Traditional human resource management (HRM) research can hardly relate to today's developments in the world of work. Organizational boundaries are blurred because of the complexity due to globalization, digitalization, and demographic changes. In practice, new ways of organizing work can be found that depend on the specifics of the work situation. In this paper, we build on the economics of convention (EC) to elaborate on the current challenges HRM scholarship is confronted with and provide a theoretical lens that goes beyond the tension between market and bureaucracy principles in actual employment settings. We apply EC's situationalist methodology to examples of the challenging coordination of flexibility in the workplace. We explain two hybrid forms of coordination - compromises and local arrangements - and highlight the dynamics of employment practices in organizations related to these forms. Thereby, we show that different modes of coordination in employment are applied in a fluctuating manner that depends on the specific situations. In doing so, we further seek to remind HRM scholars of the fruitfulness of the pragmatist perspective in analyzing work practices, as well as extending its conceptual toolkit for future analysis.}, language = {en} } @article{HerzogFerencz2019, author = {Herzog, Bodo and Ferencz, Marlene}, title = {Disziplinierung ohne politische Diskriminierung: warum es Marktkr{\"a}fte in der W{\"a}hrungsunion bedarf!}, series = {Ifo-Schnelldienst / Ifo-Institut f{\"u}r Wirtschaftsforschung}, volume = {72}, journal = {Ifo-Schnelldienst / Ifo-Institut f{\"u}r Wirtschaftsforschung}, number = {1}, publisher = {Institut f{\"u}r Wirtschaftsforschung}, address = {M{\"u}nchen}, issn = {0018-974X}, url = {http://nbn-resolving.de/urn:nbn:de:bsz:rt2-opus4-24348}, pages = {20 -- 22}, year = {2019}, abstract = {Die Reform der W{\"a}hrungsunion sollte folgende zwei Aspekte verkn{\"u}pfen: einerseits die {\"U}bernahme einer st{\"a}rkeren politischen Stabilit{\"a}tsverantwortung und andererseits die St{\"a}rkung der Marktkr{\"a}fte.

However, since precise identification of oxide layers by visual inspection is difficult and time consuming due to inhomogeneous colour distribution, a reliable and efficient method for estimating their thickness is needed. In this study, hyperspectral imaging in the visible wavelength range (425-725 nm) is proposed as an in-line inspection method for analysing oxide layers in real-time during processing of copper components such as printed circuit boards in the automotive industry. For implementation in the production line a partial least square regression (PLSR) model was developed with a calibration set of n = 12 with about 13,000 spectra per sample to determine the oxide layer thickness on top of the technical copper surfaces. The model shows a good prediction performance in the range of 0-30 nm compared to Auger electron spectroscopy depth profiles as a reference method. The root mean square error (RMSE) is 1.75 nm for calibration and 2.70 nm for full cross validation. Applied to an external dataset of four new samples with about 13,000 spectra per sample the model provides an RMSE of 1.84 nm for prediction and demonstrates the robustness of the model during real-time processing. The results of this study prove the ability and usefulness of the proposed method to estimate the thickness of oxide layers on technical copper.

Cells permeating narrow channels exhibited blebbing and had smooth leading edge profiles, suggesting an ECM-induced transition from mesenchymal invasion to amoeboid invasion. Live cell labeling revealed a mechanosensing period in which the cell attempts mesenchymal-based migration, reorganizes its cytoskeleton, and proceeds using an amoeboid phenotype.

Cryogels were additionally supplemented with different types of proteins, namely collagen (Coll), platelet rich plasma (PRP), immune cells-conditioned medium (CM), and RGD peptides (RGD). The different protein components did not affect scaffolds' porosity or water-uptake capacity, but altered pore size and stiffness. Stiffness was highest in scaffolds with PRP (82.3 kPa), followed by Coll (55.3 kPa), CM (45.6 kPa), and RGD (32.8 kPa). Scaffolds with PRP, CM, and Coll had the largest pore diameters (~60 µm). Ad MSCs were osteogenically differentiated on these scafffolds for 14 days. Cell attachment and survival rates were comparable for all four scaffolds. Runx2 and osteocalcin levels only increased in Ad-MSCs on Coll, PRP and CM cryogels. Osterix levels increased slightly in Ad-MSCs differentiated on Coll and PRP cryogels. With differentiation alkaline phosphatase activity decreased under all four conditions. In summary, besides Coll cryogel our PRP cryogel constitutes as an especially suitable carrier for bone tissue engineering.

However, using containers leads to a new paradigm for service development and operation: Self service environments enable software developers to deploy and operate container based systems on their own - you build it, you run it. Following this approach, more and more operational aspects are transferred towards the responsibility of software developers.

Gene transcription profiles of models based on dASCs and MAs were analyzed with regard to native adipose tissue. Compared to MAs, dASCs showed an immature differentiation state.

In this case study, empirical approaches are developed to understand how market instruments could be introduced into environmental services and how to apply co-benefit approach in a green economy paradigm for Indonesia. We investigate the feasibility of introducing market instruments in Indonesia by appliying local co-benefit initiatives adapted from German experiences in integrating market instruments into MSW management practices. Currently co-benefit activities are undertaken in the Sukunan village (Yogjakarta) to promote waste composting using market incentives in the framework of community-based solid waste management (CBSWM). This scheme aims at reducing MSW generation at its source and mobilizing people to be involved in waste separation (organic and non-organic) at household levels. As a result, about 200,000 t of CO2 emissions could be successfully reduced annually. By integrating market instruments into waste management practices, the result of our studies sugggests that Indonesia could make positive changes to its environmental policy and regulation of MSW at local levels.

Seen as the contribution to the research field of sustainabitliy reporting the paper points out that a continuous qualitative reporting process with a focus on education for SD is an adequate and efficient approach to sustainability reporting for universities and an effective way to reach a broad public. We show that there are several efficient methodss of communication ranging from the traditional sustainability report to publications which address the public and to more innovative methods using the web 2.0. We show and argue that for universities, alternative ways of sustainability communication may be more effective to achieve the sustainability mission. The concept which we present gives the universities a broader impact on society and helps them to support sustainable development in an efficient way.}, language = {en} } @article{MayerGallGutmannTextoretal.2019, author = {Mayer-Gall, Thomas and Gutmann, Jochen and Textor, Torsten and Hugo, Achim and Todt, Katharina and Schmidt, Frank and Weimann, Johannes and K{\"o}nig, Claudia}, title = {Cleanable bag filter : comparisons of different testing methods of ageing of filter materials}, series = {Technical textiles : innovation, technology, application}, volume = {62}, journal = {Technical textiles : innovation, technology, application}, number = {4}, publisher = {IBP, Internat.

A qualitative comparison is conducted through a categorization of the programs' content and a score system evaluating the programs' concepts. Findings: Key findings were that several factors ensure successful fashion business education: Industry connections, international networks, project-based work, personalized career services and innovative approaches in teaching that include all steps along the fashion value chain. Research limitations/implications: The research was primarily limited due to the limited number of schools assessed. As a result of the restricted time frame, those schools that were presented could only be analyzed regarding a few aspects. Future research should focus on a more in-depth analysis and further-reaching comparisons, e.g. comparisons with teaching concepts outside the fashion business area or with requirements by fashion companies.}, language = {en} } @book{DietrichBug2019, author = {Dietrich, Laura Franziska and Bug, Peter}, title = {Exploring the role of podcasts in the fashion industry}, publisher = {Reutlingen University}, address = {Reutlingen}, doi = {10.34645/opus-2381}, url = {http://nbn-resolving.de/urn:nbn:de:bsz:rt2-opus4-23815}, pages = {223}, year = {2019}, abstract = {After definition and the history of podcasts, in this book the role of podcasts in the communication strategy is mapped out.

Because of large inter-individual variances in the middle ear, especially in wideband tympanometry (WBT), specificity and quantitative evaluation are greatly restricted. A new model-based approach could transform today's predominantly qualitative hearing diganostics into a quantitative and tailored, patient-specific diagnosis, by evaluating WBT measurements with the aid of a middle-ear model. For this particular investigation, a finite element model of a human ear was used. It consisted of an acoustic ear canal and a tympanic cavity model, a middle-ear with detailed nonlinear models of the tympanic membrane and annular ligament, and a simplified inner-ear model. This model has made it possible to identify pathologies from measurements, by analyzing the parameters through senstivity studies and parameter clustering. Uncertainties due to the lack of knowledge, subjectivity in numerical implementation and model simplification are taken into account by the application of fuzzy arithmetic. The most confident parameter set can be determined by applying an inverse fuzzy method on the measurement data. The principle and the benefits of this model-based approach are illustrated by the example of a two-mass oscillator, and also by the simulation of the energy absorbance of an ear with malleus fixation, where the parameter changes that are introduced can be determined quantitatively through the system identification.}, language = {en} } @incollection{Schwarz2019, author = {Schwarz, Sybille}, title = {Die W{\"o}rz´sche Heuristik}, series = {Von Br{\"u}cken, Menschen und Systemen : Festschrift f{\"u}r Michael W{\"o}rz}, booktitle = {Von Br{\"u}cken, Menschen und Systemen : Festschrift f{\"u}r Michael W{\"o}rz}, editor = {Banke, Bernd}, publisher = {Hochschule Reutlingen}, address = {Reutlingen}, isbn = {978-3-9821179-1-1}, doi = {10.34645/opus-2346}, url = {http://nbn-resolving.de/urn:nbn:de:bsz:rt2-opus4-23463}, pages = {97 -- 103}, year = {2019}, language = {de} } @incollection{Eisenbarth2019, author = {Eisenbarth, Peter}, title = {Das Verhalten im Straßenverkehr als Beispiel fehlender Akzeptanz von Normen}, series = {Von Br{\"u}cken, Menschen und Systemen : Festschrift f{\"u}r Michael W{\"o}rz}, booktitle = {Von Br{\"u}cken, Menschen und Systemen : Festschrift f{\"u}r Michael W{\"o}rz}, editor = {Banke, Bernd}, publisher = {Hochschule Reutlingen}, address = {Reutlingen}, isbn = {978-3-9821179-1-1}, url = {http://nbn-resolving.de/urn:nbn:de:bsz:rt2-opus4-23448}, pages = {75 -- 86}, year = {2019}, language = {de} } @incollection{Berendes2019, author = {Berendes, Jochen}, title = {Blinde Flecken.

Its power management unit operates over a large temperature range using a zero temperature coefficient bias source. On-chip temperature sensing is accomplished with low-voltage, low-power CMOS circuitry, and time-domain signal processing. Two readout commands have been defined to study supply noise sensitivity: 1) standard readout, where just a single set of data is transferred to the reader and 2) serial readout, where several sets of data are sent one after the other to the reader. With the standard readout command, the sensor suffers from interference from the RFID command packet and outputs interference as well, while the sensor outputs no interference with the serial readout command. Measurements show that sensor resolution with serial readout is improved by a factor of approximately 16 compared to standard readout. The chip was fabricated in a standard 0.35-μm CMOS technology and chip-on-board mounted to a tuned RFID transponder coil on an aluminum core FR4 PCB substrate. Real time wireless temperature sensing has been demonstrated with a commercial HF RFID reader.

High parallelism and resource-efficient append-only data placement on secondary storage is enabled. One major issue in indexing tuple versions on modern hardware technologies is the high write amplification for tree-indexes. Partitioned B-Trees (PBT) [5] is based on the structure of the ubiquitous B+ Tree [8]. They achieve a near optimal write amplification and beneficial sequential writes on secondary storage. Yet they have not been implemented in a MVCC enabled DBMS to date. In this paper we present the implementation of PBTs in PostgreSQL extended with SIAS.

Design teaching encompasses a variety of skills that can help schools shift their focus to foster children's natural ability to "ask why" in their search for learning how to think and create. This article presents the results of an interdisciplinary workshop involving university students aiming to develop new educational approaches to foster children's creativity through design to be implemented in the elementary school curriculum of the German federal state Baden-W{\"u}rttemberg. To support the workshop participants in providing a holistic concept within a compressed time period, a sustainability framework was included to further articulate their brief. The teams who were composed of chemists, computer scientists, designers, and engineers, followed the Design Thinking process to develop their proposals. A kick-off meeting presenting results of an international qualitative survey with elementary school teachers, as well as expert input during the workshop addressing the relevant topics, provided teams with key information to define their design directions. Concepts designed by each team exhibited a comprehensive solution resulting in both the abstract "education idea" and physical embodiments of the tools. Their outputs included products, interior concepts to be implemented in classrooms, exercises as well as games to support the newly developed educational models. The benefits and limitations of these concepts along with key observations of participants' interdisciplinary collaboration are presented and discussed herein. Future work will investigate the Design knowledge of German elementary school teachers more in depth and will involve testing the new concepts in German elementary school environments.}, language = {en} } @inproceedings{ThomasKoeseSchmittetal.2018, author = {Thomas, Bernd and K{\"o}se, Ekrem and Schmitt, Peter and Bark, Cyrus and Rieder, Karl and Hamer, Burkhard}, title = {Stromoptimierte, flexible und residuallastangepasste KWK in der elektrochemischen Beschichtungsindustrie GalvanoFlex_BW : Zwischenbericht anl{\"a}sslich des Statuskolloquiums Umweltforschung Baden-W{\"u}rttemberg 2018, 19./20.

However, newly added modules might be unstable, resource-intensive, or untrustworthy. Thus, satisfying non-functional requirements such as reliability, efficiency, and security while ensuring rapid release cycles is a challenging task. In this paper, we discuss how to tackle these issues by employing container virtualization to isolate modules from each other according to a specification of isolation constraints. We satisfy non-functional requirements for cloud services by automatically transforming the modules comprised into a container-based system. To deal with the increased overhead that is caused by isolating modules from each other, we calculate the minimum set of containers required to satisfy the isolation constraints specified.

The programme will be structured in such a way as to maintain or improve the level of innovation at the learning factories of each partner. The partners agreed to use Learning Factory focus areas along with DIME learning modules to stimulate international collaboration. Furthermore, they identified several research areas within the framework of the DIME program to encourage horizontal and vertical collaboration. Vertical collaboration connects faculty expertise across the Learning Factory network to advance knowledge in one of the focus areas, while Horizontal collaboration connects knowledge and expertise across multiple focus areas. Together they offer a platform for students to develop disciplinary and cross-disciplinary applied research skills necessary for addressing the complex challenges faced by industry. Hence, the university partners have the opportunity to develop the learning factory capabilities in alignment with the smart manufacturing concept. The learning factory is thus an important pillar in this venture. While postgraduate students/researchers in the DIME program are the enablers to ensure the success of entire projects, the learning factory provides a learning environment which is entirely conducive to fostering these successful collaborations. Ultimately, the partners are focussed on utilising smart technologies in line with the digitalization of the production process.}, language = {en} } @inproceedings{PetrovKochHardocketal.2019, author = {Petrov, Ilia and Koch, Andreas and Hardock, Sergej and Vin{\c{c}}on, Tobias and Riegger, Christian}, title = {Native storage techniques for data management}, series = {2019 IEEE 35th International Conference on Data Engineering : 8 - 11 April 2019, Macau, SAR, PR China : proceedings}, booktitle = {2019 IEEE 35th International Conference on Data Engineering : 8 - 11 April 2019, Macau, SAR, PR China : proceedings}, editor = {Jensen, Christian}, publisher = {IEEE}, address = {Piscataway, NJ}, isbn = {978-1-5386-7474-1}, doi = {10.1109/ICDE.2019.00236}, pages = {2048 -- 2051}, year = {2019}, abstract = {In the present tutorial we perform a cross-cut analysis of database storage management from the perspective of modern storage technologies.
