This study evaluates the effectiveness of an intervention package including a discrete trial program (Rapid Motor Imitation Antecedent Training (Tsiouri and Greer, J Behav Educat 12:185-206, 2003) combined with parent education for eliciting first words in children with ASD who had little or no spoken language. Evaluation of the approach includes specific intervention targets and functional spo...

An issue of considerable importance, both from a practical organizational standpoint and from a costs research perspectives, involves the allocation of /xed resources or costs across a set of competing entities in an equitable manner. Cook and Kress (Eur. J. Oper. Res. 119 (1999) 652) propose a data envelopment analysis (DEA) approach to obtain a theoretical framework for such cost allocation p...

Aquatic microbes produce diverse secondary metabolites with interesting biological activities. Cytotoxic metabolites have the potential to become lead compounds or drugs for cancer treatment. Many cytotoxic compounds, however, show undesirable toxicity at higher concentrations. Such undesirable activity may be reduced or eliminated by using lower doses of the cytotoxic compound in combination w...

The electronic absorption spectra of oxidized and reduced spinach ferredoxins have been measured between 1200 and 600 nm at low temperature in D(2)O/ethylene glycol glasses. Relatively weak absorption bands are observed at 720, 820, and 920 nm in oxidized ferredoxin, and at 652, 820, and 920 nm in reduced ferredoxin. The spectral results show that the two Fe(III) centers in oxidized ferredoxin ...
