In [1] haben wir eine New School of IT beschrieben, die erste Antworten auf die Herausforderungen an IT-Organisationen bietet. Zehn Jahre nach der ersten Formulierung des Begriffes sind durch Cloud Native Computing oder künstliche Intelligenz bereits konkrete Meilensteine in der New School of IT erreicht, es bleiben aber auch eine Reihe von offenen Herausforderungen an Methodenkompetenz und Ausbildung. Wir fassen im Folgenden den Stand der Dinge zusammen.

While relevant studies have documented Internet censorship in non-European countries, as well as the use of such infrastructures for political reasons, this study examines network interference practices such as website blocking against the backdrop of an almost complete lack of EU-related research. Specifically, it performs and demonstrates an analysis for the total of 27 EU countries based on three different sources. They include first, tens of millions of historical network measurements collected in 2020 by Open Observatory of Network Interference volunteers from around the world; second, the publicly available blocking lists used by EU member states; and third, the reports issued by network regulators in each country from May 2020 to April 2021. Our results show that authorities issue multiple types of blocklists. Internet Service Providers limit access to different types and categories of websites and services. Such resources are sometimes blocked for unknown reasons and not included in any of the publicly available blocklists. The study concludes with the hurdles related to network measurements and the nontransparency from regulators regarding specifying website addresses in blocking activities.

Moreover, due to the constant evolution in the field, previous studies are far from reflecting the current situation. The goal of this article is to evaluate and compare current solutions using two experimental studies. In the first part of the study, based on tweets about airline service quality, we test the solutions of six vendors with different market power, such as Amazon, Google, IBM, Microsoft, Lexalytics, and MeaningCloud, and report their measures of accuracy, precision, recall, (macro)F1, time performance, and service level agreements (SLA). Furthermore, we compare two of the services in depth with multiple data sets and over time. The services tested here are Google Cloud Natural Language API and MeaningCloud Sentiment Analysis API. For evaluating the results over time, we use the same data set as in November 2020. In addition, further topic-specific and general Twitter data sets are used. The experiments show that the IBM Watson NLU and Google Cloud Natural Language API solutions may be preferred when negative text detection is the primary concern. When tested in July 2022, the Google Cloud Natural Language API was still the clear winner compared to the MeaningCloud Sentiment Analysis API, but only on the airline service quality data set; on the other data sets, both services provided specific benefits and drawbacks. Furthermore, we detected changes in the sentiment classification over time with both services. Our results motivate that an independent, critical, and longitudinal experimental analysis of sentiment analysis services can provide interesting insights into their overall reliability and particular classification accuracy beyond marketing claims to critically compare solutions based on real data and analyze potential weaknesses and margins of error before making an investment.

A. T1 - New insights into the ‘Indonesian way’ of managing international business negotiations JF - SN Business & Economics N2 - Indonesia has enjoyed impressive economic growth since the early 2000s and consequently attracted significant business interest from western companies. Yet, the Indonesian business context has also been notoriously impacted by corruption, which presents a serious challenge for international business negotiations. Interestingly, in scholarly research little is known about the indigenous management practices within the Indonesian context. This study therefore investigates indigenous management practices during international business negotiations taking place in the emerging market of Indonesia, that may determine the success or failure of multinational corporations’ negotiations. We conduct an inductive analysis of rich and context-specific data generated through 55 in-depth interviews of Indonesian and non-Indonesian managers. We discover: (1) the importance of perantara as a third-party agent, specific to Indonesia, that operates as a backchannel conduit for communication between parties and is essential for progressing to the face-to-face negotiation stage; and (2) the unique relationship-building process essential for business negotiations in Indonesia, which moves from task orientation to relationship-building orientation. To the best of our knowledge, our study is one of the first to tackle such specific indigenous management behaviours during international business negotiation in Indonesia from a context-specific insider’s perspective. This study provides useful insights for managers of foreign multinational corporations on how to manage certain indigenous Indonesian management behaviours if they are to achieve successful investment outcomes.

The complicated implementation of international law into national schools JF - Journal of Education Policy N2 - This paper starts with the increasing discussions on juridification in education. Concerning theorizing on such processes, we examine the poor implementation of the UN Convention on the Rights of Persons with Disabilities Convention on the Rights of Persons with Disabilities, CRPD (2008) in the school sector of Germany. The paper considers the reasons for this failed endeavor by analyzing the complex, multilevel relations between policy and law in different national and historical contexts. With this, aspects of juridification as a process in education policy can be illuminated. In this regard, we suggest crucial aspects regarding juridification in public education: a focus on regulative failures in juridification processes, juridification’s contexts, the mandate for putting it into action, the allocation of resources, and finally, its objective and subjective rights dimensions, i.e. how an individual can claim rights within the machinery of public education.

School administration is an under-illuminated aspect of curriculum research. The paper commences from the notion that, in mass education, a school system is operationalized by many schools, which are coupled to each other and to political decisions. Here is the curriculum vital. Building on the classic work of Stefan Hopmann, a curriculum is part of the administrational structure of the school system. The Article suggests several categories that can describe the nature and function of school administration in various contexts. There are external matters of schooling, such as school buildings, school food, etc. and internal matters of schooling, such as curriculum, pedagogy, and evaluation. Individual schools and school administration are coupled via licences, and programmatic, professional, and procedural supervision. The article employs these categories with a comparison of a decentralized Sweden and a centralized Germany. The comparison investigated 290 Swedish municipality school administrations and 45 state education authorities in 4 German federal states. In this comparison many interesting similarities between both contexts can be hightligthed.

Universities play a pivotal role in this process through the creation and dissemination of knowledge, engaging broad sectors of society to improve understanding and to inspire action. However, universities face barriers in fulfilling their role in addressing complex societal challenges such as climate change. This contribution explores the potential of the arts to foster public engagement and stimulate responsible pathways of research at universities within this context. Using an integrative literature review, the paper provides an overview of conceptual contributions aimed at understanding different modes of the interplay between the arts, science, and society, or, more specifically, of integrating the arts into the university’s third mission. The overview is organized around three pillars: (i) arts in knowledge creation, (ii) arts in the communication of scientific research, and (iii) arts in the alignment of research with societal needs. Within each pillar, specific modes of interplay between the arts, science, and society are identified and exemplified with selected climate-related artworks: i) artistic research, arts-based research, arts-science collaboration, ii) arts-based science communication and iii) arts-based responsible research and innovation. The examples hihlight resources, processes and activities enabling different modes of interplay between arts, science and society. The value of defining such modes of interplay is their use as conceptual tools for deriving arts-based strategies for university’s third mission. They can help understanding the integrative potential of arts in third mission activities around diverse pillars and relevant conditions for impact assessment.
