Creating an Effective Regional Alignment Strategy for the U.S. Army

View the Executive SummaryAs the war in Afghanistan draws to a close, the Army increasingly is focused upon “regionally aligning” its forces. To do so effectively, however, it must undertake several initiatives. First, the Army must acknowledge and liberate the unique productive capabilities (talents) of each individual. Second, it must shift from process-oriented, industrial age personnel management to productivity-focused, information age talent management. Third, the Army must foster enduring human relationships between its organizations and the governments, militaries, and populations to which they are regionally aligned. Hand in hand with this, it must redesign its Force Generation Model to create regional expertise at both individual and organizational levels. Finally, the Army must ensure that regional alignment does not degrade the worldwide “flex” capabilities of its forces.https://press.armywarcollege.edu/monographs/1474/thumbnail.jp

Clinical features that identify children with primary immunodeficiency diseases

BACKGROUND: The 10 warning signs of primary immunodeficiency diseases (PID) have been promoted by various organizations in Europe and the United States to predict PID. However, the ability of these warning signs to identify children with PID has not been rigorously tested. OBJECTIVE: The main goal of this study was to determine the effectiveness of these 10 warning signs in predicting defined PID among children who presented to 2 tertiary pediatric immunodeficiency centers in the north of England. METHODS: A retrospective survey of 563 children who presented to 2 pediatric immunodeficiency centers was undertaken. The clinical records of 430 patients with a defined PID and 133 patients for whom detailed investigations failed to establish a specific PID were reviewed. RESULTS: Overall, 96% of the children with PID were referred by hospital clinicians. The strongest identifiers of PID were a family history of immunodeficiency disease in addition to use of intravenous antibiotics for sepsis in children with neutrophil PID and failure to thrive in children with T-lymphocyte PID. With these 3 signs, 96% of patients with neutrophil and complement deficiencies and 89% of children with T-lymphocyte immunodeficiencies could be identified correctly. Family history was the only warning sign that identified children with B-lymphocyte PID. CONCLUSIONS: PID awareness initiatives should be targeted at hospital pediatricians and families with a history of PID rather than the general public. Our results provide the general pediatrician with a simple refinement of 10 warning signs for identifying children with underlying immunodeficiency diseases. </jats:sec

Factors influencing carbon stocks and accumulation rates in eelgrass meadows across New England, USA

Increasing the protection of coastal vegetated ecosystems has been suggested as one strategy to compensate for increasing carbon dioxide (CO2) in the atmosphere as the capacity of these habitats to sequester and store carbon exceeds that of terrestrial habitats. Seagrasses are a group of foundation species that grow in shallow coastal and estuarine systems and have an exceptional ability to sequester and store large quantities of carbon in biomass and, particularly, in sediments. However, carbon stocks (Corg stocks) and carbon accumulation rates (Corg accumulation) in seagrass meadows are highly variable both spatially and temporally, making it difficult to extrapolate this strategy to areas where information is lacking. In this study, Corg stocks and Corg accumulation were determined at 11 eelgrass meadows across New England, representing a range of eutrophication and exposure conditions. In addition, the environmental factors and structural characteristics of meadows related to variation in Corg stocks were identified. The objectives were accomplished by assessing stable isotopes of δ13C and δ15N as well as %C and %N in plant tissues and sediments, measuring grain size and 210Pb of sediment cores, and through assessing site exposure. Variability in Corg stocks in seagrass meadows is well predicted using commonly measured environmental variables such as grain size distribution. This study allows incorporation of data and insights for the northwest Atlantic, where few studies on carbon sequestration by seagrasses have been conducted

Stabilities of nanohydrated thymine radical cations: insights from multiphoton ionization experiments and ab initio calculations

Multi-photon ionization experiments have been carried out on thymine-water clusters in the gas phase. Metastable H2O loss from T+(H2O)n was observed at n ≥ 3 only. Ab initio quantum-chemical calculations of a large range of optimized T+(H2O)n conformers have been performed up to n = 4, enabling binding energies of water to be derived. These decrease smoothly with n, consistent with the general trend of increasing metastable H2O loss in the experimental data. The lowest-energy conformers of T+(H2O)3 and T+(H2O)4 feature intermolecular bonding via charge-dipole interactions, in contrast with the purely hydrogen-bonded neutrals. We found no evidence for a closed hydration shell at n = 4, also contrasting with studies of neutral clusters

Species traits and geomorphic setting as drivers of global soil carbon stocks in seagrass meadows

Our knowledge of the factors that can influence the stock of organic carbon (OC) that is stored in the soil of seagrass meadows is evolving, and several causal effects have been used to explain the variation of stocks observed at local to national scales. To gain a global-scale appreciation of the drivers that cause variation in soil OC stocks, we compiled data on published species-specific traits and OC stocks from monospecific and mixed meadows at multiple geomorphological settings. Species identity was recognized as an influential driver of soil OC stocks, despite their large intraspecific variation. The most important seagrass species traits associated with OC stocks were the number of leaves per seagrass shoot, belowground biomass, leaf lifespan, aboveground biomass, leaf lignin, leaf breaking force and leaf OC plus the coastal geomorphology of the area, particularly for lagoon environments. A revised estimate of the global average soil OC stock to 20 cm depth of 15.4 Mg C ha−1 is lower than previously reported. The largest stocks were still recorded in Mediterranean seagrass meadows. Our results specifically identify Posidonia oceanica from the Mediterranean and, more generally, large and persistent species as key in providing climate regulation services, and as priority species for conservation for this specific ecosystem service

The invisible plan: how English teachers develop their expertise and the special place of adapting the skills of lesson planning

This paper analyses how English teachers learn to become expert designers of learning and why sharing that expertise is increasingly vital. Its conceptual framework is the widely recognised, empirically tested, five-stage developmental Dreyfus model of skill acquisition, exemplifying the development of teacher expertise, constituted by the “milestone” [m] and “transitory” [t] phases connecting with the five stages of: Novice [m], Advanced Beginner [t], Competent [m], Proficient [t] and Expert [m]. Teacher planning is analysed as one key tacit or non-tangible component of developing expertise. Focusing specifically on English teachers as key participants in this pioneer teacher cognition study, the defining characteristics of milestone stages of expertise development are explored with specific attention to the remarkably under-researched area of planning. We introduce three new categories, defining modes of planning: (i) visible practical planning, (ii) external reflective planning and (iii) internal reflective planning, demonstrating their role in teacher development through the Dreyfus five stages. English is a subject which suffers from frequent disruptive changes to curriculum and assessment: new learning designs are constantly demanded, making planning an ongoing challenge. The implications for practice include the importance of an explicit understanding of how teachers’ planning moves through the three phases from the very “visible” novice phase to the internal relatively “automatic” competent teacher and finally the seemingly “invisible” expert phase. Further research is needed to explore how English teachers can share planning expertise between the three phases to improve teachers’ skills and student learning
