Educational Requirements for Post-Secodary Teaching 2019

Post-secondary teaching is a term that covers not only colleges and universities, but also technical and vocational schools. Training facilities like technical and vocational schools offer career specific courses of study that prepare students for jobs that dont necessarily require a four-year degree. Software and hardware specialists as we as welders, auto mechanics, cosmetologists and dental hygienists may have gone to such a school. The teaching staff at technical and vocational schools are normally required to have both degrees and experience in their industry. Sometimes only certification and experience is needed, such as in the field of cosmetology. In some cases, an associates degree is needed in addition to work experience and certification. In order to be eligible to teach in the computer field, however, a bachelors degree, and sometimes a masters degree, is required. Still, experience is needed. Community colleges or two year colleges require faculty to possess masters degrees. As time passes, more and more community colleges are seeking professors who have some experience in distance learning or other teaching experience. More than one masters degree is beneficial, as teaching more than one subject is possible. .ud07769ec341b1632439d34a2dc7bae3c { padding:0px; margin: 0; padding-top:1em!important; padding-bottom:1em!important; width:100%; display: block; font-weight:bold; background-color:#eaeaea; border:0!important; border-left:4px solid #34495E!important; box-shadow: 0 1px 2px rgba(0, 0, 0, 0.17); -moz-box-shadow: 0 1px 2px rgba(0, 0, 0, 0.17); -o-box-shadow: 0 1px 2px rgba(0, 0, 0, 0.17); -webkit-box-shadow: 0 1px 2px rgba(0, 0, 0, 0.17); text-decoration:none; } .ud07769ec341b1632439d34a2dc7bae3c:active, .ud07769ec341b1632439d34a2dc7bae3c:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; text-decoration:none; } .ud07769ec341b1632439d34a2dc7bae3c { transition: background-color 250ms; webkit-transition: background-color 250ms; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; } .ud07769ec341b1632439d34a2dc7bae3c .ctaText { font-weight:bold; color:inherit; text-decoration:none; font-size: 16px; } .ud07769ec341b1632439d34a2dc7bae3c .post Title { color:#000000; text-decoration: underline!important; font-size: 16px; } .ud07769ec341b1632439d34a2dc7bae3c:hover .postTitle { text-decoration: underline!important; } READ Research Shows Academic Performance Improves with AgeA majority of the faculty at four-year colleges and universities hold doctorates in their field. There are four classes of faculty in such a college: professor, associate professor, assistant professor and instructor. Often, graduate assistants hold teaching positions at universities. Sometimes four-year schools will hire people with masters degrees or doctoral candidates as part-time or temporary teachers to teach in the liberal arts category. Even so, members of the permanent faculty hold doctorate degrees. Faculty members at the university level are expected to participate in extra-curricular activities. They are also often required to become involved in research and to publish in academic publications. Many teachers on the college level also become accomplished authors. Professors that have outside academic interests and a certain amount of seniority have their graduate teaching assistants take care of the in-class sessions. Typically, these assistants are doctoral candidates. Doctorate degrees do not always lead to th teaching profession. There are many businesses who are seeking individuals with PhDs today. This is particularly true in the biotech and high tech industries. Those with PhDs who have started to teach on the college level have an increased opportunity in the business world today. .uf4f7f30e46f2e1fd6a624cb6f971901d { padding:0px; margin: 0; padding-top:1em!important; padding-bottom:1em!important; width:100%; display: block; font-weight:bold; background-color:#eaeaea; border:0!important; border-left:4px solid #34495E!important; box-shadow: 0 1px 2px rgba(0, 0, 0, 0.17); -moz-box-shadow: 0 1px 2px rgba(0, 0, 0, 0.17); -o-box-shadow: 0 1px 2px rgba(0, 0, 0, 0.17); -webkit-box-shadow: 0 1px 2px rgba(0, 0, 0, 0.17); text-decoration:none; } .uf4f7f30e46f2e1fd6a624cb6f971901d:active, .uf4f7f30e46f2e1fd6a624cb6f971901d:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; text-decoration:none; } .uf4f7f30e46f2e1fd6a624cb6f971901d { transition: background-color 250ms; webkit-transition: background-color 250ms; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; } .uf4f7f30e46f2e1fd6a624cb6f971901d .ctaText { font-weight:bold; color:inherit; text-decoration:none; font-size: 16px; } .uf4f7f30e46f2e1fd6a624cb6f971901d .post Title { color:#000000; text-decoration: underline!important; font-size: 16px; } .uf4f7f30e46f2e1fd6a624cb6f971901d:hover .postTitle { text-decoration: underline!important; } READ A Multitude of Computer Programming LanguagesRelated ArticlesUse the Internet to Attain a Masters Degree in TeachingFind Education and Teaching Degree ProgramsTechnology Universities and CollegesOnline Degree Opportunities For TeachersFind Vocational and Trade Online Degree ProgramsObtaining a Degree in Teaching

Theory As Framework For Research Example

Essays on Theory As Framework For Research Coursework Nursing Theory as Framework for Research It is unimaginable to think of research with no theory and concept in its framework. The conceptual framework consists of concepts that are sequentially designed. On the other hand, a theoretical framework offers a structure that serves as a reference basis for definitions of concepts, observations, interpretations, research design and generalization. Most of the studies published in the past 15 years are more conceptualized within nursing theories and concepts. However, some of the studies that center on comparison or of historical aspects of nursing lack theoretical frameworks. One such study is that of Bond et al. (2010) that offers a descriptive analysis of research articles published five years ago. Though this study seeks to determine the studies that use a theoretical framework and those that don’t, it lacks a theoretical framework itself. This study identified whether nursing researchers employed theory in their research and the kind of theory employed in the studies. A research study that lacks a theoretical framework lacks organization. McEwen and Wills (2014) denote that this is because theoretical structure of a study directs the researcher in interpreting the information obtained. This, therefore, implies that Bond et al. (2010) lacks a connection with the existing knowledge. Since the study lacks a theoretical and conceptual framework, the researchers cannot address theoretical assumptions. This implies that the study does not seek to respond to â€Å"how† and â€Å"why† (McEwen and Wills, 2014). Therefore, there is no intellectual transition that comes from recounting a phenomenon observed to take a broad view on numerous aspects of the phenomenon.ReferencesBond,  E.  A., Eshah,  N.  F., Bani-kahled,  M.  B., Hamad,  A.  O., Hashneh,  S.  H.

The Twilight Saga 4 Breaking Dawn 20. New Free Essays

Everything was so clear. Sharp. Defined. We will write a custom essay sample on The Twilight Saga 4: Breaking Dawn 20. New or any similar topic only for you Order Now The brilliant light overhead was still blinding-bright, and yet I could plainly see the glowing strands of the filaments inside the bulb. I could see each color of the rainbow in the white light, and, at the very edge of the spectrum, an eighth color I had no name for. Behind the light, I could distinguish the individual grains in the dark wood ceiling above. In front of it, I could see the dust motes in the air, the sides the light touched, and the dark sides, distinct and separate. They spun like little planets, moving around each other in a celestial dance. The dust was so beautiful that I inhaled in shock; the air whistled down my throat, swirling the motes into a vortex. The action felt wrong. I considered, and realized the problem was that there was no relief tied to the action. I didn’t need the air. My lungs weren’t waiting for it. They reacted indifferently to the influx. I did not need the air, but I liked it. In it, I could taste the room around me – taste the lovely dust motes, the mix of the stagnant air mingling with the flow of slightly cooler air from the open door. Taste a lush whiff of silk. Taste a faint hint of something warm and desirable, something that should be moist, but wasn’t†¦ That smell made my throat burn dryly, a faint echo of the venom burn, though the scent was tainted by the bite of chlorine and ammonia. And most of all, I could taste an almost-honey-lilac-and-sun-flavored scent that was the strongest thing, the closest thing to me. I heard the sound of the others, breathing again now that I did. Their breath mixed with the scent that was something just off honey and lilac and sunshine, bringing new flavors. Cinnamon, hyacinth, pear, seawater, rising bread, pine, vanilla, leather, apple, moss, lavender, chocolate†¦. I traded a dozen different comparisons in my mind, but none of them fit exactly. So sweet and pleasant. The TV downstairs had been muted, and I heard someone – Rosalie? – shift her weight on the first floor. I also heard a faint, thudding rhythm, with a voice shouting angrily to the beat. Rap music? I was mystified for a moment, and then the sound faded away like a car passing by with the windows rolled down. With a start, I realized that this could be exactly right. Could I hear all the way to the freeway? I didn’t realize someone was holding my hand until whoever it was squeezed it lightly. Like it had before to hide the pain, my body locked down again in surprise. This was not a touch I expected. The skin was perfectly smooth, but it was the wrong temperature. Not cold. After that first frozen second of shock, my body responded to the unfamiliar touch in a way that shocked me even more. Air hissed up my throat, spitting through my clenched teeth with a low, menacing sound like a swarm of bees. Before the sound was out, my muscles bunched and arched, twisting away from the unknown. I flipped off my back in a spin so fast it should have turned the room into an incomprehensible blur – but it did not. I saw every dust mote, every splinter in the wood-paneled walls, every loose thread in microscopic detail as my eyes whirled past them. So by the time I found myself crouched against the wall defensively – about a sixteenth of a second later – I already understood what had startled me, and that I had overreacted. Oh. Of course. Edward wouldn’t feel cold to me. We were the same temperature now. I held my pose for an eighth of a second longer, adjusting to the scene before me. Edward was leaning across the operating table that had been my pyre, his hand reached out toward me, his expression anxious. Edward’s face was the most important thing, but my peripheral vision catalogued everything else, just in case. Some instinct to defend had been triggered, and I automatically searched for any sign of danger. My vampire family waited cautiously against the far wall by the door, Emmett and Jasper in the front. Like there was danger. My nostrils flared, searching for the threat. I could smell nothing out of place. That faint scent of something delicious – but marred by harsh chemicals – tickled my throat again, setting it to aching and burning. Alice was peeking around Jasper’s elbow with a huge grin on her face; the light sparkled off her teeth, another eight-color rainbow. That grin reassured me and then put the pieces together. Jasper and Emmett were in the front to protect the others, as I had assumed. What I hadn’t grasped immediately was that was the danger. All this was a sideline. The greater part of my senses and my mind were still focused on Edward’s face. I had never seen it before this second. How many times had I stared at Edward and marveled over his beauty? How many hours – days, weeks – of my life had I spent dreaming about what I then deemed to be perfection? I thought I’d known his face better than my own. I’d thought this was the one sure physical thing in my whole world: the flawlessness of Edward’s face. I may as well have been blind. For the first time, with the dimming shadows and limiting weakness of humanity taken off my eyes, I saw his face. I gasped and then struggled with my vocabulary, unable to find the right words. I needed better words. At this point, the other part of my attention had ascertained that there was no danger here besides myself, and I automatically straightened out of my crouch; almost a whole second had passed since I’d been on the table. I was momentarily preoccupied by the way my body moved. The instant I’d considered standing erect, I was already straight. There was no brief fragment of time in which the action occurred; change was instantaneous, almost as if there was no movement at all. I continued to stare at Edward’s face, motionless again. He moved slowly around the table – each step taking nearly half a second, each step flowing sinuously like river water weaving over smooth stones – his hand still outstretched. I watched the grace of his advance, absorbing it with my new eyes. â€Å"Bella?† he asked in a low, calming tone, but the worry in his voice layered my name with tension. I could not answer immediately, lost as I was in the velvet folds of his voice. It was the most perfect symphony, a symphony in one instrument, an instrument more profound than any created by man___ â€Å"Bella, love? I’m sorry, I know it’s disorienting. But you’re all right. Everything is fine.† Everything? My mind spun out, spiraling back to my last human hour. Already, the memory seemed dim, like I was watching through a thick, dark veil – because my human eyes had been half blind. Everything had been so blurred. When he said everything was fine, did that include Renesmee? Where was she? With Rosalie? I tried to remember her face – I knew that she had been beautiful – but it was irritating to try to see through the human memories. Her face was shrouded in darkness, so poorly lit___ What about Jacob? Was he fine? Did my long-suffering best friend hate me now? Had he gone back to Sam’s pack? Seth and Leah, too? Were the Cullens safe, or had my transformation ignited the war with the pack? Did Edward’s blanket assurance cover all of that? Or was he just trying to calm me? And Charlie? What would I tell him now? He must have called while I was burning. What had they told him? What did he think had happened to me? As I deliberated for one small piece of a second over which question to ask first, Edward reached out tentatively and stroked his fingertips across my cheek. Smooth as satin, soft as a feather, and now exactly matched to the temperature of my skin. His touch seemed to sweep beneath the surface of my skin, right through the bones of my face. The feeling was tingly, electric – it jolted through my bones, down my spine, and trembled in my stomach. Wait,I thought as the trembling blossomed into a warmth, a yearning. Wasn’t I supposed to lose this? Wasn’t giving up this feeling a part of the bargain? I was a newborn vampire. The dry, scorching ache in my throat gave proof to that. And I knew what being a newborn entailed. Human emotions and longings would come back to me later in some form, but I’d accepted that I would not feel them in the beginning. Only thirst. That was the deal, the price. I’d agreed to pay it. But as Edward’s hand curled to the shape of my face like satin-covered steel, desire raced through my dried-out veins, singing from my scalp to my toes. He arched one perfect eyebrow, waiting for me to speak. I threw my arms around him. Again, it was like there was no movement. One moment I stood straight and still as a statue; in the same instant, he was in my arms. Warm – or at least, that was my perception. With the sweet, delicious scent that I’d never been able to really take in with my dull human senses, but that was one hundred percent Edward. I pressed my face into his smooth chest. And then he shifted his weight uncomfortably. Leaned away from my embrace. I stared up at his face, confused and frightened by the rejection. â€Å"Urn†¦ carefully, Bella. Ow.† I yanked my arms away, folding them behind my back as soon as I understood. I was too strong. â€Å"Oops,† I mouthed. He smiled the kind of smile that would have stopped my heart if it were still beating. â€Å"Don’t panic, love,† he said, lifting his hand to touch my lips, parted in horror. â€Å"You’re just a bit stronger than I am for the moment.† My eyebrows pushed together. I’d known this, too, but it felt more surreal than any other part of this ultimately surreal moment. I was stronger than Edward. I’d made him say ow. His hand stroked my cheek again, and I all but forgot my distress as another wave of desire rippled through my motionless body. These emotions were so much stronger than I was used to that it was hard to stick to one train of thought despite the extra room in my head. Each new sensation overwhelmed me. I remembered Edward saying once – his voice in my head a weak shadow compared to the crystal, musical clarity I was hearing now – that his kind, our kind, were easily distracted. I could see why. I made a concerted effort to focus. There was something I needed to say. The most important thing. Very carefully, so carefully that the movement was actually discernible, I brought my right arm out from behind my back and raised my hand to touch his cheek. I refused to let myself be sidetracked by the pearly color of my hand or by the smooth silk of his skin or by the charge that zinged in my fingertips. I stared into his eyes and heard my own voice for the first time. â€Å"I love you,† I said, but it sounded like singing. My voice rang and shimmered like a bell. His answering smile dazzled me more than it ever had when I was human; I could really see it now. â€Å"As I love you,† he told me. He took my face between his hands and leaned his face to mine – slow enough to remind me to be careful. He kissed me, soft as a whisper at first, and then suddenly stronger, fiercer. I tried to remember to be gentle with him, but it was hard work to remember anything in the onslaught of sensation, hard to hold on to any coherent thoughts. It was like he’d never kissed me – like this was our first kiss. And, in truth, he’d never kissed me this way before. It almost made me feel guilty. Surely I was in breach of the contract. I couldn’t be allowed to have this, too. Though I didn’t need oxygen, my breathing sped, raced as fast as it had when I was burning. This was a different kind of fire. Someone cleared his throat. Emmett. I recognized the deep sound at once, joking and annoyed at the same time. I’d forgotten we weren’t alone. And then I realized that the way I was curved around Edward now was not exactly polite for company. Embarrassed, I half-stepped away in another instantaneous movement. Edward chuckled and stepped with me, keeping his arms tight around my waist. His face was glowing – like a white flame burned from behind his diamond skin. I took an unnecessary breath to settle myself. How different this kissing was! I read his expression as I compared the indistinct human memories to this clear, intense feeling. He looked†¦ a little smug. â€Å"You’ve been holding out on me,† I accused in my singing voice, my eyes narrowing a tiny bit. He laughed, radiant with relief that it was all over – the fear, the pain, the uncertainties, the waiting, all of it behind us now. â€Å"It was sort of necessary at the time,† he reminded me. â€Å"Now it’s your turn to not break me.† He laughed again. I frowned as I considered that, and then Edward was not the only one laughing. Carlisle stepped around Emmett and walked toward me swiftly; his eyes were only slightly wary, but Jasper shadowed his footsteps. I’d never seen Carlisle’s face before either, not really. I had an odd urge to blink – like I was staring at the sun. â€Å"How do you feel, Bella?† Carlisle asked. I considered that for a sixty-fourth of a second. â€Å"Overwhelmed. There’s so much. †¦Ã¢â‚¬  I trailed off, listening to the bell-tone of my voice again. â€Å"Yes, it can be quite confusing.† I nodded one fast, jerky bob. â€Å"But I feel like me. Sort of. I didn’t expect that.† Edward’s arms squeezed lightly around my waist. â€Å"I told you so,† he whispered. â€Å"You are quite controlled,† Carlisle mused. â€Å"More so than expected, even with the time you had to prepare yourself mentally for this.† I thought about the wild mood swings, the difficulty concentrating, and whispered, â€Å"I’m not sure about that.† He nodded seriously, and then his jeweled eyes glittered with interest. â€Å"It seems like we did something right with the morphine this time. Tell me, what do you remember of the transformation process?† I hesitated, intensely aware of Edward’s breath brushing against my cheek, sending whispers of electricity through my skin. â€Å"Everything was†¦ very dim before. I remember the baby couldn’t breathe___† I looked at Edward, momentarily frightened by the memory. â€Å"Renesmee is healthy and well,† he promised, a gleam I’d never seen before in his eyes. He said her name with an understated fervor. A reverence. The way devout people talked about their gods. â€Å"What do you remember after that?† I focused on my poker face. I’d never been much of a liar. â€Å"It’s hard to remember. It was so dark before. And then†¦ I opened my eyes and I could see everything† â€Å"Amazing,† Carlisle breathed, his eyes alight. Chagrin washed through me, and I waited for the heat to burn in my cheeks and give me away. And then I remembered that I would never blush again. Maybe that would protect Edward from the truth. I’d have to find a way to tip off Carlisle, though. Someday. If he ever needed to create another vampire. That possibility seemed very unlikely, which made me feel better about lying. â€Å"I want you to think – to tell me everything you remember,† Carlisle pressed excitedly, and I couldn’t help the grimace that flashed across my face. I didn’t want to have to keep lying, because I might slip up. And I didn’t want to think about the burning. Unlike the human memories, that part was perfectly clear and I found I could remember it with far too much precision. â€Å"Oh, I’m so sorry, Bella,† Carlisle apologized immediately. â€Å"Of course your thirst must be very uncomfortable. This conversation can wait.† Until he’d mentioned it, the thirst actually wasn’t unmanageable. There was so much room in my head. A separate part of my brain was keeping tabs on the burn in my throat, almost like a reflex. The way my old brain had handled breathing and blinking. But Carlisle’s assumption brought the burn to the forefront of my mind. Suddenly, the dry ache was all I could think about, and the more I thought about it, the more it hurt. My hand flew up to cup my throat, like I could smother the flames from the outside. The skin of my neck was strange beneath my fingers. So smooth it was somehow soft, though it was hard as stone, too. Edward dropped his arms and took my other hand, tugging gently. â€Å"Let’s hunt, Bella.† My eyes opened wider and the pain of the thirst receded, shock taking its place. Me? Hunt? With Edward? But†¦ how? I didn’t know what to do. He read the alarm in my expression and smiled encouragingly. â€Å"It’s quite easy, love. Instinctual. Don’t worry, I’ll show you.† When I didn’t move, he grinned his crooked smile and raised his eyebrows. â€Å"I was under the impression that you’d always wanted to see me hunt.† I laughed in a short burst of humor (part of me listened in wonder to the pealing bell sound) as his words reminded me of cloudy human conversations. And then I took a whole second to run quickly through those first days with Edward – the true beginning of my life – in my head so that I would never forget them. I did not expect that it would be so uncomfortable to remember. Like trying to squint through muddy water. I knew from Rosalie’s experience that if I thought of my human memories enough, I would not lose them over time. I did not want to forget one minute I’d spent with Edward, even now, when eternity stretched in front of us. i would have to make sure those human memories were cemented into my infallible vampire mind. â€Å"Shall we?† Edward asked. He reached up to take the hand that was still at my neck. His fingers smoothed down the column of my throat. â€Å"I don’t want you to be hurting,† he added in a low murmur. Something I would not have been able to hear before. Tm fine,† I said out of lingering human habit. â€Å"Wait. First.† There was so much. I’d never gotten to my questions. There were more important things than the ache. It was Carlisle who spoke now. â€Å"Yes?† â€Å"I want to see her. Renesmee.† It was oddly difficult to say her name. My daughter, these words were even harder to think. It all seemed so distant. I tried to remember how I had felt three days ago, and automatically, my hands pulled free of Edward’s and dropped to my stomach. Flat. Empty. I clutched at the pale silk that covered my skin, panicking again, while an insignificant part of my mind noted that Alice must have dressed me. I knew there was nothing left inside me, and I faintly remembered the bloody removal scene, but the physical proof was still hard to process. All I knew was loving my little nudger inside of me. Outside of me, she seemed like something I must have imagined. A fading dream – a dream that was half nightmare. While I wrestled with my confusion, I saw Edward and Carlisle exchange a guarded glance. â€Å"What?† I demanded. â€Å"Bella,† Edward said soothingly. â€Å"That’s not really a good idea. She’s half human, love. Her heart beats, and blood runs in her veins. Until your thirst is positively under control†¦ You don’t want to put her in danger, do you?† I frowned. Of course I must not want that. Was I out of control? Confused, yes. Easily unfocused, yes. But dangerous? To her? My daughter? I couldn’t be positive that the answer was no. So I would have to be patient. That sounded difficult. Because until I saw her again, she wouldn’t be real. Just a fading dream†¦ of a stranger†¦ â€Å"Where is she?† I listened hard, and then I could hear the beating heart on the floor below me. I could hear more than one person breathing – quietly, like they were listening, too. There was also a fluttering sound, a thrumming, that I couldn’t place___ And the sound of the heartbeat was so moist and appealing, that my mouth started watering. So I would definitely have to learn how to hunt before I saw her. My stranger baby. â€Å"Is Rosalie with her?† â€Å"Yes,† Edward answered in a clipped tone, and I could see that something he’d thought of upset him. I’d thought he and Rose were over their differences. Had the animosity erupted again? Before I could ask, he pulled my hands away from my flat stomach, tugging gently again. â€Å"Wait,† I protested again, trying to focus. â€Å"What about Jacob? And Charlie? Tell me everything that I missed. How long was I†¦ unconscious?† Edward didn’t seem to notice my hesitation over the last word. Instead, he was exchanging another wary glance with Carlisle. â€Å"What’s wrong?† I whispered. â€Å"Nothing is wrong† Carlisle told me, emphasizing the last word in a strange way. â€Å"Nothing has changed much, actually – you were only unaware for just over two days. It was very fast, as these things go. Edward did an excellent job. Quite innovative – the venom injection straight to your heart was his idea.† He paused to smile proudly at his son and then sighed. â€Å"Jacob is still here, and Charlie still believes that you are sick. He thinks you’re in Atlanta right now, undergoing tests at the CDC. We gave him a bad number, and he’s frustrated. He’s been speaking to Esme.† â€Å"I should call him†¦,† I murmured to myself, but, listening to my own voice, I understood the new difficulties. He wouldn’t recognize this voice. It wouldn’t reassure him. And then the earlier surprise intruded. â€Å"Hold on – Jacob is still here?† Another glance between them. â€Å"Bella,† Edward said quickly. â€Å"There’s much to discuss, but we should take care of you first. You have to be in pain___† When he pointed that out, I remembered the burn in my throat and swallowed convulsively. â€Å"But Jacob – â€Å" â€Å"We have all the time in the world for explanations, love,† he reminded me gently. Of course. I could wait a little longer for the answer; it would be easier to listen when the fierce pain of the fiery thirst was no longer scattering my concentration. â€Å"Okay.† â€Å"Wait, wait, wait,† Alice trilled from the doorway. She danced across the room, dreamily graceful. As with Edward and Carlisle, I felt some shock as I really looked at her face for the first time. So lovely. â€Å"You promised I could be there the first time! What if you two run past something reflective?† â€Å"Alice – ,† Edward protested. â€Å"It will only take a second!† And with that, Alice darted from the room. Edward sighed. â€Å"What is she talking about?† But Alice was already back, carrying the huge, gilt-framed mirror from Rosalie’s room, which was nearly twice as tall as she was, and several times as wide. Jasper had been so still and silent that I’d taken no notice of him since he’d followed behind Carlisle. Now he moved again, to hover over Alice, his eyes locked on my expression. Because I was the danger here. I knew he would be tasting the mood around me, too, and so he must have felt my jolt of shock as I studied his face, looking at it closely for the first time. Through my sightless human eyes, the scars left from his former life with the newborn armies in the South had been mostly invisible. Only with a bright light to throw their slightly raised shapes into definition could I even make out their existence. Now that I could see, the scars were Jasper’s most dominant feature. It was hard to take my eyes off his ravaged neck and jaw – hard to believe that even a vampire could have survived so many sets of teeth ripping into his throat. Instinctively, I tensed to defend myself. Any vampire who saw Jasper would have had the same reaction. The scars were like a lighted billboard. Dangerous, they screamed. How many vampires had tried to kill Jasper? Hundreds? Thousands? The same number that had died in the attempt Jasper both saw and felt my assessment, my caution, and he smiled wryly. â€Å"Edward gave me grief for not getting you to a mirror before the wedding,† Alice said, pulling my attention away from her frightening lover. Tm not going to be chewed out again.† â€Å"Chewed out?† Edward asked skeptically, one eyebrow curving upward. â€Å"Maybe I’m overstating things,† she murmured absently as she turned the mirror to face me. â€Å"And maybe this has solely to do with your own voyeuristic gratification,† he countered. Alice winked at him. I was only aware of this exchange with the lesser part of my concentration. The greater part was riveted on the person in the mirror. My first reaction was an unthinking pleasure. The alien creature in the glass was indisputably beautiful, every bit as beautiful as Alice or Esme. She was fluid even in stillness, and her flawless face was pale as the moon against the frame of her dark, heavy hair. Her limbs were smooth and strong, skin glistening subtly, luminous as a pearl. My second reaction was horror. Who was she? At first glance, I couldn’t find my face anywhere in the smooth, perfect planes of her features. And her eyes! Though I’d known to expect them, her eyes still sent a thrill of terror through me. All the while I studied and reacted, her face was perfectly composed, a carving of a goddess, showing nothing of the turmoil roiling inside me. And then her full lips moved. â€Å"The eyes?† I whispered, unwilling to say my eyes. â€Å"How long? â€Å"They’ll darken up in a few months,† Edward said in a soft, comforting voice. â€Å"Animal blood dilutes the color more quickly than a diet of human blood. They’ll turn amber first, then gold.† My eyes would blaze like vicious red flames for months? â€Å"Months?† My voice was higher now, stressed. In the mirror, the perfect eyebrows lifted incredulously above her glowing crimson eyes – brighter than any I’d ever seen before. Jasper took a step forward, alarmed by the intensity of my sudden anxiety. He knew young vampires only too well; did this emotion presage some misstep on my part? No one answered my question. I looked away, to Edward and Alice. Both their eyes were slightly unfocused – reacting to Jasper’s unease. Listening to its cause, looking ahead to the immediate future. I took another deep, unnecessary breath. â€Å"No, I’m fine,† I promised them. My eyes flickered to the stranger in the mirror and back. â€Å"It’s just†¦ a lot to take in.† Jasper’s brow furrowed, highlighting the two scars over his left eye. â€Å"I don’t know,† Edward murmured. The woman in the mirror frowned. â€Å"What question did I miss?† Edward grinned. â€Å"Jasper wonders how you’re doing it.† â€Å"Doing what?† â€Å"Controlling your emotions, Bella,† Jasper answered. â€Å"I’ve never seen a newborn do that – stop an emotion in its tracks that way. You were upset, but when you saw our concern, you reined it in, regained power over yourself. I was prepared to help, but you didn’t need it.† â€Å"Is that wrong?† I asked. My body automatically froze as I waited for his verdict. â€Å"No,† he said, but his voice was unsure. Edward stroked his hand down my arm, as if encouraging me to thaw. â€Å"It’s very impressive, Bella, but we don’t understand it. We don’t know how long it can hold.† I considered that for a portion of a second. At any moment, would I snap? Turn into a monster? I couldn’t feel it coming on†¦. Maybe there was no way to anticipate such a thing. â€Å"But what do you think?† Alice asked, a little impatient now, pointing to the mirror. â€Å"I’m not sure,† I hedged, not wanting to admit how frightened I really was. I stared at the beautiful woman with the terrifying eyes, looking for pieces of me. There was something there in the shape of her lips – if you looked past the dizzying beauty, it was true that her upper lip was slightly out of balance, a bit too full to match the lower. Finding this familiar little flaw made me feel a tiny bit better. Maybe the rest of me was in there, too. I raised my hand experimentally, and the woman in the mirror copied the movement, touching her face, too. Her crimson eyes watched me warily. Edward sighed. I turned away from her to look at him, raising one eyebrow. â€Å"Disappointed?† I asked, my ringing voice impassive. He laughed. â€Å"Yes,† he admitted. I felt the shock break through the composed mask on my face, followed instantly by the hurt. Alice snarled. Jasper leaned forward again, waiting for me to snap. But Edward ignored them and wrapped his arms tightly around my newly frozen form, pressing his lips against my cheek. â€Å"I was rather hoping that I’d be able to hear your mind, now that it is more similar to my own,† he murmured. â€Å"And here I am, as frustrated as ever, wondering what could possibly be going on inside your head.† I felt better at once. â€Å"Oh well,† I said lightly, relieved that my thoughts were still my own. â€Å"I guess my brain will never work right. At least I’m pretty.† It was becoming easier to joke with him as I adjusted, to think in straight lines. To be myself. Edward growled in my ear. â€Å"Bella, you have never been merely pretty.† Then his face pulled away from mine, and he sighed. â€Å"All right, all right,† he said to someone. â€Å"What?† I asked. â€Å"You’re making Jasper more edgy by the second. He may relax a little when you’ve hunted.† I looked at Jasper’s worried expression and nodded. I didn’t want to snap here, if that was coming. Better to be surrounded by trees than family. â€Å"Okay. Let’s hunt,† I agreed, a thrill of nerves and anticipation making my stomach quiver. I unwrapped Edward’s arms from around me, keeping one of his hands, and turned my back on the strange and beautiful woman in the mirror. How to cite The Twilight Saga 4: Breaking Dawn 20.

Civil Engineering Research Association Situational Judgment

Question: Describe about the Civil Engineering Research Association for Situational Judgment. Answer: Selection methods and minority representation in CERA Civil Engineering Research Association (CERA) is an organization that is associated with the infrastructural programs for present better infrastructural projects. Henry et al. (2014) depicts that this association values the betterment of the society and thus researches on the longevity of the architectural project they accomplished. Moreover, they have also taken initiatives for increasing the representation of Aboriginal people in its workforce. The concerned organization has adopted two methods for selecting their candidates- Situational Judgment Tests (SJT) and Online Recruitment procedure. In this assignment, the job category that is taken into consideration for this assignment is Geotechnical engineering, where the professionals investigate the engineering behavior of earth materials. Situational Judgment Tests (SJT) Weekley and Ployhart (2013) defines that Human resources selection techniques vary with the organizational culture and its demand for achieving the goal thus selecting effective working personnel requires a wise hiring decision. In Situational Judgment Tests (SJT), CERA asks the candidates to depict their opinion on how they will respond to some formulated hypothetical situations. Whelpley et al. (2015) illustrated that for instance, the candidates is asked to represent the best knowledge of soil mechanics and rock mechanics regarding with a construction project in Queensland. Sharma et al. (2013) further affirms that HR of the concerned organization will be able to assess their ability to investigate subsurface conditions and materials along with the physical/mechanical and chemical properties of these materials. Recruiting suitable indigenous people for this job designation will be beneficial for CERA as they can communicate with the colleagues efficiently and work together for achieving the organizational objectives. These aboriginal people do not have to learn about the culture of the nation and the organization. Henry et al. (2014) also stated that the education provides to every nation and the level of the concept taught to them varies with the country. Thus, in the Situational Judgment Tests, these non-aboriginal candidates may not fulfill the expectation of the human resources, who are looking for the best candidates for their civil engineering association; thus, the recruitment of the aboriginal employee can be advantageous for the organization. For instance, if the CERAs human resources ask them to depict their opinion on the fault distribution andbedrockproperties to gain an understanding of the area. It is important to assess their ability about the risks of the environment like- earthquakes, soil liquefaction, rock falls,landslides andsinkholes so that the infrastructural projects can be accomplished hassle free. In addition to that, Slaughter et al. (2014) states that in this recruiting process, it is effortless for meeting compliance and customers requirements as the native employee can effectively communicate with the locals about their opinion and demands. In this way, candidates can better define their perception to the human resources and it will be beneficial for shaping public and industry policy. Online Recruitment Procedure The other recruitment procedure is the online recruitment procedure, where job seekersgo through the applications or curriculum vitae (CV), through e-mail or internet protocol. Bauermeister et al. (2012) mentioned that CERA implemented this method of recruitment so that they can evaluate the candidates knowledge and friendliness towards the modern digital technology. However, Brandon et al. (2013) criticizes the recruitment procedure by stating that some of the suitable candidates are rejected who do not have much interaction with the internet and modern technology. Moreover, Gliddon et al. (2015) also affirms that as the network availability is not the same due to which some suitable candidate do not apply their CV to the organization and the organization hence miss out that candidate. In this case, recruitment of the aboriginal candidates will be beneficial, as they know the organizational digital technology. RoyChowdhury and Srimannarayana (2013) also depicts that even though they are not aware of the technology, training can be provided to them effortlessly. Recruiting through online, however, reduces the time spend for an interview but it requires extra expenses like the telephone charges, network charges and some amount to intermediary associations. Thus, spending those monetary amounts in the training procedure will be more effective for achieving organizational goals with the help of the Aboriginal employee. One of the crucial points that Glover et al. (2015) demonstrates that the recruiting indigenous people will it only useful for the organization but it will also improve the nations economic condition as it reduces the unemployment rate and help in expanding the talent pool among the working personnel. Slaughter et al. (2014) also, depict that the Aboriginal People are an obvious source of potential workers and they have the good business sense of the organization from the federal government perspective.

What Would I Tell the Founding Fathers free essay sample

If you had the opportunity to talk to the Founding Fathers what would you ask them? If had the chance I would discuss three things with the Founding Fathers I would ask about how their political experience was, religion, and their legacy. Just to tell you a little about the Founding Fathers, they were political leaders and statesmen. They participated in the American Revolution by signing the Declaration of Independence. I wonder how their experience was in the political stand .The framers of the Constitution had extensive political experience. By 1787, four-fifths (41 people), Were or had been members Of the Continental Congress. Nearly all of the 55 delegates had experience in colonial and state government, and most of them had held county and local offices. The ones who lacked congressional experience were Bassett, Blair, Barely, Broom, Davie, Dayton, Alexander Martin, Luther Martin, Mason, McClure, Paterson, Charles Pinkeye, Strong, Washington and Yates.

Want Answers Top 20 Current Trends in Resumes and Job Search

Want Answers Top 20 Current Trends in Resumes and Job Search What’s the â€Å"right† way to write a resume or conduct a job search? People ask me questions all the time about how many pages a resume should be; whether to include an Objective statement; what the value is of a web portfolio; etc. The fact is, there is no clear cut answer to many of these questions, and the answers change year by year, even day by day. They certainly can change depending on who you are, what industry you’re in, and what your experience level is. Ask the Experts Given that resume writing and job search strategies are constantly changing, I feel fortunate that there is a coalition of experts who spend a lot of time thinking about these issues, and even more fortunate that they share their wisdom each year. On December 30, 2010, a consortium of 156 career experts from the U.S., Canada and the U.K. met to brainstorm about career and employment issues. They published their findings on March 14, 2011 in Findings of 2010 Global Career Brainstorming Day: Trends for the Now, the New the Next in Careers. As my readers, you are privy to the valuable findings of this group of Career Thought Leaders. The latest trends in resume writing and job search strategies include: Your Google results are the new resume. Build a strong online presence so you look good when those results come up. And monitor your Google results routinely in case of anything fishy! Keep it short. Three-page resumes are discouraged, regardless of your experience level. Use â€Å"extras† or addenda if necessary for publications, technology qualifications, consulting experience, etc. Culture fit is more important than your skill set. Companies hire people, not resumes. Web portfolios are not as useful as you might think in most industries. Brand yourself! Keep your brand consistent throughout your job search documents. DO use a Core Competencies or Key Strengths section. DO put a testimonial or two on your resume. DO use tasteful graphic touches, including borders, text boxes or graphs when appropriate. Show the company what YOU can do for THEM. Write resume bullets that clearly show the problem you solved and how you solved it. If possible, write your intended job title instead of â€Å"Summary of Qualifications† above your summary. This structure makes your objective clear, and allows you to write a summary of your offerings instead of an objective. DO send paper resumes! They will make you stand out from the crowd. DO send a cover letter. Do not expect that it will be read. However, in some cases it is read first, so assume it will be read. E-cover letters (in the body of an email) can be short and sweet. Have a bio available in addition to a resume as an alternative introduction to a resume. Format your resume in Microsoft Word .doc format. Have a plain text resume available as well. Use Twitres (www.twitres.com) to display your resume on Twitter. Use Box.net to display your resume on LinkedIn (Box.net is my personal tip) Networking is still the absolute best way to get a job. Job boards just are not an effective tool for job search, although you should use them as part of your strategy. Only 13.2% of external hires in Fortune 500 companies came from job boards, whereas 26.7% came from referrals and 22.3% came from employer career sites. Overall, somewhere between 65-95% of all new hires come as a result of networking. That’s a pretty staggering statistic! Social networking an essential job search strategy, and LinkedIn tops the chart. 80% of recruiters use social media to recruit candidates. You absolutely MUST have a strong presence on LinkedIn, â€Å"the #1 online networking platform for job seekers† according to the report. Clear skeletons out of your closet if you can. With so many candidates vying for each open position, any red flags mean your application is put in the â€Å"no†pile. Employers will go back 20-30 years to make sure your record is clean. Become savvy with virtual technology. You might be required to attend a virtual interview, or you might choose to create a web-based resume or portfolio to get some extra notice. Need help to manage it all? Many job seekers are hiring virtual assistants just to keep up with it all! If you want to read more detail about these top 20 points, please go to the full article, Findings of 2010 Global Career Brainstorming Day: Trends for the Now, the New the Next in Careers.

British Airways Research Paper Example | Topics and Well Written Essays - 2000 words

British Airways - Research Paper Example Three countries have been selected as the most appropriate targets for such initiative: Mexico, Brazil and Ukraine. Each of these countries can offer different benefits in regard to the firm’s particular plan. Mexico seems to meet all criteria as a target country for outsourcing activities. Brazil and Ukraine can also respond to the firm’s specific needs under the terms that appropriate arrangements of cooperation are made. The various aspects of such plan are presented below emphasizing on both the theoretical and practical implications of the specific project. Table of contents Executive Summary 2 1. Introduction 4 2. British Airways – Outsourcing of Aircraft maintenance services 4 2.1 Company overview 4 2.2 Aircraft maintenance services – industry characteristics 5 2.3 Outsourcing of Aircraft maintenance services 5 2.3.1 Brazil 5 2.3.2 Mexico 6 2.3.3 Ukraine 7 2.4 Outsourcing as a business strategy – theoretical perspectives 8 2.5 Conclusion 9 Re ferences 10 Appendix 13 1. Introduction The effects of firms’ strategic decisions can be quite important influencing the organizational performance either in the short or the long term. For this reason, when managers have to develop a critical strategic decision need to review all parameters of the relevant plan, taking into consideration potential failures or unexpected problems. In the Aviation industry a similar approach has to be used when such decisions need to be developed. This paper focuses on the potential effects of the decision of British Airways (BA) to outsource part of each supply chain activities, its aircraft maintenance services. There are three countries that have been reviewed, as of potential targets of this strategy: Brazil, Mexico and Ukraine. Each of these countries has been involved in such activities, but not at the same level. For example, Mexico has been found to be a country that can effectively support all aspects of outsourcing in regard to an ai r carrier’s aircraft maintenance services. The other two countries, Brazil and Ukraine seem to be less developed in this sector; still, Brazil and Ukraine also can offer a series of benefits to firms that would decide to outsource their aircraft maintenance services to these countries. The theoretical aspects of outsourcing, as a common business strategy are also presented in this paper, aiming to highlight the implications that BA would have to face in case it would decide to proceed to the specific plan, i.e. to outsource its aircraft maintenance services to Brazil, Mexico or Ukraine. 2. British Airways – Outsourcing of Aircraft maintenance services 2.1 Company overview British Airways is a major competitor in the global aviation industry. The firm was first established in 1919 under the name ‘Aircraft Transport and Travel Limited (AT&T)’ (British Airways History 2012). In the decades that followed the growth of the firm was significant (British Airways History 2012). At the end of 2011 the fleet of the company was estimated to ‘245 aircrafts’ (IAG About Us). In 2011, January, BA was merged with the Spanish Air Carrier, Iberia (IAG About Us); the firm resulted has been IAG, International Airlines Group, a firm based in Spain (IAG About Us). The financial performance of BA, as a member of IAG can be characterized as quite important, as indicating in the financial report of IAG, the parent company, for 2011 (Figure 4, Appendix).

Presentation of statistics using a frequency Research Paper

Presentation of statistics using a frequency - Research Paper Example It would be prudent to depict the same by means of Table 2.1 as shown below: Table 2.1: Use of frequency distribution in reporting data # Purpose Frequency distributions used 1 Duration of unemployment 27 weeks 2 Employment status by age 16-19 years, 16-17 years, 18-19 years, > 20 years, 20-24 years, >25 years, 25-54 years, 24-34 years, 35-44 years, 45-54 years, >55 years, 16 years and over, 20 years and over, 16-64 years,>65 years (many mutually inclusive ranges, used differently at different places) 3 Employment status by education level Less than high school, High school but no college, Some college or associate degree, Bachelor’s degree & higher (Qualitative ranges) 4 †¦. 3. Conclusions drawn The major conclusion drawn from this study was that the number of unemployed persons in August was 14 million, almost the same as previous month. Also the unemployment rate stood at 9.1%. Frequency distributions had a role to play in other conclusions. It was concluded that the n umber of long term unemployed (>27 weeks duration) was 42.9% of the total unemployed. The unemployment rates for adult men (18 and over), adult women (18 and over) and teenagers (16-19) showed little monthly changes. Also as expected the unemployment rate was inversely proportional to the level of education of a person. 4. Scales of measurement Table 4.1 gives a snapshot of the important variables and the scales of measurement used for them. Table 4.1: Scales of Measurement of Variables # Variable Scale of Measurement 1 Population Ratio 2 Number of Employed / Unemployed Ratio 3 Unemployment rate Ratio 4 Age Interval 5 Education Interval 6 Duration of unemployment Interval 7 Type of industry Nominal 8 Race of population Nominal 9 Veteran status Nominal 10 Class of workers Nominal 11 Occupation Nominal 12 †¦. 5. Effectiveness of the presentation The presentation of employment data gives a comprehensive view of the unemployment status in U.S.. The data has been segregated form all practical dimensions and categories. The use of frequency distributions for education and duration of employment seems appropriate. However, for age, many frequency distributions have been used at multiple places. Many of these frequency ranges are mutually inclusive. This leads to a lot of confusion for the viewers of the report. The ranges for age need to be standardized in order to present a clear picture of employment status by age. In addition to this, there is another scope for improvement in the report. It is in terms of representing numbers through bar graphs and pie charts. This would help the viewer in getting a quick snapshot of the numbers and percentages rather than current process where various tables need to be scanned through to come to a conclusion. 6.

Introduction to statistics - Essay Example Line graphs also allow us to see overall trends such as an increase or decrease in data over time. Clearly, looking at the graph we don’t observe any disparity in the data given The intuition can further be confirmed from the t-test significance analysis conducted. From the table below, the percent of goods moved in the year 2000 was 16.53 while that moved in the year 2009 was 15.69, this shows no significant difference. Also from the same table (table 2), we observe that the p-value=0.206>0.05 (significance level), we thus fail to reject the null hypothesis and conclude that indeed there is no significant difference in the goods moved in the year 2000 and those moved in the year 2009. In this part we regressed the 2009 data on the 2000 data since the data was found to follow a normal distribution we opted to use a parametric test (Bivariate regression analysis), we used bivariate because we only had two variables to test (simple linear regression) and the model produced

Factors Affecting The Rate Of Enzymes Activity Biology Essay

Factors Affecting The Rate Of Enzymes Activity Biology Essay Enzymes are catalysts made within the human body. Catalysts naturally, lower the activation energy required for reactions. The lower the activation energy is, the faster the rate of reaction is, and therefore enzymes speed up reactions in the body by lowering the activation energy required. (Diet-Health.net) There are many factors that contribute to the rate of reaction of an enzyme. Factors include: concentration of the enzyme, temperature, pH level, concentration of the substrate, and inhibitors. This lab shows the affects these factors have on the rate of reaction between catalase, an enzyme found in potatoes, and hydrogen peroxide, the substrate. The specific enzyme that was studied during this lab was catalase. Catalase is a naturally occurring enzyme that is found in many living organisms such as plants and the human body. Catalase breaks down hydrogen peroxide, a very harmful oxidizing agent for cells (Catalase). A single catalase molecule can break down millions of hydrogen peroxide molecules in a given moment. Catalase breaks down hydrogen peroxide into water and oxygen. Hydrogen peroxide is a natural waste product which forms when the body breaks down fatty acids and converts that into energy. Hydrogen peroxide also forms when white blood cells break down and kill bacteria in the body. Catalase is also helpful in prevent the formation of carbon dioxide bubbles in the blood. Catalase can help break down other harmful chemicals in the body such as alcohol, phenol, and formaldehyde (VitaminStuff.com). As mentioned before, enzymes play a significant role in organic chemistry. Catalase is one of the most recognized enzymes found in living organisms. This lab provides the clear and understandable information of the enzyme being studied, catalase, and proves the affects of the factors that contribute to an enzymes rate of reaction. Part 1: Change in Enzyme Concentration Table 1: Enzyme concentration compositions Distance (cm) Time (s) Rate of Change (cm/s) Other observations 100 % concentration (10 mL potato juice) 8 cm 3.02 s 2.65 cm/s bubbles appeared 80 % concentration (8 mL potato juice, 2 mL distilled water) 8 cm 5.06 s 1.58 cm/s fewer bubbles than previous composition 60 % concentration (6 mL potato juice, 4 mL distilled water) 8 cm 6.28 s 1.27 cm/s fewer bubbles than previous composition 40% concentration (4 mL potato juice, 6 mL distilled water) 8 cm 7.5 s 1.07 cm/s fewer bubbles than previous composition 20% concentration (2 mL potato juice, 8 mL distilled water) 8 cm 19.65 s 0.41 cm/s no bubbles appeared Graph 1: Analysis 1: According to the observation graph 1, the major trend shows that as the concentration of the catalase, which is in the potato juice, increases there is also an increase in the rate of reaction. As the concentration of the catalase decreased, the rate of reaction also decreased. Part 2: Change in Temperature Table 2: Temperature ( °C) Distance (cm) Time (s) Rate of Reaction (cm/s) 10.0 8.00 5.85 1.38 21.0 8.00 4.83 1.66 35.0 8.00 2.99 2.68 50.0 8.00 4.21 1.90 80.0 8.00 5.52 1.45 Graph 2: Analysis 2: Observation graph 2 shows the relationship between the environmental temperature and the rate of reaction. According to the observation chart the optimal temperature was 35 °C. The optimal temperature being the temperature at which the enzyme reacted the fastest. Any temperature higher or lower than 35 °C, the catalase molecules did not react as fast. Part 3: Change in pH Level Table 3: Amount of H2O2 (mL) Amount of Distilled Water (mL) Amount of pH Buffer (mL) pH Level Vertical Distance Travelled by Filter Paper Towards Meniscus Time taken by filter paper disc to move to meniscus (s) Upward velocity of Filter Paper Disc (cm/s) 10 mL 5 mL 7 (Control) 8.15 6.6 1.23 10 mL 5 mL 2 7.98.15 16.65 0.47 10 mL 5 mL 4 8.15 7.05 1.16 10 mL 5 mL 9 8.1 10.4 0.78 10 mL 5 mL 12 7.85 8.14 0.96 Graph 3: Analysis 3: According to graph 3, the optimal value was the pH level of 7. At the pH level of 7, the rate of reaction was the fastest, any pH level higher or lower than that of 7 the enzymes rate of reaction would decrease. This relationship was much like that of the temperatures, anything above or below the optimal value the rate of reaction decreases. Part 4: Change in Substrate Concentration Table 4: Concentration of H202 of Distilled Water Trial Time of catalase to travel from the bottom of the test tube to the top (s) Distance of bottom of test tube to substrate(cm) Rate of change of the catalyzed reaction (cm/s) 15 mL of H202 3% 1 5.89 8.0 1.36 2 6.86 8.0 1.17 Total 6.38 8.0 1.27 13 mL of H202 2.6% 1 8.13 8.0 0.98 2 7.11 8.0 1.13 Total 7.62 8.0 1.01 10 mL of H202 2% 1 8.65 8.0 0.87 2 12.8 8.0 0.63 Total 10.73 8.0 0.75 7.5 mL of H202 1.5% 1 9.43 8.0 0.84 2 12.53 8.0 0.64 Total 10.98 8.0 0.74 5 mL of H202 1% 1 10.37 8.0 0.77 2 12.88 8.0 0.62 Total 12.63 8.0 0.70 Graph 4: Analysis 4: According to graph 4, as the concentration of the substrate (hydrogen peroxide) increases the rate of reaction also increases. This relationship was much like that of the change in enzyme concentration. Part 5: Addition of an Inhibitor Table 5: Experiment Number Amount of Inhibitor (copper (II) sulfate drops) Time (s) Distance (cm) Rate of change (cm/s) 1 0 4.13 8.0 1.94 2 1 4.68 8.0 1.71 3 5 5.57 8.0 1.44 4 10 6.66 8.0 1.20 5 15 8.57 8.0 0.93 Graph 5: Analysis 5: According to graph 5, as there was an increase in the drops of copper (II) sulphate (the inhibitor for this lab) there was a decrease in the rate of reaction. This was due to the fact that the copper (II) sulphate blocked the active site of the catalase. Evaluation: Conclusion For each part of the lab, there were hypothesis made in the beginning of the experiments. Each experiment was done and observed and a conclusion was reached on whether the hypothesis for the experiment made sense and was proven. Part 1: Change in Enzyme Concentration Hypothesis: If there was an increase in the concentration of the catalase, then there would be an increase in the rate of reaction. This hypothesis was proven to be true. As there was an increase in the concentration of the enzyme, the catalase, there was an increase in the rate of reaction. This was due to the fact that there were more catalase enzymes available for the substrates to bind to and soon react with. The concentration of the substrate was maintained at the naturally available concentration, there were no changes made. That meant that there were more active sites available to the substrates to bind to. The more the active sites there were, the more substrates were being reacted at the same time, therefore decreasing the time it took to fully react with all the substrate molecules. Table 2: Change in temperature Hypothesis: If the temperature of the environment surrounding the reaction increases the rate of reaction will also increase, until it reaches the optimal point, the point at which the rate of reaction will start to decrease. The hypothesis was proven to be true as well. The rate of reaction did increase until it reached the optimal point. At the optimal point (35 °C) the rate of reaction was the highest, which meant the most number of hydrogen peroxide molecules were reacting with the enzymes during the experiment at that specific temperature. In other words, the optimal point was when the enzymes worked the best. As the temperature rose, the molecules possessed more kinetic energy. The more kinetic energy there was, the more the molecules moved and collided with one another, increasing the rate of reaction, until it reached the optimal point. Once the temperature started to increase higher than 35 °C the catalase started to denature, which meant the shape of the enzyme would start to differ. The denaturing catalase decreased the rate of reaction because there werent as many healthy normal catalase molecules to maintain the rate or even increase it. Part 3: Change in pH Level Hypothesis: If the pH level of the substrate increased then the rate of reaction will also increase until an optimal pH level is reached. Anything above or below the optimal pH level the enzyme will denature. This hypothesis was also proven to be true. The optimal pH level was 7, neutral, for the catalase. This meant at pH 7, the most enzyme-substrate reactions were taking place at that specific time. Enzymes work within a small pH range, therefore pH levels tend to have a great impact on the enzyme-substrate activity (Nelson Biology 12). Any pH level above or below 7 started to denature the enzyme, slowing down the rate of reaction. Denaturing enzymes meant that the shape of the overall enzyme had changed. This meant that at the pH levels of 2, 4, 9 or 12 the shape of the active site for the substrate to bond to would change, slowing down the process. At the pH level of 7, catalases activity was the greatest. Part 4: Change in Substrate Concentration Hypothesis: If the concentration of the substrate (hydrogen peroxide) increases the rate of reaction also increases. This hypothesis was proven to be true. This relationship was much like that of the concentration of the catalase. As the concentration of the substrate increased the rate of reaction also increased because there were more hydrogen peroxide molecules available to react with the catalase. However, at one point (the point of saturation, which wasnt achieved in this lab) the rate of reaction would be constant. That meant at a given point during the experiment, all of the active sites of the catalase would be occupied with a hydrogen peroxide molecule and the rate of reaction would neither increase nor decrease. Strictly looking at the experiment observed, the rate of reaction was increasing as the substrate concentration was increasing because there were more substrates available to react with an enzyme at a specific time. Part 5: Addition of an Inhibitor Hypothesis: If the addition of an inhibitor increased then that means the rate of reaction would decrease. This hypothesis was also proven correct. The copper (II) sulphate acted as an inhibitor for the experiment. When added, the copper (II) sulphate attached itself to the active site of the catalase molecules, causing the rate of reaction to decrease. The copper (II) sulphate was meant to block the active site, which it did successfully, hence the decrease in the rate of reaction. This meant, the more copper (II) sulphate was added the lower the rate of reaction would be. This is because this inhibitor stalls the reaction time because there are less reactions taking place at that moment in time, due to the fact that the active sites are blocked off from the hydrogen peroxide molecules. Evaluation: Sources of Error Throughout this lab there were many errors made that were uncontrolled and/or unaccounted for. These errors were not human errors, which were tried to be reduced to the minimal if not none. Some sources of error included: the test tube measurements, errors regarding the filter paper disc and the inconsistent concentration of the catalase. The test tubes were meant to be all the same shape and hold the same amount. However this was not the case for every single test tube. To the human eyes the amount in the test tube might look the same but in reality the amount might vary. This is due to the fact that the test tubes from the inside do not all have the same shape, after all test tubes are human made and there is a chance of major human error during that process as well. The test tubes not being consistent meant that there was room for error in measurements. Even though the volume of the catalase and the hydrogen peroxide were measured out precisely, the measurements that were made using a ruler were not. This was due to the fact that the test tubes were not all the same, and that the human eye is not precise in analyzing such measurements. This meant there were countless errors throughout the lab. For many processes the filter paper disc, which was dipped in the potato juice, did not always sink to the bottom of the test tube. Even with the help of forceps and plastic pipettes, which were used to aid the filter paper disc to the bottom of the test tube, the filter paper disc did not reach the bottom. This was because the catalase that was absorbed into the filter paper disc automatically started reacting with the hydrogen peroxide. They were very inconsistent, some filter paper discs took a longer time to be pushed to the bottom and others simply sank, and since time was a major aspect to the lab this caused many errors. Catalase concentration was also a source of error. There were many potatoes that were ground and made into potato juice for the purpose of this lab. Naturally, they would carry different concentration of catalase because of the different ways they were grown. There might be a potato that had many nutrients while it was still maturing in the field and a potato that barely got any nutrients. The concentration of the catalase used in one part of the lab would be higher or lower than the concentration of the catalase used in another part because of the different potatoes used. This affected the lab because, like observed before, the higher the concentration of the catalase the higher the rate of reaction there will be. In the future, if only one potato was ground and made into potato juice would help control this aspect of the lab. These were only three main errors observed during this lab. There were many more, regarding the separate sections of the lab. Evaluation: Next Steps Throughout this lab there were many procedures that could have been done differently or to a different point. Another lab could have been carried out with another natural enzyme which could have been comparable to the factors and affects of catalase. Also, the saturation level was undiscovered for the enzyme (in terms of concentration, and the inhibitors). Both are procedures that could have been carried to obtain a better understanding of enzymes. Another miniature lab would have been helpful if done, because then the factors and the affects these factors had on the rate of reactions could have been compared for a better understanding. There is another naturally occurring enzyme that shares characteristics with catalase. This enzyme is called amylase. Amylase is a catalyst that hydrolysis polysaccharides starch into disaccharide maltose. Amylase can be found in the saliva, produced in the salivary glands and the pancreas. If amylase is added to starch solution, the starch will soon break down to form maltose (Enzyme Lab). Both catalase and amylase are natural occurring enzymes found in the human body and they are great for comparison with one another. If the same lab was done with amylase this lab would help others understand a little more in the similarities and differences between enzymes. One other suggestion would be to carry out the experiments to the full potential. After reading and studying enzymes, it is clear that there are saturation points for the substrate concentration and the affects of an inhibitor (Nelson Biology 12). Saturation points refer to the point at which there is no increase or decrease in the rate of reaction between the catalase and hydrogen peroxide. The experiment that required the increase in the substrate concentration could have been (and should have been) carried out until the point of saturation was observed. This is when the rate of reaction stays at a constant because all the active sites are occupied by hydrogen peroxide molecules and no other reactions can occur. This could have also been possible with the inhibitor part of the lab. At one point no reactions would occur because the inhibitors would have been blocking all the possible active sites for the hydrogen peroxide to react with. This is also referred to as a saturation point . If these saturation points were observed, there wouldve been a better understanding of the affects the different factors had on the enzyme. For future labs, both these processes should be considered, if not acted upon. With both processes there is the availability to further the understanding of enzymes and their capabilities in living organisms.

Drinking and Driving Essay -- Drunk Driving Alcohol DUI Influence Essa

Drunk driving is considered a serious crime in every state. It is wrong, irresponsible and wastes many lives. People who abuse alcohol hurt everyone around them, endanger public safety, and create carnage on the nation's highways. There is nothing positive that can come out of drunk driving, so why do people do it? It is society's job to punish these menaces and try to take control of this out of control issue. America doesn't want to watch idly as hundreds of people are killed each day. We want to take a stand and let the world know that we may be the 'land of the free and the brave' but there is nothing brave or free about driving drunk. What should be done about this problem is debatable and certainly open to discussion, but the first step is lowering the BAC (blood alcohol concentration) level from .10 to .08. Many states have already done this and I commend them on this decision, but the government needs to mandate this to all the states. Some people oppose this decision and sa y that it is based on 'emotion, personal vendettas, and irrational, sound public policy, nor backed up by statistical data.'( DWI Dilema, Internet source) However, I disagree. We need to send the message that it is not acceptable, nor is it constitutional to drive under any influence of alcohol, weather it be .08 or .20.   Ã‚  Ã‚  Ã‚  Ã‚  ?Drunken driving was once treated much as car accidents?a regrettable but unavoidable part of life on the roads. But a vocal grass-roots movement led my MADD (Mothers Against Drunk Driving) persuaded much of the country, over two decades, to view it as a type of criminal negligence. Public patience with drunk drivers quickly grew thin as well-publicized death tolls mounted. ( Mishra, Internet source)   Ã‚  Ã‚  Ã‚  Ã‚  What exactly is drunk driving? This is a question that has yet to be answered. ?To determine the concentration of alcohol in the body at any given time, it is necessary to establish the blood alcohol concentration (BAC), which measures the percentage of alcohol in the blood. When a person consumes more alcohol than his or her body can immediately eliminate, alcohol accumulates in the bloodstream and the BAC rises.?(Henderson, 23) In Connecticut the BAC level is .08, this means that the blood alcohol level needed to be arrested for drunken driving has to be .08 or higher. ?One can also be convicted of drunk driving without the results of a blood alcoho... ...st charge of failure to appear carries the potential penalty of 1 year in jail and/or a $2,000 fine.   Ã‚  Ã‚  Ã‚  Ã‚  America is not putting a deaf ear to the war on drunk driving. It is far from over, but every step we take to get it under control, is a step toward drying it up. Lowering the BAC level is just the first step, we still have a long journey ahead of us. Connecticut has taken a stand and been one of the twelve states to lower their legal BAC level to .08. I truly agree with this decision, and hope that other states will follow our lead. ?Strict criminal prosecution of alcohol-impaired drivers is the most effective deterrent in reducing the menace of alcohol-impaired driving.?(Henderson, 108) This battle isn?t just between people who are old enough to drive as well as drink. Teenagers, much like my self, are taking action against drunk driving. In Hamden High School we have a very active club called S.A.D.D.(Students against Drunk Driving) This club makes young people aware of the dangers of driving even after drinking small amounts of alcohol. This is an issue that i s not to be taken lightly, and it certainly isn?t. I just hope that one day, this issue will be non-existent.
