To empirically assess changes in the organisation of work as a result of computer tech-. nology adoption we deï¬ne a number of ï¬rm characteristics that capture the division of. labour and the skill level of the workforce.
An arachnoid cyst is a fluid-filled cyst that that occurs in the arachnoid membrane around the brain. While completely benign, and not a tumor per se, they can cause symptoms by compression of adjacent nervous system structures.he cyst wall is basically just arachnoid membrane and the cyst is filled with fluid which is essentially the same as cerebrospinal fluid. Some cysts do not appear to change in size while others can grow over time, compression adjacent neurological structures.
In many cases, arachnoid cysts do not cause symptoms (asymptomatic). In cases in which symptoms occur, headaches, seizures and abnormal accumulation of excessive cerebrospinal fluid in the brain (hydrocephalus) are common. The exact cause of arachnoid cysts is unknown.
