What are the Jones and modified Jones model of aggregate accruals in earnings management?

The original Jones model of non-discretionary accruals was developed by J. Jones in a 1991 paper in which she asserted that firms under the scope for import relief would engage in income-reducing earnings management.
It is a cross-sectional regression model:
Non-discretionary accruals = OLScoeff(1)(1/Assets) + OLScoeff(2)(chg in Rev) + OLScoeff(3)(gross PPE) + error of estimates
This original model has been refined many times to include the modified-Jones model which tweaks the second factor changing it from OLScoeff(2)(chg in Rev - chg in Rcvbls)
Both are among the several regression tests for earnings management but the limitation of all regression tests of EM is that (1) the power of the tests are generally low (partially explain variation if and when detected), and (2) they are all ex post measures (lagging).
Additional models include the industry model and the Healy model.

What are the models for earning management?
The earnings depends on what buisness you are working for and what you are modeling. If by earnings management models you are referring to earnings management research that has evolved with positive accounting theory, then it is important to note many models exists. Positive accounting theory (PAT) centers on the economic consequences of accounting choices. The broad stroke of the theory states that managers may be influenced to manipulate earnings away from "true earnings". In the effort to further expand PAT, researchers have approached the detection of earnings management in 2 general ways. The first way is to examine the income values of filing firms to determine whether they are zero or slightly less than zero. Theoretically, the expectation is that income should have a smooth distribution, however, Burgstahler and Dichev noted an "earnings kink" around zero. Another way to examine earnings management is by examining the 'level' of abnormal accruals believed to present in the income values--an example of some of these models include the Jones and modified Jones model.
What is the modified Jones model?
Hi, Modified Jones Model which is recognized by name a type of old Jones Model that can very useful for measuring nondiscretionary accruals within a regression.
Why although concrete components are elastic concrete is inelastic?
Well this is not quite true. Aggregate is a key component of concrete and is inelastic. In addition concrete pillars and beams will bend slightly under load and is thus not 100% inelastic. Polymer modified concrete and rebar modified concrete is also slightly elastic.
What about dry and wet impact value in aggregate test?
OBJECTIVE For determination of the aggregate impact value of coarse aggregate, which passes 12.5 mm. IS sieve and retained on 10 mm. IS sieve. Aggregate impact value test gives an indication of aggregate’s toughness property (i.e. property of a material to resist impact) Aggregate impact values are used to classify the stone aggregates with respect to toughness property as given below. The test equipment and the test procedure are quite simple and it determines the resistance to impact of stone aggregates simulating field condition. This test can be performed even at construction site or at stone quary, as the apparatus is simple and portable. Aggregate impact value test also gives an indirect indication of the strength characteristics of aggregate. Aggregate impact value of a sample also depends on the shape factors such as flakiness index and elongation index of the aggregates. It has been found that for majority of aggregates, the aggregate crushing value and aggregate impact values are numerically similar within close limits. For deciding the suitability of soft aggregates in base course construction, aggregate impact test is commonly used. A modified impact test is also often carried out in the case of soft aggregates to find the wet impact value after soaking the test sample in water. Maximum allowable aggregate impact value of aggregate in different types of pavement material / layers.
