How To Use the Common Spanish Verb ‘Tener’

The everyday Spanish verb tener, usually translated as to have, is particularly useful. Not only is it used to indicate possession, it is also used in a variety of idiomatic expressions to indicate emotions or states of being. Note that when tener means to have, it does so in the sense of meaning to possess or to own. The equivalent of the English auxiliary verb to have, as in you have seen, is haber (as in has visto, you have seen). Using Tener To Mean ‘To Have Most of the time, tener is used in much the same way as to have is in English. Depending on the context, it can also be translated using using synonyms such as to possess and to own: Tengo tres hijos. (I have three children.)Tiene un coche casi nuevo con una garantà ­a fuerte. (He owns an almost new car with a strong guarantee.)Antes de la guerra, tenà ­a tres casas. (Before the war, she possessed three houses.)Tuvimos cuatro campeones en el mismo momento. (We had four champions at the same time.)En 2016 Paulina no tenà ­a carnà © de conducir. (In 2016 Paulina didnt have a drivers license.)No tenemos suficientes bosques en el planeta. (We dont have enough forests on our planet.) ¿Crees que tendremos una mujer presidente? (Do you believe we will have a female president?) Tener can similar be used similarly as to have even when it is used figuratively or referring to nonphysical things: Espero que tengas una buena excusa. (I hope you have a good excuse.)Mi amigo tiene dificultad para pronunciar las palabras espaà ±olas. (My friend has difficulty in pronouncing Spanish words.)Cada là ­der debe tener una visià ³n de lo que podrà ­a ser. (Every leader should have a vision of what could be.) Idiomatic Uses of Tener Expressions using tener are also quite common. Many of them would not be understood by English speakers to indicate possession, although they often can be thought of as referring to to the having of various emotions and feelings. For example, tener hambre, would be translated literally as to have hunger, although it would normally be understood as to be hungry. The following listing, which is far from complete, shows some of the common expressions or idioms using tener: tener ____ aà ±os (to be ____ years old): (Tiene 4 aà ±os. She is 4 years old.)no tener antecedentes (to be unprecedented): La crisis venezolana no tiene antecedentes.

Public Breastfeeding And Its Effect On Children - 1975 Words

Public Breastfeeding If you went to a restaurant and saw a mother feeding her child formula from a bottle would you even think twice about it? Most people probably wouldn’t notice. What if it was a mother breastfeeding her child? Many individuals are offended by public breastfeeding and don’t see it as just a women doing her motherly duty and feeding her child, as with bottle feeding. Public breastfeeding has become quite the topic of controversy lately in America. Breastfeeding is simply the feeding of infants with milk from their mother s breasts, and those who choose to do this in public are often the victims of harassment from individuals within their communities. Public breastfeeding, in America, is a mother’s right and to improve the health and well-being of children, it must be accepted. Benefits for Babies Breast milk is best for infants. It reduces the risk for SIDS, which affects approximately 3,500 infants in the United States every year (â€Å"Sudden Unexpected Infant†). Babies, especially newborns are very fragile and they can get sick very easily and sometimes a small cold can result in hospitalization, but these odds can be reduced by breastfeeding because babies who are breastfed don t get sick as often as those who are formula fed. Breast milk can prevent allergies, eczema, ear infections, and stomach problems (Adler).

Clinical Health Assessment Medical

Question: Identify and write down what you consider to be therapeutic communication techniques used by the paramedic attending to Josh? Answer: Clinical Health Assessment Therapeutic communication is said to be a one to one interaction process, which concentrates on advancing emotional and physical well being of a care consumer. Nurse or paramedic staff use these communication techniques in order to support and inform patients (Balzer-Riley, 2008). The communication presented in the video is therapeutic communication, used by the paramedic attending to Josh. This is because the person actively listened to what Josh mentioned about his wrist pain. He sat facing Josh and throughout the communication he was relaxed and maintained eye contact. The paramedic shared his observations, by saying yes, your hand is swollen. He shared empathy by understood what Josh mentioned and accepted his condition and communicated his understanding. The paramedic shared hope by saying it will be all right (Med.monash.edu.au, 2015). The paramedic asked relevant question to Josh. When Josh said that he hit his hand in the gym, the paramedic further enquired how, and whether the pain is radiating or it is a sharp pain or how he is sensing the pain. To make a decision it is important for the paramedic to ask question to Josh. He asked him a question at a time, and then explored prior moving to the next question. He maintained proper pause in between each questions he asked Josh. Open ended questions help care provider to make proper decision and introduce relevant information regarding a particular situation. These are therapeutic and not common social communication technique as this involves proper medical intervention of Joshs sudden health condition. References Balzer-Riley, J.

Name Sydney Reid Essays (924 words) - Cannabis,

Name: Sydney Reid College ID: 0591992 Thomas Edison State University General AOJ-102 Section no.: Writing Assignment #1 Semester and year: Aug 2017 In this paper, we will be going over what I think is the most important crime that has a great effect on the criminal justice system of the United States of America. First, I will be mention ing why marijuana drug criminalities are the biggest plague in the criminal justice system . Next , we will talk about the positive and negative impact on the criminal justice system if marijuana were legalized everywhere . Lastly, I will go over how the Trump administration stands on marijuana and how it could affect the criminal justice system. The most significant crime that has the biggest impact on the criminal justice system , in my opinion , is marijuana drug - related crimes. Of course , this does not pertain to drug crimes that end in homicide, but simply possession or intent of selling charges of marijuana. "Marijuana arrests were about 13.6 percent more than the 505,681 violent crimes arrests mad e in 2015" (Williams, 2016). In early attempts to racially stigmatize a drug which was first known as cannabis, changing of its name were in attempts to undermine the people that consumed this drug. It was documented in the 1970's about how new drug laws targeted minority groups to achieve mass incarceration, so from the 1980's to 2009 , there was a big increase in the criminal justice system for drug related offenses. Some of the issues have since been resolved through the legalization of marijuana use in some states, and because of this move, those states are capitalizing on its profit and less law enforcement pres ence with marijuana. This , "... could become a conflict between the current presidential a dministration and the states because in the latter administration, states were given ultimate control of their recreational marijuana use laws" (Krishna, 2017). Positive impacts that marijuana legalization would have on the criminal justice system would be a gigantic increase in savings for appropriate system regarding lesser criminal arrests. "Colorado alone is estimated to potentially save $12-$40 million dollars over a year by ending arrests for marijuana possession" (Roberts, 2014). There would also be less money spent on housing inmates for short periods of time beca use of minor charges which save taxpayers' dollars. Negative impacts that marijuana legalization could have on a particular society begins with youth utilization. It is believed that over 10 percent of Colorado youth were marijuana users according to a re port by the Rocky Mountain High- Intensity Drug Trafficking Area. This has driven school- related suspensions and expulsions due to drug violations. These effects impact the criminal justice system in unforeseen ways. We cannot predict how the youth will turn out as adults, meaning, whether they stay on the legal side of marijuana use or become so addicted that they conduct more violent crimes for their vice. "It seems the long-standing tension between state marijuana law reform and federal prohibition is headed for a big confrontation " (Kamin, 2017). This statement comes from a perceptive idea because of the appointment of Jeff Sessions as attorney general. Sessions is one of the country's biggest anti-drug spokesmen. It is believed that the president is once again going back on his word because he stated that "marijuana legislature should be left to the states", but the white house press secretary Sean Spicer stated that "states , where recreational marijuana use is legal , will be subject to greater enforcement". This would mean for many unsolved answers that are currently in our criminal justice system. In turn , this would have an impact on all of the formal stages of the criminal process. This is an issue that our country faces today that some say has a slim chance of getting better with more leniencies on marijuana. Who knows where this will end up in the years to come? In conclusion, we discussed why I think marijuana drug crimes are the ones that a ffect the criminal justice system of the United States of America mostly. Also, how it was used as a targeting method in the early

Why We Laugh Essay Example

Why We Laugh Essay Humour is a subject that has attracted the attention and interest of some of our greatest minds, from Aristotle and Kant to Freud. It has also fascinated and played an important part in the work of some of the greatest writers such as Shakespeare and Oscar Wilde. However, curiously, after thousands of years spent trying to understand humour, there is still a great deal of controversy about what humour is or why something is funny. There are some interesting theories, though, on this matter. For Aristotle, comedy is based on â€Å"an imitation of men worse than the average,† of people who are â€Å"ridiculous†. Hobbes carried the same idea a bit further. He said, â€Å"the passion of laughter is nothing else but sudden glory arising from a sudden conception of some eminency in ourselves by comparison with the infirmity of others, or with our own formerly. † There is another theory that is probably the most important and most widely accepted of the explanations of humour. This theory argues that all humour involves some kind of a difference between what one expects and what one gets. One of the more interesting and controversial theories of humour stems from the work of Freud. The psychoanalytic theory of humour argues that humour is essentially masked aggression which gives us gratifications we desperately crave. As Freud wrote in his classic book—Jokes and Their Relation to the Unconscious— â€Å"and here at last we can understand what it is that jokes achieve in the service of their purpose.

His use of the word â€Å"fun† is important. He did not regard Jewish jokes as masochistic (gratification gained from pain, deprivation). Just the opposite. It might be argued that since humour is an effective way to keeping in touch with reality, Jewish humour has been intimately connected with Jewish survival. Also, humour is not some kind of an idle and trivial matter but generally enables people to gain valuable insights into social and political matters. The fact of the matter is that this seemingly trivial, inconsequential, common thing we know as humour is very enigmatic and plays a vital role in our psychic lives and in society.

Reflections - Essay Example Moreover, through evangelism, I get a better understanding on Christian challenges but derive satisfaction in making other identify with Christ. Nevertheless, the mode of evangelism defines the perception, challenges, and success in evangelism. As such, there is need to establish the most effective and less challenging strategies of evangelism. For instance, there is need to change the traditional evangelism approaches with ordinary attempts that the modern society can relate with (Henderson, 2007). Through this approach, evangelists will have an easy way in bridging the gap between the â€Å"lost† people and Jesus Christ (Henderson, 2007). Moreover, this approach will help the society to recognize salvation as a major and relevant decision in our lives. Additionally, there is need to establish the best conversation aids on evangelism for the society to understand the message spread by the evangelists (McRaney, 2003). Indeed, communication is a major factor in evangelism since evangelists seek to spread the gospel to a diverse society that requires a better understanding on the gospel for them to join Christhood. We should thus seek to remove all the barriers by adopting better communication strategies (McRaney, 2003), relating evangelism with the typical life, and use a variety of creative and natural connection po ints (Henderson,

Incident for Aids Case Study Example | Topics and Well Written Essays - 500 words

Incident for Aids - Case Study Example However, the scope ought to be widened to include other men from other races and social classes. The level of diversity among the minority groups such as the Hispanics presented a major challenge for the agency, as it could not replicate the initiatives that had been successful with the original group. This was a dire phenomenon because the epidemic was rising among gay and bisexual males from these minority groups. For instance, the level of acculturation to the American ways has a huge impact on how a man would face the stigma associated with AIDS and homosexuality. Therefore, there was need to develop different sensitive programs that would target the different groups such as the youth, recent migrants and the acculturated. Consensus building entails seeking the consent of all participants in a situation where there were differences in opinion. In formulating a Latino-oriented program, the agency consulted an expert who proposed six barriers for adoption of safer behaviour. The barriers were reduced to four after lengthy discussions, but the agency representatives still hold different opinions about the number that should be used. In order to develop consensus I would appeal to the representatives to focus on the common interest and not their agencies’ position. In this case, the common interest will be identification of the major possible barriers. The focus group must incorporate members from all the segments of the target group. Since there are many members, it is imperative that the stakeholders command respect from the other members, who must exhibit their confidence in them. It is important to select people who have a similar perception of the issues and not those who will undermine each other. A focus group should work towards creating a lasting solution for the issues. Therefore, they should provide this information: what they have learnt from other segments; what each group should do to achieve the goals; and

Executive summary Essay Example for Free

Executive summary Essay Donald, you provided a thorough discussion of what an executive summary really is. Your method of presentation of examples that are equivalent to an executive summary such as a business report or a one-verse summary from the Bible serves as a superb way for the reader to totally appreciate what you are talking about (Marydee, 2004). You also provide the technical features of an executive summary, such as the general length and the scope of such documents (Penrose et al. , 2004). However, I would also want to comment on the tone of your discussion. In your fourth and sixth paragraphs, I noticed that there were a couple of sentences that project a negative attitude among the readers of executive summaries. You mentioned in the fourth paragraph that â€Å"†¦executive summaries are designed for audiences that lack time or motivation to read the full report (Bovee et al. , 2003). † I suggest that you modify this sentence because this connotation of this phrase is not very pleasant for the reader. In the sixth paragraph, you stated, â€Å"†¦most executives habitually make quick decisions, well written executive summaries are arguably the most important information in the business report. † This phrase of yours provides an impression that executives either are not interested in reading the full report, making these individuals not as energetic as they are perceived, or that executives are very gullible because their major decisions are all based on the executive summary. The problem here with your description is that if there is a substandard executive summary that has been generated by a fresh writer, any decisions that will be made by the executive will be significantly influenced by the work produced by this immature writer. I suggest that you incorporate my comments and suggestions so that you will have an improved version of your discussion.

Calculation of Body Surface Area (BSA) for Blood Volume

Calculation of Body Surface Area (BSA) for Blood Volume CHAPTER 25 Calculation of Body Surface Area, Circulating Blood Volume,  Requirement of Blood Products Namita Mishra, Sudha Rawat, Vishva Nath Sharma BODY SURFACE AREA (BSA) Body surface area (BSA) is the area of the external surface of the body, expressed in square meters (m2). In physiology and medicine, the body surface area is the measured or calculated surface of human body. It is used to calculate metabolic, electrolyte, nutritional requirements, drug dosage, and expected pulmonary function measurements. BSA is a measurement used in many medical tasks. For many clinical purposes BSA is a better indicator of metabolic mass than body weight because it is less affected by abnormal adipose mass. Nevertheless, there have been several important critiques of the use of BSA in determining the dosage of medications with a narrow  therapeutic index  like many chemotherapy medications. USES OF THE BSA To gain an appreciation of the true required glomerular filtration rate (GFR) renal clearance is usually divided by the BSA. To calculate a better approximation of the required cardiac output as for example in children, cardiac index is used. Cardiac output = Cardiac Index / BSA Chemotherapy is often dosed according to the patient’s BSA. Glucocorticoid dosing is also expressed in terms of BSA for calculating maintenance doses or to compare high dose use with maintenance requirement. CALCULATION OF BSA It is difficult to actually measure the surface area of the human body so various calculations have been published to arrive at the BSA without direct measurement. The most widely used is the Du Bois formula: BSA = 0.007184 X W0.425 X H0.725 A commonly used and simple one is the Mosteller formula: 0R BSA = ( [ H X W]/ 3600)1/2 Where H = Height W = weight for example : Patient’s weight = 65 Kg Patient’s height = 165 cm BSA = ([65 X 165])/3600)1/2 BSA= 1.72 m2 Recently, a weight-based formula was validated in the pediatric age group that does not include a square root, making it easier to use. It is [4Wkg+7]/[90+Wkg]. AVERAGE VALUES Average BSA for various weights: WEIGHT (Kg) BSA (m2) 1.5 4 0.13 – 0.26 4.1 – 9 0.26 – 0.48 9.1 – 14 0.48 – 0.56 14.1 – 20 0.56 – 0.71 20.1 – 26 0.71 – 0.84 26.1 34 0.84 – 1.0 34.1 – 50 1.0 – 1.4 50.1 66 1.4 – 1.63 Over 66.1 Over 1.63 EFFECTIVE CIRCULATING VOLUME Blood volume is the volume of blood (both red blood cells and plasma) in the circulatory system of any individual. A typical adult has a blood volume of approximately between 4.7 and 5 liters, with females generally having less blood volume than males. Blood volume (BV) can be calculated given the hematocrit (HCT; the fraction of blood that is red blood cells) and plasma volume (PV): BV = PV/ (1-HCT) Diagnostic technologies are commercially available to measure human blood volume. A recent radio nucleotide study called BVA (Blood Volume Analysis)-100, provides a measure of Red Blood Cells and Plasma with 98% accuracy. BLOOD VOLUME ESTIMATION WEIGHT (kg) BLOOD VOLUME ( ml/kg) New born to 10 85 11 to 20 80 21 to 30 75 31 to 40 70 Above 40 65 CIRCULATING VOLUME OF THE CPB CIRCUIT PRIMING VOLUME: the minimum amount of fluid (hemic or non hemic fluid) used to de- air the complete cardiopulmonary bypass (CPB) circuit is called priming volume or the circulating volume of CPB circuit. Priming of the CPB circuit is an important task for the perfusionist. Generally the main objectives of priming are: To deair the CPB circuit To check for any leaks in the circuit To check for any mistake in the assembling of the circuit To meet the need for the extra volume required to prime the CPB circuit as the patient’s blood volume is not sufficient enough to prime the CPB circuit. For achieving sufficient hemodilution. It is a standard practice to use a non blood CPB prime because of the benefits of hemodilution and concerns about blood borne diseases. The total priming volume is determined by the hardware selected for the circuit to be employed. Following are the tables showing the volume required to de-air various oxygenators, arterial filters and tubing. CPB CIRCUIT AND TOTAL PRIMING VOLUME WITH VARIOUS WEIGHT GROUP Weight Group (Kg) Boot Size (inches) Venous line Size (inches) Arterial line Size (inches) Total Priming Volume (ml) 0-4 1/4 1/4 1/4 450 4.1-8 3/8 1/4 1/4 600 8-12 3/8 3/8 1/4 800 12.1-25 3/8 3/8 3/8 1100 >25 1/2 1/2 3/8 1800 TUBING SIZE WITH VOLUME (ml/feet) SIZE (inch) VOLUME (ml/feet) 3/32† 1.8 1/8† 2.5 3/16† 5 1/4† 9.65 3/8† 21.7 1/2† 38.6 SPECIFIC CONSIDERATIONS: In cases where patient is deeply cyanotic the size of the oxygenator and tubing size is selected keeping in mind the requirement of higher degree of hemodilution and higher requirement of arterial blood flows because of the presence of large (or major) aorto-pulmonary collaterals (MAPCA’s). MAPCAs arise from the aorta or its large branches and supply blood to the pulmonary arteries, because of blockade of the main pulmonary arteries. These MAPCAs ‘steal’ part of the cardiac output of the aorta and this results in reduced systemic perfusion and thus increased pump flows are required during CPB in cyanosed patients with MAPCAs to compensate for this ‘stolen’ cardiac output. CACULATION OF BLOOD AND BLOOD PRODUCT REQUIREMENT The hematocrit (HCT), also known as packed cell volume (PCV) or erythrocyte volume fraction (EVF) is the volume percentage (%) of red blood cells in blood. It is normally about 45% for men and 40% for women. It is considered an integral part of a person’s complete blood count along with hemoglobin concentration, white blood cell count, and platelet count. Haemoglobin concentration is reduced as a normal consequence of CPB with hemodilution. Thus the hematocrit that will result from the hemodilution caused due to priming volume of the CPB circuit should be determined. Several calculations are required to assess hemodilution and blood product requirements. To determine the effects of hemodilution, the volume concentration formula is used. C1 X Pt BV = C2 X TVon CPB Where Pt BV = patient’s blood volume ( patient’s body weight X blood volume factor) TVon CPB = total volume on CPB (total priming volume + patient’s total blood volume) C1 = Pre bypass hematocrit of the patient (%) C2 = calculated hemodilutional hematocrit (%) A decision must be made initially regarding the desired hematocrit during cardiopulmonary bypass. Based on the results of the randomized clinical study from Children’s Hospital, Boston ,it seems reasonable to consider a hematocrit of 25% to be the minimal acceptable hematocrit for any cardiopulmonary bypass condition. When the desired hematocrit has been selected the amount of bank blood that must be added to the prime should be calculated. Prime RBC vol = {[C3]x[Pt BV + PV]} {Pt RBC vol} Where Prime RBC vol = volume of blood required in prime C3 = desired HCT on bypass Pt BV = patient’s blood volume ( patients body weight X blood volume factor) PV = total priming volume of the CPB circuit to be used Pt RBC vol = patient’s blood volume X patient’s pre bypass hematocrit For example: Patient’s weight = 5 Kg Pre bypass hematocrit (C1) = 40% Patients blood volume (Pt BV) = 5 X 85 = 425 ml (85 is blood volume factor for 5 Kg) PV (total priming volume of the CPB circuit to be used) = 600ml TVOn CPB = (600 + 425) = 1025ml Calculated hemodilutional HCT (%) (C2) = C1 X Pt BV / TVon CPB = 40 X 425 / 1025 = 16.5 % 16.5 is the hematocrit on bypass. If there is a certain desired hematocrit, then to achieve that hematocrit, the amount packed RBCs if needed for the same patient can be calculated as follows: C3 (desired HCT) = 30 % Pt BV = 425 ml PV = 600 ml TV On CPB = (Pt BV + PV) = (425 + 600) = 1025 ml Pt RBC vol = 425 X 0.40 = 170 Prime RBC vol = {[C3]X [Pt BV + PV]}-{Pt RBC vol} = {[0.30] X [1025]}-{170} = 137.5 Volume of RBCs needed in prime = 137.5 The hematocrit of packed RBCs is 70% thus 137.5/0.70 = 196 ml 196 ml of packed RBCs are needed to achieve a hematocrit of 30%. Thus, 196 ml of the clear prime fluid is removed from the priming volume to account for the added packed RBCs. Therefore the calculation of priming volume now has 196 ml of packed RBCs and 404 ml of prime (crystalloid or colloid). In some cyanotic cases where the patient’s pre bypass hematocrit is more, the blood is diluted to obtain an optimal hematocrit during cardiopulmonary bypass in order to decrease the viscosity of the blood to improve tissue perfusion and to prevent hemolysis. Thus the effect of priming fluid added to dilute the blood can also be calculated as: TVon CPB X C4 = TVon CPB 1 X C5 WHERE TVon CPB = total volume on CPB (total priming volume + patient’s total blood volume) = 1025ml C4 = Hematocrit (of cyanotic patient) on bypass = 0.60 TVon CPB1 = total volume on CPB after adding 500 ml of priming fluid to the CPB circuit. TVon CPB1 = (1025 + 500) = 1525 ml C5 = the new (affected) Hematocrit Thus C5 = (1025 X 0.60) / 1525 = 0.40 40 % is the new hematocrit achieved after adding 500 ml of priming fluid. FIBRINOGEN A critical consideration is plasma fibrinogen dilution. Normal plasma fibrinogen levels are 150-400 mg./dL. The infant/ pediatric patients relative low blood volume with priming requirements of the ECC circuit causes the fibrinogen concentration to be adversely diluted. During CPB, it is desirable to maintain the plasma fibrinogen concentration above 100 mg./dL. in order to prevent impairment of post-CPB hemostasis. Given an example of a 5 Kilogram patient with blood volume of (5 x 85) 425 ml, pre bypass hematocrit of 55%, hematocrit on CPB of 25%, priming volume of 800ml of the circuit to be used for CPB and fibrinogen level of 275 mg/dl. To calculate the effect of priming, patient’s plasma volume is calculated by following formula: BV = PV/ (1-HCT) PV = (1-HCT) X BV Thus PV = (1-0.55) X 425 = 191ml PV = 191ml Patient’s fibrinogen = 191 X 275 mg/100ml = 525 mg Number of milligrams required = (425 + 800 ) X (1.00-0.25) = 9.19 dl If the goal is 100mg/dl, then 919 mg of fibrinogen are needed. Amount of fibrinogen to be added = 919 – 525 = 394mg. 394 mg of fibrinogen must be added to the prime to achieve a goal of 100 mg per dl. FFP usually contains 200 mg of fibrinogen per dl. Thus ml of FPP needed = (394/200) X 100 = 197 ml. Now for the calculation of priming volume the 197ml of the prime fluid (crystalloid or colloid) is replaced by FPP. Thus the clear prime volume becomes 603ml. Suggested reading Jianfeng Wang, Eiji Hihara. A unified formula for calculating body surface area of humans and animal.

Effect of Slavery on Feminism in the Beloved Novel

This chapter presents a review of related literature and studies that serving as a background and frame of preference upon which conceptual framework was formulated. This material gave much background and information for the present study. Related Literature (12 page single space) p 7-21 2. 1 Slavery 2. 1. 1 Timeline of Significant Events. The slave trade had a long history.The first importation of slaves by the Spanish vessels from Africa to America took place in 1522. The first African Slaves arrived in Virginia, USA in 1619. The English colonies start the lawful establishment of slavery in 1660 which included the United States.The start of the big waves of slave importations into the English colonies from Africa occurred in 1700. The slaves start to outnumber the English Americans in 1720. The Quakers start to fight against the evils of Slavery in 1750. The French and Indian War resulted to the expulsion of the French army from many parts of North America for ten years starting in 1753. The United States war for independence from Great Britain started in 1775 in the war of Lexington and Concord. The United States finally declared that it wanted to be independent from the Great Britain on July 9, 1776 .And, the Continental Congress of the United States formally approved their Articles of Confederation on July 9, 1778. And, Massachusetts and Pennsylvania finally abolished the practice of slavery. Great Britain and the United States formally signed the Treaty of Paris agreeing to stop the independence war between the two countries and to recognize the United States as a new nation. And, the Continental Congress sends the new Constitution to the state for ratification on September 28, 1783. George Washington is proclaimed as the first president of the United States on April 30, 1789.The Bill of Rights that contained the first ten amendments were approved by more than three fourths of the United States territory and becomes part of the United States Constitution. The United States bought Louisiana from France for fifteen million U. S. dollars. And the members of the United States formally made a law banning the importation of slaves into the United States . Further, the White Churches start their religious outreaches to the African American slaves. The United States quelled the revolt orchestrated by Nat Turner in Virginia.Abraham Lincoln was chosen by the people as the sixteenth president of the United States on March 4, 1861. General Robert Lee’s Confederate army formally surrenders and ends the Civil War on April 9, 1861. The thirteenth Amendment was finally approved by the United States Congress. Lastly, the United States Congress approves with finality the fourteenth Amendment of the United States Constitution. This amendment gives automatic citizenship to the slaves. This amendment also punishes those states that do not comply in with the Amendment to remove slavery by taking away the rebelling state’s representation in Congress.Also, all free men are given the right to vote under the fifteenth Amendment to the United States Constitution The Beloved novel also had a theme entitled slavery. Slavery is described by the novel’s author as commonplace. This means that the people who have slaves are considered normal people. The people during this time period accept that slavery is an institution and its philosophy and mindset affects the lives of many people in the slave –prevalent parts of the United States. Consequently, slavery had its advantages and disadvantages. There are also good owners of slaves as well as abusive owners of slaves.Beloved speaks of Garners. They are the owners of the slaves like Sethe. They were very kind to the African American slaves. In return, the slaves like Sethe and Paul D. , another slave, respected the Garners. This happy cooperation between the Garners and the slaves came to an abrupt end when the Garners died. This novel describes the years before the C ivil War and the years after it. Morrison’s lyrical narrative coherently weaves together the supernatural and the tangible giving a literary masterpiece that pours out a dazzling achievement resulting to a spellbinding reading activity .They were replaced by the cruel leadership of the Garner replacement. The replacement was a man known only as school teacher. Paul D later stated that their happy home would only last as long as the Garners were alive. This was definitely true. Paul D. further reiterated that their happy home under the Garners would be shattered upon his death. The novel also dictates that the Garners are for against the practice of slavery. However, the novel identifies the slaves as just simple playthings or workers who were manipulated by the Garners to feed their fantasies and wants with the slaves as instruments.In a simple to read manner, Beloved author Morrison wants to paint a picture in the minds of the Beloved readers how big the problem of slavery i s. Morrison also indirectly gives clues as to how widespread and evil the slave trade was during those fateful time periods. The author, Morrison, also emphasizes that there are some ways to eradicate slavery. In the Bodwin home, there is a statue of an African American child. The statue has on it an inscription that reads â€Å"At Yo Service†. 2. 1. 2 US. WAR OF INDEPENDENCE.As a backgrounder to this research, George Washington led the Continental Army to defeat the Kingdom of Great Britain in the American Revolutionary War. The war took place between 1775 and 1783. He led the American Army to defeat the British forces in Boston. However, he was later defeated in New York. He counter attacked by crossing across the Delaware River into New Jersey. He won in the battle there because the British forces were caught by surprise. Next, the American forces overrun the two biggest British forces in Saratoga and Yorktown.George Washington united the different sectors of the colonial American pioneers in an astute manner. He negotiated with their new French allies and Great Britain to end its involvement in wars outside the American colonies in its Treaty of Neutrality in 1793 . Further, he was instrumental in a Central American government, the imposition of a national tax system and a central bank. He entered into an agreement with Britain to stop any future war between both of them. George Washington was one of the authors of the United States Constitution.He is famous for the line â€Å"four score and seven years ago our fathers brought forth on this continent a new nation, conveived in Liberty, and dedicated to the proposition that all men are created equal. † This Abrahan Lincoln speech was delivered on the biggest and bloodiest battlefield of the civil war –Gettysburg. This speech brings the civil war combatants, supporters and relatives to the stark reality that George Washington has painstakingly created a new nation, United States. This sp eech was made by the current civil war President Abraham Lincoln during the burial of dead soldiers in a mass grave in Gettysburg .George Washington had pooled together the entire people in the colonies to rally behind his popularity towards independence. He expertly blended the different interests and political hopes of the people and the Continental military into one solid and strong band of brothers. He had been the secret ingredient that united the soldiers then. He did things by helping the different sectors of the military, the states as well as the Continental Congress to settle their differences amicable. He was skillful as a planter, politician and the first United States President .George Washington was very instrumental in creating a free United States with the Declaration of Independence as follows: â€Å"We hold these truths to be self evident: that all men are created equal; that they are endowed by their Creator with certain inalienable rights; that among these are l ife, liberty, and the pursuit of happiness. † 2. 1. 3 Renaissance literature on Slavery in the 1800s. Many of the people in the South were changing starting in the year 1824. This precipitated from the passing of the Long Virginia hegemony. The humanitarian thought of the prior generations were slowing being replaced by new thoughts.The people were now more interested in the economic turn of events in their lives and their community. The people of the South kept holding on their policy on slavery despite the trend in the North to free the slaves. For, the Southern states’ main economic activity was farming. And the slaves were very useful in the plantations. However, the Northern part of the United States was more industrialized. Thus, the Northerners felt that they no longer need the services of the slaves. The shift from the prior Jefferson to Calhoun was inevitable to the Southerners.This means that the current economic realism had completely eroded the prior humanit arian idealism . There was no stopping of the change from small gentlemen planters over the inarticulate Southern yeomanry. The Southern mind was now focused on the assertion of Aristocratic idealism. The South had abandoned the Jefferson theories of equalitarianism that had been deeply entrenched in the people’s minds from Kentucky to as far away as Georgia. The South had abandoned the agrarian theories of John Taylor and the older Virginian population. The imperialist mind of the South was located in Charleston.The strength of the South could be found in the black belt. This belt started from South Carolina to the East and Texas in the West. For, there were more slaves than the whites in these areas. The philosophical theories of imperialism had spread like wildfire in the Southern American regions. The literature of the eighteenth century was focused on the plantations. Literary pieces during this period include the Anarchiad and Echo of Harford Wits. Other literary pieces included the private letters of an indignant gentleman . American literature during the 1800s was symbolic in nature.This was the style of American literature expert Charles Feidelson Jr. American writers during the accounting period Emerson, Whitman, Melville and Hawthorne tried to understand the American world in terms of symbols. They felt that this was the best way to unveil the significance of the phenomenal world they were living in. Feidelson felt that the rage to interpret American life was the inherent quality needed to produce quality American Literature in the 1800s. Here, the Puritans of this time period were too engrossed in the study of the meaning of self, world and the Puritan hermeneutic typology.The people here were busy trying to think what God’s plan for United States continent was for the coming years. Another American literature during this time period was The Rhetoric of American roman Romance by Evan Carlton. Carlton used Davitt Bell’s concept of starting a literary mastery with the theme of relation . 2. 2 Characters of the Story 2. 2. 1 Sethe Sethe is the star of the novel. The entire novel revolves around her (Morrison 1). It also talks of the people who are her children, her lover and her relatives. She is a slave in Kentucky. She escaped from the Garner residence named Sweet Home because they had died.The new slave owner, the school teacher, was too harsh on them. Thus, Sethe and the other slaves could not bear the inhuman treatment of the school teacher thus forcing them to fight back. This fighting back was in the form of running away. Sethe and the other slaves had to run away to freedom. However, Sethe was discovered barely a month after her bold escape. Upon being caught, Sethe slit the throat of her child, Beloved, in order to keep her from suffering under slavery when she grows up to womanhood. Sethe stands out from the normal African American slaves because she is bold and independent minded.This is what insp ires her kind. She even proudly stated to Paul D. that she will not run away from things on this earth. However, Sethe’s life has no direction. She spends most of her waking hours in her home, 124, trying to forget her past where she killed her own daughter, Beloved, and she was raped by a white American. This murder occurred when escaped Sethe was caught by the white Americans. Sethe would always miss her Beloved child even after killing her. Two men caught Sethe in Mother Baby Suggs house and took her milk from her. Thus, she was not able to feed her human milk to her children .2. 2. 2 Paul D. Paul D was an African American slave in Kentucky. He escaped from his white owners only after Sethe successfully made her get away. Paul D. continuously tried to run away for eighteen years but he was caught each time. And, he finally reached Sethe’s front steps in Cincinnati after his last escape try was successful. Paul D. also had a past that he rather forget because he cons idered it as a nightmare. He locks up this sad part of his past in his tobacco tin part of his heart. For, his secretive past horror was that he was often imprisoned in a cube that lay in a ditch.The reincarnated Beloved seduces Paul D. and tells him to accept his past as a normal part of life. Beloved aids him to finally lay his heavy load of a horrible past to rest. He is steadfast in his plan not to love anything in life too much because it would be only temporary. Martin Bidney stated that â€Å"I want to show that one of Morrison's chief goals in Beloved is to rethink and transform major British romantic poets. By taking a romanticist tour of Beloved, we can see with what startling originality she reshapes the literary past† . 2. 2. 3 Beloved Beloved is the third child of Sethe, the main character of the novel.She was murdered by Sethe at the age of one. She stayed on as a ghost for the next twenty years in 124. She is reincarnated on her twenty first year. However, she has the mind of the child. He return was due to her desire to be caressed by her mother and to avenge her death at the hands of Sethe. She tries to comprehend why her own mother would kill her. She symbolizes the many African Americans killed because of the color of their skin. For, sixty million Africans that were kidnapped and forcibly packed like fishes in the very tight ocean going vessels to be sold into slavery.Beloved had come back from the other world to address such hotly contested issues as justice for the slaves, morality and slavery . One Toni Morrison’s intentions for this novel was that the story would not end with the Paul D. rather, she wants this story to be told and retold so that many people from the current and future generations will not forget the slave past of African Americans. For, Paul D. finally laid to rest his nightmare as a former slave by accepting it as part of his heritage. Beloved successfully opened the eyes of Paul D. to finally accept his past and to move on . 2. 2. 4 Baby Suggs Baby Suggs is Sethe’s mother in law.She is the mother of her husband, African American Halle. The novel states that Baby Suggs had died eight years ago. Baby Suggs was given freedom by her white American owners. She was happy that her owner informed that she is a free woman. She feels that that she now owns the different parts of her body. She encouraged her fellow African Americans to love themselves for what they are. She spread the word that her fellow African Americans should endure all that the White Americans placed on them and everything would turn out fine . 2. 2. 5 Denver She is the living daughter of Sethe. She felt that the arrival of Paul D.has left her alone in a small corner of her mother’s home. Paul D. and Sethe often stayed to make love. Sethe feels that three is crowd because her mother and Paul D. were too busy sharing love with each other. And, Sethe feels that the boys and the girls of her time did not want to be her friends. She does not feel lonely because her lonely hours are spend conversing with her only friend. This friend is the ghost of Beloved. However, the ghost of Beloved is finally driven off by Paul D. 2. 2. 6 Howard & Buglar They are the two other children of Sethe. They ran away from Sethe when they were still thirteen years old . 2. 2.7 Stamp Pride Stamp Pride is another African American slave. He had to endure his horrible past. This past was his that he was forced to give his wife away to the white Americans so that she could be their sex toy. Stamp Pride worked actively against the forceful taking of his wife . 2. 3 Racism Beloved focuses on racism. The African slaves are classified as animals by the people during this time period. The novel focuses on the school teacher. The school teacher likens the slaves not as a human being but only as an animal. This means that they are just like the pet dogs and the working horses that Caucasians own in their farms.As animals, the Caucasian owners can do whatever they please with their property. And, the slaves are classified as property that the owners definitely will be useful in the farms of the slave states especially in the Southern United States territories. The African Americans are portrayed by the Beloved novel literally as having the same five senses that the Caucasian owners have. The slaves also have the senses of sight, hearing, smelling, touch and taste . Evidently, the novel Beloved emphasizes that the African American slaves are also human beings and should not be treated like ordinary cats, dogs, horses or any other work animals.The novel is replete with voluminous pages showing that the African Americans are torn between fighting for their freedom from slavery or to just accept the stark reality that they were born to be harnessed just like pet dogs and horses. Also, the tune period of the story is very volatile as evidenced by the thousands who have died on both the Union side under Ro bert E. Lee and the Confederate side under General Ulysses S. Grant. The civil war was fought by the Union soldiers because they wanted to free the slaves.The Confederate soldiers fought the war because they felt they had to break away from the United States and form a separate nation where slavery is allowed . The novel raises the issue of racism throughout the entire novel. It defines what freedom is to the slaves. Baby Suggs felt that she was free. However she had to right to privacy and property. For, the White Americans could barge into her home and search her place anytime of the day without need to ask for her permission. This what the white Americans did when they stormed her place to search for the escaping Sethe who brought along her children four children.Also, the Paul D. was not allowed to love whatever he wanted to love due to African American lineage. Racism is very evident because the African Americans had to wait in line for the white Americans to finish their groce ry purchases before they were allowed to enter and buy grocery items. The author, Morrison, emphasizes that being a free slave does not only mean NOT belonging to any white American. Racism has caused a break up of the African American families. For, the children of the African Americans would be taken away from them by their owners never to be seen again.This is due to the fact that Slaves are the property of their masters . 2. 4 Kentucky the 1800s Kentucky in the 1800s was a time where owning a slave is normal human activity. Also, many slave rebellions cropped up during this time period. People like John Trumbull had to find ways to fight out any revolt from their slaves . CHAPTER III RESEARCH DESIGN AND METHODLOGY This chapter presents and discusses the method of research used and the procedures utilized by the researcher in this study. It likewise includes the sources of data and the treatment of data. Methodology of the studyThis investigation adopted the compare and contrast qualitative research method as this is the most appropriate way in determining the effect the type of business to the success of the business. In addition, the quantitative approach was included to complement the qualitative part of this research. The Archival Research is defined by Bordens, Kenneth S. , and Abbott, Bruce B. , (1999) as a non-experimental strategy that involves studying existing records. These records can be historical account of events, census data, court records, police crime reports, or any other archived information.This qualitative study is divided by two parts. They are: 1. Compare Motherhood and Feminism in Beloved 2. Contrast Motherhood and Feminism in Beloved. And, the quantitative study focused on interviewing twenty persons who have read the Beloved novel. The researcher took pains in reading, searching and analysis of the different parts of this study. The researcher examined the comparison and contrast of Motherhood and Feminism in Beloved. The historic al background is one of the main focus of this study including their success.The final phase was the analysis, presentation and the drawing of the conclusions and the recommendation. RESEARCH INSTRUMENT The primary research instrument and technique was used in the gathering of data for this study. In addition, the researcher used secondary sources taken from books and journals. These secondary sources had guided the researcher to broaden the point of understanding specifically the effect of Motherhood on Feminism in Beloved. The analysis of variance was used to compare the different topics found in Beloved and the respondents answers grouped according to Age, Gender and Highest Educational Attainment.The formula for Analysis of Variance includes Y i = e i where e i is N(0, ? 2 ) [2. 1] RESEARCH PROCEDURE The researcher seeks the primary as well as secondary materials as the best way to examine the effect of Slavery on Motherhood and Feminism in the Beloved Novel. After a through stu dying, reading and scrutinizing the different data, it is best to use the secondary sources as a basis for company business analysis and then coming up with the output – Results of the Effect of Slavery on Motherhood and Feminism in the Beloved Novel.

What is Software Development Life Cycle? (SDLC) (2 mks) System Development Life Cycle (SDLC) is the overall process of developing information systems through a multi-step process from investigation of initial requirements through analysis, design, implementation and maintenance. b) Draw a diagram for pure waterfall life cycle. (5 mks) [pic] c)Explain the different phases involved in waterfall life cycle. (8 mks) Phase I – Modeling Phase In this phase we view the software product as part of a larger system or organization where the product is required. This is basically a system view where all the system elements are created. Phase II – Software Requirements Analysis Here we have a phase where the requirements are gathered. The information domain for the software is understood. The function, behaviour, performance and interfacing of the software are determined. The requirements of the software and the customer are decided upon. Phase III – Design This determines the data structures, the software architecture, the interface representations and the procedural (algorithmic) detail that goes into the software. Phase IV – Code Generation Here the actual programming is done to obtain the machine code; it is an implementation of the design. Phase V – Testing The testing is a process that goes hand in hand with the production of the machine code. There are a number of testing strategies. First unit testing is done and then integration testing. Alpha testing is to see if the software is as per the analysis model whereas beta testing is to see if the software is what the customer wanted. Phase VI – Installation The software is released to the customer. Phase VII – Maintenance This is the largest phase of the software life cycle. Maintenance can be of different types: to modify the software as the requirements of the customer evolve, to remove the residual bugs in the software etc. 2)What is feasibility study? What are the contents we should contain in the feasibility report? (5 mks) A feasibility study is an initial look at an existing information processing system to decide how it might be computerized or improved. The contents that a feasibility report are: †¢ A statement of purpose of the system. †¢ A definition of system scope. †¢ A list of deficiencies of the current system. †¢ A statement of user requirements. The cost and benefits of development. †¢ A conclusion and recommendations. 3)What are the purposes of Data Flow diagrams, Entity-Relationship diagrams? Give an example diagram of each. (10 mks) Data Flow Diagrams Data Flow diagrams are a means of representing a system at any level of detail with a graphic network of symbols showing data flows, data stores, data processes, and data sources/destinations. The purpose of data flow diagrams is to provide a semantic bridge between users and systems developers. The diagrams are: †¢ Graphical – Eliminating thousands of words; Logical representations – Modeling WHAT a system does, rather than physical models showing HOW it does it †¢ Hierarchical – showing systems at any level of detail; and †¢ Jargonless – allowing user understanding and reviewing. [pic] Entity Relationship Diagram E-R Diagram is a graphical representation of the data layout of a system at a high level of abstraction. It defines data elements and their inter-relationships in the system [pic] 4)What is data modeling? Give 5 examples for data modeling. (5 mks) Data modeling is the act of exploring data-oriented structures. Like other modeling artifacts data models can be used for a variety of purposes, from high-level conceptual models to physical data models. From the point of view of an object-oriented developer, data modeling is conceptually similar to class modeling. With data modeling you identify entity types whereas with class modeling you identify classes. Data attributes are assigned to entity types just as you would assign attributes and operations to classes. Examples for data modeling include: †¢ Entity-Relationship diagrams †¢ Entity-Definition reports †¢ Entity and attributes report †¢ Table definition report Relationships, inheritance, composition and aggregation. 5)What is the difference between SRS document and design document? What are the contents we should contain in the SRS document and design document. SRS Document SRS document is a contract between the development team and the customer. Once the SRS document is approved by the customer, any subsequent controversies are settled by referring the SRS document. SRS document defines the customer’s requirements in terms of Functions, performance, external interfaces and design constraints. SRS Includes: †¢ Functional †¢ Non functional User †¢ Interface †¢ System Design Document The purpose of a design is to describe how the enhancements will be incorporated into the existing project. It should contain samples of the finished product. This could include navigational mechanism screenshots, example reports, and component diagrams. Design Includes: †¢ E-R Diagrams †¢ Data flow diagrams †¢ Data Dictionary 6)Explain all the phases involved in the implementation phase. (10 mks) Conduct system Test In this test software packages and in – house programs have been installed and tested, we need to conduct a final system test. All software packages, custom- built programs, and many existing programs that comprise the new system must be tested to ensure that they all work together This task involves analysts, owners, users, and builders. Prepare Conversion Plan On successful completion of system test, we can begin preparations to place the new system into operation. Using the design specifications for the new system, the system analyst will develop a detailed conversion plan. This plan will identify Database to be installed, end – user training and documentation that needed to be developed, and a strategy for converting from the old system to the new system. The conversion plan may include one of the following commonly used installation strategies 1)  Abrupt Cut-over 2)  Parallel Conversion 3)  Location Conversion 4) Staged Conversion Install Databases In the previous phase we built and tested the database. To place the system into operation we need fully loaded databases. The purpose of this task is to populate the new systems databases with existing database from the old system. System builders play a primary role in this activity. Train Users Converting to a new system necessitates that system users be trained and provided with documentation that guides them through using the new system. Training can be performed one on one; however group training is preferred. This task will be completed by the system analysts and involves system owners and users. Convert to New System Conversion to the new system from old system is a significant milestone. After conversion, the ownership of the system officially transfers from the analysts and programmers to the end users. The analyst completes this task by carrying out the conversion plan Recall that the conversion plan includes detailed installation strategies to follow for converting from the existing to the new production information system. This task involves the system owners, users, analysts, designers, and builders. 7)List and explain different types of testing done during the testing phase. (10 mks) Unit Involves the design of test cases that validate that the internal program logic is functioning properly, and that program inputs produce valid outputs. All decision branches and internal code flow should be validated. Unit testing involves the use of debugging technology and testing techniques at an application component level and is typically the responsibility of the developers, not the QA staff. Integration As the system is integrated, it is tested by the system developer for specification compliance. †¢Concerned with testing the system as it is integrated from its components †¢Integration testing is normally the most expensive activity in the systems integration process †¢Should focus on: †¢Interface testing where the interactions between sub-systems and components are tested †¢Property testing where system properties such as reliability, performance and usability are tested System Testing the system as a whole to validate that it meets its specification and the objectives of its users. The testing of a complete system prior to delivery. The purpose of system testing is to identify defects that will only surface when a complete system is assembled. That is, defects that cannot be attributed to individual components or the interaction between two components. System testing includes testing of performance, security, configuration sensitivity, startup and recovery from failure modes. Involves test cases designed to validate that an application and its supporting hardware/software components are properly processing business data and transactions. System testing requires the use of regression testing techniques to validate that business functions are meeting defined requirements. Black Box This is testing without knowledge of the internal workings of the item being tested. For example, when black box testing is applied to software engineering, the tester would only know the â€Å"legal† inputs and what the expected outputs should be, but not how the program actually arrives at those outputs. It is because of this that black box testing can be considered testing with respect to the specifications, no other knowledge of the program is necessary. For this reason, the tester and the programmer can be independent of one another, avoiding programmer bias toward his own work. White Box Also known as glass box, structural, clear box and open box testing. White Box is a software testing technique whereby explicit knowledge of the internal workings of the item being tested are used to select the test data. Unlike Black Box testing, white box testing uses specific knowledge of programming code to examine outputs. The test is accurate only if the tester knows what the program is supposed to do. He or she can then see if the program diverges from its intended goal. White box testing does not account for errors caused by omission, and all visible code must also be readable. 8)List and explain all the phases involved in the construction phase. (10 mks) Build and Test Networks †¢ In many cases new or enhanced applications are built around existing networks. If so there is no problem. †¢ However if the new application calls for new or modified networks they must normally be implemented before building and testing databases and writing or installing computer programs that will use those networks. This phase involves analysts, designers and builders †¢ A network designer and network administrator assume the primary responsibility for completing this task. Build and Test Databases †¢ This task must immediately precede other programming activities because databases are the resource shared by the computer programs to be written. If new or modified databases are required for the new system, we can now build and test those databases. †¢ This task involves system users, analysts, designers, and builders. †¢ The same system specialist that designed the database will assume the primary responsibility in completing this task Install and Test New Software Packages †¢ Some systems solutions may have required the purchase or lease of software packages. If so, once networks and databases for the new system have been built, we can install and test the new software. †¢ This activity typically involves systems analysts, Designers, builders, vendors and consultants. Write and Test New Programs †¢ In this phase we are ready to develop any programs for the new system. Prototype programs are frequently constructed in the design phase. However, these prototypes are rarely fully functional or incomplete. This task involves the system analysts, designers and builders. 9)What is data conversion? Why is it necessary? Data Conversion is the changing of the data structure to accommodate new or different needs for the data. Different operating systems have different application software, and each application normally has its own internal way of saving data. There are some standards such as CSV files for databases and RTF files for word processing text, however, these are few and far between and often only save the basic information rather than the full structure. 10)What is change management? Computer based systems are dynamic. As the business Environment changes, there is a need of some changes to the information system. The changes occur not only during the study, design, and development phases of the life cycle of the system. In this process there are two elements that are essential to the management of change. †¢ The performance review board, which can make management–level decisions about system modifications. †¢ Baseline documentation, which can be referred to, to determine the extent and impact of proposed modifications. 11)What is user acceptance testing? Explain different testings in user acceptance testing. Why is it necessary? User Acceptance Testing is a phase of software development in which the software is tested in the â€Å"real world† by the intended audience. Different testings are: Alpha Testing Alpha testing is the software prototype stage when the software is first able to run. It will not have all the intended functionality, but it will have core functions and will be able to accept inputs and generate outputs. An alpha test usually takes place in the developer’s offices on a separate system. Beta Testing The beta phase of software design exposes a new product, which has just emerged from in-house (alpha) testing, to a large number of real people, real hardware, and real usage. Beta testing is not a method of getting free software long-term, because the software expires shortly after the testing period. User acceptance testing is used to know if the system is working or not (both clients ; in-house) 12)What are functional and non-functional requirements? Functional †¢ How the system should react to the particular inputs †¢ How the system should behave to the particular situations †¢ What the system should not do Non functional †¢ Constraints on the services or functions †¢ Time constraints †¢ Constraints on the development process 13)Explain the steps involved in the prototyping 1. Define the goal and purpose of the prototyping. 2. Make plans for iterations (number, range) and evaluations (dates). 3. Transform the conceptual design to a first outline of the user interface and a first synopsis for the users’ information. 4. Design the paper prototype. 5. Let domain experts review the paper prototype regarding completeness and correctness. 6. Test the prototype’s usability.

MBA 711 CVP Project Essay MBA 711 CVP Project Essay 1. What are some examples of overhead costs that are incurred by Toll Brothers? Overhead costs can be anything that is that is not associated with direct materials or direct labor (Noreen-Brewer 2nd Ed, pg.176). As stated Toll Brothers, headquartered in Horsham, PA,. is in the business of designing, building, marketing, and arranging financing for single family detached and attached home in luxury residential communities (10K,pg.1). Some of these overhead costs would include operations of (10k, pg.2): Land development Architectural Engineering Mortgage Title Landscaping Security monitoring Lumbar distribution House component assembly Manufacturing They also develop, own and operate golf courses and country clubs associated with the master planned communities they work on and even invest in joint ventures to develop land for the sole use of the venture participants. All of the above will amount to overhead costs that must be covered under the company overhead. â€Å"We own a manufacturing facility of approximately 300,000 square feet located in Morrisville, Pennsylvania, a manufacturing facility of approximately 186,000 square feet located in Emporia, Virginia and a manufacturing facility of approximately 134,000 square feet in Knox, Indiana.†(10K,pg.17) Many of these costs are fixed and involved employment of supervisors and managers that work on salary which also add to the overhead costs. â€Å"We lease, from an unrelated third party, a facility of approximately 144,000 square feet located in Fairless Hills, Pennsylvania. At these facilities, we manufacture open wall panels, roof and floor trusses, and certain interior and exterior millwork to supply a portion of our construction needs. These facilities supply components used in our North, Mid-Atlantic and South geographic segments. These operations also permit us to purchase wholesale lumber, plywood, windows, doors, certain other interior and exterior millwork and other building materials to supply to our communities. We believe that increased efficiencies, cost savings and productivity result from the operation of these plants and from the wholesale purchase of materials.†(10k,pg.17) The equipment used for the manufacturing, property taxes, factory insurance, depreciatio n of property value and utilities required to run the company will also contribute. Moreover, direct land acquisition, development, construction costs, costs with interest, real estate taxes and direct overhead related to development and construction are contributing factors to overhead.

McGraw-Hill. Week 3: Discussion Team 1 ______________________________________________ Managerial Accounting (MKTG711) September 13, 2013 Question #1: Would Toll Brothers be more likely to use process costing or job-order costing? Why? Process costing is utilized when a company produces many units of the same product, making one unit undistinguishable from the next. Because of this identical nature, the same average cost per unit can be assigned. Contrary to this technique, a job-order costing system is used when companies produce many different products or when they are â€Å"made to order†. Because each unit is unique, job costs must be assigned and traced to each specific job in order to determine the total cost of each unit. Based on this information, Toll Brothers would be more likely to use job-order costing. As stated in Toll Brother’s Form 10-K for 2010, â€Å"Each of our single-family detached-home communities offers several home plans, with the opportunity for home buyers to select various exterior styles. We design each community to fit existing land characteristics. We strive to achieve diversity among architectural styles within a community by offering

Miranda v. Arizona Thesis Example | Topics and Well Written Essays - 500 words

Miranda v. Arizona - Thesis Example Though Miranda had not been read his rights, it is believed that his conviction should have remained against him. The enforcement of the reading of a person’s rights was not done until after the case against Miranda. Miranda may have been denied his rights at the time, but this allowed it to be made known that police officers were clearly not doing their job. It brought to light that there needed to be enforcement when reading the rights to criminals to avoid similar situations in the future. As such, Miranda’s case should have been upheld, given the fact that there had been circumstantial evidence and his confession, albeit obtained inappropriately, to still convict him (Allen, 2007). The rights are important to the criminal, but there is still the fact that there was enough evidence present to continue the case. Furthermore, Miranda had already admitted his guilt to the crimes that he was being convicted of. If his rights had been read to him when they should have bee n, and Miranda had exercised his right to an attorney before confessing anything to the police, the case would have gone on in a normal fashion.

Human Genetics Essay Example | Topics and Well Written Essays - 1500 words

Human Genetics - Essay Example This would make both of his parents Dd genetypes. Bob's sister could either not have the disease at all, DD, or be a carrier, Dd. If she was a carrier she then poses the chance of passing the disease on through child birth. Her father was unaffected, which means he must have been DD, which would make his mother probably Dd, so the chances are equal of Bob's sister being either DD, or Dd, with a fifty percent chance of being either of the genotypes. Both DNA and RNA are made up of different tiny particles of information, often referred to as nucleotides. The nucleotides of Adenine, Guanine, Cytosine, and Thymine all make up DNA. In RNA however, Thymine is displaced and Uracil takes its place. It is these four proteins which help make up the coding and information of our bodies. Various proteins can then used these nucleotides, and based on the order they are in, read the information stored there. For example, the order of these nucleotides varies from species to species, and is always different for members of one species to members of another species. The DNA is copied into RNA, which is almost identical to the original coding of the DNA. through the process of transcription the DNA is copied into RNA, which retains almost all of the original information that was held in the DNA. These RNA genes are often composed of both exons and introns. However, only the exons are required for the process of protein synthesis. RNA is then divided into only the parts necessary for coding, the extrons. This leaves us with mRNA. It is then this mRNA that helped guide the process or protein synthesis, or also called translation. The information has all been passed down the chain, leaving mRNA holding all the necessary information for the process and coding for protein synthesis to take place. This process helps shape and build the proteins needed for bodily functions. It is these proteins which help code for different traits and features in humans, be it hair color or eye color, or numerous other traits passed on this way.

If his father had the disease, it is possible he to will develop the disease. If he is tested he would find out weather or not he actually would develop it. Some people would rather not know this kind of information, and would not like to know if they had a disease that would kill them. Other people, would like to know so they would be ready, and also could help them make decisions about having kids. If it turns out he has the disease, he may decided to not have children as to not risk passing it on. It is a hard moral decision, and has positives and negatives on both sides of the argument. If he wants to know that he might die earlier than expected, but hoped to help his children, he may want to get tested. If he wishes not to know however, it may be better he doesn't get

Galactic type Essay Example for Free

Galactic type Essay Galaxies can be explained as massive systems of stars, dust, gas as well as other types of matter that are bound together by gravitational forces to form a single physical mass. As Binney and Merrifield (1998: p 34) explain, on the basis of extensive imaging surveys that have been carried out, it is estimated that there are more than 40 billion galaxies in the universe, that are spread out in a complex large-scale systems for example, clusters, super-clusters. There are also boundaries of huge empty spaces referred to as voids. The sun is just part of galaxy called the Milky Way. This galaxy is a much flattened spiral galaxy that could be comprised by more than 400 billions stars. Through the use of telescopes, it is possible to view these galaxies. Gravitational Lenses Gravitational lenses can be described as galaxies and clusters of galaxies, which are so huge that they cause bends to the route of light objects towards their directions, thus they distort the forms of backdrop galaxies into curves as well as rings. At times these gravitational lenses can even lead to photos of galaxies and quasars to be seen in symmetrical outlines around them. However such cosmetic arrangement is very rare and only occurs in out of a thousand elliptical galaxies. Galaxy merges It has been noted that galaxies comes together to create merges. In such a case galaxies can merge in two different ways. One is through forming stars, and the second way is by merging together. Basing on the present theories of how galaxies are formed, it is expected that they are must be extensive merging going on. In fact, there are many examples to attests this point. However, it is very hard to consistently measure the extent of merging that is happening; it calls for huge samples and keen measuring machines and eyes. (http://www. galaxyzoo. org/science) Understanding these galaxies is a significant part of contemporary astronomy. Galaxies are basic units of matter within the space, and explaining the way they are formed as well as how they have achieved their present form is very critical for various aspects in astronomy. Indeed it is significant to note that what is presently known regarding galaxies started with just a simple classification of how the galaxies appeared through the photos taken using huge observatory telescopes. From these photos, galaxies present a broad diversity of forms, or shapes and can basically be divided into various classes just like living things are classified. Classification of galaxy Visual galaxy classification has continued to be helpful at a moment when galaxies still are not better understood. Classification of galaxies offers an outline for more studies and proposes a sound approach to studying these complex galaxies. Classification of galaxies Binney and Merrifield (1998 pp 36) tells us that, different schemes have been formulated to bring some order to galactic zoo; this has been done through pigeonholing galaxies in relation to one or various properties that include shape, luminosity and spectrum. This section has listed some galaxy classification. Hubble classification The well known and mostly used general scheme of galaxy classification is the Hubble classification. In this classification, galaxies are classified according to how they appear. This system was formulated by Edwin Hubble, and it splits the galaxies into spiral (normal as well as barred), elliptical and irregulars. This scheme is characterized by the well known turning-fork figure. Elliptical galaxies are further grouped from spherical (E0) to highly elongated (E7) in relation to their increasing eccentricity. Generally, spirals vary from Sa (those with arms closely wound) to SBc (those with arms extensively spaced). Irregulars are referred to as Ir. However, Alan Sandage added an extra category to this initial scheme. What was added is S0 for describing lenticular system that has a nucleus that is surrounded by a circle-like structure that does not have spiral arms. Accordingly Buta, Corwin and Odewahn (2002, p, 3) explains that, Galaxies are as well usually termed as ‘early’ for those designated as E and S0 or to be ‘late’ for those designated as Sb, Sb and Irr, in essence this is a remainder of early ideas that galaxies physically evolved alongside the Hubble order. Sadly, this classification is contrary to that of the leading stellar population among these types, and it is also contrary to the early-late classification used in the Yerkes nomenclature. The figure bellow shows some of the galaxy classifications Source: http://www. daviddarling. info/encyclopedia/G/galaxies. html Morgan classification William Morgan also formulated a scheme of classifying galaxies that applies the integrated spectrum of stars and their shapes (apparent and real) together with the degree of the galaxy central concentration. This scheme spells out the galactic spectral form as, a; af; fg; g; gk or k (the letter/s corresponds to the various integrated stellar forms). There are other form used for example, S for spiral; B for barred spiral; E for elliptical structure; L for low surface brightness and N for tiny bright nucleus. Numbers are used to classifying the inclination line of vision, thus, 1 is used for face on while 7 is used for edge-on (numbers 1 to 7 are used). Accordingly, Andromeda Galaxy classification is as kS5 De Vaucouleurs-Sandage classification In this classification, SA designates ordinary spirals, while SB designates barred spirals. Then a lower case s in brackets designates S-shaped spirals. Alternatively r will designate ringed shape. Lastly, various transitional phases have been incorporated between SA spirals and Magellanic irregulars Im. Thus using this classification, Andromeda Galaxy is classified as Sa (s) b. Van den Bergh (DDD) classification This classification comprises two parameters. The first one is galactic type (this are Sa; Sb; Sc and Ir). The second parameter is the luminosity class (designated as I, II, III, IV and V). Just like the MKK structure of stellar luminosity classification, the notations S- as well as S+ are applied to designate sub-giant species that have low or high resolution, correspondingly. S (B) notation has created to designate objects that are intermediate between real spirals and the barred spirals. Conclusion Galaxy classification is very useful since it provides a lot of insight information on physical aspects of galaxies. In classifying galaxies, there are various schemes that are used; however, the scheme formulated by Edwin Hubble though revised over the years still remains the most widely used. Classification of galaxy has laid down the foundation of future study in understanding the galaxies. Through correct classification we gain better understanding of these complex galaxies and indeed of our universe.
