Naval Combat System Product Line Architecture Economics
Acquisition Research Program Sponsored Report SeriesSponsored Acquisition Research & Technical ReportsA Model-Based Systems Engineering (MBSE) approach has been developed at the Naval Postgraduate School that integrates parametric cost and product modeling methods for economic trade-off analysis of system product lines. The research assesses the economic consequences of DoD product line options and has been refining a framework for others to use and adapt. This report provides details of the methodology and its application to several empirical case studies. The modeling framework includes a reference architecture and cost model for a general combat system product line that is extensible to other DoD and government domains. It has been applied to assess the economics of Navy combat system product line architecture approaches in coordinated case studies. The case studies were performed for a three-tier cruise missile system, the Aegis ship software product line, and an Anti-Submarine Warfare (ASW) cross-domain product line architecture for air, surface, and sub-surface applications. An overall business case analysis for DoD product line practices was performed synthesizing the case studies with recommendations generated.Approved for public release; distribution is unlimited.Approved for public release; distribution is unlimited
Site Selection for Joint Logistics over the Shore (JLOTS) Operations Using Multi- Objective Decision Analysis
As the U.S. military faces an increasing need to deploy across a range of military operations and environments, the ability to establish and sustain logistics support remains a major challenge. The Engineer Research and Development Center is currently developing the Planning Logistics Analysis Network System (PLANS), a decision support tool, to facilitate strategic and operational logistics planning. This paper describes a site selection protocol for logistics operations occurring without a suitable port, commonly referred to as Logistics over-the Shore (LOTS) operations. The model uses multi- objective decision analysis techniques to weight different operational criteria to determine the best overall site for logistics over the shore operations. This tool will enhance the time and accuracy in determining an optimal site that meets the decision maker’s specific operational needs
Canadian Children’s Literature: An Alberta Survey
This article presents the findings of an online survey administered to Alberta elementary school teachers in 2000-2001. The survey explored the teachers’ knowledge and use of Canadian children’s literature and their thoughts about the role of Canadian literature in elementary school classrooms. Canadian children’s trade books espouse particular images and values that assist young Canadians in developing a sense of their national and personal identities. Respondents expressed their thoughts about the advantages and disadvantages of using Canadian literature. Overall, most teachers appeared to be unfamiliar with contemporary Canadian books and included Canadian materials in their classroom instruction only for specific Canadian content.Cet article présente les résultats d’une enquête en ligne effectuée auprès d’enseignants à l’élémentaire en Alberta, en 2000-2001. L’enquête portait sur les connaissances des enseignants au sujet de la littérature canadienne pour jeunes, l’usage qu’ils en faisaient et leurs avis sur le rôle de la littérature canadienne à l’élémentaire. Les ouvrages canadiens d’intérêt général publiés pour les jeunes transmettent des images et des valeurs qui aident les jeunes Canadiens à se développer une identité nationale et personnelle. Les répondants se sont exprimés sur les bienfaits et les désavantages d’employer la littérature canadienne. De façon générale, la majorité des enseignants semblent ne pas bien connaître les livres canadiens contemporains et n’avaient recours à la littérature canadienne que pour son contenu spécifiquement canadien
A novel computerized test for detecting and monitoring visual attentional deficits and delirium in the ICU
Objectives: Delirium in the ICU is associated with poor outcomes
but is under-detected. Here we evaluated performance of a novel,
graded test for objectively detecting inattention in delirium, implemented
on a custom-built computerized device (Edinburgh Delirium
Test Box–ICU).
Design: A pilot study was conducted, followed by a prospective
case-control study.
Setting: Royal Infirmary of Edinburgh General ICU.
Patients: A pilot study was conducted in an opportunistic sample
of 20 patients. This was followed by a validation study in
30 selected patients with and without delirium (median age,
63 yr; range, 23–84) who were assessed with the Edinburgh
Delirium Test Box–ICU on up to 5 separate days. Presence
of delirium was assessed using the Confusion Assessment
Method for the ICU.
Measurements and Main Results: The Edinburgh Delirium Test
Box–ICU involves a behavioral assessment and a computerized
test of attention, requiring patients to count slowly presented
lights. Thirty patients were assessed a total of 79 times (n = 31, 23,
15, 8, and 2 for subsequent assessments; 38% delirious). Edinburgh
Delirium Test Box–ICU scores (range, 0–11) were lower
for patients with delirium than those without at the first (median, 0
vs 9.5), second (median, 3.5 vs 9), and third (median, 0 vs 10.5)
assessments (all p < 0.001). An Edinburgh Delirium Test Box–ICU
score less than or equal to 5 was 100% sensitive and 92% specific
to delirium across assessments. Longitudinally, participants’
Edinburgh Delirium Test Box–ICU performance was associated
with delirium status.
Conclusions: These findings suggest that the Edinburgh Delirium
Test Box–ICU has diagnostic utility in detecting ICU delirium
in patients with Richmond Agitation and Sedation Scale Score
greater than –3. The Edinburgh Delirium Test Box–ICU has potential
additional value in longitudinally tracking attentional deficits
because it provides a range of scores and is sensitive to change
Predicting breastfeeding in women living in areas of economic hardship : explanatory role of the theory of planned behaviour
This study employed the theory of planned behaviour (TPB) and additional variables (descriptive norm, moral norm, self-identity) to investigate the factors underlying breastfeeding intention and subsequent breastfeeding at four time points (during hospital stay, at hospital discharge, 10 days postpartum and 6 weeks postpartum) in a sample of women selected from defined areas of economic hardship (N = 248). A model containing the TPB, additional variables and demographic factors provided a good prediction of both intention (R-2 = 0.72; attitude, perceived behavioural control, moral norm and self-identity significant predictors) and behaviour - breastfeeding at birth (88.6% correctly classified; household deprivation, intention, attitude significant), at discharge from hospital (87.3% correctly classified; intention, attitude significant), 10 days after discharge (83.1% correctly classified; education, intention, attitude, descriptive norm significant) and 6 weeks after discharge (78.0% correctly classified; age, household deprivation, ethnicity, moral norm significant). Implications for interventions are discussed, such as the potential usefulness of targeting descriptive norms, moral norms and perceived behavioural control (PBC) when attempting to increase breastfeeding uptake
Triazine Resistant Pigweeds in Kentucky Corn Fields
Smooth pigweed (Amaranthus hybridus) control from atrazine and/or simazine (Princep) has been unsatisfactory in some Kentucky corn fields. Many of these fields have grown corn where one or both of these herbicides have been used continuously for several years. These two triazine herbicides, particularly atrazine, are used annually on over 90% of the corn grown in Kentucky. Other areas in the U.S. and around the world have reported. unsatisfactory control from atrazine where triazine resistant pigweed has developed
Faces on Mars Lesson: Incorporating Art, Thinking Skills, and Disability Differentiation Strategies for Twice-Exceptional Gifted Students
This practical article provides an example art-integrated lesson designed to serve gifted students with the exceptionalities of deficits in executive functioning and in impulse control. The lesson used the mysterious science problem of possible life on Mars as evidenced by anomalous faces in NASA photographs as a stimulus for practice in processing information through three Edward de Bono CoRT Thinking Skills. This lesson demonstrated differentiating instruction for gifted students with disabilities that included hands-on and peer-involved exercises. Examples of student work showing comic book-like stories about the famous Face on Mars are included, along with student responses to the thinking skill activities
