The Future of Women's Professional Sport - Essay Example The author of the essay "The Future of Women's Professional Sport" begins with the short introduction. He mentions that until recently, women’s professional sports were considered by many to be a novelty at best. Yet to assume men’s sports have been widely accepted throughout a long period of time would be incorrect. In 1950, only one professional sport, major league baseball, was dominant in America. Men’s professional football, basketball, and hockey organizations were, by comparison, niche businesses. It was only with the advent of television that interest in all men’s sports grew, for most at a fast pace starting in the 1960’s. To understand where the future of women’s professional sports might be headed, it is important to understand its past and its present in terms of the challenges that have been overcome as well as the problems that remain to be faced. Prior to the 1960’s, U.S. women lived in a society that discouraged girlsâ €™ participation in sporting activities and work outside the home. Because of this, few females at the time had aspirations of sport as a career path. The women who did pursue their athletic goals were therefore not as advanced as their male counterparts and remained unprepared to take advantage of the new media. Girls’ and women’s sports received a boost in 1972 when Title IX became law. To sum up the author says that excluding a few sports, such as tennis, ice skating and gymnastics, low salaries and unequal publicity are some of the problems that many professional female athletes still face.

Technology in the 20th Century Paper Essay Example for Free

Technology in the 20th Century Paper Essay There are many notable advances made in technology that took place during the twentieth century. The world gradually moved from the industrial age into the technology age during this era. Once technology took hold nothing could hold back the flood of its advancement and the innovation that grew from it. Of all of the important advancements three standouts that are intimately connected are the inventions of the radio, computers, and the internet. The radio could be said as the beginning of the information age and the sharing of information worldwide. The Radio The radio actually made it possible for the first time in humanity’s history for an audience to hear a person from many miles away. Before the television the radio was a way of gathering of people and families to share news and the storytelling that would have once perhaps been told around a communal fire. According to Kinsey, between the years of 1909 and 1927 Britain, America, Australia, South Africa, and the Netherlands were all broadcasting wirelessly through the radio (Kinsey, 2005). During this time radio broadcasts were all commercial, but that soon gave way to other kinds of broadcasts including music. Computers Another huge advancement created in the twentieth century is the computer. The computers that are enjoyed today hardly resemble the huge calculating machines that were created around the time of the second world war. In 1944 the very first electronic- mechanical computer called MARK 1 was created at Harvard. This machine was a massive calculator that was fifty one feet wide and eight feet tall (Chee, 1997). The beginning of the smaller computers that we know today started in 1959 when Honeywell developed the first computers that used transistors. These were followed by IBM who used integrated circuits. The very first personal computers were built in the 1970’s with the computers that are recognizable today starting in 1974 with the first Apple PC being created in 1977. Computer technology continues to grow and expand creating increasingly smaller and faster machines to keep up  with today’s fast paced life. The small seven or eight inch portable ipad has little resemb lance to its humongous forefather the MARK 1. The Internet The internet’s history is tied to the government and the Cold War in the 1960’s. The over 300,000 networks that cover much of the world actually saw its beginning as a system that was created to use satellites and radio transmissions to communicate for the military. The problem with the system was that there were not any networks to share the information. A system that solved this problem was created in 1982 and by 1993 the World Wide Web was popularized by nuclear physists that needed to communicate with each other (Chee, 1997). By the end of the 1980’s a number of mostly professional people were utilizing the Internet and email, but by the 1990’s the internet would see massive growth. By the end of 1999 the number of people using the internet was estimated to be 248 million (Cohen, 2011). The world has been made a smaller place because of the internet. People all around the earth can see events that are happening real time in places they may never physic ally get to visit. The many challenges that persist for humanity are made visible on a daily basis which in turn can be a way for people to see one another as extensions of themselves instead of enemies to be conquered. In conclusion, the social changes that arose from two world wars fertilized a society that was eager to learn and explore our world. While the society of the twentieth century struggled to gain realistic views of humanity, technological advancements like the radio, computers, and the Internet helped to create a much smaller world. The technology that is taken for granted in today’s society had very humble beginnings in the twentieth century. That technology has helped to close the gap and erase some of the imaginary lines that have historically separated the world’s population. These innovations have helped to heal the collective scars of decades of war, proving to humanity that we are alike in more ways than we could ever imagine. References: Chee, H. W. (1997, Mar 27).

Essay --

.. Manny Pacquiao is one of the most famous and highest paid boxer of our generation. He is a modern day Rocky Balboa except he is actually the real deal. It is only fitting that he represents some of the today’s top companies in their ads. Even more so for what I would consider the biggest company of them all, Nike. It is only fitting as that is what all of this generation’s sports stars do if they are elite athletes. The top portion has a black background with a beam of light coming in from the top as if it’s all eyes on him where you see that the beam is hitting a boxer grasping the ropes as he is on his knees. The ropes were colored red, white, and blue with a red turnbuckle. The boxer acts almost as if he is praying with an invisible â€Å"audience† is surrounded around him. He was ripped with muscles from head to toe showing how strong and well off this elite boxer is. He wore red Nike shoes and white trunks with a golden eagle design and â€Å"pacman† written on the sash of his trunks. The bottom of the ad reveals â€Å"MP† with a crown or sun on top of the â€Å"M†, the Nike logo, a quote that says â€Å"Give Us This Day† and the date â€Å"12.06.08.† The boxer was the only thing that really catches your attention. Unless you are an avid boxing fan you would not recognize who the man is, but thanks to his nickname on his trunks and the â€Å"MP†, almost any person could get the idea. It looks as if he is in prayer, but that is because he always prays before and after he fights. How he is situated in the picture with his arms and legs spread like they appear as if he is creating a picture of himself Jesus was when he was crucified. This could imply Pacquiao as being a savior and that he is going to save the hopes of all the ... ...also a disadvantage due to him not actually fighting in the Philippines When the fight was announced many said that de la Hoya would win because he was a much more experience boxer. This ad shows Pacquiao’s hidden fears because knew he couldn’t underestimate de la Hoya, so to bring â€Å"his heat† he wears Nike shoes. The advertisement reveals, even when you face a big threat, with Nike you will be unstoppable. An advertisement can mean or stand for anything, whether it is simple or complicated. It can have famous people, animals, be various colors or be black and white. The reason why one picture becomes an ad is because it represents something exactly what the company wants. And that is for you to want to buy and wear Nike products. This Nike ad with Manny Pacquiao is a very enjoyable ad that is a great example of such a simple picture being effective.

Stefan’s Diaries: Origins Chapter 17

September 8, 1864 She is not who she seems. Should I be surprised? Terrified? Hurt? It's as if everything I know, everything I've been taught, everything I've believed in my past seventeen years is wrong. I can still feel where she kissed me, where her fingers grasped my hands. I still yearn for her, and yet the voice of reason is screaming in my ears: You cannot love a vampire! If I had one of her daisies, I could pluck the leaves and let the flower choose for me. I love her †¦ I love her not †¦ I †¦ I love her. I do. No matter the consequences. Is this what following your heart is? I wish there was a map or a compass to help me find my way. But she has my heart, and that above all else is my North Star †¦ and that will have to be enough. After I slipped away from the carriage house back to my own chambers, I somehow managed to sleep for a few hours. When I awoke, I wondered if everything was all a dream. But then I shifted my head on the pillow and saw a neat puddle of dried, crimson blood and touched my fingers to my throat. I felt a wound there, and though it didn't hurt, it brought back the very real incidents of the previous evening. I felt exhausted and confused and exalted all at once. My limbs were enervated, my brain abuzz. It was as if I had a fever, but inside I felt a sort of calm I'd never felt before. I dressed for the day, taking extra care to wash the wound with a damp cloth and bandage it, then buttoned my linen shirt as high as it would go. I glanced at my reflection in the mirror. I tried to see if there was anything different, if there was some glint in my eye that acknowledged my newfound worldliness. But my face looked just as it had yesterday. I crept down the back stairs toward the study. Father's schedule was like clockwork, and he always spent the mornings surveying and visiting the fields with Robert. Once I closed myself in the cool, dark room, I ran my fingers along the leather-bound spines on each shelf, feeling comforted by their smoothness. I just hoped that somewhere, in the stacks and shelves of books on every subject, there would be a volume that would answer some of my questions. I remembered Katherine reading The Mysteries of Mystic Falls and noticed the volume was no longer in the study, or at least not in plain view. I walked aimlessly from shelf to shelf, for the first time feeling overwhelmed by the number of books in Father's study. Where could I possibly find information on vampires? Father had volumes of plays, fiction, atlases, and two full shelves of Bibles, some in English, some in Italian, and some in Latin. I traced my hands against the gilt- lettered, leather spines of each book, hoping that somehow I'd find something. Finally, my fingertips landed on a thin, tattered volume with Demonios written in flaking silver on the spine. Demonio †¦ demon †¦ This was what I was looking for. I opened the book, but it was written in an ancient Italian dialect that I couldn't make heads nor tails of, despite my extensive tutoring in Latin and Italian. Still, I carried the book with me to the club chair and settled in. Trying to decipher the book was an action I could understand, something easier than trying to eat breakfast while pretending everything was normal. I ran my fingers along the words, reading out loud as if I were a schoolboy, making sure I didn't miss a mention of the word vampiro. Finally, I found it, but the sentences surrounding it were nothing but gibberish to me. I sighed in frustration. Just then, the door to the study creaked open. â€Å"Who's there?† I called loudly. â€Å"Stefan!† My father's ruddy face registered surprise. â€Å"I was looking for you.† â€Å"Oh?† I asked, my hand flying to my neck, as if Father could see the bandage beneath the fabric. But all I felt was the smooth linen of my shirt. My secret was safe. Father looked at me strangely. He walked toward me, taking the book off my lap. â€Å"Y and I ou think alike,† he said, a strange smile curving onto his face. â€Å"We do?† My heart fluttered in my chest like a hummingbird's wings, and I was sure Father could hear my breath catching in short, shallow gasps in my throat. I felt sure he could read my thoughts, sure he knew about Katherine and me. And if he knew about Katherine, he'd kill her and †¦ I couldn't bear to think of the rest. Father smiled again. â€Å"We do. I know you took our conversation about vampires to heart, and I appreciate you taking this scourge seriously. Of course, I know you have your own motivations in avenging the death of your young Rosalyn,† Father said, making the sign of the cross over his chest. I stared at a thin spot on the Oriental rug, where the fabric was so faded, I could see the stained wooden floor below. I couldn't look up at Father and let my face betray my secret, betray Katherine's secret. â€Å"Be assured, son, that Rosalyn did not die in vain. She died for Mystic Falls, and she will be remembered as we rid our town of this curse. And you, of course, will be an integral part of the plan.† Father gestured toward the book I still held. â€Å"Unlike your good-for-nothing brother. What good is all his new military knowledge if he can't put it to use to defend his family, his land?† Father asked rhetorically. â€Å"Just today he went off on a ride with some of his soldier friends. Even after I told him I expected him here this morning to accompany us to our meeting at Jonathan's house.† But I wasn't paying attention anymore. All I cared about was that he didn't know about Katherine. My breathing slowed. â€Å"There wasn't very much information that I could understand in this book. I don't think it's very useful,† I said, as if all I'd been doing this morning was indulging in a scholarly interest in vampires. â€Å"That's just as well,† Father said dismissively, as he carelessly placed the book back on the shelf. â€Å"I feel that together we have a good store of knowledge.† â€Å"Together?† I parroted. Father waved his hand impatiently. â€Å"Y and I ou Father waved his hand impatiently. â€Å"Y and I ou and the Founders. We've set up a council to deal with this. We're heading to a meeting right now. Y ou're coming.† â€Å"I am?† I asked. Father glanced at me in annoyance. I knew I sounded like a simpleton, but there was simply too much information swimming in my mind to even begin to understand it all. â€Å"Y And I'm taking Cordelia as well. She has es. a good knowledge of herbs and demons. The meeting is at Jonathan Gilbert's house.† Father nodded, as if the subject was closed. I nodded as well, even though I was surprised. Jonathan Gilbert was a university teacher and sometimes inventor who Father not so privately called a crackpot. But now Father said his name with reverence. For the thousandth time that day, I realized this truly was a different world. â€Å"Alfred is hitching up the carriage, but I will drive it. Do not tell anyone where we're going. I've already sworn Cordelia to secrecy,† Father said as he strode out of the room. After a second, I followed him, but not before I slipped Demonios into my back pocket. I sat next to Father in the front seat of the carriage, while Cordelia sat in the back, hidden from sight lest she arouse suspicion. It was strange to be out in the morning, especially without a footman to drive us, and I caught the curious stares of Mr. Vickery as we passed by the Blue Ridge Estate next door. I waved, until I felt Father's hand on my arm, a subtle warning not to attract attention to ourselves. Father began talking once we entered the barren stretch of dirt road that separated the plantation road from town. â€Å"I don't understand your brother. Do you? What man doesn't respect his father? If I didn't know better, I'd think he was consorting with one of them,† Father said, spitting on the dirt road. â€Å"Why would you think that?† I asked uncomfortably, a trickle of sweat running down my spine. I ran my finger beneath my collar, recoiling when I felt the gauze bandage of my neck. It was damp, but from sweat or blood I could not tell. My thoughts were a tangle. Was I betraying Katherine by attending this meeting? Was I betraying Father by keeping Katherine's secret? Who was evil or good? Nothing seemed clear. â€Å"I think that because they have that kind of power,† Father said, using the whip on Blaze as if to prove the point. Blaze whinnied before shifting into a fast trot. I looked back at Cordelia, but she was impassively staring straight ahead. â€Å"They can take over a mind before a man realizes anything is amiss. They compel them to submit fully to their charms and whims. Just a glance can make a man do whatever a vampire desires. And by the time a man does know he's being controlled, it's too late.† â€Å"Really?† I asked skeptically. I thought back to last night. Had Katherine done that to me? But no. Even when I was frightened, I'd been myself. And all my feelings had been mine. Maybe vampires could do that, but Katherine certainly hadn't done it to me. Father chuckled. â€Å"Well, not all the time. One hopes that a man is strong enough to withstand that type of influence. And I certainly have raised my sons to be strong. Still, I wonder what could possibly have gotten into Damon's head.† â€Å"I'm sure he's fine,† I said, suddenly very nervous at the idea that Damon might have figured out Katherine's secret. â€Å"I think he's simply not sure what he wants.† â€Å"I don't care what he wants,† Father said. â€Å"What he needs to remember is that he's my son and I will not be disobeyed. These are dangerous times, much more so than Damon realizes. And he needs to understand that if he is not with us, people might construe that his sympathies lie elsewhere.† â€Å"I think he just doesn't believe in vampires,† I said, a sick feeling forming in the pit of my stomach. â€Å"Shhh!† Father whispered, waving his hand toward me to quiet me down. The horses were clip-clopping into town, just past the saloon, where Jeremiah Black was already nearly passed out by the door, a half bottle of whiskey at his feet. Somehow, I didn't think Jeremiah Black was listening or even seeing what was going on, but I nodded, pleased that the silence gave me a chance to sort through my thoughts. I glanced over to my right, where Pearl and her daughter were sitting on the iron bench outside the apothecary, fanning themselves. I waved to them, but, seeing Father's warning glance, thought better about calling out to say hello. I closed my mouth and sat silently until we reached the other end of town, where Jonathan Gilbert lived in an ill-kept mansion that had once belonged to his father. Father often made fun of the fact that the house was falling apart, but today he said nothing as Alfred opened the door of the carriage. â€Å"Cordelia,† Father called tersely, allowing her to walk up the rickety steps of the Gilbert mansion first as we followed suit. Before we could ring the bell, Jonathan himself opened the door. â€Å"Good to see you, Giuseppe, Stefan. And you must be Cordelia. I've heard much about your knowledge of native herbs,† he said, offering his hand to her. Jonathan led us through the labyrinthine hallways and toward a tiny door next to the grand staircase. Jonathan opened it and gestured for us to head inside. We took turns ducking down to enter a tunnel that was about ten feet long, with a flimsy ladder at the other end. Wordlessly we climbed the ladder and emerged into a tiny, windowless space that immediately made me feel claustrophobic. Two candles burned in tarnished candleholders on a water-stained table, and as my eyes adjusted to the dim light, I could make out Honoria Fells sitting gingerly on a rocker in the corner. Mayor Lockwood and Sheriff Forbes shared an old wooden bench. â€Å"Gentlemen,† Honoria said, standing up and welcoming us as if we were just stopping in for tea. â€Å"And I'm afraid I haven't made your acquaintance, Mrs†¦.† Honoria glanced suspiciously at Cordelia. â€Å"Cordelia,† Cordelia murmured, glancing from one face to another, as if this was the last place she wanted to be. My father coughed uncomfortably. â€Å"She treated Stefan during his spells after his †¦Ã¢â‚¬  â€Å"After his fiancï ¿ ½e got her throat ripped out?† Mayor Lockwood said gruffly. â€Å"Mayor!† Honoria said, clapping her hand to her mouth. As Jonathan ducked back out into the hall, I settled on a straight-backed chair as far away from the group as possible. I felt out of place, though probably not as out of place as Cordelia, who was now awkwardly sitting on a wooden chair next to Honoria's rocker. â€Å"Now, then!† Jonathan Gilbert said, coming back to the room, his arms laden with tools and papers and objects I couldn't even begin to identify. He sat on a moth-eaten velvet armchair at the head of the table and looked around. â€Å"Let's begin.† â€Å"Fire,† Father said simply. A shiver of fear ran up my spine. Fire was how Katherine's parents had perished. Was that because they were vampires, too? Had Katherine been the only one to escape? â€Å"Fire?† Mayor Lockwood repeated. â€Å"It's been recorded, many times in Italy, that fire kills them, as does beheading or a stake in the heart. And, of course, there are herbs that can protect us.† Father nodded to Cordelia. â€Å"Vervain,† Cordelia confirmed. â€Å"Vervain,† Honoria said dreamily. â€Å"How pretty.† Cordelia snorted. â€Å"It ain't nothing but a herb. But if you wear it, then you have protection from the devil. Some say it can also work a bit to nurse those who've been around them back to health. But it's poison to them devils you call vampires.† â€Å"I want some!† Honoria said greedily, holding out her hand eagerly. â€Å"I don't have any with me,† Cordelia said. â€Å"Y don't?† Father looked at her sharply. ou â€Å"It's all gone from the garden. I used it for Mr. Stefan's remedies; then when I went to pick it this morning, it was all gone. Was probably the children who took it,† Cordelia said indignantly, but she glanced straight at me. I looked away, reassuring myself that if she had known about Katherine's true nature, she would have told my father by now. â€Å"Well, then, where do I get some?† Honoria asked. â€Å"It's probably right under your nose,† Cordelia said. â€Å"What?† asked Honoria sharply, as if she'd been insulted. â€Å"It grows everywhere. Except our garden,† Cordelia said darkly. â€Å"Well,† Father said, glancing at the two women, anxious to diffuse the situation. â€Å"After this meeting, Cordelia may escort Miss Honoria to her garden to find vervain.† â€Å"Now, wait just a damn minute,† Mayor Lockwood said, pounding his beefy fist on the table. â€Å"Y lost me at the woman talk. Y mean to ou ou tell me that if I wear a lilac sprig, then the demons will leave me alone?† He snorted. â€Å"Vervain, not lilac,† Cordelia explained. â€Å"It keeps evil away.† â€Å"Y es,† Father said sagely. â€Å"And everyone in town must wear it. See to it, Mayor Lockwood. That way, not only will our citizens be protected, but anyone who does not wear it will be exposed as a vampire and can then be burned,† Father said, his voice so smooth and matter-of-fact that it took every ounce of self-control for me not to stand up, rush down the shaky ladder, find Katherine, and run away with her. But if I did that, and if Katherine was as dangerous as the Founders thought †¦ I felt like a trapped animal, unable to find any escape. Was I trapped with the enemy right now, or was the enemy back at Veritas? I knew that, beneath my shirt collar, the wound on my neck was beginning to ooze specks of blood, and it would only be a matter of time before they soaked through the fabric and stood out as a visible reminder of my betrayal. Mayor Lockwood shifted uneasily, causing the chair to creak. I jumped. â€Å"Now, if the herb works, that's one thing. But we're in the middle of a war. We've got a lot of Confederate government officials passing through Mystic Falls on their way to Richmond, and if word gets out that instead of aiding the cause we're fighting storybook creatures with flowers †¦Ã¢â‚¬  He shook his head. â€Å"We cannot issue an edict that everyone wear vervain.† â€Å"Oh, really? Then how do we know you're not a vampire?† Father demanded. â€Å"Father!† I interjected. Someone had to bring a voice of reason into the discussion. â€Å"Mayor Lockwood is right. We need to think calmly. Rationally.† â€Å"Y son has a good head on his shoulders,† our Mayor Lockwood said grudgingly. â€Å"A better head than yours,† Father mumbled. â€Å"Well †¦ we can discuss vervain later. Honoria, you'll be in charge of making sure that we have a ready supply, and we can strongly encourage those we love to wear it. But for now, I want to discuss other ways we can find the vampires that walk among us,† Jonathan Gilbert said excitedly, unfolding large sheets of paper onto the table. Mayor Lockwood put his bifocals on his nose and peered at the papers, which had complicated mechanical drawings on them. â€Å"This here looks like a compass,† Mayor Lockwood said finally, pointing to a complicated drawing. â€Å"It is! But instead of finding north, it finds vampires,† Jonathan said, barely containing his excitement. â€Å"I'm working on the prototype. It just needs a bit more fine-tuning. It's able to detect blood. The blood of others,† he said meaningfully. â€Å"Can I see that, Mr. Jonathan?† Cordelia asked. Jonathan looked up, surprised, but handed her the papers. She shook her head. â€Å"No,† she said. â€Å"The prototype.† â€Å"Oh, ah, well, it's very rough,† Jonathan said as he fumbled in his back pocket and pulled out a shiny metal object that looked more like a child's trinket than a tool for finding victims. Cordelia turned the compass slowly in her hands. â€Å"It works?† â€Å"Well †¦Ã¢â‚¬ Ã¢â‚¬â€œJonathan shrugged–â€Å"it will work.† â€Å"Here's what I propose,† Father said, leaning back on his chair. â€Å"We arm ourselves with vervain. We work day and night to get the compass to work. And we make a plan. We set up a siege, and by month's end our town will be clear.† Father crossed his arms in satisfaction. One by one, every member of the group, including Cordelia, nodded their heads. I shifted on the wooden chair, holding my hand against my neck. The attic was hot and sticky, and flies were buzzing in the rafters, as if it were the middle of July rather than the middle of September. I desperately needed a glass of water, and I felt like the room was going to collapse in on me. I needed to see Katherine again, to remind myself that she wasn't a monster. My breathing became shallow, and I felt that if I stayed here, I would say something I didn't mean. â€Å"I think I'm feeling faint,† I heard myself say, even though the words rang false even to my ears. Father looked at me sharply. I could tell he didn't believe me, but Honoria clucked out sympathetic noises. Father cleared his throat. â€Å"I'll see my boy out,† he announced to the room before following me down the rickety ladder. â€Å"Stefan,† Father said, grabbing my shoulder just as I opened the door that would lead back to a world I understood. â€Å"What?† I gasped. â€Å"Remember. Not a word of this to anyone. Even Damon. Not until he comes to his senses. Except I think his senses may be taken with our Katherine,† Father muttered, half to himself as he let go of my arm. I stiffened at the mention of Katherine's name, but when I turned around, Father's back was toward me as he headed into the house. I walked back through town, wishing I'd ridden Mezzanotte instead of coming in the carriage. Now I had no choice but to walk home. I turned to my left, deciding to cut through the forest. I simply couldn't interact with any more humans today.

Understanding Aerospace: How To Fly An Aircraft

1. The complicated task of piloting an aircraft can be broken into two broad categories. The first is keeping the aircraft flying. The second is arriving at a given destination. The second is always being effected by the first. Unlike a car, small deviation in course can over great distances cause the aircraft to arrive hundreds of miles from the target destination. To successfully accomplish the task, safe arrival, the larger tasks can be sub-divided into three categories. The first is the Procedural Tasks. These are the maintenance task that must be accomplished every time in a certain way at a certain time, i.e. take off and landing checklists. The next is Decision and Judgement Tasks. Problem solving is another way to look at it. The crew will react based on past experience to a given situation. The last is Communications and Resource Management. This is how the crew communicates with each other while problem solving, either poorly or well. 2. The pilot uses visual cues such as rate of flow of texture outward from or convergence of parallel linear features to visually fly the aircraft. Estimates of speed are derived from global optic flow (GOL). This is the rate that texture flows over the optical area. This can be effected by elevation, at higher elevations underestimation of true speed will occur. Approach path distortions occur when there is a slope before the landing strip or other visual features such as dwarfed trees. The human eye is not designed for conditions found in flight. Planes that are a collision course have no apparent movement to them. This takes the natural attraction to movement out of play. Because of the lack of visual stimulation the eye will focus only a few meters in front, so distant objects are unfocused. The scanning of instruments provides a source of input that allows the pilot to visualize the position of aircraft in flight. The novice pilot will scan all the instruments in a given pattern. While the experienced pilot will look at all the instrument that will give them feedback on the action that occurred. Of the main instrument the most useful is the attitude direction indicator (ADI). This is the instrument most referred and the one that most novice pilot will get fixated with. It is also the only one that resembles an aircraft and provides information in a format other than an analog circular dial. 3. Situational awareness is the ability to keep track of your surroundings and what they mean. Then predict how any change in them will effect your actions. This is measured the best, according to the author, by adding a task that can be performed well only when surrounding events are well know. The types of displays that best support awareness of position is best conveyed via 3-D. Speed of the aircraft is interpreted with a higher degree of accuracy in 2-D displays. Heads up displays (HUD) have been used for some time to give pilots information in away that allowed them to keep their attention outside of the cockpit. The thought is naturally to add more information to this already useful instrument. This would most likely result in the loss of information due to cluttering. Some information is lost in the HUD because of overlap with dominant terrain features. This might be avoided using a heads down display (HDD) type. They both have advantages and disadvantages. These may both be used to some extent with types of automation. The pilot may end up monitoring the flight only being called on when there is a problem. This results in the pilot being dissociated from the situation that they are to solve. Thus loosing time needed to solve the crisis trying to reorient themselves. A better way may be to use automation to provide information pertaining to the situation, i.e. filtering information.

Java Event Listeners Process User Activity in a GUI An event listener in Java is designed to process some kind of event  - it listens for an event, such as a users mouse click or a key press, and then it responds accordingly. An event listener must be connected to an event object that defines the event. For example, graphical components like a JButton ​or JTextField are known as  event sources. This means that they can generate events (called event objects),  such as providing a JButton for a user to click, or a JTextField in which a user can enter text. The event listeners job is to catch those events and do something with them. How Event Listeners Work Each event listener interface includes at least one method used by the equivalent event source. For this discussion, lets consider a mouse event, i.e. anytime a user clicks something with a mouse, represented by the Java class MouseEvent. To handle this type of event, you would first create a MouseListener class that implements the Java MouseListener interface. This interface has five methods; implement the one that relates to the type of mouse action you anticipate your user taking. These are: void mouseClicked(MouseEvent e)Invoked when the mouse button has been clicked (pressed and released) on a component.void mouseEntered(MouseEvent e)Invoked when the mouse enters a component.void mouseExited(MouseEvent e)Invoked when the mouse exits a component.void mousePressed(MouseEvent e)Invoked when a mouse button has been pressed on a component.void mouseReleased(MouseEvent e)Invoked when a mouse button has been released on a component As you can see, each method has a single event object parameter: the particular mouse event it is designed to handle. In your MouseListener class, you register to listen to any of these events so that you are informed when they occur. When the event fires (for example, the user clicks the mouse, as per the mouseClicked() method above), a relevant MouseEvent object representing that event is created and passed to the  MouseListener object registered to receive it.   Types of Event Listeners Event listeners are represented by different interfaces, each of which is designed to process an equivalent event. Note that event listeners are flexible in that a single listener can be registered to listen to multiple types of events. This means that, for a similar set of components that perform the same type of action, one event listener can handle all the events. Here are some of the most common types: ActionListener: Listens for an ActionEvent, i.e. when a graphical element is clicked such as a button or item in a list.ContainerListener: Listens for a ContainerEvent, which might occur if the user adds or removes an object from the interface.KeyListener: Listens for a KeyEvent in which the user presses, types or releases a key.WindowListener: Listens for a WindowEvent, for example, when a window is closed, activated or deactivated.MouseListener: Listens for a   MouseEvent, such as when a mouse is clicked or pressed.

How to Use a Highlighter to Improve Your Grades

How to Use a Highlighter to Improve Your Grades Highlighters are a modern invention. But marking up or annotating texts is as old as published books. Thats because the process of marking, highlighting, or annotating a text can help you to understand, remember, and make connections. The better you understand the text, the more effectively youll be able to use what youve read in arguments, debates, papers, or tests. Tips for Highlighting and Annotating Your Text Remember: the point of using a highlighter is to help you understand, remember, and make connections. That means youll need to actually think about what youre highlighting because you pull out the marker. Youll also, of course, need to be sure that the text youre highlighting belongs solely to you. If its a library book or a textbook youll be returning or reselling, pencil markings are a better choice. Highlighting willy-nilly is a waste of time. If you read a text and highlight everything that seems important, you’re not reading effectively. Everything in your text is important, or it would have been edited out before publication. The problem is that individual parts of your text are important for different reasons.You must determine what parts are important when it comes to the learning process, and determine those as worthy of highlighting. Without a plan for highlighting, you are simply colorizing your text. Before you start to read, remind yourself that some of the statements in your text will contain main points (facts/claims), and other statements will describe, define, or back up those main points with evidence. The first things you should highlight are the main points.Annotate while you highlight. Use a pencil or pen to make notes as you highlight. Why is this point important? Does it connect to another point in the text or to a related reading or lecture? Annotatio n will help you as you review your highlighted text and use it to write a paper or prepare for a test. Don’t highlight on the first reading. You should always read your school material at least twice. The first time you read, you will create a framework in your brain. The second time you read, you build upon this foundation and begin to really learn.Read your segment or chapter the first time to understand the basic message or concept. Pay close attention the titles and subtitles and read the segments without marking your pages at all.Highlight on the second reading. The second time you read your text, you should be prepared to identify the sentences that contain main points. You’ll realize that the main points are conveying the main points that support your titles and subtitles.Highlight other information in a different color. Now that you have identified and highlighted the main points, you can feel free to highlight other material, like lists of examples, dates, and other supporting information, but use a different color. Once you have highlighted the main points in a specific color and back-up information with another, you should use the highlighted words to create outlines or practice tests.
