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.
When an arachnoid cyst forms, the two leaflets of the membrane split apart. Cerebrospinal fluid then fills the cavity. Arachnoid cysts can be classified according to their location and by the type of tissue making up the cyst wall (arachnoid connective tissue or glioependymal tissue).
