Five Traits Essay

1.Define and discuss the importance of the following traits associated with leaders: intelligence, self-confidence, determination, integrity, and sociability. Is this list all inclusive? a.Intelligence: Having a strong verbal ability, perceptual ability, and reasoning abilities; Leaders intellectual abilities, however, should not differ too much from their subordinates; Intelligence is also defined as a trait that significantly contributes to a leader’s acquisition of complex problem-solving skills and social judgement skills; Intelligent leaders have the ability to consider every situation individually and make an assessment as to what is the best solution. b.Self-Confidence: The ability to be certain about one’s competencies and skills is self-confidence; Includes both self-esteem and self-assurance; Self-confidence is an essential trait for any leader because without self-confidence it may become harder for followers to fully trust their leader c.Determination: Determination is the desire to get a job done and includes characteristics such as initiative, persistence, dominance, and drive; these people are proactive and have the perseverance to face obstacles; this trait is needed in order for leaders and followers to overcome goals. d.Integrity: Integrity is the quality of honesty and trustworthiness; these people are those who adhere to a strong set of principles and take responsibility for their actions; Leaders need integrity in order to inspire confidence in others since they are trusted to do what they say they are going to do. e.Sociability: A leader’s inclination to seek out pleasant social relationships; people who possess sociability are able to create strong relationships with their fellow followers. f.The five traits described above are all traits in which strong leaders possess. While the list is certainly not all-inclusive, these five seem to be essential in order to produce a strong and successful leade r.

Natural Disaster

Earthquake, shaking of the Earth’s surface caused by rapid movement of the Earth’s rocky outer layer. Earthquakes occur when energy stored within the Earth, usually in the form of strain in rocks, suddenly releases. This energy is transmitted to the surface of the Earth by earthquake waves. The destruction an earthquake causes depends on its magnitude and duration, or the amount of shaking that occurs. A structure’s design and the materials used in its construction also affect the amount of damage the structure incurs. Earthquakes vary from small, imperceptible shaking to large shocks felt over thousands of kilometers.Earthquakes can deform the ground, make buildings and other structures collapse, and create tsunamis (large sea waves). Lives may be lost in the resulting destruction. In the last 500 years, several million people have been killed by earthquakes around the world, including over 240,000 in the 1976 T’ang-Shan, China, earthquake. Worldwide, ear thquakes have also caused severe property and structural damage. Adequate precautions, such as education, emergency planning, and constructing stronger, more flexible, safely designed structures, can limit the loss of life and decrease the damage caused by earthquakes.Focus and Epicenter- The point within the Earth along the rupturing geological fault where an earthquake originates is called the focus, or hypocenter. The point on the Earth’s surface directly above the focus is called the epicenter. Faults- Stress in the Earth’s crust creates faults, resulting in earthquakes. The properties of an earthquake depend strongly on the type of fault slip, or movement along the fault, that causes the earthquake. Geologists categorize faults according to the direction of the fault slip.The surface between the two sides of a fault lies in a plane, and the direction of the plane is usually not vertical; rather it dips at an angle into the Earth. Waves- The sudden movement of rock s along a fault causes vibrations that transmit energy through the Earth in the form of waves. Waves that travel in the rocks below the surface of the Earth are called body waves, and there are two types of body waves: primary, or P, waves, and secondary, or S, waves. The S waves, also known as shearing waves, move the ground back and forth Effects Of EarthquakeGround Shaking and Landslides-Earthquake waves make the ground move, shaking buildings and causing poorly designed or weak structures to partially or totally collapse. The ground shaking weakens soils and foundation materials under structures and causes dramatic changes in fine-grained soils. During an earthquake, water-saturated sandy soil becomes like liquid mud, an effect called liquefaction. Liquefaction causes damage as the foundation soil beneath structures and buildings weakens. Fire-Another post-earthquake threat is fire, such as the fires.The amount of damage caused by post-earthquake fire depends on the types of bui lding materials used, whether water lines are intact, and whether natural gas mains have been broken. Ruptured gas mains may lead to numerous fires, and fire fighting cannot be effective if the water mains are not intact to transport water to the fires. Tsunami Waves and Flooding- Along the coasts, sea waves called tsunamis that accompany some large earthquakes centered under the ocean can cause more death and damage than ground shaking.Tsunamis are usually made up of several oceanic waves that travel out from the slipped fault and arrive one after the other on shore. They can strike without warning, often in places very distant from the epicenter of the earthquake. Tsunami waves are sometimes inaccurately referred to as tidal waves, but tidal forces do not cause them. Rather, tsunamis occur when a major fault under the ocean floor suddenly slips. The displaced rock pushes water above it like a giant paddle, producing powerful water waves at the ocean surface.The ocean waves spread out from the vicinity of the earthquake source and move across the ocean until they reach the coastline, where their height increases as they reach the continental shelf, the part of the Earth’s crust that slopes, or rises, from the ocean floor up to the land. Disease-Catastrophic earthquakes can create a risk of widespread disease outbreaks, especially in underdeveloped countries. Damage to water supply lines, sewage lines, and hospital facilities as well as lack of housing may lead to conditions that contribute to the spread of contagious diseases, such as influenza (the flu) and other viral infections.Blizzard Blizzard, severe storm characterized by extreme cold, strong winds, and a heavy snowfall. These storms are most common to the western United States but sometimes occur in other parts of the country. According to the U. S. National Weather Service, winds of 35 mph (56. 3 km/h) or more and visibility of 0. 25 mi (0. 40 km) or less are conditions that, if they endure fo r three hours, define a blizzard. The great blizzard of March 11-14, 1888, which covered the eastern U. S. , was perhaps the most paralyzing of any storm on record.Cyclone Cyclone, in strict meteorological terminology, an area of low atmospheric pressure surrounded by a wind system blowing, in the northern hemisphere, in a counterclockwise direction. A corresponding high-pressure area with clockwise winds is known as an anticyclone. In the southern hemisphere these wind directions are reversed. Cyclones are commonly called lows and anticyclones highs. The term cyclone has often been more loosely applied to a storm and disturbance attending such pressure systems, particularly the violent tropical hurricane and the typhoon, which center on areas of unusually low pressure.Hurricane Hurricane, name given to violent storms that originate over the tropical or subtropical waters of the Atlantic Ocean, Caribbean Sea, Gulf of Mexico, or North Pacific Ocean east of the International Date Line . Such storms over the North Pacific west of the International Date Line are called typhoons; those elsewhere are known as tropical cyclones, which is the general name for all such storms including hurricanes and typhoons. These storms can cause great damage to property and loss of human life due to high winds, flooding, and large waves crashing against shorelines.How Hurricanes Form-Tropical cyclones form and grow over warm ocean water, drawing their energy from latent heat. Latent heat is the energy released when water vapor in rising hot, humid air condenses into clouds and rain. As warmed air rises, more air flows into the area where the air is rising, creating wind. The Earth’s rotation causes the wind to follow a curved path over the ocean (the Coriolis effect), which helps give tropical cyclones their circular appearance. Hurricanes and tropical cyclones form, maintain their strength, and grow only when they are over ocean water that is approximately 27 °C (80 °F). Such warmth causes large amounts of water to evaporate, making the air very humid. This warm water requirement accounts for the existence of tropical cyclone seasons, which occur generally during a hemisphere’s summer and autumn. Because water is slow to warm up and cool down, oceans do not become warm enough for tropical cyclones to occur in the spring. Oceans can become warm enough in the summer for hurricanes to develop, and the oceans also retain summer heat through the fall.Hurricanes weaken and die out when cut off from warm, humid air as they move over cooler water or land but can remain dangerous as they weaken. Hurricanes and other tropical cyclones begin as disorganized clusters of showers and thunderstorms. When one of these clusters becomes organized with its winds making a complete circle around a center, it is called a tropical depression. When a depression’s sustained winds reach 63 km/h (39 mph) or more, it becomes a tropical storm and is given a name. By definition, a tropical storm becomes a hurricane when winds reach 119 km/h (74 mph) or more.Characteristics of Hurricane-A hurricane consists of bands of thunderstorms that spiral toward the low-pressure center, or â€Å"eye† of the storm. Winds also spiral in toward the center, speeding up as they approach the eye. Large thunderstorms create an â€Å"eye wall† around the center where winds are the strongest. Winds in the eye itself are nearly calm, and the sky is often clear. Air pressures in the eye at the surface range from around 982 hectopascals (29 inches of mercury) in a weak hurricane to lower than 914 hectopascals (27 inches of mercury) in the strongest storms. Hectopascals are the metric unit of air pressure and are the same as millibars, a term used by many weather forecasters in the United States. Hectopascals is the preferred term in scientific journals and is being used more often in public forecasts in nations that use the metric system. )In a large, strong storm, hurricane-force winds may be felt over an area with a diameter of more than 100 km (60 m). The diameter of the area affected by gale winds and torrential rain can extend another 200 km (120 m) or more outward from the eye of the storm.The diameter of the eye may be less than 16 km (10 m) in a strong hurricane to more than 48 km (30 m) in a weak storm. The smaller the diameter of the eye, the stronger the hurricane winds will be. A hurricane’s strength is rated from Category 1, which has winds of at least 119 km/h (74 mph), to Category 5, which has winds of more than 249 km/h (155 mph). These categories, known as the Saffir-Simpson hurricane scale, were developed in the 1970s. Tornado Tornado, violently rotating column of air extending from ithin a thundercloud down to ground level. The strongest tornadoes may sweep houses from their foundations, destroy brick buildings, toss cars and school buses through the air, and even lift railroad cars from their tracks. To rnadoes vary in diameter from tens of meters to nearly 2 km (1 mi), with an average diameter of about 50 m (160 ft). Most tornadoes in the northern hemisphere create winds that blow counterclockwise around a center of extremely low atmospheric pressure. In the southern hemisphere the winds generally blow clockwise.Peak wind speeds can range from near 120 km/h (75 mph) to almost 500 km/h (300 mph). The forward motion of a tornado can range from a near standstill to almost 110 km/h (70 mph). A tornado becomes visible when a condensation funnel made of water vapor (a funnel cloud) forms in extreme low pressures, or when the tornado lofts dust, dirt, and debris upward from the ground. A mature tornado may be columnar or tilted, narrow or broad—sometimes so broad that it appears as if the parent thundercloud itself had descended to ground level. Some tornadoes resemble a swaying elephant's trunk.Others, especially very violent ones, may break into several intense suction vorticesà ¢â‚¬â€intense swirling masses of air—each of which rotates near the parent tornado. A suction vortex may be only a few meters in diameter, and thus can destroy one house while leaving a neighboring house relatively unscathed. Formation-Many tornadoes, including the strongest ones, develop from a special type of thunderstorm known as a supercell. A supercell is a long-lived, rotating thunderstorm 10 to 16 km (6 to 10 mi) in diameter that may last several hours, travel hundreds of miles, and produce several tornadoes.Supercell tornadoes are often produced in sequence, so that what appears to be a very long damage path from one tornado may actually be the result of a new tornado that forms in the area where the previous tornado died. Sometimes, tornado outbreaks occur, and swarms of supercell storms may occur. Each supercell may spawn a tornado or a sequence of tornadoes. The complete process of tornado formation in supercells is still debated among meteorologists. Scientists g enerally agree that the first stage in tornado formation is an interaction between the storm updraft and the winds.An updraft is a current of warm, moist air that rises upward through the thunderstorm. The updraft interacts with the winds, which must change with height in favorable ways for the interaction to occur. This interaction causes the updraft to rotate at the middle levels of the atmosphere. The rotating updraft, known as a mesocyclone, stabilizes the thunderstorm and gives it its long-lived supercell characteristics. The next stage is the development of a strong downdraft (a current of cooler air that moves in a downward direction) on the backside of the storm, known as a rear-flank downdraft.It is not clear whether the rear-flank downdraft is induced by rainfall or by pressure forces set up in the storm, although it becomes progressively colder as the rain evaporates into it. This cold air moves downward because it is denser than warm air. The speed of the downdraft incre ases and the air plunges to the ground, where it fans out at speeds that can exceed 160 km/h (100 mph). The favored location for the development of a tornado is at the area between this rear-flank downdraft and the main storm updraft.However, the details of why a tornado should form there are still not clear. The same condensation process that creates tornadoes makes visible the generally weaker sea-going tornadoes, called waterspouts. Waterspouts occur most frequently in tropical waters. OccurrenceThe United States has the highest average annual number of tornadoes in the world, about 800 per year. Outside the United States, Australia ranks second in tornado frequency. Tornadoes also occur in many other countries, including China, India, Russia, England, and Germany.Bangladesh has been struck several times by devastating killer tornadoes. In the United States, tornadoes occur in all 50 states. However, the region with the most tornadoes is â€Å"Tornado Alley,† a swath of th e Midwest extending from the Texas Gulf Coastal Plain northward through eastern South Dakota. Another area of high concentration is â€Å"Dixie Alley,† which extends across the Gulf Coastal Plain from south Texas eastward to Florida. Tornadoes are most frequent in the Midwest, where conditions are most favorable for the development of the severe thunderstorms that produce tornadoes.The Gulf of Mexico ensures a supply of moist, warm air that enables the storms to survive. Weather conditions that trigger severe thunderstorms are frequently in place here: convergence (flowing together) of air along boundaries between dry and moist air masses, convergence of air along the boundaries between warm and cold air masses, and low pressure systems in the upper atmosphere traveling eastward across the plains. In winter, tornado activity is usually confined to the Gulf Coastal Plain. In spring, the most active tornado season, tornadoes typically occur in central Tornado Alley and astward into the Ohio Valley. In summer, most tornadoes occur in a northern band stretching from the Dakotas eastward into Pennsylvania and southern New York State. The worst tornado disasters in the United States have claimed hundreds of lives. The Tri-State Outbreak of March 18, 1925, had the highest death toll: 740 people died in 7 tornadoes that struck Illinois, Missouri, and Indiana. The Super Outbreak of April 3-4, 1974, spawned 148 tornadoes (the most in any known outbreak) and killed 315 people from Alabama north to Ohio.Floods When it rains or snows, some of the water is retained by the soil, some is absorbed by vegetation, some evaporates, and the remainder, which reaches stream channels, is called runoff. Floods occur when soil and vegetation cannot absorb all the water; water then runs off the land in quantities that cannot be carried in stream channels or retained in natural ponds and constructed reservoirs. About 30 percent of all precipitation is runoff, and this amount may b e increased by melting snow masses.Periodic floods occur naturally on many rivers, forming an area known as the flood plain. These river floods often result from heavy rain, sometimes combined with melting snow, which causes the rivers to overflow their banks; a flood that rises and falls rapidly with little or no advance warning is called a flash flood. Flash floods usually result from intense rainfall over a relatively small area. Coastal areas are occasionally flooded by unusually high tides induced by severe winds over ocean surfaces, or by tsunamis caused by undersea earthquakes.Effects of Floods-Floods not only damage property and endanger the lives of humans and animals, but have other effects as well. Rapid runoff causes soil erosion as well as sediment deposition problems downstream. Spawning grounds for fish and other wildlife habitat are often destroyed. High-velocity currents increase flood damage; prolonged high floods delay traffic and interfere with drainage and econo mic use of lands. Bridge abutments, bank lines, sewer outfalls, and other structures within floodways are damaged, and navigation and hydroelectric power are often impaired.Financial losses due to floods are commonly millions of dollars each year. Drought Drought, condition of abnormally dry weather within a geographic region where some rain might usually be expected. A drought is thus quite different from a dry climate, which designates a region that is normally, or at least seasonally, dry. The term drought is applied to a period in which an unusual scarcity of rain causes a serious hydrological imbalance: Water-supply reservoirs empty, wells dry up, and crop damage ensues.The severity of the drought is gauged by the degree of moisture deficiency, its duration, and the size of the area affected. If the drought is brief, it is known as a dry spell, or partial drought. A partial drought is usually defined as more than 14 days without appreciable precipitation, whereas a drought may last for years. Droughts tend to be more severe in some areas than in others. Catastrophic droughts generally occur at latitudes of about 15 °-20 °, in areas bordering the permanently arid regions of the world.Permanent aridity is a characteristic of those areas where warm, tropical air masses, in descending to earth, become hotter and drier. When a poleward shift in the prevailing westerlies occurs , the high-pressure, anticyclonic conditions of the permanently arid regions impinge on areas that are normally subject to seasonally wet low-pressure weather and a drought ensues. A southward shift in the westerlies caused the most severe drought of the 20th century, the one that afflicted the African region called the Sahel for a dozen years, beginning in 1968.In North America, archaeological studies of Native Americans and statistics derived from long-term agricultural records show that six or seven centuries ago whole areas of the Southwest were abandoned by the indigenous agricu lturists because of repeated droughts and were never reoccupied. The statistics indicate that roughly every 22 years—with a precision of three to four years—a major drought occurs in the United States, most seriously affecting the Prairie and midwestern states.The disastrous drought of the 1930s, during which large areas of the Great Plains became known as the Dust Bowl, is one example. The effect of the drought was aggravated by overcropping, overpopulation, and lack of timely relief measures. In Africa, the Sahel drought was also aggravated by nonclimatic determinants such as overcropping, as well as by problems between nations and peoples unfriendly with one another. Although drought cannot be reliably predicted, certain precautions can be taken in drought-risk areas.These include construction of reservoirs to hold emergency water supplies, education to avoid overcropping and overgrazing, and programs to limit settlement in drought-prone areas. Volcano Volcano, moun tain or hill formed by the accumulation of materials erupted through one or more openings (called volcanic vents) in the earth's surface. The term volcano can also refer to the vents themselves. Most volcanoes have steep sides, but some can be gently sloping mountains or even flat tablelands, plateaus, or plains.The volcanoes above sea level are the best known, but the vast majority of the world's volcanoes lie beneath the sea, formed along the global oceanic ridge systems that crisscross the deep ocean floor . According to the Smithsonian Institution, 1,511 above-sea volcanoes have been active during the past 10,000 years, 539 of them erupting one or more times during written history. On average, 50 to 60 above-sea volcanoes worldwide are active in any given year; about half of these are continuations of eruptions from previous years, and the rest are new.Volcano Formation-All volcanoes are formed by the accumulation of magma (molten rock that forms below the earth's surface). Magm a can erupt through one or more volcanic vents, which can be a single opening, a cluster of openings, or a long crack, called a fissure vent. It forms deep within the earth, generally within the upper part of the mantle (one of the layers of the earth’s crust), or less commonly, within the base of the earth's crust. High temperatures and pressures are needed to form magma.The solid mantle or crustal rock must be melted under conditions typically reached at depths of 80 to 100 km (50 to 60 mi) below the earth’s surface. Once tiny droplets of magma are formed, they begin to rise because the magma is less dense than the solid rock surrounding it. The processes that cause the magma to rise are poorly understood, but it generally moves upward toward lower pressure regions, squeezing into spaces between minerals within the solid rock. As the individual magma droplets rise, they join to form ever-larger blobs and move toward the surface.The larger the rising blob of magma, th e easier it moves. Rising magma does not reach the surface in a steady manner but tends to accumulate in one or more underground storage regions, called magma reservoirs, before it erupts onto the surface. With each eruption, whether explosive or nonexplosive, the material erupted adds another layer to the growing volcano. After many eruptions, the volcanic materials pile up around the vent or vents. These piles form a topographic feature, such as a hill, mountain, plateau, or crater, that we recognize as a volcano.Most of the earth's volcanoes are formed beneath the oceans, and their locations have been documented in recent decades by mapping of the ocean floor. Volcanic Materials- 1-Lava-Lava is magma that breaks the surface and erupts from a volcano. If the magma is very fluid, it flows rapidly down the volcano’s slopes. Lava that is more sticky and less fluid moves slower. Lava flows that have a continuous, smooth, ropy, or billowy surface are called pahoehoe (pronounced pah HOH ee hoh ee) flows, while aa (pronounced ah ah) flows have a jagged surface composed of loose, irregularly shaped lava chunks.Once cooled, pahoehoe forms smooth rocks, while aa forms jagged rocks. The words pahoehoe and aa are Hawaiian terms that describe the texture of the lava. Lava may also be described in terms of its composition and the type of rock it forms. Basalt, andesite, , and rhyolite are all different kinds of rock that form from lava. Each type of rock, and the lava from which it forms, contains a different amount of the compound silicon dioxide. Basaltic lava has the least amount of silicon dioxide, andesitic and dacitic lava have medium levels of silicon dioxide, while rhyolitic lava has the most. -Tephra-Tephra, or pyroclastic material, is made of rock fragments formed by explosive shattering of sticky magma (see Pyroclastic Flow). The term pyroclastic is of Greek origin and means ‘fire-broken' (pyro, â€Å"fire†; klastos, â€Å"broken†). T ephra refers to any airborne pyroclastic material regardless of size or shape. The best-known tephra materials include pumice, cinders, and volcanic ash. These fragments are exploded when gases build up inside a volcano and produce an explosion. The pieces of magma are shot into the air during the explosion.Ash refers to fragments smaller than 2 mm (0. 08 in) in diameter. The finest ash is called volcanic dust and is made up of particles that are less than 0. 06 mm (0. 002 in) in diameter. Volcanic blocks, or bombs, are the largest fragments of tephra, more than 64 mm (2. 5 in) in diameter (baseball size or larger). Some bombs can be the size of a small car. 3-Gases-Gases, primarily in the form of steam, are released from volcanoes during eruptions. All eruptions, explosive or nonexplosive, are accompanied by the release of volcanic gas.The sudden escape of high-pressure volcanic gas from magma is the driving force for eruptions. Gases come from the magma itself or from the hot magm a coming into contact with water in the ground. Volcanic plumes can appear dark during an eruption because the gases are mixed with dark-colored materials such as tephra. Most volcanic gases predominantly consist of water vapor (steam), with carbon dioxide (CO2) and sulfur dioxide (SO2) being the next two most common compounds along with smaller amounts of chlorine and fluorine gases.Types of Volcano 1-Cinder Cones and Composite Volcanoes-Cinder cones and composite volcanoes have the familiar conelike shape that people most often associate with volcanoes. Some of these form beautifully symmetrical volcanic hills or mountains such as Paricutin Volcano in Mexico and Mount Fuji in Japan. Although both cinder cones and composite volcanoes are mostly the results of explosive eruptions, cinder cones consist exclusively of fragmental lava. This fragmental lava is erupted explosively and made up of cinders. -Shield Volcanoes-Shield volcanoes (also called volcanic shields) get their name fro m their distinctive, gently sloping mound-like shapes that resemble the fighting shields that ancient warriors carried into battle.Their shapes reflect the fact that they are constructed mainly of countless fluid basaltic lava flows that erupted nonexplosively. Such flows can easily spread great distances from the feeding volcanic vents, similar to the spreading out of hot syrup poured onto a plate. Volcanic shields may be either small or large, and the largest shield volcanoes are many times larger than the largest composite volcanoes. -Caldera-A caldera is a round or oval-shaped low-lying area that forms when the ground collapses because of explosive eruptions. An explosive eruption can explode the top off of the mountain or eject all of the magma that is inside the volcano. Either of these actions may cause the volcano to collapse. Calderas can be bigger than the largest shield volcanoes in diameter. Such volcanic features, if geologically young, are often outlined by an irregula r, steep-walled boundary (a caldera rim), which reflects the original ringlike zone, or fault, along which the ground collapse occurred.Some calderas have hills and mountains rising within them, called resurgent domes, that reflect volcanic activity after the initial collapse. 4-Volcanic Plateaus-Some of the largest volcanic features on earth do not actually look like volcanoes. Instead, they form extensive, nearly flat-topped accumulations of erupted materials. These materials form volcanic plateaus or plains covering many thousands of square kilometers. The volcanic materials can be either very fluid basaltic lava flows or far-traveled pyroclastic flows.The basaltic lava flows are called flood or plateau basalts and are erupted from many fissure vents. Volcano Hazards-Eruptions pose direct and indirect volcano hazards to people and property, both on the ground and in the air. Direct hazards are pyroclastic flows, lava flows, falling ash, and debris flows. Pyroclastic flows are mix tures of hot ash, rock fragments, and gas. They are especially deadly because of their high temperatures of 850 ° C (1600 ° F) or higher and fast speeds of 250 km/h (160 mph) or greater.Lava flows, which move much more slowly than pyroclastic flows, are rarely life threatening but can produce massive property damage and economic loss. Heavy accumulations of volcanic ash, especially if they become wet from rainfall, can collapse roofs and damage crops. Debris flows called lahars are composed of wet concretelike mixtures of volcanic debris and water from melted snow or ice or heavy rainfall. Lahars can travel quickly through valleys, destroying everything in their paths. Pyroclastic and volcanic debris flows have caused the most eruption-related deaths in the 20th century.

Fast Food Industry Marketing Towards Children Essay

Fast Food Industry Marketing Towards Children - Essay Example This essay deeple analyzes not only fast-food market and it's effects on everyday life of children, but also focuses on political and philosophical purposes of such market. The political agenda brings us to identify â€Å"problems† with capitalism: the creation of multinational conglomerates that â€Å"don’t care about its customers†. These require us to ask if the â€Å"harms† this food present morally require government regulation and censorship. Advertising, that is discussed in this essay simply does not have the coercive power which critics allege. Marketing cannot force products upon the innocent, vulnerable, and gullible children. It may be useful to distinguish the advertisement—a simple statement of words—from action in a purchase. The nature of advertising and marketing precludes any possibility of coercion when it comes to persuading children to convince their parents to buy them products which, if used in excess, can be incidental ly harmful. The blame for childhood obesity rates lies with parents and those who control what children eat. The absurdity of the claim that a corporation, constantly concerned with what is necessary for maintaining its very existence, is responsible for what children eat is so obviously absurd that it need not be discussed. In conclusion, claims about marketing to children rely on untenable philosophical doctrines like determinism, misconceptions of persuasive advertising, and mischaracterizations of the adolescent human being are discussed.

Clean room assignment engineering practice Lab Report

Clean room assignment engineering practice - Lab Report Example The next step in the fabrication process is to create the buried channels by implanting phosphorous ions in areas that will eventually be covered by polysilicon gate electrodes. The n-type semiconductor formed by phosphorus contains negatively charged electrons as the primary charge carriers and forms a pn-type diode structure, which serves to localize potential wells deep beneath the silicon/silicon dioxide interface. The potential well illustrated in the central portion of Figure 1 is a schematic drawing of the diode structure. The primary function of the buried channel is to localize integrated electrons away from the silicon/silicon dioxide interface, where they can become trapped during charge transfer. By localizing charge deep within the p-type silicon substrate, transfer of charge occurs more efficiently with a minimum of residual charge remaining in the gate. After the buried channels are formed within the silicon substrate, a layer of silicon dioxide is thermally grown on the silicon wafer surface to provide an insulating base for the gate electrodes. Next, a phosphorous-doped layer of polycrystalline silicon (polysilicon) about 5,000 angstroms thick is grown on top of the oxide layer. This layer of polysilicon comprises the gate electrodes (see Figure 1) and is transparent to visible light, making it an ideal substance for use in CCDs. Although, the fabrication of a complete CCD takes additional steps, the basics of the MOS capacitor assembly have been completed at this point."

Foundation and library services Essay Example | Topics and Well Written Essays - 2000 words

Foundation and library services - Essay Example FLS will be established within foundation campus so as to help students to get their required text books, journals and other printed handouts. FLS will aim at distributing university level books to students and staff of university. The university will deliver a number of courses and the library service will meet needs of students belonging to different streams. The textbooks include media, science, business, literature and many more. FLS will also provide printing services to students in the campus, which is needed quite often. Both textbooks and printing services are directed at UK based students and also internationals students who come to Sunderland for higher studies. FLS also advises international students regarding preparation of student card and accommodation. FLS helps international students to arrange good accommodation facilities and maintain their comfort level in the campus by providing necessary details and rules (Makakane, 2013). FLS will also plan for few activities after classes for students as after a hectic day in classes, they require time for personal needs and relaxation. The activities include free vi deo game and indoor games parlour that will be placed in a separate section from the library. The requirements of the students will be monitored and will be sorted out as soon as possible (Ferrell, 2012). The main vision of FLS is to become one of the leading libraries in Sunderland and gain profit. FLS believes in customer loyalty by satisfying students with services provided, which raises demand for books. FLS is also planning for future expansion into other campuses i.e. London. However, the expansion plan will be executed after three years of its commencement in Sunderland campus. FLS aims at providing wider variety of books to students and staff, which helps them to guide during the course. The library will provide 24X7 services

Adoption of International Financial Reporting Standards (IFRS) in Term Paper

Adoption of International Financial Reporting Standards (IFRS) in European Union - Term Paper Example According to the paper findings the adoption of IFRS in European Union constituted one of the biggest financial reporting alterations in current years and was debatable. The adoption of IFRS results in the use of a universal set of financial coverage standards within Europe, and between Europe and many other countries that require or apply IFRS. This essay declares that the impact created by conversion to IFRS was much bigger and broader than expected. The EU experience states that it affects many areas beyond finance and includes human resources, business operations, IT, customers and external stakeholders. Furthermore, it can be learnt from the EU conversion that IFRS switchover will add considerable intricacy to a range of openings which firms currently pursue. These are mergers or acquisitions, expansion of global operations and new enterprise information systems implementation. IFRS renders companies with a major opening to attain broader transformational change and motor business gains beyond compliance. The economic arguments for the adoption of IFRS are that it is being viewed by many as having very good quality and is sufficient for the task. Indeed there is some empirical research evidence which supports the belief that same standards of financial reporting globally will surely increase market liquidity, reduce tra nsaction costs for capitalists, lessen cost of capital and finally facilitate international capital formation and flows.

The Mediating Effects of Role Stress and Intrinsic Motivation Research Paper

The Mediating Effects of Role Stress and Intrinsic Motivation - Research Paper Example are functions of external rewards and are often carried with the objective of avoiding pain like in the case of punishment or gaining something like in the case of promotions at work. Behaviors that are motivated extrinsically do not give happiness to the individuals in question as he/she acts in that way because of the external rewards. The problem associated with this is that it kills intrinsic motivation, as people get more concerned with the rewards at the expense of enjoying what they are doing (Robinson 2010). There are three types of extrinsic motivation as shown below. Table on Extrinsic Motivation MOTIVATION BEHAVIOR SUSTAINED BY EXAMPLE External Motivation Environmental rewards or punishment contingencies Learning in order to get a job Introjected Motivation Desire to avoid internally imposed remorse and blame Working in order to get money and support family Identified Motivation Desire to express important self-identifications Working because that is what I want to do. Ext rinsic motivation is crude and inefficient because using negative motivation like blackmail and threats or bribing someone to do something does not make him do it wholeheartedly as all the actions are subject to the expected rewards. The problem with this approach is that people are often concerned more with the outcome than the action itself and this leads to high levels of inefficiency (Eskildsen, Kristensen, & Westlund, 2004). These shortcomings can be fixed through using intrinsic motivation as it persuades people to concentrate on doing what they like for internal satisfaction. Intrinsic motivation is therefore the best way of focusing efforts as illustrated below. Intrinsic Motivation Intrinsic motivation can be defined as a type of motivation driven internally and not externally.... The purpose of this research is to examine the relationship between intrinsic motivation and organizational commitment in organizations. The concept of motivation is important when it comes to understanding the behavior of a group of people and finding ways of improving their performance. Motivation can be defined as a force that initiates, controls and maintains behaviors that are goal oriented. This is what propels people to do certain things like eating, working, and socializing. The forces that control behavior can be social, emotional, biological or cognitive in nature. Researchers have come up with different theories of motivation in order to explain the behavior of people and the reasons behind such actions. Intrinsic motivation improves performance more than extrinsic motivation because it is innate. When an individual is intrinsically motivated he/she will perform tasks with the intention of achieving inward satisfaction hence the levels of efficiency will be relatively high er than that of an individual that is motivated by external rewards. At the organizational level, even though the performance of employees is a function of both the environment and innate drives, the innate drives often determine the achievement levels among the employees. This explains the different in efficiency levels among different personnel working in the same environment. Through establishing the relationship between intrinsic motivation and organizational commitment, this paper will provide managers and administrators a better understanding of the behavior of the employees and their attitudes.

Nietzche's Philosophical Understanding of Truth Essay

Nietzche's Philosophical Understanding of Truth - Essay Example However diverse the interpretations of the different scholars may be, they all agree that Nietzsche's philosophy is perspectival. Nietzschean thought claims that there is no singular truth or absolute truth. There is instead a multiplicity of truths. His philosophy states that there is no singular platform or vantage point from which absolute truth could be seen. However, there is also a multiplicity of perspectives, each with their distinct way of presenting the truth. Many scholars have searched for solutions to what appear to be cnradictions arising from Nietzsche's works. This paper however, only aspires to give an interpretation of his thoughts and philosophies. So that the human individual may survive and preserve his condition, given that he has none of the accouterments of beasts armed with the most deadly of natural weapons with which to defend themselves and dominate weaker specimen, Man has resorted to his intellect using the art of dissimulation. It is through "deception, flattery, lying, deluding, talking behind the back, putting up a false front, living in borrowed splendor, wearing a mask, hiding behind convention, playing a role for others and for oneself - in short, a continuous fluttering around the solitary flame of vanity", that Man is able to not only survive but also prevail over other species and his fellowmen. Given that man possesses such a nature, and such nature arises from necessity, it becomes a contradiction that Man should also possess a drive to find truth. Nietzsche states that men do not comprehend the truth through their senses, but merely receives stimuli through them. He is also deceived by his dreams, and does not have a full comprehension of himself since there are many things in his biological constitution that naturally could not be seen. Since Man's nature, mind and his senses and tools of perception do not fully reveal the truth, Nietzsche asks from where does the drive to find truth emanate As an individual needs to preserve himself against others, he also desires their company, being the social being that he is. As such, though he utilizes dissimulation for the purpose of self-preservation, he also tries to eliminate the most flagrant of this method. This compromise gives root to Man's need to find truth. Designations are given to all things and these assignations become the basis for the truths as individuals agree they should be. It is upon these designations that the difference between truths and lies are based. A person who lies is someone who applies the designation or word for one thing to describe another. If this results to harm for another individual or society, then he will be distrusted and even ostracized. Man responds in this way to lies because he is harmed by the commitment of fraud, and not the act of lying itself. It is not deception which is abhorred or condemned but the consequential negative effect it brings upon them. The greater the degree of harm, the more hostile society becomes to the fraudulent person. But the question remains on whether the words used as designations for truths are themselves consistent with what is "absolutely true". Nietzsche describes words as merely "the copy in sound of a nerve stimulus". The more incongruent or distant a word is from the nerve stimulus it is supposed to represent, the more false it becomes. Words therefore are arbitrary assignments which represent

The Tower Bridge Report

The Tower Bridge Report This report will be divided into 5 sections. In the first section I will be describing the function of the company and the product it provides for its customers. The second section will provide an overview of the economics of the business and competition. The third section will describe the management structure at the company. The fourth section will provide both the PEST and SWOT analysis. Finally I will reflect on my time as a tourist guide, describe the job role and give my impressions of the company. Describing the company and what it offers Tower Bridge is a municipal enterprise owned, funded and managed by the City of London Corporation who are the local Government body responsible for the financial square mile. The City of London is therefore responsible for all commercial and operational matters relating to Tower Bridge. Funding of the enterprise comes from a long standing trust. London Tower Bridge is located in the heart of London and is very close to Londons transport infrastructure and world famous historical sites such as; the Tower of London and HMS Belfast. It is a well known bridge that has become an iconic figure of London, spanning the River Thames, and is within walking distance of Londons other famous attractions such as the Globe Theatre and Tate Modern. Originally built in 1894 to ease traffic congestion on London Bridge and designed to allow access to large ships to the pool of London, it was subjected to a major conversion to become a tourist centre in the 1980s. Tower Bride is therefore both a monument to Londons past and a successful tourist attraction. The main offering is the Tower Bridge Exhibition which allows visitors to enter inside the Bridge allowing access to the High Level walkways with uninterrupted views across the city. This provides a unique selling point with which to market itself and provides a memorable and emotional experi ence for visitors. The tour also allows visitors to see the Victorian engine rooms from which the bridge used to be powered by. The company also offers corporate entertainment packages and a popular gift shop for visitors. Entry prices are at an affordable rate and for viewing pleasure, the Exhibition comes equipped with interactive screens, sliding window panels for better picture quality and excellent graphics on their giant screens. One of the most important features of Tower Bridge is its bascule mechanism system, which rises around 1000 times a year and is still in function to this present day. Bridge openings are very popular with the public and are part of its attraction and allure to tourists. This particular bridge is the only bridge in the world of its type that opens and closes. Market and competitors Another historical attraction within the same vicinity as Tower Bridge is the Tower of London, which often competes with Tower Bridge as people tend to mix up the two because the structures are quite similar and this may sometimes lead to confusion. Moreover, the Tower of London was famous in Britain and around the world during World War 2 as an iconic landmark. Inevitably overshadowing Tower Bridge. Nonetheless the Tower Bridge is central to Londons historical heritage as a major commercial port. London has many other attractions including: the London eye, which can have up to 10,000 visitors every day and even the London Bridge Experience which opened in 2008. The Tower Bridge Exhibition has grown steadily since opening in 1984, with last year being its most successful in terms of financial surplus and numbers of visitors. With a small marketing team and budgets, Tower Bridge Exhibition relies heavily on organisations such as Visit Britain/London to document trends in visitors. Tow er Bridge Exhibition targets throughout the year a very broad area including both the European and domestic markets. Within the domestic markets educational groups are also targeted but equal importance is placed on family groups. Advertising normally occurs through specialised magazines, in particular publications like the Times Educational Supplement or via websites such as www.vistislondon.co.uk where costs are generally lower then other mass media options. Trade shows are attended such as World Travel Market where the exhibition is promoted to a range of tour and group organisers and databases are created for direct mail campaigns. Tower Bridge Exhibition has a unique relationship with its competitors, although in direct competition with one another, attractions within London work together along with Visit London to bring people to the area. Tower Bridge Exhibition has a list of distributors which in return for a discounted ticket rate sell tickets globally, however they also pr omote competitors. Other key stakeholders of Tower Bridge Exhibition are Local and National Government and the EU who and impose rules and regulations. The local community and response services, the Tower Bridge charitable trust, all visitors, the media, internal trade unions and employees are also key stakeholders. The cost of visiting the exhibition is  £7.00 per adult and  £3.00 per child (5-15) under fives go free, with a concession ticket costing  £5.00 and disabled guests getting in for free. Group discounts are available for 10 people or more and a promotion with Network rail allows 2 for 1 entry. Ad hoc promotions are run throughout the year targeting specific groups, for example the exhibitions 25th anniversary was celebrated by letting local residents in for 25p. Job role As a Customer Care Guide at the Tower Bridge Exhibition I had a fair amount of duties, roles and responsibilities which was based on the nucleus of customers and their safety along with their well being which meant constantly putting there needs and requirements first at all times. Furthermore, that meant me providing exceptional customer service and care at all times and making sure that the customers visit was as enjoyable and pleasant as humanly possible. With that in mind I would have to posses a certain degree of knowledge regarding the bridge and the local vicinity. I would also be required to have a competent level of expertise relating to the bridges history, construction and design most notably for when I am positioned inside the bridge and doing a position that entails doing speeches regularly. For positions like these I must convey clear and precise information to the customers so that they are made aware of the process inside the bridge. In addition, I would also need to be fully aware of all the processes of the bridge if say there was a fire or an evacuation I would have to be mindful of the correct drills and steps that needed to be taken in order for a safe and secure evacuation to be achieved for all customers especially the disabled, elderly and those in a wheelchair. My duties included maintaining a high level of security for both the visitors and the exhibition items as well as always being on hand and available to interact and engage with visitors should they need or require any assistance or help from me at any stage during there visit. Moreover, if they had a query or wanted further information about the or the area. Management Structure A business structure is very important and every organization has its own structure. A company such Tower Bridge organizational structure is a hierarchical with a concept of subordination of entities that collaborate and contribute to serve one common aim. Most of the staff in Tower Bridge are all in the front office dealing the member of public and tourist, some have more interaction such as the Ticket Office and Customer Care Guides. The mangers Tower Bridge uses a functional structure which has the advantage of being easy to understand. The chain of command requires that an employee can report to one or more managers, but one manger such as Andy Nicholson, typically has more authority over the employee than their other manager(s). In Tower Bridge there are three mangers: one exhibition manager and two assistant managers. Having this structure means having layers of management that control the company by maintaining a high level of authority, with the power to make decisions concerning business activities. Employees such as customer care guide have limited authority to carry something out without prior approval. This organizational structure tends to focus on top-down management, whereby executives at the top communicate by telling middle managers, who then tell first level mangers, who then tell the staff what to do and how to do it. A limited number of employees report to a manager, who then reports to the next management level, and so on up to the Bridge Master or Tower Bridge Director. The managers needs to be responsible for motivating the staffs and ensuring that any formal systems and practices that are in place are not undermined in anyway. In theory the managers at Tower Bridge are responsible for the business performance, as well as maintaining high standards of service and health and safety. A functional structure of Tower Bridge can be illustrated by the following diagram: The Managers are responsible for arranging shifts for their staff, creating promotional events and discount offers, deal with customer complaints, motivating staff, ensuring that staffs have the right uniforms, greeting customers and organising table reservations. PEST Analysis Political Political factors that may affect the ability of Tower Bridge to operate include government and City of London polices. In fact it seems unlikely that these will impact adversely on the attraction in the immediate future given its high profile and historic status. Cuts in public expenditure may lead to higher admission prices and less staff running the exhibition. As the government recent decision to cut funding to Visit Britain by 18% has big consequences for all London Attractions most specifically the smaller attractions such as Tower Bridge Exhibition who relay heavily on its services. Flight and bed taxes could deter visitors away from the city. Terrorism threats threaten the entire London tourism industry. Technology With more people using the internet, Tower Bridge Exhibitions will have to review its current website, as currently ticket purchases are too complicated. Advancements in ICT have meant that statistical data on tourist trends is now simpler to collect and more easily accessible through websites such as Visit Britain. Tower Bridge still has old and new technology some of the original hydraulic machinery is still remain as exhibition in the engine room nowadays they use electro-hydraulic drive that open the bridge up. Economic The main external forces (macro environment factors) that affect Tower Bridge Exhibition are economic and social factors. London is perceived to be an expensive place to visit, so the exhibition will need to provide better value for money. This is possible as at currently utilises only one third of available space. It will need to consider joint promotions with other attractions. Changes in interest rates at home cause fluctuations in disposable income meaning leisure activities are often put on hold, exchange rates and the strong pound against the dollar has seen a smaller spend per person from the important American market. Social Tower Bridge Exhibition relies heavily on family groups, so a decline in traditional family set ups will require Tower Bridge to re-think its family tickets prices. Over the recent years are has been a changes in holiday patterns with people now preferring city breaks and long weekends. Terrorist attacks also cause fluctuations in the market with people looking for safer destinations. SWOT Analysis Strength The business philosophy is not just about making money but emphasizes on educating and informing the public (particularly young people). On the towers walkways, there is a great view of London similar to the Millennium Wheel but not as detailed or exciting. Furthermore, on a positive note, this particular zone is free of congestion charge, which allows people to freely enjoy their journey over the bridge. Although the bridge is funded by the City of London council, it also makes a reasonable income by hiring the venue in the evenings for special occasions. Weakness Although it is an indoor attraction with a large view of London, a visit to Tower Bridge depends on the weather because the best sights are not always available due to the fact of the unpredictable British climate, for instance, on a rainy or overcast day, the views from the bridge can be very poor and distorted which could result in unhappy customers. What is more, London is an all-year-round destination so major attractions are not seasonal. Due to the fact Britain has such unpredictable weather, people usually carry sunglasses and umbrella because they never know what the weather can be like. This could have a bad effect and lead to a bad experience when coming to visit Tower Bridge on an unpleasant day. Firstly, the entrance to Tower Bridge Walkways is confusing for tourists who are unfamiliar with the area as there are no clear signs pointing in the right direction. Also, the journey to Tower Bridge is quite complicated if you have no knowledge of its whereabouts and may get los t. In addition, it is not pedestrian friendly as there tends to be lots of traffic and congestion upon entering the bridge. Secondly, in my opinion their main website is unappealing which doesnt help to attract or interest people into visiting Tower Bridge. This apparent weakness and flaw could have a bad impact on tourists who have never been to London, as the websites layout and structure does not represent or give Tower Bridge an acceptable status (more life and colour in the graphics required to attract online interest). On the other hand, their website has easy access to different links that also caters to childrens needs such as fun packs for childrens discovery which is fun as well as being educational at the same time. Furthermore, to add to criticism the historical building needs substantial refurbishment to help increase the volume of visitors. Although people are aware that it is a bridge, some people are afraid of heights and may feel unsafe or in danger. Moreover, altho ugh the lengths of the walkways are reasonably lengthy, it is quite narrow and may have an affect on those who are claustrophobic. Security measures are paramount for one of the worlds most famous tourist attraction. When entering the Tower there is a single stage of security that visitors must pass through. Once their body has been examined and their belongings are check they are allowed to enter the walkway but it doesnt mean the security level is up to standards. Reportedly, there have been cases where people have entered the building then proceeding through the security check in order to commit suicide. Fortunately, this has not changed peoples views to visit the attraction because any potential suicide incidents have been prevented. In reality, when the bridge does have a scheduled lift this results in a hold up of traffic. It is found that An estimated 38,000 vehicles use the bridge each day, pushing it to capacity during peak hours. This results in many delays for many people , who may decide to take an alternative route to avoid the traffic queues. Likewise, Extra traffic is expected to increase impact damage to the extremities which flex under traffic loads. This could mean that traffic queues are causing damage to the structure of the bridge, which may have a long term affect on the bridge. What is more, it is said that these measures are expected to increase congestion either side if the bridge, adding to delays caused when it opens for shipping. Last year Tower Bridge lifted 925 times. In my opinion, was this necessary? Opportunities Global advertisement could possibly result in an increase in the volume of visitors as many foreigners are unaware of a bridge that opens and this may be an attractive feature to witness in person. Perhaps due to the recession peoples lifestyles are changing, rather than individuals coming to the Tower Bridge they could engage in some promotion and coupons like the two for the price of one, children of the age of under 12 go in for free etc. Other attractions could work together with Tower Bridge rather than competing with them. They could cater for more languages by enhanced displays for overseas visitors such as Europeans and Asians. Provision of tour guides could be encouraged. Even though it is a self-guided exhibition they could offer a guided tour within the ticket price would encourage more visitors and may enhance the quality of the experience. Additionally, they should provide reasonable adjustment to facilitate for people who have disabilities. Due to the fact of the econom ic crisis the value of the pound has decreased. This is good news for the overseas visitors because of the currency exchange rates. In years to come the growth of tourism will increase despite the recession; London will generate tourist revenue from the 2012 Olympic games to be held in this city. This will boost and soar the volume of visitors in the capital. Threat The biggest threat to Tower Bridge is any potential terrorist attack perhaps of more concern is that there is no security check when going through the bridge and anyone is allowed to walk along the bridge. On the other hand, Tower Bridge is surrounded by a high level of competition with other tourist attractions equally famous like the Tower of London. In spite of the fact that other attractions complement each other it is possible that Tower Bridge will lose out due to the fact that it is less appealing. The economic downturn could have an impact on peoples lifestyles and their finances. Another way of viewing this is that the recession has changed our way of life. Culturally and socially people may prefer doing simple things like taking a walk in the park, instead of expensive vacations. After all a large proportion of overseas visitors come to visit the Tower Bridge. As a result this recession could have an significant effect resulting in a decrease of the number of visitors. In c onclusion, it could be said that the current service could continue unchanged. The inherent advantages of location, history and unique appearance will service the attraction well in the future. However, improvements could also be considered namely a more attractive website, cater for different languages, refurbishment of the walkways. The main threats for the future are: economic downturn and limited attractiveness to a young audience. Reflection Working in Tower Bridge has taught me a number of things about how tourist attractions operate in the market and what factors lead to an attractions success. Even though my time at the Tower Bridge consisted of 400 hours work experience I still had to go through the same procedures as I would if I were applying for a permanent job. I was interviewed by Andy Nicholson who gave me a fair amount of information regarding the history of bridge and what they offer to the public. Even through the interview lasted over 3 hours it was very insightful and useful to me. I gained a lot of knowledge about Tower Bridge and its surroundings. When I started work it was the beginning of the Easter holidays. I didnt get any training at first except on how to use a radio. I was thrown in at the deep end for the first three days as I didnt know much but I guess that is the best way to learn. After a few days I was formally introduced to other members of staff and my official training started. The assist ant manager gave me the correct uniform as there are different ones to wear for different positions. I was given a full guided tour and met all the security staff, the maintenance department and human resources. I was shown all the emergency exits as well as all the other exits and where to meet if we had to be evacuated. I was given a radio with my own personal identification which was uniform 13 which enabled me to communicate with other members of staff via the radio. After that I undertook three days of shadowing a full time tour guide and I was also given a big pack of information about Tower Bridge. I learnt 4 different speeches plus aborts and general information of the history of London. A big plus point for me was that I was given the chance to get to know the surroundings and I spent a couple of days visiting other tourist attractions such as the Tower of London, St Pauls Cathedral and the Tate Modern gallery. I thought this was very helpful to me. After 1 week of shadowing and intensive reading I was finally ready to work on my own. My first position was to operate the north lift which takes the customers to the high level walkways and to give them instructions on what to do when they got up there. I did this a few times before trying out the other roles and positions. In total there are 8 positions, 1-3 are working in the lifts and the towers and the customer service areas. The only negative point about this aspect of the job is that it can become very repetitious. Position 4 and 5 involve working in the gift shop next to the Victorian Engine Room. I was lucky to have this experience and to be till trained. Working in the shop has a lot of responsibilities, not only dealing with money and providing customer service, throughout the day youre on your own and this can be quite stressful. There are many duties working at the shop in the morning before opening up, you are required to do a number of duties: making sure that there are enough products on the shelf and that these are neatly presented, knowing whats not available and whats low on stock so it can be ordered in, cash up the money for the till etc. Working in the gift shop can be pleasant but the only difficult issue that I faced was dealing with several customers at the same time. The gift shop is quite a small and confined area and it is where customers exit from the Exhibition. In some cases an unsatisfied customer will use his time in the gift shop to vent his frustrations and whoever i s currently occupying the shop position is usually the one that is on the other end of the brunt of the customers fury. In addition to this, in most if not all the cases of a customer who was not completely happy with there visit and experience and demand a refund or if a technical malfunction occurs to any of the penny press machines then it is at the gift shop where all of the would be resolved. Positions 6, 7 and 8 are what the company refers to as footfall enticement. These duties are intensive and consist of you dealing with customers at the front of the ticket office who are visiting the Tower Bridge Exhibition or are just walking pass as well as giving out general information about the bridge. I think the footfall position is a crucial role as it represents the Tower Bridge image and they are the first staff and port of contact to interact with the customers before they enter the exhibition. Throughout my work placement I have undertaken a fair amount of footfall and my view upon it is that it can be quite enjoyable. The only downside is that the footfall is an all year position which I think is unfortunate because Tower Bridge is on the river it can very windy and during autumn and winter it can be very cold. I did a few footfalls in April and even so it was extremely cold for me to endure and for someone to do this position you have to be mentally and physically stron g. I dont think people should have to work 8 hours outside in such cold conditions most notably during winter times and I think they should use the footfall personnel to go onto the walkways to give talks about the bridge and have one at the gift shop for assistance as the shop can get very busy and hectic at times. After 200 hours I was given the opportunity to work at the Monument. My job role was to give out leaflets to those who completed the 311 steps and give brief talks about this famous landmark. I had a lot fun working there because it was a more intimate setting than the bridge so you got to talk and engage more with your work colleagues. It also meant that you could immerse yourself more in depth with the visitors and ask them more about their visit to the capital and how long they were intending on staying and where they were originally from. There is so much history written into the Monument which is intertwined with the Great Fire of London so for me to work there and to be a part of it was a good experience which contributed to my enjoyment there. In terms of organization and structure there is much to change and develop. What surprised me is that staffs do not really work together and in some ways work in isolation from each other which seems inefficient and ineffective. There tends to be a gap and divide between the permanent staff who have been employed there for many years and the temporary staff such as myself. Conclusion Overall working at Tower Bridge has been a good learning experience for me. Like any other job there will always be positives and negatives but in some ways the work has provided some unique insights. I think Tower Bridge and the Monument are very successful tourist attractions for the reasons stated previously and there is no reason why it should not continue to prosper in the future with the right investment and a culture of continuous improvement. Many people who work at Tower Bridge have provided years of dedicated service for a prolonged period of time. Tour guides, ticket office, managers, security and maintenance people have worked their for a long time. A large proportion of them are 40 plus in age which is a change for me because it is the first time I have come across a situation like that. I think I have picked up some of their characteristics and learnt a lot from their experiences of being at Tower Bridge. On the whole I had a great experience and I would highly recommen d it to other students who are interested in the tourist industry or those people who like history. Out of all the places I have worked in previously I can honestly say that this was the most interesting job and role that I have ever experienced. The majority of the staff I built and formed a relationship with not only as work colleagues but as friends outside working hours.

On Wed., 7-24-91, I, Det. KENNEDY on Squad 126, while interviewing the suspect in this offense, that being one Jeffrey L.. DAHMER, spoke to him in regards to the fact that he had knowledge to whether or not the acts he was comitting were right or wrong. At this time, Mr. DAHMER stated that he was fully aware that the acts he was colTiflitting were wrong and that he feels horrified that he was able to carry out such an offense. He stated that it is obvious that he realized that they were wrong because he went to great time and expense to try to cover up his crimes.

Application Security Essay -- Technology, Programming, Video Games

According to [3], game design refers to â€Å"something to program about.† When creating games, one must take into account the flow and structure of a game. These cannot be ignored since a domino effect follows: poor design will lead to a poor implementation of the game. A poorly implemented design would then lead to a program that is vulnerable to both simple and complex attacks. [1] mentions that loopholes or bugs in games may occur as a product of poor game design. This brings another point: poor design can lead to exploits. Bugs (in games) are more often than not exploited in order to gain some sort of virtual good or advantage, rather than being reported to the developer for further improvement. [1] also discusses different forms of cheating, some of which can be attributed to a poor design. These forms of cheating may include (as an example, for online games) hacking a server or database to gain an advantage, or hacking a system itself to extract valuable information, a mong many others. With respect to offline games, [4] describes an exploit which could affect others’ game play. Theoretically, one would assume that offline games would not affect others’ game play since, there are no networks or servers or connections to the internet, unlike online games. However, for offline games, it is possible for two users to share the same system, and therefore share the same game but with a difference in the saved game file though. The sum of it all is that a game developer’s poor design could be a â€Å"portal† for exploitation. There are ways though to improve design. One may review the design over and over again, from all perspectives, to ensure that there are as minimal â€Å"flaws† as there can be, since these flaws cannot totally be eradicat... ...VA, programmers must take into account the access modifiers of their classes. Preferably, programmers must make class’ attributes private and make use of getters and setters [9]. Use the protected access modifier for superclasses so that its subclasses can access it. Anticipate exceptions that might come along the way and use proper exception handling to avoid bugs that attackers may exploit. Encryption has always been one of the best ways to secure data. Always encrypt sensitive data like passwords and game assets. All in all, the techniques mentioned above are just some of the techniques one can use to secure his or her game. One can use whatever technique as long as it will help improve the security of his or her game. What’s important is to know security threats that pose risks to your game and be able to implement proper techniques to address these issues.

Breakfast of Champions Essay -- essays research papers

Breakfast of Champions   Ã‚  Ã‚  Ã‚  Ã‚  Have you ever read a book and enjoyed it, but once you were finished you wondered what it was really about? You wondered if the book had a deep meaning that you had to sit and think about or if the book was just for entertainment purposes only and had no meaning whatsoever. For me, Breakfast of Champions by Kurt Vonnegut Jr. was this type of book.   Ã‚  Ã‚  Ã‚  Ã‚  Breakfast of Champions is a story about two men who are going to eventually meet each other at a festival for the arts. The story tells about their journey in detail and explains how each man perceives and reacts to society.   Ã‚  Ã‚  Ã‚  Ã‚  Dwayne Hoover, a Pontiac salesman, is on the brink of insanity. Dwayne is a very â€Å"well-to-do† man and owns many businesses in Midland City where he resides. In the blink of an eye Dwayne’s life changes forever. One day Dwayne’s wife drinks Drano and is killed. After this incident Dwayne’s body starts producing â€Å"bad chemicals† which causes him to become insane.   Ã‚  Ã‚  Ã‚  Ã‚  The other main character of this book is a man by the name of Kilgore Trout. Kilgore is an interesting character. â€Å"Trout,† as he is referred to in the book, is a lonely person who thinks everyone in the world is against him. Trout lives by himself and sells screening and siding for houses. Trout’s best and only friend is his bird named Billy. Trout is a struggling writer whose work is mainly published in pornog...

Mark Twain and William Hazlitt’s Comparison

Ideas can be conveyed in many different ways dependant on the tone, style and diction of the piece. Both William Hazlitt and Mark Twain present a very similar topic in two very different ways. Hazlitt†s â€Å"Education of Women† speaks of how classical education is not proper for women. Twain†s â€Å"Female Suffrage† reiterates the idea that women should not be able to vote or hold public office. Hazlitt†s 1815 essay is a true opinion of his own feelings against having educated females. 1867, a different time with similar ideas, is the setting of Twain†s piece. He portrays how the relationship between suffrage and women is completely ridiculous. These authors use different styles to display completely opposite points. Hazlitt wastes no time getting to his point in order to drive it into the minds of the readers. He intends that his audience is only the educated male society. Hazlitt feels that women do not need to be anything more than generally educated. He attempts to convince his audience to accept his views and practice them. Twain, on the other hand, is creating a humorous situation which picks at the number of crazy positions that his wife holds in the community. He is not trying to make the audience think that female suffrage is bad. Twain intends that all people will read his piece for comic relief. Hazlitt uses a very straightforward type of diction in his essay. He explains his points and backs them up with his own opinions and observations. He is very authoritative and arrogant in the way he speaks. â€Å"They are mere egoists. They have no passion for truth, nor any love of what is purely ideal† He feels that his way is the right and only way to think. Since he speaks unto the educated community, he uses well-accepted ideas to communicate his points. Twain uses hyperbole, an approach very different from Halzitt†s style. Twain takes the offices held by his wife and exaggerates them to a humorous level. His diction is very relaxed and calmed. The tone Twain tends to adopt can be misinterpreted as self-centered, but his intent is only to bring a sense of fun to the audience. Hazlitt†s effect of style is very powerful. The essay is very convincing and if it is read to establish ideas, it is nothing short of excellent. The way he compiles the words with his diction, makes the points in his essay incredibly moving. When read by the desired audience, this piece is quite moving and powerful. If a female reads this, the expected reaction is a sense of loathing. Twain accomplishes his goal of being humorous and entertaining. His combination of creative ideas with a serious topic displays his great deal of writing skills. The reader is torn between believing what Twain writes and seeing the humor of hyperbole. The reader is very amused by the decisions that have to be made on interpretation. Hazlitt and Twain use different style, tone and diction to explain to readers their feelings on touchy issues. Hazlitt uses very powerful and persuasive ways of speaking to convince his readers that the education of women is completely unnecessary. Twain is quite entertaining to read because he pokes at his wife†s positions. He assumes that the reader will identify that he is only attempting to entertain his audience. Both authors are very different in style but by using different types of writing, they prove totally different points with the same subject.

Nadine grodimer’s The train from Rhodesia

Nadine grodimer's The train from Rhodesia BY jzy240 Nadine Gordimer's nobel prize speech To sum up the speech, Nadine Gordimer is saying that humans as a species are natturally inquisitive and are constantly advancing. We always want the answer to all the questions. That we have evolved to communicate to find these answers quicker. Yet we may not be able to find these answers. This is where fantasy and myth can gives us the answers to compincate for the lack of the truth. They combine what is known and what we want to know. That writing and life go hand in hand with achother.Metaphorical language in The train from Rhodesia Throughout the short story the train itself is a metaphor. Not easily-envisioned one yet a metaphor all the same. It is mentioned to be a beast. For example â€Å"the steaming complaint of the resting beast†. The use of the word beast represents the train as uncontrollable and aggressive. Also the sound of the trains whistle is an eerie sound, like the howl of a wolf. The train isnt Just an out of control beast, it is like a chained beast. It was â€Å"blind and pulled helplessly' such as an oxen pulls a farmers plough.However for all its anamalistic qualities the train is given the human qualities. An example would be when the train calls out â€Å"I'm coming† is saying that the train is able to speak, therefor giving it human qualities. The train cries out â€Å"and again there was no answer† this represents humans and how they have been calling out throughout the centuries to o avail. We called out in prayer in song and in many other ways, yet no reply from anything, other than humans, came back. The train then mocks mans forever desire for an omnipotent creator, or at least an answer.

Experiencing the Teaching-Learning Process Essay

Course Description This Field Study course 2 is designed to provide FS students with opportunities to connect teaching-learning theories and principles discussed I the six-unit courses in Principles of Teaching 1 and 2 with actual classroom practice. It is intended to help the FS student observe how these principles of teaching and learning are applied by the resource teacher to make the teaching-learning process interactive, meaningful, exciting and enjoyable Field Study can be anchored on the following Professional Education subjects. Principles of Teaching 1 and Principles of Teaching 2 Educational Technology 1 (partly) Objectives 1. Arrive at an experiential knowledge and understanding of the principles of teaching and learning 2. Reflect on the application of the principles of teaching and learning for meaningful and lasting learning 3. Determine how the guiding principles in lesson objective formulation are applied in the teaching-learning process 4. Acquire the skill in developing cognitive skill and value lessons meaningfully and interestingly by an in depth treatment of the subject matter and by integrating thinking skills. 5. Apply the guiding principles in the selection of teaching strategies. 6. Identify the teaching approach employed. 7. Trace the logical development of a lesson. 8. Identify effective questioning and reacting techniques. EPISODE 1 – PRINCIPLES OF LEARNING Name of FS Student______________________________________________________ Course________________________ Year & Section____________________________ Resource Teacher 1_____________ Signature_______________ Date Resource Teacher 2_____________ Signature_______________ Date Resource Teacher 3_____________ Signature _______________ Date Cooperating School______________________________________________________ My Target When I observe three different classes. I will be able to identify application of the principles of learning in the teaching-learning process. Observation Sheet Name of the Resource Teachers Observed: Muriel Criselda Delmo School Address: B 1 L3 Panorama Ville Mariquita Sta Rosa City Laguna Grade/Year Level: Kinder 1 Principles of Teaching Teaching Behavior of the Teacher/ Learning Behavior of the Learner as Proof of the Application of the Principles of Learning 1. Learning is an experience which occurs inside the learner and is activated by the learner 1. The teacher lets the learner do the learning activity 2. Learning is the discovery of the personal meaning and relevance of ideas. 2. This is somewhat the same with principle number one. Learners can easily understand concepts if these are relevant to their needs and problems. Hence, as teachers, we must relate the lesson to the learners’ needs, interests and problems. 3. Learning is a consequence of exercises  use experiential learning as much as possible period 4. Learning is a cooperative and collaborative process.  Learners will learn more if they are given chances to work together and share ideas. Make use of group activities. 5. Learning is a evolutionary process  Learning especially if this means a change in behavior does not happen in a click. This requires time and diligence. So as teachers, is patient? Be patient. Be patient. Be patient. 6. Learning is sometimes a painful process This means that learning requires sacrifice, hard work, study time. Let the learners realize this okay? 7. One of the richest resources for the learning is the learner himself Let’s not be too â€Å"centered† upon ourselves. Let’s draw the discussion not only on our own experiences as teachers but on the learners’ experiences as well. Listen and let the learners share their prior knowledge, stories, information, etc that can enrich the learning process.  Encourage free sharing inside the classroom. 8. The process of learning is emotional as well as intellectual Learners can’t learn that much if they have something that is bothering their minds. These can be problems and worries they have either in or out of the classroom. Thus, as teachers, let us be sensitive to our students’ problems. We can’t teach learners with empty stomachs remember? 9. The process of problem solving and learning are highly unique and individual Make use of different teaching strategies that can cater multiple intelligences and learning styles. My Analysis 1. What is the impact of the resource teacher observance of these principles on the teaching-learning process and on the learners? 2. Which learning principles was applied most? 3. Which learning principle was applied least or not applied? Do you agree with these principles of learning? Or have you discovered that they are always correct. My Reflection 1. My reflections on my observation of my teacher’s observance of these principles. Did my Resource Teacher adhere to these principles. 2. Lesson I have learned from my observations on the classroom application of the principles of learning. EPISODE 2 – LESSON OBJECTIVES AS MY GUIDING STAR Name of FS Student______________________________________________________ Course________________________ Year & Section____________________________ Resource Teacher 1_____________ Signature_______________ Date Resource Teacher 2_____________ Signature_______________ Date Resource Teacher 3_____________ Signature _______________ Date Cooperating School______________________________________________________ My Target In this Episode, I must be able to: Deduce the lesson objectives after observing my Resource Teachers teach. See how the guiding principles in the formulation of lesson objectives are applied Realize the importance of a clearly defined lesson objective. 1.As I observe a class, I will use the observation Sheet for a more focused observation. Observation Sheet  Name of the Resource Teachers Observed: Muriel Criselda Delmo School Address: B 1 L3 Panorama Ville Mariquita Sta Rosa City Laguna Grade/Year Level: Kinder 1 Guiding Principles in Determining and Formulating Learning Objectives Teaching Behavior which prove/s Observance of the Guiding Principle 1. Begin with the end in mind 1. The resource teacher began her lesson by starting her objective 2. Share lesson objective with students 3. Lesson objectives must be in the 2 or 3 domains – cognitive, skill and affective or cognitive and affective or skill and affective 4. Work on significant and relevant lesson objectives. 5. Lesson objectives must lead to the development of critical and creative thinking 2. After observing your resource teacher teach, write down what you think was/ were her lesson objective. 3. Ask permission from your resource teacher for you to copy her lesson objective for the day’s lesson. Copy it here then compare it with your answer in #. Are they the same? Different? My Analysis 1. If answer in # 3 above is different, what is your conclusion regarding written lesson objective and actual lesson development? Are the lesson objectives in the lesson plan always followed? Do they really serve as guiding star? 2. Why did you find it easy/ Difficult to write down the resource teacher’s lesson objective for the day? Did he mention it at the beginning of the lesson? 3. Did you find the lesson objective SMART? Why or why not? 4. Was the lesson objective in the cognitive or psychomotor or affective domain? Or was it in two or three domains? Support your answer. My Reflections Any lesson learned or insights gained from your observations focused on lesson objective? Write them down here. Are lesson objectives truly the guiding star in the development of a lesson? Or are lesson objectives sometimes forgotten as the lesson develops.

Nonpoint Source Pollution

Nonpoint source pollution is land runoff from drainage, rain, and seepage and hydraulic modification. It is caused by rain or snow melt that moves through and over the ground. When the runoff moves, it collects and picks up manmade and natural pollutants and ends up spilling into lakes, rivers, streams, and coastal waters. Nonpoint source pollution can include things like motor oil, toxic chemicals, animal droppings, trash and even insecticides. Our drinking water needs to be protected. It takes the help of the community, public water systems and resource managers.We can do small things such as posting signs in our community to let others know that any pollution in the area can contaminate our everyday drinking water. You can also be careful as to how much fertilizers and pesticides you use because the more you use, the more runs off when it rain and it is in the soil as well so when the rain washes the soil, it flows through storm drains. A great plan is to get a group together and help clean up along local rivers and streams and along side of the road.It helps to limit the trash and bacteria that contaminates our water. Other solutions to help prevent non point source pollution and help keep our water clean is to keep all harsh chemical substances stored away from the ground and in their original containers. Also, If you happen to wash your car, don’t allow the runoff to drain into the streets or the sewage system as it will contaminate it. Opposing views of these issues are perhaps people not agreeing to get up and go volunteer because they have better things to do.Some people see it that the city is supposed to take care of it. Some people won’t want to change the location of where they wash vehicles at. They all want convenience of course. Many people do not have proper inspections of their lawns that have been fertilized. They can be tested by professionals but people will oppose to because it will come with a fee, and others do not have the ir septic tanks cleaned out every few years because of the price as well.Non point source pollution also contributes to eutrophication which is runoff that has nitrogen and phosphate in it and it stimulates the growth of algae and it can harm and kills fish and organisms. The algae grow to make a mat over the water and on the floor of the water that diminishes the light through the water so it lowers the growth and productivity of other plants. â€Å"The water becomes depleted in oxygen. When the abundant algae die and decompose, much oxygen is consumed by those decomposers.Oxygen in the water is also lowered by the lack of primary production in the darkened, deeper waters. Lowered oxygen results in the death of fish that need high levels of dissolved oxygen such as trout, salmon and other desirable sport fish. The community composition of the water body changes, with fish that can tolerate low dissolved oxygen, such as carp predominating. As you can imagine, changes in fish commun ities have ramifications for the rest of the aquatic ecosystem as well, acting at least in part through changes in food webs. (Muir, P. 2009)Some challenges that my plan faces is that it’s not very easy to get others to partake in community service and to also notice the small things they do really contribute to non point source pollution in my community. It takes a group effort to raise awareness on this issue, but if everyone pulls together, our drinking water will be cleaner, our lakes ponds and rivers will be safer to swim and fish in and the plants and animals in the habitats of our waters will be safer and not endangered by our hazardous wastes.This plan effects the entire community and can become a very productive and positive way to protect our environment and ourselves. Our children drink the water we contaminate, even though it has passed through water treatments, it is still not clean enough to drink safely. We can also consider raising awareness groups and contact ing your local news stations to get the word out to your community and also have your coworkers get involved as well.
