Sea Control in the Arctic: A Soviet Perspective

In the Punic Wars, Hannibal surprised and strategically dislocated the Roman legions by attacking them with his war elephants as he made his way across what had been considered to be an insurmountable geographical barrier, the Alps. In a similar fashion, recent developments in Soviet Arctic mobility and logistics give the Soviets the capability to inflict strategic surprise on the West. Although there is no evidence that the Soviets intend to implement the strategic plans or concepts of operations discussed here, they do possess substantial capabilities in the Arctic which could threaten the United States and Canada. U.S. and Canadian strategists must consider these capabilities in determining our territorial defense plans and our Arctic defense forces

The Journey of American Capitalism: From Stockholders to Stakeholders

The American practice of capitalism has been nothing short of dynamic. The struggle to find an acceptable method of ‘the proper administration of wealth’ has been a key issue since at least the days of Andrew Carnegie. In the early years of American industrialization, the focus was largely and legally on stockholder rights. This focus shifted somewhat towards the benefit of labor as unions gained power in the early 20th century. Then, the stakeholder view began to take root and grow in the last half of the 20th century. This view expanded the conversation of capitalists vs. labor to include other stakeholders. This research reviews history and literature on the journey of American capitalism and takes the additional step of addressing expectations of corporate governance changes in the near future and the impact millennials are likely to have on the journey

Life in the Trenches: The Archeological Investigation of the Federal Picket Line near the Crater, Petersburg National Battlefield

Archeologists from the University of Maryland conducted an excavation of the Federal picket line within Petersburg National Battlefield as part of the Overview and Assessment of archeological resources within the battlefield's Main Unit. The goal of the Overview and Assessment is to provide basic background information on the archeological resources within the battlefield park. This includes, describing the area's environmental and culture history; list, describe, and evaluate known archeological resources; describe the potential for as-yet- unidentified archeological resources; outline relevant research topics; and provide recommendations for future research. As part of the Overview and Assessment project, National Park Service staff and University of Maryland archeologists agreed that part of the project should provide a public component. To help further both goals of evaluating archeological resources and public visibility, project directors decided to explore the archeological potential of the Federal picket line near the Crater. The Federal picket line, in this area of the battlefield, played a vital role in the Battle of the Crater on July 30, 1864. The picket line also served as a key area because of its proximity, 100 yards, from the Confederate defenses. This was one of the closest points between the two armies. This report contains details from the excavation and public interpretation portions of the project. Excavation details focus on the data recovered from the four excavation units used to bisect the picket trench. Archeologists were able to excavate and record a seven foot section of the Federal picket trench, and features associated with the Battle of the Crater. Archeological features and data also provide details on the post-war filling and history of the picket trench area. Artifacts recovered from the trench, including pieces of preserved canvas, leather, tin cups, ink well fragments, food tins, and other militaria, provide clues to the daily lives of soldiers posted in the trench. Details on the public interpretation portion include information on the development, methodology, and success of the major components of the public program. These details, including descriptions of the project website, tour brochures, exhibits, and site tours, provide a template for future archeology interpretative programs

African Americans and Appomattox Manor Within the Structured Landscape of the Eppes Plantation

The Civil War brought about many changes in Virginian society, including the area around City Point, Virginia. These changes greatly effected the manner in which plantation owners managed their farms. Plantation owners had to find new ways of obtaining and exploiting their labor, and protecting their resources. The goal of this report is to explore those changes between the years 1851 and 1872 on the Eppes' plantations. I examine how Dr. Eppes structured his landscape to aid in controlling his productive resources, and the relationship he held with African-Americans. Part of exploring that relationship will be examining the living conditions of African-Americans on the Eppes' plantations as slaves and freedmen laborers. Dr. Eppes' home, Appomattox Manor, and its grounds now make up the City Point Unit of the Petersburg National Battlefield. This report will place the City Point Unit into its larger historic context. Though the unit is best known as the location of General Grant's headquarters during the Siege of Petersburg, its history is far more extensive. In this report, I place City Point and Appomattox Manor in the plantation context which surrounded them before and after the war. It will show how the Civil War was not an isolated event, but was effected by and affected the social world around it

Making space for embedded knowledge in global mental health: a role for social work

The ‘Global Mental Health’ (GMH) movement, an influential driver of transnational knowledge transfer in the field of mental health, advocates evidence-based strategies to ‘scale up’ services in low- and middle-income countries. As with debates on global and local frameworks for social work, there are concerns about marginalisation of knowledge that does not neatly fit the GMH discourse. This article analyses the professional and disciplinary structures that shape knowledge transfer in GMH and the implications for social work's engagement with the movement. Analysis of key documents and secondary literature identifies three key issues for GMH: its potentially negative impact on ‘local’ knowledge production; the challenges of accounting for culture and context; and the selective forms of evidence that are ‘allowed’ to contribute to GMH. Finding ways to encompass more ‘situated’ perspectives could reshape GMH in accord with its aspirations for participation by a wider range of stakeholders. Social work's values-based commitment to rights and empowerment, emphasis on embedded knowledge emerging from close links with practice, and theoretical engagement with social, cultural and political context, enable the profession to contribute significantly to this task. Such engagement would bring improvements in care for those suffering from mental health disorders, their families and communities

Fossilized skin reveals coevolution with feathers and metabolism in feathered dinosaurs and early birds

Feathers are remarkable evolutionary innovations that are associated with complex adaptations of the skin in modern birds. Fossilised feathers in non-avian dinosaurs and basal birds provide insights into feather evolution, but how associated integumentary adaptations evolved is unclear. Here we report the discovery of fossil skin, preserved with remarkable nanoscale fidelity, in three non-avian maniraptoran dinosaurs and a basal bird from the Cretaceous Jehol biota (China). The skin comprises patches of desquamating epidermal corneocytes that preserve a cytoskeletal array of helically coiled α-keratin tonofibrils. This structure confirms that basal birds and non-avian dinosaurs shed small epidermal flakes as in modern mammals and birds, but structural differences imply that these Cretaceous taxa had lower body heat production than modern birds. Feathered epidermis acquired many, but not all, anatomically modern attributes close to the base of the Maniraptora by the Middle Jurassic

Health systems changes after decentralisation: Progress, challenges and dynamics in Pakistan

Decentralisation is widely practised but its scrutiny tends to focus on structural and authority changes or outcomes. Politics and process of devolution implementation needs to be better understood to evaluate how national governments use the enhanced decision space for bringing improvements in the health system and the underlying challenges faced. We use the example of Pakistan\u27s radical, politically driven provincial devolution to analyse how national structures use decentralisation opportunities for improved health planning, spending and carrying out transformations to the health system. Our narrative draws on secondary data sources from the PRIMASYS study, supplemented with policy roundtable notes from Pakistan. Our analysis shows that in decentralised Pakistan, health became prioritised for increased government resources and achieved good budgetary use, major strides were made contextualised sector-wide health planning and legislations, and a proliferation seen in governance measures to improve and regulate healthcare delivery. Despite a disadvantaged and abrupt start to devolution, high ownership by politicians and bureaucracy in provincial governments led to resourcing, planning and innovations. However, effective translation remained impeded by weak institutional capacity, feeble federal-provincial coordination and vulnerability to interference by local elites. Building on this illustrative example, we propose (1) political management of decentralisation for effective national coordination, sustaining stable leadership and protecting from political interfere by local elites; (2) investment in stewardship capacity in the devolved structures as well as the central ministry to deliver on new roles

Identifying dynamical modules from genetic regulatory systems: applications to the segment polarity network

BACKGROUND It is widely accepted that genetic regulatory systems are 'modular', in that the whole system is made up of smaller 'subsystems' corresponding to specific biological functions. Most attempts to identify modules in genetic regulatory systems have relied on the topology of the underlying network. However, it is the temporal activity (dynamics) of genes and proteins that corresponds to biological functions, and hence it is dynamics that we focus on here for identifying subsystems. RESULTS Using Boolean network models as an exemplar, we present a new technique to identify subsystems, based on their dynamical properties. The main part of the method depends only on the stable dynamics (attractors) of the system, thus requiring no prior knowledge of the underlying network. However, knowledge of the logical relationships between the network components can be used to describe how each subsystem is regulated. To demonstrate its applicability to genetic regulatory systems, we apply the method to a model of the Drosophila segment polarity network, providing a detailed breakdown of the system. CONCLUSION We have designed a technique for decomposing any set of discrete-state, discrete-time attractors into subsystems. Having a suitable mathematical model also allows us to describe how each subsystem is regulated and how robust each subsystem is against perturbations. However, since the subsystems are found directly from the attractors, a mathematical model or underlying network topology is not necessarily required to identify them, potentially allowing the method to be applied directly to experimental expression data

Range corrections for two-neutron halo nuclei in effective theory

The range corrections to the universal properties and structure of two-neutron halo nuclei are investigated within an effective quantum mechanics framework. Treating the nucleus as an effective three-body system, we make a systematic improvement upon previous calculations by calculating the linear range corrections at next-to-leading order. Since the effective ranges for the neutron-core interactions are not known, we estimate the effective range to be set by the inverse of the pion mass. We investigate the possibility of excited Efimov states in two-neutron halo nuclei and calculate their mean square radii to next-to-leading order. We find that the effective range corrections are generally small and the leading order predictions are very robust.Comment: 19 pages, 4 eps figures, revtex4, final version to appear in Nucl. Phys.
