Formula One races provide a wealth of data worth investigating. Although the time-varying data has a clear structure, it is pretty challenging to analyze it for further properties. Here the focus is on a visual classification for events, drivers, as well as time periods. As a first step, the Formula One data is visually encoded based on a line plot visual metaphor reflecting the dynamic lap times, and finally, a classification of the races based on the visual outcomes gained from these line plots is presented. The visualization tool is web-based and provides several interactively linked views on the data; however, it starts with a calendar-based overview representation. To illustrate the usefulness of the approach, the provided Formula One data from several years is visually explored while the races took place in different locations. The chapter discusses algorithmic, visual, and perceptual limitations that might occur during the visual classification of time-series data such as Formula One races.
Companies compete more and more as integrated supply chains rather than as individual firms. The success of the entire supply chain determines the economic well-being of the individual company. With management attention shifting to supply chains, the role of management accounting naturally must extend to the cross-company layer as well. This book demonstrates how management accounting can make a significant contribution to supply chain success.It targets students who are already familiar with the fundamentals of accounting and now want to extend their expertise in the field of cross company (or network) management accounting. Practitioners will draw valuable insights from the text as well.
Whether diversity enhances or impedes team creativity remains an issue of scholarly debate. Explanations of this ambiguity often lie in how diversity is both operationalized and measured. Eschewing the popular approach of using differences in objective criteria to signal diversity, a deep-level approach that focuses on differences in personal values is taken in this study. Value diversity is measured in the two forms of variety and separation and their associations with team creativity are explored. The investigation is augmented by considering the mediating role of team communication in these associations. The analysis was conducted on a sample of 98 teams, using both subjective and objective measures. The findings reveal that when considering value diversity in terms of variety, there is a positive association between diversity and team creativity. However, when the separation dimension of value diversity is considered, a negative association between diversity and team creativity is identified. Complex pathways pertaining to the role of communication within these relationships are also uncovered. In moving beyond rudimentary categories and measurement of diversity, this study further elucidates the complexity of the diversity–creativity relationship. Conclusions are drawn and implications for further research and managerial practice are derived.
Kostenkalkulation im Anlagenbau: Modell zur Bewertung der Konkurrenzfähigkeit im Entwicklungsstadium
(2020)
Während Grundchemikalien größtenteils im industriellen Maßstab mittels verfahrenstechnisch optimierter Großanlagen hergestellt werden, entwickeln Forschungsinstitute biobasierte Prozesse zur Herstellung von Plattformchemikalien im Labor- und Pilotmaßstab. Im Rahmen dieser Arbeit wird ein Kostenkalkulationsmodell zur Abschätzung der Investitions- und Betriebskosten verfahrenstechnischer Anlagen vorgestellt, auf dessen Basis die ökonomische Konkurrenzfähigkeit in der Entwicklung befindlicher Verfahren ermittelt werden kann. Das Modell ist fur Anwendungen im industriellen Maßstab
geeignet.
Energieversorgungsunternehmen sehen sich gegenwärtig und mit dem Voranschreiten der Energiewende mit einer Vielzahl von Herausforderungen konfrontiert. Die zunehmende Dezentralisierung und Digitalisierung der Energiewirtschaft zwingen die EVU zusammen mit dem steigenden Wettbewerbs- und Kostendruck dazu, von den gewohnten Pfaden des Commodity-Geschäfts abzuweichen und neue Produkte und Dienstleistungen zu entwickeln sowie neue Geschäftsfelder zu erschließen. Die Kunden rücken mit ihren zunehmend individualisierten und komplexen Bedürfnissen in den Mittelpunkt des Interesses. Wollen EVU langfristig am Markt erfolgreich sein, müssen sie sich vom klassischen Energieversorger als Anbieter von einfachen Produkten hin zu innovativen, kundenzentrierten Energiedienstleistern weiterentwickeln. Ein Schlüssel hierfür stellt die Entwicklung von Energiedienstleistungen dar. Gleichzeitig tun sich viele EVU mit dieser Entwicklung jedoch aufgrund interner Hemmnisse wie fehlender personeller Kapazitäten, einer angesichts des dynamischen Marktumfeldes unflexiblen Organisation mit langen Entwicklungsdauern, geringen Budgets sowie mangelndem fachlichen und/ oder methodischen Know-How schwer. Dies zeigen die Ergebnisse der vorliegenden Studie unter Geschäftsführern und Vorständen in der Energiewirtschaft.
Airports largely outgrew their sole purpose of simply being travel hubs and by connecting millions of passengers to their destinations each year on an international scale, they have become increasingly interesting for business and related marketing opportunities. In fact, passengers are easily segmented and can be reached effectively throughout specific airport areas, making some areas more suitable for advertising than others. Emotional states, roaming time and the freedom to move vastly, influence how much information passengers are able to absorb from their direct surroundings. Finally our research shows that some areas are more suitable than others. Therefore a careful selection of airport locations for communication will be key to secure the impact and improve the effectiveness of communication measures. With these insights, advertisers can deliberately choose the areas that are most effective for displaying their ads.
Der Halo-Effekt im Fußball
(2019)
Der Halo-Effekt ist eine aus der Sozialpsychologie bekannte kognitive Verzerrung. Ein Halo-Effekt tritt dann auf, wenn ein globaler Eindruck oder eine Information über ein hervorstechendes Merkmal die Beurteilung anderer Eigenschaften prägt. Im vorliegenden Beitrag wird der Frage nachgegangen: Gibt es einen Halo-Effekt im Fußball? Überstrahlt der sportliche Erfolg bzw. Misserfolg die Wahrnehmung der Fans womöglich sogar hinsichtlich nicht-sportlicher Aspekte? Der Beitrag gibt den aktuellen Stand zur Halo-Forschung wider und präsentiert die Ergebnisse einer empirischen Untersuchung, in deren Rahmen Fans von Vereinen aus der deutschen Fußball-Bundesliga befragt werden.
Additive manufacturing (AM) is a promising manufacturing method for many industrial sectors. For this application, industrial requirements such as high production volumes and coordinated implementation must be taken into account. These tasks of the internal handling of production facilities are carried out by the Production Planning and Control (PPC) information system. A key factor in the planning and scheduling is the exact calculation of manufacturing times. For this purpose we investigate the use of Machine Learning (ML) for the prediction of manufacturing times of AM facilities.
Pharmaceutical companies are among the top investors into research and development (R&D) globally, as product innovation is still the main growth driver for the industry and because the related complexities necessitate enormous R&D investments. The market demand for new medicines to be more efficacious or to provide better safety than existing drugs and the regulatory need to prove superiority in clinical trials are reasons why drug R&D is increasingly expensive and pharmaceutical companies need to manage extraordinarily high costs per approved new compound.
