It was the birth of the Digital Revolution which saw massive advances in technology. Donââ¬â¢t waste time! Our writers will create an original "Emotional Intelligence And Why It Is Critical to Your Success" essay for you Create order We also began to better understand us as humans- most importantly why some succeeded and others, although very promising, didnââ¬â¢t. Until the 1960s and 70s, it was widespread belief that those with the best diploma ââ¬â the ones with the highest IQ ââ¬â were destined for success. The world was understandably confused when this belief was shaken by incredibly successful entrepreneurs such as Ray Kroc, Warren Buffet, and Sam Walton who started from humble beginnings and had a poor education yet grew to be some of the richest men the world has ever seen. Patrick Lencioni, author of The Five Dysfunctions of a Team, wrote ââ¬Å"Not education. Not experience. Not knowledge or intellectual horsepower. None of these serve as an adequate predictor as to why one person succeeds and another doesnââ¬â¢t. There is something else going on that society doesnââ¬â¢t seem to account for.â⬠1 It sparked the question, ââ¬Å"how could they be so successful while some of those graduating with the highest honors from the greatest universities would never make a name for themselves?â⬠Is IQ all it is made out to be? In reality, emotional intelligence is more critical to someoneââ¬â¢s success than IQ.The term ââ¬Å"emotional intelligenceâ⬠seems to first appear in a paper by Michael Beldoch in 1964. A few years later in 1983, the idea of multiple intelligences was introduced by Howard Gardner. This theory revolved around the idea that a human had more forms of intelligence than IQ. This theory included both intrapersonal intellig ence, which is, in other words, self-awareness and interpersonal intelligence, which is the ability to understand other individualsââ¬â¢ motives, interests, and desires. However, the idea that IQ was not the dominant intelligence didnââ¬â¢t gain traction until Daniel Goleman published his book Emotional Intelligence ââ¬â Why it can matter more than IQ in 1995. His book was a New York Times Best Seller for over a year and a half and is given credit for spreading this new found understanding of how we as humans work. Since then, more in-depth findings have been discovered and many more books have been written on these findings. Dr. Travis Bradberry, an intellect on the topic, argues in his book, Emotional Intelligence 2.0, that human behavior is made up of three main elements; IQ, EQ, and Personality. IQ is your capability or ability to learn and unless a traumatic brain injury occurs, it is fixed from birth. Because of this, your IQ typically will not change throughout your life and therefore you have very little influence over it. Personality defines the ââ¬Å"wayâ⬠you approach life and whether you are extroverted or introverted. Like IQ, personality is also relatively fixed, with most traits lasting your entire life. Many incorrectly believe that those with an extroverted personality have a higher EQ than introverts. This is not the case as EQ doesnââ¬â¢t influence what settings (alone or in a social group) you need to be in to ââ¬Å"rechargeâ⬠. In contrast, emotional intellige nce is the awareness of your emotions. Unlike the other three elements that make up human behavior, it is a skill that can be learned and improved. According to Dr. Bradberry, Emotional Intelligence is made up of four skills, split into two competences.Self-AwarenessSelf-awareness is ââ¬Å"your ability to accurately perceive your own emotions in the moment and understand your tendencies across situations.â⬠2 Increased self-awareness lessens the chance you might lose control of your emotions, or as Daniel Goleman put it in his book Emotional Intelligence; Why it can matter more than IQ, ââ¬Å"those moments of impassioned action that we later regret, once the dust has settled.â⬠3 Greater self-awareness also allows for a better understanding of what motivates you. Self-ManagementSelf-management is about controlling the emotions that you have now become aware of. Because of this, self-management depends entirely on understanding you; self-awareness. ââ¬Å"Anybody can become angry, that is easy; but to be angry with the right person, and to the right degree, and at the right time, and for the right purpose, and in the ri ght way, that is not within everybodys power, that is not easy.â⬠ââ¬â AristotleThatââ¬â¢s self-management. Social AwarenessSocial Awareness is simply the ability to understand otherââ¬â¢s emotions. It requires listening and observation

The United States Bureau Of Land Management - 971 Words
1 The U.S. Bureau of Land Management has stepped in to provide restorative practices upon 500,000 acres of heavily degraded public grasslands. This land is suffering from severe soil erosion as well as degradation due to overgrazing. The suppression of natural fires has caused shrubs and invasive weeds to encroach upon the grasslands. A full scale assessment will take place on this land before restoration efforts begin. The first thing that would need to be assessed is the soil, for it is eroding and holding little nutrient value. Samples would be taken of this soil from various parts of the grasslands including the eroded gullies. Each soil sample would be taken from at least 1 foot below the surface, to test for carbon richness below the topsoil. These would then be tested for texture, density, water retention, and chemical composition. Typically, powerful, healthy soil will contain amounts of both Nitrogen and Phosphorous, which are essential nutrients in sustainable plant growth. These samples would also be tested for any build-up of salts, something known as soil salinization. Unhealthy, salinized soil is created over years of over-hydrating and deep plowing. Excess water will suffocate root systems of once-healthy crops, and salinized soils will reduce crop output up to 20% (Withgott Brennan, 2011). The next assessment would be in the shrubs and invasive weed species on the land. Knowing the volume and location of these plants gives way to a better understanding ofShow MoreRelatedThe United States Federal Government875 Words à |à 4 Pagesexceedingly common throughout the United States.

What I will accomplish in This Course Free Essays
In this semester I would like to improve and develop my English writing and reading skills thru English 122. English 122 is not only just a requirement for transferring to four-year institution, but also a benefit for my whole life. My ultimate goal is going to medical school in order to become a doctor in the United States, I believe what I am learning in English 122 will make a significant contribution to my career Writing is not just simply communicating ideas or expressing thoughts on paper; writing skill is essential because a personââ¬â¢s intelligence and personality can be seen and judged thru the paper he or she writes. We will write a custom essay sample on What I will accomplish in This Course or any similar topic only for you Order Now Most importantly, good writing skill is essential to job interview. It is not avoidable that all the occupations need good writing to connect to employers and clients. If there is any misunderstanding between either clients or employers due to poor writing, itââ¬â¢s possible to loose jobs or contracts. As an international student, I never took neither English 116 nor English 118 during any semester in order to take English 122. In fact, the high school I graduated from had already prepared me to be eligible to take college level English class. One of the best parts of what I had learned in US high school is acknowledging grammar structure. When every time I take a look on my paper over and over, I can always tell where my grammar errors are and make corrections. For me personally, grammar is just made of a series of rules that I can easily memorize and go easy on it. On the other hand, I clearly feel myself lack of words through my essays, even though I am able to interpret things in simple ways. However, there is a big difference between college and high school writing and I believe that college level writing requires more sophisticated process and technique. If my essay is lack of words, specifically vocabulary and transition, the whole paper may not be interpreted that well. Another weakness I am very concerning is that I am not good at reasoning, a good paper must need to persuade readers to totally agree with my point of view. And I know my own explanation is not good enough to support my ideas. Applying to writing skills to real life, for instance, to medical school, neither scientific journals nor lab report can be presented verbally, both types of document must be written in sophisticate language. To let my professors and readers easily understand what I am trying to interpret, I definitely need a strong writing structure built up. And college level writing will build me the fundamental part in order to prepare for further education even job applications. Although I am in science major, I donââ¬â¢t want to think nor write as a scientist. Everything is not always static, so is the language. There might be a certain discipline in my paper but what I really want to learn from Mr. Leal is to think more critically, not simply just analyzing ideas of article, but also be able to stand on the other side to question the author.

Claiming the Right to Lie Essay Example For Students
Claiming the Right to Lie Essay Lies are told all over the place. In Right to Lie? Ã Robert Kasanoff claims that our right to lie should be protected by law because having a right to lie not only follows the traditions but also helps protect our reputation, relationships, and make our lives easier and more comfortable. Sometimes, I think that no one has ever lied as bad as I have. I dont intend to lie but my parents are very special to me and I dont want to hurt them so I end up lying. I have my own life away from them; I really wish sometimes that I could tell them but they think of me as their princess: so innocent, never told them a lie. Ive told my mum and dad so many lies. For example Ive told them Im doing schoolwork when in reality Im nowhere near schoolwork. I lie because I have a boyfriend, a boyfriend I know they wont approve of because they think Im young and I dont know what Im doing. I lie, so that I could spend time with my boyfriend, started off with small little white lies. There were those days I would tell my mum, Hey mum, Im going to stay after school today. I would meet with him at a laundry near my school and we would just hang out and play video games at the laundry. Later on we got closer and wanted to hang out somewhere different. From that moment I started growing my lies. I would tell my parents I was going for some tutoring and since my parents believe everything I tell them, they had no problem with me going. Once my mum would drop me off, I would walk over to the Rose Garden where I would meet up with my boyfriend from 4-6 p. m. We basically made our own life, we told each other everything, and we would go to the Science Center to eat and explore. Months went by and my lies continued. My relationships grew more and more to the point that I would go over to his house. He became part of my life; just as lying was part of me also. Those little white lies I would tell are now big elephant lies that I continue to tell and cant seem to stop. I do think that my lies save me from hurting my parents feelings, but then again once they find out I will have lost all of the confidence they had in me completely. I truly dont regret lying to them because all this time that Ive lied to them, I made my life with someone very special, someone that constantly reminds me of his love for me by telling me, Everything will be worth it in the end. Ã I know I shouldnt have lied to my parents in the first place, but I want them to at least feel for a while more until Im over age that Im the daughter that never did them wrong. Sometimes I feel they will understand me and tell me everythings going to be all right, but sadly my parents arent like that, theyre so last century. I love them but my lies will save me from losing their confidence and save them from getting hurt. Think about your lies before telling them, they can ruin your social and personal life. I do not yet know my destiny with all these lies Ive told, but I know for a fact that one writes their own destiny because the things you do make you who you are. Those little white lies we told as kids grow and now are massive lies that reflect on us.

The Impeachment Of Bill Clinton Essays - Lewinsky Scandal
The Impeachment Of Bill Clinton The Impeachment of Bill Clinton The government of the United States controls countless affairs in the world. They control everything from the currency to the court systems. Individuals are suppose to be able to trusting your government system, which has not been the case in many different circumstances. From Richard Nixon to the Whitewater scandal, the government has been everything but honest. Furthermore the President has not been honest either. He was the youngest governor of Arkansas and has been awarded with many different honors and still has misused his power. Bill Clinton has obstructed justice, carried on an affair while in presidency, and abused his power in office. He has also committed two counts of perjury and has lied under oath on more than one occasion. President Clinton should be impeached due to these countless acts of misconduct. Clinton has apologized many times for a variety of incidences that he has committed. A linguistics professor, Debroah Tannen told Time Magazine that ...men hardly ever apologize because doing so entails admitting fault and that shows weakness...(Carlson 44). Clinton has appeared on television many times admitting many things and apologizing for them. In the beginning of the Monica Lewinsky situation, Clinton said that he had not had a relationship with that woman, so ...why would Clinton now, after seven months of sustained lying, suddenly choose honestly? (Carlson 44). Many people say that it started when he was handed too much power at the early age of 32. Clinton started his life in the state of Arkansas and while he was still in high school, he had thoughts of being a doctor or a reporter. After meeting John F. Kennedy, his interest changed into politics and went on to college where he received his law degree in 1973. He married Hillary Rodham in 1975 and two years later, he became the youngest governor, in the nation, of Arkansas, at the age of 32. He was reelected more than three times for the state of Arkansas (DeGregorio 2). In 1992, William Clinton ran for President on the democratic ticket. His thoughts for the country were to create many jobs, lower taxes for the middle class, and help national health insurance. Although many people attacked him about an incident when he evaded military service and then tried to cover it up, he won the run and choose Senator Al Gore as his vice-president. He beat Republican Bush and Independent party Perot. President Clinton would be reelected again and he would have many issues while in his last term (DeGregorio 3). Clintons first problem occurred in 1994, when Paula Jones claimed that Bill Clinton propositioned her and exposed himself to her while he was governor of Arkansas. Clinton denied everything from the beginning. In 1997, Clinton offered $700,000 to settle the case, but Jones only wanted an apology. If Clinton did not do anything wrong, then why would he pay a hefty fine to dismiss the case? April first of this year, the Jones case was dropped, but was reopened in November. Jones came out with a recorded $800,000 settlement (Froomkin 1). The worries did not stop at the Jones case though. In 1995, Clinton allegedly started to have an affair with one of his interns, Monica Lewinsky who was 21 years old at the time. No one knew about these alleged affairs between Monica and the President, and after he stopped seeing her, is when Lewinsky took action. Clinton, just as in the Jones case, denied everything. People started to get suspicious about not one, but now two accusations against the President. Clinton said that he didnt have a relationship with her, which was correct, according to his definition of relationship. Clinton later changed his old story...to having an inappropriate relationship with her (Aubrey 3). While Lewinsky was gathering up evidence to support her case, Independent Council, Kenneth Starr, offered to help her. Lewinsky agreed and told Starr everything about the relationship. On September 9, 1998, Starr released his Starr Report that told about the Presidents affair. Before the release of the Report, Lacayo quoted Washington is bracing itself for the text unlike anything it has ever handled, with interludes that describe, in all too fascinating detail, ...engagement

Harriet Tubman Essay Example
Harriet Tubman Essay Example Harriet Tubman Essay Harriet Tubman Essay à ¡atherine Clintonââ¬â¢s biography ââ¬Å"Harriet Tubman: The Road to Freedomâ⬠is an interesting and comprehensive biography on Harriet Tubmanââ¬â¢s life. Catherine Clinton is a renowned historian with a special interest in black history. Many consider Harriet Tubman as the ââ¬Å"Black Mosesâ⬠of America and for good reason; she has lead hundreds of slaves to freedom, risking her own life for their welfare. This book is truly comprehensive and immersive and focuses on exposing the reality of Harriet Tubmanââ¬â¢s life. Most biographical narratives on Tubman have become predominantly focused on her myth, we all know her as the mastermind of the ââ¬Å"underground railroadâ⬠, but many aspects of her life have become forgotten. This narrative really focuses on Harriet Tubman, her trials and triumphs, and the truth about one of the most powerful women in American history. The reality of Harriet Tubmanââ¬â¢s life is an inspirational and motivating story, one that exceeds her mythological legacy. The purpose of this book was to recreate a historically accurate, and complete portrayal of Harriet Tubman. Clinton first introduces the world in which Harriet Tubman lived in. The book also delves into the topics of social history of American slavery and the antislavery movement, and how Harriet Tubman greatly fought for this cause. Clinton tells the story of Tubmanââ¬â¢s struggles and her life around the greater battle for emancipation that was occurring in America. Clinton provides a general overview of conditions for slaves along the Eastern shore; and how Harriet must have lived during her early life. : Harriet Tubman was very much an ordinary woman, with the normal complexities of ordinary life. However, her extraordinary accomplishments are how she is remembered today. However, Harriet Tubman endured travails that all human beings endure. However, what made Harriet Tubman so extraordinary was her strength and courage in facing the realities of life, and the dangers she exposed herself to be very real. Her character truly defines and speaks volumes about who she truly was, rather than her accomplishments. The primary subject of the book is Harriet Tubman herself. Tubman was born during the ââ¬Å"era of good feelingâ⬠, a historical period within American history of peace and prosperity. This of course did not apply to African Americans, whose lives were still controlled solely in the hands of their white owners. Clinton narrates Tubmanââ¬â¢s journey from being born a slave in Maryland to her daring escape to Canada, her daring journeys back to the United States and the already glorified endeavors of the Underground Railroad. Clinton also explains how Tubmanââ¬â¢s husband John Tubman had a substantial influence on Harriet. They were married as teens in Maryland, Clinton says that their early marriage was filled with ââ¬Å"happiness and repose, they loved each other tenderly and with great passionâ⬠. Little has been known about the relationship between these two. Clinton paints a picture of a happy couple torn apart through their conflicting moral values. John Tubman was content to live out his life on the farm. John felt that despite the conditions under which he lived, they were not as worse as comparable circumstances at other farms. His indecisiveness when it came to his personal freedom ultimately led him to refuse to run away with Harriet. Running away to Canada without John had a profound effect on her and was a turning point in her life. Harriet took a huge risk, one that took a lot of courage and conviction in her ideals to be able to leave her relationship. Harriet, the real human being, is a truly inspirational woman in history and is more than her legacy on the Underground Railroad. The biography really discerns the reality from myth of Harriet Tubman. The majority of the American public knows the story of Harriet Tubman, her courage in helping bring slaves into the north through a dangerous ââ¬Å"underground railroadâ⬠. The danger that she faced through this time of trial, her hunted status in the south, and her courage in standing up for African Americans as well as womenââ¬â¢s rights are well documented. However, Harriet Tubman was also a real person, and the personal story behind her accomplishments is far more important than her accomplishments. Tubman grew up much like any other slave. She did not receive divine aid, education, nor did she gain certain advantages over other slaves. The fact that she had a husband did not really separate her from others as well. The fact that Tubman wanted something more and acted upon her vision speaks volumes of her. Harriet Tubman was just as human as anyone else, but her special abilities and her courage arose whenever she needed to. The reason behind her dangerous trips into the heart of the South was that she strongly believed in her moral convictions, and that she put everything into her beliefs. She was an ordinary woman who rose up when called upon to do the extraordinary. The vast majority of people forget that she also lived a normal life, and that what she accomplished is really an inspiring story. Harriet Tubmanââ¬â¢s life is just as fascinating a story as the legacy she left behind. She is not a mythological figure of the African American freedom movement, but rather an ordinary individual who through her life experiences and moral convictions, transformed into a remarkable leader. A great lesson that can be drawn from Tubmanââ¬â¢s life is that complacency is the greatest obstacle to our moral convictions. It is all too easy to settle for what we have now, than to work for what we want later. Tubman reveals that the battle against complacency and the power to dream for a better tomorrow carries with it great hurdles and responsibilities. One has to rise above what one believes is incapable to accomplish their goals. Tubman applied this philosophy throughout her life. Tubman never saw what she did as extraordinary. What one accomplishes always seems incredible to others, but ordinary to those who went through every step of the way. Clinton, Catherine. Harriet Tubman: The Road to Freedom. First Edition. Boston: Little, Brown and Company, 2004.

Synthesis of Dibenzalacetone by Aldol Condensation of Benzaldehyde and Lab Report
Synthesis of Dibenzalacetone by Aldol Condensation of Benzaldehyde and Acetone - Lab Report Example Under basic conditions, the carbonyl group of acetone having an alpha hydrogen atom is converted to an enolate ion (Mc Murry, 1999, pp. 939). The enolate ion thus produced is a strong nucleophile and attacks the carbonyl group of the ââ¬Å"accepting partnerâ⬠, which in this case is benzaldehyde (Mc Murry, 1999, pp. 939). An alkoxide is formed as a result of this nucleophilic attack. The alkoxide then undergoes protonation by H2O, forming a ââ¬Å"neutral condensation productâ⬠, hydroxyketone. This undergoes dehydration in presence of NaOH, forming an enolate ion, hydroxyenolate, which then forms Benzalacetone by loss of a hydroxyl group. Benzalacetone also has alpha hydrogen, which again forms enolate ion under basic conditions, similar to the first step. This enolate nucleophilically attacks another Benzylaldehyde molecule. Subsequent reactions are similar to those already discussed, leading to the formation of dibenzalacetone, the final product. Thus, two molecules of be nzaldehyde and one molecule of acetone are required to form one molecule of dibenzalacetone.

The reaction was carried out in a conical vial containing a magnetic spinvane, according to the procedure specified in the SC214 practical manual, page 41. Filtration of the product was done using a Hirsch funnel, and the Craig tube method was used for purification and recrystalliz ation of the product as per the SC214 practical manual, page 42. Melting point and IR spectrum were also obtained for the characterization of the product. (iv) Results: The weight and yield of the product (dibenzalacetone) are calculated as follows: (1) Calculation of mass of the product: Weight of glass= 37.458 g Weight of glass along with Dibenzalacetone crystals= 37.502g Therefore, mass of Dibenzalacetone crystals= 37.502 ââ¬â 37.458 = 0.044g (2) Calculation of yield of the product: % Yield of Dibenzalacetone = Benzaldehyde is the limiting reactant in this experiment No. of moles of Dibenzalacetone= = = 0.001877 = 1.87 ? 10-4 moles No. of moles of Benzaldehyde= = = 0.000784 =7.84 ? 10-4 moles Since 2 benzaldehyde molecules are involved in each reaction, =7.84 ? 10-4/2 = 3.92 moles % yield of Dibenzalacetone= = = 0.477?100 = 47.7% Therefore, % yield of Dibenz
