Authoritarian regimes are also sometimes subcategorized by whether they are personalistic or populist. Personalistic authoritarian regimes are characterized by arbitrary rule and authority exercised mainly through patronage networks and coercion rather than through institutitions and formal rules..
Fluid accumulation is the most common cause of conductive hearing loss in the middle ear, especially in children. Major causes are ear infections or conditions that block the eustachian tube, such as allergies or tumors.
Conductive hearing loss occurs when sound is not conducted efficiently through the outer ear canal to the eardrum and the tiny bones (ossicles) of the middle ear. Conductive hearing loss usually involves a reduction in sound level or the ability to hear faint sounds. This type of hearing loss can often be corrected medically or surgically. Some possible causes of conductive hearing loss: 1  Fluid in the middle ear from colds. 2  Ear infection (otitis media). 3  Allergies (serous otitis media). 4  Poor eustachian tube function. 5  Perforated eardrum. 6  Benign tumors. 7  Impacted earwax (cerumen).
