4.i need help with a littiary anallisis essay Review of Violet Evergarden:1/13 episodes The story of ...

he story of Violet Evergarden, written by Kana Akatsuki, takes its viewers through a story of tragedy, hardship, and community of a recovering solder in thirteen episodes. The provided series shows the difficulties and challenges soldiers encounter when returning home after the Great War, much like World War I. One character, Violet, is a young female soldier who recently returned from war. In the past, she was utilized as a fighting machine raised for that purpose, and that purpose only. She had no emotions throughout her drafted time and did not understand people deeply. Following her service, she gained employment as an auto memory doll, much like a typographer. From this employment, she regained the use of her emotions through mentorships and friendships. This resulted in her becoming a highly requested person in her field. Violet was a child soldier in the Great War and was raised to fight and die for her cause. She was relieved of active duty following her hospitalization after her aquatint, Mr, Hodgin’s pulled some strings to have her discharged. Hodgin’s assisted Violet in finding a job due to his respect for his past friend and her mentor, Major Gilbert. She finally settles on becoming an auto memory doll, someone who writes for others. From her years of being a soldier, violet had become numb to her emotions. Because of the need for an auto memory doll to understand the client’s emotions, she thought this would be a good area of employment. While working as an auto memory doll for a foreign diplomat, she suffered a great loss of both of her prosthetic arms during an attack. While recovering, Violet learned of the prior death of her mentor Major Gilbert. At this time, she falls into a state of denial and has difficulty accepting this is with the support of a friend that she can accept his death and move forward in her life and become a highly recommended person in her field. After experiencing all of these tragedies, she can regain her emotions. Kana Akatsuki uses Violet to exhibit the worst-case scenario of the experiences of a soldier coming back from war. This is exemplified by her being a child soldier and the loss of her arms in action. These experiences resulted in her losing her emotions. Ms. Akatsuki’s portrayals of soldiers struggling with the aftermath of war are vividly explained. The mental problems and stress of losing one’s arms would cause one a great deal of distress, with having to relearn how to live one’s daily life. In episode one, Violet awakes in the hospital after a battle that costs her arms. I could only assume what uncertainty was coursing through her mind due to becoming reliant on others. How does one previously trained to be self-reliant now become dependent upon others? Even though she has been groomed out of emotions, she would undoubtedly feel despair. In episodes two through seven, Violet has a difficult time adjusting to civilian life. His work offers her the opportunity to grow through communication with others, resulting in new friendships. Upon learning of Major Gilbert’s death in episode eight, I feel that Violet expresses raw emotion for the first time in the series. Now understanding what loss is, Violet has a whole new outlook on life. She takes further job assignments, but she has a different tone in her writing as she expresses greater compassion towards others. During episodes eleven through thirteen, Violet gets thrown back into her life as a soldier. Because of her new understanding of emotions, she refuses to kill others to prevent inflicting that pain upon others. This was the first sign, in my opinion, that she was thinking about her actions and the effects they would have on other characters’ lives. For example, if she kills this character, his family will go through the same pain she did when she learned that Gilbert had died. This is a true sign of compassion. In episode 13, Violet attends an air show where she writes a letter to the Major explaining all she had learned. He wanted most for her to be a normal girl, and she expressed in the letter how she had done that. I feel like this is where she shows just how much she has grown personally and how she has adjusted to her new life. Ms. Akatsuki uses a great deal of symbolism to give the viewer a clear and decisive point of view into Violet’s life. At the beginning of the story, Ms. Akatsuki gave the viewers just enough information about Violet without spoiling the whole story. She slowly eases the viewers into the plot to allow just how difficult Violet’s life is, to truly sink into the mind of the audience. Throughout the show, the viewer becomes familiar with different characters, both young and old. I believe that Ms. Akatsuki took the time to match the voice actors with their characters. For example, the voice of Violet sounds like she is very unsure of herself while at the same time having a disciplined tone. Major Gilbert's voice actor has a kind and heartwarming tone. He sounds like someone who truly was invested in others’ well-being, someone who would take Violet in. The other characters follow these examples no matter how small their part is and that makes this story more engaging. The story of Violet Evergarden is one of hardship, tragedy, and a community. Portrayed by a true literary genius, Kana Akatsuki. This story takes its viewers through a roller coaster of emotions and draws them deeper into the story. Through the eyes of a Great War soldier. Violet, a child soldier, goes through a transformation from a once lacking emotional character, to an auto memory doll that writes for others. Where she conveys other emotions onto paper. It is through community, friendship, and healing that Violet follows a path to recovery. One that made her face many trials and allowed her to become a renowned person in her field.

8.Part I. Reaction Paper Read and understand the text below. Follow outline in writing your reaction paper at least 250-750 ...

paper at least 250-750 words. 1. Introduction 2. Thesis Statement 3. Supporting details 4. Conclusion The Digital Divide: The Challenge of Technology and Equity (1) Information technology is influence the way many of us live and work today. We use the internet to look and apply for jobs, shop, conduct research, make airline reservations, and explore areas of interest. We use Email and internet to communicate instantaneously with friends and business associates around the world. Computers are commonplace in homes and the workplace. (2) Although the number of internet users is growing exponentially each year, most of the worlds population does not have access to computers of the internet. Only 6 percent of the population in the developing countries are connected to telephones. Although more than 94 percent of U.S households have telephones, only 56 percent have personal computers at home and 50 percent have internet access. The lack of what most of us would consider a basic communication necessity the telephone does not occur just in developing nations. On some Native American reservations only 60 percent of the residents have a telephone. The move to wireless connectivity may eliminate the need for telephone lines, but it does not remove the barrier to equipment costs. (3) Who has internet access? The digital divide between the populations who have access to the internet and information technology tools and those who dont is based on income, race, education, household type, and geographic location, but the gap between groups is narrowing. Eighty-five percent of households with an income over $75,000 have internet access, compared with less than 20 percent of the households with income under $15,000. Over 80 percent of college graduates use the internet as compared with 40 percent of high school completers and 13 percent of high school dropouts. Seventy-two percent of household with two parents have internet access; 40 percent of female, single parent households do. Differences are also found among households and families from different racial and ethnic groups. Fifty-five percent of white households, 31 percent of black households, 32 percent of Latino households, 68 percent of Asian or Pacific Islander households, and 39 percent of American Indian, Eskimos, or Aleut households have access to the internet. The number of internet users who are children under nine years old and persons over fifty has more than triple since 1997. Households in inner cities are less likely to have computers and internet access than those in urban and rural areas, but the differences are no more than 6 percent. (4) Another problem that exacerbates these disparities is that African-American, Latinos, and Native Americans hold few of the jobs in information technology. Women about 20 percent of these jobs and receiving fewer than 30 percent of the Bachelors degrees in computer and information science. The result is that women and members of the most oppressed ethnic group are not eligible for the jobs with the highest salaries at graduation. Baccalaureate candidates with degree in computer science were offered the highest salaries of all new college graduates. (5) Do similar disparities exist in schools? Ninety-eight percent of schools in the country are wired with at least one internet connection. The number of classrooms with internet connection differs by the income level of students. Using the percentage of students who are eligible for free lunches at a school to determine income level, we see that the higher percentage of the schools with more affluent students have wired classrooms than those with high concentrations of low-income students. (6) Access to computers and the internet will be important in reducing disparities between groups. It will require higher equality across diverse groups whose members develop knowledge and skills in computer and information technologies. The field today is overrepresented by white males. If computers and the internet are to be used to promote equality, they have to become accessible to schools cannot currently afford the equipment which needs to be updated regularly every three years or so. However, access alone is not enough; Students will have to be interacting with the technology in authentic settings. As technology has become a tool for learning in almost all courses taken by students, it will be seen as a means to an end rather than an end in itself. If it is used in culturally relevant ways, all students can benefit from its power.
