Quantitative Research at the AHPN Guatemala

In early 2006 I joined the Historical Archive of the National Police (Archivo Histórico de la Policía Nacional, or AHPN) without knowing the impact it would have on my future. I started with cleaning, organizing and classifying documents—and learning, with other colleagues, what a historical archive is and how it works. By April of that year, parallel to these learning processes, I was selected along with 20 other people to begin work on the challenging Quantitative Research project. I started as a "coder," transferring key content from documents into a database. (more…)

Sri Lanka

Ten years after the war ended in Sri Lanka, we still don’t know to the nearest ten thousand how many people perished. The estimates for the death toll for the last five months of the war alone vary between 7000 and 147,000. In 2011, the UN said it thought approximately 40,000 civilians had died; then in 2012 an internal UN report estimated it was at least 70,000. Population data from World Bank and UN sources indicated that more than 100,000 Tamils living in the conflict areas in the north have not returned home after the war. HRDAG has provided technical assistance to a broad range of non-governmental human rights organizations in Sri ...

CHANCE

Abstract: The challenges and opportunities researchers face when working with unstructured data are hardly new. This article defines unstructured data as data that is not organized according to pre-existing schemas or structures for the sake of statistical analysis. Unstructured data poses a unique challenge for researchers focused on police and policing. The article discusses a definition of unstructured data and two of the primary challenges faced when working with such data, namely information extraction and classification problems. Two case studies are used to illuminate the challenges. Read the article off-site.

HRDAG Testifies in Hissène Habré Trial

Last week HRDAG’s executive director, Patrick Ball, served as an expert witness for the prosecution in the trial of Hissène Habré, the ruler of Chad from 1982 to 1990. The trial is taking place in Dakar, Senegal, where the 73-year-old Habré has been living since 1990 when he fled Chad. He has already been sentenced to death in absentia in Chad. Habré is being charged with war crimes, crimes against humanity, and torture that took place during his eight-year reign. The trial is happening at the Extraordinary African Chambers, which was inaugurated by Senegal and the African Union to try Habré. This is the first time that one country has ...
