The Effects Of Farming On The Environment Environmental Sciences Essay

The Effects Of Farming On The Environment Environmental Sciences Essay By 5000 BC the Sumerians had developed core agricultural techniques including large-scale intensive cultivation of land,  mono-cropping, organized  irrigation, and the use of a specialized labour force. Intensive farming or  intensive agriculture  is an agricultural system that aims to produce maximum yield from available land. Besides, its also an  agricultural  production system characterized by the high inputs of  capital,  labour or heavy usage of technologies such as  pesticides  and chemical  fertilizers  relative to land area. You could say food is produced in large quantities with the help of chemical fertilizers and pesticides. The products such as eggs, meat and many agricultural products available in many supermarkets are produced using modern intensive farming. Intensive farming is practiced widely by many of the developed economies of the world. Sustainable intensive farming, intensive aquaculture, intensive live stock farming and managed intensive grazing fall under intensive farming. Environment issues of Intensive Farming Intensive farming may bring some issues to the environment. For instance:- Intensive farming includes the use of chemical fertilizers, pesticides, herbicides, fungicides and insecticides.  It is also associated with overpopulated animal farms, which are often associated with pollution and animal sickness. And even more disturbing is the fact that the majority of working farms use intensive farming. This means more chemicals on our plate at each meal. The use of such massive amounts of nitrogen based fertilizers contaminates the area lakes and rivers. Forests are destroyed to create large open fields and this could lead to soil erosion and affects natural habits in the forest. The pesticides sprayed on crops destroy pests, contaminate the crops and kill good insects. Eventually, these chemicals are passed on to the human beings.   The fruits and vegetables bought from farms that promote intensive farming are covered with invisible pesticide. These are not easily washed off. The residue of the pesticide affect the health of human beings.   Use of pesticides has numerous negative health effects on workers who applied those, people that live nearby the area of application or downstream from it and consumers who eat the pesticides which remain on their food. INTENSIVE FARMING IN MALAYSIA Livestock farming in Sabah once seen as backyard farming and pose no threat to the environment, but with the rapid development in the livestock industry, particularly in monogastric subsector, coupled with rapid expansion of urban and peri-urban area, livestock farming has become the critical issue. Excessive livestock waste as a result of intensive farming system need to be addressed. Although animal waste can be utilized as a manure to improve the physical and chemical properties of soil, it can also cause environmental hazard if not managed properly. It can caused malodour or odour nuisance to environment, surface water contamination, secondary pollution and also religious sensitivity. Table 1. Estimated Livestock Population of Sabah, 1999 Species Number (Head) Cattle 44,837 Buffalo 50,741 Goat 37,285 Sheep 1,900 Pig 100,000 Chicken 3,400,000 Duck 113,000 Source: (Anon.1999b) Livestock Species Population Waste Produce (m.t.) per Year Poultry 2.4 millions 178,000 Duck 0.5 millions 55,000 Pig 85,000 248,000 Cattle/Buffalo 97,000 1,416,000 Goat/Sheep 38,000 70,000 Total 1,967,000 Source: (Mokhtar and Chia, 2000) Table 2. Total livestock population and the wastes produced per year The rapid growth of the livestock industry caused on environmental problem-related to the livestock waste generated from the intensive farming system. Livestock waste generated from an extensive or semi extensive farming system does not seem to cause any major environmental problem as shown in table 2, cattle or buffalo wastes amount to 1.4 million metric ton compare to pig wastes about 248,000 metric ton. The problem is further aggravated with the rapid development of the urban and peri-urban area where most of the livestock farms are situated. The total livestock population and the waste produced per year for selected animal is illustrated in Table 2. Environmental problems cause by livestock farming Water Pollution Main environmental problem cause by livestock farming is water pollution, according to The Malaysian Environmental Quality Report, 12 rivers in the state were polluted with ammoniac nitrogen (NH3-N) due to livestock farming and domestic wastes in 1997. Water pollution cause by livestock farming occurred due to malfunction of waste lagoon or accidentally spill over from flooded lagoon or deliberate flushing of wastes directly into river system. Water may turn reddish brown and may destroy the fragile ecosystem. Pollution from nutrients contained in animal manure, namely phosphorous and nitrogen is one of the most serious problems, leading to excess algae growth, robbing water of oxygen which may lead to mass destruction of fish. Air pollution The anaerobic decomposition of stored animal wastes generates various volatile metabolic compounds of which a dozen contributes to odour, in particular hydrogen sulphide (H2S) and ammonia. These can cause continuous source of strong, persistent and unreasonably offensive hog/poultry odours. The resulting of air pollution is interfering with surrounding areas. Air pollution in the form of ammonia nitrogen can cause respiratory illness in the neighborhood up to two miles away from the site. Potential source of diseases Beside serious environmental problem, animal waste also may become a source of various diseases such as infectious worm larvae hatched from the worm eggs passed out with the faeces; contamination encrusted with organic matter is an ideal breeding ground of harmful bacteria. Arthropods such as flies, lice, fleas that are attracted by animal waste may trigger outbreak of infectious diseases, because they are the vectors to transmit diseases such as viruses, rickettsiae, protozoa and helminthes. WAYS TO PREVENT There are several ways to prevent Environmental problems cause by livestock farming, fr instance:- To minimize environment problem caused by pig waste there should be proper animal waste management system such as improving the housing adopting by the Pit Recharge System and Concrete Floor unit.   The adoption of the Sequencing Batch Reactor (SBBR) with an Automation, which is waste water treatment system with the function of stirring, aeration and settling.     To reduce the odour emitted from farm, a close housing system with regulated ventilation is used. Thats mean, by using high efficiency fans at one end of the building; fresh air is sucked ion from outside environment passing through the cooling pad to reduce the temperature before being delivered into the building. Livestock Farming Rules, 2001. In the meantime the Department of Veterinary Services and Animal Industry is well aware of the need to control and rectify irregularities in the livestock farming practices. Base on this, Livestock Farming Rules, 2000 (Draft) was introduced. This regulation was created under the existing Animal Ordinance 1962 (Amended 1998). Under this legislation, all livestock farms shall be operated under the permit of Department of Veterinary Services and Animal Industry, Sabah (DOVSAI). CONCLUSION Intensive farming or  intensive agriculture  is an agricultural system characterized by the high inputs of  capital,  labour or heavy usage of technologies such as  pesticides  and chemical  fertilizers  relative to land area. Intensive farming is practiced widely by many of the developed economies of the world. However, it may bring disadvantages to our environment. Livestock farming has become the critical issue. The rapid growth of the livestock industry in Sabah caused on environmental problem-related to the livestock waste generated from the intensive farming system. Excessive livestock waste as a result of intensive farming system need to be addressed. If not managed properly, it can caused malodour or odour nuisance to environment, surface water contamination, secondary pollution and also religious sensitivity.

Slip of the Tongue in Singing English Songs: a Psycholinguistic Analysis

INTRODUCTION Since slip of the tongue is the naturals condition that everyone find during his communication experience, people finally give many definition toward this phenomenon. In Cambridge Advaced Learner’s Dictionary slip of the tongue define as a condition when someone says something that they did not intend to say which is means the slip of the tongue is not intentional and it can not represent the true feelings of a person. On the other hand the opposite definition coming out from Sigmund Freud which is explain slip of the tongue as a meaningful and interpreted utterances.The utterances coming out as the representation of the restrained or repressed intention of the speaker. Both definitions have their own strength and approval but here, the concern of the research just limited on the reason or factors that cause slip of the tongue and the relation between rhythm/music genre to human ability in producing words under psycholinguistics analysis perspective. One condition that everybody have to understand is the research take a special condition. If slip of the tongue usually happen in normal conversation in this case slip of the tongue will observed in the sing activities.The reason for this condition is related to the concern of the research which will find the relation between rhythm/ musik genre to human ability in producing words. So, the researcher find five different songs in different genre to be analyzed and in collecting data, observational method and recorcing technique used while in analyzing the data researcher used articulatory identity method and presenting the result using informal and formal method. METHODS The data taken from five english songs which is sing by adult and the object that researcher need to find is the slips of the tongue by adult in singing those songs.In order to find the object of the research firstly the researcher have to find the songs that included into the criteria that explained in the background of the rese arch. In this case, the researcher have to make a questionnaire to collect some information about the genre and the popular singer and songs that known by the participant. Then after collecting those information the researcher have to decide five songs that included into the chategories by collecting the most similar answer by the participants. After collecting five songs as the tools of the bservation,the researcher need to record the songs that is sing by the participants so, if we relate it to Sudaryanto’s book (1988) the method used by researcher in collecting the data is observation and the technique used is recording. Nevertheless in devining the tools of the data researcher need to use questionnaire as the technique. This research included into descriptive qualitative research because the data were collected in the form of utterances that produce by the second singer (adult) and the representation of the research is in the form of words.Due to this research purpose are to find the kinds and factors of slip of the tongue that cause slip of the tongue by adult as the second singer while singing a song so, the reseacher will use descriptive research because it designed to obtained information concerning the current status of the phenomenon and directed toward determind the nature of the situation as it exists at the time of the research in the label of qualitative methode (Ary 1972:259) Differ from quantitative research, this research will concern on the complex and larger concentration.The researcher of qualitative research have to give a meaning for the phenomenon holisticaly and need to play arole in the whole process (Sudarwan, 2002). The research it self will approve the phenomenon with the perspective of the researcher so, there should be a methode used to analyze the data taken. Lately many expert use triangulation method to analyze the data. This methode is a study aplication that used multimethodic for analyze the similar phenomenon, (Denzi n,1989 in Sudarwan, 2002).According to Denzin and Kimchi there are five types of triangulation : theoretical triangulation, triangulation data, metodological triangulation,investigator triangulation and triangulation analysis (Sudarwan,2002:38). Then this research will focus only theoretical triangulation which is means that the researcher will combine some theory from the different aspects of linguistics such as psycholinguistics, phonology, morphology and syntactic perspective to analyzing the data.After analyzing the data, researcher present the result of analysis by using the informal and formal method. Informal method is a way of presenting the findings by using a verbal statement (natural laguage) while a formal method is a way of presenting the analysis by using signs and symbols (artificial language). THEORY In linguistics, language production is the production of spoken or written language. It describes all of the stages between a concept and translating the concept into li nguistic form. Levelt, 1989) As Fromkin and Ratner (1998) argued when we produced an utterance there is a correspondence between our thought and wishes which convey the message but when the storage space of the brain is finite we may never produce a number of the infinete sentence. From those explanation we know that we must construct sentences from smaller parts or units before we are able to say them. The main issues then concern on the processes by which units come to be selected and then combined in a particular order. (Gleason and Ratner 1998) The production of spoken language involves three major levels of processing.The first is conceptualization. The speaker must decide the message to be conveyed. It is also called the preverbal message or the message level of representation. This stage is often represented by a thought bubble. It means that this level connects the intention to speak and the concepts to be verbally expressed. (Levelt 1989) On the other hand, Jaeger (2005:8) proposed this stage which also includes not only general and specific world knowledge but also the speakers’ knowledge about the linguistics pragmatic conventions of their speech community.Therefore speakers must take account of what they called the â€Å"common ground†. The common ground between two people consists of their mutual beliefs, expectations, and knowledge. If someone overhears a conversation between two friends, it can be very hard to follow, because s/he has a lack common ground. The second level is formulation. Levelt (1989) stated that the speaker must convert their message into a linguistic form. The process of formulation is the creation of the linguistics form of the idea meant to be expressed.This process also known as the processes of grammatical encoding, starting from lexical component selection which is activate the message and it includes semantic and syntactic properties. (Jaeger, 2005:8) Then, the last is articulation / execution. The speaker have to make a plan of the motor movements to convey the message. It also involves detailed phonetic and articulatory planning (Levelt, 1989). Errors in Articulator Program According to Clark and Clark (1977), there are types of errors occur with a number of different linguistics units.In some cases, a single phoneme is added,deleted, or moved, but at other times, it may be sequence of phonemes, morphemic,affixes and root, whole words, or even phrases. As general rule, errors tend to occur at only one linguistics level per utterance. That is, when a person clearly says the wrong word, as in substitutions, the syntactic structure of the sentence, prosodicstructure, and phonological structure remain intact. According to Fromkin and Ratner (1998) such errors in production is called speech error. It regularly occurs in normal conversation. A speech error is a pattern that differs from some standard pattern.Speech errors are common among children who have yet to refine their speech, and can frequently continue into adulthood. They sometimes lead to embarrassment and betrayal the speaker's regional or ethnic origins. However, it is also common for them to enter the popular culture as a kind of linguistic â€Å"flavoring†. There are nine types of speech error: silent pauses, Filled pauses, repeats, false starts (unretraced), False starts (retraced), Interjections, Stutters, Slips of the tongue. Later on this research will not discuss all of the kind of the speech error but just focus on slip of the tongue.According to Fromkin (in Clark, 1977) slips of the tongue have occurred when the speaker’s utterance differs in some way from the intended utterance. Jaeger (2005) defined slips of the tongue as one-time error in speech production planning; that is the speakers intends to utters a certain word, phrase, or sentence but in the middle of planning process the utterances came out of the mouth differ from the intended words which want to say. Freud argued t hat slip of the tongue is in which a mistake in speech reveals something of the nature of the speaker's unconscious or semi-conscious desires.He proposes that when somebody misspeak, it is an accidental expression of thoughts or feelings. Freud would argue that slips of the tongue were never accidents, that they always revealed some underlying unconscious or repressed need to impulse. In Freud’s mind, this verbal slip could not have been accidental or based on any explanation other than the indispensable condition of suppression he had proposed. Furthermore, this suppression of intent or impulse which they made in the cornerstone of all slips of the tongue could operate at three different levels.On one level, the suppression could be conscious and deliberate on another suppression, it can be identified afterward by the person who made the slips but was not intended beforehand, and at the deepest level the person absolutely denies the suppression. For Freudians, it really does not matter what level the person made a slip of the tongue is operating at. For them in all cases, the slip is the results of the conflict between two forces-the underlying unacceptable need and the tendency to keep it hidden. According to Dell (as cited in Paulisse, 1999), slips of the tongue unintended,nonhabitual deviations from a speech plan.Slips of the tongue happened in three levels Those are in sound errors, morpheme errors, and word errors. Sound errors are accidental interchanges of sounds between words such as â€Å"snow flurries† might become â€Å"flow snurries†. Morpheme errors are accidental interchanges of morphemes between words. For example â€Å"self-destruct instruction† might become â€Å"selfinstruct destruction†. Word errors are accidental transpositions of words. For example: â€Å"Writing a letter to my mother† might become â€Å"Writing a mother to my letter†. Major types of slips of the tongue according to Carol: . Shift In Shift one speech segment dissapears from it appropriate location and appears somewhere else. Example : That’s so she’ll be ready in case she decide to hits it (decides tohit it); get its (gets it); 2. Exchange In effect,double shift, in which two linguistic units exchange. Example : Fancy getting your model renosed (getting your nose remodeled); writing a mother to my letter (writing a letter to my mother); slicely thinned (thinly sliced); 3. Anticipation occur when a later segment takes the place of an earlier one. Example : Bake my bike (take my bike); eading list (reading list) sky is in the sky (sun is in the sky); 4. Perseveration Occur when a earlier segment replaces a later item. For instance He pulled a pantrum (tantrum); beef needle (beef noodle); 5. Addition A unit is added for example : I didn’t explain this clarefully enough (carefully enough); to strained it (to strain it); 6. Deletion A unit is deleted. For instance : same sate (same sta te); I’ll just get up and mutter intelligibly (unintelligibly); 7. Substitution A unit is changed into a different unit. Example : At low speeds it’s too light (heavy); 8. BlendBlend occur when two speech units are combined. For instance : That child is looking to be spaddled (spanked/paddled). The thing that we have to considered here is slip of the tounge is a condition where the utterance is not utter correcty based on the idea of the speaker. In this case the proces of producing sounds was broken in the last phase ( articulation phase) where human produce the sound to speaking. So, based on the reality above in analysing the data we have to combining some linguistics brances and in this case the are psycholinguistic, phonology and morphology and also syntax. ANALYSISFrom the explanation above here are some data taken from the participant when they are singing English song. Table 1 TitleIf I Die Young If I Die Young Singer The band PerrySecond Singer (Indonesian) Ge nreRockRock Lyrics The sharp knife of a short life, well I've had, just enough time. (1a) The sharp knife of a short life, well I've have, just enough time. (1b) From the tabel above we can see that : I’ve had I’ve have had have /h? d//h? v/ Both of /d/ and /v/ in the table of phonetic symbols take place as fricatives, flat and voiced. Nevertheless â€Å"d† included as the sound in dental alveolar while â€Å"v† in the labio dental sounds.So, in this case a dental alveolar sound changed by a labio dental sound. Table 2 TitleMake Me StrongMake Me strong SingerSami YusufSecond Singer (Indonesian) GenreNasyidNasyid LyricsMy lord show me right from wrong Give me light make me strong I know the road is long make me strong (2a)My lord show me right from wrong Give me right make me strong I know the road is long make me strong (2b) Based on the data above the change is happen on sentence 2a Give me light replaced by the Give me right in the 2b sentence Give me l ight Give me right light right /lait//rait/Both /l/ and /r/ are voiced liquids sounds in dental alveolar thing that make them differ is the position of producing the sounds /l/ take place in lateral and /r/ in the central. Table 3 TitleMy Heart Will Go OnMy Heart Will Go On SingerCeline DionSecond Singer (Indonesian) GenrePopPop LyricEverynight in my dreams (1) I see you, i feel you That is how I know you go on Far across the distance And spaces between (2) us You have come to show you go on (3a)Everynight in my times (1) I see you, i feel you That is how I know you go on Far across the distance And spaces minween (2) usYou have come to show you go on (3b) from the tabel we get that 3a. 1 becomes 3b. 1 and 3a. 2 changes into 3b. 2 for clearence let we see the explanation below. 3a. 1 Everynight in my dreams Everynight in my times 3b. 1 dreams times / driems/ /taims/ 3a. 2 And spaces between usAnd spaces minween us between minween /bi’twien//minwien/ /b/ is a billabial stop vo iced sound meanwhile /m/ is billabial nasal voiced sound then /t/ is dental alveolar stop voiceless sound and /n/ is dental alveolar nassal voiced sound.Both changes happen in the same place such as /b/ replace by /m/ which are take place in billabial but /b/ is stop but /m/ is nassal then the next /t/ replace by /n/ both are in dental alveolar but /t/ stop voiceless and /n/ nasal voiced. Table 4 TitleLove StoryLove Story SingerTaylor SwiftSecond Singer GenreCountryCountry LyricWe were both young when i first saw you I close my eyes and the flashback starts (1) I’m standing there on a balcony in summer air (2) See the lights, see the party, the ball gowns (3) See you make your way through the crowdAnd say hello Little did i know (4) (4a)We were both young when i first saw you I close my eyes and the Flash starts (1) I’m standing there on a Galcony in summer air (2) See the lights, see the party, the ball gains (3) See you make your way through the crowd And say hello L ittle i know (4) (4b) In this song the researcher find 4 changes toward the song. They are : 4a. 1 replaced by 4b. 1 I close my eyes and the flashback starts I close my eyes and the Flash starts flashback flash /fl? sy’b? k//fl? sy/ 4a. 2 replaced by 4b. 2I’m standing there on a balcony in summer air I’m standing there on a Galcony in summer air balcony galcony /b? lkenie/ /g? lkenie/ /b/ is a billabial stop voiced sound which is replaced by /g/ palatal stop voiced. 4a. 3 replaced by 4b. 3 See the lights, see the party, the ball gowns See the lights, see the party, the ball gains gowns gains /gawns//geins/ 4a. 4 replaced by 4b. 4 Little did i know Little i know After explaning the changes above, now the researcher try to clasified the problems into the kinds of slip of the tongue. 1. Deletion :Deletion is a kind of slip of the tongue where one item are deleted in the data above we find it in the data number 4. (4a. 1 replaced by 4b. 1) â€Å"I close my eyes and the flashback starts become I close my eyes and the Flash starts† Here â€Å"flashback† become†flash† which is means â€Å"back† are deleted The next data is 4a. 4 that replaced by 4b. 4 â€Å"Little did i know become Little i know† . In this sentence ‘did’ are deleted 2. Substitution: I've had, just enough time become I've have, just enough time Everynight in my dreams become Everynight in my timesGive me light make me strong become Give me right make me strong And spaces between us become And spaces minween us I’m standing there on a balcony in summer air become I’m standing there on a Galcony in summer air See the lights, see the party, the ball gowns become See the lights, see the party, the ball gains These six data are included in substitution class because all of them get a consonant error or vowel eror such as 4a. 3 replaced by 4b. 3 â€Å"ow† replaced by â€Å"ai† gowns gains /gawns//geins/ The n other get a phological error such as 4a. 2 replaced by 4b. 2 /b/ replaced by /g/ balcony galcony b? lkenie/ /g? lkenie/ For the replaced of the sounds the pattern are not define yet because each people has their own problem in replacing the sound and it is need more data for defining the pattern of the replacing phonemes. Nevertheless the reason that influence the second singer get slip of the tongue could be analyse based on some theory from the expert. Before executing an utterance we have to make a plan in our brain first. A speaker builds up a general structure for the discourse, form a skeleton for the sentence to be uttered and select words to fit the skeleton constituent by constituent.In speaking, people take already formulated plan and execute them but not all goes well in every speech. In practice, they have fundamental problems. First, they have formulated their plans fully before they begin their execution. For this reason, they often speak fast and start to make varie ty of speech error. Second, in final preparation for execution, they must build an â€Å"articulator program†, a plan in working memory that tells the articulator muscles what to do them (Clark and Clark 1977) Clark also says that the planning takes time and more time on some occasions than others.The more difficult the planning, the more time it should take and the more likely speech itself will be disrupted. Then, when slip of the tongue occurs here are some factors that influence it; 1. Cognitive Difficulty The first factor of planning difficulty is called cognitive difficulty. Taylor in Clark and Clark (1977), conducts a study in which people were asked to produce as quickly as possible a sentence on topic like â€Å"car, animal, pleasure, and dominance† some of these are concrete objects (car and animal) and others are abstract (pleasure and dominance).It took people longer to produce the first word of the sentence from an abstract than from the concrete one. Furt hermore, it took them longer to develop a sentence skeleton for an abstract topic. 2. Situational Anxiety Situational anxiety is the second factor of slips of the tongue. When we talk about topics that we are anxious about, we tend to produce more silent pauses and certain other speech errors. One possibility is that anxiety disturbs the planning and execution processes generally. If speakers become tense, their planning and execution become less efficient.Another possibility is that what the speakers talk about is simply more difficult cognitively when s/he is anxious. It may be very difficult to verbalize the more time planning, groping, for just the right words. Under this alternative anxiety, pauses have the same source as the pauses of any other cognitively difficult talk (Clark and Clark 1977). The same cases also happen when people singing a song. When the song is familiar and interest the singer the process of production the words will easier than the one who does not.Then t he frequency of error will higher in in the singer who does not like the songs. 3. Social Factors The next factor that influences slips of the tongue is the social factors. Under the pressures of conversations, the speaker must take clearly whether they still have something to say or they are finished. On other hand, there are some factors that errors can occur. Those are low self confidence and the environment factor which in this case is family (Wirawan, Seputar Indonesia No. 135/1 Sunday 14th May 2006). Here, the pressure coming out from the music.The music itself has a rhythm which is conducting the repetition of the sounds in the certain pattern or design. Then the next is the tempo of the music which is defines as the time or the speed of the song. Then the last one is the sound of the singer which influences the second singer to duplicate their pronunciations while singing. CONCLUSION Slip of the tongue define as a condition when someone says something that they did not inten d to say which is means the slip of the tongue is not intentional and it cannot represent the true feelings of a person.On the other hand the opposite definition coming out from Sigmund Freud which is explains slip of the tongue as a meaningful and interpreted utterances. The utterances coming out as the representation of the restrained or repressed intention of the speaker. Nevertheless in this research most of slip that occur usually coming out because the second singer feels very familiar with the sound and produce it without paying too much attention or the opposite reason is the song is not familiar so the singer trying very hard to understand the meaning and try to imitate the first singer and the result is s/he get a big pressure while singing.For sure, those reasons are explained in the three factors that influence the occurrence of slip of the tongue: cognitive difficulty, situational anxiety, and the last one is social factors. Then the kind of error/slip of the tongue tha t is occurring mostly are deletion and substitution because the most reason for the slip of the tongue are the pressure and the interest toward the song.

Rousseau And The Social Contract - 1503 Words

Rousseau The Social Contract The Social Contract is a political work written by Swiss philosopher Jean-Jacques Rousseau that theorized the best way to establish a sovereign political community in the face of the problems within a divided commercial society. The Social Contract helped inspire political reforms or revolutions in Europe; most notably in France. Furthermore, Rousseau’s argument was against the idea that Monarchs were divinely empowered to legislate; in his opinion only the people who are sovereign have that all-powerful right. Rousseau’s aim in writing The Social Contract is to determine whether there can be a legitimate political authority, since peoples’ interaction with government left them worse off with their freedoms â€Å"restrained† by the society created by their political leaders. With this stated purpose I believe that Rousseau’s ideas are to a great extent liberal and cry out for the people of this time to take a stand and voice their will towards a corrupt system of government and gain back their natural freedoms. â€Å"Man was born free, and he is everywhere in chains. Those who think themselves the masters of others are indeed greater slaves than they† (Rousseau, pg. 49). With Rousseau’s beginning statements he establishes an unjust link between government and the people it governs revealing that the natural rights of the people have been either taken or modified to fit the agendas of men who are slaves to the power they mandate.

Feminist Perspectives in a Story of an Hour Essay example

Feminist Perspectives in a Story of an Hour A Woman Far Ahead of Her Time, by Ann Bail Howard, discusses the nature of the female characters in Kate Chopin’s novel’s and short stories. Howard suggests that the women in Chopin’s stories are longing for independence and feel torn between the feminine duties of a married woman and the freedom associated with self-reliance. Howard’s view is correct to a point, but Chopin’s female characters can be viewed as more radically feminist than Howard realizes. Rather than simply being torn between independent and dependant versions of her personality, â€Å"The Story of an Hour’s† Mrs. Mallard actually rejoices in her newfound freedom, and, in the culmination of the story, the position of the woman†¦show more content†¦When Mrs. Mallard is finally offered the opportunity to throw off the burdens of marriage and accept a new life of independence, she â€Å"breathed a quick prayer that life might be long. It was only yesterday she had thought with a shudder that life might be long†. This suggest a strong contrast between Mrs. Mallard’s view of the position of the married and non-married woman. In one case she would almost rather die; in the other, she embraces life with zeal. This truly proves that Howard’s characterization of the roles and duties of the nineteenth century married woman are precise and well reflected in the case of Mrs. Mallard. Howard’s argument falters, however, when she fails to recognize the truly radical feminist scope of Chopin’s characters and the messages that she seeks to impart. For example, at one point Howard asserts that â€Å"Chopin makes no suggestion that Mrs. Mallard would not mourn for her husband, a man she loved, a man apparently cut off by a railroad accident in the prime of his life†. While it is probably true that Chopin did not wish to alarm readers by directly declaring that Mrs. Mallard did not or would not mourn for her dead husband, something really is amiss when Mrs. Mallard â€Å"did not hear the story as many women have heard the same, with a paralyzed inability to accept its significance. She wept at once, with sudden, wild abandonment, in her sister’s arms.

Bells Chemicals Coursework Free Essays

Bells Chemicals is at present facing a major problem that it had never faced since its inception. As I have been given the responsibility to sort it out, I will work to the best of my knowledge and capabilities in arriving at an appropriate decision. The four-member team appointed to decide which of the two machines (Chemex and AFU) to purchase for its oldest product – Preserve, has not been successful in doing so. We will write a custom essay sample on Bells Chemicals Coursework or any similar topic only for you Order Now All the four members have their own viewpoints and the situation has become very confusing. The machines in the Preserve unit have not been replaced ever. They were performing well all these ten years, but now there is breakdown of one of the machines. There are two choices for the company i. e. buying the Chemex machine (the one that was being used all these years) again or to go for the new AFU unit. Arriving at a correct decision is the problem. Had the company made an autocratic decision there would have been no need to consult its key professionals. But this approach would have been termed unfriendly. The friendly approach has some of the disadvantages like the current dilemma. However, keeping aside other things, coming up with a perfect solution is the need of the hour now. I think the company should go for the Chemex machine. This decision of mine can be characterised as the rational way of decision-making. The Normative Decision Making model i. e. defining a problem and rigorously working around it has helped me in arriving at this decision. I have optimized as much as possible to come to a decision beneficial to the organisation. The rational approach of problem solving is the path I have taken. Main body of the report Mr. Steve Bell is not much interested in getting funds from outside. Especially when the company had recently financed most of its capital investments from its own retained profits, for products and capital investments for other products of the company. Capital required to install a new Chemex machine is much lower than the AFU unit. Not only this, by installing the Chemex machine the company will also be saved with the hassle and stress of taking its first short term loan. The funding of regular operations of the company all round the year will get affected as the company has exhausted accumulated profits in developments and expansion of other products. Hence this financial year, internal funding is a major issue too. Operating cost of AFU unit is extremely expensive when compared to the operating cost of the Chemex. machine. At the present market stage it is impossible for the company to cover additional cost of ? 18000 as operating cost against advantages, which are not very well defined. If we go through the viewpoints of the marketing manager we can derive the following information about our present and expected market. †¢ Company’s production need for current market: 90000 Kg †¢ Company’s production need for expected market: 100000 Kg †¢ Annual market need for current market: 200000 Kg †¢ Annual market need for expected market: 250000 Kg When compared to the production and selling cost estimate of ? 320 per Kg for AFU unit to production and selling cost of ? 350 for Chemex machine, the AFU unit brings forward a brighter picture. Also with the AFU unit production and selling cost can be reduced by ? 2700000 a year at current production rate but we cannot neglect the high acquisition and operating cost attached to the AFU unit either. Retaining present market share should be the current goal of the company keeping in mind the emergence of new competitors in the market. The chief chemist has been trying to modify the product; Preserve so that it can be used in wider ranges of food products, but has not been successful yet. The increase in market demand at this market stage can also not be predicted. Therefore demand for increase in production is out of the way. Hence for the next couple of years it is advisable to install a new Chemex machine instead of the AFU unit to satisfactorily cover the market growth. Why to waste money on an expensive machine when a cheaper one can meet the requirements successfully? Quality is one of the major issues for the marketing manager with new competitors in the horizon. The marketing manager will naturally aim to increase, or at least retain his market share for the best benefits. If the AFU unit is installed then, there will be a major quality inconsistency. Chances are that the other Chemex machine that is giving good performance and the new AFU unit will produce different qualities of the same product. This is quiet normal because two different machines can give different end results. The integrity of the company will become questionable then. Customers will find two different items in two similarly packaged products. They might react negatively in this situation and chances are they might even turn to the products of our competitors. This is a big price to pay if AFU is installed. Installing AFU unit has one advantage and that is – it does not require expenditure in quality control as it has an automatic quality control system. On the other hand the recruited technicians of the company do the quality control of the Chemex machines. They are the regularly paid staff. With the installation of the AFU unit they will have to be paid the same money for half of the their actual work. Their salary cannot be cut down as chances of revolt in the company can erupt because they will never allow a cut in their salaries for no fault of theirs. Hence from this angle too it is a more intelligent step to go for the Chemex machine instead of the AFU unit. Keeping the high cost of the AFU unit, its maintenance will probably be good but we cannot be sure without testing it. Chemex machines require regular maintenance but this is not a problem for the company. Since Chemex is a local company, any breakdown is immediately rectified. After working with the Chemex machines for such a long period of time, the technicians have also become experts in handling its minor problems to a great extent. But the breakdown of the AFU unit will become a major headache for the company for sometime. Each time anything will go wrong, the company will have to get totally dependent on its manufactures who are not local like that of the Chemex machines. A lot of time will get wasted in all this. Keeping this factor in mind, again the Chemex machine scores over the AFU unit. Another major concern is the after sales service. After Sales Service of Chemex has been tested and they have always satisfied the company so the future is secure with this supplier. This cannot be said in the AFU’s case at the moment. I have applied Creative Decision Making model, Optimizing model, Kralijic’c Purchasing model and of course the Normative Decision Making model while arriving at the decision regarding the purchase of the correct machine. Through Creative Decision Making model I recognized the problem after going through the case study. By going through the viewpoints of the four key members of the SMG team, I coherently arranged the information regarding the two machines. I analyzed the whole problem from different angles with the help of the information I had gathered and arranged. I came out with multiple solutions of the same problem. Then I went through all the alternatives one by one and chose the most correct option. Through the Optimizing model I was able to optimise the alternatives of the problem situation. Since this model is similar to the Creative Decision Making Model and the rational approach that I took, things became easier to sort out. According to Have et. al. (2003, p. 115) â€Å"The Kralijic’s (1983) purchasing model and the variations developed over the last decades help management select the most appropriate purchasing strategies for different types of products, thereby optimizing the trade-off between cost and risk. Costs include both the direct and indirect cost of purchasing, for example, management time, and trouble shooting and drawing up contracts. Two basic dimensions are included in Kraljic’s matrix: †¢ Impact on financial result †¢ Supply risk (or uncertainty)† I went through this approach too, to arrive at a strong and appropriate decision. Since requirement of this report was to base it on the Normative Decision Making model I followed the following steps while approaching the decision: †¢ Defining of the exact problem †¢ Setting of the objectives †¢ Identifying the alternatives †¢ Evaluating appropriately †¢ Making choice of the best alternative †¢ Sensitivity Analysis †¢ Arriving at the best decision Recommendation I recommend the company to go ahead and purchase the Chemex machine. By doing so the company would not only be paying attention to the profitability of the company, financial viability of the decision but also the satisfaction level of its entire staff. The customer will also remain loyal to the company because they will not find any inconsistency in the products they have got used to since the past ten years. The members of the SMG team who were pro AFU unit will also agree with me if they go through this report as at this stage when we have limited resources and growing number of competitors we should stick to the theory that ‘the old is gold’.

Air polution Essay Example For Students

Air polution Essay Air pollution is nothing new. Ever since the discovery of fire, less-than-desirable substances have been vented into the air. One of the first air-pollution regulations dates back to the fourteenth century, when King Edward I banned the burning of sea coal in lime kilns. U.S. air-pollution regulations have their roots in British Common Law. But regardless of those efforts, air pollution continues to be a serious local and world-wide problem. Pollution is the pressure within the air of one or more substances that are harmful to human health, welfare, animal or plant life, or property. In the past with air pollution we included mainly the outdoor pollutants, although in recent years this is not the case. Today we separate pollutants in to two categories. Primary pollutants, because they come directly from various sources, and secondary which are by-products of chemical interactions of the primary pollutants within the atmosphere. Although air pollution might be thought of as unwanted g ases in the atmosphere, two of five primary pollutants are really solid substances called particulates. Soot has always been a sure indicator of a polluted atmosphere, but other than soiling and a negative psychological effect, soot cant settle into the lungs and cause serious diseases. Thick ,black smoke coming out of a stack is that what we think causes the pollution, but what really creates the damage is what we cant see. Particles like this are called suspended particles. They come from many incomplete burning and can consist a variety of substances. The most harmful type of particulate is so small that that it is microscopic. All the particulates are harmful for several reasons. When inhaled, they can damage the interior of the lung; they can also be poisonous. Sometimes gases will glue to their surfaces and in a process called adsorption they can reach the lungs. All these particles are mainly products of combustion. The major sources include industrial processes, power plants that are both coal and oil-fired, residential heating, and transportation. But coal burning is the greatest source. Table 1 below shows estimates of U.S. particulate emissions from various sources. National U.S. Emissions Estimates-1990 SOURCE PARTICULATES SULFUR OXIDES CARBON MONOXIDES Only 13% of the total is generated by transportation. Industrial sources account for nearly three times as much as 37%. Fires account for just about as much particulate emissions as transportation. That amount is matched by combustion from sources, which include the generation of all heat and electricity. When coal was the main source to generate energy, power plants and homes accounted for much greater contribution. The switch to oil and nuclear power has lowered those concentrations, but it hasnt been without its own problems. In addition to health-related problems, particles can damage materials through corrosion and erosion, as well as soiling. Particles can also impact the weather, through chan ges in visibility, and even in enhancing precipitation. Studies around major urban areas show an increase in precipitation and in thunderstorms with hail downwind from downtown areas. The weather modification is localizes but definite, and may be related to an increase in the large condensation nuclei that the particles provide. Lead particulates are brutal primary pollutant. Their presence in the atmosphere has diminished sharply during the past 29 years. Since 1975, the concentration of lead has decreased by more than 90%, which can be directly linked to the elimination of lead from gasoline. The following table shows that huge drop. Another primary group of pollutants consists of the surfur oxides(Sox), and the major contributor is SO2, a sulfur dioxide. This is generated whenever sulfur is burned, most often where fuel with a high sulfur content is used. Coal can have very high sulfur concentrations, as can some oil. Overall, coal and oil are the major sources for sulfur oxide p ollution. The vast majority of this type of air pollution comes from generation of heat and electricity. These stationary sources account about 80% of all sulfur oxides. Transportations contribution is minor, about 5%. The rest comes from industry. Sulfur dioxides cause damage to vegetation and material. Plants lose their chlorophyll which is the plants food factory. But the most damage appears when sulfur oxides combine with other substances. Because of its solubility, sulfur dioxide becomes a major contributor to acid deposition. Leaves are bleached and show damage. Tree growth is stunted and vegetation dies. Damage to vegetation occurs at concentrations lower than what is harmful to people. Carbon monoxide is colorless, odorless , tasteless,non-corrosive, highly poisonous gas of about the same density as that of air. It is very flammable, burns in air with bright blue flame. Its melting point is at-205.0 C and boiling point is at -191.5 C. There is no way to know if it is around, except we may no feel so well. When a fire burns in an enclosed space, oxygen is gradually depleted and carbon dioxide is increased. The changes in both of the these gases increasingly cause the combustion process to change from one of complete combustion to one of incomplete combustion, resulting in the release of increasing amounts of CO. Thus, even a perfectly designed and adjusted furnace or water heater (or any kind of combustion device) will eventually begin producing toxic/lethal amounts of CO if it operates in a closed space and/or where insufficient fresh air is available. Table three lists some of the effects of CO to humans.

The early air pollution laws were passed within small communities and concerned the color and density of the smoke that comes out from the stacks. They first appeared in Chicago and Cincinnati and later on began to show up also in other communities. A special chart determined the level of smoke. The chart showed smoke with different shades of gray and black. At a particular level violations would be set. No national air pollution legislation appeared until the 50s. The first federal legislation appeared in 1955 when the Air Pollution Control Act was passed. In 1965 the Motor Vehicle Air Pollution Act was passed, establishing national automobile emission regulations for the first time. Then the Air Quality Act of 1967 was passed, providing funds for additional federal research and designating air quality control regions to help establish air pollution criteria. Another goal of this act was to research the cost -effectiveness relation of available engineering control techniques. Later, during the 70s National Air Quality Standards were set for the major pollutants. Primary standards were set for health, with secondary standards for vegetation and general environmental welfare. Penalties as high as $25.000 per day and a year in prison were authorized for industries that failed to meet the regulations. Automobiles emission standards were set. Additional adjustments to the 70s regulation came along in 1990. Each revised some of the older regulations. Some of which proved to be very strict and unattainable. Overall each new version strengthened and broadened the previous version. The most direct method of pollution co ntrol involves changing the fuel. High sulfur coal was responsible for the greatest smog outbreaks of the early twentieth century. Sulfur oxides and particulates reached dangerous levels in many areas, especially in industrial areas. During the 1960s and 1970s a switch to low sulfur oil, natural gas and nuclear power brought the levels of that kind of smog down to relatively low concentrations. Although complex control devices are available, the fuel switch in power plants accounts for most of the improvement. Of course change can introduce new problems. Natural gas combustion can increase the levels of nitrogen oxides, and nuclear power leads to new problems. Although we know that changing the fuel is not going to stop air pollution, but only reduce it, we are trying to find substitutes which will result to higher efficiency with lower emissions. Particles come in assorted sizes and shapes, and a number of control systems have been designed for removing them from the stream of gase s that go up the smokestack. The type of device depends on the type of particle and size. Soluble particles can be drained out of an effluent by washing with scrubbers. Sometimes, the particles will simply settle out before being emitted, in what are called settling chambers. Sometimes the gas is pushed through filters of cloth collectors. Other devices are even more sophisticated. The gas might be whipped around in a circular path, so that centrifugal force separates the particles. Those devices are called centrifugal separators. An other type of device is the electrostatic precipitators. This device delivers an electrical charge to the particles. An opposite charge is placed on a metal plate, and, because opposites attract, the particles will collect on the plate. Then the plate is cleaned off. Of course all these devices remove the particles, but once the particles have been removed the problem becomes how to dispose of the sludge. The toxicity of the material and its impact on t he environment become new considerations. One of the greatest polluters on Earth is the automobile. Volatile organic compounds, nitrogen oxides and carbon monoxides are the major pollutants that come out of a cars exhaust. If the air-fuel mix is lean, there is a good deal of air and less fuel. The combustion temperature will be relatively high, which will favor the complete burning of the gases, and hydrocarbons will convert to water vapor and carbon dioxides. However if the mixture is not so lean, but richer with more fuel the temperature will be lower. Instead of completely burning the hydrocarbons with the oxygen, you end up with unburned hydrocarbons and carbon monoxide instead of carbon dioxide. So the conclusion here should be to have a very lean mix of air and fuel. The problem with that is the high temperature of efficient combustion. The oxygen and nitrogen in the air combine, resulting in a lot of nitrogen oxides. You may reduce the carbon-monoxide pollution in having a tr ansformation to carbon dioxide, but on the other hand, you re going to end up with more nitrogen oxides. Any hydrocarbons that dont burn can now combine with nitrogen oxides under strong sunlight to deliver photochemical smog. That is one of the major dilemmas of the internal combustion engine. There are control devices that can eliminate some of the pollutants from the internal combustion engine, most notably the catalytic converter. It raises the temperature of gases that will be exhausted, so there will be further burning of the hydrocarbons. As a result we end with more water vapor and carbon monoxide. Once exposure levels have been set, steps can be undertaken to reduce exposure to air pollution. These can be accomplished by regulation of man-made pollution through legislation. Many countries have set controls on pollution emissions for transportation vehicles and industry. This is usually done to through a variety of coordinating agencies which monitor the air and the environm ent. A significant problem that has to deal with all the changes is the cost. A company that has to install million dollar electrostatic precipitators may have a serious economic problem with pollution control But in general, the overall costs of not controlling air pollution are far greater that the collective costs of pollution control. The problem of course is the concentration of costs within specific industries. Creative techniques of distributing that cost could go a very long way in maintaining our standard of living while having good and healthy air to breath. Only through the efforts of scientists, business leaders, legislators, and individuals can we reduce the amount of air pollution on the planet. This challenge must be met by all of us in order to assure that a healthy environment will exist for us. In our businesses, communities and as individuals, we can make meaningful reductions of air pollutants and gases. In many cases, one action will reduce both air pollutant an d gas emissions. Home energy improvements, ride-sharing, alternative transportation, and tree planting programs are just some of the community-based solutions to reducing air pollutant and gas emissions. A typical automobile will emit more than 40% of its own weight in common air pollutants in one year, and four times its weight in greenhouse gases. So for those necessary trips by car, make sure that it is a well-tuned, energy-efficient model! Also, avoid idling our engines, as restarting an engine uses less fuel than ten seconds of idling. Other actions we can take at home and at work include: Turn off energy-using equipment (lights, computers, or any machinery) when it is not in use. Make your home more energy efficient through improved insulation, caulking and weather-stripping. Recycle, since it takes much less energy to create a new product using recycled materials than using raw materials. Compost kitchen scraps and yard waste, because organic waste in landfills creates gases that contribute to climate change. Plant trees around our home. Its a natural way to insulate, and trees help clean the air and slow climate change. Marilyn Monroe Essay Bibliography:
