motion

 [mo´shun]
motion sickness discomfort felt by some people on a moving boat, train, airplane, or automobile, or even on an elevator or a swing. The discomfort is caused by irregular and abnormal motion that disturbs the organs of balance located in the inner ear. There may be mild symptoms of nausea, dizziness, or headache, as well as pallor and cold perspiration. In more acute cases, there may be vomiting and sometimes prostration. Though most people quickly adapt to travel by airplane, ship, and automobile, few are wholly immune to motion sickness. Even astronauts become ill if the inner ear organs of balance are continuously stimulated by unusual motion. Fortunately, most cases of motion sickness vanish quickly once the journey is over, leaving no ill effects.
Causes. The inner ear possesses three semicircular canals, located at right angles in three different planes. People are accustomed to movement in the horizontal plane, which stimulates certain semicircular canals, but not to vertical movements such as the motion of an elevator or a ship pitching at sea. These vertical movements stimulate the semicircular canals in an unusual way, producing the sensation of nausea, or motion sickness.

Anxiety, grief, or other emotions can also cause motion sickness. A person unaccustomed to traveling by boat or airplane may be apprehensive or nervous and therefore may develop symptoms of nausea. Some individuals with previous experience of motion sickness become ill on a boat at dock or on an airplane prior to take-off.

Airsickness usually occurs during a bumpy flight caused by stormy weather or turbulent air. However, it may also be triggered by poorly ventilated cabins, hunger, digestive upset, overindulgence in food and drink, and unpleasant odors, particularly tobacco smoke.
Treatment. Certain antihistamines have proved highly effective in treating symptoms of seasickness. Like depressants, they may be used alone or in combination with mild sedatives. Those who suffer from motion sickness should ask their health care provider for advice before they embark on a trip. Symptoms may also be reduced if the seasick person rests lying down, with the head low, in a comfortable, well aired place.
Prevention. Being rested and in good health prior to a journey helps to prevent motion sickness. During a voyage by boat, it is advisable for the passenger to remain near the center of the ship, where there will be the least motion. Ample fresh air and exercise and avoidance of stuffy rooms and disagreeable smells are also good precautions. The traveler should keep comfortably warm and avoid overeating and eating rich foods.

For those traveling by air, adequate hydration and small, easily digested meals taken during the flight help to prevent airsickness. The passenger who experiences motion sickness may benefit from reclining in the seat as far as possible and closing the eyes.

Carsickness is often relieved if the journey is interrupted for short walks in the fresh air and by keeping a window open. Children will frequently find it helpful to glance down, and to refrain from reading. Tobacco smoke can also be an aggravating factor.

En cuanto a su naturaleza discursiva, el texto oral se podria definir como un constructo poetico, dado que en su produccion se implican elementos paralinguisticos--como la proxemia, la kinesia, la entonacion y el ritmo--que se suman a la dimension pragmatica de la puesta en escena, cuando en una dinamica interactiva el locutor retroalimenta el relato base con la participacion de la audiencia o con sus propias preguntas retoricas que intercala para incrementar el suspenso o la emocion del publico (4).
Como se ha reportado previamente, la kinesia paradojal es implicita (Exner, Koschack & Irle, 2002; Mazzoni et al., 2007), implica aprendizaje (cf.
Por lo que respecta a la postura, esta es otra de las grandes categorias que integra la kinesia y que alude a la forma que se adopta dentro de un espacio (Villahizan, 2007: 51).
GLNT has previously commercialized Kinesia a system of wearable sensors and mobile apps for assessing PD and other movement disorders.
El 55% de la transferencia restante corresponde a la proxemica y la kinesia, formas en las que las personas utilizan el espacio o los movimientos corporales para comunicarse, incluyendo la expresion facial, el movimiento ocular y la postura, entre otros.
These findings, and the compelling effects we have observed in using simple techniques to produce optical flow in the peripheral visual field, suggest kinesia paradoxa may work by enhancing visual feedback about self-motion.

En definitiva, puede decirse que en la comunicacion cara a cara, a traves de los tres elementos que constituyen la CNV (kinesia, paralinguistica y proxemica), es decir, por los gestos de la cara, la entonacion de las palabras o la distancia utilizada con un interlocutor puede conocerse su estado de animo.
