Katherine Mansfield Essay Example for Free

Katherine Mansfield EssayHer feelings of disjuncture were accentuated when she arrived in Britain in 1903 to attend Queens College. In many respects, Mansfield remained a lifelong outsider, a traveler among two seemingly similar yet profoundly different worlds. afterward briefly returning to New Zea knock down in 1906, she dissembled back to Europe in 1908, living and writing in England and parts of continental Europe. Until her premature death from tuberculosis at the age of 34, Mansfield remained in Europe, leading a Bohemian, unconventional fashion of life. The Domestic PicturesqueMansfields short story Prelude is set in New Zealand and dramatizes the disjunctures of colonial life through an account of the Burnell familys move from Wellington to a country village. The story takes its title from Wordsworths seminal poem, The Prelude, the first version of which was completed in 1805, which casts the poet as a traveler and chronicles the access of a poets mind. 4 Although the Burnell family moves a mere six miles from town, the move is not inconsequential it enacts a break with their previous mode of life and alerts the family members to the various discontinuities in their lives.Beneath the veneer of the Burnells harmonious domestic life are faint undercurrents of aggression and unhappiness. The haunting specter of a mysterious aloe plant and a slaughtered table in their well-manicured cubic gigabyte suggests that the familys awfully nice new home cin one caseals moments of brutality and ignorance toward an other way of life that was suppressed and denied. 5 As I leave propose, these two incidents echo the aesthetic concept of the lordly, as they encapsulate a mysterious place that awes its beholders and cannot be fully contained within their beautiful home.Through her subtle, dream-like prose, Mansfield deploys traditional aesthetic conventions like the picturesque while simultaneously transfiguring, subverting, and reinventing them in a mo dernist context. The concept of the picturesque was first defined by its originator, William Gilpin, an 18th century creative person and clergyman, as that kind of beauty which is agreeable in a picture. 6 Thus, a scene or representation is beautiful when it echoes an already-established, artistic conception of beauty, revealing the self-reinforcing way in which art creates the standard of beauty for both art and life.Mansfield presents these picturesque moments in order to demystify them and reveal the suppression and violence they contain. In addition to Prelude, her stories Garden Party and Bliss dramatize the transformation and inversion of picturesque moments of bourgeois life and domestic harmony. While she seems to exhibit a certain fastening to these standard aesthetic forms, Mansfield subtly interrogates many of these conventions in a strikingly modernist way. Through her childhood in a colony, Mansfield also became attuned to the violence and inequalities of colonialism. As Angela metalworker suggests, her early writings demonstrate a keen sensitivity towards a repressed history of brutality and duplicity. 7 In her 1912 short story How Pearl clit Was Kidnapped, she questions and all overturns the perspective of the colonialist, whose vantage point historically trumps that of the native. The deliberate ambivalence of the word kidnapping dramatizes the conflict between the colonists perspective and Pearls joyful, eye-opening experiences during her abduction. In a similar way, empire dramatized for Mansfield the way that a picturesque, bourgeois household could suppress alternative perspectives.The Sublime In Prelude, the mysterious, sublime aloe plant disrupts the nice domesticity of the Burnell household. Their well-manicured yard with its tennis lawn, garden, and orchard also contains a wild, unseemly sidethis was the frightening side, and no garden at all. 8 This side contains the aloe plant, which exerts a mysterious, enthralling creator over its awed beholders. In its resemblance to the ocean, the aloe assumes the characteristics of the sublime the high grassy bank on which the aloe rested rose up like a wave, and the aloe seemed to wind up upon it like a shop with the oars lifted.Bright moonlight hung upon the lifted oars like water, and on the green wave glittered the dew. 9 For many writers and poets, the ocean was a manifestation of the sublime because of its unfathomable power and scale that awed and humbled its observers. The aloes strikingly physiological effect on its viewers recalls Edmund murders sublime, which overpowers its observer and rein advertizes the limitations of man reason and control. In his famous treatise on the sublime, Burke writes greatness of dimension, vastness of extent or quantity is a powerful cause of the sublime, as it embodies the tearing and overpowering abilitys of nature.10 In a similar vein, the child, Kezia Burnells first impression upon seeing the fat swelling plant with it s cruel leaves and fleshy stem is superstar of awe and wonder. 11 In this case, the sublimity of the aloe plant disrupts and challenges the domestic picturesque as it defies mastery, categorization, and traditional notions of beauty. In its resistance to categorization and control, the sublime embodies the part of the ungovernable landscape that the Burnell family cannot train and the picturesque cannot frame.As a result, in Prelude, the magnitude of the sublime interrupts and fractures the tranquil surface of the picturesque by exposing the unfathomable depths beneath it. The colonial backdrop of the Burnells yard also contributes to the mysterious, occult power of the aloe. This unruly part of their property hints toward a landscape that eludes domestication and serves as a constant reminder that the Burnell family is living in a land that is not quite theirs and cannot be fully tamed.12 At the age of 19, Mansfield wrote that the New Zealand bush outside of the cities is all so gigantic and sadand even in the bright sunlight it is so passionately secret. 13 For Mansfield, the bush embodies the history of a people whose lives have been interrupted and displaced by European settlers. 14 After wars, brutal colonial practices, and European diseases had devastated the local Maori population, the bush became a haunting monument to their presence.As the Burnell family settles down to sleep on the first night in their new home, far away in the bush there sounded a harsh rapid chatter Ha-ha-ha Ha-ha-ha. 15 In her subtle way, Mansfield unveils the voices of those whose perspectives are excluded from this portrait of nocturnal domestic harmony. In a similar way, the aloe plant exudes an unfathomable history that is beyond the time and place of the Burnells. Even its ageimplied by the fact that it flowers once every hundred yearssuggests that the aloe exists on a different scale than its human beholders.16 In its ancient, superhuman scale, the aloe gestures towards t he gigantic, indicating a subtle, but implicitly threatening power within, or in proximity of the home. The aloe is a kind of lacuna in the imperial landscape of New Zealand, whose power threatens the colonial household and its control over the landscape. 17 By disrupting and encroaching upon the ostensibly safe domestic sphere, the aloe also echoes the unheimlich, or uncanny, an aesthetic concept explored by Sigmund Freud in his 1919 essay, The Uncanny. The uncanny becomes, in part, an invasive force violating the sacred, domestic sphere and hearkens back to a previously repressed or hidden impulse The uncanny is something which ought to have remained hidden but has come to light. 18 In Prelude, the aloe is initially depicted as a threatening force that might have had claws instead of roots. The curving leaves seemed to be hiding something. 19 Positioned within the safe post of their property, the aloe is a menacing, ungovernable force that seems to encroach upon it.The plant beco mes part of the repressed history of the landscapea history that is only apparent to Kezia, her mother Linda Burnell, and her nanna Mrs. Fairfield, who are attuned to the forces below the surface of the picturesque exterior. Violent Underpinnings Beneath many of Mansfields picturesque domestic scenes are moments of violence and rupture. In Garden Party, for instance, a poor man falls to his death during the preparations for a much-anticipated social gathering of the wealthy Sheridan family, undermining the convivial spirit of the occasion.In Prelude, Pat, the handyman, slaughters a elude while the children set with grotesque enthrallment as it waddles for a few steps after being decapitated. The crowning wonder of the dead duck walking hearkens back to Burkes sublime, which is experienced in Prelude within the confines of the private residence. 20 The sublimity of this apparent defiance of the properties of death acts as a dramatic external force imposing on the observers intelle ct and reason in a profoundly Burkian way.But later that night, when the duck is placed in front of the patriarch, Stanley Burnell, it did not prospect as if it had ever had a head. 21 The ducks picturesque dressingits legs tied together with a piece of string and a wreath of bittie balls of stuffing round itconceals its violent death. 22 In a similar way, the awfully nice picturesque house is imposed upon the landscape, as if it had never been any other way. 23 Through reconfiguration and transformation, a new imperial order conceals the fact that an older order once lay beneath it.In both cases, the picturesque functions as a way of naturalizing the violent order of domination. As Pats golden earrings distract Kezia from her grief over the ducks death, the ducks pretty garnish conceals its basted resignation. 24 There is no such thing as a pure aesthetics, Mansfield seems to suggest, as each serene moment is implicated in some act of violence, brutality, or suppression. In Prelu de, the good-natured Pat disrupts a pre- actual picturesque scene in which ducks preen their dazzling breasts amidst the pools and bushes of yellow flowers and blackberries.25 Tellingly, the duck pond contains a bridge, a typical feature of the picturesque that reconciles or bridges the gap between different aspects of the scenery. In this way, the Burnell familys cultivation of the land by planting and slaughtering ducks disrupts another underlying order. Their unquestioning appropriation of this pre-existing order mirrors the way colonial life disrupted and undermined the indigenous Maori life. Juxtaposing two picturesque scenes that interrupt and conflict with one another, Mansfield questions and unravels the conventional image of the picturesque.This interplay of various conflicting aesthetic orders constitutes part of Mansfields modernist style, in which aesthetic forms are ruptured, fragmented, and overturned. As the yards landscape bears traces of the Maori past, so the quiet harmony of the Burnells domesticity is underscored by deep, unspoken tensions and an animosity that hints at the uncanny. In fact, the only character who expresses any contentment is Stanley, who reflects, By God, he was a perfect fool to feel as happy as this 26 Yet even he shudders upon entering his new driveway, as a sort of panic overtook Burnell whenever he approached near home.27 Beneath this veneer of marital bliss and familial harmony, his wife Linda occasionally ignores her children and expresses hatred towards her husband and his aggressive sexual activity there were times when he was frighteningreally frightening. When she screamed at the top of her voice, You are killing me. 28 Meanwhile Stanley and Beryl, Lindas sister, seem to have a flirtatious, improper relationship Only last night when he was reading the paper her dishonest self had stood beside him and leaned against his shoulder on purpose.Hadnt she put her hand over his so that he should see how white her han d was beside his brown one. 29 Dramatizing these dynamics, Mansfield suggests that a happy household outside of town is not as dirt bargain-priced as Stanley boasts it comes at the cost of servitude, sexual aggression, and a ravaged Maori landscape. 30 Through these layers, which Mansfield subtly strips off one at a time, she artfully exposes the way that an existing political and aesthetic order is not what it seems to be or how it has always been.Her short stories are fraught with their own tensions while exposing the picturesque as false and absurd, she nevertheless draws on its conventional associations. Similarly, her subtle attempts to question colonial power are embedded in a seemingly idealized portrait of colonial life. Mansfield creates a seemingly beautiful or normal image, such as the happy family in Prelude, Bliss, or Garden Party, and then slowly challenges it through a subtle counter-narrative.In this way, her deployment of modernist techniques is less pronounced tha n that of James Joyce and her other modernist contemporaries. Just as she challenges aesthetic conventions, Mansfield unravels the readers ideas about her own stories by presenting a seemingly beautiful, transparent narrative that is haunted by tensions, lacunae, and opacity. Like the headless walking duck, these fictions of transparency and harmony quickly collapse upon closer inspection.

Future MBA Cartoon Essay Example for Free

Future MBA Cartoon EssayAmbiguity Friend or FoeOften times during our earlier years, we stumble upon loopholes within our language. We wherefore take these loopholes and mend them to our advantage. These loopholes that I am referring to are tidingss that have many different meanings, however actions john also be grouped into this. very much like the cartoon, Future MBA illustrated by Mike Shapiro.In this cartoon you see two students sitting at their desks, both with paper and pencil on the desk. The instructor is standing in front of them and unrivaled can only be brought to the assumption that these children were either taking a test or doing an assignment that was meant to be finished solo. However, this cartoon depicts that these students did not follow those instructions by giving us the text, We werent cheating. We were consulting. With this text we are given that the children are looking for a way out of punishment by re-characterizing their obvious but ambiguous act ions by altering what the teachers perception of it was with that of something that is not detestable, although kind of questionable. Cheating is the sharing of answers or ideas that one person may have and is given to another. With the idea that there was no cheating or answer exchanging going on but rather discussing possible outcomes, or consulting in this case, these children are efforting to pose the idea that they have done no wrong.This happens more often than you would think. Unfortunately, when these do occur it is not always in a less harmful situation such as a classroom setting over a test or assignment. This often happens in large business and even our government. Through the use of euphemisms you take a word that is particularly disliked and exchange it with a word that has more appeal. On the news for example when there are times of war and there are casualties. The word casualties take the place of saying quaternion women, seven children, and six men were killed. It can be used in this scenario where emotions could get the better of the situation and cause an uproar. However, is this right? Has our language helped us or betrayed us by making it so easy tocleverly deceive our minds from what is really going on? Then again, in situations it can help placidity the pain of loosing a loved one, and explaining it to a child. For instance, instead of telling a child that their father was decapitated in a car crash and is dead, we can tell the child that their father has passed away. In this case it is our ally.It is hard to determine whether something of this magnitude is beneficial or ultimately malicious. I can see both sides of this, but you cannot get rid of one without the other. They are two sides of the same coin. The only thing I can leave with you is that you cannot have the use of one without the other. However, I can tell you that you have to choose how to use this. Personally, I choose to use this for the greater good not to deceive ot hers or try to confuse them about what is really going on.Works CitedShapiro, Mike.

Russias Approach to Cyber Warfare

Russias Approach to Cyber state of warf arPolicy Briefing on the Imminent Russian Cybersecurity Threat The Need For Action Against Russian CybercrimesIn recent years, Russia has build a reliance on using cyberwar and crimes as a tactic to achieve their strategic goals both in their nest-abroad and against Hesperian countries. The linked pleads mustiness be prepargond to retaliate against any cyber clap tell at our nation by assessing options to limit and counter the Russians without leading to an all overescalation and possible war.BackgroundThe relative frequency with which we hear about Russian hackers hacking into a countrys all important(p) selective in categoryation and systems has become more and more regular, and as a result of this it is important to trace back the history of Russian cyber warf ar. The first instance of a large scale Russian cyber attack happened in Estonia in 2007. At the time, tensions were postgraduate between Russia and the former Soviet St ate, and the Kremlin authorized a trial which targeted Estonian organisational agencies and businesses through handling of massive DDoS (distri unlessed denial of service) attacks that shut down myriad websites essential to the functioning of these agencies and businesses (Batashvili). In 2008, Russia coordinated an even larger cyber attack during the Russo- tabunn War. On August 7, a cyber attack was conducted from Russia against Georgian government and media websites, maculation at the comparable time Russian troops were crossing the Georgian border. According to the Report of the Independent International Fact-Finding Mission on the impinge in Georgia, the attack lead to several Georgian servers and high amounts Internet traffic be taken envision of and placed under external control (Batashvili). The offensive persisted through the conflict lasting until ceasefire was announced on August 12. Furthermore, the Kremlin had tested their abilities in the lead up to the impac t, shutting down the official website of the death chair of Georgia for an entire day on July 10. The Russian cyber attacks affected practically all Georgian government websites, crippling the states might to suffice to the conflict. Additionally, attacks targeted Georgian media, business, and some other(a) governmental organizations in order to control them from turning the conflict away from Russias favor by making it difficult for information of what was happening inside of the conflict zone to spread out to the rest of the instauration. According to a report by the US Cyber Consequences Unit, the primary objective of the cyber campaign was to support the Russian invasion of Georgia, and the cyber attacks fit neatly into the invasion plan. The attacks achieved their intent, since they world-shakingly impeded the ability of the Georgian government to deal with the Russian invasion by interfering with communications between the government and the public, stopping many payme nts and financial transactions, and causing confusion about what was happening (US Cyber Crimes Unit).Recent cyber attacks against Ukraine are a worrying signal of a continued exercising of this strategy. Ukrainian president Petro Poroshenko said that during in the final two months of 2016, Ukrainian state institutions had 6,500 instances of hacking, most directed towards the ministries of defence and finance, in addition to Kievs power grid and the treasury. According to the Poroshenko, the operation came at the hand of the Russian security services, following the same playbook as they had in Georgia (Batashvili).Russian cyber operations are not use solely in tandem with array offensives however, with many excessively universe employed in the wars on information, especially against Western nations. The 2016 American presidential election, while highly publicized is not the barely instance in which at that place is evidence of Russian interference with the 2017 French and Germ an elections also creation targeted. Numerous French officials and agencies, including the Defense Minister and DGSE have raised concern over the issue of Russian interference in the nations election, citing concern that fake news and cyber attacks were being directed to now President Macron and his party as they were not the candidates the Kremlin believed would be most beneficial to the Russian state interests. German intelligence agencies have also brought up similar concerns about Russian cyber activities being directed against Germany and its election, with Chancellor Angela Merkel, herself seeing attacks as threatening the foundation of German democracy and the effective functioning of the German state (Delker). Russian Objectives As right today, Russian use of cyberwarfare has three common and consistent objectivesCapturing Territory Without Resorting to Overt orConventional Military ForceThis was the strategic goal we sawRussia laborious to achieve in 2014, when they vi ctorfully annexed Crimea. Theannexation of Crimea relied on a group of Russian Special Forces operativesknown as the little green men, who took their directives from a newly createdRussian special operations command. The deployment of these highly trainedoperatives, in coordination with a massive information warfare campaign, aswell as the affair of local Russianloyalist proxies created the opportunity for Russia to takeover without needingto shed blood as they had forced momentum to shift in their favor allowing forCri message in Ukraine to voter turnout for secession from Ukraine (Chivis). In 2008,Russia used similar tactics in its invasion of Georgia, during which they similarly coordinated cyber attacks against essential government computingservices while at the same time operating special operation forces incoordination with Russian loyalists from the Georgian State. A major impact ofthese tactics has led to a weakened ability to integrate these countries withWestern though t. In 2013, Russian Chief of the General Staff, General Valery Gerasimov describeed Russias current views on such hybrid cyber warfare tactics, stating that in modern conflicts non- war machine means are put to use more than 4 times as often than are schematic soldiers operations (Gerasimov). This suggests in the future such cyber attacks will be likely, and even at this point many are not being properly identified. In its use of cyberspace, Russia has shown it can come across conquest in achieving territorial expansion goals in a manner that is nonviolent and seemingly peaceful, however there is always the underlying threat of actual military force being used unsparingly. Creating a Pretext for Overt,Conventional Military ActionIn a similar manner to capturingterritory through covert, non-militarial expansion, Russia is also capable ofusing cyber warfare in order to create a conflict which gives them solidreasoning to use military force in unconnected nations (Chivis). For i nstance, theRussian annexation of Crimea has lead to a reasonable concern that the Kremlincould engage in a hybrid strategy to manufacture a conflict valuable of militaryaction elsewhere, possibly the Baltic states. As it did in Crimea, Russia couldtry to create tension in a country like Estonia by conducting a campaign whichfoments discord between the minority Russian population and the Estonians. Increating these sentiments which portray the government of Estonia as oppressivetowards the minority Russians, the Kremlin can justify a Russian militaryintervention their behalf of the Russian minority, as Russian sentiment stillsees these race as their own. Conducting an operation of this sort overlooksthe accompaniment of simultaneous cyber operations directed at inflamingattitudes and creating difficulties in executing both national and NATOresponses. It would almost certainly be accompanied by efforts to influencebroader European and world opinion in ways that favored Russias int erventionthrough use of propaganda and opinion shifting which portrays Russia as actingon behalf of a repress population that seeks its aid. On the ground, it wouldinvolve the use of Russian secret agents and proxies, both to act asaid/support for local populations creating tensions, and to coordinate withmilitary forces awaiting bid and guidance.Using Hybrid Measures to Influencethe Politics and Policies of Countries in the West and ElsewhereThis last objective is the mostpressing for the United States and Western countries out of the near vicinityof Russia. In this objective, the Kremlin seeks to use cyber operations in lieuof military action or war to create tension and distress in Westerngovernments. The goal of this strategy is to influence and create favorablepolitical outcomes in targeted countries to serve Russias national interests(Chivis). The countries where these types of operations are most likely to findsuccess are those with high levels of corruption and weak legal systems.However, more stable countries such as the United States and the United Kingdomare similarly susceptible to such operations. Examples of ways the Kremlin canengage in cyber operations to influence an outside nations political systeminclude the use of fake troll accounts used on social media to spreadpropaganda and create divides amongst the citizens of that nation. Also thehacking of servers of government officials can provide them with material whichthey can use to every influence that official through blackmail, or which canbe leaked to induce further tension. In creating these narratives, Russia hasthe ability to influence democracy by planting anomalous information andmanufacturing biases against those that act against the interests of theKremlin.American StakesThe continued use of cyber attacks by the Russian government brings up very realistic threats both domestically and internationally for the United States.Internationally as Russia continues with their their goals of territorial expansion, the United States is faced with the concern of a wider influence of Russian thought and expansion of pro-Russian policies in areas where the United States has worked to tug democracy and peace. The desire of Russia to reassemble the Soviet Union remains very real, and as seen in Estonia, Georgia, and Crimea cyber attacks can play a recognize role in these territorial gains. By allowing continued expansion of the Russian state, the United States risks losing the strategic relationships they have developed with these countries as well as the progress they made towards conclusion them more independence from Russia as democracy began to take its roots in these nations. Furthermore, these attacks can be used by Russia in places like Syria as a way to promote the Assad regime which works in coordination with Russia in achieving other strategic goals, such as the development of an oil pipeline through Syria. Domestically, Russian cyber attacks can destabilize the US government by creating rifts and tensions amongst the American populace through the spread of false information and fake news. As seen by the hacks against the DNC as well as the use of trolls during the 2016 Presidential Election, Russias use of cyber attacks can undermine American democracy by allowing for a foreign nation to change the minds of our citizens, feeding them lies and inflammatory material to create disarray in our democracy. This is especially hurtful as Russia can cite American disorder as a reason to not take our example and implement democracy in the American fashion to foreign nations. fervours by Russia can also cripple the governments ability to function towards the service of its citizens. Government Organization for a Cyber Attack The 2016Presidential Policy Directive (PPD) 41 United States Cyber IncidentCoordination defines a significant cyber attack as likely to result indemonstrable harm to national security interests, foreign relations, thedomes tic and global economy, public confidence, well-behaved liberties, or publichealth and the safety of the American people. (PPD 41). Cyber attacks byRussia against domestic communication or life-sustaining IT floor fall underthis classification.Should such anattack actually occur, the National Cyber repartee Group would lead thedefensive response as an arm of the National security Council (PPD 41). TheSecretary of Defense, in tandem with the directors of our intelligence operation agencieswould be responsible for managing incoming threats, and coordinating anystrategy or movement that would require active military response. In the eventthat the telecommunications systems of the National Security and EmergencyPreparedness sector fail, the National Coordinating Center for Communicationswould be tasked with re-establishing communications. Furthermore, PPD 41stipulates that if an operation with clear attribution is found to haveoccured, the Cyber Response Group shall assemble a tea m of qualified andskilled cyber personnel to respond to the cyber incident. This response teamshall have experience together in the form of practice sessions and war games. U.S. Strategic Responses After addressingthe immediate effects of a Russian cyber attack, its imperative the UnitedStates consider its options of strategic and tactical responses. one(a) option forthe United States is response through non-military means such as indictment,diplomacy, or sanctions (Bate). A lower-level military and intelligencestrategy that could possibly be employed by the United States is the use ofcounter-surveillance intelligence operations, non-attributable cyber orconventional attacks, or attributable cyber or conventional attacks (Herb).These operations would target Russian military, civilian, or criticalinfrastructure systems. Since NATOclassifies cyberspace as the fifth operational domain, it is likely that if theUnited States identified a significant cyber incident against its citizens a soriginating from Russia, their response would come in the form of aggressivecyber tactics. The possibility of conventional military expeditions may beexplored, however the risk of further escalation makes it more likely that theUnited States respond only through cyber operations. Low-Level Attributable Cyber Intrusion One possibleresponse the United States could utilize in retaliation to Russian cyberattacks is low-level cyber intrusion, distributed across a array of cyberincidents that could not be collectively categorized as a major attack. Thisintrusion would appear as a result of what is called loud cyber weapons,which are tools that can be traced back to the U.S military (Herb). The USmilitary would send these weapons, embedded with encrypted codes, into Russiannetworks. The United States would then publicly provide the encryption key toend the intrusions caused by these weapons as a way to claim responsibility forthe attack. The purpose of taking credit for the attacks is a key paradigmshift in U.S military strategy, now emphasizing attribution as a key aspect ofa successful operation, and public knowledge as vital for deterrence. TheUnited States also has the option of conducting more basic cyber attacksagainst Russias network, including by not limited to alteration of governmentwebsites, disruptions of Internet service, interferences and disablements ofcommunications, or the spreading of propaganda (Department of Defense righteousness ofWar Manual). In the aftermath of the hack of the DNC, senior officials weighed optionsfor counter attacks on the Russian Federal Security Service (FSB) and the MainIntelligence Agency (GRU), including the use of the NSAs TreasureMap tool,which tracks all global connections to the Internet, and can be utilized toinstall malware in targeted Russian computer systems with the purpose ofintelligence gathering and future cyber-assaults (Bamford). Medium-Level Cyber Attack -No Immediate CasualtiesThe United States also has to ability toemploy the use of logic bombs in cyber operations targeting both military andnon-military targets in Russia. Logic bomb are codes developed with thepurpose of overloading a computers system rendering them incapable to operateby presenting them with an endless amount of logic questions to answer. Sendingthese logic bombs into computer systems critical to Russias infrastructurewill lead to the United States causing dramatic economic and operationaldamages to the Russian government and its people (Sternstein). The UnitedStates has invested a large sum of money into the development of these logicbombs, with initial investment coming back in 2014 when U.S. Cyber Commandoffered a $460 one million million million contract to develop a computer code capable of killingadversaries.(Storm). High-Level Cyber Attack Possible Casualties The United Statescould use logic bombs or other cyber intrusion methods to attack Russiancritical infrastructure in a more serious fashion, leadin g to a largerpotential for loss of homophile life or safety. These attacks include targetingsystems such as those of a dam above a populated level where a hackingcould lead to floodgates being candid onto Russian citizens, or disabling airtraffic control services leading to air safety where planes pose a threat toeach other and the land beneath them. These options, particularly if they areeasily traceable, have the potential to escalate quickly into furtherintensified conflict.Military-Level Cyber Attack Escalatory The United States also has the ability touse similar cyber operations to directly attack Russian military targets, withpossible targets including the shut off of power at a nuclear expertness or anairfield, which will lead to the cause of serious casualties. These attackswill most definitely lead to a triggering of a notable escalatory threshold ofresponse by the Russians. It is significant that many Russian industrialnetworks run computer systems operating Windows XP , and in some cases evenolder systems, while maintaining connections to the Internet. Not only are thesedated systems particularly vulnerable to attack, as evidenced by the UnitedStates already demonstrating its ability to break into these systems. InNovember 2016, the United States reportedly penetrated Russian militarysystems, leaving behind malware to be activated in retaliation in the case ofRussian interference of U.S. elections (Dilanian et. al). This demonstratedboth confidence in the success of the malware implant, and politicalwillingness to trigger a consequential conflict given Russia attacks the UnitedStates in a serious manner (Bernish).Strategic Considerations for U.S. Decisions In response to aRussian cyber attack, the United States strategic responses should be a resultof its classification of the attack as being non-significant, significant, oran act of war. State Department Cyber Coordinator Chris panther said the UnitedStates would respond to incidents on a case- by-case basis in testimony beforethe House Subcommittee on culture Technology and National Security in November2016, saying that retaliation could be through cyber means. It could bethrough diplomacy. It could be through indictments and law enforcementactions.(Pellerin).Some of theseresponses require action while others do not the path taken must be dependenton actual and anticipated effects of a cyber attack, including damage, injury,and death. Painter testified that, cyber activities may in certaincircumstances constitute an armed attack that triggers our inherent right toself-defense as recognized by Article 51 of the U.N. Charter(Hearing on Digital Acts of WarEvolving the Cybersecurity Conversation). The United States could also identify acyberattack as being an infringement upon its territorial integrity andpolitical independence, per Article 2(4) of the Charter. However, recentpolitical happenings indicate that the United States would be hesitant ininvoking Article 51, regard less of whether a Russian cyber attack lead to tokenish death, injury, or damage. Instead, the United States could limit itsdeclarations and address the attack as a significant cyber incident, invokingthe full support of the U.S. military while avoiding over-escalation.Furthermore, even though NATO justifies military response in the realm ofcyberspace, the lack of precedent means that the United States actually hasmore options in responding to Russia if it were to employ use of cyber means,that may or may not lead to conventional consequences. The United States wouldneed to decide between conducting a covert or overt counter-cyber attack. Thetactical considerations noted above show that hidden, non-attributable cyberattacks do not fall within the Department of Defenses deterrence strategy, andwould not be treated as a suitable strategy. In the aftermath of the 2014 SonyPictures hacking by the North Korean government, the United States didntrespond with a public cyber operation, and it was unclear how the UnitedStates may have retaliated against the North in secret, if it even didso.(Sanger). The lack of a publicly noticed retaliation as well mild economicsanctions now seems ineffective as punishment. A status could come up thatwould give the United States the opportunity to execute an immediatelyobservable cyber attack or a preparatory attack (logic bomb), with the targetbeing either a Russian military or civilian infrastructure. Similar to Russia,the United States should also avoid directly targeting a military structure inorder to avoid escalation to full-scale war. As a result of this, the UnitedStates should choose to deploy a cyber weapon against critical Russianinfrastructure, leading to conventional consequences being faced by Russia.Even the use a medium-level choice in terms of retaliation, would requireglobal ramifications to be taken into account. Even still, it ismy testimony to engage in a retaliatory strategy, which employs the use ofboth a com bination of an observable cyber attack through use of loud cyberweapons and logic bombs against significant parts of the Russianinfrastructure. The United States cannot allow Russia to attack them and takeglobal credit for the attack without retaliating in some way to show dominanceover Russia. Loud cyber weapons are particularly suitable for retaliationthat the public is aware of and will show the world that the United States isnot only willing to retaliate, but is better skilled in cyber war and confidentenough in its abilities to retaliate swiftly. Logic bombs targeted againstnon-military sites that still hold significant value to Russian infrastructurewill be the second leg of the suggested attack. The crippling of essentialinfrastructure will both warn the Russians that an attack on us will be metwith an attack that hurts their citizens and keep them from being able toretaliate back since they will not have the resources to come back at theUnited States.

What Is Spiritual Formation Religion EssayWhen asking the question, what is unearthly formation, there can be corking difficulty in recognizing the specific subject area of focus. This would be due to the great amount of variety within the stint of such(prenominal) a topic regarding the presuppositions many people can bring to it. However there is a consistent undercurrent that ties the definitions together into a telling coherent understanding. According to Dallas Willard, spiritual formation is the process where one moves and is moved from self- idolize to Christ-centered self-denial as a general condition of life in Gods present and eternal kingdom.1In this, there is a more detailed analysis in describing its meaning. Spiritual formation begins with God and the relationship with him and fellow brethren. It is by virtue of the Holy Spirits work in regeneration and conforming the believer into the image of Christ through his indwelling, guiding, gifting, filling, and empowerin g those saved for Gods glory. The foundation of such a formation is found through the Scripture as the yet and primary source of all truth. The responsibility of the Christian is a relentless pursuit in being Christ-like in all facets of life through a new nature. Such formation is the fruit of what one has already become, an adopted child of God, and not works alone to achieve an imaginary level of spiritual attainment. The methodology of such an endeavor is not prescribed as a checklist for every believer, but rather differentiates for each person as God sees fit for them.Biblical InstructionAs stated in the introduction there is a good turn of reference points pertaining to Biblical instruction regarding spiritual formation. Although such terminology is not specifically found in every instance, the idea in what it represents is plentiful. The primary area many refer to is the fruits of the Spirit in Galatians 522-23. With this area of Scripture, the results are listed from le ading a life under the guidance of the Holy Spirit. It would be considered a measure of progress in some ways to see how one is coming through the sanctification process. It should be noted, however, that there would be an ebb and flow to such a device in that some seasons may be more fruitful in patience and love as opposed joy and quietude introspectively. In order to attain such fruits however, one must be diligent to know the One in whom he is following. A thorough athletic field of His attributes that which makes up His character, is imperative in attaining any growth whatsoever. Through such acquaintance is a child of God to begin the process in a more fruitful way than foregoing it. Without this concrete foundation, some(prenominal) of the growth will be experience alone, which is not biblical. Knowing who Christ is through his attributes is the only way one can attain the spiritual growth as guided by the Holy Spirit.From this one should then go to the Sermon on the Moun t in helping to determine what a Christian should look like. The descriptive values in what and how the Christian should be would more readily represent into the fruits seen previously. Christ teaches what the believer must be like as a standard of behavior and life within the heart in accordance with the theology of God. Being separate from the instauration and unto Him is a fundamental truth that without, one cannot attain the fruit of the Spirit. The division of what should be done and what should be avoided, in essence, what delineates the world from those chosen of God instills the rock of truth to rely uponPersonal ExperienceIn reflecting upon ones own experience in relation to spiritual formation, a great number of those who call themselves Christian can only describe such a term as prayer time and possibly praise and worship in certain circles. For the most part it is classified as an emotional experience one has with the work of the Spirit. The form that it arrives is th rough clearing the mind or through music in service. These functions among others are more related to tradition than Scripture. In personal experience, it becomes a more concrete arena. What Scripture says to do, do. What Scripture says not to do, do not do. In this there is a certain requirement to know the difference and that itself can only be accomplished through much work and study in Scriptures. Most who identify as being Christians who want a greater awareness of God actually looks for and attains a easier yet non-Biblical methodology of self-interpretation apart from Scripture. There is no work in exegetical discernment and simple prayer in acquiring a greater knowledge of God which, then, leads to the greater awareness of Him. One cannot occur apart from the other, no matter how trivial the spiritual exercises may be.Coincidentally, it is in Westerhoffs work that sees both sides of the expunge blended into one unifying theme. In his chapter discussing the development of sp iritual discipline, there are areas that are beneficial to the Christian and areas that are not. Coincidentally, those that do help get out more with the external as opposed to the internal. Finding a time and place that is consistent in reading Scripture helps to develop a trunk which coincides with repetition in going back to the Bible daily. Journaling helps in recalling areas one believes the Spirit is taking him in relation to any given question or issue currently being dealt with. It also provides a timeline of posterity for future generations to read through. A spiritual friend which is a fancy way of construction Christian Brother is good for edification and encouragement through prayer and study time. Coupled with these areas are exercises that dwell on the internal of the person involved. Picturing, pondering, and praying of the Lectio Divina borders on the Eastern Mysticism and Catholic heritage of attempting to draw closer to God through works. In clearing the mind of no thought, breathing exercises, good posture, and ingeminate a mantra to better focus on Scripture only clears the way for self-reflection unto sanctification.2ConclusionThe entire effort of Spiritual Formation as a firm combines the Biblical with the non-Biblical under the contemplative ministry. It is rooted in Catholic pietistic mysticism with its emphasis on discipleship. It is espoused of righteousness by works by attempting to reach God by its own strength. Many Christians, who do not study as they should, take for granted what is spoken to them by leaders in the church service in whom they trust, and assume it is true. It has been attributed to CH Spurgeon of the saying, Discernment is not simply a matter of telling the difference amidst what is right and wrong rather it is the difference between right and almost right. It is in this piece of wisdom the Christian should reflect upon when determining whether they should follow to the letter that which is summarily groupe d under Spiritual Formation.

Computer Guided Template-Based Dental Implant

Computer Guided Template-Based Dental Im stick outtAbstractThe introduction of implants to tooth doctorry has attend toed umteen edentulous patients to make a to a greater extent than infrangible functional and esthetic alternative to fixed and removable prosthetic appliances. The optimal 3-dimensional positioning of the implants secures the best function and esthetic of the final restoration and at the same time avoids the bio mechanic complications and failure that might take place subsequent to the wrong positioning of the implants. The aim of this image is to highlight the importance of placing the implants in the optimal three-D position. Computer guided usher-based implant placement exit be discussed as a precise and inevitable tool in the readiness and in the execution of the implant placement. The objective is to enable the placement of the implant in a way that secures the highest predictable success with the least complications. Materials and Methods Out of 3 50 downloaded relevant articles only 161 articles were elect and referenced. The excluded articles were either written in langu successions other than English, descriptive of new fabrication methods of surgical guides, single case reports or experimental d genius on low-pitched sample sizeless than 5. Results Most of the revise papers are case series or experimental studies d unmatched on animals or cadavers. regular(a) the opinionated reviews were based on those articles. Computerized tomography (CT) and interactive comfortable ingest programs are proven to be important for faithful word planning. The accuracy of transferring the discussion plan precisely by the aid of CAD/CAM fabricated surgical guide to the patient mouth are inform to be more predictable than unornamented hand implant placement especially in the compromised cases. Conclusion The published literature highlighted the higher predictability, accuracy and precision of computer guided templet based implant placement over conventional free hand placement only when supporting strong evidence is lacking. Good controlled clinical studies with coherent term follow up is need in this regard. For the time being and with the reported high success of conventional free hand implant placement, it seems that free hand implant placement seems to be predictable at least in the hands of experts or with the uncompromised cases.IntroductionIn the 19th century many aspects of life were affected by the industrial revolution, especially in sciences and manufacturing. Dentistry was non an exception of this. However, it was in the Victorian era when the basis of modern alveolar consonant care was first set. A large function of the developments in dentistry were just modifications of industrial inventions. Many of such developments were impossible before the introduction and practise of electricity, which led to the invention of more complex surgery equipments Gelbier S, 2005. Another very importan t development took place as a consequence of the invention and the single-valued function of computers in the various fields of dentistry Schleyer Titus K.L., 1999.Computer guided implant placement is one of the aspects that shows how dentistry has got use to the computer and its science Azari A. and Nikzad S. 2008.In fact, it is true that the attainment in dentistry and the increased public sensation public of the importance of keeping their teeth healthy cave in led to the decreased frequency of edentulism. such(prenominal) declination varies not only among different countries but also among the different geographic regions within the same country and among the different groups of people of different cultural and social backgrounds. However, it is predicted that in the next few decades, there entrust be very low proportions of edentulism in elderly persons (over 65 years). Teeth outrage increases with age, this mover that in the future edentulism will occur at later stage s in life Lang NP Muller F. 2007 Lang N.P. De Bruyn H., 2009. In such situations and in addition to the innate delays in the healing of elder individuals Goodson 3rd WH Hunt TK 1979 the patients at that age will be most properly affected by co-morbidities and reproachful agedness gibes like osteoporosis, uncontrolled diabetes mellitus, hypothyroidism and chronic renal disease which are among the diseases that negatively affect the operating system quality and consequently implant success. Some older age related diseases like Parkinsonism, Alzheimer groundwork affect the ability to perform adequate oral hygienics and this may gratuity to inflammation and gussy up loss almost implants Roberts WE. et al.1992 Elsubeihi ES. Zarb GA. 2002 Marder MZ. 2004.For this, alveolar consonant professionals need to develop their scientific disciplines and to use new techniques that offer the patients with the safest, accurate results and the least morbidity and to be able to manage suc h elder patients and their unfavorable conditions which sometimes may preclude the placement of the implants Lang NP Muller F, 2007 Lang N.P. De Bruyn H., 2009.Back groundTraditionally, lost teeth were replaced by removable partial tone dentures RPD, fixed partial dentures FPD and complete dentures in cases of full edentulism Bragger U et al 2005. Since the introduction of implants to dentistry by Branemark1977, many of the edentulous patients throw been able to have more reliable functional and esthetic alternative to fixed and removable prosthetic appliancesLang N.P. De Bruyn H., 2009. The increasing Demand for implant retained restorations in the last few decades resulted in the need for new improved techniques to ensure the most proper implant position to restore the patient properly Ganz S.D,2001 .Historically the implants were placed where there is get up Kopp et al 2003. They were considered successful when integration is achieved Branemark et al.1977. However, as the functional and esthetic demands of the patients have increased signifi jackpottly the success of implant-supported restorations is no more only related to the take of implant integration in the bone but also to the proper positioning of the implants and subsequent prosthetic outcome Lal et al.2006. For this proper interposition planning has give-up the ghost mandatory. The main goal of the treatment plan is to place the implants in the optimal position as dictated by function and esthetics of the definitive restoration. This in turn avoids the biomechanical complications and failure that might take place subsequent to the wrong positioning of the implants Garber DA Belser UC. 1995 Kopp et al. 2003 Park et al. 2009.The aim of this project is to highlight the importance of placing the implants in the optimal three-D position. Computer guided template-based implant placement will be discussed as a precise and predictable tool in the planning and in the execution of the implant plac ement.The objectiveis to enable the placement of the implant in a way that secures the highest predictable success with the least complications.Materials and MethodsMultiple searches have been made through Science Direct and Google Scholar. The following key words were used with different combinations systematic review, computer-guided, computer-assisted, image-guided, robots, dental implants, complications, treatment planning, radiography, computerized tomography, accuracy, flapless surgery, zygomatic implant, bone density, augmentation volume, warm loading, free hand surgery, Steriolithographic templates. As the topic of computer guided implant placement is a modern topic the selected articles were expressage to the articles published from the year 2000 up to 2010. However some older but relevant articles were hand searched, selected and referenced. Almost 350 articles were found to be relevant to the different points to be covered in the project were downloaded after reading the ir abstracts it was found that many of them were either clinical case series and reports or experimental studies made on animals or cadavers, many of the systematic reviews were found but again nearly all of them were based on the mentioned articles. The articles of single case reports and the experimental studies with very small sample less than five size were excluded. Also, the articles that focus on the fabrication of new surgical guides were excluded. Articles in languages other than English are excluded too. Only 161 were selected and referenced in this project.ResultsMost of the revised articles concerning the accuracy of CAD/CAM template based implant placement are case series or experimental studies done on animals or cadavers. Even the systematic reviews were based on those articles. Based on the revised articles computerized tomography (CT) and interactive software program programs are proven to be important for accurate treatment planning. The accuracy of transferring the treatment plan precisely by the aid of CAD/CAM fabricated surgical guide to the patient mouth are reported to be more predictable than free hand implant placement especially in the compromised cases.DiscussionComplications associated with improper implant positioningMarginal bone loss and consequent mechanical and esthetic problemsThe correlation of marginal bone loss and improper positioning of the implant is reported in the literature. The wrong angulation of the implant is commonly compensated by the use of angled abutments, in this situation the load carried by the implant is mostly off-axis, such unfavorable load leads to the bone ravaging almost the implant and other mechanical complications like screw loosening, fracture and/or implant fracture Chun-Li Lin et al., 2005 Saab X. E. et al 2007.The improper placement labially, will lead to thin labial bone and subsequent bone loss and gum recessionBuser D. et al. 2004, linguisticly, in addition to the thinning of lingula bone it results in emergence problems as seen with ridge-lap restorations. Such restorations are difficult to maintain and consequent inflammation and bone loss is unavoidable Tarnow DP. 1995 Belser UC. et al. 1998. The placement of the implant too close to the adjacent tooth gouge cause resorption of the inter-proximal alveolar crest Esposito M. et al. 1993 Thilander B. et al. 1999. If the implant is placed too far apically using extensive countersinking, the polished implant collar will come into contact with the bone and this in turn induces bone resorption because polished surface does not integrate Buser D. et al. 1991a Hmmerle et al. 1996, also the micro gap will come closer to bone and unnecessary bone loss will take place. Disuse atrophy due to subnormal mechanical stimulation is other explanation for bone loss around polished implant neck or crest modulous Al-Sayyed, A. et al. 1994 Vidyasagar L. Apse P. 2004.Nerve injuryAltered sensation of the overthrow lip as a result of inferior alveolar face injury is one of the serious complications of mandibular implant osteotomies Bartling et a. 1999 Vazquez L. et al. 2007.This is especially if the magnification agentive role on the panoramic radiograph is misinterpreted Vazquez L. et al. 2007.The injury of the mental nerve dejection also lead to the same symptoms the mental reprieve is an important landmark during surgical procedures in the lower premolar area. it is usually located at the apex of the second mandibular premolar or in the midst of apices of thetwo premolars. However, in some cases its reparation can vary from the mandibular canine to the first molar. Unfortunately, The foramen may not appear on conventional two dimensional radiographs, in this condition a computerized tomography (CT) scans are important as they are more accurate for the detection of the mental foramen than conventional radiographs Bartling et a. 1999 , Greenstein Tarnow, 2006.Lingual massthough it is rare complicati on, the wrong implant placement in the lower jaw may lead to the perforation of lingual cortex with a great guess of lingual bundle injury with a subsequent fatal bleeding and hematoma formation. Under the effect of profuse bleeding and as a result of the progressive enlargement of the lingual, sublingual, sub- mandibular, and sub-mental hematomas the tongue and the floor of the mouth can be displaced leading to the rapid and complete obstruction of the airway Mordenfeld A et al. 1997 and Kalpidis Setayesh , 2004.Devitalization of the adjacent teethIn addition to the risk of losing the inter-proximal bone Esposito M. et al. 1993 Thilander B. et al. 1999 the placement of the implants in close proximity to the adjacent teeth may lead to the loss of the teeth vitality especially if the roots are injured during drilling for implant placement Jemt T. Pettersson P. 1993 Rubenstein J.E. Taylor T.D. 1997 Goodacre CJ. et al. 1999 Schwartz-Arad D. et al. 2004.Other possible rare but seri ous complicationsSome other rare complications can take place due to poor treatment plan and wrong implant placement like perforation of nasal and sinus floor Nahlieli O. et al 2008,injury of the submandibular and/or sublingual salivary glands Nahlieli O. et al 2008,mandibular fracture especially in osteoporotic and atrophied mandible Raghoebar G.M. et al.2000 Meijer H.J.A. et al. 2003.Criteria of optimal implant positionThe ideally placed implant should be surrounded by uniform bone volume and density this provides the implant with a good bony support against the multi directional long term loading. A minimum of more than 1 mm bone thickness is recommended to keep around the body of the implants Nancy L.C., 1993. In addition, the implant ideally should be placed in the geometric centre of the crown this reduces the off axis loading and prevents many of the biomechanical complications and its subsequent poor esthetic outcomes Galanis C.C et al. 2005 2007.Implant tooth distanceA min imum of 1- 1.5 mm distance between the implant surface and the adjacent teeth needs to be respected Buser D. et al 2004. However, a 3 mm distance between the implant and an adjacent natural tooth is recommended to minimize the potential for damage to the supporting structures of the natural teeth Adell et al, 1986 Hobo et al, 1989.Implant to implant distanceTo avoid bone resorption in-between the adjacent implants a minimum of 3 mm inter-implant distance is recommended Hobo et al, 1989 Traini et al. 2007.Implant to vital structure distanceTo avoid nerve injury during implant surgery in the mandible, some guidelines should be considered with respect to verifying the position of the mandibular and/ or the mental foramen and to validate the posture of the anterior loop of the mental nerve. These guidelines included leaving a 2 mm as safety device zone between the implant and the nerve. Once the safety zone is identified, implants can be placed safely and before the placement of any i mplant anterior to the mental foramen that is deeper than the safety zone, the mental foramen must be explored to verify the possibility that an anterior loop is there Buser Von Arx 2000, Greenstein Tarnow, 2006. In consideration of the risk of surgical complications during implant placement, bone grafting or other surgical procedures where risk is anticipated, a CT examination should routinely be performed before any surgical accession Ganz S.D,2001 Scaravilli MS, et al 2009 Naitoh et al. 2010.To reduce the luck of such serious complication, some preventive measures should be taken before, during, and after implant placement in the anterior part of the mandible, among such measures are the awareness of the regional arterial anatomy, proper treatment planning through radiographic and clinical evaluation of the osseous morphology, and the right angulation and length of the selected implant and finally the skill of the surgeon Kalpidis Setayesh , 2004.Dental CT is a valuable tool for the assessment of jaw bone anatomy and can easily demonstrate the occurrence, position, diameter and crinkle of the lingual vascular supplys of the mandible for this, a CT examination should routinely be performed before any surgical procedure to the anterior region of the mandible to verify the presence of the mandibular lingual vascular canal MLVC and to evaluate the lingual cortical bone thickness and density to avoid perforations and the life lumbering bleeding Scaravilli MS, et al 2009 Naitoh et al. 2010.Distribution of the implants in edentulous jawsIdeal implant distribution and placement is critical in order to secure the optimal mechanical and esthetic outcome of the definitive restorations as well as enabling the patients to maintain proper hygiene. The placement of the implants in the inter-proximal positions may cause problems from an aesthetic, mechanical and hygiene perspective Jivarj S., 2006. Also, the antero-posterior distribution of the implants should allow equal distribution of load over a wide area with minimal cantilever length Adell R et al. 1990 Palmqvist S et al 1994 Jivarj S., 2006. When multiple implants are placed to retain a prosthetic appliance parallelism between the implants should be secured otherwise the unfavorable off-axis loading will not be avoidable Arfai N.K. Kiat-amnuay S. 2007. In the case of implant and tissue supported overdentures both implant placement and distribution become critical where the Implants have to be placed so that when a bar is constructed it has a straight line connection between the implants and does not encroach on the palatal/lingual denture bearing area. The distribution of implants should also be in the way so that adequate space is available for the clip Jivarj S., 2006. When more force from the opponent occlusion- on the implants are anticipated more implants should be placed to share the load Jivarj S., 2006.Treatment planningUntil recently the main concern was directed to the surg ical aspect of implant placement Ganz S.D, 2001. The implants were planned to be placed where the bone is found Kopp et al 2003. The esthetic and functional outcome of the final prosthesis was not much considered Ganz S.D, 2001. The new concept of prosthetically driven treatment planning and implant placement requires careful evaluation of the surgical site. In addition, it must relate the 3-D location of the future prosthetic restoration to the optimal 3-D implant position. This position must be discussed and agreed on between the restorative dentist and the dental surgeon Garber DA Belser UC, 1995, Kopp et al 2003 Park et al. 2009.In the early days dentists who were believing in this concept prosthetic driven were mostly hooklike on conventional radiography, wax-up prostheses and/or surgical templates made on the hard stony surfaces of the study casts, and to overcome the problem of transferring the plan to the operative site, customized radiographic and surgical templates have become an integral part of treatment (Becker CM Kaiser DA. 2000, Almog DM et al.2001. Very soon later, it was found that the hard surface of casts is not equal to the soft tissue surface of the oral cavity, and this method may not be as accurate as necessary for treatment purposes. Additionally, it was established that templates fabricated on the study cast without knowledge of the exact anatomy below the surface cannot be considered reliable Lal K. et al. 2006 and Widmann G Bale JR 2006.The traditionalistic tools for the treatment planning of dental implants include detailed clinical examination, panoramic, cephalometric and peri-apical x-ray films, diagnostic wax-up and articulated study models. Other diagnostic aids may include photography and ridge chromosome mapping technique for the assessment of the implant bone sites. Advanced diagnostic tools such as tomography, digital radiography, and CT scan film allow for a more accurate pre-surgical evaluation sites Traxler M. 1992 , Tyndall D. A. et al. 2000, Flanagan D. 2001, Ganz S.D,2001, Perez A.M. et al 2005, Guerrero M. E. 2006, subgenus Chen Lung-Cheng 2008, Loubele M. et al 2008.Study modelsAccurately mounted casts are critical in assessing prosthetic and inter-occlusal space limitations. Spatial constraints must be considered as a matter of practicality Jivraj S et al 2006. Study casts are also valuable tool to evaluate occlusion Hayasaki et al. 2005 and to help in the treatment planning through diagnostic wax- up Katsoulis J. et al. 2008. Moreover, radiographic and surgical templates can be constructed out of such study models Lal K.et al. 2006 Katsoulis J. et al. 2008 Rubio-Serrano M. et al 2008.Bone lookNo doubt that the direct measurement DM of the ridge size is the most accurate diagnostic tool. However, treatment planning especially in the braggart(a) cases calls for collecting info before surgery. This saves time and money, avoids the unexpected complicated surgeries like harvesting bone for ridge augmentation and increases the predictability of the treatment. When ridge mapping RM is compared to direct measurement DM of the ridge size and to Linear tomography LT cone beam computerized tomography CBCT ridge mapping RM seems to be the most reliable pre- operative clinical method to determine the ridge size Perez L.A. 2005 Chen L.C. 2008., linear tomography is reported to underestimate the ridge size Perez L.A. 2005 while cone beam computerized tomography is reported to overestimate the ridge measurements Chen L.C. 2008.However, ridge mapping is not only an invasive procedure but also a difficult to use in the cases of shallow labial and/or lingual vestibules. Additionally, in ridge mapping the actual position of the inferior alveolar nerve cannot be verified Perez L.A. 2005 Chen L.C. 2008.Conventional two dimensional radiographyActually, conventional 2-D radiography panoramic, cephalometric and intraoral views, which is widely used for the treatment planning, has important diagnostic limitations, such as magnification and distortion, lay errors and position artifacts Tyndall D.A. Brooks S.L. 2000 White SC et al, 2001. Moreover, these 2-D radiographs do not show lingual anatomy or provide complete three dimensional (3-D) information about the dental arch Nikzad and Azari. 2008 . These limitations make the 2-d radiography is less than optimal tool for the diagnosis and treatment planning of dental implants where according to recommendations provided by The American Academy of Oral and Maxillofacial Radiology (AAMOR), The aim of the surgical dental implant treatment planning is to place the optimum number and size of implants to secure the best prosthetic outcome. This can be achieved only if a thorough knowledge of the patients bony anatomy in 3- dimensions is provided in the radiographic examination . comely treatment planning requires that the clinician evaluate the suitability of the remaining bone for placement of implants. The clinici an must determine if there is enough height, density, width of bone, and an appropriate axis of preference for a successful prosthetic outcome Tyndall D.A. Brooks S.L 2000 White SC et al, 2001.CT scanningAlthough Computerized Tomography CT scans have been used in the health check field since 1973 it was not before 1987 when this new technology became available for dental purpose Ganz S.D, 2001. In implant dentistry Computerized Tomography CT scan is one of the most important diagnostic tools which significantly improved the clinicians ability to diagnose and to put accurate treatment plan because it helps in viewing the anatomy and dental related anomalies of the jaws Dula K. et al. 1994 Abrahams JJ Berger SB,1998 AbrahamsJ.J. Hayt M.W.,1999 Lal K. et al. 2006and in the proper choice of implant size and angulation and this in turn helps to avoid injury of critical structures such as the mandibular canal or maxillary sinus Ganz S.D,2001 Scaravilli MS, et al 2009 Naitoh et al. 20 10.Moreover the CT scan allows the visualization of the scanned jaw bone in a series of cross sectional, axile and panoramic views .This makes the planning of implant placement more precise in relation to the bone and future prosthesis especially when the a radiographic template scano-guide is used during scanningLal K.et al. 2006 Rubio-Serrano M. et al 2008 .However CT scan by itself is nothing but series of axial and coronal 2-D images and the clinician needs to integrate such images in his mind to gain the desired information in 3-D Gillespie J.E. Isherwood I.1986.Interactive software programsThe present development of clinical computer applications allows the clinicians to obtain 3-D models to plan virtually real situations Rubio-Serrano M. et al 2008.Interactive computer software is now increasingly used as a tool for implant diagnosis, planning and treatment execution. Firstly, it is used in connection with imaging techniques, such as computerized tomography (CT) or magnetic resonance imaging (MRI) Hassfeld S, Mhling J 2001. Secondly, it is used for the structure of surgical templates carrying the information necessary to transfer that planning to the mouth of the patient. In most of the cases, this procedure is based on stereolithographic models Ewers R . et al 2005 Ganz S.D. 2005 , Schneider D. et al 2009 . on that point are different commercialized soft ware programs are available, such as Implametric, SimPlant Ganz S.D. 2005 Parel SM Triplett RG 2004, Nobel Guide Rocci A et al. 2003, med3D Engelke W Capobianco M. 2005, etc. Most of the programs presentation an axial cut and a panoramic cut with multiple bucco-lingual cuts parasagittal and reformatted 3-D image Parel SM Triplett RG 2004. In the 3D image, bony structures are visualized with the possibility of incorporating other anatomical structures or even soft tissues Schneider D. et al 2009.Bone densityOne of the good tools in the software programs is the ability to evaluate the bone den sity quality during the analysis of CT data. The importance of bone quality density for the success of dental implants is agreed on in the literature Jemt T, Lekholm U 1995 Esposito M et al 1998 Shahlaie et al 2003 Park et al 2008.As suggested by Lindh et al.1996 Site-specific measurements are important, not only for a general prediction of treatment prognosis but also in the evaluation of how long of an interval between first- and second-stage surgical procedure and loading is needed Friberg B et al 1991,1995a 1995b. Moreover, to have accurate preoperative measurements of the bone density helps in avoiding the placement of the implants in the areas of poor quality Norton M.R. and Gamble C. 2001 Shahlaie et al 2003.The strong correlation between the average CT number and the concentration of hydroxyapatite in bone is reported Maki et al 1997, and the quantitative CT in Hounsfield units HU are accepted as a valuable supplement to the inborn bone density classification defined by Lekholm and Zarb 1985. The Hounsfield index is a standardized scale for reporting the reconstructed CT values. It is a measure of the fading coefficient which varies among different tissues, it is based on the density of air (-1000),water (0) and dense bone(1000) Shapurian T. et al. 2006. Misch CE 1993 stated that the bone density measurements using CT scan is more accurate than radiographic assessment. And he classified bones into 5 categories according to density D1 bone had density above 1250 HU D2 = 850-1250 HU D3 = 350-850 HU D4 = 150-350 HU and D5, below150 HU. For this, the use of CT scanning and interactive software programs is considered as a viable and accurate method to measure bone density Norton M.R. and Gamble C. 2001 Shahlaie et al 2003.Recently, efforts in the oral imaging field have focused on developing tools that accurately and automatically measure bone density by measurements of x-ray absorption de Oliveira R. C. G. et al. 2008. Thanks to such efforts, now the CT images in DICOM Digital Imaging and Communications in Medicine format contain the required data of bone density which enables the different software programs can measure it Norton M.R. and Gamble C. 2001 Park et al 2008.Bone graft volumeAccurate evaluation of the 3-D bone volume before surgery is another(prenominal) advantage of the use of soft ware programs in the treatment planning in implant dentistry. The lack of enough bone volume frequently precludes the conventional implant placement. In this condition the bone volume needs to be improved by different augmentation techniques and /or materials Esposito M. et al, 2008.The detailed information about the needed bone volume before surgery is of much help in determining the best donor site Krennmair G. et al 2006 Verdugo F. et al 2009 and can help in estimating the amount and costs of the xenographic bone substitute required for the augmentation surgeryClavero J. Lundgren S. 2003. Moreover, knowing the needed bone volume in ad vance helps in minimizing the period of the surgery and this in turn minimizes the chances of complications and reduces the expenses for the patients Cricchio G. Lundgren S.2003. The computerized tomography CT can produce series of accurate cross sectional images and by the aid of soft ware programs like Simplant Materialise, Leuven, Belgium the 3-D volume of area to be augmented can be calculated Hatano N. et al. 2004 Krennmair G. et al. 2006.Flapless implant surgeryPredictable flapless implant surgery is one of the fruits of the application of modern technology like CT scan, interactive software programs and CAD/CAM fabricated surgical guides Sclar A.G. 2007. Minimal invasive surgery techniques are use to a wide variety of interventions. The main aim is to reduce the costs of the treatment and patient healing time Rubio-Serrano M et al 2008 Valente F. et al 2009.The traditional implant protocol set by Branemark requires a duration of a few months for osseointegration of the endo sseous implants before the connection of definitive dental prostheses Adell R. et al 1981 Branemark PI 1983 Lindquist LW et al 1996. When compared with the surgical phases, implant prosthesis fabrication is relatively time consuming Rodrigues AH et al, 2003.When implants are placed without flap elevation, both the amount of osseointegration and bone height around the implants are significantly greater than in implants placed with flap elevation. This enhancement is most probably due to the preservation of bone vascularization Pennel B.M. et al 1967 Wilderman M.N et al. 1970 Jeong S-M et al 2007. Moreover, the small sized punched mucosa lead to small, clean, closed wounds are known to heal quickly with little scar formation, whereas large open wounds heal easy and with significant scarring Mathes S.J.,2006 Lee D-H et al. 2009.18 D.C. Sabiston and H.K. Lyerly, Textbook of previous termsurgery,next term Saunders, The biological basis of modern surgical practice. Philadelphia (1997) p. 207-20.Recently, the use of flapless surgery for implant placement has become popular. This can be attributed to its numerous advantages that include improved patient comfort and healing, decreased surgical time, and the ability to resume normal hygiene procedures immediately following surgery. However, the flapless approach is only indicated when the surgeon is confident that the underlying osseous anatomy is ideal relative to the planned implant size and its 3-D position in the alveolus. If this is not the case many problems may arise like injury of the unseen vital structures, thermal damage secondary to inadequate irrigation during osteotomy preparation, malposed angle or depth of implant placement, and inability to appropriately contour osseous topography to facilitate restorative procedures Sclar A.G. 2007 Van De Velde T. et al. 2007. For this, the use of the conventional flapless implant placement should be limited to clinicians with advanced clinical experience and good s urgical assessment Sclar A.G. 2007.By no

The American Education System Essay -- Education Reform

To understand how to solve a problem, we must(prenominal) first understand what we are trying to fix. For example, can a carpenter without any medical come repair a heart valve? Of course not, he or she must first obtain the proper reproduction necessary to perform such a complex operation. The same can be said about the American education system. Throughout Americas history parents, educators, and government officials have been debating what changes must be implemented for American children to receive every opportunity possible to gain an education that will prepare them for the future. However, these cries for reform are so demanding that umpteen times the reforms created to please the people are pushed through so fast that consequences are never completely considered. These latest cries for reform came after the annual make known by Program for International Student Assessment (PISA) was released in December 2010 stating that 15-year-old American students ranked average in ma thematics, reading, writing, and science (Duncan, 2010). Average might not be much of an alarm to many however, when companies, such as Microsoft, have to hire software engineers from other countries to fill positions because Americans are unqualified, it brings everything to other level (Guggenheim & Chilcott, 2010). The use of standardized, multi-choice, fill in the bubble tests to hold schools accountable for what is taught within their walls has become detrimental to the education system. Standardized testing is designed for a system of equality for which the school system is not. Teachers and schools cannot be held to the same accountability as other schools when there exists no equality in them in regards to budgets, resources, qualifications of teachers, ... ...earning, to be educated by those of a greater understanding. If children are to have the ability to contribute to society, and be able to succeed in life, a proper education must be made available to them. Not an edu cation of learning how to take tests, but one of knowledge - an education given to them that teaches them how to apply mathematics in their lives, to use the sciences to understand the world around them, and to be able to read and be enlightened by its message. The public school is a menage that students should want to go, hunger to go. It should not be a role of stress or fear due to an upcoming test. It needs to be a place where all have the freedom and opportunity to learn. Standardized tests had their moment in time now the focus needs to be turned to a more(prenominal) in-depth education of understanding how to apply their knowledge to their everyday lives.

Ethnocentrism And Cultural Relativity Essay example -- essays research

It is always troublesome not to understand another culture, especially, in new-made York City where we live in a society that is rapidly changing. The City has increasingly brought people of various cultures, to interact closer with each other. This interaction outhouse be either verifying or negative depending on the level of sensitivity and respect people have for other culture stems. These two types of behaviors ar related to two important concepts known as ethnocentrism and cultural relativity.Ethnocentrism is the attitude of prejudice or mistrust towards outsiders that may exist within a group (in-group) in relation to other (out-group). (Harper-Collin Dictionary of Sociology). Importantly, there are also three levels of ethnocentrism a positive one, a negative one, and an extreme negative one. The positive definition defines ethnocentrism as the point of view that ones own way of life is to be preferred to all others (Herskovits 1973 21). There is nothing harm with such feelings, because it characterizes the way most individuals feel about their own cultures, whether or not they verbalize their feelings (Herskovits 197321). It is this point of view that gives people their sense of people-hood, group identity, and set in history. Ethnocentrism becomes negative when ones own group becomes the center of everything, and all other are scaled and rated with reference to it(Herskovits 197321). It reaches extreme negative sorting when a more powerful group not only i...
