Monte Carlo experimentation is a well-known approach used to test the performance of alternative methodologies under different hypotheses. In the frontier analysis framework, whatever the parametric or non-parametric methods tested, experiments to date have been developed assuming single output multi-input production functions. The data generated have mostly assumed a Cobb–Douglas technology. Among other drawbacks, this simple framework does not allow the evaluation of DEA performance on scale efficiency measurement. The aim of this paper is twofold. On the one hand, we show how reliable two-output two-input production data can be generated using a parametric output distance function approach. A variable returns to scale translog technology satisfying regularity conditions is used for this purpose. On the other hand, we evaluate the accuracy of DEA technical and scale efficiency measurement when sample size and output ratios vary. Our Monte Carlo experiment shows that the correlation between true and estimated scale efficiency is dramatically low when DEA analysis is performed with small samples and wide output ratio variations.

Now in its second edition, Exercises for Voice Therapy provides speech-language pathologists with step-by-step instruction for developing session materials for clients-both children and adults-with all types of voice disorders. The new edition includes 17 new expert contributors and 24 new exercises, provinding a greater assortment of exercises and targeting a larger variety of voice disorders. The exercises vary in difficulty and all follow the same format for easy integration into speech-language pathologists' therapy sessions.The accompanying CD contains recordings of many of the exercises to provide an aural model for those that may be difficult to interpret from the text alone.

Many geophysical inverse problems are ill-posed leading to non-uniqueness of the solution. It is thus important to reduce the amount of mathematical solutions to more geologically plausible models by regularizing the inverse problem and incorporating all available prior information in the inversion process. We compare three different ways to go beyond standard Occam’s inversion for electrical resistivity tomography (ERT) using electromagnetic logging data in the context of salt water infiltration: a simple reference model, a structural constraint and a geostatistical constraint based on a vertical correlation length. Results with the traditional smoothness constraint yield small contrasts of resistivity, far from the reality revealed by borehole measurements. Incorporating prior information from boreholes clearly improves the misfit with logging data. If a good reference model can always be used, it can lead to misinterpretation if its weight is too strong. When the computation of the correlation length is possible, the geostatistical inversion gives satisfactory results everywhere in the section. In this specific case, the geostatistical approach seems to be a more robust way to incorporate prior information. The structural constraint seems to be more indicated when integrating information from other geophysical methods such as GPR or seismic. [less ▲]

Copper contamination of soils represents a threat to natural areas and to human health. Phytostabilization, i.e using plants to immobilize contaminants, represents a well-known technology to hemper heavy metals spread across landscapes. In Katanga (Congo D.R.), Microchloa altera was recently identified as a candidate species to stabilize copper in soil. This grass naturally tolerates and accumulates high copper concentrations and belongs to the typical copper flora of Katanga. However more than 600 species compose this flora and other grasses may be used in phytostabilisation strategies. But little is known about the phenology reproductive strategy and demography of these species, which makes their use in current phytostabilization strategies difficult. The present study aims to characterize the reproduction capacity of seven other dominant grass species for future phytostabilisation tests. A total of 67 quadrats (1m²) were randomly placed across three sites. At two periods over the fruiting season, three inflorescences per species per quadrat were collected in order to estimate the number of spikes, spikelets and viable seeds. All species have sexual reproductive strategy and spikelets number presents little variation between populations. Three species are very common (Andropogon shirensis, Loudetia simplex and Eragrostis racemosa) and represent potential candidates to increase species diversity in phytostabilization strategies in Katanga. Further research, including germination tests and phytostabilization tests in situ, is planned in a near future. [less ▲]
