TY - THES A1 - Aziz, Sk Tarik T1 - The Impact of Employee Job Satisfaction on Organization's Long-Term Performance N2 - The purpose of the study is to investigate the impact of employee job satisfaction on organizational long-term performance and focus on the key factors that increase satisfaction among employees. Previous research has mostly focused on short-term organizational outcomes, and there is limited evidence about the factors that enhance job satisfaction and ensure long-term performance of an organization. To fill this gap, qualitative research was conducted, and data was collected through semi-structured interviews, and the data was analyzed using MAXQDA software. The findings represent some of the factors that significantly increase job satisfaction, such as positive and supportive work environment, flexibility and autonomy at work, career growth and continuous learning opportunities, and fair compensation with meaningful recognition. The participants repeatedly highlighted these factors as a source of enhancing motivation, dedication, commitment, and employee performance. The study suggests that when organizations actively follow and implement these factors, it is more likely to increase employee satisfaction and satisfied employees improve productivity, achieve organizational goals, and increase a higher level of dedication, which ensures organizational long-term performance.

These nitrogen-containing pigments contribute to stress tolerance and have applications as natural colorants and food supplements due to their antioxidant properties. This study investigated the effect of high salt stress (200mM NaCl) on growth, physiological performance, betalain accumulation, pigment composition, and gene expression in six Amaranth accessions over a 14-day period of exposure. Phenotypic observations revealed visible stress symptoms, such as reduced growth and leaf senescence, whereas physiological parameters such as photosynthesis, stomatal conductance, transpiration, and internal CO2 concentration remain unaffected by salinity. Spectrophotometric quantification showed an increase in betalain concentrations after the 14-day testing period in all genotypes, salt treatment showed minor inconsistent effects. The total betalain concentration was quantified, the results per accession are for Ama 104 3.013 mg/100 g FW, Ama 124 2.944 mg/100 g FW, Ama 154 4.088 mg/100 g FW, Ama 157 4.735 mg/100 g FW, Ama 162 2.227 mg/100 g FW, Ama 169 18.248 mg/100 g FW. Characterization of betalains with HPLC-DAD-MS analysis confirmed the presence of amaranthine and isoamaranthine as the dominant betalain present in Amaranth leaves, which is consistent with the known betalain presence of grain amaranth species; no betaxanthins were detected. Gene expression analysis of CYP76AD2, DODA2, DODAα2, and SOS1 revealed no significant transcriptional induction under salt stress after the 14-day salt stress treatment. These results may suggest that betalain accumulation occurred due to normal developmental regulation rather than a salinity effect. However, analysis 24-48 after salt stress induction is recommended to conclude. The combined results reveal variation in pigment levels and salinity-stress response and demonstrate the resilience of grain amaranth to increased salinity exposure. The variation in pigment accumulation indicates the importance of selecting high-betalain accessions for industrial applications at an early stage. Future research should focus on early transcriptional levels and regulatory mechanisms to better understand stress response in the betalain pathway of these amaranth accessions. Y1 - 2025 ER - TY - THES A1 - Ustritski, Nikita T1 - Competitiveness of Green vs. Traditional Companies: A Comparative Study in the Automotive, Hospitality, and Fashion Industry N2 - This thesis compares short-term and long-term competitiveness between green and traditional companies in the automotive, hospitality, and fashion industries. Existing research rarely examines multiple industries together or evaluates competitiveness using both time perspectives, creating a clear research gap. The research question asks how green and traditional companies differ in financial performance, innovation, consumer trust, and regulatory responsiveness. The hypothesis proposes that green companies show lower short-term competitiveness, but higher long-term competitiveness than traditional firms. A qualitative comparative case study approach is applied using secondary data, including annual reports, sustainability disclosures, ESG ratings, and international regulatory frameworks. Six companies are analysed: Tesla and Toyota in the automotive sector, Hilton and Wyndham in hospitality, and Kering and H&M in fashion. Their competitiveness is assessed through a structured framework that distinguishes between immediate business outcomes and long-term strategic development. The findings show that traditional companies perform better in the short term due to efficient cost structures, established operating models, and stable supply chains. Green companies, however, achieve stronger long-term competitiveness by investing in innovation, transparency, and alignment with tightening regulatory and consumer expectations. Tesla, Hilton, and Kering demonstrate superior long-term performance, while Toyota, Wyndham, and H&M maintain advantages mainly in the short term. The results support the hypothesis and highlight sustainability as an important driver of long-term competitiveness. The study offers cross-industry insights for academics, managers, and policymakers and identifies opportunities for future research on sustainable business models.

Trotz der zunehmenden Bedeutung eines Betrieblichen Gesundheitsmanagements (BGM) existieren insbesondere an kleinen und mittleren Regionalflughäfen bislang wenig systematische und arbeitsplatzspezifische Gesundheitskonzepte. Die Anforderungen an Gesundheit und Einsatzfähigkeit der Flughafenfeuerwehren werden zudem durch die Vorgaben der Europäischen Agentur für Flugsicherheit (EASA) maßgeblich mitbestimmt. Ziel dieser Arbeit war es, das Belastungs- und Bedarfsprofil der Flughafenfeuerwehr am Airport Weeze zu erfassen und darauf basierend ein ganzheitliches und EASA-konformes Maßnahmenkonzept zur Gesundheitsförderung und Erhaltung der Einsatzfähigkeit zu entwickeln. Methode: Die Untersuchungen erfolgten im Rahmen eines Mixed-Methods-Designs. Insgesamt 28 der 37 angestellten Einsatzkräfte wurden mittels eines teilstandardisierten Fragebogens zu physischen und psychischen Belastungsfaktoren, Trainings- und Erholungsverhalten sowie der Akzeptanz und den Wünschen zu gesundheitsbezogenen Maßnahmen befragt. Ergänzend wurde eine systematische Dokumenten- und Umfeldanalyse sowie eine SWOT (Strengths, Weaknesses, Opportunities, Threats)-Analyse durchgeführt, um strukturelle Ressourcen, Barrieren und Entwicklungspotenziale zu identifizieren. Ergebnisse: Die Auswertung zeigt eine heterogene Alters- und Diensterfahrungsstruktur. Belastungsschwerpunkte wurden im Dienst durch Schichtdienst, Lärmexposition und sitzende Tätigkeiten verzeichnet. Gleichzeitig existieren Lücken in der Erfassung psychischer Belastungen und in der systematischen Dokumentation des Dienstsports. Darüber hinaus wurde festgestellt, dass bislang keine einheitlichen Trainings- oder Testungsverfahren für den Dienstsport vorhanden sind, sodass die körperliche Leistungsfähigkeit der Einsatzkräfte nicht regelmäßig überprüft oder gezielt gefördert wird. Die Einsatzkräfte äußerten ein hohes Interesse an strukturierten Trainings-, Resilienz- und Teammaßnahmen sowie den Bedarf an niederschwelligen Unterstützungsangeboten. Jedoch wurde eine geringe Bereitschaft zur aktiven Mitgestaltung verzeichnet. Schlussfolgerung: Auf Grundlage der Analyse wurde ein modular aufgebautes und EASA-konformes BGM-Konzept entwickelt. Das Konzept umfasst eine jährliche sportmedizinische Leistungsdiagnostik, individualisierte Trainingspläne, Peer-Support-Strukturen, Maßnahmen zur Resilienzförderung, Schulungen für Führungskräfte sowie partizipative Team- und Kommunikationsformate. Darüber hinaus bietet es einen praxisorientierten Ansatz zur strukturierten Gesundheitsförderung in sicherheitsrelevanten Einsatzbereichen und kann unter Berücksichtigung lokaler Rahmenbedingungen auf andere Regionalflughäfen übertragen werden.

UVA and UVB radiation in particular cause hair to become drier and more porous, making it more prone to structural damage. These effects can be attributed to the breakdown of the hair protein keratin. Suitable in vitro and ex vivo models were used to demonstrate the degradation of hair keratin by UV radiation and to illustrate this visually using real strands of hair. The aim of this work was to develop physically effective protection for hair against UV radiation and to demonstrate the protective effect of such sunscreen products on hair keratin using a specially developed methodology. In line with the current trend toward “skinification” concepts and formulation approaches from facial care were transferred to the hair care sector. For this purpose, a sun protection spray with modern oil-soluble and water-soluble UV filters was developed. Particular attention was paid to the optimal solution of the UV filters in an aqueous O/W emulsion and the subsequent sprayability of the emulsion in order to be able to apply the product evenly to the hair. The aspect of sustainability also played an important role in the selection of raw materials and the manufacturing process. In vitro tests were performed on specially manufactured keratin-containing agarose plates, irradiated with UV light, and then evaluated photometrically using a BCA assay. The samples treated with the product showed a significantly higher keratin content compared to untreated samples, indicating a protective effect against UV-induced keratin degradation. In addition, ex vivo tests on real hair strands confirmed a positive effect of the product treatment on the appearance and feel of the hair. The methodology developed represents an innovative approach to investigating the protective effect of hair sunscreen products on hair keratin and provides a basis for further research and product development. However, adjustments and optimizations of the formulation are necessary for standardization of the methodology.

Astrocytes play a crucial role in mediating oxidative stress caused by physiological processes, such as the byproducts of mitochondrial function during cellular respiration. Given the critical role of oxidative stress in the progression of many neurodegenerative diseases, identifying molecules capable of modulating this response and mitigating oxidative damage is of considerable interest. Cannabinoids such as cannabidiol (CBD) and WIN 55.212-2, known for their capability of influencing the endocannabinoid system through their interaction with cannabinoid receptors (namely, CB1R and CB2R), and therefore the Central Nervous System, are promising candidates for such modulation. This work aimed to explore, through proteomics, the potential effect that the mentioned cannabinoids might have against oxidative stress induced by hydrogen peroxide in astrocytes, possibly mitigating some of the oxidative damage.

The fate of bioplastic waste, especially packaging waste, remains largely unexplored in existing waste management systems. Anaerobic digestion (AD) is considered as a viable end-of-life option for bioplastics, however, current research has been primarily limited to lab-scale studies. This study investigated the anaerobic digestion of film samples made from Bioplast 106, PBAT, PLA and Ecovio (PLA/PBAT blend) under mesophilic and thermophilic conditions in pilot-scale biodigesters. The results of 90-day thermophilic AD demonstrated that PLA and Ecovio exhibited significant biodegradation of 36% and 50% by dry mass loss, respectively, while Bioplast 106 exhibited moderate biodegradation of 22.22%. The collective methane yield from these three bioplastics was 322.86 mL CH4/g VS, indicating their potential for biogas production. SEM and FT-IR analyses confirmed structural degradation of Bioplast 106, PLA, and Ecovio, while no degradation was observed for PBAT. PBAT showed high resistance to AD in pure and blended form (Bioplast 106, Ecovio). Bioplast 106 exhibited diverse degradation patterns, influenced by feedstock type, digester temperature, and processing conditions. This study might serves as valuable reference for assessing the anaerobic biodegradability of Bioplast 106 in pilot-scale biodigesters. This study further highlights the necessity of optimization of pilot-scale AD conditions to enhance the anaerobic biodegradability of slow-degrading bioplastics.

The sustainable harvesting and commercialization of non-timber forest products (NTFPs) offer a potential alternative, contributing to sustainable development by enhancing rural livelihoods, promoting environmental conservation, fostering economic diversification, empowering vulnerable socio-economic groups, and encouraging sustainable resource management. Among Cerrado's promising NTFPs is the Baru nut (Dipteryx alata), a nutrient-dense product rich in protein, fiber, zinc, and healthy oils, with potential therapeutic applications for various health issues. Its unique composition and versatility present an opportunity for sustainable commercialization that enhances rural livelihoods while promoting health benefits. Incorporating Baru-related products into local, national, and international markets could diversify economic opportunities while maintaining environmentally sustainable practices in both production and commercialization. Despite its potential, research on Baru remains scarce, creating a knowledge gap in the dynamics and challenges of its value chain. This study addresses this gap by employing a mixed-methods approach to evaluate the financial performance of each stage of the Baru value chain and identify existing challenges and market opportunities. Focused on Arinos, Minas Gerais, the research incorporates 29 interviews with local value chain actors, 14 supplementary interviews with institutional stakeholders, and secondary data analysis. The findings reveal a fragmented and predominantly informal value chain at the local level, faced with challenges such as physically intensive work, unreliable demand, power imbalances, low-profit margins, and limited institutional support. This research proposes strategies to foster collaboration, equity, transparency, and sustainable development of Baru’s value chain and contributes to a deeper understanding of this NTFP.

N2 - Ziel der vorliegenden Arbeit war es den Einfluss zwischen Wertschätzung am Arbeitsplatz, wahrgenommener organisationaler Unterstützung (POS) und psychologischer Sicherheit mit der Arbeitszufriedenheit, Absentismus und Fluktuationsabsicht anhand einer deutschen Stichprobe zu untersuchen. Es wurde zudem erwartet, dass Wertschätzung eine vermittelnde und moderierende Rolle hinsichtlich der wahrgenommenen organisationalen Unterstützung einnimmt. Dazu fand eine Querschnittsuntersuchung vom 02.12. bis 18.12.2024 mittels Online-Fragebogen statt. Zum Einsatz kamen größtenteils bewährte Messinstrumente der quantitativen Forschung. Für die Messung des Absentismus in Form von krankheitsbedingten Fehlzeiten wurde ein Item aus der empirischen Forschung gebildet. Zudem wurden demografische Daten (z.B. Alter, Geschlecht, Arbeitszeitmodell) erfasst. Nach Bereinigung der Stichprobe umfasste diese 55 deutsche Teilnehmende im Alter von 20 bis 66 Jahren, wobei 53% weiblich und 47% männlich waren. Es zeigte sich, dass Wertschätzung am Arbeitsplatz isoliert und im Zusammenspiel mit POS einen Einfluss auf die Arbeitszufriedenheit und Fluktuationsabsicht von Mitarbeitenden hat. Des Weiteren konnte Wertschätzung den Effekt von POS auf die Arbeitszufriedenheit partiell vermitteln. Zudem konnte ein signifikanter Interaktionseffekt zwischen POS und Wertschätzung auf den Absentismus gezeigt werden.

Since the implementation of economic reforms in 1978, China has transitioned from a largely agrarian society to a global industrial powerhouse, profoundly influencing international markets. This study investigates how China’s rapid industrialization and expanding demand for raw materials, such as oil, steel, and copper, have led to price fluctuations worldwide, contributing to rising commodity prices while simultaneously driving down costs in the consumer goods sector through low-cost manufacturing exports. By reviewing existing literature and analyzing economic data, this research seeks to identify the key mechanisms linking China’s economic activities to global price changes. This study provides insights into the potential impacts of similar developmental trajectories in other emerging economies, illustrating how economic policies, resource demands, and export-driven manufacturing contribute to shaping global market trends. Findings from this thesis can aid policymakers, economists, and business leaders in anticipating future global economic patterns driven by rising emerging economies.

Despite a shared emphasis on visually appealing fashion and moderate sustainability knowledge, participants showed a limited inclination towards sustainable choices. Notably, price takes precedence, reflecting a prevalent budget-conscious approach. Surprisingly, participants exhibit a low preference for consistency, challenging the expectation of significant cognitive dissonance in their fashion choices. The results suggest a minimal role of cognitive dissonance, indicating a relaxed decision-making style. The study underscores the dominance of ultra-fast fashion, design, and affordability in participants' choices. Future research is encouraged to address and reduce Gen-Z's (ultra-) fast fashion consumption, promoting sustainability knowledge and a greater preference for sustainable fashion.

N2 - In today’s fast-changing world, innovation is essential for staying competitive and makes it very important to understand what leads to the success or failure of innovations. This thesis examines the question: “How can lessons from failed innovations be used to improve organizational strategies and boost future innovation success?”. With the help of a comprehensive analysis of case studies involving mainly failed innovations, this study identifies the key lessons that companies learn from past failures. Using a solid theoretical framework, including the innovation matrix and innovation management success factors, the study highlights the importance of organizational learning, the importance of corporate identity, adaptability and strategic alignment. The results of this paper show that companies can improve their innovation strategies by analyzing failures in a systematic way, embracing a culture of defensibility and implementing structured processes for regular improvement. The results also show that a company’s own corporate identity, combined with the loyalty of its customers, can sometimes be of great value. The study contributes to innovation management by providing actionable recommendations for innovators trying to manage the complexity of innovation in a fast-changing environment. Finally, the insights gained from this study emphasize the value of learning from mistakes as a path to sustainable innovation success.

The primary goal of this research is to create an application that intends to facilitate autonomous learning while streamlining data processing, visualization, and reporting for the Bait Lamina Method (BLM). Advanced technologies such as React.js, Tailwind CSS, Vite.js, and several Node.js modules were used to implement essential functionalities. Moreover, to ensure smooth and scalable app delivery, Docker was employed. Furthermore, thorough usability testing was carried out with students from both the school and university to create a sturdy app that satisfies the needs and standards of users. This research utilized a mixed-methods approach to evaluate the app's overall usability, emphasizing efficiency, learnability, dependability, and overall satisfaction. Quantitative analysis included phi coefficient correlation, chi-square testing, and multiple ordinary least squares (OLS) regression to measure overall usability and user satisfaction. Meanwhile, qualitative approaches such as theme and sentiment analysis were used to get insight into user experiences, preferences, difficulties, and ideas for improvement. The study demonstrated that understanding the method is a key driver influencing student satisfaction. Therefore, the Bait Lamina App (BLA) immensely facilitated autonomous learning while speeding up data processing, visualization, and administration for the BLM. However, a few small faults and student comments were integrated into the BLA, which improved its use and satisfaction.

Conducted on a commercial dairy farm in Bedburg-Hau, Germany, the research involved 40 calves divided into eight groups (n1, 2 = 14, n3, 4 = 6, and n5, 6, 7, 8 = 20) with dry TMR provided to odd-numbered groups and wet TMR to even-numberedgroups. The experiment monitored daily feed intake and health parameters from birth to at least six weeks of age for heifer calves from two groups and from birth to three weeks of age from further two groups, and from birth to four weeks for bull calves, alongside weekly assessments of growth progression. T-test results did not reveal significant differences among the examined parameters when various groups were compared head-to-head. However, observable differences were noted, specifically in the amount of feed intake during the first few weeks, where calves fed dry TMR showed increased feed intake. Additionally, calves fed dry TMR exhibited less susceptibility to digestive disorders and a subsequent need for clinical treatment. Regarding sustainability, dry TMR showed advantages in ease of handling and storage, reducing time investment and feed waste. Wet TMR showed advantages in palatability and feed intake nearing the 5-week mark of the calves’ age. However, wet TMR posed challenges, in terms of time required for its preparation. These findings provide insights into optimizing calf nutrition, promoting sustainable dairy farming practices, and addressing the challenges of different feed alternatives.

The proposed method offers significant advantages, including cost and time efficiency, design flexibility, and biocompatibility, paving the way for innovative micromechanical and biomedical sensing applications. Moreover, this technique would enable the integration of fully additive manufacturing methods for Kapton® production, which currently relies primarily on subtractive manufacturing technologies. The thesis outlines the fabrication process, highlights optimal laser settings, and demonstrates the practicality of this technique by developing a water detector sensor manufactured entirely from the precursor liquid using the described method.

This thesis investigates both reasons and demographic factors (e.g., age, education, political orientation, etc.) influencing these trust dynamics as a result of the pandemic. Two countries with distinct cultural and socioeconomical differences are considered: Germany and Nigeria. Through a mixed-methods analysis of a pre-tested, pre-registered, cross-sectional online survey conducted in Germany and Nigeria in February 2023, several patterns are identified. The COVID-19 pandemic drove an increase in trust in science in both countries, while a marginal increase in trust in journalism was observed in Nigeria and a substantial decrease in Germany; this decline affected all demographics in the latter country. The thesis concludes with an outlook on further research. This includes conducting follow-up interviews to additionally explore reasons behind reported trust changes as well as the relationship between demographic factors and trust levels; performing a larger-scale survey with the aim of statistical significance and generalisability is further recommended.

Our research explores whether there is a statistical significance in the perceived difficulty of texts based on their authorship (human-translated to layman language, AI-translated, and original excerpts from a medical book), the correlation between participants' evaluations of text difficulty and quantitative analysis of these texts using JASNOPIS, and the relationship between health literacy levels and the ability to recognise AI-generated work. Additionally, the study examines the impact of exposure to AI-made writing on recognising AI-generated content and the relationship between health literacy levels and perceived text difficulty. A cross-sectional survey was conducted with 94 participants, collecting data through online questionnaires between September 19, 2024, and October 9, 2024. Key findings include significant correlations between average perceived difficulty and several JASNOPIS variables. The study also highlights the lack of a significant relationship between exposure to AI-made writing and the ability to recognise AI-generated work. However, the findings indicate that individuals who scored higher on health literacy tests perceived the texts to be easier. The implications of this research emphasise the importance of enhancing health-related and educational materials using plain language principles to improve accessibility and comprehension. Future studies should consider using more objective measures to avoid the influence of personal biases.

However, these objects were never meant for good, but rather instruments of colonial control. Over time, the local population adopted their names into everyday language, turning them into loanwords. Today, while most traces of the colonial era have faded, these loanwords persist. This raises a crucial question: Do loanwords serve as remnants of colonialism? And what role can a designer play in reclaiming them?

The custom board in this project, referred to as the USB2LORA board, is a printed circuit board (PCB) that integrates a FT232H USB 2.0 high-speed chip with a wireless LoRa transceiver. The primary objective of this thesis is to investigate how effective USB sniffer is in debugging and analyzing USB traffic between a USB device and a USB host, verifying the USB traffic against the standard, and detecting potential anomalies in communication. Using the USB sniffer, I successfully captured the essential USB communication processes, including the host’s recognition of the USB2LORA boards, retrieval of its configuration details, and the exchange of control commands and data between the USB2LORA boards and the USB host. During the recognition phase, the host requested and retrieved information about the USB2LORA board, containing its configuration, the type of data it can send and receive, and details about the buffers used to store or prepare the data during USB transmission. In subsequent data exchange phases, the results show that the host effectively sent control commands to configure the USB chip and to initiate communication with the wireless transceiver. The observed USB traffic aligned well with the USB standard and confirmed the correct behavior of the USB2LORA boards. Overall, the incorporation of a USB sniffer into the development and verification process of a custom USB board allows effective debugging of USB traffic and ensures adherence to the USB specification. Moreover, it enables developers to confirm the expected behavior of their software and their USB peripheral board as well as detect any anomalies in the communication.

Diese Faktoren führen zu erheblichen psychischen und physischen Beanspruchungen, die sich auf die Arbeitszufriedenheit und die pädagogische Qualität auswirken können. Ziel dieser Bachelorarbeit ist es, individuelle und institu-tionelle Strategien zur Bewältigung dieser Belastungen zu untersuchen. Mithilfe einer anonymen Onlineumfrage und eines Experteninterviews wurden so-wohl persönliche als auch strukturelle Bewältigungsmechanismen erfasst. Die Er-gebnisse zeigen, dass Fachkräfte vor allem auf soziale Unterstützung, sportliche Aktivitäten und informelle Gespräche mit Kolleginnen und Kollegen setzen, wäh-rend professionelle Hilfsangebote wie Supervision oder Coaching selten genutzt werden. Institutionelle Maßnahmen wie Fortbildungen und Teambuilding-Aktivitäten werden zwar als hilfreich wahrgenommen, sind jedoch häufig unzureichend vor-handen. Theoretisch unterstreichen die Ergebnisse die Bedeutung von Schutzfaktoren wie Resilienz, sozialer Unterstützung und einer positiven Arbeitsumgebung. Praktisch ergibt sich daraus die Notwendigkeit, betriebliche Gesundheitsförderung auszu-bauen, Arbeitsbedingungen durch bessere Personalbemessung und flexible Struk-turen zu optimieren und Leitungskräfte gezielt in der Förderung eines gesunden Arbeitsklimas zu schulen. Nur durch eine Kombination individueller und institutio-neller Maßnahmen kann langfristig eine nachhaltige Verbesserung der Arbeitsbe-dingungen pädagogischer Fachkräfte erreicht werden.

Previous studies have emphasized the significant impact of design and ecolabel elements in capturing consumers’ attention and influencing their preferences. However, only a limited number of studies have explored the effect of individual ecolabel elements and their orchestration in regard to visual attention and consumers perception, particularly in the context of textile products. The aim of the present study was to provide new insights into effective ecolabel design practices by investigating the influence of color, visual symbol, and text on consumers’ visual attention, environmental product perception and purchase intention. The current study employed a mixed method approach, combining quantitative and qualitative methods. The integrated methods included a review of existing ecolabels in the textile industry, an eye tracking experiment with sixteen custom-designed ecolabels, questionnaires, interviews, and a card sorting task. Visual attention was measured with the eye tracking, while other methods were employed to deepen the understanding of consumers’ perception and reasoning behind their decision-making. The results of the study revealed that the green ecolabels with natural symbols, such as Cotton and Leaf, received the highest environmental friendliness and purchase intention ratings, with the green Cotton ecolabel demonstrating the highest rate of visual attention engagement. In contrast, blue ecolabels were perceived as less environmentally friendly, particularly those with the visual symbols unrelated to nature. In addition, precise environmental claims with numerical data, such as “90% Organic cotton”, in combination with a website link, had a positive impact on trust and environmental perception. However, their role in visual attention and environmental perception was found to be less significant compared to the color and visual symbol. The findings contribute to textile research, highlighting the importance of the ecolabel context, visual symbol and color in ecolabel design, and providing new insights about visual attention patterns. The study outlines practical recommendations that can be utilized by professionals developing or redesigning ecolabels, in order to effectively communicate the characteristics of sustainable products.

N2 - Lebanon faces a significant energy crisis characterized by unreliable electricity supply, political instability, and outdated infrastructure. This thesis explores the potential of solar energy as a sustainable solution to address these challenges, focusing on economic, technical, and regulatory barriers while drawing comparative insights from Cyprus’s renewable energy model. The research examines three primary questions regarding the economic and technical challenges hindering solar energy adoption in Lebanon, the lessons that can be learned from Cyprus to inform solutions, and the comprehensive strategies that can support the development of Lebanon’s solar energy sector. The findings reveal that while Lebanon has experienced rapid growth in solar energy adoption, the sector is undermined by systemic issues such as low-quality imports, skill gaps, insufficient grid infrastructure, and the dominance of diesel generators. Comparative analysis with Cyprus underscores the importance of robust regulatory frameworks, financial accessibility, public-private partnerships, and accreditation systems for solar installers. Additionally, the analysis highlights the critical role of improving capacity factors in Lebanon, with findings showing that even a 1% increase could supply power to over 16,000 homes, emphasizing the potential efficiency gains for Lebanon’s solar energy sector. The thesis also evaluates Lebanon’s progress toward its 2030 renewable energy targets, noting that while the country appears to have met these targets in percentage terms, the achievement is largely a result of reduced electricity generation rather than genuine renewable capacity growth. Recommendations include enforcing quality standards, establishing national accreditation systems, addressing corruption, and leveraging international funding for infrastructure modernization and workforce development. This research emphasizes that Lebanon’s transition to renewable energy is not only a technical and economic endeavor but also a pathway to greater energy independence and environmental sustainability.

N2 - Plastic pollution has been one of the significant challenges worldwide. We must develop innovations and recycling technologies with millions of tons of plastic produced annuallyThe amount of plastic waste in landfills, seas, and ecosystems has been seriously degrading the environment. New innovative ideas for reducing plastic waste, such as biodigesters and composting methods, are being utilized worldwide. This research examines options such as anaerobic biodigesters and composting techniques to improve plastic breakdown in controlled atmosphere conditions. In anaerobic digestion, digestion happens with the help of microbial organisms as they help break down the organic materials without oxygen and break down the plastics, simultaneously generating renewable energy resources. This research evaluates polymers developed through a blown film extrusion process at different temperatures, such as Polylactic Acid (PLA), Polybutylene Adipate Terephthalate (PBAT), Polyhydroxybutyrate-co-hydroxy hexanoate(PHBH), Bioplast GF 106, and Ecovio, under anaerobic conditions. The degradation results of polymers after a specific period were analyzed based on their mechanical and chemical properties. The research aimed to assess the rates and effectiveness of plastic decomposition in biodigesters compared to conventional degradation methods while also exploring the viability and scalability of biodigesters for managing plastic waste. This research provides information on the degradation of polymers under anaerobic conditions and how the temperature produced affects their degradation, along with methane production. This information could inform future strategies and regulations focused on decreasing plastic pollution and improving sustainability.

The project examines the works of Jane Austen, Virginia Woolf, Emily Brontë, and Sylvia Plath, among others, analyzing how their narratives subvert traditional roles and redefine themes of love, identity, and autonomy. Interwoven with contemporary reflections, interviews, and cultural references, the book bridges past and present, demonstrating the enduring relevance of these feminist perspectives. Beyond textual analysis, the project integrates visual storytelling as a critical tool for interpretation. The design of the book reinforces its themes through intentional typography pairings, a muted blue color scheme, and abstract imagery composition derived from historical paintings of women in positions of power, longing, or introspection. Black rectangles symbolize censorship, while scattered ink-like dots highlight both presence and absence—the stories told and those erased. Gradients subtly disrupt the running text, visually mirroring the fading and resurfacing of female voices over time. By combining literary scholarship with graphic design, Unleashed Minds is both an academic investigation and a tactile experience, reinterpreting feminist narratives through form and content. The project stands as a complete and cohesive work, emphasizing the power of design in reshaping and reclaiming women’s place in storytelling.

N2 - Anomaly detection is an important aspect of beehive monitoring, enabling beekeepers to take timely action and preventing economic losses caused by the decline of the bee population. Most existing beehive monitoring systems lack machine learning (ML) capabilities for anomaly detection and rely on threshold-based methods or expensive, complex designs. This thesis utilized the DigiBee prototype, a cost- effective monitoring system, to develop an ML-based anomaly detection model using Isolation Forest. Data on temperature, humidity, sound, vibration, and weight from four active beehives was collected between May 1, 2024, and July 25, 2024, alongside environmental data—temperature, relative humidity, and precipitation—from nearby meteorological stations. Exploratory data analysis revealed several limitations: uniform outputs from vibration sensors, calibration errors in weight sensors, and multiple gaps during the data collection period. Correlation analysis indicated a limited influence of external weather variables on internal beehive conditions, while internal sensor parameters displayed stronger correlations with each other. Five models were developed, using either beehive data alone or a combination of beehive and weather data. Results showed that beehive-specific models achieved higher accuracy in detecting localized anomalies, whereas models combining data from multiple beehives generalized better but underrepresented hive-specific issues. Models incorporating weather parameters, especially precipitation, introduced noise and unnecessary dimensions, which, when excluded, improved the model’s prediction by focusing on hive-specific patterns and ensuring anomaly detection remained contextually relevant.

Inwieweit hat dies Effekte auf die affektive Bindung sowie die Mitarbeitendenzufriedenheit? N2 - Frühere Studien, insbesondere die Metaanalyse von Frazier et al. (2017), zeigen, dass psychologische Sicherheit eine Schlüsselrolle für Arbeitszufriedenheit und organisationales Commitment spielt. Der Einfluss agiler Arbeitsweisen wurde in diesem Zusammenhang jedoch bisher kaum untersucht. Diese Studie widmet sich der Frage, wie agile Arbeitsweisen, insbesondere das Scrum-Rahmenwerk, die psychologische Sicherheit, das affektive Commitment und die Arbeitszufriedenheit beeinflussen. In einem mittelständischen Unternehmen wurde eine Intervention im Rahmen einer Studie mit Pre-Posttest-Design (N = 37) durchgeführt. Eine Interventionsgruppe arbeitete nach dem Scrum-Rahmenwerk, einschließlich zweiwöchiger Sprints und agiler Events, während die Kontrollgruppe ohne agiles Rahmenwerk arbeitete. Die Ergebnisse zeigen, dass psychologische Sicherheit ein signifikanter Prädiktor der Arbeitszufriedenheit und des Commitments war - jedoch nur im Prätest. Agiles Projektmanagement erhöhte die psychologische Sicherheit nicht signifikant, was auf die moderierende Rolle von Stress und organisatorischen Rahmenbedingungen hinweisen könnte. Affektives Commitment erwies sich hingegen über beide Messzeitpunkte hinweg als stabiler Einflussfaktor auf die Arbeitszufriedenheit. Die vorliegende Arbeit liefert weitere Einblicke in die Bedeutung von psychologischer Sicherheit und Commitment in agilen Arbeitskontexten, betont jedoch, dass deren Entwicklung nicht automatisch durch agile Arbeitsweisen gefördert wird. Aufgrund methodischer Limitationen sollten die Ergebnisse differenziert betrachtet werden. Die Befunde bieten praktische Anhaltspunkte, dass ergänzende Maßnahmen wie systemisches Stressmanagement zur Reduzierung von Stress auf organisationaler und individueller Ebene sowie Weiterbildungen für Führungskräfte, die Vertrauen und Teamstabilität fördern, notwendig sind, um die potenziellen Vorteile agiler Methoden vollständig zu auszuschöpfen.

The study addresses three core research questions: the specific difficulties faced by migrant workers in accessing adequate housing, fair labor rights, and social security; the role of EU directives and Member State discretion in shaping labor protections; and the enforcement gaps impacting workers’ rights and well-being. A qualitative approach was applied, focusing on the analysis of EU regulations, national policies, and case studies to identify systemic barriers and regulatory inconsistencies. The findings reveal significant disparities in housing standards, labor conditions, and access to social security, driven by divergent interpretations of EU directives by Germany and the Netherlands. Additionally, the lack of coordinated cross-border enforcement amplifies these issues, leaving many migrant workers vulnerable to exploitation. The study concludes that addressing these challenges requires enhanced cross-border cooperation, greater regulatory alignment, and targeted policy reforms to bridge the enforcement gaps. These recommendations aim to uphold the EU’s core value of free movement while ensuring social equity for migrant workers. This research contributes to the broader discourse on labor mobility by highlighting the interplay between legal frameworks and social justice in cross-border regions.
