Video Gaming Got Its First Major Union. Now What?

WIRED

History is about to take place in Madison, Wisconsin. A group of game developers have gathered in person to await the results of a National Labor Relations Board election that will determine whether the quality assurance workers at Call of Duty developer Raven Software have the majority vote needed to unionize roughly two dozen employees under the behemoth known as Activision Blizzard. "It's a beautiful day to unionize," says Jessica Gonzalez, a former Activision Blizzard employee who now works as a campaign organizer at CODE-CWA, in a Twitter Spaces stream on May 23. "It's taken months to get here," Gonzalez notes. Now it's just minutes before they'll learn whether employee efforts have been successful. "BOOM!" someone yells in the background, while Gonzalez announces the official verdict: 19 for and 3 against.


ACM's 2022 General Election

The ACM constitution provides that our Association hold a general election in the even-numbered years for the positions of President, Vice President, Secretary/Treasurer, and Members-at-Large. Biographical information and statements of the candidates appear on the following pages (candidates' names appear in random order). In addition to the election of ACM's officers--President, Vice President, Secretary/Treasurer--two Members-at-Large will be elected to serve on ACM Council. The 2022 candidates for ACM President, Yannis Ioannidis and Joseph A. Konstan, are working together to solicit and answer questions from the computing community! Please refer to the instructions posted at https://vote.escvote.com/acm. Please note the election email will be addressed from acmhelp@mg.electionservicescorp.com. Please return your ballot in the enclosed envelope, which must be signed by you on the outside in the space provided. The signed ballot envelope may be inserted into a separate envelope for mailing if you prefer this method. All ballots must be received by no later than 16:00 UTC on 23 May 2022. Validation by the Elections Committee will take place at 14:00 UTC on 25 May 2022. Yannis Ioannidis is Professor of Informatics & Telecom at the U. of Athens, Greece (since 1997).

You're muted... or are you? Videoconferencing apps may listen even when mic is off

#artificialintelligence

Kassem Fawaz's brother was on a videoconference with the microphone muted when he noticed that the microphone light was still on--indicating, inexplicably, that his microphone was being accessed. Alarmed, he asked Fawaz, an expert in online privacy and an assistant professor of electrical and computer engineering at the University of Wisconsin–Madison, to look into the issue. Fawaz and graduate student Yucheng Yang investigated whether this "mic-off-light-on" phenomenon was more widespread. They tried out many different videoconferencing applications on major operating systems, including iOS, Android, Windows and Mac, checking to see if the apps still accessed the microphone when it was muted. "It turns out, in the vast majority of cases, when you mute yourself, these apps do not give up access to the microphone," says Fawaz. "And that's a problem. When you're muted, people don't expect these apps to collect data."


New Book 'The Velocity of Information' Discovers Humans' Breaking Point During Chaos - California Newswire

#artificialintelligence

MADISON, Wis., Apr 11, 2022 (SEND2PRESS NEWSWIRE) -- "The Velocity of Information – Human Thinking During Chaotic Times" (ISBN: 978-1475865455), authored by David P. Perrodin, Ph.D., and published by Rowman & Littlefield, rigorously clarifies and deepens how we think about societal human behavior and mental health during days, weeks, months, or even years of chaos. This is an invigorating scholarly work for all audiences. As chaos erupts, alerts screech on our cell phones and torrents of conflicting-yet-urgent messages gush from media outlets. What is the magnitude of the crisis? And what should people do to protect themselves?


AI can now kill those annoying cookie pop-ups

#artificialintelligence

The EU may have brought freedoms, peace, and wealth to millions of people, but all those benefits have been nullified by one horrendous drawback: cookie pop-ups. The consent banners enforced by the bloc's privacy regulations are among the internet's most irritating features. The lawmakers behind them may have had good intentions, but they've merely trained us to blindly click through every notification. After years of suffering this digital torture, a new AI tool has finally offered hope of an escape. Named CookieEnforcer, the system was created by researchers from Google and the University of Wisconsin-Madison. The system was created to stop cookies from manipulating people into making website-friendly choices which put their privacy at risk.

Machine learning makes its mark on medical imaging and therapy – Physics World

#artificialintelligence

Artificial intelligence has potential to improve the operation of many essential tasks in various fields of medicine and biomedicine – from dealing with the massive amount of data generated by medical imaging, to understanding the evolution of cancer in the body, to helping design and optimize patient treatments. At last week's APS March Meeting, a dedicated focus session examined some of the latest medical applications of artificial intelligence and machine learning. Opening the session, Alison Deatsch from the University of Wisconsin, Madison, discussed the use of deep learning for diagnosing and monitoring brain disease. "Brain disorders and neurodegenerative disease are some of the most costly diseases, both in terms of human suffering and economic costs," she explained. The reason is that most of these conditions – which include Alzheimer's and Parkinson's disease, autism spectrum disorder and mild cognitive impairment (MCI), among others – lack reliable tools for diagnosis and progression monitoring and, as such, are often misdiagnosed.


NASA funds experimental radiation shield and Mars climbing robot

New Scientist

NASA has just announced the projects that will be getting money from its NASA Innovative Advanced Concepts (NIAC) programme, which aims to support ideas for game-changing mission designs and never-before-seen space exploration tech. Here we look at five of the concepts and how they will be used. Astronauts venturing to the moon or Mars in the future are likely to face a barrage of hazardous space radiation during their trips, including high-energy particles and nuclei known as cosmic rays. To protect crews, one NIAC study is exploring the idea of what the project's lead, Elena D'Onghia at the University of Wisconsin-Madison, calls a "deployable magnetic shield device". The CREW HaT system would consist of a ring of electrical coils positioned on arms roughly 5 metres from the spacecraft's main body.
