coronavirus disease 2019
No full textIn der historisch bezeugten Vergangenheit gab es bereits diverse Krankheitsausbrüche und daraus resultierende Epi- und Pandemien. Im Jahr 2019 trat erstmals das Virus SARS-CoV-2 auf, welches eine weltweite Pandemie auslöste. Aufgrund der vermuteten und in der Forschungsliteratur angedeuteten psychologischen Auswirkungen von Pandemien, wurden in der vorliegenden Studie die Emotionalen Belastungen von Studierenden während der ersten Phase der COVID-19 Pandemie untersucht. Hierfür wurden 377 deutschsprachige Studierende, die während der ersten Phase der COVID-19 Pandemie im Sommer 2020 studierten, mit 386 Studierenden aus dem Jahr 2016 verglichen. Mit dem Insomnia Severity Index, dem ENRICHD Sozial Support Inventory-Deutsch, der Allgemeinen Depressionsskala-Kurzversion, der Perceived Stress Scale sowie dem Penn State Worry Questionnaire, wurden die Schlafschwierigkeiten mit Schlafdauer, die soziale Unterstützung, die depressiven Symptome, der Stress und die Sorgen der Studierenden erhoben. Es zeigte sich, dass die Studierenden während der ersten Phase der COVID-19 Pandemie durchschnittlich länger schliefen und gestresster waren, als die Studierenden aus dem Jahr 2016. Zudem war ein Trend zu einer geringeren sozialen Unterstützung während der ersten Phase der COVID-19 Pandemie vorhanden. Weibliche Studierende schliefen grundsätzlich weniger pro Nacht, hatten häufiger Schlafschwierigkeiten, fühlten sich gestresster, machten sich mehr Sorgen und hatten mehr depressive Symptome als die männlichen Studierenden. Zugleich gaben sie an, besser sozial unterstützt zu werden als die männlichen Studierenden.In the historically documented past, various outbreaks of infectious diseases resulting in epidemics and pandemics have occurred. In 2019, the SARS-CoV-2 virus appeared for the first time, causing a global pandemic. Due to the psychological effects of infectious disease outbreaks as suggested in the research literature, the present study examined the emotional burden of university students during the first phase of the COVID-19 pandemic. For this purpose, 377 German-speaking university enrolled students who studied during the first phase of the COVID-19 pandemic in the summer of 2020 were compared with 386 university students from 2016. The Insomnia Severity Index, the ENRICHD Social Support Inventory-German, the German version of the Center for Epidemiological Studies Depression Scale, the Perceived Stress Scale and the Penn State Worry Questionnaire were used to measure sleep difficulties with sleep duration, social support, depressive symptoms, stress and worries. The results showed that students had a longer sleep duration during the first phase of the COVID-19 pandemic and reported a higher level of perceived stress than students in 2016. There was also a trend indicating that students received less social support during the first phase of the COVID-19 pandemic compared to the year 2016. Female students generally slept less per night, had more sleep difficulties, perceived more stress, worried more and had higher levels of depressive symptoms than the male students. At the same time, the female students received better social support than the male students did.vorgelegt von: Thomas ForstmeyerMasterarbeit Universität Innsbruck 202
boron nitride anions
No full textThis thesis presents the development and characterisation of an experimental setup designed for photodetachment spectroscopy of boron nitride anions (BN^-), as a step towards the long-term objective of laser cooling them. Laser cooling has become a mature and widely applied technique for neutral atoms and selected cationic molecular species, while its extension to anionic systems poses considerable experimental challenges. BN^- stands out as a promising candidate due to theoretical predictions of an electronic structure that features nearly diagonal Franck–Condon factors, suggesting the potential for closed optical cycling transitions—an essential prerequisite for laser cooling of molecular ions. Realising such a system would open new frontiers in precision spectroscopy, antimatter research, and ultracold chemistry involving negative ions.
To this end, the setup—comprising a plasma discharge ion source with a piezoelectric valve, a Wiley–McLaren-type time-of-flight mass spectrometer, a channeltron ion detector, and an OPO laser—was calibrated using various negative and positive ion species, enabling accurate conversion of time-of-flight data into mass-to-charge spectra with sufficient resolution to identify light ions. Initial attempts at producing BN^- via thermal decomposition of ammonia borane (H_3B-NH_3) were conducted. While unambiguous detection of BN^- remains pending, several boron-containing positive and negative ions were observed. To validate the photodetachment capabilities of the setup, proof-of-principle depletion spectroscopy was performed on the well-characterised species O^-, OH^-, and O_2^- . Significant signal reductions were observed upon laser interaction at 450 nm for all species, and at 700 nm solely for O^- and O_2^- , consistent with their known photodetachment cross sections. To enable detection of neutral species resulting from photodetachment and to mimprove charged-neutral separation, a quadrupole bender was designed, simulated using SIMION, and successfully implemented in the setup. The overall system is now operational and provides a robust platform for forthcoming spectroscopic investigations of BN^- and related molecular anions, laying the groundwork for advancing laser-cooling techniques in negatively charged systems.by Beke Leonie Breitmeier, BScIm Titel ist - jeweils hochgestellt Masterarbeit University of Innsbruck 202
Managerial performance and resilience through holistic energy management : a study in consulting firms
No full textIn today’s high-pressure consulting environments, sustained managerial performance and resilience demand more than time efficiency, they require effective energy management. This study explores how consulting managers regulate their physical, mental, emotional, and spiritual energy, and how these practices influence self-reported outcomes such as performance, stress management, and job satisfaction. Drawing on Energy Management Theory, the Job Demands–Resources Model, and Self-Determination Theory, a quantitative survey was conducted among consulting managers in the DACH region. Results indicate that physical and emotional energy management are positively associated with perceived performance and satisfaction, though statistical significance was constrained by the small sample size. The findings underscore the potential of holistic energy strategies as critical tools for leadership sustainability. By reframing energy and not time as the central currency of managerial effectiveness, this thesis contributes to theory and practice in organizational behavior and human resource development.Katrin DomabylMasterarbeit University of Innsbruck 202
Strukturen der Mimesis in der Wirtschaft von heute
No full textDer berühmte Literaturwissenschaftler, Kulturanthropologe und Religionsphilosoph René Girard beschreibt den Menschen anhand seiner Mimetischen Theorie. Der Kern seiner besteht im sogenannten „mimetischen Begehren“ des Menschen. Mimesis ist dem Menschen angeboren. Mimesis bezeichnet Nachahmung. Gemäß Girard ist diese auch im Bereich des Begehrens am Werk. Demnach sind Menschen nicht autonom, sondern richten ihr Begehren nach dem Begehren anderer Menschen aus. Es geht also um eine Nachahmung der Begierde eines anderen. Folglich begehren Menschen nicht unmittelbar ein Objekt an sich, sondern, weil ein anderer es begehrt. (vgl. Palaver 2004, 25f) In diesem Zusammenhang spricht Girard vom Konzept des „triangulären Begehrens“, welches die Struktur dieses mimetischen Begehrens darstellt. Abhängig von den Umständen und den Objekten, die begehrt werden, kann die Mimesis Positives (z.B., Kreativität, Forschungs- und Entdeckungsdrang), sowie Negatives (Rivalität, Gewalt) bewirken. (vgl. Palaver 2004, 60f)
Die vorliegende Masterarbeit analysiert aktuelle ökonomische Praxisfelder auf Basis der Mimetischen Theorie. Die Forschungsfrage wird wie folgt formuliert: Wo finden sich mimetische Verhaltensmuster in der ökonomischen Praxis?
Für die Beantwortung dieser Frage werden drei unterschiedliche Praxisfelder auf unterschiedlichen Ebenen in den Blick genommen: Finanzmärkte (Spekulationsblasen), Unternehmensentscheidungen (Imitationsstrategie), Konsummärkte (Influencebasiertes Konsumverhalten);
In allen drei Bereichen wird analysiert, inwiefern die Mimesis hier erkennbar ist und welche Auswirkungen diese mit sich bringt. Nachfolgend wird reflektiert, welche Probleme und/oder Vorteile dies für die Wirtschaft mit sich bringt.

Too close for comfort? : the double-edged sword of animal-like similarity in plant-based alternatives
No full textThe market for plant-based products has experienced significant growth in recent years, as an
increasing number of consumers choose to reduce or eliminate meat from their diets. This shift
presents marketers with a key strategic question: should plant-based alternatives mimic the
original animal products, or is it more effective to emphasize their uniqueness?
This master’s thesis investigates the impact of similarity between animal-based and plant-
based foods, with a specific focus on the effect of product naming on consumer responses
via perceived similarity. The central research question guiding this study was:
“How does the similarity in naming of plant-based alternatives and animal-based
products influence consumer responses?”
An exploratory between-subjects experiment was conducted in which participants (N = 207)
were randomly assigned to one of two groups. Each group evaluated an oat-based beverage that
was completely identical but labeled either as “oat milk” or “oat drink.” Participants assessed
the product’s taste, their purchase intention, and overall satisfaction, alongside perceived
similarity to cow’s milk, label attractiveness, eating habits, and demographic information.
The findings revealed that product naming had a direct effect on taste evaluation:
participants rated the taste of the beverage labeled "oat milk" significantly higher than that of
"oat drink." This effect was particularly pronounced among omnivorous consumers, who
appeared more sensitive to semantic cues reflecting animal-product imitation. While the term
"oat milk" elicited a higher level of perceived similarity, this perception did not significantly
mediate the relationship between naming and the main outcome variables (taste, purchase
intention, and satisfaction). Furthermore, no moderated mediation effects were found for the
variables gender, familiarity with oat drinks, consumption frequency, or diet type.
A key insight from the study was the central role of taste, which consistently predicted both
purchase intention and overall satisfaction, regardless of product name. These results suggest
that while naming can shape initial expectations, a satisfying sensory experience remains
critical to the success of plant-based alternatives. Therefore, marketers should prioritize taste
quality alongside branding, as naming alone is insufficient to ensure positive consumer
responses.written by Toni Katharina KoppAppendix in deutscher SpracheMasterarbeit University Innsbruck 202
