Title: Childhood Obesity General Goal: To Inform Specific Goal: I want my audience to know or understand that childhood obesity has become an epidemic. Thesis Statement: While there are numerous variables of childhood obesity, the two fundamental causes are eating an excessive amount and exercising too little. Introduction I. According to the World Health Organization, â€Å"the number of obese children ages 0-5 years increased from 32 million globally in 1990 to 42 million in 2013.† A. Really open your eyes the next time you go out. B. What you will see is what has seemingly become the new trend among children. C. According to the article, â€Å"Children’s Life Expectancy Being Cut Short by Obesity† from the New York Times, the current generation may have a shorter life span than their parents. D. Children’s waistlines are expanding at rapid speed. 1. The CDC reports that â€Å"from 1976-1980, children ages two to five had an increase of obesity from 5%to 10.4%. From 2007-2008, children ages 6-11 had an increase of obesity from 6.5% to 19.6%.† 2. Sources vary on the actual percent, but the general consensus is that about 15%-33% of American children are obese. II. After fully researching this topic, the root of childhood obesity has become very clear. III. Today, I will explain the two leading causes of childhood obesity: eating in excess and exercising too little. Body I.

By Means Of Power Essay Example For Students

By Means Of Power Essay By Means of PowerBoth Adrienne Rich and Audre Lorde, in their respective poems entitled Power, convey the idea that ones identity and sense of worth is defined by what they are willing to give up. This message is energized by the emotion the authors evoke through their ability to communicate a sense of experience. It is this experience as mothers and highly intelligent feminists that allow us to feel the unconditional caring towards humanity they are encouraging in their poems. In the opening lines of Lordes Power, The difference between poetry and rhetoric/is being/ready to kill/yourself/instead of your children(1-5), she immediately stresses the importance of putting your child before yourself. This is a metaphor for putting the needs of what is truly important before the needs of oneself. It is not only stated simply and bluntly, but the way the lines are broken up accent the idea. Ready to kill(3) is on its own line, while yourself(4) is on the next. This is the theme that is running throughout the entire poem. In the next section of Lordes poem she describes a dreamlike situation. This is where her son has been shot, probably in the face. Although blood from his punctured cheeks and shoulders/is the only liquid for miles(9-10), my mouth splits into dry lips(12). With the death of her boy she is willing to sacrifice her own need of any quenching of her lips. She is thirsting for the wetness of his blood(14) but it is more important to resist the temptat ion, trying to make power out of hatred and destruction(18). The power displayed in the third section of Lordes Power is that of hatred. A policeman has shot down a 10-year-old in Queens(21). This he justifies by saying I didnt notice the size or nothing else/only the color(26-27). This officer has taken the power entrusted into him by the citizens and used it for his own good. Or not even his own good but what he might consider beneficial to his people. This directly opposes what Lorde was saying at the beginning of the poem. He is not ready to kill himself instead of his children. And although he has actually killed a boy here that is not the only thing he has killed. He killed the idea of allowing someone else to have interests above what he might agree with. That same officer was acquitted for his crimes in the following section of the poem. The people who had the power to bring him to justice abused that power and by setting him free. The 11 white men who said they were satisfied/justice had been done(31-32) also used their power in numbe rs to corrupt the power of the one women who probably had the decency and power to know right from wrong. they had dragged her 410 black womans frame/over the hot coals of four centuries of white male approval/until she let go of the first real power she ever had(35-37). She had the opportunity to make a difference and she let her power go to the wayside. In looking at Adrienne Richs Power one senses the same theme as in that of Lordes Power. This is the tenet that one must put the good of a greater or another before that of oneself. This is what gives people true power and is evident in Richs depiction of Marie Curie. Marie Curie was born in Poland and would become famous for her research into radioactivity. She died as a result of this research and the over-exposure to the element she was working with. In living with the knowledge that she was suffering from ailments due to her work Curie she became a more empowered and powerful person. The idea that she must have known she suffered from radiation sickness(7) yet continued on in the search proved that her wounds came from the same source as her power(17). The wounds were her power. Curie knew that she had suffered and did not back down or fall to the wayside, she was up for the challenge. The element/she had purified(9) was important for the greater good of mankind, and Curie put th at before herself. The convictions that the people these two authors herald in their works are some of the noblest. There is no way to understand the power these women feel in standing for what they believe in. The belief that doing for others is more important than doing for yourself and that in turn you will receive a sense of power that only comes in not asking for it is greater than any sense of power taken by force or fraud.

Reforestation Essays - Forestry, Biology, Natural Environment

Reforestation The purpose of this written report is to inform the reader about the concerns and facts involved with reforestation. Reforestation began in Ontario after World War II. What happened was, professional foresters were assigned to an area and became responsible for its well being. Under the Crown Timber Act, long term management was prepared. Then the many steps needed to rebuild a forest began. Included in this report will be information on the effects of cutting and replanting, such as Carbon Dioxide, and Global Warming. Following this will be methods for planning a forest, and how they are conveyed before planting in a forest begins. There are many reasons why forests are cut down. One is to benefit economically, with furniture and home building. But there is also another reason. Arguments say "the United States could help slow the atmospheric accumulation of carbon dioxide by replacing old-growth forests with faster-growing young trees". A new study of young and old forests says how this is in fact not true. Loggers have said that new trees pull the carbon dioxide better than old trees, and this may seem true, but it is not. There is one point being overlooked from all of this. The older, larger trees can store much, much more carbon dioxide than a new tree could. By cutting and burning these magnificent seasoned trees, the CO2 is being released back into the atmosphere. These releases of carbon dioxide add up in our surroundings, only to intensify Global Warming. Although this shows what happens when one burns and cuts down old forests, one must still plant new trees for long term plans, not letting them grow for a few years, to then cut them down. There are many methods for planning a forest. The simplest method of replanting a forest is to leave it to nature. A suitable seed bed in which trees will readily take root is integral for successful regeneration. Reducing competition by eliminating grass, weed or shrubs is another requirement in securing a new cro p of trees. These will sprout to produce seedlings. Though the weeds were eliminated before, they still grow back, and because of this poor, quality trees will grow. Another method though, is to create a planned forest, where new conifers are grown from seed in a special nursery. Seeding is a reforestation technique used mainly in the Boreal forest area where fire or logging tends to leave no or very little seeds for growth. In specific cases, Ministry staff seed the area with treated tree seeds. Following this is the planting. In many cases, planting is the only means of initiating a new forest. Up to 80 000 000 trees are planted annually in Ontario on Crown and private land. Usually immature forests have to be tended to. Once situated, a new crop needs intermittent care for the next 60 to 100 years. This means continuing protection from fires, disease and insects and routine thinning to focus the growth on selected crop trees. Before a forest can be grown, certain procedures must first occur. Collecting and processing seeds is one of them. Tree flowers fertilized by blowing winds or insects generate seed, in a time of somewhere within 1 to 2 years. Seed collecting from the woods must be timed with periodically occurring good seed years. Angus, near Barrie, is where all forest tree seed collection is co-ordinated. Stock of seeds can value up to $500 000. Usually this is around 3 billion seeds from 59 tree classes. In summary of the aforesaid, trees are very valuable to the human race economically and for health. Without trees the environment could worsen to the point where we would be living on one large dessert. We must remember that forest do not grow as easily as they used to because of fires and other disasters. This is why many forests are planned, and cared for. Most of us will never now how they turn out because for a forest to completely grow, it needs within anywhere from 60 to 100 years or more. There are many reasons why we should have reforestati on. One being mostly that we need forest to live! Without forests, or any type

Mrs.Dalloway Rhetorical Analysis Essays

Mrs.Dalloway Rhetorical Analysis Essays Mrs.Dalloway Rhetorical Analysis Essay Mrs.Dalloway Rhetorical Analysis Essay Essay Topic: Mrs Dalloway Throughout the novel, Wolf employs chromatic imagery whilst describing the advancing society of modern London, portraying the lively mood of its citizens . During World War l, England faces a very dark time in its history. However after Armistice D ay, England goes through a very joyous time period full of life and technological advances. Woo Ifs chromatic imagery includes the recurring image of the red 5), as well as ma NY other color, including white, violet, red, deep orange(1 5), to describe the flowers of the SST ore that Claries sited in the beginning of the book. Later, Wolf employs a plethora of silver images to accentuate Calamaris home, along with Calamaris green dress and yellow ha t to accentuate her style. With all of these colors brightening up Calamaris life, the read easily assumes that Claries lives a joyous life brought on by her affluent life. Law 2 Ironically enough, Calamaris apparently vivid life actually possesses a very gloom my side as expressed in Calamaris gloomy tone. While Claries walks through her lively neighborhood to go buy her beautiful flowers, dark thoughts cloud her mind. She realizes her I joss of identity brought upon by her marriage which will result in her being Mrs.. Daylong; n tot even Claries any more; being Mrs.. Richard Daylong. (1 1) Instead of being happy that Clara as married an affluent man in her community, she seems to regret her decision. As the story progresses, Claries reveals that she fears she married Richard to achieve financial stability y, not her own happiness. This decision focuses on the modernist obsession to marry for fin uncial reasons instead of personal desires. Calamaris relationship with her daughter Elizabeth also faces corruption in the modern era. For a part of the book Elizabeth spends a lot of time with her history teacher, Mrs.. Kalmia, who dislikes Claries. This relationship between Claries and Kalmia places a strain on Calamaris relationship with Elizabeth. In addition, Claw risks continuously searches for a deeper meaning in her life; an answer she feels try Lully empty without. Claries worries that her materialistic desires and her obsession with mundane e things such as parties and appearances corrupt her life. So Calamaris intimate relationships tit her husband and daughter fragment in the midst of the modernist characteristics. Virginia Wolf employs a very unique writing style in Mrs.. Daylong by telling the story mainly through inner monologues. This writing style mixes true dialogue bet en characters and the inner dialogue with themselves, revealing the difference between what the e characters say and what the characters think. In many parts of the book, this creates a very strand GE situation. For example, when Peter and Claries first encounter in the book, Peter tells Clara as about his new eve but at the same time he thinks about how much he loves Claries. Like WI SE, Claries Law 3 discusses her happy new life with Richard, but later on second guesses her De concision to reject Peter. If the two simply spoke their minds, then they would not face such tragic c situations. Also, later in the book Richard wants to tell Claries how much he loves her, but he does not. Again, the reader knows how Richard feels, but Claries does not. Finally Septum s peaks nonsense throughout the novel, but he keeps a lot of what he wants to say trapped in hi s mind. If Lucrative longingly listens to Septum instead of claiming insanity, their relationship woo old blossom. Instead, Septum bottles up his emotions until he tragically ends his life. This further exemplifies the fragmentation of relationships during the modern era. Relation unships survive when partners can communicate, but due to the Modern eras Obsession with saving time, people create less intimate relationships with people since they do not spend as much h time getting to know each other. This emotional distance creates communication problems h arming the damaged relationship even further. Instead of splitting her novel into chapters, Virginia Wolf lets Mrs.. Daylong flow freely, just as a day does. However, she does split the day up into different it me periods usually signified by a bell or a clock. In the beginning of the novel, Big Ben strikes. (4) signifying the the time, and as the story progresses, more clocks remind the characters of t he time. This constant ringing throughout the story not only states the time, but it reminds the characters that time moves on. As they all worry about their appearances and their parties an d their relationships ND their hats, time continues to move forward. The ringing bell reminds the m of their mortality, awakening the mot do what they must do. It also brings them out of the state of reminiscing on memories and it reminds them to focus on the present instead of the past. D ruing the modern times, people advance so they can save time. Time becomes a valuable com oddity to people; so Law 4 valuable that they forget to spend time appreciating nature and appreciating people in their lives. The modernist obsession with time brought about the ultimate fragmentation f intimacy, because suddenly people did not have time to waste on other people. As humans advance, they begin to lose their connection with their fellow man . As they obsess over doing things quickly for themselves, they forget to spend time to gather. As they begin to fear what people may think of them, they avoid speaking their minds . As humans cease factories communications with each other, they begin to separate complete y. If people fail to create relationships with each other, then they will never create a relationship with his or herself.

Examine the distinguishing features of HRM in Europe Essay

Examine the distinguishing features of HRM in Europe - Essay Example Cray& Mallory (1998) say it was a reaction against the more functional approach embodied in personnel management. Relative to this phenomenon is another growing trend which is globalization. Organizations and businesses have become global as a result of technological innovations, and the introduction of more development in communications and transportation. The internet and information technology have revolutionized the way organizations and businesses work. Globalization is not new. This has been with the world business and economy since the centuries after Columbus and da Gama started their voyages from the Mediterranean. Globalisation has revolutionized businesses and organisations. A commonly accepted definition of globalization by economists, says Van Der Bly (2005, p. 875), is that it is the â€Å"international economic integration that can be pursued through policies of ‘openness’, the liberalization of trade, investment and finance, leading to an ‘open economy.† The importance of borders between different countries is reduced, and similar events and phenomena in countries throughout the world are more easily linked. 1.) HRM is now considered the determinant factor in the success or failure in international business (Black et al., 1999, cited in Scullion & Paauwe, 2004), and also the success of global business depends most importantly on the quality of management in the MNC (Stroh and Caligiuri, 1998, cited in Scullion & Paauwe, 2004); â€Å"HRM emphasizes that employees are critical to achieving sustainable competitive advantage; that human resources practices need to be integrated with the corporate strategy, and that human resource specialists help organizational controllers to meet both efficiency and equity objectives† (Bratton, 1999, p. 11). One of the first explicit statements of the HRM concept was made by the Michigan School (Fombrun et al, 1984, cited in Armstrong, 2006, p. 4), which held that HR systems and the organization

The Road to the Ocean - Essay Example â€Å"You’re too young to drive,† her mom said. â€Å"The road is not for kids, I mean, teens,† her dad added. When Leah’s face fell and her eyes moistened, her mother came toward her, only to be met by the â€Å"hands off† hand gesture. In other words, the gesture said: â€Å"Talk to the hand that would never hold you again for a million years.† Leah felt betrayed. She expected her father to back her up, to say yes to her favorite and only daughter. She knew her mom would say no. Mothers created the word â€Å"paranoia.† But fathers, no, fathers were supposed to be a lot cooler, a lot more trusting. She knew that her father would knock on her door and explain himself. She wanted to turn him away. But she never could. Her father was a military official and when he was there, she knew how precious time was. When Lt. Col. James Madison knocked on his daughter’s door, Leah said: â€Å"You know it’s open.† She could im agine him sighing. His bulky frame covered the whole door. He was massive and scary-looking. But for Leah, he was only her father. Her Daddy. He was the best father in the whole world, up until that moment when he betrayed her and did not let her drive. It was not even his car. And that thought made her angrier. She did not want to turn to him. She wanted him to see her straight and angry back, as she read her book, which she was not reading. But again, she failed. She glanced at him and there he was, 200 pounds of lean flesh, looking like a torn puppy. She imagined him whimper and she understood why her mother loved him so much. He was the biggest and most tender man ever. He loved them so fiercely. He would kill anyone who would deliberately hurt his wife and daughter. â€Å"Sorry Leah. I mean. I am not sorry, because I know what the streets are nowadays. I am just sorry I hurt your feelings and trust in me. One day†¦Oh, you know what I mean.† â€Å"No, I don’t . I’m a year shy of sixteen. What’s wrong with driving? I mean, learning to drive? It’s not like I’ll go off and have some random sex with any guy I meet at a club and get pregnant because of a stupid one-night stand.† â€Å"You know I trust you.† â€Å"It’s the world you don’t trust. I get it. But I don’t get it. Just please leave me alone. I want to go to another place, while staying here in my room.† â€Å"Oh, Leah. Okay, good night sweetie.† He waited. â€Å"Good night. Good night Daddy.† And she stood up to kiss him at the cheek. She had to tip toe to do it. She embraced him quickly. So much for her rebellious daughter act. She just could not stand being angry with her dad. Sunday, the next morning, Dad and Mom left Leah to Aunt Millie. They had second thoughts, because Millie was not exactly a very responsible adult. At the age of 31, she was still single and a party bug. But no one else was ava ilable, and Dad wanted to bring Mom somewhere special, because he was leaving for an overseas mission in a few days. They wanted to celebrate their wedding anniversary in advance. They left with creases on their foreheads. Before their SUV drove away, they both made the sign of the cross, praying that Millie would miraculously be an adult for just twelve hours of her life. Leah did not feel excited. She used to enjoy Millie’s companionship. But she was now sore and bitter, or more like sore from being bitter. Millie asked her what she wanted to do, and she said nothing. Millie promised her that they could do anything she wanted. Leah said she wanted to learn to

The efficiency of energy conservation Essay Example for Free

The efficiency of energy conservation Essay Safety In this experiments the staple that is fired has sharp ends to it and so it can be dangerous. So throughout this experiment I will wear goggles and work in an area away from others. Method 1) Set up the equipment as shown in the diagram on the first page. 2) Cut a 8cm of string 3) Attach the string to the weight holder (weight holder weighs 100g) 4) Attach the other end of the string to the elastic band. 5) Measure the extension of the elastic band and record it. 6) Get into the right position to record the height of the staple. 7) Cut the string and record the height to the nearest 5cm. 8) Repeat each test 3 times and then take an average of the height. 9) Repeat the same experiment using the next weight (200g). Obersavation and Recording To calculate the amount of elastic energy stored in the elastic band at different extension, I drew a graph based on the results shown below. The area under the graph is represented of the elastic energy stored at various extensions. From my graph, each 1cm   1cm square is represented ofThe elastic energy is an approximation. I have tried to be as accurate as possible whilst counting the squares. I found that the distance from the floor to the ceiling was 3. 32m and the distance the elastic band traveled from rest while attached to the clamp to the point where it hits the ceiling to be 2. 07m. From looking at the results we can see that the maximum height reached by the staple, the point where it hit the ceiling was when its extension was 10cm. From this I can calculate the amount of elastic energy stored in the band using my graph. I can also calculate the amount of energy transferred to the staple, ie the potential energy gained, by using the equation mgh. Evaluation In the experiment I was trying to measure the efficiency of the energy transfer for the staple fired into the air, by the elastic band. The energy conversion in the experiment is the transfer of elastic energy stored in the elastic band to potential energy gained by the staple after it has fired into the air. Elastic energy i Potential energy From looking at my results the general pattern is that an increase in extension increases the height of the staple that is fired. The graph I have produced, force extension graph also show this. The graph does not follow Hookes law, as the line is not straight. The values I collected for the elastic energy was 0. 170 J and energy converted into potential energy in the staple after it had been fired was 0. 041 J. The percentage efficiency for this energy transfer was 24. 1%. This means only a small amount of elastic energy was converted to potential energy and most of the energy had been lost. The reason for this could be due to the air resistance. I stretched the elastic at different lengths and observed how far the staple shot off as a result. At first the relationship between the extension and the distance was close, nearly the same. Then air friction could of decreased the distance traveled for a given stretch. This would mean that the staple would have gained less potential energy. Also this experiment involves the transformation of elastic energy to potential energy between the elastic and the staple. But when the elastic band is stretched and released this involve the transformation of elastic energy to kinetic energy so some energy could have been lost due to this kinetic energy. Another reason could be that when stretched, energy could of been lost as a form of heat. When the elastic band is stretched the rubber polymer chains become more orderly and H bonds form between these chains. This H bond formation is exothermic therefore the stretched elastic band will feel warm and heat will be lost. (Reversing this process (when unstretched), the polymer chains become disorderly, the H bonds break and as this is endothermic, heat is absorbed and the band feels cool. ) This heat energy lost will have an effect on the transfer of energy between the elastic band and the staple. To keep this experiment as accurate as possible I took 3 reading for each test and then I took an average. I used appropriate and reliable equipment and used them properly. When taking the results I will also draw the graph at the same time so if any chance an anomalous result does occurs I can go back and repeat the same test to get the right result. I also design the experiment so I would be as accurate as possible using the equipment from the lab. I thought that the experiment went well, the results that I got I thought was accurate and reliable. I thought that the experiment was well planned, reducing any factor that would lead to unreliable results.
