Carroll's defines rath: "A species of land turtle. Head erect, mouth like a shark, the front fore, legs curved so that the animal walked on its knees, smooth green body, lived on swallows and
oysters." "There were probably sundials on the top of the hill, and the borogoves were afraid that their nests would be undermined. The hill was probably full of the nests of raths, which ran
out, squeakign with fear, on hearing the toves scratching outside. This is an obscure, but yet deeply-affecting, relic of ancient Poetry." Literal translation (guessing): It was evening, and the
smooth active badgers were scratching and boring holes in the hill-side; all unhappy were the parrots; and the grave turtles squeaked out.

reactive attachment disorder of infancy and early childhood -- a severe lack of attachment that affects the child's entire emotional development. Beginning before age 5 and occurring
in most situations, the child's social relatedness is markedly disturbed and developmentally inappropriate. This is shown by either of: 1)
inhibitions: In most situations, the child doesn't
interact in a socially appropriate way. This is shown by responses that are excessively inhibited,
hypervigilant or ambivalent and contradictory. For example, the child responds to
caregivers with frozen watchfulness or mixed approach-avoidance and resistance to comforting. OR 2)
disinhibitions: The child's attachments are diffuse, as shown by indiscriminate
sociability with the inability to form appropriate selective attachments. For example, the child is overly familiar with strangers or lacks selectivity in choosing attachment figures. This behavior is
not explained solely by a
developmental delay and it does not fulfill criteria for Pervasive Developmental Disorder. Evidence of persistent pathogenic care is shown by one or more of:
1) The caregiver neglects the child's basic emotional needs for affection, comfort, and stimulation; 2) the caregiver neglects the child's basic physical needs; 3) stable attachments cannot
form because of repeated changes of caregiver (such as frequent changes of foster care); 4) it appears that the pathogenic care just described has caused the disturbed behavior (for
example, the behavior began after the pathogenic behavior.)

understanding of the actual demands and constraints that might come with raising a child with a disability.

Disorders involving red blood cells include

red bone marrow --
(also called myeloid tissue) Red blood cells, platelets and most white blood cells arise in red marrow;
some white blood cells develop in
yellow bone marrow. The color of yellow marrow is  due to the much higher number of fat cells. Both kinds of bone marrow contain numerous blood
vessels and capillaries. At birth, all bone marrow is red. With age, more and more converts to yellow. Adults have an average of 5.7 pounds of bone marrow, with about half of it being red.
Red bone marrow is found mainly in the
flat bones such as the hip bone, breast bone, skull, ribs, vertebrae, and shoulder blades; and in the cancellous material at the proximal ends
of the
long bones femur and humerus. Pink marrow is found in the hollow interior of the middle portion of long bones. In case of severe blood loss, the body can convert yellow marrow
back to red in order to increase blood cell production.  

red caps -- "nasty little goblinlike creatures that lurked wherever there had been bloodshed; in the dungeons of castles and the potholes of deserted battlefields, waiting to bludgeon those

than seeing it as unlearned lessons reconstellated in the present,
Freud linked this to the death drive's push toward a return to previous conditions.

repetitive behaviors -- one of the three major characteristics of autism (others are communication difficulties and social symptoms). Odd repetitive movements may set a child with autism
apart from other children. These behaviors might be extreme and highly visible or more subtle. Some behaviors are such things as hand flapping, toe walking, suddenly freezing in positions,
lining up cars or trains (or other toys), or persistent, intense preoccupation, such as in vacuum cleaners, train schedules, etc. Often there is a great interest in numbers, symbols, or science

repressed anger -- the unconscious suppression of feelings of anger; so that they are expressed in other ways.

repression -- "Motivated forgetting;" the unconscious blocking of whatever is causing one stress. Freud: the ego's ridding itself of unacceptable desires and ideas by dumping them into
unconsciousness. Three conditions lead to a return of the repressed into
consciousness: when the counter-cathexis holding it down weaken; when the drives below it get stronger, or
when recent events similar in theme to what's repressed reawaken it; in all three cases the repressed shows up in the very method used for repression. "Primal repressions" are handed down
from the painful experiences of previous generations and keep certain contents of the
id from ever becoming conscious. "Repression proper" (also called "after expulsion") has to do with the
repression of associations and ideas related to whatever idea is chiefly being repressed. An aim of
psychoanalysis is to turn repression into condemnation.

called resolved singles.

resilience -- the ability to recover and not experience long-term harm from episodes of stress or a single negative experience; resilience is an abstract concept, resistant to measurement.

resistance -- Freud: the patient's efforts to remain unconscious of what is repressed. Common forms of resistance include arguing with the therapist, refusing to free associate, forgetting
to show up for a session, reducing spirit to a compensation for helplessness, and deploying
defense mechanisms in order to remain unaware of unconscious material. The negative
therapeutic reaction is the most difficult form of resistance and is motivated by a need to expiate an unconscious sense of guilt via
self-defeating behavior.

resistant attachment -- the quality of insecure attachment characterizing infants who remain close to the parent before departure, are usually distressed when she leaves, and mix
clinginess with angry, resistant behavior when she returns (in the Strange Situation
