Insbesondere wegen dem oft zitierten Fachkr{\"a}ftemangel in naturwissenschaftlichen und technischen Berufen ist eine Motivationssteigerung in naturwissenschaftlichen Unterrichtsf{\"a}chern wichtig. Denn trotz Leistungssteigerungen in internationalen Vergleichstests m{\"o}chten in Deutschland deutlich weniger Sch{\"u}ler*innen einen solchen Beruf ergreifen als in anderen Industriestaaten. Daher gilt es, m{\"o}glichst fr{\"u}h Sch{\"u}ler*innen f{\"u}r naturwissenschaftlich-technische F{\"a}cher zu begeistern und insbesondere im regelrecht verhassten Physikunterricht flow-Erleben zu erzeugen. Im Rahmen dieser Arbeit wird das flow-Erleben von Studierenden in klassischen Laborexperimenten und FELS (Forschend-Entdeckendes Lernen mit dem Smartphone) als Lernumgebung untersucht. FELS ist eine an die Lebenswelt der Sch{\"u}ler*innen angepasste Lernumgebung, in der sie mit Smartphones ihre eigene Lebenswelt experimentell untersuchen. Es zeigt sich, dass sowohl klassische Laborexperimente als auch in der Lebenswelt durchgef{\"u}hrte, smartphonebasierte Experimente flow-Erleben erzeugen.

While envy has been considered a status-related emotion and is likely to be experienced in response to perceiving another's higher status, there is a lack of research exploring how status perceptions influence the emergence of envy on SNSs. This is important because SNSs typically quantify social interactions and reach with metrics that indicate users' relative rank and status in the network. To understand how status perceptions impact SNS users, we introduce a new form of metric-based digital status rooted in SNS metrics that are available and visible on a platform. Drawing on social comparison theory and status literature, we conducted an online experiment to investigate how different forms of status contribute to the proliferation of envy on SNSs. Our findings shed light on how metric-based digital status influences feelings of envy on SNSs. Specifically, we could show that metric-based digital status impacts envy through increasing perceptions of others' socioeconomic and sociometric statuses. Our study contributes to the growing discourse on the negative outcomes associated with SNS use and its consequences for users and society.}, language = {en} } @techreport{AndresBruttelFriedrichsen2021, type = {Working Paper}, author = {Andres, Maximilian and Bruttel, Lisa Verena and Friedrichsen, Jana}, title = {The Leniency Rule Revisited: Experiments on Cartel Formation with Open Communication}, series = {CEPA Discussion Papers}, journal = {CEPA Discussion Papers}, number = {24}, issn = {2628-653X}, doi = {10.25932/publishup-49169}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-491696}, pages = {62}, year = {2021}, abstract = {The experimental literature on antitrust enforcement provides robust evidence that communication plays an important role for the formation and stability of cartels.

We study one particular context in which ignorance can be beneficial: iterated strategic interactions in which voluntary cooperation may be sustained into the final round if players voluntarily forego knowledge about the time horizon. We experimentally examine this option to remain ignorant about the time horizon in a finitely repeated two-person prisoners' dilemma game. We confirm that pairs without horizon knowledge avoid the drop in cooperation that otherwise occurs toward the end of the game. However, this effect is superposed by cooperation declining more rapidly in pairs without horizon knowledge during the middle phase of the game, especially if players do not know that the other player also wanted to remain ignorant of the time horizon.}, language = {en} } @phdthesis{Wrzus2008, author = {Wrzus, Cornelia}, title = {Similarity in personal relationships : associations with relationship regulation between and within individuals}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus-20158}, school = {Universit{\"a}t Potsdam}, year = {2008}, abstract = {People engage in a multitude of different relationships. Relatives, spouses, and friends are modestly to moderately similar in various characteristics, e.g., personality characteristics, interests, appearance. The role of psychological (e.g., skills, global appraisal) and social (e.g., gender, familial status) similarities in personal relationships and the association with relationship quality (emotional closeness and reciprocity of support) were examined in four independent studies. Young adults (N = 456; M = 27 years) and middle-aged couples from four different family types (N = 171 couples, M = 38 years) gave answer to a computer-aided questionnaire regarding their ego-centered networks. A subsample of 175 middle-aged adults (77 couples and 21 individuals) participated in a one-year follow-up questioning. Two experimental studies (N = 470; N = 802), both including two assessments with an interval of five weeks, were conducted to examine causal relationships among similarity, closeness, and reciprocity expectations. Results underline the role of psychological and social similarities as covariates of emotional closeness and reciprocity of support on the between-relationship level, but indicate a relatively weak effect within established relationships. In specific relationships, such as parent-child relationships and friendships, psychological similarity partly alleviates the effects of missing genetic relatedness. Individual differences moderate these between-relationship effects. In all, results combine evolutionary and social psychological perspectives on similarity in personal relationships and extend previous findings by means of a network approach and an experimental manipulation of existing relationships. The findings further show that psychological and social similarity have different implications for the study of personal relationships depending on the phase in the developmental process of relationships.}, language = {en} } @inproceedings{HaaseMatthiesenSchueffleretal.2020, author = {Haase, Jennifer and Matthiesen, Julia and Sch{\"u}ffler, Arnulf and Kluge, Annette}, title = {Retentivity beats prior knowledge as predictor for the acquisition and adaptation of new production processes}, series = {Proceedings of the 53rd Hawaii International Conference on System Sciences}, volume = {53}, booktitle = {Proceedings of the 53rd Hawaii International Conference on System Sciences}, publisher = {Western Periodicals Co.}, address = {North Hollywood, Calif.}, doi = {10125/64331}, pages = {4797 -- 4805}, year = {2020}, abstract = {In the time of digitalization the demand for organizational change is rising and demands ways to cope with fundamental changes on the organizational as well as individual level.

This particularly challenges knowledge management, aiming for the assignment of ideal manifestations of influence factors on knowledge transfers to a certain task. Faced with first attempts of knowledge transfer-based process improvements [1], this paper continues research about the quantitative examination of knowledge transfers and presents a ready-to-go experiment design that is able to examine quality of knowledge transfers empirically and is suitable to examine knowledge transfers on a quantitative level. Its use is proven by the example of four influence factors, which namely are stickiness, complexity, competence and time pressure.}, language = {en} }
