When postcolonial studies meets media studies

This essay addresses (1) how postcolonial studies might inform and enrich media studies, especially as the latter is situated in the Communication discipline, and (2) how media studies may productively expand the terrain postcolonial studies, that thus far has been dominated by the fields of Literature and Comparative Literature. Focusing on, and challenging, issues such as the North Atlantic temporal logics that inform the received history of media studies, as well as contesting the narrow boundaries of literary studies for engaging in contemporary postcolonial media/ted cultures, this essay attempts to argue for the importance of postcolonial media studies.

出版企业人力资本运营的内容与方法

在知识经济时代,人力资本越来越起着主导作用。谁拥有高素质的人才,谁能高水平地运营人力资本,谁就能在未来的竞争中取胜。我国的出版企业是知识密集型企业,主要从事知识的生产、传播、积累,其有形资本甚少,更多的是人力资本、版权等无形资本,其价值创造主要依赖于管理者、员工智能的充分发挥。成功的出版企业资本运营首先必须着眼于人力资本运营。本文从方法论角度探讨出版企业人力资本的运营。

South African contributions to LGBTI education issues

ABSTRACT

South Africa stands out in the African region for its protection of lesbian, gay, bisexual, transgender and intersex (LGBTI) rights. This article examines South Africa’s contributions to local policy for LGBTIs and to work on LGBTI issues in education policy and education rights progress internationally. It also considers broader South African contributions to the theorisation of gender and sexuality. Data derive from an analysis of 102 interviews with key informants participating in high-level global networking for LGBTI students’ rights, and documentary analysis showing how stakeholders characterise South African contributions to transnational LGBTI education work. Informants identified how such contributions have a strong human rights emphasis, furthering post-colonial resistance to simplistic gender and sexuality classification schema imposed via imperial colonising dynamics. While South African work in this area has also promoted and facilitated research, it has at times been limited by ambivalence from its leadership. The nation’s early adoption of constitutional rights, relationship rights and educational equity provisions as acts of decolonisation contribute valuable African LGBTI work examples to the region. Their success encourages further funding for South-South transnational LGBTI education work.
