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.
Primary arachnoid cysts, the congenital version, are usually caused by an abnormal growth of the brain and spinal column while the baby is developing in utero. This can be genetic. However, the exact cause of these growths is not known. Non-congenital arachnoid cysts in both children and adults can have several causes.
