(Conference or Workshop Paper published in Proceedings)
Gendered voice based on pitch is a prevalent design element in many contemporary Voice Assistants(VAs) but has shown to strengthen harmful stereotypes. Interestingly, there is a dearth of research that systematically analyses user perceptions of different voice genders in VAs. This study investigates gender-stereotyping across two different tasks by analyzing the influence of pitch (low, high) and gender (women, men) on stereotypical trait ascription and trust formation in an exploratory online experiment with 234 participants. Additionally, we deploy a gender-ambiguous voice to compare against gendered voices. Our findings indicate that implicit stereotyping occurs for VAs. Moreover, we can show that there are no significant differences in trust formed towards a gender-ambiguous voice versus gendered voices, which highlights their potential for commercial usage. |

In this paper, we examine if a slight behavioural modification has an influence on discrimination. Specifically, we use a field experiment based on emails to observe if persistence increases the chances of joining a social group. We find that native- or foreign-sounding names are equally successful when being persistent. However, non-persistent individuals with foreign-sounding names suffer from discrimination. The results show that persistent individuals can be especially interesting in the context of field experiments. |

Lauren Howe, Jon Michael Jachimowicz, Jochen Menges, Your job doesn't have to be your passion, Harvard Business Review, 2021. (Journal Article)
The pandemic has been a wake-up call for a lot of people, causing us to reevaluate our lives and our careers. It’s natural to think: “If I’m going to spend so much time at work, I might as well do something I’m passionate about.” But there are also benefits to thinking about it differently: Instead of pursuing a career based on your passion, how can you career be a conduit to your passion?
Pursuing a passion outside of work can be less risky. And some research suggests transforming hobbies into work can actually undermine your enjoyment of these activities. Instead, look for a job that will give you the resources - time, money, and energy - to pursue your passion.
If time is your scarcest resource, look for a job that offers schedule flexibility so that you can structure your work around your passions.
If money is the issue, look for a job that allows you to pay for the life you want to lead.
When it comes to energy, don’t think of your passion as something that provides fuel to energize you for work. Instead, look at your job as giving you the security and income to pursue your passion. |

Das Core-Portfolio soll zum grossen Teil den Markt spiegeln, also eine Art Weltaktien-Portfolio sein. Die Anlagen in diesem Portfolio sollen eher selten umgeschichtet werden. Die Portfolio-Zusammensetzung sollte relativ konstant bleiben. Da es eine Art Weltaktien-Portfolio abbildet, bietet es am meisten Diversifikation, was die Kursschwankungen mindern sollte.

Cornel Nesseler, Carlos Gomez-Gonzalez, Thadeu Gasparetto, Head coach tenure in college women’s soccer. Do race, gender, and career background matter?, Sport in Society, Vol. 24 (6), 2021. (Journal Article)
This study aims to analyse the tenure of head coaches in college women’s soccer in the USA and puts the focus on the influence of race and gender. The analysis includes individual characteristics of coaches (educational and professional background), team performance, institutional characteristics, and geographical differences (at the state level) from 1977 until 2015. The main results show that African American coaches and women have a significantly shorter tenure in these college institutions. Other factors related to the background of coaches and the characteristics of institutions also play a significant role. The findings are relevant for coaches from minority groups and athletic departments, who are interested in equity in sport. Future research may use an alternative approach to investigate the causes of tenure disparity in college women’s soccer. |

Philippe Schmidli, Digitale Unterstützung des Online-Kundenfeedback-Managements; Eine empirische Untersuchung im Bereich Gastronomie, University of Zurich, Faculty of Business, Economics and Informatics, 2021. (Bachelor's Thesis)
The popularity of the Internet and the possibility for consumers to share their opinions and experiences with products and services online has a significant influence on consumer behavior. Increasing numbers of consumers are using online consumer reviews to make their purchase decisions. This consumer trend has attracted the attention of companies that want to make profitable use of this information, which increasingly leads them to new challenges. In this thesis, online customer feedback management in the hospitality industry was examined. The aim of this work is to show the challenges of online customer feedback management from the perspective of restaurant managers and examine the extent to which those challenges can be addressed with artificial intelligence. For this purpose, interviews were conducted with managers from different restaurant businesses. The results show that AI-based IT solutions can provide support for both the analysis of and response to consumer reviews. However, AI support is limited by the lack of available information, the characteristics of the review sites, and the current values and norms of society. |

The goal of this thesis is to identify the challenges which occur for Hotels during the online feedback management process. This leads to the following research question: Which challenges occur from online feedback management from the viewpoint of hotel owners and managers?
A qualitative analysis was carried out to answer this research question. The qualitative analysis shows that the biggest challenges occur while drafting answers. In addition a second research question is posed: Which challenges can be addressed with AI technologies? How challenging are technical solutions to these challanges? In this thesis several solutions to the identified challenges are proposed. |

Dominic Schmidli, Face Recognition Aspects with DNNs; An Experimental and Reproducible Research Survey, University of Zurich, Faculty of Business, Economics and Informatics, 2021. (Bachelor's Thesis)
Face recognition has become an indispensable part of life in today's world. In addition to unlocking mobile devices, it can also be used in public safety applications. Earlier, face recognition was accomplished using traditional algorithms. Today, face recognition has been dominated by deep learning, and deep convolutional neural networks can achieve impressive results. Unfortunately, these results can rarely be reproduced due to missing experimental details. The goal of this work is to compare state-of-the-art deep neural networks with respect to different aspects of face variations. For this purpose, four open-source networks from ArcFace and one from VGGFace2 were used. Experiments are performed on different databases to evaluate the influence of face variations. The results show that deep learning methods clearly outperform traditional face recognition algorithms, and the training database plays a crucial role in their performance. Most of the networks can handle occlusion and illumination well, but poses and facial expressions may still cause problems. Finally, recognizing faces at longer distances requires further improvement. |

Moritz Jenny, Reconstructing Office Environments in VR from Point Cloud Data Sets, University of Zurich, Faculty of Business, Economics and Informatics, 2021. (Bachelor's Thesis)
Virtual reality enables a far more immersive experience than a visualization on a 2D screen. Moreover, the representation of data distributed over the three spatial dimensions can be perceived in a very intuitive way. The goal of this work is to illustrate the representation of segmented point clouds as well as to present possibilities for interactions
with point clouds in VR. Furthermore, the process which integrates the raw data of a 3D scan into a VR application shall be automated. In particular, the immersive experience is enhanced by having the user physically located in the corresponding space from which their scanned data is viewed. The final result is achieved by training a neural network with a dataset that includes scans of office spaces. After preprocessing
the data from a point cloud scan of an office, it can be segmented using the trained network. Finally, the segmented data is rendered in a game engine so that it can be viewed and interacted with in virtual reality. Thus, the segmentation can be visualized and serves as the basis for interactive elements that creates an inspiring or game-like experience. |
