Automatic content creation system for augmented reality maintenance applications for legacy machines
(2024)
Augmented reality (AR) applications have great potential to assist maintenance workers in their operations. However, creating AR solutions is time-consuming and laborious, which limits its widespread adoption in the industry. It therefore often happens that even with the latest generation machines, instead of an AR solution, the user only receives an electronic manual for the equipment operation and maintenance. This is commonplace with legacy machines. For this reason, solutions are required that simplify the creation of such AR solutions. This paper presents an approach using an electronic manual as a basis to create fast and cost-effective AR solutions for maintenance. As part of the approach, an application was developed to automatically identify and subdivide the chapters of electronic manuals via the bookmarks in the table of contents. The contents are then automatically uploaded to a central server and indexed with a suitable marker to make the data retrievable. The prepared content can then be accessed for creating context-related AR instructions via the marker. The application is characterized by the fact that no developers or experts are required to prepare the information. In addition to complying with common design criteria, the clear presentation of the contents and the intuitive use of the system offer added value for the performance of maintenance tasks. Together, these two elements form a novel way to retrofit legacy machines with AR maintenance instructions. The practical validation of the system took place in a factory environment. For this purpose, the content was created for a filter change on a CNC milling machine. The results show that inexperienced users can extract appropriate content with the software application. Furthermore, it is shown that maintenance workers, can access the content with an AR application developed for the Microsoft HoloLens 2 and complete simple tasks provided in the manufacturer's electronic manual.
Das Thema des Direktvertriebs (Direct-to-Customer oder kurz D-to-C) in der Automobilindustrie ist en vogue, denn nach Valtech (2023, S. 2) ist die Umstellung der Vertriebsmodelle in dieser Branche unumgänglich. Die Covid-19-Pandemie hat zudem noch als Katalysator für den D-to-C fungiert und die digitale Transformation sowie die Akzeptanz virtueller Verkaufsprozesse beschleunigt.
Tech hubs (THs) and cognate structures are nowadays ubiquitous in the innovation ecosystem of Sub-Saharan African (SSA) countries. However, the concept of THs is fuzzy due to the lack of a clear and universally accepted definition. This ambiguity is further compounded by the diverse range of organizations that self-identify as hubs, or are categorized as such by others. As a result, research on THs in SSA remained limited. Against the backdrop of established research on the interconnectedness of technology, innovation and entrepreneurship in different organizational forms, this paper is meant to provide fresh insights into the study of THs in SSA. To advance future research, first, it reveals what is special about THs in SSA and how they are related to existing concepts. I particularly argue that they contour a fourth-wave model of incubation. Second, four main categories are unfolded to delineate THs in SSA which is the cornerstone for future research.
This paper explores the application of People Analytics in
recruiting professors for universities of applied sciences. Using data-driven personas, the research project aims to identify and communicate the different paths and connections leading candidates to a professorship. The authors introduce the concept of personas, describe the underlying data source and derive an example for the current project.
The dawn of the 21st Century has witnessed a tremendous increase in trade pacts among nations, resulting in renewed hopes for sustainable enterprise development in emerging economies worldwide. Ghana and other sub-Saharan African (SSA) countries have signed onto several North-South and South-South free trade agreements with the hope of strengthening their presence in the international trade arena, and to promote economic growth in SSA. For over two decades, however, very little has changed, and many have dashed their high hopes as enterprises continue to struggle in SSA. Not even the African Continental Free Trade Agreement (AfCFTA) could renew the hopes of sceptics. Several studies opined that enterprises in SSA could improve their domestic and international competitiveness by establishing mutually beneficial partnerships with their counterparts from the Global North and South. This study delved into the issues that affect North-South and South-South business collaborations and recommends key success factors that could help promote mutually beneficial cross-border business partnerships. The research includes both literature and empirical information on the key success factors of business partnerships between African enterprises as well as between African enterprises and firms from the Global North. We approached the study qualitatively using a phenomenological research design. Research participants included important stakeholders in Africa and Europe's international trade and sustainable enterprise development ecosystem. The study identified several challenges with the current business collaborations and recommended new ways of making such partnerships more beneficial.
Digitalisierung in Corporate Mergers & Acquisitions (M&A)-Prozessen birgt ein erhebliches Potenzial zur Effizienz- und Effektivitätssteigerung, erfährt jedoch bislang in der betrieblichen Praxis nur eine geringe Aufmerksamkeit. Dieser Beitrag schlägt angesichts dessen ein Reifegradmodell vor, womit sich der Ist-Stand der digitalen Reife eines Unternehmens bei Corporate M&A ermitteln und darauf aufbauend Optimierungspotenziale identifizieren lassen. Grundlage der Modellerstellung sind einerseits eine Analyse der vorhandenen Reifegradmodelle und andererseits Interviews mit M&A-Experten unterschiedlicher Unternehmen.
The blockchain technology represents a decentralised database that stores information securely in immutable data blocks. Regarding supply chain management, these characteristics offer potentials in increasing supply chain transparency, visibility, automation, and efficiency. In this context, first token-based mapping approaches exist to transfer certain manufacturing processes to the blockchain, such as the creation or assembly of parts as well as their transfer of ownership. This paper proposes a prototypical blockchain application that adopts an authority concept and a concept of smart non-fungible tokens. The application enables the mapping of complex products in dynamic supply chains that require the auditability of changeable assembling processes on the blockchain. Finally, the paper demonstrates the practical feasibility of the proposed application based on a prototypical implementation created on the Ethereum blockchain.
Purpose
Job advertisements are important means of communicating role expectations for management accountants to the labor market. They provide information about which roles are sought and expected. However, which roles are communicated in job advertisements is unknown so far.
Design/methodology/approach
With a text-mining approach on a large sample of 889 job ads, the authors extract information on roles, type of firm and hierarchical position of the management accountant sought.
Findings
The results indicate an apparent mix of different role types with a strong focus on a classic watchdog role. However, the business partner role is more often sought for leadership positions or in family businesses and small- and medium-sized enterprises (SME).
Research limitations/implications
The main limitation is the lack of an agreed-upon measurement instrument for roles in job offers. The study results imply that corporate practice is not as theory-driven as is postulated and communicated in the management accounting community. This indicates the existence of a research-practice gap and tensions between different actors in the management accounting field.
Practical implications
The results challenge the current role discussion of professional organizations for management accountants as business partners.
Originality/value
The authors contribute the first study, which explicitly analyzes the communication of roles in job offers for management accountants. It indicates a discrepancy between scholarly discussion on roles and management accountants' work from an employer's perspective.
This study examines the phenomenon of Virtual Influencer (VI) marketing and its impact on customer purchase behavior. The aim is to understand the scope and impact of VI marketing. The study compares VI marketing to traditional Human Influencer (HI) marketing and identifies the unique benefits and challenges associated with VIs. A survey was conducted to gain insight into consumer attitudes and behaviors toward VIs. Key findings reveal varying levels of trust and acceptance of VIs among consumers. While some participants expressed openness to buying products promoted by VIs, others had reservations about their authenticity. The study also explores the potential role of VIs in the metaverse, highlighting business opportunities and challenges in this evolving digital landscape. Overall, this research sheds light on the growing influence of VIs and the need for further research in the field of marketing.
This study examines the underexplored areas of customer success management, focusing on the impact of leadership and companywide collaboration, and the role of customer success in overall firm performance. A qualitative research approach was utilized, which involved reviewing relevant literature and conducting an interview with the Vice President of Customer Success Management in B2B at a case company. Findings revealed that both leadership and pervasive collaboration greatly enhance the customer journey experience. Given that 75% of Annual Recurring Revenue is derived from existing customers, the substantial role of customer success in propelling business growth is affirmed. The study also demonstrated the importance of proactive customer engagement, assimilating customer feedback into products and services, and nurturing personal relationships with customers for fostering innovation. It further stressed the need for service provision and decision-making at various levels, as well as the implementation of a range of communication channels, to ensure customer success.
In countries such as Germany, where municipalities have planning sovereignty, problems of urban sprawl often arise. As the dynamics of land development have not substantially subsided over the last years, the national government decided to test the instrument of ‘Tradable Planning Permits’ (TPP) in a nationwide field experiment with 87 municipalities involved. The field experiment was able to implement the key features of a TPP system in a laboratory setting with approximated real socioeconomic and planning conditions. In a TPP system allocated planning permits must be used by municipalities for developing land. The permits can be traded between local jurisdictions, so that they have flexibility in deciding how to comply with the regulation. In order to evaluate the performance of such a system, specific field data about future building areas and their impact on community budgets for the period 2014–2028 were collected. The field experiment contains several sessions with representatives of the municipalities and with students. The participants were confronted with two (municipalities) and four (students) schemes. The results show that a trading system can curb down land development in an effective and also efficient manner. However, depending on the regulatory framework, the trading schemes show different price developments and distributional effects. The unexperienced representatives of the local authorities can easily handle with the permits in the administration and in the established market. A trading scheme sets very high incentives to save open space and to direct development activities to areas within existing planning boundaries. It is therefore a promising instrument for Germany and also other regions or countries with an established land-use planning system.
This paper presents a description model for smart, connected devices used in a manufacturing context. Similar to the wide spread adoption of smart products for personal and private usage, recent developments lead to a plethora of devices offering a variety of features and capabilities. Manufacturing companies undergoing digital transformation demand guidance with respect to the systematic introduction of smart, connected devices. The introduction of smart connected devices constitutes a strategic decision cost due to the high future committed cost after introduction and maintaining a smart device fleet by a vendor. This paper aims to support the introduction efforts by classifying the devices and thus helping companies identify their specific requirements for smart, connected devices before initiating widespread procurement. By mapping the features of these devices based on various attributes, allows the clustering of smart, connected devices including a requirement list for their implementation on the shopfloor. Four individual commercially available smart connected devices were analyzed using the description model.
Parallel grippers offer multiple applications thanks to their flexibility. Their application field ranges from aerospace and automotive to medicine and communication technologies. However, the application of grippers has the problem of exhibition wear and errors during the execution of their operation. This affects the performance of the gripper. In this context, the remaining useful life (RUL) defines the remaining lifespan until failure for an asset at a particular time of operation occurs. The exact lifespan of an asset is uncertain, thus the RUL model and estimation must be derived from available sources of information. This paper presents a method for the estimation of the RUL for a two-jaw parallel gripper. After the introduction to the topic, an overview of existing literature and RUL methods are presented. Subsequently, the method for estimating the RUL of grippers is explained. Finally, the results are summarized and discussed before the outlook and further challenges are presented.
Towards a sustainable future, looking beyond the system boundaries of a single manufacturing company is necessary to promote meaningful collaborations in terms of circular economy principles. In this context digital data processing technologies to connect the potential collaborators are seen as enablers to make use of proven collaborative circular business models (CCBMs). Since most of such data processing technologies rely on features to describe the entities involved, it is essential to provide guidance for identifying and selecting the relevant and most appropriate ones. Defining critical success factors (CSFs) is considered a suitable instrument to describe the decisive factors. A systematic literature review (SLR), followed by a qualitative synthesis is investigating two scientific fields of work, namely (1) the general relevant features of CCBMs and, (2) methodologies for determining CSFs. This results in the development of a conceptual framework which provides guidance for digital applications that perform further digital processing based on the relevant CSFs relating to the specific CCBM.
Die vorliegende Studie beschäftigt sich mit der Verbreitung des Customer-Success-Managements im deutschsprachigen Mittelstand und der Frage, wie eine erfolgreiche Implementierung dort durchgeführt werden kann. Die Ergebnisse zeigen, dass, vorgelagert zum eigentlichen Customer-Success-Management-Prozess, interne sowie externe Voraussetzungen im deutschsprachigen Mittelstand geschaffen werden müssen, um eine nachhaltige Implementierung gewährleisten zu können. Dazu zählt die Transformation vom reinen Produktfokus hin zu einer kunden- und servicezentrierten Unternehmensstrategie. Voraussetzung dafür ist die Erhöhung des Digitalisierungsgrads der Produkte und internen Prozesse sowie ein aktives Change-Management.
Twitter and citations
(2023)
Social media, especially Twitter, plays an increasingly important role among researchers in showcasing and promoting their research. Does Twitter affect academic citations? Making use of Twitter activity about columns published on VoxEU, a renowned online platform for economists, we develop an instrumental variable strategy to show that Twitter activity about a research paper has a causal effect on the number of citations that this paper will receive. We find that the existence of at least one tweet, as opposed to none, increases citations by 16-25%. Doubling overall Twitter engagement boosts citations by up to 16%.
The 17 SDGs, as agreed upon by the international community, are designed to be implemented across all levels of human activity. Alongside the level of international politics, this also includes the local levels, national politics, wider society, and the economic sphere. Many channels are called on to further implementation, including the transfer of technology to developing and emerging countries. As the patent holders, this must include the active participation of companies. While the literature examines the important role of technology transfer in North-South business-to-business (B2B) partnerships, studies on the technology transfer between European and African companies are scarce. Therefore, in this study we use original data from 26 interviews conducted with managers engaged in sales partnerships between German manufacturers and their distributors in African markets to examine the existence and forms of technology transfer. We find that training and marketing excellence are the predominant forms of technology transfer and based on that suggest a refinement of established frameworks on B2B technology transfer.
Der Einsatz von spielerischen Elementen gewinnt im B-to-B immer mehr an Bedeutung. Die vorliegende Studie untersucht den Einsatz von Gamification-Elementen im B-to-B-Marketing und -Vertrieb, speziell in der deutschen Baubranche. Dabei zeigt sich, dass Gamification in Richtung der Mitarbeitenden häufiger genutzt wird als in Richtung der Kundschaft. Doch auch mit Blick auf nachrückende Kunden-Generationen wächst das Potenzial von Gamification zur Lead-Generierung und zur Unterstützung der Omni-Channel-Strategie.
In den letzten Jahren hat der Trend zur Digitalisierung und Konnektivität die Kundenerwartungen an den B2B-Kundenservice verändert. Vorliegender Artikel arbeitet mit zwei klaren Studienzielen und untersucht zum einen die Rolle von IoT (Internet of Things) und Cybersicherheit als Erfolgsfaktoren für den Business-to-Business (B2B) Kundenservice und zum anderen wie eine sichere Integration zu einem Wettbewerbsvorteil auf dem deutschen Markt beitragen kann. Durch einen qualitativen Ansatz mithilfe von 20 Befragungen wurde untersucht, dass IoT und Cybersicherheit als Erfolgsfaktoren für den deutschen B2B-Kundenservice angesehen werden können. Als Ergebnis liefert diese Studie fünf Kernaussagen (Hypothesen) aus qualitativen Interviews. Neben der Diskussion allgemeiner Erfolgsfaktoren und deren Einfluss, wurde die Rolle von IoT bei der Optimierung des B2B Kundendienstes diskutiert. Zudem werden potenzielle Sicherheitsrisken in Zusammenhang mit den Dienstleistungsmodellen, notwendige Anforderungen an Cybersicherheit sowie Datenerfassung erörtert. Abschließend wurde ein Modell entwickelt, das interne und externe Aspekte aufzeigt, die dazu beitragen, dass IoT und Cybersicherheit als Erfolgsfaktoren in der Aktivitätskette des Kunden in der Pre-Sales‑, Sales- und After-Sales-Phase erlebt werden.
Dieser praxis-nahe und industrie-übergreifende Artikel liefert somit Einblicke basierend auf qualitativen Erkenntnissen für weitere Forschung in der Theorie und befähigt Organisationen das Thema ganzeinheitlich zu betrachten.
Die Coronapandemie hat Deutschland seit dem Frühjahr 2020 fest im Griff. Eine zentrale Maßnahme zur Verlangsamung der Ausbreitung des Coronavirus war von Beginn an die Schließung von Schulen. In einer ersten Studie wurden die Lernzeitverluste durch die Corona-bedingten Schulschließungen im Frühjahr 2020 quantifiziert (Wößmann, Freundl, Lergetporer, Grewenig, Werner & Zierow, 2020). Es zeigte sich, dass sich die Lernzeit der Schülerinnen und Schüler durch die Schulschließungen halbiert hatte und die Verluste bei leistungsschwächeren Schülerinnen und Schülern besonders groß waren. Im Frühjahr 2020 wurde die Verringerung der Lernzeit von den Schulen nicht kompensiert: Nur ein kleiner Teil der Schülerinnen und Schüler hatte in dieser Phase regelmäßigen Distanzunterricht und täglichen Kontakt mit Lehrkräften. Während der Sommer- und Herbstmonate seit der Phase der ersten Schulschließungen hatten Schulverwaltung, Schulen und Lehrkräfte Zeit, sich auf Distanzunterricht und digitale Lehrmethoden umzustellen, um Lernausfällen während etwaiger erneuter Schulschließungen entgegenzuwirken. Inwiefern dies dazu geführt hat, dass die Schülerinnen und Schüler während der Schulschließungen Anfang 2021 tatsächlich mehr Zeit mit Lernen verbracht haben als im Frühjahr 2020, ist jedoch bislang weitgehend unbekannt.
Um zu erfahren, mit welchen Aktivitäten die Schulkinder die Zeit der Schulschließungen Anfang 2021 verbracht haben, wurde erneut eine deutschlandweite Umfrage durchgeführt, diesmal unter mehr als 2.000 Eltern von Schulkindern. Die Ergebnisse liefern umfassende Einblicke in den Alltag von Schulkindern, Eltern und Schulen während der Schulschließungen Anfang 2021. Sie zeigen, wie viele Stunden die Schulkinder in dieser Phase mit Lernen und anderen kreativen und passiven Tätigkeiten verbracht haben, welche konkreten Maßnahmen die Schulen ergriffen haben, um den Schulbetrieb aufrechtzuerhalten, wie effektiv das Lernen zu Hause war, und wie die Eltern das häusliche Lernumfeld einschätzen. Dabei vergleichen wir die Aktivitäten während der Schulschließungen Anfang 2021 mit den Aktivitäten während der ersten Corona-bedingten Schulschließungen im Frühjahr 2020 sowie mit den Aktivitäten vor Corona (vgl. Wößmann et al., 2020). Wir berichten zudem Ergebnisse zum sozio-emotionalen Wohlbefinden der Kinder nach einem Jahr Coronapandemie und zu den Einschätzungen der Eltern, welche breiteren Auswirkungen die Schulschließungen auf verschiedene Lebensbereiche ihrer Kinder haben. Die Befragung liefert somit neue empirische Erkenntnisse über mögliche Folgen der Corona-Krise für den Bildungserfolg von Kindern in Deutschland. Dabei untersuchen wir auch, inwiefern sich die Auswirkungen der Schulschließungen zwischen leistungsstärkeren und -schwächeren Schülerinnen und Schülern sowie zwischen Akademikerkindern und Nicht-Akademikerkindern unterscheiden.
Auf dem Weg zu einer neuen Normalität in Schule und Bildung?! : Empfehlungen der Beitragenden
(2023)
Die im vorliegenden Band präsentierten Studien und Erkenntnisse zeigen die tiefen Einschnitte, die die Pandemie in Schule und Bildung hinterlassen hat. Zahlreiche Forschende, Expertinnen und Experten, aber auch engagierte Eltern, Kinder und Jugendliche wünschen sich in Anbetracht der Erfahrungen eine „neue“ Normalität für Schule und Bildung – eine Normalität, in der Bildungsungerechtigkeit wirksamer begegnet wird, die digitaler ist, … Wie könnte der Weg dahin aussehen?
Die Gewinnung und Bindung qualifizierter MINT-Mitarbeitender (Mathematik, Informatik, Naturwissenschaft und Technik) gehört zu den Herausforderungen des Personalmanagements, gerade in Bezug auf den weiblichen MINT-Nachwuchs. Spannend ist die Frage, ob Frauen Arbeitgebermerkmale anders gewichten als Männer und sich geschlechtsspezifische Präferenzen bei arbeitsplatzbezogenen Merkmalen auf den MINT-Kontext übertragen lassen. Eine empirische Untersuchung mit Studierenden technischer Studiengänge liefert Ansatzpunkte für die zielgruppenspezifische Gestaltung von Employer-Branding-Kampagnen und Rekrutierungsaktivitäten.
Resilienz gewinnt für produzierende Unternehmen immer mehr an Bedeutung. Es fehlen jedoch geeignete Maßzahlen, um ein Produktionssystem auf dessen Resilienzfähigkeit zu analysieren. Dieser Beitrag stellt Resilienzmessgrößen vor, welche es ermöglichen verschiedene Produktionssysteme zu vergleichen und zusätzlich Optimierungsmaßnahmen zu bewerten.
Condition monitoring supported with artificial intelligence, cloud computing, and industrial internet of things (IIoT) technologies increases the feasibility of predictive maintenance. However, the cost of traditional sensors, data acquisition systems, and the required information technology expert-knowledge challenge the industry. This paper presents a hybrid condition monitoring system (CMS) architecture consisting of a distributed, low-cost IIoT-sensor solution. The CMS uses micro-electro-mechanical system (MEMS) microphones for data acquisition, edge computing for signal preprocessing, and cloud computing, including artificial neural networks (ANN) for higher-level information processing. The system's feasibility is validated using a testbed for reciprocating linear-motion axes.
Machine failures’ consequences – a classification model considering ultra-efficiency criteria
(2023)
To strive for a sustainable production, maintenance has to evaluate possible machine failure consequences not just economically but also holistically. Approaches such as the ultra-efficiency factory consider energy, material, human/staff, emission, and organization as optimization dimensions. These ultra-efficiency dimensions can be considered for analyzing not only the respective machine failure but also the effects on the entire production system holistically. This paper presents an easy to use method, based on a questionnaire, for assessing the failure consequences of a machine malfunction in a production system considering the ultra-efficiency dimensions. The method was validated in a battery production.
Using predictive maintenance, more efficient processes can be implemented, leading to fewer maintenance costs and increased availability. The development of a predictive maintenance solution currently requires high efforts in time and capacity as well as often interdisciplinary cooperation. This paper presents a standardized model to describe a predictive maintenance use case. The description model is used to collect, present, and document the required information for the implementation of predictive maintenance use cases by and for different stakeholders. Based on this model, predictive maintenance solutions can be introduced more efficiently. The method is validated across departments in the automotive sector.
The increasing complexity and need for availability of automated guided vehicles (AGVs) pose challenges to companies, leading to a focus on new maintenance strategies. In this paper, a smart maintenance architecture based on a digital twin is presented to optimize the technical and economic effectiveness of AGV maintenance activities. To realize this, a literature review was conducted to identify the necessary requirements for Smart Maintenance and Digital Twins. The identified requirements were combined into modules and then integrated into an architecture. The architecture was evaluated on a real AGV on the battery as one of the critical components.
Sprachassistenten gewinnen als Alltagshelfer immer mehr an Bedeutung. Sie beeinflussen die Art und Weise, wie Menschen Aufgaben erledigen und mit Unternehmen interagieren. Eine qualitative Studie hat die Nutzungsbereitschaft beim Kauf von High-Involvement-Produkten über Sprachassistenten untersucht. Zukünftig könnte Voice Commerce für diese Produkte an Relevanz gewinnen.
This book examines the implementation of the Belt and Road Initiative (BRI) in East Africa. The BRI is considered China's central geopolitical and geo-economic project in the era of President Xi Jinping. Through this work, the author aims to contribute to filling some research gaps, such as the lack of depth in studies of individual BRI projects and the underconsideration of processing narratives in participating countries. The guiding question is the extent to which the BRI is a political or hegemonic project of the CCP-directed state-civil society complex in East Africa. To answer these questions, databases of international organizations and policy documents are analyzed. In addition, the author conducts a qualitative content analysis of newspaper articles from local media houses in the countries of Ethiopia, Kenya, and Tanzania to examine three infrastructure projects. The work illustrates that the BRI contributes to increasing connectivity in East Africa. At the same time, the compression of economic relations and the implementation of infrastructure projects in East Africa lead to numerous consequences and contour a hegemonic project.
Purpose
The authors study the valuation effect of corporate diversification in the initial phase of the COVID-19 pandemic in 2020 in Europe.
Design/methodology/approach
Applying a cross-sectional regression model to a sample of public companies headquartered in the European Union, the authors investigate the existence of and the change in a diversification discount between 2018 and 2020. By applying the Excess Q methodology, the authors make an industry adjustment of diversified companies to measure the value effect of corporate diversification.
Findings
The authors find an economically and statistically significant diversification discount that increases from an average Excess Q of −0.05 in 2019 to −0.10 in 2020. The diversified companies' inferior fundamental financial performance in 2020 accompanies the discount. The results deviate from those of previous research, which mostly show a decrease in the diversification discount in economic crises, and thereby, shed doubt on whether diversification provides insurance against pandemic-induced adverse value effects.
Originality/valueThe study distinguishes the role of corporate diversification during recessionary periods by establishing that the valuation effect of diversification depends on the nature of the crisis. The analysis incorporates criticism of previous studies concerning a biased methodology and uniform data source by applying the Excess Q methodology and using FactSet industry segment data.
Student-faculty interactions that promote learning are essential contributors to student retention, academic success and satisfaction. But the factors that causally initiate and frame these interactions are not well understood. Only if students evaluate these interactions as positive will they seek them. We conducted a survey experiment with students (n = 375) from a tuition-fee-free German business school, using conditional process analysis to assess which factors frame effective interactions. We focus on out-of-classroom standard and non-standard requests that students make to faculty, then investigate how faculty and student gender and students’ academic entitlement influence the interaction. Our study examines how students evaluate the interaction with faculty: when they seek interaction, their expectations of getting their requests approved, and their disappointment when their requests are declined. We find a significant influence of the request type along with moderating effects of faculty gender, student gender and student entitlement, particularly for non-standard work requests. We conclude with policy implications for university management: developing target-group-specific measures that facilitate the desired and positively evaluated student-faculty interactions might benefit all university stakeholders.
Cyber-Physical Production Systems increasingly use semantic information to meet the grown flexibility requirements. Ontologies are often used to represent and use this semantic information. Existing systems focus on mapping knowledge and less on the exchange with other relevant IT systems (e.g., ERP systems) in which crucial semantic information, often implicit, is contained. This article presents an approach that enables the exchange of semantic information via adapters. The approach is demonstrated by a use case utilizing an MES system and an ERP system.
Do Chinese subordinates trust their German supervisors? A model of inter-cultural trust development
(2023)
In this qualitative study based on 95 interviews with Chinese subordinates and their German supervisors, we inductively develop a model which advances theoretical understanding by showing how inter-cultural trust development in hierarchical relationships is the result of six distinct elements: the subordinate trustor’s cultural profile (cosmopolitans, hybrids, culturally bounds), the psychological mechanisms operating within the trustor (role expectations and cultural accommodation), and contextual moderators (e.g., country context, time spent in foreign culture, and third-party influencers), which together influence the trust forms (e.g., presumptive trust, relational trust) and trust dynamics (e.g., trust breakdown and repair) within relationship phases over time (initial contact, trust continuation, trust disillusionment, separation, and acculturation). Our findings challenge the assumption that cultural differences result in low levels of initial trust and highlight the strong role the subordinate’s cultural profile can have on the dynamics and trajectory of trust in hierarchical relationships. Our model highlights that inter-cultural trust development operates as a variform universal, following the combined universalistic-particularistic paradigm in cross-cultural management, with both culturally generalizable etic dynamics, as well as culturally specific etic manifestations.
In a recently developed study programme at Reutlingen University, which focuses on practical orientations, an innovative product with solid company references is to be defined and realised by student teams. On the basis of this product, all subjects of the business engineering study programme “Sustainable Production and Business” are taught. By focusing on three main paths of future skills that have been developed by NextSkills to analyse upcoming social changes, global challenges and fields of work that are innovation-driven and agile, the new study programme aims to create responsible leaders who will shape global businesses respectfully. Thereby, different TRIZ tools help to support students in developing their own products with a focus on sustainability and pay off on the future skills enhancement. Further, students get to know TRIZ tools in an unbiased way, unburdened by too much theory, and are thus continuously supported in the progressing product development process that accompanies their studies. Hence, students perceive TRIZ on the one hand as a method to develop sustainable products and, on the other hand, to find sustainable solutions for everyday problems. The knowledge and positive experiences gained in this way should then arouse curiosity for the TRIZ class at the end of the study programme. The students can graduate with a TRIZ Level 1 certificate. Thereby, as many students as possible are introduced to the TRIZ methods, and the TRIZ tool is spread widely.
Vor mehr als einem Jahrzehnt stellten die Autoren dieses Beitrags die folgende Denkaufgabe:
“Imagine the business of sports without fans. No spectators at sports matches, no buyers of merchandising, no potential customers for sponsoring companies, no recipients for the sports media. Such a scenario would be unthinkable.“ (Bühler & Nufer, 2010, S. 63)
Während der Corona-Pandemie 2020/21 wurde das Undenkbare dann aber doch Realität, als Zuschauer auf der ganzen Welt keine Sportveranstaltungen mehr besuchen durften. Das größte Sportevent der Welt, die Olympischen Spiele in Tokio 2020, mussten verschoben werden und fanden ein Jahr später unter nicht wirklich besseren Bedingungen vor so gut wie leeren Rängen statt. Das Gleiche galt für die UEFA EURO 2020, die ebenfalls um ein Jahr verschoben werden musste, dann aber zumindest (bis auf wenige Ausnahmen wie beispielsweise das Finale in Wembley) mit reduzierter Zuschauerzulassung stattfinden konnte. Hintergrund der Überlegungen sowohl des Internationalen Olympischen Komitees wie auch der Europäischen Fußballunion war damals die Befürchtung, dass ihre jeweiligen Premiumprodukte ohne Fans in den Stadien leiden würden. Natürlich gab es immer noch Millionen von Menschen, die Live-Streams von Sportveranstaltungen verfolgten oder in diesen schwierigen Corona-Zeiten allerhand Merchandise ihrer Lieblingsmannschaften kauften. Doch die Pandemie bestätigte einmal mehr die Grundregel im Sportbusiness: Der Wirtschaftsmarkt Sport im Allgemeinen und professionelle Sportorganisationen im Besonderen brauchen Fans, die bereit sind, ihre Zeit, ihre Emotionen und ihr Geld für ihren Lieblingssport und ihre Lieblingsmannschaften zu investieren. Zuschauer sind die primären – und wohl wichtigsten – Kunden eines Sportunternehmens. Daher ist es für jede professionelle Sportorganisation unerlässlich, eine nachhaltige Beziehung zu ihren Fans aufzubauen und aufrechtzuerhalten und sie auf jede mögliche Weise einzubeziehen. Vor diesem Hintergrund wird die Bedeutung des Fan-Engagements deutlich.
Sponsoring zählt zu den nicht-klassischen Formen der Marketing-Kommunikationspolitik und spricht Menschen in nicht-kommerziellen Situationen an. Gerade durch Sponsoring können Zielgruppen erreicht werden, die z.B. Werbung gegenüber negativ eingestellt oder durch klassische Kommunikationsinstrumente nicht erreichbar sind. Auch wird ein Sponsoringengagement i.d.R. eher akzeptiert als klassische Werbung, da dem Sponsoring per se eine gewisse Förderabsicht zugrunde liegt. In diesem Kapitel werden die wesentlichen Sponsoring-Grundlagen vorgestellt und das Kommunikationsinstrument Sportsponsoring sowohl aus der Perspektive von Sponsoren als auch aus der Sicht von Gesponserten genau beleuchtet. Zusätzlich werden die Besonderheiten des Sportevent-Sponsorings aufgezeigt und Ambush Marketing als Alternative zum Sportsponsoring präsentiert. Abschließend wird auf aktuelle Entwicklungen im Sportsponsoring im Rahmen der FIFA Fußball-Weltmeisterschaft 2022 und der bevorstehenden EURO 2024 eingegangen.
This article examines the risks and societal costs associated with flexible average inflation targeting in the United States and symmetric inflation targeting in the Eurozone. Employing an empirical approach, we analyze monthly cumulative inflation gaps over a monetary policy horizon of 36 months. By investigating the trajectories of the cumulative inflation gaps, we find a heavy tailed distribution and a 20 percent probability of over- and undershooting the inflation target. We exhibit that the offsetting mechanism introduced in the revised monetary strategies lack credibility in ensuring price stability during a period of persistent inflation. Consequently, the credibility of central banks may be compromised. The policy implications are the integration of an escape clause and prompt monetary corrections in cases where the inflation goal is not achieved. This study provides insights for policymakers and central banks, emphasizing challenges in maintaining credibility and price stability within the new monetary strategies.
„Tue Gutes und rede darüber“ lautet eine leicht verständliche Ur-Definition von Öffentlichkeitsarbeit, die längst zu einem Sprichwort geworden ist. Im Laufe der Zeit kamen auf die Public Relations zahlreiche Veränderungen zu: Die Sozialen Medien bewirkten, dass der interaktive Dialog und das Zuhören in den Fokus der PR rückten: „Tue Gutes und lasse andere darüber reden“ war die hierzu passende Aktualisierung. Einer der jüngsten Trends in der PR ist die Nachhaltigkeitskommunikation, die sogenannte „Green PR“, das heißt die Umsetzung glaubwürdiger, nachhaltiger Kommunikationsstrategien. Damit erfährt das Sprichwort ein weiteres Update zu „Tue nachhaltig Gutes und lasse andere dabei mitreden.“

Unternehmertum spielt sowohl für die Entwicklung afrikanischer Länder eine Rolle, als auch für ausländische Unternehmen mit Markteintrittsplänen. Die infrastrukturellen und institutionellen Rahmenbedingungen für Unternehmertum sind nach wie vor schwierig, wobei aber die fortschreitende Digitalisierung zu einer zunehmend aktiven Start-Up Szene in vielen afrikanischen Ländern führt. Nach wie vor existiert ein Mismatch zwischen den Bereichen in denen Start-Ups entstehen und den Bereichen, wo ausländische Unternehmen Partner für den Markteintritt suchen. Somit bleibt es trotz positiver Entwicklung beim Unternehmertum in absehbarer Zeit schwierig adäquate Partner zu finden.
The aim of this article is to establish a stochastic search algorithm for neural networks based on the fractional stochastic processes {𝐵𝐻𝑡,𝑡≥0} with the Hurst parameter 𝐻∈(0,1). We define and discuss the properties of fractional stochastic processes, {𝐵𝐻𝑡,𝑡≥0}, which generalize a standard Brownian motion. Fractional stochastic processes capture useful yet different properties in order to simulate real-world phenomena. This approach provides new insights to stochastic gradient descent (SGD) algorithms in machine learning. We exhibit convergence properties for fractional stochastic processes.
This article provides a stochastic agent-based model to exhibit the role of aggregation metrics in order to mitigate polarization in a complex society. Our sociophysics model is based on interacting and nonlinear Brownian agents, which allow us to study the emergence of collective opinions. The opinion of an agent, x i (t) is a continuous positive value in an interval [0, 1]. We find (i) most agent-metrics display similar outcomes. (ii) The middle-metric and noisy-metric obtain new opinion dynamics either towards assimilation or fragmentation. (iii) We show that a developed 2-stage metric provide new insights about convergence and equilibria. In summary, our simulation demonstrates the power of institutions, which affect the emergence of collective behavior. Consequently, opinion formation in a decentralized complex society is reliant to the individual information processing and rules of collective behavior.
The paper “focuses on the critique of economic rationality” (p. 2). The author analyses the work by Amartya Sen with a somewhat interdisciplinary approach. The author concludes that Sen has greatly shifted our paradigm of economic rationality. The nexus of ethics and economics as well as the two types of rationality (consistency versus optimization) are major contributions of Sen, according to the author. In a nutshell, Sen’s work is reconfiguring economic rationality until today.
Climate change is one of the key challenges of this century due to its impact on society and the economy. Students are asking their business schools to scale up climate change education (CCE) across all disciplines, and employers are looking for graduates ready to work on solutions. This desire for solutions is shared by faculty; however, in a recent survey, many highlighted that they lack knowledge about climate change mitigation and how to integrate CCE into their disciplines.
This chapter supports lecturers, professors and senior management in their journey to get an overview of CCE and, more importantly, to find high-impact climate solutions to be integrated and assessed in their teaching units.
Die meisten Innovationsprojekte in Unternehmen scheitern nicht am Mangel an Ideen, Kreativität oder am Umsetzungswillen, sondern an vielen kleinen Hürden, die die Projekte massiv entschleunigen. So verlieren Initiativen an der Dynamik, die dafür sorgt, dass sich zügig Erfolge einstellen. Ein Bereich, in dem unkonventionell, agil und schnell Ergebnisse erzielt werden, ist das Guerilla Marketing. Was können Innovations-, Forschungs- und Projektleiter aus dem Methodenbaukasten lernen? Wie können konkrete Taktiken aus dem Marketing auch Innovationsprojekten zu mehr Viralität und Schwung verhelfen, um die Eigendynamik der Initiativen „unbremsbar“ zu machen? Das erfahren Sie in diesem essential.
In the context of Industry 4.0, intralogistics faces an increasingly complex and dynamic environment driven by a high level of product customisation and complex manufacturing processes. One approach to deal with these changing conditions is the decentralised and intelligent connectivity of intralogistics systems. However, wireless connectivity presents a major challenge in the industry due to strict requirements such as safety and real-time data transmission. In this context, the fifth generation of mobile communications (5G) is a promising technology to meet the requirements of safety-critical applications. Particularly, since 5G offers the possibility of establishing private 5G networks, also referred to as standalone non-public networks. Through their isolation from public networks, private 5G networks provide exclusive coverage for private organisations offering them high intrinsic network control and data security. However, 5G is still under development and is being gradually introduced in a continuous release process. This process lacks transparency regarding the performance of 5G in individual releases, complicating the successful adoption of 5G as an industrial communication. Additionally, the evaluation of 5G against the specified target performance is insufficient due to the impact of the environment and external interfering factors on 5G in the industrial environment. Therefore, this paper aims to develop a technical decision-support framework that takes a holistic approach to evaluate the practicality of 5G for intralogistics use cases by considering two fundamental stages. The first of these analyses technical parameters and characteristics of the use case to evaluate the theoretical feasibility of 5G. The second stage investigates the application's environment, which substantially impacts the practicality of 5G, for instance, the influence of surrounding materials. Finally, a case study validates the proposed framework by means of an autonomous mobile robot. As a result, the validation proves the proposed framework's applicability and shows the practicality of the autonomous mobile robot, when integrating it into a private 5G network testbed.
Die vorliegende Studie beschäftigt sich mit der Verbreitung des Customer-Success-Managements im deutschsprachigen Mittelstand und der Frage, wie eine erfolgreiche Implementierung dort durchgeführt werden kann. Die Ergebnisse zeigen, dass, vorgelagert zum eigentlichen Customer-Success-Management-Prozess, interne sowie externe Voraussetzungen im deutschsprachigen Mittelstand geschaffen werden müssen, um eine nachhaltige Implementierung gewährleisten zu können. Dazu zählt die Transformation vom reinen Produktfokus hin zu einer kunden- und servicezentrierten Unternehmensstrategie. Voraussetzung dafür ist die Erhöhung des Digitalisierungsgrads der Produkte und internen Prozesse sowie ein aktives Change-Management.
Framework for integrating intelligent product structures into a flexible manufacturing system
(2023)
Increasing individualisation of products with a high variety and shorter product lifecycles result in smaller lot sizes, increasing order numbers, and rising data and information processing for manufacturing companies. To cope with these trends, integrated management of the products and manufacturing information is necessary through a “product-driven” manufacturing system. Intelligent products that are integrated as an active element within the controlling and planning of the manufacturing process can represent flexibility advantages for the system. However, there are still challenges regarding system integration and evaluation of product intel-ligence structures. In light of these trends, this paper proposes a conceptual frame-work for defining, analysing, and evaluating intelligent products using the example of an assembly system. This paper begins with a classification of the existing problems in the assembly and a definition of the intelligence level. In contrast to previous approaches, the analysis of products is expanded to five dimensions. Based on this, a structured evaluation method for a use case is presented. The structure of solving the assembly problem is provided by the use case-specific ontology model. Results are presented in terms of an assignment of different application areas, linking the problem with the target intelligence class and, depending on the intelligence class of the product, suggesting requirements for implementation. The conceptual frame-work is evaluated by utilising a case study in a learning factory. Here, the model-mix assembly is controlled actively by the workpiece carrier in terms of transferring the variant-specific work instructions to the operator and the collaborative robot (cobot) at the workstations. The resulting system thus enables better exploitation of the poten-tials through less frequent errors and shorter search times. Such an implementation has demonstrated that the intelligent workpiece carrier represents an additional part for realising a cyber-physical production system (CPPS).
