    Verpackungsgestaltung und ihre Wirkung auf die Wahrnehmung von Nachhaltigkeit

    Full text link
    Die Verpackungsgestaltung spielt eine zentrale Rolle in der Wahrnehmung von Nachhaltigkeit durch Konsumenten. Diese Arbeit untersucht, wie verschiedene Verpackungsdesigns, insbesondere Farben und Materialien, die Nachhaltigkeitswahrnehmung beeinflussen. Eine systematische Literaturrecherche zeigt, dass Verbraucher Verpackungsmaterialien unterschiedlich bewerten: Glas und Papier werden häufig als nachhaltiger wahrgenommen als Plastik, obwohl deren tatsächliche Umweltbilanz oft schlechter ist. Farben wie Grün und Braun verstärken Nachhaltigkeitsassoziationen, während grelle Farben oder glänzende Oberflächen eher negativ wahrgenommen werden. Darüber hinaus zeigen die Ergebnisse, dass Konsumentensegmente unterschiedlich auf Verpackungsgestaltung reagieren. Gebildete Konsumenten mit höherer Kaufkraft bevorzugen nachhaltige Verpackungen, während preisbewusste Konsumenten eher funktionale und günstige Alternativen wählen. Transparente Labels und Umweltzertifikate können dabei helfen, nachhaltige Verpackungen glaubwürdiger zu machen und einer Verbrauchertäuschung entgegenzuwirken. Trotz positiver Nachhaltigkeitswahrnehmung bestehen Herausforderungen: Die wahrgenommene geringere Gebrauchstauglichkeit und höhere Preise nachhaltiger Verpackungen können Kaufentscheidungen negativ beeinflussen. Unternehmen sollten daher klare Kommunikationsstrategien und visuelle Designelemente kombinieren, um sowohl Nachhaltigkeit als auch Funktionalität hervorzuheben. Die Arbeit zeigt, dass nachhaltige Verpackungen nicht nur eine ökologische, sondern auch eine wirtschaftliche Relevanz haben. Unternehmen können durch gezielte Gestaltungskonzepte das Konsumverhalten beeinflussen und sich im Wettbewerb differenzieren. Weitere Forschung ist notwendig, um Auswirkungen nachhaltiger Verpackungen auf Kaufentscheidungen empirisch zu validieren.Packaging design plays a central role in consumers' perception of sustainability. This study examines how different packaging designs, particularly colors and materials, influence the perception of sustainability. A systematic literature review reveals that consumers evaluate packaging materials differently: glass and paper are often perceived as more sustainable than plastic, even though their actual environmental footprint is often worse. Colors like green and brown enhance sustainability associations, while bright colors or glossy surfaces tend to be perceived more negatively. Furthermore, the findings show that consumer segments respond differently to packaging design. Educated consumers with higher purchasing power tend to prefer sustainable packaging, whereas price-conscious consumers opt for functional and more affordable alternatives. Transparent labels and environmental certifications can help make sustainable packaging more credible and counteract consumer deception. Despite the positive perception of sustainability, challenges remain: the perceived lower usability and higher costs of sustainable packaging may negatively impact purchasing decisions. Therefore, companies should combine clear communication strategies with visual design elements to highlight both sustainability and functionality. The study demonstrates that sustainable packaging is not only ecologically but also economically relevant. Companies can influence consumer behavior through targeted design concepts and differentiate themselves in the competitive market. Further research is necessary to empirically validate the impact of sustainable packaging on purchasing decisions

    Welche Bedeutung kommt studentischer Partizipation in der Hochschullehre zu und wie wird sie im Hochschulalltag praktisch gelebt? Die Beiträge dieser ersten Ausgabe von Horizont Lehre widmen sich diesen Fragen aus unterschiedlichen Blickwinkeln. Sie beleuchten Potenziale von Partizipation, zeigen wie vielfältig sie ausgestaltet wird und skizzieren, in welche Richtungen weitergedacht werden kann. Dabei fließen sowohl theoretische und empirische Perspektiven als auch praktische Erfahrungen von Studierenden, Lehrenden und Hochschulmitarbeitenden ein. Die Ausgabe lädt dazu ein, etablierte Strukturen zu hinterfragen, Beteiligungsräume neu zu denken und gemeinsam weiter an einer partizipativen Hochschulkultur zu arbeiten.AlternativeReviewe

    Auswirkung von PRNGs auf den Particle Swarm Optimisation Algorithmus

    Full text link
    Diese Arbeit untersucht den Einfluss verschiedener Pseudozufallszahlengeneratoren (PRNGs) unterschiedlicher Qualitätsstufen auf die Partikelschwarmoptimierung (PSO). Die Ergebnisse zeigen, dass der Einfluss der PRNGs auf die PSO minimal ist, da selbst PRNGs geringerer Qualität bei der Optimierung von Benchmark-Funktionen zu vergleichbaren Ergebnissen führen können. Besonders bemerkenswert ist die Leistung des RANDU-Algorithmus, der oft als schlechter PRNG angesehen wird, jedoch vergleichbar gut mit den besten getesteten PRNGs abschneiden konnte.This study examines the impact of various pseudo-random number generators (PRNGs) of medium and high quality on particle swarm optimization (PSO). Results indicate, that the influence of these PRNGs on PSO performance is minimal. Particularly notable is the performance of the RANDU algorithm, often regarded as a poor PRNG, which performed comparably well to the best PRNGs tested

    Evaluation of the acceptability of ESIDA app, a smartphone-based clinical decision support application to improve infectious disease outbreak detection in Tanzania : clinician perspectives

    No full text
    Background: Epidemic-prone infectious diseases (EPIDs) such as dengue fever, coronavirus disease 2019 (COVID-19), leptospirosis, Marburg virus disease, measles and cholera, to name a few, place a significant burden on the Tanzanian population and health system. Clinicians working in primary health facilities (PHFs), such as dispensaries, health centres, and basic hospitals, play a vital role in detecting cases and outbreaks. However, they often face challenges, including insufficient knowledge of these diseases and a lack of supporting resources, including surveillance guidelines, standard case definitions, and, most importantly, access to confirmatory diagnostic tests. Although Tanzania reports outbreaks of infectious diseases almost every year, a significant number of cases go undetected and contribute to delayed response and recurrent outbreaks. Smartphone-based clinical diagnostic decision support systems (CDSS) have been proven to help bridge case detection gaps. The Epidemiological Surveillance for Infectious Diseases in Sub-Saharan Africa (ESIDA) project proposed developing the ESIDA app, a smartphone-based CDSS, to aid clinicians in the detection of EPIDs. Before developing the app, the ESIDA project evaluated its acceptability among clinicians, the primary target users. The aim was to gather insights to inform the app development, ensuring its design and features are relevant and applicable in Tanzania context. Methods: In-depth interviews were conducted with 21 clinicians, including medical doctors and clinical officers from public and private facilities in the Dar es Salaam region, which has reported frequent outbreaks of dengue and cholera. Data were collected and analyzed using the Unified Theory of Acceptance and Use of Technology (UTAUT) model. Result: Clinicians were positive about the proposed ESIDA app and intended to use it once it was available. The facilitators and barriers to acceptability focused on performance expectancy, effort expectancy, facilitating conditions and social influence. Expected benefits, ease of use, and government involvement emerged as facilitators of acceptability, while high internet costs, workload, time constraints, infrastructure gaps, and patient resistance were identified as potential barriers. Conclusion: The development of the ESIDA app should prioritize maximizing system performance and benefits. They must also be user-friendly and in line with social norms. The necessary infrastructure must be in place for effective implementation.PeerReviewe

    Calculating aircraft utilization

    Full text link
    Purpose – This project introduces the equation for calculating aircraft utilization and describes the parameters in the equation. Aim is also to point out differences in the notation used in the literature. --- Methodology – Aircraft utilization is explained based on the chapter "Design Evaluation / DOC" from the lecture notes "Aircraft Design" by Scholz (2015). Parameters that are kept generic in this reference, are mapped to reality with definitions from Thorbeck's DOC method from TU Berlin. Statistics of these parameters are obtained from a literature review. --- Findings – Aircraft utilization depends on two parameters. The block time supplement (taxi time plus turnaround time) and the annual operation time (annual potential operation time minus annual downtime). Downtime is caused by scheduled maintenance (A, B, C, D checks), unscheduled maintenance (repairs), and night curfew. Practical values are given. Taxi time (in and out) is together about 20 minutes. --- Research Limitations – Turnaround time can vary widely (both among aircraft types and airline philosophies). Delays can change turnaround and taxi time. Maintenance programs are structured differently among airlines, and night flying regulations are much different at different airports. Fixed values do not exist for these parameters. --- Practical Implications – It is essential for airlines to keep utilization high. The project shows how this can be achieved. --- Social Implications – Public and airline interests clash when discussing night curfew. Noise versus profit. Utilization is the parameter in question. --- Originality – A comparable report with a review of aircraft utilization was not found.NonPeerReviewe
