Cause And Effect Of Motion Sickness - 1415 Words

Experiencing illness and an uncomfortable feeling due to motion is nothing new to mankind. The feeling of motion sickness can be traced back to Hippocrates, who wrote that â€Å"sailing on the sea shows that motion disorders the body† (as cited in Rine, Schubert, Balkany, 1999, p. 950). Its roots are laid in man created environments experienced by the human body, such as boats, planes, cars, theme park rides, etc. It is through these creations that the human head experiences forced movement in a gravity field or an unnatural visual field that moves without human input. In most cases, if a person keeps their head motionless and their eyes closed, they will not experience any motion sickness. An exception to this rule is during a non G situation, such as weightlessness in space, where there is no movement of the local gravity field. In this environment a human may incur motion sickness. This demonstrates the gray area when causes of motion sickness and susceptibility are discussed. The wide range of human disorders and environmental tolerances due to psychological and physiological characteristics, makes for a wide range of exposure conditions. Specifically, humans with inner ear disorders can experience motion sickness due to small head movements (Jackson, 1994). Common symptoms they might experience are: nausea, vomiting, headache, diminished cognitive ability and fatigue following the event. Experiencing these impairing effects while driving a car or worse pilotingShow MoreRelatedBullying And Cyberbullying933 Words   |  4 Pagesfollow the link) and identity theft (when hackers steal account information and social security numbers) are very real concerns with banking online (Root.)

Is Depression Caused by Nature or Nurture Essay - 685 Words

The general public believe that depression is caused by both nature and nurture factors. A majority of the public believed that nurture has a greater influence on whether the person gets depression or not. Uni-polar depression is when a person is always in a very low mood which would last at least 2 weeks to be fully diagnosed with depression. A person who has unipolar depression usually do not see the positive side of things. Bipolar depression is when a person has sudden mood swings from really low mood to sudden high mood, bipolar depression is harder to diagnosis than unipolar depression. Depression is thought to involve many genes. Biological psychologists believe that a person usually develop depression because of genetic†¦show more content†¦There is also strong evidence that depression is caused by drugs or alcohol abuse which ultimately changes some genetics of the person For example cocaine affects neurotransmitters in the brain which could have an affect of developing depression. Biological explanations also include the fact that depression can be developed by several genes becoming mutated/changed because of x-rays, chemicals or ultra violet light. Biological explanations however ignore the fact that nurture can play a significant role in the development of depression for instance some people develop depression (unipolar or bipolar) after a tragic event such as a death of a close family member. Therefore how can those individuals have genetic changes that only get triggered when something horrible happens in the person’s life time? Research with adopted twins have also shown children who have depressive symptoms have the same as their biological parents therefore showing that depression can be inherited (Wender 1968.) Neurochemical factors (chemical changes) has also been involved in developing depression, there is good evidence that if neurotransmitters such as: serotonin, noradrenalin and dopamine is increased or decreased in large amounts it has a great effect on the synapses therefore if there is an imbalance of neurotransmittersShow MoreRelatedNature vs. Nurture1218 Words   |  5 Pagesdifferent people with different interests and preferences?

Training and selective stimulus control in rats Essay Example

Training and selective stimulus control in rats Paper The aim of the experiment was to show that rats demonstrated stimulus discrimination and selective stimulus control during operant conditioning. The first hypothesis was the subject would learn to discriminate between the VR16 conditions that signal reinforcement and the EXT conditions. It was also hypothesised that the stimulus used to discriminate between VR16 and EXT would either be the light or the tone, not a combination. The participant in this experiment was a 16-month-old, female, Spague Dawley albino rat that was randomly selected from a group of 20. The apparatus used was an operant chamber, which delivered two stimuli (a light and a tone) to the subject, and a reinforcer of diluted condensed milk. During the first week of experimentation the subject underwent discrimination training, this was followed by a series of probe trials in the second week. The results from the first week showed the subject learned that no reinforcement was given during EXT, because the rate of responding decreased. The second weeks results showed that high tone was the stimulus used to discriminate between the stimuli. These results supported both the hypotheses, and it was concluded that rats do demonstrate stimulus discrimination and selective stimulus control. The major theorists for the development of operant conditioning were Edward Thorndike (1910), John Watson (1914), and Burrhus Skinner (1938) (Huitt and Hummel, 1997). They proposed that learning is the result of the application of consequences following overt behaviour; that is, subjects begin to connect certain responses with certain stimuli. This led Thorndike to conclude that the probability of a specific response reoccurring is changed according to the consequences following the response, and he labelled this learning conditioning (Carlson and Buskist 1997, Huitt and Hummel, 1997).

The consequence was either punishment or reward (Carlson and Buskist, 1997). Thorndike measured the time it took the animal to escape over various trials, and over time he noted that the animals latency to escape decreased consistently until it would activate the lever immediately after being placed in the box (Huitt and Hummel, 1997). The reward of being freed from the box somehow strengthened the association between the stimulus of being in the box and the appropriate action (Huitt and Hummel, 1997). Thorndike concluded that the reward strengthened the stimulus-response associations (Carlson and Buskist, 1997). He then went on to formulate his law of effect, which can be summarised by saying that an animal is more likely to repeat a response if the result is favourable, and less likely to repeat the action if the consequences were not favourable (Carlson and Buskist, 1997). There were two possible consequences of a behaviour, reinforcement or punishment. These could be divided into two sub-categories, positive (sometimes called pleasant) and negative (sometimes called aversive). These could be added to or taken away from the environment in order to change the probability of a given response occurring again (Carlson and Buskist, 1997. Werzburg University). Punishment decreases the repetition of behaviour and reinforcement usually increases the likelihood of response being repeated. A stimulus that acts as an indicator to the subject, suggesting that a reinforcer is available is said to be a discriminative stimulus (Gleitman, 1995). A discriminative stimulus affects the subjects behaviour considerably (Gleitman, 1995), as it influences the likelihood of a response occurring (Carlson and Buskist, 1997). Reynolds (1961) conducted experiments where two pigeons learned to tap a red key with a white triangle. To determine which was the discriminative stimulus, he tested the two birds with either a plain red key or a plain key with just a white triangle. Reynolds (1961) found that the first bird used the red key as the discriminative stimulus and the second bird used the white triangle to discriminate between stimuli. This experiment is also an example of selective stimulus control, where each pigeon selected which stimulus it believed was responsible for producing the reinforcer. To effectively study how a subject behaves in a given environment and to certain stimuli, it was necessary to establish a schedule of reinforcement, which is a set of guidelines saying how often the subject is reinforced (Gleitman, 1995). Stimuli could be presented to the environment according to a schedule of which there were two categories: continuous and intermittent (Gleitman, 1995), or not at all using extinction. Continuous reinforcement simply means that the behaviour is followed by a consequence each time it occurs. Intermittent schedules were based either on the passage of time (interval schedules) or the number of correct responses emitted (ratio schedules). The consequence could be delivered based on the same amount of passage of time or the same number of correct responses (fixed) or it could be based on a slightly different amount of time or number of correct responses that vary around a particular number (variable). This results in four classes of intermittent schedules, fixed interval (FI), fixed ratio (FR), variable interval (VI), and variable ratio (VR) (Gleitman, 1995). [Note: Continuous reinforcement is actually a specific example of a fixed ratio schedule with only one response emitted before a consequence occurs.]. The final schedule was extinction. During extinction, the subject is no longer reinforced for producing a previously reinforced response. Because there is no reward for responding, the frequency of the response decreases until it stops altogether (Carlson and Buskist, 1997. Huitt and Hummel, 1997. Gleitman, 1995). For the purpose of this experiment we used two alternating schedules of consequence (Lab Manual Psychology 111/112, 2002), Variable Ratio of 16 (VR16), where a reinforcer was given after an average of 16 responses, and Extinction (EXT). VR schedule was chosen, as a variable ratio was thought to be the best for maintaining behaviour (Werzburg University).  The aim of the experiment was to demonstrate stimulus discrimination and selective stimulus control in rats, and in turn, give support to past research indicating that learning comes from experience. The subject for this experiment was a female, albino rat, approximately 18 months old. The rat was placed in the operant chamber and subjected to two stimuli, a light and a tone. VR was paired with a dull light and high tone (1000Hz) and EXT was paired with a bright light and a low tone (500Hz) (Lab Manual Psychology 111/112, 2002). By reviewing past research, two hypotheses were formulated. The initial hypothesis was that the subject would learn to discriminate between the VR16 conditions that signal reinforcement and the EXT conditions, and therefore the rates of responding during VR16 would be higher than during EXT. It was also hypothesised that the stimulus used by the rats to discriminate would either be the light or the tone, not a combination (selective stimulus control).

Carnivalism And Its Effect On Literature Essays - Grotesque

Carnivalism And Its Effect On Literature Essays - Grotesque Carnivalism And Its Effect On Literature Carnivalization is the term used by Mikhail Bakhtin to describe the shaping effect on literary genres. The idea of carnivalism is the discourse of structuralism. Carnivalism is the opposite of everything deemed normal. Bahktin describes it as: ...the true feast of time, the feasts of becoming, change and renewal. (45) Carnival originated from the Feasts of the Church. The feasts were a serious, formal occasion in which strict patterns were closely followed. Emphasis was placed on social standing. It was considered a consecration of inequality (45). However, during Carnival, everyone was considered equal. The festivities of Carnival were very popular, everything was turned upside down (the smart become stupid, rich become poor, etc.; fantasy and reality become one). The jolly relativity of all things is proclaimed. (45) Carnivalism is evident throughout literature, but it is very noticeable during the Renaissance. The Socratic dialogue is an example of the earliest carnivalised literary forms. Two of the most familiar forms of carnivalism are Alisoun; the Wife of Bath from Chaucer's The Canterbury Tales and Falstaff, from Shakespeare's Henry IV. Alisoun, asserts her own overbearing assessment of the roles of women in society and relationships. The Wife has often been written off as a shrew-like bombast simply sprouting her dissatisfaction. She is the opposite of what women were expected to be in her time. She seems to take pride in being so contradictory to societal ideals. Falstaff, like the Wife; enjoys being the center of attention and shocking people with his outlandish proclamations. He is a con man, coward, and thief. Although people would never admit it, they secretly enjoy hearing the lewd stories told by the Wife and Falstaff. The Wife and Falstaff could be described as grotesque realism. Grotesque realism has no lower level. It is the dark side of society. The term perfectly describes both characters. They represent the subconscious of people- the things and ideas that people are afraid to say or do. Falstaff and the Wife both use apologia to justify their actions. The Wife has her own unique interpretation of the Bible. She asks where in the Bible is virginity commanded. She also questions the traditional moral values of medieval British culture in asking, ... to what end were reproductive organs made, why are people made so perfectly? Falstaff justifies his actions by saying banish plump Jack, banish all the world. In essence, everyone is just like him; the only difference is that he doesn't hide it. Bakhtin's emphasis on carnival goes against the idea that literature must be unified. He suggests that major literary works may be multi-leveled and resistant to unification. (41) In his essay, Discourse of the Novel, he states when someone else's ideological discourse is internally persuasive for us and acknowledged by us, entirely different possibilities open up.(43) This is the case with the Wife and Falstaff. They represent the idea that life does not have to be so rigid, it is o.k. to bend the rules a bit. The Wife of Bath and Falstaff are examples of carnivalism, grotesque realism, and authoritative discourse. The characters appear to be larger than life when they are actually only one side of the coin of society. Heads shows society as it is expected to be, tails shows life as it really is.

Citas con USCIS para informacin migratoria - INFOPASS

Citas con USCIS para informacin migratoria - INFOPASS Los empleados del Servicio de Inmigracià ³n y Ciudadanà ­a (USCIS, por sus siglas en inglà ©s) pueden ser la mejor fuente de informacià ³n para resolver dudas migratorias generales o para informar sobre estado del caso. Si se desea cerrar una cita para presentarse en una oficina del USCIS se puede hacer desde casa, ingresando por internet en la pgina oficial de este organismo en el apartado de InfoPass. Sin duda esta puede ser una buena opcià ³n para obtener informacià ³n de inmigracià ³n de calidad, aunque conviene tener muy presente que el USCIS nunca va a actuar como asesor legal. Para eso estn los abogados, que cada persona debe elegir libremente, si desea contar con ese servicio. Cà ³mo se cierrauna cita con InfoPass En la pgina del USCIS, hay una opcià ³n en la barra izquierda de la pantalla para elegir el idioma, entre los que estn incluidos el espaà ±ol y el inglà ©s. Debern rellenarse los campos en los que se pide que se escriba el nombre de la persona que va a acudir a la cita, su nà ºmero de telà ©fono, su fecha de nacimiento y el cà ³digo postal (zip code) en el que reside. InfoPass ofrece citas para, aproximadamente, dos semanas despuà ©s. Se puede elegir el dà ­a y la hora que ms convienen, si estn disponibles. Al finalizar el proceso de solicitud de cita, aparecer en la pantalla una confirmacià ³n de la misma en la que se incluye el dà ­a, fecha y lugar en el que hay que presentarse. Esta informacià ³n debe imprimirse y llevarla a la entrevista con el oficial del USCIS. Si se pierde la hoja, debe imprimirse otra volviendo a entrar en Info Pass. Si se pide una cita para ms de una persona, el sistema no admite que se pueda cerrar una seguida de la otra. Deber esperarse al menos media hora para realizar las citas. O tambià ©n es posible hacerlo inmediatamente si se utiliza o bien otra computadora o bien un navegador distinto. Por ejemplo, utilizar Explorer o Firefox para la primera vez y Chrome para la segunda.  ¿Por quà © Info Pass no me permite cerrar una cita? Es relativamente comà ºn que cuando se intenta utilizar Info Pass se obtiene un mensaje de error. Esto es porque el sistema est al mximo de su capacidad. Se puede intentar varias veces, hasta que funcione o bien se puede intentar en las horas de la madrugada. Menos personas lo intentan en esos momentos lo que hace ms probable que el sistema funcione adecuadamente.  ¿Quà © pasa si surge un imprevisto y no puedo acudir a la cita con el USCIS? Se puede cambiar el dà ­a y la hora de la cita. Basta con entrar de nuevo en la pgina de INFOPASS y hacer los cambios necesarios. Se necesita tener a mano la hoja impresa con la confirmacià ³n de la cita inicial, ya que à ©sta contiene un nà ºmero de confirmacià ³n que es necesario saber para hacer el cambio de cita para la entrevista en el USCIS.  ¿Quà © se debe llevar a la cita con el USCIS? 1. Todos los documentos relativos a la pregunta que se quiere formular. Si el original est en un idioma distinto al inglà ©s, debe traducirse. 2. La hoja de confirmacià ³n de la cita de Info Pass. 3. Una identificacià ³n oficial como por ejemplo la green card, el pasaporte, el I-94, la licencia de manejar del estado en el que se reside, el permiso de trabajo o cualquier otro I.D. emitido por las autoridades americanas. 4 .Es posible ir acompaà ±ado de una persona que haga de intà ©rprete, si no se entiende o habla bien el inglà ©s. Puede ser un familiar o un amigo, pero tiene que ser mayor de 21 aà ±os. Presentarse sin cita en una oficina del USCIS Si se necesita hacer la consulta con carcter de  urgencia  siempre es posible acudir a las oficinas locales del USCIS y esperar en fila hasta que un oficial pueda atender la pregunta.   A veces la  espera  dura horas e incluso es posible que se deba volver al dà ­a siguiente y hacer la espera de nuevo. Esto ocurre cuando el mismo dà ­a y en la misma delegacià ³n de Inmigracià ³n hay un nà ºmero muy grande de personas esperando para hacer su consulta. Otras formas de obtener informacià ³n migratoria Si la pregunta se refiere al estatus de un caso pendiente, el proceso a seguir es otro. Permitià ©ndose consultas electrà ³nicas, telefà ³nicas y, por supuesto, en persona. Si la duda se refiere a los tiempos medio de demora para trmites, estas  son las demoras migratorias para peticiones de green card  de familia, trmites de visas, solicitudes al USCIS, y retrasos en las cortes. Si lo que se busca es informacià ³n sobre el rà ©cord migratorio, hay varias formas de obtenerlo, dependiendo de quà © oficina tenga la informacià ³n.   Por otro lado, si lo que se desea es encontrar a una persona que puede estar detenida por Inmigracià ³n, entonces el lugar correcto para preguntar no es USCIS, que no se ocupa de esos asuntos. El camino correcto es contactar con ICE. Finalmente, los mexicanos sin importar su estatus migratorio en los Estados Unidos pueden marcar gratuitamente a un telà ©fono pagado por el sistema consular de su paà ­s. Brinda ayuda importante sobre cà ³mo obtener informacià ³n e incluso realizan ellos gestiones. Finalmente, este es un listado con 10 telà ©fonos en los que se puede resolver dudas migratorias, denunciar fraudes u obtener otra informacià ³n oficial. Consejos importantes para indocumentados Si no tiene todos los documentos en regla y se est ilegalmente en los Estados Unidos se aconseja que no se presente  voluntariamente en el USCIS para hacer una pregunta. Consulte a un abogado de inmigracià ³n o con una organizacià ³n reputada de apoyo a migrantes con servicio de asesorà ­a legal. La razà ³n para no presentarse en las oficinas en las oficinas del USCIS es que se trata de un edificio federal y pedirn que toda persona se identifique con un documento que de un modo u otro muestre estatus migratorio en el paà ­s. Podrà ­a darse el caso de que se arrestase al migrante indocumentado.
