Homeless Aging Veterans in Transition: A Life-Span Perspective
Carla J. Thompson,Nancy L. Bridier
Journal of Aging Research , 2013, DOI: 10.1155/2013/570407
Abstract: The need for counseling and career/educational services for homeless veterans has captured political and economic venues for more than 25 years. Veterans are three times more likely to become homeless than the general population if veterans live in poverty or are minority veterans. This mixed methods study emphasized a life-span perspective approach for exploring factors influencing normative aging and life-quality of 39 homeless veterans in Alabama and Florida. Seven descriptive quantitative and qualitative research questions framed the investigation. Study participants completed a quantitative survey reflecting their preferences and needs with a subset of the sample ( ) also participating in individual qualitative interview sessions. Thirty-two service providers and stakeholders completed quantitative surveys. Empirical and qualitative data with appropriate triangulation procedures provided interpretive information relative to a life-span development perspective. Study findings provide evidence of the need for future research efforts to address strategies that focus on the health and economic challenges of veterans before they are threatened with the possibility of homelessness. Implications of the study findings provide important information associated with the premise that human development occurs throughout life with specific characteristics influencing the individual’s passage. Implications for aging/homelessness research are grounded in late-life transitioning and human development intervention considerations. 1. Introduction The special population of homeless veterans has become an alarming concern within America’s aging population challenges. According to the National Coalition for Homeless Veterans [1], while only 7% of the US population is comprised of veterans, approximately 13% of the adult homeless populations are veterans. Recent national survey efforts conducted by the Veterans’ Administration and related government agencies report that 8.6% of homeless veterans are over the age of 62 with aging female homeless veteran populations increasing each year [2]. Veterans are three times more likely to become homeless than the general population if they live in poverty or are minority veterans in poverty. “Low income veterans are twice as likely to become homeless than the general population of low-income adults” [1, paragraph 2]. Almost half of homeless veterans in the United States are over the age of 51 and are comprised primarily of veterans representing the Baby Boomers and are veterans of the Vietnam War years [3].

Preventing Chronic Disease , 2008,
Abstract: IntroductionImpaired fasting glucose (IFG) often progresses to type 2 diabetes. Given the severity and prevalence of this disease, primary prevention is important. Intensive lifestyle counseling interventions have delayed or prevented the onset of type 2 diabetes, but it is not known whether less intensive, more easily replicable efforts can also be effective.MethodsIn a lifestyle intervention study designed to reduce risks for type 2 diabetes, 200 American Indian women without diabetes, aged 18 to 40 years, were recruited from an urban community without regard to weight or IFG and block-randomized into intervention and control groups on the basis of fasting blood glucose (FBG). Dietary and physical activity behaviors were reported, and clinical metabolic, fitness, and body composition measures were taken at baseline and at periodic follow-up through 18 months. American Indian facilitators used a group-discussion format during the first 6 months to deliver a culturally influenced educational intervention on healthy eating, physical activity, social support, and goal setting. We analyzed a subset of young American Indian women with IFG at baseline (n = 42), selected from both the intervention and control groups.ResultsAmong the women with IFG, mean FBG significantly decreased from baseline to follow-up (P < .001) and converted to normal (<5.6 mmol/L or <100 mg/dL) in 62.0% of the 30 women who completed the 18-month follow-up, irrespective of participation in the group educational sessions. Other improved metabolic values included significant decreases in mean fasting blood total cholesterol and low-density lipoprotein cholesterol levels. The women reported significant overall mean decreases in intake of total energy, saturated fat, total fat, total sugar, sweetened beverages, proportion of sweet foods in the diet, and hours of TV watching.ConclusionVolunteers with IFG in this study benefited from learning their FBG values and reporting their dietary patterns; they made dietary changes and improved their FBG and lipid profiles. If confirmed in larger samples, these results support periodic dietary and body composition assessment, as well as glucose monitoring among women with IFG.
Mal/SRF Is Dispensable for Cell Proliferation in Drosophila
Barry J. Thompson
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0010077
Abstract: The Mal/SRF transcription factor is regulated by the level of G-actin in cells and has important roles in cell migration and other actin-dependent processes in Drosophila. A recent report suggests that Mal/SRF and an upstream regulator, Pico, are required for cell proliferation and tissue growth in Drosophila. I find otherwise. Mutation of Mal or SRF does not affect cell proliferation in the fly wing. Furthermore, I cannot reproduce the reported effects of Pico RNAi or Pico overexpression on body size. Nevertheless, I can confirm that overexpression of Pico or Mal causes tissue overgrowth specifically in the fly wing - where SRF is most highly expressed. My results indicate that Mal/SRF can promote tissue growth when abnormally active, but is not normally required for tissue growth during development.
Highlights of GeV gamma-ray astronomy
D. J. Thompson
Astrophysics and Space Sciences Transactions (ASTRA) , 2010, DOI: 10.5194/astra-6-59-2010
Abstract: Because high-energy gamma rays are primarily produced by high-energy particle interactions, the gamma-ray survey of the sky by the Fermi Gamma-ray Space Telescope offers a view of sites of cosmic ray production and interactions. Gamma-ray bursts, pulsars, pulsar wind nebulae, binary sources, and Active Galactic Nuclei are all phenomena that reveal particle acceleration through their gamma-ray emission. Diffuse Galactic gamma radiation, Solar System gamma-ray sources, and energetic radiation from supernova remnants are likely tracers of high-energy particle interactions with matter and photon fields. This paper will present a broad overview of the constantly changing sky seen with the Large Area Telescope (LAT) on the Fermi spacecraft.

Helioseismology over the solar cycle
M. J. Thompson
Physics , 2010,
Abstract: Helioseismology has produced unprecedented measurements of the Sun's internal structure and dynamics over the past 25 years. Much of this work has been based on global helioseismology. Now local helioseismology too is showing its great promise. This review summarizes very briefly the principal global results that may be relevant to an understanding of the origins of solar magnetism. Recent results regarding the variation of frequencies over the solar cycle and the temporal variations of subsurface flows are briefly summarized.
Reaction mechanisms of pair transfer
Ian J. Thompson
Physics , 2012,
Abstract: The mechanisms of nuclear transfer reactions are described for the transfer of two nucleons from one nucleus to another. Two-nucleon overlap functions are defined in various coordinate systems, and their transformation coefficients given between coordinate systems. Post and prior couplings are defined for sequential transfer mechanisms, and it is demonstrated that the combination of `prior-post' couplings avoids non-orthogonality terms, but does not avoid couplings that do not have good zero-range approximations. The simultaneous and sequential mechanisms are demonstrated for the $^{124}$Sn(p,t)$^{122}$Sn reaction at 25 MeV using shell-model overlap functions. The interference between the various simultaneous and sequential amplitudes is shown.
Measurements of alpha_s from hadronic event shapes in e+e- annihilation
J. C. Thompson
Physics , 1998,
Abstract: New studies of hadronic event shape observables in e+ e- collisions between 13 and 183 GeV CM energy have enabled the running of alpha_s to be confirmed and the validity of non-perturbative power-law corrections to be investigated. A more precise value of alpha_s(M_Z) with reduced theoretical errors has been reported from fitting 18 oriented event shape distributions measured in one experiment at the Z.
Gamma Radiation from PSR B1055-52
D. J. Thompson
Physics , 1998, DOI: 10.1086/307083
Abstract: The telescopes on the Compton Gamma Ray Observatory (CGRO) have observed PSR B1055-52 a number of times between 1991 and 1998. From these data, a more detailed picture of the gamma radiation from this source has been developed, showing several characteristics which distinguish this pulsar: the light curve is complex; there is no detectable unpulsed emission; the energy spectrum is flat, with no evidence of a sharp high-energy cutoff up to >4 GeV. Comparisons of the gamma-ray data with observations at longer wavelengths show that no two of the known gamma-ray pulsars have quite the same characteristics; this diversity make s interpretation in terms of theoretical models difficult.
Probing the Structure of Halo Nuclei
I. J. Thompson
Physics , 1997, DOI: 10.1088/0954-3899/23/10/011
Abstract: Our understanding of halo nuclei has so far relied on high-energy scattering and reactions, but a number of uncertainties remain. I discuss in general terms the new range of observables which will be measured by experiments around the Coulomb barrier, and how some details of the reaction mechanisms still need to be clarified.
