Regulating Highly Automated Robot Ecologies: Insights from Three User Studies
Highly automated robot ecologies (HARE), or societies of independent
autonomous robots or agents, are rapidly becoming an important part of much of
the world's critical infrastructure. As with human societies, regulation,
wherein a governing body designs rules and processes for the society, plays an
important role in ensuring that HARE meet societal objectives. However, to
date, a careful study of interactions between a regulator and HARE is lacking.
In this paper, we report on three user studies which give insights into how to
design systems that allow people, acting as the regulatory authority, to
effectively interact with HARE. As in the study of political systems in which
governments regulate human societies, our studies analyze how interactions
between HARE and regulators are impacted by regulatory power and individual
(robot or agent) autonomy. Our results show that regulator power, decision
support, and adaptive autonomy can each diminish the social welfare of HARE,
and hint at how these seemingly desirable mechanisms can be designed so that
they become part of successful HARE.Comment: 10 pages, 7 figures, to appear in the 5th International Conference on

DNA Barcoding analysis of seafood accuracy in Washington, D.C. restaurants
Indexación: Scopus.In Washington D.C., recent legislation authorizes citizens to test if products are properly represented and, if they are not, to bring a lawsuit for the benefit of the general public. Recent studies revealing the widespread phenomenon of seafood substitution across the United States make it a fertile area for consumer protection testing. DNA barcoding provides an accurate and cost-effective way to perform these tests, especially when tissue alone is available making species identification based on morphology impossible. In this study, we sequenced the 5' barcoding region of the Cytochrome Oxidase I gene for 12 samples of vertebrate and invertebrate food items across six restaurants in Washington, D.C. and used multiple analytical methods to make identifications. These samples included several ambiguous menu listings, sequences with little genetic variation among closely related species and one sequence with no available reference sequence. Despite these challenges, we were able to make identifications for all samples and found that 33% were potentially mislabeled. While we found a high degree of mislabeling, the errors involved closely related species and we did not identify egregious substitutions as have been found in other cities. This study highlights the efficacy of DNA barcoding and robust analyses in identifying seafood items for consumer protection.https://peerj.com/articles/3234
Fully-Coupled Two-Stream Spatiotemporal Networks for Extremely Low Resolution Action Recognition
A major emerging challenge is how to protect people's privacy as cameras and
computer vision are increasingly integrated into our daily lives, including in
smart devices inside homes. A potential solution is to capture and record just
the minimum amount of information needed to perform a task of interest. In this
paper, we propose a fully-coupled two-stream spatiotemporal architecture for
reliable human action recognition on extremely low resolution (e.g., 12x16
pixel) videos. We provide an efficient method to extract spatial and temporal
features and to aggregate them into a robust feature representation for an
entire action video sequence. We also consider how to incorporate high
resolution videos during training in order to build better low resolution
action recognition models. We evaluate on two publicly-available datasets,
showing significant improvements over the state-of-the-art.Comment: 9 pagers, 5 figures, published in WACV 201

Magmatic Intrusions into the Sulfur-Rich Carmel Formation on the Colorado Plateau, USA: Implications for the Mars 2020 Mission
We report on basaltic dikes in the Colorado Plateau, which crosscut sulfate bearing sediments and compare this to Martian basalts and basaltic sediments in contact with sulfate mineralizations
Confusion in the Courts: What to Do with HIV-Positive and AIDS-Infected Public Employees
This paper is divided into five sections. Part one deals with background information on AIDS. Part two discusses current federal legislation. Part three examines how AIDS falls under federal legislation and case law, including the resulting impact of hiring AIDS-infected individuals. Part four evaluates possible violations of the Fourth Amendment resulting from the federal legislation and from an employer\u27s mandatory testing of employees for the HIV virus. The last section discusses the government\u27s liability when a public employee transmits AIDS to another individual during the course of employment
