Workers may sense it intuitively but their mouse clicks prove it: Friday afternoon is the least productive time of the work week. It’s also when workers make the most typos. A Texas A&M University team studied this using the computer usage metrics of 789 in-office employees at a large energy company over two years. “Most studies of worker productivity use employee self-reports, supervisory evaluations or wearable technology, but these can be subjective and invasive,” said co-author Mark Benden, head of the university’s Department of Environmental and Occupational Health. “Instead, we used computer usage metrics — things like typing speed, typing errors and mouse activity — to get objective, noninvasive data on computer work patterns,” he said in a university news release. The researchers compared computer use across different days of the week and times of the day to see what kinds of patterns emerged. “We found that computer use increased during the week, then dropped significantly on Fridays,” said study leader Taehyun Roh, an assistant professor of epidemiology and biostatistics. “People typed more words and had more mouse movement, mouse clicks and scrolls every day from Monday through Thursday, then less of this activity on Friday.” Computer use fell off every afternoon — especially on Fridays — the data revealed. “Employees were less active in the afternoons and made more typos in the afternoons —…  read on >  read on >

Ever feel like your job is pointless? A big part of the population feels just that way — that the jobs they do matter little to society. And a Swiss study that delved into what’s been dubbed the “bullshit jobs theory” found that feeling was especially likely for folks in financial, sales and management jobs. About 19% of employees found their work rarely or never gave them “a feeling of making a positive impact on community and society” and “the feeling of doing useful work,” the study found. That finding is in line with the “bullshit jobs theory” espoused by the late American anthropologist David Graeber, who maintained that some jobs are socially useless. “Employees’ assessment of whether their work is perceived as socially useless is a very complex issue that needs to be approached from different angles,” study leader Simon Walo, a sociologist at the University of Zurich, said in a university news release. “It depends on various factors that do not necessarily have anything to do with the actual usefulness of work as claimed by Graeber. For example, people may also view their work as socially useless because unfavorable working conditions make it seem pointless,” Walo explained. In addition to Graeber’s theory, other researchers have suggested that people consider their jobs useless not because of the importance of their work but because it…  read on >  read on >

When studying which personality types were more likely to resist getting vaccines, researchers got a surprise. It was the extroverts who were more vaccine resistant. Compared to other personality styles, extroverts were 18% more likely to refuse the COVID-19 vaccine, the new study finds. “We expected that people who were especially high in extroversion would be more likely to get the vaccine,” said lead author Melissa Baker, an assistant professor at the University of Texas at El Paso. “We figured those people would want to get back out in the world and socialize, right? It’s actually the opposite,” she added in a university news release. The researchers hope their findings may help with future public health messaging and vaccination campaigns. “We wanted to look at vaccine hesitancy a different way,” Baker said. “Of course, politics can help explain some of it, but there are personal differences between people, too — and that led us to this personality aspect.” Joining with a researcher from the University of Toronto, the study team used surveys of more than 40,000 Canadian adults, taken between November 2020 and July 2021. Questions evaluated each participant’s personality, based on a model known as “big five.” This gauges someone’s openness, conscientiousness, extraversion, agreeableness and emotional stability. Other questions were focused on vaccination, including, “When a COVID-19 vaccine becomes available, will you be vaccinated?”…  read on >  read on >

The trauma and unhappy family dynamics of childhood may follow kids into old age, affecting both their mind and body, according to new research. “We looked at self-reported disability, as well as objectively measured physical and cognitive impairment, and learned that early-life stressful experiences can have ramifications all the way into older age,” said senior author Dr. Alison Huang, a University of California, San Francisco professor of medicine. “This can mean a higher likelihood of difficulty walking, or carrying out activities of daily living, or problems with memory when people are in their 60s, 70s, 80s or older,” she said in a university news release. Exposure to physical violence or abuse, severe illness, family financial stress or separation from parents are considered major childhood stressors. The study found that those who experienced violence in childhood were 40% more likely to have mobility impairment and 80% more likely to have difficulty with daily activities. Those who came from unhappy families were 40% more likely to have mild cognitive impairment. According to the U.S. Centers for Disease Control and Prevention, almost 60% of adults in the United States have experienced one or more types of adverse childhood experiences. These can undermine a child’s sense of safety or stability, and are tied to later heart disease, diabetes, autoimmune disease and depression. California was the first state to mandate…  read on >  read on >

J.D. Butler was planning a future with his girlfriend at his favorite New York City restaurant when that future came to a sudden, crushing halt. “They were planning on when she was moving in and arranging floor plans on the table, with where the furniture was going to go,” said his mother, Karen Butler, a lifelong New York resident. “And he had a grand mal seizure, and then his heart stopped.” A subsequent autopsy revealed that J.D.’s fatal seizure was brought on by mitragynine toxicity, caused by long-term ingestion of the widely used herbal supplement kratom, Butler said. “She said there was evidence in his organ tissue that it had been in his body consistently for a while,” Butler said. “It’s one of those drugs to which you develop a tolerance, so you have to keep taking more and more and more.” Kratom is coming under fire in the United States, targeted by a series of lawsuits following wrongful deaths associated with its use. A Florida jury awarded $11 million last week to the family of a woman who died after taking kratom, in a lawsuit against the company that sold her the supplement, according to NBC News. The woman, a 39-year-old mother of four, collapsed in her kitchen while making breakfast for her family in June 2021. A coroner said Krystal Talavera died from…  read on >  read on >

So, your high schooler has been complaining of headaches. Should you worry? Maybe, claims new research that finds bullying and suicidal thoughts are both linked to more frequent headaches in teens. “Headaches are a common problem for teenagers, but our study looked beyond the biological factors to also consider the psychological and social factors that are associated with headaches,” said study author Dr. Serena Orr, of the University of Calgary, in Canada. “Our findings suggest that bullying and attempting or considering suicide may be linked to frequent headaches in teenagers, independent of mood and anxiety disorders.” This isn’t proof that bullying causes headaches, but shows an association between the two. A study limitation is that headaches were self-reported. The research included more than 2.2 million teens who were an average age of 14. About 0.5% of all the participants self-reported being gender-diverse, including transgender or nonbinary. The participants answered questions about their headaches, including if they had them in the past six months and how often. The teens also answered questions regarding mental health, including whether they had diagnosed mood or anxiety disorders or both; about bullying in the past year and about suicidal thoughts and attempts. About 11% of participants reported having frequent, recurring headaches, defined as headaches occurring more than once a week. About 25% of the participants reported being victims of frequent…  read on >  read on >
