Extending research on social factors (i.e., fear of missing out), this study considers the News Feed setup. More specifically, we suggest that the order of the News Feed (chronological vs. algorithmically assembled posts) affects usage behaviors. Against the background of the variable reward schedule, this study hypothesizes that the different orders exert serendipity differently. Serendipity, termed as unexpected lucky encounters with information, resembles variable rewards. Studies have evidenced a relation between variable rewards and excessive behaviors. Similarly, we hypothesize that order-induced serendipitous encounters affect SNS usage times and explore this link in a two-wave survey with an experimental setup (users using either chronological or algorithmic News Feeds). While theoretically extending explanations for increased SNS usage times by considering the News Feed order, practically the study will offer recommendations for relevant stakeholders.

However, this established hypothesis is increasingly being challenged, with scholars criticizing its lack of empirical support and the imprecise conceptualization of active use. Nevertheless, with considerable heterogeneity among existing studies on the hypothesis and causal evidence still limited, a final verdict on its robustness is still pending. To contribute to this ongoing debate, we conducted a week-long randomized control trial with N = 381 adult Instagram users recruited via Prolific. Specifically, we tested how active SNS use, operationalized as picture postings on Instagram, affects different dimensions of well-being. The results depicted a positive effect on users' positive affect but null findings for other well-being outcomes.

Lay Summary Active use of social networking sites (SNSs) has long been assumed to benefit users' well-being. However, this established assumption is increasingly being challenged, with scholars criticizing its lack of empirical support and the imprecise conceptualization of active use. Nevertheless, with great diversity among conducted studies on the hypothesis and a lack of causal evidence, a final verdict on its viability is still pending. To contribute to this ongoing debate, we conducted a week-long experimental investigation with 381 adult Instagram users. Specifically, we tested how posting pictures on Instagram affects different aspects of well-being. The results of this study depicted a positive effect of posting Instagram pictures on users' experienced positive emotions but no effects on other aspects of well-being. The findings broadly align with the recent criticism against the active use hypothesis and support the call for a more nuanced view on the impact of SNSs on users.

Environmental, social, and governance (ESG) issues are therefore gaining increasing importance, in line with the growing demand for corporate sustainability. ESG ratings foster the comparison of companies with respect to their sustainable practices. This study aims to investigate how ESG ratings impact financial performance in the European food industry. Ordinary least squares regression is applied to analyze the relation between ESG ratings and financial performance over a 4-year period from 2017 to 2020. The profitability measures Return on Assets (ROA) and Return on Equity (ROE) are employed as financial performance measures, while ESG ratings are obtained from the database CSRHub. Results show that higher ESG ratings are associated with better financial performance. Although the effect is modest in the present study, the findings support previous results that ESG ratings are positively related to financial performance. Nonetheless, they also highlight that ESG ratings strongly converge to the mean, which depicts the need to reassess whether ESG ratings are able to measure actual ESG behavior.

By exploring configurations of business model changes over time, we add the direction of business model changes-namely business model convergence or divergence-as a vital avenue to the business model innovation literature. We identify necessary business model convergence and divergence recipes in a sample of N = 217 strategic dyadic alliances. Firstly, technological proximity emerges as a single precondition to both converging and diverging business models. Secondly, business models between competitors either converge through complementarities or tend not to change relative to each other. Thirdly, equity participation enables business model divergence through co-specialization. We conclude with a discussion of business model trajectories and future research directions.

Design/methodology/approach Journal (co-)citation analysis, author (co-)citation analysis, institution citation and co-operation analysis, keyword co-occurrence analysis, document (co-)citation analysis and burst detection analysis were conducted based on a bibliometric data set relating to sharing economy publications. Findings Sharing economy research is multi- and interdisciplinary. Journals focused upon products liability, organizing framework, profile characteristics, diverse economies, consumption system and everyday life themes. Authors focused upon profile characteristics, sharing economy organization, social connections, first principle and diverse economy themes. No institution dominated the research field. Keyword co-occurrence analysis identified organizing framework, tourism industry, consumer behavior, food waste, generous exchange and quality cue as research themes. Document co-citation analysis found research themes relating to the tourism industry, exploring public acceptability, agri-food system, commercial orientation, products liability and social connection. Most cited authors, institutions and documents are reported. Research limitations/implications The study did not exclusively focus on publications in top-tier journals. Future studies could run analyses relating to top-tier journals alone, and then run analyses relating to less renowned journals alone. To address the potential fuzzy results concern, reviews could focus on business and/or management research alone. Longitudinal reviews conducted over several points in time are warranted. Future reviews could combine qualitative and quantitative approaches. Originality/value We contribute by analyzing information relating to the population of all sharing economy articles.

Apart from favorable traits fostering opportunity recognition, entrepreneurial orientation, venture performance, and other variables, a younger research stream also addresses the role of negative traits. Among them, the dark triad, comprising of narcissism, Machiavellianism, and psychopathy, have gained specific attention. This systematic literature review aims to structure the field, identify current research themes, and provide a better understanding of prior research outcomes. Our results show that dark triad research addresses entrepreneurial activity, opportunity recognition, entrepreneurial orientation, entrepreneurial leadership, the and entrepreneurial motives. Among the dark triad traits, narcissism is stressed most in research so far. It relates to firm performance, risk, and leadership behavior, whereas Machiavellianism and psychopathy relate to opportunity recognition and exploitation. We also identify several research gaps, which can be addressed in future research.

Es angemessen zu trainieren kann jedoch sowohl zeitaufwendig als auch kostenintensiv werden, erfordert es doch idealerweise wiederholte, persönliche Übungen mit professionellen Verhandlungsführern oder Agenten. Digitale Trainingswerkzeuge können zwar ebenfalls Trainingserfolge erzielen, bieten aber eine mangelnde Authentizität der Übungssituation und erschweren somit den Transfer des Gelernten in den Berufsalltag. Das in diesem Beitrag vorgestellte Verhandlungstraining setzt Virtual Reality (VR) als Technologie für realitätsnahe Simulation ein, um eine räumlich authentische Übungssituation zu schaffen. Weiterhin dient ein sprachlich interagierendes Dialogsystem als automatisierter, virtueller Verhandlungsagent. Dieser wurde mit Interaktionsdaten aus einer Verhandlungsstudie trainiert und bietet Trainingspersonen somit einen wirksamen Übungspartner für das VR-Verhandlungstraining.

We develop and test a model that posits that gender-diverse teams outperform gender-homogeneous teams when perceived time pressure is low, whereas the opposite is the case when perceived time pressure is high. Drawing on the categorization-elaboration model (CEM; van Knippenberg, De Dreu, & Homan, 2004), we begin with the assumption that information elaboration is the process whereby gender diversity fosters positive effects on team performance. However, also in line with the CEM, we argue that this process can be disrupted by adverse team dynamics. Specifically, we argue that as time pressure increases, higher gender diversity leads to more team withdrawal, which, in turn, moderates the positive indirect effect of gender diversity on team performance via information elaboration such that this effect becomes weaker as team withdrawal increases. In an experimental study of 142 four-person teams, we found support for this model that explains why perceived time pressure affects the performance of gender-diverse teams more negatively than that of gender-homogeneous teams. Our study sheds new light on when and how gender diversity can become either an asset or a liability for team performance.

In recent years, negotiation research did not put a lot of emphasis on external changes. Consequently, current challenges and trends are scarcely integrated, making it difficult to support negotiation practice perspectively. Design/methodology/approach: This paper applies the structured, multi-method approach of scenario analysis. To examine the future space of negotiations, this combines qualitative and quantitative measures to base our analysis on negotiation experts’ assessments, estimations and visions of the negotiation future. Findings: The results comprise an overview of five negotiation scenarios in the year 2030 and of their individual drivers. The five revealed scenarios are: digital intelligence, business as usual, powerful network – the route to collaboration, powerful network – the route to predominance and system crash. Originality/value: The scenario analysis is a suitable approach that enables to relate various factors of the negotiation environment to negotiations themselves and allows an examination of future changes in buyer–seller negotiations and the creation of possible future scenarios. The identified scenarios provide an orientation for business decisions in the field of negotiation.

They are expected to impact all areas in companies and will, therefore, most likely occur in business negotiations. Although several studies address future developments of different business divisions, the megatrends' impact on negotiations has, thus far, not been analyzed. We designed a model including the three megatrends, i.e., globalization and economic shift, digitalization and new technologies, and demographic and social change, which have main effects on specific negotiation aspects. Our study combined an online survey and expert interviews with negotiation practitioners to provide a first broad view of how megatrends affect future business negotiations. The results confirm our model and reveal a close connection of megatrends and single negotiation aspects. Among others, we examine an orientation toward global partners, an increased interconnection through various electronic systems, as well as two opposite relationship directions - long-term and integrative through strategic cooperation vs. short-term and distributive through competition and new technologies.

Work processes, services, or products must be sensibly adapted to changing times. To be able to analyze and, if necessary, adapt creativity in work processes, a precise understanding of these creative activities is necessary. Process modeling techniques are often used to capture business processes, represent them graphically and analyze them for adaptation possibilities. This has been very limited for creative work. An accurate understanding of creative work is subject to the challenge that, on the one hand, it is usually very complex and iterative. On the other hand, it is at least partially unpredictable as new things emerge. How can the complexity of creative business processes be adequately addressed and simultaneously manageable? This dissertation attempts to answer this question by first developing a precise process understanding of creative work. In an interdisciplinary approach, the literature on the process description of creativity-intensive work is analyzed from the perspective of psychology, organizational studies, and business informatics. In addition, a digital ethnographic study in the context of software development is used to analyze creative work. A model is developed based on which four elementary process components can be analyzed: Intention of the creative activity, Creation to develop the new, Evaluation to assess its meaningfulness, and Planning of the activities arising in the process – in short, the ICEP model. These four process elements are then translated into the Knockledge Modeling Description Language (KMDL), which was developed to capture and represent knowledge-intensive business processes. The modeling extension based on the ICEP model enables creative business processes to be identified and specified without the need for extensive modeling of all process details. The modeling extension proposed here was developed using ethnographic data and then applied to other organizational process contexts. The modeling method was applied to other business contexts and evaluated by external parties as part of two expert studies. The developed ICEP model provides an analytical framework for complex creative work processes. It can be comprehensively integrated into process models by transforming it into a modeling method, thus expanding the understanding of existing creative work in as-is process analyses. N2 - Kreativität – etwas Neues und Nützliches zu entwickeln – ist eine ständige Herausforderung in der Arbeitswelt. Arbeitsabläufe, Dienstleistungen oder Produkte müssen sinnvoll an den Wandel der Zeit angepasst werden. Um die Kreativität in Arbeitsprozessen analysieren und gegebenenfalls anpassen zu können, ist ein genaues Verständnis dieser kreativen Aktivitäten notwendig. Prozessmodellierungstechniken werden häufig eingesetzt, um Geschäftsprozesse zu erfassen, grafisch darzustellen und auf Anpassungsmöglichkeiten zu analysieren. Dies ist für kreative Arbeit nur sehr begrenzt möglich. Ein genaues Verständnis der kreativen Arbeit unterliegt der Herausforderung, dass sie zum einen in der Regel sehr komplex und iterativ ist. Andererseits ist sie zumindest teilweise unvorhersehbar, da immer wieder Neues entsteht. Wie lässt sich die Komplexität kreativer Geschäftsprozesse adäquat adressieren und gleichzeitig handhabbar machen? Diese Dissertation versucht, diese Frage zu beantworten, indem sie zunächst ein präzises Prozessverständnis kreativer Arbeit entwickelt. In einem interdisziplinären Ansatz wird die Literatur zur Prozessbeschreibung kreativitätsintensiver Arbeit aus der Perspektive der Psychologie, der Organisationswissenschaft und der Wirtschaftsinformatik analysiert. Darüber hinaus wird eine digital-ethnographische Studie im Kontext der Softwareentwicklung zur Analyse kreativer Arbeit herangezogen. Es wird ein Modell entwickelt, auf dessen Basis vier elementare Prozesskomponenten identifiziert werden können: Intention der kreativen Tätigkeit, Creation zur Entwicklung des Neuen, Evaluation zur Beurteilung der Sinnhaftigkeit und Planung der im Prozess anfallenden Aktivitäten - kurz: das ICEP-Modell. Diese vier Prozesselemente werden dann in die Knockledge Modeling Description Language (KMDL) überführt, die zur Erfassung und Darstellung wissensintensiver Geschäftsprozesse entwickelt wurde. Die Modellierungserweiterung auf der Grundlage des ICEP-Modells ermöglicht es, kreative Geschäftsprozesse zu identifizieren und zu spezifizieren, ohne dass eine umfangreiche Modellierung aller Prozessdetails erforderlich ist. Die hier vorgeschlagene Modellierungserweiterung wurde anhand ethnographischer Daten entwickelt und anschließend auf andere organisatorische Prozesskontexte angewendet und im Rahmen von zwei Expertenstudien von Modellierern evaluiert. Das entwickelte ICEP-Modell bietet einen analytischen Rahmen für komplexe kreative Arbeitsprozesse. Es kann durch die Umwandlung in eine Modellierungsmethode umfassend in Prozessmodelle integriert werden und erweitert so das Verständnis für bestehende kreative Arbeit in Ist-Prozess-Analysen.

In this paper, we report three studies that add to this nascent literature theoretically, methodologically, and empirically. In Study 1, we validate an effective short-form measure of global PLB using three different samples. In Studies 2 and 3, we draw on the job demands-resources model to propose that paradoxical leaders promote followers' work engagement by simultaneously fostering follower goal clarity and work autonomy. The results of survey data from Studies 2 and 3 largely confirm our model. Specifically, our findings show that PLB is positively associated with follower goal clarity and work autonomy, and that PLB exerts an indirect effect on work engagement via these variables. Moreover, our results support a hypothesized interaction effect of goal clarity and work autonomy to predict followers' work engagement, as well as a conditional indirect effect of PLB on work engagement via the interactive effect. We discuss the practical implications for leaders and organizations. Practitioner points To effectively engage followers in their work, leaders should create work environments in which followers know exactly what to do (i.e., have high goal clarity), but at the same time can determine on their own how to do their work (i.e., have high work autonomy) To foster both goal clarity and work autonomy, leaders should combine communal (e.g., other-centred, flexibility-providing) and agentic aspects of leadership (e.g., maintaining decision control and enforcing performance standards). HR departments should design leadership trainings that help leaders to combine seemingly opposing, yet ultimately synergistic behaviours.

Rather than concentrating on a specific commodity subgroup or a particular type of commodity traders, we provide an extensive overview of the behavior across all market participants and their influence on commodity prices by using a broad set of commodity futures contracts. Although commodity futures returns show co-movement with financial fundamentals (U.S. dollar index, equity, and bond markets), based on the Disaggregated Commitment of Traders Report (DCOT), this relationship cannot be attributed to trading activity. Pricing in commodity markets can be predominantly attributed to hedgers and influential speculators (money managers), whereas small speculators (nonreportable traders) are crucial to some soft commodity futures similar to dealers in metals commodity futures. Furthermore, we find limited cases where inventory changes exert a sizable influence on position changes of DCOT traders.

A1 - Schumacher, Reinhard T1 - Theory in closer contact with industrial life BT - American institutional economists on competition theory and policy JF - Journal of institutional economics N2 - This paper investigates the views on competition theory and policy of the American institutional economists during the first half of the 20th century. These perspectives contrasted with those of contemporary neoclassical and later mainstream economic approaches. We identify three distinct dimensions to an institutionalist perspective on competition. First, institutionalist approaches focused on describing industry details, so as to bring theory into closer contact with reality. Second, institutionalists emphasized that while competition was sometimes beneficial, it could also be disruptive. Third, institutionalists had a broad view of the objectives of competition policy that extended beyond effects on consumer welfare. Consequently, institutionalists advocated for a wide range of policies to enhance competition, including industrial self-regulation, broad stakeholder representation within corporations, and direct governmental regulations. Their experimental attitude implied that policy would always be evolving, and antitrust enforcement might be only one stage in the development toward a regime of industrial regulation.

By using issue analysis, negotiators become aware of their own and their opponents' preferences on negotiation issues and are able to use this knowledge to optimize their degree of success. Following research on asymmetrical preferences in negotiations, we introduce a new approach for issue analysis that considers the identification of one-sided preferences, specifically a 0-preference for issues from one party. We conducted an experimental study to test if this type of preference for an issue (chance issue) yields strategic potential for a negotiator. We also examined whether the identification of these chance issues could be particularly relevant for a low-power party in negotiations with a power imbalance, to overcome the lower scope of action due to the weaker negotiating position. The results indicate initial verification that no preference at all for one issue could lead to higher individual performance and noneconomic outcomes. Joint performance was positively affected by 0-preference, even in unbalanced power situations.

We rank the 100 institutions included with a minimum violation ranking. This ranking is positively and significantly correlated with the Times Higher Education ranking of economics institutions. According to the network ranking, individuals on average go down about 23 ranks from their doctoral institution to their employing institution. While the share of females in our dataset is only 15%, we do not observe a significant gender hiring gap (a difference in rank changes between male and female faculty). We conduct a robustness check with the Handelsblatt and the Times Higher Education ranking. According to these rankings, individuals on average go down only about two ranks. We do not observe a significant gender hiring gap using these two rankings (although the dataset underlying this analysis is small and these estimates are likely to be noisy). Finally, we discuss the limitations of the network ranking in our context.

We incorporate two related explanations, yet commonly used in different fields of literature, to explain public sector choice. First, following social learning theory, we hypothesize that parents serve as role models and thereby affect their children's sector choice. Additionally, we test the hypothesis that parental socialization leads to a longer stay in public sector jobs while assuming that it serves as a buffer against turnover. Second, following public service motivation process theory, we expect that 'interest in politics' is influenced by parental socialization and that this concept, in turn, leads to a public sector career. A representative set of longitudinal data from the Swiss household panel (1999-2014) was used to analyse these hypotheses (n = 2,933, N = 37,328). The results indicate that parental socialization serves as a stronger predictor of public sector choice than an interest in politics. Furthermore, people with parents working in the public sector tend to stay longer in their public sector jobs. Points for practitioners For practitioners, the results of this study are relevant as they highlight the limited usefulness of addressing job applicants' interest in politics in the recruitment process. Human resources managers who want to ensure a public-service-motivated workforce are therefore advised to focus on human resources activities that stimulate public service motivation after job entry. We also advise close interaction between universities and public organizations so that students develop a realistic picture of the government as a future employer and do not experience a 'reality shock' after job entry.

CY - London ER - TY - THES A1 - Böken, Björn T1 - Improving prediction accuracy using dynamic information N2 - Accurately solving classification problems nowadays is likely to be the most relevant machine learning task. Binary classification separating two classes only is algorithmically simpler but has fewer potential applications as many real-world problems are multi-class. On the reverse, separating only a subset of classes simplifies the classification task. Even though existing multi-class machine learning algorithms are very flexible regarding the number of classes, they assume that the target set Y is fixed and cannot be restricted once the training is finished. On the other hand, existing state-of-the-art production environments are becoming increasingly interconnected with the advance of Industry 4.0 and related technologies such that additional information can simplify the respective classification problems. In light of this, the main aim of this thesis is to introduce dynamic classification that generalizes multi-class classification such that the target class set can be restricted arbitrarily to a non-empty class subset M of Y at any time between two consecutive predictions. This task is solved by a combination of two algorithmic approaches. First, classifier calibration, which transforms predictions into posterior probability estimates that are intended to be well calibrated. The analysis provided focuses on monotonic calibration and in particular corrects wrong statements that appeared in the literature. It also reveals that bin-based evaluation metrics, which became popular in recent years, are unjustified and should not be used at all. Next, the validity of Platt scaling, which is the most relevant parametric calibration approach, is analyzed in depth. In particular, its optimality for classifier predictions distributed according to four different families of probability distributions as well its equivalence with Beta calibration up to a sigmoidal preprocessing are proven. For non-monotonic calibration, extended variants on kernel density estimation and the ensemble method EKDE are introduced. Finally, the calibration techniques are evaluated using a simulation study with complete information as well as on a selection of 46 real-world data sets. Building on this, classifier calibration is applied as part of decomposition-based classification that aims to reduce multi-class problems to simpler (usually binary) prediction tasks. For the involved fusing step performed at prediction time, a new approach based on evidence theory is presented that uses classifier calibration to model mass functions. This allows the analysis of decomposition-based classification against a strictly formal background and to prove closed-form equations for the overall combinations. Furthermore, the same formalism leads to a consistent integration of dynamic class information, yielding a theoretically justified and computationally tractable dynamic classification model. The insights gained from this modeling are combined with pairwise coupling, which is one of the most relevant reduction-based classification approaches, such that all individual predictions are combined with a weight. This not only generalizes existing works on pairwise coupling but also enables the integration of dynamic class information. Lastly, a thorough empirical study is performed that compares all newly introduced approaches to existing state-of-the-art techniques. For this, evaluation metrics for dynamic classification are introduced that depend on corresponding sampling strategies. Thereafter, these are applied during a three-part evaluation. First, support vector machines and random forests are applied on 26 data sets from the UCI Machine Learning Repository. Second, two state-of-the-art deep neural networks are evaluated on five benchmark data sets from a relatively recent reference work. Here, computationally feasible strategies to apply the presented algorithms in combination with large-scale models are particularly relevant because a naive application is computationally intractable. Finally, reference data from a real-world process allowing the inclusion of dynamic class information are collected and evaluated. The results show that in combination with support vector machines and random forests, pairwise coupling approaches yield the best results, while in combination with deep neural networks, differences between the different approaches are mostly small to negligible. Most importantly, all results empirically confirm that dynamic classification succeeds in improving the respective prediction accuracies. Therefore, it is crucial to pass dynamic class information in respective applications, which requires an appropriate digital infrastructure. N2 - Klassifikationsprobleme akkurat zu lösen ist heutzutage wahrscheinlich die relevanteste Machine-Learning-Aufgabe. Binäre Klassifikation zur Unterscheidung von nur zwei Klassen ist algorithmisch einfacher, hat aber weniger potenzielle Anwendungen, da in der Praxis oft Mehrklassenprobleme auftreten. Demgegenüber vereinfacht die Unterscheidung nur innerhalb einer Untermenge von Klassen die Problemstellung. Obwohl viele existierende Machine-Learning-Algorithmen sehr flexibel mit Blick auf die Anzahl der Klassen sind, setzen sie voraus, dass die Zielmenge Y fest ist und nicht mehr eingeschränkt werden kann, sobald das Training abgeschlossen ist. Allerdings sind moderne Produktionsumgebungen mit dem Voranschreiten von Industrie 4.0 und entsprechenden Technologien zunehmend digital verbunden, sodass zusätzliche Informationen die entsprechenden Klassifikationsprobleme vereinfachen können. Vor diesem Hintergrund ist das Hauptziel dieser Arbeit, dynamische Klassifikation als Verallgemeinerung von Mehrklassen-Klassifikation einzuführen, bei der die Zielmenge jederzeit zwischen zwei aufeinanderfolgenden Vorhersagen zu einer beliebigen, nicht leeren Teilmenge eingeschränkt werden kann. Diese Aufgabe wird durch die Kombination von zwei algorithmischen Ansätzen gelöst. Zunächst wird Klassifikator-Kalibrierung eingesetzt, mittels der Vorhersagen in Schätzungen der A-Posteriori-Wahrscheinlichkeiten transformiert werden, die gut kalibriert sein sollen. Die durchgeführte Analyse zielt auf monotone Kalibrierung ab und korrigiert insbesondere Falschaussagen, die in Referenzarbeiten veröffentlicht wurden. Außerdem zeigt sie, dass Bin-basierte Fehlermaße, die in den letzten Jahren populär geworden sind, ungerechtfertigt sind und nicht verwendet werden sollten. Weiterhin wird die Validität von Platt Scaling, dem relevantesten, parametrischen Kalibrierungsverfahren, genau analysiert. Insbesondere wird seine Optimalität für Klassifikatorvorhersagen, die gemäß vier Familien von Verteilungsfunktionen verteilt sind, sowie die Äquivalenz zu Beta-Kalibrierung bis auf eine sigmoidale Vorverarbeitung gezeigt. Für nicht monotone Kalibrierung werden erweiterte Varianten der Kerndichteschätzung und die Ensemblemethode EKDE eingeführt. Schließlich werden die Kalibrierungsverfahren im Rahmen einer Simulationsstudie mit vollständiger Information sowie auf 46 Referenzdatensätzen ausgewertet. Hierauf aufbauend wird Klassifikator-Kalibrierung als Teil von reduktionsbasierter Klassifikation eingesetzt, die zum Ziel hat, Mehrklassenprobleme auf einfachere (üblicherweise binäre) Entscheidungsprobleme zu reduzieren. Für den zugehörigen, während der Vorhersage notwendigen Fusionsschritt wird ein neuer, auf Evidenztheorie basierender Ansatz eingeführt, der Klassifikator-Kalibrierung zur Modellierung von Massefunktionen nutzt. Dies ermöglicht die Analyse von reduktionsbasierter Klassifikation in einem formalen Kontext sowie geschlossene Ausdrücke für die entsprechenden Gesamtkombinationen zu beweisen. Zusätzlich führt derselbe Formalismus zu einer konsistenten Integration von dynamischen Klasseninformationen, sodass sich ein theoretisch fundiertes und effizient zu berechnendes, dynamisches Klassifikationsmodell ergibt. Die hierbei gewonnenen Einsichten werden mit Pairwise Coupling, einem der relevantesten Verfahren für reduktionsbasierte Klassifikation, verbunden, wobei alle individuellen Vorhersagen mit einer Gewichtung kombiniert werden. Dies verallgemeinert nicht nur existierende Ansätze für Pairwise Coupling, sondern führt darüber hinaus auch zu einer Integration von dynamischen Klasseninformationen. Abschließend wird eine umfangreiche empirische Studie durchgeführt, die alle neu eingeführten Verfahren mit denen aus dem Stand der Forschung vergleicht. Hierfür werden Bewertungsfunktionen für dynamische Klassifikation eingeführt, die auf Sampling-Strategien basieren. Anschließend werden diese im Rahmen einer dreiteiligen Studie angewendet. Zunächst werden Support Vector Machines und Random Forests auf 26 Referenzdatensätzen aus dem UCI Machine Learning Repository angewendet. Im zweiten Teil werden zwei moderne, tiefe neuronale Netze auf fünf Referenzdatensätzen aus einer relativ aktuellen Referenzarbeit ausgewertet. Hierbei sind insbesondere Strategien relevant, die die Anwendung der eingeführten Verfahren in Verbindung mit großen Modellen ermöglicht, da eine naive Vorgehensweise nicht durchführbar ist. Schließlich wird ein Referenzdatensatz aus einem Produktionsprozess gewonnen, der die Integration von dynamischen Klasseninformationen ermöglicht, und ausgewertet. Die Ergebnisse zeigen, dass Pairwise-Coupling-Verfahren in Verbindung mit Support Vector Machines und Random Forests die besten Ergebnisse liefern, während in Verbindung mit tiefen neuronalen Netzen die Unterschiede zwischen den Verfahren oft klein bis vernachlässigbar sind. Am wichtigsten ist, dass alle Ergebnisse zeigen, dass dynamische Klassifikation die entsprechenden Erkennungsgenauigkeiten verbessert. Daher ist es entscheidend, dynamische Klasseninformationen in den entsprechenden Anwendungen zur Verfügung zu stellen, was eine entsprechende digitale Infrastruktur erfordert.

The incorporation of performance information into the budget is, however, still work in progress. Local politicians perceive the usability of non-financial information in the budget as low and do not use such information intensively for budget composition or other purposes. German municipal budgets are usually voluminous because of their highly detailed structure and the large amount of displayed performance data which rarely informs about outcomes. Such information does not meet the needs of councillors, for example in their struggles with political opponents. Some options for improving the usability of budgetary information are presented.

Specifically, we try to assess the effectiveness of the implementation of the new recovery and resolution framework in the European Union. We use a panel with daily data on European banks and sovereigns ranging from 2012 to 2016 in order to test the effects of the Bank Recovery and Resolution Directive on the two-way feedback process. We find that there was a pronounced feedback loop between banks and sovereigns from 2012 to 2014. However, after the implementation of the European Banking Union, in 2015/2016, the magnitude of the doom-loop decreased and the spillovers became not statistically significant. Furthermore, our results suggest that the implementation of the new resolution framework is a suitable candidate to explain this finding.

ECF will remain a funding technique for SMEs and small investors; it is unlikely to attract large corporations or institutional investors.

However, existing publications represent individual contributions, and we lack a holistic understanding of the value of design thinking in a digital world. No review, to date, has offered a holistic retrospection of this research. In response, in this bibliometric review, we aim to shed light on the intellectual structure of multidisciplinary design thinking literature related to capabilities relevant to the digital world in higher education and business settings, highlight current trends and suggest further studies to advance theoretical and empirical underpinnings. Our study addresses this aim using bibliometric methods—bibliographic coupling and co-word analysis as they are particularly suitable for identifying current trends and future research priorities at the forefront of the research. Overall, bibliometric analyses of the publications dealing with the related topics published in the last 10 years (extracted from the Web of Science database) expose six trends and two possible future research developments highlighting the expanding scope of the design thinking scientific field related to capabilities required for the (more sustainable and human-centric) digital world.

However, existing publications represent individual contributions, and we lack a holistic understanding of the value of design thinking in a digital world. No review, to date, has offered a holistic retrospection of this research. In response, in this bibliometric review, we aim to shed light on the intellectual structure of multidisciplinary design thinking literature related to capabilities relevant to the digital world in higher education and business settings, highlight current trends and suggest further studies to advance theoretical and empirical underpinnings. Our study addresses this aim using bibliometric methods—bibliographic coupling and co-word analysis as they are particularly suitable for identifying current trends and future research priorities at the forefront of the research. Overall, bibliometric analyses of the publications dealing with the related topics published in the last 10 years (extracted from the Web of Science database) expose six trends and two possible future research developments highlighting the expanding scope of the design thinking scientific field related to capabilities required for the (more sustainable and human-centric) digital world. Relatedly, design thinking becomes a relevant approach to be included in higher education curricula and human resources training to prepare students and workers for the changing work demands. This paper is well-suited for education and business practitioners seeking to embed design thinking capabilities in their curricula and for design thinking and other scholars wanting to understand the field and possible directions for future research.

Based on algorithms, big data analysis, machine learning, and other technologies, these services minimize the necessity for human intervention. Based on an international three-stage Delphi study, we provide a plausible forecast of the development of the robo advisor industry, with regards to market development, competition, drivers of growth, customer segments, challenges, services, technologies, and societal change. The results suggest that the financial advice market will experience a further increase in the number of robo advisor services available. Existing and traditional financial advice players will be forced to adjust to the changing environment of the market. Due to low fees and ease of use, robo advisors will be made available to a broad cross section of society, and will cause significant market losses for traditional investment advice companies. Ten years from now, the predominant investment class will remain Exchange Traded Funds (ETFs). Even though degrees of human intervention are expected to vary considering the complexity of advice, automation will increase in significance when it comes to the development of robo advisors.

BT - Evidence from rural India JF - World development N2 - In this paper, we move from the large strand of research that looks at evidence of climate migration to the questions: who are the climate migrants? and where do they go? These questions are crucial to design policies that mitigate welfare losses of migration choices due to climate change. We study the direct and heterogeneous associations between weather extremes and migration in rural India. We combine ERAS reanalysis data with the India Human Development Survey household panel and conduct regression analyses by applying linear probability and multinomial logit models. This enables us to establish a causal relationship between temperature and precipitation anomalies and overall migration as well as migration by destination. We show that adverse weather shocks decrease rural-rural and international migration and push people into cities in different, presumably more prosperous states. A series of positive weather shocks, however, facilitates international migration and migration to cities within the same state. Further, our results indicate that in contrast to other migrants, climate migrants are likely to be from the lower end of the skill distribution and from households strongly dependent on agricultural production. We estimate that approximately 8% of all rural-urban moves between 2005 and 2012 can be attributed to weather. This figure might increase as a consequence of climate change. Thus, a key policy recommendation is to take steps to facilitate integration of less educated migrants into the urban labor market.

JF - Industrial marketing management : the international journal for industrial and high-tech firms N2 - The number of alternative suppliers is widely considered to be the most important source of power in supply chains. It is common knowledge that a buying company benefits from an increasing number of suppliers until a marginalization effect occurs. Consequently, a cost-benefit optimum must exist but has not been analyzed in a sufficiently differentiated manner in the literature. Particularly, research has not taken the variety of product groups, which is reflected by the degree of innovation, into account. Using a two-way analysis of variance, this study identifies the cost-benefit optimum for the number of suppliers and analyzes the moderating role of the degree of innovation. The analysis is based on real automotive business-to-business negotiation data. The results reveal that a cost-benefit optimum is reached at a number of three suppliers at the most. Furthermore, the impact of the number of suppliers is higher for innovative products than for more functional products. Purchasing managers can use the findings to determine the optimal size of their supplier choice set.

However, digital and data-enabled innovations diffuse the market, and the COVID-19 pandemic has recently emphasized the necessity of a fundamental digital transformation. Available research indicates the relevance of digital platforms in this process but has not studied their economic impact to date. In view of this research gap and the social and economic relevance of healthcare, we explore how digital platforms might affect value creation in this market with a particular focus on Google, Apple, Facebook, Amazon, and Microsoft (GAFAM). We rely on value network analyses to examine how GAFAM platforms introduce new value-creating roles and mechanisms in healthcare through their manifold products and services. Hereupon, we examine the GAFAM-impact on healthcare by scrutinizing the facilitators, activities, and effects. Our analyses show how GAFAM platforms multifacetedly untie conventional relationships and transform value creation structures in the healthcare market.

For some people, it results in health problems, for others in productivity loss, and some experience the worst possible outcome of alcohol misuse - death. This paper estimates the effect of reduced alcohol sales hours on alcohol-attributable mortality (AAM) in Estonia. Using novel mortality data from 1997 to 2015, this paper analyzes the effect of alcohol sales policies at both the county level and the country level. By applying the difference-in-differences method and the ARIMA model, this paper finds that the alcohol sales policy reduced AAM to between 1.710 and 2.401 deaths per 100,000 per month, which equals a reduction of 31% to 40% in AAM deaths. These findings suggest that individuals who are the most at risk of dying from alcohol-attributable causes of death benefit remarkably from reduced alcohol availability.

For this purpose, an online survey was conducted in Germany, Austria and Switzerland. The result of this paper is an empirical evidence showing whether and how these factors affect the perception of potential benefits and risks expected within the context of open innovation project participation. Furthermore, the identified effects are discussed against the theory. Existing theory regarding the benefits and risks of open innovation is expanded by (1) finding that they are perceived mostly independently of the factors, (2) confirming the practical relevance of benefits and risks, and (3) enabling a finer distinction between their degrees of relevance according to respective contextual specifics.
