Alternative Dispute Resolution

Elective Dispute Resolution Free Online Research Papers Elective Dispute Resolution, alluded hereon as ADR, can be characterized as an aggregate portrayal of procedure or instruments that gatherings can use to determine questions as opposed to bringing a case through the conventional court structure. ADR is a piece of the common equity framework with the United Kingdom. It is a key part of the common equity framework and has become in the course of recent years. The issue being referred to will be to asses to contentions for and against the utilization of ADR in the Civil Justice framework. These options have been created to manage the apparent deficiencies of the conventional structure of law and court technique. The expanded significance of ADR has been motioned in both enactment and court methods. The utilization of ADR was included overwhelmingly in Lord Woolf’s Interim Report and his Final Report. In his last report, Lord Woolf asked that individuals ought to be urged to utilize the developing number of complaint procedures techniques, as ADR, before taking their cases through court procedures. ADR highlights noticeable in the new Civil Procedure Rules (CPR) 1998.Rule 1. (4.) (1) expresses that the court should promote the superseding objective by effectively overseeing cases. Rule1.4. (2) continues expounding twelve unique instances of what successful case the board implies. The fifth of these is to urge the gatherings to utilize ADR strategies if the court believes that to be proper and to encourage the utilization of such systems. Rule 26.4 of the CPR 1998 empowers judges either for their own or with the understanding of the two gatherings, to stop court procedures where they believe the question to be more qualified to arrangement by some elective methodology. In the event that in this manner a court is of the supposition that a contest could have been successfully settled through some elective system and this was brought to the consideration of the gatherings, at that point under Rule 45.5 of the CPR, the gathering demanding that the case be brought under the watchful eye of the court, might be punished by the court by granting them decreased or no expense should they win the case. This guideline is additionally outlined in R (Cowl) v Plymouth City Council [2001] CA. It is conceivable to decline to take part in ADR without consequently enduring in the honors of cost: Hurst v Leeming [2002]. There are various sorts of elective debate goals. These have been recognized in the Lord Chancellor Department 1998 Consultation paper as being-discretion; intercession; appeasement; drug arb; master assurance; early nonpartisan assessment; impartial actuality discovering; Ombudsmen and Utility Regulations. In any case, in light of the fact that the extents of the ADR systems are so wide, just the most well-known and generally utilized types of ADR will be considered in detail. The first and the most seasoned of the elective methods is intervention. This is the system whereby parties allude the issue to a third for goals, as opposed to taking the case to the conventional courts. The judge must be unbiased, this implies, he/she should not favor one side. He is required to be reasonable and just and not preferring any gathering. The judge is required to choose the case before him as per its realities. Much of the time, the arbitrator’s choice is lawfully authoritative thus it is beyond the realm of imagination to expect to go to the court I a gathering is discontent with the choice. There are a wide range of sorts of intervention and most have basic highlights, including-common understanding between the gatherings to mediate; it is private and has less convention than the courts; the choice isn't made by the individual themselves; the procedure is conclusive and lawfully official and there are restricted justification for testing a choice. Assertion is generally utilized for worldwide debates, questions between significant co-enterprises, work rights questions and customer questions. It is represented by the Arbitration Act (AA) 1996 which sets out its principles and gives a definition. The gatherings can for the most part pick an authority, giving they can concur on one. The AA 1996 sets down severe guidelines for how discretion should function. Be that as it may, as mediation is planned to be less formal, more affordable and more adaptable than the court, the principles of proof are not as severe and gatherings can generally have a state by they way they need the meeting to be directed. When the gatherings have chosen to utilize assertion and the procedure has started, the gatherings for the most part surrender their entitlement to look for goals of the issue somewhere else, for example, a court or council. A second alterative premise on which gatherings can resolve questions is by utilizing the procedure of intercession. Intercession is the procedure whereby an outsider goes about as a channel through which two questioning gatherings convey and haggle trying to arrive at a typical goals of an issue. The go between may move between the gatherings, conveying their feelings, without them meeting, or on the other hand, the go between may work within the sight of the gatherings, however in either circumstance, the accentuation is on the gatherings themselves working out a common understanding concerning how the debate being referred to will be to be settled. Intervention is in excess of a unimportant arrangement. A wide range of intercession have the accompanying normal highlights : it is deliberate gatherings can decide to go between or to; it is private and classified, the arbiter is fair and autonomous and the gatherings can choose how it is to be chosen. Intercession can be utilized in cases including just two (2) parties and those including countless gatherings or whole networks. Intervention is the most wide-going ADR process and is utilized in numerous zone of question including, bury alia, business, customer, separation and partition, carelessness, training and individual injury. Most intercession gatherings are finished up inside a day, yet it is workable for intervention to occur more than a few gatherings. There are no set results. The scope of cures than can be accomplished is as wide as you need it to be. You are not limited to the results which a court could arrange. A gathering could settle on an understanding which incorporates a conciliatory sentiment, a guarantee to do or not to accomplish something, compensatory discounts, substitution of merchandise, etc. Intercession is a non-restricting procedure understandings are not lawfully gorging. Be that as it may, it has a decent reputation with regards to keeping understandings. In the event that no understanding is reached, elective strategies can be utilized or gatherings can have plan of action to the courts. Mollification makes intervention a stride further and enables the conciliator to recommend justification for bargain and the conceivable reason for decisive understanding. In this manner, pacification has a more interventionist job. The conciliator ought to be unprejudiced. Mollification is private and the terms of settlement are not made open except if the gatherings concur. The kind of results accomplished are like those in intercession, including-a conciliatory sentiment; clarification and remuneration changes practically speaking or method. Another Mechanism of ADR is the workplace of the Ombudsmen. Ombudsmen are autonomous office holders who research and rule on grievances from individuals from people in general about mal organization in government, and I specific, administrations both the general population and private segment. Some Ombudsmen use intercession as a piece of their question goals methodology. The forces of the ombudsman change. They can make proposal; just a couple can settle on choices which are enforceable. Medications Arb is a mix of intervention and discretion where the gatherings consent to intercede; bit if that neglects to accomplish a settlement, the debate id alluded to mediation. A similar individual may go about as the middle person and the authority in this sort of course of action. In spite of the fact that, not in itself a type of ADR, it is considered important to give a short examination of councils. Councils are fundamentally the same as a court but instead, it is a legal foundation in the way of a court to hear specific complaints or master matters of debate. Instances of courts incorporate the authoritative council, work and modern court. Councils don't regulate any piece of the legal intensity of the state. (Lawyer General v British Broadcasting Corporation [1980]. HL) it has a particular purview as dispensed by designated by Parliament. The qualities and shortcomings of Alternative Dispute Resolution will presently be encouraged trailed by a general review of whether the procedure in itself is effective. For some, reasons, promoters of ADR accept that it is better than claims and prosecution. ADR is commonly quicker. Cases and questions can be settled very quickly or even days, in this manner setting aside less effort to arrive at a choice than trusting that the case will go to preliminary which can take a long time before a choice is reached. It is fundamentally more cost-effective than the conventional courts which at that point to be costly. It depends on more straightforward interest by the disputants, instead of being directed by the courts, legal advisors or even the state. In most ADR forms, the gatherings diagram the procedure they will utilize and characterize the substance of their understandings. This kind of inclusion is accepted to build individuals fulfillment with the results, just as their consistence with the understanding came to. In this way, the gatherings shave a specific measure of adaptability in picking what rule gulp be applied to their contest. An exceptional attribute of ADR is that, not normal for questions in the courts for specific issues, there is no jury included. This is profitable in light of the fact that juries can be eccentric and frequently improve or decline harms granted simply as per whether they favor a specific gathering. Most ADR forms depend on an integrative methodology. They are more helpful and less serious than antagonistic court-based techniques, similar to case. Consequently, ADR will in general produce less acceleration and malevolence between the gatherings. Truth be told, partaking in ADR will frequently eventually improve, instead of exacerbate, the relationship betwe

5 Ways to Stand Out In Any Interview

5 Ways to Stand Out In Any Interview Keep in mind, you’re never the main individual being met for the activity. The recruiting director doesn’t realize how exceptional and gifted you are or what a solid match you’d be except if you show her. What's more, recollect, you’re by all account not the only one attempting to substantiate yourself. Here are 5 hints to ensure you give the best early introduction possible.Dress for the Career You WantMost new interviewees squirm continually, pulling at their evil fitting business-wear. This is quickly diverting and will affect your certainty and the interviewer’s trust in you. Get yourself a decent suit that fits you and your style. In the event that you think you look great, you’ll have the option to unwind and act naturally and center around selling your capacities. Dress for the vocation you need, not really the section level employment you’re applying for!RELATED: 12 HUGE Job Interview Mistakes to AvoidResearch Every Detail Ab out the JobSo numerous new interviewees come in dazzle, hoping to get the hang of all that they have to think about the activity from the recruiting administrator. This doesn't rouse trust in your capacities or activity. Rather, ensure you inquire about everything about you can-about the organization and particularly about the position. That way, you can get ready to talk about how your specific foundation and related knowledge settle on you the most magnificent decision. Who knows, those long stretches of looking after children tending to tables may really be fantastic out-of-the-crate capabilities that will assist you with standing apart from the pack.Impress Hiring Manager with Your Social SkillsDon’t be a creeper, yet it it’s not an ill-conceived notion to check out your interviewer’s office for little signs about their inclinations or diversions. Perhaps they’ve got a confirmation from your institute of matriculation search for anything you an utiliz ation to locate some shared opinion. Simply be certain they’re utilizing their own office and you don’t wind up praising somebody else’s children!Be Smart about the Job You Are Interviewing ForWe’ve all been at the meeting that feels like an espresso date. You yammer on for thirty minutes, yet you barely talk about the activity. This can be an indication of good energy, however it can likewise be a snare. A few questioners may be trying you to see whether you can keep control of the discussion. Attempt (courteously!) guiding things back to your excitement to clarify why precisely you’re the best fit for the position. You’ll be astounded what a small number of your companions are set up to do the same.Prepare, get ready and prepareSo numerous youthful interviewees express in single word or one sentence answers. Set up a couple of model responses to questions you’re prone to be inquired. Don’t transform your answers into a discou rse, yet ensure that with each one, you’re showing your knowledge and sharpness and your reasonableness for the activity. If all else fails, read your interviewer’s non-verbal communication for indications of intrigue or weariness, and modify as needs be.

Laurie Burns Studying Triple-GEM foils

Laurie Burns Studying Triple-GEM foils In 1997, Fabio Sauli invented the Gas Electron Multiplier (GEM) at CERN, the worlds largest particle accelerator. A triple-GEM consists of thin layer of insulating material called Kapton sandwiched between two sheets of copper, making a grand total of three layers (the triple comes from the three separate GEM foils that are stacked to make the final detector.) The composite sheet is then patterned with an array of 600,000 tiny holes (about 70 um in diameter) using a chemical etching process The sheet can be used to detect particles by amplifying ionization patterns by up to ten times. Researchers at the Plasma Science and Fusion Center in the Laboratory for Nuclear Science (LNS) at MIT have developed a prototype detector. Under the guidance of Professor Bernd Surrow and a postdoc, senior Laurie Burns is testing and comparing two types of GEM foils that may be used in future models. GEMs are able to detect particles using well-known physical principles. When a voltage is applied to the foils, a voltage difference appears because the Kapton is an insulator and does not let current pass. This voltage difference creates an electric field, so if a few electrons were to come near the foil, the charge on the surface would be amplified below. It may be easier to think of the GEM as a sort of microscope for charges, where each foil acts as a lens. Once the microscope is hooked up to all the appropriate auxiliary equipment such as an oscilloscope, it can detect, for example, whether a particle is an electron or a positron based on which direction the particle turns in a magnetic field. Most GEMs currently use foils that were created by the CERN Surface Treatment Service. Since CERN is a research facility and not a foil producing business, MITs BatesCenter has begun fabricating its own foils. This is a very delicate process, as a piece of copper stuck in only one of the 600,000 holes can cause the foil to fail. Laurie began her UROP last spring and continued through the summer, where she mostly worked on using scanning software to examine the foils from CERN and Bates. As part of her senior thesis project, she will eventually conduct a comparative study between the two foils by making two model detectors to assess each foils properties such as its gain and lifetime. Once the findings of her study are complete, the LNS hopes to develop a triple-GEM that has a surface area nine times larger than the detector currently in use. Lauries research on triple-GEMs has a lot of fascinating applications. The application that I found most impressive was the ability to detect cosmic rays muons. In general, the GEM is better than other detectors because it is safer to use and produces more gain (ratio of signal output to input). As a physics (course 8) major, Laurie emphasizes that most physics students have the opportunity to conduct experiments in their junior year in the junior lab class. Through the class, students perform eight experiments that provide exposure to various aspects of experimental physics. She says that, in general, physics majors get their first UROPs in their junior year because a lot of background knowledge is necessary to complete meaningful research. Laurie also discussed some research being done by her fellow physics majors. They include studying: Lasers to figure stuff out about gravity (LIGO) Computer processes involving physics at the Lincoln Labs Computer simulations in a joint project with the Stanford Linear Accelerator Center A two-dimensional harmonic oscillator and finding the solutions to it Quantum physics String theory Time travel charge parody (to find out more about this, take Special Relativity (8.20) to find out how to travel into the future!) Astrophysics Lasers (pulsing, optical physics) Originally from Massachusetts, Laurie says that her high school physics teacher is one the reasons she decided to be course 8. In her free time, she likes to play the violin and in the past she was in the MIT Chamber Orchestra. She also likes playing intramural sports like ice hockey and is very involved with her sorority. Laurie is currently in the process of applying to graduate schools in applied physics departments and hopes to research optics in the future. She also has a minor in French and is thinking about putting some of her language skills to use while conducting research at CERN.

Auditory challenged individuals are comprised of nearly 10,000,000 hard-of-hearing and 1,000,000 functionally deaf Americans and a half a million were born or diagnosed deaf before turning eighteen years old in the United States (Mitchell 2006). A great percentage of this demographic primary language is American Sign Language (ASL). These individuals are considered a verbal minority. Within the deaf community â€Å"deaf† is defined as people who have been deaf or hard of hearing entirely or most of their lives.

The Secret Guardian of Gotham Free Essays

The Dark Knight portrays Batman well enough for the audience to easily analyze Batman’s characteristics and personality. Batman is one of the most crucial characters in the movie. Bruce Wayne, or Batman, is portrayed as a billionaire and an owner of a gigantic industry, who actually at night works as a vigilante fighting criminals with his bare hands. We will write a custom essay sample on The Secret Guardian of Gotham or any similar topic only for you Order Now Batman’s sense of morality, self-righteousness, and self-sacrificial attitude in his actions allow effortless classification of Batman’s characteristics in True Color’s Personality Test, Myers-Briggs Personality Test, and Maslow’s Hierarchy of Needs. The way Batman believes the good in people, and the way he spends his nights for the safety of the people in Gotham proves that Batman is most likely the color blue from the True Colors Personality Test. People with blue characteristic hate with fervor, value harmony, give self to others, promotes feelings and warmth among people, and are too generous. Batman falls into all of these descriptions. Even though Batman abhors Joker, he never kills Joker despite all of the chances he is given because he believes in change in human potential, because he wants to inspire others through his actions, and because of his stern self righteousness of always wanting to do what is good for everyone. Also when Harvey Dent died after killing five people â€Å"fairly,† Batman tells Lieutenant Gordon to point the finger at him instead of Harvey Dent. Batman says, â€Å"You will hunt me. You will condemn me. Set the dogs on me, because that is what needs to happen,† (The Dark Knight) in order for people of Gotham to not lose hope by hearing and seeing the downfall of the Gotham’s White Knight, Harvey Dent. This sacrificing attitude is difficult to find in the characteristics of orange, green, and gold, but is the compassionate feature of the color blue. Towards the end of the movie, when Joker sees that the two ships didn’t bomb each other, Batman tells him, â€Å"This city just showed you that it is full of people ready to believe in good,† (The Dark Knight) implying that he, as well, believes in good nature of humans. From what is shown, my hypothesis would be that Bruce Wayne’s dichotomies are ESFJ, or extraverted, sensing, feeling, and judging. Even though Bruce Wayne is surreptitiously living another life as Batman, with only a few close confidants being aware of it, he seems to enjoy social gatherings and occasional dates with many different women. He approaches his criminals through high tech researches and careful observations of facts and proofs. Batman also does not use his sudden insights to act and rather weighs the different possibilities using his tangible sources. Therefore, I assume that Batman is more sensing than intuitive. Bruce Wayne is more feeling in the way he processes data because he considers the points of view of other people and he tries to do whatever establishes harmony within the society. For example, when Bruce Wayne had turned every cell phone in the city into a microphone and a high-frequency generator receiver, knowing that Lucius would not like such dangerous machine, he made it accessible and destructible by only Lucius. Also knowing that citizens of Gotham will lose hope and faith if they learn the truth behind Harvey Dent’s fall and death, Batman says, â€Å"Sometimes the truth is not good enough. Sometimes people deserve more. Sometimes people deserve to have their faith rewarded. † (The Dark Knight) Batman also shows his willingness to do whatever is needed to help Gotham by saying, â€Å"I am whatever Gotham needs me to be. † (The Dark Knight) Maybe because Batman is so engrossed in many different endless jobs he has to finish, he never seems to be having his pleasure and leisure time. He always seems to be task oriented and organized in his plans and well in control with the help of Alfred Pennyworth and Lucius Fox so that the plans never fail. Watching this movie, I could not help but notice the parallel between Jesus from the Bible and Batman. Just like the historical character Jesus, who supposedly had no sin and dedicated to give up his own life for the forgiveness of others, and who eventually gets accused by the same people who used to acclaim him as the â€Å"Savior,† Batman, who did nothing against the morals, gets chased by those who used to praise him as the â€Å"Hero,† by becoming the scapegoat. Therefore, in Maslow’s Hierarchy of Needs, even though I believe that Batman is sometimes on the level of safe and security because he gets injured often while fighting against criminals and Joker, Batman is primarily on the level of self-actualization. He truly dedicates himself for the benefit of others and to satisfy what the citizens of Gotham want. He knows what he is meant to do and does what he does not as a service for himself but as a guidance for the citizens of Gotham. Lieutenant Gordon, watching Batman run away, tells his son, â€Å"Because he is the hero Gotham deserves, but not the one it needs right now, so we will hunt him because he can take it. He is not our hero; he’s a silent guardian, a watchful protector, a dark knight. † (The Dark Knight) Bruce Wayne, Batman, or the Dark Knight’s characteristics summed together support Batman’s famous quote, â€Å"Batman has no limits. † (The Dark Knight) The way he dives into danger every day, cleans up all the violent and illegal mess made in Gotham, and sacrifices himself for people’s mental comfort proves his idealistic characteristics. Because he has no limit, I believe he was able to be the person and the hero portrayed in the movie. Without Batman, his perfect sense of morality, and his boldly courageous deeds, Gotham would not be the same. How to cite The Secret Guardian of Gotham, Essay examples

Developmental Defects of Teeth Essay Example

Developmental Defects of Teeth Paper developmental defects of teeth with recent genetic concepts INTRODUCTION: Disorders of development of teeth may be prenatal or postnatal in origin and may be inherited or acquired. Their recognition and evaluation requires a thorough knowledge and evaluation of the normal chronology of the human dentition and of the normal development and structure of the teeth. Disorders of development of teeth of teeth may be due to abnormalities in the differentiation of the dental lamina and the tooth germs, causing anomalies in the number, size and form of teeth (abnormalities of morphodifferentiation) or to abnormalities in the formation of the dental hard tissues resulting in disturbances in tooth structure (abnormalities of histodifferentiation). Abnormalities of histodifferentiation occur at a later stage in development than abnormalities of morphodifferentiation; in some disorders both stages are abnormal. Histophysiology of tooth development: A number of physiologic growth processes participate in the progressive development of the teeth. These are – 1. Initiation The dental lamina and associated tooth buds represent those parts of the oral epithelium that have the potential for tooth development. Different teeth are initiated at different times. Initiation induction requires ectomesenchymal epithelial interaction. A lack of initiation results in the absence of either a single or multiple teeth or complete lack of teeth. Abnormal initiation may result in the development of single or multiple supernumerary teeth. 2. Proliferation We will write a custom essay sample on Developmental Defects of Teeth specifically for you for only $16.38 $13.9/page Order now We will write a custom essay sample on Developmental Defects of Teeth specifically for you FOR ONLY $16.38 $13.9/page Hire Writer We will write a custom essay sample on Developmental Defects of Teeth specifically for you FOR ONLY $16.38 $13.9/page Hire Writer Enhanced proliferative activity after initiation results successively in the bud, cap and bell stages of the odontogenic organ. Proliferative growth causes regular changes in the size and proportions of the growing tooth germ. A disturbance has entirely different effects according to the time of occurrence and the stage of development that it affects. Tooth anomalies may include disturbances in the size, proportion or number of teeth 3. Histodifferentiation It succeeds the proliferative stage. The formative cells of the tooth germ developing during the proliferative stage undergo definite morphologic as well as functional assignment. Differentiation of odontoblasts and ameloblasts takes place resulting the formation and apposition of enamel and dentin. Disturbance is the stage results in defects in the structure of tooth like amelogensis imperfecta type 1 and 4. 4. Morphodifferentiation The morphologic pattern or basic form and relative size of the future tooth are established by morphodifferentiation that is by differential growth. Dentinoenamel junction and dentinocemental junctions are established. Disturbances in morphodifferentiation may affect the form and size of the tooth without impairing the function of the ameloblasts or odontoblasts. 5. Appposition It is the deposition of the matrix of the hard dental structures. Defects in apposition results in anomalies like amelogenesis imperfecta type 2, dentin dysplasia. 6. Mineralization and Maturation After matrix formation full mineralization and dental hard tissue maturation. Anomalies like amelogensis imperfecta type 3, fluorosis and interglobular dentin. CLASSIFICATION OF DEVELOPMENTAL DEFECTS OF TEETH 1. Anomalies of initiation and proliferation anomalies of number hypodontia and anodontia hyperdontia anomalies of size Microdontia Macrodontia anomalies of shape Germination Fusion Concrescence 2. Anomalies of morphodifferentiation anomalies of size and shape Dilacerations Dens invaginatus Dens evaginatus Taurodontism Talon cusp 3. Anomalies of histodifferentiation enamel defect Amelogensis imperfecta type I dentin defect Dentinogensis impefecta type I,II,III 4.

Anomalies of mineralization enamel defects Amelogenesis imperfecta type III Enamel fluorosis Anomalies of initiation and proliferation Development disturbances in number a. ypodontia and anodontia True anodontia or congential absence of teeth may be of two types Total anodontia – in which all teeth are missing. It may involve both deciduous and permanent teeth. It is a rare condition when it occurs it is frequently associated with generalized disturbances, hereditary ectodermal dysplasia. Partial anodontia (hypodontia or oligodontia) Hypodontia when there is lack of development of one or more teeth Oligodontia is a subdivision of hypodontia indicating the lack of development of six or more teeth. An incidence of 1. 5 – 10% is seen excluding 3rd molars in permanent dentition and . 09 . % for primary dentition. Most frequently affected teeth are 3rd molars, mandibular 2nd premolar, maxillary lateral incisor and maxillary 2nd premolar. In case of deciduous dentition usually maxillary lateral incisor are missing. According to Grahen and Granath there is a close correlation between congenitally missing deciduous teeth and their permanent successors suggesting a genetic factor. A familial tendency for this defect is noted. Graber reported enough evidence that it is actually the result of one or more point mutations most often transmitted in an autosomal dominant pattern with incomplete penetrance and variable expressivity. Some investigators implied that hypodontia is a normal variant suggesting that humans are in an intermediate stage of dentitional evolution. A proposed future dentition would include one incisor, one canine, one premolar and two molars per quadrant. Hypodontia correlates with the absence of appropriate dental lamina. Mostly this is due to genetic alteration. However, environmental factors like trauma, infection, radiation and endocrine disturbance may also result in loss of developing tooth bud. Hypodontia is associated positively with microdontia, reduced alveolar development, increase free way space and retained primary teeth. Pax 9 gene maps to chromosome 14, it encodes a transcription function that is important in the development of pharyngeal pouches. Its mutation may lead to congenitally missing teeth. Syndromes associated with hypodontia: cleft lip/palate crouzon syndrome down syndrome hyphidrotic ectodermal dysplasia ellis van crevald syndrome oro facial digital syndrome b. hyperdontia it is the development of an increase number of teeth. Genetics of hyperdontia suggests an autosomal dominant pattern of inheritance with incomplete penetrance. The variable expression and penetrance of the gene may be affected by the environmental factors. The development of hyperdontia is development of excess dental lamina which leads to formation of additional teeth. An incidence of . 3-3% and a male to female ratio of 2:1 is noted. It occurs most frequently in permanent dentition and approximately 90% of cases present in maxilla with a strong predilection for the anterior region. Terms used to describe supernumerary tooth depending on their location i. Mesiodens is located in the maxillary incisor resion. It is the most common supernumerary. ii. Distodens/ distomloar is the accessory fourth molar iii. Paramolar is a posterior supernumerary tooth situated lingually or buccally to a molar tooth. Classification based on morphology In the primary dentition morphology is usually normal or conical. Greater variety is seen in case of permanent dentition Conical is a small peg shaped conical tooth and is the most common supernumerary. It develops with root formation ahead or at an equivalent stage to that of permanent incisor. It can result in rotation or displacement of the permanent incisor but rarely delays eruption. Tuberculate possess more than one cusp or tubercle and is barrel shaped. Root formation is delayed as compared to permanent incisors. They are often paired and are commonly located on the palatal aspect of the central incisors. It results in delayed eruption of the incisors. Supplemental refers to a duplication of teeth on the normal series and is usually found at the end of the tooth series. Most commonly permanent maxillary lateral incisor is the supplemental supernumerary. Majority of the deciduous supernumeraries are of this type. Odontome is listed as the fourth category by Howard. It is a hamartomoatous malformation nd is composed of more than one type of tissue called composite odontoma. Mainly two types are there complex and compound. Syndromes associated with hyperdontia 1. cleft lip/palate 2. cleidocranial dysplasia 3. gardner syndrome 4. oro facial digital syndrome Developmental disturbances in size of tooth a. microdontia – teeth which are smaller than normal. Females demonstrates a higher a frequency of microdontia and hypodontia. Thre e types are True generalized microdontia in this all the teeth are smaller than normal. It is seen in cases of piutatry dwarfism, Down syndrome, congenital heart diseases. Relative generalized microdontia normal slightly smaller teeth present in the jaws larger than normal producing an illusion of microdontia. Role of hereditary as jaws are inherited from one aren’t and tooth size from other parent. Microdontia involving single tooth is common condition affects maxillary lateral incisors and 3rd molar most commonly. b. macrodontia – teeth that are larger than normal. Three types similar to that microdontia True generalized macrodontia all teeth are large. Seen in cases of pituitary gigantism and pineal hyperplasia with hyperinulinism. Relative generalized macrodontia presence of normal teeth in similar jaw giving an illusion of macrodontia Macrodontia of single tooth relatively uncommon. Occasionally seen in cases of hemihypertrophy of the face. Should not be confu sed with fusion of teeth. Development disturbances of shape of teeth a. germination – anomalies which arise from an attempt at division of single tooth germ by an invagination with resultant incomplete or complete formation of teeth. Incidence of . 5% is seen and it more common in primary dentition. Higher frequency in maxillary anterior region. It may retard eruption of permanent successor. Usually appear as one with two completely or incompletely separated crowns that have a single root and root canals. Twining production of equivalent structure by divisions resulting in one normal and one supernumerary tooth. Etiology is unknown although a genetic basis has been suggested. b. fusion – union of two normally separated tooth germs. Depending upon the stage of development of the teeth at the time of the union. More common in the deciduous than in the permanent dentition. Union by dentin, separate pulp chambers/ canals. May retard eruption of permanent successor. . concrescence – form of fusion which occurs after root formation. Teeth are united by cementum only. As a result of traumatic injury or crownding of teeth with resorption of the interdental bone. More frequently in the posterior and maxillary region. Anomalies of morphodiferentiation Anomalies of size and shape a. dilaceration: An angulation or a sharp bend or curve in the root or crown of a formed tooth. Due to trauma during the period in which the tooth is forming, with the result that the position of the calcified portion of the tooth is changed and the remainder of the tooth is formed at an angle. Syndrome associated with dilaceration. Lamellar ichthyosis. Present difficulty at the time of extraction. b. dens invaginatus: dens in dente It is a deep surface invagination of the crown or root that is lined enamel. Results due to invagination in the surface of tooth crown before calcification has occurred. This can be due to increased localized external pressure focal growth retardation and focal growth stimulation in certain areas of the tooth buds. The permanent maxillary lateral incisors are the teeth most frequently involved. Two forms are usually seen as Coronal dens in dente – more frequent prevalence varies from . 4% to 10%. Depth of iinvagination varies from a slight enlargement of the cingulum pit to deep infolding that extends to the apex. Radicular dens in dente – rare and thought to arise secondary to proliferation of hertwig’s root sheath with the formation of a strip of enamel that extends along the surface of the root. Radiographiclaly the affec ted tooth demonstrates an enlargement of the tooth. It chances of caries and pulp infection. c. dens evaginatus – Leong’s premolar it is a developmental condition that appears clinically as an accessory cusp or a globule of enamel on the occlusal surface between the buccal and lingual cusps. Unilaterally or bilaterally with an increased mandibular predominance. Pathogenesis is the proliferation and evagination of an area of the inner enamel epithelium and subjacent odontogenic mesenchyme in to the dental organ during early tooth development. If seen in association with another varaiton of coronal anatomy. Shovel shaped incisors affected incisors demonstrate prominent lateral margins, creating a hollowed lingual surface. Maxillary incisor is the most commonly affected. This extra cusp may contribute to incomplete eruption, displacement of teeth and/or pulp exposure with subsequent infection following occlusal wear or fracture. . taurodontism – it is an enlargement of the body and pulp chamber of multirooted tooth with apical displacement of the pulpal floor and bifurcation of the roots. Overall shape of the taurodont resembles that of the molar teeth of cud chewing animals â€Å"bull like† Shaw classified taurodont teeth into 3 division according to the degr ee of apical displacement of pulpal floor hypotaurodont (mild) mesotaurodont (moderate) hypertaurodont (severe) may occur as an isolated trait or as a component of specific conditions like 1. klinfilter’s syndrome . amelogenesis imperfecta 3. orofacial digital syndrome 4. hypohydrotic ectodermal dysplasia 5. tricho dento osseous syndrome 6. down syndrome It is seen that taurodontism may develop in presence of any one of a large number of different genetic alterations. These findings suggest that chromosomal abnormalities may disrupt the development of the tooth form and that taurodontism is not the result of any specific genetic abnormality e. talon’s cusp – Is also known as dens evginatus of the anterior teeth. It is a well delineated cusp that is located on the surface of an anterior tooth. Predominantly affects permanent dentition esp maxillary lateral incisors. It projects from the lingual surface of the affected tooth and forms a three pronged pattern that resembles an eagle’s talon. The cusp blends smoothly with the tooth except that there is a deep development groove where the cusp blends with the sloping lingual tooth surface. It is associated with other dental abnormalities like supernumearary teeth, odontomas, impacted teeth; peg shaped lateral incisors and dens invaginatus. It is also associated with other syndromes like Rubinstein Tyabi syndrome Sturge Weber syndrome. Complications like interference with occlusion, comprised esthetics, displacement of teeth, caries, periodontal problems and irritation of the adjacent soft tissue may occur. ANOMALIES OF HISTODIFFERENTIATION Enamel defects a. Amelogenesis imperfecta type I AI is a heritable enamel defect in the absence of any systemic disease. Reported incidence varies from 1:14000 to 1:4000. Multiple inheritance patterns are noted. It may differentiated into 4 main groups depending on the clinical presentation and the likely stage of enamel formation that is primarily affectes. hypoplatic hypocalcified hypomature hypomature hypoplastic with taurodontism Each group is further subdivided into several subgroups depending on the mode of inheritance as well as the clinical appearance of the defective enamel. Genetic studies – have shown that etiology of AI is related to the alteration of genes involved in the process of formation and maturation of the enamel. X linked AI has shown the defectiv e gene is closely linked to the locus DXS85 at Xp22. this site has been identified as the general location of the human gene amelogenin the principal protein in the developing enamel. In the case of autosomal dominant type of AI the locus of the defective gene is on the ch 4q21 to which enamel protein enamelin maps. AI type I Hypoplatic The basic alteration centers an inadequate deposition of enamel matrix. Any matrix present is mineralized appropriately. Subgroups (Witkop 1989) I A – hypoplastic, pitted AD I B – hypoplastic, local AD I C – hypoplastic, local AR I D – hypoplastic, smooth AD I E – hypoplastic, smooth XR I F – hypoplastic, rough Ad I G – enamel agenesis, AR Clinical feature: In the generalized pattern pinpoint to pinhead sized pits are scattered across the surface of the teeth. Buccal surfaces of the teeth are affected and staining of these pits may occur In the localized pattern, the affected demonstrate horizontal rows of pits a linear depression. The altered area is located in the middle third of the buccal surface of teeth. The type IC is more severe and typically demonstrate involvement of all teeth in both dentitions In type ID the enamel of all teeth exhibits a smooth surface and is thin hard and glossy Anterior open bite is seen and teeth exhibit a thin peripheral outline of radiopaque enamel on radiograph In type IE this is a lesion showing lionization effect. In females the teeth would exhibit alternating zones of normal and abnormal enamel. Males exhibit diffuse thin, smooth and shiny enamel in both dentitions. The teeth have the shape of crown formation with open contacts. In the rough pattern, the enamel is thin, hard and rough surfaces. An anterior open bite is common. In enamel agenesis demonstrate total lack of enamel. The teeth are the shape and color of the dentin. The surface is rough. Dentin defects b. Dentinogenesis imprfecta A hereditary developmental disturbance of the denitn in the absence of any systemic disorder. This is an autosomal dominant condition affecting both deciduous and permanent teeth. Affected teeth are gray to yellowish brown and are tulip shaped. Genetic studies show that the gene defective maps to chromosome 4 in case of type II. It encodes a protein called dentin sialophosphoprotein and constitutes about 50% of the noncolllagenous component of dentin matrix. DI type I is due to mutational changes in gene coding pro alpha 1, pro alpha 2 chains of type I collagen, major protein of organic matrix in bone and dentin. Recent studies report that type II and type III arise from a single mutation of DSPP gene and that these are not separate disease but rather phenotypic variation of a single disease. Acc. to Sheild’s classification DI type I – osteogenesis imperfecta with opalescent teeth DI type II – isolated opalescent teeth DI type III – isolated opalescent teeth Brandywine Extensive studies have proven that DI is a disorder distinct from Osteogenesis imperfects so a revised classification is proposed DI type I corresponds to type II of Sheild’s Type II corresponds to type III of Sheild’s There is no substitute for type I of Sheild’s classification Clinical and radiographic features deciduous teeth are affected most severely followed by the permanent incisors and first molars enamel is normal but separates easily from dentin because of defective dentinoenamel junction once exposed the dentin often demonstrates significantly accelerated attrition radiographically, the teeth have bulbous crowns cervical constriction thin roots and early obliteration of the root canals and pulp chambers. Type III has shell teeth demonstrating normal thickness enamel in association with extremely thin dentin and dramatically enlarged pulps Histologic features The dentin adjacent to the enamel junction appears similar to normal dentin but the remainder is distinctly abnormal Short tubules course through an atypical granular dentin matrix which often demonstrates interglobular calcificaiton. Cells can be seen entrapped within the defective dentin Anomalies of apposition Enamel defects a. amelogenesis imperfecta type II IV AI type II – hypomaturation the enamel matrix is laid down appropriately and begins to mineralize however there is a defect in the maturation of the enamel crystal structure Classified into Type IIA – hypomaturation, pigmented AR Type IIB – hypomaturation, X linked recessive Type IIC – snow capped teeth, AD Genetic studies show that multiple mutations in the AMELX gene in the type IIA AI whereas IIA C the gene defect is unknown. Clinical features Affected teeth are normal in shape but exhibit a mottled, opaque white brown yellow discoloration. The enamel is softer than normal and tends to chip from the underlying dentin. Radiographically the affected enamel exhibits a radiodensity that is similar to that of dentin. Type IIA the surface enamel is mottles and agar brown. Enamel is soft enough to be punctures by an explorer Type IIB shows lionization that is male exhibit differebti pattern in deciduous and permanent teeth. The deciduous teeth are opaque white with a translucent mottling; the permanent teeth are opaque and may darken with age. Female patients exhibit a similar pattern in both dentitions. The teeth demonstrate vertical bands of white opaque enamel and normal translucent enamel. Radiographically the bands are not perceptible. Type IIC exhibits a zone of white opaque enamel on the incisal or occlusal third of the crown. AI type IV – hypomaturation hypoplastic with taurodontism This type of Ai exhibit enamel hypoplasia in combination with hypomaturation. Classified into Type IV A hypomaturation hypoplastic Type IVB hypoplastic hypomaturation Genetic defects in both groups is unknown Type IV A the predominant defect is one of enamel hypomaturation in ehich the enamel appears mottled yellowish white to yellow brown. Pits are seen frequently on the buccal surface of the teeth. Radiographically the enamel is similar to dentin in density and large pulp chambers may be seen in addition to varying degree of taurodontism Type IVB the predominant defect is one of enamel hypoplasia in which the enamel is thin; the enamel that is present demonstrates hypomaturation. Radiographically there is decrease in the thickness of the enamel. Both these types are seen in the systemic disorders, trich dento osseous syndrome. Other features seen are kinky hair, osteosclerosis and brittle nails. b. enamel pearl Refers to the presence of enamel in unusual locations mainly the tooth root. These are hemispheric structures that may consist entirely of enamel or contain underlying dentin and pulp tissue. These are thought to arise from a localized bulging of the odontoblastic layer. This bulge may provide prolonged contact between Hertwig’s root sheath and the developing dentin, triggering induction of enamel formation. t is found most frequently on the roots of maxillary molars. The enamel pearls precludes normal PDL attachment with CT. Dentin defects c. dentin dysplasia It is a rare disturbance of dentin formation characterized by normal enamel but atypical dentin formation with abnormal pulpal pathology. It is an abnormality that maps to the same site on ch 4 as does DI type II III. It too may be an allelic variant. Cl assified into Type I radicular dentin dysplasia Type II coronal dentin dysplasia Both these patterns appear to be hereditary diseases, transmitted as an autosomal dominant characteristic. Clinical features Type I both dentitions are affected although the teeth are clinically normal. The teeth are extremely mobile and exfoliated prematurely Type II both dentitions are affected. Deciduous teeth have the same color as that in DI but the permanent dentition is normal. Type I both dentitions roots are short blunt and conical. In deciduous pulp chambers and root canals are completely obliterated. Permanent teeth crescent shaped pulpal remanant remains. Periapical radiolucencies involving intact teeth are present. Type II deciduous dentition presents with completely obliterated pulp chambers. Permanent teeth exhibit an abnormal large pulp chamber in the coronal portion. Histologic features Type I a portion of coronal dentin is normal. Most of the pulp is obliterated by calcified tubular dentin, osteodentin and fused denticles. New dentin forms around these obstacles giving the characteristic appearance described as Lava flowing around the boulders. Type II deciduous tee th exhibit amorphous and atubular dentin in the radicular portion while coronal dentin is normal. Permanent teeth same but the pulp has multiple pulp stones. d. regional odontodysplasia It is a localized non hereditary development abnormality of teeth with extensive adverse effects on the formation of enamel, dentin and pulp. Proposed causes abnormal migration of neural crest cells latent virus local circulatory deficiency local trauma or infection hyperpyrexia malnutrition radiation therapy somatic mutation pathosis associated with RO ectodermal dysplasia epidermal nevi hypophosphatasia hydrocephalus neurofibromatosis Rh incompatibility Vascular nevi Clinical features maxillary teeth esp anterior are most commonly affected female predilection with a ratio of 1. 4:1 the affected teeth fail to erupt and their shape is markedly altered the erupted teeth show small irregular crown that is yellow to brown with rough surface on x ray they have a very thin enamel and dentin surrounding an enlarged radiolucent pulp There is lack of contrast between enamel and dentin. Histologic features marked reduction in the amount of dentin and widening of predentin layer presence of large areas of interglobular dentin and an irregular pattern if dentin the reduced enamel epithelium around nonerupted teeth show many irregular calcified bodies known as enameloid conglomerates (also seen in AI) e. hypercementosis It is a nonneoplastic deposition of excessive cementum that is continous with normal radicular cementum Clinical and radiographic features in x ray affected teeth demonstrate a thickening or blunting od the root the enlarged root is surrounded by the radiolucent PDL space and intact dental lamina may be isolated or involve many teeth premolars are involved more frequently predominantly in adults and the frequency increases with age factors associated with hypercemntosis i. local 1. abnormal occlusal trauma 2. adjacent inflammation 3. unopposed teeth ii. systemic 1. acromegaly 2. arthritis 3. alcinosis 4. paget’s disease 5. rheumatic fever Histologic features periphery of root exhibits deposition of an excessive amount of cementum this may be hypocellular or ostecementum the material is arranged in concentric layers Anomalies of mineralization a. amelogenesis imperfecta type III hypocalcifeid in this type the enamel matrix is laid down appropriately but no significant mineralization occurs. Classified into Type III A – autosomal dominant Type IIIB – autosomal recessive In both gene defect is unknown. Most common type of AI. Teeth are norma on eruption but the enamel is very soft and easily lost. Enamel is yellow brown on eruption and turns to brown black due to staining. Autosomal recessive are more severe than the dominant type. Radiographically the density is similar for both enamel and dentin. CONCLUSION An understanding of the many disturbances of development of teeth is predicated upon s thorough understanding of the embryology of these structures. Genetic factors are undoubtedly of importance in the development of these defects. REFERENCE: ? Oral pathology by Shafer ? Oral pathology by Somes and Southam ?

Gone in 60 Seconds essays

Gone in 60 Seconds essays Gone in 60 Seconds reunites actor Nicolas Cage with producer Jerry Bruckheimer. The two are known for some of the best action movies ever, including The Rock and Con Air. Gone in 60 Seconds carries on that very same tradition with fast high speed action and fast high speed car chases. Gone in 60 Seconds tells the story of Randall Memphis Raines (Cage), a retired car thief who has given up the life of crime and has settled down. His younger brother (Ribisi), is still very much into the car stealing scene, and has gotten himself into trouble with his boss by botching a high priced boost. The boss then sends an ultimatum to Memphis: either he comes back to the business and lifts 50 cars in 4 days, or his brother dies. Memphis decides to return to his former profession for the sake of his brother, and gathers some old friends and forms a crew of car boosting experts. The chemistry between most of the characters works. Cage plays the protective older brother to Ribisi, a kid whos gotten into the life too deep and finds himself in more trouble than he can handle. Robert Duvall is the veteran who masterminds the whole The supporting cast is there for some comic relief. They fill the movie with many cliches and stereotypes. Ribisis young friends are the exact opposite of Cages crew. They are using their new high tech gadgets to steal cars for the money, unlike Cage and his crew who do it for the rush. In one of the funnier scenes, a member of Cages team is car-jacked while he is driving away with a stolen car. Instead of surrendering, he curses, gets out of his car, beats down the car-jacker, and lectures him that hes an amateur who doesnt know the first thing about reall ...

Mixture Definition and Examples in Science

Mixture Definition and Examples in Science In chemistry, a mixture forms when  two or more substances are combined such that each substance retains its own chemical identity. Chemical bonds between the components are neither broken nor formed. Note that even though the chemical properties of the components havent changed, a mixture may exhibit new physical properties, like boiling point and melting point. For example, mixing together water and alcohol produces a mixture that has a higher boiling point and lower melting point than alcohol (lower boiling point and higher boiling point than water). Key Takeaways: Mixtures A mixture is defined as the result of combining two or more substances, such that each maintains its chemical identity. In other words, a chemical reaction does not occur between components of a mixture.Examples include combinations of salt and sand, sugar and water, and blood.Mixtures are classified based on how uniform they are and on the particle size of components relative to each other.Homogeneous mixtures have a uniform composition and phase throughout their volume, while heterogeneous mixtures do not appear uniform and may consist of different phases (e.g., liquid and gas).Examples of types of mixtures defined by particle size include colloids, solutions, and suspensions. Examples of Mixtures Flour and sugar may be combined to form a mixture.Sugar and water form a mixture.Marbles and salt may be combined to form a mixture.Smoke is a mixture of solid particles and gases. Types of Mixtures Two broad categories of mixtures are heterogeneous and homogeneous mixtures. Heterogeneous mixtures are not uniform throughout the composition (e.g. gravel), while homogeneous mixtures have the same phase and composition, no matter where you sample them (e.g., air). The distinction between heterogeneous and homogeneous mixtures is a matter of magnification or scale. For example, even air can appear to be heterogeneous if your sample only contains a few molecules, while a bag of mixed vegetables may appear homogeneous if your sample is an entire truckload full of them. Also note, even if a sample consists of a single element, it may form a heterogeneous mixture. One example would be a mixture of pencil lead and diamonds (both carbon). Another example could be a mixture of gold powder and nuggets. Besides being classified as heterogeneous or homogeneous, mixtures may also be described according to the particle size of the components: Solution: A chemical solution contains very small particle sizes (less than 1 nanometer in diameter). A solution is physically stable and the components cannot be separated by decanting or centrifuging the sample. Examples of solutions include air (gas), dissolved oxygen in water (liquid), and mercury in gold amalgam (solid), opal (solid), and gelatin (solid). Colloid: A colloidal solution appears homogeneous to the naked eye, but particles are apparent under microscope magnification. Particle sizes range from 1 nanometer to 1 micrometer. Like solutions, colloids are physically stable. They exhibit the Tyndall effect. Colloid components cant be separated using decantation, but may be isolated by centrifugation. Examples of colloids include hair spray (gas), smoke (gas), whipped cream (liquid foam), blood (liquid),   Suspension: Particles in a suspension are often large enough that the mixture appears heterogeneous. Stabilizing agents are required to keep the particles from separating. Like colloids, suspensions exhibit the Tyndall effect. Suspensions may be separated using either decantation or centrifugation. Examples of suspensions include dust in air (solid in gas), vinaigrette (liquid in liquid), mud (solid in liquid), sand (solids blended together), and granite (blended solids). Examples That Are Not Mixtures Just because you mix two chemicals together, dont expect youll always get a mixture! If a chemical reaction occurs, the identity of a reactant changes. This is not a mixture. Combining vinegar and baking soda results in a reaction to produce carbon dioxide and water. So, you dont have a mixture. Combining an acid and a base also does not produce a mixture. Sources De Paula, Julio; Atkins, P. W.  Atkins Physical Chemistry  (7th ed.).Petrucci R. H., Harwood W. S., Herring F. G.

Plate Tectonics Research Paper Example | Topics and Well Written Essays - 1250 words

Plate Tectonics - Research Paper Example is composed of plates that are in motion with respect to one another and that the majority of the deformation associated with this motion is concentrated along the plate boundaries (Fichter, 2000). Back in 1968, Morgain provided an explanation that plate tectonics constitutes "a kinematic model which describes the relative motion between the rigid plates that make up the outer shell of Earth" (Morgan, 73). Practically, the relative motion between the plates is accommodated by seafloor spreading and the creation of new plates at ocean ridges, subduction of the surface plate at ocean trenches, and strike-slip motion at transform faults which allows plate motion without creating or removing surface plates. The motion of the continents is facilitated by the movement of the lithospheric plates, and this transport of the continents is referred to as continental drift. Plate tectonics on Earth has been determined to have been in operation for at least two billion years and may well have bee n in operation much earlier (Cawood et al., 5). theory, with its collisional orogenies and other episodic events, was in some wise dependent or interdependent upon "new catastrophism." That is, though plate tectonics largely relies upon uniformitarianism as a basis of understanding plate motion and subsurface processes, it nevertheless proffers catastrophes and other episodic events that proceed at rates greater than those existing between events. Examples include mountain building, various volcanic processes, and sea-level change resulting from mid-oceanic ridge formation. Between 1908 and 1912, Frank B. Taylor, American geologist, and Alfred Wegener, a German meteorologist and astronomer, working independently, proposed the idea that the continents were not fixed on the surface of the Earth but were slowly moving about. One point of Taylor's argument was that continental drift was needed to account for the folding and compression of the Alps and the Himalayas. Wegener was more influenced by the rough parallelism between the opp osing shores of the Atlantic and by evidence of climatic changes through geological time. Later Wegener proposed that all the Earth's land area was at one time "united in a single primordial supercontinent, which he named Pangaea, from Greek meaning 'all land" (Hallam, 93). The continents had shifted, becoming increasingly separated through millions of years. He believed that the continent were made up of light-weight granitic rocks, which like giant ships driven through the heavier basaltic seas (Hallam, 95). Wegener looked upon the continents as flexible masses instead of rigid plates. Some of his work was in error, for example, the amount of time involved in continental drift. Alfred Wegener established a tradition in geology and geophysics, according to which further development of theory of plate tectonics has been formed within the scientific debate over the ideas of stationary continents and continental drift. For instance, Hallam commented that "interpretation of how science

EMR Implementation and Patient Flow Case Study Example | Topics and Well Written Essays - 500 words

EMR Implementation and Patient Flow - Case Study Example Another benefit of the EHR is that all medical information can be created and supervised by authorized users. That`s option allowed providers to share the health information with the other health care providers to improve the quality and productivity of the diagnostic and treatment processes. But, the implementation process of the EHRs is not that quickly, easily and cheap because it requires some period of time for health providers education and adaptation of the health care system to the new model of the patient`s health information. The most difficult environment for the EHRs implementation is an emergence department as there are a lot of barriers such as crowding, limited staffing and increased amount of interruptions. The main question is: â€Å"Whether the overflow clinic model could be quickly adapted to offload the emergency department for the implementation of the EHR?† The other important information that have to be quantitatively confirmed is the effects of the EHR implementation on time to medical provider, total patient`s length of stay (LOS), provider efficiency during and after the implementation of the EHR. In addition, the quiet necessary question is: â€Å"How much time and training required for implementation and adoption of the software?† The data were gathered from the Cincinnati Children’s Hospital Medical Center emergence department during the 2 years of the EHR implementation. During this period the H1N1 flu pandemic occurred that lead to increased number of the patients. The results showed that the total length of stay during EHR implementation increased compared to the overall LOS before implementation. It takes 6 months post- implementation to gain improved and stable LOS. I suggest that received results show that the process of the EHR is quite slow because of the different reasons and barriers existed in the emergence departments. For example, health care providers require more time to learn how to use EHR as they have busy

Interpretation And Appreciation Of The Floral Motif Arts Essay

Interpretation And Appreciation Of The Floral Motif Arts Essay Since this is a historical based paper focusing on the way in which wallpaper designers communicate through the use of visual language, different interpretations of the subject of botanical forms, historical background information must be provided to make a fuller understanding possible. This chapter is vital to the study of two dimensional surface design as it will explore the history of wallpaper and the reason one desires to decorate ones surroundings. 2.2. Literature review As well as the research carried out exploring the innovations of 20th century wallpaper design and the exploration of different interpretations of the floral motif, some considerable time was also dedicated to investigate the early history of wallpaper. The basic intention of undertaking this research was to examine the way in which wallpaper appeals to society and to provide a more in depth understanding of the sophistication of wallpaper design, which is a vital element of this study. Questions that are deriving the construction of the historical chapter include: Where did the concept of wallpaper originate from? What was the function of wallpaper? When were flowers and botanical forms first used as a form of decoration? The above objectives were explored by the study of literature surrounding the topic of the history of wallpaper, combing knowledge from books, journals, interior design magazines, and the information from internet sources. The final dissertation will answer these questions and draw relevant conclusions concerning the innovations of two dimensional surface design. The literature review in this section is intended to name the sources used and does not attempt to evaluate the categorised research which underlies them. For this historical chapter a number of sources have been thoroughly researched however some of the sources were more informative than others. Wall Papers of France 1800-1850 by Odile Nouvel (1981) gives a comprehensive narration of the history of wallpaper dating back to wallpapers before the nineteenth century and also refers to British wallpaper design. A similar book in terms historical background information which was also studied, Wallpaper in America From The Seventeenth Century to World War 1 by Catherine Lynn(1980) concentrates more on the styles of wallpaper and refers to British and French influences on American Wallpaper design. Chapter three Eighteenth-Century English wallpaper styles devotes 36 pages of typical wallpaper styles, motifs and patterns from this century including an in depth section on floral patterns. Whether printed in distemper or varnish colours, or whether flocked, floral motifs derived from textile prototypes form the largest category of repeating pa tterns in this relatively large group of wallpapers known to have been used. (Catherine Lynn 1980 p52) this chapter will be more relevant to later sections of this paper due to the specific information on the interpretation of the floral motif and also the detailed annotations of the provided images which clearly demonstrate the style as well as the predominant characteristics of wallpaper from the 18th century. The Floral home Introduction by Leslie Geddes-Brown (1992) is a very good informative source referring to the history of the floral motif which was a more difficult subject to track down using internet sources. More up to date sources which were looked at closely include Lesley Jacksons Twentieth Century Pattern Design and Off The Wall by Lena Lencek and Gideon Bosker which both examine pattern as a quintessential part of the 20th Century design history. Both authors provide a brief, informative history of wall coverings since the 15th century and suggest that wallpaper often reflects the cultural climate of the era of which it was produced. Timothy Brittain-Catlins A Papered History states that wallpaper was for, who chooses it, who pays for it, who it applies to and who appreciates it are all questions that have had different answers at different times. (A Papered History p7) The three books mentioned above will be very useful in terms of putting into context how wallpaper designers, historic and contemporary, are influenced by their social surroundings which in result affect the aesthetic qualities of their designs. The most valuable source however has been the wallpaper history website which lists and allows access to online articles which provide a very detailed insight to the history of wallpaper. The most relevant articles relating to this chapter have been by Alan Benjamin (2009) and Babara Krasner Khait (2001) where both texts are designed as an aid in comprehending the many facets of todays products. Benjamin in particular refers to evidence of wall coverings which dates back to thousands of years B.C, with the use of cave drawings and although this does not resemble wallpaper as we know it today it does signify mans earliest desire to decorate ones surroundings. The history of wallpaper chapter in his article provides a very specific and technical overview referring to the development of wallpaper and how it was used functionally as well as aesthetic purposes in the 16th century to keep out the cold and damp. Both articles are very well written, being short yet adequate and objective his torical accounts which are essential for this paper. Where did the concept of wall coverings originate from? According to archaeologists, the tradition of decorating walls dates back to several thousand years B.C in the form of cave drawings and still to this day it is uncertain as why ancient ancestors chose to decorate their surroundings. The two major theories concerning the reasons behind these graphics are explained as wish fulfilment and aesthetics of art. Although this does not resemble wallpaper as known today, it does signify mans earliest desire to decorate his surroundings. (Benjamin 2009) The ancient Egyptian and Roman civilization are also noted in history to have painted their living environment in a highly individual manner expressing two dimensional portrayals of visible and invisible worlds Earth and the domain of the Gods. (Benjamin 2009) Wallpaper actually begun in ancient China, first because the Chinese invented paper, and secondly because they glued rice paper onto their walls as early as 200 B.C What is the function of wallpaper? The use of wallpaper initially began as a cheap substitute for tapestry and panelling. Some historians believe that the use of wallpaper dates back to the 1400s. (Krasner-Khait 2001) The first wallpapers in England were individual sheets, decorated with geometrical woodcut patterns and printed in black ink on pale paper by a hand operated press. These papers could have been used for anything from covering up an unfortunate space, concealing uneven plasterwork or as an innovative alternative to hanging pictures on the wall. (Brittain-Catlin p7) Homes were built of stone during this period so the main function and practicality of these hangings was used to keep out the cold and damp. Wallpaper was soon to become the poor mans tapestry, an imitation of the expensive textiles used in royal households. Elizabethan England saw a higher demand for wallpaper as its popularity increased. The elite of society were accustomed to hanging large tapestries on the walls of their homes, a tradition from the middle ages. (Wikipedia, the free encyclopaedia) These tapestries added colour as well as providing an insulating layer between the stone walls and the room, thus retaining heat in the room. However, tapestries were very expensive and therefore only the very rich could afford them. For the not so rich members of the elite, they turned to wallpaper to brighten up their rooms as they were unable to but tapestries due to price or wars preventing international trade. Throughout Europe, a fascination began with these papers that offered protection against dampness and improved ability to handle fireplace smoke. In the twentieth century, when mass production, innovated materials, and printing techniques cross pollinated with an unprecedented fluidity of traditions and designs, wallpaper leapt from its privileged position as a covering for the elite to become the truly democratized and democratizing purveyor of domestic elegance refinement and in some cases, downright kitsch. (Lencek and Bosker, 2004, p9) When were flowers first used as a form of decoration? It is extraordinary how floral art crops up in every century and civilization. There is evidence of a detailed wall painting from ancient Egypt that depicts geese grazing from grasses and tiny red flowers which dates back from 2550B.C. Indeed if a tribe or nation does not respect and recreate the beauties of nature, it has little claim to be called civilized. (Geddes-Brown 1992 p8) The flower was used as a symbol and sometimes reflected religious beliefs. The Iris and Lily were both symbols of royalty and the Virgin Mary and were popular subjects of renaissance painters. It is a mistake to identify floral art and decoration only with the chintzy, the countrified and the cosy though all these styles have tremendous charm. Flowers can be architectural (the Greeks used palm and acanthus leaves for their capital), political (roses and thistles were secret Jacobite signs) and perhaps even sinister (the blood thirsty cultivated dahlias and zinnias). (Geddes-Brown 1991 p8) SUMMARY!!!! 3 Victorian wallpapers Introduction Being noted as important era in the history of wallpaper design, a considerable amount of time was dedicated thoroughly researching Victorian wallpaper. This is an important chapter in the study of the floral motif as this period not only put British design on the map but also redesigned wallpaper all over the world and is still, to this day, popular within the interior market. As well as the typical characteristics of Victorian wallpaper, much attention will be given to the research of British designer William Morris, who not only was a one- man pattern-making phenomenon, but was also the founding father of the arts and crafts movement. The overall aims and objectives of this chapter will draw conclusions as to why this period of design was so revolutionary and why Morriss designs are still used to influence todays designers. It will put into perspective how wallpaper has developed with the ever changing society and how the subject of the floral motif has morphed from a realistic representation to a more abstract and simplistic form throughout the centuries. Literature review The Victorian era, was a grand time for wallpaper featuring over embellished designs. Floral Prints were very popular in Victorian England. Print upon print lined the interior walls of rooms, mostly in a rich and heavy colour palette. Dark red, bottle green, chocolate brown, maroon and deep glowing blue were predominant in a great profusion of pattern and ornament. The advent of mass production of wallpaper put the cabbage rose and arabesque patterns within the budget range of practicality of every home. Designers such as William Morris and his lyrical interpretations of nature, hand-printed by the wood block method, came to symbolize Art Nouveau. William Morriss first wallpaper designs started to appear in the 1860s. They came as a slightly later edition to the textile designs. Morris himself was not a big fan of wallpaper for interiors. He much preferred the idea of using hung textile work, such as tapestry or heavy fabrics framed as panels, which he saw as more traditional for interiors than the fairly recent wallpaper industry. Another reason was the difficulty in achieving a good and faithful reproduction of initial design work. Morris was a definite perfectionist and was not prepared to take on a medium if the results were to be less than perfect. William Morris maintained that beautiful surroundings improve the quality of life, and that all of the elements which play a part in the overall style of an interior, textiles and wall coverings are among the most important. Whatever you have in your room, think first of your walls, for they are that which makes your house a home William Morris (1834-1896). William Morris Floral wallpaper designs. Naturalistic flowers and fruit were characteristics of early Victorian wallpapers; initially, they were superimposed on classical architectural backgrounds but in the 1840s they were intertwined with elaborate scrolls and cartouches. By the 1850s, however, design innovators such as Owen Jones and AWN Pugin had rejected this naturalism in favour of flat, formalised patterns. John Ruskin whose theories on design had a big effect during the second half of the nineteenth century, rejected the whole repertory of Renaissance-Classical decorative motifs as prefabricated. William Morris, the guiding light of the arts and crafts movement of the 1870s and 1880s generally shared the views of Pugin, Jones and Ruskin. He believed however that flowers used in textiles and wallpaper designs should be seen to be growing naturally. Motifs from nature, though flattened and stylised, were clearly outlined and recognisable in is patterns. They retained their fundamental characteristics, yet their style was so emphasised. Morris and other Arts and Crafts artists were drawn to the natural world for their imagery. Morris himself dismissed the exotic hothouse plants so popular with the Victorians and instead drew his floral motifs from his garden and the English countryside. Marigolds, honeysuckle, jasmine and lilies were among the flowers depicted in his wallpaper designs. Morris believed that the structure of patterns was of crucial importance, as he explained à ¢Ã¢â€š ¬Ã‚ ¦if the lines of them grow strongly and grow gracefully, I think they are decidedly helped by the structure not being elaborately concealed. His designs were rigorously constructed, on either a symmetrical diamond design framework or a branch framework that created a bower effect. Willow boughs or scrolling acanthus leaves were used as a structural background in a number of Morris designs. Many of his designs also included complex, subsidiary patterns of small flower growing from meandering stems. His insistence on the highest standards of design is apparent in this quotations: à ¢Ã¢â€š ¬Ã‚ ¦ no amount of delicacy is too great in the drawing of the curves of a pattern, no amount of care in getting the leading lines right from the first. Remember that a pattern is either right or wrong. It cannot be forgiven for blundering. A failure forever recurring torments the eye. William Morris (1834-1896). (images) Wallpaper analysis Morriss first commercial wallpaper designs, as can be seen in the first two images here, Daisy and Pomegranate, were very much a case of stamped motifs on a fairly simple and plain background. Some of the motifs were actually reproduced from Morriss medieval style tapestry work, usually from incidental backgrounds or lower foregrounds where they were used to fill in spaces around the more important human figures. Both Daisy and Pomegranate were produced in the mid-1860s and reflect very much the simplicity of much of Morriss early textile work. In fact, many of the designs initially produced for textiles did end up as wallpaper patterns, with very few changes in the design, if any. By the 1870s Morris wallpaper design work had become much more accomplished, and therefore much more complex. There is very little, if any plain background to be seen, and whereas the earlier examples were largely independently stamped on to a surface, the later examples are clearly intertwined with each other, making it difficult to see any obvious motifs. The three designs shown, Larkspar, Pimpernel and Chrysanthemum were all produced in the 1870s. They clearly show the confidence in the design work and the medium, and are therefore much more fluid and free form than the earlier, more tentative work of the 1860s. It would be tempting to see some of the fluid and meandering flower stems, rich, full flowers and languid leaves, as an indication of the roots of Art Nouveau, and while there is a certain similarity in some of Morris work, it is also firmly rooted within both the British Arts Craft movement and the styles and fashions of the mid-Victorian design world. What makes Morris wallpaper design work stand out from others of the same era is the intensity of the compositions. There is a real observational passion for the natural world that is missing from so much of Victorian floral derived work. To Morris, these designs could not just be interpreted as pretty, or attractive, they were much more. They were indeed part of his lifes work and passion. They were a record of the British traditional rural landscape, one of nature and human in a harmonic symbiosis. The intertwining of much of his floral work could be interpreted as a framework in which we are all a part, which is one of the reasons that Morris disliked geometry as a design tool, as he interpreted it as a man-made system for trying to quantify the natural world, rather than allowing the natural world to quantify itself. The Acanthus wallpaper The Acanthus has been widely used since early times. A plant with boldly indented and scrolled leaves; it was a common element in Greek and Roman architectural ornament as noted in chapter 1 and a widely used Renaissance Motif. It has appeared in textiles over and over again, from Italian velvets to Arts and Crafts prints. William Morris said of it, No form of ornament has gone so far or lasted so long as this; it has been infinitely varied, used by almost all following styles in one shape or another, and performed many other office besides its original one. Large lead verdure tapestries, employing foliage in soft greens, tans and browns on a dark blue background were manufactures in France and Flanders in the Sixteenth century and greatly influenced William Morris designs for wallpaper. Many designs of the 1890s including a number of William Morris prints incorporated the large swirling patterns of Acanthus scrolls or other classical floral motifs from the sixteenth and seventeenth century. (type up literature review) British Wallpaper in the 1970s The Revival of Art Nouveau in the 1970s Over half a century after the initial movement of Art Nouveau, it re-emerged for a second time in the 1970s. This however was not the only art movement that was rediscovered and re-energised in 1970s wallpaper design. The Art Deco movement was of particular interest which influenced two dimensional surface design, but also aesthetic qualities from a number of Victorian art styles were reincorporated including the works of William Morris and the Arts and Crafts movement. What where the reasons for the re-emergence of the Art Nouveau movement? However, the generation that came after the Modernist outlook the 1950s and 1960s, started to trawl through the ephemera that had been left behind by nearly a century of Victorianism. A new generation of textile and wallpaper designer, who had little if any of the prejudice against nineteenth century design that was shown by previous generations, were keen to examine the design work and if possible produce work that was inspired by the original, but with a contemporary twist. There was a wide range of work produced in this neo-Art Nouveau style. Some was close to the original idea of using florals and incorporating the sinuous line that was present in the original style. Interestingly however, although this seemed like a kick against the ideas of modernist design, many of the ideas and philosophies of twentieth century design were incorporated into these new Art Nouveau inspired patterns. Many of the colour schemes for example, were heightened and changed altogether to fit in with interior schemes that were based on an entirely different set of parameters than the turn of the century originals. There was also less of an emphasis on the portrayal of floral design and much more on a vaguer, even abstract quality to the design work, which placed the emphasis firmly on pattern and shape, rather than any form of representational design. Much of the design work reproduced here (refer to images) is interesting as, although it does represent a re-emergence of interest in past styles, it does not descend into pastiche or plagiarism of the original decorative style. This is not the Laura Ashley style of design, which was more or less a slavishly faithful copy of the period; it is more an interpretation of a design style as seen over the gulf of the twentieth century. Designers saw no point in reproducing faithful copies of the Art Nouveau style, as reproductions were already available. However, they also saw no point in producing new work that copied the style exactly as no one could pretend, as Laura Ashley did, that seventy years of the twentieth century had not happened. These Art Nouveau revival wallpapers give a fascinating opportunity to picture two points in the history of design, the gap between them and how that gap affected the process of design and interpretation. Wallpaper design was still popular in the 1970s, though beginning to lose out to painted walls. However, it was still a mainstay in many homes and would continue to be so for the rest of the decade. This popularity meant that the choice and range of design work available was fairly large compared to todays choices. Geometrically derived patterns, as the ones shown here, were still popular throughout the decade, as were all forms of floral, from the traditional realistically looking flower patterns, to popular graphic interpretations. All of the patterns shown here are of wallpaper designs from around the 1970s. They all take the flower as their source of inspiration and its subsequent decorative effect. All are basically flat pattern designs, some more abstract than others, but all still using the flower as a standard motif. Wallpaper Analysis Taking a flower down to its basic components, you are left with four petals and a circular centre. There are of course endless variations on this theme, with the petals multiplying or decreasing, though four tends to be the lower limit. The centres can also range from a fairly complex pattern with a number of different centres, to a very simple but effective circle. Some of the flower motifs in these examples have become little more than geometric shapes with the flower becoming so abstract that it is barely recognisable as such. However, that does mean that the design is not a floral, no matter how far removed it has become from the original inspiration, it could still justifiably be classed as a floral decoration pattern. Often, by including more than one type of flower motif, the pattern can take on a more complex appearance. In this way patterns can then sit within patterns, so while the petals and centre of the flower can produce a decorative effect within its own right, a self contained pattern, these can then be used as multiples, creating another pattern. If a different flower motif is then introduced, that flower has a decorative effect of its own and if juxtaposed with the original flower motif, they contrast with each other, thus creating yet another pattern effect. This can go on so that a number of more complex layers are added, though care should be taken not to overload the design, which can become confusing the more elements that are added. This can be a particular problem with wallpaper design whereby a pattern effect has to be able to be interpreted easily from a distance, but must also be effective when seen close up. Another interesting effect that can be used is when flower motifs overlap each other, creating an opportunity to produce yet another flower motif, and by changing the colour tone slightly, this new flower design will appear as if still connected to the overlapping decorative flower motifs, while retaining some independence from them at the same time. Colour and tone is an important element, particularly within flat pattern where it is sometimes difficult to give the design elements that make up the pattern enough differentiation for it to have any effect, particularly from a distance. By using similar colours or one colour with different tones, it becomes much easier to see separate elements of the pattern while still maintaining a balanced piece that appears to be both harmonious and effective. The art world has introduced countless ideas and methods that have been reinterpreted by both textile and wallpaper designers. Abstraction and colour and paint techniques in all their modernist facets, have been used repeatedly and constantly by designers who were keen to add to the repertoire of the industry. Large bold patterns, still with the flower as its centre of inspiration, have been part of the wallpaper industry for a long time. By interpreting and often reinterpreting for the medium concerned, effective large repeat patterns have been produced that seem to have little to do with a mass production industry, but are still mass produced nonetheless. These patterns often appear to be less constructed and less precise, often giving the illusion of spontaneity and creativity, the hallmarks or at least the common interpretation of much of the twentieth centurys fine art output. This is by no means a comprehensive interpretation of flat design. It only gives a few ideas as to the complex nature of this style of design and the number of variations that are easily achievable. In Conclusion flat design appears to be much more creative and inspiring than traditional floral realism for example, with endless opportunities to both simplify and complicate the same pattern motif. (Images of 1970s wallpaper) Methodology Introduction When embarking on a topic of research, all of the possible methodological factors must be taken into account as sources of information are of great importance. Decisions ave o be made into which method of data collection to use to achieve the greatest information specific to the question at hand. In order to try and find out as much information about the topic and area being disgussed, a variety of acedemic sources were needed, such as books, journals and the internet. These academic sources wer all accesed in a selection of different places. Despite a wide variety of ways to find all of this information, the information did not come without its problems. Finding the information There are many ways of findng the information that is needed. Most of the information in relation to this study was found in the university library in the textiles department. This was done by searching for and looking through relevant literature in the books that were available in the library. Finding books for relevant information was one of the first things that had to be done in order in order to find background inforation on the topic, such as what work had already been done in the area. Books were also then found in order to find informaton in relation to the question being asked through the use of search engines, which produces a list of books/journals with relevance to keys words, authors etc. The internet was also used as a method of secondary resourcing. This was used to find websites such as the Wallpaper History website which provides links of online aricles referring to the history of wallpaper and the innovations of wallpaper design. The internet also allowed journals to be found online, this allowed access to more up to date literature which was not provided by the available books in the library. Journals are also quick and easy to find, simply using the search engine tool online, a large number of journals become available to read. These journals were used in the same way as books, to find background knowledge and to help find information towards the question. The books and journals especially, helped to find vital information on the topics of the innovations of wallpaper design and how designers have put their own stamp on the very popular floral motif which has developed with te ever changing society. This is all acedemic wock which was needed in order to answer the question as thoroughly as possible. Interviews Interviews give a ricj insight to peoples biographies, experience, opinions, values, aspirations, attitudes and feelings. Interviews were taken place in The Temple Newsome Museum which is celebrated for its wonderful collections of fine and decorative arts, especially paintings, furniture, silver, ceramics, textiles and most importantly wallpapers. James Lomax the exhibition curator who specialises in the 17th 18th and 9th century was interviewd. This was to obtain an insight of a professionals view on the matter. Using interviews as methods of colecting data proved to be a reliable source of researc. This is because of the specific questions are asked with a reliable reply relating to the subject matter. Data can be obtained easily and resourcefully using certain questions. Interviews can be delivered in a structured or unstructures form. Consideration was given to the type of interview that was carried out to gain the best results. There are both advantages to consider when chossing the most appropirate one. Structured interviews are seen as having set questions. These questions are asked and recorded on a standardised schedule. The question cannot be modified during or after the interview. In contrast an unstrctured interview is less formal, where the interviewer has a greater flexibility and freedom. It was thougt that an interview towards the less structured theory would be more effective as the researcher did not want to domain the interview. Planning was essential for the process. Limitations Limitations include trying to find books that were relevant and that were also up to date. As a way of traking this because the university library only had a limited amount of books available on the floral motif, inter library loans were used, this is when books can be loaned form other university libraries. This however can be very time consuming because people may already have the books out and even if they havent it can take a few days before the ooks arrive to be collected. Another disadvantage of using the library which proved to be a problem in the stages of research was the opportunity for others to put a reserve on books which were already loaned out. This not only adds pressure to the researcher but limts the time available to read through the books and to thoroughly digest and understand the information provided.
