This Toolbox for gender-neutral, diversity-oriented institutional communication (D. 5.4) is submitted by RUB as part of Work Package 5 – Ensure a sustainable and cultural change by establishing a gender and diversity-friendly environment of the RESET project. This toolbox is the output of Task 5.4 – Promoting a unique standard of gender neutral, non-discriminatory, positive forms of communication. The toolbox builds on the insights and achievements that are reflected in the Guidelines for gender-sensitive communication in research and academia (2021) of the project SUPERA – Supporting the Promotion of Equality in Research and Academia. Additionally, this toolbox enriches the focus on gender-sensitive communication with the notion of gender-inclusive forms of communication as well as an intersectional perspective on further dimensions of diversity. For this, the Toolbox contains with a conceptual framework, that has a purpose to provide valuable information and knowledge around the necessity of gender-neutral, gender-sensitive as well as diversity-oriented forms of communication. Here, RESET’s intersectional perspective, and its understanding of diversity in the context of HEIs are explained. Information on social psychological and socio-linguistic aspects of communication are interpreted in relation to gender and diversity. Against these backgrounds the opportunities and challenges of visual aspects of communication are reflected. Part B contains the tools that have been developed in the context of the toolbox-creation, aligned with the conceptual framework, and based on institutional queries, interviews, and discussions within RESET consortium. They are meant to provide a starting point for making communication at our universities more inclusive, both in terms of gender diversity and other diversity factors. The Toolbox is a work-in-progress and closely interwoven with the ongoing work of RESET project. It will be enriched as the project evolves. At this stage, the toolbox has a strong focus on the aspect of gender-inclusive communication. In the future, it is going to entail more tools that emphasize the diversity aspect to a greater extent and that are going to be co-designed with our communities at our universities, to create safe and diversity friendly environments.
