Measuring Community Programs and Policies in the Healthy Communities Study

Childhood obesity is a challenging public health issue facing communities throughout the U.S. Local efforts are believed to be essential to assuring environments that support physical activity and healthy food/beverage consumption among children and their families. However, little is known about how broadly and intensively communities are implementing combinations of programs and policies that address childhood nutrition, physical activity, and weight control. The Healthy Communities Study is a nationwide scientific study in diverse communities to identify characteristics of communities and programs that may be associated with childhood obesity. Data collection occurred in 2013–2015; data analysis will be completed in 2016. As part of the Healthy Communities Study, researchers designed a measurement system to assess the number and scope of community programs and policies and to examine possible associations between calculated “intensity” scores for these programs and policies and behavioral and outcome measures related to healthy weight among children. This report describes the protocol used to capture and code instances of community programs and policies, to characterize attributes of community programs and policies related to study hypotheses, and to calculate the intensity of combinations of community programs and policies (i.e., using the attributes of change strategy, duration, and reach)

Building Community Practice Competencies Globally through the Community Tool Box

People throughout the world are working together to improve conditions in which they live. Although the issues and resources vary by context, what people actually do to effect change—core competencies of assessment, planning, action, evaluation, and sustainability—may be quite similar. To examine what competencies may be most valued in community practice, this report uses data analytics for what users are accessing in the Community Tool Box http://ctb.ku.edu/. This free resource for community health and development, with over 1.7 million unique visitors annually from over 200 countries, showed a six-fold increase in users during the past year (from November 2011 to November 2012). When we examined what users were accessing, the results showed greater interest in some particular competencies such as assessing community needs and resources, developing strategic and action plans, and enhancing cultural competence. Patterns of use suggest that there may be core competencies valued by community members seeking to change conditions and outcomes that matter, which may help inform training and professional development for the millions of people worldwide working to promote health, human development, and social justice.&nbsp

A SIMULATION ENVIRONMENT FOR EVOLVING MULTIAGENT COMMUNICATION

A simulation environment has been created to support study of emergent communication. Multiple agents exist in a two-dimensional world where they must find food and avoid predators. While non-communicating agents may survive, the world is configured so that survival and fitness can be enhanced through the use of inter-agent communication. The goal with this version of the simulator is to determine conditions under which simple communication (signaling) emerges and persists during an evolutionary process.

Angular-Differential Cross Sections for H(2p) Formation in Intermediate-Energy Proton-Helium Collisions

Angular-differential cross sections for charge transfer with simultaneous emission of a photon in collisions of protons with helium atoms have been measured. The incident proton energies were 25, 50, and 100 keV and the center-of-mass scattering angles were between 0 and 2.0 mrad. In the experiment, hydrogen atoms that scattered through an angle θ were detected in coincidence with photons emitted perpendicular to the scattering plane with a wavelength between 1140 and 1400 Å. Differential cross sections for capture into the 2p state of the hydrogen atom were determined from the variation in the coincidence signal with θ. The experimental results are compared with the results of a classical trajectory Monte Carlo (CTMC) simulation and with the results of a calculation for H(2p) capture using the Coulomb-Brinkman-Kramers (CBK) approximation. The agreement between the experimental results and the CTMC calculation is good at all three energies while the agreement between the shape of the data and the CBK calculation is good at 50 and 100 keV

Challenge problem and milestones for : Nuclear Energy Advanced Modeling and Simulation (NEAMS) waste Integrated Performance and Safety Codes (IPSC).

This report describes the specification of a challenge problem and associated challenge milestones for the Waste Integrated Performance and Safety Codes (IPSC) supporting the U.S. Department of Energy (DOE) Office of Nuclear Energy Advanced Modeling and Simulation (NEAMS) Campaign. The NEAMS challenge problems are designed to demonstrate proof of concept and progress towards IPSC goals. The goal of the Waste IPSC is to develop an integrated suite of modeling and simulation capabilities to quantitatively assess the long-term performance of waste forms in the engineered and geologic environments of a radioactive waste storage or disposal system. The Waste IPSC will provide this simulation capability (1) for a range of disposal concepts, waste form types, engineered repository designs, and geologic settings, (2) for a range of time scales and distances, (3) with appropriate consideration of the inherent uncertainties, and (4) in accordance with robust verification, validation, and software quality requirements. To demonstrate proof of concept and progress towards these goals and requirements, a Waste IPSC challenge problem is specified that includes coupled thermal-hydrologic-chemical-mechanical (THCM) processes that describe (1) the degradation of a borosilicate glass waste form and the corresponding mobilization of radionuclides (i.e., the processes that produce the radionuclide source term), (2) the associated near-field physical and chemical environment for waste emplacement within a salt formation, and (3) radionuclide transport in the near field (i.e., through the engineered components - waste form, waste package, and backfill - and the immediately adjacent salt). The initial details of a set of challenge milestones that collectively comprise the full challenge problem are also specified

The mysteries of mammatus clouds: Observations and formation mechanisms

Mammatus clouds are an intriguing enigma of atmospheric fluid dynamics and cloud physics. Most commonly observed on the underside of cumulonimbus anvils, mammatus also occur on the underside of cirrus, cirrocumulus, altocumulus, altostratus, and stratocumulus, as well as in contrails from jet aircraft and pyrocumulus ash clouds from volcanic eruptions. Despite their aesthetic appearance, mammatus have been the subject of few quantitative research studies. Observations of mammatus have been obtained largely through serendipitous opportunities with a single observing system (e.g., aircraft penetrations, visual observations, lidar, radar) or tangential observations from field programs with other objectives. Theories describing mammatus remain untested, as adequate measurements for validation do not exist because of the small distance scales and short time scales of mammatus. Modeling studies of mammatus are virtually nonexistent. As a result, relatively little is known about the environment, formation mechanisms, properties, microphysics, and dynamics of mammatus. This paper presents a review of mammatus clouds that addresses these mysteries. Previous observations of mammatus and proposed formation mechanisms are discussed. These hypothesized mechanisms are anvil subsidence, subcloud evaporation/sublimation, melting, hydrometeor fallout, cloud-base detrainment instability, radiative effects, gravity waves, Kelvin-Helmholtz instability, Rayleigh-Taylor instability, and Rayleigh-Bénard-like convection. Other issues addressed in this paper include whether mammatus are composed of ice or liquid water hydrometeors, why mammatus are smooth, what controls the temporal and spatial scales and organization of individual mammatus lobes, and what are the properties of volcanic ash clouds that produce mammatus? The similarities and differences between mammatus, virga, stalactites, and reticular clouds are also discussed. Finally, because much still remains to be learned, research opportunities are described for using mammatus as a window into the microphysical, turbulent, and dynamical processes occurring on the underside of clouds. © 2006 American Meteorological Society

Discovery of Genes Essential for Heme Biosynthesis through Large-Scale Gene Expression Analysis

SummaryHeme biosynthesis consists of a series of eight enzymatic reactions that originate in mitochondria and continue in the cytosol before returning to mitochondria. Although these core enzymes are well studied, additional mitochondrial transporters and regulatory factors are predicted to be required. To discover such unknown components, we utilized a large-scale computational screen to identify mitochondrial proteins whose transcripts consistently coexpress with the core machinery of heme biosynthesis. We identified SLC25A39, SLC22A4, and TMEM14C, which are putative mitochondrial transporters, as well as C1orf69 and ISCA1, which are iron-sulfur cluster proteins. Targeted knockdowns of all five genes in zebrafish resulted in profound anemia without impacting erythroid lineage specification. Moreover, silencing of Slc25a39 in murine erythroleukemia cells impaired iron incorporation into protoporphyrin IX, and vertebrate Slc25a39 complemented an iron homeostasis defect in the orthologous yeast mtm1Δ deletion mutant. Our results advance the molecular understanding of heme biosynthesis and offer promising candidate genes for inherited anemias
