However, today, even an infant can fully live by the virtue of advances in aeronautics, man has disproved that sky is the limit. Rockets and paceships have helped him to redefine the concept of flying. In todays world, the concept of rockets exists because of Sir Isaac Newton, a pioneer in the field of physics whose three laws of motion enabled scientists in todays date to build rockets accurately. In simple words, a rocket is a chamber enclosing a gas under pressure. A balloon is a most common example. Newtons first law states that, objects at rest will remain at rest and objects in motion will remain in motion in a straight line unless acted upon by an unbalanced force.

The force of gravity on the rocket equals with that of the pad that is holding on it. While in motion, the rocket unbalances the forces and as a result, it travels upward. Newtons second law states that, force equals mass times acceleration. The mass of the rocket changes during the flight, since the engines energy is being used up rapidly so the rocket weighs less and accelerates. The third law states that, every action has an equal and opposite reaction. As the rocket takes off and releases the gas out, the gas pushes the rocket upwards. The design of the rocket also plays an important role. To begin with, inertia, the tendency of an object to resist change while in motion is directly connected to the mass of the object. A heavier rocket will have more inertia, because it has more mass. This will in turn give the rocket more resistance. The rocket will be therefore able to surpass the wind. On the other hand, a lighter rocket will have less inertia since the mass of the rocket is less. As a result, rocket will have less resistance and the effect of the wind on the rocket will be great. Another factor that is associated with the design of the rocket is the center of the mass. The center of the object is the exact point where all of the mass of the rocket is exactly balanced. Everything is made up of matter, regardless of size, mass, or shape has a center of mass. An unstable rocket tumbles around this point. Revolving and sinking takes place around one or more of three axes: roll, pitch, and yaw. Another aspect that is lined with the design of the rocket is the center of pressure. Center of pressure is the location where all the pressure forces acting on a rocket are balanced. Center of pressure exists only when the rocket is going in the opposite direction to the wind. The center of the pressure is located near the tail and center of mass is located near the nose of the rocket. Todays rockets are an extraordinary work of human beings who have their roots in science and technology of the past. The discovery or the invention of the rocket came in existence way before Newtons Laws were ever stated. Around 400 B. C. , in southern Italy, Archytas amazed the people of the town by flying a wooden pigeon. The pigeon used steam as a propulsive gas and used the action-reaction principle, which was not stated as a law until 17th century. rocket as a weapon. They used bamboo tubes filled with gunpowder and tossed them in fire. Soon, they started experimenting and fgured out a way. They used the bamboo tube filled with gunpowder and attached it to an arrow and discovered that these gunpowder tubes could launch themselves Just by the power produced from the escaping gas. This is how they technology of rocket started. As the time passed by, Newtons theories and his three laws came into existence. His laws explained that why rockets are able to work in vacuum as well as in the outer space. Soon after that, gas laws were developed. Charles law stated that, at a onstant pressure, the volume of a fixed mass of any gas is directly proportional to its Kelvin temperature. The concept of hot balloons comes from this principle. As the balloon is heated, the volume of the balloon also increases. Since the volume is increases, the density inside the balloon also increases. The density of the air is more than the density of air that is in the balloon. This is the reason hot balloons were able to fly back in 17th century. During late 1800s and early 1900s, rockets were mainly used as a weapon to be used in the battles. William Congreve, a British Colonel designed various patterns for ockets to be used in warfare. His rockets were so successful that scientists around the around started experimenting on the rockets. William Hale, an English scientist soon came up with an excellent technique known as spin stabilization. This technique made the gases of the rocket to escape from the bottom, thus making it to spin in a bullet like fashion. Modern rocketry began in 1898, when a Russian schoolteacher named Konstantin Tsiolkovsky, proposed the idea of space exploration. It was also his suggestion of using liquid propellants in the rockets in order to achieve greater range. Since, Tsiolkovsky was the first person to suggest space exploration and the fact that he came up with other ideas and theories in the work of physics, he is known as the father of modern astronautics. Soon after the concept of propellants was introduced, an American, Robert H. Goddard started conducting practical experiments. He started working with the solid- propellant rockets. Sooner he was convinced that liquid-propellant rockets were better than the solid-propellant rockets. But at time constructing liquid-propellant rockets was much harder, since, fuel and oxygen tanks, various gas chambers and urbines were needed. After so many difficulties and hardships, Goddard was finally able to built a liquid-propellant rocket and achieved a height of 12. 5 meters. His rocket was a pioneer in the rocketry field. Due to his magnificent contributions in the field of rocketry, he is known as the father of modern rocketry. Later on, during the time of Cold war between the two superpower nations, Unites States and Soviet Union, they entered the space fght. Soviet Union was able to put a stop on America by launching the first satellite in the world called Sputnik on October 4th, 1957. After a few months, on January 31st 1958, United States launched their own satellite called Explorer l. Around that time, America organized their space program by creating NASA. It became a space agency with the intensions of exploring space for the betterment of humans. ountries. Space exploration became more advanced and rapidly increased after 1980. In 1981, Robert Crippen and John Young rotated around the Earth 36 times in a total of 54 hours. In 1983, Pioneer 10 (USA) crossed the orbit of the outermost planet, Neptune. In 1985, first satellite landed on the surface of a comet. To conclude with, in odays date, rockets are complicated structure that can go far and beyond human imaginations. The technology to build a rock et always existed, it was Just a matter of time when Archytas came up with idea. In todays date, rockets have reached a height of accuracy and this is because of Sir Isaac Newton. His laws and theories have helped the engineers to build marvelous rockets that can not only go outside the earths atmosphere but can also reach even the farthest planets that exist. Rocket Design Strategy While designing a rocket four main things are kept in mind, the nose cone, the fins, a arachute, and mass of the rocket. These four things are the building blocks of a rocket. Therefore, to achieve the maximum height possible, these things are the first ones that are kept in consideration. Nose cones can be engineered in three different shapes. They are either: parabolic, ogive or conical. They all one thing in common, they all have pointed peaks. The reason they have pointed nose is the basic physics fundamentals of aerodynamics. Parabolic shape nose cones are the best to use. The parabolic shape cone is pointy at the top and gets wider like triangle. When air ushes the rocket down, the cone shape affects the rocket the most. Since, parabolic shape advantages the rocket because all the air that strikes the rocket is slanted through the pointy peak and that pyramid shape. If the nose cone is flat it will conduct huge amount of drag or air resistance. Drag means the force of friction that is pulling the rocket downwards. To avoid this frictional force, the thrust of the engine should be more than the drag that is acting on the rocket. Nose cones are not the only thing that is important while constructing a rocket. The length of the rocket lso plays a huge role. If the length of the rocket is too long then the cones will be useless. On the other hand, if the length of the rocket is too small that will also not benefit the rocket. The length of the rocket should be ideal and circumstances should be taken in consideration. The reason behind the structure of the nose cone is cylindrical in shape is because that way the friction that is caused on the rocket by the wind will be reduced. Another part that helps the rocket to stay stable is the fins. Without the fins rocket will not go upwards properly and will not be able to fly. Fins are designed in order to itself up while still in motion. This theory can be proved by Newtons third law of motion, which states that, every action has an equal and opposite reaction. In this case, the drag and gravity are pulling the rocket downwards and the fins are pushing it upwards. Several fins follow the same design structure. They are wider at the top and pointier at the bottom. The reason they are more sharp at the bottom is so that they can cut through the air while they are still in the motion. There are mainly four fin shapes: square, trapezoid, triangle, and epsilon. Triangular or and epsilon fin would be ideal for a rocket since it create less drag. Furthermore, a parachute is needed to land the rocket safely. However, adding a parachute to the rocket adds more mass, which will eventually affect the rocket to reach the maximum height possible. Therefore, keeping the rocket light weighted in the beginning and keeping in consideration about the mass at all times does not affects the rocket later on . The reason mass is kept into consideration is because as the mass of the rocket increases the gravitational force acting on it also increases, Fg = mg. In addition to that, another thing to keep in consideration while building a rocket is that it should survive the harshest and most extreme conditions possible. Keeping the rocket fireproof, by adding a piece of tissue between the parachute and the engine would stop the heat from the engine to reach to the parachute when the rocket is still in motion. To conclude with, rockets are really hard to engineer as each concept is kept in mind while constructing them. Every little thing attached to a rocket affects it directly or indirectly. When rockets are in space, anything can go wrong, so the engineers lways have a backup safety plan for the astronauts safety. A rocket engineer is one of the hardest professions, since so many factors are kept in consideration and much thinking is required. Purpose This lab had various purposes. However, the main reason we did this lab was to achieve the maximum height possible with limited material provided. Another purpose of this investigation was to apply our knowledge regarding Newtons three laws of motion since the amount of air resistance was present. An additional purpose would be to determine the relationship between the mass of the rocket to ts: Acceleration, Ek, Eg, Fg, Fnet, etc. Another reason this lab was conducted was to observe, how things are affected on this planet while they are still in motion and are above earths surface. The overall purpose of this lab was to combine all the knowledge from the previous units and to build a rocket that could reach maximum height possible.

What is Defamation †Law Essay

What is Defamation – Law Essay Free Online Research Papers What is Defamation Law Essay The law of defamation was meant to protect peoples reputations from unfair attack. Over the years, however, it has mutated into a heterogeneous mess invoked by the rich, who can afford to hire people clever enough to navigate the maze that is todays defamation laws, to protect exclude themselves from public scrutiny and criticism. To make things worse, defamation law differs from state to state, allowing those with deep enough pockets to shop around for the jurisdiction that most suits their needs. The sorry state of defamation law in Australia has prompted various calls for reform dating back from when Gareth Evens first took office as Commonwealth Attorney-General in 1983. Yet it is only recently that we seem to be headed for nationally uniform defamation laws. The proposal by the States is likely to bring more uniformity and less confusion to the law of defamation. However, it is likely to be clobbered by the national proposal from the Commonwealth Attorney-Generals department, which is likely to keep defamation in its current place as a weapon for the rich and powerful. One need only examine the proposed amendment to the truth defence to see an example of how defamation can be used by those who can afford to invoke the wrath of the law to protect them from scrutiny. But before we can criticise the proposed truth defence, we need to understand the purpose of defamation law. Purpose of defamation For the purposes of this essay, discussion of defamation will be restricted to the civil tort, which is meant to clear the reputation of the defamed. The criminal offence is meant to punish defamers and protect the community, so would be less of a tool to be used to avoid scrutiny. In fact, because of the level of proof required, a criminal trial may increase the level of scrutiny on a victim relating to the alleged defamation. The law of defamation historically refers to an aggregation of laws relating to slander and libel. Its purpose is and always has been the protection of peoples reputations. The basis for this was an acknowledgement that a good reputation took time and money to build up, like a house. This meant damage inflicted upon it should afford a remedy in the same way that vandalism affords a remedy to property owners. It should be noted that defamation protects a persons reputation, not their character. It does not afford a remedy for wounded pride, sleepless nights, or hurt feelings. Instead, defamation only rectifies damage the the view others hold of you. The distinction between reputation and character is an important one, which has been confused even by judges. Another source of confusion is the cause of action in defamation. When a defamatory statement is published, it is not the reprehensible motive of the publisher that gives rise to an action, but rather the effect of the statements published (and whether there was a legal basis for their publication). Defamation does not punish a publisher for thinking malice towards the victim, but rather for hurting the victims reputation. In this way, it is similar to the tort of negligence, which is not concerned with the intent of the negligent party, only the effect of their actions (and whether they fulfilled their legal duty). The protection of peoples reputations inevitably will come into conflict with any pre-existing right to free speech. Defamation law has to balance these two rights, weighing the right to free speech against the right of people to their reputations. Today, free speech is encouraged by allowing people, at the common law to publish the truth without fear of being liable for defamation. The problem with privacy Whats private? Definition difficulties. Whatevers private is removed from public discussion. Defamations no good for protecting privacy.

Failure of democracy in developing countries Research Paper

Failure of democracy in developing countries - Research Paper Example According to the Economist Intelligence Unit’s report on the status of democracies in the world, in 2014, almost 70% developing states’ democratic governing systems were characterized as the â€Å"flawed democracies.† According to the report, deficiencies in the governing process, electoral system, political culture, and civil rights have played a crucial role in failure of democracies developing states. After the end of the World War II, especially during the Cold War era, western powers were engaged in aggressive promotion of democracy in developing and third world countries. During the period, democratic peace theory, which was introduced by Immanuel Kant in 1795, emerged as the widely recognized theory in the global politics and academic spheres. This theory is the core of western promotion campaigns of democracy in developing states. According to the theory, democracy plays a vital role in development of economic stability, security and peace. The theory further claims that democratic states are usually peaceful and comparably less war-oriented. Therefore, it is assumed that the larger the number of democratic states in the world will lead to the less possibility of war and the greater assurance of social and economic stability and peace in the society. On the basic of various scholarly researches and available data, the present paper provides numerous pieces of evidence that w ill cast serious doubts on the validity of the democratic peace theory. In other words, by confuting the major assumptions of democratic peace theory, the paper exposes the failure of democracy in developing world and argues that only the potential spread of democracy won’t lead to more secure world, rather flawed and unmethodical promotion of democracy can lead to more instability and insecurity in the world. Since the period of Cold War, Western powers have

The Philosophic Solution for Self-realisation Essay

The Philosophic Solution for Self-realisation - Essay Example Substance abuse like alcoholism although is an associated outcome of depression, Peter our subject was in the clutches of alcoholism well early in his adolescence. The behavioral problems and emotional problems encountered by Peter reveals that the treatment for his depression received from the GP did not include any treatment with antidepressant drugs, as detection of depressive disorders did not found associated with long-term outcome. (Anderson I.M., D.J.Nutt, J.F.W.Deakin, 2000). The case study of Peter is difficult to be discussed in the absence of any information about his mental status, Conversation styles, and intelligence. However, a history of cross-gendered behavior in adolescence is doubted to have caused the homosexual trait in him. The family background of Peter especially of his parents is of much importance to fix the location of his homosexuality, which unfortunately is absent in our study. It is not clear if Peter was forced to be a misogynist in his youth or not. Hence his homosexuality could only be ascertained theoretically with the help of literature available. 1) This theory accounts for the higher incidence of alcoholism in gays than heterosexuals. This theory explains that gay bars are the one and only place where gays are able to meet their fraternal mates. This ‘fraternity syndrome’ spreads a compulsive drinking habit among the gays. 2) These theories hold that internalized homophobia, self-hatred, shame and so on, the external oppression of a homophobic society and hiding one's identity are as important as gay bars in understanding the etiology and incidence of their alcoholism. 3) This theory comprises three stages. In stage I a gay man accepts his gayness as appositive one. In stage II, while seeing the self in negative state tries to rid the self of homophobia by learning more about the gay world.

Sociology culture Essay Example for Free

Sociology culture Essay Question 1. What do chimpanzee and orangutan cultures have in common with human culture? Give examples of specific behaviors. Answer 1. These cultures are common because both have tool use, complex grooming and courtship. For example, young chimpanzees are taught how to crack nuts and when they run into technical problems the mother is always there to help them. This is quite like how humans would react. The parents teach the young how to complete and overcome certain task. Another example is the â€Å"leaf clipping† behavior. Just like how one set of humans might use one thing for a certain task, whereas another set might use the same thing for a completely different task is basically the same as how different sets of chimpanzees use the whole â€Å"leaf clipping† behavior. Question 2. Find the article on orca culture by Lisa Stiffler cited above. How do findings about orcas differ from those about chimpanzees? Answer 2. The findings about orcas differ from those of chimpanzees in many different ways. Even though they both have a complex culture, orcas communicate in a different ways, they move in groups led by females, they have different ways of pleasing themselves such as rubbing their bodies along rocks and they eat different things. Some orcas eat simple things like salmon others eat things like seals, sea lions and even sharks. One major difference is that instead of the mother Orca forcing/teaching the child how to obtain it’s own food like the chimpanzee learning how to crack nuts; the mother orca instead hunts the food, holds it in her mouth and allow her calves to chew on it. To top it all of orcas are also used for greeting ceremonies in some countries whereas Chimpanzees aren’t. Question 1. How does the culture of the Trobiand Islander affect their way of creating a calendar? Answer 1. Due to the fact that agriculture is the main focus of people’s lives within the Trobian Islanders, their calendar is based on the lunar cycles. Instead of having a fixed number of months, the number of months in a year for them could either be 12 or 13. This happens because they use the internal clock of a marine worm and basically decide how many months would be in a year based on this worm’s timing. If the worm does not show when they expect it to show, they would repeat the month hereby determining whether they’ll be 12 months or 13 months in the year. Question 2. What is another example of a calendar system that is not the same as that used by the majority of people in the United States? With what culture is it associated? Answer 2. Another example of a calendar system is the Mayan calendar. This calendar contains three different calendars; the Long Count, the Tzolkin and the Haab. These calendars in the Mayan system vary in the number of days as well as the number of months. It was used by most pre Columbian Central America cultures including the Maya around 2000 BC to the 16th century. However, the calendar got developed further by the Maya civilization and up to this day it is still in use by some of the Mayan communities.

Tender Reports in Construction

Tender Reports in Construction Tender report is an analysis or evaluation report that was prepared by a quantity surveyor about the tenders which submitted by the tenderers. This report was prepared to give suggestions to the public sector client, i.e. the government or the private sector employer about the best contractor for the project through evaluating the submitted tender documents in various aspects and to establish a price for the ensuing contract. After taking the recommendations from tender report and advice from the consultants into consideration, the client or employer will select his or her preferable choice of contractor. The throughout process and results of the tender evaluation are keep confidential. Upon the submission of tenders from the tenderers, a Tender Board or a Tender Assessment Panel will be formed. Tender Board or Tender Assessment Panel is a group of independent officers which included the quantity surveyor, to carry out a tender receipt process for competitive tenders, revise and confirm best and final offers. The tender board meets on a set date at a specified time to open and process tender documents submitted which they then forwarded to acquisition teams for commercial, technical and financial evaluation. The Tender Board will ensure that tenders are opened and processed in an open and transparent way. In addition, the tenders will be evaluated and recommendations will be made to the the client and the Tender Board. The approval and acceptance of a tender is made within the validity period of tender, which is normally 60 days as set in the tender document. To avoid the extension of one tender, tender should be evaluated and recommendation made within 30days from the date set in the handing over of tender. In case tender has to be extended due to unavoidable circumstances, agreement from the recommended tendering party should be obtained at least two weeks before the expiry of validity date. Generally, the tender evaluation process can be divided into two stages, i.e. preliminary stage evaluation and final stage evaluation. The preliminary stage of tender evaluation or also known as Preliminary Analysis, comprises of analysis on completeness of tender, analysis on compulsory documents and analysis on minimum capital required for the project, whereas the final stage of tender evaluation comprises of analyses on technical and financial capabilities of the tenderers. Besides that, arithmetical check will also be carried out on the tenders along the tender evaluation process. Before the tenders to be taken into consideration, the precondition of tender evaluation is the tender must be submitted before the tender closing date and time set out in the Letter of Invitation to Tender, i.e. usually before 12.00pm noon of the tender closing date. If the tender was submitted later than that, it is fall under the category of late tender. Late tender will not be accepted or of submitted, not opened for further consideration due to reasons of fairness and accountability. This is normally applied to public sector projects where the standards pertaining to transparency and accountability are especially high. However, the decision whether to open and consider such a tender is purely at the discretion of Tender Board and the private sector employer. Furthermore, tender amended by the tenderer on his or her own initiative whether in writing or other forms, without consent from the project client or employer will also be rejected for consideration. After that, the Quantity Surveyor will conduct the preliminary or first stage of tender evaluation process, i.e. Preliminary Analysis. It is an assessment system based on a few precondition set to determine whether the tenderers are qualified to be considered for the next stage evaluation. Purposes of this assessment system are to ensure that the tenderers to be considered are reasonable in term of tender price, complete of required documents and have sufficient capital to commence works. Firstly, the Quantity Surveyor will analyse the tenders whether the tenderers have offered the reasonable tender price. For government projects, if the number of tenderers is less than 10 persons, the department estimate or consultants estimate will be used for the comparison of tender prices. Usually, a variation price of 15% of department estimate or consultants estimate for tender prices offered by tenderers is assumed reasonable. If the number of tenderers is 10 persons or more than that, the Public Works Department will adopt the cut-off method to shortlist the tenderers for further evaluation. A cut-off price is established as the minimum tender price which is assumed feasible and reasonable to be accepted in accordance to market price through a statistical method. This is to avoid project implementation failure due to the contractors inability to undertake or complete the works caused by awarding contract to a tenderers with too low or unrealistic tender price. Therefore, usua lly only tenderers with tender price above or equal to the cut-off price will be considered and evaluated. In addition, completion period proposed must not exceed the range of estimated completion period. Then, the Quantity Surveyor will check the aspect of Completeness of Offer or Tender submitted by the tenderers. Some elements of Completeness of Tender which taken into consideration are the Form of Tender must be signed, the signature must be the authorized person, tender price must be stated in the Form of Tender, registration with Contractor Services Center (PKK) or Construction Industry Development Board(CIDB) must be valid and have stated the proposed completion period. Only tenders that complete and free from any deficiency or mistakes which may affect the current contract practices in legal aspects, are qualified to be considered. Tenderers which failed to do so, their tenders will be mentioned as INCOMPLETE to the client and stated the reasons. The following process is to check the aspect of Sufficiency of Compulsory Documents. All tenderers are obliged to submit all compulsory documents needed which stated in the Instructions to Tenderers for the tender evaluation purpose. The compulsory documents are the company auditors report, bank accounts monthly statement, banks report on company financial status and report on current project by resident architect or resident engineer or project manager. These documents are needed to prove whether the tenderers have sufficient financial capability, i.e. possess minimum sufficient capital to start the works. Without submitted the compulsory documents, especially for company financial documents, tender evaluation cannot be carried out and that tender is not qualify to be considered and can be rejected. Besides, an analysis on minimum capital required for the project will be conducted. The analysis will be done on the companys current assets, current liability, bank account statement, fixed deposit, bonds, credit facilities from bankers or suppliers, overdraft and bank loan. Hence, the company financial documents submitted by the tenderers will form a basis or proof for this evaluation aspect. For government projects, the minimum capital analysis is made through calculation of 3% of the Builder Works value based on department estimate. Along the tender evaluation process, the Quantity Surveyor will carry out the arithmetical checks on the tender documents. It comprises of correcting arithmetical errors in extensions, casting, etc and isolating palpable errors on pricing, but the tender amount remains unaltered. This measure is to correct mistakes for the purpose of future variation. A detailed examination of Bills of Quantities including comparison of prices will also be carried out on all tenders submitted. If the tenderers have fulfilled all the requirements in the preliminary stages evaluation, then the tenderers are considered or qualified for the final stages evaluation. The final stages evaluation is carried out based on a marking or scoring system which the marking are made objectively and quantitatively for each criterion assessed. Firstly, it will analyse the tenderers first aspect of technical capability, i.e. experience. Assessment is made based on the total value of same and similar nature of tendered works completed in the past five years. This is to get know that whether the tenderer is capable or have similar nature of works experiences for the tendered project. Next, it will analyse the tenderers second aspect of technical capability, i.e. financial. It is based on the total annum value of project predicted to be provided from the tenderers various sources of finance. It is important to prove that the tenderer has the financial capability to execute the project. Marks are given according to their financial capability. After this, it followed by the third aspect of tenderers technical capability assessment, i.e. the technical workers and possession of basic plant and machinery. Assessment is made based on their technical workers, such as architects, engineers, quantity surveyors, technician, and polytechnic and technical works assistants. The tenderers need to submit the KWSP statement and photocopies of Certificates of Workers Qualification to prove that they have qualified and enough number of technical workers to execute the tendered works. The lists of plant and machinery with supporting documents are also required to submit for the evaluation. Lastly, it will analyse the tenderers current works performance. This analysis is aimed to ensure that the tenderers do not have projek sakit, i.e. projects lagged behind 30% or more from the schedule of works or works programme. In addition, it is important to ensure that the tenderers do not have problems of employments determination by other client or employers. After the both preliminary and final stages of tender evaluation have completed, the results, justification, recommendation, and tenderers necessary detail information and facts will arrange and compiled together in a systematically way to form a tender report and submit to the client or employer. In conclusion, tender report is produced to assist the client or employer in decision making process in order to select most suitable and capable contractor to complete the project within specified time and quality.

AOW

A crowd stood and watched, waiting to see what the police would do. â€Å"l am trying to allow homeless people to have the same rights as everyone else,† said Mr.. Abbott, who has ignited a skirmish with the city over new restrictions on feeding the homeless in public places. â€Å"There is no rug big enough to sweep them under. † Once again the police issued him a notice to appear in court for the criminal violation of an ordinance -? the third one in nearly two weeks -? and then allowed Mr.. Abbott, who has worked to help the homeless for decades, to resume serving food to those waiting in line. And once again Mr..Abbott, who has become a cause cl;bare, vowed to continue to feed the homeless â€Å"as long as there is breath in my body† -? be it at the beach or in a park. To press his case, Mr.. Abbott also said he took the city to court on Wednesday, a tactic he used successfully nearly 15 years ago to beat back a similar local ordinance. Mr.. Abbot's stance ag ainst the city newest restriction on the homeless has put him at the center of an escalating debate in cities across Florida: How to feed, elf and handle the ever-present homeless population in a state that, with its balmy winter climate, draws an outsize share of the dispossessed.In 201 2, the state had nearly 55,000 homeless people, ranking third behind California and New York. â€Å"We have no desire to fight with Mr.. Abbott,† said Jack Seller, Fort Lauderdale mayor, who has spent days tying to counter reports that Mr.. Arnold had been arrested (he was not) and that his city is harsh on homeless people. On one side of the debate are local businesses and the chambers of commerce, which would like the homeless population to be less visible. On the other side are increasingly vocal homeless activists who want to ensure that homeless people are dealt with humanely.The balancing act is particularly tricky in Florida, where tourists blanket the state and tourism officials cring e at the thought of scared tourists. â€Å"Florida has had a sorry history of criminality the homeless,† said Michael Stoops, director of community organizing for the National Coalition for the Homeless. ‘That war is being played out all around the country. Florida leads the pack. † This year, Fort Lauderdale, despite a reputation for being more progressive than most Florida cities on homelessness, passed a series of measures that surprised and drew the ire of homeless activists.The latest one, passed last month, made food distribution in public places difficult by requiring toilets, written consent from property owners and feeding sites located 500 feet away from each other. But the law also relaxed the rules on feeding the homeless in houses of worship and on private property, an attempt to steer food distribution away from parks. On Wednesday, a police officer recommended two nearby sites to Mr.. Abbott, an offer the mayor said Mr.. Abbott had refused earlier i n the day.The new ordinance stemmed from long-running complaints about crowds of homeless people who congregated daily to wait for food at Astrakhan Park, a small park in front of a library and the Fort durable Woman's Club. ‘The Woman's Club said it couldn't hold any more weddings, events with children, yoga classes,† said Mr.. Seller, who underscored that most experts agree that handing out food in public spaces is a bad idea ‘They said: ‘Mayor, we have people urinating all over our property and porch, defecating on our property and our porch. There is garbage and litter.There is no respect for Our property. ‘ † Ronald L Book, chairman of the Miami-Dade Homeless Trust, said public feedings were typically counterproductive. â€Å"There are ways to help within the boundaries of the rules: feeding indoors,† he said. If not, he added, â€Å"You sustain them on the street, and that's not a good thing. † The city other new ordinances inc lude restricting panhandling at intersections and allowing the police to confiscate and store property left in public spaces. Similar laws -? and opposition to them -? have cropped up across Florida.

Small Towns Big City

Costumes Bring out Different Personalities Pulling up in the parking lot there are small groups of people crowded around getting out of their cars and preparing to enter the building, there is laughter and talking throughout the parking lot leading up to the building. Everyone is dressed in costumes for the theme of the party; there are mummies, zombies, cartoon characters, fairies, devils, musicians, super Heroes, cowboys and cowgirls, and many more. Everyone wearing a costume seems to present a more outgoing and somewhat â€Å"false† personality relevant to the character or thing that their costume is portraying.As we walk closer to the entrance from the parking lot you can hear the music, and the noise of the people inside. The music is loud and draws a crowd towards the doors. When we arrive at the entrance to the building there is a lady about five feet five inches tall with light brown shoulder length hair wearing a cowgirl outfit, standing behind a booth, checking Ident ification to ensure everyone who enters is at least twenty one years of age, and also collecting the entrance fee from each person. She’s talking with a fake country accent that helps add character to her costume.Her personality is bubbly and welcoming; it sets the tone for what the atmosphere is inside the building. There is another person at the entrance, a man standing beside her he is tall about six foot five or so, he has short brown hair and is wearing a uniform shirt instead of a costume. His personality is more calm and natural; I feel that this is because he is not in a costume so he doesn’t have the same ramp up as the others who are in costume have. He checks everyone’s bags for weapons, alcohol, and anything that would not be permitted inside the building.He then places a paper bracelet around each person wrist to identify that they have been checked through security, and are permitted to enter the building, this also helps the bartenders identify th at the person they might be serving alcohol to have been verified as over the age of twenty one. When we walk in the front door the noise of laughing, talking and the music has gotten much louder, it is now clear what the atmosphere in the building is, there are people everywhere, talking, drinking, and having a good time, it seems fun and relax, entertainment is everywhere.No matter what direction you turn there are so many different smells, but with the huge crowed of people the strongest of all the smells would by far be the body odor. Straight ahead as soon as you walk in the door there is a bar where a bar tendered dressed in a devil costume stands taking orders and making drinks, she seems busy and more mute then the rest of the employees, but every once in awhile she will scowl in a fun way at someone in character to her costume.There is a large line of people surrounding the bar waiting for their turn they are all laughing and some are even in a playful mood using props to t heir costumes as weapons to battle with each other. To the left is a long table of people, a dance floor, and a DJ station. Looking to the right there is more small grouped tables, restrooms, and a door to an outside area where people are smoking and talking. There is a group of people standing outside dressed as the ghost buster crew, they are all acting out scenes from the movie, they are sure to stay in full character through the entire scene.Their enthusiasm is entertaining to say the least, and it draws a crowd of people. Others start to join their lead, there is a small group of pirates that are also sward fighting and talking in accents that suggest their characters. The outside atmosphere is more playful then inside and is also a little quieter. Overall everyone is having a good time and the theme of the party is in honor of the holiday Halloween.There is costume contest that everyone was encouraged to enter, it seems to ramp up the excitement throughout the building, everyo ne begins to gather around the stage. They had everyone who entered the costume contest line up on stage one by one. The costumes were judged by the crowed in a scale of how loud their yelling was. As each person was presented in the line of contestants they acted in a way to present the character of their costumes. There was a woman dressed up as a lion tamer, and another woman with her dressed as a lion.They acted out a scene when it was their turn on stage. The tamer attempted to tame the wild lion while the lion persistently tried to attack the tamer. As the night goes on the atmosphere changes, everyone has obviously had a lot more to drink and the levels of intelligence have diminished. As I look to my left by the dance floor I see a fight between two girls, there are shoes flying, and a crowd of people quickly gathering to get in on the action. This is now becoming an atmosphere that I may not want to be in for much longer.Although the festivities are quiet entertaining and a drenaline is pumping with every move from the dance floor it is now clear that the night is almost over. As the bouncers approach the crowed they move through aggressively to break up the fight, and sort out what has happened. I watch intently to see the damages that are done its almost sad how entertaining this has become. Once the fight has been broken up, those involved in the fight, and the bouncers all leave out of the building, the party then goes on.The DJ makes an announcement that this will be the last song and the party will soon end. As the last song comes to an end the crowd of people being to leave out the front door. Everyone is still playful and maintain their characters as they gather around their vehicles and begin to reverse the entire process. Overall the night was entertaining to say the least the costumes created an atmosphere that was out of the normal and would most likely not have existed if it wasn’t for the costume and the theme of the party. Clear a nd engaging introduction that clearly states a strong thesis: 14/20 While engaging and full of detail, there is no clear thesis or map. Something like, â€Å"this was a great party because of the atmosphere, the costumes, and the mood† would have worked. * Clearly established supporting details, in the form of observations, that support your thesis: 15/20 There are lots of supporting details, but because the framework is missing, it is unclear what those details support. * Transitions and Topic Sentences: 15/20Don’t forget topic sentences at the start of every major point. They need to provide a transition, a connection to the thesis, and the topic/point of the paragraph/section. Therefore, when you start discussing atmosphere something like â€Å"Another reason why the party was so much fun was the atmosphere† would have worked. * A conclusion that reinforces the focus and dominant ideas in the text: 18/20 * Engaging Tone and Style:5/5 * Grammar, Punctuation, a nd Spelling: 8/10 * MLA Header and title: 5/5 GRADE: 80

No matter if, it was good or bad times nothing can or could surpass to compare to the gift of becoming a mother. There are so many memories wrapped in this these packages of happiness, joy, and even times of fear knowing they don't come with instructions, but to learn as time goes on. From the first moments as a mother when coming into my world was like a new beginning of the chapter of life. All my worries and fears of becoming a mother had been washed away, I knew that moment of time life wasn't going to be the same. I was going to take life day by day and enjoy my life with my new family not to be so concerned about the small details that life brings.John Lennon AnthologyMy life has become complete, I feel as though with this fresh start that myself as one can complete my dreams and hopes to a better future for us.

Free Essays on Population Disaster

Population Disaster? The People’s Republic of China is a vastly populated country. The inhabitants of the country make up approximately twenty percent of the world’s population. For nearly 2,000 years, the population of China fluctuated between 60,000,000 and 110,000,000. When the People’s Republic of China was founded in 1949, the population was approximately 540,000,000. Within three decades, the population had increased to over 800,000,000. During the next three decades the population is expected to increase by over 260,000,000. Although this is not as tremendous an increase as in the first thirty years of the country, this number is equivalent to the total population of the United States. This increase is driven by the high fertility rates of the 1950’s and 1960’s, which averaged between 5.6 and 6.3 children per woman. During the 1970’s and 1980’s the fertility rate dropped to around 1.8 children per woman. Even though the fertility rate has dropped, the population will continue to experience tremendous growth because of the large number of young adults of reproductive age. The United Nations Population Division estimates that China’s population will grow to 1,490,000,000 by 2025, but will decrease slightly to 1,480,000,000 by 2050. This decline is a result of China’s government enforced one-child policy. Some 58,000 children are born every day in China, which averages out to 20,000,000 births each year. This number would be much higher if not for the one-child policy. Pregnancies must be authorized and women must obtain a birth coupon before conception. Couples who do not follow these procedures have fines imposed upon them, sometimes amounting to more than what they would earn in an entire year. This one-child policy has also resulted in the mass murder of infant girls. Many female fetuses are aborted because of the strong preference for boys in the country. Upon birth, girls are routinely... Free Essays on Population Disaster Free Essays on Population Disaster Population Disaster? The People’s Republic of China is a vastly populated country.

Knowledge of An Organisation - Research Proposal Example nt position in this as they are the real â€Å"knowledge producers† and hence any new knowledge that a company looks for is produced courtesy through these people. (Rocca, 1992) Competitive success is basically commanded by the companys capability to harness and indeed develop new forms of knowledge, gained either by observation or by experience attained, which can be called as assets that in turn create the required â€Å"core competencies† of the said organization. While these competencies do exist in many forms, learning on the part of a particular company plays a pivotal role, which eventually ventures into other resources of knowledge to generate high-class and exceptional showing from the company’s employees. (Dunn, 2001) Core competencies, which usually flow out of a company, provide characteristic benefits to both the customers as well as any other individuals attached with it. These are generally espied as being the foundation of forming a competitive advantage within the said company. It is quite true that there is a host of ways in which new knowledge within a company is facilitated within its ranks. The need here is to classify the m with respect to their importance, which include the cultural infrastructure can be changed within a company so as to gather some proportion to the fact of the actual remains that have to be taken care of in the company and in its employees’ minds. It demands idealization and disclosure of everlasting knowledge that is created over a certain period of time. This usually requires basic changes to already set cultural notions in companies and more so in the minds of their employees. (Fahy, 1996) Also operational infrastructure is changed through human resources organizational practices that are managed and received by the employees and other people in a different way altogether. A basic revamp of a knowledge-centered company is required here, which would involve the job ladders, compensations, work locales and command and
