We find that digitization amplified the staff's repurposing of the archive to serve victims of human rights violations. Digitization enhances short-and long-term safeguards for the archive's physical integrity, probative value and enduring accessibility, but has required critical human factors and institutional solidarity, most notably partnerships with international donors and allied organizations, and Guatemalan nongovernmental organizations. Finally, technology offers a lens to analyze the persistent challenges to promoting truth and justice in Guatemala. We show how simple, often ad hoc approaches to digitization developed under political urgency can have an irreversible impact when used to amplify a unified mission driven by a committed community of archival workers.

We provide empirical evidence from the Historical Archive of the Guatemalan National Police (AHPN) that the police used language, terminology and codes to record deaths in ways that produced silences about the level of violence during the height of repressive military rule. Using a dataset derived from a statistically valid sample of police records together with qualitative archival analysis, we find evidence of profound changes in the terminology used to record and report on deaths-changes that follow a pattern consistent with the policies of information control and concealment of the three different military regimes that ruled Guatemala between 1978 and 1985. We argue that researchers will need to consider the silences created through the selective use of terminology in documents when using archives to produce historical knowledge. Detecting and intercepting silence will be especially important as state records are increasingly sought in service of ongoing pursuits for truth and justice about past atrocities.

The Ford Foundation, the John D. and Catherine T. MacArthur Foundation, the Open Society Foundations, the Oak Foundation and Humanity United, seeking to make strategic investments to harness technology in the service of human rights, face choices about priorities and opportunities for strategic collaboration as well as risks and challenges in this rapidly changing field.This study shows how the HR-Tech space encompasses technology both as infrastructure on which rights in the digital and the physical worlds depend, and as instruments that can help make human rights defenders and their work more effective and secure. Many HR-Tech discussions focus too narrowly on the challenges related to the development a...

How common is sexual violence in the Democratic Republic of Congo? Is it “widespread and systematic” tactic of one or more armed groups? Did Colombia’s paramilitary demobilization program actually reduce violence against noncombatants? How many Iraqi civilians have died during the ongoing American-led conflict there? How does that number compare to the number of soldiers and insurgents killed? Each of these high-stakes questions asks the analyst to estimate the “dirtiness” of a military action. Directly or indirectly, each can be (and has been) answered using quantitative evidence. Different answers point to radically different legal and policy conclusions. Given the dire consequences of wrong answers, quantitative research in human rights demands accuracy—or, at the least, an honest accounting of uncertainty. Yet armed conflicts (like many other human rights crises) are nearimpossible contexts for the collection of comprehensive, or even represen...

We investigate their technology use, risk perceptions, and protective strategies relating to their vulnerability. Through semi-structured interviews with Latinx undocumented immigrants, we find that while participants act to address offline threats, this vigilance does not translate to their online activities. Their technology use is shaped by needs and benefits rather than risk perceptions. While our participants are concerned about identity theft and privacy generally, and some raise concerns about online harassment, their understanding of government surveillance risks is vague and met with resignation. We identify tensions among self-expression, group privacy, and self-censorship related to their immigration status, as well as strong trust in service providers. Our findings have implications for digital literacy education, privacy and security interfaces, and technology design in general. Even minor design decisions can substantially affect exposure risks and well-being for such vulnerable communities.

The Archive contains millions of documents, which were initially found mixed together and in poor physical condition. Given the Archive size and the lack of a traditional sample frame, we opted for a multi-stage random PPS sample using the Archive's topography for stages 1 and 2. For stages 3 and 4, frames were created on location. The sampling faced several challenges, including movement of the documents as they were being restored and organized, and uncertain resource availability. To manage these difficulties we drew iterative sample waves. After rounds of evaluation, we modified the sampling to reduce one stage, making the sampling more efficient. Over 2 years of sampling, we have selected 20,000 documents. Next, we may use adaptive sampling to search more deliberately and probabilistically for documents of interest.
