Ethical Issues in Psychology Essay - 1242 Words
We are going to explore the world of ethical issues in psychology. As in any medical or mental health fields there are rules we all must follow as professionals. In this essay today we will be exploring a case study where we have a young lady who has been stricken by a mental disability. We will be looking at the facts in which her disability was handled by a professional in the field of psychology. We also will be discussing the rights and wrongs that are presented in her case study. We will also be discussing the APA ethical codes and gain a clearer understanding of where some things went wrong and why shall we begin. It started on a day in May when a fellow church member had many concerns about a young womanâ⬠¦show more contentâ⬠¦The psychologist did preform an IQ test on Carolyn and came up with a diagnosis of mentally mildly disabled. Letââ¬â¢s stop her what is wrong? This professional has taken a young woman who is mentally disabled and unable to think clearly for her and preformed testing on her. By the contents of this case study there was no consent forms signed for this test. The professional also did not seek out a family member to gain some knowledge of the family history. There was no family background assessed. If this woman is mentally disabled then she is incapable of allowing any kind of testing to be performed because she will not understand the diagnosis nor will she understand what is expected from her. I feel there was misuse of a psychologist assessment. It states in ââ¬Å"1.01 Misuse of Psychologists Work If psychologists learn of misuse or misrepresentation of their work, they take reasonable steps to correct or minimize the misuse or misrepresentationâ⬠in Carolynââ¬â¢s case the psychologist continued on with the assessment without being aware of family background and allowing a mentally disabled woman to make her own decisions even if they did not benefit Carolynââ¬â¢s medical or mental health.

Monsters in Greek Mythology Essay - 1646 Words
One of the most interesting qualities of Greek mythology is probably the depiction of monsters in the myths. However, these monsters are not all unique. In fact, they all fall into very distinct categories, making them almost the same. Most monsters in Greek mythology look and act in the same ways. Several monsters from these myths look the same in that they have very similar qualities such as being large, snake or human like. However, they are also very alike in that they behave in very similar ways, from guarding something or roaming freely and causing chaos. Generally, the monsters in Greek mythology follow this outline and are depicted in a way to show these qualities. Throughout several myths, monsters are described as many diverseâ⬠¦show more contentâ⬠¦It also terrorized the neighboring towns and villages. Medusa also has snake-like characteristics. Her hair is made of snakes and she depicted as evil because she turns people to stone. Overall, there are several monsters that contain snake-like characteristics and it is used to show them as an evil part of society. Probably some of the most fearsome and violent monsters contain characteristics of a lion. A prime example is the Nemean lion. This lion was vicious and could not be hurt by bronze or stone. Since the lion is a very powerful and fierce animal, this monster is especially feared because it is partially lion and invincible to weapons. The Griffin is another ferocious monster that has the body of a lion but the head and wings of an eagle. It is especially known to guard treasure. It is a mix of the lion, the king of beast, and the eagle, king of birds, so it was very powerful. In general, monsters with lion characteristics are very powerful and feared. Several monsters such as the Minotaur, Medusa, and centaurs appear to be partially human. The Minotaur, for example, has the head of a bull but the body of a man. He was born as the offspring of Minosââ¬â¢s wife and a beautiful bull sent by Poseidon. However, Minosââ¬â¢s wife was forced to love the bull by Poseidon. On the other hand, Medusa was born a beautiful woman until she upset Athena who turned her into a terrifying monsterShow MoreRelatedHow Child Abuse Affects a Hero, a God, and a Monster in Greek Mythology811 Words à |à 4 Pagesworld.

Polarizer is cardinal constituent for devices which require a individual polarisation for their operation. We will write a custom essay sample on Design of Single Mode TE Mode Optical Polarizers or any similar topic only for you Order Now Most of the polarizers use metal clad wave guides with proper thickness and refractile index of screen and substrate. Index Termsââ¬â Optical Polarizer, Multi-layered wave guide, TE manner, Silicon oxynitride Introduction Optical wave guide: An optical wave guide is a physical construction that guides electromagnetic moving ridges in the optical spectrum. Common types of optical wave guides include optical fiber and rectangular wave guides. To manufacture a planing machine wave guide ( Fig.1 ) , normally a movie ( refractile indeximg alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/1498805.001.png") , with a screen bed ( refractile indeximg alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/1498805.002.png") , is grown on a substrate ( refractile indeximg alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/1498805.003.png") such thatimg alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/1498805.004.png"Such wave guides are known as asymmetric wave guides. For symmetric wave guide, the screen and substrate are fabricated with same stuff and the refractile indices are equal, i.e.img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/1498805.005.png". If there are more than one bed between Cover and Substrate, so such type of optical wave guides are known as Multilayer Waveguide. In a multi-layered wave guide, we have pick to manufacture as many beds as we required. We can choose the thickness of the beds and the type of the stuff harmonizing to our demand. img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/1498805.006.png"/ Fig. 1 Geometry of 3-layer wave guide construction For a N-layer construction, theDefineframe receives the vacuity wavelength, the refractile index valuesns ( substrate ) , n1, â⬠¦ , nN ( interior beds 1 to N ) , nc ( screen ) , and the thicknessest1, â⬠¦ , tNof the interior beds.

The figure illustrates the relevant geometry: img alt="Planar" geometry="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/1498805.007.png" waveguide=""/ Fig.2 Geometry of multilayer wave guide construction Multilayer wave guides are used in the execution of a assortment of optical devices including semiconducting material optical masers, modulators, wave guide polarisers, Bragg reflectors, and directional couplings. During the last 20 old ages, many efforts have been made to work out the moving ridge equation for the propagating manners in a general, lossless or lossy multilayer wave guide, in such a manner as to ease the design and optimisation of the above optical devices. TE-Pass Polarizer Silicon oxynitride ( SiON ) planar waveguide construction can be fabricated by utilizing plasma enhanced chemical vapor deposition ( PECVD ) . In this technique oxidization reaction is initiated by plasma instead than utilizing external warming beginning. Other techniques are runing technique, vapour stage deposition technique but CVD technique is superior. These wave guides find assorted applications in optical communicating particularly as wavelength filter, microresonator, modulator, polarisation splitter and 2nd harmonic generator. A SiON guided movie is used as multilayered wave guide and utilizing transportation matrix method we propose the application of wave guide as a TE-Pass polarizer and TM-Pass polarizer holding a passband in the 3rd optical communicating window of 1550 nanometer. Polarizer is cardinal constituent for devices which require a individual polarisation for their operation. Most of the polarizer usage metal clad wave guides with proper thickness and refractile index of screen and substrate. Multilayer wave guides are used in the execution of a assortment of optical devices including semiconducting material optical masers, modulators, waveguide polarizer, Bragg reflectors, and directional couplings. We propose a multilayered SiON wave guide fabricated on substrate and has metalimg alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/1498805.008.png"as screen is shown in fig 2. The pick of SiON is made for its extremely desirable characteristics such as low interpolation loss, broad scope of refractile index tailoring and realisation of compact devices because of its low bending loss. The present constellation of optical polarizer will happen applications in incorporate optical circuits, signal processing from fiber ocular detectors and fiber gyroscopes. For the analysis of the wave guide we have used the transportation matrix preparation. img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/1498805.009.png" img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/1498805.010.png" Fig.3 Geometry of multilayer wave guide construction img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/1498805.011.png"= refractile index of the screen img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/1498805.012.png"= refractile index of the movie i=1, 2â⬠¦Ã¢â¬ ¦Ã¢â¬ ¦r img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/1498805.013.png"= refractile index of the substrate img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/1498805.014.png"= thickness of the movie bed in micrometer img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/1498805.015.png"= thickness of the movie bed in micrometer Figure 1:Formulation For the computation of extension invariable and ensuing extension manner profile of multi-layered wave guide, there are following methods: ââ¬â 1. Disturbance Method ( 4-layer ) 2. Newtonââ¬â¢s Method 3. Mode-matching method ( 5-layer construction ) 4. Transfer Matrix Formulation 5. Argument Principle Method The disturbance method for a lossless 5-layer construction, for a lossy 4-layer construction, and for a metal-clad wave guide was used to find the extension invariables and the ensuing propagating manner profiles. Newtonââ¬â¢s method was used for metal-clad wave guides where the derived function of the scattering equation can be obtained analytically. A graphical method, every bit good as formal electromagnetic analysis methods such as the mode-matching method, was besides used. The disturbance method every bit good as Newtonââ¬â¢s method can non easy be extended to multilayer constructions, since their attack is analytic and the expression involved become cumbersome. None of the above methods can easy foretell the figure of propagating manners supported by the multilayer construction. This is a serious job since there is no manner of cognizing when to halt seeking for new propagating manners or even if the wave guide really can back up any manner at all. In fact, an extra analysis must be used to find the figure of guided manners before using the zero-searching techniques. Even if the figure of bing propagating guided manners is given, there is no verification that all the manners will be found. All the above mentioned methods have serious jobs in turn uping closely spaced roots. Furthermore, all of them need an initial estimate near to the existent nothing. This initial estimation may be hard to happen, particularly for high-loss propagating manners where the popular disturbance method does non use. The method which we are utilizing, is based on complex figure theory. It is capable of happening the nothing or poles of any analytic map in the com plex plane. The scattering equation of a general multilayer wave guide is formed via the construct of thin-film transfer-matrix theory. After its uniqueness points are observed, the complex plane is divided into parts where the scattering equation is analytic, and all the zeros inside each part are found. In add-on, the method provides the figure of nothing or poles in each part. The transfer-matrix analysis provides an easy preparation of the multilayer construction job. The method will be presented for TE manners but the extension to TM manners is straightforward. img alt="" src="https://s3-eu-west-1.amazonaws.com/aaimagestore/essays/1498805.016.png"/ Fig.4 TE-Pass Polarizer A multilayer nonmagnetic slab wave guide construction( à µ=à µO) ,is shown in Fig. 2.

The value of stage changeless and fading invariable for 6-layer Lossy Dielectric Waveguide are available. The available informations were calculated by the method of Argument Principle ( APM ) . Transportation Matrix method has been used to analyze a four superimposed waveguide dwelling of SiON as guiding movie. On this footing, we have designed TE base on balls polarizer. The scope of SiON movie thickness was estimated so that merely the cardinal pervert TE0is supported. The computations showed that in the thickness scope of 0.7à µm -2.2 à µm of SiON, the wave guide supports merely TE0manner. In TE manner base on balls polarizer, the loss of TE manner is in the scope of 0.2 ââ¬â 2.5 dB/cm and for TM mode its scope is 40 ââ¬â 45 dB/cm, which rather higher in comparing to TE manner. So in this type of constellation of four bed wave guide, merely TE manner will go through.
