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- The fast-paced digitalization and automation make hard skills acquired by employees in their academic study programs outdated and irrelevant very fast.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.

PSP is the estimation of the 3D structure of a protein, generally through deep learning architectures. Information about the geometry of the protein chain has been proven to be crucial for accurate predictions of 3D structures. However, this information is usually flattened as machine learning features that are not representative of the geometric nature of the problem. Leveraging recent advances in geometric deep learning, we redesign the 3D projector part of a PSP architecture with the addition of CGENN layers . CGENNs can achieve better generalization and robustness when dealing with data that show rotational or translational invariance such as protein coordinates, which are independent of the chosen reference frame. CGENNs inputs, outputs, weights and biases are objects in the Geometric Algebra of 3D Euclidean space, i.e. G3,0,0, and hence are interpretable from a geometrical perspective. We test 6 approaches to PSP and show that CGENN layers increase the accuracy in term of GDT scores by up to 2.1\%, with fewer trainable parameters compared to linear layers and give a clear geometric interpretation of their outputs.

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.

Smectic freely-suspended films can wrinkle like solid sheets. This has been demonstrated earlier with shape-fluctuating smectic bubbles. Here, we exploit the collapse of smectic catenoid films with a central equatorial film to expose the latter to rapid lateral compression. Wrinkle formation is observed in the planar film and the thickness dependence of the undulation wavelength is measured. In addition to the central film, its border undergoes an undulation instability as well.

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.

T1 - Pressure evolution of electronic structure and magnetism in the layered van der Waals ferromagnet CrGeTe3 JF - Physical Review B N2 - Layered van der Waals ferromagnets, which preserve their magnetic properties down to exfoliated monolayers, are fueling an abundance of fundamental research and nanoscale device demonstration. CrGeTe3 is a prime example of this class of materials. Its temperature-pressure phase diagram features an insulator-to-metal transition and a significant increase in ferromagnetic Curie-Weiss temperatures upon entering the metallic state. We use density functional theory to understand the magnetic exchange interactions in CrGeTe3 at ambient and elevated pressures. We calculate Heisenberg exchange couplings, which provide the correct ferromagnetic ground state and explain the experimentally observed pressure dependence of magnetism in CrGeTe3. Furthermore, we combine density functional theory with dynamical mean-field theory to investigate the effects of electronic correlations and the nature of the high-pressure metallic state in CrGeTe3.

This applies especially to the field of sustainable digitalization. The literature providesgaps in the combination of sustainable digitalization with learning, due to the rapid developments and innovationsin this field.AI-based Chatbots could be a solution to rapidly build knowledge in this fast-evolving field, as they are able to drawupon a large body of recent knowledge and allow personalized, individual learning. They are created to understandquestions and respond to users via text, voice, or avatar in an interactive manner to facilitate learning (AI-Abdullatif,2023). Thus, AI-based Chatbots could enhance student-centered e-learning, which has shown to be a valuable toolfor sustainability literacy (Diamond & Irwin, 2013). Nonetheless, existing research does not yet provide sufficientevidence on what learning outcomes (e.g., knowledge acquisition) can be achieved with this AI-based approach tolearning. Therefore, it is crucial for us to determine whether and how they can be effectively utilized for this purpose.In this study, we examine the impact of AI-based Chatbots on learning outcomes in the context of sustainabledigitalization, in comparison to conventional digital learning methods. We conduct a field experiment with a pre-and post-test assessing the respective level of knowledge and sustainability-related competencies amongparticipants. The participants of the study (N=269) engage with different types of supported learning activitiesrelated to sustainable development. Participants are randomly assigned to one of four advanced learningtechnologies: a) AI-assisted personal tutoring (Chatbot), b) non-AI-based conversational learning and c) interactivevideo with embedded activities. Variations in learning outcomes depending on design characteristics of the learningactivity will be measured using the Self-Perceived Action Competence for Sustainability Questionnaire (SPACS-Q)(Olsson et al., 2020) as well as as well as a set of questions to assess knowledge retention.Results indicate that AI-based chatbots may be a viable method to enhance knowledge about practices in sustainabledigitalization. However, sustainability action competencies, such as confidence in one's own influence on shaping amore sustainable future and the willingness to undertake concrete actions, which may require higher-order learningprocesses, are not positively affected by short learning activities with our AI-based chatbot. We found evidence thatnon-AI-based learning activities yield similar increases in building knowledge on sustainable digitalization but alsosignificantly enhance sustainability action competencies related to potential behavioral changes.What does learner-centered pedagogy look like in reimagining the digital classroom of the future?93Assuming that our results are generalizable to other learning topics, the evidence found in this study suggests thatAI-based chatbots can contribute to addressing our most significant transformational challenges, all characterizedby a rapidly evolving knowledge base. Further research is particularly needed with respect to the preferable designcharacteristics of digital learning activities (both AI-based and non-AI-based) to achieve optimal outcomes in buildingsustainability competencies.

In this paper, the method is applied for the rapid evaluation of freshness and monitoring the aging of animal meat and fish. A novel chromatographic sensor was developed with a deep UV LED-based photometric detection unit (255–265 nm), an original flow cuvette and registration scheme; the processing of a chromatogram with the sensor takes approximately 15 min. Strict isochronism between the elution of ATP metabolites, mainly hypoxanthine (Hx) and inosine monophosphate (IMP), and the time of maturation of meat or fish, was discovered. A new freshness index H* = [Hx]/[IMP] was introduced, which is proportional to the instrumental delay time in the FPMLC chromatograms: the H* index < 0.5 indicates the presence of inosine monophosphate (IMP) and the high quality of the meat or fish. Reasonably strong correlations were revealed between data obtained by FPMLC and total volatile basic nitrogen TVB-N (for fish) or volatile fatty acids VFA (for meat) content. Moreover, putative nucleotide salvage and an increase in the concentration of IMP were observed in fish after heat treatment using the FPMLC sensor and NMR technique.
