Public health agencies need ethical guidelines for deciding what to do when anonymous student health surveys discover a very high local rate of suicide-risk, according to CU researchers.
In a report published today in the highly influential American Journal of Bioethics, the researchers describe a student health survey team that discovered a Colorado school with extremely high rates of suicide risk, and a lack of ethical guidance on whether or how to intervene.
In March 2020, Covid-19 was declared a global pandemic, and governments around the world imposed restrictions to reduce the spread of the Coronavirus. Some countries chose stricter measures than others. But what effect does social distancing and similar measures have on our mental health? How do we adapt?
Researchers at UiT have compared corona restrictions in six countries, and looked at psychological reactions among the population, their confidence in the restrictions and belief that the government is in control over Covid-19 in their countries.
It is better to invest in measures that make it easier for women to visit a doctor during pregnancy than measures to repair birth injuries. This is the conclusion from two mathematicians at LiU, using Uganda as an example.
About a year ago, a conversation during a faculty meeting piqued Marcus Crede's interest. A senior faculty member in Iowa State University's Department of Psychology said that he believed frequent quizzes help students better grasp classroom material. Crede, an associate professor of psychology, was skeptical that something as simple as a quiz could positively impact students' academic performance. He decided to dig deeper and conduct a meta-analytic study of existing research to see if there was any merit to the claim. What he discovered truly surprised him.
In the 2019 Boeing 737 Max crash, the recovered black box from the aftermath hinted that a failed pressure sensor may have caused the ill-fated aircraft to nose dive. This incident and others have fueled a larger debate on sensor selection, number and placement to prevent the reoccurrence of such tragedies.
Texas A&M University researchers have now developed a comprehensive mathematical framework that can help engineers make informed decisions about which sensors to use and where they must be positioned in aircraft and other machines.
As more people work temporary gigs with little protection, or fear layoffs in an unstable economy, job insecurity is on the rise. These stresses understandably contribute to poor mental health and feelings of anxiety. But given gender disparities in the workforce - women are more likely to work temporary jobs and receive lower pay - researchers were curious whether job insecurity affected men and women differently.
SAN ANTONIO -- Sept. 16, 2020 -- A Southwest Research Institute scientist has identified stellar phosphorus as a probable marker in narrowing the search for life in the cosmos. She has developed techniques to identify stars likely to host exoplanets, based on the composition of stars known to have planets, and proposes that upcoming studies target stellar phosphorus to find systems with the greatest probability for hosting life as we know it.
EAST LANSING, Mich. - When people say that they want to change things about their personalities, they might not know about the inadvertent consequences these changes could bring. In fact, changes in personality may also lead to changes in political ideologies, say researchers from Michigan State University and the University of Granada, who led the study.
An international collaboration between researchers at Queen Mary University of London and the Chinese Academy of Science in Nanjing has led to the discovery of world's oldest animal sperm inside a tiny crustacean trapped in amber around 100 million years ago in Myanmar.
The research team, led by Dr He Wang of the Chinese Academy of Science in Nanjing, found the sperm in a new species of crustacean they named Myanmarcypris hui. They predict that the animals had sex just before their entrapment in the piece of amber (tree resin), which formed in the Cretaceous period.
People who have experienced post-traumatic stress disorder (PTSD) are up to twice as likely to develop dementia later in life, according to a new study by UCL researchers.
The research, published in the British Journal of Psychiatry, is the first meta-analysis of global evidence on PTSD and dementia risk.
For the study, the researchers analysed findings from 13 studies conducted on four continents, including data from a total of 1,693,678 people, investigating whether a PTSD diagnosis was associated with increased risk of dementia up to 17 years later.
Just how stressed are teachers? A recent Gallup poll found teachers are tied with nurses for the most stressful occupation in America today. Unfortunately, that stress can have a trickle-down effect on their students, leading to disruptive behavior that results in student suspensions.
One of those overburdened teachers is Jennifer Lloyd, a high school English teacher in Maryland and a graduate student at the University of Missouri. She has noticed how perceptive her students are to her mood and their ability to feed off of her energy, for better or worse.
Canada is the first country to facilitate provision of medical abortion in primary care settings through evidence-based deregulation of mifepristone, which is considered the 'gold standard' for medical abortion. A Canadian study investigated the factors that influence successful initiation and ongoing provision of medical abortion services among Canadian health professionals and how these factors relate to abortion policies, systems and service access throughout the country.
New research from UBC finds that after a night of shorter sleep, people react more emotionally to stressful events the next day--and they don't find as much joy in the good things. The study, led by health psychologist Nancy Sin, looks at how sleep affects our reaction to both stressful and positive events in daily life.
Due to their small size, nanoparticles find varied applications in fields ranging from medicine to electronics. Their small size allows them a high reactivity and semiconducting property not found in the bulk states. Sub-nanoparticles (SNPs) have an extremely small diameter of around 1 nm, making them even smaller than nanoparticles. Almost all atoms of SNPs are available and exposed for reactions, and therefore, SNPs are expected to have extraordinary functions beyond the properties of nanoparticles, particularly as catalysts for industrial reactions.
HANOVER, N.H. - September 14, 2020 - Information on social activity, screen time and location from smartphones can predict connectivity between regions of the brain that are responsible for emotion, according to a study from Dartmouth College.
In the research, data from phone usage was analyzed alongside results from fMRI scans to confirm that passively collected information can mirror activity in the brain linked to traits such as anxiety. Predictions based solely on the phone data matched the brain scans with 80 percent accuracy.
