Do school vouchers improve the quality of education Research Paper

Do school vouchers improve the quality of education - Research Paper Example . Non-voucher education systems compel guardians who take their children to private schools to double taxation, since they still contribute to public schools funding. Generally, school vouchers are put in place to offset the cost incurred by families who choose to enroll their children to private schools that best fit their needs in a bid to improve their performance and quality of education (Altidor, 2005, p.15). School vouchers were first introduced with the aim of improving the quality of both the elementary and secondary school education with regards to Milton Friedman’s proposition in the 1950s. Parents and guardians seeking to provide high quality education for their children have contributed greatly to renewed interests in school vouchers. School voucher proposals seek to support households that choose to enroll their children in private schools through vouchers from the government to cover private school tuition costs either partly or fully. Arguments in support of the school voucher programs claim that through this program, households with are able to encourage educational systems competition that would go a long way in enhancing the quality of education that is being offered among the competing schools.Arguments in support of the school voucher place emphasis of aspects that suggests that students from low-income households who are enrolled in private schools have a higher probability of achieving higher performance levels on standardized tests unlike those in public schools.

DIWALI -THE FESTIVAL OF LIGHTS Essays -- essays research papers

Diwali rituals Diwali, the festival of lights, is one of the important and widely spread holidays celebrated in India. It is a celebration of lights, and for many, it is truly a sensory experience; some families decorate their houses with all sorts of lights and open up to the neighbors, sharing their love and their food. Those celebrating Diwali spend time with family and friends. They perform religious ceremonies to bring in wealth and prosperity for a new year, cook and eat delicious food, design rangolis, light up their lives by lighting diyas (small earthen lamps), candles and sometimes, by lighting fireworks. Diwali is celebrated in honor of the lord Rama, who on this day returned from a forest exile. Diwali is actually the middle day in a five-day festival that rings in the Hindu New Year. For Diwali, I go to festivals and hold pooja at my house The five days of Diwali Diwali is the most important festival celebrated in India. Diwali or Deepawali means an array of lights. It is a festival of lights symbolizing victory of good over evil and the glory of light. Diwali is celebrated as the day that Lord Rama returned to Ayoda after defeating Ravana. Diwali also signifies Harvest Festival. Another legend is Naraksura, a monster who was a troublemaker to the gods. Lord Krishna and Satyabama killed the demon. Diwali is celebrated in five days. The first day of Diwali is called Dhanteras. The second day is called Narak Chatardasi. On this day Lord Krishna destroye...

Exercise and Healthy Diet for Obesity

Exercise and Healthy Diet for Obesity Obesity is a medical condition that requires long term treatment and intervention in which a regular exercise and healthy diet are probably the most believable two important treatments that could help altering the clinical course of obesity. First of all, exercising on a regular basis is believed to be one of the two most essential factors helping you to get a better health condition. This is because exercising is a process of using the amount of energy from the fat stored in your body.There are many types of exercise in which different modes of exercise produce different physiological responses. However, in my opinion, I think that the most effective type of exercise would be aerobic exercise such as jogging, running, cycling, and swimming. Aerobic exercise most requires you to extensively work out on your large muscles group which particularly includes your leg and core muscles. Moreover, this mode of exercise should take between 30 to 60 minut es and 3 to 5 days per week.As you are exercising, your maximum heart rate intensity should be between 55 to 65 percent of your maximum heart rate, recommended for weight loss. Nonetheless, all beginners should initially start their exercise with a low intensity as the beginners are easily at high risk of joints injury, if you do not begin at the low intensity. In addition to aerobic exercise, there is also another effective mode of exercise which is known as anaerobic exercise whereby weight training is the most common activity for anaerobic exercise.Weight training activity allows your particular muscles to work more and therefore gains more muscle mass. As your muscle mass increases, the rate of metabolism in your body increases as well. Therefore, it is better for you to work on both types of exercise including aerobic and anaerobic exercises as these two modes of exercise would give you a better result in losing your weight. Next, another powerful factor for weight loss besides a regular exercise is ‘a healthy diet’ in which this would effectively help you to lose weight as well.Healthy diet means low calories, low fat, high protein, and carbohydrate restriction in your daily food consumptions. Moreover, this simply means that to eat healthy is to pick fruits or vegetables for the week, plan a meatless day, prefer beans for protein, reduce fat from meats, eat more home cooking and snack with fruits. The power of healthy diet can help you to decrease your body fat more constantly and that would help you to better achieve weight loss.Hence, it is very important that you should refrain from eating sweets and fried food if it is not necessary and instead focusing more on the food with high protein and fibre. However, ‘fasting’ is strictly prohibited for healthy diet as each particular meal should include an adequate five food categories; which are carbohydrate, protein, fat, vitamin, and fibre. Fasting or dieting could cause you to b e starved and that would lead you to malnutrition, which is harmful to your health as your rate of metabolic and muscle mass would reduce rapidly.Metabolic rate of the body is reduced due to fasting or dieting is when your digestive system of your body does not work as well as it does and if when you return to your normal eating, there is a high of possibility for you to get Yo-Yo Effect that might cause you to even gain more weight in a short time. Last but not least, either regular exercise or healthy diet could essentially help you to alter the clinical course of obesity.As regular exercise would decrease your heart rate, blood pressure, cholesterol, body fat and also improve your muscle functions, which these can help the obesity to alter their clinical course. Hence, healthy diet also helps you to decrease your unwanted body fat and increase your rate of metabolism as well. Therefore, it is recommended for the obesity that you should both work on your regular exercise and eat h ealthy food as if you do them together, the more faster the more healthy of your body will become.

How to Make a Storm Glass to Predict the Weather

You may not feel the approach of impending storms, but the weather causes changes in the atmosphere that affect chemical reactions. You can use your command of chemistry to make a storm glass to help predict the weather. Storm Glass Materials 2.5 g potassium nitrate2.5 g ammonium chloride33 mL distilled water40 mL ethanol10 g natural camphor How to Make the Storm Glass Dissolve the potassium nitrate and ammonium chloride in the water.Dissolve the camphor in the ethanol.Add the potassium nitrate and ammonium chloride solution to the camphor solution. You may need to warm the solutions to get them to mix.Either place the mixture in a corked test tube or seal it within glass. To seal glass, apply heat to the top of the tube until it softens, and tilt the tube so the glass edges melt together. If you use a cork, wrap it with parafilm or coat it with wax to ensure a good seal. An advanced version of a cloud in a bottle, a properly prepared storm glass should contain colorless, transparent liquid that will cloud or form crystals or other structures in response to the external environment. However, impurities in the ingredients may result in a colored liquid. Its impossible to predict whether or not these impurities will prevent the storm glass from working. A slight tint (amber, for example) may not be cause for concern. If the solution is always cloudy, its likely the glass wont function as intended. How to Interpret the Storm Glass A storm glass may present the following appearance: Clear liquid: bright and clear weatherCloudy liquid: cloudy weather, perhaps with precipitationSmall dots in the liquid: potentially humid or foggy weatherCloudy liquid with small stars: thunderstorms or snow, depending on the temperatureLarge flakes scattered throughout the liquid: overcast skies, possibly with rain or snowCrystals at the bottom: frostThreads near the top: wind The best way to associate the appearance of the storm glass with the weather is to keep a log. Record your observations about the glass and the weather. In addition to the characteristics of the liquid (clear, cloudy, stars, threads, flakes, crystals, and the location of crystals), record as much data as possible about the weather. If possible, include temperature, barometer readings (pressure), and relative humidity. Over time, youll be able to predict the weather based on how your glass behaves. Keep in mind, a storm glass is more of a curiosity than a scientific instrument. Its better to allow the weather service to make predictions. How the Storm Glass Works The premise of the functioning of the storm glass is that temperature and pressure affect solubility, sometimes resulting in a clear liquid and other times causing precipitants to form. In similar barometers, the liquid level moves up or down a tube in response to atmospheric pressure. Sealed glasses are not exposed to the pressure changes that would account for much of the observed behavior. Some people have proposed that surface interactions between the glass wall of the barometer and the liquid contents account for the crystals. Explanations sometimes include effects of electricity or quantum tunneling across the glass. History of the Storm Glass This type of storm glass was used by Robert FitzRoy, the captain of the HMS Beagle during Charles Darwins voyage. FitzRoy acted as meteorologist and hydrologist for the journey. FitzRoy stated storm glasses had been made in England for at least a century before his 1863 publication of The Weather Book. He had started to study the glasses in 1825. FitzRoy described their properties and noted there was a wide variation in the functioning of the glasses, depending on the formula and method used to create them. The basic formula of the liquid of a good storm glass consisted of camphor, partially dissolved in alcohol; along with water; ethanol; and a bit of air space. FitzRoy emphasized the glass needed to be hermetically sealed, not open to the outside environment. Modern storm glasses are widely available as curiosities. The reader may expect variation in their appearance and function, as the formula for making the glass is as much an art as a science.
