Lay Summary Active use of social networking sites (SNSs) has long been assumed to benefit users' well-being. However, this established assumption is increasingly being challenged, with scholars criticizing its lack of empirical support and the imprecise conceptualization of active use. Nevertheless, with great diversity among conducted studies on the hypothesis and a lack of causal evidence, a final verdict on its viability is still pending. To contribute to this ongoing debate, we conducted a week-long experimental investigation with 381 adult Instagram users. Specifically, we tested how posting pictures on Instagram affects different aspects of well-being. The results of this study depicted a positive effect of posting Instagram pictures on users' experienced positive emotions but no effects on other aspects of well-being. The findings broadly align with the recent criticism against the active use hypothesis and support the call for a more nuanced view on the impact of SNSs on users.}, language = {en} } @inproceedings{KrasnovaGundlachBaumann2022, author = {Krasnova, Hanna and Gundlach, Jana and Baumann, Annika}, title = {Coming back for more}, series = {PACIS 2022 proceedings}, booktitle = {PACIS 2022 proceedings}, publisher = {AIS Electronic Library (AISeL)}, address = {[Erscheinungsort nicht ermittelbar]}, isbn = {9781958200018}, year = {2022}, abstract = {Recent spikes in social networking site (SNS) usage times have launched investigations into reasons for excessive SNS usage. Extending research on social factors (i.e., fear of missing out), this study considers the News Feed setup. More specifically, we suggest that the order of the News Feed (chronological vs. algorithmically assembled posts) affects usage behaviors. Against the background of the variable reward schedule, this study hypothesizes that the different orders exert serendipity differently. Serendipity, termed as unexpected lucky encounters with information, resembles variable rewards. Studies have evidenced a relation between variable rewards and excessive behaviors. Similarly, we hypothesize that order-induced serendipitous encounters affect SNS usage times and explore this link in a two-wave survey with an experimental setup (users using either chronological or algorithmic News Feeds). While theoretically extending explanations for increased SNS usage times by considering the News Feed order, practically the study will offer recommendations for relevant stakeholders.}, language = {en} } @inproceedings{KoesterBaumannKrasnovaetal.2020, author = {K{\"o}ster, Antonia and Baumann, Annika and Krasnova, Hanna and Avital, Michel and Lyytinen, Kalle and Rossi, Matti}, title = {Panel 1: to share or not to share}, series = {Proceedings of the 28th European Conference on Information Systems (ECIS): ECIS 2020 Panels}, booktitle = {Proceedings of the 28th European Conference on Information Systems (ECIS): ECIS 2020 Panels}, publisher = {AIS Electronic Library (AISeL)}, address = {[Erscheinungsort nicht ermittelbar]}, year = {2020}, abstract = {Data sharing requires researchers to publish their (primary) data and any supporting research materials. With increased attention on reproducibility and more transparent research requiring sharing of data, the issues surrounding data sharing are moving beyond whether data sharing is beneficial, to what kind of research data should be shared and how. However, despite its benefits, data sharing still is not common practice in Information Systems (IS) research. The panel seeks to discuss the controversies related to data sharing in research, specifically focusing on the IS discipline. It remains unclear how the positive effects of data sharing that are often framed as extending beyond the individual researcher (e.g., openness for innovation) can be utilized while reducing the downsides often associated with negative consequences for the individual researcher (e.g., losing a competitive advantage). To foster data sharing practices in IS, the panel will address this dilemma by drawing on the panelists' expertise.}, language = {en} } @article{ZahediOeznurAkalinLawrenceetal.2022, author = {Zahedi, Anoushiravan and {\"O}znur Akalin, Renin and Lawrence, Johanna E. and Baumann, Annika and Sommer, Werner}, title = {The nature and persistence of posthypnotic suggestions' effects on food preferences}, series = {Frontiers in nutrition : FNUT}, volume = {9}, journal = {Frontiers in nutrition : FNUT}, publisher = {Frontiers Media}, address = {Lausanne}, issn = {2296-861X}, doi = {10.3389/fnut.2022.859656}, pages = {6}, year = {2022}, abstract = {Food preferences are crucial for diet-related decisions, which substantially impact individual health and global climate. However, the persistence of unfavorable food preferences is a significant obstacle to changing eating behavior. Here we explored the effects of posthypnotic suggestions (PHS) on food-related decisions by measuring food choices, subjective ratings, and indifference points. In Session 1, demographic data and hypnotic susceptibility of participants were assessed. In Session 2, following hypnosis induction, PHS aiming to increase the desirability of healthy food was delivered. Afterward, a task set was administrated twice, once when PHS was activated and once deactivated. The order of PHS activation was counterbalanced across participants. The task set included a liking-rating task for 170 pictures of different food items, followed by an online supermarket where participants were instructed to select enough food for a fictitious week of quarantining from the same item pool. After 1 week, Session 3 repeated Session 2 without hypnosis induction in order to assess the persistence of PHS. The crucial dependent measures were food choices, subjective ratings, and the indifference points as a function of time and PHS condition.}, language = {en} } @article{SpiekermannKrasnovaHinzetal.2022, author = {Spiekermann, Sarah and Krasnova, Hanna and Hinz, Oliver and Baumann, Annika and Benlian, Alexander and Gimpel, Henner and Heimbach, Irina and Koester, Antonia and Maedche, Alexander and Niehaves, Bjoern and Risius, Marten and Trenz, Manuel}, title = {Values and ethics in information systems}, series = {Business \& information systems engineering}, volume = {64}, journal = {Business \& information systems engineering}, number = {2}, publisher = {Springer Gabler}, address = {Wiesbaden}, issn = {2363-7005}, doi = {10.1007/s12599-021-00734-8}, pages = {247 -- 264}, year = {2022}, language = {en} }
