  3. Mystery investigation

    I rush out of the bathroom & wrap my robe around me tightly. As beautiful as New York is, its mornings are brutally cold. I grab my trousers and try not to think about how creased they are. I want to wear my black shirt but suddenly remember shoving it in the washing machine, the previous night, trying to get the blood off. After all these years of being a detective, a witness of death & brutality, I still find blood a sight to cringe to. I put on my white shirt & look at myself in the mirror.

  4. America's Obsession

    Barbie from the beginning represented what the American teenager should be. The advertisements presented Barbie as a living teenager that most young girls would want to imitate. Barbie started off with a sideways glance, heavy makeup and numerous different hair colors, and eventually evolved into the blonde bombshell we all know today. Soon Ken, Barbie's "main squeeze" was introduced, later Midge, Barbie's best friend, then Skipper, Barbie's little sister. And many other different members of the Barbie family started to pop up. Soon there was a Barbie in every race imaginable.

  5. Most Wanted Hi, it's me! What, you don't know who I am? That's impossible

    I'm just sick of it. Do you have any idea, how long I've been doing this job? Already before mankind! The gods were so helpless without me. Even Athena needed some initial aid now and again. Always showing off with her wisdom, but do you think she could ever express her knowledge correctly? Not without me, I can tell you that. Well, one day we had a big fight, and she took revenge: there was this guy, who wanted to honor her with a song, but he just couldn't get into it. She told him then that he'd just have to get a kiss from me, and the ideas wouldn't stop flowing.

  6. On the run Sam and Paul could hear someone coming, it sounded like a wooing sound. They didn't know if it was the police or just a car, so they ran away really quietly so no-one could hear them.

    Then they both fell asleep because they were so exhausted. When they woke up they realised that they had travelled to a different part of the country which they were pleased about because they thought they would be safe there. There was only one problem; they had no money and no food. They were feeling very hungry and both of their bellies were rumbling. They started walking to try and find the nearest shops or supermarket. On the way they saw a sign saying "supermarket, one mile ahead". They started walking to the supermarket.

  7. Here is my 'Life in the Day of Jonathan Smithies'.My mum usually wakes me up at around 6:30 am because I have to walk tothe bus at 7:30. When I wake up I turn my fan

    My school uniform is already on my chair (I lay it out the previous night), I get dressed and washed and go downstairs to have my breakfast. I always eat the same breakfast for about six months and then I'll change and have something else. At the moment I'm having a hot cross bun with lots of strawberry jam and tropical juice. This is all part of having Obsessive Compulsive Disorder, the hot cross bun needs cutting into quarters, top and bottom; it needs to be on the same bread board if possible and the same amount of jam on each half.

  8. Can hard determinism be defended?

    Indeterminism on the other hand is merely determinism's denial. Indeterminism acknowledges the possibility of determinism to a certain degree but suggests that it is falsified through some uncaused random accordance's in the universe. In understanding or allowing ourselves a better perspective and grasp on things we need to consider the question of 'cause and effect' Let us consider, through the perspective of Hume, what is usually meant by saying, "A causes B?" Hume suggests that the most important perspective that needs to be considered is necessary connection. Necessary connection suggests that the common concept of causality is that the cause and the effect are necessarily connected- that is that if the cause occurs, the effect must occur as well; the effect cannot but occur.

  9. Using Counselling skills

    The fact that I can accept these previously hidden parts of Jillian's self (unconditional positive regard), helps her to accept them too. The counselling took place in Jillian's home. Jillian stated that she had been thinking of a subject to talk about and had decided that she would like to talk about the relationship she has with Tony a man who she calls her boyfriend but who is married to and lives with some one else and also has two children with the person he is married to.

  10. Creative Writing

    I made my way on foot in the direction of my jet. As I came to the stairs which would take me up to my jet there was a very beautiful air stewardess. She greeted me with a smile; she helped me with my things and guided me to my jet. She showed me to my seat as it was only me on the jet I asked the stewardess to put my things on the spare remaining seats, which would be no use to me.

  11. The Runaway

    Nothing to do, nothing to see, only animals for company. And she had the cheek to call me selfish! "You just can't bear to see me happy." Were the exact words she'd used. I bet she hadn't even noticed I'd gone; either that or she didn't care. He'd have only noticed when he realised his own personal punch bag was gone. Street lights flickered as they were been turned off. The gloomy light was lifting. I could only guess it must have been around 6am as I hadn't had time to get my watch, in my rushed escape. I looked round the bus stop, which was obviously once red, but now more brown than anything.

  12. Perception - the interpretation of information.

    This debate is called the nature - nurture debate. Within this essay the nature - nurture debate about perception will be discussed as will the conflicting theories, evidence and the opinions of the debate. Perception is the process by which we make sense of our sensations. The process of perception involves the brain decoding and making sense of information that it is reading. Sense organs operate through sensory receptor cells that receive external forms of energy and translate these in to neural impulse that are in the brain.

  13. Tracking my expenses over the course of a week.

    To make it worse, the week that I recorded my expenses, wasn't even too bad a week, work wise. These frequencies go up during midterms and finals. However, those figures wouldn't be an accurate representation of my spending habits. What motivated me to buy the cigarettes? That's a question I ask myself every day. Smoking is a habit I've been trying to kick since a year now. I've been smoking for three years now, and I am used to having that certain level of nicotine in my blood. It shows a weakness: knowing how much I spend on cigarettes, but buying them anyway, especially as they are not particularly healthy. I can safely say it has become an addiction.

  14. Problems that Ben faces in Deathwatch by Robb White.

    From there, Ben must climb the butte with his back and already flesh-torn knees. He goes about a foot at a time all the way to the top not looking up once because he feared the thought of self-defeat. Finally, Ben made it to the top of the butte where he eventually finds a tunnel with a small puddle of dirty water which keeps Ben alive, at least for longer than he expected. Another problem Ben must solve in Deathwatch is after he climbed up the butte. When he finally gets to the top of the butte, and gets a drink of water, he starts to realize how extremely hungry hi now is.

  15. The Mysterious Train.

    My shift was usually 9am to 6:30pm, but it would vary depending on how much clients I had to attend. Luckily, today I only had four clients, so I finished at what I call a breathtaking 3:00pm. I rushed to the train station to get the twenty past three train. I ran and ran I managed to get there for quarter past three , by now I was exhausted and out of breath as I pushed out my last bits of energy to proceed up the platform stairs.

  16. In 'A Question of Blood' by Ian Rankin Detective Inspector John Rebus has been asked to advise in a case which involves a former member of the SAS (Special Air Services) which Rebus has tried to join in the past.

    This also leaves Rebus's moves being watched. While this investigation has been started, another one is already underway. There has been a shooting at Port Edgar Public School in South Queensferry in which two school children were killed and one other injured by a man with a gun who shot himself after doing this atrocity. The gunman was later found to be a former member of the SAS and the officer in charge of the investigation just happened to know an officer in the force who may shed light on the investigation, the officer being John Rebus.

  17. Misspent Youth.

    As I have no device appropriate to store these invaluable clubs, I simply tied a rubber band around them and threw them into the back of my automobile, along with some dirty, unappreciated balls. The drive to the Golf Club was a little harsher than I thought it would be, as the previous night had been rather successful at my favorite watering hole, The Bay Hotel. Nevertheless I decided I partake in the cup, so I climbed behind the wheel of my car, gave an impeccably timed hiccup, put the key in my ignition and the music on low, and headed down the bitumen road to the Golf Course.

  19. Parachute Investigation.

    As the object is falling, the air friction pushes against it, and tries to slow it down. As it speeds up, the air friction gets greater and greater, until it reaches a point where the object cannot accelerate any more. This is called the objects "terminal velocity." Common sense tells us that the heavier an object the faster it will fall to the ground. If investigated you will find this to be untrue as all objects fall at a rate of 32 feet per second per second on earth.

  25. 2001 A space odyssey

    How could such a phenomenon occur? With such strong symbolic events and imagery in the opening seen it is hard to see them all as individual events, kubric uses these to tell the narrative of the story. The Sun is not just light, but heat (a desert). Making the Sun not necessarily good, the Sun is usually seen as positive in relation to dark, but not in a desert. This makes the sun a negative, with the use of water as a positive.

  26. Life In the Day of Ben Marshall

    It all flashes past without making much impression, until: "BEN! AREN'T YOU OUT OF THE HOUSE YET?" "NOT ACTUALLY, MOTHER!" "WELL BLOODY WELL HURRY UP AND GET OUT, NOW!" "FINE, I WILL. I MEAN, I AM!" Almost forgot. I put on a wheedling tone: "Oh, and by the way, can I have some extra money?" "OUT! NOW!" I guess not, then. As usual I have to run because I am always late. I am meant to be at Adam's house by a quarter to eight but ninety-nine times out of a hundred it's ten to.
