Why Range Forage Quality Changes

Range livestock and wildlife have access to a tremendous diversity of forage plants which vary in nutritional quality. Range animals get the nutrients (protein, energy, vitamins, and minerals) required for growth, reproduction, and milk production from these plants. Nutritional quality is affected by plant part, plant age, plant group, season of growth, weather, soils and range sites, stocking rates, and secondary compounds. Animal species (cattle, goats, deer, etc.) affects the plant group used and potential digestibility

New approach for sensor simulation for Hardware In the Loop test systems

International audienceAutomatic test systems can evaluate the functionality of measurement and/or control hardware by simulating real world signals and verifying the expected response. Simulation takes the dynamics of real-world environments and models them using software to test the performance of critical system hardware components. Sensor simulation is the process of providing realistic sensor signals to the inputs of a device under test and evaluating how a piece of equipment will respond across a broad range of operating conditions. This paper will discuss the benefits of sensor simulation, and specifically reference the additional advantages to using an FPGA-based implementation

Efficiency Analysis of Competing Tests for Finding Differentially Expressed Genes in Lung Adenocarcinoma

In this study, we introduce and use Efficiency Analysis to compare differences in the apparent internal and external consistency of competing normalization methods and tests for identifying differentially expressed genes. Using publicly available data, two lung adenocarcinoma datasets were analyzed using caGEDA (http://bioinformatics2.pitt.edu/GE2/GEDA.html) to measure the degree of differential expression of genes existing between two populations. The datasets were randomly split into at least two subsets, each analyzed for differentially expressed genes between the two sample groups, and the gene lists compared for overlapping genes. Efficiency Analysis is an intuitive method that compares the differences in the percentage of overlap of genes from two or more data subsets, found by the same test over a range of testing methods. Tests that yield consistent gene lists across independently analyzed splits are preferred to those that yield less consistent inferences. For example, a method that exhibits 50% overlap in the 100 top genes from two studies should be preferred to a method that exhibits 5% overlap in the top 100 genes. The same procedure was performed using all available normalization and transformation methods that are available through caGEDA. The ‘best’ test was then further evaluated using internal cross-validation to estimate generalizable sample classification errors using a Naïve Bayes classification algorithm. A novel test, termed D1 (a derivative of the J5 test) was found to be the most consistent, and to exhibit the lowest overall classification error, and highest sensitivity and specificity. The D1 test relaxes the assumption that few genes are differentially expressed. Efficiency Analysis can be misleading if the tests exhibit a bias in any particular dimension (e.g. expression intensity); we therefore explored intensity-scaled and segmented J5 tests using data in which all genes are scaled to share the same intensity distribution range. Efficiency Analysis correctly predicted the ‘best’ test and normalization method using the Beer dataset and also performed well with the Bhattacharjee dataset based on both efficiency and classification accuracy criteria

A lifecycle analysis of complex public procurement: an agency-institutional theory perspective

PurposeThe study sets out to demonstrate how a lifecycle perspective on complex, public-sector procurement projects can be used for making qualitative assessments of procurement policy and practice and reveal those procurement capabilities that are most impactful for operating effectively.Design/methodology/approachAgency theory, institutional theory and the lifecycle analysis technique are combined to abductively develop a framework to identify, analyse and compare complex procurement policies and practices in public sector organisations.

A lifecycle analysis of complex public procurement: an agency-institutional theory perspective

Purpose: The study sets out to demonstrate how a lifecycle perspective on complex, public-sector procurement projects can be used for making qualitative assessments of procurement policy and practice and reveal those procurement capabilities that are most impactful for operating effectively. Design/Methodology/Approach: An agency-institutional theoretic perspective and a lifecycle analysis technique are combined to abductively develop a framework to identify, analyse and compare complex procurement policies and practices in public sector organisations. Defence is the focal case and is compared with cases in the Nuclear, Local Government and Health sectors. Findings and practical implications: The study provides a framework for undertaking a lifecycle analysis to understand the challenges and capabilities of complex, public-sector buyers. Eighteen hierarchically-arranged themes are identified and used in conjunction with agency and institutional theories to explain complex procurement policy and practice variation in some of the UK’s highest-profile public buyers. Our findings provide a classification of complex buyers and offer valuable guidance for practitioners and researchers navigating complex procurement contexts. Originality/Value: The lifecycle approach proposed is a new research tool providing a bespoke application of theory by considering each lifecycle phase as an individual but related element that is governed by unique institutional pressures and agency-theoretic relationships.
