Resilience Essay for Unbroken by Laura Hillenbrand free essay sample
Resilience is a word that few people know of and even fewer people possess it as a character trait. It means to be able to bounce back from something quickly. It can be developed from a tragic event that happened in oneââ¬â¢s life or even a series of events that would break down a normal person. Resilience is a trait possessed by these four people who have definitely encountered and are still living through life changing events. Those four people are Laura Hillenbrand, Louis Zamperini, Russell Phillips, and Fred Garrett. Laura Hillenbrand is becoming a world sensation after writing her bestselling book, Unbroken. Sure she may seem like she is living the dream life with thousands of people buying her books every day, but what most people do not know about her is that she suffers from Chronic Fatigue Syndrome, a disease that drains all energy from the body and leaves it feeling lifeless and overly tired. We will write a custom essay sample on Resilience Essay for Unbroken by Laura Hillenbrand or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The disease keeps her on bed rest for many of her days but she still finds time to write bestselling novels. She is resilient in that because even though she is living with Chronic Fatigue Syndrome, she does not let it stop her from living her life and doing what she loves. She developed the disease while on a road trip with her boyfriend and other friends. They were driving along a highway when a deer began to step into the road. The car barely missed the deer by a few inches. Later that night a meteor came streaking across the sky. She was the only one who saw it. She then became very nauseous. Her boyfriend thought she had food poisoning but he would later learn that she had developed CFS, or Chronic Fatigue Syndrome. Louis Zamperini is a World War Two veteran and the main character of Laura Hillenbrandââ¬â¢s bestselling novel, Unbroken. Louis was born on January 26, 1917. As a child, he was constantly on the go and causing trouble. It did not matter how many times he was caught, he always went back to wreaking havoc on the streets of Torrance, California, the town where he grew up. By doing so, he developed resilience. When he was a teenager, he ran track for his high school team. He then went to the 1936 Olympics in Berlin, Germany on the United States track team. While in Berlin, a group on opposing runners boxed him in during a meet and cut his legs all to pieces using the pikes on the bottom of their cleats. He never let that stop him. He managed to bounce right back. When he went into the U. S. Air Corps, a plane he was on called, The Green Hornet, crashed into the middle of the Pacific. He and two other men were the only survivors. It was forty-seven days before he saw land again. That did not break him either. He was captured as a prisoner of war in Japan where he was beaten, starved, and he contracted many diseases. He pulled through and returned to his normal state upon arrival back on United States soil. Russell Phillips was a pilot for crew number eight in the nine-crew 372nd bomb squadron of the 307th bomb group, seventh Air Force. He flew the plane that carried Louis Zamperini. Phillips was born in Greencastle, Indiana, in 1916. When he was a boy, he was a lot like Louis. He was quiet on the outside but inside he had a wild streak. When he was in ROTC, his captain called him the lousiest-looking soldier. He never let that get him down. He proved to be a fine airman. He flew his airmen to through very dangerous bombings and all survived but one. He survived the crashing of The Green Hornet along with two others. He then survived forty-seven days in a raft floating through the Pacific with Louis and a man named Mac. Like Louis, Phillips survived the prisoner of war camps and took all of the beatings. He would not be broken by the Japanese. He too bounced back from the trauma. A good friend of both Louis and Russell was enrolled as an airman for the United States Air Force. He was an amputee with only one leg. He lost it upon his arrival in a Japanese prisoner of war camp. He injured it and it soon became badly infected. Because of this, a Japanese doctor amputated his leg off at the knee. He was able to show resilience though and recovered rather quickly. He also was a resilient survivor of the prisoner of war camps. Now all of these people are resilient in one way or another. Some were told they would never make it. Another is fighting a disease. One has a physical disability. Others were beaten down further than any human being should be. After all that they have been through, at the end of the day, they remain unbroken.

Palladium Facts - Periodic Table of the Elements
Palladium Facts - Periodic Table of the Elements Palladiumà is a silvery-white metallic element with atomic number 46 and element symbol Pd. In daily life, its most often found in jewelry, dentistry, and catalytic converters for automobiles. Here is a collection of useful and interesting palladium facts: Essential Palladium Facts Atomic Number: 46 Symbol: Pd Atomic Weight: 106.42 Discovery: William Hyde Wollaston 1802 (England) Wollaston noted his discovery of the metal in 1802 and offered the purified element for sale in 1803, although there was some controversy regarding the discovery. Richard Chenevix believed Wollastons palladium to be a platinum-mercury alloy. Chenevixs palladium experiments earned him the 1803 Copley Medal, but its clear Wollaston did at least partially purify the element. He dissolved platinum order from South America in aqua regia, neutralized it with sodium hydroxide and precipitated out the platinum. Reacting the remaining material with mercuric cyanide formed palladium(II) cyanide, which was heated to yield the purified element. Electron Configuration: [Kr] 4d10 Word Origin: Palladium was named for the asteroid Pallas, which was discovered approximately the same time (1803). Pallas was the Greek goddess of wisdom. Properties: Palladium has a melting point of 1554à °C, boiling point of 2970à °C, specific gravity of 12.02 (20à °C), and valence of 2, 3, or 4. It is a steel-white metal which does not tarnish in air. Palladium has the lowest melting point and density of the platinum metals. Annealed palladium is soft and ductile, but it becomes much stronger and harder through coldworking. Palladium is attacked by nitric acid and sulfuric acid. At room temperature, the metal can absorb up to 900 times its own volume of hydrogen. Palladium can be beaten into leaf as thin as 1/250,000 of an inch. Uses: Hydrogen readily diffuses through heated palladium, so this method is often used to purify the gas. Finely divided palladium is used as a catalyst for hydrogenation and dehydrogenation reactions. Palladium is used as an alloying agent and for making jewelry and in dentistry. White gold is an alloy of gold which has been decolorized by the addition of palladium. The metal is also used to make surgical instruments, electrical contacts, professional transverse flutes, and watches. In photography, palladium is an alternative to silver, used in the platinotype printing process. Sources: Palladium is found with other metals of the platinum group and with nickel-copper deposits. The primary commercial sources are the Norilsk-Talnakh deposits in Siberia and the nickel-copper deposits of the Sudbury Basic in Ontario, Canada. Russia is the primary producer. It may be produced in a nuclear fission reactor from spent nuclear fuel. Health Effects: Palladium, like the other platinum group metals, is mostly inert in the body as a bulk metal. However, there are reports of contact dermatitis, particularly in persons allergic to nickel. This causes problems when palladium is used in jewelry or dentistry. In addition to these uses, environmental exposure to palladium comes from release by automotive catalytic converters, food, and workplace exposure. Soluble compounds of palladium are excreted from the body within 3 days (99 percent). In mice, the median lethal dose of soluble palladium compounds (e.g., palladium chloride) is 200 mg/kg orally and 5 mg/kg intraveneously. Palladium is poorly absorbed and its toxicity is considered low, but it may be carcinogenic. Most plants tolerate it when it is present in low concentrations, although it is lethal to water hyacinth. Palladium serves no known biological role. Currency: Palladium, gold, silver, and platinum are the only metals that have ISO currency codes. The codes for palladium are XPD and 964. Cost: The price for palladium continues to rise. In 2016, palladium cost about $614 per ounce. In 2018, it reached $1100 per ounce. Element Classification: Transition Metal PalladiumPhysical Data Density (g/cc): 12.02 Melting Point (K): 1825 Boiling Point (K): 3413 Appearance: silvery-white, soft, malleable and ductile metal Atomic Radius (pm): 137 Atomic Volume (cc/mol): 8.9 Covalent Radius (pm): 128 Ionic Radius: 65 (4e) 80 (2e) Specific Heat (20à °C J/g mol): 0.244 Fusion Heat (kJ/mol): 17.24 Evaporation Heat (kJ/mol): 372.4 Debye Temperature (K): 275.00 Pauling Negativity Number: 2.20 First Ionizing Energy (kJ/mol): 803.5 Oxidation States: 4, 2, 0 Lattice Structure: Face-Centered Cubic Lattice Constant (Ãâ¦): 3.890 Return to the Periodic Table References Hammond, C.

Attraction Visit and Analysis for Eureka Skydeck - myassignmenthelp
Eureka Skydeck is one of the most popular tourist destinations of Melbourne. The Skydeck is located on the 88 th floor of the 91 storied Eureka Tower, providing the highest public view in the Southern Hemisphere at 935 ft (285 m) above the sea level (planetware.com 2018). In the heart of the Southbank of Melbourne, by the Yarra River, the attraction was built from 2002 to 2006. The tower is the tallest one in Melbourne and second tallest in Australia, after Q1 in Queensland. The tower was named after the Eureka Stockade, the rebellion at the time of 1854 Victorian gold rush and hence, the design has incorporated a gold crown at the top of the building representing the gold rush (Eureka Skydeck 2018). The Skydeck also features The Edge, a glass cube projecting outside the building providing a 360 degree view of the city. Eureka Skydeck has a complete website with all the relevant information about the observation deck. Right from the ââ¬ËAbout Usââ¬â¢ to ticket pricing, things to see, education, dining and many more, the website is filled with all sorts of information and pictures. Visitors can check out www.eurekaskydeck.com.au to get the detailed information before visiting this attraction. The website is user-friendly as it contains easy links to important information along with photos of the visitors. It also has multilingual options for visitors, not having proficiency in English only. It is located in the Riverside Quay in Southbank of Yarra River, which is easily accessible by public transport. All the public buses, trams and trains, crossing the Flinders Street Train Station and St. Kilda Road can be availed by the tourists to reach Eureka. Parking options are available at the Wilson Eureka Parking at the cost of AUD 13 for Monday to Friday, entry prior to 4pm, AUD 6 for Monday to Friday, entry after 4pm and AUD 11 for the weekends (Eureka Skydeck 2018). There are plenty of other parking spots at reasonable prices nearby where visitors can park their cars and bikes. The Skydeck has all the modern facilities such as, toilets, disabled ramp to the entrance, souvenir shop, with variety of gift products, free WiFi area (Yoo 2017), small cafes for sandwiches and hot drinks, small seating arrangements and a fine dining restaurant at 89 th floor. There are easy navigation signs that help the visitor through the attraction, from the entrance to the building up to the 88 th floor. There are maps of the path with ââ¬ËYou are hereââ¬â¢ sign at every point of stop for the visitors, however, the signboards are all written in English. Eureka Skydeck offers excellent opportunities for the schools to celebrate different educational events, such as, teacherââ¬â¢s day, education week, childrenââ¬â¢s day etc. and many more excursions. The schools are offered guided tours at no additional cost if they book during the offers, free entry to the teachers upon showing the VIT card during teacherââ¬â¢s day promotions. The visitor information can be found in the website (Eureka Skydeck 2018). Guides are available for the guided tours only. People mostly prefer to go on a self guided tour and spend time as their own. In case of education excursions and tourists, with difficulty in English, can opt for guided tours. The tourists can avail the audio aid with headphones for audio tour. There brochures and guide books about the Skydeck are available at the entrance of the tower, ticket counters and at the 88 th floor. However, apart from the ââ¬ËSerendipityââ¬â¢ touchtable, there are no touch screens for interactions throughout the path to the deck (Eureka Skydeck 2018). The visitors have the option to pick a headphone and walkman to get an audio visual experience of the tour. The AV experience depicts the view points at every angle along with the audio of the history of the construction of the tower and contemporary Melbourne life, some fun facts and trivia (lookear.net.au 2018). Through the interactive AV structure and scripts are also present in the 6 meter long ââ¬ËSerendipityââ¬â¢ touchtable presenting less well known facts of the city. Eureka Skydeck offers a 360 degree breathtaking view of the Melbourne city, especially, the Port Phillip Bay, Melbourneââ¬â¢s CBD and Dandenong Ranges through thirty view finders on the observation deck in 88 th floor of the Eureka Tower. It is open daily from 10 in the morning to 10 in the night. Sunset and the evening are the most favored time of the visitors (tripadvisor.in 2018). Apart from the deck, the Edge is also another favorite of the tourists. Eureka has introduced another visitor experience, Eureka Vertigo, where it presents to the visitors an illusion of loosing balance and falling from the 88 th floor at the extra cost of AUD 15. The elevator takes only 38 seconds to reach the deck (tripadvisor.in 2018). The open-air terrace gives a feel of the strong wind and people get the sensation of hanging midair in the Edge. Although it is a ticketed attraction, people prefer to visit the Skydeck to get an extraordinary experience of the magnificent view of the city. As stated by Swarbrooke & Horner (2004), tourists are motivated to visit a place due to the push and pull factors and personality of the tourists is a determining factor for motivation, perceptions and the tourist behavior. Skydeck is preferred by the tourists who are motivated by the features of the Eureka Skydeck and the uniqueness of the experience that it gives. According to the travel-motivation theory by Gray (1979), the consumers choose the travel destination based on the two motives, one is to travel from a known place to unknown place, known as the ââ¬ËWanderlustââ¬â¢ and the other is to travel with a specific purpose to avail some facilities not available at the residential place, known as ââ¬ËSunlustââ¬â¢. These are the mostly the recreational, pleasure, cultural experience, shopping and new experiences (Chen and Chen 2015). In case of the Eureka Skydeck, people come here to have new experience, following the ââ¬Ësunlustââ¬â¢ motivation. It can be said that, people love to visit the Eureka Skydeck in the Southbank of Melbourne to get the best view of the city from the tallest observation deck in the Southern Hemisphere. At a minimum cost, the tourists want to get a unique experience, which reflects the motivation of sunlust as well as due to the push and pull factors of the Skydeck. Eureka Skydeck is a must see attraction of Melbourne that provides all the modern facilities to the tourists apart from the marvelous view of the city. From gifts to dining experience, Eureka Vertigo and the Edge are the additional factors that drive the tourists to the Skydeck and make an incredible memory for the lifetime.

The advantages and disavantages of being a military mother Research Paper
The advantages and disavantages of being a military mother - Research Paper Example Greater effort to gain the respect of her male colleagues D. Tendency not to forget the emotional trauma of war E. Limited freedom V. Conclusion VI. References The Advantages and Disadvantages of Being a Military Mother Which is worse ââ¬â a male soldier urinating or a female soldier breastfeeding her two babies at the same time with her breasts fully exposed to her colleagues? Although everyone is entitled to his or her own opinion, there is a good chance that most people would think that the latter scenario is worse. There is definitely nothing wrong with women breastfeeding nor with women becoming soldiers, but it is simply too uncomfortable to see these female soldiers breastfeeding. Military mothers, just like any ordinary soldier, have served their own countries well, with even around 30,000 of them in the U. S. Army sent to Iraq and Afghanistan (Scott, 2010). Nevertheless, despite the honor of fighting for their country, military mothers face a whole lot of disadvantages t hat would have to make them either become more steadfast in their military duties or return to a more peaceful life as a civilian mother. Basically, the advantages of being a military mother are simply the benefits that a soldier receives. Military mothers are not treated differently from male servicemen just because they are female. One of the advantages of being a military mother is that they can avail of the usual benefits conferred to all members of the military. This includes relocation assistance services, money management services, family advocacy services, legal assistance services, deployment services, and child and youth services. Just like any serviceman, a military mother avails of relocation assistance services like briefings on how to adapt to transfers. Money management services consist of programs for the education and counseling of soldiers including military mothers on how to handle their finances, how to eliminate debt and how to spend their money wisely, whether or not on active duty. Family advocacy services refer to parent support groups that hold abuse prevention classes and at the same time provide assistance to families of soldiers and military mothers as well as those families with special needs. Legal assistance services are those that offer walk-in services for soldiers and military mothers as well when they need advice on personal legal matters, filing of income tax, preparation of wills, contracts, correspondence and other legal documents. Deployment services refer to briefings on how to manage new household budgets while military mothers are away from their children, how to maintain communication with the family, and how to prepare wills in case death occurs while the military mother is on active duty. Lastly, child and youth services are all about child care programs for soldiers including military mothers. These programs include sports and fitness programs as well as trainings on leadership, arts and recreation, as well as ment oring and education of young children. School transition support and outreach programs are also provided to the children of all soldiers. Most of these services are available to soldiers and military mothers through the Army Morale, Welfare and Recreation program of the government, where recreation, sports, travel, leisure and entertainment

Formal Business Report - Essay Example imarily taken as benchmark because it is one of the biggest success stories within the fashion industries that have been able to retain its competitive edge even in the tough economic conditions. The firm, ABCD Fashions is recommended to follow the model of Zara and expand its operations globally, especially in emerging economies like India, China. The consultancy report is prepared by the Marketing Manager for the Board members of UK based fashion retailer, ABCD, on the potential of expanding the business across the globe. The major purpose is to recommend the best way to proceed over the next three years in the current competitive business environment. ABCD Fashion is a high-end UK garment retailer which is facing huge competition from domestic and foreign apparel houses. While Primark and Tesco attract customers with their low cost fashion garments, Mark & Spencer, Zara etc. offer a wide range of high-end garments which become very attractive for customers during discount seasons. Today, contemporary fashion is more influenced by the changing socio-cultural paradigms of rapid globalisation and the myriad channels of communication such as the Internet, international magazines, TV etc. have evolved as crucial tools that facilitate greater awareness regarding the changing fashion trend across the customers. Moreover, lack of variety in fashion clothing, problems of cultural biases faced by retailers and the recessive trend in the economy have significantly impacted the performance of the firm and the industry in general. The company therefore, needs to evolve innovative strategy and creative input within its operations to identify a nd exploit new opportunities of growth. Another similar business, Zara, a member of the Inditex group of Spain, was studied and used to compare and contrast the business imperatives vis-Ã -vis Strategic orientation towards product-market development; competitive strategy pursued; product innovation; technological innovation; and

Countermeasures to Automobile-Exhaust Pollution Essay Example for Free
Countermeasures to Automobile-Exhaust Pollution Essay The world motor vehicle population exceeds 1 billion units at the moment. These vehicles are used for transportation of people and products across various places around the world. As a result, they emit many pollutants. This is attributable to the action of their engines burning fuel to release energy, which is an inefficient process. Firstly, they release particulate matter consisting of both organic and inorganic substances into the atmosphere, through exhaust emissions. Secondly, they release Volatile Organic Compounds (VOCs), which have carcinogenic effects. Pollution from vehicles is a universally acknowledged problem. However, it varies depending on the nation and its population. For example, pollution from cars contributes to between 50 to 90 percent of the total in urban areas. This may not be the same for rural areas. However, motor vehicles still present a disadvantage to the environment and human life. It is, therefore, prudent to develop countermeasures to automobile-exhaust pollution. Most of the worldââ¬â¢s vehicles are operated on conventional hydrocarbons such as diesel and gasoline. By switching to fuel that maintains less pollution, the environmental impact of vehicles can be minimized. An alternative fuel technology that has the potential to meet this challenge is fuel cells. In this technology, hydrogen has maintained the best promise as a candidate to replace petroleum-based fuels. This technology utilizes hydrogen gas to create electricity. This electrical energy is converted to mechanical energy through an electric motor, which makes the wheels of an automobile to rotate. In this process, the emissions developed are pure water, Carbon (IV) Oxide and various oxides of nitrogen. This emissions are attributable to difficulties in storage and commercial production. Despite the release of oxides of carbon and nitrogen into the air, hydrogen fuel cells have a smaller footprint on the environment, when compared to conventional gasoline engines. However, such inefficiencies can be eliminated through use of concrete, as researched by a study at the University of Eindhoven (Yirka npp). The easiest method for manufacturing hydrogen gas at the moment requires mining fossil fuels, which has an environmental impact in its own right. However, new production techniques such as bacteria and biomass waste are expected to become conventional in the coming years. This will reduce the environmental impact of fuel cells, since the technology will lower oxides released into the air (Katsuhiko 3371). A hydrogen fuel cell works by the introduction of hydrogen at the cathode and oxygen at the anode. In the process, water is released out. Anions and cations from the cell are harnessed at the respective terminals, and energy is released. Hydrogen has a high energy content of around 150MJ/Kg or 61,100 BTUs per pound. This exceeds gasoline and its 20,900 BTUs of energy per pound. High energy content implies that less fuel is required to maintain the same amount of power in engines, or to travel the same distances. Similarly, it has a higher efficiency when used in combustion engines. Advanced hybrid engines such as that of the Prius maintain an efficiency of about 40% (Potera 38). However, hydrogen has an efficiency of about 75% when used as the lone source of fuel. This efficiency means that greater distances can be covered with less consumption of energy. However, introduction of additional hydrogen fuel cell cars has been hampered by infrastructural issues. There are limited facilities that allow fuelling to conventional commuters within their localities (Katsuhiko 3369). There are many electric cars (EVs) on modern roads. Examples may be seen from Teslaââ¬â¢s roadster and the Nissan Leaf car. These vehicles release virtually no emissions to the environment, therefore are a solution to automobile-exhaust problems. This is attributable to their engines, which do not burn fossil fuels in order to release energy. Electric cars use sets of linked batteries as their primary source of energy. These energy sources comprise materials such as lithium, lead and nickel-metal hydrides. These batteries typically consist of thousands of cells such as the lithium-ion type. They store energy that has been harnessed from electrical outlets at home, or the recharging stations that are found in some major cities. In the example of the Model S, the vehicle is charged through a ââ¬Ëhigh power wall chargerââ¬â¢. This device is replenishes the batteries around twice as fast as conventional power outlet would manage. Electric batteries are used to operate everything in the vehicle. They are used to run a controller which serves to run an electric motor. This motor is what rotates the wheels in EVs. Through recent breakthroughs in manufacturing, EV batteries can be mass-produced. There are now lower costs of ownership and maintenance to the consumer, when compared to the past. Batteries have a very high energy density, when compared to fuel cells. As a result, they offer higher mileage than traditional fuels. The Tesla Model S provides a good example of mileage. It can manage about 300 miles of travel at a speed of 55 miles per hour, out of its lithium ion batteries. Even conventional lead-acid batteries allow a range of 80 miles. EVs are characterized by high torque and low speeds. They are, therefore, very useful for usage within cities, where many vehicles are located in smaller vicinities than rural areas. They will help in reducing urban pollution since they do not release exhaust into the environment. The production of EVs often has higher environmental pollution than conventional cars (Lave and Hendrickson et al. 993995). Improvements in production are needed for the solution of such issues. However, the usage of such vehicles is limited by infrastructural issues, just as the hydrogen fuel cells. As a result, the Environmental Protection Agency (EPA) has highlighted that only 4,000 EVs are currently running on American roads. This contrasts to gasoline-based vehicles which are in the millions. New breakthroughs in charging and fuel range are required for such EVs to gain critical mass of commuters. The larger the distance a vehicle is driven, the more pollutants it releases to the environment. According to the EPA, over one third of smog emissions are attributable to vehicle use in urban areas. However, more people have taken to the roads since the 1970s. Similarly, they have driven for longer miles hence attenuated the pollution problem. This has only served to attenuate the problem at hand. People usually drive for many reasons. Firstly, it may be as a means for arriving at work. Secondly, they do it to access leisure areas such as parks. Thirdly, they drive to shopping centers to do their groceries. There are ways that people can drive fewer miles while accomplishing all these needs. Firstly, they can involve themselves in carpools. This refers to the sharing of cars on journeys, between different people, such that several people drive in one car simultaneously. This is useful in that lower miles are collectively driven, hence reduced environmental pollution from exhausts. Through carpooling, people can get to work or leisurely places without inconveniences such as fuel costs, long drives and pollution. Carpooling is possible through websites, apps and pickup points. Use of public transport vehicles also achieves the same effect. People should use buses and other public transport means, whenever possible. Secondly, people can reduce the environmental footprint of their cars by combining errands into a single trip. This is especially useful in the case of families that own multiple cars. Instead of sending different people to pick up items needed by the family, one vehicle may be used to collect all these items. Shopping often requires the use of vehicles, since the luggage may be overbearing. In that respect, pollution can be reduced through use of the efficient e-commerce platforms such as Amazon. Individuals are able to meet their shopping needs while reducing their environmental footprint. The use of trucks for shipping goods is also useful since it allows collectively leaner environmental emissions when compared to many cars operated by shoppers. The internet has allowed various individuals to work at home. Similarly, it has enabled people to telecommute. It would, therefore, be environmentally beneficial if people used these tools instead of driving to work on each applicable day. These measures also reduce congestion in traffic. There will be fewer vehicles on the road, thus fewer delays that accumulate into environmental pollution through release of exhausts. In the modern world, settlement has been defined by work and educational opportunities. For example, people try to live as close to work as is comfortably possible. This has been attributable to efforts in reducing travel times, as well as associated fuel costs. According to the United States Census Bureau (npp), over 10 million Americans travel an hour each way to work. This has provided a challenge to the countryââ¬â¢s urban planners and engineers. There has been a trend in altering commuting patterns through development of areas that provide ââ¬Ëwalkable communitiesââ¬â¢. This concept implies areas that require less motorized movements in order to get around (Fullerton Gan 303). Through walkable communities, commuters would be able to reduce their environmental footprints as they get around. Residential, leisure, business and industries are developed in a common area such that people get to each point devoid of cars. Alongside reduction of pollution, the quality of life is also improved for people residing in such locations, since they are able to exercise. Through use of alternative fuels, environmental emissions can be reduced. However, arguably the best approach to reducing such wastes would be an alteration of driving habits. In that respect, an effective method for reducing both fuel consumption and environmental emission would be a reduction in vehicle idle time. When people sit in their cars while their engine runs, they release exhaust just as they were driving. This happens during conditions such as traffic among others. In that respect, it would be prudent if people learn to switch of their engines in such circumstances. Manufacturers should also implement the start-stop systems across a wider range of cars. This will allow engines to switch off, when the cars are stationary. By stepping on the gas pedal, vehicles are able to start their engines immediately. This reduces the annoyances associated by drivers to starting their engines again. Cars of the past featured inefficient engines. They released more particulate wastes into the environment, while consuming more fuel than contemporary variants. However, some of these cars are still in service today. Despite good maintenance, older vehicles become less efficient than their original state. . Drivers should be encouraged to drive newer vehicles. For example, modern cars such as the Prius offer nearly triple the efficiency of older cars, in terms of fuel consumption and environmental consumption. Newer cars also adhere to modern emission controls that are set by the EPA and other responsible bodies (Dennis-Parks 799). In the United States, public transportation policy has been left to local authorities in cities and towns. As a result, the country lacks a homogenized transportation system. Schedules for buses and trains have difficulties in being followed. These systems are also characterized by slow speeds of movement. This has created frustration among users, who view cars as efficient modes of transportation. Similarly, American culture has often painted a tainted picture on public transport systems. The car has been portrayed as a symbol of achievement. The converse has been applied for transport systems such as buses. The American Public Transport Association states that usage of public transportation results into savings of over 35 million metric tons of Carbon (IV) Oxide on an annual basis. By switching to public transport for the average American round trip of 20, miles daily, an individual is able to reduce their annual emissions by over 4,000 pounds (Fullerton Gan 303, 304). Going to work is one of the key reasons behind owning a car in the United States. In that respect, companies can make a significant contribution to the efforts against environmental pollution. Firstly, they can provide shuttle bus services to their employees. In that respect, they can purchase or hire buses that will pick up and drop off employees at designated points, on each work day. This will assist in reducing vehicle emissions due to ride sharing. This can be seen through Google, which operates shuttle services for its employees. Secondly, companies can post ride-share boards in their premises. This will allow employee who live close to each other to commute on a single vehicle, thus saving fuel and the environment. Some companies have also assisted employees through creation of car cooperatives. These are services that allow employees to rent cars from a set location. In return, the employees pay small fees for their use of the cars. Such systems are very useful for people working in inner city districts, who need cars only on a rare occasion. This encourages them to use public and shared transport, as opposed to personal vehicles. It is estimated that the global urban population will almost double by the mid-21st century. As a result, alternate means of transportation need to be crafted for the urban populations. The use of motorized vehicles will only result into further environmental pollution in such areas. Urban dwellers will consequently be exposed to poor health and effects such as smog. In that respect, local authorities need to establish policies that encourage non-motorized commuting. Bike sharing programs are similar to car cooperatives, only that they are not characterized by polluting effects (Fullerton Gan 301). Different cities have made attempts at bike sharing programs. However, they are not meant to eliminate the use of motorized transport completely. Public transport and cars is used for commuting to centralized locations, where bicycles can then be accessed for movement within urban areas. Errands that exist within a radius of one mile are practical by foot. Similarly, bikes are useful for errands within five miles, which characterizes the inner city. Various cities around the world have embraced such measures. For example, the Chinese cities of Beijing and Shanghai have bike sharing programs that have operated very well. Cities may also embrace some measures, which may be rather draconian. For example, cars whose registration ends with odd numbers may be allowed access to roads on particular days of the week. This measure will allow a curtailment of excessive vehicles on roads. Similarly, it will encourage ride sharing programs. Cars have an impact on environmental pollution, especially in the urban context. In that respect, several measures can be observed, in the efforts of reducing exhaust emissions. New technologies such as hydrogen fuel cells and EVs will be useful in reducing emissions such as the oxides of carbon and nitrogen. However, of greater use is the adoption of efficient driving habits by commuters. Car manufacturers also have a role in the reduction of emissions. By rolling out start-stop technology to all cars, high environmental savings can be recorded. Driving to work is an important part of many American lives. Companies can assist in environmental efforts by providing their workers with ride sharing and shuttle facilities. Companies such as Google and Apple present a good example of how this can be implemented. Similarly, local authorities and urban planners have an important role in designing cities that will require little use of motorized vehicles. Through implementation of such measures, massive savings on environmental pollutants can be recorded. Works Cited Dennis-Parks, Reda M. Instructing the EPA How to Regulate Vehicle Emmissions.

Greek Women in The Odyssey :: Homer
The women in The Odyssey are a fair representation of women in ancient Greek culture. In his work, Homer brings forth women of different prestige. First there are the goddesses, then Penelope, and lastly the servant girls. Each of the three factions forms an important part of The Odyssey and helps us look into what women were like in ancient Greece. The role that the housemaids play in The Odyssey is that of servitude. They are expected to serve the suitors and put up with their rude demeanor. During the course of the ten years that the suitors are there, many of the housemaids sleep with them. Upon returning to Ithica, and slaughtering the suitors, Odysseus makes the housemaids who slept with the suitors clean up their dead bodies. After this he hangs them by the neck, with this gesture he indirectly calls them ââ¬Å"harlotsâ⬠. This indicates one of many feelings toward women of that time. Then there is Odysseusââ¬â¢ wife, Penelope. She is depicted as an individual. Homer makes her character appear as very clever and also very loyal. Never once during Odysseus twenty years of absence does she remarry. She tolerates the suitors in her home for ten years but never chooses, always with the hope that her first husband, Odysseus, will return. Homer also makes her seem clever when she gets all of the suitors to bring her gifts before she ââ¬Å"chooses oneâ⬠knowing that they are in a short supply of resources. In another instance he portrays her as clever in the way that she keeps the suitor away by weaving the tunic for Odysseus and secretly taking it apart every night. The role Penelope plays is very important because she is seen as a person, not a possession. Finally, there are the goddesses. They represent women in all their glory. They are very human-like in that they feel the same emotions like jealousy, anger, pride, revenge, excitement, joy, compassion, etc. The exception being that they have supernatural powers. Homer even makes then human-like to the extent that they fall in love with mortals, for instance Calypso.
