Dating Violence among Teenagers Term Paper Example | Topics and Well Written Essays - 750 words

Dating Violence among Teenagers - Term Paper Example I have chosen two empirical studies to help me understand this phenomenon and try to bring about changes that would beneficial to them. In a study conducted by (Champion H. 2008) on different risk and protective factors involving individual behavior related to dating violence and victimization among teenagers, many interesting facts were highlighted. To analyze the facts on the important issue of dating violence among teenagers, surveys were conducted for 2000 students belonging to the North Carolina High School. On examining the level of violence on the dating issue from a gender point of view, it was found that females were more at risk than the males. Results showed that when comparing the females to males, females experienced a higher level of perpetration (8.8%) than the males who had only 4.0% risk. (Champion H. 2008) Findings on the issue of victimization showed that while females were at a higher risk with 7.2%, male victimization was only 5.0%. (Champion H. 2008) The results from the study proved that there is a higher incidence of female perpetration and victimization and they were more at risk when compar ed to males. Some of the common causes observed in the study were drunken driving, tobacco and alcohol abuse, drug abuse. When comparing the different multivariate models associated with violence in dating, men were less likely to be victimized than women. However, there could be few exceptions. The findings also showed that the role of community should be enhanced to counter this problem by conducting various activities within the community and making the youth more responsible in the way they approach life. In a study conducted by (Miller S. 2009) the method used to gauge dating violence among teenagers was directed towards interviewing parents and peers for predictors of violence and perpetration during physical dating. The participants chosen

The Wars of the roses were caused by weak kingship.In the context of Coursework

The Wars of the roses were caused by weak kingship.In the context of the period c1377-1487,how far does this statement explain - Coursework Example Although this paper covers the period of 1377-1487, a special attention will be paid to the events of 1450-71, even though the other time spans of the said period will be duly analysed as the case may be. To achieve this goal, I have decided to divide my paper into four sections, three of which have their sub-sections. In the first section, I will deal with the influence of personal qualities of Henry VI on the political events which led to the Wars of the Roses, as well as on disintegration of central authority in the preceding years. The comparison between Henry VI and the other kings of the period will be provided with a view to determining the impact of royal personality on political processes of the period. In the second section, I aim to discuss the role of political and blood feuding between various noble houses as exacerbating instability and general political crisis both in the beginning of the Wars and during their immediate course. I will look both at the main conflict cen tred on the leaders of Yorkist and Lancastrian factions and at the different local feuds that led to the situation steadily deteriorating. The third section deals with the impact of the external factors, focussing on the loss of Lancastrian France and the discontents it generated. The economic crisis and the dynastic factor are briefly analysed in section 4. At the end of the essay some conclusions on the interrelation between the weakening of royal power under Henry VI and the other causes of the Wars of the Roses are provided. I also include the detailed bibliography of the subject under consideration after the Works Cited that would provide additional support to the argument that this paper defends. THE WEAKNESS OF THE KING Academics’ views on the personal qualities of Henry VI. There is no doubt that the reign of Henry VI was marked by progressive weakening of royal prestige and authority, which eventually led to the major strife among the nobles of the realm. For instanc e, Wolffe argues that Henry VI’ character was marked by â€Å"perverse wilfulness† and that his â€Å"wilful incompetence and untrustworthiness† made him completely unreliable in the affairs of government (Wolffe, â€Å"The Personal Rule† 44). McFarlane remarks that the â€Å"inanity† of Henry VI in the years of his personal rule was characteristic of an infantile person incapable of independent reasoning (McFarlane, â€Å"Nobility† 284). In addition, Carpenter finds that the period of personal rule of Henry VI was characterised by â€Å"the lack of the royal will at the heart of it† (88). At the same time, Griffiths observes that Henry VI was by nature â€Å"a well-intentioned man†, but at the same time he agrees that the king was â€Å"over-merciful and compassionate to those at fault, yet fearfully suspicious of those who were rumoured to be doing him personal harm (Griffiths, â€Å"The Reign of Henry VI† 253). Howev er, to prove or disprove such claims, one has to look

This notwithstanding, it is a good thing that you recognized that there will be different stages of decision making and thus the need to diversify your decision making tools. Â  Hello John, it is great to read about how you identify instances where each of the decision making tools is relevant and the advantages and limitations that come with each of them. I have always believed that companies have failed in the implementation of decision making on investments because they refuse to weigh out their options very well. This is because in most cases, the companies overly rely on the advantage that a particular decision making tool would bring without looking at possible disadvantages. But as stressed by quote (year), it is very important that at every point in time, decision making will be made around whether the company’s priority is with time value of money or with the quantitative outcomes from investment. Regarding your current project, I believe it is a very good thing that you decided to select only two methods which are discounted payback and NPV. With such specification, you will be able to stay focused on the monitoring of your

Learning Log - Essay Example The situation makes it difficult for the visiting Chinese to enjoy. This idea influenced the owners of this restaurant to create an opportunity to the Chinese in heart of London. Many clients visiting the restaurant have remarked that the restaurant has enabled them to acquire the best in a foreign land. The restaurant respects and promotes Chinese culture. Reception of clients who visit this restaurant would attest to the above fact. The restaurant location is heart English land where one would expect to meet the English culture. However, the uniqueness of the restaurant stem up from the fact that it roots for the native culture of the Chinese. This is the best that a person would imagine especially when an individual has been dreaming of experience the native culture. Language is an aspect of culture, which influences all other activities in the society. The restaurants prefer addressing its Chinese visitors in Chinese language and other visitors in the most appropriate language (T ouro). The idea is to protect the business from failing to cater for the interest of the society. Serving the needs of Chinese people as well as the needs of the people who embraces the Chinese culture is the sole objective of the restaurant. This objective is evident through the long-term service that the restaurant has offered to the society since its inception in 1890s (Chongqing Expat Club, 2008:3). ... Today the practices in the restaurant indicate respect for the Chinese culture. Human culture differs owing to the fact that people live in various geographical regions. The practices observed in London by Londoners are much different from practices of Chinese in Beijing. How the fabric that formed the foundation of the restaurant anticipated to carry the practices alive. My placement at Chongqing San Jia Xiang restaurant exposed me to two events; first, exercises my communication skills in an international environment second to retain stress. The restaurant offers services to international guest visiting or residing in London. Communication is a crucial tool in the hospitality industry that dictates the number clients. Clients visiting various recreational facilities are keen to reception in their new environment. The restaurant offers a warm reception to people (Touro). Exposure to new environment offers an opportunity for learning new approaches. I was not an exception to this exe rcise. I had to receive clients, listen to their demands and respond. The experience was good because the management managed to influence my reaction whenever I misunderstood the clients. People have different abilities yet they need services. It means I had to develop skills of response as well as skills of controlling my temper whenever the demands were out of my taste. The organisation concern promotes an environment where a person could be able to learn. Individual’s presentation influences ones ability to handle clients. The restaurant management and staff created an environment, which encourages an individual to be presentable. The restaurant holds routine departmental meetings, which aims at analysing and attending to problems of the workers. The

History - Essay Example The Republican sense of democratic governance depends solely on the concept of liberation, and it is non-existent in the English constitution. He contests monarchy and hereditary succession and points out that the English monarchy in itself had a long history of election and usurpation which holds against the Divine Rights theory. The latter half of 18th Century America has witnessed intolerable tyranny from the part of the royal representatives in its colonies, and the consensus to overpower the British rule and declare liberty for America is represented and promoted by the ‘Common Sense’. It asserts the basic right of American people for â€Å"life, liberty and the pursuit of property†. Paine points out in the conclusion that American independence is imminent due to certain unavoidable factors like the differences of priorities in British and American mindset regarding foreign affairs. The kind of mediation America wishes from other nations is made impossible if they remain under the rule of Britain, the association with nations like France and Spain will not take place because of their bad relationship with Britain, American rebellion on many counts against Britain is a reality and this makes things worse if British rule continues and there is general discontent and protest regarding British cruelty among Americans. Paine’s writing is very effective because he uses simple, comprehensible arguments to present complex ideas. He analyses the situation systematically, with due recourse to the general rules of governance and arrives at the solution of a democratic self-governance for American colonies. Though the persuasive elements rely a lot on an explication of the existing system of monarchic and aristocratic rules, the concepts are made clear in everyday terms, thereby helping people from all walks of life identify with his views. The Declaration of Independence was formulated by a group of

Courage Mother and her Children critique Essay Example for Free

Courage Mother and her Children critique Essay â€Å"Mother Courage and Her Children† by Bertolt Brecht took place during the 30 Years’ War in Europe. The whole play revolved around the survival of a lower class family, trying to live through the harsh war with their canteen wagon business. Each scene in the play contained the factors of religious, honesty, war, loyalty, and family. The theme of â€Å"Mother Courage and Her Children† was maternity, due to the fact that Mother Courage’s sense of coldhearted business caused her become unable to protect her children, which led to their deaths, leaving her all alone in the end. Mother Courage was always doing business while each of her children died during the play. This shows that she was more interested in her business and money than her own children, and an example of this can be seen when her thirst for money had caused Swiss to die because she took too long to decide whether or not to trade her money in for her son’s life. Mother Courage was the protagonist in the play, while the war was the antagonist. The war caused Mother Courage to base her living on it. Due to the fact that they were living during a war, this caused Mother Courage to be so focused on making money, that she ended up neglecting her children. It also caused her to be unable to watch her daughter get married, since Kattrin could only get married when peace returned and the war ended. War is also the antagonist, due to the fact that is also caused Mother Courage to lose her sons as well. The play was a tragedy because in it, Mother Courage’s children all perished, and she was left all alone in the end. In the play, Bretch assigned each of Mother Courage’s children with a â€Å"tragic flaw† as a result of her failure to learn to choose family over business. The tragedies that Mother Courage’s children suffered throughout the play were Swiss, with honesty, Eilif, with arrogance, and Kattrin, with pity. Mother Courage had to go through suffering of the death of each of her children one by one and was unable to do anything about it. The set of the play was a major contribution to the play. The use of a proscenium stage was the best fit for this type of play since it allowed the audiences to focus on the center of the stage where Mother Courage’s wagon was. Mother Courage’s family always moved around. However, their wagon was still placed at nearly the same spot on the stage, which tells the audience that they were not moving anywhere because no matter where they moved to, they still faced the same struggles and hardships. Even though the setting mostly remained the same from scene to  scene, backgrounds changed from one scene to another, which allowed the audience to know that the scene was taking place in a different location. There was almost always the same lighting throughout the whole play. The only thing that changed about the lights was the brightness; the lights were brighter during the day and dimmer at night. There were some spotlights. However, it only appeared upon the actors who came before each scene, in order to tell the audience what will happen in the upcoming scene. The lighting of â€Å"Mother Courage Mother and Her Children,† was different from the other play that I went to. Usually lights would go off when changing from one scene to another, so that characters were able to get on and off stage, in order to prepare the set for the scene. However, in this play, the lights were still on during scene transitions. Bretch made pulling the wagon in and out of the stage as an exit and enter for each scene, which didn’t require the actors to quickly change settings for different scenes. The background sound of gunshots and bombs that were playing throughout the play allowed the audience to feel as if the war was actually taking place during the play. The gunshots sounded very loud, making the audience feel as if it was nearby. Without the sounds, the audience would not have been able to feel the mood of the war. Sounds of gunshots added more effects to the mood of war, giving the audience an the image of how deadly the war was. The play was a musical play, since there were many parts where Mother Courage and some singers in the background sang and played instruments. The entrance to the play was also a song that expressed the mood and feeling of the war. Mother courage sang in almost every scene, to express her feelings. She also sang in the last part of the play when Kattrin died. The costumes of the play reflected the life of the characters in the play. The costumes did not really tell the time period in which the play took place because the characters were just wearing normal types of rural clothes that had many layers, and were attached with many pieces of fabric. The characters in the play had the same outfit throughout the whole play, and this outfit not only showed their poverty, but also the condition of life during the war, due to the fact that they were unable to have clothes to change into. The many layers of clothes worn were everything that the characters owned, and this showed their struggles, due to the fact that they are unable to buy any new clothes. Overall, the play was easy to understand because it was in modern  English and there were no accent in the characters’ pronunciation, which allowed the audience to understand what the characters were saying. Mother Courage struggled throughout her life with her business and children, but ended up with nothing due to the war, in which she was favoring. The war had brought Mother Courage the business she needed, but took away her children one by one.

The Smart Metal Detector

The Smart Metal Detector This project is the combination of hardware and software product. With the aid of the micro-controller, this metal detector can have more useful function. This system consists of 3 main parts of hardware: The construction of smart metal detector required the gathering of information/ knowledge/ concepts of obstacle sensor, LCD Display, H-Bridge DC motor driver, PIC micro-controller, metal detector technology and so on. Besides that, some knowledge in software part: PIC Assembly language and other useful software: MPLAB, Protel XP, and multisim are also needed. Nowadays, Metal detectors have become a very common staple in todays society and widely used in human live in a range of usage from leisure to work and also safety purpose. For Safety purpose, Metal detector that used in airport to ensure that there is no dangerous weapon such as knives, guns or any metal objects that could be used as weapons has been brought along by terrorist into the airplane. In technical area, people used metal detector to search for the underground pipe or cable before digging in walls and floors. Besides that, many people enjoy in discovering hidden treasure or valuable metal like gold and silver by using metal detector. Metal detector products are available in market. It has many types of metal detectors are sold which used in different area. However, many of them have the following disadvantages: Expensive The prices of metal detectors are very expensive. Although the more expensive metal detector has higher performance and functionality, usually we dont need so much of the function. The extra function that we dont need will be wasted. So the prices of metal detector products that sold in market wouldnt be afford by everyone. Manually controlled metal detector Many of the metal detectors are manually controlled by human where users are required to handle it and walk around to detect the underground metal. This is very exhausted and tired work. Based on these two disadvantages, users need a low cost and have basic function of mobility metal detector. The smart metal detector is a device that used to detect metallic material such as coins, gold and other metal items. It can move and change the direction of movement in certain situation to scan the underground metal. It will take a U turn when it reached the desired distance which already set inside the microcontroller and continue move in another track. It will avoid the obstacle with the help of sensor. When it detects a metal, it will beep on alarm to indicate user. 2.0 Statement of Aims Below are the aims that targeted to achieve in the Smart metal detector project: Automatic movement: In this section, the concept of relationship between H-Bridge driver and DC motors are applied into the project. The H-Bridge driver is a circuit that used to control the direction of DC motors with the help of micro-controller. Obstacle avoidance: When the device has detected an obstacle blocking in front of the metal detector, it will avoid the obstacle automatically by changing its movement direction to prevent collision happened. Micro-controller application: A micro-controller is used to become the main brain of the mobile metal detector. The main purpose of the micro-controller is used to give instruction to control all the function of the metal detection. Alarm beep when detect metal: When the metal detector has been detected underground metal, the buzzer will beep on to inform users that some metal elements have been detected. LCD display indication: All the status and message from the metal detector are indicating in the LCD display. For example, the message of Metal Found will be shown in LCD when the metal detector has been detected metal element. 3.0 Objective The main objective of this project is to develop a Smart Metal Detector into more automation area. With the automation of metal detector, this concept will be contributed to the real life application. The sub-objectives of this project will be elaborate below: To apply the electric and electronic knowledge that I have learned into the real application field. To provide a low cost metal detector for general metal detection purpose. To learn the skill of writing software in PIC Assembly language. To learn the skill of debugging the software problems or bugs. To learn how to work followed the planned schedule, as well as the Gantt Chart. 4.0 Literature Review The first person that invented the first crude metal detector in 1881 was Alexander Graham Bell. After that, the metal detector concept has been kept on improving to become more advance and applicable in various areas. Basically, there are three technologies used in metal detectors. These three technologies are: I. Very Low Frequency (VLF) Technology II. Pulse Induction (PI) Technology III. Beat-Frequency Oscillation (BFO) Technology VLF is known as induction balance and it is also the most popular metal detector technology used nowadays. There are two distinct coils that used in a VLF metal detector, transmitter coil and receiver coil. The transmitter coil is the outer coil loop which is coiled with wire. Electricity is being sent along the wire and creates the electromagnetic field. The receiver coil is the inner coil loop which is also coiled with another wire. The receiver coil acts as an antenna to pick up and amplify the frequencies which come from the target metallic objects in the ground. The metal detector has the ability to determine approximately the deeper of the targeted buried object. This can be done by determine the strength of the magnetic field that the object generates. The concept is very simple: The stronger magnetic field will be detected if the metal detector is closer to the surface of the targeted object. Alternately, the further the object away from the metal detector, the weaker the magnetic field will be detected. The metal detector also can differential the types of metals. It is relied on a phenomenon called as phase shifting. The differences in timing between the frequencies of transmitter coil and the targeted object is called phase shift. For example, an object with high inductance will have a larger phase shift because it takes longer time to alter its magnetic field. However, an object with high resistance will have a small phase shift. The phase shift concept provided VLF based metal detector has the capability called discrimination. The metal detector used a pair of electronic circuits called phase demodulators to compare the phase shift of target object with the average of a particular type of metal to examine the metal class of the target object. The detector will then notifies user with audible tone or visual indicator of what class of the metal is most likely to be. The phase shift concept also allowed user to filter out (discriminate) the unwanted object above a certain phase-shi ft level. Pulse Induction (PI) technology is a less common form of the metal detector. PI metal detector uses only single coil as both transmitter and receiver, or using 2 or 3 coils work together. The metal detector sends powerful, short pulses of current through a coil of wire. This cause each pulse generates a brief magnetic field. The magnetic field will reverse polarity and collapses very suddenly after the pulse ends and causing a sharp electrical spike. After the spikes, a current called reflected pulse will run through another coil and this process will keep on repeating in very short time. The PI based metal detector works like echoes: If the metal detector is over a metallic object, an opposite magnetic field will create by the pulse in the object. After the collapsing of the pulses magnetic field, the reflected pulse will be generated, and thus the magnetic field of the object cause it take longer time for the reflected pulse to disappear absolutely. A sampling circuit is set to monitor the length of the reflected pulse. The circuit can determine if another magnetic field has caused the reflected pulse decay in longer time (usually a few microseconds) than normal, it will suspected that some metallic object is being interfering with it. Usually the sampling circuit is connected to a device called integrator. This integrator can read the received signal from sampling circuit amplifies and converts the signal to direct current (DC). This DCs voltage is connected to an audio circuit which used to indicate the user that targeted object has been detected. This function is almost similar to the VLF based metal detector. PI based metal detector is not as good as VLF based metal detector in discrimination due to the limitation of reflected pulse length of various metals are difficult to separated. However, PI detector is very useful to detect object in areas that have highly conductive material such as salt-water exploration. In addition, PI detector has the advantage that can detect metal much deeper in the ground than other systems. Beat-frequency oscillator (BFO) technology is the most basic way that used to detect metal. There are 2 coils of wire in BFO detector. A large coil is in the serarch head and the smaller coil is located inside the control box. Both coils are connected to an oscillator that generates thousands of pulses of current per second. The frequency of the pulses is slightly offset between two coils. When the search head passes over a metal object, the objects magnetic field will interferes with the frequency of the radio waves which generated by the search head coil. After that, the frequency will deviates from the frequency of the coil in the control box and cause the audible beats change in duration and tone. The BFO detector is sold in low cost compare to other technologies detector, however, the accuracy and the level of control are not provided. Although there are 3 different of technologies used in metal detector, the basic concept of metal detector can be simplify as using the coil of wire to detect the magnetic field of the underground metal. Hence send a feedback signal to main circuit or micro-controller to process it. Those metal detectors have various types of function and advance performance however; most of them are manually controlled by human. This project is basically applied the technology of metal detector into a more automation field instead of using human control, but not improving of the performance of any market products. 5.0 Design Methodology In order to complete the project in time, I have separated the whole project progress into several parts. The project development progress is shown in the flowchart form: Planning Literature research Literature Review in background knowledge of metal detector. Information of hardware/components gathering Software learning Components purchasing Hardware constructing (Prototyping) Testing/Experiments Writing software (Programming) Modify Prototypes Software improving Testing Troubleshooting/Debugging Final Assembling Project Completed 6.0 Research and Competitive Analysis The hardware part of smart metal detector consists of inputs and outputs. The input parts included: obstacle sensor and metal detector circuit. The output parts included: H-bridge driver, DC motors and buzzer. A micro-controller is used to interconnect and control the operations among the hardware components. It receives input signals from different inputs and gives the instruction to the outputs based on the situation. The micro-controller will only execute the program that stored inside the memory. Micro-controller works as the brain of the Smart Metal detector. It gets the feedback signal from the sensors/detectors then sending signal to control the condition of the H-Bridge driver and turn on the buzzer once metal is detected. Obstacle Sensor to detect obstacle that blocking in front of the mobile detector to avoid collision happened. Metal detector used to detect the underground metal/mine. The metal detector circuit is uses the coil/inductor to detect the magnetic field of the underground metal. When the coil/inductor cuts the magnetic field of the targeted metal, it will send a feedback signal to the micro-controller. LCD Display can have a better looks and more powerful in showing message instead of using LEDs or Seven-Segments display. It displays the message in the form of alphabet or numbers. So, user will have a better understanding in reading the alphabet message compared to just light on some LEDs. Buzzer/Alarm acts an alarm to warn/inform user that something has happened to the metal detector such as mine has been detected. H-Bridge driver and DC motors used to control the direction of DC motors for different condition such as move forward, stop moving and turning. The DC motors are used to rotate the wheels of the mobile metal detector. 8.0 Software Flow Chart The programming code is written to interconnect the input hardware and the output hardware. The received signal form inputs will be process in the microcontroller and thus send out the react instruction to the output parts. The PIC assembly language is used in this project. The programs of the basically project can be separated into 3 main parts: Main routine of moving. Obstacle avoidance. Metal detected. The estimated cost of this project is to prepare a fund which enables us to control the project expenses. For this project, a sum of RM 615 will be allocated to fund the entire project including the hardware and software parts. The cost of the project can be reduced to a certain amount by doing market research and comparing the cost among the vendors. In addition, compare different type of metal detector and obstacle sensor also needed to reduce the project cost. Another alternative is to get second-hand or used goods in order to minimize the expenditure. Besides this, daily wages must also take into consideration. Considering 400 hours will be utilized to accomplish this project and RM 5 per hour will be paid. Yet another RM 150 is allocated to fund the resources fee such as the electricity and petrol usage. Hence, the overhead cost for this entire project will be charged at RM 2765. 11.0 Risk Assessment and Management To complete this project, a few risks that might affect the progress of the project have been drawn out as prevention is better than cure. If there is no other alternative plan has been made or planned now, then it will definitely leave a bad impact to us if this risk does happen. Firstly, in order to make this project a success, intensive learning of assembly language through reference book and Subject EN0318 Embedded Systems Advanced Digital System Design is crucial because I am lack in PIC knowledge and it is new to me and it posts a risk to me. 12.0 Conclusion and Recommendation Now just a beginning stage of the project, I have provided a clear view of the objectives and aims of metal detector project and i will complete the entire task stated step by step by following the project planning time. My project planning has stated clearly through the Gantt chart as well as the critical path analysis. The entire research and development job has been done throughout this semester but it still in the early stage the final project. Hence, more information from supervisor, reference book and internet needed. I can increase my knowledge level by workout with the research activity and this may help me to boost up my project to quality completion. In addition, found that many interested features and ideas can be added on to the project. But the insufficient time, knowledge and financial problems have restricted me to achieve those extra features. However, if possible I will try my best to achieve it. The extra features are: Measuring of the deeper of the underground metal Password is required to activate the metal detector Robot arm added to the mobile metal detector As a conclusion, this project smart metal detector may give me experience as an equipment and product engineer with excellent technical and management skills with moral values and bring future benefits to me as an engineer. 13.0 References [1] http://travel.howstuffworks.com/airport-security.htm [1] http://www.losttreasure.com/auction/APViewInCat.asp?ID=7 [2] http://inventors.about.com/library/inventors/blmetal_detector.htm [3] http://home.howstuffworks.com/metal-detector1.htm [4] http://www.microchip.com
