Chinese Exclusion Act of 1882 Essay Example | Topics and Well Written Essays - 2500 words

Chinese Exclusion Act of 1882 - Essay Example These revisions ensured that the US could stop Chinese immigration and that this ban would last for 10 years. This law was later repealed in 1943. However despite such repeal, the act already implemented policies and set a precedent on the appropriate actions and attitudes which could be taken against the Chinese. This paper shall discuss the Chinese Exclusion Act has become the starting point and how it has resulted to decades of anti-Chinese sentiment. This paper is being carried out in order to establish a clear and comprehensive understanding of the implications and the impact of the Chinese Exclusion Act and how it has managed to continue to bear impact on the current attitudes and perceptions of Americans against the Chinese. Due to the California Gold Rush which lasted from 1848 to 1855, Chinese immigration to America started and this continued with the building of the first railroad systems (Kanazawa 780). In the early years of the Gold Rush where there was plenty of surface gold, tolerance for the Chinese was relatively high. In fact, because they were hard and persevering workers, they were easily accepted. However, as gold became harder to find and competition also increased, the tolerance for the Chinese and other foreigners was significantly decreased (Liu 152). At one point, many of them were even forcefully removed from the mines. These Chinese later settled in groups in various California cities, including San Francisco, taking in all sorts of odd jobs like laundry and working restaurants (Liu153). As a decline in the economy became apparent at the end of the Civil War, anti-Chinese sentiments became political issues raised by labor leader Denis Kearney and by then California Governor John Bigler (Murphy 458). These politicians attributed blame for lower wages to the Chinese ‘coolies.’ The Supreme Order of Caucasians which was a nationwide organization was also active in its anti-Chinese sentiments (Tian). As a result of the tension in the US involving the Chinese, the 1882 Chinese Exclusion Act was passed. This Act posed a restriction on free immigration into the US, and the specific target of this restriction was the Chinese. This act specifically mandated that skilled and unskilled Chinese laborers involved in mining were barred from entering the US for ten years; and if found guilty, they would be imprisoned and deported (Kanazawa 779). This act did not lead to the restriction of the Chinese immigrants into the US, however, it also led to various incidents of violence against them. Those who wanted to immigrate into the US had to ask for their government’s certification that they were indeed qualified to immigrate and this permit was also difficult to avail from their government (Kanazawa 780). This Exclusion Act provided the seed for other Chinese exclusionary laws in the US (Volpp). This act did not just impact on the Chinese people, but also on other Asians who were already in the US. For Chinese already in the US, they had to go back to China and obtain certifications. This act made the Chinese permanent aliens who could also not seek American citizenship (Volpp). After the act was passed, the Chinese men in the US did not have much chance of reuniting with the families or of even starting new families in the US. The amendments in 1884 provided further changes; these changes allowed those who were already immigrants to leave and then return. It also clarified that the act was applicable to

Concussions Case Study Essay Example for Free

Concussions Case Study Essay With all the excitement sports in our country and even around the world bring, some horrific injuries occur due to the competiveness of each participant. The human body can only take so much, and seems like a big target when competition is involved between two or more teams. An injury that has evolved the most out of all the injuries that can occur to someone is the concussion. According to the National Athletic Trainers Association and the National Collegiate Athletic Association, concussions in athletes is becoming the most common injury found compared to some other sports related injury. In the past, if you got hit in the head really hard you went out till your headache went away then you went back in the game. Nobody back then realized how much damage that hard hit to the head really did to you, or how long you should stay out for and recover. Due to advances in technology we now realize our philosophy â€Å"rub some dirt on it† or â€Å"shake it off† especially when it comes to head injuries is something you should never do. Due to improvements in technology and our scientist we are starting to realize and go deeper into how severe a concussion is or traumatic brain injury (TBI). By definition, a concussion occurs when there is a rapid acceleration or deceleration of the head. The brain moves or rotates inside the skull and different parts of it move against each other. Symptoms include headaches, confusion, amnesia and sensitivity to light or noise and can last days, weeks or months. According to the article â€Å"The Science of Hard Knocks† when this mild to severe blow to the head occurs what happens is the brain jiggles inside of the skull reorganizing blood flow. This causes no physical symptoms you can see so doctors can only depend on the information the athlete tells them. This is a huge problem because athletes being as competitive as they are, they may get cleared to play again and still have a concussion. According to the article â€Å"The Science of Hard Knocks†, A ton of concussions are being missed. And a ton of people are being allowed to go back not having fully recovered, says Robert Cantu, a concussion expert and chairman of the department of surgery at Emerson Hospital. Due to this some rules in and restrictions have been put in place by the NCAA on concussions that every head coach and athletic trainer must follow, but the main rule is if an athlete even shows the slightest sign of having a concussion they must sit out the for the entire event and must sit out at least a week before returning. Not only has this rule decreased the number of concussions but it has given the opportunity for athletes to recover fully from a concussion. There is really only one way to treat a concussion, the article â€Å"The Science of hard knocks† states that the only accepted treatment right now for a concussion is to rest the brain. This means no contact sports, no exercise, and no strenuous thinking, all in which are very difficult for your typical college athlete not to do. A big thing that many scientist and neurologist are studying now is the differences concussions have on men vs. women. The number of women participating in sports grew from 1.9 million to 3.2 million between 1990 and 2010. With an increase of participation in sports comes an increase in injuries, including concussion, and a need to understand its effects. Evidence is mounting that women, who are more likely than men to suffer a sports-related concussion, also have more severe symptoms in the days immediately fol lowing the injury. Though men go through a series of big hits, especially in the National Hockey League who is under intense pressure to come up with rule changes to reduce the number of concussions, also known as mild traumatic brain injuries, which have been linked to dementia later in life, studies show that men are less prone to get a concussion because of how long men have been playing sports and hitting our head. According to Dave Elemberrg within the past 100 years, our bodies and brains have adapted to the big hits. But, because women are so new to sports, women are three times more likely than men to suffer a sports-related concussion, says Tracey Covassin, a Canadian researcher at Michigan State University. The reason why women seem to get more concussion than men is not because they are less athletic Covassin says, but because she suspects that female athletes are getting more concussions because they are stronger, faster and more aggressive than in the past. â€Å"Women are also more likel y to be honest about their symptoms, she says, since unlike their male counterparts, they  dont risk losing lucrative professional contracts if they are injured.† Concussions have been overlooked by many people for a very long time. Because of this, some athletes have paid the price and now have to live with the consequences of not letting a traumatic brain injury heal properly. Due to our improvements in technology, rules and regulations set by the NCAA on this issue, and hard work done by scientist and neurologist we now have a better grasp on how serious a concussion or, a traumatic brain injury can be. It is safe to say that there is need for a more widespread understanding of the potentially dangerous impart of concussions in sports

Anti-Corrosion in Marine Surface Engineering

Anti-Corrosion in Marine Surface Engineering Surface Engineering: Coatings and Thin Films Technologies INTRODUCTION Surface building alludes to an extensive variety of advancements that plan to outline and change the surface properties of parts. There are two fundamental classes of surface designing techniques that can be utilized to advance the surface properties and the mass materials. These are surface coatings and surface Modifications. Other process include Surface shape design. Surface covering forms include protecting a layer of liquid, semi-liquid or substance material onto a substrate. One of the fundamental elements of surface covering is to change and fortify the surface capacities as opposed to improving the arrangement of the mass material. A few cases of surface covering forms incorporate Physical Vapour Deposition (PVD), Concoction Vapour Deposition (CVD), plasma and warm splashing, sol-gel, cladding and electroplating. Surface modifications procedures can be named solidifying by fire, acceptance, laser or electron bar, high vitality medications, e.g. particle implantation; and dispersion medicines, e.g. carburizing and Nitriding. Surface adjustment procedures are relevant to control rubbing, enhance surface wear and consumption resistance, and change the physical or mechanical properties of the part. Surface alteration medications additionally can be consolidated with surface covering forms, for example laser cladding. This blend improves the bene fits of surface coatings and surface adjustment, consequently accomplishing particular prerequisites and wellness for reason. Surface medicines that cause microstructure changes in the bulk material incorporate warming and cooling/extinguishing through acceptance, fire, laser, and electron bar strategies, or mechanical medications (one illustration is icy working). Surface medicines that modify the science of a surface incorporate carburizing, Nitriding, Carbo-Nitriding, Nitro carburizing, boriding, siliconizing, chromizing and aluminizing Hard facing is another type of surface treatment, where the mass material surface is given a defensive layer of another material having more predominant properties than those of the mass material. An example of this is covering a turbine pump seal joint with a destructive resistive material, to keep salty water from disintegrating the pump. Each strategy for hard confronting, cases of which are covering affidavit, cladding or welding, causes specific physical and concoction impacts on the mass material, some advantageous, some adverse. For instance focuses on which may exist in the defensive material can make issues, however watchful checking and research may restrain these impacts, to ideally create quality, serviceable building parts. The accompanying areas will portray the idea of surface building and the impacts designing situations have on these surfaces. Hard confronting procedures are portrayed in details particularly as to covering statement advances, with specific accentuati on on warm splash strategies, including the HVOF (High Velocity Oxy-Fuel) prepare that utilized as a part of the ebb and flow inquire about. 1.1 Surface Engineering At the point when two surfaces come into contact and relative movement is created, the contact stresses increased because of the generally little rate of load-supporting region. This will result in grating and wear, and potentially even prompt to disappointment. In the high anxiety utilizations of a present day motor or gearbox, there are zones where the weight of metal moving against metal powers away all the greasing up oil and permits warmth to develop. In the instance of extraordinary weight and contact, this warmth is sufficient to momentarily weld the two sections together just before they are broken separated by their development. This consistent weld and break handle which can happen at the nuclear scale bring about drag and wear, which are damaging. On the off chances that the riggings are the parts of a shuttle, and if the single part comes up short, the whole multi-million dollar shuttle would fizzle. So designed surfaces to battle grating and diminish wear is exceedingly alluring. Many materials have been developed to have specific bulk properties, although they have not been particularly optimized for the surface properties. Surface engineering can solve these problems by: Implanting alloying atoms to different depths, thereby improving toughness and fatigue properties; (surface modification) Depositing surface layers, thick or thin, including lubricants; (surface coating) Redesigning the surface shape of the component to distribute stresses. 1.2 Friction, Corrosion, wear Surface engineering techniques solve friction, corrosion, and wear problems. Friction, corrosion and wear are the most common factors that cause engineering failures. In industrialized countries, 7% of GNP represents the cost of friction, wear and corrosion, with the possibility of 1% of this figure being reduced through the use of efficient tribological systems. On a worldwide level, 34% of all lubricants produced are consumed in Europe, with 50% of this being recycled, with a further 2.5 million tonnes being lost in the environment. Corrosion is mainly an electrochemical phenomenon which occurs when metals react with materials in their environment. 1.3 Basic types of Corrosion and wear Fig. 1: Type of corrosion and wear Wear is the dynamic loss of material from a surface. Among the distinctive sorts of wear, rough wear and glue wear ordinarily happen more frequently than others. Grating wear is because of hard particles or hard bulges constrained against and moving along a strong surface. Cement wear is created by restricted holding between reaching strong surfaces prompting to material exchange between the two surfaces or the misfortune from either surface. Cement wear is a run of the mill case of how a delicate material can wear out a harder on. 1.4 Surface Engineering in Marine applications Methods of corrosion protection are based on the theory of corrosion processes. Alterations of the material properties and external environmental characteristics are the factors which can affect the slowing down or stopping of the corrosion process. Corrosion protection in the shipbuilding industry is an important technological process devised to protect the ship from corrosion effects. Even the storage area of plates, profiles and flats in a shipyard exposed to severe environmental conditions. Protection Coating in shipbuilding constitutes of following steps: Preparation of surface Temporary protection workshop Terms of coating Methods of Applying coating 1.5 Preparation of Surface Surface arrangement is a requesting innovative operation in the advancement of the ships body from essential surface readiness of plates, profiles, and pads performed in the programmed establishment .It likewise incorporates a fundamental workshop technique called covering. Shop groundwork in the film thickness 15-25 ÃŽÂ ¼m is utilized for the assurance of steel during the time spent ship development. In any case, compulsory control of the thickness of the coatings for more prominent thickness may unfavourably influence the cutting pace and nature of steel, and in addition the event of mistakes in welding. Optional surface planning is done in the corridors for sand impacting and painting, whereby soil and salt ought to be expelled from the surface of the area, rendering it and sandblasting as per standard ISO 8501-1. This innovative operation infers additional work in welding and crushing and speaks to the pre-gathering attachments. 1.5.1 Temporary protection of surface The principal phase of consumption assurance in the shipbuilding business comprises of the workshop covering (shop groundwork) on the plating profile and pads in a thin film, about of 15 to 25ÃŽÂ ¼m thick, as intemperate film thickness may adversely influence the nature of welding (the event of porosity) and cutting steel. Shop preliminary speaks to quick drying coatings which are utilized for transitory security of steel in the workshop amid ship development and utilization of the last covering framework. Transitory erosion security is performed in the workshop of preparing in mechanized plant beginning from drying sheets, shot impacting and covering as indicated by the ISO standard. Workshop coatings utilized are zinc silicate and epoxy press oxide shop preliminary. Epoxy press oxide is connected to acquire a more prominent thickness, requesting more paint, thusly bringing about higher coats and expanded misfortunes. Today in many shipyards zinc silicate is utilized as shop preliminary (with a share of 25-35 % zinc), which gives a superior quality welding and lessened event of undesirable zinc salts (a compound barely solvent in water and hard to clean from the surface) Shop preliminary must meet the accompanying prerequisites: It should be appropriate for mechanized re-coloring methodology, It have the most limited drying time (3 to 5 minutes), Imperviousness to high temperatures, It shouldnt discharge dangerous gasses amid welding and cutting, It shouldnt adversely influence the welding procedure It should not influence the mechanical properties of welded joints. 1.5.2 Terms of coating Surface readiness principles incorporate a few criteria, tenets and rules for the way toward get ready body metal surfaces. Surface states of steel structures are isolated into four phases: Steel surfaces secured with plant scale and little erosion, Steel surfaces, which have started to erode and from which process scale has begun to peel Steel surface displaying particles of rust or inadequately connected worrying factory scale with the main noticeable sings of setting, Steel surface that is unmistakably consumed and influenced by setting. The way towards planning metal surfaces done by different methods for abrasives. Abrasives are distinctive sorts of materials appropriate for the specific coarseness surface readiness, where the grating particles utilizing packed air are connected to the surface which is to be cleaned. 1.5.3 Method of Applying Coating The innovative procedure of erosion security utilizes diverse techniques for applying coatings by brush, roller or showering (air or airless), where the determination of the methodology influences the speed and nature of works. Paint brush is normally utilized for the methodology touch-up in the insurance of zones, for example, joints, moves, edges, welds and other unpleasant surfaces and setting. In these regions, color entrance is accomplished by applying the correct brushes: it cannot be accomplished by whatever other technique. Paint roller is seldom utilized in light of its deformities, arrangement of little uneven layers, more often than not with little crevices and openings. Applying a covering by splashing depends on scattering the paint as small beads that settle on the working parts. Airless splashing is a strategy that is most basic in the shipbuilding business since it empowers quick use of Paint onto extensive surface, high effect, the likelihood of applying thicker layer, and Great infiltration. ARC SPRAYING PROCESS Thermal spraying method is a process of coating in which a heated material is sprayed on its surface. This type of spraying can provide thick coatings over a large area at high deposition rate. Thermal spraying is classified into Plasma, Wire arc, Flame, Detonation, Warm and cold spraying. 2.1 Overview of Arc spraying process In electric arc spray process, two wires of desired materials act as electrodes are fed to spray gun at controlled feed rate. Compressed gas is also used to atomize and propel the material to the substrate. Fig.2: Schematic diagram of Wire arc spray device In this process, the anode and cathode wires are continuously melted and broken down into tiny droplets which are injected by air jets through a nozzle. The velocity of gas is a few hundreds of m/s but the gas is not heated, allowing operator to keep the substrate temperature below a few 0C without cooling. The arc powers generally range from 2 to 10 KW, airflow ranges from 0.8 to3 m3/min. The temperature of the arc can be as high as 20,000 k. DC generators are used a source for power. Before the arc process is performed, substrate surface is properly cleaned. For this purpose usually the surface is blasted using a compressed air abrasive blasting. This is effective for cleaning mill scaled on steel surface by using abrasive particle at high velocity and also for good adhesion of arc spray process. Along with this the substrate surface roughness is also important consideration to be made for proper coating bonding. To hinder rust formation and provide good bonding the coarse surface profile must be around 110 microns. Garnet is normally used abrasive as it can provide desired surface finish and roughness. As metallic abrasive usually result in energy being given off as a spark which might cause surface defect non -metallic abrasives are used. Fig.3: Arc spray process instrument Before the coating is applied on the substrate surface some conditions need to be satisfied, they are Surface finish must be greater than SA 2.5 as it can be visually inspected Surface roughness must range between 75 microns to 110 microns Permissible level for salt contamination of surface should not exceed 20 mg/m3 Dust level should not exceed the rating 1 2.2 Characteristics of Arc spray process Wire diameter: The wire diameter ranges from 1.6mm to 3.16mm. The deposition rate of coating on the surface depends on the wire diameter. Wire feed rate: This determines the rate at which the material must be introduced to the system, which is proportional to the rate at which the material introduced melts. Coating materials: Metals, cements, ceramics, polymers, carbides are some of the materials used for arc spray process. Solid wires produced from Chromium, zinc nickel based alloys or aluminum are generally used for arc spraying in marine application. Aluminum is considered to have the best performance for surface coating. Spray distance: The distance varies from 15cm to 25cm; the distance affects the deposition area of coating on the surface. Power requirement: Depending on the spraying material, voltage ranges from 16 V to 30 V. The applied voltage controls the input power to the arc which affects the rate at which the tips of the wires are heated and melted. The current is adjusted to 150 A for most of the applications. 2.3 APPLICATION OF ARC SPRAY PROCESS This process is mainly used for corrosion protection. Other than this, it is also applied for coatings of machineries like boiler tube, gear box, shafts and crankshafts in power plants. 2.4 ADVANTAGES AND DISADVANTAGES 2.4.1 Advantages Arc spraying process is economical when compared with other spraying techniques Any coating material can be used. Examples are ceramics, cement metals It has a high deposition rate of the thermal processes Operator requires less training The power requirement is also low Almost all substrate material can be coated Low porosity level can be achieved using this process Its useful as low heating of substrate makes arc spraying process useful in metalizing thermally sensitive substrate 2.4.2 Disadvantages Large amount of fume and dust is produced, which is a cause of concern for the operators health The materials used are limited to electrical conduction It can be sometimes seen that the coating quality does not meet to expectations as done with other technique 3. HOT DIP GALVANIZING 3.1 Overview of Hot Dip Galvanizing This process is used for coating iron an steel with a layer of Zinc by immersing the metal in molten zinc bath at a temperature of about 449 oC. This process forms a metallurgical bond between steel and molten Zinc and is done in a plant with controlled conditions. The bond formed has very good corrosion resistance due to the good molecular adhesion and the cathodic protection. The hot dip galvanization process mainly consists of 4 stages. Surface Preparation Removing oil/grease, dirt, paint etc. from the surface. Pickling in Acid To remove mill/scale. Flux Coating (Usually Zinc Ammonium Chloride) To prevent the oxidation of cleaned surface when exposed to air. Zinc Bath Dipping the material in Zinc bath and holding it until it reaches equilibrium with the bath temperature. Fig.4: Various steps in hot dip galvanizing method In HDG coating, the outermost layer (ETA) is a covering of pure zinc and is formed as the material is withdrawn from the molten Zinc bath. The underlying series of layers (of coating) are zinc-iron alloys and are formed as a result of metallurgical reaction between the molten zinc and the material being galvanized. In HDG process, the coating formed on the corners and edges of the material is generally thicker than the surrounding coating. The reason for this is that the zinc-iron alloys formed would grow perpendicular to the steel surface. The ETA layer is ductile and provides good impact resistance to the galvanized material. The combination of all the layers in the coating provides toughness to the material and also aids in resistance to mechanical damage in transport, erection and service of the components. Fig. 5: Typical cross section of a hot dip galvanized coating 3.2 Variable Parameters The appearance and the thickness of the galvanized coating are affected by several factors. Steel Composition: The galvanizing reaction produces thicker coatings for rough steel surfaces because of the increased surface area and also these coatings would have a poor appearance and would be a rough coating. Bath Immersion time: As galvanization is a diffusion process, the reaction between molten zinc and steel would be quick initially but slows down as the alloy layers grow and become thick. So, continuous immersion or dipping of the material more than once doesnt produce a significantly thicker coating. (Which happens in case of reactive steels) Speed of Withdrawal: The withdrawal rate of material from the galvanizing bath has a significant effect on the outermost layer of the pure zinc. Thickest coating would be formed when the withdrawal is rapid because this allows a large amount of zinc to be carried out on the material which would eventually solidify and become pure zinc layer. On contrary, smooth, thin and uniform coatings are formed with slower withdrawal rates as it allows the zinc to drain back into the kettle. Steel cooling Rate: The dull or matte gray coatings are usually due to slower cooling rates such as air cooling or quenching of thicker sections because the slow cooling would allow the zinc-iron alloying reaction to continue and the inner alloy layers would use the outer ETA layer for their zinc supply. The formation of dull/matte surfaces can be reduced by halting the galvanizing reaction by quickly reducing the temperature to less than 300oF. 3.3 ADVANTAGES AND DISADVANTAGES 3.3.1 Advantages Lower first cost: This process generally has the lowest first cost compared to any other protective coatings for steel. The application cost of painting which is a labor intensive coating has risen far more than the cost of factory applied hot dip galvanizing. Lower maintenance / lower long term cost: In some cases, the initial cost of hot-dip galvanizing is higher than alternative coatings, but it is more cost effective due to its lower maintenance costs during long service life. Maintenance is costlier for structures in remote areas. Maintenance programs have an invariably negative impact on productivity. Long Life:In hot dip galvanized coatings, the life expectancy of structural members is 50 years more than in more rural environments and 10 to 30 years in most corrosive urban and coastal environments. Surface preparation:To ensure uniform cleaning of steel surfaces,they must be immersed in acid whereas organic coatings must be applied on abrasive blast cleaned surfaces and should be verified by third party inspection. Adhesion: This coating is metallurgical bonded to the steel surface. Environment friendly:The coating is non toxic and doesnt contain any volatile substances. Speed of coating application:A full coating can be applied in minutes whereas multi paint coating system takes up to a week. The application of hot dip galvanized coating is not influenced by weather conditions. Uniform protection:Hot dip galvanized surfaces are protected both internally and externally including recesses, sharp corners and inaccessible areas for application of other coating methods. The coating is at least as thick over sharp corners as on flat surfaces. No other coating applied can provide similar uniform protection. Sacrificial protection for damaged areas:A hot dip galvanized coating would preferentially corrode to steel providing cathodic protection to small areas of steel exposed to damage. Toughness:A hot dip galvanized coating has outstanding resistance to mechanical damage during transport, erection and service due to its unique metallurgical structure. Disadvantages This process can only be carried out in a galvanizing plant and on site application is not possible. The color of the zinc coating can only be changed by painting the coated surface. The size of the zinc bath is a limiting factor for the component or structure dimensions. There is probability of distortion/warp of large flat unsupported sheet components and long, slender beams due to the high molten zinc temperature. The welding of the zinc coated steel would need different procedures as compared to the uncoated steel. During welding of hot-dip galvanized steel, there is a loss of coating in the first and second heat affected zones, but a portion of the coating remains right up to the edge of the weld. COMPARISON OF ARC SPRAY PROCESS AND HOT DIP GALVANIZING FOR COATING OF SHIP HULL As studied in the sections before both Arc Spray Process and Hot Dip Galvanizing has their advantages and disadvantages. In this section we will compare both these process based on important characteristics and try to find out which one would be a better suitable process for coating of ship hulls. 4.1 Surface Preparation Hot Dip Galvanizing requires specific surface preparation consisting of Degreasing, Pickling and in Flux solution, not only these surface preparation method requires special setup, but processes such as Pickling can introduce Hydrogen in the substrate causing Hydrogen embrittlement and Hydrogen Induced Cracking, however if the substrate steel is not cleaned properly the zinc will not bond with it and it may be noticed at that stage only. Surface preparation for Arc Spray requires the surface to be little coarse which can be done by abrasive air blasting which depends on the operators experience, but if the cleaning is not done properly it may not be detected then. Thus surface preparation by Hot Dip Galvanizing is advantageous. 4.2. Coverage Arc spray process cannot be used for coating of corners, edges and complex shapes such as threads and hollow section, all of which can be coated easily by hot dip galvanizing as it is a dip process. Since ship hulls are large bulky object which doesnt have any such complex shape both processes can be used here but still Hot Dip Galvanizing will be more beneficial. 4.3. Process Time and Economy Hot Dip Galvanizing takes less time as it can coat almost all the surface area at one go when dipped inside the bath whereas Arc spray process is a line by line process and hence takes more time. The equipment cost for arc spray is lower, its setup is also easier than Hot Dip Galvanizing, and the equipment is mobile whereas the baths for Hot Dip Galvanizing is stationary but this method can cover large area at one go. Therefore for coating of ship hull, Hot Dip Galvanizing is a faster process as they have a very large surface area for which Arc Spray process will take more time and the higher cost of Hot Dip Galvanizing is negated by ability to cover larger surface area at one goes. 4.4. Effect on Substrate For Hot Dip Galvanizing the baths are maintained at a temperature of around 450ÂÂ °C which is just below the austenitizing temperature of steel and hence may cause a change in microstructure of the substrate if there are some variations whereas since no hot jet is directed on the substrate in the arc spray process there is no effect on the underlying substrate. Thus only considering this effect on substrate thermal arc spray process is a better process. 4.5. Coating Thickness The thickness of coating in electric arc spray coating can be regulated by regulating the speed of wire feed in the process, thus it can be easily controlled whereas in Hot Dip Galvanizing a certain thickness may not be specified as the thickness depends on the withdrawal speed which may cause an uneven distributed coating. 4.6. Bond Strength The bond strength for arc spray process for ferrous and non ferrous alloys is within the range of 4000-7000 psi whereas for Hot Dip Galvanizing the bond strength is around 3600 psi, thus arc spray process provides comparatively higher bond strength. 4.7. Hazard Fumes and other hazardous by products are formed during the Hot Dip Galvanizing can pose health hazard to the operators who are working in the shop floor as well as to the environment. Thermal Arc Spray process on the other hand produces metallic dust consisting of very fine particles and fumes; also electric arc spray process operates at high current which can result in shock hazards if not treated with caution. Clearly both processes are hazardous both to human as well as environment. 4.8 Conclusion for comparison Considering all the above factors Hot Dip Galvanizing seems to a better and efficient process for coating of ship hulls, not only coating ship hulls which have large surface area by arc spray a time consuming task it doesnt providing any other significant advantages as compared to Hot Dip Galvanizing. CONCLUSION In this report, we have mentioned the different possibilities for anti-corrosion in marine environment. Here we have taken the two commonly used methods for the protection of ship hull from corrosion. As the instrument for arc spray process is quite cheaper compared to the other techniques, its widely used in marine industry. The coating adherence is good with no heating of the substrate generally; however coating done by this method is porous. The hot -dip galvanizing process is an effective way for resisting corrosion. It is a simple process with better service life. It gives high quality with low environmental pollution making it a good competitive method. After comparing the two methods, we can conclude that arc spray process is used if we want good control and for better quality, on the other hand hot-dip galvanizing is used for mass production as it turns to be economical. 6.

The Time Machine Essay -- essays research papers

The main characters in The Time Machine were The Time Traveler, Weena (an Eloi who The Time Traveler rescued), the Eloi as a race and the Morlocks as a race. Now that you know the main characters, I will explain their purpose in the novel and their behaviors. Weena was by far the most interesting character in the novel. She was an Eloi who was drowning while trying to bathe in a river. The Time Traveler quickly jumped into the river and rescued her. Weena then started following The Time Traveler everywhere during his explorations. He learned about the Eloi people and their language and the Morlocks from Weena. The Time Traveler was definitely intelligent. He figured out a way to travel through time! He was also a very charming, rich and friendly man, a little too anxious and curious, I would say. His anxiousness made him go to another time unprepared, nothing with him but a package of matches. The Morlocks are a futuristic equivalent to our current day primates-just uglier, smellier and they live underground. They are very aggressive and are blinded by even weak sources of light. The Morlocks are carnivorous and sometimes make a meal of an Eloi. The Eloi are a beautiful, friendly and fragile race of small creatures. They seem to have a great fear of the dark, because that is when the Morlocks come out from their Underworld. Both are descendents of humans. The Morlocks stole The Time Machine (I think) to lure The Time Traveler into the brass gates so they co...

Latin American Politics Essay

Hugo Rafael Chavez Frias is the current president of Venezuela and was born on 28th July, 1954. He is a leader who advocates for democratic socialism in his country and for Latin American Integration. He openly attacks the policy of globalization, neo-liberalism and opposes most of the foreign policies of the United States. The president is very popular and respected at home for he is able to keep the promises he made to his people for example to fight poverty, malnutrition, illiteracy and other related social ills that affected citizens. His personality and policies evoke a mixed reaction from different nations some in the Latin American region and others from abroad. Some support his ideologies while others criticize them and a good example is the United States government which refer him as a threat to the Latin America’s democracy. The reason behind this is that he tries to implement some modalities that would promote regional integration and cooperation among the Latin American nations and especially the Latin’s poor nations. This essay is going to look at how Venezuela’s foreign policies under the directions of Hugo Chavez have changed overtime. The paper will also give a brief overview of the life of Hugo Chavez and then proceed to discuss how his policies have benefited the Venezuelans back at home and affected other nations. The paper will be concluded with a recap of the key points that have been discussed. The last page of this paper is a list of the references that have been consulted, properly formatted in accordance with MLA style. After Chavez won in 2004’s referendum, he promised to uplift the living standards of his people under a program that was dubbed as â€Å"Bolivian missions† something that proved to be successful because it was favoured by the increase in oil prices. Through this, he was able to gather billion of dollars as foreign exchange which he used to boost his country’s economy which reached 9. 3 in 2005. (Painter) Venezuela’s economy mostly depends on the oil it produces. Since 1920 up to the present day, the profit that is accrued from oil exports has led to the growth and development of this nation more than one would have imagined for example the size of Caracas city doubled in the 1920-1936 period and tripled in 1940s. Despite the fact that the country exports a lot of oil to other nations, half of the population are very poor and live in slums and that is why Chavez has dedicated his efforts to eradicate poverty in his nation and to reduce the high rate of inequality that has continued to affect citizens. Currently half of the Venezuela’s population live in urban cities while the other half is in rural slums where they live in abject poverty (Mora and Hey 78) Chavez has always been trying to boost relations with other Latin Americans in a bid to achieve regional integration in fact this is one of his key foreign policies, a goal that he started to pursue after the 1997’s Summit of the Americas. Venezuela has been very vocal in advocating for the lifting of sanctions that have been imposed on Cuba and other ‘Multi polar’ ties that are imposed on other developing countries. Although Venezuela has not been enjoying warm relationship with United States, it has never experienced the military, political and economic sanctions that are imposed on other nation perhaps because of its oil producing capacity. (Painter J. ) Venezuela occupies a strategic position as far as the superpowers’ interests are concerned and the reason for this is that is supplies oil to these countries in large quantities something that made it to be ranked among the biggest oil producers in the world. Despite the fact that it was one of the primary oil suppliers to US and a role model to other Latin American nations US has never recognised the role it plays partly because of its aggressive foreign policies. Although U. S and Venezuela have not been good very friends, Venezuela continues to export oil to United States. Their relationship is from time to time affected by other factors and adding salt to the injury was the 2002’s attempted coup that led to the temporarily removal of Chavez from office with an assistance from US government something that US government denied. (Isbell) The reason why US sponsored this coup was that the Latin American oil producing countries were extending their business relations to Cuba contrary to what US would have liked. US wanted the sanctions it had imposed on Cuba to remain but its efforts were undermined by Chavez’s move to sell oil to Cuba in a bid to maximize his capital. For this reason US wanted Chavez to be removed and replaced with another one who would not interfere with the sanctions that had been imposed. Venezuela apart from starting business relations with Cuba it signed a business deal with it to increase its oil sale to Cuba something led US to deny Hugo Chavez a visa to go to its country. (Elliott) Venezuela in reaction to this started to openly oppose US policies especially after the 200’s coup attempt for example, Venezuela voted against US’ claims in the United Nations meeting that there were human rights violations in Iraq, Libya and Cuba. It also opposed the sanctions that were intended to be imposed on Peru in 2002 by the United States in respect to the agreement that was reached in Quebec’s summit. As if this was not enough, Venezuela criticised and opposed what US referred to as ‘Plan Colombia’ designed to fight the sale of narcotics in the region. The plan was to allow free antinarcotics over flights in the Latin American region, a move that was opposed because of its US military nature which was likely to cause regional conflict. (Mora and Hey 159) The US relations with Venezuela reached its worst point after the 2001 New York bombings. The US government had vowed that it would fight terrorism completely and war was waged against Afghanistan. The Venezuelan government criticised this move arguing that terrorism cannot be fought with terrorism. They shown pictures of young children who had been killed by US bombs. As their relations continued to worsen, the US government was trying to improve this relationship. The US even denied having participated in the 2002’s attempts to swap Chavez with Pedro Carmona. The only motivating factor for the United States to do this was to ensure that there was continued flow of the commodity they heavily relied on, the oil and that their power would be felt in the Latin America and especially by Fidel Castro. (Mora and Hey 155) Chavez was also been vibrant in rescuing the oil prices especially when they were on the decline in 1998. He liaised with other OPEC members and held a crisis meeting to solve the problem of the decline in oil prices. His efforts were duly paid because after this meeting the price per barrel shot up something that made his power to felt in the world. (Lotta) Although there is lot hegemony from the US government, Chavez has never allowed US government to take control over his country. He visited the OPEC countries in 1999 and specifically the Libyan and Iraq leaders Muammar Gaddafi and Saddam Hussein respectively in his trial to his business ties. In 2001 Chavez visited the Asian countries to share his support on communism both in Russia and China but this was not all that he wanted because for was trying to look for new business partners. Although he was doing this he never failed to acknowledge that though his country was at verbal war with US, it was its key oil supplier. It acknowledged this especially after it stopped to give oil subsidy to the Cuban government. (Elliot et al) In his move to improve and extend his country’s foreign policies to Asian and European countries, he killed the democracy that was enjoyed at home by Venezuela’s institutions. At the same time as democratic institutions declined, the warm relationship that had existed between other regional Latin countries was lost. His aggressive pursuance of foreign policies was counter productive as it made him forget the issues that needed immediate address back at home, â€Å"foreign policy did not contribute to the provision of adequate responses to the most urgent domestic economic and social needs† (Mora and Hey 160) Although he is criticised and demonized by many people, the way he has impacted this nation is much more than what other leaders had done. He is accused of perpetrating corruption but all in all, he is different from others in that his foreign policies have led to the increase in oil prices and to the improvement in living standards. He channelled more dollars on the fund that is used to help the less privileged in the society. Many argue that were it not for his ability to make oil prices rise he would not be in power. The argument is that Chavez can only remain in power if will be able to ensure that the price of oil will remain high. At the moment, Hugo Chavez is trying to look for new market for his oil in the Asian and western countries. This move is meant to expand Venezuela’s business relations while at the same time punishing US for pursuing aggressive goals towards it. Chavez according to Lotta R. (2007), â€Å"the third track of the oil program is to restructure Venezuela’s external trade relations away from dependence on the US as a market and source of investment capital and technical expertise. † Venezuela alone exports about 12% of petrol to United States and thus it contributes to the power that US exerts to the world. It is said that this is about half of its production and that is why it is looking for other buyers. Already the country is holding talks with Chinese and Russia governments to sell oil to them. It is also planning to sell oil to India but the problem is that Venezuela does not have its own port and is thus required to put a pipeline to pass through Columbia to china. Another problem is that China does not have money that is needed to refine Venezuela’s sulphur rich oil unlike in US where are special refineries meant for refining Venezuelan oil. Though most of foreign policies are economically focused, in 2005 he stopped buying arms from United States and looked for alternative sources, he started to buy them from Brazil Russia, Spain and China something that added strain to the relationship that had existed between Venezuela and US. He also asked all the US military personnel who were active in the service to move out Venezuela. Since he took power, the price of oil per barrel has risen from 10 US dollars to 78 US dollars. This figure would be more than this were it not for the fact that Venezuela’s oil is sold a bit cheaper due to its high percentage of sulphur impurities however, its oil has remained as competitive as that of other OPEC countries. The sharp increase in oil prices could largely be attributed to his success in politics for example, he was able to win the majority’s support. Chavez is trying to establish market for his oil in countries that are not in good relations with United States such as Iran, Russia and Belarus, â€Å"Chavez used every opportunity to disparage the United States and seek to forge solidarity with a number of states at odds with Washington† (Hanson). Political experts argue that unless Chavez devise new ways of maintaining high oil prices then his regime will soon come to an end. It is for this reason that he is trying to establish new markets. Experts see this move as a threat to the survival of US as a world power but this might not necessarily be true. These experts have mixed views on this for example, John Hopkins, a professor dismisses Chavez’s rhetoric as something insignificant while others warn that his move should not be underestimated as he has widespread support in Venezuela. In reality, Chavez is not a threat to US but all he wants is to widen his economic base and that is why he is having many trips across the world so that he would broker more economic cooperation among other oil producers. He is also trying to secure himself a seat in the United Nations Security Council a move that is vehemently opposed by the United States. In response, the US imposed some sanctions against Venezuela especially on arms importation citing the reason that Venezuela was not supportive on terrorism war. (Kozloff, 98) It is argued that if Venezuela would stop selling oil to US, oil price would shot up almost with at least 11 dollars per barrel. Some are underestimating his potential to become a world power but they should consider how the rise in oil prices in the last few months has made him popular both in his country and world wide. He used that money to foster his programs, to forge and to booster commercial ties with other nations. At the moment he (Chavez) is threatening that he would stop supplying U S with oil. (Kozloff, 99) In his foreign relations, Chavez advised other OPEC members to cut their supply so that the price of oil would increase. Although international flights to US were banned, he decided to drive from Iran to Iraq and as a result of this; the price of oil reached $25 per barrel in 2004 something different from how it was prior to this period and all this was happening when he was the president of OPEC. The upsurge in prices was also as a result of his efforts to look for other oil consumers and especially in the developed nations such as china, India and even Japan. These nations use a lot of oil leading to its shortage. To counter this move, the US government is referring him as a â€Å"negative force† and is even trying to urge Chavez neighbours to isolate him. (Elliot et al 26) The foreign policies of Hugo Chavez have greatly impacted on Venezuelans and the country at large. Chavez using the money that is got from increased oil prices to fulfil the promises that he made to his people under the mission he dubbed as Bolivian Mission. He has significantly improved the living standards of his people for example he reduced poverty, malnutrition and illiteracy. His foreign policies have been widely criticised by the western nations and more specifically the US particularly due to its move to extend its business relations to the Asian countries such as China and India and other Latin American nations that are not in good terms with US.

Finding Freedom: What it is and what it’s not Essay

Abstract Human freedom could very well be the most controversial topic in our society. To some, human freedom is the freedom to be educated, to work and provide financially for yourself and your family. The freedom to drive a motor vehicle. To vote for the president you truly believe in. To move about freely from one city, state, country or continent to another. In this report, I will investigate the perceived legitimacy of these freedoms, amongst others, and expose the variations in the definition of this word â€Å"freedom.† Finding freedom Many aspects of life come to mind when one is brought the question, â€Å"are you free?† The average person would say yes, they are. But, what does free actually mean? Most would say the ability to choose from any option dictating their personal future. But, there is a contingency to every decision we make and every freedom or option we have. We all want to make our own choices and decide which direction we want our life to go in, but that comes with a price. That price could very likely be one that we may not be willing to pay. Is that actually freedom? In order to take advantage of the freedom to drive an automobile, you must first pass a written test. Following the written test, you are required to pass a road test and pay the fees to become a licensed driver. Not to mention that you must have current insurance to even drive a vehicle after you’ve done all these things. With that said, you have the freedom to operate a motor vehicle, but you don’t have the fre edom to do so without first successfully completing the aforementioned steps. The United States boasts the fact that all of its citizens have the freedom to travel freely, both within and outside of its borders. Of course there is a contingency. They must know where you are going and for how long as well as other information one probably wouldn’t offer it that were not required to exercise their â€Å"freedom.† Describing human freedom is problematic at best as most see simply as the ability to do what you want. Jerry A. Coyne (2012) Stated that while people do have the ability to do what they want, what they want is predetermined by laws just like the laws of physics. In that sense, our so-called freedom is already within certain boundaries. Not realizing this, it’s even harder to understand that we already exercise our freedom within boundaries of the natural boundaries that have already existed. Finding freedom The idea of human freedom fits into the field of sociology though the fact that ones personal idea of being free directly results in the decisions that person makes. The collective decisions of a society shape a society. The degree of freedom one feels varies from person to person, but however free they feel actually indirectly shapes their society. Understanding this concept can grant invaluable insight on the dynamics of a society and their patterns of behavior. James M. Buchanan (1975) suggested that social stability requires an agreement on and enforcement of a structure of individual rights, meaning that in a society there is a general consensus that they all have the freedom to act in tolerable ways and make certain decisions. This also promotes the idea that there are still boundaries to the freedom we perceive and fight to keep. It’s fairly obvious at this point that freedom is not exactly what most would think it is and that the term is often confused with free will. John Locke (1997) believed that free will was the ability to override instinct. For instance, if one is hungry and they chooses not to eat to do something else, they have exercised their free will. But with true freedom, one would be able to choose not to eat at all. We know that we have freedom of speech and press and all of the other amendment, but they were given to us. True freedom has no proposal and enactment date. You either have it or you don’t. The fact is that the conundrum called freedom is actually not freedom at all. In James M. Buchanan’s (1975) study of commonality and non-economic interaction, he stated that freedom as a norm or rule for social intercourse has little or no meaning until or unless individuals are first identified in terms of acknowledged limits of behavior. With that said, if we all carried on with no interaction and did what ever we wanted to, that would be as close as we could ever get to freedom. Within a society, culture or family setting, there will always be a behavioral boundary. While we have the free will to make decisions within those boundaries, we do not have the freedom to make our own boundaries as long as we are a part of a society. Finding freedom Further research into the concept of human freedom, I believe, would offer a great deal of value to the field of sociology. One’s own sense of freedom plays a huge part in their day to day actions and what path they choose in their own life. Sociology, by definition, is the study of the development, structure and functioning of human society. The development of society is based on decisions made by those who lead the way of development and the citizens who decided elect them based on their own sense and concept of freedom. It is my understanding that the very foundation of a society is the peoples’ sense of freedom, collectively, and they make choices based on that sense of freedom. This could give insight into the research of crime, poverty and suicide rates as well as chronic depression and people who are withdrawn from society. Finding Freedom Discussion Though it may not be easy to grasp immediately, that our sense of freedom is what drives us, at this point it would be hard to object. Dr. Mark Cooray (1997) explained freedom is the liberty of the individual coupled with concern by the liberated individual for the liberties of others. In other words what we call freedom is merely a box that we are allowed to move about freely within. Only because our actions affect others and their sense of freedom do we have to operate within the confines of freedom. That leads me to believe that true freedom can only be achieved by on outside of a society or one happens to be an exception to the rule. It has been found that no one can truly be free without encroaching the freedom of another within their society. According the John Locke (1997) freedom is merely a better word for free will, when thought of literally, as there is no tangible concept of actually freedom. With that said, I can still conclude that people still do not feel as free as they actually are although still confined to the boundaries of freedom. This inference, I believe, could help with the research of several of societies ailments and perhaps empower some of those who may feel helpless and resort to deviant means.

Definition and Examples of Conditional Sentences

Definition and Examples of Conditional Sentences In English grammar, a conditional sentence is a type of sentence that expresses one situation (the condition,  antecedent, or protasis in a dependent clause) as a condition for the occurrence of another situation (the result, consequent, or apodosis in the main clause). Put simply, the basic structure underlying most conditional sentences can be expressed as, If this, then that. Also called a conditional construction  or a conditional. In the field of logic, a conditional sentence is sometimes referred to as an implication. A conditional sentence contains a conditional clause, which is a type of adverbial clause  usually (but not always) introduced by the subordinating conjunction if, as in, If I pass this course, I will graduate on time. The main clause in a conditional sentence often includes the modal  will, would, can, or could. A subjunctive conditional is a conditional sentence in the subjunctive mood, such as, If he were to show up here right now, Id tell him the truth. Examples and Observations In each of the following examples, the italicized word group is a conditional clause. The sentence as a whole is a conditional sentence. If I ruled the world,Every man would be as free as a bird,Every voice would be a voice to be heard,Take my word, we would treasure each day that occurred.(Leslie Bricusse  and  Cyril Ornadel, If I Ruled the World. Pickwick, 1963)If I ruled the world, was king on the throne,Id make peace in every culture, build the homeless a home.(Nasir Jones et al., If I Ruled the World (Imagine That), 1995)Now, if I had  been that young woman, I would have planted my feet, looked those men straight in the eye, and dared them to try to put me on board a ship when I didnt want to go, but times were different then.(Jennifer Chiaverini,  The Quilters Apprentice, 1999)Even  if she were to  confide in them all her suspicions, even  if she were to  tell them about the pills, even  if she were to  lead them to her locker at the Greyhound Bus Terminal and actually present them with her bloodied dress and the stacks of hundred-dollar bills, she would be regarded with skepticism and outrig ht disbelief.(Joy Fielding, See Jane Run. William Morrow, 1991) All this can be a dreadfully boring business, unless you think you have a future.(Bernard Malamud, The German Refugee, 1964)Conditional Clauses That Are Not Introduced by a Conjunction- It is possible to construct conditional clauses that do not begin with if or unless. The commonest way of doing this is to begin the clause with one of these words: were, should, had. For example: Were I to own a new BMW car, another ten microcomputers would be at my command, so their advertisements claim.Should you succeed in becoming a planner, you would be helping to create these parameters.Had I ignored my fitness, I could never have played international cricket for twenty years. (John Seely, Oxford A-Z of Grammar and Punctuation, rev. 2nd ed. Oxford University Press, 2013)-  Were I to take a turn into the country,  the trees would present a leafless, wintry appearance.(Thomas Paine, winter 1792)- Let Domingo be my heir  should I fail to return, I said to the House that surrounded me.(Jane L indskold, Child of a Rainless Year. Tor Books, 2005)- Yet this strangest of all things that ever came to earth from outer space must have fallen while I was sitting there, visible to me  had I only  looked up as it passed.(H.G. Wells,  The War of the Worlds, 1897) Using the Past Perfect in ConditionalsIf the situations are set in the past, the past perfect is used in the conditional clause and a past perfect modal, usually would have, in the main clause. - If we had been there yesterday, we would have seen them. (But we were not there yesterday.)- If he had been given a good mark, he would have told me. (But it seems that he was not given a good mark.) If the auxiliary in the conditional clause is were, had, or should, we can omit if and front the auxiliary: - Were she here now, there would be no problem.- Had we stayed at home, we would have met them.- Should you see him, give him my best wishes. (Sidney Greenbaum and Gerald Nelson, An Introduction to English Grammar, 2nd ed. Pearson, 2002)Direct and Indirect ConditionsConditional clauses generally express a direct condition, indicating that the truth of the host clause (or apodosis) is dependent on the fulfillment of the condition in the conditional clause (or protasis). However, some condit ional clauses may express an indirect condition that is related to the speech act: [18]   And if I remember rightly you had jaundice didnt you (if I remember rightly it would be true to say)[19]   I mean if I told you honestly things can be really interesting [...][20]   [. . .] I did need to have a need to say , that I was doing something because uhm , otherwise I wouldnt be anybody if you see what I mean Direct conditions may be either open (or real) or hypothetical (or closed or unreal). Open conditions leave completely open whether the condition will be fulfilled: [21] Youre going to have huge trouble , if youve infected me. In [21] the speaker does not give any indication whether he or she believes that the conditionthe infection by the person addressedhas been fulfilled.(Sidney Greenbaum, Oxford English Grammar. Oxford University Press, 1996) Material Conditionals in LogicA material conditional expresses  another type of connection, neither causal nor logical yet similar to other types of conditionals in that it cannot be true if it has a false consequent and a true antecedent. An example of a material conditional is If humans live on Jupiter, then my great-grandmother was an astronaut. Although no natural link connects the antecedent and  consequent in this conditional, its meaning is clear. The point of this sentence, and others like it in English, is to emphasize that the antecedent is false. It is a way of expressing No way is there human life on Jupiter.Although material conditionals are often just  humorous ways of stating that something is false, we can draw from them a logically useful principle about interpreting sentential connectives. In a material conditional, the if... then... that connects the component sentences is a  truth-functional connective. This means that the truth of the conditional sentence is determined completely by (is a  function of) the truth of its component sentences. The only circumstance under which a material is false is when it has a true antecedent and a false consequent. That is why the compound sentence If theres human life on Jupiter then my great-grandmother was an astronaut can be used to state the falsity of there is human life on Jupiter. The consequent of the conditional (my great-grandmother was an astronaut) is obviously false. Yet the sentence as a whole is understood as true. But if the antecedent were true, then the conditional would be false, for it would have a true antecedent and a false consequent. Thus, a material conditional  of the form If (antecedent), then (consequent) is true unless the antecedent is true and the consequent is false. (Merrilee H. Salmon,  Introduction to Logic and Critical Thinking, 6th ed. Wadsworth, Cengage, 2013)

How and When to Control Paper Wasps

How and When to Control Paper Wasps Though paper wasps are beneficial insects, they tend to nest in close proximity to people, putting us at risk for stings. In some cases, it may be necessary to control paper wasps to minimize such risk. What Are Paper Wasps? Paper wasps construct the familiar, open-celled paper nests we often see suspended from eaves or porch ceilings. Most paper wasps  in North America belong to the genus Polistes. Although their tendency to sting in defense of their nests can be of concern, these wasps do serve an important ecological purpose as predators of other insects. They collect caterpillars, beetle larvae, and other insect prey to feed their young. Dont be too quick to get rid of a paper wasp colony if it isnt causing a problem.   Each year, the paper wasp queen must build a new nest, which she does by masticating wood fibers into a pliable pulp. After she raises her first generation of eggs, these offspring will assume the role of construction workers, expanding the nest to meet the needs of the growing colony. By summer, the paper wasp nest can be quite large, reaching a width of 6–8 inches. In fall, freezing temperatures will kill all but the queen, who seeks shelter and hibernates for the winter. The nest degrades over winter and is rarely reused the next year. As with any insect, its important to identify it before determining how and when control is necessary. Be sure you know the differences between wasps, yellowjackets, and hornets before taking action. Do Paper Wasps Sting? Paper wasps can and will sting in defense of their nest or when threatened. Unlike honeybees, which have barbed stings and can sting only once, paper wasps can sting multiple times. A paper wasp can call other colony members using alarm pheromones, chemical messages that tell other wasps to help defend the nest from a threat. Try to stay calm and avoid swatting at paper wasps. Consider Coexisting Peacefully Before you do anything to get rid of paper wasps around your home, ask yourself if you can tolerate their presence. Paper wasps help keep hungry caterpillars and other plant pests in check, benefiting your landscape and garden. If a paper wasp nest is located on your property but away from high-use areas, consider leaving it alone. Although they do sting, they do so only in response to a threat. Humans and paper wasps can often coexist peacefully. Obviously, when someone in your household has a wasp venom allergy, you may need to remove any nests to minimize the risk of an allergic reaction to a sting. Use Caution Around Wasp Nests If a nest is located near an entrance to your home or by a porch or deck where you spend a lot of time, you may need to take action to control paper wasps. Check eaves, shutters, and other high-traffic areas in your yard early in the spring, when paper wasp queens are first building their nests. If you find one early in the spring, before the first generation of workers has reached adulthood, you can simply knock the nest down with a broom to discourage the queen from nesting in that location. Larger nests, or those found later in the season, should be handled cautiously. Never attempt to remove an active wasp nest during the day, when the insects are actively flying in and out of the nest. Wait until evening, when the paper wasps have settled in for the night, to treat or remove any nest. During periods of cool weather, you may be able to treat wasp nests, as the insects become lethargic when temperatures dip down to 50 F or lower. Advice on Using Sprays Chemical pesticides should be used as a control method of last resort for any insect pest. In this case, the safest method of eradicating paper wasps in a problem area is, indeed, with a commercial wasp spray. Look for a product labeled for use on wasps and hornets, and remember, the label is the law. You must read the label and follow all directions for using any pesticide product. Wasp sprays usually come with a propellant that allows you to spray the pesticide from a safe distance. Coat the nest in the pesticide, covering all the cells of the nest. Never stand directly below a paper wasp nest while applying the pesticide. Wasps may drop from the nest, and you also risk getting the chemical in your eyes or on your skin. Check the nest the next day for any signs of wasp activity. Before you remove a nest, you must be sure that no workers survived the pesticide application. Wasp sprays kill on contact. Wasps that were absent from the nest at the time you sprayed may return to the nest site. If you dont observe live wasps near the nest, use a broom or other long-handled tool to knock it down. Dispose of the nest by putting it in a sealed baggie and placing it in your household trash. Sources Cranshaw, Whitney. Garden Insects of North America.North Carolina Cooperative Extension.

The Impact of Outdoor Air Pollution Research Proposal

The Impact of Outdoor Air Pollution - Research Proposal Example When inhaled, they lead to throat irritation, digestive problems, chest complications as well as dizziness and fever. Chronic respiratory problems such as asthma also arise from the same (Brebbia & James 276). The research intends to analyze outdoor air pollution impact, which is a menace presently showing an upward trend. The health of human beings is at risk; hence seeking adequate and effective solutions is quite commendable. The audience that this research seeks to reach includes those who conduct human activities such as burning wood that contribute to air pollution. In addition, it tries to reach those affected by the same to offer help find solution to their problem. The government too is a target audience since they have to put strict measures to prevent avoidable pollution from occurring. The project will first begin by defining various forms of pollutions before focusing on outdoor air pollution (Frumkin 388). Then it will explore varied causes of outdoor air pollution (Ahmed & Triana 84). Some causes of outdoor air pollution are beyond control. In the case of pollen for example, pollination is natural process that cannot be controlled. Wind is also a natural process and is responsible for transporting the pollutants from one atmospheric environment to another. Survey also will encompass seeking information regarding neighboring factories to evaluate how they dispose their wastes and their effects to the immediate populace. This is especially varied particles deposited in the atmosphere. This project will go a long way into protecting the lives and health of people who are at risk of inhaling the contaminants. I request permission to proceed with this proposal to prove that outdoor air pollution is a call for concern and that there are possible remedies to the same.

Annotated Bibliography of Air Pollution in Beijing

Of Air Pollution in Beijing - Annotated Bibliography Example With this kind of primary data, it was possible to solidly cement the research evidence and thus eloquently state out the findings of the research. With this data, it was possible to tell what the position of the city is from a first-hand point of view. This interview was aimed at establishing hard facts from residents about the observable effects of pollution within the city. The interviewee as born and brought up in the outskirts of Beijing. He has lived his entire life literally in the city having schooled and currently working there.

Final exam paper two part - Essay Example According to Cicero 3 all human beings are the same. We all have the urge to be together. We cannot live in isolation and that we come together in communities from a desire to be together both for fulfillment of our nature as social beings and for company. As Aristotle has said, â€Å"man is social being†. He argues that nature has endowed humans with reason so that we can understand the natural urge and guide our actions in order for us to live together. For Cicero, not only are all humans one species, but also all communities with â€Å"an innate desires on the part of human beings to form communities.† He agrees with Aristotle that humans are political or social animals. But that nature has given to mankind â€Å"†¦ a compulsion to do good and †¦ a desire to defend the well being of the community†¦Ã¢â‚¬  (Marcus 4). What this means is that as human beings we have constructive toward each other and are urged by nature to seek the well being not just o f themselves but of the whole community. The opposite of this is selfishness and for Cicero this is acting against human nature. Cicero even marvels at the power of human reason. â€Å"Reason in fact †¦ the one thing in which we are superior to the beast which enables us to make valid deductions, to argue, refute, debate, solve problems, draw conclusion †¦ that certainly is common to all of us (John 4). It is this common reason that allows each individual to examine nature and come to understand what nature urges him or her to do. This is his basis for universal understanding of the institution, it is better to live with other people. He takes a stand that Law is the highest reason, implanted in nature, which prescribes those things which ought to be done and forbids the contrary (John 10). For Cicero, â€Å"The highest reason inherent in nature which enjoins what out to be done and forbids that opposite† Living by this natural law

Improving Decision Making in the Coca-Cola Company Case Study

Improving Decision Making in the Coca-Cola Company - Case Study Example The experience of Coca-Cola which is discussed above has become a classic marketing tale documenting the mistakes that managers can make in their decision-making process. The failure of Coca-Cola can be largely attributed to two factors namely, narrow definition of its marketing research problem and poor judgment in interpreting the research planning strategies around it (Kotler and Armstrong 2001). The experience of Coca-Cola which is discussed above has become a classic marketing tale documenting the mistakes that managers can make in their decision-making process. The failure of Coca-Cola can be largely attributed to two factors namely, narrow definition of its marketing research problem and poor judgment in interpreting the research planning strategies around it (Kotler and Armstrong 2001). Managers became narrow-minded and myopic in diagnosing the problem that Coca-Cola was facing. Instead of looking at all the factors which may be influencing the buyers in their purchases, thes e managers only look at the taste of the product. Their research has focused only at the taste ignoring the customers’ feelings about dropping the product. It turned out that Coke’s symbolic meaning in the United States is more important than taste. Coca-Cola’s managers also failed to use wise judgment in the introduction of New Coke. Even though their decision of dropping the old Coke is warranted by the 60% acceptance rate of the new formula, they did not anticipate that the 40% might still like the old Coke better.  Conclusion Decision-making process must not be too narrow to overlook some of the important factors and details. As the situation of Coca-Cola shows us, managers should always avoid hasty generalizations and marketing myopia. In the business environment, decisions should always be grounded on all the factors affecting performance. Focusing on one aspect only will yield a one-sided and inadequate decision.

Reserch method Essay Example | Topics and Well Written Essays - 2500 words

Reserch method - Essay Example The domain of internet mass media systems has only recently been recognised but it is without a doubt a prolific form of mass media in its own right. While mass media has affected other aspects of modern life, there is little deniability that mass media has had an overwhelming effect on contemporary politics. This is all the more true for nations that pursue the path of democracy since the average citizen is an important part of the democratic structure. The opinion of the ordinary person in a democratic system makes all the difference between success and failure in regards to political issues. It has been argued that the mass media tends to bear an overbearing influence on the modern man in a democratic system so that the democratic process is biased. On the other hand, it has been advocated that mass media outlets only have the power to present people with the issues to think about while people decide on the issues themselves. The American Presidential race for example has come und er scrutiny time and again for it being tilted to favour one faction or the other due to overarching mass media influences. These mass media influences are chosen by a handful of mass media organisers who tend to exert sizable influence on the overall political process. This is only possible due to the very nature of the mass media structure that provides limited input exposure to the common man. Mass media gurus and bosses get to choose what is shown and what is not. Arguably, this should tend to subside with the introduction of more free mass media outlets such as the internet. Previous mass media streams whether print, broadcast or digital have been controlled exclusively by the mass media bureaucracy due to the inherent design of the overall process. However, the internet is highly differentiated from all of these mass media streams given that it is as accessible to the common person as it is to mass media gurus. The average person can simply go ahead and publish his views as he sees fit which was not possible under the conventional mass media regime given the limitations on what material to publish. This would also tend to indicate that the mass media in the form of the internet is free from the influence of overarching political structures. Hence, it could be assumed that the internet would serve as a means of liberation for the mass media that has been in the clutches of organisational structures for decades. The recent uprising in the Middle East sponsored by internet mass media especially social networking media has exposed a new dimension to mass media and politics. Mass media has been shown to be linked to political change without any remaining doubts since the Arab domino effect was able to remove three deeply entrenched dictatorial regimes. These regimes namely Ben Ali in Tunisia, Hosseni Mubarak in Egypt and Muammar Kaddafi in Libya had overwhelming control of mass media outlets except for the internet. Throughout the entire conflict, none of the se dictators were able to subject the internet mass media machine to their wishes. Consequently, internet mass media was used to disseminate information and to rally support against these political machinations. It could be inferred from these changes that the internet mass media has independence and potential for open and fair change. However, neither before nor after the Arab uprisings was internet mass med

In these Gothic novels, the authors use the characters, the setting, and different events to bring out the Gothic style. The setting may serve to create an atmosphere of gloom, mystery, and horror.

Authoritarian Rule in Latin America Essay Example for Free

Authoritarian Rule in Latin America Essay â€Å"Latin American politics since independence have been characterized by instability, authoritarianism, and violence. In a three page essay please discuss the role of the military in creating such problems using the chapter in the course reader entitled â€Å"The Good Sailor. † Also, discuss whether or not the Argentinean case is typical or unique to Latin America. Provide explanations and analysis from â€Å"The Good Sailor,† lecture, and the textbook. An â€Å"A† paper will use all three. Use size 12 Times New Roman font. The paper must be typed (or word-processed) on standard size paper (8 ? y 11) and double spaced with appropriate margins. Use MLA format with parenthetical citations-i. e. (Rosenberg, 84). † Violence in Latin America is a significant part because so much of it is political: planned, deliberate, and carried out by organized groups of society. It is used to make a point. The above quote supports that the violence and military is interrelated and it is used as tool by the military to instill fear and dominate people of the Latin America. Ranked as the third most unstable region in the world in the post-war era, political instability has been a pervasive problem in Latin America. Whether it is a caudillo, a charismatic boss with an armed following, or a general leading a golpe de estado or an authoritarian institution, Latin America is conceived as an authoritarian region always ruled by either military or civilian leaders. Only three Latin American countries were consistently democratic over the thirty year period from 1935 to 1964: Costa Rica, Colombia, and Venezuela. During this time, there were 56 changes of government by military coups in 20 Latin American nations. In sum, political instability is a persistent and pernicious problem in the region. The question arises how military insurrection remained instrument of ruling in Latin America. It might be because since the time of caudillos, violence when used as a method to rule has brought desired results and authority. So it has become a used and proven instrument in the ruler’s toolbox. Also, it might be possible that the institutional inertia of the violent politics as inherited from predecessor’s success is deep rooted in the psychic of the rulers. Brazil was the first of these Institutional dictatorships. When military rule began in 1964 after the overthrow of Joan Goulart, it was not a long project but hard liners in military demanded more and more until soft liners came into action in 1974 to loosen up the political rein. This military regime was institutionalized and created two political parties to channel political activity [Skidmore, Thomas Pg 358-360]. While in Chile, you will see the example to an institutional regime changing into personalistic one with emerging of a dictator Augustus Pinochet, who ruled Chile from 1973 to 1989. Pinochet staged a very bloody coup in which probably 2,000 people were killed in the coup and in the years immediately afterwards. Most Chileans supported some sort of army intervention, in part ironically because of their democratic history. They felt, It cant happen here. Our military isnt like the other militaries. They meant that the Chilean military cannot be as brutal as Argentinean military was. Our military will come in and restore order and clean house for six months and then leave. Seventeen years later, the military left after carrying on one of the most brutal and repressive regimes in Latin America and becoming a symbol of state terrorism. Argentina presents one of the most acute cases in the period after 1955. In this country during this period there occurred 12 military coups. While Colombias violence had its roots because of the lack of social order and the Government’s inability to place rules on a most chaotic society, in Argentina, the junta that came in power in military created exactly the opposite situation. When the military coup came into power in 1976; it suffocated Argentina with social order. It took over the educational institutions, changed the life style of people even their appearance. [Article â€Å"The Good Sailor† Pg. 13] Alfredo Astiz, a lieutenant general for the Navy who was active in it from 1970 to 1995. [Article â€Å"The Good Sailor† Pg. 24] Astiz was in Task Force 3. 2. 2 which killed more people during the Dirty War than any other group. The Dirty War lasted from 1976 until 1983 and involved people getting disappeared. The term disappeared describes those who vanished during this period and were probably killed by the military before being tortured in inhumanely ways. It is these trocities and the new and brutally creative ways to torture people that made the Argentinean military different from the other regimes in Latin America. The term Dirty War originates in the military junta itself, which claimed that a war, albeit with different methods was necessary to maintain social order and eradicate political subversives. Although the junta claimed its objective to be the eradication of guerrilla activity, the repression struck mostly the general population, and specifically all political opposition, trade unionists (half of the victims), students, and other civilians. Many others were forced to go into exile, and many remain in exile today. When the Dirty War was a year and a half old, it had disappeared more than 6,500 Argentines. [Article â€Å"The Good Sailor† Pg. 12. ] Even though the military knew in 1978 that 90% of the left was eradicated, they kept on fighting against imaginary subversives for 5 more years. Human rights were not important to the Argentines. Despite contrary opinion from the military, the article â€Å"The Good Sailor† by Tina Rosenberg proves that excessive torture occurred. It is evident from testimonies in the article and the experience of Vilerinos. Article â€Å"The Good Sailor† Pg. 15, 16. ] He talked about a torture chamber with an electric shock machine, torturing instruments and sand bags to hit people so no marks would show up. The military General and even the low rank officers believed that they have godlike powers instilled in them and it is their duty to clear all the dirt from the society by killing people they see fit. They had no shame in executing horrendous tortures instead they took pride and enjoyed the process. As compared to Argentina, Mexico had one part rule (PRI ruled since 1929 to 2000) rather than military wars but still there was colossal bloodshed. It is not that only military intervention brings in political instability and violence as Mexico is a live example of both. However, after the study of the article â€Å"The Good Sailor† and reading the book â€Å"Modern Latin America† it seems to me that the extent of atrocities military regimes brought is incomparable to civil dictatorship. It is their hunger for power and vehemence to rule that make them feel they are god and have right to â€Å"punish† people. â€Å"Here we are the only gods† said by a torturer in a chamber after brutally torturing a 52 year old women.

Ecotourism In Dominican Republic Tourism Essay

Ecotourism In Dominican Republic Tourism Essay Ecotourism has grown rapidly since the late 1980s, which is the fastest development of all the events in the tourism industry. The word ecotourism is from ecological tourism. According to the definition of ecotourism is Responsible travel to natural areas that conserves the environment and improves the well-being of local people.'( Martha Honey,1990).Furthermore, ecotourism also includes that traveling to natural destinationsà £Ã¢â€š ¬Ã‚ building environmental awarenessà £Ã¢â€š ¬Ã‚ respecting local culturesà £Ã¢â€š ¬Ã‚ supporting human rights and democratic movements Nowadays, more and more countries and national organizationsà £Ã¢â€š ¬Ã‚ including many individuals show high respect for worldwide ecotourism. Some countries like Kenyaà £Ã¢â€š ¬Ã‚ Nepalà £Ã¢â€š ¬Ã‚ Australiaà £Ã¢â€š ¬Ã‚ Antarctica and Dominica. There are also many famous organizations such as World Tourism Organization (WTO)à £Ã¢â€š ¬Ã‚ United Nations Environmental Programmers (UNEP)à £Ã¢â€š ¬Ã‚ The International Ecotourism Society (TIES). It is considered that that is the reason why ecotourism can develop so fast that it can affect the world and our planet Earth greatly. (Transitions abroad, n.d.) The Dominican Republic, as the name Natural Isle of the Caribbean goes, the country which is an island nation in the Caribbean Sea. As well as having many mountainous rainforestsà £Ã¢â€š ¬Ã‚ it is home to many rare plantsà £Ã¢â€š ¬Ã‚ birds and animals in its limited 754  square kilometers. This is the reason that led to the Dominican Republic becoming an ecotourism island. Many people still believe that the lack of terrain and development funding is the other key why many people and global organizations claim that the Dominican Republic is well-known for its ecotourism industry. Although the Dominican Republic has many different cultures and customs like French cultureà £Ã¢â€š ¬Ã‚ Spanish custom and local culture, for example, traditional Aztec culture and traditional Indian culture ,these different cultural phenomenon did not affect the natural system .Otherwise, natural ecotourism plays an important part in the Dominican Republics economy. All in all, people can learn more about Ecotourism in Dominican Republic. This research paper will examine four main aspects of ecotourism in the Dominican Republic: International and national organizations supportà £Ã¢â€š ¬Ã‚ Advantages Disadvantagesà £Ã¢â€š ¬Ã‚ the success of Ecotourism programmes and Future developments. With the remarkable improvement of peoples living standards ¼Ã…’ecotourism has aroused wide public concern. USAID ¼Ã…’an American organization, has put a lot of efforts into developing ecotourism. USAID programs brought the public and personal sectors together, in order to support sustainable ecotourism development. USAID also gave a helping hand to creating a vision and seeking a key to ecotourism in the Dominican republics future. Laying emphasis on increasing leadership roles of local small- and medium-sized enterprises (SMEs), increasing the communication of society à £Ã¢â€š ¬Ã‚ developing marketing toolsà £Ã¢â€š ¬Ã‚ reopening the local airport ,and strengthening the quality of the services of ecotourism while using natural resources.(USAID ¼Ã…’2009) The Tourism Sector Development Program, funded by the European Special Framework of Assistance ¼Ã‹â€ SFA,2006 ¼Ã¢â‚¬ °is an ecotourism program which is two years old, being implemented by the Ministry of Tourism and Legal Affairs (MT LA). Improving on the competitiveness of the tourism sector  in the Dominican Republic is an important part of this program. Another aim of this program is to seek to build the main connection of the society and ecotourism between tourism and the agricultural and rural parts. Furthermore, it aims to improve the Dominican Republics position in the market place through increased marketing and promotions. The Tourism Sector Development Programme focuses on society tourism products development in the Dominican Republic. Help is given to these communities in the areas of foundation development; human resources development and business planning; package and tour development and marketing. The main developing marketing is in the key markets of Europe and Caribbean and a range of additional materials to aid in the marketing of the ecotourism in the Dominican Republic. (ODT, n.d.) In many peoples opinion, ecotourism is the symbol of ecosystem and ecology. It cannot be denied that ecotourism benefits not only our society, but also the nature system. Firstly, people who have ecotourism in some natural places can educate others by teaching them about plants and animals, which promotes conservation of natural assets. Secondly, ecotourism can give people a deeper understanding of the local nature, and many professors predict that ecotourism can bring people closer to nature. Ecotourism can enhance the cultural integrity of the local people. Thirdly, it is considered that ecotourism can open peoples minds and broaden their horizons. Furthermore, countries and governments also get finical achievements. Many people think that visitors may become more aware of the surrounding environmental wealth. With the emphasis laid by governments, ecotourism will attract many people from home and abroad, so local people and visitors have to spend money during the activities in ecotourism. Money can go back into the country through this cycle, the more energy governments put on it, the better this system will go back to the country. Moreover, this cycle system can provide employment. In addition, this cycle system provides financial incentives to encourage local people to protect their environment.(Heritage, n.d.) One of the extra ecotourism industries is called ecotourism business. Human beings have little or no adverse impact on environment. Just what is mentioned in the financial ecotourism cycle system, ecotourism business provides local employment. It is thought that little waste is generated. In the end, ecotourism business provides human beings with educational and enlightening experiences. Ecotourism is a responsible tourism to the natural environments. Although ecotourism is one of the fastest growing additions to the tourism industry, some people predict that ecotourism has a large number of disadvantages, such as costs to the peopleà £Ã¢â€š ¬Ã‚ community and the ecological balance. Many local people firmly believe that how to protect the ecotourism system is the largest problems in the environmental development. It is undeniable that there are also many other elements affecting this system. Another major element is the increasing human activity. People like jogging and relaxing in the natural environment, which means agricultural clearance. That is the reason why so many professors think the ecotourism are the production waste and effluent pollution. Ecotourism tends to Imaging if a place became an ecotourism tourist attractions, many businessmen want to attract many people, so the environment may be damaged. Increasing use of environmental resources by the humans leads to pollution, even in the smallest places, causing environment problems. Different places have different cultures. There may be competition for ecotourism income between various groups leading to social disharmony. The bar graph has drawn great public attention in the Dominican Republic, which has compared the economic freedom and world average. Thanks to the Dominican Ecological Corridor Network, developed in 1995 ,as a key to connect the paradigm of the new trends for the recovery of the ecological balanceà £Ã¢â€š ¬Ã‚ the natural resources and the sustainable production of these materials. Although the figure of economic freedom vs. world average looks very large, the figure is decreasing day by day. In fact, many figures is closer to world average like property rightsà £Ã¢â€š ¬Ã‚ .corruptionà £Ã¢â€š ¬Ã‚ labor freedom and monetary freedom. To peoples amazement, there are also many figures surpassing world average. For example, investment freedoms has surpassed at roughly 5%;government size has surpassed about 28%;others like facial freedom has surpassed about 6% ,and trade freedom has surpassed 2%. No matter how closer the economic freedom to the world average, how larger the declining of the Dominican republics economic freedom to the world average, people always see the distance not only between economic freedom and world average, but also between ecotourism and peoples According to the WTO line graph for the period between 1989 and 1998, there was a stable growth of international tourism arrivals at 10% and international tourism receipts at 9%. (Weaver, 2001) This tabular data compares tourist arrival numbers in the different parts of the world from 1995 to 2020. Annual percentage increases a significant declining in all markets during 1995 to 2020 in the whole world. In fact, international arrivals are forecasted that the growth from 673 million in 2000 to 1.05 billion in 2010, and 1.6 billion in 2020. Factually, these projections are based on increasing figures rates every year of 4.2% to the end of the 1990s and the figures will at between 4% and 5% during first decade of the 21st century. Europe was the first since 1995. According to the research, the tourist arrivals in Europe will still higher than other places, such as Pacificà £Ã¢â€š ¬Ã‚ Americaà £Ã¢â€š ¬Ã‚ Africa and Middle East. People in the Dominican Republic are serious about making the country into a model of ecotourism in the Caribbean areas. It is necessary for human beings to further understand the expectations and behavior of visitors to natural areas and features. People can gain further experience from their trips without bringing about any negative effects on the tourist attractions that they visit, so people must be prepared to try their best to educate people in handling the issue of sustainable development and conservation as the relations to the specific sites. People have the potential to take on the challenge and realization of the chances that ecotourism is the way forward. ¼Ã‹â€ Xavier ¼Ã…’n.d. ¼Ã¢â‚¬ ° Ecotourism attracts ecological professors and socialists, focusing on individual growthà £Ã¢â€š ¬Ã‚ volunteering and environmental responsibility. Responsible ecotourism means minimizing the negative aspects of traditional tourism on the environment and improving cultural integrity of local people. Furthermore, environmental evaluationà £Ã¢â€š ¬Ã‚ cultural factors and promotion of recycling are also playing important roles in ecotourism. Ecotourism allows the government to have more chance to preserve the natural environment. It is obvious that ecotourism has a high sense of responsibility when it comes to promoting harmony between human beings and nature.
