For a long time, a large number of top managers in listed companies have regarded communication with their shareholders as a necessary evil and now, in times of activist investors, are faced not only with the great challenges of opening up to shareholders and revealing their own corporate strategy, but also at the same time have to withstand the massive external pressure from activist investors, who are rarely majority shareholders. To achieve this, it is essential that a complete rethink-ing of the communication strategy of those responsible for the company takes place.
Stagnation Flow and Heat Transfer From a Finite Disk Situated Perpendicular to a Uniform Stream
(2019)
Als erste deutsche Hochschule wurde die FH Münster im Sommer 2017 systemreakkreditiert.
Grundlage der Akkreditierungsentscheidung war ein Konzept,
das die Hochschule im Herbst 2014 im Kontext der Experimentierklausel“
des Akkreditierungsrats entwickelt hatte. Mittlerweile stößt dieses Konzept auf reges Interesse bei anderen systemakkreditierten Hochschulen, bietet doch das geänderte Akkreditierungsrecht seit Januar 2018 explizit die Möglichkeit, in Abstimmung mit dem Akkreditierungsrat und der jeweils zuständigen Wissenschaftsbehörde „alternative Akkreditierungsverfahren“ zu gestalten Vor diesem Hintergrund erläutert der Aufsatz den Kontext der Experimentierklausel, das Reakkreditierungsverfahren der FH Münster und die Neugestaltung des Akkreditierungsrechts.
Vor allem aber werden die Gründe, die zur Entwicklung des neuen Ansatzes führten, dargestellt, bevor dann das kumulative Akkreditierungskonzept der FH Münster skizziert wird. Die Ausarbeitung schließt mit ersten Hinweisen darauf, welche Argumente bei der Entscheidung zwischen einem alternativen – hier: kumulativen – und einem konventionellen Reakkreditierungsverfahren abzuwägen sind.
The quality management system of FH Münster, a German university of applied sciences with 15.000 students, was established ten years ago. The main goal was to systematically foster reflection on quality issues in all faculties. In 2016, the concept was transferred to the level of institutional reaccreditation: A procedure called „cumulative accreditation“ was implemented, including e.g. a public symposium.
On both levels, the author experienced that joint reflection on quality issues may encourage academics to change habits and improve study programmes. However, sometimes desirable changes will not happen. Instead of asking for sanctions and incentives, the article suggests another approach: the creation of learning opportunities for university members.

One way or another – The relationship between trust and transparency in buyer-supplier relationships
(2019)
Based on a variety of environmental, technological, and product-orientated changes, there has been a shift towards increased collaboration between buyers and suppliers. This paper examines the mutual influence of trust and transparency at different developmental stages of these collaborative relations. In particular, the research investigates the existence of a direct correlation between trust and transparency, as well as indirect dependencies to each other through environmental factors. An extensive literature review combined with an exploratory-qualitative World Café method was conducted in an attempt to fill the research gap regarding the correlation of trust and transparency in buyer-supplier relationships.
Particularly in times of disruptive changes, companies need an early warning system for risks in their supply chains to gain relevant information in a timely manner. Furthermore, they require suitable action plans and strategies to help react when a risk occurs. Based on an in-depth case study at an automotive parts supplier producing electronic systems and lighting components, this paper develops a holistic supply chain risk management framework. After investigating the specific supply chain risks to support critical parts management, standardised processes and procedures are developed to improve the preventive supply chain risk strategy cycle, as well as the reactive critical parts management cycle.
Buying firms lack transparency about the supplier relationships in their networks. The applica-tion of dedicated tools such as Supply Network Mapping (SNM) can help to visualize and analyze these relationships. However, the impact of such tools on the purchasing performance has not been explored yet. Moreover, companies with different competitive strategies might have different motivations to use these tools. Therefore, this paper tests the impact of supplier relationship information and SNM on the purchasing performance on a large sample of 624 purchasers. A multi-group analysis in structural equation modeling estimates the impact of a cost leadership versus a differentiation strategy on cost saving and innovation performance. We show that information quality and SNM indeed improve the purchasing performance. Moreover, cost leaders use SNM if they know their supplier relationships with sub-suppliers, while innovation leaders use it if they know their supplier relationships with other customers. Hence, our results prove the usefulness of the SNM tool and give recommendations for its use depending on a company’s competitive strategy.
Most companies have realized the high importance of becoming the preferred customers of their suppliers to obtain preferential resource allocation. However, they cannot evaluate their own customer attractiveness properly. In order to make the assessment of the own customer status possible, this paper analyzes the impact of several information sources on the preferred customer status knowledge, supplier satisfaction knowledge and knowledge of alternative supplier relationships with other customers. Testing these hypotheses on a sample of 624 pur-chasers, we show that people provide more relevant information on the company’s strategic positioning than media. In particular, the suppliers, competitors and other actors are very im-portant information sources. Following our findings, purchasers should adopt their activities in order to better anticipate their suppliers’ intention and the customer treatment that they can expect from their suppliers.
A major requirement for Credit Scoring models is of course to provide a risk prediction that is as accurate as possible. In addition, regulators demand these models to be transparent and auditable. Thus, in Credit Scoring very simple Predictive Models such as Logistic Regression or Decision Trees are still widely used and the superior predictive power of modern Machine Learning algorithms cannot be fully leveraged. A lot of potential is therefore missed, leading to higher reserves or more credit defaults. This talk presents an overview of techniques that are able to make “black box” machine learning models transparent and demonstrate how they can be applied in Credit Scoring. We use the DALEX set of tools to compare a traditional scoring approach with state of the art Machine Learning models and asses both approaches in terms of interpretability and predictive power. Results show that a comparable degree of interpretability can be achieved while machine learning techniques keep their ability to improve predictive power.
Identification of noise pollution in neonatal intensive care units based on work process analyses

Der Anschluss privater Schmutzwasserleitungen an Regenwasserkanäle und die Verknüpfung der Schmutzwasserkanalisation mit der Regenwasserkanalisation führen zu nennenswerten Stoffeinträgen in die Gewässer. Belastbare Zahlen zu den Größenordnungen von Fehleinleitungen und der daraus resultierenden Ge-wässerbelastung fehlen bislang. Im Rahmen des Forschungsvorhabens DETEK-T der FH Münster und der Dr. Pecher AG wurden Detektionsmöglichkeiten unter-sucht und Strategien zur Beseitigung der Fehlanschlüsse erarbeitet. Aus den bisherigen Ergebnissen wird der Frachteintrag für den Parameter CSB in NRW abgeschätzt.
Instandhaltungen und Wartungsdienstleistungen sind Tätigkeiten, die korrekt, effizient und sicher durchgeführt werden müssen, damit die betroffenen Maschinen im Anschluss fehlerfrei genutzt werden können. Reparatur-/Bedienungsanleitungen sowie ergänzende Schulungen sind erforderlich, damit gerade im B2B-Kontext Kunden und Partner diese Leistungen sicher erbringen können. Die Nutzung entsprechender Anleitungen ist fehleranfällig, Schulungs-inhalte können zudem ohne praktischen Einsatz schnell in Vergessenheit geraten. Daher wird für den Kontext der Lehre und Transfer der Augmented Reality Technologie ein Prototyp entwickelt, der hierzu ein Lösungsszenario praktisch erlebbar gestaltet und sowohl auf Smartphones und Tablets aber auch auf einer AR-Brille (Microsoft Hololens) erprobt werden kann. Studierende und Unternehmen können so den Mehrwert abschätzen und auf eigene Bereiche übertragen.

Strategically Aligning Additive Manufacturing Supply Chains for Sustainability and Effectiveness
(2019)
This paper builds on a previously developed framework that integrated additive manufacturing, life-cycle analysis, and value creation (Feldmann & Kirsch, 2019) by exploring conditions related to the life-cycle approach that would require alignment among suppliers, additive manufacturing firms, and customers. This extension creates a bridge to aid implementation of taking a sustainability approach to additive manufacturing. In order to develop this extension, we distinguish between direct/indirect customers and internal/external customers and then create a matrix of incentives and cognitive frames that we believe will help companies interested in large-scale AM improve both the speed and the effectiveness of AM adoption. We provide an organizing framework that managers can use to create a supply chain that is aligned around closed-loop principles that will help speed adoption and move closer to sustainable goals that exist for AM technologies. These include reduced raw material use, reduced scrap and material overage, and reduced rework, and lower transportation costs. The goal is to attain often-conflicting goals of lower long-term costs and decreased environmental footprint. Using our extension, we believe we can provide a useful framework to help managers implementing advanced manufacturing technologies to achieve lower costs and greater environmental sustainability by creating a common supply chain framework around customized, on-demand products.
Digitalization and sustainable development are goals of the global community, but can they also be achieved simultaneously? This article investigates the impacts of additive manufacturing (AM) on sustainable production and consumption. The use of AM technology as a means of digitalizing manufacturing processes is assessed through a qualitative life cycle analysis.
The model developed for this purpose provides a structure for an analysis of the general ecological effects of AM. The systematics of the life cycle model also supports a company-specific assessment.
AM can have a positive impact on achieving sustainable development with regards to ecological effects, particularly by reducing the consumption of resources in production and distribution. However, there are also negative ecological impacts of this technology, such as rebound effects and high energy consumption, which vary depending on the application and the printing process. It appears necessary for regulatory policy to intervene to maximize the opportunities for the positive effects of this technology. However, it is important to reduce the risks that contradict the objectives of the 12th Sustainable Development Goal of the UN: sustainability of consumption and production.
Die Digitalisierung betrifft sämtliche Bereiche und damit auch das Projektmanagement. Die erforderlichen Kompetenzen eines Projektmanagers oder einer Projektmanagerin sind folglich ebenso Änderungen unterworfen. In der Systematik der Individual Competence Baseline der International Project Management Association wurden die dokumentierten erforderlichen Kompetenzelemente im Rahmen einer Studie in Bezug auf ihre Veränderung durch Digitalisierung untersucht. Während der Bereich der persönlichen und sozialen Kompetenz-elemente klaren Veränderungen unterworfen ist, werden die Auswirkungen zum Teil ambivalent bewertet. Bei den technischen Kompetenzelementen stellt sich heraus, dass digitale Tools eine steigende Bedeutung gewinnen, auf die Projektmanager vorbereitet sein müssen. Auswirkungen auf die Elemente des Bereichs Kontext-Kompetenzen beziehen sich vorrangig auf konkrete gestaltbare Strukturen im Gegensatz zu abstrakteren Größen wie Macht und Interessen. Durch die Ergebnisse der Studie sind Anforderungen an die Qualifi-zierung von aktuellen und zukünftigen Projektmanagern abzuleiten.

Learn anything, anytime, anywhere is the mantra for learning in the digital age. Digital learning opportunities are increasingly challenging traditional classroom learning – but what does this mean for the conceptual design and design-in-use of campus spaces as learning locations? Does space really not matter in learning? During a two-day design thinking workshop an interdisciplinary group of 17 students produced ideas for new learning spaces and mapped out their spatial learning journeys through campus offerings and daily routines. The article describes the workshop concept and resulting insights gleaned from interviews, customer journeys, and prototyping. It offers ideas and examples for creating inviting learning spaces and cultures that focus on co-presence both with and without digital tools.

The water balance of urban areas differs considerably from the landscape water balance. Increased surface runoff, reduced groundwater recharge and evaporation change the hydrological regime, the morphology and ecology of water bodies close to the cities, the groundwater in the urban area and the urban climate. Today's urban drainage systems are designed to prevent, reduce, drain, seep away, evaporate or discharge precipitation into nearby surface waters with considerable delays. In doing so, it follows the principles of the German Water Resources Act (WHG) and the objectives of the relevant technical regulations DWA-A 102 to keep changes in the natural water balance by settlement activities as low as ecologically, technically and economically acceptable. A reference for the "natural" water balance has to be defined as a planning objective in order to quantify the hydrological changes in settlements. As a suitable reference, we propose to use the water balance of the landscape of the associated ecoregion with today's cultural land use without urban developments. This approach is more suitable to define local conditions than the water balance of the enclosed catchment. The presented calculation approach to define reference values of the water balance, uses soil and geological properties, precipitation and climate data and can be implemented and applied uniformly throughout Germany. The water balances in this study are simulated with the water balance model RoGeR. In this study, the developed approach is applied for five locations in Germany.
Bewertung von Substrataufschlussverfahren zur Steigerung des Gasertrages auf Basis von Experimenten

Lifestyle diseases are linked with hyper-reactivity of inflammatory and immune cells. These cells generate free radicals in the patients, which results in oxidative stress. Recent studies have brought attention to the role of oxidative stress, defined as an imbalance between reactive oxygen species (ROS) and antioxidants. Our research was focused on studying the effects of a community-based lifestyle intervention program on oxidative stress paraments in the plasma of a rural German community. In our study, we examined 105 participants in the intervention group and 70 participants in the control group. The intervention group received 10 weeks of intensive intervention in the form of seminars and workshops. The plasma levels were analyzed at baseline and after 10 weeks of intervention. This is a first-of-itskind study which elucidates the impact of an intensive lifestyle intervention program on the oxidative stress markers in German rural participants. The primary focus of our study was to motivate and encourage participants to switch over toward a healthier lifestyle by improving their knowledge and making them more aware of the principles of healthy living. This may be a useful community program approach, modifiable for different communities by health-services planners in the coming future.
Im Rahmen einer nachhaltigen Stadtentwicklung wird der Vegetation die
Funktion der Beschattung und Verdunstung zugesprochen. Der Stadthydrologie fehlte hierfür bislang ein geeignetes Simulationsmodell. Der entwickelte Modellbaustein SWMM-UrbanEVA erlaubt die standortgerechte Simulation der Verdunstung von Vegetation im urbanen Raum. Für Freiflächen erfolgt die Prozessmodellierung des Energie- und Wasserhaushaltes des Systems Boden-Pflanze-Atmosphäre. Mit meteorologischen und vegetationskundlichen Kenndaten wird eine raum-zeitlich differenzierte Berechnung ermöglicht.
