Degas Private Life of a Masterpiece Little Dancer Aged Fourteen Assignment

Degas Private Life of a Masterpiece Little Dancer Aged Fourteen - Assignment Example aining the young girl aged fourteen called Marie, he takes and mould many parts of her body, and finally after that Degas comes out with an audition of the little dancer aged fourteen. The public did not receive this theme warmly or with full acceptance but instead the public warned their children against dancing and refer to it as misleading to the young generation. With young people, things were different, instead they liked it more and it triggered many young female to join the dance, this extends until today young people like dancing a lot. Degas makes it more attractive by painting the ballets dancers, he spends much of his time watching the dancers this is because he is more attracted towards young female dancers. Degas liked the artwork just from the time when he was young. He and he worked on his talent until when he meet his dancers in Paris city. This triggers him to work with extra effort and comes out with the theme the little dancer aged fourteen. This is after meeting the young girl by the name Marie who was so determined with dancing and sculpting as a special art in her life. Degas took her after realizing that her mother and her entire family were very poor. Degas emphasized on training and strong body movement. This was the drill that he used to archive a perfect dancer as far as his tile is concerned. By doing this he only concentrated on young people who were referred as children, this was the only controversy that he had against the public and more so they were female and not male. With Degas, he was using the young women so that to bring out the aspect of capability and self esteem. With the posing, the special dancing, and especially the final posing it was unique and not very common this made his dancing art very powerful. Apart from that, also Degas concentrated on the material that he was using in his artwork since it is also a major aspect as far as stage presentation is concerned. It appeared to be very unique also and so much

Conclusion With all the advantages that hybrids have to offer, it’s something a new car consumer should seriously consider. One person can make a difference! Hybrid 4 Gas prices are up 23% from a year ago and global warming is a constant fear of scientists and people alike. What then can one person do to help the current situation of gas and pollution? Buy a hybrid car! Hybrid sales have doubled in the past year and according to J. D. Power and Associates, hybrid sale should hit 200,000 in 2005. Within 20 years, Toyota’s top guy in the U. S. , Jim Press, thinks almost every car on the market is going to be a hybrid. So what exactly is a hybrid car and what are all the things a consumer should look for when buying one? Here are some specifics; the good and the bad. A vehicle is considered hybrid is the source of power comes from two sources. A hybrid car combines gasoline and electric power. The car has a normal gas tank, but also a set of batteries. The batteries are recharged every time the person drives the car so there is no need to plug it in like very old, original electric cars. Instead of having just a transmission, the batteries provide electricity to an electric motor which then turns the transmission. There are two different types of hybrid cars. One is a parallel hybrid. This has a fuel tank and batteries and both the engine and batteries turn the transmission over at the same time. Both the electric motor and gas engine can provide power. The other is a Series hybrid, which has a generator. Gas turns the generator and that can either charge the batteries or power the motor. The gas engine never actually powers the car. The electric motor of a hybrid car is very sophisticated. It works as a motor and generator and draws energy from the batteries. The batteries store energy for the car and the motor can either draw energy from them or recharge them. Hybrid 5 So what are some advantages of owning a hybrid vehicle? This is going to look at environmental, national, federal, and economic advantages of having one. First is environmental. â€Å"A car that burns twice as much gas to go a mile will generate approximately twice as much pollution. † (Nice, Karim. ) A gallon of gas weighs about 6 pounds and when it’s burned off it produces almost 20 pounds of carbon dioxide. In the U. S. alone, cars and trucks consume 8. 2 million barrels of oil EACH DAY which calculates to over 300 million tons of carbon each year. This is the largest part of carbon dioxide emissions, even more then factories and homes. If cars and trucks improved by just 5 mpg, Americans could save 1. 5 million barrels of oil a day or 55 million tons of carbon a day. Decreasing fuel consumption therefore reduces emissions. There is also carbon dioxide that cars release into the air and that scientists believe contribute to global warming. Again, twice as much gas leads to twice as much carbon dioxide. If saving the environment still sounds like something too big for one person and one at a time, here is a more personal thing to consider, the effect that vehicle air pollution has on the human body. It can cause problems such as decreases in lung capacity, acute respiratory problems, reduces the release of oxygen to body tissue, contributes to birth defects low birth weight, infant death, and makes otherwise healthy kids 3 to 4 times more likely to develop asthma. There are also concerns on the national level. Even though our consumption of oil is ever increasing, our production of oil has gone down since the 1970’s. For most of the 20th century, we made so much oil that we had enough left over for export. But now Hybrid 6 America relies on imported oil. â€Å"In 2001, imported oil accounted for 55% of US consumption; this figure is projected to rise to 70% by 2020. † (http://www. hybridcars. com. ) Nearly two-thirds, or 80%, of the world’s known oil reserves are under just six Persian Gulf nations: Saudi Arabia, Iraq, the United Arab Emirates, Kuwait, Iran and Qatar. This forces the U. S. military to stay in foreign bases to oversee our free excess to oil, it arouses hostility from those in these countries who have anti-American feelings, and the production of oil in these countries only benefit world super-powers and make the rich richer and the poor poorer leading to more hostile feelings toward America. Some also go so far as to say us paying these countries for oil is providing terrorists with great sums of wealth, which they use for organized anti-American endeavors such as the plane high-jackings of September 11th. Ever since September 11th, Americans are leery of relying on gulf countries for our oil supply because rely is exactly what we do. The gas prices we pay reflect what other countries charge for their barrels of oil. Increasing efficiency of cars and trucks can play a role in reducing our dependency on foreign oil. By raising fuel efficiency by just 2. 7 mpg, Americans can save enough to extinct all oil imports from Iraq and Kuwait combined. By raising it 7. 6 mpg, Americans could eliminate 100% gulf oil imports! And, in President Bush’s energy bill proposal, he said he wants to use empty military bases as oil refineries in order to increase our supply, but instead of relying on government, individuals can really impact our part in buying foreign oil by getting better gas mileage and basically using less. Hybrid 7 There are also the federal level incentives the think about when buying a hybrid vehicle. The Clean-Fuel Vehicle Deduction tax break was given during this season. People who bought a hybrid in 2004/05 could claim up to a $2000 deduction when they do their taxes. In 2005/06, it’s scheduled to drop to $500, but if a new energy bill passes the number will go back up. There are also local incentives to buying a hybrid. If a person bought one in San Jose, CA, they are exempt from local parking fees. Colorado offers a tax credit. Connecticut exempts the sales tax on a hybrid meeting certain requirements. In Florida and Georgia people who have hybrids can use the high occupancy lanes at any time of the day and no matter how many people are in the car. And Illinois has a program called The Illinois Alternate Fuels Rebate Program which pays 80% or up to $4000 to convert your vehicle to an alternate fuel system. On to mileage. This is a big one that car consumers are looking at today. Instead of getting the average 15 to 26 mpg, a hybrid can get anywhere from 50 to 60 mpg! That’s a huge difference! This is achieved because hybrid vehicles convert energy that is normally wasted when a person coasts and breaks into electricity, which is then stored into the batteries until needed by the motor. The motor is also used to assist the engine when going up hills or when the car is driving in low speeds. Low speeds, like city driving are the least efficient fuel conditions. Some hybrids also automatically shut off the engine when the car comes to a stop preserving the fuel and energy. Some websites have online calculators that measure your own car up against a hybrid of your choice. I used one to measure my own car and got these results. If a person typically drives 10,000 miles a year and pay the national average of $2. 10 per gallon and gets 23 miles per Hybrid 8 gallon, this is what a person would save if they had a hybrid: 235 gallons of gas, 4,696 pounds of carbon dioxide, and $493 a year. (Stern, Linda. ) For this online calculator, I used http://www. hybridcars. com/calculator/index. php to compare my car with a new Lexus RX, which is a hybrid vehicle similar to my own. This website allows you to put in what make and model your car is and compare it to any hybrid vehicle to see the difference in consumption and cost. Hybrid 9 So are there really any downsides to owning a Hybrid? Almost every car review only state one flaw, and that’s the price. A 2005 Ford Escape Hybrid base cost $27,560. The Toyota Highlander Hybrid with four-wheel drive costs $39,290. And the most popular, Toyota Prius, cost around $27,000. The sophisticated computer control that makes everything work in these cars makes is what makes them expensive, at least more expensive then their non-electric counterparts. Also hybrid owners complain that they don’t actually get the mileage they are supposed to but that can be said for every car since too many factors go into affecting your mileage per gallon. With all the advantages such as helping the environment and saving ourselves from being so dependant on foreign oil, not to mention helping our health and our own personal wealth, most feel the added price of a hybrid vehicle is not something to hard to overcome. New car consumers should seriously look into whether a hybrid car is the right choice for them because this really is something that individuals can do to better our world. Hybrid 10.

A Midsummer Night’s Dream by William Shakespeare Essay -- Helena, Nick

Being that A Midsummer Night’s Dream is a Shakespearian comedy where passion is a significant theme. It is perceived in a variety of ways such as passion for revenge, recognition, and for love, which have the potential to blur the lines between the levels of social hierarchy. Shakespeare uses a variety of characters such as Helena, Nick Bottom, and Oberon to express the theme of passion and its significance in the play. Helena represents the passion for love in this text, as she runs after Demetrius into a forest seeking love between them, even after Demetrius has told her to stay away. This passion for love is significant to the play, because this play is displaying how love triumphs the social hierarchy, even though magic is a deciding factor. â€Å"The more I love, the more he hateth me† (I.i.199). Helena says this of Demetrius as her love to him is deemed unwanted and repulsive. Her passion for love is so strong that she is willing shed blood for it, â€Å"I am your spaniel. And Demetrius the more you beat me, I will faun on you. Use me as your spaniel, spurn me, strike me, neglect me, lose me† (II.i.204-206). Even to an extent where she would die for Demetrius, â€Å"Stay, thou kill me, sweet Demetrius† (II.ii.84). At one point in the play Helena loses her sight of having a passion for love, when Demetrius and Lysander both fall head over heels for Helena, she can't believ e them. It seems Helena has disbursed so much time rationalizing why she isn't loved that, when the moment comes along whether it is reality or falsehood, she can't embrace it and enjoy it for how it is seen. She develops even more self-pity for herself when she trusts that she has gone from being unloved to a person of pure mockery. As time passes her love for Demetriu... ...caused devastating winds, flooding, and harsh rainfall destroying crops are examples of a leader of power. Depending on the leader’s behaviour and action, it will decide between punitive tornado or a gentle breeze. To conclude, A Midsummer Night’s Dream is a play that displayed its main theme of passion through the various ways mentioned; passion for revenge, recognition and love. This play being one of Shakespeare’s most amusing works helped reveal the key idea as he managed to balance both comedy and passion, showing the audience how the boundaries of social hierarchies can be blurred. Helena, Nick Bottom and Oberon all had passions so powerful and potent that they effect different biospheres of the social hierarchy. Works Cited Shakespeare, William. A Midsummer Night’s Dream. ED.

Crime and Victimization Essay

Crime is an unfortunate part of many people’s lives – both for the victim of the crime and also the suspect. There are many theories as to why crimes happen, who commits the crimes, and why crimes happen to certain people. Not all crimes can be solved, or questions answered but these theories give a peek into the thinking or background behind some crimes that are committed. Social process theory believes that individuals are socially conditioned into or against crime (Siegel, â€Å"Social Process Theory†). Negative family relationships, limited education or association with others who have little or not respect for the law, can have a significant impact on a person’s life. The case of Christopher Newsom and Channon Christian, is a perfect example of this theory. Christopher and Channon, both 21, were on a date in January 2007, in Knoxville, Tennessee when they were carjacked and abducted late at night. They were taken to the house of a man named, Lemaricus Davidson where they were tortured and eventually killed. This terrible murder was not only the act of Lemaricus Davidson, but four additional individuals: Letalvis Cobbins, George Thompson, Eric Boyd and Vanessa Coleman (Channon Christian, Christopher Newsom murders). Social process theory believes if a person associates with criminals, they are more likely to engage in criminal activity themselves. Over a period of hours, these five individuals slowly tortured Christopher and Channon. They suspects were all involved in this horrific crime and did not attempt to stop each other. With various local, state and federal organizations/agencies, depending on the crime(s), one or more organization/agency can be involved. A majority of routine traffic stops and arrest and done by local law enforcement. Sometimes, if a pursuit entails, more than one agency may be involved, especially if the pursuit crosses into another county or state lines. More serious crimes, involve federal agencies. This type of crime would involve acts of terrorism, money laundering, drug trafficking or serial murders. One recent crime would be three murders in Cleveland, Ohio by a convicted sex offender (Associated Press). In this case, because of the number of victims and the possibility of additional victims, both the local Cleveland Police Department and the FBI are involved in this case. Cleveland PD is involved, because the crimes happened in their jurisdiction. The FBI is involved in this case as well, because they are dealing with a serial killer and there are potentially additional victims that have not yet been discovered. In a case like this, the various organizations/agencies work together to try to solve the crime and gather evidence. Just by reading your local newspaper, you will find that a number of crimes happen in your own community. Recently, in a local community in Virginia a 25-year-old man was charged with murder and robbery, when he shot a 55-year-old man who was out walking his dog around 9:40 PM. Police report that the victim was approached by the suspect, shot the victim and robbed him and then fled the scene. Police were given the description of the man they saw fleeing the scene. It was also reported that the gun used in this crime was stolen from a car in a local neighborhood (Aric Alexander Smith). Not all crimes are preventable; sometimes criminals are determined to commit a crime for one reason or another. In this case, it may not have been preventable but steps could have been taken to possibly deter activity like this. Sometimes, increased patrols can deter car breakings and confrontations just simply because there is a visual presence of law enforcement. Many neighborhoods have adequate lighting with the idea of a better-lit area may have less criminal activity. Law enforcement also educates the community on how to protect themselves and their home when walking late at night, going on vacation and some even offer self defense classes (Siegel and Worrall, 99). Crime is an ugly side of our society, but measure can be taken to possibly avoid certain situations or to make oneself less likely to become a victim. There are many tips and suggestions on things such as even visiting an ATM or going to the bank, to make yourself not stand out or become a victim of a robbery – be prepared when going to an ATM, make sure you don’t have to dig  in your pockets or your purse; use an ATM in a well lit area; be aware of your surrounding. Simple things like this could help one’s chances of becoming a victim. Not all crime is avoidable, but we can do what we can to try and make it less likely to happen. References Siegel, Larry J. (N.

Hot Wire Laboratory

THE UNIVERISTY OF MANCHESTER SCHOOL OF MECHANICAL, AEROSPACE AND CIVIL ENGINEERING LABORATORY REPORT INSTRUMENTATION AND MEASUREMENT VORTEX SHEDDING FROM A CYLINDER & DATA ACQUISITION NAME:MANISH PITROLA STUDENT ID:75050320 COURSE:MEng MECHANICAL ENGINEERING DUE DATE:27TH NOVEMBER 2012 1) What are the main advantages and disadvantages of using a hotwire to measure flow velocities?There are many advantages and disadvantages of using a hotwire to measure flow velocities, one of the main advantages is the hotwire produces a continuous analogue output of the velocity at a particular point, and hence information about the velocity can be obtained for any specific time. Another advantage of using a hotwire anemometer is the ability to follow fluctuating velocities to a high accuracy. Also another advantage of using a hotwire anemometer is the sensor is able to relate the voltage and the velocity using hotwire theory. However even though hotwire anemometer is an adequate tool to obtain data it has its drawbacks. Read this  Respiratory ActivityOne disadvantage of using a hotwire is that it has to be calibrated due to the theory not coinciding with actual data and the hotwire can only obtain the magnitude of the flow and not the direction. Another disadvantage of using a hotwire is the unsystematic effects that occur such as contamination and probe vibration. Some systematic effects that affect the data are the ambient temperatures and eddy shedding from the wire. One of the main disadvantages of using a hotwire is the output depends on both velocity and temperature, so when the temperature of a fluid increases the measured velocity obtained are too low and adjustment is required. ) Why is setting the correct sampling rate important in digital data acquisition? What experimental parameters or requirements can be used to establish the optimum sampling rate? What may happen if the wrong sampling rate is used? Using the correct sampling rate is important because if the incorrect sampling rate i s used some aliasing effects may occur, presenting insufficient data where important data is ignored if the sampling rate is below the optimum, and if the sampling rate is above the optimum more accurate data is obtained which carries the same trend as the optimum with few distortion which are not required.This can cause inadequacy of the data, where recording is not frequent enough or too frequent. The optimum sampling rate can be established using the Nyquist theory which states that the maximum measures frequency is half the sampling frequency, however the bandwidth of the signal needs to considered, the rule for obtaining the sampling frequency of any probe must be at least 2. 5 times greater than the maximum frequency present. 3) Show how the sampling rate was determined for this experiment.What was the sampling rate? For a flow around a cylinder an empirical relation between the vortex shedding frequency and Reynolds number (Re) is used to find the sampling rate. The relations hip below is used to find the frequency in the flow where the Strouhal number is 0. 2, diameter (d) is 15mm and the free stream velocity (U0) is 10m/s. St=fdU0=0. 1981-19. 7Re? 0. 2 Then by simple algebraic rearranging the frequency is found to be 133. 3Hz. Therefore the maximum frequency experienced is 2f = 2*133. 3 = 266. 6Hz.To obtain the optimum sampling frequency we simply by using Nyquist theory multiply the maximum frequency by 2. 5 providing an optimum sampling rate of 666. 5Hz. The values for the sampling rate were taken as 330Hz, 660Hz and 1320Hz for experimental purposes to study the over and under sampling of data. 4) In the experiment the hotwire was calibrated in terms of velocity vs (E-E0)2. Plot out the calibrations for U = B((E-E0)2)n and the various polynomials. Compare the different lines. Which is the best to use? Figure [ 1 ] Figure [ 2 ] Figure [ 3 ]Figure [ 4 ] From the above graphs is can be seen that the best calibration to use is the cubic calibration (figu re 2) as this fits the actual velocity line more accurately. 5) If the velocity higher than the ones calibrated foer was measured, which calibration is likely to give the best extrapolated data? Figure [ 5 ] Figure [ 6 ] Figure [ 7 ] Figure [ 8 ] From the above graphs it can be seen that the worse extrapolated data is found using the quartic calibration and the best extrapolated data can be found using the linear calibration of A([V-Vo]^2)^n.Also higher order polynomial extrapolation can produce invalid values and as a result the error will magnify as high order of polynomials are used, so therefore the linear relationship is recommended. 6) In a fast Fourier transform (FFT) the data in the time domain is converted to the equivalent data in the frequency domain. The original data can therefore be considered as the sum of a series of sine waves of regularly spaced frequencies, with different magnitudes and phases. How is the frequency interval in the FFT determined? How can the frequ ency interval in an FFT be reduced?What impact could this have on an experiment? The frequency interval can be obtained by dividing the sampling rate by the number of samples used. For 660Hz the number of samples is 1024, so therefore the frequency interval is 660/1024 = 0. 6445. The frequency intervals can be reduced by increasing the number of samples used; this is advantageous as it gives a more accurate representation of the original signal. 7) Considering the FFT data, what can be done in an experiment to isolate genuine signals from random fluctuations in the data? Give an example of this in graphical form.Figure [ 9 ] Figure [ 10 ] From figure 9 it can be seen that the peak is unobtainable as the data is very noisy which could be due to disturbances. However this can be overcome by averaging the FFT which allows us to easily identify peaks which can be seen from figure 10. 8) In this experiment, why are 2 frequency peaks seen on the FFT when the hotwire is near the centre lin e? 2 frequency peaks can be seen on the FFT at the centreline due to the 2 vortices induced by the cylinder but as you move away from the centre line only one of the vortices is predominant.The two peaks occur at 129Hz and 250Hz. 9) With increasing distance from the centreline, how does the FFT distribution change? Include graphs to illustrate this for various locations across the wake. From the below figures it can be seen that as you move away from the centre line the peaks in the FFT distribution disappear. Figure [ 11 ] Figure [ 12 ] Figure [ 13 ] Figure [ 14 ] Figure [ 15 ] Figure [ 16 ] 10) Plot the probability distribution histograms of velocity for various positions across the wake.What does the histogram show and how can the variation in the histograms be explained in terms of the properties of the flow? Figure [ 17 ] Figure [ 18 ] Figure [ 19 ] Figure [ 20 ] Figure [ 21 ] Figure [ 22 ] By comparing the above probability distribution figures it can be seen that with distanc e away from the centreline the flow velocity develops a more uniform velocity. It can be seen that within the 40mm distance away from the centreline, the probability distribution of the velocity produces wide distribution of velocities; this is due to the various velocities inside the wake and turbulence.For distance more than 40mm away the probability distribution of velocity becomes more uniform, which implies the vortices play no role in affecting the flow at these distances away from the centreline. It can also be seen that the flow speed at these distances increases as the flow diverges and accelerates around the cylinder. 11) Plot a graph showing the variation of mean velocity, RMS velocity and turbulence intensity with distance across the wake. What physical phenomena in the flow are causing the distribution to be the shape they are?What do the results say about the size of the wake compared to the size of the cylinder? Figure [ 23 ] Figure [ 24 ] Figure [ 25 ] The vortices i n the flow cause turbulence to occur behind the cylinder which causes the distributions to change. It can be seen from figure 23 that the velocity changes instantaneously as you move away from the centreline, it can also be observed that from 45mm away and more the velocity start to become more uniform and fluctuate around the free stream velocity. From figure 25 and 25 from 45mm and onwards the RMS and RTI decrease.From the above graphs it can be deduced that the size of the wake is 45mm from the centreline or a total width of 90mm, which is 6 times the diameter of the cylinder. 12) What are the major sources of error likely to be in this experiment? Try and give a numerical estimate to the possible error(s) in the data. Some of the likely sources of error that may occur during this experiment are the calibration process as the hotwire was only calibrated at the centreline and as the hotwire was lowered using screw mechanism which it not totally accurate, there was no calibration o f the at the new position.Another source of error can be due to pressure fluctuations, and due to the velocity being measured using the pressure differences, these fluctuation can cause the velocity to vary. Another source of error could be the assumption of the flow being 2-d as turbulence is a 3-d. To calculate the error, I used the measured velocity table and the theoretical linear calibration velocity. Taking the average error, the percentage error in the experimental data was 5. 8%.

Figure [ 5 ] Figure [ 6 ] Figure [ 7 ] Figure [ 8 ] From the above graphs it can be seen that the worse extrapolated data is found using the quartic calibration and the best extrapolated data can be found using the linear calibration of A([V-Vo]^2)^n.Also higher order polynomial extrapolation can produce invalid values and as a result the error will magnify as high order of polynomials are used, so therefore the linear relationship is recommended. 6) In a fast Fourier transform (FFT) the data in the time domain is converted to the equivalent data in the frequency domain. The original data can therefore be considered as the sum of a series of sine waves of regularly spaced frequencies, with different magnitudes and phases. How is the frequency interval in the FFT determined? How can the frequ ency interval in an FFT be reduced?What impact could this have on an experiment? The frequency interval can be obtained by dividing the sampling rate by the number of samples used. For 660Hz the number of samples is 1024, so therefore the frequency interval is 660/1024 = 0. 6445. The frequency intervals can be reduced by increasing the number of samples used; this is advantageous as it gives a more accurate representation of the original signal. 7) Considering the FFT data, what can be done in an experiment to isolate genuine signals from random fluctuations in the data? Give an example of this in graphical form.Figure [ 9 ] Figure [ 10 ] From figure 9 it can be seen that the peak is unobtainable as the data is very noisy which could be due to disturbances. However this can be overcome by averaging the FFT which allows us to easily identify peaks which can be seen from figure 10. 8) In this experiment, why are 2 frequency peaks seen on the FFT when the hotwire is near the centre lin e? 2 frequency peaks can be seen on the FFT at the centreline due to the 2 vortices induced by the cylinder but as you move away from the centre line only one of the vortices is predominant.The two peaks occur at 129Hz and 250Hz. 9) With increasing distance from the centreline, how does the FFT distribution change? Include graphs to illustrate this for various locations across the wake. From the below figures it can be seen that as you move away from the centre line the peaks in the FFT distribution disappear. Figure [ 11 ] Figure [ 12 ] Figure [ 13 ] Figure [ 14 ] Figure [ 15 ] Figure [ 16 ] 10) Plot the probability distribution histograms of velocity for various positions across the wake.What does the histogram show and how can the variation in the histograms be explained in terms of the properties of the flow? Figure [ 17 ] Figure [ 18 ] Figure [ 19 ] Figure [ 20 ] Figure [ 21 ] Figure [ 22 ] By comparing the above probability distribution figures it can be seen that with distanc e away from the centreline the flow velocity develops a more uniform velocity. It can be seen that within the 40mm distance away from the centreline, the probability distribution of the velocity produces wide distribution of velocities; this is due to the various velocities inside the wake and turbulence.For distance more than 40mm away the probability distribution of velocity becomes more uniform, which implies the vortices play no role in affecting the flow at these distances away from the centreline. It can also be seen that the flow speed at these distances increases as the flow diverges and accelerates around the cylinder. 11) Plot a graph showing the variation of mean velocity, RMS velocity and turbulence intensity with distance across the wake. What physical phenomena in the flow are causing the distribution to be the shape they are?What do the results say about the size of the wake compared to the size of the cylinder? Figure [ 23 ] Figure [ 24 ] Figure [ 25 ] The vortices i n the flow cause turbulence to occur behind the cylinder which causes the distributions to change. It can be seen from figure 23 that the velocity changes instantaneously as you move away from the centreline, it can also be observed that from 45mm away and more the velocity start to become more uniform and fluctuate around the free stream velocity. From figure 25 and 25 from 45mm and onwards the RMS and RTI decrease.From the above graphs it can be deduced that the size of the wake is 45mm from the centreline or a total width of 90mm, which is 6 times the diameter of the cylinder. 12) What are the major sources of error likely to be in this experiment? Try and give a numerical estimate to the possible error(s) in the data. Some of the likely sources of error that may occur during this experiment are the calibration process as the hotwire was only calibrated at the centreline and as the hotwire was lowered using screw mechanism which it not totally accurate, there was no calibration o f the at the new position.Another source of error can be due to pressure fluctuations, and due to the velocity being measured using the pressure differences, these fluctuation can cause the velocity to vary. Another source of error could be the assumption of the flow being 2-d as turbulence is a 3-d. To calculate the error, I used the measured velocity table and the theoretical linear calibration velocity. Taking the average error, the percentage error in the experimental data was 5. 8%. Within a range Can not measure supersonic velocities

Microsoft Internet Marketing Strategies and Competitive Advantage

Microsoft Internet Marketing Strategies and Competitive Advantage Introduction Internet technology inspired a business and commerce revolution not witnessed before. Once used for military purposes, internet communication nowadays provides an important platform for business to business, and business to customer interaction. Company websites have become primary tools where potential customers source for information on particular corporate products before making the actual purchase.Advertising We will write a custom research paper sample on Microsoft Internet Marketing Strategies and Competitive Advantage specifically for you for only $16.05 $11/page Learn More Besides, websites have become important cost-effective marketing platforms where businesses launch products and display crucial marketing information for the end users (Arnold, J. et al, 2011, p. 56). Despite the unmistakable advantage however, the rise of the internet and other online technologies have led to creation of security loopholes that, when maliciously explo ited, negatively exposes the concerned businesses (Garfinkel Spafford, 2002, p. 48). This discussion will focus on internet technology, marketing and security from the perspective of Microsoft, a leading US software development firm whose products like windows have become a household name. Specifically, the discussion will concentrate on description and evaluation of Microsoft’s website in terms of product information, corporate contact information, tailoring of products for customers based on their taste and provision of customer information at purchase. Additionally, there will be an analysis and evaluation of Microsoft’s privacy and security policies as well as the envisaged corporate response to a security breach. In this regard, there will be special emphasis on a security breach on the company’s website and system sometime on October this year, which caused a scare among customers and prompted a quick reaction from Microsoft’s security team. Furthe rmore, the discussion will tackle the company’s internet marketing strategies and the competitive advantage that its website offers. Finally, there will be recommendations on two tools that the author feels are necessary in the firm to ensure greater security for its customers.Advertising Looking for research paper on it? Let's see if we can help you! Get your first paper with 15% OFF Learn More Microsoft Website A corporate website is a business’s online window and a vital gateway to online business success (Catalano Smith, 2000, p. 118). While a â€Å"good† corporate website is relative, web content in any credible website must identify specific problems to which they extend solutions to customers as well as the important goals they help customers attain. Additionally, web content must establish credibility and also present a call to action that nudges the customer to take the next step in buying the product or service. In Microsoftâ⠂¬â„¢s case, the website home page conspicuously displays the tabs linking to product information. Though a bit cluttered, the respective pages provide a somewhat brief explanation of the products under software, business software and hardware and entertainment categories. The approach the company has undertaken in dispensing its product information is understandable given the large portfolio of the products they offer under every category. The layout through the product information arrangement in the pages displays a subtle acknowledgement of the size of the product portfolio hence the efforts to balance the information available. In a nutshell, Microsoft’s website offers precise product information that is necessary and enough to help a potential customer make an informed decision. On a face value, the company’s website has not given any special emphasis on the contact information. The website displays the â€Å"contact us† tab in the traditional way that is c haracteristic of most corporate and private websites. The â€Å"contact us† link however leads to a detailed page that offers e-mail, chat and telephone links through which to reach the company. The above three links further have sub links that easily enable a prospective customer to access the required information with more precision. It is necessary however, to enhance the â€Å"contact us† link on the home page in a way that enhances a â€Å"good† customer service perception.Advertising We will write a custom research paper sample on Microsoft Internet Marketing Strategies and Competitive Advantage specifically for you for only $16.05 $11/page Learn More There is a concerted effort to develop products to the specific needs of customers. Given the dynamic and varying nature of corporate needs, Microsoft’s website has done well in expounding the basic meaning of products, where they suit and where they best fit. One of the stren gths the website displays concerning customization of products for customers is avoidance of blanket statements that tend to lure customers with the belief that the company can sort their software problems â€Å"no matter what they are†. Microsoft’s website lacks an online portal that will enable customers place online orders, perhaps due to the complexity and specificity of the company’s products. It is apparent that the company relies on the contact information â€Å"further assistance† and possibly for provision of customer information on purchase. As a result, there is an acute lack of customer purchase information in the website. Despite the links however, it is a strategic failure for the website not to avail such information even in the most general terms. Microsoft Internet Marketing Strategies and Competitive Advantage Initially, Microsoft’s resources and innovation helped it to enjoy some sort of monopoly status in internet and software d evelopment market. However, the company nowadays is facing stiff completion from counterfeits and other rising companies such as Google and Apple (Boone Kurtz, 2011, p. 175). The company has in place a marketing strategy that places emphasis on internet marketing. Some of the internet strategies include, collaboration with social networking sites especially aimed at promoting its search engine Bing, placing ads in rival search engines and promoting offers through their main website (Beyazitoglu, 2010, p. 98). While the above strategies are likely to pay dividends, they are part of the traditional internet marketing strategies whose effectiveness is likely to face limitation. However, social networking sites are yet to give their full potential in terms of marketing, hence it is a smart strategy which the company needs to improve and concentrate on in order to stay competitive.Advertising Looking for research paper on it? Let's see if we can help you! Get your first paper with 15% OFF Learn More According to McDaniel Gitman (2008, p. 108), competitive advantage is largely based on a company’s ability to outdo competitors by doing what they do better or by doing it in a completely different way. While Microsoft’s website is up to date, it offers little competitive advantage compared to its rivals. The only competitive advantage perhaps the website provides is the fact that is offers the company’s flagship products like Windows which have almost become a necessity for all computer users. Privacy/ Security Policy and Response to Security Breach In the backdrop of increased corporate espionage, web security has become a top priority in many organizations (Mackey, 2003, p. 78). Microsoft has an elaborate privacy policy that clearly stipulates the kind of information the company collects from the website and what it uses it for. According to the policy, the company clarifies that it collects personal information with a customer’s consent, explains the uses of the personal information, gives information on how to contact it in case of any issue regarding privacy and also highlights on a customer’s choices and options concerning promotional communication from the company. Generally, the policy is comprehensive and addresses most of the concerns an average Microsoft website users would be interested in regarding privacy. It is important to note that Microsoft has one of the most elaborate cyber security systems in the corporate world (Ratliff Ballard, 2006, p. 24). Despite assurance of security of personal information in the website, an attack on the website in October this year cast doubt on the company’s ability to detect and repulse hackers out to siphon information. In the attack, hackers remotely transferred source codes from the Microsoft website by sending passwords to an external e-mail account in Russia. The attack that according to the company lasted for 12 days used the QAZ Trojan malware which gained acce ss to the company system through an employee e-mail. It is possible that Microsoft did not secure their network’s access points effectively exposing their remote access system that resulted in security breakdown. The company’s response to the breach included invitation of FBI Computer Analysis Response Team that examined the company’s PC’s and including a review of network logs whose sole aim was to detect traceable fingerprints of the intruder. Additionally, Microsoft blocked and in some cases limited access of some of its employees to its network outside their office. By this action, Microsoft prevented a return of any hacker to its network. Security Recommendations In light of the above security breach it is important that the company beefs up its virus scanning/protection as well as network access point protection. The above attack may have happened due to a breakdown of virus and access point protection systems. Logging systems also have become some of the most vulnerable security points in any network system (Bhasin, 2003, p. 67). It is also important that the company disables unused ports besides initiating close monitoring of the logging system. Conclusion Given its ability to help businesses slash costs like in the case of Dell, the internet’s potential in business and commerce is yet to reach its epitome. Besides e-commerce, there are still more innovative applications that corporations are yet to exploit. Growing global access to the internet, especially by previously unreached populations especially in Africa, Asia, and Eastern Europe offer a great marketing opportunity. However, the threat from illegal intrusion is also growing by the day. It is therefore prudent for corporations to invest in secure internet technologies through research and development in order to ensure safe internet transactions, while guarding against data theft.

Ethics, Values, and Career Success

Ethics, Values, and Career Success One of the most important personal successes in society is career success. A person's values and later his ethics are the building blocks of a successful career. Achieving career success leads to a higher level of personal fulfillment. Understanding one's values can help to choose a career path that is conducive to his development as a person. Values are usually the result of acceptable cultural behavior and learned behavior from families. Values tend to lead to goals and ethics help a person to reach those goals.People hold certain beliefs concerning the aspects of work. These beliefs show how people should conduct themselves and what type of challenges the work environment will offer to them. Work values include several general categories. These include extrinsic or instrumental values, intrinsic and cognitive values, relational or social values, and power or self-enhancement values (Ravlin, 2007). Values, defined by businessdictionary.com, are important or endearing beliefs shared by members of a culture about what is good or desirable and what is not.Work values will differ based on a culture from a certain region or nation. Work values influence perceptions of people in a work environment when contexts are not clearly defined. Values also influence behavioral decisions. Values also lead to goals, which lead to certain behaviors. Certain values play more important roles in influencing particular behavior. "For example, dominant honesty value produces more ethical decisions" (Ravlin, 2007, p. 909). The relationship between work values and behavior play sometimes small roles and other times larger roles depending on the situation. Work value similarities generate a more productive work environment and positive attitudes. Values are the building blocks for ethics (Work Values, 2007).Values and ethics are both very important in careers and professional environments. Ethics as defined by Merriam-Webster's Third New International Dictionary Unabridged...

Physics Fields and Disciplines of Study

Physics Fields and Disciplines of Study Physics is the branch of science which is concerned with the nature and properties of non-living matter and energy that are not dealt with by chemistry or biology, and the fundamental laws of the material universe.  As such, it is a huge and diverse area of study. In order to make sense of it, scientists have focused their attention on one or two smaller areas of the discipline. This allows them to become experts in that narrow field, without getting bogged down in the sheer volume of knowledge that exists regarding the natural world. The Fields of Physics Physics is sometimes broken into two broad categories, based on the history of the science: Classical Physics, which includes studies that arose from the Renaissance to the beginning of the 20th century; and Modern Physics, which includes those studies which have been begun since that period. Part of the division might be considered scale: modern physics focuses on tinier particles, more precise measurements, and broader laws that affect how we continue to study and understand the way the world works. Another way to divide physics is applied or experimental physics (basically, the practical uses of materials) versus theoretical physics (the building of overarching laws as to how the universe works). As you read through the different forms of physics, it should become obvious that there is some overlap. For example, the difference between astronomy, astrophysics, and cosmology can be virtually meaningless at times. To everyone, that is, except the astronomers, astrophysicists, and cosmologists, who can take the distinctions very seriously. Classical Physics Before the turn of the 19th century, physics concentrated on the study of mechanics, light, sound and wave motion, heat and thermodynamics, and electromagnetism. Classical physics fields that were studied before 1900 (and continue to develop and be taught today) include: Acoustics: The study of sound and sound waves. In this field, you study mechanical waves in gases, liquids, and solids. Acoustics includes applications for seismic waves, shock and vibration, noise, music, communication, hearing, underwater sound, and atmospheric sound. In this way, it encompasses earth sciences, life sciences, engineering, and the arts.Astronomy: The study of space, including the planets, stars, galaxies, deep space, and the universe. Astronomy is one of the oldest sciences, using mathematics, physics, and chemistry to understand everything outside of the Earths atmosphere.Chemical Physics: The study of physics in chemical systems. Chemical physics focuses on using physics to understand complex phenomena at a variety of scales from the molecule to a biological system. Topics include the study of nano-structures or chemical reaction dynamics.Computational Physics: The application of numerical methods to solve physical problems for which a quantitative theory already exists. Electromagnetism: The study of electrical and magnetic fields, which are two aspects of the same phenomenon.Electronics: The study of the flow of electrons, generally in a circuit.Fluid Dynamics / Fluid Mechanics: The study of the physical properties of fluids, specifically defined in this case to be liquids and gases.Geophysics: The study of the physical properties of the Earth.Mathematical Physics: Applying mathematically rigorous methods to solving problems within physics.Mechanics: The study of the motion of bodies in a frame of reference.Meteorology / Weather Physics: The physics of the weather.Optics / Light Physics: The study of the physical properties of light.Statistical Mechanics: The study of large systems by statistically expanding the knowledge of smaller systems.Thermodynamics: The physics of heat. Modern Physics Modern physics embraces the atom and its component parts, relativity and the interaction of high speeds, cosmology and space exploration, and mesoscopic physics, those pieces of the universe that fall in size between nanometers and micrometers. Some of the fields in modern physics are: Astrophysics: The study of the physical properties of objects in space. Today, astrophysics is often used interchangeably with astronomy and many astronomers have physics degrees.Atomic Physics: The study of atoms, specifically the electron properties of the atom, as distinct from nuclear physics which considers the nucleus alone. In practice, research groups usually study atomic, molecular, and optical physics.Biophysics: The study of physics in living systems  at all levels, from individual cells and microbes to animals, plants, and entire ecosystems. Biophysics overlaps with biochemistry, nanotechnology, and bio-engineering, such as the derivation of the structure of DNA from X-ray crystallography. Topics can include bio-electronics, nano-medicine, quantum biology, structural biology, enzyme kinetics, electrical conduction in neurons, radiology, and microscopy.Chaos: The study of systems with a strong sensitivity to initial conditions, so a slight change at the beginning quickly become major changes in the system. Chaos theory is an element of quantum physics and useful in celestial mechanics. Cosmology: The study of the universe as a whole, including its origins and evolution, including the Big Bang and how the universe will continue to change.Cryophysics / Cryogenics /Low-Temperature Physics: The study of physical properties in low-temperature situations, far below the freezing point of water.Crystallography: The study of crystals and crystalline structures.High Energy Physics: The study of physics in extremely high energy systems, generally within particle physics.High-Pressure Physics: The study of physics in extremely high-pressure systems, generally related to fluid dynamics.Laser Physics: The study of the physical properties of lasers.Molecular Physics: The study of the physical properties of molecules.Nanotechnology: the science of building circuits and machines from single molecules and atoms.Nuclear Physics: The study of the physical properties of the atomic nucleus.Particle Physics: The study of fundamental particles and the forces of their interaction.Plasma Ph ysics: The study of matter in the plasma phase. Quantum Electrodynamics: The study of how electrons and photons interact at the quantum mechanical level.Quantum Mechanics / Quantum Physics: The study of science where the smallest discrete values, or quanta, of matter and energy become relevant.Quantum Optics: The application of quantum physics to light.Quantum Field Theory: The application of quantum physics to fields, including the fundamental forces of the universe.Quantum Gravity: The application of quantum physics to gravity and unification of gravity with the other fundamental particle interactions.Relativity: The study of systems displaying the properties of Einsteins theory of relativity, which generally involves moving at speeds very close to the speed of light.String Theory / Superstring Theory: The study of the theory that all fundamental particles are vibrations of one-dimensional strings of energy, in a higher-dimensional universe.

Database Design and Implementation Assignment Example | Topics and Well Written Essays - 5000 words

Database Design and Implementation - Assignment Example A major downside of this site is that it is very slow. The seller is not required to pay any fee for posting an item for sale. The sites has strong measures and applications installed that ensures that it is fraud proof and the sellers can list as many items as they want as opposed to most online purchasing sites. E-bay is one of the leading online shopping market place where buyers and sellers transact a wide variety of goods and services worldwide. It has become a multi-billion dollar company after it was founded back in 1995. It has included buy-it-now as a standard shopping, an expansion from its original auction format. A number of items, from cars to antiques, are listed by a seller who then chooses to only accept bids for the item thus enabling the buyer to purchase the item immediately. The first buyer eager to pay the sellers stated price gets the item on a buy-it-now option. All the three sites have five major entities that is; the auction, product, payment, seller and the buyer. Of the four entities only three are actively involved at any given time, mostly, the auction, product and the buyer. The three entities have major common attributes across the three sites most of which were identified as the generic attributes. The product id, seller/.buyer id and the product id alongside other attributes formed the major attributes across the three sites. The other attributes that were rejected were either irrelevant or less important and could be retrieved through the major attributes such as the auction, seller/buyer or product ids. Normalizing the possible tables consisting of the entities alongside their attributes led to the rejection or dropping off of some attributes to avoid data redundancy. The product name, product description, product prices and product image from the auction table can be compressed into a different table named product with a primary key being product id. The auction table therefore will be normalized

Impact of TESOL Continuing Professional Development programs (CPDs) Research Paper

Impact of TESOL Continuing Professional Development programs (CPDs) - Research Paper Example Impact of TESOL Continuing Professional Development programs (CPDs) Therefore, despite the numerous continues development programs available, the success of such programmes are measured by how best such trainees are able to transfer knowledge gained to their respective duties, skills improvement, in addition to job performance. Due to developments in information technology, there are increasing perceptions that ICT has resulted in major improvements in education, and may transform the learning process when implemented effectively (Oblinger & Oblinger, 2005). However, there are still arguments that discussions on ICT improving education are far-fetched, and that ICT has not always resulted to outright improvement of such programs (Smeets, 2005). Therefore, effectiveness of such teachers training programs related to ICT and other platforms have resulted in different findings depending on how such learning programs are implemented in different learning environments. This paper examines the challenges and impact of various professional training programs on both teachers and students. The article investigates several research papers on professional training programs, and outlines various findings to make a general summary regarding the impact of such programs. Short in-service teacher training (INSET) courses are one way in which the skills and knowledge of teachers may be revitalized through enhancing their skills and knowledge on specific aspects.... INSET courses are aimed at facilitating and stimulating new ideas in teachers and as a platform for teachers to meet and share with new colleagues their experiences and skills. However, the impact of the INSET courses according to Lamb may not be effectively realized without proper follow up of the participants. The motivation and stimulus gained by teachers is fast eroded and teachers are frustrated when trying to implement all newly learned ideas; teachers enroll in such professional development courses to learn new ideas, but have difficulties applying the learned concepts and ideas in a static learning system, which does not encourage or facilitate them to apply such ideas (Lamb, 2005). This brings about tensions and frustrations in teachers. However, Bridges (2007) in a controlled group trial on the effectiveness of INSET reports the group actually registered impressive growth in skills, though on what the researcher termed as cautious positive results in an intensive immersion INSET. A study on Tanzania primary teachers on INSET programs showed that such INSET trained teachers were much better in introducing and developing lessons, in addition to involving students in class group work, which was found to improve learning (Hardman & Dachi, 2012). However, in another study, Bridges (2007) asserted that multiple assessments resulted in a lower self-reporting as the participants did not have enough time to express their concerns in the learning process. Despite this, INSET was found to have a varied degree of positive growth in knowledge acquisition. This reveals that measurement of the programme’s success in this case has to be based on enough feedback from such teachers, and how best class lessons improve. One way to measure the success of INSET programme in

Compare and contrast the fixed and flexible budgets Assignment

Compare and contrast the fixed and flexible budgets - Assignment Example However, in unstable business scenario, flexible budget is always more relevant as it helps the business to effectively manage possible changes in the business environment, which would be hazardous if not well managed. Therefore, budget managers are usually faced with the task of adopting the right type of budget for their organisations depending on business situation. This paper explores fixed and flexible budgets, their differences, preparation procedures and functions. A fixed budget (static budget), is a type of budget that remains unchanged over the budget period regardless of changes in the level of activity of the organisation. A fixed budget is â€Å"prepared of for one level of activity for a definite time period† (Dutta 2004 p. 25). On the contrary, a flexible budget is a budget which is designed to change with changes in activity level. It is also referred to as variable budget because it takes into account cost behaviour, such as fixed and variable costs, in connection with changes in output level or turnover (Weygandt, Kieso & Kimmel 2010). A fixed budget remains constant relative to the variation in the actual level of activity attained. This makes it inflexible. On the other hand, a flexible budget changes with the variation in the level of actual activity, which makes it flexible (Tulsian & Tulsian 2005). A fixed budget is developed based on one level of activity and relies on the assumption that no change will occur in the prevailing circumstances, which is impractical. On the other hand, a flexible budget is based on various levels of activity (Weygandt, Kieso & Kimmel 2010). In a fixed budget, all costs are related to a single level of activity. As such, variance analysis fails to provide valuable information about cost differences. On contrary, flexible budget analyses each cost on the ground of cost behaviour and thus gives important information about cost variances (Tulsian & Tulsian 2005). Under fixed budgets, the comparison of

Nanotechnology and water purification Essay Example | Topics and Well Written Essays - 3500 words

Nanotechnology and water purification - Essay Example It has been proved that contaminated water is the worldwide cause of death and is responsible for different complex diseases to have affected mankind as well as plants and other marine animals. Industries too, are facing major obstacles in the path of advancement, because of this problem. Water is the elixir of life without which any living creature cannot survive. The problem is that since it is so vital to mankind, human beings are unable to stop using water whether it is for drinking or external uses. There is no substitute for water and all countries ranging from the developed Western countries like the UK, USA or Germany to developing nations like India, Brazil, China and under-developed countries like South America and Africa, are facing this major problem of water pollution. Water is the main element for survival for every living being and so, paradoxically, it is also where bacteria and germs thrive and water becomes the breeding ground for new germs which are capable of killing humans and other animals. The Industrial revolution which made things easier for mankind is also responsible for water pollution. Ironically, it is the increased levels of contaminated water which are also creating havoc for these very industries whose existence in the first place gave rise to water pollution. But, no steps are being taken to curb this menace. To safeguard itself from the devastating effects of contaminated water, mankind came up with different ways to purify water so that it could be 100percent pure and germ-free. Human beings began by simply boiling water because the process of boiling water sterilizes it so that it becomes germ-free and fit for human consumption. Then they discovered that chlorine and iodine could also be used for purifying water but it was found to be leaving a strange after-taste. At last, they started purifying water by using the process of osmosis and reverse osmosis. (Meyer,

Indigenous Australian and Diabetes Essay Example | Topics and Well Written Essays - 3500 words

Indigenous Australian and Diabetes - Essay Example As such, Aborigines health is very poor compared to other Australians. Statistics indicate that only about forty percent of Aborigines are in good health compared to more than 80% of other Australians. This affects the mortality rate of these people, which is more than two times the non-indigenous Australians. Poor healthcare to Aborigines and their lifestyles increase chances of getting chronic diseases like diabetes. Diabetes is one of the diseases that has increased Aborigine mortality rate in the recent years. There are few clinics and healthcare centers in regions where aborigines live and their diet is also poor. At the same time, many cannot afford medication. More than 30% of the entire Aborigine population has diabetes. In addition, the government has been doing little to Aborigine health. Less than one percent of the national budget was used on Aborigine health. This is little money and may not have a high impact on the Aborigine health. Health experts and civil rights have lobbied the government to invest more in Aborigine healthcare. This paper will discuss Australian Indigenous Health, specifically diabetes, the current trends, why Aborigines are affected more than Non-Aboriginal Australians, strategies used to mitigate Diabetes and what can be done to improve the current intervention measures and strategies. Epidemiology Diabetes is one of the most common chronic conditions in the world today. The disease is as a result of low production of insulin which is responsible for regulating blood sugar in the body. Diabetes is characterized by high levels of blood sugar and can adversely affect the general health of the patient. The condition makes the body weak making the patient susceptible to opportunistic conditions, which can even lead to death. There are two common types of Diabetes, Type 1 and Type 2. Type 1 diabetes is caused an autoimmune disease of the beta cells of the pancreas. These cells are responsible for the production of insulin, which regulates blood sugar. Type 1 diabetes is most common in young people and accounts for 5 to 10% of the total diabetes patients. Type 2 diabetes is caused by health factors that have suppressing factors on the pancreas. Excess fats make it almost impossible for the beta cells to produce insulin and regulate body sugar. In fact, more than 75% of people having type 2 diabetes are either overweight or obese. Type 2 is common in adults and accounts for 90 to 95% of all diabetic patients (Hawley and Dunstan, 2008). There is no cure for either of the two types of diabetes, but research and experiments are underway to find a cure. Currently, diabetes is management is done to mitigate the risks that are associated these conditions for example (Thomas and Nestel, 2007). Type 1 diabetes patients have to live on insulin shots. They inject insulin on their hands every day according to the physician instructions. Type 2 diabetes patients are advised to exercise to lose weight and cut fats in the body. They can also use pills if the former strategy does not work. Diabetes patients have to eat healthy and exercise often to mitigate the effects of the condition (Speight, 2013). Prevalence of diabetes in Australia is relatively high, currently ranked the fifth country. Diabetes is common among the elderly people. There is a higher prevalence of diabetes to Aborigines in Australia compared to non-Aborigines. According to Australian Institute of Health and Welfare,

The main reason for children committing crimes is the domestic violence. Another reason is hardcore video games and movies containing this sort of acts. According to some voluntary organizations dedicated to drug and alcohol de-addiction, in the last few years' lots of youngsters have started approaching them. They also say that drug addicts start taking drugs at 13 or 14, but only come to the rehab centers when the situation becomes grim or out of control. This is because they start taking drugs recreationally and by the time they start having problems and decide to seek help it takes time. Unlike social drinking which doesn't affect one's lifestyle, there is nothing like social drugs because substances like cocaine and heroin are very addictive and illegal. The problem arises because most youngsters believe they won't get addicted not realizing that with drugs like cocaine and heroin it's very easy o get hooked on. And when they get addicted the trouble starts to unfold and slowly indulging in criminal offences comes into the picture. Independent courts act separate from other courts and are found in Connecticut Rhode Island and Utah. States like Alabama doesn't have independent and separate courts.

Indigenous Australian and Diabetes Essay Example | Topics and Well Written Essays - 3500 words

Indigenous Australian and Diabetes - Essay Example As such, Aborigines health is very poor compared to other Australians. Statistics indicate that only about forty percent of Aborigines are in good health compared to more than 80% of other Australians. This affects the mortality rate of these people, which is more than two times the non-indigenous Australians. Poor healthcare to Aborigines and their lifestyles increase chances of getting chronic diseases like diabetes. Diabetes is one of the diseases that has increased Aborigine mortality rate in the recent years. There are few clinics and healthcare centers in regions where aborigines live and their diet is also poor. At the same time, many cannot afford medication. More than 30% of the entire Aborigine population has diabetes. In addition, the government has been doing little to Aborigine health. Less than one percent of the national budget was used on Aborigine health. This is little money and may not have a high impact on the Aborigine health. Health experts and civil rights have lobbied the government to invest more in Aborigine healthcare. This paper will discuss Australian Indigenous Health, specifically diabetes, the current trends, why Aborigines are affected more than Non-Aboriginal Australians, strategies used to mitigate Diabetes and what can be done to improve the current intervention measures and strategies. Epidemiology Diabetes is one of the most common chronic conditions in the world today. The disease is as a result of low production of insulin which is responsible for regulating blood sugar in the body. Diabetes is characterized by high levels of blood sugar and can adversely affect the general health of the patient.

Eczema Nursing Presentation PowerPoint Example | Topics and Well Written Essays - 1750 words

Eczema Nursing - PowerPoint Presentation Example With relation to the differential diagnosis, a range of conditions need to be differentiated including psoriasis, fungal infections, scabies, scarlet fever, pityriasis rosea, measles, tinea corporis and squamous cell carcinoma. Introduction/Definition Eczema or dermatitis is a disorder in which the skin is inflamed (especially epidermis) along with the development of vesiculation sometimes in acute phases. It has been derived from the Greek word meaning to ‘boil out’, and hence medical practitioners consider it to look like the skin is boiling out. The condition is usually acute in nature, but can be a chronic inflammatory disorder of the skin causing pruritius, redness, vesiculation, which finally become encrusted, hemorrhagic, thickened and scales off (Vorvick, 2009). Some of the common types include:- Allergic contact eczema – Following contact with a foreign substance such as a poison, lotion, etc, there is a local allergic reaction Atopic dermatitis – It is a chronic inflammatory skin disorder and often accompanied with other disorders such as asthma and hay fever. It is commonly seen on the arms and at the back of the knees, and flare up periodically Contact eczema – the reaction is localised when a allergen is contact causing itching, redness and swelling Seborrheic eczema- Commonly called as dandruff and is a mild skin inflammatory disorder arising due to unknown reasons and causing scaling, redness and itching of the scalp and face Neurodermatitis – This is characterised by scratching or picking of the skin resulting in development of rashes Stasis dermatitis – Develops from congestion of the veins of the legs resulting in irritation of the overlying skin Dyshidrotic eczema – Commonly occurs on the palms and soles and is seen as deep-seated skin lesions Perioral eczema – Bumpy rash and ulcers that develop around the mouth Nummular eczema – This is a coin-shaped lesion that develops in an irritated portion of the skin causing scaling, itching and encrusting (MedicineNet, 2011). Pathophysiology The exact cause of eczema and dermatitis is still not clearly known, but it may be a result of interplay of host, genetic and environmental factors. Further, stress and various emotional disorders can worsen or exacerbate the condition especially atopic dermatitis (Mayo Clinic, 2011). Most of the eczema occurs due to a hypersensitivity reaction of the skin, causing chronic skin inflammation (Lehrer, 2009). Some of the eczemas are autoimmune conditions and some of them are genetically transmitted, running in families. Atopic dermatitis is known to be transmitted through a genetic route and is often associated with asthma and hay fever. However, this association is often being questioned, as not all individuals with atopic dermatitis have asthma and hay ever, and not all individuals with asthma and hay fever have atopic dermatitis. However, both these conditions tend to run i n families, and this may be due to common genetic trait being carried on (Mayo Clinic, 2011). Such disorder appears on trivial inflammation of the skin. Allergic eczemas are usually common and the individual may also have other allergic conditions such as asthma, hay fever, etc (DIS, 2011). There are several exacerbating factors for

Zora Neale Hurston Essay -- Zora Neale Hurston

  Ã‚  Ã‚  Ã‚  Ã‚  Throughout the history of our great nation, we have been blessed with many great writers those black and white. Some of these writers have left profoundly inspirational impressions on our lives, touching us in a way that will never be forgotten. During the â€Å" â€Å"Roaring 20’s,† many new aspects of life were introduced to American society, forever changing our lives. Along with the â€Å"Roaring 20’s,† came the Harlem Renaissance, a cultural movement during which black art, literature, and music received much deserved credit. It originated in New York City's Harlem district and was also called the Black Renaissance, or New Negro Movement. It was quite common in African-American society for people to exchange tales and folklores that stemmed as far back as their ancestor’s days in Africa. One of the most accomplished writers of this time was a beautiful, young and extremely intelligent woman. This young woman took this comm on practice and used them in her novels and tales. It was this simple yet intriguing idea for writing stories that helped launch Zora into the forefront of the Harlem Renaissance. Regardless, of her trying and discouraging lifestyle as a child, Zora chose to press onward and upward throughout her life. Zora had more than her fair share of hardships from her early childhood up until her last days on this earth. Though tough times were all too frequent, Zora continuously worked tirelessly towards her destiny. In her lifetime she was acknowledged as a leading force for the Harlem Renaissance, forever revolutionizing America’s views of African-American’s as well as the great intelligence and creative capability of women. Through her short stories, poems, and novels Zora was able to reach many people nation wide and therefore further express her views and beliefs to those black and white.   Ã‚  Ã‚  Ã‚  Ã‚  On January 7, 1891 in Notasulga, Alabama Lucy Ann Potts Hurston gave birth to the sixth of her eight children. This child was given the name Zora or â€Å"light of dawn,† little did her parents know, she would certainly live up to her meaningful name. Lucy Ann Potts Hurston was an elementary school teacher until she later married John Hurston, a mulatto pastor of Zion Hope Baptist Church and the Macedonia Baptist church, farmer, carpenter and later Mayor of Eatonville of 1897 serving three terms.

In this article she stated that she believed that black children and white children should not attend the same schools.   Ã‚  Ã‚  Ã‚  Ã‚  Zora went on writing many publications that separated her from blacks; she was marked as a traitor. For this reason she spent her last days alone and in poverty working as a domestic until falling ill and dying of a stroke in 1960. However controversial, Zora will be remembered for her great contributions to the Harlem Renaissance and fine literary works. She has been a very influential and a true inspirational figure to many writers of today. One that comes to mind is a local playwright by the name of Mari Evans, who recently did a rendition of Hurston’s novel Their Eyes Were Watching God, titled â€Å"Eyes† Zora had a different outlook on life than most African Americans of her time but has remained the cornerstone of the Harlem Renaissance making black culture known and felt by all. That is why Zora will remain an outstanding and successful pillar in the literary world for many years to come.

Importance of Value Based Education Essay

In the present era of education assisted by ultramodern technology, we are inclined more towards knowledge and ranks in the examination than application of learning in our day-to-day life. Theodore Roosevelt warns, â€Å"To educate a man in mind and not in morals is to educate a menace to society.† It is a lamentable fact that in the prevalent scenario of education, the majority of the teachers as well as the taught have turned into grades-oriented and marks-oriented individuals overlooking and undermining the superlative purpose of education i.e. refinement of ethics, purification of soul ad enlightenment of human intellect. More sadly, in the pursuit of degree-oriented education, we have, wittingly or unwittingly, failed to incorporate the learning of moral and ethical values to our studies for the positive nourishment of our character. â€Å"The degeneration in the present day life, the demoralization of public and private life and the utter disregard for values, are all t raceable to the fact that moral, religious and spiritual education has not been given due place in the educational system.† (Rena, Ravinder 2006) In a broader view, as the outcome of education, we are producing successful professionals obsessed with material pursuits, who fail as considerate, altruistic and humane people. Totally remiss of philanthropic and humanitarian element of their work, these professionals are content with the achievement of absolute luxury as well as authority as being the radical purpose of their studies. This kind of attitude is the result of the myopic and inadequate execution of the abilities of teachers and teacher-educators. Thereby, most of the existing students indulge themselves into anti-social and unethical dealings in their futures endeavours. â€Å"Unfortunately, education is becoming more or less materialistic and the value traditions are being slowly given up.† (Erwin, 1991) We, nonetheless, have time to redress our wrongs and set right our shortcomings. In this regard, the curriculum and teachers play a pivotal role. Curriculum must contain distinctive instructions for the values associated with each lesson. The teachers, on the other hand, must explain those values to the students and encourage them to put the same into practice in their daily life. In this way, we can surely bring about a positive change in the overall attitude of our students towards learning as well as society. Moreover, the students in the academic phase of their school life need to learn to be kind, compassionate and considerate towards their fellow beings. This could be communicated to them while teaching Islamiyat, Ethics, Pakistan Studies, Science, English or any other subject of their interest. In addition to teaching students the periodical and chronological record of life and achievements of the successful and influential people in the world, the teachers must highlight the brighter aspects of their character which dominated their practice and performance. The students should be inspired to identify the positive implications of their study in their everyday life. In this connection, value-based education can not only improve a person’s life but it can also advance society in the right direction. â€Å"So, value education is not simply the heart of education, but also the education of the heart. It is a necessary component of holistic citizenship education.† (Rena, Ravinder 2006) This practice can be carried out while teaching students the formation of water in Chemistry, the teacher must talk about the worth and use of water. The students can also be informed about the importance of growing plants and trees in our daily life in Botany. With reference to their lessons, the students could be enlightened to show reverence to their teachers and elders and love their younger ones. Value-based education can also be a source of appreciation and promotion of one’s own culture and history. More importantly, the students can probe into and find the eternal solace in Nature. In addition to that, they must praise the creations of Allah and love both the creatures and the Creator. Besides integrating values in the provided curricula, the value-based education can also be featured in the co-curricular and extra-curricular activities. The special assemblies and functions could be arranged to instill the vital importance of fair and descent values. This could also be combined with the regular activities in the sports ground and academic contests. Sir Frances Bacon in his essay ‘Of Studies’ says, â€Å"Histories make men wise; poets, witty; the mathematics, subtle; natural philosophy, deep; morals, grave; logic and rhetoric, able to contend.† Hence, if we want to achieve the purpose of education in life, fortify humane feelings, alleviate poverty, bring peace and prosperity to our country as an educated and civilized nation, we must develop the constructive thoughts and attributes in our children vis-à  -vis their academic and professional uplift to positively mould their character as an example for others to follow. The teachers must also inculcate the idea of ‘peaceful coexistence with people from other cultures and countries.’ (P.L Joshi 2007) Therefore, we should integrate information, knowledge, skills with values in education and help students come together to bind this world in a peaceful harmony.
