  • LAAM12 Researching Human Rights

    Human Rights are increasingly relevant across the range of public policy as well as in the work of third sector and business. Global systems of governance, policy, law and economy require participants who are skilled in human rights as well as the techniques of Human Rights Research and application. The module will focus on the skills necessary to effectively research human rights contemporary issues, and on developing the attributes of assessment, evaluation and communication necessary to make use of human rights research outcomes in the context of the public, private or third sector economies. The module will seek to develop student understanding of research methods relevant to human rights and human rights law and policy. It will develop skills that will enable students to evaluate content and to deliver responses that demonstrate the capacity to identify contemporary challenges for human rights, informed understanding and capacity for reflection on and application of research findings in particular areas of human rights.

  • LAAM20 Rights and accountability: technology and law

    This module examines issues pertaining to human rights and their protection in the use of technology. Students will consider how the online environment and human rights intersect by considering, inter alia: how human rights (such as the right to privacy and data protection rights) can be protected online; how new technologies can be used in investigating and prosecuting mass human rights violations; how technology can be used to automate and assist decision-making, where liability falls in those circumstances, and related issues of accountability and liability.
