Individual and shared digital repertoires – older adults managing digital services
2021
The rise of public and other non-recreational digital services is based on the idea of catering to the daily needs of the citizens cost-efficiently and with ease. Previous research has approached t...
Reader Comments Agentive Power in COVID-19 Digital News Articles: Challenging Parascientific Information?
2022
The recent COVID-19 pandemic has triggered an enormous stream of information. Parascientific digital communication has pursued different avenues, from mainstream media news to social networking, at times combined. Likewise, citizens have developed new discourse practices, with readers as active participants who claim authority. Based on a corpus of 500 reader comments from The Guardian, we analyse how readers build their authorial voice on COVID-19 news as well as their agentive power and its implications. Methodologically, we draw upon stance markers, depersonalisation strategies, and heteroglossic markers, from the perspective of discursive interpersonality. Our findings unearth that stan…

Seek and you shall find? A content analysis on the diversity of five search engines’ results on political queries
2020
Search engines are important political news sources and should thus provide users with diverse political information ��� an important precondition of a well-informed citizenry. The search engines��� algorithmic content selection strongly influences the diversity of the content received by the users ��� particularly since most users highly trust search engines and often click on only the first result. A widespread concern is that users are not informed diversely by search engines, but how far this concern applies has hardly been investigated. Our study is the first to investigate content diversity provided by five search engines on ten current political issues in Germany. The findings show t…
Communication and PR from a Cross-Cultural Standpoint
2012
How should we approach cultural diversity in the workplace? Multinational corporations, transnational project teams and glocalised production and distribution processes raise challenging cultural issues for communication and PR professionals. Yet the complex nature of the communication processes involved means that existing models of cross-cultural or intercultural communication often seem inadequate to allow researchers or professionals get to grips with the complexity of the interactions encountered. This book aims to pinpoint and address the apparent limits of many traditional intercultural communi-cation research methods, when they are applied to real situations in the hybrid and cosmop…

On the inductive inference of recursive real-valued functions
1999
AbstractWe combine traditional studies of inductive inference and classical continuous mathematics to produce a study of learning real-valued functions. We consider two possible ways to model the learning by example of functions with domain and range the real numbers. The first approach considers functions as represented by computable analytic functions. The second considers arbitrary computable functions of recursive real numbers. In each case we find natural examples of learnable classes of functions and unlearnable classes of functions.

Linear-size suffix tries
2016
Suffix trees are highly regarded data structures for text indexing and string algorithms [MCreight 76, Weiner 73]. For any given string w of length n = | w | , a suffix tree for w takes O ( n ) nodes and links. It is often presented as a compacted version of a suffix trie for w, where the latter is the trie (or digital search tree) built on the suffixes of w. Here the compaction process replaces each maximal chain of unary nodes with a single arc. For this, the suffix tree requires that the labels of its arcs are substrings encoded as pointers to w (or equivalent information). On the contrary, the arcs of the suffix trie are labeled by single symbols but there can be Θ ( n 2 ) nodes and lin…
Improving computation efficiency using input and architecture features for a virtual screening application
2023
Virtual screening is an early stage of the drug discovery process that selects the most promising candidates. In the urgent computing scenario it is critical to find a solution in a short time frame. In this paper, we focus on a real-world virtual screening application to evaluate out-of-kernel optimizations, that consider input and architecture features to improve the computation efficiency on GPU. Experiment results on a modern supercomputer node show that we can almost double the performance. Moreover, we implemented the optimization using SYCL and it provides a consistent benefit with the CUDA optimization. A virtual screening campaign can use this gain in performance to increase the nu…
