  abstract  = {F{\"u}r die Authentizit{\"a}tsbewertung achiraler Aromastoffe ist die gaschromatographische Isotopenverh{\"a}ltnismessung mittels massenspektrometrischer Analyse ein etabliertes Verfahren. Diese Technik erm{\"o}glicht es, {\"u}ber geeignete Datenbanken authentischer Referenzproben gesicherte Aussagen hinsichtlich deren Herkunft aus nat{\"u}rlicher oder synthetischer Quelle zu treffen. Zunehmend ins Interesse r{\"u}ckt allerdings auch die Frage, ob es mittels Techniken der Stabilisotopenanalytik ebenso m{\"o}glich ist, das breite Feld der legislativ als „nat{\"u}rlich" deklarierten Aromastoffe analytisch weiter in deren Herkunft aus biotechnologischer oder nat{\"u}rlicher („ex plant") Quelle aufzutrennen. Zwar kann dieser Fragestellung prinzipiell {\"u}ber die Erweiterung bestehender Stabilisotopen-Datenbanken mit authentischen Proben nachgegangen werden, sie scheitert jedoch h{\"a}ufig an der limitierten Verf{\"u}gbarkeit authentischer biotechnologischer Referenzen oder der eingeschr{\"a}nkten Kenntnis {\"u}ber die der Produktion „nat{\"u}rlicher" Aromastoffe zugrundeliegenden Verfahrenstechniken. Eine m{\"o}gliche Vorgehensweise zur Umgehung dieses Sachverhalts stellt daher die in Anlehnung an beschriebene biotechnologische Verfahren im Labormaßstab durchgef{\"u}hrte Produktion ausgew{\"a}hlter und somit auch authentischer Referenz-Aromastoffe dar. Diese Methode hat zudem den Vorteil, dass gegebenenfalls zus{\"a}tzliche Informationen {\"u}ber m{\"o}gliche Isotopenfraktionierungen in solchen Systemen ermittelt werden k{\"o}nnen, welche sich nicht nur zur Authentizit{\"a}tspr{\"u}fung als n{\"u}tzlich erweisen k{\"o}nnen, sondern auch zur stetig wachsenden Grunderkenntnis {\"u}ber Isotopenfraktionierungen in biologischen Systemen beitragen. Ziel der vorliegenden Arbeit war es daher, der geschilderten Fragestellung bez{\"u}glich ausgew{\"a}hlter Aromastoffe aus den Gruppen der C6-Aldehyde und -Alkohole („Gr{\"u}nnoten") sowie der G{\"a}rungsalkohole nachzugehen. Zu diesem Zweck erfolgten zum einen im Labormaßstab die biogenetische Bildung von C6-Aldehyden und -Alkoholen ausgehend von den unges{\"a}ttigten Fetts{\"a}uren Linol- und Linolens{\"a}ure, ferner wurden parallel Edukte, Intermediate und Produkte isoliert und hinsichtlich ihrer Stabilisotopengehalte durch Bestimmung der Delta-2H(V-SMOW)- und Delta-13C(V-PDB)-Werte untersucht. Zum anderen sind auf fermentativem Wege ausgehend von unterschiedlichen Kohlenhydratquellen die G{\"a}rungsalkohole 2-Phenylethanol und 2-Methyl-1-propanol dargestellt worden. Des weiteren galt es, die bei den G{\"a}rungsalkoholen resultierende Datenlage dahingehend zu pr{\"u}fen, ob sich diese {\"u}ber eine Korrelation der Delta-2H(V-SMOW)- und Delta-13C(V-PDB)-Werte dazu eignet, eine Authentizit{\"a}tsbewertung dieser Aromastoffe hinsichtlich nat{\"u}rlicher oder synthetischer Herkunft zu erm{\"o}glichen.},

  abstract  = {Social robots are becoming increasingly prevalent in everyday life and sex robots are a sub-category of especially high public interest and controversy. Starting from the concept of the otaku, a term from Japanese youth culture that describes secluded persons with a high affinity for fictional manga characters, we examine individual differences behind sex robot appeal (anime and manga fandom, interest in Japanese culture, preference for indoor activities, shyness). In an online-experiment, 261 participants read one out of three randomly assigned descriptions of future technologies (sex robot, nursing robot, genetically modified organism) and reported on their overall evaluation, eeriness, and contact/purchase intentions. Higher anime and manga fandom was associated with higher appeal for all three future technologies. For our male subsample, sex robots and GMOs stood out as shyness yielded a particularly strong relationship to contact/purchase intentions for these new technologies.},

  abstract  = {Objective Global challenges such as climate change or the COVID-19 pandemic have drawn public attention to conspiracy theories and citizens' non-compliance to science-based behavioral guidelines. We focus on individuals' worldviews about how one can and should construct reality (epistemic beliefs) to explain the endorsement of conspiracy theories and behavior during the COVID-19 pandemic and propose the Dark Factor of Personality (D) as an antecedent of post-truth epistemic beliefs. Method and Results This model is tested in four pre-registered studies. In Study 1 (N = 321), we found first evidence for a positive association between D and post-truth epistemic beliefs (Faith in Intuition for Facts, Need for Evidence, Truth is Political). In Study 2 (N = 453), we tested the model proper by further showing that post-truth epistemic beliefs predict the endorsement of COVID-19 conspiracies and disregarding COVID-19 behavioral guidelines. Study 3 (N = 923) largely replicated these results at a later stage of the pandemic. Finally, in Study 4 (N = 513), we replicated the results in a German sample, corroborating their cross-cultural validity. Interactions with political orientation were observed. Conclusion Our research highlights that epistemic beliefs need to be taken into account when addressing major challenges to humankind.},

  abstract  = {When interacting with sophisticated digital technologies, people often fall back on the same interaction scripts they apply to the communication with other humans—especially if the technology in question provides strong anthropomorphic cues (e.g., a human-like embodiment). Accordingly, research indicates that observers tend to interpret the body language of social robots in the same way as they would with another human being. Backed by initial evidence, we assumed that a humanoid robot will be considered as more dominant and competent, but also as more eerie and threatening once it strikes a so-called power pose. Moreover, we pursued the research question whether these effects might be accentuated by the robot's body size. To this end, the current study presented 204 participants with pictures of the robot NAO in different poses (expansive vs. constrictive), while also manipulating its height (child-sized vs. adult-sized). Our results show that NAO's posture indeed exerted strong effects on perceptions of dominance and competence. Conversely, participants' threat and eeriness ratings remained statistically independent of the robot's depicted body language. Further, we found that the machine's size did not affect any of the measured interpersonal perceptions in a notable way. The study findings are discussed considering limitations and future research directions.},
