The present paper examines the effectiveness of financial overcompensation as a means to enhance customer loyalty after a product failure. Overcompensation implies that customers are entitled to a refund that is larger than the purchase price. It is, however, still unclear whether large overcompensations entail saturation effects, or alternatively, result in an actual drop in customer loyalty. ...

 The effectiveness of hydrocarbon bioremediation strategies approaches is depending on various issues such as type and volume of pollution, nutrient accessibility in the target ecosystem, time, biodiversity of microorganisms, pollutant bioavailability and many others. In the present research, laboratory studies were carried out on the bioremediation of coastal sediment samples ...

Several methods have been proposed for ranking the decision-making units (DMUs) in data envelopment analysis (DEA) with imprecise data. Some methods have only used the upper bound efficiencies to rank DMUs. However, some other methods have considered both of the lower and upper bound efficiencies to rank DMUs. The current paper shows that these methods did not consider the DEA axioms and may be...

It is well known that the efficiency of noiseless coding may be improved by coding extensions of the source; for large extensions the efficiency is arbitrarily close to unity. This paper shows that the efficiency is not always improved just by coding the next extension. In some cases the code of a larger extension is markedly less efficient than its predecessor, although always within the theor...

Catalytic efficiencies of proteinase K and mesentericopeptidase were determined using series of peptide-4-nitroanilide substrates and compared with those of subtilisin DY, savinase and esperase. For each enzyme the subsites S1-S4 were characterized. The data for the enzyme specificities were related to our high resolution X-ray models of the five enzymes and their complexes with peptides. The c...

Synopsis: Some trucking companies have begun to look outside their operations for additional efficiencies by “cooperating with competitors,” i .e. with other carriers. This has been referred to as Collaborative Transportation Management. We present simple examples where a firm (i .e. a trucking company or an organization that has its own private fleet ) can enhance its transportation efficienci...

The sizeof the compensating orifice in the slipper of hydrostatic units has an important influence on the volumetric, mechanical, and overall efficiencies. A simple model was derived to predict the changes in efficiencies caused byfirst reducing and then blanking the orifice. Testing in a hydrostatic unit was performed to measure the effects of the slipper orifice design on efficiency. Comparis...

John M. Marsh (406) 994-5621 [email protected] Cost efficiencies are an important factor in the red meat industry. These efficiencies refer to technological changes, resource configurations, and management strategies that result in firms reducing per unit costs of output (including risk). Cost efficiencies in livestock and meat marketing are critical for the economic survival of firms that com...

An innovative class of coupling gratings for efficiently redirecting light beams is described. They are based on symmetric binary gratings equipped with an asymmetric high refractive index coating. This kind of structure exhibits a grating blaze effect and produces high diffraction efficiencies. Coupling gratings based on the described principle have been fabricated by UV casting and subsequent...
