Mass Relationships in Chemical Reactions Essay

Aim The aim of this experiment is to show that a reaction doesn’t have always 100% yield by reacting NaHCO3 and HCl and determining the amount of the products to calculate actual yield. Introduction A chemical reaction will be quantitative if one of the reactants is completely consumed. In this experiment sodium bicarbonate and hydrochloric acid start a reaction. The formula of this reaction is below. NaHCO3 + HCl –> NaCl + H2O + CO2 Observations In this experiment, sodium bicarbonate is put in an evaporating dish and some amount of HCl is added in the dish and the reaction started. Bubbles are formed and CO2 gas is produced and the reaction started to make sound. There was also water vapor formed. White NaHCO3 started to turn into a colorless liquid after adding HCl. As the reaction takes place water is started to form. NaCl was dissolved in water, so salty water is heated to obtain NaCl. As the liquid is heated it turned into a yellowish color for a few seconds. Then it started bubbling and water vapor is formed. Raw Data: Trial # Mass of Dish+NaHCO3+Lid +- 0.1 (g) Mass of NaCl+Water+Dish+Lid +- 0.1 (g) Mass of NaCl+Dish+Lid +- 0.1 (g) 1 64.14 g. 72.16 g. 63.28 g. 2 65.14 g. 72.95 g. 63.91g. Mass of Evaporating Dish + Lid: 62.14 +-0.1 g Processed Data: Trial #1 64.14 – 62.14 = 2 g NaHCO3 72.16 – 62.14 = 10.02 g NaCl + H2O 63.28 – 62.14 = 1.14 g NaCl Trial # 2 65.14 – 62.14 = 3 g NaHCO3 72.95 – 62.14 = 10.81 g NaCl + H2O 63.91 – 62.14 = 2.07 g NaCl Trial # Mass of NaHCO3 (g) Mass of NaCl + H2O (g) Mass of NaCl (g) 1 2 g 10.02 g 1.14 g 2 3 g 10.81 g 1.77g Calculations Na: 14.01 g/mol, H: 1.01 g/mol, Cl: 35.45 g/mol, O: 16 g/mol, C: 12.01 g/mol NaCl= 49.46 g/mol H2O= 18.02 g/mol NaHCO3: 75.03 g/mol Mole number of NaHCO3 = mole number of NaCl Trial #1 2 / 73.03 = 0.0274 mol NaHCO3 1.14 / 49.46 = 0.0230 mol NaCl Theoretical Yield: 0.0274 mol NaCl Percent Yield: 0.0230 / 0.0274 = 0.8394 x 100 = 83.94% Trial #2 3 / 73.03 = 0.0411 mol NaHCO3 1.77 / 49.46 = 0.0358 mol NaCl Theoretical Yield: 0.0411 mol NaCl Percent Yield: 0.0358 / 0.0411 = 0.8710 x 100 = 87.10% Conclusion The results are 83.94% for trial #1 and 87.10% for trial #2. Trial #2 is more accurate. The accepted value is 100%. The percentage errors are 16.06% for trial #1 and 12.90% for trial #2. The uncertainties are too small to calculate on the results. Random errors presented in this experiment. All the errors were done by human beings. There weren’t any errors due to a flaw of a machine or the procedure. Evaluation When salty water is heated on the first trial, the substance started to spill around, because the substance is heated with high amount of heat and faster than it should be. As a result, some of the NaCl which stuck on the lid and spilled around was lost, so the result of the first experiment is not accurate. Other reasons that changed the results may be all NaHCO3 may not be dissolved. Too much HCl may be added on the dish. There may be still water molecules left on the salt after heating. To get more accurate results, the experiment should be done more slowly than this experiment. Especially the heating process should be done slowly, so the evaporation can be observed more carefully.

The Twilight Saga 5: Midnight Sun 18. Stories

I was worried that if I were to divulge the information that she would request that she would decide to never grace me with her presence again. I decided this was the best time to release some of our stories. She hadn't run away yet. I knew I would feel relieved once she knew the truth. â€Å"Carlisle was born in London, in the sixteen-forties, he believes. Time wasn't marked as accurately then, for the common people anyway. It was just before Cromwell's rule, though.† I began. I watched her face carefully for any sign of distress. She showed no emotion. I continued, â€Å"He was the only son of an Anglican pastor. His mother died giving birth to him. His father was an intolerant man. As the Protestants came into power, he was enthusiastic in his persecution of Roman Catholics and other religions. He also believed very strongly in the reality of evil. He led hunts for witches, werewolves†¦and vampires.† Her pulse began picking up at the last word; I continued without pausing, â€Å"When the pastor grew old, he placed his obedient son in charge of his raids. At first Carlisle was a disappointment; he was not quick to accuse, to see demons where they did not exist. But he was persistent, and more clever than his father. He actually discovered a coven of true vampires that lived hidden in the sewers of a city, only coming out by night to hunt. In those days, when monsters were not just myths and legends, that was the way many lived. â€Å"The people gathered their pitchforks and torches, of course,† I laughed in a non humorous way at the thought of a human bringing harm to a vampire. I continued, â€Å"and waited where Carlisle had seen the monsters exit into the street. Eventually one emerged.† I knew I had arrived at the part of the story where I wasn't sure how to proceed. I went on, but kept my voice low, â€Å"He must have been ancient, and weak with hunger. Carlisle heard him call out in Latin to the others when he caught the scent of the mob. He ran through the streets, and Carlisle ?C he was twenty-three and very fast ?C was in the lead of the pursuit. The creature would have easily outrun them, but Carlisle thinks he was too hungry, so he turned and attacked. He fell on Carlisle first, but the others were close behind, and he turned to defend himself. He killed two men, and made off with a third, leaving Carlisle bleeding in the street.† I paused. The images that were in my mind were of the agony that he felt. The pain of the venom breaking through his veins and causing him to burn for days was forefront in my mind. I met Bella's eyes and she was eager for me to continue. â€Å"Carlisle knew what his father would do. The bodies would be burned ?C anything infected by the monster must be destroyed. Carlisle acted instinctively to save his own life. He crawled away from the alley while the mob followed the fiend and his victim. He hid in a cellar, buried himself with rotting potatoes for three days. It's a miracle he was able to keep silent, to stay undiscovered. It was over then, and he realized what he had become.† My eyes had never left Bella's. Most of the color had drained from her face during my story. She didn't know much of the transformation process and I am sure that she was learning some things that she hadn't known before. She was silent and I was worried I had gone too far, â€Å"How are you feeling?† I asked. â€Å"I'm fine,† she said automatically. She hadn't convinced me though. In a nervous gesture, she began biting at her lower lip. She looked like she wanted to say something; she was hesitating. Curiosity was burning in her eyes. She was regaining her color and I was becoming frustrated once again at the silence of her knowing mind. â€Å"I expect you have a few more questions for me.† I guessed. â€Å"A few.† Of course she did, she was always curious; always interested in things she shouldn't be interested in. â€Å"Come on, then,† I smiled, â€Å"I'll show you.† We turned around and I brought her back to Carlisle's office. I'm guessing you want to show her the pictures, Carlisle wondered, â€Å"Come in,† he invited. I slowly pushed the door open. Carlisle was sitting behind his desk in his leather chair. Perfect timing, Carlisle thought, â€Å"What can I do for you?† he asked. Carlisle rose from his seat. He was already aware of what I was up to, but I didn't want Bella to think we were having our normal silent conversations. â€Å"I wanted to show Bella some of our history. Well, your history, actually,† I explained to him. â€Å"We didn't mean to disturb you,† Bella apologized. Silly Bella, I thought. She sure is polite, isn't she? Carlisle smiled, â€Å"Not at all,† he looked at me, â€Å"Where are you going to start?† he asked. I had many stories in mind and I decided I would start out as simple as Carlisle's story could ever be, â€Å"The Waggoner.† I placed my hand on Bella's shoulder. An electric shock rose up my arm and through my body. I knew she felt it too because her heart starting pounding, her pulse racing. Does that always happen? To deny yourself what you crave most when her pulse rises is truly significant in your relationship. You two are truly meant to be together. Carlisle's thoughts continued more to himself. I turned Bella to face an oil painting that was on the wall behind her, ignoring Carlisle. I could tell that she was interested again. â€Å"London in the sixteen-fifties,† I explained. I knew questions must have been racing through her mind. Carlisle walked up behind Bella. His continuous flow of thoughts had stopped, â€Å"The London of my youth,† he added. Bella must not have realized he was behind her because she recoiled at the sound of his voice. I squeezed her hand. â€Å"Will you tell the story?† I wondered. I didn't want to get anything wrong, or put my foot in my mouth. I'm sorry. You will have to explain it to her because I must leave for work. Don't worry, you'll do fine. Carlisle thought. â€Å"I would,† he turned to Bella, â€Å"But I'm actually running a bit late. The hospital called this morning ?C Dr. Snow is taking a sick day. Besides,† his eyes met mine, â€Å"you know the stories as well as I do.† Carlisle had a wide smile across his face. Carlisle gave Bella a warm smile and ducked out of the room. I looked at Bella, nervous about this conversation. I was still waiting for the wailing and screaming. A sickening jolt surged through my stomach at the thought of her leaving. Her eyes were fixed on the painting. â€Å"What happened then?† she asked eagerly while removing her eyes from the painting and meeting my gaze, â€Å"When he realized what had happened to him?† My eyes moved from her face to another painting. She followed my gaze. â€Å"When he knew what he had become,† I said in a low voice, â€Å"he rebelled against it. He tried to destroy himself. But that's not easily done.† â€Å"How?† Bella asked with shock present on her face. I contained a sigh, â€Å"He jumped from great heights,† my voice stoic, â€Å"He tried to drown himself in the ocean†¦but he was young to the new life, and very strong. It is amazing that he was able to resist†¦feeding†¦while he was still so new. The instinct is more powerful then, it takes over everything. But he was so repelled by himself that he had the strength to try to kill himself with starvation,† I explained. I knew at any moment she would comprehend my words and descend the stairs and quickly exit the house. â€Å"Is that possible?† she asked darkly. â€Å"No, there are very few ways we can be killed.† I saw her open her mouth and I rushed to get the words about before she could ask me another question, â€Å"So he grew very hungry, and eventually weak. He strayed as far as he could from the human populace, recognizing that his willpower was weakening, too. For months he wandered by night, seeking the loneliest places, loathing himself â€Å"One night, a herd of deer passed his hiding place. He was so wild with thirst that he attacked without a thought. His strength returned and he realized there was an alternative to being the vile monster he feared. Had he not eaten venison in his former life? Over the next months his new philosophy was born. He could exist without being a demon. He found himself again. â€Å"He began to make better use of his time. He'd always been intelligent, eager to learn. Now he had unlimited time before him. He studied by night, planned by day. He swam to France and ?C† â€Å"He swam to France?† Bella shrieked incredulously. I had to compose my face because I was trying desperately not to laugh at her reaction, â€Å"People swim the Channel all the time, Bella,† I reminded her. She blinked foolishly, â€Å"That's true, I guess,† shock was evident in her eyes still, â€Å"It just sounded funny in that context. Go on.† â€Å"Swimming is easy for us ?C† â€Å"Everything is easy for you,† she interrupted, a little perturbed. I paused, waiting for her to ask another question. The look on her face was very comical. Her mouth hung open a little and her eyes were wide with surprise. She was quick to perceive my obvious reason for hesitating before I continued, â€Å"I won't interrupt again, I promise,† she said with a small smile. I laughed because I knew that she would interrupt again when she hears what I have to say next, â€Å"Because, technically, we don't need to breathe,† I began until Bella burst out, â€Å"You ?C â€Å" â€Å"No, no, you promised,† I laughed because I knew that when she heard this bit of information that her reaction would be exactly what it was now. Her face was screwed up in longing to finish her questioning. I brought my finger to her lip to silence her, â€Å"Do you want to hear the story or not?† She spoke with my finger pressed lightly against her warm lips, â€Å"You can't spring something like that on me, and then expect me not to say anything.† Her voice was mumbled, trying to speak past my silencing finger. I traced my finger down her jaw and stopped at her neck. My stomach did summer-salts when her pulse speed by my touch. I had momentarily forgotten about the story or where we were. It was just Bella and I, together. â€Å"You don't have to breathe?† her eyes were still wide with interested; her question bringing me to the present. â€Å"No,† I answered, instantly nervous that this proclamation would be the thing that scares her away, â€Å"it's not necessary. Just a habit.† I shrugged, showing her how little it really mattered. She dropped her voice, almost conspiratorially, â€Å"How long can you go†¦without breathing?† â€Å"Indefinitely, I suppose; I don't know. It gets a bit uncomfortable ?C being without a sense of smell.† I tried to explain very nonchalantly. â€Å"A bit uncomfortable,† she mirrored. I continued to look at her face. Each expression fluttered across with little time to settle. Her eyebrows pulled together and I wanted to take my thumb and smooth out the complexity lines. Trying to understand her thoughts was like trying to read sign language unknown to humans. A new speculation loomed in my mind. I removed my hand from her, letting the cold return. Something was eating at me from the inside. I was bringing her into this mythical world. Each new revelation bringing her closer to the doom I was prepared to fight. Bella's face grew very grave. She was watching my expressions now, â€Å"What is it?† she asked gently. She brought her hand to my face, trying to comfort me. I felt each pump of her blood. Her hand warmed my cheek to several degrees than my normal temperature. I sighed because I knew that I was inviting her to tempt fate and that I would allow it. â€Å"I keep waiting for it to happen.† I said quietly. â€Å"For what to happen?† she asked urgently. â€Å"I know that at some point, something I tell you or something you see is going to be too much. And then you'll run away from me, screaming as you go,† I pasted a smile across my face, trying to ease the tension building inside me, â€Å"I won't stop you. I want this to happen, because I want you to be safe. And yet, I want to be with you. The two desires are impossible to reconcile†¦Ã¢â‚¬  I kept my eyes fixed on her, waiting for her to agree with me and just leave. There was a long and painful silence before either of us spoke again. â€Å"I'm not running anywhere,† Bella promised with obvious triumph in her voice, like she was looking fate in the eye and taunting it. I remembered the story, and thought that if I continued maybe, just maybe, she would hear something that would scare her away, â€Å"We'll see,† I smiled. Her lips turned down at the corners, a frown forming on her face, â€Å"So, go on ?C Carlisle was swimming to France.† I caught my breath, delighting in the ever present yearning in my stomach. I moved my gaze from her face to another painting deciding to continue, â€Å"Carlisle swam to France,† I repeated, â€Å"and continued on through Europe, to the universities there. By night he studied music, science, medicine ?C and found his calling, his penance, in that, in saving human lives. I can't adequately describe the struggle; it took Carlisle two centuries of torturous effort to prefect his self-control. Now he is all but immune to the scent of human blood, and he is able to do the work he loves without agony. He finds a great deal of peace there, at the hospital†¦Ã¢â‚¬  I trailed off, my thoughts moving in a different direction. I willed myself to be like Carlisle. I wished to have his self control, to never have to second guess my senses. I inhaled; something I used to do to calm myself, but now it brought red hot flames ripping down my throat. I mentally shut out the yearning I had now. I remembered what my purpose was for this conversation. I brought my hand to the painting in front of us, tapping lightly on it. â€Å"He was studying in Italy when he discovered the others there. They were much more civilized and educated than the wraiths of the London sewers.† I said while lightly tracing the figures in the picture; the Volturi. I was so deep in thought, remembering things that Carlisle had seen when a startled laugh burst out of Bella's lips. I turned to see what the matter was; thinking that maybe she finally had lost it. Dawn crossed my face as I realized what she was looking at. It was Carlisle's face in the painting with the Volturi. â€Å"Solimena was greatly inspired by Carlisle's friends. He often painted them as gods,† I laughed at the impossibility that any vampire could ever be a god, â€Å"Aro, Marcus, Caius,† I explained as I pointed each one out to her, â€Å"Nighttime patrons of the arts.† Her eyes darted from the painting to me face, â€Å"What happened to them?† she questioned. Her hand reached up to touch the figures in the painting but her finger never touched. â€Å"They're still there,† I shrugged, â€Å"As they have been for who knows how many millennia. Carlisle stayed with them only for a short time, just a few decades. He greatly admired their civility, their refinement, but they persisted in trying to cure his aversion to ‘his natural food source,' as they called it. They tried to persuade him, and he tried to persuade them, to no avail. At that point, Carlisle decided to try the New World. He dreamed of finding others like himself. He was very lonely, you see. â€Å"He didn't find anyone for a long time. But, as monsters became the stuff of fairy tales, he found he could interact with unsuspecting humans as if he were one of them. He began practicing medicine. But the companionship he craved evaded him; he couldn't risk familiarity. â€Å"When the influenza epidemic hit, he was working nights in a hospital in Chicago. He'd been turning over an idea in his mind for several years, and he had almost decided to act ?C since he couldn't find a companion, he would create one. He wasn't absolutely sure how his own transformation had occurred, so he was hesitant. And he was loath to steal anyone's life the way his had been stolen. It was in that frame of mind that he found me. There was no hope for me; I was left in a ward with the dying. He had nursed my parents, and knew I was alone. He decided to try†¦Ã¢â‚¬  During my story telling, I had visualized everything that Carlisle and I had both witnessed during the few days before and after my transformation. The painful memory was something I rarely thought of these days. I looked out the window, banishing the unpopular imagines from my mind. My chest was swelling at the relief I felt for finally releasing the information that could doom me from ever seeing this delightful creature again. The feeling of happiness that was surging through my body at this moment in time was completely indescribable. I hadn't realized that I would feel like this, too; that knowing she wasn't running, that she was one hundred percent accepting. I returned my gaze to Bella. She looked humble and my lips turned up; an automatic response to her beauty. â€Å"And so we've come full circle,† I finished. â€Å"Have you always stayed with Carlisle, then?† she asked. She was constantly asking all the questions that gave everything away about me and nothing about her, â€Å"Almost always,† I replied. I slowly reached out and placed my hand on her waist, exaggerating the movement. I delicately moved her along with me, always remembering how fragile she was. â€Å"Almost?† Bella asked while we were walking down the hall. Crap, I thought. Why was this the one question, of all the questions, to ask? I knew I would give her the answer. The internal argument of her safety still loomed in my mind. She should stay away from me but I loved her and the thought of her leaving caused me physical pain. Pain was something I hadn't felt since before the transformation. Bella brought out all the human aspects of me, including the weakness of pain. I sighed, â€Å"Well, I had a typical bout of rebellious adolescence ?C about ten years after I was†¦born†¦created, whatever you want to call it. I wasn't sold on his life of abstinence, and I resented him for curbing my appetite. So I went off on my own for a time.† I explained. Now, this would be it, the thing that makes her scream in terror. I waited, but, instead of terror she was intrigued. â€Å"Really?† she asked her eyes wide with curiosity. She wasn't frightened? I admitted to killing humans and she was†¦curious. She is so peculiar. That was an understatement. She had lost her mind. We ascended the next set of stairs. I was leading her to my room. I turned and looked at her, â€Å"That doesn't repulse you?† I asked curtly. â€Å"No.† â€Å"Why not?† â€Å"I guess†¦it sounds reasonable,† she said firmly. A laugh escaped my lips as I thought of the absurdity of her answer. Horrified delight sliced through my veins. â€Å"From the time of my new birth,† I replied quietly, â€Å"I had the advantage of knowing what everyone around me was thinking, both human and non-human alike. That's why it took me ten years to defy Carlisle ?C I could read his perfect sincerity, understand exactly why he lived the way he did. â€Å"It took me only a few years to return to Carlisle and recommit to his vision. I thought I would be exempt from the†¦depression†¦that accompanies a conscience. Because I knew the thoughts of my prey, I could pass over the innocent and pursue only the evil. If I followed a murdered down a dark alley where he stalked a young girl ?C if I saved her, then surely I wasn't so terrible.† I watched as she shivered. I continued in my quest to be nothing but honest with her, â€Å"But as time went on, I began to see the monster in my eyes. I couldn't escape the debt of so much human life taken, no matter how justified. And I went back to Carlisle and Esme. They welcomed me back like the prodigal. It was more than I deserved.† I stopped in front of my bedroom door, â€Å"My room,† I told her while opening the door and leading her inside. I watched her as she took in everything. Her eyes flowed rapidly from one side of the room to the other. Her stare lingered on my CD's. â€Å"Good acoustics?† she asked. My good mood was vibrant now. The pain from not knowing today's outcome had subsided. I was radiant with glee. I chuckled and nodded at her question. I decided I would give her an example and turned the stereo on from a remote. When the jazz music began to play she whirled spectacularly in a circle, delight in her eyes at the sound. She stopped and moved over to my collection of music. Her eyes read through several labels, â€Å"How do you have these organized?† she asked in astonishment. I was barely paying attention to her words because I was in complete merriment of how the events unfolded today, â€Å"Ummm, by year, and then by personal preference within that frame,† I answered automatically. She turned around to face me. The whirl wind of her warm aroma hit me like a wrecking ball. I continued to breathe evenly, reveling in the pain. I couldn't shake my new found happiness that was ever present in my being. She wanted me; all of me. Her eyes met mine and she read my face, â€Å"What?† she asked. â€Å"I was prepared to feel†¦relieved. Having you know about everything, not needing to keep secrets from you. But I didn't expect to feel more than that. I like it. It makes me†¦happy.† I shrugged my shoulders, but the jubilance radiated out of me and a smile crept up my face. â€Å"I'm glad,† she replied with a smile. I continued to gaze at her. I tried to read her expressions but they were so swiftly changing since she entered this house. I willed myself once more to read her mind. I tried probing it with mine over and over to no avail. My forehead creased in concentration. â€Å"You are still waiting for the running and the screaming, aren't you?† she wondered. My lips turned up lightly and I nodded. â€Å"I hate to burst your bubble, but you're really not as scary as you think you are. I don't find you scary at all, actually,† she lied silkily. Disbelief was strong in my mind. I raised an eyebrow at this news. A sinister thought raced through my head and before I acted a wide smile spread across my face, â€Å"You really shouldn't have said that,† I laughed. I growled very un-menacingly, brought my lips above my teeth to show them off, and hunkered down. Her eyes grew wide with terror. â€Å"You wouldn't† she shrieked. I let my body recoil as I sprung.

Temple of Artemis at Ephesus - Term Paper Example At the very least, this paper aims to subjugate, criticize and analyse the aesthetic standards of the ancient people in terms of architecture and representations that pertain to worship and religious iconography since these things have played a very vital role in thriving of the artistic culture that time. What seems to be so significant about this paper is it tries to revive to the consciousness of the modern people the importance and contributions of the ancient knowledge and culture that have become one of the guiding conventions of the modern people in generating new concepts and designs related to architecture. At the same time, it tries to highlight the pivotal conditions that surround the architectural design of the Temple of Artemis at Ephesus, one of the wonders of the Ancient World. The Temple of Artemis at Ephesus was designed by the architect Chersiphron and is said to be the very first temple built out of marble and the largest Greek temple erected and measures 377 feet long and 180 feet wide (Temple of Artemis). The very first shrine was constructed around 800 B.C.E. and had major reconstructions during the 600 B.C.E., 550 B.C.E. and 356 B.C.E. (unmusem.org). However, during the reconstruction period of the temple, Theodorus, Scopas of Paros became contributing architects for Temple of Artemis (clevelys.co.uk). The Temple of Artemis was erected at the marshy fields of the Ephesus at the Asia Minor (greatbuildings.com). This temple is regarded to be one of the wonders of the ancient world (yousigma.com). Its highlights several conventions of architecture and culture present during the early human times. This architectural edifice is a treasure damaged due to several complexities that have risen during that time. Also, the historical relevance of the temple is crucial to determine the cultural influences that have penetrated the construction of the said majestic

Retail management Essay Example | Topics and Well Written Essays - 1500 words

Retail management - Essay Example The fashion industry today is marked by short life-cycles, high volatility, low predictability and high impulse purchasing (Christopher, Lowson & Peck, 2004). The fashion retail industry in UK is turbulent as the fashion conscious consumers expect and thrive for constant change. Added to the changing consumer preferences are the factors like globalization and the technological changes that have truly revolutionized the UK fashion retailing industry. The fashion retail market is split into number of segments – luxury, high street and supermarket/out-of-town discounter (Bruce & Daly, 2006). With the supermarkets having entered the clothing sector, the fashion retail has been redefined. It enables the time-starved consumers to purchase cheap clothing instead of visiting high street. The cheap chic revolution has turned the UK fashion market upside down (Mesure, 2007). With the rise of the discount retail store the number of garments purchased by women each has doubled. Various reasons have been accounted for this changing trend – shift of production to the Far East, the weak US dollar and the abolition of textile quotas have driven down prices even in chains like Asda and M&S. The phenomenon of disposable fashion rules – â€Å"buy it, wear it, and chuck it† is the mantra that the fashion conscious follow in the 21st century. Consumers expect low prices, and increasing incomes are the key to increased ec onomic activity. According to Jones and Hayes (2002), clothing and fashion purchase decisions are based on want rather than need (cited by Priest 2005). It depends upon how the consumer wants to be perceived. Competition is fierce and the market is characterized by excessive discounting. Even top socio-economic groups are price-savvy. Decreased consumer spending has a negative impact on the retailers. Besides, cost of retail space has gone up and rents have risen. According to a research by This is Money, people shop at both the top and bottom ends of

The information-processing theory basically tells about the cognitive development of an individual. The leaning of new things by the human mind is analyzed in this theory, which states that the sensory preceptors of the human mind receives information, which is then encoded and analyzed based on the perceptions and past experiences. This information is then stored in short term or long term memory depending on the nature of information. Whenever, a person learns new things, first he retrieves the previous information on the basis of which, he/she constructs new strategy to learn new things. a. ANTICIPATION: the information-processing theory helps an individual to take responsive action in course of particular situation. This response/decision is made on the basis of anticipation. Anticipation can be classified into two types: acceptor anticipation and receptor anticipation. Acceptor anticipation tells how much time an individual will take to coordinate the movement of his/her limbs. While receptor anticipation estimates the time required by a particular event to happen. The ability to anticipate the time and motion correctly is heavily dependent on past experiences and training.

Sexual Orientation - Essay Example They believe that it is imperative that the controversial issues be handled head on so that everyone concerned is able to live with relative harmony. Sexual preferences have become major issues which promote widespread inequality, thereby, necessitating an urgent need to address this in the wider interest of the society. The essay would be critically assessing the three articles on these issues taken from the book "The meaning of difference: American constructions of race, sex and gender, social class, and sexual orientation" by Karen E. Rosenblum and Toni-Michelle C. Travis. ‘The naming of sexual attraction’, an article by Michael R. Kauth, explores the sexual orientation of the people through the ages and its evolution, both in terms of acknowledgement and acceptance by the society. Kauth has maintained that sexual attraction had always been a sensitive issue that was intrinsically bound within the religious and cultural paradigms of the society. The language and the words play crucial role in defining the overall meaning to sexual orientation or behaviour. According to the article, in the 19th century, the term homosexuality was ‘adopted by psychiatrists and medical practitioners to identify a type of psychopathology and, consequently, this term implies sickness, aberrance and immaturity’ (Kauth1). Apart from the medical professionals, the powerful groups of people, who have considerable influence on the public, are the main decisive powers that define and confine the role of ‘sexual attraction’. Hence, it is for this reason that social paradigms and social values often reflect the views and ideologies of the few prominent people in power, which are carried forward through the times. In the ancient time, ‘gay’ was used to describe gaiety and happiness by the roman soldiers. Before the 19th century, sexuality or sexual preference

Magnetic Resonance Imaging (MRI) Essay Example | Topics and Well Written Essays - 1500 words

Magnetic Resonance Imaging (MRI) - Essay Example As long as metals that are Ferro magnetic are not in the magnetic field area during use, the radio waves and the magnetic fields are relatively harmless and pose no serious impacts during normal procedures. The scanner for MRI resembles a huge box that is square shaped and with a tunnel-like hole running through the middle. The user requests the child to lie down on a table that is cushioned with aids such as soft traps and foam cushions employed to ensure the child remains still during the process. A unique frame which slightly resembles a helmet is placed on the part of the body of the child that has been earmarked for observation. When the child has been set in a comfortable and appropriate position, the table begins to move by default into the tunnel of the MRI. At this point, it is crucial that the child maintains relative stillness since any movements will cause blurring of the images and hence poor results. The examiner then departs from the room but remains in constant communication with the child using an intercom. Upon starting the process of MRI, the child may experience sounds that are loud, knocking and thumping in nature that may stay for many minutes at times. Therefore, ear protections such as ear plugs or headphones are availed to protect the hearing of the child. A parent/ guardian can come along with the child’s favorite DVD so that they can watch during the process through the video goggles of the MRI or even music CDs that they can listen to during the process. Parents/ guardians who opt to remain with their children in the operation room are also given ear protection devices to lower the noise emanating from the scanner. In order to yield better image details of the MRI, intravenous contrast could be pumped into the vein of the child. Intravenous contrast is often termed a dye but is basically a liquid without color and not similar to the kind utilized in CT scans and X-rays. In case

Economics - Entrepreneur Case study Essay Example | Topics and Well Written Essays - 1750 words

Economics - Entrepreneur Case study - Essay Example This position has further been corroborated by the fact that Peter Druker described innovation as the specific function of entrepreneurship thus the first sign of the fact that Sid is an entrepreneur is the fact that he is an innovator- a person who invented something to enhance the flexibility of working within roofing industry. The so called Rail is typical example of the fact that entrepreneurs are always technically savvy persons. Creating capital is often considered as the most important activity performed by the entrepreneur (Thompson, 1999) and the fact that the assumptions made by Sid to capture 1% of the market is indicating towards the fact that he is going to start the creation of capital which would further increase his business as well as employing other persons to create further employment opportunities. However, what is most important to note here is the fact that just innovation may not be sufficient until and unless it is not backed up by the certain characteristics as well as motivations of the entrepreneur. Creativity is considered as one of the biggest motivators for the entrepreneurs to continue to carry on activities which are not only creative in nature but also have the potential to be economically successful. (Mosakowski, 1998). The so called ladder rail of Mr. Sid is an example of how creativity has been the chief source behind the fact that he continued to work on his creative ideas despite a negative response from his company. Thus from this perspective, it is also clear and evident that Mr. Sid is an entrepreneur. Finally, perseverance is the key in entrepreneurship. It helps entrepreneurs to keep going even in the fact of difficulties. This allows them to have the necessary motivational drive to keep pursuing their dreams as once an entrepreneur decide taking a chance than it become difficult to retract from the position and that is what Mr. Sid showed. Despite reduction in the sales prices offered by the major buyers, the

How Might Deprivation Lead to Crime Essay Example | Topics and Well Written Essays - 2500 words

How Might Deprivation Lead to Crime - Essay Example In these models, deprivation leads to crime by placing low-income individuals who have low returns from market activity in proximity to high-income individuals who have things that are worth taking. A formal model of deprivation and property crime in which individuals choose between legitimate and criminal activity can be found in Chiu and Madden (1998, p123-141). Most empirical tests of the economic theory of crime have been concerned with the deterrent effects of the criminal justice system in particular by how increased police activity and imprisonment rates reduce crime, and whether this reduction is due to prevention or incapacitation (Tierney 1996). In the past several studies have considered the effect on crime of deprivation, albeit indirectly through the effect of low earnings on criminal activity (Roger 2002). In contrast to the economics of crime literature, which focuses on the deterrent effects of the formal criminal justice system, social disorganization theory considers factors that diminish the effectiveness of informal social controls. Shaw and McKay (1942) identified poverty, ethnic heterogeneity, and residential mobility as the three factors that weaken networks of social control and undermine the ability and willingness of communities to exercise informal control over their members. Sampson (1987) has added family stability to this list. For social disorganization theory, deprivation causes crime indirectly by being associated with poverty. Several of the classic theories of crime, including Marxist, strain, and utilitarian rely heavily on economic factors such as poverty and unemployment to account for variations in crime rates (Shihadeh & Ousey 1998). Researchers since the nineteenth century have suggested a positive association between poverty and crime in urban areas (Tierney 1996). This may be due to the fact that the relationship between poverty and crime is contingent upon the specific crime category under consideration (Patterson 1991). In Merton's (1938, p672-682) strain theory, individuals low in the social structure are perturbed by their failure to attain the material attributes of success, and this failure is more substantial when they are confronted by the success of those around them. Unsuccessful individuals become alienated from society and commit the crime in response. Individual alienation can arise from income deprivation or from belonging to a racial minority. The predictions of strain and social disorganization theories have been subject to extensive but questionable empirical testing in the sociological literature. The influential study of Blau and Blau (1982, p114-129) found a strong relationship between measured income deprivation and homicide rates in large metropolitan areas in 1970. Such theories rely on the troubling assumption that macro-level relationships reflect the sum of a series of individual-level social-psychological processes. Blau and Blau's (1982, p114-129) prominently stated that highly stratified environments generate feelings of resentment and frustration in individuals.  

Impact of Advertisements on Consumers Choice Essay Example for Free

Impact of Advertisements on Consumers Choice Essay Bovee and Arens (1994) define advertising as the non-personal communication of information, usually paid for and usually persuasive in nature (about products and services) or ideas by identified sponsor through various media. An advertising medium is the means or conveyance by which sales message is carried to prospective customers. Advertising is many things to people. It promotes and affects our daily lives. At times people view it positively that they might find it entertaining while other advertisements are cursed, insults and deceives it. There are also times where advertisements can mislead consumers buying behaviour. Advertisers work on consumer’s attitude to achieve their goal. Influencing and affecting their buying behaviour. Perhaps advertising is the most obvious venue where the concepts of attitude formation change can be seen in application. Persuasive communications (advertisements) can be transmitted through various media print, (newspapers, magazine, books) audio (radio and telephone) audio visual (television and movies) and electronic (internet and e-mail). Consumerism is here to stay. Tomorrows consumers will be better educated, more affluent and more critical. They will probably be less concerned with status and symbols and be more anxious to get information about the product. Background of the Study Most people may not realize it, but advertising has become pervasive if only by the sheer number of advertisement people are exposed to everyday. While advertisements are generally thought as a way to sell things an underlying element can at times be missed. It is that advertising can influence and change people attitudes and can be a potent form of influence. In fact many people blamed advertisements for encouraging materialism on people because advertisers present their products as a â€Å"must have†. Those who acquire them are depicted as more confident or more popular and this gets people to buy more products. The expression that â€Å"today we live in age of advertising† is so common to hear that it has in fact become almost trite so much that the average man has not bothered to pause even briefly and bring to mind the innumerable benefits it bring to society. The rising level in the standard of living would not have been possible in the absence of advertising. For an individual to make effort to examine an advertisement. It should first and foremost capture the individuals attention. According to Fiske (1995), attention involves the process of encoding where by people take information that is outside of them and represent in their heads. It is interesting to know that while watching the favourite shows in T.V., advertisements seem to be a part of it. Sometimes they even consume more hours than the shoe itself. Nowadays, advertisement seems to rule television and radio being a sponsor on shows because of different advertisements being shown the consumers was being confused about what product to select and use because of how the advertisers promote their product. Advertising can influence buying behaviour patterns. There are also some deep rooted attitudes, practices and values that cannot be changed by advertisements. Advertising is claimed to accomplish the four basic task of: informing, persuading, reminding and changing behaviour. Statement of the Problem 1. What are the different forms of medium used by advertisements? 2. What are the factors that affect buying behaviour of the consumers? 3. How can you measure the effectiveness of an advertisement ? 4. What are the level of effectiveness in the following medium? : a. Radio b. Television c. Print ad(newspapers and magazines) 5. What are the attitudes of the following consumers towards different forms of advertisements? : a. Children (8-12) b. Teenagers(13-19) c. Adults (20-onwards) 6. Are there differences in people attitudes towards advertisements considering the following : a. Educational attainment b. Socio- economic status Significance of the Study Everyone will benefit from this study because everyone is considered as a consumer. There is hardly any person who has no personal idea concerning advertising because it is everywhere. Advertisements have become not only a source of entertainment but also of information. These touch our way of life in infinite variety of forms, some subtle, others obvious and there are those that are even blatant.

Alcohol Consumption Interventions

Alcohol Consumption Interventions To investigate how interventions may work we will look at the effects of alcohol consumption on individuals and populations, and draw attention to the search for policies that protect health, prevent health problems such as liver cirrhosis, cardiovascular disease and disability, and address the social problems associated with the misuse of alcohol consumption. What alcohol policy is why it is needed, which interventions are effective, how policy is made, and how scientific evidence can inform the policy-making process? Also looking at why the higher the average amount of alcohol consumed in a society, the greater the incidence of problems experienced by that society. We will access the policy responses that are considered to reduce alcohol consumption: alcohol taxation, legislative controls on alcohol availability, and age restrictions on alcohol purchasing, media information campaigns, school-based education, community action programs, and treatment interventions. Considering the influence of environments that people live in, effects of cultures and social norms that define the appropriate uses of alcohol. The value of population thinking in alcohol policy, and its ability to identify health risks and suggest appropriate interventions comparing different intervention strategies in terms of their effectiveness, and the ever-changing process that needs to constantly adapt to the evidence of new research results and tested intervention if it is to serve the interests of public health. One of the biggest determinants to alcohol consumption is the advertising and marketing of alcohol products by the drinks industry. The extent and the nature of alcohol marketing will be examined to illustrate its effects on consumption, cultures and social norms. We will show that more evidence is needed to progress education as a viable intervention. Showing evidence that the majority of the population, alter their damaging drinking through the phenomenon of spontaneous remission, maturing out or self change. It is good practice to learn from the past to plan for the future, the control of alcohol production, distribution, and consumption, has been around for thousands of years, such as requiring that all wine be diluted with water before being sold, these were devised by monarchs, governments, and the clergy to prevent alcohol-related problems. But it was not until the rise of modern medicine and the emergence of the world Temperance Movement in the 19th century that alcohol policy was first seen as a potential instrument of public health. Between 1914 and 1921, laws prohibiting the manufacture and sale of all or most forms of beverage alcohol were adopted in the United States, Canada, Norway, Iceland, Finland, and Russia (Paulson 1973). Most of these laws were repealed during the 1920s and 1930s, and replaced by less extreme regulatory policies. To view alcohol policies through the narrowly focused perspective of prohibition, however, is to ignore the fact that most policy-making during the past century has been incremental, deliberate, and respectful of peoples right to drink in moderation.: Alcohol control policies in public health perspective (Bruun et al. 1975), Sponsored by the World Health Organization (WHO), the monograph drew attention to the preventable nature of alcohol problems and to the role of national governments and international agencies in the formulation of rational and effective alcohol policies. Alcohol control policies stimulated a heated debate not just among academics, but also among policy-makers. The most significant aspect of the book was its main thesis: the higher the average amount of alcohol consumed in a society, the greater the incidence of problems experienced by that society. Consequently, one way to prevent alcohol problems is through policies directed at the reduction of average alcohol consumption, particularly those policies that limit the availability of alcohol. In the early 1990s, a new project was commissioned by WHO to review the development of the world literature pertaining to alcohol policy. The new study produced Alcohol policy and the public good, a book that proved to be as thought-provoking as its predecessor (Edwards et al. 1994). The book concluded that public health policies on alcohol had come of age because of the strong evidential underpinnings derived from the scientific research that had grown in breadth and sophistication since 1975. After reviewing the evidence on taxation of alcohol, restrictions on alcohol availability, drinking and driving countermeasures, school-based education, community action programs, and treatment interventions, it was concluded that: The research establishes beyond doubt that public health measures of proven effectiveness are available to serve the public good by reducing the widespread costs and pain related to alcohol use. To that end, it is appropriate to deploy responses that influence both the total amount of alcohol consumed by a population and the high-risk contexts and drinking behaviours that are so often associated with alcohol-related problems. During the past decade there have been major improvements in the way alcohol problems are studied in relation to alcohol policies. With the growth of the knowledge base and the maturation of alcohol science, there is now a real opportunity to invest in evidence-based alcohol policies as an instrument of public health. In 1994, Edwards and his colleagues provided a broader view of alcohol policy, considering it as a public health response dictated in part by national and historical concerns. Though there was not an explicit definition of the nature of alcohol policy, its meaning could be inferred from the wealth of policy responses that were considered: alcohol taxation, legislative controls on alcohol availability, and age restrictions on alcohol purchasing, media information campaigns, and school-based education, to name a few. Public policies are authoritative decisions made by governments through laws, rules, and regulations (Longest 1998). The word authoritative indicates that the decisions come from the legitimate scope of legislators and other public interest group officials, not from private industry or related advocacy groups. Based on their nature and purpose, alcohol polices can be classified into two categories: allocative and regulatory (Longest 1998). Allocative policies are intended to provide a net benefit to a distinct group or type of organization (sometimes at the expense of other groups or organizations) in order to achieve some public objective. The provision of treatment for alcohol-dependent persons is an example of a policy that seeks to reduce the harm caused by alcohol or to increase access to services for certain population groups. In contrast to allocative policies, regulatory policies seek to influence the actions, behaviours, and decisions of others through direct control of individuals or organizations. Economic regulation through price controls and taxation is often applied to alcoholic beverages to reduce demand and to generate tax revenues. Laws that impose a minimum purchasing age and limit hours of sale have long been used to restrict access to alcohol for reasons of health and safety. From the perspective of this paper, the central purpose of alcohol interventions is to serve the interests of public health and social well-being through their impact on health and social determinants, such as drinking patterns, the drinking environment, and the health services available to treat problem drinkers. Drinking patterns and behaviours that lead to intoxication, which leads to accidents, injuries, and violence. Similarly, drinking patterns that promote frequent and heavy alcohol consumption are associated with chronic health problems such as liver cirrhosis, cardiovascular disease, and depression. Alcohol is causally related to more than 60 International Classification of Diseases codes (Rehm, Room, Graham, and others 2003); disease outcomes are among the most important alcohol-related problems. 4 percent of the global burden of disease is attributable to alcohol, or about as much death and disability globally as is attributable to tobacco and hypertension (Ezzati and others 2002; WHO 2002). The conclusions for alcohol policy are the same, whether alcohol is the sole causal factor for or consequence, a causal factor among many others or a factor mediating the influence of another causal factor. In all cases alcohol contributes to social burden, and public policy must strive to reduce this burden, as well as the alcohol-related burden of disease. While there may be some offsetting psychological benefits from drinking (Peele and Brodsky 2000), from the point of view of minimizing the social harm from drinking, the general conclusion is that the lower the consumption, the better. The environmental determinants of alcohol-related harm include the physical availability of the product, the social norms that define the appropriate uses of alcohol (e.g., as a beverage, as an intoxicant, as a medicine), and the economic incentives that promote its use. Health and social policies that influence the availability of alcohol, the social circumstances of its use, and its retail price are likely to reduce the harm caused by alcohol in a society. Overall, the conclusion must be that alcohol consumption levels affect the health of a population as a whole. In addition to this, the predominant pattern of drinking in a population can have a major influence on the extent of damage from alcohol consumption. Patterns that seem to add to the damage are drinking to intoxication, and recurrent binge drinking. Another important determinant of health in relation to alcohol is the availability of and access to health services, particularly those designed to deal with alcohol dependence and alcohol-related disabilities. Alcohol-related health services can be preventive, acute, and rehabilitative, and can be either voluntary or coercive. Health policies have a major impact on the alcohol treatment and preventive services available in people within a country through health care financing and the organization of the health care system. Bondy S.J. (1996) Public health is concerned with the management and prevention of diseases and injuries in human populations. Unlike clinical medicine, which focuses on the care and cure of disease in individual cases, public health deals with groups of individuals, called populations. The value of population thinking in alcohol policy is in its ability to identify health risks and suggest appropriate interventions that are most likely to benefit the greatest number of people. The concept of population is based on the assumption that groups of individuals exhibit certain commonalities by virtue of their shared characteristics (e.g., gender), shared environment (e.g., towns, countries) or shared occupations (e.g., alcoholic beverage service workers) that increase their risk of disease and disability, including alcohol-related problems (Fos and Fine 2000). They also provide epidemiological data to monitor trends, design better interventions, and evaluate programs and services. In the context of the public good served by effective alcohol policy refers to those things that benefit most for a given society. One such public good would be effective intervention that would reduce alcohol related harm. Just as the eradication of malaria or (HIV) infections globally are seen as global public goods (Smith et al 2003). By locating alcohol policy within the realm of public health and social policy, rather than economics, criminal justice, or social welfare, Authorities tend to approach alcohol as a major determinant of ill health. Health is viewed not only as the absence of disease and injury, but also as a state in which the biological, psychological, and social functioning of a person are maximized in everyday life (Brook and McGlynn 1991). The way in which health is defined and valued within a society has important implications for alcohol policy. If it is defined narrowly as the absence of disease, then the focus is often placed on the treatment of alcohol dependence and the clinical management of alcohol-related disabilities, such as cirrhosis of the liver and traumatic injuries. If health is defined more broadly, then alcohol policy can be directed at proactive interventions that help many more people attain optimal levels of health. Health is influenced by a variety of factors, including the physical, social, and economic environments that people live in, and by their genetic make-up, their personal lifestyles, and the health services that they have access to. An attempt is made to synthesize what is known about evidence-based interventions that can be translated into policy. By comparing different intervention strategies in terms of their effectiveness, scientific support, generalism, and cost, it becomes possible to evaluate the relative appropriateness of different strategies, both alone and in combination, to present problems and future needs. As the scientific basis for alcohol policy begins to take shape, it is becoming apparent that there is no single definitive, much less politically acceptable, approach to the prevention of alcohol problems; a combination of strategies and policies is needed. If this realization is sobering, so too is the conviction, argued in this paper, that alcohol policy is an ever-changing process that needs to constantly adapt to the evidence of new research results and tested intervention if it is to serve the interests of public health. It will require extraordinary measures, some of them relatively painless to implement, others more demanding in terms of resources, ingenuity, and public support. Another important factor is the social norms of a society where there are important differences in the cultural meaning of drinking for men and women. Societies normative expectations regarding the use of alcohol vary across age groups and between men and women. In some societies, drinking has been almost exclusively a province of men (Roizen 1981), In many societies, abstention rates increase in the later stages of life for both men and woman (Demers et al. 2001; Taylor et al. 2007). This reflects social norms as older people are not suppose to get intoxicated and party as is common amongst young people. Most societies use taxation of alcoholic beverages to bring in revenue in larger or smaller quantities to relevant budgets. Alcoholic beverages are, by any reckoning, important, economically. The benefits connected with the production, sale, and use of alcohol come at an enormous cost to society. Public health specialists and policy-makers who forget this fact do so only at their peril (Edwards and Holder 2000). Also social customs and economic interests should not blind us to the fact that alcohol is a toxic substance. It has the potential to adversely affect nearly every organ and system of the body. No other commodity sold for ingestion, not even tobacco, has such wide-ranging adverse physical effects. Taking account of alcohols potential for toxicity is therefore an important task for public health policy. Especially the past decade, it can be said that remarkable progress was made in the scientific understanding of alcohols harmful effects, as scientists discovered biological, chemical, and psychological explanations for humans propensity to consume what has been called the ambiguous molecule (Edwards 2000). One of the biggest determinants to alcohol consumption is the advertising and marketing of alcohol products by the drinks industry. The extent and the nature of alcohol marketing have changed globally in the last decade, and the research has also expanded considerably to better understand its effects. Most of the new research is directed to the measurement of the impact of marketing on youth. More is now known about the effects of marketing on younger peoples beliefs and intentions to drink as well as on their drinking behaviour. Research has investigated the impact of marketing other than the broadcast and print media advertising, although some of the new media and marketing approaches being used by the alcohol industry remain unmeasured and under-researched. The first examination is the current state of alcohol marketing and what is known about the way in which marketing has its impact. Second, two different policy approaches codes of content and restrictions to reduce exposure are assessed for their likely impact on consumption and harm. Interventions that change exposure to advertising have often been limited and evaluations have mixed findings. More effort has gone into the establishment of codes aimed to affect the content of the advertising. Conclusions regarding the likely effects of these approaches can be made based on theoretical understanding and empirical evidence about the way in which marketing has its effects and its measured impacts. Conclusions may also be informed by research on tobacco advertising where the impacts are established and widely accepted (Lovato et al. 2004; Henriksen et al. 2008). The alcohol industry insists that they only advertise to promote their own particular brands, and that the advertising does not affect any rise in the consumption of alcoholic beverages. Research and evidence shows that the commodity chain analysis highlights the importance of advertising, sponsorship and other forms of marketing to a globalized alcohol industry (Jernigan 2006). The marketing of the products and brand(s) produced is essential for the profit-making enterprise. Marketing now involves much more than advertising using traditional media outlets such as print, television, and radio. Marketing exploits the possibilities provided by the design of products. New products and packaging have been developed to meet the needs and wants of different sectors of the market (Brain 2000). Pre-mixed drinks in which spirits or beer are made more palatable by the addition of a soft drink base or fruit flavourings have expanded in sales very rapidly and have become associated in some contexts, but not all, with heavier consumption (Huckle et al. 2008b). Packaging has increased acceptability and palatability of alcoholic beverages among young people (Copeland et al. 2007; Gates et al. 2007). It utilizes a range of new media opportunities including electronic means, and a key element is the sponsorship of sporting and cultural events. The measured media (usually broadcast and print) is known to be an underestimation of the marketing effort by a factor of two to four (Anderson et al. 2009b). Marketing at the place of sale has become increasingly important with an expansion of alcohol sales into more retail outlets. This often goes hand in hand with pricing promotions. For example buy-some-get-some-free (Jones and Lynch 2007). Promotion of alcohol brands in electronic media is a major part of marketing. Advertising is also shown in cinemas and this is increasingly supplemented by product placement in movies and television. Newer forms of electronic communication such as internet networking sites e-mail and cell phones have also provided new opportunities for alcohol promotion which are popular with young people (Jernigan and OHara 2004). Sports and cultural events, particularly those with appeal to young people, are widely sponsored by alcohol brands. They also provide opportunities for direct marketing through free gifts and exclusive pourage rights (Hill and Casswell 2004). Carlsbergs sponsorship of the EURO 2004 football/soccer championship was reported to grow the brand by about 6% worldwide; Carlsberg told shareholders that its signage had appeared in the background of television sport coverage for an average of 16 minutes per game (Carlsberg 2006). Much of marketing, including that based on sponsorship, crosses national boundaries. (Breen 2008). The theology is that the first stage is liking alcohol advertisements, followed by a desire to emulate the featured characters (including those that depict the lifestyle of young adults), and then the belief expressed that acting this way will result in positive benefits (Austin et al. 2006). Much of the marketing that targets young people is driven by an understanding of the importance of alcohol consumption for identity formation. The advertising is designed to provide humour, attractive ideas, images, phrases, and other resources that are used in the process of peer-to-peer interaction as identity is formed and communicated (McCreanor et al. 2005). The longitudinal studies have been subjected to systematic reviews. The strength of the association, the consistency of the findings, the temporal relationship, the dose-response relationship and the theoretical plausibility of the effect have led to the conclusion that alcohol advertising increases the likelihood that young people will start to use alcohol and will drink more if they are already using alcohol (Jernigan 2006; Smith and Foxcroft 2009; Anderson et al 2009b). Experience with policies to restrict the negative impacts of marketing is less well developed than with other areas of alcohol policy. In part this reflects the rapid developments and financial investment in marketing and media over the last four decades and a failure of policy developments to keep abreast of marketing practices. Research has suggested that voluntary codes are subject to under-interpretation and under-enforcement (Rearck Research 1991; Saunders and Yap 1991; Sheldon 2000; Dring and Hope 2001; Jones et al. 2008); including a bias in favour of the corporations represented on the decision-making board (Marin Institute 2008a). There are also documented cases of the instability of such voluntary codes in response to changing market conditions (Martin et al. 2002; Hill and Casswell 2004). Following the introduction of a co-regulatory approach in the UK, in which a government agency was delegated the handling of broadcast complaints to the Advertising Standards Authority (funded by the Alcohol industry), a code change was introduced. Research demonstrated that advertisements continued to contain attributes that appealed to young people and the data showed a link between exposure to advertisements and consumption of specific beverages (Gunter et al. 2008). This substantial body of research has shown that, even if alcohol marketing remains in line with codes on alcohol advertising content, it nevertheless encourages drinking and has an impact on younger peoples beliefs and alcohol consumption levels. A recent analysis of self-regulation by the alcohol industry in the UK concluded it was not an effective driver of change towards good practice (KPMG 2008b). Overall there is no evidence to support the effectiveness of industry self-regulatory codes, either as a means of limiting advertisements deemed unacceptable or as a way of limiting alcohol consumption (Booth et al 2008). Research has also suggested that the effects of marketing on beliefs about alcohol counteract any possible effect from health promotion activities (Wallack 1983; Centre on Alcohol Marketing and Youth 2003). Recipients, who bring their own cultural and social experiences to their interpretation of the marketing, may perceive heavy drinking or intoxication as represented within the advertising even when it is not shown directly (Duff 2003; McCreanor et al 2008). This is particularly likely to have an impact on efforts to reduce heavier drinking as a cultural norm. Direct effect on exposed individuals is not the only concern which underpins restrictions on marketing, however. It is possible that widespread marketing, which promotes alcohol as a positive and commonplace element of everyday life, has an impact on social norms around alcohol which may, in turn, affect the acceptability of more restrictive policies and practice. In effect, marketing is a force for ensuring that alcohol is dealt with as if it were an ordinary commodity (Casswell 1997). There is clearly a need for an independent review of the evidence, with a view to impose restrictions that can meet public health goals. In some jurisdictions there are restrictions, typically by regulation, on exposure to alcohol marketing by media type, beverage type, time of broadcast or composition of media audiences (particularly of younger people). Most research has focused on exposure of young people to the measured media. This varies by country. In the USA, young people aged 15-26 years on average reported seeing the equivalent of almost 360 advertisements per year, the majority on television. Restrictions imposed by agreement among industry actors are inherently unstable. In the context of the EU and other trade agreements, they may be subject to legal attack as an illegal restraint of trade. They may also be easily breached or dropped. The effect of partial bans was also reported not to have affected consumption in seventeen countries over 26 years (Nelson 2008a), in a study with material that included at least fifteen consequential changes in bans. A comprehensive regulation of alcohol marketing, and one which has maintained political support for more than a decade, one of the key elements of the Loi Evin (relevant to the need to control the current ongoing proliferation of marketing approaches) is that advertising of alcohol is prohibited in all media unless the law provides for an exemption; there is a complete ban on sponsorship and on advertising in many media, including television and cinema. Such advertising regulation has been challenged. However, restrictions on alcohol advertising to meet public health goals have been upheld by the courts, although sometimes with some modification. However, the findings of an effect of exposure to marketing put the question of controls on advertising high on the policy agenda. The extent to which effective restrictions would reduce consumption and related harm in younger age groups must remain somewhat of an open question. The most probable scenario, based on the theoretical and empirical evidence available, is that extensive restriction of marketing would have an impact. The evidence suggests there can be other effective restrictions other than advertising, strategies such as availability can have an effect studies of restriction on alcohol availability support the conclusion that such strategies can contribute to the reduction of alcohol problems. The best available evidence comes from studies of changes in retail availability, including reduction in hours and days of sale, limits on the number of outlets and restriction on retail access to alcohol. For young people, laws that raise the minimum legal drinking age reduce alcohol sales and problems. This strategy has the strongest empirical support (Shults et al 2001; Wagenaar and Toomey 2002), with dozens of studies finding substantial impact on traffic and other casualties from change of the drinking age. The cost of raising the drinking age is low, and as the evidence shows that in the USA they estimated that thousands of lives have been saved over the last decade (Wagenaar et al. 1998). A WHO analysis of the relative cost of a restricted access option estimated that Saturday closing would have considerable societal benefits in most parts of the world, though that would still be less than the result from a substantial price rise in alcohol via taxation.(Chisholm et al. 2006; Anderson et al. 2009a) This provides evidence that regulations backed up with enforcement can be effective in reducing alcohol consumption and problems; this is also used to force all sellers to hold a specific license to sell alcohol beverages, if there is any sales infringements the license can be suspended or revoked. As well as restrictions and regulation strategies, measures to reduce the harm in drinking situations are thus a useful option in the mix of strategies for preventing, alcohol-related problems. The less the political process is willing to support general alcohol control and tax measures the more important local harm reduction measures become. Alcohol policies are primarily the concern of local, regional, and national governments, which often view the provision of treatment as part of a comprehensive approach to alcohol-related problems. In addition to its value in the reduction of human suffering, treatment can be considered as a form of prevention. When it occurs soon after the onset of alcohol problems, it is called secondary prevention; when it is initiated to control the damage associated with chronic drinking, it is called tertiary prevention. As one of the first societal responses to alcohol problems, treatment interventions have not been critically examined as policy options, despite the resources they consume and the scientific evidence that is available concerning their effectiveness and costs. To what extent are alcohol treatment and early intervention services effective in reducing population rates of alcohol-related harm? Other questions relevant to treatment policy include the following: Should people with these conditions be managed within the general health care system, specialized addiction services, social welfare agencies, psychiatric facilities, the criminal justice system, or a combination of these entities? What is the optimal amount and best combination of services needed to serve the needs of a country or a geographic area? What kinds of treatment systems are best suited to prevent the marginalization of people with chronic alcohol problems? How can treatment services best be organized to provide the most effective treatment at the lowest cost? Treatment for alcohol problems typically involves a set of services, ranging from diagnostic assessment to therapeutic interventions and continuing care. Researchers have identified more than 40 therapeutic approaches, called treatment modalities, which have been evaluated by means of randomized clinical trials (Miller et al. 1995). Examples include motivational counselling, relapse prevention training, marital and family therapy, aversion therapy, cognitive-behavioural therapy, pharmacotherapy, and interventions based on the Twelve Steps of Alcoholics Anonymous. These modalities are delivered in a variety of settings, including residential facilities, psychiatric and general hospital settings, outpatient programmes, and primary care. More recently, treatment services in some countries have been organized into systems that are defined by linkages between different facilities and levels of care, and by the extent of integration with other types of services, such as mental health, drug dependence treatment, and mutual help organizations (Klingemann et al. 1993; Klingemann and Klingemann 1999). Most treatment research and the scientific evidence derived from it are component-based, focusing on a single intervention or episode of care. In general, the research, evidence can be organized according to three types of intervention within the emerging treatment systems of countries where information on efficacy and effectiveness is available, interventions for non-dependent high-risk drinkers, formal treatment) for problem drinking and alcohol dependence, and mutual help interventions. Harmful drinking typically precedes the development of alcohol dependence, and by definition it can cause serious medical and psychological: problems in the absence of dependence. With the increased interest in clinical preventive services in both developed and developing countries, early intervention programmes have been developed by WHO and national agencies to facilitate the management of harmful drinking in primary health care and other settings Interven

Personal Narrative- The Dieting Cycle Essay -- Personal Narrative, ess

It was about 1:30 AM. "Well, its time to hit the sack," I thought. I had had a really long day. I had been in school since 8 AM and I was truly exhausted. God I hated Mondays! Three classes, four hours of work, and then a night class where even the walls attempted to escape the boredom of the lectures. I wondered how I was able to do this every week. I laughed and thought, "I must have a lot of patience..." I quickly changed into my favorite pajamas - sweats and a tee- and I began to brush my teeth. As I washed my face to eliminate the dirt and grime of a hard days work, I caught myself staring into the mirror. I said to myself, "Gosh, I look horrible today." My hair seemed so dull, so bland. My face looked so pale, so white. My eyes were surrounded by a purplish blue coloring, the same coloring that I had attempted to hide that same morning with my makeup. My eye lids felt like they weighed a ton. "Damn! Mondays are really starting to wear me down. I got to start getting some rest." But that was not it, and I knew it. I lied to myself so that I would feel at ease and calm, but deep down inside I knew why I looked the way that I did. It wasn't my hectic schedule and it wasn't the lighting of the mirror. It was my relentless battle that I fought day and night with no chance of victory. As I entered my bedroom, I immediately pulled down the covers and laid my body to rest. My spine hit hard against the rings within my mattress and I was in pain. "Ouch! That hurts like hell! When am I finally going to get a mattress that is actually soft and comfortable and that doesn't dig into my back." But the mattress wasn't the problem. I had used that mattress for years and it never once gave me a problem. But now things were diff... ... was now past 2:00 AM. I had wasted more than half an hour walking to and from the kitchen debating whether or not I should or should not eat. This was ridiculous. "Tomorrow I start fresh," I said. I will eat lunch and dinner. I will start trying to get my life back together. I felt at ease and was comforted by the thoughts of living a normal life again. Deep down inside, however, I knew damn well that tomorrow would be no different than today. I knew that I would start the day worrying about how I looked and how much weight I had gained. Then I would spend the day dieting and not eating a thing. Then at night I would flip out and tell myself that I would try harder the next day to make things right. It was an endless cycle that just went on and on. I prayed that it would stop, but I feared that it was too late. I had gone too far and now there was no turning back.

Body Language :: essays research papers

What is Body Language?Definition: Body Language is communication through gestures or attitudes.

We retain vivid images of facial expressions and body behavior.Body language usually dose not lie. We can build trust with our students by showing them that our actions will be in sync with our words.Alert teachers watch their students' movements, actions, and emotions and use what they see to adjust their teaching methods to be effective with their l essons.By being alert to student behaviors, teachers can more easily predict and deter inappropriate behavior before it becomes a problem. Teachers need to be able to control their own body language so they can be in charge of the message they want to portray to the students. They can send out positive body language messages to promote positive interaction between her/himself and the students and between students and other students.Modeling positive body language is important because body language can be very contagious.Issues that contribute to one's use of body language:culture physical size gender mood past experiences age position Examples for the classroom:</bAlways observe the students' body language and be able to detect boredom. By being alert to students' body language messages you are more likely to meet their needs and interests even if they may not verbalize them. Use direct eye contact with your students. This is one of the most important nonverbal teaching skills. L ook directly at the student (not at their hair, shoulder, what they are wearing). Looking any place else is too distracting for them. Do not make it a habit to stay behind or around your desk all of the time. Whether they realize it or not, some teachers use their desk as a wall of protection or symbol of authority in the classroom.

A Looking Glass Fogged :: Journalism Journalist Essays

A Looking Glass Fogged In reporting, it is sometimes the case that a story is told from a certain point of view due to political pressures, especially when dispute surrounds the subject matter. One such case is the reporting on the Chinese-Tibetan conflict, in which China's overwhelming political and fiscal power has the potential to seep into the affairs of newspaper owners. In my paper, I will examine a certain event as it was published in a variety of newspapers, and how their coverage differs from the AP Worldstream report. Additionally, I will analyze what appears to be an extremely one-sided report and how it is of benefit to its publisher. China has always sought to culturally integrate Tibet with the Chinese mainland, for reasons as diverse as the parties involved. Recently this has expressed itself in the form of a planned railway reaching from Beijing to Lhasa, the Tibetan Capital. China has justified this action with its usual stance on Tibetan integration, as an effort to modernize Tibet 'for its own good' and provide it with an influx of labor and industry. Groups opposed to the project fear that the railway will cause a new wave of Chinese settlers who will dilute the region's unique culture and exploit the land for its resources. (AP-Worldstream) The Associated Press is a news source for news sources. Their business consists of covering events and reselling the reports to a variety of papers, so it is in their interest to stay as neutral as possible. In their coverage of the Railway project they cover both sides equally, starting with China's moral obligation to "enrich" the Tibetan culture with an inflow of Chinese culture and labor. To quote Shi, an overseer: "Tibet has been without the railway, but now they will have the same great things and great life as us."(2) While the Chinese side makes no mention of this, the AP report covers political motives for this $3.3 billion investment. With the railroad in place, China would be able to immediately deploy troops to stomp any sort of Tibetan uprising as well as saturate the area and culture with Chinese immigrants, furthering China's grip on the Tibetan region. The article does a thorough job of showing both unrelenting sides of the issue - the Chinese developer's zeal for get ting the railroad underway and wants for further development, employment and opportunities, and the Tibetan fear of exploitation and cultural dilution.

Women in an Inferior position in China

The view of women in china may have changed over the years but they all have lived in a male dominated world. The past has been like many cultures, in the legal and cultural suppression of women. The culture of china's past has placed women as a far inferior position to men. In this environment gaining power and rights was extremely difficult. Despite this there are stories of important and powerful women in china's history. This is different than many cultures of the world where the suppression of women's rights was total through their history. The culture has become more open to women's rights over the years, allowing for more power and more control for them as they years went on. Education has slowly been allowed along with greater human rights. Modern women are allowed to travel, be educated, marry and be the sole wife. They commonly participate in politics, as well as all other fields of work. Women of modern times in china have greater possibilities and fewer limitations, but things are not perfect, there is still a social bias lingering from past inequality. The women of china's past lived in an intensely male dominated world. Men dominated china both in law and in culture. Legally women were in servitude to men in the forms of marriage polygamy was common practice for men. For the most part women did not ever participate in the governing of the country. There were Dynasties that were less conservative, women were allowed more power at times. This is evidenced by the rule of Empress Wu. She rose to power from the status of concubine to rule china. This was more exceptional rather than the rule. When the Sung dynasty took over, men dominated again. Any ability of women to gain political power was taken away. It is in the culture that the real domination can be seen. Without this the legal repression would not have happened. Many practices reinforced the view that women were inferior. From basic philosophy, Yin and Yang, equated, darkness to women and light to men. The beliefs of Confucianism said that women weren't meant to do outdoor work, thus construing them as weak and inferior. The idea of having them not do outdoor work was reinforced by the practice of foot binding. Again started in the Sung dynasty, this practice along with the other preferences on the appearance of women objectified them and put barriers on what women could do or be. Women were seen as property, as seen by the practice of concubines and polygamy those of high status had many women and having many sons was an even higher symbol of status. Despite these legal and cultural blocks on women, the domination was not total. There were many female figures that were looked up to and honored, both legendary and real women. At times the culture changed enough to allow women to participate in politics, and more rights were given to them. Powerful women of the past were looked up to and revered. The Queen Mother of the West was mixed with legend and history, but she was worship at times by men. Other legends indicate that women could be respected. Although Disney has probably distorted it a bit, the legend of Mulan even by being passed down shows a respect for women. Not only legends were respected. There were several times in the past that women have risen to power Empress Zhen (AD 182) was fought over and had power through her beauty and high status. Other women had even more power, Empress Wu, actually had power, and ruled china for a time. The culture of china's past has surpressed women, through it's culture and laws, with brief periods of cultural change, in which women gained rights and respect were brief and followed by periods which they were again taken away. These limitations on women, were reinforced by the isolation that china had, continuing into the twentieth century this isolation prevented women from leaving if they could not stand their situation. Despite the few legendary women the opportunities for advancement or power for women were few and difficult. Things have changed in recent times. Women are gaining power and rights in modern times. There are international groups protecting their rights as well. The first good example of this is in the ways of marriage. Arranged marriages, and those for money are no longer the norm. They are allowed to maintain their own names with marriage. Without this they are did not have as much of a separate identity. Also in modern times, women have gained the rights of inheritance from their families, equal to that of their brothers. Other aspects of women in marriage have changed. They are not as expected to bear children, and the culture is changing to give them a voice in this decision. In the areas of employment, there are opportunities as well. Women now make up 38 percent of the total workforce. In most major parts of the work force women play a part. Women even play a part in politics, representing a major part of their official government. These women are not legendary, or exceptional. It is just accepted and considered normal. Women have made advances in the field of education as well. Illiteracy among women has fallen as well and education is accepted. Women are allowed in universities and even given funding to continue education. These opportunities, encouraged by many international organizations are also backed by Chinese law. The law states: 1.Equal rights for men and women. The Constitution stipulates that â€Å"Women enjoy equal rights with men in all spheres of life, political, economic, cultural and social, including family life†; 2.Protection of special rights and interests of women; and 3.Banning of any discrimination, maltreatment and persecution directed at women. In addition Other laws have been enacted concerning their rights. These explicitly state aspects of life that women are equal to men. For example equal, equal votes, and rights to political power, freedom, and protection. These laws being stated are the only thing that I can see evidencing that there are not equal opportunities for women. The fact that they have to be stated so explicitly probably indicates a problem. It is difficult to find out what the cultural views of women are from the outside, but it appears that they have all the major opportunities that men do and that their power is increasing. One thing that has really changed is in the area of the world. There is the opportunity to leave the country and go to another culture. Granted the rest of the world is still mostly male dominated in culture, but the opportunity to emigrate is still there. The only lingering restrictions are from tradition. Lingering views of women as being inferior are probably the only thing that could keep them back now. These things can be seen through the increasingly seldom seen practices of mail order brides and foot binding. In addition, I came across a large industry of pornography featuring Chinese women when searching for information. These things limit the respect that women have in society. The opportunities for women have grow through history. Starting from the possessive view of women, giving them no rights, and giving men utter control, has changed in recent history to the to allow women more power, rights and education. Women have had their limits striped away, partly with law and partly through changing culture. The physical limitations have gone as well. The opportunities for travel have grown as well, the world is more open, and the ability to find a place more accepting exists. With fewer limitations, opportunities for women are increasing.

Benefits of Medical Marijuana Essay

Marijuana is perhaps one of the most controversial herbs rendered illegal by United States laws. Several sectors in the society advocate for the legalization of marijuana. These arguments usually point out to the medical benefits that marijuana contains. The supposed medical benefits of marijuana have been scrutinized by several scientific researchers and some of these claims have been supported by studies. By looking objectively at these medical claims can help people be more aware of the facts and the actual benefits that marijuana offers if there are any. Medical Benefits of Marijuana Medical marijuana, according to some studies can help relieve pain, nausea and muscle spasms. Although these illnesses may be simple symptoms of more serious diseases, they are being experienced by a number of patients that are suffering from hepatitis and cancer among others. In this regard, medical marijuana can be a cheaper alternative for the treatment of these medical conditions (Legal Reefer, 2004). Another medical condition that marijuana can help treat is glaucoma, which impairs the vision because of intra-ocular pressure damage. The reason behind this is that marijuana helps relieve the pressure felt in the eyes, thereby preventing glaucoma from worsening and leading to eventual blindness. Glaucoma, interestingly, is the leading cause of blindness in the United States. With the use of marijuana, therefore, this cause of blindness can be mitigated and more people can cherish their sight for a longer time in their lives. Glaucoma and the pain associated with it can be relieved with marijuana (Legal Reefer, 2004). Other illnesses that marijuana helps treat includes tremors, unsteady gait, muscle pain, multiple sclerosis and spasms. Multiple sclerosis is one of the most debilitating neurological illnesses that afflict young adults in the US. With the help of marijuana, those who are suffering from epileptic seizures also find help. Arthritis, dysmenorrheal, depression and migraines also benefit from treatment with marijuana. The Legal Reefer (2004) reports that some courts and agencies of the US government have verified these findings. Two compounds, Cannabidiol and Caryophyllene, are present in medical marijuana. These two compounds are responsible for the medical effects of marijuana. Cannabidiol helps relieve inflammation, nausea, inflammation and convulsion (Grlie, 1976). In addition, it also helps inhibit the growth of cancer. Caryophyllene, on the other hand, is responsible for reducing tissue inflammation. It usually comes in the form of oil and applied on the inflamed body part (Grlie, 1976). Even if the issue of legalizing marijuana is contentious in the United States, medical practitioners are coming to a consensus that medical marijuana is needed helpful in relieving up to 250 medical conditions. This number is too huge to be ignored by the greater majority in the society. Legalizing Marijuana The literature in support of medical marijuana is robust and continues to grow. Medical marijuana has been shown to aid in the treatment of symptoms for AIDS and cancer. It can also serve as an immuno-modulator and analsgesic. Furthermore, it can help treat asthma and other emotional and bipolar disorders (Lucido, 2008). The American College of Physicians (2008) have also come up with a position paper in support of research concerning medical marijuana and the exemption of medical marijuana from the prosecution of the law. In their paper, the organization cited the health benefits of marijuana in stimulating appetite, in treating glaucoma, neurological and movement disorders and its use as an analgesic. The position of the ACP gives credence to the claims that marijuana can really function as a good medicine. The ACP, however, noted that there are adverse effects associated in marijuana. If smoked, marijuana can increase the heart rate of the user and help decrease the blood pressure. In addition to this, there are other psychoactive effects that are of a more serious nature. These may be manifested in short-term memory impairment, reduction of motor skills, attention and reaction times. There may also be some difficulties in organizing and processing information given to the one who used marijuana. These effects are more severe for those who orally take medical marijuana. So this is certainly an adverse effect that should be carefully taken into account in the case that marijuana is approved as a medicine (Joy, Watson & Benson, 1999). Smoked marijuana also has important adverse effects similar to tobacco. If marijuana is smoked on a regular basis, it can help induce cancer, lung problems, pregnancy problems and even bacterial pneumonia. When taken orally, medical marijuana has less lethal toxicity than other psychoactive drugs being used in the world today. Since medical marijuana will not be prescribed for smoking, then the dangers posed by the adverse effects will be mitigated and will be contained. In fact, these adverse effects are also within the acceptable range of effects present in other forms of medication. Marijuana: To Legalize or to Remain Illegal? With the support of the ACP for the continuation of research for the medical implications of marijuana. With such support, the impetus for legalization will be picked up by those who are advocating for the legalization of marijuana. Another reason why people are pushing for the legalization of marijuana is the perceived economic benefits that it will bring to the government. Marijuana has often been compared with alcohol, which also have harmful contents but is being allowed to be marketed all over the country. If the government could legalize it, then it can derive huge revenues from the taxes and sales derived from marijuana. As it stands now, it is illegal. So the ones who benefit from the marijuana trade are the black market and organized criminals (Gerber & Sperling, 2004). Marijuana is similar to alcohol and tobacco. The major difference is that marijuana offers therapeutic and medicinal effects while tobacco does not and alcohol only helps enhance health minimally. According to Herer and Cabarga (1998), those who are getting rich through the black market want it to remain illegal because if it becomes legal, the money will then have to be transferred to the hands of the government. Conclusion What is needed now is to strike the right balance between maximizing the medicinal effects while mitigating the negative effects of marijuana. The answer to the question of legalization would be a controlled legalization. Marijuana could be used for medicinal purposes and alternative treatment. This means that it would have to be recommended by licensed physicians and that there should be a regulation in using it in the same way that certain narcotic pain killers are regulated in the market. Marijuana should not be offered as an over-the-counter medicine or offered like tobacco or alcohol as this would only make the negative effects of marijuana more prevalent in the society. With government legislation and strict implementation of the law, the medicinal values of marijuana would be used by society while its negative effects would be avoided.
