Land Development under the Threat of Taking

This paper presents a model of the land developer's response to the threat of regulatory taking. It shows that the threat of regulation affects development timing and density differently than the regulation imposed with certainty. Planned development proceeds at a more rapid pace under the taking threat, whereas the development density varies systematically by location in a spatial land market. Further, property on which regulations are actually imposed will be developed later than planned when the demanded density is falling over time. Regulated property, however, may be developed even more quickly than planned when the demanded density is rising over time.     

Financial comparability and environmental diversity: an international context

Accounting and environmental management both hold improved resource‐use efficiency as an ultimate goal, but intermediate processes and objectives vary and consequently it is separately assessed within each discipline. This paper intends to make visible the globalizing trends in accounting practice, which aim to standardize financial reporting to produce comparable information so that shareholders can maximize their economic wealth. This paper seeks to contrast this comparability strategy with the apparent need for diversity in accounting information exhibited by actual accounting practices, the information needs of environmental management and, ultimately, the cultural needs of sustainable development. We argue that a more pluralistic model, that enables a holistic assessment of corporate performance and balances diverse stakeholder objectives, is better suited to an uncertain future. Implementation requires accountants and environmental managers jointly to create and test a new order of reporting. There are many practical challenges but most significantly accountants and environmental managers must combine to enhance the visibility and credibility of these diverse performance measures.

Plant-wide (BSM2) evaluation of reject water treatment with a SHARON-Anammox process.

In wastewater treatment plants (WWTPs) equipped with sludge digestion and dewatering systems, the reject water originating from these facilities contributes significantly to the nitrogen load of the activated sludge tanks, to which it is typically recycled. In this paper, the impact of reject water streams on the performance of a WWTP is assessed in a simulation study, using the Benchmark Simulation Model no. 2 (BSM2), that includes the processes describing sludge treatment and in this way allows for plant-wide evaluation. Comparison of performance of a WWTP without reject water with a WWTP where reject water is recycled to the primary clarifier, i.e. the BSM2 plant, shows that the ammonium load of the influent to the primary clarifier is 28% higher in the case of reject water recycling. This results in violation of the effluent total nitrogen limit. In order to relieve the main wastewater treatment plant, reject water treatment with a combined SHARON-Anammox process seems a promising option. The simulation results indicate that significant improvements of the effluent quality of the main wastewater treatment plant can be realized. An economic evaluation of the different scenarios is performed using an Operating Cost Index (OCI).     

Dissolving the research mystique

This paper reports on a research oriented accounting course designed for senior undergraduate and graduate students. Topic selection, hypothesis construction and a research proposal are developed within the course through four building block assignments and a scavenger hunt. As an awareness enhancer a journal search identifies specific accounting issues researched and/or discussed in the literature. An ideas matrix collects the essence of potential topics, and three topics are developed into hypotheses based on problem statements. The design of a project culminates in a research blueprint.
