One of the most frequently used ways for information dissemination today is through social media, and when it comes to real-time information, Twitter is often the channel of choice. Thus, this paper discusses how Big Data Analytics (BDA) can take advantage of information streaming from Twitter to generate alerts and provide information in real-time on ongoing disasters. The paper proposes TAGS (Twitter Alert Generation System), a novel solution for collecting and analyzing social media streaming data in realtime and subsequently issue warnings related to ongoing disasters using a combination of Hadoop and Spark frameworks. The paper tests and evaluates the proposed solution using Twitter data from the 2018 earthquake in Palu City, Sulawesi, Indonesia. The proposed architecture was able to issue alert messages on various disaster scenarios and identify critical information that can be utilized for further analysis. Moreover, the performance of the proposed solution is assessed with respect to processing time and throughput that shows reliable system efficiency.

Evidence from national digitalisation strategies JF - dms – der moderne staat – Zeitschrift für Public Policy, Recht und Management N2 - This paper seeks to better understand the paradigm shift towards ‘networked governance’ in digitalisation discourse. Little is known about the link between digitalisation reforms and the main reform paradigms in public management studies. By analysing French and German national digitalisation strategies over time, we find that neo-Weberian, new public management, and networked governance discourses co-exist within the digital era, although networked governance rhetoric is increasingly influential. However, a closer examination reveals that this shift in discourse is unrelated to the increased integration of nonstate actors in actual decision-making and service delivery.

A machine-learning approach to termination traits of public corporations in English and German local governments JF - Public Management Review N2 - Corporatization has gained scholarly attention in recent years, yet little is known regarding why many corporations are eventually terminated, and what happens to their form and functions thereafter. Reinternalizing services is one option local governments may pursue. This paper focuses on the impact of tensions (systemic contradictions) on this final resolution reached: Do local governments choose or refuse reinternalization? Conducting machine learning, I predict termination outcomes based on an original dataset of 244 ceased English and German companies (2010–2020). The results show that macrosystemic tensions are more relevant for resourcing decisions and reinternalization is less likely to be caused by formal ownership issues.

While much of the literature acknowledges that the fundamental restructuring coupled with technical capacity that these joint projects require leads to increased complexity, little is known about how different types of complexity interact within the collaborative process. Using established concepts of substantive, strategic, and institutional complexity, we apply complexity theory in collaborative digital environments. To do so, eight digital projects are analysed that differ by state structure and government level. Using a cross-case design with 50 semi-structured expert interviews, we find that each digitalisation project exhibits all types of complexity and that these complexities overlap. However, clear differences emerge between national and local level projects, suggesting that complexity in digitalisation processes presents different challenges for collaborative digitalisation projects across contexts.

However, claims by policy-makers and political activists regarding the effectiveness and likely consequences of legal regulations remain largely untested. We rely on qualitative interviews and two expert surveys to examine the behavior of public relations professionals in response to online hatespeech when having the option of using the new user-complaint mechanism under the German Network Enforcement Act (NetzDG). Our findings reveal that strategies depend on whether professionals work at public sector institutions, business, or civil society organizations and political parties. Public sector institutions are likely to report to the platform, but not under NetzDG. Civil society organizations are likely to choose content moderation, counterspeech, and other forms of intervention. Businesses deploy a wide range of strategies. In practice, Germany's procedural approach relying on user-complaint mechanisms to deal with online hatespeech is not used by experts as a means to combat online harassment.

JF - Amicus Curiae N2 - The European Union (EU) has been leading the world with its influential digital regulation. However, the EU’s legislative process is sufficiently complex and careful that some national legislation clearly influenced by the EU’s AI Regulation is already in place in other countries, before the law has even been finalized in the EU. Meanwhile, other states and regions are just beginning to develop AI policy. For both the EU and such others, we here describe the outcomes of the first round of legislative action by one of the EU’s two legislative bodies, the European Parliament, in terms of modifying the Artificial Intelligence Act. The Parliament has introduced a number of changes we consider to be enormously important, some in a very good way, and some in a very bad way. At stake is whether the AI Act really brings the power and strength of product law to continuously scale improved practice on products in the EU with intelligent components, or whether the law becomes window-dressing aimed only at attacking a few elite actors post hoc. We describe here the EU process, the changes and our recommendations.

To address online harms and rising platform power the DSA clarifies responsibilities of platforms and outlines a new technology regulatory framework to increase oversight. One key oversight instrument constitutes Article 40 of the DSA, which lays out data access for vetted researchers, who add value to regulators and the broader public as creators of knowledge, educators, advisors, innovators, and watchdogs. Currently, the EU Commission and national governments make important decisions regarding Digital Service Coordinators (DSCs) that play a key role in implementation. Based on expertise on European public administration and political science we lay out key challenges and success factors of DSCs that will play a role in promoting successful cooperation between DSCs and researchers. We provide three recommendations: First, we recommend to strengthen transfer of scientific knowledge into policy-making by processing publicly accessible publications within public administrative bodies. To this end, capacities of DSCs need to be increased. In addition, we also point towards the database of vetted researchers collected by the Board of DSCs as important resource in order to strengthen knowledge transfer. Second, the DSC network requires agile institutions with fast response time in order to enable researchers to play a constructive role in implementation. This also includes institutional procedures between DSCs and the Intermediary Body and Data Protection Agencies. To avoid delay in implementation agile institution-building needs to start now. Finally, institutional safeguards will help to avoid strategic choice of companies of the DSC of establishment. At the same time, the Irish DSC's capacity should be strengthened compared to other national DSCs since most large intermediary services providers have their European headquarters in Ireland.

Collaborative public administration in the context of national digitalization strategies JF - Governance N2 - Despite claims of a paradigmatic shift toward the increased role of networks and partnerships as a form of governance—driven and enabled by digital technologies—the relation of “Networked Governance” with the pre-existing paradigms of “Traditional Weberian Public Administration” and “New Public Management” remains relatively unexplored. This research aims at collecting systematic evidence on the dominant paradigms in digitalization reforms in Europe by comparing the doctrines employed in the initial and most recent digitalization strategies across eight European countries: Estonia, France, Germany, Italy, The Netherlands, Norway, Spain, and the United Kingdom. We challenge the claim that Networked Governance is emerging as the dominant paradigm in the context of the digitalization of the public sector. The findings confirm earlier studies indicating that information and communication technologies tend to reinforce some traditional features of administration and the recentralization of power. Furthermore, we find evidence of the continued importance of key features of “New Public Management” in the digital era.

However, despite the significance of corporatization in public administration and the controversy over its viability as a strategy for enhancing public service provision, there is limited empirical research on its trajectory and associated effects. This dissertation fills this important gap in the literature by examining the causes, dynamics, and consequences of corporatization. It challenges the claim that we are witnessing a resurgence of the state in recent years, resulting in a pendulum shift from the private to the public sector. A mixed-methods approach is employed to analyze three original datasets from English and German local government contexts. Theoretical perspectives rooted in rational choice are complemented by those accounting for irrational ambiguity to capture the unique ambidexterity of corporatization. After clarifying the theoretical background in Chapter 1, this exploration unfolds across three empirical chapters. Chapter 2 investigates what drives corporatization. It reveals that ownership structures in corporatization have become increasingly complex and political–rather than economic–incentives may explain shifts toward indirect municipal ownership. Chapter 3 examines what causes corporatization to reverse. It shows that a return of services to the core local government after a company closes is less likely than other forms of service provision, while the type of service is the factor that matters most for termination decisions. Chapter 4 analyzes how local governments experience and cope with reverse corporatization. Local governments and their employees evidently and mutually impact the return process, which can induce private sector-informed change within the bureaucracy, albeit with limited transformative power. Ultimately, this dissertation finds no clear evidence of a pendulum shift toward the local public sector. This conclusion follows from conceptual and empirical differentiation and depends on how corporatization is framed, as well as on the specific country, service type, and dimension of public influence considered. It also suggests that the notion of the pendulum shift needs reevaluation. For practitioners, this holds several implications that encourage optimism about reform, and advise against an arbitrary approach to diversifying costs.

JF - Media and Communication N2 - Social media campaigning is increasingly linked with anti-democratic outcomes, with concerns to date centring on paid adverts, rather than organic content produced by a new set of online political influencers. This study systematically compares voter exposure to these new campaign actors with candidate-sponsored ads, as well as established and alternative news sources during the US 2020 presidential election. Specifically, we examine how far higher exposure to these sources is linked with key trends identified in the democratic deconsolidation thesis. We use data from a national YouGov survey designed to measure digital campaign exposure to test our hypotheses. Findings show that while higher exposure to online political influencers is linked to more extremist opinions, followers are not disengaging from conventional politics. Exposure to paid political ads, however, is confirmed as a potential source of growing distrust in political institutions.
