Communications Essay 1. What is an implication, in general, and what are specific implications of the presence of the U.S. flag, Constitution, and Bill Of Rights in all the classrooms at the University of Arizona? a. A general definition of an implication is an assumption that can be inferred from a given scenario that is not obviously specified. The US flag, Constitution, and Bill of Rights are all important symbols of freedom in the United States. The Bill of Rights contains the first ten amendments to the Constitution that preserve the liberties and freedoms prevalent in the United States. The Constitution sets forth the structure of the government we created after rebelling against the British monarchy. The US flag contains a representation of the original 13 colonies that rebelled against the British monarchy as the stripes and the current 50 states as the stars, this representation holds a strong symbol of Americanism. A specific implication of having the U.S. flag, Constitution and Bill of Rights in all University of Arizona classrooms is to help remind students of the freedoms that are available to them in the United States. These symbols of personal freedom promote one’s ability to be an outspoken individual, go against the grain in everything they do, and maintain an individual spirit. 2. Problems in business, government, and relationships are frequently blamed on a lack of communication or a failure to communicate properly. Use the Tubbs communication model on page 9 of your Human Communication textbook to diagnose a communication problem and suggest a recommendation for fixing the problem. a. Tubbs’ communication model involves two communicators and contains three main components of communication: the messages, interference, and the channel. Communication problems can exist across all three components of Tubbs’ communication model. Messages can be intentional and unintentional, when we send an unintentional message we give a message that we didn’t intend to and will usually not find out about the error until we receive feedback from the receiver. Communication problems in channels can occur when sending a message through the wrong channel, each channel serves a primary purpose and sending the wrong message through a channel can lead to a breakdown in communication. Interference is what causes a sent message to become misunderstood or missed completely, usually due to a distortion in the message or the receiver becoming distracted. A fairly common problem that has become more prominent in communication since the rise in popularity of electronic messaging is the inability to relate sarcasm, irony, or other emotions effectively. Usually when someone says something sarcastic it can be taken as a serious statement and the receiver can view the sender as ignorant or senseless. To fix this the person either has to relate the message through a more emotionally efficient channel, such as a telephone call, or include a signifier that allows the person to realize the text should be taken as sarcasm, such as including the tag /sarcasm afterwards. 3. What subject matter is at the heart of the field of communication? To answer this question, imagine that a friend or family member asked you what ‘communication’ as an academic subject was about. How would you respond to that person so that they had a clear understanding? a. Communication has changed a great deal over the last 2400 years but has always maintained a primary center to its study while adding more and more elements. In ancient Greece, Socrates and Plato used communication (then called Rhetoric) as a means to discover the truth and draw it out of their students. Aristotle took Plato’s view and expanded onto it that truth is not always absolute and humans must therefore ascertain the â€Å"probable† truth. These early understandings still hold relevant today and create a framework for the contemporary study of human communication. At the heart of communication is the need for understanding, the need for people to be able to help others understand what they’re saying and understand what others are saying. With this need for understanding Plato stated that rhetoric would be used to promote falsehood over truth while Aristotle saw that either falsehood or truth could be promoted and it is the duty of the citizen to use rhetoric to defend the truth. Communication covers the central topic of providing information to other people through multiple channels in an efficient and effective manner. As communication progresses it will continue to hold its central subject matter while adding more and more relevant areas of interpretation. 4. How was the ancient Greek city-state of Athens involved in the history of communication? What connections exist between communication in ancient Athens and communication in the world today? a. Athens was home to the three scholars who created the two primary views to what we currently know as communication. Socrates, Aristotle and Plato provided a strong foundation for the study of communication while coming from two different views of rhetoric. Socrates and Plato were credited to creating the view of â€Å"Divine Truth† which sought to use reasoning and dialogue to â€Å"draw out† knowledge and understanding. Where as, Aristotle viewed that truth is all around in the environment and must be taken in through the senses. Much of what Socrates, Aristotle and Plato put into communication (rhetoric) is still valid today; Aristotle stated communication is â€Å"purposive† and can be evaluated on whether they accomplish their purpose. Socrates demonstrated a strong relationship between communication that would result in the discovery and appreciation of truth and beauty; this gave a precedent to the value of ethics in communication. Each view puts value into a different way of viewing the truth that surrounds us every day; one sees that there is truth in everything and it’s up to the individual to find that truth while the other views that truth is dependent on the person and can change depending on a persons view. These two views from ancient Athens will continue to lead the study of communication and help shape the continued understanding of the field.

Market Research in Housewares :: Marketing, business, products,

It’s certainly been one of the most eventful years on record for the housewares industry, with the economy in freefall and the decline of some of the industry’s most respected household names– there really was very little to cheer about. There are still many â€Å"what ifs† out there. It’s impossible to predict the outcome, but on one- side there is the issue of rising inflation, unemployment and a general election which will keep consumers holding tightly on to their purse strings and demanding more from the industry. By this I mean, demanding products that are well designed, ethically sourced and competitively priced. This is going to provide suppliers with a range of major challenges over the coming year. New Priorities One of the outcomes of a recession is that people often re-evaluate the way they live their lives and whereas before purchase decisions probably didn’t require a great deal of thought, this is no longer the case and every single pound spent will need to count. On the more positive side, 2010 will see new suppliers and retailers enter the market, companies who have taken advantage of vacant space available on the high street and also gaps in the supply chain. One of the areas that I believe will continue to grow is high-end contemporary established brands as well as smaller altruistic retailers. These newcomers focus specifically on quality, service, design and lifestyle. Many established names like Emma Bridgewater and Cath Kidston have grown their businesses during 2009 and have a strong foot hold in the market. They continue to provide their customers with fantastic â€Å"lifestyle stories† and fresh contemporary designs as well as playing on their â€Å"Made in Britain† traits or feeding the â€Å"homespun† lifestyle concept, a trend which will be with us for quite some time and which consumers still wish to emulate. Opportunities Whilst supermarkets and discount stores strive to increase their market share at the expense of domestic producers and specialist retailers, I still believe that there are opportunities out there for the smaller retailer. You only have to look at Lakeland - the mail order company - who continues to thrive in difficult market conditions due to a fantastic mix of great product offers and outstanding customer care. Whilst companies strive to compete in difficult economic times, I do believe that those who really understand their market and customer needs will continue to grow.

Explanation of Modern Physics

Explanation of Modern Physics While the term â€Å"modern physics† often suggests that all that came before it was incorrect, 20th and 21st century additions to physics simply modified and expanded the phenomena which Newton and his fellow scientists had already contrived. From the mid-1800’s onward, new advances were made in the way of physics, specifically the revolutions of Einstein’s relativity, removing mankind further from the absolute, and quantum mechanics, which replaced certainty with probability. All of this led to an advance in nuclear weaponry, the advancement of laser technology, and the information age of computers.Although it directly contradicted the classical equipartition theorem of energy, black body radiation was one of the first discoveries in modern quantum mechanics. This theorem states that within thermal equilibrium, where each part of the system is the same temperature, each degree of freedom has 12kBT, kB representing the Boltzmann con stant, of thermal energy associated with it, meaning that the average kinetic energy in the translational movement of an object should be equal to the kinetic energy of its rotational motion.By this point, it was known how heat caused the atoms in solids to vibrate and that atoms were patterns of electrical charges, but it was unknown how these solids radiated the energy that they in turn created. Hertz and other scientists experimented with electromagnetic waves, and found that Maxwell’s previous conjectures that electromagnetic disturbances should propagate through space at the speed of light had been correct. This led to the explanation of light itself as an electromagnetic wave.From this observation, it was assumed that as a body was heated, the atoms would vibrate and create charge oscillations, which would then radiate the light and the additional heat that could be observed. From this, the idea of a â€Å"black body† formed, an object that would absorb all radia tion that came in contact with it, but which also was the perfect emitter. The ideal black body was a heated oven with a small hole, which would release the radiation from inside.Based on the equipartition theorem, such an oven at thermal equilibrium would have an infinite amount of energy, and the radiation through the hole would show that of all frequencies at once. However, when the experiment was actually performed, this is not the result that occurred. As the oven heated, different frequencies of radiation were detected from the hole, one at a time, starting with infrared radiation, followed by red, then yellow light, and so on.This proved that high oscillators are not excited at low temperatures, and that equipartition was not accurate. This discovery led to Stefan’s Law, which said that the total energy per square unit of black body per unit time, the power, is proportional to the absolute temperature to the fourth power. It also led to Wien’s Displacement Law, stating that the wavelength distributions of thermal radiation of a black body at all temperatures have essentially the same shape, except that the graphs are displaced from each other.Later on, Planck characterized the light coming from a black body and derived an equation to predict the radiation at certain temperatures, as shown by the diagram below. For each given temperature, the peaks changed position, solidifying the idea that different temperatures excite different levels of the light spectrum. This was all under the assumption that radiation was released in quanta, now known as photons. All of these laws help modern physicists interpret radiation and make accurate estimations at the temperature of planets based on the radiation that comes from them.Einstein used the same quantization of electromagnetic radiation to show the photoelectric effect, which disproved the idea that more intense light would increase the kinetic energy of the electrons radiated from an object. Photo electric effect was originally the work of Heinrich Hertz, but was later taken on by Albert Einstein. Einstein determined that light was made up of packets of energy known as photons, which have no mass, but have momentum and energy given by the equation E=hf, h representing Planck’s constant and f representing the frequency of the light used.Photoelectric effect explains that if light is shone on a metal with high enough energy, electrons will be released from the metal. Due to the energy equation, light of certain low frequencies will not cause the emission of electrons, not matter how intense, while light of certain high frequencies will always emit electrons, even at a very low intensity. The amount of energy needed to release electrons from a metal plate is dependent upon the type of metal it is, and changes from case to case, as every type of metal has a certain work function, or an amount of energy needed to remove an electron from its surface.If the photons that hit t he metal plate have enough energy as the work function of the metal, the energy from the photon can transfer to an electron, which allows it to escape from the surface of the metal. Of course, the energy of the photon is dependent upon the frequency of the light. Einstein postulated that the kinetic energy of the electron once it has been freed from the surface can be written as E=hf-W, W being the work function of the material. Prior to Einstein’s work in photoelectric effect, Hertz discovered, mostly by accident, that ultraviolet light would knock electrons off of metal surfaces.However, according to the classical wave theory of light, intensity of light changed the amplitude, thus more intense light would make the kinetic energy of the electrons higher as they were emitted from the surface. His experiment showed that this was not the case, and that frequency affected the kinetic energy, while intensity determined the number of electrons that were released. By explaining th e photoelectric effect, scientists find that light is a particle, but it also acts as a wave. This help support particle-wave duality.In order to explain the behavior of light, you must consider its particle like qualities as well as its wave like qualities. This means that light exhibits particle-wave duality, as it can act as a wave and a particle. In fact, everything exhibits this kind of behavior, but it is most prominent in very small objects, such as electrons. Particle-wave duality is attributed to Louis de Broglie in about 1923. He argued that since light could display wave and particle like properties, matter could as well.After centuries of thinking that electrons were solid things with definite positions, de Broglie proved that they had wave like properties by running experiments much like Young’s double slit experiments, and showing the interference patterns that arose. This idea helped scientists realize that the wavelength of an object diminishes proportionally to the momentum of the object. Around the same time that de Broglie was explaining particle-wave duality, Arthur Compton described the Compton effect, or Compton scattering.This was another discovery which showed how light could not solely be looked at as a wave, further supporting de Broglie’s particle-wave duality. Compton scattering is a phenomenon that takes place when a high-energy photon collides with an electron, causing a reduced frequency in the photon, leading to a reduced energy. Compton derived the formula to describe this occurrence to be ? ‘-? =hCme1-cos? = ? c(1-cos? ), where ? ‘ is the resulting wavelength of the photon, ? is the initial wavelength of the photon, ? is the scattering angle between the photon and the electron, and ? c is the wavelength of a resting electron, which is 2. 26 ? 10-12 meters. Compton came about this by considering the conservation of momentum and energy. Although they have no mass, photons have momentum, which is defined by ? =Ec=hfc=h?. In order to conserve momentum, or to collide at all, light must be thought of as a particle in this case, instead of a wave. Quantum mechanics is not the only facet of modern physics, and it shares equal importance with relativity. Relativity is defined as the dependence of various physical phenomena on relative motion of the observer and the observed objects, especially in relation to light, space, time, and gravity.Relativity in modern physics is hugely attributed to the work of Albert Einstein, while classical relativity can be mainly attributed to Galileo Galilei. The quintessential example of Galilean relativity is that of the person on a ship. Once the ship has reached a constant velocity, and continues in a constant direction, if the person is in the hull of the ship and is not looking outside to see any motion, the person cannot feel the ship moving. Galileo’s relativity hypothesis states that any two observers moving at constant speed and direction with respect to one another will obtain the same results for all mechanical experiments.This idea led to the realization that velocity does not exist without a reference point. This idea of a frame of reference became very important to Einstein’s own theories of relativity. Einstein had two theories of relativity, special and general. He published special relativity in 1905, and general relativity in 1916. His Theory of Special Relativity was deceptively simple, as it mostly took Galilean relativity and reapplied it to include Maxwell’s magnetic and electric fields. Special relativity states that the Laws of Physics are the same in all inertial frames.An inertial frame is a frame in which Newton’s law of inertia applies and holds true, so that objects at rest stay at rest unless an outside force is applied, and that objects in motion stay in motion unless acted upon by an outside force. The theory of relativity deals with objects that are approaching the speed o f light, as it turns out that Newton’s laws begin to falter when the velocity gets too high. Special relativity only deals with the motion of objects within inertial frames, and is quite comparable to Galilean relativity, with the addition of a few new discoveries, such as magnetic and electric fields and the speed of light.The theory of general relativity is much more difficult to understand than special relativity due to the fact that it involves objects traveling close to the speed of light within non-inertial frames, or frames that do not meet the requirements given by Newton’s law of inertia. General relativity coincides with special relativity when gravity can be neglected. This involves the curvature of space and time, and the idea that time is not the definite that we have always assumed that it was. General relativity is a theory that describes the behavior of space and time, as well as gravity.In general relativity, space-time becomes curved at the presence o f matter, which means that particles moving with not external forces acting upon them can spiral and travel in a curve, which becomes conflicting with Newton’s laws. In classical physics, gravity is described as a force, and as an apple falls from a tree, gravity attracts it to the center of the Earth. This also explains the orbit of planets. However, in general relativity, a massive object, such as the sun, curves space-time and forces planets to revolve around it in the same way a bead would spiral down a funnel.This idea of general relativity and the curvature of space-time led scientists to realize what black holes were and how they can be possible. This also explains the bending of light around objects. Black holes have massive centers and are hugely dense. Each particle that it includes is also living in space-time however, and so the center must continue to move and become more and more dense from the motion of these particles. Black holes are so dense that they bend s pace-time to an enormous degree, so that there is no escapable route from them.General relativity also explains that the universe must be either contracting or expanding. If all the stars in the universe were at rest compared to one another, gravity would begin to pull them together. General relativity would show that the space as a whole would begin to shrink and the distances between the stars would do the same. The universe could also technically be expanding, however it could never be static. In 1929, Hubble discovered that all of the distant galaxies seemed to be moving away from us, which would support the explanation that our galaxy is expanding.The basis of general relativity is the dynamic movement of space and time, and the fact that these are not static measurements that they have always been assumed to be. However, a key issue is that there has been little success in combining quantum mechanics and Einsteinian relativity, other than in quantum electrodynamics. Quantum el ectrodynamics, QED, is a quantum theory that involves the interaction of charged particles and the electromagnetic field. The scientific community hugely agrees upon QED, and it successfully unites quantum mechanics with relativity.QED mathematically explains the relationships between light and matter, as well as charged particles with one another. In the 1920’s, Paul Dirac laid the foundations of QED by discovering the equation for the spin of electrons, incorporating both quantum mechanics and the theory of special relativity. QED was further developed into the state that it is today in the 1940’s by Richard Feynman. QED rests on the assumption that charged particles interact by absorbing and emitting photons, which transmit electromagnetic forces. Photons cannot be seen or detected in anyway because their existence violates the conservation of energy and momentum.QED relies heavily on the Hamiltonian vector field and the use of differential equations and matrices. F eynman created the Feynman diagram used to depict QED, using a wavy line for photons, a straight line for the electron, and a junction of two straight lines and one wavy line to represent the absorption or emission of a photon, show below. QED helps define the probability of finding an electron at a certain position at a certain time, given its whereabouts at other positions and times. Since the possibilities of where and when the electron can emit or absorb a photon are infinite, this makes this a very difficult procedure.Compton scattering is very prevalent to QED due to its involvement in the scattering of electrons. Modern physics is a simple term used to cover a huge array of different discoveries made over the past two hundred years. While the two main facets of modern physics are quantum mechanics and relativity, there are an amazing number of subtopics and experiments that have brought about rapid change, giving the world new technologies and new capabilities. Thanks to scie ntists like Einstein, Hawking, Feynman, and many others, we have found, and will continue to find, amazing discoveries about our universe.Sources Anderson, Lauren. â€Å"Compton Scattering. †Ã‚  University of Washington Astronomy Department. 12 Nov. 2007.

Review On Thomas More Utopia - Free Essay Example

Sample details Pages: 2 Words: 660 Downloads: 10 Date added: 2019/08/02 Category Society Essay Level High school Topics: Utopia Essay Did you like this example? Thomas More published Utopia in the year of 1516 which was around the time of the Reformation When writing Utopia, More intended his title to mean No Place. Pretty much every detail about Utopia that Hythloday gives is indirectly critiquing parts of Europes fundamental identity. The ending of this book leaves many questions, thus has the reader wondering if this place was simply made up, a perfect society seems impossible, and it is impossible. There are too many aspects of Utopia that completely contradict themselves. Hythloday is clearly unhappy with the state affairs in Europe as he continuously critiques it. As the book goes on it becomes more and more apparent that he is dissatisfied with the way things are going in Europe from corruption, poverty, inequality, and violence. As he describes this differing society on a mysterious island called Utopia he begins to find relief, but even that does not last. Upon his return to Europe, he begins to come to the realization that not a lot of people are open to the idea of the social systems that Utopia uses, and from here things only get more difficult for Hythloday. It becomes clear that even if Hythloday ended up staying in Utopia, he would being to notice flaws with differing aspects of that society as well. To have a true Utopia means that everyone must be satisfied at all times, which is not possible. This even further solidifies Mores meaning of the title meaning No Place, as it is contradictory. Don’t waste time! Our writers will create an original "Review On Thomas More Utopia" essay for you Create order Pride is definitely an issue in the eyes of Hythloday, and he sees it as the main issue for everything from poverty, to bad kings, and any other social, economic, and political issue. He believes pride is the core of all other sins and issues. He explains that in Utopia, pride is never reinforced and therefore it is not an aspect of the society of Utopia. However, not all pride is bad, there are times when pride is even a positive thing and can be essential to accomplishing great things. In retrospect, Hythloday has an issue with pride himself, maybe even more than the rest of Europe as he believes he is correct about everything it takes to create a perfect society. This is another instance of contradictions. It is apparent that Utopia is not a regular, normal island for a multitude of reasons. However, Utopias social organizations are likely the most blatant difference between Utopia and all other societies. In almost a proto-Communist way, Utopia is expressed as a society that lacks a class-system, hierarchies, and yes has very rigid family structures. This is such a radically different manner in which people live together, that More is going back and forth as to whether or not everyone should have equal social status, or if it is better to have some degree of social hierarchy, as it may be valuable. This lack of concrete consistency, again leads to the idea of No Place. Utopia has tons of social commentary, and when Hythloday arrives at Utopia, he is rather bewildered by their unconventional way of eliminating wealth, they have no private property. With the lack of private ownership there is no status of wealth or even status of poverty. Therefore, people are uninterested in being rich. Hythloday likes this because he states there is no greed and therefore everyone is satisfied (except for him, because it makes him think of how greedy and money driven the society of Europe is). Again, this emphasizes that this place could not possibly be perfect. Additionally, owning things brings people joy and can make them happy, it gives them a feeling of personal independence, so it is not realistic that in a society where there is no private property, that everyone is happy. Furthermore, Hythloday claims to despise wealth, but yet he enjoys spending time with his wealthy friends and what their wealth has to offer, which is another instance of him contradicting himself.
