Participatory Archives

This article explores how concerns about the democratization of representation and new technologies has shaped practices for collecting, organizing, preserving, interpreting, and circulating media. It outlines a participatory process of archival development informed by the emerging field of digital public humanities (DPH) and our research on the history of participatory media-making in the United States. We begin by tracing the development of Participatory Media, a digital and public project that collects and presents 1960s and 1970s film and related material. We then turn to how the project is shaped by DPH. We conclude by explaining how the history of participatory media can help DPH scholars understand both the strengths and limits of the contemporary turn toward participatory archival practices

Perspectives on Harmful Speech Online

This collection of essays includes perspectives on and approaches to harmful speech online from a wide range of voices within the Berkman Klein Center community. Recognizing that harmful speech online is an increasingly prevalent issue within society, we intend for the collection to highlight diverse views and strands of thought and to make them available to a wide range of audiences. We issued an open call to our community for short pieces that respond to issues related to harmful speech online. Through this collection, we sought to highlight ongoing research and thinking within our extended community that would be available to readers in a way that is more accessible than traditional academic research. The 16 short essays compiled in this collection are authored by a global group of friends, colleagues, and collaborators. We hope that this diverse mix of perspectives, viewpoints, and data points provokes thought and debate, and inspires further exploration. Evidence of the complexity of the issue is that no two writers sought to cover the same topic from a similar point of view; from legal perspectives to research results to paradigm-shifting provocations, a multitude of topics, opinions, and approaches are included. Many pieces draw from research, while others are more opinion-based, indicating that discourse around this topic can be inherently opinionated and passionate as well as scholarly and academic. Some pieces are written in a style evocative of advocacy, whereas others are written with scholarly communities in mind. The range of perspectives and opinions found here—and the lack of consensus on some topics—highlight the dynamic complexity of the issues and how competing values are frequently entangled. The pieces  are organized into three categories: Framing the Problem, International Perspectives, and Approaches, Interventions, and Solutions. The first and last sections include essays that build upon our understanding of their categories, and the section on International Perspectives addresses specific geopolitical contexts and ways in which the regulation of harmful speech may or may not be serving the citizens of a particular country or region.

Acute flaccid myelitis: cause, diagnosis, and management

Acute flaccid myelitis (AFM) is a disabling, polio-like illness mainly affecting children. Outbreaks of AFM have occurred across multiple global regions since 2012, and the disease appears to be caused by non-polio enterovirus infection, posing a major public health challenge. The clinical presentation of flaccid and often profound muscle weakness (which can invoke respiratory failure and other critical complications) can mimic several other acute neurological illnesses. There is no single sensitive and specific test for AFM, and the diagnosis relies on identification of several important clinical, neuroimaging, and cerebrospinal fluid characteristics. Following the acute phase of AFM, patients typically have substantial residual disability and unique long-term rehabilitation needs. In this Review we describe the epidemiology, clinical features, course, and outcomes of AFM to help to guide diagnosis, management, and rehabilitation. Future research directions include further studies evaluating host and pathogen factors, including investigations into genetic, viral, and immunological features of affected patients, host-virus interactions, and investigations of targeted therapeutic approaches to improve the long-term outcomes in this population
