The Genealogy of Ideology: Predicting Agreement and Persuasive Memes in the U.S. Courts of Appeals

We employ machine learning techniques to identify common characteristics and features from cases in the US courts of appeals that contribute in determining dissent. Our models were able to predict vote alignment with an average F1 score of 73%, and our results show that the length of the opinion, the number of citations in the opinion, and voting valence, are all key factors in determining dissent. These results indicate that certain high level characteristics of a case can be used to predict dissent. We also explore the influence of dissent using seating patterns of judges, and our results show that raw counts of how often two judges sit together plays a role in dissent. In addition to the dissents, we analyze the notion of memetic phrases occurring in opinions - phrases that see a small spark of popularity but eventually die out in usage - and try to correlate them to dissent

SecBench.js: An Executable Security Benchmark Suite for Server-Side JavaScript

Npm is the largest software ecosystem in the world, offering millions of free, reusable packages. In recent years, various security threats to packages published on npm have been reported, including vulnerabilities that affect millions of users. To continuously improve techniques for detecting vulnerabilities and mitigating attacks that exploit them, a reusable benchmark of vulnerabilities would be highly desirable. Ideally, such a benchmark should be realistic, come with executable exploits, and include fixes of vulnerabilities. Unfortunately, there currently is no such benchmark, forcing researchers to repeatedly develop their own evaluation datasets and making it difficult to compare techniques with each other. This paper presents SecBench.js, the first comprehensive benchmark suite of vulnerabilities and executable exploits for npm. The benchmark comprises 600 vulnerabilities, which cover the five most common vulnerability classes for server-side JavaScript. Each vulnerability comes with a payload that exploits the vulnerability and an oracle that validates successful exploitation. SecBench.js enables various applications, of which we explore three in this paper: (i) crosschecking SecBench.js against existing security advisories reveals 168 vulnerable versions in 19 packages that are mislabeled in the advisories; (ii) applying simple code transformations to the exploits in our suite helps identify flawed fixes of vulnerabilities; (iii) dynamically analyzing calls to common sink APIs, e.g., exec(), yields a ground truth of code locations for evaluating vulnerability detectors. Beyond providing a reusable benchmark to the community, our work identified 20 zero-day vulnerabilities, most of which are already acknowledged by practitioners

Incidental Chiari 1 malformation - yet another intra-operative cause for bradycardia: a case report: Incidental Chiari 1 malformation and intra-operative bradycardia

Chiari 1 malformation is characterized by descent of cerebellar tonsils through the foramen magnum. Most patients are asymptomatic or may present with non specific symptoms. We present a case of a 13 year old incidentally detected to have Chiari 1 malformation and developed significant bradycardia in the intra-operative perio

An Official American Thoracic Society Research Statement: Implementation Science in Pulmonary, Critical Care, and Sleep Medicine

BackgroundMany advances in health care fail to reach patients. Implementation science is the study of novel approaches to mitigate this evidence-to-practice gap.MethodsThe American Thoracic Society (ATS) created a multidisciplinary ad hoc committee to develop a research statement on implementation science in pulmonary, critical care, and sleep medicine. The committee used an iterative consensus process to define implementation science and review the use of conceptual frameworks to guide implementation science for the pulmonary, critical care, and sleep community and to explore how professional medical societies such as the ATS can promote implementation science.ResultsThe committee defined implementation science as the study of the mechanisms by which effective health care interventions are either adopted or not adopted in clinical and community settings. The committee also distinguished implementation science from the act of implementation. Ideally, implementation science should include early and continuous stakeholder involvement and the use of conceptual frameworks (i.e., models to systematize the conduct of studies and standardize the communication of findings). Multiple conceptual frameworks are available, and we suggest the selection of one or more frameworks on the basis of the specific research question and setting. Professional medical societies such as the ATS can have an important role in promoting implementation science. Recommendations for professional societies to consider include: unifying implementation science activities through a single organizational structure, linking front-line clinicians with implementation scientists, seeking collaborations to prioritize and conduct implementation science studies, supporting implementation science projects through funding opportunities, working with research funding bodies to set the research agenda in the field, collaborating with external bodies responsible for health care delivery, disseminating results of implementation science through scientific journals and conferences, and teaching the next generation about implementation science through courses and other media.ConclusionsImplementation science plays an increasingly important role in health care. Through support of implementation science, the ATS and other professional medical societies can work with other stakeholders to lead this effort
