Strategic Management of Harley-Davidson Research Paper

Strategic Management of Harley-Davidson - Research Paper Example Notably, the company is a US based multinational which specializes on motorcycles. The company was established in the year 1903 and is recognized to possess a strong competitive stance in the current market scenario of the 21st century (Harley-Davidson, â€Å"History†). Based on this thought, the essay shall conclusively intend to identify the major opportunities and threats existing in the US market and the strengths as well as weaknesses possessed by the company. 2.0 The External Environment 2.1 Factors of the Natural Physical Environment Affecting the Corporation and the Industry The components belonging to the natural physical environment of the USA, which affect Harley-Davidson and the motor vehicle industry, can be identified as the energy sources and the trend in its consumption and pricing. The energy sources existing in the US natural physical environment are bioenergy, fossil fuel, coal, hydrogen, hydropower, oil, solar, wind, geothermal and others. It is worth menti oning in this context that the economy maintains a strategic reserve of fuels in order to face the future challenges. This provides the company and the industry with the opportunity of minimized threats in terms of lacuna in energy efficiency of the economy and increasing prices of the fuel which in turn can hamper the future prospects of the company and the industry as a whole. On the contrary, it also raises the future threat of stringent legal barriers and increased tax rates due to the reduction in the level of reserve (U.S. Department of Energy, â€Å"Strategic Petroleum Reserve Annual Report for Calendar Year 2009†). 2.2 General Environmental Forces Affecting the Corporation and the Industry US economy is observed to be at its recovery stage, after being strongly affected by the recent global recession. The GDP rate is growing moderately with an increase in the unemployment rate. This in turn is expected to reduce the consumer purchase rate and thus prove to be a signif icant threat for the company and the industry in the current phenomenon (The Economic Times, â€Å"US Economy Grows 1.8% In Q1, Jobless Claims Rise†). However, political reforms can be recognized to provide with significant opportunities with facilitated investment in the technology sector (U.S. Census Bureau, â€Å"Science and Technology†). With the growing influence of the climate change and other environmental hazards, the US economy has undertaken several strategic measures to reduce greenhouse gas emissions caused by the motor vehicle industry. The measures include strict legal barriers under the regulatory bodies such as, National Emissions Standards for Hazardous Air Pollutants (NESHAP), Clean Air Act (1970) and others (United States Environmental Protection Agency, â€Å"Automotive Repair and Maintenance Sectors (NAICS 8111)†; Natural Resources Defense Council, â€Å"U.S. Environmental Laws†).

Communication and interaction within married couples at church Essay

Communication and interaction within married couples at church - Essay Example This problem depends upon a number of factors, which are both communicational and condemnatory. The principles that underline the seriousness of this problem include blocks like lack of communication, age factor with relevance to immaturity, lack of decision making skills, insensitiveness, early child care situations, and lack of awareness. This prime and most pondered upon issue is being spread like fire all around the researches in contemporary literature, which is why a basis of this issue with reference to its illustration through research will be provided. It is believed that in order for human beings to survive in a society, it is necessary for them to communicate. Is that why man is a social animal? To be accurate, it is true and very much factual. Human beings cannot survive if they are unable to communicate and lack interpersonal skills. Communication skills can be defined as ‘That situation in which a source transmits a message to a receiver with conscious intent to a ffect the latter’s behavior.’ This specifies that the process of expressing thoughts and messages through language or actions is called communication. Hence, it verifies that without the help of communication, human beings cannot continue to exist; especially without speech, because it is thought to be exceedingly imperative as we need to slot in and complete very complex everyday jobs involving collaboration. To validate that proper communication you should be is indispensable; Bach & Grant (2009) said â€Å"There are times, though, when we experience situations where we consider that an interaction did not go smoothly; perhaps we were misunderstood or a friend reacted differently to how we expected.† Explaining the importance of communication between couples, another important term with reference to communication, is ‘nonverbal communication skills’; these skills are meant to make the communicator feel safe, respected, and understood. Petersen (20 07) has verified â€Å"Listening to understand requires a non-judgmental attitude that can go against what most of us were taught, that is, to listen for rights and wrongs.† Therefore, the aspect which has been selected for influencing problems that married couples face is lack of communication. Communication students can directly relate to this topic, as it verifies how lack of communication could reform the society and how these students can elucidate its reach. The fact that problems couples face after marriage has immersed in almost all societies, and what is more essential for elaboration is the fact that it is spontaneously shifting its frame of totality in all societies, which makes it perplexed to be analyzed in a specified precinct. Hence, this problem, its effectiveness and its causes are under assessment with the help of reviewing literature and a qualitative research method. It has been formulated that misunderstandings between couples emerge due to the fact that men and women communicate differently. Instead of communicating with each other, couples tend to talk to others about it and do not gain the idea that this would not solve problems. What needs to be pondered upon is that while staying on this path, couples become hopeless and verify that communication is of no use. Rather than making each other understand the issues they are facing, couples move towards differences which lead to problems like divorces and separations. The specified reason that this topic has been

Summary and Analysis of the Compton Effect

Summary and Analysis of the Compton Effect En = nhf (1) where En is the energy, n is a non-negative integer, h is Plancks constant, and f is the frequency of the photon.2 In 1905, Albert Einstein extended Plancks inference to include not only black body radiation but all electromagnetic waves! Therefore, Einstein hypothesized that light is quantized with energy proportional to its frequency.3 The obvious principle to be deduced from these discoveries is that light possessed attributes of waves and particles! In 1922, Arthur Holly Compton solidified Plancks assumption and therefore firmly established a new era of physics. Compton theorized and then experimentally demonstrated that electromagnetic waves had the properties of particles. Classically, x-rays would shake the electrons of a target material at the same frequency of the x-ray. Hence, the wavelength of radiation from the oscillating electrons would be identical to the wavelength of the incoming xrays. 1 However, it was observed that x-rays were more easily absorbed by materials than waves of longer wavelength. In other words, the scattered  x-rays were of longer wavelength.4 This was contrary to the predictions of classical physics. Compton realized though, that if the interaction was modeled as a collision between two particles (electron and photon), the scattered x-rays would-be of longer wave length (compared to the incident-rays) because the recoiling electron would acquire some of the energy and momentum of the  incoming x-ray.4 Since wavelength is inversely proportional to frequency, the frequency of the scattered x-rays was less. From eq. (1), it is seen  that the energy would also be decreased. When Compton carried out this experiment in 1922 using molybdenum as his target, he verified his theory and provided even more evidence that light also possessed a mass less particle nature Detailed Description of Compton Effect   the elastic scattering of electromagnetic radiation by free electrons, accompanied by an increase in wavelength; it is observed during scattering of radiation of short wavelength-X rays and gamma rays. The corpuscular properties of radiation were fully revealed for the first time in the Compton Effect. The Compton effect was discovered in 1922 by the American physicist A. Compton, who observed that X rays scattered in paraffin have a longer wavelength than the incident rays. Such a shift in wavelength could not be explained by classical theory. In fact, according to classical electrodynamics, under the influence of the periodic electric field of an electromagnetic (light) wave, an electron should oscillate with a frequency equal to that of the wave and consequently should radiate secondary (scattered) waves of the same frequency. Thus, in classical scattering (the theory of which was provided by the British physicist J. J. Thomson and is therefore called Thomson scattering) the wavelength of the light does not change. An elementary theory of the Compton effect based on quantum concepts was given by Compton and independently by P. Debye. According to quantum theory a light wave is a stream of light quanta, or photons. Each photon has a definite energy Ø ¹ =hv=hc/ÃŽÂ »and a definite momentum pÃŽÂ ³= (h/ÃŽÂ »)n, where ÃŽÂ » is the wavelength of the incident light (vis its frequency),cis the speed of light,his Plancks constant, and n is the unit vector in the direction of propagation of the wave (the subscript ÃŽÂ ³ denotes a photon). In quantum theory the Compton Effect appears as an elastic collision between two particles, the incident photon and the stationary electron. In every such collision event the laws of conservation of energy and momentum are obeyed. A photon that has collided with an electron transfers part of its energy and momentum to the electron and changes its direction of motion (it is scattered); the decrease in the photons energy signifies an increase in the wav elength of the scattered light. The electron, which previously had been stationary, receives energy and momentum from the photon and is set in motion (it experiences recoil). The direction of motion of the particles after the collision, as well as their energy, is determined by the laws of conservation of energy and momentum (Figure 1). Elastic collision of a photon and an electron in the Compton effect. Before the collision the electron was stationary:pÃŽÂ ³and pÃŽÂ ³are the momentum of the incident and scattered photons, pe=mvis the momentum of the recoil electron (vis its velocity),(is the photons scattering angle, and à ¸ is the angle of escape of the recoil electron relative to the direction of the incident photon. Simultaneous solution of the equations expressing the equality of the summed energies and momentums of the particles before and after the collision (assuming that the electron is stationary before the collision) gives Comptons formula for the shift in the wavelength of the light: =ÃŽÂ » à ¢Ã‹â€ Ã¢â‚¬â„¢ÃƒÅ½Ã‚ »=ÃŽÂ »0(1 Ë- cos ÃŽÂ ¸) Here ÃŽÂ » is the wavelength of the scattered light, ÃŽÂ ¸ is the photons scattering angle, and ÃŽÂ »0=h/mc= 2.426 ÃÆ'- 10Ë-10cm = 0.024 angstrom (Ã…) is the Compton wavelength of the electron (mis the mass of the electron). It follows from Comptons formula that the shift in the wavelength does not depend on the wavelength ÃŽÂ » of the incident light itself. It is solely determined by the scattering angle ÃŽÂ ¸ of the photon and is maximal when ÃŽÂ ¸ = 180 °, that is, when scattering is straight back: max= 2ÃŽÂ »o. Expressions for the energy Ø ¹eof the recoil, or Compton, electron as a function of the angle à ¸ of its escape may be obtained from the same equations. The dependence of the energy Ø ¹ ÃŽÂ ³ of the scattered photon on the scattering angle ÃŽÂ ¸, as well as the dependence of Ø ¹eon à ¸, which is related to it, is shown in Figure 2. From the figure it is apparent that the recoil electrons always have a velocity component in the direction of motion of the incident photon (that is, à ¸ does not exceed 90 °). Experiment has confirmed all the above theoretical predictions. The correctness of the corpuscular concepts of the mechanism of the Compton effect-and thus the correctness of the basic assumptions of quantum theory-has been experimentally proved. In actual experiments on the scattering of photons by matter, the electrons are not free but are bound to atoms. If the energy of the photons is high in comparison with the binding energy of the electrons in the atom (X-ray and gamma-ray photons), then the electrons experience a recoil strong enough to expel them from the atom. In this case the photon scattering proceeds as if with free electrons. However, if the energy of the photon is not sufficient to tear the electron from the atom, then the photon exchanges energy and momentum with the entire atom. Since the mass of the atom is very great compared to the photons equivalent mass (which, according to the theory of relativity, equals  £y/c2), the recoil is virtually nonexistent; therefore, the photon Dependence of the energyØ ¹ÃƒÅ½Ã‚ »of the scattered photon on the scattering angleÃŽÂ ¸(for convenience, only the upper half of the symmetrical curve is depicted) and the dependence of the energy Ø ¹eof the recoil electron on the angle of escape 0 (lower half of the curve). Quantities related to the same collision event are labeled with identical numbers. The vectors drawn from point 0, at which the collision between the proton with energy Ø ¹ÃƒÅ½Ã‚ ³ and the stationary electron occurred, to corresponding points on the curves depict the state of the particle after scattering: the magnitudes of the vectors give the energy of the particles, and the angles formed by the vectors with the direction of the incident photon define the scattering angle à ¸ and the angle 0 of the recoil electrons path. (The graph was plotted for the case of scattering of hard X rays with wavelengthhc/Ø ¹ÃƒÅ½Ã‚ ³= ÃŽÂ ³o= 0.024 Ã….)  is scattered without a change in its energy (t hat is, without a change in its wavelength, or coherently). In heavy atoms only the peripheral electrons are weakly bound (in contrast to the electrons filling the inner shells of the atom), and therefore the spectrum of the scattered radiation has both a shifted (Compton) line, from scattering by the peripheral electrons, and an un-shifted (coherent) line, from scattering by the entire atom. With increasing atomic number (nuclear charge) the electron binding energy increases, the relative intensity of the Compton line decreases, and that of the coherent line increases. The motion of the electrons in atoms leads to a broadening of the Compton lines in the scattered radiation. This occurs because the wavelength of the incident light appears to be slightly changed for moving electrons; in addition, the amount of change depends on the magnitude and direction of the electrons velocity (the Doppler effect). Careful measurements of the intensity distribution in a Compton line, which reflects the velocity distribution of the electrons in the material, has confirmed the correctness of quantum theory, according to which electrons obey Fermi-Dirac statistics. The simplified theory of the Compton Effect examined here does not permit the calculation of all characteristics of Compton scattering, particularly the intensity of photon scattering at various angles. A complete theory of the Compton Effect is provided by quantum electrodynamics. The intensity of Compton scattering depends on both the scattering angle and the wavelength of the incident radiation. Asymmetry is observed in the angular distribution of the scattered photons: more photons are scattered forward, and the asymmetry increases with increasing energy of the incident photons. The total intensity of Compton scattering decreases with an increase in the energy of the primary photons (Figure 3); this indicates that the probability of the Compton scattering of a photon passing through matter diminishes with decreasing energy. Such a dependence of intensity on  £y determines the place of Compton scattering among the other effects of interaction between matter and radiation that ar e responsible for loss of energy by photons in their passage through matter. For example, in lead the Compton effect makes the main contribution to the energy loss of photons at energies of the order of 1-10 mega electron volts, or MeV (in a lighter element, aluminum, this range is 0.1-30.0 MeV); below this region it is surpassed by the photoelectric effect, and above it by pair production. Compton scattering is used extensively in studying the gamma radiation of nuclei; it is also the basis of the principle of operation of some gamma spectrometers. The Compton effect is possible not only for electrons but also for other charged particles, such as protons; however, because of the protons large mass its recoil is noticeable only during the scattering of photons with very high energy. The double Compton effect consists of the formation of two scattered photons in place of a single incident photon during scattering by a free electron. The existence of this process follows from quantum electrodynamics; it was first observed in 1952. Its probability is approximately a hundred times less than that of the ordinary Compton effect. Graph showing the dependence of the total Compton scattering intensity Inverse Compton effect. If the electrons on which electromagnetic radiation is scattered are relativistic (that is, if they are moving with speeds close to the speed of light), then in an elastic collision the wavelength of the radiation will decrease: the energy and momentum of the photons will increase at the expense of the energy and momentum of the electrons. This phenomenon is called the inverse Compton effect and is often used to explain the radiation mechanism of cosmic X-ray sources, the production of the X-ray component of the background galactic radiation, and the transformation of plasma waves into high-frequency electromagnetic waves. Description of the phenomenon By the early 20th century, research into the interaction ofX-rayswith matter was well underway. It was known that when a beam of X-rays is directed at an atom, an electron is ejected and is scattered through an angleÃŽÂ ¸.Classical electromagnetismpredicts that the wavelength of scattered rays should be equal to the initial wavelength;-9-2[3]however, multiple experiments found that the wavelength of the scattered rays was greater than the initial wavelength. In 1923, Compton published a paper in thePhysical Reviewexplaining the phenomenon. Using the notion ofquantized radiationand the dynamics ofspecial relativity, Compton derived the relationship between the shift in wavelength and the scattering angle: Where ÃŽÂ »is the initial wavelength, ÃŽÂ »Ãƒ ¢Ã¢â€š ¬Ã‚ ²is the wavelength after scattering, his thePlanck constant, meis the mass of the electron, cis thespeed of light, and ÃŽÂ ¸is the scattering angle. The quantityhà ¢Ã‚ Ã¢â‚¬Å¾mecis known as theCompton wavelengthof the electron; it is equal to2.43ÃÆ'-10à ¢Ã‹â€ Ã¢â‚¬â„¢12m. The wavelength shiftÃŽÂ »Ãƒ ¢Ã¢â€š ¬Ã‚ ²Ãƒ ¢Ã‹â€ Ã¢â‚¬â„¢ÃƒÅ½Ã‚ »is at least zero (forÃŽÂ ¸= 0 °) and at most twice the Compton wavelength of the electron (forÃŽÂ ¸= 180 °). Compton found that some X-rays experienced no wavelength shift despite being scattered through large angles; in each of these cases the photon failed to eject an electron.Thus the magnitude of the shift is related not to the Compton wavelength of the electron, but to the Compton wavelength of the entire atom, which can be upwards of 10à ¢Ã¢â€š ¬Ã¢â‚¬ °000 times smaller. Compton Scattering the scattering of3.html#c4x-raysfrom electrons in a carbon target and found scattered x-rays with a longer wavelength than those incident upon the target. The shift of the wavelength increased with scattering angle according to the Compton formula: Compton explained and modeled the data by assuming a particle (photon) nature for light and applying conservation of energy and conservation of momentum to the collision between the photon and the electron. The scattered photon has lower energy and therefore a longer wavelength according to the2.html#c3Planck relationship. At a time (early 1920s) when the particle (photon) nature of light suggested by the1.html#c2photoelectric effectwas still being debated, the Compton experiment gave clear and independent evidence of particle-like behavior. Compton was awarded the Nobel Prize in 1927 for the discovery of the effect named after him. Compton Scattering Data Comptons original experiment made use of molybdenum K-alpha x-rays, which have a wavelength of 0.0709 nm. These were scattered from a block of carbon and observed at different angles with a2Bragg spectrometer. The spectrometer consists of a rotating framework with a calcite crystal to diffract the x-rays and an ionization chamber for detection of the x-rays. Since the spacing of the crystal planes in calcite is known, the angle of diffraction gives an accurate measure of the wavelength. Examination of the Compton scattering formula shows that the scattered wavelength depends upon the angle of scattering and also the mass of the scattered. For scattering from stationary electrons, the formula gives a wavelength of 0.0733 nm for scattering at 90 degrees. That is consistent with the right-hand peak in the illustration above. The peak which is near the original x-ray wavelength is considered to be scattering off inner electrons in the carbon atoms which are more tightly bound to the carbon nucleus. This causes the entire atom to recoil from the x-ray photon, and the larger effective scattering mass proportionally reduces the wavelength shift of the scattered photons. Putting the entire carbon nuclear mass into the scattering equation yields a wavelength shift almost 22,000 times smaller than that for an unbound electron, so those scattered photons are not seen to be shifted. The scattering of photons from charged particles is called Compton scattering after Arthur Compton who was the first to measure photon-electron scattering in 1922. When the incoming photon gives part of its energy to the electron, then the scattered photon has lower energy and according to the2.html#c3Planck relationshiphas lower frequency and longer wavelength. The wavelength change in such scattering depends only upon the angle of scattering for a given target particle. The constant in the Compton formula above can be written and is called the Compton wavelength for the electron. The formula presumes that the scattering occurs in the rest frame of the electron Compton scattering occurs when the incident x-ray photon is deflected from its original path by an interaction with an electron. The electron is ejected from its orbital position and the x-ray photon loses energy because of the interaction but continues to travel through the material along an altered path. Energy and momentum are conserved in this process. The energy shift depends on the angle of scattering and not on the nature of the scattering medium. Since the scattered x-ray photon has less energy, it has a longer wavelength and less penetrating than the incident photon. Compton Effect was first observed by Arthur Compton in 1923 and this discovery led to his award of the 1927 Nobel Prize in Physics. The discovery is important because it demonstrates that light cannot be explained purely as a wave phenomenon. Comptons work convinced the scientific community that light can behave as a stream of particles (photons) whose energy is proportional to the frequency. The change in wavelength of the scattered photon is given by: Where: L = wavelength of incident x-ray photon l = wavelength of scattered x-ray photon H = Plancks Constant: The fundamental constant equal to the ratio of the energy E of a quantum of energy to its frequency v: E=hv. me = the mass of an electron at rest C = the speed of light Q = The scattering angle of the scattered photon The applet below demonstrates Compton scattering as calculated with the Klein-Nishina formula, which provides an accurate prediction of the angular distribution of x-rays and gamma-rays that are incident upon a single electron. Before this formula was derived, the electron cross section had been classically derived by the British physicist and discoverer of the electron, J.J. Thomson. However, scattering experiments showed significant deviations from the results predicted by Thomsons model. The Klein-Nishina formula incorporates the Breit-Dirac recoil factor, R, also known as radiation pressure. The formula also corrects for relativistic quantum mechanics and takes into account the interaction of the spin and magnetic moment of the electron with electromagnetic radiation.Quantum mechanics isa system of mechanics based on quantum theory to provide a consistent explanation of both electromagnetic wave and atomic structure. The applet shows that when a photon of a given energy hits an atom, it is sometimes reflected in a different direction. At the same time, it loses energy to an electron that is ejected from the atom. Theta is the angle between the scattered photon direction and the path of the incident photon. Phi is the angle between the scattered electron direction and the path of the incident photon. Derivation of the scattering formula A photonÃŽÂ ³with wavelengthÃŽÂ »is directed at an electronein an atom, which is at rest. The collision causes the electron to recoil, and a new photonÃŽÂ ³Ãƒ ¢Ã¢â€š ¬Ã‚ ²with wavelengthÃŽÂ »Ãƒ ¢Ã¢â€š ¬Ã‚ ²emerges at angleÃŽÂ ¸. Leteà ¢Ã¢â€š ¬Ã‚ ²denote the electron after the collision. From theconservation of energy, Compton postulated that photons carry momentum;-9-2[3]thus from theconservation of momentum, the momenta of the particles should be related by Assuming the initial momentum of the electron is zero. The photon energies are related to the frequencies by Wherehis thePlanck constant. From therelativistic energy-momentum relation, the electron energies are Along with the conservation of energy, these relations imply that Then From the conservation of momentum, Then by making use of thescalar product, Thus The relation between the frequency and the momentum of a photon ispc=hf, so Now equating 1 and 2, Then dividing both sides by 2hffà ¢Ã¢â€š ¬Ã‚ ²mec, SincefÃŽÂ »=fà ¢Ã¢â€š ¬Ã‚ ²ÃƒÅ½Ã‚ »Ãƒ ¢Ã¢â€š ¬Ã‚ ²=c, Detector characteristics Even large Compton-scatter telescopes have relatively small effective areas. This is because only a small number of the incident gamma-rays actually Compton scatter in the top level. So even if an instrument like COMPTEL has a geometric area of several thousand cm2, the effective area (weighted for the probability of an interaction) is a few tens of cm2. Energy resolution is fairly good for these detectors, typically 5-10% This is limited by uncertainties in the measurements of the energy deposited in each layer. Compton scatter telescopes have wide fields-of-view and can form imageseven though the so-called point spread function (the probability that an event came from a certain area on the sky) is a ring. Applications Compton scattering is of prime importance toradiobiology, as it is the most probable interaction of gamma rays and high energy X rays with atoms in living beings and is applied inradiation therapy.3[4] In material physics, Compton scattering can be used to probe thewave functionof the electrons in matter in the momentum representation. Compton scattering is an important effect ingamma spectroscopywhich gives rise to theCompton edge, as it is possible for the gamma rays to scatter out of the detectors used.Compton suppression is used to detect stray scatter gamma rays to counteract this effect. Inverse Compton scattering Inverse Compton scattering is important inastrophysics. InX-ray astronomy, theaccretion disksurrounding ablack holeis believed to produce a thermal spectrum. The lower energy photons produced from this spectrum are scattered to higher energies by relativistic electrons in the surroundingcorona. This is believed to cause the power law component in the X-ray spectra (0.2-10 keV) of accreting black holes. The effect is also observed when photons from thecosmic microwave backgroundmove through the hot gas surrounding agalaxy cluster. The CMB photons are scattered to higher energies by the electrons in this gas, resulting in theSunyaev-ZelHYPERLINK http://en.wikipedia.org/wiki/Sunyaev-Zeldovich_effectHYPERLINK http://en.wikipedia.org/wiki/Sunyaev-Zeldovich_effectdovich effect. Observations of the Sunyaev-Zeldovich effect provide a nearly redshift-independent means of detecting galaxy clusters. Some synchrotron radiation facilities scatter laser light off the stored electron beam. This Compton backscattering produces high energy photons in the MeV to GeV rangesubsequently used for nuclear physics experiments. Future developments Current research on Compton telescopes is emphasizing ways of tracking the scattered electron. By measuring the direction of the scattered electron in the top level, a complete solution for the incoming trajectory of the cosmic gamma-ray can be found. This would allow Compton telescopes to have more conventional data analysis approaches since the event circle would no longer exist.

The Integration of Cognitive and Behavior Therapy Essay -- Psychology

My personal theoretical orientation to counseling is Cognitive-Behavioral therapy. Cognitive-Behavioral therapy helps the client to uncover and alter distortions of thought or perceptions which may be causing or prolonging psychological distress. The theoretical foundations of CBT are essentially those of the behavioral and cognitive approaches. CBT leads to a clear, persuasive, and evidence-based description of how normal and abnormal behavior develops and changes (Kramer 293). The term â€Å"cognitive-behavioral therapy† or CBT is a term for therapies with many similarities. CBT is not used as a cure and often times used to help with anxiety or depression the most, and may be single or in group settings. There are several approaches to this form of therapy which include, Rational Emotive Behavior Therapy, Rational Behavior Therapy, Rational Living Therapy, Cognitive Therapy, and Dialectic Behavior Therapy. Cognitive-behavioral therapy is based on the idea that our thoughts cause our feelings and behaviors. External things, like people, situations, and events do not. The greatest benefit of this fact is that we can change the way we think, feel, act, and even more so if the situation does not change. In the development of methods of CBT, findings from basic research on the key concepts have been blended with cognitive theories. The most important of these findings are the following: The first is depressive behavior, including low energy, lack of interest, helplessness, and other reductions in psychomotor activity, can be successfully modified with behavioral techniques. The second one is exposure therapy and related methods are particularly effective interventions for many disorders. The last one is that behavioral interventions c... ....

Communication Methods Essay

There are many groups, which the organisation must communicate with such as internal groups and external groups. A type of communication that may take place would be an oral communication. There are many advantages and disadvantages, an advantage would be that oral communication tends to be faster than written forms this allows interpretation and further discussion. A disadvantage would have to be that it lacks the permanent nature of written communication this means it cannot be stored and referred to later. Oral communication includes a face-to-face meeting like interviews. An advantage of this would be that that it’s quick and saves time than writing out forums. A disadvantage would be oral communication depends on the person listening skills. If the listener is not proactive, the communication exercise fails. Oral communication also includes formal meetings; most face-to-face communication is very structured. Most business meetings are often formal and follow a set agenda. Meetings may have a chairman who decides what will be discussed and who will talk. Often a specific person will introduce a point on the agenda. An advantage is that everyone will know what is going to be discussed in advance. A disadvantage is that formal meetings take time to organise. Another oral communication is interviews were there is a formal question and answer session. They can take place in many different situations. They may be used when applying for jobs. Interviews are normally face-to-face communication. Advantage is both sides can ask questions and detailed questions can be asked. A disadvantage is that information given is not always truthful and interviews sometimes do not always show if the applicant can do the job. Another type of communication would have to be a written communication. An advantage of this type of communication would have to be that it would provide ready records and references. Another advantage would be that it is a permanent mean of communicati on. A disadvantage would be there would be too much paper work and e-mails involved and written communication does not save upon the costs. Written communication includes writing letters, and handing out notices, this includes reports. One type of written communication is letters; this is a very formal way of communication. Advantages of this would be that they are confidential, and provide a hard copy. Disadvantages of this would be that it takes time to write letters and takes time for them to arrive and  for replies to be received. Another type would be a memorandum this type of written communication is a simple note from one person to another. In business it is often written in a formalised way. It will be used when someone wishes to send quick messages to one or more people. Advantages would be that they are very quick to write and send and can also be kept as a record. Disadvantage would be people that is not intended for and cannot be useful for long or complicated information could read it. Another type is notice; these are used when a message needs to be sent to a number of people. Notices are formal, most times they are informal. They give information about social events. An advantage is that everyone can see the message, and many people can receive it at the same time. A disadvantage would be it is not confidential and most people may not bother to read it. Records are used to give information about something that has been researched or investigated. They are used in different situations. An advantage would be the formal way of presenting reports means that the reader can easily follow the points being made. Disadvantage would be that they take a long time to research and write. One last type of communication would be electronic communication. This kind of communication could lead to quite a few problems; such as the system could be hacked into therefore important information would be lost this would be a disadvantage. There are advantages of this kind of communication they are simple to use and more and more people are beginning to use the e-mailing system etc. E-mails are the process of using computer networks as a postal system. Data is created on one computer and then is transmitted. An advantage is it can be used to send a wide variety of types of message. A disadvantage is that the sender and receiver must have computers and software that is compatible. Public address is a system that uses microphones and electronically systems to warn about fires. An advantage would be staff could usually hear the message wherever they are in the building. A disadvantage is that if they are used to often staff will stop paying attention. Telephones have been used in business for internal communication. An advantage of this would be that the communication is very quick and telephones allow people to talk to each other. A disadvantage of this would be there is no written record, although telephone conversation  can be record. Another disadvantage would be cost of mobile phones are very high. Fax machine converts pictures and text into electronic pulses which are then transmitted by telephone to another fax machine. Fax machines are less popular because emails can be used instead. An advantage of this would be communication is quick and documents can be sent and received. A disadvantage is it is slower compared to emails. Tele-conferencing is when large business operates on different sites around the country. It’s difficult to get together so they make video calls; this allows them to talk to each other. An advantage would be its much quicker and usually cheaper than bringing people together. An disadvantage wo uld be that these systems are expensive to set up, meeting are more difficult to control because people are in different places.

Best Friend Comparison

Many people have two best friends that are similar and different in many ways. These similarities are usually in age, attitude, and interests; on the other hand, some of the differences between these two friends can include height, beliefs, goals, ethnicities, cultures, and much more. Some people may not find any similarities or differences in their best friends, and others may find many similarities and differences in their friends.However, I find three distinct similarities and three differences within these similarities between my two best friends Daniella and Ashley, which allows me to see that despite these similarities and differences, they are still my best friends. Both Daniella and Ashley have boyfriends, but both boys are treated differently. Daniella and Ashley both live with their mom, but one house is cleaner then the other. Finally, Daniella and Ashley are both very smart, but one applies this smartness more then the other.My two best friends, Daniella and Ashley have b oyfriend. They both have been in their relationships for about 3 years, and they both met their boyfriends in freshman year of high school. Despite the similarity of both having boyfriends for the same amount of time, they treat their boyfriends differently. Daniella treats every moment with her boyfriend as if it were their last moment together. For example, every weekend, she picks her boyfriend up for a date. On the other hand, Ashley takes her boyfriend for granted.For instance, every other weekend, Ashley's boyfriend will pay for dinner and they never go on any dates. Both of my friends have boy friends, but Daniella treats her boyfriend with more respect than Ashley. In addition, Daniella and Ashley live with both their mom in a house. Daniella and Ashley both live in the same neighborhood as me. However, Daniella keeps her house immaculate. Her house is always clean and everything is in order. For example, her carpets always look brand new. Her bathroom is spotless, and her k itchen has everything organized, with the dishes always put away.Ashley's house looks like a tornado ran through it. Ashley's house is always a disaster. For instance, Ashley always has clothes all over the place and shoes everywhere. Her bathroom is completely disgusting. Her kitchen has filthy dishes all over the place and food on the floor. Her place also smells, unlike Daniella's house. Both of my friends live with both their mom in a house, but Daniella clearly knows how to maintain her home, while Ashley either does not care or does not know how to keep a clean home.Finally, both of my best friends, Daniella and Ashley, are extremely smart. Both of them speak very well and read lots of books daily. Daniella and Ashley usually get through the same book in the same amount of time, which is a 200-300 page book every four to five days. Both of my friends know how to discuss the text and analyze it. However, Daniella applies this talent to her schooling and future goal of becoming an Athletic Director, while Ashley does not apply herself at all. Daniella goes to all her classes and passes them with straight A's and B's.On the other hand, Ashley still, after many years, goes to school, but usually has to repeat her courses because she does not go to class regularly, and she is lazy to do the work. If Ashley did apply himself, I believe she would be the same to Daniella and also doing well in school. Either way, both are smart, but one applies herself, while the other does not. In conclusion, my two best friends Daniella and Ashley share many similarities, but within these similarities, they are both different.Both Daniella and Ashley have boyfriends, live with their mom in a house, and they both are very smart. However, Daniella treats her boyfriend with respect and takes him on dates every weekend, while Ashley never checks in with her boyfriend or buys him gifts or go on dates. Daniella's house is very clean and has everything in order. Her dishes are always clean, and her carpets are spotless, while Ashley's house is disgusting. Her bathroom is filthy, and her dishes are always dirty.Ashley also always has clothes all over her floor as well as shoes throwed everywhere. Finally, Daniella and Ashley are very smart and read a lot, but Daniella applies her smartness to school and future, while Ashley fails to discipline herself to move on with school. Either way, my two best friends may have similarities that differ in many and various ways, but one similarity that has no differences is that they are my best friends, and I care about them equally.
