Gender Theory in Troubled Times


 
Theorizing gender is more urgent and highly political than ever before. These are times, in many countries, of increased visibility of women in public life and high-profile campaigns against sexual violence and harassment. Challenges to fixed, traditional gender norms have paved the way for the recognition of gay marriage and gender recognition acts allowing people to change the gender assigned to them at birth. Yet these are also times of religious

Let me draw you a map: knowledge management from "two completely different streams of thought"

Let me draw you a map: knowledge management from "two completely different streams of thought" HeavyHead, Danielle; Greenshields, Mary This paper represents the results of a conversation between Adrienne Heavy Head, the creator and manager of the Blackfoot Digital Library (BDL), at the University of Lethbridge in Alberta, Canada, and Mary Greenshields, a new librarian in Alberta. The aim of the conversation was for Mary, a settler living in traditional Blackfoot Territory, to learn about the creation and maintenance of the BDL and to gain insight into the organization, access, and classification of information within the library as a real-life example of some of the Protocols suggested by the Canadian Federation of Library Associations. Adrienne and Mary hope that this conversation will help librarians to better understand knowledge management from a Blackfoot perspective and might inspire librarians to start and continue such conversations with the Indigenous peoples upon whose lands their libraries rest.
