I would love to read more about new dimensions of diversity, especially looking at deep-level diversity. Intrapersonal diversity and its role should also be highlighted more.
I think the most important topic is to discuss the relationship between diversity and integration. With the mobility of people, learning to live and work with others is a huge current challenge.
Diversity and the problems of belonginess for people in transition - where are the lines drawn or the aspirational boundaries subverted. Why is the process of seeking the norm often acknowledged with a lens of culture differences.
I would, heartily, like to read more on discourse of diversity. Litvin's article (1997) on the topic was eye-opening for me. More can be said on the topic, such as how our field embraced the term, how it evolved, what do we really understand when we talk about diversity and on what assumptions we understand as it is.
I want to read about the relationship between the urban form and the collective public deliberations in asserting its order and how can we gain experiences from the unplanned urbanism for our contemporary cities.
