Recent spikes in social networking site (SNS) usage times have launched investigations into reasons for excessive SNS usage. 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.
The devil in disguise
(2021)
Envy constitutes a serious issue on Social Networking Sites (SNSs), as this painful emotion can severely diminish individuals' well-being. With prior research mainly focusing on the affective consequences of envy in the SNS context, its behavioral consequences remain puzzling. While negative interactions among SNS users are an alarming issue, it remains unclear to which extent the harmful emotion of malicious envy contributes to these toxic dynamics. This study constitutes a first step in understanding malicious envy’s causal impact on negative interactions within the SNS sphere. Within an online experiment, we experimentally induce malicious envy and measure its immediate impact on users’ negative behavior towards other users. Our findings show that malicious envy seems to be an essential factor fueling negativity among SNS users and further illustrate that this effect is especially pronounced when users are provided an objective factor to mask their envy and justify their norm-violating negative behavior.
The envy spiral
(2020)
On Social Networking Sites (SNS) users disclose mostly positive and often self-enhancing information. Scholars refer to this phenomenon as the positivity bias in SNS communication (PBSC). However, while theoretical explanations for this phenomenon have been proposed, an empirical proof of these theorized mechanisms is still missing. The project presented in this Research-in-Progress paper aims at explaining the PBSC with the mechanism specified in the self-enhancement envy spiral. Specifically, we hypothesize that feelings of envy drive people to post positive and self-enhancing content on SNS. To test this hypothesis, we developed an experimental design allowing to examine the causal effect of envy on the positivity of users’ subsequently posted content. In a preliminary study, we tested our manipulation of envy and could show its effectiveness in inducing different levels of envy between our groups. Our project will help to broaden the understanding of the complex dynamics of SNS and the potentially adverse driving forces underlying them.
Werner Krause and Christina Gahn argue that we need to pay more attention to how the media communicates the results of opinion polls to the public. Reporting methodological details, such as margins of error, can alter citizens’ vote choices on election day. This has important implications for elections around the world
Conclusion
(2023)
Based on the previous findings in this book, Chapter 18 by Heike Krieger and Andrea Liese discusses the general dynamics of change or metamorphosis in the international legal order. They discern a mixed picture of an international order between metamorphosis—that is, a more fundamental transformation—of international law, norm change, turbulences, and robustness. They explain drivers of change and highlight factors such as national interests during the war on terror, changing long-term foreign policy beliefs, and the rise in populism and autocracy, before discussing the most common strategies the actors involved use. Other relevant factors include changes in the political environment, such as shocks and power shifts or the ambiguous role of fragmentation. Moreover, they identify factors that make legal norms robust, including the vital role of norm defenders and legal and institutional structures as stabilizing elements. Krieger and Liese conclude by cautioning that if the attacks on the international order continue at the current frequency and magnitude, a metamorphosis of international law will likely be unstoppable.
Does personality matter? Is an individual who is open to experience more or less likely to become an entrepreneur? Is it better to score low or high in agreeableness for surviving as an entrepreneur? To the extent that personality captures one part of entrepreneurial abilities, which are usually unobservable, the analysis of traits and personality characteristics helps better understanding such abilities. This chapter reviews research on the relationship between personality and entrepreneurship since 2000 and shows that possessing certain personality characteristics will make it more likely that an individual will start an own business and hire staff. More specifically, with respect to the entry decision, research finds that nearly all so-called Big Five factors as well as several specific personality characteristics influence the entry probability into entrepreneurship. Further, entrepreneurs are more likely to hire, the higher they score in risk tolerance, trust, openness to experience, and conscientiousness. However, different factors such as low scores in agreeableness, the only Big Factor that does not affect entrepreneurial entry, influence entrepreneurial survival. And for some of characteristics that influence entrepreneurial entry, like high scores in the factor openness for experience or in risk tolerance, “revolving door effects” are found, explaining why some entrepreneurs subsequently exit again the market.
This chapter analyses managerial reforms at the subnational level of government from a comparative perspective and outlines possible routes for future comparative research. It examines reforms of the external relationships between local governments and private service providers, which were aimed at transforming the organizational macro-setting of local service provision, the task portfolio and functional profile of local governments. The chapter then moves to scrutinizing internal managerial reforms concerned with the modernization of organization and processes and the improvement of management capacities inside local administrations meant to strengthen performance, output- and consumer-orientation in local service delivery. The country sample includes the United Kingdom (England), Sweden, and Germany that represent three distinct types of administrative culture and local government in Europe.
This book compares local self-government in Europe. It examines local institutional structures, autonomy, and capacities in six selected countries - France, Italy, Sweden, Hungary, Poland, and the United Kingdom - each of which represents a typical model of European local government. Within Europe, an overall trend towards more local government capacities and autonomy can be identified, but there are also some counter tendencies to this trend and major differences regarding local politico-administrative settings, functional responsibilities, and resources. The book demonstrates that a certain degree of local financial autonomy and fiscal discretion is necessary for effective service provision. Furthermore, a robust local organization, viable territorial structures, a professional public service, strong local leadership, and well-functioning tools of democratic participation are key aspects for local governments to effectively fulfill their tasks and ensure political accountability. The book will appeal to students and scholars of Public Administration and Public Management, as well as practitioners and policy-makers at different levels of government, in public enterprises, and in NGOs.
Comparative methods B
(2020)
This chapter outlines the relevance and value of comparative approaches and methods in studying Public Administration (PA). It discusses the roots and current developments of comparative research in PA and discusses various methodological venues for cross-country comparisons, such as most similar/dissimilar systems designs, the method of concomitant variation and the difference-in-difference method. Besides the description of these approaches, we highlight their conceptual value for theory-driven empirical comparative research. Drawing on selected pieces of comparative research, the chapter furthermore provides examples for the application of comparative methods in practice presenting empirical findings and highlighting strengths and weaknesses. The chapter finally emphasizes that the methodological development in comparative PA research has by far not yet reached its end, and that some future challenges need to be addressed, such as the issues of causality, generalizability, and mixed-methods approaches.
This chapter addresses the role of evaluation of and in public administration. We focus on two analytical key dimensions: a) the provider of the evaluation and b) the subject of the evaluation. Four major types of evaluation are distinguished: (1) external institutional evaluation, (2) internal institutional evaluation, (3) external evaluation of administrative action/results, (4) internal evaluation of administrative action/results. Type 1 and 2 refer to evaluation of administrative structures and processes as the subject of administrative reform. Type 3 and 4 represent different versions of evaluation in public administration, because the subject is administrative action and its outputs. The chapter highlights salient approaches and organizational settings of evaluation and provides insights into the institutionalization of an evaluation function in public administration. Finally, the chapter draws lessons regarding strengths and potentials but also remaining weaknesses and challenges of evaluation of and in public administration.
Data sharing requires researchers to publish their (primary) data and any supporting research materials. With increased attention on reproducibility and more transparent research requiring sharing of data, the issues surrounding data sharing are moving beyond whether data sharing is beneficial, to what kind of research data should be shared and how. However, despite its benefits, data sharing still is not common practice in Information Systems (IS) research. The panel seeks to discuss the controversies related to data sharing in research, specifically focusing on the IS discipline. It remains unclear how the positive effects of data sharing that are often framed as extending beyond the individual researcher (e.g., openness for innovation) can be utilized while reducing the downsides often associated with negative consequences for the individual researcher (e.g., losing a competitive advantage). To foster data sharing practices in IS, the panel will address this dilemma by drawing on the panelists’ expertise.
Visual Social Networking Sites (SNSs) enable users to present themselves favorably to gain likes and the attention of others. Especially, Instagram is known for its focus on beauty, fitness, fashion, and dietary topics. Although a large body of research reports negative weight-related outcomes of SNS usage (e.g., body dissatisfaction, body image concerns), studies examining how SNS usage relates to these outcomes are scarce. Based on the visual normalization theory, we argue that SNS content facilitates normalization of so-called thin- and fit-ideals, thereby leading to biased perceptions of the average body weight in society. Therefore, this study tests whether Instagram use is associated with perceiving that the average person weighs less. Responses of 181 survey participants confirm that Instagram use is negatively related to average weight perception of both women and men. These findings contribute to the growing body of research on how SNS use relates to negative weight-related outcomes.

Shape-memory polymers

In the last two centuries BC, with the Republic limping towards its end, the cultivated ruling elite began to lose its moral and political authority.1 Its members not only held themselves responsible for the so-called crisis of tradition, but at the same time also conveyed the impression of a loss of memory, as if all Romans were suffering from some kind of amnesia or identity crisis.2 In particular, institutional figures such as pontiffs and augurs, who had preserved Rome’s memory throughout its history, were accused of neglecting their duties and, by extension, of allowing ancient practices and values to slowly disappear.3 Accordingly, Cicero and Varro, both perfect representatives of this elite, employed recurrent terms such as neglect (neglegentia/neglegere), involuntary abandon (amittere), oblivion (oblivio), vanishing of institutions (evanescere), and ignorance (ignoratio/ignorare) to describe this critical loss of information; they depicted the citizenry of Rome (civitas) as disoriented and estranged, incapable of sharing any common knowledge or values.
Article 1 E 1951 Convention
(2024)
This chapter elaborates on the function of Article 1 E of the 1951 Convention, which was originally aimed at German refugees. It refers to a special group of people who qualify for refugee status but enjoy the rights of national citizens despite their lack of formal citizenship. The article's object and purpose revolve around excluding persons from refugee protection who do not need any international protection since they have the status of national citizens. Additionally, access to refugee status is excluded ipso facto because the individual may resort to effective protection similar to that of citizenship upon being admitted to the country of sojourn. The chapter explains how Article 1 E is an integral part of the balanced system of international refugee protection prescribed by the Convention.
Reputation and influence
(2022)
International public administrations (IPAs) are collective bodies within international organizations (IOs) made up of international civil servants that support the intergovernmental bodies and member states. Over the last decade, research on these bodies has “gained substantial momentum”. Comparative assessments of IPAs reputation among stakeholders are rare. The literature on the sociological legitimacy of IOs is most advanced in this respect. A comparative agenda on IPAs reputation for expertise or neutrality is still in its infancy. Research has shown that different stakeholders view the same IPA quite differently. Reputation is a crucial concept in political science and IR research and has been widely used to predict states’ future behavior, notably regarding cooperation and conflict. IPAs seem to vary substantially in their reputation for expertise among critical interlocutors. In financial policy, several prominent IPAs are seen as experts, including the European Central Bank and the IMF.
Social media constitute an important arena for public debates and steady interchange of issues relevant to society. To boost their reputation, commercial organizations also engage in political, social, or environmental debates on social media. To engage in this type of digital activism, organizations increasingly utilize the social media profiles of executive employees and other brand ambassadors. However, the relationship between brand ambassadors’ digital activism and corporate reputation is only vaguely understood. The results of a qualitative inquiry suggest that digital activism via brand ambassadors can be risky (e.g., creating additional surface for firestorms, financial loss) and rewarding (e.g., emitting authenticity, employing ‘megaphones’ for industry change) at the same time. The paper informs both scholarship and practitioners about strategic trade-offs that need to be considered when employing brand ambassadors for digital activism.
Article 34 1951 Convention
(2024)
This chapter tackles the features and historical development of the 1951 Convention's Article 34. It explains the function of the provision, which primarily focuses on requesting Contracting States to facilitate the assimilation and naturalization of refugees. Moreover, the provision forms the legal bases for local integration and naturalization as some of the traditional durable solutions to refugeehood. The soft obligation imposed by Article 34 primarily focuses on the long-term solution by naturalization. The chapter then elaborates on the balance between local integration, naturalization, and voluntary return after it was disrupted due to the fall of the Iron Curtain in 1989.
Labor unions’ greatest potential for political influence likely arises from their direct connection to millions of individuals at the workplace. There, they may change the ideological positions of both unionizing workers and their non-unionizing management. In this paper, we analyze the workplace-level impact of unionization on workers’ and managers’ political campaign contributions over the 1980-2016 period in the United States. To do so, we link establishment-level union election data with transaction-level campaign contributions to federal and local candidates. In a difference-in-differences design that we validate with regression discontinuity tests and a novel instrumental variables approach, we find that unionization leads to a leftward shift of campaign contributions. Unionization increases the support for Democrats relative to Republicans not only among workers but also among managers, which speaks against an increase in political cleavages between the two groups. We provide evidence that our results are not driven by compositional changes of the workforce and are weaker in states with Right-to-Work laws where unions can invest fewer resources in political activities.
Breaking down barriers
(2024)
Many researchers hesitate to provide full access to their datasets due to a lack of knowledge about research data management (RDM) tools and perceived fears, such as losing the value of one's own data. Existing tools and approaches often do not take into account these fears and missing knowledge. In this study, we examined how conversational agents (CAs) can provide a natural way of guidance through RDM processes and nudge researchers towards more data sharing. This work offers an online experiment in which researchers interacted with a CA on a self-developed RDM platform and a survey on participants’ data sharing behavior. Our findings indicate that the presence of a guiding and enlightening CA on an RDM platform has a constructive influence on both the intention to share data and the actual behavior of data sharing. Notably, individual factors do not appear to impede or hinder this effect.
It’s personal
(2021)
The new technologies of the Fourth Industrial Revolution (4IR) are disrupting traditional models of work and learning. While the impact of digitalization on education was already a point of serious deliberation, the COVID-19 pandemic has expedited ongoing transitions. With 90% of the world’s student population having been impacted by national lockdowns—online learning has gone from being a luxury to a necessity, in a context where around 3.6 billion people are offline. As the impacts of the 4IR unfold alongside the current crisis, it is not enough for future policy pathways to prioritize educational attainment in the traditional sense; it is essential to reimagine education itself as well as its delivery entirely. Future policy narratives will need to evaluate the very process of learning and identify the ways in which technology can help reduce existing disparities and enhance digital access, literacy and fluency in a scalable manner. In this context, this chapter analyses the status quo of online learning in India and Germany. Drawing on the experiences of these two economies with distinct trajectories of digitalization, the chapter explores how new technologies intersect with traditional education and local sociocultural conditions. Further, the limitations and opportunities presented by dominant ed-tech models is critically analyzed against the ongoing COVID-19 pandemic.
The dynamic 1H NMR study of some primary carbamates in the solvents CDCl3 and CD3COCD3 between 183 and 298 K is reported. The free energies of activation, thus obtained (12.4 to 14.3 kcal mol-1), were attributed to the conformational isomerization about the N-C bond. These barriers to rotation show solvent dependence in contrast to the tertiary analogues and are lower in free energy by ca. 2-3 kcal mol-1.

The EU and its member countries have been laggards in using forest carbon to reduce EU emissions. The European Green Deal aims to change this. As part of its long-term emissions reductions, the EU aims to offset this by creating land-based carbon sinks, especially forest carbon sinks as well as carbon capture and storage. This chapter focuses on the role of forest carbon as part of the EU's climate policies towards achieving net-zero greenhouse gas emissions by 2050. It furthermore examines the European Commission's proposed forest strategy and its proposal for a revised LULUCF Regulation. The chapter shows that the logic of appropriateness dominates the European Commission's forest policies. Finally, the chapter makes policy recommendations on how the EU could credibly use long-term carbon sinks to achieve climate neutrality.
