The Adventures Of Huckleberry Finn, By Samuel Clemens, Also Known As M

The Adventures of Huckleberry Finn, by Samuel Clemens, also known as Mark Twain, is probably one of the greatest works of American literature ever written. Ernest Hemingway even said in his book The Green Hills of Africa, "All modern American literature comes from one book by Mark Twain called Huckleberry Finn" (Zwick). However, since Twain published Huck Finn 112 years ago, it has been the subject of much criticism, mostly all unfair. The Concord, Ma, banned the Adventures of Huckleberry Finn. Public Library immediately after its publication in 1885. They said the book was "rough, course, and inelegant...The whole book suited more to the slums than to intelligent respectable people" (as quoted in Clemens 285). Since the original banning of Huck Finn, it has been challenged and banned many times all over the country. Much question has been brought against Huck Finn as to its appropriateness for the reading public, and some of it rightfully so. Huck is not as strong in his morals as our parents and educators would probably like him to be. He is involved in several acts of theft. For example, shortly after the beginning of his journey along the river, he would go ashore and he "lifted a chicken that warn't roosting comfortable..." (Clemens 56). Huck smokes and cuts school. (Clemens 9 and 18) He engages in lying, when he impersonates a girl to visit St. Petersburg and when he tells the bounty hunters that Jim is white and implies that he has smallpox (Clemens 51 and 75). He lies many other times throughout the novel; Huck is a bad example to children who may read this book. Huck's plan to escape from Pap's cabin in the woods, which involves smearing pig's blood all over the cabin and making it seem like a murder had occurred, is an easy scheme for any smart youth to scare his parents with (Clemens 3 1). In October of 1997, a ninth grader in Hollister, California "borrowed" money from his parents and used it to fly to Hawaii. His mother believed that the boy got the idea from his hero, Tom Sawyer (Zwick). Critics claim that the book is full of ideas that cause impressionable children to do things like that (Ockerbloom). Opponents still have more negative arguments about the content of the book. Leslie Fielder, a literary scholar, believes that Huck and Jim engage in some type of homosexual relationship on the raft (Fielder as quoted in Clemens 416). The fact that Huck and Jim seldom wore any clothes on the raft only further substantiates this idea. Additionally, Twain intended Huck Finn to be a humorous novel. However, most of the humor, especially towards the end of the book in the Wilks brothers con, is in poor taste and "inelegant" Boston Transcript. Twain's poking fun at the Hare-lip, and the "long legged under taker" episode were not looked favorably upon at time of publica tion, but are not as much criticized now (Clemens 139 and 144). Today, the main objection to The Adventures of Huckleberry Finn is the fact that the book contains the word "nigger" more than two hundred times throughout the novel. As recently as last February, the Pennsylvania branch of the NAACP led a charge against Huck Finn to have it removed from required and optional school reading lists. But, when considering the issues involved, one must keep in mind that this book was written in a different time from that which we live in today. There was no such thing as politically correct. The word "nigger" was a word used commonly and unabashedly back then. So, how can we hold a book written over a hundred years ago to the literary standards of today? Huck Finn is not a racist book, in spite of Huck's initial racist standpoint. Through the course of the novel, Huck gains increasingly more respect for Jim, but still shows some racist attitudes occasionally. After the disagreement with Jim over the biblical story of "ole' King Sollermum", Huck remarks that "you can't learn a nigger to argue," thus implying Jim's stupidity (Clemens 65 and 66). Throughout the book, Huck plays tricks on Jim, which are also meant to make Jim feel stupid. Towards

IP Networking - Lab Report Example Company X headquarters has a total of four directorates and 400 employees. The department includes the executive leadership, research and development, human resources, and sales. Region 1 has customer service and accounting department, Region 2 has marketing and advertising department, while region 3 has inventory, manufacturing, and engineering departments. To accommodate the network growth the company will have to use the VLSM (Variable Length Subnet Mask) which was previously ignored by a consultant. This is after the company realized that all the network addresses are statically generated. This led to a high administration overhead when the networks and locations are added to the network. The company therefore has opted to come up with a standard IP addressing table for the WAN links and their locations. It has also decided to sample the configuration of Cisco for each and every location. Additionally, it will deny the users in Region 2 from accessing the offices of region 3 seri al interface.

Macro economics Essay Example | Topics and Well Written Essays - 1750 words

Macro economics - Essay Example Such announcement made by British Prime Minister gave rise to multiple speculations regarding the probable effect of such referendum on UK and the world economy. As no member nation has exited the union prior to this declaration of referendum, the degree of speculation has become more prominent. Recently, Mr. Cameron has downplayed the possibility of an early referendum on the ground that they will need more time to present better negotiations in terms of acquiring more freedom in trade relationships and other regulations. Accordingly, he announced that it will take at least till end of 2017 to draw a conclusion on EU and UK relationship. However, significant arguments have already been originated in support or against of such referendum (â€Å"Viewpoints: How experts see UK role in EU†). The paper will explore all such pros and cons of UK leaving European Union as identified by economists and politicians. UK holds a significant part in influencing regulations and policy formulations of European Union. However, recent measures taken by UK gave rise to the question whether the country should remain a part of EU or not. In the next segment, the arguments in favor of UK to remain as a part of EU will be analyzed. It has been observed for a long time that many European countries such as Switzerland and Norway are operating successfully in the global market without participating in EU. Both of the countries operate as single markets and do not follow any regulations or legislations incorporated by European Union in their national activities through agriculture, service sectors, home affairs etc. The countries are liable to take their own decisions regarding international trade and are not restricted by imposition of regulations by any third party. UK, in order to enjoy such freedom in enhancing their trade relations with all the emerging and economically advanced countries in the world, must come out from EU (â€Å"House of Commons†). Such

Follow the instruction and do the questions Essay

Follow the instruction and do the questions - Essay Example In his narrative or pamphlet, Common Sense; he talked about the distinction between the origins of society and origins of government. Paine drew the attention of people towards general facts and common senses by telling them that a society is formed because of their wants. He hoped that people understand that they are all dependent on each other for the satisfaction of their wants, as no person alone is sufficient. There is a chain as one depends on another and that another on some other and so on. They don’t need government for their safety but people themselves can do it. All they need is common consent and clear conscience as, they as a society are independent on each other and these needs never cease to exist. This belief on our own selves and on each other is weak, and that is the reason that people are still under the slavery of government who regulates their lives, rather than them taking charge of their own. 2) In Mark Twain’s â€Å"?1,000,000 Bank Note,† Henry Adams agrees to assist Lloyd Hastings in his investment venture in London. Henry tells Lloyd he does not want to buy mines; instead he wants to â€Å"keep my capital moving, in a commercial center like London† (76). Of course, having no assets, Henry cannot afford any investments. Yet what does it mean in Twain’s short story to keep one’s capital flowing? In fact, Henry amply succeeds in moving his capital, much to Lloyd’s and others’ benefit. How does the story conceive â€Å"capital†? The story â€Å"$1,000,000 Bank Note† by Mark Twain conceives money or capital as the most powerful object which can derive everyone and everything with its power. It can rotate the world on its axis. Henry Adams was a poor, lonely person who didn’t even have enough means to make his ends meet, but this 1000,000 note changes his life from a nobody to a socially high-class man. Even though he could not use or cash this note, just the word about him having such wealth made him an upper class and wealthy person. The story defines capital as a controlling force which gives a fame and era of authority to Henry just with the illusion of him being a wealthy person. Such was the supremacy of money that even others like Lloyd could benefit from this illusion created. The plot of the story is basically teaching the lesson that money is everything for the capitalist world and just the assumption of having wealth is enough for anyone to achieve success, fame, acceptance and love in this society. 3) Explain what Thorstein Veblen means by the term â€Å"pecuniary emulation.† Why does the emulative â€Å"habit of thought† engender â€Å"chronic satisfaction†? Pecuniary means anything related to wealth, and emulation means to make an effort or to have an ability to surpass others. Together the term â€Å"Pecuniary emulation† according to Veblen means to make an effort to surpass others in status as measu red by wealth. Veblen’s theory of the leisure class focused on the distinction of society between two classes, one who exploits and does not work and are called the leisure class, and other, a class of people who works in industry and produces goods. The thirst for wealth is never satisfied and gets only multiplied because of the power of wealth as a status symbol. Wealth brings a sense of accumulation, reputation and honor, which makes it impossible that the desire for wealth or

Isolation of β-Amyrin from Plant Parts of M. barteri

Isolation of ÃŽ ²-Amyrin from Plant Parts of M. barteri ISOLATION AND BIOLOGICAL ACTIVITY OF THE TRITERPENE Î’-AMYRIN FROM THE AERIAL PLANT PARTS OF MAESOBOTRYABARTERI(BAILL). Abstract Maesobotrya  barteri(Baill), belonging to the family EUPHORBIACEAE, is a medicinal plant growing widely in tropical Africa. The Aerial plant parts of Maesobotrya barteri (Bail) were collected fresh from Orokam, Ogbadibo local Government of Benue State, Nigeria in July, 2013. Taxonomical identification was done by Mallam Musa Abdullahi at the Herbarium unit of Biological sciences Department, ABU, Zaria, Nigeria. Pulverized aerial parts of Maesobotrya  barteri (960g) was exhaustively extracted successively using petroleum ether, chloroform, ethylacetate and methanol and concentrated in the rotary evaporator at 40oC. The ethylacetate fraction having the highest activity against test microbes from preliminary crude microbial screenings was subjected to phytochemical studies, antimicrobial analysis and column chromatography (CC). The column chromatography yielded fraction EN, which was further purified using preparative thin layer chromatography to give EN1. The structure of the isola ted compound was established using 1-D NMR and 2-D NMR spectroscopic analysis and by direct comparism with data reported in literature was confirmed to be ÃŽ ²-amyrin. The bioactivity of this compound was carried out using some clinical pathogens and the activity compared with standard drugs and this was found to be comparable with the standard drug. Keywords: Maesobotrya  barteri; Medicinal plant; bioactivity; Ethylacetate extract; ÃŽ ²-amyrin Introduction Maesobotrya sp is a variety of flowering plant belonging to the family Phyllanthaceae, or by some authors classified in Euphorbiaceae. The Euphorbiaceae plants are shrubs, trees, herbs or rarely lianas [1]. Plants of the Euphorbiaceae are known to be rich in terpenoids (69.5%) [2]. In Nigeria, the species M.barteri is under-exploited although the tree is of both medicinal and nutritional importance [3]. Maesobotrya species are used medicinally in different regions in Africa [4]. It bears succulent black-purple fruits that are edible and stain the tongue. The nutritive values of the fruits and seeds have been studied in Southern Nigeria [5]. Thus, this study aims at validating the antimicrobial effects of the aerial plant parts of Maesobotrya barteri used in traditional medicine in Orokam town of Benue State,Nigeria, as well as potent compounds that can be used as precursors for synthetic drugs. The presence of secondary metabolites in plants generally has been confirmed by [6], [7] and [8] through useful procedures and suggestions to get to targeted precursors which are of useful aids in the formulation of modern drugs. Plant Material The aerial parts of Maesobotrya barteri were collected from Orokam in Ogbadibo local government area of Benue State in the month of July, 2013. They were properly identified at the herbarium, Department of Biological Sciences, Ahmadu Bello University, Zaria. The whole plant was sorted, air dried under shade, segregated and pulverized by mechanically pounding them using wooden mortar and pestle. The pulverized plant material was stored away from moisture. Extraction 980.54g of the pulverized plant materials were carefully weighed and loaded into a Soxhlet extractor. It was extracted successively with Petroleum ether (60-80oC), Chloroform, Ethyl acetate (76-78oC) and Methanol by hot continuous percolation method in the Soxhlet apparatus for 72 hours respectively. Solvents used were those of JHD and general purpose reagents The extracts were concentrated in vacuo at 40oC using rotary evaporator and subjected to air drying to give dried crude extracts. Isolation The ethyl acetate extract was the most sensitive extract from the antimicrobial screening and was subjected to column chromatography (CC) for fractionation. Solvents used to run the column chromatograghy were sealed and are products JHD with 98% purity. Fifteen grams (15g) of the extract was dissolved in ethyl acetate and preadsorbed on 10.0g silica gel (qualikens 60-120 mesh). The dried pre-adsorbed extract was transferred to a mortar and ground to give a fine powder and was added at the uniform layer on top of the column. The petroleum ether descended on a horizontal line indicating that the column was well packed. A total of 105 fractions (50mls) each were initially collected using gradient elution with a solvent combination of petroleum ether and ethyl acetate, starting with 100% petroleum ether with an increasing polarity of 1% ethyl acetate. Similar fractions were pulled together based on monitoring from TLC. Fractions F20-F25 were pulled together at the ration of 8:2 and where subjected to further purification using Preparative thin layer chromatography to obtain a solid white amorphous substance which after several trails using different solvent combinations showed a single spot which was visible under the UV lamp and after spraying the TLC plate with 10% H2SO4 and oven dried for 5minutes at 60oC. The solid white amorphous substance produced was insoluble in ethyl acetate or petroleum ether but soluble in chloroform. Results and Discussion From the preliminary antimicrobial screening of the crude aerial plant parts extracts of M. barteri, ethylacetate extract exhibited the highest activity against the test microbes used via their zones of inhibition. Therefore, an activity guided isolation was undertaken. Bioactivity of Compound EN1 Pure Isolate The antimicrobial activities of compound EN1 isolated from ethylacetate extract of the aerial plant parts of M. barteri was examined and agar disc diffusion method [13] was employed for the determination of the antimicrobial activities. The pure compound was determined using some pathogenic microbes; the microbes were obtained from the department of Medical Microbiology Ahmadu Bello University Teaching- Hospital, Zaria, Nigeria. The determination of minimum inhibitory concentration was carried out using the nutrient broth susceptibility assay prepared according to the manufacturer’s instructions, as recommended by NCCLS [14]. Minimum inhibition McFarland turbidity standard scale number 0.5 was prepared to give turbid solution. Normal saline was prepared and was dispensed into test tube and the test microorganism was then inoculated into the normal saline, incubation was at 37oC for 6hrs, dilution of the microorganism in the normal was performed until the turbidity marched that of the McFarland by visual comparison at this point the microorganism had a concentration of about 1.5à Ã‚ ¥108 cfu/ml. Minimum Bactericidal and fungicidal concentration of compound EN1 was carried out to check whether the test microbes were killed or only their growth was inhibited. Mueller Hunton agars were prepared according to the manufacturer’s instruction, as recommended by NCCLS [14]. They were boiled to dissolve and were sterilized at 121oC for 15 minutes, the media were cool to 45oC and the medium (20ml) was poured in to sterile Petri dishes, the plates were covered and allowed to cool and solidify. The contents of the MIC in the serial dilution was inoculated on to the media, the media were incubated at 37oC for 24hrs for the bacteria and at 30oC for 1-7 days for fungi, after which the plate were observed for colonies growth. The MBC/MFC was the plate with lowest concentrations of the extract without colony growth. Table 2 shows the Zones of inhibition (mm) of the pure the compound EN1 from the ethyl acetate fraction which showed remarkable activity against twelve of the sixteen organisms tested. Compound EN1 could not inhibit the growth of Corynebacterium ulcerans, Candida albicans, Candida tropicalis, Aspergillus fumigates, Aspergillus nigre. The various minimum inhibitory concentration (MIC) and minimum Bacteriocidal concentration and fungicidal concentration (MBC/MFC) for the different microbes are as shown in Tables and the bioactivity of the aerial plant parts of M. barteri is comparable to the drugs Ciprofloxacin, Fluconazole and Fulcin used as positive controls.

Antimicrobial screening reported from other natural products has also confirmed the microbial properties of ÃŽ ²-Amyrin. ÃŽ ²-Amyrin was isolated from Ardisia elliptica [9], a medicinal plant used for alleviating chest pain, fever, liver poisoning and parturition complications. It was found that ÃŽ ²-Amyrin was six times as active as aspirin in inhibiting platelets aggregation. ÃŽ ²-amyrin was isolated for the first time fromLaurencia microcladia, marine algaedistributed widely in Egypt found to have antibacterial activity against Staphylococcus aureus, Bacillus subtilis, Salmonella typhi, Escherichia coli, and Pseudomonas aeurginosa [10].

The chemical shift at ÃŽ ´137.962, 125.9002 which are C-12 and C-13 and the consistent flow of methyl groups from C-23 to C-30 were characteristic peaks for a ÃŽ ²- Amyrin type of skeleton [11] and [12]. 1HNMR, 13C NMR and DEPTH spectra of the proposed compound ÃŽ ²-amyrin Figure1: 1HNMR Figure 2 : 13C NMR Figure 3: DEPT Table 4: Comparison of 13C NMR spectrum data of ÃŽ ²-amyrin Obtained from the Aerial parts of M. barteri with literature Carbon Position ÃŽ ´13CNM ÃŽ ´ppm ÃŽ ²-amyrin, Experimental ÃŽ ´13CNMR ÃŽ ´ppm ÃŽ ²-amyrin, Literature [12] ÃŽ ´13CNMR ÃŽ ´ppm ÃŽ ²-amyrin, Literature [11] 1 38.8495 38.7 37.3 2 27.2530 27.2 28.28 3 79.0731 79.3 71.85 4 38.7715 38.5 37.30 5 55.2568 55.1 36.81 6 18.3150 18.6 21.12 7 38.6441 32.4 42.35 8 39.5194 39.8 45.90 9 47.9239 47.6 50.18 10 36.7105 36.9 36.55 11 23.5770 23.6 24.33 12 125.9002 121.7 121.70 13 137.9624 145.2 140.81 14 42.0388 41.7 44.36 15 29.3557 26.2 26.13 16 21.1608 26.1 23.11 17 29.6969 32.6 48.48 18 47.5759 47.2 45.89 19 39.0811 46.8 39.82 20 30.6267 31.0 36.49 21 33.0001 34.7 34.00 22 37.0200 37.1 31.71 23 28.0359 28.0 29.3 24 15.5986 15.4 19.84 25 15.4777 15.4 19.10 26 16.9846 16.8 18.90 27 24.2027 25. 9 18.30 28 17.0954 28.4 19.20 29 28.1492 33.8 36.18 30 23.3098 23.7 19.42 Proposed structure EN1-(C30H50O, 426.7 g/mol) Name: ÃŽ ²-Amyrin or ÃŽ ²-Amyrenol Conclusion The isolation of ÃŽ ²-Amyrin from the aerial plant parts of M. barteri, whose bioactivity was established from this work by its zone of inhibition, is comparable to the drugs of Ciprofloxacin, Fluconazole and Fulcin. This justifies why the plant really serves as a general purpose antibiotic in traditional medicine in our society. The preliminary phytochemical screening also shows that the ethylacetate extract contains other classes of compounds that can be further isolated and tested for microbial activities and this can lead to chains of discoveries as the quest of precursors for modern drugs are continually on course.

Computer Changes and their Impact on Management :: essays research papers

Computer Changes and their Impact on Management The world of computers is a field that is not only very young, but is also rapidly changing. In one lifetime, computers have evolved from a multimillion dollar unit that filled entire buildings, to a few hundred dollar personal computer that fits on a desktop with more power than its predecessor. How does this change in cost, size and power affect our management decisions? To look at these areas, it should be understood that each characteristic not only makes a significant impact for management, but is enhanced by the other two changes.   Ã‚  Ã‚  Ã‚  Ã‚  The reduction in computer costs over time has the obvious implications of reduced overhead costs for a company’s management and possibly a smaller budget requirement for the information technologies department. Closer inspection of the lower computer costs shows that the reduced overhead can have a number of implications dependant on management decisions. One decision would be to show an increased profit on the end product’s margins. This makes stockholders very happy. Management could also decide to provide more computer technology for the company without an increase in budget, or provide hardware with less compromise in functionality. The additional money could be used for additional specialty computer hardware that would not normally be purchased. A company would have to research whether the increase in computer technology would be able to provide the necessary competitive advantages or productivity increases. Management might also decide to take an exhaustive look at the entire company and its business process’ to determine if other areas might use the money for upgrades as well. These upgrades can be in the manufacturing process, research and development, sales, or in manufacturing to name a few. The reduction in cost also impacts the reduction in size of the computer hardware which has been getting smaller and smaller. As the prices of computers have gone down, the manufacturers have been able to reduce the size of the computers dramatically at the same time. Management originally provided a computer that was very large with terminals provided to the user as an interface. Today we have a personal computer on almost every desk top. These units require less space allowing management the freedom to determine whether they wish to put a unit on every desktop. With the smaller space requirements and the changes in the hardware itself, management also has less impact to their facility requirements.

Small Objects: a Literary Analysis of Lullabies for Little Criminals

Small Objects: A Literary Analysis of â€Å"Lullabies for Little Criminals† In â€Å"Lullabies for Little Criminals,† there are many small objects that are relevant to Baby’s life. Objects can have remarkably profound effects on a person’s life, whether they are of sentimental value or another form of personal meaning, they have an impact on us. An object can mean many things to different people. An abandoned doll in a trash bin could be seen as old and ugly to an average person, but to the person who originally owned the doll; it could have been particularly special.In the novel, Heather O’Neil illustrates the effects of such objects on Baby and their symbolic meaning. In â€Å"Lullabies for Little Criminals,† there are three objects that represent Baby’s growth and change throughout the novel: the ragdoll, the knee- high socks, and the toy mice. When introducing her new friend Lauren to her room, Baby reflects on her rag doll,  "It was a doll that my mother had bought for me when she was pregnant . . . The doll also made me feel sweet inside, too, because it made me feel that at some point, even before I existed, I had been loved† (O’Neill 97-98).This illustrates Baby’s longing for a loving mother figure, which is a reasonable expectation from a 12 year old girl. Loving care is a critical need of any child. Baby does not have that feeling of being loved; therefore, she finds comfort in the fact that she was once loved. The doll is also representative of her current state of mind. Such as her wishes to be normal: have normal friends, normal parents, normal family; a normal life. When Jules destroys Baby’s rag doll out of anger, it is symbolic of a lost childhood.Her last reminder of the love her mother had for her had been torn away. Baby says, â€Å"Now I was nothing, a real nobody (O’Neill 119). The destruction of her doll meant that her sense of belonging, that she was once part of a family, was now gone. She seems as if she is being pulled into adolescence without having any real sense of true childhood. When the character Alphonse begins to take an interest in Baby, his first attempt to make Baby take an interest in him is to give her a gift. The gift is a pair of dainty knee-high socks.Baby wants nice things, and these socks were, according to baby, â€Å"the first pretty things I’d ever owned† (O’Neill 155). This gift is exhilarating for her. It is an acknowledgment from someone who believed she was attractive, especially coming from Alphonse. According the others in the neighborhood, it was known that Alphonse only looked out for good looking women, so if he took notice of someone, it meant something (O’Neill 148). It is particularly clear to the reader that Alphonse likely has ulterior motives, but to baby Alphonse is simply someone who likes her.The socks remind Baby that she is pretty, and she is proud of the fa ct that an older man found her attractive. In turn, this causes baby to trust Alphonse and fall for his manipulation, leading towards what could be a life of prostitution. The socks are symbolic of Baby being forced into adulthood. Baby is still young and naive; she has no way of understanding what Alphonse is attempting to do. Therefore, the socks may also represent Baby’s vulnerability and lack of ability to judge character.At this point in the novel, Baby has not had a proper childhood or even learned any of what it means to be a teenage person, and now she is already being pushed into adulthood. After Alphonse dies in the hotel room, Baby does not know what to do. She is lost without an adult. She realizes, â€Å"Even though I was making all the money, it seemed that since he was the adult, he was the only one who could get us a place to stay and food to eat† (O’Neill 309). It is clear that Baby is still mentally and physically a child, but has taken on the role of an adult.Since there is no longer an adult in her life, she is immediately overwhelmed. She does not think seeing Jules is a good idea (O’Neill 311), however, for some reason she is compelled to go to the shelter in which he is residing in. It seems that Baby’s situation may be hopeless. Baby’s arrival to the Mission seems to be the crucial turning point in the novel. She is presented with a family of toy mice, which baby believes to be â€Å"by far, the best gift I’d ever gotten† (O’Neill 317). An innocent and beautiful gift, which is exactly what Baby needs, something she has not had in an exceptionally long time.The mice are given along with the knowledge that she will be living Jules’s cousin from now on. The mice represent the possibilities of positive change in Baby’s life. They are symbolic of hope; the possibility that she will find what she needs. In â€Å"Lullabies for Little Criminals,† the use of obje cts to create symbolic meaning is abundantly evident and illustrates the roles Baby assumes as the novel progresses. She does not experience growing up in the same way most children do. She seems to go from child, to adolescent teen, to adult, in approximately a year.The roles she assumes show her growth in a manner that is unnatural to the reader, and the use of symbolism to show how this process is forced onto her is profound. The symbolism of the toy mice representing change shows Baby’s final step towards becoming a â€Å"normal† person. The author’s use of this immediately after the seemingly darkest point in the novel serves to create an emotional uplift for the reader; ultimately allowing the reader to realize that the character is going to be alright. The narrator states, â€Å"Then Janine stepped over to me and squeezed me hard.I could feel my heart beating when she hugged me against her, but now it felt fine . . . Her big blue eyes looked just like Ju les’s, and I guess mine too. Her green winter jacket smelled like rain† (O’Neill 330). The final paragraph of the novel shows that Baby will likely get exactly what she wanted: Love, a caring person, family, belonging, and most importantly, the opportunity to find herself.

Free Essays on Realizing Blake’s Vision

Blake’s poems explore a world that he envisions as the â€Å"two contrary states of the human soul† (Norton 37). He uses two books of poems, the Songs of Experience and the Songs of Innocence, to represent his different points of view. In these books, Blake uses companion poems to mix related content and imagery to represent his viewpoints of innocence and experience. â€Å"The Ecchoing Green† and â€Å"London† are two particular poems from these books that can be considered companion poems. Clearly Blake’s double vision about the world is satisfied by these two poems. They are linked to each other by their content and imagery and the establishment of opposing tones and settings. â€Å"The Ecchoing Green† from Blake’s Songs of Innocence is the first from this set of companion poems. Blake’s innocence poems are typically of a livelier and happier tone. In the first stanza, happiness and innocence are established by the sun rising, the skies being happy, and the spring being welcomed by birds singing and by other pleasant sounds (1-8). Carefree-ness is portrayed particularly in the next stanza by Old John laughing amongst the old folk as they all reminisce and laugh at their youthful past (11-20). Blake’s setting in the green field also portrays a place of carefree fun, a place to play loud sports and is presented as a more casual type of atmosphere. (The lively ecchoing green field is comparable to a present day community recreational park.) The most important images in the poem however are the children and the sense of family in the final stanza. After the children have wearied and the day draws to a close, their mother s and their â€Å"many sisters and brothers† are all compared to â€Å"birds in their nest,† who â€Å"Are ready for rest† (27-28). This comparison represents a peaceful end of the day with the children safely returning home to their caring mothers and families. The imagery of nature in this poem gl...

Free Essays on Methodic Doubt

Methodic Doubt Rene Descartes purposely identifies his work as â€Å"a meditation† and presents his thoughts using the first person. He doubts everything that he has admitted to up until this point because he feels that the senses can be deceiving. The senses, according to Descartes, were bad indicators to what is real because one, there is the chance of error and two; the actual experience of dreaming is misleading. Descartes thought that by doubting everything and anything, he could erase all other knowledge and begin to build from the base up. This idea is like an architects’, being that they must have a solid foundation before they can proceed. His ideas were very systematic, similar to those used by scientists and rational simply because he did not want to just add to things done earlier by others. He began with the determination to doubt all and take nothing for granted. While doing so, he stumbled across one proposition that he could not doubt. And that was his own existence. He stated that after all, the simple act of doubting presupposed something, which was engaging in doubt. This famous proposition is known as â€Å"cogito, ergo sum†: I think, therefore I am. Descartes concluded from this that at least one existential truth existed that we can claim to know. This was, that we, as individual persons, exist as thinking beings. It is on this premise that he attempts to base anything else because he felt that any secure philosophy must have a strong and secure starting point. It is from this point that he attempts to prove the existence of god and other things, which he thinks he can deduce. Following Descartes’ doubts of the senses he begins to doubt mathematics. He states the â€Å"Evil Genius Hypothesis.† This bold new idea states that maybe god is evil and that there is a higher being who likes to deceive others. With that in mind he states that this deception implies two things. First it imp...

How Going Public For Facebook Has Affected The Company Research Paper

How Going Public For Facebook Has Affected The Company - Research Paper Example Since that time, it has seen its users numbers grow to over 900 million users who are active. Handset devices are the majorly used by the Facebook subscribers. As typically anticipated, changing a company’s status from a private to a public status happens to be a commemorative period for the commercial entity holder, as well as, the management. The IPO signifies a reward for periods of thriving practices of the Facebook Company and the affirmative reception by the consumers. Nevertheless, the taking of the Facebook Company happened to highlight the significant weaknesses perhaps as an entity that is not geared up to see through the extra burden of finances and consequently lack of control. This is brought about by the initiation into the market of the stock exchange. As is the norm when preparing a company for an IPO issuance, a company cannot put out the information regarding its finances with any prospective investors or present investors through the quiet period. Therefore, investing in the company comes out blindly, a case that could make the investors lose their finances on the takeover supposing the company is overvalued as is the Facebook Company. In the process of making acquisition briefly after the IPO, since the overvaluation result in the unreasonably investors being buoyant, there is bound to be an overpayment. The challenges the Facebook Company has undergone since transforming its status into being a public company have posed numerous challenges to its undertakings. These challenges have consequently had a bearing effect on the company. Introduction The process of acquiring a public status of a trading company dealing in the stock exchange market from a private entity is not a procedure to be assumed lightly. The procedure is rigorous and takes up a lot of the financial resources, the dedication of management and the company’s time. However, the result of transforming into a public entity is significant as it comes along with an inc rease in the finances together with an increase in the level of awareness by the public. In addition, there is also the increase in the requirements of the legal nature and the corporate responsibility. Facebook Company’s intention of having IPO was essentially become traded in the public domain and consequently become bigger. Therefore, the individuals who put up their finances in the company through purchasing of the shares of the company gain a part of ownership of the company for an opportunity to share in the advantages of the company’s upcoming profits. For the owner of the Facebook Company, part of control he encompasses for the company was given up relative to the percentage of the company put up on sale. On top of being answerable to its shareholders, the Facebook Company has been opened to scrutiny by the government and the public. Nonetheless, the anticipation is that the Facebook Company will be able to generate extra capital resources as its capability to do so have been considerably improved. The general net worth of the company which is necessitated by the selling of the company’s stock, results in the company attaining such capabilities. The thriving of the stock of the company as was expected prior to the IPO was that it would play a part in the decreasing of any ratio of the debt versus the income, consequently assisting in the enhancement of the company’s score on its credit. Therefore, supposing the Facebook Company after attaining the public trading company status had successful stock provision, lenders can subsequently is found easily. This is because of the enhanced rating of credit
