NEW DEVELOPMENTS IN GROCERY MANUFACTURER AND DISTRIBUTOR MARKETING PROGRAMS: A SURVEY OF U.S. WHOLESALERS AND RETAILERS
The retail food industry has taken initiatives to improve cost and to return the focus of management to the consumer. Among these initiatives are Efficient Consumer Response (ECR) and category management. A mail questionnaire elicited perceptions on these issues from 95 executives among U.S. food wholesalers and retailers. This study found that ECR category management are being used to streamline costs and to remove logistical inefficiencies. Although it is widely recognized that category management provides a consumer focus, distributors seemingly brush aside tactics that target individual customers in favor of efforts that target logistical efficiency.Agribusiness, Marketing,
Virtual Investment Concepts and the Ethanol Industry
The fast-growing US ethanol industry has historically been characterized by large downstream investments made by farmers. The authors assess the value which the stock market may hold for downstream investment by farmers as well as by ethanol manufacturers themselves. The model framework used herein expands on the original VEST framework developed by Siebert, Jones and Sporleder. A word of caution, the model herein is not intended to provide an on-going, risk-reducing business strategy. However, it can and does provide a quick method to calculate the reasonableness of a downstream investment request that a farmer (or any business person) might be challenged to consider. Although virtual stock market investments may certainly assist in value added performance, they (just like brick and mortar processing plants) can provide no guarantee of performance.cooperatives, corn, equities, ethanol, value added, Resource /Energy Economics and Policy, Q10, Q32,
Magnetic states and optical properties of single-layer carbon-doped hexagonal boron nitride
We show that carbon-doped hexagonal boron nitride (h-BN) has extraordinary
properties with many possible applications. We demonstrate that the
substitution-induced impurity states, associated with carbon atoms, and their
interactions dictate the electronic structure and properties of C-doped h-BN.
Furthermore, we show that stacking of localized impurity states in small C
clusters embedded in h-BN forms a set of discrete energy levels in the wide gap
of h-BN. The electronic structures of these C clusters have a plethora of
applications in optics, magneto-optics, and opto-electronics
Relative stability of extended interstitial defects in silicon: First-principles calculations
Interstitials stored in {311} or {111} habit planes form rows of interstitial chains elongated in ⟨011⟩ direction. Exploiting the large aspect ratio to treat chains as infinite, first-principles calculations of large computation supercells reveal a unique formation energy trend for each defect, which is closely correlated with its distinct shape. The most energetically favorable structure changes from {311} rodlike defects to Frank loops as the number of interstitials in the defect increases. These results are consistent with transmission electron microscopy studies
Glacial cycles drive variations in the production of oceanic crust
Glacial cycles redistribute water between oceans and continents causing
pressure changes in the upper mantle, with consequences for melting of Earth's
interior. Using Plio-Pleistocene sea-level variations as a forcing function,
theoretical models of mid-ocean ridge dynamics that include melt transport
predict temporal variations in crustal thickness of hundreds of meters. New
bathymetry from the Australian-Antarctic ridge shows significant spectral
energy near the Milankovitch periods of 23, 41, and 100 ky, consistent with
model predictions. These results suggest that abyssal hills, one of the most
common bathymetric features on Earth, record the magmatic response to changes
in sea level. The models and data support a link between glacial cycles at the
surface and mantle melting at depth, recorded in the bathymetric fabric of the
sea floor.Comment: 30 pages, 6 figures (including supplementary information).

How does leadership affect information systems success? The role of transformational leadership
We examined the positive impact of transformational leadership on IS success in organizations via two psychological mechanisms of system users’—perceived organizational support and systems self-efficacy. Our conceptual model was assessed using a sample of 251 employees from a multi-national bank in Korea. Overall, our results supported the hypothesized relationships: transformational leadership was positively related to system users’ IS success, and both perceived organizational support and systems self-efficacy of the system users mediated the relationship between transformational leadership and IS success. The results call for manager’s attention to the importance of transformational leadership development in organizations
Evidence for the Galactic X-ray Bulge II
A mosaic of 5 \ros~PSPC pointed observations in the Galactic plane
() reveals X-ray shadows in the keV band cast by
distant molecular clouds. The observed on-cloud and off-cloud X-ray fluxes
indicate that % and % of the diffuse X-ray background in this
direction in the \tq~keV and 1.5 keV bands, respectively, originates behind the
molecular gas which is located at 3 kpc from the Sun. The implication of
the derived background X-ray flux beyond the absorbing molecular cloud is
consistent with, and lends further support to recent observations of a Galactic
X-ray bulge.Comment: 19 pages, 5 figures, 2 table
Predictability of helminth parasite host range using information on geography, host traits and parasite community structure
© Cambridge University Press 2016. Host-parasite associations are complex interactions dependent on aspects of hosts (e.g. traits, phylogeny or coevolutionary history), parasites (e.g. traits and parasite interactions) and geography (e.g. latitude). Predicting the permissive host set or the subset of the host community that a parasite can infect is a central goal of parasite ecology. Here we develop models that accurately predict the permissive host set of 562 helminth parasites in five different parasite taxonomic groups. We developed predictive models using host traits, host taxonomy, geographic covariates, and parasite community composition, finding that models trained on parasite community variables were more accurate than any other covariate group, even though parasite community covariates only captured a quarter of the variance in parasite community composition. This suggests that it is possible to predict the permissive host set for a given parasite, and that parasite community structure is an important predictor, potentially because parasite communities are interacting non-random assemblages
