Derby Evening Telegraph Essay Example
Derby Evening Telegraph Essay Example Derby Evening Telegraph Essay Derby Evening Telegraph Essay Media is the plural of the word medium, which often refers to different ways of communicating with other people; if the target is a large number of people, then it is called mass media. There are many types of media, such as TV, radio, films, newspaper, Internet etc. The main purpose of media is to entertain; however they can also be used to persuade, inform, explain and advice. Media can be very powerful; therefore people are influenced and affected by them. The two articles we have looked at for analysis have a common theme both talks about the dangers and long-term effects of tanning.The first article is from The Big Issues and the second is from Derby Evening Telegraph. The Big Issue is a magazine sold on the streets of big cities; Derby Evening Telegraph is a local tabloid paper. Tanning has not always been very fashionable. In the Tudor times, untanned skin was considered to be a sign of wealth and status. People who were tanned were often labourers and peasants working outside on the farms. However in the nineteen twenties, when Coco Chanel, a top designer, returned from the Mediterranean with a tan, people thought that it was very attractive.Nevertheless not everybody could afford to travel abroad for a tan, it was only in the sixties, when package holidays came into place, going abroad was made possible. Nowadays, if people are tanned, it means that they have money to go on holiday abroad. The Big Issue, as mentioned before, is a magazine sold on the streets, and the profit goes to the homeless people. It was founded in nineteen ninety-four. The Derby Evening Telegraph is a local tabloid paper founded in eighteen seventy-nine with a circulation of approximately five and a half thousand.The two texts have been written with different intentions and they both have specific target audiences. The first text, Sun Vampires from The Big Issue, has been written to inform the readers of the dangers and long-term effects of tanning. Other purposes include: to ridicule the tanorexics, to advice people about the proper method of tanning and to warn those who are beginning to go on the sunbeds. The main target audience of this article is the younger generations of the society who are more likely to get addicted to tanning on sunbeds.Nevertheless to some extent, the authorial intent is to entertain and titillate leisurely readers who are looking for something to amuse the mind. In order to achieve the purpose and communicate the ideas to the readership, the writer uses vernacular language such as fork out, one hell of a habit and lets face it, and modern names, e. g. Peter Andre and Bros these techniques appeal greatly to the young people and therefore convey the message more effectively.The writer also grabs the attention of casual readers by using a light-hearted tone- as a result of this, the reader wouldnt be too shocked or frightened, thus willing to buy another copy of the magazine in the future. The second text, Face the fact the sun is a real danger, from Derby Evening Telegraph (DET), have similar purposes to the Sun Vampires: to inform, to advice and to warn. However, unlike Sun Vampires, this article concentrates more on one particular event, rather than the general overview of suntanning. This is because of the difference in the readerships.This article has been specifically written for the people of Derby. So by using a local story, the readers can relate themselves to it more, therefore are likely to be swayed by the contents of the text. An example of that is the inclusion of a local skin specialist nurse, i. e. Karen Elton; the readers might trust a local professional more than an external one because the chances are that they have heard of the expert somewhere before or have had contact with him or her. A possible age group of the target audience is middle-aged women.Younger girls might find it hard to relate to the older woman in the article because of the huge age difference. The words fact and danger suggest that the article is going to be serious, therefore it becomes less appealing to the younger girls. The citizens living in Derby, the main readership of D. E. T, are more likely to alert to the dangers of tanning and sense the urgency, because the story is happening very close to them. In order to effectively convey the messages many presentational devices are used in the two texts.The headline is bold print and immediately attracts casual browsers attention, hence making them interested in the article. The headline is positioned in a very eye-catching place: right at the top; the casual browsers is one of the target audiences and the headline would quickly meet their eyes. The strapline, which is just below the headline, gives more information about the headline, as if defining the words, Sun Vampires. However, it is not as important as the main headline, therefore it is in a slightly smaller font and less bold.The middle-sized picture of a young woman on a sunbed is a reflection of the headline. In the same way as the headline, the image shows contrast: the white sunbed Sun compares to the burnt skin Vampires. This helps the readers build much more vivid images of what Sun Vampires look like. Furthermore, a sunbed has connotations of a vampires coffin and the girl with blackened skin symbolises a vampire; this shocking image exaggerates the writers point and is almost an artistic translation of the headline. The illustration also assists to convey the message: it shows the long-term effects of tanning.This article is organised into columns, which makes it easier to read this is especially beneficial for the young readers that dont always have great concentration skills. Within the article, there are snippets of quotes from the text these are designed specifically for casual browsers who arent willing to read whole chunks of text to understand what the article is about. There isnt a caption to go with the illustration, however some may argue that the headline, Sun Vampires, in fact acts as a caption in someway.

For example, if an object is exactly a meter long and you measure it as 1.1 meters long, that is more accurate than if you measured it at 1.5 meters long. acid - There are several ways to define an acid, but they include any chemical that gives off protons or H in water. Acids have a pH less than 7. They turn the pH indicator phenolphthalein colorless and turn litmus paper red. acid anhydride - An acid anhydride is an oxide that forms an acid when it is reacted with water. For example, when SO3- is added to water, it becomes sulfuric acid, H2SO4. actual yield - The actual yield is the amount of product you actually obtain from a chemical reaction, as in the amount you can measure or weigh as opposed to a calculated value. addition reaction - An addition reaction is a chemical reaction in which atoms add to a carbon-carbon multiple bond. alcohol - An alcohol is any organic molecule that has an -OH group. aldehyde - An aldehyde is any organic molecule that has a -COH group. alkali metal s of alkali metals include lithium, sodium, and potassium. alkaline earth metal s of alkaline earth metals are magnesium and calcium. alkane - An alkane is an organic molecule that only contains single carbon-carbon bonds. alkene - An alkene is an organic molecule that contains at least one CC or carbon-carbon double bond. alkyne - An alkyne is an organic molecule that contains at least one carbon-carbon triple bond. allotrope - Allotropes are different forms of a phase of an element.

At the critical point, the liquid and vapor phases become indistinguishable from one another. crystal - A crystal is an ordered, repeating three-dimensional pattern of ions, atoms, or molecules. Most crystals are ionic solids, although other forms of crystals exist. delocalization - Delocalization is when electrons become free to move all over a molecule, such as when double bonds occur on adjacent atoms in a molecule. denature - There are two common meanings for this in chemistry. First, it can refer to any process used to make ethanol unfit for consumption (denatured alcohol). Second, denaturing can mean breaking down the three-dimensional structure of a molecule, such as a protein is denatured when exposed to heat. diffusion - Diffusion is the movement of particles from an area of higher concentration to one of lower concentration. dilution - Dilution is when aà solvent is added to a solution, making it less concentrated. dissociation - Dissociation is when a chemical reaction breaks a compound into two or more parts. For example, NaCl dissociates into Na and Cl- in water. double displacement reaction - A double displacement or double replacement reaction is when cations of two compounds switch places. effusion - Effusion is when a gas moves through an opening into a low-pressure container (e.g., is drawn by a vacuum). Effusion occurs more quickly than diffusion because additional molecules arent in the way. electrolysis - Electrolysis is using electricity to break the bonds in a compound to break it apart. electrolyte - An electrolyte is an ionic compound that dissolves in water to produce ions, which can conduct electricity. Strong electrolytes completely dissociate in water, while weak electrolytes only partially dissociate or break apart in water. enantiomers - Enantiomers are molecules that are non superimposable mirror images of each other. endothermic - Endothermic describes a process that absorbs heat. Endothermic reactions feel cold. endpoint - The endpoint is when a titration is stopped, typically because an indicator has changed color. The endpoint need not be the same as the equivalence point of a titration. energy level - An energy level is a possible value of energy that an electron can have in an atom. enthalpy - Enthalpy is a measure of the amount of energy in a system. entropy - Entropy is a measure of the disorder or randomness in a system. enzyme - An enzyme is a protein that acts as a catalyst in a biochemical reaction. equilibrium - Equilibrium occurs in reversible reactions when the forward rate of the reaction is the same as the reverse rate of the reaction. equivalence point - The equivalence point is when the solution in a titration is completely neutralized. It is not the same as the endpoint of a titration because the indicator may not change colors precisely when the solution is neutral. ester - An ester is an organic molecule with a R-CO-OR function group. excess reagent - Excess reagent is what you get when there is leftover reagent in a chemical reaction. excited state - An excited state is a higher energy state for an electron of an atom, ion, or molecule, compared with the energy of its ground state. exothermic - Exothermic describes a process that gives off heat. family - A family is a group of elements sharing similar properties. It is not necessarily the same thing as an element group. For example, the chalcogens or oxygen family consists of some different elements from the nonmetal group. Kelvin - Kelvin is a unit of temperature. A Kelvin is equal in size to a degree Celsius, although Kelvin starts from absolute zero. Add 273.15 to a Celsius temperature to get the Kelvin value. Kelvin is not reported with a à ° symbol. For example, you would simply write 300K not 300à °K. ketone - A ketone is a molecule that contains a R-CO-R functional group. An example of a common ketone is acetone (dimethyl ketone). kinetic energy - Kinetic energy is energy of motion. The more an object moves, the more kinetic energy it has. lanthanide contraction - The lanthanide contraction refers to the trend in which lanthanide atoms become smaller as you move left to right across the periodic table, even though they increase in atomic number. lattice energy - Lattice energy is the amount of energy released when one mole of a crystal forms from its gaseous ions. law of conservation of energy - The law of conservation of energy states the energy of the universe may change form, but its amount remains unchanged. ligand s of common ligands include water, carbon monoxide, and ammonia. mass - Mass is the amount of matter in a substance. It is commonly reported in units of grams. mole - Avogadros number (6.02 x 1023) of anything. node - A node is a location in an orbital with no probability of containing an electron. nucleon - A nucleon is a particle in the nucleus of an atom (proton or neutron). oxidation number The oxidation number is the apparent charge on an atom. For example, the oxidation number of an oxygen atom is -2. period - A period is a row (left to right) of the periodic table. precision - Precision is how repeatable a measurement is. More precise measurements are reported with more significant figures. pressure - Pressure is force per area. product - A product is something made as a result of a chemical reaction. quantum theory - Quantum theory is the description of energy levels and the predictions about the behavior of atoms at specific energy levels. radioactivity - Radioactivity occurs when the atomic nucleus is unstable and breaks apart, releasing energy or radiation. Raoults Law - Raoults Law states that the vapor pressure of a solution is directly proportional to the mole fraction of solvent. rate determining step - The rate determining step is the slowest step in any chemical reaction. rate law - A rate law is a mathematical expression relating the speed of a chemical reaction as a function of concentration. redox reaction - A redox reaction is a chemical reaction that involves oxidation and reduction. resonance structure - Resonance structures are the set of Lewis structures that can be drawn for a molecule when it has delocalized electrons. reversible reaction - A reversible reaction is a chemical reaction which can go both ways: reactants make products and products make reactants. RMS velocity - The RMS or root mean square velocity is the square root of the average of the squares of individual velocities of gas particles, which is a way of describing the average speed of gas particles. salt - An ionic compound formed from reacting an acid and a base. solute - The solute is the substance that gets dissolved in a solvent. Usually, it refers to a solid that is dissolved in a liquid. If you are mixing two liquids, the solute is the one that is present in a smaller amount. solvent - This is the liquid that dissolves a solute in solution. Technically, you can dissolve gases into liquids or into other gases, too. When making a solution where both substances are in the same phase (e.g., liquid-liquid), the solvent is the largest component of the solution. STP - STP means standard temperature and pressure, which is 273K and 1 atmosphere. strong acid - A strong acid is an acid that completely dissociates in water. An example of a strong acid is hydrochloric acid, HCl, which dissociates into H and Cl- in water. strong nuclear force - The strong nuclear force is the force that holds the protons and neutrons in an atomic nucleus together. sublimation - Sublimation is when a solid changes directly into a gas. At atmospheric pressure, dry ice or solid carbon dioxide goes directly into carbon dioxide vapor, never becoming liquid carbon dioxide. synthesis - Synthesis is making a larger molecule from two or more atoms or smaller molecules. system - A system includes everything you are evaluating in a situation. temperature - Temperature is a measure of the average kinetic energy of particles. theoretical yield - Theoretical yield is the amount of product which would result if a chemical reaction proceeded perfectly, to completion, with no loss. thermodynamics - Thermodynamics is the study of energy. titration - Titration is a procedure in which the concentration of an acid or base is determined by measuring how much base or acid is required to neutralize it. triple point - The triple point is the temperature and pressure at which the solid, liquid, and vapor phases of a substance exist in equilibrium. unit cell - A unit cell is the simplest repeating structure of a crystal. unsaturated - There are two common meanings for unsaturated in chemistry. The first refers to a chemical solution that does not contain all of the solute that can be dissolved in it. Unsaturated also refers to an organic compound which contains one or more double or triple carbon-carbon bonds. unshared electron pair - An unshared electron pair or lone pair refers to two electrons that arent participating in chemical bonding. valence electron - The valence electrons are the atoms outermost electrons. volatile - Volatile refers to a substance that has a high vapor pressure. VSEPR - VSEPR stands for Valence Shell Electron Pair Repulsion. This is a theory used that predicts molecular shapes based on the assumption that electrons stay as far as possible from each other.
