Major General Winfield Scott Hancock - Biography

Significant General Winfield Scott Hancock - Biography Winfield Scott Hancock - Early Life Career: Winfield Scott Hancock and his indistinguishable twin, Hilary Baker Hancock, were conceived February 14, 1824 at Montgomery Square, PA, only northwest of Philadelphia. The child of teacher, and later legal counselor, Benjamin Franklin Hancock, he was named for noted War of 1812 administrator Winfield Scott. Taught locally, Hancock got an arrangement to West Point in 1840 with the guide of Congressman Joseph Fornance. A person on foot understudy, Hancock graduated in 1844 positioned eighteenth in a class of 25. This scholastic execution earned him a task to the infantry and was dispatched as a brevet second lieutenant. Winfield Scott Hancock - In Mexico: Requested to join the sixth US Infantry, Hancock saw obligation in the Red River Valley. With the episode of the Mexican-American War in 1846, he got requests to direct enlisting endeavors in Kentucky. Effectively satisfying his task, he consistently mentioned consent to join his unit at the front. This was conceded and he rejoined the sixth Infantry at Puebla, Mexico in July 1847. Walking as a major aspect of his namesakes armed force, Hancock initially observed battle at Contreras and Churubusco in late August. Separating himself, he earned a brevet advancement to first lieutenant. Injured in the knee during the last activity, he had the option to lead his men during the Battle of Molino del Rey on September 8 however before long was overwhelmed by fever. This kept him from participating in the Battle of Chapultepec and catch of Mexico City. Recouping, Hancock stayed in Mexico with his regiment until the marking of the Treaty of Guadalupe Hidalgo in mid 1848. With the finish of the contention, Hancock came back to the United States and saw peacetime obligation at Fort Snelling, MN and St. Louis, MO. While in St. Louis, he met and wedded Almira Russell (m. January 24, 1850). Winfield Scott Hancock - Antebellum Service: Elevated to commander in 1855, he got requests to fill in as the officer at Fort Myers, FL. In this job he upheld US Army activities during the Third Seminole War, however didn't participate in the battling. As activities slowed down in Florida, Hancock was moved to Fort Leavenworth, KS where he helped in battling factional battling during the Bleeding Kansas emergency. After a concise period in Utah, Hancock was requested to southern California in November 1858. Showing up there, he filled in as collaborator officer under future Confederate authority Brigadier General Albert Sidney Johnston. Winfield Scott Hancock - The Civil War: An admitted Democrat, Hancock got to know numerous Southern officials while in California, including Captain Lewis A. Armistead of Virginia. Despite the fact that he didn't at first help the Republican strategies of recently chose President Abraham Lincoln, Hancock stayed with the Union Army toward the start of the Civil War as he felt that the Union ought to be saved. Saying farewell to his southern companions as they left to join the Confederate Army, Hancock voyaged east and at first was given officer obligations in Washington, DC. Winfield Scott Hancock - A Rising Star: This task was brief as he was elevated to brigadier general of volunteers on September 23, 1861. Appointed to the recently shaped Army of the Potomac, he got order of a unit in Brigadier General William F. Baldy Smiths division. Moving south in the spring of 1862, Hancock saw administration during Major General George B. McClellans Peninsula Campaign. A forceful and dynamic officer, Hancock mounted a basic counterattack during the Battle of Williamsburg on May 5. Despite the fact that McClellan neglected to benefit from Hancocks achievement, the Union administrator educated Washington that Hancock was heavenly today. Taken advantage of by the press, this statement earned Hancock his epithet Hancock the Superb. In the wake of participating in the Union annihilations during the Seven Days Battles that mid year, Hancock next observed activity at the Battle of Antietam on September 17. Compelled to assume responsibility for the division after the injuring Major General Israel B. Richardson, he supervised a portion of the battling along the Bloody Lane. In spite of the fact that his men wished to assault, Hancock held his situation because of requests from McClellan. Elevated to significant general on November 29, he drove the First Division, II Corps against Maryes Heights at the Battle of Fredericksburg. Winfield Scott Hancock - At Gettysburg: The accompanying spring, Hancocks division helped spread the withdrawal of the military after Major General Joseph Hookers rout at the Battle of Chancellorsville. In the wake of the fight, the II Corps leader, Major General Darius Couch, left the military in dissent of Hookers activities. Thus, Hancock was raised to lead II Corps on May 22, 1863. Moving north with the military in quest for General Robert E. Dregs Army of Northern Virginia, Hancock was called without hesitation on July 1 with the opening of the Battle of Gettysburg. At the point when Major General John Reynolds was murdered right off the bat in the battling, new armed force authority Major General George G. Meade sent Hancock ahead to Gettysburg to assume responsibility for the circumstance on the field. Showing up, he assumed responsibility for Union powers after a short quarrel with the more senior Major General Oliver O. Howard. Attesting his requests from Meade, he settled on the choice to battle at Gettysburg and composed Union barriers around Cemetery Hill. Assuaged by Meade that night, Hancocks II Corps expected a situation on Cemetery Ridge in the focal point of the Union line. The following day, with both Union flanks enduring an onslaught, Hancock dispatched II Corps units to help in the resistance. On July 3, Hancocks position was the focal point of Picketts Charge (Longstreets Assault). During the gunnery siege that went before the Confederate assault, Hancock boldly rode along his lines empowering his men. Over the span of the resulting assault, Hancock was injured in the thigh and his old buddy Lewis Armistead was mortally injured when his unit was turned around by II Corps. Bounding the injury, Hancock stayed on the field for the remainder of the battling. Winfield Scott Hancock - Later War: Despite the fact that he generally recuperated over the winter, the injury tormented him for the rest of the contention. Coming back to the Army of the Potomac in the spring of 1864, he participated in Lieutenant General Ulysses S. Awards Overland Campaign seeing activity at Wilderness, Spotsylvania, and Cold Harbor. Showing up at Petersburg in June, Hancock botched a key chance to take the city when he conceded to Baldy Smith, whose men had been battling in the zone throughout the day, and didn't quickly attack the Confederate lines. During the Siege of Petersburg, Hancocks men participated in various tasks remembering battling at Deep Bottom for late July. On August 25, he was beaten gravely at Reams Station, however recouped to win the Battle of Boydton Plank Road in October. Tormented by his Gettysburg injury, Hancock had to provide up field order the next month and traveled through a progression of formal, selecting, and regulatory posts for the rest of the war. Winfield Scott Hancock - Presidential Candidate: In the wake of regulating the execution of the Lincoln death plotters in July 1865, Hancock quickly told US Army powers on the Plains before President Andrew Johnson guided him to direct Reconstruction in the fifth Military District. As a Democrat, he followed a gentler line with respect to the South than his Republican partners hoisting his status in the gathering. With the appointment of Grant (a Republican) in 1868, Hancock was moved to the Department of Dakota and Department of the Atlantic with an end goal to get him far from the South. In 1880, Hancock was chosen by the Democrats to run for president. Facing James A. Garfield, he barely lost with the famous vote being the nearest ever (4,454,416-4,444,952). Following the destruction, he came back to his military task. Hancock kicked the bucket at New York on February 9, 1886 and was covered at Montgomery Cemetery in close Norristown, PA.

Expansion and contraction of matter Essay

Warm Expansion and Contraction The majority of the issues, without certain special cases, grow with the expanding temperature. At the point when you offer warmth to issues; speed of its particles increment and separation between them likewise increment which brings about the expansion of the volumes of issues. All developments happens in volume of the substance be that as it may, here and there a portion of the elements of them grow more concerning others. For this situation we disregard the less extended ones and accept extension like straight development in long materials. In addition, we accept the extension of plate as territory development lastly we take the extension in three measurements as volume development. warm extension Converse of the extension is called withdrawal, for the most part when matters lost warmth and their temperatures decline they contract. Presently we will realize which elements impact development. In the event that the underlying volumes, territories or lengths of the issues are large enough their extensions with a similar temperature are likewise enormous. At the end of the day, extension or compression is straightly corresponding to the underlying volume of the issue. Various issues have diverse nuclear structure, therefore separates between the molecules are likewise extraordinary. They give various responses to a similar measure of temperature changes. Along these lines, another factor affecting development is kind of issue. Last factor that influences extension is the measure of progress in temperature. Bigger the adjustment in temperature brings about bigger the adjustment in the volume of issue. We get following recipe from the clarifications given previously; ∆V=V0.ÃŽ ±. ∆T Where; ∆V is the adjustment in the volume, ÃŽ ± is the coefficient of warm extension and ∆T is the adjustment in the temperature of the issue. ÃŽ ±= Coefficient of warm development is equivalent to the adjustment in the volume of a unit of mass under 10C change in temperature. Development in Solid Matters We will analyze this subject under three title, direct development, territory extension and volume extension. Direct Expansion: Picture given underneath shows the straight development of metal bar. At the point when it is warmed, its length increments. straight development Our recipe for direct development is; ∆L=L0.ÃŽ ±. ∆T Where; ∆L is the measure of progress in the length of the pole, L0 is the underlying length of the street, ÃŽ ± is the coefficient of direct development and ∆T is the adjustment in the temperature of the issue. Model: There are three same metal bars having same length and thickness. On the off chance that the temperatures of them are given like; T, 2T and 3T discover the relations of conclusive lengths of the poles. (Bars are in contact) We locate the last temperatures of the framework by the equation; Tfinal=T1+T2+T3/3=6T/3=2T Since the temperature of the primary pole increment, its last length additionally increments. Temperature of the subsequent bar remains same, along these lines there won’t be change in the length of this bar. At last, temperature of the third bar diminishes, hence its agreement and last length of it diminishes as for starting length. Accordingly connection of the last lengths of the poles; L1>L2>L3 Zone Expansion: When plate given beneath is warmed, it grows in two measurements X and Y. We discover the territory development with the given recipe; ∆S=S0.2ÃŽ ±. ∆T Where; ∆S is the measure of progress in the region of the plate, S0 is the underlying territory of the plate, 2î ± is the coefficient of region extension and ∆T is the adjustment in the temperature of the issue. territory extension Model: We cut a roundabout piece from the rectangular plate. Which ones of the procedures given beneath can help us in going through the roundabout piece from the gap? extension model I. Expanding the temperatures of rectangular plate and round piece II. Diminishing the temperature of the round piece III. Diminishing the temperatures of the rectangular plate and round piece I. In the event that we increment the temperatures of the plate and round piece, extension of the opening and the roundabout piece will be the equivalent. In this way, thisâ option can support us. II. In the event that we decline the temperature of the round piece, it agreements and gap increases than the piece. This alternative can likewise support us. III. On the off chance that we decline the temperatures of the plate and round piece, gap and roundabout piece contract in same size. This procedure can likewise support us. Volume Expansion: If the articles grow in volume with the picked up heat, we call this volume development and discover it with the accompanying recipe; ∆V=V0.3ÃŽ ±. ∆T Where; ∆V is the measure of progress in the volume of the 3D square, V0 is the underlying volume of the solid shape, 3î ± is the coefficient of volume development and ∆T is the adjustment in the temperature of the issue. volume development Warmth Temperature and Thermal Expansion Exams and Solutions Phase Transition of Water< Prev Next > Heat Temperature and Expansion Cheat Sheet Tags:area expansioncalculations of warm expansionlinear expansionsamples of warm expansionthermal contractionthermal development and contractionvolume extension

Horror Of Rwandan Genocide - Free Essay Example

Rwandan Genocide Genocide is any act of violence that is committed intentionally aiming to kill and destroy the existence of a specific group of people whether whole or partial. It is the most unwanted world we have in English dictionary. I do not feel okay pronouncing it because I know it is the term that has been destroying part of humanity. Concerning the Rwandan genocide. It is the worst genocide to have occurred in Africa. Rwandan do called it Tutsi genocide because it was mostly against the tribe of Tutsi. Hutu the majority group in the government took guns in their hands after hearing that their president died. Their president Juvenal Habyariman was shot down from the aero plane crash and so his people Hutu blamed Tutsi for that incident and they took guns and started massacre. Another cause of that genocide was the Rwandan independent in 1963. During that time Tutsi people faced a stiff discrimination from the Hutu side and the only thing they could do was to travel out to Uganda. Their flight to Uganda made Hutu to set trap on them and in 1994 the trap flamed. Another cause of the genocide was the civil war that took Tutsi to exile and after returning to their country in 1990. An agreement was signed by the president who was from Hutu tribe. After the civil war some of the Rwandan people still had grudges against others, these continues until 1994 when it multiplied into genocide. Some of the causes of the genocide date back to the colonial days, during the time the Rwanda was rule by outside powers they the Tutsi were treated as superior by the Belgians so these caused tensions. During the colonial days Tutsi was rewarded with a good education and economic power from Belgian but unfortunately by 1962 the power went to Hutu people and immediately they sought revenge which continued until 1994. I think the genocide could have been avoided if the tribes Hutu and Tutsi were united. If the Hutu tribe did not suspect Tutsi over the killing of the president, the genocide could not have occurred. It was also bad for the two communities to have lived all along sticking on the bad things that took place during the colonial days summing it up into what we called revenge. I said it this way because the massacre was the reference from what took place before. There was not clear parties who took part in resolving conflicts. People said that the genocide ended just because Tutsi rebels defeated the government. Paul Kagame was the leader of the rebel whose party was called Rwanda patriotic front (RPF). He fought a serious war with Hutu the government and he defeated them hence end of genocide. The war ended only in hundred days and later Hutu had a president from them Pasteur Bizimungu and Paul Kagame became vice president and he was the one in charge of the army. These too was not enough , Kagame and Bizimungu later fell out because the president was suspected of inciting ethic violence these made him to be jailed and immediately Paul Kagame took the throne and he has been the president since the turn of the new millennium.

Roman Architecture The Temple Of Apollo - 1211 Words

After the Etruscan’s rule of Italy, Rome adopted much of their culture, and as a result many aspects of their architecture. Because the Roman style of architecture had developed over many years, once they adopted their ways of building, they rarely changed it. A case in which the Romans used some Etruscan elements in their building is the Capitoline Temple in Rome. However, a very important exception of this is how they adopted greek elements that they liked into their style. Once the Romans came in contact with the Greeks, they used some of their components, but they always stayed true to their design. One instance in which this is shown, is the Temple of Apollo in Pompeii. It is a rectangular building with Doric columns surrounding the entire structure, as well as a large and intricate statue of Apollo, which are both hallmarks of Greek architecture. Unlike the Romans, the Greeks embellished the outside of their buildings rather than the inside. Roman temples often had ornam entation on the inside to make a spectacle for the public once they enter. An illustration of this is in the Pantheon. It is simple on the outside with a perimeter of Greek Corinthian columns, but on the inside, the immense dome with coffering and the intricately laid tiles on the floor make the inside breathtaking for all who enters. Because of this, Greek temples were approached by a corner in order not to ruin the facade of the temple.

With new technology scientists have come up with a way to insert mitochondrial DNA of a healthy egg to one that is genetically damaged or impaired. â€Å"Scientists have also recently reported a method of extracting defective mitochondria, the energy powerhouses of cells, from a woman s egg and replacing them with healthy mitochondria from a donor egg† (Ghose 2014). In 2015 there was the first reports of mitochondrial DNA transplant, â€Å"Three-parent babies† is a sensationalized term to describe a special form of in vitro fertilization, or I.V.F., that is better labeled mitochondrial transfer† (Malik 2015). This process is similar to in vitro fertilization where the child is created in the test tube, but is then fertilized egg injected with the healthy mitochondrial DNA (Malik 2015). The mitochondrial DNA is injected into the nucleus where the hope is that the healthy mitochondrial DNA will take over the unhealthy mitochondrial DNA (Malik 2015).

Only a small fraction of our total DNA makes us di Essay DNAfferent from gorillas, chimpanzees and other primates. An even smaller fraction makes one person different from the next. DNA Deoxyribonucleic acid and ribonucleic acid are two chemical substances involved in transmitting genetic information from parent to offspring. It was known early into the 20th century that chromosomes, the genetic material of cells, contained DNA. In 1944, Oswald T. Avery, Colin M. MacLeod, and Maclyn McCarty concluded that DNA was the basic genetic component of chromosomes. Later, RNA would be proven to regulate protein synthesis. DNA is the genetic material found in most viruses and in all cellular organisms. Some viruses do not have DNA, but contain RNA instead. Depending on the organism, most DNA is found within a single chromosome like bacteria, or in several chromosomes like most other living things. DNA can also be found outside of chromosomes. It can be found in cell organelles such as plasmids in bacteria, also in chloroplasts in plants, and mitochondria in plants and animals. All DNA molecules contain a set of linked units called nucleotides. Each nucleotide is composed of three things. The first is a sugar called deoxyribose. Attached to one end of the sugar is a phosphate group, and at the other is one of several nitrogenous bases. DNA contains four nitrogenous bases. The first two, adenine and guanine, are double-ringed purine compounds. The others, cytosine and thymine, are single-ringed pyrimidine compounds. Four types of DNA nucleotides can be formed, depending on which nitrogenous base is involved. The phosphate group of each nucleotide bonds with a carbon from the deoxyribose. This forms what is called a polynucleotide chain. James D. Watson and Francis Crick proved that most DNA consists of two polynucleotide chains that are twisted together into a coil, forming a double helix. Watson and Crick also discovered that in a double helix, the pairing between bases of the two chains is highly specific. Adenine is always linked to thymine by two hydrogen bonds, and guanine is always linked to cytosine by three hydrogen bonds. This is known as base pairing. The DNA of an organism provides two main functions. The first function is to provide for protein synthesis, allowing growth and development of the organism. The second function is to give all of its descendants its own protein-synthesizing information by replicating itself and providing each offspring with a copy. The information within the bases of DNA is called the genetic code. This specifies the sequence of amino acids in a protein. DNA does not act directly in the process of protein synthesis because it does not leave the nucleus, so a special ribonucleic acid is used as a messenger. The mRNA carries the genetic information from the DNA in the nucleus out to the ribosomes in the cytoplasm during transcription. This leads to the topic of replication. When DNA replicates, the two strands of the double helix separate From one another. While the strands separate, each nitrogenous base on each strand attracts its own complement, which as mentioned earlier, attaches with hydrogen bonds. As the bases are bonded an enzyme called DNA polymerase combines the phosphate of one nucleotide to the deoxyribose of the opposite nucleotide. This forms a new polynucleotide chain. The new DNA strand stays attached to the old one through the hydrogen bonds, and together they form a new DNA double helix molecule. As mentioned before, DNA molecules are involved in a process called protein synthesis. Without RNA, this process could not be completed. RNA is the genetic material of some viruses. RNA molecules are like DNA. They have a long chain of macromolecules made up of nucleotides.

There are four main nitrogenous bases found in RNA. There are the double-ringed purine compounds adenine and guanine, and there is the single-ringed pyrimidine compounds of uracil and cytosine. RNA replication is much like that of DNAs. In RNA synthesis, the molecule being copied is one of the two strands of a DNA molecule. So, the molecule being created is different from the molecule being copied. This is known as transcription. Transcription can be described as a process where information is transferred from DNA to RNA. All of this must happen so that messenger RNA can be created, the actual DNA cannot leave the nucleus. For transcription to take place, the RNA polymerase enzyme is needed first separate the two strands of the double helix, and then create an mRNA strand, the messenger. The newly formed mRNA will be a duplicate of one of the original two strands. This is assured through base pairing. When information is given from DNA to RNA, it comes coded. The origin of the code is directly related to The way the four nitrogenous bases are arranged in the DNA. It is important that DNA and RNA control protein synthesis. Proteins control both the cells movement and its structure. Proteins also direct production of lipids, carbohydrates, and nucleotides. DNA and RNA do not actually produce these proteins, but tell the cell what to make. For a cell to build a protein according to the DNAs request, a mRNA must first reach a ribosome. After this has occurred, translation can begin to take place. Chains of amino acids are constructed according to the information which has been carried by the mRNA. The ribosomes are able to translate the mRNAs information into a specific protein. This process is also dependent on another type of RNA called transfer RNA (tRNA). Cytoplasm contains all amino acids needed for protein construction. The tRNA must bring the correct amino acids to the mRNA so they can be aligned in the right order by the ribosomes. For protein synthesis to begin, the two parts of a ribosome must secure itself to a mRNA molecule.

Fleshiness is a status of a individual that has extra organic structure weight in the signifier of fat. Harmonizing to most of the surveies. an corpulent individual has a BMI of 25 or supra.

Due to discovery of engineering. there are things or appliances that made our life easier and faster and more convenient because they do the work for us. Peoples became lazy ; they have less exercising. less activity at work. Most of the clip people relied on fast nutrient bringings and about everyone seems to be acquiring heavier. In the article written by Arielle Bethlehem entitledObesity and Healthshe said that fast nutrient is frequently deemed the individual biggest ground Americans are overweight. † Environment can besides lend to fleshiness. The sort of communities an single belon gs. places. and workplaces can all act upon people’s wellness determinations. One’s calorie ingestion can find to his hereafter weight. Due to altering environment particularly in US. eating wonts and nutrient options has been broadened. Last there are some drugs that lead to deriving weight like steroids and improper usage of these drugs can do fleshiness. Some of the unwellnesss can besides lend to fleshiness. â€Å"Are medical research workers overemphasising the wellness hazards associated with being overweight† ?This is the subject I have chosen from the CQ Researchers Pro/Con nexus â€Å"Given that lasting weight loss is elusive for most fat people. the issue of fat and wellness is irrelevant. The lone true option available is to be every bit healthy as you can. regardless of your weight. ( Often times the wellness issue serves as a fume screen to warrant denying fat people their civil rights. The premise that fat people are unhealthy is frequently used to support favoritism in employment. educational chances. and lodging and acceptance privileges. Health issues should neer supplant one’s civil rights. ) The National Association to Advance Fat Acceptance agreed to this statement. From â€Å"Dispelling Common Myths about Fat Persons. † adapted from stuff developed by Carrie Hemmenway. The cons represented by Michael Fumento said that â€Å"Since 1959. informations began to corroborate earlier intuitions that fleshiness is harmful. That’s when the first Build and Blood Pressure Study appeared. [ It ] found that. . . the fatter the individual. the more likely the individual was to decease prematurely. By the clip one reached 30 per centum over recommended weight. there was a 42 per centum greater opportunity of deceasing early. † I agree with National Association to Advance Fat Acceptance. Sing fat people is merely an ordinary scene to my mundane life and every clip that happens. I ever think that it is merely a affair of pick. They choose to be corpulent. However it can non be denied besides that they are being criticized and discriminated. Our society sets the criterions of how people should look like. The intension of being sexy is the skinny-modeled typed for a miss and a hunk-type with perfect for male childs. Subjects about. diet. fittingness. fleshiness. weight control and the likes which are ever discussed in magazines are being overused now. I’ve known so many fat people who have made legion attempts and exhausted 1000s of dollars throughout their lives merely to lose weight and each clip regained the lost lbs plus a few more. The world is that fleshiness is like a â€Å"yo-yo phenomenon† . It is truly difficult to accomplish a lasting weight loss. If this happen to person who is seekin g to lose weight adequate times they will be dying at the chance of losing weight for fright of deriving back more than you lose. Peoples who experienced things like this will be disappointed and go hopeless so they will halt and merely make what they want and this will truly do them genuinely happy. Though Michael Fumento is right of stating that fleshiness is damaging to wellness but a individual is the 1 doing a pick for their ain lives. They should non be pressured on what sort of form of organic structure they should possess. â€Å"The difference [ between fat and thin people ] is non between the weak and the strong or the unprompted and the abstemious. but between internal ( rather likely innate ) controls that are set otherwise in different people† quoted by Kelly D. Brownell in her book. ( TheDieters Dilemma: Eating Less and Weighing More. 1982 Fleshiness is a wellness is a job. That is a fact but anybody can get the better of it. It should get down of holding a end to achieve and believing in 1s. ego that we can accomplish our ends.

buy custom Reinforcement Theory of B. F. Skinner essay

buy custom Reinforcement Theory of B. F. Skinner essay Principles of the Theory Reinforcement theory of B. F. Skinner enhances and proves principles and achievements of behaviorism. According to its followers, free will and other spiritual characteristics cannot be objects of scientific research because of the hidden and unobserved nature of those phenomena (Schultz Schultz, 2013). B. F. Skinner believed that people were only machines subject to predictions and control. He claimed that the science of human behavior was not different from any other natural evidence-based science (Skinner, 2011). His theory is most relevant to the issue of personality development. Studying personality in terms of behaviorism, B. F. Skinner emphasized the importance of the past human experience and the unique nature of human abilities. Like many other theorists, B. F. Skinner believed that understanding of human nature could come through observation of the behavior of a human body in interaction with the environment (Skinner, 2011). Accordingly, this interaction was the focus of numerous carefully set experimental studies. The principle of reinforcement became the primary concept in the Skinners studies (Coon Mitterer, 2008). This revealed the theory of operant reinforcement. B. F. Skinner distinguished two approaches to the study of a personality. He differentiated standpoints of innate and operant behavior (Skinner, 2011). The first reflective type of behavior implied characteristic reaction caused by a known stimulus. Events following the reaction determined operant behavior. For example, withdrawal of a hand touching a hot object was an example of innate reactions, while cycling and playing musical instruments were examples of the operant reinforcement. Speed with which people could acquire and fix the operant behavior depended on the rule and mode of reinforcement. B. F. Skinner investigated changes of reaction, learning, and behavior modifications. Reinforcement has become one of the conditioning principles (Coon Mitterer, 2008). Starting from early childhood, human behavior is subject to outward reactions and support. People acquire types of behavio supported by the perception of pleasure and joy. There are primary reinforcements, such as food or elimination of pain, and other stimuli such as smile, adult attention, approval, or praise (Schultz Schultz, 2013). Operant conditioning relies mainly on positive reinforcement. Nevertheless, Skinner emphasizes importance of a negative reinforcement, which leads to the extinction of an undesired response. It can be physical punishment, moral influence, or psychological pressure. Unpleasant stimulus in the punishment should be a reaction, reducing the likelihood that the response will appear again (Skinner, 2011). How Does the Theory Address Differences in Gender and Culture? Gender is a set of representations of male and female social roles and types of behavior. It is a cultural mask of sex. Three basic gender approaches are the theory of social construction of gender, a stratification category, and a cultural metaphor. The theory of the social construction of gender is an organized structure of interrelations between women and men, as well as being one of the basic institutions of the society. It reveals two postulates. The first is the assumption that gender is a product of socialization, labor system of gender roles, family, and the media. The second explains the concept in terms of gender identity, adoption of some given society norms, and sub-alignment for them (Coon Mitterer, 2008). It means traditions in clothing, appearance, demeanor, and leadership qualities. The concept of gender reflects creation of cultural and social differences between boys and girls, men and women that are not natural, intrinsic, or biological. Gender as a stratification category is a structure or process among a number of other stratification categories such as class, race, and age. As a cultural metaphor, the concept serves as a cultural symbol and a cultural-forming factor. Social learning theory, which goes back to the ideas of behaviorism, explores major concepts, such as learning and positive and negative reinforcement model of parental behavior. It emphasizes influence of the microenvironment and social norms on external sex-role behavior and focuses on a typical sex behavior. Parents and surrounding peeople teach boys and girls to behave according to patterns of their gender and condemn when they adopt behavior of the opposite sex. Parents tend to blame the lack of independence in boys and girls, but they are allowed to be dependent. As a result, boys learn that one should rely on his achievements to gain self-respect and self-esteem, while girls upbringing depends on treatment by and attitude of others (Schultz Schultz, 2013). The diversity of social characteristics of people worldwide reveals that biological sex cannot be an explanation of differences in social roles existing in different societies. The concept of gender denies the fact that people depend on their belonging to males or females. Neither biological sex nor socio-cultural norms ultimately determine behaviors, activities, and careers of women and men. In terms of the reinforcement theory, it is possible and even necessary to modify and construct equal gender roles and types of behavior. Does the Theory Present a Comprehensive Explanation of How Personality Develops? Behaviorism is known as the psychology without a mind. This turnover assumes that the mind is identical to consciousness. They compare mental qualities of people to operations of some devices. It has changed the perception of those qualities. A real contribution to the new direction is the dramatic expansion of the field of psychology. It now includes availability of an external objective observation. Behaviorists have changed the scheme of psychological experiments held them mainly on animals like white rats. Experimental devices are different types of labyrinths and problem boxes. While running them, animals have learned to find their way out of those boxes (Schultz Schultz, 2013). Themes of learning and acquisition of skills by trial and error have become central in the theory of reinforcement. There have appeared many experimental data on determinants of behavior modification. The reinforcement theory has changed the conception of laws that govern behavior of living things, including humans. The last point has appeared in experiments with big white rats. People appear to be the same, finding their way in the maze of life (Schultz Schultz, 2013). Buy custom Reinforcement Theory of B. F. Skinner essay

An Analysis Of The Fast Food Industry

An Analysis Of The Fast Food Industry Fast food is a food that prepared and served quickly at a fast food restaurant or a shop. It is served usually in a carton or bags in order to minimize cost. Most fast food outlets often provide take away or take out foods in addition to sit down services. Fast food is quite popular product now days. With the development of economic and society, the fast food Menu which was used to be quite limited became variable. Moreover, it’s difficult to provide a qualitative distinction because fast foods have a really big range. The best way to distinguish fast foods is to use formal characteristics: Time required – those who eat fast foods do not want to spend a lot of time on selecting and eating, and if necessary will eat standing or walking, on the bus, park bench, or at work. Actually, although it is familiar to everyone’s life because we were purchasing, few people has focus on the operation module, marketing competition and influence of fast food industry. 1.2 Why I chose this topic ¼Ã… ¸ Fast food is a multi billion industry continuing to grow rapidly in these years. As a result, the competition between the industries was farce now. Fast food is often highly processed and prepared in an industrial fashion. With standard ingredient, methodical cooking and production methods, the competition of fast food was though service, taste, promotion and supply chain. Fast food was found at America firstly. Moreover it has big influence in American society and culture. The notion of fast food reflect American culture of in which the speed and efficiency are highly priced. Moreover, these years, American fast food is facing new challenges both from economic and society. Fast food, in many ways, is the story of contemporary America .Therefore; this report would focus on American market of fast food industry. 2. PEST Pest analysis is a method to describes a structure of macro-environment factors of a business by examining related political ,economic, soc ial and technological .it is kind of market research which give some important elements that the company have to take into consideration when making strategic decisions. 2.1 Background There are three general categories of fast food businesses: 1,Self-service restaurants with a fast-food palette like McDonalds, Burger King, Pizza Hut, etc. this kind of food was favorable is because it provide a place for customers meeting friends. 2, Take-out restaurants which sell ready-to-eat foods and beverages which were favorable by working people are also popular. 3, Hot-dog stands and snack stands with counters or a pair of stand-up tables. The big advantage of these kind restaurants is convenient and cheap. The concept of fast food pops up during 1920s.In 1921, White castle was found in Kansas of America. At that time ,most people consider the burger sold there was not as good and cheap ,so White Castles’s decided to change the public perception of hamburgers and built their restauran ts for show customers how the food being prepared.The McDonald brothers opened their redesigned restaurant in 1948. After that, fast food developed quickly during the economy and society rapidly changing period. (Warsi&Nisa, 2005)

Applying The Western Model Of Government On Countries Around The World Essay

Applying The Western Model Of Government On Countries Around The World - Essay Example If in the West the non-fulfillment of such standards are interpreted to basically indicate government failure, applying the same Western model in assessing another country's government would also require the same standards to be met in order for that government to be deemed successful. In the Western model of Democracy, for example, due process of law, respect for human rights and individual liberty, and the general population's participation in the democratic electoral process are among the standards that have thus far been raised by the Western school of thought to measure a country's level of democracy. When non-Western Democratic countries and governments, therefore, fail to provide adequate evidence that these specific standards are being met, these countries risk immediately being condemned by the global society as undemocratic. Organizations and individuals insisting on the application of Western models of government and the implementation of Westerns standards deduced from such models have thus been quick to condemn any and each country that have failed to meet these Western standards. Repressive regimes that fail to meet Western standards of Democracy, and who have a history, for example, of human rights violations, staggering judicial systems, and a weak electoral process, have thus been pressured in numerous instances to reform and meet these Western standards in order to gain the acceptance and approval of the dominant West. To be sure, the notion that a universal set of standards can be deduced from Western models of government and applied indiscriminately to all countries in the World, rests on some very thin assumptions-that there is only one path towards the development of a specific form of government, and that a country's progress down this path is but a naturally occurring process, one that is not influenced by internal and external factors. We can see these assumptions more clearly for what they are if we investigate the global movement towards Democracy. The application of a Western model of Democracy for all countries, for example, presumes that a country's progress towards democracy is a naturally occurring phenomenon, one that is dictated upon by a single process and occurs naturally without regard for a country's socio-political status nor influenced by any external and internal forces. Basically, this means, that countries would generally develop into democracies as they progress regardless of any internal and external pressure or movement. This has largely been disproved by numerous studies, most notably, an examination conducted in 1996 which showed that 58 out of the 61 democratic countries that were studied became democratic unnaturally and that democratic progress was as a matter of fact induced by way of economic sanctions and conditional aid that demanded for democratic legislation. (Whitehead, 1996) With today's governments leaning decisively towards Democracy and democratic forms of governance, the implementation of a universal model of democracy-one that is produced and upheld by the dominant West-presumes that for a country to successfully implement and uphold a democratic form of

Brain and spine Essay Example | Topics and Well Written Essays - 3000 words

Brain and spine - Essay Example Thus, it is oxygenated in lungs, and de-oxygenated once it passes through tissues (Guyton and Hall, 2006). Because of its liquid nature, it is able to seep through spaces once a vascular injury occurs. We usually see it as bruising of the skin, when trauma causes breakage in the thin-walled capillaries in the dermis. The bruising then recedes with time, and the skin goes back to its previous appearance as if nothing happened. The same may not be applicable to other organs, more notably the brain. Although there is no obvious bruising similar to that seen on the skin, brain hemorrhages present with more serious signs of paralysis or changes in the sensorium, as caused by the ischemia and neuronal death of the area in the brain that should have been perfused by the injured vessel. Soon, ischemia of some brain tissue results to irreversible neurologic dysfunction. Prompt management is thus needed before neurologic defects become permanent (Kumar et al., 2010). The age of hemorrhage is important because it determines the management of intracranial hemorrhage, as will be discussed later. The stages of hematoma are based on the form of hemoglobin in RBCs. Initially, during the hyper-acute phase or hours after the development of the lesion, hematoma is made up of a liquid suspension of intact RBCs containing oxy- or deoxy-hemoglobin. If the blood came from an arterial source, which is the case in most non-traumatic etiologies such as aneurysm, approximately 95% of hemoglobin molecules are oxygenated. Later, water is resorbed by the brain tissue, resulting to a solidified aggregation of RBCs. As the blood ages further, the hemoglobin denatures from oxy- or deoxy- to met-hemoglobin. This transformation is dependent on the oxidation of ferrous (Fe+2) heme iron contained by oxy- and deoxyhemoglobin to ferric (Fe+3) state, turning the protein into

Careers in Acoustic and Audio Equipment Design :: Essays Papers

Careers in Acoustic and Audio Equipment Design Audio engineers have an interesting combination of character traits. On the one hand they tend to love music and want to have a hand in creating it. On the other hand they are also lovers of technology and ‘cool gear’. Along with an interest in technology usually comes an interest in understanding how it works – a desire to master the technology. With some people also comes a desire to go beyond the latest gear and ‘do it better’. They have a desire to create new technology which will provide the ultimate listening / processing / recording / etc experience. This paper will explore career opportunities that exist for those people. There are many different areas of audio related design in which to pursue a career. To illustrate, consider the typical live music concert. First of all, the performance venue needs to be acoustically designed to provide a good listening environment. Each of the performers’ instruments is designed and depending on the instrument the design could have involved acoustic as well as electronic knowledge. Sound reinforcement for the concert involves a myriad of equipment each with it’s own design criteria. Finally, if the concert is to be recorded and produced on a CD, all the recording equipment would need to be designed as well as the studio that it is used in. To design something is to conceive and invent. It is the art of creating the arrangement of parts or details of something. Furthermore, the point of designing something is to meet a need or to solve a defined problem. Each of the different design tasks involved in the concert scenario requires a different type of design expertise. There are basically four areas of design involved - acoustics, electronics, industrial design and mechanical design. Each of these areas overlaps with the other somewhat. Furthermore, each of these areas has an ‘art’ side and a ‘science’ side to them. Acoustic designers create the plan for performance spaces like concert halls as well as recording studios, and any other space that needs to provide a quality listening environment. They may also be involved in specifying equipment to provide sound reinforcement in the venue. Some acoustic design firms offer a full range of services, which may include site analysis, interior design, lighting, power and HVAC systems, wire management, budgeting, construction administration, and acoustic tuning (Droney).

The Journey of Two American Girls

The Journey of Two American Girls Laura Logan ENG125: Introduction to Literature (AFG1301A) Instructor: Carla  McGill February 4, 2013 How can an African American and a Hispanic girls be treated different when they are the same type of person? I chose the theme of race and ethnicity when I selected the poems â€Å"What It’s Like to Be a Black Girl† by Patricia Smith and â€Å"Child of the Americas† by Aurora Levin Morales. I am a Hispanic person with an African ancestry. I speak fluent Spanish and English and have experience life from both sides of the continent.The poems show how African American and Hispanics American girls lives were affected based on their race and ethnicity. The life of the African American girl life was affected because of her race and racism; while the life of the Hispanic American girl life was (not) affected because of her ethnicity. While both the African American and Hispanic American girls were born on American soil, racism affected the African American girl’s way she lived her life while ethnicity (heritage) played a major role in Hispanic American girl’s life.The poem â€Å"What It’s Like to Be a Black Girl† is about a nine year old African American girl who life was immensely affected by racism and the fact that she was a girl did not help her either. The thing that I notice was missing is where is the girl’s parents during the time she was growing up; maybe it was the author intent not to mention the girl’s parents. Growing up is tough enough as a black girl, you add the absence of parents and throw in racism, this girl does not have a chance to live a successful life. According to the American Heritage College Dictionary, racism has two meanings.First, racism is, â€Å"The belief that race accounts for differences in human character or ability and that a particular race is superior to others. † Second, racism is, â€Å"Discrimination or prejudice based on race. † The African American girl health was effected by racism, she was conditioned to be ashamed of her skin color, the texture of her hair and ethnicity. In her mind she think the only way the coccasion people will except her is if she look like them. According to Bhui, (2002) Racism is a fundamental cause of disparities in health.Its myriad effects and links to other forms of social stratification lead to it being both obvious and masked. Its boundaries are indistinct because it is internal as well as external, individual as well as ecological, and shunned while being an integral part of dominant culture ideology. Its investigation is important and yet part of the spider’s web that traps the best thinkers of ethnic minorities in contemplation instead of action and this brings us to the final paradox, understanding racism is a prerequisite of beating it (p. 3). I get the feeling that the black girl not only felt that at nine she was not finished, but perhaps she coul d into a different person other than the person she was then. The African American girl definitely had mental heath issues, she wanted white skin and blue eyes, something that was accepting of the culture of that time. According to Smith (1991) â€Å"It’s being 9 years old and feeling like you’re not finished,† writes Smith, â€Å"like your edges are wild, like there’s something, everything, wrong. † (line, 4).According to Smith (1991) the â€Å"black girl† she refers to in her poem is feeling the awkwardness of her newly changing body and the hope of something different and maybe better to come (p 283). Some people would say that the African American girl understands her body, but I would say that she is not ready for her body changes perhaps because of who she is or want to be and that is to look like the other girls in the society in which she lives. The life of the Hispanic girl in the â€Å"Child of the Americas† is so different from that of the black girl in the â€Å"What It’s Like to Be a Black Girl†.I stated that I have live on both sides of the Americas, and like the Hispanic girl in â€Å"Child of the Americas† by Aurora Levin Morales, According to Dictionary. com ethnicity is ethnic  traits, background, allegiance, or association; relating to or characteristic of a human group having racial, religious, linguistic, and certain other traits in common; relating to the classification of mankind into groups, especially on the basis of racial characteristics; denoting or deriving from the cultural traditions of a group of people.I must say that I have experience little to know racism. In the Hispanic society we are free mentally and physically to be want ever we want to be without restrictions being place on us girls. The Hispanic girl understand who she is and where she comes from. The one thing I notice about the two poems is that the author in this poem mention the girl’s m other and grandparents, which indicates that there is a support system in place to deal with life situation. The Hispanic girl unlike the African American girl was proud of her body and her light-skinned mestiza.Morales (1986) states that I am a child of the Americas, a light-skinned mestiza of the Caribbean, a child of many diaspora, born into this continent at a crossroads. I am a U. S. Puerto Rican Jew, a product of the ghettos of New York I have never known (p. 278). (Morales, 1) shows that this girl knows who she is and accepts that she is different than what she may see everyday. She is proud of her Puerto Rican heritage, proud to be of multi-racial descent, proud to be from the islands.She knows where she comes from and where she has is going. In â€Å"Child of the America’s†, the girl proudly states she is, â€Å"a light-skinned mestiza of the Caribbean†. (Morales, 2) The girl in this poem lets us know from the beginning that she is a girl of mixed race. She is strong and confident in her abilities. She enjoys life and appears to be well educated and well versed. Her social class could be middle class to wealthy with parents that worked their way out of poverty. â€Å"A product of the ghettos of New York I have never known†. Morales, 5)    â€Å"I speak English with passion: it's the tongue of my consciousness, a flashing knife blade of cristal, my tool, my craft†. (Morales, 7, 8) I remember when my daughter was in elementary school and she took a knife to school for protection and she was the tallest student in the school. Patrica Smith, the author of the poem â€Å"What’s it like to be a Black Girl† discusses the challenges the African American girl has with identifying the changes her body is going through as she is growing up. The African American irl does not appear to know what is going on, or perhap just do not want to face the future because of who she is, the color of her skin, the texture of her hair and the color of her eyes. Smith (1991) states that â€Å"It’s finding a space between your legs, a disturbance at your chest, and not knowing what to do with the whistles, it’s jumping double dutch until your legs pop, it’s sweat and Vaseline and bullets, it’s growing tall and wearing a lot of white, it’s smelling blood in your breakfast. † (p. 278).According to Myers (2002) African American women noted lower satisfaction with professional lives, differential and negative treatment from colleagues, and greater feelings of isolation on campus. Such isolation carries with it important implications: Literature shows that the rate of promotion and tenure among African American women is slower than that of African American men and white women. Isolation and lack of effective mentoring processes are direct influences in these low promotion and tenure rates as well as low retention rates among African American women in academia (Williams- Green and Singh, 1995).The state of mine she was in due to racism and her lack of support from her family especially a father figure, made it very hard for her to be a good judge character when it came to her selecting or being selected by the male persuasion. The Hispanic girls life is total contrary to the African American girl’s life. My young life was very similar to the Hispanic girl. She was very aware of her growing up and her body changes. She had a support around her as she was growing up and she was deeply rooted in her heritage and proud to shake it and speak her mind when needed.It even sounds like the Hispanic girls even like literature as she like the singing of poetry. Morales (1986) indicated that Spanish is my flesh, Ripples from my tongue, lodges in my hips: the language of garlic and mangoes, the singing of poetry, the flying gestures of my hands. I am of Latinoamerica, rooted in the history of my continent: I speak from that body p. 278). The author kind o f implies that the Hispanic girls enjoys having a good time dancing and living the Latinoamerica life style.The poem â€Å"What It’s Like to Be a Black Girl† the girl is continually getting older and bigger and changing her clothing, to wear white clothing trying to look like the society who is showing racism toward her. She want to wear white like a new bride, which symbolize purety. She has seen a lot of racism in her life and based on the fact she want to be Caucasian or at least look like them. She only see African American in a negative way. The mood of the black girl is somber and sad because every phase in her life there is know one for her to talk to or lift her spirits.The Hispanic girl in the poem â€Å"Child of the Americas† is happy about where she came from, like me, she is probably bilingual and loves the fact that she is Puerto Rican and unlike most Hispanics she is Jew. Accoring to Morales (1986) the girl is a U. S. Puerto Rican Jew, a product of the ghettos of New York I have never known. An immigrant and the daughter and granddaughter of immigrants. I speak English with passion: it’s the tongue of my consciousness (p. 278). The Hispanic girl can relate to more than one culture and have multiple races to identify with; she has many races and loves them all.The African American life will aways be in termoil and does not know how to resist a man when they are not right for her. The first man that reaches out to her, she just gave in to him without any resistance. On the other hand, the Hispanic girl life was all line up for, like most Hispanic women she was determined in life and had the will power to resistance a bad situation and move away from it. The Hispanic girl was very secure about who she was and what she wanted to become and had the support of her family, unlike the black girl who was not sure of who she was and how she was going to get there.The poems were completely opposite when it came to the style as th ey sent different messages to the reader. The style is the mood or attitude reflected in a literary work. The â€Å"What it’s like to be a black girl†, the style is that of confusion, uncertainty, and sadness. She doesn’t understand what’s happening to her body or just do not want to except it because of the racism she has face in her life and why she look like the people who are mistreating her because she does not have blonde hair and blue eyes.The style of â€Å"Child of the America’s is that of a proud heritage, love of self, and accepting who you are and proud to be what you are. She loves who she has become and where she comes from. She understand her body and uses it to her advantgage. The biggest difference I see in the two girls is that one had no family support and really know heritage to fall back on and the other had great support and how they saw themselves. in the way they perceive themselves. The black girl did not know that black i s beautiful and to be proud of your heritage and who you are.She is lacking role models that she can live or look up. Unfortunate she lived in an era where racism was allow to thrive, which lead to discrimination because of the color of her skin. The poem â€Å"Child of the Americas† by Aurora Levins Morales is about social diversity. It is about a person like myself coming from Central America. I was born in Panama, where we did not experience racism until I came to the United States. According to Morales (1) I am a child of the Americas, a light-skinned mestiza of the Caribbean, a child of many diaspora, born into this continent at a crossroads.Like the character in the poem I to am the child of the Americas, except my skin in dark brown and I am proud of my Spanish heritage and teach it to my children. I have African in me, but I am not accepted as an African because I speak fluent Spanish and English. African American do not accept me as an African American because I spea k Spanish. Morales (18) also indicates that â€Å"I am new. History made me. My first language was spanglish. I was born at the crossroads and I am whole† (p. 278).Racism is a belief in racial superiority:  the belief that people of different races have different qualities and abilities, and that some races are inherently superior or inferior. Racism affected how minority girls were treated and the lack of a good quality education. It seperates us from our fellow man. Rather than trying to improve our society or our nation we are spend more time aruging with or neighbors who are of a different ethic background. Racism divides us instead of bringing us closer together. We then create cities seperated by race, and prefer to stay in our own city with fellow people of our race.The country becomes further divided, one group of people on one side and another group of people on the otherside. Prejudice is a irrational dislike of somebody:  an unfounded hatred, fear, or mistrust of a person or group, especially one of a particular religion, ethnicity, nationality, sexual preference, or social status. People had a preconceived notion about African American people which had a negative affect the girls of that culture. The African American girl experienced prejudice based on the fact of her being a person of color, not because of her actions.The theme in the poem â€Å"What it’s like to be a black girl†, is that of confusion, uncertainty, and sadness. The theme of â€Å"Child of the America’s is that of hope, loving your self for who you are.. The poem â€Å"Child of the America’s† did not display any racism or prejudice even though that is not the case for an minority girl in the middle nineteen hundreds in which I experience. The Hispanc girl was just the opposite, there were no boundaries place on her because of her skin color and what ever she dream she wanted to become she could of without prejudice.Her family taught he r to be proud of her Hispanic heritage, to be very prideful of the fact that she is bi-lingual and from the island of Puerto Rico. I was raise to very proud of where I am from and do not forget my family heritage. According to Morales this girl is proud of her Hispanic background and her religious affiliation (1 – 6) I am a child of The Americas, a light-skinned mestiza of the Caribbean, a child of many diaspora, born into this continent at a crossroads. I am a U. S.Puerto Rican Jew, a product of the ghettos of New York I have never known (p. 278). The girl in the poem â€Å"Child of the America’s† proudly explain that Spanish is in her flesh as Morales (1986) states that In recognition of the Spanish influence and in credit of the land that used to be part of the America from which people of Spanish and American descent have intermingled and shared their culture. Spanish influences such as religion, tradition, and food are treasured by Latin Americans who are v ery proud of their heritage. They are Americans (n. p. Morales also indicated that the girl was proud of the other countries she was a part of to include Africa, Europe. We all know that soon that will be a minority of people from America because of it is a melting pot and their will be no typical American because Americans came from a melting pot of culture. Their multiple cultural heritage, tradition, and influences and there are a combination of people to form the American culture. The African American girl seem to be unaware of the changes her body was going through, perhaps because of her situation she was into.In the poem, â€Å"What’s it like to be a Black Girl†, Smith (8) talks about the things that are happening with the girl’s body, as she is developing. â€Å"It’s finding a space between your legs, a disturbance at your chest, and not knowing what to do with the whistles (p. 283). The Puerto Rican girl was very aware of her body and proud to s how it off and with the African American girl it was the total opposite perhaps because of the way she was treated and not allow to grow up without restriction place on her through racism and prejudice.One might wonder how will that affect her mindset as she get older, if I am mentally free in my mind to do what I want to do, my whole outlook on life will be different. The poem â€Å"What It’s Like to Be a Black Girl† Smith says,† the girl is getting bigger and taller and want to wear white clothing to supplement how she is feeling and while wearing white clothing everyone will accept her. The white clothing represent the good things in her life and black represent everything that is bad in her life.The African American girl, now a women and married at the end of the poem, her life appeared headed for trouble because of the upbringing she had. There seem to to be know one lift up the girl when she was going through the trouble time of her young life and all the o bstacles that was in her way. The disparity between the two girls is very obvious in the way they saw themselves. It was very sad that the African American girl did not have a good role model to tell her that black is beautiful and be happy with who you are. It would of been nice for her to have a big sister she could of looks up.The poem never really identified a support person she could count on even though we know there was someone there for her. Living in the 1950‘s was already rough for all minorities, especially before the Civil Rights Movement. The girl in â€Å"Child of the America’s†, seem to always have a great support net around her at times and you could see it in her attitude and the way she carried herself. The question I will continue to ask myself is who or what is responsible for the way minority girls viewed themselves? One girls seem to have a good support group around her and the other one did not.What cause the struggles of an African America n girl an a girl who is from the territorial of the USA so differently? The racism and prejudice minority had a major affect on how African American and Hispanic girls viewed themselves. The big question is who or what affected the girls the most in their growth from a young girl to a young woman. References: Clugston, R. W. (2010) Journey into Literature.
