Integrating the two business areas promises synergistic added value that goes beyond their individual impact spectrums. While academic research has collectively advanced our understanding of brand management, research in business development is relatively underrepresented. As a management concept that is of great importance in the corporate world today, the relevance of business development cannot be denied in academia. Moreover, the interrelationship between business development and brand management has been widely neglected. Both business fields benefit from each other, suggesting an exigency for a deeper integration between the two. Towards that goal, this dissertation presents a comprehensive overview of the reciprocal relationship of business development and brand management that further stretches the academic knowledge space. Throughout the doctoral thesis, the author structures this interrelationship, enhances theory for both business areas and their integration, suggests managerial implications and identifies future research directions that require scholarly attention. The doctoral thesis aims to align business development and brand management theory and practice with the realities of the business world. In three research papers, this thesis develops an analysis of the reciprocal relationship of business development and brand management. For this purpose, a variety of methods ranging from a systematic literature review and qualitative work to empirical research employing structural equation modeling and experimental studies are applied. Theoretically, business development, innovation management, brand management and sustainability inform the frame of this work. Finally, this research project aims at contributing to (sustainable) business and brand growth.}, subject = {Marketing}, language = {en} } @misc{Schloth, type = {Master Thesis}, author = {Schloth, Sebastian}, title = {Beitrag zum Einfluss bogenf{\"o}rmiger Deichlinien mit innenliegenden vollkommenen Dichtungssystemen auf die Grundwasserstr{\"o}mung}, doi = {10.25643/bauhaus-universitaet.6518}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20240104-65186}, school = {Bauhaus-Universit{\"a}t Weimar}, pages = {274}, abstract = {Bei einigen bogenf{\"o}rmig verlaufenden Deichlinien ist es erforderlich, die Standsicherheit des Deiches mit Hilfe innenliegender vollkommener Dichtungssysteme zu verbessern.

Here, it is of great importance to use raw materials whose use does not compete with food production. In addition, the performance of the newly developed materials should be comparable to that of conventional products. Possible starting materials are lignin degradation products, such as vanillin and syringaldehyde, for which new synthesis routes to the desired products must be found and their properties determined. In this article, the first synthesis of two amine hardeners, starting with vanillin and syringaldehyde, using the Smiles rearrangement reaction is reported. The amine hardeners were mixed with bisphenol A diglycidyl ether, and the curing was compared to isophorone diamine, 4-4′-diaminodiphenyl sulfone, and 4-Aminonbenzylamine by means of differential scanning calorimetry. It was found that the two amines prepared are cold-curing. As TG-MS studies showed, the thermal stability of at least one of the polymers prepared with the potentially bio-based amines is comparable to that of the polymer prepared with isophorone diamine, and similar degradation products are formed during pyrolysis.}, subject = {Epoxide}, language = {en} } @article{PartschefeldTutalHalmansederetal., author = {Partschefeld, Stephan and Tutal, Adrian and Halmanseder, Thomas and Schneider, Jens and Osburg, Andrea}, title = {Investigations on Stability of Polycarboxylate Superplasticizers in Alkaline Activators for Geopolymer Binders}, series = {Materials}, volume = {2023}, journal = {Materials}, number = {Volume 16, issue 15, article 5369}, publisher = {MDPI}, address = {Basel}, doi = {10.3390/ma16155369}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20231026-64809}, pages = {1 -- 14}, abstract = {Calcined clays are interesting starting materials to be used as SCMs (supplementary cementitious materials) in cements or to be converted to geopolymers by activation with a high alkaline activator. The adjustment of the properties in the fresh state, especially regarding the consistency of these binders, is almost exclusively achieved by the addition of water, since commercially available superplasticizers seem to be ineffective in low-calcium geopolymer systems. The aim of this study was a systematic investigation of various PCE (polycarboxylate ester/ether) superplasticizers (methacrylate ester PCE: MPEG, isoprenol ether PCE: IPEG, methallyl ether PCE: HPEG) with respect to their stability in different alkaline activators (NaOH, KOH, sodium and potassium silicate solutions). The effectiveness of superplasticizers (SPs) in low-calcium geopolymer binders was verified by rheological tests. Size exclusion chromatography was used to investigate if structural degradation of the superplasticizers occurs. The investigated PCE superplasticizers showed a thickening effect in the low-calcium geopolymer system. Depending on the alkalinity of the activator solution, a degradation process was detected for all the PCEs investigated. The side chains of the PCEs are cleaved off the backbone by basic ester and ether hydrolysis. The highest degree of degradation was found in sodium and potassium silicate solutions. In alkaline hydroxide solutions, the degradation process increases with increasing alkalinity.}, subject = {Geopolymere}, language = {en} } @article{AlsaadSchaelteSchneeweissetal., author = {Alsaad, Hayder and Sch{\"a}lte, Gereon and Schneeweiß, Mario and Becher, Lia and Pollack, Moritz and Gena, Amayu Wakoya and Schweiker, Marcel and Hartmann, Maria and Voelker, Conrad and Rossaint, Rolf and Irrgang, Matthias}, title = {The Spread of Exhaled Air and Aerosols during Physical Exercise}, series = {Journal of Clinical Medicine}, volume = {2023}, journal = {Journal of Clinical Medicine}, number = {Volume 12, issue 4, article 1300}, publisher = {Basel}, address = {MDPI}, doi = {10.3390/jcm12041300}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20230208-49262}, pages = {20}, abstract = {Physical exercise demonstrates a special case of aerosol emission due to its associated elevated breathing rate. This can lead to a faster spread of airborne viruses and respiratory diseases. Therefore, this study investigates cross-infection risk during training. Twelve human subjects exercised on a cycle ergometer under three mask scenarios: no mask, surgical mask, and FFP2 mask. The emitted aerosols were measured in a grey room with a measurement setup equipped with an optical particle sensor. The spread of expired air was qualitatively and quantitatively assessed using schlieren imaging. Moreover, user satisfaction surveys were conducted to evaluate the comfort of wearing face masks during training. The results indicated that both surgical and FFP2 masks significantly reduced particles emission with a reduction efficiency of 87.1\% and 91.3\% of all particle sizes, respectively. However, compared to surgical masks, FFP2 masks provided a nearly tenfold greater reduction of the particle size range with long residence time in the air (0.3-0.5 μm). Furthermore, the investigated masks reduced exhalation spreading distances to less than 0.15 m and 0.1 m in the case of the surgical mask and FFP2 mask, respectively.

We analyse the way in which two German 'climate emergency municipalities' translate conflicts of post-fossil transformation into concrete political and planning strategies. Although more than 2,200 authorities around the world have already declared a climate emergency, research on the impact of these resolutions on the political orientation of municipalities is very limited. Our research focus is on the (potentially agonistic) treatment of conflicts in planning. We argue that in times of a socio-ecological crisis, success in conflict resolution cannot refer to appeasement and depoliticisation. Instead, we propose a framework of five criteria, based on critical theory on ecomodern strategies, planning processes and degrowth. Thus, this practice-related and explorative paper connects empirical insights from the German cities of Constance and Berlin with an innovative normative framework. The findings tell a complex story of an, at least partial, admission of the failure of previous climate mitigation strategies, a lack of social institutions of limits, an instrumental relation to nature and a disregard for social injustices. The paper discusses how municipalities, in the context of ongoing tensions over the post-fossil transformation in Germany, on the one hand hold on to business-as-usual approaches, but on the other hand also set political impulses for change.}, subject = {Stadtentwicklung}, language = {de} }
