Harvard Referencing

The Harvard referencing system It is important that you identify in your assessment when you are using the words or ideas of another author. The most accepted way of acknowledging the work of another author is to use a referencing system. It is important that you write down the details of your sources as you study. When taking notes, use a separate page for each new book, journal article, or electronic source. At the top of each page, clearly record the following information for future reference. For books, record: * The author’s or editor’s name (or names) * The year the book was published * The title of the book If it is an edition other than the first * The city the book was published in * The name of the publisher For journal articles record: * The author’s name or names * The year in which the journal was published * The title of the article * The title of the journal * The page number/s of the article in the journal * As much other information as you can fi nd about the journal, for example the volume and issue numbers For electronic resources, try to collect the information on the left if it is available, but also record: * The date you accessed the source * The electronic address or email The type of electronic resource (email, discussion forum, WWW page, etc) Whenever you use someone else’s ideas or words, you must put in a reference. Direct quotations – this is when you copy another author’s material word-for-word. You should show the reader that it is a direct quote by placing the material in inverted commas. Traditionally, double inverted commas have been used (â€Å") but it is now acceptable, and preferable to use single inverted commas (‘). Sometimes it is difficult to avoid the direct quotation as the author’s words may precisely describe the point you are trying to make.An example for direct quote from a book or journal article with one author: When organising our time, Adair (1988: 51) sta tes that ‘the centerpiece will tend to be goals and objectives’. OR When organising our time ‘the centrepiece will tend to be goals and objectives’ (Adair, 1988: 51). When you take another author’s ideas and put them into your own words. You are still copying someone else’s work, so you must reference it. You do not need to use inverted commas when you paraphrase, but you must clearly show the reader the original source of your information.All of the sources you refer to in the main body of your assignment need to be listed at the end of the assignment in a reference list. When creating a reference list, the sources should be listed alphabetically by author’s surname, but when the author is anonymous or unknown for any one source, insert that source in the alphabetical list using the title of the source instead of the author’s name. All sources should be listed together; there should not be separate lists for books versus journal articles versus electronic sources.The reference list should be on a separate page from the rest of the assignment and should be simply titled ‘References’ and the title should be in the same font and size as the other headings in your assignment. When you use the Harvard System, you are only usually required to produce a reference list. It is generally important in the text of an assignment to show the reader the author’s name, date of publication and page numbers of the original source. In the reference list, it is important that the author’s name, the year of publication, relevant titles, and other access information is faithfully reproduced.Department of Lifelong Learning: Study Skills Series http://education. exeter. ac. uk/dll/studyskills/harvard_referencing. htm Central Queensland University ESLS Unit (2001) Referencing: The Harvard referencing system, [Online], Available: http://www. cqu. edu. au/edserv/undegrad/clc/content/resources. htm [14 Aug 2001] Lewis, D.

Andromeda Was a Legendary Princess in Greek Mythology

Today we know of Andromeda as a galaxy, as the Andromeda Nebula, or as the Andromeda constellation located near the Pegasus constellation. There are also movies/TV programs bearing the name of this ancient princess. In the context of ancient history, she is a princess featured in the heroic Greek legends. Who Was Andromeda? Andromeda had the misfortune to be the daughter of the vain Cassiopeia, wife of King Cepheus of Ethiopia. As a result of Cassiopeias boast that she was as beautiful as the Nereids (sea nymphs), Poseidon (sea god) sent a great sea monster to ravage the coastline. An oracle told the king that the only way to get rid of the sea monster was to surrender his virgin daughter Andromeda to the sea monster; so he did, much as happened in the Roman story of Cupid and Psyche. King Cepheus chained Andromeda to a rock in the sea where the hero saw her. Perseus was still wearing the winged sandals of Hermes that he had used in the task of carefully decapitating Medusa while watching what he was doing only through a mirror. He asked what had happened to Andromeda, then when he heard, he promptly offered to rescue her by killing the sea monster, but on condition that her parents give her to him in marriage. With her safety uppermost in their minds, they instantly agreed. And so Perseus slew the monster, unchained the princess and brought Andromeda back to her many-relieved parents. The Wedding of Andromeda and Perseus Afterward, however, during wedding preparations, the happy celebrating proved premature. Andromedas fiance -- the one from before her enchaining, Phineus, showed up demanding his bride. Perseus argued that the surrender-to-her-death had invalidated the contract (and if he had really wanted her, why hadnt he slain the monster?). Then since his non-violent technique failed to persuade Phineus to gracefully bow out, Perseus pulled out the head of Medusa to show his rival. Perseus knew better than to watch what he was doing, but his rival didnt, and so, like many others, Phineus was instantly lithified. Perseus would go on to found Mycenae where Andromeda would be queen, but first, she gave birth to their first son Perses, who stayed behind to rule when his grandfather died. (Perses is considered the eponymous father of the Persians.) Perseus and Andromedas children were sons, Perses, Alcaeus, Sthenelus, Heleus, Mestor, Electryon, and a daughter, Gorgophone. After her death, Andromeda was placed among the stars as the Andromeda constellation. The monster who was sent to ravage Ethiopia was also turned into a constellation, Cetus. Pronunciation: Ã ¦n.dra.mÉ ª.dÉ™ Examples: Andromeda was the name of a TV series by Gene Roddenberry, starring Kevin Sorbo, the actor who played Hercules in the TV series. This is interesting because Andromeda was Hercules great grandmother.

The Ethical Dilemma Of Abc Essay - 2006 Words

FACTS Luke is an employee at ABC, and has been asked to work on a project that involves developing land that has been recently purchased to build an adult entertainment retail store. The land that ABC is purchasing is a plot of land located on the corner of the same neighborhood that Luke’s brother Owen lives in. The plans for the development of this land will remain private for one month. Once the plans are announced publicly, Luke knows that his brother’s property values will decrease significantly. Luke’s brother just received a modest offer on his home, but is thinking about declining the offer, as he has no reason to believe that the property value will not increase in the coming years. ISSUES Should Luke notify his brother of the plans, so that Owen can sell his home in advance of the publicly announced plans and subsequent property devaluation, or should Luke abide to his obligations to ABC by keeping the plans confidential until the official public announcement?

Schizophrenia in the Spotlight - 2236 Words

Schizophrenia in the Spotlight Many people have asked what schizophrenia is over the years. Schizophrenia is a serious disorder that makes simple everyday tasks hard to complete due to delusions, hallucinations, and disorganized speech. People with schizophrenia normally have a hard time forming relationships. Only around 1 percent of people will develop schizophrenia in their lifetime. Even though men and women’s onset of schizophrenia takes place at different ages, they are equally affected (Butcher, Hooley, Mineka, 2014).The treatment and prognosis on this disorder have greatly improved. Two of the main treatments for schizophrenia are pharmacotherapies and psychotherapies. There is still a lot that is unknown about schizophrenia. Research is being done on a regular basis to collect additional knowledge, to improve treatments, and increases peoples understanding on this disorder. There are a many known cases of schizophrenia, dating back to 1810, before it was even given its clinical name. John Haslam reported the first known case of schizophrenia in London, England in 1810. He explained the patient to have episodes of delusions, which is common in people with schizophrenia. (Butcher, Hooley, Mineka, 2014). In the 19th century, Emil Kraepelin, a German psychiatrist, was the one that discovered schizophrenia. At the time Kraepelin called it dementia praecox.

Comparison Claude Monet and Van Gogh Essay Example For Students

Comparison: Claude Monet and Van Gogh Essay This as not due to a lack in technique or training; this is a style that Monet acquired by using very dappled brushstrokes in his work. The individual brushstrokes portray the different shapes of each object, which enhances the composition of this piece. The overlapping of distinct brush strokes gives the piece depth and a lively quality. For example, the high grass is well depicted as blowing in the wind but this movement would not be as beautifully rendered if Monet didnt use dappled brushstrokes. The Path on the Island of Saint Martin, Bethel has a very rich use of color and rightness that bring a sense of clarity to the piece. Monet uses a variety of color in this piece but sticks to mostly earthy tones which gives the piece a harmonious feeling. Monet did not try to smooth away or diminish the appearance of their brush strokes, which was a popular technique during Impressionism. Another Impressionist technique that Monet used was capturing a fleeting moment. In Path on the Island of Saint Martin, Bethel Monet captures the fleeting effects of sunlight that happen throughout that day. Capturing these moments enhances the feeling of a certain impression of the scene. Rain by Vincent Van Gogh is oil painting that was created in 1889. Van Gogh was a famous artist during the Post-Impressionism time period and created artworks that had a strong emotional impact on viewers. Rain has several realistic depictions but stays true to Van Sagos personal experience during the rain storm. Rain has a sad emotional feeling to it, because of the muddy, dark, vivid colors that Van Gogh chose to use. Vincent Van Gogh manipulated many different color lattes in most of his works and he manipulates the colors in Rain by overlapping them to create new tones and shades. The color of the paint that Van Gogh uses perfectly depicts a rainy day; the viewer immediately gets a sense of a gloomy rainstorm when looking at the piece. Van Sagos line work in this piece is extraordinary and allows the viewer to experience the rainstorm first hand; his use of long and short diagonal strokes, which cover the entire forefront of the painting, effortlessly depict a rain storm. Van Gogh choose to use thick white strokes of paint to present the rain and it is rendered beautifully especially in contrast to the darker colors in the background. Van Gogh is able to capture the true essence of the rainstorm by painting the piece very blurry. He rejects the idea of the landscape in order for the viewer to focus more on the rain. Behind the blurriness of the piece the viewer can make out a small fence that Van Gogh painted into his piece. The fence is a little asymmetrical, but seems intentional in order to create a sense of depth and achieve Van Sagos perspective during the rainstorm. In comparison, it is apparent hat Post- Impressionism was highly influenced by Impressionism, and there are many similar techniques used in both pieces. Monet and Van Sagos paintings are both portraying an outdoor landscape of a wheat field, but are painted in many different and unique ways. Van Sagos looks as if it was painted wildly and quickly. Motets piece is clear that he took time to plan each paint stroke. Both oil paintings use earthy color tones but Van Sagos piece has a darker, muddy feel to it because of his technique of manipulating colors. Van Sagos work has a sense of looseness that test the mood and tone perfectly, while Motets work has a little bit more depiction to objects and the landscape. Both artist use oil paint and keep a thick texture of paint so both pieces have this feeling that they are somewhat Jumping out at you. Motets piece depicts the landscape quite clearly while Van Sagos piece is much more blurry and he denies much of the landscape. In Motets piece the trees, landscape, and wheat field are successfully depicted and you can even see some small details. In Van Sagos piece one is more focused on the rain than the blurred out landscape. .u29e11b3e2e7e3bad6233e19c89f30ef8 , .u29e11b3e2e7e3bad6233e19c89f30ef8 .postImageUrl , .u29e11b3e2e7e3bad6233e19c89f30ef8 .centered-text-area { min-height: 80px; position: relative; } .u29e11b3e2e7e3bad6233e19c89f30ef8 , .u29e11b3e2e7e3bad6233e19c89f30ef8:hover , .u29e11b3e2e7e3bad6233e19c89f30ef8:visited , .u29e11b3e2e7e3bad6233e19c89f30ef8:active { border:0!important; } .u29e11b3e2e7e3bad6233e19c89f30ef8 .clearfix:after { content: ""; display: table; clear: both; } .u29e11b3e2e7e3bad6233e19c89f30ef8 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u29e11b3e2e7e3bad6233e19c89f30ef8:active , .u29e11b3e2e7e3bad6233e19c89f30ef8:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u29e11b3e2e7e3bad6233e19c89f30ef8 .centered-text-area { width: 100%; position: relative ; } .u29e11b3e2e7e3bad6233e19c89f30ef8 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u29e11b3e2e7e3bad6233e19c89f30ef8 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u29e11b3e2e7e3bad6233e19c89f30ef8 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u29e11b3e2e7e3bad6233e19c89f30ef8:hover .ctaButton { background-color: #34495E!important; } .u29e11b3e2e7e3bad6233e19c89f30ef8 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u29e11b3e2e7e3bad6233e19c89f30ef8 .u29e11b3e2e7e3bad6233e19c89f30ef8-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u29e11b3e2e7e3bad6233e19c89f30ef8:after { content: ""; display: block; clear: both; } READ: A Comparison Of Coleridge's Rationalism To Wordsworth's Liberalism EssayBoth artists have great use of space that allows the viewer to gain a sense of perspective; Rain seems to be a perspective that was looking down on the wheat filed, while in Path on the Island of Saint Martin, Bethel the viewer is at ground level with the field. In closing, Monet and Van Gogh are very alike in the sense that they both enjoyed painting outdoor landscapes, but they are very different in the way they capture the scenes. Monet strove to capture the essence of a fleeting moment, such as light, while Van Gogh strove to capture the essence of a particular mood or emotion. These two different styles are clearly depicted when walking through the galleries at the Philadelphia Museum of Art. Claude Motets art work all give the viewer a sense of clarity with the use of earthy and warm colors that he uses to paint landscapes. Van Sagos art work often leaves one pondering of his exact emotive intentions were but for most, if not all, pieces the viewer is definitely able to feel an array of emotions while browsing through Van Sagos work.

Synthesis and Purification of Acetylsalicylic Acid Essays

Synthesis and Purification of Acetylsalicylic Acid (ASA or Aspirin) Introduction Salicylic acid is a phenol as well as a carboxylic acid. It can therefore undergo two different types of esterification reactions, creating an ester either with the hydroxyl or with the acid. In the presence of acetic anhydride, acetylsalicylic acid (aspirin or ASA) is formed. Correspondingly, an excess of methanol will form methyl salicylate, which is also an analgesic. In this experiment, we will use the first reaction in order to prepare aspirin. Salicylic acid will not react significantly with acetic acid to produce aspirin. Acetic acid anhydride, however, is more reactive than acetic acid because its acetate group (CH3CO2-1) is a much better leaving group than the HO-1 from the acetic acid. The reaction has one complication, however, in that an esterification can occur between the phenol and acid portion of adjacent salicylic acid molecules. Further, more molecules can bind to the remaining free substituents on these molecules to create a macromolecule, or polymer. The polymer is formed as a by-product. Acetylsalicylic acid will react with sodium bicarbonate to form a water- soluble sodium salt, whereas the polymer remains insoluble. This difference will be used to purify the aspirin product. The most likely impurity in the final product is salicylic acid, which can be either unconsumed reactant, or the result of hydrolysis of the aspirin product. Salicylic acid is removed during the purification steps as well. Salicylic acid, like most phenols, forms a highly colored complex with ferric chloride, and is easily detected. Aspirin does not form the colored complex because the hydroxyl has been acetylated. [pic] Background Reading McMurry, J., Organic Chemistry, 8th Ed., pp 830 and 835 (7th Ed, pp 802 & 806-7). J. Beran, Lab Manual for Principles of General Chemistry, 9th and 8th Ed., Experiment 19, pg 231. Key Words phenol, carboxylic acid, ester, acid anhydride, macromolecule Compound, Reaction, and Yield Data Provide systematic names for the reactant and product in the substance section. Provide tabulated and experimental melting ranges for product. Report mass and moles for the reactant and product, and calculate yield % on a molar basis. Mechanism The mechanism is called nucleophilic acyl substitution. It is similar, but not identical, to the hydrolysis on pg 830 in McMurry 8e. The electrophile is an acid anhydride, not an acid chloride. The entering nucleophile is salicylic acid (its phenol O), not water. On the resulting tetrahedral intermediate, the H from salicylic acid moves to the middle O on the anhydride. Finally, the leaving group is acetic acid, rather than chloride. No base is involved. Provide structures of all intermediates in your lab report. Substances 2.0 g salicylic acid 5.0 mL acetic anhydride 5 drops concentrated H2SO4 25 ml saturated NaHCO3(aq) 3.5 mL concentrated HCl Apparatus one 125-mL Erlenmeyer flask 70-mm filter paper and Buchner funnel 250-mL or 500-ml vacuum flask Procedure Part A: Synthesis 1. Weigh 2.0 g of salicylic acid crystals. Place in a 125-ml Erlenmeyer flask. 2. In a hood, slowly add 5.0 ml of acetic anhydride and 5 drops of concentrated sulfuric acid to the flask Caution - Concentrated H2SO4 solutions are corrosive and cause acid burns. Carboxylic acid anhydrides are corrosive and extremely hygroscopic. They will cause burns, and they have a strong vinegar-like odor. Use gloves and avoid all contact with skin, eyes, and nose.
