To shed light on the consequences of videoconferencing at work, this study takes a granular look at the implications of the self-view feature for meeting outcomes. Building on self-awareness research and self-regulation theory, we argue that by heightening the state of self-awareness, self-view engagement depletes participants’ mental resources and thereby can undermine online meeting outcomes. Evaluation of our theoretical model on a sample of 179 employees reveals a nuanced picture. Self-view engagement while speaking and while listening is positively associated with self-awareness, which, in turn, is negatively associated with satisfaction with meeting process, perceived productivity, and meeting enjoyment. The criticality of the communication role is put forward: looking at self while listening to other attendees has a negative direct and indirect effect on meeting outcomes; however, looking at self while speaking produces equivocal effects.

These records can deliver valuable insights to approach problematic situations effectively. Our study explores how social media communication can be analyzed to understand the responses to health crises better. Results based on nearly 800 K tweets indicate that the coping and regulation foci framework holds good explanatory power, with four clusters salient in public reactions: 1) “Understanding” (problem-promotion); 2) “Action planning” (problem-prevention); 3) “Hope” (emotion-promotion) and 4) “Reassurance” (emotion-prevention). Second, the inter-temporal analysis shows high volatility of topic proportions and a shift from self-centered to community-centered topics during the course of the event. The insights are beneficial for research on crisis management and practicians who are interested in large-scale monitoring of their audience for well-informed decision-making.

BT - understanding the impact of appearance disclosure on accommodation sharing platforms T2 - Proceedings of the 53rd Hawaii International Conference on System Sciences N2 - Online photographs govern an individual’s choices across a variety of contexts. In sharing arrangements, facial appearance has been shown to affect the desire to collaborate, interest to explore a listing, and even willingness to pay for a stay. Because of the ubiquity of online images and their influence on social attitudes, it seems crucial to be able to control these aspects. The present study examines the effect of different photographic self-disclosures on the provider’s perceptions and willingness to accept a potential co-sharer. The findings from our experiment in the accommodation-sharing context suggest social attraction mediates the effect of photographic self-disclosures on willingness to host. Implications of the results for IS research and practitioners are discussed.

T2 - Responsible design, implementation and use of information and communication technology N2 - Increasingly, research attention is being afforded to various forms of problematic media use. Despite ongoing conceptual, theoretical, and empirical debates, a large number of retrospective self-report scales have been produced to ostensibly measure various classes of such behaviour. These scales are typically based on a variety of theoretical and diagnostic frameworks. Given current conceptual ambiguities, building on previous studies, we evaluated the dimensional structure of 50 scales targeting the assessment of supposedly problematic behaviours in relation to four technologies: Internet, smartphones, video games, and social network sites. We find that two dimensions (‘compulsive use’ and ‘negative outcomes’) account for over 50% of all scale-items analysed. With a median of five dimensions, on average, scales have considered fewer dimensions than various proposed diagnostic criteria and models. No relationships were found between the number of items in a scale and the number of dimensions, or the technology category and the dimensional structure. The findings indicate, firstly, that a majority of scales place an inordinate emphasis on some dimensions over others and, secondly, that despite differences in the items presented, at a dimensional level, there exists a high degree of similarity between scales. These findings highlight shortcomings in existing scales and underscore the need to develop more sophisticated conceptions and empirical tools to understand possible problematic interactions with various digital technologies.

Despite new technological advances such as cloud computing or model-driven development, technical ERP customization options are either outdated or ambiguously formulated in the scientific literature. Using a systematic literature review (SLR) that analyzes 137 definitions from 26 papers, the result is an analysis and aggregation of technical customization types by providing clearance and aligning with future organizational needs. The results show a shift from ERP code modification in on-premises systems to interface and integration customization in cloud ERP systems, as well as emerging technological opportunities as a way for customers and key users to perform system customization. The study contributes by providing a clear understanding of given customization types and assisting ERP users and vendors in making customization decisions.

Prof. Dr. Detlev Hummel, faculty Finance and Banking, was the host of the event. Academic colleagues from Beijing, Moscow and Connecticut (USA) as well as domestic capital market and banking experts presented their analyses. Different aspects of national and international finance markets were examined, with a focus on the European region, China and Russia. Mistakes and failures of the banking regulations were identified as one, but note the sole cause of the economic problems. A lack of budget discipline of some politicians and the loss of business competitiveness of certain European nations were mentioned, too. Some members of the European Union did not succeed in mastering the challenges of the global economy. There have been structural issues in some states that impede their competitiveness in the global market, for example with China. The participants pointed out a number of other reasons for the crisis, like dubious distribution types as well as a lack of transparency of certain financial products. Furthermore, remuneration and incentive schemas of investment banks and especially the reckless risk management policy of large banks were identified as other factors for the crisis. The participants of the international workshop in Potsdam agree that the birth of the Euro-currency was a political event and will remain a challenge. The reform of the banking supervision and further steps towards an economic and fiscal union are new research tasks. N2 - Am 20./21. Juli 2012 fand an der Universität Potsdam ein internationaler Erfahrungsaustausch über die globalen Folgen der Euro-Finanzkrise statt. Eingeladen hatte Prof. Dr. Detlev Hummel, Lehrstuhl für Betriebswirtschaftslehre mit dem Schwerpunkt Finanzierung und Banken. Kooperationspartner aus Peking, St. Petersburg und Moskau sowie Connecticut (USA), wie auch heimische Kapitalmarkt- und Bankexperten trugen Analysen vor. Es wurden unterschiedliche Aspekte aus Sicht nationaler und internationaler Finanzmärkte vorgestellt, wobei neben dem europäischen Raum auch China und Russland im Fokus standen. Die Ursachen der Euro-Finanzkrise wurden einerseits in einer unzureichenden Bankenregulierung gesehen. Eine mangelnde Haushaltsdisziplin politischer Entscheidungsträger und der Verlust der Wettbewerbsfähigkeit bestimmter europäischer Staaten standen ebenso zur Debatte. Teile der europäischen Gemeinschaft haben die Herausforderungen der Globalisierung nicht gemeistert. Es handelt sich hierbei um Strukturprobleme einzelner Staaten, die eine globale Wettbewerbsfä-higkeit, beispielsweise gegenüber China, verhindern. Weitere Ursachen - wie die teils fragwürdigen Vertriebsformen sowie die mangelnde Transparenz bestimmter Finanzprodukte, aber auch extreme Vergütungs- und Anreizmechanismen von Investmentbanken, vor allem aber die leichtfertige Risikopolitik großer Institute sowie Systemschwächen dabei - wurden aufgezeigt. Die Teilnehmer des internationalen Workshops in Potsdam waren sich darüber einig, dass die Einführung des Euro ein politisches Ereignis war und eine solche Herausforderung bleibt. Die Reform der europäischen Bankenaufsicht und weitere Schritte in Richtung einer wirtschaftlichen und finanzpolitischen Union stellen neue Aufgaben für die Forschung dar.

June 2015 N2 - Nearly 150 years ago, the French astronomers Charles Wolf and Georges Rayet described stars with very conspicuous spectra that are dominated by bright and broad emission lines. Meanwhile termed Wolf-Rayet Stars after their discoverers, those objects turned out to represent important stages in the life of massive stars. As the first conference in a long time that was specifically dedicated to Wolf-Rayet stars, an international workshop was held in Potsdam, Germany, from 1.-5. June 2015. About 100 participants, comprising most of the leading experts in the field as well as as many young scientists, gathered for one week of extensive scientific exchange and discussions. Considerable progress has been reported throughout, e.g. on finding such stars, modeling and analyzing their spectra, understanding their evolutionary context, and studying their circumstellar nebulae. While some major questions regarding Wolf-Rayet stars still remain open 150 years after their discovery, it is clear today that these objects are not just interesting stars as such, but also keystones in the evolution of galaxies. These proceedings summarize the talks and posters presented at the Potsdam Wolf-Rayet workshop. Moreover, they also include the questions, comments, and discussions emerging after each talk, thereby giving a rare overview not only about the research, but also about the current debates and unknowns in the field. The Scientific Organizing Committee (SOC) included Alceste Bonanos (Athens), Paul Crowther (Sheffield), John Eldridge (Auckland), Wolf-Rainer Hamann (Potsdam, Chair), John Hillier (Pittsburgh), Claus Leitherer (Baltimore), Philip Massey (Flagstaff), George Meynet (Geneva), Tony Moffat (Montreal), Nicole St-Louis (Montreal), and Dany Vanbeveren (Brussels).

Due to the severity of such events, it is of utmost importance to understand whether and how they change in re-sponse to evolving hydro-climatological, geo-physical and socio-economic conditions. These conditions jointly determine the magnitude, frequency, and impact of disasters, and are changing in response to climate change and human behavior. Therefore methods are need-ed for hazard and risk quantification accounting for the transient nature of hazards and risks in response to changing natural and anthropogenic altered systems. The purpose of this conference is to bring together researchers from natural sciences (e.g. hydrology, meteorology, geomorphology, hydraulic engineering, environmental science, seismology, geography), risk research, nonlinear systems dynamics, and applied mathematics to discuss new insights and developments about data science, changing systems, multi-hazard events and the linkage between hazard and vulnerabilities under unstable environmental conditions. Knowledge transfer, communication and networking will be key issues of the conference. The conference is organized by means of invited talks given by outstanding experts, oral presentations, poster sessions and discussions.

T1 - Clumping in hot-star winds : proceedings of an international workshop held in Potsdam, Germany, 18. - 22. June 2007 N2 - Stellar winds play an important role for the evolution of massive stars and their cosmic environment. Multiple lines of evidence, coming from spectroscopy, polarimetry, variability, stellar ejecta, and hydrodynamic modeling, suggest that stellar winds are non-stationary and inhomogeneous. This is referred to as 'wind clumping'. The urgent need to understand this phenomenon is boosted by its far-reaching implications. Most importantly, all techniques to derive empirical mass-loss rates are more or less corrupted by wind clumping. Consequently, mass-loss rates are extremely uncertain. Within their range of uncertainty, completely different scenarios for the evolution of massive stars are obtained. Settling these questions for Galactic OB, LBV and Wolf-Rayet stars is prerequisite to understanding stellar clusters and galaxies, or predicting the properties of first-generation stars. In order to develop a consistent picture and understanding of clumped stellar winds, an international workshop on 'Clumping in Hot Star Winds' was held in Potsdam, Germany, from 18. - 22. June 2007. About 60 participants, comprising almost all leading experts in the field, gathered for one week of extensive exchange and discussion. The Scientific Organizing Committee (SOC) included John Brown (Glasgow), Joseph Cassinelli (Madison), Paul Crowther (Sheffield), Alex Fullerton (Baltimore), Wolf-Rainer Hamann (Potsdam, chair), Anthony Moffat (Montreal), Stan Owocki (Newark), and Joachim Puls (Munich). These proceedings contain the invited and contributed talks presented at the workshop, and document the extensive discussions.
