Why do customers switch? The dynamics of satisfaction versus loyalty

Abstract: One of the most unexamined assumptions marketing firms have made in recent years is that satisfaction alone will guarantee customer loyalty. Our research questions this assumption. We explored the correspondence between customer satisfaction and loyalty, and found as many as half of the “satisfied” customers to be predisposed to switching service suppliers. This satisfaction‐loyalty gap reflects the fact that different components of service quality drive satisfaction versus loyalty. Satisfaction is driven more by “technical quality” (the quality of the work performed) than by “functional quality” (how the service work was delivered); however, once satisfaction is achieved, loyalty is driven more by functional than by technical quality. This is the pattern of influence for a “low contact” (where customers’ direct contact with service providers is absent or marginal) service. For a “high contact” service, the pattern of influence is exactly the reverse. Of significant importance to service managers, the paper explains the dynamics of loyalty versus satisfaction and derives their managerial implications.

Red edge spectral measurements from sugar maple leaves

Abstract: Many sugar maple stands in the northeastern United States experienced extensive insect damage during the 1988 growing season. Chlorophyll data and high spectral resolution spectrometer laboratory reflectance data were acquired for multiple collections of single detached sugar maple leaves variously affected by the insect over the 1988 growing season. Reflectance data indicated consistent and diagnostic differences in the red edge portion (680-750 nm) of the spectrum among the various samples and populations of leaves. These included differences in the red edge inflection point (REIP), a ratio of reflectance at 740-720 nm (RE3/RE2), and a ratio of first derivative values at 715-705 nm (D715/D705). All three red edge parameters were highly correlated with variation in total chlorophyll content. Other spectral measures, including the Normalized Difference Vegetation Index (NDVI) and the Simple Vegetation Index Ratio (VI), also varied among populations and over the growing season, but did not correlate well with total chlorophyll content. Leaf stacking studies on light and dark backgrounds indicated REIP, RE3/RE2 and D715/D705 to be much less influenced by differences in green leaf biomass and background condition than either NDVI or VI.

A genome-wide view of the spectrum of spontaneous mutations in yeast

Abstract: The mutation process ultimately defines the genetic features of all populations and, hence, has a bearing on a wide range of issues involving evolutionary genetics, inheritance, and genetic disorders, including the predisposition to cancer. Nevertheless, formidable technical barriers have constrained our understanding of the rate at which mutations arise and the molecular spectrum of their effects. Here, we report on the use of complete-genome sequencing in the characterization of spontaneously arising mutations in the yeast Saccharomyces cerevisiae. Our results confirm some findings previously obtained by indirect methods but also yield numerous unexpected findings, in particular a very high rate of point mutation and skewed distribution of base-substitution types in the mitochondrion, a very high rate of segmental duplication and deletion in the nuclear genome, and substantial deviations in the mutational profile among various model organisms.
