It was invented by two scientists namely J. P. Eckert and J. W. Mauchy. It was very huge and big. Its weight was 30 tones. It could store only limited or small amount of data. The second generation computers were invented from 1955 to 1960. The first transistor computer was created at the University of Manchester in 1953 and the most popular of transistor computers was IBM 1401. Its transistors were used as the electronic component instead of vacuum tubes. The size of computer was decreased and it became much smaller than that of earlier computer. Next, the third generation computers were invented in the 1960s. They were invented in 1964. IC was used as the electronic component of computers. Those computers were developed by T. S. Kilby .

The Importance of Mrs. Hale and Mrs. Peters in Susan Glaspells Trifles

The patented murder mystery, in all its addictive predictability, presents the audience with numerous cliches: a stormy night, a shadowy figure, a sinister butler, and a mysterious phone call. Susan Glaspell's Trifles does not fit this mold. Glaspell's mysterious inquiry into the murder of John Wright presents the reader with only one suspect, Mrs. Wright. Even though the court examiner and sheriff cannot find evidence against Mrs. Wright, the reader can plausibly argue the case against the neglected wife. Glaspell's use of descriptive language and subtle hints established the mood, presents the motive, and uncovers the evidence needed to solve this murder mystery. Setting the proper mood is important for any play, especially one that requires that its readers be wary of the surroundings. The first glimpse the reader gets of the setting is that of an "abandoned farmhouse . . . [and] a gloomy kitchen" (Glaspell 127). These first words give the readers a heightened state of tension and prepare them for darker events yet to come. Mrs. Hale repeatedly describes the cold house as not being "a very cheerful place" and mentions that it might not have been "any cheerfuller for John Wright's being in it" (130). These comments coming from a neighbor lead the reader to believe that Mrs. Wright was not happy in her surroundings largely because of her husband. Even the rocking chair in which Mrs. Wright sat seems tainted with unpleasantness. Mrs. Peters ahs to "shake off the mood which the empty rocking chair [evokes]" (131) before she continues her conversation with Mrs. Hale. The strange feeling the house provokes prods the women to think more deeply into the events leading to John Wright's death. This curiosity allows the women to u... ...would have much more difficulty portraying the evidence to the reader. This portrayal not only makes the story more interesting, but it also increases the character development of this short drama. Works Cited Banner, Lois. Women in Modern America: A Brief History.

Effects on Children in Single Parent Household Essay

The U.S. Census Bureau reported that about 30 percent of American families are headed by only one parent. Single parent households numbered over 12 million in the year of 2000. According to this, single parent families can no longer be viewed as nontraditional families. These families are all around us today. So, interest has grown as to the effect of these households on Children’s well-being. The most important effect of single parent household on children is in academic achievement. According to the research named Single parenting and children’s academic achievement from Kunz (2010), most single parent households are run by mothers. Therefore, children who lack fathers’ attention can’t have a happy learning environment. They usually perform poorly in school because the lack of guidance on their homework. From this research, we can conclude that for every 100 dollars of child support mothers receive, their children’s standardized test scores increa se by 1/8 to 7/10 of a point. In addition, children with single mothers who have contact and emotional support from their fathers tend to do better in school than children who have no contact with their fathers. We can make a conclusion from this research that because children live in single parent household, they can hardly do well in academic achievement. Emotional effects also play an important role in the life of children growing up in a single parent household. According to the article named Children in single parent homes and emotional problems by Erica Williams (2003), living in single parent household can have many emotional effects on children, including feelings of abandonment, sadness, loneliness and difficulty socializing and connecting with others. Nowadays, because living in single parent household, more and more children become autistic. They can’t develop interpersonal relationship with normal people, which avoid them from surviving in the society independently. Besides, since they are given little attention, there are also other emotional effects on them, including low self-esteem, increased anger, frustration and an increased risk for violent behavior. Further, they are more likely to commit a crime because they want to attract people’s attention. This can not only ruin their lives but also break their parents’ hearts. Although there are so many negative effects on children in single parent households, it can have positive effects on them as well. According to a study at Cornell  University, positive single parenting did not show any negative impact on the social and educational development of the 12 and 13 years old participating in the study. In addition, children in single parent families may exhibit strong responsibility skills, as they are often called upon to help out more with family chores and tasks. Therefore, if children in single parent households are taught and educated by the single parent in an appropriate way, they can become people who are more strong and independent than the normal children in normal families. Because they lack love, they learn how to survive in this complex society and live a happy life and become stronger and stronger. To help the children in single parent households, our whole society is supposed to pay more attention on them. If we can give more care and patience to them, they will become strong but not evil. They are the most innocent part of their families, and they are supposed to be treated as the normal children in normal families. Please give your love and care to them. References Kunz, M. (2010).

Quite the opposite, policy implementation has grown through the 1990s and into the twenty-first century. Surprisingly, a sizeable number of publications are located outside the core field (Saetren, 2005). Therefore, the core field consisted of approximately 60 different journals that published over 454 implementation articles over a 60-year time frame. The area of concentration from these statistics of public policy implementation was: public policy, public administration, and political science.
