Taking a Look at Relational Databases - 640 Words

Relational databases are the most prevalent in today’s database needs for numerous different applications. These databases go by specific rules and adding in a lot of different attributes involves complexity to the system. Especially in the web applications, it gets harder for the relational databases to handle the capacities and possibilities. The web domain thus, becomes the main motivator for NoSQL. Some of the challenges faced by relational databases were the mismatch that resulted when transforming graphs into tables. On the other hand, when a database was needed only for simples tasks like logging, the relational database had too much more than what was required. Web applications have many different types of attributes which does not fit easily into a relational database, which makes it a burden to handle. For example, videos, text and source code are different types of attributes from the web, which have to be stored in various tables if relational databases are used, because of its strict schema. Qualities like these, make RDBMS, a not-so-wise choice to handle blogs and other web applications. The massive data that has to be taken care of in web applications complicates data handling for famous webpages like Amazon, Google and Facebook. Factors like trillions and trillions of read and write requests which needs to be responded with minimal or no latency, leads these organiz ations to maintain their own hardware in clusters of thousands.

The Garden of Love Analysis Essay Example For Students

The Garden of Love Analysis Essay The Garden of Love is, quite obviously, a poem about life and the pursuit of happiness. It is also about the effects that negativity can have on love. Blake uses religion to convey the idea that negativity pervades and corrupts all life(51 n.9), further supporting it with his use of rhyme scheme and imagery. In searching for love people often times emerge scarred and hostile from their fruitless efforts. Some continue to have faith in the idea of love and its possibilities, others do not. These folk sometimes seek refuge from their pain in a variety of houses. It is just as often that these refugees project their negative attitudes onto others that search for love and happiness. People who fear love can prevent others from finding it, because they change the positive surroundings to suit their negative world. the conflict between organized religion and the individual is the constant idea throughout the poem. Blake, himself, despised the Church, as an institution rather than an idea, and used religious symbols to show how structured religion can destroy the lover and creator within. A chapel has been built, perverting a once pure and loving environment. In inspecting the chapel, the persona feels only negativity from a religious house, as the gates are shut And Thou shalt not writ over the door(6). Not only has man and machine invaded this place once full of life, but they have also brought with them negative commandments. The negative phrase, Thou shalt not defies the instructions in Deuteronomy to write Thou shalt- a positive commandment- upon the posts of they house and on thy gates, supporting the notion that negative commandments pervade and corrupt all life(51 n.9). Other images are used to represent individual and Church, positive and negative. He uses words that exude life and breath, such as green, love, bore, and sweet flowers. These are all positive images that support the individuals search for creativity and love within the natural environment(pre-C hurch). Blake uses negative images to represent the Church, which in turn conveys the effects that negativity and pessimism can have on positive things. Negativity can often overpower positivity. In The Garden of Love negative images invade a positive environment and change it to suit its needs. The Church tears apart the natural environment in order to create a church, shuts the gates to keep out evil and poor people, and replacing the Garden of Love with a garden of death by substituting tombstones for flowers. Blake uses words that imply darkness and negativity, such as new building, gates, graves, black gowns, and briars. The positive images that are present in the first stanza of the poem eventually disappear and the poem is overflowing with negatives. And I saw it was filled with graves,/And tomb-stones where flowers should be:/And Priests in black gowns, were walking their rounds,/And binding with briars, my joys desires(9-12). The images of innocence and life that introduce d the persona finds her place of refuge overgrown with darkness and infected with limitations. As Jean Hagstrum said, It is always the institutional Urizen who perverts natural life. In the garden of love in Experience stands an altar, and priests read commands from a book on a lectern (531). What used to be a place lush with life and hope is being confined by negativity. Blakes use of conflicting imagery shows how negativity is infectious and limits love. Blake also uses the persona to show the effects of negativity on positivity. The persona changes throughout the poem as the influence of the organized Church on the environment increases. In the beginning, the voice is innocent, pure, open, and exploring, saying, I went to the Garden of Love,/and saw what I never had seen/Where I used to play on the green (1-4). The voice was individualistic and not influenced by any powers other than her own. However, as the poem progresses and the persona experiences more negativity, that voice changes. In the final lines, with the addition of internal rhyme scheme, the voice seems trapped and confused. And Priests in black gowns, were walking their rounds,/And binding with briars, my joys desires(11-12). In the first two stanzas of the .u0f3f38a904d5b724a61c1a4478cab02d , .u0f3f38a904d5b724a61c1a4478cab02d .postImageUrl , .u0f3f38a904d5b724a61c1a4478cab02d .centered-text-area { min-height: 80px; position: relative; } .u0f3f38a904d5b724a61c1a4478cab02d , .u0f3f38a904d5b724a61c1a4478cab02d:hover , .u0f3f38a904d5b724a61c1a4478cab02d:visited , .u0f3f38a904d5b724a61c1a4478cab02d:active { border:0!important; } .u0f3f38a904d5b724a61c1a4478cab02d .clearfix:after { content: ""; display: table; clear: both; } .u0f3f38a904d5b724a61c1a4478cab02d { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u0f3f38a904d5b724a61c1a4478cab02d:active , .u0f3f38a904d5b724a61c1a4478cab02d:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u0f3f38a904d5b724a61c1a4478cab02d .centered-text-area { width: 100%; position: relative ; } .u0f3f38a904d5b724a61c1a4478cab02d .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u0f3f38a904d5b724a61c1a4478cab02d .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u0f3f38a904d5b724a61c1a4478cab02d .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u0f3f38a904d5b724a61c1a4478cab02d:hover .ctaButton { background-color: #34495E!important; } .u0f3f38a904d5b724a61c1a4478cab02d .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u0f3f38a904d5b724a61c1a4478cab02d .u0f3f38a904d5b724a61c1a4478cab02d-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u0f3f38a904d5b724a61c1a4478cab02d:after { content: ""; display: block; clear: both; } READ: Rosa Parks Research Essay We will write a custom essay on The Garden of Love Analysis specifically for you for only $16.38 $13.9/page Order now

Understanding Learning

Understanding Learning Free Online Research Papers Understanding learning within humans and non-humans is an area that psychologists have researched over many years. The first major approach was behaviourism which lead to the comparative and cognitive approaches. These two approaches are supported by different physiologists, who have defined methods to help understand learning such as; animals behaviour and the humans mind. These approaches both use experiments, however, they consider different elements to help prove their research, which can be similar and contrast with each other. The comparative perspective in psychology is based on behaviourism; the behaviourist psychologists use mainly experiment to observe the behaviour of animals and other creatures in learning. Researchers propose that learning is potentially observable and measurable and the environment is taking a huge part in studying behaviour in learning. The cognitive perspective come from behaviourism it also uses experimental, but as time goes on the aspects of studying learning has changed. It focuses on more understanding the inferences that happens in the brain processes. The processes in the brain is one of the main aspects of the cognitive perspective. This approach does still have behaviourism as a major element like comparative, however, it also balances it with the mental processes. A method which helps differentiate the cognitive approach is category learning which group things together to help humans organise their experiences. One of the first experiments or studies for category learning was by Bruner at al, who used a method called hypothesis testing. This method of proving and disapproving the hypothesis is not considered by comparative approach. A comparative approach which does uses part of the cognitive approach was part of Tolman’s research. Tolman used classical and instrumental conditioning to find out how the rats behaviour changed and learnt. His experiment focuses on whether the rat learnt from its given environment and adapted its behaviour by taking account the learning within the brain. His experiment combines the comparative and cognitive approach because it makes inference of what is going on in the rats head. The behaviourist Tolman suggest â€Å"that learning involves ‘something in the head as well as a change in behaviour† p181 Tolman The comparative approach usually does an experiment based on condition that observes the subjects behaviour. The researcher will make judgement of the outcome of the behaviour that the subject shown in the artificial environment. The artificial environments which are set up in this approach can also be seen by the cognitive perspective. In Skinners box an environment was set up to monitor behaviour of rat learning how to get food. The experiment involved rat to learn expectancies by giving series of positive reinforcement, which the delivery of food is manipulated by the experimenter which is called operant conditioning. The experiment showed that the behaviour of the rat learnt from the experiment which is applied by the law of effect. The environment of the experiment has a lack of ecological validity due to behaviour of the rat may not be linked closely to humans despite of animals adapt as humans do. In comparison to comparative approach, the lack of ecological validity can also be seen in the Bruners’s card experiment. His work has not got the real life scenario and it is based on an empiricism method. He developed cards which are classed as artificial stimuli, the participants categorised the cards by asking if certain cards were part of the same category and when the participants settled on their hypothesis they wrote it down. This cognitive approach looked at how the mind categorise items, Bruners said that people use two main strategies; successive scanning and conservative focusing. Bruners argue that â€Å"people learn concepts via a process of generating and then refining hypothesis in the light of further evidence†p193 This type of cognitive approach can have several results and there are some human interpretations. Another problem with Bruners hypothesis approach was pointed out by Fodor and Chomsky, known as induction problem. This is when the hypothesis is based on past experiences and there could a number of different hypothesis’s that are correct, which could also contradict each other. This is very different to the empirical nature of the comparative approach seen in Skinners box which gives clear results in the changing behaviour of the rat. The researchers of the cognitive approach shifted from Bruners empirical based experiment to more meaningful categories. Murphy and Kaplan believed the background knowledge was important in category learning. For example, the results of the experiment show that the participants did not try to learn the different attributes they used the background knowledge to link the attributes. However, these two view points of this approach differ from each other because Brunner does not take into account prior knowledge. Murphy’s experiment uses one related attribute and five unrelated attribute of cars. This theme meant that participants learnt twice as quick than those who did not have related theme. In contrast to the cognitive approach the comparative approach takes into account the innate knowledge of the subject. As shown in the Skinners box when the behaviour of rat is observed using its natural knowledge of desire for food. Without this innate nature the rat would not acquire the necessity of learning to get the food. Similar points of view have been suggested using a cognitive approach by Fodor and Chomosky. They both argue that learning comes from innate, which is similar to the Plato who believed that learning primarily came from nativism. They suggested that an alternative to category knowledge is the subject’s innate behaviour. The different approaches that psychologists have studied to help understand learning with animals and humans have meant that there are many methods that can help explain. Comparative with its background in behaviourism tended to monitor events of animals and it was later that physiologists started to make inferences of the brain to try and help explain the results. The cognitive approach identifies ways which humans categorises things depending on our experiences, previous knowledge or innate abilities. The two approaches to learning use very different methods but they also draw on certain similar elements especially when making inferences about the brain.
