How to Train Your Pet

Process Essay: How to Train Your Pet

Have you ever wonder how the animals you see on TV and in moves are trained to perform such amazing tricks? Many of their trainers use a technique based on the teaching methods developed by behavioral psychologists such as B. F. Skinner. Skinner studied techniques for reinforcing desired behaviors in animals. Animals can be taught many sophisticated tricks using Skinner's techniqes. If you want to teach your pet do do a trick, you must understand the techniques pyschologists call "shaping." Shaping manes reinforcing, or strengthening, behaviors that you want to encourage. Here is how you can use his techniques to train you pet to do tricks.

The first thing you must do is choose your subject. You can pick any household pet, such as a cat, hamster, parrot or dog. For example, suppose you want to teach your dog to do a trick. Next, choose a reward. Food is usually the easiest reward to use. Keep in mind that in order for food to be an effective reward, you dog must be hungry. Don't try to teach him a new trick after he has eaten a big meal. Also, a reward is most effective when it is given at the same time the dog performs the desired trick. Since you will not not always be able to give the dog food as quickly as you would like to, you will need to develop a "conditioned reinforcer". You can do this by connecting the food with something else, such as ringing a bell. In this case, the sould the bell makes is the conditioned reinforcer.

You are now ready to begin conditioning the dog to respond to the bell. Get out about 40 small dog biscuits. Toss a few of them to your dog, one at a time, at a rate of about one or two biscuits a minute. As soon as the dog begins eating the biscuits, ring the bell and then throw him another biscuit. Wait about 30 seconds and then repeat the steps. When you ring the bell, do not make any other sound or movement. Give the biscuit only when the dog is standing in the place where he gets his food. When your dog reaches the point where he goes to the food plate whenever you ring the bell, you are ready to begin teaching him the trick.

At this point, you need to choose the trick you want to teach. An easy trick is teaching your dog to roll over. Shape the dog's behavior by reinforcing anything that resembles the behavior you are trying to teach. Begin by reinforcing any attempt to lie down. Then reinforce any movement of his body when he is lying down. Every time you reinforce any of his behaviors that resembles rolling over, immediately give him a biscuit and ring the bell. In this way, he will begin to associate the sound of the bell with the trick. Continue reinforcing closer approximations of rolling over with the biscuits and the bell. During the teaching session, do not touch the dog, talk to him, or in any way distract him. A normal dog, according to Skinner, will learn the trick within five minutes.

As you can see, it is really not very difficult to train your pet to do a trick. It is only a matter of a little time and some effort. Once you have established a conditioned reinforcer, you can easily teach your dog a new trick by shaping his behavior. Remember, though, that if you want to teach you dog another trick, you must eliminate the first behavior by no longer reinforcing it. Eventually, he will stop rolling over and will be ready to learn something new.

Progeria – “accelerated aging disease”

In my previous class, public speaking, we were tasked to make an informative speech...some can make a speech on how to make something, like to make a rose winem by showing the steps..But i decided to give an informative speech about progeria...I got some info here, and others were added by me...

--on the photo: 8 year old Fransie Geringer of South Africa, left, and 9 year old Mickey Hays of the United States—have the premature aging disease, progeria. Mickey Hays is an actor and appeared on the Aurora Encounters. He died when he was 20 years old and is know to be one ofthe longest survivors of progeria.




Progeria – “accelerated aging disease”
Imagine for a second that you are 10 years old. Your friends call you up to go out and play but you can't because you have a painful case of arthritis that hurts with every step you take. Or, your chronic heart disease disables you from being able to breathe easily. These conditions are just a few that a child with Progeria may suffer from. Progeria is also known as Hutchinson-Gilford Syndrome. It is an extremely rare aging disease that causes a child to age up to eight times faster than normal. It is also know as the “accelerated aging diseases. I first became interested in Progeria when I have read it from an article in Nature.The disease affects between 1 in 4 million and 1 in 8 million newborns. Currently, there are 51 known cases in the world. Most people with progeria die at around 13 years of age.
The condition was first identified in 1886 by Jonathan Hutchinson and in 1987 by Hastings Gilford. The condition was later named Hutchinson-Gilford Progeria syndrome (HGPS). However until now scientist have yet found a medicine for this condition. In the beginning, Progeria was studied as a disease that included the process of normal aging, just at an incredible rate. This is no longer be true because Progeria does not affect all of the body's organs. For instance, there is no evidence of aging in the central nervous system. A few are mentally retarded, but most have normal intelligence and may even be advanced. A child with Progeria is just a normal seven-year-old in a 70-year-old body!
The cause of this rare disorder is not yet fully understood. In 2003, researchers announced the discovery of a single gene mutation responsible for Hutchison-Gilford progeria syndrome. The gene is known as lamin A (LMNA), which makes a protein necessary to holding the center (nucleus) of a cell together. Researchers believe the genetic mutation renders cells unstable, which appears to lead to progeria's characteristic aging process. Unlike many genetic mutations, Hutchison-Gilford progeria isn't passed down in families. Rather, the gene change is a chance occurrence that researchers believe affects a single sperm or egg just before conception. Neither parent is a carrier, so the mutations in the children's genes are new (de novo).
          Individuals with Progeria appear normal at birth. It is not until about the age of one that signs become evident. Growth is extremely stunted, and they may only reach the height of a normal two or three-year-old. It is very unlikely that they will grow taller than a normal five-year-old will, even though they have the physical characteristics of a 60-year-old.
According to the Hutchinson-Gilford entry of the Electronic Textbook of Internal Medicine, there are many signs to detect the presence of Progeria. These signs include: (visual aide) baldness, prominent scalp veins, beaked nose, receding chin, prominent eyes, a narrow chest, a protruding abdomen, an enlargement of the spleen, and the absence of eyebrows and lashes. The sex organs also remain small and underdeveloped, and they are not able to reproduce. They often have relatively large heads with small faces and crowded irregular teeth. Individuals with Progeria often develop diseases related to aging, such as arthritis and heart disease. Another common cause of death is angina pectoris, which is a condition in which there is a sudden decrease of blood in the heart muscle. Progeria is extremely rare. In my speech, I have informed you of the extremely rare aging disease known as Progeria.

Filipino Debate: PAKSA: ANIM NA TAONG LANG ANG TERMINO NG ISANG PANGULO (Affirmative)

oI am just cleaning the files in my pc, when i saw one of my homeworks in my Filipino class, i think this was about 2 years ago..the teacher gave our group to debate about the term of the president....(6 years term)..i was tasked to debate in affirmative side, which means i am in favor of the 6 years term... it was bit hard to debate in Tagalog...i needed to translate the constitution and my debate as well from English to Tagalog..

here is my tagalog debate, i will post the english translation when i have time...

PAKSA: ANIM NA TAONG LANG ANG TERMINO NG ISANG PANGULO
(Affirmative)
Magandang Hapon sa ating lahat!!!
Malugod kong binabati ang lahat ng nandito. Nagpapasalamat ako sa pagkakataong ibinigay niyo upang ating mapag-usapan ang pagkakaroon ng anim na taong termino ng President ng Pilipinas.

Ako’y nakikiayon sa ating 1987 Constitution na ang termino ng pangulo ng Pilipinas ay anim na taong lamang dahil sa mga sumusunod na kadahilanan:
  • Una: Kapag ang ating pangulo ay may anim na taong termino mas magagawa niya ng mabuti ang kanyang mga tunkulin dahil magkakaroon siya ng sapat na panahong upang maisakatuparan ang mga programang nasa plataporma niya. Halimbawa: Binabalak ng Pangulo na magpatayo ng mga tulay at kalsada. Ang pagtatayo ng mga tulay at kalsada ay nangangailangnan ng ilang taon. Kung mahaba ang termino ng Pangulo, nakakasigurong matatapos ang mga imprastrakturang ito. Magkakaroon din siya ng sapat na panahon upang maisagawa ang mga batas na makakatalong sa mga programa na binabalak pa lamang at mga programang kasalukuyang ginagampanan. Halimbawa: Binabalak ng Pangulo na bignyang ng malaking pansin ang pambansang kalusugan. Kinakailangang may sapat na panahon upang mapagkasunduan ito ng kongreso at senado senado sa loob ng termino ng pangulo.
  • Pangalawa: mababawasan ang pabagobago ng mga opisyales na napasailalim sa pangulo kung ito’y manunungkulan ng anim na taon dahil tuloy-tuloy ang pakikitungo ng goberyo at ng mga mamayan. Kung ang ating pangulo ay magkakaroon ng anim na taong termino mababawasan ang kalituhan at problema dahil ito’y maayos na ng mga kaslukuyang opisyales. Sa pamamagitan ng pagkakaron ng ang ating pangulo ng 6 na taong termino, nakakatipid ang bansa sa mas bawas na botohan. Malimit mangyari ang paghihimpil o pagbabagal ng komersiyo tuwing may eleksiyon. Higit na tuluy-tuloy ang paglakas ng pangangalakal. Kung tuluy-tuloy ang komersiyo, mananatiling matatag ito, at makikinabang ang buong bansa.
  • Pangatlo: Sa pakikipagpanukala ng ating pangulo sa ibang bansa, higit na mapapabuti ang kaugnayan ng ating bansa sa kanila dahil mayroong personal na kaugnayan ang ating Pangulo at sa ibang bansa. , kabilang na dito ang pandaigdigang samahan.
Narito ang nakasaad sa ating konstitusyong magpapatibay na dapat ang isang pangulo ay manunungklulan ng anim na taon

Artikulo VII

SEKSYON 4. Ang Pangulo at Pangalawang Pangulo ay dapat mahalal sa pamamagitan ng tuwirang boto ng sambayanan para sa taning na anim na taon na magsisimula sa katanghalian ng ikatatlumpung araw ng Hunyo na sumusunod sa araw ng halalan at magtatapos sa katanghalian ng gayon ding petsa pagkaraan ng anim na taon. Ang Pangulo ay hindi magiging karapat-dapat sa ano mang muling paghahalal. Ang sino mang tao na humalili bilang Pangulo at naglingkod nang gayon sa loob ng higit na apat na taon ay hindi dapat maging kwalipikado sa paghahalal sa katularing katungkulan sa alin mang panahon.
