OAEs are considered to be related to the amplification function of the cochlea. In the absence of external stimulation, the activity of the cochlear amplifier increases, leading to the production of sound. Several lines of evidence suggest that, in mammals, outer hair cells are the elements that enhance cochlear sensitivity and frequency selectivity and hence act as the energy sources for amplification. One theory is that they act to increase the discriminability of signal variations in continuous noise by lowering the masking effect of its cochlear amplification.
In 2009, Stephen Beeby of The University of Southampton led research into utilizing otoacoustic emissions for biometric identification. Devices equipped with a microphone could detect these subsonic emissions and potentially identify an individual, thereby providing access to the device, without the need of a traditional password. It is speculated, however, that colds, medication, trimming one's ear hair, or recording and playing back a signal to the microphone could subvert the identification process.
There are myriad sections without references. At other times the authors reference secondary sources (in discussing toilet training they note that "Pediatrician Lindy Woodard believes that a child can and should be trained by thirty months; in her professional experience, children who are trained at an older age have more problems learning to use the toilet." p. 168). Often the subject of a section would lack focus and context, such as p. 209 where the authors talk about "soul disorders" in reference to mental health. One assumes they are referencing the work of someone else, but it isn't cited or put into context. This leaves the reader to wonder why the authors would consider if "wisdom teeth extraction impacts our souls."
We recognize that there are good reasons to make changes in early childhood education and care (ECEC) in Ontario. But we believe that these must be based on the best available evidence about what is of most benefit to children and families; we argue that these proposed changes are not. Additionally, we suggest that changes in ECEC in Ontario will continue to have negative effects if they continue to be “piecemeal”.
"Miss Laura's" has been a wonderful second home for my daughter Helena. Helena was undergoing a rough transition this year, it being the first year she was to be cared for without big sis right by her side. Laura has made her home feel like a second home for Helena, and she makes nutrition important for the kids which I really like. She also follows whatever requests nutritionally that I have, and she is super careful. Helena's big sis has a severe peanut allergy, so Laura makes sure Helena never eats peanuts because she doesn't want to risk a problem when the two girls play in the afternoon. And I Didn't even have to ask her to do that!! That's great! Helena is really transitioning well and I think that is because of how Laura is helping it to feel like another home. My older daughter even constantly wants to stay with"Miss Laura." - Laura
Spontaneous otoacoustic emissions (SOAE)s are sounds that are emitted from the ear without external stimulation and are measurable with sensitive microphones in the external ear canal. At least one SOAE can be detected in approx. 35-50% of the population. The sounds are frequency-stable between 500 Hz and 4500 Hz to have unstable volumes between -30 dB SPL and +10 dB SPL. The majority of the people are unaware of their SOAEs; portions of 1-9% however perceive a SOAE as an annoying tinnitus.
In high school I was involved with sports (softball, basketball, track) was FFA vice president, and a member of the National Honor Society. After high school I received an athletic scholarship to play softball. While in college I started a physical education program at a local Lutheran Church School. The people and the children became family to me and I was offered a part time teaching assistant job working with the kindergarten class. During the summers of college I spent my time coaching softball to young girls. Over my four years of coaching we won four state titles, four regional titles, three Nationals appearances as well as an invitation to the Babe Ruth Little League World Series.
