based upon the favorable variance due to sales and the unfavorable variance due to operations. This net variance figure fails to highlight areas of deficiency to help identify corrective actions. Furthermore‚ this variance does not indicate the real cause of the favorable overall variance. The success and purpose of variance analysis is reliant on how quickly and effectively it is able to aid in undertaking corrective actions. In addition to the lack of outputs that could lead to decision-making

CAUSES OF DEFORESTATION Deforestation is the product of the interaction of the many environmental‚ social‚ economic‚ cultural‚ and political forces at work in any given region. The mix of these forces varies from decade to decade‚ and from country to country. As a consequence‚ generalizations are dangerous. In most cases‚ deforestation is a process that involves a competition amongst different land users for scarce resources‚ a process exacerbated by counter-productive policies and weak institutions

Causes of Crime In this modern era‚ many crimes keep happening around the world. A crime is the breaking of rules or law for which some governing authority can ultimately prescribe a conviction. Crimes that we usually find in newspaper are the disappearance of children‚ threats‚ kidnappings and many more. The causes of crime include poor parenting‚ failure education‚ media violence and poverty. One of the causes of crime is poor parenting. According to Currie and Tekin (April 2006)‚ maltreatment

Density of Solutions Lab Purpose: The purpose of this lab was to find out the densities of the known and unknown Solutions that were given to us. This can be found by dividing the mass by the volume of the Solutions. The other purpose of this lab was to perfect our skills in finding out the percentage error‚ uncertainties‚ random error‚ and systematic error. Variables: Independent: Mass Percentage of Solution (KCl); Unknown Solution; Temperature Dependent: Density Materials: 10.00 mL

This assignment must be submitted no later than November 22nd‚ 2011. 1. What is a true solution? Explain why the solute does not settle out of a solution. Is it possible to have one solid dissolved in another? Explain. In metals it would be called an alloy. 2. An aqueous solution of KCl is colorless‚ KMnO4 is purple‚ and K2Cr2O7 is orange. What color would you expect of an aqueous solution of Na2Cr2O7? Explain. Orange. 3. Explain why hexane will dissolve benzene but will not dissolve

been watered down‚ to complete this task a sample of commercial vinegar was tested twice using titration and an average was taken of the two samples to give a base line to compare the potentially tampered samples against. Introduction Vinegar is a solution made from the fermentation of ethanol (CH3CH2OH)‚ which in turn was previously fermented from sugar. The fermentation of ethanol results in the production of acetic acid (CH3COOH). The typical pH of vinegar ranges anywhere from 2 to 3.5‚ although

Refining Solutions Meghan L Adams PHL/458 July 16‚ 2013 David Boswell Refining Solutions There are a number of solutions that can be reviewed to solve most any problem and most require a touch of creative or critical thinking. William Hughes once said‚ “If we are not prepared to think for ourselves‚ and to make the effort to learn how to do this well‚ we will always be in danger of becoming slaves to the ideas and values of others due to our own ignorance.” This quote is one that can be considered
