Spending Variance. Garrison et al. (2015) define a spending variance as “the difference between the actual amount of the cost and how much the cost should have been, given the actual level of activity” (p. 401). A spending variance would be favorable if the cost is less than expected and unfavorable if a cost is more than expected for a period. Variances in spending can occur from a changing level in activity as well as changes in amounts purchased or changes in the prices of items that were purchased. Within the category of spending variance also fall price and quantity variances. Price variance occurs because of differences between actual amounts paid and what was expected to be paid, while quantity variances occur due to the difference…

The traditional variance analysis method actually is used in everywhere. There is one interesting discussion from Chenhall and Langfield-Smith in 1998 which examines the Australian accounting application. In Australia, the traditional and current development management accounting practices was widely accepted and applied. The authors believe that those traditional accounting methods such as variance analysis is much better than some new techniques (Chenhall & Langfield-Smith, 1998). The previous…

Variance Decomposition Analysis The variance decomposition analysis has applied to quantify the extent up to which the selected indices one influenced by each other. We can also examine the short run dynamic relationship by variance decomposition. While impulse response functions trace the effects of a shock to one endogenous variable in the VAR, variance decomposition separates the variation in an endogenous variable in to the component shocks to the VAR. Thus, the variance decomposition…

Data Analysis Biaxial Tensile Tests Different stress and strain definitions have been used to study the biomechanics of soft tissue [24]. The 2nd Piola-Kirchhoff stress and Green strain definitions have been employed in this study, which are described briefly in the following. The Green strain tensor is defined as E=1/2(F^T F-1), where F is the gradient deformation tensor. For the case of in-plane biaxial stretching in directions 1 and 2, the Green strain in these directions can be written…

attention—when people are focused on the same object or subject in their surroundings—is a critical component of language and communication learning for infants and children. Museums, specifically, offer visitors opportunities for free choice learning, but can also be very stimulating, with multiple options competing for visitors’ attention. However, there is no research addressing the role that joint attention can play in family learning talk in museums. In this study, the authors examined…
