You could call him a forensic humanitarian.

HRDAG Analysis Supports Efforts to Hold Salvadoran Commanders Accountable for 1989 Jesuit Massacre

Almost a quarter century ago, on November 16, 1989, six Jesuit scholars, their housekeeper and her 15-year-old daughter were massacred inside the University of Central America (UCA) in San Salvador, El Salvador. Their chief target was the rector of the country’s leading university.

The United Nations–sponsored Truth Commission for El Salvador found that members of the Salvadoran military's high command “gave...the order to kill Father Ignacio Ellacuría and to leave no witnesses.” ...

IRR: Agreement Among Coders is Key

For years I have been engaged in a quantitative study at Guatemala’s Historic Archive of the National Police, or AHPN. (See the blogposts below.) In this study coders collect data on sheets of paper according to criteria established and explained in manuals. But when collecting data, there’s always room for human error—this is why the validity of the study hinges on verifying that coders use the correct criteria. It is important to mention that the mainstay of coding is the use of a controlled vocabulary. A controlled vocabulary gives analysts a framework, or frame of reference, when converting qualitative information into categories ...
