The rise of digital technologies has become an important driver for change in multiple industries. Therefore, firms need to develop digital capabilities to manage the transformation process successfully. Prior research assumes that the development of a specific set of digital capabilities leads to higher digital maturity. However, a measurement framework for digital maturity does not exist in scholarly work. Therefore, this paper develops a conceptualization and measuremnent model for digital maturity.
In 2017, Philips' goal was to use innovation to improve the lives of three billion people a year by 2025. To achieve that, the company was shifting from selling medical products in a transactional manner to providing integrated healthcare solutions based on digital health technology. Based on our interviews with 23 executives at Philips, the case examines the two directions of the transformation required by this shift: externally, Philips worked on transforming how healthcare was conducted. Healthcare professionals would have to change the way they worked and reimbursement schemes needed to change to incentivize payers, providers, and patients in vastly different ways. Internally, Philips needed to redesign how its employees worked. The company componentized its business, introduced digital platforms, and co-created integrated solutions with the various stakeholders of the healthcare industry. In other words: Philips was transforming itself in order the reinvent healthcare in the digital age.
Autism spectrum disorders (ASD) affect a large number of children both in the Russian Federation and in Germany. Early diagnosis is key for these children, because the sooner parents notice such disorders in a child and the rehabilitation and treatment program starts, the higher the likelihood of his social adaptation. The difficulties in raising such a child lie in the complexity of his learning outside of children's groups and the complexity of his medical care. In this regard, the development of digital applications that facilitate medical care and education of such children at home is important and relevant. The purpose of the project is to improve the availability and quality of healthcare and social adaptation at home of children with ASD through the use of digital technologies.
Product-Service Systems (PSS) in the fashion industry : an analysis of intra-organizational factors
(2018)
The fashion industry is a vast industry that has grown tremendously over the last decades. This growth causes significant environmental impact since the production of clothes involves high input of energy, water, chemicals and generates great volumes of waste. Even though fashion firms have started to address this challenge by adopting environmental standards, it has turned out that the sole use of eco-friendly material and new manufacturing techniques is insufficient. Instead, sustainable business models are increasingly gaining attention to solve the environmental problems. Offers to rent, swap, repair or redesign clothes are among the most prominent and promising examples. For analytical purposes, these concepts can be assigned to the growing research stream of Product-Service Systems (PSS) that shift the focus from the pure sale of a product toward complementary or substitutional service offers. This decouples customer satisfaction from material consumption, prolongs the garments' lifetime and thus diminishes both material input and appertaining waste. Besides environmental sustainability, PSS imply potential economic benefits for organizations. Particularly in highly competitive industries like the fashion industry, PSS allow firms to differentiate, better compete with cost pressure and mitigate the risk of being imitated by rivels since service is more difficult to replicate. However, fashion PSS are still mainly operated in a niche market by small firms and have yet to be anchored in the mainstream fashion industry.
Anders als Digital-ICs, die hochautomatisiert entworfen werden können, ist der Entwurf analoger ICs bis heute Handarbeit. Übliche auf Optimierung basierende Automatisierungsverfahren scheitern. Die Ursachen wurden jetzt in einem Forschungsprojekt untersucht, um neue Ansätze zur Entwurfsautomatisierung analoger ICs abzuleiten.
Die Landessprache in der Lehre - welche Bedeutung kommt ihr bei der Internationalisierung zu?
(2019)
Seit der Jahrhundertwende wird erfolgreich die Intensivierung des Austauschs zwischen wissenschaftlichen Einrichtungen betrieben, auch national, aber vor allem international. Anfänglich schien klar, dass gute Indikatoren für die "Internationalisierung" genannte Entwicklung die Anteile ausländischer Wissenschaftler und Studierender sind. Konsens über sinnvolle Zielgrößen für die Indikatoren gibt es jedoch bisher nicht. Nach einiger Zeit flachte sich der anfängliche Anstieg dieser Quoten etwas ab. Mit der Folge einer weiteren Steigerung dieses Indikators ist neuerdings international der Trend zur Anglophonisierung der Lehre zu beobachten.
Additive manufacturing is a key technology which applies the ideas of Industry 4.0 in order to enable the production of personalized and highly customized products economically. Especially small and medium sized companies often lack the competence and experience to evaluate objectively and profoundly the potential of additive manufacturing technologies in small and medium sized companies. Furthermore, the method has been validated in a small medical technology company evaluating the additive manufacturing potential of an existing surgery tool.
Continuous refactoring is necessary to maintain source code quality and to cope with technical debt. Since manual refactoring is inefficient and error prone, various solutions for automated refactoring have been proposed in the past. However, empirical studies have shown that these solutions are not widely accepted by software developers and most refactorings are still performed manually. For example, developers reported that refactoring tools should support functionality for reviewing changes. They also criticized that introducing such tools would require substantial effort for configuration and integration into the current development environment.
In this paper, we present our work towards the Refactoring-Bot, an autonomous bot that integrates into the team like a human developer via the existing version control platform. The bot automatically performs refactorings to resolve code smells and presents the changes to a developer for asynchronous review via pull requests. This way, developers are not interrupted in their workflow and can review the changes at any time with familiar tools. Proposed refactorings can then be integrated into the code base via the push of a button. We elaborate on our vision, discuss design decisions, describe the current state of development, and give an outlook on planned development and research activities.
Anlass für die Ausstellung war das 150 jährige Bestehen der Hochschule Reutlingen. Ursprünglich als Webschule gegründet, später Technikum für Textilindustrie und staatliche Ingenieurschule, entwickelte sich daraus bis heute die Fachhochschule mit der Fakultät für Textil und Design. Den Schwerpunkt des historischen Teils der Ausstellung bildet die Gewebesammlung, die in der Webschule als Vorbild für die Studenten wie auch für die württembergische Textilindustrie entstand. Demgegenüber stehen aktuelle Funktionstextilien aus High-Tech-Fasern, die über die traditionelle Nutzung als Material für Bekleidung hinaus vielseitig eingesetzt werden: im Automobil- und Flugzeugbau, in der Medizintechnik, im Arbeitsschutz, an Bauwerken.
The Third International Conference on Data Analytics (DATA ANALYTICS 2014), held on August 24 - 28, 2014 - Rome, Italy, continued the inaugural event on fundamentals in supporting data analytics, special mechanisms and features of applying principles of data analytics, application oriented analytics, and target-area analytics.
Processing of terabytes to petabytes of data, or incorporating non-structural data and multistructured data sources and types require advanced analytics and data science mechanisms for both raw and partially-processed information. Despite considerable advancements on high performance, large storage, and high computation power, there are challenges in identifying, clustering, classifying, and interpreting of a large spectrum of information.
The Eleventh International Conference on Advances in Databases, Knowledge, and Data Applications (DBKDA 2019), held between June 02, 2019 to June 06, 2019 - Athens, Greece, continued a series of international events covering a large spectrum of topics related to advances in fundamentals on databases, evolution of relation between databases and other domains, data base technologies and content processing, as well as specifics in applications domains databases.
Advances in different technologies and domains related to databases triggered substantial improvements for content processing, information indexing, and data, process and knowledge mining. The push came from Web services, artificial intelligence, and agent technologies, as well as from the generalization of the XML adoption.
High-speed communications and computations, large storage capacities, and loadbalancing for distributed databases access allow new approaches for content processing with incomplete patterns, advanced ranking algorithms and advanced indexing methods.
Evolution on e-business, ehealth and telemedicine, bioinformatics, finance and marketing, geographical positioning systems put pressure on database communities to push the ‘de facto’ methods to support new requirements in terms of scalability, privacy, performance, indexing, and heterogeneity of both content and technology.

The desire to combine advanced user friendly interfaces with a product personality communicating environmental friendliness to customers poses new challenges for car interior designers, as little research has been carried out in this field to date. In this paper, the creation of three personas aimed at defining key German car users with pro environmental behaviour is presented. After collecting ethnographic data of potential drivers through literature review, information about generation and Euro car segment led to the definition of three key user groups. The resulting personas were applied to determine the most important interaction points in car interior. Finally, present design cues of eco-friendly product personality developed in the field of automotive design were explored. Our work presents three strategic directions for the design development of future in-car user interfaces named as a) foster multimodal mobility; b) emphasize the interlinkage economy - sustainable driving; and c) highlight new technological developments. The presented results are meant as an impulse for developers to fit the needs of green customers and drivers when designing user-friendly HMI components.
In an increasingly competitive environment, suppliers are now seen as an important source of innovation. Long term partnerships enable companies to access the knowledge of suppliers to optimize their business. "Procurement 4.0" is one of the concepts that come to the fore when talking about digitalization of business processes. The major aim of this research is to discuss a conceptual model of "Procurement 4.0" and its potential to rethink the management of supplier relationships, which will be one of the main future tasks of procurement. The paper is based on a factual-analytical research approach that serves to continuously specify and supplement the elements of the frame of reference: Two challenging concepts, "Procurement 4.0" and Supplier Relationship Management, are merged to contribute to the fact that purchasing is indispensable as an "interface" within a global supply chain to reap the benefits of digitization. The factors that prove to be obstacles to digital supplier relationship management along the digital supplier journey - e.g. lack of guidelines, approaches or tools and a lack of understanding of the importance of long-term relationships - are reflected within the identified technologies of digital transformation. A comprehensive analysis of the given situation within digital supplier relationship management in Germany is provided. The most important digital supplier touchpoints are discussed in order to develop a traditional supplier relationship towards a digital relationship management. Thus, this paper succeeds in illustrating how the innovative concept of a supplier journey can be implemented in practice to counteract the future, entrepreneurial challenges.
India’s growth: perspectives for Indo-European business “Skilled labour in India: bridging the gap”
(2011)
The following paper is based on a survey conducted for ESB Business School and will show how German companies perceive India’s labour market. Besides existing geographical and sectoral gaps we will reveal gaps in the required qualification profile. Thinking merely of hard qualification factors like education levels, skills etc., though, would be short-sighted. Often cited intercultural qualifications also play an important role.
What can be done? What should be done to bridge these gaps? These will be the leading questions of this chapter. We will discuss some solutions – not forgetting that the problems German companies face are complex and knowing there is no ideal way. However, we will see that some of the most urgent problems can be solved or reduced by Indo-European or Indo-German co operation models in the field of vocational training and institutions of higher education.
Since 2000, Indian special economic zones were established with the intention to attract foreign direct investment. We present a first empirical assessment with new data from 1980 to 2010 and evaluate the outcome after 10 years. In general, our empirical results confirm that special economic zones attract FDI statistical significantly. Another finding of the study is that open economies with stable inflation attract more FDI than small and closed economies.
This is the first copy of JIEBS. The papers it presents are the result of a call for papers CEBS made in 2011. We actually received far more interesting papers and research reports than expected.They all passed a double blind review and the papers naturally are the original work of the named authors. The choice we finally made was also influenced by the topic of the CEBS annual conference 2011, namely the influence of infrastructure and skilled labour on Indo-European Business. The papers analyse structure and explain many issues related to this, they raise questions and point towards areas for further research and they form the nucleus of this new and currently only scientific platform for Indo-European business studies.
Hypericin is one of the most efficient photosensitizers used in photodynamic tumor therapy (PDT). The reported treatments of this drug reach from antidepressive, antineoplastic, antitumor and antiviral activity. We show that hypericin can be optically detected down to a single molecule at ambient conditions. Hypericin can even be observed inside of a cancer cell, which implies that this drug can be directly used for advanced microscopy techniques (PALM, spt-PALM, or FLIM). Its photostability is large enough to obtain single molecule fluorescence, surface enhanced Raman spectra (SERS), fluorescence lifetime, antibunching, and blinking dynamics. Sudden spectral changes can be associated with a reorientation of the molecule on the particle surface. These properties of hypericin are very sensitive to the local environment. Comparison of DFT calculations with SERS spectra show that both the neutral and deprotonated form of hypericin can be observed on the single molecule and ensemble level.
Strong optical mode coupling between two adjacent λ/2 Fabry-Pérot microresonators consisting of three parallel silver mirrors is investigated experimentally and theoretically as a function of their detuning and coupling strength. Mode coupling can be precisely controlled by tuning the mirror spacing of one resonator with respect to the other by piezoelectric actuators. Mode splitting, anti-crossing and asymmetric modal damping are observed and theoretically discussed for the symmetric and antisymmetric supermodes of the coupled system. The spectral profile of the supermodes is obtained from the Fourier transform of the numerically calculated time evolution of the individual resonator modes, taking into account their resonance frequencies, damping and coupling constants, and is in excellent agreement with the experiments. Our microresonator design has potential applications for energy transfer between spatially separated quantum systems in micro optoelectronics and for the emerging field of polaritonic chemistry.
This paper presents an approach for the implementation of a modular and scalable power electronics device for controlling electric drives in the field of electric vehicles using wide bandgap semiconductor devices. The main idea is to achieve the required output currents or voltages by connecting adequately designed hardware modules in parallel or in series. This particular design is based on the fact that the single modules generate a continuous and specified output voltage from a given dc voltage, e.g. an intermediate circuit or battery voltage. The main benefit is, that different current or voltage requirements can be satisfied based on a single module thus decreasing development and production costs. The current paper focuses on the connection in parallel of such modules. A control architecture is illustrated and a first proof of concept is given.
