Socrates-Trial and Death free essay sample

A discussion on the trial and death of Plato as depicted by Plato. This essay examines the trial and death of Socrates as shown by Platos Apology and The Crito. The trail of Socrates was not so much against the individual as against the intellectual class. It took place at a time when Athens had been defeated in war and the moral of people was low. The state needed a scapegoat who could be punished as a cause of the defeat. Thus, Socrates then represented the intellectuals who had begun questioning the state and thus, had to be suppressed in authority was to be held in the traditional manner. At his trail in The Apology Socrates had asked what morality was but was given no definite answer. In The Crito as he awaits death he suggests that morality explores the concept of the good things in life and is the determining factor in the happiness of the human life.

Cloze Tests to Determine Reading Comprehension

Cloze Tests to Determine Reading Comprehension When teachers wish to measure how well a student comprehends a reading passage, they often turn to Cloze tests. In a Cloze test, the teacher removes a certain number of words that the student then needs to fill in as they read through the passage. For example, a language arts teacher might have their students fill in the blanks for the following reading passage: _____ mother is upset with _____ because I got caught  _____ a rainstorm. Sadly, I ______ my umbrella at home. _____ clothes got soaked. I ______ I wont get sick. Students are then instructed to fill in the blanks for the passage. Teachers are able to use the student’s answers to determine the reading level of the passage. Why Readability Formulas Are Not Enough While readability formulas can tell teachers how complex a reading passage is based on vocabulary and grammar, it does not reveal how difficult a passage might be in terms of reading comprehension. For example: He waved his hands.He waived his rights. If you were to run these sentences through readability formulas, they would have similar scores. However, it is obvious that while students might easily understand the first sentence, they might not comprehend the legal implications of the second. Therefore, we need a method to help teachers measure how difficult a particular passage is for students to comprehend. History of the Cloze Test In 1953, Wilson L. Taylor researched closure tasks as a method to determine reading comprehension. What he found was that having students use context clues from the surrounding words to fill in the blanks as in the example above has a high correlation with how readable the passage is for the student. He called this procedure a Cloze Test. Over time, researchers  have tested the Cloze method and found that it does indeed indicate reading comprehension levels.   How to Create a Typical Cloze Test There are a number of methods that teachers use to create Cloze tests. Following is one of the most common methods used: Replace every fifth word with a blank. This is where the students are to fill in the missing word.Have students write only one word in each blank. They are to work through the test making sure to write a word for each missing word in the passage.Encourage students to guess as they go through the test.Tell students that they do not need to worry about spelling errors as these will not be counted against them. Once you have administered a Cloze test, you will need to ‘grade’ it. As you explained to your students, misspellings are to be ignored. You are only looking for how well students understood what words to use based on contextual clues. However, in most instances, you will only count an answer as correct if the student answers with the exact missing word. In the example above, the correct answers should be:   My mother is upset with me because I got caught  in a rainstorm. Sadly, I left my umbrella at home. My clothes got soaked. I hope I wont get sick. Teachers can count up the number of errors and assign a percentage score based on the number of words that the student guessed correctly. According to Nielsen, a score of 60% or more indicates reasonable comprehension on the part of the student. Using Cloze Tests There are a number of ways that teachers can use Cloze Tests. One of the most effective uses of these tests is to help them make decisions about reading passages that they will be assigning to their students. The Cloze procedure can help them determine what passages to assign students, how long to give them to read specific passages, and how much they can expect students to comprehend on their own without additional input from the teacher. Note, however, that Cloze tests are diagnostic. Since they are not standard assignments testing a student’s understanding of  the  material that has been taught, the student’s percentage score should not be used when figuring out their final grade for the course.

Discuss how â€Å"The Banquet Scene† has been realised on screen and consider the effectiveness of its portrayal. Shakespeare was born in 1564 when Elizabeth the First was Queen of England. Shakespeare did not go to university when he left school; instead, he worked. He married Anne Hathway when he was eighteen and she became the mother of his daughter, Susanna, and also of twins. Although there are many public documents concerned with his career as a writer and a businessman, Shakespeare has hidden his personal life from us. A nineteenth century poet, Matthew Arnold, addressed Shakespeare in a poem and wrote: â€Å"We ask and ask – Thou smilest, and art still†. There is not even a portrait of the world’s greatest Dramatist. I am going to look at the banquet scene, in my opinion, one of the most important scenes in â€Å"Macbeth†; it shows many sides to both Macbeth and Lady Macbeth. The scene opens with the couple welcoming all the guests to their Banquet, the atmosphere is warm and jolly, and everyone is joking and enjoying themselves. The atmosphere becomes more sombre when one of Banquo’s murderers arrives with news for Macbeth. Although Banquo is â€Å"safe†, Fleance on the other hand has † ‘scap’d â€Å". Macbeth tries to â€Å"Act like the innocent flower, but be the serpent under’t† in front of his guests, but this does not last for long, the guilt gets the better of Macbeth and causes him to hallucinate. The Lords were all very confused, and so, Lady Macbeth tries to cover-up for her husband by telling them all that Macbeth suffers from an illness, which causes him to behave in such a manner. â€Å"Sit, worthy friends – My Lord is often thus, and hath been from his youth†. â€Å"The fit is momentary – upon a thought he will be well again†. The two productions I am going to look at are Roman Polanski’s 1971 Production along with Gregory Doran RSC production. In Gregory Doran’s production, Macbeth’s house resembles a prison. The front foyer is very bare, with lots of different entrances: this is trying to show us that Macbeth is imprisoned in his world of guilt. Macbeth is dressed as a soldier, which gives me the impression he is at war, maybe Doran is trying to put across the fact that Macbeth is trying to fight against all of the evil. Roman Polanski dressed Macbeth in beautiful robes; Macbeth is also wearing his crown. This makes me think Macbeth is in total control of everything. Both producers hold the Banquet in a large, dull, cold room, this symbolises the fact that Macbeth has nowhere to hide; it also creates a tense atmosphere. In Polanski’s production, Macbeth sees Banquo and he goes mad! â€Å"Avaunt! And quit my sight! Let the earth hide thee!† He continues to rant and rave at this ghost of Banquo, whom only Macbeth can see. He frightens and startles not only the lords, but also Lady Macbeth. We know this by the look of worry on her face. She then pulls her husband aside to try and help him see sense. He sees what she is trying to say and returns to normality, but this only lasts for a matter of moments, and then Macbeth resumes to his fit of madness again. Macbeth is gradually loosing control. While Macbeth moves back, Banquo continues to advance. As both men keep moving, the camera becomes Banquo. We see high angle shot of Macbeth; it seems as though Banquo is looking down upon Macbeth and that he is now the one in control. Lady Macbeth tries to make excuses for her husband’s behaviour by saying â€Å"Sit worthy friends: My lord is often thus, and hath been from his youth: pray you, keep seat: the fit is momentary: upon a thought he will be well again†. We then see a long shot of the lords at the table; they all look very puzzled and confused. By this time, Macbeth is in a corner, on the ground with Banquo towering over him, he moves in closer and closer, then Banquo is cut, and Macbeth is left sitting on the ground, a trembling wreck. Gregory Doran’s RSC Production is very similar to Polanski’s. He also shows Macbeth being overpowered by Banquo. When Lady Macbeth pulls Macbeth aside to try and snap him out of his â€Å"fit†, he is unable to look her in the eye, he keeps watching the ghost of Banquo. He realises what his wife is trying to say, and so he returns to his normal self again. The way that Macbeth is changing personalities so suddenly in this scene reminds me of a schizophrenic, it’s almost as though he has some kind of mental disorder. Macbeth tries to laugh it off and composes himself. However, this only lasts for a moment. When Macbeth sees Banquo again, he drops his chalice, and the white wine spills onto the floor. This is an interesting observation because all the other products I watched used red wine, a sign of evil and danger, but white reminds me of innocence. Maybe Gregory Doran feels that Macbeth was innocent and this is why he uses white wine rather than red. He may feel it was the witches, or maybe Lady Macbeth’s influence that encouraged him to do all those evil things. Personally, I feel it was Lady Macbeth that caused him to go through with Duncan’s murder, but yet again, how many could be talked into murder without desiring it themselves? Act 3, Scene 4 provides a great opportunity for visual spectical. (2017, Oct 14).

Explain the difficulty in accounting for service trade versus tangible Essay

Explain the difficulty in accounting for service trade versus tangible goods in the Balance of Payments (BOP) framework - Essay Example Therefore, such transactions may not be reported, recorded, or even traced. As opposed to physical goods, the valuation of services is considered to be a difficult task as there may not be a single basis for measuring them and different companies within a single country may be using different approaches to recording of financial data. It is also impossible to deliver the same service or standard of service to customers which may create an argument that services may not recorded on a standardized manner (Arnold, 2011). It is also understood that the valuation of financial services including derivatives can have varying effects on balance of payments of different countries as they are based on different bases of measurement. Furthermore, there may be lacking of benchmarks which can be used for recording and measuring of services. Therefore, it is impossible to include all items of services in the current

Humanities - Essay Example As the paper outlines arts played a major role especially in the urban society leading to a progressive and dynamic growth. With growth, intellectual innovations and spiritual tensions in the Church there emerged new and creative styles in architecture, visual arts, literature and music. The three relationships of art during the Middle Ages that I would like to discuss with my students would be on architecture, literature and music. On the architectural front, an artistic renaissance emerged and was supported by both religious and secular patrons. Islamic and Byzantine civilizations created an impact resulting in Romanesque architecture that involved magnificent cathedrals with round archways and intricate stone carvings. Following this was the Gothic architecture with its flying buttresses and vaulted ribs such as used in the Notre Dame in Paris. Secondly, Literacy flourished during the Middle Ages. Latin was the dominant language in which many books were written but were also trans lated into other languages such as English, German and French. Lyrical poetry played an important role by celebrating the love between knights and ladies in the court. Epic tales of chivalry, love and heroism were exemplified in wonderful literary works such as ‘Beowulf’, Sir Gawain and the Green Knight and Canterbury Tales. Enlightening literature on Religion on the biographies of saints and their miracles were beautifully drawn and painted on handwritten manuscripts in gold and other brilliant colors. Thirdly, during the Middle Ages, music was considered to be an integral part of their lives and as it evolved, it increased in complexity with the monophonic Gregorian chant and interesting ballads that involved the complex weaving together of polyphonic musical lines.

Hybrid Electric Cars, Combustion Engine driven cars and their Impact on Environment Essay Fig. 1. Estimated grows of Planet Earth Population But the expected grow of automobiles will grow much rapidly. The growth will be caused mainly with inevitable living standard improving in many countries like Africa, South Asia and South America together with enlarging of population in these regions. The estimated grows of automobiles over whole Earth is shown in Fig. 2. From comparison of both figures results that the population may grow between years 2000 to 2050 from 6 to 10 milliards that means 1. 7 times, but the expected vehicle number will grow from 0. 7 to 2. 5 milliards that is 3. 6 times.

Total world production of CO2 These problems are so serious that they became very important theme of international discussions. Results of these discussions were settled in the Kyoto Protocol. Kyoto Protocol is an agreement made under the United Nations Framework Convention on Climate Change (UNFCCC) Automobiles produce approximately a half of the total world production of CO2. Let us imagine that a good new car produces approximately 160 g of CO2 pro each km. There are many possibilities how to diminish this terrible amount. Electric hybrid cars are produced in enlarging numbers and they reach enlarging popularity between customers. They bring a new possibility how to diminish the world CO2 production. II. ELECTRIC HYBRID CAR SYSTEMS Hybrid electric vehicles combine electric and internal combustion engine drive. Hybrid electric vehicles combine the zero pollution benefits of electric motors with the high fuel energy density benefits of the thermal engine. Hybrid electric drives adjust the combustion engine load and revolutions into the point of best motor efficiency and lowest motor emissions. [1], [4], [6], [7]. A. Basic Drive Configurations Series hybrid drive in Fig. 4 presents a combination of different energy sources. In the picture the energy sources are the combustion engine and the battery. The internal combustion engine ICE propels a generator. Total power in form of the generator electric power and the battery electric power are summed in the traction motor. There is no mechanical connection between ICE and wheels. internal combustion engine generator ICE gear box GB battery traction motor TM BAT ICE Fig. 5 Parallel hybrid drive G battery Combined switched hybrid drive in Fig. 6 is based on series hybrid drive with mechanical coupling using a clutch between generator and traction motor. It is series hybrid drive when the clutch is off. BAT traction motor internal combustion engine ICE TM generator G battery BAT coupling Fig. 4. Series hybrid drive Battery acts as energy buffer. Advantage of series hybrid drive is the possibility to operate the thermal engine ICE in optimal revolutions quite free from the car velocity. That results in low specific fuel consumption and in low gas emission for any traction load and car velocity. Efficiency of energy conversions in the system must be taken in account. Parallel hybrid drive in Fig. 5 is a combination of ICE and electric traction motor on the same shaft. Traction motor is supplied by battery and its output is separated from the ICE output. Final traction torque is sum of both motors torque. Power transmission is more effective than in series hybrid drive because the mechanical ICE output is not transformed in electrical output. But the ICE cannot work in optimal load regime because its speed is not free from the car velocity. traction motor internal combustion engine TM Fig. 6. Combined switched hybrid drive The generator supplies the electric energy to the traction motor. When the car speed and ICE speed and power are high but the difference between ICE speed and car speed is small, it is better to operate the scheme as parallel hybrid drive and the clutch is on in such a case. On this regime the ICE power and speed are high and the ICE can operate with small output changes. The difference between desired traction output and ICE optimal output is stored in or discharged from the accumulator. The drive is depicted in Fig. 9. It consists with gasoline engine, double rotor DC generator, and traction motor. traction motor Combined hybrid with planetary gear in Fig. 7 is a topology where mechanical power splitting is used. The splitting is performed in the planetary gear. In this scheme the generator rotates with speed, which is difference between the ICE and car speed. This solution allows splitting the ICE output into two parts. rotating stator control unit generator ~ ~ generator gasoline engine traction motor ICE planet gear Fig. 7. Combined hybrid with planetary grar The first part is proportional to the difference between the ICE and car speed and the second is proportional to the car speed. The first part is transformed into electric energy in the generator and supplied to the traction motor. The second part is transferred by the output planet shaft directly to car wheels. This scheme allows controlling the engine speed and torque and this is the way how to minimize fuel consumption. Electric power splitting drive using DC machines was used on Czechoslovak express motor cars in the year 1936. The patent document was emitted in Czechoslovakia with Nr 53 735 on 25. February 1936. [1], [2], [3]. DC machines were usual on railway vehicles at that time. The vehicle was called :†Slovenska Strela† and remained in service till the year 1950. It should be reconstructed and modernized later on. But electrification of the main railway connection between Prague-Kosice replaced this very interesting vehicle with express electric locomotives. Fig. 8. Express railway car â€Å"Slovenska Strela† clutch rotor output shaft Fig. 9. Electric power splitting drive of express car â€Å"Slovenska Strela† The ICE drives a DC generator which â€Å"stator† and rotor can rotate separately. The â€Å"stator† is firmly coupled with the ICE shaft. The rotor is coupled with car wheels. On the car shaft is mounted a DC electric traction motor supplied by the voltage induced in the generator. The splitting is performed in the generator. The relative speed between generator â€Å"stator† and rotor is difference between the ICE and car speeds. This solution allows split the ICE output into two parts. The first part is proportional to the difference between the ICE and car speed and the second is proportional to the car speed. The first part is transformed into electric energy in the generator and supplied to the traction motor. The second part is transferred directly by means of electromagnetic torque in the generator air gap to the car wheels. This scheme allows controlling the ICE speed independently from the car speed and this is the way how to minimize fuel consumption. Model of Electric Power Splitting Drive Using AC Machines was implemented in the laboratory of Josef Bozek Research Center of Engine and Automotive Technology at the Technical University in Prague. The physical model of the drive is seen in Fig. 10. It is experimental electric hybrid car drive of a small power. [5], [9], [11], [13], [14], [15]. The output is 7. 5 kW, 0 – 6000 min-1.. Electronic converters and supercapacitor EC are integrated in the circuit between electric power divider SPGM and traction motor TM. The super capacitor as a peak energy storage has 100F, 56V and 400 A. It is able to accept the kinetic energy during braking the vehicle of the mass 1500kg from the velocity 60km/hour and regenerate it during next speeding up. Principle of the system is depicted in Fig. 10. The combustion engine COM ENG drives the electric power divider SGPM. The power divider is a special double rotor synchronous permanent magnet generator. The first rotor is firmly connected with the combustion engine shaft. The second rotor is firmly connected with the traction motor TM and with car wheels. The traction motor is supplied with electric power induced by differential velocity between first and second rotors. Parameters of this electric power (voltage, current and frequency) are changed in electronic converter in EC. Power of the combustion engine is divided into two parts. used for evaluation and comparison of car’s performance, pollution production, efficiencies etc. Simulations were performed on New European Driving Cycle NEDC. The NEDC is shown in Fig. 11. Total distance 10,9km Speed (km/hour) EC ELM CLUTCH COM ENG TM SGPM base Fig. 10. Physical model of Electric Splitting Drive Using AC Machines The incoming power P1=T1* ? 1 is the power of combustion engine producing torque T1 at angular velocity ? 1. Torque T1 is transferred with electromagnetic force to the second rotor, rotating at angular velocity ? 2 which is the same as car velocity. Power transmitted to car wheels by this torque is therefore Pm=T1*? 2. Remaining power is induced by magnetic field into the electric winding arranged on the second rotor. Neglecting losses this power is Pel=P1-Pm=T1*(? 1-? 2). Power Pel is transferred via electronic converter in EC to the traction motor TM and finally added to power Pm on car wheels. Incoming power P1 from combustion engine is by this technique divided into two parts Pm and Pel. Combustion engine can rotate with angular velocity which does not depend from the car velocity III. SIMULATION OF FUEL CONSUMPTION OF HYBRID ELECTRIC CARS Main advantage of electric hybrid cars is the diminishing of fuel consumption. The production of CO2 depends on the fuel consumption and on the working conditions of the ICE. The working conditions of the ICE are much better in electric hybrid cars than in conventional cars generally. Simulations were done with the mathematical model of Electric Power Splitting Drive Using AC Machines. Measured parameters and features obtained in the laboratory [11], [13], [14] were used for the simulation. The mathematical model of a conventional car and hybrid electric car with electric power divider was established in [15] [16] Comparisons of this art are usualy done on different standard driving cycles. Standard driving cycle represents a driving pattern of a certain geographic region (North America, Europe, Asia-Pacific). These driving cycles are Time (s) Fig. 11 New European Driving Cycle Parameters of compared cars and results of simulation are shown in Tab. 1 TABLE I SIMULATION RESULTS Vehicle type, manufacturer Driving Cycle Total mass (kg) Specific Consumption during total NEDC (l/100km). Total emissions CO2 (g) Specific emissions (g/km) First case Second case NEDC Skoda 1. 2HTP NEDC 1450 1120 5. 1 5. 9 1333 1540 122. 9 142 Model Fabia Two cases are shown. In both of them the New European Driving Cycle was simulated. Case first: Hybrid electric car with electric power divider. The mass of the car respects the additional mass of electric part of the powertrain. Case second: Conventional car Skoda Fabia 1. 2 HTP. The results shown in Tab. 1 allow to make following conclusions: When comparing fuel consumption and CO2 emissions between hybrid car with electric power divider versus conventional car of the same class (that means the same primary ICE engine power and respecting additional mass of the electric powertrain machines), we can conclude that the fuel consumption and CO2 emissions are significantly lower at the hybrid car. Hybridization of such cars brings not only fuel savings but also is much more environmentally friendly. I. CONCLUSION The production of dangerous greenhouse gas emissions and consumption of world energy resources become a serious problem. Especially CO2 emissions can influence the climate stability of Planet Earth. The automobile business contributes to this development a lot. But the automobile technology has space to be improved. The electric and hybrid electric vehicles can contribute to diminishing of fuel consumption and green gases production. The hybrid electric vehicles makes it possible to operate the combustion engine in more suitable regimes with better fuel combustion conditions. Some hybrid systems even enable to operate the combustion engine in best relation between power and revolutions. Systems with power dividers allow the engine to operate in revolutions that are quite independent from the car velocity. Simulations were done with the mathematical model of Electric Power Splitting Drive Using AC Machines. Measured parameters and features obtained in the laboratory were used for the simulation. Simulations were performed on New European Driving Cycle NEDC. Results of one commercial car and one hybrid electric car with electric power divider are published. Fuel consumption of the hybrid car on the new European Driving Cycle was 5,1 l/km. The commercial car consumed 5,9 l/km. The hybrid car consumption is 13. 6% lower then at commercial car. Similar numbers were obtained with respect to CO2 production. The hybrid car produced 1333 g CO2 on the New European Driving Cycle. Commercial car produced 1540 g CO2. Hybrid car with electric power divider produced 13. 5% less CO2 . REFERENCES [1] V. Klima : Electro-mechanic drive DELKA and its comparison with Dieselelectric drive.

Global Warming Essays -- greenhouse gases climate change

Global Warming The greenhouse effect occurs when gases such as methane, carbon dioxide, nitrogen oxide and CFCs trap heat in the atmosphere by acting as a pane of glass in a car. The glass lets the sun light in to make heat but when the heat tries to get out the gases absorb the heat. Holding this heat in causes heat waves, droughts and climate changes which could alter our way of living. The main gases that cause the greenhouse effect are water vapor, carbon dioxide (CO2), and methane, which comes mainly from animal manure. Other gases like nitrogen oxide and man made gases called chlorofluorocarbons get caught in the atmosphere as well. The decay of animals and respiration are two main but natural sources of carbon dioxide. There are many steps we can take to slow down the emissions of greenhouse gases. There are already so many gasses in the atmosphere, and we may not be able to correct the damage done, but we can’t prevent further damage. Over the last 100 years the global temperatures have been increasing slowly but steadily. Since 1980 the temperature has risen 0.2 degrees C (0.4 degrees F) each decade. Scientists predict that if we continue putting the same amount of gas into the atmosphere by the year 2030 the temperature will be rising as much as 0.5 degrees C (0.9 degrees F) or more per decade. Over all the global temperature could rise anywhere from 5 to 9 degrees over the next fifty years. If the temperatures do rise as predicted several things co...

How Is Black Magic a Silent Killer

Abstract Introduction The word’ magic’ is very old, oldest of the oldest, it has been in existence from the time immemorial. WHAT IS MAGIC? Black Magic is an ancient science that uses the five elements or the visible/invisible chemistry, physics, biology, electronics & ether (universal spirit) to hurt or heal people. The core of all black magic lies within the spirit world or the world of the dead. Details Potency and Influence: The magic is based on natural and supernatural forces, which exist along with other four basic forces and these are numbered as fifth and sixth energy. The scientific basic forces are gravity, weak and strong, electromagnetism, the nuclear power, weak and strong. Fifth is natural command and sixth is supernatural force. Human being has a strong composition of both desires in him or her, good and bad, either to help or to harm others. This magic influence is in the genes of every person and this potency is called Positive Energy and Negative Energy. Some have more percentage of positive energy in them, which urges them not only to help self but also others in all spheres and in all possible ways as they can possibly exercise. The people with more positive energy even go out of the way to help others. There are other types of persons who gain pleasure in causing mental injury or otherwise to other persons, places or things due to jealousy or their basic nature. These are certain people who have high proportion of negative energy in their specific genes. They feel pleasure to harm others by using black magic either to gain something in exchange or to get enjoyment out of it. This practice has been common even long before Christianity. The people in ancient days used to blame devil for every offensive or annoying act, it was just because the genuine procedure had been a mystery during that period. *2. 2. Black Magic*: A mystic art: Black Magic is a mystic art of rituals or using one’s evil supernatural powers to influence or control events, sorcery or witchcraft. It is a sort of hypnotism, though its methods are different. It is exercised to affect malevolent powers deliberately to cause damage to other persons, places or things, directly or indirectly by its misuse. This term is also used with ‘K’ such as magick, and the people popularly use this term as ‘Black Magick’ or ‘Dark Magick’ and when it is used for giving benefit to a person it is called White Magic or White Magick. White Magic and Black Magic (or Dark Magic) are the requisites used in place of Positive Energy and Negative energy, which can both benefit a common man, place or thing temporarily or can cause damage to any of them. Stronger the will power of a man, lesser the effect of Black Magic, stronger the stars of a person astrologically, negligible force of black magic effect. Similarly if the place or thing is more pious or holy, little the evil effect of the black magic. Does the Black Magic really work? The magic or black magic does exist, no question of modern people rejecting it. It is the energy that exists in every person, depending on one’s thinking and nature of soul, pious or evil. This energy can be increased to a great extent either in giving benefits to a particular person or harming any other person, place or thing. A term taboo is also used for this. It was a custom among the Polynesians, who prohibited the use of certain persons, places or things. It normally forbids the use of physical connections with a particular person or woman. They generally accepted opposite term for the black magic or dark magic and that is white magic. Sorcery is a branch of basic magic that can influence certain desired events, objects, people and the places by its mystical supernatural powers to a great extent. Such Magical power affects have dual functions, they can heal as well as harm, and they can benefit as well as damage any person, place or thing. But more affectivity is related to negative power. How does this kill? Voodoo Witchcraft comes from the African continent & is extremely lethal. In the last few years it has spread into other parts of the world & is being mixed with other forms of Black magic to harm and kill people. The clothes, hair, nails and picture are used to make a doll that resembles the victim; the heart area of the doll is kept open for the final ritual. A ritual is performed and a heart is pulled out from a live animal’s body while it is vibrating and placed into the heart area of the doll, at this point the doll is infused with life connecting the doll with the victim with an invisible psychic chord. Once the doll and the victim are connected, 2-3 inch needles are pushed in the doll at specific acupuncture points to break the energy system of the victim. As the pins are pushed into the doll the victim feels as if a needle is being pierced into his body. The victim can be sitting thousands of miles away and will experience the attacks instantaneously. If the victim was made to eat or drink food and/or water that consists of â€Å"Masaan† (Ash of the Dead) infused with negatively charged energy by the black magician, the effects are life threatening and gives unlimited control over the victims Mind & Body. The prime focus of the black magician is to destroy the immune system of their victim. In case of a man: head & temple area, thumbs & big toes are targeted to break the immune system. In case of women, private parts are attacked to terrorize & harm the victim. The individual can be killed using this technique in as little as 28 days (one Moon cycle). If the individual is physically, mentally, emotionally & spiritually strong it becomes very difficult for the attacker to kill the victim within a specific time period and the attacks can continue for years until the victim or the black magician dies. As the attacks continue the victim is torn down on multiple levels; gets bed ridden and eventually dies of no apparent medical reason. The doctor's cannot help him because the symptoms misguide the doctors into giving the individual stronger treatments with every passing day and one day the body gives-up.

Lord of the Flies †An Alternative Ending Essay

Ralph looked up. He knew he was imagining things, and that had to stop. He focused on the essential things in life. Pigs. Sharpening sticks. Killing. Ralph stood and, set with a determination to fuel his desires, he exited the cave. He had been living in the cave for the past month. There was nothing left on his body save for a loincloth and markings on his body. He had been different from the other people since discovering the power. The power to kill the remaining survivors. Ralph walked down to the beach. The palm trees and sandy beaches were once a haven to the boys. Once. Now they were just obstacles in a war for both sides. Since Simon had died, and Piggy had disappeared, the â€Å"hunters† were fighting a war against Ralph. But luckily, none of the boys had been brave enough to kill Ralph ever since that fateful night. Ralph closed his eyes and let his memories take over. ***** It was dark that night. The boys had given up trying to chase down Ralph. Ralph had retreated to a cave, but he was too impatient to wait till the morning. He wanted to try to persuade the Hunters to change their allegiances to him. He was walking towards the sandy beach towards the rocky outcrop, taking his time, anything to delay persuading the hunters. His new found conscience was urging him along. â€Å"Go, Ralph! You might never get another chance like this!† â€Å"No!† Ralph cried! The conscience retorted, â€Å"What happened if you were bullied by a boy? Would you go confront the boy, or run away like a coward?† â€Å"This is different! These are boys, humans, like me!† yelped Ralph. â€Å"Just do it. Get it over with.† The conscience insisted. Ralph considered, â€Å"5 minutes only.† When he reached the rocky outcrop, Ralph decided to climb up the steep and potentially hurtful rock in secret for fear that the hunters would see him and not allow Ralph up to discuss matters. As he climbed to the top, the rock he was reaching for suddenly came loose and gravity took hold. Ralph prayed that the rock that hit the bottom wouldn’t make a sound. Luckily, it hit the waves and was dragged out by the tide. As Ralph struggled over the top, he saw 5 spears pointed at him, like deadly stakes. â€Å"Why are you here?† spat a savage. â€Å"I need to talk †¦ to all of you†¦Ã¢â‚¬  gasped Ralph, tired from climbing up the rock. â€Å"Get lost†¦ We don’t need to talk to you. You and us have nothing to do with each other!† snarled a savage. Roger, Ralph guessed from the intensity of the words. â€Å"It concerns about being rescued.† Ralph said with the ferocity of being a leader. â€Å"How ’bout we just kill you?† â€Å"Because I want to speak with Jack!† Ralph said the last three words ferociously, hurling himself over the edge. â€Å"What do you want?† spoke a quiet, bored voice from the darkness. â€Å"I have come to offer a treaty† â€Å"Get out.† Ralph’s anger, hatred and bitter emotions flowed out of his body in a rush of fury. â€Å"No.† he spoke with hatred about Piggy. â€Å"Get out before I kill you!!† roared Jack. thump. thump. thump. â€Å"Ignore th-!† screamed the conscience. The savages jeered â€Å"We’ll just roast you on a spit, just like a pig!† thump. Thump. THUMP. â€Å"KILL THEM!!!† shrieked the conscience with a sheer overwhelming force of hatred and cunning. Suddenly, Roger lunged for Ralph. Without warning, Ralph’s hands came up †¦ and found them on Roger’s throat. Ralph could feel this reborn conscience taking over his body†¦ and his mind. He was powerless to do anything or stop his hands. He felt the conscience growing bigger, and making him weaker. Soon, he was the conscience, and vice versa. â€Å"STOP!!!† Ralph screeched, â€Å"You’re meant to be my conscience, not take it over!† The conscience laughed â€Å"Too late, Ralph. You missed your chance. What goes around, comes around.† With a growing sense of horror, Ralph was watching, through his own eyes, the terror that unfolded. He felt the conscience becoming more and more confident, and he closed his hand on the neck. Of course, Roger struggled, however, he was no match for somebody who was strangling him with two hands. After a few seconds, Roger stopped moving. Subsequently, everybody in the vicinity could hear a sharp snap. Suddenly, panic broke out. Everybody but Ralph and Roger started screaming, and all of them were in a frenzy trying to escape – from the monster that had become Ralph. The horror of killing something worse than just a pig, about killing Roger simply for absolutely no reason, or that Ralph was always the one to uphold justice but was practicing otherwise. Feeling the blood gushing down his hands, the screams of the littleuns and biguns, the feeling of a cold hard body in his hands. His heart beat faster and faster, and he screamed. His head spun and he dry heaved. He was becoming more and more nauseated as he plummeted into the abyss. Claws grabbed him from below and tried to rip his skin. Blood materialized in his vision, but it wasn’t Ralph’s – it was Roger’s blood. He felt a searing pain on his arms and his head hurt so much†¦ ***** Ralph painfully opened his eyes. He wasn’t used to the amount of sunlight on his face – not anymore. He climbed up the rock leading to the savages’ hideout, intent on inflicting pain onto them, not caring about being rescued, about the honor of the fire, or the conch. For he, had become the Beast.

Essay Termination Act

Essay Termination Act Essay Termination Act Jacqueline Torres February 4th, 2013 Mr. Valdez / 2nd period Termination Act Like many other policies, the Termination Act originated in ideas that were meant to benefit Native Americans, but was this act a benefit to the Native Americans or was it disastrous for them? This act was meant to reduce federal expenditures, a goal popular among taxpayers. I believe that this policy was non beneficial for the Native Americans even though the impact of termination was small. This act affected just over 13,000 out of a total Indian population of 400,000. Only about 3 percent of reservation land was lost but it caused huge anxiety amongst Native Americans and had the ironic result of challenging the formation of the ‘Red Power’ protest movement of the 1960s. It remains an emotive issue among historians sympathetic to Native Americans. Termination proved to be a really bad failure everywhere. Congress passed the Klamath termination act in 1954, which was â€Å"a measure authorizing the sale of reservation lands and establishing procedures for terminating all federal relationships with the Klamath Tribes. Enrolled tribal members then chose whether they wanted cash payments for their share of the land or if they wished to retain their shares in the former reservation and participate in a management plan.† Many Klamath people were prepared to manage their payments, and Klamath County experienced some of the highest unemployment rates in the state. Alcoholism increased, welfare

Such ethical issues have a great impact on the consumers directly and to the society. Consumers always imagine they pay so much money because these companies spend a lot in advertising their products (Al-Nuemat Ahmed: pp. 58). However, since marketers are good at deceiving consumers, they always use the concept of deceptive marketing to lure them into buying. They do this by lowering the product prices but still putting into consideration the expenses. This kind of ethical dilemma has also made consumers materialistic because they tend to change their primary needs. In the process, the society ends up facing many problems. This is because people are quick at judging what other possesses and not how they behave in a society. Companies rely on marketing techniques to increase the number of sales. However, in the process of doing so, they always end up feeding consumers with wrong information through misleading advertisements. This is because they are after gaining a competitive advantage over their rivals. This in turn hurt the consumers after they realize the health issues related with the products.

Police Operations - Research Paper Example Introduction ‘Acculturation’, as a term, is commonly utilized in the discussions which surround refugees and immigrants, focusing on the cultural changes needed to be made in the behavioral traits of the immigrant groups to get imbibed in their host nation’s culture. To be noted, the present acculturation technique is used in the various organizational departments such as fire and police departments. In the year 2004, the International Organization for Migration (IOM) defined acculturation as â€Å"the progressive adoption of elements of a foreign culture (ideas, words, values, norms, behavior, institutions) by persons, groups or classes of a given culture† (Sam & Berry, n.d, p.11). In recent times, acculturation has often been regarded as an important and well organized area of study. Acculturation is a kind of dual process of psychological and cultural changes that take place as an outcome of contact among two or more diverse cultural groups and their res pective individual members. The conventional definition of acculturation was offered by Redfield, Linton and Herskovits as â€Å"acculturation comprehends those phenomena which result when groups of individuals having different cultures come into continuous first-hand contact with subsequent changes in the original culture patterns of either or both groups† (Berry, 1997, p.5). ... With the process of acculturation, police officers will be benefitted by the adaptation of the behavioral patterns of the surroundings (Berry, 1997; Berry, 2005). The new police officers also develop the manner of acculturation which allows them to work in the new environments. Police officers mainly deal with the dimension of criminology, which needs intense pressure handling ability along with logical thinking which can be quite difficult for the new entrants or new officers. Correspondingly, this process of acculturation has been introduced so that new police officers can get habituated to work in the new environment. This research study deals with the way of applying acculturate to the new police officers. In this study comments on present research, subculture of policing along with the consistent cultures that most law enforcement agencies possess, based on critical explanations (Berry, 1997). In the earlier period, acculturation was viewed as a process of change, leading to cer tain specific outcomes. Originally, acculturation was conceptualized mostly as a linear and uni-dimensional procedure with the practice occurring on a continuum. Modified perspectives have enlarged the view of what the potential outcomes might entail. Instead of a single linear continuum, a multidimensional or multi-linear model focuses on an individual position on the both new as well as original cultures norms (Trinh, 2009). Acculturation Process A General Framework of Understanding Acculturation (Berry, 2005) New officers can never be acculturated with the lack of an appropriate process. According to the above framework, there are cultural acculturations in the group level and psychological acculturations in the individual level, which need to be satisfied by the police
