Chad

Hissène Habré's rule over the former French colony of Chad, from 1982 to 1990, was marked by numerous and credible allegations of systematic torture and crimes against humanity. Habré claims that he was not aware of violations committed by the Documentation and Security Directorate (DDS), the state security force that pursued political opponents and operated notorious prisons during his regime. In January 2010, the Human Rights Data Analysis Group (HRDAG) released a new study showing that Habré was well informed of the hundreds of deaths that occurred in prisons operated by the DDS. The HRDAG report, State Coordinated Violence in Chad under ...

The case of Ana Lucrecia Orellana Stormont

When working with documents in an archive, every document offers the opportunity for statistical study and quantitative research. But a document can also offer the discovery of a story. That is the case with the disappearance of Ana Lucrecia Orellana Stormont, who was reported missing on June 6, 1983, at the age of 35. Ana Lucrecia, a professor of psychology at the University of San Carlos, was scheduled to attend a meeting with Edgar Raúl Rivas Rodríguez at the Plaza Hotel in Guatemala’s capital city. Edgar, who also went missing, was a teacher at the School of Political Science at the University. (Ana Lucrecia’s case is explained more fully ...

Kosovo 1999 – Using MSE to Examine Political Claims

Patrick Ball expanded his use of multiple systems estimation (MSE) to clarify the history of a deadly conflict in Kosovo. The violence began in 1989 when Serbian President Slobodan Milošević revoked Kosovo's autonomous status within the Republic of Serbia triggering fighting between Kosovar Albanians and the Yugoslav government. Allegations of widespread and systematic human rights violations were made against Serbian forces and NATO intervened to repel Serb forces from Kosovo. Ball and Scheuren gathered data from Albanian border crossings and other sources in the region. They used this information to examine the claim by the Yugoslav government ...

Training with HRDAG: Rules for Organizing Data and More

I had the pleasure of working with Patrick Ball at the HRDAG office in San Francisco for a week during summer 2016. I knew Patrick from two workshops he previously hosted at the University of Washington’s Centre for Human Rights (UWCHR). The workshops were indispensable to us at UWCHR as we worked to publish a number of datasets on human rights violations during the El Salvador Civil War.  The training was all the more helpful because the HRDAG team was so familiar with the data. As part of an impressive career which took him from Ethiopia and Kosovo to Haiti and El Salvador among others, Patrick himself had worked on gathering and analysing ...

Data Archaeology for Human Rights in Central America: HRDAG Collaborates with UWCHR

Patrick Ball is kicking himself for a decision he made almost 25 years ago. “I was clever, but I wasn’t smart,” he says ruefully, as he considers the labyrinth of tables and ASCII-encoded keystrings he used to design a database of human rights violations for the pioneering Salvadoran non-governmental Human Rights Commission (CDHES). Now I’m sitting in his office in San Francisco’s Mission District watching over his shoulder, and trying to keep up, as he bangs out code to decipher the priceless data contained in these old files. Created in 1991 and 1992, during the last days of El Salvador’s internal armed conflict, the files detail ...

Multiple Systems Estimation: The Matching Process

<<Previous post: Collection, Cleaning, and Canonicalization of Data Q8. What do you mean by "overlap," and why are overlaps important? Q9. [In depth] Why is automated matching so important, and what process do you use to match records?  Q8. What do you mean by "overlap," and why are overlaps important? MSE estimates the total number of violations by comparing the size of the overlap(s) between lists of human rights violations to the sizes of the lists themselves. By "overlap," we mean the set of incidents, such as deaths, that appear on more than one list of human rights violations. Accurately and efficiently identifying overlaps between ...

FAQs on Predictive Policing and Bias

Last month Significance magazine published an article on the topic of predictive policing and police bias, which I co-authored with William Isaac. Since then, we've published a blogpost about it and fielded a few recurring questions. Here they are, along with our responses. Do your findings still apply given that PredPol uses crime reports rather than arrests as training data? Because this article was meant for an audience that is not necessarily well-versed in criminal justice data and we were under a strict word limit, we simplified language in describing the data. The data we used is a version of the Oakland Police Department’s crime report...

Press Release, Timor-Leste, November 2006

Palo Alto, CA, November 12, 2006 –The Benetech® Initiative congratulates the Commission for Reception, Truth and Reconciliation (CAVR) and the Timorese people for the official release of the CAVR's final report Chega! in Australia today. The 2,500 page report uncovers previously unknown findings about past human rights abuses in Timor-Leste between 1974 and 1999. In particular, the report uncovers widespread and systematic human rights violations in Timor-Leste during the period 1974-1999. Benetech's statistical analysis establishes that at least 102,800 (+/- 11,000) Timorese died as a result of the conflict. Approximately 18,600 (+/- 1000) ...

HRDAG and the Digital Commons

One of the three main goals of HRDAG is education and outreach, and to that end we use Creative Commons licenses for all of our blogposts and, whenever possible, for our publications. Using a Creative Commons license makes it clear that educators are free to use HRDAG's publications, in their entirety, and with the peace of mind that they are doing so with our blessing. Also, the use of the Creative Commons license allows us to participate in and encourage the creation of a digital commons, which we feel helps to advance another one of our goals, the creation of knowledge. We feel that it’s important to offer up our publications for use and reuse ...

Data ‘hashing’ improves estimate of the number of victims in databases

But while HRDAG’s estimate relied on the painstaking efforts of human workers to carefully weed out potential duplicate records, hashing with statistical estimation proved to be faster, easier and less expensive. The researchers said hashing also had the important advantage of a sharp confidence interval: The range of error is plus or minus 1,772, or less than 1 percent of the total number of victims.

“The big win from this method is that we can quickly calculate the probable number of unique elements in a dataset with many duplicates,” said Patrick Ball, HRDAG’s director of research. “We can do a lot with this estimate.”
