Due to the global phenomenon of climate change the region of Mara Siana is projected to increasingly face extreme weather events that particularly comprise prolonged droughts and
heavier rainfalls. To be able to adequately adapt to these changing circumstances and maintain their livelihoods communities need to build respective capacities. As the main objective, this research aims at determining landowners’ climate change adaptative capacity (CCAC) across different villages in Mara Siana. Accordingly, a semi-quantitative approach was carried out including qualitative interviews and the subsequent quantitative calculation of CCAC based on a multidimensional indicator set and a respective coding
system. In addition to predominantly positive results of socio-cultural characteristics and the quality of natural resources, this work reveals clear weaknesses and potential for improvement in the areas of income security and financial stability, the expansion and resilience of infrastructure, and the relationship between communities and local authorities. Moreover, differences in capacity results are not only identified between the investigated villages as well as between individual households but also systemic disadvantage in capacity building affecting female landowners and community members can be indicated from the obtained interview data. Therefore, this research gives concrete recommendations for the implementation and verification of suitable adaptive measures that are particularly tailored for the improvement of low-performance indicators while following a gendertransformative approach and thus hold the potential to increase CCAC in the long-term.
Zielsetzung der Studie war die Erhebung der Betroffenheit von Pflegeverantwortung des wissenschaftlichen Personals, die Bewältigungsformen und die beruflichen und gesundheitlichen Konsequenzen am Beispiel der Georg-August-Universität Göttingen. Im Mixed-Methods-Forschungsdesign wurden qualitative Interviews mit zentralen Akteuren der Universität (N=16) mit einer quantitativen Online-Erhebung am wissenschaftlichen Personal (N=967) kombiniert. Die Ergebnisse zeigen, dass 16% des wissenschaftlichen Personals zum Befragungszeitpunkt von Pflegeverantwortung betroffen waren, teilweise mit erheblichen gesundheitlichen Konsequenzen sowie einem insgesamt sehr hohem Mental Load. Rund die Hälfte der Wissenschaftler*innen antizipiert eine Pflegeverantwortung sicher oder wahrscheinlich für die nächsten Jahre. Die qualitativen Interviewergebnisse zeigen eine gestiegene Wahrnehmung der Relevanz von Pflege-/Sorgeverantwortung an der Universität. Gleichzeitig wurde deutlich, dass Pflegeverantwortung deutlich weniger sichtbar ist als die Sorge um Kinder und auch kaum durch konkrete Maßnahmen adressiert wird. Die Ergebnisse münden in Handlungsempfehlungen zur Verbesserung der Vereinbarkeit von wissenschaftlicher Laufbahn und der Sorge-/Pflegeverantwortung für Angehörige.
Acknowledging the ways in which design (as practices, forms of knowledge, and sets of objects) is accountable for ongoing social and environmental injustices, this anthology contains contributions that envision alternative ways of exploring and designing more livable futures. Attending to these futures requires a reckoning with a multiplicity of actors and contexts, from institutional norms and regulations, to pedagogies, curricula, programs, digital tools, infrastructures, and architectural environments. Last but not least, attention is drawn to the mechanisms and protocols by which these futures are imagined and shaped. This includes critically examining the ways in which design is talked about, taught, and learned in order to empower future designers to engage with the political issues, cultural conditions, and social and environmental implications of their work.
Diese Arbeit untersucht die Transformation des Point of Sale im Lebensmitteleinzelhandel durch die Implementierung intelligenter Regalsysteme. Angesichts der zunehmenden Digitalisierung im Einzelhandel konzentriert sich die Untersuchung auf die technische Implementierung sowie die ökonomische und ökologische Bewertung dieser innovativen Systeme. Die Forschung wurde durch eine Kombination aus Literaturrecherche, Experteninterviews und Feldforschung durchgeführt. Die Literaturrecherche diente dazu, ein fundiertes Verständnis der technischen Grundlagen und Architekturen intelligenter Regalsysteme zu erlangen, während die Experteninterviews tiefe Einblicke in deren praktische Anwendung und ökonomische Implikationen lieferten. Die Feldforschung, fokussiert auf Supermärkte in der Region Köln, validierte die theoretischen Erkenntnisse und bot praktische Perspektiven auf die Nutzung dieser Technologie. Die Ergebnisse zeigen, dass intelligente Regalsysteme signifikante ökonomische Vorteile bieten, indem sie die Effizienz und Kundenerfahrung verbessern. Allerdings bestehen Herausforderungen bei der Integration in bestehende IT-Infrastrukturen sowie in Bezug auf Datenschutz und Sicherheit. Die ökologische Nachhaltigkeit dieser Systeme wurde kritisch hinterfragt, wobei die Expertenmeinungen variieren. Die Arbeit prognostiziert, dass intelligente Regalsysteme in den nächsten 5-10 Jahren weiterentwickeln und durch Innovationen wie KI, NLP und Blockchain-Technologie erweitert werden. Diese Entwicklungen prägen den Lebensmitteleinzelhandel und bieten ökonomische Vorteile. Die Vorteile für Nachhaltigkeit lassen sich nach einigen Experten
hinterfragen. Diese Studie leistet einen wichtigen Beitrag zur aktuellen Forschung im Bereich der Wirtschaftsinformatik und bietet praktische Einblicke für Akteure im Lebensmitteleinzelhandel. Sie hebt die Bedeutung einer strategischen Herangehensweise bei der Implementierung dieser Technologien hervor und betont die Notwendigkeit, die Balance zwischen technologischen Innovationen und menschlichen Aspekten des Einkaufserlebnisses zu finden. Die Untersuchung lässt einen Trend hinsichtlich der Entwicklung und verbreitung intelligenter Regalsysteme erkennen.
The 16th Annual Meeting of the Sponsoring Group Reinsurance [Förderkreis Rückversicherung] was held 16 June 2023 in Niederkassel, near Cologne. Some 90 representatives of the (re)insurance companies involved in the Sponsoring Group
took part in the meeting, along with guests. Offered for the ninth time as part of the Annual Meeting, the Researchers’ Corner gave the six academic researchers at the Cologne Research Centre for Reinsurance an opportunity to deliver a presentation on the research project in which each is involved in 2023. Over the course of three sessions, the most important results of the scientific studies by the Cologne Research Centre for Reinsurance were presented and discussed.
The heterogeneity of the topics presented reflects the dovetailing of Cologne Research Centre with reinsurance practice.

Proceedings des Researchers‘ Corner zur 16. Jahrestagung des Förderkreises Rückversicherung 2023
(2023)
Am 16. Juni 2023 fand die 16. Jahrestagung des Förderkreises Rückversicherung in Niederkassel bei Köln statt. Etwa 84 Repräsentanten der in dem Förderkreis mitwirkenden (Rück-) Versicherungsunternehmen und Gäste nahmen daran teil. Im Rahmen der Jahrestagung wurde zum neunten Mal der Researchers‘ Corner durchgeführt, in dessen Verlauf die sechs wissenschaftlichen Forscher*innen der Kölner Forschungsstelle Rückversicherung je einen Vortrag zu dem jeweils bearbeiteten Forschungsprojekt 2023 hielten.
In drei Sessions wurden die wichtigsten Ergebnisse der wissenschaftlichen Untersuchungen der Kölner Forschungsstelle Rückversicherung präsentiert und diskutiert. Die Heterogenität der vorgetragenen Themen spiegelt die Verzahnung der Kölner Forschungsstelle mit der Rückversicherungspraxis wider.
In its Renewables 2022 Report, the International Energy Agency (IEA) projects that the share of renewable energies in the global energy mix will increase from 22.8% in 2015 to 38.1% in 2027. This trend goes hand-in-hand with increasing construction of plants for the generation of renewable energies, leading to increased demand for (re)insurance. Comparable to the development of traditional energy sources, the hedging of current risks is a key element in the further development of renewable energies. According to projections by the IEA, by 2027 most of the energy from renewable sources will be generated using photovoltaics or solar as well as onshore and offshore wind.
Die Handelsspannungen zwischen den USA und China, die sich seit Anfang 2017 verschärft haben, hatten weitreichende Folgen. Am 6. Juli 2018 verhängten die USA Zölle auf chinesische Waren im Wert von 34 Mrd. USD, was Maßnahmen seitens Chinas nach sich zog. Dieser anhaltende Handelsstreit hat zu wirtschaftlichen Spannungen zwischen den beiden größten Volkswirtschaften der Welt geführt, die sich in der Einführung von Zöllen, Handelsbeschränkungen und geopolitischen Unsicherheiten niederschlagen. Die Auswirkungen dieser Maßnahmen waren in verschiedenen Sektoren spürbar und führten zu Unterbrechungen in den globalen Lieferketten, erhöhten Produktionskosten und Nachfrageschwankungen auf den Märkten. Unternehmen, die in diesem komplexen Handelsumfeld tätig sind, sehen sich nun mit erheblichen Unsicherheiten konfrontiert. Die Automobilindustrie, einschließlich Autos, Autoteile, Stahl und Aluminium, ist besonders betroffen.
Das Forschungsprojekt dieses Jahres betont die Verbindung von Theorie und Praxis bei der Analyse der Interaktionen von Marktteilnehmern im Rückversicherungsmarkt. Im Fokus stehen mathematische/aktuarielle Ansätze, insbesondere im Kontext "Optimaler Rückversicherungsverträge". Die Schwierigkeit besteht darin, Erkenntnisse in den Marktalltag zu übertragen. Market Design wird als Schlüssel betrachtet, um greifbare Erkenntnisse zu generieren. Der Bericht stellt Fragen zur Motivation der Marktteilnehmer, den Zielen und Strategien. Eine empirische Befragung der Spieler könnte Einblicke in deren Entscheidungsprozesse liefern. Die Dynamiken im Markt, insbesondere im Hinblick auf Erneuerungszyklen und Retrozessionen, werden ebenfalls diskutiert. Schließlich betont der Bericht die Bedeutung von guten Spielregeln, um asymmetrische Informationen zu minimieren und das kollektive Nutzen von Markt und Gesellschaft zu fördern.
The prolonged US-China trade tension, initiated in 2017, has led to significant consequences, impacting global supply chains and causing economic tension between the two largest economies. Particularly affecting the automotive sector, the trade war has influenced motor insurance premiums in China, contributing to a declining trend in non-life insurance growth rates from 2017 to 2021. However, a positive outlook is projected for 2023-2026, indicating potential recovery opportunities. The trade war's short-term impacts on the Chinese motor insurance market include increased costs, low premium growth, and economic challenges. In the long term, transformative changes, including market diversification, innovative products, data-driven pricing, and technology-enabled risk prevention, are expected to shape a dynamic and competitive motor insurance landscape in China, offering growth potential despite initial challenges.
Die Reihe „Basiswissen zur Nachhaltigkeit“ versucht zu verschiedenen Themen der Nachhaltigkeit, z.B. Klimawandel, Abfallproblematik, soziale Gerechtigkeit, grundlegende Fakten zusammenzustellen. Zielsetzung ist es ein Grundwissen bereitzustellen, das zum einen als Ausgangspunkt für vertiefende Analysen dient und zudem eine faktenbasierte Grundlage für die eigene Meinungsbildung sein kann.

Nach einem Überblick über die natürlichen und menschengemachten Ursachen des Klimawandels werden die weltweiten Temperaturziele und daraus abgeleiteten CO2-Restbudgets dargestellt und hinsichtlich ihrer Realisierbarkeit analysiert. Der letzte Teil behandelt die Strategien und Instrumente zur Bewältigung des Klimawandels weltweit und in Deutschland.
In this work, we propose a novel data-driven approach to recover missing or corrupted motion capture data, either in the form of 3D skeleton joints or 3D marker trajectories. We construct a knowledge-base that contains prior existing knowledge, which helps us to make it possible to infer missing or corrupted information of the motion capture data. We then build a kd-tree in parallel fashion on the GPU for fast search and retrieval of this already available knowledge in the form of nearest neighbors from the knowledge-base efficiently. We exploit the concept of histograms to organize the data and use an off-the-shelf radix sort algorithm to sort the keys within a single processor of GPU. We query the motion missing joints or markers, and as a result, we fetch a fixed number of nearest neighbors for the given input query motion. We employ an objective function with multiple error terms that substantially recover 3D joints or marker trajectories in parallel on the GPU. We perform comprehensive experiments to evaluate our approach quantitatively and qualitatively on publicly available motion capture datasets, namely CMU and HDM05. From the results, it is observed that the recovery of boxing, jumptwist, run, martial arts, salsa, and acrobatic motion sequences works best, while the recovery of motion sequences of kicking and jumping results in slightly larger errors. However, on average, our approach executes outstanding results. Generally, our approach outperforms all the competing state-of-the-art methods in the most test cases with different action sequences and executes reliable results with minimal errors and without any user interaction.
Austria is committed to the net-zero climate goal along with the European Union. This requires all sectors to be decarbonized. Hereby, hydrogen plays a vital role as stated in the national hydrogen strategy. A report commissioned by the Austrian government predicts a minimum hydrogen demand of 16 TWh per year in Austria in 2040. Besides hydrogen imports, domestic production can ensure supply. Hence, this study analyses the levelized cost of hydrogen for an off-grid production plant including a proton exchange membrane electrolyzer, wind power and solar photovoltaics in Austria. In the first step, the capacity factors of the renewable electricity sources are determined by conducting a geographic information system analysis. Secondly, the levelized cost of electricity for wind power and solarphotovoltaics plants in Austria is calculated. Thirdly, the most cost-efficient portfolio of wind power and solar photovoltaics plants is determined using electricity generation profiles with a 10-min granularity. The modelled system variants differ among location, capacity factors of the renewable electricity sources and the full load hours of the electrolyzer. Finally, selected variables are tested for their sensitivities. With the applied model, the hydrogen production cost for decentralized production plants can be calculated for any specific location. The levelized cost of hydrogen estimates range from 3.08 EUR/kg to 13.12 EUR/kg of hydrogen, whereas it was found that the costs are most sensitive to the capacity factors of the renewable electricity sources and the full load hours of the electrolyzer. The novelty of the paper stems from the model applied that calculates the levelized cost of renewable hydrogen in an off-grid hydrogen production system. The model finds a cost-efficient portfolio of directly coupled wind power and solar photovoltaics systems for 80 different variants in an Austria-specific context.
Abstract
Even though researchers are increasingly acknowledging the dark side of customer participation (i.e., behavioral customer engagement), particularly in professional services with high cognitive demands that cause customer participation stress (i.e., negative psychological state resulting from the customer's overextension by required customer participation efforts), insights on how firms can effectively mitigate customer participation stress remains limited. Building on transactional stress theory, we investigate whether customers can effectively cope with the expected cognitive demands of professional services. Moreover, by introducing an adapted coping construct (i.e., coping support), we examine whether employees can provide coping support to help decrease customer participation stress. The findings of a time‐lagged field study with customers of a large German bank (N = 117) suggest that customer coping before the encounter cannot mitigate the effect of anticipated cognitive demands on customer participation stress. Instead, the results of both the field study and a follow‐up experimental study (N = 218) show that a certain set of employee coping support during service encounters is crucial. While focusing on action coping support is not ideal in situations with high cognitive demands, firms should advise their professional service employees to offer emotional coping support to attenuate the unfavorable effect of cognitive demands on customer participation stress.
As the population ages, the demand for care for older adults is increasing. To maintain their independence and autonomy, even with declining health, assistive technologies such as connected medical devices or social robots can be useful. In previous work, we introduced a novel health monitoring system that combines commercially available products with apps designed specifically for older adults. The system is intended for the long-term collection of subjective and objective health data. In this work, we present an exploratory user experience (UX) and usability study we conducted with older adults as the target group of the system and with younger expert users who tested our msystem. All participants interacted with a social robot conducting a health assessment and tested sensing devices and an app for data visualization. The UX and usability of the individual components of the system were rated highly in questionnaires in all sessions. All participants also said they would use such a system in their everyday lives, demonstrating the potential of these systems for self-managing users’ health. Finally, we found factors such as previous experience with social robots and technological expertise to have an influence on the reported UX of the users.
To date, the establishment of high-titer stable viral packaging cells (VPCs) at large scale for gene therapeutic applications is very time- and cost-intensive. Here we report the establishment of three human suspension 293-F-derived ecotropic MLV-based VPCs. The classic stable transfection of an EGFP-expressing transfer vector resulted in a polyclonal VPC pool that facilitated cultivation in shake flasks of 100 mL volumes and yielded high functional titers of more than 1 × 106 transducing units/mL (TU/mL). When the transfer vector was flanked by transposon terminal inverted repeats (TIRs) and upon co-transfection of a plasmid encoding for the transposase, productivities could be slightly elevated to more than 3 × 106 TU/mL. In contrast and using mRNA encoding for the transposase, as a proof of concept, productivities were drastically improved by more than ten-fold exceeding 5 × 107 TU/mL. In addition, these VPC pools were generated within only 3 weeks. The production volume was successfully scaled up to 500 mL employing a stirred-tank bioreactor (STR). We anticipate that the stable transposition of transfer vectors employing transposase transcripts will be of utility for the future establishment of high-yield VPCs producing pseudotype vector particles with a broader host tropism on a large scale.
In recent years there have been numerous technical innovations such as CGM systems or insulin pumps that have made life easier for people with type 1 diabetes. However, this also means that more and more information is available. The aim of the present study is to find out more about the daily handling of information. The following research question was asked: What information do people with type 1 diabetes use? To answer this research question, a quantitative online survey of people with type 1 diabetes was conducted by Prof. Dr. Matthias Fank at the Technical University of Cologne. The online survey mainly consisted of 25 closed questions, which were asked on a scale from 0 to 10. The responses of 1,025 people who are at least 18 years old were included in the evaluation. The most important information for type 1 diabetics is the "current value". 67.5% have this on Place 1 placed. Current glucose levels are provided by CGM systems used by 94.2% of people with type 1 diabetes. Quarterly visits to the diabetologist are important and provide important information. 30.8% “completely” agree with this statement on a scale from 0 to 10. Only 2.2% of people with type 1 diabetes are satisfied with their current diabetes management apps. There is a desire for a manufacturer-independent app. The strongest agreement with a value of 10 was chosen by almost a quarter (24.6%) of the people with type 1 diabetes. The study provides an insight into diabetes therapy and shows the need for action.
Das Labor für Konstruktionstechnik der Technischen Hochschule Köln beschäftigt sich mit der Mikrodosierung von präzisen Strukturen von Silberleitklebstoff. Hauptsächlich wird bei derartigen Ventilen in berührende und berührungslose Dosierventile unterschieden. Zur Erzeugung dreidimensionaler elektrisch leitfähiger Strukturen können diese Dosierventile an entsprechende Verfahreinheiten adaptiert werden.
Porous polymer membranes substantially contribute to an acceleration of sustainability transformation based on the energy efficient separation of liquid and gaseous mixtures. This rapid shift toward sustainable industrial processes leads to an increased demand for specifically tailored membranes. In order to predict membrane performance factors like permeability, selectivity and durability, the membrane formation process by film casting and phase inversion needs to be understood further. In recent years, computational models of the membrane formation process have been studied intensely. Their high spatial and temporal resolution allows a detailed quantitative description of phase inversion phenomena. New experimental techniques complement this development, as they provide quantitative data, e.g., on compositional changes of the polymer solution during membrane formation as well as the kinetic progression of the phase separation process. This state-of-the-art review compiles computational and experimental approaches that characterize the phase inversion process. We discuss how this methodological pluralism is necessary for improving the tailoring of membrane parameters, but that it is unlikely to be the way to the ultimate goal of a complete description of the evolution of the membrane structure from the initial demixing to the final solidification. Alternatively, we formulate an approach that includes a database of standardized and harmonized membrane performance data based on previously publicized data, as well as the application of artificial neural networks as a new powerful tool to link membrane production parameters to membrane performance.
The Production of Isophorone
(2023)
Isophorone is a technically important compound used as a high-boiling-point solvent for coatings, adhesives, etc., and it is used as a starting material for various valuable compounds, including isophorone diisocyanate, a precursor for polyurethanes. For over 80 years, isophorone has been synthesized via base-catalyzed self-condensation of acetone. This reaction has a complex reaction mechanism with numerous possible reaction steps including the formation of isophorone, triacetone dialcohol, and ketonic resins. This review provides an overview of the different production processes of isophorone in liquid- and vapor-phase and reviews the literature-reported selectivity toward isophorone achieved using different reaction parameters and catalysts.
During spaceflight, humans experience a variety of physiological changes due to deviations from familiar earth conditions. Specifically, the lack of gravity is responsible for many effects observed in returning astronauts. These impairments can include structural as well as functional changes of the brain and a decline in cognitive performance. However, the underlying physiological mechanisms remain elusive. Alterations in neuronal activity play a central role in mental disorders and altered neuronal transmission may also lead to diminished human performance in space. Thus, understanding the influence of altered gravity at the cellular and network level is of high importance. Previous electrophysiological experiments using patch clamp techniques and calcium indicators have shown that neuronal activity is influenced by altered gravity. By using multi-electrode array (MEA) technology, we advanced the electrophysiological investigation covering single-cell to network level responses during exposure to decreased (micro-) or increased (hyper-) gravity conditions. We continuously recorded in real-time the spontaneous activity of human induced pluripotent stem cell (hiPSC)-derived neural networks in vitro. The MEA device was integrated into a custom-built environmental chamber to expose the system with neuronal cultures to up to 6 g of hypergravity on the Short-Arm Human Centrifuge at the DLR Cologne, Germany. The flexibility of the experimental hardware set-up facilitated additional MEA electrophysiology experiments under 4.7 s of high-quality microgravity (10–6 to 10–5 g) in the Bremen drop tower, Germany. Hypergravity led to significant changes in activity. During the microgravity phase, the mean action potential frequency across the neural networks was significantly enhanced, whereas different subgroups of neurons showed distinct behaviors, such as increased or decreased firing activity. Our data clearly demonstrate that gravity as an environmental stimulus triggers changes in neuronal activity. Neuronal networks especially reacted to acute changes in mechanical loading (hypergravity) or de-loading (microgravity). The current study clearly shows the gravity-dependent response of neuronal networks endorsing the importance of further investigations of neuronal activity and its adaptive responses to micro- and hypergravity. Our approach provided the basis for the identification of responsible mechanisms and the development of countermeasures with potential implications on manned space missions.
The European heating sector is currently heavily dominated by fossil fuels. Composting is a naturally occurring process in which heat is liberated from the composting substrate at a higher rate than the process needs to support itself. This difference could be harnessed for low-heat applications such as residential consumption, alleviating some of the impacts fossil fuel emissions represent. In this study, the composting heat recovery reported in the literature was compared to the energy demand for space and water heating in four European countries. A review of potential heat production from the waste representative of the residential sector was performed. We found that the theoretically recoverable composting heat does not significantly reduce the need for district heating. However, it can significantly reduce the energy demand for water heating, being able to supply countries such as Greece with between 36% and 100% of the yearly hot water demand, or 12% to 53% of the yearly hot water of countries such as Switzerland, depending on the efficiency of heat recovery.
The annual yield of bifacial photovoltaic systems is highly dependent on the albedo of the underlying soil. There are currently no published data about the albedo of red soil in western Africa. In this study, the impact of the albedo of red soil in Ghana on the energy yield of bifacial photovoltaic systems is analysed. A bifacial photovoltaic simulation model is created by combining the optical view factor matrix with an electrical output simulation. For an exact simulation, the albedo of red soil at three different locations in Ghana is measured for the first time. The average albedo of every red soil is clearly determined, as well as the measurement span including instrumentation uncertainty; values between 0.175 and 0.335 were measured. Considering these data, a state-of-the-art bifacial photovoltaic system with an average of 19.8% efficient modules in northern Ghana can achieve an annual energy yield of 508.8 kWh/m2 and a bifacial gain of up to 18.3% in comparison with monofacial photovoltaic panels. To summarise, red soil in two out of three locations in Ghana shows higher albedo values than most natural ground surfaces and therefore positively impacts the annual yield of bifacial photovoltaic systems.
Hydroxybenzene, commonly known as phenol, is one of the most important organic commodity chemicals. To produce phenol, the cumene process is the most used process worldwide. A crucial step in this process is the Hock rearrangement, which has a major impact on the overall cumene consumption rate and determines the safety level of the process. The most used catalyst for the cleavage of cumene hydroperoxide (CHP) is sulfuric acid. Besides its strong corrosive property, which increases plant investment costs, it also requires neutralization after the decomposition step to prevent side reactions. In this study, we show that high-temperature-treated Linde Type X (LTX) zeolites exhibit a high activity for the peroxide cleavage step. In addition, the structure–activity relationship responsible for this good performance in the reaction system of the HOCK rearrangement was investigated. XRPD analyses revealed the formation of a new phase after temperature treatment above 900 °C. The Si/Al ratio determined by EDX suggested the formation of extra-framework aluminum, which was confirmed by solid-state NMR analysis. The newly formed extra-framework aluminum was found to be responsible for the high catalytic activity. BET analyses showed that the surface area drops at higher calcination temperatures. This leads to a lower catalytic activity for most known reactions. However, for this study, no decrease in activity has been observed. The newfound material shows extraordinarily high activity as a catalyst in the HOCK cleavage and has the potential to be a heterogeneous alternative to sulfuric acid for this reaction.
Due to its location at the south-west coast of Ireland County (Co.) Cork is frequently affected by post tropical cyclones (PTCs). There have been several records of these post hurricanes in the past with the last severe PTC being Hurricane Ophelia in 2017. It caused severe disruption in the whole country, especially in Co. Cork with several thousand people without water, power and mobile service for up to 10 days and thousands of uprooted trees which blocked roads. PTCs, like Ophelia, will become more frequent under climate change conditions due to warmer sea surface temperatures and decreased vertical wind shear. Hence, hurricanes can reach northern latitudes more easily and have a higher chance of making landfall in Co. Cork. This thesis assesses the risk perception towards natural hazards (NHs) and the perception of the risk communication of hurricane Ophelia by the citizens of Co. Cork and suggests improvements in communication based on the people’s perception. This was achieved by conducting a standardised survey to analyse the perception. The risk communication chain, its content and media involved were evaluated with interviews with professionals involved in risk management in Ireland. Improvement suggestions were extracted of the survey and the expert interviews as well and have been ranked by the participating experts according to their importance. The people of Co. Cork are not overly concerned about being affected by NHs. The three hazards they feel threatened by most, after Ophelia hit the country, are storms, river floodings and hurricanes. Before Ophelia made landfall, they only ranked hurricanes in the 8th place (out of 8). Ergo, after experiencing Ophelia people are much more aware of hurricane risk in Ireland. People were very satisfied with the information they received during Ophelia. The improvements they wished for are: 1) information on how to deal with and how to prepare for impacts of the storm, 2) the impacts that can be expected locally and 3) information where to go to in case of severe impact to property. These are mostly in line with the improvements the experts ranked as most important for Cork. Experts voted the suggestion to include information on behavioural advice into risk communication before the NH hits and advice on how to organise for impacts afterwards as their number one priority. Their second rank is to have education and training for the citizens in Cork. On third place they voted for a change to impact forecasting. Even there are no central buildings or shelters available in Co. Cork, this improvement suggestion was only voted on rank 13 by the experts (out of 14). Having a participatory approach in risk communication can overcome the discrepancies between the wishes of the population and the ones of the experts and would lead to a better understanding of all stakeholders involved in risk communication and can reduce vulnerability of the people in Co. Cork to the impacts of NHs. The implementation of these activities would be in line with best practice examples and would support the guidelines of the Irish Framework for Major Emergency Management.
Die Rückversicherungsbranche steht auch weiterhin vor großen Herausforderun-gen. So war das Jahr 2022 für die Rückversicherung neben der fortdauernden Corona-Pandemie und Naturkatastrophen-Schäden auch durch den Ukraine-Krieg, die Energiekrise und die Inflation geprägt.
Die Kölner Forschungsstelle Rückversicherung analysiert die aktuellen Entwick-lungen des Rückversicherungsmarktes und begleitet diese gegebenenfalls durch Forschungsprojekte. Dabei verbindet die Forschungsstelle RV ihre Forschungs-aktivitäten mit der Rückversicherungspraxis. Hiermit und mit Hilfe der Durchfüh-rung des jährlichen Kölner Rückversicherungs-Symposiums und der Jahrestagung des Förderkreises Rückversicherung wird ein bidirektionaler Wissenstransfer zwi-schen Theorie und Praxis betrieben. Im Jahr 2022 musste das Kölner Rückversicherungs-Symposiums leider aufgrund Covid-19 ausfallen.
Die Inhalte dieser beiden wissenschaftlichen Veranstaltungen sowie die bearbei-teten Forschungsprojekte fließen in die Lehre an dem Institut für Versicherungs-wesen ein und komplettieren so die praxisorientierte Ausbildung in dem Bereich der Rückversicherung.
In der Kölner Forschungsstelle Rückversicherung sind derzeit acht Mitarbeiter*innen beschäftigt und zudem vier Professoren tätig. Dabei werden sämtliche Personal-, Sach- und Reisekosten vollständig aus Drittmitteln des För-derkreises Rückversicherung finanziert. Zu diesen Finanzierungen gehört unter anderem die Promotion von Herrn Frank Cremer.
Die im Rahmen der 14. Jahrestagung 2021 des Förderkreises Rückversicherung beschlossene finanzielle Unterstützung des gemeinnützigen Vereins „Hilfe für Guinea e.V.“ wurde in 2022 fortgesetzt. Durch die jährliche Spende an dieses Projekt erfüllt die Kölner Forschungsstelle Rückversicherung das für einen offiziellen Forschungsschwerpunkt geforderte Kriterium „Gesellschaftliches Engagement“. Die Spende kommt dem Projekt La Lumière Scolaire zugute. Dieses Projekt finanziert den Schulbau und den laufenden Schulbetrieb für Kinder von Körperbehinderten und Obdachlosen in Guinea.
Die Kölner Forschungsstelle Rückversicherung ist von der TH Köln als offizieller Forschungsschwerpunkt akkreditiert.
The challenges facing the reinsurance industry remain considerable. For the reinsurance sector, 2022 was marked not only by the ongoing coronavirus pandemic and claims due to natural disasters but also by the war in Ukraine, the energy crisis and inflation.
The Cologne Research Centre for Reinsurance analyses the latest developments in the reinsurance market and, where appropriate, monitors these through research projects. In the process, the Research Centre for Reinsurance links its research activities with practices in the reinsurance sector. Hereby, and facilitated through organisation of the annual Cologne Reinsurance Symposium and the Annual Meeting of the Sponsoring Group Reinsurance [Förderkreis Rückversicherung], a bi-directional transfer of knowledge between theory and practice is pursued. Unfortunately the Cologne Reinsurance Symposium for 2022 had to be cancelled due to COVID-19.
The content of these two scientific events, as well as the completed research projects, are incorporated into scholarship and instruction at the Institute of Insurance Studies, rounding out practice-oriented training in the field of reinsurance.
There are eight researchers and four professors currently on the staff of the Cologne Research Centre for Reinsurance. Thereby, all material and personnel costs are fully financed by third-party funds provided by the Sponsoring Group Reinsurance. This funding helped facilitate the doctorate of Mr Frank Cremer, among other things.
At the 14th Annual Meeting of the Sponsoring Group Reinsurance held in 2021, the decision was taken to continue to provide financial support to the non-profit organisation ‘Hilfe für Guinea e.V.’ Through its annual donation to this project, the Cologne Research Centre for Reinsurance fulfils the criterion of ‘social commitment’ required of an official research focus. The donation will benefit the La Lumière Scolaire project. This project finances the construction and operation of schools for the children of disabled and homeless people in Guinea.

Diese Ausarbeitung basiert auf der Bachelorarbeit von Herrn Andreas Matern, welcher von Juli 2022 bis Oktober 2022 von Frau Prof. Dr. Monika Engelen betreut wurde. Das Ziel der Bachelorarbeit war es, den sinnvollen Einsatz von Chatbots im Marketing herauszuarbeiten. Hierzu wurden elf Chatbot-Agenturen mittels qualitativer Inhaltsanalyse nach Mayring untersucht. Darüber hinaus wurden mögliche Anwendungsbeispiele anhand von vier Fallstudien entlang der Customer Journey analysiert.
Aim: European cities are facing heighten hydrological risks as a result of climate change at the same time as ecological degradation has reduced the environmental capacity to absorb and regulate such fluctuations. Climate forecasts predict more intense convective rainfall and winter flood events in the Wupper Basin in Germany, against a background trend of reduced mean rainfall during the summer months. On 14 July 2021 intense convective rainfall fell at points across Western Germany and led to flash floods in the Wupper Basin, many sites were inundated and the Wupper and Dhünn rivers rose to new record highs. Green-blue infrastructure offers strategies to reduce the impacts of hazards at the same time as providing a range of co-benefits. A study was undertaken to find which green-blue interventions will be most effective at reducing the impacts of hydrometeorological hazards for a study area in the west of the Wupper basin. Furthermore, as landscape features are highly influential in hydrology, the study sought to establish which sites within the landscape can provide maximum results from green-blue interventions, with a minimum of change to current land uses.
Region: Europe, peri-urban and rural, undulating, low mountainous landscapes
Methods: Literature findings on observed and projected climate data are summarised and long-term rainfall data from the study area is analysed to confirm rainfall trends. A state-of-the-art review is conducted and summarised to form a toolbox of potential interventions. The most recent hazardous hydrometeorological event is analysed to inform the locational priorities of potential interventions. Landscape features that have the most influence on basin hydrology are identified from the literature. These sites are paired with green-blue interventions that are shown to have the highest potential impact on interception, infiltration, runoff and flooding. A series of spatial analyses are carried out to produce maps detailing location and intervention with high potential to reduce the impact of hydrometeorological hazards in the study area. All of the evidence gathered from the literature analysis is combined in an implementation guide for green-blue interventions in the Wupper Basin.
Results: The hazards caused by the hydrometeorological extremes of flooding and drought are addressed or minimised through the green-blue interventions that increase interception and infiltration and reduce runoff and flooding. Priority locations are identified as the riparian zone with slope ≤15%, hilltop, lower slope and toe slope, all locations with a slope ≥30% and areas with a high topographic wetness index (TWI). A series of spatial analyses were carried out and suggestions made including potential locations for retention or detention areas and ponds, sites for revegetation and potential locations for implementation of shelterbelts/hedgerows, buffer strips, conservation tillage or strip tillage, reduced mowing intensity or frequency and biochar additions. An implementation guide is created that provides a summary of the highest potential green-blue interventions and landscape locations, and a description of the mechanisms involved in addressing the hydrometeorological hazards.
Keywords: Green-blue interventions, hydrometeorological hazard reduction, Wupper Basin hydrology
The demand for explainable and transparent models increases with the continued success of reinforcement learning. In this article, we explore the potential of generating shallow decision trees (DTs) as simple and transparent surrogate models for opaque deep reinforcement learning (DRL) agents. We investigate three algorithms for generating training data for axis-parallel and oblique DTs with the help of DRL agents (“oracles”) and evaluate these methods on classic control problems from OpenAI Gym. The results show that one of our newly developed algorithms, the iterative training, outperforms traditional sampling algorithms, resulting in well-performing DTs that often even surpass the oracle from which they were trained. Even higher dimensional problems can be solved with surprisingly shallow DTs. We discuss the advantages and disadvantages of different sampling methods and insights into the decision-making process made possible by the transparent nature of DTs. Our work contributes to the development of not only powerful but also explainable RL agents and highlights the potential of DTs as a simple and effective alternative to complex DRL models.
Multifocal intraocular lenses incorporate a variety of design considerations, including dimensioning of the base monofocal shape and the diffraction grating. While studying three different lens models, we present a practical approach for mathematical modelling and evaluation of these geometries. Contrary to typical lens measurement methods, non-contact measurements were performed on the Alcon SN6AD1, HumanOptics MS 612 DAY and the AMO ZMA00 lenses using a confocal microscope. Subsequent data processing includes centering, tilting correction, filtering and an algorithmic decomposition into a conic and polynomial part and the diffraction grating. Lastly, evaluation of fitting parameters and grating shape is done to allow for inferences about further optical properties. Results and analysis show the confocal microscope to be a suitable imaging method for lens measurements. The processing of this data enables the reconstruction of the annular diffraction grating over the complete lens diameter. Apodization, near addition and diffraction efficiency characteristics are found utilizing the grating shape. Additionally, near-optical axis curvature, asphericity and higher order polynomials are identified qualitatively from the reconstruction of the monofocal base form. Derived properties also include the lens optical base and addition power. By making use of the surface geometries, as well as the lens’ material and thickness, a full lens model can be created for further studies. In summary, our analytical approach enables the insight to various intraocular lens design decisions. Furthermore, this procedure is suitable for lens model creation for research and simulation.
Für den erfolgreichen Ausbau der Elektromobilität nimmt die Nutzerakzeptanz eine entscheidende Rolle ein. Neben den Anschaffungskosten, Wirkungsgraden und Reichweiten fällt vor allem der Komfort des Ladevorgangs als entscheidende Einflussgröße ins Gewicht. Zum aktuellen Zeitpunkt beeinflussen eine Reihe an negativen Faktoren (z.B. Ladeinfrastruktur, Preisintransparenz und vielfältige Bezahlsysteme) den Ladekomfort und halten potenzielle Käufer eines Elektroautos letztlich vom Erwerb ab. Im Rahmen dieser Arbeit soll aus unmittelbarer Sicht der Nutzer:innen der derzeitige Stand der Ladeinfrastruktur und das aktuelle Nutzerverhalten sowie potenzielle Erfolgsfaktoren herausgearbeitet werden. Weiterhin werden verschiedene Lösungsvorschläge erprobt, die den Ladekomfort an öffentlichen Ladesäulen erhöhen soll. Dazu wird eine zweitstufige Online-Studie im Zuge des vom Bundesministerium für Wirtschaft und Klimaschutz geförderten Transformationsnetzwerk „TrendAuto2030plus“ koordiniert und von Studierenden des Master-Kurses „Technologie und Innovationsmanagement“ an der TH Köln durchgeführt. Gemessen an der bisherigen Nachfrage ist die Ladeinfrastruktur in Deutschland besser als ihr Ruf. Ein deutliches Bild der Unzufriedenheit zeigt sich derweil in Bezug auf die aktuell vorherrschende Preisintransparenz an öffentlichen Ladestationen. Die Vielfalt der Tarifmodelle und Bezahlsysteme erfordern eine großen Strukturierungs- und Informationsbedarf. Es werden Systeme der Preisanzeige gefragt sein, die der Vielfalt und Dynamik der unterschiedlichen Bezahl- und Tarifmodelle Rechnung tragen und diese transparent und nutzerfreundlich ausweisen.
This work is intended to make it easier for companies to increase their dynamic capabilities in agile market environments. For this purpose, the areas of a company that are relevant for dynamic capabili-ties are presented and weighted in a clear model. In addition, a direction is proposed for the expansion of dynamic capabilities regarding the order in which the areas of a company should be considered.
The work is based on a literature analysis that provides an approach to bring together the various re-search approaches. For this purpose, the state of research on the topic of dynamic capabilities was developed using an extensive methodology and related to the value chain model according to Porter and the St. Gallen management model, two models valued in practice, in order to identify the relevant areas for dynamic capabilities. The research relates to a broad publication period and a large number of papers. In this way, the various development steps of Dynamic Capabilities over the years could be presented by means of a systematic analysis in which different approaches are summarized. Further-more, these areas were compared and evaluated in terms of relevance in three analysis steps. The findings of the analysis of many individual approaches were summarized in a new model and consider the entire corporate function.
Dieser Beitrag fasst den bisherigen Entwicklungsstand der Dynamic Capabilitiy Forschung systematisch zusammen und schafft ein Konzept zur Übertragbarkeit der Forschungsergebnisse in die praktische Anwendung. Es werden die für die dynamischen Fähigkeiten relevanten Bereiche eines Unternehmens in einem übersichtlichen Modell dargestellt und gewichtet. Darüber hinaus wird eine Richtung für den Ausbau der dynamischen Fähigkeiten vorgeschlagen, in welcher Reihenfolge die Bereiche eines Unternehmens berücksichtigt werden sollten.
Die Arbeit basiert auf einer systematischen Literaturanalyse, die einen Ansatz bietet, die verschiede-nen Forschungsansätze zusammenzuführen. Es wurden die Forschungsergebnisse zu Dynamic Cap-abilities mit dem Wertschöpfungskettenmodell nach Porter und dem St. Galler Managementmodell, zwei in der Praxis etablierte Ansätze, verknüpft, um die relevanten Handlungsfelder für Dynamic Cap-abilities zu identifizieren. Die Untersuchung bezieht sich auf einen breiten Publikationszeitraum und eine große Anzahl relevanter Veröffentlichungen. Durch die übergeordnete Betrachtungsanalyse wird der Beitrag den vielfältigen Forschungsströmungen zu Dynamic Capabilities gerecht. Auf dieser Basis wurde ein funktionaler Gestaltungsansatz für die Praxis entwickelt.
Kategorisierung und Bewertung plattformübergreifender Ansätze für die Auswahl eines Frameworks
(2023)
Die plattformübergreifende Entwicklung ist eine populäre Art der Anwendungsentwicklung, die in der Forschung und Industrie immer weiter an Relevanz gewinnt. Dabei wird eine Codebasis geschrieben, die auf mehreren Betriebssystemen lauffähig ist. Das Ziel dieses Ansatzes ist es unter anderem, die Zeit- und Kosteneffizienz zu optimieren. Es gibt verschiedene Ansätze der plattformübergreifenden Entwicklung. Die einzelnen Frameworks lassen sich wiederum in diese Ansätze einteilen. Durch die steigende Akzeptanz dieser Art der Entwicklung herrscht eine zu große Auswahl an Frameworks, von denen jedes eigene Stärken und Schwächen aufweist. Dies ist ein Problem, da Entwickelnde keine Übersicht und Einordnung der Frameworks für ihre individuellen Bedürfnisse haben. Um diesem Problem entgegen zu wirken, wird in dieser Arbeit ein Verfahren entwickelt, mit dem das passende Framework für die Rahmenbedingungen des jeweiligen Projekts ermittelt werden kann. Dazu werden die Frameworks Kotlin Multiplatform, Flutter, React Native und Vue.js, das zur Umsetzung einer PWA genutzt wird, für eine mobile Anwendung getestet, die auf Android und iOS Geräten laufen soll. Zusätzlich werden 44 Kriterien ermittelt, anhand derer die Frameworks bewertet werden. Mit dem resultierenden Verfahren kann sowohl eine objektive, als auch eine subjektive Auswertung der Frameworks erfolgen, um eine geeignete Auswahl zu treffen.
Smartphones und die Nutzung von mobilen Anwendungen gewinnen aufgrund der stetig voranschreitenden Digitalisierung weiter an Relevanz. Im April 2022 lag die Zahl der genutzten mobilen Endgeräte bei knapp 6 Milliarden, wobei die Hersteller Apple
und Google einen Marktanteil von knapp 99 % einnehmen. Um als Entwickler eine möglichst große Zielgruppe anzusprechen, ist es daher wichtig, die eigene Anwendung auf möglichst vielen Plattformen zur Verfugung stellen zu können. Die native Entwicklung ist einer der am meist verbreitetste Entwicklungsansatz für mobile Anwendungen. Dort werden plattformspezifische Tools sowie native Programmiersprachen verwendet. Hierbei ergeben sich allerdings diverse Herausforderungen für Entwickler entlang des gesamten Entwicklungsprozesses. Neben der nativen Entwicklung existiert der Ansatz von Cross-Plattform. Hierbei handelt es sich um einen Sammelbegriff für verschiedene Ansätze, welche das Ziel verfolgen eine Anwendung durch die Nutzung einer einheitlichen Codebasis auf mehreren Plattformen zur Verfugung zu stellen. Einer dieser Unteransätze ist
Backend-Driven UI, worin die gesamte Anwendung innerhalb eines strukturierten Datenformats beschrieben und serverseitig verwaltet wird. Der Client kann diese Daten dann dynamisch anfragen und zur Laufzeit in native UI überführen. Das Konzept von Backend-Driven UI wird bereits durch Unternehmen wie Airbnb oder SiriusXM eingesetzt, ist hier allerdings stark auf anwendungsbezogene Prozesse zugeschnitten. Es bedarf daher eines Backend-Driven UI Frameworks, welches es Entwicklern ermöglichen soll, mobile Anwendungen, ohne anwendungsspezifische Einschränkungen plattformübergreifend zu entwickeln. Im Rahmen dieser Arbeit wurde daher zunächst eine plattformunabhängige und erweiterbare Architektur eines solchen Frameworks entwickelt und in Form eines ersten Prototyps auf ihre Umsetzbarkeit geprüft. Insgesamt stellt der Prototyp eine mögliche Umsetzung von Backend-Driven UI dar und ist in der Lage erste Anwendungsszenarien abzudecken. Es konnten dennoch Bereiche ermittelt werden, welche im Zuge zukünftiger Entwicklung ausgebaut werden können. Dazu zählt unter anderem das Umsetzen von serverseitig bestimmter Anwendungslogik sowie der Umgang mit Unterschieden im plattformspezifischen Funktionsumfang.
This study explores the potential of robust, strongly basic type I ion exchange resins—specifically, Amberlyst® A26 OH and Lewatit® K 6465—as catalysts for the aldol condensation of citral and acetone, yielding pseudoionone. Emphasis is placed on their long-term stability and commendable performance in continuous operational settings. The aldol reaction, which traditionally is carried out using aqueous sodium hydroxide as the catalyst, holds the potential for enhanced sustainability and reduced waste production through the use of basic ion exchange resins in heterogeneous catalysis. Density Functional Theory (DFT) calculations are employed to investigate catalyst deactivation mechanisms. The result of these calculations indicates that the active sites of Amberlyst® A26 OH are cleaved more easily than the active sites of Lewatit® K 6465. However, the experimental data show a gradual decline in catalytic activity for both resins. Batch experiments reveal Amberlyst® A26 OH’s active sites diminishing, while Lewatit® K 6465 maintains relative consistency. This points to distinct deactivation processes for each catalyst. The constant count of basic sites in Lewatit® K 6465 during the reaction suggests additional factors due to its unique polymer structure. This intriguing observation also highlights an exceptional temperature stability for Lewatit® K 6465 compared to Amberlyst® A26 OH, effectively surmounting one of the prominent challenges associated with the utilization of ion exchange resins in catalytic applications.
Die Forschungsarbeit untersucht den sich verhärtenden Rückversicherungsmarkt und die Relevanz von Captives für Industrieunternehmen. Angesichts von Marktveränderungen wie steigender Inflation, Währungsschwankungen und höheren Schadensbelastungen überdenken Unternehmen ihre Risikomanagementansätze. Captives, insbesondere für mittelständische Unternehmen, gewinnen an Bedeutung. Sie bieten direkten Zugang zum Rückversicherungsmarkt, Unabhängigkeit und flexible Gestaltungsmöglichkeiten. Trotz Vorteilen wie optimierten Deckungsstrukturen und Umgehung von Marktveränderungen existieren Herausforderungen, darunter Kapitalanforderungen und Betriebskosten. Der Trend zu neuen Captives im harten Rückversicherungsmarkt ist nicht eindeutig, aber sie bleiben eine innovative Lösung für das betriebliche Risikomanagement. Traditionelle Rückversicherer bleiben entscheidend für die Branchenstabilität.
Die IEA prognostiziert einen Anstieg des globalen Anteils erneuerbarer Energien am Energiemix von 22,8% in 2015 auf 38,1% in 2027, begleitet von verstärktem (Rück-) Versicherungsbedarf. Sechs Herausforderungen in der Rückversicherung erneuerbarer Energien werden skizziert, darunter komplexe Underwriting-Anforderungen, zunehmende Integration von ESG-Faktoren, Bewertung der Zeichnungspolitik der Zedenten, Mangel an Schadenerfahrung, Naturkatastrophenexposition und die Anpassung von Rückversicherungsformen an die spezifischen Bedürfnisse. Die Zukunft erfordert den Aufbau von Expertise für erneuerbare Energien und eine ganzheitliche Bewertung von Schadensszenarien. Besonders im Offshore Wind Geschäft bleibt ein Druck auf Preise und Bedingungen bestehen.
Cyber-Risiken, vor allem in Form von Cyber-Kriegsführung und staatlich unterstützten Angriffen, stellen eine große Herausforderung dar. Im Kontext der Versicherung, sollen solche Risiken über Kriegsklausel ausgeschlossen werden. Derzeit gibt es unterschiedliche Herausforderungen wie fehlende klare rechtliche Regelungen, die Unsicherheiten für Versicherer und Versichert darstellen. Die Interviews mit Branchenvertretern zeigen unterschiedliche Meinungen darüber, wie die Versicherungswirtschaft Cyber-Kriegsrisiken wahrnimmt und damit umgeht. Trotz der sich ständig ändernden Natur dieser Bedrohungen besteht weiterhin Bedarf an Forschung und Datenerfassung, um eine gut durchdachte Versicherungslösung zu entwickeln.
Due to their unpredictable nature and sweeping impacts make cyber risks, including cyber warfare and state-sponsored cyber-attacks, present a considerable challenge to many areas of our daily lives. In today’s connected world, the threat of cyber risk is omnipresent. Cyber warfare and state-sponsored cyber-attacks are of particular concern, as they are initiated or supported by governments or state actors. Often, the purpose of such attacks is to compromise critical infrastructure, government systems, businesses, or citizens’ privacy. The impacts can be devastating. They range from financial losses for businesses to theft of intellectual property, disruptions of public order and threats to national security.
Learning more about the ways in which market participants in the reinsurance market interact based on the logic of a game requires a realisation that the main research that exists is in the mathematical/actuarial direction in which mathematicians deal with ‘optimal reinsurance contracts’. In this connection, negotiations between cedants and reinsurers are viewed in different ways, but always as a strategic game.
Das Projekt „IDiT – INCLUDING.DIGITAL.TWINS. Inklusion durch digitale Medien in der beruflichen Bildung“ erforscht, wie Rehabilitand:innen und Auszubildende digitale Expertise und mediale Kompetenzen erwerben können, die für einen erfolgreichen beruflichen (Wieder-)Einstieg unabdinglich sind. Die Integration medienpädagogischer Kompetenzen in Aus- und Fortbildung Lehrender wird bereits geraume Zeit diskutiert und erforscht (vgl. Jahrbuch Medienpädagogik 9, 2012). Dabei lag der Fokus zunächst auf der allgemeinen, schulischen Bildung, mittlerweile gibt es jedoch auch für die berufliche Ausbildung entsprechende Beiträge (vgl. Krämer et al. 2012). Die Sicht der Lehrenden in der beruflichen Ausbildung und Rehabilitation auf medienpädagogische Kompetenzen und Kompetenzmodelle wird bei theoretischen Überlegungen hierzu jedoch nur selten berücksichtigt. Das Projekt IDiT setzt dort an und arbeitet ein bedarfsorientiertes Konzept zur Vermittlung von medienpädagogischer Kompetenz an Lehrende in der beruflichen Rehabilitation aus. Denn für die Vermittlung medialer Kompetenzen braucht es medienkompetente und medienpädagogisch kompetente Lehrende. Doch diese Kompetenzen, in der Form in der sie heute relevant sind1, waren meist kein Bestandteil der professionellen Ausbildung von Lehrpersonen der beruflichen Ausbildung und Rehabilitation.
Die hier vorgeführte Studie erhebt, welche Bedarfe Lehrende in der Berufsausbildung und beruflichen Rehabilitation haben, um digitale Expertise und mediale Kompetenzen an Auszubildende und RehabilitandInnen vermitteln, fördern und stärken zu können.
A novel approach to manufacture components with integrated conductor paths involves embedding and sintering an isotropic conductive adhesive (ICA) during fused filament fabrication (FFF). However, the molten plastic is deposited directly onto the adhesive path which causes an inhomogeneous displacement of the uncured ICA. This paper presents a 3D printing strategy to achieve a homogeneous cross-section of the conductor path. The approach involves embedding the ICA into a printed groove and sealing it with a wide extruded plastic strand. Three parameter studies are conducted to obtain a consistent cavity for uniform formation of the ICA path. Specimens made of polylactic acid (PLA) with embedded ICA paths are printed and evaluated. The optimal parameters include a groove printed with a layer height of 0.1 mm, depth of 0.4 mm, and sealed with a PLA strand of 700 µm diameter. This resulted in a conductor path with a homogeneous cross-section, measuring 660 µm ± 22 µm in width (relative standard deviation: 3.3%) and a cross-sectional area of 0.108 mm2 ± 0.008 mm2 (relative standard deviation 7.2%). This is the first study to demonstrate the successful implementation of a printing strategy for embedding conductive traces with a homogeneous cross-sectional area in FFF 3D printing.

To date, the establishment of high-titer stable viral packaging cells (VPCs) at large scale for gene therapeutic applications is very time- and cost-intensive. Here we report the establishment of three human suspension 293-F-derived ecotropic MLV-based VPCs. The classic stable transfection of an EGFP-expressing transfer vector resulted in a polyclonal VPC pool that facilitated cultivation in shake flasks of 100 mL volumes and yielded high functional titers of more than 1 × 106 transducing units/mL (TU/mL). When the transfer vector was flanked by transposon terminal inverted repeats (TIRs) and upon co-transfection of a plasmid encoding for the transposase, productivities could be slightly elevated to more than 3 × 106 TU/mL. In contrast and using mRNA encoding for the transposase, as a proof of concept, productivities were drastically improved by more than ten-fold exceeding 5 × 107 TU/mL. In addition, these VPC pools were generated within only 3 weeks. The production volume was successfully scaled up to 500 mL employing a stirred-tank bioreactor (STR). We anticipate that the stable transposition of transfer vectors employing transposase transcripts will be of utility for the future establishment of high-yield VPCs producing pseudotype vector particles with a broader host tropism on a large scale.
