Hip Hop :: Rap Music Hip-hop essays research papers

Hip-hop as a musical form began among the youth of South Bronx, New York in the mid- 1970’s. Individuals such Kool Herc and Grandmaster Flash were some of the early pioneers of this art form.(Fernando 43) Through their performances at clubs and promotion of the music, hip-hop consistently gained in popularity throughout the rest of the 1970’s. The first commercial success for hip-hop was a song â€Å"Rapper's Delight† by the Sugar Hill Gang in 1979.(Potter 45) This helped bring hip-hop into the national spotlight. The 1980’s saw the continued success of hip-hop with many artists such as Run DMC (who had the first rap album to go gold in 1984), L.L. Cool J, Fat Boys, and west coast rappers Ice-T and N.W.A becoming popular. Today, in the late 1990’s rap music continues to be a prominent and important aspect of African- American culture. Hip-hop was a way for youths in black inner city neighborhoods to express what they were feeling, seeing, and living and it became a form of entertainment. Hanging out with friends and rapping or listening to others rap kept black youths out of trouble in the dangerous neighborhoods in which they lived. The dominant culture did not have a type of music that filled the needs of these youth, so they created their own. So, hip-hop originally emerged as a way "for [black] inner city youth to express their everyday life and struggles" (VOT, 125). Hip-hop is now seen as a subculture that, includes a large number of middle to upper white class youths, which have grown to support and appreciate it. Many youth in America today are considered part of the hip-hop subculture because they share a common love for a type of music that combines catchy beats with rhythmic music and thoughtful lyrics to create songs with a distinct political stance. Hip-hop lyrics are about the problems rappers have seen, such as poverty, crime, violence, racism, poor living conditions, drugs, alcoholism, corruption, and prostitution. These are serious problems that many within the hip-hop subculture believe are being ignored by mainstream America. Those within the subculture recognize and acknowledge that these problems exist. Those within this subculture consider "the other group" to be those people who do not understand hip-hop and the message its artists are trying to send. The suppresser, or opposition, is the dominant culture, because it ignores these problems and perhaps even acts as a catalyst for some of them.

Controversial novels Essay

Argued to be one of Hardy’s most controversial novels, published in 1891 during an era when the underprivileged classes of society, were submissive to superstitious beliefs in particular those such as luck spiritual beings and ultimately fate which were the foundations of lower class civilisation, Tess of the D’Urbervilles presents a story of Fate toying with the life of the Heroine Tess. Fate is an influential part of the plot because it is what dictates her life. Events in the beginning of the novel begin a domino effect that cannot be reverse, thus Her fate is already chosen and all she can do is live through the events that happen to her. Whilst Walkers Colour purple is written during an era of gender social and racial inequalities narrated through Celie whose life consisting of an abundance of obstacles refuses to give into the Fate which determined the lives of poor uneducated black females during the 1930s. What exactly is Fate, is it in our personalities, actions and character or are our lives controlled by a supposed force or power which predetermines events in our life’s, meaning regardless of what we do we are unable to change our destiny. This theme is explored thoroughly by Thomas Hardy through his heroine Tess who is portrayed as a victim of fate throughout the novel, chance and coincidence bring about disasters in the novel that we can claim occur due to fate, it appears the main characters are subject to forces beyond their control. The author employs a very fatalistic plot throughout the novel making Tess endure whatever is thrown at her . In the first chapter of the book the horse Prince dies, this is seen as Tess’ fault as she falls as sleep due to being exhausted, this happens at night when the weather is very depressed. Hardy uses pathetic fallacy by claiming the ‘atmosphere’ was pale, this makes the reader feel tension and also an expectation of tragedy . This scene is similar to that of the one at the chase when Alec finds Tess unconscious and may have raped her which is ultimately up to speculation. It is clear that Hardy uses the death of prince to create a sense of foreboding as this episode and the one at the chase are extremely similar, on both occasions Tess has fallen asleep due to tiredness and also the weather is used as an indication for what is to follow. From this we can question whether these events are down to fate and also ask if Hardy pre-determines Tess’ fate and future through her early actions thus her future is unalterable so there is nothing she can do to change. This has lead to the critic The Irvine Howe has writing: ‘May we see her purely as a victim, like the white horse, the pheasants, the animals who are killed at harvest time? Hers is a poor wounded name’ This supports The interpretation that Tess’ life was controlled by Fate the just like the events in the novel such as the horses death and the death of the pheasants which all acted as a sense of foreboding and events which pre determine Tess death. Towards the latter stages of the novel during chapter 46, Hardy again emphasises the significant role Fate has played in Tess’ life and misfortunes. Firstly at the bottom of page 320 Tess states†¦ â€Å"How can I pray for you?†¦ When I am forbidden to believe that the great power who moves the world would alter his plans on my account? † Tess is telling Alec that she has lost her belief in God as her prayers do not move him. Therefore she is indicating this is happening because God already has his plans made and what she wants makes no difference because she is not important enough for him to change them, thus empowering the element of Fate and it’s restrictions on her ability to change. Alice Walker, author of ‘The Colour Purple’ approaches the theme of Fate and destiny in a similar way to Hardy to a certain extent, in ‘The Colour Purple’ the character Celie goes through a series of events at the beginning of the novel, she is raped by her father on several occasions is forced to give away the children that she conceived through him then her sister Nettie is forced to leave the home in which Celie lives due to her Husband Mr†¦ , but later on in the novel we learn that Nettie is now living with the family that adopted her sister’s children. This shows that Alice Walker purposely portrayed Celie’s life as a victim of Fate, but gives her character an opportunity to resist this fate which results in a positive outcome for Celie. Its possible to say that Walker highlights the fact that although we may be victims of Fate we are able to control this Fate and our, she does this by showing that Celie is in fact not a victim of fate and unlike Tess her own actions are what allow her to change her destiny. We can say this because Celie confides in God through her letters, giving her hope and belief and she restrains herself from killing the man who has brought her pain and suffering, Mr†¦ , unlike Tess . Celies ability to change and prevent Fate from controlling her life is ultimately down to the letters she writes to God, she tells her sister Nettie†¦ â€Å"Long as I can spell G-o-d I got somebody along† She believes she is never alone or hopeless as long as she has God in her life, writing to God gives her hope, this hope is what helps her overcome the negative aspects of her Fatalistic path that seemed as though her life would be controlled by abusive males that would drive her to murder her husband just like Tess did. On the other hand Tess’ Fate is once again predetermined by Hardy in chapter 41 when she stumbles upon dying pheasents and puts them out of their misery by bringing their inevitable deaths to an end prematurely†¦ â€Å"Poor darlings-to suppose myself the most miserable being on earth in the sight o’ such misery as yours! † she exclaimed, her tears running down as she killed the birds tenderly. † This Fatalistic event represents Tess’ destiny as she to will die due to her neck breaking as she will later be hung, Hardy uses this sense of foreboding once again signifying the belief that her character is her Fate, she is unable to change this, nothing she does will alter it. Similarly but with a contrasting outcome, in Colour Purple Fate re-emerges as killin Mr†¦ begins to dawn on Celies mind. â€Å"How I’m gon keep from killing him†¦ Naw I think I feel better if I kill him, I say I feels sickish. Numb, now. † Mr†¦ has abused Celie to the extent that she contemplates killing him, at this stage of the book readers are likely to speculate whether Fate has chosen this path for Tess, is this her destiny? Will she have to emulate Tess’ action to end her misfortunes? Or will she be able to alter her Fate through her hope in God and rational actions? Although she doesn’t go on to murder Mr†¦ , through God and her companion Celie she finds the courage to speak up against Mr†¦ and leave him, ultimately changing her Fate which is something Tess was unable to do†¦ â€Å"You a low down dog is what’s wrong. It’s time to leave you and enter into the creation. And your dead body just the welcome mat I need. † Here Walker shows her strength and courage obtained through her hope in God. The authors use of foreboding throughout the novel can be seen as a representative of fate, Hardy believed that what happened to us was a product of our personality, class, status and the way in which we view life therefore Tess’ pride and her concern for Angels reputation after he leaves her prevents her from seeking help at an early stage of her troubles can be seen as her own actions but in Hardy’s view our own actions were down to fate , she ends up confiding in Alec which leads to disaster. From this we can question whether Tess’ actions lead to her downfall or was it Fate? This is demonstrated at the beginning of the final paragraph, hardy writes†¦ † ‘Justice’ was done, the president of immortals had ended his sport with Tess. † Hardy is telling us Fate has finished playing with its victim, Tess. He may have done this to further draw attention to his beliefs that we are subject to a immoral force beyond our control that we are forced to endure and that religion does not have bearing on any events in our life. This is a viewpoint that was developed by critic Irving Howe who too believed Tess’ fate had already been predetermined, Proposing this is why Hardy named the final phase of the novel ‘fulfilment’. Furthermore, another way Hardy depicts Tess as a victim of Fate is through the language he uses, particularly in the last phase of the novel as he named it ‘fulfilment’ thus this is a play on words as we are left to question what has been fulfilled. It is possible to say Hardy believed Fate had been fulfilled it had played it’s role in bringing Tess to her tragic downfall. Walker presents Celie as a victim of Fate like Hardy does Tess, however Walker stresses the point that we are able to change our Fate and destiny, this is significant as the colour purple which is the colour of the purple flowers represent spirituality & hope. She is almost trying to convey the message that, Fate can be overcome as long as hope is present, where as Hardy purposely doesn’t give Tess any chance of overcoming her Fate, he deliberately does this to assert his negative view on religion, Walker gives her character hope through God, this is what enables Celie to overcome her so called ‘Fate’ or ‘Destiny’ whilst Hardy’s pessimistic belief of religion deters him from doing this. Through his novels Hardy repeatedly articulated that chance and coincidence that bring about disaster are ultimately Fate, thus he empowers his belief through Tess that characters are subject to forces beyond their control. This is similar to another of his novels, ‘The Return of the Native. ‘ Throughout The Return of the Native bad things happen to good people, this is a depiction of his atheist perception that God does not exist and if there is a God it is lacking in morals, because good people, such as Tess are the victims of bad events and tragedy in life due to Fate. Like Hardy himself said†¦ ‘Once a victim, always a victim of fate. ‘

Bee Colony Algorithm For Rectangle Packing Problems Design Essay

Packing job is considered as an NP-hard job. It is an optimisation job of happening an optimum agreement of a set of points in a larger container with the aim of minimising the spread on the packing country or maximising the container use. This sort of job occurs in different industries and is important in mechanical design and industry, transit and in the development of a good layout design of an endeavor [ 9 ] . This job has been studied and different algorithms have been applied to come up with an optimum wadding agreement. Some optimisation algorithms that were used in work outing were familial algorithm and atom drove algorithm. Furthermore, another optimisation and swarm-based algorithm called the Artificial Bee Colony ( ABC ) algorithm is presented in this paper. It is an algorithm that is based on the scrounging behavior of bees. In this survey, the research worker will utilize the Artificial Bee Colony Algorithm in happening an optimum agreement of jammed rectangles. Packing jobs consider a set of points and a bin that will keep the points which aim to pack points every bit dumbly as possible with really optimum to no spreads. Packing jobs are helpful and widely used in several Fieldss such as in fabrication and in state of affairss like make fulling up containers, lading burden, ship edifice, building and ornament layout and so on [ .. ] . Packing jobs are classified depending on the job ‘s application and aim. Some of the most of import jobs such as cutting stock, backpack and bin packing [ 4 ] are defined below. The cutting stock job is about cutting various-sized pieces out on a given stock sheets. The job can either be a trim-loss job or an mixture job. Trim-loss Problem Trim-loss job is the allotment onto stock sheets of pieces of different sizes demanded by the clients with the purpose of minimising the cost of waste. Assortment Problem The mixture job is concerned in finding the size of the pieces or points to be kept in stock of sheets such that the best choice of points is used so waste is minimized. Knapsack Problem The backpack job describes the procedure of packing the most valuable points into a fixed-sized storage such as a backpack. The job consists of points with matching weights and values and a backpack of limited capacity. The aim of the backpack job is to find which points that maximize the value should be in the backpack given that the entire weight of the points is at most of the weight of the backpack. Taken from [ 12 ] Figure.1: Illustration on the backpack job Bin Packing Bin wadding job has a aggregation of points of different sizes and a figure of bins holding the same horizontal and perpendicular dimensions. There are different sorts of bin packing such as 2D wadding, 3D wadding, additive wadding, battalion by weight and more [ 14 ] . The aim of the job is to merely pack the points into the bins minimising the figure of bins used. Taken from [ 13 ] Figure.2: Bin wadding of different forms Loading Problems Loading jobs deal with rectangular boxes that are to be packed into a rectangular palette. These jobs can be classified into maker ‘s and distributer ‘s burden jobs [ 4 ] . Manufacturer ‘s and distributer ‘s burden jobs are chiefly concerned with the wadding of indistinguishable and non-identical rectangular pieces severally. The aim of lading jobs is to happen an optimum wadding form such that the figure of boxes to be placed in a certain palette or container is maximized. Taken from [ 15 ] Figure.3: Illustration on palette burden jobs for indistinguishable boxes Other Discrepancies of Packing Problems There are several sorts of packing jobs. The followers are some packing jobs that deal in â€Å" happening the maximal figure of a certain form that can be packed into a larger, possibly different form † [ 3 ] . Sphere in Cuboid – a sphere wadding job that involves in happening an optimum agreement of given a set of spherical objects with diameter vitamin D be packed into a cuboid with a size of a ten B x degree Celsius Packing Circles – are some circle packing jobs that attempt to pack a set of indistinguishable circles into a circle or another form Taken from [ 5 ] & A ; [ 6 ] Figure.4: ( a ) Circles in circle, ( B ) Circles in square ( degree Celsius ) Circles in equilateral trigon and ( vitamin D ) Circles in regular hexagon Packing Squares – shows a set of indistinguishable squares packed inside a form such as the square and circle Taken from [ 5 ] & A ; [ 6 ] Figure.5: ( a ) Squares in square and ( B ) Squares in circle Rectangle Packing Problems Rectangle Packing Problem Definition Rectangle wadding job is an optimisation job of apportioning a set of rectangle points into a larger rectangle, the container with the aim of minimising the packing country or the country wasted [ 8 ] . The set of rectangle points has different dimensions of width tungsten and tallness H and the entire country of the points should non transcend the country of the container width W and height H. The arrangement of the points is described by the undermentioned set of restraints [ 8 ] [ 10 ] [ 11 ] . No imbrication of rectangle points. No points must be wider or taller than the size of the container. Edges of the points must be parallel to the container ‘s border Taken from [ 7 ] Figure.6: Illustration of a authoritative rectangle wadding job process Taken from [ 1 ] Figure.7: A sample wadding of 9 rectangular points – 90o rotary motion allowed Taken from [ 1 ] Figure.8: A sample packing – fixed orientation, no rotary motion allowed Other Rectangle Packing Problems Packing Into An Open-ended Rectangle The job is described as arrangement, without overlapping, a set of rectangle points of different sizes in an open-ended rectangular container of width W. A rotary motion of 90A ° is allowed every bit long as no points overlap. All the rectangle points should be pack in manner that the entire length L of infinite occupied is minimized [ 1 ] . Taken from [ 1 ] Figure.9: A possible agreement of eight points Taken from [ 1 ] Figure.10: Packing into an open-ended rectangles with three different breadths. Packing Into Rectangles of Fixed Size The thought behind this job is similar to usual bin packing jobs. It consists of rectangle points of different horizontal and perpendicular dimensions and a set of rectangular sheets of fixed length and breadth. The aim is to â€Å" happen an agreement of the pieces that minimizes the figure of sheets needed † [ 1 ] . Taken from [ 1 ] Figure.11: Packing into fixed sized rectangles Drove Intelligence Swarm intelligence is defined as â€Å" any effort to plan algorithms or distributed problem-solving devices inspired by the corporate behavior of societal insect settlements and other carnal societies † [ 19 ] . What makes drove based algorithms an interesting mechanism for work outing jobs particularly NP-complete jobs is the two cardinal constructs within, self-organisation and division of labor. Some illustrations of swarm-inspired algorithms and surveies are Particle Swarm Optimization ( PSO ) , ant settlement, bee settlement, flock of birds and more [ 19 ] . The Artificial Bee Colony Algorithm The Artificial Bee Colony ( ABC ) algorithm is a nature-inspired optimisation algorithm defined by Dervis Karaboga in 2005 [ 2 ] . Based on the scrounging behavior of bees, the purpose of the algorithm is to happen nutrient beginnings with high nectar sums and finally take the 1 with the highest sum. In the ABC algorithm, bees are grouped into employed bees, looker-on bees and lookout bees. The employed bees are the 1 that exploit and keep the information of a peculiar nutrient beginning. The information on a specific nutrient beginning is so shared by each employed bees to the looker-on bees through a shake dance. Then, nutrient choice is done by the looker-on bees. These bees determine the quality of the nutrient beginnings and acquire to take the best nutrient beginning. When a nutrient beginning of an employed bee has been abandoned, this bee becomes a lookout bee. Scout bees are responsible for researching and seeking possible nutrient beginnings around the country. The Waggle Dance Bees need to pass on with other bees in order for them to happen and garner nutrient indispensable for the endurance of their settlement. One of the most interesting and challenging mechanisms of discoursing around the carnal land peculiarly Apis melliferas is dancing. Information on a certain nutrient beginning off from their hive is passed on to other bees through a shake dance. A shake dance is performed by a lookout bee informing his hive mates the exact way and distance to the nutrient beginning. During the shake dance, the bee performs an eight-figure form dance where it foremost walks in a consecutive line while waggling his tail back and Forth. Then looping is done in jumping waies and travels the consecutive line over and over once more capable to the way and the distance being relayed. Walking in the consecutive line indicates the way and figure of shakes refers to the distance of the nutrient beginning [ 16 ] [ 17 ] . Taken from [ 16 ] Figure.12: The shake dance The Algorithm The chief stairss of the ABC algorithm from [ 19 ] consisting of the employed bees, the looker-on bees and the lookout bees is given below. Figure.13: Main stairss of ABC Pseudocode of ABC The elaborate pseudocode of the ABC algorithm shown in [ 20 ] is given below: Initialize the population of solutions Xi Measure the population cycle=1 Repeat Produce new solutions ( nutrient beginning places ) Vi in the vicinity of Xi for the employed bees. Apply Greedy Selection Calculate the chance values Pi for the solutions Xi by agencies of their fittingness values utilizing the equation Normalize Pi values into [ 0,1 ] Produce the new solutions ( new places ) Vi for the looker-ons from the solutions Xi, Apply Greedy Selection Process for the looker-ons between Xi and Vi Determine abandoned Solutions, and replace it with new randomly produced solutions Xi for the lookout Memorize the best nutrient beginning place achieved so far rhythm = cycle+1 UNTIL ( rhythm = Maximum Cycle Number ) Initially, random executable solutions ( nutrient beginnings ) are generated and evaluated. Then, the employed bees will seek for new solutions in the vicinity out of the current solutions and the greedy choice is applied. The choice of much fitter solutions is done by the looker-on bees and is dependent on the fittingness value. The nutrient beginnings that do non better after a series of loop are abandoned and the bee associated to it eventually becomes a lookout. The lookout will seek for a new nutrient beginning once more. The whole procedure continues until the expiration standard is satisfied. Neighbourhood Search Neighbourhood searching is the procedure of bring forthing better solutions from the current executable solutions. A new solution is generated utilizing the equation below: ( 1 ) where XA ­ij is the value of cell in solution XA ­i ( current solution ) which is indiscriminately picked, XA ­kj is the value of cell J in XA ­k, a random solution non equal to XA ­i, O is a random value in the scope of [ 0, 1 ] . Greedy Selection The greedy choice is responsible of doing and taking the optimum solution at each phase of the procedure. Fitness Function A fittingness map determines the quality of a nutrient beginning ( solution ) . The higher the fitness value of the equation below, the better the solution is. ( 2 ) where is the cost map Probability Function The chance map determines the chance that a peculiar nutrient beginning will be preferred by looker-on bees. The chance value is calculated utilizing the expression below: ( 3 ) where I is the current nutrient beginning and Sn is the entire figure of nutrient beginnings. Literature Review In the paper â€Å" An Improved Genetic Algorithm for the Packing of Rectangles † by Ming Le Stefan Jakobs [ 22 ] in his paper entitled â€Å" On familial algorithms for the wadding of polygons † implemented a intercrossed attack to familial algorithm. Jakobs used the bottom-left-condition to cut down the figure of possible wadding forms. The initial population is composed of width-sorted sequence of agreements based on the bottom-left regulation. A rectangular piece is moved get downing from the upper right corner of the country and moving every bit far as to the bottom so allotment is done every bit far as to the left corner of the bounding rectangle. This construct of a intercrossed familial algorithm was besides used in wadding of polygons job. Chen Zhao, et al [ 23 ] introduced the construct of Discrete Particle Swarm Optimization ( DPSO ) algorithm. In this method, a. For a elaborate treatment on the said method, see [ 23 ] . Statement of the Problem Packing jobs such as rectangle packing belongs to the category of NP-hard jobs since there is no easy manner to find the optimum solution for every instance. Finding the best manner of suiting a figure of rectangles into a larger rectangle is a clip devouring repeating undertaking and involves a really big solution infinite. The ABC algorithm, a new swarm-based methodological analysis, has been proven to be an efficient attack that solves optimisation jobs in assorted countries. Some research surveies besides show that ABC outperforms other optimisation techniques such as familial algorithm. In this survey, the ABC algorithm will be implemented to work out rectangle packing jobs. Therefore, this paper will prove the efficiency of the ABC algorithm in happening the best possible agreement of packing rectangles.

Know More About Consonant Sounds and Letters in English

Know More About Consonant Sounds and Letters in English A consonant is a  speech sound thats not a vowel. The  sound of a consonant is produced by a partial or complete obstruction of the airstream by a constriction of the speech  organs. In writing, a consonant is any  letter of the alphabet except  A, E, I, O, U, and sometimes  Y. There are 24 consonant sounds in English, some voiced (made by a vibration of the vocal cords) and some voiceless (no vibration). Consonants Versus Vowels   When spoken vowels have no obstruction in the mouth, as opposed to consonants, which do. In his book Letter Perfect, the author David Sacks described the difference between speaking consonants and vowels this way: Whereas vowels are pronounced from the vocal cords with  minimal  shaping of expelled breath, consonant sounds are created through obstruction or  channeling  of the breath by the lips, teeth, tongue, throat, or nasal passage.... Some consonants, like B, involve the vocal cords; others dont. Some, like R or W, flow the breath in a way that steers them relatively close to being vowels. When consonants and vowels are put together, they form syllables, which are the basic units of pronunciation. Syllables, in turn, are the foundation of words in English grammar. Phonetically, however, consonants are much more variable. Consonant Blends and Digraphs When two or more consonant sounds are pronounced in succession without an intervening vowel (as in the words dream and bursts), the group is called a consonant blend or consonant cluster. In a consonant blend, the sound of each individual letter can be heard. By contrast, in a consonant digraph,  two successive letters represent a single sound. Common digraphs include G and H, which together mimic the sound of F (as in the word enough), and the letters P and H, which also sound like an F (as in phone). Silent Consonants In a number of cases in English, consonant letters can be silent, such as the letter B  following M (as in the word dumb), the letter  K  before  N  (know), and  the letters B and P before T (debt and receipt).  When a double consonant appears in a word,  usually only one of the two consonants is sounded (as in ball or summer). Stop Consonants Consonants can also serve as a means of bracketing a vowel, stopping their sound.  These are called  stop consonants  because the air in the vocal tract is completely stopped at some point, usually by the tongue, lips, or teeth.  Then to make the consonant sound, the air is suddenly released. The letters B, D, and G are the most frequently used stops, though P, T, and K also can serve the same function. Words that contain stop consonants include bib and kit. Stop consonants are also called plosives, as their sounds are small explosions of air in the mouth. Consonance Broadly,  consonance  is the repetition of consonant  sounds; more specifically,  consonance  is the repetition of the consonant sounds of accented syllables  or important words.  Consonance is frequently used in poetry, song lyrics, and prose when the writer wants to create a sense of rhythm. One well-known example of this literary device is the tongue twister, She sells seashells by the seashore. Using A and An   In general, words that begin with vowels should be introduced by the indefinite article an, while words that start with consonants are set off with an a instead. However, when the consonants at the beginning of the word produce a vowel sound, you would use the article an instead (an honor, a house).

Assignment #3 PKG 381 Example | Topics and Well Written Essays - 250 words

#3 PKG 381 - Assignment Example Comparably, the creation teachings in Christianity clearly narrate that God created humans so they may have control over other animals. This implies that man should dominate and control other animals, as well as plans and the nonhuman things. The Garden of Eden was given to a man as a habitat where man would live. This signifies the close relationship man and other nonhuman had from the time of creation. However, this misused to man by God has been misused extensively. For example, a person today may kill an animal or clear a forest unjustifiably and claim it is biblically allowed (Clowney & Mosto, 2009).   The Islamic teachings about creation also support the arguments presented by Christianity that man was commissioned to steward other animals. However, Islam goes ahead to explain that every person will account for their actions in relation to the environment. This is the point of dissimilarity between the two religions as far as this issue is concerned. Islam agrees that man has the stewardship role, but the actions must be judged in the end by the creator (Clowney & Mosto,

Cryptography and Computer Security Essay Example | Topics and Well Written Essays - 2250 words

Cryptography and Computer Security - Essay Example virus from which the computer needed protection. Issues continued to arise but the most serious problem came with the introduction of internet. Internet gave birth to many problems because the internet gave rise to many virtual access points. Access points are an entrance to every sort of information and along with the information that enters virus and other malwares can easily enter. This opened a gateway to many virus and unwanted material into the computer. In order to protect the computer from such threats many techniques and methods were adopted and up till now new techniques and soft wares are being developed to protect the computer. One such method of protecting data is cryptography. It was used to convert understandable data into data that cannot be understood. In the earlier years cryptography was used to protect and secure information and messages between important personnel but gradually cryptography began to be used for the protection and safety of all sorts of communicat ion and safe computing. CRYPTOGRAPGY Cryptography has generally been used widely and there are some keys that are written for public and the major reason is to protect the data that is being transferred that is why it usually remains a secret or a matter of confidentiality between the receiver and the sender. It is a matter of great concern for the government and especially the law enforcing agencies when the data is encrypted as they need to be better equipped with programs and software so as to be counter the encrypted data and be able to read it. This is the sole reason that previously there was such a hue and cry with relations to the matter of privacy. It was discovered that there was no mail or communication that was hidden from them. They had super software and super computers to help them decode the algorithms and be able to decipher it. Earlier in 2009 there a series of very serious attacks on various organizations like Yahoo, Google, Morgan Stanley, Juniper Networks, Syman tec, Dow Chemical and the Adobe Systems. It was an attempt to get hold and manipulate the SCM of these organizations. The SCMs were wide open for access and the organizations never thought of protecting them as they felt that it was safe. The SCMs are quite an important part of any programs as they help when the person is looking to restructure the programs or rewrite them for any changes that are required. The main reason for the attack was to modify the SCM and then re modify the programs to their own motives. This attack showed how vulnerable the SCMs were. The result of this attack was to encrypt the SCM so that even if anyone got hold of them they would not be able to modify it. The encryption codified the programming and thus it was useless until the person was an expert in the algorithms. The attack basically modified the file path and turned normal usable software into malwares. It was at first discovered by the Google blog and then as a result they put forward an ultimatum that this originated in china and if it is not taken care of Google would close its franchise in China. There were further algorithms that were released from time to time just to exploit the loopholes that existed in various very commonly used software and this was done by random programmers. Encryption helps prevent such attacks (Stallings, 2011). With the advent of
