Career Outlook for Information Technology *Works Cited Not Included Only once in a lifetime will a new invention come along to touch every aspect of our lives. A machine that has done all of this and more now exists in nearly every business in the US and one out of every two households. This incredible invention is of course the computer! How many people use computers either at home or at work? Computers have been around us for longer than most of us think. The electronic computer has been around for over a half-century, but its ancestors have been around 2000 years! However, only in the last 40 years has it changed the American society. The computer has changed nearly every aspect of people’s lives. The earliest existence of the modern computer’s ancestors is the abacus. It is simply a wooden rack holding parallel wires on which beads are strung. When these beads are moved along the wire according to â€Å"programming† rules that the user must memorize, all ordinary arithmetic operations can be performed. In the early 1800’s a mathematics professor named Charles Babbage invented the first punch card computer. Which read holes punched into cards. This technology advanced slowly. By the late 1930’s punch-card machines had become well established but were very slow. The outbreak of World War II produced a desperate need for computing capability, especially for the military. New weapons were produced which needed trajectory and other essential data. Associates at the University of Pennsylvania decided to build a high-speed electronic computer to do the job.

Civil War Journal Essay example -- essays research papers

1861, July 16 The battle of Bull Run ended today. Northerners, like myself, know it as Bull Run but the Confederates know it as Manassas. This battle is giving me bad thoughts about the outcome of this war. This was a Southern victory and the Confederate army looks high in spirit and high in confidence, compared to the hurt, tired, and disappointed North. The great leadership of the Confederate generals won this battle. Their plans and attacks were no match for the Union ones. I hope the North can do something to rebound from this great loss, maybe there will be a second battle. 1862, December 31 Today I attended a gathering at the Tremont Temple. It was in Boston so I had to travel a ways. At the Tremont Temple many black, including myself celebrated the issuance of the Emancipation proclamation that is effective at midnight tonight. At the gathering everyone's spirits were high and everybody was excited. The black men who have learned that the Emancipation could mean the end of slavery were as happy as little boys were when they were getting a present. They have forgotten everything bad about being black, but its only temporary, the struggling of slaves and in this time period cannot be measured. At midnight tonight, millions and millions of people's lives will be changed. 1863, January 1 Today, the 1st of January is the day where the Emancipation Proclamation issued by Abe Lincoln begins. The streets are filled with free blacks celebrating and rejoicing. People are having parties and celebrating but most of all praying. Groups of blacks are praying together and thanking God for setting them free. 1863, February 24 Today I became an agent for the U.S. Government to recruit Negro soldiers into the Union Army. These black men will be involved in all black regiments and fight the Confederate army. My prediction is that it won't be hard to find willing blacks to fight for the Union. I hope this is successful and the blacks will have a big part in freeing all slaves and winning the Civil War. 1863, February 27 Today I issued the "Men of Color, to Arms." This challenge to black men to fly to arms, and smite with death the power that would bury the government and your liberty in the same grave. I worked on the end of my message for a long time to get my point across, it sounded like this, "Remember that in a contest with oppression, t... ...can still survive without him. He has played a big part in rebuilding this country and if you are Southern or Northern you know that and recognize it. 1865, April Today I had another speech at the annual meeting of Massachusetts Anti-Slavery Society in Boston on "What the Black Man Wants." Basically it was about the rights blacks should have, and how we deserve them now because we are free. 1865, May 30 Another speech to add to my many†¦ I spoke at a memorial meeting on the life and death of Lincoln. Negroes of New York City called this memorial after New York Common Council refused to permit Negroes to participate in the funeral procession when Lincoln's body passed through the city. This was a great way to show how much we appreciate and respect Lincoln. 1865, August 17 Today I thanked Mrs. Lincoln for sending me the president's walking stick. This was a very nice gesture of her and I will cherish this piece of his life. 1865, October Today I delivered a lecture at the inauguration of Douglass Institute, school for Negro children. I think this school will help the black children learn and become successful in their life. I am glad I am making a difference.

Forecasting the Adoption of E-Books Essay

Question 1 The size of the market for e-books in the long-run: 293. 7 million x 46. 7% x 8% = 10. 973 million (Total US population x percentage of US population reading literature x Percentage of traditional paper books purchased online in 2003) It will take 10 years to reach 95% penetration of the potential market. Question 2 I predict that the sale of the e-book when it first became available is 0. 751milion (pm) (Assumption: each innovator buy one book. ) Question 3 The long-run total adoption of e-books would be 10. 973 million. (Total US population x percentage of US population reading literature x Percentage of traditional paper books purchased online in 2003) Question 4 I do expect the market for e-books tend to be guided by imitators rather than innovators. According to the table above, I found that the weighted average for e-book of q (0. 0684) is larger than p (0. 2990). In addition, the word of mouth takes an important role in the adoption of e-books. The information about the e-book from the innovators contribute much to the adoption of e-books since people tend to hesitate to change their old reading habit. Question 5 S(t)=[p+(q/m)N(t-1)][m-N(t-1)] Year 1: [0. 0684+(0. 2990/10. 973) X (0)][10. 973-0] = 0. 751 million Year 2: [0. 0684+(0. 2990/10. 973) X (0. 751)][10. 973-0. 751] = 0. 908 million Year 3: [0. 0684+(0. 2990/10. 973) X (1. 659)][10. 973-1. 659] = 1. 059 million Year 4: [0. 0684+(0. 2990/10. 973) X (2. 717)][10. 973-2. 717] = 1. 176 million Year 5: [0. 0684+(0. 2990/10. 973) X (3. 893)][10. 973-3. 893] = 1. 235 million Question 6 The adoption of e-book will be very different from digital music obtained online. The adoption of e-books face more challenges when comparing to the adoption of digital music. To most of the listeners, there is not much difference in experience between listening to a song from an iPod and a CD player. Therefore, they have a relatively low switching cost and more willing to change their habits. On the contrary, to most of the readers, it is definitely very different from reading an e-book to reading a printed book. The feelings of holding a printed book and flipping over a physical book are irreplaceable. So readers are loyal to printed book and hesitate to switch from traditional books to e-books. Hence, it is reasonable to predict that the pace of adopting digital music is faster than the pace of adopting e-books. Question 7 I think both of the attitudes about reading and purchasing e-content have changed a lot in recent years. In the old time, people could read e-content via PC only. Nowadays, people are able to read e-content through various mobile devices. Therefore, they spend more time on reading e-content especially during leisure time and even commuting time. However, the quality of the reading effort is diminishing as the overload of e-content available on Internet. In addition, people tend to rely more on the e-content since it is very convenient, environmentally friendly, high mobility and high accessibility. For the attitude about purchasing e-content, more people are willing to pay for the e-content in recent years. The advanced online payment system plays an important role. People feel more secure and also convenient when dealing online ever than before. Moreover, more well-known and large-scale publishers offer more choices of e-content for readers. Besides, in the light of the prevalent of mobile device, people have more time and chances to read the e-content regardless of the time and places. Thus, people are more willing to spend on e-content than before. Question 8 The hardware plays a paramount important role in the adoption of e-books. No matter how amazing the e-content is, the e-books would not be popularized if the hardware were not user-friendly. However, a good hardware is very likely to boost sales of the e-books. It is because the hardware is a fixed cost while the e-books are the variable cost to the readers. A portable hardware with proper size of monitor and high capacity is very attractive to the readers. They no longer need to neither carry the bulky printed books nor spare some places for storage. Moreover, the hardware enables readers to read comfortably when comparing to read via PC or smart phone. It is good for the readers’ eyes. Last but not least, the hardware contributed to protecting the environment as it saves much paper. Only when the hardware preforms better than the tradition printed books, the adoption of e-books will be success. Question 9 I do expect the size and also the pattern of diffusion are quite different globally as compared to the United States. The size and the pattern of diffusion depend on many factors. Population, culture, attitude to new products, technology and even literacy could be one of the variables of the size and pattern of diffusion. Take Africa as an example; though the population size of Africa is much larger than The United States, the potential size of the market for e-books must be obviously different from the United States. So it is not difficult to understand that the size and pattern of diffusion of various places will not be similar to the United States.

Effects of Poverty on Children

Name: Shem Blake Course: Child-Adolescent Development Lecturer: Mrs. Kennedy Date: February 19, 2013 Discuss how poverty affects the psychosocial, cognitive, moral and physical development of the adolescent The term poverty is usually used to simply refer to a lack of money, but living in a state of financial instability is both physically and emotionally damaging.While an adolescent who grows up in a middle class suburb is taught that he or she can go to college, marry, have a rewarding career, and make a meaningful contribution to the world at large, a child born into poverty must struggle to simply make it to adulthood. The long term effects of poverty are why this is a social issue that deserves public attention. Poverty is one of the most devastating preventable phenomena working against the healthy development of an adolescent whom are at a very crucial stage in their growth and development.During this developmental process they are going through, adolescents need an enhancing and stimulating environment to support their growth but if these adolescents are situated in poverty stricken environment their growth will be affected because through poverty they are deprived from needs and wants which is essential in their development and this alters their process of development as the effects of poverty may wrap, twist or arrest the process as the adolescents undergo psychosocial, cognitive, moral and physical development.Therefore, its far-reaching effect can be devastating to the development of adolescents. Poverty has a major negative impact on adolescent’s psychosocial development. According to studies by V. C. McLoyd, â€Å"persistent exposure to poverty has a directly negative effect on a child’s health†. The more obvious explanation for the reasoning of this are that lifestyle and living conditions for those who live in poverty affect a child negatively. Environmental deprivation is usually what we consider when we think about poverty , but it is not the only factor.Stressors such as unsafe or life-threatening living conditions and violence play a part. Among these is deprivation of other essential necessities that are needed, such as food, medicine and a safe home. Deprivation of any of these things, especially in infancy or early childhood has a marked effect on psychosocial development. As McLoyd points out, children who live in poverty are exposed to more extreme living situations than those who are not living under similar circumstances.These conditions may have a more pronounced effect or influence on them. During adolescent there is a large degree of psychological growth as children make adjustments in their personality due to the rapid development. They face ongoing conflict and difficulty adapting to the sudden upsurge of sexual and aggressive drive. These changes cause unrest and confusion in the adolescents’ inner selves and the way they perceive the world. During this maturation they establish their own beliefs, values and what they want to accomplish out of life.At this stage their also separating emotionally from parents while still being reliant on them but as they have to struggle with the challenges of poverty, instead of having a healthy psychosocial development they are at greater risk of behavioral and emotional problems  because they do not think of things the way they should instead they get a perverted mind especially against persons who are living in a better condition from them causing them to not think normally.Some behavioral problems may include impulsiveness, difficulty getting along with peers, aggression, attention-deficit/hyperactivity disorder (ADHD) and conduct disorder because they are in an environment which places a lot of limitations on them. Also, because of their poor status often times they are living in unsafe neighborhoods which exposes children to violence which can cause a number of psychosocial difficulties. Violence exposure can also p redict future violent behavior in youth which places them at greater risk of injury and mortality and entry into the juvenile justice system.There are different forms of poverty. When a child has been born into poverty, then poverty is seen as a fact of life which may or may not be something that can be changed. Hard work for survival is an expectation of life. The â€Å"rules† that apply differently to people who live in poverty are understood but adherence to the rules can be â€Å"conditional† when survival or basic needs are not being met. Hence, at this stage, where they are transitioning from concrete operational thinking to formal logical abstract) thinking including development in reasoning and judgment. So even though their thinking becomes multidimensional and they are better to contemplate situations their decision making remains susceptible to emotions due to their social environment restricts cognitive stimulation resulting in a lower motivation to learn b ecause the adolescents mind is always somewhere else, they have a short attention span because their mind is always thinking about food, and cognitive developmental delays because of poor nutrition.However, according to the American Academy of Child and Adolescent Psychiatry, the brain of a teenager continues to develop all the way into adulthood. The amygdala, the section of the brain that controls instincts, develops first. The frontal cortex, which is responsible for reasoning and determines how we act, develops later and continues to develop into adulthood. Because of this, a teenager is guided less by the frontal cortex and may not have a full understanding of moral behavior.So while the development of the cognitive skills is being delayed because of poor nutrition, the development of the moral skills are more severely delayed because they take a longer time to develop because the poverty stricken environment does not stimulates and enriches the development of this growth becau se their judgment are not mainly on what’s right or wrong but, what’s right or wrong for their survival. In their environment they are exposed to the temptations of drug, alcohol and sex from an early point in life but because this has been a norm in their upbringing they fall to the same temptations.Everyone knows that it is troubling having to deal with poverty, moreover, it is more troubling for adolescents because they are already going through challenges of their own adapting to a new mind and body, plus dealing with their life situations may bring them to a breaking point. Often times, their moral development is not based on what is right or wrong but the right or wrong ways of getting what they need or want, resulting in situations like gang violence, teenage prostitution and stealing causing deaths and even sexually transmitted diseases.Their moral development is affected because they still think in an abstract way and can be more impulsive than an adult. At th is stage their impulsiveness can prevent them from making decisions based on moral responsibility and they will believe no consequences will emerge from their actions. Not only does a poor nutrition and other social factors affects the adolescent in their psychsocial, moral and cognitive development but its most visible impact is on the physical development of the adolescent.Through this time they are going through a rapid change of the body but their development is slowed down because their body lacks the right nutrients that enhance their growth. They do not eat right and are ignorant to the concept of living a healthy lifestyle so in their development, if they are not underweight; they are overweight because their diet consists of a lot of carbohydrate, a small amount of protein and a deficit in other nutrients. Soobader and Leclere (2000) has also examined the impact of poverty on the physical health status of the adolescents.According to these authors, poverty can impact the ab ility of the family to receive and maintain health insurance. This specific issue can impact the overall health of the adolescence because health care is expensive and if the adolescent is fallen ill, if the ailment is not considered serious, then they will have to stay home and use home remedies only going to the doctor if it gets life threating and this is a very serious issue because the ailment could already be causing internal damage.In low-income families, acquiring proper medical care remains a pervasive issue that has clear ramifications for the health outcomes of the child. Although Soobader and Leclere do argue that the issues facing adolescence is quite complex overall, the inability to access proper healthcare and insurance has a notable impact on the outcomes for adolescence living in poverty. â€Å"The probability of a child being uninsured was associated with higher levels of income inequality at the county level and higher levels of poverty at the neighborhood level .Therefore, the deteriorating physical environment and the lack of social services compounds individual disadvantage† (p. 230). When poverty is a lifelong proposition for adolescents, it does not mean that an adolescence will develop into a lesser form of a human being when they reach adulthood. In fact, honor, values, beliefs, community structure can produce well form individuals under conditions most of us would consider horrific. But the lack of food, medical care, and other horrific social conditions may cause lifelong psychosocial, cognitive, moral and physical impairments for the adolescents.Without a solid community or family structure, the overall lack of basic subsistence will cause preventable and inexcusable deaths that can give an adolescent a warped view of the value of life.

First Day on Earth Pro and Antagonist Essay

In the novel â€Å"First Day on Earth†, the protagonist is a boy named Mal whom believes he is an alien and is being tracked. He thinks he doesn’t belong on Earth and is needed in outerspace. Mal’s Father left his mother when he was a kid and now lives with his mother whom is often drunk. He often goes to an abductee support group where he meets people with other worldly secrets of their own which they share at this group. Also,Mal meets a guy named Hooper who seems to be somewhat like Mal. Hooper says he is an alien and Mal thinks that some day these aliens will find him and he is going to be free. Mal is very different from everyone else. He is bullied by all the popular kids and is often ignored. He never likes to share his thoughts in class about anything because he thinks they are stupid and everyone will laugh at him. Mal is the kid with greasy hair, slumped in the last row of seats in class. The kid whom everyone is afraid to talk to. He is full of secreats. Years ago, he disappeared in for three days. weather it was a breakdown or an alien abduction, even Mal isn’t sure. In my opinion, the song â€Å"Fireworks† by Katy Perry describes the character of Mal very well. This is because the quote â€Å"baby your a firework, come and let your colours burst† means that don’t be afraid of what others think of you, just do what you think is right. In this novel, Mal’s character is exactly like this verse from the song because he believes he is an alien and doesn’t care what others think of him. he keeps stuff to himself and doesn’t mind anyone else’s business or what they think about him. Mal is a very loving and caring kind of person. He has only two friends, Mark and Sameer whom don’t sit with him at lunch because Mal likes the outdoors and they dont. All the popular kids ignore him except for a girl named Posey. She doesn’t care what anyone thinks about her,she’s just always nice to Mal and is always willing to help out. Mal likes animals and can’t see them in trouble, so whenever he finds lost or hurt animals, he brings them to a shelter where Posey’s mother works. That way, the animals are taken care of very well, and Mal gets a chance to get closer to people. When Mal goes with Hooper to send him back home, Mal tells him he wants to go with him and how he doesn’t like it being on Earth. Hooper tells him that he is his only friend and doesn’t want any harm for him, so he refuses. When Hooper leaves into the distance, Mal, Posey and Darwyn go back into the car and go on their way back home, when Mal decides to make a U-Turn and goes back into the place where he left Hooper. Mal decides to go and follow where hooper had left and ended up in space. He then made a really tough decision of staying in Earth because of the people whom need him such as his drunk mother, friends and most importantly, Earth. Antagonist In this novel, the antagonist is a boy named Hooper. Mal meets him at an abductee support group where people share their stories of what they think happened to them. As Hooper shares his story, Mal gets really interested and gets confidence to share his own. As everyone heard Mal’s story, they reacted like nothing happened so Hooper gave him a thumbs-up to show him it went fine.Almost everyone in the group was older than Mal except for Hooper. He was the only person at the abductee support group who was almost the same age as Mal/looked like it. As Mal and Hooper get to know each other a bit more, Hooper tells Mal that he is an alien and doesn’t belong at Earth,which is exactly what Mal thinks about himself. As Mal was driving, he saw a dog and decided to follow it so he can give it to the shelter. The dog ran and went to Hooper whom was living in a box. Mal was shocked and wanted to talk to him about it so he took him to a Burrito place and said it was his treat because he wasn’t sure if he had any money. He told him to take his belongings with him so he can take him to a shelter home. In my opinion, the song â€Å"E.T† by Katy Perry describes the character of Hooper very well. This is because it describes how Hooper is an alien and is different/ has different ways to do things. The verse â€Å"They say, be afraid,your not like the others†¦Ã¢â‚¬  means that people say to be afraid but your not like others so there is no need to be afraid. I believe this is Hooper’s character because he isn’t afraid of humans even though he is an alien and doesn’t know much about humans. Hooper is a very straingt forward kind of person. He says everything direct of whatever he thinks. Outside of the support group, he regularly meets Mal except after he went to the shelter home. After the day Mal took him for the treat to Burrito’s, Hooper’s favourite food became Burrito’s. He would go there almost everyda. One day when Mal and Hooper met, Hooper treated Mal to eat Burrito’s. Mal talked to hooper of how he believes he is an alien and wanted him to take him to outerspace. Hooper starts to laugh and says he is his only friend, and doesn’t want anything to happen to him, and refuses. When Hooper and Mal get very close to eachother, Hooper shows Mal the star chart and tells him how he is an extraterrestril. He also lets Mal keep the chart, but Mal refuses because he thinks he will loose it , so Hooper decides to give him a copy of the chart instead. Near the ending of the novel, Hooper tells Mal that he needs to go to his actual home because it is now or never.

Penn State Scandal Essay Example | Topics and Well Written Essays - 750 words

Penn State Scandal - Essay Example On the hand of the social bond theory, the strong point is on the lack of social attachments amongst the juvenile delinquents. Effect on lives is as a derivative of friends, family and other members of social network (Rankin). The application of these theories supports the Penn State sex scandal. Penn state University being one of the best universities least expected such crisis. The society expects the athletics officials and coaching staff to be role models of youngsters. The university and the family of Sandusky had a blind eye in his association with wrong peers (Jenkins). In 1999 after the resignation of Sandusky, the Penn state football authorities still gave him access to campus premises and facilities. This gives him an open opportunity and advantage to make sexual advances to the boys. Gary openly assumes the Sandusky’s investigation. Instead of coordinating the solution to the scandal, he is a cause and only the bans Sandusky from bringing children to the campus. Gra ham Spanier, the president of the university neglects the report of crisis at an early stage that later deteriorates the Universities legacy (Frank). Reaction of the students has a basis as internal control in support of social bonding theory. Firing of Paterno had a controversial information upload. This was a weak unethical decision by the Penn board of state. The explanation was that the famous football coach did not act as a leader. His hesitation to report to the pre-informed case to police is a support of a crime. Paterno had the responsibility to his career goal as a coach and neglected organizational activities. Reputational recovery from the states university riots tarnished its image to a long-term crisis. There is also some information that Penn State issues is of a mafia family interest (Becker). This gives birth to reason as to why Paterno had no impact to make rather choose to be quiet. The two main characters behind the scandal are from the same school of thought and provide the solution to their problems in their own way. Some part of this case delay may be to avoid negative opinion on the University. This serves the same purpose as image restoring theory. This can cause pain and disappointment and fracture the relationship between the official and other involved parties. This serves as an indirect control of the case theory. Back in 2002, McQueary happened to report seeing Sandusky raping a very young boy in the showers of campus. He also informed Joe Paterno. Upon informing the director of athletics, Tim Curley and Gary Schultz who is the university police overseer, but the report did not appear before the prosecutor (Becker). The mother of the affected boy reported the case to the university police in 1988, but no step is into consideration. The university should have enacted sharing of information to students, stakeholders and proper audience to diffuse the crisis. This supports the tendency of criminal participation because Sandusky had no thing to lose from deferral antisocial behavior (Frank). Through the satisfaction of the involved parties needs, there was reluctance in the scandal investigation. Several influential people have supported the cover up of this scandal. The governor of the state who is the board of trustee assumed informing the authority (Jenkins). Even after clear evidence from the detectives who had eavesdrop of some conversation between Sandusky and the mother of the molested boy attorney Ray pressed no charges. Because of political and
