Total drag and its variation with altitude Essay Example

Total drag and its variation with altitude Paper The equation for total drag is: D = CD x S x ? rV2 (Preston, R) where, CD is the coefficient of drag. It must be subdivided into two parts, the Cdi (Coefficient of induced drag) and CDp (Coefficient of parasite drag. ). Therefore it can be written as: D = (Cdi + Cdp) x S x ? rV2 (Preston, R) The airplanes total drag determines the amount of thrust required at a given airspeed. Thrust must equal drag in steady flight. Lift and drag vary directly with the density of the air. As air density increases, lift and drag increase and as air density decreases, lift and drag decrease. Thus, both lift and drag will decrease at higher altitudes. Fig 1 shows the total drag curve which represents drag against velocity of the object. The fuel-flow versus velocity graph for an air graph is derived from this graph, and generally looks as shown in Fig 2 From the above drag it is seen that the total drag is minimum at a certain velocity. This occurs when the parasitic drag is equal to the induced drag. Below this speed induced drag dominates, and above this speed parasite drag dominates. Design engineers are interested in minimizing the total drag. Unfortunately many factors may conflict.

Conversely, a high wing loading (i. e. a small wing) with a small aspect ratio produces the lowest possible parasite drag but unfortunately is the produces for a lot of induced drag. In recent time it is seen that jet airliners have longer wings, to reduce induced drag, and then fly at higher altitudes to reduce the parasite drag. This causes no improvement in aerodynamic efficiency, but the higher altitudes do result in more efficient engine operation. (Preston, R) Angle of Attack (AOA), is the angle between the wing and the relative wind. Everything else being costant, an increase in AOA results in an increase in lift. This increase continues until the stall AOA is reached then the trend reverses itself and an increase in AOA results in decreased lift. The pilot uses the elevators to change the angle of attack until the wings produce the lift necessary for the desired maneuver. Besides AOA other factors also contribute to the production of lift, like relative wind velocity and air density i. e. temperature and altitude. Changing the size or shape of the wing (lowering the flaps) will also change the production of lift. Airspeed is absolutely necessary to produce lift. If there is no airflow past the wing, no air can be diverted downward. At low airspeed, the wing must fly at a high AOA to divert enough air downward to produce adequate lift. As airspeed increases, the wing can fly at lower AOAs to produce the needed lift. This is why airplanes flying relatively slow must be nose high (like an airliner just before landing or just as it takes off) but at high airspeeds fly with the fuselage fairly level. The key is that the wings dont have to divert fast moving air down nearly as much as they do to slow moving air. Air density also contributes to the wings ability to produce lift. This is manifested primarily in an increase in altitude, which decreases air density. As the density decreases, the wing must push a greater volume of air downward by flying faster or push it down harder by increasing the angle of attack. This is why aircraft that fly very high must either go very fast e. g. Mach 3, or must have a very large wing for its weight. This is why the large passenger airplanes cruise at higher altitude to reduce drag, and hence save on the furl costs. (â€Å"Aircraft for Amateurs†, 1999) Small sized aircrafts have lower than normal Reynolds number. The drag coefficient attributable to skin friction is hence higher for the small aircraft. For this reason, the maximum lift-drag ratios characteristic of business jet aircraft tend to be lower than those of the large transports. Hence, the smaller flights can fly at relatively lower altitudes. References Books John A. Roberson Clayton T.

The little zombies first Professor Ramos Blog

The little zombies first For as long as I can remember I have always had a love for scary things and makeup. Around the age of 12 I started to get into special effects makeup like in the horror movies. Making burns, bruises and cuts was a typical Saturday for me. Within the first few months of dabbling in special FX makeup, my mom showed me an ad for the â€Å"IE Zombie Beauty Pageant†. This was basically a beauty pageant but as a zombie,contestants had to be in full zombie makeup and complete the opening, talent, Q and A and evening gown portion of the competition. As soon as she told me about it I started working on my zombies background, how I got infected and just really building up my backstory. Our first meeting was very nerve racking for me, I was so excited then getting incredibly nervous when I saw the people I was competing against. I had only been doing this kinda makeup for not even 5 months and now I was entertaining a contest with grown women (me being the youngest and the second younges t was 21), I thought â€Å" These women have probably been doing makeup for as long as I have been alive, there was no way I could really compete with them†. The fear of my makeup looking like a total amateur made my stomach drop and my heart just stop. â€Å"I really did not think this through† I thought to myself, â€Å"No way was I was going to go through with this†, the embarrassment was too much. I stayed for the rest of the meeting to see what this thing was really about. We had dance routines and costume changes it was so overwhelming and no one even mentioned the makeup not once. Later after going home going over the schedule again and again really contemplating if I was going to do this I saw the first mention of the makeup. I initially just wanted to it for the makeup, thinking we might have workshops or something to do with even the basics of makeup basics but no. Makeup was all self done or if you were lucky enough like the eventual winner and the runner up you knew someone who could do your makeup professionally. I was not so lucky. So after school I would hurry home do my homework then practice some makeup, hurry take it all off then goto rehearsal (which was 3 hours long) then come home around 11 at night then restart everything the next day. It was a month of rehearsal and it was the longest month of my life. For the first time I wanted October to be over. I didn’t feel I made ANY improvement on my makeup and that I would make the biggest fool of myself. I had been YouTubing and recreating the same look over and over again using extremely forei gn materials like liquid latex, molding clay, spearmint glue and even attempting several times to make my own body paint. (I was on an extremely strict budget) I was clueless on the process, just knowing my very basics of colors and trying to remember when I mix this and that it makes it look like this. It was coming down to the last two weeks before the pageant everything was getting real now.   MTv was following around one of the contestants, doing behind the scenes of everything. I knew I was going to be on tv, but the thought of the off chance that my makeup might be sent me through a whirlpool of emotions. They wanted us to help get the word out, wanting us to go downtown with full face of makeup and pass out flyers. This was it I thought, everyone is going to see how tragic my makeup was, I was just going to drop out so I didnt have to embarrass myself more than I was going to tonight. Right after getting   home I started on my makeup. Damn I thought â€Å"I only practiced the same look and I couldnt copy the same look for the pageant:† I was so lost, how many zombie looks could there be? So I quickly googled zombie and the first thing that came up I tried so incredibly hard to recreate on the spot, spending almost 2 hours doing it. Starting then redoing certain cut s or burns, putting a hairdryer to my face trying to make the latex dry without catching it or myself on fire. Finally this was as good as it was going to get. My pale face with blue and green hues all over, ash black burns on my forehead and scar on my neck. I didnt look completely hopeless, wishing that was the case. After being down there for less than five minutes the unimaginable happened, people were approaching me, complimenting me. They actually thought it was good, they liked it. Telling me how disgusting it was and how scary I looked (these were the best complements I could ever ask for) asking who did my makeup and being in total Awe when I told them I did it. Under all that zombie makeup was an extremely happy little girl. Even if they were lying just to make me feel better at that moment I felt something that I hadnt felt in the longest time, confidence. Those total strangers gave me the courage to go through with the pageant. The day of the pageant was the first time we did   an actual dress rehearsal, full makeup and costumes. This is it I thought â€Å"time to make a complete fool of myself†. I felt as though I was jumping into a sea of hungary sharks, ready to be torn apart. We spent the whole day there doing our makeup and rehearsing again and again and again. With all the hot lights and the dancing with our face and body full of makeup we started to wish we were dead. Next thing I know we were just an hour away from opening the doors. I was the most apprehensive about going through with this than I had every been. â€Å"Okay† I said to myself   Ã¢â‚¬Å"this is going to be the third time others have seen your makeup, nothing to be worried about, you didnt come here to win you came here to show off your art†. Just as I began to calm myself down the doors opened and people came flooding in. Now it was just the insecurities of me only having my mom there to support me, I really did nt expect any of my family to come. So off we go one by one we walk up on the stage as dead as we can be doing the opening number and for some reason as soon as we started all my nerves went away. This was not about me or my makeup, now this was about the show we were putting on, making sure I didnt miss my cue and maintaining my dead persona. Even when were were changing for the next category it was like I was on autopilot going through the motions without even thinking about it. After the evening gown portion we took a small intermission to get the winning results. The winner was determined not by a panel of judges but by the audience. You would place a card in the contestants box then they would tally the votes, the more people you brought the higher of a chance that you would win. I honestly did not care on my placement, how far I pushed myself out of my comfort zone and looking back having an amazing time and a story to tell, as cliche as it is, I was the winner in my book. The votes were in, they had people in   S.W.A.T team costumes to â€Å"control the zombies† we all lined up on stage when they called the two finalist. The girl who was being followed around by MTV got runner up and the women whos husband does professional makeup was the winner. I was so happy that I actually went through with this. After the show was over they wanted to interview everyone again. I unfortunately had to leave early so I wasnt able to get a full interview in bu t I was approached by the coordinator of the show. He pulled me aside and told me that because of my age they were not able to award me with my actual placement of runner up. (the prize for the winners was to travel to a convention and get the word out on the pageant, you needed to be 18 or older to go). In that moment I was the most proud of myself that I have ever been. Being publicly placed at third to find out I actually got second place to a women who had gotten her makeup done professionally, beating the other girl who had also gotten professional help and only having my mom there to vote and support me. I was in complete and total awe, I was completely speechless. Constantly wanting to give up because I didnt think I was good enough based on my experience, skill and age and not letting my fears and insecurities to drag me down. I feel that I accomplished a lot and I know for a fact that it was a major stepping stone for who I am now and what I can accomplish in the future.

The islm model-finance Essay Example | Topics and Well Written Essays - 1750 words

The islm model-finance - Essay Example In the article Sir John constructed a diagram and a system of equations that represent the goods market and money market equilibrium conditions. Eventually this IS-LM model has become a famous framework for teaching, policy analysis and econometric modelling for both closed and open economies (Dimand 324). Mishkin points out that Keynes considers the total quantity demanded of an economy’s output (or aggregate output that is equivalent aggregate income) is the sum of four types of spending: (1) Consumer expenditure (C) – the total demand for consumer goods and services; (2) Planned investment spending (I) – the total planned spending by businesses on new physical capital (machines, computers, raw materials, factories, etc.); (3) Government spending (G) – the spending by all levels of government on goods and services (government workers, red tape, aircraft carriers, etc.); (4) Net exports (NX) – the net foreign spending on domestic goods and services, equal to exports minus imports (536). Aggregate demand (Yad), according to Keynes, is: Yad = C + I + G + NX and when the total quantity of output supplied (aggregate output produced) Y equals quantity of output demanded Yad: Y = Yad, so it is possible to say that equilibrium occurs in the economy (Mishki n 537). So, the Keynesian framework enables economists to analyse how aggregate output depends on changes in its constituents: autonomous consumer expenditure, planned investment spending, government spending, net exports and taxes as well. Hicks suggested his interpretation of the Keynesian model, taking into consideration three aggregate markets (money, capital and goods) (156). Hicks asserted that â€Å"in the short period the market of labour as well as price changes do not play a significant â€Å"active† role, so the model can be introduced as follows (Vercelli 4-5): where L is the aggregate demand for money (equal to

Education and Medicines in Saudi Arabia and the United States Research Paper

Education and Medicines in Saudi Arabia and the United States - Research Paper Example In spite of having various similarities, Saudi Arabia and USA are acutely diverse in various fields. In the field of education, the two countries have a completely different outlook in terms of approach towards education, the rate of literacy, religion followed in school (). Other educational differences include the gender roles, grading scales and stages of education (Stevenson). For instance, attendance is mandatory for primary and secondary level students in the USA, whereas attendance is not mandatory in similar levels in Saudi Arabia (Stevenson). Also, while the USA boasts of a literacy rate of almost 99% for both men and women, Saudi Arabia holds a literacy rate of only 84.7% for men and 70.8% for women (Stevenson). Moreover, the two countries differ grossly in terms of religion followed. Although the majority of the US population follows Christianity, the country is home to the followers of various diverse religions as well. However, Saudi Arabia is a country that strictly fol lows Islam and Muslims dominate society. Also, the two countries exhibit totally uncommon lifestyles (â€Å"The Differences†). People have a conservative mindset in terms of women. Here two women are forbidden to go outside together. Moreover, they have to keep their heads covered in public. On the other hand, USA reveals a liberal and democratic mindset in which both the genders can enjoy equal privileges (â€Å"The Differences†). Strangely, the countries, Saudi Arabia and the United States reveal both similarities and dissimilarities.

Four Theoretical Approaches to Metaphysics Essay Example for Free

Four Theoretical Approaches to Metaphysics Essay There are four theoretical approaches to the metaphysics and they include Dualism and the theory that what exists on can do so on two levels the physical or the mental. The next approach is Materialism which theorizes that everything exists on a physical level. Then there is the Idealism approach which states that everything that exists is mental or spiritual. Finally, there is Alternative Views which theorizes that what exists in neither mental nor spiritual but believed that what exists is both, which means that what exists is neutral. In the Materialism theory of metaphysics it is said that everything is made of some kind of structure that are now called atoms. These atoms are governed entirely by physical laws and are thought to make up everything that we know and see. There were and are still many men in the scientific community that feel this way, but the most pronounced one was named Thomas Hobbes. Hobbes implied â€Å"clearly that all things are made of material particles and that all change reduces to motion. † (cite) His theory states that everything is matter in motion to include an individual’s thought process. Hobbes goes into detail about how this process works and called it perception or sense. His way of describing it is the fact that things have different properties and that the properties do not really exist. The properties of an object are based on what we perceive them to be. We perceive a rose to be beautiful, smell nice, and have red pedals. Those properties according to Hobbes are all based on perception and the rose does not actually have any of these traits. â€Å"The things that really are in the world outside us are those motions by which these seemings are caused. † (cite) Hobbes describes perception as motion from the outside effects the motion of the inside of a person. The motion on the outside affected the motion on the inside and leaves a lasting effect after the motion is complete or dispersed then the motion that remains behind on the inside is left as a memory. The motion that is still on the inside is a perception and in turn is the root cause for thinking, imagination, and memory. As humans we describe this reaction by assigning words to these perceptions and Hobbes labeled that as reasoning. The way that people reason is nothing sort of â€Å"adding and subtracting of the consequences of general names. † (cite) The easiest way that this can be explained would be to refer it to a computer. The hard drive is considered as the movement on the inside and the keyboard and mouse as the outside. The hard drive is made up of a disk and magnet and works by taking the disc and spinning is around at a rapid pace. Next the magnet is moved around to encode the data to the hard drive. This whole process is done through movement and if stationary there is nothing that can be done to retrieve or store information. First to store or retrieve information an external source of movement needs to happen. Movement from the outside was represented as a keyboard and mouse. The keyboard and mouse which is movement from the outside affects the hard drive which is the movement from the inside and vice versa. Now that movement has been represented the reasoning of information needs to be considered. Now we understand what movement effect movement means we can now address the fact of reasoning and perception. All of the information that the computer takes in needs to go somewhere and needs to be retrieved again. The computer makes sense of all the data by assigning numbers to all of the data so that it can be retrieved again. This aspect would be considered our perception which is reasoning which as Hobbes stated before is our thinking, memory, and imagination. Now some people would argue that Hobbes theory does not take into accounts decision making and other voluntary actions, but he does go into detail about how that process works. Hobbes addresses the finer points of the decision process by stating that every decision or movement starts of as an â€Å"endeavor† which was caused by perception. He then breaks it down even into two groups consisting of desire and aversion. When the endeavor is toward something then it is considered a desire and when it is away it is considered an aversion. We associate desire and aversion with words like love and hate or good and bad. So according to Hobbes the basic principle of our decision making is like a magnet. Let’s look at the magnet that is in the computer and affects the hard drive. Sometimes data can be corrupted and the information will not take to the hard drive. The process of corrupt data being entered from the outside can be considered as an aversion. Now any information that the system lets in can be considers as desire. If that did not make sense then lets look at a magnet in general. A magnet has a positive and a negative side. Anything that is attracted to the positive side can be considered a desire and anything that is repelled by the negative side can be considered an aversion. In the recent years there has been some advancements in technology that allows us to uncover the mysteries of the universe. Scientists have found matter that is smaller than atoms and they are calling them subatomic particles. It has been discovered that these particles make up every aspect of the universe and are comprised of some type of energy that is connected with everything else. After this discovery a lot of scientists are rattled about their theory and if Materialism is really the right type of metaphysical theory to go with. However, this does not completely rule this theory out it just seems like that needs to some changes or tweaks to the way that we think about Materialism.

Children and young people’s development Institutions Essay

Institutions that effect children and young people’s development: Some institutions that affect a children’s development are: †¢Children in need †¢NSPCC †¢Banardo’s †¢Sure Start †¢Bereavement councillor †¢NSPCC NSPCC stands for The National Society for the Prevention of Cruelty to Children. The NSPCC was designed to protect children from cruelty. Their aim is to end cruelty to children in the UK. They have 4 main principles, there priority is to protect the children who are most at risk, they learn what is best for the children, the create a leverage for change and they also focus on the areas that are going to make the biggest change. The NSPCC’s local services will concentrate on 7 groups of children; these are the ones that they think are most at risk. These are the children that have experienced neglect before; they are the children that have a high risk of being exposed to physical abuse (these families are the ones that have violet adults, drug and alcohol abuse and mental health issues.) Another group is children that have experienced sexual abuse, children under the age of one, disabled children, children that are black and that come from minority ethnic communities, and look ed after children. The NSPCC affect the children in variety of different ways, they make sure the children are safe and looked after. They could affect the children in a major way because it could be the difference of the being looked after or being neglected. It could also be the difference of the child being having a safe and secure future, the future that every child deserves. †¢Sure start Sure start is government led and its aims are to give the children in the UK the best possible start. It focuses on Early Years Care, Family Care and Education. They promote high quality childcare to children aged 0-12 and  their families. They are a helping hand to the professionals, families and parents of children. This institution can affect a child’s development because there aim is to protect the children; they ensure that they children are looked after. This means the children that they help get the best care, which can affect their emotional and other types of development. Agencies Some agencies that can affect a child’s development are: †¢Council †¢PCSO †¢Children centre †¢Youth officer †¢SENCO †¢Welfare officer †¢Children centre Children centres offer the chance for children to take part in activities outside of school, they also offer children the chance to meet new people and make new friends. They get children off of the streets and give them somewhere safe to play, chill and be away from home. These children centres can have a major affect on a child’s because they allow children to affect the development areas. Emotional because it can make them happy, social because it gives them the chance to meet new people and make new friends, intellectual because they can play logical and thinking games, and physical because they can play sports. †¢SENCO SENCO stands for Special Educational Needs Co-ordinator. They are responsible for day to day operation of the settings policies. The SENCO will co-ordinate additional support for the children that need it, they will liaise with the parents, teachers and the professional that are involved with them. The SENCO’s job is to get in contact with outside services to come in and help the children they think may need it. The SENCO helps the child’s development by requesting additional help for the children that they think need it. Services Services that affect a child’s development: †¢Health visitor †¢Doctors †¢Social worker †¢MAISY – Multi Agency Integrated Services for Early Years Physio therapist Paediatrician Speech therapist All intervention people †¢Health professionals †¢Health Visitors A health visitor’s job is to support new parents and preschool children with assessing the children’s health ensuring that they are healthy. And helping the parents give the right quality of care to the children. They also development appropriate programmes to help give the child the best possible start in life. They offer parents advice on all subjects, and they also look and asses the child’s physical development and do development checks on those children. The health visitor can effect a child’s development because if anything is wrong with the child, they may be the first people to spot it, and give the children the best possible start, so that if doesn’t affect them as much later on in life. †¢Health professional Health professionals are people such as doctors, GP’s, nurses and so on. They are the people we turn to when we are ill, or need assistance. These health professionals can effect a child’s development in many ways, by assessing the children and giving them the right medicine to make them feel better. If a child becomes seriously ill, doctors are the people that know what to do to ensure that they get the right treatment so the illness does persist and become worse. A health professional can affect a child’s development in every way possible, because if they get something wrong then the child come suffer in every area of development.

The Symbolism and Narration of Amy Tan’s “Two Kinds”

Amy Tan demonstrates a child’s struggle for identity in her story â€Å"Two Kinds†. This essay analyses the writing techniques Tan uses in order to express the struggle between parent and child; in which the child is struggling to have her own identity. Typical in Asian cultures, Tan describes the parents’ desire for a child prodigy through strict discipline and expected child obedience. Living in America exposes Jing-mei to American influence. Jing-mei’s mother however spent the majority of her life in China, and expects her child to behave as she would had she been raised in China. This essay depicts American cultural influence as one way to explain Jing-mei and her mother’s contrasting views; the main idea of this essay however is to demonstrate Tan’s use of symbolism and narration to depict the traditional struggle between parent and child. Amy Tan uses the main character, Jing-mei to represent the typical American pre-teen who is determined to break free from her mother’s uncontrollable need to make her a prodigy. Jing-mei is a rounded main character which the reader is able to watch grow emotionally throughout the story; her need to be herself and defend her position is an important theme throughout â€Å"Two Kinds†. Tan uses the first person narration to draw the reader in personally to JIng-mei and what she is experiencing. The reader can hear Jing-mei’s thoughts and disappointments. The minor character, Jing-mei’s mother, is a flat character in comparison to her daughter. The reader is unable to really know what the mother is thinking because of Tan’s use of second person narration. To help the reader understand the mother’s actions, Tan describes the mother’s history briefly discussed within the first page of the story. Using an important writing technique, Tan gives the reader a look into the mother’s painful history; enough for the reader to understand the mother’s motives as they watch her drill her daughter on popular American trivia facts and not stopping even after Jeing-mei protests. The opening line of â€Å"Two Kinds† is especially important to understanding the mother’s motives. Jing-mei, the narrator tells the audience, â€Å"my mother believed you could be anything you wanted to be in America† (468). This sentence describes the hopes and dreams of Jing-mei’s mother. Tan goes on to explain the mother’s perception of America; she believes America is the answer to all their problems. The readers are not told what happened to her remaining family in China, but it resulted in death and that is enough for the reader to sympathize with the mother and her controlling behavior. The narrator, JIng-mei, gives the audience an understanding of the mother’s motives; this understanding is important in order for Tan to communicate her message of a daughter-mother relationship. The reader has the advantage of knowing the mother’s reasoning for pushing Jing-mei to be the best; Jing-mei however, does not. By using first person narration, the reader experiences Jing-mei’s frustration at being made to perform against her will. In the beginning of â€Å"Two Kinds† however, Jing-mei is excited at the prospect of being famous. Jing-mei thinks, â€Å"in all of my imaginings, I was filled with a sense that I would soon be perfect;† the reader almost feels sorry for the little girl; for many adults can sympathize. Many people can remember a time of innocence when they thought they could do anything, that they could be the perfect child their parents imagined them to be. This need to fill a parent’s high expectations is cause for harsh disappointment as Jing-mei discovers. After witnessing her mother’s disappointment; anger begins to burn inside Jing-mei at having to perform ridiculous tests. This rage turns to an inner protest; Tan portrays this rebellion as Jing-mei’s disinterest in test questions. Even after her mother goes through trouble of trading house cleaning for piano lessons, Jing-mei puts in minimal effort. This child rebellion is common in American children; rather than risking being a disappointment, Jing-mei protects her feelings by acting as if she doesn’t care. Tan writes of Jing-mei’s private protest, â€Å"so now on nights when my mother presented her tests, I performed listlessly, my head propped on one arm. I pretended to be bored. And I was† (470). Jing-mei became her own prodigy. The story’s title, â€Å"Two Kinds†, is a description of the theme of the story. The title of Tan’s story is a symbol of the two generations and two cultures depicted in â€Å"Two Kinds†. The mother is from China, with Chinese traditions and Jing-mei was raised in America, influenced by America’s culture; where children had more say and questioned their parents’ judgments as Jing-mei finally did when she accused her mother of wanting her to be a genius. There is a distinct gap between mother and daughter as seen in both generational and cultural differences. The most important use of symbolism in â€Å"Two Kinds† is the piano. The piano becomes the link between Jing-mei and her mother; although this is not clear to Jing-mei during childhood. Jing-mei is angered by being forced to play the piano and purposely doesn’t take it serious; much like the way Jing-mei does not take her mothers dreams for a prodigy serious. Underlying the rebellion Jing-mei demonstrates during her piano lessons; she finds the chance to play in a talent show exiting; her excitement reveals that small part of her that still wants to please her mother and be the little prodigy her mother hopes for. Jing-mei describes her childish excitement to make her mother proud, she says, â€Å"When my turn came, I was very confident. I remember my childish excitement. It was as if I knew, without a doubt, that the prodigy side of me really did exist† (474). Tan accurately portrays a child’s inner desire to please her parent, as she writes of Jing-mei’s sudden excitement. All Jing-mei’s protests were forgotten and she had a chance to make her mom proud. Tan’s narrative style allows the reader to see the full extent of Jing-mei’s emotional growth. The narrator is Jing-mei as an adult, looking back at this specific time of her childhood in refection. It isn’t until she is an adult that she can appreciate what her mother was trying to accomplish during her childhood. The narrator realized that everything changed after the disastrous recital. Her mother’s dreams seemed to fade after JIng-mei demonstrated what she had learned throughout her lessons. Tan showed a mother’s unconditional love for her child by the mother insisting that Jing-mei continue her lessons even after the recital fiasco. While it may seem that the mother was extremely controlling, making the child continue with lessons she did not want; the reader can interpret this as a mother who does not give up on her child; a mother who is determined to show her child that she can accomplish anything she puts her mind to. The piano remains a symbol for the relationship between Jing-mei and her mother. After things escalate and Jing-mei speaks out against her mother, wishing she weren’t her daughter, the piano remains unused. Tan uses this opportunity to fast forward to all the future disappointments she causes her mother.   The piano continues to be a link between mother and daughter when the mother asks Jing-mei to take it on her thirtieth birthday; and encourages her to try it again by complimenting on her quick learning ability. This opened the door to a new understanding in their relationship. All of a sudden the piano became a symbol of Jing-mei’s acceptance by her mother and herself. Jing-mei as an adult appreciates what her mother had done for her as a child. The fondness she suddenly has for the piano that brought her such frustration and embarrassment symbolizes the acceptance of herself and of the truth behind her mother’s pushy but well meaning behavior. The piano symbolizes the mother-daughter bond which is tested during childhood but strengthens in time with understanding. In conclusion, Tan uses first person narration to give the reader a more intimate experience with the characters. The symbolism used in â€Å"Two Kinds† portrays the classic struggle between mother and daughter; a daughter seeking her own identity and a mother wanting the best for her daughter. â€Å"Two Kinds† addresses the pain that family can bring upon one another but also the forgiveness and understanding that can be reached between loved ones.         

These 5 Microsoft Word tweaks that will make your resume shine

These 5 Microsoft Word tweaks that will make your resume shine A good resume is your foot in the door at the best companies. Even if you have a solid background filled with relevant jobs that make you an ideal candidate, you still need your resume’s formatting to sing. Your number one goal is to make it easier and faster for recruiters to read (and fall in love with) your resume. Remember, you likely have only a quick glance of a few seconds to make a first impression- anything sloppy, out of place, or distracting might send you right into the reject pile before a recruiter has even read one word. Read on for the basic checklist you should use to make sure everything is clean and professional in MS Word before you attach and send away.1. Show/Hide formatting and fix sloppiness.Utilize the Show/Hide feature to see if everything is laid out neatly by clicking the button that looks like a backwards â€Å"P† on your Home toolbar or clicking Ctrl+8 or command+8. Now, you can see all the paragraphs you’ve made and your use of spac ebar vs. tabs. Using the now-visible marks, standardize all spaces and delete any that don’t belong. This is your chance to clean up all the messy bits of DIY formatting you did that might not translate well across computers.At this point, align all of your content uniformly. Use the tab stop menu in the top left corner of your document, just to the left of the ruler. Click until you see the tab stop you want, then click the ruler where you want that stop to be. Use bullets for consistent (and easier to adjust) spacing when you’re listing experiences or skills, and use the Line and Paragraph Spacing tool to manage the size of spaces in-between sections, sentences, bullets, and paragraphs.2. Insert a header and footer.Use the header and footer feature to make use of all the precious space you have. You don’t have a lot of space to work with on one page, so you want to use the body of your resume to list skills, work history, and education. Don’t waste this space with contact information- put that at the top and bottom. Just use the â€Å"Insert† tab drop menu to find the kind of header/footer formatting you want, then go nuts.3. Go bold and use bullets.Bold job titles to make them pop. Then, use bolded headers to delineate your sections, and under them, use bullets to list your skills and relevant bits of detail. Formatting your resume like this makes it easy to follow, clean, and organized. Keep your bullet style neat and simple- in most cases, a resume is not the time for creativity.4. Prioritize.Put your best and most relevant experience and skills at the top, moving all the rest (especially if it’s basically filler) to lower sections. The recruiter’s eye reads the top few lines first (and sometimes stops there!). Make sure your best stuff is most easy to find.5. Convert to PDF.To ensure security and to make sure your beautiful formatting work doesn’t get jumbled up on someone’s not-updated machi ne, make sure to click â€Å"Save as† and then convert your final resume into a PDF. A quick double check will show that this new uneditable document is ready to be uniformly read by any recruiters- just as you wanted them to see it.

An overview of scrum methodology

An overview of scrum methodology Software development organizations have become more interested in agile methodologies, whose focus is client collaboration, individual value, and adaptation to change. Scrum is a framework within which people can address complex adaptive problems, while productively and creatively delivering products of the highest possible value. Scrum makes clear the relative efficacy of your product management and development practices so that you can improve. The Scrum framework consists of Scrum Teams and their associated roles, events, artifacts, and rules. Each component within the framework serves a specific purpose and is essential to Scrum’s success and usage. What is the scrum? Scrum is a framework for managing work with an emphasis on software development. It is designed for teams of three to nine developers who break their work into actions that can be completed within time-boxed iterations, called sprints (typically two-weeks) and track progress and re-plan in 15-minute stand-up meetings called daily scrums. Approaches to coordinating the work of multiple scrum teams in larger organizations include Large-Scale Scrum, Scaled Agile Framework (SAFe) and Scrum of Scrums, among others. Scrum values:- Scrum is a feedback-driven empirical approach which is, like all empirical process control, underpinned by the three pillars of transparency, inspection, and adaptation. All work within the Scrum framework should be visible to those responsible for the outcome: the process, the workflow, progress, etc. In order to make these things visible, scrum teams need to frequently inspect the product being developed and how well the team is working. With frequent inspection, the team can spot when their work deviates outside of acceptable limits and adapt their process or the product under development.[18] These three pillars require trust and openness in the team, which the following five values of Scrum enable:[14] Commitment: Team members individually commit to achieving their team goals, each and every sprint. Courage: Team members know they have the courage to work through conflict and challenges together so that they can do the right thing. Focus: Team members focus exclusively on their team goals and the sprint backlog; there should be no work done other than through their backlog. Openness: Team members and their stakeholders agree to be transparent about their work and any challenges they face. Respect: Team members respect each other to be technically capable and to work with good intent. Scrum roles:- The three roles defined in scrum are the ScrumMaster,the product owner, and the Team (which consists of Team members). The people who fulfill these roles work together closely, on a daily basis, to ensure the smooth flow of information and the quick resolution of issues. ScrumMaster The ScrumMaster (sometimes written â€Å"Scrum Master,† although the official term has no space after â€Å"Scrum†) is the keeper of the process. The ScrumMaster is responsible for making the process run smoothly, for removing obstacles that impact productivity, and for organizing and facilitating the critical meetings. The ScrumMasters responsibilities include Removing the barriers between the Development Team and the Product Owner so that the Product Owner directly drives development. Teach the Product Owner how to maximize return on investment (ROI), and meet his/her objectives through Scrum. Improve the lives of the development Team by facilitating creativity and empowerment. Improve the productivity of the development Team in any way possible. Improve the engineering practices and tools so that each increment of functionality is potentially shippable. Keep information about the Team’s progress up to date and visible to all parties. In practical terms, the ScrumMaster needs to understand Scrum well enough to train and mentor the other roles and educate and assist other stakeholders who are involved in the process. The ScrumMaster should maintain a constant awareness of the status of the project (its progress to date) relative to the expected progress, investigate and facilitate resolution of any roadblocks that hold back progress, and generally be flexible enough to identify and deal with any issues that arise, in any way that is required. The ScrumMaster must protect the Team from disturbance from other people by acting as the interface between the two. The ScrumMaster does not assign tasks to Team members, a task assignment is a Team responsibility. The ScrumMaster’s general approach towards the Team is to encourage and facilitate their decision-making and problem-solving capabilities so that they can work with increasing efficiency and the decreasing need for supervision. The goal is to have a team tha t is not only empowered to make important decisions but does so well and routinely. Product Owner The Product Owner is the keeper of the requirements. The Product Owner provides the â€Å"single source of truth† for the Team regarding requirements and their planned order of implementation. In practice, the Product Owner is the interface between the business, the customers, and their product related needs on one side, and the Team on the other. The Product Owner buffers the Team from the feature and bug-fix requests that come from many sources and is the single point of contact for all questions about product requirements. Product Owner works closely with the team to define the user-facing and technical requirements, to document the requirements as needed, and to determine the order of their implementation. Product Owner maintains the Product Backlog (which is the repository for all of this information), keeping it up to date and at the level of detail and quality, the Team requires. The Product Owner also sets the schedule for releasing completed work to customers and make s the final call as to whether implementations have the features and quality required for release. Team The Team is a self-organizing and cross-functional group of people who do the hands-on work of developing and testing the product. Since the Team is responsible for producing the product, it must also have the authority to make decisions about how to perform the work. The Team is therefore self-organizing: Team members decide how to break work into tasks, and how to allocate tasks to individuals, throughout the Sprint. The Team size should be kept in the range from five to nine people, if possible. (A larger number make communication difficult, while a smaller number leads to low productivity and fragility.) Note: A very similar term, â€Å"Scrum Team,† refers to the Team plus the ScrumMaster and Product Owner. Scrum pros:- Scrum can help teams complete project deliverables quickly and efficiently: Scrum ensures effective use of time and money Large projects are divided into easily manageable sprints Developments are coded and tested during the sprint review Works well for fast-moving development projects The team gets clear visibility through scrum meetings Scrum, being agile, adopts feedback from customers and stakeholders Short sprints enable changes based on feedback a lot more easily The individual effort of each team member is visible during daily scrum meetings Scrum cons:-Nothing is perfect, and the Scrum methodology is no exception. In some cases, Scrum is combined with other project management techniques that can help resolve some of these drawbacks: Scrum often leads to scope creep, due to the lack of a definite end-date The chances of project failure are high if individuals arent very committed or cooperative Adopting the Scrum framework in large teams is challenging The framework can be successful only with experienced team members Daily meetings sometimes frustrate team members If any team member leaves in the middle of a project, it can have a huge negative impact on the project Quality is hard to implement until the team goes through the aggressive testing process Scrum process:- Needless to say, proper planning and smart decision making can help you get past these disadvantages with the Scrum methodology. For example, in larger teams, each member needs to have defined roles and responsibilities with definite goals, so that there is no compromise on quality and no excuse for failure. This will keep the team focused to project goals. Plus, the ScrumMaster needs to guide the team effectively to avoid pitfalls and ensure 100% project success.

Marketing Decicion Making Essay Example | Topics and Well Written Essays - 2000 words

Marketing Decicion Making - Essay Example Effective market communication requires an integrated promotional system that reaches from primary producer to ultimate consumer. Communications flow to markets through long, complex channels that include manufacturers, retailers, wholesalers, consumers, agencies, and media. Each unit can break the chain or pass on the information as it sees fit. The amount and quality of information, therefore, depends on the channel. IMC's most fundamental and perhaps most challenging task is trying to reach people who can conceivably purchase a client's product. Allin (2009). explains marketing communications as "the process by which the marketer develops and presents an appropriate set of communications stimuli to a defined target audience with the intention of eliciting a desired set of responses" (p.37). Formal channels, however, do not account for all marketing communications. Publicity, which is an integral part of many promotional campaigns and sometimes precedes the advertising and sales effort, lies outside them. Although it can be important in gaining market acceptance for products and companies, publicity, like word of mouth, is often a relatively low-grade communications channel with a high degree of interference, distortion, and noise. Marketing communications serve four basic management purposes. ... Third, they help adjust the system to customer and consumer requirements. Fourth, they adjust and help in adjusting the product to customer needs. The task of marketing communications is to get people or markets to progress from a state of unawareness, or even negative reaction, to one of positive action. The stages in this progression are unawareness, awareness, comprehension, conviction, and action (Steve 2009). The theory of information is one that holds promise for the measurement of marketing communications. To date, its primary application is in electrical engineering. It deals with measuring the information content of a message, self-information, bits of information, entropy, the value of average information, loose channels, and noisy and noiseless channels. It provides operational definitions, measures, and a different basis for thinking about marketing communications. The idea of measuring the information content of stimuli, though particularly relevant, is not yet tractable, and the application of this part communications theory to practical marketing situations remains unattained. The careful financial review now being given to investments in plant and equipment or to inventory purchases is destined to be extended to advertising expenditures. Advertising messages are meeting increasing competition from a plethora of other ads, from other media, from competitors, and from all the act ivities that vie for a person's attention. As output swells and communications facilities increase, more claims will be made on consumer time and the cost of marketing communications will skyrocket (Ng and Houston 2009). Pros and cons: advertising. The advantage of advertising is
