The Home as Productive Place? Investigating Individual Work While Working From Home
Bachelor Thesis from the year 2021 in the subject Computer Science - Commercial Information Technology, grade: 1,3, University of M羹nster (Wirtschaftsinformatik), language: English, abstract: The outbreak of the COVID-19 pandemic has turned the world of knowledge work to the left. Increasing the productivity of knowledge workers is a permanent challenge for organizations. It attracts attention that knowledge workers report being more productive when forced to work from home. This thesis investigates how this perceived increase in productivity might relate to the better conditions for deep individual work knowledge workers encounter in the enforced working from home setting. Therefore, this thesis reviews the enforced working from home literature in the context of deep individual work and conducts two exploratory interviews. This thesis shows narrative evidence that knowledge workers can concentrate better in the workplace at home, prepare their tasks to be suitable for long deep individual work phases, and have the control over their schedule to arrange long interruption-free phases. Thus, knowledge workers engage in deep individual work phases of higher quality, which allows them to be more productive in terms of better work results.

Performance effects of application programming interfaces (API). What is the impact of distinct design choices and value creation strategies?
Seminar paper from the year 2021 in the subject Computer Science - Commercial Information Technology, grade: 1,0, University of G繹ttingen (Wirtschaftswissenschaftliche Fakult瓣t), course: Selected Issues in Digitalization, language: English, abstract: This paper is about Application Programming Interface and methodology and results, contribution and implications and Further research. The rise of digital platforms in recent years induced a substantial emergence of Application Programming Interfaces (APIs) at business organizations. By connecting two parties with mutual interests, APIs facilitate digital collaboration and generate network effects beneficial to both. This literature review examines a research conducted on the performance effects of APIs. It measures the potential impact of distinct design choices and value creation strategies on the commercial outcome and pervasion of an API. The results suggest that API design must be deliberately coordinated with the strategy of value creation in order to achieve desirable business objectives. The findings are demonstrated with a case study on open banking as a practical example. Moreover, the paper is contextualized with two related journal articles, validating and extending the insights found.

Python Brain Teasers
We geeks love puzzles and solving them. The Python programming language is a simple one, but like all other languages it has quirks. This book uses those quirks as teaching opportunities via 30 simple Python programs that challenge your understanding of Python. The teasers will help you avoid mistakes, see gaps in your knowledge, and become better at what you do. Use these teasers to impress your co-workers or just to pass the time in those boring meetings. Teasers are fun! At the beginning of each chapter I'll show you a short Python program and will ask you to guess the output. The possible answers can be: Syntax error Exception Hang Some output (e.g. `[1 2 3]`) Here's how to approach the puzzles. Read through the code. Before moving on to the answer and the explanation, go ahead and guess the output. After guessing the output, run the code and see the output yourself. Finally proceed to read the solution and the explanation. The puzzles are short enough to solve on a coffee break, so carry them with you, have fun, and share them with co-workers. People who make mistakes during the learning process learn better than people who don't. If you use this approach at work when fixing bugs, you'll find you enjoy bug hunting more and become a better developer after each bug you fix. Many of these puzzles are from the author's lessons learned (and others) of shipping bugs to production. He often uses the puzzles as quizzes during conferences and meetups, and they tend to create a buzz of excitement. What You Need: You need to know Python at some level and have experience programming with it. NOTE: The book uses Python version 3.8.2 to run the code; the output _could_ change in future versions. You will need a working Python environment, you can download it from "python.org" https: //www.python.org/downloads/. You will probably want a good IDE for python, two of the most popular ones are "Visual Studio Code" https: //code.visualstudio.com/ and "PyCharm" https: //www.jetbrains.com/pycharm/.

Die M繹glichkeiten Texte durch Text Mining zu analysieren, um Fake News zu erkennen, werden dargestellt. Daher steht im Fokus der Bachelorarbeit besonders die Methode der stilbasierten Fake News Erkennung, da durch das Text Mining einige Verfahren dieser Methodik angewendet werden k繹nnen. Um Ergebnisse bez羹glich der Erkennung von Fake News, anhand von stilbasierten Methoden des Text Minings zu erhalten, wird ein ausgew瓣hlter und aufbereiteter Datensatz aus politischen wahren und falschen Nachrichten aus dem Jahr 2016 und 2017 separat f羹r Nachrichtentitel und Nachrichtentexte analysiert. Durch die sehr hohen erreichten Genauigkeiten zwischen 92 und 97 Prozent bei den durchgef羹hrten Klassifikationen durch TF-IDF Vektorisierung und Anwendung des Naive Bayes Klassifikators sowie der logistischen Regression, kann best瓣tigt werden, dass sich das Text Mining zur Erkennung von Fake News eignet und klassische Fake News durch Text Mining erkannt werden. Allerdings beschr瓣nkt sich die Erkennung von Fake News anhand von Text Mining auf einen sorgf瓣ltig ausgew瓣hlten sowie aufbereiten Datensatz mit bereits enthaltenen und gekennzeichneten Fake und True News. Die erkannten Muster und Ergebnisse sind lediglich f羹r vergleichbare Nachrichten bez羹glich der Thematik, Sprache und Zeitraum verwendbar und nicht verallgemeinerbar. Zudem wurde anhand der durchgef羹hrten Text Mining Methoden wie EDA und Clustering eine Sprache der gef瓣lschten Nachrichten identifiziert und dargestellt. Diese Sprache weist auf, dass im Datensatz die Worte hillari und clinton die am meisten vorkommenden und eindeutigsten Fake News W繹rter
