch als Produktionsfaktor und die Personalabteilung als seine Verwaltungsinstanz gesehen, so ist die Personalarbeit heute ein integratives Element des Managementprozesses und die Personalabteilung aktiver Teil des Managementteams (Scholz 2014c). Damit verbunden ist der begriffliche Wandel von Personalwirtschaft bzw. Personalverwaltung hin zum Personalmanagement bzw. Human Ressource Management (HRM). Die Begriffe signalisieren eine stärker strategisch ausgerichtete Auseinandersetzung mit allen Fragen, die den Einsatz von Personal und die Verknüpfung der Personal- mit der Unternehmensstrategie zum Gegenstand haben.
Wichtige Aufgaben der Personalarbeit sind Personalplanung, Personalbeschaffung, Personalentwicklung, Personaleinsatz, Personalkostenmanagement, Personalführung. Diese werden in der Regel von unterschiedlichen Stellen wahrgenommen – neben der Personalabteilung spielen dabei auch die direkte Führungskraft sowie die Unternehmensleitung eine wichtige Rolle.
