However, identifying these factors requires in-depth comprehension of the unique environmental systems, which can only be achieved by detailed water quality monitoring. Within the scope of the joint science and sports event "Elbschwimmstaffel" (swimming relay on the river Elbe) in June/July 2017 organized by the German Ministry of Education and Research, water quality data were acquired along a 550 km long stretch of the Elbe River in Germany. During the survey, eight physiochemical water quality parameters were recorded in high spatial and temporal resolution with the BIOFISH multisensor system. Multivariate statistical methods were applied to identify and delineate processes influencing the water quality. The BIOFISH dataset revealed that phytoplankton activity has a major impact on the water quality of the Elbe River in the summer months. The results suggest that phytoplankton biomass constitutes a substantial proportion of the suspended particles and that photosynthetic activity of phytoplankton is closely related to significant temporal changes in pH and oxygen saturation. An evaluation of the BIOFISH data based on the combination of statistical analysis with weather and discharge data shows that the hydrological and meteorological history of the sampled water body was the main driver of phytoplankton dynamics. This study demonstrates the capacity of longitudinal river surveys with the BIOFISH or similar systems for water quality assessment, the identification of pollution sources and their utilization for online in situ monitoring of rivers.

Die drei zugrundeliegenden Forschungsfragen sind: Wie oft werden Schimpfwörter benutzt? Wie werden diese von den Lesern aufgenommen? Beeinflusst das Thema einer Konversation die Reaktion der Leser und die allgemeine Häufigkeit der Nutzung? Die zugrundeliegenden Daten beinhalten fast 900 Millionen Wörter und stammen aus dem Februar 2017. Sie sind damit höchstaktuell und repräsentativ. Im Vergleich zu anderen Untersuchungen ist das Korpus damit wesentlich größer. Zusätzlich werden im theoretischen Teil die linguistischen Grundlagen zu Schimpfwörtern erörtert. Dazu gehören u.a. Konzepte wie die Höflichkeitstheorie, das Thema Tabu und die dazugehörenden Worte und Zensur. Dies wird getan um die Faktoren, die die Benutzung und Verwendung von Schimpfwörtern beeinflussen darzulegen. Dabei wird herausgestellt, was Schimpfwörter so besonders im Vergleich zu anderen Wortgruppen macht. Zudem werden weitere Forschungsergebnisse, die aus anderen Korpora stammen dargelegt und hinterher mit den Resultaten verglichen. Dies beinhaltet Korpora die sich ebenfalls aus Onlinekommunikationen zusammensetzen, sowie Korpora die gesprochene Sprache wiedergeben. Die Ergebnisse aus allen dargestellten Korpora behandeln Ergebnisse aus der englischen Sprache. Die Ergebnisse dieser Studie weisen daraufhin, dass die Schimpfwörter auf Reddit ungefähr gleichhäufig wie auf anderen Plattformen benutzt werden. Die Reaktionen auf diese Schimpfwörter ist überdurchschnittlich positiv, was darauf schließen lässt, dass die Benutzung von Schimpfwörtern auf Reddit nicht als unhöflich aufgefasst wird. Zudem konnte ein Einfluss des Diskussionsthemas auf die Häufigkeit und Rezeption von Schimpfwörtern festgestellt werden. N2 - The paper deals with the usage of swear words on the online forum "reddit". Three research questions are dealt with: How often are swear words used? How are these swear words received by other users? Does the topic of the conversation have an influence on the reception and amount of usage of swear words? The corpus from which the results are taken comprises almost 900 million words. The words are taken from February 2017. Compared to other, similar studies, the corpus is considerably larger and contempory. In addition, the theoretical part discusses the linguistic basics of swear words. These include concepts such as the theory of politeness, the topic of taboos and its corresponding words and censorship. This is done to explain the factors that influence the use and application of swear words and to explain why swearwords are so special in comparison to other word groups. In addition, further research results from other corpora are presented and compared with the results afterwards. This includes corpora that are also composed of online communication, as well as corpora that reproduce spoken language. The results from all the corpora presented deal with results from the English language. The results of this study indicate that the swear words on "reddit" are used approximately as often as they are on other platforms. The perception of these swear words is mostly positive, which suggests that the use of swear words on "reddit" is not perceived as impolite. In addition, an influence of the discussion topic on the frequency and reception of swear words could be determined.

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.

We con- duct a systematic literature review to examine the existing litera- ture and develop a theoretical framework in order to classify the results. The framework proposes that self-esteem is affected by three distinct processes that incorporate self-evaluative informa- tion: social comparison processes, social feedback processing, and self-reflective processes. Due to particularities of the social networking site environment, the accessibility and quality of self- evaluative information is altered, which leads to online-specific effects on users’ self-esteem. Results of the reviewed studies suggest that when a social networking site is used to compare oneself with others, it mostly results in decreases in users’ self- esteem. On the other hand, receiving positive social feedback from others or using these platforms to reflect on one’s own self is mainly associated with benefits for users’ self-esteem. Nevertheless, inter-individual differences and the specific activ- ities performed by users on these platforms should be considered when predicting individual effects.
