This method was replaced by a projection of the measured rank on the Bell Curve using an average IQ of 100 as the center value and a standard deviation of 15. Thus, the modern IQ is
a mathematical transformation of a raw score on an IQ test, based on the rank of that score in a normalization sample.

he/she may be removed to the IAES for not more than 45 days, without regard to whether or not the behavior is a manifestation of the disability. Previously, the law stated that if the behavior
is a manifestation of the disability, then the child may only be removed to an IAES for 10 days, or a maximum of 45 days for if the behavior involved drugs, weapons, or infliction of serious
bodily injury. If the behavior was NOT a manifestation of the disability, the child could be disciplined just like any other kid.

internal working model -- a set of expectations derived from early caregiving experiences concerning the availability of attachment figures, their likelihood of providing support during
times of stress, and the self's interaction with those figures. Becomes a model, or a guide, for all future close relationships. On the basis of cognitive psychology, Bowlby sees higher animals
as needing a map or model of the world in the brain, if they are successfully to predict, control, and manipulate their environment. In Bowlby's environmental model, telling us about the world,
and an organismal model, telling us about ourselves in relation to the world. We carry a map of self, and others, and the relationship between the two. Although primarily 'cognitive' in
conception, the idea of internal working models is applicable to affective life. The map is built up from experiences and is influenced by the need to defend against painful feelings. Thus an
anxiously attached child may have a model of others in which they are potentially dangerous, and therefore must be approached with caution, while their self-representation may be of
someone who is demanding and needy and unworthy to be offered security. The relationship with a person's primary caregivers is generalized in internal working models, which leads to a
distorted and incoherent picture of the world, and one that is not subject to updating and revision in the light of later experience. This, in Bowlby's eyes, is the basis for transference, and the
task of therapy is help the patient develop more realistic and less rigid internal working models.

congenital and chronic form is called chronic intestinal pseudo-obstruction (CIP). Usually the cause is unknown, but sometimes it is caused by abdominal or pelvic surgery, lupus
erythematosus, scleroderma, Parkinson's disease, infections, and certain medications. Symptoms are cramps, abdominal pain, nausea, vomiting, bloating, and constipation.
intestines -- a segment of the alimentary canal extending from the stomach to the anus. It consists of two segments, the large and the small. The small intestine is divided into the
duodenum, the jejunum, and the ileum. The large intestine consists of the cecum and the colon. The small intestine is grayish purple and about 1.5 inches in diameter; 20 -- 23 feet
long in an average adult man. The large intestine is a dark reddish color, and is roughly 5 feet long, on average. The intestines are covered with goblet cells which secrete mucus which
lubricates the passage of food along and protects the intestines from digestive enzymes. The small intestine secretes a hormone called secretin, which stimulates the pancreas to produce
digestive enzymes. Most food products are absorbed in the small intestine. The large intestine is responsible for absorption of water and excretion of solid waste.
