Knapper werdende Mittel im Gesundheitsbereich zwingen Krankenhäuser zu einer stetigen Effizienzsteigerung. Fluktuierende Rahmenbedingungen erfordern ein hohes Maß an Flexibilität. Innovation und Rationalisierung bestimmen das Vokabular der Mitarbeiter. Dabei geht es nicht um die Maximierung des Gewinns, sondern in vielen Bereichen um das Überleben eines Krankenhauses. Was sich der soziale Bereich nicht leisten kann, ist der Verzicht auf die Ideen seiner Mitarbeiter. Konventionelles, in der Industrie verwurzeltes Ideenmanagement lässt sich nicht einfach auf den Krankenhausalltag übertragen. Dieser Beitrag bietet eine Analyse des ökonomischen Denkens von Krankenhauspersonal.

JF - Zeitschrift für Gesundheitsökonomie und Qualitätsmanagement N2 - Zielsetzung: Die Bewertung ökonomischer Effizienzmechanismen des Krankenhauspersonals unterscheidet sich von anderen Berufs- und Bevölkerungsgruppen grundlegend. Inwiefern dies Auswirkungen auf die Bereitschaft zur Effizienzsteigerung und Kosteneinsparung hat, ist Gegenstand dieser Untersuchung. Methodik: Im Zuge der Untersuchung wurden in einer zweistufigen Evaluation die Mitarbeiter quantitativ und die Führungs- und Funktionskräfte im Rahmen eines qualitativen Leitfadeninterviews befragt. Ergebnisse: Die Grundeinstellung von Krankenhausmitarbeitern ist tendenziell negativ gegenüber ökonomischen Lösungsmechanismen. Soziale Verteilungslösungen werden preislichen Allokationsverfahren vorgezogen. Schlussfolgerungen: Das Personal des Krankenhausbereichs denkt anders, insbesondere in der wesentlichen Frage der Bewertung ökonomischer Effizienz. Dabei scheint die „Nähe” zum Patienten eine entscheidende Rolle zu spielen. Je stärker ein Mitarbeiter direkt mit Patienten arbeitet (Pflegedienst, Ärztlicher Dienst) desto altruistischer und gruppendynamischer ist seine Grundeinstellung. Hierbei werden soziale Aspekte, Anerkennung und Zufriedenheit weitaus stärker gewichtet als die monetäre Dimension. Mitarbeiter des Verwaltungsbereiches besitzen eine weitaus positivere Einstellung ökonomischen Effizienzmechanismen gegenüber.

Immer mehr Menschen nutzen das Flugzeug, um ihre Mobilitätsbedürfnisse zu befriedigen. Insbesondere seit Flugreisen durch Low-Cost-Carrier für jedermann erschwinglich geworden sind, nimmt der Luftverkehr stetig zu. Die Infrastruktur am Boden kann hier seit Jahren nicht mehr mithalten. Slots – die Lande- und Startnischen für Flugzeuge – sind insbesondere an großen internationalen Flughäfen zur Mangelware geworden. Stetig drängen neue Airlines in den europäischen Luftraum und beanspruchen ihren Platz als Luftverkehrsdienstleister – und erhöhen damit die Nachfrage nach Slots. Gleichzeitig werden Restriktionen und protektionistische Regelungen im Luft- verkehr gelockert (vgl. z.B. Open Skies). Die Erkenntnis, dass der Luftverkehr zum Kitt der Globalisierung geworden ist, hat sich in den Köpfen der Menschen längst durchgesetzt. Das Hauptproblem besteht also im Kapazitätsengpass bei Slots und bei der Abfertigung der Flugzeuge am Boden. Der derzeitige Vergabemechanismus für Slots wurde in einer Zeit etabliert, in der vollständig regulierte Flughäfen die Ausnahme darstellten. Heutzutage sind vollständig regulierte bzw. partiell vollständig regulierte Flughäfen zur Regel geworden. Das Slot-Grandfathering vermag den heutigen Anstieg des Luftverkehrs nicht adäquat zu bewältigen.

Missing interfaces between information systems, user interfaces, or web applications often require many manual activities. As banks are often functionally organized into traditional departments, a process-oriented organizational structure is rarely in place. The financial industry therefore offers enormous potential for the use of robotic process automation (RPA) and the raising of potential benefits such as process-related cost savings, time reductions, and quality improvements. The aim of this chapter is to describe the tremendous opportunities that the use of RPA technology offers to the financial industry and to explain how these opportunities can be realized. Therefore, we start by explaining the challenges that progressive digitalization poses to the industry and how RPA, but also more advanced technologies (that work not only rule-based but also define own rules), such as artificial intelligence, can help to overcome them. As well as providing an overview of the various applications of RPA in the financial industry, we also provide a comprehensive case study of a relevant practical application KW - Robotic Process Automation KW - Finanzdienstleistung Y1 - 2021 ER - TY - JOUR A1 - Rötzel, Peter A1 - Pedell, Burkhard A1 - Groninger, Daniel T1 - Information load in escalation situations: combustive agent or counteractive measure? JF - Journal of Business Economics N2 - This experimental study analyzes how a key factor, information load, influences decision making in escalation situations, i.e., in situations in which decision mak- ers reinvest further resources in a losing course of action, even when accounting information indicates that the project is performing poorly and should be discontin- ued. This study synthesizes prior escalation research with information overload and investigates how different levels of information load influence the escalation of com- mitment. Our findings reveal a U-shaped effect of information load: When decision makers face negative feedback, a higher information load mitigates the escalation tendency up to a certain point. However, beyond this point, more information rein- forces the escalation tendency. Moreover, we find that the type of feedback affects self-justification, and we find a negative and significant interaction between informa- tion load and self-justification in negative-feedback cases. Thus, studies investigat- ing escalation of commitment should control for self-justification and information load when utilizing high levels of information load. Finally, in the positive-feedback condition, higher information load encourages decision makers to continue promis- ing courses of action, i.e., increases decision-making performance.

ESM has been reported to lead to unproductive ‘games of visibility’ and ‘exhibitionism’, while it has been also found to enable productive outcomes related to knowledge work and product innovation, the latter being the main reason for its wide-spread adoption. We argue that decisions to use ESM as a control instrument are not made in isolation, but as part of a set of complementary choices. We provide arguments and empirical evidence that the use of ESM as a control instrument in organizations complements the use of subjective evaluations of non-task related performance (SPE). We also show that firms that face high ESM employee concerns, have a stronger complementarity between ESM use and SPE. Additional analyses show that ESM use and performance-based pay (PBP) are also complements. Together the results imply that management control system configuration changes with the employment of ESM.

This review article analyzes the development of information overload literature in business administration and related interdisciplinary fields and provides a comprehensive and overarching overview using a bibliometric literature analysis combined with a snowball sampling approach. For the last decade, this article reveals research directions and bridges of literature in a wide range of fields of business administration (e.g., accounting, finance, health management, human resources, innovation management, international management, information systems, marketing, manufacturing, or organizational science). This review article identifies the major papers of various research streams to capture the pulse of the information overload-related research and suggest new questions that could be addressed in the future and identifies concrete open gaps for further research. Furthermore, this article presents a new framework for structuring information overload issues which extends our understanding of influence factors and effects of information overload in the decision-making process.

Generally, both the party that initiates such renegotiations and the time at which renegotiations are launched determine the outcome of the PPP’s renegotiated remuneration. This effect is moderated by the degree of contract specificity and by a decrease in demand. Specifically, when the public client initiates the renegotiation of an incomplete contractual agreement due to a decrease in demand, it can successfully reduce the remuneration of the PPP.

Whereas previous studies focus on the complexity of information, this study investigates how different quantities of information influence escalation of commitment and how information load interacts with a decision maker’s interpretation of negative feedback regarding earlier decisions. In situations in which escalation of commitment can occur, infor-mation load is relevant for decision making for two reasons. First, in escalation situations in which decision makers face negative feedback, information load exacerbates the tendency to escalate commitment. Second, when an escalation tendency is absent, information load can lead to a decision to continue a losing course of action, which can be mistaken for escalation of commitment. Furthermore, decision makers with a higher level of creativity tend to invest more than decision makers with a lower level of creativity. Surprisingly, creative decision makers do not change their behavior when facing negative consequences while less creative decision mak-ers show an escalation of commitment tendency.

Der Einsatz von Heuristiken führt allerdings häufig dazu, dass die von Entscheidungsträgern geschätzte Eintrittswahrscheinlichkeit von Risiken sehr stark von der objektiven statistischen Eintrittswahrscheinlichkeit abweicht (vgl.

The study uses survey data and a database from a large company that is one of Europe’s top performers in idea management. In addition to the idea database, this study surveys participating employees about their perceptions of fairness and their participation behavior and knowledge sharing behavior. The results show that there is a clear relationship between innovation idea value, employees’ perceptions of fairness, and employees’ participation behavior and knowledge sharing behavior. Furthermore, there is clear evidence that tenure increases the value of innovation ideas. The findings suggest a number of implications for ideation management and for the design of social networks for innovation ideas. To increase the value of innovation ideas, social networks for innovation ideas can be used if the allocation of rewards for idea providers is positively associated with the fairness perceptions of network members.

The analyzed PPPs are unique in that the German Federal Ministry of Defence, a government institution, has a dual role as a main shareholder and a major customer. Drawing on these data, the present article analyzes how a government institution influences a PPP's set of objectives and shows that the conflict of interest with respect to monetary objectives between the government institution and the PPP as a whole is low in such partnerships. Furthermore, the article examines the opportunistic behavior of PPPs in contractual renegotiations where the government institution acts as a customer. The results show that, although such behavior indeed occurs, it does not concern monetary issues, since the government institution can control the monetary objectives of PPPs in which it is a main shareholder. Third, this study also analyzes and identifies certain exogenous factors that may influence the level of opportunistic behavior exhibited by the examined PPPs, providing evidence on the causes and effects of such behavior and indicating how it can be limited by the government institution.

Neben den vielen Vorteilen der Weiterentwicklung von Managementinformationssystemen und der stetig höheren Verfügbarkeit von Informationen ist allerdings auch die Entwicklung zu betrachten, dass immer mehr Entscheidungsträger zu viele Informationen erhalten (vgl. Lohr, 2007). Quellen dieser Informationsüberlast sind das interne Berichtswesen und die schnelle und aufwandsarme Verfügbarkeit von Informationen über Managementinformationssysteme. Darüber hinaus ist die Herausforderung, auch für das Controlling, Entscheidungsträgern im Unternehmen einen optimalen Umfang an Informationen zur Verfügung zu stellen, keine reine IT-Problematik, sondern betrifft sehr stark auch die Bereiche Personalwesen und Organisation.

The empirical analysis examines public–private partnerships involving the German Federal Ministry of Defense. The main characteristic of these PPPs is the dual role of the German Federal Ministry of Defense, which appears simultaneously as public shareholder and public purchaser. The paper shows that the government institution decisively determines monetary objectives and consequently the entire system of objectives. The most important monetary objective of PPPs is cost minimization, in contrast to profit maximization, which is commonly the objective of private shareholders. By determining the monetary objectives of such partnerships, the government institution prevents the opportunistic behavior of PPPs with regard to the level of charges for goods and services, which is commonly part of renegotiations if the government institution changes the demand for goods and services. Compared to wholly government-funded public projects, PPPs offer an opportunity to use the capital, competence and economic efficiency of private economic subjects without increasing the transaction costs commonly associated with the opportunistic behavior exhibited by PPPs with regard to the level of charges.

There is empirical evidence that the influence factor “job satisfaction” plays a decisive role in public service motivation. Moreover, the influence factors “work environment” and “variable wage” have a quite low direct effect on motivation.

Dies wird vor allem im Trend hin zu stärkeren Beteiligungen in entscheidenden Bereichen der Wertschöpfungskette deutlich, wie beispielsweise im Rahmen von Beteiligungen an Zulieferunternehmen. Diese Entwicklung auf Unternehmensebene wird begleitet von einer starken Fokussierung der Controlling-Elemente in den Unternehmen auf Fragestellungen der Steuerung von Beteiligungen. Hier spielen vornehmlich die Zusammenarbeit von Zentralcontrolling und dem Controlling in einzelnen Bereichen und Beteiligungen sowie die Einbindung in die Konzernstrategie eine Rolle (vgl. Sieber et al., 2009; Littkemann, 2009). Der Vorteil von Beteiligungen gegenüber Fusionen liegt vornehmlich in dem geringen Kapitalbedarf, da bei Beteiligungen ein einfacher Mehrheitsanteil genügt und das Zielunternehmen nicht vollständig gekauft werden muss. Weitere Anwendungsfälle sind Joint Ventures, also die Gründung einer Tochtergesellschaft durch mindestens zwei rechtlich und wirtschaftlich getrennte Unternehmensmütter, sowie Public Private Partnerships.

Design/methodology/approach Based on survey data from 218 firms, the authors test a structural equation model. Findings The results show that environmental management control systems mediate the relationship between environmental strategy and environmental managerial performance. Moreover, the level of integration between regular and environmental management control systems significantly impacts the relationship between environmental management control systems and environmental managerial performance. Therefore, environmental management control systems are important mechanisms to translate environmental strategy into managerial performance, and a high level of integration can reinforce this role. Research limitations/implications The typical shortcomings of survey-based research apply to this study. Originality/value While previous research focuses primarily on environmental performance at the organizational level, this study addresses individual managerial performance with regard to environmental outcomes. In addition, the authors investigate how the level of integration between regular and environmental management control systems influences the relationship between environmental strategy and environmental managerial performance as well as the mediating role of environmental management control systems.

The regulation mandates the disclosure of information on greenhouse gas emissions, gender distribution and human rights issues. We examine two research questions: first, whether firms increased disclosure on the mandated topics after the regulation became effective relative to a control group, and second, whether a potential increase in disclosure is moderated by firms’ reporting incentives, namely, firms’ capital market visibility, growth orientation, governance structure, prior voluntary sustainability disclosure levels and critical media coverage. Our sample consists of the FTSE-350 firms and a matched control group of US firms. We use textual analysis to assess the disclosure of the mandated sustainability topics in firms’ annual reports. Specifically, we examine two types of disclosure, namely, the disclosure of the mandated key performance indicators and the narrative disclosure. Our results reveal a significant increase for both types of disclosure relative to the control group. Overall, this treatment effect tends to be smaller for firms with higher reporting incentives, i. e., reporting incentives mitigate the regulatory effect. Taken together, our results suggest that both standards and reporting incentives shape firms’ sustainability disclosure level.

This study empirically examines the mediating role of information (over-)load on the relationships between two system features (deep structure usage and system quality) and managerial performance using a mixed-method-approach (survey and interviews). It analyzes the relationships with respect to a state-of-the-art decision support system (DSS). Our results indicate that information overload adversely affects managerial performance and mediates the influence of system quality and deep structure usage on managerial performance. We find that system quality is positively related to information overload. Drawing on cognitive load theory, we hypothesize and confirm that deep structure usage reduces perceived information overload. Additional evidence from interviews further illustrate these results and show that information overload can be influenced in counter-intuitive ways by system aspects. Our results have important implications for the design of modern information system (IS) landscapes to support managerial performance. They draw attention to the importance of information overload as a mediating factor in the interrelationship among deep structure usage, system quality and managerial performance.

Knowledge on cultural differences may help international corporations to adapt management practices according to the markets they are operating in. The purpose of this paper is to study the issue of escalation of commitment and framing in a new cultural setting involving Germany and Vietnam. This setting is unique and particularly interesting, for Germany being the biggest European market and Vietnam being one of the fastest growing emerging markets in Asia. Design/methodology/approach The authors use a lab experiment with student participants from Germany and Vietnam. Findings In a 2×2 in between-experiment, the authors find strong support that Vietnamese participants have a stronger tendency to invest additional resources and evidence that negatively framed information leads to the higher escalation of commitment. Implications are discussed. Originality/value The unique empirical comparison is important because differences between other western and eastern countries do not necessarily generalize to the setting.

Die empirische Analyse bezieht sich auf Public Private Partnerships des Bundesministeriums der Verteidigung. Diese Public Private Partnerships sind dadurch gekennzeichnet, dass der öffentliche Anteilseigner gleichzeitig als öffentlicher Auftraggeber auftritt. Zunächst wird gezeigt, dass die staatliche Institution als öffentlicher Anteilseigner das Zielsystem in Bezug auf die monetären Ziele maßgeblich bestimmt. Für die Public Private Partnerships ist demnach die Kostenminimierung und nicht die von den privaten Anteilseignern eingeforderte Gewinnmaximierung das wichtigste monetäre Ziel. Die staatliche Institution unterbindet durch die Beeinflussung der monetären Ziele einer Public Private Partnerhip das opportunistische Verhalten in Bezug auf das Entgelt für die zu erbringende Leistung. Im Vergleich zu einer rein privatwirtschaftlichen Erfüllung von öffentlichen Aufträgen ist die Etablierung von Public Private Partnerships eine Möglichkeit, das Kapital, die Kompetenz sowie die wirtschaftliche Effizienz von privaten Wirtschaftssubjekten zu nutzen, ohne die Transaktionskosten durch eine opportunistische Entgeltgestaltung maßgeblich zu erhöhen.

One reason why some firms cope more efficiently with such unexpected events than others has long been the subject of research, might be found in their resilience design. However, there is still no consensus in the literature and there is no common understanding of the definitions, the conceptualizations of resilience at the organizational level, and the interaction with management control systems (MCS). This study bridges MCS and resilience literature and provides a broader understanding of the relationship between the organization and adversity. Due to its ability to successfully control an organization and provide an effective control environment, we use Simons’ levers of control framework (LOC) as framework for integrating organizational resilience into MCS. We perform a systematic reviewing of analytical conceptualizations and definitions of management control systems (levers of control) and organizational resilience, supplemented by current empirical findings. Based on literature, we provide a framework which integrates organizational resilience into management control systems. Our findings show that the integration of resilience aspects into MCS enables firms to manage resilience at the organizational level.

Missing interfaces between Information Systems, User Interfaces or Web Applica-tions often require many manual activities. As banks are often functionally organized into traditional departments, a process-oriented organizational structure is rarely in place. The financial industry therefore offers enormous potential for the use of Robotic Process Automation (RPA) and the rais-ing of potential benefits such as process-related cost savings, time reductions and quality im-provements. The aim of this chapter is to describe the tremendous opportunities that the use of RPA technology offers to the financial industry and to explain how these opportunities can be realized. Therefore, we start by explaining the challenges that progressive digitalization poses to the industry and how RPA, but also more advanced technologies (that work not only rule-based but also define own rules), such as Artificial Intelligence (AI), can help to overcome them. As well as providing an over-view of the various applications of RPA in the financial industry, we also provide a comprehensive case study of a relevant practical application.

Such sentiment can potentially explain developments in regulation and may be indirectly associated with the buildingof defense mechanisms of cyber-victims. Results show that the quantity of reports on cyber-attacks on firms has been increasing,but the sentiment of reports on cyber-attacks has been decreasing. Both trends reflect the increasing severity of the issue and arelikely contributing to regulatory responses. Results also show that the sentiment is conditional to the source that reports the cyber-attack.

As a multidimensional concept, sustainability accounting, however, relates to various other disciplines and thus provides a suitable setting to examine the extent of interdisciplinarity in accounting research. This paper investigates sustainability accounting in in twofold way. First, it provides a comprehensive and systematic review of academic literature addressing sustainability accounting topics. Based on a systematic search strategy capturing articles in the fields of finance and accounting, management, economics, organization and behavioral research, and international business, we determine a sample of 5,245 articles. Descriptive findings show that equally large proportions of the sample articles are published in accounting, management, and organization journals. Using citation network analysis, we identify existing research clusters within this sample and analyse them with respect to their delineations and interactions. Our results reveal that cluster formation relates to specific subject areas with some clusters showing limited interactions to other subject areas, while other clusters are more “interdisciplinary”. Interviews with influential researchers from the most prominent clusters in the network complement the network analysis results, providing insights into the establishment of paradigms and patterns in academic research that lead to the failure of knowledge integration and impede the transfer of research insights into business and politics.

Although there are already research streams examining the interaction of AI and humans (e.g. the stream on "hybrid intelligence"), there are still numerous open research gaps – for example, a comprehensive overview of which factors favor the intention to use AI is missing. By conducting a systematic literature review, we identify the factors that potentially positively influence AI usage intentions for decision-making processes in organizations. From this, we create a framework that both provides practical implications for the successful use of AI in organizational decision-making processes and delivers further research approaches, for example, on the validity/ usability of proven IS adoption models in the present context.

While previous research starts the debate by beginning with first-year economics students, we aim to evaluate pre-firstyear individuals, i.e., school pupils. Drawing on the seminal works of Haucap, J., & Just, T. (2010). Not guilty? Another look at the nature and nurture of economics students. European Journal of Law and Economics, 29(2), 239–254 and Frey, B. S., Pommerehne,W.W., & Gygi, B. (1993). Economics indoctrination or selection? Some empirical results. The Journal of Economic Education, 24(3), 271–281, we investigate a sample of pupils ranging from the 5th to the 13th grades to determine whether pupils are “born economists” (nature), develop economic thinking (nurture), or both. We find that young individuals start to think differently in early grades and that their thinking and attitudes are shaped differently throughout their school careers, thereby providing support for the effects of both nature and nurture. Our findings show that school time impacts fairness judgments, particularly regarding price mechanisms. Regarding learning or indoctrination, we find that economics-inclined pupils are positively affected by lessons in economics in school, while pupils who are economics-averse draw completely diametric conclusions from economics lessons, thereby exhibiting increased disapproval of price allocation over the course of these classes and increased approval of the first come, first served and governmental action mechanisms.Moreover, we find strong effects of gender and migration background in this context. This study is the first to elucidate the development of economic thinking in 5th–13th grade pupils. Our results are important for economists, educators, and researchers because they can serve as a starting point for subsequent investigations in this under-researched field.

However, trust in AI-based decision support systems (DSSs), similar to other information systems, is important for successful integration. A disruptive phenomenon, “algorithm aversion”, can impede AI trust and, thus, acceptance. Although AI recommendations outperform human recommendations in different decision-making fields, individuals underweight recommendations from AI-based DSSs compared to human decision-makers due to a lack of AI trust. We conducted a lab experiment to investigate the role of AI recommendations in workplace-related tasks, first focusing on the mediating effect of AI trust and the negative impact of algorithm aversion on decision-making performance and the moderating effect of technical competence. Second, we analyzed the ability of gamification to reduce this phenomenon. We provide evidence regarding how to enhance decision-making performance when AI recommendations are deployed and identify countermeasures against algorithm aversion to facilitate the adoption of AI-based DSSs.

The paper delves into the criticality of trust in AI-based Decision Support Systems (DSSs), similar to the trust required for other (Accounting) information systems to integrate them efficiently. We explore the disruptive phenomenon known as "algorithm aversion" - a significant barrier to the trust and acceptance of AI. Although AI recommendations outperform human recommendations in different decision-making fields, there exists a tendency among individuals to underweight AI-based DSSs recommendations relative to those from human decision-makers. This underutilization is attributed to the lack of trust in AI. We conducted a laboratory experiment designed to investigate the role of AI recommendations in a workplace-related task in the field of financial accounting. The study is twofold: firstly, it examines how AI trust mediates and algorithm aversion adversely impacts decision-making performance, while also considering the moderating role of technical competence. Secondly, it investigates the potential of gamification by using means of Relative Performance Information (RPI) as a strategy to mitigate the effects of algorithm aversion. Through this experiment, we provide empirical evidence on methods to enhance decision-making performance in the context of AI recommendations. Additionally, we identify and propose counterstrategies to combat algorithm aversion, thereby facilitating the broader adoption and integration of AI-based DSSs in accounting and auditing settings. This study contributes to the accounting and auditing research community by offering insights into how AI can be more effectively incorporated into decision-making processes, addressing both psychological and technical barriers to its acceptance.

The intra-corporate information-providing process is an expert market with information asymmetry. I show that information overload occurs as an SID and is the result of informational overconsumption deliberately caused by the supplying reporter. My analysis highlights that the information overload depends on the specificity of information. It also shows that the decision maker may face a hold-up situation in light of switching costs. The more specific the information needed, the higher the threat of information overload. The strategic content of information tempts reporting managers to overload the decision maker for the purpose of increasing their reporting transfer price and to discourage the decision maker from getting the information from another reporting manager. Although the decision maker knows a part of the information demand, information overload involves the cost of using unnecessary inputs, information overload occurs as an SID of information, even if other competing reporting managers exist. My analysis demonstrates that information overload can occur due to uncertainty and opportunism of both the decision maker and reporting managers.

Wie Menschen auf KI-Entscheidungsempfehlungen reagieren T2 - Vertrauen in Künstliche Intelligenz N2 - Künstliche Intelligenz (KI) hat sich zu einer transformativen Kraft entwickelt, die verschiedene Aspekte der täglichen Arbeit beeinflusst. Es stellt sich die Frage: Können Menschen freundschaftliche Beziehungen zu KI-Entscheidungsunterstützungssystemen aufbauen oder werden diese Systeme nur als Werkzeuge betrachtet? In diesem Kapitel werden die Dynamik, die Herausforderungen und die Möglichkeiten von Mensch-KI-Interaktionen (MKI) untersucht, wobei ein besonderer Fokus auf die entscheidende Rolle des Vertrauens in dieser Interaktion gelegt wird. Das Vertrauen in KI wird durch kognitive, emotionale und soziale Faktoren beeinflusst. Zu den kognitiven Faktoren gehören die Transparenz und Interpretierbarkeit von KI-Systemen, zu den emotionalen Faktoren gehören die emotionale Bindung und das Verhältnis zwischen Menschen und KI-Agenten und zu den sozialen Faktoren gehören gesellschaftliche Normen und kulturelle Einflüsse. Das Spannungsverhältnis zwischen Automatisierungs- und Algorithmusvermeidungstendenzen stellt eine komplexe Herausforderung für MKI dar. Automatisierungsbias bedeutet, sich unhinterfragt auf KI-Empfehlungen zu verlassen. Die Tendenz zur Algorithmusvermeidung beschreibt die Ablehnung oder das Übergehen von KI-Empfehlungen zugunsten eines menschlichen Urteils. Um dieses Spannungsfeld zu bewältigen, müssen transparente und erklärbare KI-Systeme entwickelt und eine effektive Zusammenarbeit zwischen Menschen und KI gefördert werden. Durch die Berücksichtigung dieser Faktoren und die Stärkung des Vertrauens kann MKI zu einer informierteren Entscheidungsfindung und einer effektiven Nutzung der KI-Funktionen führen KW - Künstliche Intelligenz KW - Künstliche Intelligenz KW - Mensch-KI-Interaktion KW - Vertrauen Y1 - 2024 UR - https://link.springer.com/chapter/10.1007/978-3-658-43816-6_2 U6 - https://doi.org/10.1007/978-3-658-43816-6_2 SP - 17 EP - 31 PB - Springer Fachmedien CY - Wiesbaden ER - TY - JOUR A1 - Weber, Max M.

One reason some organizations cope better than others may be that their management control systems (MCSs) more effectively foster organizational resilience. Despite considerable literature on MCSs and organizational resilience, there is a lack of research on the impact of an MCS’s use on organizational resilience. This study examines and bridges the literatures on MCSs and organizational resilience to illuminate how organizations can better cope with adversity. To identify potential relationships between management controls, MCSs, and organizational resilience, we systematically review the literature and perform a content analysis. We examine the relationships between organizational resilience measures, capabilities, and management controls. We propose the use of resilience-oriented management controls and discuss whether organizations can increase their resilience by building resilience-oriented MCSs. Based on Simons’s levers of control framework and Duchek’s capability-based conceptualization of organizational resilience, we develop a conceptual organizational resilience/MCS framework. Our study reveals relationships and gaps between the literatures on MCSs and organizational resilience and proposes avenues for future research. Our findings suggest that resilience-oriented MCSs are beneficial to organizational resilience.

We implement different approaches in multiple experiments and test their predictive abilities with different financial time series. We demonstrate experimentally that both wavelet neural networks and neural networks with data pre-processed by wavelets outperform classical network topologies. However, the precision of conducted forecasts implementing neural network algorithms still propose potential for further refinement and enhancement. Hence, we discuss our findings, comparisons with “buy-and-hold” strategies and ethical considerations critically and elaborate on future prospects.

JF - Communications in Nonlinear Science and Numerical Simulation N2 - In this study, we empirically show the dynamics of daily wavelet-filtered (denoised) S&P 500 returns (2000–2020) to consist of an almost equally divided combination of stochastic and deterministic chaos, rendering the series unpredictable after expiration of the Lyapunov time, resulting in futile forecasting attempts. We achieve a clear distinction of the true nature of the underlying time series dynamics by applying a novel and combinatory chaos analysis framework comparing the wavelet-filtered S&P 500 returns with respective surrogate datasets, Brownian motion returns and a Lorenz system realisation. Furthermore, we are the first to show the strange attractor of especially the daily-frequented S&P 500 return system graphically via Takens´ embedding and by spectral embedding in combination with Laplacian Eigenmaps. Finally, we critically discuss implications and future prospects in terms of financial forecasting.
