A Dolls House by Henrik Ibsen Assignment Example | Topics and Well Written Essays - 750 words
A Dolls House by Henrik Ibsen - Assignment Example It criticised the attitude towards marriage prevalent in the 19th century (Krutch, 1953).Ibsen wrote the play drawing inspiration from his real time friend Laura Kieler a successful writer herself (Tornquvist, 1995). Nora, the heroine of Ibsen's play chooses to abandon her family and children for the sake of self-respect and self-search. This climax raised several agitations among the then conservative society. Ibsen was widely acclaimed for supporting the sprouting women rights organizations. But, he promptly denied any claim of honour for contributing to the movement and declared his play was just "the description of humanity". Ibsen's A Doll's House is considered as the first play to portray realism on stage, rather than stage historic and epical events. The play created a whole new wave, which led to the production of several realism related plays in the 18th century. Ibsen acquired international fame with his other plays like 'Ghosts' in 1881 and 'An Enemy of the People' in 1882 . Ibsen had a unique talent to explore the psychological side of the normal people. He always made his characters do what the normal people do not dare to do in real life fearing practical difficulties. Ibsen's later plays like Wild Duck and Hedda Gabler concentrated on psychology and various inner secrets in the human mind. As Michael Meyer claims, even ââ¬ËA Doll's Houseââ¬â¢ do not entirely stand for women's rights. ... The alternative ending was shown in many theatres especially in Germany. The film version of the play portrays Nora as a simple woman just like in the play. The scenes where Trovald refers to Nora as a "sulky squirrel" in the play was omitted in the film. Nora is shown conversing with the delivery boy in the play. But, there is no such scene in the movie. The relationship between Kristine and Nora is displayed as a very formal one in the movie while a little depth is added to the same via wordings and gestures in the play. Nora is not shown elaborating much about her secret to Kristine in the movie. A Doll's House was filmed several times into feature films and TV adaptations. The most prominent one among them is the 1959 TV version created by George Schaefer. Julie Harris plays Nora Helmer the main protagonist and the part Trovald Helmer her husband is played by Christopher Plummer. The film has only two acts in contrast with the play which has three acts. The background, sets and t he portrayal of the house in the movie are very much similar to the descriptions in the play. The wording and dialogue are nearly the same except for few minor differences. Nora is shown entering the house with her three children in the movie while her children are introduced much later in the play. Krogstad, depicted as an immoral man, blackmailing Nora is shown is portrayed as a much lighter character in the movie. He simply pushes her hard to save his own employment, but gives in when he finds the love of his life in Kristine. Trovald Helmer is portrayed as a dominating husband who tries hard to retain his position as the head of the household. His confusion and helplessness when Nora walks out on him is displayed beautifully by Christopher Plummer. Antony

Discussion Board 6 - Assignment Example NASA was blamed for creating a cover up story as well as creating complex aircrafts and recognizing the risk without taking necessary precautions while BP did not get much blame for remaining true to the disasterââ¬â¢s outcome even though they ignored the risks behind their oil drilling project. (47). The oil industry spends most money on researching for safe drilling operation while ignoring the possible outcome of a disaster spillage (Meredith & Mantel, 2012). For instance, BP spends approximately 29 million dollars in a span of 3years on the research of safe drilling methods. Robert Wine, the companyââ¬â¢s spokesman admitted that the company does not invest on oil spill cleanup researches but support the non-governmental ââ¬Ëoil spill response organizationsââ¬â¢. (48). Million dollar firms have public relation departments whose primary purpose is to respond to emergencies. For instance, the NASA took much of the blame from the Gulf oil spill due to its reaction to the disaster (Meredith & Mantel, 2012). In this case, multibillion dollar firm have public relation departments whose role is to respond to emergencies thus preventing the companies from incurring losses when responding to disaster. (49). The NASA and FMEA have both similarities and differences in there in their approach to risk. Both the NASA and FMEA have ways of protecting the might fail. They also have ways of estimating the likelihood of a fail (Meredith & Mantel, 2012). Both firms have ways of estimating the likelihood of failure occurrences and severity of the mission. However the FMEA has devised possible ways of protecting the might fail while NASA has not gone to such

TV Personalities Essay Example for Free
TV Personalities Essay For this project, I chose the television show House. In this particular episode, Dr. House and his team of doctors face the problem of diagnosing a man who came into the ER at the hospital after fainting. There are no clear symptoms that point to a single medical diagnosis. The second part of this episode deals with House and his best friend Wilson. Wilson is in a relationship with another doctor that House doesnââ¬â¢t particularly like and House is determined to get his fair share of time with his friend, away from his girlfriend. I have obviously chosen Dr. House has my subject for this paper. House is a very brilliant and gifted doctor. He is also very obnoxious, overbearing, rude, egotistical, sarcastic, arrogant, and cantankerous. House will gather his team to brainstorm about what the symptoms that patient is showing to see if they can come up with a solution and House will override everything they say. He will ask for a vote on the way to proceed and then disregard the vote for whatever he wants. Looking at Freud, it would appear that Houseââ¬â¢s id is still very strong and was not tempered very much by the Ego and Superego. House is still very demanding, irrational, illogical and impulsive in the way he lives his life. By studying Freud, it would also seem that in the stage of the Superego that House failed to fully develop the ego ideal and the conscience. The Behavioristââ¬â¢s view would show that the way House is today is a result of environmental stimulus that was reinforced or strengthened in some way while he was growing up. It would suggest that his parents might have praised him when he acted out and was disrespectful instead of properly chastising or punishing him. The social cognitive view of personality suggests that House has a high self-efficacy. He is very sure of his talent as a doctor and therefore excels at his job. This view of personality also will show that House is very comfortable in his environment. Because of his comfort level, his behavior of being rude, sarcastic, and so on, will continue because he receives the type of reaction from others that it seems like he expects. This theory suggests that if the environment changes, his behavior should adapt to the change. In this episode, the only time his behavior changed in any way was when he was out with his friend Wilson. Although he was still sarcastic, overbearing and obnoxious, it was not as bad as when he was in the hospital. Houseââ¬â¢s real self and his ideal self are pretty well matched when looking at the humanistic perspective. House is very confident and sure of himself in what he is and who he wants to be. According to Rogers, House would be a fully functioning person. When House was growing up he must have received unconditional positive regard from his parents. The last personality theory that will be touched upon will be the trait theories. The one trait theory will be scrutinized is the Big Five. House is definitely an extrovert. He obviously likes being the center of attention. This was shown by the way he directed the attention to be on himself whenever he gathered his team of doctors together. House would also score very low on the trait of Agreeableness. House was very rude, irritable, and aggressive. A very high score would be given to House on Openness. House shows that he would have to be very curious and imaginative when looking for the causes for symptoms that patients emit and finding a diagnosis and cure for those symptoms. House was also very nonconforming. House definitely did not conform to the expectations of the way a doctor should conduct himself, whether with other colleagues or with patients themselves. House would also score high on Conscientiousness. He might not be the easiest person to be around, but he is very reliable. He would also have to be an ambitious person to become the brilliant doctor that he is. Neuroticism is hard to decide. Although House shows that he can be very temperamental, which is a characteristic for the higher score, it did not seem that he exhibited the traits of worrying, insecurity, and anxiousness. On the flip side, the low scoring characteristics for Neuoticism are calm, secure, relaxed and stable. House could probably be described as stable, but the other characteristics donââ¬â¢t really match him either.
Analysis Of Collocations, Phraseology And Idioms
Analysis Of Collocations, Phraseology And Idioms In our life we often meet situations when people use idioms and collocations. We can hear when somebody says: something is dead sure or I have to keep a tight rein on Tom. Young people often think what does it mean? or How can we translate it?. People have huge problems in the translation of phraseology. Grammar problem is common, because there are several constructions of grammar poorly understood. Very often it is not clear how they should be represented, or what rules should be used to describe them. I would like to mention that in English one linguistic form can be used to encode of meaning while in Polish form and meaning usually are conditioned by each other. English speakers usually choose lexemes very broad in meaning to encode a message. Idioms, collocations and phraseology very often are used in business language, for example: to launch a campaign. We should know basic collocations, phraseology and idioms if we want to understand foreign languages. It can really help. On the other hand it is very important to study the relation between English and Polish phraseology and their culture. In the first part, I will present typological classification of bilingual dictionaries, theory of bilingual lexicography, function of bilingual dictionaries, target group or users, translation problems between Polish and English language, phraseology, expression, vallency collocation, loose collocation- basic terms, types of collocations. The second part contains a precise description of the dictionary included in my work. The third part has the character of dictionary and consists of a systemized extract of collocations with their English equivalents. Typological classification of bilingual dictionaries A bilingual dictionary or translation dictionary is a specialized dictionary used to translate words or phrases from one language to another. Bilingual dictionaries can be unidirectional, meaning that they list the meanings of words of one language in another, or can be bidirectional, allowing translation to and from both languages.(Al-Kasimi 1983: 10) Bidirectional bilingual dictionaries usually consist of two sections, each listing words and phrases of one language alphabetically along with their translation. In addition to the translation, a bilingual dictionary usually indicates the part of speech, gender, verb type, declension model and other grammatical clues to help a non-native speaker use the word. ( Hartman 1998: 25) Dictionaries can be classified into various types of the basic of different criteria. To begin with we have to differentiate between dictionary proper and dictionary like works. Zgusta (1971) calls these linguistic and non-linguistic dictionaries respectively. The linguistic dictionaries are concerned with the words or lexical units of languages and they are called word books. The non-linguistic dictionaries are not concerned with words but with realia or denotata (thing)) they are called encyclopedias, or thing books. They are similar to dictionaries only in their alphabetical arrangement of words denoting the realia. Anyhow the aspects of the realia which are called encyclopaedic features such as description, photos, diagrams etc., are given in certain types of dictionaries to add to the utility of the dictionary. Classification of linguistic dictionaries has been attempted by a number of scholars such as Shcherba (1940), Sebok (1962), Malkiel (1959); Cornym (1967), Zgusta (1971), Svensen (1993). (Devapala 2004 : 2) Bilingual dictionaries have become a necessary part of our daily economic, intellectual, and cultural activities. A new system of classifying bilingual dictionaries, help language teachers to select the most appropriate dictionaries for their students. In 1934 Mansion noted that bilingual dictionaries are not scientific in their treatment of words, and have not kept pace with progress in philology.(Al-Kasimi 1983 : 85) There are many kinds of dictionaries such as glossary, concordance, vocabulary, word book, index, linguistic atlas, encyclopaedic dictionary. The classification of bilingual dictionaries: (Al-Kasimi 1983:12-13) Dictionaries for the speakers of the source language vs. dictionaries for the speakers of the target language; Dictionaries for production vs. dictionaries for comprehension; Dictionaries of the literary language vs. dictionaries of the spoken language; Dictionaries for the human user vs. dictionaries for machine translation; Historical dictionaries vv. Descriptive dictionaries; Lexical dictionaries vs. encyclopaedic dictionaries; Genaral dictionaries vs. special dictionaries The classification of bilingual dictionaries that are combined with machine translators on the Language Grid. The dictionaries on the Language Grid can be classified into the following three types: (WawrzyÃâ¦Ã¢â¬Å¾czyk 1996: 8) Global Dictionaries: This type of dictionary is a Web service that provides the standard interface of a bilingual dictionary. Further, such types of dictionaries are registered on the Language Grid. In addition, Global dictionaries are large-sized bilingual dictionaries either specialized for certain domain or general purpose and are shared between the Language Grid Users (e.g., Online Dictionary of Academic Terms); Local Dictionaries: These are also Web services with a standard interface; however they are not registered on the Language Grid. These are large-sized dictionaries specialized for a certain user and are not open to the other Language Grid users. (e.g A Dictionary for NPO Pangaca) Temporal Dictionaries: These dictionaries unlike the other two types, are not Web services and are only accessiblefrom a users application system. These are typically small-sized dictionaries specialized for a certain user and are not open to the other Language Grid users (e.g. Users Dictionary for Language Grid Playground) (Al-Kasimi 1983: 28). A bilingual dictionary can combine a number of the defining features of these contrasts in accordance with the purpose it is intended to serve. 1.2 Theory of bilingual lexicography This part is concerned with selected problems in bilingual lexicography. Lexicography is divided into two related disciplines: Practical lexicography is the art or craft of compiling, writing and editing dictionaries. (Fontenelle 2008: 45) Theoretical lexicography is the scholarly discipline of analyzing and describing the semantic, syntagmatic and paradigmatic relationships within the lexicon (vocabulary) of a language, developing theories of dictionary components and structures linking the data in dictionaries, the needs for information by users in specific types of situation, and how users may best access the data incorporated in printed and electronic dictionaries. (WawrzyÃâ¦Ã¢â¬Å¾czyk 1996 : 36) This is sometimes referred to as metalexicography. General lexicography focuses on the design, compilation, use and evaluation of general dictionaries, i.e. dictionaries that provide a description of the language in general use. Such a dictionary is usually called a general dictionary or LGP dictionary.(Hill 2002: 9) Bilingual lexicography is occasionally given an important place in lexicography. Most lexicographical literature is focused on monolingual dictionaries, and most often monolingual lexicography is considered to be the proper one. (WawrzyÃâ¦Ã¢â¬Å¾czyk 1996: 42) Practical lexicographic work involves several activities, and the compilation of really crafted dictionaries require careful consideration of all or some of the following aspects: Profiling the intended users (i.e. linguistic and non-linguistic competences) and identifying their needs, Defining the communicative and cognitive functions of the dictionary, Selecting and organizing the components of the dictionary, Choosing the appropriate structures for presenting the data in the dictionary (i.e. frame structure, distribution structure, macro-structure, micro-structure and cross-reference structure), Selecting words and affixes for systematization as entries, Selecting collocations, phrases and examples, Choosing lemma forms for each word or part of word to be lemmatized, Defining words, Organizing definitions, Specifying pronunciations of words, Labeling definitions and pronunciations for register and dialect, where appropriate. (Hartman 1998:29) One important consideration is the status of bilingual lexicography, or the compilation and use of the bilingual dictionary in all its aspects. In spite of a relatively long history of this dictionary type, it is often said to be less developed in a number of respects than its monolingual counterpart, especially in cases where one of the languages involved is not a major language.(WawrzyÃâ¦Ã¢â¬Å¾czyk 1996: 45) Not all genres of reference works are available in interlingual versions, e.g. LSP, learners and encyclopedic types, although sometimes these challenges produce new subtypes, e.g. semi-bilingual or bilingualised dictionaries like Hornbys (Oxford) Advanced Learners Dictionary English-Chinese, which have been developed by translating existing monolingual dictionaries. 1.3 Functions of bilingual dictionaries Bilingual dictionaries have many functions. They are used for many tasks and by different groups of users: learners, translators, scholars. Bilingual dictionaries are used in order to aquire some knowledge about one or both of the languages, knowledge which is necessary above all for communication. Students need a good bilingual dictionary to help in their reading of simplified materials in the foreign language. A good bilingual dictionary is an indispensable tool for the student in the intermediate stage of foreign language learning. Some scholars argue that bilingual dictionaries are very inadequate and unnatural because they present words out of their natural elements-context, they put together items which hardly ever occur in the same communicative situation. According to A. Hill (2006) the ideal dictionaries are still and will always be, essential not only in a dictionary prepared for pedagogical purposes, but in only other dictionary as well. These five types of information are: the phonemic structure of word, in morphemic structure; the grammatical modification is undergoes, its syntactic habits, and its meanings. (Hill 2006: 20) A good dictionary should be different for foreigner students of the language and for the native speakers. (Al-Kasimi 1983: 55) 1.4 Target groups or users Users belong to different groups such as children, students, teachers, scientists, trainees, technicians etc. Hartman (1195) classifies the needs of the users into two types (Hill 2006:56): Information: It is one of the factors for the users seek to help of a dictionary to check spellings, meaning, synonyms, pronunciation, etymology. Operations: That is, when the user performs tasks as reading, writing and translating.He refers to the dictionary to find words and meanings. From the point of view of types of users and their two types of needs, dictionaries fall into different categories such as dictionaries for children, students, translators, learners, scholars, creatives writes. Categorisation of the dictionaries from the point of view of user, influences the articulation of the work in the collection of material, selection of entries, choice of defining words while constructing the entries etc. Therefore, this is an important factor in dictionary making and the compiler has to clearly decide on the type of the users and their needs. 1.5 Translation problems There are some particular problems in the translation process: problems of ambiguity, problems that originate from structural and lexical differences between languages and multiword units like idioms and collocations. Another problem would be the grammar because there are several constructions of grammar poorly understood, in the sense that it isnt clear how they should be represented, or what rules should be used to describe them. (Schmalstieg 1969: 20) The words that are really hard to translate are frequently the small common words, whose precise meaning depends heavily on context. Besides, some words are untranslatable when one wishes to remain in the same grammatical category. Language problems: (Schmalstieg 1969:45) Idioms terms and neologism, Unsolved acronyms and abbreviations, Proper names of people, organizations, and places, Slang difficult to understand, Respect to punctuation conventions. English speakers usually choose lexemes very broad in meaning to encode a message. In contrast, very broad lexemes do not occur in Polish frequently, i.e. Polish: English: SzyÃââ⬠¡ sukienkÃââ⠢ make (sew) a dress 1.6 Phraseology and collocations-basic terms Phraseology appeared in the domain of lexicology and undergoes the process of segregating as a separate branch of linguistics. The reason is clear lexicology deals with words and their meanings, whereas phraseology studies such collocations of words (phraseologisms, phraseological units, idioms), where the meaning of the whole collocation is different from the simple sum of literal meanings of the words, comprising a phraseological unit. (Altenberg 1998:17) Phraseological units are (according to Prof. Kunin A.V. 1970) stable word-groups with partially or fully transferred meanings (to kick the bucket, Greek gift, drink till alls blue, drunk as a fiddler (drunk as a lord, as a boiled owl), as mad as a hatter (as a march hare)). (Altenberg 1998: 25) A phraseological unit is a lexicalized, reproducible bilexemic or polylexemic word group in common use, which has relative syntactic and semantic stability, may be idiomatized, may carry connotations, and may have an emphatic or intensifyi ng function in a text. (Cowie 2001: 10) A collocation is two or more words that often go together. These combinations just sound right to native English speakers, who use them all the time. On the other hand, other combinations may be unnatural and just sound wrong. Look at these examples: Natural English Unnatural English a quick shower a fast shower 1.7 Types of Collocation There are several different types of collocation made from combinations of verb, noun, adjective etc. We can distinguish: petrified collocations, vallency collocations and loose collocations. Petrified collocations function in the utterance as single words. They might be replaced by a single word equivalent or by equivalent collocation to fulfil a semantic function. (M.K 2008, 9) Valency collocatons have a considerable degree of cohesion but their components did not submit to lexicalization. Valency characteristic are for example: Polish English WysunÃââ⬠¦Ãââ⬠¡ Ãâ¦Ã ¼Ãââ⬠¦danie put forward a claim (Ãâ¦Ã ¼Ãââ⬠¦daÃââ⬠¡) (claim) Loose collocations are formulated only by the concrete necessity of what the speaker intends to say. There are various possibilities for combinating single words to create a loose collocation.(J.B 1993, 19) A phrase in grammar, a phrase is a group of words functioning as a single unit in the syntax of a sentence. For example, the house at the end of the street is a phrase. It acts like a noun. It can further be broken down into two shorter phrases functioning as adjectives: at the end and of the street, a shorter prepositional phrase within the longer prepositional phrase. At the end of the street could be replaced by an adjective such as nearby: the nearby house or even the house nearby. The end of the street could also be replaced by another noun, such as the crossroads to produce the house at the crossroads. Most phrases have a central word defining the type of phrase. This word is called the head of the phrase. Some phrases, however, can be headless. For example, the rich is a noun phrase composed of a determiner and an adjective without a noun. 1.8 Types of phrases Phrases may be classified by the type of head taken by them: Prepositional phrase (PP) with a preposition as head (e.g. in love, over the rainbow). Languages using postpositions instead have postpositional phrases. The two types are sometimes commonly referred to as adpositional phrases(J.B 1993; 14). Noun phrase (NP) with a noun as head (e.g. the black cat, a cat on the mat) Verb phrase (VP) with a verb as head (e.g. eat cheese, jump up and down) Adjectival phrase (AP) with an adjective as head (e.g. full of toys, fraught with guilt) Adverbial phrase (AdvP) with an adverb as head (e.g. very carefully) 2. POLISH ENGLISH PHRASEOLOGICAL DICTIONARY 2.1 THE AIM OF THE DICTIONARY A phraseological dictionary is a special type of dictionary in which all entries function as collocation. Collocation is the way in which some words are often used together or a particular combination of words used in this way.(M.K, 2008, 5) The aim of Polish-English Phraseological Dictionary is to provide a broad range of phraseological vocabulary and give guidance on words which can be used with a headword. The source of Polish collocations is primarily Phraseological Dictionary of Polish Language by Skorupka ( S.S 1985;) and Phraseological Dictionary of Polish Language by Anna Ciesielska, Katarzyna MosioÃâ¦Ã¢â¬Å¡ek-KÃâ¦Ã¢â¬Å¡osiÃâ¦Ã¢â¬Å¾ska.(A.C 1990) In Polish phraseology there is a variety of expressions typical only of the Polish language. It is necessary to mention that not all English collocation given in my work reflect the exact meaning of the Polish ones.

Blind Obedience à à à à à While sitting in church on Sunday going through the same motions of every Sunday, my son leans over to ask, ââ¬Å"Why do we have to stand up for this prayer?â⬠My response ââ¬Å"because we are supposed toâ⬠. Reading ââ¬Å"The Childrenââ¬â¢s Storyâ⬠by James Clavell, made me think a little more about this question that I had no answer for. A person needs to be able to explain why he does what he does. Children are innocent and unknowing; they are like a blank piece of paper waiting to be filled up with drawings and ideas. This book shows just how easy it is to mold a child. It uses a classroom of children facing a major change in their lives as the setting. The story moves quickly and the characters are only briefly sketched out.

What to the Slave Is The Fourth Of July? Essay -- Fredereick Douglasss
Frederick Douglass's "Fourth of July" Speech is the most famous speech delivered by the abolitionist and civil rights advocate Frederick Douglass. It attracted a crowd of between five hundred and six hundred. Douglassââ¬â¢s speech to the slaves on the Fourth of July served to show the slaves that there is nothing for them to celebrate. They were not free and the independence that the rest of the country celebrated did not apply to them. In his speech he tries to make white people consider the behavior of black people. Specially their feelings towards a national occasion such as Independence Day. At the time of Douglassââ¬â¢s speech America were actually two different nations, white and black. Two separated nations one had great benefits after the independence and another still fight for basic human rights. What does the independence means for people who still suffer after it? This question is the most important. In the Declaration of Independence. He is implying that these rights are not being extended to African Americans. When this country was created it was meant to be a plac...
Dolphins: Communicators of the Sea
Dolphins are common creatures at rivers and seas. The majority of small toothed whales are dolphins. Dolphins are large sea animals making it part of the suborder Odontoceti, family Delphinidae. Whales and porpoises generally belong to the Cetaceans belonging to family Plantanistidae and Delphinidae, respectively. Often, people used dolphins and porpoises interchangeably denoting same species but porpoises in particular and dolphins are different species. Porpoises belong to family Phocaenidae; it has a rounded snout and chisel-liked teeth.While dolphins are under family Plantanistidae and Delphinidae, instead of a rounded snout, dolphins have beak like snout and sharp, conical teeth. Dolphins are outgoing creatures; often they are mingling in a group with two to fifteen animal members or more. Most of their communities are dominated by females, its offspring, sisters and other females. Sub adult male dolphins will leave these female-dominated communities to start a group of ââ¬Å"b achelorâ⬠dolphins; if these dolphins become sexually mature, they can move in the female groups for copulation. These mammals are very playful.They are often spotted riding the bow wave or stern wake of boats and ââ¬Å"surfingâ⬠on waves. Chasing and tossing things to one another is one of their favorite plays. If seen jumping or breaching, it indicates enthusiasm for these creatures. Play is important for dolphins for learning and as well as to practice their skills necessary for their lifeââ¬â¢s survival (Geocities. com, 2006). The current paper focuses on these creaturesââ¬â¢ characteristics, particularly their capability to engage in echolocation. Scope The paper begins with an introduction about the dolphin, and their general characteristics as sea creatures.This is followed by a discussion of their general physiology, including their skin, fin, swimming speed, breathing, and body temperature. The dolphin family is then discussed, with its 33 species ââ¬â with 5 river species and 6 porpoise species. Of these, the most popular is said to be the bottlenose dolphin which are found in theme parks and are featured in television programs. The next focus would be on the dolphinââ¬â¢s brainpower, specifically in their capacity to make tunes among themselves with a wide range of sounds. Their distinctive communication patterns are likewise expounded on.The paper concludes with a call for concern and protection from humans, who are supposed to be stewards of these creatures. Overview With regards to its general physiology, dolphins have rubbery skin. They are classified as mammals and have the capacity of maintaining high body temperature. They can hold their breath for several minutes making it easy for them to have rapid and deep dives of more then 300 m (1,000 ft). To date, there are more than 33 different species of dolphins, over 5 different species of river dolphins and more than 6 different species of porpoises.Though there are many species of dolphins, the most popular are bottlenose dolphins which are frequently featured in television and theme parks. Perhaps their greatest strength is their ability to communicate with one another or to echolocate. This is the counterpart of language among humans. Dolphins create whistles and sounds signifying an action for which another dolphin can understand, it can signal danger for their kind hence they should be alert or a prey is near at hand thus, everybody must prepare; depending on the whistle produced.They can make signature whistles that carry distinct information. Considering the cognitive abilities of bottlenose dolphins, their vocal learning and copying skills, and their fissionââ¬âfusion social structure, their communication process can be further studied to provide evidences about their ââ¬Å"dolphin messages and echoes. â⬠Humans have the responsibility of taking care of these creatures, acting as their stewards to prevent them from extinction. Gene ral Physiology of a Dolphin A dolphinââ¬â¢s body is smooth having a rubbery-feel of its hairless skin when touched.The skeletal remnants of five digits in the front appendage form the flippers mainly acting as its balancer during its swim. The rear appendages are almost absent because the small pelvic bones are deep-rooted in the connective tissue at the base of the tail (Dolphin Lovers. com, 2006). The subcutaneous dermal tissue of the dolphin forms its immovable dorsal fin; its tail fin is also dermal in its origin. Its movement is similar with the whales wherein the major force comes from its vertical oscillations of the tail and flukes making it capable to swim at a speed of 37-40 km/h, and in some events, its swimming speed reaches up to 48 km/h.Dolphins seem restless in traveling the rivers but in reality, it rides the bow wave by making use of the shipââ¬â¢s trust (Stoops, 1996) Dolphins are mammals, hence breathing and maintaining high body temperature is vital. Dolphi ns maintain its internal temperature at 36. 5 deg to 37. 2 deg C (97. 9 deg to 99 deg F), with its thick layer of dense fat (blubber) under the skin. At the top of its head, a single nostril or blowhole is placed where it acts as its lungs. Dolphins breathe air at the surface every two minutes consisting of brief unpredictable exhalation followed by a longer inhalation.Dolphins are capable to hold their breath for several minutes making it easy for them to have rapid and deep dives of more then 300 m (1,000 ft) (Dolphin Lovers. com, 2006). Dolphinââ¬â¢s Brainpower Greco and Gini (2005) say that dolphins are capable of making tunes among themselves with a wide range of sounds. Dolphins show evidence that their intelligence is greater than that of dogs. Dolphins learn easily and execute complicated tasks, continuous communications with one another, and their ability to mimic the sounds of human language if they are given ample time to be trained.Toothed whales have exceptionally la rge brains including the famously bright dolphins that have capabilities previously only attributed to humans and apes. Cetaceans (dolphins, whales and porpoises) and its ancestors acquired changes specifically in their brain through evolution. One of the reliable evidence to support this claim is by measuring the level of encephalization of a species or a taxonomic group. EQ is the measure of observed brain size relative to expected brain size derived from a regression of brain weight on body weight for a sample of species.EQ measures how much larger or smaller a speciesââ¬â¢ total brain size is from what is expected based on brain-body algometry (Greco et. al, 2003). Dolphins and humans share many common attributes. Both creatures are mammals wherein the young are born alive and not hatched from eggs. Air is important for both organisms since it sustains their breathing; the only difference is that dolphins must come up to the surface to breathe in its blowhole on the top of it s head and when it dives, the blowhole closes unlike humans that continuously breathe air in its respiratory system.Wang (1995) asserts that aside from being mammals, communication is one the major attributes keeping these two organisms at par with one another. Humans are capable of language and speeches denoting an idea or message for a particular person while dolphins create whistles and sounds signifying an action for which another dolphin can understand, it can signal danger for their kind hence they should be alert or a prey is near at hand thus, everybody must prepare; depending on the whistle produced.
