Comparative Essay David Hume vs. John Locke - 1050 Words

Comparing John Locke against David Hume : Empiricism John Locke and David Hume, both great empiricist philosophers who radically changed the way people view ideas and how they come about. Although similar in their beliefs, the two have some quite key differences in the way they view empiricism. Locke believed in causality, and used the example of the mental observation of thinking to raise your arm, and then your arm raising, whereas Hume believed that causality is not something that can be known, as a direct experience of cause, cannot be sensed. Locke believed that all knowledge is derived from our senses, which produce impressions on the mind which turn to ideas, whereas Humes believed that all knowledge is derived from experiences,†¦show more content†¦Hume rejected lockes theory of experiencing cause. He argued that you do not feel the connection between your mind and arm, and thus dont sense the cause of the muscles contracting to raise your arm. Cause, in Humes mind, is a synthetic experience used to explain the unobser vable things in reality. To help explain he used the billiard ball experiement. Ball A is hit and put into motion towards ball B.When ball A collides with ball B the cause of ball Bs movement is not experienced, there is no observable connection between the two. This would mean that there is no way to be certain that everytime Ball A collides with ball B that ball B will move, ball A could just as likely bounce off and begin rolling in a random direction. He believd that there is no way of knowing for certain the outcome of an event without being able to perceive the cause. John Lockes theory of knowledge stated that all knowledge is derived from the senses, that are converted into impressions, that are then made into ideas, either simple or complex. Simple ideas are ones that involve only one sense, whereas complex ideas consist of multiple simple ideas being combined to create a vivid one. Ideas have two qualities, primary qualities, and secondary qualities. Primary qualities are things that are perceived the same for everyone, and secondary qualities are the individual perceptions ofShow MoreRelatedCleanth Brookss Essay Irony as a Principle of Structure9125 Words   |  37 PagesHistory and Class Consciousness Preface THE collection and publication of these essays in book form is not intended to give them a greater importance as a whole than would be due to each individually.

Effectiveness of the Criminal Justice System in NSW Free Essays

‘Evaluate the effectiveness of the criminal justice system in NSW’ The NSW criminal justice system relates to all areas associated with the law and law enforcement, including those who are incarcerated, on probation, or suspected of committing a criminal offence. In evaluating the effectiveness of the criminal justice system in NSW there are three issues which can be considered; alternatives to gaol, charge negotiation and the role of the courts. We will write a custom essay sample on Effectiveness of the Criminal Justice System in NSW or any similar topic only for you Order Now These issues promote or demote the effectiveness of the NSW criminal justice system, especially when evaluated in terms of equality, accessibility, resource efficiency, and the balance of rights for victims, offenders and society. These issues are also discussed widely in the media, which presents a different perspective for many of these issues, and provides the necessary pressure required to initiate law reform on these issues. One of the most important issues in the NSW criminal justice system is the availability of alternatives in punishment, aside from incarceration. Apart from criminal infringement notices, there are many more serious alternatives to a prison sentence, including home detention. Home detention, created under the Home Detention Act 1996 (NSW), is applicable for certain offenders, who have committed non-violent crimes and have been sentenced to less than 18 months imprisonment. Home detention is likely to be controversial for more serious offences such as murder or sexual assault, as there is possible high risk of reoffending. Community service orders are also available as a means of shaming and punishing offenders, while facilitating rehabilitation by requiring a period of amending their wrongs towards the community. Diversionary programs are used to divert certain offenders from reoffending, through rehabilitation. Over 150 offenders a year complete The Drug Courts diversionary program. According to the NSW Crime Bureau analysis of the effectiveness of the Drug court, they found that; 37% of criminals were less likely to be reconvicted for any offence, 65% were less likely to be reconvicted for offences against the person and 57% were less likely to be reconvicted for a drug offence. The use of these alternatives are effective in terms of the aforementioned criteria as it provides a sense of equality between different members of society tried for the same crimes, as they each have the capacity to be given the same diversionary program, as long as they satisfy the necessary criteria. The diversionary programs are very resource efficient as they typically cost less per day than the $205 necessary for the average prison inmate. It also provides a balance of rights for the victims and the offenders, as well as society as they are all benefiting from these programs. Charge negotiation, including plea bargaining, is where charges are either dropped, or reduced in return for an early guilty plea, as set out in the Crimes (Sentencing Procedure) Act 1999. There are many issues associated with charge negotiation, as shown through ‘True Plea on Justice’, a Daily Telegraph article published on October 11th 2010, which details the plight of victims of crime, who are not told of the charge negotiation taking place, until they attend the trial. Under new guidelines from the state government, prosecutors must now complete a certificate detailing the consultation with victims and their families. This reform of current guidelines shows the inadequacies when regarding the balance of rights for victims, although this issues is being rectified. Charge negotiation is also effective when assessed for resource efficiency, as the cost of a sometimes lengthy trial is avoided. The role of the courts is imperative to having an effective legal system. The role of the courts is to ensure a fair trial ensues. Equality within the court system is a major concept, and is exemplified through the necessary impartiality of magistrates, judges and juries. Once again to ensure equity judges and magistrates are bound to follow precedent, or follow sentencing guidelines according to the Criminal Procedure Amendment (Sentencing Guidelines) Act 1998. Many of the crimes prosecuted are outlined in the Crimes Act 1900 (NSW), which is accessible to all members of the public, under the rule of law. The courts attempt to use resources efficiently by using juries in all matters bar summary offences, and by requiring ‘leave to seek appeal’ when appealing to the Supreme Court to ensure that court resources are not tied up in unsubstantiated appeals. The courts also provide a balance for victims, offenders and society, by providing necessary sentences the magistrate or judge feels is necessary to reflect the standards of society, ensure a fair outcome for victims and also to not be excessive to offenders. The criminal justice system in NSW is effective in the sense that it provides an equal, accessible and resource efficient system in which justice is achieved. It also provides an impartial field for offenders to be tried, and as such come to outcomes that benefit the victim and society as a whole. There have been recent developments to ensure this balance remains, as is the case of victims regarding charge negotiation, showing the development and thus effectiveness of the criminal justice system in reflecting societies beliefs and values.

Visible Light Communication

Question: Describe about the Visible Light Communication? Answer: Introduction Visible Light Communication (VLC) falls in the category of the highly developed technology of the optical wireless communication division, in this visible region (0.375um-0.780um) light is utilized as a data transmission medium with enhanced security and higher data rates features in comparison to the predictable technologies similar to Wi -Fi, Wi-max etc., which accomplish the communication by the radio waves. While making use of wireless internet the system bandwidth got bothered at the lower data rate or slow speeds frequently in the case of multiple devices using the same network. To conquer the lack of bandwidth we can make use of light for data transfer and the process is called as ILLUMINATION DATA . The thought at the back is that, infra-red remote is somewhat customized i.e., LED light bulb that bring intensity contrasts which cannot be tracked by normal human perception. It is probable to encode the data in the light by modulating or altering the light to make the LEDs flic ker and make it on and off to provide the binary strings of 1s and 0s.At the same time as using combinations of green, blue and red LEDs to change the frequency of light encoding a dissimilar data channel. System Components It utilizes fast changing light pulses to send out the information wirelessly. The major parts of this system of communication are A high intensity white LED, that is the source of communication A photodiode is made up silicon having high-quality visible wavelength response region which is acting like the receiving element. Amit rawat Switching the LED in the on and off mode is done to produce binary 1s and 0s strings. Encoding of data can be performed in the light to produce a novel stream of data by changing the LED flickering rate. To be precise, through the process is about modulation of the data signal using the LED light, the illumination of the LED light can be utilized like a source of communication. Due to the fast flickering rate, the output at the LED end comes into view like a constant light to the naked eye. Using suitable techniques for multiplexing it is possible to have data rate more than 100 Mbps. In case of parallel data communication the VLC data rate can be augmented. In this each LED transmits a dissimilar data stream and combined forms an array. LED Model Fig. 1 demonstrates the standard demonstrator block diagram. The link contains of two DSP boards first one is transmitter (Tx) and second is the receiver (Rx). In exacting, the evaluation board of TMS320C6000 DSP using Texas Instruments C6713 based on floating-point processor that is structured of VLIW very long instruction word architecture is utilized. Speed of processor is 250MHz. The evaluation boards has 32-bit stereo analogue output and input port with a utmost sampling frequency 96kHz. Fig.1 Visible light data transmission prototype For the function of exhibition, data source of digital image is utilized. The produced D/A (digital/analogue) changed modulation signal from the correspondent DSP is feeder to the circuit of optical transmitter which constrains the white LED. At the end of receiver, a circuit containing a photodiode is utilized to change the signal of optical range to the signal of electrical domain. The converted signal is then conceded through an ADC converter trailed by elimination of cyclic prefix and process of demodulation. These processes are headed by a frame synchronization routine Fig.2 VLC test-bed system using an array of 16 resonated white LEDs. Concept Illustration The VLC transmitter has components like a power supply, an amplifier, a bias-T. The receiver includes a PIN type diode as a photo-detector or APD or Avalanche Photo Diode. LED acting as a source of light from the transmitter side produces visible light radiation and then absorbed by the receiver all the way through free space spread. The signal source and a terminal analyzer component is made up of two-port network analyzer, giving output in form of a small sine wave and calculating the received amplitude too. The LED modulation bandwidth is limited with the frequency of response. Though, the lifetime of the minority carriers in semiconductors have an effect on this reaction frequency. Consequently, there exists a limit on the LEDs theoretical bandwidth upto 2 GHz. at present; the practical LED bandwidth is much lower than this limit of theoretical value. Therefore, the resulting LEDs lower modulation bandwidth influences its function in the communication with the high-speed bandwidth. Results and Discussion For analysis consider the three different LEDs which are further separated into three categories, which were calculated using same intensity of light, and after that the only variable is the current density. Consequently, the consequences can straightly replicate the association of the 3 dB LED bandwidth and current density. In below Figure 3, the Y coordinates gives amplitude, tells that the proportion of power at output and power at input and it reproduces the LEDs 3 dB bandwidth. Since noise is present in the background the curvature in Figure 3 shows big fluctuations. Although, these curves with non-smooth nature does not moving the in general experimental results trends. As given in figure 3 that the LED As 3 dB bandwidth was 10.5MHz if the biasing current is 20 mA and the significance quickly increased to value of 44MHz for the biasing current of 100mA. In adding, the other LEDs B and C also established this regulation and the consequences were revealed in Figures 3(b) and (c), correspondingly. Consequently, the calculated 3dB bandwidth of three dissimilar sizes LEDs were all enhanced considerably with the amplified current density. This occurrence can be established with the probability of bimolecular recombination, that was relative to the carrier density of injected into the dynamic volume. Fig. 3 The normalized frequency response of (a) LED A, (b) LED B and (c) LED C measured under different bias currents Summary and Conclusions In this report, a dimension association of modulation individuality for VLC systems is explained and the dissimilar-sized blue LEDs with different bandwidths have been accounted. The results obviously discloses alike linear association between 3dB bandwidth and its LED current density. This occurrence can be credited to the bimolecular recombination likelihood that is relative to the density of injected carrier into the dynamic volume. Consequently, growing the LED current density is a possible method in VLC systems to improve the rate of data transmission. Furthermore, this experiment demonstrates that series resistance of high value is one main concern that puts restriction on modulation speed of LED. Therefore, additional study will spotlight on optimizing layout of device in addition to dropping material bulk resistance to decrease the resistance. References 1. H.L. Minh, D. OBrien, G.

Arts in Schools Essay

Arts in Schools Essay Arts in Schools Essay A child’s education cannot rely on reading and math alone. A wide range of educational opportunities need to be made available to a child to allow them to explore their talents and interests, whether it be through arts programs, athletics programs, or other activities outside of subjects on standardized tests. Not every student wants to be an engineer or scientist and those children should not be denied opportunities in their education. Creativity in the classroom plays a big role in how children involve themselves in their studies, social lives, and home lives. It is an important part of education and should be valued more. Many people believe that the arts are a waste of time and aren’t going to land you a stable job in the future. What they don’t realize is that having knowledge in different arts, benefits students in different parts of their lives. Including in the classroom where they learn math and science. Not only does having knowledge in the arts stimula te and develop the imagination and critical thinking, but it also refines cognitive and creative skills. Whilst other students might solve a problem based solely on logic, students with a knowledge in the arts can look at that same problem both logistically, and creatively providing them with more insight on the problem. Arts knowledge also has a tremendous impact on the developmental growth of every child, and has proven to help level the learning field across socio-economic boundaries. It strengthens problem-solving and critical-thinking skills, adds to overall academic achievement and school success. When a student is involved in artistic thinking, it truly teaches them life skills, such as developing an informed perception, articulating a vision, learning to solve problems, and make decisions. Not only this, but it also aids in building self-confidence and self-discipline, developing the ability to imagine what might be, and accepting responsibility to complete tasks from start to finish. Being in any type of arts program, whether it’s acting, or dancing, film, or general art, self-confidence and self-discipline are strongly provided. With open arms, art programs accept any student that might be having a hard time in school, or at home, and gives them something to be proud of. Whether it be a painting they painted or performing in the school play, being in an art program lets you use your passion and soul to make or do something that you are proud of. By painting, training, or practicing hard, the student achieves their goal using self-discipline for in the arts, you can only be as good as you yourself try. Art programs throughout the world give any students the right to speak what is on their minds and in their hearts and to not be judged, but praised for it. Creativity, soul, heart, passion, hard-work are just some examples of what the arts can give back to you. Having art programs in schools is essential. A very intelligent man named Ken Robinso n made a delightful speech regarding art programs in schools on the website TED.com. Besides being British and hilarious, he makes substantial points and tells such wonderful funny stories! An influential quote from his speech is "If you're not prepared to be wrong, you're not going to come up with anything original." This is quite a true statement. He isn't saying that being creative necessarily means that you are wrong. He is just saying that when being creative, you're willing to take the chance and not care about the results, your answer will be genuine and unique. One extraordinary point he makes in the speech is that as we grow older we are being "educated out of our creativity†. As we go through school we quickly learn that mistakes are terrible, and strive for perfection. Memorizing facts, knowing systems and orders, but what happened to the creativity we had as kids? One last point that he makes, might not be completely true, but is funny and did make some sense. â₠¬Å"Public education is made for making

Do innovations really make us lazier Essay Example | Topics and Well Written Essays - 250 words

Do innovations really make us lazier - Essay Example Certainly, vehicles and other means of transport are inevitable in the current world; however, their discovery has greatly contributed to laziness. Humans are too much dependent on vehicles and bicycles, they go to sporting events, go to work, shopping and market through vehicles. Because of the changes, innovation has led to lifestyle diseases such as high blood pressure and obesity, hence a significant deterioration of the physical health (Anthony, 2012). In the education sector, students no longer get the full benefit and experience of expediting ignorance. Instead, computers, mobile phones and internet have replaced the role of students in learning. Computers have literally eliminated the ability of learners to spell words correctly and engage teachers in different subjects. Gradually, students are forgetting the role of hard work, but rely on the discretion of innovation to handle all problems. The on-going process seeks appliances that make hair, cook, wash, teach and facilitate security (Koschatzky, Kulicke & Zenker, 2001). Therefore, instead of technology making life easy and solving life challenges, it continues to make people

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

Water - Research Paper Example of local divide administration on the quality and quantity of water resource to manipulation of climate change in participation outline on local and international scale (Mays & Larry, 49) Water is considered as an essential commodity in our day to day life. Water is usually found as ground water or even surface water (Moran, Edward & Devin, 19). In this paper I will examine more on ground water. I will also examine factors leading to shortages of water and ways to curb such incidences (Reston & Va, 206). In any given nation ground water comes out as really an essential component. Today, ground water resources, supply water to the surface and surface water sources. Ground water in its highest percentage of about 25% is usually stored as fresh water while only about 1% of the total fresh water is stored as surface water in rivers, dams, lakes and soil moisture (Moran, Edward & Devin, 29). The remaining percentage of fresh water about 74% is usually stored as polar ice and glaciers (Mays & Larry, 48). The fact that ground water is not stored means that this resource is usually not taken into consideration most of the time or even misunderstood. Its presence was appreciated after a research on ground water movement ‘secret’ and ‘occult’ was carried out by Ohio courts (Mays & Larry, 78) This resource is very important to public health, the ecology and more so to the economy at large. Often about 75% of the society’s water system depends on ground water. In addition, rural areas and metropolitan regions in the United States highly depend on the ground water system in all their operations and day to day activities (Moran, Edward & Devin, 48). It is through the availability of ground water that we have the surface water due to the fact that ground water supplies the rivers, streams, dams and lakes during drought seasons or even low flows (Reston & Va, 218). The agricultural sector cannot be left behind too as it plays a very significant role in its use
