Legal Problems - Essay Example The major issue which arises is therefore, negligence on the part of Kowloon Bank and whether they had a duty of care towards Lester and their employees. The salient principles of tort law establishing injury and harm to plaintiffs have been derived on the basis of judgments which have been set out in various cases such as Donaghue v Stevenson1, Anns v Merton Borough London Council2, Murphy v Brentwood DC3 and Caparo v Dickman4, which form the basis for the duty of care that forms the foundation of tort law. All of the above cases have established the â€Å"good neighbour† principle, wherein a person owes another a duty of care and this would especially be the case with employees having a duty of care towards their employees. The prevailing standard for medical negligence has been established in the case of Bolam5, i.e, the question of whether negligence has occurred must be assessed based upon whether a body of medical staff finds negligence to have occurred. McNorrie argues that the standards established in Bolam were bad in principle.6 He cites the case of Cavanagh v Ulster Weaving Co Ltd7 where employers were held to be liable for not taking good care of their employees. It must be noted at the outset that Lester had a disability and would have been responsible for equipping himself with necessary aids, such as a crutch in moving around the premises of the bank. Alternatively, he could have also requested such aids from the bank to enhance his mobility. The bank itself did all it could, i.e, providing him an ergonomic chair, etc. On the issue of not putting up signs that the floor was wet, the person liable would be the individual employee/cleaner who failed to post signs to state that the floor was wet, rather than the bank itself. Secondly, the magnitude of Lester’s injuries might not wholly have been caused by the wet floor, because he was already disabled with a limp. Secondly, the delays which occurred were mainly because of the

The Tellâ€Tale Heart Essay Example for Free

The Tell–Tale Heart Essay Although the narrator in â€Å"The Tell–Tale Heart† insists that he is not insane, I believe that he is insane. The madman hears unrealistic sounds. Moreover, he murders an old man with nonsensical reason. The narrator kills the old man because the old man’s eye frightens him. As the narrator says, â€Å"One of his eyes resembled that of a vulture a pale blue eye with a film over it. Whenever it fell upon me my blood ran cold, and so by degrees, very gradually, I made up my mind to take the life of the old man, and thus rid myself of the eye forever. † This conveys that the narrator decides to kill the old man because he does not like the old man’s eye. Sane people do not kill others without an appropriate reason. The narrator, on the other hand, kills the old man with an inappropriate reason, thus proving his madness. The narrator hears sounds that sane people do not hear. In paragraph 1 sentence 3, the narrator says, â€Å"I heard all things in the heaven and in the earth. I heard many things in hell.† Later, after he kills the old man, while he sits with the police who had come to the old man’s house because of a suspicious noise, the narrator says, â€Å"My head ached, and I fancied a ringing in my ears; but still they sat, and still chatted.† He hears delusionary sound of the dead old man’s beating heart. These tell me that he is insane because he hears what sane people do not hear. He says he hears a sound of the thing that is not real. In conclusion, I believe the narrator is definitely mentally ill. He murders the old man with thoughtless reason. He hears auditory hallucinations which the sane do not hear. Although the narrator does not believe he is insane, his actions and expressions in the Tell-Tale Heart are proves that he is completely insane.

The Moon is Down :: essays research papers

Throughout known history the system of democracy seems to be the most just, the most logical and the fairest of all ruling systems. Its ability to adjust to changing times is only one reason for its perseverance. In John Steinbeck’s The Moon is Down, this durability is displayed through the townspeople led by Mayor Orden, under the oppressive heels of their conquerors.   Ã‚  Ã‚  Ã‚  Ã‚  One of the most obvious examples of democracy’s endurance is the resistance displayed by the townspeople against their invaders. The oppression and invasion of the conquerors arouse, instead of crush, the desire in the defeated for freedom. These people, who have lived with the idea of a free rule of democracy, refuse to be chained down under the oppressive rule of the conquerors. It is for this reason that they strike back at their invaders. As said by Mayor Orden to Colonel Lanser of the aggressors, â€Å" ‘The people don’t like to be conquered, sir, and so they will not be. Free men cannot start a war, but once it is started, they can fight on in defeat. Herd men, followers of a leader, cannot do that, and so it is always the herd men who win battles and the free men who win wars.’ † [pp. 185-186] Thus, it is because of their freedom that people believing in the free rule of democracy do not let down and die when conquered, do not accept their being robbed of their rights, and fight against what is unjustly done to them.   Ã‚  Ã‚  Ã‚  Ã‚  The townspeople fight on again, perhaps with even more resolve, after the execution of Alex Morden, instead of their spirits being crushed, as was the intent. The entire purpose of Alex Morden’s public execution was to dissuade potential upstarts, but the result was the exact opposite of what was desired. The public display only empowered the townspeople’s resolve to fight back. To put it in Mayor Orden’s words, â€Å" ‘Our people are invaded, but I don’t think they’re conquered.’ † [p 139] Consequently, these people refuse to be put down, and, when faced with situations like Alex’s death, are not deterred but continue on with strengthened resolve.   Ã‚  Ã‚  Ã‚  Ã‚  While resistance is one aspect of democracy’s endurance, determination is another powerful ability it has, as it is shown in the Anders boys’ escape to Britain for help. Because of their overwhelming desire for freedom, the townspeople were willing to, and did, try anything possible to rebel against their invaders.

Child Study Paper Essay

The Child Study data I have gathered comes from the observation I have completed at Mission Bell Elementary School. Mission Bell Elementary School is a local school in Riverside. In the P. M preschool class there are 24 students, one teacher, and one assistant. The child I decided to observe is names Zoe. Zoe is 4 years and 10 months old. I immediately was drawn to Zoe because she had such a big personality, was very social, and smart. I am glad that I choose to observe Zoe because she was able to make my observation process smooth and easy. While observing her I had to pay close attention to her biosocial development, motor skills, cognitive skills, communication skills, emotional development, social interaction, and her self-esteem. As I share my observation data, I will give examples of Zoe’s skills and overall development thus far in her life. Biosocial Development: Physical Description According to biosocial development norms Zoe is average. She is just the size she is suppose to be according the growth chart and development norms. Zoe is tall and lean. She is on the skinny side and has long arms and legs and a flat stomach. Zoe weighs 36 pounds and is 39. 75 inches tall. On the growth chart Zoe is in the 50th percentile (CDC 2000) when it comes to her weight and is in the 25th percentile (CDC 200) when it comes to her height. From these percentages on the growth chart Zoe is falling right in the middle when it comes to her physical development, showing that she is growing at a normal expected rate. Zoe displays an above average activity level in comparison to her peers. She has such a high activity level compared to the other children because out of them all she is the one that keeps busy. When indoor play time comes around Zoe is sure to play at as many play stations as she can. Zoe averages about 5 to 6 play stations. Zoe chooses to play at a number of different areas, whereas, many of the other children just get around to two different play stations. At each station Zoe spends 41/2 to 5 minutes playing, showing that Zoe’s ratio of active running around periods out weight the inactive sitting and playing periods. Motor Skills Zoe does a does a good job at controlling her gross-motor skills as well as her fine motor skills. Zoe has good balance and speed for a 4 year old. When Zoe’s gross-motor skills are compared to her classmates you notice her advancement. She does not stumble over her feet or object such as the carpet, as much as her peers do. When Zoe is outside her favorite activity is to play on the jungle gym. This activity is able to show Zoe’s good development of gross-motor skills because of how she is able to climb up and down the stairs of the jungle gym and with such speed. â€Å"Many children by age 2 become smooth and rhythmic – secure enough that soon they leave the ground. (Berk, 2007, P. 224). Zoe has mastered her fine motor skills. Zoe is able to correctly hold writing objects such as markers and crayons; she also holds glue sticks in the writing position. She holds the maker or writing object in between her thumb and her middle finger and allows her index to help support her writing tool. By having this technique down Zoe is able to control the lines that she makes on her paper as well as how dark her lines will be. She is also able to manipulate how much glue is going to go onto her paper and where it will go. In comparison to Hayliegh (3-8), who is still holding her writing tool with her palm, Zoe shows she is more advance in her fine motor skill. While playing at one of her favorite indoor play stations, which is play dough, Zoe uses her hands to manipulate the play dough into various shapes and objects. The way she is able to grasp and squeeze the play dough shows her sensatory skills, which are in connection to her fine motor skills. These two examples show that Zoe has master over her hands and how they will work to her advantage. As Zoe continues to play her favorite activity, the jungle gym, with such balance and speed she shows that she is comfortable with her movements. This is one of her favorite activities because it allows her to run around and get out her energy. Zoe favorite game, and only game she plays, are the computer games. Zoe will avoid such games as board games but will go and play on the computer when she can. The games on the computer help her to learn how to control an object such as the mouse and pointer. This helps Zoe in the development of her fine motor skills. Zoe’s favorite table game is play dough. The play dough station is always the first station that Zoe goes to if she is picked to go their. At this station Zoe again uses her fine motor skills to create all different types of objects with her play dough. Cognitive Skills While closely observing Zoe’s cognitive skills she showed evidence of Piaget’s preoperational stage. Zoe’s cognitive development is shown through her make-believe play. â€Å"Piaget believed that through pretending, young children practice and strengthen newly acquired representational schemes. † (Berk, 2007, P 227). When Zoe plays with her play dough she pretend that she is making pizza. She begins by taking a handful of play dough and placing it on the table, she then get a small rolling pin to roll the play dough out flat. Once the play dough is rolled out completely flat she uses little Lego’s to represent the pepperoni that tops most pizzas. Next she takes the finished pizza and puts it on the side of the table and pretends to heat it in an oven. The takes the play dough and begins to feed her friends. When Zoe decides to not just feed herself but her friends as well she is showing development of no longer being self-centered. This whole make believe shows how far Zoe’s Cognitive skills have developed. She is able to take something she see and act it out and think about the order in which she acts out each piece. Zoe has knowledge of classification and seriation along with her representation skills. Zoe shows that she is capable of classifying objects as well as putting them in sequence. She shows evidence of classification during clean up time. When it is time to clean up each toy has its own space and toys that are a like go into spaces next to each other. Zoe is able to identify objects and according to the likely ness of one to the other she can tell weather or not the go in the same area. For example Zoe is able to identify that the blocks and the Lego’s go into the same area but that they are different. She is also able to recognize that the entire book are books but able to classify them according to their size. She put away all the big books on one side of the bookshelf where they belong and all of the smaller books on the oppsite side where they belong. Zoe also knows sequence of numbers. She shows this when she is called up to be the calendar girl for he day. Zoe takes down all the numbers from one to 15 off of the calendar. Then one by one puts them back up in sequence. She also recognizes the patter of the numbers. Each number is written on an insect. As she puts up the numbers she realizes that the patters of insects are caterpillar, lady bug, butterfly, caterpillar, lady bug, butterfly and so on. Zoe shows the ability to imitate real life through her play. When she creates pizza with play dough and Lego’s she is showing that she understands how to create something from what she has seen and experienced. She shows that she understands how something that is not the original object can symbolize or represent the original. Zoe also shows role play during her play. She does show by pretending to be the baby while her friend Savanna (3-11) plays the mother. This type of role play shows that Zoe understands the various roles that people play in life. Through this role play you are able to see her ideas on life. Zoe shows her perception of how a baby is to act and how they should respond to their mother. By Zoe crawls around on the floor and talks baby talk shows how she views babies. Lastly Zoe shows special interest in activities that involve imitation play. She likes to create things that she sees and experiences in her life. This ability to imitate reality shows her cognitive growth. Communication Zoe uses wide variations of communication. Zoe uses her body language, facial expressions, and verbal communication all at once when she is explaining or expressing herself. All these combined show off Zoe’s personality. When Zoe hurt her foot on the table Zoe used her body language to show that she was in pain. She immediately bends down to rub her foot in try to make it feel better. Then her wincing face showed that it was not helping. As Zoe dragged her body over to the teacher she then verbalized the pain that she was in. She expressed the teacher, â€Å"I hurt my foot†. Zoe is very good at exaggerating her expressions and really showing how she feels on her face. If she is happy she has a big simile, if she is shad she is frowning, and if she is hurt she is wincing and showing pain on her face. Her facial expressions do a lot of the verbal communication she might not do or it tells her feelings before her words do. When Zoe interacts with her friends she is very animated and humorous. She is very big in her movements and throws up her arms and puts out her hands as gestures when she is speaking. When she is very excited about what it is she is telling her peers she is very big in her gestures and when she is calm she uses one hand when gesturing. Zoe has a very good vocabulary and is the talkative one of the group. She is also known for her slang vocabulary. Sometimes this slang that she uses from time to time goes a little too far and she can get into trouble. Hector (3-5) did jus that told on Zoe and got her into trouble. Hector told the teacher that Zoe told him, â€Å"What the heck. † Zoe was then told that she should not use that word. Zoe is also very descriptive in her speech. She once told the teacher, â€Å"Mrs. Contreras, I made a red strawberry†. Zoe is extremely talkative and this helps aid her in learning and broadening her vocabulary, as well as learning how to express her self. Emotions Zoe is at the Initiative versus Guilt stage according to Erikson’s personality development theory (Berk, 2007). Evidence of this is show when Zoe is eager to join her class peers in various activities. In particular when it is library time Zoe likes to thumb through her book initially by herself like she is told to do but it excited when she is able to share her book with a few surrounding friends, or listen to a surrounding friend share their book with others. When it comes to creating a new picture or trying a new activity Zoe becomes excited to participate and learn something new. This took place when she had the opportunity to create a caterpillar. She learned how many circles she needed to make the caterpillar and where to glue on the legs of the caterpillar. Zoe also shows evidence of autonomy because she is able to use her mental development and sense to determine and recognize that she has to use the restroom. When it comes to Zoe’s Temperament she is not moody. She consistently is happy and friendly unless she gets hurt or someone copies her. She is usually very approachable and social with everyone. Her response positively when it comes to playing with someone new at each play station that she goes to. She also is good at sharing. For example, when Zoe goes to play on the computer she shares the mouse with the other student and takes turns clicking on the computer. She works together with her peer to find the right answer to the question on the computer. Since Zoe is good at sharing this makes her approachable and fun to play with. When it comes to Zoe’s intensity of her reactions she is directly in the middle. She is not a loud child but also not quiet. She also is good at having self control and not having tantrums. She does have very out there over the top facial expressions and gestures but not so much to make her an intense child. Zoe is also positive in her mood. If she is hurt or irritated she will tend to come down from her usually happy smiley mood. Zoe is usually happy and playful. Zoe is just about always in a very positive mood and a pleasure to be around. However, Zoe does show a broad range of emotions during her observation. She showed happiness while she was interacting with her peers, and she also displayed the feeling of being hurt, when she stubbed her toe on the table. Zoe displays knowledge of how to express herself emotionally. Social Interaction Zoe is very social and interacts with everyone. Zoe is always interacting with new peers when she is indoors going from one play station to the other. Zoe is a little different from the other girls in that she has no problem interacting with the boys. Around lunch time Zoe joins in when Dillon (4-7) is pretending to be a superhero. Zoe joins in and pretends to be a super cat. When Zoe does interact with her peers it is in a small group of maybe 3 at the most. Zoe never tends to be around large groups. Mostly you will see Zoe one on one with another peer. Zoe tends to go towards the sensatory play then the make believe play. When Zoe has a choice of an indoor play station she always goes for the play dough first. After that Zoe will do arts and crafts that involve gluing or draw a picture. By the end Zoe always ends up at the Sand table. These three types of play that Zoe consistently participates in are all dealing with her sensatory skills or fine motor skills. These are Zoe’s favorite types of play because she enjoys playing with things that involve her hands, since she is good at them. Zoe has a secure attachment to her mother, teachers, and peers. When Zoe’s mother came to visit the class she did not attach herself to her mother while she was present. Zoe recognized she was there and called on her if she needed help but she did not play at the table that her mom was at just because she wanted to be next to her. Zoe continued to do her own thing. Zoe is also not attached to any particular peer in the classroom. She demonstrates this by sitting at a new lunch table with someone new with each observation. She also plays with someone new at each play station. Some of the other children especially girls are attached to one another each observation. They will always sit together at lunch and play together in both indoor and outdoor play time, but not Zoe. Self Esteem Zoe displays confidence and high self-esteem. She indicates that she has a very positive outlook of herself through her expressions. When Zoe does something correct she wants everyone to know. For example when Zoe did a good job of cleaning up her mess and helping her peers pick up wooden blocks she went to the teacher Mrs. Contreras to show her what she had done. Zoe will not shy away form getting others to acknowledge her feelings weather positive or negative. This shows that Zoe is confident and knows when she is doing good and not doing well. Zoe is confident enough to speek up when she wants to. Zoe is her own motivation. She is a self starter and needs little direction. When it is reading time Zoe will get her book and begin reading. While most of her other peers need a reminder to sit quietly and look at their book, Zoe doesn’t. Zoe will also do things when she is asked and will not need a motivation to do it, like and incentive or a reason. Zoe might need some help with staying focused for more than five minutes on one task, but when it comes to starting a task Zoe will not waste time getting to it and starting it. Zoe usually needs little direction and makes up her mind fairly quick when it comes to deciding where she wants to play and what she wants to do. She needs little self direction and Zoe tends to play at areas where she will receive as less direction as possible. Zoe is independent and is able to handle her own. She has no problem with playing alone and being by herself. She enjoys the company from her peers but she is able to entertain herself. She doesn’t need to have other peers around her in order for her to have fun. She also is more of a leader and to be a leader you have to have an independent sprit. Zoe has other peers who follow her around and does what she wants to do. Since Zoe is not a follower she is showing she is not dependent on other but is independent. Conclusion Zoe displays a number of strengths as well as areas that she can improve. Zoe is strong in her fine motor skills. The way she is able to control her writing tool and where her lines will go on her paper and how dark they will be. She is also able to stay inside of the lines. These examples show that Zoe has done a good job of developing her fine motor skills. Zoe is also very good with her communication skills. She knows how to express herself correctly and clearly. She is able to not only use her body language and facial features to let show one know what she is feeling but she is able to verbalize it. Zoe can afford to improve on her attention span. Zoe tends to be easily distracted by the idea of moving on to something else. She needs to learn how to focus on one thing instead of trying them all. She needs to learn how to relax and be persistent in what she is working on. Overall I have enjoyed the opportunity of observing Zoe. She has taught me various things about the development of a preschooler. I plan on remembering this observation and using it as I go on to my future career working with children.

Perspectives: US and Iraq Essay

Globalization has paved the way for technology to thrive. Economic growth is rooted in a country’s ability to expand on technologies that would productively utilize its resources. As a catalyst for capitalism, technology has often been used as a benchmark for nations to determine their status of development. Among the developed countries, the United States of America (USA) is one of the leading industrial powers of the modern world. Its contributions to the scientific community have improved the lives of millions of people due to their open economy and democratic identity. However, for most Arab countries like Iraq, technological advancement is a struggle since the interplay of religion and culture in its political history has slowed down its economic progress. This paper aims to offer an insight into the glaring differences of technological advancement from the perspective of a developed and developing country. The USA is flowing with scientific innovations that cater to the different needs and wants of each individual. This is due to the fact that its educational system fosters creativity and encourages competition as scientific projects and programs are supported by both the public and the private sectors. Since it is a country that flourishes in an open economy, the government is able to allocate the country’s resources to fund projects/programs that it deems necessary to maintain the status quo. With regard to Iraq, its violent history under a tyrannical ruler has hampered its progress in the realm of technology. While it is one of the oil producing countries, advances made towards scientific innovations were slim to none. Its previous government under the late Saddam Hussein had control over most of the telecommunication systems as well as transportation and electricity so citizens were deprived of such amenities. The education system is also inadequate as the country struggles to deal with the on-going war on terror after the fall of Hussein’s regime. At present, the Iraqi government is renovating its local and foreign policies to incorporate the expansion of Science and Technology into their development plan. The government is currently in an agreement with the UN Conference on Trade and Development (UNCTAD) on a development strategy that would support scientific innovations for institutions and businesses. In addition, an education plan was also created in the hopes of expanding the scope of science-driven educational institutions within the community as well as strengthening the workforce. The plan also supports student exchange programs with Universities from top schools in developed countries. The government has also opened its doors to foreign support in advancing knowledge in the field of Information Technology, Medical and Electricity. Conclusion: In all aspects of life, the use of technology is inevitable. Regardless of whether a country is considered developed or developing, technology will always be the driving force that propels a country to succeed in their aspirations for economic progress.

King Cobra Snake Facts

King Cobra Snake Facts The king cobra (Ophiophagus hannah) is a snake known for its deadly venom and impressive size. Its not truly a cobra (genus Naja), although both species belong to the famiy Elapidae, which includes venomous cobras, sea snakes, kraits, mambas, and adders. Its genus name, Ophiophagus, means snake eater. It is the king because it eats other snakes. Fast Facts: King Cobra Scientific Name: Ophiophagus hannahCommon Names: King cobra, hamadryadBasic Animal Group: ReptileSize: 10-13 feetWeight: 13 poundsLifespan: 20 yearsDiet: CarnivoreHabitat: India and Southeast AsiaPopulation: DecreasingConservation Status: Vulnerable Description The king cobra is the worlds longest venomous snake. Adults typically measure 10.4 to 13.1 feet in length, but one individual measured 19.2 feet. King cobras are dimorphic in size with males larger than females (the reverse of most snake species). The average adult of either sex weighs about 13 pounds, with the heaviest recorded individual weighing 28 pounds. The snake is brown or deep olive green with black and either yellow or white crossbands. Its belly is cream-colored or yellow. King cobras can be distinguished from true cobras by its two large scales on the top back of the head and chevron neck stripes instead of eyes. A king cobra may be identified by the two scales on the back of its head and the chevron pattern on the back of its neck. gaiamoments, Getty Images Habitat and Distribution King cobras live in India, Southeast Asia, and southern East Asia. The snake prefers forests near lakes or streams. Diet and Behavior A king cobra hunts using its eyes and tongue. Because it relies on keen eyesight, it is most active during the daytime. The snakes forked tongue senses vibration and transfers chemical information to the Jacobsons organ in the snakes mouth so it can smell/taste its surroundings. King cobras primarily eat other snakes, but will take lizards, rodents, and birds if necessary. When the snake is threatened, it tries to escape. If cornered, it rears its head and the top third of its body, extends its hood, and hisses. A king cobras hiss is lower in frequency than that of most snakes and sounds like a growl. Cobras in threat posture can still move forward and may deliver multiple bites in a single strike. Reproduction and Offspring King cobras breed between January and April. Males wrestle each other to compete for females. After mating, the female lays between 21 and 40 leathery white eggs. She pushes leaves into a pile over the nest so that decomposition provides heat to incubate the eggs. The male remains close to the nest to help guard it, while the female stays with the eggs. While normally not aggressive, cobras readily defend their nests. The eggs hatch in autumn. Juveniles are black with yellow bands, resembling a banded sea krait. Adults leave the nest after the eggs hatch, but may mate for life. The average life span of a king cobra is 20 years. A baby king cobra hatches from its egg. R. Andrew Odum, Getty Images Conservation Status The IUCN classifies the king cobra conservation status as vulnerable. While its difficult to gauge the number of remaining snakes, the population is decreasing in size. King cobras are threatened by habitat loss from deforestation and are heavily harvested for skin, meat, traditional medicine, and the exotic pet trade. As venomous snakes, cobras are often killed out of fear. King Cobras and Humans King cobras are well known for use by snake charmers. Cobra bites are extremely rare, but most cases of bites involve snake charmers. King cobra venom is neurotoxic, plus it contains digestive enzymes. The venom can kill a human within 30 minutes or even an adult elephant within a matter of hours. In humans, symptoms include severe pain and blurred vision which progresses to drowsiness, paralysis, and ultimately coma, cardiovascular collapse, and death from respiratory failure. Two types of antivenom are produced, but they are not widely available. Thai snake charmers drink a mixture of alcohol and turmeric. A 2012 clinical study verified turmeric confers significant resistance to cobra venom. The mortality rate for untreated cobra bites ranges from 50 to 60%, implying the snake only delivers venom about half the time it bites. Sources Capula, Massimo; Behler.

Free Essays on The First Crusade And The Idea Of Crusading

The First Crusade, a Holy Expedition Peace and tranquility in the eastern Mediterranean seemed secure for years to come in or around the eleventh century, but little did anyone know what loomed on the horizon. Jonathan Riley-Smith, a professor and specialist in ecclesiastical history at the University of Cambridge depicts in detail the holy war fought on Christ’s behalf in an attempt to liberate the people and the baptized members of the churches under Muslim rule, as well as the liberation of a place, that place being Jerusalem. The word crusade, which is derived from the Latin word crux, or cross, is in reference to the crusaders who were motivated by God, and in turn accepted the vow proposed by Urban II by bearing the cross on their skin or sewn onto their clothing in show of faith to the man they all believed in, Christ. At a gathering in Clermont, France in November of 1095, Pope Urban II preached the Crusade, known throughout France as the via Dei or way of God, to a mostly clerical assembly. It is made apparent to the reader that this concept of divine war for Christ introduced by Urban II, was not the first time a proposition like this had arisen. In fact, Pope Gregory VII sought to control this very same movement in 1074 by calling for the milities Christi, or knights of Christ to go to the aide of the Byzantine Empire. According to Riley-Smith, there was no apparent difference between the movement proposed by Pope Gregory VII and Urban II; accept the fact that it was now popular, twenty years later. The council in Clermont inspired the churchmen that were present, but in using a false sense of imagery, Pope Urban II essentially put these men in danger by presenting a very intricate set of ideas, in fundamentally simple terms. Nonetheless, it is said that the first bands of crusaders, mostly unskilled peasants and women left in the spring of 1096, before the order of Urban II, which was said to be on the Feast...

Nonetheless, it is said that the first bands of crusaders, mostly unskilled peasants and women left in the spring of 1096, before the order of Urban II, which was said to be on the Feast...

Bret Hart Essay Example | Topics and Well Written Essays - 1250 words - 1

Bret Hart - Essay Example This essay will flesh out the thesis that in Harte’s stories, there is manifest celebration of the virtues of the social underclass. Where literature was previously the preserve of the privileged and addressed to the same privileged audience, Harte broke this trend, and courageously at that, and highlighted the depth, effervescence and humanity of those in the fringes of society. Tennessee’s Partner is a great short story. At its core is the theme of friendship, if not unconditional love. Tennessee’s Partner (who was never referred by his actual name through the entire story) displays such an unconditional acceptance of his friend Tennessee that he soon withers and dies upon the latter’s execution. Even when his wife runs away with Tennessee, his partner doesn’t try to harm him. To the contrary, he welcomes him back home in all cordiality. This is all the more remarkable when one considers the livelihoods of these two characters. They are both petty criminals, often committing offenses against the law. It is natural to expect loose codes of friendship and loyalty among people who are considered criminals. Yet Tennessee’s Partner shows such dedication toward the wellbeing of his friend. In what is a brilliant symbolic touch, the very naming of the story as Tennessee’s Partner indicates the strength of unity of identit y of these two loyal friends. The reference to an individual solely through his friend’s name is a statement of the strong intertwinement of their two identities. Similarly, consistent with Harte’s reputation of being a brave writer who pushed the frontiers of social sensibility, there are sufficient hints at a homosexual relationship between the two lead characters. Perhaps fearing public outrage (as homosexuality was taboo during Harte’s era) the author might have only conveyed the intimate nature of their relationship via indirect literary means. Another way of looking at this is that Harte has

Writing Assignment # 1 - Essay Example One of the factors that reduce diabetes type 2 is physical activity; however, the researchers had also made observations that coffee consumption further reduced the incidences of high blood glucose levels. This was the major reason for this study. The researchers formulated a hypothesis to give a tentative explanation of what they had observed. The researcher hypothesized that regular consumption of coffee lowers the risk of developing diabetes type 2 conditions. This came in the mind of the researcher after observing that there were few or no cases of this condition among those people who consume coffee regularly. The experiments were necessary to prove right or wrong the researcher’s hypothesis. The hypothesis that the researcher made was testable and also addressed a specific point. The next scientific method that was used in this study was testing the hypothesis that the researcher formulated earlier. The researcher arranged an experiment to test the hypothesis. In the experiment, black canned coffee was used after being diluted with water. Concentrations of various components of coffee were determined for example caffeine was 290 mg/l, chlorogenic acid was 190 mg/l, and trigonelline was 230 mg/l. The animals that were used in this experiment were male KK-A each four weeks old. All animals were maintained in the same controlled conditions of temperature and humidity to ensure that different environmental conditions do not affect the results of the experiment. The animals were left to access water and standard laboratory food three days prior to the experiment. The composition of the foods that the mice accessed in the laboratory was proteins, non-nitrogenous foods, crude ash, crude fiber, energy, and sufficient minerals and vitamins to ensure that the health o f the mice was maintained (Yamauchi, 2010). To test the hypothesis two experiments were performed. In the first experiment, mice were separated into two categories. The first group

Entry form into United World College - Essay Example In my quest to discover how societies evolved and mankind developed, I would like to visit Peru’s Canal, one of the seats of modern civilization. I am adventurous by nature and history being my strongest interest, I would love to skydive someday or go on a wild trek through the forests of the Amazon. As a child I often used to reflect on the war horror stories and it always made me sad. I could feel the agony of the children who tested HIV positive, I could sense the insecurity that the mentally challenged face day after day. It was disturbing to see small street children having to work for their daily bread when they should be going to school. I used to wonder if there was anyway that the world could share a common goal – to erase poverty and sufferings, if there was anyway that I could contribute my time and talent towards achieving this goal. I wanted to do something different that would make me stand out from the rest, but I did not exactly know how to go about it, what avenues to explore to fulfill my dreams. I had read a lot and knew the power that words and love has. I had heard of Vasudeva Kutumbakam, an Indian phrase which literally means the world is one family. This phrase made a deep impression on my mind so much so that I started praying to God to really make the world one big family, to awaken the consciousness of those constantly at war. I started praying for world peace. My longing for world peace has ignited a burning desire into me to participate in an anti-war march someday, my own little way to make a difference. In my pursuit for a college for higher studies, I came across United World College and was immediately attracted for two reasons – one – students from more than 80 different nations study at the college at any given time. Secondly, community service plays a central role in all the colleges. I instantly made up my mind that this was the place for me. I was particularly drawn to Mahindra United World College of India as

On Passion and Self-Growth - Essay Example The American novelist, literary-critic, and story-teller Elizabeth Hardwick highlights that "The greatest gift is a passion for reading. It is cheap, it consoles, it distracts, it excites, it gives you knowledge of the world and experience of a wide kind. It is a moral illumination." I strongly believe in her statement as my journey in life has been filled with notable experiences derived from reading various books. Before my passion for reading is developed, I must admit that I was first obsessed in the stories my mom untiringly tells me before retiring to bed. Then, the exciting part of deciphering the meaning of the simple words on my earliest books came. Before I know it, I have become a voracious reader whose interests range from culture, sociology, and literature. Reading has sparked my curiosity and invites me to seek the mysteries of life. My passion for reading has hugely enhanced my intellect. Whenever I open a book, I often see myself unlocking a treasure box which will brings me into other places, provides me a glimpse of other culture, and conveys me a wealth of knowledge. It is amazing to know that every book shares its unique story. No matter how simple, each book offers and adds new ideas. Reading has enriched my intellect by bringing me to the world of Shakespeare, Milton, Julius Cesar and even as far as Aristotle's and Homer's. Reading introduced me to the radical ideas of Karl Marx, the different worlds explored by Gulliver, and the persistence of Helen Keller. Books broaden my horizons by adding new words to my vocabulary, polishing my grammar, and enabling me to find ways to communicate my ideas. My passion for reading enlightens me with knowledge and ushers me from the darkness of ignorance. Reading a book the second or third time does not diminish the knowledge that it offers. Being a passionate reader, I have discovered that it is not the writer which conveys and creates meaning in his or her compositions but in fact, the reader constructs his own comprehension on the material being strongly influenced by his background and experiences. Thus, I never really get tired of reading a single book over and over again as the knowledge it imparts vary each time. Aside from shaping me intellectually, reading also further my emotional development. As a thinking and feeling being, a story moves me and fills me with different kinds of emotion. I believe that the most important thing that my passion for reading brought me is the capability to understand the emotions of other people. Reading often requires empathy and putting one's self in the character's shoes. With this, I have developed the ability to accept, understand, and share the joys and sorrows of the people around me. I credit to my passion to reading the rapport I maintain with my social circles. I can say that my passion for reading is the largest contributor to my personal development. Books enrich and stimulate my mind while keeping me in touch with my emotional side. Reading has taught me the greatest lessons in life. I must stress that Denis Diderot identifies only great passions which can elevate the soul to great things. Considering all the things that my passion for reading accomplished in me, then, I can say that it must be the greatest passion a human can be blessed

World Economy Essay Example | Topics and Well Written Essays - 1500 words

World Economy - Essay Example Certain pressures are being exerted on nation- specific factors by this global phenomenon, and left in its trail are transformations in the economy. Any organization that wishes to compete globally and maintain its relevance in the international scene must necessarily be involved in strategic planning. It is also a truism that there has been a rise in the importance of worldwide relations both in quantitative and qualitative terms. These global factors have led to an increase in the flow of information, knowledge, commodities and capital among nations. Liberalisation is another way of defining these shifts in the global economy, many economies of the world today have opened up their economic space rather than being conservative, as was the practice in the pre-globalization years. Governments are reviewing their economic system in line with today's global realities. In a bid to be relevant in today's world, alignments and re-alignments have taken place and continue to take place globally. The evolution of the European Union is one major reference point in this regard. It is important to note that in a capitalist economy, also known as a free-market economy; where the means of production belongs to private individuals or firms; there has been a dramatic change in the mode of operation of these firms. Ordinarily within a domestic economy, organ... Within a domestic economy, the kind of questions business organizations face are usually of the kinds listed below: 1.What products or services does the organization intend to sell 2.Where and how will the organization manufacture these products or services 3. Where and how will the organization sell these products and services 4. Where and how will the organization acquire the resources 5. How does the organization expect to outperform its competitors These fundamental questions have usually helped organizations in the management of a business. The process of answering these questions however becomes more complex when considered in the light of the realities of globalization. Many other factors must of necessity be put into consideration, factors such as varying languages, cultural diversities, differences in economic systems, financial market situations, fluctuations in foreign exchange, legal restrictions, low literacy levels etc. Despite these odds, more and more firms have adopted international management principles to properly position them in the global market place engendered by the ever-increasing trade liberalisation sweeping across the globe. Consequently, businesses are being developed to meet specific needs. Businesses today tend to centralize the authority and responsibility under one key individual thus providing a central point of control for the total flow. Under this arrangement, it is easier to look up to one central point for answers and action. This eliminates buck-passing. Furthermore, organizations today have imbibed personnel development. This is because it helps the personnel involved to gain familiarity of the global market place thereby increasing their opportunity for

Indian Business Environment Essay Abstract One of the major objectives of Indian banking sector reforms was to encourage operational self-sufficiency, flexibility and competition in the system and to increase the banking standards in India to the international best practices. The second phase of reforms began in 1997 with aim to reorganization measures, human capital development, technological up-gradation, structural development which helped them for achieving universal benchmarks in terms of prudential norms and pre-eminent practices. This paper seeks to determine the impact of various market and regulatory initiatives on efficiency improvements of Indian banks. Efficiency of firm is measured in terms of its relative performance that is, efficiency of a firm relative to the efficiencies of firms in a sample. Data Envelopment Analysis (DEA) has used to identify banks that are on the output frontier given the various inputs at their disposal. The present study is confined only to the Constant-Return-to-Scale (CRS) assumption of decision making units (DMUs). Variable returns to scale (VRS) assumption for estimating the efficiency was not attempted. It was found from the results that national banks, new private banks and foreign banks have showed high efficiency over a period time than remaining banks. II. Reforms and Banking system In the post liberalization-era, Reserve Bank of India (RBI) has initiated quite a few measures to ensure safety and consistency of the banking system in the country and at the same point in time to support banks to play an effective role in accelerating the economic growth process. One of the major objectives of Indian banking sector reforms was to encourage operational self-sufficiency, flexibility and competition in the system and to increase the banking standards in India to the international best practices 4. Although the Indian banks have contributed much in the Indian economy, certain weaknesses, i.e. turn down in efficiency and erosion in profitability had developed in the system, observance in view these conditions, the Committee on Financial System(CFS) was lay down. Reserve Bank of India has implemented banking sector reforms in two phases. The first reform focused on introduction of several prudential norms, major changes in the policy framework, and formation of competiti ve atmosphere. The second phase of reforms began in 1997 with aim to reorganization measures, human capital development, technological up-gradation, structural development which helped them for achieving universal benchmarks in terms of prudential norms and pre-eminent practices. The Financial sector reforms were undertaken in 1992 based on the recommendations of the CFS. Later, The Narsimham Committee has provided the proposal for reforming the financial sector. The committee also argued that ‘economic reforms in the real sector of economy will, however, fail to realize their full potential without a parallel reform of the financial sector. It focused on several issues like, releasing of more funds to banks, deregulation in interest rates, capital adequacy, income recognition, disclosures and transparency norms etc. However, financial sector reforms focused on improving the competitive efficiency of the banking system. The financial reform process has commenced since 1991 which was made the banking sector healthy, sound, well- capitalized and become competitive. The competitive pressures to improve efficiency in the banking sector has resulted in a switch from traditional paper based banking to electronic banking, use information technology and shift of emphasis from brick and mortar banking to use of ATMs. INDIAN BUSINESS ENVIRONMENT IN BANKING INDUSTRY Indian banking industry, the backbone of the country’s economy, has always played a key role in prevention the economic catastrophe from reaching terrible volume in the country. It has achieved enormous appreciation for its strength, particularly in the wake of the worldwide economic disasters, which pressed its worldwide counterparts to the edge of fall down. If we compare the business of top three banks in total assets and in terms of return on assets, the Indian banking system is among the healthier performers in the world. This sector is tremendously competitive and recorded as growing in the right trend (Ram Mohan, 2008). Indian banking industry has increased its total assets more than five times between March 2000 aThe overall development has been lucrative with enhancement in banking industry efficiency and productivity. It should be underlined here is financial turmoil which hit the western economies in 2008 and the distress effect widened to the majority of the other countries but Indian banking system survived with the distress and showed the stable performance. Indian banks have remained flexible even throughout the height of the sub-prime catastrophe and the subsequent financial turmoil. The Indian banking industry is measured as a flourishing and the secure in the banking world. The country’s economy growth rate by over 9 percent since last several years and that has made it regarded as the next economic power in the worldnd March 2010, The Indian banking industry is measured as a flourishing and the secure in the banking world. The country’s economy growth rate by over 9 percent since last several years and that has made it regarded as the next economic power in the world.

Liberalisation of India’s banking sector †¢ Liberalisation of India’s banking sector begun since 1992, following the Narasimhan Committee’s Report (December 1991) †¢ Important recommendations of the Committee were – [i] reduction of statutory pre-emptions (SLR and CRR) [ii] deregulation of the interest rates [iii] opening up the sector to foreign and domestic private banks [iv] adoption of prudential regulations relating to capital adequacy, asset classiï ¬ cation and provisioning standards Service firms such as ITC Hotels and ANZ Grindlays Bank found direct marketing very effective in retailing customers and weathering competition. †¢ The Indian banking system is growing in a robust manner. †¢ The Indian banking system complies with international standards of prudential regulation. †¢ The Indian banking system is opening up for entry of foreign banks. †¢ Despite the growth, Indian banking system is not entirely inclusive. †¢ There is good opportunities for the banking industry – domestic and foreign – for expansion to ï ¬ ll the gap. A decade after the Narasimham report was published and in the light of new challenges from the norms laid down by the WTO and Basel II, it is imperative to have a close look at the performance of banks in the last decade or so to assess the success of the reform process. INDIA inherited a very weak banking system following Independence. However, the nationalisation programme (1969) helped this sector achieve remarkable success in many respects. The stability among depositors, penetration into rural India and the consequent reduction in poverty and diversification out of agriculture were some of its laudable achievements. Given the predominantly bank based nature of financial system, the banking industry gained the reputation of one of the most protected in the country. However, in the 1990s a chain of events such as introduction of modern technologies, competition from new players in the liberalised market place, and enhanced emphasis on governance to protect shareholder interest changed the way banks conducted business. The Indian banking sector with its diversity of ownerships — State Bank of India and its associates, nationalised banks, private domestic banks and foreign banks also faced a similar set of challenges. Although the public sector banks acquired a dominant presence thanks to the regulatory environment, several of them performed poorly in the late 1980s. To preserve the soundness of the financial system, especially the banking segment, the Government set up the Narasimham Committee. The Committee (in 1991) made far-reaching recommendations that formed the basis of banking reforms. Some of the comprehensive reform measures suggested included: Stricter income recognition and asset classification, higher capital adequacy ratio, phased deregulation of interest rate, lowering statutory liquidity ratio (SLR) and cash reserve ratio (CRR), entry deregulation, and branch-de-licensing. These measures mainly aim to improve the efficiency/profitability of banking industry. A decade and half after the Narasimham report was published and in the light of the World Trade Organisation and Basel II norms, it is imperative to have a close look at the performance of banks in the last decade or so to assess the success of the reform process. Performance indicators Commonly-used measures to assess the performance of the banking industry are: Return on Asset (ROA), Operating Profit Ratio (OPR), Net Interest Margin (NIM), Operating Cost Ratio (OCR) and Staff Expenditure Ratio (SER). The first two are generally considered profitability measures, while the others, the efficiency indices. These five measures have been considered in this analysis for two sub-periods: Pre-liberalisation (1992-1995) and post-liberalisation (2000-2003). The total number of banks considered for two sub-periods were 64 (eight State Banks, 19 nationalised banks, 19 private banks and 18 foreign banks) and 87 (8, 19, 28 and 32 respectively). Overall performance improvement A comparison of performance indices during the study period reveals that the reform measures helped to improve the overall performance of industry. This is reflected in the improvement of all performance indicators barring the net interest margin (see Table). Interestingly, the ROA, treated as a proxy for risk-adjusted return, increased from (-) 0.28 per cent in the pre-liberalisation period to 0.79 per cent (against more than 1 per cent in other merging markets such as Singapore, Malaysia and Korea) post-liberalisation, indicating a significant rise in the ability of banks to convert their assets into net earnings. Another interesting aspect is that despite a marginal fall in the net interest margin from 2.84 to 2.73 (which might be due to policy change), the banking industry has managed to improve its OPR by increasing its non-interest fee-based income and reducing its operating costs/staff expenses. The evidence indicates that after the reform initiation period, the banks have increasingly been providing off balance sheet items such as derivatives, which generate major part of non-interest income. The proportion of operating costs/staff expenses has declined mainly due to computerisation and the voluntary retirement scheme. The property rights theorists believe that the private banks are more efficient than their counterparts in the public sector. This view is corroborated by the public choice theorists who argue that the specific X inefficiency factors are more prevalent in the public sector, irrespective of market conditions. Further, many cross-country findings report an increased government ownership as a deterrent to the development of the banking system. The Indian banking scenario seems to be consistent with the above, as the privately owned (foreign as well as domestic) banks seem to be superior to their public counter parts with respect to all performance indicators except the NIM. Despite a fall in their OPR and NIM between 1992-95 and 2000-03, the private banks successfully managed to reduce their operating expenditures, particularly the staff expenditures, thereby successfully maintaining their status. Among private banks, the foreign banks seem to be superior in terms of three out of five the criteria used. Within the public domain, the State Banks tend to be superior with respect to ROA, OCR and SER, while the nationalised banks seem to show better performance in terms of OPR and NIM. Thus, although there is a significant improvement in the overall performance of banks as one moves from the post-reform period to the late-reform period, one finds certain anomalies such as a fall in the NIM (except in the case of the nationalised banks), a fall in the ROA of private domestic banks, a reduction in the OPR of private domestic and foreign banks and a rise in the OCR/SER of foreign banks. Convergence or divergence Apart from the overall improvement across the board, another important criterion to evaluate the success story is to check whether the competitive force has led to any convergence in the performance of different ownership groups in the post-liberalisation period. Exposure to the competitive forces is often argued as a panacea to shake poorly performing banks out of their slumber. Although the public banks compared poorly with private banks during the initial period, they made a significant improvement in the later period by responding well to the new challenges of competition and consolidation, mostly following a gradual and cautious approach. The pay off is well reflected in the increase in their ROA, OPR and NIM. Some possible reasons for the better performance of public banks could be they still undertake most of the government borrowing programmes, thereby generating significant fee based income; the market discipline imposed by the listing of most public sector banks has also probably contributed to this improved performance; and ï‚ · the reform measures have changed their business strategies particularly greater diversification of non-fund based business and emergence of treasury and foreign exchange business. The study reveals that the OPR across four ownership groups tend to converge. The NIM tend to converge across private and public sectors while the OCR continues to remain significantly different across ownership groups. The above analyses indicate that the banking sector performs reasonably well with respect to the goals set by the Narasimham Committee, particularly in the context of the poorly performing banks and showing some encouraging signs to meet the Basel II norms by 2006. However, one should not go over board in reading these numbers to evaluate the success of the Indian banking sector, particularly from the perspective of a developing economy such as ours. Policy-makers should be extra cautious in giving free a reign to the banking sector in pursuing profit and risk based strategies. Recent trends in non-synergy based consolidation, growing disinclination to lend money towards productive purposes and to the unprofitable sectors such as agriculture, self-help groups, infrastructure and to small and medium sized enterprises, its growing engagement in non-productive treasury operations and conspicuous consumer lending will seriously impair the role of banks as public instruments of development. Therefore, maintaining a balance between these two objectives will remain a challenge to the banking sector for some time to come.

The Current Approaches To Ecotourism

The Current Approaches To Ecotourism Ecotourism has been the fastest growing segment of the global tourism industry and has developed on the tourism market within the core of environmental movement as well as becoming continuously important in the tourism industry (Matei, 2011). However, before ecotourism is emerged, tourism has been rapidly become one of the most important part of economic growth in the world. While tourism has been contributed to the source of economic development, conventional mass tourism growth has resulted in the numerous negative impacts on tourism destination, such as the destruction of ecological systems, loss of cultural heritage, cultural commodification and inter-cultural conflict (Weaver, 2008; Lansing Vries, 2007). In late 1980s, the realization of these problems has led to the development of sustainable tourism (Hugo, 2010). Sustainable tourism has been on the basis of responsible travel to natural areas that preserve the destinations environment and has reminded as a type of tourism, wh ich positively contributes to visitor satisfaction, incorporates an element of environmental education, delivers benefit to poor local communities and also assists the local communities to maintain their cultural features (Matei, 2011). Additionally, sustainable tourism is regarded as the role of marketing tool to promote and advertise any form of tourism associated with nature based and also the money from sustainable tourism is reinvested in order to environmentally protect and preserve tourism destination as well as significantly develop the access of the local people to jobs creation and civilization (Matei, 2011). In addition, these new forms of tourism are proposed to simultaneously fulfill the needs of different parties involved, such as delivering revenues and profits to the tourism industry, responsible travel experiences to the increasingly wealthy tourist and economic growth combined with environmental and socio-cultural protection to host countries and communities (Lansi ng Vries, 2007). As a result of this reason, many countries have considered of sustainable tourism, which is meant by a travel to natural destinations (remote areas) under environmental protection at the international, national, regional or private level (Honey, 2008). Current Approaches to Ecotourism The core current approaches to ecotourism development are suggested two ideal types of the approaches in relation to the level of sustainability outcomes. Those approaches are comprehensive approach and minimalist approach. The first ideal type of the approaches to ecotourism is minimalist approach. The minimalists approach emphasizes a basic or shallow understanding and learning opportunities based on elemental perspective. An elemental approach is evident at the other end of the continuum when a product focuses on specific non-captive animals or plants that are deemed to be particularly attractive or interesting, such as charismatic megafauna or megaflaora a (Weaver, 2005). In contrast, the other ideal type of the approaches to ecotourism is comprehensive approach which adopts a holistic perspective on the product that incorporates the ecosystem into associated human influences so that the implication of cultural component is more likely to be integrated into the interpretive exper iences than recognized as attraction (Schianetz, Kavanagh Lockington, 2007). The minimalist approach does not intentionally have desire for transforming values or behavior and its approach to sustainability is associated with site-specific, status quo oriented as well merely as natural environment (Weaver, 2005) whereas the comprehensive approach is purposed to enhance deep understanding and deliberately transform participant attitudes and behavior (Schianetz, Kavanagh Lockington, 2007). Furthermore, according to Weaver (2005), it is believed that the implementation of the comprehensive approach utilized by the managers in destinations is more likely to provide the objectives of environmental and sociocultural sustainability to tourism destinations. By fostering a more environmentally aware and activist market, comprehensive approach is conducive to the development of the product that benefits from donations and eagerness to engage in volunteer activity such as research assistance, and informal policing. When the comprehensive approach combines with the emphasis on enhancement based global and environmental and sociocultural enhancement, the volunteer activity for the rehabilitation and reclamation of habitat, which has been considerably transformed by human activity is channeled though the opportunity emerged. By contrast, according to Weaver (2005), the minimalist approach may hinder the attainment of the sustainability objectives. Therefore, the problems of the mi nimalist approach is mainly likely to be occurred from the element approach to construct species hierarchies, and thereby charismatic megafauna is more likely to be highly assessed by the managers but is not less ecologically valuable species. However, its attention will be able to ironically become damaging consequences to the charismatic megafauna by encouraging prolonged intrusive contact with humans. Generally, the process of observing wildlife is more likely to result in subtle negative effects by carrying out an inadvertently inappropriate manner. From a sustainability perspective that is global enhancement within a combined environmental, sociocultural and economic that includes local community, both minimalist and comprehensive approach appear to fulfill the imperatives of financial sustainability and high levels of satisfaction (Schianetz, Kavanagh Lockington, 2007). Examples of Ecotourism Two-ecotourism case study have been identified and analyzed. The first ecotourism case is Sumba Island in Indonesia. The remote island of Sumba is one of the poorest islands in Indonesia although Sumba Island is culturally one of the richest islands with very strong ancient tradition and strong heritage (The Sumba Foundation, 2012). In Sumba Island, most of the residents live without access to clean water, basic health care and education and also malnutrition is among the highest in the world (The Sumba Foundation, 2012). Nihiwatu has become a major employer of villagers in Sumba Island and the purpose of Nihiwatu is to develop the quality of life for it Sumbanese neighbor throughout responsible tourism (Nihiwatu, 2012). The main stakeholders are eco resort villages that obtain a large amount of funding from guest vacationing in order to support the local community projects by donating (Nihiwatu, 2012). Nihiwatu as an eco resort has commenced local community development projects and has closely cooperated with The Sumba Foundation to take the projects to a higher level (Nihiwatu, 2012). The projects are in relation to creating sustainable livelihood and jobs, achieving energy efficiency and adequate supply, food and water supply. The project makes peoples lives clearly visible so health and local welfare has been changed much better and the hygiene conditions of clinics and villages are significantly improved (The Sumba Foundation, 2012). From the projects perspective, Nihiwatu eco resort has importantly taken the concepts of sustainable development. The resort has considered of local residents neighbors by having responsibility so after purchasing land, the landowner has taken not only the land, but also the responsibility of taking care of the land and its society (Nihiwatu, 2012). Moreover, Nihiwatu eco resort has become one of the merely hotels in the world which utilize 100% powered by bio-fuel and renewable energy source as well as recycling everything so that carbon emission which results in climate change has been decreased (Sumba, 2012). Eco resort village in Sumba Island culturally and socially influences on young generation. The value of frequent informal interaction with tourists is likely to afford the opportunities to practice English skills and also to experience adverse social cultural impacts associated with ecotourism, which is concerned with the impact on young generation conduct between unappreciated sexual conduct and consumption alcohol that is vastly different from their culture (Clifton Benson, 2006). Furthermore, the economic benefit associated with eco resort village tourism provides the optimism in regard to income generating opportunities, which derive from direct employment, rental of accommodation for tourists or the sale of handicrafts and food (Clifton Benson, 2006). It is seen that the rental of accommodation has economically generated the benefits for the wide local communities because the accommodations has been owned and operated by the local residents as well as having been built specifi cally for the purpose. In addition, the sale of handicrafts and food has provided the opportunity to participation in to a greater variety of individuals and groups, such as women, the young and old members of the local communities (Clifton Benson, 2006). Consequently, this eco resort village is fundamentally important for residents life so if the village culture is damaged, the residents will be ruined. This benefits related with village ecotourism is likely to be regard as both reflecting and reinforcing social capital in the local communities (Clifton Benson, 2006). The second ecotourism case is Song Saa Private Island in Combodia. Song Saa Private Island is officially known as Koh Bong and Koh Quen and has renown for the rich and diverse marine life in their surrounding waters (Song Saa, 2012). Song Saa Private Island integrates commercial development with the triple bottom lines of ecological (biophysical), social and economic sustainability by emphasizing on sustainability and high exemplary environmental standards (Song Saa, 2012). The relevance of the triple bottom-line concept and sustainability approach are the central to the purpose and mission statement of Song Saa private Island so as to improve the environment, the condition of local communities and the economy (Song Saa, 2012). Song Saa Private Island positively or negatively influences on environment in terms of water, energy, solid waste, biodiversity, pollution and contamination. According to the report (Sustainable Management Plan, 2012), Water discharged from Song Saa Private Is land, such as grey-water, sewage and storm-water sources results in damage to local wildlife and ecosystems and alteration of water has negative impact on human communities and local ecosystems. The inefficient use of energy has increased carbon in the atmosphere and contributed to global warming (climate change). Solid waste inflows have negative impact on local flora and fauna and associated habitats. Construction and operation of the resort and guest and staff activities have an adverse impact on local biodiversity by destroying, displacing or stressing animals, vegetation or their associated ecosystems. Physical, visual and ambient pollution detracts from amenity, intrinsic and cultural values of the landscape and the environment. Chemicals (cleaning products, insecticides, chlorine herbicides), guest and staff sunscreens, insect repellants result in damage to reef systems. In addition, Song Saa Private Island also has negative or positive effects on social cultural and economic based on the local communities. Song Saa Private Island provides the opportunities throughout the local community program and conservation program to weave together the needs of local peoples (Sustainable Management Plan, 2012). These programs focuses on the support communities throughout activities that promote sustainable livelihoods and the process which create enabling conditions that generate local welfare. This development of the projects is fundamentally based on working with government and community institutions, networks and norms to achieve tangible and positive outcomes (Sustainable Management Plan, 2012). Song Saa community and conservation program provides the development of educational opportunities for the local villagers so that local people increase their awareness and understanding of environmental issue and opportunities; increasing the knowledge and understan ding of marine conservation among the inhabitants of local fishing village (Song Saa Conservation and Community Program, 2012). Furthermore, the conservation and community projects efficiently manage the flow of solid waste from the villages. This management provides an income stream through the provision of incentive payments to the village waste collectors and an additional income stream though the sale of recyclable materials for the local community when the solid waste and recycle management contributes to the health of the village (Song Saa Conservation and Community Program, 2012). Song Saa Private Island has participated in the water system, which is established for local community health as a core component of sustainable livelihood maintenance throughout the provision of safe domestic water supply and the protection of water supply from contamination. The water system works with the local community and local providers to improve environmentally sensitive water treatment and waste reticulation system so as a result of the water systems, local community is given an effective water management and unique livelihood activities such as snail and frog rearing (Song Saa Conservation and Community Program, 2012). Ecotourism the Ideal versus the Real In order to establish sustainable tourism development, the strong interaction between environment and human must need. However, it is not easy to fulfill and assess the sustainability of tourism destination because of the complex conduct and the use of the variety approaches, which are in possession of different strengths and weaknesses depending on the characteristics of the tourism destinations. Therefore, it is necessary to understand the available approaches and use its correct usage in order to develop sustainable tourism. The possible approach to develop sustainable tourism development needs to be carefully considered of the positive impact on the relationship between economic, social cultural and environment component within the triple bottom line approach. The triple bottom line approach requires the balance of three components (ecological, economic and social) in order to generate sustainability to the tourism development. As described two ecotourism cases, the triple bottom line is basically associated with sustainability so if the ecotourism development and products do not carefully consider of three components, one of components will gain damage by unbalancing three components. For example, if tourism development is more likely to provide the benefit to the tourists without any concern about environment in the destinations, the environment in the destinations will suffer from tourists activity. In addition, local community and culture will be also damaged by visiting tourists if not considered of local environment and culture when the tourism develops. The local culture may be probably changed by direct or indirect impact from tourist behavior and attitude toward local community. Although by contacting with tourists, the positive or negative different culture is likely to come into local community, the problem is that the local community will not be able to conserve. Therefore, in order to protect and prevent these potential problems in the tourism destinations, comprehensive approach is more likely to be appropriate for the current sustainable tourism development than minimalist approach because comprehensive ecotourism considers nature-based and cultural as the attractions as well as global, environmental and sociocultural enhancement for sustainability. For example, minimalist ecotourism focuses on particular species so this approach is easy to provide the greater tourist satisfaction but the approach is less likely to contribute to the development of local community and culture without changes. However, comprehensive approach tends to have the more positive impacts on both environmental and local community in terms of economic, social culture and ecological because of the broader attractions (including nature-based and culture), deep understanding and learning of the tourism destinations. So, this approach will be reasonably utilized as an ap preciate approach according to the characteristic of the tourism destinations and the needs of environment and local community in regard of ecological, social cultural and economic. Conclusion Ecotourism is the biggest movement among tourism industry and also has been rapidly growing up in global tourism industry. Sustainable tourism development associated with ecotourism is regarded as the important tourism approach to tourism destinations in the world. With sustainability approach, the tourism destinations have been significantly considering of environmental and socio cultural protection. This big movement directly or indirectly influences on environment and local community and culture in the tourism destination. Consequently, the accurate approaches toward the tourism development and products are considerately required according to the characteristic of the tourism destinations in order to sustain the tourism development.

Odyssey Hospitality Essay -- Essays Papers

Odyssey Hospitality Hospitality In The Odyssey by Homer, hospitality plays a very important role. There are certain rules of hospitality needed, such as inviting a stranger into your home, not asking them their name before they have dined at your table, and sometimes even gift offerings. If these rules of hospitality are not carried out, the consequences are very severe. Hospitality is to be given to all by all. Being a good host is very important in The Odyssey, even to the gods. It is a sign of respect for all no matter where they are from or how poor they appear to be. This means that as soon as you see a stranger, you invite them into your home to sit at your table just as king Nestor did. "As soon as they saw the strangers, all came crowding down, waving them on in welcome, urging them to sit." (III, 38) After you have invited them into your home, you must invite them to dine at your table. Only after they have dined, you have the permission to ask for their names, like King Menelaus did, "'Help yourselves to food, and welcome! Once you've dined we'll ask you who you are.'" (IV, 68-69) Many times before dining "...women had washed them, rubbed them down with oil and drawn warm fleece and shirts around their shoulders..." (IV, 56-57) If the host enjoyed the company of the guests, many times they will honor them with gifts. The kind of gifts given varied depending on the wealth and generosity of the host. For example, Aeolus, the king of the winds, gave Odysseus a...

Spatial Filtering Fundamentals

4/28/2008 Spatial filtering fundamentals by  Gleb  V. Tcheslavski:  [email  protected] lamar. edu http://ee. lamar. edu/gleb/dip/index. htm Spring 2008 ELEN 4304/5365 DIP 1 Mechanics of spatial filtering Considering frequency domain filtering, the effect of LPF applied to an image is to blur (smooth) it. Similar smoothing effect can be achieved by using spatial filters (spatial masks, kernels, templates, or windows). We discussed that a spatial filter consists of a neighborhood and a pre-defined operation performed on the image pixels defining the neighborhood.The result of filtering – a new pixel with coordinated of the neighborhood’s center and the value defined by the operation. g y p If the operation is linear, the filter is said to be a linear spatial filter. Spring 2008 ELEN 4304/5365 DIP 2 1 4/28/2008 Mechanics of spatial filtering Assuming a 3 x 3 neighborhood, at any point (x,y) in the image, the response of the spatial filter is g ( x, y ) = w(? 1, ? 1 ) f ( x ? 1, y ? 1) + w(? 1, 0) f ( x ? 1, y ) + †¦ + w(0, 0) f ( x, y ) + †¦ + w(1,1) f ( x + 1, y + 1) Filter coefficient Pixel intensity In general: g ( x, y ) = s =? a t =? b ? ? w(s, t ) f ( x + s, y + t ) a bSpring 2008 ELEN 4304/5365 DIP 3 Mechanics of spatial filtering Here a mask size is m x n. m = 2a + 1 n = 2b + 1 Where a and b are some integers. For a 3 x 3 mask Spring 2008 ELEN 4304/5365 DIP 4 2 4/28/2008 Spatial correlation and convolution Correlation is a process of moving the filter mask over the image and computing the sum of products at each location as previously described. Convolution is the same except that the filter is first rotated by 1800. For a 1D case, we first zeropad f by m-1 zeros on each size. We compute a sum of products in both cases†¦ Spring 2008 ELEN 4304/5365 DIP 5 Spatial correlation and convolutionCorrelation is a function of displacement of the filter. A function containing a single 1 with the rest being zeros is g g g called a d iscrete unit impulse. Correlation of a function with a discrete unit impulse yields a rotated version of a function at the location of the impulse. To perform a convolution, we need to pre-rotate the filter by 1800 and perform the same operation as in correlation. Spring 2008 ELEN 4304/5365 DIP 6 3 4/28/2008 Spatial correlation and convolution In a 2D case, for a filter of size m x n, we pad the image with m-1 rows of zeros at the top and bottom and n-1 columns of zeros on the left and right.For convolution, we pre-rotate the mask and perform the sliding sum of products. Spring 2008 ELEN 4304/5365 DIP 7 Spatial correlation and convolution Correlation of a filter w(x,y) of size m x n with an image f(x,y) is w( x, y ) f ( x, y ) = s =? a t =? b ? ? w(s, t ) f ( x + s, y + t ) ? ? w(s, t ) f ( x ? s, y ? t ) a b a b Convolution of a filter w(x,y) of size m x n with an image f(x,y) is w( x, y ) ? f ( x, y) = s =? a t =? b Spring 2008 ELEN 4304/5365 DIP 8 4 4/28/2008 Vector representatio n of linear filtering It is convenient sometimes to represent a sum of products asR = ? wk zk = w T z k =1 Filter coeffs Image intensities mn For example, for a 3 x 3 filter: p , R = ? wk zk = w T z k =1 Spring 2008 ELEN 4304/5365 DIP 9 9 Generating spatial filter masks Generating an m x n linear spatial filter requires specification of mn mask coefficients. These coefficients are selected based on what the filter is supposed to do keeping in mind that all we can do with linear filtering is to implement a sum of products. Assuming that we need to replace the pixels in an image with the average pixel intensities of a 3Ãâ€"3 neighborhood centered on those pixels.If zi are the intensities, the average is R= 9 1 9 ? zi 9 i =1 Which is: R = ? wi zi = w T z; i =1 ELEN 4304/5365 DIP wi = 1 9 10 Spring 2008 5 4/28/2008 Smoothing spatial filters Smoothing filters are used for blurring and noise reduction. Blurring may be implemented in preprocessing tasks to remove small details from an ima ge prior to large object extraction. The output of a smoothing (averaging or lowpass) linear spatial filter is the average of the pixels contained in the neighborhood of the filter mask.By replacing the value of every pixel in an image by the average of the intensity levels in the neighborhood defined by a filter mask, the resulting image will have reduced â€Å"sharp† transitions in intensities. Since random noise typically corresponds to such transitions, we can achieve denoising. Spring 2008 ELEN 4304/5365 DIP 11 Smoothing spatial filters However, edges (characterized by sharp intensity transitions) will be blurred. Examples of such masks: 1) A box filter – spatial averaging filter 3Ãâ€"3; 2) Weighted average filter – attempt to reduce blurring: g a g ( x, y ) = s =? a t =? b ? ? (s, t ) f ( x + s, y + t ) s =? a t =? b b ? ? w(s, t ) 12 a b Spring 2008 ELEN 4304/5365 DIP 6 4/28/2008 Smoothing spatial filters The effect of filter size.

Spring 2008 ELEN 4304/5365 DIP 13 Smoothing spatial filters Frequently, blurring is desired for ease of object detection: an original Hubble image, the result of applying a 15Ãâ€"15 averaging mask to it and the result of thresholding with a threshold of 25% of the highest intensity. Spring 2008 ELEN 4304/5365 DIP 14 7 4/28/2008Order-statistic (nonlinear) filters Order-statistic filter are nonlinear spatial filters whose response is based on ordering (Ranking) the pixels in the neighborhood and then replacing the value of the center pixel by the value determined by the ranking result. The median filters are quite effective against the impulse noise (salt-and-pepper noise). The median of a set of values is such that half the values in the set are greater than the median and half is lesser than it: Ex: the 3Ãâ€"3 neighborhood has values (10, 20, 20, 20,15, 20, 100, 25, 20 ). These values are ranked as (10, 15, 20, 20, 20, 20, 20, 25, 100).The median will be 20. There are also max and min filters.

Since averaging is analogous to spatial integration, we y g g g p g can assume that sharpening is analogous to differentiation in space. The derivatives of a digital function are defined in differences.The first derivative must be: 1) Zero in areas of constant intensity; 2) Non-zero at the onset and end of an intensity step or ramp; 3) Non-zero along ramps of constant slope. The second derivative must be: 1) Zero in areas of constant intensity; 2) Non-zero at the onset and end of an intensity step or ram p; 3) Zero along ramps of constant slope. Spring 2008 ELEN 4304/5365 DIP 17 Sharpening spatial filters: foundations The first-order derivative: ?f = f ( x + 1) ? f ( x) ? x The second-order derivative: ?2 f = f ( x + 1) + f ( x ? 1) ? 2 f ( x) ? x 2 It can be verified that these definitions satisfy the conditions for derivatives.Spring 2008 ELEN 4304/5365 DIP 18 9 4/28/2008 Sharpening spatial filters: foundations The circles indicate the onset or end of intensity transitions. The sign of the second derivative changes at the onset and end of a step of ramp. The second derivative enhances fine details much better than the first derivative. This is suitable for sharpening. Spring 2008 ELEN 4304/5365 DIP 19 Using the second derivative for image sharpening – the Laplacian We consider isotropic filters – the response is independent of the direction of the discontinuity in the image Such filters are image. rotation invariant.The simplest isotropic derivative operator is the L aplacian: ?2 f ? 2 f ? f = 2 + 2 ? x ? y 2 Therefore: ? 2 f = f ( x + 1, y ) + f ( x ? 1, y ) + f ( x, y + 1) + f ( x, y ? 1) ? 4 f ( x, y ) The Laplacian is a linear operator since derivatives are linear operators. Spring 2008 ELEN 4304/5365 DIP 20 10 4/28/2008 Using the second derivative for image sharpening – the Laplacian The Laplacian can be implemented by these filter masks Since the Laplacian is a derivative operator, its use highlights intensity discontinuities in the image and deemphasize regions with slow varying intensity levels levels.It tends to produce images having grayish edge lines and other discontinuities, and a dark, feature-less background. Spring 2008 ELEN 4304/5365 DIP 21 Using the second derivative for image sharpening – the Laplacian Background features can be preserved together with the sharpening effect of the Laplacian by adding the Laplacian image to the original. If the definition of the Laplacian has a negative central coefficient, the La placian image must be subtracted rather than added to obtain a sharpening result. In general: g ( x, y ) = f ( x, y ) + c 2 f ( x, y ) ? ? ?Output intensity Input intensity -1 – if the center is negative; +1 otherwise Spring 2008 ELEN 4304/5365 DIP 22 11 4/28/2008 Using the second derivative for image sharpening – the Laplacian The Laplacian Laplacian with scaling The original (blurred) image The image sharpened with mask 2 The image sharpened with mask 1 Spring 2008 ELEN 4304/5365 DIP 23 Unsharp masking and highboost filtering An approach used for many years to sharpen images is: 1. Blur the original image; 2. Subtract the blurred image from the original (the result is called the mask): g mask ( x, y ) = f ( x, y ) ? f ( x, y ) Original Blurred image 3.Add the mask to the original: g ( x, y ) = f ( x, y ) + k ? g mask ( x, y ) Here k is a weight. Spring 2008 ELEN 4304/5365 DIP 24 12 4/28/2008 Unsharp masking and highboost filtering When k = 1 – unsharp masking ; k > 1 – highboost filtering; k < 1 – de-emphasize the contribution of a mask. The shown intensity profile can be viewed as a horizontal scan through a vertical edge transition from a dark to li ht t a light region. i This approach is similar to Laplacian method.

The gradient vector points in the direction of the greatest rate of g (x,y). g (length) gradient change of f at location ( y) The magnitude ( g ) of g 2 2 M ( x, y ) = ? f = g x + g y Is the value of rate of cha nge at (x,y) in the direction of gradient. Spring 2008ELEN 4304/5365 DIP 27 Gradient method M(x,y) is an image of the same size as the original and is called the gradient image. Magnitude makes M(x,y) non-linear. It is more s itable in some applications to use: suitable se M ( x, y ) ? g x + g y For an image where z5 represent the pixel f(x,y) and z1 represent the pixel f(x-1,y-1), the simplest (Roberts) definitions for gradients are: M ( x, y ) = ( z9 ? z5 ) + ( z8 ? z6 ) 2 2 M ( x, y ) ? z9 ? z5 + z8 ? z6 However, Roberts cross-gradient operators lead to masks of even sizes, which is inconvenient. ELEN 4304/5365 DIP 28 Spring 2008 14 4/28/2008 Gradient methodThe smallest masks with central symmetry (ones we are interested in) are 3Ãâ€"3. The gradient can be approximated for such masks as following: ?f = ( z7 + 2 z8 + z9 ) ? ( z1 + 2 z2 + z3 ) ? x ? f gy = = ( z3 + 2 z6 + z9 ) ? ( z1 + 2 z4 + z7 ) ? y Therefore, the mask could be: gx = M ( x, y ) ? ( z7 + 2 z8 + z9 ) ? ( z1 + 2 z2 + z3 ) + ( z3 + 2 z6 + z9 ) ? ( z1 + 2 z4 + z7 ) Roberts operators They are Sobel operators.
