Reproduction results with zoom/without zoom and info signals27 Section 1 Introduction A satisfactory blood stream gracefully is fundamental for all organs of the body. Examination of the blood stream discovers its significance in the judgments of sicknesses. There are numerous strategies for examining the blood stream. These procedures are not reasonable by the destitute individuals on account of their high cost. So we have executed a procedure called Zoom-FFT. This method is basic and moderate to recognize the blood coagulations and different illnesses. Human with his latent capacity attempts to get whichever is unexplored, investigated, and till now we are overseeing and succeeding utilizing some specialized ways. Similarly this is one of the investigations made for examining the intra subtleties of some particular articles utilizing ultrasound named SONOGRAPHY, which is utilized as an option in contrast to x-beam photography. In this paper, the strategy to zoom the picture or the checked information utilizing zoom FFT has been talked about. It additionally discloses the calculation to get ZOOM FFT and how it tends to be gotten by means of reproduction. Constant experimentation and its applications, with fundamentals of ultrasound examining are additionally clarified. Here a particular application will be managed I. e. , ultrasonic blood stream analyzer utilizing ZOOM FFT. Blood stream investigation is finished by passing a high recurrence ultrasonic wave in the veins through a transducer (transmitter) . The reflected sign; from the recipient transducer has an alternate recurrence because of the Doppler standard. This sign is passed to a DSP processor to discover the recurrence range. Due to the high recurrence of the ultrasonic wave, the goals of the recurrence range yield won't be acceptable. Consequently we go for cutting edge Zoom FFT procedure, wherein an extremely little recurrence change because of the coagulation arrangement can be acquired with a decent goals. It tends to be utilized to find the underlying nearness of a blood coagulation. These undertakings must be accomplished with a solitary DSP chip all together for the framework to be both financially savvy and force proficient and therefore broadly acknowledged. This course report proposes: 1. Investigation of Bio-clinical sign handling 2. Blending down the info sign to the base band recurrence utilizing Hilbert Transform 3. Finding the down examining utilizing the annihilation procedure 4. Getting the range yield utilizing quick Fourier change 5. Reenactment is finished by Matlab/C. 6. TMS320C5X/6X DSP processor does continuous execution. SOUND IS A COMPRESSIONAL WAVE† Sounds at frequencies over the discernible range, to state over 20 KHz are Ultrasonic wave, in the megahertz go. Above which are supersonic sound. 1. 1 DOPPLER EFFECT PHENOMENON A move in recurrence (f) of the wave will be relied upon because of the source and spectators movement comparative with one another. On the off chance that the separation between them is decreased or expanded. That move in recurrence relies upon the speed of sound which likewise relies upon thickness of the medium, in which it proliferates. At the point when a little article is arranged in the way of the sound wave, the wave will be opposed (dissipated). An immediate estimation of this speed will give valuable data about the dynamic property of the medium. The Velocity of sound in Blood is 1570 m/s. Seen speed is V’=V-V0 as far as recurrence (f), as a speed subordinate factor. Fp = f0 (V+V0)/V-Vs, for the two items moving towards. †(1) Fp = f0 (V-V0)/V+Vs, for the two articles moving ceaselessly from one another. †(2) F0: Actual Frequency. Fp: Perceived Frequency. V: Velocity of Wave. Versus: Source Velocity. V0: Velocity of Observer. Subsequently we get the apparent recurrence proportionately changed regarding changes in estimating media. This procedure is clarified utilizing movement as beneath in FIG (1). Fig. 1 Doppler Effect The Doppler Effect can be disclosed as for pitch or frequency, since all are reliant to one another. E. g. of Doppler Effect: Say, A vehicle passes you on the road blowing its horn at a recurrence of 440Hz, the entire way, As the vehicle approaches you, you will hear a pitch gt; 440Hz(in expanding request). After the vehicle passes you and drives from you, you will hear a pitch lower lt; 440Hz (in plummeting request). â€Å"THIS CONCEPT IS APPLIED IN ULTRASOUND RANGE FOR HUMAN BLOOD FLOW ANALYSIS USING VELOCITY OF BLOOD† Steps included: Sound age: The ultrasonic sound is produced utilizing the piezoelectric transducer. * Number of transducer may fluctuate from 1 to many. * Narrow light emission is to be feed in. * Continuous method of activity with no planned exchanging is applied progressively to quantify Frequency and Amplitude * Doppler move examination for recurrence content is to b e finished. * Creation of picture †to plot in 2 Dimension. * Display utilizing shading separation. 1. 2 REAL BLOOD FLOW ANALYSIS: In a Ultrasonic blood stream investigation, a light emission vitality is coordinated through a vein at a shallow edge and its travel time is then estimated. Progressively normal are the ultrasonic analyzers dependent on the Doppler guideline. An oscillator, working at a recurrence of a few Mega Hertz, energizes a piezoelectric transducer. This transducer is coupled to the mass of an uncovered vein and sends a ultrasonic shaft with a recurrence F into the streaming blood. A little piece of the transmitted vitality is dispersed back and is gotten by a subsequent transducer organized inverse the first as appeared in.

Mathew Kohr versus Starbucks - Assignment Example Prior to the jury, Starbucks reacted by contending that since some espresso was offered for nothing, Mr. Kohr isn't secured by comparative assurances as that of a paying client. In any case, WRAL revealed that the contention of Kohr was because of the way that the complimentary gift is just offered to formally dressed officials, which settle on up an understanding between the organization and him. Once more, during the preliminary, Kohr admitted that he needed to commute home with the goal that he could snap a picture of the injury before looking for clinical consideration later. He returned home with the goal that his significant other could take photos of the consumes he had continued on his inward thigh. The legal advisor who spoke to Starbucks, Tricia Derr demanded that Kohr neglected to visit a consideration community critically till over two hours passed. Initially, the Kohrs referenced two baristas for the situation, including the International Paper, who is the producers of t he cups, before coordinating the suit exclusively at Starbucks (ABC News, 2012). The representative for Starbucks referenced that the organization serves four billion espressos in the paper cups, and just fifty-nine of them had fell. Part OneThough Kohr and his significant other didn't remark concerning the choice, legal counselor Daniel Johnson said that the choice disillusioned them without a doubt. Then again, Starbucks referenced that the choice made by the jury was satisfying, including that it had a conviction that the laborers didn’t do anything wrong.In any respectful activities that occur in the government court, both of the gatherings may make the pre-preliminary movement for rundown judgment.

A Negative Effect Of Police Brutality - Free Essay Example

Even though it has been around for decades, through recent years police brutality has been the topic to talk about, with the recent killings of innocent people how could it not be? This issue truly does have a negative effect on society many people relating the topic as a hate crime because its mostly colored minorities who are affected by this. There are things being done and there are also some things that could be done to prevent this from occurring. Police brutality is when an officer uses an excessive amount of force on a person. For example, Dashawn Mcgrier, having already been charged with assault, disorderly conduct, obstructing and hindering, and resisting and interfering with arrest. On August 11 a video was posted showing an officer who had previously detained him continuously punching Mcgrier in the body and head. While Mcgrier did nothing to the officer but try to defend himself from the blows he fell on the ground and the officer didnt stop. When a person sees this it gets them wondering on if they can really trust another man in a police uniform. In a persons mind a police officer should be there to help a citizen when in need not attack them because they may feel a certain way towards them. In the In Police We Trust article, it states 75% of white Americans believe that the police do an excellent or good job in treating racial and ethnic minorities equal and only one-third of blacks believe the same. police brutality has become a big topic lately because of the killings or abuse of power a police officer may show. Police officers were made so people could be safe and protected. With the current representation of what a police officer is to some people, trust is lost to those who are supposed to protect them. How are people supposed to feel safe if they see and hear that police officers are being extreme or going to the point of killing a citizen? This is a huge problem because people could make this as a reason to turn against law enforcement and cause chaos in a community. Prior to current cases of police brutality, it all really isnt new in America. During the 1960s civil rights movements were going on for black freedom and equality. In the peaceful marches of integrationists, at some point they were beat with sticks, fired at with tear gas, punched or attacked by dogs sometimes. Of course the most famous and memorable march where all of these occurred in was the Selma march to Montgomery in 1965. It doesnt stop there, on March 3, 1991. Rodney King a motorist, was stopped by officers from the LAPD for speeding. As a result for not following police orders King was hit by knight sticks about fifty times. In the video, which was filmed by a nearby pedestrian, there are two officers who beat him with the night sticks and more than a dozen other officers who just stand there and watch as they beat the man. This was the video that really caught the attention of the people, and showed that there was truly another side in law enforcement, that being the cruel and abusive side. Police brutality is never not happening in america, thats why people are growing to hate these crimes or the police themselves. A common attempt thats been done for this issue is to have a camera on the officer while on duty. They wear these cameras for both the officers and citizens protection. The officer having the camera on i feel causes them to think before they do because they themselves are recording every single thing they do. If they dont think before they do then the camera catches that and the officer cant deny what he or she did. Recently though they had to take those cameras off because the battery would explode while on the officer. Another approach to this is the creation of reforms to minimize the numbers of these devastating occurrences. An example of this would be written in the article How much is Police Brutality Costing America, which states, The city of Camden, New Jersey started over with a new police force focused on community policing; after doing so, it rates of violent crime and murder fell. If we could get the police officers to get to know the community and the people who are in t hem the possibility of police brutality would be lower then if an officer didnt know anything or anyone. This would help build trust in citizens to law enforcement officials in their community. To have a kind of relationship with each other would make it safer for both the officer and citizen because they dont have to worry about starting off aggressive at first but instead approach each other camly, and only use force when needing to. In my opinion officers who misuse their power are not worthy of having the badge they carry on them at all. One thing that could be done is hiring people who want to protect and serve all people , not excluding anyone because of their color or beliefs. Something that could also be done is possibly seeing if anyone has anger issues or doing check ups on law enforcement officer to see how they are doing mentally. I feel that a cause to the police brutality is the officer may get easily hostile because of something or someone that got them mad or touched them when they want to be. People have to go through court when they do something against the law, but for law enforcement officers, they should go to court yes, but the courts should be more strict on them. As in, if there is evidence that they were the officer to commit the crime they should get laid off, and if they witnessed another officer do this wrong and did nothing, they can still work for law enforcement but cleaning their flo ors. What is the whole point of having two officers partners, if one isnt going to to step up and keep the other in check. To do something when they know the other is doing something wrong is best. To be a police officer is to protect and serve not go against the citizen or standby and watch.

Puritans And The New England - 1344 Words

Puritans were a group of English Protestants who believed that the Reformation of the Church of English was still to stuck on Catholic formalities and wanted to simplify and regulate types of worship. The Puritans left England out of a need to purify the church and their own lives. They followed the writings of John Calvin to America and formed The Massachusetts Bay Colony. The Massachusetts Bay Colony was one of the original settlements, settled in 1630 by a group of about 1,000 Puritan refugees from England, under the guidance of Governor John Winthrop. In 1929, The Massachusetts Bay Colony received a charter from King Charles I allowing them to colonize in New England between the Charles River and the Merrimack River. The Puritans created a government with theocratic rule which was limited to church members. The Puritans initially settled in Boston in 1630. After Boston, they settled in Cambridge, Lexington, Concord, Watertown, Charlestown, and Dorchester. The Puritan population, in New England, rose from 17,800 people, in 1640, to 106,000, in 1700. The beliefs of the puritans were simple and straightforward. They believed that the Bible was God s true law and it provided the blueprints for a righteous life. People who did not agree with the Puritans theological views were advised to disperse from the area or convert to the popular beliefs of the majority.

Classical ethical principles in ICT -MyAssignmenthelp.com

Question: Discuss about the Classical ethical principles in ICT. Answer: Classical ethical principles in ICTfor the self-driving cars in Australia: Now, the time has come that the organizations need to be aware of the ICT Ethics in their company. The places where the progress is to be made, where the challenges or limitations exist and the future potential are needed to be identified (Goodall, 2016). The following essay has identified the case of driverless cars changing Australia. The classical ethical theories are applied on it. Lastly, the justifiable and logical conclusions are derived to solve the ethical problems. The most exciting technological development of ICT is on the horizon in Australia. However, the creation of driverless vehicle can devastate Australia. The economy of Australia has been depending highly on the logistics and transport industry. This could demolish the jobs of truck drivers with far-reaching impacts. The outline of the transportation industry has been strongly tied to the wider economy. It is not a surprise that the rise of the transport sector has been tracking nearer to the GDP rise ("The jobs killer is coming", 2017). The companies like Uber have been reducing the standards of the labors by stealth. This is done through employing the drivers as the independent contracts. This has not been supplying any profits that were possessed by the Australias generations. The Uber has been undercutting the present standards of poor labors existing in the taxi industry. The industries are bound to lift the standards not permitting them to be decreased further. Moreover, they hav e urgently needed the strategy for deciding from where the quality jobs of the future will arise. The drivers could be left without jobs and there have been concerns regarding the supposed technology resulting in chaos to the crucial industries (Nyholm Smids, 2016). The driverless trucks are still semi-automated and the human drivers would need to advocate the admitting of particular issues, required to be ironed out, despite the computers perform the driving. The safety issues would not be eradicated as the technology has not been infallible. There has been also inevitable catastrophically mismanagement of the driverless vehicles. This would no doubt happen just as presently few heavy vehicles have not been maintained rightly resulting in fatalities (Bringsjord Sen, 2016). The challenges with this technology must indicate the disaster on the larger scale with the unmanned drones and the warships eradicating the weapons that are human operated. The civilization must require making few dramatic changes for adapting the driverless cars in new reality. Let in case of an unavoidable crash, the car needs to go for crashing with two distinct sets of people. The utilitarian approach, a popular classical theory of ethics would opt for the least loss of life. This is because there has been a clear aim to reduce harm to human, morally the most effective approach benefiting the wider society (Lin, 2016). This method is the most intuitive. This is because it is expected from the artificial machines to take decisions on the basis of algorithms. No emotion is taken into account here. This is the most natural development for the intelligent systems. This is because the technology makes use of the rational approach and most logical to consider. The ethical considerations could be on the basis of the principles of utilitarianism that are constant and not influenced by the occupants of the state of mind of the vehicles. This analyses the safety of the autonomous vehicles regardless the passengers are intoxicated or unable to drive. Thus it reduces the risks regarding the vehicle being programmed for driving in a less perfect way. The programming constancy if programming of various vehicle manufacturers leads to lesser legal ramifications for everyone (Bonnefon, Shariff Rahwan, 2015). As one manufacturer uses the alternative programming, it is used to make the vehicles safer for the drivers. Through using the utilitarian method to program the self-drive vehicles indicates that they are created to be programmed in the similar manner none of the cars cannot prioritize the life of the driver. This must be rather than what has been in the best interest for everyone. The programming of utilitarian is simpler to impose. This is because the ability to make decisions has been only based to reduce the loss of life in any case. The ethical systems like the virtue ethics need complex computation for deciding the most suitable course of action in the situations of inevitable crashes (Belay, 2015). The utilitarian process minimizes the expense to develop the technology and simplify the needed programs. This could also the playing sector between the low and high-end manufacturers of car and improving the consistency. Further, the insurance companies could see the approach of social contract must easier in comprehending. Moreover, the premiums get lowered compared to other ethical frameworks. This has been because of the simpler calculations for the insurance brokers who have been pricing the strict decisions of the social contract made by the vehicle for the humanitys best interest (Goodall, 2014). The online services have been already delivering the automated proposals for latest services and products. These are a few cases the possible invasions of privacy. The usage of the social contract algorithm needs no personal data for the vehicles in modeling itself as the human driver, unlike the virtue ethics. Thus it has been reducing the quantity of the privacy infringement. Again the social contract has been bound to the psychological facts as by the legal and technological ones. The modern-day government is the result of the implicit agreement also known as the social contract (Goodall, 2016). In this way, the self-automated cars could be conceived as they try to embed the will of the machines into the algorithmic social contract. The deontologists, on the other hand, could struggle with the concept of the computers having the free will while acting to avoid the crash. While the car could make choice between the killings of any pedestrian or any driver is a good intention or simply the process executed and carried out arbitrarily is raising concern (Bonnefon, Shariff Rahwan, 2015). However, an ideal deontologist must be in the favor of the self-driving cars since the opting to use the safer self-autonomous cars at first could override the decisions made by the technology of the cars. The report has shown how the ethical principles could be applied to the self-driving cars. It has applied the classical ethical principles where it could be applicable. However, the autonomy is unable to save all the people. The technology can never be perfect. The society needs to remind this before arriving of the technology. They also need to understand that this innovation for greater good. To convince the public should start the understanding what the public has been worried about and the psychological mechanisms involved. The self-driving cars possess bright future. However, this can only happen as the public overcomes the psychological issues standing in their way of the widespread adoption. Another ethical aspect of this industry which requires development has been how the people describe and set the expectations from the viewpoint of the consumers. Moreover, the consumers are needed to be educated more regarding the technology of autonomous vehicle. In this way they could be informed about the easy in the vehicle would be operating along with its responsibilities. As the consumers make sense of the long-term and immediate advantages of the self-driving cars, they could be provided with the green light. References: Goodall, N. J. (2016).

Theories of Play free essay sample

Child development was previously largely ignored, and there was little attention to the progress which occurs during childhood and adolescence in terms of cognitive abilities, physical growth and language usage. However, researchers have found interest to study typical development in children as well as what influences development. Many theories have emerged which have helped full understanding of the social, emotional and physical growth which occurs in a child from early childhood to early adulthood (Hughes, 2004, p. 0). Jean Piaget proposed one of such theories and looked human development in a biological angle and explained it in four development stages. The stages are sensorimotor development stage, preoperational development stage, concrete operational development stage and formal operational development stage. However, Vygotsky proposed another theory of cognitive development which looked development in social interaction point of view. Although these theories differ in some a spects, they both consider playing as a key element in child development. We will write a custom essay sample on Theories of Play or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page This paper will discuss Piaget and Vygotsky theories of development and attempt to relate play to the theories. In addition, the paper will cover the applications of these theories in real life situation by giving real life examples, as used by teachers to their students. Piaget looked at the cognitive development concept from a biological point of view. To him, the key principles in the child’s growth and intellect are adaptation and organization. This theory indicates all organisms should have the ability to adapt to the environment, which is a necessity for survival. According to this theory, learning involves constructivist process thus knowledge is not acquired from the environment and imitation of other people’s actions. Rather, knowledge is acquired through a slow but a continuous process of learning. Piaget noted that children need three basic kinds of knowledge in order to develop; they need physical, social and logical-mathematical, and psychological knowledge (Hughes, 2009, p. 29). This theory also notes that physical knowledge is essential for survival and growth of the body. Physical knowledge is obtained by performing activities which allow children to observe and make conclusions of physical characteristics of objects. On the other hand, social knowledge is obtained from experience when a child interacts with other children. Children are, therefore, able to apply what they gain from social situations. Logical-mathematical knowledge allows children to discover the relationship between objects, ideas and people. Lastly, psychological knowledge is essential for the growth of intellectual structure of a child’s mind. According to this theory, adaptation encompasses two stages, assimilation and accommodation process. Assimilation involves taking in new things or ideas, from the outside world and trying to fit it in the existing structure. Children take information and use it at their pleasure without necessarily adapting their thinking to it. The accommodation process involves the existing structure adjusting to new acquired materials. The physical body reacts by internal process, such as digestion, and responds by growing and changing in size. On the other hand, minds reacts by accommodating new intellectual materials and responds by growing intellectually (Oakley, 2004, p. 27). In the development of a child, play is a crucial element to consider. This is essentially because, as children play they encounter (assimilate) new material. If the new ideas are not fitting to their current knowledge, a sense of confusion will result (disequilibrium). Thereafter, the child may master new idea by adjusting current ideas (accommodation) to the new information and, therefore, learn something new. To Piaget, there are four critical stages which a child must pass through during cognitive development (Watson, 2004, p. 38). First, there is sensorimotor stage, which starts from birth to about two years, apply motor activity without the use of symbols. Children gain knowledge through physical interaction and experience, however, knowledge is limited at this stage. They learn through trial and error since they cannot predict reactions. However, as children become more mobile, their abilities for cognitive development increases and early language development begin. Between seven to nine months, children develop object permanence, and they realize that an object still exists even after it is out of their sight (Keenan, 2009, p. 24). Preoperational, Stage which occurs between two and seven years, is the second stage in cognitive development. During this stage, children begin to use language as a way of communication and their memory and imagination develop. They also engage in make-believe and they in symbols which allows flexibility and planning in their problem solving skills. During this stage, children are egocentric; they think all people view the world as they see (Martin, 2008, p. 0). They also begin to remember past events and even imagine future events (Watson, 2005, p. 65). Concrete operational is the next stage of Jean Piaget theory of child development. The third stage occurs between seven and eleven years. The stage is marked by conservation whereby a child understands that things still maintains their attributes even if they change their essential appearance. Children begin to demonstrate their intellectual development by using logic and manipulation of symbols which relates to concrete objects. Their egocentric nature of thinking becomes less and their awareness of external events increases (Martin, 2004, p. 40). The last stage of development according to Piaget theory is the formal operational stage. This stage begins when a child is about eleven years. . A child will acquire another level of understanding during this stage, in addition to the ability of, applying logical principles attained in concrete operational stage to more abstract and hypothetical situations. The child, who is now an adult can formulate a hypothesis and be able to think about concepts and abstract relationship. They become interested about the broad social issues such as fairness, justice and equality. Piaget concludes that development is a lifelong process, and new structures are needed after operational stage (Martin, 2004, p. 40). Piaget theory of development can be used in school for development and growth of children. The implication of this theory is an adaptation of instructions to the development of the learner and the instructions should be consistent with the learner’s level of development. The role of a teacher is to facilitate learning of through the provision of a variety of experiences. This will enable a child to experiment and explore, which in turn encourages new understanding. Teachers should use concrete hands on experience to allow students learn and acquire another level of understanding (Watson, 200 4, p. 65 and 66). Piaget theory has found wide application in school. For instance, the teachers teach children through sensory experiences whereby they are given objects to touch, smell and taste. As the children grow, they can be given texture names, colour names, colour names and the names of the objects around them. In addition, they can also be taught new vocabularies accompanied by pictures; however, teachers should keep in mind the level of their understanding. As they progress, children are given complex problems, e. g. maths, whereby they are required to use logic. They are, therefore, able to make more connections with reality rather than fantasy. Secondly, children can be involved with plays like hide and seek at the primary level. These kinds of plays help them to develop physical skills and enhance their coordination. They can also be involved with game of numbers, riddles and coded messages. As they grow, their plays become more organised and structured. Teachers can organize games and sport events with rules. This level teaches them that winning comes as a result of following the rules. As they progress, they can be organised into clubs and team sports which helps them in understanding how they can fit to the societal system. Vygotsky proposed another theory for cognitive development. This theory places emphasis on the fundamental rule of social interaction in the child’s cognitive development. It notes that community plays a significant role to develop a child and that they adapt through their cultural and social interactions with people who are more skilled, such teachers or parents. The basis of this theory is the idea that children will use tools such as language, maps and numbering systems in order to develop high level of thinking. According to this theory, language is a hugely critical factor in children development since it helps them to develop new ideas and control their behaviours. They also use language to engage in internal dialogue, which helps in solving difficult task. Vygotsky theory of development is based on three main principles, which are zone of proximal development (ZPD and Scaffolding or more knowledgeable other (MNO). The theory notes that there is a difference between what a child can learn independently and what they can learn under the guidance of skilled instructor. This is difference is captured in the zone of proximity development. Vygotsky sees ZPN as the area in which most guidance and instruction should be given. This will allow children develop essential skills they will later use on their own. He also notes that every day experience plays a vital role in children’s development because they learn through social interactions with skilled helpers, such as teachers or parents. The theory suggests that tutors should use cooperative learning exercises (Martin, 2008, p. 41). On the other hand, more Knowledgeable other principle of the theory refers to people who are more skilful and knowledgeable. When these people interact with children, they provide them with problem solving skills which serves as cognitive scaffolding, which help children to gain the ability to function independently (retrieved from rojects. coe. uga. edu). Vygotsky theory of child development has found a wide application in schools. The current application of Vygotsky theory is in the reciprocal teaching which is used to improve the abilities of children to learn from texts. Here, teachers and pupils collaborate in learning summarizing, clarifying, questioning and predicting, through practicing. Teache rs should also come up with group activities, which allow more skilled peers to interact with less skilled children. With the assistance of adults, children can perform tasks which would be impossible on their own. Scaffolding should thus be used whereby the helper adjusts their level of assistance in accordance to the child’s performance level. Lastly, zone of proximal development should guide assessment methods, which describes what a child can do without the help of a more skilled person. It should consider both actual and potential development of a child (retrieved from projects. coe. uga. edu). Vygotsky theory is can be simplified for quick learning of children. For example, children are shown pennies representing each sound in a word (e. . four pennies for four sounds). In order for them to master the words, they may be requested to place the items on the table showing each sound in a word. Finally, the teacher may ask the children to indentify the words without using pennies. In this case, pennies act like scaffolding to help children move from being assisted to unassisted during a task. In advanced levels, such as high school, a lab tutor may provide students with scaffolding by first giving them detailed experiment procedures and then a brief outline. Thereafter, the tutor may ask the students to set up the experiment on their own. In conclusion, it is clear that Piaget and Vygotsky theories differ in some aspects; however, both theories indicate that children development is a slow but continuous process, which can be achieved as children, interacts with one another, with the surroundings as well as with more skilled persons. These theories, therefore, shows the fundamental aspect of play the development and learning of children. Teachers can effectively use these theories to enhance development of children, but they must take into account their levels of growth and understanding.

The BP Oil Spill in the Gulf of Mexico essayEssay Writing Service

The BP Oil Spill in the Gulf of Mexico essayEssay Writing Service The BP Oil Spill in the Gulf of Mexico essay The BP Oil Spill in the Gulf of Mexico essayExecutive SummaryThis report discusses the issue of concern because an oil spill is considered to be a disaster for both for human beings and the environment. The BP oil spill in the Gulf of Mexico is no exception. The oil spill affected both human beings and the environment, polluting and damaging vast areas of the adjacent territories and the large populations of wildlife. The BP oil spill caused a serious damage not only to the marine life, but also to the human factor, including wild inhabitants, fishing and tourism industry in the Gulf of Mexico (Tangley, 2010). A large number of factors, including Petroleum toxicity, Corexit dispersant usage and oxygen depletion can be viewed as the major causes of the disaster which led to the negative impact on ecological system (Smithsona Venette, 2013).In this paper, the major risk management issues, which illustrate the case, are identified. Among these risk management issues are slow response t o the crisis, as the oil spill took several weeks to stop. The results of risk management assessment demonstrate that loss prevention measures in the case of the BP oil spill in the Gulf of Mexico in 2010 were in place to prevent the oil spillage starting and the proper cost containment steps were taken to manage the cost of the required clean-up operations, recovery procedures to promote business continuation, many days had been lost. Second, the BP oil spill in the Gulf of Mexico demonstrated poor governance of organization as the company lacked the effective crisis plan.Thus, the BP oil spill in the Gulf of Mexico case can be used to teach people lesson how to effectively use risk management and crisis management practices in addressing unexpected disasters.   To manage the crisis, a special plan should be developed and tested. Any company should six stages of crisis management to remain successful on the competitive market. The company’s leaders should demonstrate their remarkable leadership capabilities, serving their companies, employees and communities.Introduction and AimsThe Gulf of Mexico is one of the most valuable territories because of the availability of the great variety of marine life, including fish, shrimp and other species. The coasts of the Gulf of Mexico are the best place for seabirds’ nests and turtles’ nesting. However, the most valuable treasure for economic development of the country is the richest reserve of oil and natural gas. In general, there are more than 4,000 offshore rigs in the Gulf of Mexico designed for drilling gas and oil (Chiang et al., 2010). According to researchers, â€Å"many people who live in the five U.S. states that border the Gulf of Mexico (Texas, Louisiana, Mississippi, Alabama and Florida) depend on the Gulf for jobs and survival†(Chiang et al., 2010, p. 5). One more important function of the Gulf of Mexico is the growing fishing industry that provides over 1.3 pounds of fish an d shellfish each year. This information helps to better understand the negative consequences of the BP oil spill in the Gulf of Mexico that occurred on April 20, 2010.   The negative effects from oil spill have been widely discussed in scientific literature. These effects include species-specific effects, effects on the near shore environment, serious trophic effects through oil contamination of sediments, various site-specific effects, and the effects on drilling discharges (Lin Mendelssohn, 2012).   Based on recent research findings, â€Å"the BP oil spill in the Gulf of Mexico that followed the explosion of the exploration platform Deepwater Horizon on 20 April 2010 was the largest accidental oil spill† in America that requires finding the proper solutions to develop effective risk management practices. It is very important to find out â€Å"if an accident of this size could have been expected† (Acton, 2013, p. 501).The general aims of the analysis presented in this paper include:providing an overview of the key facts surrounding the caseidentification of the major risk management issues identified in the caseComparing and contrast the way in which these three risk management issues were dealt with by the firm(s) involved with material presented in the course or other reference material dealing with the concepts or issues that the case illustratesAssessment of the effectiveness with which the crisis, created as a result of the failures in risk management evident in the case, were managedIdentification of the lessons that can be learned from the case, providing conclusions and the nature of any control procedures and/or risk treatment systems that should have been implemented or where failures occurred.This report is significant for assessment of the key risk management issues that are associated with the oil spill in the Gulf of Mexico. The BP’s handling of the Deepwater Horizon oil spill that occurred in 2010 teaches people some i mportant crisis management lessons. Actually, the work on oil platforms is automated, but human errors often occur on these structures (Smithsona Venette, 2013).   According to researchers, these oil drilling rigs are considered to be the largest movable human-made structures in the world, as such â€Å"they have become virtual cities afloat that will always have minor equipment failure and human error, not to mention working in hurricane-prone environments† (Ostrom Wilhelmsen, 2012, p. 23). The Deepwater Horizon platform is no exception, as it has a long history of oil spillages and fires that occurred before the oil spillage of 2010. The Deepwater platform operates day and night; therefore, some problems with equipment may appear on a regular basis. This report is aimed at giving explanation of some important risk management practices that should be taken into consideration by other companies to avoid negative consequences, similar to the Deepwater Horizon platform†™s disaster.Case StudyDescription of the key facts surrounding the caseThe BP oil spill in the Gulf of Mexico is considered to be the â€Å"largest accidental marine oil spill in the history of petroleum industry, being 8%-31% larger in volume that the previous largest oil spill, the Ixtos I oil spill† (Holland Schemwell, 2014, p. 23). The BP oil disaster is often called the Deepwater Horizon oil spill. It occurred on 20 April 2010 in the Gulf of Mexico on the BP-operated Macondo Prospect. Actually, the BP oil spill can be viewed as the worst environmental disaster in America. The BP oil spill occurred near Mississippi River Delta, as a result of a deep-sea floor oil gusher, which was made by the massive explosion of the Deepwater Horizon platform, one of the most efficient and effective semi-submersible drilling rigs in the Gulf of Mexico. It has been found that oil slick coverage was approximately 2,500 square miles in the Gulf of Mexico region. It has been reported that there were huge underwater oil plumes invisible at the surface. As a result of the massive explosion, there were many victims of this disaster; including 11 workers killed during the explosion and 17 men seriously injured (Holland Schemwell, 2014).  On the 15th of July, 2010, the gushing wellhead was capped, but the Deepwater Horizon platform released over 4.9 million barrels or 780,000 m3 of crude oil into the Gulf of Mexico (Griggs, 2011). This fact means that as a result of the explosion, over 53,000 barrels of oil were spilled each day of the accident (from July 10 till July 15) before the workers could cap the well. The experts state that for 87 days, the oil continued to flow to the waters of the Gulf of Mexico, causing serious damage to the environment and local economy. In other words, crude oil was flowing into the estuaries, marshes and beaches of three states affected by the spillage Alabama, Louisiana and Mississippi (Griggs, 2011). The U.S. government declared that the BP oil spill in the Gulf of Mexico can be regarded as a national disaster.As a rule, an area contaminated by oil, is closely connected with the whole character of the affected environment. The free spilling of oil leads to a wide range of negative consequences, including â€Å"the spread by wind and wave† (Bai Bai, 2014, p. 363). The oil spillage from the Deepwater Horizon platform floating on the surface could evaporate through air and sun, spreading over the water surface. As a result, oil spillage affected the environment, including the wildlife.Identification of three major risk management issues illustrated by the caseThe BP oil spill in the Gulf of Mexico that occurred in 2010 gives an opportunity to identify three major risk management issues, which can be assessed by experts as significant risk management lessons. One of the key risk management issues is that â€Å"the oil spill took some weeks to stop† (Hopkin, 2012, p. 175). Although the results of risk management assessment show that loss prevention measures in the case of the BP oil spill were in place to prevent the oil spillage starting and the proper cost containment steps were taken to manage the cost of the required clean-up operations, recovery procedures to promote business continuation, much time had been lost. According to Paul Hopkin (2012), â€Å"it is, perhaps, the case that the damage limitation measures were not as robust as may have been required†(p. 175).Besides, the BP oil spill in the Gulf of Mexico has raised serious risk management issues regarding the governance of organization involved in the case. Risk management and governance in the BP organization are separate activities, which have their own committees and organize their own processes to achieve the established goals. According to researchers, â€Å"the BP oil spill disaster has clearly shown that the board has to own both the general governance of the organization and its many and varied risk activities† (Wright et al., 2013, p. 16). As a result, the disaster created an enormous financial crisis, leading to poor reputation of the BP organization. According to Otto Lerbinger (2012), â€Å"its image as a leader in deep sea technology was shattered, as well as its professed dedication to corporate social responsibility and the environment†(p. 24).   Now the organization needs to use the proper strategies aimed at restoring its reputation in order to successfully operate in the Gulf of Mexico.Based on the US federal government report that was issued in 2011 after investigation of the key causes of the disaster, the following failures were identified:Poor risk management practicesLast-minute changes in decision making (Anastas et al., 2010)Failure to adequately observe and effectively respond to critical indicators that were identified on the platformInadequate and insufficient well control responseâ€Å"Insufficient emergency bridge response training by emplo yees responsible† (Guinness Walpole, 2012, p. 227).Comparing and contrast the way in which these three risk management issues were dealt with by the firm(s) involved with material presented in the course or other reference material dealing with the concepts or issues that the case illustratesIn the case discussed in this paper, the BP failed to avoid certain management errors that led to massive damage to the environment and caused considerable harm to people. The explosion of the Deepwater Horizon platform rig can be viewed as an example of â€Å"a designation that is a prevailing contention of government and other reports on the disaster† (Lerbinger, 2012, p. 24). The disaster in the Gulf of Mexico that occurred in 2010 was caused by certain management failures both by the organization (the BP Company) and its contractors (Transocean and Halliburton). Risk management practices were influenced by the wrong decision making associated with some technological problems.Ac cording to the material presented in the course lectures, the risk management cycle involves several stages, which help an organization to manage risks: Identification, Quantification, Risk assessment, Risk treatment, Monitoring, Risk context. These stages are interrelated (Business Risk Management Week 2, 2014, p. 2). Based on the established components of risk management process, it is possible to avoid negative consequences of disasters in all spheres of human activity, including oil and gas industry. In the Deepwater Horizon platform, many events led to the disaster because inadequate risk management practices were ineffective in that situation.In the case of the Deepwater Horizon oil spill, â€Å"the behaviors and attitudes of leaders have been disappointing at best and irresponsible at worst† (Corkindale, 2010, p.1).   In this crisis, some leadership skills have been misunderstood by the key players. The BP are responsible for the environmental disaster, but the BP CE O Tony Hayward demonstrated some failures in leadership practices, providing control over the â€Å"organizational culture that sanctioned extreme risk-taking, ignored expert advice, overlooked warnings about safety issues and hid facts† (Corkindale, 2010, p.1). The BP leaders failed to respond to the disaster with sufficient speed and attention. Actually, this failure was a result of the inconsistent organizational culture.Assessment of the effectiveness with which the crisis, created as a result of the failures in risk management evident in the case, was managedThe effectiveness with which the crisis of the Deepwater Horizon platform, created as a result of the failures in risk management is evident in this case. There are six stages of crisis management, including â€Å"avoiding the crisis, preparing to manage the crisis, recognizing the crisis, containing the crisis, resolving the crisis and profiting from the crisis† (Business Risk Management Week 3, 2014, p. 1). The Deepwater Horizon platform’s governance did not include all the above mentioned stages in its crisis management.In the Deepwater Horizon platform, there were serious problems with governance as the Company failed to examine all possible scenarios, assess all possible consequences and identify the cost of prevention of these negative consequences. The response to the crisis was not planned in a proper way. This fact means the BP Company failed to use the appropriate strategies to avoid the crisis. Because of the explosion on the Deepwater Horizon offshore drilling platform, over 5 million barrels of oil were sent into the waters of the Gulf of Mexico.   This fact proves that the company failed to avoid the crisis. According to researchers, the BP oil spill in the Gulf of Mexico is an example of a â€Å"company without crisis planning† (Cox, 2012, p. 87). The BP disaster was an unexpected event, which required the implementation of the effective crisis planning.   According to Charles E. Cox (2012), â€Å"BP’s advantage was that, even without a crisis plan, the company had billions of dollars in the bank and enough cash reserves to manage its way through the crisis and take steps to rebuild its reputation† (p. 88). Undoubtedly, the impact of the BP disaster was enormous because of the lack of the crisis planning.Nevertheless, the BP governance managed to take some reasonably decisive action, using the media and public relations to address the issue of concern and demonstrate the company’s response to the disaster. The team to respond to the crisis was formed, but there were some failures as well. Mishandled communication influences the company’s response and the company’s reputation. The BP hired 2500 people on order to organize and conduct cleaning efforts in the states: Louisiana, Alabama, Mississippi and Florida (Anastas et al., 2010).   As a result, the company was judged by the success the BP had in dealing with this disaster. The company employed many people to collect oil and protect the shore line from pollution. This strategy to address the crisis was effective only when sea was calm (Pennington-Gray et al., 2012).ConclusionThus, it is necessary to conclude that pollution from the activities of offshore companies leads to degradation of the marine environment. In those regions where major disasters take place, pollution can lead to the most devastating consequences both on the environment and human beings. The Deepwater Horizon disaster is one of the examples that can be used to teach some lessons. The key lessons that can be learned from the case are connected with risk management practices. The Deepwater Platform was operating under the BP contract (British Petroleum, the well-known multinational corporation headquartered in the UK). The discharge of oil had negative impact on the region, caused serious damage to fisheries and marine habitants, bringing to light the risk s of deep water oil and gas drilling.The lessons that can be learned from the case give an opportunity to other companies to avoid negative consequences of the crisis and develop, maintain and implement effective crisis management practices. One of the most important strategies to manage crisis is to implement a well-developed crisis plan, provide effective control procedures and risk treatment systems that must be developed and implemented in the areas, where failures occur frequently. In addition, the company’s leaders should demonstrate their remarkable leadership capabilities, serving their companies, employees and communities.

Natural Disasters and the Ancient Sumerians - Essay Example These different legends and myths also involved the data concerning the location and the duration the last great floods are perceived to occur as it is the one that caused the rise and development of these narratives. Even though there is no existing evidence concerning the enormous floods that is believed to have covered almost every mountain in the world, only many narratives from all over the world that is told concerning the great floods which was the major disaster that was faced by the people of Sumerian2. The floods are considered to have destroyed the human race in the unsociable past and which resulted in the map of the world to change in the process. As a result of the floods, the Sumerians were forced to migrate and as a result of this migration, the early Mesopotamia culture was passed to the people where the Sumerians settled3. In the year 5000 BC, the floods of the Caspian Sea and the black sea occurred. The effects of the floods were greatly faced on the northern shores of the sea as in causing the water level of the Mediterranean Sea to rise. This made the red sea to connect itself to the mar Mara Sea that is located next to the modern turkey. The developing pressure that was happening in the earths crust resulted in a region that is considered to be active and of high earthquake magnitude. This is believed to have triggered some of the major earthquakes and some of the volcanic eruptions4. This was also regarded as the great floods as it is explained by the Sumerian legends, which was later hired by the civilization of the ancient Mesopotamia and was eventually recorded down in the bible. The people who managed to escape the floods relocated from these fertile lands to the Western Europe region even though many of the Sumerians went to regions that were warm which is believed to be the southern Mesopotamia region. While in the southern Mesopotamia, the Sumerians found the first humankind civilization and where their

On the other hand, in terms of interests, there were three who are fond of sports; one is into hiking; two loves reading (but on different facets); one loves travelling; two are into volunteer work, and one is into art, as well as modeling. Even other noted information was vastly diverse. Due to the diversity of the group in educational background, line of employment, and interests, the topics that could be of interest to the batch could be current events, especially one that is controversial in nature; or a general topic that could appeal to all: food, health, love, or relationships, to name a few. These suggested topics could be tackled with enough authoritative research and by establishing a thesis statement to determine which point of view or contention one would propose. For instance, a current controversial topic on gun ban or gun control could be a subject of discussion based on the amount of current news articles written on the subject. One could even solicit their respective views on the subject regarding their preference for gun ban or gun control and signify one’s stance. The topic of food could also be interesting in terms of arguing whether American society has manifested a food dilemma in terms of exhibiting increasing trends on obesity despite being health conscious on nutritional contents of the food Americans regularly eat. This topic could also lead to health concerns, especially trying to determine whether advertisements pose more threats for the children in promoting food items that endanger their health. As such, despite the disparities in educational backgrounds, employment experiences, interests or hobbies, and plans for the future, there are different interesting topics that one have thought of which could spur the interest of the class as the potential

Design Experiment Ecology - effect of acid rain on plat growth - Assignment Example These substances are highly toxic to the living world and directly affects plant and other small organisms thereby, indirectly influence the proliferation of other organisms as well. The present study is designed to understand the effect of acid on plant growth. The study requires 2-3 weeks. The amount of acid added to water, for watering the plant is inversely related to the growth of the plant, which is calculated as the height of the plant. Excess of acid adversely affects the physiology of the plant which should be displayed in the form of pigmentation of the plant, more yellow leaves should appear in the plant which is treated with higher acid concentration as compared to the plant treated with less concentration of acid and with tap water. Hence, survival of the plant is directly related to the concentration of the acid given to the plant. The process will also demonstrate the appropriate pH of water required for the plant growth. Make two acidic solutions with two different concentrations, using water and H2SO4. pH is measured with the help of a pH strip. Adjust the pH of one of the solutions as pH = 2 while adjust the pH of the other solution as pH = 4. Pour equal amount of water/ acid solution simultaneously in all the three sets, A, B and C. Plant A should be provided with an acidic solution of pH 2 and plant B should be provided with the acidic solution of pH 4 while plant C should be provided with same amount of tap water. Growth of the plants was monitored and recorded on a regular basis with the help of measuring tape. The experiment continued for two weeks and observations were recorded in the following table for the comparative analysis of the impact of acid on the growth of plants. Control plant, C was watered with tap water and its growth was also recorded in the following table- Acidification of rain-water occurs

Laura Greene SOC 421 Section 1002 Fall 2013 Dr. Mann Marxist Theories in Todays Society Karl Marx was a German philosopher whose work are thought to still have an influence even on todays society. Marx believed that material goods were the root of the social world and that social life is fundamentally about conflict over food, land, money, and other material goods. The ideal government for Marx would be a communist state where resources are equally shared. However, here in America it seems we will always have a democratic government where the rich get richer and the poor get poorer. For my final paper I will use the marxist theoretical ideas to investigate how Wal-Mart uses their economic and financial power to exploit their workers and suppliers. I will use Marx’s theory to understand how Wal-Mart not only manipulates and exploits its employees and suppliers but, also how they are able to alienate their employees. Marx’s theories remain as powerful framework for explaining the actions of a billion dollar multinational company because of its focus Wage-La bor, Surplus Value and Alienation. By sharing with the reader the reasons why Wal-Mart should be considered a threat to our society by using Marx theories, I hope to bring attention the true cost of getting things for a bargain. For the purpose of this paper I will be focusing on his theories about Wage-Labor, Surplus Value and Alienation and using them to explain Wal-Marts actions. Throughout the course of his life, Marx came up with many theories. However, Marx was very interested in the topic of capitalism.nCapitalism can be defined as being an economic and political system in which a country's trade and industry are controlled by private owners for profit, rather than by th... ...ncome. However, today’s materialistic society is so obsessed with the idea of commodity fetishism that we are blinded by the effects of it. We only think of where we can buy great products at low prices? Wal-Mart is always the answer, but if only we knew at what price of exploiting and alienating their employees, would we change out minds. Consumers never see the work that goes into making the product or how the labor has turned the worker into nothing but another commodity. All the consumer sees is the status or wealth depicted by the product. In all capitalism is what keeps our society in order. Even though Wal-Mart has become the bourgeoisie that Marx was against and feared, he would be happy to say that his prediction came true. In all, through these examples, I hope to open the publics eyes and show them at what cost their bargains are costing the workers.

Criminal Law and Procedure Assignment Essay

1) At the Trial of Scissors Lee, the prosecution would like to produce to the court the caution statements of Scissors Lee as evidence of his confession. Can you write out a list of your objections you will raise with the court to the production of the caution statement at the trial? Ans:  Upon the production of the caution statement of Scissors Lee, I would like to raise some objections in term of its arresting procedure, reliability and voluntariness. Arresting Procedure: PC34567 should have cautioned Scissors Lee at the football ground According to the Rules and Direction for the Questioning of Suspects and the Taking of Statements issued by the Secretary for Security in 1992, when PC34567 has evidence that Scissors Lee might have committed an offence, he must caution Scissor Lee before putting him into further questions. In the caution statement, DPC13579 first quoted the conversation between Scissors Lee and PC34567 to induce Scissor Lee to have a consensus in the fact described in that conversation, however that conversation record was not obtained under caution and therefore it should not be mentioned in questioning Scissors Lee. Therefore, the caution statement is not obtained in a proper procedure and should be inadmissible. Arresting Procedure: DPC13579 did not tell Scissors Lee his rights fully under arrest After Scissors Lee was brought to the police station, he was not told by the police that he should have the chance to contact his family or get a lawyer. In that circumstance, Scissors Lee may be put in a situation of helpless and unassisted. Besides, DPC13579 told Scissors Lee that he could only go if he had given him a statement, therefore, there is a reasonable doubt that Scissors Lee may be induced to cooperate to work out the caution statement. If he was told that he may get a lawyer to represent him, he should have stayed silence during the interview of DPC13579. Reliability: The caution statement is recorded in English The interview should be conducted in the mother tongue of Scissors Lee, that seems not to be English but Cantonese, upon the conversation between Lee and PC34567 to avoid any ambiguity and misunderstanding. Scissors Lee is only a Form 4 student at a secondary school and do not do well in academic. Therefore, there is a reasonable doubt that Scissors Lee has the proficiency in English that he understood all the statements made by DPC13579 and stated concisely in his speaking about the whole story of the event. Voluntariness: The length of the time of the interview is too long The duration of the interview is 2 hours. It may be a factor that sapping the free will of Scissors Lee in signing the cautioned statement. When the interview time is lengthened, Scissors Lee was anxious to go home, and there is a reasonable possibility that Scissors Lee just signed the cautioned statement for letting DPC13579 to release him to go home, therefore the cautioned statement may not be made voluntarily and thus should be inadmissible. Voluntariness: Scissors Lee was in hunger but was rejected to take snack Throughout the interview, Scissors Lee was not given any refreshment. The interview was held at the time of having dinner (2000-2200), as he was quite hungry during the interview, he asked DPC13579 for some snack, however DPC13579 ignored him. In such circumstances, it is reasonable to object that the voluntariness of Scissors Lee to sign the cautioned statement was greatly affected by hunger and ignorance of DPC13579, thus the cautioned statement should be inadmissible. Voluntariness: Scissors Lee was deceived in signing the cautioned statement DPC13579 showed the cautioned statement to Scissors Lee, and simply asked him to sign on it without explaining the content. Scissors Lee thought the cautioned statement was a paper stating his right after his arrest and signed on it without full acknowledgement. There is a reasonable possibility that Scissors Lee was deceived into signing the cautioned statement and therefore, he was not voluntary in admitting hitting Ah Ho, therefore the cautioned statement should be void and thus inadmissible. Voluntariness: Scissors Lee was afraid of prejudice in admitting the offence Scissors Lee was told by DPC13579 that he was the only one arrested by the police and he must admit hitting Ah Ho otherwise the police would be very angry and come to his school to see him every day. Scissors Lee was afraid that if he did not admit the offence, the police would really come to see him every day which will obviously cause unexpected harassment to him. Therefore, the cautioned statement is clearly involuntary as it has been obtained by â€Å"a fear of prejudice†. Voluntariness: Scissors Lee was promised in admitting the offence Scissors Lee was told by DPC13579 that hitting is a common assault and he would get away with a fine. Since Scissors Lee thought that he already has a criminal conviction of bound-over and so that one more common assault would not further taint his character. DPC13579 had made an offer of release from police custody and therefore, it is obvious that Scissors Lee signed the cautioned statement in the hope of release, thus that statement is inadmissible. Voluntariness: Scissors Lee was unsuitable for confession upon his emotional status Throughout the interview, Scissors Lee was scared and anxious to go home. Under this mental condition, he was easily affected by external factors, such as the persuasion or threat by DPC13579, impatient to go home; therefore, it appears a reasonable doubt that he admitted the offence in absolute voluntary. As a result, the cautioned statement should not be admissible as it is not fair to demand Scissors Lee to make a comprehensive decision in the interview. Voluntariness: Scissors Lee may be affected by alcohol On the day in question, before PC34567 brought him back to police station, Scissors Lee was forced to drink whisky. It was hard to determine that whether the decision of Scissors Lee was affected by the alcohol. Therefore, there is a reasonable doubt that Scissors Lee signed the cautioned statement in an unconscious status, thus the cautioned statement may not be made in voluntary and so inadmissible. 2) Supposed Scissors Lee would plead guilty at his trial, can you advise him what mitigating factors you should address the court on his behalf? Ans:  After having a detailed analysis in Scissors Lee’s background and the circumstance of the offence, I may address the court some mitigating factors upon the facts of this case and of his background. Case Fact: Scissors Lee was scared of offending Mr. Big Mr. Big was an older boy who started to offer Scissors Lee drinks and snacks and treated him to bar after the match. He taught Scissors Lee how to drink and everybody in the football ground treated Mr. Big like their leader. In this case, Scissors Lee’s offence was instigated by Mr. Big. Mr. Big told Scissors Lee to be at the football ground at 3.30 pm so that he would like Scissors Lee to â€Å"teach Ah Ho a lesson.† Mr. Big continued to threaten Scissors Lee that if he did not come, Mr. Big would treat him naughty and teach him a real nasty lesson. Scissors Lee committed the offence only in fear of Mr. Big but not intentional. Case Fact: Scissors Lee was not the prime mover In this case, Mr. Big was throughout the only prime mover of the offence. Scissors Lee was only in control of Mr. Big because of fear of Mr. Big. He played a less important role than his accomplices in this offence and therefore he should be held less guilty. Without the threat by Mr. Big, there appears no evidence that Scissors Lee would commit the offence and cause any harm to Ah Ho, therefore, Scissors Lee was only a puppet of Mr. Big for his offence to Ah Ho. Case Fact: Scissors Lee attempted to stop others hitting Ah Ho When Ah Egg, Zero, Ah Kin were hitting Ah Ho, Scissors Lee went up and shouted to them to stop. His attempt to stop others hitting Ah Ho shows that, at first, he had no intention of hitting Ah Ho. Scissors Lee only pushed Ah Ho once after Mr. Big yelled at him, the purpose of his offence was only to make a false appearance to Mr. Big that he was hitting Ah Ho but not intended to cause bodily damage to Ah Ho. In such circumstances, his offence was relatively unsubstantial when compared to his accomplices. Case Fact: Scissors Lee was affected by alcohol which was forced to drink by Mr. Big Scissors Lee never like drinking wine. But before the offence, Scissors Lee was forced by Mr. Big to drink a lot of whisky. His offence may be affected by alcohol. Therefore, in such unconscious status, Scissors Lee was partly involuntary to commit the offence. There was no evidence that Scissors Lee will commit similar offence in the future. Case Fact: The injury of Ah Ho was not too serious Ah Ho was sent to the hospital for medical treatment, from his medical report, he was discharged with no complication from his wound and he would be expected to recover fully within two weeks. Although Scissors Lee and his accomplices did damage to Ah Ho, there was no evidence that the offence of Scissors Lee was causing any substantial damage and left any unrecoverable wound to Ah Ho. The offence committed by Scissors Lee was relatively light and it can be seen that the intention of Scissors Lee was not to cause serious harm to Ah Ho. Case Fact: Scissors Lee did not attempt to approach Ah Ho after the offence Scissors Lee has not tried to harass Ah Ho after the event and he stays a distance from Ah Ho, even if they are still in the same class. Scissors had shown genuine remorse for his offence and regret to what he had done to Ah Ho. Base on these circumstances, Scissors Lee is less likely to recommit any offence to Ah Ho. Case Fact: Scissors Lee pleaded guilty in sincere manner and cooperated with the police Scissors Lee was regret for his offence to Ah Ho, and he pleaded guilty in sincere manner. Throughout the arrest, Scissors Lee cooperated with the police and told the fact without any concealment. From the above evidence, we can see that Scissors Lee has the intention to repent and reform, he is less likely to commit any similar offence in the future. Therefore, the court should sentence him in high discretion. Background: Scissors Lee has good relationship with people surrounded From the background report of Scissors Lee, he came to Hong Kong 10 years ago to reunite with his father. However, his father since divorced his mother 8 years ago and left them. Scissors Lee is although come from a complicated family background his relationship with his mother is good. At school, he always has good relationship with school friends, class teacher and the principal. Scissors Lee has good personality and there is no substantial risk of reoffending. Background: Scissors Lee is a person of responsibility Scissors Lee is an active participator at school and he always help the school in important events like open-day, parents-day and whenever Justices of Peace come to visit them. It shows that Scissors Lee has a good character and a good work record at the school. Besides, Scissors Lee is also the sports captain of his school. He is responsible for organizing sport events and taking care of other schoolmates during sport events. All of his achievements at school show that, he is a person of responsibility and therefore he chose to bear the consequence of his offence. Background: Scissors Lee has a clear direction of future career Scissors Lee planned to be a footballer, a dancer or an artist after he has finished Form 5. He has a realistic prospect of career and therefore is outstanding from others of the same age. It shows that he is a mature and thoughtful youngster and therefore the criminal conviction of this minor offence would be a stain in his personality which may substantially affect his career and life in future already. Background: Scissors Lee was not really familiar with the prime mover Mr. Big Scissors Lee was not really familiar with the prime mover Mr. Big and his accomplices, Zero, Ah Kin and Egg. They are only met at the football ground and play football together. After this event, Scissors Lee is much likely to aloof from those people and he will no longer be influenced by these bad friends. Background: Although he was in bind-over, that offence was not relevant to this case Although Scissors Lee has a criminal conviction of fighting in public place on 5 Jan 2009 and he is under bound-over in $1000 for 12 months to be of good behavior and refrain from acts of violence. However, that offence was obviously provoked by the victims and it is not relevant to this case as in this case, Scissors Lee was in threat of Mr. Big. Therefore, the court should not impose any relationship from this record to the present case. Proposed Sentence Since Scissors Lee’s mother who earns only about $8,000 a month is the only financial support in his family, and the maintenance from his divorced father is always received on an irregular basis, to impose a fine may not be suitable as it may cause financial problem to his family. Therefore, a community service order should be imposed as Scissors Lee (1) is one with a light criminal record, (2) has a stable home background and good relationship with his mother, (3) has a good record in school important events, (4) has a realistic prospect of being a footballer, a dancer or an artist, (5) has shown genuine remorse upon his confession and (6) has no more than a slight risk of re-offending upon his background and facts in this case.

Mr. Smith Goes Washington Analysis - 1180 Words

Mr. Smith Goes to Washington Analysis In Frank Capra’s Mr. Smith Goes to Washington, a modern David and Goliath story of a man taking on a system way more powerful than himself is evident in its themes of patriotism and standing up in the face of injustice. James Stewart’s portrayal of a naà ¯ve and patriotic junior senator serves as a vehicle with which Capra exposed a side of American politics that previously had been beyond the eyes of the everyman. With the help of incredible supporting actors, such as Jean Arthur and Claude Rains, Stewart’s character became one of the most well liked and rooted for characters in cinema. The film is â€Å"considered by many to be his greatest achievement in film†www.filmsite.org, and for good reason. Beyond any tangible merits the movie contains, there is a quality of wholesomeness about Smith’s story that is inspirational as it is reminiscent of the modern American dream. 1939 was an important year for such a movie to come out. The second world war had just begun, and patriotic and nationalistic feelings in the United States were growing to what would become an all-time high. Despite the Great Depression causing millions of Americans to question the competency of the government, only a small minority actually saw the government as largely crooked or self-absorbed. Most Americans still had, while not to the degree of the Smith stereotype, a simplistic rule-following perception of Congress.
