Case study - Essay Example and Hasan, H., n.d.) At the outset, the environment although polite and formal, breeds division between management and employees. This is shown by the set up of physical structures, by not inviting employees to participate in management’s plan, with a notion that there is nothing more to learn from them. Result of this environment showed that while it was a good design of operational efficiency and control, there was no flexibility that resulted in loss of motivation and trust that led to unsatisfied performance in the long run. Because there is no chance of communication, even the best intentions could be clouded with suspicions as in what happened to John who failed to see the good intention of training and further development. If the democratic leadership is adopted, as initiated by new manager, there is a fair chance that employees will be more motivated in the work performance, John will not quit as things are communicated well, and system will lead to a collegial system whose basis is teamwork.

Interestingly, it is related to career opportunities, work life policies and job characteristics as could be seen with the problem of Suzanne Chalmers. Money, benefits and stress on the job are out of the question since these are not the reasons for her resignation. But why would she quit, along with other IT professionals who quit to later joining start-up software firms that give lesser benefits?

Cybersecurity - Coursework Example The N-gram list of Caesar encryption of the document itself would be the most effective for a cryptanalyst to use to decipher a text encrypted with the Caesar cipher as it shows the frequency of each character used in the document. As E is the most commonly used letter of the alphabet, seeing that the highest frequency letter is H with 148 different instances of the letter would indicate that H is the substitute for the letter E. With this known, it can be seen that there is a shift of 3 present in this particular cipher. Once that has been determined, it would be a simple enough task to pair up all the other letters with their associated substitutions, and then translate the document back to its original text. Q2. What do you notice about the histogram results when text is encrypted with the Vigenere cipher in comparison to the results of the Caesar cipher? Why is this the case? The histogram results of the Vigenere cipher show an increase in the frequency of the letters that were u sed in the code word â€Å"applesauce† that encrypted the document. The Caesar cipher does not show this kind of across the board increase in particular letters due to the fact that it does not work off of an encryption key of this nature, but works instead off of an alphabet shift. Q3. There is an error in the following cipher text representation of this quote; what is it? What should the correct cipher text be? SDAHFOWGRABSSRERIVBYBSCIMQTFNIVETGHBSNQCNCSDTDHBSNQCD ECNICIFCTIC The error in the following cypher text occurs in the fourth to last letter of the text.

Q4. Of the three ciphers discussed (Caesar, Vigenere, Playfair), what are their relative degrees of secur ity and why? Of the three ciphers discussed, the Caesar is the easiest cipher to break. This particular cipher may be found and used by anyone of any age; I can remember using it back in elementary school in order to pass notes in class. The Vigenere cipher is a bit stronger, requiring a more complex method of analysis in order to determine the proper code needed in order to unlock the â€Å"secret message.† It is the Playfair cipher, however, which shows itself to be the most secure of the three ciphers, as it removes all spacing, or generates its own spacing after every second character, making it impossible to guess the word without the need to â€Å"crack the code† first.

The Effect of Television on the American Culture Essay Example for Free

The Effect of Television on the American Culture Essay The television has positioned various issues pertaining to the lives of the general public in a number of ways. Undoubtedly, views and opinions of the public may be easily controlled and influenced through content of various commodities of television. People opinions may perhaps form by their views on certain subjects. Starting slightly beyond infanthood, children learn to engage in, duplicate, and imitate the accessories and fashions from movies, sitcoms, commercials, and television. Additionally, apart from producing awareness for adults, television activates certain images of ideas and factors into the minds of children. For example, television stereotype groups, in which various movies and sitcoms display how model youths act in educational institutions and individuals with turbans and beards must be terrorists. Stereotypes embed in the minds of children, and they become persuaded to pursue them in real life. Furthermore, celebrities accepting characters with nudity and cussing, creating the opinion of children and adults that it is acceptable to compromise roles and broadcast Christ. The Bible says, â€Å"And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.† Television is significant to the media. Currently, television inundated a massive amount of communication that has an enormous effect in the lives of American culture. The American culture has a vast amount of information through television; it becomes very difficult to distinguish between right and wrong, or to decipher vital information from true and false. It is apparent that television has significant effect on young people, and these days practically all of them have access to television because of easy accessibility and it presents the highest degree of simulation. Visually being simulated inclines that television has an assorted kind of effect on attitudes and lives of people. It is debatable what people watch on television might shape their attitudes and behaviors that individuals holds in contradiction of or in favor of numerous issues. Such as, a television  show continuously showing youth wearing fashionable clothes with makeup, clearly, a youth that keep viewing the same ideas, views and images imposed on them by the associated media like internet and magazines, it is possible that they will begin to believe and accept similar ideas. Similarly, television may work in creating a variation of stereotypes, for instance, in high school, popular girls that are fashionable and rich, these girls become embedded in the minds of youn g girls as they are viewing television and its’ likeness. As a result, such images cause young individuals to shape certain stereotypes, attitudes, notions and ideas towards events and people surrounding them through showing what the intellect desires them to view, in which, unsurprisingly reality does not exist. We are to, â€Å"Therefore be imitators of God as dear children.† Still, television has created stereotypes from diverse cultural and social backgrounds. Such programs produces a sense of how an individual represent themselves, how an individuals’ impression in relation to ethnicity, gender and nationality they belong to or about their sexual orientation on themselves and others. Perhaps, the most significant misconception that a person may obtain from television is the description of other ethnicity or customs, which creates confusion and wrong assumptions in the mind of a child concerning people who belong to specified cultures. Studies have confirmed that television is a key influence on how to think, behave, feel, fear and believe of individuals from other ethnicities. For instance, most of action television programs present a female in distress and a male occurs to save her most times. This refers to a typical gender stereotyping, where the female portrayed as the weaker gender or sex always require rescue from a male for protection. Young people learn to respond to different ethnic groups from the knowledge attained via television programs. Such as, television programs on several occasions have depicted African Americans as generally proficient and skillful sport players. Whenever people view people playing sports, assumptions are that African American athletes are better performers than Caucasians. Above views does not assert that excellent quality cannot originate from television. A range of television programs disseminate and provide youth with massive meaningful information, for instance documentary films on National Geographic and Discovery channels pertaining to diverse events and issues in the lives of people. This positive side of television  shows, usage is a responsible, factual, and focused methodology. Society has the insight in evaluating the facts provided. These are popular television shows, which incorporate world stimulated views and opinions into the minds of people. Educational programs provide a unique amount of facts and information on diverse cultures across the world, and are beneficial in enhancing knowledge and eradicating the misconception about cultures and diverse people. In conclusion, television possibly has several significant effects on the lives of American people, for example the influence of attitude and belief of people, especially young people. Children watch television programs that could create a positive or negative impact on their minds concerning certain opinions and views. Worldwide, youth should be informed and aware of the different viewpoints that penetrate television programs, as well as implications on the different divides and cultures of society. It is apparent that television programs significantly influence the lives of people, especially children. Television programs may possibly shape opinions and views of youth in any direction, because children distinguish directly what is seen on television programs. Programs based on facts and reality may help young people comprehend society in a good manner that eventually directs them to progress. Horror television programs may have a negative influence on development of a child, which could result in long-term anxiety and fear. Altogether, these influences have a major impact on the learning and developments of children, the role of children are the future of all nations. The Bible says to, â€Å"Train up a child in the way he should go, [a]nd when he is old he will not depart from it.†

Preparation of Terbium Hydroxide Nanowires by Hydrothermal

Preparation of Terbium Hydroxide Nanowires by Hydrothermal The preparation of Terbium hydroxide nanowires  by hydrothermal method The single-crystalline Tb(OH)3 with various morphologies was successfully prepared from Tb2O3 powder by adjusting the concentration of acetic acid under hydrothermal condition. The influence of the concentration of acetic acid and reaction temperature on the crystalline phase and morphologies of Tb(OH)3 products was discussed. The concentration of acetic acid plays a key role in determining the products morphology. Eventually, the mechanism of acetic acid on morphology of products was deeply discussed. Keywords: Tb(OH)3, nanowires, spindle, rare earth, hydrothermal. Introduction Rare-earth elements are a group of 17 chemically similar metallic elements, including the 15 lanthanides, plus scandium and yttrium because of their similar chemical properties. The oxides of rare-earth elements have been extensive used in past decades because of their optic, electric, magnetic, and catalytic properties, which are caused by their unique electronic structures and numerous transition modes involving the 4f shells of their ions. These properties strongly depend on the composition, morphology and dimensionality of products, which are sensitive to the bonding states of rare earth ions. In recent years, many important materials have been prepared in the form of nanowires to generate some unexpected properties. Nanowires represent a class of quasi-one-dimensional materials, in which carrier motion is restricted in two directions so that they usually exhibit significant photochemical, physical, and electron-transport properties which differ from that of bulk or nanoparticle materials. Recently, three dimensional (3D) nanostructured architectures have been explored for a new generation of advanced devices such as supercapacitors, fuel cells, and sensors owing to some improved properties originating from their nanobuilding blocks and the manners in which they are organized. Up to now, a wide variety of inorganic materials, including metal,6a metal oxide,6b–d hydrate,6e borate,6f molybdate,6g,h and tungstate,6i have been successfully prepared with complex 3D hierarchical shapes by the solution-phase chemical method, due to its low cost and potential advantage for large-scale production. However, exploration of reasonable synthetic methods for controlled construction of complex 3D architectures of other inorganic functional materials via a chemical self-assembly route is still an intensive and hot research topic. In the controlled construction of self-assembly of 1D or 2D nanobuilding blocks into 3D novel nanoarchitectures, copolymers and surfactants always play important roles due to their directing functions during the aggregation process as well as their stabilizing effects in equilibrium systems. [Lu-1] For example, who and who reported the Who et al. have described systematically the †¦ However, there are only several report on the synthesis of Among the family of rare earth compounds, the terbium oxide is the important functional rare earth material. It had been used as a promising candidate for ceramic pigments, catalysts, promoters and stabilizers in combustion catalysts, oxygen-storage components, and materials with higher electrical conductivity. In addition, terbium hydroxides are of great importance because rare earth oxides can be straight formed through dehydration from hydroxides. To date, many terbium hydroxides particles have been synthesized via a hydrothermal route due to the advantages of high purity and good homogeneity, and the corresponding structured rare earth oxides were made by calcining the precursors. [Lu-1] In the present work, we exploited a one-step hydrothermal route to prepare nano-scale terbium hydroxide with various morphologies. In addition, the mechanism of acetic acid on morphology of products was deeply discussed. The reaction mechanism leading to the lutetium oxide precursor and the self-assembly process were discussed. A possible formation mechanism for the morphology evolution of these microstructures was suggested, which was not reported before. Experimental section: 2.1. Preparation of Tb(OH)3 precursors All chemicals with analytical grade were purchased from Wako Pure Chemical Industries, Ltd., Japan, and used without further purification. A detailed description of the preparation process is as follows: 15 mL of acetic acid solution with various concentrations (0.001~0.2M) and 0.45 g of Tb2O3were placed in a 25 mL Teflon-lined autoclave. The autoclave was sealed, heated in an electric oven to 200  °C at a heating rate of 5  °C/min, and maintained at 200  °C for 6 h with rotation for agitation. The autoclave was then cooled to room temperature via air quenching. The precipitate was collected using a centrifuge, washed with distilled water, and dried at room temperature. In order to investigate the mechanism, the reaction temperature and reaction time were appropriately changed. The pure water, sodium hydroxide and the other type of solutions were used as the solvent instead of acetic acid solution. 2.3. Characterization Powder X-ray diffractions (XRD) were performed using a Rigaku RTP-300RC diffractometer operating at 40 kV and 100 mA with Cu Kà ¯Ã‚ Ã‚ ¡ radiation (à ¯Ã‚ Ã‚ ¬) 1.54056 ÃŽ ¼m. The patterns were collected in the range of 10 ° to 70 ° with a 0.02 ° step and scanning speed of 4 °/min. The micrographs of field emission scanning electron microscopy (FE-SEM) were obtained using a JEOL JSM-6500F electron microscope operating at 15 kV. The samples were heated in air at a ramp rate of 10  ºC/min. Fourier transform infrared (FT-IR) spectra were obtained using a Shimadzu FTIR-8200PC spectrophotometer at room temperature. Result and discussion 3.1. Influence of acetic acid concentration on the phase and morphology of the obtained precursors The chemical composition and crystal structure of the samples were firstly determined by XRD measurements. Fig. 1 shows the XRD patterns of as-prepared samples in the various concentrations of acetic acid solution. It is easy found that when the concentration of HAc was lower than 0.15M (fig.1a~e), the XRD patterns can be indexed to be a pure hexagonal phase of Tb(OH)3, in agreement with the reported data (JCPDS 83-2038) with lattice constants a=6.3150 Ã… and c=3.6030Ã…. With the enhancement of concentration of HAc, the intensity of main diffraction peak (100) gradually reduced, meanwhile the full width at half maximum (FWHM) increased gradually. It means that the crystallinity of products and crystalline grain were gradually decreased. It is important to note that the relative intensity ratio of (110) and (101) peaks was changed with the increse of concentration of CH3COOH, suggesting that the preferential growth along c-axis occurs with the increse of concentration of CH3COOH . When the concentration was further increased to 0.2 M, an unknown phase was formed. The XRD patters showed the compound have the layered structure according to the d value. In order to determine the chemical composition of the unknown phase, the Infrared spectra was allowed to use. Fig.2 shows the FT-IR spectra for the as-prepared simples. The typical peaks of Tb(OH)3 products (fig2.a~e)were found at ca. 3610 and 670 cm-1. In accordance with the results in literature, these two bands can be associated with OH stretching and with Tb-OH bending modes in the hydroxide[à ¦-†¡Ãƒ §Ã…’ ®]. The FTIR spectra show that these products are free of organic byproducts. The IR spectra of the unknown phase (fig2.f) show additional adsorption bands at 3380, 2924 , 2853,1568, 1443 and 1011 cm-1. The occurrence of a broad 3390 cm-1 band is attributed to residual traces of water in the sample. The bands at 2924 and 2853 cm-1 correspond to –CH3 stretching and –CH3 against stretching vibration, respectively. These bands are located between 1568 and 1443 cm-1, which are typical for stretching vibrations of carboxylate groups Va(COO-) and Vs(COO-), resp ectively[à ¦-†¡Ãƒ §Ã…’ ®]. The band at 1011 cm-1 corresponds to Tb-OH bending vibration. On the basis of the IR spectraà ¯Ã‚ ¼Ã…’the precursor material is assumed to contain metal acetate hydrate and metallic hydrate (Tb(CH3COO)X(OH)Y†¢H2O). The SEM images of several typical samples with distinct morphologies are presented in Fig.3a-f. It is found that the concentration of acetic acid (HAc) plays a key role in determining the product morphology. Tb(OH)3 could be obtained at concentration between 0.001 to 0.15M. At low HAc concentration (fig.3a), the obtained product is composed of granular aggregates and it was difficult to distinguish each other. A slight increase in concentration to 0.01M (fig.3b), the morphology changed to microfibers of nanowires aggregated with diameter of 1.5 ÃŽ ¼m and length up to 5 ÃŽ ¼m. It is easy to find that these microfibers were composed of bundles of nanowires. The diameter of these nanowires ranges from 50 to 100 nanometers. As HAc concentration was further increased to 0.03M (fig.3c), the spindle-like structures ranging in diameter less than 2ÃŽ ¼m and length more than 10ÃŽ ¼m were obtained. When HAc concentration was added to 0.1 M (fig.3d), the length of the bundles of nanowires was fu rther increase to more than 12ÃŽ ¼m along with the decrease of the diameter. At the same time, the diameter of the nanowires also gradually reduced. To further increase the concentration of HAc to 0.15M (fig.3e), the bundles of nanowires began to varying degrees of separation, some single nanowires began to form. These nanostructures are found to be in a wide scale of size, ranging in diameter from less than 12ÃŽ ¼m to more than 2 ÃŽ ¼m. Finally, when the concentration was further increased to 0.2 M (fig.3f), the SEM photograph also showed that this compound consisted of plate-like crystals, which is in agreement with the XRD result. 3.2à ¯Ã‚ ¼Ã… ½Effect of temperature To determine the effect of temperature, the Tb2O3 with 15ml 0.067M CH3COOH solution were hydrothermally treated at 100, 160, 200, 220à ¢Ã¢â‚¬Å¾Ã†â€™ for 6h. According to the XRD patterns, the pure phase of Tb(OH)3 was only obtained at hydrothermal temperature above 160à ¢Ã¢â‚¬Å¾Ã†â€™, while only a small amount of Tb(OH)3 was formed at 100à ¢Ã¢â‚¬Å¾Ã†â€™, and most of products proved to be raw material Tb2O3. With the increase of reaction temperature to above 160à ¢Ã¢â‚¬Å¾Ã†â€™Ãƒ ¯Ã‚ ¼Ã…’the raw material Tb2O3 disappeared, and pure phase of Tb(OH)3 was obtained. When the temperature was increased to 220à ¢Ã¢â‚¬Å¾Ã†â€™Ãƒ ¯Ã‚ ¼Ã…’the crystallinity of Tb(OH)3 was significantly increased. The hydrothermal temperature has a great impact on the size of the terbium hydroxide precursors. Figure 5 shows typical SEM images of Tb(OH)3 in 0.067 mol/L HAc solution at various temperature. It can be seen that the a few microfiber-like structure of Tb(OH)3 was formed at low temperature of 100à ¢Ã¢â‚¬Å¾Ã†â€™(Fig.5a). When the temperature reached to 160à ¢Ã¢â‚¬Å¾Ã†â€™, the uniform microfibers of Tb(OH)3 nanowires with length of about 13 à ¯Ã‚ Ã‚ ­m were obtained(Fig.5b). With the enhancement of reaction temperature, the length of microfibers gradually increased, as well as the diameter of nanowires (inset in Fig.5b and Fig.5d). The more quantity of microfibers was formed at high reaction temperature than the low temperature. In addition these microfibers grew very slowly as the extension of reaction time at high temperature of 220à ¢Ã¢â‚¬Å¾Ã†â€™. Details of results are as shown in table1. That is because the reaction rate of the dissolving – recrystallization increases at high temperature, a large number of crystal nucleus has been quickly formed in the initial stage of reaction. In the case of no changing the total amount of raw materials, the smaller grain size has been formed under the condition of higher temperature. Meanwhile, the defect of products is less at high temperature than low temperature. Therefore the diameter of nanowires of microfibers at high temperature is bigger than at low temperature. 3.3. Effect of reaction In order to understand the reaction process, the reaction time was changed from 0 to 24h, while the CH3COOH concentration and reaction temperature were fixed to 0.067M and 200à ¢Ã¢â‚¬Å¾Ã†â€™, respectively, Figure 6 show the XRD results of samples received after 0 h (just when the oven reached 200 °C at a heating ramp of 5 °C /min), 0.5h, 2h, and 6h of hydrothermal reaction at 200  °C, respectively. According to the XRD patterns, when the oven reached 200  °C, the characteristic peaks of hexagonal Tb(OH)3 just began to appear in the XRD pattern, as shown in Figure 6a. Most of the characteristic peaks proved to be raw material Tb2O3. The pure phase Tb(OH)3 could be obtained after 30 min of hydrothermal reaction, and with the enhancement of reaction time, the intensity of main diffraction peak (100) gradually increased. It means that the crystallinity was gradually increased with the reaction time increased. Figure 7 shows SEM images of samples received after 0 h (just when the oven reached 200  °C at a heating ramp of 5  °C /min), 0.5 h, 2 h, 6 h, and 24 h of hydrothermal reaction at 200  °C, respectively. When the oven reached 200  °C, the product is composed of starfish-like microstructure (Figure 7a). With the increased of time to 0.5h(fig.7c), the morphology changed to microfibers of nanowires aggregated with diameter of 1.5 ÃŽ ¼m and length up to 5 ÃŽ ¼m. It is easy to find that these microfibers were composed of bundles of nanowires. As time was further increased to 6h (fig.7d), the spindle-like structures ranging in diameter less than 1.5ÃŽ ¼m and length more than 10ÃŽ ¼m were obtained. Finally, when time was increased to 24h (fig.7e), the nanowires of the spindle-like microfibers began to split. 3.4 the effect of CH3COOH on morphology According to the above phenomenon, CH3COOH plays a key role in determining the morphology of products. To determine the effect of CH3COOH on morphology, the pure water, sodium hydroxide, CH3COONa, HCl, oxalic acid and ascorbic acid (L-Ac) solution as the solvent instead of acetic acid. From XRD patterns we can see, no matter what kind of solution was used as a solvent, the pure phase Tb(OH)3 could be obtained. In 5M NaOH solution, the product was composed of nanorods aggregates. In pure water, nanoparticals and some mocrorods aggregates were obtained. (à ¦Ã‚ ¯Ã¢â‚¬ Ãƒ ¨Ã‚ ¾Ã†â€™Ãƒ §Ã‚ ¢Ã‚ ±,à ¦Ã‚ °Ã‚ ´,à §Ã¢â‚¬ ºÃ‚ Ãƒ ©Ã¢â‚¬ ¦Ã‚ ¸,à §Ã‚ ¡Ã‚ Ãƒ ©Ã¢â‚¬ ¦Ã‚ ¸,à ¨Ã‚ Ã¢â‚¬ °Ãƒ ©Ã¢â‚¬ ¦Ã‚ ¸,à §Ã‚ »Ã‚ ´Ãƒ ¤Ã‚ »-à ¥Ã¢â‚¬ËœÃ‚ ½c) Figure 9. SEM images of products synthesized from 0.45g of Tb2O3 in (a)10M NaOH solution and (b) pure water at 200 oC for 6h. Conclusion We have used terbium oxide and different concentrations of acetic acid to synthesize the single-crystalline Tb(OH)3 with various morphologies by a hydrothermal method. The concentration of acetic acid, reaction temperature, reaction time and types of solvents strongly affect the morphology and size of products. The morphology of the Tb(OH)3 products changed from granular aggregates, to microfibers of nanowires aggregated, spindle of nanowires, eventually into nanowires with increasing concentration. The crystallinity of the Tb(OH)3 products can be increased by enhanced the reaction temperature. The method utilized in this study to fabricate the terbium hydroxide with tunable morphologies is general and could be extended to synthesize the other rare earth hydroxides by simple adjusting the concentration of acetic acid.

Give Children the Vote? I Vote No Essay -- Essay Critique Children Vot

Give Children the Vote? â€Å"What I suggest is that children be allowed to grow into their own right to vote at whatever rate suits them individually,† argues Vita Wallace as her major claim in the essay â€Å"Give children the vote† (1998, p.147). This is a thoughtful argument by Wallace, but I disagree with it. In this essay, Wallace presents her opinion, but the major claim could also be presented as a fact, judgment, or policy (McFadden, 2003). Throughout the essay, I see the interesting approach Wallace takes to try convince the audience. In my opinion she is unsuccessful. Wallace’s major claim, giving children the vote, is a good one and something many kids cringe about these days. She presents this argument in defense of kids, including herself, which she feels are being discriminated against. Wallace was home schooled, so she believes children should not be punished for choosing not to attend school. She continues saying, â€Å"Learning about discriminatory laws preventing high school dropouts from getting their driver’s licenses†¦Ã¢â‚¬  (1998, p.145) made her think about the unfair treatment of kids. Realizing all the rights children miss out on, Wallace focuses on the right to vote. She was 16 when she wrote this essay and feels ready to vote. In fact she states, â€Å"I think I would not have voted until I was eight or nine, but perhaps if I had known I could vote I would have taken an interest sooner† (1998, p.147). The qualifiers also play a big role in â€Å"Give children the vote.† A qualifier is a word or two that modifies the claim (McFadden, 2003). Wallace does a good job with the qualifiers, and makes the claim stand out a little better. Wallace’s major claim, again, is children should have the right to vote. But ... ...-election depends on the well-being of the voters† (1998, p.146). Here, again, she uses a statement that has no evidence and more importantly, doesn’t even focus on the issue of kids voting. Wallace has worthwhile ideas, but I believe she needs to develop her research methods and legitimate arguments. Unfortunately, she uses her own examples, reasoning, and analysis to argue for the claim to allow kids to vote. Credible sources or harder evidence might be more useful in Wallace’s case.

Korea: MacArthurs war with Truman :: essays research papers

Korea: MacArthur’s war with Truman 1946-1952 The movie starts out with a pretty good background on the whole Korean War. It tells of how after WW II, Korea, at that time was ruled as a colony of Japan, was split along the 38th parallel. With the Russians controlling North Korea, and the U.S. backing South Korea. Both the U.S. and the U.S.S.R. chose leaders from the countries to be more of a governor than a president for the two nations. MacArthur, though in many ways was a failed general in that he lost many troops and strategic strong holds, was still a very popular â€Å"hero† from WW II. Although it depends on who you talk to. My great-grand father was U.S.S. Colorado and everyone in the Pacific during the was thought MacArthur was a horrible leader, and commander. MacArthur tended to make his own choices on U.S. foreign policy. MacArthur wanted to take troops all the way up to the Yule River on the border of Korea and China. Truman hated MacArthur for this, absolutely hated him. Truman felt that MacArthur’s daring had unduly escalated the war. China was now involved, and Truman feared Russia was to follow. Even though at that time Russia was considered a friend, Truman knew it was only one major conflict away from another world war. MacArthur wanted to bring in Chinese nationalist from Thailand into the war and attack Mainland China. MacArthur even went as far as to fly to Thailand and meet with na tionalist leaders to discuss doing so. MacArthur even suggested using up to 20 atomic bombs on strategic Chinese locations. He did not want his soldiers to die for a stalemate, he wanted total victory. Both Truman, and the U.S. Joint Chief’s of Staff (a collection of high ranking officers from all of the armed forces) disapproved of MacArthur’s actions, but were reluctant to do anything about it because of his tremendous popularity. In Tokyo, MacArthur met with diplomats from Spain and Portugal, and made it clear he wanted war with China. The diplomats related this to their home governments in telegrams that were intercepted by the NSA (National Security Agency). This was reported to Truman and he knew that MacArthur needed to be fired. The problem was that Truman could not report that the US had been listening in on other countries secret communications. So Truman was forced to wait until there was another reason to let MacArthur go, one that could be published and not embarrass the US.

Long Day’s Journey Into Night

In Eugene O’Neill’s play A Long Day’s Journey into Night, the main protagonist, Mary Tyrone, functions as an instrument of suffering of others. Her sons Jamie and Edmund both suffer internal tragedies that could easily be blamed on her. Like her sons, her husband Tyrone faces his own internal conflicts, some of which are because of Mary. Mary Tyrone is a â€Å"recovering† addict who has an extremely hard time admitting her problem and is sometimes in denial about her problem. Her denial is a huge factor in the suffering that her sons and husband have.Jamie, Mary’s eldest son, is an alcoholic that undermines his brother. In the earlier half of the play the reader learns from Tyrone that Jamie hates Edmund and is extremely jealous and angry towards him. This becomes evident later on the in the play when Jamie tells Edmund how he feels using terms such as â€Å"Mama’s baby and Papa’s pet†¦Ã¢â‚¬  (167), showing the reader his enviou s feelings. Jamie is jealous towards Edmund and resents the fact that he was ever born. Because all of Jamie’s jealousy is due to Edmund’s birth, the true blame and jealousy is toward Mary for giving birth to Edmund.Jamie knows, as well as Mary, knows that the reason for Edmund’s birth was due to the loss of her second son Eugene. After Eugene died Mary felt lost and empty and decided to give birth to a third child, Edmund, in hopes of helping her cope with the loss of her second son. Knowing this adds to Jamie’s jealousy towards Edmund and his bitterness towards his mother. Not only is Jamie angry at his mother for having Edmund, he is angry at her for being in denial of her problem.He knows that his mother is a morphine addict but cannot accept the fact that she won’t admit she is back into her habit. Her addiction causes his addiction. Jamie’s anger towards his mother’s obsession causes him to drink. The more Mary denies her action the more Jamie drinks. Although he is aware of her addiction, he tries cover for her by making up little excuses to her whereabouts and or her physical appearance. Edmund, like Jamie, is also aware of his mother’s morphine addiction but makes excuses of Mary’s actions and appearances to his brother and father.Both Edmund and Jamie hope that by covering for their addicted mother, they will be able to salvage what is left of their broken family. During the play Edmund learns that he has consumption or tuberculosis. This means that he will have to spend up to one year in a sanitarium. After it is learned that Edmund got consumption when he went to foreign lands earlier in life to escape the troubles of his family, it is easy to blame Mary Tyrone for his illness. There would have been no reason for Edmund to escape his family if his mother was not addicted to morphine.If Mary wasn’t an addict than it is highly probable that Tyrone and Jamie would not be alcoholics and Edmund would not be ill and an alcoholic-in-training. After Edmund is diagnosed with consumption, the family must decide on which sanitarium to send him to. Mary and Jamie try to say that Edmund’s consumption is due to the previous sanitariums that Edmund’s cheap father Tyrone decided upon. However, Tyrone’s being cheap is not to blame for Edmund’s illness, his mother is.Mary Tyrone brings about the suffering of her sons and husband through her own morphine addiction. Her addiction contributes immensely to Tyrone’s and Jamie’s alcoholism as well as Edmund’s illness. Their sufferings allow for this play to be a tragedy and for the reader to establish the theme that family-dynamics can hold us back if someone cannot take personal responsibility and move on. Mary Tyrone is a tragic figure in the tragedy A Long Day’s Journey into Night who functions as an instrument of the suffering of others.
