Guardians of the Metaverse: Expert Assessment of Emerging Privacy Challenges and Mitigation Strategies
The metaverse describes persistent and interconnected 3D multi-user environments that are characterized by the fusion of physical and virtual worlds. Fueled by the rebranding of Meta, the metaverse is experiencing a resurgence and has attracted the attention of practitioners and scholars, resulting in a new wave of publications. While cutting-edge technologies offer unprecedented immersive experiences, users face new privacy situations as metaverse technologies require extensive data collection. Additionally, the spatial nature of the metaverse allows for the observation of digital footprints. This changing context of data disclosure necessitates a re-evaluation of privacy. Building on the Multidimensional Development Theory as an overarching framework, I conducted 35 expert interviews, resulting in 16 emerging privacy challenges and corresponding privacy protection measures. With these findings, this paper contributes to research on today’s metaverse by empirically investigating privacy as a crucial aspect and providing practical recommendations for organizations to mitigate negative user reactions
Unveiling Stakeholder Perspectives on Privacy in the Metaverse: Case Study of a German Car Company
Companies have turned their attention to becoming part of the metaverse, a persistent, multi-user, three-dimensional environment characterized by the fusion of virtual and physical elements. While the metaverse offers new ways to create value, related software and hardware components require massive amounts of user data, which can raise privacy concerns. In addition, privacy regulation is in its infancy, creating uncertainty about how to operate in a compliant manner. Building on the multi-stakeholder privacy framework, we explored the privacy stakeholders’ (user, management, policymakers) perspectives on the metaverse, analyzed their relationships, and identified measures to align their interests within a single case study of a German car company. The contribution is twofold. First, we demonstrate the importance of involving privacy stakeholders in the design of products and services in new online environments. Second, we propose privacy measures to reconcile the stakeholders’ interests in the metaverse, providing implications for managers and policymakers

A Dual-Mode Surface Acoustic Wave Delay Line for the Detection of Ice on 64°-Rotated Y-Cut Lithium Niobate
Ice accumulation on infrastructure poses severe safety risks and economic losses, necessitating effective detection and monitoring solutions. This study introduces a novel approach employing surface acoustic wave (SAW) sensors, known for their small size, wireless operation, energy self-sufficiency, and retrofit capability. Utilizing a SAW dual-mode delay line device on a 64°-rotated Y-cut lithium niobate substrate, we demonstrate a solution for combined ice detection and temperature measurement. In addition to the shear-horizontal polarized leaky SAW, our findings reveal an electrically excitable Rayleigh-type wave in the X+90° direction on the same cut. Experimental results in a temperature chamber confirm capability for reliable differentiation between liquid water and ice loading and simultaneous temperature measurements. This research presents a promising advancement in addressing safety concerns and economic losses associated with ice accretion

Der Anfang vom Ende der Ottonen
In the Chronicle of Thietmar of Merseburg, the experiences and problems of the tenth and early eleventh centuries come together they are taken up by Thietmar and formed into an epoch. This overall interpretation of the chronicle by the Bishop of Merseburg sees historical knowledge as a consistent product of a dynamic process, as an interplay of cultural and cognitive factors in a particular historical situation. On the basis of this dynamic concept of knowledge, it is possible to present a new interpretation of central episodes of Ottonian historiography and at the same time to demonstrate the future potential of images from the past
Hipotensión intraoperatoria no es sinónimo de hipovolemia
The introduction of echocardiography (TEE) in the evaluation of the hemodynamic status in non-cardiac surgery has been a key advance. TEE allows an early diagnosis of cardiac problems and to guide therapy with vasoactive drugs, beta-blockers or fluids following direct evaluation of cardiac function and avoid to guess what is happeningLa introducción de la ecocardiografía (ETE) como sistema de monitorización del estado hemodinámico en cirugía no cardíaca ha sido un gran avance. La ETE permite realizar un diagnóstico precoz y guiar la terapia con drogas vasoactivas, betabloqueantes y fluidos siguiendo las imágenes y mediciones del miocardio y cavidades cardíacas de manera directa y no intentando adivinar lo que ocurre
Kommunales Flächenmanagement und Flächenmonitoring: Umfrageergebnisse und Schlussfolgerungen
Für die Städte und Gemeinden ist die Flächennutzung eine wichtige Aufgabe der kommunalen Planungshoheit und Daseinsversorge. Der Verband Deutscher Städtestatistiker (VDSt) hat deshalb das Thema Flächenmanagement und Flächenmonitoring zu einem Schwerpunkt in Heft 2/2018 seiner Fachzeitschrift Stadtforschung und Statistik gemacht. Um mehr über die örtlichen Gegebenheiten beim Flächenmanagement und Flächenmonitoring
zu erfahren, haben der VDSt und die KOSIS-Gemeinschaft Kommunale Raumbezüge und Raumanalyse (KORIS) von Oktober 2017 bis April 2018 eine Online-Städteumfrage durchgeführt. Etwa 60 Städte haben sich beteiligt. Dieser Beitrag konzentriert sich auf die 49 Städte, die ein Flächenmanagement oder Flächenmonitoring (umfassend oder in Teilbereichen) betreiben oder es aufbauen. Berichtet wird über Anwendungsschwerpunkte
und Aufgaben des Flächenmanagements, über Organisation und Zuständigkeiten sowie über die konzeptionelle und stadtpolitische Fundierung und Verankerung. Beim Flächeninformations- und Monitoringsystem wird darüber hinaus auf die genutzten Datengrundlagen, die eingesetzten Instrumente und Basistechnologien sowie die Standardberichterstattung und deren Adressaten eingegangen
