Developing a Serious Game to Explore Joint All Domain Command and Control
Changes in the geopolitical landscape and increasing technological complexity have prompted the U.S. Military to coin Multi-Domain Operations (MDO) and Joint All-Domain Command and Control as terms to describe an over-arching strategy that frames the complexity of warfare across both traditional and emerging warfighting domains. Teaching new and advanced concepts associated with these terms requires both innovation as well as distinct education and training tools in order to realize the cultural change advocated by senior military leaders. BSN, a Collectible Card Game, was developed to teach concepts integral to MDO and initiate discussion on military strategy
Addressing the mental health needs of the rural underserved: Findings from a multiple case study of a behavioral telehealth project
Behavioral telehealth is a reasonable solution to the accessibility to mental health care problem that exists in many rural communities. This paper reports the results of a multiple case study of a behavioral telehealth program administered through a marriage and family therapy training program. The results suggest that mental health services can be effectively delivered using existing distance education technology to underserved rural populations. Rural communities have unique barriers to accessing mental health care, some of which can be overcome through the distance delivery of services and some of which cannot. In order to effectively deliver treatment, accommodations to the technology must be made by both therapist and client
Evolution of architectural floor plans
Layout planning is a process of sizing and placing rooms (e.g. in a house)
while a t t empt ing to optimize various criteria. Often the r e are conflicting
c r i t e r i a such as construction cost, minimizing the distance between r e l a t ed
activities, and meeting the area requirements for these activities. The process of layout planning ha s mostly been done by hand, wi th a handful of
a t t empt s to automa t e the process. Thi s thesis explores some of these pa s t
a t t empt s and describes several new techniques for automa t ing the layout
planning process using evolutionary computation. These techniques a r e inspired by the existing methods, while adding some of the i r own innovations.
Additional experimenLs are done to t e s t the possibility of allowing polygonal
exteriors wi th rectilinear interior walls. Several multi-objective approaches
are used to evaluate and compare fitness. The evolutionary r epr e s ent a t ion
and requirements specification used provide great flexibility in problem scope
and depth and is worthy of considering in future layout and design a t t empt s .
The system outlined in thi s thesis is capable of evolving a variety of floor
plans conforming to functional and geometric specifications. Many of the
resulting plans look reasonable even when compared to a professional floor
plan. Additionally polygonal and multi-floor buildings were also generated
Evidence of strategic periodicities in collective conflict dynamics
We analyze the timescales of conflict decision-making in a primate society.
We present evidence for multiple, periodic timescales associated with social
decision-making and behavioral patterns. We demonstrate the existence of
periodicities that are not directly coupled to environmental cycles or known
ultraridian mechanisms. Among specific biological and socially-defined
demographic classes, periodicities span timescales between hours and days, and
many are not driven by exogenous or internal regularities. Our results indicate
that they are instead driven by strategic responses to social interaction
patterns. Analyses also reveal that a class of individuals, playing a critical
functional role, policing, have a signature timescale on the order of one hour.
We propose a classification of behavioral timescales analogous to those of the
nervous system, with high-frequency, or -scale, behavior occurring on
hour-long scales, through to multi-hour, or -scale, behavior, and,
finally periodicities observed on a timescale of days.Comment: 22 pages, 7 figures, 1 table. Accepted for publication in Journal of

(S)-(+)-1-(2-Bromophenyl)ethanol
The title compound, C8H9BrO, crystallizes with two molecules in the asymmetric unit. The structure displays O—H⋯O hydrogen bonding, generating zigzag chains evolving around a screw axis along [100]
1,3,5,7-Tetrakis(4-iodophenyl)adamantane benzene tetrasolvate
The title molecule, C34H28I4·4C6H6, has crystallographic symmetry and crystallizes with four symmetry-related benzene solvent molecules. The phenyl group is eclipsed with one of the adamantane C—C bonds. The tetraphenyladamantane units and the benzene solvent molecules are connected by weak intermolecular phenyl–benzene C—H⋯π and benzene–benzene C—H⋯π interactions. In the crystal, molecules are linked along the c-axis direction via the iodophenyl groups by a combination of weak intermolecular I⋯I [3.944 (1) Å] and I⋯π(phenyl) [3.608 (6) and 3.692 (5) Å] interactions
Tris(ethane-1,2-diamine-κ2 N,N′)cobalt(II) cis-aqua-2κO-μ-cyanido-1:2κ2 C:N-heptacyanido-1κ7 C-bis(ethane-1,2-diamine-2κ2 N,N′)cobalt(II)molybdenum(IV) dihydrate
The title compound, [Co(C2H8N2)3][CoMo(CN)8(C2H8N2)2(H2O)]·2H2O, is isostructural with the NiII analogue. The MoIV atom is coordinated by eight cyanide ligands, one of which forms a bridge to a CoII atom that is itself coordinated by two bidentate ethane-1,2-diamine (en) ligands and one water molecule. Another CoII complex, coordinated to three bidentate en ligands, acts as the counter-ion. The crystal structure contains O—H⋯N/O, N—H⋯N/O and C—H⋯N/O hydrogen bonds, which form a three-dimensional network
Achieving urban water conservation: a handbook

Diethyl 2,5-bis[(1E)-(1H-pyrrol-2-ylmethylidene)amino]thiophene-3,4-dicarboxylate
In the crystal structure of the title compound, C20H20N4O4S, the azomethine group adopt E conformations. The pyrrole units are twisted by 10.31 (4) and 18.90 (5)° with respect to the central thiophene ring. The three-dimensional network is close packed and involves N—H⋯O, N—H⋯N, C—H⋯N and C—H⋯O hydrogen bonding
Aging, Resistance Training, and Diabetes Prevention
With the aging of the baby-boom generation and increases in life expectancy, the American population is growing older. Aging is associated with adverse changes in glucose tolerance and increased risk of diabetes; the increasing prevalence of diabetes among older adults suggests a clear need for effective diabetes prevention approaches for this population. The purpose of paper is to review what is known about changes in glucose tolerance with advancing age and the potential utility of resistance training (RT) as an intervention to prevent diabetes among middle-aged and older adults. Age-related factors contributing to glucose intolerance, which may be improved with RT, include improvements in insulin signaling defects, reductions in tumor necrosis factor-α, increases in adiponectin and insulin-like growth factor-1 concentrations, and reductions in total and abdominal visceral fat. Current RT recommendations and future areas for investigation are presented
