Tort Law Essay - Case Study Example It is also necessary for the individual to show that they have suffered damages. The first and critical argument put forward by DURU is that, under the English negligence law, they did not owe a duty of care to Russell. This brings into question the first element of the tort of negligence in that there must be a duty of care before any claim of negligence can be substantiated. The initial notion of duty of care was established in the case of Donoghue v Stevenson1, where it was found that a duty of care should exist, based on the neighbour principle. In this case, a decomposed snail was found in the drinks bottle of the claimant, but there was an argument as to whether or not the manufacturer should be seen as liable, as the claimant had not themselves purchased the bottle. It was found, in this case, that they could be deemed to be negligent and that the claimant would have a claim based on the principle that a duty of care existed to their 'neighbour'. A more modern approach has now been taken by Caparo v Dickman2, where a threefold test was established and it would be this test that DURU would be required to use in forwarding their first defence. In accordance with this case, a threefold test must be passed in order for a duty of care to be established. Therefore, if DURU could show that these are not met, they would rightly be able to rely on the defence that no duty of care existed. The threefold test is as follows: The harm suffered must be deemed 'reasonably foreseeable' as a result of the way in which DURU conducted itself; that there must be a relationship of sufficient proximity between DURU and Russell; and finally that it is 'fair, just and reasonable' for the duty to be imposed on DURU. The test of proximity remains reliant on the test laid out in Donaghue v Stevenson and as stated by Lord Atkin as part of this case. Lord Atkin stated that a duty should be owed to 'persons who are so closely and directly affected by my act that I ought reasonably to have them in contemplation as being so affected'. Other queries have been raised in terms of whether or not it would be reasonable to expect DURU to take some responsibility for the death of Russell. Based on the 2009 Act, DURU has assumed responsibility to provide one to one care in a structured manner to those suffering from drug addiction. In signing Russell up as a patient, a relationship has been established. There is a general concept that there is no positive duty on everyone to undertake certain actions; however, due to the statutory powers given to DURU and the subsequent decision to take Russell on as a client, it is likely to be deemed that a duty of care exists towards Russell, and, for that matter, any other patient taken on by DURU3. Furthermore, the courts are likely to take public policy and interest into account when deciding whether or not a sufficient proximity exists. Based on the underlying reasons for the establishment of DURU and the fact that the organisation has been establis

SWOT - Assignment Example 23). The current situation indicates brand visibility, loyalty, preference and pricing as the main factors that influence choice of the organization. Brand strength is vital in improving the competitive advantage and in turn offset the increasing competition. The approach by the company in the last five years has been the milestone in the establishment of a global brand (Crane & Matten, 2007, p. 102). Despite the positives, the company has several key weaknesses that could lead to serious problem in case of the increase global financial crisis. The company relies heavily on overseas markets which may be affected by the increasing financial crisis and recess. The major opportunity existing in the Asian market is low penetration and improved income levels leading to continuous jumps in the demand for services. This is an opportunity that can be grasped to increase profitability. Additionally, manufacturing units in Europe have huge capacities in line with their vast domestic automobile output. Cross-cultural disharmony is created through the integration of different cultures. The occurrence of disharmony creates a challenge for the corporation and may result in serious problems if not properly solved. Additionally, the rising commodity price is a major threat for the company because it increases the production cost. Holiday packages are developed by tour operators and consist of transport and accommodation that are advertised and sold out as a single item. It may include other services such as car renting. This idea was begun by Thomas Cook in the 19th century. The idea has been used in the tourism sector for several years and is still being used in the promotion of services (Hollensen, 2007, p. 63). Holiday packages should not lead to losses in a business profits. Family packages are rare but provide opportunity for business. The

Rheta Childe Dorr Research Paper Example | Topics and Well Written Essays - 2000 words

Rheta Childe Dorr - Research Paper Example The piece concluded, â€Å"The law of the sea: women and children first. The law of the land—that’s different.†3 However, she is most notes for her books based on her eyewitness reports as a war correspondent making over nine trips to Europe. Her works include, What Eight Million Women Want (1910); Inside the Russian Revolution_ (1917); A Soldier's Mother in France (1918); the autobiography, A Woman of Fifty (1924); and the Life of Susan B. Anthony: The Woman Who Changed the Mind of a Nation (1928). Dorr went beyond fighting for women’s rights in the workplace; she also sought to find equality in the political arena as well. In an extremely critical 1910 argument against sexual biases of the law she wrote her book, What Eight Million Women Want. In this book, Dorr described the political reality of custody law and argued that both men and women should have equal standing in custody of the children. Dorr did not believe women were the only ones who could ca re for the children in defense of joint custody that would allow women to work. She reported that the year before, a bill to equalize guardianship and argued that if wives "had the guardianship of their children, would anything prevent them from taking the children and leaving home? What would become of the sanctity of the home, with its lawful head shorn of his paternal legitimacy. Such contentions stymied legislative reform.†4 In the introduction of this same book, she reiterates this point stating â€Å"They are no longer wholly dependent, economically, intellectually, and spiritually, on a ruling class of men.†5 Dorr argues that child rearing is not a reason for women to stay at home as men also could take responsibility for the raising of the children. What Dorr saw was the inevitable role women would... This research paper discusses the Progressive Era when women were starting to find their voice and break traditional boundaries. The researcher focuses on the discussion of Rheta Childe Dorr, who is most commonly associate with the suffrage movement, but her ethical writings should not be overlooked. Many of her writings as a journalist were directed at women asking them to become involved these social reforms because it was their ethical and moral obligation to get involved. As an example, Rheta Childe Dorr told readers they must insist upon a support system to help the courts deal with juvenile delinquency. "You have established the theory of a court, but you have failed to provide the machinery through which the theory can work." Dorr’s writing was reflective of the typical muckracker style in that she addressed reform issues in the workplace that were published. For example, the researcher describes how Rheta Childe Dorr chose â€Å"Women and Children First† as the title for her 4 May 1912 Woman’s Journal article on the exploitative nature of a Brooklyn sweatshop. However, she is most notes for her books based on her eyewitness reports as a war correspondent making over nine trips to Europe. It is concluded by the researcher that even though she did not receive the recognition she was due during her lifetime, there is no doubt she was influential in the woman’s movement and helped break barriers that would open doors for women who followed in the field of journalism after her.

Pit Bulls Essay Example for Free

Pit Bulls Essay American societies famous bully breeds is too often stereotyped as malicious animals, but that stereotype is false due to evidence that pit bulls can be just as loving as the iconic golden retriever. According to the American Temperament Test, which is a test that focuses on and measures different aspects of temperament such as stability, shyness, aggressiveness, friendliness and self-preservation in the face of a threat shows that Pit Bulls have a temperament of 86.8%, (American Temperament Test Society) a much higher percentage than other breeds which justifies that these animals can withstand a higher tolerance of aggressiveness. If this is the case, why are Pit Bulls one of the most discriminated dog breeds in today’s society? Due to irresponsible owners, Pit Bulls have been labeled cruel and violent animals, leading people to be frightened for themselves, their children, and their pets. By experience and owning a pit bull for oneself, people would begin to understand something entirely different. Pit Bulls are a misunderstood breed; they are one of the most loving and loyal breeds that deserves a fair chance just like any other dog would, but because of irresponsible owners, and their negligence toward teaching their pit bulls the right mannerisms this may never happen. The reputation of the Pit Bull has taken a dramatic downfall in the past few decades due to negative publicity. Originally, Pit Bulls were considered to be   Ã¢â‚¬Å"American darlings†; during WWI they were claimed to be the sweetest and most loving dogs a person could own, but in the 1980’s the view of the â€Å"American darlings† changed due to an illegal â€Å"sport†, dogfighting. Although dogfighting is illegal in all fifty states, inhumane persons who participate in the sport choose pit bulls because of their strong physique and loyal personality, which contribute to the stereotype of all pit bulls being violent due to the public only viewing them as fighters. A famous example of this is the widely known scandal around NFL player Michael Vick, who was convicted of running Pit bull fighting kennels in Smithfield, VA. The outcome of this case brought on more discrimination toward Pit bulls in general. Although Pit Bulls were viewed badly, people still used them as the preferred guard dog not only for the bad as in drug houses and gang members, but also as one would get any dog, to use them as protection for their property. In 1987 an incident regarding a Pit Bull and a two-year-old sent red flags up for this prestigious breed. A pit bull that was under the care of an irresponsible owner had the dog guarding an illegal marijuana crop, in California, when a two-year-old boy who was unsupervised was wandering around and fell victim to the pit bull. This attack was immediately publicized because of the pit bull being involved as the main concern, which made the reputation of Pit Bulls sink even lower. People began to think that Pit Bulls were heartless killers, due to the mis-training of their owners. The public was misinformed; they did not know that the child was wandering around unsupervised in an enclosed area. This situation would create a threat to any guard dog, not just a Pit Bull, and the outcome would have been the same. Because of that horrible mistake, the Pit Bull was killed. In a situation like this, it is in no way the Pit Bull’s fault; he was merely doing his job. Rather, it is the owner’s fault for not clearly training him and the parent’s fault for being careless with their child. This was brought to the courts attention and soon thoughts of a ban against Pit bulls were raised. The public was outraged by this attack and proposed a ban on Pit bulls. This ban was granted throughout 39 or more cities and states without the consent of any animal professionals or the owners of this breed. These bans lead to the death of many innocent Pit Bulls in many areas. Many Cities reportedly spent over two hundred and fifty thousand dollars in rounding up and killing these animals. Devastated owners had their animals confiscated and killed without warning. In Tijeras, New Mexico, the ban was so strictly enforced that animal control officers were allowed to kill any Pit Bull seen on sight without compensation to the owner. Due to their misunderstood reputation, people made rash decisions that affected the lives of many loving Pit Bulls that never stood a chance. They have even become a â€Å"liability† due to their â€Å"overly violent† personalities and because of this have been banned from many areas in the United States. One thing that frightens people the most is a Pit Bulls jaw. While they do have one of the strongest jaws, it is not the strongest. Dr. I. Lerh Brisbin, of the University of Georgia, states, â€Å"The few studies, which have been conducted of the structure of the skulls, mandibles and teeth of Pit Bulls show, that, in proportion to their size, their jaw structure and thus its inferred functional morphology, is no different than that of any [other] breed of dog. There is absolutely not evidence for the existence of any kind of locking mechanism unique to the structure of the jaw and/or teeth of the American Pit Bull Terrier. † There is no evidence to prove that Pit Bulls have unique jaws or any lethal â€Å"lockjaw†. The â€Å"lockjaw† method is learned through training, it is not a special killing tool, and once again the owner creates this issue for the breed. Pit Bulls are not the only kind of dog to be able to do this; most breeds can. The difference is people are already scared of Pit Bulls, so they continue to publicize it much more than the other breeds. Christina Berry, writer for The Lazy Pit Bull states, â€Å"Pit Bulls are the most discriminated dog in the US. This is in part because there are so many myths surrounding them, which makes some people believe theyre not suitable for adoption. This is not true. A rescued Pit Bull can make a wonderful companion. † Once people realize this, then Pit Bull adoption rates will rise and they can be put into good homes. These animals need someone that will take care of them and love them. That is all that is required for a happy dog and no accidents will be encountered. If these animals were provided the rights training and proper care than there would not be any worry about owning one of these animals. There are many precautions that have to be taken when owning these animals. Such as; proper housing and fencing, this contributes to a safe environment where these animals can roam and live without the disturbance of others. Also a calm and secluded area where no one can be around or taunt the animal in its own territory. When these animals are out in the public they should be constantly under supervision, this will allow you to know what the animal is doing at all time and give the proper amount of time to react if the Pit Bull feels threatened. Throughout the awful times many people continue to stand by Pit Bulls, these people are the ones that have experienced owning this loving creature and understand that the bad reputation Pit Bulls have is merely a misconception. I believe that Pit Bulls are the greatest breed a family could have. I have had fourteen Pit Bulls and each one was very special to me. They are very playful, confident, strong, humorous, loving, but most of all loyal. They will do anything for their owners. They are just like any other dog, but unfortunately they are not seen the same. Not one of my Pit Bulls ever harmed or attacked any other animal or human. They continuously proved themselves to being the sweetest animals that many have had the great fortune to meet. What normal, other dogs can do, like jump on somebody or behave like a dog, a Pit Bull can do that and be deemed dangerous, (Kingsbury) Unless people start taking the time to get to know the extraordinary breed that Pit Bulls are, they will never be able to understand their true personality or help them. Pit Bulls need to stop being looked at as monsters and killing machines, they are just like any other dog. They are loving, trusting, loyal, and fun. Pit Bulls are a wonderful versatile breed and are used for many different purposes; Fighting is not the only thing they excel at. They are a breed always focused and determined to please its owner, thus if we start using them for the right purposes these dogs make wonderful therapy, guide, rescue, service, weight pulling, but most of all companion dogs. â€Å"Pit Bulls love people. Although this breed frequently gets a bad rap in the media, if you have ever met a Pit Bull that was raised by a loving, conscientious family then you will understand how much they like to be with people.   All they need is the right kind of guidance, and owner. Pit Bulls are just like any other pet that one takes into their home, these dogs are wrongly named and deceived for the acts they are trained by their owners to do. JRL Solutions states, â€Å"It is in actuality the humans who continue to make a series of hasty or ignorant mistakes that are helping to perpetuate the bad reputation this breed has gained over the last decade. † If a law should pass against these dogs, it should be the law to mandate the right methods of training. To punish these dogs and classify them as malicious or dangerous is a hypocritical judgment as any dog, small, medium, or large could be classified into these categories. After much research and experience as I have had my fair share in taking responsibility and care of this precious breed, it is safe to say that society should rethink their opinions and misconceptions of these dogs. It is proven that they were the â€Å"American darlings† of our time, they have the tolerance to withstand aggressiveness, and they are one of the most loyal companions any man could ask for.

Ofdm Techniques In Satellite Communications

Ofdm Techniques In Satellite Communications The concept of Orthogonal Frequency Division Multiplexing was first proposed in 1960 and developed in the 70s .All bandpass modulation schemes use single carrier by adjusting frequency, phase or amplitude .As Digital transmission uses high Bandwidth (data rates), the duration of bit information becomes smaller. The system becomes more vulnerable to loss of information from impulse noise,signal reflections and other impairments. As the bandwidth used by a single carrier system, the vulnerability to interference from other continuous signal sources become greater. ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING Modulation:-A mapping of the information on changes in the carrier phase, frequency or amplitude or combination. Multiplexing:-Method of sharing a bandwidth with other independent data channels. OFDM is a combination of both multiplexing and modulation. OFDM is a special case of FDM . In OFDM the signal is first split into independent carriers, modulated by data and then re-multiplexed to create a OFDM carrier. This can be done by using different modulation/demodulation techniques. The FDM systems requires a guard band between modulated subcarriers to prevent the spectrum of one subcarrier from interfering with another and not using bandwidth efficiently as in fig(i). If the FDM system uses a set of subcarriers that are orthogonal to each other. The use of orthogonal subcarriers would allow the subcarriers spectra to overlap,thus increasing spectral efficiency. As long as orthogonality is maintained, it is possible to recover the individual subcarriers signals despite their overlapping spectrums. . Fig(1): General representation of an FDM scheme with guard bands. Fig(2): Orthogonal FDM, eliminating the guard bands. OFDM can be implemented using the Discrete Fourier Transform (DFT). The sinusoids of the DFT form an orthogonal basis set, and a signal in the vector space of the DFT can be represented as a linear combination of the orthogonal sinusoids. One view of the DFT is that the transform essentially correlates its input signal with each of the sinusoidal basis functions. The OFDM signal can be a baseband signal or a band pass signal. For wired systems, due to the limited bandwidth of the wires, baseband OFDM signals are transmitted. For wireless communications, such as wireless local area network (WLAN) specified by IEEE 802.11a standard OFDM signal frequency bands are allocated in the RF frequency band. In this case, OFDM signals are generated in baseband first and up-converted to the RF band for transmission. Mathematically, the OFDM signal using the DFT/IDFT pair would be as shown [4]: DFT: X(k)=ÃŽ £n=0to(N-1) x(n) exp(-j2Ï€nk/N) IDFT: x(k)=(1/N) ÃŽ £n=0to(N-1) X(n) exp(j2Ï€nk/N) Figure (3): General block diagram of OFDM MULTIPATH CARRIERS As OFDM uses Multipath carriers they cause two problems Intersymbol Interference:-This occurs when the received OFDM is distorted by the previously transmitted OFDM symbol.Where as in single carrier the interfere is due to several other symbols instead of just the previous symbol. Intersymbol Interference can be removed by using guard interval. Intrasymbol Interference:-This occurs due to the interference amongst a given OFDM symbols own subcarriers. Fig(4): Performance evaluation of various modulation techniques with OFDM OFDM ADVANTAGES AND DISADVANTAGES OFDM offers many advantages over single-carrier modulations [1]: The maximum signaling rate (Nyquist rate) for a given channel can be approached without the use of sharp cutoff filters. It elongates the symbol period so that the signal is more robust against inter symbol interference caused by channel dispersions and multipath interference. It divides the entire frequency band into narrow bands so that it is less sensitive to wide-band impulse noise and fast channel fades. The effect of a slow frequency-selective fade is a separate complex gain on each sub-band signal and it can be removed by simply multiplying the signal by the conjugate of the complex gain-that is, equalization can be easily done by a one-tap equalizer. Different modulation formats and data rates can be used on different subcarriers depending on the noise level of individual sub-bands (the symbol periods are kept the same). In serial transmission, certain types of noise (such as time varying tone interference) may cause an entire system to fail; the parallel OFDM system can avoid this problem by adaptively reducing the data rate of the affected sub-bands or dropping them. OFDM can be implemented digitally using an inverse discrete Fourier transform and discrete Fourier transform (IDFT/DFT) pair (via the efficient fast algorithm IFFT/FFT pair), which greatly reduces the system complexity. OFDM is based on a parallel data transmission scheme that reduces the effect of multipath fading and makes the use of complex equalizers unnecessary. OFDM achieves high spectral efficiency by allowing the sub-carriers to overlap in the frequency domain. The sub-carriers are made orthogonal to each other therefore there is no Inter-Carrier Interference. If the number of sub-carriers in N, the total bandwidth required is BWtotal=(N+1)/Ts. For large values of N, the total bandwidth required can be approximated as BWtotal=(N)/Ts. On the other hand, the bandwidth required for single carrier transmission of the same data is BWtotal=(2N)/Ts. Thus we achieve a spectral gain of nearly 100% in OFDM compared to the single carrier transmission case. OFDM also have DISADVANTAGES over single carrier modulation systems The OFDM signal has a noise like amplitude with a very large dynamic range, therefore it requires RF power amplifiers with a high peak to average power ratio. It is more sensitive to carrier frequency offset and drift than single carrier systems are due to leakage of the DFT. High sensitivity to synchronization errors. Nonlinear effects generated by the power amplifier may introduce inter carrier interference and thus destroy the orthogonality. Larger sidelobes may result in sensitivity to frequency. APPLICATIONS OF OFDM Wireless LAN Applications HIPERLAN/2 HIPERLAN/2 is a Wireless LAN application defined by the ETSI. HIPERLAN/2 handles data rates between 6-54 Mbit/s. HIPERLAN/2 provides a DLC layer on top of which an IP based broadband network can be implemented. The Physical layer of HIPERLAN/2 is based on the Orthogonal Frequency Division Multiplexing (OFDM) modulation scheme. The Numerical Values of OFDM parameters in HIPERLAN are given below: Parameter Value Sampling rate fs=1/T 20 MHz Symbol part duration TU 64*T 3,2  µs Cyclic prefix duration TCP 16*T, 0,8  µs (mandatory); 8*T, 0,4  µs (optional) Symbol interval TS 80*T, 4,0  µs (TU+TCP) ; 72*T, 3,6  µs (TU+TCP) Number of data sub-carriers NSD 48 Number of pilot sub-carriers NSP 4 Sub-carrier spacing à ¯Ã‚ Ã¢â‚¬Å¾f 0.3125 MHz (1/TU) Spacing between the two outmost sub-carriers 16.25 MHz (NST*à ¯Ã‚ Ã¢â‚¬Å¾f) IEEE 802.11 The IEEE 802.11 committee has a standard similar to the HIPERLAN. Its OFDM parameters are as shown below: Data Rate 6,9,12,18,24,36,48,54 Mbps Modulation BPSK, QPSK, 16-QAM, 64 QAM Coding Rate 1/2, 2/3,3/4 No of Sub-Carriers 52 No of pilots 4 OFDM Symbol Duration 4 us Guard Interval 800 ns Sub-Carrier Spacing 312.5 kHz 3 dB bandwidth 16.56 MHz Channel Spacing 20 MHz Satellite Communication applications Digital Audio Broadcasting (DAB) Digital Audio Broadcasting is a new multimedia technology, with a good sound quality and better spectrum efficiency. The DAB system samples audio at a sample rate of 48 kHz and a resolution of 22 bits. Then the data is compressed to between 32 and 384 kbps. A rate  ¼ convolution code is used with constraint length 7. The total data rate is about 2.2 Mbps. The frame time is 24ms. QPSK modulation is performed at the transmitter. The advantage of using OFDM for DAB is that the OFDM suffers very little delay spread and has high spectral efficiency. Digital Video Broadcasting (DVB-T) Digital Video Broadcasting is an ETSI standard for broadcasting Digital Television over satellites, cables and through terrestrial (wireless) transmission. Terrestrial DVB operates in either of 2 modes called 2k and 8k modes with 1705 carriers and 6817 carriers respectively. It uses QPSK, 16-QAM or 64-QAM subcarrier modulations. It also uses pilot subcarrier for recovering amplitude and phase for coherent demodulation The major use of OFDM can be observed when multiple techniques can be transmitted and received at the same time. This can be done with the help of MIMO OFDM. The transmitted signal will be received by various VSAT networks based on the corresponding frequencies. Further, processing of this signal and error corrections, the original signal is retrieved. For example, consider that a DAB, DVB and other geological information is received by various antennas as shown in the figure. NEWEST RESEARCH AND FUTURE TRENDS OF OFDM One of the methods developed in the recent years is that the convolutional coding (CC) and trellis coded modulation (TCM) are combined with OFDM for a Rician fading channel according to the specifications given by the Iridium system. Here, the bit error rate (BER) performance of OFDM with 8-PSK and 16-QAM modulation techniques along with two different coding schemes are considered for a LEO satellite channel. Trellis coded OFDM gives the best performance compared to convolutional coded OFDM. The peak to average power ratio (PAPR) can be reduced approximately by 1.5 dB with the help of the partial transmit sequence technique (PTS). Later, some more research and simulation results proved that the Turbo Coded (TC) OFDM performed better than CC or TCM with OFDM [6]. Satellite mobile systems are developed to provide connectivity between remote terrestrial networks, direct network access, Internet services using fixed or mobile terminals, interactive multimedia applications, and high data-rate transmissions. Most of these research and development scenarios have considered the Non-Geo Stationary Satellite (NGSO) network for providing satellite-based mobile multimedia services because of its low propagation delay and low path loss. As a result, new generations of broadband satellite communication systems are currently being developed to support multimedia and Internet-based applications. For example, the Spaceway system provides downlink transmission rates of up to 100 Mbps, and a total capacity of up to 4.4 Gbps. In order to significantly increase the capacity of 4G broadband satellite systems, current research aims at developing new advanced technologies [5]. In the wireless system, OFDM is the main basis for several television and radio broadcast applications, including the European digital audio broadcasting (DAB) and high-definition TV (HDTV) terrestrial broadcasting as well as North American digital radio broadcasting. By the beginning of the 21st century, OFDM has been adopted as standard for new high-rate wireless local area network (WLAN), such as IEEE 802.11, HIPERLAN II, as well as the Japanese Multimedia Mobile Access Communications (MMAC). Currently, many researches are underway to devolve an OFDM-based system to deliver mobile broadband data service at data rates comparable to those of wired services, such as DSL and cable modems. Moreover, OFDM technology is a very attractive candidate when targeting high quality and high flexibility in mobile multimedia communications over satellite systems [6]. When the research interest is in the integration process of 3G terrestrial systems with the satellite domain, the conventional frequency division MAS (FDMA) system looses its flavor in competing with the code division MAS (CDMA) and time division MAS (TDMA)-based systems for its very high bandwidth (BW) requirement. Moreover, in satellite systems, it is shown that CDMA system outperforms the FDMA system when diversity is taken in to account. In this case, OFDM replaces FDMA with manifold advantages. Currently wideband CDMA (W-CDMA) and OFDM/TDMA techniques are successfully in use in terrestrial mobile multimedia systems. Therefore, these two Multiple Access schemes (MASs) are getting considerable attention [7] in mobile multimedia communications for Non-Geo Stationary Satellite interface.
