Applied process knowledge and market performance: the moderating effect of environmental uncertainty

Abstract: Challenges the idea of an unconditional and positive influence of knowledge on performance without regard to environmental uncertainty. Focuses on applied process knowledge spanning the supply chain (i.e. considers supplier, internal, and customer sources). A survey of 208 manufacturing firms found the association between applied process knowledge and firm market performance is positive and statistically significant when demand unpredictability is high (but not when low); statistically significant when product churning (uncertainty) is high (but not when low); and not moderated by core production or logistics process change. Firm size and production technology were also controlled. Firms that can determine the moderating effect of the different types of environmental uncertainty they face upon their knowledge‐performance relationship will perform better in terms of market performance indicators.

Stature estimation in prehistoric Native Americans of Ohio

Abstract: In the present report we investigate stature estimation techniques in a sample of 64 (35 male, 29 female) prehistoric Native Americans from Ohio. Because living stature is unknown for these 64 individuals, we use Fully's (1956) anatomical method to provide the best estimates of living stature. In this method all osseous components of skeletal height are measured and soft tissue correction is added. Comparisons of regression equations commonly used for stature estimation in prehistoric Eastern Woodland Native American populations, but developed for East Asian and East Asian—derived populations (using lower extremity components), show that these commonly used equations consistently yield stature estimates 2 to 8 cm in excess of the best estimates from Fully's method. Based on the skeletal height measures of the 64 individuals in the present sample, we develop regression equations for the estimation of stature. These equations yield stature estimates virtually identical to estimates from Fully's method and may prove useful for stature reconstruction in other prehistoric Eastern Woodland Native American populations.

Photometric properties of stellar populations in Galactic globular clusters: the role of the Mg-Al anticorrelation

Abstract: We have computed low-mass stellar models and synthetic spectra for an initial chemical composition that includes the full C-N, O-Na, and Mg-Al abundance anticorrelations observed in second-generation stars belonging to a number of massive Galactic globular clusters. This investigation extends a previous study that addressed the effect of only the C-N and O-Na anticorrelations seen in all globulars observed to date. We find that the impact of Mg-Al abundance variations at fixed [Fe/H] and helium abundance is negligible on stellar models and isochrones (from the main sequence to the tip of the red giant branch) and bolometric corrections, when compared to the effect of C-N and O-Na variations. We identify a spectral feature at 490–520 nm, for low-mass main sequence stars, caused by MgH molecular bands. This feature has a vanishingly small effect on bolometric corrections for Johnson and Stromgren filters that cover that spectral range. However, specific narrow-band filters able to target this wavelength region can be powerful tools for investigating the Mg-poor unevolved stars and highlight possible splittings of the main sequence due to variations of Mg abundances.
