Introduction Intrusion Detection Systems (IDS) are security tools that, like other measures such as antivirus software, firewalls and access control schemes, are intended to strengthen the security Of information and communication systems. Although, as shown in Kabuki and Giordano (2005) and Sobs (2006), several IDS approaches have been proposed in the specialized literature since the origins of this technology, two highly relevant works in this direction are Dinning (1987) and Stanford-Chem. et al. (1998). Noteworthy work has been carried out by CDC (Common Intrusion Detection Framework), a working group created by DARPA in 1 998 mainly oriented towards coordinating and defining a common framework in the IDS field. Integrated thin IETF in 2000, and having adopted the new acronym IDS (Intrusion Detection Working Group), the group defined a general IDS architecture based on the consideration of four types of functional modules (Fig. L): E blocks C Event-boxes): This kind of block is composed of sensor elements that monitor the target system, thus acquiring information events to be analyzed by other blocks. D blocks (Database-boxes): These are elements intended to store information from E blocks for subsequent processing by A and R boxes. A blocks (Analysis-boxes): Processing modules for analyzing events and detecting potential hostile behavior, so that some kind of alarm will be generated if necessary. * Corresponding author.

R blocks Correspond-boxes): The main function of this type of block is the execution, if any intrusion occurs, of a response to thwart the detected menace. Other key contributions in the IDS field concern the definition of protocols for data exchange between components (e. G. IDS, Intrusion Detection exchange Protocol, RFC 4767), and the format considered for this (e. G. TIMED, Intrusion Detection MEssage Format, RFC 4765). Depending on the information source considered (E boxes in Fig. ), an IDS may be either host or network-based. A hostesses IDS analyzes events such as process identifiers and system calls, mainly related to SO information. On the other hand, a network-based IDS analyzes network related events: traffic volume, IP addresses, service ports, protocol usage, etc. This paper focuses on the latter type of IDS. Depending on the type of analysis carried out (A blocks in Fig. ), intrusion detection systems are classified as either signature-based or anomaly-based. Signature-based schemes (also denoted as misuse-based) seek defined patterns, or signatures, within the analyzed data. For this purpose, a signature database corresponding to known attacks is specified a priori. On the other hand, anomaly-based detectors attempt to estimate the normal behavior of the system to be protected, and generate an anomaly alarm whenever the deviation between a given observation at an instant and the normal behavior exceeds a predefined threshold. Another possibility is to model the abnormal behavior of the system and to raise an alarm when the difference between the observed behavior and the expected one falls below a given limit. Signature and anomaly-based systems are similar in terms f conceptual operation and composition. The main differences between these methodologies are inherent in the concepts of attack and anomaly. An attack can be defined as a sequence of operations that puts the security of a system at risk. An anomaly is just an event that is suspicious from the perspective of security. Based on this distinction, the main advantages and disadvantages of each IDS type can be pointed out. Signature-based schemes provide very good detection results for specified, well-known attacks. However, they are not capable of detecting new, unfamiliar intrusions, even if they are built as minimum Arians of already known attacks. On the contrary, the main benefit of anomaly-based detection techniques is their potential to detect previously unseen intrusion events. However, and despite the likely inaccuracy 2. A-NDIS techniques Although different A-NDIS approaches exist (Est. postoperative et al. , 2004), in general terms all of them consist of the following basic modules or stages (Fig. 2): Parameterization: In this stage, the observed instances of the target system are represented in a pre-established form. Training stage: The normal (or abnormal) behavior of the yester is characterized and a corresponding model is built. This can be done in very different ways, automatically or manually, depending on the type of A-NDIS considered (see classification below). Detection stage: Once the model for the system is available, it is compared with the (parameterized) observed traffic. If the deviation found exceeds (or is below, in the case of abnormality models) a given threshold an alarm will be triggered (Est. ;fez-Topiary et al. , 2004). According to the type of processing related to the behavioral model of the target system, anomaly Parameterization n formal signature specifications, the ra te of false positives (or UP, events erroneously classified as attacks; see Section 2) in anomaly-based systems is usually higher than in signatures ones. Given the promising capabilities of anomaly-based network intrusion detection systems (A-NDIS), this approach is currently a principal focus of research and development in the field of intrusion detection. Various systems with A-NDIS capabilities are becoming available, and many new schemes are being explored. However, the subject is far from mature and key issues remain to be solved before wide scale deployment of A-NDIS littorals can be practicable. Focusing, thus, on A-NDIS technologies, the rest of this paper is organized as follows: Section 2 presents the various algorithms proposed for anomaly detection. Then, existing A-NDIS platforms, either currently available or under development, and which include anomaly detection functionalities, are presented in Section 3. This constitutes a valuable contribution of the present paper in comparison with other published work. The fourth section discusses open issues and challenges in this field, with special emphasis on A-NDIS assessment. Finally, Section 5 summarizes the main mints of the paper. Monitored environment Training Model Detection Intrusion report Fig. 2 Generic A-NDIS functional architecture. 0 detection techniques can be classified into three main categories (Lacerative et al. , 2005) (see Fig. 3): statistically, knowledge- based, and machine learning-based. In the statistical-based case, the behavior of the system is represented from a random viewpoint. On the other hand, knowledge-based A-NDIS technique uses try to capture the claimed behavior from available system data (protocol specifications, network traffic instances, etc. ). Finally, aching learning A-NDIS schemes are based on the establishment of an explicit or implicit model that allows the patterns analyzed to be categorized. Two key aspects concern the evaluation, and thus the comparison, of the performance of alternative intrusion detection approaches: these are the efficiency of the detection process, and the cost involved in the operation. Without underestimating the importance of the cost, at this point the efficiency aspect must be emphasized. Four situations exist in this context, corresponding to the relation between the result of the detection for an analyzed event (normal vs.. Intrusion) and its actual nature (innocuous vs.. malicious). These situations are: false positive (UP), if the analyzed event is innocuous (or clean) from the perspective of security, but it is classified as malicious; true positive (HTTP), if the analyzed event is correctly classified as intrusion/malicious; false negative (FAN), if the analyzed event is malicious but it is classified A.

As normal/innocuous; and true negative (TN), if the analyzed event is correctly classified as normal/innocuous. It is clear that low UP and FAN rates, together with high HTTP and TN rates, will result in good efficiency values. The fundamentals for statistical, knowledge and machine learning-based A-NDIS, as well as the principal subtypes of each, are described below. The main features of all are unmarried in Table 1 . Above and beyond other possibilities, the question of efficiency should be a prime consideration in selecting and implementing A- NDIS methodologies. 2. 1. Statistical-based A-NDIS techniques In statistical-based techniques, the network traffic activity is captured and a profile representing its stochastic behavior is created. This profile is based on metrics such as the traffic rate, the number of packets for each protocol, the rate of connections, the number of different IP addresses, etc. Two datasets of network traffic are considered during the anomaly detection process: one responds to the currently observed profile over time, and the other is for the previously trained statistical profile. As the network events occur, the current profile is determined and an anomaly score estimated by comparison Of the two behaviors. The score normally indicates the degree of irregularity for a specific event, such that the intrusion detection system will flag the occurrence of an anomaly when the score surpasses a certain threshold. The earliest statistical approaches, both network oriented and host oriented IDS, corresponded to inebriate models, which modeled the parameters as independent Gaussian madman variables (Dinning and Neumann, 1985), thus defining an acceptable range of values for every variable. Later, multivariate models that consider the correlations between two or more metrics were proposed (Ye et al. , 2002). These are useful because experimental data have shown that a better level of discrimination can be obtained from combinations of related measures rather than individually. Other studies have considered time series models (Detecting Hackers), which use an interval timer, together with an event counter or resource measure, and take into account the order and the enter-arrival times of the observations as well as their values. Thus, an observed traffic instance will be labeled as abnormal if its probability of occurrence is too low at a given time. Apart from their inherent features for use as unemployable techniques, statistical A-NDIS approaches have a number of virtues. Firstly, they do not require prior knowledge about the normal activity of the target system; instead, they have the ability to learn the expected behavior of the system from observations. Secondly, statistical methods can provide accurate notification of malicious activities occurring over long roods of time. However, some drawbacks should also be pointed out. First, this kind of A-NDIS is susceptible to be trained by an attacker in such a way that the network traffic generated during the attack is considered as normal. Second, setting the values of the different parameters/metrics is a difficult task, especially because the balance between false positives and false negatives is affected. Moreover, a statistical distribution per variable is assumed, but not all behaviors can be 21 Table 1 Fundamentals of the A-NDIS techniques Technique: basics A) Statistical-based: autistic behavior B) Knowledge-based: availability of prior knowledge/data C) Mach nine learning-based: categorization of patterns Pros Cons Us Betsey Prior knowledge about normal activity not required.

The Major Alliances of World War I

The Major Alliances of World War I By 1914, Europes six major powers were split into two alliances that would form the warring sides in World War I. Britain, France, and Russia formed the Triple Entente, while Germany, Austria-Hungary, and Italy joined in the Triple Alliance. These alliances werent the sole cause of World War I, as some historians have contended, but they did play an important role in hastening Europes rush to conflict. The Central Powers Following a series of military victories from 1862 to 1871, Prussian Chancellor Otto von Bismarck formed a German state out of several small principalities. After unification, Bismarck feared that neighboring nations, particularly France and Austria-Hungary, might act to destroy Germany. Bismarck wanted a careful series of alliances and foreign policy decisions that would stabilize the balance of power in Europe. Without them, he believed, another continental war was inevitable. The Dual Alliance Bismarck knew an alliance with France wasn’t possible because of lingering French anger over Alsace-Lorraine, a province Germany had seized in 1871 after defeating France in the Franco-Prussian War. Britain, meanwhile, was pursuing a policy of disengagement and reluctant to form any European alliances. Bismarck turned to Austria-Hungary and Russia. In 1873, the Three Emperors League was created, pledging mutual wartime support among Germany, Austria-Hungary, and Russia. Russia withdrew in 1878, and Germany and Austria-Hungary formed the Dual Alliance in 1879. The Dual Alliance promised that the parties would aid each other if Russia attacked them or if Russia assisted another power at war with either nation. The Triple Alliance In 1882, Germany and Austria-Hungary strengthened their bond by forming the Triple Alliance with Italy. All three nations pledged support should any of them be attacked by France. If any member found itself at war with two or more nations at once, the alliance would come to their aid. Italy, the weakest of the three, insisted on a final clause, voiding the deal if the Triple Alliance members were the aggressor. Shortly after, Italy signed a deal with France, pledging support if Germany attacked them. Russian Reinsurance Bismarck was keen to avoid fighting a war on two fronts, which meant making some form of agreement with either France or Russia. Given the sour relations with France, Bismarck signed what he called a reinsurance treaty with Russia, stating that both nations would remain neutral if one was involved in a war with a third party. If that war was with France, Russia had no obligation to aid Germany. However, this treaty lasted only until 1890, when it was allowed to lapse by the government that replaced Bismarck. The Russians had wanted to keep it. This is usually seen as a major error by Bismarcks successors. After Bismarck Once Bismarck was voted out of power, his carefully crafted foreign policy began to crumble. Eager to expand his nations empire, Germanys Kaiser Wilhelm II pursued an aggressive policy of militarization. Alarmed by Germanys naval buildup, Britain, Russia, and France strengthened their own ties. Meanwhile, Germanys new elected leaders proved incompetent at maintaining Bismarcks alliances, and the nation soon found itself surrounded by hostile powers. Russia entered into an agreement with France in 1892, spelled out in the Franco-Russian Military Convention. The terms were loose but tied both nations to supporting each other should they be involved in a war. It was designed to counter the Triple Alliance. Much of the diplomacy Bismarck had considered critical to Germanys survival had been undone in a few years, and the nation once again faced threats on two fronts. The Triple Entente Concerned about the threat rival powers posed to the colonies, Great Britain began searching for alliances of its own. Although Britain had not supported France in the Franco-Prussian War, the two nations pledged military support for one another in the Entente Cordiale of 1904. Three years later, Britain signed a similar agreement with Russia. In 1912, the Anglo-French Naval Convention tied Britain and France even more closely militarily. When Austrias Archduke Franz Ferdinand and his wife were assassinated in 1914, the great powers of Europe reacted in a way that led to full-scale war within weeks. The Triple Entente fought the Triple Alliance, although Italy soon switched sides. The war that all parties thought would be finished by Christmas 1914, instead dragged on for four long years, eventually bringing the United States into the conflict. By the time the Treaty of Versailles was signed in 1919, officially ending the Great War, more than 11 million soldiers and 7 million civilians were dead.

Explain how solar energy can be used to produce electricity Essay

Explain how solar energy can be used to produce electricity - Essay Example The amount of energy emitted in one second is more than the world has used since time began. All energy comes from within the sun. Like other stars present in the cosmos, the sun is also a star made up mostly of hydrogen and helium gas. The cultivation of energy inside the sun is done through a process called nuclear fusion. However, only a small amount of energy reaches the earth but that is huge enough to supply all our energy needs. The energy radiated by the sun reaches the earth in just eight minutes at a speed of 186,000 miles per second, which is the speed of light. Photovoltaic Electricity as the name suggests is a combination of two words: photo meaning light and volt, a unit for the measurement of electricity. In short, it is often called PV cells or solar cells. The most common devices, which use PV cells include solar-powered toys, calculators, and roadside telephone call boxes – all use solar cells to convert sunlight into electricity. Scientific investigation of photovoltaic effect started in 1839 and the effect was first observed in a solid material (Selenium) in 1877. Solar cells are made up of silicon, the second most common substance on earth. Solar cells can be applied to produce energy to anything that is powered by batteries or electrical power in general. Electricity is generated when sunlight hits on the solar cell plates, which cause the electrons to get activated. However, the generation of electricity takes place mutely and at once. A PV or solar cell consists of two or more layers of semi conducting material, silicon, which is used most commonly in PV cells. When the silicon layer is exposed to the sunlight, a photo-voltage or potential difference between the layers is generated. This voltage is capable of driving a current through an external circuit, as direct current (DC). Since the electrical output from a single

Unemployment and its Effect on Consumer Spending Term Paper

Unemployment and its Effect on Consumer Spending - Term Paper Example Unemployment and its effect on Consumer Spending Unemployment has been a major issue that has been prevailing in every country’s economy since the global economic recession hit the world during the year 2007.This is calculated by the dividing the total number of unemployed population with that of the employed ones in the country. Unemployment within a country can bring upon many different negative issues within an economy and this could further deteriorate the country’s performance. Consumer spending is an issue that is considered to have an inverse relationship with unemployment. This relation can be graphically presented as follows: Consumer spending is the total aggregate demand of goods and services within an economy. Consumer spending, in simpler terms, can be referred to as the expenditure made by an individual. Consumer spending usually gets affected by different factors prevailing within an economy. There are many different factors that can vary the level of consumer spending. Unemployment has brought upon sev ere effects on consumer spending within the entire world. An increase in the level of unemployment was seen when the recession hit within the 2007, although this recession is considered to be the second recession within the same decade i.e. 2000 – 2010, it had severe negative effects. The reason that the 1st recession was less damaging was because during that period i.e. 2001-2002, people carried out their respective expenditure trends because they availed the mortgage facility. On the other hand, consumer spending was severely affected during the second recession period i.e. 2007.... Although the Bureau of Labor Statistics within the United States showed a reduction in the unemployment rate i.e. a fall of 0.4%, people still find it really difficult to find jobs within the country. According to many different commentators, the figures provided by the Bureau of Labor Statistics do not prove to be closer to reality. According to these commentators, an average unemployed worker approximately needs 33 weeks to find a job for himself. Such fall back and deteriorating facts contrast the figures provided by the Bureau of Labor Statistics and it is for this reason that many commentators have considered it to be bias (Jacob, 2011). The recent unemployment rate within the United States can be graphically shown as below (WSJ, 2012) This increase in the rate of unemployment has led to a reduction in the consumer spending level within the United States. Unemployment and consumer spending have contrasting issues i.e. they are inversely proportional. An increase in the level of unemployment would definitely reduce the level of consumer spending within an economy. Consumer spending is a necessary element that is required to stimulate an economy and it is for this reason, many governments try to put in proper monetary and fiscal policies that may increase consumer spending in order to reduce inflation and maintain other economic factors within a country. The United States consumer spending level has not been pleasing during the past few years. According to the US Commerce Department, the consumer spending has risen by just a minute 0.1%. This increase has been considered to be really low as opposed to the predictions made by the US Commerce department. The United States

William Blake Poems Essay Example for Free

William Blake Poems Essay Songs of Innocence and Songs of Experience appears to be very simplistic on first reading. Explain how the poems are in fact a much more complex exploration of Blakes beliefs and times. William Blake was born in London in 1757. He was home educated and was part of the upper working class as his father was a hosier. He was sent to a drawing school and was a dissenting Christian. His Christian beliefs are reflected in several of his poems. Blake became married in 1783 and married for love rather than money and status. To understand his poems fully we first need to understand what the titles of his two major sets of poetry mean. Innocence in the terms of Blakes poetry is a person who has very little experience and does not know about the bad things that happen in life-Quoted from the Dictionary. Immediately a link is made between the songs of Innocence and Songs of Experience. Experience on the other hand means (the process of getting) knowledge or skill which is obtained from doing, seeing or feeling things-Quoted from the Dictionary. These two themes are explored significantly within the poems. During Blakes time in London he saw many different movements and ideas develop such as a revolution in America where a group of British Colonies decided to rebel against Britain in their chance to gain independence. When the victory of this was won America and its allies of France and Spain went to war against Great Britain. Blake used this amongst other themes as the base for his poetry, and because of this he is associated with the Romantic poets even though he was not classed as a Romantic. Another main theme at the time was the use of seven year olds as chimney sweeps. Young boys were used because hard tar often got caught up in the chimney which a brush could not dislodge. To send a boy up was the easiest way to get rid of it and the flexible undeveloped body made it easy. They were often caught in the chimneys and many became cripples and got suit filled lungs. In London alone there were over 1000 sweeps. Blake uses this as one of the topics for both Songs of Experience and Inn ocence. In his two poems The Chimney Sweeper he utilises several literary techniques to create a successful poem. In The Chimney Sweeper (Innocence) Blake uses sorrowful imagery to create an atmosphere of anger and pain, my father sold me while yet my tongue shows just how young the boys were when they sold into the apprenticed with a master sweep. The repetition of, weep!, meant to be sweep which adds to the words meaning because it links the job of the child with his sorrow and also creates an atmosphere of rhythm of a brush going up and down within the chimney. On the other hand in The Chimney Sweeper (Experience) the boy is not introduced by his father but by a description of himself as a black thing amongst the snow which sounds as something discarded and dehumanises him. In this case snow is not used for peace and purity but for cold and harshness. The colour opposites of white snow and black dirty boy are another literacy technique of comparative representation by descriptive contrast. Weep is also used in this version but the words are described as being criedin notes of woe! This links directly to sadness and cruelty rather than being hidden inside the verse as is shown in Songs of Innocence. Religion is brought into this by the parents going to church to pray which also illustrates the normalness of their lives compared to their sons and highlights their hypocrisy. This is due to them being all good by going to Church and yet they are sending their son to work at such a young age and are almost bringing upon his fate of an unhappy life. In the second verse in the Innocence version the boys head curled like a lambs back which links to the symbolism of the lamb being the son of God which is one of the main themes in another poem from Songs of Innocence the Lamb. The Lamb is a prime example of innocence imagery because it is used in such a context as to promote the idea that the lamb symbolises not only pastoral imagery but Christ as the lamb of God. The boys hair is described as white to represent purity and innocence but then colour imagery is used to emphasise dark and light, good and bad. In The Chimney Sweeper (Experience) the boys appearance is described yet in a different way to that of the innocence poem, his health is described first as happy but this is talked about in the past tense. Blake is touching on the illnesses Chimney Sweepers got, such as cancer. His clothes are then described metaphorically as Clothes of death which when put into context of the work he was doing tells the reader that the clothes he is wearing to work symbolise his status and remind the reader that this job was very hazardous and also is describing the soot on his body. This again links into the poem The lamb where the clothes are described as Softest clothing woolly bright which has no indication of death by of life. This shows the difference between life and death as in most Chimney Sweepers lives death came upon them unnaturally quickly. Some children that were not put into the trade of chimney sweeping then they would instead be educated (if their parents possessed the money) and if not the children were sent to Charity schools. These were schools that were established by mainly religious organisations and were used to educate children until they could be put into a trade. These schools were often cruel institutions. Blake uses the subject of Charity Schools for one of his sets of poems entitled Holy Thursday. The title Holy Thursday comes from the British celebration of Jesus ascension. In the first line (of the Innocence version) it mentions the children who were in this school as having innocent faces clean showing immediately that Blake found them to be innocent. The second line has a Bible reference to Noahs ark; the children walking two two makes them sound more like animals and is also reminding the reader that just like Noahs animals they were the future of Blakes Britain. It also signifies that they were the future of the world as were the animals in Noahs ark. From his poems we can somewhat assume that Blake found Charity schools to be a money making scheme. This is proved by his view on the so called religious people who ran the schools. In the second line the masters are described as having wands as white as snow which shows them as having power because although white is generally used to show innocence in this case the word snow contradicts this as Blake often used snow to symbolise cold, dark and evil ambitions and scenarios. London is also mentioned in the first verse by the high dome of Pauls and the Thames water which in those days was very dirty, but was an integral part of London as were the children. Blake uses religious imagery within the innocence version quite a bit towards the end. A mighty wind[raised] to heaven, is used to create an idea based around the childrens voices as if they were crying so loud that heaven could hear them. The owners are described as wise guardians, which is ironic and patronising as Blake actually is meaning that they are horrible and cruel and have no knowledge what so ever. In the experience version of Holy Thursday Blake puts forwards different ideas. He starts off by talking about the fruitful children which are then reduced to misery. This symbolises them coming into the schools cheerful and full of happiness and then being shafted out woeful. The representation of children to money is also used by calling them rich. This has been used to remind the reader that Blake saw the owners of these schools as money hungry and the only reason they did it was for the money. In the second verse Blake talks of the feelings of the children as trembling [cries], the meaning of this is to show that the children were desperate as they were children poor?. Pastoral imagery is used in this version not to represent innocence to the destruction of innocence via experience Field are bleak and bare. This shows that after the schools the children had lost their innocence, stripped of it, and there was and is nothing they could do about it, It is eternal winter there shows the eternal evil within the schools. From this anger of London via the chimney sweeps and charity schools we find even more anger within Blakes poem A Poison Tree. This poem expresses Blakes anger and hatred for things in general. The last verse of this poem sums up what happened to the innocence of the children And into my garden stole-It had been stolen. A Poison Tree is another poem from Blakes Songs of Experience. It follows a different rhyming pattern compared to other poems written by Blake. It uses the rhyming patter a,a, b,b whereas other poems generally used a,b,a,b. This change in rhyme immediately hits the reader and also makes the poem more alive with passion due to the flow of the rhythm. The first lines holds a contradiction I was angry with my friend, it forces the reader to ask the question of why the person is angry with their friend, it insights them to read on. It talks of how the person in the poem tell his friend why he is angry with him and because of this [his] wrath did end. On the other hand when it comes to being ,angry with [his]..foe, he did not say anything and so the ,wrath did grow. The meaning of this first verse is to try and show that by keeping anger hidden within other things it does not diminish but grows. This links in to what Blake was doing. He did not openly express his views but concealed his anger within his poetry. The second verse talks of tears and smiles these two opposites show split personality. The meaning of the tears is the water that the Poison tree was given and the smiles are the sun. This contradiction makes the tree slowly grow ,both day and night. This idea of growth relates to children growing up but being fed with the wrong views which means that they can turn out evil. This view of the, finished product, is shown when the tree bore and apple. The apple signifies the apple in Genesis and the evil of the world was concealed in this apple. Maybe Blake is trying to say the God was wrong to conceal the evil within one thing and that from it more evil has occurred which is true. The last link to religion links into Blakes poem The Echoing Green from Songs of Innocence which shows a completely different view of the world. This poem also follows the same rhyming pattern of A Poison Tree which once again gives it more flow and rhythm. When read, the poem has a sort of Sing song feel to it which goes along with the happiness expressed within the poem. It talks of change from innocence to experience. In the second verse Blake talks about a monk Old John and then links him to experience with White hair. The white described in this verse is a pure white which shows that Blake is not totally against experience. There is alot of repetition in this poem with, bells, symbolising religious festivals such as Christmas which tells the reader a little about Blakes religious life. The repetition emphasis this and makes the reader take it in. Blake also links children with pastoral imagery, girls and boys were seen One the Echoing Green which is used as another way of expres sing that the children are innocent. This idea of pastoral imagery is also shown in two of Blakes most famous poems The Lamb and The Tyger. In these two poems Blake uses several imagery techniques. In The Lamb he puts forwards the idea of nature via Stream and Oer the mead. The idea of nature links into innocence and the fact that the countryside is un-poisoned as it has not been influence by the hammer, Chain and furnace mentioned in The Tyger which symbolises the industrial revolution which is William Blakes view on experience altering innocence. William Blake links the industrial revolution with the, forests of the night [and] hand or eye, which is imagery of humans and shadows. As William Blake was a devout Christian in his own way he includes God in his poem of The Lamb. In fact God is included in the name of his poem as Jesus was the lamb of God. Blake uses assonance to create subtle rhyming in which the reader can pick up over time. Softest clothing is an example of this. The subtle link adds to the effect of beauty that the Softest clothing creates. The use of this adds meaning to the poem because clothing is used to cover people and so William Blake might be trying to say that by covering your true self you are loosing the innocence of individuality. Another effect used in The Lamb is the fact that there is not much punctuation. This surprisingly creates a weird flowing nursery rhyme effect. On the other hand in The Tyger lots of somewhat harsh punctuation is used to create a pounding rhyme which inspires the reader to imagine the atmosphere of machinery. The reason for the mis-spelling of tiger is because Blake was self taught. This is a good example of differences in class at the time of William Blake. The poems from Songs of Innocence and Songs of Experience have more meaning than the reader might first imagine due to mainly the events that were surrounding their author William Blake at the time of their writing. By the harsh reality of London at that time Blake incorporates the Chimney sweeps, Charity schools, London in general and the industrial revolution into his poems. He does not openly state what each poem is about but within in writing we can pick up on ideas and themes that influenced him to write these poems. While reading these poems people pick up on the things happening at the time due to the detail in which they are described in poetry. These poems are not just poems, they are more like Blakes autobiography on his life through the form of media he liked best, poetry.

Constitutional Convention: Day by Day Occurrences :: Government Essays

Constitutional Convention: Day by Day Occurrences May 29, 1787 After these few short days of the convention here in Philadelphia, I realized that it would be important to keep personal records of this convention to assist in future discussion. This will also help me with remembering details of the events. Today the "Virginia Plan" was presented by that state's delegates. They proposed a series of many resolutions that seemed well thought out to me. The plan was written by James Madison but was given to us by Edmund Randolph who was a very effective speaker and clear orator. I enjoyed listening to the resolutions and the fresh new ideas I heard in the Virginia Plan. First, the Virginia Plan recommended a bicameral legislature with representation to be determined by the size of the population in each area.

This will also help me with remembering details of the events. Today the "Virginia Plan" was presented by that state's delegates. They proposed a series of many resolutions that seemed well thought out to me. The plan was written by James Madison but was given to us by Edmund Randolph who was a very effective speaker and clear orator. I enjoyed listening to the resolutions and the fresh new ideas I heard in the Virginia Plan. First, the Virginia Plan recommended a bicameral legislature with representation to be determined by the size of the population in each area. The lower body of this legislature would be elected by voters while the upper house would be elected by the members of the lower house.

League of Legends

The poem Funeral Blues, which was written by W H Aden, is a beautiful poem in which the poet conveys the meaning through rhythm and scarring scenes he paints of lost love and anguish. The poem is about the death of a loved one and the actions taken after in the lead up to the funeral, as can be told by the title. The first stanza is striking with the poet creating a silence In your head; the second describes the preparation in a solemn tone that seems to echo for me as the reader.In the third stanza you are shown the love and anguish In Its full light through the slow rhythm of he words with many comma's to add an aura of suspense and depression, male pronouns are used to describe the dead person whose body fills the coffin so the poet Is subtly making reference to his sexuality as though to make a point of his sadness, being gay himself. Finally the fourth stanza finishes the poem with words that suggest a lack of hope from someone who has given up In life. The main ideas that are e xpressed in the poem are centered on loss: they circle around death and how it affects the surrounding people when it takes a loved one.The main idea expressed by the poet is that without this person he is writing about his world is unable to go on. You see this in a beautiful scene in ‘Four weddings and a funeral,' when the poem is read out at the funeral of the readers partner. He talks slowly and as the camera pans out you see the whole audience is crying silently, silence being a key part of W H Addend's poem. Silence. His last stanza makes me as the reader feel like the world is caving in on me which links into the loss of hope and happiness and completely tears at the reader's heart.The mood silently creeps of the page and into the readers mind, illustrating the distress that flows through the lines as though it where a stream. It is dark and without light and as I have said before it was without hope. He focused on using language that could be understood by any age to s ymbolism that everyone could understand what he was feeling, that it was neither easy nor hard to relate. The poem Is about hopelessness against the force of our nature, of life and of death that the poet conveys through his slow rhythm and depressive mood.The Imagery used by W H Aden was an essential part of the effectiveness of the emotion behind the poem. He used It to paint pictures that affected the readers. With some very scaring pictures painted through auditory, and some beautiful, sad pictures painted through visual. These are used to make the audience react to the poem as though it where a recount of their own feelings. Prevent the dog from barking with a Juicy bone, Silence the pianos and with muffled drum† This quote is an example of auditory imagery.It creates a silent wind in the reader's ears and the world the poem creates becomes darker due to the idea of silence. Silence is one of the main horrors of death from the poem and it links directly to the sadness of love and life. Personally when I see this line I can hear the beat of a cuckoo clock cutting of mid call, the cord on a telephone, ripped from it's socket and as the silence becomes more, then suddenly the sound of the slow muffled drums of a parade, making its way towards me. This is an example of great description in my mind because it conveys the significant meaning of the poet's silence in a few words.Put crepe bows round the white necks of the public doves, Let the traffic policemen wear black cotton gloves. † Is an example of visual imagery by themselves the lines are beautiful and peaceful, but they add to the sorrow through their calm, delicate, beauty when combined with the rest of the poem. It is amazing how Aden has intertwined doves into his dark and sorrowful poem as they are a sign of love, peace, holiness and fertility, not death, sadness and the sin of homosexuality in many cultures. â€Å"The stars are not wanted now; put out every one, Pack up the moon and d ismantle the sun,Pour away the ocean and sweep up the wood; For nothing now can ever come to any good† This stanza is the most visual, I myself am able to see people covering the stars with black cloth, pulling down the sun, bit by bit, and clearing the land dry and barren. W H Addend's poem Funeral Blues shows the reader that death is a force stronger than life and love stronger than the both; he does this through the visual imagery he has created throughout the stanzas to create a sense of harsh peace and auditory imagery to chill the reader with the power of silence.

Problems with Education Essay

What is it that’s making our nation suffer from excelling in education? Not many would argue about the importance of excellence in education. Problems such as teacher attrition, lack of parent involvement, and teaching high-stakes testing may hinder progress in education. An education is an indispensable and essential tool, unfortunately, with all the jaded judgments; our students aren’t valuing or able to value their education. An Education can open the doors to opportunities that would have never been possible if it had not been for the knowledge and preparation that one received while in school. With the fluctuating economy and hesitant times, it is more important than ever for our nation’s children to receive the proper education and training that will allow them to acquire a good job and produce the revenue needed to live. Unfortunately, there are many problems facing our education system today, and several of them are having negative effects on the quality of the education our students are receiving. Would one feel comfortable fifty years from now, when the children who are victim of the disadvantages of teacher attrition, lack of parent involvement and a majority of their education being how to take a high stakes test, are running this nation? How soundly can one sleep knowing that their decisions on a bill deciphering how much of a pension someone will receive or what’s legal and what’s not is at stake? Should these problems be quietly swept under the rug and addressed again in another five years, or is it best bite the financial bullet and at the very least, acknowledge there is an issue? A serious problem that is attacking the education system in America is the alarming attrition rate of teachers. Only those not involved with education at all will argue that it is an undemanding profession; in actuality, it is a very demanding profession with an often overwhelming amount of pressure and responsibility tied to it. However, it can also be a very rewarding profession. Unfortunately, many teachers simply cannot overcome the immense responsibilities well enough to stick with the profession for any length of time. Jalongo and Heider (2006) present staggering statistics in their article, saying that forty-six percent of new teachers in this country quit teaching after five years or less, with that percentage growing to fifty percent in urban areas. Even more shocking is the fact that ninety percent of teachers who are hired in this country are replacements for teachers who have left teaching for some reason other than retirement (p. 379). There are many reasons that the rate of teachers leaving the profession is so high. Anhorn (2008) very concisely sums up some of the major problems in her article when she says, â€Å"Difficult work assignments, inadequate resources, isolation, role conflict, and reality shock are some top reasons for the horrendous attrition statistics with the widespread â€Å"sink or swim† attitude that is prevalent in so many schools† (p. 15). It is easy to see why the beginning teacher attrition rate is so high. There is simply so much to do these days, between extracurricular responsibilities and high-stakes testing, it is easy to get overwhelmed. In her article, Sitler (2007) sums it up quite nicely when she says, No one expects the first years of teaching to be easy. No one expects that Teaching assignments will never change. But no one expects either that One’s first years of teaching will be compromised by administrative Systems that make instability and disillusionment routine occurrences Rather than exceptions. (p. 22) If teachers received more support from the administration and less of the strong arm effect, educators wouldn’t be so timid in teaching and instead bring more value to the classroom. Many of us probably remember our parents being very involved with our education, whether they were part of the PTA or just asked about your grades and homework every day when you got home. Unfortunately, today, parental involvement seems to be waning. While there still is a good deal of involvement at the elementary level, middle school and high school, when children really need that parental guidance, it’s almost nonexistent. It is our responsibility to try to involve parents who seem hesitant and reluctant to be a part of their child’s education. No matter what the hesitation is from the parent, be it a language barrier,  fear of school itself, whatever might be causing a parent to be stand offish about their child’s education and being an active part of it, not only the teacher, but administration should use every opportunity to pull a parent in and allow them to become and active part in their child’s education. When parents are involved in education, teens typically have higher grade point averages, higher test scores on standardized and classroom assessments, enrollment in more rigorous academic courses, more classes passed, more credits earned toward graduation, and higher graduation rates. Parents are not performing their duties as first teacher to their kids in education. Many parents left their kids behind and keep putting the blame on the teachers due to their misunderstanding of the No Child Left Behind Act. These parents concerned are the ones who left their kids behind and not the schools; teachers are secondary to kids’ education. Unfortunately so many educators feel such pressure to prepare students for the TAKS test that they fail to ever demonstrate the relevance of what they are teaching. They fail to teach the items within the curriculum that are useful outside of the walls of the school. So, we have students who graduate and can solve quadratic equations, classify living organisms and distinguish between a plant and an animal cell but don’t know how to budget money, complete a financial aid form, solve a real-world problem, think for themselves, or apply the testing information beyond what was taught. I have heard people say the purpose of the exams is to make sure our students do not graduate before they know basics skills†¦ like Physics? Most of the arguments I hear come from people who have never even looked at the test; people who just blindly adhere to the regulations because it is a law. Which leads me to the most frustrating and most often argument I hear which is, â€Å"We need to hold students accountable because it is the law? † Well, there have been lots of bad laws over the years. Does anyone remember the Jim Crow laws? If as a country we were to have blindly followed these laws, then blacks and whites would still be segregated. There is no denying the fact that the problems mentioned, are not going to go away over night. They are major issues facing American education, and educators simply must do everything in our power to conquer them. An education is such a valuable and necessary tool, and we must do everything we can to get our students to value their education. I personally do believe there is hope for a positive change. Problems don’t fix themselves, and if admitting that we need help in going about the way our nation views the importance of education is what needs to be done, then it’s time to slap on the â€Å"HELLO MY NAME IS †¦Ã¢â‚¬  sticker and start being honest and start fixing the problems of teacher attrition, lack of parent involvement and teaching children how to take a state issued test.

History and Geography of India

History and Geography of India Population: 1,173,108,018 (July 2010 estimate)Capital: New DelhiMajor Cities: Mumbai, Kolkata, Bangalore,  and ChennaiArea: 1,269,219 square miles (3,287,263 sq km)Bordering Countries: Bangladesh, Bhutan, Burma, China, Nepal,  and PakistanCoastline: 4,350 miles (7,000 km)Highest Point: Kanchenjunga at 28,208 feet (8,598 m) India, formally called the Republic of India, is the country that occupies most of the Indian subcontinent in southern Asia. In terms of its population, India is one of the most populous nations in the world and falls slightly behind China. India has a long history and is considered the worlds largest democracy and one of the most successful in Asia. It is a developing nation and has only recently opened its economy to outside trade and influences. As such, its economy is currently growing and when combined with its population growth, India is one of the worlds most significant countries. Indias History Indias earliest settlements are believed to have developed in the culture hearths of the Indus Valley around 2600 B.C.E. and in the Ganges Valley around 1500 B.C.E. These societies were mainly composed of ethnic Dravidians who had an economy based on commerce and agricultural trade. Aryan tribes are believed to have then invaded the area after they migrated into the Indian subcontinent from the northwest. It is thought that they introduced the caste system which is still common in many parts of India today. During the 4th century B.C.E, Alexander the Great introduced Greek practices into the region when he expanded across Central Asia. During the 3rd century B.C.E, the Mauryan Empire came into power in India and was most successful under its emperor, Ashoka. Throughout subsequent periods Arab, Turkish and Mongol peoples entered India and in 1526, a Mongol Empire was established there, which later expanded throughout most of northern India. During this time, such landmarks as the Taj Mahal were also constructed. Much of Indias history after the 1500s was then dominated by British influences. The first British colony was in 1619 with English East India Company at Surat. Shortly thereafter, permanent trading stations opened in present-day Chennai, Mumbai,  and Kolkata. British influence then continued to expand from these initial trading stations and by the 1850s, most of India and other countries such as Pakistan, Sri Lanka, and Bangladesh were controlled by Britain. By the late 1800s, India began working toward independence from Britain but it did not come until the 1940s however when Indian citizens began to unite and British Labor Prime Minister Clement Attlee began to push for Indias independence. On August 15, 1947, India officially became a dominion within the Commonwealth and Jawaharlal Nehru was named Indias Prime Minister. Indias first constitution was written shortly thereafter on January 26, 1950, and at that time, it officially became a member of the British Commonwealth. Since gaining its independence, India has undergone significant growth in terms of its population and economy, however, there were periods of instability in the country and much of its population today lives extreme poverty. Government of India Today Indias government is a federal republic with two legislative bodies. The legislative bodies consist of the Council of States, also called Rajya Sabha, and the Peoples Assembly, which is called the Lok Sabha. Indias executive branch has a chief of state and a head of government. There are also 28 states and seven union territories in India. Economics Land Use in India Indias economy today is a varied mix of small village farming, modern large-scale agriculture as well as modern industries. The service sector is also an incredibly large part of Indias economy as many foreign companies have  such places as call centers located in the country. In addition to the service sector, Indias largest industries are textiles, food processing, steel, cement, mining equipment, petroleum, chemicals and computer software. Indias agricultural products include rice, wheat, oilseed, cotton, tea, sugarcane, dairy products,  and livestock. Geography and Climate of India The geography of India is diverse and can be divided into three main regions. The first is the rugged, mountainous Himalayan region in the northern part of the country, while the second is called the Indo-Gangetic Plain. It is in this region that most of Indias large-scale agriculture takes place. The third geographic region in India is the plateau region in the southern and central portions of the country. India also has three major river systems which have large deltas that take over a large portion of the land. These are the Indus, Ganges and Brahmaputra rivers. Indias climate is also varied but is tropical in the south and mainly temperate in the north. The country also has a pronounced monsoon season from June to September in it southern portion. More Facts About India Indias people are 80% Hindu, 13% Muslim and 2% Christian. These divisions have historically caused tensions between different religious groups.Hindi and English are Indias official languages, but there are also 17 regional languages that are considered official.India has several cities that have undergone place name changes such as Bombay being renamed Mumbai. These changes were mainly done in an effort to return the city names to local dialects, as opposed to British translations. Sources: Central Intelligence Agency. (20 January 2011).

Ozone Alert Days and Warnings

Ozone Alert Days and Warnings Ozone is a pale blue gas with a distinctively pungent smell. Ozone is present in low concentrations throughout the  Earths atmosphere  (stratosphere). In total, ozone makes up only  0.6  ppm (parts per million) of the atmosphere. Ozone smells similar to chlorine and is detectable by many people at concentrations of as little as  10  ppb (parts per billion)  in the air.   Ozone is a powerful  oxidant and has many industrial and consumer applications related to oxidation. This same high oxidizing potential, however, causes ozone to damage mucus and respiratory tissues in animals, and also tissues in plants, above concentrations of about  100  ppb. This makes ozone a potent respiratory hazard and pollutant near ground level. However, the  ozone layer  (a portion of the stratosphere with a higher concentration of ozone, from 2 to 8 ppm) is beneficial, preventing damaging  ultraviolet light  from reaching the  Earths surface to the benefit of both plants and animals. Unhealthy Ozone Ozone depletion may be a common news story, but many forget about the dangerous formation of ozone at ground level. The Air Quality Index (AQI) in your local weather forecast may often issue an unhealthy warning based on ground level ozone measurements if ground-level ozone is going to affect people in a particular area. All persons in an area are advised to be on the lookout for health effects related to ozone pollutants when a warning or watch is issued. The Environmental Protection Agency (EPA) warns that although ozone in the stratosphere protects us from harmful UV radiation, low-level ozone is dangerous. Infants, children, and those with respiratory problems may be in particular danger. What Causes Ground-Level Ozone Ground-level ozone is caused when the sun reacts with pollutants from cars and industrial plants to form ozone at or near the surface of the earth. The sunny weather you enjoy in many parts of the world may, unfortunately, be increasing the chances of the formation of ground-level ozone. Summertime is especially dangerous in many traditionally sunny areas, especially those areas with large populations. The EPA issues warnings and advisories for five major air pollutants. ground-level ozoneparticle pollutioncarbon monoxidesulfur dioxidenitrogen dioxide Ozone Alert Days According to associate writer Fred Cabral, â€Å"Ozone ignorance is a problem. Many people do not listen to the warnings given by local forecasters on the dangers of ozone.† While interviewing locals in the area, Cabral discovered 8 reasons why people choose to ignore â€Å"Ozone Alert Days†. Avoiding complacency is key to being safe from the dangers of ozone, Fred indicates, and people should not become complacent about the issue. After multiple street interviews, Cabral has investigated the ways to remain safe. In fact, ozone alert days (sometimes called ozone action days depending on where you live) are days when high heat and humidity cause unhealthy and unsafe levels of air pollution in the ozone layer. Pollution levels are monitored via the Air Quality Index, which was designed by the Environmental Protection Agency (EPA) so that cities and states can measure and report levels of pollutants in our air.

High altitude Essay Example | Topics and Well Written Essays - 1000 words

High altitude - Essay Example The results, as illustrated in figure 1 and 2, showed that there are changes in the cardiovascular system after exercise. There is increased value in both the systolic and diastolic blood pressure and heart rate. The result regarding the blood pressure is consistent with other researches (Kelley & Kelley, 2000) which indicated that there is a progressive increase both the systolic and diastolic pressure. The result regarding heart rate is also consistent with several studies (Arroll & Beaglehole, 1992) which indicated that there should be an increase in the heart rate after exercise. These changes in the cardiovascular system can be associated with the increase in the release of adrenaline after exercise which can cause an increase in the heart rate and blood pressure (Van Hoof et al, 1989). Figure 1. Systolic and diastolic blood pressure at rest and after exercise. (x-axis: subject; y-axis: blood pressure) Figure 2. Heart rate measured in beats per minute at rest and after exercise (x-axis: subject; y-axis: bpm) Also, results showed that there are major changes in the respiratory system after exercise. One observation is that there is an increased value in the respiratory rate (Figure 3). This is consistent with other studies which also showed an increase in the respiratory rate (Posner et al, 1992). ... The decrease in the gas volume can be attributed to the fact that the muscle of for breathing do not work maximally. It is because during exercise, the priority for the supply of oxygen is given to the muscles at work (gastrocnemius, bicep femoris etc). And lastly, regarding the gas composition, it was observed that there is an increase in CO2 while a decrease in O2 after exercise (Figure 5). The increase in CO2 and decrease in O2 is obvious because after exercise because there is a lot of work done. This work utilized more O2 and produces more CO2 through aerobic metabolism (Posner et al, 1992). Figure 3. Respiratory rate measured in breaths per minute at rest and after exercise (x-axis: subject; y-axis: number of breaths per minute) Figure 4. Gas volume measured in liters per minute at rest and after exercise (x-axis: subject; y-axis: liters of gas per minute) Figure 5. Gas composition of O2 and CO2 at rest and after exercise (x-axis: subject; y-axis: percent composition of gas) Al though not observed in the results, there are also some changes in the nervous system after exercise. Physical activity can actually improve cognitive function (Hertzog et al, 2008). Moreover, exercise can also promote protection against neurodegenerative diseases like dementia (Clement et al, 2005). And lastly, exercise can also enhance the release of nerve growth factors, which help the process of neurogenesis (McAuley, 2004). In the report, it is also stated that the students from the football team will go to La Paz, Bolivia for a series of matches during the break. It should be considered that La Paz, Bolivia is located in a high altitude and this might imply some changes in the physiological activity of the body which should be anticipated. It should be noted
