Review Essay—Adaptation and the School of War: Mars Adapting: Military Change during War

Retired Marine officer and National Defense University research fellow Frank Hoffman’s Mars Adapting is, first and foremost, a work of military theory. Hoffman initially achieved notoriety for his work and briefs about something he characterized as hybrid or compound warfare, since popularized alongside the rise in interest in gray-zone conflict. This book’s major contribution is similarly theoretical, but in the area of institutional learning, not modalities of war. Hoffman argues “for greater consideration of Organizational Learning Theory [OLT] to establish an analytical framework.

Determining the 7Li(n,gamma) cross section via Coulomb dissociation of 8Li

The applicability of Coulomb dissociation reactions to determine the cross section for the inverse neutron capture reaction was explored using the reaction 8Li(gamma,n)7Li. A 69.5 MeV/nucleon 8Li beam was incident on a Pb target, and the outgoing neutron and 7Li nucleus were measured in coincidence. The deduced (n,gamma) excitation function is consistent with data for the direct capture reaction 7Li(n,gamma)8Li and with low-energy effective field theory calculations.Comment: Accepted for publication in Phys.

Fiddling while the ice melts? How organizational scholars can take a more active role in the climate change debate

The debate over anthropogenic climate change or the idea that human activities are altering the physical climate of the planet continues to rage amid seemingly irreconcilable differences, both within the developed world and between developed and less developed countries. With high uncertainty, rival worldviews, and wide diversity of meaning attached to the expression, climate change has become a key narrative within which local and transnational issues – economic, social, and political – are framed and contested. The field is fraught with controversies regarding causes and consequences, as well as different attitudes toward risks, technologies, and economic and social well-being for different groups. Parties also dispute how to share responsibility for reducing emissions – whether the issue primarily needs market, regulatory, technological, or behavioral solutions. Climate change is many things to many people. Competing interests negotiate over its interpretation and utilize various strategies to promote practices that advance their own understandings regarding climate change and its governance

Petrologic and Geochemical Composition of the AND-2A Core, ANDRILL Southern McMurdo Sound Project, Antartica

The compositional record of the AND-2A drillcore is examined using petrological, sedimentological, volcanological and geochemical analysis of clasts, sediments and pore waters. Preliminary investigations of basement clasts (granitoids and metasediments) indicate both local and distal sources corresponding to variable ice-volume and ice-flow directions. Low abundance of sedimentary clasts (e.g., arkose, litharenite) suggests reduced contributions from sedimentary covers while intraclasts (e.g., diamictite, conglomerate) attest to intrabasinal reworking. Volcanic material includes pyroclasts (e.g., pumice, scoria), sediments and lava. Primary and reworked tephra layers occur within the Early Miocene interval (1093 to 640 metres below sea floor). The compositions of volcanic clasts reveal a diversity of alkaline types derived from the McMurdo Volcanic Group. Finer-grained sediments (e.g., sandstone, siltstone) show increases in biogenic silica and volcanic glass from 230 to 780 mbsf and higher proportions of terrigenous material ca. 350 to 750 mbsf and below 970 mbsf. Basement clast assemblages suggest a dominant provenance from the Skelton Glacier - Darwin Glacier area and from the Ferrar Glacier - Koettlitz Glacier area. Provenance of sand grains is consistent with clast sources. Thirteen Geochemical Units are established based on compositional trends derived from continuous XRF scanning. High values of Fe and Ti indicate terrigenous and volcanic sources, whereas high Ca values signify either biogenic or diagenic sources. Highly alkaline and saline pore waters were produced by chemical exchange with glass at moderately elevated temperatures

Pragmatism over principle: US intervention and burden shifting in Somalia, 1992–1993

The conventional wisdom about the 1992 US intervention in Somalia is that it was a quintessentially humanitarian mission pushed by President George H. W. Bush. This article challenges that interpretation, drawing on newly declassified documents. The Somalia intervention, I argue, was largely a pragmatic response to concerns held by the US military. In late 1992, as the small UN mission in Somalia was collapsing, senior American generals worried about being drawn into the resulting vacuum. Hence they reluctantly recommended a robust US intervention, in the expectation that this would allow the UN to assemble a larger peacekeeping force that would take over within months. The intervention ultimately failed, but the military learned useful lessons from this experience on how to achieve smoother UN handoffs in the future and thus effectively shift longer-term stabilisation burdens to the international community.Open access publication was made possible by an EC Career Integration Grant

What Makes People Anxious About Life after the Age of 65?- Evidence from International Survey Research in Japan, the United States, and China

In order to respond to the social security needs of an increasingly aged population, many governments with limited budgets are required to focus available resources on the direct causes of people's anxieties about aging. This study investigated the causes of people's anxieties about life after the age of 65 using household data from countries with different social contexts: Japan, the United States, and China. This research uncovered three major findings. First, the speed of population aging does not always make people anxious about life at an older age. Second, high financial status effectively lessens people's levels of anxiety about their older years in Japan and the United States. Third, living with a child does not necessarily lessen people's concern about life after 65

Linear Responses in Time-dependent Hartree-Fock-Bogoliubov Method with Gogny Interaction

A numerical method to integrate the time-dependent Hartree-Fock Bogoliubov (TDHFB) equations with Gogny interaction is proposed. The feasibility of the TDHFB code is illustrated by the conservation of the energy, particle numbers, and center-of-mass in the small amplitude vibrations of oxygen 20. The TDHFB code is applied to the isoscalar quadrupole and/or isovector dipole vibrations in the linear (small amplitude) region in oxygen isotopes (masses A = 18,20,22 and 24), titanium isotopes (A = 44,50,52 and 54), neon isotope (A = 26), and magnesium isotopes (A = 24 and 34). The isoscalar quadrupole and isovector dipole strength functions are calculated from the expectation values of the isoscalar quadrupole and isovector dipole moments.Comment: 10 pages, 13 figure
