In daily lifestyle.

‘In daily lifestyle, if you believe of the impact of short power naps, about 15 to 20 minutes during the day usually, you can observe that amount of sleep can have a substantial positive effect on mood, interest, and well-being,’ study author Dr. Reut Gruber, director of the attention behavior and sleep laboratory at the Douglas Institute at McGill University, in Quebec, said to WebMD. The National Sleep Foundation recommends that children age range 5 through 12 obtain 10 to 11 hours of sleep each day. However, the experts behind the new study say that most school-aged children don’t actually get to bed until after 9 p.m., and 43 % of boys aged 10 to 11 sleep less than the advised nightly amount.A third reason could be that journals and publishers are increasingly multinational. Previously, the editor and editorial panel of a journal understood both the scientific field it covered and the people employed in it, but it’s extremely difficult to become sufficiently well linked when both editors and submissions result from all over the world. Having authors suggest the very best reviewers may therefore look like a good idea. In the aftermath of the latest scandals involving fake peer reviewers, many journals have decided to carefully turn off the reviewer-suggestion option on their manuscript-submission systems. But that move might not be enough, as the publisher Hindawi found out this past spring. Although Hindawi doesn’t allow authors suggest reviewers because of their manuscripts, it decided to examine the peer-review information for manuscripts submitted in 2013 and 2014 for possible fraud.
