The Next American Revolution: Sustainable Activism for the Twenty-First Century By Grace Lee Boggs with Scott Kurashige

During her 96 plus years on the planet, Boggs has been an active participant in the most profound social movements of the twentieth century. After earning her Ph.D. in Philosophy from Bryn Mawr College in 1940, she embarked on a career as a social activist that has spanned 70 years. Her lived experiences as a Chinese American woman, philosopher, feminist, environmentalist, civil rights leader, community organizer, and wife to Black labor activist Jimmy Boggs have given her a unique perspective on what it means to be an activist in the twenty-first century. She truly has made her road by walking (Horton & Friere, 1990). Grace Lee Boggs’ book, The Next American Revolution: Sustainable Activism for the Twenty-First Century (2010), is both a retrospective look on her life as an activist-philosopher and a hopeful road map for a way forward in the twenty-first century. It is required reading for all who aspire to create a more livable, democratic and sustainable future for the planet

Bringing UMAP Closer to the Speed of Light with GPU Acceleration

The Uniform Manifold Approximation and Projection (UMAP) algorithm has become widely popular for its ease of use, quality of results, and support for exploratory, unsupervised, supervised, and semi-supervised learning. While many algorithms can be ported to a GPU in a simple and direct fashion, such efforts have resulted in inefficient and inaccurate versions of UMAP. We show a number of techniques that can be used to make a faster and more faithful GPU version of UMAP, and obtain speedups of up to 100x in practice. Many of these design choices/lessons are general purpose and may inform the conversion of other graph and manifold learning algorithms to use GPUs. Our implementation has been made publicly available as part of the open source RAPIDS cuML library (https://github.com/rapidsai/cuml)

Building an Electronic Learning Community: From Design to Implementation

The University of Maryland at College Park in cooperation with Baltimore City Public Schools and several partners is working to build an electronic learning community that provides teachers with multimedia resources that are linked to outcome-oriented curriculum guidelines. The initial resource library contains over 1000 videos, texts, images, web sites, and instructional modules. Using the current system, teachers can explore and search the resource library, create and present instructional modules in their classrooms, and communicate with other teachers in the community. This paper discusses the iterative design process and the results of informal usability testing. Lessons learned are also presented for developers.

Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe
