Die öffentliche Verwaltung und die in ihr lebenden und arbeitenden Menschen sehen sich häufig mit einer institutionalisierten Dilemma-Situation konfrontiert. Die Ursachen hierfür sind darin zu sehen, dass öffentliches Verwaltungshanden mit sehr wenigen Ausnahmen keinem Selbstzweck dient. Stattdessen dient es anderen Funktionssystmen und wird mit deren binären (Funktions-)Codes beobachtet und zwangsnotwendig bewertet. Die Möglichkeiten des Einzelnen, steuernd und gegebenenfalls korrigieren einzugreifen, sind in einer modernen durch extrem hohe Komplexität und (internationale) Verflechtung bestimmten Gesellschaft gering.
Die Einführung CSR- und wertebasierter Unternehmensziele und Managementmethoden wird von Führungskräften und Mitarbeitern häufig als Überforderung empfunden und löst Bedenken und teilweise Ängste aus. Diesem Phänomen kann alleine durch eine gelungene Schulung in den Theorien und Methoden entgegengetreten werden. Das hier vorgeschlagene Sechs-Schritte-Programm zur Schulung dieser Theorien und Methoden weckt das Bewusstsein für die Notwendigkeit eines Paradigmenwechsels und vermittelt den betroffenen Individuen die erforderlichen Kenntnisse und Werkzeuge, sich dieser Herausforderung zu stellen. In sechs Arbeitsschritten wird von der Phänomenologie der derzeitigen Unternehmenswelt über die theoretische Analyse der Situation bis hin zur Vorstellung geeigneter Tools und der möglichen Risiken ein Weg zur erfolgreichen Schulung gezeigt.
Different sensor types using chemical and biochemical principles are described. The former are mainly gas sensors, the latter are applied especially to liquids. Those label-free direct detection methods are compared with applications where assays take advantage of labeled receptors.
Furthermore, selected applications in the area of gas sensors are discussed, and sensors for process control, point-of-care diagnostics, environmental analytics, and food analytics are reviewed. In addition, multiplexing approaches used in microplates and microarrays are described.
On account of the huge number of sensor types and the wide range of possible applications, only the most important ones are selected here.
Military organizations have special features like following different organizational laws in times of peace and war and their specific embeddedness in society and politics. Especially the latter aspect has made the military an important object of study since the beginnings of modern sociology. In the wake of establishing specific sociological accounts, military sociology has been developed, dedicated to the different facets of the military. This research is based on different theoretical perspectives, but has hardly embraced the frameworks from economics and sociology of conventions (EC/SC) so far. The aim of the chapter is to explore and demonstrate the potentials of this approach. In a first step, the state of the art of military sociology research is outlined, and potential avenues for analyzing military forces based on EC/SC are identified. It is argued that especially the connection to organizational theory (military as organization) and civil-military relations, including leadership and professionalism, offer starting points. After introducing existing studies addressing military-related topics with reference to EC/SC, relevant concepts and approaches of convention theory that prove to be particularly enriching for military research are discussed. An outlook on possible further fields and topics of research is given to concretize how an inclusion of the perspective of EC/SC could look like.
The Internet of Things (IoT) refers to the interconnectedness of physical objects, and works by equipping the latter with sensors and actuators as a means to connect to the internet. The number of connected things has increased threefold over the past five years. Consequently, firms expect the IoT to become a source of new business models driven by technology. However, only a few early adopters have started to install and use IoT appliances on a frequent basis. So it is still unclear which factors drive technological acceptance of IoT appliances. Confronting this gap in current research, the present paper explores how IoT appliances are conceptually defined, which factors drive technological acceptance of IoT appliances, and how firms can use results in order to improve value propositions in corresponding business models. lt is discovered that IoT appliance vendors need to support a broad focus as the potential buyers expose a large variety. As conclusions from this insight, the paper illustrates some flexible marketing strategies.
Business process management and IT supported processes are an actual topic. The procedure of finding a business process system that implements your processes the best way is not easy and takes a lot of time. In this article you will find a recommendation for an open source system. Four selected open source workflow management systems are tested and analyzed. Mean criteria for the evaluation are listed in a criteria catalogue and rated by experts by their importance. Finally, the systems are evaluated by the criteria and the best evaluated system can be recommended.
In a networked world, companies depend on fast and smart decisions, especially when it comes to reacting to external change. With the wealth of data available today, smart decisions can increasingly be based on data analysis and be supported by IT systems that leverage AI. A global pandemic brings external change to an unprecedented level of unpredictability and severity of impact. Resilience therefore becomes an essential factor in most decisions when aiming at making and keeping them smart. In this chapter, we study the characteristics of resilient systems and test them with four use cases in a wide-ranging set of application areas. In all use cases, we highlight how AI can be used for data analysis to make smart decisions and contribute to the resilience of systems.
Converting users into customers : the role of user profile information and customer journey analysis
(2016)
Due to the digital transformation, the importance of web analysis and user profiling for enterprises is increasing rapidly as customers focus on digital channels to obtain information about products and brands. While there exists a lot research on these topics, only a minority of firms use them to their advantage. This study aims to tighten the link between research and business such that experimental methods can be used for the improvement of communication strategies in practice. Therefore, a systematic literature analysis is conducted, workshops are observed and documented and an empirical study is used to integrate single steps into a framework for the
practical usage of user profiling and customer journey analysis.
Ziel des Beitrages ist es, sinnlich-ästhetisch Weltzugänge am Beispiel des Designs für pädagogische Kontexte herauszuarbeiten. Gleichermaßen soll eine Reflexion darüber in Gang gesetzt werden, welche Potenziale transdisziplinär geprägte Gestaltungsprozesse für das Lernen und Lehren bereithalten. Zunächst wird daher die transdisziplinäre Natur des Designs geschichtlich hergeleitet und verschiedene Prozesse beleuchtet. Das sich anschließende Kapitel arbeitet unter dem Begriff der Gestaltung jene Merkmale und Qualitäten professionellen Designs heraus, die allen Prozessen zugrunde liegen. Abschließend wird das Konzept des Design Thinking vor dem Hintergrund erfahrungsbasierten Lernens in der Schulbildung diskutiert und mit Beispielen aus empirischen Studien untermauert.
The purpose of this paper is to give an overview about the links between fashion businesses and film from a fashion business perspective. It focuses on the idea that digitalization brought much more film use for the fashion industry and that this development has just begun and not ended. This change finally also has an intense impact on the fashion industry, as fashion companies nowadays are content producers with films, too. The resulting closer connection with viewers via social media exposes fashion companies, gives on the other hand new influence potential to the fashion system. An in-depth future research about the fashion and film 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.
Today, digitalization is firmly anchored in society and business. It is also recognized to have significant impact on the retailing sector. The in-store display of moving images has so far, however, gained little attention by researchers. The aim of this research is to provide a first estimation on the current state of moving images distribution in stationary retail stores. A store check was the basis for analysis and evaluation. In sum, 152 stores were analyzed in Stuttgart, Germany. Out of 152 observed stores, 62 stores showed 177 moving images. Detailed analyses about content, mood, color and the actors of motion pictures showed that all aspects are very well harmonized with the target group of the store. The chapter provides a basic estimation of the in-store diffusion of moving images. Thereby, avenues for further research are opened up.
This chapter provides insights in the future of fashion film with respect to augmented reality and virtual reality technologies. The question: How does augmented reality and virtual reality influence the future of fashion film? is therefore considered. It is important to analyze the influence of those technologies on fashion films to assess the potential for fashion retailers and in best case gain first-mover advantages. To answer the stated research question, a literature research was conducted to gain insights about the topic and its influence towards fashion filming. Explanation of augmented reality and virtual reality is provided as well as implications in the retail sector regarding fashion films. Moreover, company examples already using this approach have been compiled. Furthermore, an empirical research part was conducted including a survey method based on an online survey design. The questionnaire is based on what has been revealed in literature to gain in depth insides and approval. The data gained indicated that augmented reality and virtual reality influence the future of fashion film in various ways. The findings highlight how important those technologies can be in order to enhance customer experience and engagement. Regarding the research question, the conclusion can be drawn that it is highly important for fashion managers to take future developments like augmented reality and virtual reality into account to stay competitive and satisfy the requirements of modern consumers.
This chapter discusses German television as a platform for fashion content and, in that context, streaming services as possible alternatives. Three German television channels were surveilled over the period of one month, as well as the two most popular streaming services in Germany and the online media library of one German television channel over six months, regarding length, fashion connection, transmission time and success. Additionally, for three channels fashion advertisement was analyzed. Broadcasting the most contributions with fashion connection in one month, VOX was the channel being the most fashionable. Aiming to entertain, informative contributions about fashion in television build a minority. Streaming services offer more flexibility, which the user is asking for. All three television stations show fashion brand spots during prime-time. Especially ProSieben and sixx are in close cooperation with several fashion brands. Therefore, fashion advertising seems to be preferably inserted in fashion related series.
Based on new ways of watching series via streaming platforms and a change of buying behavior, advertising needs to focus on new strategies. Branded entertainment gives brands the opportunity to deeper integrate their product placements into television show plots. Through a managerial perspective this increases the advertising effectiveness. The serial ‘Sex and the City’ exemplifies successful branded entertainment and shows how series influence fashion nowadays. The placements are outstanding when it comes to storytelling around the brand or product, setting trends and creating a character connection plus a desire through identification. This chapter shows success factors and chances of placements for the fashion industry.
Hip-hop culture defines itself through four central pillars: DJing, MCing, breakdancing and graffiti, but a fifth one, fashion, may be in the coming. Hip-hop has become the most popular music genre, and the influence it has on society is undebatable. But as hip-hop artists increasingly underpin their music with visual components, like music videos, the question arises if that has an influence on the fashion industry. This chapter clarifies which factors may determine a fashion business impact and discusses differences between mainstream hip-hop artists and the ones that are active in the fashion industry as well. The focus lays on the way and amount fashion is presented in the music videos. 24 music videos were analyzed, thereof 15 popular records from the past three years and nine of artists that are already considered as fashion influential. Additionally, a fashion influence index was created to compare the degree of fashion between the music videos. Numbers of styles, recognized brands, fashion related song verses, fashion related description box mentions and articles about the fashion in the music video were noted. Findings reveal that the number of outfits shown in the video did not have a direct link to the amount of traffic it produces in fashion media. The artists that are considered influential in the fashion industry, name brands in their song lyrics more often and show brand logos more frequent in their music videos than others. Though over the observed years, for the mainstream hip-hop artists, a rise in fashion awareness can be seen through a higher number of styles, recognizable brands and fashion related verses in the lyrics.
An event film is a successful marketing and communication instrument, which can be used from companies along social media. By reaching the target group and potential customers, companies could benefit from increasing brand awareness. It is striking that there is a lack of information about how event films are used in regard to showing fashion. To establish the subject further, the purpose of this paper is to enrich the existing findings and analyze the influence event films have. In an empirical study, the performance of two events and the two related fast fashion retailers H&M and Zara on Instagram and YouTube regarding event and fashion connected films is analyzed. Identified stylistic elements of event fashion are searched and found in their online shops. Since emotions are especially well transferred through event films, there is an indication that they contribute to the shaping of fashion trends.
A case study with four German fashion retail brands was conducted in order to measure the performance of their Omnichannel services. In detail, their Click & Collect service was analyzed. Click & Collect is one of the first introduced Omnichannel services in fashion retailing. Omnichannel services integrate different sales and communication channels providing a seamless customer journey experience. Offline, online, and mobile app customer experiences should provide a seamless customer experience. Omnichannel performance of the four retailers Decathlon, Hunkemöller, Massimo Dutti and Galeria Kaufhof was measured via mystery shopping. A seamless customer journey experience is not yet a standard in German fashion retailing. The four companies differ in many process details. The biggest market potential and the recommendation for further research emerges in deficits of the offline store Omnichannel customer experience. Here, all four case companies have room to improve. Best overall results regarding the integration of offline, online and mobile shops were found with Hunkemöller, followed by Decathlon, Massimo Dutti, and Galeria Kaufhof.
The purpose of this paper is to determine the relevance of social media for luxury brand management. It employs both a multi-methodological approach: After analyzing the online performance of the three luxury brands Burberry, Louis Vuitton and Gucci, the empirical research includes a survey as well as an eye tracking test executed with Tobii Studio. The findings reveal that online and social media have given luxury fashion businesses the opportunity to establish a sustainable interaction with their customers and distinguish themselves from the competition. Still, the online business holds many challenges for luxury companies to overcome. This paper gives instructions as to how social media can be effectively incorporated into a luxury company.
Instagram fashion videos
(2020)
Instagram is one of the most used social media platforms to share photos and videos. Due to this, it can be seen as a helpful opportunity for companies to use the platform as a marketing tool in order to spread information to a wide range of potential customers. Ever since its launch, Instagram is strongly connected to fashion, which makes the platform in particular interesting for fashion brands. According to the screened literature, most brands use Instagram for marketing purposes. It is furthermore a matter of fact, that the utilization of videos plays a decisive role. Following up on this, the question about how brands use videos on Instagram for marketing purposes comes up. Due to this, this chapter aims to investigate the extent to which brands make use of videos on Instagram, what the goals of the videos are and what the most effective videos in terms of user engagement are. More specifically, this chapter includes an empirical study which examines the Instagram profiles of nine selected brands of the categories lifestyle, luxury and fashion and sportswear on the underlying research question. A subsequent evaluation and discussion of the results depicts differences and similarities within the categories and between the categories. All in all, the results of the study show that fashion brands use the possibility of films as a marketing tool on Instagram. The content and types of films thereby heavily depend on the brand category.
The purpose of this paper is to investigate how motion pictures are currently used for the product presentation of fashion articles. An explorative approach was chosen for the literature section. This study shows that the use of moving images for the presentation of fashion articles in online shops is possible in numerous different ways. In order to be able to use product presentation videos meaningfully, one should consider exactly what is the purpose of these videos. Different goals require different means. However, retailers should obtain enough information in advance to assess whether they can afford the production and post-processing of these videos.
The purpose of this paper is to investigate how motion pictures are currently used for the product presentation of fashion articles in online shops in the German, American and British markets. This study shows that the use of moving images for the presentation of fashion articles in online shops is underutilized. With the amount of data that was manageable within the scope of this chapter, no valid generalizations can be made. All described results must be understood as an indication. In order to be able to use product presentation videos meaningfully, one should consider before exactly what is the purpose of these videos. Different goals require different means. However, retailer should obtain enough information in advance to assess whether they can afford the production and post processing of these videos.
This chapter looks at the usage of image films produced by brands and their dealing with themselves. It focuses on analyzing important film parameters, the content and the way it can influence brand image. A list of 70 fashion brands from different categories was gathered through a survey and confirmed by comparing the results with relevant literature. All 70 brands were looked at to find relevant self-referencing films. The films had to be produced by the brand themselves. Videos for advertisement or promoting collections are not regarded either. In total 22 films from 17 brands were analyzed. Results show that most brands seem to have recognized videos as a powerful marketing tool in the social media age. Many brands seem to struggle with the compliance of certain parameters such as length and the use of the brand logo. In general, the content of the videos is focused around the four topics recruitment, value, history and behind the brand. As for the intent, the videos can be classified into the three categories learning, emotion and doing something. This paper not only analyzes this special film category, but also gives recommendations to improve the videos.
The connection of fashion and film seems symbiotic at first sight and they influence each other. There exist differences, including a different understanding of clothing by costume designers and fashion businesses. This article focuses on two successful movies „The Hunger Games“ and „The Great Gatsby“ in order to explore the role of film in fashion and vice versa. The findings suggest, that there are various collections in the fashion world, based on both movies. Therefore, movies indeed have an influence on the development of seasonal fashion. However, this connection is not natural, but rather artificially created by both industries. Through nowadays organized co-operation, the lines between costume designers and fashion designers get blurred. Furthermore, today fashion doesn’t trickle down to an audience naturally, but promoted using the film and its broad reach.
Fashion show films
(2020)
Due to technological developments, fashion show films provide fashion brands the opportunity to communicate their brand concepts, to attract attention and to gain more brand awareness by publishing them in the Internet. The purpose of this research paper is to investigate how fashion brands communicate their brand concept and personality through fashion show films. For this purpose, ten fashion show films of brands from the categories luxury, premium, high-street and active wear are investigated. The results indicate that the investigated brands use different ways to attract attention and to communicate their brand concept and personality. The design of the setting, the presentation of the collection as well as the visualization of the brand concept through the brand name, logo, colors or symbols and camera work play an important role to create an effective and exciting fashion show film in order to communicate the brand concept and to promote their brand image. Mostly luxury and premium brands use fashion show films for branding. For high-street and active wear brands the analysis indicates less importance of fashion show films. The limitations of this research are related to the fact that the restricted number of ten fashion show films is analyzed. This gives an overview but cannot provide a comprehensive breakdown of this topic.
YouTube fashion videos
(2020)
YouTube is the most widely adopted and successful video sharing platform. It works as a marketing instrument and money-making tool for companies while reaching the target group. After considering the significant literature based on YouTube, it is striking that there is lack of information about YouTube’s benefits as a video marketing instrument for fashion brands. To establish this subject further, the purpose of this study is to enrich the existing findings on social video marketing on YouTube in the apparel industry. The findings indicate the importance of YouTube as a social network for fashion marketers. The second part conducts an empirical study, which makes the YouTube channel performance of nine fashion brands the subject of discussion. Thereby, three brands per lifestyle, sports and luxury sector are analyzed through comparative aspects. Accordingly, the differences and similarities within and between the sectors are analyzed and evaluated.
A configuration-management-database driven approach for fabric-process specification and automation
(2014)
In this paper we describe an approach that integrates a Configuration- Management-Database into fabric-process specification and automation in order to consider different conditions regarding to cloud-services. By implementing our approach, the complexity of fabric processes gets reduced. We developed a prototype by using formal prototyping principles as research methods and integrated the Configuration-Management-Database Command into the Workflow- Management-System Activiti. We used this prototype to evaluate our approach. We implemented three different fabric-processes and show that by using our approach the complexity of these three fabric-processes gets reduced.
Dieser Beitrag beschreibt das Markenmanagement von Profifußballvereinen durch den Einsatz von Social Media. Um sich ein stückweit vom nichtplanbaren sportlichen Erfolg unabhängig zu machen, sollten sich Fußballvereine als Marke positionieren. Dazu steht ihnen allerdings traditionellerweise ein geringes Marketingbudget zur Verfügung. Social Media bietet Fußballvereinen die Möglichkeit, relativ kostengünstig und effektiv die eigene Marke aufzubauen und zu pflegen. Der Beitrag erläutert diesbezüglich die Notwendigkeit eines systematischen Markenmanagements, geht auf die Besonderheiten der Vermarktung eines Profifußballvereins ein und zeigt anhand von Beispielen, wie Social Media zum Markenaufbau respektive zur Markenpflege genutzt werden kann.

Vor mehr als einem Jahrzehnt stellten die Autoren dieses Beitrags die folgende Denkaufgabe:
“Imagine the business of sports without fans. No spectators at sports matches, no buyers of merchandising, no potential customers for sponsoring companies, no recipients for the sports media. Such a scenario would be unthinkable.“ (Bühler & Nufer, 2010, S. 63)
Während der Corona-Pandemie 2020/21 wurde das Undenkbare dann aber doch Realität, als Zuschauer auf der ganzen Welt keine Sportveranstaltungen mehr besuchen durften. Das größte Sportevent der Welt, die Olympischen Spiele in Tokio 2020, mussten verschoben werden und fanden ein Jahr später unter nicht wirklich besseren Bedingungen vor so gut wie leeren Rängen statt. Das Gleiche galt für die UEFA EURO 2020, die ebenfalls um ein Jahr verschoben werden musste, dann aber zumindest (bis auf wenige Ausnahmen wie beispielsweise das Finale in Wembley) mit reduzierter Zuschauerzulassung stattfinden konnte. Hintergrund der Überlegungen sowohl des Internationalen Olympischen Komitees wie auch der Europäischen Fußballunion war damals die Befürchtung, dass ihre jeweiligen Premiumprodukte ohne Fans in den Stadien leiden würden. Natürlich gab es immer noch Millionen von Menschen, die Live-Streams von Sportveranstaltungen verfolgten oder in diesen schwierigen Corona-Zeiten allerhand Merchandise ihrer Lieblingsmannschaften kauften. Doch die Pandemie bestätigte einmal mehr die Grundregel im Sportbusiness: Der Wirtschaftsmarkt Sport im Allgemeinen und professionelle Sportorganisationen im Besonderen brauchen Fans, die bereit sind, ihre Zeit, ihre Emotionen und ihr Geld für ihren Lieblingssport und ihre Lieblingsmannschaften zu investieren. Zuschauer sind die primären – und wohl wichtigsten – Kunden eines Sportunternehmens. Daher ist es für jede professionelle Sportorganisation unerlässlich, eine nachhaltige Beziehung zu ihren Fans aufzubauen und aufrechtzuerhalten und sie auf jede mögliche Weise einzubeziehen. Vor diesem Hintergrund wird die Bedeutung des Fan-Engagements deutlich.
Die digitale Transformation ist die heute vorherrschende geschäftliche Transformation, die einen starken Einfluss darauf hat, wie digitale Dienstleistungen und Produkte dienstleistungsdominant gestaltet werden. Eine beliebte zugrundeliegende Theorie der Wertschöpfung und des wirtschaftlichen Austauschs, die als dienstleistungsdominante Logik (S-D) bekannt ist, kann mit vielen erfolgreichen digitalen Geschäftsmodellen verbunden werden. Allerdings ist die S-D-Logik an sich abstrakt. Unternehmen können sie nicht ohne Weiteres als Instrument für die Innovation und Gestaltung von Geschäftsmodellen nutzen. Um dies zu ändern, wird eine umfassende Ideenfindungsmethode auf der Grundlage der S-D-Logik vorgeschlagen, die als service-dominantes Design (SDD) bezeichnet wird. SDD zielt darauf ab, Unternehmen beim Übergang zu einer service- und wertorientierten Perspektive zu unterstützen. Die Methode bietet eine vereinfachte Möglichkeit, den Ideenfindungsprozess auf der Grundlage von vier Modellkomponenten zu strukturieren. Jede Komponente besteht aus praktischen Implikationen, Hilfsfragen und Visualisierungstechniken, die aus einer Literaturrecherche, einer Anwendungsfallbewertung der digitalen Mobilität und einer Fokusgruppendiskussion abgeleitet wurden. SDD ist ein erster Schritt zu einem Toolset, das etablierte Unternehmen bei der Service- und Werteorientierung im Rahmen ihrer digitalen Transformation unterstützen kann.
Silicon neurons represent different levels of biological details and accuracies as a trade-off between complexity and power consumption. With respect to this trade-off and high similarity to neuron behaviour models, relaxation-type oscillator circuits often yield a good compromise to emulate neurons. In this chapter, two exemplified relaxation-type silicon neurons are presented that emulate neural behaviour with energy consumption under the scale of nJ/spike. The first proposed fully CMOS relaxation SiN is based on mathematical Izhikevich model and can mimic a broad range of physiologically observable spike patterns. The results of kinds of biologically plausible output patterns and coupling process of two SiNs are presented in 0.35 μm CMOS technology. The second type is a novel ultra-low-frequency hybrid CMOS-memristive SiN based on relaxation oscillators and analog memristive devices. The hybrid SiN directly emulates neuron behaviour in the range of physiological spiking frequencies (less than 100 Hz). The relaxation oscillator is implemented and fabricated in 0.13 μm CMOS technology. An autonomous neuronal synchronization process is demonstrated with two relaxation oscillators coupled by an analog memristive device in the measurement to emulate the synchronous behaviour between spiking neurons.
Stress is becoming an important topic in modern life. The influence of stress results in a higher rate of health disorders such as burnout, heart problems, obesity, asthma, diabetes, depressions and many others. Furthermore individual’s behavior and capabilities could be directly affected leading to altered cognition, inappropriate decision making and problem solving skills. In a dynamic and unpredictable environment, such as automotive, this can result in a higher risk for accidents. Different papers faced the estimation as well as prediction of drivers’ stress level during driving. Another important question is not only the stress level of the driver himself, but also the influence on and of a group of other drivers in the near area. This paper proposes a system, which determines a group of drivers in a near area as clusters and it derives the individual stress level. This information will be analyzed to generate a stress map, which represents a graphical view about road section with a higher stress influence. Aggregated data can be used to generate navigation routes with a lower stress influence to decrease stress influenced driving as well as improve road safety.
The blockchain technology represents a decentralised database that stores information securely in immutable data blocks. Regarding supply chain management, these characteristics offer potentials in increasing supply chain transparency, visibility, automation, and efficiency. In this context, first token-based mapping approaches exist to transfer certain manufacturing processes to the blockchain, such as the creation or assembly of parts as well as their transfer of ownership. This paper proposes a prototypical blockchain application that adopts an authority concept and a concept of smart non-fungible tokens. The application enables the mapping of complex products in dynamic supply chains that require the auditability of changeable assembling processes on the blockchain. Finally, the paper demonstrates the practical feasibility of the proposed application based on a prototypical implementation created on the Ethereum blockchain.
Mit dem International Mystery Matching (IMM) wurde im International Office der Hochschule Reutlingen (HSRT) eine digital gestützte Möglichkeit geschaffen, neue Mitstudierende oder Kolleginnen und Kollegen in der Pause kennenzulernen. Der vorliegende Beitrag stellt die Einführung und Umsetzung dieses innovativen Angebots zur Vernetzung internationaler und deutscher Studierender sowie von Mitarbeitenden im Hochschulkontext vor. Dabei wird zunächst die Herausforderung der sozialen Integration der internationalen Studierenden erläutert, um anschließend genauer auf das Vorgehen bei der Einführung sowie der Umsetzung des IMM an der HSRT als Lösungsmöglichkeit einzugehen. Ein weiterer Schwerpunkt liegt auf dem Feedback der Studierenden sowie den bisherigen praktischen Erfahrungen mit dem Angebot. Die Ergebnisse einer eigenen Befragung sowie der DAAD-Mobilitätsstudie (BintHo) bestätigen den Bedarf der Zielgruppe an einer besseren Integration im Zusammenhang mit dem Studium an der HSRT.
Die KI trägt schon heute wesentlich mit zu unserem Wohlstand bei und wird dies in Zukunft immer mehr tun. Aber sie treibt wie alle technologischen Erfindungen seit der Dampfmaschine das Wirtschaftswachstum weiter an. Weil die Grenzen des Wachstums auf dem Planeten Erde aber längst überschritten sind, müssen wir hier gegensteuern. Dieses Steuern kann und soll nicht durch ein Verbot der Forschung erfolgen. Denn der Wissensdrang von uns Menschen ist gut und wichtig. Verbote sind wichtig zum Beispiel beim Einsatz von autonomen Kampfrobotern, aber nicht bei einzelnen Produkten und Dienstleistungen.
Das Mittel der Wahl zur Steuerung der Wirtschaft ist das Wirtschaftssystem. Die Wirtschaft hat in erster Linie dem Gemeinwohl zu dienen und nicht dem Kapital oder dem Geld. Darin sind sich die großen Wirtschaftspioniere Adam Smith, John Maynard Keynes und Karl Marx einig. Gefragt ist daher eine Reform von Wirtschafts- und Finanzsystem.
Unternehmen, die restriktiv keinerlei Adaptionen innerhalb der Strukturen vornehmen, können angesichts der verschärften Wettbewerbssituation im tagtäglichen Business nicht bestehen. Warum Agilität ein geeignetes Tool für die Umsetzung einer innovativen Anpassung beschreibt und in zukunftsorientierten Unternehmen als Katalysator agiert, soll in diesem Artikel näher erläutert werden.
Nachhaltige Managementmodelle sind auf Erfüllung der Triple Bottom Line ausgerichtet: Unternehmen adressieren Energie- und Co2-Effizienz (ökologisch), Arbeitsschutz oder Arbeitslosenquoten (sozial) sowie mögliche Wachstumspotenziale, die durch Nachhaltigkeit zu erreichen sind, um das eigene Überleben des Unternehmens am Markt zu sichern (ökonomisch). Daneben stehen die 17 Sustainable Development Goals (SDGs), die bis 2030 als Leitlinie nachhaltigen Wirtschaftens weltweit gelten und in nationale Gesetzgebung überführt wurden. Dieser Beitrag entwickelt ein Managementmodell, das Unternehmen dabei unterstützt, relevante SDGs zu identifizieren und Handlungsempfehlungen abzuleiten. Aufbauend auf einer nachhaltigen Supply Chain ordnet das Modell die SDGs den Dimensionen der Triple Bottom Line zu, um kurz eine Checkliste möglicher zu berücksichtigender Nachhaltigkeitsmaßnahmen im Kontext des Behaviour Change Modells zu erarbeiten. Zurückgreifend auf die Empfehlungen der Vereinten Nationen wird ein nachhaltiger Managementansatz eingeführt, der Unternehmen dazu befähigt, Governance, Transparenz und Engagement in ihrer Supply Chain zu implementieren.
Accurate monitoring of a patient's heart rate is a key element in the medical observation and health monitoring. In particular, its importance extends to the identification of sleep-related disorders. Various methods have been established that involve sensor-based recording of physiological signals followed by automated examination and analysis. This study attempts to evaluate the efficacy of a non-invasive HR monitoring framework based on an accelerometer sensor specifically during sleep. To achieve this goal, the motion induced by thoracic movements during cardiac contractions is captured by a device installed under the mattress. Signal filtering techniques and heart rate estimation using the symlets6 wavelet are part of the implemented computational framework described in this article. Subsequent analysis indicates the potential applicability of this system in the prognostic domain, with an average error margin of approximately 3 beats per minute. The results obtained represent a promising advancement in non-invasive heart rate monitoring during sleep, with potential implications for improved diagnosis and management of cardiovascular and sleep-related disorders.
Reality mining refers to an application of data mining, using sensor data to drive behavioral patterns in the real world. However, research in this field started a decade ago when technology was far behind today's state of the art. This paper discusses which requirements are now posed to applications in the context of reality mining. A survey has shown which sensors are available in state-of-the-art smartphones and usable to gather data for reality mining. As another contribution of this paper, a reality mining application architecture is proposed to facilitate the implementation of such applications. A proof of concept verifies the assumptions made on reality mining and the presented architecture.
The acquisition of data for reality mining applications is a critical factor, since many mobile devices, e.g. smartphones, must be capable of capturing the required data. Otherwise, only a small target group would be able to use the reality mining application. In the course of a survey, we have identified smartphone features which might be relevant for various reality mining applications. The survey classifies these features and shows how the support of each feature has changed over the years by analyzing 143 smartphones released between 2004 and 2015. All analyzed devices can be ranked by their number of provided features. Furthermore, this paper deals with quality issues which have occurred during carrying out the survey.
Broad acceptance of finite-element-based analysis of structural problems and the increased availability of CAD-systems for structural tasks, which help to generate meshes of non-trivial geometries, have been setting a standard for the evaluation of designs in mechanical engineering in the last few decades. The development of automated or semi-automated optimizers, integrated into the Computer-Aided Engineering (CAE)-packages or working as outer loop machines, requiring the solver to do the analysis of the specific designs, has been accepted by most advanced users of the simulation community as well. The availability and inexpensive processing power of computers is increasing without any limitations foreseen in the coming years. There is little doubt that virtual product development will continue using the tools that have proved to be so successful and so easy to handle.
Nicht-kommerzielle Gast-Gastgeber-Beziehungen sind im Tourismus kein neues Phänomen, ermöglichen sie ursprünglich überhaupt Reisen. Die Verbreitung neuer Gastfreundschaftsnetzwerke im digitalen Zeitalter veränderte jedoch etwas: zu Grunde liegende Werte wie Freundschaft und Authentizität, Selbst-Erfahrung, Netzwerkpflege und ökonomisches Kalkül scheinen besondere Reise-Erlebnisse zu konstituieren und die etablierten Touristik-Unternehmen vor ganz neue Herausforderungen zu stellen... Dahinter stehen grundlegende Fragen guter Lebensführung, wie diese bereits in der Nikomachischen Ethik des Aristoteles thematisiert wurden.
Virtual prototyping of integrated mixed-signal smart sensor systems requires high-performance co-simulation of analog frontend circuitry with complex digital controller hardware and embedded real-time software. We use SystemC/TLM 2.0 in conjunction with a cycle-count accurate temporal decoupling approach (TD) to simulate digital components and firmware code execution at high speed while preserving clock-cycle accuracy and, thus, real-time behavior at time quantum boundaries. Optimal time quanta ensuring real-time capability can be calculated and set automatically during simulation if the simulation engine has access to exact timing information about upcoming inter-process communication events. These methods fail in the case of non-deterministic, asynchronous events, resulting in potentially invalid simulation results. In this paper, we propose an extension to the case of asynchronous events generated by blackbox sources from which a priori event timing information is not available, such as coupled analog simulators or hardware in the loop. Additional event processing latency or rollback effort caused by temporal decoupling is minimized by calculating optimal time quanta dynamically in a SystemC model using a linear prediction scheme. We analyze the theoretical performance of the presented predictive temporal decoupling approach (PTD) by deriving a cost model that expresses the expected simulation effort in terms of key parameters such as time quantum size and CPU time per simulation cycle. For an exemplary smart-sensor system model, we show that quasi-periodic events that trigger activities in TD processes are handled accurately after the predictor has settled.
