PHILADELPHIA, Pa. – Within a series of unfinished walls, Tom Stefanko oversees hundreds of construction workers every day, all of them wearing what looks like an old-school pager. Yet, the technology involved is new.“I think it gives workers a little bit of comfort,” Stefanko said.The devices are proximity tracers, designed to make sure workers on construction sites remain socially-distant during these pandemic times.“If I was in contact another person, it would start beeping red,” Stefanko said. “And if I stayed there longer, it progressively beeps louder.”While they alert workers that they’re too close to one another, the proximity tracers also record that data, in case a worker later ends up testing positive for COVID-19.“It provides the ability to have a real-time alerting system and then also be able to go back historically and see who's been in contact with whom to do the contact tracing,” said Robert Costantini, CEO of Triax Technologies.The company began to develop the proximity tracers when the coronavirus outbreak began.“The stakes are really high, if you get it wrong,” Costantini said. “I mean, workers could be infected. You can shut your site down. The cost can be enormous.”The contact tracers, though, cost about a dollar a day, per worker. More than 15,000 of them are now in use on more than 70 construction sites around the country, including the 1 million square foot building that Tom Stefanko and his team are working on in Philadelphia.“We have a thousand tags here on site,” Stefanko said. “Most workers just keep it on their hardhat. And take it with them as they come and go – so, making it as part of their PPE.”It’s personal protective equipment that is now a requirement to try and keep COVID-19 out of their workforce. 1772

Pennsylvania has emerged as a hotspot for online misinformation on Election Day, with Facebook and Twitter trying to quickly take down false posts about voting in the state so they don’t confuse voters or stoke doubts about the integrity of the election. Misleading claims have spread for hours on social media about polling machine outages in Scranton and a poll worker destroying ballots cast for President Donald Trump. Misinformation experts say misleading videos, posts and photos from the battleground state are lighting up social media. 551

OXON HILL, Md. (AP) — The finals of the Scripps National Spelling Bee have begun, with 50 kids on stage competing for more than ,000 in cash and prizes and a new, custom-designed trophy.This year's bee had the biggest field ever, with 562 spellers, more than half of whom got in through Scripps' wild-card program. Last year was the first time that wild cards were allowed into the bee, and the eventual champion was a wild card.Thursday's finalists include nine spellers who finished in at least a tie for 10th last year. The field will be narrowed to about a dozen spellers in the morning and early afternoon before the prime-time finals on ESPN.The last 14 champions and 19 of the past 23 have been Indian-American. 729

Parents everywhere are looking for hot holiday toys — especially online. Unfortunately, so are computerized "Grinch Bots", which buy up huge amounts of the popular toys so they can be resold by scalpers at 3rd party websites with greatly marked-up prices."Grinch Bots" are able to search websites and grab the toys faster than consumers.It is such a concern that U.S. Senator Charles Schumer (D-NY) is pushing Congress to pass the "Stopping Grinch Bots Act of 2018."The proposed legislation would give the FTC authority to track and prosecute scalpers who use "Grinch Bots."Schumer's office found that, last year, "Grinch Bots" contributed to "sold out" status online for several popular toys which then showed up on sites like Ebay with inflated prices: 787

Parents worried about a lack of social-emotional growth in their young children during social distancing and child care closures, consider playing with the family dog or taking the whole family on the dog's walk.A study published this week in Pediatric Research points to improvements in toddlers’ behavior interacting with others when they have some amount of time spent with the family dog.Information from more than 1,600 parents were included in the study, which asked how old their children were, if they had a dog, how often the child went on the family dog walks or actively played with the dog, as well as other questions. In addition, parents filled out a Strengths and Difficulties Questionnaire about their child’s development and behavior.Overall, researchers found that preschool aged children from dog-owning homes had reduced likelihood of conduct problems and increased likelihood of prosocial behavior compared to children without a dog. Positive results were seen with family dog walking at least once a week and active play between the family and dog at least three times or more a week.The study’s authors report part of their motivation for the study was the decreasing physical activity levels of young children. They reference studies on increased activity among adult dog owners, and wanted to look at whether there were increased levels in children with dogs in the home.Participants live in Australia, and gave their survey results between 2015 to 2018 as part of a larger early childhood education and care research project.The Strengths and Difficulties Questionnaire is a commonly used, 25-item document that measures the social and emotional well-being of children.If a family dog is not possible at this time, maybe consider offering to walk a neighbor’s pet; physical activity, interacting with an animal and the benefit of doing something nice for a neighbor. 1900
