Porter Essays - Critical Thinking, Narratology, Rhetoric, Proverb
Watchman I: Organizational Pattern: Rogerian Christa Porter inspects what a genuine companion is. She does this by setting up an introduction with a Rogerian design as it's premise. This example is found in a few perspectives referenced by Porter, the more evident angle is the point at which she welcomes the crowd to offer their input of what a genuine companion is. Doorman is essentially finding what the audience's positions are when asking what they think a genuine companion is. Doorman additionally uncovers her example decision when she presents her own thoughts, essentially bolstered by pertinent Bible sacred texts. II: Elaborative Devices: Q and A, Rhetorical Questions, Religion, Definition (operational), Discussion, Proverbs Christa Porter built up her contention and introduction completely by including a large number of elaboration gadgets. At first, Porter feels including a short conversation of what the audience members definitely know, what a companion is, would be exceptionally emotional. Non-serious inquiries assume a job in Porter's improvement of her introduction, she asks the crowd a few of these inquiries identifying with what they would do, think and know. Definitions can be valuable, particularly when you are attempting to welcome the audience members to uncover what they think the significance of something is. Watchman utilizes an operational definition to achieve the errand of characterizing what a genuine companion is and does Finally, Porter exploits the viability of the utilization of Proverbs and religion by utilizing a few sections from Proverbs as help for her contention. III: Interactional Goal: To Articulate a Perspective One of the simpler components to bring up is Porter's interactional objective, which happens to express a point of view. To see this interactional objective at work basically make a stride back and take a gander at how she builds up her introduction. Doorman shares data about what a genuine companion is and afterward presents her perspective about kinship. She moreover urges others to get associated with the introduction and conversation. IV: Conclusion Watchman's decision is short yet to some degree powerful. I review when you referenced in class that the decision ought to really be somewhat longer than those referenced in our course readings. Watchman sets up her decision by giving a circumstance that shows the components of a genuine kinship. The end is cultivated when she thoroughly analyzes the given circumstance with a speculative kinship with God. V: Commitment Statement: This component is one of the simpler pieces to disect from the introduction, for the most part as a result of it's structure. Watchman takes what you called ?the path of least resistance?, by utilizing the state, ?today we are going to discuss something?. Fundamentally Porter's duty articulation is, she needs to discuss a recognizable point (fellowship) while accepting new thoughts from the audience members. VI: Opening and Closing: I spared this investigation for last, since I feel she invested minimal measure of energy building up these components inside her introduction. Above all else her initial comprises of just ?Good Morning Y'all?, conceded it is a Sunday School class, it still, I feel, requires an increasingly elaborative style. For instance, she could have stated, ?Good Morning Everyone, God is acceptable and qualified to be lauded, and so on. Something like that would have been progressively fitting. VII: Compare and Contrast: Doorman settled on some shrewd decisions just as awful decisions. Despite the fact that the setting and crowd are moderately impartial, on the grounds that they all know one another, I feel Porter's opening would have been progressively compelling if slang and popular word decisions had not been utilized. To the extent awful decisions or components, Porter did exclude any such further angles inside her introduction. Then again, Porter's savvy decisions were made when she utilized that little conversation toward the start of the introduction. This conversation tempted the audience members to review data about practical pertinent happenings in their lives. Such an inciting is what is important to the influential idea of Sunday School. Another shrewd decision is when Porter decided to incorporate a clarification of what a genuine companion is and how that companion may act in a given circumstance. This was powerful primarially on the grounds that it permitted the audience members to set up a feeling of sentimentality inside over a wide span of time kinships. VIII: Lastly, Porter's end is to some degree implanted inside her decision. She notice's that the purpose of her introduction is confiding in God, however doesn't include any farewells, expressions of gratitude or if nothing else

Cross of Gold Essays
Cross of Gold Essays Cross of Gold Essay Cross of Gold Essay In 1896. three mature ages after the Panic of 1893 . a grown-up male by the name of William Jennings Bryan conveyed one of the most chronicled addresss to this twenty-four hours. In the late 1800ââ¬â¢s a populist movement was go oning and individuals were get bringing down to pay heed. Political corruptness and enormous concern designs hurt non just workers. yet, other than husbandmans. At the point when husbandmans sorted out into confederations. lastly into the Populist Party. they represented a test to the ruling bipartisan framework. During the 1896 decisions the Populist Party had started to turn and determine drive. they had placed a congressperson in office and assumed control over the Kansas area Legislature. The appointment of 1896 was known as the clash of the measures since it concentrated mainly on the gold versus Ag models of cash. People groups needed quick answers for the monetary emergency and the help of free Ag mintage started to lift in 1894. During the Democratic Convention William Jennings Bryan conveyed the Cross of Gold location. This location is viewed as one to the most great known political addresss. This location when evaluated with the recorded setting and Bryanââ¬â¢s political purpose of position makes an extraordinary depiction of what our state was going through in the ahead of schedule to mid 1890ââ¬â¢s and the significance and noteworthiness of the 1986 presidential political decision. In 1894. 20 Democratic territory stages required a free mintage of silver in spite of President Clevelandââ¬â¢s opposition. Force from the gathering moved toward the South and its mindset mirrored the places of Southerners and Democrats turned into a sectional gathering. not, at this point a national gathering. As an outcome this left the Democrats without a pioneer and this is the place Bryan got included. The republicans had vanquished their Ag stage and needed the plated basis. Bryan needed to take the Ag Democrats and felt that he could. He conveyed the Cross of Gold location and won the presidential selection the accompanying twenty-four hours. This location should get the gift from the Democratic Party and to procure Bryan into the Presidential political race. He was fruitful at both of these. William jennings bryans boss proclamation in his location is that the overlaid model will non help the state as it battles with joblessness and high association rates and everything else the Panic of 1893 made. The state expected to secure out of this trench and expected to make it now. He accepted that Ag mintage was the way to bring through this. At the point when Bryan says Having behind us the bring forthing large numbers of this state and the universe. upheld by the business associations. the working inclusions. what's more, the toilers everyplace. we will answer their interest for a plated model by expressing to them: You will non push downward on the temple of work this Crown of aggravations. you will non execute world upon a cross of gold. . he mentions that by tolerating the plated measure they would be murdering the state. What's more, that the overlaid standard would non pass on the state out of the downturn they were in. It would do the state come up short. Another voyaging quote in this location is You come to us and state us that the incredible metropoliss are supportive of the overlaid standard ; we answer that the extraordinary metropoliss rest upon our wide and fruitful grasslands. Torch your metropoliss and go forward our homesteads. what's more, your metropoliss will bounce up again as though by magic ; yet destruct our homesteads and the grass will turn in the roads of each city in the state. This shows yes the incredible metropoliss are agreeable to the plated measure yet they donââ¬â¢t comprehend what the rest of the state is going through. They are reliant on the homesteads and agribusiness of the U. S. also, if the metropoliss bomb they can reproduce them and fix them. in any case, if the homesteads come up short there is nil that can fix this. The husbandmans are in urgent requests of help and the plated basis is non the arrangement. free Ag is. In this location he other than says Ah. my companions. we state non single word against the individuals who live upon the Atlantic coastline. yet, the robust pioneers who have conquered all the threats of the wild. who have made the desert to sprout as the rose-the trailblazers off out at that place [ demonstrating toward the West ] . who back their children close to Natureââ¬â¢s chest. where they can blend their voices in with the voices of the fowls out there where they have raised school buildings for the guidance of their juvenile. houses of worship where they acclaim their Godhead. also, memorial parks where rest the remains of their dead-these individuals. we state. are as meriting the thought of our gathering as any individuals in this state. It is for these that we talk. We do non come as assailants. Our war is non a war of vanquishing ; we are fighting in the resistance of our places. our family units. what's more, relatives. We have appealed. what's more, our solicitations have been despised ; we have begged. what's more, our supplications have been ignored ; we have asked. what's more, they have ridiculed when our disaster came. We ask no longer ; we beseech no more ; we request no more. We challenge them. . . . This quote has incredible criticalness in the way that he discusses how he is non expressing anything awful about the individuals populating on the east beach. who despite everything seek England for contemplations and convictions (, for example, the overlaid model ) . He discusses the trend-setters and all they have achieved. what's more, why they have the right to hold a state in the political universe simply every piece much as the rest of the state. He is looking to voice every one of their thoughts and positions in this location. Bryan fights for the individuals who are battling to populate and back up their family units and spots. He says that they should not beg anymore or request yet rather withstand what they ( Republicans ) are trying to make. Bryan in this way lost the presidential political decision to William McKinley. however, the location that he gave had more prominent hugeness than simply procuring the Democratic assignment for presidential term. This made a dilemma for the democrats since they did non accept any gathering would back free Ag. so now they were confronted with an intense pick. set up their ain campaigner or side with Bryan. Bryan fundamentally split up the Populist Party since half of them figured they should agree with the Democrats ( Bryan ) . be that as it may, the other half were idealists and needed to make everything without anyone else. he did non win the political race yet he halted the outsider and changed the way the Democratic Party thinks. Without request. William Jennings Bryanââ¬â¢s Cross of Gold location was one of the greater part of import and significant location in all of political relations. It changed the goals of the Democratic Party and kept up the conventional bipartisan framework. Without the Acts of the Apostless of Bryan would this state even be above water still? This location is truly one of the best addresss I have ever heard/read is extremely significant as our state is in another enormous downturn and makes you look previously and perceive how we have continued on and vanquished occupations before and gives trust we will improve of this downturn.
Discuss Changing Family Structures in the Uk and Give Examples of Sociological Theories That Provide Explanations as to Why and How Families Have Changed.
Talk about changing family structures in the UK and give instances of sociological hypotheses that give clarifications with respect to why and how families have changed. This paper will talk about the different family structures in the public arena. It will give hypothetical clarification regarding why and how families have changed. The paper will likewise bring factual, verifiable and political proof to back up the purpose behind these changes. During the pre-modern culture the ââ¬Ëextended familyââ¬â¢ was the most widely recognized family structure.This family structure includes three ages including the guardians, youngsters and either the grandparents (vertical-broadened) or uncles and aunties (on a level plane expanded). The more distant family structure was fundamental for this general public as families were a ââ¬Ëunit of productionââ¬â¢ so they required the same number of laborers as they could get. Michael Anderson (1971) contended that in ââ¬Ëcritical life sit uationsââ¬â¢ there was a reliance on the more distant family for help and backing. At that point Parsons (1949) said enormous families were financially valuable, so the more distant family was the most fit structure.However, during in the modern insurgency family life changed. It was no longer observed as a ââ¬Ëunit of productionââ¬â¢ yet now a ââ¬Ëunit of consumptionââ¬â¢. The ââ¬Ënuclear familyââ¬â¢ rose and turned into the principle family structure. Be that as it may, the more distant family may become famous again as in our present society individuals are living longer and state financing on private consideration has diminished so this has moved the consideration and duty onto the family. Additionally, there has been an expansion in Multi-generational families. ââ¬ËThe prior time of youngster bearing decreasing the age hole between generationsââ¬â¢ (Fulcher and Scott, 2011: 446)The ââ¬Ënuclear familyââ¬â¢ comprised of two ages, the mother, fathe r and their kids. Parsons (1949) contended that industrialisation brought about a move from the more distant family to the family unit, as its attributes are progressively run of the mill for an entrepreneur society. Parsons (1956) accepted that you should move where there is work and that you should just take your close family with you not every person. This is the reason family units were progressively valuable as it was simpler to move for work with simply your quick amily. With the mechanical unrest and the development of private enterprise, creation was not, at this point completed by relatives, yet by laborers. Open arrangements were set up during 1940-1970, for example, the government assistance state, which was intended to help family jobs (provider and caring mother). From that point forward there has been noteworthy changes in open strategies, for example, the separation change act (1967), the premature birth act (1967), the equivalent compensation act (1970), the sex segr egation act (1975) and maternity leave was introduced.This gave ladies more opportunity and more open doors particularly inside business and way of life decisions. This lead to social change; delay of marriage and childbearing, the quantity of separations in England and Wales expanded from 6,000 of every 1938 to more than 48,000 out of 1968, and in 1960 the ripeness rate was 2. 72%, dropping to 1. 93% in 1998. Because of these fast increments in separate from living together has gotten progressively ideal for couples as there are no legitimate ties, the couple can perceive how it goes before settling on any significant choices, for example, marriage.Also couples may wed later as weddings are costly and they donââ¬â¢t have the cash to bear the cost of one because of the downturn, anyway living with one another sets aside cash. This was the equitable and instructive upset and the period of the family unit. Be that as it may, with new strategies set up and such significant social ch ange, from the 1970s onwards it turned into the ââ¬Ëpost-mechanical societyââ¬â¢ and the ascent of post-innovation. This general public brought new family structures, and units that were recently seen as unsatisfactory became acceptable.Since the separation change act (1967) divorces have quickly expanded bringing about numerous re-relationships, presenting the reconstituted nuclear family. This family incorporates kids that live with one organic parent and a stage parent. These families may likewise incorporate advance/relatives and sisters. Separation has additionally implied there are a lot increasingly single-parent families. This is a family structure where just one parent deals with the youngsters. This can be because of birth outside of marriage, separation and demise or detainment of a partner.Murray (1990) would contend that the ascent in single parent families is because of the underclass and illegitimate families. Young men without fathers are insufficiently mingled and donââ¬â¢t have a male good example. At the point when they have their own kids they wont have a comprehension of a ââ¬Ëdadââ¬â¢ job, so this may bring about them being missing in the childââ¬â¢s life and partition from the spouse/accomplice. Marx (1848) would contend that the breakdown of marriage is because of the contention that the entrepreneur society is making and this is influencing relationships.Feminist, Delphy (1977) contends that the abuse of womenââ¬â¢s work is established in ââ¬Ëthe local method of productionââ¬â¢ inside the family unit, not in the industrialist method of creation. ââ¬ËMen hold a predominant situation inside the residential method of creation and endeavor ladies through marriageââ¬â¢ (Fulcher and Scott, 2011: 435). This misuse could make strife and abusive behavior at home may happen bringing about partition/separate. In conclusion, a few people accuse single-parent families for the leniency of the sexual revolution.Jeffre y Weeks (1989) accepts that post-war changes in free enterprise has prompted another delight looking for demeanor in females, which brought about sexual conduct as a wellspring of joy rather a methods for delivering youngsters. This can identify with why there are such a large number of single-parent families headed by ladies from births outside marriage. At last the latest kind of family structure is ââ¬Ësame sex familiesââ¬â¢. This includes a gay couple (gay or lesbian) that deal with kids. This is the freshest nuclear family as the common association law was just passed in 2004.Since then 45,000 have been shaped up until 2010. Gay couples have been obvious for quite a while anyway as of late have the perspectives towards them become increasingly satisfactory bringing about the common association law. Beck (1992) says this is a direct result of individualisation; individuals are structuring their lives dependent on their own decision not desires. Likewise, individuals have t otally different perspectives presently to already ever, so homosexuality is all the more broadly acknowledged. Taking everything into account, family structures are continually changing and there will never be just one type.Family structures will in general base around fitting the kind of society there in. Arrangements can increment or abatement certain family structures. For instance the separation change act (1967) expanded single parent and reconstituted families and diminished the family unit. Additionally new family structures, same sex families have been presented on account of approaches and change in perspectives. There might be new family structures later on as society advances.

A New Generation of Native American Writers Critical Linking, February 26
A New Generation of Native American Writers Critical Linking, February 26 Sponsored by Everything is Horrible and Wonderful by Stephanie Wittels Wachs Terese Marie Mailhot, whose new memoir, Heart Berries, came out this month, hates âpoet voice.â If youâve ever been to a poetry reading, or attended a creative writing class, or even just listened to Garrison Keillorâs The Writerâs Almanac on the radio, you know what sheâs talking about. Poet voice is sincere yet disaffected, a droning melody of self-importance. It is the standard, emulated by thousands of poets, essayists, and fiction writers, popularized and codified by creative writing programs across the nation. And like so many of those programs, it is extremely white. In this way, itâs a tidy metaphor for the way whiteness â" and expectations for what writing should sound like â" still dominates the writing world. This is an excellent profile of two new Native American authors. Go buy their books! Cooks, cookbook lovers, food enthusiasts, and food eaters, gather âround! The Piglet Tournament of Cookbooks is ready to rumble. Below, youâll find our list of the 16 cookbooks that absolutely knocked our socks off in 2017, as well as the judges who will be vetting them. From now through April, these books will be going head-to-head in what promises to be an intense competition. A cookbook tournament! I never read text that addressed [depression] in my community. There was never a character that I could point to and say that was someone who is experiencing this condition.

What Behavioral Techniques for Children Would You Use - Free Essay Example
Childrens Behavior: Techniques Take a moment and think. If you had a child, what behavioral techniques would you use? Do you know of any behavior techniques? Punishment by application, punishment by removal, problems with using punishment, and how to make punishment more effective are a few of the behavioral concepts and techniques well discuss. What is punishment by application? Punishment by application is when an action, like spanking or yelling is applied to the situation. Therapists discourage punishment by application because the situation is often taken out of hand, leading to abuse. Dubowitz and Bennet shared that spanking is harmless with a swat or two to the butt, but it turns into abuse when a belt or other item is used as a weapon to smack the child. The opposite type of punishment to punishment by application is punishment by removal. Instead of introducing something into the situation like the prior punishment, this is the removal or something valued to the child. Something of value to the child might include television, cell phones, or video games. Grounding your child from these valuable things would be an example of punishment by removal because you are removing something they like, not allowing them to use those items or do something they enjoy for a specific period of time. As always, with anything, there are flaws to using punishment. Punishment can be either good, and effective, or bad, and not so effective. First, you ought to know the difference between reinforcement and punishment. Reinforcement is when you encourage something that is already known. An example of this would be encouraging and reminding your child that they must keep their grades up or they will lose their video game privileges. On the other hand, puni shment is the act of weakening a response, which would be some type of bad behavior. Punishment doesnt always solve the behavior issue though, as the child might think that once the punishment is over, it is okay to behave like that again. Problems with physical punishment has flaws because the child may become scared of the punisher, avoiding them, and instead gets the wrong message. This kind of punishment is usually not successful because the child believes that if they misbehave they will be hurt. This is wrong. A child should learn from the situation; understand that what they did was wrong. It is hard to learn right from wrong when being abused or threatened. Along with abuse, comes lying. If the child knows that he or she will be hurt and abused when they do something wrong, they may begin to lie to try and avoid punishment. And as noted before, abuse only brings fear to the child. A child should be able to learn from mistakes. They should look up to their parents, or guardian and learn from what they did wrong, not think they will get abused for messing up. A buse creates fear and anxiety. Fear and anxiety slow down learning and halt it in its tracks. Also, an abusive parent only becomes an abusive role model. Instead we should be teaching children peace, the opposite of harm. How do you instead, make punishment effective? Its simple, three easy steps. 1. Punishment should be given directly after the bad behavior. If this is not done, then the punishment will not be seen as it was related to the bad behavior. 2. Punishment should always stay consistent. For example: if a mother tells her son that if he has bad grades, he will lose his playstation privileges, then she needs to do just so. And finally, punishment should always be followed with reinforcement regarding the correct behavior. For example instead of yelling at your child for peeing their pants, instead remind them that they are a big kid and use the potty. When they use the potty, praise them. Although there is much more to child behavior and related techniques outside of this essay, there is still valuable information and resources within. Punishment by application or removal are just a few techniques out of many ways children can be punished. Also, understanding the problems with punishment and the most ways to make punishment effective, allows the parent or guardian to help the child learn and grow most efficiently.

Roger gathered a handful of stones and began to throw them. Yet there was a space around Henry Here invisible yet strong, was the taboo of the old life Rogers arm was conditioned by a civilization that knew nothing of him and was in ruins. (Golding 62) Our environment has much to do with the way we react during different situations, yes, but is it the main reason for our behavior? In the book The Lord of the Flies, a group of young boys are stranded on an island without any adult supervision. Donââ¬â¢t waste time! Our writers will create an original "Lord of the Flies Essay Nature v. Nurture" essay for you Create order The author takes us through the story by demonstrating what happens when adolescents must depend on themselves without the comfort of civilization. The boys actions throughout the novel are not so much impacted by the environment, but the fact that their inner savages are finally able to roam free due to the absence of authority figures. During our upbringing we learn the ways of life from authority figures present in our childhoods like parents and teachers, but during our teenage years is when everything starts to change. Amanda Leigh Mascarellis article, The Teenage Brain, discusses the many different factors of the human brain that contribute to our everyday thinking and actions. During the risk-taking and rewards-based tests, one region deep inside the brain shows more activity in adolescents than it does in children or adults, Crone says. That one region is called the ventral striatum and is often called the reward center of the brain. This is because it moves us to repeat actions that receive rewards. In the boys case, their horrific actions resulted in one major treat, staying alive. Another region of the brain called the prefrontal cortex plays an important role in our decision making too. The prefrontal cortex is sometimes referred to as the master planner; it gives instructions and enables chatter among other brain regions. In the heat of the moment â⬠even when they know better, the reward system can outmuscle the master planner. That can lead to poor decisions, Casey says. This further explains the reason why the boys always give into temptations like playing instead of building a rescue fire. Adolescents are particularly sensitive and responsive to influence by friends, desires and emotions, researchers say. The sense of an authority figure played a large role in the sequence of the book. Nearing the end of the book, Jack takes matters into his own hands by creating his own tribe. Jack offers food, protection, and play, which all appeal to the ?bigguns, resulting in them leaving Ralphs side. Hes a proper chief, isnt he? Hes going to beat up Wilfred He got angry and made us tie Wilfred up. Hes been tied for hours, waiting (Golding 159) Jack decided to assert his power onto his tribe and treat them as if they were his minions. Of course, his tribe didnt mind because the boys were under the impression that Jack was the closest thing they had to a parental figure on the island. Prior to adolescence, the master planner isnt quite advanced enough to guide all the other brain regions. Thats because it still doesnt know the rules of the game. So thats why you have parents to act as your prefrontal cortex, During their time on the island, the boys closest thing to a parent figure was Jack, which explains why they made such rash decisions under his control. Some might say that the boys actions on the island were the result of long-term exposure to such a harsh environment. Kendra Cherrys article The Milgram Obedience Experiment states, The social psychology of this century reveals a major lesson: often it is not so much the kind of person a man is as the kind of situation in which he finds himself that determines how he will act. This statement can be refuted. Although environment does play somewhat of a role in bringing out our evil natures, biological factors and our individual ways of thinking have the biggest say in all of this. Dopamine levels in general peak during adolescence. In teenagers, the strength of this feel good response helps explain why they often give in to impulsive desires. To sum things up, the boys actions at the end of the book The Lord of the Flies are due to biological and mental factors as opposed to their surrounding environment and upbringing. The environment around us doesnt contribute to the making of our inner evil, but aids in bringing out the savageness within us. Our mentality and state of mind are the biggest contributors when it comes to decision making and the course of our actions.

Arm Fat Surgery Cost All You Need For Know Before...
Arm Fat Surgery Cost: All you Need to Know Before Undergoing the Procedure Arm fat surgery or brachioplasty is one of the most common elective surgery procedures performed in the United States. There are many questions people contemplating the procedure ponder about, one of the most obvious ones being the cost. In this guide you will find comprehensive information about arm fat surgery cost, what factors determine the charges, where to find the best services for the least cost and how you should pay for it. 1. How Much Does Arm Fat Surgery Cost? According to the American Society of Plastic Surgeons, on average, an arm fat surgery procedure cost about $3,936 in 2014. However, you should not take this figure at face value as different surgeons include charges like medical tests or anesthesia in their quotes while others do not. In general, the total cost will depend on such factors as: *. Surgeon s fees *. The medical facility in which the operation will be performed *. Anesthetist charges *. Medication *. Tools, materials and equipment to be used in the procedure *. Post surgery garments *. Medical tests Once you get a quote from your prospective plastic surgeon, take time to inquire if all these charges are included in the quote or they will be included later. It is worth noting that arm fat surgery is a relatively simple procedure. In most cases, a direct incision under local anesthesia is enough to achieve the desired result.

The Great Gatsby Nick vs Gatsby Essay - 1001 Words
The Great Gatsby: Nick vs Gatsby Mainframe computers analyze information and present it so that the observer is able to make accurate observations. In The Great Gatsby, written by F. Scott Fitzgerald, the narrator, Nick Carraway, tells a story in which Jay Gatsby tries to attain happiness through wealth. Even though the novel is titled after Gatsby, Nick, just as a mainframe computer, analyzes the actions of others and presents the story so that the reader can comprehend the theme. Throughout the novel, Nick is the vehicle used to gather all of the pieces together to learn about Gatsby. Nick is a one of a kind in the novel. He also is the only character that changes in the novel from the beginning to the end. Nickâ⬠¦show more contentâ⬠¦He did not know that it was already behind him(189). Without Nick, Gatsbys true colors would not be shown and his behavior would be left not pondered. His presence from the beginning to the end of the novel is imperative. Nicks uniqueness parallels his importance in the novel. Nick is very unique and different from all of the other characters in The Great Gatsby. Most of the characters symbolize reckless people during the rip roaring twenties that only want to be in the fast lane and do not give a damn about others. Nick sticks out of this crowd like a sore thumb. Geographically, Nick was raised in the friendly middle-east, while the book takes place in the snobby east. Tom, which is a representative of the rich, casually has an affair with Mrytle while with Daisy. On the other hand, Nick does not get involved with Jordan extensively because he has not broken relations with his old girlfriend in Chicago. He promises himself that there (is) a vague understanding that (has) to be tactfully broken off before I (am) free(p64). As a result of Nicks and the other characters differing values, he is considered an outsider. Only several times is Nick invited to rich gatherings. When he is partying with the rich, he resents the fact that they merely drink and gossip. Nicks uniqueness is probably best illustrated by Gatsbys funeral.

I will have a pre-made product to show the class as an example, this type of resource can be passed around the class for all to see the method used in construction. I am able to offer assistance to those pupils who I feel may lack in confidence with practical activities, as this type of exercise will allow me to move around the classroom and see learners progress on a one to one basis. The affective domain learners will gain from personal tuition, and in return will be able to complete this exercise. As I go from person to person giving advice and hands on help, I can also mentally assess those learners in the other two domains as I see them progress. My learning objectives will be: These are obtainable and I will know that they have been achieved by the end of the lesson, through the learners answering questions and once learners have successfully made the F-16. As this is my first teaching experience I will be nervous but will teach with confidence, I have thoroughly researched this topic, and therefore have a strong basis of the topic being taught. Learners will see that I have a great knowledge of the subject and this will be portrayed throughout the lesson. I will achieve this by having correct posture, effective body language, and will use eye contact; I will use my voice to maintain a steady pace so that my language will flow. Whatever happens you need to cultivate a confident exterior, even if it is something of an act and you are feeling far from assured inside. â⬠(Capel, Leask Turner 2005) References Capel, S Leask, M Turner, T 2005, Learning to teach in the secondary school: a companion to school experience, London ; Routledge Kolb learning cycle [Online].

Racial Profliling Essay Essays - Offender Profiling,
Racial profiling must be stopped this is something that people around the world have had to deal with more and more. Stop stereotyping people do not make and assumption based on the color of someone's skin their ethnicity or religion everyone must be treated just as equal as other men and other women. In the united states this is a very big problem mainly because people of color are targeted by the law enforcement. All over the U.S this is a recurring problem and their has been stories of people of color not even being able to walk on the street or not being able to drive the vehicle that they bought without law enforcement stopping them or checking who the car is registered too. This is something that shouldn't even be a problem this outright just should not happen. He who gives himself entirely to his fellow-men appears to them useless and selfish; but he who gives himself partially to them is pronounced a benefactor and philanthropist (Thoreau C.D 14). This speaks to me because it is saying that a if you give someone all your information than you are useless after and selfish if you do not but if you give small points of yourself than they become more intrigued and will see you as useful to them . This is the same case with people like police officers they ask who you are and what you are doing and they want that information to see if you really are a bad person or not but the truth is that in the first place they probably shouldn't have stopped you at all but because of your appearance they make an assumption about you. Think about it is the world really equal because no one is treated fairly especially with law enforcement. When was the last time you heard a person of color be the same as the common man it's not right and it needs to change. All through history there has been racial profiling history has showed us this with the Fugitive Slave Act what is this you might ask well this made it so that if you were a slave that had escaped and left to a free state you must return to your owner. This caused many people of color to be taken if if free they would have been abducted taken from their family and get enslaved. How can we allow such things to happen. How can the United States be proud of this when we have not even been able to bring equality for all . Think Martin Luther King, great man fought for civil rights and was very peaceful but was treated very differently by law enforcement and by government because he was a colored man we speak of him to this day because of the change he has brought to our world it was beautiful it warmed hearts and gave hope even to people that we not of color they joined together and did something good but it is like we have came back to square one in a way. Law Enforcement is not the only thing that racial profiles you also see this in school if you believe it or not it is up to you. Teachers also make assumptions on the people they see the staff does the same but you may not notice it. There was a study and it showed that black student were about 4 times more likely more to get suspended or expelled can you tell me this is not partially due to racial profiling and everyone hates to see it especially the parents of these children. Racial profiling of colored students is just terrible we must change this because think about the people who aren't doing wrong but are put into the same category of people that are actually bad just because of the color of their skin. We must make a change and it all starts with us becoming better people.Law enforcement must change how they see people and should start to see people as one and not give people of color unequal treatment. In Conclusion to stop racial profiling not only do you need to change the

What Makes a Good Villain Heres Your 15-Item Checklist
What Makes a Good Villain Heres Your 15-Item Checklist What Makes a Great Villain? Your Checklist for Writing a Good Bad Guy Nothing makes your hero more heroic than a worthy opponent. So donââ¬â¢t shortchange your villain. Spend every bit as much time crafting him as you do your lead character, if you want your story to work. (Though I will use male pronouns throughout, this applies equally if your main character is a heroine or your villain is female.) Too many novelists give plenty of care to every other element of their story, then create what they consider a deliciously evil villain and wonder why the package seems to fall flat. Often itââ¬â¢s because the bad guy is only that: bad. Heââ¬â¢s from Central Casting and might as well be starring in a melodrama, complete with black top hat, cape, and handlebar moustache so we readers can boo and hiss his every entrance. Every other character is real and nuanced and believable, but the second-most important lead spoils the readerââ¬â¢s whole experience. Need help writing your novel?Click here to download my ultimate 12-step guide. Motivation: The Secret Sauce for Creating a Great Villain Donââ¬â¢t let the word scare you. Motivation doesnââ¬â¢t have to be some nebulous theatrical concept tossed about by method actors trying to get into character. It simply means your bad guy needs a reason for being the person he has become. If he isnââ¬â¢t working, itââ¬â¢s because youââ¬â¢ve made him the villain only because heââ¬â¢s a bad person. He does evil things because heââ¬â¢s evil. Thatââ¬â¢s too easy. Change your thinking. Try something revolutionary. If you just canââ¬â¢t understand truly villainous people, try this: Put yourself in their place. ââ¬Å"Wait!â⬠you say. ââ¬Å"Iââ¬â¢d rather see myself as the hero, doing the right thing because itââ¬â¢s the right thing, rising to the challenge, saving the day.â⬠Wouldnââ¬â¢t we all? Well, donââ¬â¢t knock this till youââ¬â¢ve tried it. Youââ¬â¢re writing along, and youââ¬â¢ve come to the place where your villain needs to act in some evil way. Your virtual online writing coach has urged you to be sure he has proper motivation. What does this mean? He canââ¬â¢t be bad, do bad, cause trouble just because heââ¬â¢s the bad guy, so whatââ¬â¢s made him this way? Whatââ¬â¢s behind it? You have to know before you have him do whatever it is heââ¬â¢s about to do. Take His Place ââ¬Å"But Iââ¬â¢m not a villain!â⬠you say. ââ¬Å"Iââ¬â¢m no Dr. Moriarty or Dracula or Simon Legree.â⬠Yes, you are. You have your days. Youââ¬â¢ve learned to control yourself, or maybe youââ¬â¢re a person of faith and have found control outside yourself. But you know your true nature, your old nature. We novelists need to become our characters, from young to old, male to female, blue-collar worker to executive, and illiterate to educated. Thatââ¬â¢s part of the fun of it. Now take that further. When a friend takes credit for something you accomplished, whatââ¬â¢s your first private thought? You get over it, I know. You probably say nothing and let it pass for the sake of the relationship, and thatââ¬â¢s great. But dwell on that initial visceral reaction a moment. Someone you know well and love and trust lies to you, and thereââ¬â¢s no question about it. Youââ¬â¢re offended, hurt- crushed really. In fact, youââ¬â¢re infuriated. You bite your tongue because youââ¬â¢re a mature adult. Maybe when you cool down youââ¬â¢ll rationally confront the lie and get to the bottom of it. But for now, entertain that immediate first reaction. Where was your heart and mind then? Iââ¬â¢m not telling you to become mean, rotten, and nasty when weââ¬â¢re all supposed to have grown out of that kind of thing by now. But I am telling you to tap into your dark side long enough to know what makes a good villain tick. What Makes a Good Villain? Villains are real people to whom terrible things have happened. Maybe in childhood, maybe in adolescence, maybe later. At some point, rather than learning and growing, their maturation process stunted and stalled. Roots of bitterness and anger sprang up in them. On the surface they may have many, if not most, of the same attractive qualities of your hero. But just beneath the surface fester the qualities you can access in yourself if you allow yourself to. While this may explain the reasons for your villainââ¬â¢s actions, it doesnââ¬â¢t excuse or forgive them. Heââ¬â¢s still evil, and he must still be brought to justice. But giving him motivation will make him more than a cardboard cutout. So conjure a backstory for your villain. Make him real and believable and credible- even attractive in many ways. And while youââ¬â¢re writing your story, see how many boxes you can check off on this list of characteristics that pertain to your villain. The more that apply, the more successful your novel is likely to be. Because the more worthy his opponent, the more heroic your hero will appear. Villain Characteristics Checklist: Heââ¬â¢s convinced heââ¬â¢s the good guy He has many likeable qualities Heââ¬â¢s a worthy enough opponent to make your hero look good You (and your reader) like when heââ¬â¢s on stage Heââ¬â¢s clever and accomplished enough that people must lend him begrudging respect He canââ¬â¢t be a fool or a bumbler He has many of the same characteristics of the hero, but theyââ¬â¢re misdirected He should occasionally be kind, and not just for show He can be merciless, even to the innocent Heââ¬â¢s persuasive Heââ¬â¢ll stop at nothing to get what he wants Heââ¬â¢s proud Heââ¬â¢s deceitful Heââ¬â¢s jealous, especially of the hero Heââ¬â¢s vengeful Need help writing your novel?Click here to download my ultimate 12-step guide.

National Intelligence Estimate (NIE) Policy Simulation Paper Essay
National Intelligence Estimate (NIE) Policy Simulation Paper -Counterintelligence - Essay Example In this battle which has social, budgetary, political, and political and also military sizes ââ¬â the potential outcomes of counterintelligence disappointments could be quick and destroying, putting in risk our countrys crucial data, base, military powers and an extensive variety of US investment, innovations and faculty far and wide (Goldman, 17-23). In 1978, an arrangement of informal trade visits between US atomic weapons specialists and their Peoples Republic of China (PRC) partners started. The PRC authorities endeavoured to grow close associations with specific US specialists. Over the consequent 23 years, as a consequence of this trade, the PRC made real strides in the improvement of atomic weapons, including the neutron shell. Starting in 1998, US media sources started reporting about continuous examinations of four instances of suspected Chinese surveillance against the United States going over to the 1980s. The most genuine case included Chinas claimed securing of key data about our countrys most developed (The Central Intelligence Agency). US atomic warhead, the W-88, and additionally genuine security breaks at the Department of Energys (DOE) Los Alamos Laboratory between 1984 and 1988 Early in 1998, Congressional center turned to US satellite fares to China. A US Department of Defence grouped report reasoned that researchers from Hughes and Loral Space and Communications, included in concentrating on the 1996 accident of a Chinese rocket propelling a Loral satellite, gave experimental skill to China that prominently enhanced the dependability of Chinas rocket propel capabilities. After this data was distributed in the US media, an extraordinary House Select Committee and various Senate panels researched US innovation exchange approach regarding China.

Hybrid Cultural Object Essay Example | Topics and Well Written Essays - 1250 words
Hybrid Cultural Object - Essay Example Language entails the sharing of ideas and thoughts from one person to the other. The culture of the language has been evolving from one community to another. The evolving nature of language has led to the object of communication being improved to a level of being termed as a hybrid language. The most common element of this tool is the use of signs and symbols to communicate. The use of signs has developed significantly due to the interaction of human beings from different regions around the globe. The pressure to find out an aspect of sign language that would unify different cultures in the region have led to the scientific study of signs; semiotics. Signs having been developing, and this study helps the human diversity to know how they are supposed to behave in a particular situation without there being a second person to engage in the verbal communication (Ipsen). The hybrid nature of communication in this state is that signs are being developed into a global unified way that every community get aligned to the communication base to one another. In other words, the signs developed are familiar to everyone around the globe. The global awareness and unity in communication have been established by the fact that there is an organised system that the signs follow. Since there is an organised way of communicating through the use of signs, every stakeholder in the signs language will follow the laid down system. The following of the laid down rules and regulations help different cultural groups to have a unified sign that helps in communication. When a person at one corner of the world sees an image or a picture representing, a situation will be able to give the meaning from the picture and interpret it. Therefore, a person can analyse the situation and act accordingly. It is the globally accepted picture that will help the reader to communicate accordingly in that situation. Signs as used in communication changes

Sucrose Synthase Key Enzyme In Sucrose Metabolism Biology Essay
Sucrose Synthase Key Enzyme In Sucrose Metabolism Biology Essay Sucrose synthase is a key enzyme in sucrose metabolism. Sucrose metabolism is required by the plant to form carbon required for various processes in the plant such as respiration, starch and cell wall formation. The enzyme is encoded by a small multigene family where most plants have at least two isoforms of the enzyme. The kinetics of sucrose synthase show that different Km values and ratios of sucrose breakdown exist for the enzyme. The methods of extracting, assaying and purifying the enzyme are shown in the enzyme characteristics. Factors such as pH, addition of different buffers, metal ions, fungal volatiles as well as environmental factors such as anoxia have all been shown to affect sucrose synthase activity. The enzymes protein sequences have been phylogenetically divided up into six main groups using clustalw. Sucrose synthase is normally present in the cytoplasm but the availability of sucrose in the chloroplast and its ability to use ADP as a substrate would indicate that the enzyme may be able to act in the chloroplast as well as the cytoplasm. Sucrose synthase is an important enzyme in sucrose metabolism in plants cells. (Persia et al., 2008) The main route of entry of carbon from sucrose is commonly known to be sucrose synthase. (Bieniawska et al., 2007) This carbon is used for respiration and in the synthesis of cell wall polymers and starch. (Persia et al., 2008) The main form of reduced carbon in plants is sucrose. It is used to support growth and synthesis of reserve materials e.g. starch in heterotrophic sink tissues. (Matic et al., 2004) The UDP-glucose supplied by sucrose synthase is used for cell wall biosynthesis while working with the cellulose synthase complex. (Baud, Vaultier and Rochat, 2004) In most fruit tissues, an increase in sucrose synthase activity is alongside with sucrose accumulation. This would suggest that sucrose synthase plays a physiologically important role. (Islam, Matsui and Yoshida, 1996) Carbohydrates are transported from photosynthetic source tissues to sink tissues in the form of sucrose . The consequent cleavage of sucrose in the sink tissues is the first step for its use in various metabolic pathways. The sugar is cleaved in vivo by either sucrose synthase (Sus) or by invertase. Invertase catalyses an irreversible reaction where sucrose is cleaved into glucose and fructose (Matic et al., 2004) while sucrose synthase catalyses the reversible conversion of sucrose and uridine-diphosphate (UDP) into uridine-diphosphoglucose and fructose. (Hirose, Scofield and Terao, 2008) (Hardin and Huber, 2004) These enzymes play a crucial role in plant growth and development. (Abid et al., 2009) Sucrose Synthase is cytosolic (Ã
ebkovà ¡ et al., 1995) and has been characterized in many different plant species such as maize (Hardin and Huber, 2004), rice (Odegard, Liu and Lumen, 1996) and sugarcane (Schà ¤fer, Rohwer and Botha (2005)). Its activity has been studied in many plant organs such as roots, leaves and seeds. (Ã
ebkovà ¡ et al., 1995) For trees, cellulose biosynthesis is a highly regulated process in which carbon is permanently placed in their primary and secondary cell walls. Sucrose is the main carbon source for cellulose synthesis. The stem is made up of extremely active sink cells which utilise sucrose for cellulose synthesis. Sucrose synthase is the main sucrolytic enzyme in these cells that catalyzes the reversible conversion of sucrose into fructose and UDP-glucose which is needed for cellulose biosynthesis. (Joshi, Bhandari and Ranjan, 2004) It also plays an important role providing adequate sugar supply during anoxic stress. It has been shown that during anoxic germination of rice, sucrose synthase activity was enhanced whereas the activity of invertase was depressed. This would indicate that sucrose synthase is the enzyme predominantly responsible for sucrose breakdown during anoxia. (Joshi, Bhandari and Ranjan, 2004) Fig 1: Diagram of the cleavage and synthesis reaction of sucrose synthase (Rà ¶mer et al., 2004) Different isoforms of the gene are present in most plants. In the case of maize, two non-allelic genes were discovered for sucrose synthase but more investigation lead to the discovery of a third. At least three genes for sucrose synthase have been discovered in rice where the genes show differences in expression between tissues. RSus1 is expressed in root phloem while RSus2 is expressed in leaf phloem. (Schà ¤fer, Rohwer and Botha, 2005) When examining the different isoforms at an amino acid level it is appears that there is less homology between different sucrose synthase genes in a species than when the gene is compared to its corresponding gene in another species. In the case of maize, there is 75% homology between the SS1 gene and SS2 gene of maize but there is 90% homology between rice RSus1 and maize SS2 genes. In sugarcane, the SS1 gene is 97% identical at the amino acid level to maize SS1 gene. (Lingle and Dyer, 2001) Nolte and Koch (1993) undertook a study to determine whether sucrose synthase was localized to certain part of the vascular strand. It is well known that sucrose synthase is present in vascular bundles for example in transgenic tobacco plants phloem specific expression of a maize sucrose synthase gene has been observed. Their study, using immunohistochemistry, found that sucrose synthase was restricted to the cytoplasm of companion cells of the phloem and did not appear to be present in other organelles of the plant. (Nolte and Koch, 1993) The molecular mass of sucrose synthase can be determined by gel filtration. Sucrose synthase elutes from the column with a Kav value of 0.17844 which when using a calibration curve correlates to a molecular mass of 362kDa. Using SDS-PAGE gradient gel the molecular mass of each subunit can be estimated at 92kDa. This can conclude that sucrose synthase is a tetrameric enzyme with a molecular mass of 360kDa and four identical subunits of 90kDa. (Hardin and Huber, 2004) (Elling and Kula, 1993) It can associate with membranes and the actin cytoskeleton where its activity is known to be involved with cellulose synthesis. It does this by channelling uridine-diphosglucose to the growing glucan chain by the enzyme cellulose synthase. (Hardin and Huber, 2004) Analysis of Sucrose Synthase Gene Family: From the results of species examined to date, it is shown that sucrose synthase is encoded by a small multigene family. (Bieniawska et al, 2007) Most species of plants have at least two isoforms of sucrose synthase. These isoforms usually have comparable biochemical properties and highly homologous amino acid sequences. (Wen et al., 2010) Further analysis of transgenic and mutant crop plants show certain isoforms of sucrose synthase have specific functions in the plant. The rug4 mutation of pea removes the SUS1 isoform but has no effect on SUS2 or SUS3. This would indicate that these two isoforms are not able to make up for the loss of SUS1 in the seed or root nodule. It is clear that the loss of different isoforms affect the plant in certain ways. Loss of the SH1 isoform in maize has different outcomes from the loss of SUS1 isoform. SH1 is required for normal cell wall formation during endosperm development while both isoforms are needed for wild-type rates of starch synthesis. Why different isoforms have different functions is unclear. The same functions can be carried out in the cell by different isoforms but can occur in distinct cell types, developmental periods or environmental conditions. It is likely that different isoforms could have non-overlapping, particular functions in the same cell. (Bieniawska et al., 2007) It is difficult to decide on the precise roles of the genes in sucrose synthase gene family when there is not enough information in existence. Although there is some information available on some of the isoforms and theyre functions in the plant, no analysis of the functions of the gene family has been carried out. The model plant Arabidopsis is ideal for carrying out such an analysis. Six sucrose synthase genes are in the Arabidopsis genome. Based on comparisons of the amino acid sequences the isoforms they encode can be divided into three distinct pair groups. The isoforms SUS1 and SUS4 are 89% identical to each other but have less than 68% similar amino acid sequences to other isoforms. Similarly, SUS2 and SUS3 are 74% identical to other isoforms and are 67% less identical to the other forms of enzyme. SUS5 and SUS6 are 585 identical to each other but have less 48% similarity to the other isoforms. When examining other dicotyledonous species it appears that at least two of the thr ee pairs of isoforms are present. When phylogenetic analysis was carried out, it showed that the isoforms AtSUS1 and AtSUS4 are related to pairs of isoforms from pea (Fabacae), carrot (Umbelliferae) and potato (Solanacae). A pair of isoforms from Craterostigma plantagineum (Scrophulariacae) is closely related to the pair of isoforms AtSUS2 and AtSUS3 in the Arabidopsis. The pair AtSUS5 and AtSUS6 is related strongly to a pair of genes from rice. This evidence shows that it is unlikely that the three pairs of isoforms in Arabidopsis are as a result of gene duplication events. It is possible that each isoform has an exact function preserved in a wide range of plants. The members of Arabidopsis gene family are strongly differentially expressed in different organs of the plant through its development and in response to external stimuli e.g. environmental stress. This is seen in gene families of other plants studied. (Bieniawska et al., 2007) Fruit quality is determined by the type and quality of sugars present. A study of the sucrose synthase-encoding gene from the muskmelon fruit was carried out to evaluate how to genetically improve the quality of the fruit. This is done by finding the sugar components in fruit, to identify the enzymes involved in sugar metabolism and distinguish the relationship between sugar accumulation and the activities of related enzymes. It is thought that sucrose synthase is the enzyme involved in metabolising sucrose in developing muskmelon fruit. To examine this, a full length cDNA strand encoding sucrose synthase was extracted from a muskmelon fruit by RT-PCR and RACE and identified as CmSS1. Real time PCR analysis showed that CmSS1 expression changed in among different tissues of the plant e.g. root, stem, leaf. It showed that the mRNA levels are highest in the root and lowest in mature fruit. Fig 2: The patterns of CmSS1 transcript abundance in the different tissues of the muskmelon plant. These results were found using quantitative real-time PCR analysis of total RNA prepared from the root, stem, leaf, flower and mature fruit of muskmelon. During fruit development and ripening it was shown that CmSS1 mRNA was at its maximum level at five days after pollination and decreased steadily during fruit development until it reached its minimum level of maturity. This was discovered using again real-time RT-PCR analysis of mesocarp tissues from five days of pollination to ripening. Fig 3: This graph depicts the patterns of CmSS1 transcript abundance in developing muskmelon fruits found by using quantitative real-time PCR analysis of total RNA prepared from muskmelon. (Wen et al., 2010) The sugar content and SS activity were analysed to show the functions of CmSS1 in regulating fruit quality. It showed that very low concentrations of sucrose are present in young and unripe muskmelons. Between 20 and 30 days after pollination there is a massive rise in the amount of sucrose in the fruit. Sucrose synthase activity increased in the direction of sucrose synthesis and decreased in the direction of sucrose cleavage through fruit development. (Wen et al., 2010) Fig 4: The depiction of sucrose content and sucrose synthase activity during muskmelon fruit development. The first chart shows sucrose content during fruit development. The second shows sucrose activity in the sucrose synthesis direction and the third shows sucrose cleavage direction during muskmelon fruit development. (Wen et al., 2010) Enzyme Kinetics of Sucrose Synthase: An investigation was carried out by Schà ¶fer et al. to the find the properties of three sucrose synthase isoforms present in sugarcane. Kinetic analysis indicated that the three sucrose synthase genes in sugarcane are different isoforms, with major differences in Km values and the ratios of sucrose breakdown synthesis. The kinetic characteristics of the SuSyA and SuSyB isoforms, both expressed in the leaf roll, differ greatly. It was found that SuSyA has almost three times higher affinity for sucrose than the SuSyB isoform whereas SuSyB has a much greater affinity for UDP than SuSyA. Based on the differences in their kinetic properties it can be concluded that SuSyB and SuSyC are different isoforms of sucrose synthase. SuSyC has roughly ten times higher affinity for UDP compared to the other two isoforms. (Schà ¤fer et al., 2005) Fig 5: The graph shows the Lineweaver-Burk plot of 1/v against 1/S for the isoforms SuSys A, B and c where UDP was the variable substrate. The concentration of sucrose was kept constant at 320nM. The Km values were determined from the non-linear fit of the data to the Michaelis-Menten equation. (Schà ¤fer et al., 2005) When examining sucrose synthase in soybean nodules Morell and Copeland (1985) found the kinetic constants of UDP, UDPglucose, sucrose and fructose by fitting the data to the following two equations: 1. v = VA/KiaKh + KhA + KhB + AB 2. v = VA/Ka + A + A/Ki The kinetic constants for ADP, CDP and ADPglucose were found using non linear regression analysis of initial velocity data. Fig 6: Graph showing the effect of sucrose concentration on the cleavage activity of sucrose synthase in soybean nodule. The lines show the fit of data to equation 1. The reaction mixture were composed of 20à µmol Hepes-KOH buffer (pH 7.5) 2à µmol UDP, 1.5à µmol NAD, 25à µg UDPglucose dehydrogenase. Each symbol represents a different concentration of sucrose. The dark circle shows 3.2à µM, the clear circle shows 4à µM, the dark triangle shows 6.25à µM, 10à µM is shown by the clear triangle and the dark square depicts 20à µM. In the cleavage and synthesis direction standard Michaelis-Menten kinetics are observed. The variation of concentration of sucrose at different concentrations of UDP gave an intersecting pattern of linear double reciprocal plots. (Morrell and Copeland, 1985) Parameter Value V (U/mg protein) 13.3à ±2.0 Km sucrose (mM) 31.3à ±7.1 Ki sucrose (mM) 31.9à ±13.1 Km UDP (mM) 0.005à ±0.002 Ki UDP (mM) 0.005à ±0.001 Fig 7: Table showing the kinetic parameters for the cleavage reaction of sucrose synthase in soybean nodules. (Morrell and Copeland, 1985) Fig 8: The graph depicting the effect of UDPglucose concentration on the synthesis reaction of sucrose synthase activity in soybean nodules. The reaction mixtures contained 20à µmol Hepes-KOH buffer, 15 à µmol fructose, 5à µmol MgCl2, 0.4 à µmol P-enolpyruvate, 0.15 à µmol NADH, 20à µmol KCl, 25à µg pyruvate kinase 25à µg lactate dehydrogenase and the required amount of enzyme. As in the previous graph, the amount of UDPglucose was varied in the presence of 2.5mM (dark circle), 3.2mM (clear circle), 4mM (dark triangle), 5mM (clear triangle) and 8mM (dark square) fructose. The results on the graph are representing the fit of data to equation 1. When the concentration of UDPglucose was varied at the concentrations of fructose in the graph, an intersecting pattern of linear double reciprocal plots was seen. From fitting the data from the graph to equation 1, it is noted that substrate inhibition would have occurred at a concentration greater than 15mM fructose. Parameter Value V (U/mg protein) 14.3à ±1.2 Km fructose (mM) 3.7à ±0.8 Ki fructose (mM) 19.6à ±9.9 Km UDPglucose (mM) 0.012à ±0.006 Ki UDPglucose (mM) 0.064à ±0.014 Fig 9: table showing the kinetic results by fitting the figures from the graph to equation 1. When partially purified SuSyA, SuSyB and SuSyC were blotted to a nitrocellulose filter the results showed that all three isoforms are approximately 94kDa. (Schà ¤fer et al., 2005) The would correlate to the findings of Hardin et al and Lothar et al who stated that sucrose synthase is tetrameric enzyme made up of four 90kDa subunits. Fig 10: Immunoblot of sugarcane SuSy. A crude extract of protein from leaf roll was loaded into lane 2 while partially purified isoforms of SuSyA, SuSyB and SuSyC were loaded to lane 3, 4 and 5. The molecular weight ladder was used to identify the bands see in each lane. (Schà ¤fer et al., 2005) Characteristics of Sucrose Synthase: Extraction of Protein: The method for extracting protein from the leaves of maize (Zea mays), rice (Oryza sativa) and tobacco was done as follows: 1-3g of leaves was ground in liquid nitrogen and the powder was mixed in the ratio 1:2 with extraction buffer. The buffer was made up of 0.1M tris-HCl, pH 8, 10mM DTT and 1% polyvinylpolypyrrolidone. The samples were then incubated on ice for 15 minutes and then centrifuged at 1,000g for 10 minutes at 4oC. The pellet was then removed and the supernatant was re centrifuged at 100,000g for one hour at 4oC. After this final centrifugation, the pellet and supernatant which contained the soluble proteins was resuspended in sample buffer for electrophoresis. (Persia et al., 2008) When extracting protein from rice seeds, a similar procedure is followed. Seeds weighing roughly 50-100mg at various stages of growth were homogenized in 400à µl of extraction buffer and kept at 4oC. The buffer was made up of 50mM Tris-HCl, pH7.5, 1.0mM DTT, 1.0mM EDTA and 2mM PMSF. Ammonium sulphate fractions (30-50% w/v) were precipitated and then resuspended in dialysis buffer made up of 50mM Tris-HCl, pH 8.0, 5mM MgSO4, 5mM 2-mercaptoethanol. This was then dialyzed overnight at 4oC. (Odegard, Liu and De Lumen., 1996) The method for extracting protein from tobacco pollen tubes is slightly different to those mentioned previously. The pollen first was slowly thawed from storage at -20oC and hydrated in a humid chamber overnight. It was then germinated in BK medium and allowed to germinate at 25oC for three hours. After this period had elapsed, the pollen was collected by centrifugation at 1,000g for 5 minutes at 25oC. It was then washed twice with BRB25 buffer which is made up of 25mM HEPES, pH 7.5, 2mM EGTA and 2mM MgCl2 and 15% Suc. After washing, the pollen was resuspended in lysis buffer and lysed on ice using a motor-driven Potter-Elvehk-jem homogenizer. The lysis buffer used was made up of BRB25 buffer along with 2mM dithiothreitol, 1mM phenylmethylsulfonyl fluo ride (PMSF), 10à µL/mL protease inhibitors, 1mM NaN3 and 10% mannitol. After lysis was carried out, the samples were centrifuged at 1,000g for 10 minutes at 4oC. The supernatant was centrifuged again at 4oC for 45 minutes at 100,000g over a 20% (w/v) Suc cushion. The supernatant was then collected as it contained the soluble protein fraction. (Persia et al., 2008) Enzyme Assays: After extracting protein, the sucrose synthase activity in sugarbeets was found using a spectrophotometric end point assay. The activity of the enzyme was monitored as fructose formed at 35oC. This was carried out in a solution that contained 250mM sucrose, 2mM UDP and 100mM MES. The control was carried out by assaying for activity in the absence of UDP. The total protein concentration was determined using the Bradford method where bovine serum albumin was the standard. (Klotz and Haagenson., 2008) When assaying for protein from rice, the Bradford method was followed to determine protein concentration as was done in Klotz et al. 40mg of protein was used per assay. The assay was carried out in 20mM MES pH 6.4, 200mM sucrose and 4mM UDP for 15 minutes at 30oC. The reaction was stopped by boiling for 2 minutes and the fructose levels were measured. The control tubes did not contain UDP. (Odegard, Liu and De Lumen., 1996) When examining the effect of sucrose synthase on carbon partitioni ng a similar method was followed for assaying the protein. Sucrose synthase was assayed in the direction of sucrose breakdown using 50à µl poplar plant extract. The tetrazolium blue assay was followed to determine the amount of free fructose. As in previously mentioned assays, the absence of UDP in the assay acted as a control. The total protein content was found by employing the Bradford (Bio-Rad) protein assay. (Coleman, Yan and Mansfield., 2009) A similar method was followed for carrying out an assay for the enzyme on tomato tissue. The reaction mixtures contained 50mM Hepes-NaOH buffer, 15mM MgCl2, 25mM fructose and 25mM UDP glucose. This was incubated at 37oC for 30 minutes and was terminated with the addition of 70à µl of 30% KOH. The enzyme blanks were terminated with the addition of KOH at 0 minutes. The tubes were then kept at 100oC for 10 minutes to destroy any fructose. The soluble protein content was determined using the Lowry method whereby bovine serum albumin was th e standard. (Islam, Matsui and Yoshida., 1996) Alkaline copper solution is added to each tube and allowed to stand at room temperature for roughly 30 minutes. Dilute folate reagent is then added to each tube rapidly and after 30 minutes the absorbance is read at 750nm. (Lowry et al., 1951) The results were measured as à µmole of sucrose per minute per mg protein. (Islam et al., 1996) When assaying for sucrose synthase in the cleavage direction Rà ¶mer et al used recombinant SuSy1 gene from potato. In a volume of 100à µl HEPES buffer with a concentration of 200mM and pH 7.6 recombinant sucrose synthase was incubated along with 2mM UDP and 500mM sucrose for ten minutes at 30oC. HPLC analysis was used for the formulation of UDP-glucose. The Bradford assay was used to determine protein concentrations as was carried out by Klotz et al and Coleman et al. The activity of the enzyme was also tested with the nucleoside diphosphates dTDP, CDP, ADP and GDP at 2mM. For assaying recombinant e nzyme in the synthesis direction a similar method was followed as when assaying for standard enzyme. Recombinant sucrose synthase was incubated in a total volume of 100à µl HEPES buffer where this time the pH was 8.0 and the concentration was as in cleavage direction of 200mM. 1mM UDP-Glc and 20mM D-fructose was also added to the mixture and it was incubated for five minutes at 30oC. The reaction was heated to 95oC for five minutes and HPLC analysis was used to establish the formation of UDP. The sucrose synthase activity was also tested using dTDP-Glc, CDP-Glc and ADP-Glc. (Rà ¶mer et al., 2004) Purification of Protein: After extraction of the protein from the crude extract, purification can be carried out. This can be done in a number of ways such as Batch adsorption with Sephadex A50, Anion exchange chromatography and Gelfiltration. SDS-PAGE can be carried out after purification to check the purity of the protein sample. The Sephadex A50 gel is loaded into a glass funnel and washed twice with deionised water. The gel was then washed twice with 300ml standard buffer. The protein sample was loaded to the gel and slowly sucked through the gel for 30 minutes. The gel bed was then washed with 300ml standard buffer and then with 300ml standard buffer containing 100mM KCl. The last washing step contained 300mM KCl. 200ml of the first salt preparation was concentrated to 40-50ml by using a cross-flow ultrafiltration module with YM 30 ultrafiltration membrane that had been pretreated with 55 PEG 4000 solution. This was done to prevent the enzyme sticking to the membrane. In anion exchange chromatography a Sepharose Q column was first equilibrated with 300ml Hepes buffer. This was made up of 200mM pH 8 with 50mM KCl. 70-80mg of protein sample was loaded and the elution was started using two different salt gradients. To prevent enzyme inactivation after elution all the fractions were titrated back to pH 7.2. All fractions that contained enzyme activity were pooled and concentrated by using ultrafiltration. Gelfiltration experiments are carried out on a prepacked HiLoad 16/60 Superdex 200 prep grade column that was connected to FPLC equipment. Four samples containing 2mg of protein were loaded and eluted with a flow rate of 1 ml min-1. The fractions were then pooled and stored at -20oC in 500à µl aliquots. (Elling and Kula., 1993) To determine the purity of the protein, SDS-PAGE is carried out. This is done by loading 100à µg of protein samples to a 125 SDS-polyacrylamide slab gel that was overlaid with stacking gel. The electrophoresis was carried out at 4oC and at 40V for 16 hours a nd followed by 200V for one hour. Coomassie blue R 250 was used to stain the gel followed by destaining. (Kumutha et al., 2008) Factors that affect Sucrose Synthase Activity: Ã
ebkovà ¡ et al (1995) stated that sucrose synthase has two different pHs for optimal activity. In the cleavage direction it was found that most enzyme activity was observed between pH 6.0 and 8.5 at temperatures between 50 to 55oC. In the synthesis direction, a pH between 8.5 to 9.5 and a temperature of 35oC was optimal for enzyme activity. (Ã
ebkovà ¡ et al., 1995) This would correlate with the findings of Morell and Copeland (1985) who found that optimal activity of the enzyme in soybean was at pH 6 in the cleavage direction and at a pH of 9.5, sucrose synthase activity in the synthesis direction was at its highest. It was also found that at a pH of 7.5 the cleavage and synthesis activities were their highest. (Morrell and Copeland., 1985) Elling and Kula (1995) examined the effect of buffers TES-NaOH, MOPS-NaOH, TEA-NaOH and Tris-HCl on the pH optimum of sucrose synthase activity. These were determined using UDP and TDP as substrates for the reaction. They found that the e nzyme had its highest activity in Hepes-NaOH buffer. When MOPS-NaOH and TES-NaOH buffer was used, only 60-80% activity was noted. (Elling and Kula 1995) It was also found that the velocity of the reaction could be increased by increasing the temperature where optimal activity was seen between 50 and 60oC. Xu at al (1989) reported that potato and bean are also able to withstand these high temperatures. However once the temperature goes above 60oC enzyme activity starts to decreased rapidly and was destroyed once the temperature reached 70oC. (Xu et al., 1989) The cleavage of sucrose by the sucrose synthase enzyme was investigated to find the rate of cleavage reaction using different nucleosidediphosphates as cosubstrates. They found that the rate of reaction was UDP>TDP>ADP>CDP>GDP. Echt and Chourey (1985) found similar results when examining nucleotide specificity. They found that substrate specificity for SS1 and SS2 were UDP>TDP>ADP>CDP>UTP where each substrate was at a concentrat ion of 4mM. (Echt and Chourey 1985) Low levels of heavy metal ions such as mercurate inhibited cleavage activity of the enzyme. This would lead to the assumption that sulfhydryl groups are involved in the catalytic process. It is also inhibited by Tris-HCl and by small concentrations of MgCl2 and MnCl2. (Ã
ebkovà ¡ et al., 1995) Cations were shown by Elling and Kula (1995) to have a slight influence on enzyme activity. The activity was lessened slightly (10%) by the presence of 1mM Mn2+ and Mg2+ ions with UDP. The enzyme is completely inactivated in the presence of 1mM Cu2+ or Fe2+. (Elling and Kula., 1993) A recent study was undertaken to examine the effects of volatile emissions on carbohydrate metabolism. Studies on this area have taken place before but it is usually examining the results of physical contact between the host plant and the microbe. No work has taken place until now on the effect on the plant in the absence of physical contact. Many microbes such as Pseudomonas spp, Strepomyces spp, Penicillin spp and a selection of truffles produce ethylene. This gaseous plant hormone plays an important role in many aspects of plant growth and development such as seed germination, root hair initiation, fruit ripening and starch accumulation. In the work of Ezquer et al (2010), the possible effects of volatiles released from gram-negative bacteria, gram-positive bacteria and fungi on starch metabolism was studied. The results showed that the volatile compounds released by microbes promoted high levels of starch accumulation in mono- and dicotyledonous plants. It also revealed fungal vo latiles (FVs) promoted massive changes in expression of genes involved in many important processes in plant such as metabolism of carbohydrates, amino acids, sulphur and lipids, energy production, protein translation and stability, cell wall biosynthesis and photosynthesis. However no changes were noted in the expression in some of the genes that coded for proteins involved in starch and sucrose metabolism such as plastidial hexokinase, plastidial phosphoglucose isomerase, plastidial adenylate kinase, alkaline invertase and UDPglucose (UDPG) pyrophosphorylase. It was found in the study that FVs strongly upregulate the expression of Sucrose Synthase in potato leaves. The plants were cultured in the presence and absence of FVs emitted by A. Alternata. This caused a massive enhancement of expression of Sus4 isoform. A 29.4- and 31.63-fold increase was observed in expression when the plants were cultured in the presence and absence of sucrose. This isoform of the enzyme controls the accumulation of ADPG, UDPG and starch in potato source leaves and tubers. Analyses of the intracellular amounts of starch and nucleotide-sugars in the leaves of the plant show a positive correlation between patterns of enzyme activity and starch, UDPG and ADPG amounts. This was noted when the leaves were cultured in the presence and absence of FVs. Western blot analyses and quantitative RT-PCR confirmed also the increase in expression. (Xu et al., 1989) Environmental Factors affecting Sucrose Synthase Activity: Anoxia: Waterlogging is where oxygen supply is blocked to root leading a severe decrease in the amount of oxygen available to the plant. This leads to inhibition of root respiration that causes a major decline in energy of root cells affecting vital metabolic processes of the plant. This is restriction of oxygen supply is known as anoxia. The presence of glucose in an anoxic incubation medium drastically decreases meristem death and studies have shown that sucrose synthase is the enzyme mainly responsible for sucrose breakdown under anoxia. (Kumutha et al., 2008) The increase in glycolytic demands caused by these demands is the cause of increased sucrose synthase expression. This has been demonstrated in many plant species e.g. sucrose synthase gene is induced in wheat and in rice when oxygen levels are low. (Ricard et al., 1998) Harada et al (2005) also found an increase in sucrose synthase activity in pondweed turins while under anoxia. (Harada et al., 2005) Klotz and Haagenson (2008) foun d that sugarbeet contained two genes for sucrose synthase activity-SBSS1 and SBSS2. They demonstrated that anaerobic conditions caused a large increase in the transcription levels of SBSS1 and a quick increase and succeeding decline in SBSS2 transcription levels. However this did not correlate with a significant increase in sucrose synthase enzyme activity. A 23% increase in sucrose synthase activity was noted after initiation of anaerobic conditions but otherwise the activity of the enzyme did not differ greatly to that of the controls. (Klotz and Haagenson., 2008) Fig 11: The graph outlines the different rates of sucrose synthase activity in the con
