Tourettes Syndrome Essays - Psychiatric Diagnosis, Tourette Syndrome

Tourette's Syndrome What Makes Them Tic? Tourette's syndrome is a neurological disorder, which involves involuntary body movements or Tics. There are two types of Tics, motor/physical and vocal. This paper will cover many aspects of Tourette's syndrome; including the history of the disease, the discovered of the disease, the genetics involved with the disorder, the diagnosis of the disease, and the effects of the disease on families. George Gils de la Tourette's a French doctor and biologist discovered Tourette's syndrome in 1885 (Landau 21). He was observing patients with unexplained repetitive movements and could not find any preexisting condition that would cause these symptoms. After extensive research he concluded that this disorder had not been documented before, so he named it Tourette's syndrome, after himself. Tourettes syndrome is a neurological disorder; it is inherited from a parents dominant gene, causing different symptoms among different family members. It is not known on which chromosome the disease is located. There is a 50% chance that one will pass this trait on to his/her offspring with each pregnancy (Shimberg 64). There is no prenatal testing that can be done before a child is born to determine if the child has the disease. Unlike other genetic disorders or disease Tourette's is not in the blood. Therefore testing will not give any indication of whether or not a child will develop Tourette's. Cases of the disease show males are burden with the disease three to four times more often then females. There is a 15% chance that the disorder will evolve during childhood. Both motor and vocal tics become less frequent with age but unfortunately will never Thursfield 2 disappear. The U.S. Medical Survey estimates that 100,000 people have full blown Tourette's syndrome, and there are up to 300,0000 have minor undiagnosed cases. Tourette's Syndrome causes an individual to lose control of body movement resulting in repetitive actions and verbalizations. These involuntary movements are called tics. There are two kinds of tics, motor/physical and vocal. Motor tics can be simple or complex in appearance. Simple motor tics are abrupt, sudden, and brief movements, occurring in a single or isolated manner. Examples of simple motor tics include eye blinking, head jerking, shoulder shrugging and facial grimacing. Complex tics are distinct, coordinated patterns of sequential movements. Examples of complex tics include such acts as touching the nose, touching other people, smelling objects, jumping, copropraxia (obscene gestures), and echopraxia (mimicking movements preformed by others), head shaking associated with shoulder shrugging, and repetitive kicking of the legs (Shimber 25). Complex physical tics among Tourettes patients are uncommon and only found among a small population. Motor tics usually recur in the same part of the body, and multiple regions of the body can be involved. The expressions of the tics are not necessarily identical from occurrence to occurrence, even within the same body part. Tics often recede from one part of the body and evolve elsewhere. Vocal or phonic tics are caused by air moving through the mouth, nose, or throat. Vocal tics can be subdivided into simple and complex. Simple vocal tics include sounds, groans, grunting, hissing, gurgling, gasping, belching, screaming, snorting, shouting, puffing and other mouth noises. Complex vocal tics consist of uttering words or phrases out of context and coprolalia (vocalizing socially unacceptable words). Thursfield 3 There are several associated behaviors in addition to the tics that Tourettes patients suffer from. One of the most common disorders is Attention Deficit Disorder with or without Hyperactivity (ADD or ADHD). Symptoms of ADD may include: difficulty with concentration, falling to finish what is started, not listening, and often acting before thinking (Shimberg 74). Tourettes patients may also suffer from obsession and or exhibit sleeping disorders. Obsession consists of repetitive unwanted or bothersome thoughts. Those patients that suffer from sleeping disorders may frequently walk or talk in his/her sleep. A typical case of Tourettes syndrome is hard to define because the symptoms fall within a wild spectrum from mild to sever. Observing symptoms and evaluating one who exhibits characteristics of Tourettes syndrome is the only way to make a diagnosis. Since, this is a neurological disorder there are no x rays, scans, blood or neurological test that can be preformed to determine if this is the condition that

Islamic Fundamentalism Replaces Communism Essay

Islamic Fundamentalism Replaces Communism Essay Free Online Research Papers Islamic fundamentalism has replaced communism as the enemy of the day. But despite the growing perception in this country that Islamic fundamentalism poses a threat to the United States, many Americans have only a minimal understanding of who Islamic fundamentalists are, what they believe and why their ranks continue to grow. Misconceptions are common, with one-dimensional views of Islamic fundamentalists as violent extremists prevailing over more nuanced understandings of a movement that is complex and diverse. Context, say scholars, is everything, and the political and economic climate that pertains in many Muslim countries, particularly in the Middle East, fuels Islamist movements that go beyond respect and reverence for the Islamic religion to adopt Islam as a political strategy or that refer to Islamic principles in calling for social and political reforms. These â€Å"Islamist† movements have developed increasing popular support as other efforts at economic and political reform in Muslim societies have failed. Woman Half the Man Islamic sacred law, the Shari`a, has been regarded by Muslims as a perfect, divinely ordained religious-ethical-legal system. The Shari`a relates Muslims to Gods purposes by providing comprehensive directives in the two spheres of human activity: those actions that relate humanity to God, and those that relate humans to fellow humans. The former actions are categorized as `ibadat (literally, acts of honoring God, technically, God-human relationships) and the latter is known as mu`amalat (literally, transactions, technically, interhuman relationships). Whereas the God-human relations have remained more or less immutable in the Shari`a, the area of interhuman relationships has demanded a rethinking and reinterpretation of the normative sources like the Quran and the Sunna (Tradition) to deduce new directives under changed social conditions. There are problems connected with the way normative sources are retrieved and interpreted by Muslim jurists which have hampered the necessary progr ess towards one particular area in the interhuman relationships, namely, the personal status of Muslim women. The juridical deliberations in the exclusively male-oriented traditional centers of Islamic learning, the madrasa, have disregarded female voices in the emerging discourse connected with womens issues and human rights. The redefinition of the status of a Muslim woman in modern society is one of the major issues that confront Muslims. But such a redefinition is dependent upon Muslim womens participation in the legal- ethical deliberations concerning matters whose situational aspects can be determined only by women themselves. Without their participation in legal-ethical deliberations, womens rights will always depend on a representational discourse conducted by male jurists who, in spite of their good intentions, treats the subject as absent and hence, lacking the necessary qualification to determine her rights in a patriarchal society. Osama Bin Laden In todays society, we still see the Islamic religion affect the world around us. An Islam militant named Osama bin Laden has been using this religion to get people on his side and attack other countries for the good of Islam. He thinks more killings will get his people closer to paradise. This militant and his terrorist group has told US that they are declaring a holy war on US; thus, the United States struck back with missiles to destroy some of their weapons and arsenal. The Islamic religion has affected many things in this world from the past and present, which proves this is a popular religion in many cultures.

Strategic Planning Assignment Example | Topics and Well Written Essays - 1500 words

Strategic Planning - Assignment Example Irish colleges have changed their age old stance of focusing only on domestic students. Globalization of educational system has forced Irish colleges to think beyond domestic boundaries in order to attract international students. Higher educational system of Ireland has already experienced a boom due to rapid internationalization during the period of 1995 to 2007, which is known as ‘Celtic Tiger years’. In that era, China was an important source for student immigration in Irish colleges but supply of international student has reduced after the recession which has painstakingly reduced industrial output of Irish economy. As a result of industrial slowdown in Ireland, private parties have reduced higher education funding for universities and colleges (ICEF Monitor, 2012). In such context, Irish government has taken initiative known as â€Å"Education in Ireland† in order to market the existing education programme in Irish universities and colleges in international m arkets such as Argentina, Brazil, China, India, USA etc. Irish Government has planned to implement recommendations made by Hunt Report (2011) in order to attract international students... Hence, due to involvement of customer perception variables, Irish colleges need to build their brand among international students in order to convince them that Irish colleges are capable of delivering quality education. The researcher in the study is head of Strategic Planning Division of Irish owned and managed college and board of the college has asked the researcher to prepare strategic recommendation for the college on how to increase its penetration in Argentine educational sector and simultaneously increase its Argentine student base. Hence, following sections of the study will try to throw some light on issues like macro environmental analysis of Argentina, analysis of educational sector of Argentina, challenges regarding cultural and managerial practices in both countries, identifying strategic options etc. Part 1- Research Macro-environment To understand a country, one must take a step forward to analyze macro-environment of the country; hence the researcher will analyze ma cro-environment of Argentina in terms of PESTLE analysis. Political Argentina can be called as pariah state due to its unstable political environment which is complemented with nepotism, corruption and cronyism. Gabriel Torres (who is senior analyst in Moody's) has stated that, â€Å"Argentina's inability to solve its political differences is a problem, contentious politics make the country less able to cope with the impact of economic shocks† (Mercopress, 2009). Although political instability in the country has hampered the economic growth in the country but Argentine government has taken initiatives during 1990s to reform the educational sector in order to increase privatization and internationalization of higher education sector. Educational reform

Summarize two articles Essay Example | Topics and Well Written Essays - 250 words

Summarize two articles - Essay Example Bankrupt companies in Japan seem to find a way out of their debts by inviting foreign enterprises to bail them out. One example is Elpida Memory which agreed to be taken over by the American Company, Micron Technology for $760 million with the expectation that $1.8 billion be made to pay for Elpida’s debts in banks and other secured creditors at 70% of what they are owed. Unsecured creditors of Elpida, on the other hand only get 20-30% of what they are owed. This has caused much uproar amongst bondholders who complain that the Micron offer was way below the value of the Elpida company, which they claim is valued at $3.8 billion. Hence, they have resorted to seeking other sponsors to take over. In the past, Japan would not have allowed such battle to happen since investors rolled over funds while a restructuring was forced upon them. The government would force the takeover of a bankrupt company, causing negative outcomes for the company itself and its employees, and being a bur den to the economy. Nowadays, bankruptcy is a real option due to more openness to foreign take-overs rescuing failed Japanese

Evaluate the application of revenue management practice in the hotel Essay

Evaluate the application of revenue management practice in the hotel industry and discuss its impact on customers in the hotel industry; - Essay Example dification in the general handling of revenue management, inventory allocation, pricing strategy, use of information and channel management as concerns to revenue management tend to redefine the field. Similarly to how detailed past analysis might have a representation of the best pricing practice during the 1990s, apparently, the stock market-impacted algorithms exist in the cutting edge of modern pricing thought. Comparably, the highlighting on occupancy or average day to day rate, which might have dominion over revenue managers’ outlook over two decades ago has led to the dominance of revenue per available room i.e. RevPAR. Instances like this abound hence this article will endeavor to share all of the revenue management expertise with readers, in a series examining the modern revenue management’s best practices (Kimberley, Trevor & Juston 2008, p.12). Pricing tends to a feature of revenue management, which features a number of intriguing, as well as innovative developments recently. Whereas pricing has continues to be a significant driver having an effect on both occupancy, along with RevPAR, in the present environment surrounded by exceptional price transparency, rates have taken an even bigger role. Ascertaining the optimal rate to give to a potential customer tends to be one of the most significant concepts of revenue management. The basic fact that the appropriate rate- one that achieves the balance between replicating enough demand in maximizing occupancy, while at the same time, not deserting money on the table within the form of low down ADR turns out to be the key to a profitable revenue management strategy causing pricing perhaps the most significant concept of revenue management. Then how is a hotel capable of determining what the best rate has to be any time? In the past, this would center on historical analysis, while , at the same time, computed by the application of a discount to a fixed rack rate. In this case, there is no achievement of

Non-visual Motion Tracking

Non-visual Motion Tracking Additionally, (Taylor et al. 2010) demonstrated that the OSSCA method, which employs a combined use of OCST, SCoRE, and SARA techniques to process marker data and allows the estimation of joint parameters from kinematic data alone, without the necessity to use generic anatomical relationship assumptions, returns more reliable, repeatable and reproducible results than a standard generic regression approach. Although the accuracy of the data acquired by means of optical motion capture systems is very high in the controlled environment of the lab, the ambulatory use of this type of equipment is cumbersome and presents significant limitations which can not only compromise the precision of the acquired data, e.g. dependency on line-of-sight, limited range and latency of data (Schepers et al. 2010), but also the practicability of the acquisition itself, e.g. necessity of power source, set-up time, outdoor calibration of the system. Non-visual motion tracking Non-visual motion tracking is a sensor based technique, which can be carried out, amongst others, with acoustic, magnetic, or inertial sensors, or with a combination of these methods. Ultrasound based acoustic systems, e.g. the Bat system (Ward et al. 1997), Vallidis (Hazas and Ward 2002), the Cricket location system (Priyantha et al. 2000) and WearTrack (Foxlin and Harrington 2000), are capable of tracking the locations of pulse emitting beckons by using the time-of-flight information of audio signals. This type of motion tracking system is wireless, however, as with visual motion tracking, occlusion of the signal emitter poses a significant limitation. In contrast, magnetic systems, e.g. MotionStar ® (Ascension Technology), are capable of estimating their position and orientation within the global coordinate system, by using information from the local magnetic environment, and are, therefore, not constricted by line-of-sight. However, these systems are very sensitive to ferromagnetic interferences. Inertial motion capture systems, e.g. Moven (Xsens Technologies) and Alert (Verhaert), employ the use of accelerometer and gyroscopes to measure inclination angles. These systems are highly accurate, however, sensitive to vibration and subject to integration drift over time. In fact, throughout the past decade, the use of inertial sensors has gained increased popularity within researchers (Foxlin 1996; Roetenberg et al. 2007a; Roetenberg et al. 2005; Roetenberg et al. 2009; Roetenberg et al. 2003; Roetenberg et al. 2007b; Roetenberg and Veltink 2005), as well as general population. Many people schedule their daily activity based on the data presented by certain applications on their smartphones (e.g. Health app, Argus, MyFitnessPal), their smartwatches (e.g. Sony, LG, AppleWatch, Fitbit Surge) or pedometers and wristbands (e.g. Fitbit Flex, Garmin vivofit, Polar Loop, Jawbone). However, in the field of research, there is a need for more complex systems, which can provide more comprehensive information, of a larger variety. For this purpose, hybrid systems, combine the use of different techniques to compensate for the shortcomings of individual systems. Such hybrid systems are represented by acoustic-inertial systems (Vlasic et al. 2007; Ward et al. 2005), e.g. Constellationà ¢Ã¢â‚¬Å¾Ã‚ ¢ (Foxlin et al. 1998), optical-inertial systems, e.g. Hy-Birdà ¢Ã¢â‚¬Å¾Ã‚ ¢ (Ascension Technology) and inertial-magnetic systems, e.g. MERG sensors (Bachmann 2000), MTw development kit (Xsens Technologies), MVN Biomech and MVN Awinda (Xsens Technologies). Combined inertial and magnetic sensing is currently one of the more popular choices in this area of study and will be discussed at length in the following paragraphs. The light weight, wireless and cheap, inertial sensors equipped with accelerometers, gyroscopes and magnetometers enable, when positioned on the human body, the computation of angular orientation of the anatomical segments to which they are attached to (Bellusci et al. 2013; Roetenberg et al. 2003). The on-board gyroscopes measure angular velocity, based on the principle of angular momentum, according to the following fundamental equation: (1) Where: à Ã¢â‚¬Å¾ torque on the gyroscope; L angular momentum; I moment of inertia; à Ã¢â‚¬ ° angular velocity; ÃŽÂ ± angular acceleration. The most commonly used gyroscopes for human motion studies are piezo-electric, capable of detecting vibration of mass. When an object vibrates while rotating, it is subject to the Coriolis Effect. This causes a second vibration to occur orthogonally to the initial vibration direction. The rate of turn can be calculated from this latter vibration. According to the following equations: (2) Where: m mass; à ¡Ã‚ ´Ã‚   momentary speed of the mass with reference to the moving object to which it is attached. The resulting gyroscope signals are then defined as being the sum of angular velocity à Ã¢â‚¬ °t, offset due to temperature of gyroscope bt, and white noise à ¡Ã‚ ´Ã‚  G,t (Eq. 3). (3) The gyroscope output is very accurate, however, it is subject to errors and drift caused by integration of the signal over time, and the gyroscope temperature which can produce small offset errors, leading to large integration errors when calculating orientation. The use of compensatory estimation algorithms, such as Kalman filters can reduce the inherent errors in the gyroscope output signal (Roetenberg et al. 2003). Kalman filters are mathematical algorithms used to efficiently minimize the mean of the squared error of a system output (Welch and Bishop 1995). Kalman filters are particularly useful for combining parameters of different measurement systems so that the advantages of one compensates for the weakness of the other, e.g. accelerometers are often used in conjunction with gyroscopes, in order to compensate for inclination drifts in the gyroscope signal. The accelerometers measure the gravitational acceleration g and the vector sum of acceleration a. The output accelerometer signals are defined as the sum of acceleration at, gravity gt and white noise à ¡Ã‚ ´Ã‚  A,t. (4) The inclination information provided by gt can be used to correct the orientation drifts of the gyroscope (Roetenberg et al. 2003). A further common example of Kalman filtering, is using magnetometer readings to correct for the gyroscopes vertical axis drifts (Roetenberg et al. 2003). Magnetometers have the ability to detect local magnetic north and adjust heading direction. The principles by which the magnetometers work are described by following equation: (5) Where: ym,t magnetic signals; mt earth magnetic field vector; dt disturbance vector; vm,t -white noise. In real life measuring conditions the distribution of the magnetic field is often more complex and other parameters, such as changes in magnetic flux and the magnetic inclination angle, which can affect the magnitude of the magnetic disturbance, should be taken in consideration. The major limitations of using inertial and magnetic sensing for motion tracking are represented by the following factors: Ferromagnetic interferences can distort the local magnetic field and affect the measurements for the orientation about the vertical axis (Roetenberg et al. 2003). The velocity and type of movement performed and the geometry of the body segment to which the sensor is applied can affect the accuracy of the measurements (Roetenberg et al. 2005); Distances between body segments cannot be assessed by means of numerical integration (Roetenberg and Veltink 2005); Previous studies in which this type of equipment was used report a high accuracy of the output data (Cutti et al. 2010; Ferrari et al. 2010a; Seel et al. 2014), however, the limitations in using this motion capture system are far from being overcome. The most important and challenging aspect of the study is to use the acquired information in a biomechanically meaningful manner, e.g. the parameters declared as joint angles, need to be as anatomically accurate as possible, for this purpose assuming the joint angles can be calculated as the angles of movement between two anatomical segments is not enough, a more complex mathematical model needs to be developed in order to address the biomechanical characteristics of the studied joint. There are a variety of protocols and algorithms available for post processing of sensor data stemming from human motion studies. A common approach for solving a human kinematics problem is to compare the human body to a robot manipulator. Similarly to a robot manipulator, which forms a kinematic chain from links interconnected by joints, the human body can be considered a kinematic chain formed of anatomical segments connected by articulations. In theory, this is a very efficient manner to solve a biomechanical problem. Cutti et al., for example, use the Danavit-Hartenberg convention of robotics in their Outwalk protocol, which states that a kinematic chain with n joints will have n+1 links (Fig 2.4). To solve the kinematics, a coordinate system is rigidly attached to each link. In this case, when joint is actuated, the adjacent and its attached coordinate frame perform a motion. Whichever motion is performed by the kinematic chain, the coordinates of each point on are constant when expressed in the coordinate frame (Zatsiorsky 1998). The Danavit-Hartenberg convention has two conditions which need to be satisfied in order for the kinematic solution to be effective. The variables of a joint (e.g. rotation angles) are defined by the two coordinate systems of the links adjacent to the joint. So, for example, the coordinates of the frame are expressed in the frame. Firstly, the orthonormality of the frames needs to be established, meaning needs to be perpendicular to . Secondly, the projection of in the frame ought to intersect . Comparing the human body to a robotics model is a good starting point. However, using the, frequently associated, strap-down integration method when measuring human kinematics with sensing units poses a very important limitation (Seel et al. 2014). The strap-down-integration method is based on using sensing units securely fixed to the even surfaces of robotic elements. However, there is a significant difference between a robotic setup and an anatomical system. Firstly, aligning the sensor to an anatomical location, such that one axes of the sensor coordinate system coincides exactly with an axis of the anatomical joint, is nearly impossible (Seel et al. 2014). This issue has been addressed in different manners by researchers so far. In the Outwalk protocol, Cutti and Ferrari et al. define as many coordinate frames for each link as the joints they form. Each anatomical segment has, therefore, a distal and a proximal coordinate frame. The joint variables are defined by the distal coordinate frame of one segment and the proximal coordinate frame of its adjacent segment. Another issue that needs to be addressed, when discussing a human biomechanical model, is an almost certain misalignment of the thigh axis with the segments coordinate system. Some studies completely ignore the misalignment between the anatomical and the sensor axes (Seel et al. 2014). In the Outwalk protocol this problem is solved by expressing the flexion-extension axis of the knee in the coordinate system of the distal femur and defining the other revolution axes of the coordinate frame as being orthogonal with respect to the new axis. This is another promising approach, however, in order for this method to be effective, the knee flexion-extension axis needs to be accurately identified. In the case of hinge joints, such as the simplified model of a knee joint, it is possible to calculate data from inertial sensors attached to both ends of the joint. However, this resulting data still needs to be translated into joint related coordinate systems and although, it is impossible to determine the initial position of the sensors on the anatomical segment, there is a possibility to determine the direction of the joint axes, by using different approaches to identify a functional movement axis from a set of dynamic motion data (Cutti et al. 2010; Ferrari et al. 2010a; Seel et al. 2014). In their protocol Cutti and Ferrari et al. use Woltrings mathematical solution for determining the finite helical axis (reviewed in (Zatsiorsky 1998)) to identify the knee flexion-extension axis. Woltrings solution appears to be fitting at least for most motion capture systems (Seel et al. 2014). However, the sensing units used in our study cannot measure translation. This would pose a big problem and could potentially result in substantial errors. In order for the outcome of the study to be successful, it needs to satisfy a set of conditions: (1) it is very important that the resulting post-processed sensor data is biomechanically meaningful to the musculoskeletal system; (2) data acquisition needs to be user friendly, rapid and easy to complete; (2) sensor mounting is not allowed to restrict the participants movement in any manner; (3) the resulting data needs to relate to true anatomical joint angles; and (4) the resulting information needs to be comparable to the reference system (Vicon). Seel et al. offer a solution based on rotational angle estimates alone, which is not only more simple from a data acquisition and processing point of view, but also functions on principles similar to SARA and SCoRE. In the protocol proposed by Seel et al. the knee is assumed to be a simple hinge, with one sensor attached to each segment forming the joint. In order to compensate for the lack of information concerning the initial position of the sensors on the anatomical segments, the unit length direction vectors and the orientations of the two segments attached to the hinge joint (Fig 2.6) are estimated as described below. The Seel et al. solution only employs the use of what is considered to be raw accelerometer and gyroscope output data from the two sensors, the thigh sensor and the shank sensor. In reality, any output data produced by the Xsens sensors, used in Seel et al.s study and the current study, is pre-processed in real-time by the on-board Kalman filter. For the purpose of the summary of the following protocol, all data indexed with 1 refers to thigh sensor data and data derived there from, and all data indexed with 2 refers to shank data and data derived there from. Firstly, the unit length direction vectors of the flexion-extension axis of the knee , are identified in the local coordinates of the sensors, by using an optimisation algorithm to compute the values of . Where the spherical coordinates for are: (6) (7) With the following sum of squared errors: ; (8) A search function is then used to find which satisfy the following condition: (9) Where: angular rates recorded by the thigh and shank sensor, respectively, with the sample period: constant; Euclidean norm. The acceleration measured by each sensor is the sum of the acceleration due to movement around the joint centre and the acceleration due to the rotation of the sensor around the joint centre. In order to estimate the knee joint position expressed in the local coordinate systems of the sensors, the amounts by which are shifted in order to obtain the acceleration of the joint centre, are estimated first. Two arbitrary points along the axes are estimated using a Gauss-Newton optimization algorithm. These points are shifted as close as possible to the sensor origin by applying: (10) (11) The radial and tangential acceleration due to the rotation of the sensor around the joint centre is computed: ; i=1,2 (12) Where: are time derivatives for angular rate and (13) The following sum of squared errors is calculated: ; (14) A search function is used to find which satisfy the following constrain: (15) The knee flexion/extension angle based on the gyroscope information is calculated with the following equation: (16) The measured accelerations are shifted onto the joint axes by applying the following: (17) (18) Where, represent the same quantity in the two different local coordinate systems, which rotate with respect to each other around the flexion axis. The flexion/extension angle calculated according to acceleration data can be defined as the angle between the projections of . (19) Where, and are pairs of joint plane axes, defined by: ; The knee flexion/extension angle defined by fusing the accelerometer and gyro data is defined by: (20) Where: knee flexion extension angle calculated according to accelerometer data at time t; knee flexion extension angle calculated according to gyroscope data at time t; the weight of the accelerometer data. By using the most effective methods presented in the literature review, the current study will attempt to validate the inertial sensor protocol proposed by Seel et. al 2014 against a OSSCA method and to compare laboratory and non-laboratory based inertial motion capture.

Niccolo Machiavelli :: essays research papers

Niccolo Machiavelli was born on May 3, 1469, in Florence, Italy. He eventually became a man who lived his life for politics and patriotism. Right now, however, he is associated with corrupt, totalitarian government. The reason for this is a small pamphlet he wrote called The Prince to gain influence with the ruling Medici family in Florence. The political genius of Niccolo Machiavelli was overshadowed by the reputation that was unfairly given to him because of a misunderstanding of his views on politics. Machiavelli's life was very interesting. He lived a nondescript childhood in Florence, and his main political experience in his youth was watching Savanarola from afar. Soon after Savanarola was executed, Machiavelli entered the Florentine government as a secretary. His position quickly rose, however, and was soon engaging in diplomatic missions. He met many of the important politicians of the day, such as the Pope and the King of France, but none had more impact on him than a prince of the Papal States, Cesare Borgia. Borgia was a cunning, cruel man, very much like the one portrayed in The Prince. Machiavelli did not truly like Borgia's policies, but he thought that with a ruler like Borgia the Florentines could unite Italy, which was Machiavelli's goal throughout his life. Unfortunately for Machiavelli, he was dismissed from office when the Medici came to rule Florence and the Republic was overthrown. The lack of a job forced him to switch to writing about politics instead of being active. His diplomatic missions were his last official government positions. When Machiavelli lost his office, he desperately wanted to return to politics. He tried to gain the favor of the Medici by writing a book of what he thought were the Medici's goals and dedicating it to them. And so The Prince was written for that purpose. Unfortunately, the Medici didn't agree with what the book said, so he was out of a job. But when the public saw the book, they were outraged. The people wondered how cruel a man could be to think evil thoughts like the ones in The Prince, and this would come back to haunt him when he was alive and dead. However, if the people wanted to know what Machiavelli really stood for, they should have read his "Discourses on Livy", which explain his full political philosophy. But not enough people had and have, and so the legacy of The Prince continues to define Machiavelli to the general public.
