Jane's Asylum Research - Essay Example Jane does not wish to do this because her father is abusive to her. She wishes to remain a resident of the U.S., and her uncle in California will become her legal guardian. In order for this to occur, a petition for asylum will need to be filed. While we know that this is the course of action that needs to be taken, there are some present issues that need to be addressed. First, there is the issue of how the petition will need to be filed. According to the Department of justice and other reliable sources, only the parent can file the petition (2002; the City University of New York, 2008; Migration & Refugee Services, 2010). Then, there is the issue of whether or not her uncle can serve as her legal guardian, as refugees under the age of twenty-one are still considered to be children (Refugee Info, 2010; Immihelp ®.com, 1999-2010). Finally, there is the issue of misrepresentation. If a case involving an immigrant is misrepresented, there will be severe consequences for the misrepresentation (Honore, 2005; U.S. Department of State Foreign Affairs, 2009). To be sure that we carefully address each of these issues, a thorough research plan will need to be put into place, making sure that each issue is given careful considerati on. This will be done in the following ways: www.refugeeinfo.org Being that this site is devoted to helping refugees, this will be an excellent resource, since Jane is considered to be a refugee and will need to follow the same process that refugee’s do, in order for her to continue to reside in the U.S. legally. Jane’s rights will only be best defended if we have the proper information about the laws regarding the petition of asylum, as well as concerning the proper processes that will need to be followed. Because knowledge is power, it is important that we have as much of it as possible to insure success of this case. Such knowledge can

Free Space Optical Communication Essay Free space optical communication is the most growing communication because it is easy to install and has a high speed because the signal is transmitted in the air. So that will introduce the atmospheric affect in the optical wave propagation. Atmospheric turbulence causes fluctuations in both the intensity and the phase of the received signal. So we need to study the effect and the limitation if we introduce a free space optical communication system with dual wavelength (980 nm, 1550 nm). Also studying the effect of turbulence when using two different wavelengths. Introduction Free space optical communication is a kind of communication that use light propagation to send data between two points. Free Space Optics are capable of up to 2.5 Gbps of data, voice and video communications through the air, allowing optical connectivity without requiring fiber-optic cable or securing spectrum licenses. So we can use LED’s or Laser for transmission data. Free Space Optics (FSO) technology is relatively simple. Its built on a laser transmitter and a receiver to provide full duplex capability. Each FSO unit uses a high-power optical source, a lens that transmits light through the atmosphere to another lens receiving the information. The receiving lens connects to a high-sensitivity receiver via optical fiber. Because the transmission in occurred in air it is easily upgradable. FSO send a light beam from one point to another using low power lasers in the teraHertz spectrum. This beam is transmitted by laser light focused on photon detector receivers. These receivers collect the photon stream and transmit digital data. If there is a clear line between the two point FSO can operate on a distance of several kilometers as long we have a powerful transmitter. Features of the laser communications system Information usually in the form of digital data, data is entered to be regulated by the laser source transmitting electronics. Coding techniques can be used directly or indirectly depending on the type of laser used. Output source passes through the optical system in the channel. The visual system usually involves the transfer, beam shaping, and the telescope optics. Beam receiver comes in through the optical system and passed to the detection and signal processing electronics. There is also a terminal control electronics that must manage gimbals guidelines and other mechanisms, and machinery, to maintain and track the acquisition of the operating system designed in the mass of the process. In order to communicate, you must have received enough energy by the detector to distinguish signal from noise. Laser power, optical transmission system losses, pointing out shortcomings of the system, transmitter and receiver antenna gains and losses, receiver, receiver and loss tracking, are all factors that force in the establishment of the receiver power. The required optical power is determined by data rate, detector sensitivity, configuration modes, noise, and detection methods. When the receiver is to detect the signals, it is in fact the decision-making regarding the nature of the signal (digital signal is sent when the distinction between the ones and zeros). There are two types of distributions: one when the signal present (including the amount of photocurrent due to the background and the current detector in the dark), and one when there is no signal present (including sources of no signal current only). A threshold must be developed to increase the success rate and reduces the error rate. Even when there is no signal present, the fluctuation sources of no signal lead periodically to the threshold to be exceeded. This is an error stating that the signal exists when there is no signal present. Distribution of signal may also fall on the other side of the threshold, so any errors stating that the signal is going to happen even when the signal is present. Security FSO systems work in the near infrared wavelength range slightly above the visible spectrum. So, the human eye cannot clearly see the transmission beam. The wavelength range is around 1 micrometer that is used in FSO transmission. The interception of FSO operating systems with narrow beam in the infrared spectral wavelength is by far the more difficult. Small diameter of the beam is usually only a few meters in diameter in the target site are one of the reasons that make it extremely difficult to intercept the communications of the FSO. Intruder must know the exact origin or target of the infrared beam and intercept only within a very narrow angle of beam propagation. Intercept packets directly from the FSO networks between remote locations is impossible mainly because the beam passes through the air usually at a higher altitude than at ground level. Due to the fact that the transmission beam is not visible, and that any attempts to block the beam can occur near the FSO point of acces s and the process of transition poses another obstacle. Capture the signal from the location that does not fall directly within the path of light with photons of light scattered from aerosols, fog, rain, or molecules that may be present in the atmosphere is almost impossible because of the energy levels are very low use infrared through FSO process transmission. The main reason for the exclusion of this possibility of intrusion is the fact that light is an ally and statistically isotropic in different directions from the path of the original propagation. This specific mechanism keeps the total number of photons or the amount of radiation that can potentially be collected on the detector that is not placed directly in the beam path beyond the detection level of noise. Atmospheric turbulence Atmospheric turbulence can destroy the performance of FSO systems. The changes in temperature and pressure in the atmosphere lead to changes of the refractive index along the transmission path. These changes can make the quality of received signal fade and causes fluctuations in the intensity and the phase of the received signal. These fluctuations can limit the performance of the system. The atmosphere is a viscous fluid and it has two state motions: 1) laminar (there is no mixing in the air molecules) 2) turbulent: (there is mixing that creates eddies). Atmospheric turbulence can be physically described by Kolmogorov theory. The energy of large eddies is redistributed without loss to eddies of decreasing size until finally dissipated by viscosity. The size of turbulence eddies normally ranges from a few millimeters to a few meters, denoted as the inner scale and the outer scale, respectively. So the index of refraction n is very sensitive to small scale temperature fluctuations (te mperature fluctuations are combined with turbulent mixing). So, the index of refraction is the most important in optical wave propagation. Because it behaves like a passive additive. So the spectrum of index of refraction can be described by Kolmogorove spectrum ÃŽ ¦n (ÃŽ º) = 0.033 Cn 2 ÃŽ º-11/3 , 1/L0 ÃŽ º 1/l0 Here in this model the variations in humidity and pressure are neglected. This model is the most model used in theoretical analyses but it is right only over wave number within the inertial subrange. To take into account the inner and outer scale effects, there is various models have been developed. Like Tatarskii and van Karman models. So all these models are useful for theoretical calculations but only inside the inertial range. They are not based on rigorous calculations outside the inertial range, but more on mathematical convenience and tractability. The modified atmospheric spectrum is the only model that features the high wave number rise prior to the dissipation range. ÃŽ ¦n (ÃŽ º) = 0.033 Cn 2 [1+1.802(ÃŽ º/ÃŽ ºl)-.254(ÃŽ º/ÃŽ ºl)7/6] x exp(-ÃŽ º2/ÃŽ º2 l)/(ÃŽ º2 + ÃŽ º20)11/6 , 0= ÃŽ º ∞ , ÃŽ ºl=3.3/l0 Experiment The experiment that we need to do is to use two laser sources with different wavelength (980 , 1550) and set the receivers about 2-4 km from the transmitter and start sending the signals. We will use the same signals in both transmitters. Then we will study the performance of the system and see if that help to receive the signal in more accurate way than using one transmitter. That will help us to see the effect of optical turbulence and atmospheric effects. So we will calculate the performance of the system and measure the atmospheric turbulence. So we need to ask some questions: What is the effect of optical turbulence? Is losing a part of one signal will be recovered by the other signal? Is that going to help the performance of the system? Is the pdf that we used in the transmitter side will be the same as the pdf in the receiver side?

John Locke and Terrorism :: Philosophy of Terrorism Essays

In 1689, A Letter Concerning Toleration, written by John Locke during his self-imposed exile to his friend Philip von Limborch, was published without the author's knowledge. The Letter concerned religious intolerance. It essentially made the case for religious toleration on the basis of philosophical principles. Locke was concerned with the State's toleration of those not subscribing to the orthodox religion of the day and, by putting a high value on the preservation of negative liberty, he proposed the toleration of a wide range of religious beliefs. His view was at odds with the existing view of the State which, at that time tolerated one, and only one, orthodox belief. But Locke's Letter is not simply applicable to just the 17th Century. The strength and reasonableness of his arguments mean that, even today, they are convincing. I intend to show that The Letter can reasonably be interpreted to reveal how at least two of Locke's three arguments can apply to the religious fundamenta lists who attacked the Twin Towers on September 11th 2001. The perpetrators of that violent incident probably believed the Quran supported the view that, to die whilst killing 'infidels' would punish the wrongdoers and also ensure entry to paradise. But James Rachel in his essay, Ethics and the Bible, has a differing view: "Islamic fundamentalists quote the Quran to justify Holy War against the West, but what does the Quran really say? Mohammed Atta, who led the September 11th attack on the World Trade Centre, left behind four pages of instructions to his men, which included 21 quotations from the Quran. Most of the quotations were exhortations to patience, promises of eternal life, and the like. As for justifying the attack itself, here are the three most belligerent passages: 'And the only thing they Lord, forgive our sins and excesses and make our feet steadfast and give us victory over the infidels.' 'Strike above the neck, and strike at all their extremities.' 'Oh Lord, pour your patience upon us and make our feet steadfast and give us victory over the infidels.'" He also added: "It is remarkable that this was the best the terrorist could do; a Christian would have no trouble producing much more warlike passages from the Old Testament" ThinkIssue One, p. 95 Radical Moslems would be well advised to pause and reflect upon their fundamentalist views which, besides being irrational, are reductio ad absurdum.

Reflections Theory

Reflections theory Introduction In this report I will be comparing two reflective theories, outlining their similarities and differences. I will be choosing the one I believe to be the best in my opinion. This will be the one I will be using in my end of year reflective account. The two reflective theories I will be looking at are, Johns Model of Structured Reflection and Gibbs’s Reflective Cycle. Theories There are two main differences between the two theories. Johns uses a linear structure, with a beginning and an end.However, Gibbs uses a more cyclic structure and has no defined beginning or end. John’s theory is also mainly aimed towards health care and talks about working with patients and their families. Gibbs on the other hand can be aimed more towards students and their experiences. Johns uses the 2 main headings: Looking in and looking out. Under Looking in there are 5 Sub-Headings: Aesthetics, Personal, Ethics, Empirics and Reflexivity. Johns for the most part requires the need to work with a supervisor and as such he calls this a guided reflection.It requires you to write a description of the experience before you begin the reflection, once you have done this it requires you to follow the questions as they come up. One of the advantage of Johns reflective model is that there is a clear Beginning and an end meaning the person looking back on their experience has a clear outline on where to begin and the process used in the reflection. However the issue with the reflexive pattern of knowing is that it will only be relevant for a situation that has been resolved.If your were trying to analyze a situation that’s was ongoing you would have to incorporate parts of another reflective model to help you. With Johns model of structured reflection you would not have to use all the questions within the model, but you could also use the questions a number of times if appropriate. Gibbs Reflective Model is easier to be used by students as it t alks about getting a clear understanding the situations. It uses the six main Headings: Description, Feelings, Evaluation, Analysis, Conclusion and Action Plan.It uses these heading to gain a clear understanding of what went on, what was the experience like for the person, how they interpreted the situation, what they could have done and what they would do again if the situation arose again. Because there is no defined structure and no definite beginning or end, there is the advantage that if the person going through the reflection of their experience and they look back on it they can add more information to each section as and when they think of it, so they can go back or forward to one of the headings and add in the information into the specific field.For example if they feel they need to talk about their feeling first they can do that or if they feel they need to evaluate the situation or talk about what they would do again, and add their input to it, as they can go through the c ycle as many times as they need to get all the information down. Gibbs also talks about what would we do different if the situation arose again. They both put great emphasis on the feelings and the emotions of the person throughout the reflection process. They both talk about what happened and try to make sense of the situation. They both also talk about ConclusionTo conclude the theory that I will be choosing for my reflective practice at the end of year is, Gibbs Reflective Cycle. I have chosen this reflective model for a number of reasons. I believe that Gibbs reflective cycle is more aimed towards Student whereas Johns is aimed more towards health care and talks about working with patients and their families. Gibbs reflective model is also easier to interpret and I believe it to be easier to use to analyze any given situation with the main headings it uses to gain information about the situation the feelings of the person and the experience the person underwent during any given situation.I believe it is easier to follow than Johns model of structured reflection. Gibbs reflective cycle does not require the need of a supervisor to aid the reflection whereas; John’s model talks about have one present to go through the reflection process. I will be using Gibbs Reflective cycle as I feel that it is more relevant to myself and it is clearer to follow and would be easier to use for my reflection process.

Rampant Violent Crime Essay

Since my opponent didn’t give any arguments, I’ll first my arguments: 1.Violence was always there. It’s not a new invention. Since the beginning of time, there has been violence. The first murder is mentioned in the bible. Much before there was even electricity. 2.If the violence you see on television causes you to act violently, each and every one of us (since most of us watch TV) would have been violent 3.Those who act violently are people which are naturally violent. The proof of that is that animals act violently too. animals do not watch TV. They act violently since they are naturally violent creatures. see more:solutions to crime People don’t like to look to themselves when we think about our faults so we turn to a inanimate Scapegoat. While Television has violent programs, it is our decision whether or not to act on what we see or what we allow our children to watch. To blame tv is irresponsible, not taking responsibility to yourself. Virtually everyone in our society watches television, yet we don’t have rampant violent crime rates. Violence existed long before the television and violent crime rates have actually dropped over time. That alone should invalidate any claim of a direct causal relationship. Unless you want to suggest that violence would be virtually non-existent if we had no entertainment, in which case you’re being intentionally obtuse. What television show people have been watching for the last thousands of years? People have been killing people and committing crimes since the beginning of time. I ask an opponent to find one source linking TV to violence directly. Societies with TY’s and societies without TV’s have crime. Television was the scapegoat formed by the old thesis before the antithesis could roll it over. There is no distinction between right and wrong anymore. I see kids crying in the grocery store all the time, and their parents give them candy. For crying! They associate bad behavior with getting what they want. People who are used to getting what they want will become more aggressive. Teaching right from wrong early on will help with the situation, but it first lies with the parenting. After that, the school system needs to pick up on it. Television is entertainment. And it’s not the same with video games where people can argue that video games might make dumb kids think it’s ok to kill people. Most TV shows that have violence show what a bad thing it is, like the guilt and pain that can come from crime. Television has less connection to violence than paintball does to writer’s block. It is the things the people watch on television that influences them. If they watch an action movie and it doesnt have much friction (the bad guy being caught) the viewers might think â€Å"I could do this!† and get an idea of violent actions. In conclusion,it all depends on the show or movie somebody watches and that type of person. Television cannot cause any actions. Yes, we are influenced by our media. But I’ve watched plenty of action-packed gory movies about fights and violence and never had the urge. Part of it is parents, part of it is schooling and local environment. Violence has existed long before the media and although the scope of it has changed, the causes could never be attributed to media. I can’t agree with my opponent that Television is the leading cause of violence in today’s society. Since my opponent didn’t give any arguments, I’ll first my arguments: 1. Violence was always there. It’s not a new invention. Since the beginning of time, there has been violence. The first murder is mentioned in the bible. Much before there was even electricity. 2. If the violence you see on television causes you to act violently, each and every one of us (since most of us watch TV) would have been violent 3. Those who act violently are people which are naturally violent. The proof of that is that animals act violently too. animals do not watch TV. They act violently since they are naturally violent creatures.

In Spoken French, the Ne in Negatives May Be Dropped

In Spoken French, the Ne in Negatives May Be Dropped French negation can be tricky. Normally, to make a statement negative you need to surround the conjugated verb with the formal French negative adverb  ne...pas. However, if youve ever watched French movies or television, or chatted with native speakers, you have almost certainly heard pas (or another negative adverb) used without ne, because this is a typical construction, characteristic of informal and familiar French. Although  the full express  (ne...pas)  is nearly always written out, the ne  is often dropped in spoken French. But  you should be able to construct a sentence, in most cases, using the full ne...pas  that means the same thing.  Pas  without  ne can be used to negate adjectives, adverbs, nouns, pronouns, and verbs.   Purists will tell you that using pas without ne  is wrong (and they tell me I shouldnt teach it), but the reality is that this is how the French speak now.  So if your goal is to sound more French, thats how you should speak, too. Informal Negative Statements Without Ne Je ne sais pas. Je sais pas.  Or even:  Jsais pas,  Sais pas,  and  Chais pas (pronounced  Shai pah). (I dont know.)  Il ne va pas venir. Il va pas venir. (He isnt going to come.)Elle nest pas encore arrivà ©e. Elle est pas encore arrivà ©e. (She hasnt arrived yet.)Ne bouge pas  ! Bouge pas  ! (Dont move!)Il ne faut pas faire à §a  ! Il faut pas faire à §a. (You shouldnt do that!Note: Its not just  ne...pas  constructions where speakers drop the ne; they do as well with all the other negative structures.Je nai plus dargent Jai plus dargent. (I dont have any more money.)Nous ne le voyons jamais Nous le voyons jamais. (We never see him.)Je nai aucune idà ©e Jai aucune idà ©e. (I have no idea.)Je nen sais rien Jen sais rien. (I dont know anything about it.)

A Brief History of the Tampon and Who Invented It

A Brief History of the Tampon and Who Invented It The first tampons were made using a wide variety of materials found in nature. The prevailing thought seemed to be that if it was absorbent, chances are that it would work as a tampon.   Tampons First Appeared in Ancient Egypt For instance, the earliest historical evidence of tampon use can be found in ancient Egyptian medical records that described tampons comprised of material derived from the papyrus plant. In the fifth century B.C., Greek women fashioned their protection by wrapping lint around a small piece of wood, according to writings of Hippocrates, a physician considered to be the father of western medicine. The Romans, meanwhile, used wool. Other materials have included paper, vegetable fibers, sponges, grass and cotton.   But it wasn’t until 1929 that a physician named Dr. Earle Haas patented and invented the modern-day tampon (with applicator). He came up with the idea during a trip to California, where a friend told him how she was able to improvise a more comfortable and effective alternative to the commonly used and bulky external pads by simply inserting a piece of sponge on the inside, rather than outside. At the time, doctors were using plugs of cotton to staunch  secretions and so he suspected a compressed form of cotton would absorb just as well.   After a bit of experimenting, he settled on a design that featured a tightly bound strip of absorbent cotton attached to a string to  allow for easy removal. To keep the tampon clean, the cotton came with an applicator tube that extended to push the cotton into place without the user having to touch it. Tampax and o.b.: Two Brands With Longevity Haas filed for his first tampon patent on November 19, 1931, and originally described it as  a catamenial device, a term derived from the Greek word for monthly. The product name â€Å"Tampax,† which originated from â€Å"tampon† and â€Å"vaginal packs,† was also trademarked and later sold to  businesswoman Gertrude Tendrich  for $32,000. She  would go on to form the Tampax company and begin mass production. Within a few years, the Tampax arrived on store shelves and by 1949 appeared in more than 50 magazines.   Another similar and popular type of disposable tampon is the o.b. Tampon. Invented by German gynecologist Dr. Judith Esser-Mittag in the 1940s, the o.b. Tampon was marketed as a â€Å"smarter† alternative to applicator tampons by emphasizing greater comfort and doing away with the need for an applicator. The tampon comes in the shape of a compressed, insertable pad designed to expand in all directions for better coverage and also features a concave tip so that a finger can be used to push it snugly into place.   In the late 1940s, Esser-Mittag partnered with another physician named  Dr. Carl Hahn to start a company and market the o.b. Tampon, which stands for one binde or without napkins in German. The company was later sold to American conglomerate Johnson Johnson.   One major selling point the company touts on its website is the fact that a non-applicator tampon can be more environmentally friendly. How so? Johnson Johnson states that 90% of the raw materials that go into o.b. tampons come from renewable resources.
