Single Soldiers Essay Example | Topics and Well Written Essays - 750 words

Single Soldiers - Essay Example The truth is that single soldiers make up more than a third of the United States’ army (BOSS site). These soldiers are fighting machines, dedicated to god and country. Nevertheless it helps them to have support at home and not to be all alone. The Army has recognized this, creating Better Opportunities for Single Soldiers (BOSS). According to its website: BOSS provides an avenue for single Soldiers to surface issues and to take part in activities but does not set policy and other guidance on issues. BOSS is intended to enhance command authority, prerogative, and responsibility in maintaining standards of conduct, good order, and discipline, not to dilute. This is an excellent first step in recognizing the problems faced by single soldiers. Drawing such people together into a cohesive unit in order to address their quality of life issues and their morale is a key development in the history of the evolution of the army. These individuals, often young, need sustenance. The Army can provide this too. There are other unique challenges faced by the single soldiers. The benefit structure the army provides is geared towards soldiers with families. This is true of other armies around the world. An excellent example was recently reported in Canada. Canada may have a much smaller standing army than the United States, but there too the problem of single soldiers has surfaced in a public and contentious manner. The families of four unmarried soldiers that were killed in Afghanistan stepped forward recently to file human-rights complaints in that country. They say that the government discriminated in favour of married troops by paying a $250,000 death benefit. According to the Canadian Press: A federal human-rights tribunal rejected the complaint of Lincoln and Laurie Dinning because Veterans Affairs abruptly decided to recognize their sons girlfriend as his common-law spouse,

Study question the Victorians poetry & prose Essay Example for Free

Study question the Victorians poetry prose Essay 1. What is the function of poetry for Mill? Of poets? What differences do you see between his ideal of poetry and the Romantic ideal? The function of poetry, according to Mill, is to act upon the emotions. It differs from prose or science in a sense that while these address beliefs, poetry is to feelings; that while the other two works by â€Å"convincing or persuading†, poetry works by â€Å"moving† emotions; and while the other two presents a â€Å"proposition to the understanding†, poetry â€Å"offers interesting objects of contemplation to the sensibilities. † Poetry should â€Å"paint the human soul truly. † There is not much difference in Mills function of poetry to Romantic ideals in the sense that both appeal to the emotion of the readers. 2. In the passage from his Autobiography, what does Mill become depressed/love his faith? What â€Å"saves† him? What is Mill’s critique of Utilitarian philosophy? Although Mill is a famous exponent of Utilitarianism, he has some objections or criticisms about it. His father was also an exponent of Utilitarianism and here lies his delemma. He took the oppurtunity to publish his criticisms, alongside with his defense, when an earlier work by Professor Sedgwick was published that assaulted utilitarian ethics, and which had given his father and other utilitarians much indignation. 3. What choice is the Lady of Shalott making when she leaves her tower? The Lady of Shalott decides to leave her isolation when she decided to leave her tower. All her life she lived in isolation, that although reapers hears her song, none had seen her and she couldnt look down fro her tower because of the curse if she did so. One time she exclaimed: â€Å"I am half-sick of the shadows. † Even though she resists looking down from her tower, she finally did when she heard Sir Lancelot sing and the curse is starting to manifest on her. Perhaps, at least at the time of death the Lady of Shalott does not wish to be alone but wish herself to be known to others, that she left the tower, labeled the boat she found â€Å"The Lady of Shalott,† and died crossing the river going to Camelot. 4. Is Ulysses’ decision to leave his home again (a) heroic or (b) escapist? Defend your answer. Ulysses decision to leave his home again is an escape to the life in his kingdom. There is nothing heroic in his new conquest, other than to â€Å"seek a newer world† or to â€Å"touch the Happy Isles. † In the beginning of the poem, Ulysses already suggest that there is little point in staying home and states that he â€Å"cannot rest from travel. † He believes that going back to sea again would yeild â€Å"some work of noble note† suggesting that travelling the seas offers a much simpler and fruitful life than staying home. 5. Explain how the setting and circumstances affect our reading of â€Å"My Last Duchess†? Is the narrator reliable? How do we know? The setting and circumstances in My Last Duchess leads the readers to speculate on the mysteries that encompasses the poem, speculatively from actual historical events. The tilte itself reveals that the speaker in the poem is a Duke whose last wife had died. The mention of â€Å"nine-hundred-years-old name† suggest that the Duke came from a long line of prominent and powerful family, and through the speaker we know that he is presenting to his audience his art collections suggesting that he is a lover of the arts. There is little error from the information if we take the popular belief that the speaker was Duke Alfonso II, who lived in the 16th century, to be true. Alfonso II came from the house of Este, whose earliest known member lived in the 10th century, which makes his name â€Å"six-hundred-years-old† at the time the duke lived, in contrast with the â€Å"nine-hundred-years-old name. † 6. According to Arnold what is the value of education in the humanities as opposed to just being educated in science or â€Å"practical† issues? Just being educated in science or practical issues, according to Arnold, has put the world in a state where nothing is certain. It has brought the â€Å"Sea of Faith† in melancholy as scince has challenged the precepts of religion. He hopes that with the confusion brought about by science, education in the humanities would cure the world of its lack of faith. Education in the humanities would, at least, keep the world its moral standards. 7. What does Arnold’s poem, â€Å"Dover Beach† suggest as an antidote to the loss of faith? Do you think the poem ends pessimistically or optimistically? In Dover Beach, Arnold suggest that faithfulness in love is the antidote to the loss of faith. His appeal: â€Å"Ah, love let us be true† suggests that his only hope on this uncertain world rests on the faithfulness of his love interest, probably his wife, to him. The poem still ends pessimistically since Arnold emphasizes on the confusion the world is currently at the time the poem was written.

Earthquake Simulation for Buildings

Earthquake Simulation for Buildings Abstract Earthquake is an independent natural phenomenon of vibration of the ground which can become dangerous mainly when it is considered in relation with structures. Earthquakes can be very weak, without even realizing them but (they) can also be strong enough to result serious damages to buildings which can lead to injures or even loss of human lives. In order to avoid any structural damage the legislation sets conditions on the building design. For that purpose, Eurocode 8 is established in European countries and sets up all the appropriate criteria and measures for the design of buildings for earthquake resistance (Eurocode 8 is established in Europe and suggests 4 different methods of analysis.) In this project the response of eight buildings is examined (investigated) under seismic excitation. Firstly, is examined the case of four buildings (1 storey, 2 storey, 3 storey and 4 storey) where all the storeys are facsimile (replica). Afterwards, is examined the case of four buildings (aga in 1-4 storeys) where while the storeys of each building are increased, the mass, the stiffness and the height of each floor are decreased. Both the lateral method of analysis and the modal response spectrum analysis are used as recommended by EC8 to calculate the inter-storey drifts, the total shear forces and the overturning moments at the base of each building. The results are plotted and compared so that useful outcomes can be obtained. 1. Introduction One of the most frightening and destructive phenomena of nature is a severe earthquake and its terrible aftereffects especially when they are associated with structures. An earthquake is a sudden movement of the Earth, caused by the abrupt release of strain that has accumulated over a long time. Earthquake intensity and magnitude are the most common used parameters in order to understand and compare different earthquake events.( Ά° are the most common parameters used to appreciate and compare.) In recent years have been giving increasing attention to the design of buildings for earthquake resistance. Specific (particular) legislation is (have been) established to make structures able to resist at any seismic excitation. In Europe, Eurocode 8 explains how to make buildings able to resist to earthquakes, and recommends the use of linear and non-linear methods for the seismic design of the buildings Simple structures can be modelled either as equivalent single degree of freedom systems (SDOF) or as a combination of SDOF systems. In this project 8 different buildings with a variation either on the number of storeys or on their characteristics are simulated as a combination of SDOF systems for which the mode shapes and their corresponding eigenfrequencies and periods are calculated. Afterwards the fundamental frequency is obtained for each case and the elastic design is used in order to obtain the base shear forces and the overturning moments. (INELASTIC DESIGN AND LATERAL FORCE METHOD) 2. Literature review 2.1 Introduction to earthquake engineering Definition and earthquake derivation or generation or creation or production or formation or genesis The lithosphere is the solid part of Earth which includes or consists of the crust and the uppermost mantle. The sudden movement of the earths lithosphere is called earthquake (technical name seism). Fractures in Earths crust where sections of rock have slipped past each other are called Faults. Most earthquakes occur along Faults. Generally, earthquakes are caused by the sudden release of built-up stress within rocks along geologic faults or by the movement of magma in volcanic areas. The theory of plate tectonics provides geology with a comprehensive theory that explains how the Earth works. The theory states that Earths outermost layer, the lithosphere, is broken into 7 large, rigid pieces called plates: the African, North American, South American, Australian- Indian, Eurasian, Antarctic, and Pacific plates. Several subcontinental plates also exist, including the Caribbean, Arabian, Nazca, Philippines and Cocos plates. Boundaries of tectonic plates are found at the edge of the lithospheric plates and can be of various forms, depending on the nature of relative movements. By their distinct motions, three main types can be characterized. The three types are: subduction zones (or trenches), spreading ridges (or spreading rifts) and transform faults.. convergent, divergent and conservative. At subduction zone boundaries, plates move towards each other and the one plate subducts underneath the other (ÃŽÂ ® ÃŽ ¼Ãâ‚¬ÃŽ ¿Ã Ãƒ Ã… ½ ÃŽ ½ÃŽ ± πω: one plate is overriding another, thereby forcing the other into the mantle beneath it.) The opposite form of movement takes place at spreading ridge boundaries. At these boundaries, two plates move away from one another. As the two move apart, molten rock is allowed to rise from the mantle to the surface and cool down to form part of the plates. This, in turn, causes the growth of oceanic crust on either side of the vents. As the plates continue to move, and more crust is formed, the ocean basin expands and a ridge system is created. Divergent boundaries are responsible in part for driving the motion of the plates. At transform fault boundaries, plate material is neither created nor destroyed at these boundaries, but rather plates slide past each other. Transform faults are mainly associated with spreading ridges, as they are usually formed by surface movement due to perpendicular spreading ridges on either side. Earthquake Location When an earthquake occurs, one of the first questions is where was it?. An earthquakes location may tell us what fault it was on and where the possible damage most likely occurred. The hypocentre of an earthquake is its location in three dimensions: latitude, longitude, and depth. The hypocentre (literally meaning: below the center from the Greek υπà Ã…’Î ºÃŽ µÃŽ ½Ãâ€žÃ ÃŽ ¿ÃŽ ½), or focus of the earthquake, refers to the point at which the rupture initiates and the first seismic wave is released. As an earthquake is triggered, the fault is associated with a large area of fault plane. The point directly above the focus, on the earths surface where the origin of an earthquake above ground. The epicentre is the place on the surface of the earth under which an earthquake rupture originates, often given in degrees of latitude (north-south) and longitude (east-west). The epicentre is vertically above the hypocentre. The distance between the two points is the focal depth. The location of any station or observation can be described relative to the origin of the earthquake in terms of the epicentral or hypocentral distances. Propagation of seismic waves Seismic waves are the energy generated by a sudden breaking of rock within the earth or an artificial explosion that travels through the earth and is recorded on seismographs. There are several different kinds of seismic waves, and they all move in different ways. The two most important types of seismic waves are body waves and surface waves. Body waves travel deep within the earth and surface waves travel near the surface of the earth. Body waves: There are two types of body waves: P-waves (also pressure waves) and S-waves (also shear waves). P-waves travel through the Earth as longitudinal waves whose compressions and rarefactions resemble those of a sound wave. The name P-wave comes from the fact that this is the fastest kind of seismic wave and, consequently, it is the first or ‘Primary wave to be detected at a seismograph. Speed depends on the kind of rock and its depth; usually they travel at speeds between 1.5 and 8 kilometers per second in the Earths crust. P waves are also known as compressional waves, because of the pushing and pulling they do. P waves shake the ground in the direction they are propagating, while S waves shake perpendicularly or transverse to the direction of propagation. The P-wave can move through solids, liquids or gases. Sometimes animals can hear the P-waves of an earthquake S-waves travel more slowly, usually at 60% to 70% of the speed of P waves. The name S-wave comes from the fact that these slower waves arrive Secondary after the P wave at any observation point. S-waves are transverse waves or shear waves, so that particles move in a direction perpendicular to that of wave propagation. Depending in whether this direction is along a vertical or horizontal plane, S-waves are subcategorized into SV and SH-waves, respectively. Because liquids and gases have no resistance to shear and cannot sustain a shear wave, S-waves travel only through solids materials. The Earths outer core is believed to be liquid because S-waves disappear at the mantle-core boundary, while P-waves do not. (3: http://www.globalchange.umich.edu/globalchange1/current/lectures/nat_hazards/nat_hazards.html) Surface waves: The surface waves expand, as the name indicates, near the earths surface. The amplitudes of surface waves approximately decrease exponentially with depth. Motion in surface waves is usually larger than in body waves therefore surface waves tend to cause more damage. They are the slowest and by far the most destructive of seismic waves, especially at distances far from the epicenter. Surface waves are divided into Rayleigh waves and Love waves. Rayleigh waves, also known as ground roll, are the result of an incident P and SV plane waves interacting at the free surface and traveling parallel to that surface. Rayleigh waves (or R-waves) took their name from (named for) John Strutt, Lord Rayleigh who first described them in 1885 (ÃŽÂ ® who mathematically predicted the existence of this kind of wave in 1885) and they are an important kind of surface wave. Most of the shaking felt from an earthquake is due to the R-wave, which can be much larger than the other waves. In Rayleigh waves the particles of soil move vertically in circular or elliptical paths, just like a wave rolls across a lake or an ocean. As Rayleigh wave particle motion is only found in the vertical plane, this means that they most commonly found on the vertical component of seismograms. The Rayleigh equation is: Love waves (also named Q waves) are surface seismic waves that cause horizontal shifting of the earth during an earthquake. They move the ground from side to side in a horizontal plane but at right angles to the direction of propagation. Love waves took their name from A.E.H. Love, a British mathematician who worked out the mathematical model for this kind of wave in 1911. Love waves are the result from the interaction with SH-waves. They travel with a slower velocity than P- or S- waves, but faster than Rayleigh waves, their speed relate to the frequency of oscillation. Earthquake size: Earthquake measurement is not a simple problem and it is hampered by many factors. The size of an earthquake can be quantified in various ways. The intensity and the magnitude of an earthquake are terms that were developed in an attempt to evaluate the earthquake phenomenon and they are the most commonly used terms to express the severity of an earthquake. Earthquake intensity: Intensity is based on the observed effects of ground shaking on people, buildings, and natural features. It varies from place to place within the disturbed region depending on the location of the observer with respect to the earthquake epicenter. Earthquake magnitude: The magnitude is the most often cited measure of an earthquakes size. The most common method of describing the size of an earthquake is the Richter magnitude scale, ML. This scale is based on the observation that, if the logarithm of the maximum displacement amplitudes which were recorded by seismographs located at various distances from the epicenter are put on the same diagram and this is repeated for several earthquakes with the same epicentre, the resulting curves are parallel to each other. This means that if one of these earthquakes is taken as the basis, the coordinate difference between that earthquake and every other earthquake, measures the magnitude of the earthquake at the epicentre. Richter defined as zero magnitude earthquake one which is recorded with 1ÃŽ ¼m amplitude at a distance of 100 km. Therefore, the local magnitude ML of an earthquake is based on the maximum trace amplitude A and can be estimated from the relation: ML= log A log A (3) Where A is the amplitude of the zero magnitude earthquake (ML=0). The Richter magnitude scale can only be used when seismographs are within 600 km of the earthquake. For greater distances, other magnitude scales have been defined. The most current scale is the moment magnitude scale MW, which can be used for a wide range of magnitudes and distances. Two main categories of instruments are used for the quantitative evaluation (estimation, assessment) of the earthquake phenomenon: the seismographs which record the displacement of the ground as a function of time, and the accelerographs (or accelerometers) which record the acceleration of the ground as a function of time, producing accelerograms. X the accelerogram of the 1940 El Centro earthquake. For every earthquake accelerogram, elastic or linear acceleration response spectrum diagrams can be calculated. (obtained, estimated) The response spectrum of an earthquake is a diagram of the peak values of any of the response parameters (displacement, acceleration or velocity) as a function of the natural vibration period T of the SDOF system, subjected to the same seismic input. All these parameters can be plotted together in one diagram which is called the tripartite plot (also known as four coordinate paper). 2.2 Earthquake and Structures simulation 2.2.1 Equation of motion of SDOF system Introduction Vibration is the periodic motion or the oscillation of an elastic body or a medium, whose state of equilibrium has been disturbed. ÃŽâ€" ÃŽ ¼Ãâ‚¬ÃŽ ¿Ã Ãâ€° ÃŽ ½ÃŽ ± πω: whose position of equilibrium has been displaced. There are two types of vibrations, free vibration and forced vibration. Vibration can be classified as either free or forced. A structure is said to be in a state of free vibration when it is disturbed from its static equilibrium by given a small displacement or deformation and then released and allowed to vibrate without any external dynamic excitation. Number of Degrees of Freedom (DOF) is the number of the displacements that are needed to define the displaced position of the masses relative to their original position. Simple structures can be idealised as a system with a lumped mass m supported by a massless structure with stiffness k. It is assumed that the energy is dissipated through a viscous damper with damping coefficient c. Only one displacement variable is required in order to specify the position of the mass in this system, so it is called Singe Degree of Freedom (SDOF) system. Undamped Free Vibration of SDOF systems Furthermore, if there is no damping or resistance in the system, there will be no reduction to the amplitude of the oscillation and theoretically the system will vibrate forever.

Description of the Method 3.1 Simplified Multi-Storey Shear Building Model It is almost impossible to predict precisely which seismic action a structure will undergo during its life time. Each structure must be designed to resist at any seismic excitation without failing. For this reason each structure is designed to meet the requirements of the design spectrum analysis based in EC8. Also some assumptions are necessary in order to achieve the best and the simplest idealization for each multi store building. Initially it is assumed that the mass of each floor is lumped at the centre of the floor and the columns are massless. The floor beams are completely rigid and incompressible; hence the floor displacement is being transferred equally to all the columns. The columns are flexible in horizontal displacement and rigid in vertical displacement, while they are provided with a fully fixed support from the floors and the ground. The building is assumed to be symmetric about both x and y directions with symmetric column arrangement. The consequence of this is tha t the centre of the mass of each floor to coincide with the centre of the stiffness of each floor. The position of this centre remains stable up the entire height of the building. Finally, it is assumed that there are no torsional effects for each of the floors. If all the above assumptions are used the building structure is idealised as a model where the displacement at each floor is described by one degree of freedom. Thus, for a jth storey building, j degrees of freedom required to express the total displacement of the building. The roof of the building has always to be considered as a floor. The mass matrix M is a symmetric diagonal nxn matrix for a n-storey building and is given below. Each diagonal value in the matrix represents the total mass of one beam and its two corresponding columns which are assumed to be lumped at each level. M = Stiffness method is used to formulate the stiffness matrix. K is the lateral stiffness of each column and is given by the relationship: K = (22) where EI is the flexural stiffness of a column. The lateral stiffness of each column is clamped at the ends and is imposed in a unit sway. The stiffness of each floor is the sum of the lateral force of all columns in the floor. The stiffness matrix is for a n-storey building is: K = In order to calculate the natural modes of the vibration, the system is assumed that vibrates freely. Thus, g(t)=0, which for systems without damping (c=0) the equation (21) specializes to: M+ Ku = 0 (23) The displacement is assumed to be harmonic in time, this is: = -ω2Ueiωt (24) Hence equation (23) becomes: (K ω2M)U = 0 (25) The above equation has the trivial solution u=0. For non trivial solutions, u≠ 0 the determinant for the left hand size must be zero. That is: |K ω2 M| = 0 (26) This condition leads to a polynomial in terms of ω2 with n roots, where n is the size of matrices and vectors as cited above. These roots are called eigenvalues. By applying the equation (6) (7), the natural frequency and the natural period of vibration for each mode shape can be determined. Each eigenvalue has a relative eigenvector which represent the natural ith mode shape. After the estimation of the eigenvector in order to compare the mode shapes, scale factors are applied to natural modes to standarise their elements associated with various degrees of freedom (X). This process is called normalization. Hence, after the estimation of the eigenvectors each mode is normalised so that the biggest value is X: eigenvector notation. unity. The eigenvectors of a symmetric matrix corresponding to distinct eigenvalues are orthogonal. This aspect is expressed by the following expression: UiTKUij = UiTMUij (27) The classical eigenvalue problem has the following form: (M-1K ÃŽ » I) u = 0 (28) where ÃŽ » =ω2 and I is the identity matrix. EC8 suggests that the response in two modes i and j can be assumed independent of each other when Tj ≠¤ 0.9 Ti where Ti and Tj are the periods of the modes i and j respectively (always Ti ≠¥ Tj). The calculated fundamental period can be checked by the equation that EC8 suggests: T = Ct*H3/4 where T is the fundamental period of the building, Ct is a coefficient and H is the total height of the building; this expression is valid buildings that their total height is not more than forty metres 3.2 Elastic Analysis The response method is used to estimate the maximum displacement (uj), pseudo- velocity (j) and acceleration (j) for each calculated natural frequency. It is assumed that the MDOF system oscillates in each of its modes independently and displacements, velocities and accelerations can be obtained for each mode separately considering modal responses as SDOF responses. Each maximum, displacement velocity and acceleration read from the design spectrum is multiplying by the participation factor ÃŽ ±i to re-evaluate the maximum values expressed ujmax, jmax, jmax respectively. The participation factor ÃŽ ±i is defined by the following equation: (28) where UijT is the transpose vector of each of the mode vectors, M is the mass matrix, AI is the unit vector and Uij is the mode shape vector. The actual maximum displacements of the jth mode are given by: u = ujmaxΆ¡Uj Afterwards, the root-mean-square (RMS) approximation is used in order to calculate the maximum displacement for each floor. In this approach, all the maximum values for each mode, are squared and summed and their square root is derived. If we let Dmax be the maximum displacement then: Dmax = (29) A very variable parameter to characterise the seismic behaviour of a building is the Inter-Storey Drift which can be obtained by the following equation: ÃŽ ´i = Di Di-1/hi (30) where Di, Di-1, are the horizontal displacements for two contiguous floors and hi is the corresponding height of the floor. The calculated values must be lower than 4% in order to agree with the Eurocode. Afterwards the horizontal inertia forces Fjs applied at each floor are obtained by applying the following equation: Fj = MΆ¡UjΆ¡jmax (31) where M is the mass matrix, Uj is the eigenvector for each mode and jmax is the maximum acceleration. As it is suggested from the EC8, the root-mean-approximation is used again in order to obtain the total lateral forces. EC8 suggests that the combined lateral force at each floor is given by the square root of the sum of the squares of each lateral force at each floor of all the modes. If we let Ftotal,i the maximum base shear force then: Ftotal,j = [1] (32) where Fij is the lateral force at floor i of the mode j. Once the total lateral forces and the shear forces have been obtained, the maximum overturning moment is calculated. 3.3 Inelastic Analysis The inelastic response spectra are generally obtained by the scaling of the elastic design spectra via the use of response modification factors. No effect of the energy absorption was assumed in the structure for the calculated values by using the elastic design spectrum. By introducing the ductility factor this parameter is taking into consideration. Newmark has described the ductility parameter ÃŽ ¼ as the ratio of maximum displacement to the displacement at yield. Apparently when yielding does not take place the concept of ductility is not relevant and ÃŽ ¼ is taken equal to unity. ÃŽ ¤he system is described by the damping ratio Ï‚, the natural frequency ωn, and the ductility factor ÃŽ ¼. In order to calculate the new set of values of acceleration, displacement and velocity the design response spectrum has to be constructed. Newmarks procedure leads to the construction of two modified spectra. 1. For maximum acceleration: In this case the elastic design spectrum is reduced by the appropriate coefficients. The acceleration region of the graph is multiplie

Going Back to the Basics :: Teaching Philosophy Education Essays

Going Back to the Basics Education is a very sensitive topic to discuss among adults. Many adults want the education to be based on a system of ideas that is progressive (which is a system high in the aspect of individuality), some want perennialism (which is the teaching of philosophies that have stood the test of time over hundreds of years), and some, like myself, want to take it back to the way it used to be (essentialism). Education as defined by Webster’s Collegiate Dictionary is â€Å"the action or process of education or being educated.† I believe that the way education was presented in the past worked well and that education should remain to be taught the same. For education to be taught the same as it were in the past, many things have to change. There are too many electives being taught in public schools today, there is too much acceptance on certain things like tardiness, absences, and behavior, there are not severe enough punishments for students who break the rules, and the curricula is too easy. To chance this we need to put a strong work ethic into the children and to do that you need a tough and challenging schedule throughout the schooling process. As a physical educator I would do this by not just rolling out a ball and telling the students to â€Å"play†, but by teaching them certain skills it takes to become a physically fit person. In making a person physically fit, you need to teach them the factors of being fit like: how to eat a healthy diet, how to exercise properly, proper hygiene, and how much sleep to get. I think that the only thing that you get out of education, is what you put in it. To become a smart, balanced, and intelligent person you must put forth all effort in getting an education. To the layperson, education is merely something that needs to be done to get through life and â€Å"to get a good job†, but to me education is making yourself into a better person, and a person who knows what they want out of life. I believe that you need not learn all this extra curricula that is being taught in many of today’s schools like philosophy of ideas, mythology, media, and classes like the printing press.

Poetic Analysis of Fern Hill Essay -- Poetry Essays Poem Fern Hill

Poetic Analysis "Fern Hill" Dylan Thomas's poem "Fern Hill" represents the passage of one mans life from boyhood to adulthood and the realization of his mortality. The speaker in this poem uses expressive language and imagery to depict a tale of growing up. The use of colour adds life and character to people and abstract ideas. He looks up to "Time" (313) as an authority figure who has strict control of his life, and with descriptions of biblical figures we can presume that he is a religious person who believes that God is in control of his destiny. Each of these images contributes to a picture of one man's outlook on life and death. Colour imagery is used in the beginning of the poem as the speaker describes his happiness as a child. He explains his young days as being as "happy as the grass is green" (313), or in other words, alive and healthy. He then directly refers himself to being "green and carefree" (313). As a young boy he was vibrant and full of life. Being full of life, like "green grass" (313), means that there is a natural course that life has to follow, birth to death. Anything living has a purpose in life and the speaker reflects his young days as a "Huntsman and Herdsman" (313). The poem takes a dramatic turn when he describes "fire as green as grass" (313). Fire or burning paired with grass means that something destructive has occurred in the speaker's young life that has changed or altered the course of his natural growth. He is an adult when he looks back and says "before the children green" (314). He had gained an understanding that his life is running out and says time held me "green and dying" (313). He is seeing his "green" (314) life turning brown and wilting. He i... ...ruit. Life changing events would alter a child's perspective of himself. "Fern Hill" is a poem about the realization of life and mortality that appears after an unexpected experience occurs. The speaker is moved to a greater wisdom about himself and the world around him. He realizes that the immortality he felt as a child was merely a step towards the unyielding movement of life towards death. Through the use of colour, time, and religious language readers develop an understanding for the speaker's emotions, beliefs, and passage through life. WORKS CITED Orser, Sandi.

Human Sexual Behavior and Sexual Abuse Incest

INCEST Incest  is  sexual intercourse  between family members and close  relatives. [1][2]  The term may apply to sexual activities between individuals of close†blood relationship†, members of the same  household,  step relatives  related by  adoption  or  marriage, or members of the same  clan  or  lineage. [3]  Theincest taboo  is and has been one of the most common of all cultural  taboos, both in current nations and many past societies. [4]  Most modern societies have  laws regarding incest  or social restrictions on closely consanguineous marriages. 5]  In countries where it is illegal, consensual adult incest is seen by some as a  victimless crime. [6][7] In some societies, such as those of  Ancient Egypt  and others, brother–sister, father–daughter, and mother–son, cousin-cousin, aunt-nephew, uncle-niece, and other permutations of relations were practiced among  royalty  as a means of perpetua ting the royal lineage. [8][9]  In addition, theBalinese[10]  and some  Inuit  tribes[11]  have altogether different beliefs about what constitutes illegal and immoral incest. However, parent-child and sibling-sibling unions are almost universally forbidden. 12] Children born of close incestous unions have greatly increased risk of congenital disorders, death and disability at least in part due to genetic diseases caused by the  inbreeding. [13] ————————————————- Terminology The English word  incest  is derived from the Latin  incestus, which has a general meaning of â€Å"impure, unchaste†. It was introduced into  Middle English, both in the generic Latin sense (preserved throughout the Middle English period[14]) and in the narrow modern sense.The derived adjective  incestuous  appears in the 16th century. [15]  Prior to the introduction o f the Latin term, incest was known in  Old English  as  sibbleger  (from  sibb  Ã¢â‚¬Ëœkinship' +  leger  Ã¢â‚¬Ëœto lie') or  m? gh? med  (from  m? g  Ã¢â‚¬Ëœkin, parent' +  h? med  Ã¢â‚¬Ëœsexual intercourse') but in time, both words fell out of use. ————————————————- History Table of prohibited marriages from  The Trial of Bastardie  byWilliam Clerke. London, 1594 ————————————————- Prevalence and statisticsIncest between an  adult  and a person under the  age of consent  is considered a form of  child sexual abuse[36][37]  that has been shown to be one of the most extreme forms of childhood abuse, often resulting in serious and long-term  psychological trauma, especially in the case of parental incest. [38]  Preval ence is difficult to generalize, but research has estimated 10–15% of the general population as having at least one such sexual contact, with less than 2% involving intercourse or attempted intercourse. 39]  Among women, research has yielded estimates as high as 20%. [38] Father-daughter  incest was for many years the most commonly reported and studied form of incest. [40][41]  More recently, studies have suggested that sibling incest, particularly older brothers having sexual relations with younger siblings, is the most common form of incest,[42][43][44][45][46][47][48][49][50]  with some studies finding sibling incest occurring more frequently than other forms of incest. 51]  Some studies suggest that adolescent perpetrators of sibling abuse choose younger victims, abuse victims over a lengthier period, use violence more frequently and severely than adult perpetrators, and that sibling abuse has a higher rate of penetrative acts than father or stepfather incest, w ith father and older brother incest resulting in greater reported distress than stepfather incest. [52][53][54] ————————————————- Types Between adults and childrenMain article:  Child sexual abuse Incest between an adult and a child is usually considered a form of child sexual abuse[55]  and for many years has been the most reported form of incest. Father–daughter and stepfather–stepdaughter incest is the most commonly reported form of adult-child incest, with most of the remaining involving a mother or stepmother. [56]  Father–son incest is reported less often, but it is not known how close the frequency is to heterosexual incest because it is likely more under-reported. 57][58]  Prevalence of incest between parents and their children is difficult to assess due to secrecy and privacy; some estimate that 20 million Americans were, as children, subjected to incest. [56][clarification needed  (needs a better source)] In a 1999 news story,  BBC  reported, â€Å"Close-knit family life in  India  masks an alarming amount of sexual abuse of children and teenage girls by family members, a new report suggests. Delhi organisation  RAHI  said 76% of respondents to its survey had been abused when they were children – 40% of those by a family member. [59] According to the National Center for Victims of Crime a large proportion of  rape  committed in the United States is perpetrated by a family member: Research indicates that 46% of children who are raped are victims of family members (Langan and Harlow, 1994). The majority of American rape victims (61%) are raped before the age of 18; furthermore, 29% of all rapes occurred when the victim was less than 11 years old. 11% of rape victims are raped by their fathers or step-fathers, and another 16% are raped by other relatives. 60] A study of victims of fatherâ €“daughter incest in the 1970s showed that there were â€Å"common features† within families before the occurrence of incest: estrangement between the mother and the daughter, extreme paternal dominance, and reassignment of some of the mother's traditional major family responsibility to the daughter. Oldest and only daughters were more likely to be the victims of incest. It was also stated that the incest experience was psychologically harmful to the woman in later life, frequently leading to feelings of low self-esteem, unhealthy sexual activity, contempt for other women, and other emotional problems. 61][clarification needed  (needs a better source)] Adults who as children were incestuously victimized by adults often suffer from low  self-esteem, difficulties in interpersonal relationships, and  sexual dysfunction, and are at an extremely high risk of many mental disorders, including  depression,  anxiety,  phobic avoidance reactions,  somatoform disorder,   substance abuse,  borderline personality disorder, and  complex post-traumatic stress disorder. 38][62][63]  Research by Leslie Margolin indicates that mother-son incest does not trigger some innate biological response, but that the effects are more directly related to the symbolic meanings attributed to this act by the participants. [64] The  Goler clan  is a specific instance in which child sexual abuse in the form of forced adult/child and sibling/sibling incest took place over at least three generations. [65]  A number of Goler children were victims of sexual abuse at the hands of fathers, mothers, uncles, aunts, sisters, brothers, cousins, and each other.During interrogation by police, several of the adults openly admitted to engaging in many forms of sexual activity, up to and including full intercourse, multiple times with the children. Sixteen adults (both men and women) were charged with hundreds of allegations of incest and sexual abuse of children as young as five. [65] In Japan there is a popular misconception that mother-son incestuous contact in common, due to the manner in which it is depicted in the press and popular media.According to Hideo Tokuoka, â€Å"When Americans think of incest, they think of fathers and daughters; in Japan one thinks of mothers and sons† due to the extensive media coverage of mother-son incest there. [66]  Some western researchers even assumed this was established fact. However, research into victimization statistics from police and health care systems discredits this, as it shows the vast majority of sexual abuse, including incest, is perpetrated by men against young girls. 67]  The Mainichi Daily News  column  WaiWai, by Australian journalist Ryann Connell, featured often-sensationalist stories, principally translated from and based on articles appearing in Japanese tabloids. [68]  On June 28, 2008, Mainichi announced punitive measures. [69][70][71]  Mainichi said, â€Å"We contin ued to post articles that contained incorrect information and indecent sexual content. These articles, many of which were not checked and properly investigated should not have been dispatched.We apologize deeply for causing many people trouble and for betraying the public's trust in the Mainichi Shimbun. †Ã‚  [72] Between childhood siblings Childhood sibling–sibling incest is considered to be widespread but rarely reported. [56]  It is believed to be the most common form of intrafamilial abuse. [73] Sibling-sibling incest becomes  child-on-child sexual abuse  when it occurs without consent, without equality, or as a result of  coercion. The most commonly reported form of abusive sibling incest is abuse of a younger sibling by an older sibling. 56]  A 2006 study showed a large portion of adults who experienced sibling incest abuse have distorted or disturbed beliefs (such as that the act was â€Å"normal†) both about their own experience and the subject of sexual abuse in general. [74] Sibling abusive incest is most prevalent in families where one or both parents are often absent or emotionally unavailable, with the abusive siblings using incest as a way to assert their power over a weaker sibling. [75]  Absence of the father in particular has been found to be a significant element of most cases of sexual abuse of female children by a brother. 76]  The damaging effects on both childhood development and adult symptoms resulting from brother–sister sexual abuse are similar to the effects of father–daughter, including substance abuse, depression, suicidality, and eating disorders. [76][77] Between consenting adults Sexual activity between adult close relatives may arise from  genetic sexual attraction. [78]  This form of incest has not been widely reported in the past, but recent evidence has indicated that this behavior does take place, possibly more often than many people realize. 78]  Internet  chatrooms  and topical websites exist that provide support for incestuous couples. [78] Proponents of incest between consenting adults draw clear boundaries between the behavior of consenting adults and rape, child molestation, and abusive incest. [78]  According to one incest participant who was interviewed for an article in  The Guardian: â€Å"You can't help who you fall in love with, it just happens. I fell in love with my sister and I'm not ashamed †¦ I only feel sorry for my mom and dad, I wish they could be happy for us. We love each other.It's nothing like some old man who tries to fuck his three-year-old, that's evil and disgusting †¦ Of course we're consenting, that's the most important thing. We're not fucking perverts. What we have is the most beautiful thing in the world. â€Å"[78] In  Slate Magazine,  William Saletan  drew a legal connection between gay sex and incest between consenting adults. [79]  As he described in his article, in 2003, U. S. Senato r  Rick Santorumcommented on a pending U. S. Supreme Court case involving sodomy laws (primarily as a matter of  Constitutional rights to Privacy and Equal Protection under the Law).He stated: â€Å"If the Supreme Court says that you have the right to consensual sex within your home, then you have the right to bigamy, you have the right to polygamy, you have the right to incest, you have the right to adultery. â€Å"[79]  However, David Smith of the  Human Rights Campaign  professed outrage that Santorum placed being gay on the same moral and legal level as someone engaging in incest. Saletan argued that, legally and morally, there is essentially no difference between the two, and went on to support incest between consenting adults being covered by a legal right to privacy. 79]UCLA  law professor  Eugene Volokh  has made similar arguments. [80]  In a more recent article, Saletan said that incest is wrong because it introduces the possibility of irreparably damagi ng family units by introducing â€Å"a notoriously incendiary dynamic—sexual tension—into the mix†. [81] Aunts, uncles, nieces or nephews In Florida, consensual adult sexual intercourse with someone you know to be your aunt, uncle, niece or nephew constitutes a felony of the third degree. [82]  Other states also commonly prohibit marriages between such kins. [83]  The legality of sex with a half-aunt or half-uncle varies state by state. 84] Between adult siblings The most public case of consensual adult sibling incest in recent years is the case of a brother-sister couple from Germany,  Patrick Stubing  and Susan Karolewski. Because of violent behavior on the part of the father, the brother was taken in at the age of 3 by foster parents, who adopted him later. At the age of 23 he learned about his biological parents, contacted his mother, and met her and his then 16 year old sister for the first time. The now-adult brother moved in with his birth family shortly thereafter.After their mother died suddenly six months later, the couple became intimately close, and had their first child together in 2001. By 2004, they had four children together: Eric, Sarah, Nancy, and Sofia. The public nature of their relationship, and the repeatedprosecutions  and even jail time they have served as a result, has caused some in Germany to question whether incest between consenting adults should be punished at all. An article about them in  Der Spiegel  states that the couple are happy together. According to court records, the first three children have mental and physical disabilities, and have been placed in foster care. 6]  In April 2012, at the  European Court of Human Rights, Patrick Stuebing lost his case that the conviction violated his right to a private and family life. [85][86] Cousin relationships See also:  Cousin marriage  and  List of coupled cousins Marriages and sexual relationships between first cousins are stigmatized a s incest in some western cultures, but tolerated in most of the world. Currently, 24 states  US states, prohibit marriages between first cousins and another seven permit them only under special circumstances. 87]  Cousin marriages are rare, accounting for less than 1% of marriages in Western Europe, North America and Oceania, while reaching 9% in South America, East Asia and South Europe and up to 25% in regions of the Middle East, North Africa and South Asia. [88]  Communities such as the Dhond and the  Bhittani  of Pakistan clearly prefer marriages between cousins as believe they ensure purity of the descent line, provide intimate knowledge of the spouses, and ensure thatpatrimony  will not pass into the hands of â€Å"outsiders†. 89] Apart from the partial prohibition in the United States, there are some cultures in Asia which stigmatize cousin marriage, in some instances even marriages between second cousins or more remotely related people. This concerns notab ly the culture of  Korea, and some  Hindu  communities in India. In South Korea, before 1997, anyone with the same last name and clan were prohibited from marriage. In light of this law being held unconstitutional, South Korea now only prohibits up to third cousins (see  Article 809 of the Korean Civil Code).Hmong  culture prohibits the marriage of anyone with the same last name – to do so would result in being shunned by the entire community, and they are usually stripped of their last name. In  Western Australia  over 500 marriages are between cousins. In a review of 48 studies on the children parented by cousins, most of the babies born to cousins were healthy contrary to the popular perception, with birth defects being 4% of births for consanguineous couples as opposed to 2% for the general population. [90]  Inbreeding over many generations does increase risks however. citation needed] Incest defined through marriage Some cultures include relatives by marr iage in incest prohibitions; these relationships are called  affinity  rather than  consanguinity. For example, the question of the legality and morality of a widower who wished to marry his  deceased wife's sister  was the subject of long and fierce debate in the  United Kingdom  in the 19th century, involving, among others,  Matthew Boulton. [91][92]  In medieval Europe, standing as a  godparent  to a child also created a bond of affinity. citation needed]  But in other societies, a deceased spouse's sibling was considered the ideal person to marry. The Hebrew Bible forbids a man from marrying his brother's widow with the exception that, if his brother died childless, the man is instead required to marry his brother's widow so as to â€Å"raise up seed to him† (taken from Deuteronomy 25:5–6). According to Islamic ideology, marriage among close blood relations like parents, siblings, the children of siblings, aunts and uncles is prohibited. Fir st or second cousins may marry.Marrying the widow of a brother, or the sister of deceased or divorced wife is allowed in Islam. ————————————————- Inbreeding Main article:  Inbreeding Incest that results in offspring is a form of close  inbreeding  (reproduction between two individuals with a common ancestor). Inbreeding leads to a higher probability of  congenital birth defectsbecause it increases that proportion of zygotes that are  homozygous, in particular for deleterious  recessive alleles  that produce such disorders[93]  (and see  Inbreeding depression#Inbreeding depression and natural selection).Because most such alleles are rare in populations, it is unlikely that two unrelated marriage partners will both be heterozygous carriers. However, because close relatives  share a large fraction of their alleles, the probability that any such rare delete rious allele present in the common ancestor will be inherited from both related parents is increased dramatically with respect to non-inbred couples. Contrary to common belief, inbreeding does not in itself alter allele frequencies, but rather increases the relative proportion of homozygotes to heterozygotes.However, because the increased proportion of deleterious homozygotes exposes the allele to  natural selection, in the long run its frequency decreases more rapidly in inbred population. In the short term, incestuous reproduction is expected to produce increases in spontaneous abortions of zygotes, perinatal deaths, and postnatal offspring with birth defects. [94] There may also be other deleterious effects besides those caused by recessive diseases. Thus, similar  immune systems  may be more vulnerable to infectious diseases (see  Major histocompatibility complex and sexual selection). 95] A 1994 study found a mean excess mortality with inbreeding among first cousins of 4. 4%. [96]  Children of parent-child or sibling-sibling unions are at increased risk compared to cousin-cousin unions. Studies suggest that 20-36% of these children will die or have major disability due to the inbreeding. [13]  A study of 29 offspring resulting from brother-sister or father-daughter incest found that 20 had congenital abnormalities, including four directly attributable to autosomal recessive alleles. 97] ————————————————- Animals Main article:  Animal sexual behavior Many mammal species including humanity's closest  primate  relatives tend to avoid close inbreeding, especially if there are alternative partners available. [98]  However some chimpanzees have been recorded attempting to mate with their mothers. [99]  Male rats have been recorded engaging in mating with their sisters, but they tend to prefer non-related females over their sister s. 100] Livestock  breeders often practice controlled breeding to eliminate undesirable characteristics within a population, which is also coupled with  culling  of what is considered unfit offspring, especially when trying to establish a new and desirable trait in the stock. ————————————————- In popular culture Main article:  Incest in popular culture Incest is a somewhat popular topic in English  erotic fiction; there are entire collections and websites devoted solely to this genre, with an entire genre of pornographic  pulp fiction  known as â€Å"incest novels†. ———————————————— Laws Main article:  Laws regarding incest Incest is illegal in many jurisdictions. The exact legal definition of â€Å"incest,† including the nature of t he relationship between persons, and the types sexual activity, varies by country, and by even individual states or provinces within a country. These laws can also extend to marriage between subject individuals. In most places, incest is illegal, regardless of the ages of the two partners. In other places, incestuous relationships between two consenting adults (with the age varying by location) are permitted.Such countries where it is permissible and legal, includes for example the  Netherlands,  France, and  Spain. In  Sweden  the only type of incestuous relationship allowed by law is that between half-siblings and they must seek government counseling before marriage. [101] A jurisdiction's definition of an incestuous relationship will also limit who a person is permitted to marry. Some jurisdictions forbid first-cousins to marry, while others limit the prohibition to brothers, sisters, mothers, fathers, aunts and uncles. ——————â €”—————————- [edit]Religious views edit]Jewish Main articles:  Incest in the Bible  and  Jewish views on incest In three places in the  Torah, there are lists of family members between whom it is prohibited to have sexual relations; each of these lists is progressively shorter. The biblical lists are not symmetrical – the implied rules for women and men are not the same. Relationships compare as follows:   Ã‚  Forbidden for men Forbidden for women Forbidden for both men and women | Holiness Code| Deuteronomic Code| | Leviticus 18| Leviticus 20| | Grandparent's spouse (including other grandparent)| | | | Parent's spouse| Parent| | | | Stepparent| | | | Parent-in-law| | | | Uncle/aunt| Parent's sibling| | | | | Uncle's/aunt's spouse| Father's sibling's spouse| | | | | | Mother's sibling's spouse| | Parent's child| Half-Sibling (mother's side)| | | | | Father's child| Sibling| | | | | | Half-sibling (fa ther's side)| | | | Step sibling| | Sibling-in-law (if the spouse was still alive)| | | | Nephew/niece| Sibling's child| | | | | Nephew/niece-in-law| Spouse's brother's child| | | | | | Spouse's sister's child| | Spouse's child| Child| | | | | Stepchild| | | | Child-in-law| | | |Spouse's grandchild (including grandchild)| | | | Apart from the questionable case of the daughter, the first incest list in the Holiness code roughly produces the same rules as were followed in early (pre-Islamic) Arabic culture;[102]  in  Islam, these pre-existing rules were made statutory. [103] In the 4th century BCE, the  Soferim  (scribes) declared that there were relationships within which marriage constituted incest, in addition to those mentioned by the Torah. These additional relationships were termed  seconds  (Hebrew:  sheniyyot), and included the wives of a man's grandfather and grandson. 104]  The classical rabbis prohibited marriage between a man and any of these  seconds   of his, on the basis that doing so would act as a  safeguard  against infringing the biblical incest rules,[105]  although there was inconclusive debate about exactly what the limits should be for the definition of  seconds. [102] Marriages forbidden in the Torah were regarded by the rabbis of the Middle Ages as invalid – as if they had never occurred;[106]  any children born to such a couple were regarded as  Jewish bastards,[106]  and the relatives of the spouse were not regarded as forbidden relations for a further marriage. 107]  On the other hand, those relationships which were prohibited due to qualifying asseconds, and so forth, were regarded as wicked, but still valid;[106]  while they might have pressured such a couple to divorce, any children of the union were still seen as legitimate. [106] Christian In the Roman Catholic Church, marriage is generally not permitted if the potential spouses are related in the collateral line up to and including the second degree, although a dispensation may be granted permitting marriages etween first cousins or even uncle/niece unions as in the marriage of Leopold I, Holy Roman Emperor to his niece, and first cousin, Margarita Teresa of Spain in 1666. [citation needed]  The Church does not generally permit the marriage if a doubt exists on whether the potential spouses are related by consanguinity in any degree of the direct line or in the second degree of the collateral line. [108] In the  Eastern Orthodox Church, marriages are banned between second cousins or closer and between second uncles / aunts and second nieces / nephews (between first cousins once removed) or closer.Also, marriages that produce children that are closer genetic relatives than legal are also not permitted (unless the genetic relationship does allow marriage between those children). For example, two siblings may not marry two other siblings because legally their children will be cousins, but genetically they'll be half-siblings. On the other hand, two siblings may marry two cousins. [citation needed] The  Anglican Communion  allows marriages up to and including first cousins. But in all of the three preceding Christian churches, marriages to uncles, aunts, relatives in the direct line, or their respective spouses are not allowed. citation needed] Islamic Main article:  Mahram The  Quran  gives specific rules regarding incest, which prohibit a man from marrying or having sexual relationships with: * his father's wife[109]  (his mother,[110]  or stepmother[110]), his mother-in-law, a woman from whom he has nursed, even the children of this woman[110] * either parent's sister (aunt),[110] * his sister, his half sister, a woman who has nursed from the same woman as he, his sister-in-law (wife's sister) while still married. Half relations are as sacred as are the full relations. 110] * his niece (child of sibling),[110] * his daughter, his stepdaughter (if the marriage to her mother had been  consummated), his daughter-in-law. [110]| The main differences (apart from relationships between a man and his daughter) are: * a woman from  whom he has nursed * a woman who has  nursed from the same woman  as he * a niece| A  Hadith  also prohibits marriage to a woman and her parent's sister at the same time. [111]  The same applies for a woman with the male counterparts to the aforementioned. [edit]HinduHinduism  speaks of incest in abhorrent terms. Hindus are fearful of the bad effects of incest and thus practice strict rules of both  endogamy  and  exogamy  within  castes  (Varna) but not in the same family tree (gotra) or bloodline (Pravara). Marriages within the gotra (â€Å"swagotra† marriages) are banned under the rule of exogamy in the traditional matrimonial system. [112]  People within the gotra are regarded as kin and marrying such a person would be thought of as incest. i. e. Marriage with paternal cousins is strictly proh ibited. 113]  In fact marriage between two people whose parents are related paternally up to seven generations is expressly prohibited. Gotra is transferred down the male lineage while the Gotra of a female changes upon marriage. i. e. , upon marriage a woman belongs to her husband's Gotra and no longer belongs to her father's Gotra. Hence marriage with a person having same Gotra as of the original  Gotras  of grandparents is prohibited[citation needed]. Nevertheless, in  Tamil Nadu  of Southern India, Marriage with maternal cousins and marriages between Maternal Uncle and Niece were widely in practice a few decades back.However the tradition of getting married to maternal uncle has declined considerably now and may soon become a relic of the past. In matrilinial societies of  Kerala  marriage between first cousins were common. It is said to have helped in preserving family wealth. Buddhist Buddhist  societies take a strong ethical stand in human affairs and sexual b ehavior in particular. Most variations of Buddhism decide locally about the details of incest as a wrongdoing, according to local cultural standards. [114]  Sexual misconduct is mentioned but the definition of what constitutes misconduct sex is an individual issue. 115]  The most common formulation of Buddhist ethics are the  Five Precepts  and the  Noble Eightfold Path: one should neither be attached to nor crave sensual pleasure. These precepts take the form of voluntary, personal undertakings, not divine mandate or instruction. The third of the Five Precepts is â€Å"To refrain from committing sexual misconduct†. ‘Sexual misconduct' means any sexual conduct involving violence, manipulation or deceit – conduct that therefore leads to suffering and trouble. [116]  Buddhist monks and nuns strictly forbid any type of sexual misconduct but incest is not specifically efined as sexual misconduct, and therefore depends on the culture of the area, not on ma ndate from Buddhism itself. However, there are no enforced rules for laypeople in Buddhism, only guidance. Incest Incest  is sexual contact between persons who are so closely related that their marriage is illegal (e. g. , parents and children, uncles/aunts and nieces/nephews, etc. ). This usually takes the form of an older family member sexually abusing a child or adolescent. Laws vary from place to place regarding what constitutes incest, child sexual abuse, sexual assault, and rape. How common is Incest?There are very few reliable statistics about how often incest occurs. It’s difficult to know how many people are affected by incest because many incest situations never get reported. There are many reasons that the victim might not report the abuse. * The victim has been told that what is happening is normal or happens in every family, and doesn’t realize that it is a form of abuse * The victim may not know that help is available or who they can talk to * The victi m may be afraid of what will happen if they tell someone * The abuser may have threatened the victim The victim may care about the abuser and be afraid of what will happen to the abuser if they tell * The victim may be afraid of what will happen to them if they tell * The victim may also be concerned about how many people will react when they hear about the abuse * They may be afraid that no one will believe them or that the person they confide in will tell the abuser * The victim may be afraid that people will accuse them of having done something wrong What makes Incest different than child sexual abuse?All forms of child sexual abuse can have negative long-term effects for the victim. You can read about some of those effects  here. Incest is especially damaging because it disrupts the child’s primary support system, the family. * When a child is abused by someone outside the family, the child’s family is often able to offer support and a sense of safety. * When the abuser is someone in the family, the family may not be able to provide support or a sense of safety.Since the children (especially younger children) often have limited resources outside the family, it can be very hard for them to recover from incest * Incest can damage a child’s ability to trust, since the people who were supposed to protect and care for them have abused them. * Survivors of incest sometimes have difficulty developing trusting relationships * It can also be very damaging for a child if a non-abusing parent is aware of the abuse and chooses—for whatever reason—not to take action to stop it. * There are many reasons that a non-abusing parent might not stop the abuse. The non-abusing parent may feel that they are dependent on the abuser for shelter or income. * If the non-abusing parent was the victim of incest as a child, they may think that this is normal for families. * The non-abusing parent may feel that allowing the incest to continue is the only way to keep their partner. * The non-abusing parent may feel that their child was â€Å"asking for it† by behaving in ways that the parent perceives as provocative or seductive. * Unfortunately, many non-abusing parents are aware of the incest and choose not to get their child out of the situation, or worse, to blame their child for what has happened.This makes the long-term effects of incest worse. INCEST Liberalisation and the development of society have led to many forms of sexuality to be accepted. Something which was considered as scandalous is now more or less normal. If you search the term â€Å"incest† online, you will get the impression that this is yet another variation of normal human sexuality. Still, scientists claim that incest is sexual perversion which often signalises the family`s dysfunctional trait. Incest usually occurs in socially isolated families and points to pathologic relations within the family. What is it and what are its consequences? Incest  is defined as sexual intercourse or any form of sexual activity between closely related persons, especially within the immediate family. Incest between an adult and a child is known asinterfamilial child sexual abuse. – Even one third of child abusers are the parent or their spouse which is not the child`s birth parent. Relatives or close family friends are the abuser in 85 percent of child sexual abuse cases – doctor Gordana Buljan Flander told us. Children who suffered such sexual abuse have serious and long-term psychological damage, especially if parental incest is in question.Adults who experienced incest in their childhood tend to suffer from low self-esteem, they have difficulties in interpersonal relationships, sexual dysfunction and are at an extremely high risk of many mental disorders, experts claim. Variations to the theme There are several types of incest: Parent-child  is one of most common types of incest and statistics show it is usually fat her-daughter or stepfather-daughter incest. Other reports include mother-son incest or stepmother-son incest, while father-son incest is rarely reported. Sibling incest  is considered to be widespread, although experts believe it is rarely reported.Research conducted by scientist Floyd Martinson at an American university yielded interesting results. 10-15 percent of students admitted to having sexual experience with a brother or sister. Of those, 30% reported negative reactions and 30% reported positive reactions. A similar study conducted in 1993 in the USA showed that 16 percent out of 930 adults were sexually abused by their brother or sister before turning 18. This form of incest is often reported in families where the parents are often absent or are emotionally unavailable.Apart from these forms, there is incest that occurs between  cousins. Some countries believe marriage or sexual relationship of a widow/widower and a brother or sister of the deceased spouse is somewhat i ncestuous. – Psychiatry puts incest next to paraphilia, i. e. pathologic sexual activities which is a group name for every sexual activity that is considered unnatural in psychology and sexology. Apart from incest, paraphilia also includes paedophilia, sadism, masochism, sexual fetishism, exhibitionism, voyeurism, necrophilia, nymphomania†¦ Some are legally regulated, others are not.Also, there is a thin line for some: if unusual sexual activity is in question which the majority of people do not practice, a sexual disorder or behaviour which is morally condemned by the society – said doctor Domagoj Stimac, psychiatrist of Zagreb`s Policlinic for the protection of children. Why does incest happen? Science has not yet determined what makes people attracted to one person and repelled by others. – Sexual attraction is largely credited  to something we all know as `brain chemistry`, i. e. the central nervous system.Also, upbringing and earliest childhood exper ience affects who we will be attracted to. Still, scientists have yet to determine the exact `cause` why we are attracted to some people – doctor Stimac told us. Not fantasy, but reality There is a new case of incest in the media every  now and then, reminding us of the fact that it is an actual occurrence and not something that happens somewhere else. At the beginning of last year, a German court sentenced a 38-year-old man to 2 years and 3 months in prison for forcing his wife to have sexual intercourse with their teenage son.The first time she slept with him, he was only 15. After several times she was forced to have sexual intercourse, the wife reported the case to the police. What if love is in question? Recently, a story was published in Germany about a brother and sister, Susan (22) and Patrick (29), who are living together and have 4 children. Despite the fact Patrick has spent more than 2 years in prison and the environment cannot accept them, they are fighting to legalise their relationship and think banning incest means â€Å"denying sexual freedom†. They love each other and want to live together in a real marital union.Although aware their love is unusual to say the least, they do not want to give it up. Another case is a sexual-love affair between 61-year Australian and his 39-year-old daughter, who made their relationship public during a TV show when their daughter was born. – Incest is actually much more common than we would think, i. e. hope. It is more common in primitive societies, but it is still present in developed ones. This can be concluded from so called xxx websites, which offer us stories, photos and films with incestuous sexual relations.Still, incest is still a taboo, few people dare to openly speak about it – doctor Domagoj Stimac believes. INCEST Incest is one of the most interesting taboos of our time. The definition of incest is a highly controversial topic. Yet, the definition of incest is one of t he most important definitions for the people involved, though the legal and psychological meanings are not much the same. Incest needs to be similarly defined for the incestuous parties, both by the law and by psychologists. The definition of incest should be determined by the cases of incest.The people who commit incest and the types of incest should be considered when making this definition for the law. Why incest occurs has a great deal to do with the people and the types of incest. With the definition dissimilar between the law and psychologists, it is very difficult for the involved to do anything about it. The definition is both stated as wrong by law and by most religious morals. According to psychologists, incest is defined as: A) any intimate physical contact that is sexually arousing between non-married members of a  family. Justice, pg 25) What this is interpreted as is that sexual intercourse does not need to occur for a situation to be considered incestuous. Stroking, fondling, or even intimately kissing can be considered incest. This is not all true for the legal definition. In Georgia, incest is defined as any sexual intercourse between known relatives, by blood or by marriage, (meaning a step-parent and step-child. ) Incest laws basically exist to prohibit marriage or inbreeding between family members, and the sentences are almost never carried out. Kosof, pg 53) So incest is stated as wrong, but not enforced. The Bible states that incest is wrong, just as the law does. A Cursed be he who has relations with his father’s wife†¦ Cursed be he who has relations with his sister or half-sister! (Deu 27:20,22. )  Therefore, the definition can be altered to fit the needs of the definer. The different forms of incest are as follows: father-daughter, mother-son, brother-sister, and father-son. Conditions of incest don’t always involve intercourse, but still hurt the included. So, the conditions should help to define the firm meanin g. But surely at fourteen, I should have been capable of escaping†¦Ã¢â‚¬  (Armstrong, pg 7)Father-daughter is the most common form of incest. Three-fourths of all reported cases usually involve dad and his oldest daughter. It is usually non-violent, and the daughters usually feel unattached to their mothers. (Kempe, pgs 48-51) Sometimes the daughter may act in a seductive manner toward her father, or the father might act as a big brother forcing his little sister to misbehave. (Armstrong, pg 235) If the daughter is seductive, then she might gain power over her father.This is not always true for mother-son incest. Mother-son incest is usually brought on as a way to highly express love, â€Å"sex education†, or the mother is promiscuous. If the mother feels like she is expressing her love to her son, then she uses sex as a means of closeness. (Justice, pg 102) There is either no husband or a passive husband. The mother can be very seductive and encourage the son to have s ex with her and limits the son’s social life. She acts on a â€Å"don’t leave me† attitude to keep her son tied down. Sometimes the son gets aroused my his mother and then becomes the aggressor. Justice, pg 103) If he isn’t attracted to mom, why not be attracted to his sister? This is the case in brother-sister, or sibling incest. It is less traumatic and the male participant may be proud about it. The brothers can become violent and force their sister to join in, although usually the sister is willing to participate. (Justice, pg 105) When both of the children are shy, the girl sees him as the only boyfriend she will ever have and becomes flirtatious. The two could also have mutual admiration, and then become sexually attracted to each other.This leads into the most rarely reported incest of the four. Father-son incest is rarely reported because it violates two taboos, homosexuality and incest. (Justice, 196) Males want to protect their masculinity, so t hey will not tell anyone. They pretend to like girls, and they date them, but tend to be attracted to boys. When they move out of the house, they sometimes choose to be a male prostitute. The fathers can be alcoholic and very abusive. The fathers of any incestuous relationship can have psychopathic or symbiotic personalities.Him who has a psychopathic personality seeks  stimulation, and has a â€Å"get even† aggressiveness. No feelings of guilt and a powerful need for aggression seem to happen often in most cases. â€Å"I literally could not walk out of the house without my father wanting to know where I was going, with whom, and when I would be back. †(Kosof, pg 17) He may be promiscuous or pansexual, (meaning that all he can think about is sex. Everything is a sex object to him. ) (Justice, pgs 83-85) The father with a symbiotic personality hungers for intimacy. The only way of expression he knows is through sex.There are four types of symbiotic personalities. The introvert, the rationalizer, the tyrant, and the alcoholic. The introvert is very protective toward his family and fells Aunder attack. â€Å"He cannot trust people and is easily disappointed. † The wife usually denies him sex. The rationalizer shows what â€Å"love† is, or teaches â€Å"sex education† to his daughter. The tyrant is the authoritarian; he uses threats and physical force to get what he wants. He pretends to have everything under control and hides the problem at home. His daughter â€Å"owes† him sex.He is very jealous and paranoid. The alcoholic is a dependant, although he tries to hide it. 10-15% of incest committers are alcoholics. Mothers share most of the characteristics of the father. The mothers may be promiscuous and long to be taken care of. Incest might begin as innocent sleeping with her son and then drifts into more physical things. She is not likely to have intercourse with her son, but she implies that someday she will give her self fully to the son, which can lead to the son being a violator, which is rare because the children of incest are mostly victims. Justice, pg 145)†Sex is not sex for the incest survivor. † (Blume, pg 207) Different children of incest act in different ways. It mainly depends on how the incest was brought about. Some may act untouched by the experience and seldom are able to defend themselves. When they reach adulthood, the might start experiencing flashbacks or amnesia. They live in denial and have an emotional shutdown. (Blume, pg 322) Sometimes they result in schizophrenia or multiple personality disorders. They also seem to have sexual shutdowns and are uncomfortable with it. But why does this occur?Incest usually occurs when sex stops between mother and father. Mom either denies dad sex, there is a major life crisis, or opportunity knocks. The opportunity for incest occurs when mother is gone all the time and so the daughter assumes the role of the mother. When this happens, there is a need for treatment. This is when the definition of incest is most important. The children are very scared and need confidence. If he/she tells a psychologist or teacher, that person is required by law to tell the authorities. (Kosof, pg 53) When the authorities are contacted, the definition comes into play.The child wants to feel safe, and if their definition of incest doesn’t live up to the law’s, then the charges could be dropped and the child gets into more problems with incest. Therefore, the background of the incest is very important to the law’s definition. By the people involved, the form, and why it occurs are critical to helping the child out when defining the term. The definition of incest by the law should be closer to the definition of psychologists in order to help out the family. â€Å"It is evident that we still know very little about how to treat the sexual offender and the abused child effectively. † (Kempe, pg 109)
