Lessons at HRDAG: Making More Syrian Records Usable

If we could glean key missing information from those fields, we would be able to use more records.

14 Questions about Counting Casualties in Syria

In early 2012, HRDAG was commissioned by the UN Office of the High Commissioner for Human Rights (OHCHR) to do an enumeration project, essentially a count of all of the reported casualties in the Syrian conflict. HRDAG has published two analyses so far, the first in January 2013, and the second in June 2013. In this post, HRDAG scientists Anita Gohdes, Megan Price, and Patrick Ball answer questions about that project. So, how many people have been killed in the Syrian conflict? This is a complicated question. As of our last report, in June 2013, we know that there have been at least 93,000 reported, identifiable conflict-related casualties. The ...

Rionegro

Texto en Español Using Cemetery Information to Search for the Disappeared Lessons from a Pilot Study in Rionegro, Antioquia, Colombia Between May and July 2009, researchers from the Benetech Human Rights Data Analysis Group (HRDAG) conducted a pilot study to examine patterns of information about unidentified bodies at a cemetery in Rionegro, a town located Antioquia, Colombia. The study was carried out to support ongoing efforts by HRDAG's partner organization EQUITAS (Colombian Interdisciplinary Team for Forensic Work and Psychosocial Assistance) to identify bodies of unknown persons in the Rionegro cemetery. EQUITAS has found that cemeteries in ...

Rapid response to: Civilian deaths from weapons used in the Syrian conflict

On November 4, 2015, the BMJ published our "Rapid Response" to Civilian deaths from weapons used in the Syrian conflict (BMJ 2015;351:h4736). The response was co-authored by Megan Price, Anita Gohdes, Jay Aronson (Carnegie Mellon University, Center for Human Rights Science), and Christopher McNaboe (Carter Center, Syria Conflict Mapping Project). We have three concerns about this article. First, the article apportions responsibility for casualties to particular perpetrator organizations based on a single snapshot of territorial control that ignores the numerous (and well-documented) changes in this phenomenon over time. Second, combining Syrian ...

Convenience Samples: What they are, and what they should (and should not) be used for

As noted on our Core Concepts page, we spend a lot of time worrying about the ways data are used to make claims about human rights violations.  This is because inaccurate statistics can damage the credibility of human rights claims.  Analyses of records of human rights violations are used to guide policy decisions, determine resource allocation for interventions, and inform transitional justice mechanisms.  It is vital that such analyses are accurate. Unfortunately, all too often these decisions are based, inappropriately, on analyses of a single convenience sample. (more…)

CIIDH Data – Dictionary

Version date: 2000.01.29 Current version: ATV20.1 Patrick Ball & Herbert F. Spirer The unit of analysis for each record in this structure is VIOLATION. Each violation was of a particular type, happened at a particular time and place, and was committed by zero, one, or several organizational perpetrators. The violation was committed against zero or one named (individually identified) victim, and zero or more anonymous (unidentified) additional victims. The violation was reported one or more times in one, two, or three source types. Note that to count the number of times individuals suffered particular violations, users should sum either the ...

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 ...

Press Release, Chad, January 2010

NEW STUDY DOCUMENTS HISSÈNE HABRÉ’S OVERSIGHT OF POLICE PRISONS WHERE THOUSANDS DIED 10th Anniversary of Indictment of Chad Ex-Dictator January 29, 2010, N’Djamena, Chad and Palo Alto, CA, U.S. - On the 10th anniversary of the first indictment of Hissène Habré in Senegal, the Benetech Human Rights Data Analysis Group (HRDAG) released a new study showing that the former Chadian dictator was well informed of the hundreds of deaths that occurred in prisons operated by his political police. This information could be critical in the long delayed prosecution of Habré who has been accused of killing and systematically torturing thousands of politi...

Deportation Possible for El Salvador’s Gen. García – Supported by HRDAG Analysis

Gen. José Guillermo García, El Salvador’s defense minister from 1979 to 1983, may be deported from Florida to El Salvador because of his involvement in war crimes that occurred under his command. The recommendation comes from a Miami immigration judge, whose decision was supported with expert testimony from Stanford political science professor Terry Karl, who presented extensive statistical analysis of killings, disappearances, kidnappings, torture and other crimes under Gen. García’s watch. The statistical analysis was a joint effort between Professor Karl and Amelia Hoover Green and Patrick Ball of Human Rights Data Analysis Group (HRDAG). ...
