World Without Colour free essay sample

No doubt, a World without Colour will be extremely boring. But, one many of us will gasp in disbelief when we understand that various colors seen in this world of objects are actually non-existent. Every object is basically colorless but when it is exposed to solar rays these objects absorb certain colors from the rays and reject others. It is only on this basis that we see ‘colored’ objects. That color not absorbed by an object is sent back i. e. reflected. This reflected light enters our eye and thus we think that object to be of the reflected solar ray’s color. Plants in reality are not green in color since basically they are colorless. But they appear as green because plants cannot absorb the ‘green’ color of solar rays falling on them. Since this green color gets reflected it enters our eye which assumes that the plant is green in color. We will write a custom essay sample on World Without Colour or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page When the green unabsorbed color gets reflected it enters our eyes and thus the latter out of delusion says ‘the plant is green in color’. Yet, a monochrome World be much similar to watching a black and white television. There would be not much variation and everything would be of the same shades, black and white, would be so gray, sad and gloomy.. Colours make nature, fashion, flags and the various races much more interesting and diverse. Without colours, nature would not be appreciated as much as it is coloured. A peach and an apple would look almost identical. There would be no distinct features. There would be no longer a wider range of choices when shopping. Accessories like earrings and necklaces would no longer stand out unless they were really one of kind. Therefore, I strongly agree that without colour, the world would indeed be a boring place to exist.

Memory Memory and Short Term Memory Essay

Memory Memory and Short Term Memory Essay Memory: Memory and Short Term Memory Essay Types of Memory Plasticity: the brains ability to change as result of experience Plasticity is greatest during childhood However, plasticity persists throughout life It occurs by changing the pattern of connectivity between neurons Short term memory: memory for information currently help in current consciousness LIMITED CAPACITY Capacity of STM -this is also known as phonological memory it can be assessed using span tests Miller in 1956 suggested that span is 7 +/- 2 He denotes that these as meaningful chunks of information Capacity is not strictly related to meaningfulness of chunks because: Span length is lower polysyllabic words (skeleton, binoculars, etc) Span length is lower for phonologically similar words (map, cat, etc.) another thing that can influence span is the opportunity to rehearse the material span is reduced if participants are asked to silently mouth irrelevant speech while encoding a list This is known as: Articulatory suppression silently mouthing words while performing some other task. Developed by Baddeley Baddeley found that recall of word lists from STM is reduced for longer words and affected by articulatory suppression Span tasks involve two components: a phonological store and a rehearsal mechanism based on subvocal articulation that refreshes the memory store ALSO KNOWN AS: the phonological loop Articulatory suppression impairs the subvocal articulation that refreshes the memory store. How do STM and LTM interact? Atkinson and Shiffrin created the modal model of memory According to the MODAL MODEL information can only get into LTM, and get out of it again, VIA the short term system Model assumes that amount of time in STM predicts later learning STM is characterized as mostly verbal info. *** LOOK AT DIAGRAM IN BOOK -this model divides memory into very short-lived sensory registers a general purpose short-term store and LTM -HOWEVER, empirical memory does not support this model things don’t have to spend along time in STM for it to go to LT How it actually works! -STM is important for LTM BUT, contemporary components suggests that there are various components and each component is material specific Damage to a specific component will affect learning of that specific material rather than learning per se. -it has been suggested that there is a STM capacity for visuospatial information this suggests a role in visuospatial STM in long term learning of visual information Working memory: a system for the temporary storage and manipulation of information An extension of short term memory because you can manipulate info as well Emphasizes a wider role in cognition (reasoning, comprehension, etc.) WHEREAS, short term is often taken to imply a passive retention of material Thus, WM involves the retention and processing of info. In a limited capacity short-term store The prefrontal cortex (PFC) is responsible for refreshing info in the stores (rehearsal) –and manipulating that info E.g. using a list of #’s in STM to perform calculations In general, a network of regions are involved with conjoint activation of both frontal regions (involved in manipulating and retrieving information) and posterior regions (involved in storing of material). 1. Model of WM (Atkinson & Shiffron) Verbal memory vs. visuospatial memory a. Parts of STM that are specialized for these distinctions (mentioned above in STM section) The phonological loop and visuospatial sketchpad are known as Slave Systems a. Central executive = TRANSFERS/TRANSFORMS information from either the loop or the sketchpad Thus, the central executive coordinates the slave systems, and cognition in general, by retrieving things from memory, specifying task goals, and initiating and terminating cognitive routines It is the interaction between the flexible executive system and the more specific processing routines that is the ESSENTIAL characteristic of a WM. Now how long term memory

Comparing Role of Race between Rodriguez in Blaxicans and Other Essay

Comparing Role of Race between Rodriguez in Blaxicans and Other Reinvented Americans and Baldwin in Stranger in the Village - Essay Example This research will begin with the Rodriguez viewpoint and experiences of race and racism. A race is separate from culture and ethnicity: Rodriguez addresses the issue and dilemma of American immigrants and the changing notion of a race at a period when cultures spread beyond a nation’s borders. He admits that immigration would continue to facilitate racial variety to introduce people of different cultures and origins in the complex American society. As a result, Rodriguez points out the diminishing differentiation of a black and white race in America and demonstrates the transforming America, where residents and immigrants acquire new identities through categorization. Irrespective of the racial variety, he emphasizes that racial mixture should serve as a point of pride and promote diversity through cultural assimilation and reinvention, rather than maintaining the separate thought of ‘selves’. Rodriguez supports American categorization as introduced by late presi dent Nixon, convinced that it’s not about race, but blending people with more of their cultures, ethnicity, and environment. This would ease the tension of racism and assist sway people away from the idealized black-white divided thinking. For example, categorization of Black, Hispanic and Asian among others introduces the ethnic and cultural elements. While Black is a race, Hispanic is more of a culture and related to environmental origins and only fits the definition of the North American world. Hispanics could be black, Indian, and from different countries hence not a specific race. Viewed in this sense, a racial mixture is not a negative thing in a society.

Case Study 3 Example | Topics and Well Written Essays - 750 words

3 - Case Study Example This paper will focus on two major technologies i.e. cloud computing and virtualization that can be adopted by BP to support its current strategy in its quest of transforming its business operations and ensuring it is no longer a serial underperformer. Virtualization refers to a way of creating virtual version of devices or network resources e.g. storage devices, servers, network or operating system. (Lans, 2012). In this case, the framework divides the resource being virtualized into one or more execution environments. In this case of BP, virtualization can be applied by combining its resources i.e. serves so as to serve as one. This is advantageous in a way that having a central server will lead to increased processing power hence faster data processing. Having one central server means BP will incur less costs in buying less hardware and also reduced energy costs since less hardware means less power consumption. (Roebuck, 2011) Fewer personnel will also be required to manage and maintain the equipment hence Dana Deasy’s dream of centralizing and cutting down costs of BP will come true with the adoption of virtualization. With virtualization, BP can create a strategic business environment in terms of resource use and operation with business partners and suppliers. This can be done through the firms intranets and also via external networks i.e. extranets and the internet. This will present BP with a collaboration opportunity of sharing information, resources and ideas with other people and the company hence helping the company respond in timely manner toward situations. (Rainer & Cegielski, 2012). Cloud computing refers to sharing of computing resources over the internet instead of using local servers to support applications. (Marks & Lozano, 2010) For the case of BP, the company through the advice of the CIO can choose to software-as-a-service where they will subscribe to an application but access over the internet. BP can also use

Russia, Democratic or Not Essay Example for Free

Russia, Democratic or Not Essay Russia should be considered a semi-democratic country. They have the characteristics of a democratic country, yet at the same time they dont. For example, they have freedom of speech but to an extent. As shown in a round table discussion show thats been on air for years. But, its only good things are spoken about the government and Putin. Also they can vote and what not but the government tries to rig it. Another example is that people may oppose the government, but may not publicize it widely. A show of this would be like the man that broadcast his ideas about the government on the radio, but he is only aloud to at on station. Any other station has him blacklisted. So not many people hear his ideas. Another problem is there freedom to assemble. They can do this but only with the permission of the government. Also they sometimes pay kids to participate in rallies that oppose anyone against the government and Putin. And lets not forget about the private owned businesses because these are essential. In Russia businesses can be privately owned to an extent plus they can choose what to sell and how much, also they decide who they hire. Also, the Russian Federation confirms a citizens right to state healthcare and medical assistance free of charge. Citizens do not pay for this but instead companies and government subsidies do. Plus the health care is poor. They may have well trained doctors but indecent equipment. This is a helping cause in the reason why the death rate is higher than the birth rate. The life expectancy is also low. These are all signs of a semi-democratic country.

Alexander The Great Essay -- essays research papers

Alexander The Great was one of the greatest emperors and leaders of the world. In fact, he was the only emperor to be called, "The Great." He had studied under a great Greek Philosopher, Aristotle, who taught Alexander literature, science, medicine, philosophy and to speak and write well. Alexander was the son of Philip of Macedonia.
