Global warming and people going green Essay

The natural environment is the place of all life and non life beings. Natural resources are available to human existences without clear cut boundaries in the natural air. H2O and clime. Natural environment has a beginning of energy. radiation and electric charge and all these are non as an influence of human activity but by the bing nature of our planet. It is the huge creative activity that makes adult male enjoy and take pleasance and hence demands to prosecute in preserving and heightening the natural environment. Great challenges have faced our natural and original environment and accordingly devastation. pollution. and loss of life has been seen to happen through the influence of human activity. Pollution in the air. H2O. and in the environment in general has been apparent through the burning of fuels and other non reclaimable stuff. Water. land and air have non been conserved and this poses a great danger on the bing ecosystem. Man’s interferance has threatened the being of species and has led to some of them being endangered or nonextant. This is a direct impact that shows that adult male has had discourtesy of biodiversity and ecosystems in which human existences and other life beings depend on. Human’s activities have been linked to be an environments large challenge. The release of C dioxide from green houses has been on focal point as this is a human and natural environments interaction with gases has caused clime alteration. These strong concerns are associated to greenhouse gases that cause climate alteration. Global heating has been associated to the rise in the temperature on the earth’s air and oceans. Large heat capacity on oceans have caused the sea degree to lift and do utmost conditions alterations. As a consequence of such environmental concerns assorted authoritiess have signed the Kyoto protocol so that they can be after on cut downing green house emanation. hypertext transfer protocol: //www. globalissues. org/EnvIssues/GlobalWarming. asp It is of import at this occasion for adult male to understand that he has a direct influence to the alterations that occur on the Earth surface and should take cautiousness about them. Climate may alter but non entirely by atmospheric concentration of C dioxide from green houses. The ascription of planetary heating can be linked to the industrial epoch where adult male has been vigorous in their activity and have had no cognition on the impact they have to the natural environment. The soaking up of atmospheric gases contributes to warming the lower ambiance and surface of the planet. During the soaking up and emanation procedure of infrared radiation warming occurs. ( Weart 2003 ) . Water vapor. C dioxide gas. methane and ozone are the major green house gases responsible for the heating effects. This is attributed by increased human activity in the industrial revolution such as agribusiness. green houses. motor industries among others. deforestation. One among the greatest human activities that have markedly increased gas emanation is the combustion of dodos. Use of dodo fuel is therefore seen to be lending factor with such dodos fuel militias increasing their emanations through the increased and extended usage of coal and pitch littorals. Evaporated H2O signifiers gas in to the ambiance and as a consequence more H2O evaporates and hence there is more consequence than due to carbon emanations entirely. From the clouds. emitted infrared radiation exerts a warming consequence and when they reflect sunlight they emit infrared radiations that have a chilling consequence. ( Weart 2003 ) . Temperatures were comparatively stable before 1850 but gradual addition in sea temperature than on land is a natural phenomenon. Land has an effectual heat capacity as compared to the oceans which loose heat more readily. Forest glade and Asiatic rice irrigation are human influences that William Ruddiman argued that planetary clime was influenced by these activities. hypertext transfer protocol: //www. incredulity. net/global_warming Global heating consequences to planetary retreat and sea degree rise. The addition in planetary temperatures can take besides to north-polar shrinking and marked pattern alterations in the rainfall. As a consequence inundation or checkerss are a common consequence of the planetary heating. These are utmost conditions events. Death of animate beings and immensely the devastation is really tremendous. Floods and drought seasons cause low agricultural output as endurance of workss is so compromised and the life of animate beings is at interest with addition in diseases. With such catastrophes. inauspicious wellness effects. supplanting and utmost economic losingss destabilize the normal life of the people on planet Earth. hypertext transfer protocol: //www. incredulity. net/global_warming Human activity have great reverberations on their life with the possible decrease of ozone bed and happening of hurricanes and other pelagic interventions that make favorable. the spread of malaria and dandy fever febrility. With political and societal arguments traveling on. hapless parts such as Africa risk the effects of planetary heating. The developed universe and particularly the western portion have accepted the thought that human influence is the major influence to climate alteration. Assorted states now weigh the benefit that would ensue when industrial emanations are limited against the cost they would incur when they adopt new alterations. For the interest of recovering back the natural environment. alternate energy beginnings should be embraced and given opportunity for observation. Vigorous runs that teach on the consequence of planetary activities and stress on adaptation of stricter steps that would cut down gas emanation should have support worldwide. India and Chinas have a batch of C dioxide emanations and the U. S. every bit good. However. worthwhile thoughts and dedications have been recorded in the U. S which is willing to bear the cost and cut down its C emanation. hypertext transfer protocol: //www. globalissues. org/EnvIssues/GlobalWarming. asp Many alterations are bound to be realised with the day-to-day effects related to planetary heating. There is so much uncertainness about other warming marks that may be associated to human activity and ensuing to temperature addition. Vector borne diseases are bound to increase due to the migration of the insects from the north parts and particularly due to the consequence of the warmth addition. As it was recorded in 2004 and 2005. black hurricanes were attributed to the heater Waterss on the ocean and no 1 can expect if they will patronize or be stronger as they hit the parts. ( Leroux 2005 ) As a consequence of planetary warming serious checkerss will hold people suffer and particularly Africa and in Europe. In general. the effects of planetary heating can run out the economic system at a state as they try to reconstruct damaged substructure. remedy diseases and seek to pull off such environmental struggles. Though planetary heating has been attributed to other activities that do non associate to adult male. the major intercession by adult male would be to cover with those that are in their control. Solar fluctuations. volcanic eruptions. orbital forcing. glacier retreats and disease vectors may be associated be causative agents to increased temperature. But a critical expression at it lives the inquiry. Should adult male be nescient of his activities on the Earth? hypertext transfer protocol: //www. canadafreepress. com/2007/global-warming020507. html Man should be at the bow forepart. looking for solutions instead than warranting their non- part to the planetary heating. Small and big graduated table preventative steps can be put in topographic point to assist forestall farther injury and make a better topographic point for our kids to populate in. Without green house emanations temperature would be endurable and more hospitable. Use of fossil fuels used to run autos. heat places and concerns should be under cheque so that carbon dioxide concentration is reduced. In this breath. usage of gas. gasoline and Diesel as used in crude oil merchandises should be reduced. In the same manner that adult male has been able to impact the planet. they should be able to consequence alteration through alteration of practise. They should do usage of fuel-efficient autos. cut down travel errands. and utilize alternate agencies of conveyance like walking or merely working from the house. At place. one should take at utilizing energy salvaging contraptions and illuming stuffs. A great trade of deforestation. industrial activities. excavation and agricultural addition has led to gas emanation. As a scheme. trees should be planted and deforestation stopped. Deciduous trees should be planted as they contribute to taking 50 lbs of C from the air yearly. Industrialization should be minimized and compost cavities made for waste disposal such as foliages. Ignorance about planetary heating should be a forgone phenomenon and adult male should wake up to the call of reconstructing the already damaged environment. Air. H2O systems and the environment have degraded and the issue at manus is to come on and change by reversal the eroding that has already taken topographic point. It is of paramount concern. that adult male should non take opportunities to affect themselves in activities that compromise the planetary call to forestalling planetary heating. The hazards involved in planetary heating are far stretching and the effects can be felt for a life-time. As per the United Nations millenary development ends. work outing the environmental job will be regarded as eliminating poorness. Mankind should take to cut down dodo fuel imports and continue the ecosystem through increased consciousness runs that address the clime alteration issue. Citizens and companies should encompass anti pollution and planetary heating bar steps. ( Pringle 2001 ) Policies at local and national degree should be put in operation so that single activities are governed and implemented at province degree. Why would adult male non be willing to do a better topographic point for him and coevalss to come? The major measure to understand that forestalling C emanation is one of the cheapest intercessions that adult male can utilize to halt the threat. Invention in new engineering of autos and major power workss should hold a 2nd idea on the deduction it has the hereafter. All in all adult male should through accustomed pattern. salvage energy and have another option to utilize of fossil fuels. In 1990 to 19995. El Nino was a force per unit area release that was linked to planetary heating. Heavy rains pounded and several thousand displaced by inundations. Death of human and of farm animal marked the season. Beside such conditions events hurricanes have claimed life. caused devastation and economic loss. hypertext transfer protocol: //www. globalissues. org/EnvIssues/GlobalWarming. asp Why would adult male be willing to put on the line more? It is the responsibility of all adult male to transport aggressive runs and appreciate the fact that they caused it to go on and they can do it alter for better. With dedication and motive. such calamities can be long forgotten as they work on towards one end of forestalling planetary heating and reconstructing the debauched environment. Its effects are black but our control is the manner frontward. Plants Cited Ball T. Global Warming. worlds. Carbon Dioxide. The Cold. Hard Facts.

Golden country â€Å"Presumably she could be trusted to find a safe place. In general you could not assume that you were much safer in the country than in London. There were no telescreens, of course, but there was always the danger of concealed microphones by which your voice might be picked up and recognized; besides, it was not easy to make a journey by yourself without attracting attention† An old, close-bitten pasture, with a footpath wandering across it and a molehill here and there.In the ragged hedge on the opposite side the boughs of the elm trees swayed just perceptibly in the breeze, and their leaves stirred faintly in dense masses like women's hair. Surely somewhere nearby, but out of sight, there must be a stream with green pools where dace were swimming? It was in the sun, they in the shade. It spread out its wings, fitted them carefully into place again, ducked its head for a moment, as though making a sort of obeisance to the sun, and then began to pour forth a torrent of song the rented roomWhat appealed to him about it was not so much its beauty as the air it seemed to possess of belonging to an age quite different from the present one. The soft, rain-watery glass was not like any glass that he had ever seen. The thing was doubly attractive because of its apparent uselessness, though he could guess that it must once have been intended as a paperweight. It was very heavy in his pocket, but fortunately it did not make much of a bulge. It was a queer thing, even a compromising thing, for a Party member to have in his possession. There was a small bookcase in the other corner, and Winston had already gravitated towards it.It contained nothing but rubbish. The old man was standing in front of a picture in a rosewood frame which hung on the other side of the fireplace, opposite the bed. Winston came across to examine the picture. It was steel engraving of an oval building with rectangular windows, and small tower in front. It seemed vaguely f amiliar. Winston wondered vaguely to what century the church belonged. It was always difficult to determine the age of a London building†¦. One could not learn history from architecture any more than one could learn it from books.Statues, inscriptions, memorial stones, the names of streets — anything that might throw light upon the past had been systematically altered. Winston lingered for some minutes more, talking to the old man, whose name was Charrington. All the while they were talking the half-remembered rhyme kept running through Winston's head. ‘Oranges and lemons say the bells of St Clement's, You owe me three farthings, say the bells of St Martin's! ‘ It was curious, but when you said it to yourself you had the illusion of actually hearing bells, the bells of a lost London that still existed somewhere or other, disguised and forgotten†¦ et so far as he could remember he had never in real life heard church bells ringing. He got away from Mr Char rington and went down the stairs alone. He had already made up his mind that after a suitable interval – a month, say – he would take the risk of visiting the shop again. Yes, he thought, he would come back. He would buy further scraps of beautiful rubbish. He would buy the engraving of St Clement Danes, take it out of its frame, and carry it home. He would drag the rest of that poem out of Mr Charrington's memory. Even the lunatic project of renting the room upstairs flashed momentarily through his mind again.

Quality Management for Organizational Excellence: Total Quality Pioneers Essay

In this paper, Philip Crosby will be discussed as one of the pioneers of total quality. Quality will be defined and also total quality will be discussed about how each contributed to Philip Crosby’s success. Additionally, it will be explained why quality is useful in today’s business environment. Quality and Total Quality Defined In today’s world the majority of consumers require their products and services have quality. Quality is performance to the standard expected by the customer, meeting customer needs the first time and every time, doing the right thing right the first time (Goetsch, 2010). Quality is defined as â€Å"a dynamic state associated with products, services, people, processes, and environments that meets or exceeds expectations and helps produce superior value† (Goetsch, 2010, p. 5). The dynamic state of quality will change in the future as time goes on. Total quality is the collective quality concepts pulled together as one comprehensive approach to conducting business (Goetsch, 2010). Total quality is achieved through strategy, obsession with quality, teamwork, education and training, employee involvement, and customer focus in addition to many other aspects of quality. If any element of total quality is not present, then total quality has not and cannot be achieved. Philip Crosby Philip Crosby was a director for ITT Corporation for 14 years until 1979 when he opened his own company called Philip Crosby Associates. Philip Crosby Associates was an international consulting firm on quality improvements for businesses. Crosby defined quality as conformance to requirements and was known for his theory of zero defects management and prevention. Crosby also introduced Quality Vaccine that consisted of three ingredients: 1) Determination, 2) Education, and 3) Implementation. Many companies and managers also use Crosby’s concept of â€Å"doing it right the first time† (Boti, 2011). With conformance to requirements, quality is considered customer satisfaction and compliance with certain standards is required. Crosby’s zero defect management sets the standard that errors are not tolerated, and there are no acceptable levels of non-quality; hence doing it right the first time (Boti, 2011). Prevention, as Crosby describes, is â€Å"quality should not be controlled, it must be done† (Boti, 2011, pg. 205). Last, quality measure is the cost of non-compliance with quality. Quality Today and the Future Organizations that apply Crosby’s quality management concepts to their business strategies have demonstrated they can remain successful in the business environment. Crosby’s values of understanding the importance of employee and customer education have helped to create consistency in quality, increase productivity, increase profitability, and customer satisfaction. Companies using outdated management approaches are missing opportunities for innovation and growth. Organizations that understand and embrace the dynamic element of quality management will be prepared for the ever changing environment and unknown circumstances that may arise. The future for businesses that have managed the trends in quality will have a better competitive advantage to those who do not. Conclusion Elements of quality may differ from person to person and is constantly changing. Organizational awareness of changes is essential to remain competitive and necessary to produce a better quality product. Long-term success of a business is driven by quality and an organizations ability to continuously improve the quality of its product or service.

Different Challenges to Different Organization Research Paper

Different Challenges to Different Organization - Research Paper Example The Credit crunch means the economic return of the overall company curtails due to the number of factors. This could be because of the recession where the overall business activity slows down. This result in low purchasing power of the consumer and those companies which specialize in luxurious items faces major hit back. This results in low demand, low sales, and low profit and overall low earnings by the companies. Due to global warming, many changes have been occurring slowly and gradually which affects adversely the company's position and stability. For those companies which are involved and specialized in tourism-based services especially on beach locations greatly affected by such crucial natural situations. Climate Change means the rapid increase in the temperature of the world which leads to other climatical factors. These factors are an increase in intense cyclones, air temperatures, and a rise in water level in the sea. These are the challenges faced by tourism countries. Any company no matter what kind of business it deals with, are equally liable for some social responsibilities. It means that the company should meet some corporate regulations, international norms, and ethical standards. Business should promote the best interest of the public and should be for the growth of the community. It should be responsible for all those activities which have impacts on the environment, communities, employees, and consumers. The company should not be deliberately involved in illegal or harmful practices. BUSINESS ETHICS CHALLENGE: Business ethics means that the company follows ethical principles while engaged in business activities. It applies to the conduct of business as a whole and as an individual. It applies in all fields such as medical, technical, legal and others. In this 21 century, the demand for business ethics in process and actions is increasing. The new public initiatives and laws are introduced to bring improved business ethics followed by the business and avoid short term gains by acting in unethical ways. Â

Evaluation in human services Essay Example | Topics and Well Written Essays - 1000 words

Evaluation in human services - Essay Example Additionally, the staff may fear negative effects that evaluation can have on their employment. This negative implication of evaluation can include lost jobs for employees perceived to have underperformed or due to restructuring those results in elimination of some organizational functions and therefore role of some employees. Employees might also fear evaluation as it might result in increased workload for them especially when there is merging of some functions and roles. Therefore, fear and resistance to evaluation is as a result of employees not knowing the changes that this process will bring in the workplace; therefore, preferring maintenance of the status quo (Shell, 2002). Employee resistance to change is a widespread phenomenon in many workplaces since most of them do not want to be challenged by being asked to abandon routine and adopt new ways of doing things. Consequently, association of evaluation process to change in the way employees perform their duties is likely to en counter resistance (Austin, 2002). Evaluation has an important role in creating efficiency in organization functioning especially if it helps identify areas of waste, even in programs that seem to run successfully. Therefore, it is important that there is cooperation among everyone involved including staff and the management. When evaluation meets staff resistance, this indicates there is a problem that needs to be addressed through either the evaluation itself or prior to conducting staff evaluation. Therefore, the first area of concern when planning to undertake evaluation is to increase staff awareness of the process and possible actions based on results. Fear of evaluation is as a result of the unknown effect it will have on the staff especially as many of the employees wonder if they are going to lose their jobs, have increased workload or be held accountable for negative results. Consequently, evaluation should be done after employees have had adequate information access

Action Assignment#3 Assignment Example | Topics and Well Written Essays - 500 words - 1

Action #3 - Assignment Example They energize their goals, missions and visions to doing the best always. Leaders become more determined than ever in changing the society for the better. My name is Majed. I worked for eight years as a high school teacher of Arabic. The Ministry of Education provided me with a scholarship to study leadership at the University in the United States in order to gain the experience necessary to further my career. To be honest, the course has helped me a lot in growing as a leader. I learnt different values of leadership from the course which were lacking in my life. One of these values I learnt is the significance of responsiveness. I have applied responsiveness in different fields of leadership and the end result has been pleasing. Currently, I am the president of the American Youths for Change whereby I have enabled many young people abandon drug abuse. As a leader, I have motivated thousands of youths to pressurize their political leaders to become responsible. I have also staged numerous leadership seminars in both locally and internationally. In these seminars, I have been able to preach the importance of accountability to young leaders. This is due to economic stagnation which has affected many countries. Ideally, my dream is to see a corruption free world where leaders uphold the responsibility bestowed to them by their people. As a leader, I also dream to see a world where the rule of law is respected and a society where the opinion of every citizen counts. I also want to see a society where leaders have moral values and integrity. This will allow we the citizen have trust and hope in our government. As a leader, I want to leave a good legacy as someone who changed the society in a positive manner. I want to create a change in the society for the growth of my people. This is because I strongly believe that any standing society today has a possibility of dying. I want death to be alien to my society. My efforts to inspire the society have been rewarded.

Businesses and their impact in Spanish speaking countries Essay

Businesses and their impact in Spanish speaking countries - Essay Example With the increase in the demands for energy in recent years the government of Mexico has increased its budgeted capital, but due to its high tax burden the company has been forced to depend upon debts to finance the projects. PEMEX has been adversely affected by the increase in oil prices over the years and requires funding to stabilize its position in the market. The main oil field Cantarell has reached its peak capacity of production and heavy investments is desirable coupled with explorations for new area for oil production as the current capacity of 3.3 million barrels per day would deplete towards the end of this decade. Being heavily taxed, the President of Mexico has relaxed the tax by $2.4 billion to be paid by the company next year. Despite the reserves Mexico has started importing oil at the rate of 374,000 barrels per day in the recent past due to non availability of refining process for oil and related products. The tax break and provision of favorable environment for the oil companies to undertake oil exploration is one of the major steps which the newly appointed President has taken over the period of time. There have been quiet an opposed reaction to the initiative as private investments is deemed to be loss of control over PEMEX. As PEMEX has invested more in oil exploration rather than investing in refineries for a quarter of the century, Mexico now imports 20% of its current capacity of oil and 25% of the natural gas based products. The aim of the paper is to analyze and understand effect of PEMEX on the Mexican economy and society in general. The paper also analyzes the employment opportunity which private investments create and the favorable business environment for business growth. Mexico has the second largest oil reserve after Venezuela among the western countries and the country has been ranked among the top five oil producing nations for crude and refined oil production.

ENG - Essay Example A speech community can also develop from sharing lifestyles, hobbies and interests. People are often members of more than one speech community as they traverse from childhood to adulthood. Multiplexity is a degree of the types of relationships among members in a community. It is an important aspect of speech communities derivative from observing the ways in which persons are related. Each of these communities has their identity, culture, rules of membership that an individual has to adapt to. This essay seeks to identify a person’s journey across and between speech communities from childhood to adulthood. At childhood, a child is born to a speech community, the family. It is the basic speech community that the child has to adapt to their rules of membership, language and cultures. The family members share a language pattern that the child must adapt to. From the brothers, sisters and parents a child develops this language. The child grows up learning the language pattern the f amily members teaches them. The family dictates the speech norms, and as a child, the individual grows knowing that this is the language pattern they have to follow. The network strength in this community is based on family ties. The strength is strong since the family has a close-knit nature. The family has a low multiplexity level since it includes members with bloodily ties. After the family, the child starts attending school. At this stage, the child witnesses many speech communities. This depends on their characters and the activities they participate in school. In class, there exists a speech community between the teacher, the pupil and fellow pupils. In this community, the members use a formal language pattern with simple vocabularies. The members also have formal ties that relate to the curricular. This speech community has a specific language pattern that all the members have to adhere to. The density of the network strength is loose between the pupils and the teacher. Howe ver, between the students, they share a strong network density. Multiplexity level in this community is regular in the sense that the teacher may be one of the pupil’s parent and a relative to a fellow student. At school, the individual develops a friendship with peers either in class or during extracurricular activities. This friendship is based on sharing a common interest and hobbies. The friendship develops into a speech community where a group of friends shares the same language pattern. The social network in this community is dense since the members share ideas and interactions at a regular basis (Wardhaugh 120). Multiplexity is also common since, in this friendship circles, the members can be related. In this community, there exists a speech norm that each member enjoys and understands. Although the members differ in personal characteristics, they share the same hobbies and interest. For instance, it is common that members of this speech share the same genre of music. This community can be from adolescence to early teenhood. From teen hood to adulthood, the individual meets up a new speech community. This is usually in institutions of higher learning. The first speech community is in class depending on the course the person is studying. This speech community is different from junior and senior school. At this stage, the vocabulary is complex, and the language is very formal. There exists a mutual relationship between the lecture or professors and

Investigatin a ski jump Essay Example for Free

Investigatin a ski jump Essay Aim:To investigate how the starting position of a ski jumper affects the horizontal distance travelled in the jump. I will not take air resistance, friction and other various type of energy lost into account, however in practical I have to keep in mind that they do exist and cause variation in my results. Introduction Ski jumping is a sport event that involves a steep ramp and a landing zone, where the skier has to travel as far as possible after leaving the ramp horizontally. When the skier is in motion in the air and the range it reaches is what I am investigating. This motion is called the projectile motion and the displacement, velocity and acceleration of the projectile are all vector quantities. Each of these can be placed into vertical and horizontal components. In my experiment, I will create a similar model of the ski jump using a plastic curtain rail as the slope and model the skier as a particle, in this case, a ball bearing. Diagram This is a diagram of the basic equipment setup This investigation has much room for expansion on the original above setup. The accuracy can be improved using a combination of more sensitive measuring equipment and a more accurate measuring setup. B 1. The friction between the ball and the curtain rail, along with the air resistance are neglible, therefore, will not be accounted for in this experiment. 2. The ball bearing is taken as a point, as the motion of a rolling ball differs from anything else. 3. Gravity does not affect the horizontal velocity Prediction/Hypothesis I have based my prediction on the calculated formula R=V(4hH). Ball Bearing Object that models skier as a particle Meter Ruler Will be used to measure the range (x) travelled by the ball and the height (h) of the starting position. Measurements recorded in metres. Set square To make sure the height obtained is perpendicular to the table G-Clamp This will clamp the curtain rail to the table Table Where the slope will be placed on and clamped to Sand Tray This will be placed on the floor in the spot where the ball will land, leaving its mark. Method Variables Controlled Variables Constants Launching position Height of table. Acceleration due to gravity Time of flight Mass of ball Velocity 1. Test all equipment to make sure there are no problems and also test the sensitivity of the sand tray. 2. Set up appartus as show in diagram. 3. Check all apparatus are set up correctly and clamps are tightened securely 4. Using the meter ruler mark the 1st height at which the ball will be dropped from. In my case, I am recording 8 different heights ranged 0. 20m 0. 55m. Each within a 0. 05m interval. 5. Using the set square against the height, the exact position of the ball is determined. 6. The ball is manually held in place at the desired height and released, allowing the ball to roll down the ramp and off the edge of the table, landing on the sand. 7. The distance from the edge of the table to the mark made in the sand is measured and then recoded. 8. This is process is then repeated untill all results have been collected. Safety Precautions There are few minor risks in doing this experiment, which with careful setting up and appropriate behaviour, can be avoided. These are: When bending down to record measurements of the range, it is possible to bas your head coming up. Simply be aware of your surroundings. Having a sand pit on the floor can prove to be an obstruction to passers-by and can be a hazard of tripping over. I will make sure there are no obstructions by the landing zone when in practise. The ball bearing is heavy enough to cause injury to anyone if hit by it. Keeping distance should prevent this. Data interpretation Alongside doing the experiment I will plot a graph. This will allow for any correlations to be spotted early on and then further predictions to be made. It will also allow the investigattion of anomalies. Therefore drawing a graph alongside the experiment allows for greater scientific accuracy and better end results. Sensitivity The sensitivity of this experiment is concerned with by the accuracy of the equipment available. For example, a much more accurate measuring device can be used to distinguish to an accuracy of i 0. 1mm, but the ruler markings are only accurate themselves to i 1mm. Therefore, this creates a small error and show that to get the best out of the results, the most accurate equipment should be used in all situations. Accuracy. The accuracy of this experiment can be improved in a number of ways: When reading the ruler the eye must be at the same level as the object, otherwise an incorrect value will be seen. The range measuring ruler must measure from the point the ball leaves the ramp, which in this case is the edge of the table. This means that it must be accurately aligned under the table, this can be achieved using a plumb line. It is facing directly downwards, allowing the ruler to be placed directly under the point at which the ball leaves the ramp. There may be a small error in the position of the plumbline of about i 2mm. The sand in which the ball drops into may be uneven and the mark made when the ball strikes the sand may prove to be difficult to measure precisely. A travelling microscope could be used to measure the precise impact with the sand. But considering the level of accuracy used throughout the rest of the experiment, this would be an inefficient method. Results Height h/cm Height Distance x/cm Distance xi /cmi xmean H/m /cm2 1st 2nd 3rd Mean 1st 2nd 3rd Mean 1st 2nd 3rd. There were no anomalous results recorded in this experiment Error in distance x To calculate the positive error in x, the Xmean value is taken away from the Xmax value. To calculate the negative error in x, the Xmiin value is taken away from the Xmean value. Distance xi /cmi xmean xmax xmin Positive Error Negative Error Analysis From looking at the graphs, a positive correlation between the squared value of the range and the height the ball is dropped from can be seen, although points vary from the line of best fit. The results prove that the equation is correct and that the range of a ball does depend mostly on the height it is dropped from and the height the ball leaves the ramp. The formula (Ri =4Hh) states that an increase in the drop height, h, increases the range of the ball. The results have proved this and my prediction to be correct. However, the percentage at which the graphs agree to this equation is: H = 92cm 4H = 368cm (expected) Gradient of distancei graph = 192. 3 (experimental) Expected gradient = 368 192. 3 x 100% = 52. 3% agreement. 368 Conclusion In conclusion the experiment occurs the following way: The ball is released with high gravitational potential energy as it rolls down the slope, this energy is converted into kinetic energy, the higher the drop height, the longer the ball is travelling down the slope, so more energy can be transferred giving more kinetic energy and hence more speed when the ball leaves the ramp. From the results it is also seen that there are other factors that affect the range as the gradient was smaller than expected. The equation is correct, but the only part that could affect the results in this way was the assumption that all energy was transferred. The transfer is likely to be less efficient than assumed, 100% energy transfer from potential energy to kinetic energy is extremely unlikely. The energy can be lost in a variety of ways which are the limitations. Limitations Air resistance is an important limiting factor as it would have the most affect on the results. This was not counted for when doing the experiment and therefore has some affect on the results. As the ball moves through the air, the air itself is putting up a resistance against the ball, lowering its speed, and its distance travelled. Air resistance is dependant on the size of the object, as the larger the object the more air it has to push to the side. It also depends upon the speed at which the object is travelling, as an object travelling at faster speeds has to push aside more air in the same time. This effect can be used to explain the slight curvature at the top of the graph. This is because the ball is travelling at higher speeds (because it is being dropped from greater heights), with more air resistance acting upon it due to the higher speeds, causing it to cover less distance. Evaluation The trend of the graph 2 is a very clear with a positve correlation. There can be three different ranges of the line of best fit but I have only drawn the most obvious one. The 1st line of best fit can be drawn from the origin through the top ends of the error bars, whereas the 2nd can be drawn through the bottom ends of the error bars. However, due to the error bars being so small, it will be very difficult to show these 3 lines together. The accuracy and sensitivity of the apparatus leaves a minor error in the results giving a range of different values for that particular result. Ie. At a height of 5cm, the mean result was 31. 33cm. However this can actually be smaller or bigger than this value considering the errors in apparatus. The position of the plumbline to mark the the edge of the table will have an estimated i 2mm, having to join 2 meter rulers together will have an estimated i 1mm and judging the landing position of the ball will also have a i2mm effect on the results. In total the range of values for the results will be i 5mm. Therefor the range of values for 31. 33cm would be 30. 83cm 31. 83cm. Percentage error I will take the maximum result of the range and calculate the percentage error based on the uncertainty values. % error of range, x, 93. 33cm i 0. 5cm 0. 5cm i 93. 33cm x 100% = 0. 53% The values are vastly small and so are not worth considering. Improvements If this investigation were to be repeated, there are a few things I would like to change. Firstly, I would ensure to take more care that the above factors were fully compramised and minimised. Furthermore, I would take a much larger range of results to provide a more reliable end result, taking fairness of the experiment into account much more seriously. Finally, I would use a much more accurate range of apparatus to get the most accuracy in my results. For example, a specialised light gate can be set up at the end of the ramp to dictate the exact speed at which the ball leaves the ramp. This could then be considered with the mass to calculate the kinetic energy and gravitational potential energy and hence the total energy loss.

Pact Analysis And Prototype Design Information Technology Essay

Pact Analysis And Prototype Design Information Technology Essay The given report is based on the PACT analysis and prototype design for an interactive system. In respect to this, the paper introduces an initial non-functioning prototype interface for the interactive system for the selected design problem. The design problem selected for this interactive system is scenario 2. This problem is related with getting information about visiting places and eating, as in this city, Emily has faced problem in accessing expert knowledge and using Google maps mainly because of unavailability no local leaflets, paid advertising links, etc. As such, the design report reflects the PACT analysis and includes observations supporting this analysis. Further, it also includes secondary research as well as reflects feedback for initial design. All in all, an interactive system design for this design problem will be helpful in giving effective and relevant knowledge to the visitors about visiting and eating. PACT analysis is defined as a user requirement document that is used for a more detailed design brief. This analysis is a way of reflecting about people, activities, content and lastly technology (PACT Analysis). Each and every element of this analysis would be quite helpful in developing an effective interactive system that supports the users in accessing the local map. People reflect cognitive with physical characteristics, language, culture, etc. and other aspects. Activities indicate about actions and tasks including activities that support the new design. The third aspect is the context to use focuses on information about environment with acceptability of new design in relation to social, legal and ecological. Lastly, technology focuses on current technology and future technology to asses the problem in existing technology and type of technology, which will be used to solve out this technical issue. In relation to the given design problem, PACT analysis is conducted to make the information accessible to visitors. People: In this activity, people involved are senior team members, IT engineers having a good knowledge about hardware and software technical areas, graphic and interactive design experts and research team. There is a special requirement for IT experts and research team as both affect the designing of the interactive system. The special requirement for Information Technology (IT) expert is due to the reason that they have possessed a practical technical knowledge about software and hardware. Research team members have great domains in programming, visual design and cognitive psychology. The age range for each and every person involved is different. For the senior team members, the age range is in between 35-50 years. They can play a decisive role in building an interactive environment through solving behavioural issues. All in all, senior members can build up a good coordination among the members to effectively communicate ideas. Further, team members between 20 and 30 include those, who have innovative ideas and support in completing the tasks. IT engineer, graphic engineers and research team members are between the age range 30 and 45. In developing an interactive system, they can support in the designing of prototype and non-functioning prototype interface. In the current scenario, language is a great issue as visitors have faced problems in assessing the local knowledge due to unfamiliar language. Activities: To design an interactive system, the users have to perform activities that furnish long and in-depth information to the visitors. Additionally, they have to design a system in such an effective way that not only supports the visitors in searching local knowledge about the worth visiting and eating through providing database, but also works as a tool that freely intercommunicates knowledge to the visitors. Those activities must possess special characteristics like system should be easy to use, fast, and efficient. The new design will support in completing the activities like designing of interface, which is self teaching and also assists in gaining access to relevant and worthwhile information. Context to use: The features of the current context are that the presentation of local knowledge was not good in this city. Besides that, the system is not quite fast and effective with which it could be easy to assess the information. The environment would be stressful as the existing system was not responsive to the needs of the users. The new system needs to be used quickly through providing training in relation to the technical issues and ways to implement and maintain. In the designing of an interactive system, it is a must to focus on the needs of society, so that the society can be able to accept this system. For the new design, ecological and social acceptability affects the system at a great extent as both play a vital role in making the system user centric. Current technology: Technology is one of the determinative areas of concern as it directly affects the system design. Currently, notice and language are used as technology to respond to the needs of the users in a fast and efficient way without focusing on its ease to use. All in all, the current technology to serve local knowledge is mainly based on the systems functionality instead of visitors needs. This is a major problem in the current technology. Besides that, the current technology does not reflect the local attraction in the station and thus; visitors have faced a great problem in knowing places for visiting and eating without any guide. Future Technology: To solve this problem, the technology that could be used must focus on the users needs and also possess the characteristics of easy to use. Furthermore, books and signs are an effective technology that could be applied to cope with this problem as this will be helpful for the users in accessing knowledge about the local attractions of the particular city. Hardware helps the visitors that are looking for new attractions through informing and assisting in searching worth visiting places, whereas; software helps in making the database of local attractions in a city and also maintaining the speed and efficiency. This technology might provide opportunities like easy to access information within few minutes. Besides that, this technology might also give information about local attractions on mobile phone at low costs. For offering more functionality in the new system, new technology like books and signs might give an opportunity to attract number of visitors and also mee t visitors needs by assisting in keeping away the problems related to access expert knowledge. Observations supporting the PACT analysis Based on the above discussion about PACT analysis, it is inferred that this analysis is a quite effective tool with which it could be easy to assess information in a more detailed form. Besides that, it is also reflected that PACT analysis not only focuses on the specific requirements, but also indicates key point that are quite essential for evaluation. For instance: information about people helps in knowing people involved in the tasks. Furthermore, I have learned that for designing an interactive system, this analysis is highly effective as this helps in realizing the current situation and also reflects the areas for improvement, so that the new system can easily cope with the perceived problem. All in all, it is realized that PACT analysis is an effective tool to understand the users needs and amend the system according to the users acceptability. From the observations supporting the PACT analysis, it is learned that in this rapidly changing technological world, it is a must for an interactive system design that each and every aspect including people, activities, context and technology is properly assessed. With this, it would be easy to design a system that gives local knowledge of what is worth eating and visiting in a particular state. In addition to this, these observations will support in assessing the required changes that make the user interface effective in respect to functionality and users needs. Overall, PACT analysis is a tool for cooperative research, which acts as computer-aid-engineering for sharing and developing design model automatically. In the same concern, it is also observed that PACT analysis for an interactive system should also consider the communication as this meets out the issues like speed and bandwidth. In addition to this, observations will greatly assist the web designers in knowing about the users context, goals and tasks that directly lead in supporting the PACT analysis. With the observations, it could also be easy to assess whether the design prototype assists the goals and tasks in an effective way (Sharp, Rogers and Preece 2008). All the given observations in relation to the support of the PACT analysis were quite useful as they helped in getting relevant information about activities, context and technology. In response to the observations, the design visualization will add such a technology that gives a full and clear picture of area for improvement and also focuses on usability that makes visualisation easy to understand. Besides that, I will add more pictures, maps, signs, etc. as well as apply design strategies related to user interface. To make design visualisation effective, we will add all types of analyses including users, requirements and tasks. Thus, it is inferred that PACT analysis for an interactive system must be human centric, so that the required information can be easily extracted by the users. Secondary research Secondary research is one of the effective researches with which it could be easy to find out the solutions in context to the chosen scenario. This is because potential solutions linking with such issues are already reflected by other researchers. In helping the design of an interactive system, secondary research is quit useful as this research gives detailed information about the tourism and environment in context to the ecological, cultural, economic and language issues. Besides that, in design/visualization, secondary research will help in finding out the user requirements that are essential to design interactive system. In this context, Jones and Greene (2000) state that in the interactive system design, it is a must to foster creative perception, users and use context. The interesting idea that helps in developing the design is We view good system design as a three-legged stool. The legs are: 1) Understanding of technology, 2) Understanding of the users and the context in which the system will be used, and 3) A creative insight (Jones and Greene 2000). This means that a good system design is highly based on the proper knowledge and understanding of the users and technology as this is the only means to provide local attraction information to the visitors. It is also assessed from secondary research that for an effective design/visualisation to provide a guide to the tourists, it is a must to focus on the computing technologies with wireless infrastructure in order to provide the required information about the worth visiting sites. In support to this, Cheverst et.al state that The system combines mobile computing technologies with a wireless infrastructure to present the city visitors with the information tailored to both their personal and environmental contexts (Cheverst et.al). With this, it is analysed that for developing an interactive system, technology should be related with the users requirements. To make the design effective, another interesting idea proposed by Wober (2003) is that the designing of interactive system has to be supported with a marketing decision support system to assess the information about the prevailing users demand and current technology (Wober 2003). . Based on the above reflected potential solutions for the selected scenario, it is inferred that secondary research is good means as this research refers to the information that has been collected and properly analyzed by other researchers in context to the same issue. Feedback on the Design Visualisation In respect to the design visualisation, most of the users have reflected that this is a good system through which users can easily access the information of local destinations as this not only provides them with the database, but also helps them communicate in relation to various issues related to environment. This system would help in getting information about the worth visiting and eating sites, so that visitors can spend their time and money in an efficient way. As per their feedback, they would expect to see mobile networking with which they can access information on global maps on their mobiles at a lower cost. After looking at visualisation, most of them have the same question that whether this system is easy to use and will be helpful in fulfilling their needs. In response to the feedback, I would like to focus on all key dimensions such as technology, context and users. In addition to this, I would like to change the technology such as books, pens, notices, etc. to make the s ystem easy to use for the visitor. Besides that, I will implement mobile networking to change the design as most of the potential users highly require this technology in the interactive system.
