Jamestown and Plymouth Plantat essays

Jamestown and Plymouth Plantat essays The beginning of colonization was very difficult for the early settlers in the New World. Disease, starvation, greed, and aggressive Native Americans were factors that lead to the end of many colonization attempts in the Americas. The first two successes were Jamestown and Plymouth Plantation. There were many differences between the two, such as the type of local government established, the kind of relationships maintained with the local natives and the way they became self-sufficient. Jamestown used military rule for much of the first decade as a colony. They soon moved to an assembly that was elected by the people. Before the inhabitants of Plymouth Plantation set foot on the New World in the leaders of the expedition drew up the Mayflower Compact, by doing so they formed a civil government. This gave them claim to the land and to rule it in the name of the King. These early forms of democracy seem to have been the best way to rule, due to the many ideas and different backgrounds of many of the inhabitants. Jamestown was on shaky ground from the beginning with the natives leading to two wars with the Pawhatan Indians. They alienated any Indian allies they might have had by forcing them to bow before the King of England. Plymouth started off on the right foot by procuring the help of two English-speaking Indians. These two Natives taught colonists how cultivate corn and acted as envoys with the local natives. This allowed for extensive trade with the Indians of that region. The Plymouth colonist had surpluses of corn crop, which they traded with northern natives for furs. They soon made agreements with the Dutch to split the fur and wampum trade in the New England area. Jamestown on the other hand cultivated many varieties of tobacco and exported it to Europe. Tobacco was in such high demand that the Virginia Company of London pumped more people and money in to the co ...

How to Prepare Aqua Regia Acid Solution

How to Prepare Aqua Regia Acid Solution Aqua regia is an extremely corrosive mixture of nitric and hydrochloric acid, used as an etchant, for some analytical chemistry procedures, and to refine gold. Aqua regia dissolves gold, platinum, and palladium, but not the other noble metals. Heres what you need to know to prepare aqua regia and use it safely.​​ Fast Facts: Aqua Regia Aqua regia is a corrosive acid mixture made by combining nitric acid and hydrochloric acid.The usual ratio of acids is 3 parts hydrochloric acid to 1 part nitric acid.When mixing the acids, it is important to add the nitric acid to the hydrochloric acid and not the other way around.Aqua regia is used to dissolve gold, platinum, and palladium.The acid mixture is unstable, so it is usually prepared in small amounts and used immediately. Reaction to Make Aqua Regia Here is what happens when nitric acid and hydrochloric acid are mixed: HNO3  (aq) 3HCl (aq) → NOCl (g) 2H2O (l) Cl2  (g) Over time, nitrosyl chloride (NOCl) will decompose into chlorine gas and nitric oxide (NO). Nitric acid auto-oxidizes into nitrogen dioxide (NO2): 2NOCl (g) → 2NO (g) Cl2  (g) 2NO (g) O2  (g) → 2NO2(g) Nitric acid (HNO3), hydrochloric acid (HCl), and aqua regia are strong acids. Chlorine (Cl2), nitric oxide (NO), and nitrogen dioxide (NO2) are toxic. Aqua Regia Safety Aqua regia preparation involves mixing strong acids. The reaction produces heat and evolves poisonous vapors, so its important to follow safety protocols when making and using this solution: Make and use aqua regia solution inside a fume hood, with the sash down as much as is practical to contain the vapors and protect against injury in case of splashing or glassware breakage.Prepare the minimum volume needed for your application.Make sure your glassware is clean. In particular, you dont want any organic contaminants because they can produce a vigorous or violent reaction. Avoid using any glassware that may be contaminated with a chemical containing a C-H bond. Do not use the finished solution on any material containing an organic.Wear safety goggles.Wear a lab coat.Wear gloves.If you get drops of any of the strong acids on your skin, wipe them off immediately and rinse with lots of water. If you spill acid on clothing, remove it immediately. In the  case of inhalation, move immediately to fresh air. Use the eyewash and seek emergency medical attention in case of eye contact. In the  case of ingestion, rinse the mouth with water and do not induce vomiting.Neutralize any spills with sodium bicarbonate or similar compound. Remember, its best to neutralize a  strong acid with a weak base and not a strong base. Prepare Aqua Regia Solution The usual molar ratio between concentrated  hydrochloric acid and concentrated  nitric acid is HCl:HNO3 of 3:1. Keep in mind, concentrated HCl is about 35%, while concentrated HNO3 is about 65%, so the volume ratio is usually 4 parts concentrated hydrochloric acid to 1 part concentrated nitric acid. A typical total final volume for most applications is only 10 milliliters. Its unusual to mix up a large volume of aqua regia.Add the nitric acid to the hydrochloric acid. Do not add hydrochloric to nitric!  The resulting solution with be a fuming red or yellow liquid. It will smell strongly of chlorine (although your fume hood should protect you from this).Dispose of leftover aqua regia by pouring it over a large amount of ice. This mixture may be neutralized with a saturated sodium bicarbonate solution or 10% sodium hydroxide. The neutralized solution may then be safely poured down the drain. The exception is used solution that contains heavy metals. A heavy metal-contaminated sol ution needs to be disposed of according to your local regulations. Once you have prepared aqua regia, it should be used when its fresh. Keep the solution in a cool location. Do not store the solution for an extended length of time because it becomes unstable. Never store stoppered aqua regia because pressure build-up could break the container. Another potent acid solution is called chemical piranha. If aqua regia isnt suitable for your needs, piranha solution may be what you need.

Poetry Richard Cory Essay Example | Topics and Well Written Essays - 750 words

Poetry Richard Cory - Essay Example ... rhyme scheme is suggestive of the meaning behind the poem-that you cannot know what somebody is like inside just from the outer appearances. The rhythm of the stanzas, as well as the light tone that the poem starts in, are not at all foretelling of what is to come in the last stanza, unless if one employs irony and listens to the foreboding that this poem seems too light to be taken at face value. Thus the rhythm of the poem-regular, perfect grammatical stanzas, and the rhyme scheme which follows in an orderly way, seem to show the outside perfection of Richard Cory's life. However, only the last two stanzas give away (what goes on in) his inner life, and this is in sharp contrast to the outside appearances, in fact, completely contrary to the seeming perfection. The second stanza describes Richard Cory's behavior in a social sense, and more of his effect upon other people. The third stanza describes his social standing and his position, and we see him as a very wealthy man. But he is also "schooled in every grace", which makes him somewhat of a hero figure, as he is not only rich and handsome, but also of a fine mind and fine manners. Thus up to the end of the third stanza, what we as readers are offered is this description of Richard Cory, in which we see him as a bright character, and almost like a model citizen in a way. ... This is also a general opinion of other townspeople of him. So up to this point the poem's beauty seems to be in perfectly lined up, almost symmetrical sentences, told in a style that is almost classical in its simplicity and elegance. The focus is on detail in the description of this character. Thus we see elegant expressions such as "imperially slim", "quietly arrayed", and further-"he was always human when he talked". Finally, at the end of third stanza, Robinson concludes the detailed true-to-life description by saying: "In fine, we thought that he was everything/ To make us wish that we were in his place". Note that he says: "[W]e thought", and not another verb of more certainty such as "we knew" for example. It is still not obvious to the reader that a tragedy will follow, but the choice of verb here underlines the fact that appearances do not have to be true to what is going inside of a person. The last stanza suddenly gives us more insight into the socio-economic position of the narrator, as well as the other townspeople: "So on we worked, and waited for the light,/ And went without the meat, and cursed the bread". Thus it is now established that the narrator, as well as most of the townspeople, are poor, in contrast to the wealthy and successful Richard Cory. Finally, the poem ends: " And Richard Cory, one quiet summer night,/ Went home and put a bullet through his head." Note the perfectly grammatical, symmetrical sentences in this stanza, and the orderly rhyme scheme-ghgh. The perfect symmetry of this poem is ironic in contrast to the internal chaos that is shown through Richard Cory's sudden suicide. However, there is not much emotion shown from the narrator with regards to Richard Cory's

Fatherhood Essay Example | Topics and Well Written Essays - 2500 words

Fatherhood - Essay Example .. The methodology for this study is to examine 'what makes a man a father' with reference to psychological, critical psychological and sociological perspectives. The literature search for psychological information regarding fathers, parenting and other topics that related to 'the nature of the claiming process for fathers' revealed a number of journal articles, books and articles in popular magazines like Psychology Today. Beaton, Doherty and Rueter (2003) conducted a detailed study designed to examine "family of origin processes and attitudes of expectant fathers" Methodology for the study included structural equation modeling and multiple regression analysis with a sample of 152 couples. The 'eco systemic model of fathering was tested and used to examine the 'relative strength of the modeling hypothesis and the compensation hypothesis for linking these constructs." The authors discovered that expectant fathers "who were either very close to their parents of very distant from their parents during childhood had more positive attitudes about father involvement." The authors of this study also note that "expectant fathers who believed their own fathers were competent in their paternal roles, had stronger attitudes about fatherhood. ... .." The eco-systemic model of how family of origin history and processes are associated with attitudes about father involvement previous to the birth of a man's first child were thoroughly examined in the new study along with reference to previous research of a similar nature. The authors point out that despite the fact scholars have been hypothesizing for decades that "family of origin processes are associated with future father involvement (work by Doherty, Kouneski and Erickson, 12998; Pleck, Charonoy and Levine, l985 and Pleck 1995 was cited in the article) little research has actually been done to test the hypothesis until they began to look at this particular issue. Beaton points out that "According to Doherty et al.'s (1998) eco-systemic model of father involvement, five interrelated factors determine responsible fathering: co-parenting relationship, mother factors, father factors, contextual factors and child factors. These factors interact with one another to determine how fathers will be involved with their children. These factors interact with one another to determine how fathers will be involved with their childrenIntergenerational processes from the past interact with current relational factors to determine father involvement" The new study by Beaton and colleagues (2003) was an investigation of "how these processes work" In keeping with traditional psychological models this study included an extensive literature review that clearly illustrates the serious and extensive efforts that have been undertaken in efforts to create a better understanding of the eco-system model in relation to our topic. "There have been two prominent conceptual models for understanding intergenerational influences on current family relationships: intergenerational

Ventilation Activities Assignment Example | Topics and Well Written Essays - 500 words

Ventilation Activities - Assignment Example When making a ventilation hole, the smallest size for a commercial building should be 4X4 feet. If the roof is panelized, the crew should not make the hole right over the fire; instead, it should be made as close to the fire as safety permits. In the case of a single family residence, the hole needs to be 2X4 feet. Crews need to make sure they stay focused on the fire burning, as well as the pressure they are venting. They also need to make sure that the ventilation hole is large enough. The wind should remain at the backs of the crew so the smoke will not be directly inhaled. When they have completed making the ventilation hole, they should then report back to the Incident Commander (Structural Fire Attack). Anytime personnel go to the roof, they are to assure two "IDENTIFIED ESCAPE ROUTES" are in place. In some cases, the building may have a built-in ladder that can be used as a secondary escape route, or the crews may be able to exit to another building that has a separate roof. Crews operating on a roof are to have a minimum of 1 sounding device, 1 pike pole, 1 chainsaw, and a portable radio. When cutting a ventilation hole, crews should be aware of fire burning at the edge of the hole or smoke venting under pressure. If this occurs, the ventilation hole has not been cut large enough.

Teenage Pregnancy: Health and Social Issue Analysis

Teenage Pregnancy: Health and Social Issue Analysis Today teenage pregnancy is evolving as a serious problem all over the world. It defines as getting pregnant below eighteen years. Researches reveal that almost fifteen million teen pregnancies occur every year. These teen pregnancies are mostly common in developing countries where teenagers lack parental monitoring and they are unaware of modern birth control methods. Many teenagers plan to get pregnant, but mostly do not. Unplanned pregnancies occur at all levels of age, creed, and race with a particular negative impact among teenage population. Teen pregnancy is an important social problem and as well as a major health issue, that need to reduce because of the negative consequences that it bears on teenagers. They are at risk of conception and many sexually transmitted infections. On fearing the medical procedures and parental responses, they hide the fact of pregnancy and therefore are at more risk of its severe consequences. They did not receive parental care on time. Moreover, studies shows that teenagers are psychologically immature and unstable and the additional stress of pregnancy on them brings up negative results. In 2000, â€Å"The Health of Nation† failed to reduce the rate of teen pregnancies. Another policy set the target to halve the rate by 2010. In order to achieve the target, many other policies were set based on researches especially on focusing the importance of parental monitoring and use of contraception. Recent literature on teen pregnancy prevention mostly focuses on parental monitoring. Role of parents in this issue is crucial. They are responsible for educating their children and providing them enough knowledge about the negative consequences of teen pregnancies. The rate of teen pregnancies is high especially among those who suffer from poor education in their childhood. Another interest that lies on the parent’s role in reducing the unplanned teen pregnancies is by talking openly with the teens about this issue through several controversies exist on whether it increases the sexual activity or vice versa (DiClemente, 2001). The studies mainly focus on parental monitoring in order to prevent teen pregnancies because the effectiveness of the parental influence in attitude, knowledge, and behavior among their children lower the teen’s risk of adolescent pregnancy. Research shows that higher parental monitoring decreases the sexual activity and avoids unplanned pregnancies in teens. Parental monitoring has a positive effect on healthy adolescent development. Influence of parental role and relation between parenthood and teen pregnancy is clear in this issue. In order to have an effect or successful outcome of parental monitoring, not only teenagers but parents also need education to monitor effectively without being overprotective. They need education to talk efficiently to their children about birth control methods, safe sex, and sexually transmitted diseases. The parents need to focus on their views and concepts about sex education and find out if they are comfortable and know how to talk to their children. Identification of adolescent females who are usually at high risk of getting unplanned pregnancies is the key to prevention. Parents require education no matter the setting of teen is at the primary care office, clinic, school, or emergency rooms. Further research needs to be done for improving parental skills and their outcomes. Nationally, the teen pregnancies are increasing at a staggering rate. However, some appropriate programs help in preventing these pregnancies among the teenagers. There are federal laws for promoting abstinence only education and providing funding for these programs based on abstinence. Such programs not only help to prevent the teen pregnancies but they positively correlate with decrease in the amount of unplanned pregnancies and births among teenagers. The recent literature study of Stanger-Hall and Hall in 2011 reveals that the most effective approach is the ‘level 1 style’ that provides comprehensive safe sex education and STD education. It covers the use of birth control methods and abstinence. The Nurse Practitioners (NPs) are confident in educating parents about the positive impacts of these programs in preventing teen pregnancies (Stanger-Hall, 2011). Several intervention based programs need to help prevent the unplanned pregnancies in the adolescent. Some of the interventions require coming from the parents at home or office of primary care provider. It is the job of NPs to identify those adolescents, who show high-risk behavior in these pregnancies. The NPs need to ensure the confidentiality of their patients and develop the trusting relationship with them. They need to give education to the parents efficiently and refer them to the websites or groups regarding teen pregnancy prevention. Contraception or the use of contraceptive methods is another way of preventing teen pregnancies. Research shows that most of the unplanned pregnancies among the teenagers are due the fact that they are either unaware of using contraceptive methods or they do not use contraception consistently. Free contraceptives available and provided for high and middle school students within schools around the world help in preventing the great amount of teen pregnancies. However, these schools preferred to give contraceptives to only those children who have their parents’ permission (Shoupe, 2007). A comprehensive education on safe sex has successful effects on the use of contraception. The Family Growth National Survey reveals that teenagers who receive safe sex education that includes contraception and prevention from sexually transmitted diseases, are less likely to have unplanned pregnancies. Contraception such as birth controls and condoms offered at affordable or discounted prices may help to reduce teen pregnancies. The effective and appropriate use of contraception will contract sexually transmitted diseases. It will not encourage the teenagers to have sex but will lower the risk of unplanned teen pregnancies. School-based health centers or SBHCs is a great community resource for adolescents to provide friendly primary care services to this population. More SBHCs need across the nation to open in order to release their restrictions of providing contraceptive services. Intervention based programs are changing the sexual education standards which means to change some of the laws at the federal, state, and local level. The new standards of National Sexuality Education released in 2001 focus on changing the federal, state, and local laws. Social programs started with the purpose of preventing teen pregnancies began to disappear slowly. US administration provides some limited financial investment only for evidence based programs. Adolescent Pregnancy Prevention Programs and other programs like Planned Parenthood help to prevent the teen pregnancies by providing low cost or free birth control and contraception to teenagers (Bennett, 2005). In this way, service providers implement these programs effectively and successfully. They are developing new strategies and polices that will prevent unplanned teen pregnancies. In conclusion, teen pregnancy is preventable that is a major social and health issue burdening many communities around the world. Early comprehensive and effective safe sex education including parental monitoring and contraceptive prevention is the important key that needs to start by the parents at home and reinforced continually at school and primary care office.

Standardized Testing in Schools: The Analysis Essay -- Standardized Tes

Standardized Testing in Schools: The Analysis Abstract Within this paper we hope to answer lingering questions about the effectiveness of standardized testing in schools. Throughout our research we found many instances and sources of information to help us reach our goal. Standardized Testing had grown to play an enormous role in controversy concerning the Education system within the past decade. Hopefully throughout our paper it can be understood as to why this occurred and what can be done about it. Group Paper: Standardized Testing in Schools Standardized tests are used all over the country as a means to measure students’ academic performance. Often the students become frustrated upon taking these tests and in turn do not perform at their optimal level. Research has shown that standardized tests cannot fully represent a student’s intelligence or achievement. For the longest time, the education system has used a school’s test scores as competition between itself and other schools. This is because administering a test is less expensive than changing a curriculum. Reformatting instructional time, reducing class size, or accommodating new teachers would most likely be more of a waste of money than simply placing a test on a desk. The better a school’s test scores are, the more likely it is to be highly ranked across the country. Schools strive hard to have their students’ scores increase, not decrease. Looking back on tests of previous years, teachers can examine where students excelled and where they did not perform as well. Using this, they can adopt a new and improved test for students, which will make performance in certain areas, seem to increase (Patten, 2000). Teachers tend to teach and administer u... ...ved October 17, 2003 from http://www.msp.msde.state.md.us/rschool.asp?crypt=%A8%82rx%83%8CJ%A6%8A%A7%8F%9Fjc%A6%A1nh%A6%94%8C%93%9E%AF%B6%BA%B3%C8%AE%A1pp%A7%A7%AA%C7%D0Nx%86%A0%AE%89%84%A8%B4%A5%B0%A1%8E%9C%98q%94%9C%97n%A4%9Fh%ACs%5E%83%A4%95j%8C%A1%83%7F%93o%9Cw%96%8F%A6%98%AD%92%CA%B2 .
