However, the persistence of unfavorable food preferences is a significant obstacle to changing eating behavior. Here we explored the effects of posthypnotic suggestions (PHS) on food-related decisions by measuring food choices, subjective ratings, and indifference points. In Session 1, demographic data and hypnotic susceptibility of participants were assessed. In Session 2, following hypnosis induction, PHS aiming to increase the desirability of healthy food was delivered. Afterward, a task set was administrated twice, once when PHS was activated and once deactivated. The order of PHS activation was counterbalanced across participants. The task set included a liking-rating task for 170 pictures of different food items, followed by an online supermarket where participants were instructed to select enough food for a fictitious week of quarantining from the same item pool. After 1 week, Session 3 repeated Session 2 without hypnosis induction in order to assess the persistence of PHS. The crucial dependent measures were food choices, subjective ratings, and the indifference points as a function of time and PHS condition.

Städte rückten im Zuge der Agenda 2030 in den Mittelpunkt. Ihre Verwaltungen befinden sich dabei in einem herausfordernden Spannungsfeld: Einerseits haben die SDGs den holistischen Anspruch, vollständig in das Handeln der Kommunen integriert zu werden. Andererseits ist für eine effektive Umsetzung eine starke Anpassung der SDGs an den lokalen Kontext notwendig. Die vorliegende Arbeit betrachtet anhand einer Fallstudie die Frage, wie Kommunen die Nachhaltigkeitsziele der Vereinten Nationen in ihre Handlungsprogramme und Nachhaltigkeitsstrategien übersetzen, und welche Faktoren Einfluss auf diesen Prozess haben. Dabei wird ein translationstheoretischer Ansatz verwendet, der die Übertragung einer Idee in einen lokalen Kontext als aktiven Transfer versteht, bei dem das Handeln der beteiligten Akteure und deren Konstruktion der aufzunehmenden Idee im Fokus steht. Die Translation wird mit Hilfe von qualitativen Interviews nachvollzogen und analysiert. Die Ergebnisse zeigen, dass die SDGs zwar anhand ihrer Relevanz für die Kommune gefiltert werden, der normative Anspruch der SDGs aber erhalten bleibt und angesichts des als gering beurteilten Fortschritts der Kommune besonderes Gewicht erhält. Zentrale Einflussfaktoren für die Translation sind die verfügbaren personellen und finanziellen Ressourcen, die Akzeptanz für die SDGs in Verwaltung, Politik und Gesellschaft und nicht zuletzt das persönliche Engagement einzelner Verwaltungsmitarbeiter*innen. N2 - The United Nations’ Sustainable Development Goals (SDGs) have become the leading set of guidelines for sustainability strategies on every government level. Cities are the Agenda 2030’s focal point. Their local governments however find themselves in a challenging dilemma: On the one hand, the SDG’s holistic approach warrants a wholesale integration into local policy. On the other hand, a substantial adaptation is necessary to integrate the Goals into the local context. This paper uses a case study to examine how municipalities translate the Sustainable Development Goals into their sustainability action plans and strategies. Moreover, it examines which factors are influential to this process. This study uses a translation theory perspective, which characterizes the transfer of an idea into the local context as an active process. It focusses on the actors and how they perceive the transferred idea. For this, qualitative interviews are conducted and analyzed. Thereby, this study shows that while SDGs are being filtered according to their relevancy for the municipality, their normative dimension remains intact. The municipal actors consider this dimension crucial vis-à-vis the lack of progress that they perceive in their municipality. This study finds that core influencing factors are the financial and personnel resources available, the acceptance of SDGs within the administration, politics and society as well as the activism of singular municipal actors.

Even though democratic elections not only lead to the formation of a government but also result in an opposition, the literature has mostly neglected oppositions and their role in legislative chambers. This paper proposes to fill this gap by looking at the legislative organisation from the perspective of opposition players. The paper focuses on the potential influence of opposition players in the policy-making process and presents data on more than 50 legislative chambers. The paper shows considerable variance of the formal power granted to opposition players. Furthermore, the degree of institutionalisation of opposition rights is connected to electoral systems and not necessarily correlated with other institutional characteristics such as regime type or the size of legislative chambers.

The model encompasses both the case of a common owner holding shares of rival firms as well as the case of cross ownership among rivals. We find that by softening competition, NCMS weaken the sustainability of collusion under a greater variety of situations than was indicated by earlier literature. Such effects exist, in particular, in the presence of an effective competition authority.

These must navigate and adapt to ever-shifting external and internal factors while ensuring robustness against process variabilities and unforeseen events. This has a pronounced impact on production control, which serves as the operational intersection between production planning and the shop- floor resources, and necessitates the capability to manage intricate process interdependencies effectively. Considering the increasing dynamics and product diversification, alongside the need to maintain constant production performances, the implementation of innovative control strategies becomes crucial. In recent years, the integration of Industry 4.0 technologies and machine learning methods has gained prominence in addressing emerging challenges in production applications. Within this context, this cumulative thesis analyzes deep learning based production systems based on five publications. Particular attention is paid to the applications of deep reinforcement learning, aiming to explore its potential in dynamic control contexts. Analysis reveal that deep reinforcement learning excels in various applications, especially in dynamic production control tasks. Its efficacy can be attributed to its interactive learning and real-time operational model. However, despite its evident utility, there are notable structural, organizational, and algorithmic gaps in the prevailing research. A predominant portion of deep reinforcement learning based approaches is limited to specific job shop scenarios and often overlooks the potential synergies in combined resources. Furthermore, it highlights the rare implementation of multi-agent systems and semi-heterarchical systems in practical settings. A notable gap remains in the integration of deep reinforcement learning into a hyper-heuristic. To bridge these research gaps, this thesis introduces a deep reinforcement learning based hyper- heuristic for the control of modular production systems, developed in accordance with the design science research methodology. Implemented within a semi-heterarchical multi-agent framework, this approach achieves a threefold reduction in control and optimisation complexity while ensuring high scalability, adaptability, and robustness of the system. In comparative benchmarks, this control methodology outperforms rule-based heuristics, reducing throughput times and tardiness, and effectively incorporates customer and order-centric metrics. The control artifact facilitates a rapid scenario generation, motivating for further research efforts and bridging the gap to real-world applications. The overarching goal is to foster a synergy between theoretical insights and practical solutions, thereby enriching scientific discourse and addressing current industrial challenges. N2 - Volatile Beschaffungs- und Absatzmärkte sowie eine zunehmende Produktindividualisierung konfrontieren Fertigungsunternehmen mit beträchtlichen Herausforderungen. Diese erfordern eine Anpassung der Produktion an sich ständig wechselnde externe Einflüsse und eine hohe Prozessrobustheit gegenüber unvorhersehbaren Schwankungen. Ein Schlüsselelement in diesem Kontext ist die Produktionssteuerung, die als operative Schnittstelle zwischen der Produktions- planung und den Fertigungsressourcen fungiert und eine effiziente Handhabung zahlreicher Prozessinterdependenzen sicherstellen muss. Angesichts dieser gesteigerten Produktionsdynamik und Produktvielfalt rücken innovative Steuerungsansätze in den Vordergrund. In jüngerer Zeit wurden daher verstärkt Industrie-4.0-Ansätze und Methoden des maschinellen Lernens betrachtet. Im Kontext der aktuellen Forschung analysiert die vorliegende kumulative Arbeit Deep-Learning basierte Produktionssysteme anhand von fünf Publikationen. Hierbei wird ein besonderes Augenmerk auf die Anwendungen des Deep Reinforcement Learning gelegt, um dessen Potenzial zu ergründen. Die Untersuchungen zeigen, dass das Deep Reinforcement Learning in vielen Produktionsanwendungen sowohl herkömmlichen Ansätzen als auch an- deren Deep-Learning Werkzeugen überlegen ist. Diese Überlegenheit ergibt sich vor allem aus dem interaktiven Lernprinzip und der direkten Interaktion mit der Umwelt, was es für die dynamische Produktionssteuerung besonders geeignet macht. Dennoch werden strukturelle, organisatorische und algorithmische Forschungslücken identifiziert. Die überwiegende Mehrheit der untersuchten Ansätze fokussiert sich auf Werkstattfertigungen und vernachlässigt dabei potenzielle Prozesssynergien modularer Produktionssysteme. Ferner zeigt sich, dass Multi- Agenten- und Mehr-Ebenen-Systeme sowie die Kombination verschiedener algorithmischer Ansätze nur selten zur Anwendung kommen. Um diese Forschungslücken zu adressieren, wird eine auf Deep Reinforcement Learning basierende Hyper-Heuristik für die Steuerung modularer Produktionssysteme vorgestellt, die nach der Design Science Research Methodology entwickelt wird. Ein semi-heterarchisches Multi-Agenten-System ermöglicht eine dreifache Reduktion der Steuerungs- und Optimierungs- komplexität und gewährleistet gleichzeitig eine hohe Systemadaptabilität und -robustheit. In Benchmarks übertrifft das Steuerungskonzept regelbasierte Ansätze, minimiert Durchlaufzeiten und Verspätungen und berücksichtigt kunden- sowie auftragsorientierte Kennzahlen. Die ent- wickelte Steuerungsmethodik ermöglicht einen schnellen Szenarienentwurf, um dadurch weitere Forschungsbemühungen zu stimulieren und die bestehende Transferlücke zur Realität weiter zu überbrücken. Das Ziel dieser Forschungsarbeit ist es, eine Synergie zwischen theoretischen Erkenntnissen und Praxis-relevanten Lösungen zu schaffen, um sowohl den wissenschaftlichen Diskurs zu bereichern als auch Antworten auf aktuelle industrielle Herausforderungen zu bieten.

A1 - Abrahams, Alexei T1 - How civilian attitudes respond to the state's violence BT - lessons from the Israel-Gaza conflict JF - Conflict management and peace science N2 - States, in their conflicts with militant groups embedded in civilian populations, often resort to policies of collective punishment to erode civilian support for the militants. We attempt to evaluate the efficacy of such policies in the context of the Gaza Strip, where Israel's blockade and military interventions, purportedly intended to erode support for Hamas, have inflicted hardship on the civilian population. We combine Palestinian public opinion data, Palestinian labor force surveys, and Palestinian fatalities data, to understand the relationship between exposure to Israeli policies and Palestinian support for militant factions. Our baseline strategy is a difference-in-differences specification that compares the gap in public opinion between the Gaza Strip and the West Bank during periods of intense punishment with the gap during periods when punishment is eased. Consistent with previous research, we find that Palestinian fatalities are associated with Palestinian support for more militant political factions. The effect is short-lived, however, dissipating after merely one quarter. Moreover, the blockade of Gaza itself appears to be only weakly associated with support for militant factions. Overall, we find little evidence to suggest that Israeli security policies toward the Gaza Strip have any substantial lasting effect on Gazan support for militant factions, neither deterring nor provoking them relative to their West Bank counterparts. Our findings therefore call into question the logic of Israel's continued security policies toward Gaza, while prompting a wider re-examination of the efficacy of deterrence strategies in other asymmetric conflicts.

Moving beyond the duality of personal benefits and privacy risks, we theorize that users hold social considerations (i.e., social benefits and risks) that underlie their acceptance decisions. To test our propositions, we chose the context of COVID-19 contact tracing apps and conducted a qualitative pre-study and longitudinal quantitative main study with 589 participants from Germany and Switzerland. Our findings confirm the prominence of individual privacy calculus in explaining intention to use and actual behavior. While privacy risks are a significant determinant of intention to use, social risks (operationalized as fear of mass surveillance) have a notably stronger impact. Our mediation analysis suggests that social risks represent the underlying mechanism behind the observed negative link between individual privacy risks and contact tracing apps' acceptance. Furthermore, we find a substantial intention–behavior gap.

Grundlegend für diese Veränderungen sind die neuen technologischen Möglichkeiten, Daten in immer größerem Umfang und für vielfältige neue Zwecke zu verarbeiten. Von besonderer Bedeutung ist dabei die Verfügbarkeit großer und qualitativ hochwertiger Datensätze, insbesondere auf Basis personenbezogener Daten. Sie werden entweder zur Verbesserung der Produktivität, Qualität und Individualität von Produkten und Dienstleistungen oder gar zur Entwicklung neuartiger Dienstleistungen verwendet. Heute wird das Nutzerverhalten, trotz weltweit steigender gesetzlicher Anforderungen an den Schutz personenbezogener Daten, aktiver und umfassender verfolgt als je zuvor. Dies wirft vermehrt ethische, moralische und gesellschaftliche Fragen auf, die nicht zuletzt durch populäre Fälle des Datenmissbrauchs in den Vordergrund der politischen Debatte gerückt sind.

N2 - Advancing digitalization is changing society and has far-reaching effects on people and companies. Fundamental to these changes are the new technological possibilities for processing data on an ever-increasing scale and for various purposes. The availability of large and high-quality data sets, especially those based on personal data, is crucial. They are used either to improve the productivity, quality, and individuality of products and services or to develop new types of services. Today, user behavior is tracked more actively and comprehensively than ever despite increasing legal requirements for protecting personal data worldwide. That increasingly raises ethical, moral, and social questions, which have moved to the forefront of the political debate, not least due to popular cases of data misuse. Given this discourse and the legal requirements, today's data management must fulfill three conditions: Legality or legal conformity of use and ethical legitimacy. Thirdly, the use of data should add value from a business perspective. Within the framework of these conditions, this cumulative dissertation pursues four research objectives with a focus on gaining a better understanding of (1) the challenges of implementing privacy laws, (2) the factors that influence customers' willingness to share personal data, (3) the role of data protection for digital entrepreneurship, and (4) the interdisciplinary scientific significance, its development, and its interrelationships.

The study assumes that people will only lower their level of consumption if doing so does not also lower personal wellbeing. More precisely, this research investigates how specific subtypes of sustainable anticonsumption (e.g., voluntary simplicity, collaborative consumption, and debt-free living) relate to different states of consumer's wellbeing (e.g., financial, psychosocial, and subjective wellbeing). This work also examines whether consumer empowerment can improve personal wellbeing and strengthen the anticonsumption wellbeing relationship. The results show that voluntarily foregoing consumption does not reduce wellbeing and consumer empowerment plays a significant role in supporting sustainable pathways to consumer wellbeing. This study reasons that empowerment improves consumer sovereignty, but may be detrimental for consumers heavily concerned about debt-free living. The present investigation concludes by proposing implications for public and consumer policymakers wishing to promote appropriate sustainable (anticonsumption) pathways to consumer wellbeing.

The information systems (IS) community has begun to research how information and communications technologies can assist immigrants and refugees, such as by examining how countries can facilitate social-inclusion processes. Migrants face the challenge of joining closed communities that cannot integrate or fear doing so. We conducted a panel discussion at the 2019 Americas Conference on Information Systems (AMCIS) in Cancun, Mexico, to introduce multiple viewpoints on immigration. In particular, the panel discussed how technology can both support and prevent immigrants from succeeding in their quest. We conducted the panel to stimulate a thoughtful and dynamic discussion on best practices and recommendations to enhance the discipline's impact on alleviating the challenges that occur for immigrants in their host countries. In this panel report, we introduce the topic of using ICT to help immigrants integrate and identify differences between North/Central America and Europe. We also discuss how immigrants (particularly refugees) use ICT to connect with others, feel that they belong, and maintain their identity. We also uncover the dark and bright sides of how governments use ICT to deter illegal immigration.

In this paper, we identify factors that influence academics' productivity while working from home during the mandate to self-isolate.

To shed light on the consequences of videoconferencing at work, this study takes a granular look at the implications of the self-view feature for meeting outcomes. Building on self-awareness research and self-regulation theory, we argue that by heightening the state of self-awareness, self-view engagement depletes participants’ mental resources and thereby can undermine online meeting outcomes. Evaluation of our theoretical model on a sample of 179 employees reveals a nuanced picture. Self-view engagement while speaking and while listening is positively associated with self-awareness, which, in turn, is negatively associated with satisfaction with meeting process, perceived productivity, and meeting enjoyment. The criticality of the communication role is put forward: looking at self while listening to other attendees has a negative direct and indirect effect on meeting outcomes; however, looking at self while speaking produces equivocal effects.

Political-economy related aspects are considered in the government's objective function. Lobbying power of firms or fiscal considerations by the government lead to time inconsistency: The government will deviate from a previously announced carbon tax which creates stranded assets. Under rational expectations, we show that a time-consistent policy outcome exists with either a zero carbon tax or a prohibitive carbon tax that leads to zero fossil investments - an "all-or-nothing" policy. Although stranded assets are crucial to such a bipolar outcome, they disappear again under time-consistent policy. Which of the two outcomes (all or nothing) prevails depends on the lobbying power of owners of fixed factors (land and fossil resources) but not on fiscal revenue considerations or on the lobbying power of renewable or fossil energy firms.

We use mandatory firm internships at German universities as an instrument for doing a firm internship while attending university. Employing longitudinal data from graduate surveys, we find positive and significant earnings returns of about 6 percent in both ordinary least squares (OLS) and instrumental variables (IV) regressions. The positive returns are particularly pronounced for individuals and areas of study that are characterized by a weak labor market orientation. The empirical findings show that graduates who completed a firm internship face a lower risk of unemployment during the first year of their careers, suggesting a smoother transition to the labor market.

T1 - The long-run effects of sports club vouchers for primary school children JF - American economic journal: economic policy N2 - Childhood obesity is one of the most serious public health challenges of the twenty-first century. While small-scale experiments change behaviors among adults in the short run, we know little about the effectiveness of large-scale policies or the longer-run impacts. To nudge primary school children into a long-term habit of exercising, the German state of Saxony distributed sports club membership vouchers among all 33,000 third graders in 2009. In 2018, we carried out a register-based survey to evaluate the policy. Even after a decade, awareness of the voucher program was significantly higher in the treatment group.
