Bottled Water The Demand For Bottled Drinking Water

NJOKU Bottled Water The demand for bottled drinking water has been growing rapidly since the 1980s, increasing nearly 400% in the last decade according to the Council of Bottled Water Manufacturers, as a result of declining consumer confidence in the safety and quality of municipal water supplies. In response, individuals and businesses are purchasing bottled drinking water for use in their homes and offices. Free of contaminants and government-monitored, bottled waters are derived from protected springs or wells or are produced by purifying and processing water from public water supplies. Consumer demand for bottled water is expected to continue to increase, as water supplies worldwide are deemed undrinkable or unhealthy. According to a survey conducted by E-Works in 1988, more than 60% of consumers questioned about their purchase of bottled waters claimed taste was the primary reason for buying bottled water. Other reasons cited were safety and concerns about too many chemicals in tap water. To take advantage of this expanding market for drinking water, NJOKU Bottled Water has been established to provide home and office delivery of bottled water to the Wichita area. After months of extensive industry and market research, the company has developed a solid business plan to enter the market for bottled water. NJOKU will generate revenue as a result of the rental and sale of water coolers, as well as for the delivery of the three types of water: pure spring water,Show MoreRelatedEssay on Iceland Water - Case Study1221 Words   |  5 PagesWater from Iceland – Case Study Bottled water traditionally has been consumed in the United States by the wealthy.

Essay about Critical Pedagogy in Social Studies Education

Since the early twentieth century, educational theorists and researchers debated often about topics concerning the validity, purposes, and best approach to public education and the social studies discipline in the United States. Since the adoption of Ralph Tyler’s teacher-centered, essentialist approach to curriculum, John Dewey’s call for progressive reform and student-centered learning, and Paolo Freire’s call for an education that advocates social change and the destruction of social oppression, education pundits found themselves stuck between different goals, outcomes, and possibilities for teaching social studies. A review of recent literature proves that one of the goals, critical literacy, oftentimes stands at the center of†¦show more content†¦211; Freire, 2006, p. 219). Such topics as race, gender, class, media, and environment are often discussed in a classroom atmosphere dedicated to democracy and free thought (Wolk, 2003, p. 102; National Council of the Social Studies, 2008, p. 212; Wile, 2000, p. 171; Soares, et. al., 2010, p. 487). In doing so, critical literacy is often associated with Paolo Freire’s rationale for a social education that breaks down the oppressor-oppressed relationship that exists across the world to form a society that is just, humane, and equal (Freire, 2006, pp. 43-46). In order to achieve this, students must develop social justice skills that call for them to be active citizens of their society (Wolk, 2003, p. 102; National Council of the Social Studies, 2008, p. 211; Kumashiro, 2001, p. 8; Wineburg, et. al., 2004, 45). Many researchers and theorists stress the need to approach social studies from a critical literacy perspective. The idea that the current social studies curriculum supports a small privileged class while ignoring all other classes is one that is oftentimes associated with the present curriculum taught today (Kumashiro, 2001, p. 4). Additionally, researchers theorized that students bring stereotypes, myths, and a partial knowledge of various histories and cultures to the classroom.

Leadership in Thoughts from the Tao-te-Ching and The...

Leadership in Thoughts from the Tao-te-Ching and The Qualities of a Prince Lao-Tzu’s â€Å"Thoughts from the Tao-te Ching† and Machiavelli’s â€Å"The Qualities of a Prince† both have the ultimate goal of making better leaders. The tactics that each writer chooses to present as a guide for the leader are almost opposite of each other. Today’s American government would benefit from a combination of the two extreme ideas. Lao-Tzu’s laissez-faire attitude towards the economy, as well as his small scale, home defense military is appealing to a liberal person. Machiavelli’s attitude towards miserliness and lower taxes, while being always prepared for war, would appeal to a conservative person. The writers are in agreement on some issues, such as†¦show more content†¦A hated leader would invite a rebellion that would try to remove him from power. On the other hand, a leader should not be loved. Showing too much compassion will make the people think you are weak, and he would permit disorders to contin ue. Machiavelli urges the leader to always be personally armed, and preparing for war, even in peace time. The leader must continually train his body and mind for combat. He believes that people are fickle and greedy, so they will take whatever you give them. Ultimately, he believes the leader should do and say anything to keep the people happy, but when it comes down to it, what makes them happy may not be best for the state as a whole. An even mixture of both of these theories is the best for America. Something that our leaders in the United States in past years aimed for is middle of the road politics, appealing to both liberals and conservatives. Although I do not believe Machiavellis honesty policy would go over too well in the United States, I am sure his tactics are used by politicians in creating an appearance that people want to see. A good combination for our government today is for the president to not be personally armed, but have protection. He does not constantly train for war, but has an appointed official dedicated for that purpose.

War Is Unpredictable Free Essays

To an extent war is unpredictable, however the meaningless punishment and demoralising conduct is something that soldiers experience constantly throughout war. In Owen’s poem â€Å"Anthem for Doomed Youth† he diminishes the patriotism and heroism that is commonly associated with war and replaces it with depictions of the harsh punishment and perfidious death of youth in war. Correspondingly in his poem â€Å"Dulce et Decorum Est† he extends the theme of unpatriotic behaviour and hollow death and suggests that war is also a devilish and sinful practice, where nothing but death and hatred arise. We will write a custom essay sample on War Is Unpredictable or any similar topic only for you Order Now Contrastingly, in Stanley Kubrick’s war film â€Å"Full Metal Jacket† he does not look at death in war, but conversely the internal punishment that superior officers give to soldiers, harshly exploring the training and punishment soldiers receive before war. Ultimately, these three texts explore the lack of honour and worthless punishment that soldiers experience constantly in war, depicting war as a place of hatred and sin. In Owen’s poem â€Å"Anthem† he removes the common Romantic concepts of glory and triumph that were associated with war from the early 20th century and realistically explores the truly unpatriotic nature of the battlefield. His ideals contrasted the Romantic ideals of glory as well as the government and the media who exhibited war as valiant and fitting for the youth of the early 20th century. Instantly, Owen’s title of the poem contradicts the reader’s belief in the common war values where he pairs the terms â€Å"Anthem† and â€Å"Doomed Youth† juxtaposing with a gloomy and depressing description of the youth in war. Owen then compares the youth who â€Å"died as cattle† to an abattoir by using metaphor, emphasising the sheer amount of death that occurs on the battlefield, also suggesting that the youth are indiscriminately dying with no justification. Likewise, Owen uses juxtaposition to describe the sounds of war, in which he subverts the calming sound of â€Å"choirs† and depicts them as â€Å"demented†, illuminating the sound of screaming comrades in war and enhancing his anti-heroic view. Thus, Owen through his poem â€Å"Anthem† dishonours the common concepts of glory and triumph, and replaces them with â€Å"mockeries† of the dying youth in war, ultimately suggesting war unheroic and the soldiers deaths unglorified. On the contrary, Stanley Kubrick’s war film â€Å"FMJ† explores the internal and meaningless punishment that soldiers experience whilst training to become a soldier, aggressively depicting the raining as harsh and suicidal. Directed in 1979, Steven Kubrick’s position on war was neither affirmative nor negative and simply stated he was concerned with â€Å"the way things are†, thus forcefully depicting the disciplinary discrepancies of the Americans in Vietna m. The opening montage of the camera focused on the soldier’s heads being shaved depicts the blank expressionless faces of the soldiers and shows the identity loss of the soldiers in war, illustrating their inconsequential individuality. Kubrick uses harsh and explicit dialogue to stress how even though war is â€Å"fair† everyone participating is â€Å"equally worthless†, again punishing the soldiers for their racial background and individuality. Likewise, in the final scene of the introductory sequence before the war, Kubrick displays the suicidal aspect of the meaningless punishment, where Private Pile† explains that even though there is war going on in Vietnam, he is in a â€Å"world of shit† after the punishment from the senior officers. This harsh portrayal of pre-war training explains Kubrick’s view that internally war can be as detrimental as it is on the battlefield. Correspondingly, Owen aims to eradicate all romantic feelings in â€Å"Dulce et Decorum Est† and instead represent war as a sinful and devilish practice. The ironic titling of the poem initially subverts any sense of patriotism and glory associated with war, and condemns the romanticised portrayals of war that the government and the media have created. By deliberately subverting the heroic Latin phrase through the bleak ideas in his poem, Owen depicts the title as an â€Å"old lie† where he suggests that glorification and bravery in war is undermined by the fallacies of the government and the media. In addition, his use of metaphor in the first stanza exemplifies the mechanised and fatigued state of the soldiers in war, where the soldiers â€Å"marched asleep† from the endless punishment and futility of war. Owen indicates here exactly how â€Å"lame† the soldiers were with the pain and suffering of war, illuminating the punishment and empty nationalism he attempts to portray. Furthermore, the graphic imagery of the sinfulness and devilish nature of war used in the third stanza highlights the devilish and sinful representation, by comparing a comrade to a â€Å"devil sick of sin†. Owen here evaluates war as a whole, as a place where even the devil can no longer handle the horrid pain and meaningless suffering. This powerful imagery removes the Romantic ideals of patriotism substituting them with a morbid depiction of â€Å"choking† with sin. Thus, Owen eradicates the glory and valour that had been associated with war literature in the 20th Century and indicts war as a fallacy to children who are â€Å"desperate† for honour. Ultimately, Owen aims to challenge all feelings of glory and heroism that are commonly associated with war and shift these concepts to a historic fallacy where sinful and devilish behaviour arises. Alternately, Kubrick strives to explore both the harsh and unforgiving nature of the battlefield and the meaningless punishment experienced internally in the U. S Marine Corps, where even the pre-war training results in the suicide of a soldier. Each text explains the horror and meaningless punishment as a constant and predictable outcome, as wells as the horrifying and sinful behaviour that soldiers experience, however Owen’s poem â€Å"Dulce et Decorum Est† more effectively depicts the unpredictability of war by emphasising how disgusting war is, promoting it as foreign to any kind of valour and partisanship.

As we are speaking about the functions of all this words in different situations we have to define â€Å"functional style† Under a â€Å"function style† we understand language means peculiar to a specific sphear of communication.

Swag has different meanings throughout the world.In Australia the term swag is used to refer to the dangling luggage that a homeless man carries. Swag is also used to describe home items such as swag lamps and swag curtains, which are basically dangling versions of the original lamp and curtains (Snoops). In America, many relate the word swag to swarm which describes a certain motion of a bold, arrogant, and conceited person. So I think based on this information its easy to say that the word swag was introduced through old hip-hop, where loose clothing and sagging was the fashion and now has evolved through modern hip-hop to accommodate the newer fashion.The most common misconception about the word swag is that its often misunderstood as an acronym. Many people think that swag Is an acronym for Secretly We Are Gay. The exact origin of the word swag Is soul a mystery. Some believe the first written usage of the word swag was first written by a Gilbert Monk named Robert Manning in 1303. Manning in his poem says there was a yecch, and made a baggage, A bell of leper, a greet sewage. In this poem Manning refers to sewage as a bag. According to Oxford dictionary, swag is a verb derives from the Scandinavian word SVGA which means to rock unsteadily or lurch.This Idea Is widely accepted due to the fact that swag sounds Like It originated from the word swagger, which also means to sway. The word Is said to have entered the English language around the 13th century meaning hanging loosely (Snoops). Other meanings of swag also include a sinkhole used to collect water, a shop that sold stolen goods, or stolen loots by either pirates or criminals. Some also say that swag was used in old English movies to describe criminal loots, leading to false accusations of acronyms such as Stolen Without A Gun, Sold Without A Guarantee, and Souvenirs Warblers And Gifts.Based on this Its easy to connect swag to older or correct usage of the word swag is hard to define Just because its a slang word and there is no exact definition. According to our culture and society, I would say swag is a term used to describe a persons clothing and a part of his personality. Its easy to infer a persons personality by looking at his clothing. Different people have different personalities and some of it is shown through their dressing. This freedom of expression can show a persons values, beliefs, and culture. So, in a sense a persons swag can portray his character. Swag usually has a negative connotation due to the over usage of the word in the rap industry, but in my opinion swag is a general term that can be used by anyone. Just like the words Boom, Whack, Slop, and Kabob, swag can be used at the end of a sentence to add emphasis and humor. In conclusion, swag is an old word that has its own history but has evolved through human influence to have a completely different meaning throughout different parts of the world. Even though the overuse of the word has completely dried its value, swag still has an interesting origin and is fun to use.

Projectile Motion free essay sample

A pool ball leaves a 0. 60-meter high table with an initial horizontal velocity of 2. 4 m/s. Predict the time required for the pool ball to fall to the ground and the horizontal distance between the tables edge and the balls landing location. b. A soccer ball is kicked horizontally off a 22. 0-meter high hill and lands a distance of 35. 0 meters from the edge of the hill. Determine the initial horizontal velocity of the soccer ball. Problem Type 2: A projectile is launched at an angle to the horizontal and rises upwards to a peak while moving horizontally. Upon reaching the peak, the projectile falls with a motion that is symmetrical to its path upwards to the peak. Predictable unknowns include the time of flight, the horizontal range, and the height of the projectile when it is at its peak. Examples of this type of problem are a. A football is kicked with an initial velocity of 25 m/s at an angle of 45-degrees with the horizontal.

A long jumper leaves the ground with an initial velocity of 12 m/s at an angle of 28-degrees above the horizontal. Determine the time of flight, the horizontal distance, and the peak height of the long-jumper. The second problem type will be the subject of  the next part of Lesson 2. In this part of Lesson 2, we will focus on the first type of problem sometimes referred to as horizontally launched projectile problems. Three common kinematic equations that will be used for both type of problems include the following: Equations for the Horizontal Motion of a Projectile The above equations work well for motion in one-dimension, but a projectile is usually moving in two dimensions both horizontally and vertically. Since these two components of motion are independent of each other, two distinctly separate sets of equations are needed one for the projectiles horizontal motion and one for its vertical motion. Thus, the three equations above are transformed into two sets of three equations. For the horizontal components of motion, the equations are Of these three equations, the top equation is the most commonly used. An application of projectile concepts to each of these equations would also lead one to conclude that any term with ax  in it would cancel out of the equation  since ax= 0 m/s/s. Equations for the Vertical Motion of a Projectile For the vertical components of motion, the three equations are In each of the above equations,  the vertical acceleration of a projectile is known to be -9. 8 m/s/s  (the acceleration of gravity). Furthermore, for the special case of  the first type of problem  (horizontally launched projectile problems), viy  = 0 m/s. Thus, any term with viy  in it will cancel out of the equation. The two sets of three equations above are the kinematic equations that will be used to solve projectile motion problems. Solving Projectile Problems To illustrate the usefulness of the above equations in making predictions about the motion of a projectile, consider the solution to the following problem. ExampleA pool ball leaves a 0. 60-meter high table with an initial horizontal velocity of 2. 4 m/s. Predict the time required for the pool ball to fall to the ground and the horizontal distance between the tables edge and the balls landing location. | The solution of this problem begins by equating the known or given values with the symbols of the kinematic equations x, y, vix, viy, ax, ay, and t. Because horizontal and vertical information is used separately, it is a wise idea to organized the given information in two columns one column for horizontal information and one column for vertical information. In this case, the following information is either given or implied in the problem statement: Horizontal Information| Vertical Information| x = vix  = 2. 4 m/sax  = 0 m/s/s| y = -0. 60 mviy  = 0 m/say  = -9. 8 m/s/s| As indicated in the table, the unknown quantity is the horizontal displacement (and the time of flight) of the pool ball. The solution of the problem now requires the selection of an appropriate strategy for using the  kinematic equationsand the known information to solve for the unknown quantities. It will almost always be the case that such a strategy demands that one of the  vertical equations  be used to determine the time of flight of the projectile and then one of the  horizontal equations  be used to find the other unknown quantities (or vice versa first use the horizontal and then the vertical equation). An organized listing of known quantities (as in the table above) provides cues for the selection of the strategy. For example, the table above reveals that there are three quantities known about the vertical motion of the pool ball. Since each equation has four variables in it, knowledge of three of the variables allows one to calculate a fourth variable. Thus, it would be reasonable that a vertical equation is used with the vertical values to determine time and then the horizontal equations be used to determine the horizontal displacement (x). The  first vertical equation  (y = viy†¢t +0. 5†¢ay†¢t2) will allow for the determination of the time. Once the appropriate equation has been selected, the physics problem becomes transformed into an algebra problem. By substitution of known values, the equation takes the form of -0. 60 m = (0 m/s)†¢t  + 0. 5†¢(-9. 8 m/s/s)†¢t2 Since the first term on the right side of the equation reduces to 0, the equation can be simplified to -0. 60 m = (-4. 9 m/s/s)†¢t2 If both sides of the equation are divided by -5. 0 m/s/s, the equation becomes 0. 122 s2  =  t2 By taking the square root of both sides of the equation, the time of flight can then be determined. = 0. 350 s  (rounded from 0. 3499 s) Once the time has been determined, a  horizontal equation  can be used to determine the horizontal displacement of the pool ball. Recall from the  given information, vix  = 2. 4 m/s and ax  = 0 m/s/s. The first horizontal equation (x = vix†¢t + 0. 5†¢ax†¢t2) can then be used to solve for x. With the equation selected, the physics problem once more becomes transformed into an algebra problem. By substitution of known values, the equation takes the form of x = (2. 4 m/s)†¢(0. 3499 s) + 0. 5†¢(0 m/s/s)†¢(0. 499 s)2 Since the second term on the right side of the equation reduces to 0, the equation can then be simplified to x = (2. 4 m/s)†¢(0. 3499 s) Thus, x = 0. 84 m  (rounded from 0. 8398 m) The answer to  the stated problem  is that the pool ball is in the air for 0. 35 seconds and lands a horizontal distance of 0. 84 m from the edge of the pool table. The following procedure summarizes the above problem-solving approach. a. Carefully read the problem and list known and unknown information in terms of the symbols of the kinematic equations. For convenience sake, make a table with horizontal information on one side and vertical information on the other side. b. Identify the unknown quantity that the problem requests you to solve for. c. Select either a horizontal or vertical equation to solve for the time of flight of the projectile. d. With the time determined, use one of the other equations to solve for the unknown. (Usually, if a horizontal equation is used to solve for time, then a vertical equation can be used to solve for the final unknown quantity. ) One caution is in order. The sole reliance upon 4- and 5-step procedures to solve physics problems is always a dangerous approach. Physics problems are usually just that problems! While problems can often be simplified by the use of short procedures as the one above, not all problems can be solved with the above procedure. While steps 1 and 2 above are critical to your success in solving horizontally launched projectile problems, there will always be a problem that doesnt  fit the mold. Problem solving is not like cooking; it is not a mere matter of following a recipe.

Chemistry Major College Courses

Chemistry Major College Courses Are you interested in studying chemistry in college? Here is a look at the courses you can expect to take if you have a chemistry major. The specific courses you take will depend on which school you attend, but in general you can expect a heavy emphasis on chemistry and math. Almost all of the chemistry courses include a lab component, too. General ChemistryOrganic ChemistryInorganic ChemistryBiochemistryAnalytical ChemistryPhysical ChemistryPhysicsBiologyCalculusProbabilityStatistics Computer Science Sequence of Courses Some of the required classes can be taken whenever you can fit them into your schedule, such as probability, statistics, and computer science. Others have prerequisites. What this means is that you have to take one or more other classes before youll be allowed to enroll. If possible, a chemistry major should try to take general chemistry as a freshman. The course is typically broken up into two parts and takes an entire academic year to complete. Taking it early helps a student determine whether chemistry is truly what they want to pursue and it opens the opportunity to take organic chemistry. Organic chemistry also requires an entire academic year to complete at most institutions. It is a prerequisite for biochemistry and other interdisciplinary courses. In other words, a student usually needs three years to get through the general chemistry, organic chemistry, and biochemistry sequence. If youre a chemistry major and you wait until your junior (third) year to take general chemistry, you cant graduate in less than four and a half years! In addition to organic chemistry, general biology is a prerequisite for biochemistry. General biology lasts an entire academic year. A student should be careful when registering for general biology to make certain its the correct class. Many schools offer a watered down version of general biology for non-science majors that may count for college credit, but wont satisfy the requirements for a major or to take higher level biology or chemistry courses. Physics and sometimes calculus are required to take physical chemistry. Because physics is often taken in the second or third year, its normal for physical chemistry to be one of the last major courses a chemistry major takes. Inorganic chemistry always requires general chemistry. Some schools tack on additional requirements. Like physical chemistry, its typically taken later in a students academic career.
