- Motivate Your High Performers to Share Their Knowledge - In a recent working paper, Harvard's Christopher Stanton discusses two common barriers to information sharing in a company. Underperforming employees can hesitate to ask for help, and high performers can be reluctant to offer it. Stanton and colleagues tracked two interventions in a call center environment. In the first, employees were paired, filled out worksheets describing strengths and weaknesses, and then compared notes on how to improve. In the second, employees were paired and offered a combined bonus on the team performance. The first protocol aimed to encourage underperformers to seek help, the second coaxed top-performers into offering it. Both approaches improved results during the study period, but workers who followed the second approach reverted to baseline performance five months later, whereas people who followed the first approach sustained their performance. Stanton speculates that the first approach helped people formulate better methods of productivity, whereas the second approach just caused people to work harder during the study period. The researchers suggest that businesses can harness this knowledge by setting up curated meetings where people have a reason to talk to each other and honestly assess strengths and weaknesses.
- Researchers: Are we on the cusp of an ‘AI winter’? - In the decades since the term, artificial intelligence (AI) was coined, the hype surrounding it has gone through peaks and troughs. The peaks in hype are often termed as "AI summer, and the troughs have been known as "AI winter". According to this article, the hype peaked in the 2010s, and there are signs that another AI winter may be on the way. As an example, the article suggests that many 2010 era thinkers were anticipating a sort of artificial general intelligence (AGI) that could function outside of a narrow domain, but in 2019, less people were predicting this in the foreseeable future, and the AIs that exist are still tightly focused on specific problems. NYU's Gary Marcus, is quoted to say that there is wide and growing awareness that new techniques are needed, and Edinburgh's Verena Rieser says that there is a feeling that the field has reached a plateau. Even among researchers who see a slow-down, however, not all agree that it is pushing towards a full AI winter, and some, such as IBM's Deep Mind group still have an optimistic perspective, saying that we have only scratched the surface of what may be achievable. -h/t Communications of the ACM: Artificial Intelligence
- Google plans to drop Chrome support for tracking cookies by 2022 - After a previous policy was criticized as "privacy gaslighting" (see Curating the Internet: Science and technology micro-summaries for August 26, 2019), Google now says that they'll discontinue support for tracking cookies in the Chrome browser by 2020. In August, Google said they would be deploying a so-called privacy sandbox in the chrome browser that can infer user preferences privately through the use of machine learning. Google's previous stance was that third-party tracking cookies were preferable to the alternative, a mechanism known as browser fingerprinting. Now, however, the company says that the privacy sandbox will make third-party tracking cookies obsolete, and they will discontinue support by 2022. As-of yet, there has not been enough public progress on the privacy sandbox for security researchers to assess the functionality. Google says that feedback from industry insiders has been positive. To me, without knowing the detailed implementations, the privacy sandbox sounds superficially similar to the way that the Brave browser delivers ads while simultaneously protecting user privacy.
- Forget What You Think You Know About Blue Light and Sleep - There is a widespread belief that light near the blue range of the visible light spectrum can cause difficulty with sleep, but a December paper in Current Biology challenges the claim. The paper's authors exposed mice to warm-toned yellow light and cool-toned blue light, and they found that the yellow light disturbed the sleep more than the blue. To explain this, they hypothesize that warm-toned light resembles sunlight and stimulates wakefulness whereas cool-toned light resembles twilight.
- STEEM Energy - Coal - In this post, @scholaris tells us about the history and use of coal as an energy source, beginning as far back as Europe of 73,000 years ago and with wide-spread use as early as 3,500 years ago in China. The post notes that coal is easy to light and creates productive energy, light, and warmth when burned. The article goes on with illustrations and descriptions covering the process of burning coal to spin a steam-turbine which drives a generator and creates electricity. It then discusses the importance of safe disposal of the waste from a coal-powered generator, listing the cases of Kingston, TN and Eden, NC as examples of what happens when the disposal is not handled safely. In Kingston, the post says says that as many as 200 clean-up workers have been sickened or killed after the company forbade them to wear protective gear during a spill cleanup. In contrast, Eden also experienced a spill, but the cleanup was so quick and safe that the response received praise from environmentalists. Surprisingly, the article quotes Scientific American in saying that, "Coal ash is more radioactive than nuclear waste." This is because trace elements of radioactive materials are present in coal, but they become more concentrated as the coal, itself, burns away. The article also asserts that clean coal technology has not yet been deployed in the US, but has in other places like Korea and China. Finally, it notes that coal is abundant, cheap, and after centuries of use, there is still enough supply to last for centuries more. Continued use is nearly certain, but clean technologies can make coal safer for people and the environment. (A beneficiary setting of 10% has been applied to this post for @scholaris.)
