9 – Standard costing
Publisher Summary 
This chapter discusses standard costing. A standard cost is defined as a predetermined calculation of how much costs should be under specified working conditions. The Terminology goes on to explain that a standard cost is built up from an assessment of the value of cost elements and correlates technical specifications and the quantification of materials, labor and other costs to the prices and/or wage rates expected to apply during this period in which the standard cost is expected to be used. The Terminology envisages that such standards would be used as established control tools through variance analysis, inventory valuation and even for fixing prices. Standards can be set for direct materials, both price and usage, for direct labor, and for indirect fixed or variable conversion expenses. Within the context of the operating of standard costing, the difference between the goal set and the results achieved can be quantified, analyzed, and hopefully, unambiguously communicated. At the very outset, the emphasis on analysis is vital because whereas the variance itself directs attention to its existence, it is the skill in analysis that correctly draws attention to the reason.
Behavioral Properties of Variance Controls
The behavioral implications of variance controls have generally been ignored. This paper examines the characteristics of variance controls, traces their use in modern organizations, and suggests further areas for application and improvement.
Soil organic matter and microbiological development of technosols in the South Wales Coalfield
Abstract Degraded land (formerly ‘reclaimed’) after surface-coal-mining is a serious problem in South Wales. This project uses forestation to foster soil development on opencast coal-mine spoil technosols. It compares records of humification and the soil microbiological system (microcoenosis) using paired data from the same plantings in 1998 and 2018. Statistical analysis finds no significant difference between samples collected under trees planted by the pit-planting versus trench planting method or trees planted using organic or mineral fertilizer. However, there are strong significant differences in both soil organic matter and microflora components and significant correlations with time since tree planting. Most components of the soil organic carbon (TOC) and the microflora increase, often significantly. However, compared to 2018, 1998 samples contain significantly greater maximum levels of Insoluble Carbon while the microflora had significantly more Ammonifying bacteria. Decreases in Insoluble Carbon explain the relatively small increase in TOC between 1998 and 2018. The % extracted with 0.1 N H2SO4 is significantly larger in 2018, suggesting active weathering. Similarly, both the maxima and minima of total Humic and Fulvic acids content, extracted with 0.1 M Na4P2O7 + 0.1 M NaOH, are significantly greater in 2018. Total microflora shows significant positive correlations with time-since-tree-planting as do the proportions of bacilli and actinomycetes but the correlation with ammonifying bacteria is negative. In 1998, the microflora was dominated by non-spore-forming bacteria while, in 2018, bacilli and actinomycetes prevail; both are involved in the transformation of complex organic compounds and humification. This indicates active transformation of more complex organic compounds and advancing humification. In sum, forestation of these degraded, formerly reclaimed, opencast coal-mine spoils has resulted in a massive increase in both the size and functioning of the soil organic system.
