Direct Exchange Geothermal Heat Pump Essay Example

Direct Exchange Geothermal Heat Pump Essay Example Direct Exchange Geothermal Heat Pump Essay Direct Exchange Geothermal Heat Pump Essay Direct exchange Direct exchange geothermal heat pump The Direct exchange geothermal heat pump is the oldest type of geothermal heat pump technology. It is also the simplest and easiest to understand. The ground-coupling is achieved through a single loop circulating refrigerant in direct thermal contact with the ground (as opposed to a combination of a refrigerant loop and a water loop). The refrigerant leaves the heat pump appliance cabinet, circulates through a loop of copper tube buried underground, and exchanges heat with the ground before returning to the pump. The name direct exchange refers to heat transfer between the refrigerant and the ground without the use of an intermediate fluid. There is no direct interaction between the fluid and the earth; only heat transfer through the pipe wall. Direct exchange heat pumps are not to be confused with water-source heat pumps or water loop heat pumps since there is no water in the ground loop. ASHRAE defines the term ground-coupled heat pump to encompass closed loop and direct exchange systems, while excluding open loops. Direct exchange systems are significantly more efficient and have potentially lower installation costs than closed loop water systems. Coppers high thermal conductivity contributes to the higher efficiency of the system, but heat flow is predominantly limited by the thermal conductivity of the ground, not the pipe. The main reasons for the higher efficiency are the elimination of the water pump (which uses electricity), the elimination of the water heat exchanger (which is a source of heat losses), and most importantly, the latent heat phase change of the refrigerant in the ground itself. While they require much more refrigerant and their tubing is more expensive per foot, a direct exchange loop is shorter than a closed water loop for a given capacity. A direct exchange system requires only 15 to 30% of the length of tubing and half the diameter of drilled holes, and the drilling or excavation costs are therefore lower. Refrigerant loops are less tolerant of leaks than water loops because gas can leak out through smaller imperfections. This dictates the use of brazed copper tubing, even though the pressures are similar to water loops. The copper loop must be protected from corrosion in acidic soil through the use of a sacrificial anode or cathodic protection.

What to Do When Words Appear Twice in a Row

What to Do When Words Appear Twice in a Row What to Do When Words Appear Twice in a Row What to Do When Words Appear Twice in a Row By Mark Nichol Using a word twice in a row isn’t always a no-no, but there’s always a more elegant way to revise a sentence in which you might initially be inclined to repeat a word immediately. When words collide, try these approaches: 1. â€Å"What you do do is your own business.† Even if this sentence is intended as a counterpoint to a â€Å"what you don’t do† proposition, the emphatic first do is superfluous (â€Å"What you do is your own business†). If you must retain the repetition, introduce a separating phrase: â€Å"What you do decide to do is your own business.† 2. â€Å"They had had many arguments.† Replace the second had with a prepositional phrase (â€Å"They had gotten into many arguments†) or a more specific verb (â€Å"They had endured many arguments†), or introduce more vivid imagery into a revision (â€Å"They had verbally sparred many times†). 3. â€Å"I showed her her message.† Replace one pronoun preferably, both of the pronouns with a noun (â€Å"I showed my sister the woman’s message†). This isn’t a problem with him, because two forms of the pronoun would appear (â€Å"I showed him his message†), though, again, if him and his refer to different men, it might be better to specify, in place of one pronoun or the other, one of the men in question. 4. â€Å"He came in in disarray.† Replace the prepositional phrase with a simple verb (â€Å"She entered in disarray†). 5. â€Å"She gives in in every case.† Simply recast the final phrase (â€Å"She gives in every time†) or flip the phrase to the front (â€Å"In every case, she gives in†). 6. â€Å"What it is is a travesty.† â€Å"What it is† is always an unnecessarily verbose way to start a sentence. Start with the subject (â€Å"It’s a travesty†). 7. â€Å"I placed the card I had written on on the desk.† Recast the prepositional phrase â€Å"written on† with on at its head (â€Å"I placed the card on which I had written the note on the desk†). But first confirm that the modifying phrase involving written is necessary at all. 8. â€Å"We realize that that will not be satisfactory.† Replace the second that with a noun (â€Å"We realize that the proposal will not be satisfactory†). 9. â€Å"We will discuss this this evening.† Replace the first this with a pronoun (â€Å"We will discuss it this evening†) or a noun (â€Å"We will discuss the matter this evening†). 10. â€Å"Is there someone I can talk to to resolve the issue?† Employ a participial phrase in place in the infinitive phrase â€Å"to resolve† (â€Å"Is there someone I can talk to about resolving the issue?†) or amplify the second to by replacing it with the phrase â€Å"in order to† (â€Å"Is there someone I can talk to in order to resolve the issue?†). Occasionally, an immediate repetition of a word, separated from the first instance by punctuation, is appropriate for emphatic effect (â€Å"I have come here from far, far away†). At other times, even though punctuation separates the repetition, a recast would improve the sentence. For example, â€Å"Even though I was there, there didn’t seem to be anything for me to do† might be revised to â€Å"Even though I was there, I didn’t seem to be of any use† or â€Å"Despite my presence, there didn’t seem to be anything for me to do.† Want to improve your English in five minutes a day?

Information Technology- Security Research Paper Example | Topics and Well Written Essays - 500 words

Information Technology- Security - Research Paper Example United States, records concerning the use of information indicate that the concept has been fundamental when building the required trust and reliability of the information for consumers. Consequently, the concept has enhanced the availability, integrity, authenticity, confidentiality, and non- repudiation of information as discussed in this piece. An organization defines its information assurance policy as a course of actions pursued to enable organizations to obtain information assurance security. As such, the organizations formulate policies that describe appropriate behaviour concerning the use of information. In the contemporary society, the equipments and processes needed to meet the security requirements assist in the formulation of policies that govern the use of data in research (Herold & Rogers, 2011). Consequently, information assurance limits the risks that the misuses of information pose to organizations. Information assurance policies prioritize information based on the capacity of an organization to disseminate risks. Lastly, the policies concerning the use of information enhance privacy in organizations. The international Facility management association defines facility management as a profession encompassing multiple disciplines that enhances the functionality of the built environment. According ICISA & Park (2009), information assurance helps in making changes to the functional areas of an organization. Customer relation, time management, business continuity and financial awareness are some of the activities that are prone to information insecurities. Therefore, organizations need to monitor their security in order to function effectively. The management should also regulate the transmission of information in its physical form. This guarantees safe storage and usage of information. According to ICISA & Park (2009), quick response to threats changes reduces risks such as obsolescence and misuse of information. Information assurance entails

Timeline of Geometry Essay Example for Free

Timeline of Geometry Essay It is believed that geometry first came to being when and Egyptian Pharaoh wanted to tax farmers who raised crops near the Nile River. To do that the pharaoh’s agents had to measure the amount of land that was being used. 1. 2900 BC – The first pyramid was constructed. The knowledge of geometry was important due to the fact it consisted a square base and triangular faces. 2. 2000 BC- It was the earliest record of calculating the area of a triangle, however there is no tangible evidence. 3. 624-547 BC- The Thales of Miletus was said to be the person to bring the science of geometry from Egypt to Greece. He created the Thales’ Theorem. 4. 569-475 BC- The next great geometer was Pythagoras. He had created the Pythagorean Theorem that states in a right triangle the sum of sides A and B are equivalent to side C. 5. 400-355 BC- Eudoxus of Cnidus was the one who discovered the Theory of Proportions. Where in there are methods to find the area and volumes of figures with curves and many other things. 6. 382-283 BC- Euclid of Alexandra who is also known as â€Å"The father of Geometry† created a book called â€Å"The elements†. This book was the main textbook to teach math (mainly geometry). 7. 287-212 BC- Archimedes of Syracuse was the inventor of many mechanical devices such as the screw, the pulley and the lever. He discovered the measurement of a circle and his wrote a book â€Å"On the Sphere and the Cylinder† in which he showed the volumes and surface areas of spheres and cylinders. 8. 1596-1650 – Rene Descartes wrote the famous book â€Å"Discourse on the Method of Rightly Conducting the Reason in the Search for Truth in the Sciences. He created analytic geometry in which the geometric figure is placed into a coordinate system to show evidence and to obtain information using algebraic equations. 9. 1777-1855- Carl Friedrich Gauss with Archimedes and Newton invented non-Euclidian geometry prior to the work of Janos Bolyai and Nikolai Lobachevsky. Non-Euclidian geometry refers to any geometry that is not based in anything that predicates through Euclid. 10. 1982- The most recent development in geometry is fractal geometry. It was created by Benoit Mandelbrot in his book called â€Å"The Fractal Geometry of Nature†. Where it states that a fractal is a geometric shape that is self-similar and has fractional dimensions.

The Necklace Essay -- Literary Analysis, Guy de Maupassant

â€Å"The Necklace† Around the world, values are expressed differently. Some people think that life is about the little things that make them happy. Others feel the opposite way and that expenses are the way to live. In Guy de Maupassant’s short story, â€Å"The Necklace†, he develops a character, Madame Loisel, who illustrates her different style of assessments. Madame Loisel, a beautiful woman, lives in a wonderful home with all the necessary supplies needed to live. However, she is very unhappy with her life. She feels she deserves a much more expensive and materialistic life than what she has. After pitying herself for not being the richest of her friends, she goes out and borrows a beautiful necklace from an ally. But as she misplaces the closest thing she has to the life she dreams of and not telling her friend about the mishap, she could have set herself aside from ten years of work. Through many literary devices, de Maupassant sends a message to value less substance arti cles so life can be spent wisely. â€Å"The Necklace† ends up to be a very ironic story as it explains why valuing the more important things in life can be very effective towards a person’s happiness. One example of the story’s irony is when she is at the party dressed as a beautiful and fancy woman. ‘She danced madly, wildly, drunk with pleasure, giving no thought to anything in the triumph of her beauty, the pride of her success†¦Ã¢â‚¬â„¢ (pg 193). This is a form of dramatic irony because Guy explains earlier that Mme. Loisel is just a middle class woman who dreams of a wealthy life, but she is just alluding herself as a luxurious woman. Another example of irony in the story is when Madame found out that the necklace was paste. On page 196, Mme. Forestier, Ma... ...ches and expenses. The message to value more important things in order to have a wisely spent life is demonstrated very well through literary devices in â€Å"The Necklace†, by Guy de Maupassant. Madame undergoes an ironic moment in life as she learns what is worth valuing. She is a very greedy woman who only cares about herself. The reader would never think of her as the person to do work, but that thought changes as she misplaces what she thinks of as a valuable item. If Madame just learned how to live life in a way that will not make her upset and to value things that are valuable towards life instead of expenses, she will be better off. But this is how Madame views her life, while others take notice of the significance in their lives. Values are different towards people across the world, and Guy de Maupassant defines that in his short story, â€Å"The Necklace†.

Character Analysis of Sylvia from “A White Heron” Essay

â€Å"There never was such a child for straying about out-of-doors since the world was made† (Jewett 69). A young girl, Sylvia, lived in a city environment for the first eight years of her life. Then, Sylvia came to live with her grandmother in the country, where the little girl came alive and became one with nature. One day in her travels through the countryside with her cow she encounter a lost ornithologist who was in search of a white heron that he had spotted in the area weeks before. At first, the little girl was frightened of this man who carried and gun and killed the creatures that he cared so deeply about. She could not understand why this man would do such a thing. However, as they spent time together, Sylvia found this man most charming and delightful. In the short story, â€Å"A White Heron,† by Sarah Orne Jewett, a young country girl’s innocence is lost when her heart is torn between her love for a young bird collector and her love for nature. Sylvia is isolated while living at the farmhouse; her only companion is a cow. Sylvia may be lonely, but she is not lonesome. She is much happier and lively here than in the crowded industrial town. At the farm, she spends all day outside and lives in unity with the environment that surrounds her. â€Å"They key to her vivacity is that she is utterly in harmony with nature† (Held 171). When the ornithologist aggressively whistles in her territory her equilibrium is upset. The man explains to the horror-stricken girl that he got lost while in pursuit of the white heron. â€Å"Thus when Jewett first introduces the ornithologist himself, she labels him â€Å"the enemy† (171). There seems to be something threatening in his very â€Å"boyness† that makes Sylvia fearful. Her awe of the ornithologist may in part be caused by his being the first grow-up boy she has seen in her woodland isolation† (171). The hunter attempts to induce Sylvia to lead him to the wanted bird by offering her a reward of ten dollars. â€Å"Despite his attractive qualities, there is something insidious about his attempt to bribe the girl in effect to betray her world. He suggests a sort of blithe Satan tempting a naà ¯ve Eve to eat of the fruit Tree of Knowledge† (171). When she thinks about how poor she is, her mind wanders off after the â€Å"treasures† that his money could buy. This introduction of money into Sylvia’s simplicity disrupted her sense of loyalty to nature. However, as they spent time together, Sylvia found this man most appealing. Her virgin heart that lied dormant, vigorously awakened, as the innocent child was overwhelmed with an emotion of love towards this mysterious man. â€Å"Sylvia still watched the young man with loving admiration. She had never seen anybody so charming and delightful; the woman’s heart, asleep in the child, was vaguely thrilled by a dream of love.† This does not surprise me though, it is common for young girls to have a crush on or become attracted to a charming older man who impresses them. Sylvia knew where the sportsman could find this precious bird he was in search of. Sylvia and the man are true to the gender roles society has bestowed upon them while traveling through the dense woodlands. The female instinct inside her would not allow her to lead the guest to the heron’s nest, nor be the first to start up a conversation with the guest. Instead, she kept silent observing all around her, watching his every move, and concentrating on every word spoken from his lips. â€Å"She grieved because the longed-for white heron was elusive, but she did not lead the guest, she only followed, and there was no such thing as speaking first.† â€Å"Her socialization, ironically, saves her from revealing the bird and therefore betraying her world to this intruder†(172). The day outing with the bird collector brings Sylvia closer to him, and distances her from the natural world. She could get no sleep that night, and ventured out into the forest. She climbed, and climbed the huge oak tree in search of the heron’s nest. â€Å"Once she is aloft in the pine tree, â€Å"the sharp dry twigs caught and held her and scratched her like angry talons, the pitch made her little fingers clumsy and stiff,† as though nature itself sought to keep her from succeeding in her project and thereby breaching their heart-to-heart relationship† (173). Then came the light as she neared the treetop, and a sea of sky appeared to her over the entire countryside. Only then was the heron’s exact location of the heron’s nest showed to her. She had discovered the bird’s hiding place among the green marsh. When she sees the beautiful bird, she comes back to reality and realizes the superficiality of the man. She recognizes that the  man has come between her and nature. â€Å"In this instant Sylvia balances the desire to earn the ten dollars and to please the attractive stranger against her unspoken fidelity to nature† (173). She knew that the man was well worth making happy, and after all he promised them a nice some of money, so she would also be happy. No, Sylvia could not do it. She would not give the birds life away. The girl and bird had united that morning in the golden sea, and this forbid her to speak. Her heart had developed into that of a strong feminist who could not be swayed by the charm of a man. She gave her love and devotion to the natural world that would always be there for her. In the story, â€Å"A White Heron† the heron, Sylvia, is tempted by â€Å"evil† represented by the sportsman to betray her natural self. The story emphasizes the eternal struggle between the forces of good and evil, and the continual seduction of good by evil. The story concludes that all â€Å"woodland and summertime secrets are like the heron’s safe. For in the end the heron’s life has become the equivalent of the girl’s life, at least of her existence heart to heart with nature† (174). The story implies that in a sense Sylvia is the heron, untouched and at peace with the surrounding environment. However due to external forces, the hunter in this case, the virgin Sylvia endures a loss of innocence. If Sylvia surrendered the heron it would be the equivalence of giving up a part of her and what she stands for. The heron and Sylvia depend on each other for survival. It was impossible for her to abandon her integrity and allegiance to nature or else she would no longer be Sylvia. Sylvia was able to resist the appeal of man, money, and attention. Sylvia displayed her growth as a woman by staying committed to her strong sense of values, and strengthening her heart to heart relationship with nature. Works Cited Bogard, C.R., and J.Z.

Juvenile Crime Paper Essay

In the juvenile justice system believes in giving a juvenile a second chance, and protects their privacy. They also want to make sure they receive treatment and support services rather than just punishment. The juvenile system focuses more on their needs, and those goals are met with treatment and rehabilitation so they won’t become repeat offenders. After a juvenile completes their program their records can be sealed or destroyed once they reach 18. The juvenile system status in question is to determine delinquency, whether an act of was violated or not. The system also wants to make sure the best interest of the child is taken into consideration, regardless if they are guilty or innocent. For the most part when a child is in custody and pending the hearing, they may be released into the custody of a parent or guardian. Juveniles have closed hearings instead of a trial. The right to a jury does not exist. A juvenile is not arrested; they are taken into custody from an order b y the judge or complaint. Usually juveniles are only incarcerated with other youth offenders and in juvenile facilities. In the adult court system the status question for adults is to determine guilt or innocence. The goal for adult proceedings is to determine offender’s guilt or innocence. Pending a trial, an adult can be released through bail, or on their own recognizance. Adult trials are open to the public, and they also have a right to a jury trial. The trial could last months, and the trial determines guilty or innocence. Adults are housed with other adult offenders in jail or prison facilities. Adults also have rights to appeal their sentence. Delinquency is the broadest usage, juvenile actions or conduct in violation of criminal law, juvenile status offenses, and other juvenile misbehavior. When my son was a juvenile and got into trouble his crimes made us appear in front of a judge who decided he was a delinquent, and he would remain in their custody until he completed  some of the programs that were assigned to him. At the time I did not understand much about the juvenile court system. That is why this class and course is so important to me. If only I knew then what I know now about the justice system it would have changed the way I handled certain situations that had to do with my son. Status offense is an act or conduct that is declared by statue to be an offense, but only when committed by or engaged in by a juvenile, ad that can be adjudicated only by a juvenile court. Oklahoma County Juvenile Justice Center in Oklahoma County has developed a Community Outreach Prevention Program to assist the community and schools on the topics of Bullies and Weapons. The program want to bring awareness to the community and schools about the effects of Bullies and Weapons. The staff consists of employees from the Juvenile Bureau who work with youth in the Detention Center and in Probation Services. The presentations are age, and audience appropriate. The Mission of the Juvenile Bureau is â€Å"To Work with the community to Prevent and Control Juvenile Delinquency.† The Juvenile Court Era was a time when children’s needs were recognized, and it led to legislation requiring juveniles to have separate hearings than adults. Later it was also thought juveniles should not have contact with adult offenders. Soon this became the model for juvenile court status throughout other states. A juvenile court was created and they applied the word delinquent instead of using criminal to juvenile offenders. The judges were expected to serve as advocates for juveniles while guiding their development. In 1938, the federal government passed the Juvenile Court Act, which embodied many of the features of the Illinois statue. By 1945, every state had enacted special legislation focusing on the handling of juveniles, and the juvenile court movement became well established. There were five philosophical principles that were summarized. (Schmalleger, 2011). 1. The state is the parent of the children. 2. The children are worth saving without harsh treatment. 3. Children should be nurtured 4. Their goal plan should be individualized just for them. 5. Noncriminal procedure are necessary to give primary consideration to the needs of the child. There are several categories of Children in the Juvenile Justice System. Theses categories are still used today in most  jurisdictions to describe the variety of children subject to juvenile court jurisdiction. 1. Delinquent children are those who have broken the criminal law. 2. Undisciplined children would be when the child is out of control. 3. Dependent children usually have no one to care for them like a parent. 4. Neglected children are those who do not receive proper care from their parents. 5. Abused children are those that suffer abuse from the very person that is suppose to be taking care of them. 6. Status offender embraces children who violate laws written only for them. I want to talk about the Homicide rate among juveniles. According to the FBI’s Supplementary Homicide Report: 1980-2010, and it provides access to more than twenty years of national and state data on h omicide victims and known homicide offenders. Until I completed some research on juvenile crime I had not realized how much crimes were committed by our youth. This has been going on for a very long time, and I don’t think people realize the impact of crime on youth today. These statistics were really heart breaking. I am really glad I chose to get a degree in this field, because in some way I would love to make a difference. With statistics like this It makes me wonder why we have so many juvenile offenders that continue to commit crimes after they have reached adulthood. I do not believe that juveniles should be housed with adult offenders. I believe our youth still have a chance at life, and they should not be blinded by a corrupt repeat offender adult. I think if given the chance adults would try to take advantage of a child to the point of rape, bribery, joining gangs, committing more crimes, and become career criminals. I would say our children are our future, and not giving up on them is the key to success. When a juvenile gets into trouble some people are so quick to just write them off. Having juveniles incarcerated with adults is like throwing them to the wolves whatever could happen usually does happen. Adults that have been incarcerated for some time prey on new young fish. They are looking for someone to keep them satisfied by any means necessary. In order for our youth to become productive individuals in society we have to provide the education and the tools that are needed. When a juvenile commit a crime we should first look at why the crime was committed, was it due to neglect, abuse, or something like that. Then when we figure out what the problem is rehabilitation can be created to reform the juvenile offender, and provide the necessary skills to help them in the future. When juveniles are given a sentence, and they have to be incarcerated for an extended period of time they lose contact with family members and friends. Some parents try to be there for their children however they leave them in there to do for themselves. Some parents feel that will teach the juvenile a lesson about getting into trouble.

Acid Base Science Fair Project Ideas

Acid Base Science Fair Project Ideas Are you looking for a science fair idea involving acids, bases, or pH? Here are some ideas to get you started: Measure the amount of vitamin C (ascorbic acid) in orange juice (or another juice). Test to see how the amount of vitamin C changes after the juice is exposed to air (or light or heat).Simulate acid rain by adding an acid to water. You can use pH paper to test whether the acidity is changed after water runs through different types of soil or through plant root systems.Is the acidity of apples (malic acid) affected by their ripeness?See if you can make your own pH indicator from common plants or chemicals.Measure the pH of common acidic beverages (soft drinks, lemonade, orange juice, tomato juice, milk, etc.) and examine how easily they corrode metal (such as iron). Another idea: which is more corrosive? A salt solution or an acidic liquid?Do all brands of orange juice contain the same amount of ascorbic acid?Compare the effects of different acidic fruit juices and liquids (e.g., vinegar) at preventing apple browning.Which animals saliva has the lowest pH? You could test humans, dogs, cats, possibly other species. What is the effect of pH on growth or survivability of daphnia (an aquatic crustacean)? You could test other factors too, such as salinity or the presence of detergent in the water.How does the pH of the water affect tadpole development?Does acid rain (real or simulated) affect the number and type of organelles seen in algae under the microscope?Which is a better conductor of electricity, an acid or a base?Does the pH of water affect the growth or survivability of mosquito larvae?

General James Wolfe in the French and Indian War

General James Wolfe in the French and Indian War Major General James Wolfe was one of Britains most famous commanders during the French and Indian/Seven Years War (1754-1763). Entering the army at a young age, he distinguished himself during the War of the Austrian Succession (1740-1748) as well as aided in putting down the Jacobite Rising in Scotland. With the beginning of the Seven Years War, Wolfe initially served in Europe before being dispatched to North America in 1758. Serving under Major General Jeffery Amherst, Wolfe played a key role in the capture of the French fortress at Louisbourg and then received command of the army tasked with taking Quebec. Arriving before the city in 1759, Wolfe was killed in the fighting as his men defeated the French and captured the city. Early Life James Peter Wolfe was born January 2, 1727, at Westerham, Kent. The eldest son of Colonel Edward Wolfe and Henriette Thompson, he was raised locally until the family moved to Greenwich in 1738. From a moderately distinguished family, Wolfes uncle Edward held a seat in Parliament while his other uncle, Walter, served as an officer in the British Army. In 1740, at the age of thirteen, Wolfe entered the military and joined his fathers 1st Regiment of Marines as a volunteer. The following year, with Britain fighting Spain in the War of Jenkins Ear, he was prevented from joining his father on Admiral Edward Vernons expedition against Cartagena due to illness. This proved to be a blessing as the attack was a failure with many of the British troops succumbing to disease during the three-month campaign. The conflict with Spain soon became absorbed into the War of the Austrian Succession. War of the Austrian Succession In 1741, Wolfe received a commission as a second lieutenant in his fathers regiment. Early the following year, he transferred to the British Army for service in Flanders. Becoming a lieutenant in the 12th Regiment of Foot, he also served as the units adjutant as it assumed a position near Ghent. Seeing little action, he was joined in 1743 by his brother Edward. Marching east as part of George IIs Pragmatic Army, Wolfe traveled to southern Germany later that year. During the course of the campaign, the army was trapped by the French along the Main River. Engaging the French at the Battle of Dettingen, the British and their allies were able to throw back several enemy assaults and escape the trap. Highly active during the battle, the teenage Wolfe had a horse shot from under him and his actions came to the attention of the Duke of Cumberland. Promoted to captain in 1744, he was shifted to the 45th Regiment of Foot. Seeing little action that year, Wolfes unit served in Field Marshal George Wades failed campaign against Lille.  A year later, he missed the Battle of Fontenoy as his regiment was posted to garrison duty at Ghent. Departing the city shortly before its capture by the French, Wolfe received a promotion to brigade major. A short time later, his regiment was recalled to Britain to aid in defeating the Jacobite Rebellion led by Charles Edward Stuart. The Forty-Five Dubbed The Forty-Five, Jacobite forces defeated Sir John Cope at Prestonpans in September after mounting an effective Highland charge against the government lines. Victorious, the Jacobites marched south and advanced as far as Derby. Dispatched to Newcastle as part of Wades army, Wolfe served under Lieutenant General Henry Hawley during the campaign to crush the rebellion. Moving north, he took part in the defeat at Falkirk on January 17, 1746. Retreating to Edinburgh, Wolfe and the army came under the command of Cumberland later that month. Shifting north in pursuit of Stuarts army, Cumberland wintered in Aberdeen before resuming the campaign in April. Marching with the army, Wolfe took part in the decisive Battle of Culloden on April 16 which saw the Jacobite army crushed. In the wake of the victory at Culloden, he famously refused to shoot a wounded Jacobite soldier despite orders from either the Duke of Cumberland or Hawley. This act of mercy later endeared him to the Scottish troops under his command in North America. The Continent and Peace Returning to the Continent in 1747, Wolfe served under Major General Sir John Mordaunt during the campaign to defend Maastricht. Taking part in the bloody defeat at the Battle of Lauffeld, he again distinguished himself and earned an official commendation. Wounded in the fighting, he remained in the field until the Treaty of Aix-la-Chapelle ended the conflict in early 1748. Already a veteran at age twenty-one, Wolfe was promoted to major and assigned to command the 20th Regiment of Foot at Stirling. Often battling ill-health, he worked tirelessly to improve his education and in 1750 received a promotion to lieutenant colonel. In 1752, Wolfe received permission to travel and made trips to Ireland and France. During these excursions, he furthered his studies, made several important political contacts, and visited important battlefields such as the Boyne . The Seven Years' War While in France, Wolfe received an audience with Louis XV and worked to enhance his language and fencing skills. Though wishing to remain in Paris in 1754, the declining relationship between Britain and France forced his return to Scotland. With the formal beginning of the Seven Years War in 1756 (fighting began in North America two years earlier), he was promoted to colonel and ordered to Canterbury, Kent to defend against an anticipated French invasion. Shifted to Wiltshire, Wolfe continued to battle health issues leading some to believe that he was suffering from consumption. In 1757, he rejoined Mordaunt for a planned amphibious attack on Rochefort. Serving as quartermaster general for the expedition, Wolfe and the fleet sailed on September 7. Though Mordaunt captured ÃŽle dAix offshore, he proved reluctant to press on to Rochefort despite having caught the French by surprise. Advocating aggressive action, Wolfe scouted the approaches to the city and repeatedly asked for troops to execute an attack. The requests were refused and the expedition ended in failure. Louisbourg Despite the poor results at Rochefort, Wolfes actions brought him to the attention of Prime Minister William Pitt. Seeking to expand the war in the colonies, Pitt promoted several aggressive officers to high ranks with the goal of achieving decisive results. Elevating Wolfe to brigadier general, Pitt sent him to Canada to serve under Major General Jeffery Amherst. Tasked with capturing the fortress of Louisbourg on Cape Breton Island, the two men formed an effective team. In June 1758, the army moved north from Halifax, Nova Scotia with naval support provided by Admiral Edward Boscawen. On June 8, Wolfe was tasked with leading the opening landings in Gabarus Bay. Though supported by the guns of Boscawens fleet, Wolfe and his men were initially prevented from landing by French forces. Pushed east, they located a small landing area protected by large rocks. Going ashore, Wolfes men secured a small beachhead which allowed the remainder of Wolfes men to land. Having gained a foothold ashore, he played a key role in Amhersts capture of the city the following month. With Louisbourg taken, Wolfe was ordered to raid French settlements around the Gulf of St. Lawrence. Though the British had wished to attack Quebec in 1758, defeat at the Battle of Carillon on Lake Champlain and the lateness of the season prevented such a move. Returning to Britain, Wolfe was tasked by Pitt with the capture of Quebec. Given the local rank of major general, Wolfe sailed with a fleet led by Admiral Sir Charles Saunders. To Quebec Arriving off Quebec in early June 1759, Wolfe surprised the French commander, the Marquis de Montcalm, who had expected an attack from the south or west. Establishing his army on the Ile dOrlà ©ans and the south shore of the St. Lawrence at Point Levis, Wolfe began a bombardment of the city and ran ships past its batteries to reconnoiter for landing places upstream. On July 31, Wolfe attacked Montcalm at Beauport but was repulsed with heavy losses (Map). Stymied, Wolfe began to focus on landing to west of the city. While British ships raided upstream and threatened Montcalms supply lines to Montreal, the French leader was forced to disperse his army along the north shore to prevent Wolfe from crossing. Not believing that another assault at Beauport would be successful, Wolfe began planning a landing just beyond Pointe-aux-Trembles. This was canceled due to poor weather and on September 10 he informed his commanders that he intended to cross at Anse-au-Foulon. A small cove southwest of the city, the landing beach at Anse-au-Foulon required British troops to come ashore and ascend a slope and small road to reach the Plains of Abraham above. Moving forward on the night of September 12/13, British forces succeeded in landing and reaching the plains above by morning. Plains of Abraham Forming for battle, Wolfes army was confronted by French troops under Montcalm. Advancing to attack in columns, Montcalms lines were quickly shattered by British musket fire and soon began retreating. Early in the battle, Wolfe was struck in the wrist. Bandaging the injury he continued, but was soon hit in the stomach and chest. Issuing his final orders, he died on the field. As the French retreated, Montcalm was mortally wounded and died the next day. Having won a key victory in North America, Wolfes body was returned to Britain where he was interred in the family vault at St. Alfege Church, Greenwich alongside his father.

CASE5 599 Coursework Example | Topics and Well Written Essays - 1250 words

CASE5 599 - Coursework Example 133) A reinforcing loop generally develops the market value of a company along with its policy framework and a clear cut course of action. For instance in the case of a company like Whole Foods Market, the management is actively implementing the core value of satisfying and gratifying their customers with an intention to retain them. This is giving rise to a reinforcing loop. The loop starts at the core value specification, which can be diagnosed as the causal factor. The loop is processed through the organization’s customer oriented activities culminating at customer centric relationship management. The loop is then reinforced by the returning customers. This happens in consequence to the causal policy that finally results into its reiteration by the virtue of the company’s active and deployable business methods. â€Å"Balancing loops are system processes triggered to bring the system back to a preestablished norm† (Notter and Grantt, 2011, p. 133) A balancing l oop is a kind of automatic control within the organization which may bring about considerable damage if not terminated in proper time. This is a case in which a system is constrained within highly tacit parameters (Notter and Grant, 2011; Sterman, 2000). ... This oversensitivity in establishing one of the primary core values to deal with the marketing processes appears to be causing a balancing loop. The loop is executing through the unopposed policy specification and then exposing the organization to tougher competition. Figure – 1: The Reinforcement Loop formed due to Customer Centric Management Figure – 2: Setting product quality specifications with excessive stringency may lead to a negative balancing loop Part 2 Traditionally, scholars and professionals in the field of management and business research used to accept the notion of organizational learning, but its definition and theory remained unclear for a considerable period of time. However, as early as 1985, Fiol and Lyles (1985, p. 804) pointed out that â€Å"Some agreement exists that distinctions must be made between individual and organizational learning.† Consequently, it becomes an imperative to contemplate on the concept that individual learning is vit al for an organization, but organizational learning cannot be regarded as merely the sum total of each member’s erudition. An organization, unlike an individual, builds up and maintains learning mechanisms. These mechanisms influence the organization’s immediate members. Moreover, these mechanisms help in transmitting the learning outcomes to others by the means of organizational histories, paradigms, and norms. (Notter and Grant, 2011; Argyris, 1990; Fiol and Lyles, 1985) So the theory of organizational learning has emerged on the fundamentals of the earlier works regarding organizational processes and needs. In providing a summary on the most important information on organizational learning (especially at the executive level), reviewing the works of Dixon (1999) can be highly rewarding.

COMMUNICATING RISK-POST KATRINA BY PETE CALI Assignment

COMMUNICATING RISK-POST KATRINA BY PETE CALI - Assignment Example The 1978 map below shows the impact of the growth population on the sypress swamp areas are more land was reclaimed to pave way for resettlement implying that the city was barely protected from any hurricane flooding. The encroachment and growth of the population behind the hurricane protection system indicates the level of confidence the people had in the engineering projects to protect them from floods. The Katrina had devastating effects in the city of New Orleans. Firstly, ninety-five percent of homes in New Orleans East were flooded while 10,000 homes in the Greater New Orleans area were destroyed. Secondly, the Katrina destroyed vital infrastructure such as roads, sewerage, gas and water pumping stations, hospitals and public transportation. Thirdly, the Katrina destroyed approximately 160 miles of flood protection levees and floodwalls at the London Avenue Canal, the Inner Harbor Navigation Canal and the 17th Street Canal. According to Pete Cali, the Katrina caused 50 breaches in the hurricane protection system. Forty-six of these breaches were caused by overtopping that caused excessive scour at the floodwall base or levee toe and four were caused by floodwall failures due to water loads within the design conditions. Cali argues that these failures were imbedded in three engineering mistakes namely: insufficient levee height, the use of substandard soil in the construction of the levee and inadequate definition of possible failure mechanisms. Despite the devastating impact of the Katrina on the city of New Orleans, it is imperative to note that the heart of the City, especially the French Quarter, the Garden District and the Saint Charles Avenue were spared from severe damage. However, the damage can still be felt in the Ninth Ward and the New Orleans East whose water supply and sewerage system is yet to be repaired and the housing facilities are barely enough to accommodate half the pre-Katrina population. Due to the limitations in the tax revenue,
