Phobia :: essays research papers

Phobias: Irrational Fear Fear of heights, fear of the number â€Å"13,† fear of spiders, fear of small spaces. All of these fears are considered phobias. While there are many causes of phobias, one theory uses the notion of preparedness in Pavlovian conditioning. This is a way in which people learn to react to certain stimuli.   Ã‚  Ã‚  Ã‚  Ã‚  Scientist and abehaviorist, Pavlov, first discovered this conditioning while experimenting with dogs. He could reliably predict that dogs would salivate when food was placed in the mouth through a reflex called the â€Å"salivary reflex† in digestion. Yet he soon realized that, after time, the salivary reflex occurred even before the food was offered. What Pavlov discovered was first order conditioning. In this process, a neutral stimulus that causes no natural response in an organism is associated with an unconditioned stimulus, an event that automatically or naturally causes a response. This usual association causes the response to the unconditioned stimulus, the unconditioned response, to transfer to the neutral stimulus. The unconditioned stimulus no longer needs to be there for the response to occur in the presence of the formerly neutral stimulus. Given that his response is not natural and has to be learned, the response is now a conditioned response and the neutral stimulus is now a conditioned stimulus. Hence, certain individuals are more equipped to learn some things easier than others are. This ability is known as preparedness. In Pavlov’s experiment the tone was the neutral stimulus that was associated with the unconditioned stimulus of food. The unconditioned response of salivation became a conditioned response to the newly conditioned stimulus of the tone.   Ã‚  Ã‚  Ã‚  Ã‚  Considering the two phobias: fear of the number â€Å"13† and fear of heights, the latter is most likely to have been produced by Pavlovian conditioning. This is due to the fact that more people are likely to have obtained preparedness to be afraid of this. There are numerous stories and movies that contribute to this irrational fear. Hence, people are more willing to accept the conditioning and become afraid of high places. This would not be hard to condition into anyone, since it is so commonly feared. Also, the fear of the number â€Å"13† is much more irrational than a fear of heights. Falling from a high place is much more likely than being injured by a number. Thus, preparedness and Pavlovian conditioning most likely caused a fear of heights.   Ã‚  Ã‚  Ã‚  Ã‚  In conclusion, phobias can occur through different causes, but Pavlov discovered one theory.

DNA sequencing Essay

1 How can scientists identify specific bacteria when they are amplifying and studying the same region of DNA in each species? Specialist or doctors compare the nucleotides of the DNA sequences to specific bacteria. 2 Why is PCR used in the process of DNA sequencing? Used to make small segments of DNA. To analyze DNA more DNA is required to attain proper results. 3 How can the DNA sequencing technique shown in the virtual lab be used to identify other classes of pathogens, such as viruses? The same process can be performed by entering parts of the sequences into the database. 4 Explain how sequence data and information about patient symptoms led you to diagnose Sue’s illness. My partner and I looked up different diseases that could be causing Sue’s symptoms until we came across 3 strong matches. Then the disease database testing identified which disease it was. 5 How can DNA sequencing be used to identify genetic risk for certain diseases and disorders? DNA sequencing can be used in family history to find mutations that can cause health problems in the future, how medical history affected the person or diseases that complicated the body. 33. The possible people who could have gotten meningitis from Sue are Jill, Marco, Sue’s friend that she visited at the other University who may have passed along, Maria and Maggie. 34. To proceed with the procedure sue will need to go to the hospital to get treated right away and take antibiotics to cure her disease but antibiotics doesn’t always work with some peoples immune systems. Sue and anyone else she contacted with or know with meningitis symptoms should go to the hospital right away or they can be dead in 24hrs or so. Symptoms of  meningitis: fever, vomiting, headache and feeling unwell. Red ticks show symptoms more specific to meningitis and septicemia and less common in milder illnesses. Limb pain, pale skin, and cold hands and feet often appear earlier than the rash, neck stiffness, dislike of bright lights and confusion.

Shrimp Cultivation

1. Shrimps cultivation has been found to have an impact on the socio-economic and the environment through many studies conducted all over the world. Studies in India showed shrimp cultivation to cost nearly two times the annual earnings of those regions. Moreover the process of shrimp cultivation leads to contamination of fresh water which negatively impact healthy water and reduces the coastal lines which makes coastal regions more prone to hurricanes and tornadoes. 2.The shrimp industry benefits three to four million â€Å"mostly poor† Bangladeshis while providing livelihood directly numbering some 11, 50,000 people. In 2007-2008, a total of 2, 23,095 Metric ton shrimp produced in Bangladesh that contributes 19,567. 90 core taka in the GNP. There is ample demand in the international markets for shrimp and Bangladesh is blessed with an environment friendly for shrimp production. So obviously, the shrimp industry has a huge potential for Bangladesh.Through various studies it w ere also found that shrimp industry did increase the income levels of the people and help them to enjoy a better standard of living. 3. Shrimps cultivation in also observed to have impacts of the social structure which leads to increased migration, social conflict and degradation of health. Moreover, it also cause impact on the bio-diversity, mangrove forest, soil and marine species, salinity, degradation of land and de-stabilization of coastal ecosystems. Bangladesh has been predominantly an agricultural based nation.Degradation of agricultural land will directly affect the food security and livestock of many people. Moreover as Bangladesh is a riverine nation saline waters for shrimp ponds can seep to all the other river bodies and contaminate the waters. 4. Shrimp Industry usually have a limited life-span of about 10 years observed in Bangladesh, Thailand and India. Shrimp farms located in Sunderbands, Khulna, Bhola, Bagerhaat and Barisal also encounter such short life-span. 5. B angladesh shrimp cultivators mostly us extensive to super-intensive shrimp farming techniques.These methods are very harsh and have serious crippling effects on the bio-diversity and the mangrove coastlines. Of about 35% of the world’s mangrove forests have been cleared due to this. 6. Unregulated shrimp farming and improper land zoning legislations have led to social uses such as land grabbing, improper land use and impairment for other fisheries cultivations. Shrimp cultivation have also seen uneven wealth distribution which eventually lead to further societal disputes.

Benefits to Running Bleachers Essays

Benefits to Running Bleachers Essays Benefits to Running Bleachers Paper Benefits to Running Bleachers Paper Athletes, along with others trying to get into shape usually incorporate running bleachers into their exercise routines. This activity has a variety of health and physical fitness benefit. One obvious benefit is the ability for body to develop more efficiently than running on a flat surface. Another benefit is the increase of the heart rate. The heart rate increases because the activity is much more intense than running regularly or jogging. Jogging bleachers requires the exercise to be performed at a higher intensity. This type of workout helps to teach an individual’s cardiovascular system to recovery quickly. This is because after going up the bleachers and resting for a few seconds, the body needs to be ready to be able to work hard again once it is time to run back up. This workout is known as a cardiovascular exercise which is effective in burning calories. This helps to increase the body fat loss and allows the heart rate to elevate for at least 30 minutes. A big reason why most athletes run bleachers is because of its ability to increase leg power. In certain sports, such as basketball, soccer, football and track, leg power is necessary to better the performance of the player. Climbing up the bleacher requires the quadriceps and glute muscles in the legs to push off each step with force. Running bleachers also puts more of a variety into an average person’s workout. This prevents muscles from adapting and allows them to continue development. For runners, finding a set of bleachers to run can be considered a break from their same daily route, which will keep them from becoming tired. For those who are not runners, bleachers will most certainly help to work out the muscles throughout the legs. Although running bleachers can be considered cruel punishment in gym classes, it is an effective exercise that keeps the heart healthy and the legs muscular.

Certainly good luck (kouun) is elusive. Consider that Summer has had malaria; her little brother, Jaz, is friendless; her parents have to fly to Japan to take care of elderly relatives; and her grandmother (Obaa-chan) and grandfather (Jii-chan) must pay the mortgage by coming out of retirement to work for a custom harvesting company. When the siblings accompany their grandparents on the harvest, Summer helps her grandmother, a cook, while Jaz is Jaz: intense, focused, and bad-tempered. At first, things go reasonably well, but then Jii-chan becomes sick, and it appears that it might be up to Summer to save the day. Will she succeed? Kadohata has written a gentle family story that is unusual in its focus on the mechanics of wheat harvesting.   (Grades 4-8) Starred Review,   Booklist Michael Cart Finalist for the young peoples literature award included: Kathi Appelt, The True Blue Scouts of Sugar Man Swamp   (Atheneum Books for Young Readers/Simon Schuster) Tom McNeal, Far Far Away (Alfred A.

Describe and explain the main functions of prices in a modern Essay

Describe and explain the main functions of prices in a modern competitive market economy PLUS MORE QUESTIONS - Essay Example This is a signal to the supplier to expand their production in order to meet higher demand. Further, in case of excess supply, price factor also plays an important role to eliminate the excess supply. The signalling function of price can be discussed more briefly by using the following diagram. It can be seen from the Figure-1, as demand for good-Q increases, supplier of the goods can earn higher revenue and profit by selling it at higher price per unit. Thus, increase in market demand leads to expansion of market supply. Further, Figure-2 shows an increase in market supply causes fall in the relative price of good-Q and expansion of the market output along with the market demand curve. By utilising the signalling function of price, consumers are able to transmit expression of the preference or important information about changing needs and wants, to its customers. When market demand is high, price acts as the motivational factor to increase production, as supplier can earn higher profit by increasing their production. Similarly, when demand is low, it signals suppliers to contract their production. In market mechanism, suppliers actually control their production on the basis of price fluctuation (Mas-Colell et al. 2004). Price also plays an important role to ration the scarce resources. It helps to allocate the scarce resources in an effective way, when demand in the market over strips the supply. When there is shortage of product in market, the price rises. Thus, only those people, whose willingness to pay is effectively high, purchases the product. It helps to eliminate consumers having low willingness to pay. In this context, it can be cited that, auction plays a crucial part to allocate resources in an appropriate manner and clears the market. In economics, the term demand increase reflects increase in the ability and willingness on the buyers to buy a good or services at pre-existing

Industries and technology both have hurt and helped our enviornment Essay

Industries and technology both have hurt and helped our enviornment - Essay Example The first wave took place in the late 1700’s, bringing industrial improvements to textiles, iron, water and power systems and mechanization. The second wave brought about steam power, trains and steel production. Next, in the 1900’s, came electricity, chemicals and cars. By the middle of the 20th century, the emerging innovations were petroleum, the space race and electronics. In the most recent years, known as the digital age, society has witnessed the development of computers and other electronic devices. All these innovations have contributed to the development of society. However, the creators of these products did not initially think about the amount of waste that would be generated through the manufacturing of these products and what would happen to these products once they became obsolete. Increasing awareness of the effects of manufacturing on the environment has lead to the development of waste management processes and green engineering. It is not only the issue of emissions, but also the disposal of obsolete vehicles that we have to worry about. These emission and hazard waste disposal issues are common concerns for all manufacturing facilities. An example of this is the plants in the state of New Jersey that refine oil. They produce products that are very much needed in modern society. However, they also produce waste that is difficult to dispose of and can be damaging to our environment. To preserve our environment requires our manufacturers take steps to implement green engineering principles into their processes and abide by the rules and regulations put forth by the EPA and other agencies. On the other hand, consumers must also learn to conserve and use products less wastefully. New technologies and industries are created to meet the demands of people and to continuously try to lower the cost of products. Such innovations sometimes have undesirable effects on our global environment. For example, chlorinated fluorocarbons (CFCs) were
