The Study of Punishment in Psychology
The Study of Punishment in Psychology Theories Behavioral Psychology Print The Study of Punishment in Psychology By Kendra Cherry facebook twitter Kendra Cherry, MS, is an author, educational consultant, and speaker focused on helping students learn about psychology. Learn about our editorial policy Kendra Cherry Updated on January 15, 2020 Blend Images / Getty Images More in Theories Behavioral Psychology Cognitive Psychology Developmental Psychology Personality Psychology Social Psychology Biological Psychology Psychosocial Psychology Punishment is a term used in operant conditioning to refer to any change that occurs after a behavior that reduces the likelihood that that behavior will occur again in the future. While positive and negative reinforcement s are used to increase behaviors, punishment is focused on reducing or eliminating unwanted behaviors. Punishment is often mistakenly confused with negative reinforcement. Remember, reinforcement always increases the chances that a behavior will occur and punishment always decreases the chances that a behavior will occur. Types of Punishment Behaviorist B. F. Skinner, the psychologist who first described operant conditioning, identified two different kinds of aversive stimuli that can be used as punishment. Positive Punishment: This type of punishment is also known as punishment by application. Positive punishment involves presenting an aversive stimulus after a behavior has occurred. For example, when a student talks out of turn in the middle of class, the teacher might scold the child for interrupting her.??Negative Punishment: This type of punishment is also known as punishment by removal. Negative punishment involves taking away a desirable stimulus after a behavior has occurred. For example, when the student from the previous example talks out of turn again, the teacher promptly tells the child that he will have to miss recess because of his behavior. Is Punishment Effective? While punishment can be effective in some cases, you can probably think of a few examples of when a punishment does not reduce a behavior. Prison is one example. After being sent to jail for a crime, people often continue committing crimes once they are released from prison. Why is it that punishment seems to work in some instances, but not in others? Researchers have found a number of factors that contribute to how effective punishment is in different situations. First, punishment is more likely to lead to a reduction in behavior if it immediately follows the behavior. Prison sentences often occur long after the crime has been committed, which may help explain why sending people to jail does not always lead to a reduction in criminal behavior. Second, punishment achieves greater results when it is consistently applied. It can be difficult to administer a punishment every single time a behavior occurs. For example, people often continue to drive over the speed limit even after receiving a speeding ticket. Why? Because the behavior is inconsistently punished. Drawbacks and Consequences of Punishment Punishment also has some notable drawbacks. First, any behavior changes that result from punishment are often temporary. Punished behavior is likely to reappear after the punitive consequences are withdrawn, Skinner explained in his book About Behaviorism. Perhaps the greatest drawback is the fact that punishment does not actually offer any information about more appropriate or desired behaviors. While subjects might be learning to not perform certain actions, they are not really learning anything about what they should be doing. Another thing to consider about punishment is that it can have unintended and undesirable consequences. For example, while approximately 75 percent of parents in the United States report spanking their children on occasion, researchers have found that this type of physical punishment may lead to antisocial behavior, aggression, and delinquency among children. For this reason, Skinner and other psychologists suggest that any potential short-term gains from using punishment as a behavior modification tool need to be weighed again the potential long-term consequences.

Running head: RACIAL PROFILING Racial Profiling: Are we Fighting it the Right Way? Racial Profiling: Are we Fighting it the Right Way? I would like to talk about an issue that is plaguing our community today and making the job of a Police Officer even more difficult than it already is. All for one reason, statistics!! Racial profiling to me is a lot like any other problem in our society today. Many have different opinions on why it happens, and what we should do about it if it does happen. The problem is nobody can come to a consensus on how to solve this problem. It seems to me that racism is still part of our society, and sadly, I think it always will be. We all have prejudices of some sort towards others. It may be because ofâ⬠¦show more contentâ⬠¦Police Chiefs and Police Officers country wide think that is inherently unfair. A good example of this is if a police officer is assigned to a neighborhood with large numbers of minorities he/she will inevitably write more tickets to the minority population than other officers assigned to predominantly white neighborhoods. In turn officers in minority neighborho ods would be branded unfairly. These officers would protect themselves and not write as many tickets. The minority neighborhoods would then not get the same level of police protection as others. I have seen this also happening with the profiling forms that officers complete for after each traffic stop. Police officers are picking and choosing their traffic stops more often to keep their numbers even. This is hurting police work more than it is helping to solve the problem of racial profiling. (www.seattlep-i.com, Thorny Racial Profiling Debate, Feb. 2002) I went to the other side of the debate and read what the ACLU and NAACP had to say about racial profiling.

Probability plays a crucial and important role in many things: industries, recreation, etc. Letââ¬â¢s see how many we can think of. I know that we will all be amazed at how much our every day life is influenced by probability. We will write a custom essay sample on Make Probability Real or any similar topic only for you Order Now â⬠¢ Identify at least one example of probability encountered in everyday life which has not previously been mentioned. I am the ââ¬Å"chefâ⬠in the house and work most of my hours in the afternoon. As I am the one who is the most creative in the kitchen and the evening hours at work prevents me form cooking dinner during a normal time, the probability of me cooking and having dinner prepared before noon, to be heated up later is very high. If my family is to eat a home cooked meal, I am the one to create it. The probability is between 95-97%. â⬠¢ â⬠¢ Explain how probability is used in that situation. Probability is used in the above situation because nobody in my home can cook a homemade meal. They love to eat, but they are terrible in the kitchen. The only way that they will eat a home cooked meal in our home is if I cook it earlier in the day and they re-heat it at dinner time. If something had come up during the day, and I am unable to cook a meal, then the probability that anyone in the house would cook would be zero; because as I stated earlier I am the only cook in our home. â⬠¢ â⬠¢ Identify the type of probability your example best fits by explaining whether it is an independent event or dependent upon something else. This situation described could be either a dependent or independent event. In the case of a dependent event, I would be available during the day, with all of the ingredients to prepare the meal and nothing comes up during the day that would preclude me from cooking the meal. In the event that something came up, this would become an independent event because then I would not be available to cook because I was not at the house able to cook. The greater probability of me being available early in the day is greater than me not being available to cook; because without me cooking my family would have to go out to eat and we are a family who loves to have a different home made creation daily.

Mononucleosis 2 Essay Example For Students
Mononucleosis 2 Essay Mononucleosis is a disease caused by the Epstein-Barr virus (EBV), which is a member of the herpes family. The herpes family also includes viruses that cause cold sores, chicken pox, genital herpes, and birth defects (7). Mono, short for mononucleosis (3) gets its name from the fact that it causes a persons white blood cells to become distorted, so that they have only one nucleus (becoming mononuclear) instead of the usual divided nucleus.; (3)The first accounts of mono are credited to Filatov and Pfeiffer who around the end of the nineteenth century described and illness known as Drusenfieber or glandular fever which occurred in family outbreaks. However, the establishment of mono is given to Sprunt and Evans. In 1921 they pointed out the mononuclear lymphocytosis that was present in each patient they treated. Two years later, Downey and McKinaly provided more details of the lymphocytes as a marker that led to the disease. (6)The idea of EBV being connected to mono came about in 195 8 by Burkitt. There were some cases in Africa of young children having tumors in their jaw and dying even when the tumor was removed. He later found out that the patients were coming from areas highly infested with mosquitoes, so they figured that the mosquitoes were related. The mosquitoes were carrying a virus in the herpes family, which was later called Epstein-Barr virus. This virus was later revealed to be linked with mono. (6)Anyone can get mono but it is most common in teens and young adults, mostly high school and college students. Children who are infected with EBV when they are really young are able to manufacture antibodies against the virus. If a persons body does not have EBV already they will most likely contract the virus later in their life and be able to build these antibodies. Only a small amount of teens and young adults actually get mono because they have already been exposed to EBV at a younger age. (7)Mono usually occurs in females between the ages of 15 to 16 years, and males between the ages of 18 to 23 years (4). People call it the kissing disease; due to the fact that it is spread through close contact and saliva (2). Drinking after someone, or eating after him or her can also contract mono (2). In the United States more than 100,000 cases of mono are diagnosed each year (7). At colleges 300 to 1500 out of 100,000 people get mono (7). Mono affects mainly the lymphatic system (7). The lymph system carries foreign invaders like EBV to special tissues where disease-fighting white blood cells called lymphocytes spring into action.; (7) However EBV only infects the B cells that produce antibodies. During mono one out of every ten B cells becomes atypical.; The T cells in the body then go find the B cells infected and that is what makes the body feel fatigued and sick is when it is fighting its own cells. The lymph nodes where the body is attacking itself, such as the tonsils become inflamed, causing symptoms such as a sore throat. Eventual ly the T cells have done their job and the body is back under control, but there are still infected cells causing mono to relapse and take a long time to recover from. However, it is very unusually for mono to occur more than once in a persons lifetime. (7)The symptoms for mono include sore throat, fever, headache, loss of appetite, extreme fatigue, sometimes a measles-like rash, jaundice, or the spleen may enlarge and there is the possibility of a rupture. These symptoms are very common for other disease such as the common cold or strep throat. Blood tests are the only way to find out if someone is infected with mono due to the abnormal white blood cells. (2)Although there is no specific treatment or medicine for mono the best thing is to just rest (3). Drinking plenty of fluids helps also (3). You can take pain relievers such as acetaminophen, which is Tylenol and others like it, but never take aspirin (3). Taking aspirin while having a viral infection can lead to another serious condition called Reyes syndrome (3). While having mono, a person should limit their activities such as sports and exercises (7). The Illness can last from two weeks and in the severe cases, months (1). There is no sure way to prevent mono because it is so highly contagious and there are no vaccines for it. Obviously a person should avoid contact with anyone who is infected with mono. A person with AIDS, and transplant recipients need to be extra careful because contracting EBV can lead to cancer. (7)EBV can lead to other Illnesses other than mono. Burkitts lymphoma patients usually have high antibodies of EBV (6). This disease involves tumors in the throat and jaw area due to EBV (6). There are also traces of EBV genome in specimens from nasopharyngeal carcinoma (6). Nasopharynegeal carcinoma is cancer of the nose and throat and EBV is found in almost all of the tumors (7). Hodgkins disease is possibly linked with EBV because of the swelling of lymph nodes in the neck, armpits, or g roin, and similar symptoms of mono (7). EBV could be linked with Sjogrens syndrome, which is a chronic autoimmune disease where the body attacks its own tissues (7). EBV could be involved because an EBV infection of the salivary glands activates the T cells to the infected cells and to other glandular cells (7). Although EBV is linked to many other diseases and could cause cancer, there is no evidence that everyone with EBV antibodies is going to get cancer or another deadly disease (7). .u3a4ccddfb3f6a03506b3586778978ed7 , .u3a4ccddfb3f6a03506b3586778978ed7 .postImageUrl , .u3a4ccddfb3f6a03506b3586778978ed7 .centered-text-area { min-height: 80px; position: relative; } .u3a4ccddfb3f6a03506b3586778978ed7 , .u3a4ccddfb3f6a03506b3586778978ed7:hover , .u3a4ccddfb3f6a03506b3586778978ed7:visited , .u3a4ccddfb3f6a03506b3586778978ed7:active { border:0!important; } .u3a4ccddfb3f6a03506b3586778978ed7 .clearfix:after { content: ""; display: table; clear: both; } .u3a4ccddfb3f6a03506b3586778978ed7 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u3a4ccddfb3f6a03506b3586778978ed7:active , .u3a4ccddfb3f6a03506b3586778978ed7:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u3a4ccddfb3f6a03506b3586778978ed7 .centered-text-area { width: 100%; position: relative ; } .u3a4ccddfb3f6a03506b3586778978ed7 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u3a4ccddfb3f6a03506b3586778978ed7 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u3a4ccddfb3f6a03506b3586778978ed7 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u3a4ccddfb3f6a03506b3586778978ed7:hover .ctaButton { background-color: #34495E!important; } .u3a4ccddfb3f6a03506b3586778978ed7 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u3a4ccddfb3f6a03506b3586778978ed7 .u3a4ccddfb3f6a03506b3586778978ed7-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u3a4ccddfb3f6a03506b3586778978ed7:after { content: ""; display: block; clear: both; } READ: Corporate Wellness Programs Essay Right now there is no vaccine for EBV or mono, but scientists are working on it (7).

Robert Frost Takes Our Imaginations To A Journey Through Wintertime Wi
Robert Frost takes our imaginations to a journey through wintertime with his two poems Desert Places and Stopping by Woods on a Snowy Evening. Frost comes from a New England background and these two poems reflect the beautiful scenery that is present in that part of the country. Even though these poems both have winter settings they contain very different tones. One has a feeling of depressing loneliness and the other a feeling of welcome solitude. They show how the same setting can have totally different impacts on a person depending on their mindset at the time. These poems are both made up of simple stanzas and diction but they are not simple poems. In the poem Desert Places the speaker is a man who is traveling through the countryside on a beautiful winter evening. He is completely surrounded with feelings of loneliness. The speaker views a snow covered field as a deserted place. A blanker whiteness of benighted snow/ With no expression, nothing to express. Whiteness and blanknes s are two key ideas in this poem. The white symbolizes open and empty spaces. The snow is a white blanket that covers up everything living. The blankness symbolizes the emptiness that the speaker feels. To him there is nothing else around except for the unfeeling snow and his lonely thoughts. The speaker in this poem is jealous of the woods. The woods around it have it - it is theirs. The woods symbolizes people and society. They have something that belongs to them, something to feel a part of. The woods has its place in nature and it is also a part of a bigger picture. The speaker is so alone inside that he feels that he is not a part of anything. Nature has a way of bringing all of her parts together to act as one. Even the animals are a part of this wintery scene. All animals are smothered in their lairs,/ I am too absent-spirited to count. The snow throws its blanket of whiteness over everything and to him it is a feeling of numbness. The loneliness includes me unawares. The spe aker has lost his enthusiasm for life. He can not express his feelings easily because of this feeling of numbness. The speaker is also in denial about feeling alone. He is at a stage where he just does not care about too much and he is feeling a bit paranoid. They cannot scare me with their empty space. He is saying who cares how I feel, I do not need anyone else. I have in me so much nearer home/ To scare myself with my own desert places. The speaker was starting to realize that he had shut himself off to the world. He recognized that this winter place was like his life. He had let depression and loneliness creep into his life and totally take over like the snow had crept up on the plain and silently covered it. If he continues to let these feelings run his life, eventually everything would be snuffed out much like the snow does to nature. Stopping by Woods on a Snowy Evening is a much happier and more upbeat poem than Desert Places. This poem is about stopping to enjoy life or as the cliche goes, stopping to smell the roses. But I have promises to keep,/ and miles to go before I sleep. The speaker in this poem was a very busy man who always had obligations to fulfill and places to go. A feeling of regret is present. The man would like to stay and enjoy this private nature scene longer but he knows that he has other things to do. Again, Frost gives us a beautiful nature scene but this time we enjoy welcome solitude. The woods are lovely, dark and deep. This poem expresses the joy of nature. The speaker seems concerned about what the rest of society would think about him just stopping in the middle of nowhere for no apparent reason. His horse represents society. My little horse must think it queer/ To stop without a farmhouse near. He admits that just stopping does seem odd. He is also somewhat concerned about the man

French and Spanish Influance essays
French and Spanish Influance essays The French and Spanish responded differently to the culture and economy of the Native Americans. Even though both countries traveled to the New World for riches, their ways of obtaining the riches could not have been more different. The Spanish decided to conquer and enslave the Indians. The French traded peacefully with the Indians and changed both the Indian culture and their own culture to gain confidence with the Indians. The type of Spaniard, which arrived on the New World before 1750, was either a monk or a conquistador. The job of the conquistadors was to capture Indian cities and then loot them of all their riches. After the capturing and looting of cities, the conquistadors would usually enslave all the surviving Indian people to earn money for the conquistador. The Spanish government did not mind this because they got one fifth of all the profits of these settlements known as The Royal Fifth. Because of the lack of Spanish women, the conquistadors intermarried with the Indians creating a new race called Mestizos. In Spain, being a Mestizo or having Native American blood in your veins was looked down upon. The social hierarchy consisted of pure blood Spanish being at the top and pure Native Americans being at the bottom. This created a natural block against any people with Native American blood holding a high position in Spain, which was probably one of the main reasons Indian slavery was never put into question by the Spaniards. The monks of Spain were no better then the conquistadors. The monks only goal was to convert the Native Americans to Catholicism. These servants of God destroyed the Indian temples and built churches where they once lay. No part of Indian culture was allowed to be retained by the Native Americans. The effect of this was the Indians did not accept Catholicism but they also lost ties to their own culture. The French had a more peaceful approach to the Indians. The f...

Chronic Kidney Disease: Pathology and Biochemistry
Chronic Kidney Disease: Pathology and Biochemistry The kidneys are a pair of organs that function to removing metabolic wastes like urea, carbon dioxide, salts, and chemicals from the blood and excreting these wastes as urine. Kidneys also regulate the concentration of body fluids and electrolyte concentrations, arterial pressure, secretion/excretion of hormones and acid-base balance of body fluids (Guyton Hall, 2005). The main functional filtering unit of the kidney is the nephron. At least 800 thousand nephrons are in one kidney. The initial filtering unit in the nephron is the glomerulus, and the filtrates coming from the glomerulus are formed into urine as it passes the other components in the nephron. Diseases in the kidney cause a significant number of deaths and disabilities worldwide (Coresh, et al., 2007). Acute renal failure is manifested by the kidneys abruptly stopping, although the chance exists that the kidneys could recover, while in chronic kidney disease there is a progressive decline in the function of the nephrons. More specifically, chronic kidney disease is defined as damaged or decreased kidney function measured by a decrease in the glomerular filtration rate (GFR) for a period or three or more months (Levey, et al., 2003). Initial damage to the nephron results in compensatory responses of the remaining nephrons allowing for the continuation of clearance of blood solutes. The compensatory action of the nephrons during early damage is thought to be a major cause of renal damage, because during compensation the glomerular capillary pressure is increased so much that damages are incurred leading to lesions in the glomeruli (Arora Verelli, 2010). Chronic kidney disea se is also caused by hypertension, diabetes, disorders in blood vessels and glomeruli, infections, immune system disorders, congenital disorders, and urinary tract obstructions (Guyton Hall, 2005). Clinical symptoms for chronic kidney disease are not evident until the number of functional nephrons decreases by 70-75% (Guyton Hall, 2005). The progressive deterioration in kidney function could ultimately lead to end-stage renal disease where the patient must undergo dialysis to remove wastes from the blood, or transplanted with a new kidney. Chronic kidney disease has 5 stages based on the GFR (National Kidney Foundation, 2002). Patients with the stage 1-3 of the disease do not show symptoms. At stage 4-5 electrolyte balance and endocrine disorders become evident. It is believed that the uremic disorders observed at stage 5 are due to the accumulation of toxins (Arora Verelli, 2010). Increased retention of potassium (hyperkalemia) occurs due to inability of the kidneys to excrete potassium. Metabolic acidosis results from the inability of the kidneys to produce enough ammonia necessary to react with the endogenous acid and produce ammonium. Phosphates, sulphates, and other organic anions accumulate, causing large anion gaps. Metabolic acidosis increases protein degradation and amino acid oxidation, and reduces albumin synthesis, resulting in protein-energy malnutrition, decreased body mass, and increased muscle weakness. Acidosis also interferes with Vitamin D metabolism and mineral imbalance resulting in renal osteodys trophy or renal bone disease. Renal bone disease can be averted with timely dietary measures and medications like phosphate binders and calcitriol (Renal Resource Center, 2007). Skeletal and extraskeletal complications result from the progression of renal bone disease. In chronic kidney disease, renal bone disease is categorized into four general types: (1) low turnover disease or defective mineralization; (2) high turnover bone disease brought about by high levels of the parathyroid hormone (PTH) levels; (3) beta-2-microglobulin associated bone disease; and (4) mixture of the 3 diseases (Arora Verelli, 2010). Diagnosis and management of chronic kidney disease Chronic kidney disease is diagnosed by laboratory tests on urine and serum. Serum creatinine as an estimate of glomerular filtration rate, albumin-creatinine ratio in the urine, and examination of urine sediment and dipstick test for erythrocytes and leukocytes are recommended (Levey, et al., 2003). Image analysis by ultrasound can be performed for patients with symptoms of stones, infection, obstruction of the urinary tract and having a family medical history of polycystic kidney disease. Serum electrolytes should be measured on patients who are hypertensive, diabetic, and those who have been exposed to drug toxicity. Other tests include urinary concentration or dilution, and acidification for selected patients who present symptoms of polyuria, metabolic acidosis, metabolic alkalosis, hypo- and hyperkalemia (very high levels of potassium). Kidney function is assessed by analyzing serum creatinine along with a blood urea nitrogen test (Lab Tests Online, 2009). Creatinine clearance is an indication of the efficiency of the kidneys in filtering small molecules out of the blood. A traditional and principal marker of kidney damage is persistent or recurring proteinuria (Kean Eknoyan, 1999). Proteins are large molecules, and therefore they cannot pass the membranes of the glomeruli into the urine. Glomeruli, being negatively charged, also repel proteins. Size and charge barriers do not allow the passage of proteins into urine, unless the glomeruli are damaged (Proteinuria and microalbuminuria, 2007). Proteins can be measured using reagent strip tests for point of care detection and laboratory tests, including immunoassays (Carter, Tomson, Stevens, Lamb, 2006). When the protein level is more than 3500 milligrams, extensive glomeruli damage has already occurred. An albumin (or protein)-creatinine ratio higher than 30 mg albumin/g creatinine, is abnormal since the cut-off points are greater than 17 mg/g in males and more than 25 mg/g in females (Warram, Gearin, Laffel, Krolewski, 1996; (Jacobs, Murtaugh, Steffes, Yu, Roseman, Goetz, 2002). Glomerular filtration rate (GFR) is currently the best test for detecting kidney disorders. GFR is estimated using a formula that uses serum creatinine value, and gender, age and weight of individual. The GFR has been recommended to be the main criterion in classifying kidney disease. Five stages of chronic kidney diseases have been identified based on the glomerular filtration rate (GFR) (National Kidney Foundation, 2002). Kidney damage has been proposed with normal or increased GFR of > 90 mL/min per 1.73 m2, while kidneys have already failed when the GFR greatly decreased at Indications of chronic kidney disease are varied and diverse. Increase or decrease in levels of important electrolytes phosphate, potassium and calcium. Other indications are metabolic acidosis, pericarditis, malnutrition, neuropathies and cardiovascular complications (Shlipak, et al., 2005; Tonelli, et al., 2006). The treatment of chronic kidney disease depends on the stage of the disease and should focus on several important factors (Arora Verelli, 2010). The primary objective is to delay and halt the progression of the disease by treating the known underlying condition (e.g. hypertension, diabetes). Systolic blood pressure, hyperlipidemia, and glycemic levels must be controlled, and use of angiotensin receptor blockers is recommended. Pathologic symptoms should be treated as follows: anemia with erythropoietin; high phosphate levels with dietary means for binding and restricting phosphate binders; low calcium levels with supplements and hyperparathyroidism with vitamin D analogs or calcitriol (Arora Verelli, 2010). For uremic manifestations, dialysis and transplantation are recommended depending on the stage of the diseases, and the indications. Timely planning for renal transplantation is also necessary in order to prepare the patient. Reflection on module Chronic kidney disease is prevalent worldwide, with millions of people affected. The review conducted here shows that the disease has been well characterized with respect to the point-of- care and clinical tests for diagnosis. Chronic kidney disease affects the accumulation of ions in the blood therefore leading to a multitude of adverse conditions. The US National Kidney Foundation has spearheaded efforts to standardize and systematize the different stages, diagnostic approaches and treatment modalities. Apparently, chronic kidney disease results from other disorders. Therefore it can be prevented and corrected by first preventing and curing the underlying cause. This makes the nature of the disease complicated, and solutions are also complex. What is clear is that kidney disease is mostly a result of lifestyle, since most underlying causes like diabetes, cardiovascular disease, and hyperlipidemia are mostly due to lifestyles. A limitation in the publications that were reviewed was the lack of clear recommendations on how the onset of chronic kidney disease can be prevented, and what specific medications can lead to repair of the glomeruli and the nephrons after damage has occurred. Clearly, a patient with chronic kidney disease is saddled with the knowledge that a complete cure is not possible; and it only takes a matter of time for one to have the end-stage renal disease. The challenge for the medical community is to come up with a clear preventive strategy against kidney disease, and to have other long-term options aside from dialysis or organ transplantation.

Disc Arthroplasty Essay
Degenerative disc disease have been a problem for many people as this disease brings about low back pain that seems to paralyze the working force, à the middle adulthood population (Smeltzer, 2004). Not only does it bring impaired quality of life to those who suffer from it, but Arvind Kulkarni adds large health care expenses to the list of problems brought about by this disease as seen in his article entitled Prosthetic Lumbar disc replacement for degenerative disc disease. Spinal fusion, which is the medical management for degenerative disc disease, has been criticized by several doctors in the practice due to its untoward effects in the patientââ¬â¢s overall recovery and lifetime improvement. Specialist in the field, Christoph Siepe, identified these unpleasant effects as accelerated adjacent system degeneration, pseudarthrosis, spinal canal stenosis, and donor site morbidity. Adjacent segment degeneration, as mentioned by Peter Ullrich in his article entitled Fusion versus Artificial Disc Arthroplasty for Lumbar Degenerative Disc Disease, stated that this is the major complication of spinal fusion and the reason why most surgeons want this procedure replaced. Adjacent segment degeneration or ASD happens when mechanical stress is transferred to the adjacent segment, also mentioned by Peter Ullrich. But research showed that this procedure can be modified to show more positive results. An anterior lumbar interbody fusion showed a low occurrence of revision surgery needed, which meant low frequency of adjacent segment degeneration, all pointed out in Mr. Ullrichââ¬â¢s paper.à However, to achieve this outcome, Mr. Ullrich declared that there should be an improvement in patient selection and in the procedure. The patients should be those patients having degenerative disc disease in their 5th lumbar to 1st sacral segment, because there is minimal motion at this level. By doing so, he states that fusing these segments do not change the patientââ¬â¢s mobility as much. à But not all are satisfied of this result. Doctors and specialists are continuously making efforts to totally changing the primary medical management for degenerative disc diseases. Studies have been conducted, and several replacement procedures were approved by the FDA. Peter Ullrich stated in his paper that the total disk replacement procedure was approved for medical use by the FDA in the year 2004 using the Charite artificial disc but for only one level of the spinal vertebrae, being the L4 ââ¬â L5 or the L5 ââ¬â S1. This is not the first time that a total or partial disc replacement was done. The history of this procedure was mentioned in an article in a website by Spine-Health that disc nucleus replacement was done first in 1955 by David Cleveland by injecting methyl-acrylic. Ever since then, there have two other FDA approved products aside from the Charite, the website Spine-Health states that the Prodisc was approved on August 2006 and the Kineflex lumbar on June 2005. à à à à à à à à à à à A total disc replacement is being described by Jose Reyna in his article, Advances in Artificial Disc Technology, as being composed of two pieces of plates made of metal that has teeth to be able to attach itself to the end plates of the vertebral bones above and below it. This means that the particular intervertebral disc that is causing pain has to be removed and replaced by an artificial disc. Several artificial discs have been developed by various manufacturers in the country and they only differ in design and composition. The Charite, as mentioned earlier, is made up of a unique sliding core with two metal alloy end plates. The Prodisc being based on spherical articulations is made up of cobalt chromium molybdenum alloy as stated in the website Spine-Health. Inventors Qi-Bin Bao and Paul Higham developed a hydrogel prosthetic nucleus made up of PVA powder and a solvent mixed together, as seen on the article, Hydrogel intervertebral disc nucleus with diminished lateral bulging. The total disc replacement procedure has its advantages and disadvantages. Even after some models being approved by the FDA, it is still being assessed thoroughly by specialists in the field. Charles Rosen and Douglas Kiester report poor results and complications in the total disc replacement procedure. As it was mentioned in their study, this procedure causes fractures, severe pain, dislocations, extrusion of the implant, facet joint degeneration, and unexplained radiculopathy. They attribute these substandard results to the fact that the center of rotation of segmented motion is erroneous. Jose Reyna Jr. also mentions several disadvantages of the procedure in his study, stating that the anterior approach to the surgery can cause injury to the aorta and the common iliac vessels, can cause retrograde ejaculation in men by injuring the superior hypogastric plexus, hemorrhage can result from the retroperitoneal approach, and infection can occur. However, he also stated some advantages, as this procedure is said to maintain range of motion in majority of the patients as a long-term outcome. There are still a lot of studies to be conducted, and patients to be experimented on. A three year study conducted by Christoph Siepe et al., entitled Clinical Results of Total Lumbar Disc Replacement With ProDisc II: Three-Year Results for Different Indications, intended to assess total disc replacement outcome in patients who actually underwent the operation. Their results showed that not all degenerative disc diseases can be treated with this medical management. The best outcome was seen in patients exhibiting degenerative disc disease condition plus soft disc herniation or nucleus pulposus prolapse. Outcome was measured against the patientââ¬â¢s improvement from their preoperative levels. There were inferior results from the patients who had bisegmental damages, and a higher complication rate. Also it was mentioned that the younger patients, more specifically those aged below forty exhibited better outcome than those older than forty. Technology like this is still being developed, studied and modified as we speak. What is important is that there are people out there who care and who try to make a difference, whether it is by inventing, criticizing or being the experimental person wherein these new devices will be made a reality.

Crystal Science Fair Project Tips and Ideas
Crystals can make interesting and fun science fair projects. The type of project depends on your educational level. Here are some examples of crystal science fair projects and ideas to help launch your own creativity in choosing your own project. Make a Collection Younger investigators may want to make a collection of crystals and work out their own method for grouping the crystals into categories.à Common crystals include salt, sugar, snowflakes, and quartz. What other crystals can you find? What are the similarities and differences between these crystals? What materials look like crystals, but really arent? (Hint: Glass doesnt have an ordered internal structure, so it isnt crystal.) Make a Model You can build models of crystal lattices. You can show how lattice subunits can grow into some of the crystal shapes taken by natural minerals. Prevent Crystal Growth Your project can involve ways you might prevent crystals from forming. For example, can you think of a way to keep crystals from forming in ice cream? Does the temperature of the ice cream matter? What happens as a result of freezing and thawing cycles? What effect do different ingredients have on the size and number of crystals that form? Grow Crystals Growing crystals is a fun way to explore your interest in chemistry and geology. In addition to growing crystals from kits, there are lots of types of crystals that can be grown from common household substances, such as sugar (sucrose), salt (sodium chloride), Epsom salts, borax, and alum. Sometimes its interesting to mix different materials to see what types of crystals result. For example, salt crystals look different when they are grown with vinegar. Can you figure out why? If you want a good science fair project, it would be better if you tested some aspect of growing crystals rather than simply growing pretty crystals and explaining the process. Here are some ideas for ways to turn a fun project into a great science fair or research project: How does the rate of evaporation of the crystal-growing medium affect the final size of the crystals? You can change the rate of evaporation by sealing the container (no evaporation at all if there is no air space) or by blowing a fan over the liquid or enclosing the jar of medium with a desiccant. Different places and seasons will have different humidities. The crystals grown in a desert may be different from those grown in a ââ¬â¹rainforest.You will usually heat water or another liquid to dissolve a solid to grow your crystals. Does the rate at which this liquid is cooled affect the way the crystals grow? You can compare crystals allowed to cool at room temperature to those formed from cooling the liquid in a refrigerator.What effect do additives have on the crystals? You could add food coloring, flavorings, or other impurities. How do crystals grown from non-iodized salt compare with those grown from iodized salt?What steps can you take to maximize crystal size? Developing a pr ocedure is a form of experimental science. You can affect parameters such as vibration, humidity, temperature, the rate of evaporation, purity of your growth medium, and time allowed for crystal growth. The type of container used to grow your crystals may make a difference, as could the type of string used to suspend a seed crystal (or other method used to grow a crystal). Are you changing containers when crystals start to grow that could compete with your seed crystal? There are lots of things to think about! Some may have a major effect on crystal growth and others may be negligible. Does light/dark effect growth? Probably not for a salt crystal, but it could for a substance that is degraded by visible radiation.If you are up for a challenge, you can make predictions about the shapes of crystals before you grow them, based on their molecular structures and molecular geometry.
