TY - BOOK A1 - Brasche, Ulrich T1 - Auf dem Weg zu mehr Klimagerechtigkeit Im Bündnis mit dem Globalen Süden Widerstände überwinden N2 - Die Menschen sind im Anthropozän auf einer gefährlichen Reise. Das Ziel steht noch nicht fest. Die Ankunft in einem guten Leben für alle innerhalb planetarer Grenzen ist immer noch möglich. Aber zurzeit führt die Reise eher zu einer Überhitzung der Erde. Gesundheit und Leben wären dann für viele Lebewesen – auch für den Menschen – massiv gefährdet. Das Buch behandelt die Fragen: • Wie sind wir in diese Lage geraten? • In welcher Richtung können Auswege liegen? • Welche Hindernisse sind zu überwinden? Es werden Strategien abgewogen und einige überraschende Bündnispartner identifiziert. Geschickt gestaltete Märkte können helfen, die Erderwärmung aufzuhalten. Nur in einer gleicheren und gerechteren Welt könnten alle Menschen gut, aber bescheidener leben. Die Alternative dazu wäre eine übererhitzte, gefährliche Welt. Eine gute Entwicklung ist noch möglich. Sie erfordert eine globale Transformation von Wirtschaft und Gesellschaft. Die wohlhabenden Staaten sind gut beraten, die Interessen des „Globalen Südens“ und der künftigen Generationen zu respektieren – auch durch den klugen Einsatz erheblicher Finanzmittel und eine Kooperation auf Augenhöhe.

Preliminary Study Results T2 - Kumar, V., Kyriakopoulos, G.L., Akberdina, V., Kuzmin, E. (eds) Digital Transformation in Industry . DTI 2022. Lecture Notes in Information Systems and Organisation, vol 61. Springer, Cham N2 - The fast-paced digitalization and automation make hard skills acquired by employees in their academic study programs outdated and irrelevant very fast. Hence, researchers and practitioners have recently demonstrated a growing interest in studying soft skills in various settings, including leadership, education, and training. Additionally, in times of digital transformation, businesses are promoting employee engagement evermore, particularly in the present context of crises and instability. The research intends to investigate this issue from the viewpoint of employee soft skills. We specifically look into the link between employees’ soft skills and workplace engagement. While doing our research in two different countries, we distinguish between commercial and non-commercial organizations as well as add an international perspective. Based on an acknowledged European skills framework, we focus our study on such soft skills as teamwork, communication, and conflict management and use recognized surveys to quantify them. We use a well-known Gallup methodology to evaluate employee engagement. Using correlation analysis, we investigate the impact of the three selected skills on employee engagement while considering the organization type and country, factors that may play an important role in the digital transformation of businesses and companies.

These OSINT and SOCMINT technologies use sophisticated techniques and special tools to efficiently analyze the continually growing sources of information. There is a great need for training and further education in the OSINT field worldwide. This report describes the importance of open source or social media intelligence for evaluating disaster management. It also gives an overview of the government work in Australia, Haiti, and Japan for disaster management using various OSINT tools and platforms. Thus, decision support for using OSINT and SOCMINT tools is given, and the necessary training needs for investigators can be better estimated.

This PoC work combines the open data from Reddit and the part of the state-of-the-art BERT model. Using the PRAW Python library, the project fetches comments and posts of users. Then these texts are converted into a feature vector - representation of all user posts and comments. The main idea here is to create a comparable user's pair similarity score based on their comments and posts. For example, if we fix one user and calculate scores of all mutual pairs with other users, we will produce a total order on the set of all mutual pairs with that user. This total order can be described as a degree of written similarity with this chosen user. A set of "similar" users for one particular user can be used to recommend to the user interesting for him people. The similarity score also has a "transitive property": if $user_1$ is "similar" to $user_2$ and $user_2$ is similar to $user_3$ then inner properties of our model guarantees that $user_1$ and $user_3$ are pretty "similar" too. In this way, this score can be used to cluster a set of users into sets of "similar" users. It could be used in some recommendation algorithms or tune already existing algorithms to consider a cluster's peculiarities. Also, we can extend our model and calculate feature vectors for subreddits. In that way, we can find similar to the user's subreddits and recommend them to him.

There is more and more information in the public domain. One of the most popular social networks is Twitter. It was chosen to analyze the dependence of changes in the number of likes, reposts, quotes and retweets on the aggressiveness of the post text for a separate profile, as this information can be important not only for the owner of the channel in the social network, but also for other studies that in some way influence user accounts and their behavior in the social network. Furthermore, this work includes a detailed analysis and evaluation of the Tweety library capabilities and situations in which it can be effectively applied. Lastly, this work includes the creation and description of a compiled neural network whose purpose is to predict changes in the number of likes, reposts, quotes, and retweets from the aggressiveness of the post text for a separate profile.

Close to People. Proceedings of the 68th Annual Meeting of the German Association of Medical Informatics, Biometry, and Epidemiology e.V. (gmds) 2023, Heilbronn, Germany N2 - In industrialised countries, one in ten patients suffers harm during hospitalization. Critical Incident Reporting Systems (CIRS) aim to minimize this by learning from errors and identifying potential risks. However, a lack of interoperability among the 16 CIRS in Germany hampers their effectiveness.

As a result, the will to optimize new and existing energy systems extends from private individuals to companies and even entire communities. This work describes the development and usage of a new software called FINEconcepts which creates a digital twin of an energy system. This virtual model can then be used to optimize the energy system based on annual costs, CO2 emissions or other relevant criteria such as self-sufficiency. Because all system components, which include renewable technologies as well, can be added as a building block with chosen but changeable parameters, the software allows the user to explore and awaken interest and understanding of technologies that were previously considered too costly, irrelevant, or unrealistic. Implemented projects in small and large companies as well as in residential areas did prove, that the usage of FINEconcepts leads not only to more efficient energy systems by increasing the use of renewable energy, but also increased knowledge and understanding in terms of energy. Besides economics, ecology and security, understanding is an equally important factor in achieving a sustainable energy supply.

Using a discretization of the terminal density, we write these integral equations as a system of linear equations. We show that the kernel matrix of this system is, in general, ill-conditioned, so that it cannot be solved for the discretized density using a naive approach. Instead, we construct a sparse model for the kernel matrix using singular value decomposition (SVD), which allows us not only to systematically improve the condition number of the kernel matrix, but also determines the computational effort and accuracy of our method. In order to allow for the treatment of realistic inputs that may contain arbitrage, we reformulate the system of linear equations as an optimization problem, in which the SVD-transformed density minimizes the error between the input prices and the arbitrage-free prices generated by our method. To further stabilize the method in the presence of noisy input prices or arbitrage, we apply an 𝐿1-regularization to the SVD-transformed density. Our approach, which is inspired by recent progress in theoretical physics, offers a flexible and efficient framework for the arbitrage-free interpolation of plain-vanilla option prices and implied volatilities, without the need to explicitly specify a stochastic process, expansion basis functions or any other kind of model. We demonstrate the capabilities of our method in a number of artificial and realistic test cases.
