Just -in -time selling: Relation to market orientation, organizational structure and organizational performance

The purpose of this dissertation is to answer the following research questions related to the efficacy of a Just-in-Time (JIT) selling strategy: (1) What is the nature of the relationships among market orientation, JIT selling, organizational structure, and organizational performance constructs? (2) Does JIT selling mediate and/or moderate the relationships among market orientation and organizational structure and organizational performance? The market orientation model theorized by Kohli and Jaworski (1990) and the JIT selling model theorized and tested by Germain, Dröge and Daugherty (1994) and Claycomb, Dröge and Germain (1999) are combined to facilitate investigation of the link between market orientation and JIT selling. Generally, the combined model incorporates market orientation as an antecedent to JIT selling and organizational structure and performance as consequences. Data relating to all constructs were collected from 177 marketing oriented representatives from manufacturing firms using a combined Internet survey and traditional mailing methodology. A multiple regression and structural equation modeling approach returned results indicating that market orientation and JIT selling are positively linked, that market orientation and JIT selling are positively associated with organizational performance and with the integration, formalization and specialization components of organizational structure but not with the decentralization component. JIT selling partially mediates the relationship between market orientation and organizational performance but neither mediates nor moderates the relations among market orientation and integration, formalization and specialization. Managers implementing a JIT selling strategy within the context of an organization exhibiting a high market orientation may expect improvements in organizational performance. A JIT selling strategy requires development of long-term, single-source relationships with buyers and efforts by the organization\u27s sales representatives to build value during the selling process based on established organizational abilities to deliver zero-defect products precisely on-time and in the precise quantities desired by customers while minimizing total waste and total cost throughout the supply chain

Supply Chain Finance: Impact on Supply Chain Competency and Organizational Performance

Supply chain finance (SCF) has begun to garner some attention in the supply chain management literature, yet we find no empirical works assessing the role that SCF plays within a supply chain context and the impact it has on supply chain competency (SCC) and organizational performance (OP). This paper is an attempt to fill this literature gap in supply chain management and provide empirical evidence on the role of SCF. This study employs a structural equations model to investigate the role of SCF in the context of supply chain management on U.S. manufacturing firms. The results map SCF in the center of the supply chain management spectrum with supply chain management strategy (SCMS) and information sharing (IS) as the antecedents to, and SCC and OP as the consequences of SCF. Supply chain finance, together with supply chain competency positively impacts 51% of the variations in organizational performance.  

Spacecraft Charging Test Considerations for Composite Materials

Composite materials present a growing challenge for spacecraft charging assessments. We review some recent lessons learned for charging tests of composite materials using both parallel-plate and electron beam test geometries. We also discuss examples of materials that exhibit significant variations between samples, despite them all having the same trade name

Age-based disparities in end-of-life decisions in Belgium: a population-based death certificate survey

<p>Abstract</p> <p>Background</p> <p>A growing body of scientific research is suggesting that end-of-life care and decision making may differ between age groups and that elderly patients may be the most vulnerable to exclusion of due care at the end of life. This study investigates age-related disparities in the rate of end-of-life decisions with a possible or certain life shortening effect (ELDs) and in the preceding decision making process in Flanders, Belgium in 2007, where euthanasia was legalised in 2002. Comparing with data from an identical survey in 1998 we also study the plausibility of the ‘slippery slope’ hypothesis which predicts a rise in the rate of administration of life ending drugs without patient request, especially among elderly patients, in countries where euthanasia is legal.</p> <p>Method</p> <p>We performed a post-mortem survey among physicians certifying a large representative sample (n = 6927) of death certificates in 2007, identical to a 1998 survey. Response rate was 58.4%.</p> <p>Results</p> <p>While the rates of non-treatment decisions (NTD) and administration of life ending drugs without explicit request (LAWER) did not differ between age groups, the use of intensified alleviation of pain and symptoms (APS) and euthanasia/assisted suicide (EAS), as well as the proportion of euthanasia requests granted, was bivariately and negatively associated with patient age. Multivariate analysis showed no significant effects of age on ELD rates. Older patients were less often included in decision making for APS and more often deemed lacking in capacity than were younger patients. Comparison with 1998 showed a decrease in the rate of LAWER in all age groups except in the 80+ age group where the rate was stagnant.</p> <p>Conclusion</p> <p>Age is not a determining factor in the rate of end-of-life decisions, but is in decision making as patient inclusion rates decrease with old age. Our results suggest there is a need to focus advance care planning initiatives on elderly patients. The slippery slope hypothesis cannot be confirmed either in general or among older people, as since the euthanasia law fewer LAWER cases were found.</p

Immune Predictors of Mortality After Ribonucleic Acid Virus Infection

Background Virus infections result in a range of clinical outcomes for the host, from asymptomatic to severe or even lethal disease. Despite global efforts to prevent and treat virus infections to limit morbidity and mortality, the continued emergence and re-emergence of new outbreaks as well as common infections such as influenza persist as a health threat. Challenges to the prevention of severe disease after virus infection include both a paucity of protective vaccines as well as the early identification of individuals with the highest risk that may require supportive treatment. Methods We completed a screen of mice from the Collaborative Cross (CC) that we infected with influenza, severe acute respiratory syndrome-coronavirus, and West Nile virus. Results The CC mice exhibited a range of disease manifestations upon infections, and we used this natural variation to identify strains with mortality after infection and strains exhibiting no mortality. We then used comprehensive preinfection immunophenotyping to identify global baseline immune correlates of protection from mortality to virus infection. Conclusions These data suggest that immune phenotypes might be leveraged to identify humans at highest risk of adverse clinical outcomes upon infection, who may most benefit from intensive clinical interventions, in addition to providing insight for rational vaccine design

The James Webb Space Telescope Mission

Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized space telescope with an aperture of at least $4m$. With the support of their governments in the US, Europe, and Canada, 20,000 people realized that vision as the $6.5m$ James Webb Space Telescope. A generation of astronomers will celebrate their accomplishments for the life of the mission, potentially as long as 20 years, and beyond. This report and the scientific discoveries that follow are extended thank-you notes to the 20,000 team members. The telescope is working perfectly, with much better image quality than expected. In this and accompanying papers, we give a brief history, describe the observatory, outline its objectives and current observing program, and discuss the inventions and people who made it possible. We cite detailed reports on the design and the measured performance on orbit.Comment: Accepted by PASP for the special issue on The James Webb Space Telescope Overview, 29 pages, 4 figure

Rare coding variants in PLCG2, ABI3, and TREM2 implicate microglial-mediated innate immunity in Alzheimer's disease

We identified rare coding variants associated with Alzheimer’s disease (AD) in a 3-stage case-control study of 85,133 subjects. In stage 1, 34,174 samples were genotyped using a whole-exome microarray. In stage 2, we tested associated variants (P<1×10-4) in 35,962 independent samples using de novo genotyping and imputed genotypes. In stage 3, an additional 14,997 samples were used to test the most significant stage 2 associations (P<5×10-8) using imputed genotypes. We observed 3 novel genome-wide significant (GWS) AD associated non-synonymous variants; a protective variant in PLCG2 (rs72824905/p.P522R, P=5.38×10-10, OR=0.68, MAFcases=0.0059, MAFcontrols=0.0093), a risk variant in ABI3 (rs616338/p.S209F, P=4.56×10-10, OR=1.43, MAFcases=0.011, MAFcontrols=0.008), and a novel GWS variant in TREM2 (rs143332484/p.R62H, P=1.55×10-14, OR=1.67, MAFcases=0.0143, MAFcontrols=0.0089), a known AD susceptibility gene. These protein-coding changes are in genes highly expressed in microglia and highlight an immune-related protein-protein interaction network enriched for previously identified AD risk genes. These genetic findings provide additional evidence that the microglia-mediated innate immune response contributes directly to AD development
