TYPES OF GROUPS Categories‚ Aggregates‚ and Groups Social Category - people who share a social characteristic‚ such as a taxpayer‚ a woman‚ or a college student. Social Aggregate - people who happen to be at the same place at the same time‚ such as students waiting in line for concert tickets. ● A group is sometimes confused with a social category and a social aggregate. Although neither categories nor aggregates are groups‚ some of their members may form groups by interacting regularly

Introduction Aggregate demand is normally understood in the context of the total value of goods and services demanded by a given group of consumers at a given time period and at a given price (Brux 2007‚ p. 375). In other words‚ aggregate demand essentially refers to the value of goods and services consumers are willing to purchase at various price levels. In certain economic literature‚ the aggregate demand is often referred to as the ‘effective demand’ but it bears close similarity to the gross

Capital and Revenue Expenditures Edwin Bivens XACC- 291 06/08/2014 Capital and Revenue Expenditures: The Differences and Similarities. In order to be able to explain the differences between Capital Expenditure and Revenue Expenditure; I believe it is important to understand what each are: A capital expenditure is an amount spent to acquire or improve a long-term asset such as equipment or buildings. Usually the cost is recorded in an account classified as Property‚ Plant and

Aggregates for Concrete Aggregates are inert granular materials such as sand‚ gravel‚ or crushed stone that‚ along with water and cement‚ are an essential ingredient in concrete. Aggregates are the most mined materials in the world. For a good concrete mix‚ aggregates need to be clean‚ hard‚ strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. Aggregates‚ which account for 60 to 75 percent of the total volume

absorption capacity‚ and fineness modulus of a f ine aggregate sample and to plot a gradation curve for the sample. The scope of the experiment was limited to one aggregate sample only. In determining the SSD and oven-dry weights needed for calculation of specific gravities‚ a conical mold was used to reach an SSD condition and the sample was later dried in an oven. Sieve analysis determined the particle size distribution by sifting the aggregate through a series of eight sieves of different sixes

Aggregates is a major part of concrete‚ it is of urgent need that we look into the influence of aggregate on the fresh as well as hardened properties of concrete. Better grading of aggregate not only will show better results in the properties of the concrete but will also help in saving expensive materials such as cement‚ fly ash and admixture. In the comparative study of influence of the aggregate on high strength concrete‚ here is an attempt to study strength characteristics of cubes and cylinders

Why the aggregate demand curve slopes downward: To answer this question‚ we recall that the components of economy’s GDP: Y = C + I + G + NX We assume that government spending is fixed. The other three components: consumption‚ investment‚ and net exports depend on economic conditions and on the price level. 1. The price level and consumption: The wealth effect: Ex: The nominal value of a dollar is fixed‚ yet‚ the real value of a dollar is not fixed. Coca Pizza 1 $ 1 0.5$ 2 → A decrease
