Performing for the World free essay sample
The stale smell of old tile floors and piano keys stung my nose. It was that old dusty smell that usually conjures up memories of Grandpaââ¬â¢s seasoned button down sweater, or the unkempt attic stored with keepsakes and memories from Christmas past. The large barred windows with paint chipping encased the beauty that is a Manhattan street from 10 stories high. Early morning beams of light cast upon the only things surrounding me; an over-enthusiastic conductor, music barely learned, and 500 other singers. It was our last rehearsal and our concert at Carnegie Hall was that night. I was on a trip with the Los Robles Childrenââ¬â¢s Choir; we were performing in a classical concert titled ââ¬Å"Mozartââ¬â¢s Solemn Vespers and Treble Chorus Worksâ⬠. Though I had the comfort and security of familiar faces from the choir, I felt as overwhelmed and lost as I ever have. The rehearsal continued as I artfully dodged potential paper cuts from music passing in and out of my hands a s we tried in earnest to get through the repertoire for the night. We will write a custom essay sample on Performing for the World or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The rehearsal ended with the sound of scuffling shoes down the stairs as I left the stale smell of the Civic Center room for the last time. Passing doors, my journey down the 10 flights of stairs was filled with the faint tinkling of ballet music and laughter. We had two hours of free time before we had to start getting ready for our concert. I walked down the street experiencing a sensory overload. The tall buildings made the streets dark; the odd smell from the blend of car exhaust and food carts teased my nostrils; the loud honks coming from the long lines of bright yellow taxis. The dissonant cords from Gershwinââ¬â¢s ââ¬Å"Rhapsody in Blueâ⬠played through my head as I scanned the melting pot that was ââ¬Å"The Big Appleâ⬠. I had reached my destination. I decided that with my free time I would visit Carnegie hall and look around inside too see what this place is all about. Opening the door I was invited with a friendly gust of air conditioning; a nice alternative to the humid summer air. The empty lobby and the faint whir of a vacuum contributed to the free and adventurous feeling I possessed when I wore my artistââ¬â¢s badge. This feeling took hold of me as I explored the hallways of Carnegie hall and came upon that familiar stale smell from hours before. I found the Carnegie hall visitors museum and decided that I would explore its contents before the big night ensued. Between old conductor batons and the original floor plans by Andrew Carnegie, I came upon ââ¬Å"The Listâ⬠. The list consists of everyone performance and performer who had the honor the grace the Stern Auditorium/Perelman stage. My eyes scanned the list to see that my name may soon grace the company of Judy Garland, Tchaikovsky, and Louis Armstrong. I soon became fascinated with that long people of paper in cased on the wall. It was humbling and inspiring looking at that list. My own accomplishments seemed irrelevant when compared to their own. Though at the same t ime I saw that my potential was nothing less than theirs at that point in my life and to the best of my capacity, I would leave my own mark on the world, as did they. This moment fostered the ambition and passion that has driven every activity that I now pursue. I walked hurriedly through the colorful streets of Manhattan to get back to 55th and 7th to get into my concert attire, and make my way towards the artistââ¬â¢s entrance. With binder in my upstage hand as made my way to the edge of the stage door, I realized that though anxiety and nervousness churned my stomach, I needed to get past that feeling and step out onto the stage. As my old right tattered character shoe stepped out onto the floor, making its debut to the audience that filled the seats, the left met up with it, ready to make its debut to the audience that would soon be the pallet that holds my experience, ambitions, and life.

Applications of Data Mining Techniques in Airline Industry Essays
Applications of Data Mining Techniques in Airline Industry Essays Applications of Data Mining Techniques in Airline Industry Essay Applications of Data Mining Techniques in Airline Industry Essay Purpose and Scope All around the universe, the air hose industry could be described in few words, which is intensely competitory and dynamic . The air hose industry generates one million millions of dollars every twelvemonth but still has a cumulative net income border of less than 1 % 1. Many Airlines are seeking to retrieve from deep debt. The grounds for these are multifold- fuel monetary values, high cyclicality and seasonality, ferocious competition, high fixed costs and many other issues related to security and riders safety. To guarantee for the best economic result, Airline companies are seeking with their most originative plus information. Datas used in concurrence with informations mining techniques allows comprehensive intelligent direction and decision-making system. Achieving these benefits in a timely and intelligent mode may assist in ensuing lower operating costs, better client service, market fight, increased net income border and stockholder value addition. This intent of this paper is to show the applications of informations mining techniques on multiple facets of air hose concern. For illustration, to foretell the figure of domestic and international air hose riders from a specific city/airport, to dynamically monetary value the tickets depending on seasonality and demand, to research the frequent circular database to fix for CRM execution, to makes the operational determinations about catering, forces, and gate traffic flow, to help the security bureaus for secure and safe flights for the rider specially after 9/11 incident. Predict the Number of Passenger by using Data Mining Technique Prediction is critical to any concern for planning and gross direction, particularly in the Airline industry, where a batch of planning is required to buy/lease new aircrafts, to engage crew members, to happen the new slots in busy airdromes and to acquire the blessings from many air power governments. In the instance of Air travel, batch of seasonality and cyclicality involved. Passengers are more likely to wing to some finishs based on the clip of the twelvemonth. Business travellers are likely to go weekdays than weekends. Early forenoon and eventide flights are desired by concern travellers who want to carry through a twenty-four hours s work at their finish and return the same twenty-four hours. To calculate the figure of rider, unreal nervous web ( ANN ) can be used. The intent of a nervous web is to larn to acknowledge forms in a given informations. Once the nervous web has been trained on samples of the given informations, it can do anticipations by observing similar forms in future informations. The growing factors which might act upon the air travel demand depend on several things. Mauro Calvano2 in his survey of conveyance Canada air power prognosis 2002-2016 considered 12 major socio-economic factors as follows: GDP Personal Disposable income Adult Populations US economic Mentality Airline Yield Fleet/route structure/Average Aircraft Size Passenger Load factors Labor cost and productiveness Fuel cost/Fuel efficiency Airline cost other than Fuel and Labor Passenger Traffic Allocation Assumptions New engineering Factors 1 to 5 are related demand side of the prognosis Factors 6 to 10 are related to operations and supply side Factors 10 and 11 represent the structural alterations This historical information is called the appraisal set. A fraction of the overall available information is reserved for formalizing the truth of the developed prognosis theoretical account. This reserved information set is called the prediction set because no information contained in it is used in any signifier during the development of the prognosis theoretical account. The information in the prediction set are used for proving the true extrapolative belongingss of the developed prognosis theoretical account. The appraisal set is farther divided into a preparation set and a testing set. Information in the preparation set is used straight for the finding of the prognosis theoretical account, whereas information in the testing set is used indirectly for the same intent. Figure1: Forecasting Process Model For a given ANN architecture and a preparation set, the basic mechanism behind most supervised acquisition regulations is the updating of the weights and the prejudice footings, until the mean squared mistake ( MSE ) between the end product predicted by the web and the desired end product ( the mark ) is less than a pre-specified tolerance. Nervous webs are can be represented as beds of functional nodes. The most general signifier of a nervous web theoretical account used in prediction can be written as: Y = F [ H1 ( x ) , H2 ( x ) , aÃâ à ¦ . , Hn ( x ) ] + U Where, Y is a dependant or end product variable, Ten is a set of input/ influencing variables, F A ; H s are web maps, and U is a theoretical account mistake. This input bed is connected to a concealed bed. Hs are the concealed bed nodes and represents different nonlinear maps. Each node in a bed receives its input from the predating bed through nexus which has weights assigned, which get adjusted utilizing an appropriate acquisition algorithm and the information contained in the preparation set. Figure2: ANN Architecture Abdullah Omer BaFail3 did the survey to calculate the figure of air hose rider in Saudi Arabia. He selected the most influencing factors to calculate the figure of domestic riders in the different metropoliss of Saudi Arabia. For Dhahran he selected factors like: Oil gross domestic merchandise for last 6 old ages, private non-oil gross domestic merchandise, Import of goods and services for last 10 old ages, and population size for last 2 old ages. The domestic and international existent and forecasted figure of riders for the metropolis of Dhahran for the old ages 1993 through 1998 is shown below. Prognosiss underestimated the existent travel. The Mean Absolute Percentage Error ( MAPE ) for domestic travel is about 10 % , while for international travel is about 3 % . Figure3: Forecasting consequences from Abdullah Omer BaFail3 The take away from the Abdullah Omer BaFail3 for me is that the efficient prediction theoretical account can be invented utilizing ANN if we utilizing the right influencing indexs. In this survey some indexs which influence are oil gross domestic merchandise and per capita income in the domestic and international sectors. In position of the fluctuating nature of the rider use of air hose services in Saudi Arabia, certain suggestions were made. Most of these recommendations were in order to better the flexibleness of the system to the fluctuations in demand and supply. Hub and spike theoretical account was besides suggested as solutions in certain sectors to increase the flexibleness in seting their capacity allotments across markets as new information about demand conditions become available. Application of Data Mining technique to foretell the Airline Passengers No-show Ratess Airlines overbook the flights based on the outlook that some per centum of engaged riders will non demo for each flight. Accurate prognosiss of the expected figure of no-shows for each flight can increase air hose gross by cut downing the figure of perishable seats ( empty seats that might otherwise hold been sold ) and the figure of nonvoluntary denied embarkation s at the going gate. Typically, the simplest manner is to travel for mean no-show rates of historically similar flights, without the usage of passenger-specific information. Lawernce, Hong, Cherrier4 in their research paper predicted the no-show rates utilizing specific information on the single riders booked on each flight. The Airlines offer multiple menus in different booking category. The figure of seats allocated to each booking category is driven by demand for each category, such that gross is maximized. For illustration, few seats can be kept on clasp for the last-minute travellers with high menus and figure of seats sold in lower-fare categories earlier in the engagement procedure. Footings and conditions of cancellation and no-show besides vary in each category. The no-shows consequences in lost gross if the flight departs with empty seats that might otherwise hold been sold. Near accurate prognosiss of the expected figure of no-shows for each flight are really much desirable because the under-prediction of no-shows leads to loss of possible gross from empty seats, while over-prediction can bring forth a important cost punishment associated with denied embarkations at the going gate and besides make client dissatisfaction. In the simplest theoretical account, the overbooking bound is taken as the capacity plus the estimated figure of no-shows. Engagements are offered up to this degree. No-shows Numberss are predicted utilizing time-series methods such as taking the seasonally leaden traveling norm of no-shows for old cases of the same flight. Figure4: No-show tendency over yearss to departure Beginning: Lawernce, Hong, Cherrier4 The simple theoretical account does non take history of specific features of the riders. Lawernce, Hong, Cherrier4 in his survey used categorization method, likewise Kalka and Weber5 at Lufthansa used initiation trees to calculate passenger-level no-show chances, and compared their truth with conventional, historical-based methods. I tried to sum up Lawernce, Hong, Cherrier4 attack and consequences briefly below. Whenever a ticket is booked the Passenger Name Records ( PNRs ) is generated and all the rider information is recorded. The PNR information includes, for each rider, particulars of all flights in the path, the engagement category, and rider specific information such as frequent-flier rank, fining position, and the agent or channel through which the engagement originated. Each PNR is besides specified whether the rider was a no-show for the specified flight. In the simplest theoretical account the average no-show rate over a group of similar historical flights is computed. The mean in bend used to foretell the figure of no-shows over all engagement categories. The passenger-level theoretical account given by can be implemented utilizing any categorization method capable of bring forthing the normalized chances. The PNR records are partitioned into sections, and separate prognostic theoretical accounts are developed for each section. In the passenger-level mold we characterize each utilizing the PNR inside informations. Let Xi ; one = 1aÃâ à ¦aÃâ à ¦aÃâ à ¦aÃâ à ¦..I denote I characteristics associated with each rider. Uniting all characteristics yields the characteristic vector Ten = [ X1aÃâ à ¦aÃâ à ¦aÃâ à ¦Xi ] Each rider, n = 1aÃâ à ¦aÃâ à ¦aÃâ à ¦aÃâ à ¦aÃâ à ¦.N, booked on flight m is represented by the vector of characteristic values xmn = [ xmn, 1aÃâ à ¦aÃâ à ¦aÃâ à ¦aÃâ à ¦aÃâ à ¦aÃâ à ¦ xmn, iaÃâ à ¦aÃâ à ¦aÃâ à ¦aÃâ à ¦aÃâ à ¦.. xmn, I ] We know the predicted no-show rate from the historical theoretical account ; it is assumed the rider inherits the no-show rate. The rider degree prognostic theoretical account is so stated as follows: given a set of category labels cmn a set of characteristic vectors xmn and a cabin degree historical anticipation Aà µmhist predict the end product category of rider N on flight m: P ( C = cmn | Aà µmhist, X= xmn ) We are specifically interested in the no-show chance, cmn = NS, and compose this chance in the simplified signifier P ( NS | Aà µmhist, xmn ) The figure of no-shows in the cabin is estimated as a?ââ¬Ë P ( NS | Aà µmhist, xmn ) The summing of chances for each rider in the cabin, gives no-show rate for the cabin. An correspondent attack can besides be used to foretell no-show rates at the fare-class degree. Lawernce, Hong, Cherrier4 comparison consequences computed utilizing the historical, passenger-level, and cabin-level theoretical accounts. The theoretical accounts were built utilizing about 880,000 PNRs booked on 10,931 flights, and evaluated against 374,900 PNRs booked on 4088 flights. The figure shows a conventional lift curve computed utilizing the three different executions of the passenger-level theoretical account. Figure 5: Addition Charts Beginning: Lawernce, Hong, Cherrier4 Each point on the lift curve shows the fraction of existent no-shows observed in a sample of PNRs selected in order of diminishing no-show chance. The diagonal line shows the baseline instance in which it is assumed that the chances are drawn from a random distribution. The three executions of the passenger-level theoretical account place about 52 % of the existent no-shows in the first 10 % of the sorted PNRs. This is one of the manner the Airlines can integrate informations excavation theoretical accounts integrating specific information on single riders can bring forth more accurate anticipations of no-show rates than conventional, historical based, statistical methods. Application of Data Mining technique to Strategies Customer Relationship Management In the current clip most of the industries utilizing frequence selling plans as a scheme for retaining client trueness in the signifier of points, stat mis, dollars, beans and so on. Airlines are a large fan of this Kingfishers Kingmiles, Jet Airways Jet Privilege, American Airlines AAdvantage, Japan Airlines Mileage Bank, KrisFlyer Miles etc. they all seemed to hold carved their ain individualities. Frequent Flyer Program presents an priceless chance to garner client information. It helps to understand the behavioral forms, unveil new chances, client acquisition and keeping chances. This helps Airlines to place the most valuable and the appropriate schemes to utilize in developing one-to-one relationships with these clients. The aim of informations mining application over the frequent circular client informations could be many, but ideally it is as follows: Customer cleavage Customer satisfaction analysis Customer activity analysis Customer keeping analysis Some of the illustrations in each class are: Classify the clients into groups based on sectors most often flown, category, period of twelvemonth, clip of the twenty-four hours, intent of the trip. Which types of clients are more valuable? Do most valuable clients receive the value for money? What are the properties and features of the most valuable client sections? What type of run is appropriate for best usage of resources? What are the chances to up-selling and cross-selling, for illustration hotel engagement, ascent to following category, recognition card, etc. Design bundles or grouping of services Customer acquisition. Yoon6 designed a database cognition find procedure dwelling of five stairss: choosing application sphere, mark informations choice, pre-processing informations, pull outing cognition, and reading and rating. This survey refers to the Yoon procedure to cover with three excavation stages, including the pre-process, data-mining, and reading stages for air hoses, as illustrated in figure below. Figure 6: database cognition find procedure Beginning: Yoon6 Some straightforward solution can be implemented that can besides be scaled-up in future like K-means, Kohonen self-organizing webs and categorization trees. In the instance of K-means algorithm, it is applied on client informations, delegating each to the closest bing bunch centre. The K- means theoretical account is run with different bunch figure until K-means bunchs are good separated. In the instance of categorization trees ( C5.0 ) , we derive a simple regulation set to unambiguously sort the complete database. Again, we have to bring forth the properties, ensuing from the sequence of flight sections. The truth of the prognosis for each section is provided by equilibrating the preparation set harmonizing to every bit sized bunchs. We regulate the figure of subsequent regulations, while finding a minimum Numberss of records given within each subgroup. Maalouf and Mansour7 did the survey based on 1,322,409 client activities minutess and 79,782 riders for a period of 6 old ages. They prepared Data based on Z-Score Normalization and ran the multiple questions and transformed the informations to make the bunch input records. They used K-means and O-Cluster algorithms. The consequence generated by constellating provides client cleavage with regard to of import dimensions of clients demands and value. The tabular array below is the consequence is a sum-up of the profile produced by k-means constellating that includes: gross milage, figure of services used, and client rank period. Figure 7: Clustering consequence on Airline Customer Data Beginning: Maalouf and Mansour7 The consequences generated by k-means constellating are used as a footing for the association regulations algorithm. Two different scenarios have been applied. The first scenario is based on Financial , Flight , and Hotel activities with 1,896 records. The 2nd scenario is based on the flight activities particularly the sectors, with 1,867 records. Figure 8: Association regulations for best client activities Beginning: Maalouf and Mansour7 Some of the take manner from Meatloaf and Mansour7 survey. Clustering utilizing k-means algorithm generated 9 different bunchs with specific profile for each one. From the bunch analysis it can be found which are the best client bunchs ( higher milage per rider ) than other bunchs. Necessitate a keeping scheme for these bunchs. Cross Selling schemes can be formulated between the bunchs ( for illustration between: 15 and 11 ; 13 and 17 because they are close in services value. The bunch analysis provides an chance for the air hose to bring forth more gross from a client. For illustration, the air hose could use an up-selling scheme by selling a higher menu place depending on the bunchs. From the bunch analysis Airline may follow an enhanced scheme for clients in bunchs in order to increase services usage and gross milage per rider. Plan for marketing run or particular offers by analysis through association regulations, for illustration, the clients utilizing the Flight and Financial services neer use the Hotel Services and the clients utilizing the Flight and Hotel services neer use the Financial Services. By analysing the services used in different bunchs, Airline can qualify services integrating. It enables the air hose to function a client the manner the client wants to be served. Application of Data Mining Application technique to understand the Impacts of Severe Weather Severe conditions has major impacts on the air traffic and flight holds. Appropriate proactive schemes for different severe-weather yearss may ensue in betterment of holds and cancellations. Therefore, understanding en-route conditions impacts on flight public presentation is an of import measure for bettering flight public presentation. Zohreh and Jianping8 in their survey proposed a model for informations mining attack to analysis of conditions impacts on Airspace system public presentation. This attack consists of three stages: informations readying, characteristic extraction, and informations excavation. The information readying stage includes the usual procedure of choice of informations beginnings, informations integrating, and informations data format. Figure 9: Model proposed by Zohreh and Jianping8 He used three informations beginnings: Airline Service Quality Performance ( ASQP ) , Enhanced Traffic Management System ( ETMS ) , and National Convective Weather Forecast ( NCWF ) supplied by National Center for Atmospheric Research. He used NCWF informations from April through September 2000 to stand for the terrible conditions season. These data-sets included the scheduled and existent going and arrival times of each flight of 10 coverage air hoses, tail figure, wheels off/on times, cab times, cancellation and recreation information, planned going and arrival times, existent going and arrival times, planned flight paths, existent flight paths, and cancellations, flight frequences between two airdromes, intended flight paths between two airdromes, flight holds, flight cancellations, and flight recreations. The image cleavage stage resulted in a set of severe-weather parts. Then for each of these parts, a set of conditions characteristics and a set of air traffic characteristics are extracted. A twenty-four hours is described by a set of severe-weather parts, each holding a figure of conditions and traffic characteristics. As a consequence of this survey it was found that there is strong correlativity of out of use flights, # of bad conditions parts, bad conditions airdromes, blocked distance, bad conditions longitude, by base on balls distance, bad conditions latitude, # of bad conditions pels with flight public presentation. Similarly the bunch algorithms ( like K-means ) can be applied. The outlook is that the same bunchs have similar conditions impacts on flight public presentation. Zohreh and Jianping8 generated bunchs for the full air space It was found that a bunch with worse conditions about ever had bad public presentation. The bunchs with big per centum of out of use flights, beltway distance, and blocked distance had a worse public presentation. These consequences were promising and showed that yearss in a bunch have similar conditions impacts on flight public presentation Other informations excavation attack which can be applied is Classifications. Application of Classification can assist us detect the patterns/rules that have important impact on the flight public presentation. Discovered regulations may be used to foretell if a twenty-four hours is a good or a bad public presentation twenty-four hours based on its conditions. For illustration Rule for Good: if % BlockedFlights lt ; = xxx and BypassDistance lt ; = yyy so Good ( n, prob ) There can be different ways where we can use informations mining attack to analysis of upwind impact on air hose public presentation. It seems to be that consequences obtained from constellating and categorizations were really meaningful for air hose and riders to be after in front. Application of Data Mining techniques to guarantee safety and security of Airlines rider The reaction of the terrorist onslaught on 26/9 and 11/9 end point in addition Security at airdromes: It ends up leting merely ticketed riders past the security Gatess, screen carry-on baggage more carefully for possible arms. The inquiry is whether these stairss could hold avoided the onslaughts, the people involved in the onslaught had legitimate tickets, and transporting box cutters and razor blades ( like in any other normal individual would make ) . The uncommon was the combination of their features, like none were U.S. citizens, all had lived in the U.S. for some period of clip, all had connexions to a peculiar foreign state, all had purchased one-way tickets at the gate with hard currency. With the sum of informations available about the rider during fining, the can be reviewed to qualify relevant available rider information. Give a rider s name, reference, and a contact phone figure, assorted informations bases ( public or private ) can place the societal security figure ( SSN ) , from which much information will be readily available ( recognition history, constabulary record, instruction, employment, age, gender, etc. ) . Since there is big figure of features available on both single riders, it will be of import to placing signals within the natural variableness or noise . If predicted incorrectly, this may take to either falsely confining an guiltless rider or neglecting to confine a plane that carries a terrorist. The air hoses already collect much informations on assorted flights. When the informations come in the signifier of multiple features on a individual point, exploratory tools for multivariate informations can be applied, such as categorization, arrested development trees, multivariate adaptative arrested development splines/trees. The security of the air transit can be improved well through modern, intelligent usage of pattern acknowledgment techniques applied to big linked databases. Similarly Data excavation techniques can be used for the Safety of the rider. An air safety office plays a cardinal function in guaranting that an air power organisation operates in a safe mode. Currently, Aviation Safety offices collect and analyze the incident studies by a combination of manual and machine-controlled methods.. Data analysis is done by safety officers who are really familiar with the sphere. With Data mining one can happen interesting and utile information hidden in the informations that might non be found by merely tracking and questioning the information, or even by utilizing more sophisticated question and coverage tools. In a survey done by Zohreh Nazeri, Eric Bloedorn, Paul Ostwald10 it was found that happening associations and distribution forms in the informations, conveying of import interior. The other determination is Associating the incident studies to other beginnings of safety related informations, such as aircraft care and conditions informations, could assist happening better causal relationships. SumMRry Business Intelligence through efficient and appropriate Data excavation application can be really utile in the Airline industry. The Appropriate action programs from the information excavation analysis can ensue in improved client service, aid bring forthing considerable fiscal lift and set the hereafter scheme.

Are GMOs helpful or harmful Essay Example | Topics and Well Written Essays - 750 words
Are GMOs helpful or harmful - Essay Example This has resulted in many scientists coming up with the ways of increasing productivity of the already existing land. In fact, some ways of growing GMO include irrigation of arid areas and use of fertilizers. On top of that, there have been efforts to reclaim land from the seas and oceans. For example, dykes constructed in Netherlands for creation of more land necessary for horticulture farming. Despite the above suggestions, there has been starvation in some countries when they are strike by drought like in Zimbabwe and Zambia. Therefore, scientists have come up with the idea of growing crops that are genetically modified. The idea has been met with a lot of criticism despite being seen as the only viable solution to hunger elimination. GMOs can be either harmful or helpful according to various arguments and perspectives. They are helpful because of the following; there has been lack of enough traditional seed to be planted. This suggests that it will result to food shortage if the genetic foods are banned. The food shortage consequently results to increase of the cost of food which is already high. The high prices on the food are because of increase in demand and unfavorable weather changes. However, with genetic food, more food will be produced and the cost of food will instead go down. For instance, in US, the Agricultural Department has rein-stored the modified weed killer resistant sugar-beet because more than half of sugar produced in US has been genetically modified. There are also modified cotton and soya beans (Kilman and Tomson 10). Another benefit of genetic foods is that the crops are resistant to pests and viruses due to use of technology. Hence, food prices go down due to the continuous practice of large scale farming will be easy. For example in Europe, they have adopted genetic modification to reduce the high demand for wheat and avoid future shortages which can result to starvation (Pendrous 24). There has been

A review Article Example | Topics and Well Written Essays - 1500 words
A review - Article Example She sheds light on the uneasy relationship of Computer Assisted Language Learning (CALL) and Second Language Acquisition (SAL) processes and gives an account of the present state of the art and points towards the new and challenging directions of SAL. Chapelle writes ââ¬Å"The point of departure for this article is the dissimilarity between the theoretical landscape within view of language teaching professionals in 1991 and that of todayâ⬠. (p.741)The pragmatic goal of computer-assisted language learning (CALL) developers and researchers to create and evaluate learning opportunities and a variety of theoretical approaches to second language acquisition (SLA) which have developed, are alternative beats of the same heart. The multiple theoretical perspectives grouped into four general approaches support this perspective as elucidated by Chapelle who writes: ââ¬Å"Cognitive linguistic (Universal Grammar, autonomous induction theory, and the concept-oriented approach); psycholinguistic (processibility theory, input processing theory, interactionist theory); human learning (associative-cognitive CREED, skill acquisition theory); and language in social context (sociocultural, language socialization, conversation analysis, systemic-functional, complexity theory)â⬠( p.741). Technological advances and internet revolution and the resultant changes have necessitated modifications of communicative competitive theory and this has proffered a direct challenge to Second Language Acquisition (SLA). This theory lays much emphasis on natural talents and process through which a student undergoes, than in instructed SLA. As per this theory, the learning process goes on without the student being actively conscious of it. The process is just like the elementary command on the mother-tongue exercised by a child even before going to school and that process of self-education goes within the perimeters of the household and immediate

Oxfam coat Essay Example for Free
Oxfam coat Essay In the Oxfam coat, Anna Adams is able to elaborate with a dry irony the symbolism of a coat and all that it contains. In the unison of this frock, there is the hopefulness of expectation and the knowledge that very much it is a conceit towards a better life that is somehow illusory and never quite there. There is something so sturdy about this coat, but in its impoverished outline, there are thematic qualities which ring of an inevitable notion that more than one thing can be seen from it. In much of society and in judgement, clothes are one indicator of socioeconomic class and forms a classification of people, their preferences, and their prejudices, even. In the poem, the speaker seems to be in some ways, using this poem for knowledge. ââ¬Å"I do not wear this coat to be admired,/not even to be seen; it is for seeing from. â⬠Sometimes a person might wear a certain outfit to indicate a certain station in life. Just like during the Mardi Gras in Venice rich men sometimes dressed as beggars in tattered rags just to expose themselves to the expectations that are given to the poor. Also, in the Mark Twin story, ââ¬Å"The Prince and the Pauperâ⬠all it takes for the prince and the pauper to switch places is a trading of clothes. That something so simple as donning a new frock, that something like this can give people new vantages is a commentary on a society that judges at times with the blink of an eye. In some ways, it seems like the speaker is trying to analogize her life to that of a farmers wife. Based on her sophisticated dialect and the advanced qualities of her grammar. It seems unlikely that she has been or was a farmers wife, it seems like even when wearing a shabby Oxfam coat. The analogy towards sacrifice and a sort of poverty, that is nevertheless good, a different lifestyle, history, and experience. The speaker, like the Prince in The Prince and the Pauperâ⬠cannot abandon the learning he has received. For when he draws the crown seal to prove his identity, he is proving himself despite the dirt on his face and the shabby misery of his appearance. When the speaker voices, ââ¬Å"I am a walking look-out post, attired. â⬠The word attired is by a dictionary denotation merely saying that she was wearing something which was not all too flattering. Like the paint on a walking look-out post is rarely glossy or shiny, but rather dull and worn, tired in a way in appearance. An apparatus of sorts in its rudimentary appeal and dignity regardless of the season, the hour or the time. Yet despite the adaptation of a literal denotation of attired, there is furthermore the connotation of being tired. The farmers wife is thought of to work tirelessly, without a murmur, watching out for all around her, a sturdy sediment against instability and working mightily to overcome the elements. While its certainly a bit insulting that the speaker seems to objectify the farmers wife. Comparing the frock to the deaf, dead-leaf look of camouflage and inconspicuous sight, there is evidently some derision in the admiration as well. ââ¬Å"I am a walking look-out post, attired/in mist and dead-leaf coloured camouflage-a watchers hide, a property/advisible as poverty, as inconspicuous as middle-age. /it must have needed thirty years at least,/to reach this natural state and yet remain an artefact/that keeps me warm. To ditch it would be a waste. â⬠The derision seems to be there, as theres the comparison of the worn coat to a natural state. It is not clear why thirty years of hard work and poverty ages a coat, that is symbolic of a toil-friendly farmers wife, to be a container for the poverty and overwork that is typically referred to rural scenes and states. In some ways, the naturalization of the farmers wife coincides with the objectification of the supposed farmers wife who is symbolized by the worn Oxfam coat. There is an organic, yet maturing or dead quality, of a kind of soulless duty as personified by the utility yet absence of personality of the illusion of a farmers wife vis a vis the Oxfam coat. ââ¬Å"It cost me twenty pence. Good Harris cloth,/springy as heathers turf:/it has outworn the striding farmers wife/its cut suggests. Her scarecrow bones are earth. â⬠The organic thematization is still present, as the omnipresent aspect of death and decay ares still there. That even this sturdy coat may have taxed the farmers wife who wore herself to the bones and is part of the earth as much as dead leaves melt into the dirt. The personification of this coat, in some ways serves to eclipse the deadness or gone quality of the farmers wife with its being as worn by someone else. Who cannot help thinking into the life and times of a farmers wife. However insulting or even mistaken it may be, undoubtably farmers wives lead hard lives but in some ways, we all do. That in fighting against organic matter, the endurability of good, sturdy cloth can preserve some aspects of feeling invulnerable but that people in the end, all melt into the earth. Perhaps the speaker is more than a bit sympathetically derogatory of the life and times of the farmers wife because she too, is stricken by a fear of death and being worn out. Possibly in moving the quality of being worn and an ââ¬Å"artefact,â⬠an outmoded cultural icon, there is an attempt to deal with the has been quality that is pervasive of many fields including that of poetry. Where a person may be a morning star one day, brilliant and admired, then thrown into the rubble the next day, exiled and socially excommunicated. In lending so much emotion, thought, and headlining grief to this Oxfam coat is perhaps a way to reconcile with the recyclability of not only leaves but people. That in a society which treasures the use of people for its own means, its in some senses hard for people to really express themselves. That in especially tough situations of environments there are so few choices to choose from and so few worlds to inhabit and wear. ââ¬Å"It has outworn its power to startle birds/and has become a rough/looking-glass fibre stuff/chameleon, reflecting wintry woods. /that matted sheep-potential bale of wool/on knitting-needle legs-/sees me as sheep. Those twigs/sense me as bark-skinned tree if I stand still. â⬠The use of people is at times so much changing as people are expected to objectify themselves in so many ways, that apart from a degeneration into the dirt caused by organic decay. People are expected to transform themselves from the natural to the created, just as wool is transformed by the knitting-needle into something like a sweater. The wool as fetched from the backs of sheep, sheared for warmth, is transformed in the shop by the needle to turn itself into something more that people can simply use. When the speaker wears this coat and feels that she may be more degraded and not regarded so well, looked upon as sheep. A vulnerable yet strong person who is fleeced or can be fleeced. That despite the almost insulting attitude towards the hardship of the farmers wife. The distancing yet empathy that is regenerated in this poem. That the speaker wears the pain and suffering of the farmers wife like a costume. That there is an idiosyncratic individuality which borrows from the uniformity of a farmers wife to converge into some medium point. There is still, an unavailability of true emotion or authentic sympathy, as to ââ¬Å"travel incognitoâ⬠as to ââ¬Å"register on no mans retina. â⬠Is a way of distancing oneself from a role, or even an affectation while still borrowing so much from it. Ultimately the farmers wife is much removed and only imagined, like some pastoral painting. In conclusion, we can only receive her secondhand, like the worn Oxfam coat, there but not there at the same time because life is never given to it in full.

Billy Bathegate by EL Doctorow Essay -- Essays Papers
Billy Bathegate by EL Doctorow Billy Bathgate is an important American novel in itââ¬â¢s portrayal of one young manââ¬â¢s evolution from boyhood to maturity. The novel is about a fifteen year old boy that gets taken under the wing of Dutch Schultz, a 1930ââ¬â¢s gangster trying to keep a hold of his diminishing empire. As the novel unfolds, so does the rising maturity of the tough young man introduced to us as Billy Bathgate. Billy finds himself in situations that most of us never see in our whole life. In difference to the reactions that most people would have in these situations, Billy learns from them in order to better his role in the crime family. It is for these reasons that the young fifteen year old boy quickly develops into a man. Author Overview The novel was written in 1989 by a contemporaneous author named E. L. Doctorow. Doctorow was born in 1931 and fantasized about the 1930ââ¬â¢s crime life as a child. He is an American novelist, short story writer, editor, essayist, as well as a dramatist. His works include Big as Life, The Book of Daniel, Ragtime, Loon Lake, Worldââ¬â¢s Fair, , Lives of the Poets: Six Stories and a Novella, a play entitled Drinks Before Dinner and of course his most recent work Billy Bathgate. Billy Bathgate is Doctorowââ¬â¢s most famous piece of literature. In fact, the book grasped so much attention that it was later made into a movie with an all star cast including Bruce Willis, Dustin Hoffman and Nicole Kidman. Although the film left out a lot of detail, as so many movies based on novels tend to do, it was interesting to see the elaborate detail given to the clothing, attitude, and backdrop that so accurately reflect the inner city Bronx in the 1930ââ¬â¢s. Doctorowââ¬â¢s ex plicit, graphic detail show his almost fascination with crime and murder. He almost glamorizes the life of crime in Billy Bathgate. Critical Analisys Although Billy Bathgate was written quite recently, there is an influx of critical opinion reflecting the admiration of Doctorowââ¬â¢s artistry in literature. "Critics marveled at Doctorowââ¬â¢s vivid description of New York City in the 1930ââ¬â¢s and of the horrific murders committed by Dutch and his gang."(CLC volume 65 Author Overview) "Billy Bathgate is intended as pure myth, a sort of Robin Hood for grown-ups. Other novels may be more psychologically subtle or emotionally resonant. But few of those ... ...sting novel that I have ever had the pleasure of reading. It is one of those novels that you just can not put down if you try. Billy Bathgate is a vital American novel in itââ¬â¢s portrayal of a boyââ¬â¢s journey to become a man.

Enzymes are important for food digestion Essay
Enzymes are protein molecules produced y the living cells as ââ¬Å"instructedâ⬠by genes on the chromosomes. Enzymes referred to as biological catalyst ââ¬â biological molecules that catalyze metabolic reactions. A catalyst is defined as an agent that speeds up a chemical reaction without being consumed in the process (Burton, G. R. W. , 2004). Enzymes are important in digestion of food in our body because they act as the vehicle in the chemical reactions of breaking up the food elements. If the enzymes are not present in the digestion of the food, the energy of the chain reaction will face different problems such as acidity, diarrhea, bloating and burning sensation and it also helps strengthening the immunity of the body. There are different types of enzymes. These are metabolic enzyme, digestive enzyme and food enzyme. Metabolic enzymes are responsible for the destruction and removal of toxins in the body. Digestive enzymes are responsible for the digestion of food, absorption and the delivery of nutrients throughout the body and food enzymes enables the body to digest the food by breaking down the various nutrients and this enzyme are responsible for maintaining the optimal health. I will focus more on the digestive enzyme because it has an important role in the digestion and distribution of nutrients in the body. This enzyme can also help on the recovery of many diseases such as Irritable Bowel Syndrome (IBS) and Crohns disease. There are 3 important enzymes for the digestion and these are protease which digests protein; amylase which digests carbohydrates and lipase which digests fat. The two groups of digestive enzyme are intrinsic and extrinsic digestive enzyme. The intrinsic digestive enzyme is naturally produced inside the body and secreted from several organs to break down foods. Salivary gland is the most common enzyme produced by the mouth and the gastric gland produced by the stomach. If you experienced burning sensation and bloating and always in need of antacids after eating a certain types of food, the most common reason for this is due to eating of highly processed or over cooked food. This is commonly called indigestible foods. This type of food has naturally occurring enzymes but some healthy nutrients have been removed. The foods that has no enzymes and indigestible is bad for your health. The enzymes will work with the help of other necessary nutrients called the co-factors such as vitamins, minerals and essential fatty acids. In the absence of the co-factors of the enzymes, enzymes will have no activity. In some studies, it shows that the burning sensation you feel after eating a heavy meal like steaks, chickens, hamburgers and the like is because the digestive system demands more enzymes to digest them but if you eat raw type of food like fresh fruits and vegetables you will not feel any burning sensation because fresh vegetables and raw already contains lots of enzymes that digestion can be easier. We can eat any kind of foods that are rich in fat and sugars and our body will try to break it down by means of enzyme (Garcia, B. , n. d). To prevent the burning sensation, acidity and excessive gas, we should eat a natural raw kind of food and light cooked foods. Over cooked foods and processed destroys the enzymes that we need. Reheating the left over food at 47 degrees Celsius also destroys the enzyme that we need for digestion. The best way to have a good digestion is we should eat fresh fruit, steamed vegetables and dairy products to get plenty of digestive enzymes for easy digestion and absorption of nutrients in our body. If we are about to eat roasted meat, try to add some raw vegetables because it contains vegetable enzyme that will help for easy digestion. Eating this kind of food is very economical and it helps with digestion illnesses. Enzymes are important in our life. Without enzymes we easily get sick or acquire diseases. Lacks on enzyme in our body makes our blood dirty and dirty blood are the basis of acquiring diseases. One specific function of enzymes is to reduce and lighten the inflammation such as arthritis. We should always remember that the healthier that we eat, the longer we live. With the help of this enzymes other diseases or illnesses such constipation and gastroesophageal reflux disease or GERD will be prevented. Proper nutrition and exercise is the key to a healthy life (Garcia, B, (n. d).. References: Burton, G. R. W. (2004). Biochemistry: The Chemistry of life. Goucher, J.
