Video Gaming Got Its First Major Union. Now What?


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.

Book characters are four times more likely to be male than female, a gender bias study has revealed

Daily Mail - Science & tech

Characters in books are about four times more likely to be male than female, a new study of gender bias in literature has revealed. Researchers at the USC Viterbi School of Engineering used artificial intelligence to examine more than 3,000 English-language books ranging from science fiction and adventure, to mystery and romance - across short stories, poetry and novels. The team found male characters appeared four times as often as females across the books, although that reduced when the author of the work was female. There were also more negative terms used in connection with the female characters such as'weak' and'stupid' compared to'strong' and'power' used for men. 'Gender bias is real, and when we see females four times less in literature, it has a subliminal impact on people consuming the culture,' said author Mayank Kejriwal.

NLRB ruling gives green light to Raven Software union vote

Washington Post - Technology News

In late January, that group of workers filed a petition with the NLRB for a union election after parent company Activision Blizzard missed a deadline set by the group to voluntarily recognize the nascent union, named the Game Workers Alliance. Activision Blizzard contested the filing, arguing that any union at the Wisconsin-based Raven would have to encompass all of the studio's approximately 230 employees -- a far broader swath of workers than just the quality assurance team. The NLRB's decision rejected that argument, finding that the set of quality assurance testers was an appropriate bargaining unit.

Study Finds Artificial Intelligence May Improve Diabetes Diagnosis - AI Summary


Bethesda (Maryland) [US], April 16 (ANI): A new study has found that a fully-automated artificial intelligence (AI) deep learning model can identify early signs of type 2 diabetes on abdominal CT scans. For this retrospective study, Dr Summers and colleagues, in close collaboration with co-senior author Perry J. Pickhardt, M.D., professor of radiology at the University of Wisconsin School of Medicine & Public Health, used a dataset of patients who had undergone routine colorectal cancer screening with CT at the University of Wisconsin Hospital and Clinics. The deep learning model displayed excellent results, demonstrating virtually no difference compared to manual analysis. In addition to the various pancreatic features, the model also analyzed the visceral fat, density and volumes of the surrounding abdominal muscles and organs. The best predictor's type 2 diabetes in the final model included intrapancreatic fat percentage, pancreas fractal dimension, plaque severity between the L1-L4 vertebra level, average liver CT attenuation, and BMI.

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


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."
