Environmental Problematic in essays

Environmental Problematic in essays Environmental Problematic vs. Industrial revolution The common Japanese expression, mizu ni nagasuliterally, "let it be washed away," or to settle a dispute by letting bygones be bygonesoriginated in the belief that any and all troubles can be purified by nature. (nira.go.jp/publ/review/99summer/mori.html) Because Japan has always had a thriving and rich natural environment, Japanese people have for a long time taken this natural bounty for granted. In the late 1960s, however, environmental mayhem resulting from industrial pollution caused alarming damage to the people of Japan. For the first time, policy-makers and ordinary people alike began to recognize "the environment" as a problem... otherwise known as the environmental problematic. During the last thirty two years after the establishment of the Environment Agency in 1971, the environmental situation at the national and global levels has undergone substantial changes in Japan. At the national level, notable achievements have been made in combating severe pollution during the period of high economic growth. However, air pollution in major urban areas and water pollution caused by industrial expansion are some of the dynamics that continue to impose themselves as heavy factors in the environmental problematic. Increased severity of global issues such as depletion of the ozone layer and global warming are playing a national and political roll in defining state policy within Japan. This paper will describe some major environmental problems in Japan, several Japanese environmental policies, the process of implementing these policies, and how they are maintained through the Japanese political system. After the Second World War, Japan emerged as one of the three dominant players influencing the global environment and the direction of international environment protection. The structure of Japans industry has drastically changed over the last few decades w...

Without further ado, here are 10 facts on the spatial order in human visual perception: The human visual perception is far beyond our imagination. When we see our Earth’s surface, it appears that we can see nothing more than a few kilometers that lead up to the horizon. This is because the surface of the Earth literally curves out of sight after 5 kilometers.If the Earth’s surface were to be flat on the other hand, you would see a flickering candle flame even 48 kilometers away. In addition, our naked eye can see the Andromeda galaxy, which is located 2.6 million light-years away from Earth. The source of light that enters our retina travels from 1 trillion stars in the galaxy. Technically, we can see the color red with our naked eye, but in theory, it’s quite the opposite. Some scientists believe that the retina has receptors similar to that of an RGB (red, green, blue color spectrum) monitor. However, the eye’s retina can’t detect red shades. The so-called â€Å"red† receptor actually detects yellow-green hues whereas the â€Å"green† receptor detects blue-green colors or hues. These colors are then differentiated by our brain which tells us to see red colors. Selig Hecht, known for his remarkable work on human eye perception, made an accurate measurement of the human vision’s absolute threshold in 1941; i.e. the number of photons that must strike our retinas in order to stimulate the brain with visual awareness.The study that led to such a remarkable discovery was performed under ideal conditions where participants were allowed to adapt to total darkness; flashlights of 510 nanometer blue-green wavelength, acted as a stimulus, to which the human eye is most sensitive. It was concluded that our brain interprets vision when the retina is exposed to 5 14 photons. The human eye perception is limited to a certain degree. We are only able to see colors between 350 to 700 nanometer wavelengths. This is why we are not able to perceive ultraviolet and infrared colors. Ultraviolet colors fall in shorter wavelengths than 350 nanometers, whereas infrared colors are longer than 700 nanometer wavelengths. For example, when you take a look at bananas, you see the color yellow because they bounce off color wavelengths of 570-580 nanometers, when hit by full spectrum light. Have you ever asked yourself why you see things in 3D? Our brain is responsible for reconstructing images which let us experience life from a 3D perspective. This is because we have a pair of eyes that gives birth to a phenomenon known as Binocular Disparity – a slight difference in perspective between the left and right eye. Binocular disparity plays a vital role in giving depth to a scene. Convergence is another phenomenon which signals the brain to create depth of field, particularly when you are focusing on something close to your eyes. While we can see and perceive colors at the center in high resolution, our peripheral vision is very low in resolution – it’s blurry and nearly monochrome. However, we don’t actually see our peripheral vision as a monochrome image because our eyes and brain are quick enough to fill in the required details as soon as we become aware of this fact. It takes time for the human eye to perceive visual depth of a scene. The brain of a newborn child is not fully developed and must adapt to the new environment first before learning to construct a three- dimensional perspective. A study on infants has revealed that it takes a two months old baby to construct depth awareness of an image. Human visual perception is able to â€Å"adjust† to the dark by activating its own ‘night vision mode’. The neural pathways of the brain recalibrate themselves chemically to turn on scotopic vision circuits. These circuits are normally off during the daytime and require 20 minutes of darkness to be active. Scotopic vision circuits do not adapt to colors other than blue, as their receptors are blue-sensitive. You might have noticed how everything tends to take a bluish hue when you are trying to see in the dark. Ever thought why you can see the stars twinkling and shining at night? It’s because these receptors are very sensitive to even minor fluctuations in light. The brain is the main asset behind our visual perception. The eyes are merely tools to perceive light and transfer it to receptors that signal the brain to form images. The brain is, for a fact, the main component that constructs images and enables us to see perfectly. For example, our retina captures and interprets everything upside down, but still, we see everything the right side up. There are 100 million photoreceptors in each eye that enable us to see crystal clear images. However, there is only a million nerve fibers that act as a bridge to the eyes and brain. So, technically speaking, the resolution of our eye is not more than 1 megapixel. These facts will help you come up with your own topics and create masterpieces.

The impact of stock market volatility on monetary policy Dissertation

The impact of stock market volatility on monetary policy - Dissertation Example This section presents the results of the estimation. In table 1 we present the results of running regression specifications (1) and (2) using OLS and GMM instrumental variable estimation. We have used the S and P 500, Dow Jones as well as the FTSE 100 indices as measures of stock market prices. All three have been included to verify whether the results obtained are robust to changes in stock market indices. For the GMM estimation, lagged values of inflation and the output gap have been used as instruments. Finally, we have incorporated a recession dummy in the 2nd specification. This dummy variable takes the value 1 for all quarters between 2007 Q3 and 2009 Q4. In table 1, the 1st column presents the results of running a simple OLS regression on equation (1). The intercept and the coefficient on inflation are positive and significant. However, the coefficient on the output gap, although quite large is not statistically significant. Thus, from the 1st column where the estimation was c arried out of equation (1) we find that the interest rate responds only to the inflation. It does not respond to the output gap. Also, from the last row which presents the Wald test statistic which tests the hypothesis ÃŽ ² = ÃŽ ³ = 0.5, we find the statistic is highly significant. So, the null hypothesis is rejected by the 1st model.   In column 2, the results of estimating the OLS specification (2) are presented. The wald test statistic is 89.25 which is highly significant.... This translates into the query of whether equity price levels as measured by indices such as the Dow Jones or the Standard and Poor 500 should be targeted explicitly by monetary policy or not. Most macroeconomists however are of the opinion that pursuing these queries is not worthwhile since targeting stock market prices requires identification of what the fundamental prices of an asset is before the extent to which the actual price has deviated from the fundamental or target price can be identified. In other words, ex-ante identification of a stock market bubble is extremely difficult. Since the fundamental price of a stock is not verifiable then the nature of deviation of actual prices remains unverifiable as well (Shiller, 1989; Salge, 1997). Bubbles, i.e., increase of prices steadily above fundamentals can be identified ex-post. In hindsight it is clear that the Nasdaq rise or the steady rise in Japanese asset prices in the late 1980’s were such bubbles. But during the res pective phases these movements were not convincingly identified as anything other than reflecting fundamental price dynamics. Therefore under these difficulties of recognising stock market volatility in real time the true complexity of asking what the reaction of monetary authorities should be becomes clear. One possible direction suggested in literature is to make the simplifying assumption that the monetary authority is aware of the presence of a bubble and realizes that the collapse of the bubble is imminent. Post-collapse prices will revert back to the fundamental levels. Then ask what the appropriate reaction of the monetary authority should be under such assumptions.
