The purpose of this research lies in uncovering the participants emotions when watching a personalized advertisement on the social media Instagram. This is of use to the marketing and psychology research community to discover more on consumer behavior and the controversy between privacy concerns and usefulness of advertisement personalization. The research question reads: “Does the use of personalization on social media advertisements incite (1) a change in the emotional state and (2) recall capability of German Instagram users aged 18-30 that diverges from the psychophysiological parameters measured by exposing these users to the same advertisements without personalization?”
Psychophysiological tests are used in combination with two self reported questionnaires that assess the participants positive and negative effect and the recall and recognition differences between the group given personalized stimuli including the participants name, location, and activity and the one group given impersonalized ones. The sample consists of n=31 German-speaking participants between the age of 18 and 30.
The results, although not all of statistic relevancy of α=0,05, show a trend that personalized advertisements instigate more positive valence and activation as not personalized stimuli. No significant or trending difference was found to the recall and recognition capabilities of the two groups.
Non-fungible tokens (NFTs) have become a popular topic in the art world in recent years, with many museums and other cultural institutions exploring ways to incorporate them into their operations. The technology has the potential to revolutionize how museums conduct their internal business, how they collect, display, and preserve digital art, as well as how they enable engagement and an immersive experience for visitors. The research question of this paper thus addresses the significance of NFTs in the evolution of museum practices.
Using a qualitative research approach, eleven museum experts were interviewed in semi-structured interviews about the evolution, the impact and the viability of NFTs. The results of the content analysis were then summarized, interpreted, and discussed in relation to the theoretical framework, and were subsequently converted into general conclusions for the museum sector. The process resulted in relevant information about the opportunities, challenges, and strategy of museums for implementing NFTs in museum practices.
This thesis examines how financial institutions can address outcomes of the global financial crisis (GFC) such as mistrust of customers and ambitious requirements of regulations such as Basel III. Moreover, the market is facing a dramatic sociocultural change which creates the necessity to realign retail banks’ strategies. It will be outlined why social media is an important trend for the financial sector and which methods can be used to achieve a competitive advantage through customer-centricity. On the one hand the financial sector will be analysed to determine which of Porter’s five forces are shaping it. On the other hand, it will be shown how social media can be used to achieve a competitive advantage. This thesis will find out that social media is an important medium for retail banks to gain back customers’ trust in financial institutions and to focus on the customers’ needs. By engaging customers on social media platforms such as Facebook or Twitter, financial institutions can even create value beyond financial products and increase their innovative drive. Best practice examples of Banks such as CBA, ING Direct, Wells Fargo, and ICICI prove that. The implications are that social media gives customers the power to shape the bank of tomorrow and in turn banks can gain valuable insights into customers’ needs. Financial products and services will make more use of social media platforms and increase customers’ engagement through sharing, commenting and liking.
Relevance: Political and private initiatives call for more female founders in start-ups as well as entrepreneurship but with regard to academic research not many studies focused yet on interdisciplinary studies on especially female start-up founders. There is more need to understand the topic to further encourage female founders.
Research question: The research question of this thesis is analysing what kind of patterns can be seen in the entrepreneurial, sociocultural and psychological profile of female founders compared in start-up ecosystems of three different countries, namely Germany, France and Israel?
Approach: I conducted 21 interviews, seven for each city, with a semi-structured guideline focusing on the entrepreneurial, sociocultural and psychological profile. The interviews were transcribed and afterwards analysed by combining the different profiles to find possible patterns. In a final step the observations from each country were compared to one another.
Findings: There are several possible patterns for each country evident. However, a cross-cultural comparison was made difficult by the heterogeneous groups of respondents. It was nevertheless possible to conclude on four crosscultural hypotheses: 1) Female entrepreneurs prefer to work first before starting their own business; 2) The female entrepreneurial profile is risk-taking, purpose-driven, innovative and autonomous; 3) Immigration has a positive effect on the intention to start a business; 4) The majority of female entrepreneurs have a higher education and come from a middle to upper social class.
Digitalisation is shaping a new consumption era characterised by high connectivity, mobility and a broad range of easily accessible information on products, prices and alternatives. As a result, it becomes more difficult than ever to understand modern consumers along their complex and dynamic path to purchase. However, mobile data about consumers’ behaviour captured on their phone has high potential for facing this challenge. Yet, there is no solution on how to use this data to follow the consumers on their mobile devices. This thesis proposes a first approach on how mobile data collected with smartphone sensing technology can be analysed to assess mobile consumer behaviour along their customer journey. Based on current practices in customer journey analytics, a mobile customer journey model is developed and three analysis concepts are created, which are implemented in an explorative analysis. The results show that mobile sensing data presents a great opportunity for analysing mobile behaviour in three main research areas: examining the touchpoint performance of a brand across mobile apps, describing different target groups by their smartphone usage behaviour and deriving real customer journeys on users’ devices. Nonetheless, further exploration is necessary to unlock the full potential of mobile data in customer journey analytics.
As technology advances, the services offered by libraries and the roles of
librarians continue being reconsidered. This paper describes the traditional
model and development of liaison and embedded librarians, examines the
online visibility of liaison librarians and their services in an embedded sense,
especially regarding instruction, of selected Canadian Academic Libraries, and
provides a short view to German libraries and their subject librarians.
It has been shown that even if not clearly a development of liaison librarians to
certain embedment is emphasized for each library, it at least evolves to a usercentered
approach and a preference to stronger collaborations. The selected
libraries seek to broaden their scope of partnerships. In which deepness it is
realized, lastly depends on the willingness of both participators and capacities.
Libraries have stated their flexibility in various ways and are ready to step in at
the point of need. The one closest to embedded services is the instruction of
information literacy as its effectiveness requests a longer relationship in order to
flourish. Nevertheless research support in Health Sciences obviously has
become an integral part.

As the information era progresses, the sheer volume of information calls for sophisticated retrieval systems. Evaluating them holds the key to ensuring the reliability and relevance of retrieved information. If evaluated with renowned methods, the measured quality is generally presumed to be dependable. That said, it is often forgotten that most evaluations are only snapshots in time and the reliability might be only valid for a short moment. Further, each evaluation method makes assumptions about the circumstances of a search and thereby has different characteristics. Achieving reliable evaluation is critical to retain the aspired quality of an IR system and maintain the confidence of the users. Therefore, we investigate how the evaluation environment (EE) evolves over time and how this might affect the effectiveness of retrieval systems. Further, attention is paid to the differences in the evaluation methods and how they work together in a continuous evaluation framework. A literature review was conducted to investigate changing components which are then modeled in an extended EE. Exemplarily, the effect of document and qrel updates on the effectiveness of IR systems is investigated through reproducibility experiments in the LongEval shared task. As a result, 11 changing components together with initial measures to quantify how they change are identifed, the temporal consistency of five IR systems could precisely be quantifed through reproducibility and replicability measures and the findings were integrated into a continuous evaluation framework. Ultimately, this work contributes to more holistic evaluations in IR.
The goal of this work is to detect "gender biases" in the communication of users of Subreddits on the platform Reddit. The analysis is carried out for eleven selected Subreddits. Furthermore, an attempt is made to identify different user types with the help of a k-means clustering and also to analyze "gender biases" in their communication. Based on the aggregated datasets, fasttext Word Embedding models are trained to identify terms that show high semantic relatedness in terms of cosine similarity of their word vectors with selected feminine and masculine terms.
To this end, the terms are analyzed for sentiment using the NRC-VAD Lexicon and tested for statistically significant differences. In addition, the Word Embedding Association Test (WEAT) is performed to check for subliminal associations. In relation to the considered text corpus, it is essentially observed that women are frequently associated with adjectives that associate them with appearances,
childbearing abilities or adaptability also in relation to the family. In contrast, men are associated with and measured by adjectives that refer to their prestige, strengths and weaknesses, career or physical characteristics.
