In The Odyssey by Homer, Odysseus displays being a strong leader through his responsibility, courage, and brilliance while leading his warriors through calm and harsh times. Odysseus faces hard decisions at times, but his leadership never wavers. In Greek mythology, a strong leader defines as being respected by those he leads, he has logical thinking, and he shows bright ideas. In the beginning of the story, Odysseus demonstrates his responsible character when making the heart-wrenching decision between his family or war. He has to decide between leaving his wife and newborn and possibly never seeing them again, or not fighting for his hometown Ithaca. This shows when Odysseus watches his native land disappear, Mine is a rugged land but good for raising sons, and I myself, I know no sweeter sight on earth than a mans own native country (Homer 212). The passage explains that it is hard to watch his land go, but it is also saying bye to raising his family and his self as a person. Don’t waste time! Our writers will create an original "Leadership in The Odyssey" essay for you Create order Also, it is hard for Odysseus because his town looks up to him for being the leader of their island. Odysseus puts his personal life behind him and makes the decision to fight for his village. This decision shows that his responsibility of being a leader takes priority over his own life. He gives up the place of home and devotes his life towards warfare. Odysseus explains the ideal leader has to be responsible and put his life on the line to lead his warriors. Time and time again Odysseus shows responsibility when he is figuring out a way to get back to Ithaca, so he takes it upon himself to go to Aeolus for the bag of wind. This is just one of many responsible instances when Odysseus puts himself in danger to save his warriors. Responsibility is what grows upon Odysseus throughout the book, and it is what makes him be the great leader he is. Continuing, Odysseus represents his courageous quality not only during the Trojan war but many times throughout the novel. For example, when he climbs up the steep mountain to save his men, leaving the ship and shore, I headed inland, chambering up through hushed, entrancing glades untilHermes god of the golden wand crossed my path.Where are you going now, my unlucky friend, trekking over the hills along in an unfamiliar country? (Homer 239). This example demonstrates that the journey up the mountain was a great struggle for Odysseus, but he never gave up because he is going to save his soldiers. It also exemplifies his unselfishness as he could have left and continued onto Ithaca, but decides to stay and save his men. His courage also shows when Odysseus loses all his soldiers to the sea monster, but he must survive in the ocean by himself. He thought he was not going to survive but never gave up because he wants to return to Ithaca. Continuing throughout the novel, Odysseus shows h is courageous skills to protect his men and himself. Odysseuss brilliant mind shines when having to go through hard tasks. It is what drives his decisions throughout the book, and it is what makes him an especially great leader. An excellent example of this is when he comes up with the idea of hiding in the horse and then attacking the Trojans. If it werent for this idea, he possibly would not have defeated the Trojans. Throughout the journey with his men, Odysseus carries them through tough situations, using his great ideas to help them out. Another example is when the giant trapped him and his men in a cave, but Odysseus came up with the idea of stabbing him in the eye to move the rock covering the door, So we seized our stake with its fiery too and bored it round and round in the giants eye till blood came boiling up (Homer 223). As stated earlier, the quality of thinking logically is one that defines a good leader in Greek mythology. Odysseuss brilliant mind helps him achieve this level of greatness. In conclusion, Odysseus responsibility, courage, and brilliance shows through significant events in the novel and eventually lead them to victory. It makes him be an incredible leader to his men, like saving them, guiding them, and explaining his unique ideas to the men. Odysseus never gave up on his crew, even when they werent the most brilliant. All in all, it is for Odysseus responsibility, courage, and brilliance to make him be the leader that brought a small but mighty army to victory.

The Character of Gertrude in Shakespeare’s Hamlet Essay

The character of Gertrude in Shakespeare’s tragedy, Hamlet, is not a woman for emulation by others. She is too human, and not very intelligent. Let’s consider her in this essay. Mary Bradford-Whiting, in her article â€Å"Mothers in Shakespeare† compares the mother of Juliet to the mother of Hamlet: Juliet has a mother, to whose heart of stone she appeals in vain: . . . O, sweet my mother, cast me not away! [Romeo and Juliet, III.v.198] Hamlet has a mother, each remembrance of whom is a pang to his distressed mind, and of whose conduct he can only say: Let me not think on’t. Frailty, thy name is woman!

Gertrude was seduced by â€Å"that incestuous, that adulterate beast, / With witchcraft of his wit, with traitorous gifts† – Claudius himself – prior to his brother’s passing. â€Å"So lust, though to a radiant angel linkd, / Will sate itself in a celestial bed,/And prey on garbage.† This revelation shows Gertrude’s complex temperament and motivation and renders her much more rounded in the dramatist’s development of her (Abrams 33). The ghost asks the protagonist to disregard revenge on Gertrude: â€Å"Taint not thy mind, nor let thy soul contrive / Against thy mother aught,† and to leave her â€Å"to those thorns that in her bosom lodge, / To prick and sting her.† Gertrude has a contrasting character in the person of Ophelia, who is the picture of purity and innocence. Ophelia obeys her very morally and socially conservative father, Polonius, in every detail, even to the extent of giving him her love-letters from Hamlet; unlike Gertrude, who brazenly violates her marriage vow, then breaks social conventions in marrying within a month of her first husband’s funeral, and incestuously marrying her husband’s brother.

In Harper Lee’s book, To Kill a Mockingbird, which is based upon a true story, Tom Robinson, a man accused of rape, Scout Finch, a tomboy and lawyer’s daughter that observes occurrences in Maycomb, resists racist comments, and does not always understand things, who is also the narrator of the publication, both in a childish fashion and in an adult like fashion, and Atticus, a lawyer who is intelligent, respected and respecting, and defends Tom Robinson in his time†¦show more content†¦Harper Lee reveals the book To Kill a Mockingbird as a work that portrays the past events and matters of racism, poverty, and, in some cases, domestic violence in a scene loca ted in the south, in this instance, an imaginary town called Maycomb involving the Ewells, during the Great Depression. In Harper Lee’s book, To Kill a Mockingbird, racism in Maycomb is a common theme. Atticus and Tom Robinson are frequent racism symbols mentioned in the novel. This deeply influences the actions of these characters in that Atticus defends Tom Robinson in a case because no one else is up for the challenge. No one else wants to defend a black man who is accused by a reckless white family, the Ewells. Atticus feels that he has no other choice than to be Tom Robinson’s lawyer and defend his case. He has several justifiable reasons to do so. â€Å"The main one is, if I didn’t I couldn’t hold my head up in town, I couldn’t represent this county in the legislature, I couldn’t even tell you or Jem not to do something again† (Lee 100). This was the essential reason Atticus takes on the case, and it affected him personally. For one, he feels that without defending Tom Robinson and his case, it would be wrong and he would not be able to order Jem and Scout around. Additionally, no one else was going to

Cathedral By Raymond Carver Summary - 1773 Words

Summary â€Å"Cathedral†, a short story by Raymond Carver, centers around a blind man’s visit to a couple’s home. In the beginning, Carver elaborates a bit on who the blind is and how he stumbled into the lives of the two characters. Early in the women’s life, she was married to an Air Force officer. While he was away at his school or training, she became quite lonely and sought employment. She began working as a blind man named Robert’s companion in which she read books, journals, and articles to him as well as just talking with him and keeping him company. They developed a very good friendship, almost too good, however shortly after her husband’s return, she moved away, causing her to have to leave her job also. However, despite leaving her†¦show more content†¦He had an uneasy feeling about Robert staying in their home, but his wife had already told Robert he could and begged him to help make him feel comfortable so of course he a llowed it. The wife picked up Robert from the station and upon their return, they ate dinner, talked, and watched TV. The wife fell asleep on the couch resulting in Robert and the husband watching television and drawing. They began to bond over discussing religion and drawing cathedrals. Robert told him to draw with his eyes closed and they both got lost in the process of drawing. Connections From my perspective, the story connects to the real world through its similarities to some of today’s modern relationships. It was evident that the couple struggled with lack of an open mind, trust issues, and possessiveness, all of which tend to pop up in a lot of today’s relationships. In the beginning of the story it was made clear that the husband did not have an open mind. He knew his wife had offered up their home to him, but he did not want him there because he was blind. The idea of being blind and blind people in general bothered him. He compared real blind people to those he had seen portrayed on TV as slow and strange. While he did not have an open mind about the blind, I believe he could’ve also been against it because it was a male friend whom his wife shared so much history with.

Numerical Analysis of Soil-Structure Interaction at Seismic Fault Pulses Free Essays

string(197) " types of dirt media with a broad scope of shear–wave speed \(Volt\) were considered to cover soft to really heavy dirt in conformity with site categorization introduced in ASCE7–10 \[ 11 \] \." Numeric Analysis of Soil-Structure Interaction at Seismic Fault Pulses Abstraction—Numeric analysis of soil–structure systems at seismal mistake pulsations has investigated. Vibration transmissibility of the soil–structure interaction has analysed for super-structures with different aspect ratios positioned on assorted dirt types and different foundations have studied. Soil construction interaction with geometric nonlinearity has been considered with forward directionality and fling measure types of mathematical seismal mistake pulsations. We will write a custom essay sample on Numerical Analysis of Soil-Structure Interaction at Seismic Fault Pulses or any similar topic only for you Order Now It has been analyzed that nonlinear SSI is tend to magnify the acceleration responses when subjected to low frequence incident pulsations below normalized threshold frequences. These thresholds associate with dirt categorization, so that different dirt type has assorted shear moving ridge speed. With increased shear wave speed of the implicit in dirt makes the threshold frequence additions. Keywords—Nonlinear soil–structure interaction, response analysis, seismal mistake, land daze, swaying isolation. Introduction SHOCK and quiver isolation reduces the excitement transmitted to systems necessitating protection. An illustration is the interpolation of isolators between equipment and foundations back uping the equipment. The isolators act to cut down effects of support gesture on the equipment and to cut down effects of force transmitted by the equipment to the supporting construction. Isolators act by debaring and hive awaying energy at resonating frequences of the isolation system, thereby diminishing force degrees transmitted at higher frequences. The dampers act by dispersing energy to cut down the elaboration of forces that occur at resonance [ 1 ] . The chief thought in basal isolation is to cut down the seismal responses by infixing low–stiffness, high–damping constituents between the foundation and the construction [ 2 ] . This manner, the natural period and damping of the construction will be increased, which can cut down the responses of the superstructure, particularly i nter–story impetuss and floor accelerations [ 3 ] . Alternatively, base supplantings in those systems, particularly under near–fault land gestures, are increased [ 4 ] . The first concerns about this issue were arisen after 1992 Landers and so 1994 Northridge temblors, where long–period pulse–type land gestures were observed in near–fault records. Evidence show that temblor records in near–field parts may hold big energy in low frequences and can do drastic responses in base stray constructions [ 5 ] . Past surveies in the literature reveal that nonlinear soil– construction interaction ( SSI ) including foundation upheaval and dirt output can exhibit basal isolating effects due to hysteretic damping of the implicit in dirt. These effects can be important during strong land gestures when the superstructure is mounted on a shallow foundation with sufficiently low inactive perpendicular burden bearing safety factor [ 6 ] . On the other m anus, geometry of the superstructure should besides enable the swaying gestures of the foundation to emerge as a singular manner of quiver in seismal public presentation of the soil–structure system. In such status, the so–called inverted–pendulum constructions [ 7 ] can profit from energy absorbing capacity of the implicit in dirt viz. swaying isolation. This context motivated Koh and Hsiung [ 8 ] , [ 9 ] to analyze base isolation benefits of 3D rocking and upheaval. In their surveies, three–dimensional cylindrical stiff block rested on a Winkler foundation of independent springs and dashpots were examined. They compared response of the theoretical account under earthquake–like excitements when the foundation was allowed to elate versus no–uplift status. It was concluded that curtailing upheaval can present higher emphasiss and accelerations inside the construction. The purpose of this paper is shock response analysis of the soil– co nstruction systems induced by near–fault pulsations. Vibration transmissibility of the soil–structure systems is evaluated utilizing daze response spectra ( SRS ) . An in–depth parametric survey is conducted. Medium–to–high rise edifices with different aspect ratios every bit good as foundations with different safety factors located on different dirt types are studied. Two types of near–fault land dazes with different pulsation periods every bit good as pulse amplitudes are selected as input excitement. Linear versus nonlinear SSI status are considered instead and the corresponding consequences are compared. II. N UMERICAL MODEL The soil–structure system modeled in this survey consists of multi–story constructing constructions based on surface mat foundation located on dirt medium. Numeric theoretical account subjected to near–fault land dazes is schematically illustrated in Fig. 1. A. Superstructure Shear edifice theoretical accounts are most normally used in research surveies on seismically isolated edifices. To this purpose, a generic simplified theoretical account is created to stand for a category of structural systems with a given natural period and distribution of stiffness over the height [ 10 ] . In this survey, the superstructure is a 3D shear constructing habitue in program and height to avoid the effects of geometrical dissymmetry. Requirements for including near–field effects are considered harmonizing to ASCE7–10 [ 11 ] . Dead and unrecorded tonss are assumed 600 and 200kg/m2, severally. The narrative tallness of 3.0mand figure of narratives equal to 10, 15, and 20 are selected in order to stand for medium–to–high–rise edifices that can rationally hold shallow foundations on different types of dirt medium. First–mode natural periods of fixed–base construction are 1.0, 1.5, and 2.0sfor 10– , 15– , and 20à ¢â‚¬â€œstory edifices, severally. These natural periods are consistent with approximative cardinal period expressions introduced in ASCE7–10. The analyses have been performed utilizing OpenSEES package [ 12 ] . Rayleigh theoretical account with muffling ratio equal to 5 % of critical damping is assigned to the superstructure. In this instance, superstructure elements are assumed with no ductileness and P–Delta geometrical nonlinearity is included. FIG 1 B. Interacting System The interacting system called infrastructure consists of soil– foundation ensemble which induces base–isolating effects to the construction. The foundation is a square mat with thickness of 1.0, 1.5, and 2.0mfor 10– , 15– , and 20–story edifices, severally. Brick elements are used to pattern the foundation. Dimensions of the foundation program were designed harmonizing to perpendicular burden bearing capacity of dirt medium. Therefore, different foundation program dimensions are calculated sing to different dirt types every bit good as different safety factors. The foundation is assumed to be inflexible and no embedment is considered in this survey. In order to see dirt effects, four types of dirt media with a broad scope of shear–wave speed (Volt) were considered to cover soft to really heavy dirt in conformity with site categorization introduced in ASCE7–10 [ 11 ] . The dirt is considered as a homogeneous half–space medium and is non modeled straight in this survey. Simplified theoretical accounts are used to enforce substructure effects including dirt flexibleness, radiation damping, tenseness cut–off, and dirt output on the foundation. The horizontal ( sway ) electric resistances can be straight obtained utilizing Cone theoretical account expressions [ 13 ] . However, swaying and perpendicular electric resistances, because of part of foundation upheaval and dirt output nonlinear effects, could non be straight calculated utilizing lumped theoretical account in perpendicular and rocking waies. In perpendicular and swaying waies, the foundation country is discretized over a sufficient figure of nodes. The discretization of foundation program country has been done in conformity with so–called subdisk method recommended by Wolf [ 14 ] to cipher perpendicular and swaying dynamic electric resistance of dirt. In order to allow the foundation upheaval and dirt output phenomena contribute in finite component mold of soil–structure system the perpendicular nonlinear elastic–perfectly fictile spread stuff is assigned to the perpendicular contact elements. FIG 2 III. MATHEMATICAL NEAR–FAULT PULSES Idealized pulsations, used in this survey, are described by sinusoidal maps proposed by Sasani and Bertero every bit good as Kalkan and Kunnath that represent fling measure and frontward directionality type of land gestures [ 15 ] , [ 16 ] . The mathematical preparations of the acceleration clip history of fling–step and forward–directivity pulsations are presented in ( 1 ) , and ( 2 ) , severally.

In this research, pulse–to–fixed–base construction period ratio (ThymineT ) is assumed to fall within 0.5 to 2.5. Within this scope, existent near–field records can be replaced by idealised pulsations and outstanding belongingss of structural response are captured with sensible estimate [ 17 ] , [ 18 ] . Furthermore, pulse amplitude matching to different excitement degrees varies from moderate to really strong land gestures in this survey. For this intent, peak land speed ( PGV ) varies from 20 to 220cm/sto stand for moderate to really strong land gestures, severally. In this survey, unidirectional excitement is exerted to th e base when the simplified pulse theoretical accounts of fling measure and forward directionality are used. IV. PARAMETRIC STUDY It is good known that the response of soil–structure system depends on geometric and dynamic belongingss of the construction and the beneath dirt. These effects can be incorporated into the studied theoretical account by the undermentioned non–dimensional parametric quantities [ 19 ] , [ 20 ] : img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/1571341.003.png"/ where a0,hole,Hydrogen,Volt,Strontium, andBacillusbase for non– dimensional frequence, round frequence of the fixed–base construction, superstructure tallness, shear–wave speed of dirt, slenderness ratio, and breadth of the superstructure, in the same order. Non–dimensional frequence parametric quantity,a0, is introduced as an index for the structure–to–soil stiffness ratio. In this survey, this parametric quantity is assumed 0.25, 0.5, 1, and 2 to cover different degrees of dirt flexibleness. Harmonizing to ( 1 ) , the a0 peers to 0.25, 0.5, 1.0, and 2.0 is matching to shear–wave speed of dirt 754, 377, 188, and 94samarium, severally.

These two mentioned parametric quantities, 0structure system [ 19 ] . Besides, with respect to nonlinear SSI incorporated in this parametric survey, the undermentioned non– dimensional parametric quantity is besides considered: img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/1571341.004.png"/ whereNitrogen,uouN, andSFdenote the dirt bearing capacity under strictly perpendicular inactive burden, the perpendicular applied burden, and factor of safety against perpendicular burden bearing of the foundation, severally.Degree fahrenheitis set equal to 1.2, 1.85, and 2.5 to stand for severely–loaded, instead heavily–loaded, and instead lightly–loaded foundations, severally [ 21 ] .

Peak value ofMRAiialong tallness of the construction is defined asPMRA. This index is compared in two alternate linear every bit good as nonlinear SSI status as introduced in Fig. 2. In 2nd instance, foundation upheaval and dirt output is permitted during dynamic time–history analyses. Comparison of the two SSI status reveals swaying isolation effects of foundation upheaval and dirt output on commanding accelerations transmitted to the superstructure when subjected to near–fault land dazes. To quantify the rocking isolations effects of nonlinear SSI on commanding familial accelerations, the undermentioned index is defined: img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/1571341.005.png"/ whereqacceldenotes maximal response acceleration ratio which is equal toPMRAat nonlinear SSI status,( NLSSI ) PMRA ( LSSI ) PMRAdivided by the same value at additive SSI status, . V. S HOCK RESPONSE SPECTRA ( SRS ) OF THE SOIL–STRUCTURE SYSTEMS Vibration transmissibility of the soil–structure systems is evaluated in this subdivision utilizing daze response spectrum. As illustrated in Figs. 3 and 4, the ordinate of each SRS curve represents theQratio as introduced in ( 6 ) . The abscissa T/Tof the SRS represents the ratio of the excitement pulsation continuanceaccelT to the natural periodThymineof the swaying isolation ( or natural period of swaying response of the foundation ) . Almost 16000 clip history analyses are performed in this survey. Consequently, the SRS braces with uninterrupted and dash lines in Figs. 3 and 4 represent mean and standard divergence ( s ) of the primary SRS curves ensemble, severally. The SRS braces are plotted with regard to different incident pulsation periods t to demo the consequence of daze strength. In Fig. 3 the consequence of dirt type on quiver transmissibility of the soil–structure systems is investigated through comparing SRSs for different values ofa, ( 3 ) . The consequences show that nonlinear SSI is likely to magnify the acceleration responses when subjected to long–period incident pulsations with0normalized period T/Ttranscending a threshold. It is shown that this threshold T/Tcorrelatives with dirt type. In more precise words, whenalessenings ( i.e. at more dense sites ) the threshold T/Tmoves to left as displayed in Fig. 3. For case, 0 the incident pulsation with normalized period greater than the threshold, T/T= 1.25, leads to response elaboration in a 10–story edifice located on really heavy site (a=0.25 ) . On the other manus, comparing single SRS curves on each graph of Fig. 3 reveals that increasing the land daze strength consequences in steeper inclines of SRSs. This fact shows that nonlinear SSI is more activated topic to incident pulsations with greater amplitudes. In Fig. 4 the consequence of incident pulsation type on quiver transmissibility of the soil–structure systems is examined through comparing SRSs of frontward directionality versus fling measure pulsations. The consequences show that long–period frontward directionality pulsations can ensue in important response elaboration, particularly when the pulse amplitude intensifies. In contrast, nonlinear SSI topic to short–period frontward directionality pulsations with high amplitudes can cut down the acceleration responses down to about 50 % for the 15–story edifice as presented in Fig. 4. In add-on, the two graphs of Fig. 4 depict that quiver transmissibility of nonlinear SSI is more period–dependent topic to send on directionality pulsations compared to fling measure land daze. VI. C ONCLUSION This paper concerns shock response analysis of the soil– construction systems induced by near–fault pulsations. To this terminal, quiver transmissibility of the soil–structure systems is evaluated utilizing daze response spectra. An in–depth parametric survey including about 16000 clip history analyses are performed. Medium–to–high rise edifices with different aspect ratios every bit good as foundations with different safety factors located on different dirt types are studied. Two types of near–fault land dazes, i.e. forward directionality and fling measure pulsations, with different pulsation periods every bit good as pulse amplitudes are selected as input excitement. Linear versus nonlinear SSI status are considered. Maximal response acceleration ratioQ is selected as quiver transmissibility index in additive compared to nonlinear SSI status. The consequences show that nonlinear SSI is likely to magnify the acceleration responses when subjected to long–period incident pulsations with normalized period T/Ttranscending a threshold. This threshold T/Tcorrelatives with dirt type, so that increasing shear–wave speed of the implicit in dirt, the threshold T/T lessenings. On the other manus, addition in land daze strength consequences in steeper inclines of SRSs, i.e. greater period dependence. Furthermore, comparing SRSs of frontward directionality versus fling measure pulsations reveals that long–period frontward directionality pulsations can ensue in important response elaboration, particularly when the pulse amplitude intensifies. In contrast, short–period frontward directionality pulsations with high amplitudes are significantly isolated. In add-on, quiver transmissibility of nonlinear SSI is more period–dependent topic to send on directionality pulsations compared to fling measure land daze. Mentions Piersol, A. G. , and Paez, T.

Henry David Thoreau was a rebel. Walden can be see Essay Example For Students

Henry David Thoreau was a rebel. Walden can be see Essay n as an account of hisrebellion. By the 1840s, life had changed throughout New England, even in theheart of Americas rebellion, Concord, Massachusetts. Thoreau wrote that I havetraveled a good deal in Concord (Krutch 108). He knew what he saw there, andwhat he saw, he began to despise. The mass of men lead lives of quietdesperation (111). In 1775, ordinary men had dared to take up arms of rebellionand strike a blow for independence and freedom (Bowes 123-124). Yet, in thespace of few decades, the combined forces of materialism and technology hadsubdued the children and grandchildren of these freedom fighters and reducedthem to slave-drivers of themselves (Krutch 110). Henry rebelled anddeliberately sought a new life in which he could be free and independent. Hedecided to leave Concord and seek answers to the mysteries of life in the solitudeof the woods and the beauty of the pond. On July 4, 1845, the anniversary of theproclamation of the United States independence, Thoreau went to W alden pond toproclaim his own independence (Literary 397). If the people of Concord had beenswept up by the speed of technology and the lure of money and property, Henrywould separate himself from these attractive deceptions and seek out the reality ofnatures truths, and not, when I came to die, discover that I had not lived. I didnot wish to live what was not life, living is so dear, nor did I wish to practiceresignation, unless it was quite necessary (Krutch 172). The quality of life throughout America was rapidly changing when Henrycast his critical eye on Concord. Where others saw progress and prosperity, hesaw wastefulness and poverty. We live meanly, like ants (173). The transcendentalists were deeply concerned about the quality of lifein America. A great tide of material prosperity, checked onlytemporarily by the crises of 1837 and 1839 and the ensuing Sweeney 2depression, had overtaken the country. Everything was expanding byleaps and bounds. Virgin territories were being opened to settlementfrom Illinois to Oregon. Turnpikes, canals, steamboats, railroads wererushed into being. The fur trade, overseas commerce, whaling, thecotton culture of the South, the factories of the North were bringingwealth to a happy nation. It was an era of good feeling, a time whenthe common man seemed to be getting his share of creature comforts. Yet sensitive observers feared that all was not well. It appeared notlikely that care for mans intellectual and s piritual nature might besubmerged into the rush for easy riches. What would be the profit inall this material advance if it were not matched by an equal progress inhumanity? So the transcendentalists pondered (Damrush et al. 6-7). Thoreaus response was to awaken from the deadly sleep brought on by thehum of the machine and the pillow of the dollar bills. Our life is frittered away by detail. An honest man has hardly need tocount more than his ten fingers, or in extreme cases he may add his tentoes, and lump the rest. Simplicity, simplicity, simplicity! I say, letyour affairs be as two or three, and not a hundred or a thousand; insteadof a million count half a dozen, and keep your accounts on your thumbnail. In the midst of this chopping sea of civilized life, such are theclouds and storms and quicksands and thousand-and-one items to beallowed for, that a man has to live, if he would not founder and go to thebottom and make his port at all, by dead reckoning, and he must be agreat calculator indeed who succeeds. Simplify, simplify. Instead ofthree meals a day, if it be necessary eat but one; instead of a hundreddishes, five; and reduce other things in proportion. (Krutch 173) Thoreau believed life to be too complicated and such things as internalimprovements to be nothing but furniture cluttering up a room. Americans werebeing confuse d and believed the illusions of luxuries of life to be beneficiary totheir happiness, but the people of New England could not tell what an illusionlooked like. They hadnt the time to notice nature or to distinguish illusions from Sweeney 3the real thing (173). Unlike Thoreau, New Englanders lacked a passion forobservation (Literary 394) for focusing in on nature. Life in New England movedtoo fast to notice

Speech Perception

WQuestion: Write a report on Speech Perception. Answer: Introduction Speech perception is the phenomenon through which the sounds of different languages are heard, understood, as well as, interpreted. Speech perception is very important and vital to understand the language that is used in our daily lives. When some individual speaks, there is fluctuation in the air pressure and the waves strike the individuals ears and in some aspect, the person is capable of turning these sound waves to the meaningful consideration of what the other person who is the speaker is saying about. Hence, the speech perception is the most important aspect that is used for the human communication. The core concept regarding the speech perception is used to explain the various mechanisms that are involved in the perception of the words correctly in spite of the inconsistent information that is provided by the various speech signals (Tvora-Vieira, Marino, Acharya, Rajan, 2015). The concept can be understood clearly by the fact that the human is able to perceive around fifty p honemes in one second in the language he/she is fluent, which indicates that the speech can be perceived with the marked rapidity. On the other hand, in case the person is not fluent in any kind of language (for instance, foreign language), the individual is capable of perceiving around two third of the single phonemic per second. However, there are various other factors affecting speech perception like frequency selectivity, loudness perception, intensity resolution, temporal resolution, temporal integration, pitch perception and frequency discrimination, binaural hearing, dead regions, as well as, aging. In this essay, we are going to discuss various factors that can affect the speech perception in noise for the person who are suffering from moderate to severe degree of post-lingual cochlear hearing loss (Pisoni, 2000). Speech perception in noise The developmental characteristics of the capability to understand the speech in the background noise can be attributed to the broad range of stimuli. There are various factors that can indicate the difficulties experienced by the individuals when listening and understanding the speech in the presence of noise in the background. Cognitive factors, involving attention, memory, as well as, fatigue can also affect the perception of the speech during difficult listening backgrounds such as in noise (van de Vijver, 2009). However, hearing loss is also one of the factors that contribute to the difficulty in perceiving sound in the noise, thus affecting the sound perception by the individual. Hearing loss is very common, and when it is severe, it can seriously affect and compromise the ability of an individual to understand the speech, the perception, and hence, the communication. Profound hearing loss can impact the spoken languages acquisition, as well as, its development, compromise the a ttainment of the education, and can affect the perception of the speech in the difficult listening backgrounds like in noise (Kitterick Lucas, 2016). Hearing loss is the unilateral or bilateral impairment of the hearing capacity. The post-lingual hearing loss is the hearing impairment that has developed or manifested after the speech has been developed in the individual, i.e., usually after the age of six years of age. Understanding the speech needs both the anatomical, as well as, functional integrity of central, as well as, the peripheral auditory system. Moreover, it also requires the acoustically appropriate context regarding the communication. However, noise may decrease the individuals probability of acoustic information that is available, and moreover, the noise is the parameter that is present in almost most of the communication situations. Noise impacts the understanding of the speech and hence, the speech perception in every person. This issue related to the speech perception in noise is compounded in the individuals with moderate to the minor hearing loss where speech, as well as, noise used to compete with each other a t the same time. Thus, affecting the perception of the speech in an individual (Bishop, Littman, Balko, Watson, Backous, 2003). There are various factors that can influence the sound perception in the post-lingual cochlear hearing impaired individual, which are going to be discussed further. Frequency selectivity: It is the ability by which the individual is capable of separating or resolving the multiple spectral peaks of the different sounds in the complex sound system. Frequency selectivity is directly associated with the bandwidth, as well as, the tuning of the auditory filters. There is a lot of variation observed in the frequency selectivity of individuals having the same thresholds of the pure tone. Hence, the ability of the ear to separate or resolve the sound components having different frequencies is the most important part of the speech perception, as well as, hearing in general. However, in the individuals having moderate to severe post-lingual hearing loss, the frequency resolving ability of the ear is compromised, hence, making them difficult to identify, as well as, impairing their ability to interpret and understand the speech. Therefore, the background noise is capable of worsening their ability to perceive the sound appropriately as the ear is less able to resolve or separate the different masking noise attributed to the noise environment from the target speech (Most Adi-Bensaid, 2001). Loudness Perception: Hearing loss is the decrease in the perception of the loudness or can be associated with the decreased speech intelligibility or can result in both the parameters. The quantitative unit used to measure loudness is known as decibel. The normal threshold of hearing is from 0 to 10 decibels. However, hearing loss can impact the sound perception ( i.e., partial or full loss of the pure tone) or can impact the understanding of the speech, also known as, the discrimination loss. The summation of the loudness is diminished in the post-lingual cochlear hearing loss individual. The post-lingual cochlear hearing impairment reduces the loudness, as well as, distorts the quality of sound. Hence, the environmental noise will interfere more in these cases as compared to the normal hearing individual with speech perception (Loebach, Pisoni, Svirsky, 2009). Intensity resolution: It is the ability of the individual to detect the various changes in the intensity of different sounds or to compare the differences in the intensity of the different or separate sounds. In post-lingual cochlear hearing loss individuals, the intensity resolution capability is decreased as compared to the normal hearing individuals. Hence, when noise is present in the background, the speech perception will be difficult in the cochlear hearing loss individuals due to decreased intensity resolution and discrimination of sounds of different intensities and frequencies (Kilman, Zekveld, Hallgren, Ronnberg, 2015). Temporal Resolution: Temporal resolution is the precision of the measurement of the ability of sound perception with respect to time. It is the ability of the individual to detect various changes or gaps in the different signals across time, as well as, across and within the different channel cues. The temporal resolution is measured with the help of three parameters that are gap detection task, the rate of recovery of the forward masking, and the TMTF. It has been observed that the individuals having post-lingual cochlear hearing loss have decreased performance the gap detection when noise is present, indicating more difficulty in following the temporal structures related to the sounds. Thus, having more difficulty in speech perception in noise. Moreover, the poor TMTF results into the poor perception of the speech in post-lingual cochlear hearing loss individuals (Jin Nelson, 2006). Temporal integration: It is the fundamental process, which the brain carries out for constructing coherent percepts from the serial of different sensory events. Deficits occurring in the temporal processing may impact the ability of the individual to understand the speech, more prominently in the noisy surroundings. The improvement in the various auditory thresholds by increasing the duration of signals is less in the individuals suffering from cochlear hearing loss in comparison to those with normal-hearing. Thus, the capability of the ones auditory system to integrate the required acoustic energy in sounds with noisy environment tends to appear reduced when there is presence of the hearing loss, hence decreasing the sound perception of those individuals in the noisy environment (Heming Brown, 2005). Pitch perception and frequency discrimination: Pitch is the qualitative dimension of the process of hearing that varies mainly as the function of frequency, or in other terms, it can be said that pitch can be defined as the perceptual correlate of the frequency. While, the frequency discrimination can be defined as the ability of the individual to reliably understand or perceive that the two sounds that differs only their frequency are different. However, in individual having cochlear hearing loss, the ability to discriminate between the frequency is reduced. Hence, separation of noise from speech is extremely difficult in the individuals having post-lingual hearing loss due to the various errors in the analysis of the pitch perception and frequency discrimination, which prevents accurate selection and hence, the speech perception from the noisy environment (Oxenham, 2008). Binaural hearing: It refers to the ability of the individual to integrate the information received by the brain from the two ears. Moreover, binaural hearing helps the ability of an individual to listen in the complex and noisy auditory environments, as well as, to localize the different sources of the sound. The advantage of the binaural hearing that occurs because of the spatial separation of speech, as well as, noise sources (for e.g speech occurring in the front while noise in the back) is reduced in the post-lingual cochlear hearing loss. Hence, the individuals with hearing imipairment have poor speech perception as compared to the individuals with normal hearing, as noise occurring on the contralateral side of the individual will be attenuated in the normal individual in comparison to the speech that is occurring on the ipsilateral side of the individual, and thus improving the speech perception (Moore, 2003). Dead regions: Hearing impairment or hearing loss is mostly associated with the damage or destruction of the hair cells present in the cochlea. However, in some cases, there may occur complete loss of inner hair cells function over the specific region of the cochlea, which is known as the dead region. Hence, due to the presence of the dead regions in the individuals having post-lingual cochlear hearing loss, there can occur off-frequency listening in the noisy environment, which means that the different frequency components can be perceived by the surrounding places. Hence, this frequency-place, as well as, temporal-place mismatch results in the decreased speech perception in the noisy environment (Jepsen Dau, 2011). Aging: Aging is found to be exacerbating factor in speech perception by the individuals having post-lingual cochlear hearing loss in the noisy environment. There is reduced recognition of the speech in the noisy environment by the individuals with hearing impairment, which is increased with the increasing age and hence causing reduction in the processing time, as well as, reduction of the necessary acoustic information present in the signal. With increase in age, there is poorer performance by the individual in detection of the modulation in the background noise, as well as, there is poor frequency selectivity, which is already experienced by the individuals with hearing impairment. Hence, aging increases the chances of reduction of speech perception by the individuals having post-lingual cochlear hearing loss (Innes-Brown Marozeau, 2015). Conclusion People having sensorineural hearing impairment have more difficulty in understanding and interpreting the speech, especially in the presence of background sounds. It has been observed that the speech perception by the individuals having hearing impairment is affected to the large extent by the presence of the noise in the environment as compared to the speech perception by the individuals having normal hearing ability (Tsuruoka, Masuda, Usui, Hattori, Takeuchi, 2009). The reduction in the individuals ability to resolve or separate the components of different frequencies of the complex sounds is found to be one of the major factor attributing to the difficulty of speech perception in those individuals. However, other factors like reduced ability of the individual to process the different temporal structure of the different sounds also plays the important role in the speech perception. The cochlea is the important and dynamic system, which operates on the various auditory signals in t he nonlinear, as well as, the time-varying manner. Hence, the temporal envelope, which codes the significant information from the speech, gets distorted when there is any kind of impairment in the auditory system, hence causing the distorted speech perception by the individual (Barac-Cikoja, 2004).
