We propose to strengthen user-selected passwords against statistical-guessing attacks by allowing users of Internetscale systems to choose any password they want—so long as it’s not already too popular with other users. We create an oracle to identify undesirably popular passwords using an existing data structure known as a count-min sketch, which we populate with existing users’ passwords and ...

Their results show that no significant difference was found between group members’ comprehension of contributed comments and their stated minimum acceptable understanding. However, comprehension of relevant comments was higher than that for off-topic text, indicating that the sharing of important information wa...

We derive standards for acceptable measurement error when inferring treatment effects from sample means. The standards arise from the amount of measurement accuracy required for sample means to beat a näıve benchmark estimator that randomizes the direction and magnitude of treatment effects. We show that at sample and effect sizes common to many areas of psychology, particularly in human subjec...

We describe an inadequate antibody response to rabies vaccine in an immunocompromised patient. A literature search revealed 15 additional immunocompromised patients, of whom 7 did not exhibit the minimum acceptable level of antibodies after a complete postexposure prophylaxis regimen. An international rabies registry is needed to provide a basis for determining appropriate vaccination protocols.

Factors related to the height of the load and the frequency of handling have become a way to predict the acceptable standard weight lifted for workers whose main task is the manual lifting of materials and measuring the conditions is important to determine a maximum weight lifted. This study was conducted to twenty (20) workers between eighteen (18) and forty (40) years old with a minimum six m...
