Nature Vs. Nurture Nurture - 901 Words

As a child, I loved lying on the living room floor, crayons in hand, creating a masterpiece for my mother to camouflage our refrigerator. Throughout my childhood and adolescent years, I was fortunate enough to realize my creative potential. I often think about what exactly attributed to my creative ability. For a long time the proverbial nature vs. nurture question has sparked quite a debate. I hold the belief that nature vs. nurture is a zero-sum game. We essentially enter this existence, a lump of clay that needs molding in order to take form. So, I believe my creative abilities can be attributed to the sum of our genetic predisposition, the nurture of our mind, and the dynamic of both nature and nurture, with nurture being the predominant influencing factor. In psychology, nature refers to the inherited genetic characteristics and predispositions that influence development. Some inherited characteristics appear in virtually everyone. For instance, almost all children are born with the capacity to learn to walk, develop a language, imitate others, use simple tools, and deduce how other people view the world; therefore, all children have a set of universal genetics that, when coupled with a reasonable environment, allow them to develop as functioning human beings. I am a firm believer that our genetic makeup has a tremendous amount to do with our skills and abilities. I, personally, feel my creativity can be attributed to the long line of writers, artists, andShow MoreRelatedNature Vs.

Analysis Of Where The Sidewalk Ends A Poem Analysis

Research Paper and Poem Analysis: Shel Silverstein â€Å"Where the Sidewalk Ends† A poem analysis Have you ever been scared to cross the street when you were a child? Have you ever sat and stared at the paint that is on the road and wondered if that is what is keeping you safe? Shel Silverstein’s poem, â€Å"Where the Sidewalk Ends† a three stanza poem, and is in the view of a child. It is very descriptive about what the child is seeing also. I believe that Silverstein was trying to get kids to understand that the lines of the street are to protect them, and that he loved kids, because he wrote so much poetry and so many books for children. In the first stanza of â€Å" Where the sidewalk ends,† Silverstein is explaining the scene, with nice descriptive words, â€Å"There is a place where the sidewalk ends / and before the street begins, / and there the grass grows soft and white, / and there the sun burns crimson bright, / and there the moon-bird rests from his flight / to cool in the peppermint windâ₠¬  (1-6). The word choice and descriptive language definitely brought me back to a time when I was younger. Silverstein obviously didn’t follow any set rules, he made it his very own. The place I think he might be talking about is the borderline between night and day, or sun and the moon. It’s the middle of two things that are opposites. The second stanza mostly focuses on explaining that if you follow the guidelines then you will not be harmed.

This instance survey is about an 80 old ages old male with symptomless abdominal aortal aneurism who presented to his GP with other symptoms unrelated to abdominal aortal aneurism. The writer will analyze the diagnosing of his aneurism, the mode used, the intervention and direction. Diagnosis and intervention tracts shall be followed ; analysis and comparing to other tracts shall be done to see which is the most effectual and accurate in the diagnosing and intervention of abdominal aortal aneurism. We will write a custom essay sample on Abdominal Aortic Aneurysm Health And Social Care Essay or any similar topic only for you Order Now Patient confidential information shall be maintained throughout this essay, therefore in line with the codification of professional behavior, Nursing and Midwifery Council ( 2008 ) . Case study 80 old ages old, Mr X, of height 5 pess 8 tall who weighted 50 kilograms presented to his GP on the 6th of February 2010 with 6 yearss history of irregularity. During physical scrutiny a throbing mass was noted in his venters. The patient had no symptoms related to aneurysm, such us back or abdominal hurting. The GP discovered during conversation with Mr X that his brother died from rupture AAA a twelvemonth ago. Mr X smokes 3 battalions of coffin nails daily. His past medical records showed that, he had chronic clogging pneumonic disease, high blood pressure, ischemic bosom disease which he had a beltway surgery 15 old ages ago. He besides had an MI 2 old ages ago holding had transdermal conary intercession ( PCI ) to circumflex and right coronary arterias. The GP suspected that Mr X had an AAA and referred him for ultrasound scan to govern out the size of AAA. The ultrasound scan was conducted two hebdomads after seeing the GP. The scan revealed an aortal aneurism below the degree of the nephritic arterias mensurating 5.99 cm A-P diameter. Mr X was referred to a vascular sawbones who recommended a CT scan to look into the extent and anatomical construction of the aneurism to see Mr X ‘s suitableness for endovascular repai Computer Tomography Angiogram aorta was performed a hebdomad after the ultrasound scans. CT angiogram with contrast showed a big infra-renal abdominal aortic aneurism which measures maximally 6 centimeter in diameter. It besides demonstrated good infra-renal cervix. Ultrasound of the venters showing an infrarenal aortal aneurism steps 5.99 centimeter. ( Local NHS Trust 2010 ) Axial CTA with contrast of the venters demoing infrarenal aortal aneurism mensurating 6 centimeter ( pointers ) with partial calcified integral wall ( Local NHS Trust 2009 ) The sawbones so referred Mr X for an elected vascular surgery because his aneurism was big and carried a high hazard of rupture and decease. One hebdomad before his surgery, Mr X had a chest X ray, blood trial and EKG which were all normal. On the twenty-four hours of admittance, his pulsation was 68BP/min and regular with a blood force per unit area of 140/80 mmHg. The below tabular array shows pre-assessment blood probes done. Blood Test Mr X ‘s consequence Normal Laboratory Test Values Entire white blood cell count 6.56 M/mcL 3.8 M/mcL to 5.6 M/mcL hemoglobin 14 g/dL 11 g/dL to 18 g/dL Platelet count 160 150-400 Red blood cell count 5 M/mcL 3.8 M/mcL to 5.6 M/mcL Bureau of intelligence and research 1.1 0.9-1.2 Blood urea N 6.86 mg/dL 6 mg/dL to 23 mg/dL Creatinine 98 mg/dL 0.6 mg/dL to 15 ng/dL ( Tinkham 2009 ) Preoperative appraisal was done to give Mr X ‘s sawbones a image of his overall wellness position. A complete blood count was performed to look into for the presence of infection, ensured an equal ruddy blood cell volume and regulation out serious haematological abnormalcy. Electrocardiography ( ECG ) was performed to measure cardiac arrhythmias and diagnose cardiac upsets such as myocardial infarction. Chest X ray was done to measure the presence of infection, bosom failure, emphysema and other status that may act upon surgical result. Creatinine and urea were performed to place job with nephritic clearance preoperatively.INR trial was done to guarantee coagulating ability before surgery. The International Normalized Ratio ( INR ) was done to guarantee blood coagulating ability before surgery On the 30/ 4/2010, Mr X underwent an endovascular aortal fix and was transferred to intensive attention unit while proctor his status for 3 yearss. He was discharged and had a wholly recovery after a month. Mr X had a follow up postoperative ultrasound and field movie x beam of venters. X beam and ultrasound was conducted at 1and 6 months to look into the place of the stent transplant and endoleaks. However, the scan and ten beam showed no grounds of any complication. Plain skiagraphy of venters at 1 month the unity and migration of Zenith stent transplant Raad ( 2010 ) Discussion AAA is a comparatively common and potentially dangerous status associated with old age. The bulk of abdominal aortal aneurisms do non do any symptoms and hence diagnostic is frequently missed. In many instances, the exact cause of aneurism is still ill-defined. However, harmonizing to Baker ( 2009 ) , the primary cause of aortal aneurism is atherosclerosis and other factors for case, male over 65 old ages, smoke, a positive household history, COPD and high blood pressure contribute to the hazard. An probe of Mr X ‘s AAA was done during a physical scrutiny of the venters which was conducted for other grounds. Approximately 75 % of abdominal aortal aneurisms are symptomless and are found by the way during abdominal physical scrutiny or radiographic probes ordered for other conditions, ( Anderson et al 2001 ) . Aneurysm tactual exploration on physical scrutiny has merely been shown to be sensitive in thin patients and those with abdominal aortal aneurism A ; gt ; 5 centimeter with an overall sensitiveness and specificity of 68 % and 75 % , severally for sensing of AAA, ( Fink et al 2000 ) . The primary mode used to corroborate Mr X ‘s aneurysm size was made by ultrasound. Ultrasound is a standard image mode for an probe of suspected symptomless and surveillance of abdominal aortal aneurism. Ultrasound is safe, non-invasive, comparatively cheap, widely available and does non expose patient to radiation. You read "Abdominal Aortic Aneurysm Health And Social Care Essay" in category "Essay examples" It is the best option for observing and mensurating the size of aneurism. However, harmonizing to Sparks et Al ( 2002 ) ultrasound can non accurately specify the extent of the aneurism as it can be altered by intestine gasses, and hence is unequal for preoperative planning of endovascular fix. Computerized Tomography Angiogram ( CTA ) of the venters was the 2nd mode to be used to look into the extent of Mr X ‘s abdominal aortal aneurism and the aneurysmal cervix for preoperative planning. CTA is going the diagnostic imagination mode of pick in the preoperative appraisal of patients with an abdominal aortal aneurism. However it has some disadvantages for case, it uses high doses of radiation, cost effectual and requires endovenous contrast but it is faster and extremely accurate in finding the size and extent of the aneurism, and its relation to the nephritic arterias. ( Hafez 2009 ) . The other mode that could hold been used for preoperative planning for Mr X ‘s abdominal aortal aneurism is magnetic resonance angiogram ( MRA ) . Harmonizing to Aburahma ( 2007 ) , MRA is merely used for surgical planning fix when CTA contradicts with patients with contrast allergic and nephritic failure. However, both computerized imaging and magnetic resonance imagination are effectual for preoperative planning fix. CTA and MRA imaging provide high-resolution imagination of the aorta and find proximal and distal boundaries of the aneurism, says ( Upchurch 2009 ) . MRI scan is comparatively clip devouring, really expensive and may be distorted by gesture artifact, extended calcified plaque and metallic surgical stents Upchurch ( 2009 ) . Hence, MRA is non used for preoperative appraisal of endovascular fix. Mr X ‘s preoperative mode was good as he did non hold any contraindication such as contrast allergic reaction or nephritic failure for him to undergo a magnetic resonance angiogram scan. With magnetic Resonance Angiogram, endovenous dye is non required and it does non expose the patient to radiation as compared to Computer Tomography Angiogram, ( Truijers 2009 ) The primary end of intervention depends on the size of the aneurism, the possibility of rupture and the patient ‘s status. The purpose of surgical intervention is to forestall aneurism from rupture for patients with symptoms such as back hurting, or symptomless aneurism greater than 5.5 centimeter in diameter, ( Hakaim 2006 ) . When sing intervention of abdominal aortal aneurism there are two types of fix ; unfastened fix and endovascular aneurism fix. Endovascular aortal fix ( EVAR ) was recommended as the most appropriate intervention for Mr X taking into history short and long term hazards and the benefits of both processs in relation to his age and co-morbidity every bit good as anatomical suitableness. This Endovascular aortal fix is a safe process and can be efficaciously performed in a patient with the suited anatomy for illustration, a individual with infrarenal aortal diameter no larger than 26 millimeters and aortal cervix length at least 15-20mm without inordinate angulations, ( Hallett 2009 ) . However, in such patients with a suited anatomy and surgical expertness, increasing the usage of endovascular aortal fix is likely justified based on its better preoperative result informations ( Hallett 2009 ) . EVAR relies to a great extent on nomadic C-arm image intensive. This enables the sawbones to utilize x-ray images to visualize the interpolation of stent transplant through the femoral arteria up to the site of the aneurism while being imaged. However, this it exposes patient to radiation during the process and in subsequent follow up EVAR is a less invasive process with a potentially reduced morbidity, mortality of 1.6 % , intensive attention, entire infirmary stay and a rapid recovery clip comparison to open fix with morality of 4.6 % , ( Tinkham 2009 ) . In the prospective randomized controlled tests, EVAR has been shown to hold a signifi ­cantly better preoperative result, ( Tinkham 2009 ) . In contrast to EVAR, unfastened fix requires a surgical exposure of the aorta clamping. Open fix was non recommended for Mr X because of hapless province of wellness due to his medical co-morbidities which limit his day-to-day activities. Harmonizing to Anderson ( 2009 ) , unfastened fix is non suited for patients with co-morbidity including terrible chronic clogging pneumonic disease or myocardial misdemeanor which places at high hazard. EVAR carries a higher hazard of complications which would necessitate farther surgery to rectify. This requires postoperative long-run follow-up imagination as the long term lastingness of the stent transplant remains unsure, ( Liaw et al 2009 ) . Mr X underwent a postoperative follow up obviously abdominal x beam and ultrasound at 1 month to look into the stent transplant unity and migration. Plain skiagraphy is easy to obtain and widely available. It still plays a utile function in measuring the metallic unity of the stent transplant but the truth of endoleaks is limited. However, the field movie can be used in concurrence with ultrasound as a method of follow up, ( Mattes et al 2011 ; Ginter et al 2009 ) . Duplex ultrasound imaging is non-invasive compared to CT. Studies show that duplex ultrasound had a sensitiveness of 90 % while CT had of 58 % in sensings of endoleaks, ( Badri et al 2010 ) Contrast-enhanced CT is another imaging mode that could hold been used for Mr X ‘s postoperative endovascular aortal fix. This image mode is expensive, less accurate in sensing of little endoleaks and it exposes patients to radiation and is. However, the major concern sing the frequent usage of contrast-enhance CT including additions cost and cumulative radiation doses which leads to lifetime malignant neoplastic disease hazard to patients have shift toward color semidetached house ultrasound, ( Mattes et al 2011 ) . MRA is alternate mode could hold been used for postoperative rating of Mr X ‘s stent transplant fix. Mr X can non undergo MRA as his aneurism was treated with Zenith stent transplant which may be distorted by gesture artifact in the magnetic field. Harmonizing to Liaw et Al ( 2009 ) , MRA is every bit accurate as CTA for sensing of endoleaks but is really expensive and can non be usage to image ferromagnetic stent transplants such as Zenith. Hence, MRA is non utile for postoperative rating of patients with stent transplants Decision I think the tract taken to name Mr X ‘s abdominal aortal aneurism was right and besides the most current pattern taken in many infirmaries. Endovascular aortal fix is a less invasive process with a potentially decreased morbidity and mortality. Endovascular aortal fix has been widely performed and it is an effectual option to open fix, peculiarly for patients with medical comorbidities. However, the mandatary follow up after is a disadvantage of this technique. Despite the disadvantages, CT remains the most widely used mode in preoperative planning for abdominal aortal aneurism and postoperative surveillance after endovascular aortal fix. In contrast to computing machine imaging, ultrasound is the simplest, cheapest, mode used for suspected and surveillance of AAA. It is a standard mode used in concurrence with field movie in some infirmaries for follow up after endovascular aortal fix. Overall, imaging provides an spread outing aggregation of tools, leting progressively accurate probe of AAAs and patient choice for endovascular aortal fix. Surgeons and radiotherapists in this field should be cognizant of the technological betterments in each imagination mode, to do the right picks before, during and after endovascular aortal fix How to cite Abdominal Aortic Aneurysm Health And Social Care Essay, Essay examples

Global Warming1 Essay Example For Students

Global Warming1 Essay Now, for the first time in Earths history, humans may be a decisive factor in future climate change. The actions we make towards the temperature of the earth and the depletion of the ozone layer are irreversible. A warmer future could result from present-day human activities releasing large amounts of heat-trapping gases into the air. These greenhouse gases are part of the reason for the 1F (.5C) rise in global average temperature documented over the past 100 years. If the Earths temperature continues to rise as predicted, future global warming could happen faster than any climate change of the last 10,000 years. If so, future variations in local climate could be even more disruptive than those of the past. Fossil fuels, which release carbon dioxide when burned, are used to generate electricity; heat and light homes and workplaces; power factories and run cars. Unless we reduce population growth and use of fossil fuels, the level of carbon dioxide in the atmosphere will double by som etime in the middle of the next century. The future of Earths climate may depend partly on the buildup of heat-trapping gases, primarily carbon dioxide, methane, and nitrous oxide, in the atmosphere. Industrialized nations now release the most carbon dioxide. But how can this world wide disaster be stopped? To fully understand the magnitude of this problem, we must look at the causes of global warming, what is being done to stop the problem, consequences of this issue, and how we can prevent it. The depletion of the ozone layer and global warming are a result of the heat trapping abilities of greenhouse gases. The glass panels of a greenhouse and the Earths atmosphere are both transparent to sunlight, and both trap heat. Energy from the sun drives the earths weather and climate, and heats the earths surface; in turn, the earth radiates energy back into space. Atmospheric greenhouse gases trap some of the outgoing energy, retaining heat somewhat like the glass panels of a greenhouse. Thus creating the greenhouse effect. At present, the Earth appears to be facing a rapid warming, which most scientists believe results, at least in part, from human activities. The chief cause of this warming is thought to be the burning of fossil fuels, such as coal, oil, and natural gas, which releases into the atmosphere carbon dioxide and other substances known as greenhouse gases. As the atmosphere becomes richer in these gases, it becomes a better insulator, retaining more of the heat provi ded to the planet by the Sun. Through years of abuse and neglect, the situation continues to worsen. Some may feel that Global warming is inevitable, and that the climate will change no matter what. This is partly true. Climate does change all the time, but it changes slowly. We are doing it at enormous speeds, 60 times faster than normal. All life on Earth relies on the greenhouse effect, without it, the planet would be colder by about 33-Celsius degrees, and ice would cover Earth from pole to pole. However, a growing excess of greenhouse gases in Earths atmosphere threatens to head in the other direction, toward continual warming. Carbon dioxide is the most abundant greenhouse gas followed by methane and nitrous oxide. Carbon dioxide flows into the atmosphere from many natural processes, such as volcanic eruptions; the respiration of animals, which breathe in oxygen and exhale carbon dioxide; and the burning or decay of organic matter, such as plants. Humans escalate the amount of carbon dioxide released to the atmosphere when they burn fossil fuels, solid wastes, and wood products to heat buildings, drive vehicles, and generate electricity. At the same time, the number of trees available to absorb carbon dioxide through photosynthesis has been greatly reduced by deforestation, the long-term destruction of forests by indiscriminate cutting of trees for lumber or to clear land for agricultural activities. Methane is an even more effective insulator, trapping over 21 times more heat than does the same amount of carbon dioxide. Methane is emitted during the production and transport of coal, natural gas, and oil. Methane also comes from rotting organic waste in landfills, and it is released from certain animals, especially cows, as a byproduct of digestion. Nitrous oxide is a powerful insulating gas released primarily by burning fossil fuels and by plowing farm soils. Nitrous oxide traps over 270 times more heat than does the same amount of carbon dioxide. Since the beginning of the industrial revolution, atmospheric concentrations of carbon dioxide have increased nearly 30%, methane concentrations have more than doubled, and nitrous oxide concentrations have risen by about 15%. These increases have enhanced the heat-trapping capability of the earths atmosphereThis chart shows how much warming coul d be caused by each of the gases that human activities release. Carbon dioxide accounts for three fourths of the predicted increase in the greenhouse effect. Essay on The Dangers of Fracking EssaySome critics find the Kyoto Protocol too weak. Even if it were enforced immediately, it would only slightly slow the buildup of greenhouse gases in the atmosphere. Much stronger action would be required later, particularly because the developing nations exempted from the Kyoto rules are expected to produce half the worlds greenhouse gases by 2035. The most influential opponents of the protocol, however, find it too strong. Opposition to the treaty in the United States is spurred by the oil industry, the coal industry, and other enterprises that manufacture or depend on fossil fuels. These opponents claim that the economic costs to carry out the Kyoto Protocol could be as much as $300 billion, due mainly to higher energy prices. Proponents of the Kyoto sanctions believe the costs will prove more modest $88 billion or less much of which will be recovered as Americans save money after switching to more efficient appliances, vehicles, and industrial processes. We are all generally guilty of contributing to the effects of Global Warming: In the United States, approximately 6.6 tons (almost 15,000 pounds) of green house gases are emitted per person every year. And emissions per person have increased about 3.4% between 1990 and 1997. Most of these emissions, about 82%, are from burning fossil fuels to generate electricity and power our cars. However there are many things you yourself can do to reduce the emissions of fossil fuels, and in turn prevent global warming. For example, things as simple as: car pooling, keeping your vehicle well-maintained, using energy efficient appliances, etc Also investing in a new hybrid vehicle is without a doubt a smart decision for the environment.
