CSR und Compliance
(2018)
Viele Unternehmen befassen sich mit den Themen CSR und Compliance – in erster Linie aufgrund ihrer historischen Entwicklung – im Rahmen paralleler organisationaler Strukturen. Da CSR und Compliance nach heutigem Verständnis jedoch sowohl in der Theorie als auch in der Praxis inhaltlich zunehmend große Schnittmengen aufweisen bzw. einander wechselseitig bedingen, kann dies zu unnötigen Redundanzen und Zielkonflikten in der Umsetzung führen.
Das vorliegende Herausgeberwerk knüpft an dieser Stelle an und zeigt auf, was CSR und Compliance gemein ist, inwiefern sie einander bedingen und folglich synergetisch gemanagt werden können oder sogar sollten. Neben Wissenschaftlern sollen dazu auch explizit Praktiker zu Wort kommen, die mit der Integration von CSR- und/oder Compliancethemen betraut sind und Hinweise zu deren praktischer Umsetzung geben können.
Mit dem vorliegenden Sammelband werden daher nicht nur Wissenschaftler, sondern ausdrücklich auch Anwender angesprochen, die Denkanstöße oder konkrete Hinweise zur ganzheitlichen Integration und Umsetzung der beiden Themen aus der Lektüre mitnehmen möchten.

Further applications of the Cauchon algorithm to rank determination and bidiagonal factorization
(2018)
For a class of matrices connected with Cauchon diagrams, Cauchon matrices, and the Cauchon algorithm, a method for determining the rank, and for checking a set of consecutive row (or column) vectors for linear independence is presented. Cauchon diagrams are also linked to the elementary bidiagonal factorization of a matrix and to certain types of rank conditions associated with submatrices called descending rank conditions.
In 1970, B.A. Asner, Jr., proved that for a real quasi-stable polynomial, i.e., a polynomial whose zeros lie in the closed left half-plane of the complex plane, its finite Hurwitz matrix is totally nonnegative, i.e., all its minors are nonnegative, and that the converse statement is not true. In this work, we explain this phenomenon in detail, and provide necessary and sufficient conditions for a real polynomial to have a totally nonnegative finite Hurwitz matrix.

A constructive method for the design of nonlinear observers is discussed. To formulate conditions for the construction of the observer gains, stability results for nonlinear singularly perturbed systems are utilised. The nonlinear observer is designed directly in the given coordinates, where the error dynamics between the plant and the observer becomes singularly perturbed by a high-gain part of the observer injection, and the information of the slow manifold is exploited to construct the observer gains of the reduced-order dynamics. This is in contrast to typical high-gain observer approaches, where the observer gains are chosen such that the nonlinearities are dominated by a linear system. It will be demonstrated that the considered approach is particularly suited for self-sensing electromechanical systems. Two variants of the proposed observer design are illustrated for a nonlinear electromagnetic actuator, where the mechanical quantities, i.e. the position and the velocity, are not measured
A constructive nonlinear observer design for self-sensing of digital (ON/OFF) single coil electromagnetic actuators is studied. Self-sensing in this context means that solely the available energizing signals, i.e., coil current and driving voltage are used to estimate the position and velocity trajectories of the moving plunger. A nonlinear sliding mode observer is considered, where the stability of the reduced error dynamics is analyzed by the equivalent control method. No simplifications are made regarding magnetic saturation and eddy currents in the underlying dynamical model. The observer gains are constructed by taking into account some generic properties of the systems nonlinearities. Two possible choices of the observer gains are discussed. Furthermore, an observer-based tracking control scheme to achieve sensorless soft landing is considered and its closed-loop stability is studied. Experimental results for observer-based soft landing of a fast-switching solenoid valve under dry conditions are presented to demonstrate the usefulness of the approach.

Die Bauingenieure sind sich ihrer gesellschaftlichen Verantwortung bewusst, finden es jedoch unbefriedigend, dass ihr Anteil an der Baukultur weder ausreichend bekannt ist, noch gebührend gewürdigt wird. Der Beitrag gibt einen kurzen Überblick über diese Thematik und versucht die eigenen Defizite der Ingenieure aufzuspüren, die die Lösung des Problems erschweren. Am Beispiel von Ulrich Fintterwalder wird gezeigt, welche Haltung einer der großen Baumeister des zwanzigsten Jahrhunderts zum verantwortlichen und nachhaltigen Bauen, zur Ästhetik und Gestaltung und zur kreativen Zusammenarbeit mit Architekten eingenommen hatte.
Know when you don't know
(2018)
Deep convolutional neural networks show outstanding performance in image-based phenotype classification given that all existing phenotypes are presented during the training of the network. However, in real-world high-content screening (HCS) experiments, it is often impossible to know all phenotypes in advance. Moreover, novel phenotype discovery itself can be an HCS outcome of interest. This aspect of HCS is not yet covered by classical deep learning approaches. When presenting an image with a novel phenotype to a trained network, it fails to indicate a novelty discovery but assigns the image to a wrong phenotype. To tackle this problem and address the need for novelty detection, we use a recently developed Bayesian approach for deep neural networks called Monte Carlo (MC) dropout to define different uncertainty measures for each phenotype prediction. With real HCS data, we show that these uncertainty measures allow us to identify novel or unclear phenotypes. In addition, we also found that the MC dropout method results in a significant improvement of classification accuracy. The proposed procedure used in our HCS case study can be easily transferred to any existing network architecture and will be beneficial in terms of accuracy and novelty detection.
Sexistischer Werbung, die gegen die Menschenwürde verstößt, kann über die Auffangnorm des § 3 Abs. 1 UWG bekämpft werden. Dennoch zeigt sich die Rechtsprechung zurückhaltend und stattdessen übernimmt der Deutsche Werberat die Deutungshoheit. Die höchstrichterliche Rechtsprechung konnte sich insoweit bislang nicht fortbilden. Gerade in Zeiten des Wertewandels ist eine aktualisierte höchstrichterliche Rechtsprechung aber nicht zuletzt auch für den Rechtsfrieden unerlässlich.
The article opens with brief examples of the varied contexts in which professionals with expert knowledge of intercultural communication are commissioned
by organisations to help improve organisational and individual performance.
The development needs that are evident in these contexts entail a broader repertoire of competencies than those generally reflected in the term intercultural communication skills, and so the next section elaborates on the concept of intercultural interaction competence (ICIC), reporting on the numerous sub-competencies which go to make up the ability to perform joint and purposeful activity effectively and appropriately across cultures.
The third section reports on approaches to developing the ICIC of members of organisations, discussing desirable framework conditions for the development
intervention, its possible goals, the nature of the cognitive, affective and behavioural development outcomes which can be achieved, and the content, methods and tools available to the intercultural developer.
The article finishes with a brief consideration of the qualification profile of interculturalists engaged in this kind of work, pointing out that a multi-disciplinary background will enable interculturalists to meet a broad range of organisational and human resource development needs in the area of intercultural communication which go beyond the ‘mere’ development of communicative foreign-language skills.
Embodiments are generally related to the field of channel and source coding of data to be sent over a channel, such as a communication link or a data memory. Some specific embodiments are related to a method of encoding data for transmission over a channel, a corresponding decoding method, a coding device for performing one or both of these methods and a computer program comprising instructions to cause said coding device to perform one or both of said methods.
The introduction of multiple-level cell (MLC) and triple-level cell (TLC) technologies reduced the reliability of flash memories significantly compared with single-level cell flash. With MLC and TLC flash cells, the error probability varies for the different states. Hence, asymmetric models are required to characterize the flash channel, e.g., the binary asymmetric channel (BAC). This contribution presents a combined channel and source coding approach improving the reliability of MLC and TLC flash memories. With flash memories data compression has to be performed on block level considering short-data blocks. We present a coding scheme suitable for blocks of 1 kB of data. The objective of the data compression algorithm is to reduce the amount of user data such that the redundancy of the error correction coding can be increased in order to improve the reliability of the data storage system. Moreover, data compression can be utilized to exploit the asymmetry of the channel to reduce the error probability. With redundant data, the proposed combined coding scheme results in a significant improvement of the program/erase cycling endurance and the data retention time of flash memories.
Generalized concatenated (GC) codes with soft-input decoding were recently proposed for error correction in flash memories. This work proposes a soft-input decoder for GC codes that is based on a low-complexity bit-flipping procedure. This bit-flipping decoder uses a fixed number of test patterns and an algebraic decoder for soft-input decoding. An acceptance criterion for the final candidate codeword is proposed. Combined with error and erasure decoding of the outer Reed-Solomon codes, this bit-flipping decoder can improve the decoding performance and reduce the decoding complexity compared to the previously proposed sequential decoding. The bit-flipping decoder achieves a decoding performance similar to a maximum likelihood decoder for the inner codes.
This letter proposes two contributions to improve the performance of transmission with generalized multistream spatial modulation (SM). In particular, a modified suboptimal detection algorithm based on the Gaussian approximation method is proposed. The proposed modifications reduce the complexity of the Gaussian approximation method and improve the performance for high signal-to-noise ratios. Furthermore, this letter introduces signal constellations based on Hurwitz integers, i.e., a 4-D lattice. Simulation results demonstrate that these signal constellations are beneficial for generalized SM with two active antennas.
