Mark TwainS Adventures Of Huckleberry Finn Essays - Literature

Mark Twain'S Adventures Of Huckleberry Finn they can really hurt. In Mark Twain's novel, The Adventures of Huckleberry Finn, Twain develops the plot into Huck and Jim's adventures allowing him to weave in his criticism of society. The two main characters, Huck and Jim, both run from social injustice and both are distrustful of the civilization around them. Huck is considered an uneducated backwards boy, constantly under pressure to conform to the humanized surroundings of society. Jim a slave, is not even considered as a real person, but as property. As they run from civilization and are on the river, they ponder the social injustices forced upon them when they are on land. These social injustices are even more evident when Huck and Jim have to make landfall, and this provides Twain with the chance to satirize the socially correct injustices that Huck and Jim encounter on land. The satire that Twain uses to expose the hypocrisy, racism, greed and injustice of society develops along with the adventures that Huck and Jim have. The ugly reflection of society we see should make us question the world we live in, and only the journey down the river provides us with that chance. Throughout the book we see the hypocrisy of society. The first character we come across with that trait is Miss Watson. Miss Watson constantly corrects Huck for his unacceptable behavior, but Huck doesn't understand why, That is just the way with some people. They get down on a thing when they don't know nothing about it (2). Later when Miss Watson tries to teach Huck about Heaven, he decides against trying to go there, ...she was going to live so as to go the good place. Well, I couldn't see no advantage in going where she was going, so I made up my mind I wouldn't try for it. (3) The comments made by Huck clearly show Miss Watson as a hypocrite, scolding Huck for wanting to smoke and then using snuff herself and firmly believing that she would be in heaven. When Huck encounters the Grangerfords and Shepardsons, Huck describes Colonel Grangerford as, ...a gentleman, you see. He was a gentleman all over; and so was his family. He was well born, as the saying is, and that's worth as much in a man as it is in a horse... (104). You can almost hear the sarcasm from Twain in Huck's description of Colonel Grangerford. Later Huck is becoming aware of the hypocrisy of the family and its feud with the Shepardsons when Huck attends church. He is amazed that while the minister preaches about brotherly love both the Grangerfords and Shepardsons are carrying weapons. Finally when the feud erupts into a gunfight, Huck sits in a tree, disgusted by the waste and cruelty of the feud, It made me so sick I most fell out of the tree...I wished I hadn't ever come ashore that night to see such things. Nowhere else is Twain's voice heard more clearly than as a mob gathers at the house of Colonel Sherburn to lynch him. Here we hear the full force of Twain's thoughts on the hypocrisy an cowardice of society, The idea of you lynching anybody! It's amusing. The idea of you thinking you had pluck enough to lynch a man!...The pitifulest thing out is a mob; that's what an army is- a mob; they don't fight with courage that's born in them, but with courage that's borrowed from their mass, and from their officers. But a mob without any man at the head of it is beneath pitifulness (146-147). Each of these examples finds Huck again running to freedom of the river. The river never cares how saintly you are, how rich you are, or what society thinks you are. The river allows Huck the one thing that Huck wants to be, and that is Huck. The river is freedom than the land is oppression, and that oppression is no more evident than it is to Jim. It is somewhat surprising that Huck's traveling companion is Jim. As anti-society that Huck is, you would think that he would have no qualms about helping Jim. But Huck has to have feelings that slavery is correct so we can see the ignorance of racial bigotry. Huck and Jim's journey begins as Huck fights within himself about turning Jim over to the authorities. Finally he decides not to turn Jim in. This is a monumental decision for Huck to make, even though he makes it on the spot.

Immune System and Disease essays

Immune System and Disease essays Today, our world is faced with many diseases. Some havent been discovered and some have no cures. The immune system fights off many of these diseases, but what happens when it fails us? One of the most deadly, incurable disease the world is faced with today is the Human Immunodeficency Virus (HIV). There is no none cure yet. Viruses cause colds and the flu. Viruses are microscopic particles that invade the cells of plants, animals, fungi, and bacteria. They often destroy the cells they invade. How do viruses reproduce? A virus first enters a cell in one of three ways: direct penetration, endocytosis, or membrane fusion. The virus takes over the cells machinery and is thus forced to make the viruss proteins and RNA. When the virus has entered, viral RNA is released in to the cell and reverse transcriptase occurs. Reverse trancriptase is when the cell makes a DNA copy of the viral RNA. It then produces the proteins and genes the virus needs to be assemble. The virus can then be released by three ways: lytic, lysogenic, and persistent. A virus, although not considered to be alive, does have a life cycle. First the virus attaches to a cell, which it recognizes by its surface markers. Then it penetrates the cell and gets inside. Next, it replicates and makes copies of itself. It then assembles itself back together and the new viruses are released. A virus cannot replicate by itself; it has to infect a cell. The virus is always the same size. It doesnt have a metabolism. A virus has three different shapes it can be: helical, polyhedral, and enveloped. It is made up of nucleic acid (RNA or DNA), and surrounded by a protein coat. Certain viruses can survive harsh conditions. Pathogens, disease-causing agents, have to enter the body to cause illness. There are several ways for them to get into the body: through the genitals, breaks in the skin, and natural openings. The immune system...

Genetic problems , down syndrome, hurlintong disease, diabetes, and Research Paper

Genetic problems , down syndrome, hurlintong disease, diabetes, and turner syndrome - Research Paper Example Sometimes errors can occur in the transmission of genetic material from parents to offspring or in the structure of the genetic material causing serious disorders in human beings. Structural chromosomal abnormalities arise when different enzymes are not able to repair several breaks in the pattern of chromosomes or even if they are able to do so these repairs are not specific enough to avoid the abnormality. These can be caused by chemicals, radiations, viruses, or any other type of abnormal event. These structural abnormalities are classified into four main classes respectively. These are Deletions, Translocations, Inversions and Ring Chromosome (Langman & Sadler 2006; Robbins et al 2005). Other names of deletion are gene deletion and deficiency mutation. Deletion is that type of genetic abnormality in which a sequence of DNA is absent in the chromosome or a part of chromosome is absent. It results in the loss of the genetic material from the chromosome. Translocation is also genetic aberration which occurs due to the rearrangement of the different parts of chromosome with nonhomologous chromosomes. Translocations are of two types that are reciprocal translocations and Robertsonian translocations. Reciprocal translocation is the translocation of genetic material between nonhomologous chromosome. These type of chromosomal translocations are harmless. When the two acrocentric chromosome fuse near the centromere resulting in loss of the short arm, this type of translocation is called Robertsonian translocation. In Robertsonian translocation the resulting karyotype in humans is 45 chromosomes. Inversion is that type of chromosomal abnormality in which a part of chromosome is split and introduced back to the same chromosome. Inversion is basically the aberration in a single chromosome itself and is not associated to other homologous or nonhomologous chromosome. Inversions are of two types paracentric and pericentric.

Organizational Politics slp Assignment Example | Topics and Well Written Essays - 500 words

Organizational Politics slp - Assignment Example In this case, six individuals wanted to be selected as the new sales manager, as a result, leading to a political battle. Political behaviour might be due to individual and organisational factors (Nair, 2010). Personal factors include the need for power, incremental reward, increase in scope of control and Machiavellianism. Organizational factors may be situational or organisational culture. Situation factors encompass performance evaluation, promotion seeking and resource allocation. In this case, there was a situational cause for the political behaviour as the workers were seeking promotion to the vacant position. Politicking arises because of the organisation culture whereby it is practised from the top management to the subordinates that was the case in the company. Some of the prospective staff members to the position went ahead tarnishing the other party’s credibility. It was through trying to reveal fraudulent activities that were they took part in the past. It led to some of the candidates getting disqualified and some were dismissed as well from the organisation after commission of enquiry set up found them guilty. If someone substantially invested in an organization, both emotionally or financially is likely to employ political behaviour due to care of the organisation’s destiny. Although politicking within the organisation is healthy, it also has its adverse effects as rift between employees’ increases. In this case, the working relationship within the organization became poor hence ultimately affecting the overall performance of the organisation In 2002, during the merger between HP and Compaq there was politicking within the board as some were opposed to the merger. The infighting was so bad that some of the board members leaked secretive information to the public. One of the main reasons for the conflict was the appointment of the CEO of the merged grouped. It led to

Chritiane Nords Notion of Function Plus Loyalty

Chritiane Nords Notion of Function Plus Loyalty INTRODUCTION The emergence of functionalist approaches to translation in the 1970s and 1980s was quite revolutionary in that it marked the move from what Munday (2001: 72) describes as the static linguistic typologies of translation shift, a term defined by Catford (1965: 73) as departures from formal correspondence in the process of going from the SL to the TL, to a consideration of the overall function of the Target Text (TT) in the Target Culture (TC). However, these approaches have been criticised on various grounds. This paper investigates one of these criticisms and whether Chritiane Nords notion of function plus loyalty adequately addresses the issue. SKOPOSTHEORIE As a term, functionalism is used to refer to the aggregate of approaches to translation that focus on the overall function(s) of a text or translation (Nord 1997:1). In other words, functionalism has been expressed or practised differently by different scholars and translators. However, they all appear to have drawn inspiration from what Vermeer has called skopostheorie, the birth of which apparently marked the beginning of functionalism (Honig 1997: 6). According to Vermeer (2004), [t]he skopos of a translation is the goal or purpose , defined by the commission and if necessary adjusted by the translator (236) and this notion of skopos can be applied in the translation process, the translation result as well as the translation mode (230). This skopos determines whether a text should be translated word for word or paraphrased or even adapted. As Nord (1997) puts it, the Skopos of a particular translation task may require a free or a faithful translation, or anything between these two extremes, depending on the purpose for which the translation is needed (29). Thus a single text can beget different translations according to the different translation briefs provided. This approach was quite novel in that it, to a large extent, addressed the eternal dilemmas of free vs faithful translations, dynamic vs formal equivalence, good interpreters vs slavish translators, and so on (Nord 1997: 29). However, it has also received quite a number of criticisms. One of such attacks came from Pym (1996) who questions the ability of functionalism to provide a basis for a professional ethics of translation. He then asks: Can such a theory generate a way of discerning between good and bad purposes, between good and bad translation strategies? Or is its aim merely to produce mercenary experts, able to fight under the flag of any purpose able to pay them? (2) Pym questions the apparent neglect of the ST, undue emphasis on the TT and the freedom skopostheorie gives the translator to produce any kind of text as dictated by the translation brief, whether or not the said brief is a far cry from the intentions of the author of the source text. In response to such criticisms, Nord added the concept of loyalty to functionalism. FUNCTION PLUS LOYALTY Chritiane Nord maintains that the loyalty principle is meant to account for the culture-specificity of translation concepts, setting an ethical limitation to the otherwise unlimited range of possible skopoi for the translation of one particular source text (2007:2-3). Loyalty is used to refer to the responsibility of translators, as mediators between two cultures, towards their partners namely, the source-text author, the client or commissioner of the translation, and the target-text receivers (Nord 2001: 185). It may also be seen as taking into account the intentions and expectations of all the partners in the communicative interaction named translation (195). Though the clients brief determines the skopos of the translation, it is not the only determining factor for the translation. The translator should be loyal to the ST author by ensuring that he not produce a TT that falsifies the authors intentions (Nord 2005:32). In other words, loyalty ensures some compatibility between the ST and the TT. The translator should also be loyal to the target audience, who have some expectations of what the translations should be like, by explaining in a footnote or preface how they arrived at a particular meaning, the thought-process involved. Nord distinguishes loyalty from fidelity or equivalence. While she sees the former as an interpersonal relationship between the translator and his partners, the latter she sees as concepts used to refer to the linguistic or stylistic similarity between the source and the target texts, regardless of the communicative intentions involved (2001: 185) HOW ADEQUATE? This section looks at the adequacy of Nords function plus loyalty principle to translation, especially in relation to Pyms accusation of skopostheorie producing only mercenary experts. In the first place, it checks the apparent freedom of the translator to produce any kind of translation in accordance with the clients brief. While function requires that the translation be modelled to fit into the brief provided by the commissioner, loyalty requires the translator to justify their choice of translation method by considering the interests of all the participants involved in the translation, not just that of the client. A translator should not produce a translation that goes contrary to the brief; they also should satisfy the expectations of the target audience as well as not falsify the intentions of the author. So if the brief betrays the communicative intentions of the author, it is then the translators duty to draw the attention of the client to this apparent anomaly. Pym (2007: 132) quotes Nord as saying that If the client asks for a translation that would mean being disloyal to either the author or the target readership or both, the translator should argue this point with the client or perhaps even refuse to produce the translation on ethical grounds. So the translator is not a mere mercenary since they do not accept whatever skopos is given them. Downie puts it this way: With the addition of the notion of loyalty the translator is now ethically and professionally responsible to either observe the expectations their partners have of their work or to tell them why these expectations have not been met (2), This principle reduces the number of skopoi that could be generated for a single translation text. Two questions may be raised against the loyalty principle, one of which has been partly answered in Downies quote above namely: is it always possible for every party to be made happy by the translator? According to Nord, the translator has the moral obligation not to translate on a brief that will falsify the authors intention. If after explaining the situation to the client and the client insists on not modifying the brief to make up for the defect, the translator has the moral responsibility to refuse to do the translation. Downie has already highlighted what the translator should do if the translation goes contrary to the expectations of the receiving audience. In Nords words, if the target culture expects the translation to be a literal reproduction of the original, translators cannot simply translate in a non-literal way without telling the target audience what they have done and why (1997: 125). This increases the level of confidence the audience has on the translator and makes them more ready to accept the translation as of a good quality even if their (the audiences) expectations are not met. This raises the second question: will the adoption of the documentary translation in situations where the source culture is markedly different from the target culture, seen in the additional explanations the translator has to make for the reader, not affect the reception of the work since the audience is aware that the text is not the original, but a translation? Though the reader might be affected by the realisation, the style shows that the translator has some respect for the reader and will help build their confidence in the translator for taking the pains to explain their strategy and choices. One other issue the loyalty principle addresses is the supposed dethronement of the source text. This is also one of the bases for Pym accusation of translators as being mere mercenary experts since the ST may result in TTs with which it shares a very tenuous relationship. Loyalty insists that the communicative intentions of the author be reproduced in the TT. And this can only be achieved when a detailed analysis of the ST is done to appreciate its place in the source culture, temporally and spatially. Nord insists that the interpretation of a text goes beyond the linguistic, that it is a product of the many variables of the situation (time, place, addresses) in which it originated (1997: 119), and that the analysis of extratextual factors such as author, time, place, or medium may shed some light on what may have been the senders intentions (125-6). The translator then does a similar extratextual study of the target situation to identify the expression that best reflects the author s intentions in the target situation. So in the main, the TT intentions are hinged on those of the ST. CONCLUSION It is axiomatic that a text is open to multiple interpretations, and translations. But Nords notion of function plus loyalty has indeed restricted the otherwise arbitrary production of translation briefs and translations that are a far cry from the message of the ST. It also weakens the criticism that functionalism advocates a dethronement of the ST. However, the satisfaction of every party involved in the translation process is only but an ideal, not always practicable. But loyalty has made the translator more responsible and conscious of their translations and increased the confidence of other participants on the translator. Indeed if translators will adhere to this charge of being loyal, the problems of mistranslations will be greatly reduced. REFERENCES Catford, J. C. 1965. A Linguistic Theory of Translation.

Horror of War Exposed in Dulce et Decorum Est Essay examples -- Dulce

Horror of War Exposed in Dulce et Decorum Est We have all heard war stories that seemed exciting and adventurous. Some stories are of men who gladly laid down their lives in the glory of battle and would do so again if given the chance. These stories tickle our sentiment and ease the pain of real war, but they do little to help us understand war's brutality. In his poem "Dulce et Decorum Est," Wilfred Owen does not attempt to pull the blood stained wool over our eyes. Instead of a novel quip, Owen gives us a look into the real horror of war. Using images of pain and sorrow, Owen gives us a taste of the front line that crushes any romantic ideas about war. Most of us envision soldiers marching into battle as upright, steady young men proudly bearing their ruck sacks and singing as they march. Owen paints us a picture of a different hue. Owen describes the men as, "Bent double, like old beggars under sacks." We see figures that are contrary to our preconceived notions ( 1). Owen's men of war are tired from the stress of battle and the weight of the inevitable doom that lies ahe...

Compare the Ways in Which Expected Roles Were Determined

Compare the ways in which expected roles were determined by gender in ‘Journeys End’ and ‘The Accrington Pals’. To what extent would you agree that ‘Accrington Pals’ presents a more credible image than ‘Journeys End’. A large proportion of Great War literature suggests that men were socially seen as the superior gender but women were given opportunities to prove themselves in a male-dominated society as a by-product of war. This essay will compare the issues of gender identity and roles at the front line in R.C Sheriffs ‘Journeys End’ and the impact war had on women who stayed home in Accrington, seen in Peter Whelan’s ‘The Accrington Pals’ during 1914 and 1918. ‘Journeys End’ appears to be a more credible drama because of Sheriffs first-hand experience of the war, where as ‘The Accrington Pals’ depicts the more emotional side of war. R. C Sheriff uses Stanhope as an example of how war affected young, intelligent and inexperienced men and showing the reality of war. Stanhope is the stereotypical male of WW1. He is the image of authority, power and patriotism.He is also thought incredibly highly of from the lower ranks. ‘He’s a long way the best company commander we’ve got’. It seems as though men were in the war for a long time but the reality being that the death rate of British officers was higher than that of the lower ranks with the average life expectancy of an officer being fourteen days. The word ‘long’ therefore creates irony within the drama. From the beginning of the drama, we are enlightened of Stanhope’s experience and dedication to his duty, however, Stanhope could be seen as a contradictory figure.His heavy drinking and reliance on alcohol may be a sign of weakness, which could also present Sheriffs use of realism in the drama. Stanhope is far from reluctant to admit he has a drinking problem . ‘Without being doped with whisky- I’d go mad with fright. ’ Sherriff’s own experience may have been reflected on in this dialogue as men at war used to seek comfort in things in order to avoid fright. It is apparent that this is the reason for Stanhope’s excessive drinking. Seeking comfort in something seen as sinful by society is also typical of Ralph from ‘The Accrington Pals’ who seeks contentment whilst away from his girlfriend, Eva Mason.At the beginning of the play, Ralph expresses love, affection and admiration for Eva; ‘clever woman! Eh? Brains! ’, which is why it seems disappointing when Ralph admits he has been unfaithful to her in whilst away at war, seen in the extract, ‘I’ve been a bastard to you Eva, if only you knew. Slept with whores’. Ralph, being a typical representation of a working class citizen suggests that war can turn even the most honourable man to adultery in the search for co mfort. It is almost as if Whelan sympathises with the fragility of men because of their previous innocence, horrific war and their apparent flaws.Through the use Stanhope and Ralph as characters the audience understand the expectations placed on men because of their class. Stanhope, being from the high rank in the military is ultimately granted respect from the lower ranks, whilst Ralph in ‘The Accrington Pals’ was from a lower class citizen and in a lower rank, thus the reason for C. S. M Rivers arrogance and lack of respect; ‘we don’t want you shooting yourself in the head. ’ C. S. M Rivers does not think Ralph is capable of the things man does in war, simply because of his class.The patriotic character of Stanhope in ‘Journeys End’ compares with Tom Hackford from ‘The Accrington Pals’, who illustrates comradeship throughout the entire drama. Despite his description in the preface being that he is ‘a dreamy, utopian idealist young man’, he does not seem typical of the average man of the war as he appears almost as a young boy, not knowing the horrific reality of what is to come. He is very dedicated to his future duty as a solider and seems excited to fight for his country, although this is not in the interest of May, who describes war with ‘that's a world you love isn't it’.As an audience, we gain an insight to Tom’s reasons for volunteering. This is ironic because he understands that he is soon to die but he describes signing up as a way to escape from Accrington for something new ‘free of here, of this place, of this town'. Being such a socialist creature; it can only be disappointing that war has limited opportunities for the male gender as many of the young men who signed themselves up such as Tom and Ralph whom had no idea of the reality of the trenches because of government censorship.Tom’s enthusiasm to his obligation is apparent throughout the dr ama, as seen in his letter he writes to May in scene two. ‘I hope you don’t mind me sharing it as we do all the parcels here’ Comradeship is proven as he shares his luxuries with the Pals. ‘I hope you don’t mind me sharing it’. Even near to his death, Tom still concentrates on sticking with one another to get through the war. The ideologies of Tom contrast to those of May Hassel, who is described from the outset of ‘The Accrington Pals’ as ‘a strong-minded, rugged individualist woman. The entrepreneurial spirit displayed through May’s independence and the leadership motive of the iron lady, suggest the advantages war gave women. Whilst the men are absent from Accrington, May is left focused on exploiting the chances now available, making her appear arrogant and cold hearted. May obsesses with business ideas and opts to making money out of the war. ‘I never believed that war would make a difference like this. The re’s money around’.The individual attitude and the drive to make money is not typical of the female gender role, therefore May does not present the normal values the contemporary audience are expecting from a woman. ‘The Accrington Pals’ suggests the more emotional side of war for women, showing the eventual downfall of May caused by the lack of male influence within war shaped society, however does strengthen May’s development as an individualist. The absence of Tom seems the reason for Mays change. Her development during the play into a more conventional and sensitive women (as seen in scene four act one).The change in Mays character can be seen when she offers to make the tea. She seems more lenient and positive. In ‘The Accrington Pals’, it is arguable that May Hassal conforms to the role that is often portrayed of women in the First World War: taking on the everyday roles of men while they were away. This expectation has been shown to us through literature from the time, such as Emmeline Pankhurst’s autobiography which gives the proof that feminism was now a feature of Edwardian existence.May suggests this as she is shown to be an individualistic, entrepreneurial ‘tartar’ (seen in conversation between the Pals). In this sense, however, May is shown to be more masculine, and has seemingly swapped roles with Tom who becomes more feminine. This can be determined by the labels that May gives him, such as ‘Dreamer’. However, these gender roles are once again returned to typical trends of society by the end of the play when May becomes feminised by Tom’s death. This seems to be portrayed as almost chaotic, and heroic.Rivers says, ‘But our Tom was a hero †¦ , a madcap scarecrow ripping his way out of the wire! ’ Tom’s death, while instilling a sense of masculinity back to Tom’s character role, also gives us a sense of uncommon femininity in May reverting her to the underlying fact that she is a female. Throughout the drama, May is often shown to be the cold hearted, aggressive character yet Tom’s death leads her to act out in a more emotional, feminine way and expresses her sorrowed emotions. This is similar to Stanhope and Raleigh’s relationship in ‘Journey’s End’.Both are emotionally connected, and have been for a long time, yet the older character, Stanhope, treats Raleigh as both an outsider and a stranger for the majority of the play, speaking down to him and criticising him largely. Stanhope says in one instance ‘ D’you understand an order? Give me that letter! ’. In many ways, the relationship shared by Stanhope and Raleigh is similar to that of Tom and May; the older and more experienced character doubts the abilities and maturity of the younger, more innocent individual therefore limiting the care that is expressed between them.Just as with May, Stanhope openly expresses his emotions during the death of Raleigh, showing a return to the Stanhope that was described by Raleigh earlier in the play – a hero, an idol, who cared for him. ‘Stanhope gently takes his hand. ’ Stanhope expresses a great deal of care for Raleigh in his final moments of life and attempts to make his death as comfortable as possible. This seems to show appreciation for him as a person per-war as well as a brave solider. This is similar to how May expresses her sorrow for Tom’s death in ‘The Accrington Pals’.To conclude this essay, the gender of a person seems to alter the role they played during World War One. Men were expected to fight for their honour and country whereas women were expected to stay at home and support infants and households. Each role is an act of protection. Whether it was staying at home in Accrington, or fighting at the front in ‘Journeys End’, a place in society was inevitably determined by gend er. ‘Journeys End’ was written from the personal perspective of R. C. Sherriff, so is more likely to be based on his own experiences of the war.It is very likely that Sherriff witnessed the discussed gender roles and identities as part of the reality of war, adding to the credibility of the factual based play. His work seems to be heavily based on gender hegemonies apt of the Great War era giving extra depth and dimension to the truth of War. However one must not forget Peter Whelan wrote ‘The Accrington Pals’ when the war was over, therefore using information and experiences from historical evidence. Although this may be a more rounded opinion, in my opinion the real life experiences of R. C. Sherriff creates a far more credible and powerful piece of literature.

The first step to finding mass percent is to find the atomic mass of each element in the molecule.K3Fe(CN)6 is made up of potassium (K), iron (Fe), carbon (C) and nitrogen (N).Using the periodic table:Atomic mass of K: 39.10 g/molAtomic mass of Fe: 55.85 g/molAtomic mass of C: 12.01 g/molAtomic mass of N: 14.01 g/mol​​ Step 2: Find the mass combination of each element. The second step is to determine the total mass combination of each element. Each molecule of KFe(CN)6 contains 3 K, 1 Fe, 6 C and 6 N atoms. Multiply these numbers by the atomic mass to get each elements mass contribution.Mass contribution of K 3 x 39.10 117.30 g/molMass contribution of Fe 1 x 55.85 55.85 g/molMass contribution of C 6 x 12.01 72.06 g/molMass contribution of N 6 x 14.01 84.06 g/mol​ Step 3: Find the total molecular mass of the molecule. The molecular mass is the sum of the mass contributions of each element. Simply add each mass contribution together to find the total.Molecular mass of K3Fe(CN)6 117.30 g/mol 55.85 g/mol 72.06 g/mol 84.06 g/molMolecular mass of K3Fe(CN)6 329.27 g/mol​ Step 4: Find the mass percent composition of each element. To find the mass percent composition of an element, divide the mass contribution of the element by the total molecular mass. This number must then be multiplied by 100% to be expressed as a percent.Mass percent composition of K mass contribution of K/molecular mass of K3Fe(CN)6 x 100%Mass percent composition of K 117.30 g/mol/329.27 g/mol x 100%Mass percent composition of K 0.3562 x 100%Mass percent composition of K 35.62%Mass percent composition of Fe mass contribution of Fe/molecular mass of K3Fe(CN)6 x 100%Mass percent composition of Fe 55.85 g/mol/329.27 g/mol x 100%Mass percent composition of Fe 0.1696 x 100%Mass percent composition of Fe 16.96%Mass percent composition of C mass contribution of C/molecular mass of K3Fe(CN)6 x 100%Mass percent composition of C 72.06 g/mol/329.27 g/mol x 100%Mass percent composition of C 0.2188 x 100%Mass percent composition of C 21.88%Mass percent composition of N mass contribution of N/molecular mass of K3Fe(CN)6 x 100%Mass percent composition of N 84.06 g/mol/329.27 g/mol x 100%Mass percent composition of N 0.2553 x 100%Mass percent composition of N 25.53%​ The Answer K3Fe(CN)6 is 35.62% potassium, 16.96% iron, 21.88% carbon and 25.53% nitrogen.It is always a good idea to check your work.

Forensic speaker identification Essays

Forensic speaker identification Essays Forensic speaker identification Essay Forensic speaker identification Essay Introduction Forensic talker designation is the application of scientific discipline to work out the jobs related to designation of the unknown talker in condemnable probe. A voice is much more than merely a twine of words. Although grounds from DNA grabs the headlines, but the fact is that DNA ca nt speak. It ca nt be recorded planning, transporting out or squealing to a crime1. The voice of a individual can be successfully used as a biometric characteristic as it is good accepted by the users and can be easy recorded utilizing mikes and hardware of low costs2. It can supply an option, more unafraid agencies of allowing entry without any demand of retrieving a watchword, lock combination etc and therefore, interrupting all limitations of accessing a secured country utilizing keys, magnetic card or any other fallible device which can be easy stolen. In the present epoch, widely available installations of telephones, Mobiles and tape recording equipments consequences in the abuse of the device and therefore, doing them an efficient tool in committee of condemnable offenses such as snatch, extortion, blackmail menaces, obscene calls, anon. calls, torment calls, ransom calls, terrorist calls, lucifer repairing etc. The felons has seen the possibility for abuse of the assorted manners of communicating of voice, believing that he will stay incognito, and therefore, cipher would acknowledge him. It is fortuitously no longer true. The voice can place him and trap the offense on him3. Speaker designation is less complicated and leads to a more definite sentiment when the expert has to cover with the normal or ideal voice acknowledgment. The job arises when the instances of cloaked voice samples, affecting both inadvertent every bit good as attempted camouflage, comes for the intent of designation. There is another facet that makes the accomplishment of this end of talker designation a spot hard i.e. the instance of about similar sounding talkers, sharing the same sex, age and idiom. Address Address is the voice signifier of human communication4. Human existences express their thoughts, ideas and feelings orally to one another through a series of complex motions that alter and mold the basic tone created by voice into specific, decodable sounds5. Speech development is a gradual procedure that requires old ages of pattern. Communication is a procedure, a series of events leting the talker to show ideas and emotions and the hearer to understand them. Speech communicating begins as idea that is transformed into linguistic communication for expression6. : Speech signal is a multidimensional acoustic wave7 ( as shown in fig 1 ) , which conveys the information about the words or message being spoken, individuality of the talker, linguistic communication spoken, the presence and type of address pathologies, the physical and emotional province of the talker. The individual s address besides contains the characteristics that may uncover their geographical beginning, ethnicity or race, age, sex, instruction degree and spiritual orientation and background8, 9, 10. Often, worlds are able to pull out the individuality information when the address comes from a talker they are acquainted with. Address is a compelling biometric for several good known grounds and peculiarly because it is the lone 1 available mode in a big set of situations11 SPEECH MECHANISM AND ITS UNIQUENESS The mechanism of address is a really complex one and to set about analysis of any linguistic communication it is of import to understand the procedures that go to do up the message that a talker transmits and a hearer receives12. For production of any sound, there must be some perturbation in the air. Such perturbation in the address sound is provided by motion of certain variety meats of organic structure such as musculuss of thorax, vocal cords, lingua, lips etc. This perturbation in the signifier of sound moving ridges travels to the ear of the hearer, who interprets the moving ridge as sound. By the procedure of inspiration the air from the environment is drawn into the lungs, stored in the lungs for a short period of clip and eventually expelled from the lungs under force per unit area by the procedure of halitus. During halitus, air under force per unit area is sent from the lungs to the voice box. The map of the voice box, peculiarly that portion known as the vocal creases, is to put the molecules of this breath watercourse into vibration13 ( as shown in fig 2 ) . For sound to be produced, these molecules have to vibrate at a rate that falls within a peculiar scope. The procedure by which molecules of air are set into quiver is known as voice. The quiver form of molecules produced by voice is complex. It contains a broad scope of frequences and has a buzzing sound. This bombilation is moulded into address sounds by vocal piece of land. The vocal piece of land consists of the throat ( pharynx ) , unwritten pit and rhinal pit. The constellation, or form, of the vocal piece of land at a peculiar minute determines what address sound will be produced. The constellation of the vocal piece of land can be changed by motion of several constructions within it specifically, the lingua, lips, lower jaw and soft palate14. Representation of address mechanism For identical voice, the two persons should hold the indistinguishable vocal mechanism and indistinguishable coordination of their articulators, which is least likely. Hence the human voice is alone personal trait. SPEAKER RECOGNITION Speaker acknowledgment may be defined as any activity in which a address sample is attributed to a individual on the footing of its acoustic or perceptual properties15.The information content of a spoken vocalization are talker features, spoken phrase, emotions, extra noise, channel transmutations etc16.It can be divided into Speaker Identification and Speaker Verification. Speaker designation determines which registered talker provides a given vocalization from amongst a set of known talkers. The unknown talker is identified as the talker hose theoretical account best matches the input vocalization. Speaker confirmation accepts or rejects the individuality claim of a talker is the talker the individual they say they are17, 18, 19? In talker acknowledgment, you do nt do the designation by analyzing the linguistic communication used, by retrieving what the talker looks like or by any other agencies. This is sometimes used when a individual is non rather certain whether the procedure is that of confirmation or identification20. In a strategy for the mechanical acknowledgment of the talkers, it is desirable to utilize acoustic parametric quantities that are closely related to voice features that distinguish talkers. It involves choice of such parametric quantities which are which are motivated by known dealingss between the voice signal and vocal-tract forms and gestures21. In talker acknowledgment we differ between low-level and high-ranking information. High level-information is values like a idiom, an speech pattern, the speaking manner, the capable mode of context, phonetics, prosodic and lexical information22. These characteristics are presently merely recognized and analyzed by worlds. The Low-level characteristics are denoted by the information like cardinal frequence ( F0 ) , formant frequence, pitch, strength, beat, tone, spectral magnitude and bandwidths of an person s voice23. An ideal characteristic would: Have lower intraspeaker variableness and high interspeaker variableness Be robust against noise and deformation Occurs often and of course in address Be easy to mensurate from speech signal Difficult to mime Not be affected by talker s wellness or long term fluctuations in voice There are different ways to categorise the characteristics. From the point of view of their physical reading, we can split them into24: Short-run spectral characteristics -These characteristics, as the name suggests, are computed from the short frames of approximately 20 to 30 msecs in continuance. They are normally the forms of the resonance belongingss of the supralaryngeal vocal piece of land. Voice beginning characteristics -These characteristics characterize the glottal excitement signal of sonant sounds such as glottal pulse form and cardinal frequence, and it is sensible to presume that they carry speaker-specific information. Spectro-temporal characteristics -It is sensible to presume that the spectro temporal Signal inside informations such as formant passages and energy transitions contain utile speaker-specific information. Prosodic features Prosody refers to non-segmental facets of address, including syllable emphasis, modulation forms, talking rate and beat. One of import facet of inflection is that, unlike the traditional short-run spectral characteristics, it spans over long sections like syllables, words, and vocalizations and reflects differences in talking manner, linguistic communication background, sentence type and emotion of the talker. High degree characteristics -These characteristics attempt to capture conversation-level features of talkers, such as characteristic usage of words ( uh-huh , you know , oh yeah , etc. ) . Other characteristics are the idiom of any linguistic communication used in the conversation by the talker, speech pattern of the talker and the manner of speech production. DISGUISED SPEECH Any type of change, deformation or divergence from the normal address, irrespective of the cause, is defined as the address camouflage. Disguise can take many signifiers, and can be really detrimental to both ballad every bit good as to proficient talker identification25.The condemnable frequently disguises his or her voice. The consequence of the camouflage is that, the acoustic characteristics of the condemnable example, is altered to go less similar to the acoustic characteristics of the existent felon s undisguised vocalizations. There tended to be two types of research. One type was non-electronic and attempted to mensurate the ability of non-expert worlds to place other worlds who were masking their voice in a assortment of ways. The 2nd type was electronic, frequently affecting speech spectrographs, or alleged voiceprints 26. The inquiry of voice camouflage sensing appears as cardinal in forensic applications. Different sorts of attacks provide important consequences of favoritism. A complementary survey based on formant and automatic analysis could be fused to increase the acknowledgment rate27. MOTIVATION IN STUDYING DISGUISED SPEECH28 By and large, the adept faces two types of challenges while analyzing the questioned. First, cloaked voice is frequently used in the commitment of a offense where the felon has the fright of being caught. Often, it is necessary to place or verify a suspect based on the cloaked voice. Some agencies is needed to: Determine that a voice has been disguised on a voice recording, Determine the method of camouflage Perform computing machine talker designation despite the camouflage. The 2nd challenge is that the talker designation basically is incapable of accurately finding the individuality of a talker when a trial sample of his cloaked address is compared to a mention based on his normal speech production manner. To day of the month, and to the best of our cognition, the above statement remains true. One end of forensic talker acknowledgment is to set about research to change by reversal that state of affairs, at least for a big and utile subset of camouflage types. TYPES OF DISGUISE Disguised address can be of two types: Non- deliberate or inadvertent disguise- This signifier of voice camouflage involves changes that consequence from some nonvoluntary province of the person. The instances of inadvertent camouflage involve the impermanent alteration in individual s address due to alter in physical province like due to masticating, eating and illness or emotional province of individual like emphasis, choler, fright, jitteriness, sunniness, surprise, sadness etc. Research has been done for developing robust and precise automatic talker confirmation system based on these talker based fluctuation in features29. Deliberate or attempted disguise- The samples of attempted camouflage are often encountered in the instances of anon. calls, ransom calls and endangering calls where the talker makes a calculated attempt to alter their voice by altering its phonic, phonemic and prosodic characteristics, in order to conceal their individuality due to the fright of being caught. TECHNIQUES USED FOR SPEAKER RECOGNITION In this epoch of telephones, wireless and tape recording equipment communications, the human voice may frequently turn out to be valuable grounds for tie ining an person with condemnable act. The telephoned bomb menace, obscene calls or tape recorded ransom messages have become frequent plenty happenings to justify the involvement of jurisprudence enforcement functionaries in scientific techniques capable of transforming the voice into a signifier suitable for personal identification31. Speaker designation is to find who the talker of the given vocalization is. To make so it is necessary to cognize a great trade about that individual s address feature ( a rare happening ) or to be able to fit the voices of the unknown speaker to one from the group of suspects. Assorted methodological analysiss for nearing the job of talker designation have been proposed. For designation intent, different good recognized criterion techniques will be used for keeping the cogency of the work done and the pick will be as per the demand: 1 ) Listener method or Auditory analysis- The voice of a individual is as easy distinguishable by the ear, as face by the oculus. This method of talker acknowledgment by listening is the oldest amongst all. In this state of affairs a individual attempts to acknowledge a voice by its familiarity32. The extraordinary ability of worlds to acknowledge many familiar people by their voices is exceeding both in truth and adaptability33. In this method, the determination of similarity and unsimilarities is taken by human experts after hearing of address samples. One method is of perennial hearing of the available audio files by a group of experts looking for similarities in lingual, phonic and acoustic characteristics. The different vocalizations of the talkers are segregated in regard of each talker by manner of perennial hearing of recorded conversation. The unintegrated conversations of each talker are repeatedly heard to place lingual characteristics and phonic characteristics like articulation rate, flow of address, grade of vo wels and harmonic formation, beat, dramatic clip, pauses etc. The hint words are selected from both questioned and specimen samples of the talker and are so used for instrumental analysis. Human hearers are robust talker recognizers when presented with the debauched address. Listener public presentation is a map of acoustic variables such as, the signal to resound ratio, address bandwidth, the sum of speech stuff, deformations in the address signals introduced by address cryptography, transmittal systems, etc. This is owing to the fact that there are beginnings of cognition that contribute in assorted ways to speaker acknowledgment ; supplying weak, moderate and high know aparting power. Auditory talker acknowledgment has long been used and accepted in forensics as portion of the testimony of a victim or informant. Prior to the innovations of the telephone and sound recording equipments, it could be the cardinal grounds on behalf of which a suspected person could be identified or excluded from an offense committed in the dark or when a victim has been blindfolded34. However, with any human determination procedure, it is stressed that the hearer method leads to a subjec tive determination. However, this method is still used in some states for forensic talker designation. 2 ) Instrumental analysis or Spectrographic method- The spectrographic method for talker acknowledgment makes usage of an instrument that converts the address signals into a ocular show. Today voice analysis has matured into a sophisticated designation technique, utilizing the latest engineering scientific discipline has to offer. Both aural and spectrographic analyses are combined to organize the decision about the individuality of voice in question35. In 1941, an electro mechanical acoustic spectrograph was developed by Dr. Raleph Potter, Bell Telephone Laboratory, with an thought to change over sounds into pictures36. A sound spectrograph is an instrument which is able to give a lasting record of altering energy-frequency distribution throughout the clip of a address wave37, ( as shown in fig 3 and fig 4 ) . Spectrograms are ocular representations of the speech signal ; they convey information about the message by the talker every bit good as about the talker himself. In this method, the sentiment about similarities or unsimilarities between two samples will be taken on the footing of their phonic and acoustic elements such as, frequences, amplitude, plosive continuance, voiceless signals at different places etc. The sound spectrograph is more normally known as the Voiceprint analyzer. Voice forms are transformed into ocular forms on a graph that moves through an instrument at a controlled velocity, and forms drawn on the paper as it moves. By analyzing the charts, you can compare a tape of an person s normal address form with a tape of the same individual being questioned about his or her engagem ent in some type of offense or other misbehaviour38. These voiceprints may be an of import in assisting the jurisprudence enforcement bureaus in placing the felons. Much like fingerprints, voiceprint designation uses the alone characteristics in the spectrographic feelings of people s utterances39. In the classical parallel spectrograph a magnetic tape recording equipment and playback unit is used to treat the sounds into electronic signals. These signals are so sent through a variable electronic bandpass filter, which selects a frequence set that is to be analysed, before a stylus measures its energy and records the consequences on electrical sensitive paper. The paper is mounted on a membranophone, which is revolving during playback in order to plot the clip fluctuations in the signal. When the whole length of the address sample in analysed at a specific frequence set, the set of the filter and the place of the stylus are correspondingly altered. The tape is so played once more in order to analyze a new portion of the frequence spectrum. This procedure is repeated over once more until the full coveted frequence scope is analysed. In each spectrograph, the horizontal dimension is clip, the perpendicular dimension represents frequence and the darkness represents the strength on the compaction scale40.The differences in amplitude values are shown in a Grey scaling where black represents the most intense and white the least intense wave form constituents. However since 1962, it was considered as a fool- cogent evidence method of personal designation, voice designation by spectrographic analysis, the voiceprint technique has been in a legal oblivion. But the recent developments in both scientific discipline and the jurisprudence, nevertheless, indicate that despite ab initio inauspicious scientific and judicial reaction, spectrographic voice designation is possibly coming of legal age41. 3 ) Computerized approach- This is a semi automatic attack for acknowledgment of address samples which involves three phases: Feature Extraction Feature Comparison Categorization In this method the parametric quantities of the signals are extracted by agencies of spectrum analyser and acknowledgment is made by agencies of computing machine system on the footing of stored informations in regard of controlled samples of the talkers. However it is observed that the mistake rates of machines are frequently more than an order of magnitude greater than those of worlds, as machine public presentation degrades below that of worlds in noise, with channel variableness, and for self-generated speech42. 4 ) Modern technique utilizing a package: BATVOX 3.043- BATVOX 3.0 is an automatic talker acknowledgment application designed to let the biometric designation of talkers in an probe comparing voice theoretical accounts to a set of sounds added in the system. The audio files entered in BATVOX 3.0 have to carry through certain conditions: BATVOX 3.0 accepts audio files in the undermentioned format: .wav files with additive PCM cryptography, trying frequence 8 KHz, 16-bit declaration and glandular fever. Manages audio files of at least 7 seconds of net address. Manages audio files whose signal to resound ratio is more than 10dBs The trial and the preparation audio files should possess the voice of the talkers sharing the same sex, same linguistic communication and have same channel features LIMITATIONS OF SPEAKER IDENTIFICATION44 Short continuance samples should be analysed decently The dissimilar linguistic communication in questioned and specimen are hard to analyse Emotion Variability in questioned and specimen samples45 Misspoken or misread prompted phrases Ill recorded/noisy samples are hard to analyze46 Insufficient figure of comparable words Disguise in address samples poses a job in talker acknowledgment and/or the grade of camouflage is decided by the expert Extreme emotional provinces ( e.g. emphasis or duress ) 47,48 Change in physical province of the talker ( e.g. feeding, consequence of ethyl alcohol, etc ) 49 The attitude of the how the address is said by the talker Channel mismatch or mismatch in entering conditions ( e.g. utilizing different mikes for registration and confirmation ) 50 Different pronunciation velocity of the trial informations compared with the preparation informations. Illness 51,52 Aging ( the vocal piece of land can float off from theoretical accounts with age ) 53,54 ACCURACY IN SPEAKER RECOGNITION In order to acquire accurate consequences from talker acknowledgment, one must give more accent on following factors: The minimal continuance of the gathered samples should be of 60 seconds Conditionss under which the voice samples are recorded should possess less noise or the signal to resound ratio of the samples should be greater The features of the instruments used The accomplishment of the tester doing judgement Examiners knowledge about the instance Examiners knowledge about the linguistic communication in question55 Properties of the voice involved Delay in scrutiny of samples56 The linguistic communication of the questioned and controlled samples should be similar The expert should be competent plenty to cover with the instances affecting cloaked address samples. CRITERIA FOR IDENTIFICATION A hearer may acknowledge a voice even without seeing the talker. There are cues in voice and address behavior, which are single and therefore do it possible to acknowledge the familiar voices57. A individual s mental ability to command his vocal piece of land musculuss during vocalization is learned during his childhood. These wonts affect the scope of sound that may be efficaciously produced by an person. The scope of sounds is the subset of the set of possible sounds that an person could make with his or her personal vocal piece of land. It is non easy for an single to alter voluntarily these physical characteristics58. The address moving ridge is the response of the vocal piece of land filter system to one or more sound beginning. Speech moving ridge may be unambiguously specified in footings of beginning and filter characteristics59. Datas obtained from measurings of the acoustic belongingss of human voices are really different from Deoxyribonucleic acid profiles. Acoustic inform ations are uninterrupted non distinct and the talker neer says the same thing, precisely the same manner twice. The strength of grounds from a forensic voice comparing can non be expressed as a lucifer chance and must be expressed in signifier of a full likeliness ratio60. It is observed that really dependable determinations can be made by trained professional testers when samples are obtained in the mode described. The surveies produced strong grounds that even really good mimics can non double an- other s address patterns61. The standards of designation of address samples utilizing different techniques are discussed as follows: Auditory analysis- In this method, the designation is done on the footing of following voice characteristics- Quality of speech sample- Synthetic address can be compared and evaluated with regard to intelligibility, naturalness, and suitableness for used application62. Pronunciation, Accent, Speech sounds like vowels and consonants, stop consonants, spirants, nasal and pharynx sounds and matching consequence, Grammar, Stress, Syllable emphasis, Intonation, Rhythm, Fluency, tempo, Phrasing and Blending63. Each individual possesses a alone voice quality which depend on figure of anatomical characteristics, such as, dimension of unwritten piece of land, throat, rhinal pit, form and size of lingua and lips, place of dentition, tissue denseness etc. Linguistic features- Linguistics is the scientific survey of natural linguistic communication. These characteristics involves, the fashionable feeling of address, bringing of address ( the manner in which the address is delivered i.e. , Manuscript, Memorized, Impromptu, and Extemporaneous64 ) , Phonation ( the procedure by which the vocal creases produce certain sounds through quasi-periodic quiver or any oscillating province of any portion of voice box that modifies the airstream, of which voicing is one example65 ) . Articulatory speech- This is a type of address produced by motion or articulation of the articulators. This involves, flow of address ( depends upon the eloquence of the speaker66 ) , plosive formation ( First, a complete closing of the transition of air at the same point in the vocal piece of land, so the remotion of the closing, doing a sudden release of the out of use air with some explosive noise ) , nasality ( Nasal consonants have a uninterrupted full closing at some point in the unwritten pit. Since the veil is set in the low place, opening the velopharyngeal port, air is let out through the rhinal pit ) . Prosodic analysis- It involves the modulation form, moral force of volume ( kineticss refers to the volume of a sound or note and volume is the strength of esthesis received through the ear ) , speech rate ( comparative timing of different address events in spoken vocalizations ) , speech fluctuations, striking clip characteristics, intermissions ( number/length/pattern ) . Voice impairment- Speech or linguistic communication damage ( SLI ) means a communicating upset, such as stuttering, impaired articulation, linguistic communication damage, or a voice damage, that adversely affects a individual s educational public presentation. Speech and linguistic communication upsets refer to jobs in communicating and related countries such as unwritten motor map. These holds and upsets range from simple sound permutations to the inability to understand or utilize linguistic communication or utilize the oral-motor mechanism for functional address and eating. Some causes of address and linguistic communication upsets include hearing loss, neurological upsets, encephalon hurt, mental deceleration, drug maltreatment, physical damages such as cleft lip or roof of the mouth, and vocal maltreatment or abuse. Frequently, nevertheless, the cause is unknown. Temporal measurements- The temporal belongingss of address play an of import function in lingual contrast. Address can be said to be comprised of three chief temporal characteristics based on dominant fluctuation rates ; envelope, cyclicity and all right construction. Each characteristic has distinct acoustic manifestations, auditory and perceptual correlatives and functions in lingual contrasts67. These measurings involves phonation-time ( P/T ) ratio, address clip ( S/T ) rate, address explosion ( its number/length/patterns ) . Spectrographic analysis- The spectrograph is an instrument used to analyze the complex wave forms of sound and their changes in clip. This is done through spectrographs, which are in writing shows of the amplitude as a map of both frequence and time68. In this method, the hint words are selected from the questioned and the specimen samples on the footing of audile analysis. These are so selected for voice spectrographic analysis. A trained tester may be able to give an sentiment about the similarity between the two samples on the footing of features like: Cardinal frequency- It is the frequence of quiver of vocal cord produced during the rapid gap and shutting of vocal cord69, ( as shown in fig 5 ) . The cardinal frequence of a periodic signal is an opposite of period length. The period, in bend, is the smallest reiterating unit of a signal70. In voice spectrograph, horizontal distance between perpendicular striations is an indicant of cardinal frequence. It besides includes the pitch of voice i.e. , the rate of quiver of vocal cords. Software, BATVOX 3.0- The working of this package depends upon the undermentioned elements43: Case- It is the depository of audio files, theoretical accounts and computations portion of the same probe or forensic instance. Audio file- this is the first component to come in into the system in order to construct the theoretical accounts and calculate some biometric computations. The audio files in BATVOX can chiefly classified in two types Trial sound: Unknown sound file used to be compared to a fishy theoretical account in order to happen it out if both belongs to the same talker Training sound: sound file recorded from the known talker, used to make a voice theoretical account which can be compared with the trial sound files. Model- A theoretical account generated from the sound files is the representation of features of the talker s voice. Training of a model- A biometric procedure which extracts the features of the voice from the sound samples and therefore, generates a theoretical account. Session- Group of computations gathered together because of some common facets harmonizing to the standards of the user. The computations included in a session can be designation and a LR computation. Identification- The aim of the talker designation is to sort a voice whose beginning is non known. Likelihood ratio ( LR ) It is a relationship of chances. First, we have the likeliness that the trial belongs to a suspect and secondly, the trial does non belong to the suspect. One of the differences between the LR and designation is the manner of showing consequences. Normalization- It is the procedure of rectifying the effects that the deficiency of alliance has on statistical marking. This deficiency of alliance is caused by the heterogenous nature of the sound system. Reference population- These types of samples are fundamentally required for the standardization of the instrument. For a proper choice of the mention population, the features of the population should fit the features of the disputed talker. These features include the sex of the talker, channel type, net spoken length and language75.

The Promotion of Unhealthy Habits through Smoking Essay

The Promotion of Unhealthy Habits through Smoking - Essay Example This essay "The Promotion of Unhealthy Habits through Smoking" outlines the negative effect of the advertising, its targets and the most influenced age group. Till as late as the 1970s tobacco companies had an almost unobstructed ride with their freewheeling advertisements. However, as more and more irrefutable scientific evidence pointed towards smoking-related health hazards, governments of more advanced nations and various other social and medical groups took up cudgels against irresponsible cigarette advertisements that could mislead people. In the United States such resistance culminated in the Master Settlement Act (MSA) signed on November 1998 between 46 states and five territories and he major tobacco companies viz. Phillip Morris Companies (now known as Altria), RJ Reynolds Tobacco, Lorillard Tobacco, and Brown and Williamson. The MSA came into effect in 1999 and curbed outdoor cigarette advertising, transit advertising, cigarette-related cartoon characters, product placemen t in the media and tobacco merchandizing (Krugman et al, 2006, pp. 197). Simultaneously, it had been made mandatory that all tobacco products carry health hazard warnings, and even more stringent laws have been enacted in states such as California to ban tobacco advertisements in youth magazines and sale of tobacco to young people. In spite of all such anti-smoking measures, tobacco companies still managed to come up with novel ways of circumventing the law and rules and use advertisements to promote sales.

Criminal Litigation. Case Management Essay Example | Topics and Well Written Essays - 4000 words

Criminal Litigation. Case Management - Essay Example The inclusion of expert evidence in civil and trial has increased remarkably to encompass, for example, modern and innovative scientific procedures and related assessment reports. This paper critically examines how courts have influenced expert evidence at trial. Common law traditions require that expert witnesses are only sought with the permission of the court and that the principal obligation of the experts is to remain impartial to the court during the course of their submissions. The obligations and conduct of expert witnesses are well stated in both the Practice Direction 35 and the Civil Procedure Rules (CPR) Part 35, with CPR Part 35.3 specifically indicating that: experts are duty-bound to assist the judicial process on the issues within the scope of their respective professions. The obligation surpasses any duty to the party from whom such a professional has received briefing or who is responsible for their earnings (Gans 353). In addition, Practice Direction 35.2 also indicates that expert evidence should be the impartial outcome of the expert who is free from the duress caused by the long-drawn and challenging litigation procedures. However, the fact that there are two different categories of experts raises the controversy of impartiality at trial. As Sonenshein and Fitzpatrick (14) noted, an expert with clear directions to provide evidence at trial and another expert whose evidence is basically advisory may have clearly delineated mandates. However, the provisions of CPR Part 35 and Practice Direction 35 normally apply in factual evidence provision rather than giving opinion evidence at trial. Expert evidence in court processes is regarded as having the potential to shade more light on issues which are beyond the understanding of conventional fact-finding process. However, members of the court are sometimes ill-equipped to tell whether expert
