Monday, June 21th, 2021. Katharina Baum and Prof. Dr. Hanna Krasnova, in collaboration with Dr. Stefan Meissner of the Norwegian School of Economics conducted a study on the role of partisan self-interest in the support for regulation of online targeted political advertising in the United States. With this kind of advertising, political parties target messages to voters based on personal data on platforms such as Facebook. The researchers find that supporters of both the Republican and Democratic parties believe that voters of the opposing party are more easily influenced by such advertising. “This implies that voters of both parties think the other party benefits more from online targeted political advertising, as they assume the opposing party can more easily persuade their supporters to vote for them”, Katharina Baum explains. The results further show that this belief is causally related to the support for the regulation of online targeted political advertising. When being informed that online targeted political advertising has benefited Republicans, but not Democrats, in the past, Republicans then report lower levels of support for regulation. The authors conclude that calls for stricter regulation of online targeted political advertisement also depend on how people think about the effect of online targeted political advertising on others. The study, "Partisan self-interest is an important driver for people's support for the regulation of targeted political advertising," by Katharina Baum, Stefan Meissner, and Hanna Krasnova, was published in the journal PLOS ONE.
Thursday, June 3rd, 2021. Today, our chair member Safa’a AbuJarour defended her dissertations to earn her doctoral degree.

Monday, September 19, 2016: Spurred by the war in Syria, continuing violence in Iraq and Afghanistan, refugee crisis has swept the European Region. Over 1.3 million asylum applications have been submitted across countries of the European Union, with Germany attracting the highest number of asylum seekers. These developments pose significant challenges. With local population caught by surprise and unfamiliar with the social norms and cultural practices of the incoming refugees, there is a pressing need to bring both parties together by enhancing intercultural awareness.
As part of the brand-new course “Online Social Media Marketing” offered by Prof. Dr. Hanna Krasnova, our students were given the opportunity to design a real social media campaign for this highly pressing cause. Supervised by our research associate Safa’a AbuJarour, a group of three students - Farina Hoffmeier, Lena Jung, Marianna Merseburger - have done an amazing job!
Their campaign aimed at promoting a positive image of refugees in Germany and changing public perceptions associated with the term “refugee”. This is how the three girls described the intention behind their project: "The word refugee is often associated with negative perceptions in our society. People often think only of problems, violence, death, integration challenges. They often forget about the real people, their personalities and the unique ways they can contribute to our evolving culture. We would like to open the curtain. We would like to give local population a chance to see and experience who the refugees are, their interests, dreams and ambitions. The more we know about each other, the easier the integration process is going to get! We are so enthusiastic about the impact our work might have”!
Based on the interviews with seven refugees in Berlin and Brandenburg Farina Hoffmeier, Lena Jung, Marianna Merseburger have been able to get more insights into the daily lives of refugees in Germany, their hopes and their aspirations. Their conclusion: "Refugees - They are just like us! Just awesome! We laugh about the same things and we do the same things in our free time. It should be easier to find a way to do it together!"

Tuesday, July 12, 2016: In this semester's Data Science class we organized a competition among the student's projects, which had to be defended in front of independent experts. The best projects were awarded with certificates. The task was to apply the skills and tools provided in class to interesting fields, preparing an insightful presentation of knowledge extracted with the use of R. The students extracted raw data and processed it with only the use of R software. In the end, we gained quite interesting insights!
We had presenations on the following topics:
Saturday, July 9, 2016: As part of our research interest, our team member Safa’a AbuJarour, who is a co-founder of the initiative Place4Refugees, in cooperation with our students in the course Online and Social Media Marketing, who initiated the project “Who are the Refugees”, have co-organized an event for the refugees to celebrate the end of Ramadan feast in Berlin.
The main goal of this celebration is to share the refugees in their celebration of one of the most important occasions for them. We celebrated this event in a social gathering, in which they could feel home and reduce their homesickness. Additionally, it was an excellent occasion to gather locals with the newcomers to support the integration process between both sides.
To sponsor this event, our team member and students initiated a crowdfunding project to engage all interested parties to make the success of this event.
Moreover, this event attracted significant media attention, where our team member Safa’a AbuJarour was interviewed to talk about this project. The interview on RBB Info-Radio can be found here.
The event was successful from the refugees and the locals’ point of views. We distributed gifts for kids and oriental sweets for everyone. Several social games were also organized for the kids and social discussions took place for adults. By the end of the event, we were able to make our gusts happy and to make ourselves proud of the successful event.
Thanks to everyone who supported us making this event such a successful one!
Tuesday, June 21, 2016: Our chair would like to congratulate our team member Helena Wenninger for successfully defending her PhD thesis about the influence of social networking sites (SNS) on their members at the University of Darmstadt. We are proud of her achievement, and wish her the best for her future professional as well as personal life.
In her dissertation, Helena focused on the differentiation of various usage patterns and social mechanisms taking place on these digital platforms. A diary study with teens suggests that directed communication features like private messages or the “like”-button to increase belongingness with others. On the other hand, social comparison processes following the consumption of social information on SNSs have been linked to detrimental outcomes like envy feelings. Overall, results show the importance of distinguishing usage behaviors due their potential to explain controversial outcomes of SNSs usage.
Friday, June 10, 2016: Our chair was honored to welcome one of the most influential researchers in the field of IS in the period of 2nd of June to 10th of June 2016.

Abstract: Coined as “phubbing”, excessive use of smartphones in the romantic context has been shown to represent a barrier to meaningful communication, causing conflict, lowering relationship satisfaction, and undermining individual well-being. While these findings project a dire picture of the future of romance, the mechanisms behind the detrimental influence of partner phubbing on relationship-relevant markers are still little understood. Considering prior evidence that partner phubbing leads to the loss of exclusive attention towards the other party, we argue that these are rather the feelings of jealousy partner phubbing is triggering that are responsible for the negative relational outcomes.
Based on the analysis of qualitative and quantitative responses from “generation Y” users, we find that partner phubbing is associated with heightened feelings of jealousy, which is inversely related to couple’s relational cohesion. Moreover, jealousy plays a mediating role in the relationship between partner’s smartphone use and relational cohesion, acting as a mechanism behind this undesirable link. Challenging the frequently promoted euphoria with regard to permanent “connectedness”, our study contributes to a growing body of IS research that addresses dark sides of information technology use and provides corresponding implications for IS practitioners.

Monday, April 11, 2016: How do you respond to a negative review in the Sharing Economy? Olga Abramova and Prof. Dr. Hanna Krasnova discuss the role of three critical response strategies to negative reviews in the Sharing Economy in their new publication in the Swiss Journal of Business Research and Practice “Die Unternehmung” ( 70. Jg.,1/2016).
Recognizing the harmful effect of negative reviews on the reputation of the hosts as well as a subjective nature of the travel experience judgements, accommodation sharing platforms, like Airbnb, have introduced the response option, empowering hosts with the voice to deny, present an excuse, or at least apologize for the subject of the criticism. However, the effects of different response strategies on the impression of guests regarding the host and, above all, guests’ willingness to rent a specific accommodation in the sharing setting remain unclear. To fill this gap, this study focuses on understanding the impact of different response strategies utilizing experimental methods. Our investigation shows that when the subject of complaint is controllable by a host, only the “confession / apology” strategy can improve the impression of guests regarding the host and enhance guests’ willingness to rent, compared to the absence of response. However, when the subject of criticism is beyond the control of the host, both “confession / apology” and “excuse” have positive influence on the impression and also guests’ willingness to rent. At the same time, “denial” strategy appears ineffective in both controllable and uncontrollable contexts we tested.
Monday, April 11, 2016: The society is nowadays concerned about the refugees’ situation in Germany; therefore, Safa’a AbuJarour and Prof. Dr. Hanna Krasnova would like to bridge the gap between the society and the newcomers to help both sides gain the best out of the current situation, namely, turn the crisis into an opportunity. Safa’a has been achieving this goal in practice due to her understanding of both cultures and her involvement in the refugees’ situation since the start of the crisis in Berlin. Their plan now is to apply scientific research methods to this situation to come up with best practices and recommendation to optimize it, and to investigate how stress and social support affect the overall well-being of the refugees.
Considering the novelty and unprecedented scale of the refugee crisis, there are little research insights on how the technology can be successfully used to alleviate human suffering, improve refugees’ chances for integration, and enhance acceptance of refugees by the hosting population. At the same time, during her engagement, Safa’a AbuJarour recognized the potential of Social Networks to bring the volunteers together to solve the problem of finding places for the refugees. Therefore, she created a Facebook group that has meanwhile around 4000 members. In the process, she realized that not only the volunteers use this group, but also the refugees themselves. Hence, she managed with the team of volunteers to extend their involvement and create a new website, Place4Refugees.de, that serves the needs of the volunteers and the refugees at the same time.
During the previous months, we have been gathering many insights about how the refugees use their smartphones and Social Networks to deal with the new situation in Germany. These learnings can be applied to increase the efficiency of online language classes for the refugees. Enhancing the user’s expedience of Open Education and adapting Open Educational approaches according to the cultural differences of the newcomers can have a considerable impact on their success and value. For instance, based on the culture of the refugees from Middle East, it is expected that social-oriented Open Educational classes will have a huge advantage over normal Open Educational classes.
We will publish the initial results of our current research on our website soon … stay tuned.
