Business & its Environment (2 questions) 1. Describe Ikea's strategy Essay

Business and its Environment (2 inquiries) 1. Portray Ikea's system 2.Evaluate Ikea's market section stategy in North America - Essay Example (Brosi, Gabel, Buitt, and Stults, 2006) Kamprad's unassuming beginnings (he was the child of a rancher) had made a novel IKEA culture that was established on regard for cash and an inventive attitude (BII, 2006). Kamprad himself utilized his money related resources economically for even business purposes. His sensible mentality streamed down to the associates, who might guarantee insignificant wastage and cost cutting at each level and accordingly, IKEA concocted items that were tastefully planned were as yet accessible at reasonable costs (BII, 2006). IKEA has consistently made very much structured and utilitarian home items for individuals at low limited costs. However this isn't the main motivation behind why individuals need to purchase items from IKEA. Organization's meaning of Corporate Social Responsibility is extremely solid and it is worked in each store the world over. They advance condition benevolent items and supplies, have a green vehicle plan and utilize squander to-vitality innovation. IKEA's 'IWAY' for least prerequisites for social, working, and natural conditions point to the way that green business is in reality brilliant business. (Webb, 2007) (Brosi, Gabel, Buitt, and Stults, 2006) IKEA has done well to manufacture vital coalitions and establishments for extension purposes.

Problem Based Learning in Engineering Free-Samples for Students

Question: Looks at the connection between test nervousness in University Students and their Performance in Examinations. Answer: Instructive Institutes have been giving training to understudies from long time now. It is close to difficult to find the first of them. Notwithstanding, the manner in which educating has seen significant changes sometimes. Prior, the emphasis was on getting the understudies robbed up with all the hypothesis. Afterward, the useful situations appeared. The talk began to have a few models from genuine world. The opportunity has arrived when the method of talk based instructing is getting redone into more student driven methodologies. These are believed to give a greater number of experiences to understudies than the customary; techniques. The educators are additionally underlining on the equivalent. The down to earth critical thinking approaches are currently observed as the standard method of educating in the majority of the rumored organizations. These assistance the understudy to pick up information which they can really use in reality. The hypothetical information is less helpful w ith regards to true situations (Hung, 2008). Issue Based Learning (PBL) Issue Based Learning is a technique wherein the understudies themselves make objectives and learn by attempting to accomplish them by settling the current issues. They learn through their own encounters. The man thought behind PBL isn't to accomplish a specific objective yet to instill the aptitudes in the student by method of causing them to accomplish the objectives. The methodology helps in act of spontaneity of relational abilities of the student a ton. The more slender can feel the distinction after he/she goes to a specific meeting and afterward take a shot at his/her own. More often than not, the PBL helps in prepping the student to work in a Team Environment which is considerably more basic in todays quick paced life. Wood (2003) thinks about the PBL as a procedure which utilize the known issues inside a model which helps in the improvement of comprehension and information. According to him, the procedure is a constant one and starts with the self-distinguishing proof of objectives by the students. Understudies will perform autonomous examinations and afterward present themselves in a gathering where they can talk about the points. These assistance the understudies to learn in a PBL way and they additionally figure out how to function in a group. The gathering size need not be huge. It very well may be a little gathering of 9-10 individuals. The individuals from the gathering have their individual tasks to carry out inside the gathering. Issue Based Learning is an extraordinary path for students to feature their ability before a gathering at an early age. Numerous individuals face issues in their prime time working in a group domain (Lundeberg, 2009). In this manner, PBL from beginning of instruct ive profession is useful for the students. Issue Based Learning in Engineering Education PBL was first begun in Medical stream yet now it has seen wide acknowledgment in a wide range of streams. The PBL encourages the student to create abilities which they will rehearse in future to comprehend life issues. It helps students picking any vocation. The understudies in an Engineering Institute can be solicited to manage any sort from dubious circumstance (Felder, 2004). They may need to comprehend complex issues in their work floor that too absent a lot of insights concerning the assignment. They need to make sense of all alone. The specialists additionally need to work in a group domain in all the activity situations. They can't work alone and accomplish the objectives. On the off chance that we take a gander at the present individuals who are now utilized for a decade ago in the wake of experiencing building instruction, they are hesitant to work in a group domain. Likewise, they need critical thinking aptitudes when they are facing any issue all of a sudden. The expansion of designing understudies in top salaried occupations diminished and whittling down rate expanded in light of absence of abilities in the people. The primary issue with the building understudy before was the customary method of educating in a uninvolved study hall condition. At present, the understudies are being instructed in field by giving them genuine issues which they have resolve by working in a group. One of the fundamental point of having Engineering as a stream is to prepare students into an issue solver who can think seriously on some random issue anytime. He will be a long lasting student and will attempt to determine everything which come his direction. Subsequently, having an issue based learning in Engineering is a lot of basic at this point and all organizations should center towards the equivalent. Issue Based Learning advancing Critical Thinking in Engineering Students As talked about in the above areas, the future Engineers ought to be prepared to handle any sort of circumstance. For this, they should be dynamic and become a basic scholar. A basic mastermind is a one who comprehends the issue from all aspects and attempt to discover elective answers for the issue. Out of the options which have been discovered, the individuals will discover the proper arrangement and resolve the issue. The Problem Based Learning approaches centers around the students delicate aptitudes advancement just as giving them the alternative to pick their own examination to think of the arrangement (Ary, 2010). The exploration advances the basic intuition inside the student. The student experiences broad research by perusing numerous new things and afterward break down those with the assistance of devices. This build up a feeling of fearlessness inside them. Accordingly, basic believe is advanced. The Engineering students needs a basic reasoning methodology whether a student is a Computer Science unhitched male or a mechanical. Everybody needs to have thinking and conveying capacities to exceed expectations in their profession. The nation needs individuals who can get up in their feet and fathom complex issues in this way helping other people. PBL helps the student in accomplishing the equivalent. The designers likewise experience automatic executions inside the PBL technique. These causes the students to become sure that they can experience any sort of circumstances and can attempt to determine it. The individuals inside the designing educational program are given over the issue sheet which they need to talk about as a gathering and afterward think of the best way to deal with move in the direction of that issue. This is the most ideal approach to show a student and husband to be him/her to exceed expectations later on (Savin-Baden, 2000). End In the above segment, we talked about that the down to earth critical thinking approaches are currently observed as the standard method of instructing in the majority of the rumored organizations. The method of encouraging will again show signs of improvement barely any years down the line. The Problem Based Learning is at present the most ideal manner by which basic reasoning can be advanced in Engineering Students. These assistance the understudy to pick up information which they can really use in reality. The hypothetical information is less helpful with regards to genuine situations. The understudies in an Engineering Institute can be solicited to manage any sort from questionable circumstance. They may need to comprehend complex issues in their work floor that too absent a lot of insights concerning the errand. Consequently, having an issue based learning in Engineering is a lot of basic at this point and all organizations should center towards the equivalent. References Ary, D., Jacobs, L. C., Sorensen, C.

Learn about our Medical Review Board Steven Gans, MD Updated on February 13, 2020 Ghislain Marie David de Lossy / Getty Images More in Relationships Violence and Abuse Spouses & Partners LGBTQ If you know or suspect that someone is a victim of domestic violence, you might feel clueless about the best way to help. Dont let a fear of saying the wrong thing prevent you from reaching out. Waiting for the perfect words could keep you from seizing the opportunity to change a life. The world for many domestic abuse victims can be lonely, isolated, and filled with fear. Sometimes reaching out and letting them know that you are there for them can provide tremendous relief. How to Help Support a Domestic Violence Victim Use the nine tips that follow to help you support someone in this vulnerable situation.   Reasons Why Domestic Abuse Happens Make Time for Them If you decide to reach out to an  abuse victim, do so during a time of calm. Getting involved when tempers are flaring can put you in danger.  Also, make sure to  set aside plenty of  time in case the victim decides to open up. If the person decides to disclose years of pent-up fear and frustration, you will not want to end the conversation because you have another commitment. Start a Conversation You can bring up the subject of domestic violence by saying “I’m worried about you because …..” or “I’m concerned about your safety… or I have noticed some changes that  concern me... Maybe youve seen the person wearing clothing to cover up bruises or noticed that the person has suddenly become unusually quiet and withdrawn. Both can be  signs of abuse. Let the person know that  you will be discreet about any information disclosed. Do not try to force the person to open up; let the conversation unfold at a comfortable pace. Take it slow and easy. Just let the person know that you are available and offering a sympathetic ear. Listen Without Judgment If the person does decide to talk, listen to the story without being judgmental, offering advice, or suggesting solutions. Chances are if you actively listen, the person will tell you exactly what they need. Just give the person the full opportunity to talk. You can ask clarifying questions, but mainly just let the person vent their feelings and fears. You may be the first person in which  the victim has confided. Learn the Warning Signs Many people try to cover up the abuse for a variety of reasons, and learning the warning signs of domestic abuse can help you help them:Physical Signs:Black eyesBusted lipsRed or purple marks on the neckSprained wristsBruises on the armsEmotional Signs:Low self-esteemOverly apologetic or meekFearfulChanges in sleeping or eating patternsAnxious or on edgeSubstance abuseSymptoms of depressionLoss of interest in once enjoyed activities and hobbiesTalking about suicideBehavioral Signs:Becoming withdrawn or distantCanceling appointments or meetings at the last minuteBeing late oftenExcessive privacy concerning their personal lifeIsolating themselves from friends and family Believe the Victim Because domestic violence is more about control than anger, often the victim is the only one who sees the dark side of the perpetrator. Many times, others are shocked to learn that a person they know could commit violence. Consequently, victims often feel that no one would believe them if they told people  about the violence.  Believe the victims story and say so. For a victim, finally having someone who knows the truth about their struggles  can bring a sense of hope and relief. Offer the victim these assurances: I believe youThis is not your faultYou dont deserve this. Validate the Victims Feelings Its not unusual for victims to express conflicting feelings about their partner and their situation. These feelings can range from: Guilt and angerHope and despairLove and fear If you want to help, it is important that you validate her feelings by letting her know that having these conflicting thoughts is normal.  But it is also important that you confirm that violence is not okay, and it isnt normal to live in fear of being physically attacked. Some victims may not realize that their situation is abnormal because they have no other models for relationships and have gradually become accustomed to the cycle of violence.  Tell the victim that violence and abuse arent part of healthy relationships. Without judging, confirm to her that her situation is dangerous, and you are concerned for her safety. Reasons Why Victims Stay It can be hard to understand why someone you care about would seemingly choose to stay in an abusive or unhealthy relationship. Here are a few reasons why its not easy to part ways.Fear of harm if they leaveThey still love their partner and believe they will changeTheir partner promised to changeA strong belief that marriage is for better or worseThinking the abuse is their faultStaying for the childrenLack of self-confidenceFear of isolation or lonelinessPressure from family, community, or churchLack of means (job, money, transportation) to survive on their own Offer Specific Help and Support Help the victim  find support and resources. Look up telephone numbers for shelters, social services, attorneys, counselors, or support groups. If available, offer brochures or pamphlets about domestic violence. Youll also want to help them get information on any laws regarding protective orders/restraining orders and child custody information. You can search state by state for legal information on  WomensLaw.org. If the victim  asks you to do something specific and you are willing to do it, dont hesitate to help. If you are unable to, try to find other ways the need can be met. Identify their strengths and assets, and help them build and expand upon them, so they find the ?motivation to help themselves. The important thing is to let them know that you are there for them, available at any time. Just let them know the best way to reach you if help is needed. If possible, offer to go along for moral support to the police, court, or lawyer’s office. Let the person know they are not alone and help is available. Call the National Domestic Violence Hotline at 1-800-799-7233 for immediate assistance and a referral to nearby counseling services or support groups. Help Form a Safety Plan Help the victim create a safety plan  that  can be put into action if violence occurs again or if they decide to leave the situation. Just the exercise of making a plan can help them visualize which steps are needed and to prepare psychologically to do so. Because victims who leave their abusive partners are at a 75 percent  greater risk of being killed by their abuser than those who stay, it is extremely important for a victim to have a personalized safety plan before a crisis occurs or before they decide to leave. Help the victim think through each step of the safety plan, weighing the risks and benefits of each option and ways to reduce the risks. Be sure to include the following in the safety plan: A safe place to go in an emergency, or if they decide to leave homeA prepared excuse to leave if they feel threatenedA code word to alert family or friends that help is neededAn escape bag with cash, important documents (birth certificates, social security cards, etc.), keys, toiletries, and a change of clothes that can be easily accessed in a crisis situationA list of emergency contacts, including trusted family or friends, local shelters, and domestic abuse hotline How dangerous is the situation? Take the Danger Assessment Quiz  to find out. What Not to Do or Say to a Domestic Violence Victim Although there is no right or wrong way to help a victim of domestic violence, you want to avoid doing anything that will make the situation worse. Here are some donts the experts suggest you avoid: Dont... Bash the abuser. Focus on the behavior, not the personality.Blame the victim. Thats what the abuser does.Underestimate the potential danger for the victim and yourself.Promise any help that you cant follow through with.Give conditional support.Do anything that might provoke the abuser.Pressure the victim.Give up. If she is not willing to open up at first, be patient.Do anything to make it more difficult for the victim. When to Call the Police If you know that violence is actively occurring, call 9-1-1 immediately. If you hear or see physical abuse taking place, call the police. The police are the most effective way to remove the immediate danger to the victim and their children. There are no situations in which children should be left in a violent situation. Do whatever is necessary to ensure their safety, even if it means going against the wishes of your victim friend or the wishes of the abuser. In actively violent situations, calling child protective services is not the problem, its part of the solution. A Word From Verywell Although your natural impulse will want to be to rescue someone you care about from domestic violence, the person being abused needs to make the ultimate decision of whether to leave and get help. Keeping this in mind will help ensure that you support them no matter their decision and continue to provide them with a loving and safe friendship. 9 Ways to Prevent Teen Dating Violence

An Idealized Model in Physics

I once heard an acronym for the best pieces of physics advice I ever got: Keep It Simple, Stupid (KISS). In physics, we are typically dealing with a system that is, in reality, very complex. For an example, lets consider one of the easiest physical systems to analyze: throwing a ball. Idealized Model of Throwing a Tennis Ball You throw a tennis ball into the air and it comes back, and you want to analyze its motion. How complex is this? The ball isnt perfectly round, for one thing; it has that weird fuzzy stuff on it. How does that affect its motion? How windy is it? Did you put a little bit of spin on the ball when you threw it? Almost certainly. All of these things can have an impact on the motion of the ball through the air. And those are the obvious ones! As it goes up, its weight actually changes slightly, based on its distance from the center of the Earth. And the Earth is rotating, so perhaps that will have some bearing on the relative motion of the ball. If the Suns out, then theres light hitting the ball, which may have energy repercussions. Both the Sun and the Moon have gravitational effects on the tennis ball, so should those be taken into account? What about Venus? We quickly see this spiraling out of control. Theres just too much going on in the world for me to figure out how all of it impacts on me throwing the tennis ball? What can we do? Use in Physics In physics, a model (or idealized model) is a simplified version of the physical system that strips away the unnecessary aspects of the situation. One thing that we dont typically worry about is the physical size of the object, nor really its structure. In the tennis ball example, we treat it as a simple point object and ignore the fuzziness. Unless its something were specifically interested in, well also ignore the fact that its spinning. Air resistance is frequently ignored, as is wind. The gravity influences of the Sun, Moon, and other heavenly bodies are ignored, as is the impact of light on the surface of the ball. Once all of these unnecessary distractions are stripped away, you can then begin focusing on the exact qualities of the situation that youre interested in examining. To analyze the motion of a tennis ball, that would typically be the displacements, velocities, and gravity forces involved. Using Care With Idealized Models The most important thing in working with an idealized model is to make sure that the things youre stripping away are things that are not necessary for your analysis. The features that are necessary will be determined by the hypothesis that youre considering.   If youre studying angular momentum, the spin of an object is essential; if youre studying 2-dimensional kinematics, it may be able to ignore it. If youre throwing a tennis ball from an airplane at high altitude, you may want to take into account wind resistance, to see if the ball hits a terminal velocity and stops accelerating. Alternately, you may want to analyze the variability of gravity in such a situation, depending on the level of precision you need. When creating an idealized model, make sure that the things youre eliminating are traits that you actually want to eliminate from your model. Carelessly ignoring an important element isnt a model; its a mistake. Edited by Anne Marie Helmenstine, Ph.D.

M1903 Springfield Rifle - World War I

The M1903 Springfield rifle was the primary rifle used by the United States Army and Marine Corps during the first several decades of the 20th century. Officially designated United States Rifle, Caliber .30-06, Model 1903, it was a bolt-action rifle that utilized a five-round magazine. The M1903 was used by the American Expeditionary Forces in World War I and was retained after the conflict. It was not replaced as the standard American infantry rifle until the introduction of the M1 Garand in 1936. Despite this change, the M1903 was still in use during the early campaigns of World War II. In the years after the war, only the M1903A4 sniper rifle variant remained in the inventory. That last of these were retired during the early years of the Vietnam War. Background Following the Spanish-American War, the U.S. Army began seeking a replacement for its standard Krag-JÃ ¸rgensen rifles. Adopted in 1892, the Krag had shown several weaknesses during the conflict. Among these was a lower muzzle velocity than the Mausers employed by Spanish troops as well as a difficult to load magazine which required the insertion of one round at time. In 1899, attempts were made to improve the Krag with the introduction of a high-velocity cartridge. These proved unsuccessful as the rifles single locking lug on the bolt proved incapable of handling the increased chamber pressure. Development Design Over the next year, engineers at the Springfield Armory began developing designs for a new rifle. Though the U.S. Army had examined the Mauser in the early 1890s prior to selecting the Krag, they returned to the German weapon for inspiration. Later Mauser rifles, including the Mauser 93 used by the Spanish, possessed a magazine fed by a stripper clip and a greater muzzle velocity than its predecessors. Combining elements from the Krag and the Mauser, Springfield produced its first operational prototype in 1901. Soldier with M1903 Springfield. U.S. Army Center for Military History Believing they had achieved their goal, Springfield began tooling its assembly line for the new model. Much to their dismay, the prototype, designated M1901, was declined by the U.S. Army. Over the next two years, the U.S. Army laid out a variety of changes which were incorporated into the M1901s design. In 1903, Springfield presented the new M1903, which was accepted into service. Though the M1903 was a composite consisting of the best elements from several prior weapons, it remained similar enough to the Mauser that the U.S. Government was forced to pay royalties to Mauserwerke. M1903 Springfield Cartridge: .30-03 .30-06 SpringfieldCapacity: 5 round stripper clipMuzzle Velocity: 2,800 ft./sec.Effective Range: 2,500 yds.Weight: approx. 8.7 lbs.Length: 44.9 in.Barrel Length: 24 in.Sights: Leaf rear sight, barleycorn-type front sightAction: Bolt-action Introduction The M1903 was officially adopted on June 19, 1903 under the official designation of United States Rifle, Caliber .30-06, Model 1903. In contrast, the British and Commonwealth forces used the Lee-Enfield Rifle. Moving into production, Springfield built 80,000 of the M1903 by 1905, and the new rifle slowly began to replace the Krag. Minor changes were made in the early years, with a new sight added in 1904, and a new knife-style bayonet in 1905. As these alterations were implemented, two major changes were introduced. The first was a shift to pointed, spitzer ammunition in 1906. This led to the introduction of the .30-06 cartridge that would become standard for American rifles. The second change was a shortening of the barrel to 24 inches. World War I During testing, Springfield found that the M1903s design was equally effective with a shorter, cavalry-style barrel. As this weapon was lighter and more easily wielded, it was ordered for the infantry as well. By the time the US entered World War I in April 1917, 843,239 M1903s had been produced at Springfield and the Rock Island Arsenal. Equipping the American Expeditionary Forces, the M1903 proved lethal and efficient against the Germans in France. During the war, the M1903 Mk. I was produced which allowed for the fitting of a Pedersen device. Developed in an effort to increase the M1903s volume of fire during assaults, the Pedersen device allowed the rifle to fire .30 caliber pistol ammunition semi-automatically. World War II After the war, the M1903 remained the standard American infantry rifle until the introduction of the M1 Garand in 1937. Much beloved by American soldiers, many were reluctant to switch to the new rifle. With the entry of the US into World War II in 1941, many units, both in the U.S. Army and Marine Corps, had not completed their transition to the Garand. As a result, several formations deployed for action still carrying the M1903. The rifle saw action in North Africa and Italy, as well as in the early fighting in the Pacific. A GI with the 36th Infantry Division cleans his M1903 Springfield, equipped with sniper scope. Public Domain The weapon was famously used by the U.S. Marines during the Battle of Guadalcanal. Though the M1 replaced the M1903 in most units by 1943, the older rifle continued to be used in specialized roles. Variants of the M1903 saw extended service with the Rangers, Military Police, as well as with Free French forces. The M1903A4 saw extensive use as a sniper rifle during the conflict. M1903s produced during World War II were often made by Remington Arms and the Smith-Corona Typewriter Company. Later Use Though it was reduced to a secondary role, the M1903 continued to be produced during World War II by Remington Arms and Smith-Corona Typewriter. Many of these were designated M1903A3 as Remington requested several design changes to improve performance and simplify the manufacturing process. With the conclusion of World War II, most M1903s were retired from service, with only the M1903A4 sniper rifle being retained. Many of these were replaced during the Korean War, however the U.S. Marine Corps continued to use some until the early days of the Vietnam War.

The Roles and Achievements of Prime Ministers Free Essays

Name Tutor Course Date The Roles and Achievements of Prime Ministers John a Macdonald and Laurier Sir John a MacDonald was the first prime minister of Canada and was the dominant representative of the Canadian confederation. He was born on the 11th January 1815 and passed on 6th June. His term in office was 18 years long which places him to the second longest serving prime minister in Canada. We will write a custom essay sample on The Roles and Achievements of Prime Ministers or any similar topic only for you Order Now He is the only one to ever win six majority governments (Hennessy 12). As for Sir Wilfrid Laurier, he was the seventh prime minister, Born on 20th November 1841 and passed on on the 17th February 1919. He was the first francophone prime minister and was considered one of the countries superb statesmen. As compared to his counter part John a MacDonald, sir Wilfrid was also in the list of the longest serving prime ministers in Canada although him coming in as position four. Sir Wilfrid also contributed to the expanding of the confederation. Sir John MacDonald was born in Glasgow Scotland was the third in a family of five while Sir Wilfrid laurier was born in Saint-lin Canada East and was the 7th generation of his family. MacDonald’s parents decided that he should become a lawyer after his completion of schooling. It was a great choice for a boy who seemed to really admire studying and beside that he had an urgent to start earning cash in order to support his family since his fathers business ventures were failing. As compared to Macdonald Lauriers’ father was well up and by the age of eleven he was sent to study in new Glasgow. Macdonald had a rather sorrowful and tragedous private life. When Sir Macdonald first came into office he was faced with major opposition. Nova Scotia was already threatening to withdraw from the confederation; the Anglo-American relationships were in a poor state. In 1867 the first general elections were held and this is where MacDonald had his first major achievement. He was able to bring together Nova Scotia New Brunswick and the province of lower and Upper Canada to form the state of Canada of which guaranteed him election stress free. MacDonald’s main vision was to enlarge the country and bring it together in unity. Under his rule he rought British Colombia, PIE, and great North West territories into Canada all this for ? 300,000 (about $11,500,000 in modern Canadian dollars). Macdonald’s still biggest achievement as a prime minister was the building of the Trans continental railway which was completed in 1891 (Leonardo 219). He also managed to create a god relationship with the United States rising to the challenge of the Northwest rebellion and his balancing of French and English interests in accept able terms for most. Sir Wilfrid Laurier is known to have had a number of accomplishments as a prime minister. To begin with he was able to establish the department of labour and external affairs, he also managed to recruit immigrants into the west, and in 1905 he oversaw the creation of two provinces Alberta and Saskatchewan into the confederation which saw the creation of the last two provinces in the Northwest Territories (Picknett, Prince, Prior Brydon 290). He also saw the beginning of the two new transcontinental railways although the project was filled with scandals. He also made a deal with the united state for lower rates on natural products. The two prime ministers are to date considered being the greatest of all time. This Great statesmen had a couple of similarities if we scrutinses them properly. One similarity was that both of them were students of law. MacDonald studied law in Toronto where he traveled by boat whereas sir Wilfrid studied law in New Glasgow. These two men had a vision of the expansion of the country of Canada since both of them contributed to the increase of the confederation. Sir MacDonald helped bring the provinces of Upper and Lower Canada, Nova Scotia, and New Brunswick together in 1867 to form Canada while Sir Wilfrid Laurier had the provinces of Alberta and Saskatchewan created in 1905 which saw the last spit of the Northwest Territories. Sir Macdonald oversaw the establishments of the first transcontinental railway and Sir Wilfred Laurier also oversaw the establishment of tow more transcontinental. Sir MacDonald negotiated the relation ship with the United States and this was also exhibited by sir Wilfrid. The above similarities signify that both of the prime ministers were both devoted and dedicated to the development of Canada. These similarities only signify their similarities in ensuring a proper Canada but these two men had other similarities because they were both the first in whatever they did. MacDonald was the Prime minister of Canada while Sir Wilfrid Laurier was the first francophone prime minister. In the common life Sir MacDonald and sir laurier had a couple of differences . Sir MacDonald came from a family that was not all that well up as compare do to sir Wilfred, he studied law in order to be able to put a meal on his families table since all his fathers ventures were crumbling as compared to Wilfred who studied Law as his passion. Sir Wilfred and Sir MacDonald left a legacy in Canada and are both commemorated in big ways. Both of them have the pleasure of having holidays celebrated in their hournor; they both have avenues named in their respect such as the Laurier Avenue. These two statesmen had very minimal similarities and difference and these was due to their characters but both will live to be legends as far as Canada is concerned. Works Cited Hennessy, Peter.

Summer Of 42 Essay he book A Farewell to Arms, written by Ernest Hemingway, is a classic about the love story of a nurse and a war ridden soldier. The story starts as Frederick Henry is serving in the Italian Army. He meets his future love in the hospital that he gets put in for various reasons. I thought that A Farewell to Arms was a good book because of the symbolism, the exciting plot, and the constant moving of the main character. The symbolism in A Farewell to Arms is very much apparent. Ernest Hemingway has always been one who is big on the symbolism of night as being bad. To the main character in Hemingways novels, nights have always been a sign of death, or something negative to happen. Another one of the symbolisms in A Farewell to Arms is when Henry tries to escape from the Italian army by jumping off one of the ships the army was traveling on and running away from the army. This symbolism was the water that he jumped into was a symbolism of the new, clean life that he was going to live from now on. At this time, Henry goes off and finds his wife to be.

It had a very good story line, which was a love story that ended up in a tragedy. The main characters wife got pregnant and she was off to have her baby when problems started occurring. They had to have a caesarean, and the baby dies, and when the mother of the child starts to hemorrhage Henry knows that it was over for his wife and he was right. From the beginning of the book until the end, the action was up. Ever since the front page Henry was traveling around to different towns so it was not boring for the reader. That made it very interesting for the reader because it was always a new town coming up so they were being introduced in the new characters quite often. As the story goes on, the reader is not introducing as many new people, but they are still traveling around quite a bit. Hemingway has a way with arranging the plots of all his stories. They all have that right timing to them. He always introduces only people that will affect the story, he does not introduce someone who will be in the scene for five minutes and then leave. I felt that the authors planning on putting this noveltogether was very good. Ernest Hemingway has always been one of the worlds best known classic writers. His style and technique of symbolism is much different than others. He uses then in very strong ways that you the reader does not always pick up. I am sure that I missed some of the symbolism that went on in the book. I picked up a few though and they were very interesting. I recommend this to anyone who is interested in a love story that does not get too intimateEnglish

Learning and Cognition Relationship between Learning and Cognition

Learning and Cognition Relationship between Learning and Cognition Learning starts from the very first days of a human life. People learn how to walk, how to perform complicated tasks and how to cooperate with other individuals. People have tried to understand what learning is throughout centuries. There are various approaches to this issue. However, all researchers agree that learning is closely connected to such concept as cognition.Advertising We will write a custom essay sample on Learning and Cognition: Relationship between Learning and Cognition specifically for you for only $16.05 $11/page Learn More Though, there are researchers who challenge this assumption stating that there are cases when learning is possible without cognition. To understand the relationship between cognition and learning, it is important to take a closer look at the concept of learning. Firstly, it is necessary to provide a proper definition for the concept of learning. Some people see learning as â€Å"an outcome of the social experiences in a nd out of schools to which young people are exposed† (Yates McLeod, 2011, p. 230). However, it is clear that learning goes beyond classroom environment. People acquire knowledge and gain new skills in a variety of settings. Ellstrom (2011, p. 238) provides a more comprehensive definition of learning, â€Å"learning is a process of knowledge acquisition through experienced-based changes in cognition or action†. Therefore, learning happens in various settings, but it is associated with certain changes, i.e. acquisition of knowledge and skills which is, in its turn, connected with cognition. It is necessary to note that behavior plays an important role in learning. For instance, active people can be exposed to a great amount of information which can be learnt easily (Ellstrom, 2011). At the same time, some people find it rather difficult to concentrate as they are often distracted by numerous things. Lack of concentration can lead to difficulties while learning. Notably, those who are less active are not exposed to new information as they tend to be in settings they know perfectly well, i.e. they remain on the safe side. Interestingly, behavior and learning are regarded in terms of the evolutionary approach (Ellstrom, 2011). Ability to acquire knowledge and actively use it is associated with ability to survive in the animal world. This can also be applied to the contemporary world as people who acquire more knowledge have lots of opportunities, e.g. they get better jobs and get more resources, etc.Advertising Looking for essay on psychology? Let's see if we can help you! Get your first paper with 15% OFF Learn More Apart from different types of behavior, there are two types of learning. Thus, learning can be explicit and implicit (Yates McLeod, 2011). Explicit learning is often associated with education. People are explicitly exposed to certain information. They try to use a variety of strategies to facilitate learning. For instance, students try to memorize data and they train the skills they have acquired. Adult people also have to learn new skills, e.g. professional, communicative, leadership skills, etc. As far as implicit learning is concerned, it happens without training or extra effort. As has been mentioned above, people are often exposed to a lot of information. They memorize facts, faces, places without extra effort. This is a characteristic feature of human cognitive ability to perceive and process information (Shanks, 2010). Therefore, the two types of learning help people gain knowledge and develop cognitive abilities. Clearly, learning and cognition are interrelated. Researchers claim that there can be no learning without cognition (Shanks, 2010). Admittedly, people learn things after they have processed information cognitively. It is easy to provide an example to this concept. A 5-year-old child can be given a task to build a toy house. The child will be given major parts of the house, i .e. 4 walls and the roof. There will be no difficulties and the child will be able to build the toy house as he has the necessary experience, i.e. he/she has seen lots of houses. However, if the child will be shown (and given instructions on) how to build the toy house quickly, he/she will spend less time building the house as the child has seen how to do it, i.e. have acquired experience. Thus, the child looks at and touches the parts of the house and gets information about the material and shape. The child pictures houses he/she has seen in his/her life. This enables the child to put the parts of the house together. Next time, the child will be able to complete the same task much faster. Admittedly, if the child had not had the instructions and certain experience, he/she would not be able to perform the task. Nonetheless, some researchers claim that cognition is not an indispensible part of learning as learning without cognition is also possible (Shanks, 2010). However, these theo ries are yet to be researched and grounded. To sum up, it is possible to note that learning and cognition are interrelated. People get the vast majority of knowledge due to their cognitive abilities. People perceive objects and gain experience through learning, implicit or explicit. It is also important to add that behavior plays an important role in learning, especially when it comes to implicit learning. However, further research is required as there are lots of learning mechanisms which are unclear. It is also necessary to take a closer look at the correlation between learning and cognition.Advertising We will write a custom essay sample on Learning and Cognition: Relationship between Learning and Cognition specifically for you for only $16.05 $11/page Learn More Reference List Ellstrom, P.E.

Venomous Sea Snake Facts (Hydrophiinae and Laticaudinae)

Venomous Sea Snake Facts (Hydrophiinae and Laticaudinae) Sea snakes include 60 species of marine snakes from the cobra family (Elapidae). These reptiles fall into two groups: true sea snakes (subfamily Hydrophiinae) and sea kraits (subfamily Laticaudinae). The true sea snakes are most closely related to Australian cobras, while kraits are related to Asian cobras. Like their terrestrial relatives, sea snakes are highly venomous. Unlike terrestrial cobras, most sea snakes are not aggressive (with exceptions), have small fangs, and avoid delivering venom when they bite. While similar to cobras in many respects, sea snakes are fascinating, unique creatures, perfectly adapted to life in the sea. Fast Facts: Venomous Sea Snake Scientific Name: Subfamilies Hydrophiinae and LaticaudinaeCommon Names: Sea snake, coral reef snakeBasic Animal Group: ReptileSize: 3-5 feetWeight: 1.7-2.9 poundsLifespan: Estimated 10 yearsDiet: CarnivoreHabitat: Coastal Indian and Pacific OceanPopulation: UnknownConservation Status: Most species are Least Concern Description Yellow-bellied sea snake (Hydrophis platurus), illustrating the body shape of a true sea snake. Nastasic / Getty Images Aside from analyzing its DNA, the best way to identify a sea snake is by its tail. The two types of sea snakes have very different appearances because they have evolved to live different aquatic lives. The true sea snakes have flattened, ribbon-like bodies, with oarlike tails. Their nostrils are on top of their snouts, making it easier for them to breathe when they surface. They have small body scales and may lack belly scales entirely. True sea snake adults range from 1 to 1.5 meters (3.3 to 5 feet) in length, although a length of 3 meters is possible. These snakes crawl awkwardly on land and may become aggressive, although they cannot coil to strike. You can find both true sea snakes and kraits in the sea, but only sea kraits crawl efficiently on land. A sea krait has a flattened tail, but it has a cylindrical body, lateral nostrils, and enlarged belly scales like a terrestrial snake. A typical krait color pattern is black alternating with bands of white, blue, or gray. Sea kraits are somewhat shorter than true sea snakes. An average adult krait is about 1 meter in length, although some specimens reach 1.5 meters. Habitat and Distribution Sea snakes are found throughout the coastal waters of the Indian and Pacific oceans. They do not occur in the Red Sea, Atlantic Ocean, or Caribbean Sea. Most sea snakes live in shallow water less than 30 meters (100 feet) deep because they need to surface to breathe, yet must seek their prey near the sea floor. However, the yellow-bellied sea snake (Pelamis platurus) may be found in the open ocean. The so-called California sea snake is Pelamis platurus. Pelamis, like other sea snakes, cannot live in cool water. Below a certain temperature, the snake is unable to digest food. Snakes may be found washed up on shores in the temperature zone, typically driven by storms. However, they call the tropics and subtropics their home.   The so-called California sea snake is actually the yellow-bellied sea snake. Auscape / UIG / Getty Images Diet and Behavior The true sea snakes are predators that eat small fish, fish eggs, and young octopuses. True sea snakes may be active during the day or at night. Sea kraits are nocturnal feeders that prefer to feed on eels, supplementing their diet with crabs, squid, and fish. While they have not been observed feeding on land, kraits return to it to digest prey. Some sea snakes host the sea snake barnacle (Platylepas ophiophila), which hitches a ride to catch food. Sea snakes (kraits) may also host parasitic ticks. Sea snakes are preyed upon by eels, sharks, large fish, sea eagles, and crocodiles. Should you find yourself stranded at sea, you can eat sea snakes (just avoid getting bitten). You can tell this is a krait because it has nostrils on either side of its snout. Todd Winner/Stocktrek Images / Getty Images Like other snakes, sea snakes need to breathe air. While kraits surface for air regularly, true sea snakes can remain submerged for around 8 hours. These snakes can breathe through their skin, absorbing up to 33 percent of needed oxygen and expelling up to 90 percent of waste carbon dioxide. The left lung of a true sea snake is enlarged, running much of its body length. The lung affects the animals buoyancy and buys it time underwater. The nostrils of a true sea snake close when the animal is underwater. While they live in the oceans, sea snakes cannot extract fresh water from the saline sea. Kraits may drink water from land or the sea surface. True sea snakes must wait for rain so they may drink the relatively fresh water floating on the seas surface. Sea snakes can die of thirst. Reproduction and Offspring Olive sea snake two days old, Reef HQ Aquarium, Townsville, Queensland, Australia. Auscape / UIG / Getty Images The true sea snakes may be oviparous (lay eggs) or ovoviviparous (live birth from fertilized eggs held within the females body). The mating behavior of the reptiles is unknown, but it may be linked to the occasional schooling of large numbers of snakes. The average clutch size is 3 to 4 young, but as many as 34 young may be born. Snakes born in the water may be nearly as large as adults. The genus Laticauda is the only oviparous group of true sea snakes. These snakes lay their eggs on land. All sea kraits mate on land and lay their eggs (oviparous) in rock crevices and caves on shore. A female krait may deposit from 1 to 10 eggs before returning to the water. Sea Snake Senses Olive sea snake, Hydrophiidae, Pacific ocean, Papua New Guinea. Reinhard Dirscherl / Getty Images Like other snakes, sea snakes flick their tongues to gain chemical and thermal information about their environment. Sea snake tongues are shorter than those of regular snakes because its easier to taste molecules in water than in air. Sea snakes ingest salt with prey, so the animal has special sublingual glands under its tongue that allow it to remove excess salt from its blood and expel it with a tongue flick. Scientists dont know much about sea snake vision, but it appears to play a limited role in catching prey and selecting mates. Sea snakes have special mechanoreceptors that help them sense vibration and movement. Some snakes respond to pheromones to identify mates. At least one sea snake, the olive sea snake (Aipysurus laevis), has photoreceptors in its tail that allow it to sense light. Sea snakes may be able to detect electromagnetic fields and pressure, but the cells responsible for these senses have yet to be identified. Sea Snake Venom Sea snakes bear close observation, but may bite if threatened. Joe Dovala / Getty Images Most sea snakes are highly venomous. Some are even more venomous than cobras! The venom is a deadly mixture of neurotoxins and myotoxins. However, humans rarely get bitten, and when they do, the snakes rarely deliver venom. Even when envenomation (venom injection) does occur, the bite may be painless and initially produce no symptoms. Its common for some of the snakes small teeth to remain in the wound. Symptoms of sea snake poisoning occur within 30 minutes to several hours. They include headache, stiffness, and muscle pain throughout the body. Thirst, sweating, vomiting, and a thick-feeling tongue may result. Rhadomyolisis (muscle degradation) and paralysis ensue. Death occurs if the muscles involved in swallowing and respiration are affected. Because bites are so rare, antivenin is next to impossible to obtain. In Australia, a specific sea snake antivenin exists, plus the antivenin for the Ausatralian tiger snake may be used as a substitute. Elsewhere, youre pretty much out of luck. The snakes are not aggressive unless they or their nest are threatened, but its best to leave them alone. The same caution should be applied to snakes washed up on beaches. Snakes may play dead as a defense mechanism. Even a dead or decapitated snake may bite via reflex. Conservation Status Habitat destruction and over-fishing are threats to sea snake survival. Hal Beral / Getty Images Sea snakes, as a whole, are not endangered. However, there are some species on the IUCN Red List. Laticauda crockeri is vulnerable, Aipysurus fuscus is endangered, and Aipysurus foliosquama (leaf-scaled sea snake) and Aipysurus apraefrontalis (short-nose sea snake) are critically endangered. Sea snakes are difficult to keep in captivity, due to their specialized diets and habitat requirements. They need to be housed in rounded tanks to avoid damaging themselves on corners. Some need to be able to exit the water. Pelamis platurus accepts goldfish as food and can survive captivity. Animals That Resemble Sea Snakes Garden eels look a bit like snakes. Mark Newman / Getty Images There are several animals that resemble sea snakes. Some are relatively harmless, while others are venomous and more aggressive than their aquatic cousins. Eels are often mistaken for sea snakes because they live in the water,  have a serpentine appearance, and breathe air. Some species of eels can give a nasty bite. A few are poisonous. Some species can deliver an electric shock. The sea snakes cousin is the cobra. Cobras are excellent swimmers that can deliver a deadly bite. While they are most often found swimming in freshwater, they are at ease in coastal saltwater, too. Other snakes, both on land and water, may be confused with sea snakes. While the true sea snakes may be recognized by their flattened bodies and oar-shaped tails, the only visible trait distinguishing sea kraits from other snakes is a somewhat flattened tail.

Treatment of Autism Research Paper Example | Topics and Well Written Essays - 2500 words

Treatment of Autism - Research Paper Example It is shown by the fact that identical or monozygotic twins have more chances to get the disease than do the dizygotic twins or the siblings. Conditions affecting the language skills are more prevalent in the family of the patient. Other chromosomal and neurological disorders are also present in the family with autism. Other factors which can also prove causative include; Diet, changes in the digestive tract, metal poisoning specifically with mercury, metabolic disorders in which the body is not able to utilize the vitamins and the minerals and hypersensitivity to some of the vaccines. There are a group of people who are of the view that mercury is a part of some of the multi dose vaccines as thimerosal so in their opinion these vaccines can cause autism but this a misperception as The American Academy of Pediatrics, and The Institute of Medicine (IOM) has agreed to the fact that all the children who are currently diagnosed as autism’s patients, vaccination is not the cause of this disease in a single case even. It should also be considered that the benefits of the vaccination outweighs the disadvantages so vaccination should not be discontinued on account of diseases like autism as most of the vaccines are single dose prescription and thimerosal is not a constituent of any of the single dose vaccine. Treatment: B. F. Skinner who was a psychologist showed that the patients who are diagnosed cases of autism can benefit maximum from participating in Applied Behavior Analysis Training which is also known as ABA training; though there are other treatment strategies also available for the management of autism patients but ABA training proves to be much superior than the other treatment modalities. The cost of using this technique as the treatment modality should be brought into consideration before initiation of the therapy. ABA Training: It is also known as Intensive Behavioral Intervention. There are differences between these two kinds of therapy but most o f the parents as well as layman usually consider both of these as a form of intense treatment plan which primarily includes careful observation and studying the patient usually the affected child and the treatment mainly applies the principles of Operant Conditioning which was1st presented in the theories presented by B. F. Skinner. A study of the children affected by autism was carried out by Ivar Lovaas in 1980’s and it was evident from the results of the study that main principles of ABA can be used in a program designed to treat the patients of autistic disorders. This study showed marked improvement in the patients of autism if these techniques are used in a proper manner. There are many techniques which are currently the part of ABA management system and one of the principle techniques is Discrete Trial Teaching (DTT) which is used extensively nowadays. The main aim of this technique is to maximize the learning process in the affected children and it is useful in the de velopment of most of the skills e.g. cognitive, social, behavioral, fine motor, play as well as it can also be used to accelerate the ability of the children to help them at times. DTT usually involves the fragmentation of the main skill into several sub skills and then each sub skill is taught to the children intensely at a time. In actual practice, repeated sessions are planned with the child and involve prompting and then the prompt is faded to make sure the successful learning of that particular skill by

Jesse Owens Biography

Jesse Owens Biography 1936: The Olympic Games were being held in Berlin, Germany. Berlin was buzzing with excitement. The Nazi Party was currently in control at the time. Hitler deemed that his perfect race would dominate the games. Jesse Owens proved him wrong. Beating many Nazis, he became one of the best runners in history. Jesses life leading up to his performance at the 1936 Olympic Games was a hard one, being a sickly child living in a poor family. On September 12, 1913, James Cleveland Owens, named J.C later, was born on a farm in Oakville, Alabama to Henry and Mary Emma Owens. They were both former slaves. He was the youngest of ten brothers and sisters. He grew up as a sickly child, constantly getting pneumonia and other illnesses. He had many other lung problems as well. In his daily life, he would work on the farm and going to a small, one room school house nine miles away from his home. When he was working on the farm he would help pick cotton out of the fields. He would pick about 100 pounds of cotton a day. This was hard on the childs lungs, and with his lung problems, this wasnt a good thing. When he was 10, his family moved to Cleveland, Ohio to find better work. This transition was hard for this family from the deep South. There, he worked part time at a cobblers shop and got to attend a real school. On the first day of school, he told the teacher that his name was J.C. She misunderstood his southern accent and thoug h he said Jesse. He was to shy to correct her, so this is how his name came to be. By the time Jesse reached junior high, he was wise of the ways of the streets. There he met two people that would change the rest of his life. The first was Minnie Ruth Solomon, a young woman whose family had moved north from a farm in the south, just like Jesses family had just done. As high schoolers, they both fell in love fast. The second was Charles Riley, the man who introduced Jesse to track and field. He saw potential in him, even though he hadnt shown any special athletic ability. To help Jesse, Charles beefed up his diet to help build up his muscles and help his still delicate legs. After this change in diet, Jesse impressed his new coach by running the 100- yard dash in 11 seconds, which was a remarkable time for a 15-year-old. After a while, Charles entered Jesse in other events, including the long and high jump. During this time of Jesses success, the Great Depression started. If not for his mother, Jesse would have had to leave school. But she insisted that he enroll at East Technical High School. Soon after Jesses enrollment, Charles Riley was hired as an assistant coach. Jesse continued to progress under Rileys coaching. He was named captain of the track and field team at his school and was elected as the student body president. This was a huge accomplishment because he went to a predominantly white school. This went on to show his outgoing personality and his athletic accomplishments. His accomplishments in high school were a pre-cursor to his success to come. In 1933 he entered Ohio State University under an unofficial scholarship. To make up for the money he worked part time jobs, such as a night elevator operator, pumped gas, worked in a library, and served as a page in the Ohio Statehouse. Jesse made his big appearance at the 1935 Big Ten meet in Michigan. The meet established his presence by finishing well in his events, winning three of his four. At the Big Ten Championship that may, he surprised people by breaking five world records and tying another, all in a span of 45 minutes. He almost didnt compete because of a sore back that he had because of a fall down a flight of stairs. He eventually convinced his coach to let him compete. To test his back, he ran the 100- meter dash. He ran an amazing time of 9.3 seconds. That is where he became a national star. Three years before, Ruth Solomon, his soon to be wife, had given birth to a daughter. When Ruths parents, they wouldnt allow her to see Jesse. Although they lived apart, Jesse sti ll sent money to help Ruth pay for their daughters needs. In July of 1935, he married Ruth Solomon in Cleveland. The following year, he was suspended from the Ohio State track and field for poor grades. He worked hard to raise his average, just in time for the spring. He went to the Olympic trials for the 1936 summer Olympics. He dominated the sprint events there and emerged on the top of the American squad. Jesses amazing collegiate career was his introduction to the nation and the world and a sign of a soon to be great Olympian. The crowd roared with excitement as the opening ceremony of the 1936 Olympics games in Berlin began. With Adolf Hitler present, thousands of people stood and saluted the Nazi flag, showing their patriotism for their motherland. Hitler claimed that the Aryan race was going to dominate the games, but Jesse proved that Hitlers perfect race wasnt so perfect after all. Though, Jesse couldnt have gone to these games if it hadnt been for the decision of the United States Olympic Committee. As first, they were planning on boycotting the games because it might show support of the Nazi partys racial beliefs and anti- Semitic policies. Evidence was being presented that Jewish athletes were not being treated fairly. The decision was made by the Amateur Athletic Union, the biggest non-profit organization in the nation that helps promote amateur athletics and physical fitness. The group in favor of no boycott won by two and a half votes. That meant that there would be a squad going to the Olympic Games. So, at that very Olympic Games, Jesse Owens showed his superiority in track and field. At these games, he stood at 510 and weighed 165 lbs. In Berlin, he won his first gold medal in the 100- yard dash with a time of 10.3. He then went on to capture the long jump with a world record breaking distance of 26 feet 5 inches. During this event, an incident happened that almost had Jesse disqualified from the event. During his practice jump, the judges counted it as his first jump. The next jump he jumped over the line, causing a fault on his part. Finally, on the last jump, he jumped his record- breaking leap, defeating his competition German Competition, Luz Long. After this event, Hitler refused to shake his hand after his win over Long. He then went on to go a record- shattering 20.7 in his 200- meter. He returned home a celebrity, hailed in open car parades and banquets. After the Olympics, Long and Owens became close friends for a long time. This relationship showed true sport smanship that was to be showed at the games. Jesses Olympic experience not only showed his athletic ability, but he was also a voice for anti- racism saying that there was no dominant race. Jesses life after the Olympics was a very sentimental time for him. Not only did he advertise for certain companies, he had jobs with certain associations. The things that he did after the Olympics earned him great sums of money. He talked at banquets, worked for endorsements, advertised, and much more. He was well known for talking to youth groups, professional organizations, civic meetings, sports banquets, PTA, church organizations, brotherhood and black history programs, as well as high schools and college ceremonies. He also had many jobs. He was a public relation s representative and consultant to many corporations, including Atlantic Richfield, Ford, and the United States Olympic Committee. He went on tour as a leader of a 12- piece orchestra. He went barnstorming with basketball and baseball teams and put on running exhibitions. But, the greatest job that he loved most was a playground director in Cleveland. He also worked with underprivileged children there too as a board me mber and former director of the Chicago Boys Club. He eventually couldnt take the prolonged separation from his family, so he decided to open a Laundromat in the area of his home. In 1940 he suffered a double major loss when his mother died and the Internal Revenue Service got after him for back taxes. That forced him to close his business, lowering his income. Feeling bad for not working harder as a student, he was determined to go back to Ohio State to receive a degree since the loss of his business. Even though he tried hard, it was to difficult for him and he quit after a year. When World War II started he was hired by the government to organize physical- fitness programs. This helped him earn income after the fall of his company. After that, he took a satisfying job with the Ford Motor Company in Detroit to look after the social need of thousands of black workers on the Ford payroll. After the war, he moved to Chicago with his family. He then when into the public relations busi ness, using his still- famous personality for the use of a variety of companies. His job became a boost when the Associated Press named him the greatest track-and-field athlete in history in 1950. As the years passed, he watched in sadness as his records were broken. He was a supporter of the black protest movement, but annoyed by it all at once. His still delicate lungs were still not holding up, and on March 31, 1980, James Cleveland Owens died of lung cancer. Jesse Owens is said to have been one of the most accomplished and astounding runner in history. He beat many German athletes, proving that the Hitlers perfect race was not perfect. He took the lead for many generations of athletes to come to work for you want and do not give up. The Berlin Olympics broke the popular idea of society that there is race that is dominant over another and that to do something successful, you must be one race. Jesse Owens was the man that proved society wrong.

Reducing Death Penalty Costs Essay

Abstract In this paper, I will be evaluating the death penalty in the United States and ways that costs can be cut to make it much more of a viable option. â€Å"Using conservative rough projections, the Commission estimates the annual costs of the present system $137 million per year (California Commission on the Fair Administration of Justice, 2008). What does an individual death row inmate get for millions of tax payers’ dollars you ask? This includes; housing, garments, meals, health care, mental care, pre-trial and trial, unlimited appeals and petitions. I think that the limit for appeals at the state level should be only 3 appeals and 2 at the federal level. If an inmate knew how many state and federal appeals they had before they were done, we wouldn’t see a waste of appeals on frivolous things. This would cut legal costs and free up the courts dockets a little more by not allowing death row inmates to appeal over every little thing. Reducing Death Penalty Costs Although the total accumulated cost of the death penalty sentence does vary from state to state one thing can be said; it is extremely exorbitant. â€Å"Using conservative rough projections, the Commission estimates the annual costs of the present system $137 million per year (California Commission on the Fair Administration of Justice, 2008). What does an individual death row inmate get for millions of tax payers’ dollars you ask? This includes; housing, garments, meals, health care, mental care, pre-trial and trial, unlimited appeals and petitions. Why would a public defender object or his boss for this matter object to getting their bills paid by the tax payers’? There needs to be stricter legal and privilege guidelines for death row inmates and attorneys that defend them. If prison systems would make stricter guidelines and regulations for death row inmates then costs would go down exponentially. There needs to be limitations on how many times a death row inmate can appeal and petition their case. I think that the limit for appeals at the state level should be only 3 appeals and 2 at the federal level. If an inmate knew how many state and federal appeals they had before they were done, we wouldn’t see a waste of appeals on frivolous things. This would cut legal costs and free up the courts dockets a little more by not allowing death row inmates to appeal over every little thing. These continuing moves that are plaguing our legal system which has increased the average duration of their stay on death row. If the number of appeals is not a good solution then only allow appeals that are relative to their case in proving their innocence. Check out the chart and look at the increase in length of death row durations we have seen over the last three decades. [pic](Death Penalty Information Center, 2012). Another way to cut costs for death row inmates is to shorten the time in between sentencing and execution. By limiting the number of appeals a death row inmate is allowed will significantly shorten their wait to be executed. As the graph above shows, in 1984 there were only 74 months wait between sentencing and execution. In the years to follow, the length of time between sentencing and execution grew exponentially to 178 months in 2010. That is almost 15 years for an inmate to accrue legal fees through unlimited appeals that they do not have to pay for. The length of time that U.S. inmates spend on death row has gotten increasingly longer in recent years, and raises questions about the constitutionality of this added punishment (Death Penalty Information Center, 2012). When an individual is sentenced to a death penalty sentence, they are automatically entitled to unlimited appeals and the tax payers are going to pay for this through taxes. The inmates have at their disposal almost u nlimited resources on the tax payer’s dime. In my opinion, if a death row inmate cannot prove their innocence after the allotted 3 state appeals and 2 federal appeals with the financial allotment of $250,000, then the financial responsibility should fall to the inmate and/or their families. We, as citizens, should not be forced to have to pay for these murders to continue to take up the courts time with frivolous appeals. Food expenses also need to be seriously cut down. Death row inmates are eating much better than many of America’s low income families who make minimum wage and are unable to buy food. The average household income in The United States is $51,914 per year (U.S. Department of Commerce, 2012). These people are in prison, not a day spa. In Connecticut, the Department of Correction serves up three meals a day for the bargain-basement price of $2.42 per inmate – roughly what a bag of fries and a Coke will cost you at McDonald’s (Kauffman, 2012). I believe this is still more than these criminals deserve. Below is the link to see a sample menu of what the inmates are being fed at Connecticut Department of Corrections: http://courantblogs.com/investigative-reporting/wp-content/uploads/2012/03/Prison-Menu.pdf. Our children do not even get this good of quality of food in schools, why should the inmates. Arizona Sheriff Joe Arpaio, who is reputed to have cut food costs down to 40 cents a day with a strategy that, included serving green surplus bologna to inmates (Kauffman, 2012). Many people share Sheriff Arpaio’s ideology or he wouldn’t keep getting re-elected. The inmates should only get bologna sandwiches and water. They should make their own bread from scratch also to cut down the costs of buying sliced bread. If the inmates want any kind of fresh fruits and vegetables then they must work to earn the right to a garden. The inmates’ families should be responsible for the costs of the seeds and paying for th e water to use on the gardens. Death row inmates should also not be allowed to live in air conditioned facilities. Death row prisoners are served breakfast and dinner in their cells, can usually mingle with others in the outdoor exercise yards while eating their sack lunches, and have exclusive control over the television, CD player or other diversions in their cells (Williams, 2009). â€Å"Death row inmates probably have the most liberal telephone privileges of anyone in state custody,† said Terry Thornton, spokeswoman for the California Department of Corrections and Rehabilitation, explaining that they need ready access to their attorneys and can often make calls from their cells over a phone that can be rolled along the cell-block (Williams, 2009). Those on death row are also allowed more personal property inside their cells, to accommodate their voluminous legal documents without infringing on the 6 cubic feet of snacks and entertainment devices allowed each prisoner, said Lt. Sam Robinson, spokesman for San Quentin (Williams, 2009). They lost that ability when they committed those crime in which caused them to be sentenced to death. They should not be allowed to play games, watch television, have personal radios/CD players, unlimited access to the telephone and the inmates and all calls should be recorded, and they should not be allowed contact visits in private, unlike inmates in other parts of the prison. American prisons should also stop providing free 24 hour health care to their inmates. Make the families of the inmate pay for any services rendered, whether inmates see an on call doctor or go to the emergency room. There is no reason that working taxpayers’ should have to foot yet another outrageous bill for inmates. The average cost of healthcare for a typical American family of four in an employer- sponsored health plan in 2012 is $20,728 (Wells Media Group, Inc., 2012). Death row inmates should not be allowed to receive free health care while hard working Americans are struggling to make ends meet with minimum wages and still trying to be able to afford healthcare for their families. How does this seem fair, you may wonder? Well, it is not where near the category of fair. â€Å"Anti-Terrorism and Effective Death Penalty Act of 1996. The Act, which affects both state and federal prisoners, restricts review in federal courts by establishing tighter filing deadlines, limiting the opportunity for evidentiary hearings, and ordinarily allowing only a single habeas corpus filing in federal court. Proponents of the death penalty argue that this streamlining will speed up the death penalty process and significantly reduce its cost, although others fear that quicker, more limited federal review may increase the risk of executing innocent defendants† [(Bohm, 1999 and Schabas, 1997)]. In conclusion, if our prison systems would make stricter guidelines and regulations for death row inmates then costs would go down exponentially. There needs to be stricter legal and privilege guidelines for death row inmates and attorneys that defend them. If prison systems would make stricter guidelines and regulations for death row inmates then costs would go down exponentially. Another way to cut costs for death row inmates is to shorten the time in between sentencing and execution. By limiting the number of appeals a death row inmate is allowed will significantly shorten their wait to be executed. And finally, death row inmates should have all of their luxuries that are not necessities to live. Death row inmates would pray for death to come quicker because there are the bare minimum.

History and Origins of Wheat Domestication

Wheat is a grain crop with some 25,000 different cultivars in the world today. It was domesticated at least 12,000 years ago, created from a still-living ancestor plant known as emmer. Wild emmer (reported variously as T. araraticum, T. turgidum ssp. dicoccoides, or T. dicocoides), is a predominantly self-pollinating, winter annual grass of the Poaceae family and Triticeae tribe. It is distributed throughout the Near Eastern Fertile Crescent, including the modern countries of Israel, Jordan, Syria, Lebanon, eastern Turkey, western Iran, and northern Iraq. It grows in sporadic and semi-isolated patches and does best in regions with long, hot dry summers and short mild, wet winters with fluctuating rainfall. Emmer grows in diverse habitats from 100 m (330 ft) below sea level to 1700 m (5,500 ft) above, and can survive on between 200–1,300 mm (7.8–66 in) of annual precipitation. Wheat Varieties Most of the 25,000 different forms of modern wheat are varieties of two broad groups, called common wheat and durum wheat. Common or bread wheat Triticum aestivum accounts for some 95 percent of all the consumed wheat in the world today; the other five percent is made up of durum or hard wheat T. turgidum ssp. durum, used in pasta and semolina products. Bread and durum wheat are both domesticated forms of wild emmer wheat. Spelt (T. spelta) and Timopheevs wheat (T. timopheevii) were also developed from emmer wheats by the late Neolithic period, but neither has much of a market today. Another early form of wheat called einkorn (T. monococcum) was domesticated at about the same time but has limited distribution today. Origins of Wheat The origins of our modern wheat, according to genetics and archaeological studies, are found in the Karacadag mountain region of what is today southeastern Turkey—emmer and einkorn wheats are two of the classic eight founder crops of the origins of agriculture. The earliest known use of emmer was gathered from wild patches by the people who lived at the Ohalo II archaeological site in Israel, about 23,000 years ago. The earliest cultivated emmer has been found in the southern Levant (Netiv Hagdud, Tell Aswad, other Pre-Pottery Neolithic A sites); while einkorn is found in the northern Levant (Abu Hureyra, Mureybet, Jerf el Ahmar, Gà ¶bekli Tepe). Changes During Domestication The main differences between the wild forms and domesticated wheat are that domesticated forms have larger seeds with hulls and a non-shattering rachis. When wild wheat is ripe, the rachis—the stem that keeps the wheat shafts together—shatters so that the seeds can disperse themselves. Without hulls, they germinate rapidly. But that naturally useful brittleness doesnt suit humans, who prefer to harvest wheat from the plant rather than off the surrounding earth. One possible way that might have occurred is that farmers harvested wheat after it was ripe, but before it self-dispersed, thereby collecting only the wheat that was still attached to the plant. By planting those seeds the next season, the farmers were perpetuating plants that had later-breaking rachises. Other traits apparently selected for include spike size, growing season, plant height, and grain size. According to French botanist Agathe Roucou and colleagues, the domestication process also caused multiple changes in the plant that were generated indirectly. Compared to emmer wheat, modern wheat has shorter leaf longevity, and a higher net rate of photosynthesis, leaf production rate, and nitrogen content. Modern wheat cultivars also have a shallower root system, with a larger proportion of fine roots, investing biomass above rather than below ground. Ancient forms have built-in coordination between above and below ground functioning, but the human selection of other traits has forced the plant to reconfigure and build new networks. How Long Did Domestication Take? One of the ongoing arguments about wheat is the length of time it took for the domestication process to complete. Some scholars argue for a fairly rapid process, of a few centuries; while others argue that the process from cultivation to domestication took up to 5,000 years. The evidence is abundant that by about 10,400 years ago, domesticated wheat was in widespread use throughout the Levant region; but when that started is up for debate. The earliest evidence for both domesticated einkorn and emmer wheat found to date was at the Syrian site of Abu Hureyra, in occupation layers dated to the Late Epi-paleolithic period, the beginning of the Younger Dryas, ca 13,000–12,000 cal BP; some scholars have argued, however, that the evidence does not show deliberate cultivation at this time, although it does indicate a broadening of the diet base to include a reliance on wild grains including the wheat. Spread Around the Globe: Bouldnor Cliff The distribution of wheat outside of its place of origin is part of the process known as Neolithicization. The culture generally associated with the introduction of wheat and other crops from Asia to Europe is generally the Lindearbandkeramik (LBK) culture, which may have been made up of part immigrant farmers and part local hunter-gatherers adapting new technologies. LBK is typically dated in Europe between 5400–4900 BCE. However, recent DNA studies at Bouldnor Cliff peat bog off the northern coast of mainland England have identified ancient DNA from what was apparently domesticated wheat. Wheat seeds, fragments, and pollen were not found at Bouldnor Cliff, but the DNA sequences from the sediment match Near Eastern wheat, genetically different from LBK forms. Further tests at Bouldnor Cliff have identified a submerged Mesolithic site, 16 m (52 ft) below sea level. The sediments were laid down about 8,000 years ago, several centuries earlier than the European LBK sites. Scholars suggest that the wheat got to Britain by boat. Other scholars have questioned the date, and the aDNA identification, saying it was in too good a condition to be that old. But additional experiments run by British evolutionary geneticist Robin Allaby and preliminarily reported in Watson (2018) have shown that ancient DNA from undersea sediments is more pristine than that from other contexts.   Sources Avni, Raz, et al.
