However, an increase in population tends to put a strain on existing education systems, especially in Africa where most countries are characterized by slow economic development, rapid population growth rates and a median age just shy of 20 years. Due to the slow rate of economic growth, many African countries lack the financial capability to provide proper education for their ever-growing populations or even already overpopulated regions, many of which have people who have reached the appropriate school-going age. This leads to a series of disruptive impacts on the education systems resulting in a people who are poorly or improperly educated, and thus are not equipped with the necessary skills required for the vast technical, professional and ever modernizing high-skill job markets such as construction, economic and technical professions, teaching occupations and so on, all of which drive economic growth and development. Therefore, we can see that rapid population growth, if left unchecked, may lead to overpopulation scenarios which could have a negative disruptive impact on education and human development, both of which are important factors necessary for economic growth. Key words: Population, education, Africa, poverty, economy, development.}, subject = {{\"U}berv{\"o}lkerung}, language = {en} } @techreport{ReimannShettyKlechaetal.2023, author = {Reimann, Christoph and Shetty, Darshan and Klecha, Dominik and Munaf, Jasmin and Boateng, Newell}, title = {Absence of external resources in Germany}, doi = {10.25933/opus4-2892}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-28928}, pages = {III, 30 Seiten}, year = {2023}, abstract = {This scientific paper deals with the question of to what extent the deglobalization of raw materials will have an impact on Germany. For this purpose, a general understanding of the terms "globalization" and "deglobalization" will be provided. In addition, the drivers and challenges of (de)globalization are explained in more detail. The question was then examined based on specific case studies, which are decisive for today's prosperity and are predominantly imported. This includes gases, oils, and rare earths. The paper distinguishes between the effects of a loss of these resources on Germany, if the deglobalization takes place slowly and planned or unplanned and fast. The effects are then considered at three different levels: at the government level, at the corporate level, and at the population level. At the corporate level, the focus was primarily on the largest German industries. Each of the case studies ends with possible hypothetical scenarios that do not have to happen but could happen in the worst case. The scenarios show how bad things can get and provide an answer to the scientific question of how deglobalization in the case study could affect Germany.}, subject = {Nat{\"u}rliche Ressourcen}, language = {en} } @article{PufalShunBenAmmaretal.2023, author = {Pufal, Jakob and Shun, Hanna and Ben Ammar, Rami and Jeckstadt, Janik and Schultheiß, John}, title = {The Great Shutdown}, doi = {10.25933/opus4-2894}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-28942}, pages = {II, 17, VI Seiten}, year = {2023}, abstract = {This research aims to examine the potential impact of a military escalation of the China-Taiwan conflict on global economies, with a particular focus on the microchip production industry in Taiwan.

The study focuses on two main areas: the weakening of the media and the emergence of "smart dictatorship." The paper examines the ways in which AI can be used to supervise, manipulate, and frustrate the media, thereby weakening its role as a check on government and corporate power. The study also explores how AI technology can be used to create an "omnidirectional monitoring" society, where individuals are constantly monitored and controlled through the use of "panopticon" techniques and "social bots". This can lead to the emergence of a "postdemocratic" society, characterized by growing inequality, dehumanization, and the manipulation of information on online media platforms. The research methodology adopted in the study is qualitative, using expert interviews with three experts who discussed the overall use of AI and its disruptive effects on democracy, such as the creation of fake news, filter bubbles, and algorithm bias.

Recorded data, including textual data and event log, expand exponentially, complicating decision-making and posing new challenges for BP complexity analysis in Business Process Management (BPM). Herein, Process Mining (PM) serves to derive insights based on historic BP execution data, called event log. However, in PM, textual data is often neglected or limited to BP descriptions. Therefore, in this study, we propose a novel approach for analyzing BP execution complexity by combining textual data serving as an input at the BP start and event log. The approach is aimed at studying the connection between complexities obtained from these two data types. For textual data-based complexity, the approach employs a set of linguistic features. In our previous work, we have explored the design of linguistic features favorable for BP execution complexity prediction. Accordingly, we adapt and incorporate them into the proposed approach. Using these features, various machine learning techniques are applied to predict textual data-based complexity. Moreover, in this prediction, we show the adequacy of our linguistic features, which outperformed the linguistic features of a widely-used text analysis technique. To calculate event log-based complexity, the event log and relevant complexity metrics are used. Afterward, a correlation analysis of two complexities and an analysis of the significant differences in correlations are performed. The results serve to derive recommendations and insights for BP improvement. We apply the approach in the IT ticket handling process of the IT department of an academic institution.

The participants underwent measurements of the mediolateral displacement three times using the Patellostabilome- ter. A maximal force of 10 N was applied for patella movement. Additionally, leg length and circumference of the knee, upper- and lower-leg were measured. Lateral patella displacement of 18.27 ± 3.76 mm (range 15.85-20.64 mm, interquartile range (IQR) of 4.79) was measured. The medial patella displacement showed 24.47 ± 6.59 mm (range 19.29-29.76 mm, IQR of 10.47). The test-retest measurement error was 2.32 ± 1.76 mm (IQR of 2.38 mm), with five outliers. There was greater test-retest variability between the measurements of the medial displacement compared to the lateral one. The test-retest variability reached 7\% of the patella displacement.

At the same time, data analytics has been fuelled by the availability of immense amounts of textual data. Whilst both co-creation and TA have been used in the private sector, we study existing works on the application of Text Analytics (TA) techniques on text data to support public service co-creation. We systematically review 75 of the 979 papers that focus directly or indirectly on the application of TA in the context of public service development. In our review, we analyze the TA techniques, the public service they support, public value outcomes, and the co-creation phase they are used in.

The flow has been considered to be radial, incompressible and laminar. The time-dependent Navier-Stokes equation has been solved in cylindrical coordinates using Fourier transform, and the oscillating flow velocity across the thickness of the cell has been obtained at different times. The flow velocity function in the unsteady state is related to the vertical component of the coordinates in the form of parabolic functions and also to the inverse of the radial component. The time dependence appears as a simple harmonic with a frequency equal to the oscillation frequency. The velocity of the flow is maximum at the middle of the cell along its height and gradually decreases from the middle towards the top or bottom plane and reaches zero. Pressure does not depend on the height and changes logarithmically with the radius. The dependence of pressure on time is also a simple harmonic with the external frequency, but it has a phase shift with respect to the velocity.}, language = {en} } @inproceedings{SoniNeubertDietrichetal.2023, author = {Soni, Jaykumar and Neubert, Tom and Dietrich, Benjamin and Vielhauer, Claus}, title = {Virtual Sessions for Forensic Analysis of Video Conferencing Systems: A Novel Methodology}, series = {Konferenz: IARIA SECURWARE 2023, the Seventeenth International Conference on Emerging Security Information, Systems and Technologies: Porto, Portugal}, booktitle = {Konferenz: IARIA SECURWARE 2023, the Seventeenth International Conference on Emerging Security Information, Systems and Technologies: Porto, Portugal}, publisher = {IARIA}, pages = {18 -- 20}, year = {2023}, language = {en} } @article{HascheKaraschewskiCreutzburg2023, author = {Hasche, Eberhard and Karaschewski, Oliver and Creutzburg, Reiner}, title = {iPhone12 imagery in scene-referred computer graphics pipelines}, series = {Electronic Imaging}, journal = {Electronic Imaging}, publisher = {Society for Imaging Science and Technology}, doi = {10.2352/EI.2023.35.3.MOBMU-350}, pages = {350-1 -- 350-14}, year = {2023}, abstract = {With the release of the Apple iPhone 12 Pro Max in 2020, various features were integrated that make it attractive as a recording device for scene-related computer graphics pipelines.

The absorption and re-emission spectra of each cascade layer depend on the characteristics of the material used. Сolloidal quantum dots are among the most promising materials for cascade layers due to their manufacturing technology, which provides for accurate control over the photoluminescence maximum position. It seems highly relevant to develop and to study photosensitive structures with cascade concentrators of various shapes based on CdS, CdSe/ZnS, and PbS colloidal quantum dots. Aim . To develop photosensitive structures with a wide-range sensitivity spectrum based on concentrators containing arrays of metal chalcogenide CQDs and to study their characteristics. Materials and methods . Cascade photosensitive structures were manufactured based on layers made of polymethyl methacrylate and layers of colloidal quantum dots embedded in a polystyrene matrix. Results . Three-layer concentrators were manufactured with different colloidal quantum dots in each concentrator layers. A 22 \% increase in the output power was observed for a three-layer cascade structure based on different cascade layer materials compared to a similar structure using a single layer concentrator.

The paper provides some insights on how these measures can be implemented in practice, how to support business unit developers to efficiently deliver productive results, and how to evaluate LCDP-based development processes.}, language = {en} } @inproceedings{FroschLevina2023, author = {Frosch, Katharina and Levina, Olga}, title = {Taking the Matter in their own Hands - Can Business Unit Developers Fullfill their Digital Demands with Low-Code Development Platforms?}, series = {Konferenz: IARIA ICDS 2023, The Seventeenth International Conference on Digital Society; Venice (Italy)}, booktitle = {Konferenz: IARIA ICDS 2023, The Seventeenth International Conference on Digital Society; Venice (Italy)}, publisher = {IARIA}, pages = {1 -- 4}, year = {2023}, abstract = {Low Code Development Platforms (LCDP) often promise an easy and fast way to include data processing and support into the otherwise non-digital process. Nevertheless, it often remains unclear, besides anecdotal evidence, how business users are getting on with transformation of business requirements into the software. This research explores the potential low code development has for business users to address their needs for process support via software tools. The experiment was chosen as the research method to assess the feasibility of software development with LCDP by novices. The results point towards a dedicated LCDP implementation approach if the technology is to be implemented in the business context. Hence, the research provides suggestions on how Business Unit Developers (BUD) can be supported to efficiently deliver productive results and how to assess LCDP-based development process and points towards potential challenges of LCDP implementation.}, language = {en} } @inproceedings{LemkeMeisterWessels2023, author = {Lemke, Claudia and Meister, Vera and Weßels, Doris}, title = {Kritische Reflexion und Handlungsans{\"a}tze zum Einsatz Generativer KI in der Wirtschaftsinformatik-Lehre}, series = {36.

However, as a result of aging, users have different needs and requirements towards the design of the communication application. This paper examines the preferences of users of different ages towards the User Interface (UI) design of Mobile Instant Massage (MIM) applications, i.e., instant message applications that can operate on smartphones. An online survey data about users' preferences towards the UI of this application type, limited to Indonesian users, was obtained. The results indicate that for some UI elements, both age groups showed the same preferences, while other requirements were significantly different. This paper aims to give a better understanding of the interface of the MIM application preferred by its users according to their age and thus inform application designers and product owners.}, language = {en} } @incollection{MingioneKristal2023, author = {Mingione, Michela and Kristal, Samuel}, title = {Brand value co-creation: field emergence, applications, measurement and future research directions}, series = {A Research Agenda for Brand Management in a New Era of Consumerism}, booktitle = {A Research Agenda for Brand Management in a New Era of Consumerism}, publisher = {Edward Elgar Publishing}, address = {Cheltenham, UK}, doi = {10.4337/9781803925516.00013}, pages = {89 -- 106}, year = {2023}, language = {en} } @book{Brasche2023, author = {Brasche, Ulrich}, title = {Climate justice and the Global South - The road to solving climate change}, publisher = {Books on Demand}, isbn = {Print 9783758302381}, pages = {172}, year = {2023}, abstract = {Climate will be decided in the global south Mankind is on a dangerous journey in the Anthropocene. Arriving at a good life for all within planetary boundaries is still possible. But at present, the journey is more likely to lead to an overheating of the Earth. Health and life would then be massively endangered for many living beings - including humans. A positive development is still possible, but it requires a global transformation of the economy and society. The prosperous states and companies are well advised, to respect the interests of the global south and future generations, and to use wisely the considerable financial resources in a cooperation of equals. This book • highlights past carbon emissions and their consequences, • reflects on the main drivers of future emissions, • discusses strategies like green growth, de-growth, • presents market-based instruments like carbon trading and carbon border adjustment and • emphasises the key role played by the emerging countries of the global south. It is not only a matter of justice but furthermore in the interest of the rich countries in the global north to contribute massively to financing a "green leapfrogging" of the global south into a carbon-free prosperity. Failing to achieve it will bring unspeakable losses and suffering to many people all over the planet.}, language = {en} }
