CSR in der Messemarkenführung - Modellansatz zur Integration einer CSR Strategie in die identitätsbasierte Markenführung von Messeunternehmensmarken
Get PDFDie vorliegende Bachelorarbeit geht der Fragestellung nach, wie eine CSR Strategie in die identitätsbasierte Markenführung von Messeunternehmensmarken integriert werden kann. Dafür wurde insbesondere die Bildung und Gestaltung der Markenidentität betrachtet.
Um die Markenidentität einer Messedachmarke und gesellschaftliche Verantwortung zu verbinden und die Kontaktpunkte und Integrationsmöglichkeiten aufzuzeigen, wurden das Modell einer verantwortungsvollen Markenführung von Schmidt 2019 sowie das Gesamtmodell der Messedachmarkenidentität von Jung 2010 verwendet und inhaltlich sowie visuell miteinander verbunden.
Das daraus abgeleitete Modell bietet einen Ansatz der Integration von CSR Strategien in die identitätsbasierte Markenführung von Messeunternehmen. Grundlegend ist, dass Merkmale gesellschaftlicher Verantwortung Teil des gesamten Prozesses der Identitätserstellung sind und daher im Kern der Identität ansetzen sollten
Intermediate Cluster Disinfection: Which Disinfection Solution Is Most Effective on Milking Liners? A Comparison of Microorganism Reduction on Liner Inner Surfaces Using Quantitative Swab Sampling Technique
Get PDFDuring machine milking, pathogenic microorganisms can be transmitted from cow to cow through liners. Therefore, in Germany, a spray method for the intermediate disinfection of the milking cluster is often used for prevention. This method of cluster disinfection is easy to perform, requires little time and no extra materials, and the disinfection solution is safe from outside contamination in the spray bottle. Since no data on a systematic efficacy trial are available, the aim of this study was to determine the microbial reduction effect of intermediate disinfection. Therefore, laboratory and field trials were conducted. In both trials, two sprays of 0.85 mL per burst of different disinfectant solutions were sprayed into the contaminated liners. For sampling, a quantitative swabbing method using a modified wet–dry swab (WDS) technique based on DIN 10113-1: 1997-07 was applied. Thus, the effectiveness of disinfectants based on Peracetic Acid, Hydrogen Peroxide and Plasma-Activated Buffered Solution (PABS) was compared. In the laboratory trial, the inner surfaces of liners were contaminated with pure cultures of Escherichia (E.) coli, Staphylococcus (S.) aureus, Streptococcus (Sc.) uberis and Sc. agalactiae. The disinfection of the contaminated liners with the disinfectants resulted in a significant reduction in bacteria with values averaging 1 log for E. coli, 0.7 log for S. aureus, 0.7 log for Sc. uberis and 0.8 log for Sc. agalactiae. The highest reduction was obtained for contamination with E. coli (1.3 log) and Sc. uberis (0.8 log) when PABS was applied and for contamination with S. aureus (1.1 log) and Sc. agalactiae (1 log) when Peracetic Acid Solution (PAS) was used. Treatment with sterile water only led to an average reduction of 0.4 log. In the field trial, after the milking of 575 cows, the liners were disinfected and the total microorganism count from the liner surface was performed. The reduction was measured against an untreated liner within the cluster. Although a reduction in microorganisms was achieved in the field trial, it was not significant. When using PAS, a log reduction of 0.3 was achieved; when using PABS, a log reduction of 0.2 was obtained. The difference between the two disinfection methods was also not significant. Treatment with sterile water only led to a reduction of 0.1 log. The results show that spray disinfection under these circumstances does result in a reduction in the bacteria on the milking liner surface, but for effective disinfection a higher reduction would be preferred
A comparative Study of Deep Generative Models for Image Generation
Get PDFIn the last years generative models have gained large public attention due to their high level of quality in generated images. In short, generative models learn a distribution from a finite number of samples and are able then to generate infinite other samples. This can be applied to image data. In the past generative models have not been able to generate realistic images, but nowadays the results are almost indistinguishable from real images.
This work provides a comparative study of three generative models: Variational Autoencoder (VAE), Generative Adversarial Network (GAN) and Diffusion Models (DM). The goal is not to provide a definitive ranking indicating which one of them is the best, but to qualitatively and where possible quantitively decide which model is good with respect to a given criterion. Such criteria include realism, generalization and diversity, sampling, training difficulty, parameter efficiency, interpolating and inpainting capabilities, semantic editing as well as implementation difficulty. After a brief introduction of how each model works on the inside, they are compared against each other. The provided images help to see the differences among the models with respect to each criterion.
To give a short outlook on the results of the comparison of the three models, DMs generate most realistic images. They seem to generalize best and have a high variation among the generated images. However, they are based on an iterative process, which makes them the slowest of the three models in terms of sample generation time. On the other hand, GANs and VAEs generate their samples using one single forward-pass. The images generated by GANs are comparable to the DM and the images from VAEs are blurry, which makes them less desirable in comparison to GANs or DMs. However, both the VAE and the GAN, stand out from the DMs with respect to the interpolations and semantic editing, as they have a latent space, which makes space-walks possible and the changes are not as chaotic as in the case of DMs. Furthermore, concept-vectors can be found, which transform a given image along a given feature while leaving other features and structures mostly unchanged, which is difficult to archive with DMs

Die Potentiale der Form – Versuch einer phänomenologischen Designtheorie der Formen oder ob das Formendenken entgrenzt werden kann.
Get PDFDiese Arbeit thematisiert die unausgeschöpften Potentiale der von Designer*innen erzeugten Formen. Um zu klären, welche Wichtigkeit der Formfindung innerhalb des gestalterischen Prozesses zukommt, wird die Form mit anderen Parametern der Gestaltung verglichen. Es wird untersucht, welche Wirkungen die Formen auf Menschen haben können, die mit ihnen interagieren wollen oder müssen. Auf der Suche nach Möglichkeiten, die so ermittelten Potentiale freizuschalten, wird der bisher begrenzende Rahmen betrachtet. In einem phänomenologischen Versuch wird geprüft, welche Mannigfaltigkeit von dem generativen Prozess einer künstlichen Intelligenz vorgeschlagen werden kann. Das Ergebnis sind verschobene Grenzen, die zahlreiche Felder der Formausprägung zu einem Größeren erschließen. Eine absolute Entgrenzung des Formendenkens muss derweil scheitern
Referring physicians' intention to use hospital report cards for hospital referral purposes in the presence or absence of patient-reported outcomes: a randomized trial
Get PDFPurpose: This study aims to determine the intention to use hospital report cards (HRCs) for hospital referral purposes in the presence or absence of patient-reported outcomes (PROs) as well as to explore the relevance of publicly available hospital performance information from the perspective of referring physicians.
Methods: We identified the most relevant information for hospital referral purposes based on a literature review and qualitative research. Primary survey data were collected (May–June 2021) on a sample of 591 referring orthopedists in Germany and analyzed using structural equation modeling. Participating orthopedists were recruited using a sequential mixed-mode strategy and randomly allocated to work with HRCs in the presence (intervention) or absence (control) of PROs.
Results: Overall, 420 orthopedists (mean age 53.48, SD 8.04) were included in the analysis. The presence of PROs on HRCs was not associated with an increased intention to use HRCs (p = 0.316). Performance expectancy was shown to be the most important determinant for using HRCs (path coefficient: 0.387, p < .001). However, referring physicians have doubts as to whether HRCs can help them. We identified “complication rate” and “the number of cases treated” as most important for the hospital referral decision making; PROs were rated slightly less important.
Conclusions: This study underpins the purpose of HRCs, namely to support referring physicians in searching for a hospital. Nevertheless, only a minority would support the use of HRCs for the next hospital search in its current form. We showed that presenting relevant information on HRCs did not increase their use intention
Sexuality and sexual violence: A qualitative study exploring the perspectives of sexuality educators and sexual violence professionals
Get PDFThere has been an increase in discussion concerning the integration of sexuality education and the prevention of sexual violence. Furthermore, this is a concern at the level of different pedagogical professions in Germany, since sexuality education and sexual violence prevention have developed as largely separate fields. Both sexuality educators and sexual violence professionals work with a broad target group to prevent sexual violence, including children, young people, as well as parents and professionals working in social work or education. They collaborate at times, but they also engage in debates about their respective pedagogical approaches. Based on group discussions with 12 teams specializing in the two fields, this article analyzes how their tacitly shared knowledge (collective orientation) underpins their different pedagogical strategies. This should be considered to improve their long-term inter-professional cooperation
