Health Promotion Practice and the Road Ahead: Addressing Enduring Gaps and Encouraging Greater Practice-to-Research Translation
A decade ago, Lancaster and Roe described four critical gaps (i.e., communications, accessibility, credibility, and expectations) between research and practice in health education and health promotion that formed the framework for this department. Despite considerable attention and some progress, these gaps persist and are barriers to interaction and translation between health promotion and health education research and practice. Looking to the next several years as the new Associate Editors for this department, we renew the department’s commitment toward addressing these enduring gaps around which we frame new questions and invite continued dialogue
Ozone Reduction Survey Results: The Fall 97 Ozone Report
The Annual Ozone Reduction telephone survey measures ground level ozone knowledge, attitudes, intentions, and behaviors and is given to Atlanta residents living and working in the 13 county ozone non-attainment area. The survey was conducted by the Applied Research Center at Georgia State University. Residents were randomly selected and interviewed from October 1st -- November 7th, 1997. Interviewing was conducted on weekdays from 10:00 a.m. to 9:15 p.m. Monday through Thursday, and 10:00 a.m. to 5:00 p.m. on Friday. Weekend interviewing was conducted Saturday 11:00 a.m. to 7:00 p.m. and Sunday 10:00 a.m. 6:00 p.m. Each number was contacted a minimum of 7 times, or until a final disposition was reached. The actual results collected were weighted using the most recent U.S. Census data on the state of Georgia.The results of the Survey are likely to contain some error. Ninety-five percent of the time, error due to the random selection process will be no more than 3.5 percentage points plus or minus the reported percentage for all Georgians. Error for subgroups is likely to be slightly larger. Other sources of error are caused by individuals refusing to participate in the interview and inability to connect with the selected telephone number. For the Fall 1997 survey, 1275 surveys were completed, a response rate of 66%. Every feasible effort is made to obtain a response and reduce the error, but the reader should be aware that some error is inherent in all research.Approximately 74% of respondents were white and 23% African American, 55% were female and 45% male. The mean age was 41 and, on average, respondents had completed some college course work. The median family income was 75,000 and 66% of those surveyed owned their residence

A novel physiological role for ARF1 in the formation of bidirectional tubules from the Golgi.
Capitalizing on CRISPR/Cas9 gene-editing techniques and super-resolution nanoscopy, we explore the role of the small GTPase ARF1 in mediating transport steps at the Golgi. Besides its well-established role in generating COPI vesicles, we find that ARF1 is also involved in the formation of long (∼3 µm), thin (∼110 nm diameter) tubular carriers. The anterograde and retrograde tubular carriers are both largely free of the classical Golgi coat proteins coatomer (COPI) and clathrin. Instead, they contain ARF1 along their entire length at a density estimated to be in the range of close packing. Experiments using a mutant form of ARF1 affecting GTP hydrolysis suggest that ARF1[GTP] is functionally required for the tubules to form. Dynamic confocal and stimulated emission depletion imaging shows that ARF1-rich tubular compartments fall into two distinct classes containing 1) anterograde cargoes and clathrin clusters or 2) retrograde cargoes and coatomer clusters
Prototyping the Semantics of a DSL using ASF+SDF: Link to Formal Verification of DSL Models
A formal definition of the semantics of a domain-specific language (DSL) is a
key prerequisite for the verification of the correctness of models specified
using such a DSL and of transformations applied to these models. For this
reason, we implemented a prototype of the semantics of a DSL for the
specification of systems consisting of concurrent, communicating objects. Using
this prototype, models specified in the DSL can be transformed to labeled
transition systems (LTS). This approach of transforming models to LTSs allows
us to apply existing tools for visualization and verification to models with
little or no further effort. The prototype is implemented using the ASF+SDF
Meta-Environment, an IDE for the algebraic specification language ASF+SDF,
which offers efficient execution of the transformation as well as the ability
to read models and produce LTSs without any additional pre or post processing.Comment: In Proceedings AMMSE 2011, arXiv:1106.596
Deconvolution of Images from BLAST 2005: Insight into the K3-50 and IC 5146 Star-Forming Regions
We present an implementation of the iterative flux-conserving Lucy-Richardson
(L-R) deconvolution method of image restoration for maps produced by the
Balloon-borne Large Aperture Submillimeter Telescope (BLAST). We have analyzed
its performance and convergence extensively through simulations and
cross-correlations of the deconvolved images with available highresolution
maps. We present new science results from two BLAST surveys, in the Galactic
regions K3-50 and IC 5146, further demonstrating the benefits of performing
this deconvolution.
We have resolved three clumps within a radius of 4.'5 inside the star-forming
molecular cloud containing K3-50. Combining the well-resolved dust emission map
with available multi-wavelength data, we have constrained the Spectral Energy
Distributions (SEDs) of five clumps to obtain masses (M), bolometric
luminosities (L), and dust temperatures (T). The L-M diagram has been used as a
diagnostic tool to estimate the evolutionary stages of the clumps. There are
close relationships between dust continuum emission and both 21-cm radio
continuum and 12CO molecular line emission.
The restored extended large scale structures in the Northern Streamer of IC
5146 have a strong spatial correlation with both SCUBA and high resolution
extinction images. A dust temperature of 12 K has been obtained for the central
filament. We report physical properties of ten compact sources, including six
associated protostars, by fitting SEDs to multi-wavelength data. All of these
compact sources are still quite cold (typical temperature below ~ 16 K) and are
above the critical Bonner-Ebert mass. They have associated low-power Young
Stellar Objects (YSOs). Further evidence for starless clumps has also been
found in the IC 5146 region.Comment: 13 pages, 12 Figures, 3 Table
